Slipform paver

Description

BACKGROUND OF THE DISCLOSURE

Field of the Disclosure

The disclosure relates to a slipform paver, and to a method for the construction of ground pavements or structures by means of slipform pavers.

Description of the Prior Art

Slipform pavers are known, in particular from DE 199 57 048 (U.S. Pat. No. 6,481,924), which comprise at least one machine frame, travelling devices that are connected to the machine frame, and at least one conveying device. The conveying device can be used, for example, to transport concrete to a working device. The working device can be used to construct ground pavements or structures. The working device may, for example, be a concrete mold. The working device may be exchangeable and may also be alterable in position or extended. The travelling devices may be connected to the machine frame in such a manner that they can change their position in relation to the machine frame.

The conveying device may be connected to the machine frame in such a manner that the conveying device is pivotable, relative to the machine frame, at least about a horizontal axis and at least about a vertical axis, and is preferably movable translationally in at least one first direction. Actuators may move the conveying device about the respective axes and, if necessary, in the respective direction. The conveying device is movable, by means of the actuators, within a zone of movement defined in relation to the machine frame.

The conveying device comprises a material pick-up area for picking up concrete. The concrete is then transported, via the conveying device, to the working device, in particular to the concrete mold, which is used to construct the ground pavement or structure.

With the known slipform pavers, there is frequently the problem that the operator has to control both the slipform paver as such and the conveying device that is part of the slipform paver, which is used to convey the material that is placed in the concrete mold. There is thus an increasing requirement to simplify the operation of the conveying device.

When supplying the slipform paver with concrete, it is necessary that supply vehicles load the concrete onto the conveying device at a first end of the conveying device. The conveying device may, for example, comprise a pick-up device at the first end. When changing the supply vehicles, for example, it may be necessary to adjust the position of the first end of the conveying device in order to ensure continuous loading, while at the same time the position of the second end of the conveying device, where the material is transferred into the concrete mold, should not be changed at all or should be changed as little as possible.

On the other side, it may be necessary to keep the first end of the conveying device, where loading of the conveying device takes place, in a constant position while loading the slipform paver with concrete and to adjust the location of transfer of the material into the concrete mold in order to optimize filling of the concrete mold.

SUMMARY OF THE DISCLOSURE

It is therefore the object of the present disclosure to create a slipform paver and a method for the construction of ground pavements or structures by means of slipform pavers that simplify the operation of the entire slipform paver, in particular the operation of the conveying device.

The above mentioned object is achieved by the features of the claims.

The disclosure advantageously provides that at least one controller and at least one input device is provided, wherein the movement of at least one first location of the conveying device is specifiable at the input device, and that the actuators are controllable, by means of the controller, in such a manner that the first location of the conveying device performs the specified movement.

According to the present disclosure, at least one first actuator is provided, which is arranged and designed in such a manner that the conveying device is pivotable at least about the horizontal axis. Furthermore, a second actuator is provided, which is arranged and designed in such a manner that the conveying device is pivotable at least about the vertical axis.

Since the movement of at least one first location of the conveying device may be specified by means of the input device, and the actuators may be controlled by means of the controller in such a manner that at least the first location of the conveying device performs the specified movement, it is possible to optimally position the conveying device.

The first location may be formed by a point of the conveying device permanently stored in the machine control system. In this arrangement, the first location may particularly preferably be arranged at the first end of the transport conveyor or the second end of the transport conveyor.

However, the first location may preferably be selectable or settable by the operator.

Particularly preferably, multiple points along the extension of the conveying device may be stored in the controller, from which the operator may select which point is to form the first location. This allows the operator to determine which location or which point of the conveying device, respectively, performs the movement specifiable by the operator.

In this arrangement, it is particularly advantageous if at least the first end of the conveying device and the second end of the conveying device are selectable. This allows the operator to determine, prior to entering control commands, whether the first end of the conveying device or the second end of the conveying device performs the specified movement as the first location of the conveying device as a result of his control commands.

The operator may then determine the first end of the conveying device as the first location in order to be able to adjust the position of the pick-up location, where the material is loaded onto the belt conveyor, as easily as possible. This facilitates positioning of the pick-up location relative to a loading vehicle.

If the operator selects the second end of the conveying device as the first location, he can optimally adjust the position where the material is transferred to the working device in order to optimize loading of the concrete into the mold.

In addition, further points along the extension of the belt conveyor may be selectable as the first location by the operator in order to enable flexible positioning of the conveyor.

As an alternative to the selection of previously determined points along the extension of the conveying device, the controller may also be designed in such a manner that the operator may determine the first location freely along the longitudinal extension of the conveying device. This allows the operator in every operating situation to optimize positioning of the conveying device in any given location.

The movement performed by the first location of the conveying device is a movement relative to the at least one machine frame.

It is decisive that the movement of the first location of the conveying device, and not the movement of the actuators, is directly specified by means of the input device. The movement to be performed by the actuators is controlled based on an algorithm stored in the controller.

The stored algorithm takes into account the geometrical arrangement of the actuators, the axes, and the arrangement of the conveying device in relation to the machine frame.

The movement of the first location specified in the input device is translated into a coordinated actuation of the actuators by means of the controller so that the at least one first location performs the specified movement.

It is also possible that at least one third actuator is provided, which is arranged and designed in such a manner that the conveying device is movable translationally at least in the first direction. In this design, depending on the embodiment, the conveying device may be moved translationally in the first direction either as a whole or merely one end of the conveying device, which makes it possible to extend the length of the conveying device. Alternatively, both could also be possible.

The precise control of these movements is achieved by means of a controller and an input device. The movement of a specific location of the conveying device is specified at the input device. The controller processes these inputs and controls the actuators accordingly, so that the first location of the conveying device performs the desired movement. This arrangement permits flexible adjustment to different construction site conditions. The combination of pivotable conveying device, precisely controllable actuators and a user-friendly input device, which may be used to specify the movement of at least one location of the conveying device, can therefore represent a substantial improvement in the user-friendliness and flexibility of the slipform paver.

A controller is provided, which is connected to an input device. Said controller receives inputs from the input device and processes the same in order to control the movements of the conveying device. The controller may be connected to the actuators via electrical or electronic interfaces and enable coordinated control of the movement of the conveying device.

The movement of at least the first location of the conveying device may be specified at the input device. This means that the operator may enter specific movement commands, which may be interpreted and implemented by the controller. The input device may be connected to the controller via communication interfaces in order to ensure smooth transmission of the commands.

The actuators are controllable by means of the controller in such a manner that the specified movement of the first location of the conveying device is performed. This may be achieved by means of a precise interaction of control algorithms and actuators, which may ensure that the conveying device performs the desired movements in a precise and reliable manner.

In addition, the controller may also continuously monitor the position and movement of the conveying device, and it may also adapt the control commands accordingly in order to realize the specified movements.

The specified movement may be a direction of movement and/or a speed of movement and/or a predefined movement target.

The first location of the conveying device may be arranged at the first end of the conveying device or the second end of the conveying device.

The second location of the conveying device may be arranged at the first end of the conveying device or the second end of the conveying device.

The first location of the conveying device and the second location of the conveying device exhibit a distance to one another. This means that, if the first location of the conveying device is arranged at the first end, the second location of the conveying device is not arranged at the first end, and vice versa.

There may be at least one first area of collision definable relative to the machine frame, wherein the actuators are controllable, by means of the controller, in such a manner that the conveying device cannot be moved into the at least one first area of collision.

The area of collision may be an area within a zone of movement. The zone of movement may be the space, relative to the machine frame, within which the conveying device can theoretically move, and is necessarily determined by the design of the conveying device and the actuators that move said conveying device.

The area of collision may be an area into which the conveying device should not move. Said area may be an area, for example, in which a collision of the conveying device with at least one object may occur. Said object may, for example, be a part of the slipform paver, such as, for example, a travelling device. In this case, the object would actually be located within the area of collision. On the other hand, this may also be a theoretical danger of a collision with an object. On a carriageway, for example, there could be an area located within the zone of movement, in which vehicles, for example, site vehicles, or other objects may be moved. In this case, a specific area of collision may be defined, in which a collision may theoretically occur.

The position of the conveying device in the zone of movement, in particular the position of the conveying device relative to the area of collision, may be determinable based on the adjustment position of the actuators. The controller may be designed to emit a control signal as soon as it is established by means of the controller that the conveying device comes within a specified distance from the area of collision.

The machine frame may be arranged within the at least one first area of collision so that the actuators may at least be controllable, by means of the controller, in such a manner that the conveying device does not collide with the machine frame.

At least one second location of the conveying device relative to the machine frame may be specifiable at the input device, wherein the actuators may be controlled, by means of the controller, in such a manner that the second location may remain essentially in a specified position relative to the machine frame.

In this arrangement, the second location may remain essentially in the specified position even if the first location of the conveying device performs the specified movement.

In this arrangement, remaining essentially in a specified position may be understood to mean that the at least one second location of the conveying device does preferably move away by no more than 50 cm, in particular by no more than 25 cm, particularly preferably by no more than 10 cm from a specified position relative to the machine frame. It is particularly preferred, however, that the at least one second location of the conveying device does not move away at all from the specified position relative to the machine frame.

Similar to the first location, the second location may also be a position along the longitudinal extension of the conveying device permanently stored in the machine control system.

If, for example, the first end of the conveying device is specified in the controller as the first location, the second end of the conveying device may be determined as the second location in a preferred embodiment. If the second end of the conveying device is determined as the first location, the first end of the conveying device may be determined as the second location.

However, the second location may preferably be selectable by the operator.

The second location may preferably also be selectable and determinable from a plurality of points along the longitudinal extension of the belt conveyor. The machine operator may thus select which points of the belt conveyor are to remain essentially stationary during the movement of the first location. This makes positioning easier, since the operator only has to concentrate on controlling the point to be moved selected as the first location without having to take into account the effects of the movement on the second location.

It is particularly preferred if pairs of points along the longitudinal extension of the longitudinal axis of the belt conveyor are stored in the control system by the operator as pairs of first locations and second locations, and the operator may further select which of the points of the pair of points is to be selected as the first location and/or as the second location.

Such a pair of points is then selectable by the operator. The operator may then further select which of the points is to follow the movement specified at the operating device as the first location, and which point is to remain essentially in a specified position as the second location.

Such a pair of points may be formed, for example, by the first end of the conveying device and by the second end of the conveying device. The operator may select the point of pairs in a first step and then determine whether the first end of the conveying device or the second end of the conveying device is determined as the first location and may therefore subsequently be positioned by means of the operating device. The other of the first end of the conveying device and second end of the conveying device is then determined as the second location. The operator may now freely position the end of the conveying device determined as the first location, and the other end of the conveying device determined as the second location remains essentially in its position despite the free positioning of the first end. Positioning of the individual ends of the conveying device is thus considerably simplified, as it is no longer necessary to take into account the effects of the adjustment operation on the other end of the conveying device.

As a matter of principle, a single pair of points only may also be stored in the control system, and the operator merely has to select which of the two points is determined as the first location and/or which of the points is determined as the second location.

Alternatively, the position of the second location along the longitudinal extension of the conveying device may also be determined independent of the first location.

As a matter of principle, it is also conceivable to make the second location freely determinable by the operator along the longitudinal extension of the conveying device.

The actuators may be hydraulic, pneumatic or electrical actuators.

The conveying device may be directly or indirectly connected to the machine frame at least via one first parallelogram guide, wherein the conveying device may be pivotable about the horizontal or vertical axis by means of said first parallelogram guide.

The conveying device may be directly or indirectly connected to the machine frame at least via one first articulation joint, wherein the conveying device may be pivotable about the horizontal or vertical axis by means of said first articulation joint.

At least one third actuator may be provided, which may be arranged and designed in such a manner that the conveying device may be movable translationally in at least one first direction. In this design, depending on the embodiment, the conveying device may be moved translationally in the first direction either as a whole or merely one end of the conveying device, which makes it possible to extend the length of the conveying device. Alternatively, both could also be possible.

The conveying device may comprise a transport conveyor.

A method may be provided for the construction of ground pavements or structures by means of a slipform paver, which comprises at least one machine frame, to which at least one conveying device is connected, wherein the conveying device is pivotable, relative to the machine frame, at least about a horizontal axis and at least about a vertical axis, wherein at least one first actuator may pivot the conveying device at least about the horizontal axis, and at least one second actuator may pivot the conveying device at least about the vertical axis, wherein the movement of at least one first location of the conveying device is specified at at least one input device, and the actuators are controlled, by means of a controller, in such a manner that the first location of the conveying device performs the specified movement.

A second location may be specified relative to the machine frame, wherein the actuators may be controlled, by means of the controller, in such a manner that the second location may remain in a specified position relative to the machine frame.

At least one first area of collision may be defined relative to the machine frame, wherein the actuators may be controlled, by means of the controller, in such a manner that the conveying device is not moved into the at least one first area.

The machine frame may be arranged within the at least one first area of collision so that the actuators may be controlled, by means of the controller, at least in such a manner that the conveying device cannot collide with the machine frame.

DETAILED DESCRIPTION

FIG. 1 shows a slipform paver 1. A slipform paver can be used to construct ground pavements or structures. The slipform paver 1 can move in the direction of operation A.

The slipform paver 1 comprises at least one machine frame 2. Travelling devices 4 are connected to the machine frame 2. Furthermore, at least one conveying device 6 is provided. The conveying device 6 can be used, for example, to transport concrete to a working device 12 (FIG. 2). The working device can be used to construct ground pavements or structures. The working device may, for example, be a concrete mold. The working device may be exchangeable and may also be alterable in position or extended. The travelling devices 4 may be connected to the machine frame in such a manner that they can change their position in relation to the machine frame.

A slipform paver 1 is depicted in FIG. 1, in which the longitudinal members 81 of the machine frame 2 are variable in length. Furthermore, the machine frame 2 also comprises a machine frame part 200, which is variable in length in the longitudinal direction 230 and in the transverse direction 220. Different working devices 12, for example, concrete molds of different shapes, may be attached to said machine frame part 200. These may be positioned differently by means of the machine frame part 200.

The conveying device 6 may be connected to the machine frame 2 in such a manner that the conveying device 6 may be pivotable, relative to the machine frame, at least about a horizontal axis and at least about a vertical axis. As depicted in the embodiment, the conveying device 6 may also be movable translationally in at least one first direction relative to the machine frame.

Material may be picked up by means of the conveying device 6 and conveyed into the working device 12 used to construct the pavement or structures.

The conveying device 6 is depicted in more detail in FIG. 2, where the material is picked up at the first end 8 and is placed in the working device 12 designed as a concrete mold at the second end 10.

A controller 62 is provided in order to control the actuators. The controller 62 may be generally described as an automatic controller. Said controller 62 is connected to an input device 82, which can be used to specify the movement of a first location 9 of the conveying device 6. The input device 82 allows the user to enter the desired movement of the conveying device 6, whether in the form of a direction of movement, a speed of movement or a predefined movement target. The input device 82 may be generally referred to as an input interface 82.

The actuators are controllable in such a manner that the first location 9 of the conveying device 6 performs the specified movement. This is made possible by the controller 62, which receives the signals from the input device 82 and forwards the respective commands to the actuators.

The first location of the conveying device 6 may be any given location on the conveying device 6. As in the embodiment depicted, it may, for example, be at the location of the first end 8, where the material is loaded onto the conveying device. However, the first location of the conveying device 6 could alternatively also be at the location of the second end 10.

In addition, a second location 11 of the conveying device 6 may be specified in relation to the machine frame 2. The actuators may be controllable in such a manner that said second location remains in a specified position relative to the machine frame 2.

The second location of the conveying device 6 may also be any given location on the conveying device 6. As depicted in the embodiment, the second location of the conveying device 6 may, for example, be a location at the second end 10, where the material is transferred into the working device 12 designed as a concrete mold.

In this way, for example, when changing a transport vehicle that provides the concrete to be placed, the first location 9 of the conveying device 6 may be moved in order to enable continuous loading and, at the same time, material may be placed in the concrete mold 12 at the second location 11 of the conveying device 6 without changing the position.

Alternatively, if the first location 9 of the conveying device 6 is arranged at the location of the second end 10, the second location 11 of the conveying device 6 could also be arranged at the first end 8.

The input device 82 may be arranged separately from the controller 62, or the input device 82 and the controller may be designed as a single unit. The input device may be arranged on the slipform paver or separately from the same.

The conveying device 6 is depicted in more detail in FIG. 3. The conveying device 6 comprises a belt conveyor or transport conveyor 14, respectively, which is shown in FIG. 3. The conveying device 6 may be generally referred to as a conveyor 6. The belt conveyor 14, and therefore the conveying device 6, may be pivoted about a horizontal pivoting axis 19 by means of at least one first actuator 22. Furthermore, the conveying device 6 may be pivoted about a vertical pivoting axis 36 by means of a second actuator 34. Moreover, the conveying device 6 may also be movable translationally in at least one first direction 16 by means of a third actuator 18. In this design, depending on the embodiment, the belt conveyor 14 may be moved in the first translational direction 16 either as a whole or merely one end of the belt conveyor 14, which makes it possible to extend the length of the belt conveyor. Alternatively, both could also be possible.

Furthermore, the conveying device 6 is arranged on a parallelogram guide 106, which can be used to adjust the entire conveying device 6 by means of an additional actuator 24 not depicted in FIG. 3. This will be explained in more detail with reference to FIG. 7. The parallelogram guide 106 is arranged on the machine frame 2.

FIG. 4 shows the embodiment according to FIG. 3 with the conveying device moved in the translational direction 16, in which the conveying device as a whole has been moved in the translational direction 16.

Furthermore, in FIG. 4, the at least first actuator 22 is depicted, which may pivot the conveying device 6 about the pivoting axis 19, wherein the axis 19 is preferably a horizontal axis. In this design, the pivoting axis 19 is preferably arranged below the belt conveyor 14. As depicted in the embodiment, the pivoting axis 19 may be arranged in the upper third of the conveying device 6. In a further preferred embodiment, the pivoting axis 19 may be arranged in the area of the middle third of the conveying device 6. In the embodiment depicted, the depicted first actuator 22 is mounted on a connection element 100 to pivot about a pivoting axis 102. The connection element 100 is arranged on a parallelogram guide 106. The first actuator 22 is furthermore connected to the conveying device 6 on a second end to pivot about a pivoting axis 103. The conveying device may also be movable translationally along the axis 36 manually or by means of an additional actuator.

FIG. 5 shows a view of the embodiment from below. However, the belt conveyor is not depicted for reasons of clarity. The view shows the at least one first actuator 22, the at least one second actuator 34 and the at least one third actuator 18. The second actuator 34 may pivot the conveying device 6 about the vertical pivoting axis 36. The pivoting axis 36 preferably intersects the belt conveyor. Furthermore, the pivoting axis 36 may extend through the pivoting axis 19. This can also be inferred from FIG. 4. In the embodiment depicted, the second actuator is connected, at a first end, to the parallelogram guide 106. At a second end, the second actuator 34 is connected in a pivotable manner to a connecting link 108, which is in turn connected to a hollow column 110, which is connected to the conveying device 6. By operating and extending or retracting the second actuator 34, respectively, the hollow column 110, and thus the conveying device 6, may be pivoted about the pivoting axis 36.

Furthermore, an optional additional actuator 24 is also depicted in FIG. 5. It can be used to adjust the entire conveying device 6 with the parallelogram guide 106. The parallelogram guide 106 is arranged on the machine frame 2.

If the machine does not comprise the optional additional actuator 24 and the parallelogram guide 106, the axis 36 may also be arranged on the machine frame.

Since the conveying device may be flexibly moved and positioned within the zone of movement at least by means of the actuators 22, 18, 34, 24, material can be reliably transported to the working device by means of the conveying device 6. The pick-up location, where the material is transferred to the conveying device 6, is flexible in this design, as is the position where the material is transferred to the working device 12.

As an alternative to the parallelogram guide 106, the axis 36 may also be arranged to be linearly movable, preferably movable in transverse direction of the machine, perpendicular to the direction of operation A.

Horizontal within the meaning of the present disclosure does not necessarily mean horizontal relative to the ground surface but horizontal to a plane defined by the longitudinal and transverse axis of the machine frame.

A controller 62 (depicted in FIG. 2) is provided in order to control the movements of the at least one first location 9 of the conveying device 6. As explained earlier, the first location of the conveying device 6 may be any given location on the conveying device 6. As in the embodiment depicted, it may, for example, be at the location of the first end 8, where the material is loaded onto the conveying device.

The controller 62 is connected to the actuators 22, 18, 34, 24 and controls their movements based on the inputs that are made via an input device 82. The input device is also depicted schematically in FIG. 2. The input device 82 may be used to specify the movement of at least one first location of the conveying device 6. The controller 62 ensures that the actuators 22, 18, 34, 24 perform the specified movement so that the first location of the conveying device 6 performs the desired movement and/or reaches the desired position. If additional actuators are provided, the controller 62 may also control said additional actuators in order to control the first location 8 of the conveying device 6.

FIG. 6 shows the conveying device according to FIG. 4, but in adjusted position. In FIG. 6, the at least first actuator 22 has been adjusted in comparison with FIG. 4. FIG. 6 furthermore depicts a zone of movement 40. In this arrangement, the zone of movement 40 is the space in which the conveying device 6 may be moved by moving the at least first, second and third actuators. It is therefore the space within which the conveying device 4 can theoretically move. The zone of movement 40 is defined in relation to the machine frame. If the slipform paver, and therefore the machine frame, moves forward, the zone of movement 40 will, as a result, also move forward. The zone of movement 40 is necessarily determined by the design of the conveying device and the actuators moving said conveying device. FIG. 6 only depicts the zone of movement in side view.

An area of collision 60 may now be definable within the zone of movement. The area of collision 60 is an area within the zone of movement 40 into which the conveying device 6 should not move. Said area of collision 60 may, for example, be an area in which a collision of the conveying device 6 with the machine frame 2 or a travelling device 4 or at least any other object may occur.

FIG. 7 shows a top view of the conveying device 6. However, the belt conveyor 14 is not depicted for reasons of clarity. Said top view depicts the optional additional actuator 24. The additional actuator 24 may pivot the entire conveying device 6 in parallel. In the present embodiment, the optional additional actuator 24 pivots the conveying device by means of the parallelogram guide 106. The two links 26 and 28 are depicted in FIG. 7, each of which pivots about an axis of rotation 30 and 32.

The zone of movement 40 and the optional area of collision 60 are depicted in top view in FIG. 7. The zone of movement 40 and the zone of collision are, however, only depicted in a specific horizontal plane. It is not possible to depict the spatial extension of the zone of collision 60 and 40 outside said plane in this top view.

The conveying device 6 may be moved within the zone of movement 40 defined relative to the machine frame 2 by means of the at least one first actuator 22, at least one second actuator 34 and at least one third actuator 18. As depicted in the embodiment, the conveying device 6 may optionally also be moved within the zone of movement 40 defined relative to the machine frame 2 by means of the at least one third actuator 18. The zone of movement 40 is depicted in FIGS. 6 and 7. If additional actuators are provided such as, for example, the additional actuator 24, the zone of movement 40 is the space in which the conveying device 6 may be moved by moving the first actuator 22, second actuator 34, third actuator 18 and additional actuator 24. It is not excluded in this arrangement that more than one additional actuator may be provided. For the purpose of defining the zone of movement, all degrees of freedom of the conveying device and therefore all actuators involved in the adjustment operation have to be taken into account.

Furthermore, the optional area of collision 60 is also depicted in the zone of movement 40. The optional area of collision 60 is the area within the zone of movement 40 into which the conveying device 6 should not move. Said area of collision 60 may, for example, be an area in which a collision of the conveying device 6 with the machine frame 2 or a travelling device 4 or at least any other object may occur. In general terms, the area of collision defines a partial area of the zone of movement into which a movement of the conveying device 6 should not occur.

A controller 62 and an input device 82 are depicted in more detail in FIG. 8.

The depicted controller 62 preferably comprises a storage device 80. The controller 62 may furthermore be connected to an input device 82.

The input device 82 may be used to specify the movement of at least one first location of the conveying device 6. The actuators provided are controllable by means of the controller 62 in such a manner that the first location 8 of the conveying device 6 performs the specified movement.

It is also possible to transmit sensor signals 84 to the controller 62. Said sensor signals 84 may be, for example, the position signals of the conveying device 6. It is also possible to transmit additional sensor signals 86 to the controller 62. Said additional sensor signals 86 may be the sensor signals relating to the position and/or size of the working device and/or travelling devices 4. The controller 62 may emit at least one control signal 88, which will be described in more detail below.

The input device 82 may be used to specify the movement of at least one first location of the conveying device 6. The actuators provided are controllable by means of the controller 62 in such a manner that the at least first location 8 of the conveying device 6 performs the specified movement.

For this purpose, control signals 88 may, for example, be transmitted to the actuators, which control the actuators in such a manner that the at least one first location of the conveying device performs the movement specified at the input device.

The specified movement may be a direction of movement and/or a speed of movement and/or a predefined movement target.

For clarification of the operating principle of the slipform paver according to the disclosure and of the method according to the disclosure, the slipform paver is again depicted in FIGS. 9 and 10 in a merely roughly schematic manner and with the relevant assembly groups only. In the embodiment depicted, the conveying device 6 comprises a belt conveyor or transport conveyor 14, respectively.

FIG. 9 shows the slipform paver 1 in operation in the direction of operation A. The slipform paver receives the concrete to be paved from a supply vehicle 400 via a supply device 41 at the first end of the conveying device 6. The concrete is then conveyed via the belt conveyor 14 to the second end 10, where the concrete is placed in the concrete mold 12.

A second supply vehicle 400′ with a second supply device 41′ is depicted in FIG. 9 in dashed lines only. When the supply of concrete provided by the first supply vehicle 400 has been used, it is necessary to change the supply vehicle. Due to the intended, ideally non-stop supply with concrete, the second supply vehicle 400′ may be brought close to the slipform paver 1 in parallel to the first supply vehicle 400.

As depicted in FIG. 2, the first end 8 of the belt conveyor 14 is determined as the first location 9, and the second end 10 of the belt conveyor 14 is determined as the second location 11. It is irrelevant in this context whether said determination was stored in the control system or said determination was made in advance by the machine operator.

In order to switch the supply of concrete from the first supply vehicle 400 to the second supply vehicle 400′, it is now necessary to position the first end 8, where the concrete is picked up by the slipform paver, below the supply device 41′. For this purpose, the operator may make a control input at the input device 82 that initiates a movement of the first location 9 of the conveying device 6, which in the present embodiment is arranged at the first end 8, to the left as seen in the direction of travel. The control unit 62 now coordinates the actuation of the actuators 22, 18, 34, 24 in such a manner that the first location 9 of the conveying device 6 is pivoted into the position below the second supply device 41′ depicted in FIG. 10, while the second location 11 of the conveying device, which in the present embodiment is arranged at the second end 10, retains its position above the concrete mold 12 in order to ensure continuous placement of the concrete into the mold.

Owing to the arrangement of the actuators depicted in FIGS. 3 to 7, it is not sufficient for this purpose to move one of the actuators, but rather a coordinated movement has to be made. In the example depicted, for example, the links 28 and 26 (not depicted in FIGS. 9 and 10) of the parallelogram guide 106 are pivoted by means of the actuator 24 (not depicted in FIGS. 9 and 10) in order to move the axis 36 to the left as seen in the direction of travel. The actuator 18 must also be actuated at the same time, however, in order to move the location 8, where the material is picked up, along the longitudinal axis of the belt conveyor 14 towards the location 10. In addition, it may also be necessary to adjust the inclination of the belt conveyor 14 via the actuator 22, or to pivot the conveyor via the actuator 34.
