Automatic Ring (Yarn Machine) Spindle Stopper

Description

RELATED FIELD OF THE INVENTION

This invention is related to a spindle stopper which stops the spinning spindle after yarn breakage.

PRIOR ART RELATED TO THE INVENTION

On the current ring yarn machines yarn is produced by winding up the twisted strand on a cop which is on the revolving spindle. Spindle is revolving by the help of driving belt which takes power from the main motor. If there is a yarn breakage because of some reason, the spindle goes on revolving. Meanwhile there is no yarn production

Since there is no sign or system in order to notice the breakage, the spindle revolves in vain (without any yarn production) until the operator comes to realize the breakage. By the breakage of the yarn (during the revolving of the spindle in vain);

• • the yarn which must have been produced flows through a pnomofil suction canal and goes waste. Meanwhile until the operator joins the yarn by twisting, the spindle revolves without any yarn production.
  • since the yarn goes on revolving, the winding yarn on the cop with a free end causes cotton flies by rubbing against some parts of the machine. These cotton flies are loss of production and cause yarn breakages on the same machine or on the other machines in the same room thus yarn breakage causes more then one breakage and this increases the total number of breakages on the machine. In order to take action to the increased number of the breakage in a short time the number of operators around the machine must be increased since the number of the operators are determined according to the standard number of the breakages.
  • when the number of the breakages exceed the standards, speed of machines are decreased without paying attention to the loss of production in order to make the machines run efficiently or make operators work overtime to deal with less machines than usual to solve the problem.
  • operators stop the spindles by lifting or lowering spindle brakes by their knees or hands manually according to the type of machines in order to make the necessary operations and then make them loose to twist the yarn again.

THE AIMS OF DEVELOPING OF THE INVENTION

By developing of this invention;

• • when there is a yarn breakage, to make the revolving spindle stop immediately,
  • to prevent other yarn breakages caused by broken yarn's cotton flies, to run the ring machine faster,
  • to decrease the number of operators per machine,
  • to increase the efficiency (by increasing the productivity),
  • to reduce costs,
    are aimed.

EXPLANATION OF THE INVENTION

The main components of the automatic ring (yarn) machine spindle stopper improved by this invention are below.

• • Magnetic field coil
  • Inserting metal (6) and its top (14)
  • Locking mechanism (8 and 9)
  • Stopping arm (7)
  • Connection component (15)

Magnetic field consists of coiled part (2) exterior part of the coiled part (3) rear box which covers the magnetic field coil (5) and a cover (4). In order to make magnetic field, the coiled part is covered by wires. Magnetic field coil (1) makes magnetic field in order to give movement to the inserting metal (7).

Inserting metal (6) contains a plastic top (14). This plastic top (14) is to protect it from dust. The working principle of inserting metal is to move forward and backward inside the magnetic field. When there is a magnetic field, the inserting metal (6) is pulled inside by this magnetic field to make the stopping arm (7) work. Thus knocking mechanism (8 and 9) stops the spindle by the stopping arm (7) which applies brake. The working principle of this part is to pull the metal part into the magnetized part by making magnetic field.

Locking mechanism which is shown on the FIG. 12, consists of plastic part (8) and preferably ball-shaped metal (9) weight. Locking mechanism is connecting to a stopping arm (7) which works by the movement of inserting metal (6) when the stopping arm (7) makes a move, the T canal (12) on the brake mechanism also makes a move by the help of weight on it and make the mechanically locked. During this time the energy is cut off and the lock becomes mechanically on.

Stopping arm which is shown on the FIG. 11 (by rear connection part arms shown on the FIG. 11 squeeze the spindle) is the part which makes the spindle stop. These are made by the ring machines producers on the stopping arm (7). There is a plastic part (that contains T and I shaped canals (12 and 13) which makes the manual locking) which is pulled and pushed by inserting metal (6) to give a movement to the brake apparatus. The brake apparatus is a part on the machine.

The Main connection (1) is a metal component which is used to assemble the ring machine spindle stopper—improved by this invention—to the ring machine. The parts which mentioned above are assembled on to the main connection part (1) (FIGS. 1,2,3,4 and 5). These parts are assembled to the ring machine after joining together on the main connection part (15).

Connection component (15) which is a plastic part with canals and bolt holes on it is a mechanism to obtain the other components assembled to the machine.

The breakage sensor which is used to determine the number of breakages because of any reason during the production of yarn on the ring machine works in the principle of detecting the traveler (Travelers make the yarn wind up on to kops)'s speed. As for as the traveler's speed higher than 2400 RPM, no information is sent to the main board. If the speed is below the limit 2400 RPM, information is sent to the main board.

With this information the main board send energy from it's own electronic component to the coiled part (2). During this time magnetic field makes magnetic field on the coil. Then the inserting metal that gives movement to forward and backward is pulled into the centre of magnetic field by the magnetic effect. Since the stopping arm (7) attached to the inserting metal (6) is pulled into the centre, the locking system (FIG. 12) moves through the T canal on the stopping arm and locks the spindle. Meanwhile the energy of the system is cut off, and the system works by the method of mechanical locking. Operator prepares the yarn system of this spindle and release the metal weight (9) loose by his hand in order to give way to the yarn twisting process. In this case brake mechanism turns into it's first situation since the magnetic field is not on.
