Description

This invention relates to the locking mechanism of the spindles, which stops the rotation of the spindle after yarn breakage.

The level of technology related to the invention

On modern ring spinning machines, the yarn is made by winding a twisted yarn on a spool, which is located on a rotating spinning spindle. The spindle rotates with the drive belt, which is driven by the main engine. When for some reason the yarn breaks, the spindle continues to rotate. But the yarn is not made.

Due to the fact that there is no pointer or system defining the break, the spindle continues to rotate idly (without producing yarn) until the operator determines that a break has occurred. When yarn breaks (while the spindle continues to rotate), the yarn that should be produced passes through the suction channel and ends up in waste; meanwhile, until the operator twists the yarn, the spindle continues to rotate without producing spinning products;

due to the fact that the yarn continues to rotate, the free end of the cotton yarn wound on the spool is wound, wiping the machine parts; these loose cotton ends are loss of production and lead to yarn breaks on the same machine or on other machines in the same room, i.e. one break of yarn leads to other breaks, increasing the total number of breaks on the machine; in order to take urgent measures against the increasing number of cliffs, the number of operators working on machine tools must increase, since the number of operators is determined by the standard number of breaks per machine;

when the number of breaks exceeds the standard, you have to reduce the speed of the machine, regardless of performance degradation, for the machines to work efficiently, or require operators to work overtime, working on fewer machines than usual to solve such a problem;

the operators stop the spindle by raising or lowering the spindle brake with their knees or hands, depending on the type of machine in order to carry out the necessary operations, and then release the brake in order to twist the yarn again.

Purpose of the present invention

The present invention has been developed with the following objectives:

stop the spindle immediately when the thread breaks;

prevent breaks of other fibers that occur when the ends of cotton yarn are flowing;

increase the speed of the ring machines;

reduce the number of operators per machine;

increase production efficiency (by increasing productivity);

reduce production costs.

Description of the invention

The main components of the automatic locking mechanism for the spindle ring spinning machine, improved in accordance with the present invention are:

a coil for creating a magnetic field, a metal insert (6) and its upper part (14), a locking mechanism (8 and 9), a stopper lever (7), a connecting component (15).

The magnetic field includes a part (2) with a winding, the outer part of a part (3) with a winding, a back box that covers the magnetic field coil (5) and a cover (4). The part for receiving a magnetic field has a winding. The coil (1) of the magnetic field creates a magnetic field, thanks to which the metal insert (7) moves.

The metal insert (6) has a plastic top (14). This plastic top (14) protects it from dust. The working principle of the device is based on the reciprocating movement of a metal insert in a magnetic field. When a magnetic field arises, the metal insert (6) is pulled in by this magnetic field and causes the locking lever (7) to operate. Thus, the locking mechanism (8 and 9) stops the spindle using the locking lever (7), which inhibits rotation. The working principle of this part is to retract the metal part into the magnetized part when a magnetic field occurs.

The locking mechanism shown in FIG. 12, consists of a plastic part (8) and a metal load (9) of predominantly spherical shape. The locking mechanism is connected to the locking lever (7), which is triggered by the movement of the metal insert (6), when the locking lever (7) moves, the T-shaped passage (12) on the brake mechanism also moves by means of the load located on it and mechanically is blocked. At this time, the power is turned off, and the lock is maintained.

The locking lever shown in FIG. 11, the levers of the rear connecting part compresses the spindle and is the element that stops the spindle. They are performed by the manufacturer of the ring machines on the locking lever (7). The plastic part containing the T- and Ι-shaped passages (12 and 13), which facilitate manual blocking, is pulled in or pushed out by the metal insert (6) to communicate movement to the braking device. The brake device is part of the machine.

The main connector (1) is the metal component that is used to assemble the locking mechanism for the spindle of the ring spinning machine improved in this invention on this machine. Those parts that were considered earlier are assembled at the main connection part (1) (Fig. 1, 2, 3, 4 and 5). These parts are attached to the ring machine after they are assembled together at the main connecting part (15).

The connecting component (15), which is part of plastic with passages and bolt holes, is an element for fastening other components to the machine.

The breakage sensor, which is used to determine the number of breaks that occur for any reason during the production of the yarn, works on the principle of determining the speed of the slider (the runners wind the yarn). As long as the speed of the slider is above 2400 rpm, no signal is sent to the control panel. If the speed falls below the 2400 rpm limit, the signal is sent to the control panel.

Upon receipt of this information, the control panel supplies energy from its electronic component

Then the metal insert, which makes a movement back and forth, is drawn into the center of the magnetic field due to the magnetic effect. Due to the fact that the locking lever (7) attached to the metal insert (6), is drawn into the center, the locking system (Fig. 12) passes through a T-shaped passage in the locking lever and locks the spindle. Meanwhile, the power to the system is turned off, and the system operates in a mechanical locking mode. The operator prepares the yarn for this spindle for start-up and releases the metal load with the hand (9), starting the process of twisting the yarn. In this case, the brake mechanism moves to its first position, since there is no magnetic field.
