Description

The invention relates to textile industry and relates to devices for shifting packages before removing them from the spindles of ring spinning and twisting machines.

The purpose of the invention is to increase the reliability of operation when shifting packages of any mass.

Figure 1 shows a general view of the device for shifting the packings before they are removed from the spindles of the machine; figure 2 - section aa in figure 1; on fig.Z - view B in figure 2.

The device contains spring-loaded rods 1, vertically mounted between the spindles 2 in the holes of the spindle beam 3 of the twisting machine with the possibility of vertical movement. At the upper end of each rod under the packings 4 of the machine horizontally fixed by a middle part a strap 5, each end of which has sleeves 6. Each the sleeve is mounted coaxially with the spindle 2 and at its upper end face, by means of horizontal fingers 7, at least three rollers 8 are installed with the possibility of free rotation on them. At the lower end of each rod, the roller 10 is mounted with the possibility of free rotation by means of a horizontally placed finger 9. The finger 9 is placed in the slot 11 of the bracket 11, which is fixed on the spindle bar 3, and is pressed against the bracket by the rod spring 13

On the bottom shelf of the spun beam 3, a slider 14 is installed with surfaces 15 inclined to the horizontal. The slider is mounted console on an endless traction element 16 in the form of a drive train 17 of the device with the ability to move along the spindle beam and interact with the rollers 10 rods. The chain can be set at a distance of several slides from one another.

The drive of the device has limit switches 18 and 19 for stopping the spindles of the machine after shifting the packings on them.

The device works as follows.

At the end of the operating time of the packings 4, the device actuator 17 is turned on, which, using an endless traction chain 16, moves the slide 14. The slide slides off the limit switch 18 and.

moving along a row of spindles 2, interacts with one surface 15 in series with each roller 10, and through the finger 9, overcoming the resistance of the spring 13, raises the rod 1 with the bar, which through the rollers 8 on the bushings acts on the lower surface of the flange 20 of the package 4

10 and shifts them from the spindles 2. As the slider 14 moves to the next stem; The airtight spring is lowered to its original position. Slider, reached the limit switch 15 l 19, turns off the drive 17 and the spindle motor.

Before the next removal of the developed packages, the working cycle is carried out by moving the slider in the opposite direction.

20 side. The bracket 11 simultaneously serves as a guide for the slider 14 and the finger 9 and prevents the rotation of the rods 1 around its axes.

With the vertical movement of each sleeve along the rotating spindle, a combination of translational and rotational movements occurs, which leads to the movement of the inner surface of the package barrel along the helix relative to the outer surface of the spindle spindle. The packing shift relative to the spindle occurring in this way is similar to the movement of the nut along the

.. screw, which leads to a significant reduction in the magnitude of the shear forces of the package from the rotating spindle. This also contributes to the rollers at the ends of the sleeves, which provide easier

Qing rotation of the package relative to the spindle and eliminates the possibility of damage to the package.

The presence of sleeves on the slats allows the slats to be perceived by much greater force. The cantilever installation of the slider allows it to be made wider and, accordingly, longer in contact with the rollers, which helps to reduce the specific pressure on the rollers and increase the reliability of the device. In addition, the cantilever positioning of the slider on the chain allows the chain to be moved to the edge of the spindle beam, which contributes to improved convenience, maintenance and repair of the device.
