SU19504A1 - Adaptation to spinning and twisting machines for raising and lowering the annular plank or spindle - Google Patents

Description

The invention relates to a device which is used in the spinning and twisting machines for lifting the annular plate and depending on the build-up of the coil. The adjustment is made by means of a mechanism consisting of a screw coupled to a worm wheel, which is on the same axis as the drum, which engages the chain that controls the lifting and lowering of the ring bar. In the proposed adaptation, the lowering and raising of the ring bar or spindle of the spinning or twisting machines is carried out by means of a bridge, which has a vertical movement from the eccentric rotated by the actuator and acting with an asterisk on it to a chain, one end of which is attached to the ring bar or spindle and another it is fixed to an asterisk mounted either on the bridge or on the frame of the machine.

- In FIG. 1 shows a view of a double-sided spinning machine on the inner side of the main wall of the frame; FIG. 2 is a front view of the spinner; FIG. 3-b show modifications of the device with the proposed device.

In ordinary spinning machines

ring strap I is raised up and down relative to spindle beam 2.

This movement is controlled by an exhaust or feed mechanism 3. To this end, the main drive shaft 4 of the mechanism 3 is provided with a wheel driving a screw wheel b mounted on a vertical shaft 8 rotating in bearings 7 fixed on the main side wall 12 beds. At the lower end of the shaft 8 there is a bevel gear 9, which engages with the bevel wheel 10. The latter rotates on an axis 11 fixed in the main wall 12 of the machine, and causes the eccentric 13 to rotate, which hooks to the roller 14. In the proposed device roller 14 is set. Chen on bridge 1, moving along two columns 16 with the help of sleeves 17. Columns 16 are fixed in shoes 18, mounted on the bottom of the main wall 12 of the bed. On bridge 15, shaft 20 is strengthened with an asterisk 19, which at the ends of the bridge 25 stroke can be continued to rotate further with the aid of a worm gear 21, a screw worm 22 and a hand wheel 23. On an asterisk 9 at point 25, pep 24 is strengthened, the second end of which is thrown through the chain

The wheel 26 is attached to the ring lanka 1. The wheel 26 sits on the shaft 27 passing through the entire length of the machine and has several sprockets 28 through which the chains 29 are slung, providing parallel movement of the ring bar 1.

If the yarn coils are to be cylindrical, the chain 24 is uncoupled from the sprocket 19 and the uncoupled end is attached to the bolt 30 fastened in the wall of the frame. The worm is then disconnected from the wheel 21 to 22. As a result, the sprocket 19 starts to work, as an idler pulley, guides the envelope of its chain 24. In this case, with a slight movement of the bridge 15, the annular rail moves in a vertical direction two times greater than the above. case.

If the annular plank must remain stationary and the spindle beam is moved, then the chain 24 is respectively attached to the spindle beam.

In the cases described above, the chain is directly attached to either the ring bar or the spindle beam.

In the device of FIG. 3 difference from that shown on the left part of FIG. 1 The ring strap 1 is moved in the usual way on the gear rods 31 passing through the spindle beam 2 and engaging with the gear wheels 33 sitting on the shaft 27. The chain 24 is attached at one end at point 55 to the pulley 46 fastened close to the main wall, and rotates a shaft 27 extending along the entire machine. In the device shown in FIG. 4, representing a modification of the device of the right part of FIG. 1: the end of the chain 24 is fixed at point 34, and the ring bar 1 is moved, as before, by the gear wheels 33 and the gear bars 31. Referring to FIG. 5 drive ring plate occurs; in the same way as AND; in fig. 4, but the end 35 of the chain 24 is fixed to the pulley 36, which can be driven by the worm wheel 37 by means of a screw 38 and the control wheel 39. This mechanism serves to further advance the drive as the coil grows.

A device for lifting the spindle beam 2 is shown in FIG. 6. The beam slides with the aid of the brackets 40 along the fixed columns 41, to which the toothed rods 42 are attached. Through all the arms of the spindle beam passes the shaft 43, which is mounted on each of the columns 41, along the toothed wheel 44 interlocking with the toothed bar 42. At the end of the shaft 43, close to the main wall of the frame, a pin 45 is fastened, through which the chain 24 is attached, attached at the end to the pulley. The weight of the spindle beam is expediently balanced by a counterweight, not shown in the drawing. Continuing the advancement of the circuit during coil buildup is accomplished by the same mechanism as shown in FIG. five./

The subject of the patent.

Adaptation to the spinning and twisting machines for raising and lowering the annular plank or spindle beam, characterized by the use of a bridge 15, moving along vertical guides using the eccentric 13 usually used for this purpose and operating an asterisk 19 mounted on it to a chain 24, one end of which attached to the annular plank or to the spindle beam, and the other end to the asterisk 19 or to the asterisk 36, which is rotatably fixed on the machine frame
