SU1602892A1 - Stand for warp beams of sizing machines - Google Patents

Abstract

The invention relates to weaving and improves the quality of the weaving of weaving in the processing of warp shafts by maintaining the same tension for the warp shafts for all warp shafts. This is achieved in that the warping shafts 9 are driven by the rolling rollers 7 containing pneumatic chambers 8, the internal cavities of which are connected by a system of channels to a source of compressed air through pressure regulators, which in turn are connected to a tension sensor of the warp threads. At the same time, tension sensors are installed for each warp shaft separately. 2 Il.

Description

The invention relates to the textile industry and can be used on sizing, distillation and emulsion machines for the preparation of weaving ·

The purpose of the invention to improve the quality of winding weaving Navoi by ensuring the constancy of the speed of the warp.

Figure 1 shows a diagram of the rack for the warmer shafts of the sizing machine; figure 2 - rolling shaft with pneumatic chambers, section.

The stand consists of a pulling pair 1 kinematically connected by a shaft 2, a gearbox 3, a main shaft 4, worms 5 (figure 2) and worm wheels 6 with rolling shafts 7, on the annular pneumatic chambers 8 (figure 2) which are based on the main shaft 9 body winding. The main shafts 9 · axles 10 installed in. guides 11. The chambers 8 are connected through an air channel 12 (Fig. 2), a longitudinal hole in the axis ^ of the expanding shaft, an air pipe 14 and a pressure regulator 15 with a central pneumatic pipe 16 of the pressure source. With the pressure regulator 15 also svya _(Zano through signal supply yarn tension sensor control device bases system consisting of a lever 18, the roller 19 and the controller 20 positions. The axis 13 of the Print shaft 7 (Figure 2) comprises a crossbar 21, which is attached to shroud 22.

The device operates as follows.

From the pulling pair, the gearbox 3, the main 5 and the worm wheels are given rolling measures 8 (figure 2), on which warping shafts 9, which form friction pairs with cameras 8, rely on their windings. In this case, the main shafts are rolled with a speed proportional to 10 through the shaft 2, the shaft 4, the worms move to the passes 7, on the channel diameter of the pneumatic chamber. The warp threads from all warping shafts 9 enter the pulling shaft 1, while skirting the rollers 19 of the warp tension sensors of the warp according to the number of warping shafts. When the tension of the threads coming from one of the warping shafts changes, the lever 18 deviates and the signal from the sensor position controller 20 enters the pressure regulator .15, which regulates the pressure in the chambers 8. The pressure change causes an increase or decrease in the diameter of the elastic shells and, accordingly, the rolling speed.

An individual system for regulating the rolling speed of each warp shaft allows you to maintain a given uniform tension of all warp threads, regardless of their diameter and the winding tension of the threads on the warp shaft. The initial rolling speed is set in accordance with the pulling speed. The presence of chambers 8, in addition, damage to the threads.
