Abstract

The invention relates to the production of rubber technical products and is intended for the assembly of rubber cord tapes, in particular drive belts. The purpose of the invention is to expand the technological capabilities of the device. For this, the slider is mounted on the carriage with the possibility of movement in the transverse movement of the carriage in the direction. The drive of rotation of the yarn feeder and the drive of movement of the slider are made in the form of reversible electric motors. In the process of winding the cord onto the rods, the direction of rotation of the yarn feeder is reversed every one and a half turns, which ensures the winding of the cord on the rods with loops with different direction of turns. 3 ill.

WITH

The invention relates to the production of rubber technical products and intended for the assembly of rubber cord tapes, in particular drive belts.

The gap of the invention is the expansion of the technological capabilities of the device.

In FIG. 1 shows a schematic of the proposed device; figure 2 is the same. view from above; in Fig.Z - rods entwined with a cord.

A device for assembling rubber-cord tapes comprises drive 1 and tension (not shown) figure rolls in the form of sprockets 2 of stars 3 covered by an endless sleeve-roller chain and a carriage A mounted on the lead screw 5 with the help of nut 6 with the possibility of movement in the parallel shaft 7 drive roll 1 direction.

The drive shaft 7 is kinematically coupled to the rotary drive 8 and, via a gear transmission 9, to the lead screw 5. The carriage 4 moves along the guides 10 of the frame 11.

A slider-12 is mounted on the carriage 4 with the possibility of moving in the transverse movement of the carriage 4 in the direction and direction, and equipped with a displacement drive 13 in the form of a reversible electric motor, the drive 13 is connected to the spindle 14. The slider 12 is mounted on the latter by means of the nut 15.

On the slider 12, with the possibility of rotation relative to the axis 7 parallel to the shaft 7, eccentric relative to the latter, the yarn guide 16 is mounted with the rotation drive 17 in the form of a reversible electric motor.

The device has a braked spike rp 18.

The device operates as follows.

Rods 19, which are the reinforcement of the assembled tape, are installed in the bushings of the sleeve-roller chain 2.

The cord 20 from the bobbin 18 is passed through the yarn guide 16 and secured to one of the rods 19. The drives 8, 13 and 17 are turned on. With this, the rods 19 are moved relative to the yarn guide 16, which rotates relative to the parallel 7-axis shaft and simultaneously with the help of the slider 12, it is moved in the transverse movement of the carriage 4 in the direction, ensuring that the cord 20 is wound on the 19-rods with loops in different directions of the turns (Fig. 3). During operation of the device, the direction of rotation of the yarn feeder 16 changes when its axis position is reversed relative to the rods 19 every one and a half turns. At the same time, during the change of position of the axis, the thread guide does not rotate, and its translational movement and the movement of the rods around the circle are interrupted for the time of changing the position of the axis of the guide and half of the revolution. During winding, the cord 20 covers the rods 19 alternately from below to above.

When an odd number of rods are installed on the chain, the loops of the adjacent row of cords will be shifted relative to each other so that two adjacent loops (Fig. 6) covering the same rod (not shown) will have opposite turns.
