Abstract

FIELD OF THE INVENTION The invention relates to tire industry equipment, namely, an YVCT product for. centering the tape material, which allows to simplify the design of the device and improve the quality of centering. The device includes a guide frame with centering rollers and a conveyor belt. In the frame there are rollers, which are rotatable around a vertical axis, rigidly connected by a four-stage mechanism. The frame is connected to a two-cavity pneumatic cylinder. When the conveyor moves and interacts with the rollers, a lateral force is created that moves the guide frame towards the centering of the material. 3 il.

Description

The invention relates to equipment for the tire industry and is intended to center tape material.

A device for centering the cord is known, comprising a frame mounted on a support, the extreme rollers are mounted on the frame. The frame has rollers and guides with rods connected to the trunnions in which the middle swing roller is mounted. The pins are fixed with rollers, spring-loaded with springs to the direction of Yush. (Copiers), installed with the possibility of adjusting the angle of their inclination. Edge position sensors are mounted on the frame. The frame is connected to the earring, which, in turn, is connected to the pneumatic cylinder rod. The latter is connected with the rod of another pneumatic cylinder. The internal cavities of both pneumatic cylinders are interconnected by a valve.

However, the presence of a middle roller, spring-loaded rollers in contact with guides (copiers), complicates the design of the device and increases its size and weight, with the result that the system is inert, poorly controlled. From the scheme of the mechanism, it follows that when the frame is displaced, for example, to the left of the extreme rollers, the material rushes to the left and from the middle to the right, which leads to a poor quality of centering.

The purpose of the invention is to improve the quality of centering and simplify the design.

The guide frame 1 with the rollers 2 and 3 installed in it and the rod 4 through the bracket 5 is pivotally connected by a finger 6 to a pivoting bracket 7 pivotally mounted on a vertical axis 8 fixed to a transverse frame 9, in turn mounted on frame 10 a guide conveyor 11 on which the tape material 12 is located. The edge of the tape material 12 is in the area of the sensor 13 of its position. In frame 1 there are rollers 14, the supporting forks 15 of which are hinged in frame 1 and rigidly connected to pivoting links 16 and 17, pivotally connected by a pull 18 and installed in hinges 19 and 20 of frame 1, together forming a four-level mechanism.

The continuation of the link 17 is pivotally connected to a pneumatic cylinder 21 having a cavity 22, a piston 23 connected to the link 17, and a cavity 24 to a piston 25 connected pivotally to the cross frame bracket 26 9. The continuation of the link 17 in the extreme positions is limited by adjustable stops 27 and 28

The device works as follows.

When the tape material 12 is displaced from the nominal position, its edge enters the zone of the photo sensor 13. When the beam of the photo sensor 13 crosses the material 12, the signal 12 triggers the actuator of the pneumatic cylinder 21. The position of the piston 23 and the roller 14 is shown at which the guide frame 1 shifted to the right in the course of the movement of the material 12, while the material 12 is also shifted to the right. The movement of the piston 23 causes the rotation of the link 17, which is the driving link in the four-link mechanism (links 16, 17 and 8 ha 18). The link 17 rotates the link 16 through the tug 18. At the same time, the forks 15 and the rollers 14 mounted therein turn. When the conveyor 11 is moved and interacting with the rollers 14 at an angle to the direction of movement of the conveyor 11. a lateral force arises due to which the guide frame 1 moves in the direction of the force vector. In case of stable material movement

12, the roller 14 returns to its original neutral position (Fig. 1). The position I of the piston 23 corresponds to the neutral position of the roller 14, the position II to the right offset of the guide frame 1, the position IV of the piston 25 to the neutral position of the frame 1, the position III of the piston 25 at the position I of the rod 23. to the left shift of the frame 1.

Position II and III of the piston 25 corresponds to the neutral position of the roller 14.

The device provides a smooth and efficient centering of the moving material, has a simple design, does not require a special drive to move the centering elements due to the use of a conveyor belt as a drive.
