Description

The invention relates to devices for applying layers of cord to a drum of an assembly machine and can be used in tire industry, in particular, in the manufacture of carcasses for pneumatic tires and bracelets.

A device for imposing a tape material on an assembly machine drum is known, comprising a lifting mechanism and a carriage mounted on a frame, equipped with a movable table, pressure and guide rollers, an electric blade and a pressure bar. However, such a device does not allow adjustment of the cutting angle.

The purpose of the invention is to create a device that enables adjustment of the cutting angle.

The goal is achieved by the fact that the clamping bar is hingedly loaded with a lifting mechanism by means of screws that contain screws that interact with the common nut, one of which is hinged to

clamping plate, and the other - with a lifting mechanism.

Figure 1 shows the proposed device; figure 2 - section aa of figure 1; on fig.Z - type B of FIG. 1; figure 4 - section bb In figure 3.

The device for applying tape material to the drum of the assembly machine comprises a bed 1 on which the guides 2 are mounted, and a carriage 3 movable thereon, including under the hinged plate 4, on which the front pillar 5 is installed with a pinch roller 6 and an electro-blade 7 and a back a stand 8 with a guide roller 9 and a movably mounted table 10,

Vacuum suckers 1I are located along the edge of the movable table 10. On the base 1, an L-shaped stand 2 with a pneumatic cylinder 13 and drive rollers 14 is installed to drive the drum 15 of the assembly machine.

On the lift no. 1 of the mechanism 16, pasHei on the frame, using a screw stud 17, a hinge 18 is mounted, each clamp 17 consists of interacting with a common nut 19 screw 20, one end of which is connected with clamp strap 18, and a screw 21, at one end pivotally connected to the lifting mechanism 16, the Nuts 19 have right and left cuts. There are nuts 22 and 2 for fixing. The device works as follows. Before the start of operation, the tape material 24 is led through the guiding pin 9 under the clamping bar 18, and when the latter is lowered it is caught by the suction cups 11. After the bar is raised, the suction cups remain engaged. The carriage 3 is guided along the guides 2 under the center of the drum 15, the Table 10 rises, presses the material to the drum 15, upon further movement of the carriage 3 of the drum 15 is rotated and winds up a layer of material. At the end of the carriage stroke, the command to lower the table and return carriage to its original position. After the carriage returns to its original position, the drum rotates through the drive rollers 14 supplied by the pneumatic cylinder 13 and the material is further applied. The drum is rotated 3/4 of a turn. Then the presser bar 18 is lowered, the vacuum suction grips the belt, the blade 7 is cut, and the remainder of the material is superimposed on it by turning the drum 1.5. The bar is raised, and then the cycle is repeated. Adjusting the cutting angle and reconfiguring the device to a new angle is carried out by turning the plate 4 with the rear support 8 and table 10 installed on it and rotating the nut 19. And by interacting the nut f9 s. Screws 20 and 21 vary the length of the screw fastener 17, Since the latter is associated with the clamping clamp. , the strap and with the lifting mechanism, the position of the clamping strap is changed, which allows you to adjust or change the angle of the cut. The proposed device provides a quick reconfiguration of the cut angle, which reduces unproductive time, / / / 24 / / 10 ff
