Abstract

The invention relates to equipment for assembling tires for pneumatic tires. The purpose of the invention is to increase the productivity of the device when applying a strip material to a non-rotating assembly drum. For this, the mechanism for applying a strip material to the drum is made in the form of a body with an axis 10 installed in it and levers 11, 12 mounted on the latter. The freely rotating rollers 8, 9 are mounted on the free ends of the levers 12, 11. The mechanism for feeding the strip material is made in the form of a roller table 2 mounted on a slider (P) 1 with cantilever rollers 3 and a drive 4 for moving P1 in a vertical plane. The case is installed on P1. Freely rotating rollers 8, 9 are spring-loaded springs 14, 13 and are installed in the same plane with rollers 3 of roller table 2. Roller 15 of roller table 2 is located on the vertical axis of symmetry of drum 7, mounted below working surface of roller table 2. Drive 4 of mechanism for applying strip material is mounted on slider. 2 hp ff, 11 ill.

The invention relates to equipment for assembling tires for pneumatic tires, can be used in tire procuring, in particular, when applying a bicycle cycle layer to an assembly drum when assembling bicycle tires.

The purpose of the invention is to improve the performance of the device when applying a strip material to a neurash assembly drum.

FIG. 1 shows a general view of the device; in fig. 2 - the same in terms of; on 4) ig. 3 is a view A of FIG. 2; in fig. 4 - a device with a measured dimensional blank, general view; in fig. 5 - a device with rollers brought to the drum, general view; FIGS. 6, 7 illustrate the process of superimposing the branches of the cycle medium on the assembly drum; in fig. 8-11. What is the overlay of cycling on the assembly drum?

A device for applying a strip material to an assembly drum contains a mechanism for feeding a strip material, impregnated in the form of a roller table 2 installed on a slider 1 with cantilever rollers 3 and a drive 4 for shifting the slider 1 in a vertical plane. On the slider 1 is installed housing 5.

The device contains a directing mechanism 6. an assembly drum 7 and a mechanism e. 1I applying a strip material to the drum 7 with freely rotating rollers 8 and 9, which is made in the form of a housing 5 with axis 10 installed in it and levers 11, 12 mounted on axis 10 Freely rotating rollers 8 and 9 are mounted on the free ends of levers 11 and 12, spring loaded by spring 13, 14 and mounted in the same plane with rollers 3 of roller table 2. Roller 15 of roller table 2, located on the vertical axis of symmetry of the drum 7, is mounted below working rho surface anga 2. The drive mechanism for imposing a strip material is made in the form of pneumatic cylinders 16 and 17, rails 18, 19 HjecTepeH 20, 21 and guides 22 and mounted on a slider 1. The slider 1 is mixed in the guide rollers 23 mounted on racks 24 base 25. Cycle cycle layer 26 (FIG. 8) is supplied by feed device 27 through transporting mechanism 28 to assembly drum 7. Record mechanism 6 cuts cycle layers 26 on order 1.

The device works as follows.

A cycle layer 26 is transported by the feed mechanism 27 by the feed device 27 to the zone of the non-rotating assembly drum 7. A cut is made by the mechanism 6 to obtain a dimensional blank 29. The device is ready to work. Then, the actuator 4 (FIG. 9) will move the slide 1 vertically upwards until the rollers 8, 9 come into contact with the drum 7. At the same

At the same time, the roller table 2 will also move upward until the roller 15 is in contact with the drum 7. Thus, the bicycle stress layer is sandwiched between the assembly drum 7 and rollers 8 and 9, the levers 11, 12 and roller 15 of the roller table 2. At the same time, the feed device 27 moves down (Fig. 9). Next, the pneumatic cylinder 17 moves the rail 19, thereby driving the lever 11, which is driven by the roller 9, rolling on the assembly drum 7, imposes one branch 30 of the bicycle frame 29. The end is fixed on the assembly drum 7. Then the rail 19 is retracted by the pneumatic cylinder 17 to the initial position, and the lever 11 also returns to the lower position of the initial one. The branch of the bicycle cycle layer remains on the assembly drum 7 (Fig. 6). At the same time, the feed device 27 is stirred for the thrust mechanism 6 (Fig. 10). Then the pneumatic cylinder 16 mixes the rail 18 to the extreme upper position, driving the gear 12 through the lever 20, which, rolling back along the assembly drum 7, imposes another branch 31 of the layer 29 onto the drum 7. The branches join and roll the roller 8 (Fig. 7). At the same time, the feeder moves upwards (Fig. 11) before contact with the cycle medium. The rail 18 is then retracted by the pneumatic cylinder 16 to the lowest position. The lever 12 returns to its original position, and with the fivodom 4 the slider I and the live rolls 2 move to the lowest position the original. Then the cycle repeats.
