PL96031B1 - MACHINE FOR FITTING LARGE TIRES - Google Patents

Description

The subject of the invention is a device for converting large tire selection.

Currently, large-size tires are ready-made are important from multilayers prepared during the period before the packaging of tires. Multilayers 5 it is built on a device consisting of a bark pusu - base, pressure roller of the fixed drum cooperating with a roller with adjustable stroke allowing you to set the inner length the circumference of the foldable tire. Two or four positions- 10 The rack is used to supply the device with rubber valid cord.

A group of equipment for packing tires jiest type presented in the publication entitled: "Avto- mobilnyje shiny "- collective work 1963 15 The set of devices according to the invention consists of from a container built of a movable base na¬ driven by a geared motor adapted to the weir front - back and guides. Total travel the tank is limited by the tap switch built into the guides. Rotating tower the container is adapted to rotate left - right to the vertical axis, which makes it possible to taking a given layer of cord wound on the shaft drug and free access to individual fights with cut layers of cord of appropriate quality measures. The roller table is used to load one partial tread belt.

The subject of the invention is illustrated in, for example, the embodiment in the drawing in which fig. 1 30 shows the device in a side view, and Fig. 2 - top view.

The tire confection machine consists of bits spolu of rollers 1, which include the subassembly mechanically operated upper and lower rollers no, for smoothing overlaid layers cord and pressing them down to bring them together sticking. Confectioning machine body 2 with na¬ the pedal and the brake and the switching button 12 is used to rotate the shaft 13 of the drive driven by a motor through a belt-toothed gear no and stopped with an air brake.

An automatic main is mounted on the shaft 13 confectioning drum 3 and auxiliary drums 4 and 4a pivotally mounted in a tailstock assembly 6 which translates it is shifted by actuators 9 and is used for positioning the entire cord width of the harnessed tire and up to connecting the cord into a closed circuit.

Sliding tailstock assembly 6 placed on the plate the cut 5 is used to support shaft 13 and to turn t-sliding auxiliary attachment of the drum on 4a. Hopper guides 7 are perpendicular by moving the cassette into the correct position nika 8 with cut layers of wound cord for fights 18 in relation to the shaft axis 13. Container 8 it is driven by a geared motor for forward-backward driving, operated by button 10 is used for hanging 18 rollers with cut cord.

The total travel of the hopper 8 is limited switch 19 built into the guides 7. 96 0313 96 031 4 The discs of the permanent magnet 11 are held in place placing the first layer of cord on a steel, smooth the surface of the drums pushed together.

4 rings centering the bead core 15 placed in the auxiliary drums 4 and 4a are used for punching finger joints and sticking them to tailor-made tire bead on the main drum 3.

The centering rings 14 are actuated by an actuator 9 powered by compressed air controlled by pneumatic valve 16. Roller table 17 serves for pulling the simultaneous tread belt in the C or putting it on the last layer of confectioning valid tire.

Through the pneumatic valve 16 is supplied compressed air for actuators 9, which slide the auxiliary drums 4 and 4a towards the car matte main confection drum 3.

Button 10 switches on the gear motor which moves the hopper 8 towards the packaging machine nej 3. From the battle 18 of the container 8 unfolds first cover or rubberized cord layer and puts on top drum 3, 4 and 4a. At the edge of the cord the discs of the permanent magnet 11 are put on and trimmed the foot 12 engages the engine of the machine 2. After winding the first layer of bark a lot of the desired angle of the threads and width, the remaining layers of cord are wound up, which are unfolded 18 resources located on individual battles nika8. , The centering rings 14 move securely in advance of the auxiliary drums new moon 4 and 4a. After winding the desired number of layers, the Pressing 10 returns the tray to the off position waiting. The pneumatic valve 16 moves back auxiliary drums 4 and 4a to the position of the exit wego. A set of rollers 1 driven pneumatically not and mechanically shaped on the head 3 layers of cord are drummed, breaking them into a tear shaft axis. 13. From the interior of the auxiliary drums new moon 4 and 4a are placed on centering rings 14 previously moved wire rings 15. Za- the pneumatic valve 16 moves the auxiliary Junctions 4 and 4a with centering rings 14 and the wire rings 15 towards the main drum 3.

Strong pneumatic pressure sticks the rings wire 15 for the front surface of the confectionery valid tire. Then the auxiliary withdraws drums 4 and 4a and curls up on wire rings dangling ends of the layers of cord and roll from the table kowy pulls the simultaneous tread belt wrapping the circumference of the assembled tire.

After the tire is assembled, the drum of the head is folded down ny 3 and tailstock assembly 6 retracts ready tire. Then it translates set of wire rings 15 outside rings centering point 14 and with the main drum folded in 3 prepares the device for the next cycle work.

Claims (1)

1. Patent claim A device for assembling large size tires, characterized by the fact that it has a reservoir (8) made of a movable base, driven by a gear motor 30 adapted to drive forward-backward, from a rotating tower adapted to left-right rotation with respect to the vertical axis enabling the selection of a given layer cord wound on the rollers (18) and easy access to the individual rolls with cut layers of cord, and a roller table (17) for inserting a simultaneous conveyor belt.
