The invention relates to equipment for the tire industry and is intended for transfer and docking of rubber-cord material.

The purpose of the invention is to improve the quality of joining strip materials.

Fig, 1 shows a device, top view; in fig. 2 is a view A to ne of FIG. one; in fig. 3 is a view B in FIG. one; in fig. 4 shows the drive mechanism for moving the frame with suction cups of the carriage: in FIG. 5 - docking device in the position of material duplication; in fig. 6 - the same, the original position; in fig. 7 and 8 - structural elements lodgement device docking.

The device comprises a feeding conveyor 1 and a selection conveyor 2, a diagonal cutting machine 3, a mechanism

To turn the strip material in the form of a carriage 5 displaced along the guides 4 from the power cylinder 6. The guides 4 are fixed on racks 7 and 8 mounted on the frame of the diagonal cutting machine 3 and the selection conveyor 2. A mechanism 9 is installed in the left zone of the selection conveyor 2 for joining the lender with the receiving conveyor 10. on which the sealing device 11 is fixed. In the diagonal cutting machine 3 and in the area of the docking mechanism 9, sensors 12 and 13 are installed to monitor the edges of the sheet material 14. Kare Single 5 comprises a housing 15, movably mounted in the guide 4 posredstgom supports 16 and 17. The actuator 6 is rigidly secured to a rack on the carriage 7. 5smontirovana ramXI

18 with Pkkum prizoskzmi 19, which by means of links

20 and 21 are hingedly connected to the housing 15. The seven 20 and 21 are of the same length and are arranged in parallel (they form a carriage 15 and a parallelogram frame 10). The middle; Zena 21 pivotally connects 22 with body 15. Link 20 and

21 and tons 22 form a vertical movement actuator of the carriage 5. The link 20 and 21 are pivotally interconnected by a rod 23. rigidly connected through the rod 24 to the rod of the power cylinder 25 mounted on the housing 15.

The supports 26 of the housing 15 serve as guides for the rod 24.

The docking mechanism 9 has a lower clamp 27, an upper clamp 28 and means for orienting the cord edges in the form of a clamp 29. mounted on a pneumatic cylinder 30. 30. The clamp 28 is rigidly fixed on a double shoulder strap 31, hinged on a platform 32 and connected at one end o A WELL of a power cylinder 33 pivotally mounted also on the platform 32. At the other end, the lever 31 is connected to the upper clamp 28. The platform 32 is mounted on the threaded parts of the shafts 34. kinematically interconnected by a chain transmission 35. The shaft 34 is rotated from the electric motor 36 through the flexible transmission 37. The bearings 38 of the shaft 34 and the engine 36 are fixed on the frame 39. The lower clamp 27 is made in the form of a slide 40, rollers 41, whose axes 42 are spring-loaded and are located in the slots 43 of the slide 40. The springs 44 are also installed in slots 43. The slider 40 is connected to the stem 45 of the power cylinder 46, rigidly connected to the platform 32. The slider 40 is mounted on roller bearings 47. In the extreme positions, the carriage 5 interacts with the dampers 48.

The device works as follows.

After cutting the rubberized cord on the diagonal cutting machine 3, the cord band is conveyed to the carriage 5 by the conveyor 1. Under the action of the pneumatic cylinder 25, the rod 23 rotates the links 20 and 21, which in turn, by means of the pull 22, move the frame 18 vertically downward until the suction pad 19 comes into contact with the stripe of cord 14. After switching on the vacuum, the frame 18 has the stripe of cord 14 rising up. At the same time, the carriage 5 under the action of a strong cylinder b moves to the zone of the conveyor 2, i.e. a measurable 14-lane cord occurs.

conveyor 2 so that the edge of the stripe cord 14 is located on the lower clamp 27 of the mechanism 9 for docking. After vacuum in suckers 19, carriage 5

returns to the starting position.

The required position of the edges of the stripe cord 14 and the coupled tape to be taken away is provided by an automatic adjustment system - sensors 12 and 13,

0 actuating mechanism in the composition of the electric motor 36 and the mechanical transmission 37. 34 and 44, 35.

In the process of orientation of the edges of the cord, its fixed position is provided by pressing 29 (Fig. 6). The cord is duplicated by rolling it with rollers 41 in the position when the cord is clamped between the clamp 28 and the clamp 27, i.e. at the moment of clamping the cord under the action of the power cylinder 33. After the duplication is completed, the coupled cord tape is selected by the conveyor 10 and fed to the device 11 for seaming, with the clamps 28 and 29 in the upper half5. life. By the end of the selection of the joined cord tape by the carriage 5, the next strip of cord 14 is fed to the docking zone, then the docking and selection cycle repeats. When you change the angle close

The cord 0 conveyors 2 and 10 together with the docking device 9 are installed along the pn axis (Fig. 1), i.e. at an angle a.

The cycle of transfer, docking and selection of the cord occurs as described above.
