Embodiment
The embodiment of the present invention is further described below in conjunction with accompanying drawing.
As shown in figure 1, automatic tread serviser, including tyre surface conveying mechanism, tread cutting device 3, pressure roller 6 and control
System, by tyre surface conveying direction, on the basis of tread cutting device 3, tyre surface conveying mechanism is divided into rear conveying mechanism 1 and preceding conveying
Mechanism 2, front delivery mechanism 2 includes conveyer belt 201.
Automatic tread serviser also includes tyre surface length control device 4, tyre surface deviation correcting device 5, conveying device 2 before being installed in
On, between tread cutting device and pressure roller 6.
As shown in Fig. 2 tyre surface length control device 4 includes fixed length camera device 401, line slideway 402, clamp system, straight line
Guide rail 402 is arranged on mounting bracket 403 parallel to the direction of front delivery mechanism 2, fixed length camera device 401, and mounting bracket 403 is arranged on
On line slideway 402, clamp system connects with mounting bracket 403, including fixed plate 404, clamping plate 405 and clamping cylinder 406, Gu
Fixed board 404 is contacted with the upper surface of conveyer belt 201, and clamping plate is located at the lower section of conveyer belt 201, and clamping cylinder 406 receives control system
Signal, drives clamping plate 405 to move up and down.In work process, according to the difference of tyre surface severing length, tyre surface length control device 4
Position is adjustable.Set tread cutting device 3 needs severing to the distance at the camera center of fixed length camera device 401 as tyre surface
Length.During adjusting position, control system gives the signal of clamping cylinder 406, and clamping cylinder control clamping plate 405 is moved upwards, with
The mating reaction of fixed plate 404, clamping conveying belt 201, so as to drive mounting bracket 403 and fixed length camera device 401 to be led along straight line
Rail 402 is moved.
As shown in figure 3, tyre surface deviation correcting device 5 includes correction camera device 501, adjustable plate 502 and YE 503;
Camera device 501 of rectifying a deviation is arranged on the top of conveyer belt 201, the transmission of adjustable plate 502 and conveyer belt 201 through mounting bracket 505

Moved in the conveying direction of conveyer belt 201.In the course of work, the center of tyre surface needs to overlap with the center conveyor set, ability
Ensure the quality of tyre production.
The image pick-up signal of fixed length camera device 401 and correction camera device 501 is sent to control system.
Wherein, the image that fixed length camera device 401 feeds back needs the length of severing for detecting whether tyre surface has reached.When
The material head of tyre surface, which is moved in the image-capture field of tyre surface length control device 4, to be started, and tyre surface fixed length camera device 401 is persistently to tire
Face is taken pictures, and by image feedback to control system, when shooting center and the tyre surface material head position weight of tyre surface fixed length camera device 401
During conjunction, judging that the position of tyre surface has reached needs the length of severing, and control system starts tread cutting device 3, by tyre surface
Severing.
The image that correction camera device 501 feeds back is used to detect tyre surface during conveying, if tyre surface center is with setting
There is deviation in fixed center.Reference center is set, when there is deviation, the center line that image is fed back will exist with reference center
Deviation, now, YE 503 drive adjustable plate 502 to move, and the transverse shifting of conveyer belt 201 are adjusted, so as to realize conveying
Automatic joint is realized in accurate laminating of the tyre surface on drum, the butt joint pressing after the completion of laminating of pressure roller 6.
