When the second photoelectric detection component 12-2 is triggered in the process of conveying the whole stack of tires along the second conveying component conveying belt 12-3, the second conveying component conveying motor 12-4 stops running;

the clamping cylinder 14-5 drives the clamping connecting rod 14-6 to extend forwards, and the other end of the clamping connecting rod 14-6 drives the joint bearing 14-3 to rotate so as to drive the vertical guide pillar 14-2 to rotate along the vertical central axis of the vertical guide pillar;

While the lifting transmission assembly 15 is carrying the clamping assembly 14, the lifting servo motor 15-5 drives the clamping assembly 14 or the clamping assembly 14 drives the tires together to lift vertically to complete clamping and releasing of the whole stack of tires and pushing of the single tire.

Specifically, after the whole stack of tires is stopped on the second conveying assembly conveying belt 12-3, four groups of holding columns 14-0 of the clamping assembly 14 clamp the tires along the circumferential two sides, at the moment, a lifting servo motor 15-5 drives a lifting chain wheel 15-8 to rotate so as to drive a lifting chain 15-9 to run along the vertical direction, and a lifting slide seat 15-10 vertically lifts along a lifting guide rail 15-6 through a lifting slide block 15-1, so that the clamping assembly 14 and the tires are finally driven, or the clamping assembly 14 is independently driven to lift along the vertical direction.

The control sequence for the operation of the gripping assembly 14 and the lifting and lowering drive assembly 15 can be determined according to the specific process content of the conveying method described herein, and there is no unique, definite order limitation.

As shown in fig. 6 and 7, the tire pushing assembly 13 includes a tire pushing slide rail 13-0 mounted on the frame 12-1, and the tire pushing slide rail 13-0 extends forward to the central frame body 10 to extend the unstacked single tire forward from the second conveying assembly 12 to the central frame body 10.

Based on the structural design of the motorcycle tire final assembly equipment, the application simultaneously provides the following motorcycle tire final assembly method, which comprises the following process stages:

stage one, unstacking and conveying

The whole stack of the motorcycle tires is conveyed to the second conveying assembly 12 from the belt conveyor of the first conveying assembly 11, the whole stack of the motorcycle tires is arranged on the second conveying assembly 12, the clamping assembly 14 clamps other tires except the tire at the bottommost layer in the whole stack of the motorcycle tires along the circumferential direction, and the tires are driven by the lifting transmission assembly 15 to vertically ascend;

The storage bin 22 is arranged on the bottom plate 21, and the inner support members 20 which are arranged in a queue in sequence are stored in the storage bin 22;

stage three, placing the inner support piece

On the central frame body 10, the inner support piece placing device places the inner support piece 20 inside the tire body of the unstacked single motorcycle tire;

stage four, tyre unloading

The motorcycle tires with the inner support members 20 inside are transferred one by the tire transfer assembly 40 to the tire unloading conveyor assembly 50 for restacking, and finally the whole stack of motorcycle tires after the final assembly production is removed from the final assembly equipment.

In the unstacking and conveying process, the method specifically comprises the following steps:

step 1, conveying a whole stack of motorcycle tires on a belt conveyor of a first conveying assembly 11, and when triggering and generating a signal of a first photoelectric detection assembly 11-1, starting to operate a second conveying assembly 12 to receive the conveyed whole stack of motorcycle tires;

step 2, the whole pile of tires is continuously conveyed forwards along the second conveying assembly 12, and when a signal of the second photoelectric detection assembly 12-2 is triggered and generated, the conveying component of the second conveying assembly 12 stops running;

step 3, the clamping assembly 14 clamps other tires except the tire at the bottommost layer in the whole stack of tires along the circumferential direction, and the tires are driven by the lifting transmission assembly 15 to vertically ascend;

step 4, the tire pushing assembly 13 pushes the tire positioned at the bottommost layer forward to the central frame body 10 until the tire is blocked and limited by the positioning column 10-2, and the tire pushing assembly 13 returns to the second conveying assembly 12;

step 5, the clamping assembly 14 clamps the rest tires and descends along the vertical direction under the driving of the lifting transmission assembly 15 so as to place the rest tires on the second conveying assembly 12 again, and the clamping assembly 14 resets and releases the tires;

the steps 3 to 5 are repeatedly and circularly executed until all the tires of the pile are sequentially pushed onto the center frame 10.

Thereby completing the technological processes of conveying, positioning, unstacking and pushing the whole piled motorcycle tyre.

Further, in the step 3, the clamping cylinder 14-5 drives the clamping connecting rod 14-6 to extend forwards, and the other end of the clamping connecting rod 14-6 drives the knuckle bearing 14-3 to rotate so as to drive the vertical guide pillar 14-2 to rotate along the vertical central axis of the vertical guide pillar;

the holding column 14-0 is driven by the guide rod 14-1 to clamp the whole stack of motorcycle tires along the two sides of the circumference;

centering of the tire on the second conveyor assembly belt 12-3 is accomplished by the interaction of the four sets of depending posts 14-0 with the tire.

Further, in the step 5, the process opposite to the step 3 is that the clamping cylinder 14-5 drives the clamping connecting rod 14-6 to retract backwards, so that the components are sequentially reset in a transmission manner, and finally the holding column 14-0 is reset in a swinging manner along the two sides in the circumferential direction to be separated from the motorcycle tire.

Further, in the above steps 3 and 5, the lifting servo motor 15-5 drives the lifting chain wheel 15-8 to rotate so as to drive the lifting chain 15-9 to move vertically, and the lifting slide 15-10 is lifted vertically along the lifting guide rail 15-6 through the lifting slide 15-1, so as to finally drive the clamping assembly 14 and the tire or independently drive the clamping assembly 14 to lift vertically.

Further, in the step 4, in the process of pushing the unstacked single tire, under the influence of the acting force of the tire, the push rod 13-3 swings around the pushing rotating shaft 13-5 at the bottom to be erected upwards along the groove 13-6 and is stopped at the tail end of the groove 13-6, and the pushing plate 13-7 in a vertical state provides the pushing force for forward conveying of the tire;

further, the rodless cylinder 13-1 drives the sliding seat 13-2 to retreat, and the push plate 13-7 is pushed to be separated from the previous tire 1;

the pushing spring 13-4 retracts due to the elasticity of the pushing spring, and the push rod 13-3 swings downwards along the groove 13-6 to be in a free state;

when the push rod 13-3 touches the following tire 2 on the second conveying assembly 12 in the retraction process of the sliding seat 13-2, the push rod 13-3 continuously swings downwards along the groove 13-6 under the action of the downward pressure of the following tire 2, and meanwhile, transmits the pressure to the push spring 13-4 to compress the push spring 13-4;

when the push rod 13-3 retreats to the rear part of the following tire 2 along with the sliding seat 13-2, the push rod 13-3 swings upwards along the groove 13-6 to erect under the action of the self elastic force of the push spring 13-4 so as to prepare for the next pushing process.

During the feeding process of the inner support members, the inner support members 20 are stored and arranged in a queue in the storage bin 22;

when the inner support members 20 at the front end of the row are removed, the vertical ends of the inner support member pushing plates 23-2 push the row of the inner support members 20 forward from the rear under the action of the longitudinal pushing force continuously provided by the inner support member pushing cylinders 23, so that the front end of the row of the inner support members 20 always abuts against the inner support pressing plate 24 until all the inner support members 20 in the row are removed one by one.

Further, when the opposite photoelectric detection component 25 triggers a signal, the triggering signal is fed back to the control system to perform an alarm form such as acoustoelectric alarm, etc., so as to prompt manual intervention and supplement the inner support 20 into the stock bin 22.

When the inner support members 20 of different specifications need to be replaced, the hand wheel 26 on the connecting rod 26-2 is rotated to realize transmission sequentially through the first transmission gear 26-3, the central transmission gear set 28, the second transmission gear 29-2, the third transmission gear 29-3 and the fourth transmission gear 29-4, so that the screw rod 29-5 is driven to rotate clockwise or anticlockwise, the screw rod 29-5 drives the connecting seat 29 to horizontally move along the guide shaft 29-6 through the screw nut 29-7, and the horizontal movement of the connecting seat 29 directly changes the transverse width of the storage bin 22.

Further, a bin adjustment scale 27 is disposed on a side of the bin 22, and the width of the currently adjusted bin 22 can be conveniently and directly determined by the bin adjustment scale 27.
