Example one

The embodiment provides a tire production line, which comprises a plurality of molding machines, a plurality of vulcanizing machines and a tire blank conveying device, wherein the tire blank conveying device is used for conveying the tire blank 20 output by the molding machines and supplying the tire blank to the vulcanizing machines so that the vulcanizing machines can carry out vulcanization treatment on the tire blank 20.

As shown in fig. 1 and 2, the tire blank transfer device comprises two handling mechanisms 1 and a transfer mechanism, which comprises two first transfer sections 2 and a second transfer section 3. The handling device 1 can grip the green tire 20 from the molding machine side and transport it onto the first transport section 2. The second conveying sections 3 are respectively butted with one ends of the two first conveying sections 2. The number of the transport mechanisms 1 corresponds to the number of the first transport sections 2, and each transport mechanism 1 corresponds to each first transport section 2 one by one, so that each transport mechanism 1 can provide a tire blank 20 to each first transport section 2.

By means of the structure, the tire releasing operation processes of the conveying mechanisms 1 are mutually independent because the conveying mechanisms 1 correspond to the first conveying sections 2 one by one, and the condition that the tire releasing operation can be executed only when other conveying mechanisms 1 finish the tire releasing operation does not exist.

Taking 4-6 building machines to form the tire blanks 20 as an example, in the present embodiment, two conveying mechanisms 1 are used to cooperate with two first conveying sections 2 to perform the tire discharging task, wherein each conveying mechanism 1 is responsible for taking out the tire blanks 20 output by 2-3 building machines and correspondingly placing the tire blanks 20 on one first conveying section 2 cooperating therewith, and then the tire blanks 20 can be conveyed to the side of the vulcanizer through the first conveying section 2 and the second conveying section 3.

To maintain the shape of the green tire 20, a tray 10 for carrying the green tire 20 is placed on the first conveying section 2 and the second conveying section 3. Specifically, the pallet 10 can be unidirectionally conveyed with the first conveying section 2 and the second conveying section 3 from the molding machine side to the vulcanizing machine side. That is, the empty pallets 10 can be placed one by one on the first conveying section 2 by a manual or automatic pallet separating mechanism on the molding machine side, after the tire blank 20 is placed on the pallet 10 by the conveying mechanism 1, the pallet 10 carrying the tire blank 20 is conveyed to the vulcanizing machine side along with the first conveying section 2 and the second conveying section 3, and after the tire blank 20 in the pallet 10 is removed, the empty pallets 10 can be collected by a manual or automatic pallet collecting mechanism for further use by being conveyed to the molding machine side. Further, the first conveying section 2 and the second conveying section 3 are arranged at a right angle.

Preferably, in the embodiment, each conveying mechanism can circularly convey the tray 10, so that the empty tray 10 conveyed to the vulcanizer side automatically flows back to the forming machine side to receive new tire blanks to be conveyed, and the conveying efficiency of the tire blanks is improved. Specifically, the first conveying section 2 can convey the tray 10 bidirectionally between the carrying mechanism 1 and the second conveying section 3, and the second conveying section 3 can also convey the tray 10 bidirectionally, so that the conveying mechanism can convey the tray 10 circularly.

Referring to fig. 2, each first conveying section 2 includes a first conveying portion 21 and a first backflow portion 22, the first conveying portion 21 and the first backflow portion 22 extend between the second conveying section 3 and the conveying mechanism 1, and the first conveying portion 21 and the first backflow portion 22 convey the tray 10 in opposite directions. Referring to fig. 3, the second conveying section 3 includes a second conveying portion 31 and a second backflow portion 32, the second conveying portion 31 and the second backflow portion 32 both extend between the first conveying section 3 and the vulcanizer, and the second conveying portion 31 and the second backflow portion 32 convey the tray 10 in opposite directions.

Referring to fig. 1 and 3, the conveying direction of each first conveying portion 21 is rightward in fig. 1 and inward in the vertical plane of fig. 3 to butt against the second conveying portion 31 conveying downward in fig. 1 and rightward in fig. 3 to transfer the tray 10 carrying the tire blank 20, and the conveying direction of each first returning portion 22 is leftward in fig. 1 and outward in the vertical plane of fig. 3 to butt against the second returning portion 32 conveying upward in fig. 1 (not shown) and leftward in fig. 3 to transfer the empty tray 10.

In order to reduce the floor space, in the present embodiment, the first conveying part 21 and the first backflow part 22 are preferably stacked one above the other, and as shown in fig. 2, the first conveying part 21 may be disposed above the first backflow part 22 with the ends thereof being substantially flush. Similarly, as shown in fig. 3, the second conveying section 31 may be provided above the second recirculation section 32.

To join the first return portion 22 and the first conveying portion 21, so that the trays 10 on the first return portion 22 flow onto the first conveying portion 21 again, in the present embodiment, each first conveying section 2 further includes a transfer portion 23, and the transfer portion 23 is configured to transfer the trays 10 between the first conveying portion 21 and the first return portion 22.

Preferably, in the present embodiment, the transfer unit 23 is a lifter, and the lifting end 231 of the lifter is provided at one end of the first conveying unit 21 and the first circulating unit 22 close to the molding machine, so that the lifting end 231 of the lifter can be abutted against the first conveying unit 21 and the first circulating unit 22, respectively, after being lifted and lowered, to transfer the tray 10. It will be appreciated that the lift end 231 of the elevator may deliver the pallet 10 bi-directionally.

Meanwhile, in the present embodiment, each first conveying section 2 further includes an abutting portion 24 for abutting and transferring the tire blank 20 with the conveying mechanism 1, and the abutting portion 24 abuts with the first backflow portion 22 to receive the empty tray 10 output from the first backflow portion 22 when the abutting portion 24 is operated in the forward direction, allow the conveying mechanism 1 to place the tire blank 20 in the tray 10 thereon, and output the tray 10 loaded with the tire blank 20 when the abutting portion 24 is operated in the reverse direction, so that the transfer portion 23 transfers the tray 10 loaded with the tire blank 20 to the first conveying portion 21.

Specifically, as shown in fig. 2, the docking portion 24 may be disposed at one end of the first reflow portion 22 close to the conveying mechanism 1 and between the elevator and the conveying mechanism 1. When the hoist is in the lowered position, the lifting end 231 of the hoist engages the docking portion 24 and the first return portion 22 to dock with the first return portion 22 and receive the empty pallet 10 output by the first return portion 22; subsequently, the lifting end 231 of the lifter conveys the tray 10 to the docking portion 24, and after the tire blank 20 is placed in the tray 10 on the docking portion 24 by the carrying mechanism 1, the docking portion 24 conveys the tray 10 back to the lifting end 231 of the lifter; then, the lifting end 231 of the lifter is lifted to abut against the first conveying unit 21, and the pallet 10 with the green tire 20 thereon is discharged onto the first conveying unit 21, thereby completing the tire abutment operation.

During the interim period when the transfer mechanism 1 returns to the molding machine to pick up the tire, the lifting end 231 of the elevator may fall back to the lowered position to receive the empty pallet 10 again and output the empty pallet 10 to the docking portion 24 for receiving the next tire blank 20 in time, so that the transfer mechanism 1 does not need to wait for the pallet 10.

Of course, the docking portion 24 may also be docked with the first conveying portion 21, for example, it may be disposed at one end of the first conveying portion 21 close to the conveying mechanism 1, and after the first returning portion 22 transfers the empty pallet 10 to the first conveying portion 21, the lifting end 231 of the lifter conveys the empty pallet 10 to the docking portion 24 to receive the tire blank 20, and finally the docking portion 24 and the lifting end 231 of the lifter reversely output the pallet 10 with the tire blank 20 onto the first conveying portion 21 to complete the tire docking operation.

In order to facilitate the transfer of the green tire 20 to the first transfer section 2 by the transfer mechanism 1, the butting portion 24 is preferably located outside the first returning portion 22 or outside the first transfer portion 21, so that the butting portion 24 is not blocked from above and the transfer path of the transfer mechanism 1 does not interfere with the first transfer portion 21 or the first returning portion 22.

In the present embodiment, the first conveying unit 21, the first reflow unit 22, the second conveying unit 31, the second reflow unit 32, the docking unit 24, the lifting end 231 of the lifter, and other structures for conveying the tray 10 may be any known conveying structure such as a single conveying belt or a double conveying belt constituting a double-side bridge structure, and are not limited thereto. The handling mechanism 1 may be an EMS trolley or other spreader, but is not limited thereto. The bidirectional operation of the lifting end 231 and the docking portion 24 of the elevator can be realized by the forward and reverse actions of the driver such as the motor for driving the conveyor belt, which will not be described herein.
