Description

Technical Field

[0001] The invention relates to the technical field of tire building machines, and in particular to a feeding system, a feeding method and a tire building machine. Background Art

[0002] The one-step passenger radial tire molding machine is a mechanical device that places the cylindrical tire blank produced by the first-stage molding machine on the shaping drum of the second-stage molding machine, and then combines it with the components made of the belt layer, cap layer, tread, etc. completed on the bonding drum of the second-stage molding machine. After the tire blank is inflated, pre-shaped, and shaped and rolled, it is made into a green tire before vulcanization.

[0003] The mechanism of the two-stage forming machine is mainly composed of the front and rear conveying templates of the tread and the front and rear conveying templates of the belt layer. The main functions of the two-stage feeder are the conveying, fixed-length cutting and laminating of the tread and belt layer drum. In the existing forming machine, the position of the belt layer drum does not move during laminating. The two belt layer conveying templates slide towards the laminating position of the belt layer drum and are laminated with the belt layer drum. Since the cutting positions of the two belt layer conveying templates are the same, there is a risk of collision. In addition, the sliding cutting will cause the belt layer to slip on the conveyor belt, and there may be a slight deviation in the position of each placement, which greatly affects the accuracy of the belt layer template placement, thereby affecting the laminating quality.

[0004] Therefore, how to avoid the collision between the two belt layer templates while improving the positioning accuracy of the belt layer conveying template, thereby effectively improving the lamination quality and lamination efficiency is a technical problem that technical personnel in this field urgently need to solve.

The first front conveying template 300 and the second front conveying template 500 are both arranged at the lower end of the belt layer drum 200. The rear ends of the first front conveying template 300 and the second front conveying template 500 are respectively rotatably connected to the frame 100, and a lifting device 900 for lifting or lowering the first front conveying template 300 and the second front conveying template 500 is further arranged at the front ends of the first front conveying template 300 and the second front conveying template 500.

[0044] When performing belt layer lamination, the first belt layer is conveyed from the first rear conveying template 400 to the first front conveying template 300, and the second belt layer is conveyed from the second rear conveying template 600 to the second front conveying template 500. The lifting device 900 is started, and the lifting device 900 drives the first front conveying template 300 and the second front conveying template 500 to rise to a preset height. At this time, the belt layer drum 200 is run to the first belt layer lamination station to perform the lamination of the first belt layer. After the lamination is completed, the belt layer drum 200 is run to the second belt layer lamination station to perform the lamination of the second belt layer. Compared with the prior art, since the belt layer drum 200 can be horizontally moved to two different belt layer lamination stations for belt layer lamination, the occurrence of the collision phenomenon caused by the two front conveying templates sharing one lamination station is avoided. Moreover, the first front conveying template 300 and the second front conveying template 500 only perform lifting movements and do not perform horizontal movements, so the risk of slipping during sliding lamination is avoided, thereby effectively improving the accuracy of the belt layer conveying template in place and greatly improving the lamination quality and lamination efficiency.

[0048] Please refer to Figure 1 , the feeding system disclosed in the embodiment of the present invention further includes a front tread conveying template 700 and a rear tread conveying template 800 for conveying the tread. The front tread conveying template 700 is arranged at the upper end of the belt drum 200. The rear end of the front tread conveying template 700 is rotatably connected to the frame 100. A tread template lifting mechanism is further arranged at the front end of the front tread conveying template 700. When the tread is being adhered, the tread is conveyed from the rear tread conveying template 800 to the front tread conveying template 700, the belt drum 200 is run to the third adhering station, the tread template lifting mechanism is started, and the tread template lifting mechanism drives the front tread conveying template 700 to descend to the third preset position for tread adhering. Since the belt drum 200 only moves horizontally and does not move vertically, the positioning accuracy of the belt drum 200 is further improved, the cycle time is reduced, and the adhering efficiency is increased.

[0049] It should be noted that the front tread conveying template 700 is connected to the frame 100 through a rotating shaft. In order to ensure the flexibility of the swing of the front tread conveying template 700, the front tread conveying template 700 in the embodiment of the present invention is connected to a bearing through a rotating shaft, and the bearing is fixed to the frame 100 through a connecting plate to realize the swing constraint of the front tread conveying template 700.

[0050] It should be explained that the front end of the front tread conveying template 700 refers to the position close to the belt drum 200, and the rear end of the front tread conveying template 700 refers to the position far from the belt drum 200.

[0051] It should be further explained that a separate control button can be set to control the belt drum 200, the first front conveying template 300, the first rear conveying template 400, the second front conveying template 500, the second rear conveying template 600, the front tread conveying template 700, the rear tread conveying template 800 and the lifting device 900.

Therefore, through the cooperation of the second guide rail and the second slider 9031, the lifting device 900 can move on the second front conveying template 500 to adjust the position of the lifting device 900 on the second front conveying template 500.

[0057] Specifically, the second slider 9031 and the second connecting block 9032 are connected by a rotating shaft. Therefore, the second slider 9031 can drive the second front conveying template 500 to swing along the axial direction of the rotating shaft to adjust the swing angle of the second front conveying template 500.

[0058] It should be noted that two first connecting devices 902 and two second connecting devices 903 are respectively provided and are respectively disposed on both sides of the first front conveying template 300 and the second front conveying template 500.

[0070] Since this tire building machine adopts the feeding system disclosed in the above - mentioned embodiment, this tire building machine has the technical advantages of the above - mentioned feeding system, and the embodiment of the present invention does not elaborate on this.

[0071] Please refer to Figure 6 , the embodiment of the present invention also discloses a feeding method, including: S100: Controlling the belt layer drum to run to the first laminating station, controlling the first front conveying template to rise to the first preset position for laminating the first belt layer; S200: Controlling the belt layer drum to run to the second laminating station, controlling the second front conveying template to rise to the second preset position for laminating the second belt layer; S300: Controlling the belt layer drum to run to the third laminating station, controlling the front conveying template of the tread to descend to the third preset position for laminating the tread.

After the lamination is completed, the belt layer drum 200 is run to the second belt layer lamination station to perform the lamination of the second belt layer. Compared with the prior art, since the belt layer drum 200 can be horizontally moved to two different belt layer lamination stations for belt layer lamination, the occurrence of the collision phenomenon caused by two front conveying templates sharing one lamination station is avoided. Moreover, the first front conveying template 300 and the second front conveying template 500 only perform lifting motion and do not perform horizontal motion, so the risk of slipping during sliding lamination is avoided, thereby effectively improving the accuracy of the belt layer conveying template in place and greatly improving the lamination quality and efficiency.

[0073] The embodiment of the present invention further includes S300: controlling the belt layer drum 200 to run to the third lamination station, controlling the front tread conveying template 700 to descend to the third preset position to perform the lamination of the tread. When the belt layer drum 200 finishes laminating the belt layer, it runs to the third lamination station again to perform the lamination of the tread. Since the belt layer drum only moves in the horizontal direction and does not move in the vertical direction, the positioning accuracy of the belt layer drum 200 is further improved and the cycle time is reduced.
