Description

Technical Field

[0001] The utility model relates to the technical field of tire production, in particular to a spiral unpowered roller conveyor. Background Art

[0002] In tire production workshops, tires are often transported from one process to another via conveyor belts. To save space, conveyor belts of different heights are usually used to transport tires, thereby improving space utilization. Tires are generally transported between conveyor belts of different heights using elevators, but elevators are relatively expensive. Therefore, companies now mostly use spiral slides for unpowered tire transportation to reduce costs. In order for the spiral slide to transport tires of different sizes, the width of the spiral slide needs to be designed based on the size of the largest tire. Therefore, when transporting smaller tires, the tires may run into each other as they slide down the spiral slide. In addition, due to the high sliding speed, when the tire slides out of the spiral slide, it may rush out of the conveyor belt, increasing the workload for the staff. Utility Model Content

[0003] The technical problem to be solved by the present invention is: in order to overcome the shortcomings in the prior art that the tire may collide with each other when sliding down the spiral slide, and the tire may rush out of the conveyor belt when sliding out of the spiral slide at a high sliding speed, the present invention provides a spiral unpowered roller conveyor.

[0004] The technical solution adopted by the utility model to solve its technical problems is: a spiral unpowered roller conveyor, including a column and a spiral slide arranged around the column, the spiral slide including a spirally arranged inner bracket and a spirally arranged outer bracket, a plurality of first rollers are rotatably connected between the inner bracket and the outer bracket, the inner bracket and the outer bracket are both provided with baffles, a plurality of second rollers are rotatably arranged on the baffles, a buffer assembly is provided on the tail side of the spiral slide, the buffer assembly includes a chain plate and a frame, the chain plate is provided between any two adjacent first rollers, a connecting plate is provided on the lower side of the chain plate, fixed rods fixedly connected to the connecting plate are provided at both ends of the chain plate, a cylinder is provided on the frame, and a floating joint is provided between the output end of the cylinder and the connecting plate.

[0005] The upper end of the spiral slide corresponds to the end position of the upper conveyor belt, and the lower end corresponds to the position of the lower conveyor belt; when the tire is transported from the upper conveyor belt to the spiral slide, the tire slides from top to bottom along the first roller, and the baffles on the inner bracket and the outer bracket play a guiding and limiting role on the tire through the second roller; in order to prevent the tire from sliding down too fast, a buffer assembly is set at the tail side of the spiral slide. When the cylinder is extended, the chain plate passes through the gap between the two first rollers to block the tire. After the tire is stopped, the cylinder contracts, the chain plate position drops to below the first roller, and the tire slides slowly to the lower conveyor belt.

[0006] Furthermore, in order to prevent the cylinder output end from bending and deforming, two guide sleeves are provided on both sides of the vertical frame, and a guide column is slidably provided in the guide sleeve. The guide column is parallel to the axis of the cylinder output end, and the upper end of the guide column is fixedly connected to the connecting plate.

[0007] Furthermore, in order to increase the stability of the roller conveyor, it also includes a support assembly, which includes multiple first support plates and multiple second support plates. The multiple first support plates are evenly arranged along the circumference of the column, and one end of the second support plate is fixedly connected to the first support plate, and the other end is against the lower side of the inner bracket and / or the outer bracket.

[0008] Furthermore, in order to increase the stability of the roller conveyor and ensure that the roller conveyor can adapt to the transportation of large tires, a plurality of fixed screws are connected between the inner bracket and the outer bracket, and the height of the fixed screws is lower than the height of the two adjacent first rollers. A reinforced base is provided at the lower end of the column, and a plurality of support frames are connected to the outer bracket.

[0009] Furthermore, in order to increase the stability of the roller conveyor, the second support plate is a trapezoidal plate or a triangular plate, and the angle between the projections of any two adjacent second support plates on the horizontal plane is 45°.

[0010] The beneficial effects of the utility model are as follows: the spiral unpowered roller conveyor provided by the utility model adopts a buffer component arranged at the tail side of the spiral slide to intercept and buffer the sliding tire. After the tire is intercepted, the chain plate on the buffer component exits the spiral slide, and the tire slides smoothly and slowly into the lower conveyor belt through the slope of the tail side of the spiral slide, and the operation is stable and reliable.
