Description

Technical Field

[0001] The utility model belongs to the technical field of hanging systems and relates to a hanging conveyor line elbow component and a hanging conveyor line. Background Art

[0002] The hanging system is used in clothing and home textile production enterprises. It includes a ring track. Several workstations are arranged at intervals along the direction of the ring track. There is a workstation under each workstation. The garment pieces hung on the hanger are controlled by the system to be transported to the designated workstation for processing through the ring track. After processing, they enter the ring track from the exit mechanism of the workstation and are sent to the next workstation for processing in the next process.

[0003] The common ring rail is a circular metal rail, and the rail at the end needs to be bent into a U shape. The top of the ring rail is generally driven by a chain to drive the hanger on the ring rail to move forward. As a transmission part, the chain has problems such as the need to be tensioned and troublesome installation. Later, a rack-driven structure appeared, and the end elbow of the hanging system adopted a structure spliced ​​with elbow blocks. For example, CN201620629359.X discloses a "main rail elbow", including a roughly C-shaped elbow body, which has an upper open end and a lower open end; the projections of the horizontal planes of the two sides of the elbow body have an angle. The main rail elbow can be designed to different angles, and a combination of elbows at different angles is used to facilitate the realization of directional turning at different angles of the conveyor line track, with strong adaptability and simple assembly.

[0004] CN202020855256.1 discloses "a hanging conveyor line elbow splicing block and a hanging conveyor line". The conveyor line elbow splicing block is C-shaped, the upper end of the elbow splicing block is provided with a rack slide groove opening downward, and the lower end is provided with a hanger rail; a support plate is provided at the lower end of the elbow splicing block, located below the hanger rail, and a slot is formed between the support plate and the lower surface of the elbow splicing block, and the opening direction of the slot is opposite to the opening direction of the elbow splicing block.

[0005] The above elbows are all used for rack-driven conveyor lines, but the hanger rails of the above two elbows are circular. The hangers move on the circular rails, and due to lack of support, they shake greatly, especially at the end elbows. Due to the centripetal force, the hangers often tilt and derail from the elbows. Summary of the invention

[0006] The utility model provides an elbow assembly, which can limit the roller of a clothes hanger both up and down by cooperating with a limiting protrusion and a protection strip, so as to prevent the clothes hanger from derailing when it is bent.

[0007] The elbow assembly provided by the utility model is formed by splicing a plurality of splicing blocks, the upper end of the splicing block is provided with a rack slide groove opening downward, the lower end of the splicing block is provided with a limiting protrusion, and roller running surfaces with a height lower than the limiting protrusion are provided on both sides of the limiting protrusion; above the limiting protrusion, the upper end of the splicing block is provided with a downwardly extending protective strip, and the width of the protective strip and the limiting protrusion is matched with the circumferential groove of the hanger roller. The splicing block is provided with a limiting protrusion, and roller running surfaces with a height lower than the limiting protrusion are provided on both sides of the limiting protrusion, and a protective strip is provided above the limiting protrusion. The hanger roller rides on the limiting protrusion, and the roller contacts the roller running surfaces on both sides and runs on the roller running surfaces. The limiting protrusion and the protective strip match the circumferential groove of the hanger roller, thereby limiting the hanger roller up and down to prevent the hanger from derailing when turning.

[0008] In order to facilitate the clothes hanger roller to enter or leave the elbow assembly, a guide head is arranged on the protection strip at the input end or both ends of the elbow assembly.

[0009] Preferably, the width of one end of the guide head away from the elbow assembly is narrower than that of the other end.

[0010] The splicing block can be designed in one piece or in a split design. The splicing block in a split design includes a base, an upper cover and a protective plate. One side of the base has a side wall, one end of the upper cover is connected to the top of the side wall, and the other end of the upper cover is connected to the protective plate; the roller walking surface and the limit protrusion are arranged on the other side of the base, the rack slide is arranged on the upper cover, and the protective strip is arranged on the protective plate. The split structure can be formed into an integrated structure by integrally forming the connection between the components.

[0011] Preferably, a guide head is provided on the protection strip at the input end or both ends of the elbow assembly.

[0012] Preferably, the splicing blocks include inner curved splicing blocks and outer curved splicing blocks.

[0013] The utility model also provides a hanging conveyor line, comprising a straight rail section and a curved rail section, wherein the curved rail section is composed of the elbow assembly described in the utility model.

[0014] Preferably, the straight rail section and the curved rail section are connected by fasteners.

[0015] The utility model discloses an elbow with a clothes hanger roller running surface, a limiting convex strip is arranged on the clothes hanger roller running surface, a protective strip is arranged above the limiting convex strip, and the limiting convex strip and the protective strip match the circumferential groove of the clothes hanger roller, thereby limiting the clothes hanger roller up and down, and preventing the clothes hanger from derailing when it is bent.
