Problems solved by technology

[0005] However, for the above-mentioned conventional conveyor chain, that is, the conveyor belt, since the conveyor belt module is constituted by the first member and the second member that are combined from the vertical direction, and the balls are clamped between the first member and the second member, the conveyor belt Sliding wear occurs between the module and the balls
[0006] Therefore, for this conveyor belt, although the conveyor belt module and balls are also made of polyacetal with good self-lubricity to suppress sliding wear, the combination of the same materials has a high affinity for the contact surface. Therefore, it is easy to stick, so the sliding wear cannot be sufficiently suppressed
[0007] Therefore, the conveyor belt module and balls made of the same material will wear out at an accelerated rate, causing the belt to vibrate and the height of the conveying surface to fluctuate, making it difficult to stably convey the articles placed on the balls. There is a problem that the dust generated by this sliding wear tends to contaminate the conveying environment

Embodiment Construction

[0025] The present invention is a conveyor chain, wherein, a plurality of chain links with a plurality of hinge parts protruding alternately from the front end edge and the rear end edge are respectively connected in the length direction of the chain by means of hinge pins, and the front and back sides of the aforementioned chain links The protruding free balls are rotatably held by the links, wherein either one of the free balls and a ball holding portion holding the free balls is made of polyacetal, and the other is made of polyamide or polyester. Formed, thus, the free balls held in the conveyor chain can be rotated in all directions, thereby exerting the function of changing the direction of conveyance and the function of double speed that can be conveyed in the entire 360-degree horizontal plane, and can suppress the wear of the free balls and ball holding parts, Thus, stable transmission can be performed, and if it is such a device, its specific form can be arbitrary.

Abstract

Conveyor chains are provided which comprise free balls which are free to rotate in all directions thereby allowing for the stable conveyance of articles in any direction in the entire horizontal plane and at an increased speed in the direction of conveyance with reduced contamination in the conveyance environment. A conveyor chain 100 comprises a number of chain links 110 comprising a plurality of hinge portions 112 in a zigzag formation protruding from the front and rear end edges that are connected to each other in the longitudinal direction of the chain through hinge pins 120 . Free balls 131 protrude from both the surface and back sides of the chain link 110 and are free to rotate while held in the chain link 110 . Either the free balls 131 or ball holding portions 132 , which hold the free balls 131 , is made of polyacetal while the other is made of polyamide or polyester.

Description

technical field [0001] The present invention relates to a conveyor chain suitable for carrying and conveying box-shaped and plate-shaped objects with a flat bottom, in particular to a conveyor chain holding free balls protruding from the front and back sides of the chain link and rotating. Background technique [0002] Conventionally, as a conveyor chain for carrying conveyed articles, there is a conveyor belt in which freely rotatable balls or rollers are provided in a plurality of conveyor belt modules, and articles are sorted during conveyance, and then slide and discharge to the conveyor belt. One side of the line, and make it have double speed function (refer to patent document 1). [0003] In this kind of conveyor belt, the hinge parts respectively formed in the first part and the second part of the first part and the second part of the conveyor belt module that carry and convey the article are connected by hinge pins, and in order to slide and discharge to the side of...
