Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a carrier device that can carry an item along a carrying path and carry it out to the side of the carrying path.

(Prior Art) For example, goods are conveyed along a conveying path, and at a plurality of places of this conveying path, goods are selectively discharged to the side of the conveying path by product type or destination. The transporting device, called a device, uses a scraper or pusher to push the items on the conveyor that form the transporting path to the side, or a cart or slat traveling along the transporting path that is tilted to the side. There is a system that drops the above items to the side by weight, but there is a limit to the items that can be sorted, such as small items, bulk items, lightweight items, thin items, items with poor bottom condition, etc. It is impossible to sort items that can only be transported.

As a carrying device applicable to carrying and sorting such goods, there is one shown in Japanese Patent Laid-Open No. 62-74823.

This transporting device basically has a conveyor belt (conveying tray unit) that moves along a conveying path (guide rail) and a belt for supporting an article having a conveying direction that intersects the moving direction of the conveyor. A structure is provided in which an operating mechanism (tray unit sorting actuating device) for driving the belt on the side of the carrier is provided on the side of the carrier path. Specifically, the carrier has a carrier direction that intersects the moving direction of the carrier. An endless belt having is installed via a pair of pulleys on both sides, a plurality of guide wheels are attached to this belt, and a pair of linear tracks on both sides that engage with the guide wheels on the carrier side are provided along the carrier path, An inclined track that connects the linear tracks on both sides to each other in an X shape is provided in the transport path, and a gate is vertically movable at the intersection of the linear track and the inclined track. By switching the gate on the roadside, the guide wheel on the side of the moving carrier is sequentially guided from one straight track to the other straight track via the slanted track, whereby the endless belt of the moving carrier. Is driven toward the side of the transport path so that the articles on the belt are carried out to the side of the transport path.

However, in the carrying device disclosed in Japanese Patent Laid-Open No. 62-74823, the products are carried while being supported on a belt, and the products are carried out by driving the belt, so that it can be applied to carrying and sorting various products. However, in some cases, when the belt is driven from a stationary state to carry out the goods, the goods may slip with respect to the belt, which may hinder the accurate carry-out of the goods.

In this respect, for example, the article sorting conveyor described in Japanese Utility Model Laid-Open No. 63-139229 is known. In this article sorting conveyor, a large number of elastic projections are provided on the entire surface of the article supporting surface of the belt so as to hold articles that easily roll.
