Circular conveying apparatus

Abstract

An objective of the invention is to realize a circular conveying apparatus which can reduce bad conveying or conveying pollution generated with micromation of conveyed objects, and is helpful to realize high speed of conveying height or high density of conveying forms. The circular conveying apparatus (10) is provided with a recycling transfer portion (X) which makes conveyed objects excluded by a supply side arrangement path (11a) transfer to a recycling side conveying path (12a), and a supply transfer portion (Y) which makes conveyed objects conveyed by the recycling side conveying path (12a) transfer to the supply side arrangement path (11a). In the recycling transfer portion (X), a downstream end of an excluding path of the conveyed objects from the supply side arrangement path (11a) is above an upstream portion of the recycling side conveying path (12a) and hangs over, or in the supply transfer portion (Y), a downstream end of the recycling side conveying path (12a) is above an upstream portion of the supply side arrangement path (11a) and hangs over.

Description

technical field [0001] The present invention relates to a circulating conveying device, and more particularly, to a structure of a conveying body of a circulating conveying device that returns conveyed objects removed from an arraying path to an upstream side while aligning conveyed objects on an arraying path, and resupplies them to the arraying path. Background technique [0002] In general, there is a type of conveying device configured to convey conveyed objects in an arrayed state uniformly in a desired posture by controlling the posture of conveyed objects during conveyance. As such a conveying device, for example, a vibrating conveying device called a parts feeder or a linear feeder is known. In such a conveying device, the conveyed objects that are not in the desired posture are shaken off or blown away by airflow while conveying the conveyed objects on the alignment path, thereby sorting the conveyed objects or turning the conveyed objects, etc. By changing the pos...

AI Technical Summary

Problems solved by technology

If the miniaturization of the conveyed objects develops in this way, the following problems are likely to occur: the conveyed objects are clogged in the conveying path or adhered to the conveying surface due to dust, etc. Transport pollution and other issues

In addition, in the above-mentioned recovery transfer unit and supply transfer unit where the two transfer bodies face each other with a slight gap and height difference, there are also situations where the transfer operation is hindered by the stuck objects or dust clogging.

[0009] In addition, since the assembly line speed in the production line of the electronic system is also increasing at the same time as the miniaturization of the above-mentioned electronic devices, an increase in the speed of the conveyance and a high density of the conveyance form are also required for the conveyance device. When an electronic device in an improper posture is accidentally supplied, the assembly line stop time for recovery will increase the loss, so the requirement for the alignment accuracy of the transported objects is also increasing.
