Claims

[Claims for Utility Model Registration] 1. A drive chain 1 that is wound around a plurality of sprockets and driven in circulation includes a guide body 9 such as a roller.
In a supply conveyor, the front part of an attachment 4 for pushing conveyed objects, which is provided protruding from the rear part, is pivoted with a pin 8, and the attachment 4 is moved by a drive chain 1. When the front part of the attachment 4 reaches the sprocket 2 and the attachment 4 descends, the guide body 9 of the attachment 4 is fitted into and supported at a rear position on the side of the sprocket 2 located at the front end of the sprocket. The guide body 9, which has a plurality of recesses 22 on the outer circumferential surface and which are fitted into the recesses 22, is simultaneously lowered by the same dimension as the pin 8 to remove the attachment 4.
A guide wheel 10 is provided which rotates at the same speed as the sprocket 2 in order to lower the sprocket in a normal position, and a guide body 9 fitted into a recess 22 of the guide wheel 10 is disposed near the outer peripheral surface of the guide wheel 10. A lowering control device for an attachment for pushing a conveyed object in a supply conveyor, characterized in that an outer peripheral guide body 18 is separately provided to prevent the attachment from detaching from the conveyor. 2. Lowering of an attachment for pushing conveyed objects in a supply conveyor according to claim 1, wherein the guide wheel 10 is constituted by a chain sprocket wheel having the same dimensions and the same number of teeth as the sprocket 2. Control device.
