JPS6438306A - Device for supplying electricity to pallet in pallet conveyer - Google Patents

Abstract

PURPOSE:To make inspection on a conveyer possible by providing a start end part, a terminal end part and a middle part of a transfer passage of a pallet with respectively specified electricity supply units with which pallet electricity supply part is brought into sliding contact, and by providing the start end and terminal end part with electricity supply changeover switches. CONSTITUTION:At a start end part of a conveyer 30, an electrode of a pallet 40 comes into contact with an electrode 54 of a start end electricity supply unit 50 and at the same time turns a switch 60 on and moves while receiving electricity supply. Then the electrode of the pallet 40 comes into contact with a first electrode 55 of a continuous electricity supply unit 51 to receive electricity supply. At the same time, the switch 60 is turned off and the pallet 40 moves to the terminal end part by means of electricity supply from the continuous electricity supply unit 51 and then receives electricity supply from a terminal end electricity supply unit 52. A switch 61 is then turned off to stop the electricity supply and to perform inspection. The switch 61 is then turned on to resume the electricity supply and to move the pallet 40. With this constitution, inspection can be performed on the conveyer.
