Claims

[Scope of utility model registration request]

(1) In a conveyor equipped with a plurality of current collectors that can be contacted at predetermined positions on the sliding plate attached to the back side of the pallet placed on the pallet, a proximity switch is provided, and a A plurality of pairs of sliding plates formed by conductively connecting a plurality of sliding plates are provided on a pallet, and a current collector for power supply and a current collector for detection are brought into contact with each pair of sliding plates. A safety device for a conveyor with a current collector, characterized in that it controls on/off of the power supplied from the power source to the pallet side via the current collector based on the presence or absence of contact with the sliding current plate and a proximity switch.

(2) The proximity switch is a practical device characterized in that the proximity switch and the plurality of current collectors are arranged so as to be scattered with respect to the flow direction of the conveyor and a direction perpendicular to the flow direction. A safety device for a conveyor with a collector according to claim 1 of the patent registration claim.
