Claims

[Scope of utility model registration request]

A movable safety fence that blocks the pallet receiving opening of a setup station where pallets are transferred using an automatic guided vehicle, and which surrounds and blocks the opening on three sides when no pallets are placed on the opening. , a set of four rotating fences arranged in a U-shape around the periphery of the opening with one end supported by a rotating shaft in order to block the opening by straddling the entrance/exit of the opening in the closed position when a pallet is placed on the pallet; A rotation mechanism that reversibly rotates each fence, a means for detecting the limit rotation position of the fence, and control of the cart toward and away from the opening based on the position information from the detection means and the position information of the cart. A movable safety fence characterized by comprising: a control system that controls forward and reverse driving of the rotation mechanism in response to the movement of the rotation mechanism;
