Claims (1)

[Claim for Utility Model Registration] A leg guide protruding to be inserted between the legs of a chair and front legs on both sides are placed on the trolley and are tilted and arranged side by side on both sides so as to be guided diagonally upward. A lift chain is composed of a leg-resting rail, a link group with protruding hooks, and is arranged above the leg-resting rail, and a lift chain is rotatably arranged at the tip of the lift chain. A lift chain is provided that lifts up the horizontal bar installed between the front legs of a chair approaching along the leg guide and locks it to the hook, and the lift chain locks the horizontal bar to the hook. Each time the chair stops and moves one link section at a time, the chairs are automatically collected in sequence along the leg resting rail, and the chairs thus collected are laid down by moving the lift chain in the opposite direction. In an automatic cable laying machine, from the horizontal bar locking position between the links at the turn-back position at the end of the lift chain and the hooks with a gap between them in the retrieval direction, the horizontal bar locking position between the hooks further adjacent in the retrieval direction is A horizontal bar detection sensor is provided at the lowest recovery position for detecting that the horizontal bar is locked, and this horizontal bar detection sensor extends along the lift chain direction and is curved upward. The lever includes a spring-biased lever that resists downward pressure, and a detection element that detects when the lever is pressed downward, and the peaks are connected to the lift chains on both sides. The automatic chair laying machine is disposed at an intermediate position between the lowest recovery position and is pressed downward by the horizontal bar that is locked to the closed hook.
