Claims (1)

[Claim for Utility Model Registration] A trolley has leg mounting rails arranged side by side on both sides so as to guide the legs diagonally upward, and a hook arranged above the leg mounting rails. A lift chain equipped with a large number of protruding links, and a lift lever that lifts up the horizontal bar between the front legs of a chair approaching the top of the lift chain and locks it to the hook, The horizontal bar is locked to the hook and the lift chain is 1
An automatic chair laying machine that automatically collects chairs in sequence along the leg resting rail each time it moves link sections, and then lays the chairs that have been collected in this way by moving the lift chain in the opposite direction. In this step, the lift chain is constituted by a group of consecutive links with hooks in a number corresponding to the maximum number of chairs to be recovered and the remaining groups of links without hooks, and in order to detect the initial position of the recovery operation of the lift chain, An automatic chair laying machine characterized by being equipped with a sensor that detects when a link reaches a predetermined position.
