構成したことである。<Means for Solving the Problems> Therefore, the present invention was devised to solve the above problems, and it is a technology that prevents the limit switch from easily coming off from the operating fitting due to the vibrations and shocks of the traveling pallet. This will be a major issue. The means for achieving this technical problem is to provide a limit switch for detecting a predetermined stop position at the rear central part of the traversing pallet, and to provide an actuating fitting for operating this limit switch at the predetermined stop position. The operating fitting is shaped to have a predetermined length in the left and right running directions from the stop position, and the detection signal of the limit switch is transmitted for a set time corresponding to the time required for the limit switch to move the operating fitting over the predetermined length. A delay circuit is provided to hold the limit switch, and when the limit switch is actuated by the actuation metal fitting, the detection signal of the limit switch is held by the delay circuit, and the limit switch moves a predetermined length of the actuation metal fitting to stop the limit switch. When the stop position is reached, a limit switch detection signal is transmitted from the delay circuit to the traversing pallet driving section to stop the traversing pallet at the stop position.

The delay circuit that receives this detection signal holds the signal for a set time and transmits it to the traversing pallet drive unit when the limit switch moves a predetermined length of the operating metal and reaches a predetermined stop position. This driving section is stopped to stop the traversing pallet at a predetermined stop position. Therefore, at this time, the operating contact of the limit switch sufficiently rides over the operating metal fitting and is located almost in the center of the operating metal fitting, so that even if the traversing pallet vibrates or receives an impact, the limit switch will easily come off from the operating metal fitting. Things will disappear.
