Japanese Patent Laid-Open No. 9-40158 ([0011]-[0014], FIG. 1)

  In the above-described accumulation conveyor of Patent Document 1, no particular consideration has been given to the piping path connecting the first actuator and the second actuator 130 arranged across a pair of conveyor frames.

  For example, as shown in FIG. 7, in the case where the first actuator 120 and the second actuator 130 are disposed between the pair of conveyor frames 2a and 2b, the first actuator 120 and the electromagnetic valve are arranged. It is necessary to install a pipe 121 that connects 140 and a pipe 131 that connects the second actuator 130 and the electromagnetic valve 140. However, when the air pipes 121 and 131 are arranged between the pair of conveyor frames 2a and 2b, the air pipes 121 and 131 hang down as shown in FIG. 7, and vibration when the conveyor device is driven. Therefore, there is a problem that the air pipes 121 and 131 are damaged.

  In order to prevent the air pipe from drooping, a member provided between the pair of conveyor frames and the air pipe are secured to prevent the air pipe from drooping and vibration of the pipe. However, when the air pipe is simply lashed, the air pipe is not protected in an exposed state, so that there is a problem that other equipment is brought into contact with the air pipe during maintenance to damage the air pipe. Furthermore, in order to prevent damage to the air piping, the air piping is also installed and protected in a protective tube, but there is also a problem that it must be disassembled for inspection and maintenance of the air piping. .
