Therefore, a holding member is provided in the cylinder so that the width of the gate can be changed. Make it possible to grant the cognitive enhancement mechanism used.

The cylindrical body is equipped with a stopper having a depression / elevation angle adjustment mechanism in order to regulate the depression / elevation operating range of the gate.

At least one of the stoppers has either an elevation angle stopper having a protrusion that regulates the upper limit of the elevation angle or a depression angle stopper having a protrusion that regulates the lower limit of the depression angle.

The gate is equipped with an afterimage effect mechanism that uses a lightweight, buffering material with a dark color on the front side and a light color on the back side, which exerts an ergonomic afterimage effect and facilitates recognition at an elevation angle. Because it is lightweight and has a buffering effect, it will not cause injury even if it hits the gate carelessly.

According to the present invention, when the number of steps of the article frontage increases in the vertical direction, the elevation position of the gate of the article frontage of each step can be set to a position where work can be easily performed, thereby utilizing ergonomics. It is possible to provide a gate assortment device capable of changing the width of the gate according to the width size of the frontage of the parts by providing the cognitive enhancement mechanism.

It is arranged so as to coincide with the central axis of the cylindrical body 13. Then, a cam slope 52a that passes through the intersection with the axial center surface of the cylindrical cam 50 and is perpendicular to each section screen perpendicular to the center surface on the tip end side, and the center axis of the cam slope 52a and the cylindrical cam 50. It has a cam slope 52b that is point-symmetrical with the upper point as the center point. Further, the linear driving means 40 is provided with a rotation preventing means 44 for preventing the cylindrical cam 50 from rotating around the central axis. As a result, the cylindrical body 13 rotates while the cam follower 18 moves along the cam slopes 52a and 52b as the cylindrical cam 50 is driven linearly.

As the linear drive means 40, an air actuator provided with an air piston, a linear motor actuator, or the like can be used, but it is preferable to use an air actuator having a simple structure. Further, when an air actuator provided with a rotation prevention mechanism for the drive shaft is used, the rotation prevention means 44 described above may not be attached.

At this time, the width of the gate 7 can be changed according to the width size of the article frontage 5. That is, the holding member 6 is attached to the fixing annular body 15 attached to both ends of the cylindrical body 13, and each gate 7 is fitted into the substantially U-shaped groove-shaped portion of the holding member 6 by the screw member 8. It is screwed. When changing the width of the gate 7, the screwed portion is removed, replaced with a gate 7 corresponding to the width size of the article frontage 5, and screwed.

As shown in FIGS. 2 and 3B, the cylindrical body 13 is provided with two stoppers (31a, 31b) having an elevation angle adjusting function in the cylindrical body 13 in order to regulate the elevation operating range of the gate 7, and the stoppers (31a) are provided. , 31b) is an elevation angle stopper 31a having a protrusion 32a that regulates the upper limit of the elevation angle, and the other one is a depression angle stopper 31b having a protrusion 32b that regulates the lower limit of the depression angle. The protrusions (32a, 32b) of the stoppers (31a, 31b) abut against the substantially U-shaped support 14 holding both ends of the cylinder 13 to stop the rotation of the cylinder 13. In this case, an elastic sheet 33 is attached to the abutting surface of the support 14, so that even if the stoppers (31a, 31b) abut against the support 14, no metallic sound is generated.
