However, in the case of Patent Document 1 described above, the opening / closing door is poorly recognized from the viewpoint of ergonomics because the elevation position of the opening / closing door of the frontage of the article cannot be changed in each step section in the article sorting operation. Moreover, the width of the opening / closing door is not changed according to the width size of the article sorting portion. Further, the specific configuration for specifying the opening / closing position of the opening / closing door is not disclosed.

Therefore, the present invention has been devised in view of the conventional circumstances as described above, and 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 is determined. By making it possible to set the position where work is easy, an ergonomic cognitive enhancement mechanism is added to the opening of the article at a particularly low step position, and the width of the gate is increased according to the width size of the frontage of the part. It is an object of the present invention to provide a gate assortment device that can be changed.

In order to solve the above-mentioned problems, in the present invention, a rotating means capable of rotating the cylindrical body by the linear driving means is attached to each of the frontages of the plurality of articles, and the linear driving means is driven. A plate-shaped gate is arranged on a cylindrical body above the article frontage so that the contents of the article frontage can be seen, and it corresponds to the width size of the article frontage. Therefore, a holding member is provided in the cylinder so that the width of the gate can be changed, and the frontage of the article at the lower step opens the gate wider than the frontage of the article at the higher step position. 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, thereby exhibiting an ergonomic afterimage effect and facilitating recognition at an elevation angle. Because it is lightweight and has a buffering effect, it will not cause injury even if it accidentally hits the gate.

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 a front view of the frontage of an article which arranged the gate assorting apparatus which shows one mode for carrying out this invention. It is an enlarged front view which shows the gate assortment apparatus. It is sectional drawing of the cam follower mounting ring part in the direction perpendicular to the central axis of the cam follower part of the gate rotating means. It is sectional drawing of the stopper part in the direction perpendicular to the central axis of the cam follower part of the gate rotating means. It is sectional drawing which cut the front and back of a cylindrical cam by the plane including a central axis.

Hereinafter, the gate assortment device 1 according to the embodiment of the present invention will be described in detail with reference to the drawings.

As shown in FIGS. 1 and 2, the gate assortment device 1 according to the present embodiment includes a vertical frame 3a, a horizontal frame, a rotating means holding frame 3c provided on the front surface of the horizontal frame, and a shelf board.

Further, a plate-shaped gate 7 is arranged on a cylindrical body 13 arranged above the article frontage 5 so that the contents of the article frontage 5 can be seen. The rotating means 11 makes the cylindrical body 13 rotatable by the linear driving means 40, is attached to each of the plurality of article frontages 5, and applies a driving force to the linear driving means 40 to provide the predetermined article frontage 5. The gate 7 is raised and lowered.

As shown in FIGS. 3A and 4, the cylindrical body 13 is provided with a cam follower mounting annular body 17, to which the cam follower 18 is mounted, and a straight line in the axial direction of the cylindrical body 13 provided in the cylindrical body 13. A cam follower 18 provides a driving force for rotating the cylindrical body 13 from the moving cylindrical cam 50.

A cylindrical cam 50 is arranged on the cylindrical body 13, and the central axis of the cylindrical cam 50 is placed in the cylindrical body 13 in which the drive shaft 42 of the linear driving means 40 is coupled to the rear end portion thereof and held rotatably. 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 cylindrical body 13 to stop the rotation of the cylindrical body 13. In this case, the abutment surface of the support 14, the elastic sheet 33 is attached, a stopper (31a, 31b) is even Tsu abutting the support 14, a metal sound is prevented from occurrence.

For example, two stoppers (31a, 31b) for specifying the elevation position are attached adjacent to the fixing ring body 15. The gate positions of the respective stoppers (31a and 31b) at the elevation angle and the depression angle can be set individually. Therefore, when the number of steps of the article frontage 5 increases in the vertical direction, it is possible to set the elevation position of the gate 7 of the article frontage 5 of each step to a position where work is easy. For example, the article frontage 5 at a low position opens the gate 7 wide, and the article frontage 5 at a high position opens the gate 7 small, which enables ergonomic opening adjustment.

Further, the gate 7 is preferably a lightweight material having a buffering action, such as a foamed polyesterol material having a black color on the front side and a light color on the back side. This coloring exerts an ergonomic afterimage effect function, further raises the awareness of which article frontage 5 to insert the article into at elevation angle, and even if the worker's hand hits the gate 7, it will not cause injury. Can be prevented.

Next, in the present embodiment, the case where the article sorting work for each article frontage 5 will be described as an example.

Open the gate 7 of the article frontage 5. At this time, the protrusion 32a that regulates the upper limit of the elevation angle stopper 31a at the time of elevation abuts on the elastic sheet 33 provided on the abutting surface of the support 14.

The operator throws the article 22 into the article frontage 5 with the gate 7 opened, and by stepping on the foot switch 34 with his / her foot, the operator sends a confirmation signal to the control device 25 that the entry into the current article frontage 5 is completed. To send.

Further, after inputting the work completion signal, the gate 7 is closed and the speaker 26 utterly conveys "Thank you" or the like to the operator. At this time, the protrusion 32b that regulates the lower limit of the depression angle stopper 31b at the depression angle comes into contact with the elastic sheet 33 provided on the abutting surface of the support 14. As a result, the worker can fully recognize the progress state of the article sorting work, and can perform the article sorting work in which work errors are less likely to occur.

In order to change the width of the gate 7 according to the width size of the article frontage 5, the screw is fitted into the substantially U-shaped groove-shaped portion of the holding member 6 of the fixing annular body 15 attached to both ends of the cylindrical body 13. The gate 7 screwed and fixed by the member 8 is removed, replaced with a gate 7 corresponding to the width size of the article frontage 5, and screwed again by the screw member 8.

Further, as the reading means 24 of the article identification information 23, a wearable reading means worn on a hand, a finger, the front surface of the body, or the like can also be used. In particular, when the article is small, the article 22 is taken out from the container with one hand, and the article identification information 23 is read by the other hand or a wearable reading means attached to the front surface of the body to read the article identification information 23 to any front surface of the article frontage 5. Since the work from the start to the completion of the article sorting work can be performed at a place or the like, the distance traveled by the worker can be shortened, and the work efficiency can be improved.
