Further, the PC 30 has a control screen 28 provided with a liquid crystal panel having a function of displaying information related to sorting work and a function of inputting information to the control means 25 and a touch panel provided with input means 27 such as a touch pad. For example, as information on the sorting work, all of the article frontages 5 are displayed on the screen, and the state in which the gate 7 for inserting the articles is opened is displayed on the screen. The operator considers the location of the open gate 7 displayed on this screen and puts the article 22 into the article frontage 5.

The PC 30 does not operate the rotating means 11 with respect to the control means 25, for example, when the foot switch 34 is stepped on by the operator when the article is thrown into the frontage of the article with the gate opened. The state is set, and a confirmation signal of the completion of loading into the current frontage 5 of the article is transmitted. In addition to the foot switch 34 for stepping on the foot, the optical path of the light emitting / receiving means may be blocked by the foot.

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. 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.

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.

Next, the details of the rotating means 11 of the gate 7 according to this system will be described.
In the present embodiment, a vertical frame 3a, a horizontal frame, a rotating means holding frame 3c provided on the front surface of the horizontal frame, and an article frontage 5 having four vertical rows and four horizontal rows formed of a shelf board are provided. , The rotating means 11 attached to the rotating means holding frame 3c is attached to the upper part of each article frontage 5.

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 driven by the controlling means 25 of the PC 30, is attached to each of the plurality of article frontages 5, and drives the linear driving means 40.

As shown in FIGS. 3A and 4, the cylindrical body 13 is provided with a cam follower mounting annular body 17, to which a cam follower 18 is mounted and an electromagnetic valve connected to the control means 25 of the PC 30 (shown). The cam follower 18 gives a driving force to rotate the cylindrical body 13 from the cylindrical cam 50 that linearly moves the cylindrical body 13 provided in the cylindrical body 13 in the axial direction by the air supplied through the cylindrical body 13. ..

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.

As shown in FIGS. 2 and 3B, the cylindrical body 13 is provided with two stoppers (31a, 31b) having a depression / elevation angle adjusting function in the cylindrical body 13 in order to regulate the elevation operating range of the gate 7. One of the stoppers (31a, 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. Is. 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.

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.

Next, in the present embodiment, a case where the work of sorting the goods to each goods frontage 5 by the PC 30 will be described as an example.

In FIG. 1, when the article container 20 containing the article 22 is delivered, the worker reads the article container identification information 21 by the reading means 24, and the control means 25 of the PC 30 corresponds to the read article container identification information 21. Receives the goods sorting information to be performed and starts the goods sorting work.

Next, when the article identification information 23 of the article 22 taken out from the article container 20 is read by the reading means 24, the control means 25 of the PC 30 operates the rotating means 11 attached to the article frontage 5 corresponding to the article sorting information. The solenoid valve is opened and air is sent to the cylindrical cam 50 to drive itself linearly to open the gate 7 of the corresponding article frontage 5.
