Description

  BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a picking system for picking up stored articles in a storage unit for storing many articles, and more particularly, to a display device used for the picking system.

  The picking system in physical distribution includes a storage shelf 2 (not shown; the same applies hereinafter) as a storage means for articles. In the picking system, a plurality of storage boxes 3000 (not shown, the same applies hereinafter) are usually placed on the storage shelf 2, and one or more articles of the same type are stored in each storage box 3000. The picking worker M takes out necessary articles in accordance with a command from a control means for managing the picking system, puts them in the collection box 3 on the conveyor 9, and transfers them to the shipping line. For example, a large number of storage shelves 2 are arranged side by side, and a conveyor line (not shown; the same applies hereinafter) is provided along the storage shelves 2. Into the collection box 3.

  In this case, the display device 4 is arranged on the front surface of the storage shelf 2 so that the worker M can identify the storage box 3000 for articles to be taken out of the plurality of storage boxes 3000. The display device 4 is composed of, for example, a 7-segment LED, and can display the number of articles to be taken out.

  As a picking system using a display device, the following Patent Document 1 is known. In Patent Literature 1, as shown in FIG. 3 which is a plan view showing a conventional display device, an operator needs a required number of articles from a plurality of storage boxes placed on each of a plurality of storage shelves 2. Take out. In this case, a display device 4 is provided corresponding to each storage box. The display device 4 includes a lighting display unit 42 (not shown, the same applies hereinafter) for indicating a digital picking instruction and a work completion input, and a digital display unit 43 (not shown, the same applies hereinafter) for indicating the number of items to be picked. Is configured. Generally, not only Patent Document 1, but a seven-segment LED is used for the digital numerical display unit.

JP-A-2006-222426

  The display device 4 is configured to display the quantity on the digital display unit 43. However, in the case of an unskilled worker, or a case where even a skilled worker is distracted or has a high degree of fatigue. For example, there is a case where the article in the storage box 3000 is picked up by mistaking the article arranged on the display device 4 which is instructing the picking and the article arranged below. In order to prevent such erroneous picking, for example, it is desired that a symbol indicating an upward or downward instruction can be displayed on the digital display unit 43 of the display device 4 which is instructing the picking.

  In order to display a symbol indicating an instruction for upward or downward on the digital display unit 43, the size of a 7-segment LED (Light Emitting Diode) built in the digital display unit 43 must be increased. When the size of the LED is increased, the size of the display device 4 also needs to be increased. However, picking work in recent years has tended to be of a large variety and small quantity, and the storage box 3000 has become smaller and the number of types has increased. 4 needs to be reduced, which contradicts the need to increase the size of the display device 4 described above.

  Therefore, a main object of the present invention is to arrange symbols indicating up and down without changing the size of the display device, and a secondary object is a symbol indicating up and down without reducing the visibility of the display device. It is to arrange.

  In order to solve the above-described problem, a display device according to a first aspect of the present invention includes a first display unit that emits a numerical segment in which a plurality of segments capable of expressing a single-digit numerical value are arranged in a plurality of digits, A second display unit, which is arranged in an area formed by at least one segment among a plurality of segments constituting the numerical value segment and emits a direction segment for indicating a direction, displays a numerical value on the second display unit and the first display unit. And a control unit for controlling the second display unit to emit light simultaneously with or independently of the display.

  Here, the size of the 7-segment LED does not increase because the second display unit is arranged in a blank portion surrounded by the light-emitting elements of the 7-segment LED, for example, related to the first display unit. The size of the display device does not increase. By arranging the direction indicator on the 7-segment LED, the worker M can be instructed on the direction of the storage to be picked on the display device.

  As a fourth aspect of the present invention, in any one of the first to third aspects of the present invention, the color of the second display section is a color different from the color of the light emitting element of the first display section. It can be configured as follows.

  When the color of the second display portion is different from the color of the light emitting element of the first display portion, visibility is improved.

  By making the color of the light emitting element of the first display unit (for example, a 7-segment LED) different from the color of the second display unit (for example, a direction indicating unit), visibility is improved and work efficiency is improved. At this time, as the first color and the second color, a color that does not cause the worker's eyes to feel tired due to ergonomics, for example, orange as the first color and green as the second color is selected. be able to.

  When the second display unit (direction indicating unit) emits light, visibility is improved, and work efficiency is improved. At this time, for example, by highlighting including blinking, the ability to call attention of the worker can be further improved.
