Description

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

A picking system in physical distribution is equipped with an article shelf as a means for storing articles. In a picking system, a plurality of storage boxes are usually placed on an article shelf, and one or more articles of the same type are stored in each storage box. A picking operator picks up the necessary articles according to the instructions of the control means that manages the picking system, puts them in collection boxes or the like on the conveyor, and transfers them to the shipping line. For example, a large number of article shelves are arranged horizontally, and a conveyor line is provided along them, and a picking operator picks up articles to be picked from the shelves and puts them into collection boxes flowing along the transfer line.

In this case, a display is arranged in front of the article shelf so that the picker can identify the storage box of the article to be taken out of the plurality of storage boxes. The indicator is composed of, for example, a 7-segment LED, and can display the quantity of articles to be picked up.

The following patent document 1 is known as a picking system using a display. Patent document 1 provides a push switch that is excellent in waterproofness and dust resistance, has good light transmission, and can reduce malfunctions when pushed, and a picking display device to which this push switch is applied. .

Registered Utility Model No. 3003364 JP 2016-222426 A

In Patent Document 1, as shown in FIG. 1, the display device assembled with complicated components does not have a flat surface as shown in FIG. Furthermore, although omitted in FIG. 3, if the auxiliary switch shown in FIG. 2 is included, the presence of the display itself becomes conspicuous even when the display is turned off.

Patent Literature 2 discloses a basic description of a picking system and a display.

FIG. 4 is a diagram showing a conventional display 40 including the display device of Patent Document 1. The display 4 includes an illuminated switch 42 and a 7-segment LED 43. As shown in FIG.

However, in the conventional display, since the button portion and the quantity display portion are clearly defined, the presence of the display itself stands out even when the light is off.

Due to the nature of the indicator, visibility when lit is given top priority. Therefore, the present invention provides a picking system that makes it possible to further improve the visibility of lit indicators by making the unlit indicators inconspicuous among a large number of indicators installed on an article shelf. intended to provide

Therefore, according to the present invention, the indicator has a flat surface and an inconspicuous color to eliminate the sense of presence when the indicator is turned off, so that only the illuminated indicator stands out so that the position of the button to be operated can be recognized. To provide an easy picking system.

In order to solve the above problem, the present inventor has found that if the visibility performance during lighting is the maximum at present, it will be possible to further improve the visibility performance during lighting by providing a function that makes it inconspicuous in the non-lighting state. Focused on the point.

Based on this, in order to achieve the above object, the present invention provides an article shelf on which a plurality of articles to be picked are placed in a picking system, and a picking device in the vicinity of the article to be picked from the article shelf and the picking device. a plurality of indicators arranged at positions corresponding to the articles to be picked; and control means for lighting or blinking the indicators corresponding to the storage boxes of the articles to be picked by the worker, wherein the plurality of indicators The vessel is characterized by having a flat surface.

In this case, the display is characterized in that the upper surface is coated with light transmission reducing means for reducing light transmission.

Further, the light transmission reducing means is characterized in that the surface thereof is matted.

Furthermore, the display comprises at least one light emitting component covered by the light transmission reducing means, the light transmission reducing means optically blocking the light emitting component when it is extinguished, and It is characterized in that it transmits light emitted from the light-emitting component while it is blinking.

According to the present invention, the indicator has a flat surface and an inconspicuous color to eliminate its presence when the indicator is turned off, so that only the illuminated indicator stands out so that the position of the button to be operated can be recognized. An easy picking system can be provided.

FIG. 4 is a diagram showing how a worker takes out an article from a storage box that stores articles in the picking system of one embodiment according to the present invention; FIG. 2 is a front view of the article shelf of FIG. 1; Shows the display in this embodiment, (A) is its plan view, (B) is a cross-sectional view along line XX of (A), and (C) is a state in which the film sheet of (B) is removed. A plan view, and (D) is a plan view of the lighting switch 42 and the numeral portions of the 7-segment LED 43 being lit. FIG. 10 is a plan view showing a conventional indicator;

Hereinafter, the present invention will be described in more detail using the embodiments shown in the drawings, but the present invention is not limited to these, and various modifications can be made without departing from the gist of the present invention. It is possible to do so, and is limited only by the technical idea described in the claims.

FIG. 1 is a diagram showing how a worker takes out an article from a storage box containing articles in a picking system according to one embodiment of the present invention. In FIG. 1, the worker 6 takes out the number of articles indicated by the 7-segment LED 43 from the storage box 2 based on the instruction state 41 of the display unit 4, presses the switch 42 to turn it on, and completes taking out. Enter It should be noted that the article shelf may be divided into booths, and the storage box may be omitted.

It should be noted that the article shelf 1 shown in FIG. 1 is a work zone assigned to one worker. assigned work zones for picking.

2 is a front view of the article shelf of FIG. 1; FIG. A plurality of storage boxes 3 are placed on a plurality of storage racks 2 of the article shelf. A display 4 is provided at a corresponding position near each storage box 3 .

FIG. 3 shows the display device 4 in this embodiment, (A) is a plan view thereof, (B) is a cross-sectional view along the xx line of (A), and (C) is the film sheet of (B). (D) is a plan view of the illuminated switch 42 and the numeral portions of the 7-segment LED 43 are illuminated. In FIG. 3B, the indicator 4 has an illuminated switch 42 and a 7-segment LED 43 mounted on a substrate 44 and is entirely covered with a film sheet 45 .

In FIG. 3A, the film sheet 45 on the upper surface of the display 4 is a blackish gray smoke film sheet which is light transmission reducing means for reducing light transmission. FIG. 3C is a plan view of the display 4 with the film sheet 45 removed. That is, when the illuminated switch 42 and/or the 7-segment LED 43 are not lit or blinking, the film sheet 45 obscures the illuminated switch 42 and the 7-segment LED 43 from the operator as shown in FIG. I can only see Note that the film sheet 45 is not limited to the configuration of this embodiment as long as it is a light transmission reducing means.

On the other hand, when the illuminated switch 42 lights up or flashes, as shown in FIG.

Therefore, since the upper surface of the indicator 4 is covered with the flat film sheet 45, the illuminated switch 42 and the 7-segment LED 43 that are not lit or blinking are inconspicuous, so the position of the indicator 4 can be easily recognized. can.

In this case, since the surface of the film sheet 45 is matted, there is no risk of reflection of the lighting in the factory. Therefore, the visibility of the indicator 4 being lit or blinking is improved, and the existence of the indicator 4 being extinguished is made inconspicuous.

In the present invention, the display has a flat surface and an inconspicuous color to eliminate its presence when it is turned off, and only the lit display stands out so that the position of the button to be operated can be easily recognized. Therefore, industrial utility value can be enhanced.
