Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to a display device for a shelving device that is capable of efficiently picking a predetermined number of articles from a shelf in which a large number of different kinds of articles are partitioned and stored.

Conventionally, the shelves have sloped sides, and the shelves facing the front are used as storage locations for separate items.Using the slope of the shelves, when an item case in the front is removed, a new case in the back is placed in front. Using floating shelves with a structure that allows them to come out, a large number of these are placed in a storage area such as a warehouse, and workers sequentially take out a predetermined quantity of a predetermined type of product based on an order list. Order picking systems are known.

Normally, in the picking operation, a worker has a list (slip) to be picked and picks out a predetermined number of predetermined items based on the list. However, in this method of taking out items while looking at a list, the worker first looks at the slip and knows the item to be taken out, then searches for the storage location of that item, confirms it, reads the quantity on the slip, and then takes out the specified quantity. The picking time is spent more on searching for a storage location, confirming the quantity to be taken out, checking, etc. than on the picking operation, which increases the working time and has a large impact on work efficiency in a large-scale system.
Furthermore, errors in the type and quantity of articles to be taken out are likely to occur due to misreading of printed matter.

Therefore, in large-scale systems of this type, quantity indicators are installed at each article storage position on each floating shelf.
Attempts have been made to display the quantity of items to be taken out under computer control, and when the taking out is completed, a pushbutton switch installed in parallel on each display notifies the computer that the work has ended, and the display disappears. It is being

However, in this case, it is necessary to install a display at each storage position, and therefore, complicated wiring is also required. A general floating shelf is a small and relatively inexpensive shelf with a width of about 150 cm, so installing a large number of displays and the wiring required for it would be extremely expensive and impractical. isn't it.

The present invention is intended to solve the above-mentioned problems, and an object of the present invention is to provide a display device for a shelf device that allows accurate display with a simple display device.

Embodiments of the present invention will be described in detail below with reference to the drawings.

FIG. 1 shows an embodiment in which the present invention is applied to a fluidized shelf 10, in which a plurality of shelves 11, 11, . . . are provided so as to be inclined forward. Articles 12, 12...
Cases 13, 11, 11, 11...
13..., and cases 13, 13... of the same articles 12, 12... are arranged behind it. The articles 12, 12... are taken out from the front of the shelves 11, 11..., and when one case 13 is empty, that case 13 is removed, and the next case 13 comes forward due to the inclination, and the next one is taken out from there. Do the following. Replenishment of the articles 12, 12, . . . is carried out by placing a new case 13 at the rear of the shelf.

Such fluidized shelves 10 are arranged side by side facing a belt conveyor 14, for example, as shown in FIG. 2, and an operator takes out a predetermined number of predetermined articles 12, places them on the conveyor 14, and sends them outside. Of course, there is no problem in transporting it using a transport vehicle or the like. 15 is a pallet storage shelf.

The fluidized shelf 10 in FIG. 1 has articles 12 to be taken out,
12... and a device for displaying the quantity thereof is provided. Indicator lights (i.e. item indicator lights) 16, 16... are provided at the front of each stage of the shelves 11, 11... for each section position, and when the lights are lit, the item 12 at that position is displayed.
Indicates what should be retrieved. Also, a digital display 17 for displaying the quantity of articles 12 to be taken out at an appropriate position on the shelf 10, for example, at the top center as shown in the figure.
is provided. Furthermore, a push button switch 18 is provided for generating an end-of-operation signal at an appropriate position on the shelf 10.
is provided.

The control system of this display device is shown in FIG.

Information regarding the article to be taken out sent from the host control device (for example, a computer) 19 is stored in a storage circuit in the central data display control device 20. The information includes, for example, the order number, the number of the shelf unit in which the item is stored, the item number (1-12 in the embodiment of FIG. 1), and the number of the item.

This information is transmitted to each shelf 10 via the bus 21 after receiving information on all articles to be taken out from the host controller 19.

Each shelf 10 is provided with a control box 22, inside which is provided a circuit 23 for identifying a shelf unit number and a memory circuit 24 for storing item numbers and article quantities. When the shelf unit number identifying circuit 23 identifies that the shelf unit number of the input number matches its own shelf number, it generates an output signal and sets the storage device 24 to store the item number and article quantity. . The stored article quantity signal is given to the display drive circuit 25 to display the number of the quantity on the display 17, while the stored item number is applied to the display conversion circuit 26 to display the item corresponding to the item number. light 16
lights up.

Although the control box 22 can be installed at any position on each shelf 10, it is convenient to install it if it is integrated with the digital quantity display 17. The pushbutton switch 18 for ending the operation may be wired separately from the bus 21, but the bus 21 is used to transmit the pulse generated by closing the pushbutton switch 18 to the central data display control device 20. You may.

When the signal from the operation end pushbutton switch 18 is received by the central data display control device 20,
The internal controller reads and transmits data for the next item number item in that shelving unit in the data storage device. Therefore, when the operator finishes taking out one article and presses the pushbutton switch 18, the item indicator light 16 at the storage position of the next article to be taken out lights up and the quantity is displayed.
When all the articles have been taken out from one shelf, the next display will not be displayed even if the push button switch 18 is pressed. Therefore, the worker moves to another shelf where the display is displayed and performs the same work.

If one worker does all the work, the central data display control device 20 may send data one after another in the order of the shelf units, but generally multiple workers do the picking work. many. Therefore, it is generally appropriate to display all the shelves from which articles are to be taken.

As explained above, according to the present invention, the storage position and quantity of items to be taken out are displayed.
This eliminates the need for tasks such as searching for locations and checking the quantity of slips, which not only greatly speeds up the work, but also greatly reduces picking errors such as misreading slips and misplacing items. be able to. Furthermore, since there is no need to hold a slip, workers can use both hands freely, which also improves efficiency.

Moreover, the equipment for this purpose is simple, as all that is needed is to install an indicator light at each compartment position, and the expensive digital display that displays the quantity, its drive circuit, and one end pushbutton switch are installed in each shelf unit. Costs can be reduced and wiring can be simplified.
