Description

[Detailed description of the invention] [Industrial field of application] The present invention relates to a pull-out storage cabinet equipped with a plurality of inner boxes. The present invention relates to a storage device in which an inner box to be picked is indicated by lighting an indicator light in response to a command from a controller.

[Conventional technology]

Manufactured machines are affixed with nameplates and labels before being shipped. Nameplates and labels are used to improve storage efficiency,
For workability reasons, they are often stored in pull-out storage cabinets, in which case they are sorted by type and stored in inner boxes.

However, there are many types of nameplates and labels, and picking the required label correctly is not an easy task. In particular, when multiple types of nameplates and labels must be affixed to one model of product, mistakes are very likely to occur.

On the other hand, in the field of sorting shelves for storing mechanical parts, etc., as seen in "Unmanned Technology" January 1986 issue (Ryutsu Kenkyusha), p. 71, indicator lights are installed in each frontage to prevent picking mistakes. By installing a push button switch for confirmation and reading the card into the controller connected to the sorting shelf, the frontage to be picked will be automatically displayed by lighting up the indicator light.
A system has been developed in which after picking, a push button switch is pressed to check whether the picking has been done correctly.

However, such a picking system for organizing shelves does not function satisfactorily even when applied to a drawer-type storage.

[Problem that the invention attempts to solve]

In other words, the front opening of a drawer-type storage is usually much smaller than that of a sorting shelf, and even if an indicator light or a push button switch for confirmation is installed corresponding to the inner box in each opening, the opening will be much smaller. There is a concern that the wrong inner box may be pulled out.

Even if the above-mentioned picking system for organizing shelves is applied to a pull-out storage, the wrong inner box will be pulled out,
If only the push button switch is operated correctly, the picking error prevention mechanism will not operate at all, which is an inconvenience.

The present invention solves the above-mentioned inconvenience with a simple mechanism by utilizing the pull-out operation of the inner box, and provides a pull-out type storage with a simple structure that guarantees quick and reliable picking work.

[Means for solving problems]

The characteristic structure of the device of the present invention will be explained with reference to the figure. The device consists of a storage 1 and a controller 6.

On the side of the storage 1, there are indicator lights LED installed corresponding to each inner box 3, 3..., a reflector 4 attached to the outer surface of each inner box 3, 3..., and each inner box 3, 3, a photo sensor 5 is provided on the outer frame 2 of the storage 1 facing the reflector moving device that is used when the inner box is pulled out.

On the side of the controller 6, there are a selection unit 16 that selects an inner box to be picked based on external input, and a selection unit 16.
an output unit 17 that outputs a lighting command signal for the corresponding indicator light LED of the inner box selected in , and a determination unit 19 that determines which inner box has been picked based on the output of the photo sensor 5 accompanying the pulling operation of the inner box.
A comparison unit 20 compares the determined inner box and the inner box to be picked outputted from the selection unit 16, and when the inner boxes compared in the comparison unit 20 match, the indicator light LED corresponding to the inner box is turned on. A control circuit 1 comprising a second output section 21 that outputs a lights-off command signal.
2 is provided.

[Effect]

When the model or necessary items are read into the controller 6 using a cart reader or the like, the selection section 16 and the output section 17 of the control circuit 12 are activated, and the inner box containing the necessary items is displayed by lighting the indicator light LED.

When the operator pulls out the instructed inner box 3 in accordance with the lighting of the indicator light LED, the reflector plate 4 passes in front of the photo sensor 5, and a signal is generated at the photo sensor 5.

When the signal generated in the photo sensor 5 is fed back to the controller 6, the determination unit 1 of the control circuit 12
9. The comparison section 20 and the second output section 21 operate to confirm that the pulled out inner box 3 is the instructed inner box 3, and turn off the indicator light LED.

When the inner box 3 that is different from the instruction given by the indicator light LED is pulled out, the turn-off command signal is not output from the second output section 21, so the indicator light LED is not turned off.
An alarm such as a buzzer will be issued if necessary.

In this way, the device of the present invention does not have a push-button switch, and the confirmation work that should be performed by a push-button switch is automatically performed by the photo sensor 5 corresponding to the indicator light LED. A perfect correspondence is established between the tasks, there are no mistakes in the confirmation work, and reliable picking is guaranteed.
