And in the shelf structure shown in FIG. 5, the display device 11 as shown in FIG. 6 is individually provided corresponding to the mounting position of the storage box 5.

The display device 11 displays a picking quantity based on a quantity signal supplied from a control unit composed of a personal computer or the like, and is composed of a reset switch 12 and an LED for clearing the quantity display on the substrate 10. Three-digit display units 13a, 13b, 13c,
Further, the address number of the display device 11, that is, the display device 1
The DIP switch 15 is used to set a number for identifying the mounting position of 1. The display device 13
The numbers a to 13c are not limited to three digits. Also, the DIP switch 15 is a switch 1 that has been binarized to 1, 2, 4, and 8.
Although it is composed of 5a, 15b, 15c and 15d, it may be composed of 8 digits if necessary. Display 13a
.About.13c, and the number of digits of the switches 15a to 15d are appropriately set depending on the number of storage boxes 5 and the number of booths.

In the picking operation, the belt conveyor 3 conveys the container 2 in the direction of arrow A. At this time, the product 6 may be loaded in the container 2 on the upstream side, and some containers 2 may be conveyed in an empty state as shown at the left end. When the container 2 is conveyed, the display device 11 corresponding to the storage box 5 or the booth displays the numbers in synchronization with this, and the picker picks the designated number of products and installs them on the display device 11. Press the reset switch 12. Next, the picked product is put into the container 4 to complete a series of picking operations.

When the sorting work is performed in this manner, for example, when the position of the left storage box 5 in the upper part of FIG. 5 is set to n, if the address of the display device 11 is not set to n, the original address is set. The picking number shown for the number n of products is displayed at the position of the other storage box 5, and accurate picking cannot be performed. Therefore, when the product shelf 4 is installed, when the arrangement of the products is changed, etc., the dip switch 15 is operated to set the address of the display device 11. The set address is transmitted to the control unit, that is, the host computer via a data bus (not shown), and stored in a predetermined memory circuit.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of a display device to which the present invention is applied will be described below with reference to FIGS. 1 is a circuit diagram showing the configuration of the display device, and FIG. 2 is a flowchart showing the address setting method of the display device. In describing the embodiment, FIG. 5 referred to in the description of the conventional example is referred to as appropriate. The display device 11 in this embodiment is provided with three display portions 13a, 13b, 13c arranged side by side as shown in the lower part of FIG. 1 so as to display a three-digit number.
Further, a reset switch 12 corresponding to the first switch is provided on the right side of the substrate 10, and is configured to clear the numbers, notify the control section, and set the address of the display device 11. The display device 11 is provided with a control unit 21 for displaying the number of pickings, clearing, and setting addresses by the display units 13a to 13c.

Next, the main structure of the control unit 21 will be described. The control unit 21 has a control circuit 22 and a memory circuit 23 each composed of a CPU, a decoder 25 and a switching circuit 2.
It is composed of 6 and the like. The control circuit 22 is connected via a data bus to a control unit that comprehensively controls picking work and address setting, for example, a personal computer provided for each predetermined picking work unit so that data can be exchanged. The display signal obtained from the control circuit 22 is a BCD (binary coded decimal), and each of the display units 13a to 13c of the display device 11 is composed of seven segments. And each segment is a light emitting diode D
1 to D7, the decoder 2 for converting the BCD display signal into the seven-ary drive signals V1 to V7.
5 are provided.

The reset switch 12 has two functions of clearing the displayed picking number and setting an address. However, since the reset switch 12 merely generates a contact signal, when it is turned on, two types of operations, clear and address setting, cannot be performed unless the control circuit 22 identifies it. Therefore, in the present embodiment, the switching circuit 26 is provided so that the terminals T1 and T2 having different I / O ports at the time of clearing and at the time of address setting are provided.
The contact signal is supplied to 2. Although the switching circuit 26 may be incorporated in the control circuit 22, it is separately shown in FIG. 1 for convenience of description. In this embodiment, three-digit display parts 13a to 13c are provided,
Since the circuit configuration of each display unit is the same, FIG. 1 illustrates the circuit configuration of the display unit 13c. The resistors R1 to R7 are for adjusting the current of the light emitting diodes D1 to D7, and the respective light emitting diodes D1 to D7 are arranged in the display unit 13c shown in the lower part of the figure as shown in the figure to display the numbers 0 to 9. It is like this.

Next, the operation of the display device 11 will be described in relation to the picking work. Prior to picking, data relating to the quantity to be picked (hereinafter referred to as a picking signal for convenience of description) is input to the control circuit 22, and the accepted picking signal is stored in a predetermined address of the memory circuit 23. Next, the control circuit 22 reads the picking signal from the memory circuit 23 and supplies it to the decoder 25. The decoder 25 performs conversion from BCD to 7-ary, but since a truth table and the like regarding this conversion are known to those skilled in the art, illustration and description thereof will be omitted. When the numeral 5 is displayed by the output of the decoder 25, the display unit 13
For c, the light emitting diodes D1, D6, D7, D3, D
Current flows through 4. Also, when displaying the number 12,
For the display unit 13b, the light emitting diodes D2 and D3 are energized, and for the display unit 13c, the light emitting diodes D1 and D3.
2, D7, D5 and D4 are energized.

The picker 8 picks the product 6 on which the numeral 5 is displayed as described with reference to FIG. 5, then presses the reset switch 12 and then inserts it into the container 2. Then, the operation shifts to another picking operation, and the reset switch 12 is operated after the picking. In this way, the products based on the displayed picking number are sequentially picked, and a series of sorting work is completed. By the way, when the picking work is performed as described above, if the display device 11 and the storage box 5 do not match, that is, the display device 11
It is easy to understand that if the address setting is wrong, picking mistakes frequently occur. For this reason, in the present embodiment, the reset switch 12 that was originally used for clearing numbers is used to configure the address of the display device 11 easily and accurately.

An address setting method for the display device 11 will be described below. The address setting described below is performed as needed when a new picking facility is installed, a product shelf is added, or the storage position of the product is changed. When the address is set, the host computer constituting the control unit issues an address setting instruction to the control circuit 22 as shown in step S1 of FIG.
The display device 11 that has received the address setting instruction, that is, the control circuit 22, displays the display unit 13a to the display unit 13a, as shown in step S2.
Adr is displayed on 13c to allow a person who sets an address, for example, a picker to recognize that the address setting is to be performed.
Next, as shown in step S3, the address data is transmitted to the control circuit 22, and as a result, as shown in step S4, the numbers are displayed in a blinking state on the display portions 13a to 13c. The person who sets the address confirms the blinking of the number and presses the reset switch 12 to issue a memory instruction to the control circuit 22. At this time, the switching circuit 26 operates as follows.

When the address setting instruction signal is transmitted, the gate signal Vg generated from the control circuit 22 changes in level from low level to high level, for example. As a result, the address setting gate circuit G2 is turned on, and step S
As shown in FIG. 5, by turning on the reset switch 12, the terminal T1 of the control circuit 22 is grounded via the resistor R0, and this becomes the address setting signal. The control circuit 22 is
As shown in step S6, the fact that the transmitted address is set in the corresponding display device 11 is transmitted to the control unit, that is, the host computer. When the address setting is performed as described above and the address setting result is transmitted to the host computer, the host computer supplies an end instruction to the display device 11 and the address is stored in the memory circuit 28 via the data bus 27. The setting operation ends. In addition,
The memory circuit 28 may be shared with the memory circuit 23 provided for quantity display and control, but it is shown separately for convenience of description. An EEPROM that can electrically store and erase information is applied to the memory circuits 23 and 28.

When the end instruction is transmitted from the host computer to the display device 11, the gate signal Vg changes in level from high level to low level, and the gate circuit G2 is turned off. Therefore, even if the reset switch 12 is turned on, the address setting signal is not supplied to the control circuit 22. On the other hand, the output terminal of the phase inversion circuit 29 changes from low level to high level, and the reset gate circuit G1
Turns on. Therefore, after picking as described above, by operating the reset switch 12 to turn on, a contact signal is supplied to the terminal T2 of the control circuit 22 and the display as described above and the transmission to the host computer are performed. Will be done.

As described above, according to the address setting method of the present embodiment, the address data supplied from the host computer can be visually checked and the reset switch 12 can be operated to easily and accurately set the address. Settings are made. This address setting is performed by a large number of display devices 11.
Therefore, when the picking equipment 1 is newly installed or when the arrangement is largely changed, the address setting can be efficiently and accurately performed. Moreover, it is not necessary to provide an operating part for setting the address, and the reset switch 1 for clearing the quantity display is provided.
Since it can be carried out with the aid of No. 2, it is possible to reduce the number of parts, the cost, and the operation.

Next, a second embodiment of the present invention will be described with reference to FIGS. The difference between this embodiment and the first embodiment is that the display device 11 is configured so that addresses can be set individually. Therefore,
The parts that perform the same operations as those of the first embodiment are designated by the same reference numerals and the description thereof will be omitted. In addition to the reset switch 12, the AUX switch 14 is provided on the substrate 10 of the display device 11.
(Hereinafter, referred to as an auxiliary switch) is provided, and further, a mode switching circuit 31 for switching the operation between the address setting operation and the normal operation is provided. Mode switching circuit 31
Is composed of an AND circuit 32 and switch circuits 33 and 34, and the switch circuits 33 and 34 can be switched as indicated by a solid line and a dotted line in accordance with the level change of the gate signal Vg. The reset switch 12
The switch circuits of the auxiliary switch 14 and the auxiliary switch 14 are indicated by 12a and 14a in the upper right part of FIG. 3 for convenience of illustration.
That is, when the reset switch 12 is pressed, the switch circuit 12a shown on the upper right side is turned on, and the auxiliary switch 14 is turned on.
When is pressed, the switch 14a shown on the upper right is turned on.
Regarding the memory circuit 28, the memory circuit 2 described above is used.
Although 3 may be used, it is particularly shown for address setting. The memory circuit 28 is an EEPROM that can electrically store and erase data.

Next, the address setting operation of the display device 11 will be described. When setting the address, as shown in step S11 of FIG. 4, the reset switch 12 and the auxiliary switch 14 are simultaneously pressed to turn on, and the switch is turned on for a preset time, for example, about 3 seconds.
As a result, the address setting signal is supplied to the terminal T13 of the control circuit 22 via the AND circuit 32, the control circuit 22 is switched from the normal picking number display operation to the address setting operation, and the gate signal Vg is changed from low level, for example. Change the level to high level. Switch circuits 33, 3
4 is switched and connected from the state shown by the dotted line in FIG. 3 to the state shown by the solid line. Further, in synchronization with the switching to the address setting operation, the display units 13a to 13c display the step S1.
As shown in 2, the current address number is displayed. Next, a new address is set. There are two types of new addresses, a higher address and a lower address with respect to the current address, and the setting method differs depending on the upper and lower addresses.

If the current address is 10 and the newly set address is 11 or more, the higher address is set by adding to the current address, and if 9 or less, the higher address is subtracted from the current address. Lower address setting is performed. Therefore, when setting a new address,
As shown in step S13, it is confirmed whether the address to be newly set is higher or lower than the current address. If it is lower, the reset switch 12 is operated to perform subtraction as shown in step S14. In the case of, the auxiliary switch 14 is operated to perform addition as shown in step S15. In the state where the address setting is switched, the switch circuits 33 and 34 are switched as shown by the solid line, and therefore when the reset switch 12 is operated, the terminal T11 of the control circuit 22 is sensitive and the other terminals T12 to T14.
Does not respond. Then, each time the reset switch 12 is operated once, a subtraction of 1 is performed, and if the new address is 3, the reset switch 12 is operated 7 times and set to 3.

On the other hand, in the case of higher rank, the auxiliary switch 14 is operated. In this case, only the terminal T14 of the control circuit 22 is responsive to the other terminals T11 to T1 via the switch circuit 33.
3 is not sensitive. Then, each time the auxiliary switch 14 is operated once, 1 is added, and if the new address is 13, the auxiliary switch 14 is operated three times and set to 13. After setting a new address for either the high order or the low order in this way, the new address is stored in the memory circuit 28 as shown in step S16. This operation is performed by operating the reset switch 12 and the auxiliary switch 14 at the same time, for example, for 1 second. As a result, the new address that has been displayed until then is erased, and at the same time, the gate signal Vg changes in level from high level to low level,
The switch circuits 33 and 34 are switched to the circuits shown by the dotted lines, and the original state, that is, the state in which the picking number can be displayed is restored. After the picking is completed, the reset switch 12 is operated to clear the displayed picking number. However, when the reset switch 12 is operated independently, only the terminal T12 of the control circuit 22 is sensitive to the reset operation. Is done.

As described above, in the display device 11 of this embodiment, the address can be set independently by a simple operation of operating the reset switch 12 or the auxiliary switch 14 in the display device 11. . Therefore, it is very convenient when the storage position of the product is partially changed or when the product is partially changed. Moreover, the address setting is 1 while watching the numbers that actually change.
Since it can be performed by the 0-advance method, setting mistakes can be prevented.

[0026]

As described above, the display device and the address setting method of the display device according to the present invention include a display unit for displaying the number of picked products and a control circuit for controlling the display on the display unit. A first display such as a reset switch or the like originally used for clearing the picking number is displayed after the control unit switches the control circuit to the address setting by issuing an address setting instruction from the control unit. While the address data displayed by operating the switch is stored in the memory circuit via the control circuit, the control unit is notified and the address is set. Therefore, in the display device, the address of the corresponding display device can be set only by operating the first switch while observing the address data transmitted from the control unit, and the address setting error can be prevented. Also, since the address setting of each display device can be controlled by the control unit,
Addresses can be efficiently set for a large number of display devices, and work can be simplified and work time can be shortened when picking equipment is newly installed or when layout is changed significantly.

And a mode switching circuit. According to this display device, an address can be set on each display device side and the control unit can be notified, so that the address can be easily set when the storage position of the product is changed to a small scale. Moreover, since the address can be set by operating the two switches while actually viewing the numbers, it is possible to reduce the address setting error.
