[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic weighing device such as an electronic counting scale which measures the total weight of parts, calculates the number of the parts from the total weight and the unit weight, and displays the parts. Equipped with an automatic warehouse that automatically rotates the shelf on which the parts storage box is placed to a predetermined position and automatically removes the parts storage box from the shelf and returns it to the shelf. The present invention relates to an automatic warehouse system that controls and stores a variety of parts and manages inventory.

[0002]

2. Description of the Related Art In a conventional automatic warehouse system, for each part code, which is identification data of a part, together with the item name and unit weight of the part, storage position data (shelf number) indicating the storage position of the part in the automatic warehouse is stored. It is stored in advance in a storage unit inside the electronic scale device. In addition, in this type of automatic warehouse system, work reservation data (part codes of parts to be put in and put out and the number of puts in and out) are collected in advance in order to efficiently carry out the putting in and taking out work. Some are stored in the storage unit. Then, when the worker inputs the part code from the operation unit of the electronic weighing device or reads out the work reservation data, the item name, unit weight, etc. of the part are read out from the storage unit inside the electronic weighing device and displayed. It is displayed on the department and the storage position data is transmitted to the automated warehouse.

There are various types of automatic warehouses. In a certain type of automatic warehouse, a shelf on which a parts storage box storing the parts is placed is rotated to a predetermined position based on the storage position data. After that, the display is stopped at the outlet and the indicator lamp indicating the storage position is turned on. Therefore, the worker takes out the parts storage box from the shelf, then takes out the parts from the parts storage box, and counts the desired number with the electronic weighing device to perform the shipping operation, or counts with the electronic weighing device. It is possible to store a number of parts in the parts storage box and carry out the warehousing operation. For details of the above-mentioned technique, refer to, for example, Japanese Patent Application Laid-Open No. 4-58119.

[0004]

By the way, in the above-mentioned conventional automatic warehouse system, during the loading and unloading work, a component is taken out from the wrong component storage box, or a component is stored in the wrong component storage box. In this case, there is a shortage of necessary parts when using the delivered parts, which causes a serious problem, for example, that the production line stops or accurate inventory management cannot be performed. Problems like this
If the parts storage box is divided into multiple parts,

An outline of the processing of the CPU 8 and the worker in the case of carrying out the warehousing work based on the work reservation data in such a configuration will be described with reference to the processing diagrams shown in FIGS. First, it is assumed that the work reservation data described above is stored in advance in a reservation data file (not shown) that constitutes the RAM 10. For details of the reservation data file, refer to the above-mentioned Japanese Patent Laid-Open No. 4-58.
See Japanese Patent Publication No. 119.

In step SP1 shown in FIG. 5, the operator sets the operation mode of the electronic weighing device 1 to the leaving operation mode and then operates, for example, the [NEXT] key of the first operation section 17. As a result, the CPU 8 causes the step SP2.
Go to. In step SP2, the CPU 8 causes the RAM 10
After the work reservation data is read out from the reservation data file of, the process proceeds to step SP3.

[0023] At step SP3, CPU 8 based on the component code of the work reservation data read in step SP2, RAM 10 of the preset data file 10 _a
And aggregation data file 10 _b from the component code, product name, reads the component data of the unit weight, and the like, and it stores in the corresponding registers of the working area of the RAM 10, the component code, product name, unit weight, the display unit INF19 and instruction number It is displayed on the dot display 15 via. Further, the CPU 8 supplies the read shelf number data of the component data to the carousel 3 via the carousel INF 23.

As a result, the carousel 3 rotates the shelf on which the parts storage box 25 in which the parts are stored based on the shelf number data is rotated, and then stops at the outlet and sets the storage position. Notification is given by the display lamp. And
The carousel 9 is a CPU via the carousel INF23.
A signal indicating that the movement of the shelf is completed is supplied to 8. As a result, the CPU 8 proceeds to step SP4.

In step SP4, when the CPU 8 receives the signal, it displays it on the dot display 15 via the display unit INF19, for example, as shown in FIG. 7 (a). As a result, the worker proceeds to step SP5. In step SP5, the worker pulls out the component storage box 25 from the place where the indicator light is turned on, and then the component storage box 2 is connected to the bar code scanner 5 connected to the electronic weighing device 1.
The code data corresponding to the bar code of the bar code label 26 attached to the front surface of 5 is read. As a result, the barcode scanner 5 supplies the read code data to the CPU 8 via the scanner INF 27, and the CPU 8 proceeds to step SP6.

At step SP6, the CPU 8 determines that the code data supplied from the bar code scanner 5 is currently R
It is determined whether or not it matches the code data of the shelf number data stored in the predetermined register of the working area of the AM 10. If the result of this determination is "YES", the CPU 8 proceeds to step SP7 in FIG. In step SP7, the CPU 8 displays the dot display 15 on the display unit INF19 as shown in FIG. 7B, for example. As a result, the worker can
Go to P8.

At step SP8, when the operator needs to take out the component from the component storage box 25 and count it, the component is first scale 11 and second scale 1
2 or placed on the third scale 7. As a result, the selection circuit 13 selects any one of the first scale 11, the second scale 12, and the third scale 7 under the control of the CPU 8 and measures the weighing signal generated in the selected scale. Since it is supplied to the CPU 8 via the section INF14, the CPU 8 proceeds to step SP9.

At step SP9, the CPU 8 sends the weighing signal supplied via the weighing section INF14 and the RAM 10 to the weighing signal.
After calculating the number of parts from the unit weight stored in a predetermined register in the working area of the
It is displayed on the dot display 15 via 19. Thereby, the operator determines whether or not the number displayed on the dot display 15 in step SP9 matches the instruction number displayed on the dot display 15 in step SP3. If the number displayed on the dot display 15 does not match the designated number, the operator performs the step SP.
Return to step 8 and add or remove parts from the scale. And dot display 1
If the number displayed in 5 matches the designated number, the worker proceeds to step SP10. Also, step SP8
In, when it is not necessary to count the parts, the worker immediately proceeds to step SP10.

At step SP10, the operator operates, for example, the [*] key of the first operation section 17 of the electronic weighing device 1. As a result, the CPU 8 controls the printer 2 via the printer INF 22 to print the predetermined data such as the part number, the product name, and the number on the label to issue the product tag, and the RAM 8 stores the total data file 10 _b of the total data file 10 _b . After updating the totalized data of the corresponding component codes, the process proceeds to step SP11. Further, the worker stores the taken-out parts and the actual product slip in a storage bag, and then returns the parts storage box 25 to the original position.

At step SP11, the CPU 8 has no remaining work reservation data read at step SP2,
It is determined whether or not the delivery work has been completed. When the result of this determination is "YES", the processing is terminated, the fact is displayed on the dot display 15, and the series of processing is terminated.
On the other hand, if the determination result in step SP11 is "NO", that is, if the work reservation data read in step SP2 has a remainder and the warehousing work is not completed, C
The PU 8 displays on the dot display 15 that there is remaining work reservation data via the display unit INF19, and displays a request to the operator to operate the [NEXT] key, for example. As a result, the worker returns to step SP1 in FIG. 5 to read out the next work reservation data and, for example, [NEXT] of the first operation unit 17 of the electronic weighing device 1.
Operate the key. Hereinafter, the warehousing work is performed on the next part by the above procedure.

When the result of the determination in step SP6 of FIG. 5 is "NO", that is, the code data supplied from the bar code scanner 5 is currently stored in a predetermined register in the working area of the RAM 10 as a shelf number. If the data does not match the code data, the CPU 8
Proceeds to step SP12. In step SP12,
The CPU 8 displays on the dot display 15 via the display unit INF19, for example, as shown in FIG. 7 (c). As a result, the worker proceeds to step SP13.

At step SP13, the operator confirms whether or not the component storage box 25 has been taken out from the wrong shelf or whether the component storage box 25 placed on the designated shelf is correct. To do. Then, if an error is found by the confirmation work, after correcting the error, the worker returns to step SP5. Step SP5
Then, the operator causes the bar code scanner 5 to read the code data corresponding to the bar code of the bar code label 26 attached to the front surface of the correct component storage box 25 in which the error has been corrected. Since the subsequent processing is the same as the above-mentioned case, the description thereof will be omitted. On the other hand, if no error is found by the above confirmation work, it is considered that it is not a work error but a failure of the automatic warehouse system, or a mistake in setting part data or work reservation data.
The operator takes measures in that case. Since the warehousing work and the inventory confirmation work are almost the same as the warehousing work described above, the description thereof will be omitted.

As described above, according to the above-described embodiment, when the parts set in the electronic weighing device 1 do not match the parts to be put in and out, a warning to that effect is given. Various conventional problems are solved. Although the embodiment of the present invention has been described in detail above with reference to the drawings, the specific configuration is not limited to this embodiment, and there are design changes and the like within a range not departing from the gist of the present invention. Also included in the present invention.

For example, in one embodiment described above,
Although the bar code printed on the bar code label attached to the parts storage box 25 is shown as an example using a bar code corresponding to the shelf number data, the present invention is not limited to this, and a bar code corresponding to the part number data is used. Good. In the case of the shelf number data, a bar code label can be attached to the parts storage box 25 before setting the relationship between the parts number and the shelves number. Therefore, when the manufacturer of the automated warehouse system ships this system, the parts storage box 25 There is an advantage that a barcode label can be attached to. However, if the user sets the relationship between the part number and the shelf number and then stores the wrong part in the part storage box 25, it cannot be checked. On the other hand, when the bar code corresponding to the part number data is printed on the bar code label attached to the part storage box 25, the above problem does not occur, but the relationship between the part number and the shelf number is set. There is a disadvantage that the bar code label cannot be attached to the component storage box 25 until later.

Further, in the above-described embodiment, the example in which the bar code label is attached to the parts storage box 25 is shown, but the present invention is not limited to this, and the bar code is printed on the parts themselves.
Alternatively, a barcode label may be attached. By doing so, even if an incorrect component is stored in the component storage box 25, it is possible to check that the component set in the electronic weighing device 1 and the component to be put in and out do not match. However, since it is necessary to print a barcode or attach a barcode label to each part, it is troublesome. However, recently, a barcode having a relatively large volume is preprinted with a barcode or a barcode label is attached in advance for another purpose, so that the barcode may be diverted. Further, not only a bar code is attached to a component, but also a plate or the like having a barcode attached thereto may be stored in the component storage box 25 together with the component.

Further, in the above-described embodiment, the example in which the bar code corresponding to the shelf number data is optically read by the bar code scanner 5 is shown, but the present invention is not limited to this, and the shelf number data or the part number. A code corresponding to is attached to the parts storage box 25 or parts,
Any method or means capable of physically reading the code may be used. For example, shelf number data or OCR (optical character recognition) characters of the part number may be printed on the part storage box 25 or the part, or a strip-shaped magnetic stripe in which the shelf number data or the part number is magnetically written. You may attach it.

In addition, the bar code label is attached to the electronic scale device 1
It may be printed and issued by the printer 2 connected to the printer. By doing this, even if the barcode label becomes dirty and cannot be read by the barcode scanner 5 due to long-term use, a new barcode label can be issued on the spot. Further, in the above-described embodiment, an example in which the carousel 3 is used as the automatic warehouse has been shown, but the present invention is not limited to this and, for example, the specification and the drawings attached to the application of Japanese Patent Application No. 4-320998. Automatic unloading described in
A carry-in type automatic warehouse (see FIG. 1) may be used. In the case of this type of automated warehouse, multiple parts storage boxes are placed on the conveyor in the order of the work reservation data, but since the parts storage box to be worked next is not indicated by the indicator lamp etc. like a rotating rack, It is easy to cause a mismatch between the set part code part and the part that actually goes in and out,
By applying the present invention, it is possible to effectively prevent the above mismatch.

[0038]

As described above, according to the present invention,
If the part of the part data set in the device and the part that the worker is actually trying to process do not match, a warning to that effect is issued, so the wrong part can be sent out,
Alternatively, there is no possibility that parts will be stored in the wrong shelf. Therefore, the inconvenience that the inventory management cannot be performed accurately because the necessary parts are insufficient or the inventory data does not match the actual inventory quantity is solved.
