2. Description of the Related Art The applicant of the present invention has previously integrated an electronic weighing apparatus and a rotating rack in which articles are stored. The electronic weighing apparatus controls the rotating rack. We have proposed an inventory management device that performs a loading / unloading operation, inventory management, and the like (for example, see the specification and drawings attached to the respective applications of Japanese Patent Application Nos. 1-2225548 and 1-284629). The inventory management device includes: first storage means for storing work reservation data including an article number, which is identification data of an article, and the number of articles issued or received, and a rotating rack for the article corresponding to the article number. And storage means for storing the storage position data (shelf number) indicating the storage position and the current stock quantity.

[0003] When a worker inputs work reservation data in advance and makes a reservation for entry / exit, and then instructs start of entry / exit work, the order of the reserved and sorted article numbers corresponds to these article numbers. The shelf number and the number of warehouses or the number of warehouses are read out and displayed on a display unit, and the rotating rack is driven based on the shelf number so that warehouse and warehouse work can be performed.

Further, recently, the above-described inventory management devices are connected in a plurality of chains, and connected to a parent machine or a computer for management, and the above-described operation is performed via the parent machine or a computer via the parent machine. There is an inventory management system configured to send reservation data. Then, the worker of each electronic weighing device performs a leaving work based on the work reservation data received by each electronic weighing device. In this unloading work, the parts indicated by the work reservation data are taken out from the storage position of the rotating rack by the specified number, and
This is performed by bagging, and the counting of parts is performed using the electronic weighing device as described above.

[0005]

In the above-described inventory management system in which a plurality of conventional inventory management devices are connected in a chain, the work reservation data is stored in each inventory management device that manages parts to be delivered. It is appropriately distributed to the electronic weighing devices and processed in each of the electronic weighing devices. For this reason, the time at which the work is completed varies depending on each inventory management device. Therefore, a worker who finishes work early processes a completely different job until the work of another worker finishes,

Next, when the operator sets the operation mode of a certain electronic weighing device 4 to the unloading operation mode and then presses, for example, the [NEXT] key of the operation unit 19, the CPU 31 causes the operation reservation data buffer E shown in FIG. Then, it is determined whether or not the read work reservation data is the lot end data D. If the read work reservation data is not the lot end data D, the CPU 31 displays a part code, a product name, a unit weight, a designated number, and the like on the dot display based on the read work reservation data (including the part data). After the display at 20, the shelf 12 of the rotating rack 9 is rotated based on the read shelf number data of the work reservation data, and the take-out position is displayed by the indicator light 13.

Therefore, the operator pulls out the tray 11 from the position where the indicator lamp 13 is turned on, and then takes out the parts from the tray 11 and takes the first scale 17 and the second scale 1.
8, or a process of placing parts on the third scale 16 and checking the number of the parts is repeated, and after taking out the indicated number of parts, for example, the operation unit 19 of the electronic weighing device 4

Reference numeral 26 updates the total data of the corresponding component code in the component data buffer of the RAM 30.

Next, the operator stores the picked-up parts and the delivery slip on which the part names and the numbers are printed in a storage bag, and then returns the tray 11 to its original position. Thereafter, in order to read the next work reservation data, for example, the [NEXT] key of the operation unit 19 of the electronic weighing device 4 is pressed. Hereinafter, the following parts are delivered to the next part. On the other hand, if the work reservation data read out from the work reservation data buffer E is the lot end data D, the CPU 31 displays on the dot display 20 that the lot is finished, and then the operator For example, the operation unit 19 of
[*] It is determined whether or not to print the shipping destination label based on whether or not the key is pressed. Then, when the operator presses, for example, the [*] key of the operation unit 19 of the electronic weighing device 4,
The shipping destination label is printed by the printing unit 36 and issued. Then, the above processing is performed for the next lot. The shipping destination label is used when sorting the delivered parts by destination. However, since the label is not directly related to the present invention, its detailed description is omitted. The outgoing work is completed by repeating the procedure described above. When the worker presses the [NEXT] key, the end of the outgoing work based on the work reservation data is notified by displaying the fact on the display unit 35.

Next, for example, in a certain electronic weighing device 4, a worker who has completed the unloading work processes a completely different job until another worker finishes the unloading work. An operation for grasping the processing status of the work in another electronic weighing device 4 to assist the unloading work will be described.
In this embodiment, the processing status of the work in each electronic weighing device 4 is not always stored in the RAM, HD, or FD in the management device 1 or the RAM or FD in the master 2, but is stored in each electronic weighing device 4. When there is a request for work processing status data from the device 4, the CPU of the management device 1
From the management device 1,

Next, the operation of the CPU of the management device 1 when receiving a signal requesting the work processing status data will be described with reference to the flowchart shown in FIG. In this embodiment, as described above, the work reservation data operator entered by operating the keyboard 7 of the management apparatus 1, each electronic weighing device 4 every _one to 4 _n of the management apparatus 1 shown in FIG. 6 The work reservation data files C _{1 to} C _n are sorted and stored for each lot in ascending order of shelf number data, and the CPU 26 of the slave unit management unit 3 of the master 2 has a work reservation data buffer of the RAM 30 to some extent. When it becomes empty, a transmission request for work reservation data is transmitted to the management device 1 via the signal line _5a .

Thus, the CPU 26 transmits the electronic weighing devices 4 ₁ to 4 transmitted from the management device 1 via the signal line 5 _a.
The work reservation data for each _n is received and temporarily stored in the work reservation data buffer of the RAM 30. Further, CPU 31 of the electronic weighing device 4 ₁ to 4 _n, if there is an empty Each work reservation data buffer E (see FIG. 7), the signal line 5
_It requests work reservation data from the slave unit management unit 3 of the master 2 via _b .

And it was collected requesting S _3K, the process proceeds to step SB3.

In step SB3, the number of unprocessed works S _2K and S _3K collected in the process in step SB2 and the number of unprocessed works S _1K in the management device stored in the corresponding work reservation data file C are added to obtain a total. After calculating the number of unprocessed work S _K , the process proceeds to step SB4. In step SB4, after writing the total number of unprocessed work S _K calculated in the process of step SB3 in the corresponding storage area of the work processing status data file (see FIG. 10) provided in the RAM or the like inside the management device 1. , Step S
Proceed to B5.

In step SB5, the value of the counter K is set to n
That is, it is determined whether or not the processing in steps SB2 to SB4 described above has been completed for all the electronic weighing devices 4 connected to this inventory management system. If the result of this determination is "NO", the control proceeds to step SB.
Proceed to 6. In step SB6, after the value of the counter K is incremented by 1, the process returns to step SB2.

On the other hand, if the result of the determination at step SB5 is "YES", that is, if the processing at steps SB2 to SB4 described above has been completed for all the electronic weighing devices 4 connected to this inventory management system, Proceed to step SB7. At step SB7, the work processing status data signal line 5 _a to the electronic weighing device 4 that has transmitted the signal requesting the slave unit managing unit 3 and the signal line 5 _b work process status data via the master 2 After transmitting the contents of the file, the series of operations is completed.

Thus, the C of the electronic weighing device 4 that has received the contents of the work processing status data file (step SA2).
The PU 31 drives the printing unit 36 to print the received contents on, for example, a receipt sheet as shown in FIG. 11 (step SA3). The number of unprocessed operations in the electronic weighing device that has requested the operation processing status data is also printed on the receipt paper. As described above, the worker who has completed the work early presses the key for instructing the printing of the work processing status data of the operation unit 19 of the electronic weighing device 4 to print the receipt paper on each of the current electronic weighing devices 4. Since the work processing status data is printed, the processing status of the work of another worker can be grasped in real time. Therefore, since the work end time of the other electronic weighing device 4 can be predicted, it is possible to process completely different work or to assist the work of the worker who takes the longest time until the work of the other worker is completed. , You can use your time effectively.

Although the embodiment of the present invention has been described in detail with reference to the drawings, the specific configuration is not limited to this embodiment, and a design change or the like may be made without departing from the gist of the present invention. The present invention is also included in the present invention. For example, in the above-described embodiment, as shown in FIG. 11, an example is shown in which only the machine number and the number of unprocessed operations are printed on the receipt paper. However, the present invention is not limited to this, and is shown in FIG. As described above, the number of reserved operations previously stored in the management device 1 may be printed on the receipt paper. Alternatively, the expected processing time may be printed on the receipt paper in place of the number of unprocessed operations or as shown in FIG. The expected processing time is calculated from the past performance data in the number of unprocessed work, and is stored in the management device 1 in advance.
Multiply by the average processing time per operation. Further, a timer for measuring the current time is provided inside the management device 1, and an expected end time is obtained by adding an expected processing time to the current time.
As shown in FIG. 2C, the expected end time may be printed on the receipt paper. In the example of FIG. 12C, the current time, that is, the time when the receipt paper is printed is 1
5:40.

Further, in the above-described embodiment, an example is shown in which only data relating to outgoing work is used as work reservation data. However, the present invention is not limited to this. Can be processed in the same way. Of course, the above data may be mixed, but in this case, it is necessary to print the number of unprocessed work for each data on the receipt paper.

Further, in the above-described embodiment, the management device 1 is connected to each electronic weighing device 4 via the slave unit management unit 3 of the master 2, and the work reservation data is stored in the management device 1.
The information is distributed and stored in the slave unit management unit 3 and each electronic weighing device 4. However, in a system that is simpler than the above inventory management system, the work reservation data for all the electronic weighing devices 4 is stored only in the management device 1 or only in the slave unit management unit 3, and this work reservation data is stored online and in real time. It is also conceivable to supply each electronic weighing device 4. In this case, the unprocessed work reservation data stored in the management device 1 or the slave unit management unit 3 becomes the number of unprocessed work, and thus the processing in step SB2 of the flowchart shown in FIG. 9 is not necessary.

Also in the above-described embodiment, it is conceivable that the slave unit management unit 3 stores the work processing status data file in the internal RAM in real time on-line and updates the stored contents. For example, the slave unit management unit 3 first receives the number of reservation work of each electronic weighing device 4 from the management device 1 and stores it in the internal RAM together with the work processing status data file. Every time the minute processing is completed, the numerical value of the number of reserved work stored in the RAM is decremented. Thereby, the number of reserved work currently stored in the RAM inside the slave unit management unit 3 becomes the number of unprocessed work. Then, when there is a transmission request for the number of unprocessed works from each electronic weighing device 4, the number of unprocessed works is transmitted to the requesting electronic weighing device 4.

Further, in the above-described embodiment, an example in which the number of unprocessed operations is printed on receipt paper is shown. However, the present invention is not limited to this, and the number of unprocessed operations is displayed on the dot display 20 of each electronic weighing device 4. It may be displayed or notified by voice. In addition, in the above-described embodiment, the example in which the work processing status in all the electronic weighing devices 4 is printed on the receipt paper has been described. However, the present invention is not limited to this.
The operator requesting the work processing status designates the number of the electronic weighing device 4 by the operation unit 19 of the electronic weighing device 4 and prints only the work processing status of the number on the receipt paper,
It may be displayed on the dot display 20 or notified by voice. For example, ten electronic weighing devices 4
In the inventory management system to which is connected, when two electronic weighing devices 4 are performing work, it is wasteful to output only the work processing status of these two electronic weighing devices 4. There is no.

[0048]

As described above, according to the present invention,
Since the worker who has finished the work early can grasp the work processing status in another electronic weighing device, for example,
By preferentially assisting the operator of the electronic weighing device having a large number of unprocessed operations, it is possible to efficiently and quickly carry out the parts retrieval operation and the like. Further, since the work end time in another electronic weighing device can be predicted based on the work processing status, the time can be effectively used during that time. Furthermore, since the worker can grasp the work processing status of another electronic weighing device by the electronic weighing device in charge at the time of completion of the work, the worker goes to another electronic weighing device and the management device. It is not necessary to interrupt the work in another electronic weighing device and check the work processing status.
