Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a warehousing management system suitable for use in warehousing management of a warehouse stocking parts and the like.

"Prior art" In a production line of a factory, it is necessary to efficiently and efficiently supply the parts necessary for production in order to prevent the operation stop and the decrease of the operation rate. Therefore, a warehouse for temporarily stocking necessary parts according to the production plan is required. In such a warehouse, parts are stored in accordance with a predetermined production plan, and therefore it is necessary to confirm at the time of storage what the stored parts are.

Therefore, conventionally, an identification number of a part to be stored (hereinafter referred to as a part number) is registered, and at the time of storage, the part number of the part is entered from a keyboard or the like, and this and the registered part number are registered. Receiving parts were recognized by collation.

"Problems to be Solved by the Invention" By the way, parts manufactured by a parts manufacturer are generally carried to a warehouse by a transportation means such as a truck, and then stored by a truck driver or an assistant. Therefore, the entry of the part number at the time of warehousing is performed by a truck driver who is unfamiliar with the parts. For this reason, a relatively large number of mistakes are made in the input of the part number, the number collation does not make sense, and there is a problem in that warehousing management is hindered.

The present invention has been made in view of the above circumstances,
An object of the present invention is to provide a warehousing management system capable of accurately recognizing the components to be stored and reliably storing only the components scheduled to be stored.

"Means for Solving the Problem" The warehousing management system of the present invention determines whether or not a set of slip numbers of at least one component is a subset of a set of at least one slip number stored in advance. Determining means to perform, opening and closing means for opening and closing the carry-in entrance of the warehouse, and controlling the opening and closing means to open the carry-in entrance when the judging means judges that it is a subset,
In this open state, when the switch means is set to the on state, the control means controls the opening / closing means to close the carry-in port.

[Operation] According to the above configuration, it is possible to determine whether or not the set of slip numbers of at least one part owned by the supplier of the parts is a subset of the set of at least one slip number stored in advance. If it is done and it is judged that it is a subset, the carry-in port is opened. Then, when the switch is pushed while the carry-in port is open, the carry-in port is closed.

Therefore, only the parts that are scheduled to be stored are reliably stored.

[Examples] Examples of the present invention will be described below with reference to the drawings. It should be noted that this embodiment is an example in which the present invention is used in a production line for automobile parts.

A: Structure of Embodiment Structure of Automatic Warehouse FIG. 2 is a perspective view showing the structure of the automatic warehouse 1 used in an embodiment of the present invention. In the figure, an automated warehouse 1 is composed of a three-dimensional automated warehouse 1a and a horizontal rotary automated warehouse 1b. The three-dimensional automated warehouse 1a has a large number of storage units arranged in a matrix, and a crane device that is movable in the horizontal and vertical directions enables loading and unloading of components in each storage unit. The three-dimensional automatic warehouse 1a is designed to handle relatively large parts, and these large parts are handled while being stored in a predetermined number in a bucket B (see FIG. 5). Reference numeral 3 denotes a carry-in port of a bucket, and the bucket 4 carried in from here is carried into a predetermined section by a crane device after sequentially passing through a storage lane 5 and a storage station. Reference numeral 6 denotes a stopper provided at the carry-in port 3 for allowing or disallowing the carrying-in of components. Figure 1 shows the situation near the carry-in entrance. The stopper 6 normally closes the carry-in port 3 in a raised state,
If the parts input by the shipping company at the time when the parts are transported are to be stored, they are lowered and the carry-in port 3 is opened. Then, when the stopper 6 is lowered, the switch 7 is pushed to raise the stopper 6 to close the carry-in port 3. As will be described later, whether or not the transported component is to be stored is determined by comparing the slip numbers.

Returning to FIG. 1, the above-described horizontal rotary automatic warehouse 1b has a large number of storage units that rotate in the horizontal direction, and these storage units constitute a swivel conveyor. In addition, the swiveling conveyor is configured in multiple stages, and further three multistage conveyors are provided. Then, the components are loaded into any of the storage units of any stage by a predetermined loading / unloading device,
It is possible to carry out. In addition, the horizontal rotary automatic warehouse 1b
Handles relatively small parts, and these small parts are carried on a pallet (not shown). Numeral 10 is a pallet carry-in entrance, and the pallet 10 carried in from here is carried into one of the storage sections by an entrance / exit device after sequentially passing through the warehousing lane 11 and the warehousing station.

Next, 20 and 21 are delivery preparation lanes for buckets and pallets, respectively, which carry the buckets delivered from the three-dimensional automated warehouse 1a and the pallets delivered from the horizontal rotary automated warehouse 1b, respectively. The shipping preparation lane 20 branches into shipping lanes 22, 23, and 24. These shipping lanes 22, 2
3 and 24 supply parts to the first, second and third manufacturing lines, respectively. The shipping preparation lane 21 is a shipping lane 25L,
It branches into 25R, 26L, 26R, 27L and 27R. These shipping lanes 25L and 25R supply parts to the first manufacturing line, shipping lanes 26L and 26R supply parts to the second manufacturing line, and shipping lanes 27L and 27R supply parts to the third manufacturing line. To do.
Further, 28 is an emergency delivery lane used when urgently unloading a single-part component, and 30 is a re-stocking lane used when the once-delivered part is again loaded into the warehouse.

Configuration of Control System Next, FIG. 3 is a block diagram showing an electrical configuration of the same embodiment. In the figure, reference numeral 40 is a host computer installed in the head office, which creates a production plan. The production plan is a plan for determining how many cars of which model will be manufactured by when. 41 is a parts table file managed by the host computer 40, and the parts table file 41 stores a list of parts required for each vehicle type. In this case, for each part, a unique part number and use target data indicating which vehicle model the part is used for are set. Therefore, the parts can be grouped for each vehicle type based on the usage target data, and the list of the part numbers thus grouped is stored in the parts table file 41. In addition, the host computer 40 creates order data for instructing each parts manufacturer to order parts based on the production plan. This ordering data has a one-to-one correspondence with the ordering slip, and is made up of data indicating the slip number, the part number, the quantity, the delivery date and time, the line in which the part is used, and the like. The slip number is unique to each slip, and the same number is not assigned.

A host computer 42 is installed in the factory and performs data communication with the host computer 40 at the head office. Through this data communication, the production plan, order data and parts list related to the factory are transferred. The transferred production plan is stored in the production plan file 43. The host computer 42 drives the slip issuing unit 44 to print out the order slip 45. This voucher is issued according to the ordering data transferred from the host computer 40. On the slip 45, a slip number, a part number, an ordering party, and the like are printed, and a bar code indicating the slip number is printed. Reference numeral 46 is a carry-in performance file, in which order data corresponding to the issued slip is stored. This accumulation is performed to calculate the payment amount to the parts manufacturer later.

On the other hand, the parts manufacturer has the handy terminal 48 shown in FIG. 4, and stores information about the parts to be delivered in the memory card MC using the handy terminal 48. This storage process is performed as follows.

First, the parts to be delivered are placed in buckets or pallets for handling. Then, as shown in FIG. 5, the bucket B (or pallet) is provided with a bar code label BL. The bar code printed on the bar code label BL indicates a serial number (hereinafter referred to as a container number) for identifying the packet and the pallet.
This barcode label BL is issued in advance and distributed to each component manufacturer. Also, in the parts maker, the bar code label BL distributed is attached in advance to a predetermined position of the bucket or pallet. Then, when packing the delivery, the barcode of the slip 45 is scanned by the pen scanner 48a, and the handy terminal 48 reads the slip number. When reading the slip number, the handy terminal 48 displays a message on the display unit 48b to read the container number. Therefore, the operator has the bar code label BL
Scan with the pen scanner 48a, and then handy terminal 4
Have 8 read the container number. Next, enter the number of parts stored in the container from the numeric keypad of the handy terminal 48, and press the "execute key". As a result, the slip number,
The container number and the number of containers are stored as one data set. Here, the order contents in the slip 45 are contents instructing the parts to be delivered and the total number thereof, but the bucket B (or pallet) cannot generally store the total number of orders. Therefore, usually, a plurality of buckets correspond to one slip number.

Further, one memory card MC is assigned to one transportation truck. Therefore, the operator of the parts maker performs the above-mentioned operation for all buckets (or pallets) to be loaded in one truck, and stores the data set including the container number, the slip number, and the number in the memory card MC for each bucket. .

Next, reference numeral 50 shown in FIG. 3 is a sub-host computer installed at the warehouse site, and performs data communication with the host computer 42. Under the control of the sub-host computer 50, a carry-in plan file 51, an assembly plan file 52, a component file 53, an inventory master file 54, and a warehouse status file 55 are provided. In the import plan file 51,
The host computer 42 transfers the carry-in scheduled data for one day. This scheduled delivery data is stored in the host computer 40
This is data extracted from the ordering data sent by the above regarding the parts to be carried into the warehouse.

Therefore, by looking at the contents of the carry-in plan file 51, it is possible to search for the part number of the part to be carried into the warehouse on that day and to confirm the relationship between the slip number and the part number.

A production plan for the warehouse is written in the assembly plan file 52. This writing is performed as follows. First, the host computer 42 extracts the data related to the warehouse from the data in the production plan file 43, and the extracted data is transferred to the sub-host 50,
It is written in the assembly plan file 52 by the sub-host 50. Further, the component file 53 stores a parts table list that stores the relationship between the parts handled by the warehouse and the vehicle type. This writing is performed by the host computer 42 extracting from the BOM list transferred from the host computer 40 that is relevant to the warehouse, and transferring this to the component BOM via the sub-host 50. The inventory master file 54 is a file that stores which parts and how many parts are in which places in the three-dimensional automatic warehouse 1a and the horizontal rotary automatic warehouse 1b described above. The warehouse status file 55 contains
It remembers how many parts there are in the warehouse. That is,
Data obtained by compressing the data in the inventory master file 54 (data obtained by removing the data in the storage location) is stored. A card reader 56 reads data in the memory card MC, and transfers the read data to the sub-host 50. As described above, various data is written in the memory card MC by the operator of the parts manufacturer.
After this writing, each bucket B is a memory card
Along with the MC, they are placed on a truck and transported to the loading section of the warehouse. Then, the memory card MC is set in the card reader 56 by the truck driver, so that the data can be read.

Next, 60 is a centralized controller that controls each part of the warehouse 1, and controls the crane device of the three-dimensional automatic warehouse 1a and the loading / unloading device of the horizontal rotary automatic warehouse 1b. Further, the centralized controller 60 performs control for moving the stopper up and down. In this case, the slip number of the data of the memory card MC read by the card reader 56 is the loading plan file 51.
When the sub-host computer 50 determines that it matches the slip number of the day stored in, the stopper 6 is lowered by the storage permission signal supplied from the computer 50 and the carry-in port 32 is opened. . Then, when the truck driver finishes carrying in the parts, when the driver pushes the switch 7, the centralized controller 60 raises the stopper 6 to close the transport port 32. in this way,
Only when the slip number of the data of the memory card MC brought by the truck driver matches the slip number of the day stored in advance in the carry-in plan file 51, the stopper 6 descends and the transfer port 32 is opened. Therefore, the parts having different slip numbers are not carried in.

Further, the centralized controller 60 controls running / stopping of the storage lanes 5 and 11, and reads the barcode of the barcode label BL by the barcode readers 63 and 64 arranged on the storage lanes 5 and 11, respectively. Has become. This reading is performed as follows. When the bucket B or pallet is placed on the storage lanes 5 and 11, the centralized controller 60 drives the storage lanes 5 and 11 to transport the bucket B (or pallet). Then, when the bucket B (or pallet) reaches a predetermined position, the bar code readers 63 and 64 cause the bar code label B
Scanning is performed on L, which causes the barcode to be read. Here, the barcode reader 63,64
Although the scanning area is fixed, the position where the bar code label BL is attached and the direction in which the bucket B (or pallet) is loaded into the storage lane are determined in advance so that the scanning can be performed without any trouble.

B: Operation of Embodiment Next, the operation of this embodiment with the above-described configuration will be described.

First, the host computer 40 transfers the production plan, the parts list and the slip data to the host computer 42. As a result, the host computer 42 controls the slip issuing unit 44 to issue a slip 45 according to the slip data, and the issued slip 45 is sent to the parts manufacturer. Further, the host computer 42 stores the correspondence between the slip number and the part number in a predetermined storage area, and further transfers it to the sub-host 50.

On the other hand, in the parts maker, the bar code label BL is attached to the pallet or the bucket B at a predetermined position in advance. Then, according to the sent slip, the corresponding parts are put in the bucket B. Next, using the handy terminal 48, the input processing of the slip number, the container number, and the number of pieces is performed for each bucket B, and after the input processing is completed, the memory card MC is removed from the handy terminal 48. After that, the bucket B is loaded on the truck and carried to the warehouse loading section. At this time, carry the memory card MC.

Then, at the time of loading into the warehouse, the truck driver inserts the memory card MC into the card reader 56. As a result, each data of the slip number, the container number, and the number in the memory card MC is transferred from the card reader 56 to the sub host 50.
In the sub-host 50, it is checked whether or not the transferred slip number matches the slip number of the day stored in the import plan file 51 of the day, and if they match, an import permission signal is sent to the central controller 60. Forward. When the carry-in permission signal is transferred to the centralized controller 60, the centralized controller 60 lowers the stopper 6 and opens the carry-in entrance 3.

Further, since the sub-host 50 stores the data in which the slip number and the part number are paired in the carry-in plan file 51, if the slip number is transferred from the card reader 56, the sub host 50 knows the corresponding part number. You can Further, since the container number and the quantity data are transferred from the card reader 56, it is possible to know which container contains which part and how many parts.

Next, when the loading port 3 of the automated warehouse 1 is opened, the truck driver sequentially loads the loaded buckets B into the loading lane 5
To The loaded bucket B is conveyed to a predetermined position by the storage lane 5, and its barcode label BL is read by the barcode reader 63. The read barcode is transferred to the sub host 50 via the centralized controller 60. As a result, the sub-host 50 can know the container number of the loaded bucket B. Also,
The sub-host 50 searches the data in the inventory master 54 to find an empty storage section of the three-dimensional automatic warehouse 1a, and supplies the position information to the centralized controller 60. Accordingly, the centralized controller 60 controls the crane device of the three-dimensional automatic warehouse 1a to store the bucket B in the empty storage section. Then, the sub-host 50 recognizes which part and how many parts are in the bucket B. Therefore, the position information of the storage section is added to this to create inventory data,
This inventory data is written in the inventory master file 54. As a result, the inventory master file 54 stores the position information, container number, part number, and quantity data of the newly stored bucket B as a set. Further, the sub-host 50 extracts the part number and the number data corresponding to the part number from the inventory master file 54, and writes them as a set in the inventory status file 55.

In the above-described loading process, the truck driver can load the bucket B in a fixed order. This is because no matter what order the buckets B are thrown in, the container number of the bucket B is identified by reading the barcode label BL, and the container number is checked by comparing this with the data stored in advance. This is because it is possible to know the relationship between the part number and the number data. And all buckets B
When the loading of the vehicle is completed, the truck driver pushes the switch 7 to notify the sub host 50 that the warehousing process is completed.
Upon receipt of the completion, the sub-host 50 transfers the carry-in completion signal to the centralized controller 60. As a result, the centralized controller 60 raises the stopper 6 and closes the carry-in port 3. In addition, the sub-host 50 determines whether or not the number of stored parts is as instructed by the slip. If the determination result is negative, it means that the bucket B has been forgotten to be loaded or unloaded, so a predetermined alarm is issued to alert the truck driver.

The part numbers and container numbers used in the above-described embodiments may include not only numerical values but also alphabetic characters and symbols, and may be composed only by alphabetical characters and symbols.
The point is that the code can identify the component and the container.

Further, in the above-described embodiment, the stopper 6 is provided only at the carry-in port 3 of the bucket, but it may be provided at the other pallet carry-in port 10.

Further, although the above-mentioned embodiment is an example of a production line for automobile parts, in the present invention, the goods to be carried into the warehouse are not limited to the parts, and other arbitrary goods can be managed.

[Advantages of the Invention] As described above, according to the goods receipt management system of the present invention, the slip number of the data of the memory card brought by the truck driver is stored in advance in the carry-in plan file. Only when it coincides with the above, the stopper of the carrying port is lowered and the same port is opened, so that the parts with different slip numbers are not carried in. That is,
An effect is obtained in which only the parts that are scheduled to be stored are reliably stored.
