The use of the pallet 1 itself is shared between the sender and receiver. Alternatively, in such goods storage facilities as warehouse facilities or goods-sending facilities, when the goods are sent to the receiver from the sender with the pallet 1, the bar code mounting device 7 to which a label with a bar code exclusive to the receiver on is affixed is attached to the pallet 1.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bar code attached to a pallet in storage facilities such as a manufacturing factory, a distribution center, a distribution center, a distribution center, etc., for individually recognizing the pallet and managing the load on the pallet. The present invention relates to a management method using pallet bar codes.

[0002]

2. Description of the Related Art Manufacturing factories, distribution centers, distribution centers, distribution centers, etc. have storage facilities such as automatic warehouses, flat warehouses, etc., and can individually recognize goods or pallets dedicated to goods transport at these places. Provide a bar code display to automatically recognize goods and pallets,
In many cases, various article management such as entry / exit management is performed.

[0003] For example, a bar code label indicating a pallet specific number is attached to the outer surface of an article case or a pallet dedicated to article transport managed in a warehouse, read with a bar code reader, and a product name corresponding to the pallet unique number. The information is registered in the computer in association with the load information data such as the shape and quantity (that is, the packing style), and based on the information, the entire article in the warehouse is managed through the computer and each terminal communicated by wireless or LAN. doing.

In a warehouse management system as shown in FIG. 7, a bar code reader 13 and a communication device 14 are provided on a forklift 12 for transporting a pallet P.
Information such as a pallet unique number read by the barcode reader 13 is sent to the management computer 10 via the relay station 9 connected to the warehouse or the like as a network. Management computer 10 and each relay station 9
Are connected via a distributor 10A.

[0005] The management computer 10 can perform predetermined processing such as updating of inventory management information, etc., based on information obtained from the forklift 12, or can instruct the forklift 12 for cargo handling work (in / out work). is there. this is,
When the article W is placed on the pallet P by the palletizer or an operator (not shown),
The pallet unique number and the load information (packing style) such as the article name, shape, and quantity of the article are stored. In particular, there is an information table in which the pallet unique number corresponds to the packing style such as the article name and quantity of the article on a one-to-one basis. Then, based on this information, inventory management and cargo handling work are instructed.

[0006] In addition, the following are specific examples of article management in storage facilities such as a manufacturing factory and a distribution center using the barcode of the pallet P. (A) Receiving management, receiving management (b) Pallet transport management (c) Loading location management in storage equipment (d) Inventory management, receiving / acquiring results management, order management (e) Order data inventory, allocation processing, receiving Payment management, assignment management (f) Creation and transmission of delivery instruction data (g) Delivery management, shipping management, inspection (h) Return management, accumulation management Therefore, pallet management in this specification refers to pallet management itself Alternatively, it means that any one of these is performed using the barcode of the pallet during the loading and unloading of the load, and this is also understood in the broadest sense.

[0007]

By the way, the bar code is displayed on the pallet and the pallet is automatically recognized as described above, in some cases for the sole purpose of either the source or the destination business establishment. In most cases, even if both barcodes are displayed on the pallet and both are rationalized, the barcode system itself differs for different companies, and the mounting position of the barcode display part is different. The fact is that there is virtually no common usability, differently.

Therefore, at present, when the palletized cargo is carried out from a storage facility such as a distribution center to the carry-in destination, the cargo is sent to the carry-in destination using a pallet with a barcode dedicated to the carry-in destination previously sent from the carry-in destination. At the time of unloading or unloading, the actual situation is that cargo is transshipped from a pallet with a barcode dedicated to storage equipment to a general transport pallet.

Similarly, when receiving the package from the transportation source, the transportation pallet on which the package has been loaded is transshipped to a pallet with a bar code dedicated to the storage facility, or the transportation source is previously provided with a bar code dedicated to the storage facility. The actual situation is that the pallets are sent, and the goods are carried in from the source by the pallets with the barcodes. After all, various types of standards such as JIS have been specified, and wooden flat pallets for integrated transportation (JIS Z 060) which are frequently used in the distribution industry
Although there are pallets for transportation such as 1) above, the bar code can be used on the pallet even though the pallet can be used in common with the transportation source and destination via a pallet rental company, etc. If rationalization is carried out in the management of goods such as installation and retrieval, the common use of pallets will be impeded,
Problems such as transshipment of loads occur.

The present invention has been made to solve the above-mentioned conventional problems. A bar code is provided on a pallet to store and retrieve goods and articles in storage facilities such as a manufacturing factory, a distribution center, a distribution center, and a distribution center. Even if the management is streamlined or automated, it is possible to maintain the common usability of pallets at the source, destination, etc., and to perform cumbersome operations such as transshipment of luggage when unloading or loading luggage. Management using pallet barcodes, which eliminates the need for pallet transport for the purpose of integrated transport and can maximize the labor-saving effects of pallet transport without halving, and can rationalize and automate storage facilities using barcodes. The aim is to provide a method.

.

That is, as shown in the schematic process schematic diagram of FIG. 1, at the transportation source that loads the product (load) into the distribution center,
The product 10 is stacked on an empty pallet 1 and loaded on a truck by a forklift or the like. The pallet 1 will be described in detail. As the pallet 1, various pallets can be used. Various pallets are also defined in JIS and can be preferably used in the present invention, but in this embodiment, a wooden flat pallet for integrated transportation is used in both sides or two sides or one side is used (JIS Z 060).
1) (hereinafter simply referred to as a pallet).

As shown in FIG. 2, the pallets 1 are provided at the sides and at the center between the sides.
And 4, and a plurality of decks which are arranged at predetermined intervals on the upper and lower surfaces of the respective beams 2, 3 and 4 so as to connect the respective beams 2, 3 and 4 and are connected to the respective beams 2, 3 and 4 And a board 5. The deck boards 5A and 5B, which are located on both outer sides of the deck board 5 and constitute the insertion ports 6 located between the side and center beams 2 and 4 and between the 3 and 4, respectively, are edge boards and Called.

The insertion port 6 is provided at the opposite side 2 of the pallet 1.
Direction. Each part of the pallet 1 will be described in accordance with pallet terms defined in the JIS standard. The deck board 5 is a plate constituting an upper deck serving as a loading surface of the pallet 1 and a lower deck serving as a grounding surface of the pallet 1. -Shaped member.

Digits 2, 3 and 4 are pallets 1
Is a member that joins and supports the deck board 5 over the entire length thereof and forms the insertion port 6. The insertion port 6 is an opening for inserting a finger or the like of a fork or a pallet truck. The pallet 1 is rented from a pallet company and is generally used everywhere. The product 10 is stacked on the pallet 1 and loaded on a truck by a forklift, a crane, a pallet truck or the like. In this case, the same product 10 is loaded on one pallet 1.

When a truck that has loaded a plurality of pallets 1 in which the products 10 are stacked on the pallets 1 and has left the transportation site arrives at a distribution center, the pallets 1 are unloaded from the trucks with the products 10 being loaded by a forklift. The forklift driver puts the pallets 1 on which the products 10 carried in from the outside are placed on the receiving conveyor according to the display on the on-site computer terminal. On this receiving conveyor, a bar code mounting device is set manually or by the side of the conveyor, and a bar code is mounted on each pallet 1 with the conveyed product 10 mounted thereon by using the mounting device. The attachment 7 is mounted. The computer terminal is connected to the management computer via a LAN. When the truck arrives, the truck arrival is input to the management computer, and the arrival information is listed on the computer terminal. When the user looks at the product 10 on the pallet 1 on which the pallet 7 is mounted and selects the corresponding package information displayed on the computer terminal, the package information (that is, the package form) of the pallet 1 is registered in the management computer. You. At the same time, the bar code 8A (see FIG. 2) of the pallet number displayed on the bar code attachment 7 of the pallet 1 is read by the bar code reader beside the storage conveyor, and the pallet number is transmitted to the management computer. Thereby, the pallet number and the load information are registered in association with each other. These bar code attachments 7
Is carried out while the pallet 1 is temporarily stopped or moving on the receiving conveyor.

In the case where only the product 10 is exceptionally carried in from the transport source, although not shown, the product 10 is placed on an empty pallet 1 prepared somewhat, and then
Is mounted on the pallet 1, the bar code attachment 7 provided with the bar code is mounted. Next, the bar code attachment 7 attached to the pallet 1 is shown in FIG.
This will be described in more detail with reference to FIG.

In these figures, the pallet bar code attachment 7 of the present embodiment is made of an elastic material, and has a pair of plate-like pieces 7A opposed to each other and a plate-like piece 7A connecting the two pieces 7A to each other. And a bar code label 8 as a bar code display portion is provided on a part of the outer surface of the substantially U-shaped forming member having the connecting portion 7B.
The pallet is held between the pair of pieces 7A by elastic force.

More specifically, the pallet bar code attachment 7 is formed by connecting a plate member made of an elastic material to a pair of opposing pieces 7A and connecting portions 7B connecting the two pieces 7A to each other.
And a bar code label 8 on which a bar code 8A is printed is attached to a part of the outer surface of the connecting portion 7B. The pallet bar code attachment 7 is detachably attached to the pallet 4 by means of a pair of pieces 7A, for example, by clamping the center 4 of the insertion port 6 of the pallet 1 from both sides with elastic force. Is done. In particular, when the attachment 7 is made of the spring steel, the girder 4 can be clamped from both sides by a strong spring force.

When freely attached to the beam 4, the connecting portion 7B of the fixture 7 is attached to the front of the beam 4 so that the bar code label 8 is located at the front position of the beam 4 facing forward. Has become. Furthermore, in such a fixture,
The distal end of each piece 7A is formed to be curved outward and serves as an insertion guide portion formed in a predetermined curved shape.
The insertability of the pallet into the beam can be improved, and the two pieces are bent at an angle of less than 90 degrees with respect to the connecting part, and the distance between the two pieces gradually increases from the bent part toward the tip. Since it is formed so as to be tapered, the elasticity of the material can be further utilized, and the state of attachment to the pallet can be stabilized.

The mounting device of the bar code attachment 7 is a robot arm which holds the bar code attachment 7 and presses a pair of pieces 7 A of the bar code attachment 7 toward the center beam 4 of the pallet 1. Can be configured. And
The pallet 1 temporarily stopped on the receiving conveyor manually or by the mounting device described above.
A pair of pieces 7A of the bar code attachment 7 is inserted into the above-mentioned beam 4 at the center of the pallet 1, and is mounted on the pallet 1 so as to sandwich the beam 4 by the elastic force of the pair of pieces 7A. As a result, automatic recognition (by a barcode reader or the like) based on the barcode 8A in a storage facility including a storage place or a warehouse and an associated article conveying means such as a conveyor becomes possible, and entry and exit from the automatic warehouse and the like are enabled. , Which is the basis of the management method using the barcode 8A of the pallet according to the present invention.

As described above, while moving the receiving conveyor,
When the pallet number (bar code 8A) displayed on the bar code attachment 7 of the pallet 1 is automatically read by the bar code reader and this pallet number information is transmitted to the management computer, the management computer sets the storage location to the storage location. An instruction is given to a control device for controlling article transport means such as a conveyor and a stacker crane, and the pallet is transported to a predetermined shelf of an automatic warehouse via a receiving conveyor and a stacker crane for temporary storage. The storage is sensed by a sensor provided on the storage shelf of the automatic warehouse and transmitted to the management computer via the control device of the article transport means. The management computer stores the pallet number, the package information (package style) and the storage location in association with each other.

The receiving conveyor is mainly constituted by an automatic roller conveyor or a chain conveyor (these conveyors are collectively referred to as a conveyor), and the pallet 1 is branched and assembled repeatedly at a predetermined location using the conveyor. Automatically transported to During the transport, the conveyor is also divided into blocks corresponding to the signal section so as to control the transfer of the pallet 1 as if the train were centrally controlled by the blockage management of the signal section to prevent rear-end collision. The more blocks are subdivided, the more pallets 1 are conveyed simultaneously. Operational information such as "presence / absence" of whether or not the pallet 1 exists on each block of the conveyor is detected by various sensors, and is sequentially communicated to the control device. The control device controls the entire article transporting means associated with the warehouse by adjusting the movement between adjacent conveyors based on the operation information.

By adopting the above method, there is no need to reload the palletized product 10 (load) delivered from the transport source to the distribution center to a pallet dedicated to the distribution center and carry it into an automatic warehouse or the like. This is effective for streamlining work and streamlining logistics. Specifically, receipt management, receipt management, pallet transport management, storage location management in storage equipment, inventory management, inventory management, order management, order data inventory, allocation processing, receipt and payment management, assignment management, One of these is performed, such as creation / transmission of delivery instruction data, delivery management, shipping management, inspection, return management, and accumulation management.

The pallet 1 on which the product 10 is mounted is temporarily stored as it is, and waits for unloading. After storage, a depalletizing operation and a picking operation are performed as necessary. When the stored pallet 1 is carried out from the distribution center to the outside, the barcode attachment 7 with the barcode label 8 is removed from the pallet 1 with bare hands or a removing machine.

In this case, the pallet 1 is loaded with a load.
Is stored once, the product 10 is moved on a pallet by a depalletizing operation, a picking operation, or the like, as needed, and the article management is performed. Therefore, (a) a case where the pallet is carried out of the distribution center to the outside in the same package as the package on the pallet 1 stored first, and (b) a picking operation is performed and the pallet 1 stored first.
The case where the pallet 1 is carried out of the distribution center to the outside in a form different from the above form, and (c) the products 10 of the pallet are carried out little by little by the depalletizing operation and the picking operation, and all the products 10 are brought down. The pallet 1 may be carried out of the distribution center to the outside.

First, (a) when the pallet 1 is carried out of the distribution center to the outside with the same package as the stored pallet 1 on the pallet 1, the pallet 1 is loaded from a predetermined shelf of the automatic warehouse by a stacker crane. It is transported to the delivery conveyor. On the delivery conveyor, first read the bar code 8A of the pallet number displayed on the bar code attachment 7 with a bar code reader, or read the pallet number displayed above the bar code 8A visually. Check 10. Next, in a state where the barcode attaching device 7 is transported to a position where the exclusive device for removing the barcode attaching device 7 is installed and stopped, the barcode attaching device 7 is attached to the pallet 1 using the device for removing the barcode attaching device or simply with bare hands. Remove the attached bar code attachment 7. As a result, the barcode 8A dedicated to the distribution center has been removed from the pallet 1, so that the pallet 1 has its uniqueness at the distribution center and the common usability of the pallet 1 has been restored. However, it can be used.

The pallet 1 from which the bar code attachment 7 has been removed is loaded on a truck with the product 10 placed thereon, and is carried out to the destination. At the destination, the pallet 1 is unloaded with the product 10 loaded from the truck to receive the load. The pallet 1 can be used in various ways depending on the circumstances of the destination. For example, the pallet 1 can be returned to a pallet company when the pallet 1 is empty after the product 10 is stored in a warehouse with the product 10 loaded thereon and all the products 10 are used. And store the product 10 only after receiving it and immediately return the empty pallet 1 to the pallet company, or place the product 10 or other luggage on the pallet 1 and transport it to another place. There is. In short, it is used as a normal transport pallet.

The pallet 1 with the (b) load on it
If the pallet 1 is taken out of the distribution center after being stored and the picking operation is performed and the pallet 1 is different from the stored pallet 1 on the pallet 1, the stored pallet 1 remains on the pallet 1 A pallet 1 is transported from a predetermined shelf of an automatic warehouse to a delivery conveyor by a stacker crane. On the delivery conveyor, first read the bar code 8A of the pallet number displayed on the bar code attachment 7 with a bar code reader, or read the pallet number displayed above the bar code 8A visually. Check 10. Next, the product 10 is conveyed to a picking place, and a part of the product 10 on the pallet 1 is lowered, or the product 10 of another pallet 1 is added.

The pallet 1 on which the picking operation is completed and on which a predetermined product 10 is placed is transported again to the storage location, where the pallet 1 is stored until the depalletizing operation, the picking operation, and the carrying out of the distribution center to the outside, and the like. There are cases where the picking operation is carried out of the distribution center to the outside without being transported to the storage location after the picking operation. Subsequent operations in the former case are no different from the handling of the initially stored pallet 1. In the latter case, the pallet 1 on which the picking operation is completed and the predetermined product 10 is placed
Then, the bar code attachment 7 attached to the pallet 1 is removed in a state where the bar code is conveyed to a predetermined position by the delivery conveyor and stopped, as described above. As a result, the barcode 8A dedicated to the distribution center has been removed from the pallet 1, so that the pallet 1 has its uniqueness at the distribution center and the common usability of the pallet 1 has been restored. However, it can be used. Pallet 1 from which barcode attachment 7 has been removed
In the same manner as described above, the product is loaded on a truck with the product 10 mounted thereon, carried out to the destination, and unloaded and received at the destination with the product 10 mounted thereon.

(C) After temporarily storing the pallet 1 with the load thereon, the products 10 of the pallet 1 are carried out little by little by a depalletizing operation, a depalletizing operation or a picking operation, and the products 10 are all unloaded. When unloading the pallet 1 from the distribution center to the outside,
The pallet 1 is conveyed from the predetermined shelf of the automatic warehouse to the delivery conveyor by the stacker crane as it is on the stored pallet 1, and the bar code of the pallet number displayed on the bar code attachment 7 on the delivery conveyor. 8A is read by a barcode reader, or the pallet number displayed above the barcode 8A is visually read, and after the outgoing product 10 is confirmed, the product is transported to a picking place. The product 10 is sorted to a predetermined destination by a depalletizing operation or a picking operation, and the product 10 is loaded on a truck and discharged to the destination.

The pallet 1 in which all the products 10 have been unloaded is conveyed to a predetermined position by the delivery conveyor and stopped, and the bar code attaching tool mounted on the pallet 1 7 is removed. As a result, the barcode 8A dedicated to the distribution center has been removed from the pallet 1, so that the pallet 1 has its uniqueness at the distribution center and the common usability of the pallet 1 has been restored. However, it can be used. Empty pallet 1 with barcode fixture 7 removed
When a predetermined number is collected, they are loaded on a truck or the like, returned to a pallet company, and reused.

As described above, in the present embodiment, when the pallet 1 on which the product 10 is loaded is loaded from outside the distribution center, or when the load carried only by the product 10 is transferred to the distribution center by the pallet 1, the product 10 is Since the bar code attachment 7 provided with the bar code 8A is mounted on the pallet 1 while being placed on the pallet 1, the pallet 1 is based on the bar code 8A at the distribution center including the storage location and the associated article transporting means such as a conveyor. Automatic recognition by a bar code reader or the like becomes possible, and is effectively used for managing the pallet 1 in the distribution center.

After storage, a depalletizing operation and a picking operation are performed as necessary, and when the pallet 1 loaded with a predetermined product 10 is carried out, or when the pallet 1 product 10 is carried out by a depalletizing operation or a picking operation, the product 10 is carried out. When unloading the pallet 1 from which all of the pallets 10 have been lowered to the outside, the bar code attachment 7 is removed from the pallet 1, so that the pallet 1 is not unique in the distribution center, and Pallet 1
The common usability of is restored, and it can be used anywhere.

Therefore, a general pallet such as a rental pallet can be used everywhere, and the labor-saving effect of pallet transport for the purpose of integrated transport can be maximized without being reduced by half. The code 8A can streamline or automate the distribution department such as a distribution center. In particular, when the pallet 1 on which the product 10 is loaded is loaded into the distribution center from the outside by a truck or the like, the bar code attachment 7 provided with the bar code 8A is mounted on the pallet 1 while the product 10 is loaded. Therefore, when carrying in, there is no need to reload the palletized product 10 delivered from the transport source to the distribution center to a pallet dedicated to the distribution center.

Further, a pallet on which the temporarily stored product 10 is placed is subjected to a picking operation as required, and when the pallet 1 on which a predetermined product 10 is loaded is carried out to the outside, the pallet 1 with the product 10 placed thereon is kept. Since the bar code attachment 7 is removed from the pallet, there is no need to transfer the product 10 from a pallet with a bar code unique to the distribution center to a general pallet for transportation when unloading, and thus the labor for the reloading is not required.

In addition, the loading of the pallet 1 on the conveyor or the removal of the pallet 1 from the conveyor requires the use of a transport machine such as a forklift or the like, and requires the intervention of humans. Since the pallet number is checked mechanically by the bar code 8A without visually checking the brand of the package, the burden of attention and labor is significantly reduced. In particular, when dealing with multiple varieties of cosmetics, daily necessities, and the like having similar appearances, the risk of erroneous entry and exit is greatly reduced. In the case of a wrong warehousing, credibility with the customer may develop, so easy identification occupies an important position in warehousing and management, and mechanical confirmation of the pallet number using the bar code 8A is very effective. is there.

The second embodiment described below is an example in which the management method using the bar code of the pallet according to the second aspect of the present invention is applied to a manufacturing department such as a factory for manufacturing cosmetics and drinking water. Yes, on a pallet, load a barcode attachment with a barcode attached with a barcode so that it can be seen from the outside with the elastic force of the barcode attachment, load the load, and store the pallet with the load placed, 6. The barcode mounting tool according to claim 5, wherein the barcode mounting tool is removed from the pallet when the loaded pallet is subsequently carried out to the outside, and the barcode mounting tool is provided on the pallet so that the barcode is visible from the outside. Is loaded with the elastic force of the bar code attachment, and the pallet is stored with the load placed thereon, and then when the unloaded pallet is carried out, the bar pallet is removed from the pallet. It is intended to include the manner according to claim 6 removing the fixture.

FIG. 4 shows a schematic process of temporarily storing a manufactured product 20 (load) in a manufacturing factory and then shipping the product 20. First, the rented from a pallet company. The bar code attachment 7 is mounted on the pallet 1. In this case, the pallets are put into a receiving conveyor mainly composed of an automatic roller conveyor or a chain conveyor one by one by a forklift. The bar code attachment 7 is attached to each pallet 1 manually or on a side of the conveyor by using the attachment device of the dedicated bar code attachment. That is, the barcode attachment 7
Is such that the pair of pieces 7A of the barcode attachment 7 is inserted into the above-mentioned beam 4 at the center of the pallet 1 temporarily stopped on the receiving conveyor, and the beam 4 is held by the elastic force of the pair of pieces 7A. And mounted on the pallet 1.

The pallet 1 to which the barcode attachment 7 is attached is conveyed to a palletizing (stacking) place by a receiving conveyor and temporarily stopped for palletizing operation. In the palletizing place, products 20 packed and packed by another conveyor or forklift are conveyed from a place where packing, packaging, etc. of the products 20 are performed, and a predetermined amount of the products 20 is transferred to the receiving conveyor. It is put on the empty pallet 1 above.

In this case, the computer terminal installed there sends the storage plan information of the day from the management computer and displays a list of loading work groups including product names, lot numbers, quantities, and the like. The operator places a predetermined amount of the product 20 on the pallet 1 according to the display. When the loading operation is completed, the operation is selected from the loading operation group displayed in the list. As a result, the package information (that is, package) of the pallet 1 is registered in the management computer. It is to be noted that the series of loading operations may be performed mechanically without manual operation.

In any case, when the completion information (load information) of the loading operation for one pallet is transmitted to the management computer, the pallet 1 on which the product 20 is loaded is conveyed to the storage place by the receiving conveyor. The pallet number (bar code 8) displayed on the bar code attachment 7 of the pallet 1
A) is automatically read by the barcode reader beside the receiving conveyor. Thereby, the pallet number and the load information are registered in association with each other.

When this pallet number information is transmitted to the management computer, the management computer instructs the storage device to a control device for controlling the article transport means such as a storage conveyor and a stacker crane, and transmits the information via the storage conveyor and the stacker crane. The pallets are transported to predetermined shelves in an automatic warehouse and temporarily stored. The storage is sensed by a sensor provided on the storage shelf of the automatic warehouse and transmitted to the management computer via the control device. The management computer stores the pallet number, the package information (package style) and the storage location in association with each other. The pallet on which the product 20 is placed is temporarily stored as it is, and waits for unloading.

After storage, as needed, receipt management, receipt management, pallet transport management, load location management in storage facilities, inventory management, receipt / delivery results management, order management, order data inventory, allocation processing, receiving Any of payment management, allocation management, creation / transmission of delivery instruction data, delivery management, shipping management, inspection, return management, and accumulation management is performed, and a depalletizing operation and a picking operation are performed as necessary. When the pallet 1 once stored is taken out of the factory, the bar code attachment 7 with the bar code label 8 is removed from the pallet 1 with bare hands or a removing machine. The procedure and steps are the same as those in the first embodiment, and the description thereof is omitted.

As described above, in the second embodiment, when the packed or packaged product 20 is conveyed on a pallet at a place where the product 20 is packed or packed in the same manufacturing plant, Since the product 20 is placed after the bar code attachment 7 provided with the code 8A is attached by the elastic force of the bar code attachment 7, the storage in the factory is made up of a storage location and an article transporting means such as a conveyor attached thereto. Automatic recognition based on the barcode 8A (by a barcode reader or the like) at the equipment becomes possible, which is effectively used for pallet management at a factory.

After storage, a depalletizing operation and a picking operation are performed if necessary. When the pallet 1 loaded with the predetermined product 20 is carried out, or the pallet product 20 is carried out little by little by the depalletizing operation and the picking operation. When unloading the pallet 1 in a state where all the loads are unloaded, the barcode attachment 7 is removed from the pallet 1, so that the pallet 1 is not unique in the factory, and The common usability of the pallets is restored, and they can be used anywhere.

Therefore, a general pallet such as a rental pallet can be used everywhere, and the labor-saving effect of pallet transport for the purpose of integrated transport can be maximized without being reduced by half. Rationalization and automation of storage equipment can be achieved by the code 8A. In particular, when a pallet on which the temporarily stored product 20 is placed is subjected to a picking operation as needed, and when the pallet 1 on which the predetermined product 20 is loaded is carried out, the bar code is removed from the pallet 1 with the product 20 still loaded. Since the fixture 7 is detached, it is not necessary to transpose the product 20 from a pallet with a barcode unique to the distribution center to a general transport pallet at the time of unloading, so that labor for transshipment is not required.

The third embodiment described below is an example in which the management method using bar codes of pallets according to claim 3 of the present invention is applied to a distribution center such as a distribution center, a distribution center, or a distribution center. When loading a load on the pallet from the transport source, a barcode attachment provided with a barcode dedicated to the destination so as to be visible from the outside at the source is attached to the pallet by the elastic force of the barcode attachment,
6. The loading destination, wherein the pallet is stored with the load thereon, and the bar code attachment is removed from the pallet when the loaded pallet is subsequently carried out.
According to the aspect described above, when carrying a load on the pallet from the transport source, the bar code mounting tool provided with the bar code dedicated to the loading destination so as to be visible from the outside at the transport source is mounted on the pallet by the elastic force of the bar code mounting tool. The pallet according to claim 6, wherein the pallet is stored in a state where the load is placed, and the barcode attachment is removed from the pallet when the pallet is unloaded afterwards. And aspects.

That is, as shown in the schematic process schematic diagram of FIG. 5, at the transfer source that loads the product 30 (load) to the distribution center that is the transfer destination, the product 30 is transferred from the transfer source using the pallet 1 rented from a pallet company. At the time of loading into the distribution center, the barcode attachment 7 provided with the barcode 8A dedicated to the distribution center previously sent from the distribution center is attached to the pallet 1 at the source. In this case, the bar code attachment 7 may be attached to the pallet 1 after the products 30 are stacked on the empty pallet 1, or the product 30 may be attached to the empty pallet 1 after the bar code attachment 7 is attached to the pallet 1. Pallet 1
You may put in. The bar code attachment 7 may be attached to the pallet 1 either manually or by means of a dedicated bar code attachment mounting device. In short, a pair of bar code attachments 7 is attached to the beam 4 at the center of the pallet 1. The piece 7A is inserted and attached to the pallet 1 so as to hold the beam 4 by the elastic force of the pair of pieces 7A.

The pallet 1 on which the barcode attachment 7 provided with the barcode 8A dedicated to the distribution center and the product 30 is placed is loaded on a truck by a forklift or the like. Thus, at the source,
The product 30 is carried into the distribution center on the pallet 1 provided with the bar code 8A dedicated to the distribution center without any modification to the general-purpose pallet simply by attaching the bar code attachment 7.

When a plurality of pallets 1 in which the products 30 are stacked on the pallets 1 are loaded and the truck comes out of the transportation center, the trucks arrive at the distribution center and are unloaded from the trucks together with the products 30 by the forklift. The forklift driver puts the products 30 carried in from the outside into the receiving conveyor one pallet at a time. Next, while moving to the receiving conveyor, the pallet number (bar code 8) displayed on the bar code attachment 7 of the pallet 1 is displayed.
A) is read by a handy type barcode reader or a fixed barcode reader.

As a result, automatic recognition by a bar code reader or the like based on the bar code 8A at a distribution center comprising a storage place, a warehouse and an article transporting means such as a conveyer, etc., becomes possible, so that entry, exit, storage management, etc. Can be used effectively. For subsequent procedures and steps,
Since there is no difference from the first embodiment, the description is omitted.

As described above, in the third embodiment, the bar code 8A dedicated to the distribution center is provided on the pallet 1 when the product 30 is loaded on the pallet 1 from the carrier outside the distribution center to the distribution center by truck or the like. Since the bar code attachment 7 is attached to the pallet 1 and is carried in and stored in the distribution center while the product 30 is placed on the pallet 1, transshipment of the product 30 is not required at the time of carrying in, and the storage location and the warehouse and the accompanying storage are required. Automatic recognition by a barcode reader or the like based on the barcode 8A at a distribution center comprising article transporting means such as a conveyor becomes possible, and is effectively used for pallet management in storage facilities.

After the storage, a picking operation is performed as necessary, and when the pallet 1 loaded with the predetermined product 30 is carried out, or the product 30 of the pallet 1 is carried out by the depalletizing operation or the picking operation, and the product 30 is completely removed. Since the bar code attachment 7 is removed from the pallet 1 when the pallet 1 in the lowered state is carried out, the uniqueness of the pallet 1 at the distribution center is eliminated and the pallet 1 Common usability is restored, and it can be used anywhere.
