Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is used as various physical distribution systems. In particular, a pallet flow rack line or the like is used so that picking (delivery) can be performed from the side surface side, and first-in first-out The present invention relates to a first-in first-out stocker device that realizes an efficient picking function that is compatible with various products.

[0002]

2. Description of the Related Art FIGS. 14 and 15 are views showing a conventional example. In FIGS. 14 and 15, 1 is a fluidized rack (flow rack),
2 is a shelf board, 3 is a case, 5 is a first-in first-out stocker device, 10 is a delivery port, 11 is a pallet flow rack line, 12 is a pallet, and 13 is a delivery port.

§1: Description of Conventional Example 1 ... See FIG. 14 FIG. 14 is an explanatory view of Conventional Example 1, in which FIG. 14 is a front view of a fluidized shelf and FIG.

Prior art example 1 is an example of a fluidized rack (flow rack) in which products are first-in first-out using an inclined shelf plate. As shown, the fluidized shelf 1 includes a plurality of inclined shelf boards 2
Each shelf 2 has a plurality of cases 3
Is configured to be mounted.

[0005] Each of the cases 3 is for accommodating pieces of products (in units of pieces), and each case 3 can be put into a hand to take out an internal product.

In this case, the shelf plate 2 is mounted so that the front side (front side) of the fluidized shelf 1 is low and the back side (rear side) thereof is high, thus forming an inclined shelf. A plurality of cases 3 are mounted on the inclined shelf board 2 as described above. These cases 3 are replenished (first inserted) from the back side of the fluidized shelf 1 and picked from the front side (front side) ( It is configured so that it can be put out (first out).

The fluidized shelf 1 as described above is suitable for picking on a piece unit basis (individual unit), and is not suitable for picking on a case unit basis. For example, in order to perform piece-based picking, the case 3 is not moved, and piece-based picking is performed from any case 3.

When the products in the case 3 are lost by picking, the products are replenished from the back side without moving the case 3. In such piece-based picking, since the case 3 does not move, it is possible to manually perform piece-based picking.

In addition, the first-in first-out operation is performed as follows in case-by-case picking. For example, a plurality of cases 3 are arranged as shown, and each case 3 has a
It is assumed that numbers such as 1, a2, a3, b1, b2, b3 are attached.

In this state, for example, when the case b1 is picked, the case b1 disappears. Therefore, after the picking work is completed, the case b2 is moved to the position where the case b1 was, and the case b3 is moved to the position where the case b2 was. Is moved, and another case is newly replenished (stored) at the position where the case b3 was located. By this processing, products can be put in first in first out.

As described above, there is almost no problem when picking the case in the front row on the picking work area side, but when picking other cases, troublesome work is required. For example, to pick the case b2, the case b1 is once taken out, and then the case b is removed.
2 is pulled out to the front and the case b2 is picked. At this time, the case disappears at the position where the cases b1 and b2 were.

Therefore, after the picking work is completed, the case b
1 is returned to the original position again, the case b3 is moved to the position where the case b2 was present, and another position is newly added to the position where the case b3 was present.

To pick the case b3,
After taking out the cases b1 and b2 once, the case b
3 is pulled out to the front and the case b3 is picked. At this time, the case disappears at the position where the cases b1, b2, b3 were. Therefore, after the picking work is completed, case b
1, b2 are returned to the original positions again, and another case is newly replenished (stored) at the position where the case b3 was.

§2: Description of Conventional Example 2 ... See FIG. 15 FIG. 15 is an explanatory view of Conventional Example 2, FIG. A is a schematic configuration diagram of the apparatus, and FIG.

Conventional example 2 is an example of a first-in first-out stocker device using a pallet flow rack line. This device is an example of a device suitable for handling a large amount of the same product (for example, handling products such as beer).

As shown in the figure, the first-in first-out stocker device 5 is equipped with a large number of pallet flow rack lines 11 and has a three-story structure. A part of the first-in first-out stocker device (for example, only the first floor) is shown as a plane as shown in FIG.

That is, as shown in FIG. B, the pallet flow rack lines 11 of the line A, the line B, and the line C are arranged side by side so that their side surfaces are in contact with each other. In this case, one end of the pallet flow rack line 11 is the entrance 13 and the other end is the exit 10.
It has become.

The storage port 13 side is a storage work area, and the storage port 10 side is a picking work area. In addition, the pallet flow rack line 1
The side surface of 1 is a work prohibited area in which work such as picking is prohibited.

In each of the pallet flow rack lines 11, for example, there are eight pallets 12, and as shown in the drawing, from the picking work area 15 side, pallets # 1,
It is assumed that palette # 2, palette # 3, ... Palette # 8 are arranged in that order.

In this case, receipt and picking (delivery)
Is carried out on a pallet basis, but storage is possible only at the location of pallet # 8, and picking is done on pallet # 1.
This is possible only at the location. Since the side surface side of the pallet flow rack line 11 is the work prohibited area as described above, it is not possible to store or leave from this portion.

For example, when the pallet # 1 is picked in the picking work area of the line A, there is no pallet at the location of the pallet # 1. At this time, the pallet # 2 to the pallet # 8 are sequentially moved by the carrying device in the direction of the arrow shown in the drawing, and the pallet 12 is packed in the picking work area side.

As described above, the next picking is performed while sequentially moving the pallets picked up in the picking work area in the direction of the arrow in the drawing, and the pallets 12 are sequentially loaded from the warehousing work area to carry out the first-in first-out operation. .

In the above-mentioned first-in first-out stocker device,
When handling a large quantity of the same product, picking work can be done efficiently by first in first out. However, since the number of pallets is large, a large number of pallet flow rack lines are lined up, and the picking work area (front for picking) is narrow, only pallet-based picking is possible.

Line A, line B, and line C are
This is to store and store only the same product, and it is necessary to operate only when handling a large number of specific products.

[0025]

The above-mentioned prior art has the following problems. (1): In the fluidized shelf of Conventional Example 1, when the number of cases is small, it is possible to efficiently perform picking work in piece units (individual units), but when the number of cases is large, even picking in piece units reaches the back of the shelf. The workability of picking deteriorates because the user puts his / her hand in the picking.

Further, in case of picking work in units of cases, the picking work is troublesome because the case is often taken in and out. In particular, as the shelf becomes longer and the number of cases increases, the number of cases to be taken in and out also increases, and picking in case units becomes a very troublesome and time-consuming operation.

For example, there is no problem in picking the case in the front row, but to pick other cases (cases arranged inside), the case in front of the case to be picked is once taken out to the outside. It is necessary to pick up from the case, and after picking, the case that has been taken out again needs to be returned to the original position, and the picking work is very troublesome and takes time and effort.

Therefore, the efficiency of the picking operation on a case-by-case basis is low. In particular, if the case is large and the number of cases is large, picking is substantially impossible. (2): In the first-in first-out stocker device of Conventional Example 2, when a large amount of the same product is handled, the picking work can be performed in order in the picking work area, so that the picking work can be performed efficiently.

However, in this apparatus, warehousing is performed from the warehousing work area on one end side of the pallet flow rack line, and picking can be performed only from the narrow picking work area side on the other end side of the pallet flow rack line. Therefore, it is not possible to pick pieces (pieces) individually, and only picks pallets.
Low degree of picking freedom.

(3): In the apparatus of Conventional Example 2, each line (line A,
(B, C, etc.) is for storing and storing only the same product, and it is necessary to perform the operation limited to the case where a large number of products are handled as a specific product.

That is, a large number of pallet flow rack lines are lined up, and it is necessary to perform picking work in a narrow picking work area while sequentially moving the pallets received from the warehousing work area to the picking work area side for each line. I have a lot of different products,
When picking an arbitrary product, picking cannot be performed.

(4): In the first-in first-out stocker device, a large number of pallet flow rack lines are arranged in contact with the side surfaces, and the side surfaces are work prohibited areas. Therefore, the pallet between the storage work area side and the picking work area side cannot be visually confirmed. Therefore, it is impossible to manage the date by visually checking the product.

The present invention solves the conventional problems described above, and uses a pallet flow rack line or the like to realize a first-in first-out product and an efficient picking function corresponding to various products. To aim.

Further, the present invention enables a wide range of picking such as a large amount of picking for each pallet, a medium amount of picking for each product case, and a small amount of picking for each piece, thereby realizing a highly flexible picking function. The purpose is to do.

A further object of the present invention is to facilitate date management of first-in first-out products by visual inspection.

In this device, warehousing (loading of pallets) is performed in pallet units from the warehousing port 13, and the pallets 12 that have been warehousing are sequentially moved by the transport device while shifting in pallet units in the direction of the arrow in the figure.

The picking work is performed in the picking work area 15 installed on the side of each line. In the picking work area 15, since the number of pallets = the picking width, the picking work is performed in a very wide range. It is possible to

The picking operation is performed based on the instruction of the picking list 24 printed by the printer 22 of the management system. When performing this picking operation, the worker determines which product to pick based on the picking list 24, and sequentially performs picking based on the pallet number (= commodity item).

In this case, the picking may be carried out in pallet units, but it is also possible to carry out picking of products on the pallet in piece units (units of individual pieces). When a plurality of cases (cases containing products) are mounted on one pallet 12, picking in each case is possible.

The products picked as described above are
It is placed on the dolly 16 and is transported to the outside and discharged. As described above, since the product picking work is performed in the wide picking work area 15 provided on the side surface side of each line, any pallet can be picked freely.

The transport mechanism section 28 is provided with a roller for mounting and moving the pallet 12, a drive mechanism (motor etc.) for rotating the roller, and the like. It is configured to be driven.

An optical sensor 29 including a light emitting portion 31 and a light receiving portion 32 for detecting the presence / absence of a pallet is provided in the transport mechanism portion 28. The optical sensor 29 is provided for each pallet location, and is attached so that the light beam 33 emitted from the light emitting unit 31 is directed toward the pallet 12 side.

Further, the light receiving section 32 is attached so that the reflected light from the pallet 12 can be received. Therefore, if the pallet 12 exists at a certain pallet location, the light beam 33 emitted from the light emitting unit 31 is reflected on the bottom surface side of the pallet, and the reflected light is incident on the light receiving unit 32. Therefore, the light receiving section 32 detects the reflected light.

Then, the detection signal detected by the light receiving section 32 is sent to the transportation control device 34, and the transportation control device 34 detects that the pallet 12 is present at the pallet location. When there is no pallet 12 in the pallet location, the light beam 33 emitted from the light emitting unit 31 is emitted.
Is diffused and does not enter the light receiving portion 32. Therefore, the transport control device 34 detects that there is no pallet at the pallet location.

In the case where the pallet 12 is automatically carried by the carrying device while performing a picking operation, the carrying device controls as follows. Normally, if the pallet 12 is present in the pallet location, the conveyance control device 34 detects the presence of the pallet 12 by the detection signal from the optical sensor 29. In this state, the transport control device 34 does not drive the transport mechanism unit 28.

Next, when the pallet is no longer in the pallet location, the transport controller 34 detects that the pallet 12 is no longer in the pallet location based on the detection signal from the optical sensor 29. At this time, the transport control unit 34 controls the transport mechanism 28 in the direction of the arrow in the figure to shift the pallet 12 to a pallet location without a pallet.

When the shifted pallet 12 reaches a predetermined position, the conveyance control device 34 detects that the pallet 12 has arrived at the pallet location based on a detection signal from the optical sensor 29. And immediately, the transport mechanism unit 2
8 is stopped.

As described above, when the pallet 12 is lost at the pallet location due to picking, the transport control device 34 detects the above-mentioned state and drives the transport mechanism unit 28 to shift the pallet 12 in the direction of the arrow shown in the figure. Meanwhile, all the pallets 12 are automatically packed to the end 14 side.

The pallets 12 to be stored are respectively loaded from the storage port 13 and sequentially moved in the direction of the arrow as shown above. However, when the pallet 12 reaches the end 14, it does not move any further. (Termination 14
Stop at).

That is, the pallet 12 loaded from the storage port 13 moves to the end 14 and stops, and picking work is performed on the way to the end 14.

§2: Explanation of device operation in Example 2 ...
See FIG. 8. FIG. 8 is an explanatory diagram of the apparatus according to the second embodiment. The first-in first-out stocker device is operated as follows. The line D of the pallet flow rack line 11 is not shown in FIG.

A large number of pallets 12 are mounted on each line of the pallet flow rack line 11. In this example, each pallet 12 is given a pallet number of # 1 to # 8. In this device, warehousing (loading of pallets) is performed in pallet units from the warehousing port 13, and the pallets 12 that have been warehousing are sequentially moved by the transport device while shifting in pallet units in the direction of the arrow in the figure.

The picking work is carried out in the picking work area 15 installed on the side of each line. In the picking work area 15, since the number of pallets = the picking frontage, the picking work is carried out in an extremely wide range. It is possible to

The picking operation is performed based on the instruction of the picking list 24 printed by the printer 22 (see FIG. 3) of the management system. When performing this picking operation, the worker determines which product to pick based on the picking list 24, and sequentially performs picking based on the pallet number (= product item).

In this case, the picking may be carried out in pallet units, but it is also possible to carry out picking of products on the pallet in piece units (individual units). When a plurality of cases (cases containing products) are mounted on one pallet 12, picking in each case is possible.

The products picked as described above are
It is placed on the conveyor line 37, transported to a predetermined position, and discharged. As described above, since the product picking work is performed in the wide picking work area 15 provided on the side surface side of each line, any pallet can be picked freely.

Further, since picked products are placed on the conveyor line 37 installed in the picking work area 15 and conveyed, the work efficiency is good and the picking work can be speeded up.

The picking operation will be specifically described.
As an initial state, the pallet 12 terminates at a certain line (for example, line A) of the pallet flow rack line 11.
From the 4 side, # 1, # 2, # 3, # 4, # 5, # 6, # 7,
It is assumed that they are arranged in the order of # 8. It is assumed that the pallets have products in stock.

In the above-mentioned state, the worker decides the product to be picked based on the picking list, and picks the designated product in the picking work area 15. Then, the picked product is placed on the conveyor line 37 and conveyed on the spot. For example, it is assumed that the picking target pallets are pallets # 4 and # 6.

When the picking is performed, the pallet 12
Remove the empty pallet from the line as the items above disappear and empty pallets will be generated. By this processing, the pallet is lost at the location where the pallet # 4 and the pallet # 6 were located.

As described above, when the pallet is used up, the pallet 12 is shifted by the pallet unit in the direction of the arrow in the figure in order to eliminate the location where the pallet is used up by the carrying device. Specifically, the pallet # 5, the pallet # 7, and the pallet # 8 are sequentially shifted in the direction of the arrow in the figure to pack the pallet toward the terminal end 14 side.

Then, a new pallet is loaded (loaded) in the opened location on the loading port 13 side. In this way, the picking work and the pallet storage (input) work are performed. By the above operation, low-rotation products are shifted to the right (end side) in pallet units.

The operation of the above apparatus has the following features. : Since the conveyor line 37 is installed in the picking work area 15, a large number of products can be picked efficiently.

Since the picking work of the products is performed in the wide picking work area 15 provided on the side surface side of each line, any pallet can be picked freely. That is, since the picking opening is large, any pallet can be easily picked.

[0134]: The state of merchandise can be easily monitored by the operator visually from the picking work area 15. Further, when an empty pallet is generated by picking and the empty pallet is removed from the line, the pallet on the pallet flow rack line is automatically shifted to the terminal end 14 side, so that the date management of the first-in first-out product can be automatically performed. .

[0135] In particular, in the field work, it is important for the workers to visually manage the products while the products are managed by the management system, but this visual management can be easily performed. : Products are managed as free locations by inventory management and input management, and it is possible to use pallet locations according to the sales of products.

First-in, first-out management of products can be easily performed, and the picked product is automatically shifted to the end side, so that the product replacement work is unnecessary. (Description of Third Embodiment) §1: Description of Device Configuration of Third Embodiment ... See FIG. 9 FIG. 9 is an explanatory diagram of the device of the third embodiment. The third embodiment is an example of an apparatus in which the apparatus of the second embodiment is combined with a digital picking system (hereinafter referred to as "DPS").
That is, in the second embodiment, when the picking work is performed, the worker looks at the picking list to determine the product to be picked, but in the third embodiment, the display terminal of the DPS is displayed without using the picking list. It is used to do picking work online in real time.

For this reason, the DPS is installed in the first-in first-out stocker device, and each line of the pallet flow rack line 11 has a D in pallet location unit.
A PS display terminal 40 is installed.

The display terminal 40 has a workstation 21 (described later) of the management system for each line.
The work station 21 sends information to the respective display terminals 40 to display the information and gives a picking instruction.

The display terminal 40 is installed in each pallet location unit, for example,
It is hung from the ceiling.

The display terminal 40 is provided with a display section for giving a picking instruction, a picking completion confirmation button and the like. The display section displays the picking instruction information (the name of the product to be picked, the quantity, and other information) sent from the workstation 21, and the picking completion confirmation button is used by the worker when the picking work is completed. This is for pushing to send information on picking completion to the workstation 21.

Picking using the DPS is performed as follows. When performing the picking work, first, the picking instruction information is sent from the workstation 21 to the display terminal 40 and displayed on the display unit of the display terminal 40. A picking instruction is given to the worker based on this display information.

The worker specifies the pallet 12 to be picked based on the displayed picking instruction information,
Products are picked from the pallet 12. When the pallet 12 runs out of products by this picking operation, the pallet 12 is removed from the pallet flow rack line 11. After that, the worker inputs the information that the picking work is completed by pressing the picking completion confirmation button of the display terminal 40, and sends it to the workstation 21.

In this case, each pallet 12 has a pallet I
Since the D label 41 is attached, information on which pallet has been removed can be sent to the workstation 21 by reading the information on the pallet ID label 41 and inputting the information from the input device 23 of the management system. The information on the pallet is managed by the workstation 21.

During the above-mentioned picking operation, when there is no product on the pallet 12 due to the picking and the pallet is removed from the line, the pallet is lost at the pallet location.

In such a case, an optical sensor is installed in each pallet location unit in the pallet flow rack line 11 (see FIG. 6), and the transfer control device determines the pallet location based on the detection signal of the optical sensor. Detects that there is no palette. Then, under the control of the transfer control device, the transfer mechanism portion of the pallet flow rack line 11 is driven to automatically shift the pallets sequentially toward the terminal end side.

For example, when all the products in pallet # 3 are picked by the above-mentioned picking operation, pallet #
3 is removed from the pallet flow rack line 11. At this time, the pallet # 4 and pallet # 5 are shifted in the direction of the arrow in the drawing by the drive of the transport mechanism section, and all the pallets are automatically packed to the end side.
