Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an article storage device, and more particularly to an article storage device for placing and storing articles such as vials on a shelf.

``Prior Art'' Conventionally, as an article storage device for placing and storing articles on shelves in a storage warehouse, articles that have been conveyed in a line by a conveyor are directly sequentially supplied onto the shelves. Another known method is to grasp and suspend articles from a conveyor in a single row in an amount equivalent to the width of the shelf, and then carry the suspended articles one row at a time from the back of the shelf. ing.

"Problem to be Solved by the Invention" However, although the former method allows goods to be quickly supplied into the storage, especially when the storage is a freeze-drying storage or a freezer, the shelves may freeze. Since the items cannot be slid smoothly on the shelves, it has been difficult to store them smoothly. This also applies to cases where the shelf has a structure that makes it difficult for articles such as nets to slide smoothly.

On the other hand, with the latter method, items can be reliably stored even on shelves where it is difficult to slide items, but the gripping mechanism that grips and suspends items in a single row is It takes time to reciprocate in and out of the storage for each row, and if the storage is a freeze dryer, freezer, or hot storage, storage will continue until the shelves are filled with items. Because it is necessary to leave the door of the warehouse open,
Thermal energy loss was increasing.

"Means for Solving the Problems" In view of such circumstances, the present invention provides a storage for accommodating shelves on which articles are placed, a conveyor for transporting and supplying articles, and a combination of the shelves and the conveyor. A support frame disposed in between, a first sprocket provided on the shelf side of this support frame, a second sprocket provided on the conveyor side, an endless chain spanning both of these sprockets, and a top of this endless chain. a mounting plate disposed on the conveyor side and swingably connecting the end portion on the conveyor side to the endless chain; and a support member attached to the endless chain to support a lower part of the shelf side of the mounting plate. a drive mechanism for advancing the placing plate through the endless chain and carrying a predetermined amount of articles supplied onto the placing plate from the transport conveyor onto the shelf; a regulating member that comes into contact with the article and restricts the article from being retreated to the conveyor side together with the placing plate; The object of the present invention is to provide an article storage device that rotates around a first sprocket and moves downward, thereby lowering the tip of the placement plate to come into sliding contact with the surface of the shelf.

"Function" According to such a configuration, the articles from the transport conveyor are stored on the placing plate until a predetermined amount is reached, and then the placing plate is advanced to move the articles thereon onto the shelf. Then, the regulating member is brought into contact with the article carried on the shelf to prevent the article from being retreated to the conveyor side together with the placing plate, and in this state, the placing plate is pulled out. It is now possible to place and store a large number of items on a shelf at once, and therefore in a short period of time, even when it is difficult to slide items smoothly on the shelf.
Items can be stored reliably.

In addition, in the present invention, the support member attached to the endless chain is rotated and moved around the first sprocket when the tip of the placement plate is advanced to above the shelf, and thereby the support member is placed on the shelf. Since the tip of the plate is lowered so that it comes into sliding contact with the surface of the shelf, when the tip of the mounting plate is moved above the shelf, a relatively large gap can be maintained between the two. Even if the loading plate bends downward due to the weight of the article or vibrates up and down while traveling, the loading plate can be prevented from colliding with the shelf.

"Example" The present invention will be described below with reference to the illustrated example.
In FIG. 1, a storage warehouse 1 for storing and freeze-drying articles is equipped with a plurality of shelves 2 inside.
Each shelf 2 is raised and lowered one stage at a time by a lifting mechanism (not shown) provided in the storage 1. On each shelf 2, articles can be supplied onto or discharged from the shelf 2 through an opening 3 corresponding to one shelf level formed on the front surface of the storage 1.

The above-mentioned opening 3 can be opened and closed by a shutter (not shown), and the front side of the storage compartment 1 provided with this opening 3 is a door, and by opening the door as necessary, the storage compartment can be opened and closed. The entire front of 1 can be opened.

As shown in FIG. 2, in this embodiment, three of the above-mentioned storage compartments 1 are arranged side by side at a predetermined interval, and on the opening 3 side of each storage compartment 1, the storage compartments 1 are arranged side by side. One conveyor 4 that conveys articles in parallel with
has been set up. One transfer device 5 is provided between each storage 1 and the transport conveyor 4 for supplying the articles transported by the transport conveyor 4 to each storage 1, and this transfer device 5 is connected to the transport conveyor 4. By making the transfer device 5 movable along a rail 6 laid parallel to the conveyor 4, the transfer device 5 can be stopped at a position in front of any one of the storage containers 1, and the articles from the transport conveyor 4 can be transferred into the storage storage 1. can be supplied to or discharged from the

On the upstream side of the conveyor 4, there is provided a grouping device 10 that groups the articles conveyed by the conveyor 4 in a vertical line and in contact with each other into a predetermined number and sends them downstream. . As shown in FIG. 3, the grouping device 10 is normally rotated freely by the articles 11 as they pass, and is braked by a brake (not shown) when necessary.
The stopper wheel 12 prevents the articles 11 from passing through the stopper wheel 12, and the timing screw 13 forms a required gap between the articles 11 that have passed through the stopper wheel 12 while in contact with each other.

Further, the grouping device 10 is equipped with a pair of sprockets 14 arranged at a predetermined interval on one side of the downstream side of the timing screw 13, and an endless chain 15 is stretched between the two sprockets 14. One sprocket 14 is linked to a drive motor (not shown), and the drive motor allows the endless chain 15 to circulate in the same direction as the transport conveyor 4 and at a speed slightly slower than the transport speed of the transport conveyor 4. That's what I do. A stopper 16 is attached at a predetermined position of the endless chain 15 to come into contact with the article 11 conveyed by the conveyor 4 and apply a brake to the article 11.

Therefore, according to the grouping device 10, the articles 11 that have passed through the stopper wheel 12 in contact with each other are formed with a required gap between the articles by the timing screw 13, and The traveling operation of the endless chain 15 is synchronized. And endless chain 15
The stoppers 16 attached to each stopper 16 are inserted into the gaps between each predetermined number of articles 11 to apply braking to the articles.
The images are grouped into a predetermined number corresponding to the interval between the images.

By the way, the article conveyance speed of the conveyor 4 is generally set at a speed that allows it to supply slightly more articles 11 than the throughput of the articles 11 by the timing screw 13. Since the articles 11 on the upstream side contact each other and exert a pressing force on each other, it is necessary to provide guide rails 17 on both sides of the conveyor 4 to guide the articles 11 and prevent them from falling off.

On the other hand, the above-mentioned grouping device 10 groups them into a predetermined number of groups and transfers them to the conveyor 4.
Since the articles 11 conveyed by the conveyor 4 do not substantially exert any pressing force on each other, there is essentially no need to provide guide rails 17 for guiding the articles 11 on both sides of the conveyor 4. In the embodiment, for safety, guide rails 1 are provided on both sides of the conveyor 4, except for the front part of each storage 1, which will be described later.
7 is provided.

However, as shown in FIG. 1, in this embodiment, the transfer device 5 includes four carry-in mechanisms 5A, 5B, 5C, and 5D that each place an article 11 and reciprocate in a direction orthogonal to the conveyor 4. It is equipped with Each of the carrying mechanisms 5A to 5D is equipped with a rectangular thin plate 20 made of stainless steel or synthetic resin, and each plate 20 is placed with both longitudinal sides bent upward. The article 11 is prevented from falling off in the width direction.

Each of the mounting plates 20 is arranged parallel and horizontally so that its upper surface is substantially at the same height as the conveyor 4, and
When the mounting plate 20 is positioned at the rearward end, the rear end is in a position where it is almost in contact with the conveyor 4 without creating a large gap (see FIG. 4).

In addition, as shown in FIGS. 1 and 2, the transport conveyor 4 is located at a position opposite to the transfer device 5 side of the transport conveyor 4 and at a position facing each storage storage 1. Three extrusion mechanisms 21 are provided to extrude the articles 11 that have been conveyed along the conveyor belt toward the transfer device 5 side.

Each extrusion mechanism 21 is equipped with an extrusion lever 22 that comes into contact with one group of articles 11 conveyed on the conveyor 4 and transfers the articles onto the mounting plates 20 of each carry-in mechanism 5A to 5D. The same number of push-out levers 22 as the carry-in mechanisms 5A to 5D are provided for each push-out mechanism 21.

Each of the pushing levers 22 is individually linked to a drive source (not shown), and when activated, is reciprocated in a direction perpendicular to the conveyor 4 to press and supply the one group of articles 11 onto the mounting plate 20. At the same time, when it is not in operation, it is moved to the raised position so that it does not come into contact with the articles 11 conveyed by the conveyor 44 (see FIG. 6).

In this way, the article 11 conveyed on the conveyor 4 is pushed out by the pushing lever 22 in the direction perpendicular to the conveyor 4 and moved onto the placing plate 20, so that Therefore, as mentioned above, the guide rail 17 cannot naturally be provided at the front position of each storage 1.

If the grouping device 10 is not provided on the upstream side of the conveyor 4, the articles 11 conveyed by the conveyor 4 exert a pressing force on each other as described above.
Therefore, when storing articles in the storage warehouse 1 on the downstream side, the articles 11 will fall off from the front part of the storage warehouse 1 on the upstream side. The guide rail 17 must be attached or detached depending on whether or not the transfer device 5 is provided.

On the other hand, in this embodiment, the conveyor 4
Since the grouping device 10 is provided on the upstream side of the container so that no pressing force is exerted between the grouped articles 11, the guide rail 17 is not provided at the front of the storage container 1 as described above. The article 11 will not fall off even when the guide rail 17 is attached and removed, and the article 11 will not fall off the conveyor 4 due to forgetting to attach the guide rail 17. Nor.

Next, a first drive mechanism 25 is provided below each of the mounting plates 20 to move each of the mounting plates 20 forward and backward separately in the longitudinal direction.
The drive mechanism 25, as shown in FIGS. 4 and 5,
A plurality of rotating shafts 27 are rotatably supported at predetermined positions of a support frame 26 disposed between the storage warehouse 1 and the conveyor 4, and a pair of sprockets are attached to each side of each rotating shaft 27. 28 and
A pair of endless chains 29 stretched in parallel between each sprocket 28 and the support frame 26
The guide member 30 is attached to the guide member 30 and guides the upper straight portion of each endless chain 29 in a straight line.

Each of the mounting plates 20 is disposed on each pair of endless chains 29, and the bottom surface of the distal end of the mounting plate 20 on the conveyor 4 side is connected to the endless chain 29 via a connecting member 31. In addition to being swingably connected, the bottom surface of the distal end of the mounting plate 20 on the storage 1 side is supported by being placed on a rod-shaped support member 32 attached to a predetermined position of the endless chain 29. There is. Further, the rotary shaft 27 is interlocked with a servo motor 35 via a sprocket 33 attached thereto and a chain 34 stretched around the sprocket 33. Therefore, by rotating the servo motor 35 in the forward and reverse directions, the mounting plate 20 can be moved back and forth via the endless chain 29.

By the way, as described above, the upper surface of the mounting plate 20 is substantially at the same height as the transport conveyor 4, and the rear end of the mounting plate 20 is close to the transport conveyor 4 at the retreating end position. However, at the rearward end position of the mounting plate 20, the sixth
As shown in the figure, a distance l is formed between the tip of the mounting plate 20 and the shelf 2 of the storage 1, which is at least the thickness of the door (not shown) of the storage 1, and the above-mentioned mounting plate 20 onto the shelf, the placement plate 20 is placed at a position that is higher than the surface height of the shelf 2 in the storage 1 by a required amount δ.

Therefore, when the placing plate 20 is advanced toward the shelf 2 side by the first drive mechanism 2, the placing plate 20 may bend downward due to the weight of the article 11, or move up and down while moving forward. Even if it vibrates, the tip of the mounting plate 20 can reliably enter above the shelf 2 without colliding with the shelf 2.

When the tip of the mounting plate 20 reaches above the shelf 2, the support member 32 attached to the endless chain 29 rotates around the sprocket 28 on the storage compartment 1 side and moves downward. The mounting plate 20 has been moved in a horizontal state due to the
The tip is lowered and placed on the surface of the shelf 2, so that it can be slid on the surface of the shelf.

Further, as shown in FIG. 1, above the four placing plates 20 described above, there is a conveying means for moving the articles 11 supplied onto each placing plate 20 on the placing plates 20. There are 40. This conveyance means 40
is equipped with a pair of T-shaped movable columns 41 arranged on both sides of four mounting plates 20, and the lower end of each movable column 41 is arranged as shown in FIGS. 1 and 7. , the above-mentioned mounting plate 20 is placed on both sides of the support frame 26.
A screw shaft 42 disposed and supported in parallel with the moving direction of
It is screwed together. Each screw shaft 42 is linked to a servo motor (not shown), and when the screw shaft 42 is rotated by the servo motor, each movable support 41 can be reciprocated in the direction of movement of the mounting plate 20. ing.

A box body 43 is provided at the upper end of each of the movable columns 41, and a pair of rotating shafts 44 are installed at both ends of each box body 43 in a direction perpendicular to the moving direction of the mounting plate 20. Furthermore, a plate-shaped swing bar 4 is provided on each rotating shaft 44 in parallel thereto.
5,46 is installed. These swing bars 45 and 46 are adapted to swing independently, respectively, by two cylinder devices 47 provided within the box body 43 shown in FIG.

The swing bars 45 and 46 operated by each cylinder device 47 are located in the upper position shown by the solid line in FIG. 7 in the non-operating state, but when each cylinder device 47 is operated, Each swing bar 4
5 and 46 are lowered to the lower position shown by the imaginary line, so that they can come into contact with the article 11 on the placement plate 20.

Further, the transfer device 5 includes a movable regulating member 50 for moving and placing the articles 11 on each placing plate 20 on the shelf 2 described above, and this movable regulating member 50 is connected to a second drive mechanism 51. Therefore, it is moved forward and backward in the direction of movement of the mounting plate 20, and is also raised and lowered.

The movable regulating member 50 is disposed in a direction perpendicular to the moving direction of the placing plate 20, and the placing plate 20 extends to both sides of the four placing plates 20 at both ends thereof.
An arm 52 extending in the direction of movement of the arm 52 is connected, and its base on the conveyor 4 side is screwed to a screw shaft 53 which is disposed parallel to the screw shaft 42 on the side surface of the support frame 26 and rotatably supported. I'm making it match. The screw shaft 53 is connected to the second drive mechanism 5.
1, and when the screw shaft 53 is rotated by the servo motor, the movable regulating member 50 can be reciprocated in the direction of movement of the mounting plate 20. I have to.

In addition, each arm 52 has, as shown in FIG.
A linear engagement protrusion 54 is formed along the longitudinal direction on the outside of the pair of arms 52, and each engagement protrusion 5
4 are slidably engaged with the engagement grooves 56 of the rotating member 55. Each of the rotating members 55 is formed of a cylindrical body, and is supported by an elevating member 57 so as to be able to rotate around its axis. They are respectively attached to pillars 58 erected on both sides of the storage 1 side of the frame 26 so as to be movable up and down. Each of the elevating members 57 is synchronously moved up and down by the same amount by an unillustrated elevating mechanism constituting the second drive mechanism 51.

Therefore, when the movable regulating member 50 is moved forward or backward, the engagement convex portions 54 of the arms 52 at both ends are guided by the engagement grooves 56,
By adjusting the height position of 6, the height position of the movable regulating member 50 can be adjusted via the arm 52.

Furthermore, each of the shelves 2 has a first
As shown in the figure, a fixing regulating member 60 that is lower in height than the articles 11 is installed on the back side, and this fixing regulating member 60 prevents the articles 11 from coming into contact with the inner wall of the storage 1. The wall surface and article 1
1 to form a gap in which the movable regulating member 50 is inserted.

In the above configuration, first, the operation of storing articles 11 in each storage 1 will be explained. The transfer device 5 is initially positioned in the front position of the storage 1 on the most upstream side. 4 in the extrusion mechanism 21 placed in front of the storage 1
The three push levers 22 are operated sequentially from the most downstream side to the upstream side of the conveyor 4.

In the state before the transfer device 5 starts operating, as shown in FIG. 9a, the mounting plate 20 and movable regulating member 50 of each carrying mechanism 5A to 5D are located at the backward movement end, and the movable regulating member 50 is article 11
It is located at the rising end where there is no contact with the Further, the pair of swing bars 45 and 46 are also connected to the conveyor 4.
It is located at the reverse end of the approach, and each swing bar 4
5 and 46 are each located at the rising end and are in a horizontal state where they do not come into contact with the article 11. Furthermore, regarding the storage 1, the top shelf 2 is the mounting plate 2.
It is located at a position lower than 0 by the predetermined amount δ.

In this state, when a row of articles 11 grouped into a predetermined number by the grouping device 10 described above is conveyed by the conveyor 4, the push lever 22 corresponding to the most downstream carry-in mechanism 5A is activated. The articles 11 are sequentially moved and placed on the placing plate 20 one row at a time (FIG. 9a). At this time, the extrusion levers other than the extrusion lever in operation are retracted to an upper position where they do not come into contact with the article 11.

When a predetermined amount of articles 11, for example, 1/3 of the amount to be placed on the shelf 2, is stored on the placement plate 20 of the carry-in mechanism 5A by the repeated operation of the push lever 22, the previous operation is activated. Extrusion lever 2
2 retreats upwards, and from the push lever 22 1
The push-out lever 22 corresponding to the carry-in mechanism 5B on the upstream side starts operating, and the above-described predetermined amount of articles 11 is stored on the mounting plate 20 of the carry-in mechanism 5B. Therefore, the most downstream loading mechanism 5A
Even if a predetermined amount of articles 11 are filled on the mounting plate 20 of the conveyor 4, the conveyor 4 will not be stopped and the conveyance of the articles 11 will not be stopped.

On the other hand, when the above-mentioned predetermined amount of articles 11 are stored on the placement plate 20 of the carry-in mechanism 5A, the placement plate 2
0 starts to move forward, and when the rear end side of the article 11 of a predetermined amount of the group of articles passes over the rear swing bar 46, the advance is temporarily stopped (FIG. 9b).

In this state, the rocking bar 46 on the rear side is rocked downward and then moved forward by a predetermined amount, so that the rocking bar 46 comes into contact with the article 11 and moves the entire article onto the mounting plate 20. After that, the swing bar 46 moves upward and returns to the original rearward end position (FIG. 9c). At this time, the mounting plate 2
0 is advanced by a predetermined amount, the swing bar 46 is lowered, so that the mounting plate 20 of the carry-in mechanism 5B
The swing bar 46 does not come into contact with the article 11 fed above.

The article 11 is moved to the mounting plate 2 by the swing bar 46.
0, the loading plate 20 starts to move forward again, and when its tip reaches above the uppermost shelf 2 on the storage 1 side, as described above, the loading plate 20 is moved forward to the endless chain 29. The mounted support member 32 rotates around the sprocket 28 and moves downward, so that the mounting plate 20 then slides on the surface of the shelf 2 (FIG. 6).

When the rear end side of the group of articles on the placing plate 20 passes the movable regulating member 50, the movable regulating member 50 is lowered to a position where it can come into contact with the article 11, and at the same time the moving speed of the placing plate 20 (Figure 9d) When the tip of the placing plate 20 approaches the fixed regulating member 60 provided at 2, the placing plate 20 is stopped, but the movable regulating member 50 continues to move forward and brings the article 11 into contact with the fixed regulating member 60. position, that is, to the back of shelf 2, and stop there (Fig. 9e,
f figure).

In this state, the placing plate 20 starts to retreat while the movable regulating member 50 is stopped, so that the placing plate 20 is pulled out from the bottom of the article 11 whose retreat is regulated by the movable regulating member 50. , the articles 11 are moved from the placing plate 20 to the shelf 2, and thereby the articles 1, which are 1/3 of the number of articles to be placed on the shelf 2, are moved from the placing plate 20 to the shelf 2.
1 will be placed and accommodated (Fig. 9g). When the placing plate 20 is completely pulled out from between the article 11 and the shelf 2, the movable regulating member 50 is also retreated integrally with the placing plate 20, and eventually the movable regulating member 50
0 and the mounting plate 20 are returned to their original positions (FIGS. 9h and 9i).

The above operations are sequentially transferred from the most downstream loading mechanism 5A to the upstream loading mechanisms 5B, 5C, and 5D, and a predetermined amount of articles 11 are placed on the mounting plate 20 of the most upstream loading mechanism 5D. When the above-mentioned operations are started after the items are stored, the grouped articles 11 from the transport conveyor 4 are once again supplied onto the placement plate 20 of the most downstream carry-in mechanism 5A. Therefore, each of the carry-in mechanisms 5A to 5D carries in the articles to be stored on the shelf 2 in 3 parts of 1/3 each, and as a result, the four carry-in mechanisms 5A to
5D is activated a total of 12 times to fill all of the shelves on one level with articles 11.

Then, the most upstream loading mechanism 5D is the last 12
When the article 11 is carried into the shelf 2 by the second operation, the shelf 2 is raised by one level by a lifting mechanism (not shown) provided in the storage 1, and a new empty shelf is placed from each placing plate 20. is also located at a lower position by the predetermined distance δ. During this time, the conveyor 4 continues to supply the article 11 to the most downstream carry-in mechanism 5A, and the conveyor 4 does not stop conveying the article 11.

As described above, the articles 11 are sequentially placed and stored on the shelves 2 of each stage, and when all the shelves 2 are filled with articles, the operation of the conveyor 4 is stopped, and the transfer device 5
is moved to the front position of storage 1 on the downstream side,
After that, the above-mentioned operation is repeated until all storage warehouses 1
Articles 11 are carried into the interior.

Next, when carrying out the articles 11 from the storage warehouse 1, the articles 11 are carried out in order from the lowermost shelf 2 to the upper shelf 2 of the storage warehouse 1, and the four carrying mechanisms 5A to 5D performs the same operation all at once,
Moreover, all the articles 11 on the shelf can be carried out in one operation.

Before the transfer device 1 starts carrying out the articles 11, as shown in FIG.
are respectively located at the reverse end, and the swing bars 45, 46 are located at the forward end position near the storage compartment and at the raised position.

From this state, the placing plate 20 and the movable regulating member 50 start moving forward, and the movable regulating member 50 advances between the top surface of the article 11 and the bottom surface of the upper shelf 2 and is moved to the back side of the shelf 2. , and the other mounting plate 20
As the tip moves forward, it is inserted between the bottom of the article 11 whose movement is restricted by the fixed regulating member 60 fixed at the back of the shelf 2 and the surface of the shelf 2 (Fig. 10b).

When the movable regulating member 50 approaches the wall of the storage 1, that is, when it advances to above the fixed regulation member 60, its advancement is stopped, and it further descends from that position to meet the wall of the storage 1 and the innermost article. 11. On the other hand, the above-mentioned placement plate 20
advances to a position where its tip abuts the fixed regulating member 60, and moves all the articles on the shelf 2 onto each placing plate 20.
When it is moved and placed on top, its advancement is stopped (Figures 10c and 10d).

In this state, first, the movable regulating member 50 starts to retreat and moves the article 11 by a predetermined amount in the backward direction on the mounting plate 20 (Fig. 10e). Since the member 50 starts retreating at the same speed, the articles 11 on the placement plate 20 are carried out from inside the storage 1, and the movable restriction member 50 and the placement plate 20 are moved to their respective positions before the start of operation. (10f, 10g)
figure).

In this way, by moving the article 11 by a predetermined amount in the backward direction on the placement plate 20, that is, toward the center of the placement plate 20, it is possible to reliably prevent the article 11 from falling off the placement plate 20. In addition, when the tip, that is, the left end of the placing plate 20 is separated from the shelf 2 to the right, the left end is bent by the weight of the article 11 and the article 11 is removed from the placing plate 20. It can prevent it from falling off.

Then, when the placing plate 20 is returned to the backward position, the article 1 on the left side of the group of articles on the placing plate 20 is
1 passes over the left swinging bar 45 located above toward the conveyor 4 side, and when the swinging bar 45 is moved downward from this state to a state where it can come into contact with the article 11, the conveyor The mounting plate 20 is retracted toward 4, and its swing bar 45 is stopped.
Then, the article 11 is moved to the end of the mounting plate 20 (FIG. 10h).

Thereafter, when the swing bars 45 and 46 are moved to the forward end, the other swing bar 46 is moved downward (FIG. 10j), and when the swing bar 46 is retreated again, the swing bar 46 is moved downward (FIG. 10j). presses the article 11 and pushes it onto the conveyor 4. At this time, the swing bar 46 is configured to intermittently push out the articles 11 on the mounting plate 20 one row at a time onto the conveyor 4, so that the articles 11 are pushed out in one row by the conveyor 4. (10th k)
figure).

When all the articles 11 are carried out from the lowermost shelf 2 of the storage warehouse 1 in the above manner, the shelf 2 is lowered by one level by a lifting mechanism (not shown), and the above-mentioned operation is repeated again to accommodate the items. All the articles 11 are carried out from the warehouse 1.

"Effects of the Invention" As described above, according to the present invention, even if it is difficult to slide the articles smoothly on the shelf, the articles can be stored reliably and in a short time, and Even if the mounting plate bends downward due to the weight of the item or vibrates up and down while moving,
This provides the effect of reliably preventing the mounting plate from colliding with the shelf.
