TECHNICAL FIELD The present invention relates to an article storage device, and more specifically, an article storage device that sequentially stores and stores articles such as vials on a plurality of shelves in a storage cabinet. Regarding

"Prior Art" Conventionally, as an article storage device that sequentially stores and stores articles on each of a plurality of shelves, an elevating mechanism that sequentially positions each shelf in a storage cabinet at a first delivery position of a predetermined height, A mounting plate that is moved by the first drive mechanism to the shelf located at the first delivery position and an external second delivery position, and a pressing member that comes into contact with the rear end row in the transport direction of the group of assembled articles. An article storage device including: a second drive mechanism that moves and pushes up and down the pressing member; and an article transport mechanism that loads and unloads a group of articles on a mounting plate located at the second delivery position. It is known (JP-A-62-180802).

When carrying articles on the shelves in the storage with this article storage device, the elevating mechanism positions the required shelves in the storage at the first delivery position, and the article transfer mechanism performs the second delivery. An article group is carried in on the mounting plate located in the position. Then, the mounting plate described above is moved to the second position by the first drive mechanism.
After moving from the position to the shelf located at the first delivery position, the placing plate is retracted while the pressing member is in contact with the rear end row of the article group in the conveying direction, and the article group is moved by this pressing member. The placement plate is pulled out from the lower side of the article group while preventing the article group from being retracted integrally with the placement plate, and the article group is placed on the shelf.

Then, when the placing plate pulled out from the lower side of the article group is returned to the original second position, the elevating mechanism moves the next shelf to the first delivery position, and the article transport mechanism moves it to the second delivery position. By carrying in the article group on the placed mounting plate and repeating the above-mentioned operation, the article group can be carried in order on each shelf in the storage.

On the other hand, when carrying out an article from each shelf in the storage, first, the required shelves in the storage are positioned at the first delivery position by the elevating mechanism, and then the mounting plate is advanced. The loading plate is inserted between the shelf and the article group on the shelf. Then, when the article group is placed on the placing plate, the pressing member is advanced to pass through the article group and then is lowered to abut on the rear end row in the carrying-out direction of the article group.

In this state, the placing plate and the pressing member are integrally retracted to prevent the articles in the rear end row from falling off the placing plate by the pressing member, and the article group on the shelf is moved to the second delivery position. Then, the article group may be carried out from the placing plate positioned at the second delivery position by the article transport mechanism.

[Problems to be Solved by the Invention] However, in the article accommodating apparatus having the above configuration, the placing plate is pulled out from the article group carried on the shelf, and the placing plate is placed below the article group placed on the shelf. Since it is necessary to push in, there is a risk that the article will become unstable and fall when pulling out or pushing in, and especially when pushing the placing plate, some articles are pushed onto the article group and There is a risk that the articles are placed on the article group and then fall out from the article group when the placing plate is pulled out.

In view of such a situation, the present invention provides an article storage device in which there is no risk of the articles falling or falling when the articles are carried in or out of a shelf.

"Means for Solving the Problem" That is, the present invention relates to a storage case having a plurality of shelves inside, a lifting mechanism for sequentially positioning each shelf at a first delivery position of a predetermined height, and an outside of the storage case. Second adjacent to
A delivery position, a third delivery position provided adjacent to the second delivery position, and a tray having a side wall provided on one side thereof and one side surface thereof opened so as to be detachable, and the tray is provided with the first delivery position. A tray transport mechanism for transporting between a second delivery position and a shelf in the storage cabinet located at the position, and a frame member surrounding the group of collected articles integrally with the article group, 2 A tray located at the delivery position and a frame transfer mechanism for moving the tray to the third delivery position via the open portion of the tray and raising and lowering the frame member, and carrying the article group into the third delivery position, or An article transport mechanism for carrying out the article is provided.

[Operation] According to the above configuration, when the articles are loaded onto the shelves in the storage, the article transport mechanism transports the article group to the third delivery position, and then the frame transport mechanism moves the frame members to the third frame. The article group at the delivery position is moved upward and lowered, and the frame member surrounds the article group. Then, when the tray is moved to the second transfer position by the tray transport mechanism, the frame member is moved integrally with the article group, and the article group is carried into the tray through the open portion of the tray. On this occasion,
Since the periphery of the article group is surrounded by the frame member, the article group can be smoothly carried onto the tray without being overturned.

When the article group is carried in and placed on the tray, the frame transport mechanism releases the holding of the frame member and leaves the frame member on the tray while surrounding the periphery of the article group with the frame member. Alternatively, if necessary, the frame transport mechanism integrally includes a frame member, and the frame member is pulled up to release the surroundings of the group of articles. In any case, when the article group is loaded onto the tray, the tray transport mechanism loads the tray from the second delivery position onto the shelf in the storage located at the first delivery position. At this time, Since the group of articles is loaded onto the shelf together with the tray, the articles can be smoothly loaded onto the shelf while preventing the articles from falling over. In particular, when the tray is carried in together with the frame member, the articles can be more completely prevented from falling.

Next, when the tray transport mechanism leaves the tray on the shelf in the storage cabinet and retracts from the storage cabinet to the outside, the elevating mechanism positions the next shelf at the first delivery position, and this state is brought about. The tray transport mechanism again enters into the storage box, engages with the tray, and pulls it out from the first delivery position to the second delivery position. When the tray is pulled out to the second delivery position, when the frame member is left on the tray, the frame member is placed on the tray in advance, so the frame transport mechanism is placed on the tray. The frame member is engaged with and raised. This frame transport mechanism moves the frame member above the group of articles newly carried into the third delivery position by the article transport mechanism regardless of whether the frame member is left on the tray or not. The frame member is caused to descend, and the frame member surrounds the periphery of the article group. After that, the above-mentioned operation is carried, and the article group is carried in on each shelf together with the tray.

In response to the above-described article loading operation, when the article is unloaded from the shelf in the storage, the tray transfer mechanism moves the tray located at the first delivery position on the shelf in the storage from the shelf. It comes to be drawn out to the second delivery position outside. At this time, the article group together with the tray can be smoothly carried out from the shelf.

When the tray is pulled out to the second delivery position, the frame transfer mechanism is engaged with the frame member pulled out from the shelf integrally with the tray, or the frame member integrally provided with the frame transfer mechanism is lowered to lower the article. Enclose the group. Then, when the frame member is moved from the second delivery position to the third delivery position by the frame transport mechanism, the article group is tumbled to the third delivery position through the open portion of the tray while being surrounded by the frame member. You will be able to move smoothly.

Further, when the frame member is lifted up at the third delivery position and the surrounding of the article group is released, the article group is carried out from the third delivery position to the outside by the article transport mechanism, while the tray at the second delivery position is It is returned to the original shelf by the tray transfer mechanism. At this time, when the frame member is not provided integrally with the frame transfer mechanism, the frame member is placed on the tray at the second transfer position again from the third transfer position by the frame transfer mechanism. The frame member and the tray are returned to the original shelves.

On the other hand, the frame member 8 lifted at the third delivery position C is returned to the tray 7 at the second delivery position by the endless chain 39 continuing to move in the counterclockwise direction, and the frame member 8 is placed on the tray 7. Then, the endless chain 39 is slightly run in the opposite clockwise direction, and the engagement between the hook 42 'of the fixed arm 43' and the engaging portion 8a of the frame member 8 is released. Thereafter, when the empty tray 7 is returned to the uppermost shelf 2 by the transporting means 19 of the tray transporting mechanism 9 and the cylinder device 25, the raising / lowering mechanism 5 raises the storage case 1 to move it to the next lower shelf 2. Is located at the first delivery position A, and the same work is repeated thereafter.

In addition, when the storage is provided in a fixed position such as a large freeze-drying short store, the frame member 8 does not have to be left on the tray 7 as in the case of transporting the storage 1. In that case, the frame member 8 may be fixed to the movable block 37 because there is little risk of the article falling.

Further, although the article accommodating apparatus of the above-described embodiment is configured so that the article group can be loaded into and unloaded from the storage box 1, it can be configured as a dedicated loading / unloading machine.

[Effect of the Invention] As described above, according to the present invention, since the article group is carried in or carried out on the tray in a state in which the periphery of the article group is surrounded by the frame member, the container falls at that time. In addition, since the article group together with the tray is carried in or out on the shelves in the storage box, the articles can be prevented from tipping over at that time, and therefore the article group in the storage box can be prevented. The effect that the carrying-in or carrying-out work can be carried out smoothly and surely can be obtained.
