Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shelving device for an automatic warehouse.

[0002]

2. Description of the Related Art An automatic warehouse is a stacker crane type in which a movable carriage is provided with a lift that can be raised and lowered, a type in which the movable carriage only travels horizontally on rails, or a lift in which the movable carriage is only moved up and down. There are types that are configured in a shape. Among these, as a shelf device in an automated warehouse of a type in which a moving carriage only travels horizontally on a rail, Japanese Utility Model Publication No. 6-22642 discloses a rack device parallel to the rail on the opposite side of the traveling path of the moving carriage. A rear support frame extending in the direction is arranged, and strip-shaped shelf plates extending in the depth direction in a plan view are arranged at appropriate intervals between the rail and the rear support frame, and each shelf plate is connected to the rail and the rear by bolts or the like. There is disclosed a configuration in which a side edge of a rectangular container (box or tray) for storing luggage is supported by shelf plates that are fixed to a support frame and are adjacent to each other.

That is, in this conventional shelving device, a space is provided between adjacent shelves.

[0004]

In the case of a type in which luggage is stored in a container, such as the automatic warehouse of the above publication, since the container has sufficient strength, a space is provided between adjacent shelf boards. You may form. However, the means for storing and storing the luggage in the container has the drawbacks that the utilization efficiency of the space is low and it takes time to take the luggage in and out of the container. For this reason, recent automated warehouses are required to have a function of allowing loads of different sizes to be directly placed on shelves without using containers.

When the luggage is directly placed on the shelf in this way, the entire bottom surface of the shelf is covered with the shelf board so that the entire bottom surface of the luggage is supported by the shelf board. In that case, since a large number of shelves are used in one automated warehouse, the means for fixing the shelves with bolts or the like as described in the above publication requires a great deal of time and effort to attach the shelves. Therefore, there is a problem that the workability of assembling and disassembling is poor. Further, since a member for supporting the shelf plate, such as a rail or a rear support frame, needs to be provided with a hole for inserting a bolt, there is a concern that the strength of the shelf device may be reduced.

An object of the present invention is to enable a shelf plate to be attached efficiently without reducing the strength of the shelf device.

[0007]

In order to achieve this object, the shelving device of the present invention is provided with "a plurality of shelves arranged in parallel along the traveling direction of the moving carriage, and a traveling path of the moving carriage among the shelves. A beam-shaped front support frame that extends along the traveling direction of the carriage to support the front edge that is located closer to it, and a rear edge that is located on the opposite side of the shelf from the travel path of the carriage, to move. A beam-shaped rear support frame extending along the traveling direction of the trolley, and a front end edge of the shelf board is placed on the front support frame, while a rear end edge of the shelf board is fitted to the rear support frame from the front. Form a forward facing opening groove, insert the rear edge of the shelf into this forward facing opening groove, and in that state support the shelf board immovably back and forth with the front and rear support frames, and A fixing member that is set so that there is a gap between it and the upper surface of the shelf plate, and that holds the shelf plate upward and immovable in the gap. And to the structure of the plug is attached ".

[0008]

According to this structure, the front end edge of the shelf board is supported by the front support frame in a state where the rear end edge of each shelf board is inserted into the front opening groove of the rear support frame, and then the fixing member. The shelf plate can be attached by a very simple procedure of inserting the above into the front opening groove of the rear support frame while being applied to the upper surface of the shelf plate.

In this case, since the rear end edge of each shelf plate is held so as not to move up and down by the fixing member fitted in the front opening groove of the rear support frame, the shelf is fixed in a loose state. . Further, since it is not necessary to form holes for attaching shelf plates in the front support frame and the rear support frame, the strength of the front and rear support frames does not decrease. Also, since the front edge of the shelf board fits tightly on the step of the front support frame, and the rear edge of the shelf board fits tightly on the front opening groove of the rear support frame,
The shelf plate and the front-rear support frame are in the same state as being integrally joined, in other words, the respective shelf plates and the front-rear support frame are in a state of reinforcing each other, and as a result, the front-rear support frame. The strength of the shelving device can be remarkably improved without increasing the wall thickness.

Therefore, according to the present invention, there is an effect that the shelving device of the automatic warehouse can be efficiently assembled without impairing the strength. Further, since it is not necessary to perform processing such as punching on the front support frame and the rear support frame, it is extremely easy to replace the shelf boards with those having different width dimensions. Further, according to the second aspect of the invention. Since the fixing member also serves as a guide member (or a shelf partitioning member) for luggage, the structure of the shelf device can be simplified accordingly. Further, since the four members including the shelf adjacent to the fixing member and the rear support frame are in a state of reinforcing each other, the strength can be further improved.

Has been formed. In the present embodiment, the rail 2 also serves as a front support frame that supports the front edge of the shelf plate 16.

As shown in FIGS. 4 (B) and 6, the rails 2 are fixed to the front faces of the front columns 17 adjacent to each other with bolts 18. In this case, the rail 2 is arranged at each position between the adjacent front columns 17, and the positioning piece 19 formed at the end of the rail 2 is fitted into the positioning hole 20 formed in the front surface of the front column 17. The bolts 18 are fastened in that state. When formed in this way, the space between the adjacent front columns 17 is automatically set by the rails 2, which has the advantage of facilitating the assembly of the automated warehouse.

The rear end edge of each shelf 16 is supported by a rear support frame 21 made of a metal plate extending parallel to the rail 2. The rear support frame 21 is also set to have the same length as the rail 2, as shown in FIG.
As shown in (B), the end of the bolt 1
It is concluded with 8. The front and rear columns 17 and 22 are erected at regular intervals along the traveling direction of the mobile trolley 1, and a plurality of sheets are provided in each of the storage areas 3a, with the location between the adjacent columns 17 and 22 as one storage area 3a. The shelf boards 16 of are arranged side by side.

As shown in FIGS. 4A and 7, the rear support frame 21 has a front opening groove 23 that opens toward the rail 2.
Is formed, and the rear end edge of the shelf 16 is inserted into the front opening groove 23. In this case, the upward opening U-shaped fitting portion 21a is formed at the front edge of the front opening groove 23 of the rear support frame 21, while the rear edge of the shelf board 16 is
The rear foot piece 16b having an L-shaped cross section is formed by bending, and the rear foot piece 16b is fitted into the fitting portion 21a of the rear support frame 21 so as not to be displaced forward and backward.

The front opening groove 23 of the rear support frame 21 has a gap 2 between the upper surface of the rear support frame 21 and the upper surface of the shelf 16 at a certain distance.
4 is set to such a height that the gap 24
, The fixed end of the fixing member 25, which is overlapped over both of the adjacent shelves 16, is tightly inserted, whereby each of the shelves 16 is held in a vertically immovable state.

At the upper end of the rear support frame 21, a stopper piece 21b for preventing the luggage W from falling is provided so as to project upward. As shown in FIG. 4 (A) and FIG. 5 (A), the fixing member 25 is formed so as to extend long along the depth direction of the shelf 3, and the luggage W is laterally offset on both longitudinal edges thereof. To prevent the guide part 25 protruding upward.
A is formed so as to extend over the entire length, and the rear end portion of this guide portion 25a is inserted into the gap 24 in a tight state. The front end portions of both guide portions 25a are inclined toward the center line so as to have a C shape in a plan view.

As shown in FIGS. 4 (A) and 5, the lower surface of the fixing member 25 at a plurality of locations (3 locations) along the longitudinal direction is oriented laterally in the direction of the center line of the fixing member 25. A pair of hook-shaped engaging claws 26 extending in the vertical direction are cut and raised one by one. On the other hand, the engaging claws 26 are provided on the side edges of each shelf plate 16.
The engaging hole 27 corresponding to the above is formed, and the engaging hole 27 and the engaging claw 26 constitute the engaging means described in claim 2.

The engaging hole 27 is composed of a wide portion 27a into which the engaging claw 26 can be vertically fitted and removed, and a narrow portion 27b in which the engaging claw 26 cannot be removed. By inserting the engaging claw 26 into the wide portion 27a, the fixing member 25 is superposed on the shelf board 16, and in that state, the fixing member 25 is slid toward the front opening groove 23 of the rear support frame 21 to be fixed. Member 25
The rear end edge of the guide portion 25a in the above is fitted into the front opening groove 23 of the rear support frame 21, and the engaging claw 26 is engaged with the engaging hole 27.
The fixed member 25 and the shelf plate 16 adjacent to each other are in a state of being coupled to each other.

The groove width dimension of the narrow width portion 27b in the engaging hole 27 is set to be somewhat larger than the wall thickness dimension of the engaging claw 26. Therefore, even if there is an error in the width dimension of the shelf board 16, the error can be absorbed and the shelf board 16 can be reliably attached. As shown in FIGS. 5 (A) and 5 (C), a dowel 28 extending diagonally forward is cut and raised downward at a portion of the fixing member 25 before each engaging claw 26 so as to project downward. When the fixing member 25 is fully slid toward the rear support frame 21, as shown in FIG. 8 (B), the dowel 28 is fitted and engaged with the front end edge of the engagement hole 27 in the shelf board 16, The fixing member 25 is held so that it cannot be pulled out forward.

As shown in FIG. 9, the fixing member 25 located at the end of each storage area 3a has its side surface on the front and rear columns 22.
Is set so as to hit the center line, and only half of the center line is overlapped with the shelf plate 16. In this case, since the fixing member 25 at the end portion is also held upward with respect to the shelf plate 16 so as not to be pulled out, the fixing member 25 drops even if there is a gap between the shelf plate 16 and the columns 17 and 22. Therefore, each of the shelves 16 is held so as not to be displaced laterally.

In mounting the shelf board 16 in the above structure, first, the rear end edge of the shelf board 16 is inserted into the front opening groove 23 of the rear support frame 21, and then the front end edge is set on the step portion of the rail 2. 2a, and then placed, and then FIG.
As shown in (B), the extremely simple procedure of sliding the fixing member 25 toward the rear support frame 21 with the fixing member 25 in contact with the upper surface of the shelf plate 16 is sufficient. Therefore, the shelf frame 4 can be assembled efficiently.

Further, since the rail 2 and the rear support frame 21 are made of a metal plate, if the wall thickness is thin, an arrow A in FIG.
As shown in FIG. 3, the rail 2 can be easily bent and deformed about the axis, but in the present invention, the rail 2 is fitted with the front end edge of the shelf 16 tightly with the step portion 2a of the rail 2. The rear end edge of the rail 2 and the rear end edge of the fixing member 25 are fitted into the front opening groove 23 of the rear support frame 21 while being prevented from being deformed so as to be twisted about the axis, Since the rear support frame 21 is prevented from being deformed so as to bend around its axis, the strength of the shelf frame 4 can be improved without making the rail 2 and the rear support frame 21 thick.

Further, when the fixing member 25 is structured as in the embodiment, the shelf plate 16, the fixing member 25 and the rear supporting frame 21 which are adjacent to each other are connected to each other. There is an advantage that the strength of the frame 4 can be further improved.

As in the embodiment, when the fixing member 25 located at the end of each storage area 3a is applied to the side surfaces of the columns 17 and 22, the shelf board 4 can be attached without rattling. Since each of the shelves 16 and the fixing member 25 can be standardized into one type, the manufacturing cost can be reduced and the labor for mounting can be reduced. Further, by fitting the rear foot piece 16b of the shelf plate 16 into the fitting portion 21a of the rear support frame 21, it is possible to reliably prevent the shelf board 16 from being displaced, and the rear foot piece 16b and the fitting portion 21a are exactly overlapped with each other. Since they reinforce each other, there is an advantage that the strength can be improved.

As shown by the chain double-dashed line in FIG. 3, the movable frames 12 and 13 of the movable carriage 1 are fixed to the fixed member 2.
It is set so as to move back and forth in the shelf 3 at a position above 5. With such a configuration, even if the load already placed on the shelf 16 is displaced due to an earthquake or vibration, the moving frames 12 and 13 will not hit the load W in the next transfer work. You can do it safely. Further, since the moving frames 12 and 13 move forward and backward above the fixed member 25,
Space can be used effectively.

In this embodiment, the step portion 2 formed on the rail 2 is used.
Although the forward displacement of the shelf board 16 is prevented by a, and the shelf board 16 is held by the rear support frame 21 so as not to move backward, for example, the front end edge of the shelf board is formed in a downward U-shaped section. By fitting this on the front support frame, the shelf plate may be held so as not to move back and forth. Further, as a means for supporting the shelf board 16 by the rear support frame 21, as shown in FIG. 10, the rear foot piece 16b of the shelf board 16 is bent in an upward opening C shape, and the rear support frame 21 is fitted thereto. You may fit in the joint part 21a exactly.

Further, as shown in FIG. 11, the rear foot piece 16b of the shelf 16 may be supported by the leading edge of the fitting portion 21a of the rear support frame 21. With the support form of FIG. 10,
There is an advantage that the looseness of the shelf plate 16 and the fixing member 25 can be absorbed by utilizing the flexural deformation of the rear foot piece 16b. Further, in any of the supporting forms, the rear support frame 21 can be slightly bent and deformed against the elasticity by the insertion of the fixing member 25. Therefore, the elastic restoring force of each shelf plate 16 does not rattle. Can be fixed to the presser foot.

Although the above embodiment is applied to the automatic warehouse of the type in which the movable carriage travels only horizontally on the rails, the present invention is applicable only to the stacker crane type automatic warehouse and the vertical movement. It goes without saying that the present invention can also be applied to other types of automated warehouses, such as a type of automated warehouse that uses a lift type trolley to transfer luggage to a shelf.
