Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a storage shelf equipped with a rail frame that transfers stored goods (baggage) using gravity, and particularly relates to a storage shelf equipped with a rail frame that uses gravity to transfer stored goods (baggage), and in particular, This relates to a structure in which a cantilevered rail frame is removably locked to the rail frame.

[Conventional technology]

Storage shelves used in warehouses, etc. usually have a structure in which a rail frame with a large number of rollers (or wheels) is attached to the shelf frame in order to transfer loaded (placed) products to the cargo side using gravity. It becomes.

As the above-mentioned mounting structure, the one shown in FIG. 25 is conventionally known. In the illustrated mounting structure, the rail frame 5 is attached to the shelf frames 3, 3. ... and the end frames 21.2 are placed perpendicular to the rail frame 5, and both ends of the rail frame 5 are placed perpendicular to the end frames 21.2.
1 to the shelf frame 3.3.

[Problem that the invention seeks to solve]

However, the conventional storage shelves mentioned above use end frames with a special shape, which makes the structure complicated and expensive. Can not do it. That is, as shown in FIG. 24, for example, JP-A-59-20730
By the automatic picking device 22 disclosed in Publication No. 4,
Even if unloading is attempted, the end frame 21 will be in the way, so the tip of the swinging conveyor 23, 23 cannot enter between the rail frames 5, 5.

Therefore, it is conceivable to connect the rail frame and the shelf frame with bolts, bolts, etc. and make the downstream end of the rail frame protrude from the shelf frame so that the automatic picking device can be used.

However, even with such a mounting structure, there are disadvantages in terms of general use of automatic picking devices. In other words, stored products are usually stored in outer boxes such as cardboard boxes, and in order to minimize uneven deformation on the bottom of the outer box even during long-term storage, the rollers of the rail frame are designed with a large width. Since it is preferable to use a rail frame, the width of the rail frame must be increased, and therefore the interval between the rail frames must be narrowed. Therefore, in order to unload stored products by introducing the swinging conveyor of an automatic picking device between such rail frames, the interval between the swinging conveyors must be narrowed. If the interval is narrowed, it will be difficult to stably hold the stored products on the swinging container, and there is a risk that the stored products will fall.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a storage shelf that can be easily and reliably used with an automatic pinking device, and that can accommodate the transportation of products by gravity without causing problems due to deformation of the outer box.

[Means for solving problems]

The present invention includes a shelf frame and a rail frame attached substantially orthogonally to the shelf frame, and the rail frame has a large number of rollers or wheels on its upper surface and is mounted on the upper surface. In the storage shelf which is inclined so that loaded cargo can be moved by gravity, a cantilevered rail frame is located at the downstream end of the rail frame and is locked to the shelf frame via a locking structure. The locking structure includes a protrusion provided on one of the cantilevered rail frame and the shelf frame, and a protrusion provided on the other that locks the protrusion by gravity applied to the cantilevered rail frame. The above object has been achieved by providing a storage shelf characterized by having a locking part that provides a storage rack.

As shown in FIGS. 4 and 6, the cantilevered rail frame 7 is locked to the downstream end of each rail frame 5 through a locking structure. As shown in detail in the figure, each rail frame 5 has two shelf frames 3A at its downstream end.

3B are arranged in parallel in close proximity, and each cantilever type rail frame 7 is locked to both of these two shelf frames 3A and 3B via locking structures 8A and 8B, respectively. The locking structure 8A includes a locking portion 3a provided at the upper part of the downstream shelf frame 3A, and a protrusion 7a provided on the cantilevered rail frame 7 to be locked to the locking portion 3a. The locking structure 8B is composed of a locking portion 3b provided at the lower part of the upstream shelf frame 3B, and a protrusion 7b provided on the cantilevered rail frame 7 to be locked to the locking portion 3b. , the locking portions 3a and 3b are not provided so that the protrusions 7a and 7b are reliably locked by the force of gravity applied to the cantilevered rail frame 7, respectively.

To explain the locking structures 8A and 8B in more detail, the locking portion 3a in the locking structure 8A is located on the shelf frame on the downstream side, as shown in FIG. 1O, FIG. 1), FIG. 12, and FIG. A plurality of holes are formed at regular intervals along the length direction of the shelf frame 3A on the top surface (thickness t) of the locking fitting 31A, which has a downward U-shaped cross section and is fixed to the top of the shelf frame 3A. , each of the planar shapes is approximately trapezoidal (height h) with its upper side (length β) facing downstream (toward the front side of the storage shelf). Further, the locking portion 3b in the other locking structure 8B is
It is formed in the same manner as the above-mentioned locking part 3a, except that it is provided on the lower surface part (JIJ-mit) of the locking metal fitting 3'lB, which is fixed to the lower part of the upstream shelf frame 3B and has an upwardly U-shaped cross section. It is. The locking portions 3a and 3b are provided a distance apart from each other in the front-rear direction of the storage shelf.

On the other hand, the protrusion 7a in the locking structure 8A is a bent flat metal fitting with a substantially J-shaped cross section, as shown in FIGS. 6, 7, 8, 9, 14, and 15. It is formed with
Such a metal fitting is fixed to the rear part of the lower side of the cantilevered rail frame 7 with the gap formed inside the folded portion directed toward the front of the cantilevered rail frame 7. As shown in FIGS. 14 and 15, the distance between the above-mentioned gaps is determined by the distance between the upper surface of the locking fitting 31A in order to lock the cantilevered rail frame 7 in a manner that it cannot swing in the vertical direction. In addition, in order to lock the cantilevered rail frame 7 so that it cannot swing in the left-right direction, the width of the metal fittings is made equal to the length l of the upper side of the locking portion 3a having a substantially trapezoidal planar shape. Furthermore, in order to easily insert the folded part of the protrusion 7a into the locking part 3a from above when locking the cantilevered rail frame 7, the outer end length of the folded part is set to the above-mentioned shape having a substantially trapezoidal planar shape. The length h' is smaller than the height h of the locking portion 3a. The protrusion 7b of the other locking structure 8B is attached to the rear end of the mounting bracket 71 fixed to the rear end of the cantilevered rail frame 7 and bent backward and downward.
It is fixed at a distance #1L equal to the distance between the locking portions 3a and 3b rearward from a. Its cross-sectional shape is approximately J-shaped like the projection 7a, and
Its dimensions are the same as those of the projection 7a.
It does not have to be locked to the corresponding locking part 3b for the same purpose as the above.

In addition, each of the cantilevered rail frames 7 has protrusions 7a and 7b as described above, and also has an upper surface as shown in FIGS. 4, 6, 7, 8, and 9. A large number of rollers 9, 9. ... (not shown in Fig. 7), and a stopper 10 (no. 9 (not shown in the figure) are provided respectively.

And, the low -79,9°... of each cantilever type rail frame 7 is the roller 6,6°... of each rail frame 5.
Correspondingly, the width of each cantilever type rail frame 7 is made narrower than the width of each rail frame 5, and the width of each cantilever type rail frame 7 is made narrower than the width of each rail frame 5.
7 so that the swinging conveyor of the automatic pinking device can easily enter the space.

Therefore, each cantilevered rail frame 7 in the storage shelf configured as described above is locked by connecting the rear part of each cantilevered rail frame 7 to the downstream shelf frame 3A and the upstream shelf frame 3.
After inserting it from above between the two cantilevered rail frames 7, the tip of each cantilevered rail frame 7 is rotated forward, and the projections 7a and 7b of each cantilevered rail frame 7 are inserted into the corresponding shelf frame 3.

Therefore, since a load from above acts on the shelf frame 3A on the downstream side, and a load from below acts on the shelf frame 3B on the upstream side, each cantilever type rail frame 7 is stably supported. Moreover, in this case, the products stored in the stopper 10 4.4. Because each cantilevered rail frame 7 is constantly pulled forward due to the pressing action of..., the above-mentioned protrusions... a, 7b and the shape and dimensions of the locking parts 3a, 3b, the protrusion 7a,
7b are reliably locked to the locking portions 3a and 3b, respectively, and as a result, each cantilever type rail frame 7 is reliably supported so that it cannot swing or come off. Furthermore, if a narrow cantilever rail frame 7 is used as the protruding and supported cantilever rail frame 7, the swinging conveyor of the automatic bifking device can easily enter the pair of adjacent cantilever rail frames 7.7. This makes it possible to reliably prevent stored products from falling from the swinging conveyor when unloading using an automatic picking device. Furthermore, in this case, each rail frame 5 can be made of a wide one, so that deformation of the outer box of the stored product can be prevented, and deformation of the outer box can prevent problems in transporting the product due to gravity. It can be done. Furthermore, each cantilevered rail frame 7
The locking positions of the protrusions 7a and 7b are the shelf frames 3A and 3.
Since the holes can be arbitrarily selected from a large number of holes drilled at regular intervals along the length direction of B, stored products 4, 4. ... can be easily changed according to the size of stored products 4, 4. It is possible to efficiently operate the storage shelves that match the size of the stored products 4, 4, etc., and the intervals between the swinging conveyors of the automatic picking device are widened. It is also possible to stabilize and hold...
