BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to rotary shelving equipment used, for example, in factories to store and manage long items such as aluminum blind frame materials. [0002]

[Prior Art] Conventionally, as for rotary shelving equipment, as shown in, for example, Japanese Utility Model Publication No. 59-23559, a driving wheel body and a driven wheel body are disposed with an interval in the horizontal direction (lateral direction). However, a configuration is provided in which an endless rotating body is wound between these wheels, a plurality of shelves (racks) are attached to the endless rotating body, and a plurality of upper and lower cargo receiving sections are formed in each column. [0003] Then, the shelf group is moved to stop the target shelf facing the material handling area, and the target shelf on this stopped shelf is sent to the department for the intended order picking work,
Alternatively, the cargo (including cases) itself is loaded and unloaded. [0004]

[Problems to be Solved by the Invention] According to the above-mentioned conventional system, when carrying a long object onto this shelf, the long object is first turned sideways and then carried into the receiving section. A large space was required in front of the vehicle to allow the long object to be placed sideways. For this reason, when installing shelving equipment, it was necessary to provide a sufficiently wide distance from peripheral equipment. [0005] Furthermore, when long items were stored on this shelf, one end of the long items protruded laterally outward from the cargo receiving section due to the short depth of the shelf. In addition, increasing the depth of the shelf requires increasing the strength of the wheels and guide rails that support and guide the shelf, and also increases the installation area of the entire equipment. [0006] Furthermore, the guide width of the guide rail in the curved part is the same as that in the straight part, and is slightly larger than the diameter of the guide wheel, so when the rack moves in the curved part, the guide wheel can run smoothly. However, a loss of driving force occurred. [00071 The object of the present invention is to easily and reliably store long objects on shelves without requiring a large space when transporting long objects, and to make the installation area of the entire equipment compact. Another object of the present invention is to provide a rotary shelving facility that can smoothly move a shelving truck on a curved path. [0008]

[Means for Solving the Problems] In order to achieve the above object, the rotary shelving equipment of the present invention has a lower surface side supported and guided by a lower rail, and a rear side supported and guided by an upper rail, so that the rotary shelf equipment has an endless, constant horizontal surface. A rotary shelf is constituted by a plurality of shelf carts that are movable on the route and a drive device that integrally moves these shelf carts forward and backward, and the guide width of the upper rail in the curved route portion of the constant water level route is adjusted. The shelf truck is formed to be wide, and the upper end of the shelf truck is higher than the upper rail,
In addition, openings are formed on the front and top surfaces, an elastic fastener is provided for pressing vertical long items against the back side, and a partition material is provided on the top and the top surface of the bottom plate to divide the storage space into a plurality of parts. Further, a member for preventing forward falling is provided in the front part of the upper end portion across the width direction. , rO009]

[Operation] According to the configuration of the present invention described above, the rotary shelf is moved and the target shelf cart is stopped at a predetermined position. At this time, since the guide width of the upper rail is formed to be wide in the curved route section, the shelf cart can smoothly move on this curved route section. [00101 After the shelf truck has stopped, when transporting a long item to the desired shelf truck, store the long item vertically from the front of the shelf truck, and place it against the back of the shelf with elastic tightening. Use a tool to press the attachment to the back side. When there are a large number of items to be stored, partitioning materials and materials to prevent the items from falling forward are used to prevent the items from shifting laterally or falling forward. [0011] When carrying out a long object, contrary to the above-mentioned case of carrying it in, the tightening tool can be removed and the long object can be taken out from inside the shelf while standing vertically. [0012]

A pair of left and right wheels 4 that are supported and guided by the lower rail 2 and are rotatable are disposed on the lower surface side of the bottom plate 24. A bracket 33 protruding from the rear vertical member 26B in the direction of the upper rail 3 is fixed to the middle part of the back side of the shelf truck 6, and a pair of left and right rollers 5 are provided via a shaft 34 erected from the top surface of the bracket 33. It is being This roller 5 is rotatably fitted inside the guide plates 21A, 21B of the upper rail 3. One end of an L-shaped member 35 is fixed to the upper end of the front vertical member 26A, and the other end is fixed to the upper end on the rear side of the opposing rear vertical member 26B. An upper rubber band 36 is attached between the vertical portions 35A on the back side of the side-curved member 35 via machine screws (not shown). Further, a forward fall prevention member 37 is installed between the upper ends of both front vertical members 26A, and this forward fall prevention member 37
An upper partition member 38 is installed at the center of the horizontal member 27, which is installed between the center of the rain rear vertical member 26B and the upper end of the rain rear vertical member 26B. [0017] Also, on the back side of the shelf truck 6 and slightly below the middle, a pair of upper and lower horizontal members 28 are installed between the rain rear vertical members 26B, and at the center and both left and right ends of these horizontal members 28, The longitudinal members 39,40 are connected between the cross members 28. Among these, one end of a lower rubber band 41 is attached to the upper and lower parts of the central vertical member 39 through machine screws (not shown), and a hook 42 is provided at the other end of the lower rubber band 41. There is. As a result, the lower rubber band 41 is connected to the left and right vertical members 40 through the hooks 42, respectively.

is erected, and this lower partition member 43 is located at the center of the shelf truck 6 in the width direction from the front side 31 to the rear side. Therefore, the storage space 44 is partitioned into right and left sides by the upper partition member 38 and the lower partition member 43. 45 indicates a long object stored in the storage space 44. [0019] Next, the operation of the above embodiment will be explained. To move the rotary shelf 1, the driving device 14 is actuated via the control device 15 by keyboard operation, and the endless rotating body 11 is moved.
This can be done by rotating forward and backward, thereby moving the 6 groups of shelf carts on a fixed path 13. That is, the shelf truck 6 is connected to the upper and lower rails 2 via the wheels 4 and rollers 5.
, 3 to move with support and guidance. [00201 At this time, as shown in FIG.
is supported and guided by the inner surface of the curved path section 1.
Move to 8. Guide width W1 of this curved path portion 18
is formed to be wider than the guide width W2 of the straight path portion 19, and the roller 5 is mainly moved by the outer guide plate 2 due to centrifugal force.
It is supported and guided while in contact with the inner surface of 1A, and can smoothly move along the curved path section 18. Then, the target shelf cart 6 is stopped at a predetermined position such as a loading/unloading location. [00211 After that, when transporting the long objects 45 to the target shelf cart 6, if the number of long objects 45 is small, the long objects 45A are erected vertically as shown by the imaginary line in FIG. Mama,
The upper end portion of the elongated object 45A is made to project from the front face 31 of the shelf truck 6 to the rear side of the shelf truck 6 through below the upper rubber band 36 and above the cross member 27. Then, the lower end of the elongated object 45A is carried onto the upper surface of the bottom plate 24 of the shelf truck 6, and placed along each of the cross members 27, 28, and 29 on the back side. As a result, the elongated object 45A is pressed against the inner back surface of the shelf cart 6 by the elastic force of the upper rubber band 36 in a vertically standing position, and is thus fixed and stored. [0022] Also, as shown in 45A to 45C of FIG.
If the number of long objects 45 is somewhat large, the innermost long object 45A
is fixed to the inner back surface of the shelf truck 6 using the upper rubber band 36 as described above. As for the long objects 45B and 45C that are closer to the long object 45A than the long object 45A, as shown by the imaginary line in FIG. , as shown by the solid line in FIG. 6, the hook 42 is hooked onto either one of the left and right vertical members 40. As a result, the long objects 45B and 45C are moved to the shelf cart 6 by the lower rubber band 41 along with the long objects 45A.
It is fixed and stored by being pressed against the inside back of the [002,3] Also, the long objects 45 are 45A to 45C in FIG.
If there are a large number of objects compared to the above, use the upper rubber band 36 for the long object 45A at the far end, and use the lower rubber band 41 for the long objects 45B and 45C several rows from the back. It is used to fix and store the respective long objects 45A to 45C, and to store the other long objects 45D and 45.
As for E, as shown by the imaginary line in FIG. 1, it is stored inside the shelf cart 6 while standing vertically. These long objects 4
5D and 45E are not fixed by the upper and lower rubber bands 36 and 41, so when they are about to fall forward, they are supported by the forward fall prevention member 37 to prevent them from falling forward and prevent them from shifting laterally. When the upper and lower partition materials 38.43
This prevents further lateral displacement. [00241] When carrying out the long object 45 from the target shelf cart 6, it is sufficient to lift the long object 45E in front while standing vertically and take it out from the front 31 of the shelf cart 6, contrary to the case when carrying it in. Also, a long object 4 fixed with a lower rubber band 41
5B and 45C, after removing the hooks 42 of the lower rubber band 41 from the left and right vertical members 40,
Take out 5B and 45C. [0025] Regarding the long object 45A fixed by the upper rubber band 36, lift the long object 45A once and take out its lower end to the front of the shelf cart 6, and then move the upper end to the bottom of the upper rubber band 36. reduce. Then, by taking out the upper end of the elongated object 45A from below the upper rubber band 36 to the front of the shelf truck 6, the elongated object 45A is carried out. [0026] In the above embodiment, rubber bands 36 and 41 are used as the elastic tightening device, but this may also be a plate spring, a coil spring, or the like. In addition, in the above example, the partition material 38.43
are provided at one location at the top and bottom of the shelf truck 6 from the front 31 to the rear, but they may be provided at multiple locations.
Furthermore, they may be provided in the left and right direction of the shelf truck 6. [0027] In the above embodiment, the shelf cart 6 is supported and guided by the upper rail 3 via the rollers 5, but a pin or the like may be used instead of the rollers 5. [0028]

[Effects of the Invention] According to the present invention having the above-mentioned structure, by forming the shelf cart in a vertically elongated shape and forming openings on the front and top surfaces thereof, long objects can be carried into and out of the shelf cart while standing vertically. This eliminates the need for the large space required to fold long objects sideways as in the past, allowing for loading and unloading in a narrow space. [0029] Also, this shelf cart can easily store a large number of long objects in a vertical position; some of the long objects are fixed with elastic fastening tools, and other long objects are fixed with elastic fastening tools. It is prevented from tipping over or shifting by using the front tipping prevention material and the partitioning material. Therefore, there is no longer a problem where long items cannot be stored completely due to the short depth of the shelf, and one end of the item protrudes outward from the side of the shelf. , the installation area of the entire equipment becomes compact. [00303 Furthermore, the above-mentioned elastic tightening is achieved by providing tools, materials to prevent forward tipping, and partition materials, so that while the shelf cart is moving,
It is possible to prevent long objects from falling or shifting due to centrifugal force, vibration, etc., and safety during loading/unloading work is ensured. [00311 By forming the guide width at the curved path portion of the upper rail to be wide, the shelf truck can smoothly move along this curved path portion. Therefore, movement loss is reduced and the load placed on the drive device is reduced, so the operating cost of the shelving equipment can be reduced.
