Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a three-dimensional automatic warehouse in which stored items are automatically stored in one of a plurality of storages using a stacker crane. This invention relates to a multi-story warehouse equipped with a fixing device to prevent stored items from falling over.

[Prior Art] Conventionally, three-dimensional automatic warehouses as shown in FIGS. 7 and 8 have been provided as three-dimensional warehouses that can store a large number of items in a small space.

The three-dimensional automatic warehouse shown in these figures is a three-dimensional warehouse 2 in which a plurality of storage warehouses 1, 1... are installed in multiple rows and multiple stages.
, Statzker Crane 3 and Traverser 4
The main components are:

This multi-level automated warehouse is constructed by moving the stacker crane 3 along the multi-level warehouse 2, raising and lowering the loading platform 5 of the stacker crane 3, and extending and contracting a slide fork (not shown). It is constructed so that the storage can be entered and taken out between the storage racks 6, 6 and the storage racks 1, 1, . . . , which are all automatically operated. The traverser 4 moves the stacker crane 3 in the directions of arrows A and B in FIG.

By the way, the multi-dimensional warehouse 2 used in the above-mentioned multi-dimensional automated warehouse is configured by arranging as many storage compartments 1 as possible in order to effectively utilize the space of the factory.

However, in the above-mentioned multi-story warehouse 2, each storage 1 is constituted by a box-shaped frame having a bottom plate 7, so when the stored items are relatively small such as drums, an extremely large amount of storage space is required. There was a problem in that the storage 1 had to be constructed, which increased production costs such as material costs and construction costs, making it relatively expensive.

Moreover, in the multi-story warehouse 2, the stored items 8 are placed and stored on the top surface of the bottom plate 7 of the storage 1 with the front side open. If you store items that have casters attached to them for transport, or items that are elongated and unstable, there is a risk that the items will slip or fall.

Therefore, a warehouse as shown in Utility Model Application Publication No. 58-166507, for example, has been proposed as a system that can prevent even the unstable stored items mentioned above from falling out of the storage warehouse.

As shown in FIGS. 9 and 10, the warehouse according to the above proposal has two stoppers 11, 11 removably installed at the entrances of storage compartments 10, 10, which are installed in plural on both sides of the trolley passage 9. The movable trolley 12 and each storage 10, 10
After inserting the stored item 14 into the storage 10 by sliding the rollers 13, 13 provided on the upper surface thereof, the stored item 14 is inserted into the storage 10 by attaching the stoppers 11, 11 to the entrance of the storage 10. This prevents the person from slipping down.

In particular, in the above-mentioned warehouse, workers
A safety device is provided to prevent the stopper 11 from being accidentally removed at times other than when entering and exiting the warehouse. That is, a cylindrical case 15 is provided on the side of one of the stoppers 11. A slider 16 is provided within the case 15 so as to be movable in the longitudinal direction. This slider 16 is biased in the direction of arrow C in the figure. An engagement piece 17 is fixed to the slider 16 so as to protrude toward the stopper 11 side. on the other hand,
A recess 11a that engages with the engagement piece 17 is formed at the lower end of the stopper 11. moreover,
A shaft 18 is supported on the side of the movable cart 12 so as to be movable in the longitudinal direction. This shaft 18 positions the movable cart 12 by inserting its tip into the slider 16, and also moves the slider 16 in the direction of arrow D in the figure to release the engagement between the stopper 11 and the slider 16. It is for.

In a warehouse with the above configuration, not only can stored items be prevented from falling, but also
The stopper 11 is activated when the stored items 14 are not being loaded or unloaded.
Since the stopper 11 cannot be removed, the stopper 11 will not be removed due to an operator's mistake, and it is possible to more effectively prevent stored items from falling off.

[Problems to be Solved by the Invention] By the way, in the above-mentioned warehouse, a stopper is removably arranged at the entrance of a storage compartment arranged flat on the floor of the factory, and the stopper is attached and detached manually. Because it is configured as
It is not possible to prevent stored items that are vertically long and have poor stability from falling over. Moreover, if the stored item is, for example, a radioactive material, it must never be overturned, so even if the stored item is vertical and unstable, it can be fixed securely in the storage compartment. It would also be a good idea to provide a multi-storey warehouse where this can be done.

However, the reality is that such three-dimensional warehouses are not currently available.

This invention was made in view of the above circumstances, and can be applied to stored items of any shape.
Stored items can be securely fixed in the storage compartment,
Furthermore, the purpose of this invention is to provide a three-dimensional warehouse that can be manufactured at low cost even when storing relatively small items such as drums.

[Means for Solving the Problems] In order to achieve the above object, the present invention has the following configuration. That is, the multi-story warehouse of the present invention has a plurality of pillars that are erected at a distance from each other in the horizontal direction, and the opposite sides of the adjacent pillars are made to protrude laterally in the horizontal direction, and a constant distance is provided between the opposite ends. a fixing device that is provided between the two pairs of upper and lower supports and fixes a stored item placed between the upper surfaces of the pair of opposing supports; The fixing device is positioned above the supporting device and supported by the column so as to be movable in the vertical direction,
The mounting plate is urged upward by an elastic member, and the mounting plate is connected to the mounting plate so as to move up and down at the same time as the mounting plate, and is rotatably supported so as to be positioned above the mounting plate. , a pair of rotary arms biased by an elastic member such that the end on the side in the insertion direction of the stored item is closed closer than the front end; and a pair of rotary arms provided between the column and the rotary arm, and It is constructed from a stopper mechanism that engages with each other to prevent rotation of the rotary arm when the above-mentioned stored items are placed on the plate and the plate is lowered.

[Embodiment] FIGS. 1 to 6 are diagrams showing an embodiment of the present invention.

The three-dimensional warehouse shown in these figures is for fixed storage of vertically cylindrical objects, as an example.

In FIG. 1, the symbol A is a multi-storey warehouse.

This multi-storey warehouse A is similar to the multi-storey warehouse 2 shown in FIG. 7 described in the conventional example, in which a plurality of storage sections are arranged in multiple rows and multi-tiers and in two layers back to back, and is constructed as follows. There is. That is, in the figure, reference numeral 19 is a pillar. The pillars 19 are fixed at both ends to the upper and lower frames 20 and 21, respectively, and are arranged in a row in the left and right direction at a constant interval. (in the direction perpendicular to the page in FIG. 1). As shown in Figs. 2 and 3, beams 22, 22... are installed vertically at regular intervals between these pillars 19, 19, which face each other in the front-rear direction. There is. A girder member 23 is installed between the upper and lower beams 22, 22, and the girder members 23, 2 adjacent to the left and right
3 has a stopper 24 installed thereon.

Further, a support 25 is fixed at a position corresponding to the beam 22 on opposing side surfaces 19a, 19a of the pillars 19, 19 adjacent in the left and right direction. Here, as shown in FIGS. 2 and 3, the pair of opposing supports 25, 25 are spaced apart from each other at a distance large enough to allow a fork 42 of a stacker crane 41, which will be described later, to pass between their ends. installed. Furthermore, the adjacent beam 2
On the opposing sides 22a, 22a of 2, 22,
Auxiliary supports 26, 26 are fixed to match the height of the support 25.

The support 25 includes a rectangular plate 27 on which stored items are placed, and substantially triangular ribs 28, 28 that support the plate 27. It should be noted that the auxiliary support 26 is also configured in the same manner as the support 25, so its explanation will be omitted.

Two pairs of upper and lower supports 25 configured in this way,
25; A fixing device for fixing stored items is provided between 25 and 25. To explain the fixing device, support plates 29, 29 are provided at both ends of the upper and lower surfaces of the beam 22 so as to be perpendicular to the beam 22 in the longitudinal direction.
...is fixed. Further, a support plate 29a is similarly fixed to the side surface 19b of the column 19 facing rearward, and to the intermediate portion between the upper and lower beams 22, 22. Also, on both sides of the pillars 19, 19 facing each other in the front and rear, crosspiece members 30, 30 are installed vertically apart from each other. This crosspiece member 30 and the support plates 29, 29
A shaft body 31 is disposed through both ends of the support plate 29a so as to be movable in the vertical direction.

A spring seat 32 is fixed to an intermediate portion of the shaft body 31. And this spring seat 32 and the upper and lower beams 22,
Between the support plate 29a located in the middle of 22,
A spring (elastic member) 33 is provided for urging the shaft body 31 upward. In addition, two rotary arms 3 are provided in the middle part of the shaft body 31, spaced apart from each other in the vertical direction.
4 and 34 are loosely fitted, and each rotating arm 34
Fixtures 35, 35 are attached so as to sandwich them. Based on this configuration, each rotating arm 34, 34
rotates in the directions of arrows P and Q in FIG. 3 with respect to the shaft body 31, and can move up and down in the same manner as the shaft body 31.

The rotating arm 34, as shown in FIG.
It has an arc shape, and the radius of curvature of the inner circumference is slightly larger than the radius of the stored item, so that when the stored item is stored and fixed, there is a gap between the inner peripheral surface and the outer peripheral surface of the stored item. There will be some gaps. The tip of this rotating arm 34 (pillar 1
9 side end) is connected to the column 19 via a spring (elastic member) 36, and is biased in the rotational direction of arrow P so that its outer peripheral portion abuts against the side surface 19a of the column 19. There is. Further, at the other end of the rotating arm 34, a taper pin 3 having a tip protruding downward is provided.
7 is fixed. On the other hand, this taper pin 37
A pin receiver 38 that fits with the taper pin 37 is fixed to the upper surface of the crosspiece member 30 located on the lower side.

Further, at the lower end of the shaft body 31 and above the former support 25, a mounting plate 39 whose longitudinal direction is oriented in the left-right direction is loosely fitted. Fixtures 35, 35 are attached. The mounting plate 39 has its one end side surface in contact with the side surface 19b of the column 19, so that it does not rotate. This mounting plate 3
Reference numeral 9 is for storing stored items on its upper surface, and when this is lowered, the rotary arms 34, 34 are lowered together with the shaft body 31.

Based on the above configuration, the rotary arm 34 is rotated in the direction of arrow Q against the force of the spring 36 and lowered against the force of the spring 33, so that the taper pin 37 is fitted into the pin receiver 38. It is designed so that it is prevented from rotating.

In the multi-story warehouse with the above configuration, the stored items 4
0, first, as shown in FIGS.
and place it on the fork 42 of the column 19, 19.
The storage object 40 is held at a position in front of the intermediate portion thereof, such that the bottom surface of the stored object 40 is higher than the top surface of the mounting plate 39. Next, the fork 42 is moved to the multi-story warehouse side. Then, the side of the stored item 40 is rotated by the rotating arm 34.
The rotating arm 34 rotates in the direction of arrow Q against the force of the spring 36. Further, as shown in FIG. 6, the fork 42 is moved until the back surface 40a of the stored item 40 comes into contact with the stopper 24. In this state, the axis of the stored item 40 coincides with the center of curvature of each rotating arm 34, 34..., and the side surface of the stored item 40 coincides with the center of curvature of each rotating arm 34,
It is in contact with the inner peripheral surface of... Next, as shown in FIGS. 4 and 5, the fork 42 is attached to the support 2.
5, 25 and place the stored item 40 on each supporter 25, 25, 26, 26. Then,
The mounting plates 39, 39 are pushed down by the stored items 40, the rotating arms 34, 34... are lowered accordingly, and the taper pins 37, 37... are pushed down by the pin receivers 38, 34...
It is inserted into 38... As a result, each of the rotating arms 34, 34, . . . becomes unable to rotate in either the direction of arrow P or the direction of arrow Q, and the stored item 40 is fixed.

According to the three-dimensional warehouse of the above embodiment, the stored items 40 can be automatically fixed, and the supports 25, 25 on which the stored items are placed and the forks 42 do not interfere with each other, so that Since even vertically cylindrical stored items with poor stability can be securely fixed, accidents such as overturning and falling of stored items can be completely prevented.

Further, according to the embodiment described above, the positioning of the stored object 40 in the stored state can be performed reliably, so it is particularly effective when storing radioactive materials in which the distance between adjacent stored objects is strictly regulated. Furthermore, since the structure is simple and does not use actuators using hydraulic pressure, pneumatic pressure, etc., there is no possibility of failure, and the risk of workers being exposed to radiation due to maintenance and inspection can be completely eliminated.

Further, according to the above embodiment, since the stored items 40 are supported by the supports 25 fixed to the pillars 19, it is difficult to use the pillars 19 when storing relatively small stored items such as drums. To manufacture a three-dimensional warehouse at a low cost even when the storage capacity increases by allowing a large number of stored items to be stored centrally by simply setting short intervals between 19 and short vertical intervals between supports 25. Can be done.

Note that although the above embodiment is configured to store cylindrical objects, if the radius of curvature of the inner peripheral surface of the upper rotating arm is made smaller than that of the lower one, conical objects can be stored. can be stored. Furthermore, if the shape of the inner circumferential surface of the rotary arm is not limited to a circumferentially curved surface but is made into a swivel shape or the like, even when the cross-sectional shape of the stored object has various polygonal shapes, the stored object can be securely stored in a fixed manner.

[Effects of the Invention] As explained above, in this invention, a multi-story warehouse is provided with a plurality of pillars erected horizontally apart from each other, and a horizontally protruding lateral part on opposite sides of the adjacent pillars. A plurality of pairs of supports are provided above and below with a certain interval between the opposing ends, and a support device is provided between the two pairs of upper and lower supports, and is placed between the upper surfaces of the pair of opposing supports. and a fixing device for fixing stored items, and the fixing device is positioned above the lower support and supported by the column so as to be movable in the vertical direction,
The mounting plate is urged upward by an elastic member, and the mounting plate is connected to the mounting plate so as to move up and down at the same time as the mounting plate, and is rotatably supported so as to be positioned above the mounting plate. , a pair of rotary arms biased by an elastic member so that an end on the side in the insertion direction of the stored item is closer than the other end; and a pair of rotary arms provided between the column and the rotary arm, and It is composed of a stopper mechanism that engages with each other to prevent rotation of the rotary arm when the above-mentioned stored items are placed on the plate and the mounting plate is lowered, so that it can be attached to stored items of any shape. Even if it is a vertically cylindrical storage item with poor stability, it can be fixedly stored easily and reliably with a high consolidation rate, and even when storing relatively small items such as drum cans. The effect is that it can be manufactured at low cost.
