Description

[Detailed description of the invention] <Industrial application field> The present invention is a vertically movable shelf used in general stock shelves, tableware disinfection storage cabinets that store large quantities of tableware, cold storage cabinets, etc. This invention relates to a device for lifting and lowering members.

<Prior art> Conventionally, as a stock shelf for placing and stocking a large number of articles on a shelf board, a stocking device in which each shelf board is suspended from above by a chain or wire was developed in 1988-44807. It is proposed by the publication No.

When this storage device does not store items,
All the shelves are lowered and stacked, and each time a shelf is used to place an item, each shelf is raised in turn using a chain or wire to increase the number of items stored. It has a very good structure.

<Problems to be solved by the invention> However, although the edges of each shelf board are connected to four chains, etc. at regular intervals, the chains of each shelf board are almost completely irremovably connected. Therefore, there was a problem in that the interval between the shelf boards could not be easily changed depending on the size of the stored items. Also,
When the shelves are lowered and stacked, the chains and wires bend randomly on both sides of the shelves, resulting in an unsightly appearance, and the chain rings may get caught on other parts, such as the protrusions on the connecting parts. There was a risk that the shelves would not be able to rise horizontally.

The present invention was made to solve the above problems, and it is possible to easily change the attachment position of the shelf member to the belt-like or rope-like hanging device, and also to allow the shelf members to be lowered and stacked. It is an object of the present invention to provide a shelf member lifting and lowering device in which hanging tools can be bent in a certain direction to create an orderly state.

<Means for solving the problem> For this purpose, the shelf member lifting device of the present invention has a plurality of shelf members within a shelf frame, and at least four strip-shaped or rope-shaped hanging devices suspended from above. In a shelf member lifting and lowering device, the shelf members are arranged such that they can be raised and lowered by being supported at approximately four corners of each of the shelves, and are provided with a hoisting device for hoisting the hanging tools. The holding device is fixed to the shelf member, and the holding device is configured to impart bending directionality to the hanging device between the shelf members.

<Function> In this way, the belt-shaped or rope-shaped hanging tools that support each shelf member are pressed and fixed against the sides of the shelf members by the presser, and the hanging tools between each shelf member have a certain bending directionality. Because of this, when the shelf members are lowered and placed in a stacked state, the hangers between them bend only inward, creating an orderly state, and problems caused by disorderly bending are eliminated.

<Example> Hereinafter, an example of the present invention will be described based on the drawings.

Fig. 1 shows a front view of a shelf device having a shelf member 2 that can be raised and lowered, and Fig. 2 shows a right side view thereof. A plurality of members 2 are supported so as to be horizontally movable. There are four wire ropes 23a in the shelf frame 1.
Band-shaped hanging tools 3a to 3d are suspended from above by 23d, and substantially four corners of each shelf member 2 are connected to these hanging tools 3a to 3d at regular intervals. The hanging tools 3a to 3d are made of vegetable fibers, synthetic fibers,
A belt made of glass fiber or the like, a synthetic resin belt, or a plate spring can be used, and a belt that is flexible and can be elastically deformed to some extent is desirable.

Approximately four corners of each shelf member 2 are provided with four hangers 3a to 3d.
As shown in FIG. 3, hangers 3a to 3d hanging down from above are pressed and fixed to the pipe portion at the edge of the shelf member by a presser 4.
It is connected so as to extend downward. The holding tool 4 attaches bolts 16 to the pipe portion of the shelf member 2 so as to press the hanging tool onto approximately half the circumference of the pipe.
It is tightened and fixed. This holding tool 4 is made by bending a metal plate into a semicircular cross section so that the inner surface has approximately the same curvature as the outer peripheral curved surface of the pipe abutting part of the hanging tool, and bending the upper and lower edges slightly outward. A mounting hole for passing the bolt 5 is provided on both sides. In addition,
In order to prevent the hanging tool from slipping, the outer circumferential surface of the pipe and the inner peripheral surface of the hanging tool can be given a blank finish or an uneven finish.

In this way, hanger 3 is attached to the pipe part of shelf member 2.
Since parts a to 3d are fixed by pressure, the entry and exit sides of the hanging device following this fixed part will act to extend in the tangential direction of the pipe outer circumference as shown in Figure 5 if no vertical tension is applied. do. As a result, the hanging tools 3a to 3d between the upper and lower shelf members 2 are given bending directionality inward (inward direction of the shelf members).

The four band-shaped hangings 3a to 3d are connected to substantially four corners of the plurality of shelf members 2 as described above to horizontally support each shelf member 2, and the lower ends of each of the hangings 3a to 3d are connected to the shelf frame. Wire ropes 23a to 23d are fixed to the lower part of the shelf frame 1, and their upper ends are hung on the winding rollers 6 to 9 of the winding device 5 provided on the shelf frame 1.
are connected to each.

This hoisting device 5 horizontally supports one shaft 10 directly above hanging tools 3a and 3d located on the right side of the shelf frame 1, and has four hoisting rollers 6 to 9 on the shaft 10. The shaft 10 is connected by a chain and sprocket to a motor 11 with a reducer mounted on the shelf frame, and the motor 11 moves the shaft 10 to the first
It has a structure that rotates in the direction of the arrow in the figure. The hoisting roller 6 is located directly above the hanging tool 3a, the hoisting roller 8 is located directly above the hanging tool 3d, and the wire rope 23a connected to the upper end of the hanging tool 3a protrudes above the upper plate of the shelf frame 1. Immediately connected to the hoisting roller 6, the hanging device 3d
A wire rope 23d connected to the upper end of the winding roller 8 is similarly connected to the winding roller 8.

On the other hand, a wire rope 23 to the left on the shelf frame 1 in FIG.
Guide pulleys 12 and 13 are provided at the positions where b and 23c protrude above the upper plate, and the wire rope 23b is bent in the direction of the hoisting device 5 via the guide pulley 12. The wire rope 23b is bent in the direction of the hoisting device 5 through the wire rope 23b, and the tip of the wire rope 23b is connected to the hoisting roller 7, and the tip of the wire rope 23c is connected to the hoisting roller 9. hoisting rollers 6 and 7 of the hoisting device 5;
And since the winding rollers 8 and 9 are located close to each other,
It is also possible to form two grooves on the same roller. Further, a limit switch 14 is provided at the top of the shelf frame 1 to detect the rising end of the shelf member 2.
When the uppermost shelf member 2 reaches the rising end, the rod is pushed up and the limit switch 14 is activated by the rod.
Press this switch, and the hoisting device 5 is activated by the operation of this switch.
motor 11 is stopped.

In order to simplify the structure, guide rails for guiding the vertical movement of each shelf member 2 are not provided, but guide rails may be provided to prevent the shelf members 2 from shaking.

The shelf device configured in this manner is used, for example, when the shelf is not in use or when there are few stored items 15, with all the shelf members 2 positioned at the lowest position, as shown in FIG.

In this case, each of the hanging tools 3a to 3d is pressed and fixed to the pipe portion of each shelf member 2 from the outside by the holding tool 4, so when the hanging tools 3a to 3d are not tensioned, the bending direction is inward. hanging tools 3a to 3 between the shelf members 2 in a stacked state.
d are neatly bent inward as shown in FIGS. 2, 6, and 8. Therefore, the hangers 3a to 3d between the stacked shelf members may be bent in an unsightly manner, or the hangers bent outward may be caught between the shelf frame 1, or may be damaged by other members. There will be no problems such as sagging.

When placing many stored items, the hoisting device 5 is driven to rotate the hoisting rollers 6 to 9 in the counterclockwise direction in FIG. -9 to wind up and raise the shelf member 2. By hoisting up the hanging tools 3a to 3d, the shelf members 2 are pulled up in order from the upper tier, and when two tiers of shelf members are used, the shelf members 2 are in a state as shown in FIG. 8. In this case as well, since the stored items 15 can be placed on the shelf member at a low position, it is easy to take in and take out the stored items.

If you want to put more items on the shelf,
Similarly to the above, the hoisting device 5 is driven to raise the shelf members 2 in order, and the stored items 15 are placed in order on the newly spaced lower shelf members 2,
If the uppermost shelf board 2 is raised until it reaches its upper limit, all the shelf members 2 can be used to place the stored items 15, as shown in FIG.

When taking out the stored item 15, perform the operation opposite to the above, and start taking out the stored item at the lowest level.As the stored item 15 is taken out, the hoisting device 5 is rotated in the opposite direction, and the lifting devices 3a to 3d, that is, by unwinding the wire ropes 23a to 23d and lowering the shelf member 2 in order, the position for taking out the stored items 15 is always at the lowest level, and the taking out operation can be easily performed.

Therefore, even if the height of the shelf is increased, the number of items stored
5 can be easily put in and taken out.

On the other hand, when changing the height position of the shelf member 2, that is, the vertical interval, loosen the bottle 16 and
This can be easily done by shifting the fixing position to the shelf member 3d, and the hanging tool will hardly be damaged even if the position of the shelf member 2 relative to the hanging tool is changed, making it possible to use the band-shaped hanging tool for a long period of time. can do.

FIG. 10 shows another embodiment of a hanger between shelf members, in which a flexure 24 is attached to the intermediate portion of the hanger. This bending element 24 surrounds the hanging tool and is formed in a substantially dogleg shape, and is
acts to slightly bend the Therefore, when the elasticity of a hanging device such as a belt is poor and it is difficult to impart bending directionality to the hanging device with only a presser, by attaching this bending element 24, the hanging devices 3a to 3d
It is possible to reliably impart bending flexibility to the material.

11 and 12 show other embodiments of the shelf member, and the shelf member 32 in FIG. 11 is made of a square pipe,
Furthermore, the shelf member 33 in FIG. 12 is formed by bending the edge of a metal plate, and band-shaped hangers 3a to 3d are pressed against the sides of the shelf members 32, 33 by a presser 34 having a substantially trapezoidal cross section, and bolts It is tightened and fixed by. The holding tool 34 also imparts inward bending directionality to the hanging tool, and when the shelf members 32 and 33 are lowered, the hanging tool is bent inward.

In addition, the above-mentioned hoisting wire rope 23a~
23d may be a chain or a rope, or the belt-shaped hanging devices 3a to 3d may be extended as they are to a hoisting device and wound onto a hoisting roller.

FIG. 13 shows yet another embodiment, in which wire ropes 23a to 23a used in the hoisting device 5 are shown.
23d can be used as is as a hanging tool. That is, hanging tools, that is, wire ropes 23a to 23d hanging down from above, are pressed and fixed to the pipe portion at the edge of the shelf member 2 by the presser tool 4, and are connected so as to extend downward. As described above, the holding tool 4 is made by bending a metal plate into a semicircular cross section so that the inner surface has approximately the same curvature as the outer peripheral curved surface of the pipe abutting part of the hanging tool, and the upper and lower edges are bent. It is constructed by bending it slightly outward and providing mounting holes on both sides for passing the bolt 16, but by making a slight dent in the part where the wire rope 23a passes, and applying blank processing or thin uneven processing there, It is also possible to prevent the wire rope 23a from slipping and to stably fix it. Such a presser 4 is pressed against the side of the shelf member 2, and a reinforcing plate 19 is applied from the opposite side,
It is tightened and fixed with two bolts 16.

In addition, the wire ropes 23a to 2 as hanging devices
For 3d, a flexible rope that can be elastically deformed to some extent, such as a rope with a core material made of a thin wire covered with fibers, can also be used.

In the embodiment shown in FIG. 13 as well, the wire ropes 23a to 23d are press-fixed to the pipe portion of the shelf member 2, as in the above embodiment, so the wire rope 23a is located between the upper and lower shelf members 2. ~2
3d is provided with bending directionality so as to extend in the connection direction of the pipe outer periphery when no vertical tension is applied. As a result, when all the shelf members 2 are lowered to the lowest position, the wire ropes 23a to 23d are neatly bent inward between the stacked shelf members 2.

<Effects of the invention> As explained above, according to the shelf member elevating device of the present invention, the belt-like or rope-like hanging tool for suspending the shelf members is pressed against the side of each shelf member by the presser. The hanging tools between the shelf members are fixed in place, and the holding tools are used to impart bending directionality to the hanging tools between the shelf members. Therefore, when the shelf members are lowered and stacked,
The hanging tools between the shelf members are bent in a certain direction and arranged in an orderly manner, and problems such as the hanging tools being pinched between other members or tangled do not occur.
In addition, since the hanger is fixed between the side of the shelf member and the presser, the hanger is less likely to be damaged, and the position of the shelf relative to the hanger can be easily shifted by simply loosening the presser. Can be changed.
