Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is a vertically arranged endless chain multilayer suspension system used in multi-level warehouses, etc., in which each endless chain is driven separately, especially for the purpose of rapid removal of small items. The present invention relates to a multilayer suspension system that is economical, noiseless, capable of high-speed operation, and convenient for maintenance.

A typical example of a multi-layer suspension system using a vertically arranged endless chain is a multi-story parking facility, in which case there are two cages for placing bicycles.
It is well known to be suspended in a cyclically driven endless chain.

In addition, in the case of a multi-story parking facility where a relatively small number of bicycles are parked, it is uneconomical to use two endless chains, so it is common to suspend the cage by overhanging it on one side of the single endless chain. be. However, this method makes it unstable to maintain the posture of the cage, so conventionally the first
As shown in the figures and FIG. 2, a large number of guide rollers 20, 21, etc. are attached to the holding arm 19 of the cage 18 and the cage 18 itself, and these guide rollers 20, 21 are attached to high-precision guide rails 22, 23, etc. A method is used to maintain stability by guiding the vehicle.

However, with this method, the cost of the equipment is high, and since it has a large number of rollers, it generates noise and is disadvantageous in terms of maintenance.Furthermore, when removing slack from a worn chain, the guide rail at the folded part must be If there is no suitable means for adapting this and, for example, a means of inserting guide pieces 24, 25 as shown in FIGS. 3 and 4 is adopted, the work will be complicated and a large number of This is uneconomical since it is necessary to prepare a guide piece.

The object of the present invention is to provide a multi-layer suspension system that can advantageously solve the above-mentioned problems. , 2 are arranged at intervals in the longitudinal direction of an endless chain 4 extending in the vertical direction, and the open base end of each cage holding arm 3 is connected to the endless chain 4. The upper part of a cage 6 and a posture holding member 7 are fixed to a horizontal shaft 5 which is rotatably attached to the tip of the cage holding arm 3, and the cage 6 has a horizontal shaft 5 which is rotatably attached to the distal end of the cage holding arm 3. A plurality of guide shoes 8 and 9 for the lifting section are attached, and the guide shoes 8 and 9 are fitted into the guide member 10 for the lifting section parallel to the straight part of the endless chain 4, and A base end of a support arm 12 is fixed to the side around the chain wheel 11, and a horizontal shaft 13 rotatably attached to the tip of the support arm 12 is engaged with the posture holding member 7. The posture regulating member 14 and the rotating secondary chain wheel 15 are fixed, and the position is maintained between the fixed secondary chain wheel 16, which is arranged on the same center line as the main chain wheel 11 and fixed to the fixed part, and the rotating secondary chain wheel 15. This multi-layer suspension device is characterized in that a regulating endless chain 17 is wound around it.

Next, the present invention will be explained in detail using illustrated examples.

5 to 16 show an embodiment of the present invention, in which two links 1 and 2 are arranged in a V-shape to constitute a cage holding arm 3. A single lifting endless chain 4 extending vertically in a vertical plane is arranged at regular intervals in the longitudinal direction, and the base end of the cage holding arm 3, that is, the open end of each link 1, 2 is connected to the endless chain. Pin 20,2 for 4
6, and the upper and lower parts of the endless chain 4 are wound around the main chain wheel 11,
One main chain wheel is rotated by a drive device. At the distal end of the cage holding arm 3, one link 1 is pivotally connected to the other link 2 by a pin 27, and a horizontal shaft 5 is rotatably fitted. For example, the upper part of the cage 6 for placing an object to be stored such as a bicycle is fixed,
Further, a horizontal posture holding member 7 that functions only in the upper and lower folded portions is fixed to the other end of the horizontal shaft 5.

A support rod 28 is fixed to the cage 6, which extends parallel to the straight portion of the endless chain 4 when the cage is at an intermediate height, and guide shoes 8 and 9 for the lifting section are fixed to both ends of the support rod 28. and the guide shoes 8 and 9 are linear guide members 1 for lifting/lowering parts made of a pair of angle members arranged parallel to the straight part of the endless chain 4.
0, and the guide member 10 is fixed to a building or other fixed part.

As can be seen from FIG. 16, the vertical load at the tip of the cage holding arm 3 is supported by the chain tension component. Also, as shown in Figure 13,
The reaction force X+X', Y+Y' generated in the x and y directions, and the moment reaction force Mx=Y-Y'/2h and My=X-X'/2h, which are composed of the upper and lower shoe reaction forces, are applied to the cage 6. The posture is maintained. Regarding the Z-axis direction, of course, the tip load W of the cage holding arm 3
However, the moment load around the Z axis
Since Mz is small, it is supported by the moment reaction force made up of the chain tension component U and the shoe reaction force V through the rigidity of the rotating engagement part of the horizontal shaft 5 supporting the cage 6 and the cage holding arm 3. .

9 to 12 show the posture regulating devices for the upper and lower folded parts, and FIGS. 14 and 15 show the posture regulating devices for the upper and lower folded parts, taking the lower side as an example. In the upper and lower turning parts, there are no arcuate guide members for guiding the shoe, and instead, the posture of the cage at the turning parts is maintained by a unique posture regulating device attached to the main chain wheel. It shows the case.

To explain the posture regulating device in the upper and lower folded parts, an appropriate number of support arms 12 that protrude to the vicinity of the tip of the cage holding arm 3 are arranged and fixed at equal intervals on the circumferential surface of one side of the main chain wheel 11. A posture regulating member main body 14D and a rotating secondary chain wheel 15 are fixed to a horizontal shaft 13 rotatably attached to the tip of each support arm 12, and a fixed member disposed on the same center line as the main chain wheel 11. The auxiliary chain wheel 16 is fixed to a fixed part such as a frame so as not to rotate, and the auxiliary chain wheel 3 is located at a standby position on the side of the main chain wheel 11.
1 is rotatably attached to the fixed secondary chain wheel 16.
An endless chain 17 for regulating posture is wound around each of the rotating secondary chain wheels 15 and the auxiliary chain wheels 31.

The auxiliary chain wheel 31 is attached to the main chain wheel 11 so as to be movable in the chain tensioning direction, and a tensioning spring is engaged with the support fitting of the auxiliary chain wheel 31, so that the auxiliary chain wheel 31 functions as a chain tensioning wheel. It may also serve as

A pair of bifurcated forks 29 projecting downward at both ends of the attitude regulating member main body 14D,
30 is integrally provided and a vertical support shaft 32 fixed to the holding member 14E is slidably fitted to the posture regulating member main body 14D, and between the holding member 14E and the posture regulating member main body 14D, the vertical support shaft 32 is fixed to the holding member 14E. Support shaft 3
A push-down spring 33 is fitted to the main body 14D of the posture regulating member 2, and the posture regulating member 14 is constituted by a posture regulating member main body 14D with a fork and a holding member 14E attached to the main body 14D so as to be movable up and down.

In the posture regulating device configured in this manner, the posture regulating member 14 and the like maintain a constant posture even when the main chain wheel 11 rotates. Therefore, the posture regulating member 14 is arranged so as to be close to the posture holding member 7 attached to the cage 6 so that the posture regulating member 14 can regulate the instability of the cage posture. If it's related, Cage 6
The posture of the cage 6 can be maintained constant while the guide shoes 8 and 9 move in an arc away from the guide member 10.

Note that the forks 2 at both ends of the pressing member 14E
9 and 30 to hold the posture holding member 7 on the cage side, the Y direction reaction force and the moment reaction force around the You can make everything happen.

FIG. 15 shows the fork-equipped attitude regulating member 14 in sequence as the main chain wheel 11 rotates at the folded part.
The figure shows the process in which the object catches up with the cage-side posture holding member 7, docks, and then separates again. That is, in FIG. 15, if the rotational angular velocity of the main chain wheel 11 is ω, the moving speed of the posture holding member 7A on the cage side during descent is γω, and the movement speed of the posture regulating member 14A on the main chain wheel 11 side is γω. Tangent line speed Rω
>γω, so as the main chain wheel 11 rotates,
The posture regulating member 14A catches up with the posture holding member 7A, and the fork 2 is rotated approximately 90 degrees clockwise from the top position.
9 and 30 come to sandwich the posture holding member 7A, and finally the two are completely integrated as shown by 14B and 7B. 14C and 7C also show both in the same state.

Thereafter, the posture holding member 7C is moved to the posture regulating member 14.
It begins to lag behind C, and eventually the two are completely separated and occupy the relative positions shown by 7D and 14A. These processes are performed one after another in succession, and the posture regulating device of the present invention functions smoothly.

The above was explained using the lower folded part as an example.
The posture of the cage 6 can also be maintained constant in the upper folded portion by the same posture regulating device as in the case of the lower folded portion. Note that slack removal of the chain by moving the main chain wheel 11 at the folded portion can also be easily carried out since there is no arcuate guide.

FIG. 13 shows the generation of posture-maintaining reaction force against a cage at an intermediate height, and the main reaction force is generated by the guide shoes 8 and 9 attached to the cage 6 and the guide member 10, as shown by the solid line. The secondary reaction force is generated as a part of the main reaction force and a component of the chain tension, as shown by the dotted line.

Since this invention is configured as described above,
Even when individual driving is performed using a single endless chain 4, there is no need to use a large number of rollers and precise guide rails as in the past, and arc-shaped guides are also provided at the upper and lower folded parts to easily move the cage. There is no need to maintain the cage posture, and the intermediate cage posture holding section that occupies most of the travel can be constructed with extremely simple guide shoes 8, 9 and guide member 10, and therefore the multi-layer suspension system can be made at low cost. It can be manufactured by using a simple method, does not generate noise, and therefore can be operated at high speed.Also, the posture of the folded part can be maintained reliably by a simple means, and it is also easy to maintain. , the labor required when using a large number of rollers can be saved, and the slack in the chain can be taken up freely.
