[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the field of mechanical parking devices, and more particularly to a parking device for transferring and transferring automobiles using a slat conveyor for quietly operating a slat conveyor. Regarding the configuration.

[0002]

2. Description of the Related Art A mechanical parking device is a device for storing a car by utilizing a space three-dimensionally and at a high density, and various devices have already been proposed and implemented. Has contributed. Cars are delivered and transferred using a slat conveyor as a kind of such a parking device,
There are those that carry in and out and store the car. That is,
Equipped with a slat conveyor in each of a plurality of parking spaces for storing cars, on the other hand, as a conveyor for transporting cars, for example, using an elevator cage, or a traverser, etc. Then, the vehicle is transported by the transporter to the position closest to the required parking space, and then the slat conveyors of both the transporter and the parking space are operated in conjunction with each other to deliver and receive the vehicle, and vice versa. It is intended to leave the warehouse. Alternatively, an entrance / exit slat conveyor is further added, and the vehicle is delivered and transferred between the entrance / exit slat conveyor and the slat conveyor of the carrier.

[0003] Unlike the method using a pallet or a tray for placing an automobile, such a slat conveyor transfer / delivery type parking device has no dead time for removing the tray from the parking space and returning it. Therefore, it has a remarkable characteristic that the entrance / exit processing capacity is high.

FIG. 7 is a side view showing a portion of one sprocket wheel 86 of a conventional conveyor 80. As shown in FIG. Chain 81
Are linked by pins 85, 85,. A slat member 83, 8 having a U-shaped cross section as shown between the chain links 82, 82,.
Attach 3, ... The slat members 83, 83, ...
Are treads 84, 8 for supporting the wheels of the vehicle.
4, ... The sprocket wheel 86 has a shaft 8
The key 7 is fitted with a key 88 so as to be prevented from rotating. The illustrated sprocket wheel 86 is formed with six teeth 86 a so as to mesh with the chain 81.

In such a slat conveyor,
A conveyor chain having a relatively large pitch is suitable for a chain used for a slat member which is determined to have rigidity enough to withstand the load of a vehicle wheel even when locally applied. On the other hand, the structure of the slat conveyor is desirably as small as possible from the viewpoint of the occupied space and from the economical point of view. Therefore, it is desirable to use a sprocket wheel having as small a number of teeth or a diameter as possible.

[0006]

However, in the case of such a chain having a small number of teeth and a relatively large pitch, the pulsation when the chain mechanically circulates through the sprocket wheel becomes large, and therefore, the meshing occurs. Occasionally, it is accompanied by impact, causing noise.

[0007] Parking devices are mainly provided in cities, and due to recent interest in environmental issues,
Such noise is avoided, and it is particularly desired to develop a parking device that generates less noise.

The present invention has been made in response to such a trend, and an object of the present invention is to provide a slat conveyor transfer / transfer type parking device that is quiet in rotation and generates little noise.

[0009]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention relates to a construction of a slat conveyor transfer / transfer type parking device which is quiet and operates with low noise. Interlocking operation with the conveyor,
Between these conveyors, in a mechanical parking device that transfers vehicles and stores the vehicles in a parking space by transferring the vehicles, each of the above-mentioned conveyors circulates an endless chain between sprocket vehicles at both ends. The chain is a slat conveyor that supports and moves an automobile with a plurality of slat members as treads of automobile wheels, and in at least a part of the conveyor,
A buffer ring fitted coaxially to a shaft fitted with the sprocket wheel, and a slat member having a back surface that comes into contact with the buffer ring are used, and the slat member is brought into contact with the buffer ring. This is configured as a slat conveyor transfer delivery type parking device that circulates a sprocket vehicle.

[0010]

The present invention relates to a mechanical parking device for interlocking operation of a conveyor and a conveyor for transferring vehicles between the conveyors and transferring the vehicles and storing the vehicles in a parking space. Although there is a slide type or a traverser type, these are both at a fixed position and between a conveyor on a movable transfer machine, at least once, at least one delivery transfer is performed, Cars are entered or exited.

These conveyors are provided with slat members via attachments to a chain circulating between sprocket vehicles at both ends, and the slat members are treads to support automobile wheels. Further, in the present invention, a cushion ring made of an elastic material is fitted on the shaft on which the sprocket wheel is fitted, and a back surface which comes into contact with the buffer ring is formed on the slat member, thereby circulating the sprocket wheel. In such a case, the back surface of the slat member abuts on the buffer ring to suppress vibration of the chain, reduce the impact when the roller of the chain meshes with the sprocket wheel, and reduce noise.

The vehicle is delivered and transferred to the parking conveyor 40A (40), and is stored by being supported by the parking conveyor 40A (40). As a result, the cage 20 can move to the next entry or exit operation. In addition, the retrieval operation can be performed in a reverse procedure.

[0024] In such a whole loading and unloading operation,
As described above, when the loading / unloading conveyor 50 and the transporting conveyor 30 are operated, the sprocket wheels 52, 52 or the sprocket wheels 32, 32 of the loading / unloading conveyor 50, the transporting conveyor 30 are fitted on both ends of the shaft 53 or the shaft 33.
Buffer rings 56, 56 or buffer rings 36, 36 made of an elastic material such as rubber, which are fitted on the same concentricity, and slat members 55, 55, orbiting the sprocket wheels 52, 52 or the sprocket wheels 32, 32. .. Or the slat members 35, 35,... Abut on each other, so that the impact due to the pulsation is reduced, and the noise at the time of meshing is reduced.

The loading / unloading conveyor 50 is located at a position opened from the loading / unloading port 9 to the outside, and when the conveyor 30 is also at the loading / unloading level 8, it is inside the door 11 and is sound-insulated. , Since the vehicle is driven relatively close to the entrance 9, the noise during operation is reduced.
The quiet operation of the parking device 1 with less noise leakage to the outside is enabled.

[0026]

[Effects of the Invention] A parking device that arranges a slat-type conveyor and a conveyor in series, transfers and transfers a car, and performs a car entry / exit operation is an elevator system, an elevator slide system, a traverser system, or another type of parking system. It is applicable to the apparatus, and has a great advantage that the time required for loading and unloading can be shortened as compared with a system in which a car is transported using a tray, a pallet or the like. However, when the chain meshes with a sprocket wheel having a relatively small number of teeth, pulsation occurs in the chain, thereby generating noise, and there has been a problem recently due to increased environmental awareness.

According to the present invention, in a slat conveyor used for such a type of parking device, a buffer ring made of an elastic material having a diameter such that the slat member comes into contact with a slat member is fitted to a sprocket wheel shaft. When the member circulates through the sprocket wheel, the back surface of the slat member abuts on the buffer ring to reduce the shock at the time of meshing due to the pulsation of the chain, so that quiet operation with little noise leakage to the outside can be performed. It is possible to provide a parking device.
