Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vertical circulation type mechanical parking device.

[0002]

2. Description of the Related Art A vertical circulation type mechanical parking device called tower parking is known as one of the facilities for efficiently parking a vehicle on a limited site.

The vertical circulation type mechanical parking apparatus has a drive sprocket 2 at an upper position in the building 1 and a driven sprocket 3 at a lower position, as shown in FIG.
And the upper and lower sprockets 2, respectively.
An endless chain 4 is hung between 3 and a cage 6 provided with a pallet for mounting a vehicle 5 is attached at a required interval position of the chain 4, and a drive sprocket 2 is rotated by driving a motor 7. By moving the chain 4 so that the cage 6 can be circulated and moved, the vehicle 5 loaded from the loading / unloading port 8 is placed in the cage 6 located at the bottom, and the cage 6 is moved to an arbitrary position. It is designed to be transported to and parked.

The chain 4 used in the above mechanical parking apparatus is, as shown in FIGS. 4A and 4B, composed of a pair of narrowly spaced link plates 9a and a slightly widened link plate 9b. Pin 10 by overlapping the ends one by one
Is connected rotatably with, for example, a V-shaped attachment 11 for suspending the cage 6 is attached to the pins 10 at both ends of every other link plate 9b, and at the same time, A guide roller 12 is rotatably attached to one end, and as shown in FIG. 5, inner and outer chain guide rails 13, which are provided in parallel in the vertical direction to guide the vertical moving portion of the vertical chain 4, 14
By positioning the guide roller 12 between them and moving the chain 4 along the chain guide rails 13 and 14, the chain 4 is prevented from rolling when the chain 4 is moved up and down, and the cage 6 is stabilized. It is designed to be

[0005]

However, in the case of the above-described vertical circulation type mechanical parking apparatus, the chain 4 is provided in the vertical portion.
Since the guide roller 12 attached to the above is sandwiched between the inner and outer chain guide rails 13 and 14, the chain 4 is stable even if a biased load of the cage 6 acts on the chain 4 via the attachment 11. Although it can move, when the driven sprocket 3 is engaged with the driven sprocket 3 and is pivotally moved, the position regulation by the outer chain guide rails 13 and 14 of the guide roller 12 is released, so that the chain 4 is driven. There is a problem in that a noise occurs when the sprocket 3 is hit by the movement during the movement along the. That is, the load of the cage 6 acts on each pin 10 of the link plate 9b on which the cage 6 is suspended via the V-shaped attachment 11 via the V-shaped attachment 11, but at the time of turning movement, it is coaxial. Since the position of the upper guide roller 12 is not regulated, the rotational displacement of the driven sprocket 3 causes a force to be pressed against the driven sprocket 3 as shown by an arrow A in FIG. Sprocket 3
When the chain 4 turns, the pin 10 separates from or comes into contact with the tooth groove of the driven sprocket 3, and the contact noise at this time is generated as noise. There's a problem.

Therefore, according to the present invention, the pin of the link plate to which the cage is attached does not come into contact with or separate from the driven sprocket when the driven sprocket rotates, so that the pin contacts the driven sprocket. It is intended to prevent the generation of noise when touching.

[0007]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention sequentially connects a plurality of link plates with pins between a drive sprocket and a driven sprocket arranged vertically in a building. An endless chain consisting of the above is hung around, the vehicle mounting cage is attached to the pin of the link plate at the required interval position of the chain via an attachment, and a guide roller is provided at one end of the pin and arranged in parallel in the vertical direction. In a mechanical parking device in which the guide roller is guided between the inner and outer chain guide rails to move the chain in a vertical portion, an arc along the driven sprocket is located below the driven sprocket. A lower guide rail having a trajectory guide surface is provided, and the lower guide rail is attached to the chain guide outside the vertical portion. Coupled to the lower end of the rail, the guide surface of the outer side of the chain guide rails is continuously on the guide surface of the lower guide rail and configured comprising.

[0008]

When the chain is engaged with the driven sprocket and is pivotally moved as the driven sprocket rotates, the guide roller is smoothly transferred from the vertical chain guide rail to the lower guide rail. Since the guide surface of the lower guide rail has an arcuate shape corresponding to the driven sprocket, the guide roller is constrained at a certain distance from the center of rotation of the driven sprocket to roll. Therefore, even if the load of the cage acts on the pin to which the guide roller is attached, the meshing state of the pin with respect to the driven sprocket is maintained, so that the generation of noise is prevented.
