Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to an endless chain stretched on a pair of sprocket wheels installed vertically on both sides, and several motor vehicle storage trays are attached to the endless chains via attachments. The present invention relates to a parking apparatus of a type in which each tray is vertically circulated and driven by suspending and supporting and rotating the upper sprocket wheel by an appropriate drive mechanism. The present invention relates to a vertical circulation parking device in which a turntable is not incorporated in a tray to be placed, and a car that has entered in the forward direction is allowed to exit in the forward direction.

(Prior Art) Japanese Patent Laid-Open No. Sho 56-56 has been proposed as a vertical circulation type parking device as described above.
Those disclosed in Japanese Patent Publication Nos. -20278, 64-7190 and 64-11791 are proposed.

(Problems to be Solved by the Invention) In the conventional vertical circulation type parking device, since the pallet portion of the tray needs to be separated from the hanger frame and rotated, the height of the entire tray must be increased. Since it is not possible to reduce the tray height,
A mechanical parking device has been proposed in which a pallet and a hanger frame can be attached and detached as disclosed in Japanese Patent No. 45, but this has an eccentricity of a tray long axis for pivotally mounting the hanger frame. That is, both ends of the connecting shaft to the tray long shaft of the hanger frame are formed in a crank shape, so that the hanger portion of the connecting shaft to the tray long shaft is pivotally supported by the upper end of the hanger frame to rotate, and Since the lower part of the hanger frame is detached and becomes a free support, there is a drawback that the rigidity of the entire tray is lost.
Also, regarding the tray length, since it has to be performed inside the hanger frame when the tray is rotated, the tray length must be increased, which inevitably increases the cost.

An object of the present invention is to provide a vertical circulation type parking device capable of solving the above-mentioned problems by rotating the entire tray without incorporating a turntable in the tray on which an automobile is mounted. .

(Means for Solving the Problem) Therefore, according to the present invention, the tray suspension shaft is fitted into the fork-shaped recess formed at the free end of each attachment, and the tray suspension shaft is disengaged during the moving circulation. To prevent the tray from slipping off along the outside of the link chain, install an arc guide rail that fits the guide roller of the tray across the beginning and end of the downward trajectory of the tray. A tray elevating drive mechanism consisting of a tray elevating machine and a tray supporting frame is provided in the notch formed at the tray lowermost position of the stopper guide, and both ends of the tray suspension shaft are supported on the tray supporting frame, and the tray elevating drive is performed. By operating the mechanism, the entire tray is lowered to form a free support, and the tray rotating mechanism rotates the entire tray.

(Embodiment) In FIG. 1 and FIG. 2, two pairs of upper and lower sprocket wheels facing each other installed on the inlet side and the back side.
Two endless link chains 3 stretched over 1 and 2 are mounted on an in-vehicle tray 5 via an attachment 4
Are suspended and supported at equal intervals, and each tray can be vertically moved and circulated by rotating the upper sprocket wheel by an appropriate drive mechanism (not shown). The tray is a pallet. 6 and a gate-shaped hanger frame 7 standing upright at both longitudinal ends of the pallet
And a tray suspension shaft 8 connecting the upper parts of these hanger frames. At the free end of the attachment 4 attached to the link chain 3, there is formed a fork-shaped recess 9 into which the tray suspension shaft 8 is fitted, as shown in FIG. A guide 10 is provided along the outside of the link chain 3 so as not to come off from the attachment 4, and a U-shaped groove 12 formed on both ends 11 of the fork-shaped recess is fitted and slid. Which corresponds to the downward rotation trajectory of the tray 5,
Two arcuate guide rails 13 are installed at the start end and the end of the tray, and guide rollers 14 attached to both upper side surfaces of the hanger frame 7 are fitted on these guide rails 13 to rotate the guide rollers 14 below the tray. It prevents run-out during rotation.

Also, at the lowest position of the tray 5, the attachment 4 that has been fitted and slid with the tray removal prevention guide 10 until then.
A notch portion 15 is formed in the guide corresponding to the lower fixed position of the tray, and a tray elevating drive mechanism 19 including a tray elevating machine 16 and a tray elevating support frame 18 drivingly connected to the tray elevating machine 16 is provided. The support piece members 20 which are installed symmetrically in the notched portion so that they can be synchronously driven and which are attached to both ends of the tray suspension shaft 8 are carried by the tray lifting support frame,
The pallet 6 of the tray is a tray rotating mechanism which is lowered from the tray lowermost position and driven and rotated by a motor 21.
Placed on 22.

(Operation) In the vertical circulation type parking device as described above, when the tray 5 moves and circulates and reaches the lowest position as shown in FIG. The tray support frame 1 screwed to the screw rods 17 and 17 by operating the tray elevators 16 and 16 of the tray lifting and lowering drive mechanism 19 and 19
8, 18 descends, and the tray suspension shafts 8 to 5, which were carried by the tray support frame via the support piece members 20, 20 in the solid line position, descend to the position indicated by the chain double-dashed line (about 200 mm). ), The whole tray becomes a free support and is placed on the tray rotating mechanism 22, and in this state, if the motor 21 is driven after getting in the vehicle forward or when leaving the vehicle,
The tray rotating mechanism or the tray is rotated by 180 ° so that the vehicle can be loaded and unloaded forward.

Next, when the loading and unloading of the vehicle is completed, the tray lifts 16 and 16 of the tray lifting and lowering drive mechanisms 19 and 19 are operated in reverse to raise the tray support frames 18 and 18 and the tray suspension shaft 8 to the tray 5 The tray 5 reaches the lowest position of the moving circulation, and the guide rollers 14, 14 and the arc-shaped guide rails 13, 13 are picked up.
It is brought into the vertical circulation path by the co-action of and is placed in place.

(Effects of the Invention) From the above description, according to the present invention, the free end of the attachment attached to the link chain is formed as a fork-shaped recess, and the tray suspension shaft is provided along the outside of the link chain so as not to come off. Since a guide is provided and a tray elevating drive mechanism and a tray rotating mechanism are provided at the tray lowermost position, the conventional tray can be used as it is without processing, and the entire tray can be rotated as a free support. Therefore, the cost can be reduced without losing the rigidity, and since the vehicle can be put in and out by moving forward, the occurrence of accidents due to immature driving can be reduced and the parking efficiency can be improved. is there.
