Detailed Description of the Invention

[0001]

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

[0002]

2. Description of the Related Art In a conventional turn pallet type vertical circulation type parking device, as shown in a side view and a front view of FIG. 7, a pair of front and rear endless chains 2 and 2 are mounted between an upper sprocket 1a and a lower sprocket 1b. The cage 5 including the front and rear suspension frames 5b, 5b and 5c is suspended from the front and rear endless chains 2 and 2 at equal intervals via a plurality of intermediate shafts 5a. In addition, a lifting / rotating member 6 protruding in a pit recessed in the floor directly below the lower sprocket 1b and a wedge-shaped turn plate 3 having a central portion fixed to the upper end thereof.
A turn table (FIGS. 8 to 9) is provided. In such a device, at the time of warehousing, the turn plate 3 is slightly raised through the empty space of the lower frame 5c, the vehicle a is loaded into the pallet 5d at a position where the pallet 5d is slightly lifted from the lower frame 5c, and then the turn table 3 is mounted. Turn 180 ° and lower the pallet 5d to the original position.

In this type of parking apparatus, the garage is loaded on the pallet 5d as shown in the side view of FIG. 8 and the sectional view of FIG. 9IX-IX, and at this time, as shown in the sectional view of XX-X of FIG. The lower surface of 5d is in contact with the upper surface of the lower frame 5e. 5
c'is a longitudinal member of the lower frame 5c. When the pallet 5d is lifted by the turn table 3, the side view of FIG.
2 XII-XII As shown in the sectional view, there is a slight gap between the upper surface 5e of the lower frame and the pallet 5d. FIG. 13 shows the cage in the straight part of the chain 2.

[0004]

In this type of turn pallet type vertical circulation parking apparatus, since the pallet attached to each cage can be turned, not only from the longitudinal direction of the cage, but also if necessary. Although the vehicle can be loaded and unloaded quickly and easily from the lateral and diagonal directions, it has the following problems. (1) Since each cage is formed to have a height corresponding to the height of the pallet in order to secure the height for lifting the pallet in each cage, an increase in the total height of the entire apparatus including a large number of cages is reduced. As a result, the number of cages, that is, the number of accommodations, decreases due to height restrictions from the location conditions. (2) Compared to the standard type cage without a turn pallet, the cages with built-in turn pallets have different dimensions of each member and the hanging intervals on the endless chain are different, so a special member is required and the hanging position must be changed. Cost is high because it is required.

The present invention has been proposed in view of the above circumstances, and is an economical turn pallet type vertical circulation system capable of loading and unloading in a narrow space, increasing the number of cages, and reducing the cost. An object is to provide a parking system.

[0006]

To this end, the present invention provides
An endless chain is looped around an upper sprocket and a lower sprocket, which are arranged side by side at appropriate intervals in the vertical direction, and placed on a pair of front and rear suspension frames and a lower frame and a lower frame on the endless chain, respectively. A pallet gauge is suspended at equal intervals, and a turntable with a support frame for lifting and rotating the pallet is installed on the floor just below the lower sprocket.The cage is brought to the lowest position as the endless chain moves. When struck, the supporting frame that rises through the void in the lower frame of the cage raises the pallet for the vehicle mounted on the lower frame slightly and then turns 180 ° to turn the vehicle. In the pallet type vertical circulation parking device, the level at which the pallet is placed on the lower frame is Lower than the upper surface of the lower frame is level, characterized in that so as to perform the entry and leaving the car through the upper surface of the lower frame when lifting the pallet support frame.

[0007]

According to this structure, by lowering the position of the pallet during circulation operation from the upper surface of the lower frame, the height at which the pallet is lifted and turned can be set to the upper surface of the lower frame. The cost can be reduced because each member of the cage can be shared with the standard type cage without increasing the cage suspension interval.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to the drawings, one embodiment of the present invention is shown in FIG.
II-II horizontal sectional view and its AA, BB sectional view, FIG. 3 is a horizontal sectional view taken along line III-III of FIG. 1, and FIG. 4 is a side view showing a state in which the pallet is lifted in FIG. Is V in FIG.
FIG. 6 is a lateral cross-sectional view taken along line -V, and FIG. 6 is a side view showing the cage in the straight portion of the endless chain.

The cage structure of the present invention differs from the conventional one in that the conventional cage has the pallet at the same level as the upper surface of the lower frame of the cage during the circulation operation, while the cage of the present invention does not. It is located at a level slightly lower than the upper surface of the lower frame of the cage, and when turning by the turn plate, the pallet is lifted to the same level as the lower frame of the cage to turn the pallet. That is, when the cage is at the lowest position, the pallet 5d is at a position slightly lower than the upper surface 5e of the lower frame, as shown in FIGS. Here, as shown in FIGS.
Due to the turn plate 3, the floor surface of the pallet 5d is the upper surface 5e of the lower frame.
The pallet 5d can be lifted to a position at which the pallet 5d is at the same level as the pallet 5d.
You can turn d. At that time, as shown in the BB cross section on the inlet side and the AA cross section in the central portion, the lower frame 5c ′ suspended by the suspension frame 5b is lowered downward by the eccentric amount 5f, and the pallet 5d and the turn plate 3 are arranged. It is possible to turn smoothly and safely when turning.

The warehousing is carried out as follows. That is,
As shown in FIGS. 4 to 5, after performing the circulation operation and bringing the empty cage 5 to the lowest position, the turn plate 3 is lifted,
The vehicle is loaded with the pallet 5d being lifted until the floor surface of the pallet 5d is at the same level as the upper surface 5e of the lower frame.
When changing the direction of the vehicle, after this, the pallet 5d and the warehousing vehicle a are turned together with the turn plate 3, the turn plate 3 is lowered, and the pallet 5d is placed on the lower frame 5c ″ to complete the warehousing.

Delivery is carried out in the following manner. That is,
The pallet 5 is circulated and brought to the lowest position, the cage 5 in which the delivery vehicle is stored is raised to the lowest position, the turn plate 3 is raised, and the floor of the pallet 5d is at the same level as the upper surface 5e of the lower frame.
Lift d. When turning the car, turn the pallet 5d and the delivery car together with the turn plate 3 after this,
After leaving the car, the turntable 3 is lowered, the pallet 5d is placed on the lower frame 5c ", and the leaving is completed.

[0012]

According to such a structure, the vehicle can be turned while the floor surface of the pallet and the upper surface of the lower frame are at the same level. Therefore, unlike the conventional example, it is not necessary to increase the cage height and the cage suspension interval in order to change the direction of the vehicle, and each member of the cage can be shared with the standard type cage.
By the way, since the standard type and the turn pallet built-in type generally have different dimensions, conventionally, there are almost no common parts, but according to the present invention, the cage pitch of the turn pallet built-in type and that of the standard type are the same, Main parts such as the cage suspension frame and chain are common parts, which is extremely beneficial for cost reduction.

In short, according to the present invention, the endless chain is looped around the upper sprocket and the lower sprocket, which are juxtaposed at appropriate intervals in the vertical direction,
A pair of front and rear suspension frames, a lower frame, and a gauge composed of a pallet placed on the lower frame are suspended at equal intervals on the endless chain, and a support for lifting and rotating the pallet on the floor immediately below the lower sprocket is supported. A turntable having a frame is provided, and when the cage is brought to the lowest position due to the movement of the endless chain, it is placed on the lower frame by a support frame that goes up through the void in the lower frame of the cage. In the pallet type vertical circulation type parking device in which the car is turned around by slightly lifting the car pallet and then turning it by 180 °, the level at which the pallet is placed on the lower frame is the car entry level. It is lower than the upper surface of the lower frame, and when the pallet is lifted by the support frame, cars can be loaded and unloaded through the upper surface of the lower frame. As a result, an economical turn pallet type vertical circulation type parking device that enables storage and withdrawal in a narrow space, increases the number of cages, and reduces costs is provided. It is something.
