Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a vertical circulation parking system in which two cars are stored in one tray in one direction, one in which the cars come in and one out. '□ Conventionally, a vertical circulation parking system has already been proposed in which the trays are extended in the longitudinal direction and the trays are arranged in a line or in series in the same direction as the direction of vehicle traffic in order to store two cars. However, in such a parking device, the vertical circulation drive device for the tray must be installed independently in the back side parking device and the entrance side parking device.
It is necessary to move the car on the entrance side out of the front parking device in advance, or to provide two entrances and exits, which increases the parking area, reduces land use efficiency, and becomes uneconomical. - It takes a long time to take out the warehouse due to the rotation operation, resulting in poor workability and problems in terms of safety.

On the other hand, the present invention is a "vertical circulation type parking device that can solve the above-mentioned problem," and the applicant has developed a system in which sprocket wheels are installed on a pair of sprocket wheels that are already installed in the vertical direction on the image side. In a parking device of a type in which a plurality of car storage cages are suspended and supported on an endless chain via attachments, and each cage is driven to circulate vertically by rotating one side of the sprocket wheel using a suitable drive mechanism. , a horizontal slide tray for mounting on a car and an immovable cage member tray are superimposed on the upper surface of the cage member of each cage, and at the lowest position of the cage, the horizontal slide tray is raised via an elevating frame by a frame drive mechanism. Patent application Sho 5s-2, characterized in that the device is configured to be slid to either the left or right with respect to the direction of vehicle entry and exit using another drive mechanism.
No. 31423 (filed on December 9, 1982) is proposed.

However, in the vertical circulation parking device according to the original patent application, when two cars are stored in the cage, there is a lateral error between the drive device that slides the tray on the entrance side sideways and the stopping position of the cage after vertical circulation. There is a drawback that it is impossible to adjust the positioning of the horizontal slide to get out.

On the other hand, according to the present invention, a centering mechanism consisting of a motor and a rotating arm is attached to the elevating frame on which the horizontal slide tray is placed, so that the horizontal slide mechanism is made to follow the stopping error of the cage. This makes it possible to correct errors when landing on the cage, prevent troubles from occurring, and enable smooth and safe parking operation.

Next, the present invention will be explained in more detail with reference to an embodiment shown in FIGS. 1 to 5.

Several dozen storage cages 7 are suspended at equal intervals from two endless bands, for example, endless link chains 4 and 5, which are stretched between rocket wheels 2 and 3 through attachments 6, and placed on a machine base 8. The upper sprocket wheel is rotated by a vertical circulation drive device 9 consisting of an electric motor, a brake, a speed reducer, a machine stand, etc. to be arranged, so that each cage is circularly driven in the vertical direction. In this case, as shown in FIG. 3, the storage cage mainly consists of cage members 10 assembled in a cross-shaped structure, gate-shaped hangers 11 installed at both longitudinal ends of one cage member, and the upper parts of these hangers. It is composed of a rod 12 connecting the cage members, an immovable cage member tray 13 and a horizontal slide tray 14 which are superimposed on the cage member and are to be pushed. Furthermore, the cage member tray 13 and the horizontal slide tray 14 are arranged adjacent to each other in the vehicle entry direction, that is, in the longitudinal direction of the storage cage, and the cage member tray is located at the back 1° above the cage member of the storage cage. The horizontal slide tray is integrally formed on the side and is provided on the entrance side of the cage member so that it can slide in either the left or right direction (in FIG. 3, the left direction in FIG. 3) with respect to the direction of vehicle entry and exit.

Furthermore, as shown in FIGS. 4 and 5, a horizontal slide tray 14 is placed on the bottom surface 17 of the pit 16 formed on the floor surface 15 that serves as the vehicle entry/exit surface, and is raised (or lowered). A drive mechanism 19 for the elevating frame 18 is installed,
The pedestal drive mechanism is.

A power cylinder unit 20 that is mainly arranged in parallel with the direction of vehicle entry and crank levers 21 and 21 at both ends.
The power cylinder unit has a built-in pole screw that is operated by a drive motor 24 pivoted to a bracket 23 installed on the bottom surface 17 of the pit 16. It even consists of a cylinder 25, in which the rod 2 of the cylinder

7, and the crankshafts 22, 227
Both ends of the crank lever 21.21 are pivoted to support brackets 28.28' installed on the pit bottom 17, and
Push-up rollers 29, 29' for clamping the elevating frame 18 are pivotally attached to both ends of the /, and crank levers 21, 21/ on one side are connected by a connecting rod 30.

Also, place the horizontal slide tray 14 and raise it □
After the tray is closed, a plurality of drive rows 231 and sliding driven rollers 32 are arranged in parallel on the side edge of the elevating frame in the sliding direction for sliding the tray to either the left or right. The drive roller 31 is drive-coupled to a slide motor 33 installed at the lower end of the lifting platform by an endless band 34, and is also drive-coupled to the central drive roller 31 via a free roller 35 by an endless band 36. A U-shaped protrusion 3 is formed on the elevating pedestal so as not to hit the cage member 10 of the cager when the pedestal is raised, and the free roller is installed on the protrusion.

Reference numeral 38 denotes an auxiliary pedestal fixed to the floor surface 15 on the slide side at the same level as the lifting pedestal during the day. A number of rollers 39 are arranged in parallel, and a chain guide 41 of the endless link chains 4 and 5 is a road floor affixed to the elevating frame 18, and a slide drive roller installed on the elevating frame 18 is provided. 31 and the driven roller 32 are preferably made to protrude slightly, for example, by 10 to 15 degrees, from the roadway floor.

In addition, as shown in FIGS. 4 and 5, there is also an elevating frame 18 on which the horizontal slide tray 14 is placed, and the bottom surface 1 of the bit 16.
7, there is a guide 42 mainly used for centering and lifting, and a rotating roller 43 that fits and slides on the guide 42.
A centering mechanism 46 is installed for causing the elevating frame to follow the cage landing position, which is composed of a rotating arm 44 on which the roller is attached and a motor 45 for operating the arm; in this case, the guide is connected to the elevating frame. 18, and a rotating roller 43 is attached to the tip thereof, and by the reciprocating swing of the rotating arm, the elevating pedestal is centered in the direction of the double arrow through the rotating roller and the guide, and is guided up and down. do.

Thus, in the device of the present invention having the above-mentioned configuration, when taking out (entering) a warehouse, as shown in FIG. If the cage is displaced to either the left or right when the cage is stopped, that is, when the cage is placed on the floor, the inside of the rib-shaped protrusion 3 that forms the elevating pedestal on the cage member 10 of the cage will move upward. As a result, the horizontal slide tray 14 cannot be properly placed on the elevating pedestal. Therefore, by moving forward, the cage landing position is appropriately detected by a sensor such as a phototube, and the motor 45 of the centering mechanism 46 is driven by a distance corresponding to the cage stop error to swing the swing arm 43 in the direction of the double arrow. Centering is performed by making it follow.

;,・Then, as shown in FIG. 5, it is stored in the cage 7.
If the car on the far side of the two cars at t is to be taken out of the garage, the car on the entrance side must be removed in advance. The elevating frame 18 on which the horizontal slide tray 14 on which the automobile is mounted, which was supported by clamp rollers 29, 29' pivotally mounted on the free ends of the

The drive roller 31 and driven roller 32 for sliding attached to this come into contact with the back surface of the horizontal slide tray 14, and subsequently move the elevating pedestal by a certain amount, for example, 20 to 30#E.
After stopping the drive motor or cylinder in the lifted state, the elevating pedestal 18 supported by the slide drive motor and the driven roller 32 slides in the direction of the arrow by the rotational frictional force of the roller, and therefore the horizontal slide tray 14 In FIG. 4, the car is removed to the left side of the entrance side with a portion of the car straddling the auxiliary frame 38, and is removed to the outside of the exit route.

Next, the car on the back side is taken out from the cage member tray 13 via the road bed 41 of the elevating frame 18,
When this unloading is completed, the power cylinder unit 20 of the gantry drive mechanism 19 is operated in the opposite direction to when the gantry is raised, thereby moving the clamp levers 21, 22/in the counterclockwise direction, that is, from the solid line position to the dotted line position (see Fig. 5). ), the elevating frame 18 descends while being supported by the clamping rollers 29 and 29' at the tip of the lever and returns to its original position.

In addition, in the diagonal embodiment, the horizontal slide tray (lay 1
To slide 4, drive motor 33° endless band 3.4
．． ．． 36 and a drive roller 31, etc., but instead of this, any suitable drive mechanism such as a pusher or a traction drive mechanism may be used, and the sliding direction may also be reversed. Of course you can get it.

4. In the additional related original patent application, Japanese Patent Application No. 1982-23142J (filed on December 9, 1988), 1 is installed in the vertical direction on both sides.
A plurality of car storage cages are suspended and supported via attachments on endless chains stretched between each pair of sprocket wheels, and one side of the sprocket wheels is rotated by an appropriate drive mechanism, so that each of the cages is In this type of parking device, a horizontal slide tray for placing a car and an immovable cage member tray are superimposed on the upper surface of the cage member of each cage, and the horizontal slide tray is disposed at the lowest position of the cage. After the gantry drive mechanism 1 raises the two cars via the elevating gantry, another drive mechanism moves the two cars to the left and right with respect to the car entry/exit direction. When storing, the positioning of the horizontal slide cannot be kept constant because there is a left-right error in the drive device that slides the tray on the entrance side laterally and the stopping position of the cage after vertical circulation. By attaching a centering mechanism consisting of a guide, a rotating arm, and a motor to the elevating frame on which the horizontal slide tray is placed, the horizontal slide mechanism can compensate for errors when the cage is placed on the floor by causing the horizontal slide mechanism to follow the error in stopping the cage. It has been improved to do so.
