Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement of a vertical circulation type parking device in which two cars are stored in one tray in the same direction as the entry and exit direction of the cars.

Conventionally, in order to store two cars by extending the length of the tray, a vertical circulation parking system has been proposed in which the trays are arranged in tandem or in series in the same direction as the car entry/exit direction. In such a parking device, the vertical circulation drive device for the tray must be installed independently in the rear parking device and the entrance parking device, so in order to take out the vehicle in the back, the vehicle in the entrance is parked in the front. It is necessary to either take the vehicle out of the device or provide two entrances and exits, which increases the area occupied by the parking lot and reduces land use efficiency, making it uneconomical.In addition, it takes a long time to exit the parking lot due to driving operations. There are problems in terms of workability and safety.

On the other hand, as a vertical circulation type parking device that can solve the above-mentioned problem, the applicant has developed a plurality of endless chains that are stretched through a pair of sprocket wheels that are already installed vertically on both sides, through attachments. In a parking device of the type in which each car storage cage is suspended and supported and each cage is vertically cyclically driven by rotating one side of the sprocket wheel by a suitable drive mechanism, the cage member of each storage cage is A horizontal slide tray and a fixed tray for mounting on a car are placed on top of each other on the top surface, and at the lowest position of the cage, the horizontal slide tray is raised via a lifting frame by a gantry drive mechanism, and then another drive mechanism is used to lift the lateral slide tray onto a car. A patent application made in 1983 that was configured to slide to either the left or right with respect to the loading/unloading direction.
No. 231423 (Unexamined Japanese Patent Publication No. 126469/1983) is proposed.

However, in the vertical circulation parking device according to the 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. Therefore, there is a drawback that the positioning of the lateral slide cannot be made constant.

On the other hand, in order to solve the above problem, in the present invention, a horizontal sliding tray and a fixed tray for mounting on a car are arranged adjacently and stacked on the top surface of the cage member of each storage cage from the back side in the longitudinal direction of the cage. death,

The vehicle is configured to move the vehicle in and out of the garage by raising the elevating frame and placing the horizontal slide tray thereon, and then operating the tray slide mechanism to move the horizontal slide tray. be.

Thus, according to the present invention, by attaching a centering mechanism consisting of a motor and a swivel arm to the elevating frame on which the horizontal slide tray is placed, the elevating frame is moved by the operation of the tray slide mechanism corresponding to the stopping error of the cage. This allows the car to follow the landing position of the car, thereby making it possible to correct errors when landing on the cage, thereby preventing the occurrence of troubles and making it possible to perform smooth and safe parking operations.

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

In FIGS. 1 and 2, two endless bands, for example, an endless link chain 4, are stretched between upper and lower sprocket wheels 2 and 3, which are arranged opposite to each other and are provided on the entrance side and back side of a building 1. , 5 to several storage cages 7 via attachments 6.
are suspended at equal intervals, and 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. arranged on a machine base 8. The cage is configured to be circularly driven in a vertical direction, and in this case, as shown in FIG. The planted gate-shaped hangers 11, the rods 12 that connect the upper parts of these hangers, the fixed tray 13 placed overlappingly on the back side on the cage member, and the horizontal sliding tray 14 on the front side.
It is composed of. Further, the fixed tray 13 and the horizontal slide tray 14 are arranged adjacent to each other from the back side in the vehicle entry/exit direction, that is, the longitudinal direction of the storage cage 7 , and the fixed tray is connected to the cage member 10 of the storage cage 7 . The horizontal slide tray is integrally formed on the back side of the top and is provided on the entrance side of the cage member so that it can slide in either the left or right direction (the left direction in FIG. 3) with respect to the direction of vehicle entry and exit. be.

Further, as shown in FIGS. 4 and 5, a horizontal slide tray 14 is placed on the bottom surface 17 of the pit 1 formed on the floor surface 15 that serves as the vehicle entrance/exit surface, and is raised (or lowered). A drive mechanism 19 for the elevating frame 18 is installed, and the frame drive mechanism mainly includes a power cylinder unit 20 arranged in parallel with the direction of vehicle entry, and a crankshaft 22 having crank levers 21, 21' at both ends. ,2
2', and the power cylinder unit consists of a cylinder 25 incorporating a ball screw operated by a drive motor 24 pivotally mounted on a bracket 23 installed on the bottom surface 17 of the pit 16. The rod 26 of the cylinder is drivingly connected to an actuating arm 27 attached to one crankshaft 22, and both ends of the crankshafts 22, 22' are connected to support brackets 28, 28, which are attached to the pit bottom 17. 28', and at the free ends of the crank levers 21, 21' are push-up rollers 29, 2 for clamping the lifting frame 18.
9', and one crank lever 21 is connected by a connecting rod 30.

Further, after the horizontal slide tray 14 is placed on the elevating pedestal 18 and raised by the operation of the pedestal drive mechanism 19, the tray slide mechanism 47 for moving the tray to either the left or right is as described below. It is configured.

That is, a plurality of driving rollers 31 and sliding driven rollers 32 are arranged in parallel on both sides of the sliding direction of the elevating pedestal 18, and in this case, the outer driving roller ₃₁₁ is placed at the lower end of the elevating pedestal. It is connected to the installed slide drive motor 33 by an endless belt, for example, an endless link chain 34, and is also connected via a free roller 35 to the central drive roller ₃₁₂ by an endless belt, for example, an endless link chain 36. A conical protrusion 37 is formed on the elevating pedestal so as not to hit the cage member 10 of the storage cage 7 when the pedestal is raised.
The free roller is installed in 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 18 when it is raised. roller 3
9 are arranged in parallel, 40 is a chain guide for endless link chains 4 and 5, and 41 is an elevating frame 1.
8, the sliding drive rollers 31 ₁ , 31 ₂ and the driven roller 32 installed on the elevating frame are slightly smaller than the road bed, for example.
It is preferable to protrude 10 to 15 mm.

Further, as shown in FIGS. 4 and 5, between the elevating frame 18 on which the horizontal slide tray 14 is placed and the bottom surface 17 of the pit 16, there is a guide 42 which mainly serves for centering and elevating. A centering mechanism 46 is installed for causing the elevating frame, which is composed of a rotating roller 43 that fits and slides, a rotating arm 44 to which the roller is mounted, and a motor 45 that operates the arm, to follow the cage landing position. In this case, the guide is the elevating frame 18.
The base of the rotating arm 44, which is fixed to the back surface of the pit and has a rotating roller 43 attached to its tip, is attached to the bottom surface 17 of the pit.
By the reciprocating swing of the swing arm, the elevating frame is centered and guided up and down in the direction of the double arrow via the swing roller and guide.

Thus, in the device of the present invention having the above configuration, when leaving (entering) the warehouse, as shown in FIG.
When the (empty cage) is circulated to the lowest position and stopped, that is, when the cage is placed on the floor, if the cage is displaced to the left or right, an elevating platform 18 is formed on the cage member 10 of the cage. Since the inside of the shaped protrusion 37 hits as the pedestal rises,
The horizontal slide tray 14 cannot be properly placed on the elevating frame. Therefore, beforehand,
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 cause the swing arm 43 to swing and follow in the direction of the double arrow. Perform 18 centering steps.

Next, as shown in FIG. 5, when the car on the back side of the two cars stored in the cage 7 is to be taken out, the car on the entrance side must be removed in advance. Until then, the clamp push-up rollers 29, 29' are pivotally connected to the free ends of the crank levers 21, 21' of the gantry drive mechanism 19.
The elevating pedestal 18 on which the horizontal slide tray 14 on which the automobile is carried is moved by driving the drive motor 24 forming the power cylinder unit 20 of the pedestal drive mechanism and pulling the cylinder rod 26. The crankshafts 22, 2 are
In order for the crank levers 21, 21' of 2' to swing in the direction of the hour hand, that is, from the two-dot chain line position to the solid line position in FIG. , a slide drive roller 31 and a driven roller 32 attached thereto.
comes into contact with the back surface of the horizontal slide tray 1, and then the drive motor or power cylinder unit is stopped with the elevating frame raised slightly, for example, by 20 to 30 mm, and then the slide drive motor 33 of the tray slide mechanism 47 is driven. If so, the driving roller 31 rotates via the endless bands 34 and 36, and therefore the elevating platform 18 supported by the driving roller 31 and the driven roller 32 moves in the direction of the arrow by the rotational frictional force of each roller. Therefore, the horizontal slide tray 14 is carried out in a state in which a portion thereof straddles the auxiliary frame 38 in the left-lateral direction on the entrance side in FIG. 4, so that the automobile is removed to the outside of the exit route.

Next, the car on the back side is taken out from the fixed tray 13 via the road bed 41 of the elevating pedestal 18, and once this leaving is completed, the trestle drive mechanism 1
By operating the power cylinder unit 20 of 9 in the opposite direction to when the gantry is raised, the crank lever 2
1 and 21' in the counterclockwise direction, that is, from the solid line position to the dotted line position (see FIG. 5), the elevating frame 18 is lowered while being supported by the clamping push-up rollers 29 and 29' at the tip of the lever. It will be restored to its former status.

In the embodiment described above, the tray slide mechanism 47 consisting of the slide drive motor 33, the endless bands 34, 36, the drive roller 31, etc. was used to move the horizontal slide tray 14, but instead of this, the tray slide mechanism 47 is used. Any suitable drive mechanism, such as a pushing or pulling drive mechanism such as a pusher, may be employed, and the sliding direction may of course be reversed.

Additional Relationships The vertical circulation parking device of Japanese Patent Application No. 58-231423, which is the original patent application, has multiple sprocket wheels connected via attachments to endless chains stretched across a pair of sprocket wheels installed vertically on both sides. In a parking device of the type in which a car storage cage is suspended and supported and each cage is vertically cyclically driven by rotating one side of the sprocket wheel by a suitable drive mechanism, the upper surface of the cage member of each storage cage is provided. A horizontal sliding tray and a fixed tray for mounting in a car are arranged adjacently from the back side in the longitudinal direction of the cage, and the horizontal sliding tray is placed in a pit corresponding to the lowest position of each storage cage. An elevating pedestal that rises or lowers, a trestle elevating mechanism that raises or lowers the elevating pedestal, and a tray slide mechanism that moves the horizontal slide tray placed on the elevating pedestal to either the left or right with respect to the direction of vehicle entry and exit. is provided, and when each of the storage cages reaches the lowest position, the pedestal lifting mechanism is operated to raise the lifting pedestal, and after placing the horizontal slide tray thereon, the tray sliding mechanism is raised. The present invention is characterized in that it is configured to operate and move the horizontal slide tray to carry in and out of a vehicle.

However, in such original patent application, 2
When a car is stored in a cage, 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 sideways and the stopping position after vertical circulation of the cage. On the other hand, in the present invention, 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 tray slide mechanism moves the elevating frame to compensate for the stop error of the re-cage. This is an improved system that corrects errors when landing on the cage by tracking the
