JP7595916B2 - Traversing device for multi-storey car parks - Google Patents

Description

The present invention relates to a traverse device for a multi-story parking system that is installed in the multi-story parking system and moves pallets carrying vehicles traversely between a carrier and a parking space.

A multi-story parking system has a vertical elevator shaft in the center of a building erected on the ground, with parking spaces arranged in a tiered manner in the space on either side or both sides of the elevator shaft, and vehicles are transported between the entrance/exit gates and the parking spaces by elevators to store or remove them. It is widely used as parking facilities in densely populated urban areas and as ancillary equipment for commercial facilities. One type of multi-story parking system involves loading vehicles onto a pallet, and transporting and storing/removing the vehicles together with the pallet.

This pallet-type multi-story parking system is roughly configured as follows: Each parking space on each level is provided with two lateral rails adjacent to the elevator shaft, parallel to the sliding direction of the pallet, with multiple rollers rotatably arranged along the lateral rails, and each parking space is provided with a pallet supported on these rollers (see, for example, Patent Document 1). Similarly, rollers are arranged on the carriage of the elevator lift to support the pallet so that the pallet can move toward the parking space, and a lateral drive device is provided to move the pallet between the carriage and the parking space. Known lateral drive devices include a device in which a chain has a drive pin that can be engaged and disengaged with the pallet, and the drive pin engages with the pallet to drive the chain to move the pallet (see, for example, Patent Document 2), and a device in which the pallet is moved by the rotational movement of a swivel arm that rotates horizontally (see, for example, Patent Document 3). In a lift, one end of a wire rope is connected to the four corners of the carrier that carries the pallet and vehicle, this wire rope is wound around a drive device installed at the top of the building, and a counterweight is connected to the other end of the wire rope. By driving the wire rope, the carrier rises and falls like a bucket up the elevator.

In this configuration, when a vehicle is first stored in the parking device, the carriage of the lift is raised and lowered to a parking space where no vehicle is stored, and an empty pallet is moved from the parking space onto the carriage by the lateral drive device attached to the carriage, and then the carriage is driven again to raise and lower it to the entrance and exit of the vehicle. Then, after the vehicle is loaded onto the pallet at the entrance and exit, the carriage is raised and lowered to the parking space from which the pallet was previously pulled out, and the pallet and the vehicle are moved into the parking space and stored by the lateral drive device. When a vehicle is removed from the parking device, each operation is performed with the above operations reversed, with or without the vehicle loaded on the pallet. In other words, the vehicle is transferred from the parking space where the vehicle was stored onto the carriage together with the pallet and raised and lowered to the entrance and exit, and after the vehicle has left, the empty pallet is raised and lowered to the designated parking space, and the pallet is placed back in the parking space.

However, conventional traverse devices installed on carriers have multiple electric motors to move the pallets evenly, and the front and rear drive units are connected by universal joints, etc., making the structure complex and heavy. For this reason, the object of the present invention is to provide a traverse device for a multi-story parking system that can simplify the structure and reduce weight.

In order to solve the above problem , the invention of claim 1 provides a multi-story parking system comprising an elevator having a space penetrating in the vertical direction, parking spaces arranged in multiple levels vertically along the elevator, a pallet arranged to be able to move laterally in the parking spaces, a carriage carrying the pallet and moving it up and down the elevator, and a carriage attached to the carriage for moving the pallet laterally between the parking spaces and the carriage, the lateral movement device comprising a first lateral movement drive gear driven by an electric motor, a second lateral movement drive gear meshing with the first lateral movement drive gear, a first driven sprocket rotated by a first drive chain hung on the first lateral movement drive gear, a second driven sprocket rotated by a second drive chain hung on the second lateral movement drive gear, a pair of engagement arms which rotate horizontally in opposite directions together with the first driven sprocket and the second driven sprocket, and an engagement roller provided at the tip of the engagement arm and which engages with the pallet .

According to the present invention, the traverse device of the present invention is configured by meshing two traverse drive gears, rotating one traverse drive gear and the other traverse drive gear in different directions, and transmitting this through a chain to rotate the engaging arm, resulting in a simple and lightweight configuration with fewer components.

The following describes an embodiment of the present invention with reference to the drawings. Figures 1 and 2 are a front view and a side view showing an outline of a multi-story parking system.

A multi-story parking device 10 has a hoistway 11 that runs vertically through the center, and a lift 12 that can move up and down the hoistway 11. The lift 12 has a carriage 13 for transporting a vehicle 19, a wire rope 14 that suspends the carriage 13, a hoisting device 15 installed at the upper end of the hoistway 11, and a counterweight 16 that balances the weight of the carriage 13 via the wire rope 14, and is configured as follows: One end of the wire rope 14 is connected to each of the four corners of the carriage 13, and the wire rope 14 is wound around the hoisting device 15 provided at the upper end of the hoistway 11, and the other end is connected to the counterweight 16. The hoisting device 15 has an electric motor 21, a reducer 22, and a drive sheave 23, and the drive sheave 23 is rotated by the power of the electric motor 21, and the wire rope 14 is wound around the drive sheave 23. Then, by controlling the motor 21 to rotate forward or backward, the carriage 13 rises or falls within the elevator shaft 11.

On both sides of the elevator 11, multiple parking spaces 17 are formed in multiple levels, and vehicles 19 transported by the carriage 13 are stored. In each parking space 17, two lateral guide rails 20 are fixedly installed extending from the elevator 11 side toward the side so as to be located near the front end and rear end of the vehicle 19. Along the longitudinal direction of each lateral guide rail 20, multiple guide rollers 24 are rotatably supported at a predetermined interval, and a pallet 18 is placed on these guide rollers 24 provided on the two opposing lateral guide rails 20, and the pallet 18 is provided in each parking space 17 so as to be slidable in the elevator 11 direction. On the other hand, the carriage 13 of the elevator lift 12 is configured to slidably support the pallet 18 on its upper surface in the same way as the parking space 17, and is equipped with a lateral drive device that moves the pallet 18 back and forth between the parking space 17 and the carriage 13.

In this configuration, the vehicle 19 is loaded onto the pallet 18 and transported and stored together with the pallet 18. That is, when the vehicle 19 enters the warehouse, the empty pallet 18 is pulled out from the empty car parking space 17 and loaded onto the carrier 13, after which the carrier 13 ascends and descends to the loading/unloading level and stops, and the vehicle 19 enters the pallet 18 on the carrier 13. Next, the carrier 13 ascends and descends together with the loaded pallet 18 and the vehicle 19, stops at a specified parking space 17, and sends both the pallet 18 and the vehicle 19 into the parking space 17 for storage. Conversely, when leaving the warehouse, the pallet 18 carrying the vehicle 19 is pulled out onto the carrier 13, the carrier 13 ascends and descends to the loading/unloading level and stops, and the vehicle 19 leaves the warehouse under its own power. In this way, the pallet 18 is slid between the parking space 17 and the carrier 13, and for this reason, the parking space 17 is provided with multiple guide rollers 24 as described above, which support the pallet 18 so that it can move between the parking space 17 and the carrier 13.

Figure 3 is a plan view of the traverse device 25 provided on the carriage 13, and Figure 4 is a front view of the traverse device 25. A geared motor 27, which combines an electric motor and a reducer, is fixed to the frame 26 of the carriage 13, and a drive gear 28 is fixed to the output shaft of this geared motor 27. A driven gear 29 that meshes with the drive gear 28 is rotatably supported on the frame 26, and the driven gear 29 rotates when the geared motor 27 is driven.

The driven gear 29 is connected to a gear shaft 33, which has a first transverse drive gear 31 fixed to its upper end via a joint 30, and the gear shaft 33 or the first transverse drive gear 31 rotates with the rotation of the driven gear 29. A second transverse drive gear 32 meshing with the first transverse drive gear 31 is rotatably supported on the frame 26, and the first transverse drive gear 31 and the second transverse drive gear 32 rotate in opposite directions.

A first driving sprocket 34 and a second driving sprocket 35 are fixed to the top of the first traverse drive gear 31 and the second traverse drive gear 32, respectively. On the other hand, a first driven sprocket 38 and a second driven sprocket 39 are provided at both ends of the traverse device, and a first driving chain 36 is wound between the first driven sprocket 38 and the first driving sprocket 34, and a second driving chain 37 is wound between the second driven sprocket 39 and the second driving sprocket 35. The first driven sprocket 38 and the second driven sprocket 39 rotate as the first driving chain 36 and the second driving chain 37 move.

The first driven sprocket 38 and the second driven sprocket 39 are equipped with an engagement arm 40 that rotates together with the first driven sprocket 38 and the second driven sprocket 39. A support pin 42 with an engagement roller 41 at its end that can rotate freely is fixed to the tip of the engagement arm 40 so that it protrudes upward. Meanwhile, a groove member 43 that opens downward is formed on the underside of the side of the pallet 18, and the engagement roller 41 and the groove member 43 engage with each other during lateral movement to move the pallet 18 laterally.

With the above configuration, the traverse device 25 operates as follows. Figure 5 shows the state of the traverse device 25 when the carriage 13 ascends or descends within the elevator shaft 11, with the engagement arm 40 of the traverse device 25 being parallel to the longitudinal direction of the carriage 13. This prevents the engagement arm 40 from coming into contact with other components within the multi-story parking device 10 while the carriage 13 ascends or descends.

Figure 6 shows the state when the hook roller 41 of the hook arm 40 provided on the traverse device 25 hooks up with the groove member 43 of the pallet 18. When the traverse device 25 reaches the target position of the pallet 18, the geared motor 27 is operated to drive each part, causing the hook arm 40 to rotate in the direction of arrow A, and the hook roller 41 hooks up with the groove member 43.

Figure 7 shows the state in which the pallet 18 has traveled laterally and reached a predetermined position on the carrier 13. After the engagement rollers 41 and the groove member 43 have engaged, the geared motor 27 continues to operate to rotate the engagement arm 40 in the direction of arrow B, and the pallet 18 moves laterally in the direction of arrow C due to the rotation of the engagement arm 40. When the pallet 18 reaches a predetermined position, the operation of the geared motor 27 is stopped to end the lateral movement. The carrier 13 then moves up and down within the elevator shaft 11, transporting the pallet 18 with the engagement rollers 41 and the groove member 43 engaged. When the pallet 18 is to be stored in the parking space 17, the above-mentioned operations are reversed.

As described above, the traverse device of the present invention is configured by meshing two traverse drive gears and rotating one traverse drive gear and the other traverse drive gear in different directions, which is transmitted by a chain to rotate the engagement arm, resulting in a simple and lightweight configuration with few components. In addition, since only a single electric motor is required as a drive source, it can be constructed at low cost. Furthermore, when the carrier moves up and down in the elevator shaft, the pallet is transported with the engagement roller and groove member engaged as described above, so the pallet can be transported in a stable state without shifting.
