TECHNICAL FIELD OF THE INVENTION
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pallet exchange type parking lot vehicle lateral transfer apparatus which mainly adopts a pallet exchange type and places a car on or off a pallet between a traveling vehicle and a passenger compartment by moving laterally.
[0002]
[Prior art]
In the pallet exchange type parking lots that have been adopted in recent years, with the car on the pallet, lower it to the required floor with a lift etc., and move along with the pallet via the traveling cart waiting there and enter the warehouse And move laterally to the passenger compartment.
[0003]
In this case, first, the car mounted on the pallet on the lift moves laterally from the lift to the traveling vehicle together with the pallet, and at the same time, laterally moves the empty pallet of the traveling vehicle to the lift side, and then the traveling vehicle attempts to enter the warehouse. Cars that move to the cabin and are placed on the pallet on the traveling trolley move from the traveling trolley along with the pallet to the interior of the cabin, and at the same time, move the empty pallet in the cabin to the traveling trolley side. ing.
[0004]
That is, the transfer of an empty pallet is performed simultaneously with the transfer of an actual pallet on which a car is mounted, thereby realizing a short entry / exit cycle time equivalent to a palletless type.
As described above, in the conventional pallet exchange type parking lot, the power of the driving device or the actuator for pallet processing is not only provided on the side of the traveling bogie, but also in a single-row or double-row compartment. In some cases, the pallet side is also required, which causes a problem that the equipment cost increases, and also a problem that the processing mechanism of the empty pallet becomes complicated.
[0005]
[Problems to be solved by the invention]
The present invention has been made in view of such a conventional problem, and has as its object to provide an actuator for laterally moving a car even in a single train room or a double train room in a pallet exchange type parking lot. A pallet-exchange type parking lot vehicle that can be provided only on the traveling trolley and does not need to be provided in the passenger compartment, and the actual pallets and empty pallets can be exchanged with one actuator to simplify the processing of empty pallets. A horizontal transfer device is provided.
[0006]
[Means for Solving the Problems]
The pallet-exchange parking vehicle lateral transfer device of the present invention comprises a traveling bogie and an upper roller and a lower spring-loaded roller pressed against the upper roller in a vehicle room disposed on at least one side thereof. A heavy roller mechanism is provided, and an actual pallet on which a car is mounted is provided on the upper roller, and an empty pallet is provided between the upper roller and the lower roller so as to be laterally movable. Only the roller rotation actuator is provided.
Further, in the present invention, the vehicle room provided with the double roller mechanism in the above-described device is provided in a double row system.
[0007]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 shows a vehicle lateral transfer device in a pallet changeable parking lot, showing a state immediately before a vehicle 2 on a pallet 1 is laterally transferred from a traveling trolley 3 to a passenger compartment 4, and shows a pallet 1 on which the vehicle 2 is placed. On the other hand, an empty pallet 11 is placed in the cabin 4 provided on one side of the traveling vehicle 3.
[0008]
Further, as shown in FIGS. 4 and 6, a double roller including an upper roller 5 and a lower roller 6 with a spring 8 that presses the upper roller 5 from below is provided in the traveling carriage 3 and the cabin 4. Each of the mechanisms 7 is provided.
On the other hand, the pallet 1 on which the wheel 2 is mounted is placed on the upper roller 5, and an empty pallet 11 is placed between the upper roller 5 and the lower roller 6 in the direction of arrow H (see FIG. 1) They are provided so as to be able to move laterally in opposite directions.
[0009]
Further, as shown in FIGS. 4 and 5, only the double roller mechanism 7 of the traveling vehicle 3 rotates the upper roller 5 of the double roller mechanism 7 via the rotating shaft 12, the sprocket 13 and the chain 14. 9 (see FIG. 6).
In the pallet exchange type vehicle lateral transfer device having the above-described configuration, the traveling carriage 3 and the cabin 4 are each provided with a double roller mechanism 7 including an upper roller 5 and a lower roller 6 with a spring 8. An actuator 9 for rotating these rollers is provided only on the traveling carriage 3, and the upper rollers 5 of each double roller mechanism 7 are connected and linked by a chain 15 so as to rotate together. I have.
[0010]
Next, the operation will be described.
As shown in FIG. 1, the pallet 1 on which the vehicle 2 on the traveling vehicle 3 is placed starts to move in the direction of arrow H by the rotation of the upper roller 5 of the double roller mechanism 7 driven by the actuator 9.
Next, as shown in FIG. 2, the pallet 1 moves laterally in the direction of arrow H until the pallet 1 straddles the upper roller 5 at each end of each of the double roller mechanisms 7 of the traveling carriage 3 and the cabin 4. The empty pallet 11 on the vehicle cabin 4 side also moves in the direction opposite to the arrow H by the frictional force between the upper roller 5 and the lower roller 6 and the pressing force by the spring 8.
[0011]
That is, the empty pallet 11 in the cabin 4 is moved onto the traveling trolley 3 by the reaction force of the pallet 1 on which the vehicle 2 laterally transferred from the traveling trolley 3 is loaded, until the state shown in FIG. Move sideways.
In the above-described embodiment, the vehicle compartment 4 is provided only on one side of the traveling vehicle 3. However, the present invention is not limited to this. For example, the invention is also applicable to a case where the vehicle rooms 4 are provided on the left and right sides of the traveling vehicle 3. it can.
[0012]
Further, as shown in FIG. 7, the present invention can be applied to a case where a double-row cabin 4 is provided on one side of the traveling vehicle 3. In this case, the double-row cabin 4 can be provided on both left and right sides of the traveling bogie 3. In any case, the actuator 9 is not provided in each double roller mechanism 7 of the cabin 4 and the traveling bogie 3 is provided. The actuator 9 is provided only for the.
Next, the removal of the vehicle 2 which is laterally transferred to the state of FIG. 3 in the vehicle room 4 and leaves the vehicle 2 on the pallet 1 from the vehicle room 4 is performed in the reverse of FIGS. 1, 2 and 3 described above. It can be done by following the procedure.
[0013]
【The invention's effect】
As described above, according to the pallet-exchange-type vehicle lateral transfer device of the present invention, the actuator for laterally transferring the vehicle between the traveling vehicle and the vehicle compartment is provided only in the traveling vehicle, Need not be provided, so that the equipment cost can be reduced, the cost is reduced, and the processing of empty pallets can be simplified.
Further, if a double-row cabin is provided on both sides of the traveling cart, cars can be stored in each compartment, and the storage efficiency can be improved.
