In FIG. 2, reference numeral 7 is a power cord connected to a drive motor 61, and is connected to a current collector 8 which passes through the swivel arm 2 and projects to the rear surface of the swivel arm 2 on the pivot side. The current collector 8 is connected to a power source through an output terminal 9 provided on the servomotor 4 of the turning drive device. With such a connection structure of the current collector 8 and the output terminal 9, the turning operation of the turning arm 2 is not hindered.

The vertical drive device 6 for the engaging member 3 is also
Instead of the linear head motor, an electric cylinder or a solenoid may be used.

Further, instead of the means for vertically moving the engaging member 3, a means for vertically moving the revolving arm 2 may be provided on the revolving drive device 4 side. In this case, the support shaft 32 of the engaging member 3 is fixed. Then, the drive motor 61 that moves the engaging member 3 up and down, and the cord 7 that connects the power source from the collector 8 side.
Etc. become unnecessary.

On the other hand, in the tray 14 for automatic vehicle mounting, angle-shaped guide members 15 with which the engaging members 3 of the tray transfer device 1 can be engaged are attached at predetermined positions on both sides in the longitudinal direction of the lower surface thereof. ing. Both ends of each of the guide members 15 are expanded outwardly so that the engaging member 3 that swivels can be reliably fitted. In the following description, on the lower surface of the tray 14, the guide member 15 closer to the carrier 11 side is referred to as an inner guide member 151, and the guide member 15 on the opposite side is referred to as an outer guide member 152 to distinguish them.

The construction of a plane reciprocating parking apparatus using the carrier 11 equipped with the tray transfer apparatus 1 will be briefly described with reference to FIG. In FIG. 3, reference numeral 12 is a transport path along which the transport vehicle 11 travels back and forth. 13 are storage chambers defined on both sides of the transport path, and trays 14 for automatic vehicle mounting are arranged in each of them. Reference numeral 16 is a lift that connects to the floor on which the vehicle is loaded, and 17 is a hoistway thereof, which is set in the row of the storage chambers 13 on one side (the right side in the drawing).

Next, the operation of the tray transfer device 1 will be described together with the operation of the planar reciprocating parking device with reference to FIGS. 3 to 6. In the tray transfer device 1, the operation of sending out the tray 14 drawn out from the storage chamber 13 in the right column to the storage chamber 13 and the lift 16 located in the same column is performed by the driving device of Japanese Patent Publication No. 7-33734. I will get it. That is, after the transport carriage 11 is moved to the storage chamber 13, the swivel arm 2 swivels to engage the engaging member 3 with the guide member 151 on the inner surface of the lower surface of the tray 14 to pull it onto the transport carriage 11, and to engage the engagement. After that, the transport vehicle 11 is moved in front of the other storage chamber 13 or the lift 16 on the same side, and then the tray 14 is sent out by turning in the direction in which the turning arm 2 is returned.

Here, using the drive device of the present application, the tray 14 on the storage chamber 13 located on the far left side in FIG.
A series of operations up to the step 6 will be described in detail.

In FIG. 3, first, the carriage 11 moves by itself on the carriage path 12 and is stopped at the rear end (upper side in FIG. 3). Next, in the tray transfer device 1 of the transport carriage 11, the rotation shaft 5 thereof is rotated by the operation of the servo motor 4, and the swing arm 2 swings from the initial stop position parallel to the transport path 12 toward the left storage chamber 13. I will do it. When the tip of the swivel arm 2 enters the storage chamber 13 and the entire swivel arm 2 is swung to a position perpendicular to the arrangement direction of the storage chambers 13, the engagement member 3 causes the tray 14 on the storage chamber 13 to move.
Into one end of the guide member 151 on the inside of the lower surface of the. FIG.
As shown in FIG. 5, the engaging member 3 moves along the guide member 151, and the tray 14 is pulled out in the swivel direction of the swivel arm 2 as the swivel arm 2 is swung, and is pulled onto the transport carriage 11. When the revolving arm 2 revolves to a position parallel to the longitudinal direction of the tray 14, the engaging member 3
Reaches the end of the guide member 151 inside the tray 14,
From here, as the revolving arm 2 revolves, the engaging member 3 moves in the direction of returning on the inner guide member 151. In this way, the turning arm 2 is stopped when the turning arm 2 moves to a predetermined turning angle, and the tray 14 is completely transferred onto the transport carriage 11. Then, the tray 14 is locked by locking means (not shown), and the state is fixed.

In this way, the tray 14 is moved to the carrier truck 11
When it is placed on the top, as shown in FIG. 5, the carrier 11 is moved by itself on the carrier path 12 toward the lift 16 this time. While the transport vehicle 11 is moving, the vertical drive device 6 of the engaging member 3 in the tray transfer device 1 starts to operate. That is, the operation of the drive motor 61 causes the drive shaft 62 to move downward, and the support shaft 32 of the engaging member 3 connected to the drive shaft 62 descends to the lower surface side of the revolving arm 2. Due to the lowering of the support shaft 32, the roller 31 is lowered downward to the upper surface position of the revolving arm 2, the engagement with the inner guide member 151 is released, and the operation of the drive motor 61 is stopped. When the engagement member 3 and the tray 14 are disengaged from each other in this manner, the rotation arm 2 is rotated by the operation of the servo motor 4 in the direction opposite to the direction in which the tray 14 is retracted, and the roller 31 and the roller 31 are released. The other outer guide member 152
The turning is stopped at the intersection with. Then, again by the operation of the drive motor 61 of the vertical drive device 6, the drive shaft 6
2 is moved upward, the support shaft 32 of the engaging member 3 is raised above the upper surface of the revolving arm 2, and the roller 31 is inserted and engaged with the outer guide member 152 from below. At this time, since the roller 31 has a truncated cone shape, that is, a taper shape in which the diameter gradually decreases from the lower portion to the upper portion, a slight deviation occurs between the stop position of the swing arm 2 and the position immediately below the outer guide member 152. However, the smooth engagement between the engagement member 3 and the outer guide member 152 can be obtained.

While the transport carriage 11 is moving, the engagement member 3 thus moves from the inner guide member 151 to the outer guide member 1 as described above.
The engagement is switched to 52, and the carriage 11 lifts 16
When it reaches the front, the vehicle is stopped. Then, the tray 14 is unlocked. Next, in the tray transfer device 1, the turning arm 2 is driven by the operation of the servo motor 4.
Rotates in the direction of the lift 16, the engaging member 3 moves along the outer guide member 152 as the rotating arm 2 rotates, and sends the tray 14 in the rotating direction of the rotating arm 2 from the transport carriage 11. It is sent to the lift 16.
When the revolving arm 2 revolves to a position parallel to the longitudinal direction of the tray 14, the engaging member 3 reaches the end of the outer guide member 152, and from there, the revolving arm 2 revolves and the engaging member 3 moves. It moves on the guide member 152 in the returning direction. As shown in FIG.
The tray 14 is completely transferred onto the lift 16 when the turning arm 2 turns to a predetermined turning angle. At the same time, the engaging member 3 is disengaged from the guide member 152 on the outside of the tray 14, and the swing arm 2 is swung to an initial stop position on the transport carriage 11 and stopped. The relationship between the inner and outer guide members 15 of the tray 14 moved from the left column to the right column is reversed. That is, after the movement, the one closer to the carrier 11 is the inner guide member 151, and the opposite is the outer guide member 152, which is the reverse of the state before the movement.

In FIG. 7, the storage room 1 located at the back of the left column
3 illustrates an operation example in which the tray 14 is transferred to the storage room 13 in the front of the right side column. Also in the series of operations in this case, each part of the device performs the same operation as described above.

As described above, according to the above-described embodiment, in the tray transfer device 1 of the carriage 11, the engaging member 3 is vertically displaced by the vertical drive device 6 for the engaging member 3. Yes, the engaging member 3 is pulled out from the inner guide member 151 to release the engagement, and the engaging member 3 is moved by turning of the turning arm 2 and then the engaging member 3 is inserted into the outer guide member 152 from below. Since the tray 14 can be engaged with each other, the inner guide member 151 is used for retracting the tray 14 onto the transport carriage 11, and the retractable storage chamber 1 is used.
In the case of transferring to the same side as 3, the swivel arm 2 can be returned to the delivery destination by returning the swivel arm 2 in the engaged state, and can be placed on the lift 16 on the side opposite to the storage chamber 13 of the pull-in destination. , When moving to another storage chamber 13, by switching the engagement of the engagement member 3 from the inner guide member 151 to the outer guide member 152 by the vertical drive device 6 for the engagement member 3, Can be sent to the delivery destination.

Therefore, by one carrier truck 11,
Putting the tray 14 in and out between the storage chambers 13 on the same side, and putting the tray 14 in and out between the storage chambers 13 on different sides,
Further, it can be transferred to the lift 16 and the like, and the operation form of the carrier vehicle 11 can be expanded to efficiently carry out a preliminary operation for loading and unloading of the parking apparatus as a whole to realize a quicker and smoother loading and unloading of the vehicle. be able to.

Further, as shown in the plane reciprocating parking apparatus of FIG. 3, by mounting the tray transfer apparatus 1 on the carriage 11, the position of the lift 16 can be set in the row of one of the storage chambers 13. , It can be arbitrarily set according to the configuration of the parking lot installation space. Therefore, the entire parking system can be set up by effectively setting the car entry floor in a corner of a building to secure an effective space on the building side. It can be installed efficiently in the installation space.

[0031]

As is apparent from the above-described embodiment, the present invention has guide members arranged on both sides of the tray lower surface, and a vertical drive device for vertically displacing the engaging members. Since the engagement can be switched from one guide member to the other guide member, the tray can be transferred to the transfer destination on the opposite side to the drawing-in destination, and this tray transfer device can be lifted or transported. By mounting the vehicle on a dolly or the like, the parking apparatus as a whole can efficiently perform a preliminary operation for loading and unloading, and realize a quicker and smoother loading and unloading of a vehicle. In addition, by using this tray transfer device in various parking devices, it is possible to install the lift in any position such as setting a row in the storage room, and efficiently set the entry floor of the car in a corner such as a building.
