The swivel arm 10 is rotationally driven while being fitted, so that the traversing cart 6 is delivered between the elevator and each parking section.
[0006]
That is, in Japanese Patent Publication No. 7-33734, the swivel arm 10 is arranged in the center of the carrier, and a dog (engagement member 9) is attached to the free end side thereof. A transfer device is disclosed in which the pallet is traversed by turning the arm while fitting with the sliding plate 8).
[0007]
In the above-described conventional pallet transfer device, when the vehicle is released from one side of the parking shelf arranged on both sides of the elevator (carriage), the car can be stored only on the same side at the next warehousing, and similarly on the opposite side When leaving the store, there was a problem that it could only be stored on the opposite side at the next store.
[0008]
In order to solve this problem, the inventors of the present invention created and applied for a “pallet transfer device and an elevator-type parking device using the same” (Japanese Patent Application No. 9-93356, unpublished). As shown in FIG. 5, the present invention is a pallet transfer device 20 that moves a pallet 6 on which a vehicle is placed in the width direction (vertical direction in the figure), and guide rails that guide the pallet 6 to be horizontally movable in the width direction. 22, a swing arm 24 that can rotate forward and backward horizontally below the pallet 6, an engagement dog 26 provided at the free end of the swing arm 24, and a dog receiver 17 provided on the bottom surface of the width end of the pallet. A dog hoisting device 28 for raising and lowering the engaging dog between an upright position where the mating dog is fitted and a retracted position where the mating dog is not fitted, and the rotating shaft 24a of the swivel arm is substantially the same as that of the pallet transfer device. The center of the swivel arm is set such that the distance R between the rotation axis 24a and the engagement dog 26 is set to approximately ½ of the distance L between the dog receivers inside the pallet 6 located on both sides. It is what.
[0009]
According to the configuration of the pallet transfer device described above, as shown in FIG. 6, the swivel arm is moved from an oblique position (standby position A) where the dogs 26 provided at the free ends of the swivel arm are not engaged with the pallets 6 on both sides. Is rotated to a position C extending perpendicularly to one of the adjacent pallet sides, thereby engaging the dog receiver 17 (see FIG. 5) provided on the bottom surface of the width end of the pallet with the dog 26 of the swivel arm. Furthermore, the pallet 6 can be transferred directly above the pallet transfer device 20 by rotating the swivel arm 24. Therefore, by this operation, the pallet 6 can be transferred onto the pallet transfer device from any of the adjacent parking shelves 3 arranged on both sides, and vice versa. The pallet 6 can be transferred from the pallet transfer device to either of the parking shelves 3.
[0010]
[Problems to be solved by the invention]
However, the pallet transfer device described above can freely transfer (transfer) the pallet to and from the adjacent parking shelf 3, but the transferred pallet can be transferred to the pallet transfer device as in the berth for loading and unloading. There was a problem that it was not possible to traverse from the adjacent position to the position.
[0011]
In order to solve this problem, (1) “three-dimensional parking device” (Japanese Patent Laid-Open No. 4-27082), (2) “elevator type parking device pallet transfer device” (Japanese Patent Laid-Open No. 4-131476), 3 “Elevator type multi-story parking device” (Japanese Patent Laid-Open No. 2-200975) has been proposed, and all of them are moved slightly from the adjacent position to the back by the pallet transfer device provided in the lifting device (carriage). However, there was a problem that the transferred pallet could not be traversed freely to a further distant position. For this reason, there was a problem that the entry / exit berth is narrow and entry / exit is difficult.
[0012]
In other words, in the conventional pallet transfer mechanism, a system is widely adopted in which a dog is attached to the circulation chain on the lifting device and is engaged with the pallet. It is common to transfer the pallet between another transfer device or a parking shelf using the state where the chain attached to the sprocket part and the dog is separated from the linear track, but such a conventional pallet transfer In the loading device, when a dog is attached to the chain and the pallet is transferred, a reaction force acts in the direction of bending the chain, so a guide is necessary, and it is difficult to reliably guide both the straight part and the sprocket part. Therefore, there is a problem that the reliability of the operation is lowered.
[0013]
The present invention has been made to solve the various problems described above. That is, an object of the present invention is to allow a pallet traversed to a predetermined position by another apparatus to freely traverse to a further distant position by a stable mechanism with high reliability, and to disengage the apparatus. An object of the present invention is to provide a pallet traversing device that can traverse from a position.
[0014]
[Means for Solving the Problems]
