ζEquipped with a pair of load holders that can move toward and away from each other. Loads are received and transferred to and from the target compartment storage space by a combination of running action, lifting and lowering movements, left and right movement, and movement towards and away from each other.

Problems to be Solved by the Invention According to the above-mentioned conventional type, since a fork-type load holder is used, a long sliding contact occurs when the worker goes to and from work, and this sliding contact generates dust. For this reason, it cannot be easily adopted in clean rooms. In addition, when the stroke of egress and egress is long, it is possible to
This will further increase the number of sliding contact areas.

Furthermore, it would be fine if the shelves were placed on one side as in the conventional format, but if the shelves were placed on both sides,
Since the load holder must protrude from both sides,
The number of sliding contact parts will further increase.

It is an object of the present invention to
The object is to provide a pre-cutting device that is almost completely eliminated regardless of the length of the stroke or the direction of action.

The operation of the above embodiment will be explained below. Inside the clean room 1, the clean air 4 that is blown downward through the filter 3 descends, and the descending air is sucked below the floor 5, so that its cleanliness is ensured. In this way, using the loading/unloading device 15 in the lean room 1, the compartment storage space 14 for the purpose of the shelf 6 and the double cylinder holder 1 are used.
2 and 18, the loading/unloading device 15 travels on a fixed path 16 and the lifting platform 48
This can be achieved by a combination G of the lifting and lowering operation of the load holding device 44 and the operation of the load holding device 44.

The holding operation by the load holding device 441 is performed as follows. The case frames 70A, 70B, etc., which go to receive the load 45, are spaced apart from each other. First, with the lifting platform 48 stopped corresponding to the intended storage space 14i, the motor 50 of the swinging device 49 is started, and the output shaft 58 is rotated in the same direction via a worm reducer 52 or the like. . As a result, the output shaft 58 is connected to the cylindrical body 55A.
, the first case frame 70 is integrated via 55B.
A and 70B are swung toward the divided storage space 14 around the output shaft axis 58a. At this time, the first chain ring 78A.

Since the position of 78B is fixed, the first case frame 70A
, 70B, the longitudinal shafts 72A, 72B are rotated via the second chain rings 79A, 79B, and the longitudinal shafts 72., 70B rotate. A, 72B i The second case frame 78A is integrated with the second case frame 78A.

71B has twice the swing angle 2θ. The first case frame again? The longitudinal axis 72A, 7 due to the swing fζ of OA, 70B
A part of the downward movement of the case frame 2B is absorbed by the rise of the support bins 74A and 74B due to the swinging of the @2 case frames 71A and 78B, so the load holders 76A and 76B move at approximately the same level. Furthermore, the first case frame 70A, 70
Since the third chain rings 81A, 81B are fixed to B, depending on the amount of swing of the second case frames 78A, 78B, the movement of The support bins 74A and 74B are rotated, and both front holders 76A
, 76B are maintained in their normal upward postures. This operation causes the load holders 76A and 76B to hold the target load 45.
The approaching/separating device 60 is operated while being positioned outside both sides of the locking portion 45a and at a lower level than the locked portion 45a. That is, starting the motor 61 (starting the output shafts 63A, 68B)
are rotated in opposite directions to move both nut bodies 65A and 65B closer together. As a result, the movable table 57A is guided by the v-/L/ bodies 58A and 58B.

57B move closer to each other, and the first case frames 70A and 70B
etc., to position the load holders 76A and 76B directly below the locked portion 45a. Next, by slightly raising the lifting platform 48, the load holders 76A and 76B are engaged with the locked portion 45a, thereby lifting the load 45. Then, the swinging device 49 is operated in the opposite manner to the above, and the first case frame is rotated.
By swinging the OA and 70B in an upright position, the held load 45 is positioned on the lifting platform 48.

The load 45 can be held by performing the operation opposite to that described above.
can be unloaded onto the receiving platform 18 for shipping. In addition, the receiving platform 18 for warehousing
The movement of the load 45 from the compartment storage space 14 can also be performed in the same manner.

In the above embodiment, the effect of the structure 1 on the shelf 6 on one side was described, but even if there is a shelf 6 on the opposite side as shown in the imaginary line in FIG. 1, the same effect can be applied to the shelves 6 on both sides. It can be done.

Effects of the Invention According to the present invention having the above configuration, when the first case frame is swung to one angle in the left-right direction by the actuating device, the second case frame is swung to the above-mentioned angle via the swing control device. , it is possible to swing the load holder to one side with respect to the first case frame at an angle proportional to a certain multiple, thus reducing the amount of drive of the actuating device (and shaking the load holder greatly without creating almost any sliding contact). In addition, the load holder can maintain a horizontal position under any swinging conditions.
Furthermore, by moving the first case frame toward and away from the actuating device, it is possible to perform holding and releasing movements for the load. As described above, according to the present invention, the sliding portion of the loading/unloading device can be almost eliminated regardless of the length of the Nutlok or the direction of action, and it can be particularly effectively employed in clean rooms.
