2. Description of the Related Art Conventionally, in a manufacturing process of a hard disk or the like used for a memory of a computer or the like, a disk having a hole for mounting a rotary shaft at its center is transferred. For mounting, a transfer bar was inserted into the center hole of the disk stored in the cassette at a predetermined pitch, the disk was scooped up from the cassette case, and transferred to another cassette case.

Further, since the storage pitch of the cassette case may be different depending on the process, in the case where the storage pitch needs to be changed, a plurality of pieces having a groove for receiving the center hole of the disk are mounted on the axis of the transfer bar. It was assembled slidably. After inserting the pieces of such a transfer bar into the center holes of a plurality of disks and scooping the disks out of the cassette case, sliding the pieces changes the disk storage pitch and transfers them to another cassette. Was there.

However, as the disk size of a hard disk having a central hole is reduced, the diameter of the central hole becomes smaller, making it difficult to form a mechanism for pitch exchange on the transfer bar. On the other hand, in the case of disks without a center hole, the disks were taken out one by one with tweezers and transferred, or transferred with a very complicated device. Therefore, a large amount of labor costs and equipment costs are required.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the work transfer machine of the present invention will be described below with reference to the drawings. As shown in FIG. 1A, the work transfer machine of the present invention receives a hard disk 9 which is a work housed in a cassette case 13, and a hard disk receiving device 3 which is a work receiving means for vertically moving the work.
The hard disk transfer device 2 is a work transfer means for transferring the hard disk 9 from a predetermined cassette case 13 to another cassette case.

The hard disk receiving device 3 is provided with a hard disk receiving base 10 which is a comb-like work receiving member in order to push up the hard disk 9 in the cassette case 13 just below the cassette case 12, and is provided with a cylinder (not shown) or the like. The hard disk pedestal 10 composed of the output shaft drives the hard disk pedestal 10 up and down by the output shaft 12. Since the hard disk pedestal 10 is formed in a comb tooth shape, the hard disks 9 housed in the cassette case 13 can be lifted together.

The hard disk transfer device 2 has a hard disk receiving piece 4 having a receiving groove 15 for receiving the outer peripheral portion of the hard disk 9, and a plurality of hard disk receiving pieces 4 inserted therein. It is composed of shafts 5 and 6 which are fixed receiving piece insertion members, and a receiving piece drive plate 11 which is a moving member for moving the plurality of hard disk receiving pieces 4 inserted in the shafts 5 and 6.

The hard disk receiving piece 4 includes shafts 5 and 6.
A plurality of hard disk receivers 4 mounted on the shafts and located at the respective tips of the shafts 5 and 6 are fixed to the shafts 5 and 6, respectively. Further, the rearmost hard disk receiving piece 4 is fixed to the receiving piece drive plate 11. The receiving piece drive plate 11 is slidably penetrated by the shafts 5 and 6 and is fixed to the cylinder output shaft 7.

The shafts 5, 6 and the cylinder 17 are fixed plates 8
Fixed to. As shown in FIG. 1 (b), the other hard disk receiving pieces 4 except the front and rear hard disk receiving pieces 4 are, for example, a hard disk receiving piece 4A and a receiving piece connecting screw 14
Has a female screw, and the receiving piece connecting screw 14 is the sleeve 1
It is tightened through 6. The other hard disk receiving piece 4 has a hole at the position where the receiving piece connecting screw 14 passes, which is larger than the outer diameter of the sleeve 16 and smaller than the diameter of the head of the receiving piece connecting screw 14. Further, there is a hard disk receiving piece 4C on the screw head side of the hard disk receiving piece 4B, and when the interval between the hard disk receiving pieces 4A, 4B, 4C is reduced by the cylinder output shaft 7, the head of the receiving piece connecting screw 14 is the hard disk receiving piece. It is configured so as to enter the hole of the piece 4C.
Therefore, the pitch is determined by the thickness of the receiving piece when contracted most, and the thickness of the receiving piece and the sleeve 1 when expanded most.
The pitch is determined by the length of 6.

Therefore, when the cylinder output shaft 7 presses the hard disk receiving piece 4 toward the tip side, all the hard disk receiving pieces 4 come into close contact with each other and are pressed against the hard disk receiving piece 4 at the end, and the cylinder output shaft 7 fixes the fixed plate 8 When it is pulled by, the receiving pieces are pulled one after another through the receiving piece drive plate 11 and stopped by the hard disk receiving piece 4 at the tip, so that the pitch can be varied. Further, the fixed plate 8 is gripped by a moving body such as a robot (not shown) and various operations are possible.

The operation of the work transfer machine configured as described above will be described below. First hard disk cradle 1
0, the hard disk 9 in the cassette case 13 is pushed up by the hard disk receiver 10 so that the hard disk transfer device 2 sandwiches the hard disk receiver 10 of the hard disk receiver 3 between the shafts 5 and 6. The hard disk 9 can be placed on the hard disk receiving piece 4 inserted into the shafts 5 and 6 by entering under 9 and then lifting the hard disk transfer device 2 or lowering the hard disk receiving base 10. The hard disk transfer device 2 is moved to another place by a robot or the like, and the hard disk 9 is transferred to another hard disk pedestal 10 having the same structure and installed therein, and the hard disk transfer device 2 is moved by the robot or the like. After pulling out, by lowering the hard disk receiving base 10, it becomes possible to transfer the hard disk 9 to another cassette case.

At this time, if the cassette cases have different storage pitches, the pitch can be changed by moving the receiving piece drive plate 11 by the cylinder 17. If there is no need to change the storage pitch at all, the hard disk transfer device 2 may be simply a bar having a receiving groove. Further, although the hard disk transfer device 2 is described as being moved by a robot, the cassette case 13 and the hard disk receiving device 3 may be moved.

[0017]

As is apparent from the above embodiments, the work transfer machine according to the present invention is capable of transferring the works collectively from the cassette case to the cassette case, and various cassette cases. It is possible to change the storage pitch every time, and its economic and technical effects are remarkable.
