BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an article transferring suction apparatus for transferring a flat product such as an optical disk from a single process to another process in a manufacturing process of the flat product. .

[0002]

2. Description of the Related Art Conventionally, in a process of manufacturing an optical disc, for example, an optical video disc or a compact disc, when an optical disc (hereinafter, simply referred to as a disc) is transferred, an inner peripheral portion (disc) which is not a recording portion is used. A plurality of (actually three or more) small suction disks are brought into contact with a portion of the player which is held between the turntable and the clamper, and the air in the space between the suction disk and the disk surface is suctioned by a pump. The disk has been transferred by moving the suction disk.

[0003]

Since the suction portion of the video disk or the compact disk by the suction disk has a relatively large area, a plurality of suction disks can be simultaneously suctioned and transferred. In the case of a disk such as a mini-disc having a very small area of the inner peripheral portion other than the recording portion, it is impossible to simultaneously transfer a plurality of suction disks by sucking them as in the related art.

[0004] For this reason, there is no other choice but to suck and transfer the disk by one or two suction disks. If the number of the suction disks is small, the suction force is weak, so that the disk may drop during the transfer or the disk may tilt during the transfer. As a result, there arises a problem that the disk cannot be transferred to the next step or that the disk cannot be set at a normal position at the transfer destination.

SUMMARY OF THE INVENTION The present invention is intended to solve the above-mentioned problems. The purpose of the present invention is to make the suction portion of the suction device ring-shaped so as to increase the suction area, and to increase the inner and outer rings of the suction device. An object of the present invention is to provide an article transfer suction device that can provide a step by providing a step in a crease portion and reliably suck and transfer even an article having a ring-shaped step.

[0006]

The object of the present invention is to attain the object mentioned above, which comprises a cylindrical body made of an elastic material such as silicone resin and the like. A plurality of air holes are formed in the direction, and a flange is formed at one end of the main body, and a ring-shaped fold having a thickness decreasing toward the front end is communicated with the air hole at the other end to form two air holes. A suction hole formed and having one length of the two folds different from the other length, a suction hole having a concave portion in which the flange portion of the suction device is housed, and communicating with the air hole. Are formed, and a ring-shaped fixing plate that is fixed to the mounting base by sandwiching a flange portion inserted into the recess of the mounting base.

[0007]

In the article transfer suction device according to the present invention having the above-described structure, two ring-shaped folds are formed at one end of the ring-shaped suction tool, and air is sucked between the two folds. As a result, the suction area is increased and the suction force is increased, so that the article can be reliably sucked. In addition, since the length of one of the two folds is made different from the other, the article has a ring shape. Even if the stepped portion is formed, suction can be performed.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. Reference numeral 1 denotes a suction tool formed of an elastic material such as a silicone resin, and is formed in a cylindrical shape as a whole. A flange 11a protruding in the outer peripheral direction is formed at one end (left side in FIG. 1) of the main body 11 formed in a cylindrical shape.
At the other end, two ring-shaped folds 12 and 13 whose thickness decreases toward the tip are formed to extend from the outer peripheral wall and the inner peripheral wall of the main body 11.

The fold 1 extending from the outer peripheral wall
2 has a shorter length than the fold 13 extending from the inner peripheral wall. A plurality of air holes 11b are formed in the main body 11 in the axial direction, and the air holes 11b communicate with a ring-shaped groove 14 formed between the folds 12, 13.

Reference numeral 2 denotes a ring-shaped mounting base for mounting the suction tool 1, and a ring-shaped concave portion 2a for fitting a flange portion 11a of the main body 11 is formed on the inner peripheral lower surface side. A ring-shaped communication hole 2b is formed in a state further depressed than 2a. In addition, a plurality of suction holes 2c (eight in the embodiment) communicating with the communication holes 2b are formed in the mounting base 2 in the axial direction.

Reference numeral 2d denotes a connection hole with a pipe for connection to a vacuum pump (not shown), and reference numeral 2e denotes a screw hole (four in the embodiment). 3 is the suction device 1
When the flange 11a is fitted into the recess 2a of the mounting base 2, a ring-shaped fixing plate is inserted into the suction tool 1 from the back side, and a plurality of holes 3a for inserting the screws 4 ( In the embodiment, four are provided. Then, the suction tool 1 can be fixed to the mounting base 2 by inserting the screw 4 into the hole 3a and screwing it into the screw hole 2e of the mounting base 2 and tightening.

5 is a mini-disc which is a transfer article,
The upper surface is a recording surface, and a hole 5a for inserting a turntable spindle is formed in the center. A step 5 is provided on the inner peripheral side of the recording surface of the mini disc 5.
b is formed.

Then, the center axis of the mini-disc 5 is moved in accordance with the center axis of the suction tool 1, and the mounting base 2 is lowered to press the folds 12, 13 of the suction tool 1 against the mini-disc 5. At this time, since the length of the fold 12 is different from the length of the fold 13, and the step 5b is formed on the mini-disc 5, as shown in FIG.
13 is pressed against the surface of the mini-disc 5 without any gap.

In this state, the suction hole 2c and the communication hole 2
b, the air in the ring-shaped groove 14 formed by the folds 12, 13 is sucked through the air hole 11b. As a result, a negative pressure is generated in the ring-shaped groove 14, so that the mini-disc 5 is sucked.

Since the length of the folds 12 and 13 is substantially equal to the depth of the step 5b of the mini disk 5, the folds
Since there is no gap between the tips of the discs 2 and 13 and the surface of the mini-disc 5, the mini-disc 5 can be reliably sucked. Therefore, by moving the mounting table 2,
The mini disk 5 can be transported reliably.

Further, since the portion for sucking the mini-disc 5 is formed in a ring shape, the suction area is larger than that of the conventional disk-shaped suction disk, and therefore, the suction force is strong.

[0017]

According to the present invention, as described above, two ring-shaped folds are formed at one end of the ring-shaped suction device, and air is sucked between the two folds. Since the area is increased and the suction force is increased, the suction of the article can be reliably performed. In addition, since the length of one of the two folds is different from that of the other, it is very small, such as a mini disk. Even if the article has a limited suction portion and has a ring-shaped step, the article has such an effect that suction can be performed.
