【Example】

 An embodiment of the automatic disc feeder of the present invention will be described with reference to the drawings. 1 to 3 show the entire structure of an automatic disc feeder, FIG. 1 is a plan view of the inside of the device, FIG. 2 is a front view, and FIG. 3 is a side view. In FIG. 1, the upper plate is removed. In FIGS. 2 and 3, the side plate is partially cut away to show the inside. The automatic disk supply device 1 partitions the inside of the frame body 2 into upper and lower parts by a base 3, the upper part is a part for handling the disk, and the drive device, the control device and the like are housed in the lower part.

In the upper portion for handling the disk, each side surface is covered with the side plate 4, and the upper surface is covered with the cover 5. On the front side, an opening 6 is provided in the lower part of the side plate 4 for the worker to access the inside. An operation panel 7 for operating the automatic disc feeder 1 is attached to the lower portion of the opening 6. An air purifier 8 is provided on the top cover 5 to prevent foreign matter from entering the air inside the device 1.

Next, the internal structure of the automatic disk feeder 1 will be described. A turntable 11 is provided on the base 3. On the turntable 11, eight sections A-H on which the disk holders 12 for stacking and holding a plurality of disks CD are placed are provided. The turntable 11 is rotated by a predetermined angle to sequentially move the sections A-H to the take-out position. In FIG. 1, section C is in the take-out position.

Positioning 14 is provided on the turntable 11 for fixing the position of the disc holder 12 when the disc holder 12 is placed in each of the sections A-H. Further, in this embodiment, since eight partitions are provided, a maximum of eight types of disks can be set and taken out in order. The disc holder 12 has a central axis 13, and a plurality of stacked discs CD are held by the disc holder 12 by passing the central axis 13 through a hole at the center of the disc.

A disk suction unit 16 is provided as a means for taking out the disk CD. Details of the disk suction unit 16 will be described later in detail. The disc suction unit 16 moves on the guide 17 and reciprocates between the take-out position (section C) and the tray holding portion 18. The disc adsorption unit 16 adsorbs and takes out the top disc among the disc CDs stacked on the disc holder 12, and places the discs CD on a tray (not shown) placed on the tray holding portion 18. Supply.

After the disc CD is stored in the tray, the disc is handled by the tray, so that the disc is not directly handled by hand or machine, and scratches and dust are not attached. . When the disc suction unit 16 returns to the take-out position again, the turntable 11 rotates by a predetermined angle until then, and the disc CD and the disc holder 12 placed in the next section are moved to the take-out position. The disc suction unit 16 performs the same operation as described below, and sequentially supplies the eight types of disc CDs to the tray on the tray holding unit 18.

Further, when the disc suction unit 16 takes out the discs CD one by one from the disc holder 12, a unit is provided for preventing two discs from being taken out together. As will be described later, the disk suction unit 16 itself has a function of preventing the removal of two disks. However, in this embodiment, the static elimination air nozzle 21 is further attached to the disk suction unit 16 so that two disks can be ejected. Mount the anti-pickup unit 22 on the base 3. The details of the static elimination air nozzle 21 and the two-disc protection unit 22 will be described later.

The disk suction unit 16 will be described. The disk suction unit 16 has three suction pads 23. When the disc CD is taken out, the disc suction unit 16 descends, and the suction pad 23 comes into contact with the uppermost disc of the stacked discs CD and sucks it.

Details of the suction pad 23 are shown in FIG. The three suction pads 23 are arranged at an equal distance from the center of the disc CD and distributed by 120 °. And, of the three suction pads, two suction pads are formed longer than the other one. Therefore, when the disc suction unit 16 descends, as shown in FIG. 4, the two suction pads come into contact with the disc CD before the other one, and suction is started.

When the disk suction unit 16 further descends, the two preceding suction pads 23 are pressed downward by the spring 24. As a result, one side of the disc CD is pushed downward and the other side floats up as shown in FIG. The other suction pad comes into contact with the lifted disc CD, and the suction is completed.

As the other side of the disc CD floats in this way, a gap 25 is formed between the first and second discs CD, and the two discs CD do not come into close contact with each other. Therefore, when the disc suction unit 16 moves up, only the uppermost disc is sucked and taken out. As described above, the disc suction unit 16 not only can take out the discs CD without scratches, but also has the function of preventing the two discs from being taken out.

The static elimination air nozzle 21 will be described. When the disc suction unit 16 takes out the disc CD, the static elimination air nozzle 21 blows high-pressure air into the gap 25 in FIG. 5 and forcibly peels the two discs CD by air pressure. As a result, it is possible to more reliably prevent the double picking. The static elimination air nozzle 21 is attached to the disc suction unit 16 and blows the static elimination air toward the vicinity of the tip of the suction pad 23. Since the nozzle 21 is attached to the disc suction unit 16, the static elimination air is always directed toward the vicinity of the first and second discs from the top regardless of the number of discs CD mounted on the disc holder 12. Can be sprayed.

Further, in this embodiment, static elimination air is used as the high pressure air. This is a function to forcibly peel off the two discs CD by air pressure, and at the same time, to remove the static electricity when the disk CD is charged with static electricity and to eliminate the attraction force between the disks due to static electricity. I do. As a result, it is possible to further reliably prevent the two sheets from being taken.

The static elimination air nozzle 21 may blow static elimination air to the disc CD when the disc suction unit 16 moves to the tray holding portion 18 to separate the disc CD. In this way, the static electricity generated during the transportation of the disc CD is removed from the disc, so that it is less likely that foreign matter will be attracted when the tray is taken out from the disc automatic feeder 1. The static elimination air nozzle 21 may always be operated during the operation of the automatic disk feeder 1.

Next, the two-disc removal prevention unit 22 will be described. The two-disk removal prevention unit 22 shown in FIG. 3 is in the retracted position. During operation, the two-disk removal prevention unit 22 falls in the direction shown by the arrow in FIG. 3 to the state shown in FIG. The two-disk removal prevention unit 22 has a plastic belt 26 attached to its tip. The belt 26 has a roughened surface to increase friction resistance. And its surface is directed to the disc CD. The belt 26 is provided at a position in contact with the end surface of the disc CD when the suction pad 23 attracts the disc CD and moves up.

Now, as shown in FIG. 6, a case where two discs CD are adhering to the adsorbing pad 23 and ascending while being in close contact will be described with reference to FIG. The belt 26 first comes into contact with the end surface of the upper disc as shown in FIG. 7A as the disc CD moves upward. When the disc CD further rises, the belt 26 simultaneously contacts the end faces of both discs, as shown in FIG. 7B. When the disc CD further rises, the belt 26 contacts only the end face of the lower disc.

During this time, due to the notch on the surface of the belt 26, the disc CD in contact with the belt 26 receives a resistance force against rising. However, since the upper disk is sucked by the suction pad 23, it does not fall in any of the cases of FIGS. 7 (a) and 7 (b). However, since the lower disc is simply attached to the upper disc by static electricity or some other force, when the state of FIG. 7C is reached, the upper disc is affected by the resistance force of the surface of the belt 26. It is peeled off and falls. The falling disc returns to its original position when guided by the central shaft 13 of the disc holder 12.

Although the embodiments of the present invention have been described above, the present invention is not limited to the above embodiments. For example, if all of the static elimination air nozzles 21 or the two-disc removal prevention unit 22 are provided, the two-disc removal prevention will be reliable. However, as is clear from the description of FIGS. 4 and 5, the disk suction unit 16 itself also has the function of preventing the removal of two discs, so the static elimination air nozzle 21 and the disc two-disc removal prevention unit 22 are omitted. It is also possible.

Further, the static elimination air nozzle 21 or the two-disk removal prevention unit 22 can be individually attached. Further, as described above, the static elimination air nozzle 21 may be a high pressure air nozzle.
