[Problems to be Solved by the Invention]

 According to the above conventional technique, there are some problems in the following points. First, in the above-mentioned primary cooling device, the holding device of the primary cooling device 1 holds the above-mentioned disk of relatively high temperature horizontally, and at this time, the above-mentioned clan is fitted with a pin in the center hole. Since it supports only the ping area, there is a problem that the shape of the center hole is changed first, and secondly, the outer peripheral edge of the disk hangs down. Next, since the holding device of the primary cooling device of 2 above holds the disk of relatively high temperature horizontally, at this time, it supports the outer peripheral ends of the one side and the other side disk substrates. , Firstly, the central part of the disc hangs down, secondly, the outer peripheral edge of the disc is damaged, and thirdly, a relatively large flat area is required when the discs are arranged horizontally. There was a problem.

Next, according to the secondary cooling device, since the one-side and the other-side disk substrates are stacked and held, there is no space between the disk substrates. As a result, firstly, each disk substrate comes into contact with each other, and it is easy to scratch both the front and back surfaces of the disk substrate. Secondly, there is a surface that the cooling air sent to the inside of the secondary cooling device does not hit, so it is difficult to apply the cooling air to the Dick substrate evenly, and the cooling time tends to be long. there were. Further, since the secondary cooling device was controlled so as to send both the one side and the other side disk substrates to the next device at the same time, both the one side and the other side disk substrates were mixed. It was sent to the next device. Therefore, even if there is an apparatus that later identifies and sorts the mixed one-side and other-side disks, the above-mentioned identification and sorting of the mixed one-side and other-side disk substrates may not be performed reliably. Was increasing.

Next, according to the positioning device, although there are the above-mentioned purposes, conventionally, there is no means for satisfying these purposes, and a specific means for satisfying the above-mentioned purposes has been demanded.

Therefore, an object of the present invention is to prevent the disk substrate from changing its shape or being damaged when the disk substrate is held in the primary cooling device as 1. It is possible to hold a large number of disk substrates with a relatively small plane occupying area, and as a result, it is difficult for the secondary cooling device to scratch the disk substrates, and the cooling air can easily hit the cooling air evenly. The cooling time is short, and further, this identification and sorting can be performed surely in the work after the identification and sorting of the disk substrates on the one side and the other side. If the disk substrate can be placed in the next device in 1 without touching the glued surface, and the conveyor belt is used in 2 as the device for transporting the glued one side and the other side discs. In this case, there is no risk of slip marks or scratches on the transparent surface, which is the back side of the glued surface of the disc, caused by the conveyor belt. Another object of the present invention is to provide a means capable of accurately positioning the one-side and the other-side disks when the one-side and the other-side disks are arranged in the apparatus for pressing together, in order to bond the one-side and the other-side disk substrates.

[Action]

 According to the one-side primary cooling device 120A, since the one-side disk substrate 2A is held in the vertical posture, the shape does not change. More specifically, by holding the one-side disk substrate 2A in a vertical state, the sagging hardly occurs and the shape does not change. Further, according to the suction device 123, only the clamping area 6 of each of the one side and the other side disks 2A and 2B is sucked and held by vacuum suction, so that the disk substrate is not scratched. Further, since the disc substrate is held vertically, the plane area occupied by the disc substrate is small.

According to the secondary cooling device, the holding device 142 holds each of the plurality of one-side and other-side disk substrates 2A, 2B independently. In addition, the holding state of the one side and the other side disk substrates 2A, 2B is in a vertically standing state, and the receiving piece 150 allows the end surface of the one side disk substrate 2A to have a relatively small arc range. The contact pieces 150 are brought into contact with each other. Further, the cooling air passage hole 142c is formed between the receiving pieces 150. By holding the one-side and the other-side disk substrates 2A and 2B in the holding device 142 in this way, when the cooling air 145 is applied from the lower part of the holding device 142, the one-side and the other-side disk substrates 2A. The cooling air 145 is evenly applied to each of 2B. As a result, it is easy to cool the above-mentioned one-side and other-side disk substrates 2A, 2B in a short time. Further, since the receiving piece 150 receives the one-side and the other-side disk substrates 2A within a relatively small arc range, the one-side and the other-side disk substrates 2A are not easily scratched.

Further, according to the secondary cooling device, while the one-side disk substrate 2A is being transported from the one-side secondary cooling device 140A to the downstream device, the other-side secondary cooling device 140B is provided with the other components. When a predetermined number of side disk substrates 2B are stored and the one side secondary cooling device 140A has finished carrying one side disk substrate 2A, the other side disk substrate 2B is started to be transferred to a downstream device. During this period, the one-side secondary cooling device 140A is provided with a control device that stores a certain number of the one-side disk substrates 2A and then repeats this operation. This identification and sorting can be ensured in the work after the identification and sorting.

According to the one-side and the other-side positioning devices 520A and 520B, the one-side and the other-side disks from the device for conveying the glued one-side and the other-side disks are directly placed in the one-side and the other-side disk positions. It can be passed through the disk passage opening 521 of the ejecting device 520A, 520B and placed in the next device. At this time, the one-side and the other-side disks 3A, 3B fall with the gluing surface facing upward, so that the gluing surface does not come into contact with any part. When a conveyor belt is used as a device for transporting the glued one side and the other side disks 3A, 3B, the one side and the other side disks 3A, 3B are continuously connected to each other without stopping the conveyor belt. It can be supplied to each of the side and other side disk positioning devices 520A, 520B. As a result, slip marks, scratches, etc. on the conveyor belt are not attached to the transparent surface, which is the back surface of the glued one side and the other side disks 3A, 3B. In addition, no other transport device is required for the above delivery. In addition, since there is no contact with the other transport device members on the glued surface and the rear transparent surface of the disk, scratches and the like do not occur. Further, the transfer to the next device always passes through the disc passage opening portion, so that the one side and the other side discs can be accurately arranged in the next device located thereunder.

【Example】

 Next, embodiments of the present invention will be described in detail with reference to the accompanying drawings. The apparatus shown in FIGS. 1 and 2 is a manufacturing apparatus of the optical information recording medium of the present invention, the apparatus shown in FIG. 1 is the manufacturing apparatus of the previous step, and the apparatus shown in FIG. It is a manufacturing device for the process. That is, the present apparatus is an optical information recording medium manufacturing apparatus in which the one-side disc 3A and the other-side disc 3B are molded and the two discs are bonded together. The present invention is a 1.2 mm optical information recording medium manufacturing apparatus in which a one-side disc 3A having a thickness of 0.6 mm and another side disc 3B having a thickness of 0.6 mm are bonded together.

First, the configuration of the manufacturing apparatus in the preceding step will be described with reference to FIGS. 1 and 3 to 13. FIGS. 3 to 13 are partial detailed views of each device schematically shown in FIG. This pre-process manufacturing apparatus includes an apparatus for molding and transporting the one-side disk substrate 2A, an apparatus for molding and transporting the other-side disk substrate 2B, and a metal reflection film on the one-side disk substrate 2A and the other-side disk substrate 2B. It is composed of a group of devices divided into three regions, that is, a device for forming and transporting the layer and the protective film layer.

An apparatus for molding and carrying the one-sided disc substrate 2A will be described below. This device includes a one-side molding machine 110A, a one-side primary cooling device 120A, a one-side adsorption transport device 130A, a one-side secondary cooling device 140A, and a one-side transfer device 160A.

The one-side molding machine 110A is a device for molding the one-side disk substrate 2A. The one-sided disc substrate 2A is a plastic substrate in which pits corresponding to information recording signals are recorded on a disc original plate formed of a resin material such as polycarbonate or acrylic.

Next, the one-side primary cooling device 120A is a device for discharging the one-side disk substrate 2A molded by the one-side molding machine 110A from the inside of the one-side molding machine 110A to perform static elimination, dust removal, and cooling. Is. Specifically, inside the cooling tank 121, there is a holding device 122 that holds the one-side disk substrate 2A. The holding device 122 has a vertically-shaped disc shape, and the one side disk substrate 2A is held along the circumference on the front side of the holding device 122. At this time, the surface of the holding device 122 and the surface of the one-side disk substrate 2A are parallel to each other. That is, the one-side disk substrate 2A is vertically held by the holding device 122 (see FIGS. 1 and 3).

The holding device 122 holds the one-side disk substrate 2A by vacuum suction. In this example, the holding device 122 can hold 10 one-sided disk substrates 2A. For this purpose, the holding device 122 is equipped with ten suction devices 123 on the surface circumference. Further, the one-side primary cooling device 120A includes a static eliminator and a dust remover.

Eight one-sided disk substrates 2A are constantly held and cooled in the inside of the one-sided primary cooling device 120A. Then, one sheet is carried out to a one-side secondary cooling device 140A described later at regular time intervals, and the remaining one sheet is carried out from the one-side molding machine 110A at regular time intervals and held. That is, the one-side primary cooling device 120A is supplied with one one-side disk substrate 2A from the one-side molding machine 110A at regular intervals. At this time, the temperature of the one side disk substrate 2A is about 90 ° C to 120 ° C. The one-sided disk substrate 2A supplied to the one-side primary cooling device 120A is rotated about the central axis of the holding device 122 while being held by the holding device 122. At this time, the temperature of the one side disk substrate 2A is cooled to 60 ° C. by the cooling air introduced into the one side primary cooling device 120A. Then, the one-side disk substrate 2A rotated by a certain angle is carried out to the one-side secondary cooling device 140A described later.

According to the one-side primary cooling device 120A, since the one-side disk substrate 2A is held in the vertical posture, the shape does not change. More specifically, the temperature of the one-sided disk substrate 2A is 90 ° C to 120 ° C immediately after the one-sided disk substrate 2A is molded by the one-sided molding machine 110A and carried out from the one-side molding machine 110A. Very expensive. Therefore, when the one-sided disc substrate 2A is held in a horizontal state, for example, the disc itself may gradually hang down from the peripheral edge of the disc. Therefore, by holding the one-side disk substrate 2A in the vertical state, the sagging is unlikely to occur and the shape does not change.

Next, attention is paid to the suction device 123 included in the holding device 122. 4 and 5, the suction device 123 includes a vacuum pad 123a. The vacuum pad 123a has three suction holes 123C connected to the three suction passages 123b. The suction holes 123C are open to the suction surface 123d of the vacuum pad 123a. The suction surface 123d is a surface that comes into contact with the surface of the clamping area 6 that defines the center hole 4 of the one side disk substrate 2A.

That is, when the suction device 123 sucks and holds the one-side disk substrate 2A, the suction surface 123d of the vacuum pad 123a faces the surface of the suction area portion 6 of the one-side disk substrate 2A. Further, in FIG. 4, a portion where the three suction holes 123c face the clamping area 6 of the one side disk substrate 2A is shown by a one-dot chain line F 1.

According to the suction device 123, the suction surface 123 d of the vacuum pad 123 a is sucked on the surface of the clamping area 6 of the one-sided disk substrate 2 A, so that the center of the one-sided disk substrate 2 A is The hole 4, the clamping area 6 or the outer periphery of the one side disk substrate 2A is not scratched. Moreover, by molding the vacuum pad 123a from a material such as rubber, heat from the adsorption device 123 is hard to be transferred to the one-side disk substrate 2A, and the one-side disk substrate 2A is cooled uniformly. easy. Further, the temperature of the one side disk substrate 2A can be cooled to a predetermined temperature (up to 60 ° C. in this example) at an early stage.

Next, the one-side suction transfer device 130A will be described. The one-side adsorption transport device 130A is a device for transporting the one-side disk substrate 2A from the one-side primary cooling device 120A to the one-side secondary cooling device 140A. Referring to FIG. 1, an arm 132 that rotates about a rotary shaft 131 is provided, and a suction device 133 is attached to an end portion of the arm 132. Then, the adsorption device 133 adsorbs and holds the one-side disk substrate 2A held inside the one-side primary cooling device 120A. Then, the arm 132 is rotated around the rotation shaft 131. The one side secondary cooling device 140A is located at the rotation destination of the arm 132, and the one side disk substrate 2A is housed inside the one side secondary cooling device 140A.

The adsorption device 133 will be described with reference to FIGS. 6 and 7. The adsorption device 133 includes three vacuum pads 133a. Each of the vacuum pads 133a has three suction holes 133C connected to the suction passage 133b. The suction holes 133C are opened on the suction surfaces 133d of the vacuum pads 133a. The suction surface 133d is a surface that comes into contact with the surface of the clamping area 6 that defines the center hole 4 of the one side disk substrate 2A.

That is, when the suction device 133 sucks and holds the one-side disk substrate 2A, the suction surface 133d of the vacuum pad 133a faces the surface of the suction area 6 of the one-side disk substrate 2A.

Next, the one-side secondary cooling device 140A will be described with reference to FIGS. 8 to 12. The one-side secondary cooling device 140A further cools the one-side disk substrate 2A cooled to 60 ° C. by the one-side primary cooling device 120A to a further 40 ° C. temperature and temporarily holds the disk buffer. It is a device used as.

The one-side secondary cooling device 140 A is provided with a holding device 142 for holding the one-side disk substrate 2 A inside the cooling tank 141. The holding device 142 is axially supported from below on an output shaft 144 that is rotated by a motor 143. Further, in the cooling tank 141, a pipe for guiding the cooling air 145 is connected to the inside of the cooling tank 141. This pipe is a cooling air guiding pipe 147 connected to the bottom portion 141a of the cooling tank 141, and an opening 147a of the cooling air guiding pipe 147 is located below the holding device 142. A fan 148 is provided as a means for forcibly guiding the cooling air 145 introduced into the cooling tank 141 to the holding device 142.

That is, by the rotation of the fan 148, the cooling air 145 introduced from the bottom portion 141 a of the cooling tank 141 hits the holding device 142 from below. Then, the cooling air 145 that has passed through the holding device 142 is discharged to the outside of the cooling tank 141 from the suction duct 146 connected to the upper portion 141b of the cooling tank 141. The temperature of the cooling air 145 introduced into the cooling tank 141 is 0 ° C to 10 ° C. Further, a static elimination bar-151 is arranged below the holding device 142. The static eliminator bar 151 is means for preventing static electricity from charging the one side disk substrate 2A held by the holding device 142 and the holding device 142.

Next, attention is paid to the holding device 142. The holding device 142 has a circular shape when seen in a plan view, has a thickness T along the vertical direction Z, and is positioned horizontally. In order to hold the one-side disk substrate 2A, a plurality of one-side disk substrate accommodating portions 142a are formed by dividing the above-mentioned holding device 142 into equal parts when seen in a plan view.

Of the plurality of one-side disk substrate housing portions 142a, adjacent one-side disk substrate housing portions 142a are partitioned by partition walls 142b. The one side disk substrate housing portion 142a is formed by arranging three receiving pieces 150 side by side in the radial direction of the holding device 142 when seen in a plan view. The three receiving pieces 150 are portions that receive the one-side disk substrate 2A.

The cooling air passage hole 142c is opened in the upper space 142d and the lower space 142e located above the holding device 142.

The three receiving pieces 150 have the same shape. Focusing on one of them, the cross section is formed in an M shape, and the valley portion 150a which is an open portion has the one side disk substrate. The opening angle R is large enough to hold 2A (see FIG. 10). The outer peripheral edge portion 7 of the one-side disk substrate 2A is in contact with the valley portion 150a.

Then, one one-side disk substrate 2 A is positioned over the three receiving pieces 150. That is, the one-side disk substrate 2A is held on the holding device 142 by the three receiving pieces 150. At this time, the one side disk substrate 2A is positioned in a standing state so that the surface of the one side disk substrate 2A is vertical.

A cover 142h is attached.

Then, the holding device 142 is rotated counterclockwise by the motor 143 when viewed from a plane. The holding device 142 cools the one-side disk substrate 2A for about 4 minutes while being rotated from the input port 142f to the discharge port 142g.

According to the one-sided secondary cooling device 140A, each of the plurality of one-sided disk substrates 2A is independently sectioned and held by the holding device 142. Further, the holding state of the one-sided disk substrate 2A is in a state of standing upright, and the receiving piece 150 allows the receiving piece 150 within a relatively small arc range on the end face of the one-side disk substrate 2A. Are in contact with each other. Further, the cooling air passage hole 142c is formed between the receiving pieces 150. By thus holding the one-side disk substrate 2A in the holding device 142, when the cooling air 145 is applied from the lower part of the holding device 142, the cooling air 145 is evenly distributed to each of the one-side disk substrates 2A. Hit This facilitates efficient cooling of each of the one-sided disk substrates 2A. Further, since the receiving piece 150 receives the one-side disk substrate 2A within a relatively small arc range, the one-side disk substrate 2A is not easily scratched.
