Abstract

PURPOSE:To safely keep disks in custody and, at the same time, to easily handle the disks, by forming spacers in such a way that each spacer is provided with a recessed and projecting parts, by which the spacers can be laminate by putting the projected part of one spacer in the recessed part of another and can prevent a disk and a guide body from being allowed to contact with each other. CONSTITUTION:A spacer 2 is put on a guide body 4 by passing the guide body 4 through the center hole 20 of the spacer 2 and a base plate 3, in which the guide body 4 is planted, is caused to support the spacer 2. Then a disk 1 is superposed with the spacer 2 by passing the projecting part 21 of the spacer 2 through the center hole 10 of the disk 1. Then another spacer is put on the disk 1 in the same way. In this way, the spacers 2 and disks 1 are alternately laminated to the necessary number of layers. Thus disk stacking is performed. When this disk stacking device is used, the contact of one disk 1 with the guide body 4 or another disk 1 is prevented and the weights of the disks are successively supported by the spacers 2 and, finally, by the base plate 3. Therefore, no load is applied to any disks 1.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a device for stacking and storing discs in storage, storage, transportation, or manufacturing, and particularly relates to a disc substrate or recording device that can be used for information recording, etc. The present invention relates to a disk stacking device.

[Background technology and its problems]

2. Description of the Related Art Disks such as optical disks and magnetic disks as recording media used for recording information are generally stacked in layers during storage, storage, transportation, or manufacturing. At this time, the recording surfaces, which are the most important parts of the disk, may come into contact with each other, causing damage to the surface and making it unusable as a recording substrate, or the recorded contents may be lost or the disk may become unusable. ,
It was necessary to prevent this.

For this reason, conventionally, as shown in FIG. 6, the disk 6 and the spacer 8 having a center hole 80 that can be inserted into the guide body 7 are alternately inserted into the guide body 7 that can be inserted into the center hole 60 of the disk 6. The disks 6 were inserted into and stacked to prevent the disks 6 from coming into contact with each other.

However, when such a disk 6 is inserted, the center hole 60 may be damaged, or when a large number of disks 6 are stacked, a large load is applied to the disk 6 at the lower position, and the portion in pressure contact with the spacer 8 may be damaged. There is a danger.

Moreover, since it is impossible to directly take out a specific disk from among the disks 6 stacked in this way, the disks 6 and spacers 8 stacked above the specific disk 6 are sequentially removed from the guide body 7. Requires work. At this time, it is difficult to maintain the stacking of the removed disks 6 and spacers 8 without assistance such as inserting them into another guide 7, etc., and they easily crumble and scatter due to a slight external force, making them difficult to handle. In addition to being extremely difficult, there was also the problem that there was a risk of damaging the recording surface.

The above problem is a factor that reduces productivity during sampling inspections and subsequent processing steps, especially in the production of optical disk substrates using injection molding machines.In addition to hindering quality maintenance, it also becomes an obstacle to automation of the manufacturing process. Therefore, it has been desired to develop a new disk stacking device.

[Purpose of the invention]

The purpose of the present invention is to:
To provide a disk stacking device that can safely protect disks and is easy to handle.

[Means and effects for solving the problem] The present invention provides spacers that are alternately interposed between a plurality of stacked disks to prevent the disks from coming into contact with each other;
The spacers of the disk stacking device are equipped with a guide body capable of guiding these spacers in the stacking direction, and each spacer has a concave and convex portion that can be fitted to each other, so that the spacers can be fitted together and stacked in a columnar shape. , and is interposed between the disc and the main body to prevent contact between them.

In the present invention configured as described above, the stacking of disks during normal storage is guided by a guide body that passes through the spacer in the stacking direction, and the stacking is prevented from being disturbed. Further, since the spacer is interposed between the disk and the guide body and prevents them from coming into contact with each other, damage and contamination of the disk can be avoided. Furthermore, even when the disks stacked above and the spacer are taken out individually or all at once, such as when taking out a specific disk from a stack of disks, even when stacked without a guide, the irregularities of the spacer By fitting the layers together, it is possible to prevent the laminated layers from easily collapsing and scattering, and to facilitate handling.The present invention aims to achieve the above object as described above.

〔Example〕

An embodiment of the present invention will be described with reference to FIGS. 1 and 2.

In FIG. 1, disks 1 and spacers 2 are stacked alternately, and the center hole 20 of the spacer 2
A cylindrical or cylindrical guide body 4 with an outer diameter of 9,951 mm is inserted upright from the bottom plate 3 .

The disk 1 is a magnetic disk that has a center hole 10 and is often used for recording information by coating a magnetic material on a metal or resin substrate, or a digital audio disk or a video disk that has a substrate made of polycarbonate or polymethyl methacrylate. , an optical disk used as a memory disk, etc., but here the inner diameter is 15 mm.
Outer diameter 1 made of polycarbonate with a central hole 10 mm
20mm.

It is in the shape of a disk with a thickness of 1.211111 mm.

The spacer 2 is made of a resin that is relatively soft and has a smooth surface so as not to easily damage the disk 1, and is preferably made of polytetrafluoroethylene (trade name: Teflon), for example.

In Fig. 2, the spacer 2 has a disk shape with an outer diameter of 30 m + * and a thickness of 3 -, and the outer diameter of the spacer 2 is 1.
4.9 mm and height 1-1, a convex portion 21 that can be inserted into the center hole 10 of the disk 1 is provided, and on the back side of the convex portion 21 there is another spacer 2 into which the disk l is inserted.
A recess 2 with an inner diameter of 14 and 95 mm into which the protrusion 21 of the
2 is provided. Furthermore, these concave portions 22 and convex portions 2
1 penetrates the front and back sides of the spacer 2, and the guide body 4
A center hole 20 with an inner diameter of 10.05 mm is provided through which the holder can be inserted.

In such a configuration, stacking of the disks 1 is performed as follows.

First, the guide body 4 is inserted through the center hole 20 of the spacer 2,
The spacer 2 is supported on the bottom plate 3 on which the guide body 3 is erected.Next, the guide body 4 is inserted through the central hole 10 of the disk 1, and is fitted into the convex portion 21 of the spacer 2. Furthermore, another spacer 22 is inserted through the guide body 4, and this spacer 2
The concave portion 22 of the spacer is fitted into the convex portion 21, and another disk 1 is fitted into the convex portion 21 of the spacer.

In this way, the spacers 2 and the disks 1 are stacked alternately and stacked in the required number of stages to perform stacking.

At this time, the disk 1 is held between the spacers 2 and prevented from coming into contact with the guide body 4 or other disks 1,
Furthermore, the stacked disks 1 and spacers 2 are connected to the guide body 3.
This prevents the lamination from collapsing or becoming disordered. Further, since the weight of the disk 1 and the spacer 2 is sequentially supported by the spacer 2 and received by the bottom plate 3, no load is applied to the disk 1.

Here, even if a specific one of the stacked disks 1 is taken out and the spacers 2 and disks 1 are alternately stacked without the guide 4, the convex portions 21 and the concave portions 22 will not fit together. This prevents the lamination from easily collapsing or becoming disordered, and also prevents the disks 1 from coming into contact with each other and from applying a load to the disks 1.

As described above, according to this embodiment, by interposing the spacers 2 alternately when stacking a plurality of disks 1, contact between the disks 1 and contact between the disks 1 and the guide body 4 is prevented. can. In addition, the weight of the disk 1 and spacer 2 stacked above is supported by the spacer 2,
Since a load is prevented from being applied to the disk 1, there is an effect that the disk 1 can be prevented from being damaged and can be safely protected.

In addition, when the disks 1 and spacers 2 of this embodiment are stacked alternately on the guide body 4, it can be prevented from collapsing or being disturbed by the guide body 4.
When stacked on a desk ring without the guide body 4 during loading and unloading operations, the fitting between the convex portion 21 and the concave portion 22 of the spacer 2 prevents it from collapsing or becoming disordered, making it easy to handle. This has the effect of improving work efficiency.

According to experiments, 50 discs 1 of the present embodiment were
were stacked on the guide body 4 using the spacer 2, and then the upper 25 sheets were extracted from the main body 4 and stacked on a table.
These 25 disks maintained a stable stack and could withstand movement sufficiently. In the above embodiment, the guide body 4 was cylindrical, but it may be cylindrical or square. The spacer 2 may have a columnar shape, in which case the center hole 20 of the spacer 2 may have a rectangular shape that can be inserted into the prism, and the convex portion 21 and the concave portion 22 of the spacer 2 may have a tapered shape that can be fitted into each other. It is possible to improve work efficiency by making it easier to fit the time. Furthermore, the materials and dimensions of the disk 1 and the spacer 2 are not limited to those in the embodiment described above (but may be selected as appropriate).

On the other hand, as another embodiment of the present invention, a spacer 5 as shown in FIGS. 3 to 5 is used, and three rod-shaped guide bodies 4 are used.
The disc 1 may be stacked on a bottom plate 30 with a
In such an embodiment, the spacer 5 has a substantially triangular shape, has tip portions 53 at three ends, and has a fifth end.
As shown in cross section in the figure, this tip portion 53 is formed with a convex portion 51 and a concave portion 52 that can be fitted into each other on the front and back sides, and an internal groove 50 through which the guide body 40 can be inserted. Such a spacer 5 can be stacked in a columnar manner by fitting the convex portion 51 and the concave portion 52, and can be stacked alternately with the disks 1 and guided by the guide body 40 and stacked on the bottom plate 30, and It is possible to stack them on a desk or the like without the guide body 40.

According to such an embodiment, in addition to having the same effect as the above-mentioned embodiment, it is possible to move the disc 1 by holding the tip portion 53 when removing it, so that it is possible to remove the disc 1 from a thin or weak disc. This is especially effective when you want to avoid stains on your hands or other materials. In addition, since it does not affect the center hole 10 of the disk l at all, it can be used even for disks that do not have a center hole 10 or are very small.If you particularly want to avoid damage to the center hole 10, you can prevent that damage in advance. There is also the effect that it can be done. Note that a cushion material may be attached to the surface of the spacer 5 that comes into contact with the disk I, if necessary, to prevent play and prevent the disk 1 from being exposed to external vibrations while stacked. can be stopped from moving to prevent damage caused by friction.

It should be noted that the present invention is not limited to the above two embodiments, but in short, the guide bodies 4. 40, the spacers 2.5 are guided in the stacking direction, and each spacer 2.5 is provided with a convex portion 21.51 and a concave portion 22.52 that can be fitted into each other, and these are fitted into each other. A plurality of discs can be stacked in a columnar manner, and the discs can be interposed between the disc and the guide to prevent contact between them.
