Description

Detailed Description of the Invention [Field of Industrial Application] The present invention relates to a device for stacking and storing disks in storage, storage, transportation, or manufacturing, and particularly relates to a disk substrate or a 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, which are 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. can be,
It was necessary to prevent this.

For this reason, conventionally, as shown in FIG.
and spacers 8 having
The disks 6 were prevented 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 that presses against the spacer 8 may be damaged. There is a danger.

Furthermore, 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 lamination of the removed disk 6 and spacer 8 without assistance such as inserting them into another guide 7, etc., and they easily collapse and scatter due to a slight external force. In addition to being extremely difficult to handle, there were also problems with the possibility 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 was desired to develop a new disk stacking device.

[Purpose of the invention]

An object of the present invention is to provide a disk stacking device that can safely protect disks during storage, storage, transportation, or manufacturing and is easy to handle.

[Means and actions for solving problems]

The present invention includes a plurality of guide bodies arranged in a circumferential direction outside the disks to be stacked and extending in the stacking direction, and a plurality of tip portions capable of holding the disks and formed outside the disks. and a spacer that is engaged and guided by the spacer, and a plurality of spacers can be stacked in a columnar shape by being connected only through the tips, and when the spacers are stacked on each tip, the spacers are connected only through the tips. It is characterized in that a concave portion and a convex portion are formed that can be mutually fitted with the spacer.

In the present invention configured as described above, by stacking the disks and spacers alternately with the tips located outside the disks during normal storage, the disks are prevented from coming into contact with each other. Be safe and protected.

At this time, each spacer is engaged with and guided by a guide body at the sidewardly protruding tip end of the stacked disks, thereby preventing the stacking from being disturbed. Also,
Since the tip of the spacer is interposed between the disk and the guide and does not bring them into contact, damage to the disk is avoided.

Further, when taking out a specific disk from a stack of disks, by holding the tip end protruding from the outer periphery of the disk, contamination of the disk can be more reliably prevented.

Then, even when the disk to be taken out and other disks and spacers stacked above the spacer are taken out individually or all at once and stacked without a guide, by fitting the uneven parts of the spacers, It is possible to prevent the stack from easily collapsing and scattering, and the handling becomes easy.

The present invention aims to achieve the above object.

[Example] An example of the present invention will be described with reference to FIGS. 1 and 3.

As shown in Figure 1, disk 1 and spacer 5
are vertically stacked on top of each other in a substantially horizontal manner on the bottom plate 30, and are held inside three rod-shaped guide bodies 40 vertically erected on the bottom plate 30.

The disk 1 is a magnetic disk that is often used for recording information by coating a magnetic material on a metal or resin substrate, or a magnetic disk that has a substrate made of polycarbonate or polymethyl methacrylate and is used as a digital audio disk, video disk, or memory disk. For example, it is a polycarbonate optical disc with an outer diameter of 120 mm and a thickness of 1.2 mm, and has a center hole 10 with an inner diameter of 15 mm.

The spacer 5 is made of a relatively soft resin with a smooth surface so as not to easily damage the disk 1, and is preferably made of polytetrafluoroethylene (trade name: Teflon), for example.

As shown in FIG. 2, the spacer 5 has a substantially triangular planar shape with each side curved inward, and each of the three tips extending outward from the outer periphery of the disk 1 has a block-shaped tip 53. is formed.

The inner surface of each tip portion 53 is a curved surface along the outer periphery of the disk 1, and the height from the central approximately triangular plate-shaped body portion is greater than the thickness of the disk 1. Even if another spacer 5 is stacked with the disk 1 placed and held on the disk 1, the held disk 1 is set so as not to come into contact with the stacked other spacer 5.

As shown in FIG. 3, each tip 53 is formed with a notch-shaped guide groove 50 that extends from the outer surface to the inside and passes through the upper and lower surfaces. By aligning them, the plurality of spacers 5 are guided in the same position and direction, and the desired stacked state on the bottom plate 30 is maintained.

Furthermore, a convex portion 51 and a concave portion 52 that can be fitted into each other are formed on the upper and lower surfaces of each tip portion 53, and when the spacers 5 are stacked, these convex portions 51 and concave portions 52 fit together, Even when placed on a desk or the like and not guided by the guide body 40, the stacked state can be maintained.

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

First, the disk 1 is attached to the bottom plate 3 having the guide body 40.
When stacking at 0, place and hold the disk 1 on the flat part inside the tip 53 of the spacer 5,
This spacer 5 is held directly above the guide body 40, the guide grooves 50 of each tip portion 53 are engaged with the guide body 40, and the spacer 5 is guided along the guide body 40 and lowered.
It is placed on the bottom plate 30.

Next, another spacer 5 holding the disk 1 in the same manner is engaged and guided by the guide body 40, placed on top of the previously placed spacer 5, and placed on top of the previously placed spacer 5.
The convex portion 51 of the spacer 5 and the concave portion 5 of the newly lowered spacer 5
These spacers 5 are overlapped by engaging the spacers 2 and 2 in a concave and convex manner.

By following the same procedure, spacers 5 holding other disks 1 are stacked up to the required number of stages, so that the spacers 5 holding disks 1 are stacked on the bottom plate 30, and the disks 1 and spacers 5 are stacked on top of each other.
are stacked and stacked alternately.

On the other hand, when taking out any one of the disks 1 stacked in this way, grasp the tip portion 53 of the stacked spacers 5, take it out along the guide body 40, and place it one after another on a nearby desk or the like. The convex portions 51 and the concave portions 52 are stacked in a state in which they are engaged with each other.

Then, when the spacer 5 holding the required disk 1 comes out, that disk 1 is taken out from the spacer 5.

According to this embodiment, by interposing the spacers 5 alternately when stacking a plurality of disks 1, the disks 1 are brought into contact with each other and the disks 1
Contact with the guide body 40 etc. can be prevented. In addition, the weight of the disk 1 and spacer 5 stacked above is supported by the tip 53 of the spacer 5, and the load is prevented from being applied to the disk 1, so damage to the disk 1 can be prevented. It has the effect of providing safe protection.

In addition, when the disks 1 and spacers 5 of this embodiment are stacked alternately, the guide body 40 prevents them from collapsing or being disturbed when they are stacked on the bottom plate 30. Even when stacked on a desk etc. without the guide body 40,
The fitting between the convex portion 51 and the concave portion 52 of the spacer 5 prevents the stacking state from collapsing or becoming disordered.
Since it is easy to handle, it has the effect of improving workability.

According to the experiment, according to this embodiment, 50 discs 1 were stacked on the guide body 40 using the spacer 5, and then the upper 25 discs were taken out from the guide body 40 and stacked on a table. The disk maintained a stable stack and was sufficiently durable to be moved.

Furthermore, when taking out, etc., the tip portion 53
Since it is possible to move the disk by holding it, it is possible to prevent contamination caused by directly holding the disk 1, etc., and also to avoid the risk of damage if the disk 1 is thin or made of weak material, and to protect it. It is particularly effective from this point of view.

In addition, since it does not affect the center hole 10 of the disk 1 at all, it can be used even for disks that do not have a center hole 10 or are very small, and if you particularly want to avoid damage to the center hole 10, you can prevent that damage from occurring. It also has the effect of preventing it.

In the above embodiment, the guide body 40 is rod-shaped, but it may also be shaped like a prism.In short, the guide body 40 is engaged with the tip end 53 of the spacer 5 so that the guide body 40 can be guided in the stacking direction. That's what it means.

Further, the convex portion 51 and the concave portion 52 of the spacer 5 may have a tapered shape that allows them to fit into each other. In this way, fitting during stacking becomes easier and work efficiency can be improved.

Further, the materials and dimensions of the disk 1, spacer 5, etc. are not limited to those in the embodiments described above, but may be selected as appropriate.

In addition, a cushioning material may be attached to the surface of the spacer 5 that comes into contact with the disk 1, if necessary, to prevent play and cause the disk 1 to move when subjected to external vibrations while stacked. This can prevent damage caused by friction.

〔Effect of the invention〕

As described above, the disk stacking device of the present invention has the advantage that disks can be safely stored and easily handled during storage, storage, transportation, or manufacturing.
