Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a light-shielding packaging of a long roll photosensitive material such as color printing paper, a packaging method thereof and a packaging apparatus.

[0002]

2. Description of the Related Art A light-shielding leader is joined to the end of the winding end of a long roll photosensitive material to shield the outer periphery of the roll photosensitive material, and a light-shielding disk-shaped light-shielding sheet is provided on both end faces of the roll photosensitive material. The light-shielding leader and the light-shielding sheet are adhered to each other, and the light-shielding sheet has a right-angled fold portion from the end face of the winding core to the inner peripheral surface of the light-shielding sheet and the contact portion between the inner peripheral surface of the winding core. Is adhered or left folded to form a light-shielding package of roll photosensitive material, which can be loaded into a photosensitive material supply unit such as a printer under bright room light.

[0003] In addition, such a light-shielding package is of a type that does not use the above-mentioned light-shielding sheets on both sides but uses only a wide light-shielding leader and folds up to the inner peripheral surface of the core while forming a fold. There is also.

Regarding these, the actual development of Sho 60-167796
Japanese Patent Laid-Open No. 2-72347, Japanese Patent Laid-Open No. 62-172344, and the like. In the packaging forms disclosed therein, in the overlapping portion of the light-shielding leader and the light-shielding sheet, Slit-shaped notches are radially formed in the widthwise direction of the outer peripheral surface or in the outer peripheral direction of the side end surface in one of the portions bent at right angles. Then, the cut portion is bent at a right angle to bond the light-shielding leader and the light-shielding sheet.

When the above-mentioned notching process is not carried out, instead of it, a pleats are attached and similarly bent and bonded.

In this way, the entry of external light from the outer peripheral surface is prevented.

At the same time, the disc-shaped light-shielding sheet is folded at a right angle from the end face of the winding core to the inner peripheral portion of the winding core. Further, as described above, the disc-shaped light shielding sheet is bonded to the winding core. Some of them have been made, but the folds have radial cuts or pleated folds.

In this way, external light is prevented from entering from the core of the winding core, and the entire roll photosensitive material is shielded from light.

[0009]

As described above, in the packaging form disclosed in the prior art, the light-shielding leader and the disc-shaped light-shielding sheets on both sides are properly joined, or the fold-shaped convolution is properly made. As long as it is possible, the purpose of shading is achieved and the work of mounting the printer in a bright place can be easily performed.

However, since the slit-shaped notch is processed to a position close to the axial width dimension or the outer diameter dimension of the roll photosensitive material, the center deviation between the winding core and the disc-shaped light-shielding sheet. If there is any, there is the invasion of external light, and the instability that fogging of the photosensitive material occurs is also mediated.

[0011] Then, such a cutting process itself is troublesome, which causes a problem of increasing man-hours and decreasing yield.

There is also used a method in which a fold-shaped fold is bent at a right angle to the outer peripheral surface or the end surface of the outer peripheral portion instead of the notch to bond the overlapping portion and the contact portion. When the body is loaded into the supply unit such as a printer and the light-shielding leader is pulled to release the adhesive on the folds, when the leader does not have the folds, the folds are removed. The pleated portions of the light-shielding sheet on both sides of the sheet may cause damage such as scratches by touching the photosensitive material that is being drawn out, and conversely, when the pleated portion is provided on the reader side, Since the width of the light-shielding leader is wide and irregularly wide, the light-shielding leader cannot serve as a conveyance leader.

Further, in order to achieve the light shielding of both the outer peripheral portion and the core core portion with only a wide light-shielding reader, it is also possible to perform a fold-like convolution on the end surface of the roll photosensitive material and the inner peripheral portion of the core core. It is being appreciated. However, such a light-shielding reader can no longer be expected to aim at the reliable safety of conveyance while reading the leading portion of the roll photosensitive material, and the purpose and function of the package will be greatly different.

Further, when the pleated portion is folded into the inner peripheral portion of the winding core, there is a problem that the rotation between the core and the shaft is not smooth.

The present invention solves the above problems, and a roll of a simple package that does not cause damage such as scratches or pressure due to the stable transfer of a light-sensitive material that is completely protected from light and moisture. An object of the present invention is to provide a light-sensitive material, a method of packaging the same and a packaging device.

[0022]

As shown in the perspective view of FIG. 1, a photosensitive material 3 is wound around a winding core 2, a light-shielding reader 5 having the same width is joined to the end of the core, and the winding is further wound. Is sealed by, for example, attaching a sticker label 9 shown in FIG.
Further, as shown in the perspective view of FIG.
An end light-shielding cover 11 having an outer diameter larger than the outer diameter of the scroll is applied to 10A and 10B, a large outer diameter portion is folded back to the outer peripheral surface of the scroll, and the adhesive is applied to the surface of the light-shielding cover. The rolls of the photosensitive material were shielded from each other by using an agent.

Of course, the shading leader and the end shading cover are
As shown in the cross-sectional view of 12 layer structure, it is possible to form a moisture-proof layer structure of an Al thin layer as well as light shielding by a black PE, so that the weather-proof property of a light-sensitive material is good, and an adhesive is also used for a light-sensitive emulsion layer. It was possible to select a material that does not cause fogging and deterioration, and a light-shielding and moisture-proof packaging form of a light-sensitive material could be obtained.

Furthermore, when the label 9 of the light-shielding reader 5 and the tip 7 for unfastening (end-stopping) seal is peeled from this packaging state and loaded into the loading box and pulled out, the folded-back portion of the end light-shielding cover 11 and the leader. The adhesive portion with the edge portion has such an adhesive strength that it can be peeled by losing the unwinding (drawing) torque.

That is, if such a packaging form is used,
The roll photosensitive material does not need to be put in a magazine or the like in advance in a complicated, expensive and heavy packaging form, and can be easily loaded in a loading box (magazine) such as a printer in a bright place, and the operability is easy. The distribution cost is low and the quality is stable, and the effects of light-shielding, moisture-proofing and emulsion resistance can be improved, and safety is also enhanced.

Further, if such a package is made of the core 2 which is shielded from light, the end light-shielding cover 11 may be one in which a hole about the inner diameter of the core is opened. Thus, when the scroll is loaded in the loading box, the inner diameter of the core of the scroll is held by the shaft portion of the box so that the rotation for unwinding (drawing) can be performed more smoothly. In that case, since the inner peripheral surface of the winding core is directly fitted to the shaft portion and does not go through an unstable shading sheet having a pleated shape or a cut shape as in the conventional case,
The photosensitive material can be smoothly rotated when it is pulled out, and it is possible to prevent the photosensitive material from being unduly stressed.

Such packaging of the roll photosensitive material of the present invention is carried out stably and reliably by the method and apparatus of the present invention.

[0028]

EXAMPLES First, examples of the roll photosensitive material of the present invention will be described.

As shown in the perspective view of FIG. 2, an end light-shielding cover 11 having a circular sheet having an outer diameter larger than the outer diameter of the roll photosensitive material and having an adhesive applied on one side thereof is used for the scroll 1 of the roll photosensitive material. Both ends 10A and 10B are concentrically aligned with each other, and the outer edge of the light-shielding cover 11 is cylindrically folded back to the outer peripheral surface of the light-shielding reader 5 joined to the end of the photosensitive material of the scroll 1 of the roll photosensitive material. Scroll 1
The contact surface with is pressed and the adhesive applied to the end light-shielding cover 11 is crushed to adhere to the light-shielding leader surface on the outer peripheral surface of the roll photosensitive material. At this time, at the same time, both end faces 10A, 10A of the scroll 1 of the roll photosensitive material
The end light shielding cover 11 can also be adhered to B by pressing and melting the adhesive.

When the core core 2 is made of a light-shielding material, as shown in the perspective views of FIGS. 4, 5 and 7, the center of the end light-shielding cover 11 corresponds to the inner diameter of the core. It is desirable that a hole 11D having a diameter to be formed is formed. The end face of the core and the light shielding cover 11 are adhered to each other to secure light shielding. When the inner diameter surface of the winding core 2 is opened when it is loaded in the loading portion of a printer or the like, the roll photosensitive material
Since the 10 cores can be received by the shaft portion of the loading portion, the feeding can be smoothly performed. When both end surfaces of the winding core 2 are closed, the roll photosensitive material 10 is loaded in the box of the loading section, and the roll photosensitive material 10 is fed out while rolling.

In any case, the roll light-sensitive material 10 thus packaged in a light-proof and moisture-proof package breaks the label 9 of the seal (end stop) seal that seals the tip 7 of the light-shielding reader 5, and is supplied to the printer in a bright room state. After the printer is pulled out, the printer pulls out the light-shielding leader, cuts the part of the bonding tape, collects the leader portion, and pulls out the photosensitive material. It is possible to start driving.

When the light-shielding leader 5 is pulled out, the adhesive surface with the end light-shielding cover 11 is peeled off, and the light-shielding leader 5 and the edge portion of the photosensitive material 3 following it are pulled out. In the case where it is adhered to the end light-shielding cover 11, it also comes out while being peeled off.

Further, when the outer peripheral portion of the end light-shielding cover 11 is folded back into a cylindrical shape on the outer peripheral leader surface of the roll photosensitive material 10, a wrinkle-like wrinkle occurs in the cylindrical portion, but the adhesion is moderate. The pleated portion is also crushed, so that the purpose of shading is completely achieved by the refraction effect of light and the unwinding (drawing) action is smoothly performed.

Then, the end face of the winding core 2 and the end light-shielding cover 11 are also adhered, so that the photosensitive material is completely shielded from light. Further, the inner peripheral surface of the winding core 2 is smoothly fitted to the shaft portion, and the photosensitive material is pulled out without receiving unnecessary stress.

In this way, the light-shielding and moisture-proof packaging of the roll photosensitive material 10 is not overwhelmed by a magazine or cassette,
It can now be realized with a simple packaging form.

An example of a method of carrying out light-shielding and moisture-proof packaging of such a long roll photosensitive material 10 is as follows.

(A) Position the scroll 1 of the roll photosensitive material with a light-shielding / moisture-proof leader wound around the winding core, and arrange the end light-shielding cover 11 so as to be concentric with it. On the other hand, pressing is performed in the direction of the central axis (core axis of the winding core), and the fold-back narrowing molding is performed so that the outer edge portion covers the outer peripheral portion of the scroll 1 of the roll photosensitive material. The roll photosensitive material is adhered to the light-shielding leader surface on the outer periphery of the scroll 1.

(B) The bonding method is the contact area between the end light-shielding cover 11 and each polyethylene surface of the light-shielding leader 5 shown in the layer structure sectional view of FIG. 12 (a), the polyeletin surface of the cover 11 and the core. A scroll 1 of the leader 5 and the roll photosensitive material is made of a material in which the contact area with the end surface of 2 is melted and adhered by the heating of the pressing means, or an adhesive applied to one surface of the end light shielding cover 11. The edge portion of the photosensitive material 3 and the end portion of the winding core 2 can be adhered to each other by applying pressure and further heating.
It is preferable that the edge portions of are not adhered. Therefore, it is possible to achieve the purpose by setting the length of the winding core to be slightly larger than the width of the photosensitive material.

However, when the outer peripheral portion of the end light-shielding cover 11 is cylindrically covered with the outer peripheral surface of the roll light-sensitive material, a rigid plate is made into a rigid male type like an ordinary metal drawing process. In the processing performed with a female mold, a strong pressure is applied, and there is a high possibility that pressure fog will occur on the emulsion surface of the light-sensitive material, and it is necessary to devise a method to avoid this. In the method of the present invention, as shown in FIG. 8 (a), an elastic elastic body 43 made by processing a polyurethane material in a ring shape is provided on the inner surface of the cylinder of the female die 41 to prevent a strong pressure from being applied to the surface of the photosensitive material. I achieved that goal. Since the polyurethane material has heat resistance, the female mold 41 shown in FIG.
It is also sufficiently practical in the case of a female type as shown in FIG.

It is to be noted that not only the elastic ring mounted on the inner surface of the cylinder such as the female die 8 (a) but also FIGS.
As shown in the side view of FIG. 3, it is preferable to attach a similar elastic body 42 to the ceiling surface of the cylindrical inner surface to prevent the edges of both end surfaces of the scroll 1 of the roll photosensitive material from being crushed.

The elastic body 42 or 43 may be made of silicone rubber material, synthetic rubber or foamed polyurethane in addition to polyurethane material, and it is also effective to inject high pressure air into the hollow ring of synthetic rubber material.

Further, by using such an elastic body, the above-mentioned bonding can be carried out without any trouble even if the outer diameter of the scroll 1 has some dimensional variation.

Next, an embodiment of a roll photosensitive material packaging apparatus of the present invention using such a roll photosensitive material packaging method of the present invention for light-shielding and moisture-proof packaging will be described with reference to the front view of FIG. 9 and FIG. This will be described with reference to a partial plan view of the long light-shielding cover.

Pallets 21 provided with nests 22 are arranged in series and are intermittently sent from right to left. Each pallet 21
Are arranged at substantially equal intervals and are not shown in the drawing, for example, they are hung on the conveying claws and conveyed one pitch at a time to stop, and finer adjustment for finer positioning is performed.
Squeeze and stop at the bonding position.

The nest 22 is concentrically loaded with and held by the scroll 1 of the roll photosensitive material, to which the end light-shielding cover 11 is not attached or is attached only on one side.

Bare, in FIG. 9, the end light-shielding cover 11
In the figure, one that has been pasted on one side is shown, but first, the process of pasting on one side to the scroll 1 that has not been pasted on one side is started.

Further, the long sheet 11R of the end light-shielding cover 11 runs on the upper part of the running path of these nests 22, and the guide plate 51 is provided on the lower part thereof, and the long sheet 11R is provided.
And a lower die 32 having a punching die lower blade 32A concentrically with the nest 22 is provided at the positioning stop position.
An upper blade 31A corresponding to the upper blade 31A is provided in the upper part of the upper die 31 in a cylindrical shape, and a diaphragm die 41 is concentrically fixed to the inner surface (inner peripheral surface) of the cylindrical shape. The lower end 41A of the aperture die 41 opens in a conical shape so that the outer peripheral portion of the scroll 1 made of a photosensitive material having an outer peripheral portion provided with a loose-fitting seal can be easily inserted, and a ring-shaped groove 41C is formed in the middle of the cylindrical inner diameter portion 41B. Is provided, and a polyurethane ring is fitted therein as the elastic body ring 43. The portion of the inner diameter portion 41B is not so small that the outer peripheral portion of the scroll 1 is restricted, and only the inner diameter of the ring 43 is smaller than the outer diameter of the scroll 1.

On the other hand, the pallet 21 and the long end light-shielding cover 11R attached to the pallet 21 and traveling in synchronization with the traveling of the nest 22 are lowered from the tip blade portion 31A by lowering the upper die 31 at the positioning stop position. The outer edge portion of the end light-shielding cover 11 punched and punched by the blade 32A moves along the outer circumference of the scroll 1 of the roll photosensitive material by the ring 43 as the diaphragm die 41 set concentrically with the upper die 31 descends. And is squeezed into a cylindrical shape, and the contact surface between the end light-shielding cover 11 and the scroll 1 is adhered by the adhesive applied to the cover 11.

The adhesive is adhered between the applied adhesive and the light-shielding reader on the outer peripheral portion of the roll photosensitive material scroll 1 only by the forced elastic pressure applied by the polyurethane ring as the elastic ring 43. In addition to the above, the adhesion is applied on the end light-shielding cover 11 by applying a heating means 45 such as nichrome wire to the diaphragm die 41 as shown in FIG. 8C. It is also possible to temporarily melt the agent and bond it together with the pressure applied by the elastic body 43. In that case, it is desirable to provide a cooling pipe 46 as shown in FIG. 8D to protect the elastic body 43.

When heating is involved as described above,
As shown in the layer structure diagram of FIG. 12 (b), an EVA layer is provided on the outermost constituent layer of the end light shielding cover 11, and the same EVA constituent layer of the light shielding reader constituting the outer peripheral surface of the scroll 1 is heated. Can be welded to achieve adhesion. In this case, it is not necessary to apply an adhesive agent to the end light shielding cover 11 in advance.

Further, among the above-mentioned bonding, bonding with an adhesive can be performed between both end surfaces of the scroll 1 of the roll photosensitive material and the end light shielding cover 11, but the stability of the transport of the photosensitive material is ensured. Considering that, the both end surfaces and the light shielding cover 11
It is desirable to avoid adhesion with. In that case, diaphragm type 41
In order to protect the end surface of the scroll 1, it is necessary to provide the elastic body 42 on the upper ceiling surface of the scroll 1.

In any of the above-mentioned adhesion methods, the adhesion area is not so large and is a very small area. For example, by pulling the light-shielding reader 5 or the film 3, the scroll 1 is rotated and the adhesion area is reduced. It is peeled off and pulled out, so to speak, the adhesive has a temporary adhesive force.

Further, as shown in the perspective views of FIGS. 4, 5 and 7, a concentric circular hole 11D is formed in the central portion of the end light-shielding cover 11 to open the inner diameter portion of the winding core 2. Can be shaped.

As shown in the plan view of the end light-shielding cover 11R in FIG. 11, circular holes 11D having the same diameter as the inner diameter of the winding core and having the same concentricity are previously formed in the long end light-shielding cover 11R at equal intervals. If this is done, the end light-shielding cover 11 can be easily positioned for the purpose of making the fine adjustment possible with the circular hole 11D as a reference. The end light-shielding cover 11R of the long roll sheet after punching out the end light-shielding sheet 11 is wound up though the punching hole 11C is left open although not shown.

When the packaging of the one-side light shielding cover is completed, the other one-side light shielding cover packaging is repeated in the same manner to complete the entire packaging.

The end portion 7 of the outer peripheral light-shielding leader 5 of the roll photosensitive material 10 shown in the perspective views of FIGS. 3 and 4 is not covered with the label 9 to prevent unwinding (end stop). The part is heat-sealed.

Even if this seal is not provided, it is not particularly required as long as the light-shielding cover 11 is sealed from both sides by covering the outer peripheral edge of the cylindrical surface of the light-shielding reader 5. However, if the unsealing seal of the scroll 1 is applied as described above when the light shielding cover 11 is adhered, the operation can be performed easily and surely.

[0058]

According to the present invention, light-shielding and moisture-proof packaging of roll photographic material such as color photographic paper can be carried out without heavy packaging in magazines or cassettes, and can be easily loaded into a printer or the like in a bright state. I can do it easily. Since it is not necessary to procure magazines and cassettes, the weight is light and easy to handle, and the packaging cost can be significantly reduced.

The packaging method of such a packaging form is also simple and reliable, and the packaging apparatus is also capable of intermittently conveying the long light-shielding cover and the scroll in synchronization and simultaneously at the light-shielding and moisture-proof packaging position by the light-shielding cover. Since it is possible to perform the squeeze adhesion processing, the apparatus is simple and the cost is low, and it is possible to provide a highly efficient, reliable and stable packaging processing apparatus.
