[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sheet material winding core for winding a sheet-shaped material such as a light-sensitive material or an image-receiving material on the outer periphery.

[0002]

2. Description of the Related Art As an image recording material, there is known an image recording apparatus which performs an image recording process using, for example, a photosensitive material and an image receiving material.

In this type of image recording apparatus, the photosensitive material and the image receiving material are respectively wound and accommodated in roll-shaped magazines in a light-shielding magazine. Each time an image recording process is performed, a pull-out roller is used. It is sandwiched and used by sequentially pulling it out. Further, the image recording apparatus is provided with an exposure section for imagewise exposing the photosensitive material and a water application section for applying the image forming solvent to the exposed photosensitive material. Further, a heat development transfer section is arranged beside the water application section. Further, a plurality of guide plates and transport rollers are arranged between the exposure section, the water coating section, and the heat development transfer section, and connect the respective sections.

The photosensitive material, which is pulled out from the magazine by a predetermined size and cut, is exposed with an image while being nipped and conveyed by conveying rollers, and further, water as an image forming solvent is applied in the water application section, and then the heat development transfer section. Sent to. On the other hand, like the photosensitive material, the image receiving material is pulled out from the magazine by a predetermined size and cut, and is fed to the heat development transfer section in synchronization with the photosensitive material by the conveying roller. In the heat development transfer section, the photosensitive material after water application is superposed on the image receiving material, and while being conveyed in this state, the photosensitive material is thermally developed and the image is transferred to the image receiving material to form a predetermined image on the image receiving material. (Recorded) After that, the photosensitive material and the image receiving material are separated, and the image receiving material on which the image is recorded is taken out of the apparatus.

In such a conventional image recording apparatus, since the photosensitive material separated from the image receiving material is discarded as described above, it is necessary to collectively collect the photosensitive material. In this case, the photosensitive material after being separated from the image receiving material,
It is conceivable that the winding core formed in a tubular shape may be sequentially wound around the outer circumference and accumulated.

By winding and accumulating on such a winding core, it is possible to efficiently accumulate in a small space.
The light-sensitive material coated with water as described above may curl after it is heated and separated from the image-receiving material. However, if it is wound around a winding core and accumulated, it may be accumulated regardless of the occurrence of curl. Therefore, it is not necessary to provide a curling presser plate or to make a fold (corrugation) on the photosensitive material itself to increase the rigidity, and the structure is simple and the cost is low.

[0007]

By the way, in the case where a sheet-like material such as a photosensitive material is wound and accumulated on the winding core as described above, the winding core and the winding core are naturally wound thereafter. It is necessary to separate from the sheet material.

However, after the sheet material such as the above-described photosensitive material is wound around the winding core in layers, it is not possible to separate (withdraw) only the winding core from the wound sheet material in close contact with the layers. It is difficult, and measures against this point are desired.

In consideration of the above facts, the present invention not only can roll up and accumulate sheet-shaped materials such as photosensitive materials and image receiving materials, but also requires labor and labor from the rolled-up sheet material. It is an object of the present invention to obtain a winding core for winding a sheet material, which can be easily separated without using a simple structure.

[0010]

In order to achieve the above object, a winding core for winding a sheet material according to the first aspect of the invention is formed in a substantially cylindrical shape as a whole, and has three cores along the axial direction. A core member that is divided into two or more parts and that is capable of contacting and separating from each other in the radial direction, and that winds a sheet-shaped material around the outer periphery; and a core member that is provided inside the core member and that has three or more members. An outer diameter expansion / contraction mechanism for expanding / contracting the outer diameter of the core member by bringing the divided main body parts into contact with and separating from each other in the radial direction,
It is provided inside the core member, and the outer diameter of the core member is
In the contracted state, it projects outside from the surface of the main body.
And a plurality of peeling members .

In the winding core for winding the sheet material according to the first aspect, the core member is constituted by the main body portion divided into three or more, and the sheet material is the core member (each divided main body portion). Are successively wound around the outer periphery of the film in layers.

Here, after the sheet material is wound around the winding core member in layers, when the winding core member is separated (withdrawn) from the layered winding sheet material, the outer diameter expansion / contraction mechanism is operated. As a result, the main body divided into three or more parts approach each other in the radial direction, and the outer diameter of the winding core member is reduced. Thereby, the core member can be easily separated from the sheet material wound in a layered manner.

As described above, not only can sheet-shaped materials such as light-sensitive materials and image-receiving materials be wound and accumulated, but they can also be easily separated from the wound sheet materials without labor or labor. be able to. Further, since the winding core member is divided into three or more along the axis, it can be expanded and contracted to a large degree over the entire circumference of the wound sheet material, and the wound sheet material is wound in a layered manner. The core member can be reliably separated from the taken sheet material.

"Sheet material" and "sheet material"
Includes both so-called cut paper and continuous so-called roll paper.

[0015]

Further, in the winding core for winding the sheet material according to the first aspect , the outer diameter of the winding core member is reduced, that is, after the sheet material is wound in layers on the winding core member. When the outer diameter of the core member is reduced in order to separate (pull out) the core member from the sheet material, the plurality of peeling members project outside from the surface of the main body. Therefore, even if the outer diameter of the core member is reduced, even if the sheet material is still in close contact with the core member, the sheet material can be forcibly peeled from the surface of the core member (each main body). Therefore, the core member can be more surely separated from the sheet material wound in close contact with the core member.

As the peeling member, a pin-shaped peeling pin, a cylindrical peeling piece, a leaf spring-shaped peeling spring, or the like can be applied.

Engagement with the end edge prevents the sheet material from being misaligned along the axial direction of the core member. Therefore, the sheet material can be more evenly (efficiently) wound around the outer periphery of the core member (each main body portion). Therefore, the core member can be more easily separated from the sheet material wound in close contact in layers.

The core for winding the sheet material of the invention according to claim 3 is the core for winding the sheet material according to claim 2 , wherein a pair of rubbers are used as the stopper members.

As a result, when the sheet material of each size is wound around the outer circumference of the core member, even if the size of the wound sheet material is different, the winding deviation of the sheet material along the axial direction of the core member can be ensured. Can be prevented.

Further, the core of the sheet material winding of the invention according to claim 4 is the core of the sheet material winding according to any one <br/> of claims 1 to 3 A sticking portion provided on the surface of the main body portion corresponding to the leading portion of the sheet-shaped material wound around the outer periphery of the winding core member, and the leading portion of the sheet-shaped material being attached first And the width of the pasted portion along the circumferential direction of the member

In the laser light irradiating section 36, laser light based on the image data is emitted to irradiate the photosensitive material 14 located in the exposing section 34. As a result, the photosensitive material 14 is scanned and exposed with an image based on the image data.

Then, the exposed photosensitive material 14 is sent to the water coating section 38. In the water application section 38, water is sprayed from the spray tank 40 toward the photosensitive material 14 being conveyed, and water is applied to the photosensitive material 14. After that, the photosensitive material 14 coated with water is sent by the carrying roller 32 into the space between the pair of endless belts 60 and 62 of the heat development transfer section 58.

On the other hand, as the photosensitive material 14 is scanned and exposed, the image receiving material 42 is also pulled out from the material receiving magazine 44 by the nip roller 46 and conveyed. Image receiving material 42
Is pulled out by a predetermined length, the cutter 48 is operated and the image receiving material 42 is cut into a predetermined length.

After the cutter 48 is operated, the cut image-receiving material 42 is guided by the guide plate while the conveying roller 5 is being guided.
Transported by 0, 52, 54, 56. Image receiving material 4
When the front end portion of the second sheet 2 is nipped by the transport roller 56, the image receiving material 42 is in a standby state immediately before the heat development transfer section 58.

Then, as the photosensitive material 14 is fed between the pair of endless belts 60 and 62 by the feeding roller 32 as described above, the feeding of the image receiving material 42 is restarted and the pair of endless belts 60 and 62 is restarted. The image receiving material 42 is fed integrally with the photosensitive material 14 into the space.

As a result, the photosensitive material 14 and the image receiving material 42
Are overlapped with each other, and the overlapping photosensitive material 14 and image receiving material 42 are nipped and conveyed while being heated by the heating plate 66. As a result, the image exposed on the photosensitive material 14 is transferred to the image receiving material 42, and an image is formed on the image receiving material 42.

Further, when these are discharged from the pair of endless belts 60 and 62, the peeling claw 68 engages with the leading end portion of the photosensitive material 14 which is conveyed a predetermined length ahead of the image receiving material 42, and the photosensitive material 14 is exposed. The tip of the material 14 is peeled off from the image receiving material 42. Further, the photosensitive material 14 is used as the photosensitive material discharge roller 70.
Are transported by and accumulated in the accumulating device 90.

On the other hand, the image receiving material 42 separated from the photosensitive material 14 is used as the material receiving discharge rollers 72, 74, 76, 78, 80.
The sheet is conveyed by and discharged to the tray 82.

In the accumulating device 90 in which the photosensitive material 14 is accumulated, the photosensitive material 14 separated from the image receiving material 42 by the separating claw 68 and sent out by the photosensitive material discharge roller 70 is guided by the guide roller 116 to the endless belt 1.
It is guided and fed between 14 and the core 130. As a result, the photosensitive material 14 has the endless belt 114 and the winding core 130.
It is sequentially wound around the winding core 130 while being sandwiched between and.

In this stacking device 90, the photosensitive material 14 to be wound up is heated after being coated with water and has an adhesive property so that it can be securely wound around the winding core 130. This is particularly effective when accumulating sheets having adhesiveness that are difficult to accumulate one by one.

In this case, in the core 130 of the stacking device 90, the core member 132 is detected by detecting the position of the rotational position detecting phase plate 172 provided on the core member 132.
And the entrance of the photosensitive material 14 are synchronized with each other, and the leading portion of the photosensitive material 14 is first attached to the attaching portion 170. Further, here, the surface of the sticking portion 170 is formed to have a surface roughness R _Z = 0.1 μ or less (in other words, since it is formed in a mirror state), the sticking portion 170 has a photosensitive material. The leading portion of 14 becomes easier to stick, and the photosensitive material 14 can be reliably wound around the outer periphery of the core member 132.

Further, in this case, in the core 130, when the photosensitive material 14 is sequentially wound around the outer periphery of the core member 132 in a layered manner, the stopper rubber 160 or the stopper rubber 162 is applied to both end edges of the photosensitive material 14 in the width direction. The photosensitive material 1 along the axial direction of the winding core member 132.
4 winding deviation is prevented. Therefore, the photosensitive material 14 can be more evenly (efficiently) wound around the outer periphery of the core member 132 (the first main body portion 132A, the second main body portion 132B, and the third main body portion 132C).

Further, in the winding core 130, each protrusion 15 of the winding core member 132 (first main body portion 132A, second main body portion 132B, and third main body portion 132C) as shown in FIG.
0 is located in the holding portion 148 of the cam 140 (cam groove 146), and this state is maintained by the spring 152 and the spring 153. Therefore, the first
The main body portion 132A, the second main body portion 132B, and the third main body portion 132C are in a state of being separated from each other, and their mutual approach movements (that is, the support shaft 142) are restricted. Therefore, the winding core 130 (the winding core member 13
2) does not reduce the diameter carelessly.

The photosensitive material 14 is wound on the core 130 (core member 1
32), the winding diameter gradually increases as it is wound around 32), and the roller 108 forming the buffer portion 126 of the endless belt 114 moves (shifts) to the right in FIG. 12 along the guide groove 122, and the winding diameter increases. The apparent increase or decrease in the wrapping length of the endless belt 114 due to this is absorbed.

In this way, the photosensitive material 14 is wound around the winding core 130.
Since the material is wound around the (core member 132) and accumulated, even if the photosensitive materials 14 having different sizes are mixed, the photosensitive materials 14 can be efficiently accumulated without waste. Also, the winding core 130
Since the (core member 132) and the endless belt 114 are sandwiched and accumulated, the photosensitive material 14 does not curl. Further, for this reason, it is not necessary to provide a press plate for preventing curl or to make a fold (corrugation) on the photosensitive material 14 to increase the rigidity, so that the structure is simple and the cost is low.

In this stacking device 90, the upper body 9
When 2 is rotated around the support shaft 96 with respect to the lower main body 94 to open the inside of the device, as shown in FIG.
0 is exposed. Therefore, the photosensitive material 14 accumulated inside can be easily taken out and maintenance can be performed.

Further, in the stacking device 90, the upper body portion 92 that supports the winding core 130, the plurality of rollers 98, and the like.
Since the device is configured as a unit by the lower main body portion 94, the device can be applied not only to the image recording device 10 but also to other devices, and is not limited to the photosensitive material 14 and has, for example, adhesiveness. Even such sheet-like materials can be reliably accumulated, and the versatility is greatly expanded.

Furthermore, the winding core 130 of the integrated device 90.
Is a first body portion 132 in which the core member 132 is divided into three parts.
A, second body portion 132B, and third body portion 132C
Since the outer diameter can be reduced, the photosensitive material 14 is wound up and integrated, and then the core 1
The 30 can be easily separated (pulled out) from the photosensitive material 14.

That is, when the photosensitive material 14 is wound around the winding core 130 in layers and the winding core 130 is separated (withdrawn) from the photosensitive material 14 wound in layers,
First, the winding core 130 and the photosensitive material 14 together with the lower body 94
Remove from. Next, the handle 154 is operated to rotate the support shaft 142, that is, the cam 140. Cam 1
When 40 is rotated together with the support shaft 142, the inner peripheral wall of the cam groove 146 engages with the protrusion 150, and thus the protrusion 150, that is, the first main body portion 132A and the second main body portion 13 of the winding core member 132.
2B and the third main body portion 132C are attracted to each other in a direction in which they approach each other in the radial direction (that is, toward the support shaft 142), and the outer diameter of the winding core member 132 (winding core 130) is reduced. (The state shown in FIG. 6). As a result, the photosensitive material 14 wound in close contact with the layer is wound around the core 130.
Can be easily separated (pulled out).

Further, in this case, in the core 130, the surface of the core member 132 other than the attaching portion 170 is
Since the surface roughness R _Z = 10 μm or more is formed, the photosensitive material 14 is formed at a portion other than the attaching portion 170.
Becomes difficult to adhere to the core member 132. Therefore, the photosensitive material 14 can be easily peeled off from the surface of the core member 132, and the core 130 can be more surely separated from the photosensitive material 14 that is closely wound.

Further, in the winding core 130, the winding core member 132
In order to separate (extract) the core 130 from the photosensitive material 14 after the photosensitive material 14 has been wound around the core 130 (outer periphery of the core member 132) in a layered state. When the outer diameter of the winding core 130 is reduced, a plurality of peeling pins are formed from the surface (through hole 156) of the winding core member 132 (the first main body 132A, the second main body 132B, and the third main body 132C). 166 projects to the outside. Therefore, even if the outer diameter of the winding core 130 is reduced, even if the photosensitive material 14 tries to adhere to the surface of the winding core member 132, the photosensitive material 14 is forcibly pressed.
The core 130 can be peeled off from the surface of (the first main body portion 132A, the second main body portion 132B, and the third main body portion 132C), and the core 130 can be more reliably removed from the photosensitive material 14 that is closely wound. Can be separated.

Thus, the winding core 1 according to the present embodiment
The sheet 30 is not only capable of winding and accumulating a sheet-shaped material such as the photosensitive material 14, but also can be easily separated from the photosensitive material 14 after being wound, without requiring labor and labor.

Further, since the winding core 130 has a structure in which the winding core member 132 is divided into three along the axial direction, it is composed of a first main body portion 132A, a second main body portion 132B, and a third main body portion 132C. The sheet material such as the wound photosensitive material 14 can be expanded or contracted to a large extent over the entire circumference, and can be reliably separated from the wound sheet material in close contact with each other in layers.

Further, the winding core 130 has a handle 154.
By operating the cam 140 to rotate the cam 140, the first main body portion 132A and the second main body portion 132 of the winding core member 132 are operated.
B and the third main body portion 132C can be moved toward and away from each other in the radial direction to reduce the outer diameter, and when the handle 154 is released, the spring 152 and the spring 1 are released.
Since the outer diameter can be automatically expanded by the force of 53, the outer diameter can be expanded / contracted by an extremely easy operation, and labor and labor are not required.

In the above-described embodiment, the winding core member 132 is divided into three parts and is composed of the first main body portion 132A, the second main body portion 132B, and the third main body portion 132C. However, not limited to this, the core member 1
It is also possible that 32 is divided into four or more.

Further, in the above-described embodiment, the photosensitive material 14 cut into each size is used as the sheet-shaped material.
However, the present invention is not limited to this and can be applied to continuous so-called roll paper.

Further, in the above-described embodiment, the example in which the peeling pin 166 is applied as the peeling member has been described, but the peeling member is not limited to such a pin-shaped peeling pin 166, and may be, for example, a cylinder. A strip-shaped strip or a leaf-spring strip spring may be used.

Further, in the above-mentioned embodiment,
