Abstract

PURPOSE:To superpose two image recording material uniformly one over the other without wrinkling and to prevent an image irregularity from being generated by carrying the two image recording materials synchronizing with each other at a carrying speed slower than the rotary moving speed of the outer peripheral surface of a rotary drum. CONSTITUTION:The two image recording materials are carried by clamping and carrying rollers 114 synchronizing with each other through different paths and sent in between a superposing roller 120 and the rotary drum 116. The image recording materials which are thus sent in are clamped and superposed on over the other in order by the superposing roller 120 and rotary drum 116 and wound around the outer periphery of the rotary drum 116 while superposed one over the other. At this time, the outer peripheral surface of the rotary drum 116 rotates and moves at the rotary moving speed faster than the conveying speed by the clamping and carrying rollers 114, so the image recording materials do not slacken after their head end parts are clamped by the rotary drum 116 and superposing roller 10. Consequently, each image recording material is superposed uniformly without wrinkling and no image irregularity is generated.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an image recording apparatus that performs image recording processing by winding two different image recording materials around the outer periphery of a rotating drum as the drum rotates.

[Prior Art] Image recording apparatuses are known that perform image recording processing by tightly wrapping an image recording material around the outer periphery of a rotating drum.

In this type of image recording apparatus, for example, a photosensitive material and an image receiving material are used as image recording materials, and the rotating drum is a heating drum. On the outer periphery of this heating drum,
Part of the outer periphery of the overlapping roller and the endless pressure belt is pressed. After the image has been exposed, the photosensitive material and the image-receiving material are conveyed by a nipping conveyance roller and sent together between a heating drum and an overlapping roller, and are successively nipped and overlaid by the heating drum and overlapping roller. Furthermore, in this state, it is tightly wound around the outer periphery of the heating drum. Here, both materials are sandwiched and conveyed between a heating drum and an endless pressure belt, while the photosensitive material is thermally developed and an image is transferred to the image-receiving material.

[Problems to be Solved by the Invention] By the way, when a photosensitive material or an image-receiving material is fed between a heating drum and a superimposing roller and superimposed on each other, a portion of the leading end comes into contact with the outer periphery of the heating drum, and then Then, it moves along the outer circumference of the heating drum and reaches the pressure contact point between the overlapping roller and the heating drum. Therefore, if the conveyance speed of the photosensitive material or image-receiving material by the nipping conveyance rollers is the same as the rotational movement speed of the outer circumferential surface of the heating drum, the leading edge of the photosensitive material or image-receiving material may become loose after being nipped by the heating drum and the overlapping roller. occurs.

Therefore, in this case, the photosensitive material and the image-receiving material are not superimposed uniformly (they are superimposed with wrinkles).
, This causes image unevenness (transfer misalignment).

The present invention has been made in consideration of the above facts, and an object of the present invention is to provide an image recording apparatus in which a photosensitive material and an image-receiving material can be uniformly overlapped without wrinkles, and in which image unevenness does not occur.

[Means for Solving the Problems] An image recording device according to the present invention has a superposition roller in pressure contact with the outer periphery, and two different image recording materials are successively sandwiched between the superposition roller and the superposition roller. A rotating drum that performs image recording processing by closely wrapping the outer circumference of the overlapping image recording material, and transporting the two overlapping image recording materials through different routes at a transport speed slower than the rotational movement speed of the outer circumferential surface of the rotating drum. and a nipping conveyance roller that conveys the sheet synchronously and feeds the sheet between the overlapping roller and the rotating drum.

[Operation] In the image recording apparatus configured as described above, two different image recording materials are synchronously conveyed by the nipping conveyance rollers along different routes and sent between the overlapping roller and the rotating drum. The image recording materials sent in are successively sandwiched and stacked by a stacking roller and a rotating drum.
They are wrapped tightly around the outer periphery of the rotating drum in an overlapping state.

When each image recording material is fed between the rotating drum and the superimposing roller and superimposed, the outer circumferential surface of the rotating drum rotates at a rotational movement speed faster than the conveyance speed by the nipping conveyance roller. There is no possibility that the leading end of the image recording material will become loose after being held between the rotating drum and the overlapping roller. Therefore, each image recording material is uniformly overlaid without wrinkles, and therefore, image unevenness does not occur.

An endless pressure belt 11 that presses against the outer periphery of the heating drum 116
8 has a structure in which a woven fabric material is coated with rubber. The woven material is sewn with heat-resistant fibers such as aromatic polyamide fibers (for example, Kevlar or Nomex, both registered trademarks of du Pont), and monofilament fibers are used in the width direction of the belt. Improves rigidity in the belt width direction. In addition, the rubber for the coating is silicone rubber containing carbon.

On the other hand, the winding roller 140 is a rubber roller, and its rotating shaft is connected to a motor (not shown) as a driving source. Therefore, the driving force of the motor is directly transmitted to the roller 140, and this winding is caused by the roller 140.
The endless pressure welding belt 118 is rotated, and as a result, the rotational force of the endless pressure welding belt 118 is applied to the heating drum 11 by the frictional force between it and the heating drum 116.
6, and the heating drum 116 is rotated in a driven manner. Further, when the heating drum 116 rotates, a bonding roller 120 disposed in pressure contact with the outer periphery of the heating drum 116 similarly rotates together due to frictional force.

Furthermore, in this case, the squeeze roller 68 and the conveying roller 10
The conveyance speed of the photosensitive material 16 or the image receiving material 108 is set to be about 2% slower due to the transfer speed of the photosensitive material 16 or the image receiving material 108 due to the transfer speed of the photosensitive material 16 or the image receiving material 108 . It is designed to work. In addition, squeeze roller 68
A one-way clutch (not shown) is attached to the drive shaft of the transport roller 114.

A predetermined tension is maintained.

Further, the image receiving material 108 is conveyed between the heating drum 11G and the bonding roller 120 in synchronization with the conveyance of the photosensitive material 16, with the photosensitive material 16 leading by a predetermined length (20 mm in this embodiment). The sheet is fed between the bonding roller 120 and the heating drum 116 so that they are overlapped.

The photosensitive material 16 and the image-receiving material 108 which have been superimposed by the laminating roller 120 are placed between the heating drum 116 and the endless pressure contact bell (118) while remaining in the superimposed state. roller 134
The winding material is sandwiched and conveyed between the rollers 140). When the photosensitive material 16 is heated during this nipping and conveyance, it releases a mobile dye, and at the same time, this dye is transferred to the dye fixed layer of the image-receiving material 108 to obtain an image.

A bending guide roller 142 and a peeling claw 1 are provided at the bottom of the heating drum 116 on the downstream side of the endless pressure belt 118 in the material supply direction.
54 are arranged. Of the photosensitive material 16 and image-receiving material 108 that are sandwiched and conveyed between the endless pressure belt 118 and the heating drum 116, the peeling claw 154 engages only the leading end of the photosensitive material 16 that is overlapped with a predetermined length ahead. The leading end portion can be peeled off from the outer periphery of the heating drum 116, and the bent guide roller 142 wraps around and guides the peeled photosensitive material 16.

A cutter 180 for cutting the photosensitive material 16 and a waste photosensitive material storage box 178 are arranged below the peeling claw 154, and cut the photosensitive material 16 peeled from the outer periphery of the heating drum 116 and separated from the image receiving material 108 into small pieces. The photosensitive materials can be collected in the waste photosensitive material storage box 178.

A drying fan 182 is arranged on the side of the peeling claw 154 for blowing air to the image receiving material 108 to dry it.

A peeling roller 174 and a peeling pawl 176 are arranged above the peeling pawl 154 and near the heating drum 116 to peel off the image receiving material 108 that is separated from the photosensitive material 16 and moves together with the heating drum 116 from the outer periphery of the heating drum 116. It has become. The peeled image-receiving material 108 is accumulated on a tray 184.

Next, the operation of this embodiment will be explained.

The photosensitive material 16 pulled out from the photosensitive material magazine 14 by the nip roller 18 is cut into a predetermined length by the cutter 20 and then conveyed to the exposure section 22. Further, after cutting, the nip roller 18 is reversely rotated, and the pulled out photosensitive material 16 is rewound into the photosensitive material magazine 14. Therefore, the leading end of the photosensitive material 16 is not wasted and is not exposed inadvertently.

The cut photosensitive material 16 is conveyed by a conveyance roller 24 and a conveyance roller 26 and once passes through an exposure section 22,
This leads to flapper 36. Here, the flamper 36 enters and blocks the transport path of the bifurcated photosensitive material 16 located on the lower side of the apparatus, thereby transferring the photosensitive material 16 to the upper side of the apparatus of the flamper 36. Guide to the transport route located at .

Further, the guided photosensitive material 16 is reversed in the reversing section 34 so that its photosensitive (exposure) surface faces upward, and then conveyed from the flapper 36 to the exposure section 22 again. When the photosensitive material 16 is nipped by the conveying roller 26, the driving of the conveying roller 26 is temporarily stopped, and the photosensitive material 16 is placed in a standby state immediately before the exposure section 22.

On the other hand, while the photosensitive material 16 is being conveyed, a pre-scan of the original 54 is performed.

That is, first, the light source 40 is activated, and the reflection mirror 46 enters the optical path of the image light irradiated to the exposure section 22, and the light irradiated via the movable mirrors 42A, 42B and the fixed mirror 44. is reflected in an approximately perpendicular direction. The reflected light is incident on the light detection sensor 56 and detected, thereby determining the image density of the image on the original 54 (in other words, whether the image on the original 54 is like a printed original or a photographic original). is measured, and the exposure conditions for the color adjustment filter (CC filter) and the aperture slit plate 52 are set based on this measured value.

Next, the reflection mirror 4G leaves the optical path of the image light, and the light source 40, moving mirror 42A142B, and lens unit 48 return to their home position (image scanning start position).

Here, the driving of the conveyance roller 24 and the conveyance roller 26 is started again, and the photosensitive material 16 covers the exposure area 22 by 100 mm.
It passes at a speed of /sec. In this case, since the guide plate 28 and the exposure surface glass 30 are arranged in the exposure section 22, the photosensitive material 16 passes between both transport rollers (the exposure section) in a flat shape (while the deformation is corrected). .

At the same time as this photosensitive material 16 is transported (passing through the exposure section 22), the light source 40, movable mirrors 42A, 42B, and lens unit 48 move along the original plate 50 and are placed on the original plate 50. The reflected image light (image light) passes through a plurality of fixed mirrors 44 to the exposure unit 2.
The photosensitive material 16 located at 2 is scanned and exposed.

In this case, since the exposure section 22 is forcibly cooled by the cooling fan 58, exposure failures due to temperature rise will not occur.

When the exposure starts, that is, the driving of the conveyance rollers 24 and 26 is resumed, the flapper 37 is switched upward, and the exposed photosensitive material 16 is thereby conveyed to the reversing section 60 one after another. Further, the photosensitive material 16 is reversed in the reversing section 60 (that is, the image-exposed surface is directed downward) and then sent to the water application section 62 by the conveying rollers 29, 31, 33, 35.

In the water application section 62 , water is applied to the photosensitive material 16 , and the photosensitive material 16 passes through the water application section 62 while excess water is removed by a squeeze roller 68 . The photosensitive material 16 coated with water as an image forming solvent in the water coating section 62 is
The squeeze roller 68 sends it to the thermal development transfer section 104 .

On the other hand, the image receiving material 108 is also pulled out from the receiving material magazine 106 by the nip roller 110, and is further pulled out by the cutter 112.
After the photosensitive material 16 is cut into a length shorter than the photosensitive material 16, it is transported by a transport roller 114 to the thermal development transfer section 1.
Sent to 04.

Further, after cutting, the nip by the nip roller 110 is released, and deformation of the leading end (image forming surface) of the image receiving material 108 due to being nipped for a long time is prevented.

Here, the image-receiving material 108 is conveyed to the thermal development transfer section 104 in synchronization with the conveyance of the photosensitive material 16, and is placed on the bonding roller 120 with the photosensitive material 16 leading by a predetermined length (20 mm in this example). heating drum 116
It is sent between the two and overlapped.

In this case, the bonding roller 120 and the water application section 62
A guide plate 70 is disposed between the squeeze roller 68 and the photosensitive material 1 sent from the squeeze roller 68.
6 is reliably guided to the bonding roller 120. Further, a blade guide 124 is arranged between the bonding roller 120 and the conveying roller 114 for the image receiving material 108, so that the image receiving material 108 is also securely transferred to the bonding roller 120.
You will be guided to.

Pasting roller 120 precedes image receiving material 108
After the tip of the photosensitive material 16 that has been guided is sandwiched between the bonding roller 120 and the heating drum 116, the speed at which the photosensitive material 16 is pinched and conveyed by the heating drum 116 and the bonding roller 120 (in other words, the heating drum 1
Since the conveyance speed of the photosensitive material 16 by the squeeze roller 68 is set to be about 2% slower than the rotational movement speed of the outer circumferential surface of the photosensitive material 16, back tension acts on the photosensitive material 16, causing it to loosen. There is no

Next, when the leading end of the image-receiving material 108 guided to the bonding roller 120 reaches the pressure contact point between the bonding roller 120 and the heating drum 116, it is sequentially overlapped with the photosensitive material 16. In this case as well, since the conveyance speed of the image receiving material 108 by the conveyance roller 114 is set to be slower than the nip conveyance speed of the image receiving material 108 by the heating drum 116 and the bonding roller 120, back tension is applied to the image receiving material 108. It works without causing any slack.

Therefore, the photosensitive material 16 and the image-receiving material 108 are uniformly overlapped without wrinkles.

Moreover, the tension acting on the photosensitive material 16 and the image receiving material 108 is maintained at a predetermined value by the one-way clutch attached to the drive shafts of the squeeze roller 68 and the conveying roller 114, so that excessive tension may cause the photosensitive material 16 and the image receiving material to The material 108 will not be damaged or become untransportable.

Furthermore, in this case, since the image-receiving material 108 is smaller in width and length than the photosensitive material 16, all four sides of the photosensitive material 16 protrude from the periphery of the image-receiving material 108. are superimposed on each other.

The photosensitive material 16 and the image-receiving material 108 which have been superimposed by the bonding roller 120 are placed between the heating drum 116 and the endless pressure belt 118 while remaining in the superimposed state. roller 134
and the wound portion is conveyed while being held between the rollers 140). When the photosensitive material 16 is heated during this nip-conveying process, it releases a mobile dye, and at the same time, this dye is transferred to the image-receiving material 1.
The image is transferred to the dye fixing layer No. 08 to obtain an image.

In this case, the photosensitive material 16 and the image-receiving material 108 are overlapped uniformly without wrinkles, and the peripheral portion of the photo-sensitive material 16 protrudes from the peripheral portion of the image-receiving material 108 on all four sides and extends to the outer periphery of the heating drum 116. Since they are in close contact with each other, a predetermined pressure can be applied without each material shifting during conveyance, and a high-quality image without image unevenness can be obtained.

Furthermore, since the endless press-contact belt 118 is connected to the motor and is directly and forcibly rotated by the roller 140, the winding can be ensured even if the bending rate of the part is large or it is bent at multiple points. rotates at a predetermined speed. Furthermore, since the heating drum 116 has a small resistance to the rotational driving force and is in pressure contact with the endless pressure belt 118 over a wide range, the rotational force from the endless pressure belt 118 is reliably transmitted by friction (the rotational force is (transferred without any loss). For this reason, the endless pressure belt 118
There is no difference in rotational speed between the heating drum 116 and the heating drum 116. Therefore, the photosensitive material 16 sandwiched and conveyed by the endless pressure belt 118 and the heating drum 116
Shearing force is generated between the image-receiving material 108 and the two materials, and a good image can be obtained without causing transfer misalignment.

Furthermore, since the endless pressure contact bell l-118 is electrically conductive, the generation of static electricity due to friction between the heating drum 116 and the endless pressure contact belt 118 or the photosensitive material 16 or the image receiving material 108 is prevented, and it is possible to prevent the generation of static electricity on the image receiving material 108. There is also no fogging in the displayed image.

Thereafter, when the photosensitive material 16 and the image-receiving material 108 are sandwiched and conveyed and reach the lower part of the heating drum 116, the image-receiving material 108
A peeling claw 154 engages with the leading end of the photosensitive material 16 that is conveyed a predetermined length ahead of the photosensitive material 16 , and peels the leading end of the photosensitive material 16 from the outer periphery of the heating drum 116 . Further, the peeled photosensitive material 16 is wrapped around a bending guide roller 142 and bent downward, cut into pieces by a cutter 180, and accumulated in a waste photosensitive material storage box 178.

On the other hand, the image receiving material 108, which is separated from the photosensitive material 16 and moves while remaining in close contact with the heating drum 11G, is dried by the drying fan 182 while being separated from the heating drum 116 and its outer periphery by a peeling claw. 176 , and then sent to a peeling roller 174 . Furthermore, here, the tray 18 is peeled off from the outer periphery of the heating drum 116 by the peeling roller 174 and the peeling claw 176.

As described above, in this embodiment, the photosensitive material 16 and the image receiving material 1 are connected by the heating drum 116 and the bonding roller 120.
08, the photosensitive material 16 is transferred by the squeeze roller 68, and the image receiving material 1 is transferred by the transfer roller 114.
Since the conveyance speed of the photosensitive material 16 and the image receiving material 108 is set to be slow, back tension is generated in the photosensitive material 16 and the image receiving material 108 to prevent loosening, and it is possible to uniformly overlap the photosensitive material 16 and the image receiving material 108 without wrinkles.

In the above embodiment, the photosensitive material 16 and the image receiving material 108 are used as image recording materials, and the photosensitive material 1G is conveyed so as to be located outside the image receiving material 108. However, the present invention is not limited to this. The present invention is applicable even when the photosensitive material 16 is positioned inside and transported, and is also applicable not only to these materials but also to other sheet-like image recording materials.

[Effects of the Invention] As explained above, the image recording apparatus according to the present invention has the advantage that a photosensitive material and an image-receiving material can be overlapped uniformly without wrinkles, and image unevenness does not occur.
