BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a photosensitive material drying apparatus, and more particularly to a photosensitive material drying apparatus for drying a photosensitive material by blowing warm air onto it.

0002

2. Description of the Related Art Conventionally, a photosensitive material drying apparatus for drying a photosensitive material such as a film by blowing hot air thereon has been constructed as shown in FIG. According to this, a plurality of rollers 72 are arranged in a staggered manner at equal intervals inside the photosensitive material drying device 70, and the plurality of rollers 72 form a transport path for the film 74 extending in the vertical direction. A plurality of hot air supply chambers 76 are arranged near the roller 72 with a conveyance path for the film 74 interposed therebetween. Hot air supply room 76
Hot air generated by a fan and a heater (not shown) is supplied to the heater. A hot air outlet 78 is provided on the film conveyance path side of each hot air supply chamber 76 along the film conveyance direction.
There are two. The hot air supplied to the hot air supply chamber 76 passes through the hot air outlet 78 to the film 74 and the roller 7.
It is sprayed near the upstream side in the conveying direction of the film 74 at the contact portion with the film 74 . This dries the film 74.

By the way, when shortening the drying time in a drying device that dries the film by blowing hot air onto it, there are problems such as curling of the film if the temperature of the hot air is increased, so it is necessary to blow hot air onto the film. It is often necessary to increase the amount to shorten the drying time. However, when the distance between the hot air outlet 78 and the film 74 is reduced in order to increase the amount of hot air blown in the conventional photosensitive material drying apparatus 70, the hot air is directed perpendicularly to the film 74. As a result, the drying efficiency in the vicinity of the contact area between the film 74 and the roller 72 deteriorated, resulting in uneven drying.

In order to solve this problem, a pair of hot air discharge ports 78 arranged on the upstream and downstream sides of the film conveyance path with the roller 72 in between blows hot air toward the vicinity of the contact area between the film 74 and the roller 72. A photosensitive material drying apparatus that discharges air has been proposed (Japanese Patent Laid-Open No. 1-123236).

In this photosensitive material drying apparatus, the film 74
By discharging hot air toward the upstream side (in the direction of arrow E in FIG. 7) and the downstream side (in the direction of arrow F in FIG. 7) of the roller 72 at the contact area between the film 74 and the roller 72, the contact between the film 74 and the roller 72 is Moisture accumulated near the contact portion is evaporated to prevent uneven drying of the film 74. In addition, the hot air outlet 78
The highly humid air that is discharged from the film 74 and has evaporated the moisture from the film 74 is released from the exhaust hole 79 formed between the two warm air discharge ports 78 of the hot air supply chamber 76 in the opposite direction to the film 74. There is.

[0006] In addition, in order to remove high-humidity air that has accumulated in the vicinity of the contact area between the film 74 and the roller 72 and promote drying, heating is applied toward the upstream side of the contact area of each roller 72 with the film 74. A drying section that discharges air has also been proposed.

[0007]

However, in the photosensitive material drying apparatus 70 having the above structure, the hot air is discharged from the two hot air discharge ports 78 disposed on the upstream side and the downstream side of the film transport path with the roller 72 in between. In a photosensitive material drying device that discharges hot air near the contact area between the film 74 and the roller 72, two hot air discharge ports 7 of a hot air supply chamber 76 are directed toward the film 74.
8, and this discharged hot air is mainly discharged from the discharge hole 79 between the hot air discharge ports 78 formed in the hot air supply chamber 76, so that the air after the drying process is The high humidity air remains near the film 74 because the air cannot be discharged quickly enough. For this reason, there arises a disadvantage that the drying efficiency of the film 74 becomes poor.

In addition, in the drying section where hot air is blown to the upstream side of the roller 72 near the contact area between the film 74 and the roller 72, the leading edge of the film 74 conveyed by the roller 72 comes into contact with the roller 72, causing the film to dry. If the conveyance speed of the film 74 is uneven, the film 74 is always
In a photosensitive material drying apparatus that blows hot air near the upstream side of the roller 72 at the contact area between the roller 72 and the roller 72, the hot air outlet 78
Since the distances between the two are equally spaced, the hot air is not blown evenly in the conveying direction, and there are parts of the film 74 where the hot air is blown at the same point, resulting in uneven drying of the film 74. Sometimes.

In consideration of the above-mentioned facts, the present invention has been developed to prevent uneven drying of the photosensitive material even if the conveyance speed of the photosensitive material such as a film is uneven, and to reduce the temperature that is blown onto the photosensitive material resulting in high humidity. It is an object of the present invention to provide a photosensitive material drying device that can efficiently discharge wind from near the surface of a photosensitive material and has good drying efficiency.

[Means for Solving the Problems] A photosensitive material drying apparatus according to claim 1 of the present invention blows hot air onto the surface of a photosensitive material moving along a conveyance path formed by arranging a plurality of rollers. A photosensitive material drying apparatus for drying the photosensitive material, comprising: a plurality of hot air supply chambers provided along a photosensitive material conveying path; and a plurality of hot air supply chambers provided in communication with the hot air supply chambers, respectively corresponding to the plurality of rollers, for drying the photosensitive material. a pair of hot air discharge ports each blowing hot air near the contact area with the roller and the hot air outlet openings arranged facing outward from being parallel to each other; a through hole whose end portion facing the photosensitive material transport path is disposed between the pair of hot air discharge ports and is used for discharging hot air after being blown onto the photosensitive material; It is characterized in that it has a discharge path provided between the through holes and serving as a hot air discharge section together with the through hole.

A photosensitive material drying apparatus according to a second aspect of the present invention is a photosensitive material drying apparatus that blows warm air onto the surface of a photosensitive material that moves along a conveyance path formed by arranging a plurality of rollers to dry it. a plurality of hot air supply chambers provided along the photosensitive material conveyance path; and contact portions between the photosensitive material and the rollers, each provided in communication with the hot air supply chambers and corresponding to the plurality of rollers, respectively. a first pair of hot air outlets that are substantially parallel to each other and are arranged to blow hot air into the vicinity and face the conveying direction of the photosensitive material; a second pair of hot air discharge ports that are substantially parallel to each other and are arranged facing in a direction opposite to the direction in which the material is conveyed; a through hole whose end on the road side is disposed between the pair of hot air discharge ports and for discharging hot air after being blown onto the photosensitive material; and a through hole provided between the plurality of hot air supply chambers; It is characterized by having a discharge path which serves as a hot air discharge section together with the through hole.

0012

[Function] In the photosensitive material drying apparatus according to claim 1 of the present invention having the above configuration, the pair of hot air discharge ports arranged in the hot air supply chamber are arranged on the downstream side in the conveyance direction of the roller at the contact area between the photosensitive material and the roller. A warm air discharge port discharges warm air to the vicinity, and a warm air discharge port discharges warm air to the vicinity of the upstream side in the conveying direction of the roller.

[0013] As a result, the distance dimension along the conveyance direction of the hot air blown onto the surface of the photosensitive material is different, and the hot air blown onto the photosensitive material conveyed by the rollers is heated after drying the photosensitive material. The air is discharged from the through hole formed in the air supply section, and also from the discharge path formed between adjacent warm air supply chambers. This discharge passage can be formed wider than the through hole formed in the hot air supply section. The hot air blown onto the photosensitive material from the through hole of the hot air supply chamber and the discharge path between the adjacent hot air supply chambers can be efficiently discharged from near the surface of the photosensitive material. Also,
The hot air newly discharged from the hot air discharge port can reliably dry the surface of the photosensitive material.

In the photosensitive material drying apparatus according to the second aspect of the present invention, the pair of hot air discharge ports disposed in the hot air supply chamber discharge hot air substantially in parallel. Furthermore, there is a warm air supply chamber that discharges hot air from approximately parallel warm air discharge ports to two locations upstream of the roller in the contact area between the photosensitive material and the roller, and a Warm air supply chambers that discharge warm air from two approximately parallel hot air discharge ports near the downstream side are alternately arranged along the conveyance path. As a result, a plurality of spacing dimensions are formed along the conveyance direction of the hot air blown onto the surface of the photosensitive material. Furthermore, the hot air discharged from one of the pair of hot air discharge ports arranged in these hot air supply chambers is mainly discharged from the through hole formed in the hot air supply chamber. However, the hot air discharged from the other hot air outlet can be discharged through the adjacent hot air supply chamber as a discharge path.

These photosensitive material drying devices can efficiently exhaust air after drying the photosensitive material,
Furthermore, each time the leading edge of the photosensitive material that is being conveyed by the roller comes into contact with the roller, even if there is unevenness in the conveyance speed of the photosensitive material, hot air is less likely to be blown onto a certain part of the photosensitive material, and the photosensitive material can be dried almost uniformly.

A hot air supply chamber 48 is disposed near the roller 42 inside the drying section main body 34A, with the film 14 conveyance path interposed therebetween. The longitudinal direction of the hot air supply chamber 48 (L direction shown in FIG. 5) is along the width direction of the film 14, and the longitudinal dimension of the hot air supply chamber 48 is larger than the width direction dimension of the film 14. ing. As shown in FIG. 5, each hot air supply chamber 48 is provided with an opening 48B at one end in the longitudinal direction of the base 48A, and hot air generated by a fan 60 and a heater, which will be described later, is supplied from this opening 48B. is being supplied. A pair of warm air discharge portions 50 are attached to the base 48A of the hot air supply chamber 48 and extend along the longitudinal direction of the base 48A.

[0022] These warm air discharge portions 50 are hollow inside and communicated with the base portion 48A. As shown in FIG. 1, the hot air discharge ports 52 and 53 are each provided so as to be biased toward one end in the width direction of the hot air discharge portion 50, and the other end in the width direction is formed in an arc shape. 50A and 50B. That is, the hot air discharge section 50 on the upstream side of the conveyance path of the film 14
has a warm air outlet 53 on the upstream side and an arcuate portion 5 on the downstream side.
0B is formed. The hot air discharge section 50 on the downstream side includes:
A warm air discharge port 52 is formed on the downstream side, and an arcuate portion 50A is formed on the upstream side. As a result, the warm air supplied into the hot air supply chamber 48 is guided to the tip of the hot air discharge section 50, and is connected to the biased hot air discharge ports 52, 53 and the arcuate portions 50A, 50.
B along the transport path of the film 14 in the upstream direction (
The liquid is discharged in the direction of arrow B in FIG. 1) and in the downstream direction (direction of arrow A in FIG. 1).

Furthermore, as shown in FIG. 5, the base portion 48A is
The width dimension (the dimension in the W direction shown in FIG. 5) from one end where the opening 48B is provided to the other end is gradually reduced. As a result, the amount of hot air discharged from the hot air discharge ports 52 and 53 is uniform from one end to the other end in the longitudinal direction of the hot air discharge section 50.

Furthermore, as shown in FIG.
, 53 between the centers where the hot air hits the surface of the film 14 is defined as a dimension P1. The interval at which the hot air discharged from the warm air discharge port 52 and the hot air discharge port 53 of the downstream hot air supply chamber 48 hits the surface of the film 14 is defined as a dimension P2. The interval dimension P1 and the interval dimension P2 are such that the interval dimension P1 is wider than the interval dimension P2. As a result, the intervals at which hot air is blown onto the film 14 differ between the rollers.

Furthermore, as shown in FIGS. 1 and 5, the base 4
8A has a hot air discharge part 50 between two hot air discharge parts 50.
A discharge hole 54 is provided that penetrates from the surface where the base 48A is attached to the opposite surface.
The opening is formed in an oval shape and extends along the longitudinal direction. As shown in FIG.
in the direction opposite to the transport path of the film 14 (arrow C in FIG. 1).
direction). Furthermore, a discharge path 49 is opened between the adjacent warm air supply chambers 48 from the film transport path to the opposite side of the film 14 transport path of the hot air supply chamber 48 . The opening of this discharge path 49 when viewed from the film 14 side extends along the longitudinal direction of the hot air supply chamber 48 into the drying device main body 3.
It spans both sides of 4A. After the hot air blown onto the film 14 dries the film 14, the film 1
The paper can be discharged in the direction opposite to the transport path No. 4 (direction of arrow D in FIG. 1).

On the other hand, as shown in FIGS. 2 and 3, an exhaust port 56 is provided at the bottom of the drying section main body 34A, and one end of the return duct 58 corresponds to the exhaust port 56 of the drying section main body 34A. attached. Return duct 58
The other end is connected to the intake side of the fan 60. Furthermore, an intake duct 62 that communicates with the aircraft body 10A is connected to the intermediate portion of the return duct 58.

Further, the drying section main body 34A is provided with an exhaust duct 61 for discharging high-humidity air after the film 14 in the drying section main body 34A has been dried. The hot air blown onto the film 14 through the hot air discharge ports 52 and 53 is discharged from near the surface of the film 14, becomes an air flow toward the lower part of the drying section main body 34A, and is discharged from the exhaust duct 61 to the outside of the body 10A. Ru. In addition, the drying section main body 34A
A part of the airflow heading toward the bottom is taken into the airframe 1 from the intake duct 62 via the exhaust port 56 and the return duct 58.
It is guided to the intake side of the fan 60 together with the air outside 0A.

Here, the air guided to the intake side of the fan 60 is determined by the cross-sectional area of the return duct 58 and the intake duct 6.
According to the ratio of the flow path cross-sectional area of 2, the proportion of air flowing from the drying section main body 34A is about 80%, and the proportion of air flowing from outside the body 10A is about 20%.

As shown in FIG. 4, on the exhaust side of the fan 60, there is a heater box 64 in which a heater (not shown) is disposed.
One end of the is attached. The heater box 64 is bent at a right angle at the center. The air guided to the intake side of the fan 60 is sent out as an air stream from the exhaust side by the fan 60, heated by the heater in the heater box 64, and sent out from the heater box 64 as warm air.

At the other end of the heater box 64 is a duct 6.
6 is installed. The side surface of the duct 66 is attached to the side surface of the drying section main body 34A along the conveying direction of the film 14, and is shown in the figure corresponding to each opening 48B of the hot air supply chamber 48 arranged as shown in FIG. No openings are provided. Thereby, the duct 66 and each warm air supply chamber 48 are communicated with each other, and the warm air sent out from the heater box 64 is supplied to each hot air supply chamber 48. Also,
As shown in FIG. 4, the flow passage cross-sectional area of the duct 66 is
6, that is, along the conveyance direction of the film 14, the size is gradually reduced toward the upstream side. As a result, each hot air supply chamber 4 is branched from the duct 66.
The flow rate of the hot air supplied to the tubes 8 per unit time is approximately uniform.

Next, the operation of this embodiment will be explained. In the automatic developing machine 10 shown in FIG. 2, a film 14 with an image exposed thereon, which is inserted through a carry-in port 12, is developed, fixed, and washed with water, and then squeezed by a pair of rollers 32. It is fed into the drying section main body 34A.

Inside the drying section main body 34A, the film 14 is conveyed downward by the roller 42, and the film 14 is dried by being blown with warm air discharged from the hot air discharge ports 52 and 53 of the hot air discharge section 50. At this time, the hot air discharged from the hot air discharge ports 52 and 53 is moved in the direction of the arrow A in FIG. The arcuate portion 50B discharges the liquid in the direction of the arrow B in FIG. 1, and the liquid is blown onto the surface of the film 14, thereby drying the film 14.

The highly humid air that dries the film 14 flows from the surface of the film 14 to the adjacent hot air supply chamber 48.
film 1 from between this hot air supply chamber 48.
It is discharged to the opposite side to the conveyance path No. 4 (indicated by arrow D in Figure 1).
. Further, a portion of the high-humidity air that has dried the film 14 is also discharged from a discharge hole 54 formed in the hot air supply chamber 48 . Air discharged from the discharge hole 54 formed in the hot air supply chamber 48 is directed from the hot air discharge section 50 toward the roller 42 sandwiched between the two hot air discharge sections of one hot air supply chamber 48. The amount is small because hot air is not being discharged.

As a result, after drying the film 14, the hot air discharged from the hot air discharge section 50 is discharged from the adjacent hot air supply chambers 48 because the space between these hot air supply chambers 48 is open. A large amount is discharged from between the hot air supply chambers 4 and 4.
The amount of air discharged from the discharge hole 54 formed at 8 becomes small, and the highly humid air after drying the film 14 can be efficiently exhausted. With this, film 1
4, there are always warm air discharge ports 52, 5 of the hot air discharge section 50.
It becomes possible to supply dry warm air from 3.

Further, the film 14 transported by the rollers 42 of the drying section main body 34A may have uneven transport speed at the moment the leading edge of the film 14 comes into contact with each roller 42. Since the rollers 42 are arranged at equal intervals, this speed unevenness occurs every time the film 14 moves by a predetermined amount (the distance between the rollers 42). In this embodiment, the hot air discharged from the hot air discharge ports 52 and 53 of the hot air supply chamber 48 is
The spacing dimensions P1 and P2 (see FIG. 1) are different from those sprayed at No. 4. Rollers 42 are arranged at equal intervals,
When speed variations occur in the conveyance speed of the film 14, the same portion of the film 14 appears between the rollers 42, but by varying the blowing interval dimension, it is possible to blow hot air to different portions of the film 14 each time. becomes.

That is, as shown in FIG. 3, when the leading edge of the film 14 being conveyed by the roller 42 comes into contact with the roller 42, when there is unevenness in the conveying speed of the film 14, it is possible to The same part of the film 14 always appears between the rollers 42, and hot air is blown onto a different part of the same part of the film 14 from the hot air discharge unit 50 each time uneven speed occurs. Become. Thereby, uneven drying of the film 14 can be suppressed and the film 14 can be dried substantially uniformly.

The film 14 dried evenly inside the drying section main body 34A in this way is moved to the guide rollers 44, 4.
6, the film is transferred from the transport port 38 to the film receiving box 4.
Exported to 0.

FIG. 6 shows a drying section main body 80A of a drying section 80 according to a second embodiment of the present invention. In the main body 80A of the drying section, hot air supply chambers 82 and 84 are arranged alternately along the transport path of the film 14. Hot air supply room 82
The warm air discharge unit 50 provided in the above is formed with a hot air discharge port 53 and an arcuate portion 50B, and is capable of discharging hot air toward the surface of the film 14, so that the adjacent rollers 42 come into contact with the film 14. Hot air is discharged near the downstream side of the part where the The hot air discharge section 50 of the hot air supply chamber 84 adjacent to the hot air supply chamber 82 includes a hot air discharge port 52 and an arcuate portion 50A.
are formed, and the hot air is discharged to the vicinity of the upstream side of the portion where the adjacent rollers 42 contact the film 14.

In the drying section main body 80A in which the warm air supply chambers 82 and 84 are arranged, the hot air discharged from the hot air discharge ports 52 and 53 of each of the hot air supply chambers 82 and 84 is
Hot air discharged from the discharge holes 54 formed in the hot air supply chambers 82 and 84 and discharged from the other hot air discharge ports 52 and 53 can be discharged from between the hot air supply chambers 82 and 84. As a result, the highly humid air after drying the film 14 can be discharged more efficiently than before.

[0040] Also, the interval between the hot air discharge ports 52 (not shown) or the hot air discharge portions 53 of the hot air supply chambers 82 and 84 is determined by the dimension P3, and the interval between the hot air discharge ports 53 and the hot air discharge ports 53 is Dimension P4 is the interval between blowing between the hot air outlet 52 located downstream of the hot air outlet 52, and dimension P4 is the interval between the hot air blowing outlet 52 and the hot air outlet 53 positioned downstream of the hot air outlet 52. If P5, the interval dimensions P3, P4
, P5 are different from each other. As a result, the roller 42
The film 14 transported by the rollers is blown with hot air to different parts between the rollers, and even if the transport speed of the film 14 is uneven, it is possible to suppress uneven drying of the film 14. .

In this embodiment, the hot air is guided by the biased hot air outlet 52 and the arcuate portion 50A of the hot air outlet 50, but the hot air is guided by the contact area between the roller 42 and the film 14. It is sufficient if the hot air can be blown to the vicinity of the upstream side and the vicinity of the downstream side, for example, a hot air outlet where the hot air outlet is not biased, and a contact area between the roller 42 and the film 14 to blow the hot air discharged from the hot air outlet. It may be constructed by a current plate that guides the flow to the vicinity of the upstream side and the vicinity of the downstream side.

Furthermore, in this embodiment, an example in which six hot air supply chambers 48 are provided in the drying section main body 34A has been described, but in the present invention, the hot air is discharged in the direction between the film 14 and the roller 42. There are no restrictions on the shape, number, etc. of the hot air supply chambers, as long as the hot air can be blown to the vicinity of the upstream side and the vicinity of the downstream side of the contact portion.

Furthermore, in this embodiment, hot air is blown near the contact area between the surface of the film 14 and the roller 42, that is, at a desired angle with respect to the film 14 along the conveyance direction when viewed from the width direction of the film 14. The example in which hot air is discharged has been described, but when viewed from the conveying direction of the film 14, the hot air discharge direction is in the width direction of the film 14.
It may or may not be orthogonal to the surface of 4.

[0044]

Effects of the Invention As explained above, in the present invention, even if a large amount of hot air is blown onto a photosensitive material, highly humid air can be efficiently discharged, the photosensitive material can be dried in a short time, and a photosensitive material with a good finish can be obtained. Drying equipment can be obtained.
