Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] 1. Field of the Invention [0002] The present invention relates to a photosensitive material transport method for transporting a photosensitive material by a transport roller to a next step or the like and a structure of a photosensitive material transport system.

[0002]

2. Description of the Related Art Generally, when processing photosensitive materials,
A plurality of pairs of transport rollers are provided, the photosensitive material is sandwiched between the transport rollers, and a transport force is applied to feed the photosensitive material to the next process or the like (roller transport type).

In recent years, for the purpose of rapid processing, it has been considered that two or more rows of sheet-shaped photosensitive material cut to a predetermined size are simultaneously conveyed and each step is simultaneously processed. The rollers are arranged so as to straddle a plurality of rows. In this multi-row conveyance, when processing an extremely wide photosensitive material, it can be conveyed so as to straddle a plurality of rows, eliminating the need for a dedicated machine as in the conventional case, and having excellent versatility. It can be called a device.

By the way, in the case of photosensitive material, for example, photographic paper,
A prescribed size is determined, and the paper is generally conveyed so that its length and width are parallel and perpendicular to the conveyance direction, respectively. In addition, processing of a photosensitive material having a wide width extending over a plurality of rows as described above is not frequently performed.

[0005]

In such a situation,
When processing a wide photosensitive material that extends over the plurality of rows, the photosensitive material comes into contact with a part that is not normally used, which is a boundary between the transport paths of the transport rollers, and dirt is transferred to the photosensitive material. In some cases, the quality was impaired.

[0006] For this reason, it has been proposed that the photosensitive material is periodically moved to a position straddling two rows so as not to deposit dirt on the conveying roller. In this case, it is not preferable because the subsequent processing (eg, sorting) is greatly affected.

In view of the above facts, the present invention eliminates the difference in the frequency of use of the conveying roller without performing any special control, thereby preventing the accumulation of dirt on the conveying roller. It is an object of the present invention to provide a photosensitive material transporting method and a photosensitive material transporting system that can prevent the transfer of the photosensitive material.

[0008]

According to the first aspect of the present invention, there is provided a photosensitive material transporting apparatus comprising a transport roller for nipping and transporting a sheet-like photosensitive material transported in a plurality of rows so as to straddle the plurality of rows. The system is characterized in that the photosensitive material is obliquely oriented with respect to the transport direction such that an overlapping portion occurs in the trajectories of the photosensitive materials transported on the adjacent transport paths.

According to the first aspect of the present invention, when the photosensitive material is transported in a plurality of rows, the photosensitive material is usually transported so that the vertical and horizontal sides thereof are parallel and perpendicular to the transport direction, respectively. There is a portion where the photosensitive material is not nipped (contacted) by the transport rollers between the materials. However, in the first aspect, since the photosensitive material is transported in an oblique direction, the ends of the adjacent photosensitive materials are transported along the same locus, and the photosensitive material is sandwiched over the entire area of the transport roller. As a result, even when a wide photosensitive material is transported across a plurality of rows, which is a very small amount of processing, there is no accumulation of dirt on the transport rollers, and the dirt is transferred to the photosensitive material. Can be prevented.

According to a second aspect of the present invention, a conveying roller for conveying the sheet-like photosensitive material conveyed in a plurality of rows is disposed so as to straddle the plurality of rows of the sheet-like photosensitive material. When the photosensitive material is delivered to the transport roller, the photosensitive material is caused to enter at a predetermined angle with respect to the transport direction, and the photosensitive material is transported in parallel with the transport roller while maintaining the angle at which the photosensitive material entered. In addition, a superimposed portion is formed on the path of passage of the photosensitive material conveyed in each of the adjacent rows.

According to the second aspect of the present invention, the transport rollers are disposed so as to straddle a plurality of rows. The vehicle enters at a predetermined angle with respect to the transport direction (transport path) of the transport rollers. For this reason, the vertical and horizontal sides of the photosensitive material are held between the transport rollers while being inclined with respect to the transport direction. As a result, the transport width dimension is enlarged (the vertex of the photosensitive material shifts in a direction orthogonal to the transport direction), and the ends of the adjacent photosensitive material overlap the same portion of the transport roller. As a result, even if a very small amount of photosensitive material is conveyed across a plurality of rows, no dirt is deposited on the conveying rollers, and the dirt is transferred to the photosensitive material. can do.

On the downstream side of B, two pairs of rollers 18 and 20 are provided, respectively, so that the photographic paper 16 pulled out from the outlets 12A and 14A is nipped and transported substantially horizontally. Further, a sensor 22 is provided downstream of the roller pair 18 disposed near the magazines 12 and 14, and detects the presence or absence of the photographic paper 16. In the present embodiment, the printing paper 16 is pulled out from one magazine 12 and processed, and when all the printing paper 16 of this magazine 12 is used up, the printing paper 16 of the other magazine 14 is used. , The sensor 22 detects the end of the photographic paper 16 in the magazine 12 or 14. The magazines 12 and 14 can store photographic papers 16 of different widths and types as needed, and can switch and use them as needed.

A cutter section 24 is provided near the downstream side of the downstream roller pair. The cutter unit 24 is provided with a sensor 26, which corresponds to the cutting position. For this reason, by cutting the photographic paper 16 when a predetermined time has elapsed after the leading end of the photographic paper 16 cut by the cutter unit 24 starts to be conveyed, a sheet having a length corresponding to the predetermined time is obtained. Will be.

The photographic paper conveyed from the cutter unit 24 is nipped by a pair of rollers 28. The upper roller 28 </ b> A of the roller pair 28 is rotatably supported on one side in the longitudinal direction of a rectangular plate-shaped bracket 30. On the other side of the bracket 30, the rotation shaft of the lower roller 28B of the roller pair 28 is supported.

Further, the roller pair 28 is bridged between leg plates of a substantially U-shaped bracket 32 having a pair of leg plates. The rotation shaft of the upper roller 28A is accommodated in an arc-shaped long hole 32A provided in the leg plate. For this reason, the upper roller 28A has a structure in which the bracket 30 can rotate and move along the arc-shaped long hole while maintaining the interval with the lower roller 28B.

Here, the first position is when the upper roller 28A comes directly above the lower roller 28B (see the solid line position in FIG. 1), and the photographic paper 16 conveyed from the cutter unit 24 is referred to as the first position. And the position to receive it. Also, the upper roller 28
When A comes to the right end of the arc-shaped long hole 32A, the second position is set (refer to the chain line position in FIG. 1). The position to be sent out from the rear end side of the temporary storage section 34 to the temporary storage section 34.

The bracket 32 has a movable bracket 36 attached to the back of the base. The moving bracket 36 has a substantially L-shape, and a horizontal lower portion is fixed to the moving block 40 of the ball screw mechanism 38.
For this reason, by rotating the shaft (screw portion) of the ball screw mechanism 38, the roller pair 28 supported by the bracket 32 can be moved to one of a plurality of rows (two rows in the present embodiment) of the transport path shown in FIG. (Refer to the position (A) or (B)) (distribution of the printing paper 16).

The temporary accommodating portion 34 is provided with the two roller pairs 1
It is arranged above 8,20. The roller pair 28 that has received the printing paper 16 at the first position from the cutter unit 24 moves to the second position, and the printing paper 16 is guided by the guide plate 44 and is conveyed to the entrance 34A of the temporary storage unit 34. It has become so.

As shown in FIGS. 1, 3 and 4, the temporary storage section 34 is constituted by two pairs of belts 46 and 48, and the lower belt 48 has two rollers 50, 5 and 5.
It is wrapped around 2. The upper belt conveyor 46 is wound around three rollers 54, 56, 58.

The roller 54 for supporting the upper belt 46 on the right side in FIG. 1 has its rotating shaft pivotally supported on one longitudinal side of a rectangular plate-shaped bracket 60. On the other side of the bracket 60, a rotating shaft of a roller 50 that supports the lower belt 48 on the right side in FIG. 1 is supported.

Further, the rollers 54 and 50 are stretched between leg plates of a substantially U-shaped bracket 62 having a pair of leg plates. The rotation shaft of the upper roller 54 is housed in an arc-shaped long hole 62A provided in the leg plate.
For this reason, the upper roller 54 has a structure in which the bracket 60 can rotate and move along the arc-shaped long hole 62A while maintaining the interval with the lower roller 50.

Here, the first position is when the upper roller 54 comes to the right end of the arc-shaped long hole 62A (see the solid line position in FIG. 1), and the printing carried from the roller pair 28 is performed. The position for receiving the paper 16 is set. At this time, the belts 46 and 48 sandwich the printing paper 16 and the belts 46 and 48
The printing paper 16 is sandwiched between them. Here, the time for holding the photographic paper 16 at the entrance 34A of the temporary storage portion 34 and for carrying the paper after the reverse rotation of the roller pair 28 starts is fixed.

The photographic paper 16 has one row of belts 46, 48.
When it is recognized that the belt 4 has been nipped,
The photographic paper 16 is also sandwiched between the photographic papers 6 and 48.
Is transported. Therefore, the printing paper 1
6 is transported, and two rows of transport paths (here, belts 46, 4
8), the sheet-shaped photographic paper 16 is arranged.

Here, the upper roller 54 is formed in the shape of an arc-shaped long hole 6.
The position at the left end of 2A is defined as the second position (see the dashed line position in FIG. 1), and the photographic paper 16 received from the roller pair 28 is sent out to the exposure stage 78 to be described later by the reverse conveyance of the belts 46 and 48. Position. At the time of feeding, the rear end of the printing paper 16 is always at the same position.

In the exposure stage 78, the photographic paper 16 conveyed from the temporary storage section 34 is nipped by a pair of rollers 80A provided at the entrance. The roller pair 80
A and the conveying linear speed of the belts 46 and 48 are preferably the same, but by equipping each roller around which the belts 46 and 48 are wound with a one-way clutch, the conveying linear speed of the roller pair 80A can be reduced. , 48 may be faster.

The exposure stage 78 has a single exposure unit 104A corresponding to each transport path. The exposure unit 104A applied in the present embodiment is a so-called scanning exposure system, and its schematic configuration is as shown in FIG.
A slit 104D is provided in a direction orthogonal to the conveyance path by two pairs of rollers 104B and 104C, and the laser beam is scanned along the slit 104D (main scanning). The main scanning by the laser beam has a scanning width for simultaneously scanning two rows of photographic paper. The photographic paper 16 is transported at a constant speed, and this transport is a sub-scan.

For image recording using a laser beam, it is possible to use a general exposure system that deflects light emitted from the semiconductor laser 104G in the main scanning direction by the polygon mirror 104E and corrects aberrations and the like by the fθ lens 104F. .

The exposure stage 78 is not limited to the above-described scanning exposure system, and performs surface exposure of transmitted light from a negative film.
It may be so-called analog exposure.

Photographic paper 1 after printing process (scanning exposure)
6 is conveyed by two rollers at the same time while being nipped and conveyed by the pair of rollers 80B on the exit side, and is placed on conveyance belts 110 and 112 (see FIG. 11) disposed downstream of the exposure stage 78. ing.

As shown in FIG.
0 and 112 are provided for each row, and in the present embodiment, two transport belts 110 and 112 are arranged in parallel. Conveying belts 110 and 112 are wound around a single roller 114 disposed at the end of the exposure stage 78 on the side of the two rows of conveying paths. The downstream side of the conveyor bells 110 and 112 is connected to the conveyor belt 1.
The direction of the predetermined angle is changed with respect to the transfer direction by the transfer rollers 10 and 112 (see points A and B in FIG. 11), and a plurality of pairs of transfer rollers 116 (4 in FIG.
The main belts are arranged, and if necessary, 116A, 116B, 116C, 116
D). These transport rollers 11
Reference numeral 6 has a role of nipping and transporting the photographic paper 16 delivered from the transport belts 110 and 112 and sending the photographic paper 16 to a developing process which is the next process.

Here, since the photographic paper transport direction by the transport belts 110 and 112 and the photographic paper transport direction by the transport rollers 116 have a predetermined angle, one of the transport belts (in this embodiment, FIG. Upper conveyor belt 11
The transport length according to 0) is short. As a result, the upper left corners of the transport belts 110 and 112 are approaching the transport rollers 116A closest to the transport belts 110 and 112 (hereinafter, referred to as first transport rollers 116A). To take such a structure, the transport belts 110, 1
Rollers 118 and 120 around the other end of the roller 12
Are located at different positions.

The rollers 114, 118, and 120 have both ends supported by brackets 122, 124, and 126, respectively, and serve as a roller 114 (the roller closest to the exposure stage 78) common to the two conveyor belts 110 and 112. Is connected to a driving unit (not shown), and the transport belts 110 and 112 receive the driving force by the driving force of the driving unit.

Here, the printing paper 16 discharged from the exposure stage 78 is in two rows, and if the printing paper 16 has the same size, the printing paper 16 (which is always conveyed by the upper conveyance belt 110 in FIG. 11). Hereinafter, the upper photographic paper 16) is first sandwiched between the first transport rollers 116A. At this time, the printing paper 16 (hereinafter referred to as the lower printing paper 1) conveyed by the lower conveying belt 112 in FIG.
6) has not reached the first transport roller 116A, and the transport by the transport belt 112 is continued.

On the other hand, the upper photographic paper 16 receives a transport force from the first transport roller 116A by being nipped by the first transport roller 116A. In this case, since the upper photographic paper 16 is only placed on the transport belt 110, the transport direction is changed, and the upper photographic paper 16 moves in parallel along the transport direction by the transport rollers 116 while sliding on the transport belt 110. Become. During this parallel movement, the lower photographic paper 16 also reaches the first transport roller 116A, the transport direction is changed similarly to the upper photographic paper 16, and the parallel movement is started.

At this time, as shown in FIG. 11, there is a portion where the transport trajectories of the lower end of the upper photographic paper 16 and the upper end of the lower photographic paper overlap (see the hatched portion in FIG. 11). Due to this overlap, the photographic paper 16
There is no region in which is not pinched at all, and the accumulation of dirt on this portion is prevented. Therefore, for example, even if a very wide photographic paper is transported in two rows, the transfer of the dirt to the photographic paper does not occur because there is no accumulation of dirt.

Usually, the conveyor belts 110, 112
And the photographic paper transport speed by nipping the transport rollers 116 may be the same, but the panoramic-size photographic paper is transported by the lower transport belt 112 in FIG. When a normal size (full size) photographic paper is conveyed, the lower photographic paper 16
(Panorama size) is also expected to reach the transport roller 116. For this reason, if the photographic paper transport speed by nipping the transport rollers 116 is made slower than the photographic paper transport speed by the transport belts 110 and 112, the overlap of the photographic paper between the rows can be eliminated, and the slowdown or the overlap always occurs. It is only necessary to determine whether or not to slow down the processing depending on the processing efficiency.

Alternatively, a method for solving the above-mentioned problem by taking a gap in consideration of a combination of sizes to be printed before printing, a method of adjusting the timing of sending from the exposure stage in consideration of the combination of print sizes, There is a method in which a plurality of rows of prints are sent from a row near the direction in which the transport direction is changed so that the transport direction changes.

The operation of the present embodiment will be described below. As shown in FIG. 2, magazines 12 and 14 are loaded corresponding to two rows of transport paths. In the work specification according to the present embodiment, it is not always necessary to load both of them, and it is sufficient that at least one magazine 12 (or 14) is loaded. The other magazine 14 (or 12) may be loaded before the photographic paper 16 runs out. Further, the widths and types of the photographic papers 16 accommodated in the magazines 12 and 14 may not be the same and may be different types. However, the following description shows the flow of processing when the same type of photographic paper 16 has been completed.

The processing procedure will be described with reference to the transport path on which the magazine 12 is loaded.
The roller pair 28 located on the downstream side of the roller 4 is operated by operating the ball screw mechanism 38. The rotation axis of the roller 28A on the upper side of the roller pair 28 is positioned at the left end of the arc-shaped long hole, that is, at the first position. Hereinafter, the procedure for drawing out the photographic paper 16 will be described with reference to FIG. 1 and FIGS. 6 to 9.

In the state where the initial setting is completed, the magazine 1
2 to photographic paper 16 (hereinafter referred to as first photographic paper 16A,
The second, third,.
16C ...). The drawn-out first photographic paper 16 is horizontally conveyed by two pairs of rollers 18 and 20, passes through a cutter unit 24, is pinched by the pair of rollers 28, and hangs down by being supported by the pair of rollers 28 by its own weight. (Refer to the state of FIG. 1).

Here, when it is recognized by the sensor 26 that the sheet has been pulled out by a predetermined amount, the cutter unit 24 operates to cut the first photographic paper 16. After cutting, the roller 28
The rotation axis of A is the right end of the arc-shaped long hole 32A,
To the position. Thereby, the extension direction of the rear end of the first photographic paper 16 is directed toward the temporary storage portion 34 (see the imaginary line in FIG. 1).

Here, the ball screw mechanism 38 is operated, and the roller pair 28 starts moving so as to correspond to the other transport path (the upper transport path in FIG. 2) (see FIG. 6A). After corresponding to the other conveyance path, the printing paper 16 is temporarily stored in the temporary storage unit by the reverse rotation of the roller pair 28,
The completed roller pair 28 returns to the original transport path (the lower side in FIG. 2) (see FIG. 6B).

Returning to the original transport path, the next second photographic paper 1
6B is received (see FIG. 6C), and the second photographic paper 16B is continuously sent to the temporary storage section 34 at the received position (see FIG. 6D). When the delivery to the temporary storage unit 34 is completed, the temporary storage units 34 corresponding to the two rows of transport paths include:
The first and second photographic papers 16A and 16B respectively stand by (see FIG. 7A).

Next, all of the temporary storage units 34 are simultaneously driven in reverse rotation so that the first and second printing paper
6 is sent out toward the exposure stage 78. At the same time,
The next third photographic paper 16C is fed to the roller pair 28 (see FIG. 7B). The third photographic paper 16C received by the roller pair 28 during feeding to the exposure stage 78
Starts the lateral movement to the other transport path side by the operation of the ball screw mechanism 38 (see FIG. 7C).

In the exposure stage 78, when the first and second photographic papers 16A and 16B arrive, an exposure process is performed, but the first photographic paper 16A and the second photographic paper 16B are aligned at the rear ends. Therefore, if the sizes are different, the optical axis position is shifted. However, the exposure stage 78 can be moved along the photographic paper transport direction for each of the exposure units 104A corresponding to each transport path, and the exposure stage 78 is previously illuminated based on the size data of the photographic paper carried into the exposure stage 78. If the axes are set, two parallel photographic papers can be exposed at the same time.

During this exposure processing, the roller pair 2 which has moved laterally
8, the third photographic paper 16C is transferred to the temporary storage section 34 (see FIG. 7D), the roller pair 28 returns to the original transport path (see FIG. 8A), and the next fourth printing paper is transferred. The photographic paper 16D is received (see FIG. 8B), and the fourth photographic paper 16D is sent to the temporary storage section 34 corresponding to the original transport path (FIG. 8).
(C)). When the feeding is completed, the third and fourth photographic papers 16C and 16D stand by in the temporary storage section 34 (see FIG. 8D), and the first and second photographic papers 16A on the exposure stage 78 are provided. , 16B, the third and fourth photographic papers 16C, 16D are sent from the temporary storage unit to the exposure stage 78 at the same time as they are transported to the development processing unit. At the same time, the fifth photographic paper 16E is delivered to the roller pair 28 (see FIG. 9A). The movement of the paper 16E is started so as to correspond to the other transport path (see FIG. 9B). Thereafter, that is, after the sixth photographic paper (not shown), FIG.
The same processing as the operation from (D) is repeated.

By replacing the empty magazine 12 with a new one during the processing in the magazine 14, the magazine can be replaced without stopping the processing, thereby further improving the working efficiency. Can be. Also,
The exchangeable time is determined by the photographic paper 16 in one of the magazines.
Is eliminated, and the operator does not need to constantly monitor, but only has to monitor periodically at a relatively long interval, so that maintenance workability is also improved.

Next, the procedure for transporting the photographic paper discharged from the exposure stage 78 will be described. As shown in FIG. 12A, the photographic paper 16 (upper photographic paper 16 and lower photographic paper 16) discharged from the exposure stage 78 is placed on transport belts 110 and 112, respectively. Conveyor belt 110, 1
12 are driven at the same speed, and the upper photographic paper 16 and the lower photographic paper 16
While being placed on the substrates 10 and 112, they are transported as shown in FIG.

Here, in the case of photographic paper 16 of the same size,
The tip corner of the upper photographic paper 16 is placed first on the first transport roller 11.
6A is contacted (pinched).

When the upper photographic paper 16 is nipped by the first transport roller 116A, the upper photographic paper 16 receives the transport force of the first transport roller 116A and receives a predetermined angle with respect to the transport direction of the transport belts 110 and 112. Changed and transported (Fig. 1
2 (C)). That is, the conveyor belts 110, 1
The transport direction of the photographic paper is changed by shifting from the mode in which the photographic paper is placed and transported on the printer 12 to the mode in which the transport is forcible by pinching. The upper photographic paper 16 sandwiched between the first transport rollers 116A maintains the original transport direction,
The lower photographic paper 16 is conveyed by the conveyance belt 112 during the parallel movement, and the tip corner of the lower photographic paper 16 reaches the first conveyance roller 116A (FIG. 12C).
reference).

Thereafter, like the upper photographic paper 16, the first
, And is conveyed while the conveyance direction is changed.

At this time, as shown in FIG. 11, the transport trajectory overlaps between the upper photographic paper 16 and the lower photographic paper 16 (hatched portion in FIG. 11). By providing such an overlapped portion, the photographic printing paper is sandwiched almost over the entire area of the transport roller 116, so that the photographic printing paper is not touched at all, and a portion where dirt is accumulated can be eliminated. By eliminating the accumulation of dirt, it is possible to maintain the quality without transferring dirt to the photographic paper when a wide photographic paper that is processed while being conveyed over two or more rows is conveyed. it can.

In the present embodiment, the exposure stage 7
The transport system located on the downstream side of No. 8 is provided with a portion where the transport trajectories of a plurality of rows of photographic paper are overlapped. However, the present invention can also be applied to a transport system for delivery between processes and a transport system during processing of each process. . Alternatively, the photographic paper may be conveyed obliquely consistently from immediately after being pulled out of the magazines 12 and 14 until all processes are completed.

In the present embodiment, two magazines 1
The two and 14 can be arranged side by side, and after one magazine becomes empty, the photographic paper 16 stored in the next magazine is used. However, the photographic paper 16 may be pulled out from the magazines 12 and 14 at the same time. Good. In addition, the number of magazines loaded is 1
The number may be one or three or more, and is not limited to the number of transport paths.
