  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 shows a crease forming device 10 according to an embodiment of the present invention. In the figure, the left side is the upstream and the right side is the downstream. From the upstream side, the photographic paper P to which a photograph is attached using silver salt photographic development or the like is turned upside down, and a crease forming device for each sheet. 10 is supplied. Here, a direction parallel to the paper surface of the photographic paper and perpendicular to the conveyance direction of the photographic paper is defined as the width direction. The side of the photographic paper on which the photograph is attached is the front surface, and the side on which the photograph is not attached is the back surface.

  The folding line forming apparatus 10 is roughly divided into a carrying-in unit 12 for carrying in photographic paper, a positioning unit 14 for stopping and positioning the photographic paper, and a rotary processing apparatus for forming a folding line with respect to the positioned photographic paper. 16 and a carry-out unit 18 for carrying out the photographic paper on which the crease is formed.

  The carry-in unit 12 can be configured by an arbitrary conveying unit that conveys the photographic paper almost horizontally with the surface of the photographic paper facing upward. For example, the carrying unit 122 and a pressing unit that presses the photographic paper on the feeding belt 122. 124 and drive means 126 for driving the feed belt 122. The driving means 126 is intermittently driven so as to feed the photographic paper to the rotary processing device 16 at substantially constant time intervals.

  The positioning unit 14 is provided in the unloading unit 18 on the downstream side of the rotary processing device 16 and includes a plurality of stoppers 142 and a driving unit 144 for moving the stoppers 142 up and down. The plurality of stoppers 142 are aligned at intervals in the width direction of the photographic paper (see FIG. 3), and can be moved up and down in synchronization with the intermittent operation to appear in and out of the conveyance surface of the carry-out unit 18. ing. When the stopper 142 protrudes from the conveying surface of the carry-out portion 18, it comes into contact with one side on the downstream side of the photographic paper.

  As shown in FIG. 2, the rotary processing device 16 mainly includes a cutter roll 162 and an anvil roll 164 facing the cutter roll 162, and the photographic paper passes between these rolls 162 and 164. It is supposed to be. The cutter roll 162 and the anvil roll 164 are coupled to the driving means 165 via a transmission mechanism, and the driving force from the driving means 165 is transmitted to both rolls.

  The cutter roll 162 is provided with a blade portion 166 extending in the width direction of the photographic paper. Here, the cutter roll 162 can be composed of a magnet cylinder and a flexible die, and the flexible die can be wound around the magnet cylinder using magnetic force. However, the blade portion 166 can be directly formed on the cutter roll 162 without using a flexible die and a magnet cylinder.

  Specifically, as shown in FIG. 3 (b), the blade portion 166 includes a cut portion 166a in which the blade is formed and an uncut portion 166b in which the blade is missing in the width direction, and the cut portion 166a The uncut portions 166b are alternately arranged. When the blade portion 166 bites into the photographic paper P, a cut portion P1 corresponding to the cut portion 166a of the blade portion 166 as shown in FIG. 4B and an uncut portion P2 corresponding to the uncut portion 166b. Are formed in the width direction of the photographic paper P. As an intermittent cut, if the length in the width direction of one cut portion P1 is L1, and the length in the width direction of one uncut portion P2 is L2, then L1 and L2 have the same order length. It is preferable that L1 / L2 = 0.5 to 1.5. Specifically, L1 can be about 0.2 mm and L2 can be about 0.15 mm. L1 or L2 can be 0.5 to 1.5 times the thickness d of the photographic paper.

  In the cut part 166a, as shown in FIG.3 (c) and FIG.4 (c), the blade angle of the blade part 166 becomes a sharp angle of about 40 degrees-45 degrees, and, thereby, a cut part P1 is a substantially V-shaped groove having a sharp angle of about 40 ° to 45 °. This blade angle is smaller than the blade angle (50 to 60 °) of a blade that performs processing on ordinary long paper. For this reason, the front dimension of the groove can be reduced.

  In the rotary processing device 16, the blade portion 166 bites into the printing paper halfway through its thickness. In other words, the blade portion 166 does not penetrate the printing paper. Preferably, the depth of penetration of the blade portion 166 into the photographic paper is such that the depth of the groove of the cut portion P1 formed by the blade portion 166 is about 30 to 60% of the thickness of the photographic paper. Is controlled.

  The carry-out unit 18 can be configured by an arbitrary conveyance unit that conveys the photographic paper almost horizontally with the surface of the photographic paper facing up, like the carry-in unit 12. For example, the carry-out unit 18 moves between the plurality of stoppers 142. A plurality of feed belts 182, presser means 184 for pressing the photographic paper on the feed belt 182, and drive means 186 are provided. The driving means 186 is driven intermittently.

  A photographic paper supply unit 30 can be provided on the upstream side of the folding line forming apparatus 10. The photographic paper supply unit 30 includes a storage unit 32 that stacks and stores one or more photographic papers, a feed roll 34, and a driving unit that drives them. The storage unit 32 sequentially rises in accordance with the number of photographic papers stacked, and the photographic paper at the uppermost position always comes into contact with the feed roll 34 to bring the photographic paper into the carry-in part of the crease forming device 10. 12 can be sent out.

  A folding device 40 can be provided on the downstream side of the folding line forming device 10. The folding device 40 includes two sandwiching roll pairs 42 and 44 for folding, a stopper 46 that comes into contact with one side on the downstream side of the photographic paper, and driving means for driving the roll. When the photographic paper carried out from the carry-out portion 18 passes through the sandwiching roll pair 42 and is stopped by the stopper 46, the photographic paper is folded and folded at the crease formed by the crease forming device 10. In this state, it passes through the sandwiching roll pair 44 and is discharged to the receiving portion 48.

  The processing procedure will be described using the crease forming apparatus 10 configured as described above.

  First, as described above, the photographic paper loaded in the storage unit 32 of the photographic paper supply unit 30 is sent out to the carry-in unit 12 of the folding line forming apparatus 10 one by one by the delivery roll 34. The carry-in unit 12 conveys the downstream side of the photographic paper until it passes through the rotary processing device 16 and comes into contact with the plurality of stoppers 142 of the positioning unit 14. At this time, the plurality of stoppers 142 of the positioning unit 14 protrude upward from the conveyance surface (see the phantom line in FIG. 3A) and contact with one side on the downstream side of the photographic paper. Is positioned so that one side thereof is perpendicular to the conveying direction. Therefore, even if the photographic paper is inclined with respect to the transport direction, the inclination is corrected by the stopper 142.

  The photographic paper positioned by the stopper 142 has a central portion in the conveyance direction positioned between the cutter roll 162 and the anvil roll 164 of the rotary processing device 16, and these rolls 162 and 164 rotate to cause the blade portion 166 to move. A cut is formed in the width direction of the photographic paper by cutting into the back surface of the photographic paper and forming a crease.

  When the rolls 162 and 164 are rotated, the stopper 142 is retracted from the conveyance surface (see the solid line in FIG. 3A), and the feed belt 122 and the pressing means 124 of the carry-in unit 12 and the feed belt of the carry-out unit 18 are used. Although the photographic paper is gently pressed by the 182 and the pressing means 184, the photographic paper is not completely restrained in this state, and when the rolls 162 and 164 are rotated and the blade portion 166 is caught, It is possible to cope with the rotation of the blade 166 by slightly moving.

  After the blade part 166 bites into the photographic paper, the carry-out part 18 starts conveyance. At this time, there is a concern that the blade part biting into the photographic paper generally cannot be removed, and in particular, the concern is further increased when the blade angle of the blade part 166 is small. However, in the present invention, the photographic paper is completely removed. The unconstrained and the blade portion 166 is composed of a cut portion 166a and an uncut portion 166b, and only the cut portion 166a bites into the photographic paper, and the cut portion 166a is relatively flexible. Therefore, the blade portion 166 and the photographic paper are smoothly separated.

  In this way, it becomes possible to make the cut by the blade portion 166 and the carry-out operation by the carry-out portion 18 almost continuous without damaging the photographic paper, so that the work can be made more efficient.

  The photographic paper carried out by the carry-out unit 18 passes through the pair of sandwiching rolls 42 and 44 in the downstream folding device 40 as described above, and is folded along the folding line with the surface with the photograph attached inside. Be turned. At this time, the V-shaped groove of the cut portion P1 spreads to form a folded outer contour. Further, the uncut portion P2 is folded following the adjacent cut portion P1 (see FIG. 5A).

  The photographic paper folded in this way is subjected to further processing. The further processing is an operation of applying an adhesive on the back surface, laminating them, and binding to an album as shown in FIG.

  By making the fold line as described above into intermittent cuts, it is possible to fold sharply, that is, thinly, as compared with the case where the fold line is provided without forming the cut line (see FIG. 5B). it can. Unlike normal paper, photographic paper is thick and stiff, so it is difficult to fold sharply. However, according to the present invention, it is possible to fold sharply. The back can be finished with a beautiful finish. Also, photographic paper has the property of causing discoloration at the crease, but if the crease part is thick, the discoloration part becomes large and looks bad, but according to the present invention, it folds sharply. Therefore, the discolored portion can be reduced and the appearance can be improved.

  In addition, since there is an uncut portion P2 as compared with the case of forming continuous cuts, the degree of freedom in the cuts of the photographic paper is small, and it is possible to prevent the cuts from spreading more than necessary when folded. Can be folded along the crease correctly. Moreover, since the blade angle is small, the groove size of the groove of the cut portion P1 is small, and the effect is further obtained. On the other hand, in the case of continuous cuts, since the degree of freedom of the cuts is high and spreads easily, even if folded along the fold line, there is a possibility of causing a folding shift as shown in FIG. According to this, such folding can be prevented.

  In addition, if the cut is a continuous cut, there is a risk that the cut will be caught by the claw-like member of the device in the subsequent processing, and when a damaged part occurs in a part of the cut, the damage is generated from there. There is a risk of progressing in the width direction and developing into cracking, turning, peeling, and separation. On the other hand, according to the present invention, since the cuts are intermittent, it is difficult to catch, and even if damage occurs in a part of the cut portion, the progress of damage can be prevented. Therefore, compared with the case of forming continuous cuts, the fold formed based on the intermittent cuts of the present invention can improve the appearance, and the back portion is in a bound state in the bound state. Even if it is difficult to damage and the page is repeatedly turned, the strength of the crease portion is high, so that the durability can be improved.
