Description

  The present invention relates to a photosensitive material squeeze device that squeezes the surface of a photosensitive material that has been washed with water, and a photosensitive material processing device that includes this photosensitive material squeeze device.

  A photosensitive material such as photographic paper on which an image has been exposed is developed with a processing solution such as a developing solution or a fixing bleaching solution, and then the processing solution is washed away with washing water, followed by drying. As described above, when the photosensitive material is developed, bleach-fixed, washed with water and then dried, the washing water adhering to the surface of the photosensitive material is usually removed (squeezed) before the photosensitive material is dried. Is done.

  By the way, the squeeze portion is generally composed of a plurality of roller pairs, and the photosensitive material is sandwiched and conveyed by these roller pairs, and water droplets adhering to the surface of the photosensitive material are removed by contact. This water droplet contains the remaining processing liquid component, and the processing liquid and other stains adhere to the roller pair. When the adhered stain is transferred to the photosensitive material, the photosensitive material is dried. It causes finishing defects such as unevenness, deposition of processing solution components, and deterioration of image quality due to contamination.

  Therefore, it is necessary to clean the roller pair in order to remove dirt attached to the roller pair. As a cleaning method, Patent Document 1 discloses a technique in which the lower peripheral portion of one roller constituting a roller pair is always immersed in cleaning water, and dirt attached to the roller outer peripheral surface is washed away by rotation.

  However, in the technique described in Patent Document 1, since the roller is always immersed in the cleaning water, even if the cleaning water is scraped off from the roller, the roller contains a considerable amount of cleaning water. Therefore, sufficient squeezing cannot be performed on the photosensitive material.

In view of this, it is conceivable to wash away dirt adhering to the roller by spraying cleaning water onto the roller pair at a predetermined timing instead of immersing the roller pair. The density of dirt on the roller depends on the position of the roller. Since they are different, it is required to spray cleaning water for efficiently cleaning the roller.

  The present invention has been made in consideration of the above-described facts, and a photosensitive material squeeze device capable of efficiently cleaning a squeeze means with sprayed cleaning liquid and the photosensitive material squeeze device. An object of the present invention is to provide a photosensitive material processing apparatus provided.

  In order to solve the above problems, the photosensitive material squeeze device according to claim 1 transports the washed photosensitive material toward the drying unit and removes water adhering to the surface of the photosensitive material by contact. And cleaning means for injecting cleaning liquid from a plurality of cleaning liquid injection ports formed side by side in the width direction of the photosensitive material to the squeeze means.

  The squeeze means of the photosensitive material squeeze device according to the first aspect conveys the photosensitive material after the washing process toward the drying unit and removes water adhering to the surface of the photosensitive material by contact. The squeeze means is contaminated by the photosensitive material that comes into contact with the squeeze means, but the dirt tends to concentrate on the outer end portion including the vicinity of the end of the contact area of the squeeze means with the photosensitive material. Therefore, the cleaning liquid injection port formed in the outer end portion is made denser than the other portions. Thereby, the part where the dirt is concentrated can be cleaned intensively, and the squeeze means can be cleaned efficiently.

  In the photosensitive material squeeze device according to the present invention, the sprayed cleaning liquid is directly applied between the cleaning means and the squeeze means, and the applied cleaning liquid is diffused to diffuse the applied cleaning liquid. A guide member having a shape that can be supplied to the squeeze means is provided.

  In this way, the cleaning liquid can be supplied to a wider area of the squeeze means by applying the cleaning liquid to the guide member once, diffusing and supplying it to the squeeze means.

  The photosensitive material squeeze device according to the present invention includes an upstream squeeze unit that is provided upstream of the squeeze unit in the transport direction and removes water adhering to the surface of the photosensitive material by contact. And an upstream side cleaning unit that jets the cleaning liquid to the upstream side squeeze unit from a plurality of cleaning liquid spray ports formed side by side in the width direction of the photosensitive material.

  Thus, by providing the upstream squeeze means upstream of the transport path, squeeze can be performed a plurality of times, and more moisture can be removed until the photosensitive material reaches the drying section.

  The photosensitive material squeeze device according to the present invention is characterized in that, as described in claim 4, the cleaning liquid injection ports of the upstream side cleaning means are formed at equal intervals in the width direction of the photosensitive material. You can also.

  The photosensitive material passing through the upstream squeeze means has more water adhering than when passing through the squeeze means arranged on the downstream side thereof, and dirt adheres to the upstream squeeze means. There is little concentration near the edge.

  Therefore, as described above, the cleaning nozzles are formed at equal intervals in the upstream cleaning unit. Thereby, the whole upstream squeeze means can be washed uniformly.

  In the photosensitive material squeeze device according to the present invention, the number of cleaning liquid injection ports formed in the cleaning unit is set to be larger than the number of cleaning injection ports formed in the upstream side cleaning unit. It can also be characterized as more.

  When a plurality of squeeze means are provided on the transport path, the squeeze means on the downstream side squeeze while transporting the photosensitive material squeezed by the upstream squeeze means. Therefore, the squeeze means is less wet than the upstream squeeze means. Therefore, the dirt is concentrated as compared with the upstream squeeze means. Therefore, in the photosensitive material squeeze device of the present invention, a larger number of cleaning injection ports are formed in the cleaning means arranged on the downstream side than in the upstream cleaning means. As a result, the squeeze means in which dirt is concentrated can be more carefully cleaned than the upstream squeeze means, and the upstream squeeze means and the squeeze means can be efficiently cleaned.

  The photosensitive material squeeze device according to claim 6, wherein the photosensitive material squeezed apparatus transports the washed photosensitive material toward the drying unit and removes water adhering to the surface of the photosensitive material by contact; and the upstream side A downstream squeeze unit that is provided downstream of the squeeze unit in the transport direction and removes water adhering to the surface of the photosensitive material that has passed through the upstream squeeze unit by contact, and an upstream that jets a cleaning liquid to the upstream squeeze unit Side cleaning means and downstream cleaning for injecting cleaning liquid to the downstream squeeze means from cleaning injection ports formed in a larger number than the cleaning injection ports formed in the upstream side cleaning means arranged in the width direction of the photosensitive material Means.

  The upstream squeeze means of the photosensitive material squeeze device according to claim 6 conveys the photosensitive material after the washing process toward the drying unit and removes water adhering to the surface of the photosensitive material by contact. The downstream squeeze means is provided on the downstream side in the transport direction with respect to the upstream squeeze means, and removes water adhering to the surface of the photosensitive material via the upstream squeeze means by contact. The downstream squeeze means squeezes while transporting the photosensitive material squeezed by the upstream squeeze means, so that it is less wet than the upstream squeeze means. Therefore, the dirt is concentrated as compared with the upstream squeeze means. Therefore, in the photosensitive material squeeze device of the present invention, a larger number of cleaning injection ports are formed in the cleaning means arranged on the downstream side than in the upstream cleaning means. Thereby, the downstream squeeze means having a thickened dirt can be cleaned more carefully than the upstream squeeze means, and the upstream squeeze means and the downstream squeeze means can be efficiently cleaned.

  A photosensitive material processing apparatus according to a seventh aspect includes the photosensitive material squeeze apparatus according to any one of the first to sixth aspects.

  According to the light-sensitive material processing apparatus of the present invention, the portion of the squeeze means where the stain is concentrated and the portion where the stain is concentrated are more carefully cleaned than the other portions, so that the squeeze means can be efficiently cleaned.

  Since the present invention has the above-described configuration, the cleaning liquid can be efficiently sprayed to clean the squeeze means with dirt.

  First, a schematic configuration of the printer processor 10 embodying the present invention will be described.

  As shown in FIG. 1, the printer processor 10 includes an image input device 12, an image processing device 13, a printer 15, and a processor 16. Each unit constituting the printer processor 10 is connected to the control unit 17 via a wiring (not shown), and the operation of the entire printer processor 10 is controlled by the control unit 17.

  The image input device 12 generates image data by photoelectrically reading the projection light of an image recorded on a photographic film using an image sensor such as a CCD image sensor, or recorded on a recording medium such as a memory card. One image data is acquired by reading the image data. This image data is sent to the image processing device 13, and image processing such as color balance correction and density correction is performed. The image data subjected to the image processing is sent to the printer 15 and is used at the time of image recording.

  The printer 15 performs image recording with recording light whose intensity is modulated based on image data while conveying a cut recording paper cut to a predetermined length (hereinafter simply referred to as “recording paper S”). From the upstream side in the direction, a supply unit 20, a back printing unit 22, a registration unit 24, an image recording unit 26, a sub-scanning receiving unit 28, a sorting unit 30, and a carry-out unit 32 are provided. In each part, a plurality of conveyance roller pairs including a driving roller and a nip roller are provided along the conveyance path R of the recording paper S.

  In the supply unit 20, magazines 20a and 20b for storing a long photosensitive recording paper 34 attached in a roll shape are set. Each magazine 20 a, 20 b is provided with a pair of drawing rollers 21 a, 21 b for pulling out the photosensitive recording paper 34 and transporting it toward the back printing unit 22. In this embodiment, two magazines 20a and 20b are provided. However, the number of magazines may be one, or three or more.

  A cutter 36 for cutting the photosensitive recording paper 34 is provided at a position away from the outlets of the magazines 20a and 20b by a predetermined length. The cutter 36 is driven in response to a control signal from the control unit 17, and cuts the photosensitive recording paper 34 sent out by a predetermined length according to the print size to form the recording paper S. As the print size, for example, L (89 × 127) (unit: mm, the same applies hereinafter), panorama (89 × 254), 2L (127 × 178), 8 cuts (165 × 216), 6 cuts (203 × 254) ) 4 cuts (254 × 305). In this embodiment, if the print width in the direction orthogonal to the transport direction is 152 mm or less, the print is transported in two rows, and if it exceeds 152 mm, it is transported in one row.

  The back print unit 22 includes a back print head 38 that records print information such as a photograph date, print date, frame number, and various IDs on a non-recording surface (surface opposite to the exposure surface) of the recording paper S. . As the back print head 38, a known print head such as a dot impact head, an ink jet head, or a thermal transfer print head can be used.

  The registration unit 24 includes a registration roller pair 40 that adjusts the tilt and the width direction position of the recording paper S in order to prevent an exposure position / angle shift in the image recording unit 26, and a front and rear of the registration roller pair 40. It is comprised from the some conveyance roller pair arrange | positioned. As a method of adjusting the tilt and the width direction position by the resist roller pair 40, known methods such as a tilt resist, a top resist, and a side resist can be used.

  The image recording unit 26 includes an exposure unit 42, sub-scanning roller pairs 44 and 46, and a recording sheet sensor 45 that detects the passage of the recording sheet S, and the operation of the control unit 17 is controlled. The exposure unit 42 is connected to the image processing apparatus 13, and when the recording paper sensor 45 detects that the leading edge of the recording paper S has passed, the light beams of red, green, and blue that are intensity-modulated based on the image data. The LB is scanned in the main scanning direction (direction orthogonal to the transport direction), and an image is recorded on the recording paper S. The sub-scanning roller pairs 44 and 46 are arranged on the upstream side and the downstream side in the transport direction so as to sandwich the exposure position by the light beam LB, and the recording paper S is moved at a predetermined speed in the sub-scanning direction (parallel to the transport direction). Direction). The nip rollers of the sub-scanning roller pairs 44 and 46 can be switched between a position where the recording paper S is sandwiched and a position where the recording paper S is separated from the recording paper S, and the leading end of the recording paper S is detected by a position sensor (not shown). Or it is switched when the rear end is detected. As a result, the leading edge of the recording paper S abuts against the downstream sub-scanning roller pair 46 or the trailing edge slips out of the upstream sub-scanning roller pair 44, thereby causing an excessive impact on the recording paper S. To prevent.

  The sub-scan receiving unit 28 includes a plurality of roller pairs that hold the leading end portion of the recording paper S that is sent out from the image recording unit 26 during image recording, and performs recording at the same speed as the conveyance speed of the image recording unit 26. The paper S is sent out downstream. Each roller pair of the sub-scanning receiving unit 28 includes a driving roller and a nip roller capable of releasing the nip, and holds the recording paper S after the leading edge of the recording paper S during image recording passes. This prevents the conveyance speed from fluctuating due to the leading edge of the recording paper S hitting.

  The sorting unit 30 sorts the recording sheets S conveyed in a single row into two rows in the main scanning direction while conveying the recording paper S at a predetermined first speed. Further, the carry-out unit 32 conveys the recording paper S sent from the sorting unit 30 at a second speed corresponding to the processing speed of the processor 16 and sends it to the processor 16. The sorting unit 30 and the carry-out unit 32 are provided with a sensor unit 48 and a sensor unit 50 for detecting the presence or absence of the recording paper S, respectively. The sensor units 48 and 50 are optical sensors composed of, for example, a light emitting diode and a photodiode, and the output changes while the recording paper S passes. Thereby, the passage of the leading edge or the trailing edge of the recording paper S can be detected.

  The processor 16 includes a development processing unit 60, a drying processing unit 61, a returning unit 62, and a sorter 63. The development processing unit 60 includes a developing tank 70, a bleach-fixing tank 71, a first water washing tank 73, a second water washing tank 74, a third water washing tank 75, and a fourth water washing tank 76 in order from the upstream side in the transport direction. A water rinsing tank 72 is provided. The developing tank 70 contains a developer, the bleach-fixing tank 71 contains a bleach-fixing liquid (the developing solution and the bleach-fixing solution are collectively referred to as “processing solution”), and the first washing tank 73 to the fourth washing tank 76. Each has a predetermined amount of washing water stored therein. The recording sheet S is sequentially conveyed through the developing tank 70, the bleach-fixing tank 71, and the first washing tank 73 to the fourth washing tank 76, and each process of development, fixing, and washing is performed.

  The drying process part 61 is arrange | positioned above each process tank 70-72, and is comprised from the conveyance belt and the ventilation duct. The blower duct blows dry air heated by a heater toward the conveyance belt, and presses the recording paper S toward the conveyance belt. In this state, the cleaning water adhering to the recording paper S is removed by passing over the air duct.

  The recording sheet S that has passed through the drying processing unit 61 is sent toward the returning unit 62. In the returning unit 62, the recording paper S conveyed in two rows is returned in a single row. The sorter 63 collectively outputs a plurality of recording sheets S sent from the returning unit 62 for each print job.

  Next, the squeeze unit 80 provided between the development processing unit 60 and the drying processing unit 61 will be described.

  As shown in FIG. 2, the squeeze unit 80 includes, in order from the upstream side in the transport direction, along the arc-shaped transport path R extending from the development processing unit 60 disposed on the lower side to the drying processing unit 61. A first upstream roller pair 82, a second upstream roller pair 84, a first downstream roller pair 86, and a second downstream roller pair 88 are arranged. Each of these roller pairs includes two rotating rollers 82A and 82B, rotating rollers 84A and 84B, rotating rollers 86A and 86B, and rotating rollers 88A and 88B. The rotating shaft of each rotating roller is orthogonal to the conveying direction. It is arranged along the direction. Each of the first upstream roller pair 82, the second upstream roller pair 84, and the first downstream roller pair 86 holds the recording paper S between the two rotating rollers, and moves the recording paper S downstream. Rotate in the transport direction. The second downstream roller pair 88 rotates in a direction in which the recording paper S is conveyed downstream while the recording paper S is in contact with the roller 88B on one side.

  The first upstream cleaning means 92 is located at a position away from the upper conveyance path R of the first upstream roller pair 82, and the second upstream position is located at a position away from the upper conveyance path R of the second upstream roller pair 84. The first downstream cleaning means 96 is disengaged from the upper conveying path R of the second downstream roller pair 88 at a position where the side cleaning means 94 is deviated from the upper conveying path R of the first downstream roller pair 86. The second downstream side cleaning means 98 are respectively arranged at the positions. The first upstream side cleaning means 92, the second upstream side cleaning means 94, the first downstream side cleaning means 96, and the second downstream side cleaning means 98 are fixed to the casing 80A of the squeeze portion 80 and connected to the pipe 91. The cleaning water from a cleaning water tank (not shown) is supplied via the pump P (see FIG. 3). Since each cleaning means is fixed to the casing 80A fixed to the processor 16 of the squeeze portion 80, each cleaning means remains on the processor 16 side even if the roller pair is removed during maintenance and inspection. A complicated configuration is unnecessary.

  As shown in FIG. 3, the first upstream side cleaning means 92 includes a pipe 92A in which an injection port 92B is formed. The injection port 92B is formed in six places, two at the center of the pipe 92A and two at each side. The positional relationship between each ejection port 92B and the recording paper S conveyed is when the recording paper S is conveyed in two rows. For example, when the recording paper S is 127 mm wide, as shown in FIG. One ejection port 92B is disposed on the outer side of the recording sheet, and the second ejection port 92B from the outermost side is disposed on the inner side of the end of the recording paper S. Further, in the case where the recording paper S is conveyed in one row, for example, with a width of 254 mm, two ejection ports 92B are arranged outside both ends of the recording paper S as shown in FIG. Two injection ports 92B are arranged in the section. The ejection ports 92B are densely arranged in the vicinity of the end of the recording paper S regardless of whether the conveyance pattern is one row or two rows. Wash water is jetted from each jet 92B to the first upstream roller pair 82. The sprayed cleaning water is directly applied to the nip portion of the first upstream roller pair 82.

  Similar to the first upstream side cleaning unit 92, the second upstream side cleaning unit 94 is also configured by a pipe 94A in which an injection port 94B is formed. The number and the formation positions of the ejection ports 94B, the positional relationship with the recording paper S, and the ejection position of the cleaning water are the same as those of the first upstream cleaning unit 92.

  As shown in FIG. 3, the first downstream side cleaning means 96 includes a pipe 96 </ b> A in which an injection port 96 </ b> B is formed. The injection ports 96B are formed at a total of 11 locations, 5 at the center of the pipe 92A and 3 at each side. The positional relationship between each ejection port 96B and the recording paper S being conveyed is when the recording paper S is conveyed in two rows. For example, when the recording paper S is 127 mm wide, as shown in FIG. Three ejection ports 96B are arranged, one ejection port 96B is arranged outside the outer edge of each row of recording paper S, and three ejection ports 96B are arranged inside each row of recording paper S. Is placed. Further, in the case where the recording paper S is conveyed in one row, for example, for a width of 254 mm, two ejection ports 96B are arranged outside both ends of the recording paper S as shown in FIG. Seven injection ports 96B are arranged in the center. The jet ports 96B are densely arranged in the vicinity of the end of the recording paper S regardless of whether the conveyance pattern is one row or two rows. A guide member 87 is disposed above the roller pair 86, and cleaning water is jetted from each jet port 96 </ b> B toward the guide member 87. The sprayed cleaning water is once applied to the guide member 87, diffused in the axial direction, and supplied to the first downstream roller pair 96.

  Similarly to the first downstream side cleaning unit 96, the second downstream side cleaning unit 98 is also configured by a pipe 98A in which an injection port 98B is formed. The number of the ejection ports 98 </ b> B, the formation position, and the positional relationship with the recording paper S are the same as those of the first downstream cleaning unit 96. A guide member 89 is disposed on the upper part of the roller pair 88, and cleaning water is jetted toward the guide member 89 from each jet port 98B. The sprayed cleaning water is once applied to the guide member 89, diffused in the axial direction, and supplied to the second downstream roller pair 98.

  Water removal of the recording paper S in the squeeze unit 80 having the above-described configuration is performed according to the following procedure. First, the first upstream roller pair 82 rotates while nipping the recording paper S, and transports the recording paper S to the second upstream roller pair 84 side while squeezing out moisture adhering to the surface of the recording paper S. The recording sheet S is sequentially nipped between the second upstream roller pair 84 and the first downstream roller pair 86 and conveyed downstream while moisture is squeezed out. The second downstream roller pair 88 removes droplets remaining on the trailing edge of the recording paper S by bringing the recording paper S into contact with the roller 88B on one side without sandwiching the recording paper S. The recording sheet S that has passed through the second downstream roller pair 88 is conveyed to the drying unit 61 and subjected to a drying process.

  As described above, each roller pair that removes moisture from the recording paper S by contact is contaminated by the treatment liquid component or the like due to contact with the recording paper S. This dirt tends to concentrate on the outer end portion including the vicinity of the end of the contact area. Further, since the roller pair on the downstream side is dryer than the upstream side, dirt is concentrated. Therefore, at a predetermined timing, cleaning water is sprayed from the spray ports of the respective cleaning means to clean each roller pair.

  In the present embodiment, since the injection ports are densely formed in the portion corresponding to the portion where the dirt in the axial direction of each roller pair is concentrated, the portion where the dirt is concentrated can be cleaned intensively. Further, the number of injection ports formed in the first downstream side cleaning unit 96 and the second downstream side cleaning unit 98 is larger than the number of injection ports formed in the first upstream side cleaning unit 92 and the second upstream side cleaning unit 94. It is possible to clean the roller pair on the downstream side where the concentration is increased more carefully and to clean the roller pair more efficiently.

  In this embodiment, the roller pair on the downstream side is more carefully cleaned by increasing the number of injection ports, but by increasing the diameter of the injection ports or increasing the injection pressure of the cleaning liquid to be injected, It can also be washed carefully.

  Further, in this embodiment, the cleaning water from the downstream cleaning means is once applied to the guide member and then diffused in the axial direction of the roller pair and supplied to the roller pair. Can be washed.

  Note that a relatively large amount of moisture is attached to the recording paper S passing through the first upstream roller pair 82 and the second upstream roller pair 84, and the first upstream roller pair 82 and the second upstream roller. The adhesion of dirt to the pair 84 is rarely concentrated near the end of the recording paper S. Therefore, the injection ports of the first upstream side cleaning unit 92 and the second upstream side cleaning unit 94 are formed at equal intervals as shown in FIG. 6, and the first upstream roller pair 82 and the second upstream roller pair 84 are formed. May be cleaned uniformly.
