Description

[Technical field]

[0001] The present invention relates to a lamination device, an image forming device, and an image forming system. [Background technology]

[0002] A technology known as lamination involves inserting an inner layer (paper, photographs, etc.) between two sheets that have been stacked and joined (connected) at one side (laminating sheet or laminating film), and then applying heat and pressure to bond the two sheets together.

[0003] In conventional laminating machines, the inner sheets (paper, photos, etc.) to be sandwiched between the film must be sandwiched one by one by hand, but because the film has an adhesive layer on the inside, it is difficult to peel off by hand, and after peeling, it is also troublesome to sandwich the sheets to be sandwiched in the correct position. In addition, when one sheet is prepared and set in the processing machine (laminator), it takes 30 to 60 seconds to laminate, so it is necessary to wait until the next processing. As a result, even if only a few dozen sheets are laminated, the person cannot leave the laminating processing device for a long time, and the user must repeat the work of sandwiching the sheets, setting it, laminating, sandwiching the sheets while waiting, etc., which requires time and manpower. In addition, if you try to avoid this, you need a dedicated laminating device that uses roll film, which is very expensive (hundreds of thousands to millions of yen).

[0004] To solve this problem, a technology is known in which a space is formed in the sheet where one side of the sheet is connected by wrapping the sheet around a winding roller, and a peeling claw is inserted into the space to peel the front and back sides of the sheet off (Patent Document 1).

[0005] However, because the sheets are bonded by applying heat and pressure with the hot and pressure roller, excess glue from the sheets and dust caught in the sheets may adhere to the hot and pressure roller, and in some cases the sheet may get caught in the hot and pressure roller, causing the device to break down.

[0006] To avoid this, it was necessary to periodically pass a sheet called a cleaning sheet through the roller to remove dirt from the roller. However, because the size of the cleaning sheet (A4 size) was smaller than the size of the sheet (laminate film), it was necessary to either handcraft a cleaning sheet that could clean the roller over an area equal to or larger than the width of the sheet, or to pass the A4 size cleaning sheet through the roller multiple times to clean the roller, which required time and effort for cleaning. Summary of the Invention [Problem to be solved by the invention]

[0007] Therefore, an object of the present invention is to reduce the time and labor required for cleaning the fixing unit in a lamination processing device in which a sheet-like medium is sandwiched between two overlapping sheets. [Means for solving the problem]

[0008] This problem is solved by a lamination processing device that sandwiches a sheet-like medium between two sheets that are overlapped and partially joined together, the lamination processing device comprising a first stacking means for stacking the sheet-like medium or the cleaning sheet. And , a first stacking means having a moving means for moving the sheet-like medium or the cleaning sheet in a direction perpendicular to a conveying direction; The lamination unit has a fixing unit for laminating the two-ply sheet with the sheet-like medium sandwiched therebetween, and the fixing unit is cleaned. Therefore, multiple cleaning sheets are fed. In cleaning mode The cleaning sheets set on the first stacking means by the user are automatically moved to different positions perpendicular to the conveying direction by the moving means, and then The aforementioned problem is solved by a lamination processing apparatus characterized in that the subsequent cleaning sheet is conveyed at a position different from the position perpendicular to the conveying direction of the preceding cleaning sheet. Effect of the Invention

[0009] In a lamination processing device in which a sheet-like medium is sandwiched between two overlapping sheets, the time and effort required for cleaning the fixing unit can be reduced. [Brief description of the drawings]

FIG. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] 1 is an overall configuration diagram of a sheet processing apparatus according to an embodiment of the present invention. The sheet processing apparatus 100 of this embodiment separates two stacked sheets (hereinafter referred to as sheets S) from each other, and inserts and holds a sheet-like medium (hereinafter referred to as an inner sheet P) between the separated sheets S.

[0012] Here, the sheet S is a two-ply sheet in which two sheets are stacked and a part (or one side) of the two sheets are joined together. For example, a two-ply sheet may be one in which one side is a transparent sheet such as a transparent polyester sheet and the other side is a transparent or opaque sheet, and the two sheets are joined together at one side. A laminate film is also included as a two-ply sheet.

[0013] The inner page P is an example of a sheet-like medium that is inserted between these two stacked sheets. In addition to plain paper, sheet-like media includes cardboard, postcards, envelopes, thin paper, coated paper (coated paper, art paper, etc.), tracing paper, and OHP sheets.

[0014] 1, the sheet processing apparatus 100 includes a paper feed tray 102 serving as a first stacking means for stacking the inner pages P, a pickup roller 105 for feeding the inner pages P from the paper feed tray 102, a pair of conveying rollers 107, and a path for reversing the inner pages P. The sheet processing apparatus 100 also includes a paper feed tray 103 serving as a second stacking means for stacking the sheets S, and a pickup roller 106 for feeding the sheets S from the paper feed tray 103.

[0015] The sheet processing apparatus 100 has different paper feed paths and transport paths, and in order to improve productivity, the straight path is used to transport the sheet S to be peeled off, thereby transporting the sheet S in the shortest distance. Since the inner sheet P needs to wait until the sheet peeling operation is completed, it is separated and fed in advance, and is made to wait on a reversible transport path with a sufficient distance to wait.

[0016] In order to achieve both compactness and improved productivity, the path from pickup roller 106, which conveys sheets, to the pair of inlet rollers 108 is configured to be shorter than the path from pickup roller 105, which conveys the inner paper, to the pair of inlet rollers 108, and these paths join upstream of the pair of inlet rollers 108.

[0017] After the insertion of the inner page P is completed, the sheet S is discharged and stacked on the discharge tray 104 by the pair of exit rollers 113 or rollers arranged thereafter. By providing a path for reversing the inner page P, it is possible to discharge and stack the inner page P on the discharge tray 104 in the page order stacked on the paper feed tray 102.

[0018] A transport sensor C1 for detecting the transport position of the inner sheet P is provided downstream of the transport roller pair 107 in the transport direction, and a transport sensor C2 for detecting the transport position of the sheet S is provided downstream of the pickup roller 106 in the transport direction.

[0019] The sheet processing apparatus 100 further includes, downstream of the conveying roller pair 107 and the pickup roller 106, an entrance roller pair 108 as a first conveying means, a winding roller 109 as a rotating member, an exit roller pair 113 as a second conveying means, and a paper discharge tray 104. A peeling claw 116 is provided between the winding roller 109 and the exit roller pair 113 so as to be movable in the width direction of the sheet S. The peeling claw 116 is an example of a peeling means that peels off the sheet S.

[0020] A transport sensor C3 that detects the transport positions of the sheet S and the inner paper P is provided downstream of the entrance roller pair 108 in the transport direction, and an abnormality detection sensor C4 that detects the state of the sheet S is provided downstream of the winding roller 109 in the transport direction. And a transport sensor C5 that detects the transport position of the sheet S is provided downstream of the exit roller pair 113 in the transport direction.

[0021] The pickup roller 105, the pair of conveying rollers 107, the pair of entrance rollers 108, and the winding roller 109 are an example of a first feeding means, and the pickup roller 106, the pair of entrance rollers 108, and the winding roller 109 are an example of a second feeding means.

[0022] An operation panel 10, which is a display operation means for displaying information on the sheet processing apparatus 100 and receiving operation inputs, is provided on the exterior of the sheet processing apparatus 100. The operation panel 10 also serves as a notification means for issuing a sensory signal to the user. Alternatively, a notification means other than the operation panel 10 may be provided separately in the sheet processing apparatus 100.

[0023] The sheet processing apparatus 100 of this embodiment stacks the sheets S and the inner pages P on separate trays, and while transporting the sheets S, separates and opens the two sheets, and inserts the inner pages P into the opening. Then, the sheets S with the inner pages P inserted therein are discharged and stacked on the discharge tray 104.

[0024] Fig. 2 is a configuration diagram (part 1) showing the main parts of the sheet processing apparatus shown in Fig. 1. As shown in Fig. 2, the entrance roller pair 108 and the exit roller pair 113 are, for example, two rollers in pairs, each of which is rotationally driven by a driving means (such as a motor). The entrance roller pair 108 is rotationally driven in one direction, and the exit roller pair 113 is rotationally driven in forward and reverse directions, thereby sandwiching and transporting the sheet S and the inner page P.

[0025] The entrance roller pair 108 transports the sheet S and the inner page P toward the exit roller pair 113. This transport direction is called the forward transport direction (the direction of the arrow A).

[0026] Meanwhile, the pair of exit rollers 113 can switch their rotation between forward and reverse directions. The sandwiched sheet S can be transported toward the discharge tray 104 (see FIG. 1) in the forward transport direction, and can also be transported toward the winding roller 109 in the reverse direction (pull-back direction). This direction of transport toward the winding roller 109 (the opposite direction to the forward transport direction) is called the reverse transport direction (the direction of arrow B).

[0027] The sheet processing apparatus 100 also includes a winding roller 109 and a peeling claw 116, which are rotating members, between the pair of entrance rollers 108 and the pair of exit rollers 113. The winding roller 109 is driven to rotate in forward and reverse directions by a driving means (such as a motor), and its rotation can be switched between two directions (clockwise / counterclockwise).

[0028] The winding roller 109 has a roller member 111 and a movable gripping means 110 that is provided on the roller member 111 and grips the sheet S. The movable gripping means 110 is characterized by gripping the leading edge of the sheet S together with the roller member 111. The gripping means 110 may be integrally formed on the outer periphery of the roller member 111, or may be configured as a separate part.

[0029] 1 to 14, a series of operations of the sheet processing device 100, that is, operations from peeling off the sheet S to inserting the inner sheet P, will be described. In addition, in Figs. 3 to 14, the same components as those in Figs. 1 and 2 are given the same reference numerals and detailed descriptions thereof will be omitted.

[0030] 1, the sheets S on the paper feed tray 103 are stacked so that a portion of the joined two sheets is located downstream in the feed direction (conveyance direction) of the pickup roller 106. Then, the sheet processing apparatus 100 picks up the sheet S on the paper feed tray 103 with the pickup roller 106 and conveys it toward the inlet roller pair 108.

[0031] 2, the sheet S is conveyed by the inlet roller pair 108 toward the winding roller 109. Here, the sheet processing apparatus 100 conveys the sheet S with the side where one of the four sides of the sheet S, that is, an end portion, joined, being the downstream side in the forward conveying direction (the direction of the arrow A).

[0032] 3, the sheet processing apparatus 100 temporarily stops conveying the sheet S when the rear end of the sheet S in the forward conveying direction passes the winding roller 109. Note that these operations are triggered by detection of the leading end of the sheet S by the conveying sensor C3, and are performed by conveying the sheet S by a specified amount from the conveying sensor C3.

[0033] Next, as shown in FIG. 4, the sheet processing apparatus 100 opens the gripping means 110, reverses the rotation direction of the pair of outlet rollers 113, and conveys the sheet S toward the opening of the gripping means 110 in the reverse conveying direction (the direction of the arrow B).

[0034] 5, the sheet processing apparatus 100 stops conveying the sheet S when the edge of the sheet S is inserted into the open gripping means 110, and closes the gripping means 110 to grip the edge of the sheet S. These operations are performed by conveying the sheet S by a specified amount.

[0035] 6, the sheet processing apparatus 100 rotates the winding roller 109 counterclockwise to wind the sheet S around the winding roller 109. Here, the sheet S is wound around the winding roller 109 from the side of the two sheets that is not joined together.

[0036] As shown in Fig. 7, when the sheet S is wound around the winding roller 109, the difference in winding circumferential length (difference in winding amount) of the two overlapping sheets causes excess sheet on the inner circumference side, and slack occurs toward the joined end of the sheet S. As a result, a space is created between the two sheets. By inserting the peeling claws 116 into this created space from both sides of the sheet S, it is possible to reliably maintain the space between the two sheets. Note that these operations are triggered by detection of the leading edge of the sheet S by the transport sensor C5, and are performed by transporting the sheet S by a specified amount from the transport sensor C5.

[0037] The sheet processing apparatus 100 rotates the winding roller 109 clockwise with the peeling claw 116 inserted into the space created in the sheet S (see FIG. 7), and moves the peeled space of the sheet S to the rear end of the sheet S in the forward conveying direction (the direction of the arrow A) as shown in FIG. 8. Then, when the designated amount of movement has been reached, the gripping means 110 is released, and the rear end of the sheet S is separated into upper and lower parts.

[0038] In this state, the sheet processing apparatus 100 temporarily stops conveying the sheet S, and then moves the peeling claw 116 further in the sheet width direction to peel off the entire rear end of the sheet S. Note that these operations are triggered by detection of the leading edge of the sheet S by the conveying sensor C5, and are performed by conveying the sheet S by a specified amount from the conveying sensor C5.

[0039] 8, the sheet processing apparatus 100 then rotates the pair of exit rollers 113 counterclockwise to transport the sheet S in the reverse transport direction (the direction of the arrow B) as shown in FIG. 9. When the leading edge of the sheet passes the transport sensor C5, the branch claw 118 can be switched. When the sheet S is transported to the non-fixing path, the branch claw 118 remains in the position shown in the figure, but when the sheet S is transported to the fixing path 128, the branch claw 118 is switched to the fixing path side.

[0040] The switching of the branch claw 118 should be completed between the timing when the leading edge of the sheet passes the conveyance sensor C5 and the timing when the leading edge of the sheet reaches the branch claw 118 after the insertion of the inner paper. If the branch claw 118 is switched before this timing, the sheet S before the insertion of the inner paper will enter the fixing path and part of the sheet will be fixed. Also, if the fixing unit is positioned further downstream to prevent this, the device will become larger.

[0041] 9, the two peeled sheets of the sheet S are guided vertically by the peeling claws 116, and the two sheets are peeled off from each other. Then, the sheet processing apparatus 100 temporarily stops the conveyance of the sheet S, and the joint portion of the sheet S is gripped (nipped) by the pair of outlet rollers 113. Therefore, the sheet S is opened widely with the jointed side as an end.

[0042] These operations are triggered by detection of the leading edge of the sheet S by the conveyance sensor C5, and are performed by conveying the sheet S by a designated amount from the conveyance sensor C5.

[0043] 10 to 12 show the operation of the sheet processing apparatus 100 when the sheet S is transported to the fixing path 128 in the case where the user selects the lamination processing mode on the operation panel 10. FIG. Next, as shown in FIG. 10, the sheet processing device 100 rotates the entrance roller pair 108 and transports the inner sheet P transported from the paper feed tray 102 (see FIG. 1) by the pickup roller 105 and the transport roller pair 107 in the forward transport direction (arrow A direction) toward the exit roller pair 113.

[0044] 11, the sheet processing apparatus 100 rotates the pair of outlet rollers 113 to merge the sheet S and the inner page P, and inserts the inner page P into the sheet S that has been opened.

[0045] 12, the sheet processing apparatus 100 transports the sheet S with the inner paper P inserted in the forward transport direction (the direction of the arrow A) by the pair of exit rollers 113, thereby overlapping the two sheets of the sheet S again and closing the opening. Then, the sheet S with the inner paper P sandwiched therebetween is transported to a fixing section having a heat and pressure roller 120 by the pair of exit rollers 113 or rollers arranged thereafter, and is discharged and stacked on the discharge tray 104 (see FIG. 1). 2 to 12 show the basic peeling operation and the transport operation to the fixing Md (fixing unit) in the case of lamination processing.

[0046] In this way, the sheet processing device 100 of this embodiment can open the sheet S widely and insert and clamp the inner paper P therein. Therefore, compared to the laminating device of Patent Document 2 that uses a vacuum device, for example, the configuration is simpler, and the entire device can be simplified and made smaller.

[0047] 1, the sheet processing apparatus 100 of the present embodiment can stack the sheets S and the inner pages P on separate trays and transport them separately. This eliminates the need to stack the sheets S and the inner pages P in a predetermined order, improving convenience.

[0048] On the other hand, when the user selects the inner sheet insertion mode on the operation panel 10, the sheet processing apparatus 100 operates as shown in FIGS. 2 to 9, the sheet processing apparatus 100 operates in the same manner, but as shown in FIG. 13, in order to transport the inner sheet P to the non-fixing path 129, the branch claw 118 is not switched and the inner sheet P is transported as is.

[0049] 14, while both the sheet S and the inner page P are held (nipped), the sheet S and the inner page P are transported by an exit roller pair 113, thereby inserting the inner page P between the two sheets S. The sheet S is then transported to a non-fixing path 129 that does not have a heat and pressure roller 120, and is discharged and stacked on a paper discharge tray 126 (see FIG. 15), completing the paper discharge. In this way, the user can obtain the sheet with the inner page inserted, and the sheet can be subjected to fixing processing in an offline machine.

[0050] In the above-mentioned sheet processing apparatus 100 or the lamination processing apparatus 200 described later, a user can select a cleaning mode using the operation panel 10 to transport multiple cleaning sheets. In this case, the subsequent cleaning sheet can be transported to a position different from the position perpendicular to the transport direction of the preceding cleaning sheet. This will be described below using a lamination processing device 200.

[0051] FIG. 15 is a general configuration diagram showing an example of a lamination processing device equipped with a sheet processing device according to the present invention. The lamination processing device 200 includes the sheet processing device 100 described above. The lamination processing device 200 has a peeling claw 116 which is a peeling means for peeling the sheet S, an exit roller pair 113 which is a conveying means for conveying the sheet S and is disposed downstream of the peeling claw 116, and a branching claw 118 which is a switching means for switching the conveying path of the sheet S and is disposed downstream of the exit roller pair 113. The branching claw 118 conveys the sheet S to a fixing path 128 for fixing the sheet S or a non-fixing path 129 (see FIG. 12 and FIG. 14) which does not fix the sheet S. This makes it possible for the user to select the non-fixing mode (inner sheet insertion mode) and discharge the sheet S using the non-fixing path 129 without fixing it with the inner sheet P inserted into the sheet S. Therefore, inserting the inner pages is automated and hassle-free, and the user can perform lamination work on a separate offline machine, enabling parallel work, thereby improving work productivity.

[0052] The lamination processing device 200 also includes an output roller 121 disposed downstream of the heat and pressure roller 120, an output tray 104 for stacking sheets S transported through a fixing path 128, and an output tray 126 for stacking sheets S transported through a non-fixing path 129 that does not have a heat and pressure roller 120.

[0053] This lamination processing device 200 is configured to perform a series of operations from feeding the sheets S, peeling them, inserting the inner sheets P, and laminating them by heat and pressure, all in one machine. This series of operations can be performed automatically without the need for human labor, making it more convenient than conventional techniques.

[0054] However, lamination processing is only one example of sheet processing, and lamination processing devices may be broadly called sheet processing devices.

[0055] As in the above-described sheet processing device 100, in the lamination processing device 200, the sheet S after the insertion of the inner page is discharged and stacked on the paper output tray 104 by the exit roller pair 113 or a roller arranged thereafter. By providing a path for reversing the inner page P, it is possible to discharge and stack the sheets on the paper output tray 104 in the page order stacked on the paper feed tray 102.

[0056] FIG. 16 is a schematic perspective view of the paper feed tray 102 for loading the inner sheets P or cleaning sheets. At the rear side of the paper feed tray 102 of the lamination processing device 200, paper edge detection sensors C6 and C7 for detecting the paper edge are arranged, and the edge of the cleaning sheet loaded on the paper feed tray 102 is detected by the paper edge detection sensors C6 and C7. In this specification, unless otherwise specified, "edge" refers to "main scanning direction edge" (left and right direction in the figure). In addition, the paper feed tray 102 is provided with side fences or joggers 151 and 152 that can move in the main scanning direction and regulate the main scanning direction edge of the paper. The side fences or joggers 151 and 152 are an example of a moving means for moving the inner paper P or the cleaning sheet in a direction perpendicular to the conveying direction. Since the inner paper P has the same size as the cleaning sheet, the description of the inner paper P also applies to the cleaning sheet, and vice versa. As the detection sensor, an optical sensor such as a reflective sensor or a transmission sensor using a filler may be used. Alternatively, an imaging element such as the paper edge detection sensor C10 may be used.

[0057] 17 to 20 are schematic diagrams showing the movement of the cleaning sheet in the main scanning direction. First, an embodiment will be described for moving a position (main scanning direction position) perpendicular to the transport direction of the cleaning sheet before transporting (feeding) the cleaning sheet using the paper feed tray 102. Hereinafter, this movement will be referred to as "pre-transport position movement" where appropriate. In FIG. 17, the paper edge detection sensors C6 and C7 as the detection means are arranged to match the end positions of the heat and pressure roller 120 and the sheet S, which are larger than A4 size (short side of A4), such as the inner sheet P, perpendicular to the conveying direction. Therefore, the paper edge detection sensors C6 and C7 cannot detect both ends of the cleaning sheet of A4 size (short side of A4). Therefore, if both ends of the inner sheet P are not detected, the lamination processing device 200 moves the side fences or joggers 151 and 152 in the main scanning direction. In this example, in order to detect the inner sheet P with the paper edge detection sensor C6, the side fence or jogger 152 is moved leftward in the figure, and the inner sheet P is moved from the original broken line position to the solid line position. The movement of the side fence or jogger 151 in the main scanning direction can be performed automatically or manually by the user.

[0058] 18, after the side fence 152 of the paper feed tray 102 of the lamination processing device 200 is moved leftward, when the edge of the cleaning sheet is detected by the paper edge detection sensor C6, the pickup roller 105 starts feeding the cleaning sheet from the paper feed tray 102. The cleaning sheet is fed and transported in the sub-scanning direction perpendicular to the main scanning direction, as shown by the arrow in the figure.

[0059] 19, in order to transport the succeeding cleaning sheet at a position different from the position perpendicular to the transport direction of the preceding cleaning sheet, the side fence or jogger 151 is moved to the right in the figure until the edge of the cleaning sheet is detected by the paper edge detection sensor C7. In order to detect the inner sheet P with the paper edge detection sensor C7, the inner sheet P is moved from its original broken line position to the solid line position. The movement of the side fence or jogger 151 in the main scanning direction is performed automatically or manually by the user.

[0060] In FIG. 20, after the side fence 151 of the paper feed tray 102 of the lamination processing device 200 is moved rightward, when the edge of the cleaning sheet is detected by the paper edge detection sensor C7, the pickup roller 105 starts feeding the cleaning sheet from the paper feed tray 102.

[0061] In this manner, a plurality of cleaning sheets set in the paper feed tray 102 by the user are automatically or manually moved by the side fences or joggers 151 to different positions perpendicular to the conveying direction.

[0062] As described above, according to the lamination processing device 200 of this embodiment, in the cleaning mode for cleaning the hot pressure roller 120, a plurality of cleaning sheets, which are cleaning means for cleaning the hot pressure roller 120, are conveyed, and the succeeding cleaning sheet is conveyed at a position different from the position perpendicular to the conveying direction of the preceding cleaning sheet. This eliminates the need to repeatedly pass the cleaning sheet through the hot pressure roller 120 over an area equal to or larger than the width of the sheet S, which occurs because the cleaning sheet (A4 size) is smaller than the size of the sheet S, and reduces the labor and time required for this.

[0063] Furthermore, according to the lamination processing device 200 of this embodiment, the succeeding cleaning sheet is moved to a position in the paper feed tray 102 that is different from the position perpendicular to the conveying direction of the preceding cleaning sheet before the succeeding cleaning sheet is conveyed. This eliminates the time and manpower required to set up the succeeding cleaning sheet, which had to be moved to a position different from that of the preceding cleaning sheet in order to clean the heat and pressure roller 120 over an area equal to or greater than the width of the sheet S.

[0064] In addition, before the subsequent cleaning sheet is conveyed, the user moves the subsequent cleaning sheet to a position different from the position perpendicular to the conveying direction of the preceding cleaning sheet. By moving the cleaning sheet before conveyance, the user can clean an area of ​​the heat and pressure roller 120 that is equal to or larger than the sheet width.

[0065] Furthermore, multiple cleaning sheets set in the paper feed tray 102 by the user are automatically moved to different positions perpendicular to the conveying direction by the side fences or joggers 151, 152. During conveying, the preceding cleaning sheet and the succeeding cleaning sheet are conveyed over an area equal to or greater than the sheet width of the heat and pressure roller 120. This allows the user to automatically clean the heat and pressure roller 120 over an area equal to or greater than the sheet width simply by setting the cleaning sheets.

[0066] Also, the cleaning sheet may be fed without performing the peeling operation of the sheet S. By feeding only the cleaning sheet, the cleaning time can be shortened.

[0067] Furthermore, in the lamination processing device 200 of this embodiment, the paper feed tray 102 can hold sheets S, and the paper edge detection sensors C6, C7 as detection means can detect whether the sheets S and the inner pages P or the cleaning sheets are loaded on the paper feed tray 102. This makes it possible to distinguish between the sheets S and the inner pages (cleaning sheets), and therefore determines the timing for feeding and transporting the sheets S and the inner pages (cleaning sheets).

[0068] Furthermore, the lamination processing device 200 in this embodiment has a transport sensor C1 as another detection means for detecting the leading and trailing ends of the sheet S, the inner paper P, or the cleaning sheet, downstream in the transport direction of the paper feed tray 102 (FIG. 15). This makes it possible to determine the state detection and transport timing of the sheet S and the inner paper, and also allows the user to set the cleaning sheet without worrying about the length in the sub-scanning direction.

[0069] Next, an embodiment will be described in which the position of the cleaning sheet in the main scanning direction is moved by moving the pair of exit rollers 113 in the main scanning direction after the cleaning sheet has been fed.

[0070] FIG. 21 is a diagram showing the overall configuration of an example of a lamination processing apparatus equipped with a sheet processing apparatus according to the present invention. In this embodiment, first, paper feeding is started from the paper feed tray 102, and after the cleaning sheet passes through the transport path, the pair of exit rollers 113 corrects the inclination of the cleaning sheet. Specifically, the skew correction of the cleaning sheet is performed by abutting the leading edge of the cleaning sheet against the pair of exit rollers 113, so that the leading edge of the cleaning sheet is aligned with the nip line of the pair of exit rollers 113. If the pre-conveyance position movement described above has been performed, this skew correction operation is not necessarily required.

[0071] FIG. 22 is a schematic diagram showing the movement of the outlet roller pair 113 in the main scanning direction. After the inclination of the cleaning sheet is corrected in the lamination processing device 200, the conveyance of the cleaning sheet is resumed. Then, the sheet edge detection sensor C10 detects the sheet edge to detect the amount of correction in the main scanning direction of the sheet, and the exit roller pair 113 is moved in the main scanning direction to move the main scanning direction position of the cleaning sheet.

[0072] In Fig. 22(a), the cleaning sheet is shifted from its original broken line position to its solid line position by moving the exit roller pair 113 upward in the figure, and the upper end position shown by this solid line is, for example, a position passing through one end of the heat and pressure roller 120. In Fig. 22(b), the cleaning sheet is shifted from its original broken line position to its solid line position by moving the exit roller pair 113 downward in the figure, and the lower end position shown by this solid line is, for example, a position passing through the other end of the heat and pressure roller 120. When the cleaning sheet is moved in the main scanning direction, the entrance roller pair 108 is separated from the cleaning sheet so as not to interfere with the movement.

[0073] The above operation is repeated so that the succeeding cleaning sheet is conveyed to a position different from the position perpendicular to the conveying direction of the preceding cleaning sheet. Note that image detection by an imaging element is used to detect the edge of the paper by the paper edge detection sensor C10. However, an optical sensor that can grasp the distance to the sheet, such as an ultrasonic sensor or a distance measuring sensor, may also be used as the paper edge detection sensor C10.

[0074] FIG. 23 is a schematic diagram showing the positional relationship between the heat and pressure roller 120 and the cleaning sheet. In the lamination processing device 200, the sheet S is bonded by applying heat and pressure with the hot pressure roller 120, so that glue protruding from the sheet S and dust caught together with the sheet S will adhere to the hot pressure roller 120. However, as described above, it is possible to remove dirt by conveying the cleaning sheet to the hot pressure roller 120 in a range equal to or larger than the width of the sheet S (laminate film). In FIG. 23(a), the cleaning sheet is conveyed through the upper end of the hot pressure roller 120 in the figure, and the position of this cleaning sheet corresponds to the solid line position in FIG. 22(a). In FIG. 23(b), the cleaning sheet is conveyed through the lower end of the hot pressure roller 120 in the figure, and the position of this cleaning sheet corresponds to the solid line position in FIG. 22(b). Therefore, it is possible to prevent the sheet S from being caught due to dirt on the hot pressure roller 120, causing the device to break down.

[0075] According to the lamination processing device 200 of this embodiment, the succeeding cleaning sheet is moved to a position in the conveying path that is different from the position perpendicular to the conveying direction of the preceding cleaning sheet after being fed. This eliminates the time and manpower required to set up the succeeding cleaning sheet, which had to be moved to a position different from that of the preceding cleaning sheet in order to clean the heat and pressure roller 120 over an area equal to or larger than the width of the sheet S.

[0076] FIG. 24 is a diagram showing an overall configuration of an example of a lamination processing apparatus including a sheet processing apparatus according to an embodiment of the present invention. The lamination processing device 200 of this embodiment includes a paper feed tray 102 as a first stacking means for stacking the inner sheets P or sheets S, a pickup roller 105 for feeding the inner sheets P or sheets S from the paper feed tray 102, a pair of transport rollers 107, and a path for reversing the inner sheets P or sheets S. The lamination processing device 200 also includes a paper feed tray 103 as a second stacking means for stacking the inner sheets P or sheets S below the paper feed tray 102, a pickup roller 154 for feeding the inner sheets P or sheets S from the paper feed tray 103, a pair of transport rollers 155, and a path for reversing the inner sheets P or sheets S. These paths join upstream of an entrance roller pair 108.

[0077] At the rear side of the paper feed tray 102 of the lamination processing device 200, paper edge detection sensors C6 and C7 for detecting the paper edge are arranged, and at the rear side of the paper feed tray 103, paper edge detection sensors C8 and C9 for detecting the paper edge are arranged. FIG. 24 shows a state in which an inner sheet P fed from a paper feed tray 103 is conveyed and sandwiched between the sheets S fed from a paper feed tray 102.

[0078] FIG. 25 is a schematic overall view of the paper feed trays 102 and 103 on which the inner pages P or sheets S are loaded. In the lamination processing device 200, the inner paper P must wait until the sheet peeling operation is completed, so it is separated and fed in advance and made to wait on a reversible transport path with a distance for waiting. The main scanning direction ends of the inner paper P, cleaning sheet, or sheet S are detected by the paper end detection sensors C6, C7, C8, and C9. As the transport target, the sheet S is the transported object having the maximum width detected by the paper end detection sensors C6, C7, C8, and C9, so if the end is not detected by these detection sensors, it can be determined that the transported object is an inner paper P or a cleaning sheet other than the sheet S. To detect the end, an optical sensor such as a reflective sensor or a transmission sensor using a filler can be used. Alternatively, image detection by an imaging element is also possible.

[0079] By using such a configuration, the user can set the sheets S and the inner pages P in any paper feed tray without distinguishing between the multiple paper feed trays, and the sheets S after the inner pages have been inserted can be discharged and stacked in the output tray 104 by the exit roller pair 113 or rollers arranged thereafter in the page order stacked in the paper feed trays 102, 103.

[0080] FIG. 26 is a schematic diagram of an image forming apparatus according to an embodiment of the present invention. The image forming apparatus 300 has a sheet processing apparatus 100 or a lamination processing apparatus 200 on its side. In the following description, parts having the same functions as those of the above-mentioned apparatuses are given the same reference numbers, and the description of those parts will be omitted as appropriate. The sheet processing apparatus 100 or the lamination processing apparatus 200 has a paper feed tray 102 for stacking sheets S, and the inner pages P are configured so that they can be fed from the paper feed section 310 of the image forming apparatus 300, and any image can be printed on the inner pages P to be inserted between the sheets S using a method that utilizes the copy or printer of the image forming apparatus 300, and the inner pages P can be inserted inline.

[0081] In the sheet processing apparatus 100, a plurality of sensors C11 for detecting the size of the sheet S are arranged on the sheet tray 102, and conveying rollers 144 and 145 are provided before and after the heat and pressure roller 120.

[0082] FIG. 27 is a schematic diagram showing the configuration of an image forming system having an image forming apparatus 300, a relay apparatus 310, a sheet processing apparatus 100 or a lamination processing apparatus 200, and a post-processing apparatus 400. As shown in FIG. This image forming system is configured so that inner sheets P can be fed from the image forming device 300 via a relay device 310, and by installing another post-processing device 400 downstream of the image forming device 300, the user can use it without reducing the efficiency of print jobs that do not require lamination processing.

[0083] In the case of a print job that does not include lamination, the inner sheet P fed from the image forming apparatus 300 is received by the entrance rollers 146 of the sheet processing apparatus 100, and is transported to the post-processing apparatus 400 located downstream of the sheet processing apparatus 100 by the paper discharge rollers 147 located downstream of the entrance rollers 146 in the transport direction. The post-processing apparatus 400 can perform post-processing such as stapling on the sheet material N that has not been subjected to lamination. The inner sheet P is stacked in the paper discharge tray 150 of the post-processing apparatus 400.

[0084] In the sheet processing apparatus 100, a plurality of sensors C11 for detecting the size of the sheet S are arranged on the sheet tray 102, and conveying rollers 144 and 145 are provided before and after the heat and pressure roller 120.

[0085] The embodiment described in relation to Figures 16 to 23 in which multiple cleaning sheets are transported and the subsequent cleaning sheet is transported at a position different from the position perpendicular to the transport direction of the preceding cleaning sheet can also be implemented in the device configurations described in Figures 24 to 27.

[0086] Next, the series of operations in which multiple cleaning sheets are transported, the subsequent cleaning sheet is transported to a position different from the position perpendicular to the transport direction of the preceding cleaning sheet, and the cleaning sheet is moved and transported to the end position of the heat and pressure roller 120, thereby cleaning the entire roller, will be explained using the flowcharts shown in Figures 28 to 31.

[0087] FIG. 28 is a flow chart showing a series of operations (pre-transport position movement) for moving the position of the cleaning sheet in the main scanning direction before the cleaning sheet is transported using the paper feed tray 102 in the device configuration shown in FIGS. When the cleaning operation starts, the sheet processing apparatus 100 starts the movement operation of the inner sheet P (cleaning sheet) in step S11 (see FIG. 17), and then determines whether the edge of the inner sheet P (cleaning sheet) has reached the paper edge detection sensor C6 in step S12. If the edge has reached the paper edge detection sensor C6 (S12, Yes), the sheet processing apparatus 100 starts the feeding operation of the inner sheet P (cleaning sheet) in step S13 (see FIGS. 18 and 20). Next, the sheet processing apparatus 100 determines whether the leading edge of the inner sheet P (cleaning sheet) has reached the transport sensor C1 in step S14. If the leading edge has reached the transport sensor C1 (S14, Yes), the sheet processing apparatus 100 transports the inner sheet P (cleaning sheet) a specified amount (S15, Yes), and then starts transporting the inner sheet P (cleaning sheet) by the inlet roller pair 108 in step S16.

[0088] Next, when the leading edge reaches the transport sensor C3 (S17, Yes), the sheet processing apparatus 100 transports the inner sheet P (cleaning sheet) a specified amount (S18, Yes), and then in step S19 starts transporting by the exit roller pair 113. Next, when the leading edge reaches the transport sensor C5 (S20, Yes), the sheet processing apparatus 100 transports the inner sheet P (cleaning sheet) a specified amount (S21, Yes), and then in step S22 switches the branch claw 118 to switch the transport path to the fixing path 128, and in step S23 transports the inner sheet P (cleaning sheet) to a fixing section having a heat and pressure roller 120. As a result, the inner sheet P (cleaning sheet) cleans an area including one end of the heat and pressure roller 120.

[0089] If the cleaning operation has been performed the designated number of times (S24, Yes), the operation ends. If the cleaning operation has not been performed the designated number of times (S24, No), the sheet processing apparatus 100 moves the next inner sheet P (cleaning sheet) in step S25 (see FIG. 19). Next, in step S26, it is determined whether the edge of the inner sheet P (cleaning sheet) has reached the paper edge detection sensor C7. If the edge has reached the paper edge detection sensor C7 (S26, Yes), the sheet processing apparatus 100 returns to the flow shown in [1] and repeats steps S13 and onwards until the cleaning operation ends. By being transported at the position detected by the paper edge detection sensor C7, the inner sheet P (cleaning sheet) also cleans the area including the other edge of the heat and pressure roller 120.

[0090] Fig. 29 is a flow chart showing a series of operations (pre-transport position movement) for moving the position of the cleaning sheet in the main scanning direction before the cleaning sheet is transported using paper feed tray 102 in the device configuration shown in Fig. 21 and Fig. 24. Similar operations are performed in the case of paper feed tray 103, so a description thereof will be omitted. When the cleaning operation starts, the sheet processing apparatus 100 judges in step S31 whether the transported object stacked in the paper feed tray 102 is a sheet S or an inner sheet P (cleaning sheet) (see FIG. 25). If the transported object is not an inner sheet P (cleaning sheet) (S32, No), the cleaning operation ends (S33). If the transported object is an inner sheet P (cleaning sheet) (S32, Yes), the sheet processing apparatus 100 starts the movement operation of the inner sheet P (cleaning sheet) in step S34 (see FIG. 17), and then judges in step S35 whether the edge of the inner sheet P (cleaning sheet) has reached the paper edge detection sensor C6. If the edge has reached the paper edge detection sensor C6 (S35, Yes), the sheet processing apparatus 100 starts the feeding operation of the inner sheet P (cleaning sheet) in step S36 (see FIGS. 18 and 20). Next, the sheet processing apparatus 100 determines whether the leading edge of the inner sheet P (cleaning sheet) reaches the transport sensor C1 in step S37. If the leading edge reaches the transport sensor C1 (S37, Yes), the sheet processing apparatus 100 transports the inner sheet P (cleaning sheet) a specified amount (S38, Yes), and then starts transport by the inlet roller pair 108 in step S39.

[0091] Next, when the leading edge reaches the transport sensor C3 (S40, Yes), the sheet processing apparatus 100 transports the inner sheet P (cleaning sheet) a specified amount (S41, Yes), and then in step S42 starts transporting by the exit roller pair 113. Next, when the leading edge reaches the transport sensor C5 (S43, Yes), the sheet processing apparatus 100 transports the inner sheet P (cleaning sheet) a specified amount (S44, Yes), and then in step S45 switches the branch claw 118 to switch the transport path to the fixing path 128, and in step S46 transports the inner sheet P (cleaning sheet) to a fixing section having a heat and pressure roller 120. As a result, the inner sheet P (cleaning sheet) cleans an area including one end of the heat and pressure roller 120.

[0092] If the cleaning operation has been performed the designated number of times (S47, Yes), the operation ends. If the cleaning operation has not been performed the designated number of times (S47, No), the sheet processing apparatus 100 moves the next inner sheet P (cleaning sheet) in step S48 (see FIG. 19). Next, in step S49, it is determined whether the edge of the inner sheet P (cleaning sheet) has reached the paper edge detection sensor C7. If the edge has reached the paper edge detection sensor C7 (S49, Yes), the sheet processing apparatus 100 returns to the flow shown in [2] and repeats steps S36 and after until the cleaning operation ends. By transporting the inner sheet P (cleaning sheet) to the position detected by the paper edge detection sensor C7, the inner sheet P also cleans the area including the other edge of the heat and pressure roller 120.

[0093] FIG. 30 is a flow chart showing an embodiment in which the position of the cleaning sheet in the main scanning direction is moved by moving the pair of exit rollers 113 in the main scanning direction after feeding in the device configuration shown in FIGS. When the cleaning operation starts, the sheet processing apparatus 100 starts the feeding operation of the inner sheet P (cleaning sheet) in step S51, and then determines whether the leading edge of the inner sheet P (cleaning sheet) has reached the transport sensor C1 in step S52. If the leading edge has reached the transport sensor C1 (S52, Yes), the sheet processing apparatus 100 transports the inner sheet P (cleaning sheet) a specified amount in step S53 (S53, Yes), and then starts transporting the inner sheet P (cleaning sheet) by the inlet roller pair 108 in step S54.

[0094] Next, after the leading edge reaches the transport sensor C3 (S55, Yes), the sheet processing apparatus 100 performs a tilt correction operation using the exit roller pair 113 in step S57. Next, the sheet processing apparatus 100 starts transporting the inner sheet P (cleaning sheet) by the exit roller pair 113 in step S58. Next, when the leading edge reaches the transport sensor C5 (S59, Yes), the sheet processing apparatus 100 transports the inner sheet P (cleaning sheet) a specified amount (S60, Yes) and stops transport by the exit roller pair 113 (S61). Next, the sheet processing apparatus 100 detects a correction amount in the main scanning direction of the sheet by the paper edge detection sensor C10 in step S62. Next, the sheet processing apparatus 100 moves the exit roller pair 113 in the main scanning direction in step S63, transports the inner sheet P (cleaning sheet) a specified amount to shift the lateral registration (S64, Yes), and stops the movement of the exit roller pair 113 in the main scanning direction in step S65 (see FIG. 22).

[0095] Next, in step S66, conveyance by the exit roller pair 113 is started, and when the leading edge reaches the conveyance sensor C5 (S67, Yes), the sheet processing apparatus 100 conveys the inner sheet P (cleaning sheet) a specified amount (S68, Yes). Next, in step S69, the sheet processing apparatus 100 switches the branch claw 118 to switch the conveyance path to the fixing path 128, and in step S70, conveys the inner sheet P (cleaning sheet) to the fixing unit. If the cleaning operation has been performed the specified number of times (S71, Yes), the operation ends. If the cleaning operation has not been performed the specified number of times (S71, No), the sheet processing apparatus 100 returns to the flow shown in [3], and repeats steps S51 and onwards until the cleaning operation ends.

[0096] Fig. 31 is a flow chart showing an embodiment in which the position of the cleaning sheet in the main scanning direction is moved by moving the pair of exit rollers 113 in the main scanning direction after feeding in the device configuration shown in Fig. 21 and Fig. 24. The same operation is performed in the case of the paper feed tray 103, so a description thereof will be omitted. When the cleaning operation starts, the sheet processing apparatus 100 judges in step S81 whether the object stacked in the paper feed tray 102 is a sheet S or an inner sheet P (cleaning sheet) (see FIG. 25). If the object is not an inner sheet P (cleaning sheet) (S82, No), the cleaning operation ends (S83). If the object is an inner sheet P (cleaning sheet) (S82, Yes), the sheet processing apparatus 100 starts the movement operation of the inner sheet P (cleaning sheet) in step S84. Next, the sheet processing apparatus 100 judges in step S85 whether the leading edge of the inner sheet P (cleaning sheet) has reached the conveying sensor C1. If the leading edge has reached the conveying sensor C1 (S85, Yes), the sheet processing apparatus 100 conveys the inner sheet P (cleaning sheet) a specified amount in step S86 (S86, Yes), and then starts conveying the inner sheet P (cleaning sheet) by the inlet roller pair 108 in step S87.

[0097] Next, when the leading edge reaches the transport sensor C3 (S88, Yes) and the inner sheet P (cleaning sheet) is transported a specified amount (S89, Yes), the sheet processing apparatus 100 performs a tilt correction operation using the exit roller pair 113 in step S90 (see FIG. 21). Next, the sheet processing apparatus 100 starts transporting the inner sheet P (cleaning sheet) by the exit roller pair 113 in step S91. Next, when the leading edge reaches the transport sensor C5 (S92, Yes), the sheet processing apparatus 100 transports the inner sheet P (cleaning sheet) a specified amount (S93, Yes) and stops transport by the exit roller pair 113 (S94). Next, the sheet processing apparatus 100 detects a correction amount in the main scanning direction of the sheet by the paper edge detection sensor C10 in step S95. Next, the sheet processing device 100 moves the exit roller pair 113 in the main scanning direction in step S96, transports the inner sheet P (cleaning sheet) a specified amount to shift the lateral registration (S97, Yes), and then stops the movement of the exit roller pair 113 in the main scanning direction in step S98 (see FIG. 22).

[0098] Next, in step S99, conveyance by the pair of exit rollers 113 is started, and when the leading edge reaches the conveyance sensor C5 (S100, Yes), the sheet processing apparatus 100 conveys the inner sheet P (cleaning sheet) a specified amount (S101, Yes). Next, in step S102, the sheet processing apparatus 100 switches the branch claw 118 to switch the conveyance path to the fixing path 128, and in step S103, conveys the inner sheet P (cleaning sheet) to the fixing unit. If the cleaning operation has been performed the specified number of times (S104, Yes), the operation is terminated. If the cleaning operation has not been performed the specified number of times (S104, No), the sheet processing apparatus 100 returns to the flow shown in [4], and repeats steps S81 and onward until the cleaning operation is completed.

[0099] As described above, according to the lamination processing device of the embodiment of the present invention, a plurality of cleaning sheets are conveyed, and the succeeding cleaning sheet is conveyed to a position different from the position perpendicular to the conveying direction of the preceding cleaning sheet, thereby reducing the time and labor required for cleaning the fixing unit.
