Description

[Technical Field]

[0001] The present invention relates to a sheet processing apparatus and an image forming system. [Background technology]

[0002] There is a technique called lamination, in which a middle sheet to be sandwiched is sandwiched between two sheets that are connected on one side, and the two sheets are bonded together by applying heat and pressure, sandwiching the middle sheet inside. For example, Patent Document 1 discloses a sheet processing configuration in which two sheets are peeled apart and the middle sheet is inserted. However, when two sheets or a middle sheet are jammed, if you try to remove the jam from the front (side) of the device, you have to reach into a very small space, which makes it difficult to work. Summary of the Invention [Problem to be solved by the invention]

[0003] The present invention aims to improve the workability of jam clearance in a sheet processing device that inserts an intermediate sheet between two sheets of a polymerized sheet that is made by overlapping two sheets and joining one end side of the sheet as a joint. [Means for solving the problem]

[0004] In order to solve the above-mentioned problems, the sheet processing apparatus of the present invention comprises: a processing section for inserting an intermediate sheet between two sheets of a polymerized sheet having one end joined as a joint; a first supply unit disposed above the processing unit and supplying one of the polymerized sheet and the intermediate sheet; an opening / closing unit disposed above the processing unit and capable of opening the processing unit; The first supply unit is movable to open the processing unit. [Effects of the Invention]

[0005] According to the present invention, in a sheet processing apparatus that inserts an intermediate sheet between sheets of a polymerized sheet, the workability of jam clearance can be improved. [Brief explanation of the drawings]

[0007] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. In each of the drawings for explaining the embodiments of the present invention, components such as members and components having the same function or shape are designated by the same reference numerals as far as they can be distinguished, and descriptions thereof will be omitted once they have been described.

[0008] One aspect of a sheet processing apparatus according to an embodiment of the present invention includes a processing section (sheet processing section 10) that inserts an intermediate sheet between two overlapping sheets of a polymerized sheet formed by joining one end of the overlapping sheets, and a first supply section (first paper feed tray 20) that is disposed above the processing section and feeds one of the overlapping sheets and the intermediate sheet, and the first supply section is movable so as to open the processing section. ( ) The parentheses correspond to the configuration of Figure 1 described later as an example. A detailed description will be given below with reference to the drawings.

[0009] Embodiment 1. FIG. 1 is a diagram illustrating an example of the configuration of a sheet processing apparatus according to a first embodiment of the present invention. FIG. 2 is a diagram illustrating an example of a state when the sheet processing apparatus performs jam processing. The sheet processing device 100 includes a sheet processing device 10 as a processing device, a first paper feed tray 20 as a first supply device, a second paper feed tray 30 as a second supply device, a jam processing cover 40 as an opening / closing device, a peeling guide plate 50 as a peeling guide member, and a paper output tray 60.

[0010] The sheet processing section 10 peels off a polymerized sheet (such as a laminate film or pouch film) made by overlapping two sheets and joining one end of the sheet together, and inserts an inner sheet (such as paper or a photograph). Within the sheet processing section 10, the winding roller 1 and its surroundings are the inner sheet insertion section (also referred to as the "insertion section"), and the section centered around the fixing roller 5 is the laminate fixing section. The middle inserting section inserts the middle sheet between the sheets of the polymerized sheet. The laminating fixing section fixes the polymerized sheet in a laminating manner.

[0011] The first paper feed tray 20 supplies either a superposed sheet or an intermediate sheet. The second paper feed tray 30 supplies the other of the overlapping sheet and the intermediate sheet. In the following explanation, the first paper feed tray 20 will be described as feeding the overlapping sheets and the second paper feed tray 30 as feeding the middle sheets, but the sheet processing device of the present invention is effective in both cases where the first paper feed tray 20 feeds the overlapping sheets and the second paper feed tray 30 feeds the middle sheets, and where the first paper feed tray 20 feeds the middle sheets and the second paper feed tray feeds the overlapping sheets. When there is no need to distinguish between the polymer sheet and the inner sheet, they will be referred to as "sheet" as appropriate. Furthermore, the "polymer sheet" will also be referred to as "film" and the "intermediate sheet" will also be referred to as "intermediate paper."

[0012] The jam treatment cover 40 is a cover that covers the sheet processing section 10 . The peeling guide plate 50 guides the film from which the polymerized sheet has been peeled to the sheet insertion section.

[0013] The first paper feed tray 20 is supported by a rotation fulcrum 21 and, as shown in FIGS. 1 and 2, rotates clockwise and can be lifted upward. In addition, the jam processing cover 40 is supported by another pivot fulcrum 41 and is configured to rotate clockwise in the same manner as the first paper feed tray 20 to open and close the space above the sheet processing section 10. The user can ensure a wide access path to the sheet processing section by lifting the first paper feed tray 20 and then lifting the jam processing cover 40.

[0014] The arrow P in Figure 2 indicates the access route to the inner paper insertion section, which can be used to deal with problems such as jams or breakdowns that occur in or around the winding roller 1. This improves operability by opening the sheet insertion section, which has a complex mechanism. Additionally, arrow Q indicates the access route to the laminating fixing section, which can be used to deal with problems such as jams or breakdowns that occur in the film after the interleaf has been inserted in the laminating fixing section or its surrounding area. This improves operability by opening the laminating fixing section, which is otherwise complicated to deal with in the event of an abnormality.

[0015] As described above, by providing the openable / closable jam clearing cover 40 and configuring the first paper feed tray 20 to be movable, operations that previously required access from a narrow space in front of the sheet processing unit 10 can now be performed from a wide space above, providing good workability when clearing jams, performing maintenance, troubleshooting, etc. For example, when a polymerized sheet or an intermediate sheet jams and an attempt is made to clear the jam from the front of the device, it is necessary to reach into a very small space to access the winding roller 1 and the exit roller 3 that wrap and peel the film, which is a problem that makes work very difficult.

[0016] 1 and 2 show an example in which the first paper feed tray 20 and the jam clearing cover 40 rotate clockwise along an axis perpendicular to the paper surface, but this is not limiting; one or both may rotate counterclockwise, or a hinge may be provided on an axis parallel to the paper surface at the rear side as seen by the operator, or the cover may slide left and right or perpendicular to the paper surface to clear jams.

[0017] FIG. 3 is a diagram illustrating a peeling guide plate of the sheet processing apparatus. The peeling guide plate 50 is provided so as to be able to open the sheet processing section 10 (a part of the sheet processing section 10). In detail, the peeling guide plate 50 is supported on a rotation fulcrum 51 and rotates counterclockwise as shown by the arrow P, ensuring a wider access path to the inner paper insertion section. This makes it easier to work in the inner paper insertion section around the winding roller 1 and also makes it possible to clear jams that occur at the exit roller 3, thereby providing a sheet processing device with even greater ease of use.

[0018] In this embodiment, the first paper feed tray 20, jam recovery cover 40, and peeling guide plate 50 are rotatably supported by a rotation fulcrum, which allows the first paper feed tray 20 to be retracted and the jam recovery cover to be opened and closed as a natural action with a simple structure. This realizes a configuration with excellent usability at even lower cost.

[0019] In addition, the sheet processing apparatus 100 has a compact and space-saving configuration by arranging the first paper feed tray 20 above the sheet processing section 10 and the second paper feed tray 30 below it, which allows for a smaller installation area. For example, in a sheet processing device in which the feed tray for either film or paper is installed at the top of the sheet processing mechanism, if a second feed tray is installed on the right side of the device to feed the other sheet horizontally from the right of the device, the overall width of the device would become very large. As shown in Figure 1, the sheet processing device 100 can keep its overall width small by installing the second feed tray 30 at the bottom of the sheet processing unit 10 so that it has a turning portion similar to that of the first feed tray 20.

[0020] Embodiment 2. In this embodiment, a modified version of the jam receptacle cover of the first embodiment will be described. FIG. 4 is a diagram illustrating an example of the configuration of a sheet processing apparatus according to the second embodiment. FIG. 5 is a diagram illustrating an example of a state when the sheet processing apparatus performs jam processing at the inner sheet insertion portion. As shown in Figures 4 and 5, the sheet processing device 100A of this embodiment provides the opening and closing function performed by the jam processing cover 40A to the first paper feed tray 20A, and by integrating the opening and closing function with the first paper feed tray, it is possible to improve workability.

[0021] In more detail, the sheet processing apparatus 100A has a jam recovery cover 40A integrated with the first paper feed tray 20A, so that when clearing a jam, an access path is secured simply by lifting the first paper feed tray 20A. This eliminates the need for double operations, making the work easier. Furthermore, compared to separate installations, the number of hinges and other parts used as the pivot point for the jam recovery cover 40 can be reduced, resulting in reduced costs and weight.

[0022] Embodiment 3. In this embodiment, a modification of the function of the first paper feed tray or the like in the first embodiment to open the sheet processing section will be described. FIG. 6 is a diagram illustrating an example of the configuration of a sheet processing apparatus according to the third embodiment. The sheet processing device 100B has a detachable first paper feed tray 20B, a jam clearing cover 40B, and a peeling guide plate 50B. This configuration allows for a wide opening for jam clearing with a simple structure and a small number of parts, making access easier and providing better jam clearing performance.

[0023] 6 illustrates an example in which the first paper feed tray 20B, the jam treater cover 40B, and the peeling guide plate 50B are detachable, but at least one of these may be detachable and the others may be rotatable about a rotational fulcrum. The sheet processing apparatus may have, for example, a configuration including the first paper feed tray 20 rotatable about the rotational fulcrum 21 shown in FIG. 1, and the detachable jam treater cover 40B and the peeling guide plate 50B shown in FIG. Although the present embodiment has been described using the sheet processing apparatus 100 of embodiment 1, one or both of the first paper feed tray 20A and the peeling guide plate 50A of the sheet processing apparatus 100A of embodiment 2 can also be made detachable. By making the first paper feed tray 20A detachable, the function of the opening and closing section can also be made detachable.

[0024] Embodiment 4. In this embodiment, a description will be given of means for restricting sheets placed on the first sheet feed tray 20, 20A, etc. First, with reference to FIG. Fig. 7 is a diagram illustrating a state in which the first paper feed tray 20A has been rotated more than in the state shown in Fig. 5, with the sheets positioned approximately vertical. Fig. 7 shows a cross section of the first paper feed tray 20A near the center in the width direction. The width direction is defined as a direction perpendicular to the paper feed direction. Fig. 7 uses the first paper feed tray 20A shown in Fig. 5, but the same applies to the first paper feed trays 20 and 20B shown in Figs. 1, 6, etc.

[0025] The first paper feed tray 20A is provided with a pair of side fences that guide the sheet edges parallel to the feed direction of the sheets 24 and regulate the sheet edges parallel to the feed direction (regulating so-called lateral registration). In Fig. 7, the side fence 23a is installed on the first paper feed tray 20A behind the sheets 24, but does not regulate the sheet plane, so the rear end of the sheet may droop as shown by arrow R, causing feeding problems or, more seriously, falling off the first paper feed tray 20A and causing injury to the user.

[0026] Furthermore, not only in the case of Figure 7 but also in the cases of Figures 2, 3 and 5, when clearing a jam, it is necessary to hold down the first paper feed tray 20, 20A, 20B with one hand to stop it midway through the process, which raises concerns about reduced workability due to one hand being occupied.

[0027] FIG. 8 is a diagram illustrating an example of the first sheet feed tray of the sheet processing apparatus of the fourth embodiment, as viewed from the arrow A shown in FIG. Fig. 9 is a diagram for explaining an example of the first sheet feed tray of the sheet processing apparatus, showing a state as seen from arrow B shown in Fig. 7. Arrow B shown in Fig. 8 also shows the same direction as Fig. 7. 8 and 9 show the vicinity of the first sheet feed tray 20A of the sheet processing apparatus 100C, and omit other parts.

[0028] A pair of side fences 23a, 23b provided on the first paper feed tray 20A move as shown by the two arrows S in Figures 8 and 9, respectively, and are connected by a gear train (not shown) so that they move symmetrically left and right as shown in Figures 8 and 9.

[0029] In this embodiment, the sheet processing apparatus 100C has side fences 23a and 23b each having a sheet holding portion 25 for holding the sheet flat. In Figures 8 and 9, the pair of side fences 23a and 23b are shown with the back side as side fence 23a and the front side as side fence 23b when viewed from the front of the sheet processing apparatus 100C. The sheet holding portion 25 is provided, for example, so as to surround the upper side of the sheet 24, and preferably surrounds at least a portion of the upper side of the sheet 24, and preferably surrounds the edge of the sheet parallel to the paper feed direction. This prevents the trailing edge of the sheet 24 from drooping as shown in Figure 7, and further prevents the sheet 24 from falling out of the first paper feed tray 20A. This allows the first paper feed tray 20A to rotate within a larger range, making jam clearance even easier.

[0030] Furthermore, a stopper member that prevents the first paper feed tray 20A from rotating due to its own weight may be used as a pivot point. In the sheet processing apparatus 100C of this embodiment, torque hinges 21C are provided on two left and right sides for rotation around a rotation shaft 22 as an example of a stopper member. The torque hinges 21C temporarily prevent the first paper feed tray 20A from rotating in the falling direction due to its own weight, allowing it to pause at an appropriate predetermined angle. This eliminates the need to constantly hold the first paper feed tray 20A in one's hand when clearing a jam, allowing the jam to be cleared with both hands. This also has the effect of preventing accidents such as hands being pinched when the first paper feed tray 20A falls forcefully due to its own weight.

[0031] The pivot point is not limited to a configuration in which a torque hinge 21C is provided as in this embodiment, but a similar effect can be achieved by using a mechanism that temporarily suppresses the rotation of the first paper feed tray 20A and stops it in a predetermined position, such as a configuration using a bending lever element or the adhesive force of a magnet.

[0032] Next, another example of preventing the sheet from falling off will be described. FIG. 10 is a diagram for explaining another example of the first sheet feed tray of the sheet processing apparatus of the fourth embodiment, and shows a state seen from the arrow A shown in FIG. Fig. 11 is a diagram for explaining another example of the first sheet feed tray of the sheet processing apparatus, and shows the state as seen from arrow B shown in Fig. 7. Arrow B shown in Fig. 10 also indicates the same direction as Fig. 7. 10 and 11 show the vicinity of the first sheet feed tray 20A of the sheet processing apparatus 100D, and omit other parts.

[0033] The sheet processing apparatus 100D has a sheet holding cover 27 provided on the first sheet feed tray 20A. The cross-sectional shape of the sheet holding cover 27 is U-shaped as shown in Figure 11 and is positioned to surround the pair of side fences 23a, 23b and the sheet 24, preventing the sheet ends from drooping and the sheet 24 from falling even when the first paper feed tray 20A is nearly vertical as shown in Figure 7. Furthermore, it is preferable that the sheet holding cover 27 is made of a transparent or semi-transparent material, which allows the overall position of the sheet 24 to be visually grasped when setting the sheet, facilitating the setting work and improving workability.

[0034] Furthermore, the sheet retaining cover 27 can be installed on the first paper feed tray 20A to effectively prevent the sheets 24 from drooping, but if it is not possible to make it transparent or translucent due to cost or other reasons, the leading edge of the sheet may be hidden, making it difficult to see how far the sheet is inserted when loading, which may hinder loading. In such cases, it is advisable to devise a shape for the sheet retaining cover 27 to make it easier to load the sheets 24.

[0035] FIG. 12 is a plan view illustrating an example of the shape of the seat holding cover. FIG. 13 is a cross-sectional view illustrating an example of the shape of the seat holding cover. Fig. 12 is a plan view of the first paper feed tray 20A, and Fig. 13 is a cross-sectional view of the first paper feed tray near the center in the width direction as viewed from the front of the sheet processing apparatus. Figs. 12 and 13 show the first paper feed tray 20A and its vicinity of the sheet processing apparatus 100E, and omit other parts.

[0036] 12, a concave cutout 28 is provided on the lower edge of the sheet holding cover 27E in the figure. This makes it possible to directly see the vicinity of the leading edge of the sheet 24 and the paper feed roller 9 that grips the leading edge of the sheet. Therefore, even when surrounded by the sheet holding cover 27E, the positional relationship of the vicinity of the leading edge of the sheet can be grasped, and the sheet 24 can be easily set while checking the insertion depth when setting.

[0037] In this embodiment, the first paper feed tray 20A of the sheet processing device 100A of embodiment 2 has been described in Figures 8 to 13, but the same can be applied to the first paper feed tray 20 of the sheet processing device 100 of embodiment 1 and the first paper feed tray 20B of the sheet processing device 100B of embodiment 3.

[0038] The present invention is not limited to the above-described embodiments. Within the scope of the present invention, the elements of the above-described embodiments can be modified, added, or converted into contents that would be easily conceivable by a person skilled in the art. Furthermore, two or more embodiments may be combined as appropriate. [Explanation of symbols]
