Description

The present invention relates to a sheet processing apparatus and an image forming system.

A sheet processing device that cuts or streaks a sheet material is known. The sheet processing device is used to produce a sticker, a card, or a developed form of a box-shaped three-dimensional object from a sheet material to which an image or a pattern is attached. A plurality of forms of the sheet processing apparatus are known.

For example, in a flatbed type sheet processing device, a processing tool (cutter tool or streak tool) is selectively pressed and separated from a sheet material fixed on a flat surface (table, etc.) while moving it two-dimensionally. Perform sheet processing. Therefore, in the flatbed type, a processing tool is pressed against a non-moving sheet material to cut or streak the sheet material, and two-dimensional processing is performed on the sheet material with an arbitrary trajectory.

Further, unlike the flatbed type, the sheet material transport type sheet processing apparatus processes the sheet material without fixing it at a specific position. More specifically, while moving the sheet material back and forth in a predetermined direction with respect to the machining tool, the machining tool is moved in a direction different from the reciprocating movement direction and brought into contact with and separated from each other at a predetermined position to provide two dimensions in an arbitrary trajectory. Processing is performed. The moving direction of the processing tool is a direction orthogonal to the reciprocating moving direction of the sheet material.

As a flatbed type sheet processing device, while transporting the sheet material and moving the processing tool relative to each other, the processing tool is selectively pressed and separated from the sheet material, so that the sheet material can be made into an arbitrary trajectory. A sheet processing apparatus that performs two-dimensional processing is known (see Patent Document 1).

Like the sheet processing apparatus disclosed in Patent Document 1, the conventional one performs a cutting process or a streaking process on a sheet material that is forwardly or reversely conveyed in a substantially horizontal direction. Therefore, in the conventional sheet processing apparatus, the dimension of the machining tool (width in the transport direction) and the dimension of the sheet material to be machined in the transport direction, which are the width on the upstream side and the width on the downstream side of the machining tool, are added. It is necessary to secure an area corresponding to the specified dimensions. That is, in the conventional sheet processing apparatus, a region (space) that enables reciprocating transfer of the sheet material is secured on the upstream side and the downstream side in the transfer direction with dimensions corresponding to the size (width) of the sheet material to be processed. There is a problem in miniaturization of the entire device, particularly in the depth direction (reciprocating transport direction).

Further, there is also a problem that the user's operability with respect to the sheet material is lowered by increasing the depth dimension of the device according to the size (width) of the sheet material.

An object of the present invention is to reduce the size and improve operability of a sheet processing apparatus capable of two-dimensionally sheet processing.

In order to solve the above technical problems, one aspect of the present invention is a sheet processing device for processing a sheet material, which is a processing tool for processing the sheet material and a processing tool for bringing the processing tool into contact with the sheet material. A transport means including a contact / detachment portion and a transport path for transporting the sheet material relative to the processing tool is provided, and the reciprocating transport direction of the sheet material by the transport means is relative to a horizontal plane. The processing tool contact / detachment portion includes the direction of inclination, and is characterized in that the processing tool is brought into contact with the sheet material in an inclined state conveyed in the inclined direction with respect to the horizontal plane.

According to the present invention, in a sheet processing apparatus capable of two-dimensionally sheet processing, it is possible to reduce the size and improve the operability.

[Overall configuration of sheet processing equipment]
Hereinafter, embodiments of the sheet processing apparatus according to the present invention will be described with reference to the drawings. FIG. 1 is a perspective view showing the appearance of the processing apparatus 100 according to the present embodiment. As shown in FIG. 1, the processing apparatus 100 includes a carry-in side tray 101 that constitutes a carry-in inlet for a sheet material (cut sheet S) that is a sheet-shaped object to be processed, and a carry-out outlet for the cut sheet S after processing. The carry-out side tray 102 and the like.

Here, the coordinate system used for the description of the present embodiment is defined. Assuming a surface (mounting surface) on which the processing apparatus 100 is mounted, the direction in which the processed cut sheet S is carried out in parallel with the mounting surface is defined as the Z direction. Further, the direction parallel to the mounting surface and intersecting the Z direction is defined as the X direction. Then, the direction orthogonal to the X direction and the Z direction is defined as the Y direction. The X direction corresponds to the width direction of the cut sheet S to be processed, as will be described later.

As shown in FIG. 1, the direction in which the cut sheet S before processing is carried into the processing apparatus 100 (arrow Pi) is a direction that is inclined with respect to the Y direction and intersects the XZ plane. The X direction is the width direction of the cut sheet S (the width direction of the processing apparatus 100).

[Delivery side tray 101]
A plurality of cut sheets S are loaded and held as a bundle of sheets on the carry-in side tray 101 as a sheet material loading part, and when the sheet processing process is started, the cut sheets S are separated from the carry-in side tray 101 one by one. It is carried in the direction of the arrow Pi in FIG. The cut sheet S for which the sheet processing process has been completed is carried out in the direction of the arrow Po on the carry-out side tray 102. The carry-in side tray 101 also constitutes a sheet material carry-in portion.

The carry-in side tray 101 constitutes a part of the transport means for transporting the cut sheet S to the processing tool 105 described later, and forms a part of the transport path.

As shown in FIG. 1, the carry-in side tray 101 holds the cut sheet S in an inclined state (inclined state) with respect to the mounting surface of the processing apparatus 100. This tilted state is, for example, 45 degrees or more and 90 degrees or less with respect to the mounting surface. That is, the cut sheet S is carried in from the sheet bundle loaded on the carry-in side tray 101 in a state of maintaining an inclined posture having a predetermined angle with respect to the mounting surface, and then the cut sheet S is brought into the processing tool 105. On the other hand, it is transported back and forth.

The sheet material loading section serves as a separating transporting means for separating the cut sheets S one by one from the sheet bundle loaded on the loading side tray 101 as the sheet material loading section in an inclined state and moving them to the transport path. It has a pickup roller 210 (see FIG. 2).

Further, as shown in FIG. 1, the sheet material loading section has a side fence 103 as a regulating member for regulating the positions of a plurality of cut sheets S loaded on the loading side tray 101 in the width direction. There is. The side fence 103 can prevent the cut sheet S, which is separated and carried in, from skewing in the transport direction.

When the user operates the processing apparatus 100, the user faces the processing apparatus 100 from the side in the Z direction. Therefore, the Z direction also corresponds to the depth direction of the processing apparatus 100. When the user operates the processing apparatus 100, the processing apparatus 100 may face the processing apparatus 100 from the X direction side. In that case, the X direction corresponds to the depth direction of the processing apparatus.

In the following, the embodiments will be described assuming that the X direction, the Y direction, and the Z direction are orthogonal to each other.

As shown in FIG. 1, the processing apparatus 100 also includes a control apparatus 300 that controls the overall operation.

In the present embodiment, the movement (conveyance) of the cut sheet S during sheet processing is reciprocating transportation with respect to the processing tool 105. The direction of this reciprocating transport is the vertical direction (Y direction). By setting the moving direction (conveying direction) of the cut sheet S during sheet processing to the direction (Y direction) perpendicular to the mounting surface (XX plane) of the processing device 100, the depth direction (Y direction) of the processing device 100 ( The dimension in the Z direction) can be shortened. That is, the processing apparatus 100 according to the present embodiment can be miniaturized.

The reciprocating transport direction of the cut sheet S during sheet processing in the processing apparatus 100 is not limited to the vertical direction (Y direction). The reciprocating transport direction of the cut sheet S at the time of sheet processing may be a substantially vertical direction or an inclined direction in which the cut sheet S is inclined at a predetermined angle with respect to the XZ plane. Also in this case, the depth dimension (dimension in the Z direction) of the processing apparatus 100 is shortened as compared with the conventional example in which the reciprocating transport direction of the cut sheet S is the direction along the mounting surface of the processing apparatus 100, and the entire apparatus. Can be miniaturized.

As the reciprocating transport direction of the cut sheet S during processing is closer to vertical, the effect of miniaturization in terms of depth dimension can be further obtained. That is, in the processing apparatus 100, the degree of inclination of the cut sheet S in the reciprocating transport direction during sheet processing increases as the degree of inclination in the reciprocating transport direction becomes closer to vertical, and therefore the effect on miniaturization of the apparatus increases. It is preferable to have.

In the processing apparatus 100 according to the present embodiment, the user sets the cut sheet S as a sheet bundle in the carry-in side tray 101. Therefore, in order for the user to access the processing apparatus 100, it is desirable to make the depth dimension (dimension in the Z direction) particularly small.

[Internal structure of processing apparatus 100]
Next, the internal structure of the processing apparatus 100 will be described. FIG. 2 is a cross-sectional view showing the internal structure of the processing apparatus 100. The cross-sectional view of FIG. 2 illustrates a cross section parallel to the YY plane in FIG.

As shown in FIG. 2, the processing apparatus 100 includes a processing tool 105, which is a processing tool for performing sheet processing on the cut sheet S, a processing tool contact / detachment portion 110, a processing tool moving portion 120, and a processing tool facing each other. A unit 130 is provided. Further, the processing apparatus 100 includes a transport roller pair 150 as a transport means for reciprocally transporting the cut sheet S to the processing tool 105. FIG. 2 shows only the first transport roller pair 151 arranged on the carry-in inlet side among the transport roller pairs 150 constituting the transport means.

The processing tool 105 is held by the processing tool contact / detachment portion 110. The machining tool 105 is arranged at a position (opposite position) facing the machining tool facing portion 130 with the cut sheet S in the state of being held by the machining tool contact / detaching portion 110.

The processing tool contact / detachment portion 110 holds a processing tool 105 such as a cutting tool (cutter) for cutting the cut sheet S and a scoring tool (crecer) for scoring at a predetermined position. Details of the processing tool 105 will be described later. Further, the machining tool contact / detachment portion 110 includes a machining tool contact / detachment moving mechanism that causes the machining tool 105 to come into contact with the cut sheet S and to separate the machining tool 105.

The processing tool moving unit 120 reciprocates the processing tool 105 in the X direction (intersection direction with the reciprocating transport direction) when the cut sheet S is subjected to sheet processing such as cutting or streaking. It is equipped with a mechanism (processing tool contact / detachment movement mechanism). The processing tool moving unit 120 reciprocates the processing tool 105 together with the processing tool contact / detachment portion 110.

In this embodiment, the X direction is a direction orthogonal to the transport direction of the cut sheet S at the machining position of the processing tool 105, and is a direction orthogonal to the Y direction (the transport direction of the cut sheet S). As shown in FIGS. 1 and 2, the height direction of the processing apparatus 100 is the Y direction. Therefore, the X direction is a direction orthogonal to the transport direction of the cut sheet S at the machining position of the machining tool 105 and the carry-out direction (Z direction) of the machining processing device 100, and corresponds to the width direction of the cut sheet S.

The processing tool facing portion 130 has a facing surface facing the processing tool 105, and includes a roller-shaped member as a rotating rotating member. The facing surface corresponds to a position where the processing tool 105 receives a pressing force applied to the cut sheet S corresponding to a processing position where the processing tool 105 moving in the X direction comes into contact with the cut sheet S, and the cut sheet S. It is a portion located at an opposite position facing the processing tool 105 with a. As shown in FIG. 2, the facing surface of the machining tool facing portion 130 corresponds to the same position as the machining tool 105 in the Y direction. In other words, the facing surface of the machining tool facing portion 130 is arranged in the direction perpendicular to the machining tool 105 (Z direction). In other words, the processing tool 105 is arranged in the direction perpendicular to the facing surface (Z direction) and is held by a configuration that does not move in the Y direction.

The processing apparatus 100 performs processing by reciprocating the cut sheet S in the Y direction by the transfer roller pair 150 and moving the processing tool 105 in the X direction. During this sheet processing, the processing tool 105 and the processing tool contact / detachment portion 110 do not move in the Y direction with respect to the processing tool facing portion 130, but move only in the X direction. That is, the control device 300 of the machining processing apparatus 100 controls to move or stop the machining tool 105 and the machining tool contact / detachment portion 110 in the X direction at the time of executing the sheet machining process, and at the selected timing. The operation is controlled by bringing the processing tool 105 into contact with or separating from the cut sheet S. By the above operation, the processing apparatus 100 can perform sheet processing on the cut sheet S while drawing a locus composed of an arbitrary plane free curve.

In the processing apparatus 100, the cut sheet S is reciprocated in a vertical, substantially vertical, or inclined state with respect to an XZ plane (may be a horizontal plane) by a transport roller pair 150 which is a transport means. Then, the processing tool contact / detachment portion 110 brings the processing tool 105 into contact with the cut sheet S in a vertical, substantially vertical, or inclined state to execute the sheet processing process.

The state of operation at the time of sheet processing in the processing apparatus 100 will be described. When the sheet processing process is started, the cut sheet S is called (carried in) into the processing device 100 by the pickup roller 210 from the sheet bundle set in the carry-in side tray 101. At the same time, one cut sheet S is separated from the sheet bundle by the separation pad facing the pickup roller 210.

The separated cut sheet S passes through the branch claw 201 and is transported to the first transport roller pair 151 as the transport means arranged near the carry-in inlet. The processing apparatus 100 according to the present embodiment separates sheets by a pad separation method as a separation and transfer means, but the method of separating and transporting the cut sheet S from the sheet bundle is not limited to this. It is also possible to apply the belt separation method or the FRR separation method.

When the rear end of the transported cut sheet S is transported until it passes through the branch claw 201, the branch claw 201 moves to the switchback 202 side, which is a transport path as a retracting portion. As a result, the sheet is processed while a part of the cut sheet S processed while reciprocating is taken in and out of the switchback 202.

Downstream of the processing tool facing portion 130, a part of the cut sheet S is conveyed to the carry-out side tray 102 while being curved along the curved transfer guide plate 203 forming a part of the transfer path. The curved transport guide plate 203 is a guide portion that forms a second transport path that is a part of the transport path, and is directed in a Z direction different from the Y direction, which is the transport direction of the cut sheet S with respect to the processing tool 105. It corresponds to a curved portion that conveys the end portion of the cut sheet S. That is, in the processing apparatus 100, the cut sheet S is reciprocally transported in the curved transport path including the curved transport guide plate 203 at the end on the downstream side in the transport direction during the sheet processing.

On the other hand, in the cut sheet S being processed for sheet processing, the end portion on the upstream side in the transport direction is reciprocally transported in the first transport path. The first transport path is a transport path that forms a part of the transport path and includes a switchback 202 and a guide portion arranged upstream of the curved transport guide plate 203 in the transport direction.

The cut sheet S subjected to the sheet processing process is carried out toward the carry-out side tray 102. The carry-out side tray 102 is arranged on the downstream side of the curved transport guide plate 203 in the transport direction, and forms a third transport path that forms a part of the transport path.

The processing tool 105 is arranged inside the curved transport guide plate 203 in the bending direction. Therefore, the processing apparatus 100 is configured to carry out the cut sheet S for which the sheet processing has been completed to the side where the processing tool 105 is arranged.

The transport means is configured by the transport path including the switchback 202, the curved transport guide plate 203, the carry-out side tray 102, and the transport roller pair 150. The transport means also includes a carry-in side tray 101.

Further, as shown in FIG. 2, the branch claw 201 is arranged on the downstream side in the transport direction from the carry-in side tray 101 constituting the sheet material carry-in portion and on the upstream side in the transport direction from the processing tool 105, and is arranged on the processing tool 105. The transport route (first transport route) between the and the carry-in side tray 101 is switched. The branch claw 201 constitutes a switching portion.

A part of the first transport path switched by the branch claw 201 is configured by the switchback 202. The switchback 202 retracts the upstream end of the cut sheet S being processed in the transport direction in a direction different from that of the carry-in tray 101. The switchback 202 constitutes a transport path (first transport path) in this evacuation direction. The switchback 202 constitutes a retractable portion having a support surface that guides the cut sheet S in a direction substantially perpendicular to the horizontal plane.

The first transport roller pair 151 is arranged at a position where the downstream end in the transport direction of the cut sheet S, which has been separated from the one loaded on the carry-in side tray 101 and has been transported, abuts. By this abutting, the resist correction of the cut sheet S is performed. With the cut sheet S abutting against the first transfer roller pair 151, the first transfer roller pair 151 rotates at a predetermined transfer timing, so that the machining position with respect to the machining tool 105 while the cut sheet S is skew-corrected. Is then reciprocated by a pair of rollers 150.

[Structure of main parts of processing apparatus 100]
FIG. 3 is a perspective view showing a main part of the internal structure of the processing apparatus 100. FIG. 4 is a side view showing the processing tool 105 and the processing tool contact / detachment portion 110 in the internal structure of the processing apparatus 100. FIG. 5 is an enlarged plan view of the drive source portion of the processing tool moving portion 120. FIG. 6 is an enlarged perspective view of a movement holding mechanism portion included in the processing tool moving portion 120. In FIG. 3, the transport roller pair 150 is omitted.

Hereinafter, the structure centered on the processing tool 105 included in the processing apparatus 100 will be described in detail. In each figure, it is assumed that the cut sheet S reciprocates in the Y direction.

[Structure of processing tool contact / detachment portion 110]
First, the configuration of the machining tool contact / detachment portion 110 will be described with reference to FIGS. 3 and 4. The machining tool contact / detachment portion 110 is a first contact separation between a cutter 111, which is a cutting tool constituting the machining tool 105, a creature 112, which constitutes a muscular tool, a first tool holder 113, and a second tool holder 114. The actuator 115 and the second contact separation actuator 116 are provided.

The cutter 111, which is the first processing tool, is a cutting tool that contacts the cut sheet S to perform cutting processing. The creaser 112, which is the second processing tool, is a scoring tool that presses the cut sheet S to perform scoring processing. The cutter 111 is held at a position facing the first opposed roller 131 as a processing tool facing portion. That is, the cutter 111 is arranged to face the first opposed roller 131. The cleaner 112 is held at a position facing the second opposed roller 132 as a processing tool facing portion. That is, the creature 112 is arranged to face the second opposed roller 132.

The first tool holder 113 connects and holds the first contact separation actuator 115 and the cutter 111. The second tool holder 114 connects and holds the second contact separation actuator 116 and the creature 112.

The first contact separation actuator 115 and the second contact separation actuator 116 are connected by a machining tool moving member 128 described later. The machining tool moving member 128 integrally holds the machining tool 105 (cutter 111 and creeper 112) in the machining tool contact / detachment portion 110, and is movable in the X direction.

The first contact separation actuator 115 and the second contact separation actuator 116 are, for example, solenoids. Therefore, by operating the first contact separation actuator 115 and the second contact separation actuator 116 (energizing the solenoid), the cut sheet S is moved between the first opposed roller 131 and the second opposed roller 132 by the processing tool 105. Form a state of sandwiching and holding. That is, by operating the first contact separation actuator 115 and the second contact separation actuator 116, the processing tool 105 can be pressed against the cut sheet S.

As described above, by controlling the operations of the first contact separation actuator 115 and the second contact separation actuator 116, the cutter 111 and the creature 112 can be selectively contacted or separated from the cut sheet S. Then, while the control device 300 controls the contact and separation of the cutter 111 and the creaser 112, the reciprocating transfer of the cut sheet S is also controlled, so that the processing into the cut sheet S is controlled.

As shown in FIG. 4, a first transfer roller pair 151 as a transfer means is arranged on the upstream side in the Y direction of the processing tool contact / detachment portion 110 that holds the processing tool 105. Further, a second transfer roller pair 152 as a transfer means is arranged on the downstream side in the Y direction of the processing tool contact / detachment portion 110 that holds the processing tool 105. The cut sheet S is reciprocally transported in the Y direction by these transport roller pairs 150 (first transport roller pair 151, second transport roller pair 152). The cut sheet S carried into the processing apparatus 100 from the upstream side in the transport direction (upstream side in the Y direction) is sandwiched between the first transport roller pair 151, and is driven by the forward / reverse rotation drive of the first transport roller pair 151 with respect to the machining position. It is transported back and forth and processed. After that, the processed cut sheet S is sandwiched between the second transport roller pair 152 and carried out.

As shown in FIG. 3, the first opposing roller 131 is provided with a first holding roller 133 that rotates in response to the first opposed roller 131. Further, a second sandwiching roller 134 that rotates in response to the second opposed roller 132 is arranged to face the second opposed roller 132. Both end portions of the cut sheet S are sandwiched by the first opposed roller 131 and the first sandwiching roller 133, and the second opposed roller 132 and the second sandwiching roller 134 as transport means, and reciprocate in the Y direction ( Will be transported). That is, when processing the cut sheet S, in addition to the transfer by the first transfer roller pair 151 and the second transfer roller pair 152, the first opposed roller 131 and the first holding roller 133, the second opposed roller 132 and the second holding roller 134 Round-trip transportation is also performed.

[Structure of processing tool moving part 120]
Next, the configuration of the processing tool moving portion 120 will be described with reference to FIGS. 3 and 5 and 6. The machining tool moving unit 120 includes an X-axis drive motor 121, an output timing pulley 122, a first timing belt 123, a deceleration timing pulley 124, a first machining tool moving pulley 125, a second timing belt 126, and a second machining. It includes a tool moving pulley 127, a machining tool moving member 128, and a machining tool moving guide shaft 129.

The X-axis drive motor 121 is a drive source capable of forward / reverse rotation for moving the processing tool contact / detachment portion 110 holding the cutter 111 and the creature 112 in a direction intersecting the transport direction (Y direction) of the cut sheet S. Is. The rotating shaft of the X-axis drive motor 121 is connected to the deceleration timing pulley 124 from the output timing pulley 122 via the first timing belt 123.

The deceleration timing pulley 124 is in contact with the first machining tool moving pulley 125 via a gear portion integrally formed. Therefore, when the deceleration timing pulley 124 is rotationally driven by the rotational drive of the X-axis drive motor 121, the first machining tool moving pulley 125 rotates via the gear portion.

As shown in FIGS. 5 and 6, the first machining tool moving pulley 125 and the paired second machining tool moving pulley 127 are connected by a second timing belt 126. Therefore, the second timing belt 126 hung between the first machining tool moving pulley 125 and the second machining tool moving pulley 127 is rotated by the rotation of the first machining tool moving pulley 125.

The processing tool moving member 128 sandwiches the second timing belt 126 and is fixed at a predetermined position of the second timing belt 126. Therefore, when the second timing belt 126 is rotated by the rotation of the first machining tool moving pulley 125 and the second machining tool moving pulley 127, the machining tool moving member 128 also moves according to the rotation direction. A machining tool movement guide shaft 129 is inserted through the machining tool moving member 128. The processing tool movement guide shaft 129 is a member extended in the X direction, and its end is fixed to the housing of the processing apparatus 100. Therefore, the machining tool moving member 128 is guided by the machining tool movement guide shaft 129 and moves only in the X direction by the rotation of the second timing belt 126, that is, by the rotation of the X-axis drive motor 121. Therefore, when the X-axis drive motor 121 rotates in the forward and reverse directions, the machining tool contact / detachment portion 110 connected and fixed to the machining tool moving member 128 intersects the transport direction of the cut sheet S (X direction). It is configured to move back and forth to. As a result, the processing tool 105 is held so as to be able to reciprocate in the direction (X direction) intersecting the transport direction of the cut sheet S.

[Structure of machining tool facing portion 130]
Next, the configuration of the processing tool facing portion 130 will be described with reference to FIG. The processing tool facing portion 130 includes a first facing roller 131, a second facing roller 132, a first holding roller 133 (133a, 133b), and a second holding roller 134 (134a, 134b). The first opposed roller 131 and the second opposed roller 132 are rotating members that are rotated in both the forward and reverse directions by a drive source such as an electric motor. The peripheral surfaces of the first opposed roller 131 and the second opposed roller 132 rotate in the conveying direction of the cut sheet S in synchronization with the conveying of the cut sheet S by the first conveying roller pair 151 and the second conveying roller pair 152. The first opposed roller 131 and the second opposed roller 132 are also driving rollers, and the first sandwiching roller 133 and the second sandwiching roller 134 are driven rollers that are rotated by the rotational drive of the driving roller.

The first holding roller 133 is pressurized in the −Z direction by the urging member so as to be pressed against the first opposed roller 131. The second holding roller 134 is pressurized in the −Z direction by the urging member so as to be pressed against the second opposing roller 132. Therefore, the cut sheet S at the time of processing is sandwiched between the first opposed roller 131 and the first sandwiching roller 133 (133a, 133b), and the second opposed roller 132 and the second sandwiching roller 134 (134a, 134b). It is configured. In FIG. 3, a part (134b) of the second holding roller 134 is hidden behind the processing tool contact / detaching portion 110 and is not shown.

When the cut sheet S is processed, the first opposed roller 131 and the second opposed roller 132, which are drive rollers, rotate in the forward and reverse directions, so that the cut sheet S at the time of processing is reciprocated in the Y direction. That is, the processing tool facing portion 130 constitutes a transport portion as a transport means for reciprocally transporting the cut sheet S in the Y direction. The cut sheet S is reciprocally conveyed between the cutter 111 and the first opposed roller 131 and between the creature 112 and the second opposed roller 132 by rotation control with respect to the machining tool facing portion 130.

The transport roller pair 150, various rotating members, and the X-axis drive motor 121 in the present embodiment are premised on a stepping motor, but any function capable of realizing the operations illustrated above can be obtained. , The type of drive source does not matter.

[Control configuration of processing apparatus 100]
Next, the control configuration of the processing apparatus 100 according to the present embodiment will be described with reference to FIGS. 7 and 8. FIG. 7 is a block diagram showing a hardware configuration related to the control system of the processing apparatus 100. FIG. 8 is a block diagram showing a functional configuration related to the control system of the processing apparatus 100.

As shown in FIG. 7, the control device 300 included in the processing device 100 includes a configuration similar to that of a general information processing device. That is, in the control device 300 according to the present embodiment, the CPU (Central Processing Unit) 310, the RAM (Random Access Memory) 320, the ROM (Read Only Memory) 330, the operation display panel 340, and the I / F 350 are connected via the bus 360. It is connected. Further, a cutter tool driver 351 and a scoring tool driver 352, a tool moving driver 353, and a sheet transfer driver 354 are connected to the I / F 350.

The CPU 310 is a calculation means and controls the operation of the entire information processing apparatus. The RAM 320 is a volatile storage medium capable of reading and writing information at high speed, and is used as a work area when the CPU 310 processes information. The ROM 330 is a read-only non-volatile storage medium, and stores firmware, a control program, and the like. The operation display panel 340 includes a display screen for displaying information for notifying the operating state of the processing apparatus 100 to the outside. Further, the operation display panel 340 provides an input interface for inputting a setting value or the like used for control.

The I / F 350 transmits to the driver that operates each functional configuration by the control signal generated by the arithmetic function of the CPU 310. The cutter tool driver 351 controls the contact / detachment operation of the cutter 111 with respect to the cut sheet S. The muscular tool driver 352 controls the movement of the creature 112 to and from the cut sheet S. The tool movement driver 353 controls the rotational operation of the X-axis drive motor 121 in the forward and reverse directions. The sheet transfer driver 354 controls the rotation operation of the first opposed roller 131 and the second opposed roller 132 and the rotation operation of the transfer roller pair 150.

[Functional configuration]
In the hardware configuration described above, the software control unit is configured by the CPU 310 executing arithmetic processing based on the program stored in the ROM 330. The combination of the software control unit configured in this way and the hardware configuration constitutes a functional block (see FIG. 8) that realizes the processing function of the processing apparatus 100 according to the present embodiment.

As shown in FIG. 8, the control unit 31 realized by the control device 300 of the machining processing device 100 includes a control means 311 for controlling the overall operation of the machining processing device 100, a cutter tool attachment / detachment means 312, and a streak. It has a tool attachment / detachment means 313, a tool moving means 314, and a seat moving means 315.

The tool moving means 314 controls the moving direction of the processing tool 105 in the X direction, the moving amount, the moving speed, and the timing of starting and stopping the movement.

The sheet moving means 315 controls the moving direction (transporting direction) of the cut sheet S in the Y direction, the moving amount, the moving speed, and the timing of starting and stopping the movement.

The cutter tool attachment / detachment means 312 contacts, presses, and separates the cutter 111 from the cut sheet S at a predetermined timing. The muscular tool attachment / detachment means 313 contacts, presses, and separates the creeper 112 from the cut sheet S at a predetermined timing.

Each of the above functional means is configured by a control unit 31 composed of a control program executed by the CPU 310, and each executes a control process. By this control process, the cutter 111 and the creeper 112 can be moved while conveying the cut sheet S, and the contact / separation operation can be selectively performed. By this contact / detachment operation, it is possible to arbitrarily draw a two-dimensional locus on the cut sheet S, perform streak processing at a desired position on the cut sheet S, and perform cutting processing in a desired shape.

The first facing roller 131 forming the facing surface of the cutter 111 and the second facing roller 132 forming the facing surface of the creature 112 are roller members made of an elastic body such as silicon rubber or EP rubber.

Here, the operation of the processing apparatus 100 will be described in detail. When machining in a direction orthogonal to the transport direction of the cut sheet S (first machining), the first facing roller 131 and the second facing roller 132 are held so as not to rotate. When processing in a direction other than the direction orthogonal to the transport direction of the cut sheet S (second machining), the first opposed roller 131 and the second opposed roller 132 are rotated in the direction in which the cut sheet S is conveyed. To do so. By performing the operation control in this way, the positions (parts) of the facing surfaces of the first facing roller 131 and the second facing roller 132, which are the receiving positions with respect to the processing tool 105, can be changed according to the transport direction of the cut sheet S. it can. As a result, when processing the cut sheet S in the width direction with the facing surface changed, the facing surface can be held so as not to move and stable processing can be performed.

If the facing surfaces cannot be moved as described above, the same parts (specific parts of the first facing roller 131 and the second facing roller 132) are always engaged with the cutter 111 and the creature 112. It will be. As a result, "sagging" such as wear and deformation of specific parts of the first facing roller 131 and the second facing roller 132 progresses at an early stage, and the durability of the first facing roller 131 and the second facing roller 132 is improved. It will deteriorate.

In this regard, according to the processing apparatus 100 according to the present embodiment, when processing (second processing) other than the direction orthogonal to the transport direction of the cut sheet S is performed, that is, the processing direction to the cut sheet S is the cut sheet. In the case of processing including the transport direction of S, at least the first opposed roller 131 facing the cutter 111 rotates so that the facing surface moves around at the same speed as the transport speed of the cut sheet S.

If the first opposed roller 131 is not rotated in synchronization with the conveying speed of the cut sheet S, the cut sheet S and the first opposed roller 131 are in contact with each other over the entire area in the sheet width direction, so that the first opposed roller 131 Will hinder the transport of the cut sheet S. If the transport of the cut sheet S is hindered, it is necessary to increase the transport force of the cut sheet S. Therefore, it is necessary to increase the size of the entire apparatus or to allow variations in the transport speed of the cut sheet S. If the transport speed of the cut sheet S varies, the processing accuracy will vary, so that the entire apparatus must be made large. In this regard, according to the processing apparatus 100 according to the present embodiment, since the first opposed roller 131 is rotated in synchronization with the movement of the cut sheet S, it is possible to assist the transportation of the cut sheet S during processing. It is possible to reduce the size of the device and realize sheet processing with an arbitrary two-dimensional locus with high accuracy.

[Detailed Embodiment of Creaser 112]
Next, the detailed configuration of the creature 112 will be described with reference to FIG. FIG. 9 is an enlarged side view of the tip portion of the creature 112. A tip member 112a is attached to the tip of the creature 112. The tip member 112a is a spherical member and is held at the tip portion of the creature 112. The tip member 112a comes into contact with and presses against the second opposing roller 132. Since the surface of the second opposed roller 132 has elasticity, it is dented by pressing the tip member 112a.

The creaser 112 moves in a two-dimensional direction relative to the cut sheet S with the cut sheet S sandwiched between the tip member 112a and the second opposed roller 132, so that any freedom to the cut sheet S can be obtained. It is possible to perform scoring processing consisting of trajectories including curves. During this scoring process, the tip member 112a moves with less friction according to the relative moving direction of the cut sheet S, so that the moving resistance of the creaser 112 during processing is reduced.

The tip member 112a is not limited to a spherical member, and may have a spherical shape that can rotate in any direction like the pen tip of a ballpoint pen. In this case, since the tip member 112a rotates according to the relative moving direction of the cut sheet S during the scoring process, it can be moved with less friction. Therefore, when the tip member 112a is composed of a ball-shaped member, the movement resistance of the creature 112 during processing is further reduced.

Further, as the tip member 112a, a pen tool such as a pencil or a ballpoint pen using ink may be used. In this case, during processing using the creaser 112, the tip member 112a moves according to the relative moving direction of the cut sheet S, and the visible line such as an image drawing including a free curve or a ruled line is cut on an arbitrary locus. It can be attached to S.

[Detailed Embodiment of Cutter 111]
Next, the detailed configuration of the cutter 111 will be described with reference to FIG. FIG. 10 is an enlarged side view of the tip portion of the cutter 111. A cutter blade 111a is held at the tip of the cutter 111. The cutter blade 111a is held so that the amount of protrusion can be changed, and the amount of protrusion of the cut sheet S in the thickness direction is controlled by the cutter tool contact / detachment means 312. For example, when the cut sheet S has a layer structure of a peeling seal layer Sa and a mount layer Sb, if the tip of the cutter blade 111a is projected by an amount corresponding to the thickness of the peeling seal layer Sa and processed, only the peeling seal layer Sa is processed. Can be disconnected.

Further, the cut sheet S can be cut by protruding the tip of the cutter blade 111a by an amount corresponding to the thickness of the release seal layer Sa and the mount layer Sb.

Further, the tip of the cutter blade 111a is intermittently controlled so as to project an amount equivalent to the thickness of the peeling seal layer Sa and a protruding state corresponding to the thickness of the peeling seal layer Sa and the mount layer Sb, and the cut portion and the non-cut portion. Can also be formed intermittently.

As a result, during machining using the cutter 111, while the cutter blade 111a moves according to the relative moving direction of the cut sheet S, half-cuts including free curves, full-cuts, and perforations can be performed on an arbitrary locus. It can be carried out.
