Description

  The present invention relates to a printing apparatus that prevents waste of content sheets without reducing productivity.

  2. Description of the Related Art Conventionally, a sealed letter creating system including a printing apparatus and an encapsulating sealing apparatus is known. In this envelope creation system, the printing apparatus feeds envelope sheets and content sheets from the tray in units of sheets based on an encapsulating seal job, and performs printing on the fed envelope sheets and content sheets.

  The enclosing and sealing device forms an envelope from an envelope paper that has been printed by the printing device, and seals the envelope in a state in which the printed content paper is folded to create a sealed letter.

  Therefore, it is necessary to place the envelope paper and the content paper on the tray of the printing apparatus in an appropriate orientation in advance.

  Patent Document 1 has a tray on which an envelope paper having a placement direction determination unit is placed, a sensor detects the presence or absence of a placement direction determination unit of the envelope paper placed on the tray, and responds to the detection signal. Thus, a technology relating to a paper feeding device for judging whether the envelope paper is properly placed is disclosed.

JP 2015-1224018 A

  However, in the technique of Patent Document 1, since a sensor must be provided for each tray, the manufacturing cost increases as the number of trays increases. Therefore, it is conceivable to detect the envelope sheet conveyed from the tray on the conveyance path and determine the orientation.

  In this case, the order of paper feeding becomes a problem. When the envelope paper is fed after the content paper is fed, the envelope paper can be transported to the sealing position while the printed content paper is folded in the enclosed sealing device. high. However, when the envelope paper is fed after the content paper is fed, the content paper is already conveyed to the enclosing sealing device when it is determined that the orientation of the envelope paper is incorrect using the technique of Patent Document 1. ing. Therefore, the user has to take out the content sheet from the enclosed sealing device. The taken-out content sheet must be discarded, and the content sheet is wasted.

  On the other hand, when the content paper is fed after feeding the envelope paper, if it is determined that the orientation of the envelope paper is wrong using the technique of Patent Document 1, the envelope paper is fed first. Therefore, if the feeding of the content paper is stopped, the waste of the content paper can be prevented. However, if the content paper is fed after the envelope paper is fed, the envelope paper waits at the sealing position while the content paper is folded in the encapsulating device, so the productivity of the encapsulating process is low. Become.

It is not something specific. The technical idea of the present invention can be variously modified within the scope of the claims.

[Basic configuration of sealed letter creation system]
First, the basic configuration of the sealed letter creation system 1 according to the embodiment of the present invention will be described. FIG. 1 is a schematic configuration diagram showing a configuration of a sealed letter creating system 1 according to an embodiment of the present invention, and FIG. 2 is a functional configuration diagram schematically showing the sealed letter creating system according to the embodiment.

  As shown in FIGS. 1 and 2, a sealed letter creating system 1 according to the present embodiment includes a printing device 2 and an encapsulating and sealing device 3.

  The printing device 2 is a device that prints on the envelope paper P1 and the content paper P2 and discharges it. A plurality of types of paper (sheet-like content paper that becomes the content) is provided inside or on the side of the housing that houses each part. A paper feed unit 111 capable of storing P2 and envelope paper P1) is provided.

  The paper feed unit 111 includes a first paper feed tray 111a on which envelope paper P1 is placed, and second paper feed trays 111b to 111d on which content paper P2 having different sizes is placed.

  A conveyance path 113 is connected to each of the sheet feeding sections 111, and a conveyance section 112 composed of conveyance rollers or the like is provided at a plurality of locations on the conveyance path 113. The transport unit 112 takes out the envelope sheets P1 placed on the first paper feed tray 111a one by one and transports them on the transport path 113. Similarly, the transport unit 112 takes out the content sheets P2 placed on the second paper feed trays 111b to 111d one by one and transports them on the transport path 113.

  In addition, the printing apparatus 2 includes a printing unit 114 including four inkjet heads C, K, M, and Y that respectively eject inks of cyan (C), black (K), magenta (M), and yellow (Y). have. A detection unit 118 is provided upstream of the printing unit 114 on the conveyance path 113.

  FIG. 3 is an explanatory diagram showing the relationship between the detection unit 118 and the envelope paper P1 transported on the transport path 113. FIG. 3A is a diagram illustrating a conveyance state when the orientation of the envelope paper P1 is normal, and FIGS. 3B and 3C are cases where the orientation of the envelope paper P1 is abnormal. It is the figure which showed the conveyance state. That is, when the envelope paper P1 is in the paper orientation (front and back, front and back) shown in FIG. 3A, an envelope can be appropriately created, but the envelope paper P1 is shown in FIG. 3B and FIG. 3C. If the paper orientation is correct, the sealed letter cannot be created properly.

  As shown in FIG. 3A, the detection unit 118 is a scanner (CIS: Contact Image Sensor: illustrated) in which a plurality of imaging elements are arranged in a direction (X1-X2 direction) orthogonal to the conveyance direction of the envelope paper P1. The presence / absence and shape of the paper orientation determination portion provided on the envelope paper P1 is detected by the output of the scanner.

  The envelope paper P1 has a flap portion P1a which is a paper orientation discrimination portion, and the flap portion P1a is asymmetric in a direction (X1-X2 direction) perpendicular to the transport direction with respect to a center line S parallel to the transport direction. It has a different shape. Specifically, the inclination angle θ1 of the flap part P1a with respect to the conveying direction of the inclined part P1b is larger than the inclination angle θ2 of the flap part P1a with respect to the conveying direction of the inclined part P1c.

  Therefore, as shown in FIG. 3A, when the paper orientation of the envelope paper P1 is normal, the flap portion P1a is the head in the transport direction, and the transport direction in the direction orthogonal to the transport direction (X1-X2 direction) The distance from a predetermined reference line R parallel to the tip P1d of the flap portion P1a is L1.

  Therefore, based on the output of the scanner of the detection unit 118, when the distance from the reference line R to the front end P1d of the flap portion P1a is L1, it can be determined that the paper orientation of the envelope paper P1 is normal.

  On the other hand, as shown in FIG. 3B, when the paper orientation of the envelope paper P1 is opposite to the left-right direction (X1-X2 direction) with respect to FIG. 3A, the left-right direction (X1-X2 direction). ), The distance from the reference line R to the tip P1e of the flap portion P1a is L2.

  Therefore, based on the output of the scanner of the detection unit 118, when the distance from the reference line R to the tip P1e of the flap part P1a is L2, it can be determined that the paper orientation of the envelope paper P1 is abnormal.

  Further, as shown in FIG. 3C, when the paper orientation of the envelope paper P1 is opposite to the transport direction (Y2 direction) with respect to FIG. Become. At this time, the distance from the reference line R to the leading edge P1f of the envelope paper P1 in the left-right direction (X1-X2 direction) is L3.

  Therefore, based on the output of the scanner of the detection unit 118, when the distance from the reference line R to the leading edge P1f of the envelope paper P1 is L3, it can be determined that the paper orientation of the envelope paper P1 is abnormal.

  Returning to FIGS. 1 and 2, the printing apparatus 2 includes a delivery unit 115 that discharges the envelope paper P <b> 1 and the content paper P <b> 2 to the sealed sealing apparatus 3, and a discharge that discharges the envelope paper P <b> 1 and the content paper P <b> 2 out of the printing apparatus 2. A paper unit 116 and a reversing unit 117 that reverses the content sheet P2 that has been transported through the transport path 113 and returns it to the transport path 113 to reverse the top and bottom of the content sheet P2 are provided.

  The enclosing and sealing device 3 forms an envelope from the envelope paper printed by the printing device 2, and stores the content paper printed by the printing device 2 in the envelope to create a sealed letter. As shown in FIGS. 1 and 2, the sealed sealing device 3 includes a content folding part 121, an envelope forming part 123, a sealed part 126, and a discharge part 127.

  The content folding unit 121 accumulates and aligns printed content sheets P2 sent from the printing apparatus 2 for each number of envelope sheets, and aligns the aligned content sheets as necessary. A folding mechanism. The content folding unit 121 is configured to be capable of a plurality of folding processes such as bi-folding and tri-folding.

  The envelope forming unit 123 forms the envelope from the printed envelope paper P1 sent from the printing apparatus 2, stores the content paper P2 in the envelope, and rehumidifies the envelope paper P1 provided at a predetermined position. Water is applied to the glue, and the envelope is formed by adhering the facing surfaces at predetermined positions while bending the envelope paper P1. Specifically, the envelope forming unit 123 encloses the content paper P2 while conveying the envelope paper P1 serving as an envelope, and forms the envelope paper P1 containing the content paper P2 in the water application processing unit 124. Water is applied to the re-wet glue part that has been applied by the water application part 124a, and the paper folding part 125 performs a predetermined folding process along the fold line while transporting the envelope paper P1 after the water application. Note that a folding part 122 is connected to the envelope forming part 123, and this folding part 122 is a mechanism used for a four-fold envelope (that is, when the envelope paper P1 is folded three times). When the envelope is a three-fold envelope, the folding part 122 is not used, and the envelope forming part 123 performs folding and sealing at the same time.

  The sealing unit 126 seals the envelope formed by the envelope forming unit 123 and containing the content paper P2 to complete the sealed letter. In the sealing part 126, it can also seal by pressure-bonding the pressure sensitive adhesives of an envelope. The discharge unit 127 lifts and conveys the sealed letter to the outside of the apparatus housing, and then horizontally discharges and conveys the sealed letter to the discharge tray 127a.

  The printing apparatus 2 of the sealed letter creating system 1 includes a control unit 119 that performs overall control of each part of the sealed letter creating system 1.

  The control unit 119 controls the overall operation of the printing apparatus 2 and the overall operation of the enclosing / sealing apparatus 3. The control unit 119 includes a CPU, RAM, ROM, hard disk, and the like. An operation panel 120 is connected to the control unit 119.

  The operation panel 120 includes a display / input panel (not shown), a start key for starting reading and printing, a stop key for stopping reading and printing, a numeric keypad for inputting the number of prints, etc. And an operation signal based on a user operation is supplied to the control unit 119.

  The display / input panel of the operation panel 120 includes a pressure-sensitive or electrostatic transparent touch panel disposed on the front surface and a liquid crystal display panel disposed on the back surface of the touch panel for displaying various display screens (none of which are shown). ). The user can press the confirmation button displayed on the display screen by directly touching the surface of the touch panel with a finger while watching the message displayed on the LCD panel such as “Reset message”. Can do.

  The control unit 119 performs control to select and feed the envelope paper P1 and the content paper P2 from the paper feeding unit 111 based on the sealed sealing job during printing for creating a sealed letter. The sealed sealing job includes print image data and setting information for sealed sealing, and is transmitted from the external terminal device to the printing apparatus 2 at the time of sealed letter creation printing. The enclosing sealing job designates the type of envelope paper, the size of the content paper, and the number of content papers for creating one sealed letter.

  Furthermore, the control unit 119 controls the printing apparatus 2 so as to prevent waste of the content paper P2 without reducing productivity. Specifically, as shown in FIG. 2, a determination unit 119a and a conveyance control unit 119b are provided.

  The determination unit 119a determines the correctness of the orientation of the envelope paper P1 based on the detection result by the detection unit 118. Specifically, as described above, based on the output of the scanner of the detection unit 118, the determination unit 119a determines that the distance from the reference line R to the tip P1d of the flap portion P1a is L1, and envelope paper P1. Is determined to be normal.

  On the other hand, the determination unit 119a determines whether the distance from the reference line R to the leading end P1e of the flap portion P1a is L2 or from the reference line R to the leading end P1f of the envelope paper P1 based on the output of the scanner of the detecting unit 118. Is L3, it is determined that the paper orientation of the envelope paper P1 is abnormal.

  When the envelope paper P1 is newly placed on the first paper feed tray 111a, the transport control unit 119b feeds the first envelope paper P1 from the first paper feed tray 111a based on the sealed sealing job. . Here, the first paper feed tray 111a is provided with a paper presence sensor (not shown). When the envelope paper P1 is reset due to a paper orientation error described later, the paper presence sensor is temporarily switched from on to off. Then, it is determined that the envelope paper P1 is newly placed on the first paper feed tray 111a by switching on.

  When the determination unit 119a determines that the orientation of the envelope paper P1 fed from the first paper feed tray 111a is normal, the transport control unit 119b stores the envelope paper P1 determined to be normal. The first content sheet P2 to be fed is fed from the second paper feed trays 111b to 111d. As a result, the first envelope can be created by combining the first envelope paper P1 and the first content paper P2 that are in the normal paper orientation (front and back and front and back).

  As described above, when the envelope paper P1 is newly placed on the first paper feed tray 111a, the transport control unit 119b performs the first envelope paper P1 from the first paper feed tray 111a based on the sealed sealing job. 1 is to be stored in the envelope paper P1 determined to be normal when the determination unit 119a determines that the orientation of the envelope paper P1 fed from the first paper feed tray 111a is normal. Since the content paper P2 of the eyes is fed from the second paper feed trays 111b to 111d, the content paper P2 is fed only when the paper orientation of the envelope paper P1 is normal. As a result, it is possible to prevent the content paper P2 previously fed from staying in the enclosing sealing device 3, so that waste of the content paper P2 can be prevented.

  On the other hand, if the control is always performed so that the content paper P2 is fed after the envelope paper P1 is fed, productivity decreases.

  As described above, in the enclosed sealing device 3, the content folding unit 121 accumulates and aligns the printed content sheets P2 sent from the printing apparatus 2 for each number of envelope sheets, Fold the aligned content sheets as needed. The envelope forming unit 123 stores the content paper P2 in the envelope while forming an envelope from the printed envelope paper P1 sent from the printing apparatus 2.

  At this time, if the envelope paper P1 is fed and then the content paper P2 is controlled to be fed, the envelope paper P1 first reaches the envelope forming section 123, and the content folding section 121 is the content paper. While P2 is accumulated, aligned, and folded, the envelope paper P1 is waiting at the envelope forming unit 123. Thus, if the control for feeding the content paper P2 is continued after the envelope paper P1 is fed, the decrease in productivity becomes remarkable.

  Therefore, the transport controller 119b transports the envelope paper P1 from the first paper feed tray 111a after feeding the content paper P2 from the second paper feed trays 111b to 111d after the next pass. The unit 112 is controlled.

  If the orientation of the first envelope paper P1 is normal, it is very likely that the orientation of the second and subsequent envelope papers P1 is also normal. Therefore, productivity can be improved by feeding the envelope paper P1 after feeding the content paper P2. Specifically, since the envelope paper P1 is conveyed to the envelope forming unit 123 while the content folding unit 121 collects, aligns, and folds the content paper P2, it prevents a decrease in productivity. Can do.

  In addition, when the determination unit 119a determines that the orientation of the envelope paper P1 is abnormal, the conveyance control unit 119b causes the conveyance unit 112 to discharge the envelope paper P1 determined to be abnormal to the paper discharge unit 116. Control.

  As a result, the user can restart the sealed sealing process immediately by re-loading the envelope paper P1 placed on the first paper feed tray 111a in the normal direction. Further, when the determination unit 119a determines that the orientation of the envelope paper P1 is abnormal, the content paper P2 is not fed, and therefore the content paper P2 can be prevented from being wasted.

[Action]
Next, the operation of the sealed letter creation system 1 according to the embodiment of the present invention will be described.

  FIG. 4 is a flowchart showing the operation of the sealed letter creating system 1 according to the embodiment of the present invention.

  As shown in FIG. 4, when the control unit 119 receives a sealed sealing job from an external terminal device (step S101; YES), the transport control unit 119b newly adds envelope paper to the first paper feed tray 111a. It is determined whether or not P1 is placed (step S103).

  When it is determined that the envelope paper P1 is newly placed on the first paper feed tray 111a (step S103; YES), the transport control unit 119b performs the first mail from the first paper feed tray 111a based on the sealed sealing job. Envelope paper P1 is fed (step S105).

  Then, the determination unit 119a determines whether or not the first envelope paper P1 fed from the first paper feed tray 111a is normal (step S107).

  When it is determined that the orientation of the first envelope paper P1 is abnormal (step S107; NO), the first envelope paper P1 needs to be discharged out of the printing apparatus 2.

  Therefore, the control unit 119 stops printing (step S109), and the conveyance control unit 119b controls the conveyance unit 112 to discharge the envelope paper P1 determined to be abnormal to the paper discharge unit 116 (step S109). S111).

  Then, the control unit 119 displays, on the operation panel 120, a “paper orientation error” indicating that the first paper orientation of the envelope paper P1 is abnormal, and a “reset message” prompting the user to reset the envelope paper P1. Is displayed (step S113).

  When the confirmation button is pressed down on the operation panel 120 by a user operation (step S115; YES), the control unit 119 shifts the process to step S103.

  On the other hand, when it is determined that the paper orientation of the envelope paper P1 is normal (step S107; YES), the transport control unit 119b first stores the content paper P2 to be stored in the envelope paper P1 determined to be normal. Are fed from the second paper feed trays 111b to 111d (step S117).

  Next, the conveyance control unit 119b feeds the envelope paper P1 from the first paper feed tray 111a after feeding the content paper P2 from the second paper feed trays 111b to 111d for the next pass (step S119). ).

  Then, the determination unit 119a determines whether or not the orientation of the envelope paper P1 fed from the first paper feed tray 111a is normal (step S121).

  When it is determined that the orientation of the envelope paper P1 is abnormal (step S121; NO), the envelope paper P1 is discharged out of the printing device 2 and the content paper P2 remaining in the sealed sealing device 3 is removed. It is necessary to discharge. The envelope paper P1 may be discharged from the paper discharge unit 116. However, since a plurality of the content paper P2 are folded and difficult to carry, it is better for the user to remove them.

  Therefore, the control unit 119 stops printing (step S123), and the conveyance control unit 119b controls the conveyance unit 112 to discharge the envelope paper P1 determined to be abnormal to the paper discharge unit 116 ( In step S125, the operation panel 120 displays a “paper orientation error” indicating that the envelope paper P1 has an abnormal paper orientation and a “content removal message” prompting the removal of the content paper P2 (step S127). ).

  Then, when the removal of the content sheet P2 is detected (step S129; YES), and the user presses the confirmation button on the operation panel 120 (step S115; YES), the control unit 119 performs step S103. Transfer processing to.

  On the other hand, when it is determined that the paper orientation of the envelope paper P1 is normal (step S121; YES), the control unit 119 continues the processing of steps S103 to S133 until the job ends (step S133).

  As described above, according to the present embodiment, the determination unit 119a determines the correctness of the envelope paper P1 based on the detection result by the detection unit 118, and the conveyance control unit 119b determines the first paper feed tray 111a. When the envelope paper P1 is newly loaded, the first envelope paper P1 is fed from the first paper feed tray 111a based on the job, and the determination unit 119a determines that the paper orientation of the envelope paper P1 is normal. When it is determined, the first content sheet P2 to be stored in the envelope sheet P1 determined to be normal is fed from the second sheet feed trays 111b to 111d, and the second sheet and subsequent sheets are fed from the second sheet feed tray. After the content sheet is fed from the sheet feeding unit 112, the conveying unit 112 is controlled to feed the envelope sheet P1 from the first sheet feeding tray 111a.

  Therefore, the content paper P2 is fed only when the paper orientation of the envelope paper P1 is normal. As a result, it is possible to prevent the content paper P2 previously fed from staying in the enclosing sealing device 3, so that waste of the content paper P2 can be prevented. Further, since the envelope sheet P1 is fed after the contents sheet is fed after the next sheet, it is possible to prevent a decrease in productivity.

  Further, when the determination unit 119a determines that the orientation of the envelope paper P1 is abnormal, the conveyance control unit 119b causes the conveyance unit 112 to discharge the envelope paper P1 determined to be abnormal to the outside of the printing apparatus 2. Control.

  As a result, the user can restart the sealed sealing process immediately by re-loading the envelope paper P1 placed on the first paper feed tray 111a in the normal direction. Further, when the determination unit 119a determines that the orientation of the envelope paper P1 is abnormal, the content paper P2 is not fed, and therefore the content paper P2 can be prevented from being wasted.

  In the present embodiment, the control unit 119 is provided in the printing apparatus 2. However, the present invention is not limited to this, and the control unit 119 may be provided in the enclosing sealing device 3.
