[Basic configuration of sealed letter creation system]
A 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 FIG. 1 and FIG. 2, the sealed letter preparation system 1 according to the present embodiment is printed by a printing device 2 that prints on a envelope paper P <b> 1 with a window and a content paper P <b> 2, and the printing device 2. An envelope sealing device 3 is provided which forms an envelope from the envelope paper P1 with window and stores the content paper P2 printed by the printing device 2 in the envelope to create a sealed letter P3.

  FIG. 3 is a diagram showing an example of a sealed letter P3 created by the sealed letter creating system 1. In this figure, it is shown as a partially expanded view for explanation.

  A window P1a is provided on the envelope paper P1 with a window on which the envelope is formed so that the content paper P2 can be seen.

  The content paper P2 is folded and enclosed in an envelope formed by folding the envelope paper P1 with window. At this time, the address P2a printed on the content paper P2 is sealed so as to be within the window frame of the window portion P1a of the envelope paper P1 with window.

  Further, the inner dimension of the envelope formed by the envelope paper P1 with the window is longer than the outer dimension of the folded content paper P2, so that the user can easily take out the content paper P2 from the created envelope P3. The content paper P2 and the envelope paper P1 with window are folded.

  1 and 2, the printing apparatus 2 is an apparatus that prints and discharges the envelope paper P1 with window and the content paper P2, and the paper feeding unit 111 is provided inside or on the side of the housing that houses each part. I have.

  The paper feed unit 111 includes a first paper feed tray 111a on which an envelope paper P1 with a window is placed, and second paper feed trays 111b to 111d on which content paper P2 having different thicknesses are placed. Yes.

  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 paper P1 with a window placed on the first paper feed tray 111a one by one and transports it 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.

  The printing apparatus 2 includes a printing unit 114 that includes four inkjet heads C, K, M, and Y that eject inks of cyan (C), black (K), magenta (M), and yellow (Y), respectively. doing. A detection unit 118 is provided upstream of the printing unit 114 on the conveyance path 113 and detects the envelope paper P1 with window and the content sheet P2 to be conveyed.

  The printing apparatus 2 also includes a delivery unit 115 that discharges the envelope paper P1 with window and the content paper P2 to the enclosing seal device 3, and a paper discharge that discharges the envelope paper P1 with window and the content paper P2 to the outside of the printing apparatus 2. 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 invert the top and bottom of the content sheet P2.

  As shown in FIGS. 1 and 2, the enclosing / sealing device 3 includes a content folding part 121, an envelope forming part 123, a sealing part 126, and a discharge part 127.

  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, and aligns the aligned content sheets as necessary. This is a mechanism for folding in two, three, or four. The content folding unit 121 is rotatably provided with a main folding roller 131 on the entrance side of the content paper P <b> 2, and cooperates with the main folding roller 131 at a position adjacent to the main folding roller 131. An introduction roller 132 for introducing the content sheet P2 from the conveyance path is rotatably provided. A guide plate 133 is provided below the main folding roller 131 to guide the content sheet P2 introduced by the main folding roller 131 and the introduction roller 132. Further, the guide plate 133 is provided with an abutting member 134 that abuts against the content paper P2 (the front end thereof) and sags the content paper P2 along the guide plate 133 so that the position thereof can be adjusted. An intermediate roller 135 is rotatably provided at a position adjacent to the main folding roller 131 and facing the introduction roller 132. The intermediate roller 135 bends the content paper P2 in cooperation with the main folding roller 131 in a state where the content paper P2 is slackened. The pressing force when folding the content sheet P2 is determined by the pressing force of the intermediate roller 135 against the main folding roller 131. Since the rotation shaft of the intermediate roller 135 is urged in the A1 direction by an urging means 135a such as a spring, the pressing force of the intermediate roller 135 against the main folding roller 131 is determined by the urging force of the urging means 135a. Become. Further, the urging means 135a is provided so that the position can be adjusted along the A1 direction, and the pressing force can be adjusted by adjusting the position of the urging means 135a.

  On the left side of the main folding roller 131 in the drawing, a guide plate 136 for guiding the content sheet P2 bent by the main folding roller 131 and the intermediate roller 135 is provided. The guide plate 136 is provided with an abutting member 137 that abuts against the content paper P2 (the front end thereof) and slackens the content paper P2, so that the position of the abutting member 137 can be adjusted along the guide plate 136. A derivation roller 138 is rotatably provided at a position adjacent to the main fold roller 131 and facing the intermediate roller 135, and the derivation roller 138 sags the content paper P2 in a state where the content paper P2 is slackened. The content sheet P2 is bent and led to the conveyance path in cooperation with the above. The pressing force when folding the content sheet P2 is determined by the pressing force of the lead-out roller 138 against the main folding roller 131. Since the rotation shaft of the derivation roller 138 is urged in the A2 direction by urging means 138a such as a spring, the urging force of the urging means 138a determines the pressing force of the derivation roller 138 against the main folding roller 131. Become. Further, the urging means 138a is provided so that its position can be adjusted along the A2 direction, and the pressing force can be adjusted by adjusting the position of the urging means 138a.

  The envelope forming unit 123 forms the envelope from the printed windowed envelope paper P1 sent from the printing apparatus 2 and stores the content paper P2 in the envelope and is provided at a predetermined position of the windowed envelope paper P1. The envelope is formed by applying water to the re-moistened glue and bending the windowed envelope paper P1 to adhere the facing surfaces at predetermined positions. Specifically, the envelope forming unit 123 encloses the content sheet P2 while wrapping the windowed envelope sheet P1 serving as an envelope. Then, the water application processing unit 124 applies water to the rewet glue portion formed on the envelope paper P1 with the window containing the content paper P2 by the water application unit 124a. A predetermined folding process is performed along the folding line while carrying the envelope paper P1. 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 with window 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. Here, the control unit 119 will be described with reference to an example provided in the printing apparatus 2, but it may be provided in the enclosing / sealing apparatus 3.

  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 control unit 119 controls to select the envelope paper P1 with window and the content paper P2 and feed them from the paper supply unit 111 based on the envelope creation job at the time of printing for envelope creation. The envelope creation job includes setting information for printing and sealing, such as the number of content sheets P2 and the thickness of the content sheet P2, in addition to the print image data. It is transmitted to the printing apparatus 2.

  Further, the control unit 119 controls the printing device 2 and the enclosing sealing device 3 so as to prevent the positional deviation of the content paper P2. Specifically, as shown in FIG. 2, a determination unit 119a, a restoring force strengthening unit 119b, and a storage unit 119c are provided.

  Based on the number of content sheets P2 and the thickness of the content sheet P2 included in the envelope creation job, the determination unit 119a shifts the position of the content sheet P2 enclosed in the envelope formed of the envelope sheet P1 with window. It is determined whether or not this occurs.

  As described above, the content of the envelope formed of the envelope paper P1 with window is longer than the outer size of the folded content paper P2 so that the user can easily take out the content paper P2. The paper P2 and the envelope paper P1 with window are folded. Therefore, when the content paper P2 is displaced in the envelope formed of the envelope paper P1 with window, the address P2a printed on the content paper P2 is removed from the window frame of the window portion P1a of the envelope paper P1 with window. The address P2a may not be visible from the outside of the envelope.

  Whether or not the content sheet P2 is displaced is caused by a restoring force that is a force for the folded content sheet P2 to return to the original shape. That is, the stronger the restoring force of the content paper P2, the greater the pressing force with which the inside of the envelope is pressed, and the greater the frictional force between the content paper P2 and the envelope. For this reason, the positional deviation of the content sheet P2 is unlikely to occur. On the other hand, as the restoring force of the content paper P2 is weaker, the positional deviation of the content paper P2 is more likely to occur. The restoring force of the content paper P2 is determined by the number of content papers P2 and the paper thickness. The restoring force increases as the number of content sheets P2 increases, and the restoring force increases as the sheet thickness increases.

  Therefore, the determination unit 119a has a weak restoring force when the number S of content sheets P2 is smaller than the predetermined number Ts and the sheet thickness D of the content sheets P2 is smaller than the predetermined sheet thickness Td, and the envelope paper P1 with a window It is determined that the content sheet P2 enclosed in the envelope formed in step 3 is displaced.

  The restoring force enhancing unit 119b enhances the restoring force of the content sheet P2 when the determining unit 119a determines that the content sheet P2 enclosed in the envelope formed of the envelope paper P1 with window is displaced. . Specifically, the restoring force strengthening unit 119b adjusts the pressing force by adjusting the position of the urging means 135a and 138a based on a pressing force table to be described later, or thick contents from the second paper feed trays 111b to 111d. The paper is changed to paper P2 and fed.

  The storage unit 119c stores a pressing force table.

  FIG. 4 is a diagram illustrating an example of the pressing force table stored in the storage unit 119c.

  As shown in FIG. 4, pressing forces R1 to R3 corresponding to the number S of content sheets P2 and the sheet thickness D of the content sheets P2 are stored in association with each other. The pressing forces R1 to R3 are pressing forces by the urging means 135a and 138a, and are R1, R2, and R3 from the highest. Therefore, the urging means 135a and 138a can be set in three stages of pressing forces R1 to R3.

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

  In the sealed letter creating system 1, as described above, the restoring force strengthening unit 119b performs the “pressing force adjustment process” in which the pressing force is adjusted by adjusting the position of the urging means 138a in order to strengthen the restoring force, or the second supply One of the “paper change processing” is executed in which the paper trays 111b to 111d are changed to the thick content paper P2 and fed. Therefore, each process will be described below.

<Pressing force adjustment processing>
FIG. 5 is a flowchart showing the processing content of the pressing force adjustment processing of the sealed letter creating system 1 according to the embodiment of the present invention.

  When receiving the envelope creation job (step S101; YES), the control unit 119 acquires information on the number of content sheets P2 and the sheet thickness of the content sheet P2 from the envelope creation job (step S103).

  Then, the control unit 119 adjusts the pressing force by adjusting the positions of the urging means 135a and 138a based on the acquired number of content sheets P2 and the thickness of the content sheet P2 (step S105). Specifically, based on the pressing force table stored in the storage unit 119c, the determination unit 119a has the number of content sheets P2 less than a predetermined number Ts and the sheet thickness D of the content sheet P2 is a predetermined sheet. It is determined whether the thickness is less than Td. Then, when the number S of the content sheets P2 is smaller than the predetermined number Ts and the thickness D of the content sheets P2 is smaller than the predetermined sheet thickness Td, the determination unit 119a has a weak restoring force, and the envelope paper P1 with a window It is determined that the content sheet P2 enclosed in the envelope formed in step 3 is displaced. The determination unit 119a has a strong restoring force when the number S of content sheets P2 is equal to or greater than the predetermined number Ts and / or the sheet thickness D of the content sheets P2 is equal to or greater than the predetermined sheet thickness Td. Therefore, it is determined that there is no displacement in the content paper P2 enclosed in the envelope formed of the envelope paper P1 with window.

  The restoring force strengthening unit 119b extracts the pressing force corresponding to the number S and the sheet thickness D based on the pressing force table, and adjusts the position of the urging means 135a and 138a so as to press with the pressing force. For example, when the determination unit 119a determines that the number S of content sheets P2 is less than a predetermined number Ts and the sheet thickness D of the content sheets P2 is smaller than a predetermined sheet thickness Td, the restoring force strengthening unit 119b displays the pressing force table. Based on this, the pressing force R3 corresponding to the sheet number S smaller than the predetermined sheet thickness Ts and the sheet thickness D thinner than the predetermined sheet thickness Td is extracted, and the positions of the urging means 135a and 138a are adjusted so as to be pressed by the pressing force R3. Do.

  On the other hand, when the determination unit 119a determines that the number S of content sheets P2 is equal to or greater than the predetermined number Ts and / or the sheet thickness D of the content sheets P2 is equal to or greater than the predetermined sheet thickness Td, The restoring force strengthening unit 119b extracts a pressing force R1 and a pressing force R2 that are larger than the pressing force R3 based on the pressing force table, and biases means 135a and 138a so as to press with the extracted pressing force R1 or pressing force R2. Adjust the position of.

  FIG. 6 is a diagram showing the effect of the pressing force adjustment process. (A) has shown the cross section of the sealed letter P3 sealed by the pressing force adjustment process of the sealed letter preparation system 1, and (b) has shown the cross section of the sealed letter sealed by the prior art for comparison. .

  As shown in FIG. 6B, in the prior art, the content sheet P2 is folded with a constant pressing force regardless of the number S of the content sheets P2 and the sheet thickness D of the content sheets P2. Therefore, when the number S of content sheets P2 is smaller than the predetermined number Ts and the sheet thickness D of the content sheets P2 is thinner than the predetermined sheet thickness Td, the restoring force is weak and the content sheet P2 is in the B1-B2 direction. Misalignment occurs.

  On the other hand, as shown in FIG. 6A, in the pressing force adjustment process of the sealed letter creation system 1, the number S of the content sheets P2 is smaller than the predetermined number Ts, and the sheet thickness D of the content sheets P2 is the predetermined sheet. When the thickness is smaller than the thickness Td, the pressing force by the urging means 135a and 138a is adjusted to a pressing force R3 smaller than the pressing forces R1 and R2. For this reason, the restoring force of the content sheet P2 is increased, and the pressing forces C1 and C2 at which the inside of the envelope is pressed are increased. As a result, the frictional force between the content paper P2 and the envelope is increased, so that the positional displacement of the content paper P2 in the B1-B2 direction can be prevented.

  As described above, when the determination unit 119a determines that the content sheet P2 enclosed in the envelope formed of the envelope paper P1 with window is displaced, the restoring force strengthening unit 119b includes the biasing means 135a and 138a. Is adjusted to a pressing force R3 smaller than the pressing forces R1 and R2, so that the restoring force of the content paper P2 can be enhanced. As a result, the pressing force with which the inside of the envelope is pressed increases, and the frictional force between the content paper P2 and the envelope increases, so the content paper enclosed in the envelope formed of the envelope paper P1 with window The position shift of P2 can be prevented. Therefore, the user can surely see the address P2a from the outside of the envelope.

<Paper change processing>
FIG. 7 is a flowchart showing the processing contents of the paper change processing of the sealed letter creating system 1 according to the embodiment of the present invention.

  When receiving the envelope creation job (step S201; YES), the control unit 119 acquires information on the number of content sheets P2 and the thickness of the content sheet P2 from the envelope creation job (step S203).

  The determination unit 119a determines whether or not the number S of content sheets P2 is smaller than the predetermined number Ts (step S205).

  When it is determined that the number S of content sheets P2 is smaller than the predetermined number Ts (step S205; YES), the determination unit 119a determines whether the sheet thickness D of the content sheets P2 is thinner than the predetermined sheet thickness Td. (Step S207).

  When it is determined that the paper thickness D of the content paper P2 is smaller than the predetermined paper thickness Td (step S207; YES), the content paper P2 enclosed in the envelope formed of the envelope paper P1 with a window is weak. It can be inferred that the position shift occurs.

  Therefore, the restoring force enhancing unit 119b changes the sheet thickness (step S209). Specifically, the restoring force strengthening unit 119b selects the content sheet P2 thicker than the sheet thickness of the content sheet P2 acquired from the envelope creation job from any of the second sheet feed trays 111b to 111d, and selects the selected content sheet P2. Paper is fed from the second paper feed tray and printed.

  As described above, when the number S of content sheets P2 is smaller than the predetermined number Ts and the sheet thickness D of the content sheets P2 is smaller than the predetermined sheet thickness Td, the resilience enhancing unit 119b includes the contents included in the envelope creation job. The content paper P2, which is thicker than the paper thickness of the physical paper P2, is fed to the second paper feed trays 111b to 111d.

  Thereby, since the content paper P2 having a thick paper thickness is used, the restoring force of the content paper P2 can be enhanced. For this reason, the pressing force with which the inside of the envelope is pressed increases, and the frictional force between the content paper P2 and the envelope increases, so the content paper P2 enclosed in the envelope formed of the envelope paper P1 with a window. Can be prevented. Therefore, the user can surely see the address P2a from the outside of the envelope.

  As described above, according to the envelope creation system 1 according to the embodiment of the present invention, the determination unit 119a applies the envelope envelope paper P1 with the window based on the number of content sheets P2 and the sheet thickness included in the envelope creation job. When it is determined whether or not a misalignment occurs in the enclosed content paper P2, and the restoring force enhancing unit 119b determines that a misalignment occurs in the content paper P2 enclosed in the envelope paper P1 with a window. The resilience of the content sheet P2 is strengthened.

  As a result, it is possible to prevent the misalignment of the content sheet P2.
