And “first fold roller 45”, the “fold 1” is formed.

  On the other hand, the printed content 7 waiting in the content standby unit 60 is moved along the content supply transport path NIR by the first and second content transport roller pairs 62 and 63 and the main fold roller 42 and the second fold roller 42. The “fold 1” is formed by the one sub-folding roller 45 and enclosed.

  At the stage where the printed contents 7 are enclosed in the “fold 1”, the surface side of the envelope lower paper piece 4 (FIGS. 1 and 2) of the envelope paper 1 is the water application rotating body in the water application unit 70. 75 is folded so as to be opposed to 75 to form “Fold 1”. After that, the envelope sheet 1 is folded with the main fold roller 42 starting from the folded envelope lower paper piece 4 (FIGS. 1 and 2). The leading portion of the envelope lower paper piece 4 (FIGS. 1 and 2) which is conveyed and taken along the folding conveyance path FTR by the one subfolding roller 45 while taking the forward path as shown in “d”. Is detected by the paper detection sensor 46, the drive start timing to the third motor 74 is controlled via the control unit 100 for the water application rotator 75 waiting at the initial position. 75 starts rotating in the same direction as the forward conveyance direction of the envelope paper 1 That.

  At this time, as shown in FIGS. 8 (a) and 8 (b), the envelope paper 1 in which the envelope upper paper piece 2, the envelope middle paper piece 3 and the envelope lower paper piece 4 are connected to each other is formed under the envelope by, for example, Form 1 and Form 2. While the position of the re-wet paste 8 adhered to a predetermined adhesion position on the surface of the paper piece 4 is different from the transport direction of the envelope paper 1, the re-wet paste 8 with respect to the width direction orthogonal to the transport direction. The form 1 and form 2 are divided into left and right at the same position.

  That is, in the form 1, the re-wet paste 8 is attached at the position of the dimension X1 close to the folding line 5B, and in the form 2, the length in the transport direction of the envelope upper paper piece 2 is shorter than that of the form 1, so that the re-wet paste 8 Is attached to the position of the dimension X2 away from the folding line 5B.

  Accordingly, the position information of the predetermined bonding position (re-moistening paste 8) with respect to the conveyance direction of the envelope paper 1 by the forms 1 and 2 is the form provided on the operation panel unit 21 in the printing machine 20 (FIG. 3). When the form type of the envelope paper 1 is input from an information input key (not shown), the control unit 25 in the printing machine 20 (FIG. 3) and the control unit 100 in the sealing and sealing machine 30 (FIG. 3) are operated. 3 is transmitted to the storage unit 110 (FIG. 3) and read from the storage unit 110, and based on this position information, the rotation of the water application rotator 75 is started via the third motor 74 in the water application unit 70. The timing is controlled.

On the other hand, since either one of the cases where the water 72 is applied twice is selectively performed, the usability of the water application unit 70 is improved.

  At this time, the number of times of water application to the re-wetting paste 8 can be set in advance according to the type of form of the envelope paper 1 and stored in the storage unit 110, and the stored water application times can be performed.

  That is, as shown in FIGS. 9A to 9C, the water 72 is once applied to the re-wet paste 8 adhered to a predetermined adhesion position on the surface of the envelope lower paper piece 4 of the envelope paper 1. In the case of coating, “fold 1” is formed by the main folding roller 42 and the first sub-folding roller 45 in the envelope sheet folding and content enclosing unit 40 (FIG. 5). After the leading portion of the folded envelope lower paper piece 4 is detected by the paper detection sensor 46, the water-coating rotating body 75 is rotated forward via the third motor 74 in the same direction as the forward conveyance direction of the envelope paper 1 at a predetermined timing. Then, the second blade 76 planted on the outer peripheral surface 75a of the water-coating rotating body 75 is brought into contact with the re-moistening paste 8 adhered to a predetermined adhesion position on the surface of the envelope lower paper piece 4 so as to contact the second blade 76. Since the replenished water 72 is once applied to the re-wet paste 8, the envelope paper 1 Without pause, flexibility can be water coating along the re Shimenori 8 in the second blade 76 having a.

  Accordingly, in the process of folding the envelope sheet 1 by the envelope sheet folding unit / content enclosing unit 40, the re-wet paste 8 adhered to the envelope sheet 1 without being stopped during the forward transfer. Can be watered, thus contributing to an increase in sealing processing speed.

  At this time, the normal rotation start timing of the water coating rotary member 75 is controlled based on the positional information of the re-wetting paste 8 with respect to the transport direction of the envelope paper 1 stored in the storage unit 110 in the sealing device 30 (FIG. 3). By controlling via the part 100, it is possible to make contact with only the re-wet paste 8 having the second blade 76 adhered to a predetermined bonding position in a timely manner.

  Returning to FIG. 5, after that, the leading portion of the envelope lower paper piece 4 folded in the envelope paper 1 abuts into a bent piece 47 a provided at one end of the second abutting sheet metal 47. In order to be further fed by the folding roller 42 and the first auxiliary folding roller 45, the leading portion of the envelope lower paper piece 4 is in contact with the bent piece 47 a of the second abutting sheet metal 47, along the inside of the second abutting sheet metal 47. If the locus indicated by “e” is taken and the envelope paper 1 is further fed, a bulge as indicated by “He” occurs in the middle of the envelope paper 1, and this bulge portion is connected to the main fold roller 42 and the second fold roller 42. By being sucked in between the subfolder roller 48 and passing between the main fold roller 42 and the second subfolder roller 48, a “fold 2” is formed, so that the envelope upper paper piece 2 of the envelope sheet 1 is formed. The back of the paper faces the surface of the envelope envelope 4 Envelope 9 is formed is folded into an envelope shape.

  When the envelope sheet 1 on which “fold 2” is formed is conveyed by the main folding roller 42 and the second subfolding roller 48, the conveyance direction of the envelope sheet 1 is set in the backward conveyance direction opposite to the forward conveyance direction. In order to change the direction, the envelope lower sheet piece 4 folded together with the envelope paper 1 is also directed in the backward conveyance direction. However, in the backward conveyance operation of the envelope paper 1, the envelope paper 1 is planted on the outer peripheral surface 75 a of the water-coated rotating body 75. Regardless of whether or not the second blade 76 contacts the re-wetting paste 8 on the envelope lower paper piece 4, the flexible second blade 76 does not interfere with the return path conveying operation of the envelope sheet 1. .

  Furthermore, after the envelope 9 is sealed by folding it into an envelope shape, this envelope 9 is sent to the crimping portion 80, and as shown in FIG. The adhesives 6 are pressed together, and the back surface of the envelope upper paper piece 2 of the envelope paper 1 is securely bonded to the surface of the envelope lower paper piece 4 and automatically sealed along with the pressure bonding operation.

  Thereafter, the completed envelope 9 is discharged to the paper discharge unit 95 by the sealing device 90 (70, 80).

  On the other hand, since the water 72 is less likely to adhere when the room temperature is low depending on the type of the re-wetting paste 8, in this case, as shown in FIGS. 10 (a) to 10 (c), the envelope lower sheet piece 4 of the envelope sheet 1 is used. Water 72 is applied twice to the re-wet paste 8 adhered to a predetermined bonding position on the surface of the film.

  In the case of this two-time coating, the first water-coating is performed by rotating the water-coating rotator 75 forward via the third motor 74 in the same direction as the forward conveyance direction of the envelope paper 1 as in the case of FIG. Then, the second blade 76 planted on the outer peripheral surface 75a of the water-coating rotating body 75 is brought into contact with the re-wet paste 8 adhered to a predetermined adhesion position on the surface of the envelope lower paper piece 4 for the first time. After coating, when the leading portion of the folded envelope lower paper piece 4 abuts against the second abutting sheet metal 47 and the conveyance direction is reversed to return to the backward conveyance direction, The water application rotator 75 is reversed in the same direction via the third motor 74, and the second blade 76 planted on the outer peripheral surface 75 a of the water application rotator 75 is adhered to the surface of the envelope lower paper piece 4 with a predetermined adhesion. The second coating is done by touching the re-wet paste 8 attached to the position. , Without stopping the envelope sheet 1 temporarily in the second blade 76 having flexibility back and forth along the re Shimenori 8 can be water fill.

  Accordingly, in the case of the two-time coating, as in the case of the one-time coating, the envelope paper 1 is stopped during the reciprocating conveyance in the process of folding the envelope paper 1 by the envelope paper folding and content enclosing unit 40. Since it can be wetted with respect to the re-wet paste 8 stuck on the envelope paper 1 without making it, it can contribute to the improvement of the sealing processing speed.

  The subsequent crimping and paper discharge operations on the envelope paper 1 are the same as in the case of one-time coating, and therefore description thereof is omitted.

  Accordingly, since the rotation direction of the water application rotating body 75 when the water 72 is applied to the rehumidifying paste 8 by the second blade 76 is set to the same direction as the conveying direction of the envelope paper 1, Water can be satisfactorily applied to the glue 8 with the second blade 76.

  Therefore, according to the water application unit 70 according to the present invention, the envelope paper 1 that has been printed is folded into an envelope shape, and the re-humidified paste 8 that is adhered to a predetermined adhesion position on the envelope paper 1 is automatically sealed. When the controller 100 rotates the water-coating rotating body 75 in the same direction as the transport direction of the envelope paper 1 via the third motor 74 and the envelope paper 1 is transported at least in the forward transport direction. Along with the rotation operation of the water-coating rotator 75, the blade 76 implanted on the outer peripheral surface 75a of the water-coating rotator 75 is brought into contact with a predetermined bonding position, and water 72 replenished to the blade 76 is applied to the re-wet paste Therefore, the water 72 can be applied only to the re-wetting paste 8 that is aimed at least when the envelope paper 1 is being conveyed in the forward conveyance direction, so that a large amount of envelopes 9 such as various documents and direct mails can be applied. Can be sealed Both can be miniaturized water application portion 70 to not apply a large pressure over the entire width of the envelope 9.

  In the embodiment described in detail above, the example in which the re-moistening paste 8 is applied in advance to a predetermined adhesion position on the surface of the envelope lower paper piece 4 of the envelope paper 1 and the water 72 is applied by the water application unit 70 has been described. However, the present invention is not limited to this, and when the re-wetting paste 8 is not attached to the predetermined adhesion position on the envelope paper 1, the illustration is omitted here, but the paste is accommodated in the container as a sealing device, and A rotating body is installed in the vicinity of the container, glue is replenished from the container with a blade planted on the outer peripheral surface of the rotating body, and the blade is placed at a predetermined adhesion position on the envelope paper 1 folded into an envelope shape. Even in this case, since the rotation direction of the rotating body may be set in the same direction as the conveyance direction of the envelope paper 1, the envelope paper to which no re-wetting paste is attached Can be automatically sealed, and the envelope paper folding part can also be used In the course of the folding operation to the envelope sheet by enclosure, it is possible to glue the predetermined bonding position on the envelope sheet without stopping the envelope sheet, can contribute to improvement of sealing processing speed.

  Therefore, the rotating body (75) applies the water 72 to the re-wet paste 8 attached to the predetermined adhesion position on the envelope paper 1 through the blade (76) implanted on the outer peripheral surface, or Alternatively, since the paste is applied to a predetermined bonding position on the envelope paper 1, the rotating body (75) gives an adhesive function to the predetermined bonding position on the envelope paper 1.
