  FIG. 4 is a side view of the cutting unit 9 of the present embodiment, and FIG. 5 is a cross-sectional view illustrating a configuration example of a cut position control mechanism in the cutting unit 9 of the present embodiment. 5 is a cross-sectional view taken along line S2-S2 in FIG. FIG. 6 is a cross-sectional view for explaining the operation of the cut position control mechanism in the cutting portion 9.

  One of the fixed shafts 50 is fixed to the device housing 41 and the other is fixed to the device housing (not shown). A slitter knife 51 (first slitter knife) is rotated by a bearing 52 and a knife fixing plate 53. It is supported freely.

  The slitter knife 51 is always biased in the direction of arrow (c) by a compression spring 55 (biasing means) fixed at one end to the fixed shaft 50 by a stopper 54, and the other slitter knife 67 (second slitter knife). ) In contact with the side surface of the outer peripheral portion.

  As shown in FIG. 4, the slitter knife 51 and the slitter knife 67 are overlapped at the outer periphery, and the sheet 18 (Z-fold pressure-bonded postcard 18Z) is formed between the slitter knife 51 and the slitter knife 67 in the paper transport direction (A). ) Passes, the sheet 18 is cut.

The apparatus housing 41 is provided with a pulse motor 57, and a worm 58 is mounted and fixed on its output shaft.
One end of the rotary shaft 59 is rotatably attached to a bearing 60 fixed to the apparatus housing 41, and a worm gear 61 is fixed at a position facing the worm 58. That is, the rotation shaft 59 is driven by the rotation of the pulse motor 57.

The other end of the rotary shaft 59 is also pivotally supported by a device housing (not shown). Further, a worm 62 is mounted and fixed on the rotary shaft 59.
A cutter frame 64 is fixed to the cutter base 63 fixed to the apparatus housing 41.

  The cutter frame 64 has a U-shape with opposing support wall surfaces 64a. A fixed shaft 65 is provided in parallel to the fixed shaft 50 so as to penetrate the support wall surface 64a. Is fixed to the cutter frame 64 by a stopper 66.

A slitter knife 67 is pivotally supported on the fixed shaft 65 by a bearing 68 and a knife fixing plate 69.
A U-shaped cutter holder 70 is provided at a position in contact with the inner ring at both ends of the bearing 68, and a worm rack 71 is fixed to the lower side of the cutter holder 70 so as to face the worm 62.

  As a result, the slitter knife 67 passes through the worm 62, the worm rack 71, and the cutter holder 70 by a predetermined distance in the left or right direction in FIG. Displace.

  In FIG. 6, the slitter knife 51 and the slitter knife 67 indicated by the two-dot chain line are located at the cutting width W1 (in this case, 148.5 mm) from the paper edge reference position W0 and at the above-described home position. Indicates.

  In order to move the slitter knife 67 by a distance αe equivalent to the positional displacement amount α of the sheet 18 described above, the cutting controller 80 rotates the pulse motor 57 by the calculated number of rotations. Then, the worm 62 rotates together with the rotating shaft 59, and the worm rack 71 is moved in the direction of the arrow (D) by a predetermined distance αe.

The cutter holder 70 integrated with the worm rack 71 is also moved by the distance αe, and the slitter knife 67 is also moved in the direction of the arrow (v).
The cutter holder 70 is in contact with the bearing 68 to which the slitter knife 67 is attached. However, since the cutter holder 70 is in contact only with the inner ring, the rotation operation of the slitter knife 67 is not hindered.

  The other slitter knife 51 is in contact with the slitter knife 67 at the tip of the tooth, and is moved by the distance αe following the compression spring 55 simultaneously with the movement of the slitter knife 67.

Is done.

  Thus, by urging the slitter knife 51 to follow the slitter knife 67 by the compression spring 55, the pulse motor 57, the worm 58, the worm gear 61, and the worm 62 for controlling displacement only on the slitter knife 67 side. The worm rack 71 and the like need only be provided, and the configuration is simplified.

Hereinafter, the operation of the pressure-bonded printed material creating apparatus 1 of the present embodiment will be described.
In this case, as an example, a case where the Z-fold pressure-bonded postcard 18Z is created from the tri-fold sheet 18 will be described as an example.
That is, for example, as illustrated in FIG. 2A, an example in which one Z-fold pressure-bonded postcard 18Z is cut out from one sheet 18 made of plain paper having a sheet length L and a sheet width W or the like. Indicates.

  In the sheet 18 provided to the pressure-bonded printed matter creating apparatus 1 according to the present embodiment, the confidential information description surface A, the confidential information description surface B, and the destination description surface C are arranged on the front side, and the public information description is provided on the rear side. Surface D, confidential information description surface E, and confidential information description surface F are arranged.

The confidential information description surface A, the confidential information description surface B, the confidential information description surface E, and the confidential information description surface F of the sheet 18 are preprinted with confidential information that should not be read by others during delivery.
On the destination description surface C, information such as the address of the delivery destination of the Z-fold crimping postcard 18Z, which does not require confidential management, is printed.

On the public information description surface D, information such as a sender, which does not require confidential management, is printed.
The confidential information description surface A and the public information description surface D, the confidential information description surface B and the confidential information description surface E, and the destination description surface C and the confidential information description surface F are in positions that are mutually opposite.

  For example, plain paper having a sheet width W and a sheet length L is used as the sheet 18, and the cutting width W1 matches the postal standard from one sheet 18 by the arrangement as illustrated in FIG. One Z-fold crimped postcard 18Z of 5 mm is prepared.

  As illustrated in FIG. 8 described above, for example, when the sheet 18 is A4 paper, the sheet length L is 297 mm, the sheet width W is 210 mm, and the sheet length L is set at the positions of the folding line 18b and the folding line 18a. The sheet is folded in three and crimped, and the sheet width W side is cut by a cutting line 18c at the position of the cutting width W1 to form a Z-fold crimped postcard 18Z.

  In this case, as an example, the folding width L1 of the confidential information description surface A is 101 mm, the folding width L2 of the confidential information description surface B is 101 mm, and the folding width L3 of the destination description surface C is 95 mm.

  Then, as illustrated in FIG. 2B, after the powder adhesive 17 is applied to the secret information description surface A and the secret information description surface F by the first folding of the sheet 18 at the fold line 18b, FIG. As illustrated in c), it is folded in three and crimped so that the secret information description surface A and the secret information description surface B face each other, and crimped so that the secret information description surface F and the secret information description surface E face each other. Further, by cutting off the surplus end portion at the cutting line 18c, the Z-fold pressure-bonded postcard 18Z is obtained.

The process for creating the sheet 18 (Z-fold pressure-bonded postcard 18Z) as shown in FIG. 2 is performed as follows in the pressure-bonded printed material creating apparatus 1 of the present embodiment.
The sheet 18 supplied from the sheet feeding unit 2 is fed into the adhesive application unit 5 after being temporarily folded in the temporary folding unit 4 such as the pre-folding as illustrated in FIG.

  In the adhesive application unit 5, the powder adhesive 17 is applied to the secret information description surface F and the secret information description surface A of the pre-folded sheet 18.

  After the sheet 18 coated with the powder adhesive 17 reaches the temporary / main fixing unit 6 and passes between the pressure roller 27 and the pressure roller 28, the powder adhesive 17 is put on the assumption. As shown in FIG. 2C, the main folding unit 7 is folded in three so that the application surface of the powder adhesive 17 is opposed to the lower endless heat belt 26 of the temporary / main fixing unit 6 again. Crimping is performed by passing between the upper endless heat belts 29.

  Thereafter, by passing through the line sensor 40, a positional deviation amount α, which is a deviation amount of the cutting line 18c of the Z-fold crimping postcard 18Z from the paper end reference position W0, is measured and input to the cutting control unit 80.

  As illustrated in FIG. 6, the cutting control unit 80 moves the slitter knife 67 (slitter knife 51) by the distance αe via the pulse motor 57 so as to follow the positional deviation amount α of the cutting line 18 c. The cutting position of the slitter knife 67 (the slitter knife 51) is made to exactly coincide with the cutting line 18c.

  Then, the sheet 18 is sent to the shape forming unit 8, and after the skew correction and the position adjustment in the width direction are performed, the sheet 18 is sent to the cutting unit 9 to accurately cut the blank at the position of the cutting line 18c. By performing the cutting process, the Z-fold pressure-bonded postcard 18Z is finally stored in the paper discharge storage unit 10.

  Thus, according to the pressure-bonded printed matter creating apparatus 1 of the present embodiment, the cutting position by the slitter knife 51 and the slitter knife 67 in the cutting unit 9 can be freely changed in the width direction of the sheet 18, Even if the position shift in the width direction of 18 occurs, accurate cutting at the predetermined cutting line 18c is always possible. In other words, the accuracy of the cutting dimensions such as the cutting width W1 at the cutting portion 9 is improved.

  As a result, for example, a part of the printed content of the Z-fold crimping postcard 18Z is cut out and lost by being cut shorter than the position of the predetermined cutting width W1, or the value of the cutting width W1 is an allowable value of the postal standard. It is possible to reliably prevent the occurrence of product defects that deviate from the range.

That is, according to the pressure-bonded printed material creating apparatus 1 of the present embodiment, it is possible to prevent a defective product of the pressure-bonded printed material such as the Z-fold pressure-bonded postcard 18Z due to a cutting error in the cutting and shaping of the cutting portion 9.
In addition, it is possible to produce a pressure-bonded printed material such as a Z-fold pressure-bonded postcard 18Z having a good external dimension accuracy such as the cutting width W1.

  Needless to say, the present invention is not limited to the configuration exemplified in the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention.

  For example, among the configurations of the crimped printed material creating apparatus 1 illustrated in the above-described embodiment, the Z-fold crimped postcard 18Z is created from the sheet 18 by the line sensor 40, the shape forming unit 8, the cutting unit 9, and the cutting control unit 80. You may comprise the crimped printed matter shaping apparatus which performs only the cutting shaping process after the crimping | compression-bonding process in that case.

  In the above description, the example in which the cutting position in the cutting unit 9 is variably controlled based on the detection result of the positional deviation in the width direction of the sheet 18 by the line sensor 40 has been described. The position deviation in the width direction of the sheet 18 may be corrected before being fed back to the cutting part 9 by feeding back to the position deviation correcting operation in the width direction in the section 8.

  In the above example, the slitter knife 51 and the slitter knife 67 are held by the bearing 52 and the bearing 68 and are slid on the fixed shaft 50 and the fixed shaft 65. However, the ball screws that can rotate the fixed shafts 50 and 65 are used. The slitter knives 51 and 67 may be moved by rotating the shaft.

At this time, the ball screw can be directly or indirectly rotated by a motor.
In the above-described embodiment, the combination of the worm 58 and the worm gear 61 is used in order to obtain high deceleration with respect to the rotation from the pulse motor 57. However, even if the motor and the rotation shaft 59 are parallel and decelerated by the geared motor. good.

  Further, although the pulse motor 57 is used as a drive source, a DC servo motor may be used.
