  The fold forming unit 50 is received by the unit receiving portion 90 as shown by a one-dot chain line in FIG. After the folding mold forming unit 50 is received and positioned in the unit receiving portion 90, it is fastened to the flanges 9021 and 9031 on both sides of the unit receiving portion 90 with screws 9091 and 9092 at the flanges 5012 and 5013 on both sides. When the folding mold forming unit 50 is received in the unit receiving portion 90, the gear 5211 is connected to the gear 911, and the gear 5225 that is coaxial with the worm 5224 is connected to the gear 922.

Next, the operation of the sheet processing apparatus having the above configuration will be described.
First, sheets are sent out one by one from the bundle of sheets placed on the sheet feeding unit 11 to the conveyance path 20. Then, the sheet is conveyed by the conveying unit 2 and enters the cutting device unit 4.

  The cutting device unit 4 in a state where the cutting unit 40 is received in the unit receiving unit 70 operates as follows. That is, the motor 711 is operated by being turned on by the control means 6, and the driving force is transmitted to the crank 443 through the pulley 712, the gear 713, the gear 714, the gear 441, and the gear 442, and the operation of the crank 433 is performed. As a result, the movable blade 72 moves up and down, whereby the paper is cut. Unnecessary portions after cutting the paper, that is, cutting waste, are dropped down and stored in the trash box 101, and the remaining paper portions are transported next and enter the folding mold forming unit 5.

  The folding mold forming apparatus 5 in a state where the folding mold forming unit 50 is received in the unit receiving section 90 operates as follows. That is, when the control means 6 is turned on, the drive motor 912 is operated, and the driving force is transmitted through the pulley 918, the pulley 917, the gear 916, the gear 915, the gear 914, the gear 913, and the gear 911. The rotation shaft 521 rotates and the eccentric cam plates 5212 and 5213 rotate. On the other hand, since the upper die 511 is always urged upward by the springs 541 and 542, the bosses 5112 and 5113 are always in contact with the eccentric cam plates 5212 and 5213. Therefore, the upper die 511 has the eccentric cam plate. It moves up and down following the rotation of 5212 and 5213. When the rotation of the eccentric cam plates 5212 and 5213 is biased downward, the upper mold 511 moves downward, thereby forming a folding mold on the paper. Then, the folded sheet is conveyed to the next, and finally sent to the paper discharge unit 12.

  Further, in the folding mold forming unit 5, the depth of the folding mold to be formed can be adjusted. For this purpose, the processing means adjusting means is operated. That is, when the control means 6 is turned on, the drive motor 921 is operated to rotate the rotating shaft 522 via the gear 922, the gear 5225, the worm 5224, and the worm wheel 5221 and rotate the eccentric cam plates 5222 and 5223. . On the other hand, since the lower mold 512 is always urged downward by the springs 531 and 532, the bosses 5122 and 5123 are always in contact with the eccentric cam plates 5222 and 5223. Accordingly, the lower mold 512 moves up and down following the rotation of the eccentric cam plates 5222 and 5223. Thereby, the space | interval of the upper mold | type 511 and the lower mold | type 512 changes, Therefore, the depth of a folding mold | type changes. In order to obtain a desired depth, the operating time of the motor 921 may be set.

  As described above, in the paper processing apparatus 1 configured as described above, the paper is cut by the cutting device unit 4 in a direction orthogonal to the transport direction while being transported by the transport unit 2, and the folding mold forming device unit 5 is configured to perform the transport direction in the transport direction. A folding mold is formed in the orthogonal direction. In addition, before entering the cutting device unit 4, or between the cutting device unit 4 and the folding mold forming device unit 5, or after leaving the folding mold forming device unit 5, the sheet is processed by other processing means. You may receive processing.

  In the paper processing apparatus 1 having the above-described configuration, the cutting unit 40 that performs processing in the cutting apparatus unit 4 is provided detachably with respect to the apparatus body 10, so that the fixed blade 41 and the movable blade of the cutting apparatus unit 4 are provided. Even when 42 and the like need to be replaced due to wear or the like, the cutting unit 40 is detached from the unit receiving portion 70 of the apparatus main body 10, and a new cutting unit 40 prepared in advance is replaced with the unit receiving portion 70. The exchange can be performed simply by accepting it. Therefore, the time and labor required for the replacement work can be reduced.

  Further, since the folding mold forming unit 50 for performing processing in the folding mold forming apparatus section 5 is detachably provided to the apparatus main body 10, the upper mold 511, the lower mold 512 and the like of the folding mold forming apparatus section 5 are worn. Even if replacement is necessary for the reason, the folding mold forming unit 50 is detached from the unit receiving section 90 of the apparatus main body 10, and a new folding mold forming unit 50 prepared in advance is replaced with the unit receiving section 90. The exchange can be performed simply by accepting it. Therefore, the time and labor required for the replacement work can be reduced.

  Further, in the cutting device section 4 having the above-described configuration, the cutting unit 40 cannot be detached from the unit receiving section 70 unless the cover 81 is attached. In other words, the cutting unit 40 cannot be removed from the unit receiving portion 70 when it is not covered with the cover 81. Accordingly, it is possible to prevent the hand from touching the fixed blade 41 and the movable blade 42 when manually removing the cutting unit 40 from the unit receiving portion 70. Therefore, in the cutting device unit 4, the cutting unit 40 can be safely attached and detached. The folding mold forming unit 50 may be provided with a cover similar to the cover 81 of the cutting unit 40.

  Since the paper processing apparatus of the present invention can reduce the time and labor required for replacing the processing means, the industrial utility value is great.
