(Action effect)
According to the sheet material processing apparatus 1 having the above configuration, the following effects can be exhibited.
(1) The edge cutting machine 2 separates both edge portions 101 from the sheet material 100, and the sheet material processing machine 3 forms perforations 301 and 302 on the subsequent sheet material 100A at two positions in the width direction. it can. At this time, in the sheet material processing machine 3, it is possible to form the perforations 301 and 302 at two positions at once by simply pressing the upper blade portion 42 against the lower blade portion 41 once. Therefore, the processing efficiency of the sheet material processing machine 3 and by extension, the processing efficiency of the sheet material processing apparatus 1 can be improved.

(2) As shown in FIG. 8, a cut mark 105 is generally printed on the sheet material 100 at a predetermined distance from the side edge 102 along the conveyance reference guide 108. When the cut mark 105 is printed at the correct position (reference S), the sheet material 100A after being cut by the edge cutting machine 2 is transferred to the sheet material processing machine 3 as shown in FIG. On the contrary, since the perforations 301 and 302 are located at the correct positions in the width direction, the perforations 301 and 302 are formed at the planned positions. However, in the printing process of a large number of sheet materials 100, as shown in FIG. 9, there are some cases in which the cut mark 105 is printed with a deviation from the correct position (reference S). In this case, as shown in FIG. 9, the rotary blades 21 and 22 of the edge cutting machine 2 move in the width direction to the position of the cut mark 105 to perform cutting, and the sheet material 100 to the sheet material 100B are cut. Is formed. However, since the sheet material 100B deviates from the reference S, when the sheet material processing machine 3 operates as it is, the perforations 301 and 302 are formed deviating from the planned positions. However, according to the sheet material processing machine 3 having the above configuration, the blade member 4 can be moved in the width direction (W1 direction in FIG. 9) by the moving mechanism 6, and therefore, as shown in FIG. 4 can be placed in the correct position with respect to the sheet material 100B, so that the perforations 301, 302 can be formed at the predetermined positions. Therefore, the processing in the width direction can be performed accurately.

(3) As shown in FIGS. 4 and 5, in the sheet material processing machine 3, since the blade member 4 is detachable, the blade member 4 can be changed to a different type of blade member 4. The difference in the type of the blade member 4 means that the type of processing of the processing blade 421 and / or the position of the processing blade 421 in the width direction and / or the number of processing blades 421 are different.

(4) As shown in FIG. 4, since the blade member 4 can be attached and detached by the slide mechanism, it can be easily and smoothly performed.

(5) As the blade member 4, not only the blade member 4 of FIG. 6 described above but also the blade member 4 of FIG. 11 and the blade member 4 of FIG. 14 as shown in another example described later may be used. it can. Therefore, the sheet material processing machine 3 can select and use any blade member 4 among these blade members 4, and thus can cope with various processing.

(Another example of blade member)
As the (A) blade member 4, a blade whose predetermined type of processing is cutting can be used. FIG. 11 is a front view of the blade member 4 of the first another example. FIG. 12 is a perspective view of the same. In this blade member 4, the upper blade portion 42 has a cutting blade as the processing blade 421 in the right side region of the region divided into two in the width direction, and the lower blade portion 41 has the upper blade portion 42. A cutting blade as a processing blade 411 is provided in a region facing the processing blade 421 from below. The blade member 4 is configured to perform cutting by rubbing the processing blade 411 and the processing blade 421 together. Therefore, according to the blade member 4, as shown in FIG. 13, the cut half 303 can be formed by cutting the right half of the sheet material 100 in the orthogonal direction.

(B) As the blade member 4, one in which the predetermined processing type is crease formation can be used. FIG. 14 is a front view of the blade member 4 of the second example. FIG. 15 is a perspective view of the same. In the blade member 4, the upper blade portion 42 has a crease blade as the processing blade 421 in the second and third regions from the left, that is, the central region, in the region divided into four in the width direction. The lower blade portion 41 has a receiving portion 411 of the processing blade 421 at least in a region facing the processing blade 421 of the upper blade portion 42 from below. Therefore, according to the blade member 4, as shown in FIG. 16, the crease 304 extending in the orthogonal direction can be formed in the central region of the sheet material 100.

(C) As the blade member 4, one in which the predetermined processing type is embossing can be used. FIG. 17 is a front sectional view of the working blade 421 and the receiving portion 411 of the blade member 4 of the third another example. FIG. 18 is a lower perspective view of the working blade 421 and the receiving portion 411. The receiving portion 411 is formed of a convex portion having a rectangular predetermined area, and the processing blade 421 is formed of a protruding portion along four sides of the receiving portion 411. With this blade member 4, as shown in FIG. 19, the convex portion 305 can be formed in a predetermined region of the sheet material 100.

(D) As the blade member 4, one in which the predetermined processing type is cutout formation can be used. FIG. 20 is a front sectional view of the working blade 421 and the lower blade portion 41 of the blade member 4 of the fourth another example. FIG. 21 is a lower perspective view of the working blade 421. The processing blade 421 is composed of projecting blades 4211, 4212, 4213, 4214 forming four sides of a rectangle, and has projecting blades 4212, 4214 on the opposite two sides with cutout portions 4215, 4216. With this blade member 4, as shown in FIG. 22, a cutout 306 can be formed in a predetermined region of the sheet material 100.

(Modification)
(1) In the above embodiment, the sheet material processing machine 3 performs processing at one location in the transport direction. However, the sheet material processing machine 3 may perform processing at a required number of two or more locations in the transport direction.

(2) In the above embodiment, the pressing mechanism 5 of the sheet material processing machine 3 is configured to press the upper blade portion 42 against the lower blade portion 41. However, the pressing mechanism 5 of the sheet material processing machine 3 may be configured to press the lower blade portion 41 against the upper blade portion 42, or may be configured to press the both blade portions 41, 42 against each other.

(3) The sheet material processing apparatus 1 may optionally include one or more of the following processing machines in addition to the edge processing machine 2 and the sheet material processing machine 3.
・ Conveyor direction cutter that cuts along the conveyor direction ・ Conveyor direction crease processor that forms creases along the conveyor direction ・ Conveyor direction perforator that forms perforations along the conveyor direction ・ Width direction Width cutting machine that cuts the entire width direction area by using the following: -Width direction crease processing machine that forms creases along the width direction in the entire width direction. Directional perforator

(4) In the above embodiment, the blade member 4 is configured to be attachable / detachable through the side plate opening (not shown) of the left side plate 33 in a state where the sheet material processing machine 3 is taken out from the receiving portion 110. . However, the blade member 4 may be configured to be attachable / detachable with the sheet material processing machine 3 installed in the receiving portion 110. In that case, the wall 112 of the apparatus main body 10 has a main body opening (not shown) at a position facing the side plate opening (not shown) of the left side plate 33, and the blade member 4 is It is attached and detached through the side plate opening and the main body opening.

(5) In the above embodiment, the drive unit 62 of the moving mechanism 6 is configured to move the blade member 4 by a motor (not shown). However, the drive unit 62 may be configured to manually move the blade member 4. Specifically, for example, an adjustment knob is provided instead of the gear 631 (FIG. 4). In this case, the user first tests one sheet material and confirms the deviation of the processing position. Then, if there is no deviation, processing is performed as it is. On the other hand, if there is a deviation, the adjustment knob is operated to move the blade member 4 in the width direction by the amount of deviation.

(6) In the above embodiment, the blade member 4 is configured such that both the lower blade portion 41 and the upper blade portion 42 move in the width direction. However, the blade member 4 may be configured such that only the lower blade portion 41 or only the upper blade portion 42 moves in the width direction. For example, when the upper blade portion 42 has the processing blade only in a part in the width direction and the lower blade portion 41 has the processing blade in the entire width direction, only the upper blade portion 42 has the width. It may be configured to move in a direction. In this case, specifically, the vertical cover 44 (FIG. 4) is vertically divided into two, and the upper vertical cover and the lower vertical cover are movable in the width direction by, for example, spline fitting, and A magnet 624 (FIG. 4) that is immovably engaged in the vertical direction is provided on the upper vertical cover that holds the upper blade portion 42. In addition, when the lower blade portion 41 has the processing blade only in a part in the width direction and the upper blade portion 42 has the processing blade in the entire width direction, the above is reversed, and the lower blade Only the part 41 is configured to move in the width direction.

(7) In the present invention, as shown in FIG. 9, when the cut mark 105 is printed with a deviation from the correct position (reference S), by moving the blade member 4 in the width direction, the deviation amount Is being corrected. And this invention may be comprised so that an error may be alert | reported, when the correction amount exceeds a limit value. Here, the “limit value” is the distance over which the blade member 4 can move in the width direction to the maximum extent. Further, “notifying an error” means, for example, displaying an uncorrectable warning on the operation panel or issuing a warning sound from a speaker. It should be noted that the present configuration can be adopted when the drive unit 62 of the moving mechanism 6 is operated by a motor or manually.
