The present invention relates to a sheet processing apparatus for processing a sheet in the course of conveyance of the sheet.
In general, a sheet processing apparatus includes a plurality of processing parts provided along the conveyance direction. Then, as a type of the processing part, a conveyance directional processing part is known that is constructed such that a plurality of processing machines of two or more types are mounted and aligned in the width direction perpendicular to the conveyance direction of the sheet, that is, at the same position in the conveyance direction, so that processing along the conveyance direction is performed.
[Patent Document 1] JP 2012-91278 A
Meanwhile, in the conveyance directional processing part, the types and arrangement of the plurality of processing machines of two or more types need be settled such that the processing conditions may be satisfied. Nevertheless, in some cases, degraded processing machines need be exchanged into new processing machines or, alternatively, in association with a change in the processing conditions, original processing machines need be exchanged into processing machines of different types. In such cases, in the sheet processing apparatus of the conventional art, there has been a possibility that a mistake is made in the types and arrangement of the processing machines.
An object of the present invention is to provide a sheet processing apparatus in which even when processing machines are to be exchanged, processing machines can be mounted without a mistake in the types and arrangement.
The present invention is characterized by
a sheet processing apparatus for processing a sheet in the course of conveyance of the sheet, comprising:
a conveyance directional processing part for performing processing along the conveyance direction onto the sheet,
the conveyance directional processing part being constructed such that at the same position in the conveyance direction, a plurality of processing machines of two or more types are aligned in a width direction perpendicular to the conveyance direction and provided in a freely attachable and detachable manner;
a condition input part through which processing conditions in the conveyance directional processing part are inputted;
a display part for displaying the processing conditions; and
a processing machine selection control part for acquiring types and arrangement of the processing machines to be provided in the conveyance directional processing part such that the processing conditions may be satisfied and then displaying the acquired types and arrangement on the display part.
According to the present invention, when the processing conditions in the conveyance directional processing part are inputted, the processing machine selection control part is invoked so that the types and arrangement of the processing machines can automatically be determined. This avoids a situation that at the time of exchange of the processing machines, a mistake is made in the types and arrangement of the processing machines.
A sheet processing apparatus of the present invention is described below with reference to embodiments.
(Overall Configuration)
Further, in the sheet processing apparatus 1, a control part 6 for controlling the operation of the entire apparatus is provided in the inside of the apparatus body 10. The control part 6 is implemented by a CPU, a ROM, a RAM, or the like. An operation panel 60 is connected to the control part 6. Further, in the sheet processing apparatus 1, a trash box 110 for accommodating shreds (also including scraps) generated by the processing on the sheet is provided in the bottom of the apparatus body 10.
(Operation Panel)
Further, by virtue of the input part 601, the right end or the left end of the sheet in the width direction can be set as a reference position. Further, an Nth processing position which is an Nth cutting position counted from the reference position can be setup. Furthermore, a sheet piece to be excluded can be specified as a scrap. That is, the input part 601 serves also as a “reference position setting part 6011”, an “Nth position setting part 6012”, and a “scrap specifying part 6013”. Here, N is an integer greater than or equal to 1.
By using the reference position setting part 6011, the right end of the sheet in the width direction is set as the reference position L.
By using the Nth position setting part 6012, the Nth processing position is set up as a width WN measured from the reference position L.
By using the scrap specifying part 6013, sheet pieces to be excluded as scraps are specified from among the sheet pieces P1, P2, P3, P(n−1), Pn, PZ, and P(Z+1) having been processed. Employable methods for this specification include: (a) a method that a sheet piece having a width dimension D smaller than a predetermined value is “regarded as a scrap” and (b) a method that whether the sheet piece on the reference position L side of the Nth processing position and the sheet piece of the side distant from the reference position L at the Zth processing position are to be regarded as scraps is “selected by the operator”. Here, in the present embodiment, the method (a) and the method (b) may be combined together so that a part of sheet pieces may be specified as sheet pieces to be excluded as scraps by the method (b) and then the remaining sheet pieces may be specified as sheet pieces to be excluded as scraps by the method (a).
(Conveyance Directional Processing Part)
The conveyance directional processing part 4 is constructed such that a plurality of processing machines 7 of two or more types are provided and aligned in the width direction as shown in
As shown in
Further, a configuration is employed that one end side of the slide shafts 81 and 82 and the drive shaft 83 can be opened in an integrated manner without the necessity of a special tool and then the processing machine 7 can be put in or out through the one end side so as to be attached or detached. Thus, the processing machine 7 can easily be exchanged.
As the processing machines 7 of two or more types, for example, the following five types of processing machines can be employed.
(a) Right Type Slitter 71 (
(b) Left Type Slitter 72 (
(c) Longitudinal Crease Forming Machine 73 (
(d) Longitudinal Perforation Line Forming Machine 74 (
(e) Longitudinal Micro Perforation Line Forming Machine
A longitudinal micro perforation line forming machine has a similar configuration to the longitudinal perforation line forming machine 74. However, in comparison with the longitudinal perforation line forming machine 74, smaller acute angle tip parts 7411 are provided at a smaller pitch in the circumferential direction.
(Control Part)
The processing machine selection control part 61 includes: a slitter selection control part 611 for selecting a slitter; and a non-slitter selection control part 612 for selecting a processing machine other than a slitter. Then, as shown in
(a) Scrap Judging Part 62
The scrap judging part 62 judges whether the sheet piece formed on the reference position side or the counter-reference position side of the Nth processing position is a scrap. More specifically, the scrap judging part 62 includes a “first judgement part 621”, an “nth judgement part 622”, and a “Zth judgement part 623”.
The first judgment part 621, when N=1 is set up by the Nth position setting part, judges whether the sheet piece formed on the reference position side of the first processing position is a scrap.
The nth judgement part 622, when an integer n greater than or equal to 2 and smaller than Z is specified by the Nth position setting part, judges whether the sheet piece formed on the reference position side of the nth processing position is a scrap.
The Zth judgment part 623, when N=Z is set up by the Nth position setting part, judges whether the sheet piece formed on the counter-reference position side of the Zth processing position is a scrap.
(b) Slitter Selecting Part 63
The slitter selecting part 63 operates as described in the following (i) to (iv).
(i) When the judgment result of the scrap judging part 62 is “the sheet piece on the reference position side is a scrap” and the reference position is the right end L, the right type slitter 71 is selected as the slitter to be employed at the Nth processing position.
(ii) When the judgment result of the scrap judging part 62 is “the sheet piece on the reference position side is a scrap” and the reference position is the left end M, the left type slitter 72 is selected as the slitter to be employed at the Nth processing position.
(iii) When the judgment result of the scrap judging part 62 is “the sheet piece on the counter-reference position side is a scrap” and the reference position is the right end L, the left type slitter 72 is selected as the slitter to be employed at the Nth processing position.
(iv) When the judgment result of the scrap judging part 62 is “the sheet piece on the counter-reference position side is a scrap” and the reference position is the left end M, the right type slitter 71 is selected as the slitter to be employed at the Nth processing position.
Specifically, the slitter selecting part 63 includes a “first selection part 631”, an “nth selection part 632”, and a “Zth selection part 633”.
The first selection part 631, when the judgment result of the first judgement part 621 is “a scrap”, selects as the slitter to be employed at the first processing position the right type slitter 71 in a case that the reference position is the right end L or selects the left type slitter 72 in a case that the reference position is the left end M.
The nth selection part 632, when the judgment result of the nth judgement part 622 is “a scrap”, selects, in a case that the reference position is the right end L, the right type slitter 71 as the slitter to be employed at the nth processing position and the left type slitter 72 as the slitter to be employed at the (n−1)th processing position or selects, in a case that the reference position is the left end M, the left type slitter 72 as the slitter to be employed at the nth processing position and the right type slitter 71 as the slitter to be employed at the (n−1)th processing position.
The Zth selection part 633, when the judgment result of the Zth judgement part 623 is “a scrap”, selects as the slitter to be employed at the Zth processing position the left type slitter 72 in a case that the reference position is the right end L or selects the right type slitter 71 in a case that the reference position is the left end M.
Meanwhile, in a case that sheet pieces adjacent to each other in the width direction with the Nth processing position in between are both regarded as scraps, an inconsistency arises when the slitter selecting part 63 selects the slitter to be employed at the Nth processing position. Thus, (i) when processing conditions causing an inconsistency are inputted, an error is informed so that the operator is prompted to input appropriate processing conditions or (ii) restrictions are placed on the processing conditions inputted through the input part 601, so that a situation is avoided that sheet pieces adjacent to each other in the width direction with the Nth processing position in between are both specified as scraps.
(c) Slitter Source Number Storage Part 64
The slitter source number storage part 64 stores a source number T indicating the number of each of the right type slitters 71 and the left type slitters 72 prepared in advance.
(d) Slitter Remaining Number Storage Part 65
The slitter remaining number storage part 65, at each time that the right type slitter 71 or the left type slitter 72 is selected by the slitter selecting part 63, subtracts the selected one from the source number T so as to acquire a remaining number Q of each of the right type slitters 71 and the left type slitters 72 and then stores the acquired value.
(e) Slitter Determining Part 66
The slitter determining part 66, when the judgment result of the scrap judging part 62 is “the sheet piece on the reference position side is not a scrap”, determines that the slitter to be employed at the Nth processing position is “undetermined” or of the same type as the slitter to be employed at the (N−1)th processing position.
Specifically, the slitter determining part 66 includes a “first determination part 661” and an “nth determination part 662”.
The first determination part 661, when the judgment result of the first judgement part 621 is “not a scrap”, determines that the slitter to be employed at the first processing position is “undetermined”.
The nth determination part 662 is invoked when the judgment result of the nth judgement part 622 is “not a scrap”. Specifically, the nth determination part 662 includes an “nth α judgment part 6621”, an “nth α determination part 6622”, an “nth β judgment part 6623”, an “nth β determination part 6624”, and an “nth γ determination part 6625”.
The nth α judgment part 6621 judges whether a width dimension D of the sheet piece formed on the reference position side of the nth processing position is greater than a predetermined dimension B.
The nth α determination part 6622, when the judgment result of the nth α judgment part 6621 is “D>B”, determines that the slitter to be employed at the nth processing position is “undetermined”.
The nth β judgment part 6623, when the judgment result of the nth α judgment part 6621 is “D≤B”, judging whether the slitter to be employed at the (n−1)th processing position is “undetermined” and whether the remaining numbers of the right type slitters 71 and the left type slitters 72 are both one or greater.
The nth β determination part 6624, when the judgment result of the nth β judgment part 6623 is “yes”, determines that the slitter to be employed at the nth processing position is “undetermined”.
The nth γ determination part 6625, when the judgment result of the nth β judgment part 6623 is “no”, determines that the slitter to be employed at the nth processing position is of the same type as the slitter to be employed at the (n−1)th processing position.
Here, as shown in
(f) Undetermined Slitter Settling Part 67
The undetermined slitter settling part 67 settles the slitter to be employed at the Nth processing position and having been concluded as “undetermined” by the slitter determining part 66. Specifically, the undetermined slitter settling part 67 includes a “tentative arrangement part 671”, a “remain judging part 672”, a “tentative arrangement re-invoking part 673”, and a “tentative arrangement settling part 674”.
The tentative arrangement part 671 selects one from three patterns consisting of (i) the right type slitter 71 is adoptable, (ii) the left type slitter 72 is adoptable, and (iii) both the right type slitter 71 and the left type slitter 72 are adoptable as the slitter to be employed at the Nth processing position and having been concluded as “undetermined”, and then successively performs tentative arrangement.
The remain judging part 672 judges whether the number of each of the right type slitters 71 and the left type slitters 72 tentatively arranged falls within the range of the remaining number Q.
The tentative arrangement re-invoking part 673, when the judgment result of the remain judging part 672 is “not within the range of the remaining number Q”, re-invokes the tentative arrangement part 671 to newly perform tentative arrangement.
When the judgment result of the remain judging part 672 is “within the range of the remaining number Q”, the tentative arrangement is settled.
(Operation)
As an example, the following description is given for a case that the processing contents to be performed on the sheet are entirely cutting processing as shown in
(1) First, processing conditions are inputted through the input part 601. That is, first, the right end of the sheet in the width direction is set as the reference position L by using the reference position setting part 6011. Then, as shown in the display part 602 of
Specifically, as shown in the display part 602 of
(2) Further, at each time that the width directional distance WN of each of the processing positions X1 to X6 is inputted, when a SET 6021 in the display part 602 is pressed by using the input part 601, the processing machine selection control part 61 is invoked. This operation is described below with reference to the flow charts shown in
Here, in the flow charts, “Slit” indicates a slitter, “Slit 1” indicates the slitter at the first processing position X1, “Slit N” indicates the slitter at the Nth processing position, “R-blade” indicates the right type slitter 71, “L-blade” indicates the left type slitter 72, “N” is an integer greater than or equal to 1, “D” indicates a width dimension between adjacent processing positions, “A” indicates a maximum width dimension of a sheet piece regarded as a scrap and is 25 mm as described above, and “B” is a width dimension greater than “A” and is D3 mentioned above which is 48 mm in the present embodiment. Symbol “S” is an abbreviation to “step”. However, in the flow charts, the “N” in the steps concerning the operation at and after the second processing position is obviously an integer greater than or equal to 2.
First, as shown in
(2-1) First Processing Position X1
First, as shown in
In the present example, the sheet piece P1 is “a scrap”. Thus, the first selection part 631 selects the right type slitter 71 (S923) and then the slitter remaining number storage part 65 is invoked and subtracts one from the remaining number of the right type slitters 71 (S924).
Meanwhile, when the sheet piece P1 is “not a scrap”, the first determination part 661 is invoked and determines that the slitter to be employed at the first processing position X1 is “undetermined” (S925).
Then, it is judged whether input of processing conditions has been completed (S93). When the input is not completed, the procedure goes to input of a processing condition concerning the next processing position (S94). On the other hand, for example, in a case that cutting processing is to be performed at one position alone, the input is already completed. When the input has been completed, it is judged whether the slitter at the first processing position is “undetermined” (S931). In the case of “undetermined”, selection of the undetermined slitter at the first processing position (an additional operation 1 described later) is performed (S932). In the case of not being “undetermined”, the procedure is terminated.
(2-2) Second Processing Position X2
Then, as shown in
In the present example, the second processing position X2 is not the last processing position. Thus, the nth judgement part 622 is invoked and judges whether the sheet piece P2 is a scrap (S953). In this case, the judgment is achieved by judging whether the width dimension D of the sheet piece P2 is smaller than or equal to A mentioned above.
In the present example, D(50.0 mm)≥A is satisfied. Thus, the nth α judgment part 6621 is further invoked and judges whether D>B is satisfied (S954).
Here, in the present example, the sheet piece P1 is specified as a scrap. Thus, as for the second processing position X2, setup is performed such that an input satisfying D≤A is restricted. Accordingly, it is always judged as D>A. That is, it is judged that the sheet piece P2 is “not a scrap”.
Then, in the present example, D(50.0 mm)>B is satisfied. Thus, the nth α determination part 6622 is invoked and determines that the slitter to be employed at the second processing position X2 is “undetermined” (S9541). Here, in this case, subsequently, it is judged whether the slitter at the first processing position X1 immediately preceding the second processing position X2 is “undetermined” (S9542). In the present example, the slitter at the first processing position X1 has been determined as the right type slitter 71 and hence is not “undetermined”. Thus, after that, the slitter remaining number storage part 65 is invoked (S955) but the remaining number is not changed.
Meanwhile, when D≤B is satisfied, the nth β judgment part 6623 is invoked and judges whether the slitter at the first processing position X1 is “undetermined” and whether both the right type slitter 71 and the left type slitter 72 remain (S956). In the case of “undetermined” and “remain”, the nth determination part 6624 is invoked and determines that the slitter to be employed at the second processing position X2 is “undetermined” (S9561). In the case of not being “undetermined” or not “remain”, the slitter at the first processing position X1 and the slitter at the second processing position X2 are determined to be of the same type (S957). In each case, after that, the slitter remaining number storage part 65 is invoked (S955).
(2-3) Third Processing Position X3
Then, as shown in
In the present example, the third processing position X3 is not the last processing position. Thus, the nth judgement part 622 is invoked and judges whether the sheet piece P3 is a scrap (S953). In this case, the judgment is achieved by judging whether the width dimension D of the sheet piece P3 is smaller than or equal to A mentioned above.
In the present example, D(5.0 mm)≤A is satisfied. Thus, the slitter at the third processing position X3 is determined as the right type slitter 71 and the slitter at the second processing position X2 is determined as the left type slitter 72 (S9531). That is, a specification that the sheet piece P3 is regarded as a scrap is performed through the scrap specifying part 6013. After that, the slitter remaining number storage part 65 is invoked and reduces the remaining number of the right type slitters 71 and the remaining number of the left type slitters 72 by one each (S955).
Meanwhile, in the case of D>A, the nth α judgment part 6621 is further invoked and judges whether D>B is satisfied (S954).
(2-4) Fourth Processing Position X4
Then, as shown in
In the present example, the fourth processing position X4 is not the last processing position. Thus, the nth judgement part 622 is invoked and judges whether the sheet piece P4 is a scrap (S953). In this case, the judgment is achieved by judging whether the width dimension D of the sheet piece P4 is smaller than or equal to the width dimension A.
In the present example, D(50.0 mm)>A is satisfied. Thus, the nth α judgment part 6621 is further invoked and judges whether D>B is satisfied (S954).
Here, in the present example, the sheet piece P3 is specified as a scrap. Thus, as for the fourth processing position X4, setup is performed such that an input satisfying D≤A is restricted. Accordingly, it is always judged as D>A. That is, it is judged that the sheet piece P4 is “not a scrap”.
Then, in the present example, D(50.0 mm)>B is satisfied. Thus, the nth α determination part 6622 is invoked and determines that the slitter to be employed at the fourth processing position X4 is “undetermined” (S9541). Here, in this case, subsequently, it is judged whether the slitter at the third processing position X3 immediately preceding the fourth processing position X4 is “undetermined” (S9542). In the present example, the slitter at the third processing position X3 has been determined as the right type slitter 71 and hence is not “undetermined”. Thus, after that, the slitter remaining number storage part 65 is invoked (S955) but the remaining number is not changed.
Meanwhile, when D≤B is satisfied, the nth β judgment part 6623 is invoked and judges whether the slitter at the third processing position X3 is “undetermined” and whether both the right type slitter 71 and the left type slitter 72 remain (S956).
(2-5) Fifth Processing Position X5
Then, as shown in
In the present example, the fifth processing position X5 is not the last processing position. Thus, the nth judgement part 622 is invoked and judges whether the sheet piece P5 is a scrap (S953). In this case, the judgment is achieved by judging whether the width dimension D of the sheet piece P5 is smaller than or equal to A mentioned above.
In the present example, D(5.0 mm)≤A is satisfied. Thus, the slitter at the fifth processing position X5 is determined as the right type slitter 71 and the slitter at the fourth processing position X4 is determined as the left type slitter 72 (S9531). That is, a specification that the sheet piece P5 is regarded as a scrap is performed through the scrap specifying part 6013. After that, the slitter remaining number storage part 65 is invoked and reduces the remaining number of the right type slitters 71 and the remaining number of the left type slitters 72 by one each (S955).
Meanwhile, in the case of D>A, it is judged whether D>B is satisfied (S954).
(2-6) Sixth Processing Position X6
First, as shown in
In the present example, the sixth processing position X6 is the last processing position. Thus, the Zth judgement part 623 is invoked and judges whether the sheet piece P7 is a scrap (S958). Here, “with a left margin” indicates that the sheet piece at the leftmost end is to be excluded as a scrap.
In the present example, the sheet piece P7 is a scrap. Thus, the slitter at the sixth processing position X6 is determined as the left type slitter 72 (S959). Then, after that, the slitter remaining number storage part 65 is invoked subtracts one from the remaining number of the left type slitters 72 (S955).
Here, at the step of input of the second processing position X2 and at subsequent steps, at each time, as shown in
As a result of the above-mentioned operation, the slitters to be employed at the first to the sixth processing position X1 to X6 are determined as R-type, L-type, R-type, L-type, R-type, and L-type and then displayed on the display part 602 as shown in
(Additional Operation 1)
As shown in
(Additional Operation 2)
In the present example, the slitters to be employed at all processing positions have been determined. In contrast, in a case that a processing position is present that the slitter to be employed is concluded as “undetermined”, the undetermined slitter settling part 67 is invoked.
As shown in
(Additional Operation 3)
In the present example, after the slitter to be employed at the second processing position X2 or the fourth processing position X4 is concluded as “undetermined” (S9541), further, it is judged whether the slitter at the first processing position X1 or the third processing position X3 is “undetermined” (S9542). Then, the slitter at the first processing position X1 or the third processing position X3 has been determined as the right type slitter 71 and, hence, not “undetermined”. Thus, after that, the slitter remaining number storage part 65 is invoked (S955).
Nevertheless, in a case that the slitter at the first processing position X1 or the third processing position X3 is “undetermined”, that is, in a case that the slitter to be employed at the (N−1)th processing position is “undetermined” at the time of determination of the slitter to be employed at the Nth processing position, the following operation is performed.
First, it is judged whether the width dimension D between the (N−1)th processing position and the (N−2)th processing position is greater than the width dimension B (S9543).
In the case of D>B, the slitter to be employed at the (N−1)th processing position is determined as “both the right type slitter 71 and the left type slitter 72 are adoptable” (S9544). After that, the slitter remaining number storage part 65 is invoked (S955).
In the case of DB, it is judged whether the width dimension D is greater than the width dimension A, that is, whether A<D is satisfied (S9545). In the case that A<D is not satisfied, the procedure goes to S9544 and S955. In the case of A<D, it is judged whether the slitter to be employed at the (N−2)th processing position is the right type slitter 71 (S9546). Then, in the case of “no”, the procedure goes to S9544 and S955. In contrast, in the case of “yes”, the slitter to be employed at the (N−1)th processing position is determined as the right type slitter 71 (S9547) and then the procedure goes to S955.
(Change of Reference Position)
In the example given above, the right end of the sheet in the width direction has been set as the reference position L by using the reference position setting part 6011. Instead, in a case that the left end of the sheet width direction is desired to be set as the reference position L, each operation shown in
(Detailed Configuration of Slitter)
The upper rotary blade 701 is located at the left end of the upper housing 705 and cantilevered. A revolving shaft 7011 of the upper rotary blade 701 is supported by a tube-shaped bearing 7081 in a manner not permitting swing relative to the shaft center so that cantilevered supporting is achieved.
The lower rotary blade 702 is located near the left end of the lower housing 706 and cantilevered. Here, the lower rotary blade 702 is located on the right side of the upper rotary blade 701. A revolving shaft 7021 of the lower rotary blade 702 is supported by a tube-shaped bearing 7082 in a manner not permitting swing relative to the shaft center so that cantilevered supporting is achieved.
Then, in the left type slitter 72, the scrap exclusion member 703 is provided on the left side of the lower rotary blade 702. The scrap exclusion member 703 includes a sheet guide 7030 for going into contact with the sheet piece having been cut and for thereby guiding the sheet piece. When a lever 7031 is operated, the sheet guide 7030 can be displaced between an exclusion mode shown in
Here, the right type slitter 71 has a configuration right-left symmetric to the left type slitter 72.
(State Posterior to Operation)
The slitters which have been determined as described above and which are to be employed at the first to the sixth processing position X1 to X6 are displayed on the display part 602 as shown in
Here, in the right type slitter 71 at the first processing position X1, a margin guide 719 is provided on the right side so as to exclude more smoothly and reliably the sheet piece P1 serving as a scrap. Further, in the left type slitter 72 at the sixth processing position X6, a margin guide 729 is provided on the left side so as to exclude more smoothly and reliably the sheet piece P7 serving as a scrap.

(6) The reference position setting part 6011 may be not provided. In this case, any one alone of the right end and the left end in the sheet width direction may be adopted as the reference position and then stored in advance as an invariant into a storage part (not shown) of the control part 6. Here, in this case that the any one has been stored as the reference position, the alternatives listed in the given-above embodiments and selected when the other one is adopted as the reference position are not to be selected. Thus, such alternatives are unnecessary.
(7) The processing machine selection control part 61 may include: the slitter source number storage part 64; a slitter usage number storage part for, at each time that the right type slitter 71 or the left type slitter 72 is selected by the slitter selecting part 63, acquiring and storing a total number V of each of the right type slitters 71 and the left type slitters 72 having been selected; and a slitter settling part for comparing the source number T and the total number V with each other and then, when T>V is satisfied for the right type slitters 71, determining the “right type slitter 71” as the slitter to be employed and, when T>V is satisfied for the left type slitters 72, determining the “left type slitter 72” as the slitter to be employed. Here, in this case, the slitter determining part 66 and the undetermined slitter settling part 67 may not operate. However, in a case that these parts operate, the nth β judgment part 6623 of the slitter determining part 66 judges whether the slitter to be employed at the (n−1)th processing position is “undetermined” and T>V is satisfied when the source number T and the total number V are compared with each other. Further, the remain judging part 672 of the undetermined slitter settling part 67 judges whether a tentative total number Vs obtained by adding to the total number V the number of each of the right type slitters 71 and the left type slitters 72 tentatively arranged is smaller than the source number T.
(8) In the conveyance directional processing part provided in the sheet processing apparatus of the present invention, when a configuration is employed that a plurality of processing machines of two or more types can be provided and aligned in the width direction, a configuration is not excluded that a plurality of processing machines of one type selected from the two or more types of processing machines are provided and aligned in the width direction.

(12) The processing machine 7 may be constructed such that the processing blade itself can be exchanged. That is, when the processing machine 7 is to be exchanged, in place of exchanging the entire processing machine 7, the processing blade alone of the processing machine 7 may be exchanged. Here, the processing blade indicates the upper rotary blade 701, 731, 741, or the like. Specific examples are described below with reference to
In the sheet processing apparatus of the present invention, the types and arrangement of the processing machines to be provided in the conveyance directional processing part can automatically be determined. This avoids a situation that a mistake is made in the types and arrangement of the processing machines at the time of exchange of the processing machines. Accordingly, a high value is obtained in industrial utilization.
