Then, the control unit 45 acquires the information from the first to fifth detection units 31 to 35, and based on the processing information of the sheet S set by the operation panel 46 or the reading unit 26, the supply unit 3 and the transport unit 4 and the drive of each processing unit are controlled to process the sheet S.

Further, the control unit 45 controls the timing at which the transfer by the transfer unit 4 is stopped in order to process the sheet in the processing unit 6 based on the detection result of the detection unit 10. Further, the control unit 45 sets the timing at which the transfer is stopped for processing the sheet S by the detection unit 10 installed on the downstream side of the installation position of the processing unit 6 or the processing unit 6 in the transfer path 5. Based on the detection result of the upstream transport position detecting unit that detects the transport position of the sheet installed on the upstream side of the installation position, it is determined according to the processing information of the sheet.

Further, when the control unit 45 controls the timing at which the transfer by the transfer unit 4 is stopped in order to process the sheet S, based on the detection result of the detection unit 10 installed on the downstream side of the processing unit 6. From the number of measurement steps of the transfer motor required to actually transfer the sheet S from the reference position on the upstream side of the detection unit 10 in the transfer path 5 to the installation position of the detection unit 10 and the reference position. The number of reference steps of the transfer motor corresponding to the distance to the detection unit 10 installation position can be compared, and the difference between the two can be used to correct the timing at which the seat S is stopped.

The reference position, which is the starting point of the measured value and the design value of the movement amount of the sheet S, is not particularly limited as long as it is installed on the upstream side of the detection unit 10 installed on the downstream side of the processing unit 6. Therefore, the reference position can be the installation position of the other detection unit 10 on the transport path 5, and can also be the installation position of the processing unit 6.

Specifically, when the machining process is a crease process and the fifth detection unit 35 is the detection unit 10 installed on the downstream side of the processing unit 6, the reference position is the front end of the paper feed table 52 and the reading unit. It can be either the installation position of the first to fourth detection units 31 to 34 or the crease processing unit 21 as another detection unit 10 for detecting the installation position of the 26 and the predetermined position of the sheet S. When the processing is a cutter processing and the fifth detection unit 35 is a detection unit installed on the downstream side of the processing unit 6, the reference position is the front end of the paper feed tray 52, the installation position of the reading unit 26, and the sheet. The installation position of the first to fourth detection units 31 to 34 as another detection unit 10 for detecting the predetermined position of S, the installation position of the crease processing unit 21 as the processing unit 6, and the installation position of the cutter processing unit 22. It can be either. Therefore, for example, the installation position of the fourth detection unit 34 can be used as a predetermined position on the upstream side of the fifth detection unit 35 by a predetermined amount, and another example is the installation position of the cutting blade 36 of the cutter processing unit 22. Be done.

[Sheet processing pattern]
FIG. 2 is a plan view showing an example of a processing pattern of the sheet S. The processing pattern shown in the figure is such that four processed objects Q having a broken line C are produced from one sheet S. Basically, four cutting lines T extending in parallel with the transport direction F, two folding lines C extending in the width direction W, and four cutting lines K extending in the width direction W are set. The two folded lines C and the cutting line K are formed by cutting the sheet S by the cutting line T in parallel with the transport direction F and removing the long pieces of paper Jm and Jc cut from the sheet S in the width direction W. It is formed by subjecting the cut pieces of the two sheets S arranged side by side to the crease treatment or the cutting treatment a plurality of times at the same time.

In the processing pattern of the sheet S shown in FIG. 2, since there are four cutting lines T parallel to the transport direction F by the slitter processing unit 29, the central unit 20b or the most downstream of the slitter processing unit 29. Only one of the units 20c of the above unit 20c is moved to a predetermined position in the width direction W for cutting processing, and the other is moved to the outside of the transport path 5 of the sheet S and is made to stand by.

Various processing information to be applied to the sheet S regarding the processing pattern of the sheet S is set by the user using the operation panel 46, or is recorded in the bar code M2 of the sheet S. .. The various processing information includes the size of the sheet S, the strength, the thickness, the type, the arrangement, the number and dimensions of the processed material Q, the size of the unnecessary piece J cut from the sheet S, and the transport direction. Information on the processing of the sheet S such as the length and number in a predetermined direction such as F and the width direction W is included.

[Overview of the overall work of the processing equipment]
(1) The user inputs various processing processing information from the operation panel 46 shown in FIG. In addition, instead of this manual input, or in cooperation with the manual input, the processing processing information can be automatically input by reading the barcode M2 or the like by the reading unit 26.

(2) A plurality of sheets S loaded on the supply table 52 of the supply unit 3 of FIG. 1 are supplied to the transfer path 5 one by one from the upper end by the suction transfer belt mechanism 51 and the paper feed roller 8. The supply speed is adjusted by the control unit 45 so as to be equal to the transport speed input as the machining processing information. Further, the control unit 45 controls the drive of the supply drive unit 47 and the transfer drive units 41 to 44 so that the seat S on the transfer path 5 is conveyed at a predetermined transfer speed. Then, when the control unit 45 temporarily stops the transfer of the sheet S for processing by the processing unit, the control unit 45 reduces the transfer speed by the transfer unit 4 at a predetermined rate and at a predetermined rate after the processing. Control to accelerate.

(3) When the sheet S is conveyed at a predetermined transfer speed by the transfer unit 4, when the sheet S reaches the reading unit 26, the position mark M1 of the sheet S and the bar code M2 are read if necessary. Various processing processing information to be applied to the sheet S is acquired.

(4) If the reject mechanism 25 cannot read by the reading unit 26 and the processing conditions are unknown, the reject mechanism 25 operates on the sheet S and drops the unreadable sheet S to drop the tray. Collect at 24.

(5) In the slitter processing unit 29, the sheet S is cut by the cutting blade 36 with a plurality of cutting lines T parallel to the transport direction F. Unnecessary pieces of paper Jm on the left and right edges cut from the sheet S by the most upstream unit 20a are moved downward to the lower paper piece collecting portion 23 by the margin dropping member 55, guided by the guide 69, and guided to the paper piece storage box. It is housed in 65.

(6) In the paper piece dropping mechanism 27, the unnecessary paper piece Jc cut from the sheet S by the central unit 20b and the most downstream unit 20c of the slitter processing unit 29 is moved downward to the lower paper piece collecting unit 23. It is stored in the paper piece storage box 65. After that, the front end Sf of the seat S is detected at the fourth detection unit 34 installation position.

(7) In the crease processing unit 21, when the folding line C forming position of the sheet S approaches the installation position of the folding mold 37, the control unit 45 controls the driving of the paper feeding drive unit 47 and the transport drive units 41 to 44. , The transfer speed by the supply unit 3 and the transfer unit 4 is started to be decelerated at a predetermined ratio, and then when the folding line C forming position of the sheet S reaches the installation position of the folding mold 37, the transfer of the sheet S is stopped in the entire apparatus.

The timing at which the control unit 45 starts decelerating the transport unit 4 to form the broken line C is set on the most downstream side of the first to fourth detection units 31 to 34 installed on the upstream side of the crease processing unit 21. The time point at which the front end Sf of the sheet S is detected by the fourth detection unit 34 closest to the crease processing unit 21 is preferably used as a reference. By using the detection result of the fourth detection unit 34 as the reference for sheet transfer, even if the transfer path 5 becomes long and the positional deviation of the sheet S on the transfer path 5 in the transfer direction F occurs, the first detection unit The sheet position information obtained by the 31 and the reading unit 26 can be modified to make the sheet position information more accurate.

Then, the control unit 45 drives the folding type driving unit 49, lowers the convex type 38, and inserts the convex type 38 into the concave portion of the concave type 39 to form a folding line C along the width direction W with respect to the sheet S. .. After that, by continuing to drive the folding type driving unit 49, the convex type 38 that has reached the bottom dead center is raised. Then, the driving of the paper feeding drive unit 47 and the transfer drive units 41 to 44 is restarted, and the sheet S is conveyed to the downstream side.

(8) In the cutter processing unit 22, when the cutting line K forming position of the sheet S approaches the installation position of the cutting blade 36, the control unit 45 controls the driving of the paper feeding drive unit 47 and the transport drive units 41 to 44. Then, the transfer speed by the supply unit 3 and the transfer unit 4 is started to be decelerated at a predetermined rate.

The timing at which the deceleration of the transport unit 4 is started in order to form the cutting line K is based on the time when the front end Sf of the sheet S is detected by the fourth detection unit 34, as in the processing process by the crease processing unit 21 described above. It is preferable to do so. As a result, even if the transport path 5 becomes long and the position shift of the sheet S on the transport path 5 in the transport direction F is accumulated, the sheet position information can be corrected, and the sheet position information can be made more accurate. Can be.

When the forming position of the cutting line K reaches the installation position of the cutting blade 36, the control unit 45 stops driving the paper feeding drive unit 47 and the transfer drive units 41 to 44, and the sheet S is conveyed by the transfer unit 4. Stop the entire device. Then, the control unit 45 drives the cutting drive unit 50 to lower the upper movable blade 71 and bring it into contact with the lower fixed blade 73 to cut the sheet S along the width direction W.

In the processing pattern shown in FIG. 2, when the cutting process is executed on the frontmost side, that is, the first cutting line K1 on the most downstream side in the transport direction F among the plurality of cutting lines K1 to K4 formed on the sheet S. , An unnecessary piece of paper Jf at the front end portion of the sheet S is cut off, falls downward, is guided to the dust collecting unit 23 by the guide 70, and is housed. The control unit 45 continues to drive the cutting drive unit 50 even after the paper piece Jf is cut, so that the upper movable blade 71 at the bottom dead center rises to the top dead center.

After the cutting process on the first cutting line K1, when the second to fourth cutting lines K2 to K4 set on the downstream side in the transport direction F from the first cutting line K1 are cut, the control unit 45 performs the cutting process. Therefore, in the present embodiment, the reference of the timing for stopping the transport of the sheet S is the detection result of the fifth detection unit 35 instead of the fourth detection unit 34.

Regarding the sheet transfer stop timing based on the detection result of the fifth detection unit 35, in the present embodiment, the control unit 45 uses the installation position of the cutting blade 36 as the reference position. Then, the measured value of the movement amount of the sheet S required to actually convey the sheet S from the installation position of the cutting blade 36 to the installation position of the fifth detection unit 35, that is, the measured value of the drive amount of the transfer drive unit 43, The design value of the movement amount of the sheet corresponding to the distance from the cutting blade 36 installation position to the installation position of the fifth detection unit 35, that is, the design value of the drive amount of the transport drive unit 43 is compared.

Then, the difference between the measured value and the design value is used to correct the timing at which the sheet S is stopped for the cutting process in the cutter processing unit 22. Here, in the present embodiment, the paper feed drive unit 47 and all the transfer drive units 41 to 44 are driven synchronously, but the transfer drive unit to be the target for comparing the measured value and the design value is It is a transport drive unit 43 that rotationally drives the transport rollers of the eighth transport unit 18 and the ninth transport unit 19 installed before and after the cutter processing unit 22.

FIG. 3 shows a flow when the control unit 45 controls the timing for stopping the transfer by the transfer unit 4 in order to cut the sheet S in the cutter processing unit 22 based on the detection result of the fifth detection unit 35. .. In step S101 of FIG. 3, the control unit 45 drives the transport drive unit 43 that has been stopped after forming the first cutting line K1.

As a result, the transfer rollers of the 7th to 9th transfer units 17 to 19 installed before and after the crease processing unit 21 and the cutter processing unit 22 are rotated, and the transfer of the sheet S is restarted. At this time, the paper feed drive unit 47 for driving the paper feed unit 8 installed on the upstream side of the crease processing unit 21 and the cutter processing unit 22, and the transfer drive unit 41 for driving the first to sixth transfer units 11 to 16. The transfer drive unit 44 that drives the tenth transfer unit 20 installed on the downstream side of the 42 and the transfer drive unit 44 is also restarted in synchronization with the drive of the transfer drive unit 43, and the transfer of the sheet S is restarted in the entire apparatus.

In step S102, the drive amount of the transfer drive unit 43 from the restart of the drive of the transfer drive unit 43 in step S101 is measured. When all or a part of the transfer motors constituting the transfer drive units 41 to 44 are composed of a stepping motor, a servomotor, or the like, the drive amount of the transfer drive unit 43 is a pulse signal of these transfer drive units 43. It can be measured by counting the number of measurement steps of. When the transfer motor is composed of a DC motor or the like, measurement can be performed by counting the number of measurement steps of the encoder installed on the drive shaft of the transfer drive unit 43. Further, it is also possible to measure or calculate the transport speed of the transport unit 4 when transporting the sheet S, count the transport time, and calculate the drive amount of the transport drive unit 43 from these.

In step S103, it is determined whether or not the cutting process to be performed next in the cutter processing unit 22 corresponds to the rear end Qr of the processed object Q. When the next cutting process is an operation of forming the rear end Qr of the machined object Q, the transport amount of the sheet S is strictly controlled, the cutting process is performed at a position where there is no deviation, and the machined object Q is transported. It is necessary to improve the accuracy of the length in the direction F. On the other hand, when the cutting process is not an operation of forming the rear end Qr of the processed object Q, that is, when it is the front end Qf of the processed object Q in the processing pattern shown in FIG. 2, such a cutting process is performed. It is an unnecessary piece of paper Jd that is cut off from the sheet S. The cut unnecessary piece of paper Jd is removed from the transport path 5 after the cutting process, and is collected by the lower paper material collecting unit 23. Strict control of the length of the transport direction F is not required for this unnecessary piece of paper Jd.

When the next cutting process corresponds to the front end Qf of the processed object Q and does not satisfy step S103, the sheet S is processed by the transfer unit 4 according to the detection result of the fifth detection unit 35. It is decided that the control for correcting the stop timing is not performed, and the process proceeds to step S108. On the other hand, when the condition of step S103 is satisfied, the process proceeds to step S104.

The control unit 45 monitors whether or not the fifth detection unit 35 has detected the front end Sf of the sheet S transported downstream from the cutter processing unit 22 as the drive of the transport drive unit 43 resumes. In step S104, it is determined whether or not the fifth detection unit 35 has detected the front end Sf of the sheet S. Until the portion that becomes the front end Sf of the sheet S by being cut reaches the position where the fifth detection unit 35 is installed, step S104 is not satisfied and the process proceeds to step S108. When the fifth detection unit 35 detects the front end Sf of the sheet S, the process proceeds to step S105.

In step S105, the measured value of the drive amount of the transfer drive unit 43 actually required while the front end Sf of the sheet S is transferred from the installation position of the cutting blade 36 to the installation position of the fifth detection unit 35, and the transfer path 5 Compare with the design value of the drive amount of the transport drive unit 43 stored in advance based on the distance from the cutting blade 36 to the fifth detection unit 35 in the above. Then, in step S106, the difference between the measured value and the design value is calculated, and the timing at which the transfer of the sheet S is stopped is corrected.

At the time of correction, the difference between the measured value and the design value is added / subtracted to the remaining drive amount of the transport drive unit 43. The remaining drive amount is the transport direction F from the predetermined position Sp of the sheet Sa located at the cutting blade 36 installation position to the second cutting line K2 when the front end Sf of the sheet S reaches the fifth detection unit 35 installation position. It is a design value of the drive amount of the transport drive unit 43 corresponding to the length Lh of.

Specifically, for example, it is assumed that the length Lq of the processed object Q in the transport direction F is 50 mm, and the distance from the cutting blade 36 installation position to the fifth detection unit 35 installation position is 40 mm. Further, the transport drive unit 43 is configured by a stepping motor. It is assumed that the reference number of steps of the transport drive unit 43 in design for transporting the seat S by a distance of 40 mm is 2000 pulses. Then, the number of measurement steps of the transport drive unit 43 required to actually transport the sheet S and transport the front end Sf of the sheet S from the cutting blade 36 installation position to the fifth detection unit 35 installation position is 2100 pulses. Suppose.

The difference between the measured value and the design value is 100 pulses. The arrival of the seat S at the fifth detection unit 35 installation position is delayed due to the transfer roller slipping by the amount of 100 pulses, and the control unit 45 drives the transfer drive unit 43 more than the design value. .. Therefore, the control unit 45 adds 100 pulses to the number of remaining steps of the transport drive unit 43 required to transport the seat S by the remaining 10 mm. As a result, in addition to the number of remaining steps required to further convey the sheet S after the detection of the fifth detection unit 35 and stop the sheet S at the position where the second cutting line K2 is formed, the transfer drive is increased by 100 pulses. Correct so that the unit 43 is driven.

On the contrary, when the measured value is smaller than the design value as a result of comparison in step S105, it is assumed that the sheet S is located downstream from the design transport position due to an impact at the time of cutting or the like. It is considered that the formation position of the cutting line K reaches the cutting blade 36 installation position earlier. At this time, the difference between the design value and the measured value is corrected so as to be subtracted from the design value. As a result, the drive amount of the transport drive unit 43 until the transport stop for the post-detection cutting process of the fifth detection unit 35 can be reduced. Therefore, even if the actual transport position of the sheet S deviates to the downstream side from the design, the accuracy of the length of the machined object Q in the transport direction F can be maintained.

In step S107, the control unit 45 drives the transport drive unit 43 by the corrected remaining drive amount obtained by correcting the remaining drive amount in the design. In step S108, it is determined whether or not the formation position of the cutting line K of the sheet S has reached the installation position of the cutting blade 36. When the remaining drive amount of the transport drive unit 43 is corrected in step S106, in step S108, when the measured value of the drive amount of the transport drive unit 43 reaches a predetermined value which is the corrected remaining drive amount, the step is taken. S108 will be satisfied. On the other hand, if step S103 or step S104 is not satisfied and the process proceeds to step S108, when the measured value of the drive amount of the transport drive unit 43 reaches the design value stored in advance, step S108 is satisfied. Become.

While the cutting line K forming position has not yet reached the installation position of the cutting blade 36 in step S108, step S108 is not satisfied and the process returns to step S102. When the cutting line K forming position reaches the installation position of the cutting blade 36, step S108 is satisfied and the process proceeds to step S109.

In step S109, the control unit 45 stops the transport drive unit 43 in order to perform the cutting process, and stops the transport of the sheet S. In step S110, the control unit 45 resets the drive amount of the transport drive unit 43. In step S111, the control unit 45 drives the cutting drive unit 50, lowers the upper movable blade 71, and cuts the sheet S from the lower fixed blade 73 along the width direction W. This completes the operation of the cutting process for correcting the timing for stopping the transfer in order to perform the cutting process for the sheet S based on the detection result of the fifth detection unit 35.

When the cutting process is performed on the second cutting line K2, the downstream portion of the sheet S is cut off from the upstream portion. After that, the control unit 45 restarts the drive of the transport drive units 41 to 44. The downstream portion of the cut sheet S is transported downstream on the transport path 5 by the 9th transport section 19 and the 10th transport section 20, discharged to the mounting section 2, and processed product Q on the mounting table 57. It is placed as.

On the other hand, in order to form the third cutting line K3 set next to the second cutting line K2, the upstream portion of the sheet S is processed again according to the flow shown in FIG. In step S101 of FIG. 3, the control unit 45 restarts the drive of the transport drive units 41 to 44 that had been stopped to form the second cutting line K2. The cutter processing unit 22 also resumes driving the transport drive unit 43.

Similar to the case of forming the second cutting line K2, the drive amount of the transfer drive unit 43 from the restart of the drive of the transfer drive unit 43 is measured in step S102. In step S103, it is determined whether or not the cutting process to be performed next in the cutter processing unit 22 corresponds to the rear end Qr of the processed object Q. The third cutting line K3 corresponds to the front end Qf of the machined product Q. Therefore, the process proceeds to step S108 without satisfying step S103.

In step S108, it is determined whether or not the forming position of the cutting line K3, which is the processing position of the sheet S, has reached the installation position of the cutting blade 36. In order to determine that the third cutting line K3 has reached the installation position of the cutting blade 36, the drive amount of the transport drive unit 43 measured in step S102, that is, after the time of the cutting process for forming the second cutting line K2. The drive amount of the transfer drive unit 43 is set to the design value of the drive amount of the transfer drive unit 43 corresponding to the length Ld from the second cutting line K2 to the third cutting line K3 set in the processing information of the sheet S. It is necessary to reach.

As described above, when the control unit 45 forms the third cutting line K, the control unit 45 cuts the cutter based on the time when the second cutting line K2 is formed, which is the time immediately before the processing in the cutter processing unit 22 as the processing unit 6. Since the processing unit 22 forms the third cutting line K3, it is possible to control the timing at which the transfer by the transfer unit 4 is stopped. From this, the third cutting line K3 can be properly formed.

As another example of the method of determining that the third cutting line K3 in step S108 has reached the installation position of the cutting blade 36, the transport driving unit 43 from the time when the fourth detecting unit 34 detects the front end Sf of the sheet S. The drive amount is the length L3 from the front end Sf of the sheet S set in the machining processing information to the third cutting line K3 at the distance from the installation position of the fourth detection unit 34 to the installation position of the cutting blade 36 in the transport path 5. It is also possible to set the time when the design drive amount corresponding to the value obtained by addition is reached.

The process returns to step S102 without satisfying step S108 until the third cutting line K3 forming position reaches the installation position of the cutting blade 36. When the third cutting line K3 forming position reaches the installation position of the cutting blade 36, step S108 is satisfied and the process proceeds to step S109. The operation of steps S109 to S111 is the same as that at the time of forming the second cutting line K2.

In this way, the control unit 45 determines whether or not the timing for stopping the transfer for cutting the sheet S is determined based on the detection result of the fifth detection unit 35 according to the processing information of the sheet S. .. In the processing pattern shown in FIG. 2, the first cutting line K1 having a short length L1 from the front end Sf of the sheet S preferably sets the measured value of the drive amount of the transport drive unit 43 from the detection time of the fourth detection unit 34. By comparing with the design value, the transport stop timing is determined based on the detection result of the fourth detection unit 34. In the second and fourth cutting lines K2 and K4, which are the rear ends of the machined object Q, the transfer stop timing is determined based on the cutting process time of the cutter processing unit 22 immediately before the front end Qf of the machined object Q. Then, the third cutting line K3 may determine the transport stop timing from either the cutting processing time of the cutter processing unit 22 or the detection time of the fourth detection unit 34.

Since it is determined according to the processing information of the sheet whether or not the timing to stop the transfer for processing the sheet S is determined based on the detection result of the fifth detection unit 35, the rear end of the processed object Q is determined. Only when it is necessary to improve the accuracy, or when the sheet S can be detected by the 5th detection unit 35 according to the machining processing information, the drive amount of the transport drive unit 43 is based on the detection result of the 5th detection unit 35. Can be corrected. Therefore, the sheet S can be efficiently processed.

From the above, the processing apparatus 100 according to the first embodiment cuts the sheet S in the cutter processing unit 22 based on the detection result of the fifth detection unit 35 installed on the downstream side of the cutter processing unit 22. Since the timing at which the transfer by the transfer unit 4 is stopped is controlled, the accuracy of the cutting position can be improved. In particular, when the transport speed of the transport unit 4 is high, the timing at which the transport is stopped shifts, so that the length Lq of the processed product Q obtained by the cutting process in the transport direction F tends to vary. However, in the present embodiment, since the timing for stopping the transport is corrected, it is possible to cut at a more accurate cutting position.

Further, since the transport unit 4 includes a ninth transport unit 19 configured as a detection upstream side transport unit installed between the cutter processing unit 22 and the fifth detection unit 35 on the transport path 5, the transport unit 4 is provided. The sheet S sandwiched and transported by the ninth transport unit 19 can be cut with high accuracy. In particular, as shown in FIG. 2, when the cutting line K set relatively upstream in the transport direction F of the sheet S is formed, the accuracy of the cutting position tends to decrease. The reason is that when the cutting line K set relatively upstream in the transport direction F of the sheet S is formed, the seventh transport section 17 and the eighth transport section installed on the upstream side of the cutter processing section 22 This is because the sandwiching and transporting of the sheet S by 18 may no longer be performed.

For example, when the fourth cutting line K4 of FIG. 2 is formed, the length L5 from the fourth cutting line K4 to the rear end Sr of the sheet S is set to be relatively short, so that the fourth cutting line K4 is formed. At this time, the rear end of the sheet S may not reach the nip portion of the transport roller of the eighth transport portion 18 on the upstream side of the installation position of the cutting blade 36. If the sheet S is no longer sandwiched and transported by the eighth transport section 18 before the fourth cutting line K4 forming position reaches the installation position of the cutting blade 36, the sheet S will hold the ninth transport section 19 on the downstream side for a while. It will be sandwiched and transported only by the constituent transport rollers.

Normally, each of the transport rollers constituting the transport unit 4 has slightly different eccentricity of the rotating shaft and a state of wear on the surface. When a plurality of transport units 11 to 20 are installed on the transport path 5, a slight difference may occur in the transport amount of each transport unit 11 to 20. Further, even when the type of the sheet S is a slip-prone material or a surface-processed material, the transfer amount of the sheet S may differ between the front and rear transfer units 11 to 20. .. Therefore, for example, there may be a problem that the cutting position formed on the sheet S is deviated by about 0.4 mm. If the transport state is different between the 8th transport section 18 on the upstream side and the 9th transport section 19 on the downstream side of the cutter processing section 22, the transport amounts of the two are different from each other, and the accuracy of the cutting position is lowered. Let me.

Even in such a situation, if the sheet S is sandwiched and conveyed by both the eighth transport section 18 on the upstream side and the ninth transport section 19 on the downstream side of the cutter processing section 22 immediately before the formation of the cutting line K, the cutting process is performed. At this time, the sheet S is stable and the deviation of the cutting position is relatively small. However, when the cutting line K set on the upstream side portion of the sheet S is formed, the sheet S is no longer sandwiched and transported by the eighth transport unit 18, and the sheet S is sandwiched and transported only by the ninth transport unit 19. In this case, the difference between the transport state of the 8th transport unit 18 and the transport state of the 9th transport unit 19 is likely to be significantly affected, and the deviation of the cutting position is likely to be large.

Therefore, in the present embodiment, the fifth detection unit 35 is installed on the downstream side from the installation position of the ninth transport unit 19, and the sheet S is transported in order to cut the sheet S based on the detection result of the fifth detection unit 35. Control when to stop. As a result, the transport amount of the transport drive unit 43 can be corrected in consideration of the transport state of the sheet S by the ninth transport unit 19, and the deviation of the cutting position can be reduced.

Then, the control unit 45 determines whether or not the timing for stopping the transfer for processing the sheet S is determined based on the detection result of the fifth detection unit 35 according to the processing information of the sheet S. According to the processing information, only the processing that requires high accuracy for the processing position and the processing that is set at the place where the stop position of the sheet S is likely to shift is the fifth on the downstream side of the processing unit 6. The timing for stopping the transfer can be determined based on the detection result of the detection unit 35.

Further, the control unit 45 actually conveys the sheet S from the cutting blade 36 installation position, which is a reference position on the upstream side of the fifth detection unit 35 installation position in the transfer path 5, to the fifth detection unit 35 installation position. Compare the measured value of the drive amount of the transport drive unit 43 required for the above with the design value of the drive amount of the transport drive unit 43 corresponding to the distance from the cutting blade 36 installation position to the fifth detection unit 35 installation position. Since the difference between the above is used to correct the timing at which the seat S is stopped, the drive amount of the transport drive unit 43 can be appropriately corrected.

Further, the range in which the measured value of the drive amount of the transport drive unit 43 required to actually transport the sheet S is compared with the design value is set in the range where the fifth detection unit 35 is installed from the cutting blade 36 installation position of the cutter processing unit 22. Since it is set to the position, the stop timing for cutting is corrected by using the drive amount of the transport drive unit 43 from the time when the sheet S is cut to the time when the front end Sf of the sheet S passes through the fifth detection unit 35 installation position. can do. Therefore, the drive amount can be measured easily and accurately. In particular, since the time point at which the measurement of the drive amount of the transfer drive unit 43 is started can be set to the point at which the transfer of the sheet S is stopped due to the cutting process, the sheet S can be conveyed at high speed. It is possible to measure more accurately than when the time point at which the front end Sf of the above is detected is set as the measurement start time point.

Further, the fifth detection unit 35 is located at a position where the distance from the installation position of the cutting blade 36 in the transfer path 5 to the installation position of the fifth detection unit 35 is slightly shorter than the length in the transport direction of the processed material in which the cutting position tends to vary. Can be adjusted to install. From this, the fifth detection unit 35 can detect the front end Sf of the sheet S after starting the deceleration of the transfer speed by the transfer unit 4 for the cutting process forming the rear end Qr of the processed product Q. In a situation where the sheet S is being conveyed at high speed, the detection accuracy by the fifth detection unit 35 can be improved as compared with the case where the front end Sf of the sheet S is detected.

Further, since the fifth detection unit 35 detects the front end Sf of the seat S, the transport position of the seat S can be accurately and easily grasped. In addition, an inexpensive optical sensor can be used, and the cost can be reduced.

(Second embodiment)
FIG. 4 is a schematic vertical sectional view of the processing apparatus 100a according to the second embodiment. In the first embodiment, the ninth transport unit 19 is rotationally driven by the transport drive unit 43 together with the seventh and eighth transport units 17 and 18 on the upstream side. However, in the second embodiment shown in FIG. Then, the ninth transport drive unit 19a is rotationally driven by the transport drive unit 44a together with the tenth transport unit 20a on the downstream side. Both the 9th transport section 19a and the 10th transport section 20a constitute a machining downstream side transport section installed on the transport path 5a on the downstream side of the cutter processing section 22 as the machining processing section 6.

FIG. 5 is a plan view showing an example of a processing pattern of the sheet S according to the second embodiment. In the processing pattern of the sheet Sa shown in FIG. 5, four cutting lines T parallel to the transport direction F and two cutting lines K1a and K2a parallel to the width direction W are set, and six cutting lines K1a and K2a are set. Processed objects Qa1 to Qa3 are arranged. No fold line C is set on the sheet Sa.

Further, it shows a case where the barcode M2 is not printed because an unnecessary piece of paper J is not set at the front end portion of the sheet Sa. Therefore, when the sheet Sa is processed, the processing information is manually input and set from the operation panel 46. However, if necessary, the barcode M2 may be printed on the sheet Sa and read by the reading unit 26.

In FIG. 5, long unnecessary pieces of paper Jm and Jc are set in the transport direction F cut from the sheet Sa by forming the cutting line T in the slitter processing unit 29. However, a long unnecessary piece of paper J is not set before and after the processed product Qa in the width direction W of the sheet Sa.

Therefore, when the fifth detection unit 35 detects the sheet Sa to be conveyed back and forth after the cutting process by the cutter processing unit 22, the rear end Sar of the preceding sheet Sa and the front end Saf of the succeeding sheet Sa The sheet Sa is continuously conveyed between them without interruption. Therefore, the light from the light emitting element constituting the fifth detection unit 35a does not reach the light receiving element, and it becomes difficult to detect the rear end Sar and the front end Saf of the sheet Sa after the cutting process.

Therefore, in the second embodiment, the control unit 45a sets the transfer speed of the sheet Sa that is previously conveyed by the ninth and tenth transfer units 19a and 20a as the processing downstream side transfer unit to the subsequent sheet Sa. The transport drive units 43a and 44a are controlled so as to be faster. Then, the preceding sheet Sa is quickly discharged to the mounting table 57. In order to perform such control, the transport drive unit 44a that drives the ninth and tenth transport units 19a and 20a rotationally drives the seventh and eighth transport units 17a and 18a on the upstream side of the cutter processing unit 22. It is installed separately from the transport drive unit 43a.

Further, the control unit 45a is a reference position on the upstream side of the fifth detection unit 35 in the transfer path 5 determined to compare the measured value of the actual drive amount of the transfer drive unit 43a with the design value. Was set as the cutting blade 36 installation position in the first embodiment, but in the second embodiment, the reference position is set as the installation position of the fourth detection unit 34.

The operation of the second embodiment will be described. The sheet Sa is supplied to the transport path 5a by the supply unit 3, cut by the slitter processing unit 29 along the cutting line T parallel to the transport direction F, and unnecessary paper pieces Jm and Jc are collected by the paper piece collection unit 23. Is operated in the same manner as in the first embodiment.

FIG. 6 shows a flow related to the operation on the downstream side of the fourth detection unit 34 installation position of the transport path 5a in the second embodiment. In step S201 of FIG. 6, the control unit 45a determines whether or not the fourth detection unit 34 has detected the front end Saf of the sheet Sa. Until the fourth detection unit 34 detects the front end Saf of the sheet Sa, the process ends.

When the fourth detection unit 34 detects the front end Saf of the sheet Sa, the process proceeds to step S202, and the drive amount of the transport drive unit 43a from the time when the fourth detection unit 34 detects the front end Saf of the sheet Sa in step S201 is measured. .. In step S203, it is determined whether or not the cutting process to be performed next in the cutter processing unit 22 corresponds to the rear end Qar of the processed product Qa. In the machining processing pattern set on the sheet Sa shown in FIG. 5, the first cutting line K1a corresponds to the rear end Qar of the preceding machining processing product Qa1 and also corresponds to the front end Qaf of the subsequent machining processing product Qa2. In this case, step S203 is satisfied, and the process proceeds to step S204.

In step S204, it is determined whether or not the fifth detection unit 35 has detected the front end Saf of the sheet Sa. Until the front end Saf of the sheet Sa is conveyed to the installation position of the fifth detection unit 35, step S204 is not satisfied and the process proceeds to step S208. When the front end Saf of the sheet Sa is conveyed to the installation position of the fifth detection unit 35, it fills step S204 and proceeds to step S205.

The control unit 45a completes the measurement of the drive amount of the transport drive unit 43a that started measurement in step S202 when the step S204 is satisfied. Then, the measured value of the drive amount of the transport drive unit 43a actually required while the front end Saf of the sheet Sa is transported from the installation position of the fourth detection unit 34 to the installation position of the fifth detection unit 35 is acquired.

In step S205, the measured value of the drive amount of the transport drive unit 43a actually required while the acquired front end Saf of the sheet Sa is transported from the installation position of the fourth detection unit 34 to the installation position of the fifth detection unit 35. , The design value of the drive amount of the transfer drive unit 43a stored in advance corresponding to the distance from the fourth detection unit 34 to the fifth detection unit 35 in the transfer path 5 is compared. In step S206, the timing at which the transfer of the sheet Sa is stopped is corrected by the cutter processing unit 22 by using the difference obtained by comparing the measured value and the design value.

Here, in the first embodiment, the reference position on the upstream side of the fifth detection unit 35 in the transfer path 5 used as the measurement start point of the drive amount of the transfer drive unit 43 is the cutting blade 36. The installation position of. This is because, in the processing pattern of the first embodiment shown in FIG. 2, an unnecessary piece of paper Jf is set at the front end portion of the sheet S. The second cutting line K2 forming the rear end Qr of the processed object Q is executed after the cutting process is performed on the first cutting line K1 forming the front end Qf of the processed object Q. In this case, the timing of the cutting process of the first cutting line K1 forming the front end Qf can be used as the reference of the second cutting line K2 forming the rear end Qr.

However, in the processing processing pattern of the second embodiment, an unnecessary piece of paper Jf is not set at the front end portion of the sheet Sa. Therefore, the timing of the immediately preceding cutting process cannot be used as a reference for the cutting process of the first cutting line K1a forming the rear end Qar of the processed product Qa1 set on the most downstream side. Therefore, in the second embodiment, the reference position is set as the installation position of the fourth detection unit 34. From this, even if the processing pattern is such that the sheet Sa is not cut before the cutting process at the first cutting line K1a forming the rear end Qar of the processed object Qa, it is downstream of the processing unit 6. It is possible to control the transport stop timing based on the detection result of the fifth detection unit 35 on the side.

In step S207, the control unit 45a drives the transport drive unit 43a by the corrected remaining drive amount obtained by correcting the remaining drive amount in the design. In step S208, it is determined whether or not the formation position of the cutting line Ka of the sheet Sa has reached the installation position of the cutting blade 36. When the measured value of the drive amount of the transport drive unit 43a reaches a predetermined value which is the remaining drive amount after the correction performed in step S206, step S208 is satisfied. The operation of steps S209 to S211 is the same as that of the first embodiment.

After the formation of the first cutting line K1a, the control unit 45a restarts the driving of the transport drive units 41 to 44a, and restarts the transport of the sheet Sa by the transport unit 4 in the entire device. At this time, the control unit 45a sets the transport speeds of the ninth and tenth transport units 19a and 20a installed on the downstream side of the cutter processing unit 22 to the transport speeds of the seventh and eighth transport units 17a and 18a on the upstream side. The transport drive units 43a and 44a are controlled so as to be faster.

As a result, between the preceding sheet Sa conveyed by the 9th and 10th transfer units 19a and 20a and the subsequent sheet Sa conveyed by the 7th and 8th transfer units 17a and 18a in the transfer path 5a. , There is a difference in transport speed. Then, a space in which the sheet Sa is not conveyed is formed between the preceding sheet Sa and the succeeding sheet Sa. Therefore, the fifth detection unit 35 detects the rear end Sar of the preceding sheet Sa and the front end Saf of the succeeding sheet Sa that have been conveyed to the installation position of the fifth detection unit 35 after the formation of the first cutting line K1a. Is possible. Then, the control unit 45a forms the second cutting line K2a on the subsequent sheet Sa based on the detection result of the fifth detection unit 35, so that the timing at which the transfer is stopped can be controlled.

In the cutting process for forming the second cutting line K2a, the reference position can be set to the position where the fourth detection unit 34 is installed, and instead, the position where the cutting blade 36 is installed in the cutter processing unit 22. Is also possible. When the reference position is the installation position of the 4th detection unit 34, the installation position of the 4th detection unit 34 performed in step S205 when forming the 1st cutting line K1 is used as the reference position to the installation position of the 5th detection unit 35. The difference between the measured value of the drive amount of the transport drive unit 43a required for transporting the seat Sa and the corresponding design value is used to correct the timing at which the seat Sa is stopped.

On the other hand, when the reference position is set to the cutting blade 36 installation position, the control unit 45a has the first cutting line K1a in which the fifth detection unit 35 has become the front end Saf of the sheet Sa from the time of the cutting process forming the first cutting line K1a. The drive of the transfer drive unit 43a stored in advance based on the measured value of the drive amount of the transfer drive unit 43a up to the time when the formation position is detected and the distance from the cutting blade 36 to the fifth detection unit 35 in the transfer path 5a. Compare with the design value of the quantity. Then, the difference between the two is used to correct the timing at which the seat Sa is stopped.

(Third embodiment)
FIG. 7 is a schematic vertical sectional view of the processing apparatus 100b according to the third embodiment. In the first and second embodiments, the most downstream processing unit is composed of the cutter processing unit 22, but in the third embodiment, the sheet Sb intersects the sheet Sb in the transport direction F instead. A crease processing portion 21m for forming a mountain fold line Cb in the direction is provided. In the crease processing section 21m, the folding die 37 composed of the convex die 38 and the concave die 39 of the valley fold crease processing section 21 according to the first and second embodiments is arranged upside down. The crease processing unit 21m is installed below the transport path 5b and has a convex shape 60 having a convex portion at the upper end and a concave shape 59 having a concave portion at the lower end which can be inserted into the convex portion of the convex shape 60. The crease 61 is provided.

The concave type 59 is connected to a folded type drive unit 54 such as a motor via a power transmission mechanism. By lowering the concave type 59 by the driving force of the folding type driving unit 54, the convex parts of the convex type 60 arranged downward facing each other are inserted into the concave portions of the concave type 59 from which the convex parts have been lowered, with the sheet Sb interposed therebetween. , A mountain fold line Cb is formed in the width direction W orthogonal to the transport direction F.

Further, in the third embodiment shown in FIG. 7, the first and second crease processing portions 21 on the upstream side forming the valley fold and the crease processing portion 21m on the downstream side forming the mountain fold are located between the crease processing unit 21 on the upstream side and the crease processing unit 21m on the downstream side forming the mountain fold. The eighth transfer drive unit 18, 18a provided in the embodiment is not provided. In the crease process, the sheet Sb is not separated before and after the transfer direction F, so that the transfer roller can be not provided between the processing processes 6 arranged before and after on the transfer path 5b. Therefore, it is possible to increase the distance between the transport units 17 and 19 arranged in the front-rear direction, such as the seventh transport unit 17b and the ninth transport unit 19.

The 9th transport section 19b on the downstream side of the mountain fold crease processing section 21m shown in FIG. 7 is connected to the transport drive section 43b together with the 7th transport section 17b on the upstream side via a power transmission mechanism, and the transport drive section 43b is connected to the transport drive section 43b. It is rotated by the drive of.

In the third embodiment, the fifth detection unit 35b is configured by an image pickup element such as a CCD camera instead of the light transmission type sensor. Therefore, in addition to the front end Sbf or the rear end Sbr of the sheet Sb, the fifth detection unit 35b includes a mark printed at a predetermined position on the sheet Sb, a polygonal line Cb formed at a predetermined position on the sheet Sb in the processing unit 6b, and chamfering. Processing, perforations, etc. can be detected. The control unit 45b sets the timing at which the processing unit 6b provided on the transfer path 5b stops the transfer by the transfer unit 4b in order to process the sheet Sb at the time of the processing process already performed in the processing unit 6b. Control based on.

Further, since the control unit 45b processes the sheet Sb by any of the valley fold and mountain fold crease processing units 21 and 21 m as the plurality of processing units 6b provided on the transfer path 5b, the transfer unit 4b The timing at which the transport is stopped is controlled based on the processing time point already performed in either the valley fold or mountain fold crease processing unit 21 or 21 m.

Then, the control unit 45b sets the timing at which the transport by the transport unit 4b is stopped in order to form the valley fold fold line Cb on the sheet Sb in the valley fold crease processing unit 21 which is the processing unit 6b on the upstream side at the same valley fold. Control is performed based on at least one of the processing time points of the crease processing unit 21 of the mountain fold or the crease processing unit 21m of the mountain fold which is the processing unit 6b on the downstream side. The control unit 45b sets the timing at which the transport by the transport unit 4b is stopped in order to form the mountain fold fold line Cb on the sheet Sb in the mountain fold crease processing unit 21 m, which is the processing unit 6b on the downstream side, at the same mountain fold crease. Control is performed based on at least one of the processing time points of the processing unit 21m or the valley fold crease processing unit 21 which is the processing processing unit 6b on the upstream side.

FIG. 8 is a plan view showing an example of a processing pattern of the sheet Sb according to the third embodiment. In the processing pattern of the sheet Sb shown in FIG. 8, four cutting lines T parallel to the transport direction F and five folding lines Cb parallel to the width direction W are set. The first, third, and fifth fold lines Cb that are odd-numbered from the downstream side in the transport direction F of the sheet Sb are mountain fold fold lines C1, C3, and C5, and the even-numbered second and fourth fold lines Cb are valley folds. Folded lines C2 and C4. From this, two long processed products Qb are arranged in the transport direction F in which zigzag folding lines C1 to C5 in which mountain folds and valley folds are alternately arranged are formed at equal intervals.

The operation of the third embodiment will be described. The sheet Sb is supplied to the transport path 5b by the supply unit 3, cut by the slitter processing unit 29 along the cutting line T parallel to the transport direction F, and unnecessary paper pieces Jm and Jc are collected by the paper piece collection unit 23.

When forming the first polygonal line C1, the control unit 45b performs correction using the detection result of the fifth detection unit 35 based on the detection result of the fourth detection unit 34, and forms the first polygonal line C1. Determine the stop timing of the transport for. Therefore, when forming the first folding line C1, the control unit 45a determines whether or not the fourth detection unit 34 has detected the front end Sbf of the sheet Sb.

When the fourth detection unit 34 detects the front end Sbf of the sheet Sb, the fourth detection unit 34 measures the drive amount of the transport drive unit 43b from the time when the front end Sbf of the sheet Sb is detected. In the second embodiment, it is subsequently determined in step S203 shown in FIG. 6 whether the next cutting process is a cutting process for forming the rear end Sar of the processed product. However, in the third embodiment, this is determined. Do not make such a judgment.

Then, it is determined whether or not the fifth detection unit 35 has detected the front end Sbf of the sheet Sb. Before the fifth detection unit 35 detects the front end Sbf of the sheet Sb, it is determined whether or not the machining position has been reached without comparing the measured value and the design value.

In the case of the processing pattern shown in FIG. 8, the length Lb1 between the front end Sbf of the sheet Sb and the first folding line Cb1 of the mountain fold is the installation position of the fifth detection unit 35 and the folding of the crease processing unit 21m of the mountain fold. When the distance is shorter than the distance of the installation position of the mold 61, the first folding line C1 forming position reaches the folding mold 61 installation position before the fifth detection unit 35 detects the front end Sbf of the sheet Sb.

In this case, the measured value of the drive amount of the transport drive unit 43b that started measurement when the fourth detection unit 34 detects the front end Sbf of the sheet Sb is the distance between the fourth detection unit 34 and the folding die 61 and the processing processing information. When the design value of the drive amount of the transport drive unit 42b calculated from the above is reached, it is determined that the first folding line C1 which is the processing position has reached the installation position of the folding mold 61.

More specifically, to a predetermined value obtained by adding the length Lb1 from the front end Sbf of the sheet Sb to the first folding line C1 to the distance from the installation position of the fourth detection unit 34 to the installation position of the folding mold 61 in the transport path 5b. When the measured value of the drive amount of the transfer drive unit 43b reaches the design value of the drive amount of the corresponding transfer drive unit 43b, it is determined that the first folding line C1 has reached the installation position of the folding mold 61.

On the other hand, the length Lb1 between the front end Sbf of the sheet Sb and the first folding line C1 of the mountain fold is longer than the distance between the installation position of the fifth detection unit 35 and the installation position of the folding mold 61 of the crease processing unit 21m of the mountain fold. When it is good, after the fifth detection unit 35 detects the front end Sbf of the sheet Sb, the first folding line C1 forming position reaches the folding mold 61 installation position. In this case, when the front end Sbf of the sheet Sb is transported to the installation position of the fifth detection unit 35, the measured value of the drive amount of the transfer drive unit 43b is compared with the design value. The measured value of the drive amount of the transport drive unit 43b when forming the first folding line C1 is that the front end Sbf of the sheet Sb is transported from the installation position of the fourth detection unit 34 to the installation position of the fifth detection unit 35. It is a value of the driving amount of the transport driving part 43b actually required. The design value when forming the first folding line C1 is the design value of the drive amount of the transport drive unit 43b corresponding to the distance from the fourth detection unit 34 to the fifth detection unit 35 in the transport path 5b.

Then, the difference between the measured value and the design value is added or subtracted from the remaining drive amount to correct the timing at which the transfer of the sheet Sb is stopped in the mountain fold crease processing unit 21 m. The transport drive unit 43b is driven by the remaining drive amount after the correction.

When all the remaining driving amount after the correction is driven, the first folding line C1 as the processing processing position reaches the folding mold 61 installation position, and the driving of the transport driving unit 43b is stopped. Then, the drive amount of the transport drive unit 43b is reset, and then the sheet Sb is processed. At that time, the control unit 45b drives the folding drive unit 54. From this, the concave mold 59 is lowered, and the lower convex mold 60 is inserted into the concave mold 59 with the sheet Sb interposed therebetween to form the first folding line C1 of the mountain fold. This completes the processing of the first folding line C1.

FIG. 9 shows a flow related to the operation on the downstream side from the installation position of the fourth detection unit 34 of the transport path 5b when forming the second to fifth folding lines C2 to C5 after forming the first folding line C1. In step S301 of FIG. 9, the drive of the transport drive unit 43b, which had been stopped when the first folding line C1 was formed, is restarted. In step S302, the measurement of the drive amount of the transport drive unit 43b is started.

In step S303, it is determined whether or not the fifth detection unit 35, which is the detection unit 10b on the downstream side of the processing unit 6b, has detected the processing position of the sheet Sb that has already been performed. When the processing apparatus 100b shown in FIG. 7 executes the processing of the processing pattern shown in FIG. 8, when the first folding line C1 is formed, the first folding line C1 of the sheet Sb is formed by the mountain fold crease processing portion 21m. When the fold mold 61 is installed, the transport direction from the predetermined position St of the sheet Sb shown in FIG. 8 located at the fold mold 37 installation position of the valley fold crease processing unit 21 on the upstream side to the second fold line C2. When the length Li of F is shorter than the distance LK between the fifth detection unit 35b and the installation position of the mountain fold folding mold 61, the fifth detection unit 35 has a first before detecting the first folding line C1 of the sheet Sb. 2 The folding line C2 forming position reaches the folding mold 37 installation position. In this case, step S303 is not satisfied and the process proceeds to step S307.

As described above, in the third embodiment, in the valley folding second folding line C2 forming process as the processing process unit 6b provided on the transfer path 5b, the transfer by the transfer unit 4b is stopped in order to process the sheet Sb. The timing is controlled based on the time point at which the first fold line C1 is already formed in the mountain fold crease processing unit 21m as the processing processing unit 6b. Therefore, the second folding line C2 can be properly formed. In particular, by resetting the drive amount of the transport drive unit 43b at the time of the immediately preceding machining process, that is, at the time of forming the first folding line C1b, and starting measuring the drive amount of the transport drive unit 43b thereafter, the accumulation of misalignment can be eliminated. Therefore, the positional deviation in the transport direction F can be further reduced.

On the other hand, it is assumed that the set position of the second folding line C2 is at the position of C22 shown by a rough broken line in FIG. When the first fold line C1 of the sheet Sb is at the installation position of the fold mold 61 of the mountain fold crease processing portion 21 m, the sheet Sb located at the fold mold 37 installation position of the valley fold crease processing portion 21 on the upstream side. The length Lj of the transport direction F from the predetermined position St to the second folding line C22 is longer than the distance between the fifth detection unit 35b and the installation position of the mountain fold folding mold 61. At this time, after the fifth detection unit 35 detects the first folding line C1 of the sheet Sb, the second folding line C2 forming position reaches the folding mold 37 installation position. The timing at which the transfer is stopped to form the second fold line C2 can be controlled based on the processing time of the first fold line C1 already performed in the crease processing section 21 m of the mountain fold on the downstream side. In FIG. 9, when the first folding line C1 forming position is conveyed to the installation position of the fifth detection unit 35, step S303 is satisfied and the process proceeds to step S304.

In step S304, the measured value of the drive amount of the transport drive unit 43b is compared with the design value. The measured value in step S304 when forming the second fold line C2 is actually measured while the first fold line C1 of the sheet Sb is conveyed from the installation position of the mountain fold fold type 61 to the installation position of the fifth detection unit 35. This is the required drive amount of the transport drive unit 43b. The design value when forming the second folding line C2 is the design value of the driving amount of the transport driving unit 43b corresponding to the distance LK from the mountain fold folding mold 61 to the fifth detection unit 35 in the transport path 5b. ..

In step S305, the difference between the measured value and the design value is added or subtracted from the remaining drive amount, and the timing at which the sheet Sb transfer is stopped in the valley fold crease processing unit 21 is corrected. In step S306, the transport drive unit 43b is driven by the remaining drive amount after correction.

In this way, in the valley folding second folding line C1b2 forming process as the processing process unit 6b provided on the transfer path 5b, the timing at which the transfer by the transfer unit 4b is stopped in order to process the sheet Sb is set to another processing. Control is performed based on the processing for forming the first fold line C1 already performed in the mountain fold crease processing unit 21m which is the processing unit 6b. Then, a comparison is made between the measured value of the drive amount of the transport drive unit 43b from the processing for forming the first fold line C1 to the detection of the first fold line C1 by the fifth detection unit 35 and the corresponding design value. Then, the remaining drive amount is corrected. Therefore, the formation position of the second folding line C2 can be made more accurate.

When all the remaining drive amount after the correction is driven, it is determined in step S307 that the second folding line C2 has reached the folding mold 37 installation position of the valley fold crease processing unit 21, and the step 307 is satisfied, and the process proceeds to step 308. move on. In step S308, the drive of the transfer drive unit 43b is stopped, and in step S309, the drive amount of the transfer drive unit 43b is reset. Then, in step S310, the folding type driving unit 49 connected to the convex type 38 of the valley fold crease processing unit 21 is driven, and the convex type 38 descends and is inserted into the concave type 39. A valley fold second fold line C2 is formed on the sheet Sb. This completes the processing of the second folding line C2.

When forming the third to fifth fold lines C3 to C5, when forming the mountain fold fold line Cb on the sheet Sb in the mountain fold crease processing section 21 m which is the processing process section 6b on the downstream side, or when forming the mountain fold fold line Cb on the upstream side valley. When the valley fold line Cb is formed in the crease processing unit 21 of the fold, the timing for stopping the transportation by the transport unit 4 is set to the processing already performed in the same processing unit 6b or another processing unit 6b. It can be controlled based on the processing time point.

In this way, at the valley fold and mountain fold crease processing units 21 and 21m as the plurality of processing units 6b provided on the transfer path 5b, the timing at which the transfer by the transfer unit 4b is stopped in order to process the sheet Sb. Is controlled based on the processing time already performed in the valley fold and mountain fold crease processing units 21 and 21m as one of the processing units 6b, so that the processing can be performed very appropriately and the transport can be performed. The misalignment in the direction F can be reduced.

In each of the above embodiments, the cutter processing unit 22 and the crease processing unit 21, 21m are described as the processing processing units 6 and 6b of the sheet S, but the processing is not limited to this, and the processing processing includes chamfering processing and perforation forming processing. It may be about other processing processes such as. In the case of each of these processing processes, in order to detect a position other than the front end and the rear end of the sheet, as shown in the third embodiment, a mark printed at a predetermined position on the sheet by an image pickup device such as a CCD camera. And each processing position of the sheet will be detected. Further, although the cutting blade 36 cuts the sheet S along the width direction W orthogonal to the transport direction F, the sheet may be cut along a cutting line oblique to the transport direction F.

Further, the processing apparatus 100, 100a, 100b is used as a processing unit 6 or 6b for performing a predetermined processing process on the sheets S, Sa, Sb in a direction intersecting the transport direction F of the sheets S, Sa, Sb. Although the unit 22 and the crease processing units 21 and 21m are provided, only one or more of these processing processing units may be provided, or a plurality of processing units of the same type may be provided together with the other processing units. Often, it may be appropriately combined with other processing treatments such as perforation forming treatment and chamfering treatment. Further, the number of processing units and transport units may be different from that of each of the above embodiments. Further, the arrangement patterns of the sheets S, Sa, and Sb are not limited to those exemplified in FIGS. It is configurable.

Further, although the first to tenth transport units 11 to 20 are composed of a pair of upper and lower transport rollers, a belt may be used instead of the transport rollers. Further, the transport units 4, 4a and 4b are the ninth transport unit 19 as a detection upstream transport unit installed between the processing units 6, 6b on the transport paths 5, 5a and 5b and the detection units 10, 10b. However, a transport unit may not be provided between the processing unit and the detection unit. Further, the transport unit 4 includes the ninth and tenth transport units 19, 20 as the machining downstream side transport portions installed on the transport path 5 on the downstream side of the machining processing section 6, but downstream of the machining processing section. It may be configured to directly discharge the processed material from the processing section to the mounting section without providing a transport section on the side, or may be configured by a transport section composed of one set or three or more sets of transport roller pairs. , A belt may be used instead of the roller.

Whether or not the control units 45, 45a and 45b determine the timing at which the transfer is stopped for processing the sheets S, Sa and Sb based on the detection results of the detection units 10 and 10b is determined on the sheets 10 and 10b. Although the judgment is made according to the processing processing information, the transfer may be stopped based on the detection result on the downstream side of the processing processing unit regardless of the processing processing information.

Further, although the control units 45, 45a and 45b have driven a plurality of transport drive units 41 to 44 in synchronization, they may be individually driven without synchronization. Then, the transfer of the sheets S, Sa, Sb by the transfer units 4, 4a, 4b was started and stopped in the entire device, but the transfer was continued at one place in the device while the transfer was stopped at another place. The transport state may be different for each processing unit.

Further, various processing processing information is automatically set by the user from the operation panel 46 or automatically by reading the barcode M2 by the reading unit 26, but communicates with an external information processing device such as a personal computer. It may be set. Further, the arrangement pattern of the sheet may be stored in a plurality of storage means by manual input from the operation panel in advance, and each pattern may be called by a number or the like and set.

Further, in the first embodiment, when the third cutting line K3 is formed, the timing for stopping the transfer of the sheet S based on the detection result of the fifth detection unit 35 on the downstream side from the installation position of the cutting blade 36 is set. It was decided not to make corrections. This is because when the length Ld from the second cutting line K2 to the third cutting line K3 is shorter than the distance from the installation position of the cutting blade 36 to the installation position of the fifth detection unit 35, the front end Sf of the sheet S This is because the fifth detection unit 35 cannot detect the formation position of the second cutting line K2. Further, what is cut from the sheet S by the cutting process forming the third cutting line K3 is an unnecessary piece Jd collected by the paper piece collecting unit 23 after the cutting process. Therefore, it is not necessary to control the timing at which the transfer by the transfer unit 4 is stopped in order to form the third cutting line K3 based on the detection result of the fifth detection unit 35. However, when the installation position of the detection unit on the downstream side of the processing unit is near the processing unit, the length Ld from the second cutting line K2 to the third cutting line K3 is from the installation position of the cutting blade 36. The distance to the installation position of the fifth detection unit 35 or more can be set. In such a case, even if it is a cutting process that forms the front end of the processed product that separates unnecessary pieces of paper from the sheet, the transfer stop timing is based on the detection result of the detection unit installed on the downstream side of the processing unit if necessary. May be corrected.

Further, the control unit 45 sets the timing at which the transfer by the transfer unit 4 is stopped in order to form the third cutting line K3, based on the time when the second cutting line K2 is formed, which is the time immediately before the processing in the cutter processing unit 22. Although it is controlled, it may be based on another time point as long as it is the time point of the machining process already performed in the machining processing unit. For example, it may be the time of formation of any one of the first cutting line K1, the second cutting line, and the folding line C.

Further, in the second embodiment, the control unit 45a sets the transport speeds of the ninth and tenth transport units 19a and 20a installed on the downstream side of the cutter processing unit 22 to the seventh and eighth transport units on the upstream side. The transport drive units 43a and 44a were controlled so as to be faster than the transport speeds of 17a and 18a. The transport drive unit may be controlled so as to be earlier than the transport start timing of. From this, by setting the transfer start timing of the preceding sheet to be earlier than that of the succeeding sheet, it is possible to form a space in which the sheet is not conveyed between the preceding sheet and the succeeding sheet. The rear and front edges of the sheet can be easily detected.
