As shown in FIG. 7, the transport speed V4 of the unit paper width alignment transport means 46 is faster than the transport speed V1 of the upper transport body 47 and slower than the transport speed V3 of the lower transport body 48. Specifically, the transport speed V4 of the unit paper width aligning transport means 46 is twice the transport speed V1 (27.5 m / min) of the upper transport body 47, and the transport speed V3 (110 m / min) of the lower transport body 48. Is set to 55 m / min.

Since the unit paper width aligning and conveying means 46 only carries the unit paper N on the roller conveyor 53 that is driven to rotate, the unit paper N is sent from the upper and lower transport bodies 47 and 48 at the same speeds V1 and V3. Then, the specified speed V4 is not immediately achieved, and the intervals in the transport direction F of the unit sheets N may be non-uniform. Therefore, between the unit sheet separating and conveying unit 45 and the unit sheet width aligning and conveying unit 46, a tuned conveying roller (tuned conveying unit) 52 that synchronizes the speed of the unit sheet N with the speed of the unit sheet width aligning and conveying unit 46. Is provided. A pair of upper and lower synchronous conveying rollers 52 are provided, and the unit paper N is sandwiched between them and is conveyed at the same speed V4 as the unit paper width aligning and conveying means 46.

It is installed at a position separated by a longer distance L1 of F length L. Further, the skew sensor 40 is disposed above the adhesion region R of the unit paper N in the paper width direction W.

The skew sensor 40 has a function of optically detecting the presence or absence of the unit sheet N, and is electrically connected to the control unit 44 as shown in FIG. Then, the control unit 44 compares the length in the transport direction F of the unit paper N calculated from the detection result of the skew sensor 40 with the actual length L in the transport direction F of the unit paper N, thereby comparing the unit paper N. Judging the skew of

That is, as shown in FIG. 13A, when the length LE of the unit paper N calculated by the input from the skew sensor 40 is substantially the same as the actual length L of the unit paper N, the control is performed. The unit 44 determines that the unit paper N is properly conveyed without being skewed. The actual length L of the unit paper N is input to the bookbinding apparatus 10 in advance by the user, and a set value may be used. Although not shown, the actual length of the unit paper N is detected. For this reason, a value detected by this sensor may be used.

Then, as shown in FIG. 13B, when the unit paper N is skewed and the right end in FIG. 13 is conveyed ahead of the left end, the unit calculated by the input from the skew sensor 40 is used. The length LS of the sheet N is shorter than the actual length L of the unit sheet N by a predetermined amount or more. In such a case, the control unit 44 determines that the unit sheet N is not conveyed properly and is conveyed in a skewed state. In FIG. 13C, the left end portion is conveyed ahead of the right end portion as opposed to FIG. 13B, and in this case, the unit sheet N calculated by the input from the skew sensor 40 is used. Even in such a case where the length LL is longer than the actual length L of the unit paper N by a predetermined amount or more, the control unit 44 determines that the unit paper N is conveyed in a skewed state. To do.

The controller 44 controls the adhesive discharge operation of the adhesive application nozzle 41 based on the detection result of the skew sensor 40. When the control unit 44 determines that the unit paper N is conveyed in a skewed state, the control unit 44 stops the adhesive discharge operation from the adhesive application nozzle 41 and includes the bookbinding including the adhesive application mechanism 14. The processing operation of the entire apparatus 10 is automatically stopped, and an abnormality is notified by a notification means such as a warning sound or a lamp.

[Outline of bookbinding operation]
Since the operation of each means has already been described in detail, the operation of the entire bookbinding apparatus will be briefly described here.

(1) In FIG. 3, the continuous paper P loaded in a folded state on a paper feed stand or the like is sent in the transport direction F at a predetermined speed by the continuous paper transport means 19 having a pin type tractor, as shown in FIG. Further, the line cutting means 20 divides the left and right continuous papers PL and PL into two by the perforation M4 at the center in the width direction.

(2) The continuous papers PL and PL divided into left and right are once suspended in a U-shape downward, and then aligned by the row overlap conveying means 23 in a state where each margin area S protrudes left and right. As shown in FIG. 4, the left and right margin areas S are cut out by the margin area cutting means 22 and sent to the unit sheet cutting means 21 in the next step shown in FIG.

(3) In the unit sheet cutting means 21, the upper and lower continuous sheets in which a plurality of unit sheets are connected in the sheet conveying direction F by the speed difference between the feed rollers 31 and 32 before and after the conveying direction F and the pressing force of the burst roller 33. PL and PL are cut into unit sheets N at the perforation M5. The unit paper N that is vertically overlapped and cut to the left and right is sent to the unit paper separation / conveying mechanism 16 in the next step shown in FIG.

(4) In the unit sheet separating and conveying mechanism 16, the unit sheet separating and conveying means 45 separates the sheets one by one in the conveying direction one by one in the conveying direction, and the unit sheet width aligning and conveying means 46 sets the left and right width. Unnecessary unit sheet elimination mechanism 15 eliminates unnecessary unit sheet N if necessary, and is further fed into adhesive application mechanism 14 shown in FIG.

(5) In FIG. 12, the identification mark B is read by the mark identification sensor 37 on the unit paper N sent to the adhesive application mechanism 14. That is, it is read whether or not the identification mark B exists. The unit sheet N in which the identification mark B is not detected (that is, the uppermost unit sheet N1 in FIG. 2) passes through the adhesive application unit 36 and is conveyed to the next process without being applied with the adhesive. On the other hand, for the unit paper N on which the identification mark B is detected (that is, the second to fifth unit papers N2 to N5 in FIG. 2), a detection signal of the identification mark B is sent to the control unit 44.

Based on the detection signal of the identification mark B, the control unit 44 sends a drive signal to the adhesive discharge nozzle 41 to drive the adhesive discharge nozzle 41, while transporting the cut unit paper N by the transport unit 35. The adhesive H is applied to the adhesive region R of the unit paper N using the adhesive application nozzle 41.

As described above, the identification mark B is provided on the predetermined unit paper N, and the adhesive discharge nozzle 41 of the adhesive application unit 36 is controlled based on the identification by the identification mark B. Even if the necessity of applying the adhesive is not stored in the control device or the like, the drive of the adhesive discharge nozzle 41 of the paste applying means 36 can be accurately controlled. Even when the number of unit sheets N bound to one booklet changes during the process, the adhesive can be appropriately applied to the predetermined unit sheet N.

In the adhesive application mechanism 14, when the unit sheet N is conveyed obliquely by the conveyance unit 35, the skew sensor 40-detects the skew of the unit sheet N being conveyed, and based on the detection result. The controller 44 controls driving of the adhesive discharge nozzle 41. In other words, the skew sensor 40 optically detects the presence / absence of the unit sheet N at a position spaced a predetermined distance upstream from the installation position of the adhesive discharge nozzle 41 and transmits it to the control unit 44. The control unit 44 compares the length in the transport direction F of the unit paper N calculated from the detection result of the skew sensor 40 with the actual length L in the transport direction F of the unit paper N, and the difference between the two is within a predetermined range. If it is, it is determined that the unit paper N is properly conveyed without being skewed.

Then, based on this result, the control unit 44 sends a drive signal to the adhesive discharge nozzle 41 for the unit paper N that requires application of the adhesive according to the detection of the identification mark B by the mark identification sensor 37, and the adhesive. The ejection nozzle 41 is driven to apply the adhesive H to the adhesive region R of the unit paper N using the adhesive application nozzle 41 while transporting the cut unit paper N by the transport unit 35.

Further, the control unit 44, when the length in the transport direction of the unit paper N calculated from the detection result of the skew sensor 40 is shorter than the actual length in the transport direction F of the unit paper N, or If it is longer than the predetermined amount, it is determined that the unit paper N is conveyed in a skewed state. As described above, when the skew feeding of the paper is detected by the skew feeding sensor, the control unit 44 stops the adhesive discharge operation from the adhesive application nozzle 41 and stops the processing operation of the entire apparatus, and an error occurs. Is notified.

As a result, even when the unit paper N is transported in a skewed state by the transport unit 35, the adhesive H protrudes from the adhesive region R of the unit paper N, or the adhesive is applied to the adhesive region R. Adhesive can be applied properly in accordance with the length in the transport direction F of the unit paper N without being applied sufficiently.

The skew sensor 40 detects the presence or absence of the unit sheet N to be transported, and the control unit 44 detects the length of the unit sheet N in the transport direction F calculated from the detection result of the skew sensor 40 and the unit sheet N. Since the skew of the unit sheet N is determined by comparing the actual length in the transport direction F, it is possible to detect the skew of the unit sheet N by using one skew sensor. Therefore, the number of parts can be reduced, and the manufacturing cost can be reduced.

Since the skew sensor 40 is installed at a position separated from the adhesive application nozzle 41 by a predetermined distance, an inappropriate adhesive application operation is performed while determining whether or not the unit paper N is skewed with higher accuracy. Can be minimized. That is, for example, when the skew sensor 40 is installed in the vicinity of the adhesive application nozzle 41, the presence / absence of the skew of the unit paper N conveyed to the installation position of the adhesive application nozzle 41 is more accurately detected. can do. Further, when the distance between the skew feeding sensor 40 and the adhesive application nozzle 41 is a predetermined distance, the start time of the adhesive application operation can be made in time for determining whether the unit paper N is skewed. It becomes.

Further, when the skew sensor 40 is installed at a position separated from the installation position of the adhesive application nozzle 41 by a distance longer than the length L of the sheet conveyance direction, the control unit 44 determines whether or not the unit sheet N is skewed. After that, the adhesive application operation by the adhesive application nozzle 41 can be started. Therefore, the processing operation can be stopped without applying any adhesive to the skewed unit paper N, and the adhesive is applied obliquely to the unit paper N that is transported obliquely, so that the unit paper N can be used. It is no longer necessary to re-print unit paper N as a substitute, and manual post-processing is facilitated.

Furthermore, since the skew sensor 40 is disposed above the adhesion region R of the unit paper N in the paper width direction W, it is possible to detect the skew of the adhesion region R in the unit paper N more accurately.

When the processing operation is stopped because the unit sheet N has been conveyed obliquely, the unit sheet N manually skewed by the user is removed from the conveyance path, and if necessary, the unit sheet N with the skewed unit sheet N is 1 The other unit paper N to be a booklet is also removed from the conveyance path, and the adhesive is applied manually and the unit paper N is bonded together with the adhesive.

As a result, the unit paper N is conveyed obliquely, and the adhesive protrudes from the bonding region R and is applied obliquely, so that the unit paper N itself or a booklet on which the unit paper N is bound cannot be used. Thus, there is no problem of having to print again after disposal. Further, since the adhesive H does not protrude from the edge of the unit paper N, the adhesive H adheres to the inside of the apparatus, and this adhesive is applied to the subsequent unit paper N or other parts inside the apparatus. There is no problem that H is transferred and soiled.

(6) As shown in FIG. 14, the adhesive-applied unit sheets N sent one by one from the adhesive application mechanism 14 are conveyed to the placement unit 59 by the conveying means 58 of the stack bookbinding means 61. In the placement unit 59, the first sheet of unit paper N is inserted below the pressing member 84, and then new unit papers N are sequentially inserted below the unit paper N on the placement unit 59. And stacked. By this lamination, the unit paper N is bonded with an adhesive applied to the predetermined unit paper N, and a booklet is produced.

In this way, by stacking the unit sheets N sequentially from the lower side, adhesion can be promoted by the weight of the unit sheets N already stacked. Further, by providing the pressing member 84, adhesion of the unit paper N can be further promoted.

In order to take out the produced booklet from the placement portion 59, the pressing member 84 is removed, and the booklet at the top is taken out in order from the back. Therefore, the booklet can be taken out even during the bookbinding operation. Further, it can be taken out as a booklet in the order of printing on the continuous paper P.

Then, the control unit 44 compares the length in the transport direction F of the unit paper N calculated from the detection result of the skew sensor 40 with the actual length L in the transport direction F of the unit paper N, thereby comparing the unit paper N. In other methods, for example, a pair of left and right skew sensors installed at the same position in the paper conveyance direction and separated by a predetermined distance in the width direction are installed.
