The print defect detection device 6 detects whether there is a defect such as a blank sheet in the printed content, and sends it to the paper take-up device 1 to take it up in a roll shape. ing. Here, a known device can be used as the folding device 2, the paper supply device 3, the printing device 4, the perforation processing device 5, and the printing defect detection device 6.
[0010]
As shown in FIG. 2, the roll core 11 of the paper take-up device 1 is rotatably supported at a predetermined take-up position, and is connected to an appropriate rotational drive source (not shown) so as to be able to be connected and disconnected. The roll core 11 is provided so as to be able to move toward and away from the roll core 11 in a horizontal direction, and always maintains the state of contact with the outermost peripheral surface of the continuous paper 10 in response to an increase in the amount of paper wound around the roll core 11 Thus, the crimping roll 12 moving in the separating direction is provided so as to be free to rotate.
[0011]
Further, when the crimping roll 12 moves in the direction of the roll core 11, it can come into contact with the peripheral surface of the roll core 1, and a pressure-sensitive adhesive (not shown) is attached to the peripheral surface of the roll core 11. ) Is applied, the continuous paper 10 can be bonded to the peripheral surface of the roll core 11 by pressing the continuous paper 10 against the peripheral surface of the roll core 11. Further, a guide roll 13 that is always in a predetermined position with respect to the pressure-bonding roll 12 and moves together with the pressure-bonding roll 12 is provided so as to be free to rotate.
[0012]
Furthermore, a cutting blade 14 for cutting the continuous paper 10 in the vicinity of the pressure-bonding roll 12 is provided so as to be swingable. The cutting blade 14 is also configured to move in the horizontal direction together with the pressure-bonding roll 12. And this cutting blade 14 and the said crimping | compression-bonding roll 12 comprise a switching mechanism, The said crimping | compression-bonding roll 12 is a mechanism in which the continuous paper 10 is adhere | attached on the roll core 11, The said rockable cutting blade 14 is the mechanism. This is a mechanism for cutting continuous paper.
[0013]
The continuous paper 10 is supported by the printing defect detection device 6 so as to be able to swing in the vertical direction. The tension roll 18 and the fixed guide roll 19 to be hooked reach the guide roll 13 respectively. Above and below the roll core 11, an upper transfer roll 20 that leads the continuous paper 10 to the upper transfer path and a lower transfer roll 21 that guides the continuous sheet 10 to the lower transfer path are arranged. An upper transfer path is formed by the upper transfer roll, and a lower transfer path is formed by a plurality of lower transfer rolls including the lower transfer roll 21.
[0014]
In order to guide the continuous paper 10 to the upper transfer path, the guide roll 13 passes the space between the pressure roll 12 and the roll core 11 from below and leads to the upper transfer roll 20, while the continuous paper 10 is transferred to the lower transfer path. In order to guide, the guide roll 13 is guided from above to the lower transfer roll 21 through the space between the crimping roll 12 and the roll core 11. Then, the continuous paper 10 is supplied to the folding device 2 via any one of these paths. Which route is selected is determined depending on whether the print side is the front side or the back side.
[0015]
Then, the usage method of the paper winding apparatus 1 comprised as mentioned above is demonstrated. The continuous paper 10 supplied to the printing device 4 from the original fabric 10a of the continuous paper 10 wound in a roll set in the paper supply device 3 and subjected to predetermined printing is transversal perforated by the perforation processing device 5. In addition, the print defect detection device 6 detects whether there is a defect such as a blank sheet in the print content, and then the dance roll 15, the pair of fixed guide rolls 16, 17, and the tension roll 18. The fixed guide rolls 19 reach the guide rolls 13 respectively.
[0016]
Here, when the continuous paper 10 is guided to the upper transfer path, the guide roll 13 is guided from the lower side to the upper transfer roll 20 through the space between the pressure-bonding roll 12 and the roll core 11, and the plurality of sheets shown in FIG. Then, the sheet is transferred to the folding device 2 via the upper transfer roll, and is folded in a zigzag manner with a horizontal perforation as in the prior art, and the folding operation is performed. If this result is confirmed and the folded state is normal, the continuous paper 10 is moved by moving the pressure-bonding roll 12 toward the roll core 11 and pressing the continuous paper 10 against the peripheral surface of the roll core 11. Is adhered to the peripheral surface of the roll core 11. Then, the continuous paper 10 is cut by the cutting blade 14, the roll core 11 is driven to rotate, and the roll core is processed without interrupting the processing operations in the preceding printing device 4 and perforation processing device 5 for the continuous paper 10. 11, the continuous paper 10 is taken up.
[0017]
Here, if the folding state is abnormal, the processing operation in the preceding stage is stopped, the printing device 4 and the perforation processing device 5 are adjusted, and then the folding device 2 performs the folding again in the same manner as described above. The operation is performed, the result is confirmed, and it is determined and executed whether the winding operation of the continuous paper 10 is performed or the processing operation is stopped and the devices 4 and 5 are readjusted.
[0018]
On the other hand, when the continuous paper 10 is guided to the lower transfer path, it is guided from the guide roll 13 to the lower transfer roll 21 through the space between the pressure-bonding roll 12 and the roll core 11 from the top to the bottom. It is transferred to the folding device 2 via the lower transfer roll. Then, as in the case of the above-described upper transfer path, the result of the folding operation is confirmed, and the subsequent operation is determined and executed according to the folding state.
[0019]
When the winding operation of the continuous paper 10 is started and the winding amount of the roll core 11 increases, the pressure-bonding roll 12 gradually moves to the left side in FIG. When the line moves to the illustrated position, a predetermined amount of continuous paper 10 is wound up, the continuous paper is cut by the cutting blade 4, the roll core 11 and the rotational drive source are separated, and a cylinder mechanism (not shown) is used. The wound continuous paper 10 is moved to the packing position (roll core 11 imaginary line state position in FIG. 1) to perform the packing operation. On the other hand, a new roll core 11 is installed at a predetermined position, the same operation as described above is repeated, and the sheet winding operation is continued without stopping the processing operation at the previous stage.
[0020]
The present invention is not limited to the above-described embodiment, and the transfer path for transferring the continuous paper 10 to the folding device 2 is not limited to the two systems of the upper transfer path and the lower transfer path, but may be one system. The switching mechanism is not limited to the combination of the pressure roller 12 and the cutting blade 14.
