Description

  The present invention relates to a perforation processing apparatus that performs perforation processing on processed paper.

2. Description of the Related Art Conventionally, in a processing apparatus, a sewing machine cylinder and a receiving cylinder are rotated, and when the perforation is machined, the rotation of the sewing machine cylinder and the receiving cylinder is made differential to synchronize the sewing machine blade of the sewing machine cylinder and the receiving part of the receiving cylinder.

The sewing machine drum rotation speed detector 21d is, for example, a rotary encoder. The sewing machine drum rotation speed detection unit 21 d outputs detection information to the control unit 30. The control unit 30 determines the rotation speed of the sewing machine drum 21 based on the sewing machine drum rotation speed detection unit 21d.

The arm mechanism section 22 has a sewing machine between a contact position Q (see FIG. 4B) where the sewing blade 21a contacts the processing paper 2 and a retraction position R where the sewing blade 21a retracts from the processing paper 2. This is a mechanism for moving the barrel 21 in the vertical direction Z. In each figure, the contact position Q and the retracted position R are indicated by the height of the central axis of the sewing machine drum 21.

The control unit 30 is a control device for comprehensively controlling the perforation machining of the perforation machining apparatus 10, and includes, for example, a CPU (central processing unit).
Details of the processing of the control unit 30 will be described later.

Next, the operation of the perforation processing apparatus 10 will be described.
FIG. 3 is a flowchart showing the operation of the perforation processing apparatus 10 of the present embodiment.
FIG. 4 is a diagram illustrating the operation of the perforation processing apparatus 10 of the present embodiment.
First, in step S (hereinafter referred to as “S”) 1, an operator loads the processing paper 2 into the paper processing apparatus 1, sets the number of processing copies from an input unit (not shown), and processes the paper processing apparatus 1. When a start switch (not shown) is operated, the control unit 30 starts a series of processes.
As shown in FIG. 4B, the sewing machine drum 21 is disposed at the retracted position R in the start state of the processing.

In step S <b> 2, when the processed paper 2 is sent to the perforation processing apparatus 10 by the feed roller 3, the processed paper feed speed detection unit 11 detects the feed speed of the processed paper 2 and outputs a detection signal to the control unit 30. .
In S <b> 2, the control unit 30 makes the outer peripheral speeds of the sewing machine cylinder 21 and the receiving cylinder 23 (hereinafter referred to as “peripheral speed”) the same as the feed speed of the processed paper 2 based on the detection signal of the processed paper feed speed detecting unit 11. Thus, the sewing machine drum drive motor 21b and the receiving drum drive motor 23a are controlled.

  In this way, the perforation processing device 10 controls the rotational speed of the perforation cylinder 21 in a state where the perforation cylinder 21 is disposed at the retracted position R. Damage can be prevented. Further, since the perforation processing apparatus 10 matches the feed speed of the processed paper 2 with the peripheral speed of the outer periphery of the receiving drum 23, damage to the processed paper 2 due to rubbing of the processed paper 2 and the receiving drum 23 can be prevented. .

  In S4, the control unit 30 determines whether or not the processing code portion 2a of the processing paper 2 has reached the detection position by determining whether or not the processing code detection unit 12 has read the processing code portion 2a of the processing paper 2. Determine. When it is determined that the processing code portion 2a has reached the detection position (S4: YES), the control unit 30 proceeds to S5, and when it is determined that the processing code portion 2a has not reached the detection position. (S4: NO), the process from S2 is repeated.

By repeating the processing from S2, it is maintained that the peripheral speed of the sewing machine cylinder 21 and the feed speed of the processed paper 2 are the same until the processed code portion 2a reaches the detection position. . In addition, the control unit 30 continuously performs control for adjusting the peripheral speed of the sewing machine cylinder 21 to the feed speed of the processing paper 2 in processes other than S5 to S8 described later. For this reason, as long as the processing of the processed paper 2 is repeatedly performed, the peripheral speed of the sewing drum 21 is maintained in the same state as the feed speed of the processed paper 2 at normal times other than S5 to S8.
Similarly, the control unit 30 always continues the control for adjusting the peripheral speed of the receiving drum 23 to the feed speed of the processed paper 2. That is, the peripheral speed of the receiving drum 23 is maintained in the same state as the feed speed of the processed paper 2.

In S5, the control unit 30 detects that the machining code detection unit 12 has detected the machining code unit 2a (S4: YES), and based on the output information of the sewing machine blade position detection unit 21c, the rotational position of the sewing machine blade 21a. Determine.
In S6, the control unit 30 determines the perforated machining scheduled position P based on the machining code portion 2a read in S4. The control unit 30 defines the perforation scheduled processing position P with reference to the end portion of the left side X1 of the processing code portion 2a (see FIG. 2). The control unit 30 calculates the amount of movement of the processing paper 2 based on the output of the processing paper feed speed detection unit 11 after the end of the processing code unit 2a has passed through the processing code detection unit 12, thereby creating a perforation. It can be determined which position the planned processing position P is moving.
Then, the control unit 30 controls the rotation of the sewing drum 21 so that the rotational position of the sewing blade 21 a is synchronized with the perforation scheduled processing position P of the processing paper 2. That is, when the perforation processing scheduled position P of the processing sheet 2 reaches the processing place U, the control unit 30 moves the perforation blade 21a to the processing place U (see the lowest point E shown in FIG. 4B). Control to pass through.
Here, it is assumed that the control unit 30 returns to the same peripheral speed as the feed speed of the processed paper 2 in the subsequent perforation processing while the perforation cylinder 21 is located at the retreat position R. The rotation of the perforation cylinder 21 is controlled so that the position of the perforation blade 21a and the scheduled perforation machining position P are synchronized during perforation machining.

As shown in FIG. 4B, specifically, the control unit 30 determines the distance between the processing place U and the detection position of the processing code detection unit 12, the length of the outer periphery of the sewing machine cylinder 21, and the sewing blade 21a. Based on the position, the moving position of the perforation scheduled processing position P, the rotational speed of the perforation cylinder 21, and the feed speed of the processing paper 2, the arrival time of the perforated processing scheduled position P at the processing place U is calculated. Then, the control unit 30 controls the perforation cylinder drive motor 21b so as to accelerate or decelerate the perforation cylinder 21 so that the perforation blade 21a and the perforation machining scheduled position P are synchronized during perforation machining.
In this way, the control unit 30 must be controlled with high accuracy only the rotational speed of the sewing machine drum 21, and can be expected to improve machining accuracy by reducing the number of control targets.

As described above, the peripheral speed of the sewing machine cylinder 21 is normally controlled to match the feed speed of the processed paper 2 as described above. For this reason, the control to synchronize the sewing blade 21a with the perforation scheduled position P can be performed without applying a large rotational force (rotational torque) to the sewing machine drum 21, and the processing time can be shortened. For this reason, the perforation processing apparatus 10 can perform high-speed perforation at a low cost.
On the other hand, unlike the embodiment, when the control is performed from a state where the sewing machine cylinder is stopped, a motor having a large rotational force is required to rotate the sewing machine cylinder from the stopped state, which is expensive. Become. Furthermore, in this case, the processing time for obtaining synchronization increases, and it is not suitable for high-speed machining.

In S7, the control unit 30 determines whether or not the rotational position of the sewing blade 21a and the perforation scheduled processing position P are synchronized.
When it is determined that both are synchronized (S7: YES), the control unit 30 proceeds to S8. On the other hand, when it is determined that both are not synchronized (S7: NO), the processing from S5 is performed. repeat.
In S <b> 8, the control unit 30 controls again so that the peripheral speed of the sewing drum 21 is the same as the feed speed of the processed paper 2.

In S9, as shown in FIG. 4B, the control unit 30 outputs a drive signal to the pneumatic valve 22c based on the time when the perforation scheduled processing position P reaches the processing place U, and outputs the arm mechanism unit. 22 is driven (see arrow C), and the sewing machine drum 21 is moved from the retracted position R to the contact position Q.
For example, the control unit 30 moves the sewing machine drum 21 to the contact position Q immediately after the sewing blade 21a passes the lowest point E of the sewing machine drum 21.
That is, the control unit 30 drives the arm mechanism unit 22 when the distance L3 from the processing place U where the perforation processing is performed to the perforation scheduled processing position P becomes smaller than the circumferential length of the perforation body 21. Then, the sewing machine drum 21 is arranged from the retracted position R to the contact position Q.
Thereby, since the perforation processing apparatus 10 can prevent the perforation blade 21a from coming into contact with a portion other than the scheduled perforation position P of the processed paper 2, the processed paper 2 can be prevented from being damaged. Further, the perforation processing apparatus 10 may drive the perforation cylinder 21 from the retracted position R to the contact position Q within the time until the perforation machine rotates once. Since it can be made longer, control is easy.
Further, since the sewing machine cylinder 21 rotates at the same peripheral speed as the feed speed of the processed paper 2, it is disposed at the contact position Q and gives an extra load to the processed paper 2 even if it contacts the processed paper 2. Absent. For this reason, the perforation processing apparatus 10 can prevent the processed paper 2 from being damaged.

In S <b> 10, as shown in FIG. 4C, the perforation blade 21 a passes through the perforation scheduled processing position P of the processing paper 2 to perform perforation at the perforation scheduled processing position P.
In S11, as shown in FIG. 4D, when the perforation processing on the processed paper 2 is completed, the control unit 30 drives the arm mechanism unit 22 to move the perforation cylinder 21 from the contact position Q to the retracted position. Evacuate to R. At this time, the control unit 30 moves the sewing machine drum 21 to the retracted position R immediately after the sewing blade 21a passes the machining location U.
That is, the control unit 30 performs the arm mechanism before the distance L4 from the processing execution place U to the position after the perforation processing of the processed paper becomes longer than the perimeter of the perforation cylinder 21 after the perforation processing. The part 22 is driven to place the sewing machine cylinder 21 from the contact position Q to the retracted position R.
Thereby, since the perforation processing apparatus 10 can prevent the perforation blade 21a from coming into contact with the portion other than the planned perforation processing position P in the processed paper 2 as in S9, the processed paper 2 is prevented from being damaged. it can. Further, since the perforation processing apparatus 10 can take the timing for driving the perforation cylinder 21, the control is easy.

In S12, the control unit 30 determines whether or not the processing for the set number of copies has been completed. When it is determined that the processing for the set number of copies has been completed (S12: YES), the control unit 30 proceeds to S13, ends the series of processes, and determines that the processing for the set number of copies has not been completed. (S12: NO), the processing from S2 is repeated, and the next booklet is processed.
Since the perforation processing apparatus 10 performs perforation processing based on the new processing code portion 2a in the repeated processing from S2, even if the perforation processing scheduled position P differs for each processing paper, it is appropriate. Perforation can be processed at any position.

  As described above, the perforation processing apparatus 10 of the present embodiment can perform perforation with high accuracy without damaging the processed paper 2.
