Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a processing apparatus for printing the same material on paper or the like at a constant pitch by a plate cylinder or the like, and processing the printed material at each pitch.

[0002]

2. Description of the Related Art As a specific example of a web processing apparatus in which the same object continues at a constant pitch, there is an apparatus that allows a predetermined number of slips to be copied and copied. This will be described. FIG. 3 shows a gluing device for gluing and copying a 3-slip slip. The slips 1a, 1b, 1c are printed and wound on the take-up rolls 2a, 2b, 2c. The slips are unwound and first the slip of 1b is glued to the slip of 1a, and then the slips of 1c Paste the slip.

The sprocket 3 is opened at equal intervals on both sides of the voucher, and its teeth are inserted in the openings to prevent slipping and the voucher is accurately unwound. To attach the slip 1 to the slip 1, the paste on the ship 6 is scooped up by the paste car 5, the paste of the paste car 5 is transferred to the transfer car 4, and the slip 1 is glued. The slip 1b thus pasted and the non-pasted slip 1a are first adhered, and the slip 1c pasted to the slips 1a + 1b
Are glued together to obtain a 3-slip slip.

FIG. 5 is a diagram showing the relationship between the slip 1 and the transfer wheel 4. The slip 1 has perforations indicated by broken lines for each repeat length (pitch where the same one is represented), and the perforation is performed in the range excluding the perforations. For this reason, a part of the circumference of the transfer wheel 4 is missing, and this range is not struck. The center of this missing part should be aligned with the perforation. Therefore, one rotation of the transfer wheel 4 needs to be matched to the slip size, and the transport roll 7 is
Every time the slip size is conveyed, the transfer wheel 4 makes one rotation,
It is necessary to adjust the gear ratio of the gears 8 and 9 driven by the motor 10. That is, the gear ratio of the transfer wheel 4 and the gears 8 and 9 is changed every time the slip size changes.

FIG. 4 is a diagram showing an apparatus for performing the lapping with the nozzle 11, and the same reference numerals as those in FIG. 3 represent the same functions. Nozzle 11
The glue is pumped from the glue tank 14 to the controller 13
The nozzle 11 is opened and closed by the ON and OFF signals from the above to attach the glue to the slip 1. Controller 13 is encoder 12
In order to output the ON and OFF signals in response to the above signal, the encoder 12 makes one rotation while one slip passes the position of the nozzle 11. Therefore, the gear ratio of the gears 8 and 9 is changed every time the size of the slip is changed.

FIG. 6 shows a timing chart when the nozzle 11 performs the sizing shown in FIG. The Z phase and the A phase are outputs of the encoder 12, the Z phase is a pulse output for each rotation of the encoder, and the A phase is a P1 pulse output for one rotation. The nozzle control signal is a signal for opening and closing the nozzle 11 to discharge and block the glue. The OFF signal needs to be output so that the perforations are centered, and for this purpose, the Z-phase pulse must be output in conformity with the slip size. Therefore, each time the slip size is changed, the gear 8,
You have to change the 9 gear ratio.

[0007]

As described above, the gear ratio of the transfer wheel 4 and the gears 8 and 9 must be changed every time the size of the slip is changed. This modification work requires a certain amount of expertise and experience, and also requires such an operator.

The present invention has been made in view of the above-mentioned problems, and provides a processing apparatus which does not require a hardware change even if the constant pitch of webs of the same object continuing at a constant pitch is changed. With the goal.

[0009]

In order to achieve the above object, the web makes one rotation when running for a predetermined length L1 and a Z phase that generates one pulse and an A phase that generates P1 pulses each time. When the same generator appears continuously at the L2 pitch on the web and the pulse generator that has the pulse generator and the counter that counts the pulses generated by the pulse generator, the counter counts the number of pulses of P1 × L2 / L1. A counter setting device for setting the counter so as to output an L2 pitch length signal each time, and processing instruction means for instructing execution of a predetermined processing within a predetermined range of each pitch length of the web based on the L2 pitch length signal. It is equipped with.

Further, when the counter counts the number of counts of the A phase between two consecutive pulses of the Z phase different from P1, the count value is corrected to P1.

[0011]

When the web is running L1 one revolution, a pulse generator for generating Z-phase which outputs one pulse and one A-phase pulse which outputs P1 pulse per revolution is provided on the same web with L2 pitch. When operating, the pulse of this pulse generator is counted by a counter, and one L2 pitch length signal is output every time P1 × L2 / L1 pulses are counted. This is the same as when a pulse generator having a Z phase that rotates to generate one pulse is provided. Therefore, when the pitch L1 is changed to x, if the counter setter generates one pulse each time the counter counts P1 × x / L1 pulses, this is treated as a pulse corresponding to the Z phase. be able to. Based on the pulse corresponding to the Z phase, it is possible to perform a predetermined process on a predetermined range of each pitch length of the web.

Further, when noise comes in while counting the number of A-phase pulses, the counter counts this noise as pulses. Therefore, since the pulse generator makes one rotation, that is, the number of A-phase pulses during the time when the Z-phase pulse is output and the next Z-phase pulse is generated is P1 if there is no noise,
It is monitored whether the A-phase pulses are always counted as P1 pulses between the Z-phase pulses, and when they are different from the P1 pulses, the count value is corrected to P1 pulses to count the influence of noise. Can be eliminated.

[0013]

Embodiments of the present invention will be described below with reference to the drawings. The device for realizing the present embodiment is assumed to be a lapping device for lapping a slip with the nozzle shown in FIG. In this embodiment, the gear 8c. The gear ratio of 9c remains constant even if the size of the slip changes.

FIG. 1 is a diagram showing the configuration of the controller 13 shown in FIG. The nozzle 11 and rotary encoder 12 are shown in Fig. 4.
It is shown in. In FIG. 4, the rotary encoder 12 makes one rotation when the conveyance roll 7 conveys the slip 1 by 254 mm (10 inches), and 1200 pulses are generated for the A phase and B phase, and 1 pulse is generated for the Z phase pulse. When the B phase is forwardly rotated with respect to the A phase, the phase is advanced by 90 degrees, for example. In this way, the B-phase lags the A-phase by 90 degrees in the reverse rotation. This makes it possible to detect the forward and reverse rotation directions.

The CPU 20 performs setting such as setting of a lapping position when the size of the slip is changed, calculation of a correction value of the output of the rotary encoder 12 and correction processing when noise is mixed in the pulse of the rotary encoder 12. Data latch
Reference numeral 21 stores the count number calculated by the CPU 20 according to the slip size, and the first counter 23 counts the pulses of the rotary encoder 12. The comparator 22 outputs a coincidence signal Z0 when the count value of the first counter 23 coincides with the value stored in the data latch 21. The coincidence signal Z0 resets the count values of the first counter 23 and the second counter 26 to zero.

The ON data latch 24 stores the number of pulses indicating the lapping position which is moved by a predetermined number of pulses with the joint position of the slip as a reference (that is, the Z-phase start position). The second counter 26 is the phase A (or B) of the rotary encoder 12.
The ON comparator 25 outputs a coincidence signal and outputs it to the C terminal of the flip-flop 29 when the counted value coincides with the stored value of the ON data latch 24.

The OFF data latch 27 stores the number of pulses indicating a position before a predetermined pulse based on the seam position of the slip. The OFF comparator 28 outputs a match signal to the reset terminal R of the flip-flop 29 when the count value of the second counter matches the value stored in the OFF data latch 27.

The flip-flop 29 outputs 1 from the Q terminal when input to the C terminal and outputs 0 from the Q terminal when input to the R terminal. When the driver 30 inputs 1, the nozzle
Nozzle 11 is closed when 11 is opened and paste is discharged and 0 is input.

Next, the operation when the slip size is changed will be described. As the slip size, for example, a slip of 304.8 mm (12 inches) is input. In this case the CPU
20 sets the value of 1200 × 304.8 / 254 = 1440 pulse / slip size in the data latch 21.

The first counter 23 increments the number of pulses from the A phase and B phase of the rotary encoder 12 in the forward rotation direction,
If it is in the reverse direction, subtraction is performed. It should be noted that since the slip advances in one direction and is pasted, the following description will be made assuming that the slip is added. The comparator 22 constantly compares the value of the data latch 21 with the count value and monitors whether they match.

When the count value of the first counter 23 reaches 1440, the comparator 22 outputs the coincidence signal Z0, and the first counter 23
And the second counter 26 is reset. As a result, the first counter 23 and the second counter 26 set the count value to 0 and start counting again. This is exactly the same as rotating once at 304.8 mm and rotating the rotary encoder with 1440 output pulses synchronously. As a result, the gears 8c and 9c in FIG.
It corresponds to the change of the slip size without changing the gear ratio of.

In the ON data latch 24, for example, from the seam position of the slip (the position where the coincidence signal Z0 is issued in this case),
50 is set if the paste is applied from the 50th pulse, and 1390 is set in the OFF data latch 27 if the paste is interrupted at the 1440-50th pulse.

The ON comparator 25 outputs a coincidence signal to the C terminal of the flip-flop 29 when the count value of the second counter 26 reaches 50, and the OFF comparator 28 outputs a coincidence signal to the reset terminal R when it reaches 1390. Flip-flop 29
Is a JK-FF, but since the J terminal and the inverted output side of Q are connected, it is set when a match signal is input from the C terminal and outputs 1 from the Q terminal, and a match signal is output to the R terminal. When input, it is reset and the Q terminal outputs 0. driver
In the case of 30, when 1 is input, the nozzle 11 is opened to discharge the glue, and when 0 is input, the nozzle 1 is closed and the glue is cut off.

FIG. 2 is a timing chart showing the relationship between the rotary encoder 12, the Z-phase pulse, and the Z0 pulse changed according to the slip size. The Z pulse is output every 1200 pulses per rotation, which is the basic performance of the rotary encoder 12, and the Z0 pulse is output every 1440 pulses. As a result, it is possible to change the encoder according to the slip size by using the same device in terms of hardware.

Next, the noise resistance performance of this embodiment will be described. In FIG. 1, the Z pulse of the Z phase of the rotary encoder 12 is input to the CPU 20 as an interrupt signal. CP
U20 monitors whether the count value of the first counter 23 is 1200 from the input of this Z pulse to the input of the next Z pulse. When noise enters the rotary encoder 12 and outputs it as a pulse, the first counter 23 also counts it. Therefore, the count value of the A-phase (or B-phase) pulse between Z pulses becomes a value different from 1200. When this happens, the CPU 20 corrects the count value of the first counter 23 to 1200 and continues counting. The second counter 26 also counts this noise, but since the first counter 23 is modified, the reset signal Z0 is also a modified signal. Since the second counter 26 is reset by this signal, the influence of noise is exerted only at the time of counting at that time, and does not spread to the subsequent counting.

In this embodiment, the description has been given to the paste on the slip, but it is obvious that the present invention can be applied to processing other than the paste.

[0027]

As is apparent from the above description, according to the present invention, in the case where the same product is processed on a continuous web at a constant pitch, even if the size of the constant pitch is changed, the hardware device can be processed by software. Can be processed without changing. Further, even when noise is included, this effect can be eliminated.
