JPH05330022A - Cutting estimation control device for web - Google Patents

Abstract

PURPOSE:To modify precisely in a short time not relying on the perception of a worker by providing an input means for inputting the numerical value corresponding to the modifying amount of cutting estimation to be modified and a cutting estimation matching mechanism drive and control means for modifying the cutting estimation based on the input numerical value. CONSTITUTION:The deviation amount between a pattern and the cutting position measured from a printed matter printed as a trial is input in the numerical value, and an input data ID is displayed once and transmitted to an arithmetic circuit 13 by pushing a modification button. The relationship CM=f (ID) between the input data ID considering a mechanism like a compensator roll 48 and the like and the movement amount data CM is stored in the arithmetic circuit 13, and the input data ID is converted to the compensator roll movement amount data CM for modifying the input data. The compensator roll 48 is started based on the compensator roll movement amount CM by a motor 47 through a motor driving circuit 14 by means of the output from the arithmetic circuit 13 to modify the deviation amount between the pattern and the cutting position.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a web cutting register control device for controlling a cutting register of a web which continuously flows in a printing machine or the like.

[0002]

2. Description of the Related Art Conventionally, for example, in a rotary printing machine,
The apparatus shown in FIG. 4 was used to adjust the register between the printing on the web and the subsequent cutting as processing. In this apparatus, the web 42 mounted on the paper feed unit 41 is
Is conveyed to the printing unit 44 via the guide roller group 43. The web 42 that has passed through the printing unit 44 is
It reaches the folder 49 via the dryer 45 and the web path unit 46, where it is cut and discharged. Web pass section 46
Has a compensator roll 48 driven by a motor 47. When the compensator roll 48 is driven, the web length in the conveyance path changes, so that the registration of the pattern and the cutting can be adjusted.

Conventionally, the adjustment of the register of the design and the cutting is performed.
At the start of printing, the operator actually checks the pattern deviation of the printed matter discharged from the folding machine 49 and the cutting register, and pushes the button on the operation panel (not shown) of the cutting register control device so that the pattern comes to a predetermined position. It was done by operating the or dial. Then, once the design and the register of the cutting are adjusted, the control is automatically performed so as to maintain the cutting register by using, for example, the device described in Japanese Patent Laid-Open No. 64-11794.

[0004]

By the way, in the above-described conventional apparatus, the temperature, humidity, ink density, drying temperature, etc. during the initial registration at the start of printing, or during the printing despite the initial registration, etc. Change or the change in paper quality due to the change in the paper quality in the winding of different production lots causes the correction of the cutting register, but the relationship between the correction command signal such as buttons and dials and the cutting register correction amount is clear. Because it was not, I had to rely on the workers to do the work. Therefore, when an inexperienced operator operates it,
There has been a problem that it takes a long time to register the initial trimming and a large amount of waste paper occurs.

The present invention has been made under the circumstances as described above, and an object of the present invention is to provide a web cutting register control apparatus capable of accurately correcting an initial cutting register in a short time. is there.

SUMMARY OF THE INVENTION The present invention relates to a web cutting register control device for controlling a web cutting register that continuously flows in a printing machine or the like, and the above object of the present invention is to provide the cutting register. The input means capable of inputting a numerical value corresponding to the correction amount to be corrected, and the cutting register adjusting mechanism drive control means for correcting the cutting register based on the numerical value input via the input means. It is achieved by providing.

[0007]

In the present invention, the numerical value corresponding to the correction amount of the cutting register to be corrected is input to the input means. The cutting register adjusting mechanism drive control means corrects the cutting register based on the input numerical value.

Embodiments of the present invention will now be described in detail with reference to the drawings. FIG. 1 is a diagram showing the configuration of an embodiment of a web cutting register control device of the present invention. In the present invention, the operation panel 31 and the arithmetic circuit 13 are combined with the device described in JP-A-64-11794.
FIG. 2 is a diagram showing a detailed configuration of the operation panel 31. Further, FIG. 3 is a diagram for explaining the misalignment between the design and the cutting.

Therefore, at the start of printing, the worker does
As shown in (A), the amount of deviation a between the pattern P and the cutting position is measured from the printed matter that has been printed once as a test, and the operation panel 31
A numerical value is input for the deviation amount of the initial cutting register misalignment with the ten keys 32 provided on the. The inputted input data ID is once displayed on the numerical display panel 33 and is sent to the arithmetic circuit 13 when the correction button 34 is pressed. Here, the arithmetic circuit 13 may be configured by an analog circuit, but is preferably configured by using a general single board computer. In particular, by storing the relational expression CM = f (ID) between the input data ID considering the mechanical portion such as the compensator roll 48 and the compensator roll movement amount data CM, the input data sent to the arithmetic circuit 13 is stored. The ID is converted into compensator roll movement amount data CM for correction.
The compensator roll movement amount data CM output from the arithmetic circuit 13 is sent to the motor 47 via the motor drive circuit 14 that drives the compensator roll 48.
The motor 47 moves the compensator roll 48 based on the input compensator roll movement amount CM. By moving the compensator roll 48, the pattern P
When the printing is performed with the deviation amount a of the cutting position corrected and
The printed matter as shown in FIG. 3A is also a printed matter cut at a predetermined cutting position as shown in FIG. After the cutting register has been corrected in this manner, Japanese Patent Laid-Open No. 64-1
By the means described in Japanese Patent No. 1794, the cutting register after the correction is automatically controlled.

[0010]

As described above, according to the web cutting register control apparatus of the present invention, it is possible to accurately correct the initial registration deviation of the design of the printed matter and the cutting in a short time without depending on the operator's perception. ..
