Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an alignment device for an ink loading remote control system of a printing press having a plate scanner.

(Prior Art) Using an inking device remote control system and a plate scanner,
Printing machines from various manufacturers are known.

Ink supply remote control system Adjustment device for adjusting the position (adjustment and correction) of the density range adjustment screw of the printing machine ink metering system Storage and output unit for adjustment values of the density range adjustment screw It is composed of.

The plate scanner is equipped with a device for detecting the face value of a printing plate, a single or multiple conversion unit for converting the scanner value into a set value of the inking device remote control system, and a selection/conversion unit for the conversion algorithm.
It consists of a storage section. The plate scanner determines the settings of the ink metering system. This includes adjusting the position of the density range adjusting screw and adjusting the ink metering system by scanning the printing plate. The measured value is based on the number and distance of concentration range adjustment screws,
[Built-in] according to printing machine data such as plate size, printing start, etc.] is spoofed by the printer. As a result of the calculation, the so-called surface area (ratio of the surface to be printed) of the plate per density range adjustment screw is obtained.

These values approximately represent the ink demand of J.
In particular, due to the rheological properties of printing ink, there is no proportional relationship between the density range gap and the ink volume, so the disadvantage is that the set value for the mlv range adjustment screw and ink dispensing system is not displayed. . As a result, it is necessary to further improve the appearance of the setting device for the density range adjustment and ink tone system. This conversion depends on printing conditions such as printing in, wetting agent, paper, etc. Therefore, it is very difficult to create an accurate paraplegia algorithm, especially to adapt it to the special printing strip f1. However, the quality of the conversion algorithm is i
1 degree range adjustment and in-4 - Determines the setting quality of the metering system 1 and thus the time savings in adjustment time by the plate scanner and ultimately the efficiency of the plate scanner.

A normal plate scanner has the following a and b regarding the above conversion 0.

It has the characteristics of C.

a) Fixed conversion b) Fixed program conversion -3 = C) Selectable conversion These systems cannot accommodate printing strips f1 or extreme printing conditions, or the choice of conversion method depends on the knowledge and ability of the printing operator. The disadvantage is that it is dependent and therefore not objective.

(Problems that the invention solves and improves) This invention aims to improve the efficiency of printing presses by 17 degrees, and improves printing press ink device remote control system. It is an object of the present invention to provide an alignment device that objectively converts into a range adjustment screw and an adjustment bay for an ink adjustment and lifting device.

In FIG. 1, a sizing printing cabinet 1 has a remote-controlled ink metering system 2 to its right. This system has a plurality of density range adjusting screws 3, an attached density range servo motor 18, a density range button 3 meter 19, an ink transfer roller 20, a novo motor 21, and a potentiometer 22. il
! The area adjustment screw 3 is operated by an adjustment device 5 from an inking device remote control system 4. A storage/output unit 6 belonging to the inking unit remote control system 4 as part of the matching system 12 stores the set values in the event of a work interruption or a repeat command. The storage section of the storage/output section 6 is composed of a well-known mass storage device such as a magnetic tape, a magnetic card, or a floppy disk, and the output section is composed of a well-known interface such as a serial interface. The storage/output unit 6 is connected directly via an adjustment value line 10 to a feedback unit 7 and, together with the feedback unit 7, via a set value line 11 to a second conversion unit 14 of the form scanner 9.

The feedback unit 7 has an input unit 13 on the input side, and an output side is connected to the second conversion unit 14 via a feedback value line 15.

, which monitors and controls the functions of the target value memory 27 and the detected value memory 28, and is connected to the input section 13.

The operation of the 'JA'fl of the present invention will be explained below.

Plate skiing 11 no 91 Ink metering system 2 for printing press 1
This set value is adjusted by the density range servo motor 19 or printer 21 with the density range adjustment screw 3 or ink transfer roller 20.To determine the set value, the plate scanner 9 The value detection unit 17 is well-known in
Measure the printing plate. The obtained measurement value is the first
Conversion is performed by the conversion unit 16. This change section relates the measuring point to machine conditions such as the distance and position of the a If area adjustment screw 3 and the dimensions of the printing plate. The second converter 14 then adapts these values to given printing conditions such as printing ink, wetting agent, paper, etc. Since the printed strips 141 have different values, the algorithm of the second converter 14 must be adjustable.

This adjustment is performed by the selection/storage unit 8. This selection/storage section 8
must be adjusted by the operator based on experimental or empirical values. The second conversion unit 141 outputs the set value 11 to the feedback unit 7 and the storage/output unit 6 that store the set value 11. The setting value 11 of the storage/output unit 6 triggers the setting of the ink metering system 2 via the ink supply remote control system 4 .

During continuous printing, the setting value 11 is corrected by the adjusting device @5 of the inking device remote control system 4.

This supplement iF-11 is necessary because it is compatible with the printing strip f1, and must be taken into account in the conversion algorithm determined by the second converter 14 thereafter.

This role is performed by the feed batter part 7 as part of the alignment system 12. If the calibration paper is present or the command is completed, the adjustment value 10 of the in-1 metering system 2, which is represented by the Ii1 degree potentiometer 19 or the bodensimeter 22, is
is transmitted from the storage/output section 6 of the inking device remote control system 4 to the feedback section 7 via the input section 13 . In the feedback section 7, a feedback value is determined from the settings stored in the target value register 27 and the respective adjustment values from the adjustment value line 10, and the conversion is carried out via the feedback value line 15 in the second adjustment section 14. Correct the algorithm. Naturally, the original conversion algorithm can then be completely changed, or the feedback section can even act as a self-learning device, constantly comparing the set value, adjustment value and feedback value. The feedback unit 7 further smoothes the values in order to divide random values and extreme values by tJI.

By operating the input section 13 of the feedback section 7, calculation of a new feedback value is started for the conversion algorithm. The set value reaches the target value memory 27 via the control device 29 from the first changeover switch 23 and the first storage circuit 25 for memory organization.

After the end of the process, the target value memory 4 contains all the setting values of the density range adjusting screw and the ink transfer roller of the printing press. Once the final adjustment value is obtained, this adjustment value is similarly transmitted to the detected value memory 28. Next, a feedback value is obtained by comparing the set value and the adjusted value using the control station 29 in the performance device 30, and the algorithm is changed.

Technically speaking, in the case of actual IM, target value memory 27, memory 28
, and a first storage circuit 25 and a second storage circuit 26 in the memory.
is used to distinguish and form address ranges.

Conversion can also be performed automatically during continuous printing.
