In the remote control device of the inking unit of the printing press, which has a control system 9 that operates during the adjustment process and a control section consisting of an addition unit H1, the control system 9 is connected to a manual activation unit 13 and a control section consisting of an addition unit H1. Starting from the adjustment system I of the equipment, a sequence control unit 14 that queries the position detection 11!3 and connects the actuator 2, a difference generator 15 that compares the difference between two adjacent adjustment systems, and I
It is formed by an arithmetic unit 16 that calculates the target value of the actuator 2 of the adjustment system connected to Im and the adjustment system connected on both sides.

In the figure, reference numeral 4 indicates a known printing 1i11I production function group, from which a finished print 5 is sent out. Also, code 7
, 8 and 10 are the first . Second. A third line system is shown.

Compensation of the positions of the first and post-moth regulating systems in the surrounding area is carried out by considering the two virtual regulating systems of the two sea breams connected to the outer l111 of the first and last regulating systems, respectively, and these virtual regulating systems are at the zero position. Because of this, the amount of ink in the peripheral area of the ink metering device is reduced. That is, it is influenced by the print result. .

Compensation for the position of the first and last actuation adjustment system is CJI611
(if the area alignment system is excluded from the operation/process) the same as above occurs. But in this case,
The effect of reducing the amount of ink is positively evaluated.

The object of the invention is to provide a remote control device with a simple construction, low manufacturing costs and low operating costs in order to obtain optimum printing results even in peripheral areas.

The problem of the present invention is to create a remote control device with a structure adapted to practical construction requirements, so that a compensation corresponding to the needs can also be carried out in the surrounding area with a single compensation tour. be.

According to the invention, a knife support system with an adjustment system acting on a continuous knife and consisting of an actuator and a position detector and a single 1g! or multiple conversion systems, and 1
A control system, a manually operated activation device, and a sequence operating to match the discontinuous course of the position of the if support system to a continuous function of the neutral line of the knife when a predetermined limit value is exceeded during the 1I firefly process. In the remote control system of the printing press, which consists of 1II11 systems consisting of a control section, a difference generating device, and an arithmetic unit, and an addition unit, the above-mentioned manually operated starting device and sequence control section are connected. The problem of the present invention is solved by arranging a control unit which is connected to the sequence control Ils of one ILI through the storage device on the output side between them.

The present invention will be described below with reference to an embodiment shown in FIG.

In the figure, a control system 9IIi has a manually operated starting device 13, and this manually operated starting device 13 is connected to a sequence control unit 14.
At the input end of the sequence control unit 14, the measured value B is inputted via the second line system 8, and the measured value ^ is inputted via the 117th) 41st line system 7t-. . Also, on the output side, the third line system 1
The regulator is output via 0.

Measured values A and 8 then contain information about the position of the knife support system in the surrounding area. Further, in order to carry out necessary operations, the difference generating device 1 is
5 and the arithmetic unit 16 are established.

According to the invention, a control unit 20 is arranged between the manually operated activation device 13 and the sequence control 14. This control unit is added to the storage device 19 on the output side.
The output of this storage device 19 is guided to the sequence control section 14.

The operation of this control system will be explained below.

The measured values ^ or measured values B are applied via line systems 7, 8 to a control system 9.

This control system 9 has the task of matching the discontinuous course of the position of the knife support system to the continuous function of the middle key of the knife when a certain threshold value is exceeded. This systematic compensation is aimed at reducing positional deviations between the knife and its support system that would cause the knife to dislodge from its support system. Following this, the adjustment values are calculated in the control system 9 for the measured values ^ and 8 according to the given laws. This adjustment value is transmitted to the adjustment system for compensation via the third one-way system IO and the summing unit (11) described in the said patent application, which results in an adjustment of the stimulation of the remote adjustment system.

The control system 9 is tripped by command of a manually operated activation device 13 which is activated manually during the adjustment process. The addition of the field unit is controlled by the command from the manually operated starting device 13. This control unit 20# maintains the memory of the position of the outer adjustment system in the storage device 119 as described below.

3J! According to Example IK, during the operation process, all the control systems are integrated, and the first and last i1m are stored in the storage device 19 as the positions of the virtual control systems 211 connected to the outside of the first and last control systems. ! The position value of one system will be stored.

According to the second embodiment, in the peripheral area, the m** line is excluded from the operation grosses, and the position of the 2M inoperative adjustment system connected to the outside of the middle K, first and last operation adjustment system of the storage device 19 is as follows. Zero value is stored.

Therefore, the sequence control unit 14 starts one cycle in which one of the outermost adjustment systems on both sides runs sequentially to the outermost adjustment system on the opposite side. At that time, 2
Two adjacent measured values A or two adjacent measured values 8 are aligned, the difference between them is formed in a difference generator 15 and later checked for exceeding a specific threshold value. If the threshold is not exceeded, the sequence control unit 14 moves to the next adjacent measurement value At or 8 on both sides. However, if it exceeds the threshold, the key that follows the other @! The measured values ^ or B from the I system are adjusted and processed in the arithmetic unit 16 . The adjustment value obtained in the arithmetic unit 16 is sent from the sequence control unit 14 to the jI30 wire #1 line thread 18 system 10 for correction of the plurality of remote adjustment devices on both sides of the threshold exceeded.
and sent to the corresponding coordination system.

In the case of compensation according to the first embodiment, starting from the first adjustment system, in the first adjustment system and the final adjustment system, since the virtual adjustment system continuing outside has the value of the first adjustment system, , the first adjustment system and the final adjustment system remain in the desired position without a value exceeding the tolerance 1, and in this way the first working adjustment does not result in a decrease in the ink cover in the surrounding area. In the case of compensation according to Example 2 of the system and the final adjustment system, since the non-operation adjustment system located outside has a zero value, a value exceeding the allowable difference appears, and the WJ1 operation wI4 adjustment system and the final adjustment system Since the position of the system will be reduced, color guidance as required will be achieved in the excluded 'fcw@regular system.
