In each printing unit of the rotary machine, control devices make it possible to operate remotely on the maneuvering blocks of the various adjustment members. Similar control devices exist in folding machines and in any auxiliary apparatus associated with the rotary printing machine. All of these control devices are operated from a central station, allowing an operator to introduce appropriate set values into the various regulators. In each printing unit 30, each folding machine 29, and each auxiliary device 28, is incorporated at least one primary station 3 provided to receive the set values coming from the central station 11, 13. Each primary station 3 is connected to the system. at least one application converter on which depends at least one operating block of an adjustment member. Each application converter also receives the instantaneous position values of the operating blocks in order to allow continuous adjustment. Application to rotary printing machines.

Description

The present invention relates to a system for adjusting the parameters of

  operation of a rotary printing machine, comprising a) - adjusting members for each of the operating parameters, b) - actuators for each of the adjusting members, c) - control and adjustment devices for the actuators of the printing units,

  folding machines and auxiliary equipment,

  (d) - and a driving position to introduce the values

deposit.

  With such a system it is possible to set all the important parameters for the operation of the machine and the setting of all important functions

  for quality management, as in particular the

  age in the different colors, the color marks,

  guide marks for the paper web, as well as di-

additional functions.

  It is known to use computers to adjust rotary printing presses, as for example from DE-OS 2 922 964. This document describes a system intended to ensure the preparation and operation of printing presses. printing presses and comprising for this purpose a color processor, a guiding processor, a

  humidification processor and a correction processor.

  These processors produce control signals for

  adjust the color inking, the flow of water, the guideline

  the band, and to ensure any corrections.

  There are known systems for adjusting the operating parameters of a rotary printing machine of the kind in question. These systems may be provided by the applicant under the trade name "WIFAG MARS" as well as by BBC AG of Baden (Switzerland) under the trade name "MPS 2". In these systems, the control members of the quality management functions are generally incorporated as constituent elements of the entire control system of the machine. This system is constituted by a group of programmable memory controller devices, each of which represents a completely independent element, both for hardware and software, forming part of the control system associated with each of the printing units, and the system. set order. These known systems comprise a control station for the introduction of the various setpoints, as well as

  control and / or adjustment devices for

  Positive maneuvering of regulating devices concerning the

  various operating parameters, in the units of im-

  pressure and folding machines, as well as in

  auxiliary auxiliaries; in general, these devices

  control and / or adjustment are constituted by calcula-

programmable memory.

  Thus, for example, each printing unit is associated with a programmable memory calculator. This one plays

  a centralized role in each printing unit, by sending

  cable control signals to control devices that translate quality management functions

  in each corresponding location of the rotary machine of

  primerie, to carry out mechanically an appropriate adjustment

  prayed. To achieve this result, one must first

  each calculator of a large number of connection sockets

  digital or analogue type, and on the other hand

  cepter a set of wiring very abundant and expensive.

  In addition, because of the differences in the length of the lines where the signals pass, it is obligatory to provide an additional adaptation of length for the analog inputs. And the fatigue imposed on computer equipment

  of this system is also very strong.

  On the other hand, such a system poses serious difficulties

  problems with software, because it is necessary to

  see not only the management of 2620380's data and statesor

  various organs, but also the positions of positions of the

to adjustment devices.

  A printing unit is made up of a large number

  mechanical subassemblies ensuring separate functions

  Rees. But if a programmable memory control system is provided for each printing unit, playing a centralized role in this unit, the assembly of all the printing units must be completed completely and the installation of the printing unit completely completed. whole system of

  setting so that it is ready for normal operation-

  before being able to start

  various subassemblies to check that it works properly.

  Thus, one can not perform the adjustment and calibration of the various functions of each subset of such a printing unit, forming part of a rotary machine

  as long as the work has not been completed completely

  the whole installation. Consequently, the commissioning of such a printing unit is a very laborious and expensive operation, and it can generally only be done at the customer's, once complete assembly of all

  of the rotary printing machine.

  The same problems arise when it comes to changing the configuration of a rotary printing machine

  already existing, for example to add a unit of

  additional pressure. This addition of printing units

  additional requirements does not pose any problem of a

  Picnic. But since it is also necessary to ensure the functions of

  quality management on each additional printing unit

  must be connected to the actuators and

  corresponding adjustment units of that unit for calculating

  who plays a centralized role. But the work of cable

  corresponding age is very laborious, and on this subject it is necessary

  consider that such work must be carried out on a machine

  China already installed and which often is also running.

  On the other hand, it quickly becomes apparent that the space available imposes limits as to the capacity and the possibilities of connection. Also in this case, it is not possible to start the additional printing unit and to check its various functions before having completely completed the installation of the adjustment system. Again, as a result, the extension of an already existing rotary printing machine takes a great deal of time and the entire machine or at least some printing units will have to be shut down for as long as possible. the work in question will not have

been completely finished.

  The object of the invention is to provide a system for

  setting of the operating parameters of a rotating machine

  the type of printing mentioned above, as may be done, independently of the entire installation and its general control system,

  in operation, testing and calibration of the various subsystems

  According to the invention, these results are obtained thanks to the fact that:

  - in each printing unit, each machine

  each auxiliary device of the rotating machine

  the printing press is incorporated at least one

  primary post adapted to receive the values of

  generated from the centralized control system;

  - each primary station is connected to at least one

  application weaver which is associated with at least one adjusting actuator; and - each application converter receives values

  of his primary post, as well as

  their snapshots of position of the maneuvering

  of adjustment with which it is associated, the convert-

  application system thus ensuring the adjustment of these

actuators.

  The invention also includes the characteristics

complete rotary.

  Thanks to the clearly separated organization of the adjustment system of each subassembly, each organization corresponding to the subassembly concerned, it is possible to optimally carry out the necessary cabling,

  in particular for the cables to have lengths

  relatively short journeys to serve each

organ.

  So far, the manufacturers of rotary machines

  have obtained the necessary control systems.

  machines for these machines from specialist suppliers

  indicated in each case by the interested customer, that is

  to say by the receiving printer. However, this practice is a problem because each control system provider uses a type of programmable memory control that * * is specific, with a computer hardware of a specific genre and a programming language that is also special. Thus, for each type of machine and for each of the control system suppliers, it is necessary to establish a specific method of development. In particular, it is thus necessary to make multiple adaptations of the sensors and adjusting members incorporated in the machine,

  each in its proper place, to make them correspond-

  to the operating mode of a different control system each time, while the functions to be assured

are always the same.

  Thanks to the invention, this complication is no longer unavoidable, since each proposed primary station is provided with at least one interface for two-way data exchange, in asynchronous mode and in series of bits, such as existing in most control systems of different origins; so you can connect each primary station virtually with any of the posts

  a complex control system. The primary post

  sign of operation provided by the control system and can also in return provide instantaneous values

  realities, by translating them into instantaneous values of

  can be displayed at the machine operator's station. Such an interface makes it easy to connect to

  control system from any supplier the components

  which are "specific to the machine under consideration", in

  particular the control devices and their actuators

  by removing the tedious and, until now, habitual adaptation work of these organs, because of the various

  existing control systems on the market.

  According to a preferred embodiment of the invention, each primary station is connected to a secondary station acting as a sort of "buffer" and provided with a connection socket which allows, independently of the control system, to perform the verification and calibration of the different specific components of the printing machine

  considered. It is thus possible to easily carry out the exten-

  sion of an already existing rotary printing machine without having to accept long periods of unavailability of this machine. Indeed, all new subsets

  have already been "pre-set" and started

  lable, before being put in place at the place of the complete rotary machine. In addition, the maintenance and service work is carried out very rationally on

such materials.

  The same advantages are obtained when it comes to equipping an already existing rotary printing machine, with a view to a more advanced automatic operation, since the system according to the invention makes it possible to exploit return signals emitted by the various specific components of the machine, and we can connect them without difficulty

  to an already existing control system.

  The modular construction system proposed allows

  also a standardization of the control system of

  quality management. In other words, the specific components of the machine in question, that is to say the sensors and the adjusting members, and the organs

  their control, can be connected from

  standard to the circuits of the rotary printing machine

  merie, to connect them to any of the existing control systems on the market, and regardless of the origin of the control system in place on the machine

  in question. We can even achieve a standardization

  machine-specific components, regardless of the type of machine, which allows even more flexibility to build a system from the various

modules available.

  An embodiment of the invention will now be described by way of example, presented hereinafter with reference to the appended drawings, in which:

The rotary printing machine is equipped with a centralized control 11, of a known type, a control station 13, also of a known type, and an external device 12

  are incorporated in the gateway 28 serving the
