Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to several components, in particular a printing unit, a paper feeder, a paper ejection device, as well as a printing machine installed independently of these components. relates to a printing press having a device connected by several electrical conductors for controlling and/or monitoring the printing press.

[Conventional technology]

For printing presses, it is generally known to provide, for example for controlling and monitoring the ink supply, a control desk which is installed in the vicinity of the printing press and is connected to it by several conductors. Thus, for example, according to DE-AS 2 728 738, printing presses are known which are provided with a monitoring desk, or with a control stand or other peripherals, which are connected directly or indirectly to the printing press by conductors. In addition to ink control, this control stand also uses Heidelberg's example (HeidelbergerDruckmas)
Heidelberger Na of chinen AG
Registration can also be carried out in the individual printing units, as is known from Schrichten 3/40).

When installing a press with a control stand or monitoring desk, the wiring between the press and the control stand must be adapted to the local conditions and the output signal conductors of the control stand and the press The input signal conductors of each printing unit or other component, as well as the reverse input/output, need to be matched in location. Even if this wiring work is carried out by a person with appropriate skills, if there are a large number of electrical conductors, they may be connected incorrectly, which may cause problems when starting the printing press. In some cases, it may take time to search for a defective location.

[Problem that the invention seeks to solve]

It is therefore an object of the present invention to provide a wiring between a printing press and a device for its control and/or monitoring that is of such a construction that it is possible to reliably assemble the machine in a short time. It's about doing.

[Means for solving problems]

The purpose of this is to provide electrical conductors with connection points using plug connectors, each of which can be connected and disconnected at only one point between the outlet point of the electrical conductor from the housing of the device and each of the connection points. Resolved by the connection being made.

[Effect]

One substantial advantage of the invention is that the wiring is connected to the device, for example a control cabinet for controlling a printing press, by pre-shipment machining, so that during installation of the printing press the electrical conductors are simply connected by means of plug connectors. All you need to do is connect it to the printing machine. Therefore, the individual printing units and other components of the printing press do not have any exposed cables that could easily be damaged while they are being transported. A further advantage of the invention is that since there is only one connection point in between, the total transmission resistance between the control cabinet and each component of the printing press can be substantially reduced. Precisely when the number of electrical conductors is large, this means a significant reduction in transmission losses.

A further advantage is that immediately after the control cabinet has been manufactured, a complete check of the wiring and printing press controls may be carried out, for example using a simulator simulating the functionality of the printing press.

In addition, after installing the printing press with the control cabinet,
It is advantageous to carry out the check of the wiring itself by means of a central control unit installed in the control cabinet.

In one advantageous development of the invention, all input/output conductors of each printing unit or other component of the printing press are collected at one connection point,
A number of appropriate terminals are provided at this connection point. Each of these connection points can be provided with a removable connector, for example a plug connector. It is clear that in this way the installation of the printing press becomes even easier. Furthermore, after assembly of the printing press or its individual components, a check of the electrical function can be carried out, for example by connecting a checking electronic device to the respective connection point with a plug connector. In one developed embodiment of the invention, incorrect plug connections are prevented in the following way. That is, a cord is attached to a removable connector, or the length of the cable is determined so that it is impossible to make a connection error. In terms of cable length, all the individual cables leading to the press run together along one side of the press and branch out at each component of the press, making it It's decided.

In one developed embodiment, the electrical conductor leading to the drive motor of the printing press is also installed in the control cabinet before shipping, so that there is only one connection point. The connection points at each component of the printing press include distributors, which are covered by a case so that the plug connectors are accommodated without dirt or other environmental influences. It is advantageous if

Advantageous developments and improvements of the invention are possible by means of other dependent claims and measures indicated in the text.

〔Example〕

Next, embodiments of the present invention will be described with reference to the drawings.

The figure shows the configuration of a printing press with an attached control cabinet for overall control of the printing press.

The printing press 1 is a sheet-fed offset printing press and includes four printing units 4 to 7, a paper feed device 2, and a paper delivery device 3. The printing press is driven by a motor 39. Various sensors 16 to 25 are installed in the paper feed device 2, in the paper discharge device 3, and in the individual printing units 4 to 7, for example for controlling the loading of the feed paper, for controlling the lateral position, and for controlling the ink position. Sensors are installed for controlling the knife adjustment and, more generally, for controlling the state of other regulated elements, as well as for controlling the transport state of the paper sheets. Furthermore, there are a number of adjustment members 8 to 15 in the individual components of the printing press. The same applies to the sensor, but it is shown only schematically in the figure. As for the adjustment members, for example, it is known to use adjustment members to adjust the lateral direction and direction of travel of the paper sheet, and also adjustment members for adjusting the ink knife and the dampening water are also known. be. Additionally, each component of the printing press has operating elements (not shown) such as signal indicators, switches, emergency cut-out switches, and the like. All electrical conductors leading to these sensors, regulating elements, indicators or switches are collected in one distributor 26-31 for each printing unit 4-7, paper feeder 2 and delivery device 3. . These distributors 2

The distributors 26 to 3 are installed in a location with good accessibility.
The electrical conductors brought together terminate in one or more multiway connectors in the distributor. Distributor 26~
The connection between 31 and control cabinet 42 is made by a connecting cable 44. In the control cabinet 42 there is, for example, a control device 46 for generating control voltages, as well as a processing unit for processing the signals of the sensors. The connecting cables leading to the distributors 26-31 pass through the housing 45 of the control cabinet 42 and are connected to the control device 46.

In order to prevent the plug connectors 32 to 37 from being connected incorrectly, these plug connectors 32 to 37 are provided with
Although the cords are attached so that only one plug connector can be connected to a given distributor, it is important to match the lengths of the cables accurately, that is, to connect the individual cables together as a whole. Mistakes can also be prevented by making it impossible to make mistakes in the first place based on the external shape of the word.

The connecting cable 44 leads not only to the printing units 4 to 7, the paper feeder 2 and the paper ejector 3, but also to the drive motor 39 and one or more accessory devices 40. Plug connectors 38.degree. 41 can also be attached to these connecting cables 44. While the printing press is being transported to its installation location, the connecting cable 44 is connected to, for example, a control cabinet 42.
