DD208879A1 - CONTROL AND STORAGE DEVICE FOR SEVERAL GROUP-ORIENTED TRANSDUCERS - Google Patents

Abstract

The invention relates to a control and storage device for a plurality of sensors arranged in a group on printing, bookbinding and cutting machines. The object of the invention is to provide a control and storage device which requires less memory units. The resulting technical task is to design the device so that only the values of the respectively required transducers are stored. The object of the invention is achieved by arranging a respective memory module in each group to be interrogated, whose outputs are connected to a multiplexer and this multiplexer is preceded by a memory circuit whose output is connected to the clock input of the memory modules and one for controlling the Ablaefe is arranged upstream in the switching phase and zuchaltung, which is connected with its output to the clock input of the memory modules and that one for controlling the Ablaeufe in the switching phase and zucherschaltung is connected. All functions except storage can be taken over by the microcomputer.

Control and storage device for a plurality of group- like arranged transmitter

Field of application of the invention

The invention relates to a control and storage device for a plurality of group-like arranged transducers on printing, bookbinding and cutting machines.

Characteristic of the known technical solutions

Known according to DE-AS 27 28 738 a device for controlling and regulating the color of printing presses, which consists of arbiter [...] elements, Positionungsmeßgebern, consisting of a composite system of computers control unit, a Sin- and output unit and storage media, each of which Storage medium is assigned to a position transmitter exists.

The disadvantage here is that for each Steliungsmeßgeber a separate memory device is required, although only a certain number of Sinstelldaten queried at the same time from the computer -wird.

Object of the invention

It is the object of the invention to provide a control and storage device which requires less effort *

Explanation of the essence of the invention;

The technical object of the invention is to make the Xontroll- and Speiehereinrichtung so that only the values of each required transmitter stored v / earth.

The object is achieved in that the respective optionally queried transducers of each group a memory module is arranged downstream, whose outputs are connected to a multiplexer and this multiplexer is preceded by a memory circuit which is connected with its output to the clock inputs of the memory modules and that one for controlling the processes in the Umsehaltphase and generating group select signal s of each group to be activated serving control circuit with the transducers, the memory devices, the multiplexer and the memory circuit is connected.

Effectively, the control circuit is characterized by being formed as a microcomputer.

Pur a digital data acquisition, it is convenient that the transmitter are designed as incremental pulse.

Advantageously, the design of the memory device is characterized in that it has a ΗΑίί-Schaitkreis.

A useful variant of the multiplexer is that the multiplexer is designed as a microcomputer.

Useful in terms of cost reduction, the design of the control and memory device is characterized in that the multiplexer, the memory circuit and the control circuit are formed together as a microcomputer.

embodiment

The invention will be explained in more detail below with reference to a Ausführurigsbeispieles.

The block diagram of the control and storage device shown in the drawing contains a Farbzonenferaverstellung mounted on not shown ink fountain keys Stellmotore and Positionungsmeßgeber. The first position transmitter 1 and the position sensors arranged up to the η-th position transmitter 2 are mounted in the first inking unit 3. The position sensors from the mth position measuring transmitter 4 to the last position measuring transmitter 5 are located in the last inking unit β.

The respective first position sensors 1, 4 of each inking unit (first .Farbwerk, last inking unit) are connected on the output side and connected to the input of the first memory module 7 ·

At the last memory module 8, the last last position-connected Positionungsmeßgeber 2, 5 are connected. The number of memory modules corresponds to the largest number of simultaneous position sensors to be interrogated. The multipleser 9 is connected to the outputs of the memory modules via its inputs via the data feed 18. The data sequentially fetched by the multiplexer 9 enter the memory circuit 10 via the data bus 17.

By means of the control circuit 11, the corresponding memory location in the memory circuit 10 is allocated via the group address feeder 13 and the channel address feeder 12. Furthermore, the write / read signal is transmitted to the memory circuit 10 by the control circuit 11 via the control line 14.

A corresponding activation of the respective group of position sensors to be interrogated in the corresponding inking unit likewise takes place via the group selection lines 15 by the control circuit. The data in the memory modules are connected to the control circuit 11 via the multiplexer 9 after receiving the memory data

Control lines 1o cleared.

In the described Äusführungsform the position transmitter of a. Channel can be interconnected so that the non-active position transmitter does not affect the puncture of the active position sensor. This requirement can be realized by the outputs of the position sensors are in the inactive state high impedance.
