Abstract

The circuit arrangement for the acquisition of operating data, such as time measurement, Stueckzaehlung and Laengenerfassung, is applied to Schnellverseilmaschinen Stahlcordherstellung. It should be eliminated in this case the known disadvantages of mechanical recording devices. The object of the invention is to capture the accumulated operating data exactly, store it over a certain period of time and keep it ready for use, thus evaluating the machine utilization and production output. The task is solved by signals via the sensors of the circuit, which are correspondingly converted and counted via input amplifiers, gates, quartz time base and counter, and output amplifiers, multiplexers and a counter call are stored accordingly and registered and stored on a display with an indicator. The output amplifier can be used to connect a computer, printer or an additional secondary display. A power supply is used to power the individual components and a battery for power supply in case of power failure.

Title of the invention

Circuit arrangement for operating data acquisition

Field of application of Srfindune;

The invention can be used in production machines in which the acquisition of specific operating data is required, but especially on high-speed stranding machines for steel cord production.

Characteristic of the known technical solutions

Circuit arrangements are known in which a registering, detecting and monitoring of operating conditions, such as working idle fault time u. Ä., Is done. For this purpose, as far as possible, electromechanical counters, electrical or electronic recorders and other mechanical recording devices are used »

The disadvantage here is a high wear of the mechanical counting devices and a low reliability and a relatively high maintenance costs

Another shortcoming is the use of predominantly precision mechanical elements. A combination of several operating data with each other and a complex further processing and evaluation of the determined data is not possible known is the DD-PS 143 485, in the machine running times and the actual machine operating times depending on the predetermined number, within a limited time, are precisely detected and evaluated · However, there is no evaluation of all accumulating operating data over a longer period of time, but only in given specific 'cycle times.

In a device for detecting disturbance times for production facilities, the recording of disturbance times for the registration of running in a certain cycle time operations, in particular the passage of workpieces, the task is the detection of interference and interference. Sine recording of production capacity and utilization of the machine is not done here. In DE-OS 25 13 818, which is used to monitor operating conditions, actual operating state data of a control element and predetermined reference operating state data are compared and determined the differences between these data »When changing the control process of the control element, the consequent new operating state data in a memory recorded and saved as new reference operating state data ©

Object of the invention

It is an object of the invention to develop a circuit arrangement which eliminates the known disadvantages such as high wear, low reliability and relatively high maintenance of mechanical registration devices, which serve for concentrated detection of the machine utilization

Explanation of the essence of the invention

The invention has for its object to accurately detect the operating data occurring at a plant in operation, such as time measurement, piece counting and length detection, store over a period of time and keep ready to retrieve and thus evaluate the machine utilization and production capacity _e

According to the invention, this object is achieved by signals generated by the sensors located in the system and supplied to an input stage. The signals are routed once via a frequency divider and a gate to which a quartz time base is assigned, and directly to the counters.

The counters are followed by a meter call and this an indicator, which displays the respective counter called. The determined and stored data of the counter can be called up individually and displayed via a multiplexer at the indicator panel "via an output stage, which is nachgesohaltet the first counter, the output thus determined _o machine capacity or BCD code at the output of the circuit arrangement made available, wherein for the central evaluation of the connection of a computer, printer or _o a second display is possible »To the power supply of the individual building blocks a power supply is arranged, and in case of power failures a battery takes over the voltage supply for the components» The display and storage of the determined data is dimensioned, that the counting capacity can be extended to more than one month »

Ausführunssbeispiel

The invention will be explained in more detail by the following example.

The signals appearing on the machine are fed to input stage 1. ο In these signals are suppressed and the signal levels are processed for processing. The signal for the production capacity is divided in the divider 2 in a ratio of 1: 1000 and then fed to the counter 5 · counter 6 receives its counts directly, according to the number of occurring wire tears ο ^ counter 7 and 8 are via gate 3 and quartz ze it base 4 driven _o the quartz ze itbasis 4 generates minute pulses _s 7 and 8 are supplied to the counters as long as the gate 3 is opened * means counter call 9, the content of counter 5, 6, 7 or 8 via multiplexer 10 for display 11 brought. Indicator 12 displays the number of the called counter. The output stage 13 provides a TTL kompaktibIes BCD-coded signal at the output of the circuit, the output stage 13 only the content of the counter 5 is provided for further processing available. It is possible to have a printer or a secondary display at the output of the output stage
