DE4119803A1 - Acoustic prompting method for machine tool operation - using speech synthesiser module with programmed instructions and warnings, coupled to position display via interface - Google Patents

Abstract

In the method the main instructions are given to the machine operator acoustically. The instructions include information on the axis of travel, axial direction, and remaining distance to be covered. Warnings are given in cases of incorrect operation and to indicate that the machine is about to reach a set position. Fixed speech sequences stored in memory are selected and activated by the position display module w.r.t. the instruction step data. The speech synthesis module is coupled to the electronic circuitry of the position display module via a commonly available interface, e.g. an RS232. The sound is transmitted from a loudspeaker or via wireless headphones to the operator. ADVANTAGE - Operator can concentrate visually on machine or workpiece, without having to look at display.

Description

Support modern position indicators for multiple axes the operator of a machine tool via a display. According to the saved workpiece step program the machine operator is continuously provided with information about Target and actual positions or numerically via remaining routes and / or displayed graphically. In addition to the manual operation of the feed, the Operator always the workpiece to be machined and the Keep an eye on the screen of the position indicator.

The patent idea is a process and a technical one Concept for realizing an acoustic operator guidance underlying. The worker using a machine tool Position display is ongoing during processing operation about the axis to be traversed, axis direction and the current value of the actual position or the distance to go informed. There are acoustic warnings in the event of incorrect operation and before Reached the step target position output. The permanently programmed language sequences are used by the Position display according to the current step data selected and activated. For this purpose, a speech synthesis module is installed over an existing one Interface (e.g. RS 232) with the electronics of the Position indicator coupled. The acoustic announcement to the operator takes place in the respective national language via loudspeaker and / or wireless headphones (infrared coupled).

The basic principle of an acoustic operator guidance is shown in FIG. 1. A position indicator ( 1 ) with several measuring systems displays current data of the processing step on a numerical and / or graphic display. The position indicator communicates via a serial or parallel interface ( 2 ) with a CPU-controlled speech synthesis module ( 3 ), which selects permanently stored announcement texts of different lengths from an internal memory. The reproduction takes place via a loudspeaker ( 4 ) and / or an infrared transmitter diode ( 5 ) is modulated for a wireless headphone ( 6 ).

The advantage of the method is that the Machine operator optically fully on workpiece and machine can concentrate. The supportive acoustic operator guidance in form gives spoken instructions and warnings to the worker on the machine tool more safety during loading work process and allows faster work, since the view to the display is only for control purposes is required.

Claims (1)

A method for acoustic operator guidance on a hand-operated machine tool in the context of workshop-oriented programming, characterized by an electrical coupling of a speech synthesis module with permanently programmed instructions and warnings to a position indicator via an interface.
