Control device for a machine tool and method for controlling the machine tool

Abstract

The invention relates to a machine controller, comprising a sensor module (4), an evaluating module (9), and a control module (5), wherein the sensor module (4) has a converter, which converts a mechanical quantity acting on the sensor module (4) into a proportional electrical parameter and wherein the evaluating module (9) is connected to the sensor module (4) by means of a first signal connection (8) and to the control module (5) by means of a second signal connection (11). The evaluating module (9) forms a signal profile from the detected electrical signal by means of a potential analysis and / or a change analysis. The signal profile is compared with at least one reference signal profile stored in a storage element of the evaluating module (9) by a comparison module of the evaluating module (9), and the control signal is generated therefrom. Furthermore, at least one of the two signal connections (8, 11) is designed to be wireless.

Description

technical field [0001] The invention relates to a machine control device, which includes: a sensor module, an analysis and processing module and a control module. Background technique [0002] In machine controls, in particular in machine controls for press brakes or bending machines, there is a requirement to ensure reliable operation of the press or bending function, in particular even when actuation by the operator is required when working. Precisely when machining small components or components with complex bending lines, it is often necessary for the operator to orient the workpiece accordingly relative to the bending tool until the bending process begins and to initiate the bending process by actuating the trigger element. Devices are known from the prior art in order to ensure that no body part is between the pressure beam and the stop beam of the bending die during the bending process, thus preventing the operator from being injured. For triggering the bending proc...

However, the disadvantage of this configuration is that such a safety switching element is accompanied by additional switching technology and installation costs, because the switching components required for this configuration make the machine control device flexible. Applicability is limited

[0005] What the prior art does not disclose is that, in addition to pure start-stop information, additional variable control information can be transmitted from the operator to the machine control
