Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0020] An exemplary embodiment of the invention is described in greater detail below with reference to the drawings. In the drawings, in partially highly schematic illustrations:

[0021] FIG. 1 shows a block diagram of a machine tool according to the invention, and

[0022] FIG. 2 shows a plan view of an operator control unit of a machine tool according to the invention, with a touch-sensitive display in the form of a central operator control element being shown together with a plurality of operator control keys, buttons, switches and levers.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0023] According to FIG. 1, a machine tool, which is denoted 1 overall, has at least one machine part 2 which can be adjusted by motor and which is connected to a drive unit 3 of the machine tool for the purpose of receiving control signals. The machine tool 1 additionally has a touch-sensitive display 4 which is arranged on an operator control console 5 according to FIG. 2. The drive unit 3 is integrated into this operator control console 5.

[0024] The drive unit 3 is designed to illustrate the machine part 2 in its instantaneous state on the display 4 and to adjust the machine part 2 depending on a swiping gesture which is executed on the display 4. According to FIG. 2, this swiping gesture, indicated by the double-headed arrows Pf 1 and Pf 2 and Pf 3, can be executed on the display 4 by a hand 6 of an operator of the machine tool 1.

[0025] The drive unit 3 is designed to detect a speed of the swiping gesture which is executed on the display 4. The display 4 is a pressure-sensitive display. That is to say, the pressure which is exerted on the display 4 by a swiping gesture which is executed on the display 4 can be detected or determined with the aid of the display 4. The drive unit 3 is designed to detect the pressure intensity of the swiping gesture which is executed on the display 4. In this way, an adjustment parameter of the adjustment movement of the machine part 2 can be derived from the pressure intensity of the swiping gesture on the display 4 and used by the drive unit 3 to drive and move the machine part 2.

[0026] As indicated by the double-headed arrows Pf 1, Pf 2, and Pf 3, this swiping gesture can comprise both rectilinear movements and also rotary or pivoting movements or else movements which are executed along a bent movement line on the display 4.

[0027] The drive unit 3 is also designed to set a speed of the adjustment of the machine part 2. The drive unit 3 is also designed to separately detect at least two simultaneous touches on the display 4. These at least two simultaneous touches can be executed by means of different fingers 7 of the hand 6 of the user or operator of the machine tool 1 or else by means of two hands or different fingers of two different hands on the display 4. FIG. 2 clearly shows that a virtual image 8 of the machine part 2, which is to be adjusted by motor, is depicted on the display 4 and that the user can “grasp” the virtual image 8 using a hand 6 and individual fingers 7 of the hand 6 and can adjust said virtual image in the desired manner by executing a swiping gesture on the display 4. In the process, the adjustment movement which is executed on the display 4 by the swiping gesture is transmitted to the machine part 2, which is to be adjusted, by the drive unit 3. Here, the arrows which are illustrated between the display 4 and the drive unit 3 and, respectively, between the drive unit 3 and the machine part 2 in FIG. 1 illustrate the flow of data and/or information.

[0028] The machine part 2 has two elements which can move relative to one another. The drive unit 3 is designed to trigger a relative movement of these elements toward one another by a swiping gesture which executes at least two simultaneous touches on the display 4.

[0029] The machine part 2 can be adjusted in at least two axes. In this case, the drive unit 3 is designed to separately adjust the machine part 2 in the at least two axes by means of different swiping movements which each trace one axis of the at least two axes on the display 4 in the correct position. In this way, the at least two axes of the machine part 2 can be adjusted or driven independently of one another by different swiping movements, for example by means of two different fingers 7 of one hand 6 or by means of two different fingers 7 of two different hands.

[0030] The drive unit 3 is additionally designed to calculate a correctly positioned illustration of an instantaneous state of the machine part 2 on the basis of a measurement signal from at least one sensor 9. In this way, the virtual image 8, which is illustrated on the display 4, of the machine part 2 can actually also correspond to the real or instantaneous state of the machine part 2, which can be adjusted by motor, on account of the data obtained from the at least one sensor 9 of the machine tool 1. The arrows which are illustrated between the sensor 9 and the machine part 2 and, respectively, between the sensor 9 and the drive unit 3 in FIG. 1 once again illustrate the flow of data and/or information.

[0031] An existing operator control concept, which comprises buttons, levers, switches or similar operator control elements 10, as are also illustrated on the operator control console 5 according to FIG. 2, can be replaced by or supplemented with the use of the touch-sensitive display 4 for driving the machine part 2, which can be adjusted by motor, of the machine tool 1.

[0032] The machine part 2 is displayed in its instantaneous state on the display 4. A virtual image 8 of the machine part 2 is displayed in this case. The machine part 2 can be adjusted by motor in the desired manner by executing a swiping gesture on the display 4.

[0033] In this case, a speed of an adjustment movement can be set depending on a speed of the detected swiping gesture in at least one drive mode.

[0034] The machine part 2 has the two elements which can move relative to one another. A relative movement of the elements toward one another is then triggered by a swiping gesture which executes at least two simultaneous touches on the display 4.

[0035] Particularly when the machine tool 1 has a plurality of machine parts 2, the machine part 2 which is intended to be adjusted can be chosen and also activated for adjustment by selecting the illustrated machine part 2 on the display 4.

[0036] The machine part 2 is adjusted in at least two axes separately from one another by the use of different swiping movements which each trace one axis of the at least two axes on the display 4 in the correct position (cf. double-headed arrows Pf 1, Pf 2 and Pf 3). As already indicated above, the instantaneous state of the machine part 2 is detected by the at least one sensor 9 (see double-headed arrows between sensor 9 and machine part 2 in FIG. 1). The virtual image 8 of the machine part 2 can then be generated on the display 4 by means of the data which is detected by the at least one sensor 9 and which is transmitted to the drive unit 3. The virtual image 8 of the machine part 2 corresponds to the instantaneous state of the machine part 2, which changes due to the adjustment by motor which is prompted by the swiping gestures which are executed on the display 4.

[0037] According to the invention, it is provided that the touch-sensitive display 4 is used on the machine tool, which has a machine part 2 which can be adjusted by motor, to display the machine part 2 in its instantaneous state on the display 4 and to adjust said machine part by motor by executing a swiping gesture on the display 4. Operator control of a machine tool 1 can be simplified as a result.
