The invention relates to an operating element for entering a command in the control of an electrically controlled machine.
An operating unit for an injection molding machine is known from AT 512 521 B1. The operating unit has an operating element for triggering at least one movement of a drive unit of the injection molding machine, the operating element being movable from a basic position into a triggering region which triggers the movement of the drive unit. The trigger area has a large number of intermediate positions between the basic position and a maximum position. The speed of the triggered movement of the drive unit depends on the distance of the selected intermediate position of the control element from the basic position. Movements of several drive units can be triggered by the control element, the drive units controlled by the control element being changed by pressing, pulling, pivoting, etc. of the control element.
The control unit known from AT 512 521 B1 has the disadvantage that an control element which executes commands by pressing, pulling, swiveling etc. must have a corresponding mechanical coupling to a switch. Such a coupling is prone to errors and expensive. In addition, such a coupling is difficult to implement, for example in explosion-protected areas.
The object of the present invention was to overcome the disadvantages of the prior art and to provide an improved control element. In addition, it was the object of the invention to provide an improved method for
2/39
N2017 / 28000-AT-00
To enter a command into the control of the electrically controlled machine.
This object is achieved by an operating element according to the claims.
According to the invention is a control element for an electrically controlled machine, with a control element body and a rotary wheel for entering a command in a control of the machine, the rotary wheel being arranged on the control element body so as to be rotatable about an axis of rotation and being surrounded by a lateral surface which is local in the normal direction the rotational axis has a predetermined mean diameter, on the lateral surface of which the rotary wheel can be gripped and rotated by a machine operator, the lateral surface of the rotary wheel having at least two actuating sections, each with different, haptically distinguishable surface structures, at least one of the actuating sections being assigned a sensor area of a sensor element, which Sensor area is provided or designed for the detection of the presence and / or non-presence of touch by a machine operator, and at least one of the actuators Different machine functions, in particular movement control commands, are assigned to the input of at least one command into the control, and the at least two actuating sections are arranged on the outer surface of the rotary wheel in such a way that they can be grasped by a machine operator with one hand and / or their fingers.
The different surface structuring of at least two functionally different actuation sections on the rotary wheel allows the machine operator to provide tactile or haptic feedback in a simple manner about which actuation section his hand or at least one of his fingers is sensing. This enables a machine operator to focus his attention primarily on the work area of the electrical machine. In extreme cases, the machine operator can work completely away from the control element thanks to the intuitively designed surface structures of the rotary wheel. Due to the different surface structures of at least two actuations
N2017 / 28000-AT-00 sections, accidental actuation of an incorrect actuation section is significantly reduced. This increases the safety of the machine operator and the machine controlled by the machine operator. An increase in process reliability for the electrical machine, the tools and workpieces used is particularly favored here. Another advantage of the design of the control element according to the invention is that a large number of different control commands can be carried out by means of the control element, the control element nevertheless having a relatively simple construction. Furthermore, the surface structuring can significantly improve the grip of the machine operator's hand on the rotary wheel.
In addition, the rotary wheel can be coupled to the control element body by means of a simple rotary sensor, for example an incremental encoder or an absolute value encoder. The rotary sensor on the control element body can be functionally coupled to the at least two actuating sections or the sensor elements of the sensor areas of the rotary wheel. The selection and / or input of parameters into the control of the machine takes place via the rotary wheel, the rotary sensor detecting the rotary or rotational movement of the rotary wheel. Depending on the position of the hand or fingers of the machine operator, the at least two actuating sections of the rotary movement of the rotary wheel can be uniquely assigned by a controller connected to the rotary sensor, in particular a control and / or evaluation device. A very simple, comfortable and quick entry of a command, in particular a movement control command, into the control of the machine is thus possible. It is particularly advantageous if the rotary wheel has no mechanical end stop in the direction of rotation.
Furthermore, it can be expedient if the actuating sections having at least two different surface structures are arranged at a distance from one another in the direction of the axis of rotation and are formed on the circumferential surface in the full circumferential direction of the respective sensor region. It is particularly advantageous if the surface structuring is around the ge4 / 39
N2017 / 28000-AT-00 entire circumference are formed, as they can be perceived by the machine operator regardless of an angle of rotation of the rotary wheel. It is also advantageous that a first sensor area on a first actuation section can be used to confirm input commands, e.g. the confirmation command can be triggered by axially shifting the hand of the machine operator. The axial spacing or arrangement of the actuating sections in the direction of the axis of rotation has the advantage that, by moving one hand of the machine operator, several actuating sections can also be achieved with one hand. Adequate spacing can already be provided by separating the actuating sections in the circumferential direction. A groove or notch may be sufficient for separation.
Furthermore, it can be provided that the at least two actuating sections of the rotary wheel are rotatably mounted relative to the control element body via a common axis of rotation. This means that the actuating sections of the rotary wheel are rigidly coupled and can therefore only be moved simultaneously in the circumferential direction of the rotary wheel. The connection of the at least two actuating sections to the control element is thereby very structurally simplified, since the connection point between the rotary wheel and the control element body can be designed in the form of a simple rotary sensor, as a result of which the rotary wheel has a low susceptibility to errors. On a complicated structure using e.g. Several hollow axes, each of which is assigned to an actuating section, can be dispensed with in this way. The entry of at least one command into the control is made possible by the detection of the position of a hand or the fingers of the machine operator on the respective actuation section.
In addition, it can be provided that the rotary wheel in its basic contour is rotationally symmetrical, in particular cylindrical, and the local mean diameter of the lateral surface is between 20 mm and 80 mm, in particular between 35 mm and 60 mm, preferably between 40 mm and 50 mm. The basic contour here is the “envelope” of the outer surface of the rotary wheel
5/39
N2017 / 28000-AT-00 to understand along its axis of rotation. The basic contour of the rotary wheel thus corresponds to the outer shape of the rotary wheel that the machine operator grips. Through a rotationally symmetrical, and in this case preferably cylindrical, design of the rotary wheel, it can also be achieved that the hand of the machine operator can slide axially well along the rotary wheel and thus the individual input commands can be selected and / or confirmed well.
The advantage here is that a rotary wheel constructed in this way is easy to grasp and operate by the machine operator.
Also advantageous is a configuration according to which it can be provided that at least one of the actuating sections along the axis of rotation has different, in particular continuously and / or discontinuously increasing and / or decreasing, local average diameter values of the lateral surface. The handling of a rotary wheel can e.g. be decisively improved by paragraphs and / or by graded and / or by gradual transitions. The rotary wheel can have a different local mean diameter at each point of its axis of rotation. It is advantageous here that the position of the hand or fingers on the lateral surface of a rotary wheel constructed in this way is relatively easy for the machine operator to grasp. Incorrect operation and / or unintentional confirmation of a command to the machine control can be largely avoided. Furthermore, the machine operator is given a particularly ergonomic and fatigue-free work by adequately shaping the rotary wheel by means of heels, but especially curves. This improves the concentration of the machine operator and thus the quality.
According to a development, it is possible for the surface structuring of at least one of the actuating sections to have round and / or elongate elevations, such as Ridges, knobs, pyramids, and / or depressions, such as Grooves, grooves, dents, honeycombs, dimples, dimples, compared to the local average diameter of the lateral surface. The position of the hand or fingers on the lateral surface, and thus the at least two actuation sections, can thus be perceived immediately by the machine operator. Is an advantage
6/39
N2017 / 28000-AT-00 that the machine operator “feels” the relative position of his hand or fingers on the rotary wheel when the rotary wheel is gripped. In the context of this invention, the term surface structuring encompasses the nature of the surface, in particular the lateral surface, of the rotary wheel.
In the foreground, surface structuring therefore means that the person skilled in the art can specify surface features such as elevations or depressions for a suitable design of the surface of the actuating sections. However, it should be explicitly pointed out here that in the context of the invention, a “smooth” surface of one of the actuating sections can also be understood as surface structuring. Here, "smooth" can be understood to mean a surface which, e.g. has an injection molding, casting, rolling, milling, turning or profiling surface in the course of the manufacturing process of the rotary wheel. It is also conceivable that the surface after mechanical and / or chemical processing, e.g. is subjected to an etching process. The different surface roughness can already be perceived by a machine operator as different surface structures.
From a manufacturing point of view, it is advantageous if an actuating section therefore has a “smooth” surface, as results from the manufacturing process. This “smooth” surface essentially does not require any additional effort for the surface structuring and, due to the different surface structuring of the other operating sections, is nevertheless sufficiently tactile and / or haptically distinguishable for the machine operator. A combination of different elevations and / or depressions and / or surface roughness for the design of an actuating section is also conceivable.
Furthermore, it can be expedient if the elongate elevations and / or depressions have a ratio of a greater extent to a shorter extent of the elevations or the depressions on the lateral surface of greater than 1.5, preferably greater than 5. It is advantageous to provide the surface structuring in a sufficient size to ensure that the elevations and / or depressions can be distinguished from one another. This is
7/39
N2017 / 28000-AT-00 especially helpful if e.g. elongated dents or webs are formed as surface structuring. This also means closed raised elevations and / or depressions in the circumferential direction. It also means elevations and / or depressions inclined in the direction of the axis of rotation or at an angle to the axis of rotation.
In addition, it can be provided that the surface structuring of at least one of the actuating sections is formed uniformly over the lateral surface of the respective actuating section. This simplifies the assignment of a surface structure to an individual field of activity.
Furthermore, it can be provided that the surface structuring of at least one of the actuating sections is formed symmetrically in at least one direction, preferably in the circumferential direction, over the lateral surface of the respective actuating section. The symmetrical design of the surface structuring offers manufacturing advantages and can be realized relatively inexpensively. Furthermore, the starting position of the rotary wheel when it is gripped by a machine operator is irrelevant if the rotary wheel has no mechanical stop. In addition, a machine operator does not have to “relearn” from a rotary wheel of an operating element of a machine to another rotary wheel or an operating element of another machine.
According to a special embodiment, it is possible for the surface structuring of at least one of the actuating sections to be irregularly formed over the lateral surface of the respective actuating section. For certain applications it can be advantageous if the surface structuring is irregularly formed over sections of the rotary wheel. This can e.g. be the case with brushed or shot-peened surfaces. Such methods often do not form sharply defined interfaces at the edge areas. However, these surface structures can be implemented in a relatively simple manner and therefore in a cost-saving manner.
8/39
N2017 / 28000-AT-00
According to an advantageous development, it can be provided that the surface structuring of at least one of the actuation sections has a ratio of the deviation of the largest elevation and / or lowest depression of the lateral surface in the normal direction to the axis of rotation to the local mean diameter of greater than 0.001, preferably 0.005, particularly preferably greater than 0, 01 has. It has proven to be advantageous that the surface structuring, especially in the form of elevations and / or depressions, scales with the basic contour or the local mean diameter. It has been shown that a minimum deviation of the elevation and / or deepening from the local mean diameter value is particularly favorable for sufficient tactile and / or haptic perception by the machine operator.
In particular, it can be advantageous if the lateral surface of at least one of the actuating sections consists predominantly of metal. This favors a particularly robust construction of the rotary wheel. It is advantageous here that sensor elements for a conductivity measurement can be used in at least one of the actuation sections. A high sensitivity and thus a good recognition of the position of the hand or fingers of the machine operator is thereby facilitated.
Furthermore, it can be provided that the surface structuring of at least one of the actuating sections has at least partially a second material, preferably plastic. For an optimal differentiation between two different surface structures, it has been shown that not only geometrical features but also the "feeling of attack" can play a role. It can therefore be advantageous if a second material, e.g. has a higher, felt surface temperature than the first material. In addition, surface structuring from one or more other materials can be applied relatively easily. Here are e.g. Spraying, gluing or coating processes and the like are conceivable. Furthermore, the security against slipping of the hand or fingers of the machine operator can be increased by the selection of a further material. This offers clear security advantages. In the event that the dial is made of metal, it offers a second material, and
9/39
N2017 / 28000-AT-00 in this case in particular a dielectric material, such as Plastic, the advantage that one or more sensor elements assigned to the actuating sections can be designed as capacitive sensors. Such capacitive sensors can e.g. be designed as proximity sensors, displacement sensors, acceleration sensors or also pressure sensors. The variety of possible commands to control the machine is significantly increased.
In addition, it can be provided that at least one actuating section has a pressure-sensitive sensor element. The parameter selection, confirmation of commands and the like can be carried out by means of the control element according to the invention via the at least two actuating sections of the rotary wheel in relation to the control of the machine. However, it has proven to be particularly advantageous that a pressure-sensitive sensor element is provided for signaling an exceptional state, in relation to the control of the machine. A machine operator can recognize a dangerous situation for e.g. the tool or the workpiece trigger a “stop command” to the machine control by exerting a force. Accidental operation is efficiently avoided by the "normal operating mode" via the rotary movement of the rotary wheel and confirmation of the commands by moving the fingers over at least one operating field. The sensor area of the pressure-sensitive sensor element can lie on the lateral surface in the circumferential direction.
Also advantageous is a configuration according to which it can be provided that the pressure-sensitive sensor element is arranged in such a way that its sensor area is oriented essentially in the direction of the axis of rotation. It is advantageous here that for the “normal operating mode” of the rotary wheel essentially only rotational movements of the rotary wheel about its axis of rotation, as well as displacements of the hand or fingers of a machine operator on the outer surface of the rotary wheel are required. A movement in the direction of the axis of rotation on the pressure-sensitive sensor element that is associated with a force represents a large, and therefore clear, difference from the “normal operating mode” and can therefore be clearly assigned to an exceptional situation by the machine operator. The introduction of force in the direction of the axis of rotation can in
10/39
N2017 / 28000-AT-00
In a borderline case, the machine operator can even hit the rotary knob. This enables the machine operator to respond quickly, which increases safety during operation.
According to a development, it is possible for the rotary wheel to be mounted on the control element body so as to be displaceable in the direction of the axis of rotation, and for a switching or sensor element to be formed which, depending on the displacement of the rotary wheel along its axis of rotation, is provided for signaling or triggering a quick stop or emergency stop command is. In this development, it is advantageous that the command input for an exceptional situation in the control of the machine is decoupled from the at least two actuating sections on the lateral surface. Due to the compact design of the rotary wheel, which has only one common axis of rotation for the at least two actuating sections, a displacement of the rotary wheel along its axis of rotation can be carried out very easily by the machine operator. The position of the force application on the rotary wheel is therefore of minor importance for the displacement. In the extreme case, this can even be done by the machine operator striking the rotary wheel so that a shift in the direction of the axis of rotation is initiated. It has been found that the machine operator perceives displacement of the rotary wheel very well. The switching or sensor element, which is provided for signaling a "quick stop" or "emergency stop command" to the machine control system, can be installed very simply and robustly in the operating element. This represents an inexpensive and very safe design. It can also be provided that the rotary wheel is locked in its position after being displaced along the axis of rotation. In this case, the rotary wheel can only be released after the quick stop or emergency stop command has been acknowledged.
In addition, it can be provided that a machine function selected from the group machining feed, spindle speed, idle feed, axial infeed, radial infeed, tool change is assigned to a first, second and / or further actuation section. The invention 11/39
Control element according to N2017 / 28000-AT-00 has proven to be particularly advantageous for the control of production plants or machine tools. In particular, the operation of e.g. CNC milling machines, CNC lathes, but also injection molding machines can be significantly facilitated by the control element. In the case of CNC milling machines, the most common functions or movement commands of the machine, such as Machining feed, spindle speed and travel speed at idle (idle feed) can be operated relatively easily using the actuating sections provided on the rotary wheel and entered into the machine control system. Other functions, such as axial infeed, radial infeed or tool change, can also be entered into the machine control by means of the control element according to the invention.
All of the sensors arranged on the rotary wheel can be designed as individual sensor elements which are provided to detect the respectively associated sensor area. However, it is also conceivable that two or a plurality of sensor elements, which detect the sensor area, are assigned to a sensor area. Providing several sensor elements for one sensor area can have the advantage that redundancy is made possible and therefore failure of one sensor element can be compensated for. This may be necessary in particular to increase machine safety.
In particular, it can be provided that the sensor elements are designed to detect touches by the machine operator in certain areas or operating sections of the rotary wheel.
The sensor elements themselves can be designed as resistive sensors, for example.
Another possibility is that the sensor elements are designed in the form of optical sensors.
In general, the sensor elements can be realized by any sensor elements that are suitable for touching the rotary wheel by the
12/39
N2017 / 28000-AT-00
To grasp the hand or fingers of the machine operator. The sensor elements are particularly preferably designed as capacitive sensors.
The sensor elements can be arranged on the surface of the rotary wheel, or cast into the rotary wheel or integrated by other measures, such as the provision of corresponding receiving areas.
In particular, a combination of sensor elements with surface structuring of the actuating sections is conceivable.
For a better understanding of the invention, this will be explained in more detail with reference to the following figures.

The location information selected in the description, e.g. above, below, on the side, etc., referring to the figure described and illustrated immediately, and if the position is changed, these are to be applied accordingly to the new position.
1 shows a schematic representation of a production system 1 with an electrically controlled machine 2, a controller 3 for the machine 2 and an operating element 4 for entering control commands into the controller 3 of a machine operator 5. In particular, it is provided that the machine operator 5 uses the operator Hand 6 controls 4.
The machine 2 can be, for example, a milling, turning or injection molding machine. Furthermore, it is also conceivable that machine 2 is a robot or another machine in industrial use. In particular, it can be provided that the machine 2 is used to manufacture components.
The controller 3 can be formed by any conceivable type of controller. This can be, for example, an industrial computer, a programmable logic controller or another controller which is suitable for converting the commands entered via the operating element 4 into movement commands for the machine 2.

N2017 / 28000-AT-00
2 and 3, the control element 4 is shown in a front view and in a side view.
As can be seen from these two figures, it can be provided that the control element 4 has a control element body 7, which forms the central component of the control element 4 and can be defined, for example, by a housing. It can further be provided that a display 8 is accommodated in the control element body 7. The display 8 serves to display menu items, speed settings and other parameters or options which are necessary for the control of the machine 2. In a further embodiment variant, it can also be provided that the display 8 is not integrated in the control element 4, but that the display 8 is arranged elsewhere in the production system 1.
In addition, it can be provided that the control element 4 is arranged in a stationary manner on the production system 1 and is coupled to the production system 1 by means of a wired connection.
In an alternative embodiment variant it can also be provided that the control element 4 is designed in the form of a remote control and communicates with the controller 3 via a wireless connection.
Furthermore, it can be provided that the control 3 is integrated in the control element 4 and the control commands are given directly from the control element 4 to the machine 2.
As can also be seen from FIG. 2, it can be provided that one or more push buttons 9 are arranged on the operating element 4. The push buttons 9 can be used to enter various commands into the control element 4 by the machine operator 5.
According to the invention, a rotary wheel 10 is arranged on the control element body 7 and ver15 / 39 with respect to an axis of rotation 12 relative to the control element body 7
N2017 / 28000-AT-00 is rotatable. The rotary wheel 10 forms a central component of the control element 4. The push button 9 can optionally be omitted from the control element body 7 and its function can also be implemented in the rotary wheel 10.
Contrary to the designs known from the prior art, it is provided that the rotary wheel 10 can only be mounted on the control element body 7 such that it can rotate about the axis of rotation 12. The rotary wheel 10 is mechanically connected to the control element 7 by means of an axis of rotation 25 and is rotatably supported. As a result of the design of the rotary wheel 10, which will be described in greater detail below, it is not absolutely necessary that it be axially displaceable or pivotable relative to the control element body 7.
Because the rotary wheel 10 is only rotatably received on the control element body 7, the connection point between the rotary wheel 10 and the control element body 7 can be designed in the form of a simple rotary sensor, as a result of which the rotary wheel 10 has a low susceptibility to errors. The connection point of the rotary wheel 10 can be designed as an “endless stop”. In this case, there is no mechanical end stop of the rotary wheel 10 in the direction of rotation.
In particular, it can be provided that the rotary wheel 10 has a lateral surface 11 which surrounds the axis of rotation 12 and serves for the machine operator 5 to be able to grip the rotary wheel 10 and to rotate with respect to its axis of rotation 12. In particular, it can be provided that the lateral surface 11 of the rotary wheel 10 is essentially rotationally symmetrical with respect to the axis of rotation 12 and has a local mean diameter value 13.
The lateral surface 11 of the rotary wheel 10 can have at least two actuating sections 14, 15 with different surface structures 17. A sensor area 18, 19 of a sensor element 21, 22 is assigned to at least one of the actuating sections 14, 15. Different machine functions for inputting at least one command into the controller 3 can be assigned to each of the actuating sections 14, 15 of the rotary wheel 10. The actuating sections 14, 15 are arranged on the lateral surface 11 of the rotary wheel 10 in such a way that
16/39
N2017 / 28000-AT-00 that the machine operator 5 can grasp them with one hand 6 or one or more fingers of the hand 6, as shown in FIGS. 4 to 7.
Furthermore, it can be provided that a first actuating section 14 is formed on the rotary wheel 10, the sensor region 18 of which comprises the section of the lateral surface 11 of the rotary wheel 10 that is detected by a first sensor element 21. Furthermore, it can be provided that a gripping area 29 is formed on the lateral surface 11 of the rotary wheel 10, which is axially spaced from the actuating section 14 or the first sensor area 18. In particular, it can be provided that no sensor element is arranged in the gripping area 29.
As can also be seen from FIG. 3, it can be provided that the first actuating section 14 is arranged closer to the control element body 7 than the gripping area 29. In the exemplary illustrations in FIGS. 3 to 7, a rotary wheel 10 is shown, which has a shoulder. Further embodiments of geometries for a rotary wheel 10 in FIG. 8 apply to one another in addition to FIGS. 3 to 7 and 9 in the same way for the present invention.
The first actuating section 14, as well as a corresponding sensor area 18, can be formed on the rotary wheel 10 in full and have a sufficiently large axial extent to be able to grasp the hand 6 of the machine operator 5.
Furthermore, it can be provided that at least one second actuating section 15 with a corresponding second sensor region 19 and sensor element 22 detecting this sensor region 19 is arranged on the rotary wheel 10. In particular, it can be provided that the second sensor region 19 completely covers the section of the lateral surface 11 of the rotary wheel 10 that is occupied by the second actuating section 15.
It is particularly advantageous if the actuating sections 14, 15 having at least two different surface structures 17 are arranged at a distance from one another in the direction of the axis of rotation 12. A sufficient 17/39
N2017 / 28000-AT-00 appropriate spacing can already be given by a separation of the actuating sections on the lateral surface 11 in the circumferential direction 24. A groove or notch may be sufficient for separation. The surface structuring 17 can be formed around the entire circumference of an actuating section 14, 15, as a result of which it can be perceived by the machine operator 5 regardless of an angle of rotation of the rotary wheel 10.
4 to 7 different possible positions of the hand 6 of the machine operator 5 are shown.
4 to 7, the control element 4, as was shown in Fig. 3, is used. 8 and 9, the control element 4 is not shown in order to put a greater focus on the embodiments of the rotary wheel 10.
4 shows a first possibility of how the rotary wheel 10 of the operating element 4 can be gripped. According to the representation in FIG. 4, the rotary wheel 10 can be gripped in the gripping area 29, it being possible for no sensor element to be formed in the gripping area 29. Because it can be provided that all other areas of the rotary wheel 10 can be equipped with actuating sections 14, 15, the hand 6 or fingers of the machine operator 5 can also be clearly assigned to the gripping area 29 when the rotary wheel 10 is rotated.
In the event that the gripping area 29 does not have a corresponding sensor area, the gripping area 29 can nevertheless serve as an independent actuating section 14, 15. A rotary movement of the rotary wheel 10 by the machine operator 5 attacking the gripping area 29 can accordingly be assigned to one or more commands for the controller 3 of the machine 2.
As can be seen from FIG. 5, it can also be provided that the hand 6 of the machine operator 5 grasps the rotary wheel 10 in the first actuating section 14 or first sensor area 18. This can also trigger a separate command in the controller 3 of the machine 2.
18/39
N2017 / 28000-AT-00
Furthermore, it can be provided that, as shown in FIG. 6, the hand 6 or fingers of the machine operator 5 grips the rotary wheel 10 in such a way that both the first actuation section 14 or the first sensor region 18 and the second actuation section 15 or the second sensor area 19 are touched. This can also trigger your own command. For the sake of brevity, the rotary wheel 10 is gripped in the second sensor region 19.
For example, it is possible for the hand 6 or finger of the machine operator 5 to slide forward from a position as shown in FIG. 5 into a position as shown in FIG. 6. This movement is preferably used as a confirmation command.
The control element 4 according to the invention has proven to be particularly advantageous for the control of production plants 1. In particular, the operation of e.g. CNC milling machines, CNC lathes, but also injection molding machines are made significantly easier by operating element 4. In the case of CNC milling machines, the most common functions or movement commands of machine 2, such as Machining feed, spindle speed and travel speeds between the machining steps can be operated relatively easily by means of actuating sections 14, 15 provided for this purpose on the rotary wheel 10 and entered into the controller 3 of the machine 2. Other frequently used functions of the machine 2, such as axial infeed, radial infeed or tool change, can be selected and confirmed in the same way by means of the rotary wheel 10 or optionally made accessible to the machine operator 5 via one or more push buttons 9.
As can be seen from FIGS. 4 to 6 and explained for the respective figures, it can be provided that different commands can be given to the controller 3 of the machine 2 by the respective posture of the hand 6 or the fingers of the machine operator 5. In particular, movements of the machine 2 or a tool of the machine 2 can be selected in one direction and their travel / movement speeds can be set by the machine operator 5 using the rotary wheel 10. For example, a forward movement of the machine 2
19/39
N2017 / 28000-AT-00 or a tool of machine 2 can be selected in two different specified travel speeds or a backward movement in two different specified travel speeds and also a travel stop in the display 8. In a first mode it can be provided that the rotary wheel 10 is gripped in the first actuating section 14 or sensor area 18 as shown in FIG. 5, a selection field being drawn over a field in the display 8 for a travel stop. The desired movement option can then be selected by rotating the rotary wheel 10 and the confirmation command can be given again by advancing the hand 6. This enables the desired and preselected movement to be initiated.
While the traversing movement is being carried out, it is conceivable that a further desired traversing movement is selected in the display 8 and selected again by confirmation by advancing the hand 6.
In particular, it can be provided that the movement is carried out only as long as the hand 6 is in one of the sensor areas 18, 19 and that the movement is stopped when the rotary wheel 10 is released.
In the context of the present invention, the evaluation of the respective sensor signals of a sensor element is connected to the controller 3 of the electrical machine. The controller 3 implements the selected parameters, options, control commands by activating the respective actuators of the machine 2.
FIG. 7 shows a further embodiment of the rotary wheel 10, which may be independent of its own, again using the same reference numerals or component designations for the same parts as in the preceding FIGS. 1 to 6. In order to avoid unnecessary repetitions, reference is made to the detailed description in the preceding FIGS. 1 to 6.
20/39
N2017 / 28000-AT-00
Furthermore, as shown in FIG. 7, provision can also be made for an additional sensor area 31 with a corresponding sensor element 32 to be formed on an end face 30 of the rotary wheel 10. Such an additional sensor area 31 can also be used to enter control commands, in particular a stop command. The additional sensor element 32 can in particular be a pressure-sensitive sensor element.
In addition, it can be provided that further actuating sections or corresponding sensor areas are formed on the rotary wheel 10.
As can be seen in FIG. 8, the lateral surface 11 of the rotary wheel 10 can be divided into at least two actuating sections 14, 15 with different surface structuring 17. FIG. 8a shows an oblique view of a rotary wheel 10 which has elevations 26 in the gripping area 29 in the form of knobs which are regularly distributed in the circumferential direction. The gripping area 29 can be designed as a separate, additional actuating section and / or sensor area. Furthermore, a first actuation section 14 can be seen in FIG. 8 a, which has surface depressions 17 in the form of grooves 27 running in the circumferential direction. The grooves have different depths in the direction of the axis of rotation. The second actuating section 15 of the rotary wheel 10 is arranged closest to the control element body 7 in the direction of the axis of rotation 12 and is in the form of a disk with a rounded shoulder. The surface structures 17 of the second actuating section 15 are designed as oval or eye-shaped depressions 27 on the rounding of the shoulder, and a smooth surface of the lateral surface 11 of this actuating section 15 running parallel to the axis of rotation 12.
The example in FIG. 8 is intended to illustrate the multitude of design options. Furthermore, it can be clearly seen in FIG. 8 b that the local mean mean value 13 depends on the basic contour of the rotary wheel or individual actuation sections.
21/39
N2017 / 28000-AT-00
9 shows some examples of different basic contours of the rotary wheel 10. The basic contour here essentially corresponds to the “envelope” of the lateral surface 11 along its axis of rotation 12. The basic contour of the rotary wheel 10 is preferably rotationally symmetrical about the axis of rotation 12.
It can be seen particularly well from FIGS. 8 and 9 that at least one of the actuation sections 14, 15 along the axis of rotation 12 can have different local mean diameters 13. The actuating sections 14, 15 can in particular have continuous and / or discontinuously increasing and / or decreasing local diameter mean values 13. The rotary wheel 10 can thus have one or more shoulders and / or steps and / or transitions running (see FIG. 9 a-h). This increases the manageability of the rotary wheel 10 by the machine operator 5. It can be advantageous if any shoulders and / or steps and / or the ends of a course limit the respective actuating sections 14, 15 in the direction of the axis of rotation 12. As shown schematically in FIGS. 8 and 9, a basic contour can be composed of a plurality of geometrically simple bodies, such as disks, cones, or spherical segments, and specify the outer shape of the rotary wheel 10.
The rotary wheel 10 therefore does not necessarily have to be understood as “in one piece”, but can also be composed of several sections. This can offer manufacturing advantages. In such a case, however, the subsections should be connected to a rotary wheel 10 via a common axis of rotation 25 and to the control element 7.
Local mean diameter values 13 of the lateral surface 11 between 20 mm and 80 mm, in particular between 35 mm and 60 mm, preferably between 40 mm and 50 mm, have proven to be particularly easy to grasp by the machine operator 5.
Furthermore, as shown in FIG. 7, the hand 6 of the machine operator 5 can also grip the rotary wheel 10 on the peripheral region of a shoulder. If the second sensor area 19 extends over the end face and the peripheral area of a shoulder, this leads to the second sensor area 19 being activated.
22/39
N2017 / 28000-AT-00
According to the exemplary embodiment in FIG. 7, it is also conceivable that a third actuating section 16 or third sensor area 20 is formed in the peripheral area of a shoulder, which is detected by a third sensor element 23. In such an embodiment, touching the end face of a paragraph and touching the peripheral area of this paragraph can trigger a different command. For example, it is also conceivable that when using a third sensor area 20, the hand 6 of the machine operator 5 is positioned as shown in FIGS. 5 or 6 and only one or more fingers are placed on the third actuation section 16 or third sensor area 20 trigger a specific command.
The above-mentioned exemplary embodiments of the figure descriptions 1 to 7 can be applied analogously to the exemplary embodiments of different geometries of the rotary wheel 10, as shown in FIGS. 8 and 9.
According to a development, it is possible for the surface structuring 17 of at least one of the actuating sections 14, 15, 16 to have round and / or elongate elevations 26, such as e.g. Ridges, knobs, pyramids, scales and / or depressions 27, such as e.g. Grooves, grooves, dents, honeycombs, dimples, dimples compared to the local average diameter 13 of the lateral surface 11. The position of the hand 6 or the fingers on the lateral surface 11, and thus the at least two actuating sections 14, 15, 16, can thus be perceived immediately by the machine operator 5. The advantage here is that the machine operator 5 “feels” the position of his hand 6 or finger as soon as the rotary wheel 10 is gripped. This enables a clear assignment of the surface structures 17 to commands to the controller 3 of the machine 2.
Some examples of possible surface structures 17 are shown in FIGS. 10a-k.
In the context of this invention, the term surface structuring 17 encompasses the nature of the surface, in particular the lateral surface 11, of the rotary wheel 10
23/39
N2017 / 28000-AT-00
Surface structuring can be understood. Different surface roughness can already be perceived as different surface structures 17 by a machine operator 5. However, it is particularly preferred if the surface structures 17 of the at least two actuating sections 14, 15, 16 are clearly distinguishable from one another.
A combination of different elevations 26 and / or depressions 27 and / or surface roughnesses are also conceivable for the design of the surface structures 17 of at least two actuating sections 14, 15, 16.
In particular, provision can be made for elongated elevations 26 and / or depressions 27 to have a ratio of a greater extent to a shorter extent of the elevations 26 or the depressions 27 on the lateral surface 11 of greater than 1.5, preferably greater than 5. This can be seen particularly well from the examples in FIGS. 10a and 10c-i. It can also be provided that the surface structuring 17 of at least one of the actuating sections 14, 15 is formed symmetrically over at least one direction, preferably in the circumferential direction, over the lateral surface of the respective actuating section.
In particular, surface structures 17 can be designed to run continuously in the circumferential direction 24 (compare FIGS. 10 a and h). Likewise, the surface structures 17 can be designed to be inclined in the direction of the axis of rotation 12 or at an angle to the axis of rotation 12 (see in particular FIG. 1 Oh). Furthermore, the surface structuring 17, in particular elevations 26 and / or depressions 27, can be offset with respect to one another in at least one direction (see, for example, FIGS. 10e, k). Such a surface structuring 17 can e.g. represent a corrugated or nubbed surface.
It can also be seen from FIGS. 8 and 10 that the surface structuring 17 of at least one of the actuating sections 14, 15 is formed uniformly over the lateral surface 11 of the respective actuating section 14, 15
24/39
N2017 / 28000-AT-00 can. The uniform and / or symmetrical design of the surface structuring 17 can offer advantages in terms of production technology and can be implemented inexpensively.
According to a further development, it can be provided that the surface structuring 17 of at least one of the actuating sections 14, 15 is formed irregularly over the lateral surface 11 of the respective actuating section 14, 15. Especially with stochastic processing methods such as Sandblasting or shot peening, or machining processes with an undefined cutting edge, e.g. Grinding or brushing can make irregular surface structuring 17 relatively simple and therefore cost-effective. Such methods often do not form sharply defined interfaces at the edge areas.
According to an advantageous development, it can be provided that the surface structuring 17 of at least one of the actuating sections 14, 15 has a ratio of the deviation of the largest elevation 26 and / or the lowest depression 27 of the lateral surface 11 in the normal direction to the axis of rotation 12 to the local mean diameter 13 of greater than 0.001, preferably 0.005, particularly preferably greater than 0.01. As shown in FIGS. 8, 9 and 10, the local mean mean values 13 can easily be determined according to the position along the axis of rotation 12. Such minimum deviations of the elevations 26 and / or depressions 27 are particularly advantageous for a sufficiently good perceptibility of the machine operator 5. The height of the elevations 26 or the depth of the depressions 27 can also be designed such that they represent a suitable receptacle for the fingers of the machine operator 5 between the elevations 26 or in the depressions 27 (compare, for example,
Fig.8a).
In particular, it can be advantageous if the outer surface 11 of at least one of the actuating sections 14, 15 consists predominantly of metal. The high mechanical resistance and good machinability of metals make a robust design of the rotary wheel 10 particularly advantageous for this. Furthermore, the sensor elements 21, 22 assigned to the sensor regions 18, 19 can
25/39
N2017 / 28000-AT-00 can be designed, for example, as sensor elements for electrical conductivity measurement.
In an advantageous development, it can be provided that surface structuring 17 of at least one of the actuating sections 14, 15 has at least partially a second material, preferably plastic. The application or introduction of a second material as surface structures 17 can increase the security against slipping of the hand 6 or the fingers of the machine operator 5. In the event that the rotary wheel 10 is predominantly made of metal, it offers a second material, and in particular a dielectric material such as e.g. Plastic, the advantage that one or more sensor elements 21, 22 assigned to the actuating sections 14, 15 or sensor areas 18, 19 can be designed as capacitive sensors. Such capacitive sensors can e.g. be designed as proximity sensors, displacement sensors, acceleration sensors or also pressure sensors. The variety of possible commands to a controller 3 of the machine 2 is thus significantly increased.
It can further be provided that at least one actuating section 14, 15 has a pressure-sensitive sensor element. As can be seen from the preceding description, the majority of the parameter selection and machine commands can be carried out by means of the rotary wheel 10. However, it has proven to be particularly advantageous that a pressure-sensitive sensor element is provided for signaling an exceptional state, in relation to the controller 3 of the machine. In the event of a dangerous or exceptional situation, the machine operator 5 can trigger a “stop command” to the controller 3 of the machine 2 by exerting a force. An accidental triggering or actuation of this "stop command" is prevented by the above-mentioned "normal operating mode", e.g. Rotational movement of the rotary wheel 10 and / or displacement of the fingers of the machine operator 5 efficiently avoided. The sensor region 18, 19 of a pressure-sensitive sensor element can preferably lie on the lateral surface 11 in the circumferential direction 24.
However, a configuration is also conceivable, according to which it can be provided that a pressure-sensitive sensor element 23, 32 is arranged in such a way that
26/39
N2017 / 28000-AT-00 whose sensor area 20, 31 is aligned essentially in the direction of the axis of rotation 12. In addition to the above-mentioned embodiment, a movement in the direction of the rotation axis 12 with a force effect on the pressure-sensitive sensor element 23, 32 represents a large, and therefore clear, difference from the “normal operating mode”. The machine operator 5 can thus clearly be an exceptional situation differ from the "normal mode of operation". The application of force in the direction of the axis of rotation 12 can even take place in the limit case by the machine operator 5 striking the rotary wheel 10. A short reaction time of the machine operator 5 is made possible, which increases the safety during operation. A pressure-sensitive sensor element is preferred as e.g. Additional, fourth sensor element 32 is arranged on the end face of the gripping area 29.
In an alternative embodiment, the rotary wheel 10 on the control element body be mounted displaceably in the direction of the axis of rotation 12 and a switching or sensor element 28 may be formed, which is provided as a function of the displacement of the rotary wheel 10 along its axis of rotation 12 for signaling or triggering a quick stop or emergency stop command. The switching or sensor element 28 is indicated in FIGS. 3 to 7 and represents a special embodiment. In this development it is advantageous that the command input for an exceptional situation in the controller 3 of the machine 2 is decoupled from the at least two actuating sections 14, 15 on the lateral surface 11. Due to the compact design of the rotary wheel 10, which only has a common axis of rotation 25, the machine operator 5 can very easily move the rotary wheel 10 along its axis of rotation 12. The position of the force application on the rotary wheel 10 is therefore of secondary importance for the displacement. In the borderline case, this can even be done by the machine operator 5 striking the rotary wheel 10 so that a shift in the direction of the axis of rotation 12 is initiated. The switching or sensor element 28, which is provided for signaling a “quick stop” or “emergency stop command” to the controller 3 of the machine 2, can be installed very simply and robustly in the operating element 4 or operating element body 7. This represents an inexpensive and very safe design. It can also be provided that the rotary wheel 10
27/39
N2017 / 28000-AT-00 is locked in position after the displacement along the axis of rotation 12. This blocks a rotary movement of the rotary wheel 10 or an input of commands by moving the hand 6 or the fingers of the machine operator 5. In this case, the rotary wheel 10 can only be released after the “quick stop” or “emergency stop” command has been acknowledged.
The exemplary embodiments show possible design variants, it being noted at this point that the invention is not limited to the specially illustrated design variants of the same, but rather also various combinations of the individual design variants with one another are possible and this variation possibility is based on the teaching of technical action through the present invention Ability of the specialist working in this technical field.
The scope of protection is determined by the claims. However, the description and drawings are to be used to interpret the claims. Individual features or combinations of features from the different exemplary embodiments shown and described can represent independent inventive solutions. The object on which the independent inventive solutions are based can be found in the description.
All information on value ranges in the objective description is to be understood so that it includes any and all sub-areas, e.g. the information 1 to 10 is to be understood so that all sub-areas, starting from the lower limit 1 and the upper limit 10, are included, i.e. all sections start with a lower limit of 1 or greater and end with an upper limit of 10 or less, e.g. 1 to 1.7, or 3.2 to 8.1, or 5.5 to 10.
For the sake of order, it should finally be pointed out that, for a better understanding of the structure, elements have sometimes been shown to scale and / or enlarged and / or reduced.
