·· · · · · · · · -1 -

The invention relates to a portable operating and monitoring device for an industrial control device of a machine, a robot or a technical process, as specified in claim 1.

DE 100 23 199 A1 of the applicant discloses a handheld operating device for robots or other electrical machines with a plurality of programming or operating elements for programming or controlling movement sequences or operating states. This hand-held operating device also includes a safety switching device which is to be used or operated in combination with the programming or operating elements of the manual operating device in order to be able to carry out safety-critical actions. The programming or operating elements of this handheld terminal are formed by buttons, switches, knobs or control levers. Furthermore, this known hand-held operating device has a display, in particular an LCD display, for the visualization of process or input data. Individual programming or operating elements are associated with optical signal sources, e.g. with LEDs, provided to signal their respective switching state. In order to be able to manage more complex, technical processes, a large number of operating elements are required on this manual operating device, which makes it difficult to understand the various functions. In addition, the large number of controls requires a relatively large housing, whereby the handling or the workflow is difficult for the user of such a handheld terminal.

From the document WO 03/001393 A2, which is likewise based on the applicant, further variants of portable devices for visualizing process data of a machine, a robot or a technical process are described, wherein these portable devices or hand-held operating devices are also used for operating or programming said automation devices are suitable. N2006 / 19800 Μ · ··· # ···· # To be able to keep the number of input elements to be executed in hardware low, and thus to achieve compact housing shapes as possible. Both embodiments are provided for support and support on the forearm of a user. According to the first embodiment, in a first end portion of the housing, a bead-like thickening is provided, which is provided for support in the palm of an operator, this thickening being held between the ball of the thumb and the fingers. This portable device has two symmetrically arranged to the longitudinal central axis of the housing enabling button, whereby an operation of the portable device for both left and right-handed is possible after a left thumb and a right thumb assigned enabling button is executed on the housing. These two enabling buttons are integrated in the bead-like thickened holding or gripping section of the housing and are functionally connected in parallel in terms of their function as enabling buttons for the execution of potentially safety-critical control functions and thus can be used selectively. In this bead-like, resting in the palm holding or handle portion is also a third safety switching device, in particular a combined consent and panic stop switch is formed, which is actuated by the fingers of that hand, which holds the housing. The housing of this portable device is approximately the size of a DIN A4 sheet, whereby the second hand of the user for operating the formed on the top, large-scale touch screen is required. For operator operations via this portable device, therefore, a hand for holding the housing is absolutely necessary, while the second hand can actuate the input elements formed on the upper side of the portable device in the form of so-called soft keys or in the manner of electromechanical input elements.

According to a further embodiment of a generic, portable operating and monitoring device described in this document, the housing is essentially circular or disk-shaped in plan view. On the underside of the housing a stepped handle portion is formed, which allows a holding of the housing with the left or alternatively with the right hand of a user. Also, this housing is provided for support on the forearm of a user because of its dimensions and mass, after having approximately a diameter corresponding to the longitudinal side of a DIN A4 sheet. Two safety switching devices N2006 / 19800 9t ···· 99 · 9 ··· -3 are installed in this housing, wherein the first safety switching device is provided for operation by the left-hander and the second, for the first symmetrically arranged safety switching device for actuation by a right-handed person is provided. At the top of the housing, a safety switching device in the manner of an emergency stop switch is also formed. Here, too, a hand is used to hold the housing and also to occasionally required actuation of one of the two running as a safety switch safety switching devices. In order to be able to carry out potentially dangerous actions, at least one of the two enabling buttons must be actuated. The user's second hand is required to operate the input elements formed on the top of the housing.

Furthermore, a portable operating and monitoring device is known from the prior art, which likewise rests on the forearm of the hand during an operating procedure, with which the operating and monitoring device is held. From the bottom of this portable electronic terminal is a handle part, which is rotatably mounted relative to the housing about an axis perpendicular to the display surface extending axis. In this structurally independent handle an enabling button is placed centrally and integrated fixed that it can be operated if necessary via the fingers of the operator. The pivotability of the handle allows adaptation of the operating and monitoring device to right and left-handers. The articulated connection between the underside of the housing and the handle part is particularly solid perform to prevent damage to the pivot bearing or the housing bottom, even if the portable device falls to the ground, as can not be excluded under industrial service operations. Consequently, the rotatable connection between the Griftteil and the housing is to be carried out as stably as possible, whereby the weight of the portable device increases and the ease of use is impaired. In particular, prolonged work can lead relatively quickly to cramping or fatigue of the housing holding hand.

The present invention has for its object to provide a portable control and monitoring device of the type mentioned, which allows the most fatigue-free working even when longer-lasting control and monitoring activities are executed. Another task is a possible N2006 / 19800

•••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••• achievable accident safety for persons or this is at the expense of availability or reliability of a technical equipment to be operated.

The object of the invention is achieved by a portable control and monitoring device according to the features of claim 1. It is advantageous that the safety switching device can be adjusted at any time in relation to the holding or gripping portion of the housing. This ensures that the safety switching device can meet the different requirements of different operators in terms of ergonomic positioning and an instant accessibility with spontaneous pressurization. By individually selectable positioning ability of the safety switching device or its actuating surface relative to the holding or handle portion of the housing so on the one hand a high operating ergonomics and on the other a very short-term or possible delay-free operation of the safety switch allows. Especially for those operating operations in which the safety switching device acts as an enabling switch, a long-term fatigue-free working with the portable operating and monitoring device is achieved after the actuating surface can be positioned as low as possible, so that cramping the hand or the user's fingers are kept behind. Especially with relatively long-lasting programming operations for movements of industrial robots of increased ease of use and equally increased operating safety are of particular importance. Of particular advantage is further that this allows a good adaptation to different sized hands or to different finger lengths, which in turn improves the ergonomics of the control and monitoring device and above all provides a basis for a long-term fatigue-free, highly concentrated work is created. Fatigue-free working is also facilitated by the fact that the portable operating and monitoring device can be changed by the operator from time to time in the holding position to some extent. In particular, a more or less strong engagement behind the holding or grip portion is possible and can be carried out in each of these time-varying holding positions an optimal tracking of the safety switching device. Of particular advantage is further that the housing of the operating and monitoring device according to the invention can be made very compact. In particular, within the housing or N2006 / 19800 ···· • ♦ • ··· • ················································································· -5-saved within the holding or GrifFabschnittes volume, after only a single safety switching device is required, but which can still be optimally achieved or operated by different operators. Furthermore, this cost savings can be achieved after the cost of several, mechanically relatively expensive safety switching devices and for special electronic evaluation circuits for safety-correct linking and mutual locking of multiple safety switching devices can be saved. The solution according to the invention thus also enables the formation of particularly compact housing and the creation of the most lightweight operating and monitoring devices, after only one safety switching device, in particular only one enabling button is required, which can be positioned as desired by different operators to the best individual access to receive. Of particular advantage further is that the solution according to the invention can achieve a high degree of robustness, after the handle part can represent a rigid or integrated portion of the housing and thus either breakage or massive and therefore heavy fasteners or bearing body between the movable handle and the housing can be left out.

Of particular advantage is an embodiment according to claim 2, since the operating and monitoring device can thereby be operated optimally both for left-handers, as well as for right-handed. In addition, a particularly slim holding or grip portion can be created on the housing, which allows a relatively safe fall holding the operating and monitoring device after such a holding or grip portion can be easily grasped and held by the operator. Of particular advantage is further that on the control and monitoring device no alterations or no adaptations to the structure are required to adjust the position of the safety switching device or its actuating surface to the respective ideas of the operator, in particular to the gripping position or on the size of his hand can. After the positioning device for the safety switching device or for their actuating surface is manually adjustable, a quick, tool-free adjustment can be made at any time, so that the ease of use of the portable operating and monitoring device is high and always optimal relative position of the actuating surface of the safety switching device relative to the fingers or the fingertips of the housing holding hand can be made. The off-center positionability of the safety switching device with respect to the longitudinal central axis N2006 / 19800 -6- allows an optimized actuation of the safety switching device by means of the fingertips or the fingertips both in an operation by a left-hander and in an operation by a right-handed person.

The measures according to claim 3 ensures that only a relatively small portion of the holding or GrifFabschnittes is executed on the housing as an actuating surface for the safety switching device. As a result, sufficiently large sections of the holding or GrifFabschnittes remain relentless or rigid, so that a secure or firm gripping the operating and monitoring device is possible. On the other hand, it is ensured by this size and shape limitation of the actuating surface, that the safety switching device is only possible temporarily actuated, and only if this is intended or intended by the operator. In particular, it is avoided by this limitation of the actuating surface that occurs by the ordinary holding or easy gripping the holding or gripping part unconscious or unintentional operation of the safety switching device. In particular, due to the limitation of the available actuating surface by means of the fingertips or fingertips, the operator must actively act on the actuating surface with sufficient actuating force, so that he always gives a conscious consent to a potentially dangerous control command.

Another advantage is the embodiment according to claim 4, as this unconscious actuation of the safety switching device, in particular the enabling button can be avoided after the actuating surface of the safety switching device is operated only via the fingertips or the fingertips of that hand, which also for holding the housing is used. A habituation-related or unconscious activation of the safety switching device is thus avoided. In addition, this ensures that the operator can grab reflexively in panic situations and thus can immediately transfer the safety switching device in a panic-stop state, which leads to an immediate halt of potentially dangerous movements or machine actions. In addition, a safety switching device can thereby be installed in which the pressure point or the required actuating force for the transition from the consent position to the panic stop position is relatively N2006 / 19800 m m.

As a result, a particularly comfortable operating and monitoring device is provided, which achieves a high level of operating convenience, especially when carrying out standard operating operations, and at the same time fulfills high safety requirements. In addition, the actuating surface of the safety switching device can be converted by a partially reflex-related, tighter grab on the holding or gripping portion in the third switching stage, in particular in a panic stop switching state, in which abzusichemden motion or machine functions terminated immediately or be switched off. This one-hand operation of the operating and monitoring device thus results in comfort improvements, without resulting in security losses.

Another advantage is an embodiment according to claim 6, since a relatively large-scale display can be formed, which allows a clear presentation of the respective information or data and favors a rapid acquisition of process-relevant data by the user. In addition, the comparatively slender, preferably integrally adjoining, holding or gripping section of this operating and monitoring device offers a high level of security against unintentional crashes of the operating and monitoring device after the relatively slender, preferably approximately rod-shaped, holding or gripping part gripped securely can be. Of particular advantage is further that individual or some input elements on the holding or gripping portion to perform motion functions or to initiate special machine functions are designed so that a real one-handed operation is possible after the case can be held with one hand, if necessary simultaneously with the fingers of this hand, the safety switching device can be actuated and also arranged with the thumb of this hand at the top of the holding or handle portion input elements, such as Buttons, switches or knobs, can be operated. N2006 / 19800

Of particular advantage is an embodiment according to claim 7, as a result of a robust positioning is provided, which can easily withstand high loads. In addition, this allows a smooth repositioning of the safety switching device. In particular, by means of such a bearing device, the friction or movement resistance occurring in the execution of a repositioning of the safety switching device can be kept low.

Another advantage is an embodiment according to claim 8 or 9, since thus a slender, for example, rod-shaped holding or grip portion with integrated, variably positionable safety switching device can be created, the safety switching device in a simple manner between a left to the longitudinal central axis position and a Right to the longitudinal center axis lying position and vice versa can be adjusted so that in a simple and reliable way an ergonomic operation for left and right handed is achieved.

By the measures according to claim 12, both different inclinations of the actuating surface can be adjusted, as well as different distancing to the longitudinal central axis of the holding or handle portion can be achieved. This achieves a favorable adaptation to different sizes of hands. The different inclinations of the actuating surface thereby change automatically depending on the distance of the actuating surface relative to the longitudinal central axis of the holding or gripping part, in particular as a function of the angular position of the drum-like housing part. This results in N2006 / 19800 ······························································································································································································································· a further improved ergonomics and handling of the operating and monitoring device with at the same time as simple and robust construction.

Another advantage is also an embodiment according to claim 13, as a relatively extensive adjustment of the safety switching device is thereby made possible and a large adjustment can be created, whereby the most diverse needs and hand sizes can be optimally taken into account.

The advantage here is an embodiment according to claim 14, characterized in that the safety switching device can be predominantly integrated into the holding or handle portion, so that there are no disturbing elements on the outside of the holding or handle portion.

The measures according to claim 15 ensure that after a readjustment of the positioning device, the tightness of the housing remains ensured, so that the electrical or electronic components contained therein are reliably protected from damage. In addition, no modifications or tools are required to ensure the required tightness of the housing against foreign bodies, dirt or the like. After a change in the position of the safety switching device.

Also advantageous are the measures according to claim 16, as characterized by a user-selected relative position can be sufficiently stable secured to prevent undesirable adjustment movements. In particular, this ensures that an adjustment made by the operator of the safety switching device is reliably maintained. As a result, an unfavorable, searching palpation of the actuating surface of the safety switching device by means of the fingers can be avoided in most cases.

By the measures according to claim 17, a two-dimensional adjustment movement for the safety switching device can be carried out without difficulty, without expensive guides or the like. Are required. In addition, this support plate for the safety switching device ensures that the inside of the housing and the holding or gripping portion is protected from foreign bodies, dirt or the like. In particular, N2006 / 19800, the holding plate is a support function and also a sealing function, wherein in the event that the Relatiwerschiebbarkeit between the holding plate and the housing portion is two-dimensional, allows optimal adjustment of the actuating surface of the safety switching device relative to the fingertips or fingertips of a user is.

The measures according to claim 18 ensure that the portable operating and monitoring device can also be used under industrial or relatively harsh conditions without having to fear any functional impairments or failures.

Another advantage is also an embodiment according to claim 19, characterized in that a convexly convex in cross-section underside of the holding or handle portion is created, which is advantageous for ergonomic holding the portable operating and monitoring device. In addition, an accessible from the bottom of the housing safety switching device can be easily installed in the holding or handle portion, depending on a left-side positioning or a right-side positioning of the safety switching device optimized operation for right-handed or left-handed is achieved. The flattened in comparison to the arcuate underside or largely ebenflächige top of the holding or handle portion can be used in an advantageous manner for the arrangement of input elements, which input elements then operated and operated one hand and ergonomically favorable by the thumb on the holding or gripping portion receiving hand can be.

Another advantage is also an embodiment according to claim 20, characterized in that an axial rotation for the housing or the stabformigen holding or handle portion is created. This support element can be supported on the back of the hand, so that unwanted rotations of the control and monitoring device are also prevented around its longitudinal axis when the hand holding the housing less tightly grabbing.

An advantage of this is a further development according to claim 21, since this provides an axial rotation lock for the housing, this rotation lock both in an operation by left-handers as well as in an operation by a Rechtshän- N2006 / 19800 ··· ···· Μ It is possible to make corresponding use of this operating and monitoring device especially left-handers in terms of ergonomics not disadvantaged.

Furthermore, individual features or combinations of features from the different exemplary embodiments shown and described can also represent independent, inventive or inventive solutions.

FIGS. 1 to 5 illustrate an embodiment of a portable or mobile operating and monitoring device 1. This operating and monitoring device 1 serves at least for monitoring the operations of industrial manipulators or robots, automated machines, such as e.g. Machine tools, special purpose machines, conveyors, N2006 / 19800 ·· ·· ♦ · ♦ · · · · · · · · · · · ·

II deranlagen, cranes or other technical equipment with which technical processes are carried out fully automatically, semi-automatically or manually controlled. In addition to the visualization of process or system data, the operating and monitoring device 1 preferably also serves to operate or influence the aforementioned machines or process sequences. The operating and monitoring device 1 thus represents a visualization or observation device and / or operating device. Alternatively or in combination for at least one of the aforementioned uses, the operating and monitoring device 1 also for programming the processes of electrical actuators or sensors serve provided machines or robots. In such a programming mode, for example, a so-called "tea-ching" of machines or robots can be made.

The control and monitoring device 1 is to be operated by hand and sized in size and weight so that it is easily portable by a user to different locations. That is, an operation and observation device 1 can also be assigned to different, locally mutually distanced machines or robots and the user can, for example, motion sequences or the like. By his freedom of movement with the operating and monitoring device 1 optimally-hen.

The operating and monitoring device 1 comprises at least one output device 2, at least for visualization of process data of a machine, a robot or a technical process. The output device 2 comprises at least one optical output element and optionally additional acoustic output elements, such as buzzer,

Speakers or the like. In addition to or as an alternative to the process data, input data or input menus and screen masks can also be displayed via the optical output device 2. Individual optical output devices 2 can also be controlled by optical signal sources, e.g. be formed by light emitting diodes.

Furthermore, the operating and monitoring device 1 comprises at least one input device 3, via which individual operating functions of at least the operating and monitoring device 1 can be influenced or selected. Preferably, the input device 3 is also used for operating a machine or a robot or for dispensing N2006 / 19800 ··· ···· ········································································· · · · · · · · · · · · · · · -14-

Control commands to such machines. By means of the input device 3, therefore, internal processes of the operating and monitoring device 1 and / or an associated machine can be changed and data can be entered, retrieved and / or changed.

The operating and monitoring device 1 can also have a combined output and input device 2, 3 in the manner of a touch-sensitive screen 4. This touch-sensitive screen 4 of the operating and monitoring device 1 represents a so-called touch screen 5, in which the output and input device 2.3 are functionally combined or structurally superimposed. The touch-sensitive screen 4 of the operating and monitoring device 1 extends over subsections of an outer surface, in particular an upper side 6 of a housing 7 of the operating and monitoring device 1. By means of this touch screen 5, as is known per se, graphics, symbols , Characters and the like. Issued and made via actuation of the touch-sensitive surface with a finger or a pen-shaped input device corresponding inputs or various actions are initiated. Through the use of such a touch screen 5, the number of operating elements, such as e.g. Button, switch, slider, knob or the like. Can be significantly reduced and is an intuitive operation of the control and monitoring device 1 allows. In addition, the usual variety of keys can be reduced and is thereby achieved a better overview and more comfortable operation. In the case of the operating and monitoring device 1, electromechanical input elements 8 are then advantageously formed only for the most frequently used functions or for functions in which a so-called tactile feedback is advantageous. Such functions are, above all, motion functions or switch-on and switch-off functions or functions for the incremental or decremental change of parameters. These input elements 8 are preferably formed by a membrane keypad 9 with tactile feedback of the switching process or by input elements 8 with noticeable and / or audible recognizability of the switching point.

In addition to these input elements 8 with clearly recognizable switching function, the operating and monitoring device 1 can also be operated by a user of the operating and monitoring device 1 to be moved control element 10 in the manner of a control lever, joystick 11, rotary potentiometer, a space mouse, an electronic handwheel or N2006 / 19800 ························································································································································································································· exhibit. With such a control element 10, especially the directions and / or speeds of movements of a machine or a robot to be controlled can be specified and executed comfortably and intuitively.

The operating and monitoring device 1 comprises in an ideal manner a single safety switching device 12, in particular an enabling button, which is mounted on or in the housing 7 of the operating and monitoring device 1 and by a user, especially in the execution of safety-critical or Potentially dangerous operation sequences or operating state changes simultaneously with the input elements 8 and the programming or operating elements 10 of the input device 3 is to be operated in a predetermined manner in order to achieve an approval or a control-technical approval for the execution of this potentially critical function. This safety switching device 12, which is usually designed as an enabling button 13, is used to avoid unintentional or unforeseen delivery of control commands for a machine, a robot or a technical process. The safety switching device 12 is for use in combination with input elements 8 or programming elements 10, such as, for example, Joystick, button or switch, provided, with an activation of a potentially critical movement sequence or a transfer to a potentially hazardous operating condition is only possible under normal operation of the safety switching device 12. In particular, for the execution of safety-critical motion sequences or in the intended initiation of operating conditions in which there is an increased risk of accidents for persons or increased risk of damage to the machine or the workpiece, this safety switching device 12 in combination with the actual input elements 8 for triggering or initiation of the respective Function to operate. The safety switching device 12 is integrated into the electrical control of the machine or of the robot in such a manner that the input elements 8 to be covered or programming or operating elements 10 are activated effectively only when the consent position is taken on the safety switching device 12. The safety switching device 12 is therefore often referred to in practice as the enabling switch 13. N2006 / 19800

The safety switching device 12 or the enabling switch 13 has at least one switching stage, preferably two switching stages, wherein the respective switching stages are executed in a tactile function. That an assertion position on the safety switching device 12 actively maintained by a user will only be maintained during the active actuation by the user in the corresponding shift position. The safety switching device 12 therefore has no latching or permanently ingestible position, except for the unactivated resting or starting position. In the rest or starting position, the safety switching device 12 assumes the first switching stage, in which an execution of safety-critical control commands is not possible. In a second switching position of the safety switching device 12, the delivery of safety-critical control commands is made possible only while the user holds the safety switching device 12 in this so-called approval state. Preferably, the safety switching device 12 may also have a third switching stage, namely a so-called panic switching state in which a machine to be controlled is converted into a safety state or in which a safety shutdown is performed. When taking this third switching state, at least all critical movement sequences or operating states of the machine or of the robot are stopped immediately. This third switching stage is usually shortly before or during an emergency situation, e.g. an imminent damage to property or an accident in which the operator's hands or fingers tend to cramp. If the user is disturbed by a suddenly occurring dangerous situation, the latter either takes his hand off the safety switching device 12 and thus transfers it to the idle state or a spasmodic increase in the actuation pressure on the safety switching device 12 occurs and this is thereby converted into the panic state, in which as well shutdown or shutdown of the machine or the robot takes place.

Housed in the housing 7 of the operating and monitoring device 1 is an electronic control device with which the possible operating functions of at least the operating and monitoring device 1 are implemented. This control device comprises at least one software-controlled microcomputer, in particular a powerful and energy-efficient microprocessor for performing arithmetic operations, for evaluating data and for controlling functional sequences of the operating and monitoring device 1 and / or a machine to be controlled. N2006 / 19800

The operating and monitoring device 1 has at least one communication interface 14 to an external control device for a machine or a robot and / or to a host computer. This at least one communication interface 14 is preferably formed by a standardized interface, which is suitable for connection to common data bus systems and, for example, is realized by an Ethernet, a CAN, a serial or an Internet communication interface or other wired interface. Alternatively or in combination with a wired communication interface 14, it is of course also possible to form wireless communication interfaces 14, in particular in the form of radio interfaces and / or infrared interfaces on the operating and monitoring device 1. In an advantageous manner, the communication interface 14 can also be formed by a so-called Bluetooth interface, via which, within a restricted communication area, a data connection to peripheral electronic components, such as e.g. a keyboard, a mouse, a printer or other processing unit can be constructed.

The operating and monitoring device 1 may also include an emergency stop switch 15, the actuating member 16 protrudes from the housing 7 and projects from the housing surface. Upon actuation of this emergency stop switch 15, a machine to be controlled is placed in the emergency stop state, in which at least some movements are stopped or at least some areas of the machine to be controlled are de-energized. The emergency stop switch 15 is locking and preferably designed with two circuits to achieve a high switching reliability or a reliable shutdown of equipment or machine parts. This emergency stop switch 15 is arranged in an easily accessible area, for example in a front or in a corner region of the housing 7. Of course, it is also possible to let the actuator 16 of the emergency stop switch 15 from the user facing during operation facing top 6 of the housing 7.

The housing 7 is formed in a top view of FIG. 1 is substantially T- or club-shaped, wherein it has a relatively slender holding or gripping portion 17 for gripping by a user. At this relatively narrow holding or gripping portion 17 of the housing 7 closes a comparatively wider display section 18 N2006 / 19800 -18- •···· • · ♦ · ··· • • • • • • • • • • • • • «··· • • • • • • • • • • • • ·····································. In this opposite the holding or gripping portion 17 widened display section 18, the optical output device 2, in particular the display of the control and monitoring device 1 is arranged. In the holding or gripping portion 17, a plurality of input elements 8 are placed, wherein at least one input element 8 is provided in the holding or gripping portion 17 of the housing 7 for performing potentially hazardous or abzusichemder functions and thus to operate in combination with the safety switching device 12. The holding or gripping portion 17 is preferably formed by a housing portion which constitutes an integral portion of the housing 7 and is immovable or rigid relative to the adjoining housing portions. Preferably, the display section 18 and the holding or gripping portion 17 are made in one piece and form these two different width sections in total the housing 7 of the control and monitoring device 1 from.
