BACKGROUND OF THE INVENTION

The invention relates to a device and a method for operating a machine equipped with a handling device, in particular an injection moulding machine.

Injection moulding machines with a linear robot as handling device are known, in which on the one hand a stationary operating device for the injection moulding machine and a mobile operating device for the linear robot are provided. The configuration and operation of the injection moulding machine and the configuration and operation of the linear robot run via a control arrangement. The configuration and the operation of the linear robot takes place on the screen of the stationary operating device of the injection moulding machine and on the screen of the mobile operating device of the linear robot with identical presentation of the screen pages and with identical functionality.

From DE 10 2005 020 775 A1 (see FIG. 1 therein), a handling device is known, designated therein as a robot, which has a stationary operating device in the form of a central monitoring and control device, which has input and output means. Input means can be keys, switches and levers. A screen is provided as output means. The central monitoring and control device is connected via a connecting cable with a mobile operating device, which is also designated as a manual operating device. The mobile operating device or respectively the manual operating device has an input field with input keys. Furthermore, it has a small display, in which words or single characters can be displayed. In order to also be able to carry out more extensive communication functions with such a manual operating device, if required, it is proposed in DE 10 2005 020 775 A1 to construct the manual operating device or respectively the mobile operating device in such a manner that it has a basic operating device and an optional extension module. The basic operating device comprises input and output means, which ensure at least the basic input and output functionality. The extension module is able to be arranged at least partially over the basic device and at least partially covers the latter. The input and output means of the basic device are replaced and/or supplemented by the input and output means of the extension module. More complex input and output functionalities are also able to be presented with the extension module. The input and output possibilities of the extension module therefore exceed as a whole the possibilities of the basic operating device.

From DE 10 2007 050 073 B4 a control device of a plastic-processing machine is known, wherein an operating device is provided with a touch-sensitive screen (touchscreen). The screen is divided, in terms of software, into a first, upper screen region and a second, lower screen region. In the upper screen region the injection moulding machine or parts thereof can be presented. However, operating data such as, for example, temperature values, pressure values etc., can also be presented. Furthermore, soft keys are present there, which can be actuated by means of the arrangement of a touch-sensitive touch surface. Machine input keys or respectively machine operating keys are realized in the second, lower screen region in terms of software or respectively by graphic presentation. The manner of presentation of the machine input keys or respectively of the machine operating keys depends inter alia on the functions which are available on the machine and the mode of operation. Depending on the mode of operation or current operating status, particular operating keys are switched so as to be inactive.

From DE 10 2007 013 735 A1 an injection moulding machine is known, in which an electronic control and several screens in communication with this control are provided with films in OLED technology (OLED: organic light emitting diode), which are detachably secured to the injection moulding machine. The OLED technology makes it possible to construct the screen in its dimensions such that it fits, for example, into the coat pocket of a user. Thereby, an operation of the control can take place so that the user is not committed to a particular location on the injection moulding machine. These OLED screens can therefore also be designated as a mobile operating device. A cable plug connection or a wireless radio connection can be present between these mobile operating devices and the central control of the injection moulding machine. In addition to the control of the injection moulding machine, provision is also made to also operate any handling devices which may be present likewise via the central control of the injection moulding machine and its OLED screens.

From DE 102004051106A1 an injection moulding machine is known, which has at least one operating unit, at least one machine control and at least one subsystem with its own control device. The machine control and the control device of the subsystem generate respectively a screen output and are able to be operated via this. At least one of the operating units is connected or able to be connected both with the machine control and also with the at least one control device of the subsystem for data transmission. The subsystems can be one or more robots. A PC or a laptop can be provided as mobile operating device. According to this prior art, provision is made that the screen outputs of the machine control and of the control devices of the subsystems are able to be shown and operated in different regions of the screen of the at least one operating unit. In order to enable a simultaneous presentation of the several screen outputs on one and the same screen of an operating unit, the screen output of the machine control and of the control devices of the subsystems must be shown in a correspondingly scaled manner. As a result, this leads to an overall presentation which is reduced in size and is therefore poorly discernible.

SUMMARY OF THE INVENTION

Proceeding from the above-mentioned prior art, the problem of the invention lies in indicating a device and a method for operating a machine equipped with a handling device, in particular an injection moulding machine, by which the configuration and running or respectively operating both of the machine and also of the handling device can be carried out more quickly and simply.

According to one aspect of the invention, a device for operating a machine equipped with a handling device, particularly an injection moulding machine, includes a first stationary operating device secured to the machine, and a second mobile operating device, wherein each operating device has input and output means, wherein the stationary operating device is designed both for operating the machine and also for operating the handling device, wherein the mobile operating device is designed both for operating the handling device and also for operating the machine, wherein at least the output means of the stationary and of the mobile operating device are constructed respectively as a screen, wherein the screen of the mobile device is smaller than the screen of the stationary operating device, and wherein predefinable regions of a screen page of the screen of the stationary operating device are able to be shown successively on the screen of the mobile operating device.

According to another aspect of the invention, a method for operating a machine equipped with a handling device, in particular an injection moulding machine, includes a first stationary operating device secured to the machine, and a second mobile operating device, wherein each operating device has input- and output means, wherein the stationary operating device is designed both for operating the machine and also for operating the handling device, wherein the mobile operating device is designed both for operating the handling device and for operating the machine, and wherein at least the output means of the stationary and of the mobile operating device are constructed respectively as a screen, wherein the screen of the mobile operating device is smaller than the screen of the stationary operating device, and wherein predefinable regions of a screen page of the screen of the stationary operating device are shown successively on the screen of the mobile operating device.

Advantageous further developments and embodiments are to be found in the dependent claims.

Through the fact that a first stationary operating device, secured to the machine, and a second mobile operating device are provided, wherein each operating device has input and output means, wherein the stationary operating device is designed both for operating the machine and also for operating the handling device and wherein the mobile operating device is designed both for operating the handling device and also for operating the machine, a complete or respectively fully equipped operating device is respectively available both for the machine and also for the handling device. Whilst the one fully equipped operating device is secured “conventionally” as a stationary operating device as usual on the machine, in particular on the injection moulding machine, a further mobile operating device is available, which is fully equipped for the configuration and operation of the handling device and machine. With the mobile operating device, an operator can move freely around the machine and for example with a view onto the handling device can configure and operate it. Through the full equipping of the mobile operating device, adjustments and operations can also be carried out on the machine itself by this operating device. For example, adjustments concerning the clamping unit of an injection moulding unit can be undertaken and checked by this mobile operating device. By simple “switching over” of the operating device to the adjustment pages for the handling device, for example an adapting of the movements of the handling apparatus to the movements of the movable parts of the clamping unit can be carried out in a simple and quick manner.

At least the output means of the stationary and of the mobile operating device can be constructed respectively as a screen, wherein the screen of the mobile operating device is smaller than the screen of the stationary operating device. Predefinable regions of the screen page of the screen of the stationary operating device can be shown successively on the screen of the mobile operating device. Despite the different size, a full integration is therefore to be present, i.e. all the screen pages which are also able to be shown on the stationary operating device are also to be able to be shown on the smaller screen of the mobile operating device.

The mobile operating device is complete or respectively fully equipped in the sense that on the one hand it corresponds to a fully equipped operating device for the handling device, but on the other hand can also undertake or show all the functions of a fully equipped operating device of the machine. Vice versa, the stationary operating device is complete or respectively fully equipped in the sense that on the one hand it corresponds to a fully equipped operating device for the machine, but on the other hand can also undertake or show all the functions of a fully equipped operating device of the handling device.

Advantageously, all the operating keys which are necessary for the operating both of the machine and also of the handling device are present, or can be produced or respectively presented, both on the stationary operating device and also on the mobile operating device. For this, the input and output means can be designed on the stationary operating device and on the mobile operating device respectively as a touch-sensitive screen (touchscreen).

It is regarded as advantageous in the sense of a full equipping of the two operating devices or respectively a full integration, if both on the stationary and also on the mobile operating device all the screen pages concerning the operation or respectively the control of the machine and all screen pages concerning the operation or respectively the control of the handling device are able to be shown.

In order to simplify the operation of the two operating devices and to avoid operating errors, provision can be made that the form of the operating keys for the machine is the same on the stationary and on the mobile operating device. The presentation of the machine operating keyboard is therefore advantageously identical on the two operating devices. This increases the safety during configuring and operating the machine, because the risk of operating errors is reduced. Identical functions of the machine are represented or able to be represented by identical operating keys on the stationary and mobile operating device. For example, machine operating keys for the functions “injection unit forward” or respectively “injection unit reverse” are indicated in an identical manner on the two operating devices, when the screen page appertaining respectively hereto has been selected on the respective operating device.

The above applies correspondingly also for the form of the operating keys for the handling device on the stationary and on the mobile operating device. The operating keys for the handling device, for example the start-up and shut-down of a gripper, are indicated in an identical manner on the two operating devices, when the screen page appertaining hereto has been selected on the respective operating device.

To improve the ease of use, provision can be made that the stationary operating device and/or the mobile operating device have switchover elements, by the actuation of which the presentation on the screen can be changed, wherein a changeover can be carried out between a presentation of the display—and operating field of the machine and a presentation of the display—and operating field of the handling device.

In a particularly advantageous embodiment, provision can be made that the stationary operating device and the mobile operating device are constructed respectively as a touch-sensitive screen (touchscreen), wherein the screen of the mobile operating device is smaller than the screen of the stationary operating device. This facilitates the handling of the mobile operating device. On the other hand, however, the mobile operating device is to have the same full equipping as the larger stationary operating device. Therefore, despite the different size, a full integration is to be present, i.e. all screen pages which are also able to be shown on the stationary operating device are also to be able to be shown on the smaller screen of the mobile operating device. For this purpose, provision is made that predefinable regions of a screen page of the screen of the stationary operating device are able to be shown successively on the screen of the mobile operating device. For example, provision can be made that the screen is divided on the stationary operating device in terms of software, in particular into an upper and a lower part. The two parts of the screen of the stationary operating device are then able to be shown individually respectively separately on the screen of the mobile operating device. Whether all elements of the presentation of the larger touchscreen are taken over identically or whether there are slight adaptations depends on the respective circumstances. A changeover can then be made back and forth between the presentation of the one part of the screen of the stationary operating device and the presentation of the other part of the screen. If necessary, also only particular regions of a screen page of the stationary operating device can be shown on the mobile operating device. If such a region is smaller than the screen area available on the touchscreen of the mobile operating device, other adjusting or operating elements can be displayed in the region which is still free, according to requirements. In any case, in this way all screen pages of the stationary operating device can be shown on the smaller mobile operating device or respectively on the smaller touchscreen of the mobile operating device.

In order to also enable extensive or respectively more complex configurations or a complete configuration or respectively programming of the machine via the mobile operating device, provision can be made that operating keys of the machine and input fields for the inputting of parameters for operating the machine are present or are able to be shown on the mobile operating device. The above also applies correspondingly for the handling device. Consequently, operating keys of the handling device and input fields for the inputting of parameters for the operation of the handling device should be present or able to be shown on the stationary operating device, so that also extensive or respectively more complex configurations or a complete configuration of the handling device becomes possible.

In the sense of the present invention, the configuration is also to include the programming of a cycle of the machine. In particular, the configuration is also to include the programming of a cycle of an injection moulding cycle. This programming can take place by means of graphic symbols for particular functions. These symbols can also be designated as icons. Advantageously, the same icons are provided for the programming of an injection moulding cycle on the mobile operating device as on the stationary operating device. As a whole, the operating philosophy or respectively the programming philosophy of the stationary and mobile operating device is to be the same.

As a whole, provision is therefore made according to the invention that the injection moulding machine can also be completely configured or respectively programmed and operated from the mobile operating device.

The presentation of the screen pages on the stationary operating device and the presentation of the screen pages on the mobile operating device are preferably independent of one another. On the other hand, provision is preferably made that the display of data or of graphic information always takes place, however, from the control component which has received the data or signals. If, therefore, data or signals are concerned, which relate to the handling device, then these data or signals are conveyed from the control component of the handling device to the two operating devices. If data or signals are concerned, which relate to the actual injection moulding machine, then these data or signals are conveyed from the control component of the injection moulding machine to the two operating devices. The production of the layout of the screen pages on the one hand and the displaying of contents in these layouts (data, graphic information of linear robot and injection moulding machine) therefore takes place independently or separately from one another. The two above-mentioned control components can be regarded in a combined manner as a central control or central control device of an entire installation. Each of these control components can have one or more CPUs. In addition to an injection moulding machine and a handling device, the entire installation can also have further components, for example a hot runner system or a temperature control unit. Further control units can be associated with the further components within the central control. The further control components can, however, also be integrated into the data network of the entire installation detached from the central control device.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

FIG. 1shows diagrammatically an injection moulding machine with a machine bed1, on which an injection unit2and a clamping unit3are arranged. The clamping unit3comprises a stationary platen3aand a movable platen3bwhich is able to be moved with respect thereto. The two platens carry mould halves4aand4b, which in the closed state form cavities. By means of the injection unit2, a plastic melt can be produced and injected into the cavities, where the plastic melt can harden to form plastic moulded parts. After opening of the mould halves4aand4b, these moulded parts can be removed by means of a linear robot5, known per se. Instead of the linear robot5, other types of handling devices can also be provided. For example, a six-axis industrial robot could be installed on the floor adjacent to the injection moulding machine. In the region between the stationary platen3aand the front end of the injection unit2, a stationary operating device6is provided for configuration and operation of the injection moulding machine. This operating device6is fully equipped for configuring or respectively programming the injection moulding machine on the one hand and for configuring or respectively programming the linear robot5on the other hand. Of course, all other adjustment operations necessary for the operation of the injection moulding machine and of the linear robot can be carried out via this operating device6. Preferably, the operating device has a touch-sensitive screen, also designated as a touchscreen. In a particularly preferred embodiment, the entire surface of the operating device6is embodied as a touchscreen and all input—and operating fields are shown in terms of software on the operating device6, as is known from DE102007050073B4 of the applicant, mentioned in the introduction. Alternatively or additionally, however, further switches and keys and a screen for the input and output of data can also be provided. The operating unit6is connected via a bidirectional data connection32with the control component30bof the injection moulding machine (seeFIG. 2). The bidirectional data connection can be constructed as a data line32, i.e. the data connection takes place by means of cables. The data transmission can, however, also take place wirelessly or respectively by radio, i.e. the bidirectional data connection32is constructed as a radio connection.

InFIG. 1, furthermore, on the right, adjacent to the injection moulding machine, an operator is illustrated, who is holding a mobile operating device7in one hand. The external dimensions of the mobile operating device7are considerably smaller than the external dimensions of the stationary operating device6. Preferably, the mobile operating device7also has a touch-sensitive screen (touchscreen). In a particularly preferred embodiment, the entire surface of the operating device7is embodied as a touchscreen and all the input—and operating fields are shown in terms of software on the operating device6, as is known from DE102007050073B4 of the applicant, mentioned in the introduction. However, alternatively or additionally, further switches and keys and a screen can also be provided for the input and output of data.

According to the invention, provision is now made that not only is the stationary operating device6designed both for operating the injection moulding machine and also for operating the handling device or respectively linear robot5, but that also the mobile operating device7is designed both for operating the linear robot5and also for operating the injection moulding machine. Both on the stationary operating device6and also on the mobile operating device7, all operating keys are present, or can be produced there, which are necessary for the operating both of the injection moulding machine and also of the linear robot5. Both on the stationary and also on the mobile operating device, all screen pages concerning the operation or respectively control of the injection moulding machine, including the configuration or respectively programming of the injection moulding machine, and all screen pages concerning the operation or respectively the control of the linear robot5, including the configuration or respectively programming of the linear robot, are able to be shown.

The central idea of the present invention is to be explained in further detail with the aid ofFIGS. 2 and 3.

FIG. 2shows the touch-sensitive screen or respectively touchscreen8of the stationary operating device6. The touchscreen8can be divided conceptually into several regions8A-8E, the meaning of which is to be explained further below. According to the design of the operating device, the touchscreen8can form almost the entire surface of the operating device6.FIG. 3shows the touch-sensitive screen or respectively touchscreen9of the mobile operating device7. According to the design of the operating device7, the touchscreen9can also form almost the entire surface of the operating device7. The touchscreen9is illustrated inFIG. 3in two different operating states or respectively settings. The touchscreen9displays, in one setting, the screen page10a, and in another setting, the screen page10b. In the presentation of the screen page10b, the touchscreen9can be divided conceptually into several regions9A and9B, the meaning of which is to be explained further below.

The central control30of the entire system, i.e. in the present example, the central control30of the injection moulding machine equipped with a handling device (e.g. a linear robot), comprises two control components with in each case their own CPU unit, namely a first control component30a, which forms the control device for the linear robot5, and a second control component30b, which forms the control device for the actual injection moulding machine. Each CPU unit can have one or more CPUs. The first control component30afor the control of the linear robot5is connected via data lines38with the actuators and sensors of the linear robot5. The second control component30bfor the control of the actual injection moulding machine is connected via data lines36with the actuators and sensors of the injection moulding machine. A data exchange (indicated by double arrow P) can take place between the two control components30aand30b. This means that data can be exchanged between the CPU unit of the control device for the linear robot and the CPU unit of the control device for the actual injection moulding machine. The control component30bfor the actual injection moulding machine is connected via a first bidirectional data line32with the stationary operating device6or respectively with the stationary touchscreen8. Video signals are transferred from the control component30bto the screen8via this bidirectional data line32. The screen pages on the screen8are produced via this data line32and filled with content. This means that both the layout of the screen pages is produced, and also display fields are filled with data or graphic representations with information, for example with a temperature reading (e.g. 200° C.) or a curve progression for a particular parameter. Solely the control component30bis responsible for the production of the layout. According to the operating mode, the data which are to be displayed come from the control component30aor from the control component30b, as is explained further below. Inputs carried out on the touchscreen8or inputs carried out via a keyboard on the operating device6are conveyed to the central control30via the same data line32. According to the operating mode, these inputs are transferred to the control component30aor to the control component30b. If interfaces for data transmission are provided on the operating device6, for example a USB interface, data can also be conveyed from this interface to the central control30.

In an analogous manner, the control component30afor the linear robot5is connected with the mobile operating device7via a second bidirectional data line34. Video signals are transferred from the control component30ato the screen9via this bidirectional data line34. The screen pages on the screen9are produced via this data line.34and filled with content. This means that both the layout of the screen pages is produced, and also display fields are filled with data or graphic presentations are filled with information, for example with an indication of position for an element of the linear robot5(e.g. 50 cm). Solely the control component30aof the handling device or respectively the CPU unit appertaining hereto is responsible for the production of the layout of the screen pages. The data or graphic information which are to be displayed come, according to the operating mode, from the control part30aor from the control part30b, as is additionally explained further below. Via the same data line34, inputs carried out on the touchscreen9or inputs carried out via a keyboard on the mobile operating device7are conveyed to the central control30. If interfaces for data transmission are provided on the mobile operating device7, for example a USB interface, data can also be conveyed from this interface to the central control30.

As a result, therefore, an entirely specific operating device is associated with each control component with regard to the presentation of the screen pages. The layout of the screen pages of a particular operating device is therefore produced exclusively from the control component associated with this operating device. The presentation of the screen pages on the stationary operating device and the presentation of the screen pages on the mobile operating device are therefore independent of one another. The display of data or of graphic information takes place, however, always from the control component which has received the data or signals. If data or signals are concerned which relate to the linear robot5, these data or signals are conveyed from the component30ato the two operating devices. If data or signals are concerned which relate to the actual injection moulding machine, these data or signals are conveyed from the control component30bto the two operating devices. The production of the layout of the screen pages on the one hand and the displaying of contents in these layouts (data, graphic information of linear robot and injection moulding machine) therefore takes place independently or separately from one another.

The stationary operating device6is therefore designed both for operating the injection moulding machine and also for operating the handling device, i.e. the linear robot5. Vice versa, the mobile operating device7is also designed both for operating the handling device and also for operating the machine. This is to be explained in following examples. It is to be assumed that the linear robot5can be operated from both operating devices6and7. For this, in the operating devices6and7respectively the “handling device” operating mode is to be selected. The layout of the screen pages on the stationary operating device6is produced solely from the control component30bof the actual injection moulding machine. However, screen pages for the adjustment and/or operation of the linear robot5are produced and displayed. The data themselves which are to be displayed come from the control component30aof the linear robot. These data are produced from the control component30aand are transferred via the control component30bto the stationary operating device6and are displayed there. The layout of the screen pages on the mobile operating device7is produced solely from the control component30aof the linear robot, wherein screen pages for the adjustment and/or operation of the linear robot are produced and displayed. The data which are to be displayed are produced from the control component30aand transferred from there directly to the mobile operating device7and are displayed there. Inputs at the stationary operating device6are transferred “through”, via the data line32and the control component30b, to the control component30afor the linear robot. Inputs at the mobile operating device7are transferred via the data line34directly to the control component30afor the linear robot. In a subsequent step, the concern is to be that settings are to be carried out on the actual injection moulding machine, wherein the injection moulding machine is to be operated from both operating devices6and7. For this, the “injection moulding machine” operating mode is to be selected respectively in the operating devices6and7. The layout of the screen pages on the stationary operating device6is still produced solely from the control component30bof the actual injection moulding machine. In contrast to previously, screen pages are now displayed for the adjustment and/or operation of the injection moulding machine. The data to be displayed on the operating device6, in contrast to previously, come from the control component30bof the actual injection moulding machine. The layout of the screen pages on the mobile operating device7is produced solely from the control component30aof the linear robot, wherein, however, screen pages are displayed for the adjustment and/or operation of the injection moulding machine. The data which are to be displayed themselves are produced from the control component30bof the injection moulding machine, transferred to the control component30aof the linear robot and from there via the data line34to the screen9of the mobile operating device7. Inputs at the stationary operating device6are transferred via the data line32to the control component30bfor the injection moulding machine. Inputs at the mobile operating device7are transferred via the data line34to the control component30afor the linear robot and from there on to the control component30bfor the injection moulding machine.

As can be readily seen fromFIGS. 1-3, the external dimensions of the mobile operating device7and of its touchscreen9are distinctly smaller than the external dimensions of the stationary operating device6and of its touchscreen8. The distinctly smaller size of the mobile operating device facilitates its handling by an operator. It is advantageous for practice if a comparatively small and manageable operating device is available for an operator, which the operator can carry around with him/her. Typically, the mobile operating device7is only approximately half as large as the stationary operating device6or even smaller. Accordingly, the touchscreen9is typically only approximately half as large as the touchscreen8or even smaller. In the embodiment which is shown here, the size of the touchscreen9inFIG. 3corresponds substantially to the region8A of the touchscreen8ofFIG. 2, situated above the line L. Basically, the smaller touchscreen9can also form a smaller or larger region of the touchscreen8.

The screen page10acorresponds in its presentation and with respect to the available functionalities to the region8A of the touchscreen8situated above the line L. Therefore, the same inputs can be carried out on the touchscreen10aas on the region8A of the touchscreen8. For example, a window12with input elements or input fields12acan be presented in terms of software identically on the touchscreen8and on the touchscreen10a. The form of the input fields12ais therefore the same on both screens8and10a. For example, these could be input fields for the input of temperature- or pressure values. The result of the input is independent of whether the input is made on the touch screen8or on the touchscreen10a. In both cases, the input is transferred to the control30of the injection moulding machine and brings about the desired adjustment on the injection moulding machine. If, on the basis of this input, a change is produced with regard to the course of a particular parameter shown in the graph13, this change is displayed identically on the touchscreen8and on the touchscreen9—in its operating position according to10a.

The screen page10bcorresponds in a region9B, in its presentation and with respect to the available functionalities, to the regions8C,8D and8E of the screen page ofFIG. 2. These regions8C,8D and8E do not, however, fill the entire surface of the touchscreen9, so that a region9A remains, which is available for further displays and/or inputs. The regions8C,8D and BE are presented identically on the touchscreen8and on the touchscreen10a. Therefore, all machine operating keys from the region8D are also displayed identically on the touchscreen8and on the touchscreen9—in its operating position according to10b. The form of the machine operating keys and the form of the other keys and/or displays is therefore the same on both screens8and10a. By way of example, in this respect the machine keys are named for the functions “injection unit forward” or respectively “injection unit reverse”, which are marked inFIGS. 2 and 3with the reference numbers14aand14b. The above-mentioned movements of the injection unit can therefore be carried out with the same machine operating keys and with the same effect (namely the desired movement) both on the stationary operating device6and also on the mobile operating device7.

Preferably, not only is an identical form or respectively identical design of the operating keys and other keys and/or displays provided, but preferably the entire operating—and display philosophy is to be the same on both operating devices.

Owing to the smaller dimensions of the mobile operating device7or respectively its touchscreen9, provision is made according to the invention that predefinable regions of the touchscreen8of the stationary operating device6can be shown successively on the touchscreen9of the mobile operating device6or respectively on its touchscreen9. A screen page of the large touchscreen8is divided as it were in terms of software into several smaller regions, which fit onto the smaller touchscreen and can be displayed there as separate screen pages. The production of the screen pages on the large touchscreen8and the production of the screen pages on the small touchscreen9takes place, however, independently of one another, as described above. In other words, this means that it only has the appearance is if individual regions of a screen page of the large touchscreen8were transferred from this successively to the mobile operating device7and shown there successively on the small touchscreen9. However, this is not the case. Rather, the situation is that the regions to be displayed on the small touchscreen9are produced in the control component30aof the linear robot itself and are displayed on the touchscreen9. Provision made furthermore here that a shift key15is provided, by which a switchover can be carried out directly to the presentation according to the screen page10b. Therefore, a changeover can be made on the mobile operating device6directly from the display of the region8A to the machine operating keyboard according to the region8D. A “return” key16can be provided as shift key on the screen page10b, in order to arrive from the display according to10bwith the machine operating keys back to the display according to10a. Instead of the use of shift keys15or respectively16, the “switchover” between the screen pages10aand10band vice versa can also take place by gesture, for example by sliding or swiping of the screen pages toward the left or right or upwards or downwards. In other words, the individual regions of the large touchscreen could also be shown successively by scrolling (in vertical or horizontal direction). Which regions of the large touchscreen8are or can be distributed onto which screen pages10a,10betc. of the smaller touchscreen7and displayed successively depends ultimately on how the displaying of the screen pages is configured in terms of software. A variety of setting possibilities are conceivable here. As a result, the displayed regions can be presented on both touchscreens8and9therefore substantially in equal size.

Both on the large touchscreen8and also on the small touchscreen switchover elements17a,17bare presented and able to be selected, by means of which a switchover can be carried out directly back and forth between the “injection moulding machine” operating mode and the “handling device” operating mode. If, for example, the mobile operating device is being used by the operator with regard to the robot5in the “handling device” operating mode, in order to carry out adjustments on the robot, a switchover can be carried out directly to the “injection moulding machine” operating mode, if required, by means of the switchover element17b, in order, for example, to carry out adjustments on the clamping unit3. Following this, the operator can change back again and directly into the “handling device” operating mode. In each operating mode, respectively all available adjustment pages and operating keys can be selected. The production of these adjustment pages and operating keys (layout of the screen page) takes place for the stationary operating device6by means of the control component30bassociated with this operating device6. On the other hand, the production of the adjustment pages and operating keys for the mobile operating device (i.e. layout of the screen pages) takes place by means of the control component30aassociated with this mobile operating device. In particular, all adjustment pages of the injection moulding machine and all machine operating keys of the injection moulding machine are available on the mobile operating device, or respectively can be produced and displayed there from the control component30a, when the mobile operating device is in the “injection moulding machine” mode. Vice versa, all the adjustment pages of the linear robot and operating keys of the linear robot are available on the stationary operating device or respectively can be produced and displayed there from the control component30b, when the stationary operating device is in the “handling device” operating mode. As a whole, therefore, a full integration of injection moulding machine and handling device is the result.

As the presentation of the screen pages on the stationary operating device and the presentation of the screen pages on the mobile operating device takes place independently of one another, the screen pages or respectively the layout could be very different on these operating devices, even if they are both in the same operating mode. To simplify the operating, the screen pages should, however, be as far as possible identical or very similar in their layout. For example, the regions from the large touchscreen which are to be displayed on the small touchscreen9should be largely identical in their presentation (layout, size) to the same regions, as are displayed on the large touchscreen. However, it would be conceivable for example to present the screen pages for the adjustment and/or operation of the linear robot on the mobile operating device7in a first colour (e.g. blue) and on the stationary operating device in a second colour (e.g. green).
