Description

Technical FieldThe present invention relates to an operator assistance system for a user of a container treatment system, in particular a bottle filling system. Container treatment systems of this type, with, for example, filling devices or blowing devices for plastic containers, inspection devices, transport devices, packaging devices, marking devices or labeling devices, are known from the prior art.Prior ArtDuring the operation of a container treatment plant, operating processes, changeover work, supply steps, steps of error correction (trouble shooting) or the like are necessary in the course of the application. Container treatment installations are usually very large installations which are not fully reviewed and understood by a user immediately at the beginning of an operation. Due to the changing structure and the complexity of the installations, the operating sequence of the installation is usually unknown to the user and is difficult to understand. The achievement of the tasks by a user is strongly dependent on its performance and know-how. As a consequence, the efficiency of the container treatment facility is also dependent on the performance of the individual user operating in the facility.EP 2901225 discloses an operating system for a system, in particular for a beverage processing machine. The operating system comprises a mobile operating device for the system, a signal transmitter for reporting alarm and / or warning signals, and spectacles, which comprise a display system, which is in particular designed as a head-mounted display or virtual retinal display or projector, and wherein the operating device and / or the signal transmitter and / or the safety spectacles each comprise a data transmitter for exchanging machine information and / or alarm and / or warning signals. A user of the operating system is provided with virtual operating devices of the installation displayed on the display system and can change parameters of the installation particularly easily by means of gestures or operating devices. The operating system can indicate supply residues, incorrect behavior of the installation or the like via the display system and inform the user of this.WO 2016207948 provides a control system for a user on the basis of which the user can be controlled from a currently located position to a process device in a plant on which a working step is to be carried out. The user is displayed by a display device its current position and a path that the user can take in a work area. The user is thus guided as quickly as possible to a process device on which a working step is to be carried out. This increases the efficiency of the plant by coordinating the movement of a user in a plant.However, the achievement of the tasks by the user continues to be strongly dependent on the level and receptivity thereof. A user who has never or rarely operated a device in the installation to which he is guided does not know how to operate it. The device parameters are displayed to him, but the user needs to prepare or instruct it to operate the device for proper operation. This can lead to time losses until the user has understood which working step is to be carried out and how an optimum setting of the installation is configured. On the other hand, incorrect operation can lead to operating pauses or to the operating process of the system being shut down. This causes delays in the process sequences of the container treatment plant and thus leads to a reduction in the productivity of the container treatment plant.The object is to provide a method for performing a processThe present invention is therefore based on the object of providing an operator assistance system which makes it possible to simplify the operation of devices in a container treatment installation by assisting the user. In addition, the operating reliability for such installations is to be increased. This object is achieved according to the invention by the subject matter of claim 1. A method for solving the above problems is solved by the display method according to claim 11. Advantageous embodiments and developments are the subject matter of the dependent claims.SolutionAn operator assistance system according to the invention for a user of a container treatment system, in particular a bottle filling system, comprises a position detection device which detects a position and orientation of the user in the container treatment system, wherein the position detection device identifies a treatment device in the container treatment system which is operated by the user on the basis of the position and orientation of the user, an operation detection device which detects the operating state of the identified treatment device, and a mobile operator assistance device which assists the user on the basis of the operating state of the identified treatment device during the operation of the treatment device by means of operator recommendations.This results in the advantage that the operator assistance system according to the invention assists the user with active operator instructions to operate the container treatment system appropriately and in a targeted manner. The operator is not only guided to a problem location, but is actively supported in the implementation of the problem solution. This results in a more rapid and simpler operation of the system, an appropriate reaction to errors, targeted changeover and timely supply of the devices within the container treatment system, regardless of the degree of design and level of knowledge of the user. This leads to an increase in the efficiency and productivity of the container treatment plant. The mobility of the operator assistance device ensures simple handling of the system and the possibility of retrofitting existing container treatment installations.Advantageous further developments of the invention are the subject matter of the dependent claims.It can be advantageous if the position detection device, the operation detection device and the mobile operation assistance device are combined in one device, preferably in spectacles which superimposes information into the field of vision of the user, more preferably augmented reality spectacles. The inclusion of features in an apparatus promotes system compactness and thus comfort for the user, who can thus move more quickly in the facility. Such a combination in an apparatus also simplifies retrofitting an existing container treatment system, since only the spectacles and their connection to a control station are required. The use of eyeglasses or augmented reality eyeglasses enables the simultaneous view of the installation and the settings and parameters of a device to be operated. The use of augmented reality glasses also wakes up the neugia and increases the user's marketing of reliable work. At the same time, the mobile operator assistance device in the form of spectacles can avoid the space requirement for extensive displays within the container treatment installation.It may prove to be useful if the operator support system further comprises at least one data transmitter for exchanging status information between the position detection device, the operator detection device, the mobile operator support device and a control station of the container treatment installation, wherein the control station is preferably an external server or a cloud. Thus, wireless exchange between the devices may take place and state information may be exchanged in real time. At the same time, the external processing of data makes it possible to avoid the space requirement for extensive server systems within the container treatment system. Such a configuration of the operator assistance system also simplifies retrofitting an existing container treatment system, since only the spectacles and their connection to the control station are required.It can be helpful if the operator assistance system further comprises a state simulation device which simulates a digital image of the operating state of each treatment device of the container treatment system, preferably simultaneously with the operation, by taking into account the environmental boundary conditions, simulates operating scenarios and transmits operator recommendations to the mobile operator assistance device by means of a data transmitter on the basis of the results thereof. This has the advantage that with a digital twin of the installation, virtual operating scenarios can be simulated in such a way that parameter recommendations can be calculated in real time, which cause improved operation of the installation. The state simulation device simulates best-case scenarios and runs through optimization loops and thus has low-complexity access to operating states of the installation, on the basis of which decisions about the operating state can be made, for example by a AI-controlled strategy.It can prove to be advantageous if the operating recommendations are displayed by the mobile operating assistance device and are at least one, two or more of the following: parameter setting specifications for control variables of the treatment device, virtual display of an operation of the treatment device, preferably an operation by means of a tool, measures for eliminating errors in the treatment device or optimization suggestions for arranging the treatment device in the container treatment plant. It can thus be achieved that the devices in the installation are suitably set, repairs to the installation can be carried out quickly, faults can be corrected quickly and the installation is in the arrangement suitable for the application. This increases in total the availability and efficiency of the plant.It can be useful if the operation assistance system further comprises a display device which displays a direction of a shortest path to a further treatment device, preferably projected by an arrow on the ground, more preferably from the mobile operation assistance device onto the ground, wherein the further treatment device is a treatment device on which an operation recommendations are to be carried out. If a parameter change, error correction or a supply step is to be carried out on a second treatment device, this ensures marked travel paths for users and thus a rapid reaching and timely implementation of the operating steps of the second treatment device.It can be practical if the mobile operator assistance device comprises a hearing / speaking unit which comprises a speech recognition and is in particular connected to the data transmitter of the operator assistance device for the exchange of speech information. This enables rapid information exchange and temporal optimization of the operation of the installation, since a selection of at least one operation recommendation is recognized and is returned to the container treatment installation. It can also be practical if the mobile operator assistance device comprises an hearing protector for suppressing disruptive ambient noises, which in particular operates with active noise suppression. Such a device promotes the concentration of the user to carry out working steps on the installation. It can also be practical if the mobile operator assistance device comprises a camera for detecting objects in the field of view of the user and for recording states occurring in the field of view of the user. Thus, a work area of the user can be recorded, for example, for learning and training purposes, and an image or expert can track the user's view in order to detect malfunctions and to be able to provide further operating instructions. It can also be practical if the mobile operator assistance device comprises a second camera, which is designed to capture at least one eye of the user in order to identify the user and / or is designed to recognize a viewing direction of the user. Thus, a profile can be assigned to the user depending on the level of knowledge and the level of knowledge of the user can be incorporated into the operator assistance. By means of such a profile, an authorization level of the user can be queried, which influences the user interface or prevents the user from specific work tasks with a higher safety level. In addition, control and selection of recommendations about the gaze of the user can be carried out via such a second camera. This enables rapid information exchange and a temporal optimization of the operation of the installation, since a selection of at least one operation recommendation is recognized and is returned to the container treatment installation. It may also be practical if the mobile operation support device comprises a gesture recognition unit for recognizing gestures of the user. This enables a rapid selection of the operating recommendations and a temporal optimization of the operation of the installation, since a selection of at least one operating recommendation is recognized and is returned to the container treatment installation. It may also be practical if the mobile operation assistance device displays two different images to the user in order to display an actual state and a recommended state of the treatment device. Thus, the user views at a glance a large number of information necessary for the operation in order to carry out a working step quickly and in a targeted manner.It may prove to be useful if the position detection device records and stores the paths of the user and the state information and environmental constraints of the operation, and the operation detection device records and stores the environmental constraints and the operating state of the treatment device arranged on the path of the user. This serves for documentation of the execution of working steps and support of the data analysis for feeding the simulations and preparing operating processes of the plant. Conclusions can also be drawn about the efficiency of a user and of the treatment devices.The invention furthermore comprises a container treatment system, in particular a bottle filling system, which comprises at least one treatment device which treats a container (B) and an operator assistance system according to one of the preceding aspects.An operating method according to the invention for supporting a user of a container treatment system, in particular a bottle filling system, comprises detecting a position and orientation of the user in the container treatment system, wherein a treatment device which is operated by the user is detected in the container treatment system on the basis of the position and orientation of the user, detecting an operating state of the detected treatment device and supporting the user during the operation of the detected treatment device by means of operating recommendations, on the basis of the operating state of the detected treatment device.Further preferred developments of the invention result from combinations of the features disclosed in the description, the claims and the figures.Brief Description of the FiguresThe following are shown: FIG. 1 shows a perspective view of a user with the operator assistance system in front of a treatment device of a container treatment system. FIG. 2 shows a mobile operator assistance device of the operator assistance system in the form of augmented reality glasses FIG. 3 shows a container treatment system with a plurality of treatment devices.DETAILED DESCRIPTION OF THE INVENTIONFIG. 1 shows a perspective view of a user A with the operator assistance system 2 in front of a treatment device 4 of a container treatment system 1. FIG. 1 is a two-dimensional plan view of the container treatment system 1. the container treatment system 1 is a processing line of devices for treating containers B and in particular beverage containers B with at least one treatment device 4. the processing line can be of modular construction and can be composed of transport devices, blow moulding devices, filling devices, inspection devices, packaging devices, marking devices, labeling devices and the like which carry out processing steps on the containers B. Mobile supply devices can also be mounted on the processing line. By means of conversion work, the processing line can be converted as required, so that the processing line can process containers B made of different materials in different sizes and numbers.The treatment device 4 comprises a display device 8 on which an operating status of the treatment device 4 can be displayed. The display device 8 displays the actual state of the treatment device 4 or indicates a supply state. Possible supply supply supply supplies or malfunctions are also displayed on the display device 8. The display device 8 may also be used as a control panel to accept input from a user A. In other words, the display device 8 is a touch-sensitive display device, and a displayed view can also be moved, rotated, and / or zoomed by touch.The user A is equipped with an operation support system 2. The operation support system 2 includes a position detection device 3, an operation detection device 5, and a mobile operation support device 6. This device is preferably a pair of eyeglasses 7 which superimposes information into the field of vision of the user. More preferably, the eyeglasses are augmented reality eyeglasses 7.The position detection device 3 detects the actual position and orientation of the user A and passes them on to the operator assistance system 2, so that a treatment device 4 can be detected in the container treatment system 2, in front of which the user A is standing or which the user A operates. The localization can be carried out by means of GPS or an indoor positioning technology such as, for example. The radio frequency identification (RFID), Bluetooth or W-Lan can be carried out in an ultra-wideband (UWB), radio frequency identification (RFID). The treatment device 4 operated by the user A can also be captured by detecting QR codes on the treatment device 4, which are recorded by means of the camera 5 in the operation support system 2. It is thus possible that a detection of the treatment device 4 can take place without locating the user. Nevertheless, the position of the user A can be deduced via a plant plan of the container treatment plant 1.The operation detection device 5 determines the current operating state of the container treatment system 4 in front of which the user with the operator assistance system 2 is located. This is done in the case of less complex container treatment installations 4 (only on / off) by means of camera 5. For the majority of the container treatment installations 4, the operation detection device 5 acquires operating information from a control station 9 of the container treatment installation 1 (not illustrated). The control station 9 is preferably an external device in the form of a server or a cloud.The control station 9 is configured to simulate a digital image of the operating state of each treatment device 4 of the container treatment installation 1, preferably simultaneously with the operation of the container treatment installation, by taking into account the environmental boundary conditions. Furthermore, operating scenarios are simulated on the control station 9 and their results are analyzed. From the simulation results, parameter changes are generated, the potential having to optimize the operation of the treatment devices 4 in the container treatment plant 1. These include, for example, rinsing temperatures for the reliable but rapid rinsing of containers B, transfer speeds of the containers B to transfer devices for avoiding jams, holding forces of the containers B and the like. From the simulation, therefore, operating recommendations are generated based on the operating state of the treatment device 4 detected by the operation detection device 5 in order to optimize the operation of the treatment device 4.The mobile operation assistance device 6 is configured to transfer the operation recommendations of the detected treatment device 4 to the user A and thus to assist the user A in the operation of the treatment device 4 by means of operation recommendations. The operation detection device 5 is connected to the mobile operation support device 6 and additionally displays the operating state of the detected container treatment system 4 on the mobile operation support device 6.FIG. 2 shows a perspective illustration of the operator assistance device 6 in the form of spectacles 7. the position detection device 3 and the operation detection device 5, in the form of a camera 5, can be integrated in the spectacles 7. As shown in FIG. 2, the eyeglasses 7 include an eyeglass frame 7a into which the eyeglasses 7b are fitted. Furthermore, the eyeglasses 7 have two eyeglasses 7c worn over the ears of the user A. In front of each eyeglass lens 7b of the eyeglasses 7, an eyeglass display device 7d is disposed. These are each designed as an optical glass or head-mounted display 7 d 1, 7 d 2. The head-mounted displays 7 d 1, 7 d 2 have optics with which different images of LCD displays are shown to the user A for each eye. In this case, the head-mounted displays 7 d 1, 7 d 2 are semi-transmissive (semi-transparent), such that the user A can simultaneously see the environment in front of the safety glasses 7. With the display device 7 d, different images can be displayed to the user A for each eye, so that he can also view three-dimensional information. Consequently, the user A sees the environment through the eyeglasses 7, on the one hand, and virtual information superimposed therewith, on the other hand. For example, similar to a legend in a drawing, the user A can be presented with the set parameters and / or the tool type suitable for this purpose in relation to a treatment device located in the field of view.The operation support device 6 includes a data transmitter 10 configured to exchange state information among the position detection device 3, the operation detection device 5, and the mobile operation support device 6. The data transmitter 50 is designed as a wireless radio interface. The radio interface can be a WLAN or Bluetooth interface. The eyeglasses 7 are connected to the container treatment system 4 of FIG. 1 by the data transmitter 10. The spectacles 7 can likewise be connected to the control station 9. By this connection, data can be exchanged between the units. The eyeglasses 7 also have the first camera 5 that faces forward and captures the field of view of the user A. In this case, the first camera 5 generates image data from the environment directly in front of the user A, wherein these can be passed on to colleagues via the data transmitter 10, so that these can assist the user A in servicing. Objects or also QR codes can likewise be automatically recognized from the image data in the field of view of the user A. Furthermore, a gesture recognition unit 12 detects the hands of the user A to pick up his gestures as sequences. The sequences obtained in this way can be transmitted via the data transmitter 10 to the control station 9 in order to analyze the gestures.Furthermore, the spectacles 7 have a hearing / speaking unit 11, 13. This device has a headset with integrated hearing protection. Here, the earphones 13 are formed as plugs (in-ear earphones) for each ear so as to seal them from the auditory canal. This suppresses disturbing ambient noises and cannot penetrate into the auditory canal. At the same time, a microphone 11 detects the disturbing ambient noises from the outside and additionally outputs a compensation signal through the earphones 13, so that the remaining ambient noises are further reduced. In addition, useful signals, such as human voices, are detected by the microphone 11 and filtered out by a filter unit (not shown here) and input to the user A via the earphones 13 in a manner isolated from the ambient noises. This allows the user A to communicate with colleagues on site. Furthermore, the hearing / speaking unit 11, 13 shown can be used as a telephone device in conjunction with a cell phone or further units of the operator assistance system 2. For example, to talk to colleagues who are not on site. The hearing / speaking unit 11, 13 can be connected to external units via a data transmitter 10, in particular in order to transmit voice data.Moreover, the eyeglasses 7 have a second camera 15 directed to an eye of the user A. Image data of the second camera 15 is forwarded to the control station 9 by means of the data transmitter 10. There they serve for analyzing the viewing direction and for identifying the user A via biometric recognition features.In addition, the eyeglasses 7 can have the position detection device 3 in the form of a position sensor 3, with which the position and orientation of the eyeglasses 7 can be determined. The position sensor 3 has a plurality of acceleration sensors and position sensors. As a result, the orientation and position of the head of the user A relative to the container treatment system 4 can be determined. The spectacles 7 have a battery for supplying energy (not shown here) and can also comprise a separate microprocessor as control unit.Using the operator assistance device 6 or the spectacles 7, operator recommendations are provided to the user A by the control station 9. The operating recommendations are provided to the applicant A by means of voice transmission via the hearing / speaking unit 11, 13 or in image format via the display device 7 d. The user A can accept or reject the operating recommendations by means of voice control, gesture control or gaze control. The operation recommendations are provided to the user A by the mobile operation support device 6. The operating recommendations are parameter setting specifications for manipulated variables of the treatment apparatus 4, virtual displays of an operation of the treatment apparatus 4, for example an operation by means of tools, measures for solving errors in the treatment apparatus 4 or optimization suggestions for arranging the treatment apparatus 4 in the container treatment plant 1.FIG. 3 shows a container treatment system 1 with a plurality of treatment devices 4. each treatment device 4 comprises a display device 8 and a data transmitter 10. The control station 9 with the state simulation device 9 aalso comprises a data transmitter 10.Operating situations can occur in which an operating recommendation is to be carried out on at least two container treatment systems 4. Thus, a user A must be guided from a first treatment device 4 on which a first recommended step has been carried out to a further treatment device 4 on which a further recommended step is to be implemented. The shortest path from the first treatment device 4 to the second treatment device 4 is represented in FIG. 3 by arrows which are displayed to the user A on the display device 7 dof the eyeglasses 7. Thus, a user A can quickly understand which route is to be selected in order to arrive as quickly as possible to another container treatment installation 4 in order to carry out a working step there. The target treatment device 4 is marked by an X as in FIG. 3. It is also conceivable for the user A to be guided to the target position by voice, sound and / or light signals.The present invention is not limited to the described embodiments. Further modifications and variations of the exemplary embodiments are conceivable. Thus, it would be possible for the position detection device 3 to be configured to record and store the paths of the user A and the state information and environmental constraints of the operation of the container treatment plant 1. The operation detection device 5 may be configured to record and store the environmental constraints and the operation state of the treatment devices 4 disposed on the path of the user A. This enables a complete documentation of the operation of the container treatment system 1 and the recommended working steps carried out for any subsequent processing and potential raw data for further simulations of the state simulation device 9 a.It is also conceivable for the control station 9 to list a plurality of operating recommendations and prioritize them according to importance, urgency or complexity. The respectively prioritized work step is relayed to the user on the operator assistance system 3. The following working steps can already be announced via the operator assistance system 3. Depending on the movement and position of the user A, working steps can be allocated dynamically to further users A that are positioned better.It is also conceivable that the path to a target treatment device 4 comprises intermediate targets. Thus, a user A can be guided past a supply station or workshop, for example, in order to be equipped accordingly for the recommended working step.Although the invention has been described with reference to specific embodiments for a complete and clear disclosure, the appended claims are not to be so limited, but are to be construed as embodying all modifications and alternative constructions that may adequately occur to one skilled in the art that fall within the scope of the claims. In addition, the features of various implementation embodiments may be combined to form further embodiments of the invention.List of reference characters1 Container treatment facility; 2 Operator assistance system; 3 Position detection device; 4 Treatment device; 5 Operator detection device; 6 Mobile operator assistance device; 7 Spectacles, augmented reality spectacles; 7a Spectacle frame; 7b Spectacle lens; 7c Spectacle arm; 7d Spectacle display device; 7d1, 7d2 Optical glass, head-mounted display; 8 Display device; 9 Control station; 9a State simulation device; 10 Data transmitter; 11 Hearing / speaking unit; 12 Gesture recognition unit; 13 Hearing protection; 14 First camera 15 Second camera A User B ContainerReferences included in the specificationThis list of documents cited by the applicant has been produced in an automated manner and is only included for the better information of the reader.
