Description

State of the art

[0001] A worker guidance system is proposed for guiding a worker during the execution of a process using a process system. The process system has at least one process device with process setup capabilities, wherein the process comprises at least one work step. The worker guidance system has a control device and a communication device, wherein the control device is configured to control the communication device based on process data and to communicate the work step to be performed to the worker.

[0002] In production, it is still common practice for some production steps to be performed manually by a worker. This is particularly widespread in small-batch production. Worker guidance systems are used to ensure quality and reduce training costs for the worker. However, today's production systems that use worker guidance are generally very rigid and focused on a specific selection of products. The worker guidance is programmed and configured for the specific work processes. With increasing variant diversity and simultaneously decreasing product lifespans, this rigid programming is disadvantageous. This can be particularly problematic in flexible production systems.

[0003] Document DE 10 2015 215 666 A1, which arguably represents the closest prior art, describes a tool, in particular a power tool, which has a display device and means for receiving and evaluating transmitted data. The tool is suitable and capable of displaying at least one piece of information, based on data transmitted by the tool and on the display device, that relates to or represents at least one work step to be performed, in particular, with the tool.

[0004] The publication DE 10 2005 005 266 A1 describes a method and a device for the automated generation and display of work instructions for the assembly of a product. Within the scope of the method, work steps for assembling the product are generated by a processing unit, design data is read out, and data for the visual representation of the parts is automatically generated from the design data. Based on this, work instructions are visually output. To generate the data for the visual representation of the tool, the processing unit accesses a resource memory with existing technical data.

[0005] EP 2 052 807 A1 discloses an assembly workstation for performing an assembly process with a tool. The assembly process describes an assembly workstation for performing an assembly process with a tool, wherein the assembly process comprises at least one assembly step and wherein the assembly workstation is connected to an assembly control system. A display for visualizing the upcoming assembly step and a database for storing the visualization data are connected to the assembly control system. The tool automatically determines the completion of the assembly step by connecting the tool to the assembly control system and transmitting the currently achieved assembly parameters to the assembly control system. Disclosure of the invention

[0006] A worker guidance system for guiding a worker is proposed, having the features of claim 1. Furthermore, a process system having the features of claim 12, a method having the features of claim 13, a computer program having the features of claim 14, and a machine-readable storage medium having the features of claim 15 are proposed.

[0007] A worker guidance system for guiding a worker is proposed. The worker guidance system is, in particular, a programmable, for example, reprogrammable, worker guidance system and, more specifically, a graphically programmable worker guidance system. The worker guidance system is designed to guide a worker in the execution of a process and / or multiple processes using a process system. The worker is, for example, a person who carries out the process. The process can be a production process, a machining process, or a measuring process. The worker guidance system is configured to give the worker instructions on which work steps are to be performed and in which manner, with the correct execution of the manually performed work steps being monitored, preferably with the aid of sensors. The process system is and / or comprises, for example, a workstation, a measuring station, or a production system.The process plant may be partially automated. In particular, the process plant is designed to allow for manual work steps by the operator.

[0008] The processing system is designed to manufacture, inspect, or machine a workpiece. Specifically, the processing system is designed for a wide range of workpieces. The processing system can preferably be modified and thus adapted to different workpieces.

[0009] The process plant has at least one process device with process device capabilities. For example, the process plant comprises exactly one process device, in particular more than three process devices, and especially more than ten process devices. The process devices are preferably designed to interact with the worker. For example, the process devices are tools for the worker. The process device capabilities are self-descriptions of the process device, which describe the capabilities, options, and / or processing steps enabled by the process device. Preferably, the process device capabilities are stored in the worker management system, for example, a central database. Alternatively, the process device capabilities can be stored in the process device. The process device capabilities are preferably stored once and / or initially, for example, by the manufacturer.

[0010] The process comprises at least one work step. Preferably, the process comprises multiple work steps, wherein in particular at least one work step is a manual work step performed by the worker. Preferably, the work step is performed using the process device. For example, the work step is machining or measuring the workpiece. In particular, the work step is, for example, drilling, grinding, or machining with a tool. Specifically, the work step is machining the workpiece using the process device. The process is preferably a production or inspection of the workpiece.

[0011] The worker guidance system has a control device and a communication device. The control device is, for example, a computer unit, a processor, or a computer chip. The control device can be a central control device. In particular, it can also be provided that the process device comprises the control device. Specifically, the process plant comprises the control device. The communication device can be a central communication device; alternatively and / or additionally, the communication device is comprised by the process device. The communication device can also be part of the process plant. The communication device is, for example, a display device, specifically a screen or lamps that can display positions.The communication device may also form an acoustic communication device, for example a loudspeaker for outputting announcements or another acoustic signal.

[0012] The control device is configured to control the communication device based on process data. In particular, the control device and the communication device are connected to each other via data technology. Based on the process data, the control device controls the communication device to communicate work steps to be performed to the worker according to the process. For example, the control device controls the communication device to indicate to the worker which work step, how, when, and / or where the worker is to perform it. For example, the communication device displays an image, a video, or text information on the work step to be performed on the screen. In particular, the process device capabilities can be displayed.Furthermore, it can be provided, for example, that the communication device indicates to the worker by means of illuminated lamps where he or she has to carry out a work step, for example with which tool and / or with which process equipment. Information that can be displayed about the work step to be carried out includes, for example, how a work step is to be carried out and which components are to be used. Furthermore, it is also possible to show the worker a reconfiguration of the process plant, the process equipment and / or other resources as information to be displayed and / or communicated. This includes, for example, information on how a process equipment can be dismantled and removed from the work area and / or the process plant. Furthermore, it is possible to communicate to the worker which process equipment is to be set up in the work area and how it is to be put into operation.The information to be communicated is controlled both by a process control system and by the processes themselves.

[0013] The process setup capabilities are provided to the control device as process setup capability data. For this purpose, the control device is connected and / or connectable to the process devices via data technology. The process data includes the process setup capability data. Thus, the control of the communication device for displaying and / or communicating the work step to be performed is also carried out, in particular, on the process setup capabilities. For example, the process setup capabilities include information, videos, and / or images, as well as how these are to be used. This information can be communicated to the worker directly and / or in a processed form via the communication device.For example, the process data also includes how a workpiece can be and / or is to be machined with the process device. By providing the process device capability data to the control device, this information can be communicated via the communication device for use with the process device. This results in a dynamic adaptation of the worker guidance, since information and / or data can be variably adapted based on the process device and / or the associated process device capabilities.

[0014] The worker guidance system thus enables flexible support of a versatile production plant, whereby even physically reconfigurable process plants can be easily adapted and / or orchestrated using the worker guidance system. Because the worker guidance system is dynamically designed, changes to workflows in the worker guidance system are not complex to program, as these adjustments can be easily compiled using the process setup capabilities. The engineering effort required to adapt the worker guidance system is thus reduced. The required production processes, for example, during product assembly, are modeled specifically as a linked structure or as a sequence of process setup capabilities and the individual parts and / or process resources involved.The control device can interpret work plans and autonomously adapt the communication device and / or communication of the processes and / or work steps, whereby the correct and / or necessary information is communicated to the worker.

[0015] It is particularly preferred that the process data comprise a process sequence. In particular, the process sequence comprises multiple work steps. For example, the process sequence is a sequence of multiple work steps, wherein the process sequence comprises the sequence, duration, and / or combination of work steps. The process sequence can comprise automatic, manual, and / or semi-manual work steps. In particular, it can be provided that the control device is designed to communicate the process sequence to the worker, for example, by means of the communication device. The process sequence can be communicated to the worker, for example, as a workflow.

[0016] Optionally, the process device capability data includes information about the work step to be communicated. For example, the process device is a screwing station, where the process device capability data includes the information to communicate to the worker that they should screw a screw into an object with a certain torque. The control device can access this information and communicate it to the worker via the communication device. Specifically, information about the work step to be communicated can also be stored in the process data and / or the process flow.

[0017] One embodiment of the invention provides that the control device is configured to select a process device suitable for the work step and / or process based on the process, the work step, the process sequence, and / or the process data. For example, the process is "screwing with torque X, pressing in component Y, and recording measured variable Z." The control device is configured to extract the work steps based on the process and / or the process sequence. In the above example, the work steps are "screwing," "pressing in," and "measuring Z." The control device is specifically configured to assign a process device to the work steps based on the process device capability data. In the above example, for example, a screwing station is assigned to the work step "screwing," a press is assigned to the work step "pressing in," and a measuring device is assigned to the work step "measuring Z."In particular, the.

[0018] It is particularly preferred that the control device is designed to start the process device and / or to control it to carry out the work step. In particular, the process device can have the work step and / or work step information implemented. If the work step is fully automated, for example, the process device can be controlled to carry out the process without worker instructions. If the work step is manual or semi-manual, the implementation can include instructions for the worker. For example, the implementation of the instructions can include controlling lights located in the process device to guide the worker. Furthermore, for example, an internal or external display can be controlled to guide the worker, wherein the process device itself in particular searches for and / or controls a display, a communication device or a communicable process device.If specific information, such as photos or value parameters, is required, the control device and / or the process device can preferably be configured to specify and / or determine the required parameters and / or data. Specific information can, in particular, be extracted from data sources, for example, from a model of the process, the workflow, and / or from an external data source. In particular, data and / or work steps to be communicated can be stored in the process device in text and / or image form.

[0019] One embodiment of the invention provides that the process involves the installation and / or use of a component. In particular, the process can comprise a work step for installing and / or using the component. The process data specifically comprises component information. The component information can comprise a component number, a component geometry, or a component photo. For example, the control device is designed to control the communication device based on the process data and to display an image and / or a component number of the component to the worker so that the worker knows which component to use. Furthermore, the process data can comprise information regarding the process parameters with which the component and / or the work step is to be carried out, for example the torque required, the processing temperature, and / or the measurement parameters provided.In particular, it can be provided that the worker guidance system can detect by sensors whether the worker has used the correct component, whereby this comparison can preferably be based on a comparison of the process data and / or the component information with sensor-detected data.

[0020] It is particularly preferred that the component information be provided by an ERP system. An ERP system stands for Enterprise Resourcing Planning System. The ERP system can be stored centrally in the worker guidance system or in the process system. Furthermore, it can be provided that the worker guidance system is connected to an external ERP system, whereby the component information is provided to the worker guidance system via the ERP system. The ERP system can, for example, provide the quantity and / or location of the component as component information to the worker guidance system.

[0021] One embodiment of the invention provides that the worker guidance system comprises a sensor device for monitoring the work step, the process and / or the production system. The sensor device is designed to provide sensor data. The sensor device is, for example, an optical sensor device, for example a camera device; alternatively, the sensor device can be a chip reader, a haptic sensor device or a sensor device for measuring electromagnetic properties. The process data particularly comprise the sensor data. For example, the sensor device is designed to detect whether the worker has processed a workpiece and / or whether a work step has been carried out by the worker. The carried out work step and / or the use of the component can be used as sensor data by the control device.The control device is then configured, for example, to continue the process flow and, for example, to communicate the next work step to the worker. In particular, the sensor device can also be an actuation switch, which, for example, is to be actuated by the worker once they have completed the work step. Thus, the worker guidance system and / or the control device can communicate the next instruction and / or next communication to the worker once sensory detection has detected that a work step has been successfully completed. If sensory detection is not possible, the worker can be prompted to acknowledge the work step.

[0022] It is particularly preferred that the process comprises at least two work steps. The two work steps can preferably be executed and / or carried out in a specific order within the process. The control device is preferably designed to control the communication device based on the process data, displaying the work steps of the process to the worker in the correct order for execution. For example, the work steps and / or the following work step are only displayed to the worker if the previous work step has been performed. For this purpose, the process data particularly includes the process flow.

[0023] One embodiment of the invention provides that the work steps can be represented and / or are designed as a sequence and / or as a linkage of process device capabilities. The process can, for example, be represented as a sequence of work steps. In particular, the process is stored in the control device as such a linkage and / or sequence of work steps. It is particularly preferred that the control device is designed to assign a process device to at least one work step. In particular, it can be provided that the worker guidance system is programmable, in particular graphically programmable, by the worker and / or a person to create a new process by linking work steps based on process device capabilities.After the process facility is modified by adding another process facility with stored process facility capabilities, a process can be created that includes a new work step that can be integrated into the sequence and / or the link. This provides a modular worker guidance system.

[0024] It is particularly preferred that the control device is configured to extract information to be communicated based on the process, the work step, the process sequence, the process device capabilities, and / or the process data and to display it via the communication device. For example, if a process is required for the manufacture of a product that is not currently available, a process device is determined that is to guide its disassembly. Following this disassembly, the control device can be configured to communicate to the worker which process device he or she should assemble.

[0025] It is particularly preferred that the worker guidance system comprises an input device. The input device is, for example, a keyboard, a touchscreen, or a voice control device. By means of the input device, it is provided in particular that the worker can set and / or specify process parameters. The process parameters are preferably based on the process device capabilities. For example, the worker and / or a person can set how a process device is to be used, in particular with which parameters. For example, the process device is a screw device, wherein the input device can be used to set which torque is to be used in the process and / or in the work step.

[0026] In particular, it can be provided that the worker guidance system comprises a feedback device, wherein the feedback device is designed to provide an actuation by the worker as worker data. The worker data is to be understood in particular as similar to the sensor data. The process data preferably comprises the worker data. By means of the worker data and / or the actuation of the feedback device, for example, a worker can inform the worker guidance system and / or the control device that they have performed a work step and / or a process. The actuation of the feedback device can, for example, signify an acknowledgment and / or the completion of a work step.

[0027] The worker guidance system can also be designed as a capability-based system in which the communication of the work step is modeled once, but the data, particularly process data, is integrated dynamically. For example, it is provided that the work steps are modeled as subordinate processes before the start of the process. In particular, it is provided that the process device provides its function as process device capability data, for example, "Set screw program with torque M" and / or "Confirm execution." Preferably, the communication device provides "Display worker command" as the function. The process and / or the workflow is preferably modeled by the control device in such a way that it accesses the functions provided by the process devices.For example, a process flow "Guided Screwing" is modeled from the provided functions: "Start", "ShowWorkerCommandC, Please screw in the component 'Bx' at the indicated location", "ComponentName X, Image)", "SetScrewingProgram(Ma) -> ConfirmExecution()", "End". The parameters of the modeled process are "Component Bx", Image, and Ma.

[0028] A further subject matter of the invention is a process plant. The process plant, in particular, has at least one process device. The process device, in turn, in particular, has process device capabilities. The process plant has a worker guidance system. In particular, the worker guidance system is designed as previously described. The worker guidance system is designed to communicate a work step to be performed to the worker when using the process plant. The control and / or communication of the work step to be performed is based, in particular, on process data. The process data, in turn, comprise the process device capabilities, in particular as process device capability data.

[0029] The invention further relates to a method for guiding a worker during the execution of a work step using a process system. A work step to be performed is communicated to the worker. The communication of the work step to be performed is based on process data. The process data includes process setup capability data. The process setup capability data includes process setup capabilities of process equipment. Process equipment includes, for example, modules, tools, and / or objects that the worker must use to perform the work step. For example, the process equipment is a drilling station, wherein the process setup capabilities include information that it is a drilling equipment and which speeds and / or torques can be adjusted.The communication of the work step may then include the display and / or communication of these process setup capabilities, for example the display of the possible and / or the speeds and / or torques to be used.

[0030] A further subject of the invention is a computer program which is designed to carry out all steps of the method described above when the computer program is used and / or executed on a computer unit and / or the worker guidance system.

[0031] A further subject of the invention is a machine-readable storage medium, wherein the computer program is stored on the machine-readable storage medium as described above.

[0032] Another subject matter of the invention not covered by the scope of protection is an electronic control unit, wherein the electronic control unit is designed to carry out all steps of the method.

[0033] Further advantages, effects, and configurations are evident from the attached figures and their descriptions. They show: Figure 1 an embodiment of a process plant; Figure 2 exemplary components of the process plant; Figure 3 Sequences in the flow of a process.

[0034] Figure 1shows an embodiment of a process plant 1. The process plant 1 comprises a worker guidance system 2. The process plant 1 has a work area 3. The work area 3 is designed here as a table area. A plurality of process units 4a, 4b and 4c are arranged in the work area 3. The process units 4a-4c are preferably designed for use by a worker 5. For example, the process device 4a is a drill, for example a cordless screwdriver, in particular with adjustable torque and / or adjustable speed. The process device 4b is, for example, a measuring device, for example a multimeter. The process device 4c is a tool for mechanically machining an object. By means of the process devices 4a-4c, a workpiece 6 can be manufactured, measured and / or machined. The workpiece 6 can be manufactured and / or machined in a partially automated process.The process is specifically the production of the workpiece 6 and comprises a work step to be performed by the worker 5. By means of the process system 1 and / or the process devices 4a-4c, different workpieces can be produced, machined, or measured. Thus, the process system 1 forms a variably deployable system for producing a workpiece portfolio. After the worker 5 has been trained for this portfolio, particularly for a new workpiece 6, the process system 1 comprises the worker guidance system 2.

[0035] The worker guidance system 2 has communication devices 7 and a control device 8. The communication device 7a is designed as a screen device and can display images, videos, and / or text to the worker 5. The communication devices 7b, 7c, 7d, and 7e are arranged in the work area 3. The communication devices 7b-7d are designed as LEDs and can provide information to the worker 5 by switching them on or off. The control device 8 is designed to provide the worker 5 with information about the work step to be performed and / or the process using the communication devices 7a-7d.

[0036] The process devices 4a-4c have process device capabilities. The process device capabilities are, in particular, a self-description of the process devices 7a-7c. For example, the process device capability includes information about which process device, for example, a drill or multimeter, is involved and which process parameters, for example, adjustable torque, the process device 4a-4c enables. The process device capabilities are provided to the control device 8 as process device capability data. The control device 8 is configured to display information about the work step to be performed to the worker 5 based on the process device capability data. For example, the work step to be performed is drilling a hole in the workpiece 6. The communication device 7b indicates to the worker 5 to use the process device 4a by lighting up.The position of the workpiece 6 to be drilled is displayed on the communication device 7a in the form of an image. Furthermore, the torque to be used can be displayed to the worker 5 on the communication device 7a as information. In particular, it is provided that after the work step has been completed, the next work step is displayed to the worker 5 via the communication device.

[0037] The process can provide a work step in which a component 9 is to be installed on the workpiece 6. The control device 8 can comprise component information, which in particular has a component number and / or component shape. The control device 8 can be designed to communicate information on the use of the component 9 to the worker 5 by means of the communication device 7, in particular 7a and / or 7d. For example, in the work step, a screw must be installed as a component 9 on the workpiece 6. In this case, the control device 8 controls the LED 7d so that the worker 5 knows that he has to use the components 9. Further information, for example a workpiece number, can be displayed to the worker 5 on the communication device 7a.

[0038] Figure 2shows a schematic diagram of a process plant 1 with its components and the process sequence 10. The process plant 1 has a communication device 7. The communication device 7 is designed, for example, as a display device. Furthermore, the process plant 1 has a feedback device 11, which is designed as a button. In this exemplary embodiment, the feedback device 11 is part of the communication device 7. Using the feedback device 11, the worker can communicate the completion of a work step and / or process and provide it to the control device 8.

[0039] The process system 1 further comprises a plurality of process devices 4a and 4b. The process device 4a is designed as a screwdriver. The screwdriver 4a can be used by the worker 5. The process device 4a has process device capabilities 12a. The process device capabilities 12a are used by the process device 4a to screw in a screw, install a bit, and / or remove a bit.

[0040] The process device 4b is designed as an automatic process device. The process device 4d is, for example, an automatic screwing station. The process device 4b has process device capabilities 12b. The process device capabilities 12b are, for example, screwing in a screw, removing a bit, and / or mounting a bit. The process device capabilities 12a and 12b are provided as process device capability data to the control device 8. The control device 8 is designed to display information for performing the work step to the worker 5 on the communication device 7, for example, displaying "mount the screw with the process device 4a."

[0041] Components 9 can also be provided in the process plant 1, which can be installed and / or consumed, for example, with the process devices 4a, 4b. For example, the components 9 are screws. The components 9 have component information 13. The component information 13 is, for example, an image of the component 9, the name of the component 9 and / or a component number. The component information 13 is provided to the control device 8 in data format. The control device 8 is designed, for example, to display information for carrying out the work step to the worker on the communication device 7 based on the process device capability data and the component information 13. For example, the display for the worker 5 is: install screw X using the process device 4a.

[0042] The control device 8 is designed as a computer unit. The control device 8 is designed to carry out and / or process a process sequence 10 of a process. In particular, the communication device 7 is controlled based on the process sequence 10. The process sequence 10 is shown here as a flowchart. In a first step, two components 9 are installed in a work step 14a. For example, in work step 14a, two components 9 are connected to one another. An intermediate product 15 is produced by means of work step 14a. The intermediate product 15 is further processed with another component 9 in a work step 14b. For example, in work step 14b, a screw is screwed into the intermediate product 15. The workpiece 6 is then created from work step 14b.The control device 8 is designed to display information for the work steps, in particular 14a and 14b, to the worker 5 regarding the execution of the work step. For work step 14a, for example, the worker is shown to connect the two components 9 to one another using the process device 4a, whereas for work step 14b the worker is shown to screw the screw 9 into the intermediate product 15 using the process device 4a.

[0043] Figure 3shows, by way of example, a sequence for the execution of a process with three work steps 14a, 14b, and 14c. In a first step 15, a control device 8 interprets and checks the work plan 10. In a step 16a and 16b, the communication device 7 is controlled to indicate to the worker 5 that a bit is to be mounted on the process device 4a. The execution of the further process sequence 10 is then paused until the worker 5 confirms in a step 17 that the work step 14a, the changing of the bit, has been completed. In a step 18a and 18b, the control device 8 is informed that the work step 14a has been completed. The process sequence 10 then continues to be executed.

[0044] Work step 14a is followed by work step 14b. Work step 14b provides for screwing using the process device 4a. In step 19, the process device 4a is controlled by the control unit 8 to release the actuation button. In step 20, the process device 4a releases the actuation button. The release of the actuation button 19 is followed by step 21, in which the communication device 7 is controlled to display information, for example an image, to the worker 5 showing how to screw. This image is displayed until step 22 is carried out by the worker and drilling takes place. In this process, the actuation of the process device 4a by the worker 5 is determined by sensors. The actuation in step 22 is transmitted to the control device 8 via data technology in step 23. Work step 14c follows step 23.For this purpose, in step 24, the process device 4b is controlled to perform a work step. The process device 4b is an automatic process device and does not require any activation by the worker 5. In step 25, the work step is thus performed automatically by the process device 4b. In step 26, the activation and / or completion of step 25 is communicated to the process device 8 via data technology.
