Description

[0001] Method and device for recording measurement data of a machine and tire heating press comprising a device for recording measurement data

[0002] The invention relates to a method and a device for recording measurement data of a machine.

[0003] Furthermore, the invention relates to a tire heating press comprising at least one device for recording measurement data of a machine.

[0004] The invention comprises, in embodiments, a digital application for machines, in particular for tire curing presses.

[0005] Conventional tire curing presses already feature a digital control system that can be used to control the individual process steps, which vary depending on the machine's configuration. In addition, many conventional tire curing presses also feature an evaluation unit that can detect certain functions or malfunctions of the tire curing press and generate corresponding machine messages.

[0006] For known tire curing presses, these machine messages must be read and interpreted manually by the user, operator or maintenance personnel.

[0007] For production machines, including tire curing presses, it is generally important to achieve the shortest possible process runtimes to enable high throughput. The process runtime is specified for a specific machine configuration and is maintained within a certain tolerance range when a new or wear- and defect-free machine is commissioned according to specifications.

[0008] However, during the operation of a machine, wear and tear on the wear-prone assemblies or components as well as possible defects occur, which have a negative impact on the achievable process runtime.

[0009] Furthermore, it is generally important for production machines, including tire curing presses, to achieve the lowest possible media consumption in order to enable efficient media use.

[0010] The media consumption, for example in the form of the (electrical) energy required for a process run, the compressed air, the oil or hydraulic oil, nitrogen, steam or hot water, is specified for a certain machine and process specification and is maintained within a certain tolerance range when a new or wear- and defect-free machine is commissioned according to the specifications.

[0011] However, with the operation of a machine, wear and tear on the wear-prone assemblies or components as well as defects may occur, which can have a negative impact on the achievable media consumption.

[0012] It is therefore an object of the invention to provide a device for recording measurement data of a machine and a tire curing press which solves at least some of the aforementioned problems.

[0013] This object is achieved according to the invention by a device for recording measurement data of a tire heating press according to patent claim 1 and a tire heating press according to patent claim 11.

[0014] A further object of the invention is to provide a method for acquiring measurement data of a machine which solves at least some of the aforementioned problems.

[0015] This object is achieved according to the invention by a method for recording measurement data of a tire heating press according to patent claim 12.

[0016] Advantageous aspects of the invention are claimed in the dependent claims. The features disclosed below of a device for acquiring measurement data from a machine, a tire curing press, and a method for acquiring measurement data from a machine are part of the invention in all feasible combinations.

[0017] In embodiments of the invention, a digital solution for the condition monitoring of machines, in particular tire curing presses, tire building machines, mixing machines, e.g. for rubber, or for machines from food and / or edible oil production, is realized.

[0018] A device according to the invention for detecting measurement data of a machine is designed to monitor at least one machine and comprises at least one detection device for detecting at least one machine parameter of the at least one monitored machine and at least one evaluation unit.

[0019] In embodiments of the invention, at least one media consumption of the at least one monitored machine can be recorded as a machine parameter using the at least one recording device.

[0020] In advantageous embodiments of the invention, at least one media consumption can be recorded in a time-dependent manner using the at least one recording device.

[0021] In embodiments of the invention, the at least one evaluation unit is designed to retrieve and evaluate the consumption of at least one consumable medium of the at least one monitored machine.

[0022] In embodiments, the consumption of the following exemplary consumables can be retrieved using the evaluation unit: the electrical energy required for a cycle or a subcycle, the amount of compressed air, oil or hydraulic oil, nitrogen, water, steam or hot water required.

[0023] In advantageous embodiments of the invention, target values ​​for the at least one media consumption that can be retrieved in the respective configuration can be retrieved using the at least one evaluation unit, and the recorded media consumption can be compared with the target values. If a consumption value lies outside of any defined tolerances around the target value, a consumption deviation can be detected using the at least one evaluation unit. The deviation of at least one media consumption from the target values ​​may be an indicator of specific causes, errors, or defects.

[0024] In advantageous embodiments of the invention, a list of causes can be called up for various consumption deviations or combinations of consumption deviations using the at least one evaluation unit so that the cause, the error or the defect can be automatically and clearly identified or the list of causes can at least be automatically further restricted using the at least one evaluation unit.

[0025] The at least one evaluation unit of the device according to the invention for recording measurement data of a machine is designed for monitoring the condition of the at least one monitored machine based on the at least one media consumption recorded by the at least one recording device.

[0026] The time-dependent recording of media consumption allows the allocation of consumption deviations to individual process steps of at least one monitored machine.

[0027] In preferred embodiments of the invention, condition monitoring within the meaning of the invention is the specific condition monitoring of the at least one monitored machine as a whole, as well as at the assembly and / or functional level. Condition monitoring is particularly preferably implemented at the component level.

[0028] The at least one evaluation unit is designed for condition monitoring, preferably for retrieving stored target values, tolerances and / or limit values ​​of at least one media consumption.

[0029] For example, it is designed to retrieve the target values ​​from a local storage device as part of the device for recording measurement data and / or from an external data storage device, for example as part of a cross-machine database at a production site or in the cloud. Preferably, an associated tolerance range or limit value is retrieved for each of the at least one media consumption values. In principle, it is also possible according to the invention for only the tolerance ranges and / or limit values ​​of all media consumption values ​​to be retrieved. Furthermore, the at least one evaluation unit is designed to compare the at least one recorded actual media consumption value with the target values ​​and / or the tolerance ranges or the limit values ​​for the target values.

[0030] If at least one recorded media consumption falls outside the tolerance range of the target values ​​defined for the overall process and / or the respective process step or exceeds or falls below the respective limit value, the at least one evaluation unit is designed to detect a consumption deviation.

[0031] In embodiments of the invention, the at least one evaluation unit is designed to generate a deviation signal upon detection of a consumption deviation, which signals the deviation of at least one detected media consumption.

[0032] In embodiments of the invention, the at least one evaluation unit is designed to output the at least one deviation signal upon detection of a consumption deviation.

[0033] Preferably, the deviation signals are individually identifiable according to the respective media consumption, so that the deviation signal can be used to determine which media consumption deviates from the target value(s).

[0034] In embodiments of the invention, a deviation message can be generated with the aid of the at least one evaluation unit depending on the individual deviation between target and actual consumption, which at least identifies the deviating media consumption.

[0035] In embodiments of the invention, the evaluation unit is designed for the automated detection of at least one cause underlying the consumption deviation or at least for the automated limitation of the possible causes.

[0036] By assigning media consumption to specific process steps or machine movements, it is possible to narrow down the possible causes to those that influence the media consumption of the respective subcycle based on the identification of the deviating media consumption.

[0037] In advantageous embodiments of the invention, cause lists associated with the individual media consumptions can be retrieved with the aid of the at least one evaluation unit, which lists contain the various possible causes for the respective consumption deviation.

[0038] Causes for a deviation in media consumption can include wear and tear, defects, incorrect settings, material and / or production defects.

[0039] Preferably, each cause listed in the list of causes is assigned at least one criterion, whereby the examination of the presence or absence of the at least one criterion can be used to determine whether the respective cause applies or can apply.

[0040] In embodiments of the invention, the at least one evaluation unit with the deviation signal and / or the deviation message is designed to output the respective cause list and / or criteria list.

[0041] By collecting additional data, the cause can be clearly identified from the list of causes or the list of causes can at least be further narrowed down.

[0042] Compared to the primary collection and analysis of machine alarm and fault messages, monitoring a machine's media consumption offers the advantage of being able to detect previously unnoticed, gradual deteriorations in the machine process ("process drift") very early on. Furthermore, monitoring media consumption, especially time-resolved monitoring of media consumption, can support the search for the cause of an error message if it is unclear.

[0043] In advantageous embodiments of the invention, the at least one evaluation unit is designed to retrieve additional data in the event of a detected consumption deviation, by evaluating which, in conjunction with the detected consumption deviation, the cause can be automatically identified or at least further narrowed down.

[0044] In embodiments of the invention, the at least one evaluation unit is designed to correlate the detected consumption deviations with the additionally retrieved data.

[0045] In embodiments of the invention, the additionally retrievable data includes sensor data and / or machine messages and / or recorded cycle or subcycle times, each relating to the at least one monitored machine and / or corresponding machines. By evaluating sensor data, which may be provided by machine-related measured values, machine messages and / or cycle or subcycle times, criteria for the presence or absence of certain causes for the consumption deviation(s) can be verified in corresponding embodiments of the invention with the aid of the at least one evaluation unit.

[0046] In embodiments of the invention, the at least one evaluation unit is designed to automatically generate suggestions for eliminating the cause based on the determined cause or the determined possible causes for the at least one detected deviation and / or to carry out an automated cause elimination and / or to issue suggestions or instructions for further cause determination.

[0047] The sensory monitoring of the at least one machine, for example a tire curing press, implemented in embodiments of the invention is realized by means of at least one sensor arranged to acquire data relating to the at least one monitored machine.

[0048] The at least one sensor can be an integral part of the at least one machine to be monitored or a sensor arranged in, on or in the area of ​​the at least one machine to be monitored as part of the device for recording measurement data.

[0049] As such a sensor, in various embodiments of the invention, for example, at least one of the following sensors is arranged for corresponding use: pressure sensor and / or flow sensor (e.g. for steam, air, nitrogen or hydraulic oil) and / or sensor for measuring electrical voltages, currents or power and / or vibration sensor and / or temperature sensor and / or particle monitor and / or humidity sensor and / or viscosity sensor and / or imaging sensor and / or speed sensor and / or acceleration sensor and / or force sensor and / or sensor for determining valve states.

[0050] In embodiments of the invention, the evaluation unit is designed to retrieve and evaluate the sensor data (measured values) of at least one sensor that is arranged to acquire data relating to the at least one monitored machine.

[0051] In embodiments of the invention, the evaluation unit is designed to retrieve and evaluate the sensor data (measured values) when a consumption deviation occurs. This event-based data retrieval ensures smaller data volumes to be processed compared to continuous retrieval.

[0052] In other embodiments of the invention, the at least one evaluation unit is designed to continuously retrieve the sensor data. Continuous data retrieval provides a comprehensive database that can be used, for example, with the help of artificial intelligence (AI) and / or machine learning (ML) to predict the machine condition.

[0053] A combination of the retrieval of sensor data when a consumption deviation occurs for a first group of sensor data comprising at least the sensor data acquired using a sensor with a continuous retrieval of the sensor data of a second group of sensor data is also possible in embodiments of the invention.

[0054] In advantageous embodiments of the invention, target values ​​can be retrieved for the sensor data acquired in the respective configuration using the at least one evaluation unit, and the acquired sensor data can be compared with the target values. If a measured value lies outside of any defined tolerances around the target value, a measured value deviation can be detected using the at least one evaluation unit.

[0055] The deviation of the measured values ​​of one or more sensors from the target values ​​may be an indicator of specific causes, errors or defects.

[0056] In advantageous embodiments of the invention, a list of causes can be called up for various measured value deviations or combinations of measured value deviations using the at least one evaluation unit so that the cause, the error or the defect can be automatically and clearly identified or the list of causes can at least be automatically further restricted using the at least one evaluation unit.

[0081] In embodiments of the invention, the at least one evaluation unit is designed to retrieve and evaluate machine messages from the at least one monitored machine.

[0082] Machine messages are messages that are usually automatically generated by the control system of the respective machine, depending on its status. Alarm and / or fault messages are particularly such machine messages, but they can also include general status messages, for example.

[0083] Depending on the monitored machine and the machine software / PLC software, this can be between 500 and 1,500 different machine messages. These messages are currently not standardized in their type and error code and depend on individual customer specifications and the respective machine control system. In preferred embodiments of the invention, these machine messages are so precise and specific that the user can directly determine the cause / source of the error and, if necessary, even receive instructions for action.

[0084] In embodiments of the invention, the at least one evaluation unit is designed to retrieve and evaluate machine messages from the at least one monitored machine when a consumption deviation occurs.

[0085] In other embodiments of the invention, the at least one evaluation unit is designed to continuously retrieve the machine messages of the at least one monitored machine. Continuous data retrieval provides a comprehensive database that can be used, for example, with the aid of AI and / or ML, to predict the machine's condition.

[0086] A combination of the retrieval of machine messages when a consumption deviation occurs for a first group of machine messages with a continuous retrieval of the machine messages of a second group is also possible in embodiments of the invention.

[0087] In embodiments of the invention, the at least one evaluation unit is designed to count and store the frequency of occurrence of at least one specific machine message. Depending on the machine message and its frequency or the frequency trend, this is an indicator of the need for maintenance measures in embodiments of the invention.

[0088] In embodiments of the invention, the at least one evaluation unit is designed to determine and / or store the maximum, minimum and / or average duration of the occurrence of specific machine messages, the assignment of machine messages to a specific product ID and / or the assignment of machine messages to specific assemblies or parts of the at least one monitored machine.

[0089] In embodiments of the invention, the cycle time required for carrying out a process cycle can be recorded as a machine parameter in addition to the at least one media consumption by means of the at least one recording device.

[0090] In advantageous embodiments of the invention, at least one subcycle time corresponding to the duration of a defined process step or a defined sequence of process steps can be detected by means of the at least one detection device.

[0091] Preferably, the cycle time required for carrying out a process cycle and at least one sub-cycle time can be recorded using the at least one recording device.

[0092] In preferred embodiments of the invention, the process cycle is divided into subcycles, each subcycle corresponding to a defined machine movement or a sequence of machine movements.

[0093] In particularly advantageous embodiments of the invention, the duration of each of the defined subcycles can be detected by means of the at least one detection device.

[0094] To record the cycle and / or subcycle times, the at least one recording device is designed to retrieve data from the machine control system and / or to evaluate machine messages and / or to monitor the respective machine using sensors.

[0095] The machine control of the at least one monitored machine specifies the start time of a cycle or sub-cycle, for example, with a control command and detects the end time of a cycle or sub-cycle based on a measured value, for example in the form of the activation of a switch / button when a certain position is reached, to which it reacts with a further control command to start the next process step.

[0096] In corresponding embodiments with the retrieval of data from the machine control, the at least one detection device is designed, for example, to detect a first cycle or subcycle time by measuring the time between a first control command that initiates the first cycle or subcycle and a second control command that initiates the next, second cycle or subcycle, or a detected event that signals the end of the first cycle or subcycle.

[0097] In addition, certain machine messages can also correspond to the start or end of a cycle or subcycle, so that the detection of a corresponding machine message using the at least one detection device can define the start or stop time of a cycle or subcycle.

[0098] Furthermore, in embodiments of the invention, the start and end of cycles or subcycles can be detected by sensory monitoring of the at least one monitored machine. For example, the start and end of certain process steps can be detected using imaging monitoring of the at least one machine, particularly when movements are involved.

[0099] In various embodiments of the invention, the above-mentioned ways of detecting cycle and / or subcycle times are combined in all possible options.

[0100] In embodiments of the invention, the at least one evaluation unit is designed to retrieve and evaluate the cycle and / or subcycle times of the at least one monitored machine.

[0101] In embodiments of the invention, the evaluation unit is designed to retrieve and evaluate the cycle and / or subcycle times when a consumption deviation occurs.

[0102] In other embodiments of the invention, the at least one evaluation unit is designed to continuously retrieve the cycle and / or subcycle times.

[0103] A combination of retrieving the cycle and / or subcycle times when a consumption deviation occurs for a first group of cycle and / or subcycle times with a continuous retrieval of the cycle and / or subcycle times of a second group of cycle and / or subcycle times is also possible in embodiments of the invention.

[0104] In advantageous embodiments of the invention, target values ​​for the cycle and / or subcycle times that can be retrieved / detected in the respective configuration can be retrieved using the at least one evaluation unit, and the cycle and / or subcycle times can be compared with the target values. If a cycle and / or subcycle time lies outside any defined tolerances around the target value, a time deviation can be detected using the at least one evaluation unit.

[0105] The deviation of at least one cycle and / or subcycle time from the target values ​​may be an indicator of specific causes, errors or defects.

[0106] In advantageous embodiments of the invention, a list of causes for various time deviations can be called up with the aid of the at least one evaluation unit so that the cause, the error or the defect can be automatically and clearly identified with the aid of the at least one evaluation unit or the list of causes can at least be automatically further restricted.

[0107] In embodiments of the invention, the device for acquiring measurement data of a machine has at least one communication device for connecting to at least one additional data source and / or for transmitting data to a higher-level storage and / or evaluation unit, which is / are preferably designed for data storage and / or evaluation for several machines.

[0108] In embodiments of the invention, additional data sources are, for example, other machines, preferably of the same machine type, which are, for example, identical or almost identical in construction, processes or devices arranged along the value chain upstream or downstream of the at least one monitored machine, a central storage and / or evaluation unit which, for example, has greater resources for carrying out extensive data evaluations or can access a larger amount of data, design data of the at least one monitored machine and / or the CAD model of the at least one monitored machine.

[0109] The central storage and / or evaluation unit can be implemented, for example, on a local server, in particular at the installation site (e.g., production site) of the at least one monitored machine, and / or on a cloud server. The use of a central storage and / or evaluation unit eliminates additional data processing capacity on each individual machine and, in embodiments of the invention, enables the results of the data evaluation to be displayed via mobile data technology regardless of location, as well as local, regional, or global benchmarking of various monitored machines.

[0110] In embodiments of the invention, the at least one evaluation unit is designed to carry out a benchmark - i.e. the data comparison of several monitored machines (e.g. tire curing presses) locally in a plant, regionally for several plants and globally across many / all plants.

[0111] This offers the following advantages for the operator or manufacturer of the monitored machines:

[0112] From the (local or global) comparison with identical machines, conclusions about the machine's condition can be drawn, possibly taking the respective product configuration into account. In embodiments of the invention, this happens automatically.

[0113] Conclusions about possible design and / or process improvements can be drawn from the (local or global) comparison with machines of other designs, possibly taking into account the respective product configuration. In embodiments of the invention, this occurs automatically.

[0114] From derived productivity and availability values ​​and their local, regional, or global comparison, conclusions can be drawn about a factory's performance. These values ​​can be made accessible to different user groups in an anonymized form, based on differentiated access rights. In embodiments of the invention, this occurs automatically.

[0115] The integration of upstream process steps in product manufacturing (e.g. mixer, extrusion and tire construction in tire manufacturing) and downstream process steps (including quality control) can be used in embodiments of the invention with the aid of the at least one evaluation unit for diagnosing the machine condition and / or the product quality of the individual product (e.g. tires).

[0116] In embodiments of the invention, for example, the tire structure is specified by information on the dimensions of the (green) tire (e.g., diameter and width), the weight, the composition of the rubber compound(s) of the green tire, and / or the (layer) structure of the green tire, and can be retrieved from a data source using the at least one evaluation unit. This allows, for example, the specified weight of the green tire to be considered as an influencing factor on media consumption.

[0117] By way of example, in corresponding embodiments of the invention, a feedback loop from the quality control to a monitored tire curing press is established in order to provide a basis for the effects of the process parameters of the tire curing press on the product quality.

[0118] By integrating the further process steps of the value chain, product-related data can be made available in embodiments of the invention, taking the entire value chain into account.

[0119] For example, in corresponding embodiments of the invention, the energy and / or material requirements for the production of a tire can be identified. The data basis can, in turn, be used for maintenance management to optimize machine operation and / or troubleshoot and / or further develop the manufactured product.

[0120] Furthermore, in embodiments of the invention, machine learning methods and / or artificial intelligence are applied to the process- and machine-relevant data of the entire value chain, for example, to be able to determine a prognosis regarding the product quality of a tire based on process data. Accordingly, in corresponding embodiments of the invention, the need for quality assurance measures at the end of the value chain can be reduced.

[0121] In embodiments of the invention, condition monitoring with condition prediction is realized with the aid of the evaluation unit and the data evaluated by the evaluation unit over time in the interaction of condition parameters and the operating behavior in certain situations via statistical methods / predictions.

[0122] In embodiments of the invention, the at least one evaluation unit is configured to apply artificial intelligence (AI) and / or machine learning (ML) methods to the retrievable data. By evaluating large amounts of data, correlations between changes and / or trends in individual data and the occurrence of specific error causes can be determined, so that, in embodiments of the invention, future states of the at least one monitored machine can be predicted. In embodiments of the invention, this enables early issuance of warning messages regarding impending defects and / or required maintenance.

[0123] In embodiments of the invention, the state of the at least one monitored machine, for example a tire curing press, can be displayed in a digital application (app).

[0124] In embodiments of the invention, the determined indicators can be output as a visual display using digital devices. Digital devices in this sense include, for example, smartphones, smartwatches, tablets, notebooks, PCs, or digital display boards.

[0125] In embodiments of the invention, current alarm and / or fault messages for a machine can be output in an overview including symbolic criticality, message designation and time stamp.

[0126] In embodiments of the invention, details of individual alarm and / or fault messages for a machine can be displayed with a name, description, solution instructions, references to the same message on other machines with a time stamp and / or link to the product produced under fault conditions (e.g., tire ID).

[0127] In embodiments of the invention, a message overview of several monitored machines (e.g. tire curing presses) can be output in an overview with a symbol for criticality, designation, machine location (“trench”), machine number and / or time stamp.

[0128] By comparing and simultaneously displaying fault messages from multiple machines (e.g., tire curing presses) in a factory, maintenance management is provided with a maintenance control center in embodiments of the invention, which makes the currently required maintenance measures for all monitored machines (e.g., tire curing presses) transparent. Based on this data, priorities for maintenance and repair can be derived, and related faults of multiple machines can be identified against the background of the shared infrastructure (e.g., group hydraulics, heating media, etc.).

[0129] In preferred embodiments of the invention, the media consumption of the last, for example, approximately 10 production cycles of a monitored machine or a monitored group of machines (e.g., heating press or group of heating presses, e.g., trench / entire heating room), which can be flexibly adjusted as needed, can be displayed as an overview during operation and related to the specification of the tire produced. If the actual media consumption is higher than the target value, the deviation and, if necessary, optional information for monitoring and / or optimally adjusting relevant assemblies or individual functions can be output as a message. Precise threshold values ​​and tolerance ranges for the monitored machine parameters can be defined for the respective machine configuration. The reporting function can be (de-)activated. In embodiments of the invention, the operating data for the relevant assemblies or individual functions can be displayed in detail.

[0130] In advantageous embodiments of the invention, improvement measures for the at least one monitored machine can be automatically proposed with the aid of the at least one evaluation unit based on the evaluated data.

[0131] With this approach, in embodiments of the invention, for example, machine performance can be improved by keeping media consumption, for example of tire curing presses, stable and low in order to increase productivity.

[0132] In embodiments of the invention, early warnings can be generated based on evaluated data using the at least one evaluation unit, which increase machine availability by avoiding unplanned downtimes, supporting repair and maintenance measures and / or reducing spare parts consumption.

[0133] In embodiments of the invention, the digital solution approach enables the energy consumption of at least one monitored machine, for example a tire curing press, to be displayed in production and thus made accessible to a user or operator of the machine for measures to improve energy consumption / the CO2 footprint.

[0134] The invention enables the following advantages in embodiments, or has the following features individually or in combination:

[0135] Optimizing machine performance, monitoring and stabilizing the cycle time of machines, e.g., tire curing presses, at a low level, issuing early warnings when media consumption exceeds a certain threshold, indicating causes of a continuous and gradual increase in media consumption, such as undetected leaks, wear, or incorrect settings, reducing actual media consumption per cycle, and increasing the productivity of a tire curing press by approximately 600-1800 tires per year (+1-3%). In embodiments of the invention, improved machine availability is enabled. This is made possible in particular by the following measures, individually or in feasible combinations:

[0136] Reducing unplanned downtime through early warning of incidents such as leaks, wear and tear,

[0137] Avoidance of unnecessary cooling and preheating by reducing unplanned downtime,

[0138] Reducing repair times by identifying the causes of errors and thus supporting targeted countermeasures,

[0139] Reducing planned maintenance times by focusing the actions on problems that need to be resolved,

[0140] Optimization of spare parts consumption through condition-based replacement of spare parts,

[0141] Reducing operating costs by reducing repair and maintenance times and by avoiding idle costs,

[0142] Reducing energy costs through real-time monitoring and reducing unnecessary energy consumption,

[0143] Overall, a reduction in costs per vulcanized tire of 1-3%.

[0144] In embodiments of the invention, intelligent tire vulcanization is realized. In embodiments of the invention, the so-called "smart curing" includes data exchange with tire curing presses throughout the entire curing area, as well as the necessary database for recording production and process data. This system enables simultaneous production monitoring, traceability, recipe management, and analysis of the tire curing presses.

[0145] In embodiments of the invention, a control loop is implemented which intervenes in the machine control system depending on the detected consumption deviation or the identified cause of the consumption deviation (e.g., automatic provision of digital parameters in the machine PLC, change of configurations) or uses mechanical actuators for targeted intervention in the system to be controlled, so that a "self-healing" tire curing press is realized.

[0146] Areas of application include production monitoring (e.g. production plan vs. actual, OEE, TCO), process monitoring (e.g. vulcanization data acquisition, recipe management, quality assurance), machine monitoring (e.g. condition monitoring, predictive maintenance, alarm diagnostics, machine service), energy monitoring (e.g. electrical power, compressed air, oil).

[0147] Applied technology / methods in embodiments of the invention include, for example, sensor technology, actuator technology, PLC programming and control, IT networking of machines (e.g., tire curing presses), edge / fog, edge / fog computing, HoT gateways, internet connection / protocols, cloud technology, data analysis, mobile application, machine learning algorithms / artificial intelligence, virtual reality and / or augmented reality.

[0148] According to the inventive digital solution approach for the condition monitoring of machines (e.g. tire curing presses), it is possible in embodiments of the invention to display the condition of a machine in a digital app and to automatically suggest improvement measures to the operating and maintenance personnel, as well as to enable technologically self-healing, self-regulating measures of the machine in production.

[0149] Areas of application include, for example, production monitoring (e.g. keeping the media consumption of tire curing presses consistently low in order to increase productivity by outputting deviations between predetermined target and measured actual values ​​of (sub-)phases of the tire vulcanization process), process monitoring (e.g. displaying quality defects in the tire vulcanization process based on machine alarm messages and machine parameters, whereby the monitoring of media consumption offers support in preventing previously unnoticed process deviations that would otherwise lead to a continuous increase in media consumption), machine monitoring and controlling (e.g. by correlating consumption deviations with machine parameters and / or fault messages. In this way, indications of the causes of faults can be automatically derived and suggestions for troubleshooting can be made automatically.

[0150] In embodiments of the invention, a digital maintenance tool for machines (e.g. for tire curing presses) is realized.

[0151] In embodiments of the invention, a method and a device for the efficient and effective maintenance of machines (e.g., tire curing presses) are implemented. In embodiments of the invention, the method and device are based on the principles of digital condition monitoring and / or artificial intelligence.

[0152] In embodiments of the invention, the at least one evaluation unit is designed to detect wear or defects in at least one assembly, such as the hydraulic unit, the pneumatic system, a loading and / or unloading device, a closing unit or a safety scanner.

[0153] In preferred embodiments of the invention, the at least one evaluation unit is designed to detect wear or defects of at least one component as such or as a component of an assembly, such as a shock absorber, hydraulic cylinder, motor, a line (leakage / blockage) or a sensor.

[0154] In embodiments of the invention, the at least one evaluation unit is designed to detect wear or defects in at least one hydraulic unit. For this purpose, the evaluation unit in embodiments of the invention is designed to record media consumption that is directly or indirectly influenced by the state of the hydraulic unit, and / or to record the hydraulic pressure using at least one pressure sensor, and / or to evaluate machine messages and / or the control parameters (configuration) relating to the hydraulic unit.

[0155] In embodiments of the invention, the at least one evaluation unit is designed to detect defects and / or wear in the pressure regulator of at least one hydraulic unit. If the pressure regulator of the hydraulic unit is defective or worn, a different, usually reduced, pressure is provided instead of the target pressure. This slows down hydraulically implemented movements of the machine, so that the corresponding cycle and / or subcycle times become longer.

[0156] In embodiments of the invention, the at least one evaluation unit can be used to retrieve a list of causes based on a detected consumption deviation with a possible cause in the hydraulic system, for example, comprising the causes of wear of the hydraulic unit, leakage in the hydraulic system, faulty control of the hydraulic unit, faulty setting of the hydraulic system and wear of the hydraulic cylinders.

[0157] In order to automatically narrow down the at least one cause underlying the at least one detected deviation, in advantageous embodiments of the invention, criteria for the individual possible causes can be retrieved and preferably checked automatically using the at least one evaluation unit.

[0158] For example, in embodiments of the invention, one or more of the following criteria can be called up and preferably checked: pressure in the pressure line of the hydraulic unit, electrical parameters (currents, voltages, power consumption) at the hydraulic unit, temperature of the hydraulic oil, oil level of the hydraulic unit, flow in the hydraulic line of the hydraulic unit (leakage detection), vibrations at the motor of the hydraulic unit, machine messages for timeouts for hydraulic movements or hydraulic oil temperature warnings, data from the upstream and / or downstream value chain.

[0159] Based on the overview of the criteria that are met or not met, in corresponding embodiments of the invention, the at least one cause can be clearly determined in an automated manner with the aid of the at least one evaluation unit, or the list of causes can at least be further reduced.

[0160] In embodiments of the invention, the at least one evaluation unit is designed to detect defects and / or wear in the clamping unit of a tire curing press. In embodiments of the invention, a defect / wear in the clamping unit can be detected by evaluating the cycle and / or subcycle times and / or by monitoring the energy consumption of the hydraulic unit and / or by evaluating machine messages.

[0161] In embodiments of the invention, the at least one evaluation unit can be used to retrieve a list of causes based on a detected consumption deviation with a possible cause in relation to the closing unit, for example comprising the causes of missing lubrication of sliding plates or mold segments of the tire mold, hydraulic leakage at the segment mold actuation, incorrect control of the hydraulic function for closing the press (configuration), incorrect setting of the hydraulic function for closing the press (for example setting of the pressure relief valve).

[0162] For the automated localization of the at least one cause underlying the at least one detected deviation, in advantageous embodiments of the invention, criteria for the individual possible causes can be retrieved and preferably automatically verified using the at least one evaluation unit. For example, in embodiments of the invention, one or more of the following criteria can be retrieved and preferably verified: pressure in the pressure line of the hydraulic unit, provided hydraulic closing pressure, electrical parameters (currents, voltages, power consumption) at the hydraulic unit, temperature of the hydraulic oil, flow in the hydraulic line of the hydraulic unit (leakage detection), oil level of the hydraulic unit, vibrations at the motor of the hydraulic unit, machine messages regarding the timeout for the closing process, and data from the upstream and / or downstream value chain.

[0163] Based on the overview of the criteria that are met or not met, in corresponding embodiments of the invention, the at least one cause can be clearly determined or the list of causes can at least be further reduced using the at least one evaluation unit.

[0164] In embodiments of the invention, the at least one evaluation unit is designed to detect defects and / or wear of the safety scanner of at least one machine.

[0165] For example, contamination of the safety scanner on machines designed as tire curing presses leads to irregular machine downtimes. If such a machine downtime occurs during tire vulcanization, it usually results in an overcured tire and thus in rejects.

[0166] In embodiments of the invention, the at least one evaluation unit is designed to detect a defect and / or wear of the safety scanner of at least one machine by evaluating machine messages.

[0167] In embodiments of the invention, the at least one evaluation unit is designed to detect a connection interruption of at least one sensor of at least one machine.

[0168] Sensor connections can be interrupted, for example, if the sensor cable breaks.

[0169] In embodiments of the invention, the at least one evaluation unit is designed to detect a connection interruption of at least one sensor of at least one machine by evaluating machine messages and / or evaluating media consumption.

[0170] In embodiments of the invention, the at least one evaluation unit is designed to identify required maintenance measures.

[0171] In embodiments of the invention, the at least one evaluation unit is designed to evaluate machine messages and / or to evaluate the current process step in the process cycle.

[0172] For example, the at least one evaluation unit is designed to evaluate the machine messages for a release signal, particularly in a tire curing press, and to compare the release signal with the current process step of the process cycle. If the release signal is not detected during the vulcanization process step, a machine malfunction has occurred.

[0173] In embodiments of the invention, the at least one evaluation unit is designed to monitor downtimes of at least one machine. The development of downtimes, in particular their increase, is also an indicator of the need for maintenance measures in embodiments of the invention.

[0174] In embodiments of the invention, the at least one evaluation unit is designed to monitor sensor signals and / or messages of the safety system of at least one machine.

[0175] In embodiments of the invention, the at least one evaluation unit is designed to evaluate light barrier signals. Light barriers are often used to secure safety zones around machines, for example, around tire curing presses. As soon as a light barrier is triggered, the machine stops.

[0176] Corresponding triggering of the safety system can be visualized with the help of the invention via machine messages and / or cycle interruptions and / or interruptions in media consumption.

[0177] In embodiments of the invention, the at least one evaluation unit is designed to detect defects and wear of at least one pneumatic unit. For this purpose, the evaluation unit in embodiments of the invention is designed to record media consumption that is directly or indirectly influenced by the state of the pneumatic unit, and / or to record the pneumatic pressure using at least one pressure sensor, and / or to evaluate machine messages relating to the pneumatic unit.

[0178] In embodiments of the invention, the at least one evaluation unit is designed to detect defects in the compressed air supply of the pneumatic system of at least one machine. For this purpose, in preferred embodiments of the invention, the evaluation unit is designed to monitor the pressure in the pneumatic system and / or in the compressed air supply.

[0179] In embodiments of the invention, the at least one evaluation unit is designed to detect wear on at least one loading and / or unloading device of at least one machine. For this purpose, in embodiments of the invention, the evaluation unit is designed to record media consumption that is directly or indirectly influenced by the state of the loading and / or unloading device and / or to evaluate machine messages relating to the loading and / or unloading device.

[0180] For example, there may be mechanical problems (e.g. with the shock absorber) on the loading and / or unloading device that result in the loading and / or unloading device not moving into the correct position.

[0181] In embodiments of the invention, the at least one evaluation unit for detecting wear is designed on at least one loading and / or unloading device of at least one machine.

[0182] In embodiments of the invention, the evaluation unit is designed to detect an oil leak on at least one machine. An oil leak can occur, for example, at connection points or a crack / hole in the oil line.

[0183] In embodiments of the invention, the at least one evaluation unit is designed to detect an oil leak on at least one machine by evaluating machine data of the hydraulic unit (e.g. oil level, energy consumption).

[0184] A machine according to the invention comprises at least one device according to the invention for acquiring measurement data from a machine. A tire curing press according to the invention comprises at least one device according to the invention for acquiring measurement data from a machine.

[0185] A method according to the invention for recording measurement data of a machine comprises at least the following steps:

[0186] Recording of at least one media consumption of at least one monitored machine,

[0187] - Automatic comparison of at least one recorded media consumption with target values,

[0188] - Automatic detection of consumption deviations exceeding defined tolerances,

[0189] Carrying out automated condition monitoring of at least one monitored machine based on detected consumption deviations.

[0190] In preferred embodiments of the invention, a cause list comprising possible causes for the detected deviation is then automatically loaded based on the at least one detected consumption deviation.

[0191] In embodiments of the invention, the retrieved cause list is then automatically output.

[0192] In embodiments of the invention, an automatic check of the possible causes of the detected consumption deviation in the cause list is carried out using at least one criterion for the clear identification of the at least one cause or for the limitation of the cause list.

[0193] In embodiments of the invention, the identified cause(s) or the narrowed down list of causes is then automatically output.

[0194] In embodiments of the invention, suggested actions and / or instructions for action to remedy the at least one identified cause are then automatically retrieved.

[0195] In embodiments of the invention, suggested actions are then automatically output and / or defined instructions for resolving the at least one cause are automatically implemented. In embodiments of the invention, data from at least one additional data source is automatically loaded in parallel with the monitoring of media consumption or after the detection of a consumption deviation and used to automatically and uniquely identify the at least one cause or to narrow down the list of causes based on predefined criteria.

[0196] In embodiments of the method according to the invention, this is designed as a method for recording measurement data of at least one tire curing press.

[0197] In preferred embodiments of the method according to the invention, at least one device according to the invention for detecting measurement data of a machine, a machine according to the invention and / or a tire curing press according to the invention is used.

[0198] In embodiments of the invention in which a digital maintenance tool for machines (e.g. for tire curing presses) is realized, the following method steps and / or features are used in the corresponding methods or devices completely or in executable combinations.

[0199] A method according to the invention for digital condition monitoring for the media consumption of a machine (e.g. a tire curing press) is described below in an embodiment according to the invention using the example of a tire curing press:

[0200] Monitoring the media consumption of a tire curing press for the production of a tire from start to finish provides information about whether the machine in question meets production requirements and design specifications. Monitoring media consumption over time based on individual sections or even individual movements provides detailed information about the condition of a tire curing press: early detection of potential machine errors, localization of problem areas and causes for error analysis, and information for preventive maintenance. Whenever the target and actual values ​​of media consumption for a section of the production cycle or an individual machine movement within the production cycle deviate beyond a specific tolerance range, this is an indicator of a certain number of possible errors and error causes.

[0201] In embodiments of the invention, the determined indicators are displayed using digital devices (e.g., smartphones, smartwatches, tablets, notebooks, PCs, digital display boards). This media consumption monitoring based on individual movements and the resulting support for error analysis and troubleshooting are at the heart of this embodiment of the invention.

[0202] This detailed media consumption monitoring is supplemented in embodiments of the invention by

[0203] The monitoring of cycle and / or sub-cycle times, a link with the collection and analysis of alarm and fault messages from the machine, the sensory monitoring of individual components, the data-based comparison of several tire curing presses with each other (“benchmarking”, creation of data-based “experience collections” / “knowledge pools” / “case databases”),

[0204] - Machine learning (ML) / artificial intelligence (AI) algorithms to predict the future behavior of the machine, 3D visualization techniques in the sense of augmented reality or virtual reality.

[0205] In embodiments of the invention, a control loop is additionally constructed using data technology and actuators, so that the previously described diagnostics / analysis is supplemented by “self-healing”, self-regulating measures.

[0206] In embodiments of the invention, media consumption of a machine (e.g. tire curing press) is monitored.

[0207] In embodiments of the invention, the last (approximately 4-5; flexibly adjustable if necessary) production cycles of a tire curing press or a group of tire curing presses (trench / entire heating chamber) are displayed as an overview during operation, and the time-dependent media consumption is compared to the specifications of the produced tire. If the actual media consumption is higher than the respective target value, the deviation, along with preferably instructions for monitoring and optimally adjusting relevant components or individual functions, are output as a message. Precise threshold values ​​and tolerance ranges are predefined.

[0208] The reporting function can be activated or deactivated in embodiments of the invention. If necessary, the operating data for the relevant assemblies or individual functions can be displayed in detail. If the total consumption of a consumable medium is not within the target, embodiments of the invention provide instructions for monitoring subsystems (e.g., supply pressure for hydraulics or pneumatics) and / or instructions for monitoring assemblies or individual functions that are not within the target or are in a faulty state and have a relevant influence on the respective medium consumption.

[0209] Depending on the machine equipment and relevant function, the performance / setting in embodiments of the invention is checked manually or automatically by sensors and adjusted manually or automatically by actuators.

[0210] For troubleshooting by the machine operator's maintenance technicians, in embodiments of the invention, suggestions for measures for problem analysis and resolution are automatically assigned in advance to the information on deviating media consumption using the know-how of machine experts and, if necessary, made accessible via a condition monitoring solution.

[0211] In embodiments of the invention, this is coupled with a short technical guide (possibly also with a link to an online training course) and is supported by component-specific data from the condition monitoring.

[0212] If a technician is unable to achieve an improvement in media consumption based on the information provided, further analysis by machine experts is required. The implementation of the information is digitally documented in embodiments of the invention.

[0213] In embodiments of the invention, the operating data of all assemblies or individual functions are stored long-term for statistical evaluations and are accessible to machine experts.

[0214] Through consumption monitoring and the associated target / actual comparison of media consumption, key figures for the productivity and / or availability of the machines are derived in embodiments of the invention.

[0215] For each individual movement, in embodiments of the invention, average values ​​of media consumption for past cycles and forecasts for future cycles are created either using statistical methods or with the aid of machine learning algorithms. The determined media consumption is displayed in tabular form in embodiments of the invention (e.g., as total consumption and media consumption per section), in detailed tabular form in embodiments of the invention (e.g., all individual movements of a phase), or in a graphical representation, for example, as a diagram (e.g., as total consumption and media consumption of individual phases).

[0216] In embodiments of the invention, key figures for productivity and availability are derived in conjunction with the collection and analysis of alarm and fault messages from the machine.

[0217] The combination of consumption monitoring and collection and analysis of alarm and fault messages realized in embodiments of the invention offers considerable advantages.

[0218] If a machine (e.g. a heating press) is not equipped with the sensors necessary for condition monitoring, in embodiments of the invention a derivation is made indirectly, from the operating behavior (actual values) and its development (trends).

[0219] In embodiments of the invention, all alarm and fault messages are stored long-term for statistical evaluation and are accessible to machine experts.

[0220] In embodiments of the invention, the processing of the messages is digitally documented, ideally according to a predefined scheme, in order to be able to create long-term analyses / correlations. The goal is to be able to conduct analyses of the machine's operating behavior based on the most detailed recording of the alarm / error message (fault analytics) and the corrective measures taken (maintenance / action log file) and a statistical evaluation. Over time, in embodiments of the invention, condition monitoring is realized through the interaction of status parameters (explicit information via sensors) and the operating behavior in certain situations using statistical methods / predictions.

[0221] In embodiments of the invention, current alarm and fault messages for a machine are displayed in an overview including symbolic criticality, message designation and time stamp.

[0222] In embodiments of the invention, details of an individual alarm and fault message for a machine are displayed, including a name, description, solution instructions, references to the same message on other machines with a time stamp, and a link to the product produced under fault conditions (product ID).

[0223] In embodiments of the invention, a message overview for several machines (e.g. tire curing presses) is output in an overview with a symbol for criticality, designation, machine location (“trench”), machine number and / or time stamp.

[0224] In embodiments of the invention, individual components of the at least one monitored machine are monitored by sensors.

[0225] If the sensor technology used reports a status value outside the tolerance range defined for the respective component, an alarm or fault message is generated in the machine in embodiments of the invention. This is then incorporated into the inventive solution.

[0226] Conversely, the use of sensory values ​​in embodiments of the invention serves to localize and verify the causes of consumption deviations as well as alarm and fault messages.

[0227] In embodiments of the invention, conclusions are drawn about possible design improvements and / or process improvements from the (local or global) comparison of alarm and fault messages from machines (e.g. tire curing presses).

[0228] In embodiments of the invention, machine learning (ML) / artificial intelligence (AI) algorithms are used to predict the future behavior of the machine.

[0229] In embodiments of the invention, average values ​​of media consumption for past cycles and forecasts for future cycles are created for each individual movement, either using statistical methods or machine learning algorithms. Various statistical methods and machine learning algorithms are possible for this purpose, and they can also be combined with each other.

[0230] The methods differ primarily in the number of input parameters, comparison / training data, and result parameters they can and must handle. Input parameters include, for example, recipe parameters, machine parameters, cycle times, alarm and fault messages, and / or sensor data.

[0231] To verify the validity of statistical methods and to "train" ML algorithms, numerous data sets are required for the input parameters. In embodiments of the invention, the results of the method and procedure are compared with the closest actual result. Through this repeated comparison, the appropriate statistical method is determined or the ML model is trained in embodiments of the invention.

[0232] Result parameters include, for example, future cycle times, alarm and fault messages, media consumption and / or machine states (sensor data to be measured).

[0233] The quality of the predictions depends on the training volume with sample data. The quality of the prediction naturally decreases the further into the future one looks.

[0234] In embodiments of the invention, 3D visualization techniques in the sense of augmented reality or virtual reality are used.

[0235] Using 3D visualization techniques in the sense of augmented reality or virtual reality, the invention enables visual navigation around and "through" the machine in corresponding embodiments, including zooming in and out for detailed or overview views. Furthermore, machine movements can be dynamically displayed and thus simulated using the 3D visualization techniques. This supports the understanding of clues provided by data analysis, as well as the localization of relevant machine locations and the identification of required spare parts.

[0236] For representation using 3D visualization techniques, in embodiments of the invention, constructive machine data (CAD data) are linked with the data that is collected or viewed (condition monitoring: cycle times, alarm and fault messages, media consumption and sensor data).

[0237] In embodiments of the invention, a control loop for "self-healing" machines is implemented. In embodiments of the invention, a control loop is additionally constructed using data technology and actuators, so that the previously described diagnostics / analysis is supplemented by "self-healing," self-regulating measures. Compared to conventional control loops, the invention is characterized in this regard by the combination of different data sources (media consumption, cycle times, sensor data, alarm and fault messages), by the use of statistical procedures and ML methods, and / or by local, regional, or global benchmarking via the centrally established data pool.

[0238] In various embodiments of the invention, the methods of cycle time monitoring, sensory monitoring, evaluation of machine messages and monitoring of media consumption are implemented with regard to the device according to the invention for recording measurement data of a machine, the method according to the invention for recording measurement data of a machine and a tire curing press according to the invention, each alone or in the various executable combinations.
