Description

Technical Field

[0001] The present invention relates to a method and an apparatus for obtaining measurement data from a machine.

Background Art

[0002] Furthermore, the present invention relates to a tire vulcanizing press (tire heating press) including at least one apparatus for obtaining measurement data of a machine.

[0003] In an embodiment, the present invention includes a digital application for a machine, particularly for a tire vulcanizing press.

[0004] Known tire presses already have a digital control system that can be used to control individual processing steps that vary depending on the mechanical device. Furthermore, many known tire vulcanizing presses also have an evaluation unit that can detect a certain function or failure of the tire vulcanizing press and generate corresponding mechanical messages.

[0005] These mechanical messages must be read and interpreted primarily by the user, operator, or maintenance manager for the known tire vulcanizing press.

[0006] For a manufacturing machine including a tire vulcanizing press, it is generally important to achieve the shortest possible process execution time in order to enable a high throughput.

[0007] The process execution time is specified for a specific machine configuration and is maintained within a certain tolerance when a new machine or a machine without wear and defects is ordered according to its specifications.

[0008] However, during the operation of the machine, wear and fatigue may occur in assemblies or components that are susceptible to wear, resulting in defects that have an adverse effect on the achievable process execution time.

[0009] Furthermore, generally, for the manufacture of machines including tire vulcanizing presses, it is important to achieve the lowest possible media consumption and enable the efficient use of media.

[0010] The media consumption in the form of, for example, (electrical) energy, compressed air, oil or hydraulic oil, nitrogen, steam or warm water required for the process cycle is specified for specific machines and process specifications and is maintained within a certain tolerance when new machines or machines without wear and defects are ordered according to those specifications.

[0011] However, during the operation of the machine, wear can occur on assemblies or components that are prone to wear, and in some cases, defects can occur that have an adverse effect on the achievable process execution time. Summary of the Invention Problems to be Solved by the Invention

[0012] Therefore, an object of the present invention is to create an apparatus for obtaining measurement data from a machine and a tire vulcanizing press that solves at least some of the aforementioned problems. Means for Solving the Problems

[0013] According to the present invention, this object is achieved by an apparatus for obtaining measurement data of a tire vulcanizing press according to claim 1 and a tire vulcanizing press according to claim 13.

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

[0015] According to the present invention, this object is achieved by a method for obtaining measurement data of a tire vulcanizing press according to claim 14.

[0016] Advantageous aspects of the present invention are claimed in the dependent claims.

[0017] The following features of the disclosure of an apparatus for obtaining measurement data from a machine, a tire vulcanizing press, and a method for obtaining measurement data from a machine are part of the invention in all possible combinations.

[0018] In an embodiment of the invention, a digital solution for condition monitoring of a machine, in particular for condition monitoring of, for example, a tire vulcanizing press for rubber, a tire manufacturing machine, a mixer, or a food and / or edible oil manufacturing machine, is realized.

[0019] An apparatus for obtaining measurement data of a machine according to the invention is designed to monitor at least one machine and includes at least one acquisition device for ascertaining at least one machine parameter of at least one monitored machine and at least one evaluation unit.

[0020] The cycle time required to complete a process cycle can be ascertained as a machine parameter using at least one acquisition device.

[0021] In an advantageous embodiment of the invention, at least one sub-cycle time corresponding to the duration of a defined process step or a sequence of defined process steps can be ascertained using at least one acquisition device.

[0022] Preferably, the cycle time required to execute a process cycle and at least one sub-cycle time can be ascertained using at least one acquisition device.

[0023] In a preferred embodiment of the invention, the process cycle is divided into a plurality of sub-cycles, and each sub-cycle corresponds to a defined machine movement or a series of machine movements.

[0024] In a particularly advantageous embodiment of the invention, the duration of each of the defined sub-cycles can be ascertained using at least one acquisition device.

[0025] In order to determine the cycle and / or sub-cycle times, at least one determining device is designed to call (read) data from the machine control device and / or to monitor each machine using sensors.

[0026] The machine control device of at least one monitored machine determines, for example by a control command, the start time of a cycle or sub-cycle and recognizes, based on measured values, the end time of a cycle or sub-cycle in the form of actuation of a switch / button when, for example, a further control command is issued to start the next process step or a certain position is reached.

[0027] In a corresponding embodiment of reading data from the machine control device, at least one determining device is designed to determine the first cycle time or sub-cycle time, for example, by measuring the time between a first control command starting a first cycle or sub-cycle and a second control command starting the next second cycle or sub-cycle, or by measuring a detection event indicating the end of the first cycle or sub-cycle.

[0028] In addition, a certain machine message may correspond to the start or end of a cycle or sub-cycle, whereby the detection of the corresponding machine message using at least one determining device may define the start or stop of a cycle or sub-cycle.

[0029] Furthermore, in embodiments of the present invention, the start and end of a cycle or sub-cycle can be detected by monitoring based on sensors of at least one monitored machine. For example, the start and end of a certain process step can be determined using imaging monitoring of at least one machine, especially when movement is caused.

[0030] In various embodiments of the present invention, all of the above-described methods for determining the cycle time and / or sub-cycle time are combined with each other in all possible options.

[0031] At least one evaluation unit of the device for obtaining measurement data of a machine according to the present invention is designed to monitor the state of at least one machine to be monitored based on the cycle time and / or sub-cycle time grasped using at least one grasping device.

[0032] In a preferred embodiment of the present invention, the condition monitoring within the scope of the present invention is specific condition monitoring of at least one machine to be monitored as a whole and at the component level and / or function level. Particularly preferably, the condition monitoring is realized at the component level.

[0033] For condition monitoring, at least one evaluation unit is preferably designed to read out stored set values (target values), tolerance values and / or limit values of at least one cycle time, preferably further of all defined sub-cycles of the cycle time.

[0034] For example, the evaluation unit is designed to read out set values from a local storage device as part of the device for obtaining measurement data and / or from an external data storage device as part of a machine-common database at the manufacturing site or in the cloud. Preferably, the associated tolerance ranges or limit values are derived for at least one cycle and / or sub-cycle time. In principle, according to the present invention, it is also possible that only the tolerance ranges and / or limit values of all cycle times / sub-cycle times are derivable.

[0035] In addition, at least one evaluation unit is designed to compare the grasped actual cycle time and / or sub-cycle time with the set value and / or tolerance range or limit value for the set value.

[0036] If at least one of the grasped times does not fall within the tolerance range of the set value defined for the entire process and / or for each process step or is below the respective limit value, at least one evaluation unit is designed to detect a time deviation.

[0037] In an embodiment of the present invention, when a time shift is detected, at least one evaluation unit is designed to generate a shift signal that signals at least one shift / deviation of the grasped time.

[0038] In an embodiment of the present invention, at least one evaluation unit is designed to output at least one shift signal when a time shift is detected.

[0039] Preferably, the shift signals are individually distinguishable according to their respective cycles or sub - cycles, such that the shift signals can be used to determine which cycle / sub - cycle is shifted from a set value or a plurality of set values.

[0040] In an embodiment of the present invention, at least one evaluation unit can be used to generate a shift message that identifies at least the shifted (deviation - indicating) cycle and / or sub - cycle depending on the individual shift / deviation between the target time and the actual time.

[0041] In an embodiment of the present invention, the evaluation unit is designed to automatically detect at least one cause underlying the time shift or at least to automatically define possible causes / conceivable causes.

[0042] By the assignment of sub - cycles to specific process steps or machine movements, it becomes possible to narrow down the possible causes to those that affect the duration of each sub - cycle based on the identification of the shifted sub - cycles.

[0043] In an advantageous embodiment of the present invention, at least one evaluation unit can be used to read out a list of causes assigned to individual cycles or sub - cycles, including various suitable causes / possible causes for each time shift.

[0044] Causes of the deviation in cycle time or sub - cycle time can include wear, defects, incorrect settings, material defects and / or manufacturing defects.

[0045] Preferably, at least one criterion is assigned to each cause listed in the cause list, and by checking the presence or absence of at least one criterion, it is possible to determine whether each cause applies or may apply.

[0046] In an embodiment of the present invention, at least one evaluation unit having a deviation signal and / or a deviation message is designed to output each cause list and / or criterion list.

[0047] By collecting additional data, it is sometimes possible to clearly identify the cause from the cause list or at least further narrow down the cause list.

[0048] Monitoring the cycle time of a machine, as compared to the primary collection and analysis of warning messages and failure messages from the machine, has the advantage that it can respond to a gradually progressing deterioration that would not have been noticed earlier in the machine process ("process drift") at a very early stage. Further, monitoring of the cycle time, especially the sub - cycle time, can support the search for the trigger of an error message when this is not clear.

[0049] In an advantageous embodiment of the present invention, at least one evaluation unit is designed to read out additional data in the case of a detected time deviation, and based on its evaluation, the cause can be automatically identified or at least further narrowed down in relation to the detected time deviation.

[0050] In an embodiment of the present invention, at least one evaluation unit is designed to correlate the detected (sub) cycle deviation with additional read - out data.

[0051] In an embodiment of the present invention, the readable additional data includes sensor data and / or machine messages and / or media consumption related to at least one monitored machine and / or the corresponding machine, respectively.

[0052] In a corresponding embodiment of the present invention, by using at least one evaluation unit to evaluate sensor data, machine messages and / or media consumption that can be provided by measurement values related to the machine, it is possible to check the criteria for the existence of specific causes for one or more time offsets.

[0053] In an embodiment of the present invention, at least one evaluation unit is designed to automatically generate a proposal for removing the cause based on the determined cause or the possible cause for at least one detected deviation, and / or to execute automatic cause removal, and / or to output a proposal or instruction for further cause determination.

[0054] The monitoring by at least one sensor, for example, a sensor of a tire vulcanizing press, implemented in an embodiment of the present invention is realized by at least one sensor arranged to obtain data related to at least one monitored machine.

[0055] The at least one sensor may be an integral part of at least one machine to be monitored, or a sensor arranged within, on, or in the area of at least one machine to be monitored as part of a device for obtaining measurement data.

[0056] In various embodiments of the present invention, at least one of the following sensors, for example, is arranged for corresponding use: a pressure sensor and / or a flow sensor (e.g., for steam, air, nitrogen, or hydraulic oil) and / or a sensor for measuring voltage, current, or power and / or a vibration sensor and / or a temperature sensor and / or a particle monitor and / or a humidity sensor and / or a viscosity sensor and / or an image sensor and / or a speed sensor and / or an acceleration sensor and / or a force sensor and / or a sensor for determining valve state.

[0057] In an embodiment of the present invention, the evaluation unit is designed to read and evaluate sensor data (measurement values) of at least one sensor arranged to record data related to at least one machine to be monitored.

[0058] In an embodiment of the present invention, at least one evaluation unit is designed to read and evaluate sensor data (measurement values) when a time shift occurs. Data reading based on this event ensures a smaller amount of data to be processed compared to continuous reading.

[0059] In other embodiments of the present invention, at least one evaluation unit is designed to continuously read sensor data. Continuous data reading provides a wide range of databases that can be used, for example, with artificial intelligence (AI) and / or machine learning (ML) to predict the state of a machine.

[0060] In an embodiment of the present invention, it is also possible to combine the reading of sensor data when a time shift occurs for a first group of sensor data that includes at least the sensor data obtained by the sensor with the continuous reading of sensor data of a second group of sensor data.

[0061] In an advantageous embodiment of the invention, the setpoint is readable for sensor data that can be determined in each configuration using at least one evaluation unit, and the determined sensor data is comparable with the setpoint. If the measured value is outside any defined tolerance around the setpoint, the measured value deviation can be determined using at least one evaluation unit.

[0062] The deviation of the measured value of one or more sensors from the setpoint is an indicator of a specific cause, error or defect.

[0063] In an advantageous embodiment of the invention, a cause list is readable using at least one evaluation unit for various measured value deviations or combinations of measured value deviations, whereby the cause, error or defect can be automatically and unambiguously identified, or the cause list is automatically further limited using at least one evaluation unit.

[0091] In an embodiment of the present invention, at least one evaluation unit is designed to read and evaluate machine messages from at least one machine to be monitored.

[0092] Machine messages are messages that are usually automatically generated by the control device of each machine depending on the status. In particular, warning messages and / or fault messages are such machine messages, but these may further include, for example, general status messages.

[0093] Depending on the monitored machine and the machine software / PLC (programmable logic controller) software, there are, for example, 500 to 1500 different machine messages. These are currently not standardized in terms of their types and error codes and depend on individual customer specifications and the respective machine control devices. In a preferred embodiment of the present invention, since these machine messages are very accurate and clear, the user can directly determine the cause / source of the error from them and can also receive instructions for actions.

[0094] In an embodiment of the present invention, at least one evaluation unit is designed to read out and evaluate machine messages from at least one monitored machine when a time deviation occurs.

[0104] In an advantageous embodiment of the present invention, a set value is readable for at least one medium consumption that is readable in each configuration using at least one evaluation unit, and the recorded medium consumption is comparable to the set value. If the consumption value is outside the range of any defined tolerance value near the set value, a consumption deviation can be determined using at least one evaluation unit.

[0105] At least one deviation in media consumption from a set value can, in some cases, be an indicator of a specific cause, malfunction, or defect.

[0106] In an advantageous embodiment of the invention, a cause list is readable for various consumption deviations or combinations of consumption deviations using at least one evaluation unit, so that causes, malfunctions, or defects can be clearly and automatically identified, or the cause list can be automatically further limited at least using at least one evaluation unit.

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

[0108] In an embodiment of the invention, the additional data source is, for example, another machine having the same or almost the same structure, preferably of the same machine type, a process or device arranged along the value chain in front of or behind at least one monitored machine, for example a central storage device and / or evaluation unit having greater resources for performing extensive data evaluation or having access to large amounts of data, the design data of at least one monitored machine and / or the CAD model of at least one monitored machine.

[0109] The central storage device and / or evaluation unit can be realized, for example, on a local server, in particular at the installation site of at least one monitored machine (e.g., at the manufacturing site), and / or on a cloud server.

[0110] The use of the central storage device and / or evaluation unit saves additional processing power for data processing on each individual machine and, in an embodiment of the invention, enables the display of the results of data evaluation via mobile data technology regardless of location, as well as local, regional, or worldwide standards and benchmarks for various monitored machines.

[0111] In an embodiment of the present invention, at least one evaluation unit is designed to perform a comparison based on criteria / benchmarks - i.e., data of several monitored machines (e.g., tire vulcanizing presses) locally at one plant, regionally for several plants, and globally across a number of / all plants.

[0112] This provides the following advantages for the operator or manufacturer of the monitored machine:

[0113] From a (local or global) comparison with the same machine, conclusions about the state of the machine can be drawn, taking into account the respective product configuration if necessary. In an embodiment of the present invention, this is done automatically.

[0114] From a (local or global) comparison with machines having other designs, conclusions about possible design improvements and / or process improvements can be drawn, taking into account the respective product configuration in some cases. In an embodiment of the present invention, this is done automatically.

[0115] Conclusions about the factory's capabilities can be drawn from the productivity and availability and the derived values for their local, regional, or global comparison. These are made available to different user groups according to the identified access authorizations and in an anonymized form. In an embodiment of the present invention, this is done automatically.

[0116] In an embodiment of the present invention, the integration of upstream processes (e.g., mixer, extrusion, and tire building in tire manufacturing) and downstream process steps (e.g., quality control) in product manufacturing can be used to diagnose the machine state and / or the product quality of individual products (e.g., tires) using at least one evaluation unit.

[0117] In an embodiment of the present invention, for example, the tire structure is identified by information about the dimensions (e.g., diameter and width), weight, composition of the rubber compound of the green tire, and / or the (layer) structure of the green tire, and can be read from a data source using at least one evaluation unit. This means, for example, that a specific weight of the green tire can be considered as a factor affecting the duration of a certain movement with respect to a sub-cycle.

[0118] In an exemplary embodiment of the present invention, in order to provide a basis for the effect of the process parameters of the tire vulcanizing press on product quality, feedback to the tire vulcanizing press monitored from quality control is established.

[0119] In an embodiment of the present invention, product-related data is available taking into account the entire value chain by integrating other process steps of the value chain.

[0120] For example, in a corresponding embodiment of the present invention, the energy requirements and / or material requirements for tire manufacturing can be identified. The data basis can also be used for maintenance management and can optimize machine operation and / or troubleshooting and / or further product development of the manufactured product.

[0121] Furthermore, in an embodiment of the present invention, methods of machine learning and / or artificial intelligence are applied to process-related and machine-related data of the entire value chain, and for example, it is possible to determine a prediction of the product quality of a tire based on process data. Therefore, in a corresponding embodiment of the present invention, the need for quality assurance measures at the end of the value chain can be reduced.

[0122] In an embodiment of the present invention, the evaluation unit and the data evaluated over time by the evaluation unit are used to perform state monitoring using the interaction of state parameters using statistical methods / predictions and state prediction in the operating behavior in a certain situation.

[0123] In an embodiment of the present invention, at least one evaluation unit is designed to apply methods of artificial intelligence (AI) and / or machine learning (ML) to data that can be read. By evaluating a large amount of data, it is possible to determine the relationship between changes and / or trends in individual data and the occurrence of certain causes of defects, whereby in an embodiment of the present invention, the future state of at least one monitored machine can be predicted.

[0124] In an embodiment of the present invention, this enables the early transmission of warning messages regarding imminent defects and / or required maintenance.

[0125] In an embodiment of the present invention, the state of at least one monitored machine, for example a tire vulcanizing press, can be displayed in a digital application (app).

[0126] In an embodiment of the present invention, the determined indicators can be output by a digital end device as an optical display. A digital end device in this sense is, for example, a smartphone, smartwatch, tablet, notebook, PC or digital display panel.

[0127] In an embodiment of the present invention, current warning messages and / or fault messages for the machine, including importance / risk using symbols, message designation (message name) and timestamp, can be displayed at a glance.

[0128] In an embodiment of the present invention, details of individual warning messages and / or fault messages related to the machine can be displayed by name, description, solution display, reference to the same message on other machines with timestamp and / or a link to products manufactured under fault conditions (e.g., tire ID).

[0129] In an embodiment of the present invention, a message overview of several monitored machines (e.g., tire vulcanizing presses) can be output at a glance using symbols for risk, designation, machine location ("trench"), machine number and / or timestamp.

[0130] In an embodiment of the present invention, the comparison and simultaneous display of failure messages from several monitored machines (e.g., tire vulcanizing presses) in a factory provide maintenance management with a maintenance control station, whereby the currently required maintenance measures for all monitored machines (e.g., tire vulcanizing presses) can be immediately understood. This data basis can be used to derive priorities for maintenance and service and to identify related failures of several machines against the background of a common infrastructure (e.g., group hydraulics, heating medium, etc.).

[0131] In a preferred embodiment of the present invention, the last, for example, about 10 cycle times of a monitored machine or a group of monitored machines (i.e., a heating press or a group of heating presses, e.g., an entire trench / heating chamber), which can be flexibly adjusted as required, can be displayed as an overview during operation and can be set with respect to the specifications of the tires to be manufactured. If the actual cycle time is more than the target cycle time, a deviation and, optionally, an option instruction for checking and / or optimally setting the related assembly or individual function can be output as a message. Exact thresholds and tolerances for the monitored machines can be defined for each machine configuration. The message function can be (de)activated. In an embodiment of the present invention, the operating data for the related assembly or individual function can be displayed in detail.

[0132] In an advantageous embodiment of the present invention, at least one improvement measure for at least one monitored machine can be automatically proposed based on evaluation data by at least one evaluation unit.

[0133] In an embodiment of the present invention, by this solution, for example, the machine performance can be improved by increasing productivity, for example, by stably maintaining a low cycle time or cycle times of a tire vulcanizing press.

[0134] In an embodiment of the present invention, at least one evaluation unit can be used to generate an early warning based on evaluation data, which can avoid unplanned downtime, assist repair and maintenance measures, and / or increase machine availability by reducing the consumption of spare parts.

[0135] In an embodiment of the present invention, a digital solution can display the energy consumption of at least one machine under monitoring, such as a tire vulcanizing press, during manufacturing, thus enabling the user or operator of the machine to access measures for improving energy consumption / CO2 footprint.

[0136] In an embodiment, the present invention provides the following advantages or has the following features individually or in combination.

[0137] Optimization of machine performance, monitoring and stabilization of the cycle time of low-level machines, such as tire vulcanizing presses, transmission of early warning messages when the cycle time exceeds a certain threshold, indication of the causes of continuous and gradual increases within the cycle time, such as undetected leaks, wear or incorrect settings, reduction of the actual cycle time of tire vulcanizing presses by an average of 10 to 20 seconds per cycle, and increase in productivity of tire vulcanizing presses of about 600 to 1800 tires per year (+1 to 3%).

[0138] In an embodiment of the present invention, improved machine availability is made possible. This is achieved particularly by the following measures individually or in practical combinations: - Reduction of unplanned downtime by early warning of events such as leaks, wear and tears, - Avoidance of unnecessary cooling and preheating by reducing unplanned downtime, - Shortening of repair time by identifying the causes of defects and thereby assisting in targeted countermeasures, - Reduction of planned maintenance by focusing on measures for problems that require repair, - Optimization of spare part consumption by replacement based on the condition of spare parts, -Lower operating costs by reducing conservative management time and avoiding unnecessary expenses, -Reduce energy costs and unnecessary energy consumption through real-time monitoring, -Overall cost reduction of 1-3% per vulcanized tire.

[0139] In the embodiments of the present invention, reasonable vulcanization of tires is realized.

[0140] In the embodiments of the present invention, so-called "smart vulcanization" includes the arrangement with the tire vulcanizing press in the vulcanization area and data exchange with a database necessary for recording production data and process data. This system enables simultaneous production monitoring, traceability, manufacturing method management, and analysis of the tire vulcanizing press.

[0141] In the embodiments of the present invention, a control loop that interferes with the machine control system depending on the detected time shift or the identified cause of the time shift (for example, automatically providing digital parameters of the machine PLC, changing the configuration), or a control loop that uses a mechanical actuator to accurately interfere with the system to be controlled is implemented, thereby enabling a "self-recovering" tire vulcanizing press.

[0142] The applicable fields include production monitoring (for example, production plan vs. actual OEE, TCO), process monitoring (for example, vulcanization data acquisition, manufacturing method management, quality assurance), machine monitoring (for example, condition monitoring, predictive maintenance, alarm diagnosis method, machine service), and energy monitoring (for example, electricity, compressed air, oil, vulcanizing agent).

[0143] In the embodiments of the present invention, the applied technologies / methods include, for example, sensor technology, actuator technology, PLC programming and PLC control, formation of an IT-network for machines (such as tire vulcanizing presses), edge / fog, edge / fog computing, IIoT gateway, Internet connection / protocol, cloud technology, data analysis, mobile applications, machine learning algorithms / artificial intelligence, virtual reality and / or augmented reality.

[0144] According to the digital solution for the condition monitoring of a machine (for example, a tire vulcanizing press) according to the present invention, in an embodiment of the present invention, it is possible to display the condition of the machine on a digital application and automatically propose improvement measures to operators and maintenance personnel, and also enable technically self-healing and automatic control measures of the machine during manufacturing.

[0145] The application fields include production monitoring (for example, maintaining the cycle time of a tire vulcanizing press stably and low to increase productivity by outputting the deviation between a predetermined set value and the measured actual value in the cycle time of a (partial) phase of the tire vulcanization process), process monitoring (for example, using machine warning messages and machine parameters to display quality defects in the tire vulcanization process, thereby providing assistance to prevent a process deviation that would otherwise lead to a continuous increase in cycle time in the tire vulcanization process that was not noticed before), machine monitoring / machine control (for example, by correlating cycle time deviation with machine parameters and / or fault messages). In this way, an automatic display of the cause of the failure can be derived, and an automatic proposal for troubleshooting can be made.

[0146] In an embodiment of the present invention, a digital maintenance tool for a machine (for example, for a tire vulcanizing press) is realized.

[0147] In an embodiment of the present invention, a method and an apparatus for the efficient and effective maintenance of a machine (for example, a tire vulcanizing press) are realized for this purpose.

[0148] In an embodiment of the present invention, the method and the apparatus are based on the principles of digital condition monitoring and / or artificial intelligence.

[0149] In an embodiment of the present invention, at least one evaluation unit is designed to detect wear or defects in at least one assembly such as a hydraulic unit, a pneumatic unit, a loading device and / or an unloading device, a closing unit or a security scanner.

[0150] In a preferred embodiment of the present invention, at least one evaluation unit is designed to detect wear or defects in at least one component itself or as part of an assembly such as a shock absorber, a hydraulic cylinder, a motor, a line (leak / obstruction) or a sensor.

[0151] In an embodiment of the present invention, at least one evaluation unit is designed to detect wear or defects in at least one hydraulic unit. For this purpose, in an embodiment of the present invention, the evaluation unit is designed to grasp the cycle time or sub-cycle time that is directly or indirectly affected by the state of the hydraulic unit, and / or to detect the hydraulic pressure using at least one pressure sensor, and / or to evaluate mechanical messages and / or control parameters (configurations) related to the hydraulic unit.

[0152] In an embodiment of the present invention, 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 has a defect or is worn, a different pressure, usually a reduced pressure, is provided instead of the set pressure. This decelerates the movement realized by the hydraulic pressure of the machine, thereby making the corresponding cycle time and / or sub-cycle time longer.

[0153] In an embodiment of the present invention, using at least one evaluation unit, based on the detected deviation of the cycle time or sub-cycle time having a possible cause in the hydraulic device, a cause list including, for example, wear of the hydraulic unit due to a cause, a leak in the hydraulic device, defective operation of the hydraulic unit, defective adjustment of the hydraulic device and wear of the hydraulic cylinder, is readable.

[0154] In an advantageous embodiment of the invention, at least one evaluation unit is used to automatically narrow down at least one cause underlying at least one detected deviation, such that criteria for the individual possible causes are readable, preferably automatically checkable.

[0155] For example, in an embodiment of the invention, one or more of the following criteria are readable, preferably checkable: the pressure in the pressure line of the hydraulic unit, electrical parameters (current, voltage, power consumption) in the hydraulic unit, the temperature of the hydraulic oil, the oil quantity of the hydraulic unit, the flow rate in the hydraulic lines of the hydraulic unit (leakage detection), the vibration of the motor of the hydraulic unit, mechanical messages or temperature warnings for interruptions of the hydraulic movement, hydraulic oil, data of the upstream and / or downstream value chain.

[0156] In a corresponding embodiment of the invention, based on the gist of the criteria that are met or not met, at least one cause can be automatically and clearly determined using at least one evaluation unit, or the list of causes can be at least further reduced.

[0157] In an embodiment of the invention, at least one evaluation unit is designed to detect defects and / or wear of the closing unit of the tire vulcanization press. In an embodiment of the invention, defects / wear of the closing unit can be detected by evaluating the cycle time and / or the sub-cycle time, and / or by monitoring the energy consumption of the hydraulic unit, and / or by evaluating mechanical messages.

[0158] In an embodiment of the present invention, at least one evaluation unit is used to, based on the detected deviation of the cycle time or sub-cycle time having a cause that may be related to the closing unit, for example, the cause of insufficient lubricating oil of a slide platen or a tire-type mold segment, hydraulic leakage during segment operation, incorrect operation (configuration) of the hydraulic function for closing the press, incorrect setting of the hydraulic function for closing the press (for example, setting of a pressure safety valve), a cause list can be read out.

[0159] In an advantageous embodiment of the present invention, criteria for individual possible causes are readable using at least one evaluation unit, preferably automatically checkable, in order to automatically narrow down at least one cause underlying at least one detected deviation.

[0160] For example, in an embodiment of the present invention, one or more of the following criteria are readable, preferably checkable: the pressure in the pressure line of the hydraulic unit, the provided hydraulic closing pressure, the electrical parameters (current, voltage, power consumption) in the hydraulic unit, the temperature of the hydraulic oil, the flow rate in the hydraulic line of the hydraulic unit (leakage detection), the oil quantity of the hydraulic unit, the vibration of the motor of the hydraulic unit, the mechanical message for interruption of the closing process, the data of the upstream and / or downstream value chain.

[0161] In a corresponding embodiment of the present invention, based on the gist of the criteria that are met or not met, at least the cause can be automatically and clearly determined using at least one evaluation unit, or the cause list can be at least further reduced.

[0162] In an embodiment of the present invention, at least one evaluation unit is designed to detect defects and / or wear of at least one security scanner in at least one machine.

[0163] For example, contamination of the security scanner of a machine designed as a tire vulcanizing press machine results in irregular machine stoppages. If such a machine stoppage occurs during the vulcanization of a tire, this usually results in an over-vulcanized tire, thus producing defective products.

[0164] In an embodiment of the present invention, at least one evaluation unit is designed to detect defects and / or wear of at least one security scanner of at least one machine by evaluating machine messages.

[0165] In an embodiment of the present invention, at least one evaluation unit is designed to detect disconnection of at least one sensor of at least one machine.

[0166] For example, if the sensor cable is broken, the sensor can be disconnected.

[0167] In an embodiment of the present invention, at least one evaluation unit is designed to detect disconnection of at least one sensor of at least one machine by evaluating machine messages and / or by evaluating cycle time and / or sub-cycle time.

[0168] In an embodiment of the present invention, at least one evaluation unit is designed to detect necessary maintenance measures.

[0169] In an embodiment of the present invention, at least one evaluation unit is designed to evaluate machine messages and / or to evaluate the current process step in the process cycle.

[0170] For example, at least one evaluation unit is designed to evaluate machine messages for an enable signal, especially in the case of a tire vulcanizing press machine, and to compare the enable signal with the current process step of the process cycle.

[0171] In an embodiment of the present invention, at least one evaluation unit is designed to monitor the downtime of at least one machine. In an embodiment of the present invention, the development of downtime, especially their increase, is also an indicator of the need for maintenance measures.

[0172] In an embodiment of the present invention, at least one evaluation unit is designed to monitor sensor signals and / or messages from the safety system of at least one machine.

[0173] In an embodiment of the present invention, at least one evaluation unit is designed to evaluate light barrier signals. Light barriers are often used to protect the safety area around a machine, for example, around a tire vulcanizing press. As soon as the light barrier is activated, the machine is stopped.

[0174] The present invention enables the visualization of the corresponding activation of safety devices due to machine messages and / or cycle interruptions.

[0175] In an embodiment of the present invention, at least one evaluation unit is designed to detect defects and wear of at least one pneumatic unit. For this purpose, in an embodiment of the present invention, the evaluation unit is designed to grasp the cycle time and / or sub-cycle time that is directly or indirectly affected by the state of the pneumatic unit, and / or to detect the air pressure using at least one pressure sensor, and / or to evaluate machine messages related to the pneumatic unit.

[0176] In an embodiment of the present invention, at least one evaluation unit is designed to detect defects in the compressed air supply of the pneumatic device of at least one machine. For this purpose, in a preferred embodiment of the present invention, the evaluation unit is designed to monitor the pressure in the pneumatic device and / or in the compressed air supply.

[0177] In an embodiment of the present invention, at least one evaluation unit is designed to detect wear of at least one loading device and / or at least one unloading device of at least one machine. For this purpose, in an embodiment of the present invention, the evaluation unit is designed to determine a cycle time or a sub-cycle time that is directly or indirectly affected by the state of the loading device and / or the unloading device, and / or to evaluate machine messages related to the loading device and / or the unloading device.

[0178] For example, the loading device and / or the unloading device (for example, the buffer device) may have mechanical problems that prevent them from moving the loading device and / or the unloading device to the correct position.

[0179] In an embodiment of the present invention, at least one evaluation unit is designed to detect wear of at least one loading device and / or at least one unloading device of at least one machine.

[0180] In an embodiment of the present invention, at least one evaluation unit is designed to detect oil leakage in at least one machine. Oil leakage can occur, for example, at a connection point or at a crack / hole in an oil line.

[0181] In an embodiment of the present invention, at least one evaluation unit is designed to detect oil leakage in at least one machine by evaluating mechanical data (for example, oil quantity, energy consumption) of a hydraulic unit.

[0182] A machine according to the present invention has at least one device according to the present invention for obtaining measurement data of the machine.

[0183] A tire vulcanizing press according to the present invention has at least one device according to the present invention for obtaining measurement data of the machine.

[0184] A method for obtaining measurement data of a machine according to the present invention includes at least the following steps: - Determine at least one cycle time and / or sub-cycle time of at least one machine to be monitored, - Automatically compare the at least one cycle time and / or sub-cycle time determined with a set value, - Automatically detect a time deviation exceeding a defined tolerance value, - Based on the detected time deviation of the cycle time and / or sub-cycle time, perform automatic condition monitoring of at least one machine to be monitored.

[0185] In a preferred embodiment of the present invention, a cause list including possible causes for the detected deviation is then automatically read based on the at least one detected time deviation.

[0186] In an embodiment of the present invention, the read cause list is then automatically output.

[0187] In an embodiment of the present invention, an automatic check of the causes of the cause list suitable for the detected time deviation is performed using at least one criterion for clearly identifying at least one cause or for narrowing down the cause list.

[0188] In an embodiment of the present invention, the identified cause(s) or the narrowed-down cause list is then automatically output.

[0189] In an embodiment of the present invention, an action proposal and / or action instruction for correcting the identified at least one cause is later automatically read.

[0190] In an embodiment of the present invention, the action proposal is then automatically output, and / or a defined instruction for correcting at least one cause is automatically executed.

[0191] In an embodiment of the present invention, data is automatically read from at least one additional data source in parallel with the monitoring of the cycle time and / or sub-cycle time or after the detection of a time shift and used for the automatic clear identification of at least one cause or for the narrowing down of a cause list based on defined criteria.

[0192] In an embodiment of the method according to the present invention, it is designed as a method for obtaining measurement data of at least one tire vulcanizing press.

[0193] In a preferred embodiment of the method according to the present invention, at least one device for obtaining measurement data of a machine according to the present invention, a machine according to the present invention and / or a tire vulcanizing press according to the present invention is used.

[0194] In an embodiment of the present invention in which a digital maintenance tool for a machine (for example, for a tire vulcanizing press) is realized, the following method steps and / or features are used in a corresponding method or device as a whole or in a practical combination.

[0195] A method according to the present invention for digitally condition monitoring ( "condition monitoring") the cycle time of a machine (for example, a tire vulcanizing press) is described below in an embodiment according to the present invention using the example of a tire vulcanizing press:

[0196] Monitoring the cycle of a tire vulcanizing press from start to finish for manufacturing a tire provides information on whether the machine in question meets the manufacturing requirements and design specifications. Monitoring the cycle over time even based on individual sections or individual movements provides detailed information about the state of the tire vulcanizing press: early detection of possible machine defects, location confirmation of problem areas and the cause of problems during defect analysis as well as information about preventive maintenance. Whenever the target time and actual time of an individual machine movement or section in the manufacturing cycle deviate from a specific tolerance range, this is an indicator of a number of possible defects and defect causes.

[0197] In an embodiment of the present invention, the determined indicators are displayed by a digital end device (e.g., a smartphone, smartwatch, tablet, notebook, PC, or digital display panel).

[0198] This cycle time monitoring based on individual movements, and the derived assistance for error analysis and error correction, are the focus of this embodiment of the present invention.

[0199] In an embodiment of the present invention, this detailed cycle time monitoring is supplemented as follows. - Link to the collection and analysis of warning messages and failure messages from the machine, - Monitoring by sensors of individual components, - Comparison based on data between some tire vulcanizing presses and other machines ("benchmarking", creation of "experience collection" / "knowledge pool" / "case database"), - Machine learning (ML) / artificial intelligence (AI) to predict the future behavior of the machine, - 3D visualization technology in the sense of augmented reality or virtual reality.

[0200] In an embodiment of the present invention, a control loop is set up using data technology and actuators, and the above-described diagnosis / analysis is supplemented by "self-healing", automatic control measures.

[0201] In an embodiment of the present invention, the cycle time of a machine (e.g., a tire vulcanizing press) is monitored.

[0202] In an embodiment of the present invention, the last (about 4 - 5; optionally adjustable flexibly) cycle time of a tire vulcanizing press or a group of tire vulcanizing presses (trench / whole heating chamber) is displayed as an overview during operation and set with respect to the specifications of the tires to be manufactured. If the actual cycle time is higher than the target cycle time, a deviation, and preferably, instructions for checking and optimally setting the relevant assembly or individual functions are output as a message. Exact thresholds and tolerance ranges are predefined.

[0203] In an embodiment of the present invention, the signaling function can be (de)activated. If necessary, the operation data for the relevant assembly or individual function can be displayed in detail.

[0204] In an embodiment of the present invention, when the total cycle time is not within the target, instructions for checking the subsystem (e.g., supply pressure for hydraulics or aerodynamics), and / or instructions for checking the assembly or individual function that is not within the target / faulty and has an impact on the respective (process) part are provided.

[0205] Depending on the machinery equipment and related functions, the power / regulation in an embodiment of the present invention is manually or automatically checked by sensors and manually or automatically adjusted by actuators.

[0206] For troubleshooting by the maintenance technician of the machine operator, in an embodiment of the present invention, proposals for problem analysis and problem removal are automatically pre-assigned to the display of the cycle time deviated by the know-how of the machine expert and, if necessary, made available via a condition monitoring solution.

[0207] In an embodiment of the present invention, this is combined with a technical quick guide (and in some cases also linked to an online learning link) and supported by component-specific data from condition monitoring.

[0208] If the technician cannot improve the cycle time based on the instructions, further analysis by a machine expert is required. In an embodiment of the present invention, the processing of the instructions is digitally documented (recorded in a document).

[0209] In an embodiment of the present invention, the operation data of all assemblies or individual functions are stored for a long time and accessible to machine experts for statistical evaluation.

[0210] In an embodiment of the present invention, cycle time monitoring and associated target-actual-comparisons of travel times are used to derive key metrics for the productivity and / or usability of the machine.

[0211] In an embodiment of the present invention, the average of past cycles and the prediction of future cycles are generated for each individual movement either from statistical methods or using machine learning algorithms.

[0212] In an embodiment of the present invention, the determined cycle times are presented in tabular form (e.g., as total duration and duration per section), in detail in tabular form in an embodiment of the present invention (i.e., all individual movements of the phase) or in graphical display form, e.g., as a chart (e.g., as total cycle duration and duration of individual phases).

[0213] In an embodiment of the present invention, metrics for productivity and usability are derived together with the collection and analysis of warning messages and fault messages from the machine.

[0214] The combination of cycle time monitoring and the collection and analysis of warning messages and fault messages realized in an embodiment of the present invention offers considerable advantages.

[0215] If the machine (e.g., a heat press) is equipped with the necessary sensor technology for condition monitoring, in an embodiment of the present invention, this is directly derived from the operating behavior (measured values) and its development (trend).

[0216] In an embodiment of the present invention, all warning messages and fault messages are stored in long-term memory for statistical analysis and to be accessible to machine experts.

[0217] In an embodiment of the present invention, in order to enable long-term analysis / correlation, the processing of messages is ideally digitally documented according to a defined plan. The aim is to be able to perform an analysis of the operating behavior of the machine from the most detailed possible recording of warning messages / error messages (fault analysis), from the corrective measures taken (maintenance / action log file), and from the statistical evaluation. Over time, in an embodiment of the present invention, condition monitoring is realized in the interaction between the condition parameters [clear information via sensors] and the operating behavior in a certain situation using statistical methods / predictions.

[0218] In an embodiment of the present invention, an overview of the current warning messages and fault messages for the machine, including importance / crisis, message designation, and timestamp using symbols, is displayed.

[0219] In an embodiment of the present invention, the details of the individual warning messages and fault messages for the machine are displayed by name, description, solution instructions, reference to the same message to other machines having a timestamp, and a link to the product manufactured under the fault condition (e.g., product ID).

[0220] In an embodiment of the present invention, a message overview of several machines (e.g., tire vulcanizing presses) is output using an overview of danger, designation, machine location ("trench"), machine number, and / or timestamp.

[0221] In an embodiment of the present invention, the individual components of at least one monitored machine are monitored by sensors.

[0222] In an embodiment of the present invention, when the sensor system used reports a status value outside the respective tolerance range defined for the component in question, a warning message or a fault message is sent to the machine. This is then incorporated into the solution according to the present invention.

[0223] Conversely, the inclusion of sensor values in embodiments of the present invention functions to localize and check for the validity of causes of temporal deviation of cycle times and for the validity of causes of warning messages and fault messages.

[0224] In embodiments of the present invention, a (local or global) comparison of warning messages and fault messages from machines (e.g., tire vulcanizing presses) is used to draw conclusions about possible design improvements and / or process improvements.

[0225] In embodiments of the present invention, machine learning (ML) / artificial intelligence (AI) algorithms are used to predict the future behavior of machines.

[0226] In embodiments of the present invention, the average value of past cycles and the prediction of future cycles are generated for each individual movement either from statistical methods or using machine learning algorithms. A variety of statistical methods and machine learning algorithms can be used for this purpose, and they can be further combined together and with each other.

[0227] The procedures basically differ in terms of how many input parameters, comparison data / training data, and result parameters can or must be processed.

[0228] Input parameters are, for example: manufacturing process parameters, machine parameters, cycle times, warning messages and fault messages, and / or sensor data.

[0229] A number of data sets for input parameters are required to check the validity of statistical methods and to "teach" machine learning algorithms. In embodiments of the present invention, the results of the methods and the methods themselves are compared with the next actual results, respectively. In embodiments of the present invention, appropriate statistical methods are determined or machine learning models are trained by this repeated comparison.

[0230] The result parameters are, for example, future cycle times, warning messages and error messages, and / or the machine state (sensor data to be measured).

[0231] The quality of the prediction depends on the "training range" with exemplary data. The further into the future, the quality of the prediction naturally decreases.

[0232] In embodiments of the present invention, 3D visualization technology in the sense of augmented reality or virtual reality is used.

[0233] By using 3D visualization technology in the sense of augmented reality or virtual reality, the present invention enables visual navigation around and "through" the machine in the corresponding embodiments, including enlargements or reductions for detailed or overview drawings. Furthermore, the machine movement can be displayed dynamically and thus simulated using 3D visualization technology. This supports the tracking of information via data analysis and the localization of the associated machine positions and the identification of the spare parts required.

[0234] In embodiments of the present invention, constructive machine data (CAD data) is linked to the data (condition monitoring: cycle times, warning messages and error messages, and sensor data) collected or displayed for display using 3D visualization technology.

[0235] In embodiments of the present invention, a control loop for "self-healing" the machine is implemented.

[0236] In embodiments of the present invention, the control loop is additionally set up using data technology and actuators, whereby the above-described diagnosis / analysis is supplemented by "self-healing" automatic control measures. Compared to conventional control loops, the present invention is characterized in this regard by a combination of different data sources (cycle times, sensor data, warning messages and error messages), the use of statistical procedures and machine learning methods, and / or local, regional or worldwide standards / benchmarks via a centrally established information aggregation (data pool).

[0237] In various embodiments of the present invention, the methods of cycle time monitoring, sensor monitoring, evaluation of machine messages, and monitoring of media consumption are implemented with respect to an apparatus for obtaining measurement data of a machine according to the present invention, a method for obtaining measurement data of a machine according to the present invention, and a tire vulcanizing press according to the present invention.

[0238] The aspects of the present invention are shown by way of example in the drawings.
