Description

The invention relates to a manufacturing system for belt and / or carcass band in the tire industry, comprising a plurality of material-processing and / or material-conveying manufacturing components that can be controlled as a function of operating parameters, a control device for controlling the manufacturing components, and an operating device, wherein the control device comprises a monitoring device for monitoring the operation of at least one of the manufacturing components to be monitored, which monitoring device comprises at least one single-step component for carrying out single steps of a cycle for acting on the material. In addition, the invention relates to a computer program and an electronically readable data carrier.Manufacturing facilities in which a starting tape, in particular tacky cord tape, is processed into an endless tape as a manufacturing product, which is used as a belt tape or carcass tape in the tire industry, are fundamentally known in the prior art. Depending on the application wake, they can also be referred to as belt contact or carcass contact. The production plant can also be understood as a machine or device for processing a cord in the tire industry. From the starting tape, in particular the tacky cord tape, whether it be a textile cord tape or a steel cord tape, tape sections are separated and an endless tape is produced by splicing. The output tape is usually wound into a roll and taken up in an unwinding station, from which it is unwound and is first fed to scissors, i.e. to a cutting device, in which individual tape sections are cut from the output tape. Such a cutting device is known, for example, from DE 20 2013 103 082 U1. The leading edge of the output strip is gripped by a conveying device designed as a retraction device, which can also be referred to as a feed device and can have, for example, pliers, and is pulled by the cutting device, for example an impact scissors comprising a fixed lower blade and a movable upper blade, wherein the width of the strip section to be cut is defined over the pulling length. Such a conveying device or clamp or conceivable subcomponents thereof are described, for example, in DE 20 2013 102 341 U1 and DE 101 13 379 A1. The cut tape section can be moved by means of a receiving device to the height of a splicing device, as described for example in DE 20 2005 011 692 U1. It is taken up by a conveyor belt as a further conveying device, via which the output belt is pulled by means of the retraction device, i.e. the clamp, before the cut, and via which conveyor belt the respectively cut belt section is transported to the splicing device, in which the cut belt sections are spliced to one another to form an endless belt, but with a different orientation compared to the output belt. In the splicing device, the trailing edge of the band section previously spliced to the endless belt and the leading edge of the band section conveyed over the conveyor belt are positioned with respect to one another, after which the two edges are spliced to one another by means of a splicing device of the splicing device. For this purpose, the splicing device has, for example, a splicing tool which can comprise a splicing head or a plurality of splicing heads. In this case, the splicing head or heads are supplied from above to the edges previously positioned relative to one another. After the respective placing of the splicing heads, the strip material is pulled linearly, in the course of the splicing line, in the pressed state over the strip material in the direction of the lateral strip edges. The splicing heads can run loosely or be driven. When pulling over the strip material, it is compacted and thus spliced. In this way, an endless belt can be produced by splicing a plurality of individual belt sections together. Such a splicing device is known, for example, from DE 20 2014 101 735 U1.In a winding station, the production product can then be wound up, wherein further production components can optionally be provided after the splicing device in order to process the spliced endless belt. For example, the production plant can comprise a slide and / or a cover device. In a covering device, a rubberized strip can be applied to the cord strip as a spliced-together endless strip. Such a covering station has the task of reinforcing the produced material web, here the spliced cord, with additional material strips during the production process. In this case, rubber profile strips are placed centrally and / or offset in the material conveying direction on the material web to be reinforced. This process is continuous at the plant speed. The placement can be effected from above and / or from below. Furthermore, the outer edges of the material web are often enclosed, i.e. a rubber strip is placed with a protrusion from the outer edge and laid around the rubber edge in order to sheath the cords exposed at the outer edge (=cut edge). A documenting device is disclosed by way of example by DE 20 2014 101 731 U1.The production component Slitter is a longitudinal dividing device, i.e. the material web, here the spliced endless belt, is separated into at least two material strips in the production process if necessary. This serves to increase the output of a manufacturing facility. The preferred blade is a circular blade. The separating process is a cutting of the material web. In practice, the term "slap" is used. The Slapter production component is designed to separate an endless belt fed into at least two or more belt strips. The material web is cut into defined material widths which achieve identical or different strip strips. Slapter is described, for example, in DE 20 2013 104 649 U1, DE 20 2013 104 651 U1 and DE 20 2013 104 653 U1.The description of a production product which is to be produced in a production process by means of such a production plant is specified by an operating parameter set of operating parameters which are invariable for this production process and which is usually referred to as recipe or MES. In addition to a general recipe identification (recipe ID), a recipe can comprise, for example, the cutting angle to be used in scissors and the desired width of the material webs obtained as belt band or carcass band. A type of the output tape to be used may also be described by the recipe. A recipe is thus described mainly by the requirements for the production product and is independent of the specific production installation. However, it may contain requirements for the production speed and / or the output, i.e. the amount produced per unit time.If a problem occurs during the production of a belt or carcass band, for example a malfunction, damage and / or wear on a production component, restricted sensor data detection, a control error or the like, various, undesired effects can occur. Whereas in less problematic cases the output can be significantly reduced, for example, such deviations from the proper sequence of a manufacturing process frequently also lead to scrap production or in rare cases even to damage, possibly further damage, to a manufacturing component. It is therefore known to monitor the operation of manufacturing systems during a manufacturing process by a user on a regular or permanent basis, optionally supported by sensor systems, which can detect deviations from the desired manufacturing result, for example. Fine adjustment and optimization of the manufacturing process takes place by means of visual observation by a user, and therefore depending on the user, since there is often a different sensation. For many adaptations of operating parameters, the production facilities have to be stopped, which also applies to checking for potential problems. Manual and accurate detection during the manufacturing process is difficult. In this regard, the different interaction and the optimization of individual components is extremely varied on account of frequent recipe changes, that is to say changes in the product to be produced. Therefore, early detection of deviations during the manufacturing process by the user is additionally made more difficult. Predictive maintenance is not possible.The object of the invention is therefore to specify a simple, implementable, highly accurate and robust monitoring of the operation of a production installation for belt and carcass bands in the tire industry.To achieve this object, in a manufacturing system of the type mentioned at the beginning, it is provided according to the invention that at least one cycle time detection means for detecting a cycle time of the cycle is provided on the manufacturing component to be monitored and the monitoring device has:a monitoring unit for evaluating cycle times detected by the cycle time detection means with regard to the fulfilment of at least one action condition which indicates the presence of an abnormality in the production process, anda measures unit for performing at least one control measure which is associated with a fulfilled measure condition and relates to an output of an indication of the presence of the corresponding anomaly and / or an intervention in the production process relating to the anomaly.The operation of the manufacturing facility during the manufacturing process is described by operating parameters, wherein usually fixed and adjustable operating parameters are present. The attribute "adjustable" for operating parameters means in the present case that the value of the operating parameter can be changed during the production process of a specific production product which can be written by default parameters, that is to say an endless belt band or endless carcass band. In particular, these are operating parameters that can be set within a so-called recipe. A recipe fundamentally comprises operating parameters which are independent of the specific production installation and which at least describe the production product (i.e. comprise the specification parameters) and optionally can additionally describe production conditions, for example a desired output. Typical specification parameters can comprise, for example, a width of the production product, a general material specification and / or a cutting angle of the scissors (cutting device). A part of the operating parameters of a recipe can also be combined as a recipe ID.Operating parameters which define the recipe or would change it if it were changed cannot be changed during the manufacturing process for the manufactured product, i.e. during the implementation of the recipe. The operating parameters of the recipe are provided, for example in a recipe data set, at the beginning of the manufacturing process, for example loaded and / or input from a data carrier and / or server. The operating parameters of a recipe or generally operating parameters invariable during a manufacturing process can be understood as (part of) manufacturing conditions or describe such.An adjustable operating parameter does not have to be a control parameter (for example, to be converted into control signals) directly. Rather, more abstract adjustable operating parameters are also conceivable from which the control device derives at least one, optionally also several, control parameters. In particular, the more abstract adjustable operating parameter can be more intuitively comprehensible to the operator, for example specify a correction which is then specifically achieved by one or more control parameters.According to the invention, it is proposed to monitor manufacturing processes by means of cycle times which are detected by means of at least one cycle time detection means. The cycle time detection means can in particular form part of the control device and evaluate exchanged control signals, for example between control units and / or functional units of the control device. Particularly preferably, the control device is designed as a central control device for controlling the entire production plant, that is to say as a superordinate control entity. Particularly preferably, the monitoring also relates to a plurality of or even all production components.Cycle times are therefore detected by means of control signals, preferably with an accuracy in the millisecond range, for example with an accuracy of at least 10 to 1 ms. By evaluating the cycle times in process conditions which with particular advantage relate to known values from previous and / or optimized manufacturing processes, in particular compare them with these, deviations or anomalies in the current manufacturing process, as have shown studies within the scope of the present invention, can be detected in a particularly robust, accurate and early stage. This type of monitoring based on the cycle times can also be understood as a self-diagnosis of the production plant. Deviations or anomalies are detected early and can be made known to the user, for example an operator, on the basis of the control measures and / or can be weakened, in particular in a corrective manner, on the basis of the control measures, be it by compensating the deviations, protecting production components or their individual step components (for example by premature termination of the production process) and the like. Indications on the presence of the corresponding anomaly, in particular warning indications, can be output, for example, at output means of the operating device, for example by activation of a signal lamp and / or warning indications in a user interface for control purposes.The cycle times are preferably evaluated at least substantially in real time, i.e. with their presence, by the action condition(s), so that a decision about a control action to be carried out can be made promptly.At least one of the at least one action condition can also use a trained artificial intelligence evaluation function, in particular in the assessment of more complex questions. In this case, fundamentally known techniques of machine learning can be used.It has therefore been recognized, generally speaking, that in the production of belt and carcass bands, particularly many individual step components of the production components and the production components interact with one another in a highly accurate manner in a manner coordinated with one another in a wide variety of ways, wherein cycle times, in particular with regard to the individual steps (substeps) which will be discussed in more detail, react sensitively to deviations and can therefore display these in a highly accurate and reliable manner. In particular, this even allows localization of the deviation.In an expedient development, it can be provided that at least one further detection means is provided for detecting at least one further production value describing the operation of the production plant, wherein at least one of the at least one action condition additionally evaluates at least one of the at least one production value. For example, at least one of the at least one further production value can relate to a movement and / or a position of the processed material and / or the processed material itself and / or at least one processing condition, in particular a temperature. Detection means can comprise at least one sensor, for example, but can also query information inside the control device. At least one of the at least one production value can also be an operating parameter, for example a specification parameter of a current recipe and / or an adjustable operating parameter.It is therefore conceivable to also include other production values of the production installation in addition in the monitoring process. While, in principle, provision conditions are (additionally) conceivable which relate only to at least one production value and are used for monitoring, it may also be expedient to evaluate at least one production value and at least one cycle time jointly by means of a provision condition. If it is known, for example, that the cutting process takes longer for some materials, this can be mapped via a specific production value during the evaluation of the action condition. Known temperature dependencies can also be mapped, for example, into measures conditions if a corresponding production value is additionally included. Manufacturing values thus allow an even more accurate analysis.In this context, it may be provided with particular advantage that the detection of the at least one cycle time and the at least one action condition are related to a recipe-forming set of operating parameters of the manufacturing installation defined for the manufacturing process. In other words, the monitoring can take place in a recipe-specific manner, so that in particular action conditions can be related to manufacturing processes according to a specific recipe. This consideration of descriptions of a current manufacturing process allows even more accurate and more robust detection of deviations, i.e. anomalies, in the manufacturing process. For example, the control device can have a database in which it is possible to store, assigned to each recipe, which cycle times are to be recorded and / or which action conditions are to be used and / or how these are to be parameterized.In an expedient development of the present invention, it can be provided that the cycle time detection means is configured to request two successive control signals, in particular standby and / or trigger signals, of the at least one individual step component and / or of the production component for detecting the cycle time, and / or to determine at least one of the at least one cycle time as the duration of at least one of the individual steps. The latter means in particular that the cycle time detection means is configured to determine at least one cycle time as a time period between two successive, different control signals, in particular standby and / or trigger signals, limiting at least one individual step, during an action cycle. It is therefore proposed to use standby and / or trigger signals which are used in any case in the control device for at least some cycle times to be determined. This means that, insofar, at least one of the at least one cycle time detection means can be designed, for example as a detection unit of the control device, to monitor control signals exchanged within the control device, in particular standby and / or trigger signals, and to detect, in particular log, the corresponding point in time when a control signal to be logged occurs. The difference between two such successive points in time then results in a cycle time, in particular as the duration of an individual step. In other words and more generally, it can be provided that cycles of the production plant, i.e. standard sequences, are defined as time segments having a starting time logged in the presence of a control signal and an ending time logged in the presence of a further control signal. These time segments, i.e. total cycle times, are then divided even further into individual steps which likewise have start times and end times to be logged, which are defined, preferably exclusively, by the presence of control signals. The cycle times thus recorded are then evaluated in a higher-order control. In this case, it is also possible with particular advantage to provide the sum of all individual step cycle times of a cycle as a total cycle cycle time, which will be discussed in more detail below. By dividing into individual steps and detecting, in particular logging (logging), cycle times for the individual steps, a more accurate analysis is made possible where the anomaly is present. The individual steps are expediently defined such that deviations from an expected cycle time, in particular for a recipe, can already be assigned to specific anomalies within the scope of the evaluation. If, for example, an individual step is defined in which the material to be processed is to be magnetically lifted by interaction with a magnetic element arranged below the material, typical deviations can occur as a result of slipping of the element arranged below the material, i.e. if, for example, the magnetic force does not directly "grip". Conveying sections can be assigned, if appropriate in the case of a longer period, to a poor grip of the conveying individual step component and / or material slipping back, and the like. It should also be pointed out here that individual step components cannot necessarily be assigned to a single individual step, but it is quite conceivable for an individual step component to carry out a plurality of individual steps and / or to be involved in a plurality of individual steps. An example of this is a lifting device of a cutting device or scissors and / or of a retraction system, which can be used, for example, both as a holder and as a hold-down device in various individual steps. Furthermore, it should also be noted in general terms that, in some cases, single-step components of other manufacturing components can also participate in a cycle of a manufacturing component and / or can supply or receive control signals. Consequently, the control signals do not necessarily originate from the production component to be monitored and / or have to be directed to the latter.Therefore, in the case of at least one cycle time related to at least one individual step, the monitoring unit can preferably be configured to assign an anomaly to at least one individual step and / or at least one action condition can be formulated to display an anomaly to be assigned to at least one individual step when fulfilled. However, quite complex evaluations and / or action conditions can be used here, which can also take account of other individual steps of their cycle (and / or of an adjacent cycle) and their cycle times, for example, since anomalies in certain individual steps can also have effects on the cycle times of other individual steps. Action conditions can be at least partially selectively formulated to be directed to the detection of anomalies in certain single steps and / or single step components.In this case, a hierarchy of the evaluation processes and / or action conditions is also particularly advantageously conceivable, wherein the superordinate evaluation processes and / or action conditions relate to the total cycle time. For example, it can be provided that firstly a measure condition related to the total cycle time is evaluated, which measure condition indicates the presence of an anomaly when the measure condition is fulfilled, wherein subordinate measure conditions related to single-step cycle times are evaluated when the measure condition is fulfilled, in order to localize the anomaly in at least one single step and / or one single-step component, if possible. It should be noted that this hierarchy can also be continued, for example total times can be determined and evaluated for a plurality of successive cycles, for example entire production components or groups of production components. For example, a total time over all production components is also conceivable and detectable, wherein in the case of an abnormality in the latter, the system can then proceed stepwise in the hierarchy to subordinate total times, in particular total cycle cycle times, and then to single-step cycle times.Exemplary embodiments may provide that at least one of the at least one standby and / or trigger signal is a completion signal from at least one supporting single-step component, in particular a holder and / or a hold-down device and / or a lifting device and / or a positioning device, to a material-conveying and / or material-processing single-step component, in particular a conveyor belt and / or a gripping device and / or a cutting means and / or a binding means and / or a material-adding means, and / or is a start signal for a single-step component. Other examples of control signals that can be detected in order to determine cycle times also include start signals of the control device and / or of another production component for the basic start of the cycle.In a preferred embodiment, at least one of the at least one action condition can be a limit value condition which compares at least one of the at least one cycle time with an associated upper limit value and / or an associated lower limit value. In the case of the upper limit value, an exceeding is necessary to fulfil the action condition, and a falling below is necessary in the case of the lower limit value. In this case, it is thus checked whether the cycle time is within at least one expected limit. Different approaches are conceivable in this case in order to arrive at the limit values.Thus, in a first embodiment variant of the present invention, it can be provided that at least one of the at least one limit values, in particular for at least one recipe, is permanently predefined. In this case, a comparison is therefore made with permanently stored limit values in order to indicate anomalies. Such limit values can be set or determined, for example, on the basis of limits theoretically set or determined during the design of the production plant, in particular for the respective recipe, and / or during test runs, in particular on the manufacturer side. Such intervals, in which the cycle time is to move, are usually selected to be somewhat broader, since local and / or current peculiarities cannot be taken into account. They are therefore particularly suitable if there are still no empirical values at the specific production plant, for example for the specific recipe.In a second design variant, it can additionally or alternatively be provided that the monitoring device has a determination unit for determining at least one learned of the at least one limit value in a learning phase of the current and / or of a reference manufacturing process which is at least receptive. It can therefore be provided that the at least one limit value is determined, thus learned, so to speak, in at least one manufacturing process on the same manufacturing facility. Specifically, it can be provided that the learning phase for at least one learned limit value is a sliding time window ending at the current time or at a predefined time interval before the current time and / or the learning phase for at least one learned limit value is a time period beginning, in particular after an inlet phase, at the beginning of the current manufacturing process or of the reference manufacturing process and / or a reference manufacturing process complete, at least after the inlet phase, in particular the first of a recipe. For example, during the first pass of a manufacturing process for a recipe, if no or only the above-mentioned permanently predefined limit value is still present, it is possible to monitor in which frame cycle times move during a normally running manufacturing process. In this case, in principle, an inlet phase is preferably waited for, for example a specific number of cycles, in particular 5 to 30, in which, in particular monitored by a user, the production installation has to run continuously before the stable, normal production state is reached and can be used for learning limit values. Such an inlet phase can in principle also be set before the beginning of the monitoring. Expediently, however, the limit values can be updated further and further as long as the production plant runs stably. In this way, improvements, readjustments and the like, for example, brought about by the user, can also be taken into account. Nevertheless, a certain time interval should then expediently be maintained at the current time, since some anomalies can form slowly and could therefore possibly be "learned", which can be avoided by the time interval. For example, the learning phase can always reach back until the end of the last successfully completed production process. In the learning phase, the cycle times are also advantageously advantageously advantageously recorded together with at least one, in particular the at least one, further production value, in order to be able to set them in conjunction with the production conditions and other circumstances. In other words, the cycle times are preferably detected, in particular also during monitoring, in conjunction with all movements and sensor interrogations at the production installation. Thus, in particular when the action conditions also query production values, even improved and more accurate evaluations can be carried out. However, even generally, learning from preceding manufacturing sections, in particular from the same recipe, achieves a distinct improvement in the monitoring, since the normal state at a specific manufacturing plant can be specifically focused on.During a learning phase, monitoring can certainly also be provided, that is to say during which at least one learned limit value is determined, currently detected cycle times can also be monitored, for example, with regard to the predefined limit values according to the first design variant and / or other provided action conditions.For example, it is conceivable, in the case of a new recipe for which the at least one limit value is to be learned, to use action conditions of a similar recipe, in particular of the most similar recipe for which a comparison hierarchy can be defined. If, for example, the desired width of the endless belt to be produced only marginally differs from that of the current recipe, a high similarity can be assumed. Action conditions of similar recipes can optionally be modified, for example attenuated with decreasing similarity depending on a similarity measure. It is understood that when, for example, due to the use of a sliding time window, an update of limit values takes place, the previous limit values are of course basically used for monitoring.It should be noted that it is fundamentally advantageous to analyze a curve of the cycle times over an evaluation time window. For example, a drift of cycle times over time can also indicate an anomaly. A trend that results over an evaluation time window may indicate an increasing wear or the like. Accordingly, the system conditions and possibly further evaluation processes can be configured to evaluate not only the current value of the cycle time, but rather the profile over an evaluation time window, which can also be different from system condition to system condition.Generally speaking, the recorded cycle times can also be usefully evaluated beyond the detection of anomalies that are currently present. Thus, a preferred embodiment of the present invention can provide that the monitoring device further comprises an evaluation unit which is configured for evaluating cycle times recorded in a storage means of the monitoring device over at least a period of time, in particular the course thereof, for determining optimized operating parameters of the production plant and / or for terminating a predictive maintenance. This means that the evaluation of the cycle times, in particular together with at least one production value, can also be used to improve, in particular optimize, the production process since cycle times can describe an improvement potential in addition to anomalies. In addition, the cycle times, in particular trends in their time profile, can also be evaluated as to when in the future maintenance could be expedient, which can then be set up early without a (not planned) failure of the production plant possibly occurring. Overall, the cycle times are also supplied in this way for further purposes, and are therefore used in a multiply advantageous manner. For example, in the evaluation unit, comparable to the action conditions for anomalies, optimization conditions and / or maintenance conditions, corresponding optimization and / or output actions for adapting (adjustable) operating parameters and / or for indicating maintenance to be scheduled can be assigned to said optimization and / or output actions.In a development, the manufacturing installation can furthermore comprise a display device, in particular as part of the operating device, and the control device can be configured for at least partially outputting the at least one cycle time and / or an item of information derived therefrom on the display device, in particular within a user interface for operating and monitoring the manufacturing installation. Specifically, it can be provided, for example, that the output comprises an indication of the current cycle time with at least one comparison value, in particular the upper and / or the lower limit value. Furthermore, the display can also comprise a profile of the cycle times, in particular also over a plurality of production processes as the respective mean value. In this way, a user can also observe, monitor and draw conclusions about the cycle times, which may not be covered, or not yet covered, by action conditions and / or the further evaluation, for example for optimization. In addition, it constantly receives an overview of the production installation and to what extent the production process runs within normal parameters.As is fundamentally known for generic manufacturing systems for belt webbing and / or carcass webbing, the manufacturing system according to the invention can also preferably provide that the manufacturing componentsan unwinding station for an output tape, in particular a cord tape,a shear for cutting portions of tape at a predetermined angle and a predetermined width from the output tape from the unwinding station,a withdrawal device for conveying the output strip through the scissors,a splicing device, in particular a butt splice or an overlap splice, for connecting the strip sections cut by the scissors,at least one winding station for the belt and / or carcass band, andat least one conveying devicecomprising.A scissors table of the scissors can serve as a material support, which can also be provided in another way. In addition, the production installation can comprise at least one optional production component, for example a pacifier roll and / or a repair tape. Further optional production components can comprise a slide and / or at least one documenting device.It has proven to be particularly advantageous if at least the retraction device and / or the scissors (cutting device) is a production component to be monitored. This is because, in the case of the retraction device and / or scissors, in particular in their interaction, a multiplicity of individual steps follow one another, which in each case require readinesss or other trigger signals and can indicate specific anomalies at many points if the individual steps of the cycle through which the retraction device and / or scissors pass are all monitored accordingly by cycle times. In this case, for example, a start signal is initially started, which indicates that the material is to be drawn through the scissors for a predetermined length (which can correspond to the recipe specification parameter material width). Before this can be done, however, further individual steps are required. Thus, a ready signal from the unwinding station may be next waited for, indicating that sufficient material is prepared in a loop to be pulled. A next individual step can now be defined by the end time that a hold-down device signals that it is in position, and therefore the material is in the transfer position. Further individual steps can relate to the readiness, i.e. completed positioning, of a lifting device and of a holder. After positioning the lifting device, a clamp can grasp the material, which can also be queried in exemplary embodiments. Optionally, in a further single step, a receiving device can then be positioned for the further conveyance of the cut material to the splicing device and the corresponding completion signal can be waited for. As a final single step, the forceps may actually draw the material through the scissors by the predetermined length, whereupon a ready signal for cutting may be provided to the scissors. After the cut-off material section has been started to be transported away, the clamp then moves forward again to the scissors, in order then to wait for new material to be gripped in the next cycle. All of these control signals, which indicate triggers, completion or readiness and the like, can now be detected by the cycle time detection means, for example a detection unit of the control device, wherein the corresponding time stamp, which describes a start time or end time of an individual step, is logged (time stamp). The differences result in the cycle times, wherein the total cycle cycle time also results as the difference between the first starting time and the last ending time. Consequently, a cycle for the retraction, in particular thus the retraction device and / or the group of retraction device and scissors, can relate to the partial production process of gripping and retracting the material for a material section to be cut off by the scissors. Exemplary anomalies that can be detected by these cycle times, optionally together with at least one production value, on the basis of action conditions compriseincorrect cutting of the scissorswear of the axles of the retraction device and / or scissorsnecessary correction for setting the clampmaterial feeding is not correcthold down system failurewrong section widthMaterial slips backwear on the pliers segmentuser input errors in operating parameters such as axis parameters of the retraction device and / or scissors and / or speeds of the retraction device and / or scissors.Of course, further possibilities are also conceivable. The knowledge relating to the wear can also be processed and / or obtained in the evaluation unit with regard to maintenance, for example by the maintenance condition.Cycle time analysis is not limited to the retractor and / or scissors. For example, it is particularly advantageous if (further) cycle times of the scissors are also detected in parallel with the retraction device (and / or the scissors), wherein at least one action condition evaluates in each case at least one cycle time of the retraction device and the scissors together in order to determine a specific anomaly and / or at least one cycle time of the scissors is determined on the basis of at least one control signal which is also used to determine a cycle time of the retraction device. For the scissors, some control signals which have been used with respect to the retraction device for defining individual steps and associated cycle times can likewise be used. In the splicing device as well, different cycle times can be logged, for example the arrival of the material, the lowering of the actual splicing head and the like. It should be noted that, even if the cycle overall concerns an effect on the material, i.e. strip, not every individual step has to act directly on the material.It should be noted that, within the scope of the invention, it is also possible to provide interaction with control mechanisms, for example insofar as the compensation of control deviations can have an influence on expected cycle times. Thus, for example, it can be provided that at least one of the at least one action conditions is adapted as a function of a control deviation of at least one control loop of the production plant. The type of adaptation, for example of the upper and the lower limit value, can be determined empirically, for example, by the cycle times in the learning phase being recorded and evaluated in association with these in the event of deviations in the rule.In addition to the manufacturing installation, the present invention also relates to a computer-implemented method for monitoring the operation of a manufacturing installation for belt and / or carcass band in the tire industry, wherein the manufacturing installation has a plurality of material-processing and / or material-conveying manufacturing components that can be controlled as a function of operating parameters, a control device for controlling the manufacturing components and an operating device, wherein the control device has a monitoring device for monitoring the operation of at least one of the manufacturing components to be monitored, which monitoring device comprises at least one individual step component for executing individual steps of a cycle for acting on the material. According to the invention, the method has the following steps during a production process:detecting a cycle time of the cycle at the at least one production component to be monitored by at least one cycle time detection means,evaluating cycle times detected by the cycle time detection means with regard to the fulfilment of at least one measure condition which indicates the presence of an abnormality in the production process, andperforming at least one control measure which is associated with a fulfilled measure condition and relates to an output of an indication of the presence of the corresponding anomaly and / or an intervention in the production process relating to the anomaly.All embodiments with respect to the production plant according to the invention can be transferred analogously to the method according to the invention and vice versa, so that the already mentioned advantages can also be obtained with the method.A computer program according to the invention can be loaded directly into a storage means of a control device of a manufacturing system for belt and / or carcass band and has program means such that, when the computer program is executed on the control device, the latter is caused to carry out the steps of a method according to the invention. The computer program can be stored on an electronically readable data carrier according to the invention, which therefore comprises control information stored thereon, which comprises at least one computer program according to the invention and are configured such that, when the data carrier is used in a control device of a manufacturing system for belt and / or carcass band, said control information is configured to carry out a method according to the invention. The data carrier can be a non-transient data carrier, for example a CD-ROM.Further advantages and details of the present invention are evident from the exemplary embodiments described below and on the basis of the drawings. The following are shown: FIG. 1 shows production components of a first exemplary embodiment of a production plant for carcass band according to the invention, FIG. 2 shows production components of a second exemplary embodiment of a production system for belt webbing according to the invention, FIG. 3 shows production components of a third exemplary embodiment of a production plant for carcass band according to the invention FIG. 4 shows production components of a fourth exemplary embodiment of a production system for belt webbing according to the invention, FIG. 5 shows control and operating components for the first and second exemplary embodiments, FIG. 6 shows a flow chart of an exemplary embodiment of the method according to the invention, FIG. 7 schematically shows a first state diagram for explaining the method, FIG. 8 schematically shows a second state diagram for explaining the method, FIG. 9 schematically shows a third state diagram for explaining the method, FIG. 10 schematically shows a fourth state diagram for explaining the method, FIG. 11 schematically shows a fifth state diagram for explaining the method, FIG. 12 schematically shows a sixth state diagram for explaining the method, FIG. 13 schematically shows a seventh state diagram for explaining the method, and FIG. 14 shows a possible display in the user interface.FIGS. 1 and 3 show exemplary layouts for a carcass installation without or with layers as first and third exemplary embodiments of a production installation according to the invention.The carcass installation comprises an unwinding station 1, from which the cord band to be treated is obtained as a starting band. In the unwinding station 1, the material rolls to be processed are suspended in a suitable frame and unwound. Here, the cord web to be processed is separated from an intermediate layer (film, linen or the like). This intermediate layer is used to prevent the adhesive bonding of the material web rubberised here. In order to realize different cutting angles, the unwinding station 1 can be pivoted as explained, which is not absolutely necessary, however. There are different embodiments with respect to such a scheduler. Single unwinders are known, into which a roll of material can be suspended. In a double winder with a rotary table, two rolls of material are provided for suspension, one of which is processed and one of which is changed. In addition, a double winder with shuttle frame for hanging two material rolls, one of which is processed, one of which is changed, is known. Furthermore, cassette winders are known in which a roll of material is suspended in a cassette and the cassette is then transported into the winder. This list is not exhaustive. The unwinding station 1 can form a material loop and can be kept ready for take-off.The pivotable unwinding station 1 is followed by a cutting device or scissors 3 which serves for cutting the cord strip coming from the unwinding station 1. The scissors 3 serve for cutting cord strips at a defined width and a defined angle. Various configurations can be used as scissors 3:Guillotine scissors with a fixed lower knife and an upper knife which can be moved up and down,round-blade scissors having a fixed lower blade and a round blade running along it, andshearing with a rapidly rotating saw blade (similar to a circular saw blade).Depending on the material to be processed, different types of scissors are used. It is decisive in this case which cord material (whether textile or steel cord) and in which angle it must be cut (carcass or belt type of installation), wherein in this example a scissors 3 is used for a carcass installation.The material support 2 is connected to the unwinding station 1. It pivots together with it when required. The material to be processed lies on the material support 2 and is drawn into the scissors 3 lying thereon. At the beginning of the material support 2 or above it, there is very frequently a conveying device which transports the beginning of the material into the scissors, for example a driven conveying roller. This is always necessary when the manufacturing plant is completely emptied and the beginning of a new material roll has to be inserted into the scissors 3, or if the material has been pulled back a certain distance from the scissors 3 in order to pivot the unwinding station 1.Relevant for the scissors-type construction is, in particular, the sequence after cutting. In order to integrate the cut material, i.e. the strip sections, into the subsequent process with a few processing steps, further production components or single-step components of production components, such as strips and holders, are used. These further manufacturing and / or single step components should be as close as possible to that of scissors 3 (which also forms a manufacturing component). For this purpose, the material should be moved as little as possible (in particular with regard to a drop height) in order to further process it in the cut storage position.In order to convey the material through the scissors 3, a retraction device 4 is used in most cases as a production component. In this case, for example, a gripping device (pliers) as the single-step component must be moved very close to the lower blade. For this purpose, a certain space requirement is required in order to avoid collisions with the upper knife (or round knife). This results in different designs of the scissors 3.The retraction device 4 serves for conveying the material web into the scissors 3 or pulls the gripped cord band through the scissors 3, as described above. The scissors 3 further comprise a conveyor belt which receives the cut cord band section and transports it out of the scissors 3. Such a conveyor can be designed as a single belt, in the form of a plurality of belt belts or in the form of a plurality of belt belts with an interposed lifting device.The corded section is then fed onto a first conveying device in the form of a belt 5 of a splicing device 7, here an overlap splicer 14, and fed to the actual splicing unit. For this purpose, a receiving device can also be provided, as described above with reference to DE 20 2005 011 692 U1. This first conveying device 5 can also basically coincide with the conveying device which is associated with the scissors 3, so that only one conveying device is located between the actual lap splice 14 and the scissors 3, which conveying device then is the first one with respect to the lap splice 14. The lap spliceer 14 serves for connecting (purely mechanically, without the aid of additives) the previously cut strip sections. It is pivotable at an angle in order to be able to process the strip material at various angles.Optionally, a further splicing device in the form of a butt splice 15 is provided as part of the splicing device 7, which can be used instead of the lap splice 14 if this type of splicing is required.Downstream of the lap spliceer 14 or its second conveying device (or the alternative butt spliceer 15) is an optionally provided settling roller 9, which is merely a driven roller which transports the spliced cord band, which comes from the splicing device 7, into the next production component. In this case, the spliced cord undergoes counterbending by being transported over the pacifier roll 9. The counterbending pulls the material together in the longitudinal direction. The background is thus to reduce the elongation of the material in the longitudinal direction during processing in the splicing device 7 according to the invention. During the removal, the next strip section is already cut in the scissors 3.In the third exemplary embodiment according to FIG. 3, a sleeve 10 is then provided downstream of the (optional) pacifier 9 as a further production component, which splits the spliced cord band into two, in particular identically sized, subbands. For example, a cutting unit can be arranged on a framework, which serves for separating the supplied spliced cord band into at least two cord band strips. Usually, two cooperating circular knives are provided for this purpose. Furthermore, a control frame can be provided which is pivotable about a vertical pivot axis relative to the frame structure. The cord runs over the control frame. It passes from the control frame into the region of the cutting unit where it is divided into the two cord strips. Other variations are also conceivable.According to FIG. 1, the optional settling roller 9 is followed by an equally optional lining device 12, according to FIG. 3, two likewise optional lining devices 12 are arranged in accordance with the slider 10, and in this production component, still further rubber strips, for example one to twelve pieces, are placed on the material web produced, that is to say the spliced-together corded strips, also split in the third exemplary embodiment. The placement can be effected from above and / or from below. Furthermore, the outer edges of the material web are often enclosed, i.e. a rubber strip is placed from the outer edge without or with a protrusion and laid around the rubber edge in order to sheath the cords exposed at the outer edge corresponding to the cut edge.In each case, one winding station 13 is provided in the case of FIG. 1 or two winding stations 13 are provided in the case of FIG. 3. In these production components, the corded strips, which may have been split, are wound again on spools with an intermediate layer which prevents the adhesive bonding. Here too, there are various embodiments which extend from quite simple single winders, in which the material has to be cut off manually and wound up on a new roll, to fully automatic winders, in which no operator interventions are necessary for the material handling.FIGS. 2 and 4 show exemplary layouts of belt systems once without and once with layers 10 as second and fourth exemplary embodiments of a production system according to the invention. Production components that have already been described in the layouts of FIGS. 1 and 3 are provided with the same reference numerals, if provided, and their function is the same as described with reference to FIGS. 1 and 3.An unwinding station 1 is provided, which can be pivoted here, however, by a significantly larger angle. The scheduler may be of any type as described previously.The unwinding station 1 is followed by scissors 3. The material support 2 is connected to the unwinding station 1. It pivots together with it when required.The scissors 3 serve for cutting cord strips at a defined width and a defined angle. As scissors 3, the types of scissors described above can be used as far as they are suitable for belting.The scissors 3 are followed by a retraction device 4 as described above. It serves for conveying the material web into the scissors 3 or pulls the gripped output band through the scissors 3, as described above.The corded section is then fed onto the first conveyor (in the form of a belt 5) of a splicing device 7, which may comprise an overlap or butt splice, and fed to the corresponding actual splicing device. The splicing device is pivotable through a considerable angle for setting the required splicing angle. It also has a removal belt 6 as conveying device, with which the spliced cord is fed to the downstream production component.Optionally, a band 8 for hand splicing, i.e. for manually connecting the band sections, can also be connected downstream of the splicing device 7. During this manual operation, the automatic splicing device 7 is out of operation. Such hand splicing is required for certain corded materials, very narrow section widths or on the demand of a customer. Optionally, a settling roller 9 can also be provided in the second exemplary embodiment.In the exemplary embodiment of FIG. 4, a slitter 10 follows as a further production component. the separation of the spliced material web effected via the slitter 10 has the result that in this case two winding stations 13 are to be provided, each of which optionally can be preceded by a respective lining device 12 and / or a repair tape 11. In the case of FIG. 2 without the slapper 10, these production components are only required once. If defects in the tape are detected, they can be repaired by means of the repair tape 11.Although in these and also subsequent representations the cord band is conveyed from right to left, it is of course possible to design the layout also in a reversed, mirror-image embodiment, i.e. to transport the cord band from left to right. All the manufacturing components described as optional may be provided in different combinations together with the essential manufacturing components. Therefore, different layouts can be produced from all described production components.FIG. 5 schematically shows the control, operating and monitoring structure of the manufacturing installation, in particular thus of the belt installation or of the carcass installation. In addition to the arrangement 16 of production components, the production installation has a control device 17 which in the present case comprises a monitoring device 18 and optionally further components. The operation of the production components of the arrangement 16 can be controlled via the control device 17. The control device 17 is also connected to an operating device 19 via which user inputs of a user / an operator can be received. The operating device 19 also has a display device 20, in the present case a display or screen. It should be noted that a user interface may also be provided via an Internet access or the like. The control device 17 and the operating device 19 can be embodied at least partially integrated, that is to say components of the control device 17 can be installed in structural units or assemblies of the operating device 19 and vice versa.The control device 17 and / or the operating device 19 additionally comprises a storage means 21 in which, in addition to other information, operating parameters (or specifically their values), cycle times and production values (which may at least partially correspond to values of operating parameters) and also action conditions may be stored. In this regard, it should first be noted that a manufacturing process for producing a specific manufactured product is usually based on a so-called recipe which comprises specification parameters which describe the manufactured product (for example, cutting angle of scissors 3, desired width) and optionally further operating parameters, for example, an output to be achieved. The operating parameters described by the recipe of the current manufacturing process are usually not modifiable during the manufacturing process. They can be input at the operating device 19 and / or read out from a data carrier and / or server, for example.Within the scope of a manufacturing process carried out for the implementation of a specific recipe, there are also adjustable operating parameters, i.e. operating parameters which can be selected by the user, for example. During operation, adjustable operating parameters can be automatically adjusted by the control device 16, for example by means of regulations, but at least partially also by the operator by means of the operating device 19. changes of the operating parameters, for example starting from a base set for a recipe, basically serve to optimize the manufacturing process or the manufacturing product.The control device 17 and its control operation are superordinate, i.e. they record all production components of the arrangement 16.The monitoring device 18 serves to monitor the operation of the manufacturing installation during a manufacturing process according to a specific recipe. In this case, it uses cycle times for at least one production component to be monitored, which cycle times are detected as input data from at least one cycle time detection means 22, wherein in the present case at least the unwinding station 1, the scissors 3, the retraction device 4 and the splicing device 7 are production components to be monitored. Other production components, such as the slide 10, the covering device 12, the repair tape 11 and the like, can of course also be monitored.In the exemplary embodiments discussed in more detail here, the cycle time acquisition means 22 is formed by an acquisition unit of the control device 17 and queries control signals, for example standby signals, trigger signals and the like, from production components and / or their individual step components, the time stamps of which describe the start times and / or end times of cycle times. Starting times and / or ending times can also be detected at least partially by cycle time detection means of the arrangement 16 itself, for example sensors and / or other encoders.In this connection, it should already be noted that production components pass through a repeating respective cycle during the production process, for example the cutting device / scissors 3 repeatedly cut off material sections, the withdrawal device 4 repeatedly pulls material through the scissors 3 and the splicing device 7 repeatedly splices material sections together to form the endless belt. These cycles are each formed by individual steps, wherein in the present case a cycle time is determined for each of these individual steps. This means that the sum of the cycle times of the individual steps (individual step cycle times) corresponds to the total cycle cycle time, that is to say the duration of a cycle. The individual steps are carried out here in particular by individual step components of the production components, here the retraction device 4 and the scissors 3. For example, a clamp or clamp arrangement can be assigned as a single step component to the retraction device 4, a lifting device and a holder as a single step component to the scissors 3.Optionally, in addition to the cycle time acquisition means 22, further acquisition means 23 can also be provided, which are designed to acquire at least one production value, which is to be evaluated together with at least one of the cycle times. Production values can be, for example, operating parameters which are present or used in the control device 17, but also describe production circumstances detected by sensors, for example temperatures, movements and positions of the material, processing conditions (for example a temperature) and the like.In order to be able to evaluate the cycle times detected, the monitoring device 18 of the control device 17 in the present case firstly comprises a monitoring unit 24. the monitoring unit 24 checks the fulfilment of action conditions which evaluate in each case at least one cycle time and, if fulfilment, indicate the presence of an abnormality in the production process. Each action condition is assigned at least one control action which is carried out by a action unit 25 of the monitoring device 18 when the action condition is fulfilled. The at least one control measure can relate, for example, to the output of an indication of the presence of the corresponding anomaly, for example a warning indication, but also to an intervention in the production process relating to the anomaly, for example the adaptation of an adjustable operating parameter, the omission of an optional single step or, in extreme cases, an emergency stop, that is to say an at least temporary and / or partial interruption of the production process.The monitoring device 18 also permits a further evaluation of the cycle times in an evaluation unit 26. For example, the presence of at least one drift of at least one cycle time can be checked. When the maintenance condition is fulfilled, the predictive maintenance is terminated. The cycle times are also evaluated in the evaluation unit 26, however, for optimizing the manufacturing process, for example for adapting set operating parameters of the current manufacturing process and / or future manufacturing processes of the same recipe.It should be noted in general that any evaluation in the monitoring device takes place in a recipe-related manner, that is to say cycle times, action conditions and / or maintenance conditions / optimization processes to be recorded are all formulated for a specific recipe.Specifically, it can be provided here, for example, that initially for a recipe for which no manufacturing process has yet been carried out on the manufacturing installation, predefined action conditions (and also, if applicable, evaluation parameters of the evaluation unit 26) are used, for example based on test runs, other manufacturing installations and / or similar recipes. Since the conditions of action can be, in particular, at least partially limit value conditions in which at least one of the at least one cycle time to be evaluated is compared with an upper and / or a lower limit value, predefined limit values can describe, for example, fundamentally expected intervals for specific cycle times.In the exemplary embodiments described here, however, it is provided to learn the normal sequence of the corresponding manufacturing process on the specific manufacturing system for a specific recipe, optionally also continuously, in order to be able to detect anomalies in a particularly accurate, reliable and robust manner. For this purpose, in a learning phase-possibly with parallel monitoring on the basis of the predefined action conditions-the cycle times are recorded, possibly with the respective production values. The learning phase can comprise, for example, at least part of a reference manufacturing process which begins after an inlet phase, optionally the entire first manufacturing process of a specific recipe (without an inlet phase). For example, to begin the learning phase, it can be required that at least a predetermined number of cycles have been run through without termination / restart, in particular that at least ten splicing processes have taken place without termination.However, a sliding time window is also conceivable as a learning phase in continuous learning, although in order to avoid learning of drifts indicating an anomaly, a predefined time interval should be maintained at the current point in time. For example, after confirming that this has run normally, the preceding manufacturing process of the same recipe can always be evaluated in order to determine or update the suitable action conditions, in particular the limit values. It should be noted that when limit values are used, these may be dependent, for example, on a production value which is likewise to be evaluated by the respective action condition. The determination of action conditions in general and limit values in particular can be carried out by a determination unit 27 of the monitoring device 18.Expediently, the conditions of action can be formulated such that a concrete conclusion is also obtained which describes the detected anomaly in more detail. This means that in the case of specific deviations / violated limit values, for example, specific errors or other anomalies can be deduced more accurately. This is possible in particular expediently and in more detail on account of the division of the cycle into individual steps and the determination of cycle times for these individual steps. It can also be expedient to classify action conditions hierarchically, for example to check first for the total cycle time whether the presence of an anomaly is generally indicated, according to which subordinate action conditions seek to classify or locate this anomaly more precisely.It should be noted that, also generally speaking, particular advantages can result if at least one action condition also evaluates at least one cycle time of both production components at least for production components having and / or functionally interacting cycles running at least partially in parallel, since this can contribute to an even more accurate assignment and / or classification of a detected anomaly. This can relate, for example, to the retraction device 4 and the scissors 3. It is also conceivable to combine cycle times on more than two production components. It should also be pointed out that, for the purposes of the integration already mentioned, the units 22, 24, 26 and 27 can be implemented, for example, in a structural unit or assembly which is assigned to the operating device 19 and can contain the display device 20, for example.An exemplary embodiment of the method according to the invention for monitoring the operation of the production plant is now discussed below, wherein a focus is placed on the retraction device 4, which can also use individual step components of the scissors 3, with respect to which individual steps that are possible purely by way of example are illustrated. It is of course also possible in this regard to use a wide variety of modifications, which are fundamentally known in the prior art, with regard to the structure of the retraction device 4 and the specific individual steps. In other words, the specific example presented here is to be understood as merely illustrative.As FIG. 6 shows, in a step S 1, a new manufacturing process starts to form a specific recipe, which is also logged accordingly, i.e. is stored in the storage means 21. In the present case, it is assumed that there are already action conditions, in particular learned limit values, for this recipe.In a step S 2, it is then checked whether the production plant is running in a stable manner, and therefore an inlet phase is concluded. For this purpose, it is necessary for ten cycles to have been run through without interruption, that is to say in particular for ten splices to have been produced without interruption.If this is the case, the monitoring, in particular also the detection and evaluation of cycle times, is enabled in a step S 3. If no ten splices are successful without interruption, the process is started again until this is successful.Consequently, the cycle times are now detected by the cycle detection means 22 and production values are detected in parallel by the further detection means 23. This is shown in more detail only by corresponding steps S 4 to S 10 for the retraction device 4 and otherwise, for the sake of simplicity, is subtracted by step blocks 28. Step blocks 28 are additionally provided at least for the unwinding station 1, the scissors 3 and the splicing device 7, preferably also for further production components.In a step S 4 in the step block 28 for the retraction device 4, a general start signal / trigger signal is initially detected, which can indicate, for example, that a clamp or clamp arrangement has moved into a position close to the cutting unit of the scissors on each cycle after the first cycle, and the time stamp of which logs as the start time of the first single-step cycle time. The state at this starting time is explained in more detail schematically by FIG. 7, wherein, for the sake of simplifying the illustration, only the upper knife 29 and the lower knife 30 of the scissors 3, a tong arrangement (tong for short) 31 of the retraction device 4 and the material 32 are indicated in an abstract manner.The general start signal instructs the withdrawal device 4 to draw material through the scissors 3 by a predetermined length, which is determined by the recipe specification parameter of the width, for which purpose, however, individual preparation steps are necessary. The start signal thus acts simultaneously as a trigger signal for the unwinding station 1 or a corresponding single step component ("letoff") of the unwinding station 1, in order to provide a sufficient amount of material in a loop. Once this has occurred, it sends a completion signal or standby signal, the time stamp of which is stored in a step S 5 as the end time of the first individual step and the start time of the second individual step in turn by the cycle time acquisition means 22, in particular the acquisition unit. At this point in time, the first cycle time for the first individual step can already be provided in principle.The corresponding state is again shown purely schematically and abstractly in FIG. 8, where the loop 33 formed is now additionally shown. In this case, therefore, an external single-step component of the unwinding station 1 is also involved in the work of the retraction device 4.The ready signal of the unwinding station 1 applies to an individual step component of the retraction device 4 and / or of the scissors 3, for example a lifting device also acting as a hold-down device, as a trigger signal in order to move this individual step component into a transfer position. If this is the case, the single-step component then sends a corresponding ready signal, whose time stamp is again logged in step S 6. The corresponding time point forms the end time point of the second individual step and the start time point of the third individual step.FIG. 9 illustrates the corresponding state with the single step component 34 as a hold-down device in position.In the next following third individual step, a control signal (ready signal) of an individual step component acting as a holding-up bar is waited for, which in this third individual step is therefore moved into a desired position, for example at the current height of the material 32. The state arising is indicated in FIG. 10, wherein it should be noted that the single step component 35 shown abstractly there corresponds in many cases to the single step component 34, that is to say to the already mentioned lifting device. The time at which the ready signal "hold-up bar in position" is present is logged as the end time of the third individual step in step S 7 and also serves as the start time for the fourth individual step.In the fourth single step, a holder of a single step component 36 is moved into position, wherein the reaching of this position behind the scissors 3 is again indicated by a corresponding ready signal. In this fourth individual step, it is also included in the present case that the clamp 31 grips the material 32 (which has been raised beforehand in the individual step), which can however also be used as its own individual step.The resulting state is again shown schematically and abstractly in FIG. 11, now with the clamp 31 closed and the single step component 36 acting as a holder.In the fifth individual step, the conveyor belt 37, which also forms an individual step component, is then also positioned relative to the splicing device 7, the termination likewise being communicated by a corresponding ready signal. The corresponding time is logged as the end time of the fifth single step in step S 9. The result is shown schematically in FIG. 12.In the sixth individual step, beginning with the ready signal of the conveyor belt 37, the material 32 is then finally pulled back by the scissors 3 via the individual step component 36 and the conveyor belt 37, for example by the tongs 31 being moved accordingly by means of a cross member. The completion of this single step is also communicated as a control signal and serves in particular as a trigger signal for the cutting by means of scissors 3. The trigger signal is stored in step S 10 as the end time of the sixth individual step.After cutting and removal, the clamp 31 can be moved back into the position shown in FIG. 7, which is indicated by the corresponding start signal or ready signal in step S 4 at the beginning of a new cycle.In a step S 11, it is then checked whether there are sufficient information for the evaluation, wherein an evaluation can in principle also already take place during a cycle and does not necessarily have to be waited until the cycle is concluded.In respective steps S 12, the evaluation of the cycle times thus recorded for the various production components is then carried out by the monitoring unit 24, optionally together with at least one production value, by the action conditions. In this case, a step S 12 can respectively process the action conditions assigned to a production component to be monitored. The statements already made above regarding the hierarchical structure of the evaluation and the possibility also of taking into account cycle times of different production components in individual action conditions apply.In a step S 13, the measures of the fulfilled measure conditions, if present, are then carried out by the measure unit 25. For example, warning signals are output and / or operating parameters of the production process are adapted.In step S 14, an output is carried out at the display device 20, where cycle times and associated information can also be output within a user interface. An exemplary representation 38 of a user interface 39 is schematically shown in FIG. 14. Elements less relevant to the procedure described here, such as a status bar 40 and a menu 41, will not be discussed in more detail.For a selected cycle time, for example a cycle time associated with a single step or a total cycle time of a production component to be monitored, the numbers 42 and bar diagrams 43 are displayed in the upper region of the illustration 38 from top to bottom:the lower limit value, learned in the present case, for the cycle time,the most recently detected, currently present cycle time, andthe upper limit value, which is learned in the present case, for the cycle time.It is easily apparent to the operator that the current cycle time is between the lower and upper limit values as desired. It can be represented green, for example.In the lower region of the illustration 38, a table 44 is shown which reproduces cycle times already recorded from previous cycles and / or production processes of the same recipe for further information, for example together with further information such as detection times and the like.Returning to FIG. 6, it is checked in a step S 15 whether the manufacturing process is complete or whether still further cycles follow. If there are still further cycles, the system returns to step blocks 28. However, if the manufacturing process has ended, in step S 16 further evaluations of the captured cycle times with regard to the optimization of manufacturing processes with the recipe and / or predictive maintenance operations to be scheduled can be carried out by means of the evaluation unit 26, as described. In principle, it is of course also conceivable to carry out such evaluation processes already during a production process, since it is then possible, for example, to directly observe the effects of adapted operating parameters on the cycle times and the production values, for example during the optimization, and to carry out, for example, optimization processes by varying operating parameters.References included in the specificationThis list of documents cited by the applicant has been produced in an automated manner and is only included for the better information of the reader.
