- these are usually fixed, fixed settings that can be changed, but such a change is carried out by the operating personnel.
- a second possibility is to change the timing of the light barriers used in the system or in the module, which are used to detect the presence of a processed material.
- By adjusting the timing of the request behavior and the deceleration behavior of the clocked handling stations for the transport of goods is controlled.
- This adaptation allows a shortening or lengthening of the clock cycles, but there is no change in the actual transport speed. Nevertheless, a kind of controlled speed of the overall system results as a result of the changed clock cycle values.

- the re-execution of the same job is improved since the parameters already obtained during operation (which are substantially optimal at the time of the last execution of the job) are now available. Based on these existing parameters, the system can now be set to re-execute the job.
- the ideal speeds and ideal clocks determined in a job are logged and made available again as parameters for each individual component when the stored job is recalled, with a corresponding independent regulation occurring during operation for another composition of the job.
- the advantage of this procedure is that the system can be put into an initial state for processing the job, which is known to work with the equipment already planned for the planned good with the parameters already determined with a high degree of effectiveness.
- a further embodiment consists in the selection of the most suitable system for processing a particular job due to the determined and controlled parameters for adjusting the speed and the clock.
- this adaptation can also be logged in the central operating system and used for further analyzes and can therefore be monitored.

- This job description the paper-handling installation is provided for example in the form of a file electronically, either by (J- transmission over a network or read the file from a disk.
- FIGS. 1 to 3 preferred embodiments of the method according to the invention are explained in more detail below.
- Fig. 1 shows a flow chart showing a preferred embodiment of the method according to the invention.
- the process starts at step S100, in which, starting from an initial state, a processing of goods takes place in a paper handling installation.
- the paper handling system has been set based on a job description, wherein the job description also results in a predetermined number of goods to be processed during a predetermined time interval or during a predetermined period of time. After setting the paper handling equipment and after providing the goods to be merged at the various inlets of the plant it starts to process the job.
- the method according to the invention is provided in order to control the processing of the goods in such a way that a maximum possible number of goods processed during a predetermined period of time occurs (maximum throughput).
- step S102 during the predetermined time period, for example, during a specified time unit of several minutes or several hours, the number of goods processed during that period is detected.
- step S104 it is determined whether the actually processed number of goods is greater than or equal to the predetermined number of goods. If it is determined that the number of goods exceeds the predetermined number, the process goes to step S106 (see FIG. 1B). In this step, the speed at which goods are processed in at least a portion of the paper handling equipment is increased by a predetermined amount of increase, and in step S108, the previously detected new number is set equal to the predetermined number, and now The set parameter and the set speed are stored in step SI10 for later use.
- the plant operates reliably with the current settings, so that according to the invention the processing speed is increased, as will be described in detail below, monitoring whether the increase of the processing speed leads to an increase of the throughput.
- the system is thus regulated in order to achieve the highest possible throughput (number of processed goods per given period of time).
- step S112 see Fig. IC
- step S114 the process ends at step S114. If the job is not fully processed yet, the process returns to step S102.
- step S104 If it is determined in step S104 that the number of goods processed within the time period is lower than the expected number (with or without previous increase), the process goes to step S116.
- the decreasing number of goods compared to the predetermined number is due to the fact that an error has occurred in one or more places during the processing of the goods in the paper handling installation, which as a rule leads to a temporary halt (interruption of processing) of the installation the error has been corrected, for example by the intervention of an operator.
- the number of processed goods is reduced if groups of goods assembled in the system are faulty, for example, if false inserts or a faulty number of inserts have been attached to a cover letter. In this case, these faulty goods are removed from the plant, which is accompanied by a corresponding reduction in throughput.
- everything is regarded as an error, which leads to a reduction in the throughput of processed goods, ie, for example, an interruption of the processing or the generation of defective goods.
- step S116 it is checked in step S116 at which point of the paper handling equipment during the considered period of time an error has occurred.
- at least one state or value of an adjustment parameter hour or a good parameter which was present during the occurrence of the error and which as a rule is the cause of the occurrence of the error is then determined in step S118.
- a mechanical component may have shifted within the system, so that a readjustment is required, or the properties of the material to be processed have changed. This can either be taken alone or together have led to the occurrence of the error.
- step S120 depending on which system parameters and / or good parameters were present at the time of the occurrence of the error, an adjustment of at least one system parameter within a section of the paper handling system is carried out. Additionally or alternatively thereto, the speed at which the goods are processed in the corresponding section of the paper handling system can also be lowered by a predetermined reduction amount, as also shown in step S120. If it is determined, for example, that the system parameters or the material parameters have not changed in the presence of the error compared with previous parameters / good parameters, then it can be assumed that the transport speed has led to the occurrence of the error and in this case it is lowered. As mentioned, this can be done either alone or together with a setting of other parameters of the plant.
- a property of the material parameter to be processed changes, for example the roughness of the paper
- a change in the transport speed is additionally required. Has z.
- the setting of the speed within the system is done for example by changing a speed of a motor, by changing a good acceleration in the paper handling system and / or by changing the clock power.
- the change takes place stepwise or incrementally (incrementally).
- step S120 After the plant has been reset in step S120, the process goes to step 112 in Fig. IC, where it is checked if the job has been finished. If this is not the case, as mentioned above, the method returns to step S102.
- the set parameters are saved, which also gives the possibility to create a protocol with regard to the settings during the processing of the job.
- the settings stored in step S110 can furthermore be assigned to the job file so that they can be used for the initial setting of the installation when the job is executed again, so that the installation automatically responds to the job at a later time when processing a corresponding job corresponding values can be set, which, for example, by the control of corresponding servomotors, which cause the change of the transport elements done.
- the stored data record is first loaded and a causes initial adjustment of the paper handling system, which then according to the invention a readjustment is performed, depending on the current state of the system, current environmental parameters and taking into account possible fluctuations in the properties of the processed material.
- a readjustment is performed, depending on the current state of the system, current environmental parameters and taking into account possible fluctuations in the properties of the processed material.
- this makes it possible to quickly, initially set the paper handling system to jobs that have already been processed once or several times, and at the same time automatically regulate / adjust the system in order to compensate for any differences in the material to be processed or changes in the system and environmental parameters compared to the initial parameters ,
- a control of the processing speed within the paper handling system is carried out, generally, as long as no errors occur, an increase in the processing speed is performed in order to achieve optimum throughput through the system.
- the speed is set such that the speed does not exceed or falls below a predetermined maximum speed or a predetermined minimum speed.
- a "window" is specified for the plant or for components or modules of the plant, which specifies the upper or lower limit of the possible speeds, for example, consider a merger which receives two sheets in parallel and thus promotes them along a stretch, Along this route, with some types of serge, the blades are moved without propulsion, so that a predetermined speed of the blades must not be undercut when feeding to the track to ensure that the leaves reach the end of the line, as well as an upper limit which, if exceeded, will result in damage to the leaves, both the upper limit and the lower limit are lost other of the paper or its properties (parameters, see above).
- FIGS. 2 and 3 Two further preferred embodiments of the present invention are explained below with reference to FIGS. 2 and 3, which introduce threshold values with regard to the deviations of the parameters or with regard to the number of errors occurring during a time interval, depending on which one determines the changes are so serious that plant settings should be changed, or if these changes are within acceptable tolerances.
- a deviation of the detected parameters from those parameters which were detected in a preceding interval or during a preceding time duration is determined in step S130. certainly. This deviation is compared with a predetermined threshold in step S132. When the threshold is exceeded, the setting of the system parameter or the lowering of the speed takes place in step S134. If the threshold is not exceeded, the setting of the paper handling equipment is kept unchanged (see step S136).
- a number of errors occurring during the time period or during the time interval is detected in step S140, and a deviation of the number of detected errors from a previous time duration or time is determined in step S142 detected over a previous interval.
- the deviation is compared with a predetermined threshold in step S144, and if the threshold is exceeded, a change in the setting of a plant parameter and / or a lowering of the velocity follows in step S146. Will the threshold Ie not exceeded, the setting of the plant is maintained (see step S136).
- the system parameters or good parameters prevailing during the time of a fault are taken into account.
- one or more of the environmental parameters described above may additionally be taken into account.
- the wear of individual elements in the paper handling system can additionally be taken into account.
- the environmental parameters or wear parameters just mentioned are either continuously monitored, at a time during the time interval under consideration or once during a plurality of time intervals.
- the system is preferably accessed by accessing a look-up table in which corresponding optimal system parameters are stored for different environmental parameters or for different signs of wear, so that e.g. Depending on an ambient temperature, the system can be switched from an initial temperature range with a first setting to a second temperature range with a second setting of the system parameters.
- an interruption of the job processing for a replacement of the component having the wear is expedient or not. This is determined depending on a possible throughput of the paper handling equipment for the job. For example, a situation may arise in which there is a possibility, despite the detected wear of a component continue to operate the system, but at a reduced speed. In this case, it is decided whether the reduced speed job is processed faster than it is when the tool stops, the worn member is replaced, and the unit is run again at full speed. As an example, consider a wear of a tailor, where the replacement of a knife would take two hours.
- a replacement of the wear member is postponed to a rest period after completion of the job so as to allow the job being processed - only to finish processing.
- a look-up table is accessed, from which the time required for the replacement of an element can be derived, so that the method according to the invention, based on the job description from which the number of goods to be processed in the overall job is known, determines whether the job is interrupted or should be completed at a reduced speed.
- the operating staff is also taken into account.
- the operators of the plant are equipped with transponders to detect the number of operators and their position. This makes it possible to set a utilization of the paper handling equipment depending on the number of operators. If the number of operators is not sufficient, for example, to regularly load the supplements with supplements or regularly remove the finished goods from the output tape, this leads to an interruption (a stop) of the system (error), which in turn leads to a decrease in throughput leads. By monitoring the number of operators, it is determined whether there are enough people to allow continuous operation at full load or not. If the number of operating If the number of persons is insufficient, the processing speed will be correspondingly reduced, which however leads to an increased throughput due to the non-occurring interruptions due to the idling of supplements or the full execution of the subscription band.
- the number of operators it can also be monitored in this embodiment whether errors have occurred during operation without the set parameters having changed in successive time intervals. Together with the information on the number of operators and the position of the operators, it can be detected that errors occur here at plant sections that require an intervention of an operator, so that it can be determined that a reduction of the system speed for proper handling the operator is required. Upon detection that the number of operators is increased, then the speed can be increased again.
- the approach according to the invention also makes it possible to detect an activity of the operator from his movement, for example to communicate that a frequently occurring interruption is not a system error, but because the operator did not add sufficiently quickly enough further equipment or finished processed goods removed from the output tape.
- the goods in the paper handling installation are processed either individually or in groups, with the latter also comprising the total number of goods in a group in the latter case.
- each group comprises the same number of goods, but depending on the job description, different groups will contain different amounts of goods.
- the duration of the composition of the group is different until its output. If, for example, only groups with five elements (cover letter, inserts, etc.) are processed in the time interval, the throughput is higher than if groups with ten elements are processed in the same time interval.
- This situation is taken into account by providing values for the groups indicating the average period of time for generating the groups, such that the "predetermined number" of goods processed during a time interval (here groups) used for the inventive control is based on these Values is determined.
- the paper handling system for the processing of the upcoming job is initially set.
- this is the job description (see above), which describes the initial setting of the system parameters for the job to be processed.
- the system is then set (configured) according to the system parameters received.
- an environmental parameter (see above) may also be captured so that the set paper handling equipment can be readjusted based on this sensed environmental parameter.
- a wear and tear of the paper handling system can be detected, which makes sense if the system has executed / processed one or more other jobs since the last time the job was performed, possibly resulting in wear of individual parts.
- the readjustment of the paper handling system based on the recorded wear occurs.
- the environmental parameters and / or the wear phenomena are carried out so as to allow independent of the throughput, a response to this changed parameter by the Paper handling system, based on the captured parameter values.
- the system parameters and the material parameters can also be continuously monitored during operation so as to automatically carry out a readjustment of the system in case of deviations, whereby here, as mentioned, the parameters are detected either continuously or at specific times during one or more intervals.
- a paper handling system which has several sections, such as a feeder, a collection station, an inserter, etc., as will be described in detail below with reference to FIG. 4.
- the present method is also applied to paper handling systems which have a modular design, wherein, depending on the circumstances detected, either the speed is set in one of the modules or in several of the modules.

- the operators 160A, 160B are further shown, each equipped with a transponder T.
- the control unit 148 communicates with the transponders T to detect the number of operators 160A, 160B and their position. Depending on the number of operators 160A, 160B, the control unit 148 may adjust the utilization of the paper handling equipment 100, as described above.
- the system shown in Fig. 4 operates in the manner described above such that the corresponding sensor signals are output to the central controller 148 via the above-described sensors Si, S 2 .
- the central controller 148 obtains, as described, a job description for the job to be processed. Based on the information stored in this job in conjunction with the recorded personal information
- the central controller 148 reverts to set parameters regarding the set velocities that have already been detected in previous runs, and causes due to the detected Sensor signals a suitable readjustment for the process now to be performed.
- An example of the detection of properties of the material to be processed is the detection of a provided on the paper web code, which is detected in the input channels 102, 104 and 106 by a reading device.
- Such reading devices are designed, for example, to read the code from the paper web while it is being guided past the reading head at, for example, 5 m / s.
- the read head is able to capture the code correctly at this speed.
- situations may arise in which the code on the paper web is poorly readable, whether it is partially masked by other features or imprints due to a malfunction in the previous processing operation, that too little toner has been applied, or that there is little contrast exist. In this case, read errors are recognized because now at the stated speed no read operation is possible.
- An increase in read errors indicates a poorly printed code, so that when a certain threshold of the number of read errors is reached, the system is effective in lowering the "reading speed", that is, the speed of the paper web with which the code on the read head For example, the speed may be lowered to 3 m / s, either in one step or step by step, until the read error rate is below the said threshold is.
- the threshold is undershot, signaling may be generated to generate a message indicating that the code is poorly readable.
- the system is a so-called online system, ie the papers to be processed are generated directly by an upstream high-speed printer, optionally a return channel between the system shown in Fig. 4 and the associated online printers can be made to these in the event of detection to drive a badly printed code to improve the pressure of the code.
- code recognition has been described in the context of input channels 102, 104 and 106, this embodiment may also be used at any other location within the system where a code is detected.
- a warning message is issued to the operator, so that he may initiate steps to counteract this tendency with regard to the badly printed code. If the quality of the code continues to deteriorate or if the code can still not be read due to the speed being reduced, an error message is output after the reaching of a further threshold and the processing is stopped.
- the system includes multiple sheet feeders and it is determined that the errors are due to a feeder being emptied.
- the arrangement shown in Fig. 4 comprises three feeders 142a, 142b, wherein, for example, a first application subtracts sheets from all the sheet feeders. hereby The individual sheet feeder are emptied relatively evenly, so that refilling is possible without problems as a rule.
- a contract driven in which only one of the sheet feeder is used, it is relatively quickly emptied, so that an operator may not comply with the refill, which is noticeable by an increased number of interruptions.
- the equipment can now be automatically configured to lower the processing speed and / or provide the operator with an alternate mode of operation, such as toggle operation, using two of the sheet feeders, from which alternate drawers are withdrawn, leaving enough time for an operator to refill of investments.
- FIG. 5 is a block diagram illustrating the communication of information between the central controller 148 and the individual stations of a paper processing system, such as shown in FIG. 4.
- the individual blocks in FIG. 5 are hereby assigned the corresponding reference symbols of the modules shown in FIG. 4, and the filled horizontal arrows indicate the communication along the system in the "handshake mode", and the unfilled vertical arrows show the Status and situation messages exchanged between the central control 148 and the individual modules for active control.
- system control or system control 148 contains preset manipulated variables for the individual For example, modules that initially set engine speed and the clock cycle of individual modules to provide a defined starting point for processing a job.
- manipulated variables which are set by an operator, for example, optimal operating points determined in previous passes can be read from a memory in order to set the overall system in accordance with the known parameters.
- the required setting can be derived based on information from a job programming or from corresponding specifications of a job.
- the four processing channels shown in Fig. 5 comprise the so-called feed channel 160, the processing channel 162, the finishing channel 164 and the postprocessing channel 166.
- the corresponding channels are the corresponding modules 4, and so-called autoloaders, dispensers and printers are assigned to the feeder channel in addition to the cutters 102, 104, 106 and sheet feeder 142a and 142b shown in FIG.
- the processing channel 162, in addition to the collecting stations 116, 126, 128, 132, 136 shown in Fig. 4, the folding units 118, 122, 134 shown in Fig. 4, and deflectors 124 and 136 shown in Fig. 4, are also rotating devices, staplers, and the like assigned.
- the end processing channel 164 is assigned, in addition to the inserter 144 shown in FIG. 4, stackers and sorters and similar elements.
- the post-processing channel in addition to the tray 146 shown in FIG. 4, franking devices, printers, reader devices, sorting devices, packaging devices and the like are also assigned.
- a paper handling system according to the present invention is described with reference to a modular inserting system, it should be noted at this point that the device according to the invention is not limited to modular systems.
- the approach of the present invention may be applied to a non-modular paper handling equipment having one or more paper handling stations.
- the approach according to the invention can also be used only in conjunction with the inserter 144 shown in FIG. 4, or with a subset of the modules shown, in which case the inserter 144 merely receives, envelopes and outputs the items to be dumped.
- the paper handling system according to the invention is not limited to the inserting machine shown in FIG. 4.
- the system according to the invention can also be used for other systems of a different configuration, such systems then being able to have additional auto loaders, unwinders, printers, turning devices, staplers, sorters, franking machines, packaging devices, etc.
- the exemplary embodiment described with reference to FIG. 4 has sensors on the above-indicated elements of the corresponding channels, but depending on the circumstances of the system either less than all individual modules or only selected individual modules as the individual modules described above, the required sensors can be provided.
- the method according to the invention can be applied to an entire system, to parts of a system or to individual modules of a modular system, the individual sections or modules of the entire system being controlled by a central controller.
- individual selected sections or modules that are particularly critical to the processing of the goods are monitored and their speed is controlled but may also be controlled be provided to monitor and control each individual section or each module.
- the present invention is not described in the above-described exemplary embodiments, but is used everywhere where mechanically paper within a
- Storage and / or further processing device is supplied, and thus generally relates to all semi and fully automatic paper processing systems.
- modules immediately downstream or downstream of the processing stream refuse to accept the goods for processing because the goods are e.g. too fast (for example, a factory can only accept goods, such as paper, at maximum speed to ensure proper folding). In this case (event), the goods are no longer deducted from the precursor component, so that the throughput is reduced without a "classic error" occurring.
- the throughput can - without the occurrence of a "classic error" - reduce, for example, if the goods to be driven too far away from each other. If the problem of congestion or the like arises if the distance is too short, which leads to a stop of the system and thus reduces the throughput, then a reduction is also given if the distance of the goods is too great.
- the approach according to the invention will take effect and lead to a control of the plant or plant parts (or modules) in order to adapt the speeds during processing, to increase or decrease the distance, etc.
- the setting of the speed of processing has been explained primarily by means of setting the motors which carry the goods.
- the present invention is not limited thereto.
- the times at which a successor component requests a good from a precursor component are changed (increased / decreased) to influence the processing speed.
- the distance of the goods may be changed (increased / decreased) to affect the processing speed.
- the system is already running in normal operation.
- job processing is restarted, the job will either be repeated or run for the first time. If the job to as ⁇ derholten times executed, the initial value for the desired flow rate with the job can be stored and the plant can be provided.
- an initial value may be missing for the desired throughput (especially if the job is being run for the first time).
- the initial value for the desired throughput is provided either by the job, set by an operator, or set to a predetermined value (eg, zero).
