WAYS OF EMBODYING THE INVENTION

(7) In FIGS. 1 to 5, the reference sign 100 refers to a computer-controlled printed product processing system comprising a collecting system 1. The collecting system 1 comprises at least one conveyor 11 and a plurality of feed conveyors 13 which feed respectively different products 3 to the conveyor 11 depending on their product occupancy. Depending on the application, a plurality of feed conveyors 13 are occupied by the same product (split operation), for example in the case of thick products, where the manual equipping of an individual feed conveyor 13 is too slow to cover the uninterrupted feeding of products 3 to the conveyor 11 by a single feed conveyor 13.

(8) FIGS. 1 to 5 illustrate just four feeding feed conveyors 131, 132, 133, 134 for simplification; in one practical embodiment, the collecting system 1 of the printed product processing system 100 comprises a much greater multiplicity of feed conveyors 13, for example several dozen or more than one hundred. In different embodiment variants, the collecting system 1 is designed to create, by collating, inserting or collecting products or by other product-combining operations, combinations of products, which we designate here as product collections, and correspondingly comprises a conveyor 11 having a circulating collating section, a collecting drum, a belt conveyor for collating imbricated streams, or a collecting section, in each case with or without a collection carrier, for example grippers.

(9) The example of the collecting system 1 illustrated in FIGS. 1-5 comprises a conveyor 11 having a plurality of serially arranged collection carriers 12, for example grippers, which are guided along a closed line cyclically past the feed conveyors 13 and take up the products 3 fed. As a result of the sequential feeding of the products 3, a product collection 4 is compiled on the conveyor 11, in particular on or respectively in the collection carriers 12.

(10) The printed product processing system 100 additionally comprises at least one reject diverter 14, which feeds faulty product collections 4* away from the conveyor 11 to a reject removal system 15. Faulty product collections 4* are detected by various sensors (not illustrated) in the printed product processing system 100.

(11) The reference sign 16 designates a controllable transfer unit, which feeds the completely compiled product collections 4 via a further conveyor 17, for example a chain conveyor with grippers, to a stacking station 5, which creates a pack 40 having a defined number of product collections 4 and feeds it to an outgoing conveyor 18, for example a belt conveyor, in order to be transported away.

(12) As is illustrated schematically in FIGS. 1-5, the printed product processing system 100 comprises in different embodiment variants in addition to the stacking station 5 one or a plurality of further processing systems 19 disposed downstream of the transfer unit 16, for example. Such further processing systems 19 comprise, for example, a packaging system, e.g. a film wrapping system, a system for inserting additional products or product collections 4 into a main product, a system for stitching and/or cutting, a system for bonding and/or cutting, and a system for imprinting or sticking on additional information such as, for example, name and address. Depending on the embodiment variant and system configuration, a plurality of stacking stations 5, 5 are connected to the collecting system 1.

(13) Depending on the embodiment variant and production situation, the conveyor 17 feeds excess product collections 4 to a discharge station 6.

(14) Depending on the embodiment variant and production control, the controllable transfer unit 16 guides incompletely compiled collections 4 on the conveyor 11 for completion of the incomplete collection 4 on an additional further cycle on the conveyor 11 past the feeding feed conveyors 13.

(15) For counting products 3 fed, faulty product collections 4*, complete and excess product collections 4, and/or created packs 40, the printed product processing system 100 additionally comprises various counters (not illustrated).

(16) The person skilled in the art will understand that the printed product processing system 100 illustrated in FIGS. 1 to 5 can comprise in further embodiment variants or respectively system configurations further components and/or other arrangements, for example a further controllable transfer unit 16 and/or a different design of the conveyor 17, which enable separation and/or slowed-down conveyance for manual completion of an incomplete collection 4 with missing products 3.

(17) For control purposes, the printed product processing system 100 comprises a control computer 10, which is connected to the various components and units of the printed product processing system 100 via communication connections, in particular to the conveyor 11 of the collecting system 1, the feeding feed conveyors 13, the reject diverter 14, the controllable transfer unit 16, the further processing system 19, the stacking stations 15, 15, the different further conveyors 17, 18 and the sensors and counters mentioned.

(18) The control computer 10 is designed to track (tracking information) the product collections 4 conveyed on the conveyor 11 or respectively the incomplete collections 4 with regard to their positions on the conveyor 11, their content and structure (i.e. products and order), the envisaged and/or changed collection type (with specific collection structure), and/or the number of cycles run through on the conveyor 11. To create individualized product collections 4 provided, for example, with an individual address of a recipient and/or in terms of content with content and thus structure of the product collection geared individually to the relevant recipient, a product collection 4 can be identified and tracked over its entire creation time from the first feeding feed conveyor 13 on the conveyor 11 until stacking on a specific pack 40 in the printed product processing system 100.

(19) The reference sign 2 refers to a computerized control device embodied as part of the control computer 10 or on a separate computer. As is illustrated schematically in FIGS. 1 to 5, the control device 2 comprises various function modules, in particular a system configurator (system configuration module) 21, a production configurator (production configuration module) 22 and a strategy selector (strategy selection module) 23, and data memory or respectively program memory for storing system configuration parameters 24, production configuration parameters 25 and production strategies 26. The function modules are preferably embodied as programmed software modules which comprise computer program code for controlling one or a plurality of processors of one or a plurality of computers. The computer program code is stored on one or a plurality of (tangible) computer-readable storage media connected to the processors fixedly or removably. The person skilled in the art will understand, however, that the function modules in alternative embodiment variants can be embodied in part or completely by hardware components.

(20) The control device 2 and/or the control computer 10 are/is preferably connected to a superordinate computerized supervisory control system (not illustrated).

(21) The system configurator 21 is designed to detect and to store system configuration parameters 24 which define the configuration of the printed product processing system 100.

(22) The system configuration parameters 24 comprise, for example, indications about the number, the type and/or the function of the feed conveyors 3, the position of the feed conveyors 3 on the conveyor 11, e.g. a sequential position number, the number and, if appropriate, type of the collection carriers 12 of the conveyor 11, the number and the type of operationally available and/or connectable stacking stations 5, 5, the position of the connectable stacking stations 5, 5 with respect to the conveyor 17, the number of reject diverters 14, the position of the reject diverters 14, the number and type (function) of the further processing systems 19 and/or the position of the further processing systems 19.

(23) The system configurator 21 preferably comprises a (for example graphical) user interface with display and operating elements for inputting the system configuration parameters 24, for example during the installation of the printed product processing system 100, during preparation for the production and/or during the production. System configuration parameters 24 which are input during the production are therefore run time data which determine the dynamic selection of a production strategy 26. That is to say that by inputting the above-described system configuration parameters 24 by addition, amendment and/or erasure, it is possible to influence the selection of the production strategy 26 during the production time.

(24) In one variant, the system configurator 21 is additionally designed to detect and to store at least certain system configuration parameters 24 automatically by interrogation via a communication channel from the different components of the printed product processing system 100, on the one hand static but on the other hand also run-time-dependent system configuration parameters 24 of the printed product processing system 100, whereby the system configuration is automatically updated at the production time in particular also with regard to available or respectively failing system components. The dynamic detection of run-time-dependent system configuration parameters 24 is effected, for example, periodically and/or upon enquiry or respectively user instruction.

(25) The production configurator 22 is designed to detect and to store production configuration parameters 25 which define at least one production series for compiling product collections 4 composed of a plurality of products 3 fed. In this case, a production series is a production run for compiling product collections 4 having a specific collection type, i.e. a specific collection structure, wherein a production run has a production start and a production end and can comprise a plurality of different production series. Alongside information for creating product collections 4 and packs 40, the production configuration parameters 25 also comprise, in particular, customer-specific indications (specifications) concerning product quality or respectively permissible fault tolerance in the production and concerning the delivery of the packs 40 or respectively product collections 4.

(26) In one variant, at least certain production configuration parameters from among the production configuration parameters 25 are communicated to the product configurator 22 by the superordinate supervisory control system.

(27) The production configuration parameters 25 comprise, for example, indications about the structure of a product collection 4, that is to say the number and, if appropriate, the prescribed order of products 3 in a product collection 4, the size of a product collection 4, the number of product collections 4 in a production or respectively production series, route information for the efficient delivery of packs 40 with product collections, address information for the delivery of packs 40 or respectively product collections 4, the number of empty positions, for example empty collection carriers 12, between two production series succeeding one another in a production run for creating different product collections 4, the occupancy of the feed conveyors 13, that is to say the order and number of products 3 of a specific product type on a relevant feed conveyor 13, and/or the split operation of two or more feed conveyors 13 with occupancy by the same products 3.

(28) The route information or respectively address information for the delivery of packs 40 with product collections 4 comprises an assignment of packs 40 to defined delivery sequences or geographical positions, for example an assignment of packs 40 with product collections 4 of a specific collection structure to specific routes, addresses or zones. In one embodiment variant, the route information or respectively address information for the delivery of packs 40 additionally comprises assigned weather indications which, for specific geographical areas, enable an automatic weather-dependent route selection or respectively address selection at the production time.

(29) Depending on the embodiment variant, the production configuration parameters 25 comprise, moreover, indications about the number of product collections 4 in additional production for a production or respectively a production series, that is to say the planned number of additional (redundant) product collections 4 above the defined desired production, the tolerance of incorrect withdrawals per product 3 overall and/or for each feed conveyor 13, the tolerance of pack faults, the tolerance of collection faults, e.g. the tolerance of faults of the product series or additional products 3 in a product collection 4, the conditions with regard to production volume or respectively production speed, the treatment of excess product collections 4 produced, and/or the tolerance with regard to route conformity of packs and/or the order of packs.

(30) The production configurator 22 preferably comprises a (for example graphical) user interface with display and operating elements for inputting the production configuration parameters 25, for example during preparation for the production and/or during the production. Production configuration parameters 25 which are input during the production are therefore run time data which determine the dynamic selection of a production strategy 26. That is to say that by inputting (adding, amending and/or erasing) the above-described production configuration parameters 25 or other production configuration parameters, such as, for example, current weather indications for specific geographical areas, it is possible to influence the selection of the production strategy 26 during the production time, for example the selection of the routes or respectively addresses for the delivery of the packs 40, 40a, 40b with product collections and thus the suitable creation of the packs 40, 40a, 40b and their order or respectively arrangement for an efficient route-specific delivery. In one variant, even the order of the product collections 4, 4a, 4b in the packs 40, 40a, 40b is determined for an efficient route-specific delivery. By way of example, for the production of the packs or respectively product collections the delivery route selected in the case of sunny weather may be different from that selected in the case of rainy weather.

(31) The production strategies 26 in each case comprise executable and/or interpretable instructions and/or control parameters for controlling the printed product processing system 100 in the case of specific situations, states and events during the production or respectively a production series, that is to say depending on a wide variety of run time data such as production configuration parameters 25 input during the production time, system configuration parameters 24 or weather data, or fault-indicating run time data such as system faults or production faults.

(32) The production strategies 26 comprise, in particular, stored instructions and/or control parameters for controlling components of the printed product processing system 100, for example for controlling the conveyor 11, individual feed conveyors 131, 132, 133, 134, the reject diverter 14, the controllable transfer unit 16, the further processing system 19, the conveyors 17, 18 and/or the stacking stations 5, 5 in the case of defined run-time-specific scenarios, constellations, configurations and events, in particular upon the occurrence of defined fault situations and fault states when compiling a product collection 4 or respectively feeding a product 3 to a product collection 4.

(33) Preferably, the selected production strategies 26 for controlling the printed product processing system 100 are executed on the control computer 10 or are respectively interpreted by the control computer 10 or their control parameters are evaluated on the control computer 10. The person skilled in the art will understand, however, that in alternative embodiment variants at least certain instructions and/or control parameters of the selected production strategies 26 can be executed, interpreted or evaluated in distributed fashion by processors of other computerized components of the printed product processing system 100.

(34) In one embodiment variant, a respective strategy assessment assigned to the defined production strategies 26, as illustrated in table 1, is stored, for example a strategy priority value P.sub.1, P.sub.n, an expected rejects value A.sub.1, A.sub.n and/or an expected performance value L.sub.1, L.sub.n.

(35) The strategy priority value P.sub.1, P.sub.n is, for example, an index or measure of the degree to which the assigned production strategy PS.sub.1, PS.sub.n is generally preferred or respectively subordinated relative to other production strategies PS.sub.1, PS.sub.n.

(36) The expected rejects value A.sub.1, A.sub.n is an index or measure of the degree to which the assigned production strategy PS.sub.1, PS.sub.n is geared to feeding faulty product collections 4*, in particular incomplete collections 4 with failed product feeding, via the reject diverter 14 to the reject removal system 15, or conversely the degree to which the assigned production strategy PS.sub.1, PS.sub.n is geared to correcting incomplete collections 4 with failed product feeding by conversion into a different collection type and/or completion by return via the controllable transfer unit 16.

(37) The expected performance value L.sub.1, L.sub.n is an index or measure of the degree to which the assigned production strategy PS.sub.1, PS.sub.n is geared to keeping the production times (production duration) as short as possible or respectively the production throughput and the production speed as high as possible, by treating faulty collections 4*, in particular incomplete collections 4 with failed product feeding, as far as possible without additional production steps, in particular without empty production cycles.

(38) The strategy priority value P.sub.1, P.sub.n, the expected rejects value A.sub.1, A.sub.n and the expected performance value L.sub.1, L.sub.n are, for example, ranking values from a defined ranking scale having a range of values between a lowest rank, e.g. one, and a highest rank, e.g. ten. Corresponding (e.g. user-specified) indications in the production configuration parameters with regard to preferred strategy assessments, in particular with regard to strategy priority values, rejects values and/or performance values, enable a selection in this regard of the production strategies 26 by the strategy selector 23.

(40) In one embodiment variant, in each case one or a plurality of configuration conditions assigned to the defined production strategies PS.sub.1, PS.sub.n as illustrated in Table 1, were stored. The configuration conditions in each case comprise defined minimum and/or maximum values SK.sub.11min, SK.sub.11max, SP.sub.1qmin, SP.sub.1qmax, SK.sub.n1min, SK.sub.n1max, SP.sub.nqmin, SP.sub.nqmax, for specific system configuration parameters 24 and/or production configuration parameters 25, which have to be correspondingly configured in order that the relevant production strategy PS.sub.1, PS.sub.n can be selected and activated in the relevant production run or respectively in the relevant production series, that is to say that the value of a relevant system configuration parameter 24 or production configuration parameter 25 must have at least the corresponding minimum value SK.sub.11min, SP.sub.1qmin, SK.sub.n1min, SP.sub.nqmin, and/or at most the corresponding maximum value SK.sub.11max, SP.sub.1qmax, SK.sub.n1max, SP.sub.nqmax.

(41) The strategy selector 23 is designed to select and activate one of the stored production strategies 26 on the basis of the (current) stored system configuration parameters 24, the (current) stored production configuration parameters 25 and, if appropriate, the assigned configuration conditions and/or strategy assessments. Depending on the application and situation, the strategy selector 23 can change the production strategies 26 for example from one production series to the other or even within a production series, such that typically two successive production series have different production strategies 26 or even a single production series with a plurality of different production strategies 26 is produced.

(42) In one embodiment variant, the strategy selector 23 is activated when there is a change in specific run time data for the dynamic selection of the production strategy 26, for example in the case of specific user inputs such as current (or forecast) weather data, or in the case of fault-indicating run time data such as production faults or failures of specific system components or other abrupt system configuration changes.

(43) Alongside the function as an evaluation module, in one variant the strategy selector 23 additionally has the function of a monitoring module, that is to say that the strategy selector 23 does not just evaluate defined decision basis data for dynamically determining and activating a situationally optimum production strategy 26, but additionally detects at least certain of the decision basis data in the printed product processing system 100 and/or from the user.

(44) In one embodiment variant, the strategy selector 23, before the selection of the production strategy 26, activates the system configurator 21 for detecting run-time-dependent system configuration parameters 24 of the printed product processing system 100.

(45) In a first step, the strategy selector 23 determines the production strategies 26 which are selectable, by respectively checking whether the assigned configuration conditions of a production strategy PS.sub.1, PS.sub.n are met by the current system or respectively production configuration, that is to say whether the current system configuration parameters 24 and/or production configuration parameters 25 correspond to the defined minimum and/or maximum values SK.sub.11min, SK.sub.11max, SP.sub.1qmin, SP.sub.1qmax, SK.sub.n1min, SK.sub.n1max, SP.sub.nqmin, SP.sub.nqmax of the production strategy PS.sub.1, PS.sub.n. In one variant, production strategies 26 whose configuration conditions are not met by the current system configuration parameters 24 and/or production configuration parameters 25 are automatically deactivated and, for example, reactivated only when their configuration conditions are met.

(46) If a plurality of selectable (or respectively non-deactivated) production strategies 26 are determined, in a second step the strategy selector 23 selects the production strategy 26 to be applied and to be activated, for example on the basis of the assigned strategy assessment of the relevant production strategy PS.sub.1, PS.sub.n, that is to say depending on which production strategy PS.sub.1, PS.sub.n has a high assigned strategy priority value P.sub.1, P.sub.n and/or a rejects value A.sub.1, A.sub.n and/or performance value L.sub.1, L.sub.n which best corresponds to a preferred strategy assessment contained in the production configuration parameters 25, in particular with a preferred rejects value and/or a preferred performance value.

(47) In a further embodiment variant, the strategy selector 23, for the selection of the production strategy 26, additionally takes account of production state values of the current production run or respectively of the current production series such as, for example, the number of fed or respectively remaining products 3 of the feed conveyors 13, the number of faulty or respectively removed collections 4*, the number and position of incomplete collections 4, 4a, 41, the number of complete and excess product collections 4 and/or the number of created packs 40.

(48) The selected production strategy 26 is then applied or respectively implemented for controlling the printed product processing system 100, for example upon the detection of new or respectively changed run time data such as weather data, system faults or production faults, e.g. faults in compiling a product collection 4, in particular upon the detection of an incomplete collection 4 in which one or a plurality of products 3 are erroneously missing at the relevant location in the production or respectively production series.

(49) FIG. 2 illustrates the printed product processing system 100 during the production, wherein product collections 4 of one specific collection type are compiled in one running production series and product collections 4# of a collection type different from the collection type of the running production series are compiled in a subsequent production series.

(50) As is illustrated schematically in FIG. 2, the feed conveyor 131 feeds a first product 41 to the conveyor 11, for example onto a collection carrier 12, for compiling the product collection 4. A respective further product is fed by the subsequent feed conveyors 132, 133, such that a partial collection 42 or respectively 43 is formed on the conveyor 11, for example in the relevant collection carrier 12, said partial collection being completed by the feed conveyor 134 by feeding a further product to the product collection 4. The product collections 4 are transported by the conveyor 17 to the stacking station 5, where they are stacked and the packs 40 created are led away.

(51) On the conveyor 11, the reference sign 4# in FIG. 2 designates a product collection of a collection type which is different from the collection type of the running production series and which was produced in accordance with a selected production strategy 26 on the basis of an incomplete collection (partial collection), which was originally provided for compiling a product collection of the collection type of the running production series, but in the case of which failed product feeding was detected. This dynamic collection conversion strategy is selectable depending on the collection structures of successive production cycles and the occupancy and arrangement of the feed conveyors 13. A further condition for this is that the product collections 4# produced outside the regular order can be stacked by a separate stacking station 5 provided for this purpose, or that the product configuration parameters 25 define a tolerance of pack faults which tolerate product collections 4# having different collection types on a pack 40 of product collections 4. Depending on the feed conveyor 13 at which the product feeding fails, it may additionally be necessary for a tolerance for a deviating product order and/or additional products 3 in a product collection 4# additionally to have been specified for the collection conversion.

(52) If the production strategy 26 is not selectable for a collection conversion, the incomplete collection 4, 41, in alternative production strategies 26 for completion, can be fed to an additional cycle or be removed as a faulty collection 4* by ejection, wherein, in the latter case, depending on the additional production specified, it is necessary to increase the production target for the product collections 4 of the relevant collection type.

(53) Moreover, the two incomplete collections 4, 41 in FIG. 2 schematically illustrate different production strategies 26 for completing incomplete collections. The incomplete collection designated by 41, after the detection of failed product feeding, for example at the feed conveyor 132, without the feeding of further products by the subsequent feed conveyors 133, 134, was transported further on the conveyor 11 in order subsequently to be guided to an additional cycle on the conveyor 11 for completion with the missing products of the feed conveyors 132, 133, 134. This return, with an additional cycle on the conveyor 11, without prior feeding of products after fault detection, is selected, for example, if the product order in the product collection has to be complied with and conversion into a product collection 4# of a different collection type is not possible. By contrast, the incomplete collection designated by 4 in FIG. 2, after the detection of failed product feeding, for example at the feed conveyor 132, was supplemented with further products of the subsequent feed conveyors 133, 134 because in this hypothetical example the product order need not be complied with, and was then guided to an additional cycle for completion, for example by feed conveyor 132.

(54) FIG. 3 illustrates the printed product processing system 100 during the production upon the transition from a first production series for product collections 4a of a first collection type to a subsequent second production series for product collations 4b of a second collection type. As is illustrated schematically in FIG. 3, the transition takes place seamlessly in the example in FIG. 3, for example without empty collection carriers 12 between the different product collections 4a, 4b on the conveyor 11. Depending on the production strategy, however, empty locations, for example empty collection carriers 12, can also be provided between the production series. As is evident in FIG. 3, the product collections 4b of the second collection type are compiled by the feed conveyors 13, as described above with reference to FIG. 2 for the product collections 4, sequentially via partial collections 41b, 42b and 43b, while the already fully compiled product collections 4a of the first collection type are transported by the conveyor 11 to the stacking station 5, where they are stacked to form packs 40a of the first collection type and are led away.

(55) The example in FIG. 3 additionally illustrates how an incomplete collection 4a of the first collection type is guided past the feed conveyors 13 once again on an additional cycle for completion, wherein the corresponding location on the conveyor 17, for example the corresponding collection carrier 12, remains empty (this can also be prevented with a variable advance of the conveyors 17). In the case of this simultaneous compiling of product collections 4a, 4b having different collection types, the incomplete collection 4a will be transported after its completion on the conveyor 11 as product collection of the first collection type in the midst of product collections 4b of the second collection type to the stacking stations 5, 5.

(56) As is illustrated in FIG. 4, the completed product collection 4a of the first collection type is fed by the conveyors 17 to the stacking station 5, which in this phase is provided for example for the (delayed) stacking of the product collections 4a of the first collection type and already contains an incomplete pack 40a of product collections 4a of the first collection type, whereas the stacking station 5 is provided for the running creation of packs 40b having product collections 4b of the second collection type. The production strategy 26 with intermixed collection types on the conveyor 11 is not selectable if a plurality of stacking stations 5, 5 are not available or the packs 40a, 40b are not permitted to have product collections 4a, 4b having different collection types.

(57) If the production strategy 26 with intermixed collection types on the conveyor 11 is not selectable, the production series for producing product collections 4b of the second collection type can be started only when the returned product collection 4a of the first collection type has been completed by the relevant feed conveyor, for example 134, as is illustrated schematically in FIG. 5. This production strategy 26 described above ensures, in the case of a single stacking station 5, homogeneous packs 40a with product collections 4a which uniformly have the first collection type, although to the detriment of the production performance, since in this case, numerous locations, for example collection carriers 12, on the conveyor 11 remain empty, as can be seen in FIG. 5, and the throughput quantity or respectively production speed is correspondingly reduced.

(58) Besides the above-described production strategies 26 for the treatment of faulty collections including further guidance with or without feeding of further products, the maintenance or conversion of the collection type provided, completion with or without an additional cycle on the conveyor 11, ejection of partial collections with or without an increase in the production target, the beginning of a production series during or after the completion of partial collections of preceding production series, depending on the embodiment variant further production strategies 26 for controlling the printed product processing system 100 in the case of new or respectively changed run time data are provided, which are automatically selected and activated by the strategy selector 23 on the basis of the current system configuration parameters 24, the current production configuration parameters 25, the run time data determined and the assigned configuration conditions and/or strategy assessments, for example slowed-down further guidance and/or separation of the faulty collections with or without feeding of further products for the subsequent manual completion with the missing product or products.

(59) It will finally be mentioned that although in the description computer program code was assigned to specific functional modules and the performing of steps was explained in a specific order, the person skilled in the art will understand that the computer program code can be structured differently and the order of at least certain steps can be changed, without in this case departing from the subject matter for which protection is sought.
