Definitions
- the invention relates to an RFID conversion system for the single and/or multi-lane production of RFID products and a control method for controlling inlay dispensing modules of an RFID conversion system.
- RFID technology is used for the contactless transmission of information.
- the relevant information is stored on a passive transponder whose core component is a microchip.
- the microchip is connected to an antenna structure, which is usually attached to a thin plastic film or paper.
- a read/write device emits a radio signal in a specific frequency band. These radio waves induce an electrical voltage in the antenna structure of the passive transponder, which is sufficient to activate the microchip and thus process data.
- RFID transponders are used, for example, in chip cards, tickets, playing cards, tokens, stickers and tags, such as clothing labels and shipping labels, as well as flight luggage tags.
- the antenna with the attached chip is incorporated into multi-layer RFID products using RFID conversion systems. This protects the antenna and the chip and, if necessary, also achieves a corresponding look, feel and robustness for the respective application. A pitch change is also possible in this way, which can be provided in particular for cost reasons and to save material.
- the term "pitch" refers to the distance between adjacent RFID chips.
- RFID conversion systems are used to manufacture ready-made RFID products based on various raw materials. In this case, different end products are produced in the RFID conversion system by laminating different materials, in particular web-like materials or sheet-like materials.
- Both self-adhesive coated materials can be used as well as an adhesive application using a hot melt device directly in the machine.
- bonding with other types of adhesive is also possible.
- reactive adhesives such as the special adhesive sold under the trade name UHU POR or PUR adhesives can be used.
- the RFID products manufactured in an RFID conversion system usually consist of a carrier material, an inlay, ie a thin substrate with antenna and microchip, and, if necessary, a cover material. Special products may have additional intermediate layers. In most cases, the backing material and cover material are in the form of webs.
- the inlay is usually prefabricated as an endless strip and wound up as a roll to form an inlay roll. Such an inlay roll is usually produced outside of the RFID conversion system in an upstream production step in a separate system. These ready-made inlays are used as primary material for further processing on RFID conversion systems.
- RFID conversion systems have a large number of web guiding devices, such as deflection rollers, unwinding and winding.
- web guiding devices such as deflection rollers, unwinding and winding.
- (hot) glue devices punching devices, reading and writing devices, printing devices and optical and electrical inspection devices, as well as longitudinal or cross cutting devices can also be provided.
- RFID conversion systems are available in a single-lane version or in a multi-lane version.
- the production of RFID products in RFID conversion systems usually provides for the separation of an inlay web and the dispensing of the separated inlays on a carrier web.
- the inlays can either be in "dry” form, i.e. non-adhesive, or as “wet inlays", i.e. already equipped with an adhesive layer.
- the inlays are arranged as densely as possible on the inlay sheet, with an inlay pitch being specified.
- the term "inlay pitch" refers to a certain distance between two adjacent inlays in the direction of web transport. In most cases, however, the desired end product has a different division that depends on the product and the product design.
- the inlay web is therefore cut crosswise in a first process step in order to cut off individual inlays or to separate the inlays.
- inlays are then placed individually on the carrier sheet at the appropriate distance.
- the placement can be done in a continuous flow or in an intermittent start-stop process. This makes it possible to laminate and/or further process the arrangement of inlays and carrier web with additional layers.
- Another aspect of the manufacture of RFID products in RFID conversion systems relates to the so-called "good test" of the inlays. Errors can occur both in the microchips and in their contacting with the antenna structures, which means that RFID transponders do not work at all or only to a limited extent. Inlays are therefore frequently checked individually before they are applied to the carrier web and defective inlays are ejected after detection and the gap in the inlay that has arisen as a result of ejection is then closed. The goal is end products with only flawless inlays.
- the inlays are fitted to the carrier web in a central process, with the individual inlays being dispensed in the exact position using a central dispensing unit.
- the inlay web is cut in the dispensing unit, positioned in register on the product pitch and applied. This can be single-lane or multi-lane.
- the web of material on an inlay roll of the dispensing unit reaches its final state, it is necessary to stop the RFID conversion system for the necessary change of the inlay roll. This leads to a significant reduction in production/plant runtime and reduces the efficiency of the plant.
- the roll change can be done manually or automatically with a highly complex splicing device.
- the object of the present invention is to provide an RFID conversion system and a control method of the type mentioned at the outset, the RFID conversion system according to the invention being characterized by longer production and system running times and a high degree of automation.
- easy scalability of the production capacity, easy operability and uninterrupted operation of the system should be ensured when an inlay supply on an inlay dispenser module is exhausted, especially when the end of an inlay roll wound up as roll goods is reached.
- the RFID conversion system according to the invention and the control method according to the invention should also allow faulty inlays to be removed and replaced in a simple manner and in particular without interrupting the operation of the system.
- an RFID conversion system for the single-track and/or multi-track production of RFID products which has a plurality of inlay dispenser modules in place of a central dispenser station or a central dispenser unit, with each dispenser module being designed and set up for direct assembly of a web or sheet-shaped carrier material in particular or for indirect inlay assembly of a means of transport, such as one Vacuum conveyor belts, and the dispensing modules are independently controllable.
- At least two inlay dispenser modules, preferably all inlay dispenser modules, of the RFID conversion system according to the invention can be used as required and independently of one another for direct or indirect assembly and can be operated in different operating modes due to the different controls, in particular as assembly modules, buffer modules or post-dispenser modules or as roll-up modules , for example to wind up a waste web from a neighboring dispenser module.
- several inlay dispenser modules can be operated in different operating modes at the same time, in which case different operating modes can be characterized in particular by different placement rates of the inlay dispenser modules, ie the number of inlays provided per hour, and/or different cycle times.
- an “inlay” within the meaning of the invention relates in particular to a thin substrate material section with an antenna and microchip applied thereto, with the substrate material being able to be present in web or sheet form and a plurality of inlays in a row or in several adjacent rows following an inlay web or an inlay sheet can form.
- An inlay sheet is formed by a strip of substrate material on which antenna structures with installed microchips are applied.
- An inlay sheet can be formed by a sheet-like substrate material section of predetermined length and width, on which one or more rows of antenna structures with installed microchips are arranged.
- the production of the inlays i.e. the assembly of antennas and microchips, is preferably not part of the RFID conversion system and can be carried out in an upstream production step in a separate machine or system.
- the ready-made inlays are used as primary material for further processing on the RFID conversion system according to the invention.
- inlays Due to different antenna geometries and requirements, inlays can have different dimensions and pitches on an inlay track.
- a central function of the RFID conversion system according to the invention can therefore be the separation of the inlay web and the dispensing of individual inlays onto the carrier material. Due to costs, inlays are placed as tightly as possible on an inlay sheet arranged.
- the inlay pitch is therefore predetermined.
- the desired RFID product for example a ticket, a sticker or the like, usually has a different pitch, which depends on the product and its design and is also predetermined.
- an “inlay dispensing module” within the meaning of the present invention is particularly set up and designed to separate inlays that are stored as an inlay web or sheet of inlays, if necessary, and to dispense or apply individual inlays to a carrier material or a means of transport.
- an inlay dispensing module can also be set up and designed to dispense or apply thin material sections made of any flexible material to a web or sheet-shaped carrier material or a means of transport, in particular after a previous cutting process for separating sections of a material web or a material sheet of the flexible material.
- the dispensing modules can also be used in the application in such a way that different inlay types, for example for booster antennas, chip modules and/or HF and/or UHF mixed in one product, can be placed at the individual dispensing positions.
- the invention is not limited to placing identical inlays.
- loading module means "buffer module” and “replenishment module” are explained below using an example.
- the production of the RFID products can take place using at least one, in particular, web-shaped material and/or optionally using at least one further, in particular, web-shaped intermediate material and/or at least one adhesive layer.
- Inlay- Dispensing modules can be used, for example, to dispense a covering material.
- the RFID conversion system can provide for direct assembly, i.e. inlays can be dispensed with at least one inlay dispenser module at the exact position onto a (continuous) carrier web, or assembly can also be carried out on sheets of carrier material with a defined length.
- the carrier material can have one or more layers.
- indirect assembly can be provided by dispensing the inlays onto a transport means, such as a vacuum conveyor belt, with the inlays then being transferred from the transport means to the carrier material or carrier product.
- inlay rolls wound up as roll goods can be used as the primary material, with the inlay webs unwound from the inlay rolls being able to be cut in a first process cut in order to separate individual inlays.
- inlay sheets can be taken from a supply stack or a storage container, for example, and cut to separate the inlays.
- inlay dispenser modules there is the option of storing individual inlays and applying them with the inlay dispenser modules.
- An inlay roll or an inlay sheet forms an inlay supply of the dispensing module, which is used up by the assembly and has to be replenished at regular intervals, for example by changing the roll or refilling an inlay sheet store.
- An inlay dispenser module can preferably have a structure that corresponds to the structure of commercially available label dispensers that are used for labeling products in transit.
- a cutting device can preferably be implemented in an inlay dispensing module in order to separate individual inlays from an inlay web or an inlay sheet.
- the dispensing module can be set up and designed to hold an inlay roll or also to receive and store inlay sheets and have at least one such inlay roll or at least one such inlay sheet.
- the dispensing module can also be set up and designed to hold a waste roll.
- the dispensing module can be attached to a holding device of the RFID system, in particular suspended in the system, which allows lateral displacement transversely to the running direction and fine adjustment.
- the holding device can be designed in such a way that the dispensing module can also be rotated by, for example, 90° to the running direction. This means that inlays with a different orientation can also be donated to the carrier material.
- the dispensing module has at least one holder for an inlay roll and a dispensing tongue for dispensing individual inlays.
- the separation can take place with a cutting device of the dispensing module.
- the dispensing module can optionally have a further holder for holding a roll of cover sheet.
- a dispensing module could also have a further winder for receiving a waste web.
- at least one dispensing module preferably each dispensing module, can have a reading and/or detection device designed and set up for, in particular, contactless identification of defective inlays.
- an ejection device for ejecting defective inlays from the manufacturing process further in particular designed and set up as a suction device for sucking off defective inlays and transferring the defective inlays into at least one collection container, can be provided.
- dispensing modules By using several dispensing modules, it is possible to design the dispensing modules for a lower number of cycles or assembly performance, so that the process of applying and, if necessary, cutting and checking the inlays can be carried out much more robustly and precisely in relation to the individual dispensing module.
- a control of the inlay dispenser modules can preferably be provided in such a way that if an operating function of a first inlay peel-off module, this interrupted operating function is preferably automatically taken over and/or continued by at least one further inlay peel-off module, in particular a subsequent inlay peel-off module in the transport direction of a carrier material stream of the carrier material, in particular with the taking over and/or continuation of the operating function at the same transport speed and/or transport direction of the carrier material stream he follows.
- the operating function particularly preferably relates to equipping the carrier material with isolated inlays.
- the inlay dispenser modules can be controlled in this context such that the takeover and/or continuation of the operating function with the additional inlay dispenser module is automatically terminated as soon as the first inlay dispenser module resumes or continues the interrupted operating function.
- the dispensing modules of the RFID conversion system according to the invention can preferably be arranged one behind the other or following one another in the transport direction of a carrier material flow, in particular with at least two dispensing modules being arranged in one lane or one behind the other on a track or linearly in a row.
- the placement performance of a dispensing module in the placement operation can be in the range of less than 20,000 products per hour, in particular for example 15,000 products per hour or less.
- the cycle time per inlay in the individual dispensing module can in particular be more than 100 ms, preferably more than 200 ms, for example 240 ms.
- the higher cycle times per inlay in the individual dispensing module allow sufficient time for an extensive good check of the products even at full production output, which is a decisive advantage.
- the inlay dispensing modules can be controlled in such a way that if an operating function is interrupted by at least one preceding inlay dispensing module in the transport direction of the RFID products, the interrupted operating function is preferably automatically interrupted by at least one in the transport direction subsequent inlay dispenser module is taken over and/or continued.
- At least one first inlay dispenser module can be provided as an assembly module and at least one further inlay dispenser module can be provided as a buffer module, with the inlay dispenser modules being controlled in such a way that if the assembly with the first inlay dispenser module (assembly module) is interrupted, in particular during Exhaustion of an inlay supply, which can be indicated when a minimum diameter of an inlay roll is reached, the assembly is preferably continued automatically with the additional inlay dispenser module (buffer module).
- the second inlay dispenser module then fulfills a buffer function. Both modules can achieve the same maximum placement performance and be designed in the same way.
- the clock rate of the buffer module can correspond to the clock rate of the placement module.
- the inlay peel-off modules can be controlled in such a way that if the loading of at least one preceding inlay peel-off module (loading module) in the carrier material track is interrupted, the loading is preferably automatic with at least one further inlay dispensing module (buffer module) following in the carrier material track in the material transport direction.
- the subsequent module then works as a buffer module.
- the invention also allows for several buffer modules to be provided or for the buffer function to be fulfilled by several dispensing modules.
- inlay dispenser modules can be arranged one behind the other in a single lane, with the inlay dispenser modules being controlled in such a way that they are loaded simultaneously with several inlay dispenser modules at clock rates that are reduced compared to the equipment with just one inlay dispenser module Donation Modules.
- a controller can also be provided in such a way that an assembly always takes place with only one inlay dispensing module.
- At least one first inlay donation module can be provided as an assembly module and at least one further inlay donation module can be provided as a post-donation module, with at least one faulty inlay of the first inlay donation module being detected and ejected and wherein a control of the inlay dispenser modules is provided in such a way that a faulty one is ejected by ejection Inlay gaps in an inlay flow that have arisen are automatically closed by dispensing a fault-free inlay with the additional inlay dispensing module (post-dispensing module).
- the post-donation module stores only “good inlays” that have already been checked for freedom from defects.
- Detection and ejection can be carried out with the first inlay dispensing module, which has a corresponding detection device and ejection device for this purpose. Because the gap is closed by the refill module, it is not necessary to stop the system or carrier material transport, nor change the transport direction of the carrier material, and in particular no relative movement between the first inlay dispenser module and the carrier material stream.
- the detection and, preferably, the ejection take place in particular with the first dispensing module, while the further dispensing module works as a post-dispensing module and can be arranged downstream of the first dispensing module in the transport direction of the carrier material, in particular in the web transport direction of the carrier web.
- the subsequent donation module then closes a gap that has arisen in the inlay flow due to ejection.
- At least two dispensing modules are constructed in the same way and/or are to be operated as an assembly module, buffer module and/or post-dispensing module as required.
- the control device is designed to determine the current or instantaneous operating mode of at least one dispensing module as an assembly module, buffer module and/or post-dispensing module, in particular of all dispensing modules, during the production of the RFID products depending on the current or instantaneous operating mode of at least one additional dispensing module , in particular of all other donation modules.
- At least one dispenser module can be adjusted, in particular displaceable, to the side of the lane, ie transversely to the transport direction of a carrier material stream or product stream of the RFID products.
- the laterally displaceable dispensing module can then, for example, be operated as a buffer module and/or post-dispensing module as required.
- the positioning of the dispenser modules on a specific carrier material track ie the adjustment of the position of the dispenser modules transverse to the transport direction of the carrier material stream or product stream of the RFID products, is preferably done manually and is preferably not changed during the manufacturing process of the RFID products.
- the positioning of the dispenser modules on a specific carrier material track is then constant.
- At least one dispensing module can also be provided as a jumper module and can be adjusted to different carrier material tracks laterally to the carrier material track.
- the jumper module can be positioned on a carrier material track either manually or automatically.
- only one dispensing module is provided as a jumper module and is controlled accordingly.
- a continuous production of the RFID products is particularly preferably provided, in which a start and stop operation of the carrier material web or the means of transport does not take place.
- each carrier material track being provided with at least one inlay dispensing module as an assembly module and at least one additional inlay dispensing module that can be adjusted laterally to different carrier material tracks, in particular shifted, as a buffer module
- the inlay dispensing modules can be controlled in this way be that the supply of inlays of the assembly modules, in particular the roll end of an inlay roll of the respective assembly module, is consumed or reached with a time delay, in particular with the beginning of the assembly with assembly modules arranged on different carrier material tracks taking place with a time delay.
- a specific control algorithm can be used, for example, to ensure that inlay rolls reach the end of the roll at different times and have to be replaced.
- An automated change with the help of the buffer module, which is used as a jumper, is then possible.
- the assembly with a buffer module according to the invention can in particular only take place when a upstream in the transport direction of the carrier material stream first inlay dispenser module (assembly module) due to a exhausted supply of inlays, for example when the end of an inlay roll is reached, and/or in the event of an operational disruption that can no longer fulfill the loading function.
- the buffer module can preferably stand still and not be used for loading or for loading another upstream inlay dispensing module that is arranged on another carrier material track and whose loading function is currently interrupted.
- a refill module according to the invention is preferably fitted only to fill gaps which have arisen as a result of ejecting faulty inlays that have been dispensed with a first inlay dispensing module (assembly module) upstream in the transport direction of the carrier material flow.
- the control of the inlay dispensing modules can in particular provide that a subsequent dispensing module is not used purely as an assembly module. Accordingly, the clock rate of the post-supply module can be correspondingly lower than the clock rate of an assembly module.

- Dispenser modules as assembly modules linearly one behind the other for single-lane or single-lane production of RFID products and integrated good inspection of the inlays using radio and
- FIG. 10 shows a schematic representation of the arrangement of several inlay dispensing modules in an RFID conversion system according to the invention to increase the system availability.
- the system concept of an RFID conversion system for the single-track production of RFID products is shown schematically.
- the assembly, ie the dispensing, of inlays 1a onto a web or sheet-shaped carrier material 2 takes place only with a first inlay dispensing module 3, which works as an assembly module.
- another inlay dispenser module 3 is provided, which is on standby with the inlay roll inserted.
- the operating function of the dispenser module 3 or the loading with the dispenser module 3 is automatically ended.
- the further inlay dispensing module 3 then takes over the assembly work without any start, with inlays 1b being dispensed onto the carrier material 2 from the inlay roll of the further inlay dispensing module 3 (FIG. 1b).
- the process is reversed as soon as the inlay roll of the further inlay dispensing module 3 reaches the end.
- an assembly change back to the first inlay dispensing module 3 takes place automatically, which then takes over the assembly work of the further inlay dispensing module 3 without any start.
- two inlay dispensing modules 3 arranged one behind the other are already sufficient to enable uninterrupted operation of an RFID conversion system during a roll change.
- Figs. 2A and 2B more than one further inlay dispensing module 3 is provided as a buffer module, for example three buffer modules according to the embodiment shown. A longer, uninterrupted production phase is possible thanks to the large number of buffer modules. This function can be achieved if a total of more than two dispensing modules 3 are installed, which can assume an assembly function.
- the assembly is preferably always carried out with only one dispensing module 3.
- the three further inlay dispensing modules 3 are automatically subsequently controlled by the machine control at the end of the inlay roll of a preceding dispensing module 3 and used for assembly. In this way, a longer production phase without operator intervention is made possible during a roll change, starting with the first peel-off module 3 and then subsequently in the further peel-off modules 3 . This gives the machine operator a longer time window to complete other tasks.
- FIG. 2B shows, for example, that the loading function of the carrier material 2 is taken over by a further inlay peel-off module 3 with inlays 1d at the front in the transport direction 4 after the inlay rolls of all preceding peel-off modules 3 have reached the end of the respective roll.
- FIG. 3 schematically shows the use of a further inlay donation module 3 as a post-donation module.
- two dispensing modules 3 arranged one behind the other are already sufficient to enable the detection and ejection of faulty inlays and to close any gap that arises by dispensing a faultless inlay 1d from the inlay roll of the subsequent dispensing module. If, for example, a faulty inlay is detected in the first inlay dispensing module 3, this is ejected. The resulting gap is not closed by the dispensing module 3, since this is not possible at high production speeds. Instead, the post-supply module 3 is in a waiting position with an inlay 1d that has been checked to be free of defects. As soon as the resulting gap has reached the refill module 3, this places an inlay 1d in the gap and thus closes the gap.
- the inlay dispensing modules 3 described can be constructed in the same way and can be used in particular by appropriate control as an assembly module, buffer module and/or as a post-dispensing module.
- 4 shows an example of the installation of five dispensing modules 3 in order to enable different sequences or functional assignments of the dispensing modules 3 in the case of a single lane.
- the first two inlay dispensing modules 3 can be provided for assembly.
- the two further peel-off modules 3 following in the transport direction can be used as buffer modules and take on the assembly function when the inlay rolls of the preceding peel-off modules 3 have reached the end.
- the further inlay dispensing module 3 that is at the front in the transport direction can be used as a subsequent dispensing module in order to close gaps that have arisen as a result of faulty inlays being ejected.
- the first four inlay dispenser modules 3 can also be fitted, with the foremost additional inlay dispenser module 3 can be provided for changing roles or as a subsequent dispenser module.
- the RFID system can continue to be operated with the remaining dispensing modules 3 .
- the machine control is able to form 3 new sequences with the remaining ready-to-use dispenser modules.
- inlay dispenser modules 3 can also be shifted laterally, that is to say transversely to the direction of the lane, relative to one another.
- the total production capacity of the RFID system with several tracks or tracks then corresponds to the sum of the individual production capacities of the inlay dispensing modules 3. This is shown schematically in FIG.
- multi-lane operation is also possible in such a way that a further inlay dispensing module 3 is provided as a subsequent dispensing module for each lane or lane.
- Each track then has a first inlay dispensing module 3 as an assembly module and a further inlay dispensing module 3 downstream in the transport direction 4 of the carrier material as a post-dispensing module in order to close gaps that have arisen as a result of faulty inlays being ejected.
- the ejection can preferably take place with the assembly modules, which are set up and designed accordingly. This is shown schematically in FIG.
- FIG. 7 schematically shows, in an exemplary embodiment with five dispensing modules 3, the simultaneous assembly of, for example, four material webs or tracks of the RFID conversion system with four first inlay dispensing modules 3, which fulfill the assembly function.
- Another inlay donor module 3 is designed as a jumper module that is adjustable laterally on all tracks and can step in for the first inlay donor modules 3 when their inlay rolls have reached the end.
- a smart control algorithm can ensure that the inlay rolls of the first inlay dispenser modules 3 reach the end of the roll at different times. At the beginning of a new production, it can be provided, for example, that the four first inlay dispensing modules 3 observe pause times of different lengths.
- a first inlay dispenser module 3 During the time in which a first inlay dispenser module 3 is paused, its assembly work is taken over by the further inlay dispenser module 3 as a stand-in module.
- the jumper module can be automatically moved laterally to the respective track on a linear guide.
- the algorithm behind the pause sequence can follow from the Gaussian summation formula.
- the RFID system can be operated with reduced power. If the inlay rolls of all five dispensing modules 3 provided in the exemplary embodiment shown have been changed for the first time, an initial offset has formed and the production speed can be increased. No further interruptions to operations are then necessary, since in future all inlay rolls will reach the end of the roll at different times.
- the RFID system can run without further interruptions.
- a combination of buffer modules and refill modules is also easily possible.
- a total of nine dispensing modules 3 are provided.
- At least one first inlay dispensing module 3 as an assembly module and at least one downstream inlay dispensing module 3 as a subsequent dispensing module are provided on each track.
- the first four inlay dispenser modules 3 - for example, four tracks of the system - do the actual assembly.
- Four further inlay dispensing modules 3 are available to replace a missing inlay or an inlay gap that has arisen by ejecting a faulty inlay with a good inlay as subsequent dispensing modules on the respective track.
- At least one other inlay donor module 3, preferably just another inlay donor module 3, is the other donor modules 3 in the transport direction 4 in front of them or arranged at the end of the module chain in order to be used as a buffer or jumper module that can be adjusted laterally on all tracks to be able to provide automated roll changes.
- This further inlay dispensing module 3 is set up and designed in such a way that it can be offset or shifted onto the respective track.
- the test is carried out by means of electromagnetic transmission, in particular via a high-frequency (near) magnetic field, and examines the correct functions of the antenna and microchip.
- a time window of up to 100 ms per inlay is required. For example, if a machine produces at a production rate of 60,000 products per hour, a theoretical time of 60 ms remains for the test per individual product. A comprehensive test is therefore not possible. According to FIG. 9, this can be remedied by a linear arrangement of a plurality of inlay dispensing modules 3, which are operated at a lower clock rate.
- the RFID conversion system can produce 60,000 products per hour.
- the production rate per Dispenser module 3 only 15,000 products per hour.
- This increases the cycle time for each inlay 1a-1d in the respective dispensing module 3 from 60 to 240 ms. This allows the inspection of the inlays 1a-1d to be shifted to the respective dispensing module 3, with sufficient time remaining for an extensive inspection of the RFID products even when the RFID conversion system is running at full capacity. This is represented schematically by the radio symbol 5 in FIG.
- the machine control of an RFID conversion system can also allow individual inlay dispensing modules 3 to be deactivated.
- the first and third inlay dispensing modules 3 assigned to a material track are deactivated, for example.
- individual dispensing modules 3 can thus be removed from the production process.
- the RFID system or its control device recognizes a changed operating situation of individual dispensing modules 3, preferably automatically, which preferably leads to an automatic adjustment of the sequences, i.e. the operating mode or functional assignment of the ready-to-operate dispensing modules 3, with these depending on the sequence as an assembly module, buffer module or post-donation module can be used.
- the entire system remains operational and production can continue with reduced performance or a reduced range of functions.
- the number of dispensing modules 3 is selected as an example. All dispensing modules 3 are preferably constructed in the same way, in particular in the manner of label dispensers. Each dispensing module 3 can be operated with a machine control, preferably and as required, as an assembly module, buffer or jumper module or post-dispensing module in the mode of operation described in each case. Appropriate holding devices for holding the dispensing modules 3 as required are preferably provided in the plant periphery.
