Definitions

• the invention relates to a method and a device for the continuous filling of a predetermined amount of a product, in particular a beverage or food, in packs produced from packaging material, preferably provided from a roll, in particular cardboard-plastic composite material.
• a wide variety of devices for filling liquid, granular, powdery and / or solid products into portion packs are known from practice.
• systems which initially produce the packs to be filled from a raw material or semi-finished product.
• Such composite packs usually consist of inside and outside with a PE-sealed cardboard carrier material and, if necessary, also have further layers as an oxygen barrier layer, light protection layer or the like.
• compound packaging for UHT milk contains an additional aluminum foil as a light protection layer.
• the individual layers are laminated from the raw materials to be used to form a composite material, which is then printed and separated. After appropriate pre-folding, creasing,
• the rolls are shaped, cut, filled and sealed in a bottling plant.
• the end product is a package filled with the corresponding product.
• packs with defective inner surfaces are brought onto the market, because after the pack has been closed, the defects caused by the mostly non-destructive quality checks cannot be recognized. It cannot be completely ruled out that packs with faulty outer surfaces or faulty pressure reach the end user, because these packs are usually palletized in sales trays immediately after leaving the filling machine.
• the invention is therefore based on the object of designing and developing the above-mentioned method and the corresponding device in such a way that defects in the composite material and / or defects in the filled packs are recognized and the corresponding rejects are disposed of from the production process.
• this object is achieved in that a central control system collects information data about the manufacturing process of the packaging material, the integrity of the packaging jacket and / or the open packaging and the filling process before, during and after the filling, and thus influences the production process that defective or damaged packs are not filled and that unfilled or filled, but leaky or damaged packs are removed from the ongoing production process.
• the device for carrying out the method has a central control, a plurality of detectors for collecting data for the central control and at least one discharge device for discharging non-filled or filled, but leaky or damaged packages.
• Individual solutions for quality control in connection with filling machines are already known:
• DE 43 32 645 C2 discloses a machine for filling beverages in bottles which have been checked for integrity, and which has a multiplicity of rotating filling elements, the liquid valves of which can be switched individually by a common control device.
• the machine is also equipped with an input device in which the bottles are individually separated and continuously transferred to the machine from a feeding transport device in synchronization with the machine circulation, and with an output device which is followed by a final inspection device directly or with the interposition of closing and / or labeling devices , Mistake.
• the final inspection device checks the bottles for underfilling and removes them from the bottle flow if necessary.
• this machine has an input control device which checks the bottles for errors in the area of the input device and, upon detection of an error, emits a signal to the control device for keeping closed the liquid valve which is assigned to the bottle identified as defective during the following circulation.
• the input control device consists of three video cameras which generate the switch-off signal via image recognition devices for error detection.
• the final inspection device which checks the bottles for whether they are underfilled, has a video camera and an ejection device in the exemplary embodiment shown. The bottles are thus checked before and after the filling process.
• EP 0 378 052 AI describes a packaging device which has a bag-forming machine and is used to produce bags to be filled with bulk goods from a wrapping material band which is fed to the bag-forming machine via an input device.
• the input device has a control device for detecting defects in the wrapping material and deflection means which, in the event of a wrapping material band defect, drop the beginning of an incoming band section into a separation container.
• WO 98/05558 describes a method and a device for detecting design errors in a packaging made from a two-dimensional blank. Sections of the packaging have areas with contrasting colors which are optically scanned. The scanning results are fed to an electronic control unit for comparison with stored parameters. If the scanning results do not match the saved parameters, the packaging in question is considered defective.
• the embodiment shown in the drawing relates to the control of a packaging for holding yoghurt cups.
• the solution according to the invention is therefore based on the finding that data information from a wide variety of surface controls and other control systems are recorded and processed uniformly by a central control. According to the invention it has been achieved that defective packs are sorted out and removed where it is in the In terms of the entire manufacturing and filling process, the cost is cheapest.
• the acquisition of data about errors in the central control system which occur during the production of packaging material can - spatially and temporally separated - information about the

• Another advantage of the invention is that the data recorded in the central controller can be evaluated for the production of an exact cost statement for the packaging material manufacturer by means of a process recording software.
• costs can be saved by the bottler, since the bottler only has to pay for the material for the perfect packs and charges the packaging material manufacturer for the rejects (and possibly the entire device according to the invention)
• Manufacturers of packaging materials due to the elimination of a quality control saving mean that the total costs of the production process due to the solution according to the invention are lower than in the case of conventional processes, for the detection of defects in the packaging material optical, electrical / electronic or mechanical detectors as well as weighing devices or the like can be used.
• the discharge device provided at the end of the production process can also be provided with means for sorted discharge, such as a double switch, in order to not only sort out reject goods in addition to the product line of flawless products, but also to separate inferior goods separately. In this way it is possible to sort out properly filled and impeccably tight packs, which, however, are subject to printing errors, for example, as inferior goods.

Specifically, these are an interface 9 for external packaging material production, an interface 10, 11 for the surface inspection system, an interface 12 for the filling system, an interface 13 for the weighing control, an interface 14 for the discharge device and an interface 15 for the production acquisition software.
• the surfaces of the packaging material can be coated, laminated, printed, punched, perforated, untreated or refined by another method.

• Information about detected surface defects or printing errors is detected.

• the central control 5 receives information from the manufacturing process of the packaging material roll production.

If the target value with the permitted deviations is not reached, the central control 5 again receives corresponding data information.

All data information is processed in the central control 5 and compared with predetermined target values and error classes. All data take into account the machine speed of the entire device.
