Definitions
- the invention relates to a method for controlling the edges of a film strip, which is fed into a form hopper of a device for producing tubular bodies from the film strip with an overlap seam by means of a guide wedge and then welded.
- the film strip which is initially lying flat, is formed into an endless tube in the form funnel, the respective film edges being guided one above the other into the tubular position by a guide wedge to form an overlap seam.
- the overlapping side edges are welded to a solid tube by the action of heat and possibly also pressure, subsequently cut to length and fed to further processing.
- Laminates are used as film strips, which have a central diffusion-inhibiting barrier layer between two outer plastic layers, optionally also with further plastic layers lying in between and, if necessary, connected by means of adhesive layers.
- B. can be carried out in the form of an aluminum foil.
- Such aluminum foils have layer thicknesses of between 0.01 and 0.04 mm and possibly also above them.
- inductive heat is generated in the aluminum layer, e.g. by high frequency using an RF inductor.
- the usual overlap of the side edges of the laminate is approx. 2 to 4 mm, in exceptional cases also below or above.
- tubular shape can also take place by means of outer and optionally inner drive belts, it also being possible to use an induction coil.
- a ferrite core can also be provided in the coil former for concentrating the field lines, so that the induction heat can be spatially limited and intensively transmitted.
- the plastic layers surrounding them are heated above their melting point, connected to one another, possibly under pressure, possibly compressed into a seam and optionally also shaped, and then cooled, for example by external and optionally also internal cooling rollers, by means of which the pressing also results in a permanent and shaped Weld is possible.
- Laminate film tapes for example for the production of laminate tubes, are usually produced in a width of approximately 1.2 m on so-called laminators and then wound up into mother rolls by a winding machine.
- a plurality of individual rollers with a width corresponding to the desired diameter of the tubes are produced from these mother rolls by means of a strip cutting machine. This creates several parallel single rolls across the width of the parent roll, each with different properties.
- the stress distribution occur in each individual role - e.g. T. considerable - differences that lead to unstable conditions in the pipe formation and / or in the welding unit.
- the object of the invention is to provide a method for controlling the position of the edges of a film strip with the features of the preamble of claim 1, which allows automatic control by scanning the position of the overlap seam without scanning, so that personal monitoring and manual control to avoid rejects can be avoided.
- Embodiments are preferably to be found in the subclaims.
- Fig. 1 shows a device for producing tubular body sections from a
- FIG. 2 shows an enlarged section of the device with a film funnel, a welding device and a line sensor
- Figure 3 is the same as Figure 2 seen from above (i.e. rotated 90 ° with respect to Figure 2);
- FIG. 4 shows a plan view in the axial direction of the inlet of the form funnel with a partial section along line AA in FIG. 1;
- Fig. 5 shows a partial section through the welding device along the line
- FIG. 6 shows a circuit diagram of the linkage of an image of a specific overlap seam temperature scanned by the IR line sensor with an evaluation unit and a control unit for rotating the form funnel.
- the device shown in Fig. 1 for the production of tubular body sections 1 has a single roll (not shown) with a ribbon-shaped film, for. B. a laminate film 2, the at least one enclosed by two outer plastic layers barrier layer, for. B. contains aluminum.
- the flat supplied laminate film 2 is formed around a welding mandrel 3, which is still arranged in the area of the flat laminate film 2 and is fastened in a suspension 4, by means of a form funnel 5 to form an endless tube 6 with overlapping edges 7, 7 '.
- the form funnel 5 is rotatably arranged in a holder designed as a bushing 8.
- a motor 9 is connected via a worm gear 10 consisting of worm wheel 10 'and worm 10 "to the form funnel 5 for rotation about its central axis.
- a guide wedge 11 is fixedly arranged within the form funnel 5, through which the two edges 7, 7' of the fed laminate film 2 into an overlapping position, the overlap area of the edges 7, 7 'of the film strip 2 is approximately 2 to 5 mm. In individual cases the overlap can also be larger or smaller, but it must correspond to the desired diameter of the formed Endless tube 6 be large enough to be able to produce a sufficiently firm overlap seam 13 in the subsequent welding device 12.
- the welding device 12 shown schematically in FIG. 5 consists of a high-frequency (HF) welding device with a housing 14, in which a coil former 15, optionally with further coil turns 16, is arranged on the side of the welding mandrel 3.
- a ferrite core 17 is arranged in the coil former 15, possibly also within the further coil turns 16. 1, 2 and 5, electrical lines 18 are indicated, via which the operating current is supplied to the welding device 12.
- a further ferrite core 17 ′ is inserted in the welding mandrel 3 in the upper curve opposite the ferrite core 17 of the welding coil. Due to the opposing ferrite cores 17, 17 ', it is possible to melt only a narrowly limited area of the respective plastic layers of the laminate film 2, which essentially only covers the actual overlap seam 13, through the aluminum layers in the overlapping edges 7, 7'.
- an electrical infrared line sensor 19 which records an image of the temperature profile within the melted area of the overlap seam 13 transversely to the longitudinal extent of the endless tube 6.
- the IR line sensor 19 is followed by a roller 20, which can be assigned a counter roller 21 in the welding mandrel 3, which serve as cooling and / or pressing or shaping rollers. Additional rollers 20 and counter rollers 21 can also be provided, by means of which the overlap seam 13 can be shaped and, if appropriate, additional cooling can also take place at the same time.
- the number of rollers 20 and possibly also the counter rollers 21 can be varied as desired and adapted to the particular shaping and cooling conditions.
- the endless tube 6 which then runs from the welding mandrel 3 with a fixed overlap seam 13 is fed to a cutting device 22 or a cutting device.
- a known cross cutter is provided, by means of which the desired length of the tubular body sections 1 produced thereby is cut off, which can then be fed to a further processing unit (not shown) by means of a conveyor belt 23, e.g. B. for attaching a tube shoulder with cap.
- Bores 24 for supplying a coolant, for example water, can also be made in the welding mandrel 3.
- the temperature profile of the practically still melted overlap seam 13 determined by the infrared line sensor 19 is fed to an evaluation unit 25.
- a target temperature profile dependent on the desired product is entered by means of the target value input device 26.
- By means of an IR analyzer 27 is z at certain time intervals. B. of two seconds, the actual profile supplied by the IR line sensor 19 is compared with the predetermined target profile, and the respective deviations z. B. egg or e 2 found.
- a signal converter 28 converts the respective deviation value z. B. ei or e 2 corresponding signals in a suitable for the motor 9 signal, and an amplifier 29 can amplify the signal.
- the motor 9 rotates the form funnel 5 and thus also the guide wedge 11 connected therewith via the worm gear 10 in one direction until the deviation ei or e 2 is compensated or compensated and the target profile with that by the IR line sensor 19 measured actual profile is congruent.
