Definitions
- the invention relates to a sorting process for winding remnants, the remnants of a web-shaped semifinished product on the one hand, and on the other hand of winding sleeves, which consist essentially of a plastic material and which have elongated cylindrical sleeve bodies on which the semifinished product was wound, whereby for processing the remnants of the web-shaped semifinished product the remainder of winding cores in the winding remnants are detected and sorted out.
- Web-shaped semifinished products with web widths of up to several meters are generally known in diverse forms in the context of industrial production processes and are preferably made available for processing in coils with diameters of up to several meters.
- Essentially flexible semi-finished products are wound on winding cores which, in particular, on the one hand at the beginning of the winding up and on the other hand at the end of the unwinding give the winding the stability required for the winding process.
- winding cores which, in particular, on the one hand at the beginning of the winding up and on the other hand at the end of the unwinding give the winding the stability required for the winding process.
- papers for industrial newspaper and letterpress printing, cellulose webs for the production of hygiene and cleaning wipes as well as the unmanageable variety of foils, textile fabrics and knitted fabrics are made available as sheet-like semi-finished products on such winding cores for further processing.
- the web-shaped semi-finished product is often unwound from the winding tube at speeds of up to several meters per second.
- this results in increasing rotational speeds of the winding with decreasing diameter, which - in particular in connection with the likewise decreasing bending stiffness of the winding - leads to warping of the winding along the winding axis, to vibrations and, as a result, to overstretching and tearing of the web-shaped semifinished product and to buckling or break the winding tube.
- the web-shaped semi-finished product in order to avoid dangers and to avoid reduced product quality, is generally not completely unwound from the winding tube as part of the industrial manufacturing process, but remains on the with a length of up to several hundred meters exchanged winding tube.
- the winding tube with the rest of the sheet-like semifinished product is returned to the manufacturing process of the semifinished product for recycling.
- a remainder of a PE film web on a winding tube is torn in several stages, shredded and ground, melted again in granulate form and drawn again as a film.
- the winding tube is usually removed as a reusable item before the web-shaped semi-finished product is reprocessed and used again for a new winding.
- It consists essentially or even entirely of plastic material, i.e. is not electrically conductive.
- “essentially made of plastic material” is to be understood to mean, in particular, those sleeves which, in addition to plastic, can also have very small proportions of cardboard and / or paper, but which in themselves have no appreciable metal proportions.
- the winding sleeve Due to the high load, especially during the tensioning process (i.e. before the actual winding process), the winding sleeve can be damaged, so that fragments of winding sleeves - or even entire winding sleeves due to carelessness - can be hidden between the remnants of the web-shaped semifinished product. If such remnants of winding cores are not detected in the remnants of the web-shaped semifinished product and are not sorted out before they are reprocessed, they can lead to serious damage to the machines used, or at least to quality losses in the recycling product.
- winding tubes Since the ends of the winding tubes are extremely stressed during the winding and unwinding of the web-shaped semifinished product, winding tubes have been constructed for decades from cylindrical elongated tube bodies and adapters attached to the ends, the tube bodies being made of cardboard, paper or an inexpensive plastic to reduce costs.
- the adapters on the other hand, are usually made from higher-quality, correspondingly more expensive plastics with better strength and wear properties.
- US Pat. No. 3,547,367 already suggests that it can be removed from the sleeve body in a non-destructive manner.
- the invention is based on the object of proposing a sorting method for winding residues which are potentially loaded in such a way that a sorting which also makes sense from an economic point of view permits.
- the object according to the invention is achieved in that the winding remnants pass through a detector in a continuous stream and the remainders of winding cores automatically pass through the detector as they pass through, due to their influence which deviates from the influence of the web-shaped semifinished product an electromagnetic alternating field can be detected, the influence being caused by an electrically conductive component added to the winding tube.
- the winding residues are preferably roughly comminuted before passing through the detector in order to achieve a continuous flow of the winding residues.
- the detection of the remnants of winding cores on the basis of an alternating electromagnetic field enables on the one hand automation of the sorting process with essentially generally known components, on the other hand also advantageously remnants of winding cores are detected which are not accessible to the visual inspection under or between the remnants of the web-shaped semifinished product.
- DE 3423 866 AI and DE 3841 678 AI devices for separating metal particles or non-magnetizable electrically conductive metal parts from a solid mixture are known, which can consist of powdery, granular or lumpy material. In both cases, the electrical conductivity of the parts to be detected and eliminated is used. While in the case of DE 3841 678 AI a slide valve in is dependent on signals from a metal detector so that when the metal detector detects a metal particle, the slide separates part of the conveyed material through a discharge opening, in the case of DE 3423 866 AI eddy currents are induced in the non-ferrous metal parts with the help of an alternating electromagnetic field, which in turn make it possible to separate the parts magnetized in this way from a flow with the aid of magnetic forces.
- winding cores which essentially consist of plastic material and therefore do not have electrically conductive components
- detection and separation methods cannot be carried out without additional measures.
- Methods based on the interaction of certain parts with an electromagnetic alternating field can only be used if, as proposed according to the invention, the winding cores are provided with a component which, based on their influence in an electromagnetic alternating field, of the web-shaped semifinished product and the other plastic material of the winding core is distinguishable.
- the stream of the winding residues is preferably divided into segments, the segment detected by the detector being marked when the residues of the winding cores are detected and automatically diverted into a waste stream branching off from the stream of the winding residues.
- the segmentation of the current of the winding remnants can take place both concretely by partition walls arranged transversely to the direction of the current on the conveying means, and also purely virtually by the representation of the current of the winding remnants in the control device.
- the segmentation of the current of the winding remnants advantageously simplifies its representation in a digital control device.
- the segment loaded with remnants of winding sleeves can be guided out of the stream of winding remnants independently of the detector at a later point in time.
- a marking can in turn take place concretely - for example in the form of a color marking range - or virtually in a data record assigned to the relevant segment in a control device.
- a segment loaded with remnants of winding cores can in turn be guided automatically or manually out of the stream of the winding remnants into a waste stream.
- This waste stream can now be, for example, an in-depth visual inspection or - after a more detailed segmentation - a detector again are fed. In this way, on the one hand the manual effort of the sorting method according to the invention is minimized, on the other hand its error rate is considerably reduced.
- a winding tube on which a web-shaped semi-finished product can be accommodated which essentially consists of a plastic material and which comprises a cylindrical elongated tube body, the winding tube having a metallic foil which extends in a circumferential direction of the tube body ,
- the proportion by weight of the metallic foil in the total weight of the winding tube is less than 5%, preferably less than 2%, and for long tubes even less than 1%.
- the aim of the deliberate addition of metal to the winding tube is to ensure the detectability, but otherwise to keep the metal content as low as possible.
- a metal foil - preferably copper or aluminum - does not affect the mechanical properties of a winding tube according to the invention, on the other hand even a small piece of a metal foil moving in an electromagnetic alternating field with a current of non-metallic winding residues generates a clearly detectable interference signal. In this way, even small fragments of the winding tube according to the invention can be detected.
- a winding tube on which a web-shaped semifinished product can be accommodated which essentially consists of a plastic material and which comprises a cylindrical elongated tube body, the winding tube being provided on one end face with axially screwed-in metal bodies which have no holding function ,
- Such a winding tube according to the invention hardly differs in terms of the interference signal from the winding tube with a metal foil described above. Compared to this, however, the detectability of fragments is severely restricted.
- This winding tube according to the invention is particularly suitable for recycling, since the screws can be removed from the winding tube without great effort if required.
- the screw heads also - if they are arranged protruding from the end face of the winding tube - protect this end face from mechanical stress.
- a winding tube on which a web-shaped semifinished product can be accommodated which essentially consists of a plastic material and which comprises a cylindrical elongated tube body, the plastic fabric has electrically conductive particles at least in partial areas of the winding tube.
- a winding tube according to the invention as in the embodiment with a metal foil, and even to an even greater extent, even the smallest fragments can be detected.
- this winding tube is well suited for recycling because it consists of a uniform material - provided the particles are evenly distributed in the affected areas.
- the plastic of such a winding tube according to the invention is particularly preferably mixed with soot.
- Soot particles are advantageously particularly inexpensive and can be distributed particularly easily in a plastic material through the mixing and extrusion process as part of an injection molding process.
- metal particles - for example copper or aluminum dust - can also be added to the plastic.
- a winding tube according to the invention can in particular also have at the end - at one end or at both ends - a cylindrical adapter which can be attached to the end of the tube body and can be removed from the tube body in a non-destructive manner.
- the metal foil, the screwed-in metal body or the electrically conductive particles can be attached to the sleeve body, to an adapter or to both.
- the film can be arranged in particular by gluing to a lateral surface of the adapter according to the invention, preferably to an inner lateral surface.
- the film is advantageously exposed to lower mechanical loads than the arrangement on an outer lateral surface, since the adapter is generally inserted into the end of the sleeve body and is in contact with the latter on its outer lateral surface.
- the film is particularly preferably arranged in at least one pocket that springs back radially relative to the inner lateral surface of the adapter. In this way, the mechanical load on the film can also be reduced in the event that a cam engaging on a winding device "slips" on the inner lateral surface.
- 3a shows a third adapter according to the invention in an end view
- 3b shows the third adapter in a longitudinal section.
- Figure la shows a first adapter 1 according to the invention, consisting of a thermoplastic plastic material, for a winding tube on which a web-shaped semifinished product can be accommodated, the winding tube comprising a cylindrical elongate tube body in which the adapter 1 can be attached at the end.
- the winding tube, the sheet-like semi-finished product and the tube body are not shown.
- FIG. 1b shows a section through the adapter 1 along the section line designated “A-A” in FIG.
- the adapter 1 is sleeve-shaped, the radius 2 of its cylindrical inner lateral surface 3 corresponds approximately to half its axial length 4.
- the adapter 1 also has a cylindrical outer lateral surface 5.
- the inner circumferential surface 3 of the adapter 1 has a constant profile in the axial direction 9 of the adapter 1: the adapter 1 is provided with three springs 11 projecting from its inner circumferential surface 3 to a smaller radius 10, which engage in corresponding grooves of a drive bolt, which is again not shown intervene and on the one hand enable exact positioning of the reel and on the other hand a slip-free drive.
- the adapter 1 has three pockets 13 which spring back into its inner lateral surface 3 to a larger radius 12 and are each arranged centrally between the springs 11.
- a section of a metallic foil 14 is glued into the pockets 13 in the inner lateral surface 3 of the adapter 1.
- FIG. 2a shows a second adapter 15 according to the invention, which corresponds in its basic structure to the adapter 1 shown in Figures la and lb.
- FIG. 2b again shows a section through the adapter 15 along the section line labeled “A-A” in FIG. 2a.
- the adapter 15 has four in its axial direction 17 in its front face 16 the collar 18 screwed on metal screws 19. These metal screws 19 have no holding function.
- FIG. 3a shows a third adapter 20 according to the invention, which in turn corresponds in its basic structure to the adapters 1 and 15 shown in FIGS. 1a, 1b, 2a and 2b.
- FIG. 3b also shows a section through the adapter 20 along the section line labeled "A - A" in FIG. 3a.
- This adapter 20 has a section of a metallic foil 21 which is arranged between its inner lateral surface 22 and its outer lateral surface 23 and is encapsulated with the plastic material of the adapter 20.
