Definitions
- the invention relates to a method for creating a piece of hose from a flat web of flexible material, in particular of paper coated with plastic, by means of grooves. Embossing, cutting and folding, in which the web is withdrawn from a storage roll and conveyed intermittently, after being folded over in the form of a tube, the longitudinal walls of the web are continuously connected to one another by gluing, welding or the like, and the web is severed.
- a tube or tube is formed from a flat sheet of paper coated on both sides with plastic, which is intermittently pulled off a storage roll, after introducing creasing and embossing lines, filled with the liquid to be packaged and shaped by welding devices in individual packs, after which the individual Pieces of tubing, which are then separated from one another by transverse sealing seams, are separated by cuts which run through these embossing lines.
- the object of the invention is now to provide a method for producing such a piece of hose from a flat web and an apparatus for carrying out such a method, as described in more detail at the beginning. to create with which or at high throughput the web of elastic, flexible material is formed and separated into a tube in the shortest distance, the dimension of the tube piece being very precise.
- this object is achieved according to the invention in that before the longitudinal edges of the web are connected, the latter is partially cut at least from one longitudinal side transversely to the conveying direction, the formation of the tube takes place only by folding in these side fields divided by the incisions and the uncut part the web is held substantially flat supported and after connecting the longitudinal edges of the web its flat part is cut into the line to the incisions.
- the particularly novel idea of the present invention is to leave the material web in a piece at least partially until the final average, before the final average, i. H. before separating the individual pieces of hose, but to connect the longitudinal edges of the web with each other, so that at least one partial hose is formed.
- This tube is already divided into pieces by the cuts mentioned transversely to the long side of the web, which later form the length of the tube piece produced.
- the shaping of a tube with the material web partially remaining in one piece is a hitherto unknown work process, which permits various processing operations which were previously not possible when a tube was formed.
- the new method according to the invention achieves the formation of a piece of hose over the shortest distance if one looks at the material web drawn off the roll.
- welding with the shortest welding times is easy when using the most welding method possible.
- this makes the production of the desired packaging significantly cheaper.
- a so-called searching knife it is expedient if the mentioned incisions and the incision from the outside of the longitudinal edges of the web transversely to the conveying direction of the The path towards the center is not made by a knife like a pair of scissors, so that the incision has practically no width of its own, but it is more favorable if these are generally created with lines cut by punching. This enables areas to be punched out.
- the shape of these surfaces is elongated, i.e. H.
- double-line incisions can also be provided by punching out a narrow band.
- the flat web receives incisions of approximately the same length from both longitudinal sides, the inner end of which extends up to crease lines introduced into the web, and if the sum of the areas of the side fields divided by the incisions is greater than that Area of the middle, flat part of the path between successive pairs of cuts.
- the creasing can be done at the paper manufacturer. However, it is also possible to introduce the creasing lines with the machine using the method according to the invention at the beginning of the working process described here. These creasing lines run along the web conveying direction. They are used to fold the side panels formed by the incisions onto the central, flat part of the web formed thereby.
- a tube cross section can be formed, one part of which is flat and the other part of which is curved.
- the curved part is the one with the larger surface, in the case of the present example with the folded-over side panels. But on this are the longitudinal edges of the web, which are to be welded together.
- the welding in this form is advantageously stress-free, and this is also the reason why the simplest welding method can be used with very short welding times and without cooling time, preferably the use of constant contact heat. After the welding process there are no forces or tensions in the paper web which would put a considerable strain on the fresh sealing seam.
- the invention is advantageously further equipped in that the side panels folded in along the crease lines and formed into a tube piece are pressed together at one end next to the incisions to form a cone.
- exact dimensions have to be observed simply because of the injection molds.
- the shape of the tube piece was frustoconical. To achieve the truncated cone shape, one end of the tube piece must be equipped with a smaller diameter than the opposite end.
- the creasing lines can be most easily introduced into the web when they run parallel to the web conveying direction, the measure mentioned above must be carried out in accordance with the invention, namely the side panels at the relevant end of the hose piece in the region of the creasing line. If this compression takes place immediately before or during the welding process, the sealing seam absorbs the reduction in the diameter which is achieved by the compression beyond the crease line and immediately fixes this reduction in diameter. But with that you have in a very simple way a weakly cone-shaped piece of tubing, which, moreover, is even partially isolated, d. H. Is part of a track.
- the tube piece, after cutting through the flat web part is occasionally pushed aside transversely to the conveying direction of the web and raised to a circular cross section.
- the piece of hose was provided with a previously non-circular cross-section by the just held middle part of the web, z. B. approximately with the cross section of a segment of a circle. Therefore, it is favorable if the cross-section of this tube piece after the separation, ie cutting through in the line of the incisions previously made, is at least approximately in the form of a cylinder jacket, with one end, as mentioned above, of a slightly larger diameter than has its other end. so that one could speak of a truncated cone in an exaggerated representation.
- the injection mold then has the shape of a beveled mandrel as a counter-shape, a very slightly frusto-conical tubular body can be easily pushed onto the mandrel by suitable ejection devices, so that towards the end of the pushing process the narrow side of the truncated cone on the front of the mandrel is quite tight. ie with the suitable dimensions, comes to rest. This last-described side of the mandrel is then part of the injection mold, so that the tool halves can lie very precisely around the end of the hose piece.
- the method is expediently further designed such that, according to the invention, the web is cut transversely to the conveying direction by punching in such a way that the incisions running inwards from the longitudinal edges of the web have a width of at least 1 mm. While an incision literally represents a cutting line that has no width itself, a line of a certain width can be obtained by punching out. In other words, by using a punch knife along the incision to the desired depth, a strip-shaped part of the web which has a width of 1 to 5 mm, preferably 2 to 3 mm, can be removed.
- the advantage of making a punched incision i. H.
- a punched-out area in which the incision would otherwise lie, consists in the fact that the width of the band or punching incision resulting in the conveying direction of the web specifies a tolerance or a tolerance field, so that when finally cutting through the middle field of the web, namely of the field between the transverse incisions, a fixed knife or a knife that cannot move in the conveying direction of the web can be used.
- the arrangement and use of such a knife may be less complex than if one uses a so-called “searching knife” that is movable in the longitudinal direction of the web.
- the device for carrying out the method has cutting, feeding and folding devices according to the invention and is characterized in that a flat support plate, extending from the folding station to the cutting station, is held stationary in the conveying direction of the web in such a way that it is at least partially removed from the web It is included that in the conveying direction between the welding station having at least one constant contact heat jaw and the cutting station having a movable knife, feed drive rollers are arranged above and below the web, and that a distribution station with a hose erecting device is arranged downstream. With these measures, it is possible to make the web of flexible, elastic material, for. B. to serve to explain the invention here, coated on both sides paper web by cutting and folding into the above-mentioned tube shape with the segment-shaped cross-section.
- the folding station has levers which can be rotated about an axis lying in the web conveying direction and transverse mandrels which are fastened to them and which lie parallel to the axis. After cutting transversely to the longitudinal direction of the web to form the side panels, the transverse mandrels are rotated and pivoted inward about the axis mentioned about the support plate via the rotatable levers, so that the support plate is now almost completely encompassed by the material web.
- the welding counter jaws are arranged over the support plate and the longitudinal edges of the web to be connected are pushed onto these jaws while the transverse mandrels are still in be held in the swiveled-in position or holding rails hold this tube layer of the paper web up.
- the longitudinal edges to be connected lie directly between the welding jaws in the desired manner so that the hose can be formed, although part of the hose remains part of the continuous web in the form of the middle flat region of the web.
- an adjustable sliding cutting device with a photocell controlling the drive rollers is arranged in front of the folding station. This allows the device to be adjusted to different lengths of hose.
- the distance of the connecting line between the two incisions on the one hand and the photocell on the other hand will remain the same in all embodiments, but the distance of this cutting device or the photocell from the knives of the cutting station can be changed in accordance with the necessary division or number of hose pieces located between them.
- the device can therefore be converted to different products with simple means.
- the welding station has pressure jaws movable to the side of it next to the edges of the support plate at a small angle of inclination.
- an exact inside dimension of the hose piece can be achieved without a calibration mandrel.
- conical hose sections can be produced because a truncated cone is easier to pull onto a mandrel than an exact cylindrical jacket-shaped hose, especially when one considers that the one hose end fits exactly on that Mold part forming end of the mandrel must be applied.
- the conical hose section can now be created with the movable pressure jaws mentioned.
- At least one feed drive roller has a central recess on the circumference. Seen in the direction of conveyance of the web, the feed drive rollers are arranged behind the welding station. This does not result in any disadvantages for the promotion of the railway; because the train continues to the storage roll.
- the advantage of this arrangement of the rollers behind the welding station is, however, that the drive rollers hold the piece of hose down, so that there is practically a flat tube in cross section, the feed drive roller advantageously running directly over the weld seam. So that this is not undesirably claimed, the mentioned central recess is provided. So that a load on the seam, for. B. also the occurrence of undesirable shifts, advantageously switched off.
- edge protection which is a thin film in the area of the longitudinal seal seam. protected by the central recess, because otherwise the line contact may cause excessive pressures to be transferred to the edge protection film.
- connecting rails which extend across the width of the support plate and are attached to the ends of these rails are attached to the ends of these rails, while a slide is movably guided between the connecting rails in the distribution station.
- the slider is cyclically moved to the right or left transversely to the web conveying direction, depending on the direction in which the piece of hose separated by the cutting station is pushed aside. This is because the throughput or machine performance of the device according to the invention can be increased considerably. if one divides the tube pieces created by the web into two processing paths, because then each processing path has more time for further processing, especially when a cover or base is molded onto a tube piece. Towards the end of its respective stroke, the slide is always outside the path and thus outside the width of the support plate, which, however, is not absolutely necessary behind the cutting station.
- the slide can push the tube aside without great expenditure on the device. He expediently pushes it into a hose fitting on the respective side with a circular cross-section in which the hose piece then straightens up to the desired shape.
- the slide can preferably support the erection process by pushing to the end position. Then the next piece of hose will be ready behind the cutting station, so that the slide can reverse its direction of movement transversely to the conveying direction and push the next hose section in the opposite direction into another hose fitting, in which the same erection process is carried out as just described.
- the tube section can be pushed out of the tube fitting in the direction of its longitudinal axis by ejectors onto the spray mandrel already mentioned, where further processing, first of all the injection of the cover, can then take place.
- a simpler cutting station can be set up because, like in the case of a pair of scissors, two blades can be moved perpendicularly to the conveying direction of the web and allow an incision, but it is not necessary to search for the two blades or to move them in the longitudinal direction or conveying direction of the web is.
- the incision in the side fields which was in each case transverse to the web conveying direction, was made by punching in such a way that the resulting punch incision itself had a width of 1 to 5 mm, preferably 2 to 3 mm, has. This results in a tolerance range into which the fixed knife falls even when cutting through the middle piece of sheet, if the sheet is 1 or 2 mm from the center of the punching incision forwards or backwards.
- the cutting device is a punching knife that cuts out a partial surface.
- the incisions or punching incisions or punching fields which run inwards transversely to the web conveying direction can go either from the outer longitudinal edges to the respective perforation line running in the web conveying direction or only from this perforation line to just before the outer edge, depending on the situation whether the web receives the incisions or punching strips beforehand and is then pulled onto a storage roll or only in the machine described here. If the incisions or punching strips are already made during the paper preparation, which must not then extend all the way to the outside, the cutting device can also provide the tolerance field required for the fixed cutting knife on the outer longitudinal edge if it is a punching knife that cuts out a partial area.
- the paper web 1 is moved forward intermittently in the direction of the arrow 2 and that the embossing field 3 has already been introduced into the paper manufacturing factory. It is also assumed that the crease line 4 is already provided in the paper web 1.
- the incisions 6 running transversely to the longitudinal edges 5 are made in the web 1 in the machine described here, specifically by the knife 7 shown in FIG.
- the web is then moved in the direction 2 from the first right position to the next following second position.
- This is where the preparation for folding in the side panels designated by 10 takes place, by means of which a flat central panel 11 of the web 1 is formed.
- the boundary of the middle field 11 is formed by the two line lines 4.
- the folded state is shown in the third position from the right in FIG. 1, in which the web 1 has become narrower by the two side panels 10.
- FIG. 1 the representation of the fold-in is shown in FIG. 1 in such a way that first the fold-in takes place from bottom to top and then the second fold-in takes place from top to bottom, so that the edge 5, which is initially on the top outside, can be seen in the middle as a solid line while the lower longitudinal edge 5 can only be seen in dashed lines.
- the web 1 then moves further from the third to the fourth position, which belongs to the welding station 12 and represents the preheating area 13.
- the heated welding jaw 14 running over the central longitudinal seam, which softens the plastic layers to be sealed together in the preheating section 13, so that these are then connected to one another in the actual welding station 12 in FIG. 1 to the left of the preheating station 13.
- the web 1 is compressed with the help of the pressure jaws 15 movable in the direction transverse to the web conveying direction 2 according to arrow 16.
- These pressure jaws form the cone shape or truncated cone shape of the one to be produced Hose piece in that they are arranged at a small angle a to the web conveying direction 2.
- the front end of the pressure jaws 15 seen in the transport direction 2 of the web 1 is narrower than the rear end.
- FIG. 2 This is a cross section through the fifth position just described in the welding station 12 along the line 11-11.
- Fig. 2 the cross section of the flat support plate 17 can be seen, the two Longitudinal edges 18 are chamfered in order to better adapt to the cross-sectional shape of the web 1 which has already been folded over in the form of a tube.
- the cold counter-jaw 19 is fastened with a step 20, in which the end edge of the lower side panel 10 which has been folded in first can be inserted, while the upper, subsequently folded in side wall panel 10 can be put over the then smoother surface.
- the flat web part 11 On the side opposite the cold counter jaw 19 and the support plate 17 from the side panels 10, the flat web part 11 is arranged. 2 shows the sector-shaped cross section of the tube, the longitudinal edges 21 and 22 of which lie under the heated sealing jaw 14. To better hold the side panels 10 in the hose shape shown in FIG. 2, guide rails 23 are preferably arranged.
- the flat subfield 11 of the web 1 is cut through at the point 27 exactly in the line of the incisions 6. This is shown in FIG 28 designated average runs across the total width X of the hose section and separates a hose section with the length Z from the other.
- a slide shown in Fig. 5 ensures the lateral discharge in the direction of arrow 30 or 31 into tube fittings 32, where the flat tube is erected in a circular shape.
- the web 1 is drawn in the conveying direction 2, pulled by creasing rollers 33 and the roller motor 34 with pressure roller 35.
- the creasing rollers 33 have the task of introducing the creasing lines denoted by 4 in FIG. 1, around which the foldings take place.
- the roller motor 34 pulls the paper web 1 from the creasing station 33 via a loop 36 to two further deflecting rollers 38 and 39. This transfer of the conveying force from the roller motor 34 takes place via the pressure roller 35.
- the roller motor 34 is controlled by the photocell 37.
- the loop 36 can assume different positions, e.g. B. also the position 36 'shown with broken lines above.
- the flat paper web 1 receives the conveying direction shown by the arrow 2. It travels through a photocell 40 which controls the feed drive rollers 24.
- the knives 7 make the transverse incisions 6 (or 9) transversely to the longitudinal edges 5 of the paper web 1.
- the distance d of the incisions 6 from the photocell 40 which should remain the same for all lengths of hose pieces, can be seen in FIG. 1 for converting the machine to different hose piece lengths, a calculated different distance from the knives 41 and 42 ( Upper knife and lower knife) of the cutting station 43 receives.
- the web 1 moves into the folding station, generally designated 44.
- levers 46 and 46 ′ respectively, rotatable about an axis 45 lying in the web conveying direction 2 for the opposite side and transverse mandrels 47 attached to it and lying parallel to the axis 45.
- this fold-in station 44 is also apparent from FIG. 4, in which a view is taken in the conveying direction 2.
- the transverse mandrel 47 or 47 ' is pivoted upward via the lever 46 or 46' along the arrow 48 or 48 ', so that the transverse mandrel 47 (as well as the one with the apostrophe provided transverse mandrel) is brought into position 47 ".
- the transverse mandrels remain in place, while the material web, ie the coated paper, comprises the support plate 17 in the manner of FIG. 2.
- the web section is completely welded in the welding station 12 by the two strips 21 and 22 shown in FIG. 2 being connected to one another by constant contact heat.
- a pneumatic cylinder 50 can be seen in the cutting station 43 at the top, the piston of which is connected at the turning point 51 to the short lever of the swivel arm 53 (up to the turning point 52).
- This "searching knife” is operated in such a way that, after an average has been achieved in position 27, the knives 41, 42 together with the swivel arm 53 pivot clockwise around the pivot 52, driven by the pneumatic cylinder 50. Then when the web to be cut, i.e. H.
- the partially cut hose moves into the position shown in FIG., the direction of rotation of the swivel arm 53 is reversed, so that after the incisions 6 of the web 1 have reached their end position at the point 27, when the photocell 40 stops the driving rollers 24 from commanding has given, the upper knife 41 moves up against the stop and can then perform the cutting process.
- the web runs into the forming station, generally designated 54. 6 and in the cross-sectional view in FIG. 5, which is taken along a section line V-V in FIGS. 3 and 6.
- this is also the distribution station 70, in which the individual piece of hose according to FIG. 1 is moved laterally out of the conveying direction 2 of the web 1 in the direction of the arrows 30 or 31. This movement out takes place by means of the slider 29, which is in its non-operational position outside the web width X, which can be found approximately in FIG. 1, although the hose section after leaving the support plate 17 has assumed a slightly different shape than shown in FIG. 2 .
- This hose section is now pushed to the right by slide 29, for example in the direction of arrow 71 in FIG.
- FIG. 6 shows the arrangement of ejectors 63, the front view of which can also be seen on the left-hand side of FIG. 5.
- the front sliding plate of the ejector 63 has projections 75, into which the piece of hose hooks up with certainty when it is ejected. In this way, the isolated piece of hose can be pushed out of the hose fittings 32 onto the mandrels 64.
- Fig. 1 the incision 6 is already shown as a double line, so that one can already see the punching incision 6 or the punching strip 6 here.
- this punched strip runs continuously from the outer longitudinal edge to the perforation line 4 running in the web conveying direction 2.
- this punch cut 6 does not extend all the way to the upper edge.
- the punch cut has already been made during the paper preparation, after which the web 1 is drawn onto a roll.
- the edge incision 9 are introduced, but this can also be made by a punch knife in such a way that the resulting incision itself has a width, ie is a punched strip.
- Both the incision or the punching strip 6 and the punching strip 9 that then results have a width of preferably 2 to 3 mm.
