Definitions

  • the invention relates to a method for creating a piece of tubing from a flat sheet of flexible material, in particular of paper coated with plastic, by means of creasing, embossing, cutting and folding, in which the sheet is pulled off a storage roll and conveyed intermittently, after after folding in Slender shape - 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 removed from a storage roll, after introducing creasing and embossing lines, filled with the liquid to be packaged and formed into individual packs by welding devices, 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 creating such a piece of hose from a flat web and to provide an apparatus for carrying out such a method, as described in more detail at the outset, with which the web is made of elastic at high throughput , flexible material in the shortest Route is formed into a tube and isolated, 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 one piece up to the final average, at least partially web-shaped, before the final average, 'i.e. 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 invention achieved by the new method, the formation of a piece of tubing on the shortest route, if the pulled from the roll M ateri- considered albahn.
  • welding with the shortest welding times is possible using the simplest welding method. However, 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 done 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 lines are generally created with "incision" by punching. This enables areas to be punched out.
  • the shape of these surfaces is elongated, i.e. Instead of the line-like incisions, 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 the 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 serve to fold in the side fields formed by the incisions on the middle, planar part of the web formed thereby.
  • the invention is advantageously further developed in that the side panels folded in along the creasing lines and formed into a tube piece are pressed together at one end next to the incisions to form a cone. It was explained at the beginning that when a cover is molded onto one end of a piece of hose, exact dimensions have to be observed simply because of the injection molds. It has also been shown that it is extremely difficult to form a tube or a piece of tubing with exact internal dimensions in such a way that these could be pulled onto a mandrel, for example. Such mounting would be feasible if, according to an inventive concept, 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 occurs immediately before or during the welding process, the seal takes off the reduction in the diameter, which is achieved by the compression beyond the crease line, sews on and fixes this reduction in diameter immediately. But with that you have in a very simple way a weakly cone-shaped piece of hose, which, moreover, is even partially isolated, ie part of a path.
  • the piece of hose is pushed aside occasionally 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, for example with the cross-section of a segment of a circle, through the middle part of the web that had just been held.
  • the cross section of this piece of hose 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 when exaggerated.
  • the shape has a tapered mandrel also a very weak frusto-conical tubular body can be seen easily by suitable ejectors onto the mandrel defer, so that the end of the pushing action, the narrow side of the Ke g elstumpfes on the front of the mandrel quite tight, ie with the appropriate 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 incision which runs inwards from the longitudinal edges of the web te 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-out incision is that the width of the strip or punching incision resulting in the conveying direction of the web specifies a tolerance or a tolerance field, so that the final one Cutting through the middle field of the web, namely the field between the transverse incisions, a fixed knife or 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 a so-called "searching" knife which is movable in the longitudinal direction of the web is used.
  • 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 bring the web of flexible, elastic material, for example the paper web here used to explain the invention, to both sides by cutting and folding it 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 above 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 formation can take place, although part of the web also in the form of the middle flat area of the web is still part of the continuous web remains.
  • an adjustable sliding cutting device with a photocell controlling the drive rollers is arranged in front of the folding station in the web conveying direction. 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 according to the necessary division or number of hose pieces in between can be changed.
  • the device can therefore be converted to different products with simple means.
  • the welding station has pressure jaws movable to the side next to the edges of the support plate at a small angle of inclination to the latter.
  • 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 aforementioned movable pressure jaws.
  • a 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. This means that the seam is stressed, e.g. also the occurrence of undesirable shifts, advantageously switched off.
  • edge protection which is a thin film in the area of the longitudinal seal seam, is also protected by the central recess, because otherwise the line protection 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.
  • the slide 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. It is more expedient if the tube or the tube piece in the conveying direction behind the cutting station is empty on the inside, so that the slide can push the tube aside without great expenditure on the device.
  • the slide can preferably support the erection process by pushing to the end position. Thereafter be completed after the D urchschneidestation the next length of tubing, so that the slider its direction of movement transversely to turn to the conveying direction and can push the next section of tubing in the opposite direction -in 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.
  • the cutting device is a punching knife that cuts out a partial surface.
  • the incisions or punching incisions or punching fields running from the outside transversely to the web conveying direction can go either from the outer longitudinal edges all the way to the respective perforation line running in the web conveying direction or only from this perforation line to just before the outer edge, depending after whether the web receives the cuts 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 then not extend up to the outer edge, 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 part 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. On the other hand, at a distance a from the embossing field 3, 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. 3.
