Definitions

  • the invention relates to a device for producing a plastic packaging with a plastic-coated paper tube, one end of which is at least partially closed by injection-molded plastic parts and the other end by folding and welding the tube material, with a cutting device, a folding device for the simultaneous formation of at least one Two tubes of cut-to-size sections cut from the web by the cutting device, with at least two mandrel wheels, which are arranged in a clockwise manner and rotate about a common axis lying transversely to the respective processing strand, with injection stations, one filling station and one corresponding to the number of processing strands Endless conveyor with a closing station and with a discharge conveyor.
  • the known device is based on a different principle, according to which the direction of travel of the paper web runs transversely to the direction of travel of the material or the pack in the processing strand before being separated.
  • the reason for this measure in the known device is that the paper fibers for stiffening the package should run transversely to the longitudinal axis of the tube.
  • the object of the invention is to improve the manufacturing device of the type described at the outset and to make it smaller so that the performance of the machine can be increased despite the reduced overall length and with the simplification of individual processing steps and units.
  • This object is achieved in that in a web distribution station some cuts cut from the web are distributed to form a plurality of processing ranks lying parallel to the running direction of the web in a corresponding number lying parallel next to one another transversely to the running direction of the web in such a way that one crosswise to the running direction the web extends a series of blanks, and that the endless conveyor in positions in a straight line continuation of the respective packing web has receivable receptacles for the packs, the packs also circulating on the lower strand.
  • the production principle was changed when using a plurality of mandrel wheels in that the paper web is laid in the direction of the general processing strands and the multiplication takes place by distributing cut blanks in the transverse direction of the processing strands.
  • This distribution can be carried out so quickly and quickly that the row of blanks extending transversely to the running direction of the paper web can be formed in a short time and then represents the initial step for the number of processing strands arranged in parallel next to one another.
  • the web distribution station according to the invention ensures that the individual processing strands are each supplied with a flat blank.
  • the tubes are in the area of the mandrel gears or sleeves in a manner known per se provided at an open end with plastic injection molded parts, so that the respective paper tube is closed at this end and with this closed end lying in the direction of travel then removed from the respective mandrel wheel and into the receiving position of the endless conveyor described further brought. It is also advantageous here that the respective receiving container on the endless conveyor can be brought into a receiving position arranged in such a way that the paper tube, which is injected on one side, can be brought in a straight line from the mandrel wheel directly onto the endless conveyor.
  • the paper tube can be aligned in a suitable position in the region of the endless conveyor, ie with the open bottom facing upwards; that the tube is filled in this position; and the package can then be completely sealed by cross sealing.
  • a conveyor then takes the finished and filled packages from the endless conveyor and leads them to further treatment stations, e.g. B. a station where several packages are bundled into a multiple container by shrinking or the like.
  • the measures according to the invention leave sufficient time (also cooling time) for each paper tube to partially close its one side with injection molded parts. Nevertheless, the performance of the machine is increased not insignificantly, and yet, due to the clever design and arrangement of the individual processing units, the space required is the total machine reduced.
  • the blanks and the tubes formed from them are guided in a straight line up to the entry into the endless conveyor, where processing takes place on two levels and at the same time the packs are turned into the ultimately desired position. If the running direction of the discharge conveyor runs in the direction of the axes of the mandrel wheels or the axes of the deflection wheels of the endless conveyor, the length of the machine can be considerably reduced.
  • the design and surprisingly expedient assignment of the individual structural units to one another advantageously allows the packaging to be produced quickly and optimally, especially since no unnecessary embossing lines have to be provided in the paper tube.
  • the pack is removed from the roll and then from the flat blank, processed and manufactured, and the final shape of the paper tube is immediately produced during the first folding, namely in the folding device mentioned above, so that unnecessary intermediate steps which would only be due to the production, are omitted according to the invention.
  • the web of the respective paper tube lies in a horizontal straight line during the transfer from one station of the device to the next from the folding device to the receiving position of the endless conveyor.
  • there is a straight plane which extends from the web distribution station to the receiving position of the endless conveyor. Even in the area of the endless conveyor, this processing path does not actually change, because it is only in an upper run and dividing a lower strand so that processing can take place in both strands, although the two strands are parallel to the horizontal, straight plane mentioned; the upper run offset by the radius of the deflection wheel and the lower run down.
  • the longitudinal direction of the receptacle which is horizontal in the receiving position, is vertical in the dispensing position.
  • the paper tube is guided in a straight line in the aforementioned horizontal plane up to the receiving position of the endless conveyor in a direction which is parallel to the longitudinal direction of the receiving container in the receiving position.
  • the filling and closing station are arranged in the area of the endless conveyor, next to and in a functional connection to the latter.
  • the production machine can be considerably shortened, in particular if the finishing of the cross-sealed base of the pack is carried out in the region of the curved transition from the upper run to the lower run and in some cases still in the area of the lower run.
  • a further shortening of the machine is obtained if, according to the invention, the discharge direction of the discharge conveyor is parallel to the common axis of the mandrel wheels, at least in the area of the endless conveyor. Then the finished, closed package can be removed from the vertical delivery position described above by the endless conveyor and guided to other processing units.
  • the folding device described which immediately produces the finished sleeve or the paper tube from the flat blank, has, in an advantageous further embodiment of the invention, rollers supported on movably driven arms, a support mandrel and a movable welding jaw, all of which are arranged next to one another and can be brought into engagement with one another are. If one passes through the longitudinal center line of these three parts, i. H. of the bearing of the arms, the rollers, the support mandrel and the movable welding jaw a connecting line, then this is expediently perpendicular to the straight plane, which is preferably horizontal, so that the connecting line is preferably vertical.
  • the support mandrel is expediently at such a height that the supplied, flat cut comes to lie on the upper surface of the support mandrel, namely below the arms and the rollers. If the arms are then controlled in a corresponding sequence, as will be described below, the blank can be rolled around the support mandrel and brought to longitudinal sealing on that side of the support mandrel which is opposite the arms. This is the side where the welding jaw is movably arranged. This expediently moves towards the underside of the support mandrel to produce the longitudinal sealing seam, seals the edges of the previously flat and now tubular blank and then moves back to the starting position at a distance from the support mandrel.
  • At least one row of at least one recess for a package-containing receptacle in the form of an endless chain all around and touching each other in a straight strand is drivably supported and drive and / or deflection wheels are arranged one behind the other in a straight line continuation of the packing track.
  • at least two or more receptacles are located one behind the other or one receptacle is equipped with a plurality of recesses arranged one behind the other.
  • In the running direction of the endless conveyor there is one receptacle next to the other, so that they form a row and circulate in the form of an endless chain.
  • the receptacles touch each other in such a way that they slide against one another without obstructing one another. It would therefore be sufficient if the respective receptacle in the area of the drive and / or deflection wheel is engaged and driven by the endless conveying element, while in the area of the straight run the drive takes place due to the thrust effect of the receptacle located immediately behind. This ensures exact positioning and precise speed.
  • each drive and deflection wheel has radial arms with grooves on the outer ends for releasable engagement with pins of the receptacles.
  • the respective receptacle can actually be guided, moved and driven in the curved areas of the endless conveyor by the drive and deflection wheels, and in the other areas the receptacle disengages from such drive elements which are connected to the endless conveyor element, such as e.g. B. the radial arms on the wheels, or a chain that connects the two wheels in addition to the receptacles.
  • the grooves, into which the pins can run in and out, enable the engagement and the disengagement to come out evenly and precisely.
  • an adjustable depth bracket is further attached to each recess of the receptacle, e.g. B. in the form of an L-shaped rod or the like, which is slidably mounted in the longitudinal direction of the paper sleeve to be accommodated, paper tubes of different lengths can introduced and kept at the exact height along the path of the endless conveyor.
  • a receptacle can, for example, have an elongated plate that extends from one end over the entire width of the endless conveyor to the other end and has recesses perpendicular to its expansion surface for inserting the paper tubes. From this plate in the area of the straight run of the endless conveyor, guide rods can extend over the length of the paper tube to be held at the edge of the recesses. The tube is inserted into the recess and guided by the rods so that it is held in the desired position with a slight clamping effect.
  • the pack can preferably be filled in the area of the upper run and provided with a transverse seal.
  • triangular, double-layered material lobes then stand out from the cross-sealed base (in the direction of the cross-seal seam), which must be folded over.
  • tube corner folding and attaching devices are preferably located in the area of the deflection wheel and thus in the area of the curved part of the endless conveyor.
  • the corners of the respective tube are folded in these areas, pressed in the next area and through at another location Warmers pinned. The finished tube is then forwarded to the conveyor.
  • the paper tube inserted into the receiving container in the receiving position is moved upward through 90 ° in the vertical direction in such a way that the open bottom end of the paper tube is arranged at the top, generally away from the endless conveyor.
  • the tube is raised in a further station of the intermittently advancing endless conveyor in order to fill the tube with filling material.
  • the paper tube is lowered again, and after the filling process has been completed, the endless conveyor switches to the next position.
  • the transverse sealing of the base is preferably only carried out in the position after the next. To the then not quite finished folding floor so the corners described above protrude outwards.
  • the protruding corners are raised by 90 °, while the longitudinal axis of the paper tube swiveled by 180 ° when the deflection wheel was converted. Then the cross seal seam of the bottom folding fastener has cooled sufficiently and is hardened so that it can be mechanically loaded. The filling material is then above the cross seal seam.
  • the contents fall onto the folding floor, in which the triangular flaps resulting from the folding are now pressed against the floor and sealed by heat in the next station.
  • This heat of sealing and also the heat from cross sealing in the sealing station can be taken up by the packaged goods with particular advantage, because this no longer at a distance from the folding floor (as in the area of the upper run) but by turning the pack around (in the area of the lower run) is in direct contact with the folding floor.
  • cooling times can advantageously be reduced further.
  • the filling material itself can therefore be used partially as a cooling medium.
  • a cooling device is provided on the conveying path of the lid molded onto the paper tube between the spraying station and the endless conveyor.
  • the cooling device preferably has nozzles for expelled cooling air. These nozzles are preferably evenly distributed over the entire quarter-circle path from the injection station to the pick-up position on the mandrel wheel and irradiate the freshly sprayed lid or the molded parts molded on in the lid area, so that they are sufficiently cooled and hardened when the paper tube, which is closed on one side, is pushed down from the mandrel wheel and into the receptacle brought.
  • the pack-making machine can now also be constructed in such a way that all drive units are arranged on the machine side which is at the rear of the machine. These drives located on the back of the machine favor the operation and maintenance for the personnel because the motors do not interfere.
  • the package manufacturing device can best be explained with reference to FIGS. 1 and 2, reference being first made primarily to FIG. 1 and the formation of the paper tube and then the finished package being described first without machine elements.
  • Some parts of the web, the flat blank and some stations of the paper tube or the pack are already provided with the same reference numbers in FIG. 2, as explained below with reference to FIG. 1 for a general understanding of the invention. It should be noted here that the distribution from one web to three webs applies to the preferred embodiment described here and, if desired, several processing webs can also be provided.
  • a paper web 2 coated with plastic on both surfaces is drawn off from a supply roll 1 and conveyed via a first upper deflection roller 3 to a downwardly sagging buffer loop 4, the outlet end of which is delimited by a second upper deflection roller 4a, by means of which the paper web 2 is laid over and is guided vertically downwards to a lower deflection roller 4b, from where the paper web 2 reaches an imaginary general processing plane which is straight and lies horizontally.

  • Edge protection is also ensured by pulling off a plastic strip 24 from a feed roller 23 and sealing it in the region 21 to the edge of the moving paper web 2.
  • the buffer loop 4 of the paper web 2 serves to continuously rotate the supply roll 1 if, for example, the first deflecting roller 3 ensures a continuous removal of the web 2 from the roll 1, while in the area 5 the paper web is conveyed intermittently.
