Definitions

  • the invention relates to a device for producing a multi-layer hose from paper webs provided at equal intervals with transverse perforations, from which hose sections are torn for sack production, with at least one perforating knife mounted in the machine frame and fastened to a rotating shaft, which provides the paper webs with transverse perforations and whose radial distance from the shaft can be changed for setting the format, with cross-gluing cylinders mounted in the machine frame, provided with cross-gluing strips and interacting with glue application devices, and with one of the laterally offset edges of the paper webs brought together via guide rollers before they are folded into a tube with a longitudinal adhesive roller providing the longitudinal adhesive seam.
  • Paper bags for example for packaging cement or other powdery or granular materials with high strength, are made from multi-layered tube sections, the Individual layers are glued together at the edges during tube formation and at the ends of the individual layers with cut edges lying flush one above the other (smooth cut) or preferably only partially overlapping one another in a staggered formation, so that the individual layers are glued individually during the formation of the bottom.
  • Such non-uniform gears consist of crank-loop gears, which due to their non-uniformity are subject to large accelerations and decelerations in their rotation, so that due to the resulting inertial forces, the machine can only run at a lower power in order to keep the resulting inertial forces within permissible limits.
  • the setting of the formats of the known machine is limited by the fact that with a reduction in the spacing of the transverse perforations, the arms carrying the perforation knives can only be adjusted radially inwards to such an extent that their rear ends, which project beyond the shafts, do not abut the paper web and damage them.
  • the known tube machine therefore allows format variability only to an extent in which the largest section lengths are approximately twice as large as the smallest, because if the distances were further reduced, the ends of the arms not equipped with a perforating tool would get in the way of the continuous paper webs .
  • the well-known The hose machine therefore does not meet today's requirements for format variability, since it is required to produce hose sections whose smallest lengths correspond to approximately one sixth to one eighth of the largest lengths.
  • the object of the invention is therefore to provide a hose machine of the type specified at the beginning, on which hose sections can be produced with high output and simple retrofitting, the lengths of which can be varied within a wide range.
  • this object is achieved in a device of the generic type in that four supports are arranged on the shaft at equal angular intervals for perforating knives which can optionally be attached to them and which have devices for adjusting their radial distance from each shaft.
  • the greatest distance between the transverse perforations in the paper webs can be adjusted by extending the supports to their greatest radial distance from the shaft carrying them and by attaching a perforating knife to only one support. If the smallest possible distance of the transverse perforations is to be set, the four carriers are set inwards to their smallest radial distance from the shaft and all four carriers are set with perforating knives.
  • perforating knives can be attached to mutually opposite carriers. Between the smallest and the largest adjustable distance of the transverse perforations, all formats can be adjusted by appropriately extending and retracting the carriers and / or arranging one, two or four perforating knives on the carriers. Since nonuniformity drives have thus been dispensed with in the tube machine according to the invention and the running speed of the paper webs in each case depends on the peripheral speed the perforating knife can be adjusted, the device according to the invention can be operated with high performance with wide format variability.
  • the invention can be implemented with particular advantage in devices for the production of so-called relay bags, in which the individual layers of the multi-layer hose section are also only partially overlapping one another in the longitudinal direction.
  • at least one perforating knife attached to a rotating shaft is provided in the machine frame for each of the paper webs which run separately from guide rollers and which provides the paper webs with transverse perforations which are offset in the longitudinal direction, and that on the shafts 4 carriers are arranged at equal angular intervals for perforating knives which can be optionally attached to them and which have devices for adjusting their radial distance from each shaft.
  • the cross-gluing cylinders are provided at the same angular intervals with four receptacles for cross-gluing strips, which are attached in the same number as the perforating knives.
  • the diameter of the cross-gluing cylinder By a suitable choice of the diameter of the cross-gluing cylinder, it can be ensured that an equal number of cross-gluing strips is provided in accordance with the number of perforating knives used, so that spreading out the transverse adhesive strips is done only in a small and in without an expensive change in the diameter of the cross-gluing cylinder Purchase takes place to an increasing extent.
  • the cross-gluing cylinders When converting the tube machine to a different format, the cross-gluing cylinders only need to be provided with a number of cross-gluing strips corresponding to the number of perforating knives, which can be effected quickly and easily.
  • the spacing of opposing receptacles of the cross-gluing cylinder expediently corresponds to the average, adjustable spacing of opposing supports of the perforating knives.
  • the staggered layers at the ends of the hose sections must be free of adhesive applications.
  • the longitudinal adhesive roll of constant diameter is provided over its circumference with four optionally closable recesses which prevent adhesive application to the edge areas of the paper web provided with transverse perforations.
  • 1 consists of, for example, three unwinding frames, not shown, in which paper rolls 1, 2, 3 arranged one behind the other are held, from which flat paper webs 4, 5, 6 are drawn off via guide rollers and unwinding and / or pulling devices.
  • two cross-gluing cylinders 12, 13 are provided in the machine frame behind the cross-perforating cylinders 8 to 10, the cross-gluing strips of which provide the paper webs 5 and 6 with transversely extending adhesive applications.
  • the cross-gluing strips 14 of the cross-gluing cylinders 12, 13 receive their glue applications in the usual way from glue application rollers.
  • the paper webs 4, 5, 6 are brought together for their bonding to form a multi-layer web.
  • An edge region of the web, on which the individual webs are laterally offset from one another, is provided by a longitudinal adhesive roller 16 with an adhesive application which forms the later longitudinal seam, the adhesive roller 16 being provided with cutouts 17 which ensure that the edge regions of the multilayered edge perforations are provided Do not apply adhesive to paper web.
  • the longitudinal adhesive segments lying between the recesses 17 or the longitudinal adhesive segment of the longitudinal adhesive roller receive their adhesive applications in the usual way from an adhesive application roller.
  • the multilayer paper web prepared in the manner described is then folded into a tube in a tube forming station 18, the respective overlap-free edge regions of the individual layers sticking together.
  • the individual tube sections 20 are then torn off from the paper tube.
  • the tear-off station is provided with a conventional tear-off mechanism, which consists of two rollers driven at different peripheral speeds, the front of which forms a holding roller and the rear forms a tear-off roller, the individual portions 20 being torn off by a cam-provided roller 21 in one counter rollers mounted on the movable carrier are pressed onto the holding and tear-off rollers.
  • perforation cylinders are shown schematically in different drawing positions.
  • Each of the perforating cylinders 8 to 10 has a central shaft 24, on which four tool carriers 25 are held, which are provided with actuating devices which allow their radial extension and approach to the shaft 24.
  • the devices for the radial movement of the tool carrier 25 can, for example, consist of two links articulated on the tool carriers 25, the other ends of which are connected in an articulated manner to sliders, which are displaceably arranged in opposite directions by adjusting means in the axial direction on the shafts 24.
  • one to four perforating knives 11 can be fastened on the tool carriers 25.
  • the tool carriers are each extended to different extents in the radial direction.
  • the tool carriers are extended the most, only one tool carrier 25 being fitted with a perforating knife 11, so that the greatest spacings of the transverse perforations can be achieved in this position.
  • the tool carriers 25 are set to an average distance, two opposing tool carriers being occupied by perforating knives 11.
  • the uppermost representation of the left column shows the carriers 25 moved into their innermost position, all of which are covered with perforating knives 11, so that the smallest spacings of the transverse perforations can be achieved.
  • the cross-gluing cylinders 12, 13 are shown, the receptacles 30 of which are attached to them at an invariable distance.
  • the individual shots 30 are each provided with a number of cross-adhesive strips 14 corresponding to the perforating knives 11.
  • the longitudinal adhesive roller 16 is shown, which is provided with cutouts 17 in accordance with the respective number of perforating knives 11 and cross-adhesive strips 14, each of which bridges the transversely perforated areas when the longitudinal adhesive application is applied.
  • the cam roller 21 is provided in the manner shown with one to four cams 36 which press the movable rollers against the holding and tear-off rollers of the tear-off mechanism with a variable number of cycles.
  • FIG. 2 shows a variant of the tube machine according to FIG. 1, in which a flat perforating perforating cylinder 40 is arranged in front of the tear-off station 19, the perforating knife of which cooperate with a counter cylinder 41.
  • the perforating cylinder 40 has the same structure and the same configuration as the perforating cylinders 8, 9, 10, so that a new description is dispensed with.
  • the tube machine is only provided with the perforating cylinder 40.
  • the perforating cylinders 8, 9, 10 can therefore be omitted.
  • the hose machine is equipped with both the perforating cylinders 8, 9, 10 and the perforating cylinder 40, which are then optionally brought into their operating position become.
