Definitions

  • the invention relates to a device for producing and filling bags, starting from a tape wound on a spool.
  • bags made of flexible material are suitable for packaging granular or powdery substances, such as coffee or flour.
  • the known devices must be stopped for the operation of unthreading the bags from the winding mandrels and for transferring them to carrier boxes. These indispensable cyclical stays limit the productivity of the known devices, while also creating serious kinematic disadvantages.
  • the handling of the flexible and sensitive body of an empty bag, i.e. its alignment from horizontal to vertical and its transfer is therefore difficult.
  • the invention is therefore based on the object to provide a device for the complete packaging of bags starting from a tape wound on a spool, which on a vertical mandrel, the purpose is moderately equipped in its interior with a device for ejecting the bag during the movement of the winding mandrel, without the bag having to be rotated for filling.
  • the invention consists in the provision of a free end section of a band coming from a spool, already in a vertical arrangement and falling vertically downwards, which is leveled due to the gravity of the downward weight. Moreover, it is expediently arranged ickeldornen a plurality of vertical W cyclically down vertically sloping strip at the end of which are aligned with such a degree of parallelism and such proximity with respect to the vertical after falling below the edge of the light coming from the coil strip down that the flexible tape can be stably anchored or attached to the vertical mandrels without deviating from the correct flat arrangement.
  • a feature of a preferred embodiment of the machine according to the invention is that the band is cut from flexible material after its end is firmly anchored to the vertical winding mandrel.
  • a feature of a further preferred embodiment of the machine according to the invention consists in ejecting the bag from the winding mandrel by means of an ejection device which is inserted into the interior of the winding mandrels in such a way that it performs this operation with the greatest reliability even during the movement of the winding mandrels and without stopping them .
  • Another important special feature of this embodiment of the device according to the invention is the transfer of the empty bags into coaxial boxes underneath and synchronized in movement with the mandrels.
  • the invention relates to a device for the complete packaging of bags, starting from a band wound on a spool, which is characterized in that at the beginning of the operating cycle the band is directed vertically downwards and is arranged parallel to the flat wall of mandrels.
  • the free end portion of the flat band coming from the spool is already arranged vertically due to the longitudinal tension due to the gravity of the dead weight, which is naturally downward like a lead thread, and is in a stable arrangement with a for stable anchoring to the winding mandrel without deviation from the correct one suitable arrangement of flatness, parallelism and proximity to the flat wall of the mandrel.
  • the device according to the invention is set up in such a way that the cutting of the flat edge of the tape, which slopes vertically downwards, takes place only after the hanging end of the tape has been firmly anchored to the winding mandrel in such a way that that coming from the spool flexible tape cut off flat sheet or the tape section can be transferred to the final winding zones at any time without deviation from their vertical flat arrangement.
  • the winding mandrels are arranged vertically downward and describe a career in which they are at least in the zone of installation and removal with respect to the vertical plane in which the end section of the band is due to gravity , with a degree of closeness and parallelism, which allows the sheet to rest without deviating from the stable, vertical, flat, vertically sloping arrangement.
  • the bags already wrapped around the mandrels are arranged in a natural vertical arrangement with the filling opening facing upwards for the introduction of any substance to be packaged by gravity.
  • the mandrels be provided with an ejector having a movable bottom for ejecting from the inside with an axial action against the bottom of the bag for unthreading the winding mandrel in motion.
  • the device according to the invention is designed to eject the bags from the winding mandrels during their movement by means of a push rod which, in order to produce a coaxial passage of a pin acting on the inner movable bottom of each vertical winding mandrel, has a pin which acts with generally known kinematics.
  • the machine according to the invention for transferring the bags formed around the vertical winding mandrels is arranged by means of a push rod acting on the inner movable bottom of each winding mandrel in an associated plurality of boxes below, which are arranged coaxially at least in the zone of the transfer of the bags and are synchronized with the movement of the overlying winding mandrel, from which the bags are unthreaded during their movement, which in this zone is identical to that of the associated associated box.
  • the aisle of the plurality of vertical winding mandrels is designed as a circular or annular aisle in combination with analog circular or annular aisles of the underlying associated and co-synchronized plurality of boxes into which the bags are transferred in the synchronous transfer zone each assigned mandrel and box coaxially and synchronized with each other for the simultaneous transfer of the from the winding ejected and located in the box during the synchronous movement of both vertically entering bags.
  • the invention provides a significant increase in reliability and consequent greater operational productivity.
  • the packaging devices according to the invention are characterized by maximum safety and operational precision.
  • the machine according to the invention is used to form a band coming from a spool and to fill, weigh, condition and seal bags made of flexible material with a content of granular or powdery substances, such as flour, sugar or coffee, even under vacuum and also in continuous operation , as well as integrated upstream with an apparatus for the extrusion and joining of materials to flexible tapes supplemented with printed or incised decorations and provided with inner and outer heat-weldable layers.
  • granular or powdery substances such as flour, sugar or coffee
  • a tape 1 made of flexible material which comes from a spool or extrusion device, not shown, is shown schematically.
  • Pull rollers 2 feed the tape 1 and guide it downward, transporting it vertically in the direction of the arrow.
  • Fig. 2 it is shown that the free end portion 1 'of the tape 1 coming from the spool is already longitudinally stretched like a lead thread due to the gravity of its own weight and assumes a flat, vertical position parallel to a winding mandrel 3 and maintains it in a stable manner.
  • Fig. 3 shows that the vertically hanging end portion 1 'of the tape 1 during the movement to abut the winding mandrel 3, for example by means of a counter wall 4, does not change its parallelism with respect to the winding mandrel 3, since it already runs close parallel to this .
  • Fig. 4 shows that the tape section 5, with the help of known means, not shown, is cut from the tape 1 only when it is attached to the mandrel 3. From Fig. 4 it can be seen that the cut tape section 5 remains anchored vertically and stably on the winding mandrel 3 and always remains in this vertical engagement / anchoring arrangement in all subsequent phases of winding around the winding mandrel. It also results that the edge 6 of the section 5 is horizontal to form the horizontal edge of a vertical bag with an opening at the top.
  • FIG. 5 shows that the edge 6 of the band section 5 always runs horizontally during the subsequent operations of winding - the section 5 around the vertical mandrels 3.
  • FIG. 5 shows a circularly arranged plurality of vertical winding mandrels 3, which are arranged, for example, hanging downward along a circular raceway from a horizontal rotating ring.
  • F ig. 6 shows that an ejection device 7 for repelling the bag 5 already formed by winding around the respective winding mandrel 3 is arranged coaxially inside the winding mandrels 3.
  • This ejection process plays during movement in a cam track 11 arranged on a stationary drum 12 from which rollers 10 are guided, which are arranged at the end of a pin 9 for pushing the ejection device 7 against the inner bottom of the respective bag 5.
  • the headstock slewing ring is placed on a chain equipped with a large number of boxes 8; the boxes 8 are assigned to the winding mandrels 3 arranged above and synchronized with them in a zone for removing the bags 5 in order to accommodate the respective bags 5 to be ejected. It should be emphasized that the transfer of the bag 5 takes place by ejection from the inside during the synchronized movement and not when the machine is stopped.
  • Fig. 7 shows the arrangement of the headstock slewing ring for holding the winding mandrels 3 with a circular path over a synchronized and with the annular raceway of a plurality of boxes 8 to be assigned to match.
  • FIG. 8 shows another combination of a multiplicity of synchronized boxes 8 arranged on a circle, which are also associated with hanging mandrels 3 arranged above them, which pass through an identical annular track.
  • Fig. 9 shows an embodiment of associated synchronized circular raceways on which the boxes 8 and mandrels 3 are arranged.
  • the circular associated pair of mandrels 3 and boxes 8 "is flanked by an outer tangential circular carousel of boxes 8 ', into which the bags 5 are empty in a vertical arrangement with a top opening open for the transfer by known kinematic devices Filling and Ver sealed ready to be transferred.
  • an associated pair of synchronized mandrels 3 and boxes 8 are flanked tangentially by a filling carousel with an annular path, the boxes 8 'of which openly receive the vertical empty bags 5 with an opening above and pass them on for further packaging operations.
  • the invention includes all those packaging machines with vertical mandrels, which are provided with a device for ejecting the bag from the mandrel during movement, the ejector being inserted directly inside the mandrel to remove the bag from it by pressing on it Inside bottom of the bag formed by winding in a vertical arrangement are equipped.
  • the circular or ring-shaped rotating ring which carries the winding mandrels and which is assigned and synchronized above a plurality of boxes below, in order to transfer the empty bags into them during the synchronized movement, is a further feature of the invention.
  • the invention further includes all those machines which wind vertical sheets around a plurality of vertical winding mandrels in order to form already vertically arranged bags with the opening open upwards, which are transferred into a plurality of associated boxes lying thereunder during synchronized movements.
