Definitions

  • the roll thus realized is composed of a continuous band formed by a succession of bags subdivided one from the other by a perforation line of a pre-determined pitch.
  • the continuous band is generally wound around the said cylindrical core, axially holed, in such a way that the roll can be subsequently arranged in a rotatable manner on the axis of a distributor. In such a way, the user can easily unroll a bag and detach it from the remaining roll by applying a traction that causes the tear along the perforation line.
  • Such types of bags are very common and frequently used in the food industry, for example in supermarkets in order to put fruit or other food products into a bag.
  • the production line of such rolls of bags includes an unwinding section by means of which a continuous plastic band is unrolled from a mother reel.
  • the mother reel can have a width variable on the basis of the number of rolls that want to be produced and generally superior to the meter so as to be able to obtain at the same time even four or more rolls.
  • a longitudinal cutting and welding section is arranged in succession to the unwinding section in such a way that the band unwound from the mother reel is subdivided into many tracks, welded laterally and bent centrally. In such a manner, starting from a single band of a pre-determined width, a plurality of continuous bands of inferior width is formed.
  • the perforation section is included, which creates the tear line between a bag and the subsequent one along the band formed.
  • such a section includes the intervention of an operator who arranges manually on a spindle a plurality of cores on which the bands will be re-wound.
  • the operator must subsequently arrange manually the spindle in the machine and remove it as soon as the winding has been completed. Then, the operator will have to remove manually the rolls produced and arrange a new spindle in such a way as to begin a new winding.
  • the winding section used for winding strings of medicine sachets.
  • the winding section has a rotatable carrier on which two rotatable spindles are mounted and on which the strings are wound. Once a first roll is completed around the first spindle, the carrier rotates such that a new roll can be initiated.
  • US3782650 which corresponds to the preamble of claim 1, it is disclosed a winding section for winding a continuous band of bags around a core.
  • the winding section is provided with a feed path of the band and a winding device in the form of spindles for winding the band around the core. Accordingly with US3782650 , it has been proposed a solution for having a precise cutting of the band when a core has been completed by using a signal obtained from the perforating and sealing machine preceding the winder and an appropriate counting device.
  • the winding section (1) comprises:
  • the winding device (10) includes a support (11) rotatable around a longitudinal axis (12) and provided with at least a first (16) and a second spindle (17) connected to the support (11) in a rotatable manner around their longitudinal axis, for realizing the winding of the roll in formation, and being further sliding axially between an extended position, wherein they result emerging from the support (11) in a substantially orthogonal manner to it to realize the winding, and a retracted position.
  • the winding section (1) further comprises:
  • the controlling movement system (50, 51, 55, 100) is synchronized in such a manner that when it conducts a spindle (16, 17) in rotation in extended position to complete a first winding of a roll in formation, it moves the second spindle back from the extended position to the retracted position.
  • the roll formed eventually present on such a spindle, automatically falls, while, at the same time, the spindle itself results already arranged to load new cores for a new winding.
  • the controlling movement system now controls the rotation of the loader (3) to bring it in axis with the said retracted second spindle.
  • the subsequent extraction of such a second spindle spears the cores arranged on the loader and arranges it for the new winding.
  • the controlling movement system controls the moving apart of the loader (3) in such a way that, in proximity of the completion of the first winding, it can activate the subsequent rotation of the whole support (11) around its axis (12) and that causes an inversion of position between the two spindles (16, 17).
  • the second spindle placed in rotation first or during such a rotation of inversion, now intercepts the feed path for the band (200) and, after the tear of the band with the said tear means, begins a new winding on the cores.
  • the controlling movement system now controls the retroaction of the first spindle conducted by the support in the loading and unloading position previously occupied by the other spindle, so as to cause the fall of the rolls formed.
  • figure 1 it is represented, in an axonometric view, a part of the winding section 1 for the formation of a continuous roll of bags in accordance with the invention.
  • the other part as better explained below, has been omitted here just for the sake of the purposes of descriptive clarity of the drawings, since it is substantially identical.
  • Figure 1 therefore represents a support frame 2 for the mechanical winding elements, that is a loader 3 and a winding device 10 best visible in figure 3 .
  • FIG 1 it is highlighted the loader 3 closed on one of its ends by means of a base 3' and into which the cores 4 are placed for the winding, which result arranged extended in a piled up manner one on top of the other.
  • the base 3' thus impedes the fall by gravity of the cores contained into it.
  • Figure 2 shows a frontal view relative to the axonometry of figure 1 in order to better highlight the core loader 3 with the closure 3'.
  • the loader as also highlighted in figure 1 , is mounted oscillating around a rotation axis 150 supported by the frame 2.
  • the oscillation is obtained by means of the extraction/retraction of an actuator 55 (see figure 2 or figure 8 and figure 9 ).
  • the loader 3 includes a sling 60 provided with the said rotation axis 150 and into which one or more binaries for piling up the cores 30 are fixed.
  • a sling 60 provided with the said rotation axis 150 and into which one or more binaries for piling up the cores 30 are fixed.
  • four binaries are included in such a way as to realize four winding tracks, as better clarified in the present description below.
  • Figure 1 and figure 2 further highlight a rotative device 10 (better highlighted in an axonometric view of figure 3 ) comprising two discs 11 connected in a rotatable manner by a shaft 12.
  • a disc 11 is arranged with respect to the frame 2 in a rotatable manner around the central rotation axis 12.
  • the central rotation axis as better shown in figure 3 , is a shaft 12 that is connected rigidly to a further opposed disc 11 and in turn supported by its own support frame 2. In such a manner, with a single motorization a disc 11 can be activated capable of dragging in rotation also the disc 11 opposed by means of the shaft 12.
  • Figure 4 better highlights an overall view with the said frames 2 to which the respective rotative devices 10 are connected.
  • the two discs 11 include each one of them a first winding element 13 and a second winding element 14 arranged in such a way as to result symmetrical according to a central symmetry with respect to the shaft 12 of rotation of the disc.
  • the winding element 13 and the winding element 14 comprise respectively a disc 13' and a disc 14' mounted fixed on the disc 11.
  • the disc 13' supports a spindle 16 on which cores 4 can be loaded, as the disc 14' mounts a spindle 17 on which cores 4 can be loaded for the winding, as will be better described in detail in the functioning below.
  • the spindles (16, 17) are mounted in both a rotatable manner and an axially sliding manner with respect to their support disc (13'; 14') in such a way that an appropriate actuation system (50, 51) can control their longitudinal extraction and retraction, while a motorization 100, better described in detail below, controls their rotation around their connection axis.
  • Figure 3 highlights well the spindle 17 belonging to the disc 14' completely retracted while, in contrast, the spindle 16 belonging to the disc 13' results extended.
  • Figure 1 the lateral view of figure 2 and the axonometric detail of figure 5 , therefore, depict a functioning condition wherein the loader is oscillated in a position wherein the cores are perfectly in axis with the spindle 17.
  • the cores extended in the loader are driven in the spindle itself like a ring to the finger.
  • the spindle is for that purpose of the expansion type so as to block on it the cores speared.
  • the axonometric view of figure 6 better highlights the subsequent phase wherein the spindle 17 has been extracted, consequently spearing the two cores 4 while, subsequently, the loader has been rotated in retracted position around the axis 150.
  • FIGS 5 and 6 show in detail just one spindle 17 exiting from just one disc 11, it is clear from figure 3 and from the present description that the preferred embodiment of the invention includes two discs 11, equal and opposed, and therefore two identical spindles (16, 17) per disc 11 that work in a perfectly symmetric manner.
  • figure 5 represents in fact just two tracks 30 speared from the spindle belonging to a disc 11, but it is to be intended that a disc 11 opposed is included and from which another 17 exits to spear the cores arranged in the other two tracks 30 omitted in such a figure.
  • figure 7 and figure 3 highlight the control system of the extraction and the retraction of the spindles (16, 17).
  • a sliding bar 50 is highlighted on which a sliding block 51 results mounted slidingly.
  • the sliding block includes a grasping system (for example plier-like) with which to grasp the corresponding spindle when, after the rotation of the disc 11, this is arranged in axis with it.
  • Figure 3 in fact shows the grasping phase of a spindle (in this case the spindle 17) which has been retracted with the backward motion of the sliding block 51.
  • the rotation of the two spindles 16 and 17, as also the rotation of the central shaft 12 and therefore of the two discs 11, is controlled by an appropriate motorization system 100 by which each element can rotate in an absolutely independent manner from the other.
  • Figure 3 in fact highlights two motors 110 per part (preferably of the "brushless” type) and just one ratiomotor 120 which, by means of transmission belts and pulleys, transmit the rotation to the said elements in an independent manner.
  • two belts 400 and 410 per part connect each one respectively the central axis 12 to a spindle (16, 17), thus controlling their rotation around their axis.
  • two pulleys are used that are mounted idle on the axis 12 and connected by means of the said belts each one to a pulley arranged on the disc 11 and integral to a spindle in such a way that a rotation can be transmitted from the motors to the spindles independently from the rotation of the shaft 12.
  • the fact that the said pulleys are mounted idle on the axis 12 implies that the rotation of the spindles continues undisturbed independently from the rotation itself of the shaft 12. In such a manner, their rotation continues undisturbed also during the rigid rotation phase of the disc 11 around its axis 12, allowing to continue the winding also during the exchange.
  • the ratiomotor 120 by means of the shaft 130 and the belts 420 and 430, allows to vary, according to the need, the speed of rotation of the spindles (16, 17), which are absolutely independent one from the other.
  • the first belt 440 controls the rotation of the shaft 12.
  • a part of the motorization is visible in the axonometric view of figure 4 and highlights the disc 1 which is rotatable with respect to the frame itself.
  • the rotation of the disc is therefore controlled by "steep" substantially of 180° in such a way as to be able to exchange any time the position of the spindles 16 and 17, taking them in the insertion position in correspondence of the sliding block.
  • the winding section 1 further comprises appropriate tear means (60, 60', 61, 61', 150) which, once a winding around one of the two spindles is finished, allow the tear of the band 200 and, at the same time, the beginning of a new winding around the second spindle arranged in stand-by position.
  • appropriate tear means 60, 60', 61, 61', 150
  • the said tear means therefore comprise a pressing element (60, 60') and a counter-pressing element (61, 61') constituted each of them by a roller (60; 61) mounted in a rotatable manner around an arm (60'; 61'). Both the arm 60' and the arm 61' are in turn hinged in such a way that pressing element and counter-pressing element result oscillating.
  • Figures 8 and 9 in fact show a succession wherein the pressing element (60, 60') is rotated clockwise to intercept the path of the band 200, while, at the same time, the counter-pressing element also rotates clockwise to increase the tension on the band.
  • the combined action of the pressing element and the counter-pressing element induce a tension on the band that causes the tear.
  • rollers of the pressing element and the counter-pressing element are assembled idle on respective arms with a certain degree of mechanical resistance to the rotation as to induce the said tension on the band 200.
  • An air blow 250 is arranged integral to the pressing element in such a way that when the tear took place the air maintains the band against the spindle to begin a new winding (see for example figure 12 ).
  • a flexible pipe connected to the pressing element can be used, provided with a nozzle on one side and connected to a compressed air source on the opposite side.
  • Figure 10 shows a normal winding phase of the band 200 by means of the rotation of the spindle 17 on which the cores 4 are arranged.
  • the spindle 16 is loaded with other cores 4 and remains in stand-by position so as not to interfere with the winding.
  • the loader 3 is rotated externally to the disc in a rest position, as well as the pressing element 60, in such a way as not to interfere with the winding.
  • Figure 10 also shows, for further descriptive clarity, a lateral view of the same disc 11.
  • a lateral view is however rotated of 90° anti-clockwise with respect to its frontal view in such a way as to highlight well the two spindles.
  • the spindle 16 is placed in rotation around its axis while, at the same time, the rotation of the disc 11 around its axis 12 is activated in such a way as to invert the position of the spindles.
  • Such an inversion phase is clearly schematized in subsequent figure 11 and highlights a rotation of 180° of the disc 11 around its rotation axis 12.
  • the two spindles exchange their position, allowing the beginning of the tear phase.
  • the two spindles rotate together at an appropriate speed.
  • the tear phase is realized with the pressing element and the counter-pressing element which are appropriately rotated in such a way that the pressing element gets in contact against the new spindle 16, while the counter-pressing element tensions further the band.
  • a clockwise rotation of the pressing element is included that brings it in contact against the new spindle 16 which rotates around its axis with a tangential speed that coincides with the advancing speed of the band.
  • the counter-pressing element rotates clockwise in such a way as to pull further the band 200.
  • the combination of the contact of the pressing element against the band that slips on the new spindle 16 and the displacement of the counter-pressing element generate the sufficient tension for the tear.
  • the pressing element continues to maintain the contact against the spindle 16 for the sufficient fraction of time so as to force the head 90 of the band to wind around the spindle 16 in rotation, in particular around the cores 4 fixed to the said spindle.
  • the air blow 250 arranged integral to the pressing element 60, facilitates the beginning of the new winding, forcing the head 90 of the band to remain in adherence against the spindle in rotation.
  • Subsequent figure 12 shows the roll formed provided with the tail 80 of the band broken and the head 90 of the band that begins to wind on the core 4, arranged in rotation on the spindle 16.
  • Figure 13 and figure 14 show the subsequent phases wherein the new winding has begun and at the same time the unloading of the rolls just formed takes place.
  • Such an unloading phase includes, thanks to the independent motors used, the stop of the rotation of the spindle 17 and the subsequent longitudinal retroaction of the spindle 17 by means of the sliding block 51, sliding on the guide 50 of figure 3 .
  • the retroaction of the spindle 17, as shown in figure 14 therefore causes the fall of the rolls formed which are, for example, collected by an appropriate mobile unloading platform 70.
  • figure 15 shows an anti-clockwise rotation of the loader 3 which brings the cores in axis with the spindle 17.
  • the axis 17 is made to slide longitudinally through the sliding block 51 along the guide 50 in such a way as to spear the cores arranged on the loader in axis.
  • the loader is at this point rotated in rest position, as shown in figure 19.
