Definitions

  • the present invention relates to an improved machine, which, with a continuous operating cycle, makes it possible to pachage a plurality of rolls of various strap-shaped materials obtained by means of a plurality of longitudinal cuts of a wide strip of material fed by a roller.
  • Machines according to the preamble of claim 1 are known from WO-A-8 706 919 which discloses a machine with continuous operating cycle for the packaging in rolls of various strap-shaped materials starting from longitudinal cutting of said strao-shaped material of considerable length.
  • FR-A-2 303747 describes a station to discharge the finished rolls from a spindle provided that a series of supports suitable to receive, between each of them, a terminated roll.
  • a first problem of the conventional machines derives from the fact that they must be stopped each time the rolls of material reach the required diameter, for discharge.
  • the machine must also be stopped to change the cutting means or blades which make the longitudinal cut of the material, which reaches the machine in the form of a wide strip.
  • Another advantage of the improved machine according to the invention is that the movement of the supporting means of the terminated rolls, subsequently simply called “spindle” is reduced to a simply rotation, thus eliminating the complex movement of the spindles of traditional machines.
  • a further new characteristic of the improved machine according to the invention is that discharge of the rolls and loading of the cores take place with the spindle at a standstill.
  • Another particularly advantageous aspect of the improved machine according to the invention is the elimination of dead times to change the blades, as this machine is provided with at least two pluralities of cutting blades, the first of which is made immediately operative for a time corresponding to an efficient cut by the blades, while the second plurality, inoperative for the abovementioned time, is automatically carried to working condition without stopping the machine, while the first plurality of blades is simultaneously moved away from the work zone.
  • a further innovation of the improved machine according to the invention is that, to supply the cores, a single loader is provided, in which the cores are fed vertically, making this machine further simplified compared to the traditional type.
  • the improved machine according to the invention comprises, as a whole, a feed station 10 in which a roller of notable width is prepared, indicated with 12, from which, through the perfected machine according to the invention, a plurality of rolls as specified below will be obtained, starting from a series of longitudinal cuts on the strip of material fed by the abovementioned roller 12.
  • the machine Downstream from the feed station 10, the machine comprises a station 14, provided with a plurality of shafts or spindles on which the rolls of material will be formed.
  • a further station 16 is provided, in which the cores are loaded, then carried, as described below, to the station 14.
  • the improved machine comprises a further station 18 in which the terminated rolls are discharged to be sent, for example, to a stocking station not shown.
  • This station comprises supporting means 20, subsequently called “spindle”, which initially support the cores on which the strips of material obtained with a series of longitudinal cuts on the material coming from the roller 12 will gradually be wound.
  • the revolvers 24 can be revolved round their longitudinal axis so that the spindle 20 is carried, through rotation, donwards in the direction of the arrow F opposite a discharge unit indicated in the complex with 28.
  • the discharge unit 28 permits removal of the terminated rolls of material 22 from the spindle 20 and their temporary prearrangement on a supporting shaft 30 provided in the discharge station of the terminated rolls 18.
  • the discharge unit 28 a lateral view of which is shown in fig. 5, comprises a supporting bracket 31, above which are provided two uprights 32, which support a series of U-shaped sections 34, inserted in special seats of the uprights 32.
  • Said sections 34 form, as can be seen in detail in fig. 2, a substantially comb-shaped structure designed to receive the terminated rolls 22, each of which are positioned between two adjacent sections 34.
  • a hollow shaft 36 is longitudinally operated, in which the cores 44 of the core loading unit are positioned; this unit, through traverse in direction of the discharge unit 28 carries out removal of the rolls 22 from the spindle 20 and their temporary support on the shaft 30.
  • the shaft 36 is controlled by a motor 38, which, by means, for example, of a worm screw 40 controls its advances in the direction of arrow G of fig. 2.
  • the shaft 36 thus causes a transversal transverse of the bracket 31 on its means of support 42 and therefore the transversal transverse of the uprights 32 and terminated rolls 22.
  • the terminated rolls 22 are therefore positioned on the supporting shaft 30, freeing the spindle 20 on which a new set of cores 44 is positioned, again to drive the shaft 36.
  • the spindle 20 is now returned to its starting position by rotation of the revolver 24 in opposite direction to the previous one.
  • Discharge of the terminated rolls 22, with particular reference to figs. 3 and 4 takes place in the following way.
  • the supporting shaft 30 is connected to a control motor 46, which, by means of a mechanism of worm screw type or similar, can cause it to move back by a pre-established length (fig. 4) so that the terminated rolls 22 fall one at a time into a collection station, not shown, in the direction of arrow H of fig. 4.
  • the terminated rolls 22 are made fall at a time by returning to the initial position the comb-shaped structure provided with sections 34, which is connected to the shaft 36 by a mechanism described below with reference to fig. 4A.
  • connection between the shaft 36 and the upright 32 is obtained by means of a pair of small rods 33, which present, longitudinally, a slit 35 which extends for almost their entire length.
  • the small rods 33 are engaged at their ends with stop elements 39, respectively integral to the upright 32 and shaft 36.
  • the stop elements therefore slide into the slits 35 and therefore, when the shaft 36 moves in the direction of arrow G of fig. 2, the opposite ends of the upright 32 and shaft 36 can approach each other, coming into contact.
  • a turret 50 carried by the casing of the machine revolvingly by a revolving shaft 52, suitably shaped on one face to receive and discharge the spindles 20.
  • one end side of the turret 50 is illustrated, as, on the opposite end of the shaft 52, a corresponding, identical side will be provided.
  • the turret 50 is provided, on one side, with two shaped essentially semicircular hollows 54, each of them suitable to receive and support one of the ends of a spindle 20.
  • the distance between the hollows 54 will be such that the turret 50 can simultaneously support a spindle 20 supporting the cores 44, together with a spindle 20 supporting a plurality of terminated rolls 22, as results, in particular, from an examination of figs. 5D and 5E.
  • the turret 50 is represented with continuous line in the position in which it is about to receive a spindle 20 loaded with cores 44 thanks to the movement of an operative arm 56 of which more will be said later.
  • the adjacent hollows 54 are empty for the moment, as they do not support any spindle.
  • the revolver 24 is provided with suitable means of support, essentially positioned 180° from each other, provided to support a pair of spindles 20.
  • the revolver 24 is carried revolvingly by a shaft 55.
  • the spindle located on the left of the revolver 24 in fig. 5A is loaded with cores 44, while the spindle 20 on the right of the same figure is also loaded with cores 44, but on them are forming the rolls 22, as it is seen that they are being reached by the strips of material 72.
  • the revolver 24 is now given, in any known way, an anticlockwise rotation in the direction of arrow P of fig. 5A with such a speed, referring also to figs. 5B and 5C, so that the two spindles 20 gradually occupy the position previously occupied by the other.
  • the rotation of the revolver 24 is momentarily stopped (fig. 5C) and on the spindle 20, which is now located on the left, will be placed a plurality of terminated rolls 22, while on the spindle 20, now on the right, will start the formation of a new set of rolls 22.
  • the strips of material 72 now present a direction that is substantially tangent to the cores 44 of the spindle 20 on the right.
  • a cutting station 90 now cuts the strips 72, having predominantly or simultaneously applied a terminal strip.
  • the machine thanks to means of coordination not shown, discharges the terminated rolls 22, removing the relevant spindle 20 from the revolver 24.
  • the turret 50 is first put in rotation so that it rotates round the shaft 52, which can slide in a suitably shaped groove 53.
  • the turret during this operative phase, is not rotated and the machine, by means of means described below, removes the spindle 20 loaded with terminated rolls 22 from the turret.
  • Figs. 5G and 5H illustrate, for the revolver 24, the operative completion phase of the rolls 22 and the cutting phase of the strips of material 72.
  • the machine according to the invention to remove the spindle 20 loaded with rolls 22 from the turret 50, comprises an operative arm 56 which can advance both in horizontal direction backwards and forwards, as indicated by arrow L in fig. 5, and vertically upwards and downwards, as as indicated by arrow M of the same figure.
  • the operative arm 56 is controlled in its horizontal displacements by noted schematized means, e.g. as means with rack 58. Its vertical displacements will be controlled by noted means not shown, e.g. means with piston or similar.
  • means are provided to control the rotations of the spindles 20 in synchroniam with one another.
  • these means comprise a first and second control motor 60 and 62, which are connected to the spindles 20 by means of return kinematisms which carry the movement of rotation of both the first control motor 60 and the second control motor 62 to the axis 64 of one of the spindles 20 whose rotations involve those of the spindles 20, in such a way that, through said kinematisms, the peripheral speeds are identical.
  • One of the spindles 20 will be loaded with rolls of material 22 almost terminated, while the other will be loaded with rolls 22 started.
  • the motors 60 and 62 can be controlled in noted way by means of a card programmer which controls the operation of both motors in order to obtain the abovementioned desired synchronism so that the peripheral speed of the spindles 20 is similar.
  • the material in strip 66 of notable width comes from a return roller 68 and advances, after a further return roller 70, in the direction of arrow N to be cut into strips of prefixed width which are wound on cores 22a, which, traditionally, are prefabricated in cardboard, plastic or similar.
  • the means which cut the strip 66 into thin strips 72 comprise a first plurality of blades 76 carried by suitably shaped means of support 78, which, at one end, are fixed on a supporting shaft 74 carried revolvingly by the casing of the machine which can rotate in the direction of the double arrow Q in fig. 7.
  • the abovementioned first set of blades 76 is in the operative position in which the blades cut the wide strip 66 into thin strips 72, and, in particular, it is noted that cutting takes place on one side of the wide strip 66, which can be defined as external side with respect to same.
  • the perfected machine according to the invention has made it possible to eliminate dead times for replacement of the cutting means, as, as noted in particular in fig. 7, it presents a second plurality of blades 82 carried by means of support 80, which are destined to operatively replace the blades 76 of the first set when the latter are worn.
  • the blades 82 of the second set, now in inactive position, are placed on a second shaft 81 which can be made rotate in the direction of double arrow R of fig. 7.
  • the second shaft 81 is staggered with respect to the first shaft 74 and essentially parallel to it.
  • the second shaft 81 is placed, with respect to the thin strips 72, on the side opposite what may be defined as internal side with respect to same.
  • the above means are identical for each set of blades and comprise a small piston 83 whose shank is movable inside a hollow 89 of the means of support 78 and 80, said shank being provided with a projection 85, engaged in a hollow 87 of the means of support 78 and 80.
  • the width of the hollow 87 is greater than that of the projection 85. In this way, when the blades, e.g. blades 82, are in operative cutting position, the shank 83 is made re-enter in the small piston so that the projection 85 is engaged in a face of the hollow 87 locking the supports 80.
  • a new set of blades is then applied to support 78.
  • the supporting means of the blades will be supported by a corresponding cross-piece and the procedure will be similar, operating the small pistons 83 later when the cross-piece has been removed from the machine.
  • the strip of material of notable width 66 also comes in this case from a return roller 68 and it, being in double layer, is directed to the abovementioned return roller 70 shown in fig. 7 and to another return 84, so that the strip 66 is sent to the upper spindle 20 in the direction of arrow N and to the lower spindle 20 in the direction of arrow T.
  • This part of the machine comprises an operative piston not illustrated, provided for the movement in the direction of double arrow S of fig. 8 of an arm 86, hinged in 88, and a unit for the formation of a new roll of material indicated in the complex with 90.
  • the unit 90 comprises a support 92 whose rotation is controlled by the arm 86, as the abovementioned support 92 is hinged in 94 to the casing of the machine.
  • the support 92 is shown with broken line in the inactive position and with continuous line in the work position.
  • the support 92 will correspondingly be brought to the lowered position in which it is represented with continuous line.
  • a further operative arm 96 hinged in 98 to support 92, which is provided, at one end, with cutting elements 100 to operate on the cores 44 for the start of a new roll of material and for the transversal cutting of the thin strip of material 72 so that it is fixed on the core 44.
  • the second operative arm 96 is provided with means 102, which, pressing the end of the thin strip 72 on the core 44, stretch the latter, causing its peripheral adhesion on core 44 after application with known means, not shown, of a strip.
  • the thin strip 72 has continued its forward movement, thanks also to the rotation of core 44, its end is engaged in cutting element 100 of the operative arm 96 which therefore cuts said end so that the thin strip 72 can be wound on core 44.
  • the cores 44 are visible outside the machine as in this latter there are no mechanisms in movement in front of the feed station of the cores as in traditional machines.
  • the feed station of the cores 44 comprises a feed hopper 104 provided in noted way with a device which makes it possible to arrange the cores 44 in order even if they are inserted haphazardly in the hopper 104.
  • the cores 44 descend, from the hopper 104, into a feed duct 106 by gravity and are superimposed one on the other to be able to be sent one at a time to the station in which the shaft 36 on which they must be loaded is positioned.
  • the means which feed the cores 44, one at a time, to the packaging station of each of the spindles 20, comprise means to temporarily stop one core 44 at a time and permit its feed to the station in which the shaft 36 is placed.
  • the above means which may be connected to a card programmer or similar for sequential operation, comprise deenergizable stops placed on two planes, each corresponding to one of the spindles 20.
  • Fig. 9 shows a detailed schematic view of the unit that permits the feed of one support of the cores, as the other will be identical.
  • the unit to feed the cores one at a time comprises first of all a first de-energizable stop 108 composed of an arm against which a core 44 stops, withheld, on the opposite side, by the side wall of the feed duct 106.
  • the stop 108 is hinged on a small shaft 110, which can be rotated in clockwise direction according to the direction of arrow U so that it permits the fall of core 44 on a further stop 112, also composed of an arm hinged in 114 on its own small control shaft, connected, like the small shaft 110, to means not shown and programmable.
  • the stop arm 112 is longer than the stop arm 108 as it has a different, supplementary function.
  • the arm 112 can, in fact, permit the feed of core 44 and a duct 116 carrying the cores 44 to the relevant loading station, or, alternatively, rotated in the direction of arrow U in fig. 9, permits the further descent of core 44 into a further feed duct 118 to carry the cores 44 towards the other loading unit of the cores.
  • the cores 44 are perfectly aligned in both the ducts 116 which carry them to the loading station 36, and in the vertical ducts 118 fed by hopper 104.
  • Each of the feed ducts of cores 44 to the loading station comprises, along its route, a plurality of de-energizable stops 120, consisting, like stops 108 and 112, of stop arms each hinged on its small control shafts 122 connected to the same programmable means which control operation of the small shafts 110 and 114.
  • the perfected machine according to the invention withholds one pair of cores 44 at a time as there are two stop arms 120.
  • the abovementioned programmable means first free the core 44 placed in the front by means of anticlockwise rotation of the arm 120 associated to it, and, once this arm is returned to stop position, an anticlockwise rotation of the arm 120 will be commanded so that another core 44 goes to the exit end of feed duct 116.
  • the operating cycle of the perfected machine according to the invention can alternatively provide complete feed of the upper duct 116 with consequent filling of the loading station of the cores, associated to upper spindle 20, and, subsequently, complete feed of the loading station of the cores associated to lower spindle 20, or feed of one core 44 at a time for the loading station of the upper and lower cores.
