  • the apparatus according to the present invention for forming/transporting means for closing/opening the mouth of bags - referred to hereinbelow in short as "zipper" - comprises essentiall :
  • the profile 1 is of the type conventional per se and has two parallel strips formed as a shaped male/female head la for relative engagement/disengagement and a flat bottom part lb for joining to the opposite lips of the mouth 5a of a bag 5.
  • Said profile 1 forms overall a so-called "zipper” for repeated closing/opening of the bag mouth.
  • Said drive device 10 comprises a pair of rollers 11 which are respectively rotationally moved by a shaft 11a in turn operated by a motor 13 provided with a device for measuring the revolutions, such as an encoder 13a, able to determine precisely the length of the profile section 1 being fed by the rollers 11;
  • the profile 1 is made to pass through a correspondingly shaped guide 12 so as to keep it stably parallel to the vertical direction Z-Z;
  • Said gripping/transportation device comprises essentially a linear guide 21 which is parallel to the longitudinal direction X-X and on which a sliding shoe 22 of a carriage 23 is movable, the latter having fastened thereto two supports 24 which are able to be displaced in both senses of the vertical direction Z-Z and which carry a gripper 25, the arms 25b of which have a first end hinged at 25a on the support 24 and a free end 25c shaped so as to clamp the shaped head la of the profile 1.
  • the profile 1 is prepared, being wound onto the reel 2 and its end positioned at the entrance to the guide 12 and between the drive rollers 11, - the motor 13 is activated and, controlled by the encoder 13a, determines a speed of the rollers 11 such as to convey a profile section 1, suitably measured, into the vicinity of the gripping grippers 20 which will close around the profile itself;
  • a suitable enable signal will cause operation of the means 15 which cut a measured section of the profile 1;
  • the cut starts the displacement of the carriage 23 from the gripping station SI to the station S2 where the carriage 23 positions the cut profile aligned with the mouth 5a of the bag 5 conveyed to the same station in the transverse direction Y-Y;
  • the possibility of using electronic devices for measuring the length of the profile section 1 to be cut allows variation, in a simple manner, by means of programmable control devices arranged along the line, of the length of said profile section when there is a variation in the longitudinal dimensions of the bag mouth.
  • Figure 6 shows a second example of embodiment of the means 110 for driving a profile 1, which comprise a linear guide 111 which extends in the longitudinal direction X-X and on which a carriage 112 is displaceable, said carriage 112 carrying the jaws 113a of a gripper 113 suitable for closing around the flat part lb of the profile 1, leaving the head la thereof free.
  • the exact measurement of the profile is determined by the measurement of the displacement stroke of the carriage 112 on the linear guide 111.
  • the present invention relates also to a bag filling and sealing machine which comprises an apparatus for forming and transporting means for opening/closing the bag mouth.
  • the machine comprises:
  • a sealing station S comprising means 160 with suction cups 160a arranged on opposite sides of the lips of the mouth 5a of the bag 5; said suction-cup means 160a are able to be displaced symmetrically in the transverse direction Y-Y towards/away from said lips in order to adhere to them and cause relative gripping/opening/closing thereof.
  • Welding bars 120 are arranged underneath the suction-cup gripping means (Fig. 10b) in the vertical direction Z-Z, being in turn arranged symmetrically on opposite sides of the mouth of the bag in the transverse direction Y-Y and being able to be displaced towards/away from the latter.
  • a pair of pressure pieces 130 is present below the welding means 120 in the same vertical direction Z- Z, being symmetrically arranged on opposite sides of the mouth of the bag and being able to be displaced towards/away from said mouth in the transverse direction Y-Y.
  • the machine according to the invention has a further station AC for applying a slider 6 for opening/closing the zipper and applying (Figs. 18- 19) the end-of-travel elements 7 of the slider.
  • Said station AC for applying the slider 6 comprises a gripper 200 able to remove a slider 6 from a store (not shown) , arrange the slider so that it is aligned with the head la of the profile 1 and move in the vertical direction Z-Z from an upper position for supplying the slider to the gripper to a lower position for applying the slider to the head la of the opening/closing profile 1.
  • the same station AC for applying the slider 6 also houses the means 300 for applying the slider end- of-travel elements 7 to the opposite ends of the bag mouth; as shown in Fig. 18, said means 300 may consist of a gripper 300 able to remove the end-of- travel elements 7 from a store and move in both senses of the vertical direction Z-Z from an upper locating position for removing the end-of-travel elements 7 from a store (not shown) to a lower position for applying the end-of-travel elements 7 on the profile 1 for completion of the zipper.
  • the means for applying the end-of-travel elements consist of welding grippers 1300 suitable for performing welds 1007 on the zipper.
  • the measured and cut section of the profile 1 is prepared and conveyed to the station S2 of the apparatus arranged in the machine sealing station S, by means of the carriage 23 of the said apparatus, which is moved along a longitudinal path X-X, and at the same time the filled bag 5 is conveyed to the same sealing station S in a transverse direction Y-Y;
  • the pressure pieces 130 are closed so as to close the bag 5 at a predetermined distance from its mouth 5a in the vertical direction Z-Z;
  • the grippers 25 of the apparatus according to the invention are lowered in the vertical direction Z-Z until the profile 1 is brought into the correct position inside the mouth 5a, so that only the shaped head la remains outside thereof;
  • an automatic filling and sealing machine is able, owing to interaction with the apparatus for cutting and supplying the means for closing/opening the bag mouth, to produce at high speed and at a low cost filled and sealed bags provided with said bag mouth closing/opening means, also avoiding the need for provision of a further specialized machine arranged downstream of the filling machine.
  • the automatic machine may be of the FFS (Forming/Filling/Sealing) type in which the bag is formed from a continuous tubular element or of the type in which the bag is preformed externally to the machine and supplied to the station for filling said bag, via automatic handling means.
  • FFS Forming/Filling/Sealing
  • the machine allows application of the opening/closing means also inside the mouth 105a of pleated bags 105, in this case there being provided gripper means 400 acting on the portions 105b of the pleat.
  • said gripper means 400 are arranged on only one of the two bars 160 supporting the suction cups 160a and on the outside thereof and of the bag 105 in the longitudinal direction X-X; the grippers 400 are movable in both senses of the said longitudinal direction X-X so as to be able to be correctly positioned in the vicinity of the portions 105b of the pleat upon variation in the longitudinal dimension of the mouth 105a of the bag 105.
  • the grippers act symmetrically on one half of the pleat 105b so as to close it in the transverse direction Y-Y and keep open the other half of the pleat into which the profile 1 is vertically introduced, parallel to the longitudinal direction X-X, from where the sequence described above recommences.
  • said gripper means 400 may be alternately arranged on both the bars 160 supporting the suction cups 160a and on the outside thereof and of the bag 105 in the longitudinal direction X-X; the grippers 400 are movable in both senses of the said longitudinal direction X-X so as to be able to be correctly positioned in the vicinity of the portions 105b of the pleat upon variation in the longitudinal dimension of the mouth 105a of the bag 105.
  • the grippers 400 act symmetrically on the opposite and facing portions 105b of the pleat so as to cause closure which is symmetrical with respect to the longitudinal axis X-X of the opposite pleats and introduction of the zipper in a slanting position (Fig. 25) with respect to the longitudinal axis X-X.
