Definitions

  • the present invention concerns a method and a machine for packaging different objects, particularly bottles, allowing to obtain a packing meant for hand transport by the buyer.
  • the invention also concerns the portable packing obtained with said method.
  • packings which consist of two intersecting wrapping films of plastic stretching material, one of which - and precisely the wrapping extending in the vertical plane - is meant to form also a gripping handle.
  • These packings are described for example in US-A-4,304,332 and in US-A-4,596,330, as well as in the Italian Patent Application No. 21.483 A/89 in the name of the same Applicant. Nevertheless, the packings described in all these patents still involve at least two drawbacks:
  • the object of the present invention is to therefore propose a packing - of the heretofore mentioned type, formed of two intersecting wrappings, one extending on the horizontal plane and the other on the vertical plane, the vertical wrapping forming also gripping means for the packing, in the form of a handle - which is even more improved in respect of those described in the above indicated patents.
  • a first object of the invention is to provide a packing of the aforecited type, wherein the vertical wrapping, forming the gripping handle, shows improvements both for what concerns the comfort for the hand carrying the packing and for what concerns its transport resistance.
  • a further object of the invention is to obtain a packing of the aforecited type, wherein the vertical wrapping holds more tightly and more reliably onto the group of bottles.
  • the material forming the first strap length so that its characteristics may be particularly suited to form a gripping handle, while the material of the second strap length can be selected so as to have the best properties for adhering onto the block of objects.
  • the first strap length will consist of a flexible plastic material with high tensile strength, such as a polyethylene film having a thickness of 60/70 ⁇ m.
  • the second strap length will consist of a commercial type adhesive tape, of polyvinylchloride (PVC) or polypropylene, applied with its adhesive surface facing upward, so as to adhere to the bottom of the objects, and allow the leading and tail ends of the straps to be joined together by simple adhesion of the ends of the second strap length onto the ends of the first strap length.
  • PVC polyvinylchloride
  • polypropylene polypropylene
  • the packaging method according to the invention is first of all described with reference to figures 1 to 9, showing only a trace of the machine to carry out said method.
  • the working station of said machine, in which the vertical wrapping is formed, is subsequently described in further detail with reference to figure 10.
  • the packaging machine illustrated on the accompanying drawings and described hereinafter is designed for a packing of six bottles. It is however understood that the description of said machine is given by mere way of example and should in no way be interpreted as limiting the protection scope of the invention, which can instead be generally applied to any other type of packaging machine allowing to obtain a packing in the form of two intersecting wrappings consisting of a film of plastic material.
  • a first wrapping extending on a vertical plane is formed on a group of objects to be packaged, particularly a group of six plastic bottles B positioned side-by-side in two rows of three; said wrapping is formed in two parts and, precisely, an upper strap 1 and a lower strap 2, joined together.
  • Figure 2 shows how the two straps 1 and 2 are fed, starting from two respective feed rolls 1a and 2a, to a packaging machine having a sliding surface in the form of rollers 3 and a closing and cutting tool 4.
  • the two straps 1 and 2 are joined together by their ends, in U.
  • This connection is obtained by glueing, thermowelding, or the like, as better specified hereinafter.
  • the upper strap 1 of said first wrapping preferably consists of a film of flexible plastic material, as for instance polyethylene, having a thickness of 60/70 ⁇ m.
  • the lower strap 2 is instead an adhesive tape of commercial type, for example a polyvinylchloride (PVC) or polypropylene tape with one of the surfaces having a layer of adhesive substance.
  • PVC polyvinylchloride
  • polypropylene tape with one of the surfaces having a layer of adhesive substance.
  • the lower strap 2 it is of course possible for the lower strap 2 to be equally formed of a polyethylene film - like the upper strap - and to be anchored onto the strap 1 by glueing or thermowelding.
  • the tool 4 will obviously be provided with thermowelding means.
  • the packaging method then provides for a further step wherein a second wrapping is formed, using a strap which extends on the horizontal plane, as shown in figure 5.
  • Said second wrapping 5 consists of a film of plastic stretching material - as PVC, EVA (ethylvinylacetate), LPDE (low density polyethylene) and, above all, LLPDE (low density linear polyethylene) - wound into several turns over the first wrapping 1-2.
  • This second wrapping is applied under slight tension, so as to positively block in position both the packed objects and the vertical wrapping.
  • Figure 6 shows how the second wrapping 5 keeps the first wrapping 1-2 strongly tightened against the lateral surface of the bottles, and thus forms an integrating part of the packing. Practical tests have shown that this tightening action is sufficient to keep fastened the strap 1 of the first wrapping even if the strap 2, and thus the respective anchorage, should be missing.
  • a gripping handle 6 is formed by gathering up the strap 1 at the top of the vertical wrapping.
  • FIG 10 which, as said, shows in further detail the working station in which the vertical wrapping is formed - it can be seen that the bottles B1, sent from a bottling line and advancing in a vertical position onto a sliding surface - for instance the already mentioned rollers 3, or a horizontal belt conveyor (not shown) - are divided into groups of six, each group being stopped in succession in the different working stations of the packaging machine, and precisely the stations supporting the groups of bottles B1A, B1B, B1C and respectively B1D (of which only station B1B is shown to form the vertical wrapping).
  • the lower strap 2 - preferably, as said, an adhesive tape - is unwound from a feed roll 2a, by way of a motored unwinding roller 9, and is fed onto the horizontal sliding plane of the bottles with its adhesive surface facing upward, so as to come into contact with the bottom of the bottles B1B.
  • the upper strap 1 - preferably, as said, a film of strong and flexible plastic material, of the PVC or polypropylene type - is unwound from a feed roll 1a and moves first of all across a set of driving rollers 10, meant to develop a length of film so as to facilitate unwinding, and subsequently across a cutting and applying head 11, movably mounted along vertical guides (not shown).
  • the head 11 is formed of a stiff body, ending at the bottom with an oblique surface 11a.
  • a cutter 12, to cut the strap, is fixed on the side opposite to the surface 11a.
  • a sliding block 13 is moreover positioned against the cutter 12 for protection thereof, said block being mounted vertically slidable - against the action of spring means 14 - between a lowered position protecting the cutter 12 (shown in figure 10) and a raised position in which the cutter is free to cut the straps 1 and 2 (as better described hereinafter).
  • the sliding block 13 has in turn an oblique surface 13a, opposite to the surface 11a and forming therewith a kind of wedge.
  • a counterhead unit is mounted beneath the horizontal sliding plane of the bottles, said unit consisting of a U clip 17 mounted on a support 18 moving vertically under the action of a piston 19.
  • the clip 17 is formed of a flat spring, the arms of which tend to open wide apart due to elasticity and, in a rest position, they bear onto a pair of fixedly mounted guide bars 20.
  • the head 11 When the vertical wrapping is formed in the working station B1B, the head 11 is moved down from the rest position shown in figure 10, in the direction of the arrow F3, carrying with it the strap 1 down to the position indicated by the dash-and-dot line 1′. As can be seen from the drawing, the strap 1 bends at the bottom taking up a wedge profile, which corresponds to its bearing onto the oblique surfaces 11a of the head 11 and 13a of the sliding block 13.
  • the sliding block 13 is raised, leaving the cutter 12 free to cut the strap 1.
  • the two strap ends, thus cut, move away from the surfaces 11a and 13a, and are applied - for example by an air jet blown by nozzles (not shown) -against the side of the bottles of the group B1B and, respectively, against a bearing plate 11′ fixed to the body of the head 11 (said bearing plate 11′ being at this stage adherent to the side of the bottles of the group B1A).
  • the support 18 is moved upward together with the clip 17, the arms of which press first of all the strap 2 against the cutter 12, up to causing its cutting.
  • the clip 17 moves up even further, its arms, being released from the bars 20, then open elastically wide apart and press the cut ends of the strap 2 against the side of the bottles B1B and, respectively, against the plate 11′, that is, over the ends of the strap 1 (which were already bearing on said surfaces) onto which they stick.
  • This application of the adhesive surface of the strap 2 onto the strap 1 produces a permanent connection between the two straps: this allows to close the vertical wrapping on the side of the group of bottles B1B, and to form the initial junction for a new wrapping - like the U junction on the group of bottles B1B - on the side of the group of bottles B1A.
  • the bottles can thus be moved forward towards the third working station, taking up the position of the group of bottles B1C, while their place is taken by the group of bottles B1A positioned further upstream, which, in its forward motion, draws the required length of reciprocally joined straps 1 and 2, as described with reference to figure 3.
