Definitions

  • the invention relates to structural and functional improvements to the process and machine described in document WO 03/051715 A1 , to which the most extensive reference is made.
  • the process described in the above cited document provides for unwinding the stretchable film from a feed spool, inserting that film in a horizontal mandrel to form a welded leaktight wrapping tube with overlapping longitudinal edges, holding and sealing the forward end of the said tube with jaw means by making two welds and cutting in-between, inserting the product which is to be packed into the inlet opening of the said film-tube-forming mandrel and positioning it at the anterior closed extremity of that tubular packaging which is caused to advance horizontally as an extension of the said forming mandrel by the said anterior jaw and supporting means.
  • the tube wrapping is stopped and decelerated transversely by opposing clamps which clamp it for example at the discharge outlet from the forming mandrel complex, while the said anterior jaw means continue to advance the length of the progressively elongating tubular wrapping so as to stretch it longitudinally by a certain amount, this then shrinking by reaction transversely and adhering closely to the product located within it.
  • the posterior extremity of the stretched packaging is gripped transversely by a second clamping device which forms two transverse welds and a cut between them to seal and hold the rear end of the packaging with the product, while the anterior clamping, welding and cutting device opens, reverses the horizontal movement to return to the cycle start position and leaves the packed product supported on comb means associated with the lower component of the active jaw, welding and cutting device, which holds the end of the new length of tube of film at the outlet from the forming mandrel to repeat a new working cycle as described.
  • rollers is a rubber-coated roller and means which can stop it under control, for example drive means with a brake or an electromagnetic brake, are associated with it, and when this roller is stopped it forms an effective clamp which engages the film transversely and uniformly over its entire length.
  • the longitudinal stretching to which the length of film which has left the forming mandrel is cyclically subjected and within which the tray with the product is positioned uniformly discharges its own energy over the entire length of film between the stretching clamps and the said rubber-coated roller, so that the film itself is not subjected to any appreciable longitudinal displacements which would have an adverse effect on the longitudinal welding means.
  • the machine comprises a forming mandrel 1, of the so-called sling type, which is fixed or possibly adjustable, located in an almost horizontal position, formed by angled parts supported on supports 101 and through which there passes longitudinally a tubular guide 1' supported by external parts 14 which has for example a rectangular cross-section and is such that product P being packed, which is normally intended to be placed in a tray, can pass through it with sufficient play, this being delivered in Indian file by a subjacent feed line 2 of which at least the terminal part is in the form of a comb and acts together with a lifter 3 of matching shape which on command raises the product in line with the end wall of guide 1', whereupon a thruster 4 which discharges the product from the lifter and inserts it into guide 1' operates at the appropriate time, using the working logic described above.
  • 30 indicates known means which determine the dimensions of the product and transmit this information to machine processor 13, which also detects the rate of advance of conveyor 2, all so that the processor can automatically adjust the various working stages of the machine
  • Stretchable thermoplastic film 5 for wrapping the product reaches and is returned from the same extremity of mandrel 1 at which the product enters, being delivered from a spool 105 which is in a sufficiently convenient location for replacement when it is empty, for example above the packaging track, supported on a pair of parallel rollers 6, one of which idles while the other is driven by a drive unit 7 which unwinds the film from that spool.
  • the film unwound from the spool is delivered to a buffer device which includes a set of rollers 108 which are mounted so as to idle on an appendage of supporting structure 9 which also supports said rollers 6 and comprises a set of rollers 8 mounted on a swinging arm 10 pivoted on said structure 9 at 11 and which has a transducer 12 on the pivot which detects the angular position of the swinging arm and converts it into an electrical signal which is used by process unit 13 to control motor 7 so that there is always a sufficient quantity of film in the buffer device to render the film wrapping stage independent of spool 105 from which the film is fed to tube-forming mandrel 1 through the action of a pair of rollers 15, 115 rotatably mounted on an appendage 109 of said structure 9 located above mandrel 1, at an appropriate distance therefrom and for example approximately on the vertical of the discharge opening from that mandrel.
  • First roller 115 idles and is pressed by resilient means 16 towards the other roller 15 which is preferably rubber coated and positioned in relation to the upstream roller and mandrel 1 in such a way that it comes into contact with a suitable contact surface area of film, this roller being positively connected to a motor 17 under electronic speed and phase control, for example a stepping, brushless or other suitable type of motor controlled by processor 13. Suitable means, which are not illustrated, are provided so that roller 115 can be temporarily moved away from roller 15 so that the film can be inserted between them at the start of work.
  • Film 5 runs along mandrel 1 longitudinally in the same direction of advance as product P and through that mandrel is shaped in such a way as to form a tube which envelops tube guide 1', while the edges of the film overlap, for example at the bottom of mandrel 1, where a device 18 of any type, for example a jet of hot air, which welds the said edges together longitudinally with at least one longitudinal weld which is preferably continuous and leak-tight, is in operation.
  • a device 18 of any type for example a jet of hot air, which welds the said edges together longitudinally with at least one longitudinal weld which is preferably continuous and leak-tight, is in operation.
  • the anterior extremity of tube of film 5 leaving mandrel 1 is welded transversely and is held alternately by jaws 19, 119 which clamp it, form two welds and cut between them, comprising two matching and mutually overlapping parts connected to means diagrammatically indicated by arrows 20, 120 and 21, 121 controlled by processor 13, which on command moves them closer together and further apart with a self-centering movement which causes them to move horizontally away from and towards mandrel 1.
  • the lower components of jaws 19, 119 have attached to them on the side opposite that facing mandrel 1 a corresponding projecting plane 22, 122 in the form of a comb.
  • a motor-driven conveyor 23, formed by parallel and horizontal belts, at least in its initial part, through which the tines of planes 22, 122 of jaws 19, 119 can be inserted without interference, are provided at a suitable distance in line with and downstream from mandrel 1.
  • Bars 24, 124 which deliver hot air at the appropriate temperature to the wrapping film leaving the mandrel are located immediately downstream from mandrel 1. These components, which have already been described in the patent cited in the foreword, together with welding device 18 and other components which subject the film or packaging to heat treatment, are also controlled by processor 13.
  • Processor 13 adjusts the cycle described to the dimensions of product P being packed, in particular its length, which is detected through aforesaid means 30 and 2.
  • A indicates the lateral movement of the anterior stretching jaw
  • B the rotational movement of film-feeding unit 15, 115, 17
  • C indicates the sealing movement of the posterior jaw. These movements are inactive in the zero position and are instead active in the top position indicated by 1 in the ordinates.
  • lateral movement A of the anterior jaw begins at the same time as activation of film-feeding unit 15, 115 and the difference in speed between the two movements determines the percentage stretching of the film, which is usually over 100%.
  • motor 17 acts as a brake, or better applies changing friction, controlling the stretching of the film but without causing the latter to stop on forming mandrel 1, with the advantage that it assists the operation of welding unit 18, which can now operate substantially continuously and with the advantage that it prevents film stopping on the mandrel, thus preventing friction on first detachment and consequent local tensions in the film and unsightliness in the packaging, as was on the contrary the case in the prior art.
  • lateral movement A of the jaw ceases in phase with the rotational movement B of rollers 15, 115, but is reactivated in proper phase with sealing movement C of jaw 119 on the tail end of forming packaging Z.
  • rollers 15, 115 and motor 17 continue to feed a little film to the forming mandrel in a controlled way to reduce longitudinal stretching during posterior closure and welding of the said packaging formed, by posterior jaw 119.
  • the quantity of material which is actively delivered during this last stage depends in a directly proportional way on the height of product P, and this is brought about through processor 13 which has determined the dimensions of the product which has to be packed using aforesaid means 30 and 2.
  • motor 17 with controlled speed and phase makes possible easy control of both the position and speed of film feed rollers 15, 115 to ensure that the advance of the film is in phase with respect to the jaw movements through the position adjustment control loop and the difference in linear feed between said feed rollers 15, 115 and the movements of the said jaws through the speed adjustment loop, all in such a way as to ensure good control of film stretching.
  • the example in the diagram in Figure 3 differs from the preceding situation in Figure 2 in that movement B of film feed rollers 15, 115 begins after lateral movement A of the upstream jaw and stops before the said movement A so that the film packaging is stretched by a greater amount and adheres to product P. It is obvious that at the start of the next packaging cycle, when the film has to be unwound for the next pack, the film will be under greater tension.
  • the stopping of movement B activating rollers 15, 115 can be delayed, as illustrated for example in the diagram in Figure 4 , or its start may be brought forward with respect to movements A and/or C of the jaws, as illustrated in the diagram in Figure 5 .
  • the second part of movement B of rollers 15, 115 that which takes place simultaneously with closing movement C of the downstream jaw, is particularly long, for example as in Figure 5 , this has the effect that the film is particularly relaxed at the start of the unwinding cycle.
