Definitions

  • This Patent covers a bag-filling machine for several products by using a strip-like tubular envelope.
  • These machines are generally automatic, i.e. they prepare the envelope, fill it with the dosed product and seal it so that the package is ready for distribution.
  • the envelope is usually a plastic film.
  • the known bag-filling machines are therefore particularly complicated and expensive, also in view of the fact that when the dimensions of the bag have to be changed serious difficulties arise and various components have to be replaced by others.
  • Some known bag-filling machines also use tubular envelopes, but these bag-filling machines are of the artisan type and not automatic so that the tubular wrapper has to be positioned on the opening for product feeding, according to a technique similar so that frr producing salami and sausages.
  • This Patent is to simplify bag-filling machines while making them more efficient and less expEnsive.
  • This aim is fulfilled by this Patent, by the fact that a commercial tubular tape wrapper is used to create the bags. Utilization of the tubular strip is made possible by an element with special configuration so that it may be suspended inside the tubular strip, thus allowing the strip to advance and all operations necessary for preparing a full bag.
  • This suspended element located inside the strip-like wrapper is supported, according to this Patent, by means of two pairs of idle rolls, a closer pair fixed onto the suspended element and another pair with greater spacing fixed onto a support, in which the roll pair of the element is resting on the roll pair of the support and the tubular envelope is placed between these rolls and can run around the internal suspended element and be positioned for horizontal cutting of the outer face of the wrapper, for sealing of the bottom, filling, sealing of the upper opening and detachment of the full bag.
  • the suspended element 1 is to be placed inside the tubular strip-like envelope 2.
  • This element has a flat bottom, delimited by shaped side edges.
  • the shaping of the edges illustrated in detail has a protruding upper part 3, which expands the tubular strip 2, a recess for positioning of each lateral idler 4, a part 5 virtually an extension of part 3, followed by a recess apt to receive the fixed guide 6 of cutting device 7; which is followed by a raised cusp-shaped section 8, to enlarge the slit 24 cut in the tubular wrapper for filling with the product.
  • the side edges become gradually lower and larger so as to form the two tips of a horn 9, useful to narrow the sides of the bag until they are superimposed for sealing while leaving an air outlet when the package is sealed.
  • the bottom of the suspended element 1 has a slot 10 supporting by means of a bent peduncle 11 the guide 6 of the cutting device 7.
  • the support of the bag-filling machine features a vertical plate 12 sustained by special columns 13.
  • the front face of this plate 12 is provided with two symmetrical idle rolls 14, with a centre distance slightly greater than the centre distance of the rolls 4 of the suspended element 1.
  • Element 1 is supported by its idle rolls 4, which are resting on the rolls 14 of the plate 12 and a front bar 15 or similar component preventing the suspended element 1 from being moved or from falling.
  • This supporting plane 12 is fitted with a cutting component 7, traversing on a guide 16 and moved by cable 17 properly reversed and operated by a double acting oil hydraulic piston 18.
  • the same columns 13 sustaining plate 12 also support in a lower position the double sealing and cutting device .of the filled bag.
  • This device features the cutting and sealing line 19 and the cutting and sealing countsrline 20, in, which the unit is vertically mobile by means of the double acting oil hydraulic pistons 21, from the continuous line position to the dashed line position 19', 20' and viceversa while the cutting and sealing counterline 19 is moved horizontally, by means of the double acting oil hydraulic pistons 22 from the continuous line position 19 to the dashed line position 19' and viceversa.
  • the two sealing lines are astride the cutting line.
  • the tubular envelope 2 passes between the two pairs of rolls 4, 14 and reaches the sealing and cutting line and counterline 19, 20.
  • the transverse dimensions of the tubular strip 2 and the depth of the bag will have to be changed.
  • these various elements 1 having different dimensions can be mounted on the same supporting plate 12, by adjusting the rolls 14 in the horizontal slots 25.
  • Plate 12 and the sealing and cutting device 19, 20 can also be moved vertically along the columns 13 and the stroke of the oil hydraulic pistons 21, which regulate the height of the bags, can be varied accordingly. Procedures as well as the accessories required to vary the dimensions of the bags are therefore simplified.
  • the lower horn-like projections 9 allow for the craation of containers with air-vents at the ends of the upper sealing.
  • the projections 9 will be kept shorter and will not affect the sealing area.
