Definitions

  • the invention relates to the technical sector of automatic machines for packing loose products in envelopes made of soft materials, also known by experts in the sector as stick-packs.
  • liquids are inserted into these envelopes, or moreor-less viscous liquid solutions, pastes, granular substances or powder substances, etc.
  • the tubular package is made to descend in a step-advancement, the step corresponding to the desired length of each single envelope, and is welded along the vertical edges, specially superposed, as well as transversally welded in accordance with the above-mentioned step, to divide the internal volume of an envelope from the internal volume of the overlying tubular package, in phase relation with the action of the dispensing means to insert, in each of the envelopes, a batched quantity of product.
  • a sort of a string is produced, constituted in the upper part by the continuous tubular package and in the lower part by a certain number of full envelopes arranged in a line.
  • the cut envelopes are released by force of gravity onto a slid or a conveyor belt which removes them; in other embodiments handling organs are included, for example of the pick and place type, or anthropomorphic organs, which remove each single cut envelope and deposits it in a predetermined downstream position.
  • the step-advancement of the tubular package 1 the transversal welding of the package 1 for the definition of the package 10, and the shearing-off of the package 1 are performed by a single operating group G, in which the welding heads 21, 22, once locked on the tubular package 1, are translated downwards by a step P, thus also functioning as drawing organs; cutters 30, housed in the welding heads 21, 22, are activated in step relation with the bottom dead centre, for cutting off the envelope 10.
  • the cutter 30 must have saw-toothed blades which give a jagged cut (not illustrated), obtained by cutting the material of the envelopes 10.
  • the cutters 30 are positioned externally of the group G comprising the welding and drawing heads 21, 22; for a straight cut, a blade 31 has to work in opposition to a counter-blade 32, which cannot be in direct contact with the welding heads 21, 22 in order to prevent deformations caused by the heat of the welding heads 21, 22, with the consequent possibility of malfunctioning.
  • the cutting station ST is positioned below the welding heads 21, 22 by at least a step lower with respect to the bottom dead centre reached by the welding heads 21, 22 during the drawing.
  • the outlet station SU of the full envelopes 10 is in an inferior position, with a vertical development which depends on the size of the discharge organs of the envelopes 10; the consequent increase of size in terms of height, which the solution with the straight cutters incurs, has an effect on the positioning height of the folder and the further organs situated in the upper part of the machine, among which the product batching group.
  • the envelopes realised using the above machines are widely used in the food sector (for example for sugar sachets) and also in the cosmetic field, while they are not yet very widely used in the pharmaceutical field, although interest in them in that field is on the increase.
  • the characteristics of the material the envelopes are made of varies; in particular, for the pharmaceutical sector, the use of resistant materials is required, which must be nontoxic and which must guarantee a perfectly hermetic weld.
  • the aim of the present invention is therefore to provide a machine for packing products in envelopes conformed such as to obviate the above-mentioned drawbacks, in particular to contain the size in terms of height and to be adaptable to sawtooth cutters or blade-counterblade cutters for either jagged or straight cuts.
  • a further aim of the invention consists in providing a machine in which the line of envelopes formed, before arriving in the cutting zone, is not excessively long such that the segment of the string which is momentarily lacking in a guide is as short as possible.
  • a still further aim of the invention relates to the will to contain to a minimum the contact time of the welding heads with the envelopes, such as not to cause heating of the product and thus render the machine suitable also for use in the pharmaceutical sector.
  • the machine of the present invention exhibits, in its entirety, a vertically-developing configuration, with the folder located high up and the outlet of the full envelopes in the lower zone, similarly to known-type machines.
  • FIG. 3A, 3B and 3C relating to the present machine, a schematic illustration is made of only the zone in which the envelopes are formed and cut, as in figures 1A , 2B and 2C and 2A, 2B and 2C , which illustrate the corresponding zones of known machines, such that the advantages provided by the solution of the invention will be evident.
  • 1 denotes a continuous tubular package, developing vertically from the top downwards, obtained starting from a continuous sheet unwinding from a reel and guided to fold upon itself by the folder means.
  • the vertical edges of the continuous tubular package 1 are superposed and stably joined by first welding organs, not illustrated as of known type; the package 1 is then moved downwards in steps P corresponding to the length of the envelopes 10 which are to be obtained, as described herein below.
  • the machine of the invention comprises a first station S1 below the folder, a second station S2 below the first station S1 and drawing organs 40, for the step-descent of the continuous tubular package 1.
  • Welding organs 20 are provided in the first station S1, which welding organs 20 act transversally of the continuous tubular package 1, defining consecutive envelopes 10; during operation, the action of the second welding organs 20 is to separate the internal volume of the underlying envelope 10, which in this way is sealed, from the internal volume of the overlying tubular package 1 and, at the same time, the bottom of the new envelope 10 being formed is closed.
  • the "string" as mentioned above is formed, constituted in the upper part by the continuous tubular package 1 and, in the lower part, by a certain numbers of full envelopes 10 arranged in a row; in the example shown in the figures, the number of envelopes 10 varies from one to two, apart from the one under formation, as specified herein below.
  • the second welding organs 20 are constituted, for example, by two opposite heat-welding heads 21, 22 which are horizontally mobile between an inoperative open position X1 and an operative closed position X2, by the action of actuator means (not illustrated), activated in phase relation with the pause of the continuous tubular package 1.
  • each envelope 10 Before being closed, each envelope 10 receives a batched quantity of liquid product, in a paste form or granular form, or powder form, by means of known dispensing means (not illustrated), partially inserted in the tubular package 1 in the zone comprised between the folder and the first welding organs.
  • the dispensing means are activated in phase relation with the closure of the heads 21, 22, such that the product introduced is located by force of gravity on the bottom of the envelope under formation.
  • Cutting organs 30 are located in the second station S2, which cutting organs 30 separate the envelope 10* which (in turn with the others) occupies the lowest position in the line, from the envelopes 10 located above the lowest one; the cutting operation, done in known way, is performed at about halfway up the heat-welded strip of the heads 21, 22.
  • the cutting organs 30 comprise, in a first example shown in the figures, cutters for straight cutting constituted by a blade 31 and a counter-blade 32, activated in opposition thereto, with a horizontal movement impressed by relative actuator means (not illustrated), between an inoperative open position K1 and an operative closed position K2, in phase relation with the pause of the continuous tubular package.
  • the drawing organs 40 grip the lower flap 10A of the envelope 10* situated at the lower end of the line, when the envelope 10* is in the second station S2 in order to determine a descent by one step P of the line and the continuous tubular package 1, in phase relation with the inoperative open positions of the first and the second welding organs 20 as well as the cutting organs 30.
  • organs 40 in a preferred embodiment, comprise a vertically-mobile group 41, at a top of which pliers 42 are associated, jaws of which face upwards towards the lower flap 10A.
  • the group 41 and the pliers 42 are activated, in phase relation, by relative actuator means, not illustrated, which define, for the group 41, a run between a raised position A and a lowered position B and vice versa and, for the pliers 42, a closed gripping configuration C and an open release position R.
  • the raised position A is regulated such that the pliers 42 advance the cutting line T of the cutters 31, 32 to the second station S2, while the lowered position B is fixed at a level at which the run corresponds to the predetermined step P, i.e. the length of an envelope 10.
  • Figure 3A illustrates the stage at which the tubular package 1 and the underlying consecutive envelopes 10 are paused, with the group 41 lowered in the relative position B and the pliers 42 open in the release configuration R.
  • the heat-welding heads 21, 22 present in the first station S1 are in the respective closed operating position X2 to complete the sealing of the immediately-underlying envelope 10 and realise the closing of the bottom of the overlying new envelope 10 under formation.
  • the cutters 31, 32 are in the relative closing operating position K2 in order to cut the final envelope 10* of the line from the immediately-overlying one.
  • the last envelope 10* can be gripped by sucker organs 50, associated to a known handler, such as is illustrated, or alternatively, can be left to fall towards a slide (not illustrated).
  • Figure 3B illustrates the stage in which both the heat-welding heads 21, 22 and the cutters 31, 32 are open in the respective inoperative position K1, X1, while the group 41 has lifted into the raised position A and the pliers 42, in phase relation, have been closed in the gripping configuration C to grip the lower flap 10A of the last envelope 10*.
  • Figure 3C illustrates the stage at which both the heat-welding heads 21, 22 and the cutters 31, 32 are still opening the respective inoperative position K1, X1 thereof, while the group 41 has descended into the lowered position B thereof, with the pliers 42 closed, drawing downwards, by a step P, the last envelope 10* and the tubular package 1.
  • a further positive characteristic of the machine relates to the versatility offered by the fact that it can be equipped with either saw-tooth cutters or blade-counterblade cutters, respectively for jagged cuts or straight cuts, differently to the known solution of figures 1A, 1B, 1C and 1D .
  • a further characteristic, consequent to using a string drawing system which is separate from the welding heads, consists in obtaining a minimum contact time of the welding heads with the envelopes, thus preventing product heating and, therefore, rendering the machine perfectly suitable for use in the pharmaceutical sector.
