Definitions

  • the invention relates to a film feeding and cutting group applicable on automatic product conditioning machines.
  • Automatic machines of this type have a work line comprising known intermediate positioning stations and packing stations for groups of products in plastic envelopes (downstream of the machine).
  • the intermediate positioning stations have the task of defining, in terms of numbers, pre-established groups of products (varying according to the packing which is to be done) and of transporting said products towards the above-mentioned packing stations at the end of which the product group (or part of it) leaves the station itself and passes into the transport station, which is in its turn provided with a mobile lower belt which enables the products to reach the wrapping station.
  • the product wrapping stations are equipped with a feeding system for film in bobbins (said film will be used to make the above-mentioned envelopes), which film is of thermo-retractable plastic material, and which bobbins are situated in an appropriate station below the level of the product conveyor belt; said station carries the film, by means of an appropriate inclined belt moving in the same direction as the advancement direction of the product, up to the level of the said product conveyor belt.
  • the film feeding station is equipped with a cutting device, positioned upstream of the film conveyor belt, which comprises a mobile rotating knife, said knife being positioned transversally with respect to the direction of said film and said knife being as long as the film is wide; said knife is phased with the rest of the production line and permits of the cutting off of sections, of predeterminable length, of the film, said lengths being those required for the packing of the products.
  • a cutting device positioned upstream of the film conveyor belt, which comprises a mobile rotating knife, said knife being positioned transversally with respect to the direction of said film and said knife being as long as the film is wide; said knife is phased with the rest of the production line and permits of the cutting off of sections, of predeterminable length, of the film, said lengths being those required for the packing of the products.
  • the knife is activated by means of motorisation, having a bracking and friction device which device makes it possible, in co-operation with a series of cogged wheels, to stop the knife in a non-interfering position with respect to the film direction line, and then to activate it, phasing it with the length of the film to be cut, and finally to cause it to make a round angle at each operation;
  • said type of intermittent-cyclic movement can bring about anomalies and irregularities in the functioning of the various movement components of the cutting stations and furthermore decisively limits the operativity of the knife at high speeds; to add to this, the most negative aspect consists in the high costs attached to such operations, with consequent limitations where high category machines are concerned.
  • Aim of the present invention is to realise a cutting group for heat-weldable film, in successive equal lengths, having continuous movement so as to provide a cutting device which is of moderate and for this reason applicable to lower performance but functionally effective machines.
  • the invention reaches the said aims by providing a feeding and cutting group equipped with support and movement means for a knife comprising a chain pair parallel to and facing one another, closed around a first cogged wheel pair of which one is motorised and phased with the machine; said chain pair bilaterally and rigidly supports the knife in such a way as to permit of its continuous movement, through a virtually circular cycle, so as to bring said knife into a position of interference, perpendicular to a first conveyor belt and in the same plane as said conveyor belt and therefore into a cutting position with respect to a length of film, at a velocity superior to that of the advancement of said film.
  • the feeding and cutting group (denoted in its totality by 1) is applicable to machines dedicated to the transport and packing of groups of products; said feeding and cutting group 1 comprises: a roller 2 for plastic film M, supported by a support structure 3 for the machine, and arranged upstream of a first conveyor belt 4 for the same film M.
  • the conveyor belt 4 carries the film M at an advancement velocity V which is predetermined and phased with the machine, and said conveyor belt 4 is arranged below a second conveyor belt 5, which conveyor belt 5 is motorised by a principal geared motor 25, and which conveyor belt 5 feeds a packing station 6 (not illustrated since it does not form the part of the present invention); immediately upstream of the conveyor belt 4 and downstream of the first roller pair 16 and 17, two pairs of rollers 18 and 19 are envisaged in succession, which rollers 18 and 19 are mounted to the support structure 3 of the machine.
  • Each roller pair 18 and 19 has one roller mounted above the other in such a way that the unrolling film M is invited to move towards the conveyor belt 4; preferably the lower rollers 19 are smooth and made of metal, whereas preferably the upper rollers 18 are rubberised and exhibit circumferential grooves 18a wherein are housed extraction fingers 20 supported on cross-supports 21.
  • the said cross-supports 21 also supports the upper rollers 18 and 19 by means of pivots 22 around which pivots 22 respective springs 23 are coiled, which springs 23 are regulatable in compression. Said springs 23 have the function of maintaining the said upper rollers 18 in a lowered position.
  • the conveyor belt 4 is kinematically connected to the above-mentioned principal geared motor 25 by a link 26 which link 26 defines a discontinuous rotating movement of the conveyor belt 4 with differentiated velocities so as to permit of distancing two successive lengths S of film M; correspondingly, one said rollers 18 and 19 from the downstream pair nearest to the first conveyor belt 4 is motorised by the principal geared motor 25 (by means of a chain 28) at a velocity which is greater than that of the preceding roller pair in such a way as to define a tension of the film M which will permit of its precise cutting (thanks to the fact that the film is thermo-retractable and can thus undergo deformations of this kind).
  • the feeding and cutting group 1 is equipped with a knife 7 (constituted in the example by a shaft 7a to which a saw blade is connected), which is equipped with means (denoted by 8 in the figures) of support and movement phased with the machine, and which is interpositioned between the above-described second roller pairs 18 and 19 in such a way as to define the lengths S of plastic film M, of predeterminable length in movement before it passes definitively on to the conveyor belt 4.
  • a knife 7 constituted in the example by a shaft 7a to which a saw blade is connected
  • means denoteted by 8 in the figures
  • the means of support and movement 8 of the knife 7 comprise a chain pair 9, parallel and facing one another, and closed around a corresponding first cogged wheel pair 10 and 11 of which one cogged wheel is motorised and phased with the machine, while both are supported by a corresponding lateral wall which wall is part of the support structure 3;
  • the chain pair 9 supports rigidly and bilaterally the knife 7 and envisages that one of the cogged wheels, the one denoted by 10 in figure 1, is motorised and connected to the principal geared motor 25 by means of a corresponding chain 27.
  • a second driven cogged wheel 14 is interpositioned between this first cogged wheel pair 10 and 11.
  • a perpendicular cutting-block 15 may be envisaged in correspondence with the rollers 18 and 19; said cutting-block 15 is arranged transversally with respect to the first conveyor belt 4 and upstream of said conveyor belt 4 in such a way as to co-operate with the knife 7, by lifting the film M slightly at the point of cutting.
  • the conveyor belt 4 is subdivised into two contacting halves 4a and 4b, so as to realise a single passage plane for said film M, while at the same time providing differently and oppositely inclined halves with respect to the conveyor belt 5 and being arranged in such a way as to transport the film M in an advancement direction (indicated by arrow A in fig.1) opposite to the advancement direction of the conveyor belt 5 (indicated by arrow B in fig. 1).
  • the cogged wheels 10 and 11 and the chains 9 permit of a continuous movement of the knife 7, through a path which is virtually circular, so as to bring the said knife 7, cyclically, into a position of interference, perpendicular to the first conveyor belt 4 (visible in fig. 1) and in correspondence with said conveyor belt 4; at this point the knife 7, co-operating with the cutting-block 15 which lifts a section of the film M, performs the cutting of the film M, at a velocity V1, at the point of the film M lifted by the said cutting-block 15, faster at that point than the velocity V of advancement of the film M.
  • the lengths S of the film can be varied by increasing or decreasing the advancement velocity of the film, but in order to obtain a perfect cut it is necessary to maintain the film velocity lower than the knife 7 velocity.
  • the stopping of the knife 7, for the changing of the size of the lengths S or when the reel of film M finishes, means that the entire group, including the first transport station, must be arrested.
