Definitions

  • the present invention relates to a filling machine of the type pointed out in the preamble of the first claim.
  • the filling machines adapted to produce sealed packages having various contents.
  • the filling machines form a plurality of bags and sachets in sequence starting from a packing sheet and the loose product.
  • a packing sheet is placed close to the machine and starting from this sheet wound up into a reel the bags or sachets will be made.
  • the sheet is unrolled and conveyed to a forming and sealing apparatus.
  • the sheet is wrapped on a tube having a transverse axis relative to the major extension direction of the sheet and a circumference slightly smaller than the sheet width.
  • the advancing sheet portions wrapped along the tube are mutually joined and sealed. It is therefore a seal in the longitudinal direction relative to the major extension direction of the sheet.
  • the longitudinally sealed sheet extends beyond the tube along which it is wrapped and is sealed transversely.
  • the transverse seal is cut in the middle so that the transverse seal acts as head sealing for one bag and bottom sealing for the following bag.
  • the bag that has received the bottom sealing is filled with the product in such a manner that the product remains inside the bag when the head sealing has been carried out.
  • the multitrack filling machines are not adapted to unroll sheets of great overall width, exceeding some tens of centimetres, for example.
  • This drawback is due to the fact that high stresses and friction are created between the sheet and the sheet conveying and driving apparatus so that the tension on the different sheet portions cannot be maintained to a constant level.
  • the multitrack filling machines can only produce sachets of a very reduced width, the so-called "sticks", and in addition a reduced number of tracks in parallel can be provided.
  • a further drawback resides in that the sachets that in parallel come out of the multitrack filling machines are in tight contact with each other. Thus particular sealing or forming elements for the bags cannot be placed close to the multitrack filling machines due exactly to the lack of space between the bags. Under this situation the technical task underlying the present invention is to device a multitrack filling machine capable of substantially obviating the mentioned drawbacks.
  • Another important aim of the invention is to make available a multitrack filling machine provided with particular sealing or forming elements for the bags.
  • the multitrack filling machine is generally identified by reference number 1 .
  • Each packing ribbon 51 defines a longitudinal direction 52 and a transverse direction 53 perpendicular to said longitudinal direction 52.
  • the filling machine 1 is adapted to make closed bags 50 formed with a transverse portion of packing ribbon 51 folded over upon itself in the longitudinal direction 52 in such a manner that two longitudinal flaps 54 of the transverse portion are mutually superposed and sealed and that the lower 55 and upper 56 edges of the bag 50 are mutually sealed, as shown in Fig. 5 .
  • the filling machine 1 briefly comprises conveying means 2 and a plurality of sacking stations 3 each including: forming means 4, sealing means 5, filling means 6, cutting means 7 and driving means 8.
  • the conveying means 2 defines an unrolling trajectory for the packing ribbons 51, in a manner adapted to supply each sacking station 3 with a packing ribbon 51, along an advancing or feeding direction.
  • Said means comprises a reel-unrolling unit 9, preferably structurally independent of the rest of the machine. It is adapted to move reels 58 having large diameters and widths, diameters even exceeding one meter and widths larger than 1.25 metres, for example. Therefore unit 9 is able to provide a long period of self-government by greatly increasing the time intervening between two reel changes, and consequently the efficiency of the machine itself.
  • the reel-unrolling unit 9 preferably comprises a reel-carrying axis 9a actively actuated by a servomotor, operated based on the information of sensors measuring the reel 58 diameter.
  • Unit 9 further comprises a roller assembly 9c consisting of a plurality of movable conveying rollers and adapted to accumulate the packing sheet 57 waiting for processing and to adjust tension thereof.
  • the reel-unrolling unit 9 further comprises longitudinal-cutting knives 9d adapted to longitudinally divide the packing sheet 57 into a plurality of packing ribbons 51, preferably four or six ribbons 51.
  • the reel-unrolling unit 9 finally comprises a pair of opposite powered pulling rollers 9e substantially forming a calender.
  • Said rollers 9e preferably have a high-friction surface, made of elastomer for example, and are adapted to ensure control in conveying the ribbons 51 downstream of the reel-unrolling unit 9.
  • the conveying means 2 further comprises a deviation unit 10, downstream of the reel-unrolling unit 9.
  • the deviation unit 10 comprises deviating devices 10b consisting of rollers or bars oriented at 45° relative to the exit direction of ribbons 51 from the reel-unrolling unit 9 and adapted to deviate ribbons 51 through a right angle.
  • a deviating device 10b is present for each ribbon 51.
  • rollers 10a movable along the unrolling trajectory of the deviated ribbon 51, for fine adjustment of the path length of the packing ribbon 51.
  • the conveying means 2 finally preferably comprises tensioning rollers 11 placed in the vicinity of stations 3. They preferably have an outer surface of high friction, in particular made of elastomer or the like. Furthermore, they are able to detect the tension of ribbon 51, as better specified in the following.
  • the sacking stations 3 Disposed downstream of the conveying means there are the sacking stations 3 preferably of same number as the number of ribbons 51.
  • the sacking stations 3 preferably mainly extend in the vertical direction.
  • the longitudinal direction of ribbon 51 in this portion of the machine 1 is therefore suitably coincident with the vertical direction.
  • Each sacking station 3 first of all comprises forming means 4 for the packing ribbon 51.
  • This means is adapted to fold one transverse portion of one of ribbons 51 along the longitudinal direction 52, in such a manner that the two longitudinal flaps 54 of the transverse portion of ribbon 51 are superposed.
  • the forming means 4 suitably comprises a collar 12 known by itself and consisting of a surface along which ribbon 51 is disposed for running inside a short portion of an underlying tube.
  • Collar 12 is followed by a forming tube 13 around which ribbon 51 is disposed, fully wrapping it in the circumferential direction, leaving the two longitudinal flaps 54 unwrapped around the circumference and mutually opposite.
  • This means comprises a longitudinal sealing device 14 adapted to seal the two superposed longitudinal flaps 54.
  • This device 14 suitably carries out sealing by heat. In particular it comprises a heated portion adapted to be moved by suitable movement means, so as to come into contact with the two flaps 54. It is suitably provided with temperature control and pneumatic movement means, independent for each individual station 3. It can further comprise pulse sealing means, i.e. through electric heating.
  • the sealing means 5 also comprises a transverse sealing device 15 adapted to seal the ribbon 51 in the transverse direction 53 at given longitudinal space intervals.
  • This device 15 suitably carries out sealing by heat supply.
  • it comprises a series of opposite bars, heated preferably by independent heating, disposed after the forming tube 13 and adapted to be moved by suitable movement means, so as to come into contact with the two longitudinally-sealed opposite portions. It is suitably disposed on a single support for all stations 3. It can further comprise pulse sealing means, i.e. through electric heating.
  • Also disposed at the transverse sealing device 15 can be a bag shaping device 50 consisting of a known device for making a square bottom or the like, for example.
  • Stations 3 then comprise filling means 6 ( Fig. 1a ), which means is adapted to fill an open bag with the intended products, i.e. a bag that has been submitted to the longitudinal and transverse seals, the latter constituting the bag bottom, and has the upper portion open.
  • the filling means 6 is known by itself and introduces the products through collar 12 and the forming tube 13.
  • Stations 3 also comprise cutting means 7 downstream of the sealing means 5 of ribbon 51.
  • This means preferably consists of two opposite cutters and divides the bags 50 at the sealing in the transverse direction so that said sealing in the transverse direction constitutes the lower edge 55 of the open bag to be then filled and the upper edge 56 of the bag 50 made in the preceding space interval of ribbon 51.
  • each sacking station 3 advantageously comprises driving means 8 for ribbon 51.
  • This driving means 8 is separated from the sealing means 5 and comprises a dragging surface 16 of high friction, preferably made of elastomer or the like, adapted to interact by contact with ribbon 51 and to drag the latter along in the feeding direction.
  • the driving means 8 is disposed between the forming means 4 and cutting means 7.
  • this means is preferably disposed at the forming tube 13, in such a manner that the dragging surface 16 comes into contact with the ribbon 51 in turn wrapped on tube 13.
  • the driving means 8 is shown in Fig. 4 and preferably consists of crawler tracks 17 driven by wheels 18.
  • the outer surface of the tracks constitutes therefore the dragging surface 16.
  • Tracks 17 preferably have a surface layer of elastomer and more particularly of natural rubber, and a toothed inner layer of stiffer and stronger material.
  • Tracks 17 preferably have width included between 1 cm and 3 cm and are wrapped around an angular portion of the forming tube 13 included between 20° and 30°; their thickness is included between 2 mm and 1 cm and the length is included between 30 cm and 80 cm.
  • each individual station 3 can be further suitably adjusted in an independent manner as a function of the tension of the individual ribbon 51, and each track 17 is preferably set in motion by a single servomotor.
  • the machine 1 further comprises tension sensors 19 for the individual ribbons 51, adapted to check the tension of said individual ribbons 51. They can be disposed at the tensioning rollers 11 for example and consist of sensors adapted to check the vertical displacements of said rollers 11. Alternatively, they can consist of optical reading means or other means known by itself. Operation of a multitrack filling machine 1 described above as to its structure is the following.
  • the machine 1 preferably moves ribbon 51 with alternate pauses.
  • the reel-unrolling unit 9 unrolls a portion of reel 58 and feeds the roller assembly 9c, in turn feeding the remaining portion of the machine 1.
  • Activation of the roller assembly 9c takes place through unrolling of reel 58 by a servomotor moving axis 9c, taking into account the information both from sensors placed on the roller assembly 9c and from a sensor measuring the diameter of reel 58.
  • the packing sheet 57 is then unrolled, separated into ribbons by knives 9d and conveyed to the pulling rollers 9e. Each ribbon corresponds therefore to a track comprising a station 3.
  • unrolling of ribbons 51 is suitably timed with the operations of stations 3.
  • ribbons 51 are moved towards stations 3.
  • the driving means 8 is simultaneously activated on all tracks 3, each crawler track 17 receiving motion from a single servomotor.
  • the pulling rollers 9e are suitably activated by a servomotor.
  • the pulling rollers 9e and driving means 8 are connected in an electric axis so that ribbons 51 are simultaneously dragged along by the roller assembly 9c.
  • the individual ribbons 51 are dragged along, being compensated in position by rollers 10a and deviated by the deviating devices 10b; subsequently they pass through the tensioning rollers 11 and reach stations 3.
  • deviation of ribbons 51 enables stations 3 to be disposed at arbitrary mutual distances. Therefore said stations enable the aforesaid shaping device or driving 8 and sealing devices 15 with said "square bottom" to be introduced.
  • each ribbon 51 enters its own station 3. At each station 3 each ribbon 51 passes through the forming means 4 and takes the shape required for the subsequent sealing step through the sealing 5 and cutting 7 means.
  • tension of the packing material is controlled by adjusting the speed ratio between the driving means 8 and the pulling rollers 9e.
  • Ribbons 51 are therefore stationary, the longitudinal sealing devices 14 are operated by a pneumatic movement for coming into contact with ribbons 51 and carrying out the longitudinal seal.
  • the transverse sealing device 15 is operated by a servomotor for coming into contact with the packing ribbon 51 and carrying out the transverse sealing.
  • the cutting means 7 is driven by the servomotor and carries out the simultaneous cut lengthwise in all stations 3.
  • the measuring process for the product to be packaged by the filling means 6 takes place.
  • the invention comprises a new process for material sacking or for operating multitrack filling machines 1.
  • the process contemplates the above disclosed operation.
  • the invention enables important advantages to be achieved.
  • the quality of bags 50 obtained in the individual stations 3 is ensured by the tension control that is independent in each track.
  • stations 3 can be spaced apart and bulky elements can be introduced, as previously said.
