Definitions

  • ABSTRACT Transversal seals are protected during the continuous formation of packaging containers by a longitudinally sealed hose of packaging material which is transversally sealed and thereafter cut thru said seal, whereby the hose is clamped above the seal during the application of said seal and is maintained clamped while travelling from the sealing means to the cutting means.
  • the invention refers to a procedure and a device which is applicable to packaging machines which produce liquid containers from a continuous web of packaging material, and has the object of protecting the transversal seals simultaneously with their formation till they have sufficiently cooled to resist the pressure of the liquid column overlying them.
  • the web of packaging material is formed into a continuous hose by longitudinally welding together its margins.
  • the liquid contents are filled into this hose at a filling station of said machines, and thereafter the hose is divided into single containers by heat-sealing it transversally at desired intervals and cutting these transversal seals along their centerlines.
  • This transversal sealing constitutes a problem.
  • the jaws which apply said transversal seals fail to grip the seal for a time sufficient to let it cool, said seal will not acquire a strength sufficient to withstand the pressure of the liquid head overlying it, and consequently it is liable to yield or tear.
  • they retain their grip on the hose till the transversal seal has cooled the production rate of the machine will be considerably reduced.
  • the present invention solves this problem by providing clamp means which, simultaneously with the application to the hose of a transversal seal by the sealing jaws, grip the hose along a line above said transversal seal, thereby excluding the seal from the contact and the pressure of the liquid in the overlying hose portion. They continue to grip the hose during its travel from the sealing to the cutting station, and release it when the transversal seal is again firmly held between the cutting jaws.
  • the transversal seals applied to the hose of packaging material are therefore never subjected to the pressure ofthe overly ing liquid column, since this is excluded by the clamping means from the moment of their application till the moment where the knives of the cutting jaws cut the seal along their centerlines, i.e. during a time interval which permits the seals to cool and thus acquire their full strength.
  • the invention markedly speeds up the production rate of packaging machines, because the sealing jaws may now open and let the hose proceed immediately after they have applied the transversal seals, and similarly the liquid article to be packaged can be filled into the hose simultaneously with the downward motion of the latter, whereby the filling ofthe hose as an extra operating step is eliminated.
  • FIGS. 1 to 4 show in a vertical section, as many operating steps of a complete working cycle of the embodiment
  • FIG. 5 is an enlarged schematic partial view of the right hand side of FIG. 4;
  • FIG. 6 is a schematic top view of FIG. 5;
  • FIG. 7 is a schematic top view along line VII-VII of FIG. 1;
  • FIG. 8 is a partial vertical section of the cutting jaws of the device.
  • FIG. 9 is a schematic top view of FIG. 8.
  • the hose 62 formed, as known, from a web of packaging material by longitudinally sealing together its margins, receives a first transversal seal by the horizontally reciprocable sealing jaws 39 and 40 and is thereafter filled with the liquid article 65 through a filling tube 64.
  • the containers areformed from said hose by applying to it transversal seals at desired intervals and separating them by cutting said transversal seals along their centerlines. These cuts are made by cutting jaws, such as the cutting jaws 42 and 43.
  • the sealing; jaws 39 and 40 are supported in 41, the cutting jaws in 44.
  • the metering or dosage chamber comprising two lateral plates 45 and 46, placed at both sides of the hose. The distance between them corresponds to the width to which the portion of hose which has penetrated in said chamber during its downward path will be allowed to expand.
  • Two vertically displaceable wedges 47 and 48 respectively, one on each internal face of said plates, serve to change the volume of said chamber and thus to meter the liquid going into each container 66.
  • a first group of crosspieces is fastened at equal intervals to a pair of revolving endless chains or belts I, 2 on the right side (as seen in FIGS. 1-4) of hose 62.
  • a second group of crosspieces is fastened, at identical intervals, on a similar pair of chains 3, 4 revolving in an opposite direction on the left side of hose 62.
  • Each crosspiece of one group coacts with one crosspiece of the second group to form clamp means.
  • three pairs of coacting crosspieces are shown, namely 5 and Si; 6 and 9; l0 and 7.
  • Each pair such as pairs 7 and I0, clamps lightly the hose 62 just above the level at which the transversal seal is applied, thus protecting it from the pressure of the overlying liquid 65 in hose 62.
  • the clamp means follow the hose in its descending motion till the transversal seal is again caught between the cutting jaws 42, 43.
  • this seal is protected by the pairs of crosspieces practically till it has cooled sufficiently to acquire its full strength.
  • the chain pair 1, 2 revolves around drive sprockets 11, I2 actuated, by not shown means, over a common shaft 13 and supported on brackets l4, l5 fastened to the frame I6, 17; and passes over guide bars 22, 23 hinged to the frame at 24, 25 to swing from the position shown in FIGS. 1 and 4 to that of FIGS. 2 and 3. Thence the chain pairs move over guide sprockets 20, 21, and l8, 19 back to drive sprockets I], I2 to resume its cycle.
  • the second chain pair 3, 4 is driven in synchronism with the first one around sprockets 26, 27, guide bars 35, 36, and guide sprockets 33, 34 and 31, 32.
  • Two endless belts 49 and 50 are positioned above the sealing station. They are tensioned and revolve between pairs of rolls or pulleys 51, 52 and 53, 54 respectively for the purpose of preventing the lateral expansion of hose 62 before it reaches the metering chamber.
  • the sealing jaws 39, 40 have applied a transversal seal 67 to the container 66 positioned in the metering chamber.
  • Guide bars 22, 23 and 35, 36 have swung towards each other to cause the crosspieces 7 and to clamp hose 62 immediately above the transversal seal 67.
  • the cutting jaws 42 and 43 are open.
  • the transversal seal is cut along its center-line by the knife 57 (FIGS. 8 and 9), while it is still gripped by jaws 42 and 43.
  • a refrigerant liquid is circulated within the conduits 60 and 61 provided in said jaws, which keep their hold on the transversal seal 67 and open when, after the application of an upper transversal seal to the container 69 enclosed in the metering chamber, chain pairs 1, 2 and 3, 4 respectively and consequently also the crosspiece pair 6 and 9 resume their motion and thus the successive operating cycle begins.
  • a special type of cutting jaws has been developed. As can be better seen in FIGS.
  • one jaw indicated at 43, presents a longitudinal horizontal slot 55 within which a knife 57 mounted on a slider 56 can be reciprocated by a rod 58.
  • the other jaw 42 is provided with a matching groove 59, into which said knife projects when the cutting jaws are closed.
  • the improvement comprises the steps of clamping said hose during the application of a transversal seal along a line spaced above said transversal seal, maintaining said clamping action during a pair of travel of said seal from a pair of sealing jaws to the cutting jaws, and releasing the clamping action after the seal is gripped between said cutting jaws.
  • an apparatus for forming, filling and sealing tubular packages and improved device for the protection of the transversal seals during the formation of packaging containers by transversally sealing a longitudinally sealed hose of packaging material said device comprising: sealing jaws for applying a transversal seal, cutting jaws for gripping and cutting said seal, clamping means for gripping said hose along a line spaced above said transversal seal, wherein the improvement comprises the means for maintaining said clamping means gripping said hose during the travel of said seal from said sealing jaws to said cutting jaws and to release said clamping means when the transversal seal is gripped by said cutting jaws.
  • said clam ping means comprise two groups of crosspieces, each crosspiece of one group coacting with one crosspiece of the second group to form a pair of clamps, the crosspieces of each pair gripping the hose between them above the level at which said transversal seal is being applied and following the hose in its motion until said transversal seal is gripped by said cutting jaws, thereby protecting said transversal sea] from the pressure of the overlying liquid column in the hose during said travel.
  • a device wherein the crosspieces of each group are fastened between two revolving endless chains and guide bars for guiding said crosspieces towards the corresponding crosspieces of the other group into said hose-clamping relationship, said guide bars being swingable from an open position receiving said crosspieces to a closed position in which they press said crosspieces from both sides against said hose above the level of said transversal seal.
  • a device further comprising guide means extending from below said guide bars to a level above said cutting jaws to guide said pairs of crosspieces from the lower end of said guide bars to a level above said cutting jaws in a hose clamping relationship.
  • a device further comprising a metering chamber for metering the volume of the liquid going into each container, said metering chamber extending between said sealing jaws and said cutting jaws and comprising two lateral plates located at both sides of the hose and two wedges, one at each internal face of each said plate, each wedge being vertically displaceable to adjust said volume.
  • one of said cutting jaws comprises a horizontal longitudinal slot and a seal-cutting knife reciprocable within said slot, while the other cutting jaw comprises a groove matching said slot, into which said knife projects when said cutting jaws are closed, said cutting jaws being additionally provided with conduits for the circulation of a cooling liquid within them.
