Definitions

  • the present invention relates to a method and an apparatus for closing a packing tube wrapped around an essentially cylindrical packaged product, in particular a tampon for feminine hygiene.
  • packing tubes are made of a flexible, typically heat-sealable film which is first arranged in tube shape around the packaged product in a way such that a forward packing tube portion, still open, projects beyond the free forward end of the packaged product.
  • US Patent No. 4 583 964 describes a gripping mechanism which clamps the forward end portion of the packing tube around a shaft introduced into the open forward end.
  • the gripping mechanism has clamping jaws which are closed against the shaft with the projecting forward end of the packaging tube gripped inbetween.
  • the gripped forward end portion of the packing tube is then rotated with respect to the winding spindle and the packing tube held thereon, in order to form a twist with a twist rosette and a twist neck.
  • the clamping mechanism is opened and withdrawn, and a pressing head having a recess complementary to the forward end of the winding spindle is advanced against the twist and the winding spindle.
  • the cylindrical outer edge of the twist rosette is thereby folded and finally pressed against the outer surface of the packing tube when the pressing head with its recess has completely received the forward end of the packing tube on the winding spindle.
  • the inner walls surrounding the recess of the pressing head are heated in order to melt the twist and to join the film material of the twist rosette with the film of the packing tube.
  • a pressing head is then used in order to fold the twist and the twist rosette onto the forward end portion of the packing tube around the tampon and to heat-seal the film material in order to form a dome-shaped packing closure over the tampon tip.
  • a rather long portion of the packing tube has to project beyond the forward end of the inserted tampon in order to allow that a front end of this projecting portion is gripped and that a twist is formed between the gripped portion and the tip of the tampon.
  • a rather high amount of packing film in the open, forward projecting end portion is needed for the sole purpose of closing the packing tube, and thus the packing film consumption of the known method is rather high.
  • a typical packing film material used in the known methods is cellulose hydrate or regenerated cellulose (known under the trade mark CELLOPHAN). It would be desirable to use other film materials, as for example polypropylene. Unfortunately, most, if not all, forms of polypropylene film are not suitable to be closed by the above described twisting methods.
  • a front portion of the open, forward projecting packing tube portion is pressed together and joined by clamping jaws to form a film sheet.
  • This joining or closing to a film sheet can be done by heat-sealing, if a heat-sealable film material is used, or by pressing, if the film material used has, at least in the area of the forward projecting end, a coating of a pressure sensitive adhesive.
  • the film sheet is then folded over and laid onto the outer surface of the packing tube around the free forward end of the packaged product. This folded film sheet is then joined with the packing tube film, either by heat-sealing, or by pressing it onto the packing tube film, wherein in the latter case the film has to be coated with pressure sensitive adhesive.
  • the method and apparatus of the present invention need less packing tube length extending beyond the tip of the packaged product since no twist needs to be formed. Therefore, less packing film is needed in order to form the packaged product. It was found that with the present invention the overall amount of packing film needed to form the package can be reduced by about 10%.
  • Another advantage of the present invention is that with the method and apparatus of the present invention also packing film materials such as polypropylene which could not be employed with the known twisting methods, can be used as packing film materials.
  • the film sheet formed in a front portion of the forward projecting end of the packing tube is formed such that at least one essentially planar first sheet portion is created which is inclined against the longitudinal axis of the package tube. Due to this inclination the pressing head, when advancing over the forward end of the packaged product, can easily fold the film sheet onto the packing tube around the forward end of the packaged product. It is particularly preferred to form two first film sheet portions which are symmetrical with respect to a plane including the longitudinal axis of the package tube and which are inclined in opposite directions against the longitudinal axis of the package tube. By this arrangement the pressing head when advancing over the free forward end of the packaged products folds the two first film sheet portions onto opposite hemispheres of the package tube.
  • one film sheet portion is inclined upwardly and the other downwardly, one film sheet portion will be folded onto the upper half and the other onto the lower half of the packing tube around the forward end of the packaged product.
  • a more uniform distribution of the film material folded and heat-sealed on the dome-shaped forward tip of the package is achieved.
  • not only a front portion of the packing film is pressed together but also the packing film around a forward end portion of the packaged product.
  • This can be achieved by adapting the clamping jaws to form, when closed, a recess of complementary shape to the forward end portion of the packaged product.
  • the clamping jaws can be adapted to receive the forward end portion of the packaged product within the recess and to press portions of the packing film surrounding the forward end portion of the packaged product together.
  • the film sheet surrounding the forward end portion of the packaged product can be in the form of a second essentially planar sheet portion.
  • the clamping jaws are pivotally mounted and arranged to be longitudinally movable, against a biasing force, in the direction towards the axis of the pivotal movement.
  • the clamping jaws when closing around the forward end portion of the packaged product, can adapt to the actual position of the forward end of the packaged product by moving backwardly against the biasing force if necessary, to thereby accommodate length variations of the packaged products.
  • Each clamping jaw can for example be attached to a rod which in turn is slidably received in a guiding cylinder of a pivot member. A spring force is acting on the rod to bias it into its extended position. This ability of the clamping jaw to move in a direction perpendicular to the pivot axis, i.e.
  • this arrangement of the clamping jaws to be movable in the direction towards the pivot axis has the further advantage that the clamping jaws, when closing with their recess around the forward end of the packaged product, in most cases (i.e. whenever the forward end of the packaged product extends beyond a predetermined position) perform a slight backward movement, thereby tightening the packing film around the packaged product and thus improving the quality of the package.
  • the clamping surfaces of the clamping jaws are pre-heated already before they reach the closed position to thereby shorten the time needed for heat-sealing the pressed film sheets, in order to allow to increase the speed or processing rate of the packaged products.
  • the pre-heating of the clamping surfaces is particularly advantageous if polypropylene is used as packing film because this material has a rather small temperature tolerance which means that it must not be overheated over the temperature needed for heat-sealing, or may be overheated only by a small fraction of about 10 % of the temperature needed for heat-sealing. For this reason the heat-sealing step cannot be accelerated by increasing the heating power of the closed clamping jaws.
  • the present invention can be used with all film materials useful in the field of packing technology.
  • films of cellulose hydrate which can be non-coated or coated with lacquer.
  • polymer coated cellulose hydrate films can be used, for example films with a coating of polyvinyl dichloride.
  • non-cellulose films of all kinds are suitable, for example polypropylene films.
  • composite films of all kinds can be used, for example combinations of cellulose hydrate films with co-extruded polypropylene (PPOS), with oriented polypropylene (PPO) or unoriented polypropylene (PPN).
  • composite films of cellulose hydrate films and polyethylene films can be use, or any combinations of cellulose hydrate films with polyamide, polyester, polyethylene and/or polypropylene layers.
  • plastic films with a metal coating for example with a aluminum layer can be used.
  • dry coated films and shrinking films can be used in connection with the invention.
  • the packing films to be utilized in connection with the present invention should have a thickness in the range of 20 to 120 ⁇ m. In principle all films can be processed which can be sealed either by heat-sealing or which have a pressure sensitive coating in the area to be closed.
  • Figure 1 shows the front part of the mounting and operating mechanism for the clamping jaws 10, 10' which are in their closed position.
  • the clamping jaws 10, 10' are mounted on pivot member 20, 20', respectively, which are pivotally mounted and which are operated by a rod mechanism for periodically opening and closing them.
  • the clamping jaws 10, 10' are shown in Figure 3 in their opened position.
  • Clamping jaw 10 (10') is mounted via a rod 12 (12') on a pivot member 20 (20') in which the rod 12 (12') is slidably received.
  • a spring force is acting on the rod 12 (12') to bias it to its forward, extended position as shown in Figure 1.
  • the clamping jaw 10 (10') is, at the first part of the movement, guided on a guiding surface 22 (22').
  • the clamping jaw 10 (10') comes free of the guiding surface 22 (22') so that the clamping jaw 10 (10'), when approaching the closed position, is free to move backwardly, with the rod 12 (12') moving further into the pivot member 20 (20') against a biasing force.
  • the clamping jaws 10, 10' By this resilient mounting of the clamping jaws 10, 10', they are movable towards their respective pivot axes, i.e. to the right hand side in the representation of Figure 1, in order to be able to adapt to the actual position of the forward end of the packaged product which is received in a recess 14 of the clamping jaws 10, 10'.
  • the design and operation of the clamping jaws 10, 10' can best be described in connection with Figures 3 and 4.
  • the clamping jaws are formed with a recess 14 being located in the center of the clamping jaws (see Figure 4) and are therefore shown in dashed or phantom lines in Figure 3.
  • the recess 14 is, when the clamping jaws 10, 10' are closed, of complementary shape to the dome-shaped forward end of the packaged product 2 so that the clamping jaws can be closed around a forward end portion of the packaged product 2.
  • second clamping surfaces 11, 11' Surrounding the recess 14 are second clamping surfaces 11, 11' which serve to press the packing film around a forward end portion of the packaged product received in the recess 14 in order to form an essentially planar second film sheet.
  • first clamping surfaces include opposite clamping surfaces 16, 16' and 18, 18' which are symmetrically located with respect to a plane perpendicular to the second clamping surfaces 11, 11', wherein opposite clamping surface 16, 16' and 18, 18' each form an essentially planar film sheet portion 6 and 8 (see Figure 3 and 5) which are inclined in opposite direction with respect to the longitudinal axis of the packaged product.
  • the open forward projecting end 3 of the package tube is formed by these first clamping surfaces 16, 16', 18, 18' into two essentially planar first film sheet portions 6, 8, being inclined in opposite directions with respect to the longitudinal axis of the packaged product, as schematically shown in the front view of Figure 5.
  • These two oppositely inclined film sheets or "flaps" 6, 8 are connected by an inclined intermediate film portion.
  • This inclined intermediate film portion is formed by the intermediate clamping surfaces which connect the first clamping surfaces 16 and 18, or 16' and 18', respectively.
  • first film sheet portions 6, 8 are formed in the region projecting beyond the forward tip of the packaged product.
  • a single essentially planar first film sheet can be formed which is preferably inclined against the longitudinal axis of the packaged product.
  • more than two first film sheet portions could be formed.
  • clamping jaws 10, 10' which do not include a recess 14 could be used.
  • the clamping jaws would only press a front portion of the forwardly projecting packing tube portion 3 to form a pressed film sheet in front of the forward end of the packaged product, without enclosing the forward end of the packaged product and without pressing the packing film surrounding the forward end of the packaged product.
  • the packing tube 1 around the packaged product 2 has, in the initial phase as shown in Figure 3 by dashed lines of the packing film 1, an open forward end portion 3 which projects beyond the forward end of the packaged product 2.
  • the packaged product 2 with the surrounding open packing tube 1 is held in the position shown in Figure 3 by a mechanism which is not shown.
  • the operating mechanism of the clamping jaws 10, 10' moves the clamping jaws to a closed position as shown in Figure 1, whereby the forward end portion of the packaged product 2 is received in the recess 14 and the forward projecting open packing tube portion 3 is pressed together to form two inclined first film sheet portions 6, 8 in front of the packaged product 2, and a second film sheet portion around the dome-shaped forward end of the packaged product.
  • the clamping surfaces 16, 16', 18, 18', 11, 11' are already pre-heated before the clamping jaws reach the closed position in order to introduce as much heat as possible in a short time period in order to achieve sealing of the first and second film sheet portions in the shortest possible time period without overheating the film material.
  • the packaged product 2 with its closed film sheet end portions 6, 8 is moved in front of a pressing head which has a recess of complementary shape to the front end portion of the packaged product 2.
  • This recess is moved over the front end portion of the packaged product 2 to thereby fold the first film sheet portions 6, 8 onto the packing tube 1 around the forward end of the packaged product, wherein the film sheet portion 6 will be folded onto the lower half and the film sheet portion 8 will be folded onto the upper half of the packaged product 2.
  • the second film sheet portions are pressed against the packing tube.
  • the walls surrounding the recess of the pressing head are pre-heated in order to melt the packing film material to join the film sheet portions with the packing film around the packaged product by heat-sealing.
  • the clamping jaws 10, 10' abut against guiding surfaces 22, 22' which guide the clamping jaws 10, 10' during a first part of their closing movement.
  • the guiding surfaces 22, 22' are shaped such that at a certain point of the closing movement the clamping jaws 10, 10' get free of the guiding surfaces when closing further and are held by the biasing force against their rods 12, 12' in their extended position.
  • the clamping jaws 10, 10' are thus free to move into the direction of their pivotal axes (i.e. to the right side in Figure 1) against the biasing force.
  • This elastically resilient mounting of the clamping jaws 10, 10' permits that, when their recess 14 closes around the dome-shaped forward end of the packaged product 2, they adapt to the actual position of the forward end of the packaged product and thus adapt to length variations of the packaged product. Furthermore, this elastically resilient mounting scheme of the clamping jaws 10, 10' has the effect that, since the clamping jaws will be arranged to slightly move backwards in case of the average product size, in most cases the clamping jaws when closing around the packaged product move slightly backwards thereby tightening the packing film around the packaged product and thus improving the quality of the packing.
