Definitions

  • the present invention relates to a method for closing a packing consisting of two parts, by placing the parts one on the other, and subsequently folding a downward hanging edge of the one part round a protruding flange of the other part, by applying to the part of the edge lying under the flange first compressive forces directed towards each other, the lines of action of which are directed substantially parallel to the main plane of the flange.
  • a method for closing a packing consisting of two parts, by placing the parts one on the other, and subsequently folding a downward hanging edge of the one part round a protruding flange of the other part, by applying to the part of the edge lying under the flange first compressive forces directed towards each other, the lines of action of which are directed substantially parallel to the main plane of the flange.
  • the invention has for its object to provide a method as described above, wherewith a packing can be closed more rapidly and simply than previously. According to the invention this is achieved in that at least two pairs of compressive forces are applied whereof the lines of action are in different directions.
  • a very good closing of the packing is achieved by applying to the folded edge part and the flange second compressive forces directed toward each other, the lines of action of which are directed substantially transversely of the main plane of the flange.
  • the invention further relates to an apparatus for closing a packing consisting of two parts, including means for holding the packing in a closing position and means for folding a downward hanging edge of the one packing part round a protruding flange of the other part of the packing, which folding means take the form of a ring, the peripheral form of which corresponds with that of the packing.
  • the invention therefore has the further object of providing a closing apparatus of the above described type wherein these drawbacks do not occur.
  • the segments can be movable from the first closing position substantially transversely of the compressive surface embodied as profiled pressure plate to a second closing position in which the flange and the folded edge are pressed together between the ring segments and the pressure plate.
  • each ring segment has a nose portion which co-acts in the second closing position with a rib arranged running round the pressure plate for pressing together the flange and the edge to form a bead.
  • each ring segment When each ring segment is slidably mounted on the pressure plate, a spacer member is arranged between each segment and the pressure plate and the pressure plate has a number of spacer member-receiving spaces which are arranged such that in the first closing position each spacer member is in register with a receiving space and is received therein during a movement to the second closing position, the compressive forces can be applied to the packing while maintaining the folding forces.
  • the apparatus can comprise a base carrying the holding means and a closing part arranged on the base and carrying the pressure plate, wherein the closing part can pivot between an opened position for introducing or removing the packing and a closed position.
  • the closing apparatus preferably has a recess arranged in the base for receiving the packing and stops protruding out of the pressure plate, wherein the depth of the recess and the height of the stops are geared to one another such that in the closed position of the closing part the distance between a bottom surface of the recess and the pressure plate corresponds with the height of the packing.
  • the apparatus preferably has at least one filler piece arranged in the recess.
  • a closing apparatus that is simple to operate has control means connected to the segments, which control means can include a lever pivotally arranged on the pressure plate, a bridge piece pivotally connected to the lever and movable substantially transversely of the main plane of the pressure plate and pivot arms connecting the bridge piece to the ring segments.
  • An apparatus 1 for closing a packing 4 consisting of two parts 2, 3 (fig. 1) comprises a base 5 having arranged thereon means 6 closely enclosing the packing for holding the packing 4 in a closing position.
  • a closing part 7 of the apparatus 1 is hingeably arranged on the base 5 and comprises a pressure surface 8 in the form of a profiled pressure plate, ring segments 9 mounted slidably therein, a lever 10 connected to the ring segments 9 over a control mechanism (not shown here), a protective cover 11 for the control mechanism, and stop bosses 13 co-acting with stop recesses 12 of the base 5.
  • the upper part 3 In order to close the packing 4 the upper part 3 is placed in the manner indicated by the arrows onto the bottom part 2, whereby a downward hanging edge 16 of the upper part 3 falls round a protruding flange 15 of the bottom part 2.
  • the packing 4 is then placed in a recess 25 in the base 5 between the holding means 6.
  • the closing part 7 is then pivoted downward using the lever 10 counter to the action of a hold-open spring 17 (fig. 6A) until the bosses 13 rest in the stop recesses 12.
  • the apparatus 1 is dimensioned such that in this position the upper part of the packing 4 just makes contact with the pressure plate 8 (fig. 6B). (For packagings 4 with a different height filler pieces (not shown here) can be placed in the recess 25 in the base 5).
  • the inner periphery of the ring 14 formed by the segments 9 is larger in this position than the outer periphery of the flange 15.
  • the lever 10 is then moved further downward whereby the ring segments 9 are moved towards each other from their release position into a first closing position in which the inner periphery of the ring 14 is smaller than the outer periphery of the flange 15.
  • the downward hanging edge 16 of the upper packing part 3 is hereby folded round the protruding flange 15 of the bottom packing part 2 (fig. 6C).
  • the movements of the ring segments 9 are controlled by a control mechanism 18 (fig. 2) connecting the lever 10 and the segments 9 and consisting of a bridge piece 19 and pivot arms 20 connecting the bridge piece 19 to the ring segments 9.
  • the bridge piece 19 is pressed onto the pressure plate 8 using bias springs 21 supporting against the cover 11, so that the ring segments 9 can be held by the pivot arms 20 in their release position located furthest to the outside.
  • the spacer member 23 When the ring segment 9 has reached the first closing position, the spacer member 23 is situated in register with a receiving space 24 recessed into the pressure plate 8, so that the segment 9 is moved toward the pressure plate 8 to the second closing position under influence of the upward directed force exerted by the pivot arm 20 (fig. 5, 6D).
  • the spacer member 23 takes a cylindrical form (fig. 7), and is received in a semi-cylindrical recess in the ring segment 9.
  • the ring 14 in the embodiment shown is divided into segments 9 such that a segment 9 engages onto each corner of the packing 4, a uniform force can be exerted on the edge 16 in all directions using a minimum number of separate segments 9. It is however conceivable to divide a folding ring 14 of the form shown into a larger or smaller number of segments 9. This results however in a greater mechanical complexity or a less good distribution of force.
  • a closing apparatus 1 for use with a rectangular packing 4.
  • the invention can however also be applied with packagings of a shape other than that shown here, wherein the shape of the closing ring 14, of the recess 25 and of the holding means 6, the number of segments 9 and the control mechanism 18 can then be adapted correspondingly.
