Definitions

  • An actuating handle is pivotally mounted on the upper sealing clamp and has associated therewith web clamp and cutting means so arranged that, when the handle is depressed, upper and lower sealing clamps en gage and seal the periphery of a folded over web having an article placed therein and, as the handle is further depressed, the continuous web stock is cut from the sealed package and the free edge thereof engaged by the web clamping means.
  • the handle is subsequently retracted to return the upper sealing clamp to the open position, the web is drawn along thereby and placed in position for a subsequent sealing operation.
  • the invention relates to a device for packing objects in a heat sealable packing web, which device is provided with a frame supporting a pivotable upper sealing bracket, a lower sealing bracket co-operating with the upper sealing bracket, and a clamp device for the sealable web, which clamp device is attached to the upper sealing bracket, and so cooperating that with a reciprocal pivot movement of the upper sealing bracket whereby it is first retracted and subsequently extended, a portion of the web engaged by the clamp device is folded over another portion thereof, which portions can be sealed together by the sealing brackets in a closed area extending from the fold.
  • the invention aims to provide a device, with which the complete width of the sealable packing web can be made use of and in which the packing web need not be completely meltable, although such completely meltable webs may readily be used with the invention.
  • completely meltable webs webs which are not "ice completely meltable, e.g. consisting of a sheet of paper and a sealable layer, can be used.
  • a dividing device severing the web over its complete width is present and in that the clamping device, attached to the upper sealing bracket, is adapted to grip and retain the free end, that is formed by the severing action of the dividing device.
  • the packing web in the position of the device, in which an object to be packed can be laid on it, form a plain supporting surface. This enhances and speeds up the Work with the packing device.
  • the upper sealing bracket in the closed position in which the sealing brackets co-operate grips the packing web rim and takes the web along with the movement of the upper sealing bracket and can be pivoted to such extent that the packing web is almost positioned in a horizontal plane whereas with the return pivot movement of the upper sealing bracket no packing web transport occurs.
  • the sealing brackets are essentially U-shaped.
  • a constructively simple and reliable embodiment of the invention can be obtained, with a locking mechanism actionable by a handle, which locking mechanism is adapted to lock a clamp of the clamping device such that in the position of the handle in which closing pressure is exerted on the sealing brackets, the said clamp of the clamping device is locked.
  • FIGURE 1 shows a plane view of a first embodiment of the invention with the sealing brackets in the open position
  • FIGURE 2 shows the same device in elevation and in the closed position, interrupted lines showing an intermediate position
  • FIGURE 3 shows the same device again, in which especially the working of the sealing mechanism is indicated;
  • FIGURE 4 shows the same device in still a further work position
  • FIGURE 5 shows, partly in elevation and partly in cross-section a detail of a clamping device for the sealable web
  • FIGURE 6 shows partially a further embodiment of the invention
  • FIGURES 7 and 8 show the further embodiment in two different work positions in longitudinal cross-section.
  • FIGURE 9 shows the clamping device of the second embodiment in two different positions.
  • FIGURES 1-5 inclusive has an U-shaped lower sealing bracket 1 that is pivotally mounted on pins 2 which are attached to a support 3.
  • the support 3 itself can pivot at pins 4 that are also the pivot means for the eyes or trunnion ends 7 of an U-shaped sealing bracket 6.
  • a tension spring 8 is connected with the lower sealing bracket 1 by means of a pin 9 and with the support 3 by means of a pin 10, by reason of which the lower sealing bracket 1 normally is held against the rim 11 of the support 3.
  • a pin 13 is fixedly connected to the support 3 and at its end provided with a stop 16 which engages ring fixedly connected to the frame of the device, which engagement is caused by the working of a pressure spring 14 which is mounted between the rim 11 and the ring 15.
  • One of the sealing brackets 1 or 6 or both of them can be heated at its sealing surface 12 and 17 respectively.
  • the upper sealing bracket 6 bears a support 18 in which driving means in the form of an actuating handle 19 is mounted which can carry out a small pivotal move ment around a pin 20.
  • driving means in the form of an actuating handle 19
  • the nose 21 of the handle 19 engages the support 18.
  • a clamping device for gripping the packing web is actuated.
  • This clamping device is attached to the foreside of the upper sealing bracket 6 and is supported by a shaft 22, that can pivot in bearings 23 and 24 attached to the upper sealing bracket 6.
  • the clamping device is formed by a back clamp 26 and a fore clamp 27. With the back clamp 26 a cam member 25 is connected.
  • the clamps 26 and 27 are mutually subjected to a spring pressure in the closing direction by means of springs 28 and 29 mounted on pins affixed at their ends to the clamp 26. These springs are for the sake of clearness only shown in FIGURE 2 in the opened position drawn cross-section ally with interrupted lines instead of in full elevational view with uninterrupted lines.
  • the cam member 25 can co-operate with a stop member 30 attached to the handle 19 to prevent the clamp 26 from following the clamp 27 when the handle 19 is depressed.
  • a stop member 31 is connected, which by means of a finger 40 of the handle 19 can be pivoted clockwise for opening the clamp 27.
  • the packing web 34 is taken from a roll 32 and guided by means of one or more guide rolls 33. If the clamping device 26, 27 has gripped the web 34 and the upper sealing bracket is pivoted over 180', the sealing surfaces 12 and 17 of the sealing brackets 1 and 6 are positioned in a horizontal plane, on which the web 34 is positioned. The object to be packed can be put on the portion of the web above the lower sealing bracket 1, after which the upper sealing bracket 6 is pivoted back. At the end of this return pivot movement the sealing brackets 1 and 6 engage each other and by further pressure on the handle 19 the stop member 30 will lock the clamp 26 by means of the cam member 25. Following this the finger 40 engages member 31 by reason of which clamp 27 is pivoted clockwise in the opening direction.
  • the clamp 27 will then engage a strip 41 of elastic material by reason of which the packing web is clamped between 27 and 41.
  • the strip 41 With further lowering of the handle 19 the strip 41 will yield because it is pivotally mounted on the taps elongating the spring 38 which has been tensioned between the pins 36 and 37, so that a desired clamping action is maintained on the packing web 34 between clamp 27 and strip 41.
  • the pin 36 is attached to the support 3 and the pin 37 to a lever 39 which is connected with the support 42 of the strip 41. If the handle 19 is still lowered further the upper sealing bracket 6 lowers the lower sealing bracket 1, compressing spring 14.
  • the non elastic edge 42 retains clamp 27 in its open position when the finger 30 releases member 31, when the handle 19 moves back.
  • FIGURES 6-9 inclusive in many respects is identical to the described embodiment and corresponding members are indicated with the same references, so that it is considered that any further elucidation of them is superfluous.
  • the handle is not provided with a locking device for co-operating with the clamps, but that the stop member fixedly connected to clamp 27 is exposed to a spring action urging clamp 27 counter clockwise.
  • the cutting knife is T-shaped and consists of an upright portion 58 and two horizontally extending portions 59 and 60 respectively.
  • the clamp co-operating with clamp 27 is formed by two parts 50 and 51, which can pivot around the centerline of shaft 22 and again are urged by springs 28 and 29 towards clamp 27.
  • the clamp parts 50 and 51 have a protruding portion 52 and 53 respectively, which can co-operate with stop pins 54 and 55 respectively fixedly mounted in the frame of the device.
  • the clamping device consisting of the foreclamp 27 and both the back clamps 50 and 51 remain closed so that a space is created between the sealing brackets and the clamping device which space receives the knife 58, 59, 60.
  • the working of this embodiment of the invention is the following: When the sealing brackets are closed, the back clamps 51 and 52 are locked by the stop pins 54 and 55, so that they cannot pivot clockwise as viewed in FIGURE 8 around the shaft 22. By reason of this the clamping device 27, 50, 51 is opened and the clamps 50 and 51 move between the knife blades 59 and 60 and the sealing brackets.
  • the clamp 27 engages with its lower end the elastical strip 56 and retains the packing web, that is cut through by the knife 58, 59.
  • the sealing brackets pivot downwardly and the locking of clamps 51 and 52 is eliminated because the protruding portions 52 and 53 come below the pins 54, 55.
  • the L-shaped back clamps 50, 51 can pass the knife portions 59 and 60 and their lower side, so that they are ready to close immediately with clamp 27 under infiuence of the springs 28 and 29, when the handle again is moved upwardly, after which they take over and retain the edge of the web, kept between 56 and 27.
