Definitions

  • a bag tying machine having an adhesive tape supply reel, a tie forming mechanism for applying adhesive tape from the supply reel to the gathered together end of a filled bag to form an adhesive tape tie, an adhesive tape path leading from the supply reel to the tie forming mechanism and a printer including a print head which engages and prints onto the non-adhesive side of the adhesive tape
  • a plattern is mounted beneath the belt and is located directly opposite the printer to give firm support to the belt when the print head engages and prints on the non-adhesive side of the adhesive tape. This enables the print head to print evenly on the adhesive tape.
  • the slidable carriage is held in position by a manually releasable clamp. On releasing the clamp the slidable carriage is moveable manually to adjust the length of the adhesive tape path between the printer and the adhesive tape tie forming mechanism. The slidable carriage is then re-clamped into the new position.
  • the bag tying machine is basically similar to that shown and described in EP-A-0128687. It includes a pair of endless belts 1 and 2 which come together to form a nip and act as a guide to receive the open end of the filled bag.
  • the pair of arms 3 an 4 which are pivoted around pivots 5 and 6 respectively, also help to define a guide between which the gathered together open neck of the bag passes.
  • the arms 3 and 4 are spring loaded and biased towards one another by springs 7. As the gathered together open end of the bag is drawn between the nip of the belts 1 and 2, opposite sides of the bags are drawn together.
  • the leading end of the bag is engaged by a first pair of jaws 12 and 13 formed on the arms 3 and 4 and further movement of the follow up member 11 compresses the end of the bag against the jaws 12 and 13 to gather it together.
  • a pneumatic ram (not shown) is actuated to move a subsidiary clamp 14 downwards so that it clamps the free end of the filled bag in position.
  • the adhesive tape supply mechanism including adhesive tape supply reel 17 printer unit 18, paper tape supply reel 19, feed rolls 20 and 21, cutters 22 and 23 and a gripper unit 24 are conventional in construction and are also described in our earlier specifications GB-A-1,381,871 and GB-A-1,517,031.
  • the pneumatic ram is deactuated to release the subsidiary clamp 14 and thereby release the free end of the filled bag and also the gripper unit 24 is operated to move the grippers 24 through an aperture formed in the arms 3 and 4 to grip the free end of adhesive tape from the reel 17 and pull this free end down so that it is held across the path of the gathered together neck of the bag.
  • Paper tape from the reel 19 is adhered in spaced lengths to the adhesive tape as fully described in our earlier specifications.
  • the follow up-member 11 returns to its initial position and the pneumatic ram 10 is deactuated so that it returns out of the path of the following gathered together neck of the bag and then the cycle is repeated.
  • Adhesive tape 38 is pulled from the adhesive tape reel 17 and engages the belt 27 of the print shift unit 26 before it passes to the feed rollers 21 and 25 and then to the tie forming mechanism.
  • the print head from the print unit 18 engages the non-adhesive side of the adhesive tape 38 at regular intervals at a position opposite that of the plattern 32.
  • the plattern 32 gives a firm support to the belt 27 thereby enabling the print head from the print unit 18 to print evenly on the adhesive tape 38 without distorting it.
  • the path length of the adhesive tape 38 between the print head and the tie forming mechanism can be altered thereby adjusting the position of the print on the completed adhesive tape tie. This adjustment is achieved by disengaging the clamp 33 and moving the slidable carriage 31 manually up or down as seen in Figure 2. The clamp 33 is then used to lock the slidable carriage 31 in to its new position.
