  • Patent number: 7954302
    Abstract: An apparatus for sealing a cover film to a blister film having blisters holding respective small objects has a feed roll rotatable about an axis and formed with an array of radially outwardly open recesses arrayed like the blisters of the blister film. The blister film passes over the feed roll with the blisters in the recesses. A sealing roll is rotatable about an axis generally parallel to the feed-roll axis and presses the cover foil down against the blister foil on the feed roll. The feed roll is rotated to pull the films in a travel direction between the rolls so that the cover film is sealed to the blister film between the blisters thereof. A sensor detects movement of the sealing roll transversely of the feed-roll axis. A controller generates an output when the detected movement exceeds a threshold.

  • Patent number: 6895732
    Abstract: A packaging apparatus includes a pair of rolls forming a nip through which two web portions are passed with an item to be packaged between the web portions. The rolls include resiliently compliant roll portions that deform to accommodate the thickness of the item, and the roll portions press the web portions to seal them together in peripheral regions surrounding the item and to center the item between the webs in the thickness direction. The apparatus also includes side seal devices that traverse inwardly toward the item to seal the webs together close to the item's opposite side edges to prevent the item from laterally shifting. The web portions may have cohesive disposed on their facing surfaces such that the web portions adhere to each other with pressure but tend not to adhere to the packaged item or other surfaces.

  • Patent number: 6729113
    Abstract: A lateral sealing mechanism for use in a bag-making and packaging machine includes movable rotary shafts. The movable rotary shafts are driven by a lateral drive mechanism so that the distance between the shafts is controllable. Support mechanisms are mounted on and rotatable about the shafts. The support mechanisms support sealing elements for forming lateral heat seals on a tubular packaging material from which the bags are formed. The support mechanisms are such that the sealing elements are tiltable with respect to the tubular packaging material, and so that two sealing elements can be maintained in directly opposed engagement to one another across the packaging material as the seal is formed. The machine includes a squeezing mechanism that operates to force the packaged material downward within the tubular material and out of a sealing region before the seal is formed.

  • Patent number: 6408596
    Abstract: In order to reduce the technical input for a device for packaging, for example a horizontal bagging machine, it is suggested to provide two sealing jaws which act against one another and weld a foil web, only one sealing jaw for a rotating operation. The second sealing jaw is co-moved along a path with the first sealing jaw in transport direction of the foil path and is moved back in opposite direction of the foil web. The second sealing jaw is fastened on a carriage which is moved along a horizontal rail, and a carrier connection transfers the component of the rotation motion of the first sealing jaw onto the second sealing jaw, which component extends in the foil transport direction.

    Abstract: In a machine for packaging stacks of multiply articles of paper into wrapping sheets, a first line conveys stacks of multiply articles of paper to a a wrapping station while a second feeds wrapping sheets to the wrapping station. Each sheet is kept vertically in a waiting position in the wrapping station until one stack is moved towards the sheet, so that the sheet gradually folds around the stack with overlapping parallel edges to be heat-welded. In the said second line there are first endless belts and second endless belts for a wrapping sheet received from conveying means situated upstream. The sheet is pulled up to the wrapping station and is clamped in the wait position by suction.

    Abstract: A method and apparatus for controlling operation of a bag-forming and -filling packing apparatus for supplying unsealed packaged articles (45) to a rotary vacuum packaging machine at regular intervals, in which the rotary vacuum packing machine is subjected to significant variations in loads. A main controller (115) for receiving pulse signals calculates modulation of the pitch of pulses from a main motor (86) of the rotary vacuum packaging machine, and control elements (94, 95, 96, 97) each attached to a corresponding one of all servo motors (20, 30, 40, 76) of the bag-forming and -filling packaging machine individually and simultaneously control the rotation value of each servo motor. This configuration can avoid step-wise control of each servo motor and reduce impacts on a rotary section and a failure rate while maintaining a slow control operation.
