Abstract
The specification discloses a cardboard and blister pack packaging and sealing machine that includes an upper and lower heater and die combination that can be compressed together over a package for sealing using heat activated adhesives. The machine may use at least one piston and rod device or pump to provide the necessary energy or pressure. The machine may include a moveable tray containing at least one aperture to hold an unsealed package wherein the unsealed package can be moved proximate to the upper and lower heaters and dies and the upper and lower heaters and dies can press together. In this way, both the top and bottom dies may be heated and the operator is not required to remove the sealed packaging from the hot die.
Claims10
A cardboard and blister pack packaging and sealing machine comprising:
- a) an upper heater and controllably moveable downward by guide rods connected to a cylinder and piston combination;
- b) a lower heater and die controllably moveable upwards by a cylinder and piston combination;
- c) a moveable tray containing at least one aperture to contain an unsealed package wherein the unsealed package can be moved proximate to the upper and lower heaters and dies and the upper and lower heaters and dies can press together;
- d) a plurality of clips pivotably attached to the tray and moveable in response to movement of the lower die or heater and the clips may hold an unsealed package;
- e) each clip contains a beveled portion that causes the clip to pivot horizontally in response to contact with the upward movement of the lower die;
- and
- f) the moveable tray contains recesses for the pivoting clips.
A continuous peripheral edge package sealing machine comprising:
- a) a heatable top die containing extendible springs for contacting the package and die surface protrusions for pressing the package;
- b) a heatable bottom die containing extendible springs for contacting the package and die surface protrusions for pressing the package;
- c) a tray with pivoting clips for temporary holding the packages before and after compression of the die;
- d) a power source for moving at least one of the die into contact with the other die;
- e) each clip contains a beveled portion that causes the clip to pivot horizontally in response to contact with upward movement of the lower die;
- f) the tray containing recesses for the pivoted clips;
- and
- g) movement of the clips from the top and bottom die compression location.
A method for sealing a cardboard packaging comprising:
- a) positioning a moveable tray containing at least one aperture wherein and unsealed package can be positioned within the aperture and the package supported by pivoting clips and moved proximate to upper and lower heaters and dies;
- b) moving the upper heater and die downward wherein the movement is controlled by guide rods connected to a cylinder and piston combination;
- c) moving the lower heater and die upward by a cylinder and piston combination;
- d) pressing the upper and lower heaters and dies together with the unsealed package positioned between the upper and lower heaters and dies;
- and
- e) pivoting clips attached to the moveable tray in response to the upward moving lower heater and die contacting beveled portions of each clip causing the clips to pivot horizontally into recesses of the tray.
