Wrapping sheet dispenser for roll wrapping machine

Abstract

Abstract A ROLLER WRAPPING MACHINE IS PROVIDED WITH STRUCTURE FOR SUPPORTING A ROLL OF WRAPPER PAPER ABOVE A WRAPPING STATION. A VACUMN BOX HAVING A FLAT DOWNWARDLY INCLINED WRAPPING PAPER GUIDING SURFACE IS ARRANGED BETWEEN THE WRAPPING STATION AND THE WRAPPER ROLL. A LOWER END OF THE BOX IS ARRANGED ADJACENT THE LOWER PORTION OF A ROLL TO BE WRAPPED AT THE WRAPPING STATION AND AN UPPER END OF THE BOX IS BOTH ABOVE AND REARWARD OF THE LOWER END. A ROLLER IS MOUNTED FOR ROTATION ABOUT ITS CENTRAL AXIS IN PARALLEL SPACED ALIGNMENT WITH THE UPPER END OF THE BOX AND ANOTHER ROLLER IS MOUNTED FOR ROTATION ABOUT ITS CENTRAL AXIS IN PARALLEL SPACED ALIGNMENT WITH THE LOWER END OF THE BOX. THE WRAPPING PAPER GUIDING SURFACE IS PROVIDED WITH A PLURALITY OF ELONGATED SLOTS EXTENDING ALONG THE SURFACE PERPENDICULAR TO THE ROLLERS. A PLURALITY OF ENDLESS AIR PERVIOUS BELTS ENCIRCLE THE ROLLERS WITH EACH BELT LAPPING ONE OF THE SLOTS. AN AIR EVACUATING PUMP IS CONNECTED TO THE BOX FOR EVACUATING AIR FROM THE BOX AND DRAWING AIR INTO THE BOX THROUGH THE BELTS AND SLOTS HOLD A PORTION OF THE WRAPPING PAPER FLAT THEREON. A DRIVE MOTOR IS CONNECTED TO ONE OF THE ROLLERS TO MOVE THE BELTS, AND WRAPPING PAPER HELD FLAT THEREON, DOWNWARDLY ALONG THE GUIDING SURFACE TO DISPENSE THE WRAPPING PAPER FROM THE LOWER END OF THE BOX ALONG A PATH CONVERGING TOWARD THE WRAPPING STATION. THE UPPER END OF THE BOX IS SUPPORTED FOR PIVOTAL MOVEMENT ABOUT A HORIZONTAL AXIS PARALLEL TO THE GUIDING SURFACE. A POWER OPERATED ACTUATING LINKAGE IS OPERATIVE TO PIVOT THE BOX ABOUT THE HORIZONTAL AXIS AND SWING THE LOWER END OF THE BOX TOWARD THE WRAPPING STATION TO PLACE THE LEADING EDGE OF WRAPPING PAPER HELD ON THE GUIDING SURFACE, IN FLAT CONTACT WITH A LOWER PORTION OF A ROLL TO BE WRAPPED. THE BOX IS SUPPORTED BY TRACKS FOR UPWARD MOVEMENT TO AN ELEVATED POSITION IN WHICH THE LOWER END OF THE BOX CLEARS A SPACE THROUGH WHICH A WRAPPED ROLL MAY BE DISCHARGED. D R A W I N G
