Dunnage system with coiler, automated taping and ejecting apparatus and method
View Patent ↗A dunnage conversion system includes a machine for converting a stock material ( 14 ) into a strip of relatively lower-density dunnage, a coiling mechanism ( 20 ) for winding the strip into a coil, a taping mechanism ( 22 ) for automatically securing a trailing end of the strip to the coil, and a coil ejecting mechanism ( 24 ) for automatically removing the coil from the coiling mechanism. The taping mechanism includes a guide surface ( 70 ) between an outlet of the machine and the coiling mechanism to guide the strip to the coiling mechanism and to guide tape for engagement with a trailing end of the strip and to secure the trailing end of the strip to the coil. The coil ejecting mechanism includes a lever arm ( 126 ) that pivots to push the completed coil off the coiling mechanism.
1. An automatic taping mechanism for use with a dunnage conversion machine and a coiling mechanism for coiling a strip of dunnage, comprising:
a supply of tape;
a guide surface extending between an outlet of the dunnage conversion machine and the coiling mechanism to guide a strip of dunnage to the coiling mechanism and to guide a strip of tape for engagement with a trailing end of the strip of dunnage to secure the trailing end of the strip of dunnage to the coil, the guide surface having a groove extending along the guide surface for receipt of the strip of tape and an inlet opening in the groove for receipt of the strip of tape from the supply of tape, the supply of tape being located on an opposing side of the guide surface opposite the groove;
a pivoting body downstream of the inlet opening that is configured to move a portion thereof toward the groove to press the trailing end of the strip of dunnage into engagement with the strip of tape within the groove; and
a severing mechanism spaced downstream of the inlet opening for separating a length of tape from the supply.
2. An automatic taping mechanism as set forth in claim 1 , where the severing mechanism includes a punch mounted to the pivoting body, the pivoting body configured to move the punch toward the groove to pierce the tape and encourage the separation thereof.
3. An automatic taping mechanism as set forth in claim 1 , comprising a guide surface mountable adjacent the outlet of the conversion machine to guide a strip of dunnage from the outlet of the conversion machine to the coiling mechanism.
4. An automatic taping mechanism as set forth in claim 1 , in combination with a coiling mechanism that rotates about an axis to roll the strip of dunnage into a coil, where the axis of the coiling mechanism is parallel to the guide surface.
5. An automatic taping mechanism as set forth in claim 1 , in combination with a dunnage conversion machine that converts a stock material into the strip of dunnage to be coiled, the dunnage conversion machine dispensing the strip of dunnage from an outlet, and the guide surface is mounted between the outlet of the conversion machine and the coiling mechanism.
6. An automatic taping mechanism as set forth in claim 5 , further comprising a supply of stock material for conversion into a relatively less dense dunnage product.
7. An automatic taping mechanism as set forth in claim 6 , where the stock material includes one or more of a sheet of paper and a sheet of kraft paper.
8. An automatic taping mechanism for use with a dunnage conversion machine and a coiling mechanism for coiling a strip of dunnage, comprising:
a supply of tape; and
a guide surface extending between an outlet of the dunnage conversion machine and the coiling mechanism to guide a strip of dunnage to the coiling mechanism and to guide a strip of tape for engagement with a trailing end of the strip of dunnage to secure the trailing end of the strip of dunnage to the coil; and
a pivoting body downstream of the inlet opening that is pivotable about a pivot axis, the pivoting body having a first portion on a first side of the pivot axis that is pivotable toward the guide surface to press the trailing end of the strip of dunnage into engagement with the strip of tape, and a second portion on a second side of the pivot axis opposite the first side, the second portion including a punch that is movable toward the guide surface to pierce the tape and encourage the separation thereof for separating a length of tape from the supply.
