Dispensing system for consecutively dispensing paper sheet material from a stub roll and a primary roll

摘要

A system for consecutively dispensing paper sheet material from a stub roll and a primary roll which utilizes a pivoted transfer door to locate a lead end portion of the primary roll in dispensing position responsive to disengagement between the transfer door and a pivoted lever supporting the stub roll.

主权项

1. Dispensing apparatus for consecutively dispensing paper sheet material from a stub roll of said paper sheet material and a primary roll of said paper sheet material having a lead end portion, said apparatus comprising:
a dispensing cabinet defining an interior; a primary roll holder within the dispensing cabinet interior for holding a primary roll of paper sheet material and allowing rotation thereof during dispensing of paper sheet material from said primary roll of paper sheet material; a stub roll holder within the dispensing cabinet interior spaced from said primary roll holder for holding a stub roll of paper sheet material and allowing rotation thereof during dispensing of paper sheet material from said stub roll of paper sheet material; a dispensing mechanism including a rotatable drum having an outer surface supporting paper sheet material from said stub roll during dispensing of paper sheet material from said stub roll; a lever having first and second lever ends and pivotally mounted within said cabinet interior, said stub roll holder comprising a spindle attached to, supported by, and extending outwardly from the first lever end; a stub roll support positioned below said spindle engaged by the outer periphery of a stub roll on said spindle and providing support for said stub roll, said stub roll holder and said first lever end, said stub roll holder biased in the direction of said stub roll support and movable toward said stub roll support during dispensing of paper sheet material from said stub roll; and a pivotally mounted transfer door having a proximal portion and a distal portion located within said cabinet interior adjacent to said rotatable drum and biased to move said distal portion toward said rotatable drum, the second lever end engageable with said transfer door to prevent movement of the distal portion toward the rotatable drum when the stub roll engages and is supported by said stub roll support, pivoting of said lever caused by exhaustion of the stub roll disengaging said second lever end from said transfer door and allowing pivoting of said transfer door and movement of the distal portion toward said rotatable drum to place the lead end portion of said primary roll into a position on said rotatable drum allowing dispensing of paper sheet material from said primary roll upon rotation of said rotatable drum.
