Title:
A COMPACTOR AND A METHOD OF OPERATION OF A COMPACTOR
Document Type and Number:
WIPO Patent Application WO/2018/029079
Kind Code:
A3
Abstract:
A compactor (300) has a plunger housing (301) with a door (302) for insertion of waste. The plunger presses waste into a bag (B) on a pallet (P) within an enclosure (305) with panels (311, 312, 313) and a pair of panels in the form of doors (306) at the rear, which open to allow access by a truck to remove the pallet P with the bag in place on it. Side panels (311, 312), are joined along their lower edges to a floor panel 313, the side panels supporting the end panels (306) at vertical hinges (314). There is resilience due to the ability of the various panels to move, in which each side pan is cantilevered about the corner at which it is joined to the floor panel (313), and the end panels (306) can rotate about the relevant vertical axis of the hinges (314). As the plunger presses axially to compact waste within a bag (B) when the bag approaches being full, the resilient panels deflect so that they exert reaction forces on the return stroke of the plunger, thereby helping to achieve a uniform distribution of waste throughout the bag, and reducing power consumption. The controller may dynamically reduce plunger stroke length in response to sensing of panel deflection above a threshold.
