Abstract
A molded fiber part production line includes a forming station, a part transfer system, a press station, and a removal system. The forming station includes a slurry tank, a forming mold, and a mold actuation system. The part transfer system includes a part transfer feature and a conveyance mechanism. The press station includes a core mold, a cavity mold compatible with the core mold, and a press actuation system. The removal system includes a removal feature defining a plurality of part vacuum channels and a plurality of trim vacuum channels. The removal system also includes a conveyance mechanism for moving the removal feature from a position in engagement with at least one of the core mold and the cavity mold to another position.
Claims16
A molded fiber part production line comprising:
- (a) a forming station comprising:
- a slurry tank configured to receive a fiber slurry comprising a plurality of fibers and a liquid;
- a forming mold comprising a mold plate defining a plurality of vacuum channels;
- and
- a mold actuation system for adjusting a position of the mold plate relative to the slurry tank;
- (b) a part transfer system comprising:
- a part transfer feature defining a plurality of part vacuum channels;
- and
- a conveyance mechanism for moving the part transfer feature from a first position in engagement with the forming mold to a second position;
- (c) a press station comprising:
- a core mold;
- a cavity mold compatible with the core mold, wherein at least one of the core mold and the cavity mold comprises a trimmer, and wherein the trimmer and the at least one of the core mold and the cavity mold form a unitary part;
- and
- a press actuation system for adjusting a position of the core mold relative to the cavity mold, wherein at least one of the core mold and the cavity mold comprises a plurality of vacuum channels, a plurality of heating elements, and a plurality of temperature sensors, wherein the core mold and the cavity mold are divided into multiple segments and a temperature of each segment is independently monitored and controlled, and wherein in the second position, the part transfer feature is in engagement with at least one of the core mold and the cavity mold;
- and
- (d) a removal system comprising:
- a removal feature defining a plurality of part vacuum channels and a plurality of trim vacuum channels;
- and
- a conveyance mechanism for moving the removal feature from a third position in engagement with at least one of the core mold and the cavity mold to a fourth position.
