Abstract
A weigher for a packaging machine has buckets that deliver product batches. Each bucket includes a pair of spaced side walls between which a bottom extends, and over which the product passes. A bottom wall has at least one trough to control the trajectory of the product leaving the bucket to minimise angular velocity of the product about the vertical axis of a chute. The chute has a substantially vertical axis and receives the batches of product from the weighing buckets. The chute has a side wall converging downwardly from an upper opening to a lower opening, and an internal surface over which the product passes.
Claims4
A weigher bucket for a weigher of a packaging machine that delivers product to a chute having a vertical axis, said bucket including a pair of spaced side walls between which a bottom wall extends, and over which the product passes, said bottom wall having at least one trough to control the trajectory of the product leaving the bucket to minimise angular velocity of the product about the vertical axis of the chute.
A chute, having a substantially vertical axis, for a packaging apparatus, the chute being adapted to receive batches of product from weighing buckets, and wherein said chute has a side wall that surrounds said axis and that converges downwardly from an upper opening to a lower opening, and an internal surface over which the product passes, with said internal surface providing a plurality of radially and axially downwardly extending troughs which engage the product to inhibit angular movement thereof about said axis.
In combination:
- a weigher for a packaging machine, the weigher having buckets that deliver product batches, each bucket including a pair of spaced side walls between which a bottom extends, and over which the product passes, said bottom wall having at least one trough to control the trajectory of the product leaving the bucket to minimise angular velocity of the product about the vertical axis of the chute;
- and
- a chute having a substantially vertical axis and that receive the batches of product from the weighing buckets, and wherein said chute has a side wall converging downwardly from an upper opening to a lower opening, and an internal surface over which the product passes.
