Retractable transfer device metering apparatus and methods
First Claim
1. Method for metering product comprising:
- conveying a continuous stream of product arranged in multiple rows in a conveying direction at a first conveyance speed for transfer unto a first product conveyance mechanism moving in the conveyance direction at a second conveyance speed greater than the first conveyance speed, with conveying the continuous stream of product comprising conveying the continuous stream of product from a second product conveyance mechanism onto a transfer device and from the transfer device to the first product conveyance mechanism; and
abutting lead product on the first product conveyance mechanism with a metering bar moving in the conveying direction at the first conveyance speed until a group of product including a number of rows from the continuous stream of product has been transferred onto the first product conveyance mechanism at which time the group of product on the first product conveyance mechanism is allowed to accelerate to match the second conveyance speed.

Abstract
Product is conveyed as a continuous stream by a meter conveyor (12) unto a transfer plate (32) and a transfer device (42). The transfer device (42) is movable between a retracted position and an extended position extending over a sweep conveyor (22). In a preferred form, the transfer device (42) is in the form of a thin piece of flexible material and is moved in the conveying direction from the retracted position to the extended position by engaging with the sweep conveyor (22) and is moved to the retracted position by being wrapped around a rotated roller (46). Product is transferred from the transfer device (42) to the sweep conveyor (22) as the transfer device (42) moves from the extended position to the retracted position and is engaged by a metering bar (52ba) which controls the product acceleration on the sweep conveyor (22) to match the meter conveyor (12) until the product group leaves the transfer device (42). With nested product, the leading edge of the transfer device (42) is scalloped to represent the product bottom leading edge.
