MULTI-CONVEYOR SPEED ADJUSTER

摘要

A device and a method for transferring articles between an infeed conveyor at a first speed and an outfeed conveyor at a second speed different than the first speed include use of at least a first variable speed conveyor downstream of the infeed conveyor, and a second variable speed conveyor downstream of the first variable speed conveyor and upstream of the outfeed conveyor. The speeds of the variable speed conveyors are cycled between the first speed and the second speed without any article being conveyed by conveyors at different speeds. At least one additional variable speed conveyor may be included.

1. A device for transferring articles between an infeed conveyor at a first speed and an outfeed conveyor at a second speed different than the first speed, the device comprising:
a first variable speed conveyor downstream of the infeed conveyor; a second variable speed conveyor downstream of the first variable speed conveyor and upstream of the outfeed conveyor; a first motor for driving the first variable speed conveyor selectively between the first speed and the second speed; a second motor for driving the second variable speed conveyor selectively between the first speed and the second speed; a controller for controlling the speeds of the first and second motors as articles move sequentially along the infeed conveyor, the first variable speed conveyor, the second variable speed conveyor and the outfeed conveyor so as to sequentially move a given article from the infeed conveyor to the first variable speed conveyor, the second variable speed conveyer and the outfeed conveyor while cycling the speed of the first and second variable speed conveyors between the first speed and the second speed without the given article being conveyed by conveyors at different speeds.
