ABSTRACT:
An empty bobbin supply device for use in a doffing machine which travels in front of spinning units and is adapted for doffing a cheese and donning an empty bobbin in place thereof. This empty bobbin supply device has a reserve box, a reserve conveyor and a horizontal transfer conveyor, which are all positioned substantially in a vertical direction. An empty bobbin comes downwardly by gravity from the reserve box and is received between transfer plates of the reserve conveyor. The bobbin is then transferred downwardly by the circulating reserve conveyor, and in the absence of a bobbin on the horizontal transfer conveyor, the bobbin is delivered therefrom, while when a bobbin is present on the transfer conveyor, the bobbin remains on the reserve conveyor. The terminal of the horizontal transfer conveyor serves as a stand-by position for an empty bobbin in the doffing portion.
