<p>A weighing and batching system (10) for weighing and collecting a batch of articles within a target weight interval comprises a frame defining a top and a bottom opposite the top, and a feeder system (18) having an inlet for receiving the articles and a plurality of outlets for discharging the articles. The system further includes a first plurality of weighing pans (22) mounted in the frame. Each weighing pan defines a first open end (42) and is oriented upwardly and positioned below the outlets of the feeder system (18) for receiving a portion of the articles discharged from a respective outlet. Each weighing pan (22) includes a first actuator for operating the respective weighing pan between a weighing state and a transfer state. Each weighing pan (22) includes a first weighing transducer for generating a first signal representing the weight of the portion received and defines a first receiving volume. The system also includes a second plurality of weighing pans mounted in the frame. Each weighing pan (30) defines a second open end and is oriented upwardly and positioned below the outlets of the feeder system (18) for receiving a portion of the articles discharged from a respective outlet. Each weighing pan (30) includes a second actuator for reversibly operating the respective weighing pan between a weighing state and a transfer state. Each weighing pan includes a second weighing transducer for generating a second signal representing the weight of the portion received and defines a second receiving volume, the second receiving volume being 2 to 50 times the first receiving volume, such as 5 to 45, such as 10 to 40, such as 15 to 30, such as 15 to 25, such as 17 to 21, such as 2 to 5, such as 5 to 10, such as10 to 15, such as 15 to 20, such as 20 to 25, such as 25 to 30, such as 30 to 35, such as 35 to 40.</p> |
