Dynamic scale for flat goods transported their sides, and control method therefor

A dynamic scale having an input side at which an individualized item to be weighed, among plurality of items to be weighed, enters said dynamic scale, and an output side at which each item exits said dynamic scale, said dynamic scale comprising:

• a thickness measurement assembly at said input side of said dynamic scale;
• a weighing plate with transport belts of a transport device that transport the item to be weighed across said weighing plate in a transport direction from an input side of said weighing plate to an output side of said weighing plate;
• a width measurement assembly situated at said output side of said dynamic scale;
• a takeoff device situated at said output side of said output side of said dynamic scale, comprising an ejection roller;
• a first sensor situated at said input side of said weighing plate, a second sensor situated at an output side of said weighing plate, and a third sensor situated in said takeoff device;
• a control processor in communication with said thickness measurement assembly, said transport device, said width measurement assembly, said takeoff device, and said first, second and third sensors;
• said control processor being configured to start a length measurement of a first of the items to be weighed by operating said transport device to drive said transport belts with a first velocity, when said first sensor detects a leading edge of said first of said items;
• said control processor being configured to start dynamic weighing of said first of said items using said weighing plate until said second sensor detects said leading edge of said first of said items;
• said control processor being configured to check whether a valid weight measurement from said dynamic weighing was provided to the control processor by the weighing plate and, if so, to determine a weight of said first of said items from said valid weight measurement, and to operate said transport device to further transport said first of said items with said first transport velocity in said transport direction to said takeoff device;
• said control processor being configured to determine the weight of the first of said items if said dynamic weighing has not ended and to operate said transport device to further transport said first item with a second transport velocity in said transport direction to said takeoff device, with said second transport velocity being lower than said first transport velocity;
• said control processor being configured to operate said width measurement assembly to make a width measurement of said first item;
• said control processor being configured to end said dynamic weighing when said third sensor detects the leading edge of said first of said items and said check determines that no valid weight measurement result for said first of said items is present;
• said control processor being configured to supply a next of said items, among said plurality of items to be weighed, at said input side of said dynamic scale if said check determines that said valid weight measurement result for said first of said items is present;
• said control processor being configured to operate said ejection roller with a third transport velocity in said transport direction in order to eject said first item from said takeoff device, said third transport velocity being greater than said first transport velocity;
• and
• said control processor being configured to repeat said length measurement, said dynamic weighing, said check, said width measurement, and the transport of each subsequent item in said plurality of items to be weighed as long as no stop command is provided to said control processor.
