Abstract
The invention pertains to a method for weighing at least one object (31) that can be or is moved relative to a number of weighing cells (3, 5, 7, 9) and to a device for effecting said method, wherein the weighing cells (3, 5, 7, 9) essentially are adjacently arranged transverse to the movement direction (T) and the weighing signals being generated while weighing at least one object (31) are coupled with one another.
Claims8
A method for weighing at least one object that is movable along a transport path in a direction of movement, the method including:
- (a) arranging a number of essentially adjacent, respectively active independent weighing cells along a weighing cell line which crosses the transport path in a direction transverse to the direction of movement, each respective weighing cell being mechanically coupled to a respective transport device which is adapted to transport at least a portion of the at least one object along the transport path, and each respective weighing cell generating a respective weighing signal in response to weighing the at least one object while such object is at least partially supported by the transport device coupled to that respective weighing cell;
- (b) selecting respective weighing signals for coupling as a function of the size of the object, or the position of the object, or both the size of the object and the position of the object;
- and
- (c) coupling two or more of the respective weighing signals.
A weighing device for weighing at least one object that is movable along a transport path in a direction of movement, the weighing device including:
- (a) a number of essentially adjacent, respectively active independent weighing cells arranged in a weighing cell line, the weighing cell line crossing the transport path transverse to the direction of movement, each respective weighing cell generating a respective weighing signal in response to weighing the at least one object;
- (b) a respective transport device for each respective weighing cell, the respective transport device for a respective weighing cell being adapted to transport at least a portion of the at least one object along the transport path and being mechanically coupled to the respective weighing cell such that weighing the at least one object by the respective weighing cell is accomplished while the at least one object is at least partially supported by the transport device for that respective weighing cell;
- (c) wherein two or more of the respective weighing signals are coupled together;
- and
- (d) wherein selecting respective weighing signals for coupling is performed as a function of the size of the object, or the position of the object, or both the size of the object and the position of the object.
