Title:
DYNAMIC MODULAR CHECKWEIGHER
Document Type and Number:
WIPO Patent Application WO/2022/262771
Kind Code:
A1
Abstract:
The present invention provides a dynamic modular checkweigher, comprising: a weighing and conveying matrix unit having a weighing and conveying surface composed of a plurality of weighing and conveying sub-units; a weighed object identification unit for identifying a weighed object and a coverage thereof by means of images or weights of the weighing and conveying sub-units; a weighed object conveying movement control unit for controlling arrangements of a plurality of weighed objects on the weighing and conveying matrix unit; a weighed object movement tracking unit for identifying a movement trajectory of a weighed object and creating a time sequence-based data set of movement state, movement position, and weighing signal from data of the weighing and conveying sub-units covered by the weighed object; and a weighed object weighing module unit for acquiring a weighed object data set created on the basis of the weighed object movement tracking unit. The various parts mentioned above are connected to a host system to form a star topology. According to the present invention, package separation functions such as unpacking, arranging, and pulling of a package separation system can be achieved, and mutual interferences in weighing objects by the checkweighercan be reduced.
