Abstract
A weighing apparatus for a filling line for filling containers of pharmaceutical, medical, food products and the like includes a weighing unit and a suction unit designed to generate a suction air flow directed and adjusted in such a way as to affect in a controllable manner the value of a weight detected by the weighing unit.
Claims17
A weighing apparatus for a filling line for filling containers of pharmaceutical, medical, food products, comprising:
- at least one weighing unit including at least one weighing device including at least one container support and at least one sensor unit which detects a value of a weight force acting on the container support;
- and
- at least one suction unit which generates a suction air flow that is directed and adjusted in such a way as to controllably affect the value of said weight force detected by said at least one sensor unit;
- a container advancing device which moves the containers along an advancing direction and a container transferring device which transfers the containers between said container advancing device and said at least one weighing unit, respectively.
A weighing apparatus for a filling line for filling containers of pharmaceutical, medical, food products, comprising:
- at least one weighing unit including at least one weighing device including at least one container support and at least one sensor unit which detects a value of a weight force acting on the container support;
- at least one suction unit which generates a suction air flow that is directed and adjusted in such a way as to controllably affect the value of said weight force detected by said at least one sensor unit;
- and
- a covering element to protect at least said at least one weighing unit and said at least one suction unit.
A filling line for filling containers, comprising
- a weighing apparatus including
- at least one weighing unit including at least one weighing device including at least one container support and at least one sensor unit which detects a value of a weight force acting on the container support;
- and
- at least one suction unit which generates a suction air flow that is directed and adjusted in such a way as to controllably affect the value of said weight force detected by said at least one sensor unit;
- a container filling apparatus;
- a container closing apparatus;
- and
- a covering and protecting structure protecting at least said weighing apparatus and including a laminar flow generating unit.
A weighing method for a filling line for filling containers of pharmaceutical, medical, food products, comprising the steps of
- weighing the containers with at least one weighing unit each equipped with at least one weighing device;
- and
- generating a suction air flow directed and adjusted to controllably affect the value of a weight detected by said at least one weighing device,
- wherein said weighing step occurs within a covering and protecting structure that contains and protects said at least one weighing unit on which the containers to be weighed are placed, and further comprising the step of generating a laminar air flow in said covering and protecting structure, said suction air flow and said laminar air flow interacting at least at said at least one weighing unit.
