An improved process and configuration for multi-function in-case filling and capping. A multi-lane embodiment is provided in which cases of empty containers are received from one or more upstream conveyor loading processes. Each case's major and minor flaps are opened, and each case is directed to flap control rails for maintaining the flaps in an open position throughout the filling and capping process. Each open case is inspected to confirm that the containers are present and are properly oriented within each case, while any improperly loaded cases are rejected from the system. The cases are then diverted into the least backlogged of a series of processing lanes, where the individual containers are filled. Screw thread caps or other closures are then applied to the containers, and the cases of filled containers converge back together in a single discharge lane. In another embodiment, an improved transfer efficiency of containers is achieved by filling the containers on the fly, and concurrent capping of multiple containers, thereby reducing the conveyor time between stations.
CROSS-REFERENCE TO RELATED APPLICATIONS
The present application is a continuation-in-part of U.S. patent application Ser. No. 09/134,599, filed May 14, 1998 now abandoned by Bennett et al. for their "MULTI-FUNCTION IN-CASE FILLING AND CAPPING SYSTEM", which application was based on U.S. provisional application serial No. 60/055,776 filed on Aug. 15, 1997.
Containers (2) having a threaded neck (3) and a mouth (4) are capped by a unit (1) appearing as a carousel (5) equipped with capping heads caused to advance along a circular path (P) and capable of axial movement toward and away from the containers in such a way that each one can be fitted with a relative cap (11); each capping head of the unit (1) incorporates a gripper (31) furnished with two jaws (30) presenting relative conical surfaces (26), and respective cylindrical surfaces (27) designed to locate against the neck (3) of the container. When the cylindrical surfaces (27) register against the outer surface of the neck (3), the conical surfaces (32) are positioned with the lower edges (28) encroaching on the area compassed by the mouth (4) in such a way that the cap (11) can be gathered and aligned with the neck (3) of the container (2) before being tightened, thereby ensuring a precise fit.
A machine for filling and closing containers comprises: a conveyor, step-activated in an advancement direction, laterally provided with a plurality of gripping devices which grip containers at an active branch of the conveyor. A filling station has a plurality of nozzles for filling the containers, and weighing devices for detecting a correct filling of the containers. A closing station has capping devices for closing the filled containers with caps, and sensors to detect correct closure. A release station, located downstream of the closing station has manipulators which are either de-activated to allow transit of incorrectly filled and/or closed containers, which are released onto a reject conveyor downstream and in line with the active branch; or activated transversally to the advancement direction to collect correctly filled and closed containers and release them onto an outlet conveyor, adjacent and parallel to the reject conveyor.
An automated system and method for emptying the contents of pharmaceutical containers. In an embodiment, a gripper unit receives and holds a pharmaceutical container. A cutter cuts the pharmaceutical container, and a rotating unit, operable with the gripper, rotates at least a portion of the gripper unit to empty the contents of the pharmaceutical container.
