Apparatus for rapid interchanging of different ramping mechanisms for capping equipment. When capping equipment is to be changed from providing roll-on closures to glass bottles to providing threaded plastic closures to plastic bottles, the positions of the bottles relative to the capping turret mechanism must be altered by changing the ramping mechanisms guiding the bottles. The ramping mechanism is maintained in position by a locking plate engaging a resilient connection connected to the rampi...

A capping device fits caps onto containers by applying an axial force to the caps as they are threaded onto the containers. The capping device utilizes a drive member rotatable about an operational axis for imparting rotation to a capper body slidably coupled to the drive member. A helical spring urges the capper body away from the drive member with a biasing force. An adjustment mechanism adjusts the biasing force thereby adjusting the axial force applied to the caps as they are threaded onto t...

A capping device fits caps onto containers by applying an axial force to the caps as they are threaded onto the containers. The capping device utilizes a spindle rotatable about an operational axis for imparting rotation to a capper unit. A connector coupled to the capper unit is releasably coupled to the spindle by a quick release mechanism. The quick release mechanism is normally biased in the locked position and is configured to automatically move from the unlocked position back to the locked...

A device for applying a cap on the neck of a bottle or similar container comprises an applying head movable along an axis and provided with an assembly for gripping the cap having a tubular body with an end mouth which is adapted to receive and hold within it the cap. Inside said tubular body is mounted freely slidable an ejector member. Stop means are provided to limit the upwards displacement of the ejector member with respect to a fixed reference when the applying head moves upwards subsequen...

An improved high-throughput system for screw-capping a continuous supply of bottles with a continuous supply of screw-caps. The system generally comprises a conveyor having opposed parallel gripper belts for ushering bottles single-file along a continuous supply and transporting them to a capping station for screw-capping (the spacing of said gripper belts being adjustable to accommodate bottles of various sizes), an adjustable-incline cap feeding chute for delivery of caps to the capping statio...

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...

An apparatus for tightening and loosening caps on containers includes a support, a rotary member mounted rotatably on the support and rotatable about a rotation axis, a complementary unit that is complementary to and that cooperates with the rotary member to define a cap passage therebetween, and a driving unit for driving the rotary member to rotate about the rotation axis. At least one of the rotary member and the complementary unit is pivotable relative to the support so as to permit passage ...

A device that is useful for applying pre-threaded closures onto threaded containers with improved sensitivity. The device allows for the adjustment of the torque that is required for capping containers such that variable sizes and variable types of containers can be capped.

Device for screwing caps onto bottles and similar containers includes a work station, which supports a device for gripping the caps and which moves toward and away from the bottles, carried by a relative feeding line. An actuator, associated to the work station, drives the gripping device into rotation, so as to screw the caps onto the corresponding open heads of the bottles. A fricton device for coupling of the actuator with the gripping device, is operated in step relation with the positioning...

A machine for attaching threaded caps to containers continuously moving in a longitudinal path and having endless belts disposed at opposite sides of the caps with the cap engaging belt portions traveling in opposite directions to impart twisting motion to the cap. The belts are moved transversely of the path into and out of engagement with the caps at a uniformed but variable rate to impose two or more pulses of twisting movement to each cap. The times of engagement and disengagement of the bel...
