A sealing machine and method for controlling a sealing machine Includes the following steps: placing capped containers provided with a seal on plates, rotating the plates, pressing the seal against the cap of the container and fastening said seal using a sealing head. The step of rotating the plates is performed by rotating each plate independently of the other plates. The method further includes: detecting at least one parameter associated with the rotation of a plate and/or with a compression load between each sealing head and the seal, and comparing the value of the detected parameter with a reference range.

A bearing arrangement for the mounting of a container processing carousel with respect to a base frame of a container processing apparatus in a beverage filling installation, comprising including a bearing shaft which extends along a longitudinal axis, a bearing cup which is rotatable relative to the bearing shaft, an adjusted bearing assembly, arranged between the bearing shaft and the bearing cup, for the mounting of the bearing cup with respect to the bearing shaft, and a ring-shaped preload unit for imparting a specified preload to the adjusted bearing assembly, wherein the ring-shaped preload unit includes a multiplicity of spring assemblies, which are distributed uniformly in a circumferential direction about the longitudinal axis, for applying the preload to the adjusted bearing assembly. A container processing apparatus including the bearing arrangement, and a method for preloading an adjusted bearing assembly of the bearing arrangement are described.

Transfer star-wheel (1) of containers (100) made of thermoplastic material provided with concave closures (200), comprising: a rotary carousel (2) having a plurality of supporting stations (3) for supporting the containers (100), each supporting station (3) comprising a pocket (4) at the external circumference of the rotary carousel (2) for receiving and supporting the neck (100b) of one of the containers (100), characterized in that each supporting station (3) comprises a striking element (5) located above the corresponding pocket (4), said striking element (5) being configurable in an operative position in which it is in contact with the concave closure (200) of the container (100) supported in the corresponding pocket (4), and a neutral position in which it is spaced from the concave closure (200).

A capping machine includes a gripper having a pair of gripping arms provided on an outer peripheral portion of a rotating body and configured to grip a cylindrical portion of a vessel, an opening and closing device configured to open and close the gripping arms, and a capping head liftably and rotatably provided on the rotating body. The gripping arms are arranged symmetrically with respect to a radius of the rotating body. The gripper has a protrusion for preventing the vessel from rotating on a vessel gripping surface of the gripping arms. The gripping arms have outer and inner gripping surfaces which are connected in a V shape. The protrusion is formed only on the inner gripping surface of a right gripping arm. A cap held by the capping head is screwed onto the vessel while sticking the protrusion into the cylindrical portion.

Methods and systems for capping prescription medication bottles are provided. In one embodiment, a capping system is provided that includes a first position at which uncapped bottles containing fulfilled prescriptions are received. The capping system also includes a second position at which uncapped bottles are capped. The second position may include a capping member that is axially aligned with a vertical centerline of uncapped bottles located at the second position. The capping system may also include an index wheel configured to support bottles within the capping system. The index wheel may be rotatable to convey uncapped bottles from the first position to the second position. The capping system may further include a cap track that provides caps to the capping member.

A capping chuck assembly having a chuck housing, a retaining assembly and a cap gripping assembly. The chuck housing receives a cap and has longitudinal axis of rotation. The retaining assembly includes a plurality of retaining jaws and a biasing member. The retaining jaws are movable radially, with biasing member inwardly biasing the jaws. The cap gripping assembly includes a plurality of gripper assemblies spaced apart from each other about the axis. Each gripper assembly has a cam arm rotatably mounted to the chuck housing with a lever arm portion extending toward the axis of rotation configured to rotate relative to the cap receiving opening. An engaging jaw is coupled to the gripper assembly. Rotation of the cam arm away from the cap receiving opening directs the engaging jaw radially toward the axis of rotation. An ejection assembly is disclosed as well as a method of retaining a cap.

The present invention concerns a motion transmission group for capping heads for screw caps. This group comprises a device for applying in use a predefined axial load to means of axial engagement of the caps which a capping head associated in use with said group is provided with. The device comprises at least one axially pre-loaded compression spring so as to generate in use this predefined axial load. The device is separable from the main structure of the transmission group as a single body, with the aforesaid at least one spring maintained associated with a support structure of the device in pre-loaded condition by means of two axial positioning portions to allow the replacement of the device with a structurally similar device, but suitable to generate in use a different axial load.

A capping machine includes a gripper having a pair of gripping arms provided on an outer peripheral portion of a rotating body and configured to grip a cylindrical portion of a vessel, an opening and closing device configured to open and close the gripping arms, and a capping head liftably and rotatably provided on the rotating body. The gripping arms are arranged symmetrically with respect to a radius of the rotating body. The gripper has a protrusion for preventing the vessel from rotating on a vessel gripping surface of the gripping arms. The gripping arms have outer and inner gripping surfaces which are connected in a V shape. The protrusion is formed only on the inner gripping surface of a right gripping arm. A cap held by the capping head is screwed onto the vessel while sticking the protrusion into the cylindrical portion.

Apparatus for engaging a cap releasably secured in a container includes a carrier that is selectively movable up and down relative to the container and carries a cap engagement tool and a centering collar. At least one among the cap engagement tool and centering collar is biased downwardly by at least two spaced-part biasing members during operations.
