Abstract:
An apparatus for supporting a preform is provided. The apparatus comprises a shaft defining a groove. A deformable element is arranged in the groove. A split ring having at least two pieces is provided. Each of the pieces has an inner surface facing the deformable member and an outer surface. At least one of the pieces has a protrusion extending from its inner surface. The protrusion is arranged adjacent to the deformable element and the split ring being moveable in a radial direction whereby the protrusion causes the deformable element to be compressed in the groove.
Abstract:
A link is disclosed for a conveyor suitable for conveying objects along a transport direction. The link includes a body having a length extending across the direction of transport and a width extending along the direction of transport. The body has a conveying surface and two opposed gripping members extending from the conveying surface. Each gripping member is movable from a first opened position to a second gripping position. The gripping members each include a gripping arm configured to be pivotable relative to the conveying surface when the gripping members move from the first position to the second position. The gripping arms are located so as to be able to contact one of the objects when the gripping members are in the second position to hold the object relative to the link during transport. The link includes at least one spring member urging the gripping members toward the second position. Various other related options are disclosed, along with related conveyors.
Abstract:
A conveying device with a diverter having a curved path for conveying lightweight unstable articles, such as plastic bottles having a neck portion with a neck ring thereon. The unstable articles are conveyed along a first path to different ones of plural second paths through a third path at the diverter with the third path having first and second ends alignable with the first path and different ones of the plural second paths and a middle portion maintained in a curved configuration that is varied during aligning movement of the second end. A controller controls the aligning movement of the second end, preferably along a straight path, and the unstable articles are supported by engaging members in actuating guides to urge the unstable articles along the article paths.
Abstract:
An pneumatic tensioner apparatus is disclosed, the apparatus including: a main drive belt; a chuck assembly, suspended from the main drive belt, having a spinning member and a drive contact portion; a first frictional drive belt in a first track, the first frictional drive belt in contact with the drive contact portion operative to spin the chuck assembly; and a first tension adjusting device having at least one pneumatic tension adjustment member operative to apply pressure to the first frictional drive belt tangentially to the drive contact portion.
Abstract:
A selective conveying device is disclosed for conveying unstable articles, such as plastic bottles, having a neck portion with a neck ring thereon. Neck ring supported unstable articles are conveyed in single file along an article conveying path established by first and second guide units with the guide units having spaced connectors with neck ring engagable elements thereon spaced different distances from one another to receive the neck portions of unstable articles having different size neck portions. A first actuator, such as a pneumatic or mechanical actuator, causes relative movement between the guide units so that unstable articles are conveyed along the article conveying path on the neck ring engagable portions of the first guide unit when in a first operating position or are conveyed along the article conveying path on the neck ring engagable portions of the second guide unit when in a second operating position. The unstable articles are urged along the article conveying path by a second actuator, such as an air conveyor and/or a movable belt.
Abstract:
Disclosed is a device for intermittently conveying packages which are conveyed in a first moving direction in package carriers (2) in a first processing plane in positions underneath various treatment stations and are conveyed back in a second return motion plane in a second moving direction that is parallel in relation to the first moving direction, whereby a conveying cycle is formed. The aim of the invention is to enable such a device to be efficient, compact and be operated using simple devices. According to the invention, the respectively superimposed ends of the essentially horizontal first conveyor (19) in the first processing plane and of the essentially horizontal third conveyor (12) in the second return motion plane are connected to one another for forming the conveying cycle by means of vertically acting second and fourth lifting conveyors (9, 15). Each conveyor (9, 19, 12, 15) has a separate drive (22-24). A third loading plane is arranged between the first processing plane and the second return motion plane. The three planes are arranged in an essentially horizontal manner. Each package carrier (2) is constructed in an even manner and is held in a horizontal position by means of the conveyor cycle. Means for loading and unloading the packages into and/or from the package carriers (2) are provided in the region of the third loading plane in a loading direction which is parallel in relation to the first moving direction of the packages.
Abstract:
Apparatus and method for conveying articles, particularly articles such as containers, or bottles, having a neck portion with a neck ring thereon, along an article conveying path with the articles being urged along the article conveying path by article engaging members extending from a plurality of sections of an elongated movable member that extends from a guide along a guide path adjacent and horizontally offset from the article conveying path. The elongated movable member is preferably a chain having a plurality of links and article engagement preferably includes a flange that extends horizontally from each chain link into the article conveying path with adjacent flanges spaced from one another in the article conveying path whereby the chain links and flanges extending therefrom enable limited angular deviation of the chain during normal operation with the flanges engaging the lower edge of the neck ring of articles in the article conveying path so that the articles are urged along the article conveying path upon movement of the chain unit along the guide path.
Abstract:
A guide is employed on air conveyors of the type that suspend conveyed objects from an intermediate enlargement, for example, conveying plastic bottles by suspending the bottles from their neck rings, where the guide limits the upward movement of the bottles conveyed by a conveyor system preventing the bottles from becoming wedged in the air conveyor and jamming the flow of bottles through the air conveyor while permitting each of the bottles conveyed to swing freely forwardly and rearwardly from their neck rings as the bottles are conveyed through the conveyor.
Abstract:
The apparatus comprises a cylinder housing a rotary scroll Tubular preforms are fed into the cylinder in an upright state and displaced along the cylinder by a fin of the scroll. A spring mounted on the fin engages each preform in turn and inverts it. The inverted preforms are then driven over a series of nozzles discharging ionised gas to purge the preforms of debris. The preforms are then discharged.
Abstract:
An improved ledge support assembly for a filling machine for filling containers is provided. The ledge support assembly supports and retains the containers in the machine during movement through the machine. The ledge support assembly includes a pocket support portion for holding the neck portion of a bottle and a back support portion for supporting the container body portion of a bottle in a single position during rotation. A locking mechanism is provided on the pocket support and a second locking mechanism is provided on the back support for releasably attaching each of the pocket support and the back support to the ledge support assembly.
