The shuttle conveyors may include a track extending along a conveying path, the track defining a length, and a plurality of shuttle elements independently movable along the track. Each shuttle element may define mating structure for following the track along the conveying path. Each shuttle element may include at least one movable gripping member for selectively gripping conveyed objects. The shuttle elements may define a collective length less than the length of the track. A drive mechanism moves the shuttle elements along the track. The shuttle elements may include a plurality of links. The shuttle elements may be driven faster on at least a portion of a return portion of the track than on the conveying portion of the track, and the shuttle element flow along the track may be modulated in various ways.
Abstract:
A conveyor is disclosed suitable for conveying objects such as containers to a processing station. The conveyor includes a plurality of connected links, and at least one gripping member extending from each of the links. Each gripping member is movable relative to its respective link for gripping a container by the neck of the container. A guide structure is disposed on the link for mating a component of the processing station to the neck of the container for processing the container. The processing station may be a filler such as a rotary filler, a capper, or a rinser. Related individual links, conveying systems, and filler components are also disclosed.
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:
The present invention provides a packaging apparatus for gripping, lifting, and then moving a plurality of individual products from a first location to a second location. The apparatus includes first and second plates and a plurality of individual grippers that are each selectively actuated to grip a single product and to release the product at a preselected time. Each gripper includes a plurality of slots extending upwardly from the base of each gripper, thereby providing a plurality of gripper fingers. Each gripper extends through an appropriately configured hole in the second plate into a fixed engagement with the first plate. The second plate is movably mounted to the first plate such that it can be moved relatively thereto. The holes in the second plate are sized to engage the gripper fingers when moved apart from the first plate. As the plates continue to move apart, the continuing camming engagement between the second plate and the gripper will cause the gripper fingers to be moved inwardly into a gripping engagement with the products.
Abstract:
A conveying device with a diverter is disclosed 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 established by a first guide unit to different ones of plural second paths established by a plurality of second guide units through a third path established by a third guide unit having a diverter to align a first end of the third path with the first path and to move the second end of the third path for alignment with the different ones of the plural second paths with a deviation in the third path between the ends thereof being established during aligning movement of the second end of the third path by flexing of a flexible bar positioned adjacent to the third path. A controller is utilized to control movement of the diverter to align the second end of the third path with different ones of the second paths, and the unstable articles are supported by flanges extending from chains in actuating guides positioned at opposite sides of the article paths and movable along the guides to urge the unstable articles along the article paths.
Abstract:
A conveyor chain includes chain links connected by connecting pins. Each chain link is provided with a bottle conveyor member attached to a main offset link member having a pin link, a bushing, and a conveyor member attachment plate of a synthetic resin or plastics. The conveyor chain is supported by sprocket wheels and chain guidance members to configure a conveyor chain apparatus. The arrangement is such that a pair of the conveyor chain apparatuses are disposed on each side of a conveyor path for bottles and also a holder ring provided at a mouth portion of a bottle is held from both sides by the bottle conveyor members. The conveyor chain apparatus is configured so that bottles are conveyed thereby in a state suspended from neck portions thereof.
Abstract:
A device for conveying empty bottles in a hanging arrangement applicable to the conveyance of bottles made of plastics material, the bottles including a flange in the region of their neck, the flange being partially introduced and guided in lateral channels whose open sides face each other, the flange resting on the lower edge of the respective channel and being in a position to slide along the channels, outlets for insufflating pressurized air from lateral ducts having been provided inside the channels. Above the path traced by the necks of the bottles extends a duct which opens onto the path at a slot and is connected to a suction device that generates a negative pressure.
Abstract:
An air conveyor transitional section connects an upstream air conveyor section to a downstream air conveyor section that is not collinear with the upstream air conveyor section. The air conveyor transitional section includes a pair of elongated members having opposed inner edges and upper surfaces adjacent the inner edges. The inner edges of the elongated members are laterally spaced to define a slot that extends in a downstream direction of the air conveyor. The upstream air conveyor section, the transitional section, and the downstream air conveyor section are all configured for conveying containers in the downstream direction. Each container has a neck ring with an outer diameter dimension. The inner edges of the elongated members are laterally spaced by a distance smaller than the container neck ring outer diameter dimension so that the upper surfaces provide slidable support for the container neck rings. The pair of elongated members of the transitional section has a continuous curve that extends without interruption substantially from a downstream end of the upstream air conveyor section substantially to an upstream end of the downstream air conveyor section. At least a portion of the pair of elongated members extends curvilinearly in a vertical plane so that a height of the containers varies vertically as the containers are conveyed in the downstream direction through the curvilinearly extending portion of the pair of elongated members. Thus, the transitional section defines a substantially continuous conveying path connecting the upstream and downstream air conveyor sections.
