A roller modular conveyor belt module for motorized continuous conveyors includes first and second hinge elements extending from a main body along opposite directions orthogonal to the first direction and spaced from each other. Each of the hinge elements has a through hole with axis parallel to the first direction and being coaxial to each other to receive a respective hinge pin. The first hinge elements are adapted to interpose to second hinge elements of another module with through holes coaxial to each other to receive a hinge pin articulating therebetween. In the space between adjacent hinge elements, there is at least one roller passed through by an axial hole arranged coaxially with the through holes of the adjacent hinge elements delimiting the space. The module includes at least one bushing having an end portion inserted in the through hole, and extending through the roller axial hole.

A conveyor for a packaging apparatus comprising a conveyor having a conveyor belt (2) with a rotatable portion (12) comprising a plurality of sub-elements (17). Each one of the sub-elements (17) comprises first annular features and second annular features. The first annular features of a sub-element mate with the second annular features of an adjacent sub-element forming a coupling seat where a pin is inserted to rotatably connect the two adjacent sub-elements. The rotatable portion (12) carries driving pieces which are put into motion by a control mechanism such that upon displacement of the conveyor belt (2) a corresponding rotation by 90° or multiples thereof is imparted to the rotatable portion (12). A packaging apparatus using the above conveyor belt is also described.

A link for a chain for an article conveyor includes first and second link elements formed as coupleable separate parts. The first link element may be configured to support articles, and the second link element may be adapted to support the first link element and to allow the chain to be moved when in use. The link includes a hinging region in the second link element for hinging the link to a further link of the chain. The hinging region may be adapted to the insertion within it of a hinging element for hinging the link to another link of the chain. The link includes confining means provided in the first link element and adapted, when the first and second link elements are coupled, to confine the hinging element within the hinging region, thereby preventing the hinging element to escape from the hinging region.

An apparatus for conveying an object in a conveying direction includes a conveyor comprised of a plurality of modular links adapted for interconnecting to form a chain. At least one of the links comprises a rounded upper portion forming an apical region for contacting and supporting the article for conveyance along at least a forward run in the conveying direction. The at least one link further including a forwardly projecting portion associated with a first transverse connector forming a part of the upper portion and a rearwardly projecting portion associated with a second transverse connector forming part of the upper portion. The first and second connectors may be staggered in the conveying direction and a direction transverse to the conveying direction. Further aspects pertain to a link with an apical engaging structure, and a sprocket with a removable tooth.

An apparatus and method of conveying parts underneath an array of inkjet printheads in such a way as to minimize print defects caused by variation in motion. The conveyor is composed of a series of rigid conveyor track segments that are forced to move in a precise straight line due to a combination of accurate ball bearing wheel assemblies and precision machine guideways that are incorporated into the conveying system.

A link conveyor for an assembly machine and methods for chordal compensation in a link conveyor, may include a first upper chordal compensation cam in the upper rail assembly at the first end of the frame to deflect the chain by a first upper variable deflection amount; a first lower chordal compensation cam in the lower rail assembly at the first end of the frame to deflect the chain by a first lower variable deflection amount; and configuring the first upper variable deflection amount and the first lower variable deflection amount to reduce deviation between a first velocity of the chain at the first end of the frame and a second velocity of the chain at the second end of the frame.

A direct drive drum (100) for a modular conveyor belt (180) comprises a drum rotation axis, a plurality of support elements (110) and a plurality of direct drive elements (120). Each support element (110) has a belt support surface (111) on a side distant and pointing away from the drum rotation axis. Each direct drive element (120) is arranged in circumferential direction (106) of the direct drive drum separate and in a distance from each of the support elements (110). In this way, the tension generated within the modular conveyor belt (180) and between the modular conveyor belt (180) and the direct drive drum (100) in a collapse phase of the modular conveyor belt (180) can be reduced.
