Abstract

A link is disclosed for a conveyor, as is a conveyor itself, suitable for conveying objects along a transport direction, a plurality of the links being attachable to form the conveyor, the link includes a body having a length extending along the direction of transport and a width extending across the direction of transport, and two opposed gripping members extending from the body. At least one of the gripping members is a movable gripping member movable from a first opened position to a second gripping position, the movable gripping member includes a gripping end, the gripping members being located so as to contact one of the objects via the gripping end when the movable gripping member is in the second position to hold the object relative to the body during transport. At least one spring member urging the movable gripping member toward the second position, and universal joint components are provided including an extension and a cavity, the extension being disposable in a cavity of a first adjacent link, and the cavity for receiving an extension of a second adjacent link. The extension extends along an axis substantially unaligned with the direction of transport. Various options and modifications are possible.

at least one spring member urging the gripping members toward the second position;

universal joint components including an extension and a cavity, the extension being disposable in a cavity of a first adjacent link, and the cavity for receiving an extension of a second adjacent link, the extension extending along an axis substantially perpendicular to the direction of transport; and

attaching structure for attaching the link to at least one element along the handling system.

18. The link of claim 17 , wherein the extension and the cavity are configured to form ball and socket joints capable of relative three-dimensional movement.

19. The link of claim 17 , wherein the object is a bottle having a neck, and the gripping members are configured to grip the bottle by the neck.

20. The link of claim 17 , wherein the attaching structure includes a contact member extending from the body configured for attachment to the at least one element.

21. The link of claim 20 , wherein the contact member is substantially cylindrical.

22. The link of claim 20 , wherein the cavity is located at least partially within the contact member.

23. The link of claim 17 , further including a gear drive mechanism joining the gripping members for simultaneous movement.

24. The link of claim 17 , wherein adjacent links grip conveyed objects with a predetermined spacing.

25. The link of claim 24 , wherein the predetermined spacing corresponds to a spacing of parts within the handling system.

26. A conveyor suitable for conveying objects along a transport direction, a plurality of links being attachable to form the conveyor, each link comprising:
