Abstract
A chain link conveyor formed of a number of identical plastic chain links with a number of eye-shaped hinge parts being provided in the edge of opposite sides of the individual chain links. The hinge parts are arranged so as to be coupled together with corresponding hinge parts in adjacent chain links by a common pin or pivot. On the underside, between the hinge parts, ribs extend in the conveying direction of the chain link conveyor. The ribs on the underside are configured with transverse openings or grooves so that a vacuum can distribute itself over the entire underside of the chain link when the chain link is used as a chain link vacuum conveyor.
Claims20
A chain link conveyor comprising:
- a plurality of identical plastic chain links, each of said chain links including an upper surface adapted to support items to be conveyed;
- a plurality of eye-shaped hinge parts provided at opposite ends of each of the chain links and lying beneath the upper surface, said hinge parts being adapted to be coupled together with corresponding hinge parts in adjacent chain links by a pivot, said hinge parts on the opposite sides of each chain link being staggered with respect to each other;
- ribs provided on an underside of each chain link for connecting the hinge parts lying opposite each other, said ribs extending substantially in a conveying direction of the chain link conveyor;
- and
- at least one transversely extending opening provided in at least one of said ribs for enabling an application of a uniform vacuum over an entire width of each of the chain links of the conveyor.
A chain link conveyor according to 1, wherein each hinge part has a breadth of 4-8 mm.
A chain link conveyor comprising:
- a plurality of identical plastic chain links, each of said chain links including an upper surface adapted to support items to be conveyed;
- a plurality of eye-shaped hinge parts provided at opposite ends of each of the chain links and lying beneath the upper surface, said hinge parts being adapted to be coupled together with corresponding hinge parts in adjacent chain links by a pivot, said hinge parts on the opposite sides of each chain link being staggered with respect to each other;
- ribs provided on an underside of each chain link for connecting the hinge parts lying opposite each other, said ribs extending substantially in a conveying direction of the chain link conveyor, and
- wherein the at least one transverse opening is fashioned as one of a groove or recess in an edge of the at least one rib, which edge faces away from the upper surface.
A chain link conveyor comprising:
- a plurality of identical plastic chain links, each of said chain links including an upper surface adapted to support items to be conveyed;
- a plurality of eye-shaped hinge parts provided at opposite ends of each of the chain links and lying beneath the upper surface, said hinge parts being adapted to be coupled together with corresponding hinge parts in adjacent chain links by a pivot, said hinge parts on the opposite ends of each chain link being staggered with respect to each other;
- ribs provided on an underside of each chain link for connecting the hinge parts lying opposite each other, said ribs extending substantially in a conveying direction of the chain link conveyor, and
- at least one transversely extending opening provided in at least one of said ribs,
- wherein, with the exception of the outermost ribs provided at the respective lateral edges of each chain link, each remaining rib is provided with at least one transverse opening,
- wherein the plurality of hinge parts are arranged across a breadth of the chain link, and
- wherein the ribs extend in pairs from a hinge part at one end of the chain link to adjoining hinge parts provided at the opposite end.
