Modular Conveyor Belt
US Patent:
6705460, Mar 16, 2004
Filed:
Apr 23, 2002
Appl. No.:
10/127448
Inventors:
David C. Weiser - River Ridge LA
Andrew A. Corley - River Ridge LA
Andrew A. Corley - River Ridge LA
Assignee:
Laitram L.L.C. - Harahan LA
International Classification:
B65G 1706
US Classification:
198850, 198853
Abstract:
A module for a modular conveyor belt has a plurality of projections on its top surface for supporting objects. The module may include drainage openings through which fluids can drain from objects disposed on the projections. The projections can be used to prevent objects from adhering to the top surface of the module and/or to immobilize the objects during movement of a conveyor belt including the module.

International Classification:
B65G017/06
US Classification:
198851, 198850, 198852, 198853, 244 33 R
Abstract:
A modular plastic conveyor belt hingedly interconnected by hinge pins made of a highly oriented polymer material. The hinge pins are preferably extruded from a material including a highly oriented polymer, such as polyethylene, polypropylene, or nylon. Alternative materials include highly oriented acetal or polyurethane. Plastic hinge pins made with these polymers having their long molecules oriented along the axis of the shaft of the hinge pin are exceptionally strong and resistant to deformation.

International Classification:
B65G 17/24, B29C 45/14
US Classification:
198779, 264255
Abstract:
A modular roller-top conveyor belt and rollers for the belt. The roller-top belt has axles that are fixed relative to the module body. Each of the pieces of the multi-piece rollers can be installed radially onto an axle and joined together in a puzzle pattern to form a complete roller that can rotate on the axle. Parallel ridges extending across the width of the modules add stiffness to the belt.
Modular Conveyor Belts With Split Belt Modules
US Patent:

International Classification:
B65G 17/24
US Classification:
198853, 198850
Abstract:
Modular plastic conveyor belts constructed of split belt modules. Each module includes a first piece and a second piece. Side-by-side first pieces mate with side-by-side second pieces to form a row of belt modules. Each row has sets of hinge eyes along opposite ends. Hinge pins extending through the hinge eyes at the ends of each row connect the pieces in the row together to adjacent belt rows. Other components, such as rollers, can be inserted into and removed from the unmated pieces and retained in place by retention structure when the module pieces are mated.
Transverse-Roller Belts And Modules
US Patent:
7540368, Jun 2, 2009
Filed:
May 1, 2007
Appl. No.:
11/742614
Inventors:
David C. Weiser - River Ridge LA, US
Assignee:
Laitram, L.L.C. - Harahan LA
International Classification:
B65G 17/06, B65G 17/24
US Classification:
19837009, 198779, 198853
Abstract:
A modular roller-top conveyor belt with a dense array of rollers freely rotatable toward the sides of the belt. The rollers are arranged in offset lines and columns in a checkerboard pattern on the top side of the belt. The rollers rotate on axes parallel to the direction of belt travel. The rollers extend in the direction of belt travel over the hinge axes formed between adjacent rows of belt modules.

A modular roller-top conveyor belt and multi-piece rollers for the belt. The roller-top belt has axles unitarily molded with the belt modules. Each of the pieces of the multi-piece rollers can be installed radially onto an axle and joined together in a puzzle pattern to form a complete roller that can rotate on the axle. Parallel ridges extending across the width of the modules add stiffness to the belt.
Conveyor Belt And Module Accommodating Rod Growth
US Patent:

Gilbert J. MacLachlan - Harahan LA, US
Assignee:
Laitram, L.L.C. - Harahan LA
International Classification:
B65G 17/08
US Classification:
198853
Abstract:
A modular plastic conveyor belt that is useful in accommodating hinge rods that tend to lengthen during use and an edge module for constructing such a belt. An edge portion of the edge module has an elongated link end that provides an unimpeded growth path for a hinge rod within the confines of the belt. The edge portion of one edge module is hooked to the edge portion of an adjacent edge module by a pivot that is pivotally received in a mating receptacle on the adjacent module.
