Assignee:

Rexnord Industries, Inc. - Milwaukee WI

International Classification:

B65G017/06

US Classification:

198853, 198845

Abstract:

A modular conveying assembly includes a conveyor belt module for use with in-line rollers. The module includes first and second hinge member. The first hinge member extends forwardly in the direction of conveyor travel, and includes a first opening defining a first space extending along an axis transverse to the direction of conveyor travel for receiving a first hinge pin. The second hinge member extends in a direction opposite to the first hinge member, and includes a second opening defining a second space extending along an axis transverse to the direction of conveyor travel for receiving a second hinge pin. A stub extends from the first hinge member transverse to the direction of conveyor travel, and surrounds at least a portion of the first space for rotatably mounting a roller thereon for rotation around the first space.

Assignee:

Rexnord Industries, Inc. - Milwaukee WI

International Classification:

B65G 17/06

US Classification:

198850, 198853

Abstract:

A modular conveyor belt having rollers for minimizing damage to the belt when transferring high friction products. The rollers are supported by easily assembled cradles that are supported between adjacent belt modules. In one embodiment, the cradles include a first part and a second part. The first part has a first hinge member and a first shaft extending from the first hinge member. The first shaft has a hollow portion opening at a first shaft distal end. The second part has a second hinge member and a second shaft extending from the second hinge member. The second shaft has a second shaft distal end received in the hollow portion of the first shaft through the first shaft distal end. In another embodiment, the roller supported by one of the cradles extends into a concave portion of an adjacent module.

International Classification:

B65G 17/24

US Classification:

198850, 198779, 198842

Abstract:

A split roller including at least two parts joined together forms the roller having a length defined between roller ends. At least two of the at least two parts are joined along a joint extending between the roller ends. A roller cradle assembly and a modular conveying assembly can be assembled including the roller.

Assignee:

Rexnord Industries, LLC - Milwaukee WI

International Classification:

B65G 17/06

US Classification:

198853, 198779

Abstract:

A modular conveying assembly for conveying an object. The assembly includes a plurality of chain modules assembled in an edge to edge relation to form a continuous belt. At least one hinge pin joins adjacent chain modules, and pivotally connects the adjacent modules in the direction of belt travel. At least one cradle adjacent at least one of the modules is retained by the at least one pin. A roller is supported by the cradle and, in one embodiment, is engageable with the object to reduce friction between the belt and the object. In one embodiment, the cradle includes a first half including a first hinge element. A second half including a second hinge element is spaced from the first hinge element and defines a space therebetween. A shaft extends between the first and second halves through the space defined by the first and second hinge elements.

International Classification:

B65G 17/06

US Classification:

198853, 198779

Abstract:

A roller cradle for use in a modular conveying assembly having a direction of travel in which an object is conveyed includes a first half and a second half. Each of the halves include integral hinge members defining a space therebetween. A roller having an axis of rotation substantially perpendicular to the direction of travel is retained in the space.

International Classification:

B65G 17/38

US Classification:

198853, 198850, 198851, 198852

Abstract:

A conveyor assembly includes a module which can support a roller between adjacent hinge members to simplify modular conveyor assembly and disassembly. The module includes at least two adjacent first hinge members extending in a direction of conveyor travel and defining a space therebetween. The at least two adjacent first hinge members include coaxial openings for receiving a hinge pin therethrough. A first snap fit extension extending from at least one of the adjacent first hinge members toward the other of the adjacent first hinge members for holding a roller in the space substantially coaxial with the openings in the at least two adjacent first hinge members.
