| 198787000 | Rolls causes load to travel curved path | 7 |
| 20100006400 | Package stream indexer device - A package stream indexer device for indexing a stream of packages being displaced thereon within a stream plane includes a first articulated track with live rollers and a second articulated track with depending pressure wheels for maintaining packages in contact with the first track and within the package path defined there between within the stream plane. The first and second articulated tracks are each composed of a plurality of interconnected links frictionally engaged together to allow adjustment in track orientation from one set position to another by means of dynamic movement on the track. | 01-14-2010 |
| 20110089002 | POWERED ROLLER CONVEYOR SYSTEMS - A power roller conveyor system includes a section having a slide mechanism that engages a loop that is driven by an external motor. The loop slides along a surface of the slide mechanism. The slide mechanism maintains the loop in frictional engagement with surfaces of rollers of the conveyor, whereby the rollers are directly driven by the loop. A wheel may bridge a directly driven roller and another roller that is not driven. The other roller and driven roller bridged by the wheel may be separated by an intermediate roller. The section may be a straight section, a 90 degree curved section, or a 180 degree curved section. | 04-21-2011 |
| 20110114453 | PALLET CONVEYOR WITH CORNER ASSEMBLY - A twin strand conveyor uses roller chains to move pallets along straight conveyor sections and an unpowered corner assembly that enables the pallets to glide around corners of the conveyor. The pallets are transferred from an upstream conveyor section into the corner assembly using a corner injection unit that includes powered rollers that lift the pallets off the roller chains an onto a set of ball transfers that support the pallets as they glide through the corner assembly. A pickup unit having powered rollers draws the pallets off the ball transfers and onto the roller chains of the downstream conveyor section. Side guides are used to direct the pallets around the turn and onto the downstream conveyor section. One or more movable guides can be used in conjunction with a third or more conveyor sections to permit selective diverting of the pallets between the different conveyor sections. | 05-19-2011 |
| 20110120837 | PACKAGE STREAM INDEXER DEVICE - A package stream indexer device ( | 05-26-2011 |
| 20130233678 | DRIVE SYSTEM FOR CURVED ROLLER CONVEYOR SEGMENTS - A drive system for curved segments of roller conveyors and more specifically to a cost-effective, efficient, and reliable system of transferring power from a straight segment to an adjacent segment. | 09-12-2013 |
| 20140353125 | CONVEYOR AND CONVEYING METHOD - A conveyor is provided with a supply roll, a corrective holding part and an additional holding part. The supply roll rotatably supports a belt-shaped cell material for an electrode or a separator. The corrective holding part conveys and holds the cell material fed out from the supply roll while bending a first side surface of the cell material that lies against an outer peripheral side of the supply roll into a concave shape. The additional holding part conveys and holds the cell material while bending a second side surface of the cell material into a concave shape. The holding parts include a curved contact surfaces that contact opposite side surface of the cell material. The curved contact surface of the corrective holding part has a radius of curvature that is less than a radius of curvature of the curved contact surface of the additional holding part. | 12-04-2014 |
| 20150090562 | CONVEYING ROLLER UNIT, SHEET CONVEYING DEVICE, AND IMAGE PROCESSING APPARATUS - A manual sheet feeder that is an example of a sheet conveying device includes a roller unit in which a rubber roller is mounted on a support member. A separation wall is formed in an internal space of the support member, and a rotation shaft is formed at the separation wall. A slide shaft is provided such that a coil spring is interposed between the rotation shaft and the slide shaft in a compressed state. Movement of the slide shaft from an opening outward in an axial direction is restricted by an elastic engagement piece of a movement restriction mechanism. The elastic engagement piece is formed at a spring holding portion of the slide shaft. In a state where the coil spring is stored in the spring holding portion, a back surface of the elastic engagement piece is supported by the coil spring. | 04-02-2015 |
