  • Patent number: 8260574
    Abstract: A technique is provided for diagnosing deficiencies in a material handling system having a track and a material support member adapted to travel on the track. A diagnostic device travels with the material support member and includes one or more sensors that measure one or more parameters of the material support member. Such parameters may include an amount of force exerted laterally against one or more restraining members or the accelerations of the material support member. The material handling system may include a plurality of slats connected in an endless web that defines a conveying surface upon which articles are transported.

  • Publication number: 20120175221
    Abstract: An apparatus for selectively diverting same size articles including a conveying apparatus, a pusher device positioned proximal the conveying apparatus, at least one divergent pathway disposed transverse to the conveying apparatus and substantially opposite the pusher device, and at least one sensor positioned proximal the pusher device, wherein the sensor is operable to detect the presence or absence of an article on the conveyor apparatus and actuate the pusher device to selectively push the article to the divergent pathway. A velocity control device operates to control the flow of articles along the conveying device.

  • Patent number: 8167116
    Abstract: A method of reducing drag on the web of a positive displacement sorter is used with a web made up of a plurality of parallel slats interconnected at their opposite ends with chain assemblies in an endless loop. A plurality of pusher shoes each travel along at least one of said slats. The sorter further includes a driven sprocket assembly and a non-driven sprocket assembly. Each of the sprocket assemblies includes at least two sprockets on a shaft, each for engaging one of the chain assemblies. The sprocket assemblies support the chain assemblies at opposite ends of the web. The method includes auditing the sorter including determining if the slats are skewed with respect to the direction of travel of the web. If it is determined that the slats are skewed, then the chain assemblies and the non-driven sprocket assembly are modified. The chain assemblies are modified by adding side thrust wheels on opposite sides of the web.

  • Patent number: 7992701
    Abstract: A conveyor system aligner, method of aligning and continuous aligning belt includes providing a belt support assembly having a generally vertical support surface and a channel defined in the support surface. A belt drive propels the aligning belt along the support surface and items, such as cartons, are conveyed past the aligning belt. A continuous aligning belt is provided that has a contact portion and a guide member. The contact portion has a contact surface and a glide surface. The glide surface is configured to travel along the support surface. The guide member is adapted to be captured by the channel and travels in the channel to support the aligning belt.

  • Publication number: 20090152074
    Abstract: A conveyor diverter and method provides a device for diverting articles from a transport conveyor at increased throughput by urging a subsequent article onto the diverter before a prior article has been directed off of the diverter. The diverter raises a downstream portion of diverter surface while leaving upstream portions of the diverter surface in a lowered position, thereby permitting articles entering the diverter in a first direction to be diverted in a second direction. The diverter includes a transport conveying surface for conveying articles in the first direction and a lift assembly for raising and lowering the upstream portions and downstream portions of the diverter surface. The diverter may be configured to provide turn, cross-transfer, cross-transfer with increased throughput, and transport functions. Thus, a method is provided for achieving increased throughput and/or multiple divert functions.

  • Patent number: 7124876
    Abstract: A paddle diverter assembly according to the present invention includes an arm and an actuator for actuating the arm to move toward a diverting position. The actuator is adapted to permit the arm to move away from the diverting position upon impact with the object to be diverted and then to return to the diverting position to thereby absorb at least some of the impact between the arm and an object being diverted.

  • Patent number: 6782996
    Abstract: A conveyor roller includes at least one axle cartridge and is mounted at opposite sidewalls of a conveyor. The axle cartridge includes a bearing assembly at an outer end and an inner support at an inner end. The bearing assembly provides rotational support of a roller portion about the axle portion, while the inner support is spaced from an inner end of the axle portion during normal use of the roller. The inner support may provide contact support at the inner axle portion in response to loading induced deflection of the roller, whereby the inner support limits flexing or bending of the roller portion and may limit binding of the bearing assembly during such loading conditions. The axle portion may include one or more guide members arranged along a generally tapered or conical-shaped axle end for guiding the axle portion into a correspondingly formed opening in the conveyor sidewall.
