摘要： A contact assembly for an accumulation conveyor includes a support member having a cavity dimensioned to receive a force producing device. A contact member is positioned between the force producing device and the conveying rollers and reciprocates with respect to the conveying rollers. The contact member includes a wheel assembly which, when vertically reciprocated by the force-producing device, places the drive belt into driving contact with the conveying rollers. The wheel assembly is configured to move in a substantially transverse direction to the direction of movement of the drive belt to maintain alignment between the drive belt and the contact assembly.

摘要： An article unscrambler and aligner is disclosed which receives articles of different sizes in random order and position, and using plural side-by-side lanes each of which lanes has driven article transport rollers at different speeds, which speeds are uniform for the length of the lane, but are progressively higher in each lane toward one side of the unscrambler in order to provide a lateral linear speed increase. This speed increase causes separation and rotation of the articles and also causes them to arrange in single file along one side of the unscrambler's surface and so discharge them onto a conveyor at the end of the unscrambler remote from that at which the articles were received. One or more lanes are composed of rollers of tapered diameter in order to make the lateral speed increase more uniform.

摘要： A belt conveyor includes a driven roller and at least one other roller positioned along and between opposite sidewalls of the conveyor and a continuous belt routed around the driven roller and the other roller or rollers. The driven roller is drivable to drive the belt around the rollers to move articles along the respective zone. The belt has a low modulus characteristic and may be initially stretched at least 0.75 percent in its lengthwise direction when the belt is reeved or routed around the rollers. The driven roller may be drivable in response to an article sensor that senses articles on the conveyor belt, in order to convey or accumulate articles on the belt conveyor.

摘要： A belt conveyor or belt accumulator includes at least two tandem zones, each of which is defined by a motorized roller and at least one idler roller positioned along and between opposite sidewalls of the conveyor and a continuous belt routed around the motorized roller and the idler roller or rollers. The motorized roller is operable to drive the belt around the rollers to move articles along the respective zone. The belt may have a low modulus characteristic and may be initially stretched at least 0.75% in its lengthwise direction when the belt is reeved or routed around the rollers. The motorized roller of each zone may be independently operable, such as in response to an article sensor at each zone, to convey or accumulate articles on the respective zone of the belt conveyor.

摘要： A shaft support for supporting a shaft end of a conveyor roller is pivotable about an axis extending generally along the direction of conveyance of a conveyor, such that the support may pivot to accommodate a change in vertical positioning of one or both ends of the roller. The shaft support may also be pivotable about a generally vertical axis in order to also accommodate skewed rollers mounted at an angle not perpendicular to the direction of conveyance. Because the shaft support is pivotable about the axis extending in the direction of conveyance, the shaft support simplifies the installation and removal of the motorized roller, while providing for a roller does not require a spring loaded shaft or axle. The roller may thus be a low cost roller which may be easily installed and removed from the conveyor.
摘要翻译：用于支撑输送辊的轴端的轴支撑件可以围绕通常沿着输送机的输送方向延伸的轴线枢转，使得支撑件可枢转以适应辊的一端或两端的垂直定位的变化。轴支撑件也可以围绕大致垂直的轴线枢转，以便也容纳以不垂直于输送方向的角度安装的倾斜的辊。由于轴支撑件能够围绕沿输送方向延伸的轴线枢转，所以轴支架简化了电动辊的安装和拆卸，同时提供了一个辊子不需要弹簧加载的轴或轴。因此，辊可以是低成本的辊，其可以容易地从输送机安装和移除。

摘要： A belt conveyor includes spaced-apart opposite sidewalls and at least two rollers positioned along and between the sidewalls defining a zone in which two of the rollers are end rollers located at opposite ends of the zone. A continuous conveying belt is reeved around the rollers and defines a conveying surface between the sidewalls. At least one of the rollers is a driven roller to drive the conveying belt and move articles along the belt conveyor. The conveying belt is initially stretched lengthwise at least 0.75 percent when it is reeved around the rollers. The conveying belt is tracked around the rollers, without a take up device, by engaging with the rollers. End rollers are mounted to axles, each axle extending through and protruding from both sidewalls. Axle retainers may receive the ends the end roller axles and connect the axle ends to their respective sidewalls. The rollers may be driven in response to an article sensor that senses articles on the conveying belt, in order to convey or accumulate articles on the belt conveyor. The belt may be applied as a retrofit to an existing roller conveyor system, and the belt may be incorporated into a kit which may also include replacement end rollers and/or axle retainers for use at either end of a zone.
