Abstract
Abstract A modular positive drive, high-speed response, diverting conveyor unit, which includes a support structure for continuously driving the rollers. There is a main direction control device for operating the drive apparatus to drive the rollers to convey selectively in a forward and reverse direction. There is a support frame and a mounting structure carried on the support structure for slidably supporting the support frame; a dynamic roller conveyor has parallel sets of raised and laterally spaced flights and a drive chain section; a drive system mounted on the support frame continuously drives the roller conveyor; a transverse direction control device operates the drive system to drive the roller conveyor to convey selectively in the left and right directions; an actuator mounted on the support structure moves the support frame selectively up to insert the flights interstitially of the rollers to divert the conveyed goods from the main direction and down to withdraw the flights and allow the goods to continue in the main direction.

Claim 1
Independent Claim
204 words
A modular positive drive high-speed response diverting conveyor unit comprising: a support structure; a static conveyor including a plurality of spaced rollers mounted in said support structure; a drive apparatus disposed within said support structure for continuously driving said rollers; a main direction control device for operating said drive apparatus to drive said rollers to convey selectively in the forward and reverse direction; a support frame and a mounting structure carried on the support structure for slidably supporting said support frame; said mounting structure including spaced slides for slidably receiving a slide member carried by said support frame; a dynamic roller conveyor having parallel sets of raised laterally spaced flights and a drive chain section carried by said support frame; a drive system mounted on said support frame for continuously driving said roller conveyor; a transverse direction control device for operating said drive system to drive said roller conveyor to convey selectively in the left and right directions; and actuator means mounted on said support structure for moving said support frame selectively up to insert said flights interstitially of said rollers to divert conveyed goods from the main direction and down to withdraw said flights and allow goods to continue in the main direction.
