A stacking system for aligning and stacking stamped sheet metal parts is provided. The stacking system includes a frame configured to coordinate a plurality of sub-systems including a parts catcher, receiving head including a plurality of alignment cylinders, and a set of elevating tables on a shuttle platform. Parts are received by the catcher from a conveyor belt and transported to a receiving head for alignment to a targeted position. After the formed part is aligned to the stack, the lift table is lowered such that space is available for another part to be aligned. After a predetermined number of formed parts has been stacked, a table shuttle will slide the lift table to an unloading position accessible by a fork truck.

A turning driving device includes a directional motor, and a wheel hub motor module and a driving device disposed above and below the directional motor, respectively. The directional motor includes a rotation shaft, and the wheel hub motor module includes a fixing frame, and a roller rotatable about a horizontal fixed axle. The fixing frame is mounted with the fixed axle, and the rotation shaft is combined with a bottom of the fixing frame. The driving device includes a control module electrically connected to the directional motor and the wheel hub motor module. When the control module outputs and transmits a control signal to the directional motor and the wheel hub motor module, the rotation shaft drives the fixing frame to horizontally turn to a preset angular position, and the roller is driven to vertically rotate to drive the article to move toward a predetermined direction.

A raised belt transfer unit may comprise a first angled support and a second angled support, a drive roller rotatably mounted to the first angled support and the second angled support, a plurality of driven rollers rotatably mounted to the first angled support and the second angled support, and a drive connecter in communication with the drive roller and a driven roller. The drive roller may be positioned adjacent a lower end of the first support and adjacent a lower end of the second support. The drive roller may be adapted to be coupled to a conveyor belt of a telescopic conveyor.

Some embodiments of the technology disclosed herein relate to a sensor device. An elongate sleeve has a first end and a second end and extends along a longitudinal axis. A plurality of sensors are fixed relative to the sleeve. A first endcap is coupled to the first end, where the first endcap has an endcap body. A first axle is coupled to the endcap body, where the first axle extends along the longitudinal axis and the first axle defines a retaining feature. An intermediate component is coupled to the first axle, and the intermediate component is selectively rotatable about the longitudinal axis. The sensor device has an orientation locking structure that is configured to be engaged to selectively fix the orientation of the intermediate component about the longitudinal axis relative to the endcap body.

A roller plate assembly includes a base plate having a plurality of openings distributed along a length and a width of the base plate. The roller plate assembly includes at least two cross supports coupled to the base plate. The roller plate assembly also includes a roller shaft extending at least partially through the at least two cross supports and a plurality of rollers rotatably mounted to the roller shaft. Each roller is disposed within a corresponding one of the plurality of openings and configured to project at least partly over the upper surface of the base plate. The plurality of rollers are configured to allow a package to move across the plurality of rollers from a first edge of the roller plate assembly to a second edge of the roller plate assembly in the length direction of the base plate.
