A vibratory tablet feeder includes a reservoir for storing a supply of tablets with a pathway that leads to an exit opening for discharging tablets therefrom. Vibration of the reservoir moves tablets as a flow of tablets along the pathway to the exit opening. The feeder can include a wiper spaced vertically from the pathway. The wiper has a wiping surface that is configured to guide at least one vertically-bunched tablet in the flow of tablets away from the exit opening for return to the reservoir in order to provide singulated flow of tablets at the exit opening. A portion of the pathway may define a chamfered edge that is configured to guide at least one horizontally-bunched tablet in the flow of tablets away from the exit opening for return to the reservoir in order to provide singulated flow of tablets at the exit opening.

Methods and systems for controlling a vibratory feeder are disclosed. In some embodiments, the methods and systems include the following: a controller module including a graphical user interface for selecting operating parameters to be communicated to a bowl drive that causes a feeder bowl to move, monitoring algorithms stored in non-transitory memory for processing motion data to monitor motion of the feeder bowl, and adjustment algorithms stored in non-transitory memory for determining and automatically adjusting the operating parameters, and a motion sensor module configured to mount with and sense motion of the bowl drive, the motion sensor module including an accelerometer, a digital signal processor (DSP) microcontroller, and a transmitter. The DSP microcontroller samples output data from the accelerometer, determines motion data of the motion of the bowl drive, and transmits the motion data via the transmitter to the controller module.

Raw material devices, systems that incorporate raw material delivery devices, and methods of supplying raw material using the raw material devices. A raw material delivery device includes a hollow body comprising a first end and a second end, the second end disposed above the first end in a system vertical direction, an inlet disposed at the first end of the hollow body, an outlet disposed at the second end of the hollow body, and a stepped passageway disposed within the hollow body between the inlet and the outlet. The stepped passageway is configured to deliver raw material via one or more steps from the inlet to the outlet.

The present application discloses vertical spiral conveyors for transporting loose material without the use of vibration or oscillation and methods of transporting materials without the use of vibration or oscillation. In certain embodiments, the vertical spiral conveyor comprises a vertical spiral fabrication having a spiral conveyor tray connected to a vertical member that is configured to rotate about an axis of rotation, a drive arm extending from the vertical spiral fabrication, and a drive system for rotating the vertical spiral fabrication about the axis of rotation. The drive system comprises a power source and a transmission coupled to the drive arm. The drive system generates alternating forward and backward strokes on the drive arm that rotate the vertical spiral fabrication clockwise and counterclockwise about the axis of rotation to cause loose material to be conveyed around the spiral conveyor tray.
