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.

A method for checking the functionality of a vibratory conveyor device (1) by means of a status analysis which is carried out either before operation or during operation of the vibratory conveyor device (1), wherein A) the method to be carried out before operation comprises the following steps: A1) applying a drive pulse to a drive device (2) of the vibratory conveyor device (1); A2) detecting the pulse response caused by the vibratory conveyor device (1); A3) passing on the detected pulse response by way of the signal evaluation unit (5) to a computer (6); A4) comparing the detected pulse response to a reference pulse response by means of the computer (6); and A5) ascertaining by means of the computer (6) whether: a) a starting procedure for operation with reduced starting drive power of the vibratory conveyor device (1) is to be activated, or b) a starting procedure for operation without reduced starting drive power of the vibratory conveyor device (1) is to be activated, or c) the operation is to be suspended; B) the method to be carried out during operation comprises the following steps: B1) detecting the voltage amplitude, frequency, acceleration, and temperature, caused by the vibratory conveyor device (1), in operation of the vibratory conveyor device (1) by means of the signal evaluation unit (5); and B2) passing on the detected voltage amplitude, frequency, acceleration, and temperature by way of the signal evaluation unit (5) to a computer (6).

A conveyor includes a trough with a floor having an upper surface configured to receive items to be conveyed in at least a first direction from a first end to a second end. The conveyor also includes a platform with at least one exciter attached thereto. The at least one exciter has at least one shaft with an eccentric mass attached thereto, the shaft having an axis of rotation about which the mass is rotated. The conveyor also includes a base. At least one first toroidal resilient member is disposed between the trough and the platform, and at least one second toroidal resilient member disposed between the platform and the base.

A parts accumulating section includes a cylindrical center member; and a hose helically wrapped around the outer periphery of the cylindrical center member, and connecting two predetermined steps of a parts production line to each other. The hose has an inner diameter dimension which enables parts to pass, in a predetermined attitude, through the hose with only a respective one of the parts disposed in the hose in the radial direction of the hose. A vibration generating section applies torsional vibrations to the parts accumulating section so that the parts are fed through the hose. The parts discharged from the upstream step are accumulated in the hose in the same order as they are handled in the upstream step. The parts are fed through the hose without generating surface damage to the parts due to their collision against each other, and are supplied to the downstream step.
