The vibration feeder has a drive unit (4) comprising a vibration drive (10), a carrier arrangement (5) comprising a feeding element for the material to be conveyed and a control (26) for the vibration drive (10), wherein an acceleration sensor (27) is arranged on the drive unit (10), which when the vibration feeder (25) is operating, detects the actual acceleration of the drive unit (4), and wherein the control (26) is configured to use the actual acceleration signal of the acceleration sensor (26) for generating a regulating variable for the vibration drive (10) such that the carrier arrangement (5) vibrates essentially within its resonance frequency (f.sub.res). This makes it possible, during operation, to detect the acceleration of a drive unit (4) of the vibration feeder (25) and to generate therefrom a regulating variable for a vibration drive (10) such that a carrier arrangement (5) of the vibration feeder (25) vibrates closer to its resonance frequency (f.sub.res) or is brought back again to the same. In addition the inventive control (28) may be used to also regulate the amplitude of the carrier arrangement (4) and the associated mass flow {dot over (m)} to a required value.

A container jostling system for jostling objects within a container is disclosed, where the container is positioned on a conveyor that includes a plurality of rollers that are mutually spaced from one another. The container jostling system includes at least one container contact element that is movable vertically between at least two rollers of the conveyor, and is movable horizontally in a direction that is substantially parallel with the at least two rollers.

A vibration processing apparatus (10) includes a vibration information acquisition unit (110), a reference region setting unit (120), and a determination unit (130). The vibration information acquisition unit (110) acquires detection data indicating a detection result of a vibration sensor (222). The vibration information acquisition unit (110) generates vibration information by processing the detection data. The vibration information indicates magnitude of amplitude by frequency. The reference region setting unit (120) generates data indicating a reference region set in the vibration information. The reference region indicates, by frequency, a range of amplitude in which a belt conveyor (20) is determined to be normal. When amplitude is outside the reference region at any frequency in the vibration information generated at a certain timing, the determination unit (130) determines that an abnormality occurs in a monitoring target at the timing.

A vibration generating device includes: a trough where a workpiece is placed; a first vibration motor and a second vibration motor whose rotary shafts are laid along a horizontal direction and parallel to each other; a transmission unit where the first vibration motor and the second vibration motor are arranged and that transmits a vibration of the first vibration motor and the second vibration motor to the trough; a first sensor detecting a rotating position of the rotary shaft of the first vibration motor; and a second sensor detecting a rotating position of the rotary shaft of the second vibration motor.
