Problems solved by technology
Explosion protection and electromagnetic compatibility often lead to considerable outlays, since the control device or controller for the vibrating feeder is often included in the central controller of the production line and can thus be up to 300 ṁ away from the vibrating feeder, which means that a corresponding cable connection is required, which requires an expensive design in terms of explosion protection and electromagnetic compatibility

Embodiment Construction
[0015] As an example, figure 1 A vibrating feeder 1 according to the prior art is schematically shown mounted on a base 2 via bearing means, in this case elastic feet or supports 3a, 3b. Visible is the drive unit 4 for the carrier device 5 which in turn has a feed element configured here as a feeder tray 6 arranged on the carrier device 5 which is filled via the The channel 7 is loaded at its rear end 8a with bulk material 9 (eg cereals, medicinal products, plastic granules and powders of various types or metal materials of various types etc.). Due to the vibratory movement of the carrier device 5 , the feeder tray 6 is also vibrated, so that the bulk material 9 is discharged from the vibrating feeder 1 at the front end 8 b of the feeder tray 6 .
[0016] The drive unit 4 comprises a vibration drive 10 configured in the illustrated embodiment as a coil carrying an alternating current, which in operation forms a periodic magnetic field and thus acts on a magnet 11 which in tur...

The vibration conveyor has a drive unit (4) which has a vibration drive (10), a support assembly (5) which has a conveyor element for material to be conveyed, and a controller (26) for the vibration drive (10). The drive unit (10) is equipped with an acceleration sensor (27) which detects the current acceleration of the drive unit (4) when the vibration conveyor (25) is being operated, and the controller (26) is designed to generate a control variable for the vibration drive (10) using a current acceleration signal of the acceleration sensor (26) such that the support assembly (5) substantially vibrates at its resonant frequency (fres), thus allowing the acceleration of a drive unit (4) of the vibration conveyor (25) to be detected during operation and a control variable for a vibration drive (10) to be generated therefrom such that a support assembly (5) of the vibration conveyor (25) vibrates more closely to its resonant frequency (fres) or is returned towards same. The amplitude ofthe support assembly (4) and the connected mass flow m can additionally be regulated to a target value by means of the controller (28) according to the invention.
Description
technical field [0001] The invention relates to a method for adjusting the vibratory movement of a vibratory feeder according to the preamble of claim 1 , and a vibratory feeder according to the preamble of claim 6 . [0002] technical background [0003] This type of vibrating feeder is used in many industries for a wide variety of materials as long as the materials can all be conveyed through the vibrating feeder. Bulk material is placed on a feed element (usually a feeder tray) which then performs a cyclic forward / upward movement with a corresponding return-vibration - whereby individual particles of material are thrown at an angle Throw forward and slightly upward at the same time. The feed element performs a return before the particles falling back rest on it again, so that when the next forward / upward movement is carried out, the particles are conveyed still further. [0004] The vibrating feeder accordingly comprises a vibrating carrier device for the replaceable fee...
