Vibratory conveyor

A vibratory feeder comprising a support arrangement carrying out a vibrational movement when in operation for a feeder element in which material to be fed is fed, a drive arrangement for the support arrangement and a bearing arrangement which introduces the vibrational oscillations of the vibratory feeder in a reduced manner into a base wherein means are provided which, during operation of the vibratory feeder suppress a deviation of the vertical component of the vibrational movement of a front end of the feeding element from that of a rear end,

• wherein the means for suppressing the deviation have a combined spring unit comprising a link provided in each case in the vibrational movement arrangement and the bearing arrangement, and a support member provided in the drive arrangement and extending over a height and inclined with respect to the vertical substantially at a throwing angle, wherein the links extend along the support member on different sides thereof, and wherein the link of the vibrational movement arrangement is fixed to the support member in a lower region thereof and extends upwards, the link of the bearing assembly is fixed to the support member in an upper region thereof and extends downwards, whereby the upper end of the link of the vibrational movement arrangement is fixed to the support arrangement and the lower end of the link of the bearing assembly is fixed to the ground.

A vibratory feeder comprising a support arrangement carrying out a vibrational movement when in operation for a feeder element in which material to be fed is fed, a drive arrangement for the support arrangement and a bearing arrangement which introduces vibrational oscillations of the vibratory feeder in a reduced manner into a base wherein means are provided which, during operation of the vibratory feeder suppress a deviation of the vertical component of the vibrational movement of a front end of the feeding element from that of a rear end,

• wherein the means for suppressing the deviation have an arrangement of a center of gravity of the support arrangement, preferably with the feeder element resting thereon, and of a center of gravity of the drive arrangement on a straight line in the direction of a throwing angle, wherein the direction of the straight line preferably deviates from the throwing angle by 20° or less, particularly preferably by 10° or less,
• wherein the means for suppressing the deviation further comprise a bearing arrangement having two spring-elastically operating bearing units spaced apart from one another in the feeding direction, which are supported on the base and engage on the drive arrangement in bearing points, wherein each bearing unit is operative in horizontal and vertical directions with the same spring constant, and the straight line in the direction of the throwing angle intersects a connecting line between the bearing points substantially in the middle thereof.
