Abstract
In various embodiments, a feeding device may comprise a support having feed cylinders arranged in a free end of a respective supporting arm and driven in rotation, wherein the supporting arms in a supported end are journalled in the support on shafts extending in parallel with each other and are pivotable about the shafts between a home position and a pivoted work position, and wherein the supporting arms are mutually connected to each other via a system of articulated links and by means of the links are forced to pivot jointly about their respective shafts, and a movement damping element, which is separate from the support, is integrated in the system of links and independently from the support configured to brake the return movement of the supporting arms from the pivoted position.
Claims17
A method of modifying a log feeding device, wherein the log feeding device includes a support having a through opening, a plurality of supporting arms pivotably mounted to the support on corresponding shafts and supporting corresponding rotatable feed cylinders arranged in an angular distribution around a center axis of the through opening, and a plurality of links pivotably coupled with the supporting arms and with one another, such that the links are collectively operable to move the supporting arms between a home position and a pivoted work position, wherein the plurality of links includes a first link and a second link, and the first and second links are pivotable about a first pivot axis that extends through a first portion of the first link and a first portion of the second link, the method comprising:
- pivotably coupling a first end of a motion damper to the first link at a second portion of the first link;
- and
- pivotably connecting an opposite second end of the motion damper to the second link at a second portion of the second link, such that the motion damper extends between the second portions of the first and second links.
