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.
Claims23
An axial feed system for logs, comprising:
- a support having a through opening;
- a plurality of supporting arms pivotably mounted to the support on corresponding shafts such that the supporting arms are pivotable between a home position and a work position, wherein the supporting arms are configured to support corresponding rotatable feed cylinders in an angular distribution around a center axis of the through opening;
- a plurality of links pivotably coupled with the supporting arms, and with each other, such that the links are collectively operable to force the supporting arms to pivot jointly about the corresponding shafts, 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;
- and
- a motion damper with opposite first and second ends, the first end pivotably attached to the first link at a second portion of the first link and the second end pivotably attached to the second link at a second portion of the second link, such that the second portions of the first and second links are connected by the motion damper, wherein the motion damper is configured to brake return movement of the supporting arms to the home position.
A feeding device for feeding a log axially in a flow direction, comprising:
- a support having a through opening and feed cylinders adjoining the opening, wherein the feed cylinders are angularly distributed and individually arranged in a free end of a respective supporting arm and driven in rotation, and wherein the supporting arms in a supported end are journalled in the support on corresponding shafts extending in parallel with each other, and the supporting arms 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 forced to pivot jointly about their respective shafts, wherein the links include 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;
- and
- a movement damping element configured to brake the return movement of the supporting arms to the home positions, wherein the motion damper has opposite first and second ends, the first end is pivotably attached to the first link at a second portion of the first link and the second end is pivotably attached to the second link at a second portion of the second link, such that the second portions of the first and second links are connected by the motion damper.
