Abstract
Apparatuses, systems, and methods for debarking logs are shown and described. The disclosed embodiments can be used for quickly and conveniently replacing contact surfaces, such as leading edges, of swing arm assemblies. Some disclosed embodiments include a swing arm assembly having a replaceable insert that defines a leading edge for engaging logs moving along a processing line. The insert can be made of a wear resistant material for a prolonged life. A worn insert can be replaced with another insert to ensure proper functioning of the debarker.
Claims17
An apparatus for removing bark from a log, the apparatus comprising:
- a rotatable carriage having an opening sized to receive a log moving along a processing line passing through the opening;
- and
- a swing arm assembly comprising:
- a mounting end rotatably coupled to the carriage such that the swing arm assembly is movable between an inner position and an outer position;
- a working end having a removable debarking tool configured to remove bark from the log as the carriage rotates;
- a main body extending between the mounting end and the working end, the main body including an insert receiving recess positioned between the removable debarking tool and the mounting end;
- and
- an insert positioned in the insert receiving recess and removably coupled to the main body, the insert abuts a sidewall of the insert receiving recess and protrudes outwardly from the insert receiving recess and the main body to define a leading edge spaced from the main body, the leading edge causes the swing arm assembly to move from the inner position towards the outer position when the leading edge of the insert engages an end face of the log moving along the processing line towards the insert while the carriage rotates.
A swing arm assembly for removing material from a log, the assembly comprising:
- a mounting end for rotatably coupling the swing arm assembly to a debarker;
- a debarker tool end for receiving a tool adapted for removing bark from the log;
- a main body extending between the mounting end and the debarker tool end, the main body having a receiving recess;
- and
- an insert removably coupled to the receiving recess, the insert extending longitudinally along at least a portion of the main body from a location proximate the debarker tool and extending away from a sidewall of the receiving recess outwardly past the main body to form a leading edge for contacting logs.
