The invention relates to a firewood handling device for firewood pieces (6), comprising a conveyor (1), including one or more rotating, endless chains (9), wherein the conveyor extends from an input end (2) to an output end (4). The conveyor chains are provide with carriers (10), which project outwards from the outer sides of the chains and extend across and on a distance from each other in relation to the longitudinal extension of the conveyor such that spaces are formed between the carriers into which firewood pieces (6) can be positioned having their longitudinal extension across the longitudinal extension of the conveyor. The carriers (10) are formed with at least two, not cut through slots or recesses (42, 43, 44) from below as well as from above which overlap each other, wherein the conveyor (1) in its output end (4) is provided with at least two inner guiding members (45) as well as with at least two outer guiding members (46). Both the inner and the outer guiding members are provided with smooth upper sliding surfaces and are mounted such that the sliding surfaces (45′) of the inner guiding members extend and have an increasing height in the conveying direction and are positioned such that they are aligned with the slots or recesses extending from below in the carriers, whereas the sliding surfaces (46′) of the outer guiding members extend and have a decreasing height in the conveying direction and are positioned such that they are aligned with the slots or recesses extending from above in the carriers, and wherein the sliding surfaces of the inner and the outer guiding members extend essentially without interruption or somewhat overlapping in relation to each other as seen in the conveying direction.

Various embodiments of the present disclosure provide a lumber handling and cutting apparatus, including an incoming material conveyor assembly, a material infeed assembly adjacent to the incoming material conveyor assembly, a cutting assembly adjacent to the material infeed assembly, a material outfeed assembly adjacent to the cutting assembly, an outgoing material conveyor assembly adjacent to the cutting assembly, and a printer assembly adjacent to the incoming material conveyor assembly and the material infeed assembly.

A device for sorting trunks (1), in particular logs, comprises a conveyor device (3), which has carriers (2), and ejectors (4), which are arranged along the conveyor device (3), for a controlled discharge from the conveyor device (3) into log magazines (5) according to signals from a superordinate controller (6). A common rotary drive (9) is connected with each set of at least two ejector pairs (8), which are drivingly connected together by means of an axle (7). The rotary drive (9) is a torque motor, the rotor (10) of which is rigidly connected directly to the axle (7) and the stator (11) of which is rotationally fixed relative to the conveyor device (3).

A rotative lumber piece charger for transferring lumber pieces. The rotative lumber piece charger comprises: a driving shaft rotating about a longitudinal axis and a transfer wheel comprising a main body mounted to the driving shaft and rotating therewith. The rotative lumber piece charger also comprises a lumber piece grasping assembly rotatably connected to the main body and rotatable with respect to the main body about a lumber rotation axis. The lumber piece grasping assembly is operative to grasp a section of a corresponding one of the lumber pieces, temporarily retain the section of the lumber piece and release the lumber piece. The rotative lumber piece charger further comprises an angular orientation control system connected to the lumber piece grasping assembly. The angular orientation control system rotates the lumber piece grasping assembly about the lumber rotation axis.

A camfeeder system that uses an eccentric disk kicker having a friction surface that contacts surface of a heavy elongated object to smoothly and simultaneously move the elongated object in a transverse direction towards a conveyor and accelerate the elongated object in a lineal direction the conveyor travels. A method of changing a direction a heavy elongated object travels from transverse to lineal using the camfeeder system.

Diverting paddles (72) on discharge chutes guide packages into multiple destination receptacles (22, R1) assigned to the package. The paddles (38, 72) can present static or driven flat outer surfaces or static or driven roller surfaces to the packages. The paddles (38, 72) block packages from entering non-assigned receptacles (22, 24, R1). The chutes may be made tillable to feed packages into receptacles (22, 24, R1) at different elevations.

Embodiments of the present disclosure provide a workpiece singulator with one or more movable stairs. A first one of the movable stairs may include an outer step member and an inner step member that is positioned between the outer step member and a second one of the movable stairs. The step members may be movable synchronously as a single stair to transport larger workpieces and asynchronously to transport smaller workpieces on the outer step member. Optionally, the workpiece singulator may further include a sensor configured to detect the size and/or position of a workpiece. In some embodiments, the workpiece singulator may be coupled with a controller configured to control the position of the outer step member independently of the position of the inner step member. In various embodiments, a workpiece singulator as disclosed herein may be operable to selectively singulate workpieces of different sizes.

A stick distributing unit and corresponding method for laying spacer sticks over a board layer is provided. The unit includes a frame defining a stick-receiving area for receiving sticks and a hold-and-release mechanism configured to dispense each stick one-by-one. The hold-and-release mechanism includes a lower holding member selectively operable to hold and release a bottommost stick, and an upper holding member selectively operable to hold and release a penultimate stick. The unit also includes a controller configured to operate the lower and upper holding members to release the bottommost stick from the stick-receiving area and knock on the penultimate stick. The unit further has a stick-laying mechanism configured to receive and lay the released bottommost stick over the board layer.

A wood-thawing installation for thawing frozen pieces of raw timber includes a thawing channel. The thawing channel has an entrance and an exit for the pieces of raw timber for the raw wood pieces to enter and exit the thawing channel. A plurality of nozzles are located on the thawing channel to introduce a thawing liquid into the thawing channel. A first section of the thawing channel and a second section of the thawing channel are located between the entrance and the exit. The exit is closer to the second section than to the first section. At least one of the nozzles is located in the first section and connected via a pumping line to a suction opening located in the second section. Further disclosed is a method for thawing frozen raw wood pieces.

Provided is a dual lumber stacker assembly having two stackers constructed to remove lumber from a conveyor and stack the lumber. The arms are moved forward and aft by associated crank drives. The arms are moved upwards and downwards by associated cam drives. Also provided is a method stacking lumber using the dual lumber stacker.
