The modular lumber stacker utilizes a single fork and board width sensor to load layers of boards with varying widths onto a lift table. The single-fork loader allows a fork lift to readily access the opposing side of the lift table to remove a multi-layer stack of boards. An adjustable unloading stop may be used to justify the stack by distributing the dead space in each layer between the boards to justify the stack to avoid jagged stack edges and improve stacking stability.

A load former includes a frame, a loading zone bounded on a first end by a stop wall having a stop surface lying in a plane and a rear wall at a rear side of the frame, and a cookie sheet slidably supported by the frame for travel along a path perpendicular to the plane. The path includes portions on first and second sides of the plane, and a portion of the cookie sheet in the second portion of the path defines a bottom of the loading zone. A platform extends over the first portion of the path, and a top wall is vertically spaced from the platform to define a storage space between the top wall and the platform. The storage space has a front opening so that it is accessible from the front of the load former.

A board stacking system for stacking board layers into a stack, and associated method are provided. The board stacking system includes a board stacking apparatus adapted to arrange board layers into the stack. The board stacking apparatus having a stack holder comprising an adjustable stacking area for supporting the stack, the stacking area having a length defined between a front edge and a back edge. The board stacking apparatus further having one or more stacking arms operable to receive board layers from a board dispensing mechanism and sequentially arrange the board layers onto the forming stack. The board stacking system further includes a scanner positioned and configured for measuring a width of the board layers and transfer the information to the stack holder to allow adjustment of the length of the stacking area to substantially correspond to the width of the previously measured board layer.

A method including filling an internal passage of an additively manufactured (AM) article with a state change fluid, causing the state change fluid to change from a first state having a first viscosity to a second state that is either solid or has a second viscosity that is higher than the first viscosity within the internal passage, causing the state change fluid to change back from the second state to the first state, removing residual powder from the additively manufactured article by flushing the state change fluid from the internal passage, measuring electrical impedance of a piezoelectric wafer connected to the additively manufactured article, and determining that more than a threshold amount of residual powder remains within the AM article based on the measured electrical impendence of the additively manufactured article being outside of a selected range from an expected impendence value.

Implementations of an automated round tube loading machine are provided. In some implementations, the automated round tube loading machine comprises a tube pickup mechanism, a tube stacking mechanism, and a tube loading mechanism. In some implementations, the automated round tube loading machine may further comprise a front side conveyor, a back side conveyor, and/or a computer system. In some implementations, a method of operation of the automated round tube loading machine comprises the machine receiving, picking up, moving, dropping off, stacking, and loading a plurality of round tubes into a box.

A method for loading a container with packages, using a device having at least one guide. At least one hand element is displaceable in the longitudinal direction of the guide, and is provided on the at least one guide. The hand element has a plurality of finger elements. The finger elements have at least two flexible flank elements extending together from one end of the finger element to the opposing end. The at least two flexible flank elements of the finger elements are flexibly connected together via a plurality of webs. The finger elements may be adjusted from at least one curved position into at least one extended position and back. The at least one hand element takes packages one after the other, and deposits the packages into the container in a stack. The hand element is displaced along the guide between the deposit of two successive packages.
