An automated lumber handling system laser-scans the top profile of multiple stacks of lumber, each of which contain boards of a unique size. Based on the scanned profiles, the system determines the order in which individual boards from a chosen stack should be transferred to a saw. The saw cuts the boards to size and in proper sequence to facilitate orderly assembly of roof trusses or prefabricated walls. Some example systems lift individual boards by driving two screws, or some other piercing tool, down into the upward facing surface of the board. A track mounted cantilever, holding the screws and a laser unit, translates over the lumber stacks to retrieve and deliver individual boards and, while doing so, the laser repeatedly scans the stacked lumber profiles on-the-fly to continuously update the profiles. The open cantilever design facilitates replenishing the stacks of lumber.

For use in a reciprocating floor slat conveyor system having formed slats made of steel, a gap filler for sealing the gaps between side-by-side steel slats includes a portion that extends upwardly into the gap, and a lower portion that is connected to one of the side-by-side slats. The gap filler is installed by pushing down the gap filler into the gap between slats.

Various embodiments illustrated herein disclose an apparatus. The apparatus comprises a rotary put wall having a plurality of totes. The apparatus further comprises a vertical reciprocating conveyor (VRC) placed within the rotary put wall. The internal vertical reciprocating conveyor (VRC) comprises a plurality of chutes to receive one or more items from a robotic device. The internal vertical reciprocating conveyor (VRC) is further configured to be rotatable with respect to the rotary put wall and to convey the one or more items into one tote of the plurality of totes of the rotary put wall.

This invention belongs to a seedling separating device based on a rack and pinion drive in the field of transplanting machine in the agricultural automation facility, including a rack, a power unit, a linear drive, a number of seedling cups and a cylinder pushing device. The linear actuator is driven by the power unit to move on the frame; these seedling cups are mounted on the linear drive; the cylinder pushing device is mounted on the frame and is located behind the seedling cups and it drives the lower part of the seedling cup to open and retracts to close. The seedling device has simple structure, controllable program and high reliability. The motor drives the seedlings cups to move left and right; the cylinder pushes the cups to be opened and closed; the trust cup is straight down, the seedling attitude is better and the location of seedling can also be adjusted. The device can not only achieve the exact location in the designated seedling, but also to achieve the seedling movement of separating seedlings to two points from the mouth of the seedling cups.

A linear conveyor includes a plurality of modules constituting a conveyance path and a slider that travels along the conveyance path. The linear conveyor includes at least one relay unit disposed across adjacent modules. The modules are configured such that each of the modules has first and second module-side connection sections provided at both ends in a direction along the conveyance path, the modules being connected in a row along the conveyance path. The relay unit includes a first unit-side connection section that is connected to the second module-side connection section of one of a set of the adjacent modules, a second unit-side connection section that is connected to the first module-side connection section of the other of the set of the adjacent modules, and a first circuit that electrically connects the first and second unit-side connection sections to each other.

An ambulance cot and cot loading and unloading system for an emergency vehicle comprises a cot having a head end, a base for mounting to a deck of an emergency vehicle, a track mounted for linear movement along said base, and an arm mounted for linear movement along said track from a retracted position to an extended position. The arm is and configured to engage the cot, and wherein when the track is extended along the base and the arm is extended along the track the arm is extended from the base in an extended position and is configured for lifting the cot and providing cantilevered support to the cot while in the extended position.

In a walking floor conveyor, an arrangement of panels lined longitudinally in a side-by-side fashion are organized into at least two correlating groups of panels. At least two panels within each group. Each panel grouping is propelled and retracted in a reciprocating manner, each by a hydraulic cylinder. The panels comprising wheel receptacles underneath the panels and at least one wheel fitted within a wheel receptacle to allow for forward and backward movement along a wheel support beam. These reciprocating panels supported by a series of wheel support beams, interior support beams and side support beams. These side support beams are at their tallest in the back and shortest in the front to provide a slant allowing for a flow of cargo and liquid runoff captured within a plurality of panel drains located between the panels towards a frontally placed auger designed for the assistance of cargo discharge.

An automated lumber handling system laser-scans the top profile of multiple stacks of lumber, each of which contain boards of a unique size. Based on the scanned profiles, the system determines the order in which individual boards from a chosen stack should be transferred to a numerically controlled saw. The saw cuts the boards to proper size and in the proper sequence to facilitate orderly assembly of a roof truss or prefabricated wall. In some examples, the system lifts individual boards by driving two retractable screws, or some other piercing tool, down into the upward facing surface of the board. A track mounted cantilever, holding the screws and a laser unit, translates over the lumber stacks to retrieve and deliver individual boards and, while doing so, the laser repeatedly scans the stacked lumber profiles on-the-fly to continuously update the profiles. The open cantilever design facilitates replenishing the stacks of lumber.

This sample rack conveying apparatus is provided with a pusher unit, a linear motion guide, and a conveyance drive mechanism. The pusher unit has a base portion, a moving member, and a base-side guide. The base portion is supported by the linear motion guide so as to be movable in a first guide direction. The moving member is provided with a pusher that pushes a sample rack. The base-side guide supports the moving member such that the moving member is movable in a second guide direction that crosses the first guide direction.
