A front end conveyor includes a frame having a first side and a second side, a lower deck having a plurality of sheet supports and an upper deck having a plurality of sheet guides. Upper portions of the sheet supports lie in a first plane. The plurality of sheet supports and the plurality of sheet guides define therebetween a sheet transport path for moving sheets in a sheet transport direction toward the downstream end of the front end conveyor, and the front end system includes at least one blower directed at the sheet transport path and configured to dislodge scrap material from the sheets.

An example of an apparatus to decake a 3D printed part is disclosed. The apparatus comprises a housing including at least a conduit connectable to a gas source and at least a channel connectable to a vacuum source. The conduit, when in use, is to direct a gas flow to remove un-solidified build material particles from a surface of a 3D printed part. The channel, when in use, is to direct an airflow that generally surrounds the gas flow to extract the removed un-solidified build material particles.

Clamping an axially extending workpiece along a center axis and cleaning a shaft portion and an end to clean and dry the workpiece in a short period of time. A cleaning apparatus for cleaning the workpiece, including a cleaning chamber having a first side wall and a second side wall, a cleaning station including a cleaning axis, a cleaning nozzle, a first clamping device arranged on the first side wall, a second clamping device arranged on the second side wall, and a drying station including a drying axis, a drying nozzle, a second clamping device arranged on the second side wall, and a turn table having two regions arranged in a 180 degree rotational symmetry. The turn table arranges one of the two regions is arranged in the cleaning station, and the other in the drying station.

To treat parts printed by means of 3D printing from the powder bed, they are inserted into a trough belt conveyor which transports and circulates the parts and in which the parts are acted on by a fluid jet during the transport.

According to one aspect, there is provided a method of cleaning a 3D object on a platform. The method comprises generating with a cleaning module a cleaning airflow to remove powder particles from a 3D object and an extraction airflow to extract any removed powder particles, determining a quantity of powder particles in the extraction airflow, and moving the cleaning module relative to the platform based on the determined quantity of powder particles.

The present invention relates to an automatic height adjusting manifold, and in particular to a manifold that is adjustable to be located adjacent to a workpiece. A conveyor can have an overhead structure that supports a concealer such as a canopy or removable doors. A sizing device measures the height of a workpiece. The sizing device is outside of the work areas of the machine. A height safety is provided to make sure that no workpieces taller than the measured piece enter the machine. There are liquid bays and blowoff bays within the machine. The blowoff bay has an air knife or other manifold device. A height system is provided and is adjustable to correlate with the measured height at the sizing device. A string potentiometer can be used for an air knife position feedback to the programmable logic controller (PLC).

Systems and methods for treating an object, in particular, for disinfecting and/or drying objects and/or surfaces are provided. One or more of an air delivery system, an electromagnetic emitter (e.g., a Far ultraviolet (UV) light source), and/or an air treatment device (e.g., a gaseous hydrogen-peroxide generator) may be used to condition ambient air to treat a surface or container for use (e.g., prior to filling the container, applying a surfactant, etc.). An ionizer may be employed with one or more of the emitter or air treatment device to additionally remove static from air within or provided to a treatment area.

A device for removing particulates from plant matter that includes a shelf through which the product is introduced into the device where the plant matter is moved through toward an output wherein the machine includes a lower conveyor belt, an upper conveyor belt, drive assemblies for both conveyor belts with adjustable speed wherein each conveyor belt is supported by a shelf and wherein the upper portion of each conveyor belt is moving in the direction opposing the other one resulting in the conveyor belt portions in contact with the product traveling in the same direction. An air source is provided that forces air through product as it travels between both conveyor belts through a fixed lower conduit and an upper conduit that is movable in an upward direction through a pivoting mount across the top conveyor belt that allows for displacement of the conduit from the lower conveyor belt as the product moves through the device.

A plant support tower cleaning system for cleaning a plant support tower is provided. A drive actuator propels the tower through the tower cleaning system. One or more linear or rotating first structures each have at least one projection. One or more first actuators coupled to the one or more first structures push the at least one projection of the one or more first structures against a stem side of plant material in containers in the tower as the tower is propelled through the system. A rotating second structure has at least one circumferential projection to pull plant material from a root side of the plant containers as the tower is propelled through the system. A second actuator rotates the second structure.

This technology relates to a system for clearing sensors. The system may include an air knife, a sensor cover, and a sensor motor. The sensor cover may be configured to house one or more sensors. The sensor motor may be used to rotate the sensor cover. The air knife may be configured to clear the sensor cover of debris by providing a pressurized stream of fluid against the sensor cover as the sensor motor rotates the sensor cover.
