  • Patent number: 11970009
    Abstract: Disclosed are high stability ink delivery system systems and methods for their use, in which a secondary reservoir is placed upstream of a printhead. The secondary reservoir can be opened to the atmosphere through a valve, such as based on the reading of a pressure sensor placed at a point before the printhead. The purpose of this valve is to open the secondary reservoir to the atmosphere when the pressure sensor indicates that the secondary reservoir can be open while avoiding air aspiration, and closing it when this condition is not satisfied.

  • Patent number: 11939995
    Abstract: Disclosed here is a system and method to control multiple eversion-based actuators using a single motor, or no motor, thereby reducing the size and cost of the multiple eversion-based actuators. An activation mechanism can include a motor rotating in an expansion direction, rotating shaft, clutch, brake, pressure source under high pressure, and/or valve. The activation mechanism can cause the actuators including a wound reel of material to unwind and lengthen. A retraction mechanism can include a motor rotating in a contraction direction opposite the expansion direction, rotating shaft, clutch, pressure source having low pressure, valve associated with the pressure source, and/or the passive retraction system. The retraction mechanism can cause the actuators to rewind and shorten.

  • Publication number: 20230339242
    Abstract: A printing system having a vacuum transfer belt conveyor includes a fixed or movable perforated platen that supports workpieces, e.g., substrates, boards or other parts, to be printed. The printing system is configured to apply vacuum action through apertures or perforations defined through the perforated platen. In an embodiment, the print system is configured to mitigate deflection of ink drops, through the implementation of both a passive system, which reduces air flow in the region below the a print bar that includes one or more printheads, as well as an active system, which distributes the workpieces, e.g., substrates or boards, with respect to perforations in the transfer belt. In some embodiments, the perforated platen is comprised of a plurality of modular plates.

  • Publication number: 20230271418
    Abstract: A printing platform includes a printing engine with one or more printheads arranged such that the ink drops are jetted vertically upwards against the action of gravity; and a substrate transportation system where the normal to the surface in contact with the substrate is parallel and with opposite direction to the travelling direction of the jetted ink drops. It is necessary to counteract the weight of the substrate during the printing process to avoid it from falling under the action of gravity. This is achieved through any of a mechanical element that interferes with the falling of the substrate and that keeps it in place; or a system that generates adhesion forces between the element that transmits the motion to the substrate, typically a conveyor belt, and the substrate through the action of electrostatic forces, an air pressure differential between both faces of the substrate, or any other suitable mechanism.

  • Publication number: 20230145295
    Abstract: Apparatus, methods, and systems for a vacuum conveyor for inkjet printing with adjustment to the covered area are disclosed. In some embodiments, a controller of a vacuum conveyor expands first one or more actuators of multiple first actuators of a substrate transportation system to decrease a suction width of an area of suction provided by the vacuum conveyor in accordance with a substrate width of a substrate being inkjet printed using the vacuum conveyor. A second one or more actuators of the multiple first actuators being retracted. The controller retracts multiple second actuators of the vacuum conveyor to increase the suction length of the area of suction while the substrate transportation system moves the substrate along the vacuum conveyor for inkjet printing of the substrate. The controller expands the retracted actuators of the multiple first actuators to increase the suction length as the substrates exit the vacuum conveyor.

  • Publication number: 20220348028
    Abstract: A printing system includes a driving belt configured to drive media through the printing system relative to one or more print heads and a vacuum conveyor system. The vacuum conveyor system includes a vacuum chamber cover having a first surface and a second surface opposite the first surface, as well as a plurality of slots through the cover that form openings from the first surface to the second surface. A seal, disposed within and extending along at least a portion of a length of a respective slot, is drivable to open or close the respective slot. A vacuum chamber below the second surface of the vacuum chamber cover is configured to apply a vacuum to the media through the plurality of slots. The applied vacuum constrains the media on the driving belt by flattening it against the driving belt.
