  • Publication number: 20230120642
    Abstract: An apparatus for an efficient label application comprising a conveyor belt; a barcode reader that is disposed above a conveyor belt and attached to a first cross beam; a 3D profiler that is disposed above said conveyor belt and attached to a second cross beam, and records size, shape, and orientation of a shipping package; a first plexiglass shield that comprises a light curtain; wherein said first plexiglass shield and light curtain protect a robotic arm's operating space on one side of said conveyor belt; a second plexiglass shield that protects said robotic arm's foot; a printer that is disposed next to said robotic arm; two upward facing fans that are disposed between said printer and said robotic arm, and, together, create an air cushion; a third plexiglass shield that protects said robotic arm, air cushion, and printer on second side of said conveyor belt; said first plexiglass shield, third plexiglass shied, and said conveyor belt define and protect a critical zone of said robotic arm's operating space

  • Publication number: 20190039772
    Abstract: An improved print and apply device that receives a single data stream containing label printing/encoding data and positioning data. The single data stream may comprise data relating to the skew angle of the package. The print and apply device transmits label data to a printer/encoder portion of the system and positioning data to motors that move the system. Once the printer portion and the applicator portion have indicated they are ready, a signal is sent to apply the label. Supplemental motors can adjust the package in the X, Y, and/or Z directions until the skew angle is determined to be within an acceptable approach to zero. The label can be applied anywhere in the X, Y, and/or Z directions on a package.

  • Publication number: 20180260168
    Abstract: A printer system, comprising: a print and apply device configured to print or encode a label and apply the label to a package, wherein the device has a printer/encoder portion and an applicator portion; a first motor to move the print and apply device in an X-direction; a second motor to move the print and apply device in a Y-direction; a third motor to move the print and apply device in a Z-direction; a controller coupled to the print and apply device and having a single interface configured to receive a first single data stream comprising label data from the first single data stream; and a command parser configured to receive the first single data stream and parse the label data to the printer/encoder; the controller is further configured to receive a second single data stream comprising positioning data from the second single data stream; and the command parser configured to receive the second single data stream and parse the positioning data to the applicator portion.

  • Patent number: 9628062
    Abstract: A 24-transistor D flip-flop circuit operates in a sampling mode when a clock signal has a first voltage state, and a holding mode when the clock signal has a second voltage state. The flip-flop circuit includes an internal control node coupled to a reference voltage node by way of a transistor controllable to couple the internal control node to the reference voltage node when the clock signal has the second voltage state. The flip-flop has very low power dissipation as it includes a 4-transistor change-sense component to detect changes in input data. The change-sense component is coupled in series with the transistor and receives an indication of an input voltage state of the flip-flop circuit and an indication of an output voltage state of the flip-flop circuit, and inhibits toggling of the internal control node if the indicated input voltage state and the indicated output voltage state are the same.
