  • Patent number: 11679418
    Abstract: A work cell and method for automatically separating objects disposed in 3D clusters includes dispensing the objects onto a horizontal conveying surface to form a 2D array, reforming the 2D array into a 1D stream in which the objects move in single-file in a predefined moving direction, utilizing a vision-based or other stationary sensing system to identify a selected target object in the 1D stream as the target object passes through an image capture (sensing) region, calculating trajectory data defining the target object's time-based position in the 1D stream, and then utilizing the trajectory data to control a robot arm or other object removal mechanism such that only the selected object is forcibly removed (e.g., swiped or picked-up) from the horizontal conveying surface. A continuous-loop-type conveying mechanism includes two parallel conveyor-belt-type conveying structures and associated belt-switching structures. An AI-powered vision system identifies new object shapes during preliminary learning phases.

  • Publication number: 20230092690
    Abstract: A robotic work cell uses an object separating mechanism to disperse bulk objects into a 2D arrangement on a horizontal surface and uses a vision system to generate pick-up (positional) data and rotational orientation data for each sequentially selected target object of the 2D arrangement. A pick-and-place robot mechanism uses the positional data to pick-up each target object and uses the rotational orientation data to reorientate the target object during transfer to a designated hand-off location. A carousel-type robotic end-tool disposed on a 4-axis object-processing robot mechanism rotates a gripper mechanism around a vertical axis to move the target object from the hand-off location to a designated processing location, where an associated processing device performs a desired process (e.g., label application) on the target object. In one embodiment the gripper mechanism is selectively rotatable around a horizontal axis to facilitate processing on opposing surfaces of the target object.

  • Patent number: 11542103
    Abstract: An automated food production work cell includes a robotic system that utilizes a food-grade robotic gripper to transfer individual food items. The robotic gripper is constructed using food-grade materials and includes finger structures that are linearly movably connected by linear bearings to parallel guide rods and are independently driven by a non-contact actuating system to grasp targeted food items disposed on a first work surface, to hold the targeted food items while the robotic system moves the gripper to a second work surface, and to release the targeted food items onto the second work surface. Encoding and external sensing systems facilitate fully automated food transfer processes. Optional sensor arrays are disposed on tip portions of the finger structures to provide feedback data (e.g., grasping force/pressure). Two or more pairs of independently controlled finger structures are provided to facilitate the transfer of multiple food items during each transfer process.
