Abstract: A system for preventing debris buildup in vacuum sensor lines includes: a manifold, including a positive air pressure source and a controller; and one or more positive air pressure lines. Each positive air pressure line is in fluid communication with the manifold and can be placed in fluid communication with a vacuum sensor line. The controller is operably connected to and selectively activates the positive air pressure source to emit a positive flow of air, which can be directed into the one or more positive air pressure lines, and then into and through the associated vacuum sensor lines to evacuate debris. In some embodiments, a positive flow of air can also be directed through one or more vacuum lines of the end effector to promote the release of a parcel engaged with the end effector and/or clear the vacuum lines of debris.

Abstract: A vacuum-based end effector for selectively engaging parcels includes a base plate to which a plurality of vacuum cups are mounted and configured to be placed in fluid communication with a vacuum source. Each vacuum cup includes a bellows having a distal end connected to a lip. The vacuum-based end effector further includes a linear actuator that is mounted to the base plate and includes an extendible arm to which at least one vacuum cup is operably connected. The linear actuator can be selectively actuated to extend the extendible arm and move the lip of the vacuum cup operably connected to the extendible arm below a common plane defined by the lips of vacuum cups which maintain a fixed position relative to the base plate to individually address a target parcel. The vacuum-based end effector can be combined with a robot to provide an improved system for selectively engaging parcels.

Abstract: A vacuum cup damage detection system detects vacuum cup damage or absence in a robot singulator including a vacuum-based end effector with one or more vacuum cups. The system generally comprises a plate and a control subsystem. The plate provides a potential point of engagement for the one or more vacuum cups of the vacuum-based end effector when the robot singulator is moved to a predetermined position in which, if present, at least one of the one or more vacuum cups of the vacuum-based end effector is in contact with the plate. The control subsystem includes: one or more sensors configured to obtain readings indicative of the engagement of the one or more vacuum cups with the plate or lack thereof; and a controller configured to determine whether any one of the vacuum cups is damaged or missing based on the readings obtained by the one or more sensors.

Abstract: An end effector for engaging flexible packaging materials includes a frame, along with a first and second wheel mounted for rotation with respect to the frame. The first wheel and the second wheel are mounted to the frame relative to each other so that the outer surfaces of the two wheels are positioned opposite of each other. The first wheel and the second wheel can be driven in opposing directions to effectively define a roller intake which can be used to draw the flexible packaging materials of a target parcel between the first wheel and the second wheel. The end effector of the present invention can be combined with a robot to provide an improved system for engaging the flexible packaging materials of a parcel.

Abstract: A rejection mechanism for a conveyor system, which pushes parcels across a surface, includes a linear actuator and a paddle mounted to the linear actuator for movement between a first position and a second position. The paddle includes a bracket portion, an upright portion, and a lateral wall portion. The lateral wall portion is configured to push parcels across a surface positioned below the lateral wall portion as the paddle is moved from the first position to the second position. In some embodiments, the rejection mechanism can further include a way cover which expands and contracts with movement of the paddle. In some embodiments, the lateral wall portion can be configured to rotate about an axis of rotation defined by a hinge to transition between an engaged and a disengaged position.

Abstract: A vacuum-based end effector for engaging parcels includes a base plate, one or more vacuum cups of a first type, and one or more vacuum cups of a second type. Each vacuum cup of the vacuum-based end effector is configured to be placed in fluid communication with a vacuum source to provide the vacuum cup with a suction force which can be used to engage and grasp parcels. Each vacuum cup includes a bellows defining a pathway for a flow of air and a lip connected to the bellows. Each lip of the one or more vacuum cups of the first type comprises a foam lip, and each lip of the one or more vacuum cups of the second type comprises an elastomeric lip. The vacuum-based end effector can be combined with a robot to provide an improved system for engaging parcels.

Abstract: A dual-material vacuum cup for a vacuum-based end effector includes a bellows having a proximal end configured for connection to the end effector and a distal end. The bellows also defines a pathway for a flow of air. A lip is connected to the distal end of the bellows, the lip defining an opening in fluid communication with the pathway for the flow of air. An insert is then connected to a distal end of the lip, and the insert is in fluid communication with the opening defined by the lip. To engage parcels of various dimension and construction, the lip is composed of a first material (such as silicone rubber or another elastomeric material), while the insert is comprised of a second material (such as a foam material).
