A control system for a needle infeed device for automatically transferring needles randomly positioned on an indexing conveyor to an engagement device for subsequent conveyance to a processing location. The needle infeed device comprises one or more robots each having a gripper means for picking and placing the needles in the engagement device. The control system comprises a control device for pausing the indexing conveyor to create a dwell cycle for the infeed device, vision tracking apparatus in communication with the control device for imaging needles at one or more predetermined locations on the indexing conveyor and for determining positional and orientation data for each recognized needle during the dwell cycle, a memory device for temporarily storing the positional and orientation data received from the vision tracking device, and, a robot control device for accessing the stored positional and orientation data corresponding to the imaged needles from the memory means and for enabling one of the robots to pick up the imaged needle in accordance with its respective positional and orientation data in order to place the needle in the engagement device.

Robotic control system for a needle sorting and feeding apparatus

An automated machine for attaching a suture to a surgical needle having a suture receiving opening formed therein, and for packaging the same in a package tray comprises a first workstation including a device for sorting a plurality of needles and orienting each needle for automatic feeding to a second swaging workstation, a second workstation including a device for automatically cutting an indefinite length of suture material to a definite length and a device for automatically swaging the needle to close the suture receiving opening about a free end of the suture to secure the suture thereto and form a needle-suture assembly, a needle packaging station including a device for sequentially receiving at least one of the needle-suture assemblies in a package tray in synchronism with the second workstation, the needle packaging station having a device for automatically winding the depending suture portion of the needle-suture assembly into the package tray, a first indexing device for sequentially receiving individual oriented needles fed from the first workstation and transferring each of the needles from the first workstation to the second workstation to form the needle-suture assembly thereat, the first indexing device sequentially indexing the needle-suture assemblies from the second workstation to the needle packaging station.
