FIELD: equipment for manufacture of knitted products. ^ SUBSTANCE: apparatus for moving shuttles of knitting machine has guides designed for moving of shuttles and made in the form of rail, permanent memory connected to controlling digital computer for selecting of shuttle number depending on number of row to be knitted, and mechanical change-over mechanism providing connection to moving mechanism for moving of selected shuttle. Shuttle moving mechanism is made in the form of chain transmissions operating in parallel, each of said chain transmissions providing movement of related shuttle. Driving sprockets of chain transmissions are connected in such a manner that direct and inverse rotation inducing couplings are disposed between sprocket and rotational motion source. Changing-over of semi-couplings is enabled by means of built-in microprocessor realizing product knitting program. Rotor for semi-couplings is made from non-magnetic material and is formed as double-sided sleeve, each side of said sleeve rotating in variable magnetic field induced by respective coils. Driving sprocket of chain transmission is positioned on rotor which is rigidly connected with said sprocket. Electric magnets of semi-couplings are made immovable. Rotor cooperates with electromagnets having immovable axially aligned pins. Auxiliary sprocket is rotating between immovable electromagnet and immovable pin. Each sleeve of rotor embraces one of rotating sprockets. Each of sprockets rotates in opposite direction with respect to one another. ^ EFFECT: wider operational capabilities and enhanced reliability in operation of apparatus. ^ 3 dwg |
