An apparatus for providing a constant supply of circulating textile bobbin tubes from a delivery conveyor of a textile winding machine to a return conveyor of a textile spinning machine. A reserve magazine containing textile bobbin tubes is combined with an accumulating magazine through which tubes are received from a winder and discharged for feeding to a spinning machine, with the reserve magazine discharging tubes to a transfer conveyor whenever there is an absence of supply of tubes from the accumulating magazine. An overflow collector collects tubes received from the winder in excess of the number necessary to maintain the accumulating magazine full, with the overflow of tubes being transferred manually or automatically to the reserve magazine. Discharge from the magazines is controlled by a sensor that senses the supply of tubes to the spinning machine and by sensors that sense the advance of the transfer conveyor and the presence or absence of a tube on the transfer conveyor adjacent the reserve magazine.
An apparatus for providing a constant supply of circulating textile bobbin tubes from a delivery conveyor of a textile winding machine to a return conveyor of a textile spinning machine, said apparatus comprising a transfer conveyor for transferring tubes from said delivery conveyor to said return conveyor, a tube accumulating magazine disposed adjacent said transfer conveyor for receipt and accumulation of tubes delivered thereto by said delivery conveyor, means for discharging tubes singly from said accumulating magazine onto said transfer conveyor, a tube reserve magazine disposed adjacent said transfer conveyor downstream of said accumulating conveyor for containing a reserve supply of tubes, means for discharging tubes singly from said reserve magazine onto said transfer conveyor, means for sensing the supply of tubes on said return conveyor and for rendering said accumulating magazine discharging means and said reserve magazine discharging means operable in response to a reduction in the supply of tubes on said return conveyor, means for activating operation of said accumulating magazine discharging means in timed relation to advance of said transfer conveyor when said discharging means is rendered operable, means for activating operation of said reserve magazine discharging means to feed an initial supply of tubes to said machines and conveyors, said initial activating means including a tube counter operable to de-activate said initial activating means upon counting discharge of a selected number of tubes, and means for activating operation of said reserve magazine discharging means in response to the absence of discharge of a tube onto said transfer conveyor by said accumulating magazine discharging means.
