In a roving bobbin exchange system applied to a ring spinning frame (1) provided with twin parallel transporting rails (4, 5) arranged at a position right above a creel portion of each side of the ring spinning frame (1), for supporting a bobbin carriage (8) provided with bobbin hangers (15) arranged in twin parallel alignment, when roving bobbins (B) held by a bobbin carriage (8) supported by one of the twin transporting rails (4, 5) , from which rovings are supplied to the respective draft units at one side of the spinning frame, reach an almost exhausted conditions, another bobbin carriage (8) holding full packaged roving bobbins (A) is introduced to the other one of the twin transporting rails (4, 5), and when the roving bobbins of the first bobbin carriage reach an almost exhausted condition, successive unit operations of exchanging rovings being supplied to the corresponding draft units are carried out between each exhausted roving bobbin (B) of the first bobbin carriage (8) and the corresponding one of the full packaged roving bobbins (A) of the second bobbin carriage (8), from one side of the alignment of the draft units to the other side thereof, and then the bobbin carriage (8) on the first transporting rail is discharged therefrom.

摘要:
An apparatus for controlling a drive of each one of spinning frames forming a group, to which a conventional roving bobbin exchange operation for exchanging almost exhausted roving bobbins of the spinning frame with full packaged roving bobbins of a bobbin carrier on a supply rail arranged at a position close to and above the corresponding spinning frame by a known automatic apparatus mounted on a carrier which is capable of displacing along a track arranged on a floor of spinning factory along an alignment of out-end frames of said spinning frames, is applied, wherein during the spinning operation, a residual roving quantity of the roving bobbins of each spinning frame is measured, while detecting a quantity of yarn wound on cops in each spinning frame, and when the above-mentioned measurement of a residual quantity of roving bobbins reaches a predetermined value, a first signal indicating this condition is issued, while the quantity of yarn wound on the cops is measured to detect a suitable condition to start the above-mentioned roving bobbin exchange operation, and when this suitable condition is detected, a second signal indicating this condition is output, then a signal calling the automatic apparatus is output based upon the logical product of these two signals, and an allowable time for the arrival of the automatic apparatus at a working position close to a particular position close to the out-end frame of a spinning frame is set, and if the automatic apparatus for exchanging roving bobbins does not arrive at the above-mentioned working position within the allowable time, the drive of the spinning frame concerned is stopped by a means for controlling the drive of spinning frames which cooperates with the measurement of a residual quantity of a roving bobbin and measurement of a quantity of yarn wound on the cops.
