Apparatus for transporting roving bobbins

An apparatus for transporting roving bobbins along a transportation rail arranged between a spinning process and a roving process, comprising:

• bobbin carriages, each having a plurality of bobbin hanger for suspendingly holding roving bobbins and movably supported by the transportation rail;
• a driving device for intermittently displacing the bobbin carriage;
• and
• a roving stripper arranged midway of the transportation rail for clearing off a residual roving on the roving bobbin;
• characterized in that
• a miss bobbin treatment device is provided midway of the transportation rail between the roving stripper and the roving process, for removing a miss bobbin from which the residual roving has not been completely cleared off by the roving stripper from the bobbin hanger and, instead, donning a normal empty bobbin onto the bobbin hanger;
• the miss bobbin treatment device comprising:
• a detector, arranged midway of the transportation rail between the roving stripper and the roving process, for detecting presence and absence of the residual roving on the roving bobbin after the roving bobbin has been treated by the roving stripper;
• a peg for selectively holding the miss bobbin and the normal empty bobbin;
• a bobbin lift for displacing the peg between a first position at which the roving bobbin is transferred between the bobbin hanger of the bobbin carriage and the peg and a second position at which the normal empty bobbin is donned onto the peg;
• means for withdrawing the miss bobbin held on the peg therefrom during the downward displacement of the peg;
• and
• means for feeding the normal
• empty bobbin to the peg;
• wherein the removal of the miss bobbin from the bobbin hanger is carried out by the co-operation of the peg, the bobbin lift, and the miss bobbin withdrawal means;
• the donning of the normal empty bobbin is carried out by the co-operation of the peg, the bobbin lift and the normal empty bobbin feeding means.
