Then, the roving bobbin 4 on the peg conveyor 5 is moved toward the bobbin seed stone device 20, and the first two
The book roving bobbin 4.4 is attached to the gripping claw 25.2 of the transfer device 21.
The movement of the peg conveyor 5 is stopped at a position opposite to the peg conveyor 5. Next, the gripping pawl 25.25 grips the upper end of the roving bobbin 4.4 and pulls it out from the pegs 5a, 5a, so that the gripping claw 25.25 grips the upper end of the roving bobbin 4.4 and pulls it out from the pegs 32.4 on the lowered lifter 27 in the lifting device 22.
32. In this case, the engagement hole 36a of the engagement piece 36 in the presser device 1ff34 fits into the engagement pin 37, and the pressing portion 35a of the leaf spring 35 is positioned outside the roving bobbin storage space on the lifter 27. , roving bobbin 4,4
can be easily inserted into the pegs 32 and 32 without contacting the pressing portions 35a, respectively. Bobbin rotation device 3
The drive motor 39 at 8 is stopped and the drive motor 39 at peg 3
2.32 and the roving bobbin 4.4 inserted therein are not rotated. - On the other hand, the bobbin hanger 16.16 supported by the transport rail 7 is moved to the lifter 27.
Next, the lifter 27 is moved up to a position opposite to the upper hook 32.32 and stopped, and the lifter 27 lifts the upper end of the roving bobbin 4.4 to the bobbin hanger 16.16 of the bobbin carriage 11. Insert into. In the above case, when the lifter 27 is slightly raised from the lowered position, the engagement piece 36
The engagement hole 36a disengages from the engagement pin 37, and as a result, the pressing portion 35a of the leaf spring 35 moves inward due to the elastic restoring force of the leaf spring 35 itself, and the pressing portion 35a engages the peg 32.
．． The roving bobbin 4° 4 on the roving bobbin 32 is pressed against the outer peripheral surface of the roving winding portions 4a, 4a. Further, when the lifter 27 is slightly raised from the lowered position, the dog is disengaged from the lower limit switch, and the drive motor 39 of the bobbin rotating device 38 is rotationally driven by the signal from the limit switch. The drive shaft 39a is rotated in the direction of the arrow by this rotational drive of the drive motor 39, and the pegs 32.32 and their begs 32.32 are rotated.
The roving bobbin 4.4 inserted into the roving thread is rotated in the roving winding direction. In this case, since the pressing portion 35a of the leaf spring 35 is in pressure contact with the outer peripheral surface of the roving winding portion 4a of the roving bobbin 4 as described above, the roving end is brought into contact with the roving winding portion 4a by the rotation of the roving bobbin 4. Press down to ensure secure attachment. The rotational drive of the drive motor 39 is stopped by a signal from the upper limit switch when the lifter 27 is raised to the raised position and the dog operates the upper limit switch.

7 inserts the roving bobbin 4.4 into the bobbin hanger 16.16 and then descends again, and the transfer device 21 transfers the next two roving bobbins 4.4 from the peg conveyor 5 to the lifter 27. When it is transferred to , it rises again. When the lifter 27 inserts the roving bobbins 4, 4 into the bobbin hanger 16.16 and descends, this is detected by an appropriate detection means, and the brake motor 54 with a reducer of the intermittent feed device 49 is moved to the drive shaft 52.

57 rotates to advance one cross slider 59 and move the other cross slider 59 backward, and when these cross sliders 59.59 are moved to the front and rear ends, respectively, the limit switches 61.61 are activated. Then, the brake motor 34 with reduction gear is stopped. When one cross slider 59 is moved forward as described above, the locking arm 62 on the cross slider 59 locks the index pin 17 of the bobbin carriage 11 and moves the bobbin carriage 11 to the bobbin hanger 16. It is moved in the transport direction by twice the mounting pitch P of. The locking arm 62 is the limit switch 6

なくすことができる。As mentioned above, the bobbin carriage 11 has a mounting pitch P of 2
When the roving bobbins 1, 1 inserted into the bobbin hanger 16.16 are moved by the same amount, the roving bobbins 1, 1 are also moved in a suspended state. The intermittent movement of the bobbin carriage 11 is carried out by the bobbin hanger 1.
6.16 is performed every time the roving bobbin 4.4 is inserted,
When the required number of roving bobbins 4 are inserted into the bobbin hanger 16 of the bobbin carriage 11, the bobbin carriage 11 is transferred to the spinning frame 2 position by the continuous feeding device 100. In this case, vibrations, air currents in the factory, etc. act on the roving bobbin 4 suspended from the bobbin hanger 16, and the ends of the roving tend to unravel. Since the yarn ends are held down by the roving winding section 4a, the unwinding of the roving ends is prevented, and as a result, unwinding of the roving ends causes yarn breakage in the spinning machine, insufficient roving length, fiber scattering, etc. This problem can be eliminated.

に付着される。Also, in the frame 71, Rover 4! &le's roving bobbin 4e is doffed and the peg 74 of the peg bar 72 is in the lowering state.
The empty bobbin 4e' inserted into the peg 75 of the peg bar 73 in the downward position is removed and the roving frame 1e
A transfer device 21e is attached for inserting and attaching. Each peg 74 of the peg bar 72 is rotatably provided in the same manner as in the example shown in FIGS. 1 and 2, and only when the peg bar 72 is raised is a drive motor (not shown) of a bobbin rotating device used to rotate the roving bobbin. 4e so as to be rotated in the roving winding direction. Further, the base of a presser member 76 is pivotally supported on the peg bar 72, and the presser member 76 is urged toward the peg axis by a spring 78 so as to come into contact with a stopper 77. This holding member 7G is tilted in the direction opposite to the peg axis by a solenoid 79 or a cam only when the peg bar 72 is in the downward and upward states.
The pressing portion 76a is moved out of the roving bobbin storage space on the peg bar 72. Therefore, when the roving bobbin 4e is inserted into the peg 74 of the peg bar 72 in the downwardly yielding state and the peg bar 72 is raised, the presser member 7
The pressing portion 76a of No. 6 comes into pressure contact with the outer periphery of the roving winding portion 4ae of the roving bobbin 4e, and the roving bobbin 4e is rotated in the roving winding direction, so that the roving end is securely attached to the roving winding portion 4ae. Ru.

Pulleys (not shown) are pivotally supported at both ends, and an endless belt 81 is suspended around these pulleys and rotated in one direction by a motor or the like. A large number of legs 82 are rotatably mounted on the belt 81. A bobbin rotating device 38f is attached to one end of the frame 80 for rotating the roving bobbin 4f, which is inserted into the peg 82 and transferred, in the roving winding direction. This bobbin rotating device 38f has a pair of rotary belts 83.84 rotatably disposed on both sides of the transfer path of the peg 82, and a drive for rotating the rotary belts 83.84 in the same direction. One-turn belts 83, 84 constituted by motors 85, 86 sandwich the lower part of the roving bobbin 4f on the peg 82 and rotate it in the roving winding direction.

部４ａｆ外周面に付着される。Reference numeral 87 designates a leaf spring constituting the presser device 34f, whose negative end is fixed to the frame 80, and the pressing portion 87a at the other end is positioned within the locus of movement of the roving bobbin 4f on the peg 82. After inserting the roving bobbin 4f doffed from the roving machine into each peg 82, the belt 81 is rotated to transfer the roving bobbin 4f. The roving bobbin 4 is pressed against the suppressing portion 87a.
The lower part of f is pinched by rotating belts 83 and 84 and rotated in the roving winding direction, and as a result, the roving ends are attached to the outer peripheral surface of roving winding section 4af.

Since the roving bobbin is rotated in the roving winding direction by the bobbin rotating device in this state, it is possible to reliably press the roving end of the roving bobbin doffed from the roving machine against the roving winding section. This can prevent the roving ends from unwinding during the transfer of the roving bobbin or in the subsequent process, and can prevent troubles associated with unwinding of the roving ends. Moreover, since the roving end is unraveled when the roving bobbin is transferred by the conveyor, the roving end can be unraveled using the time during which the roving bobbin is transferred.
