The tip portion Se of the new sliver S1 is inserted between the 2b, and then the upper and lower rods 16 are moved downward to close the sliver clamps 12a and 12b and the tip portion Se of the new sliver S1.
To hold.

In this state, the vertical rod 11 is raised, and the lower portion of the tip end Se of the new sliver S1 gripped by the sliver gripping tool L of the vertical rod 11 is gripped by the sliver gripping tool K at the same time. . It is also possible to open the sliver clamps 12a and 12b of the sliver gripping tool L and transfer the tip end Se of the new sliver S1 from the sliver gripping tool L to the sliver gripping tool K.

Next, the sliver gripping tool K which grips the tip end Se of the new sliver S1 is moved rightward over the operation casing M in FIG. Upper clamp 39 for new sliver
Since the new sliver S1 gripped by the sliver gripping tool K moves, the new sliver upper clamp 39 and the new sliver upper clamp 39 for the new sliver are opened as shown in FIG. It passes between the lower clamps 40 and is placed on the upper clamp 41 for the old sliver. Here, the movement of the sliver gripping tool K is once stopped.

Since the upper surface of the old sliver upper clamp 41 is higher than the upper surface of the new sliver lower clamp 40, the new sliver S1 is
Will bend on the left side of the old sliver upper clamp 41 in FIG.

Although the vertical frame J connected to the sliver gripping tool K by the elastic member 20 also moves to the right, the vertical frame J is provided on the stopper 21 provided on the horizontal frame E as described above. , And further rightward movement is blocked, and only the sliver gripping tool K continues to move rightward while extending the elastic member 20. Therefore, the new sliver S1 is cut between the sliver gripping tool L and the sliver gripping tool K, and only the new sliver S is cut by the sliver gripping tool K.
1 will be gripped.

Next, as shown in FIG. 16, the new sliver upper clamp 39 is lowered to grip the new sliver S1 between the new sliver upper clamp 39 and the new sliver lower clamp 40, and then the primary sliver S1 is clamped. When the stopped sliver gripping tool K is moved rightward again in FIG. 2, the new sliver S1 is placed on the upper surface and bent for the old sliver in the same manner as the cutting of the old sliver S2 described above. The upper clamp 41 acts as a kind of obstacle,
As shown in FIG. 7, the cutting end of the new sliver S1 is cut at this portion so as to have a tip shape.

The remaining cutting ends gripped by the sliver gripping tool K move the sliver gripping tool K to the right in FIG. 2 above the gutter 36 arranged along the longitudinal direction of the spinning machine Sp, and the sliver gripping tool K is moved to the right side. By opening the grasping tool K, the unnecessary new sliver S1 is accommodated in the gutter 36.

Next, as shown in FIG. 8, the lever 2
The downward rotation of 7c causes the upper pressing member 45 to abut against the back of the upper piecing member 37 at the upper standby position, and the upper piecing member 37 is connected to the new sliver S1 and the old sliver S1 as shown in FIG. The sliver S2 is placed on the overlapping portion.

Next, as shown in FIG. 7, the rotary plate 47 is rotated forward and backward so that the upper piecing member 37 and the lower piecing member 38 reciprocate left and right with a predetermined width. By the reciprocating movement of the upper piecing member 37 and the lower piecing member 38 in the left-right direction, the overlapping portion of the new sliver S1 and the old sliver S2 is rubbed and the new sliver S1 and the old sliver S2 are joined.

As described above, the upper piecing member 37
The shaft 50 and the shaft 53 of the lower piecing member 38 are attached to the peripheral portion of the rotary plate 47 with a phase difference of 180 degrees. Since the moving directions of the piecing members 38 are opposite to each other, the position of the overlapping portion of the new sliver S1 and the old sliver S2, which are always rubbed, is kept at the same position, and the overlapping of the new sliver S1 and the old sliver S2 that are rubbed is superposed. Since the positions of the parts do not shift to the left and right in FIG. 7, unnecessary tension is not applied to the new sliver S1 and the old sliver S2. Therefore, the new sliver S1 or the old sliver S2 is cut, or the new sliver S1 and the old sliver S2 are pulled to shorten the overlapping portion of the new sliver S1 and the old sliver S2, and the sliver is cut at this part. Nor.

When the new sliver S1 and the old sliver S2 are connected, the new sliver upper clamp 39, the new sliver lower clamp 40, the old sliver upper clamp 41, and the old sliver lower clamp are operated by the operation opposite to the above-mentioned operation. 42, the upper piecing member 37 and the lower piecing member 38 are respectively rotated in the vertical direction, and the fitting plate 67 is fitted from the positioning position shown in FIG. 11 as shown in FIG. The recess 67a of the compound plate 67 is returned to the position released from the index plate 65, the limit switch 74 is released, the drive to the spinning unit is restarted, and the new sliver S1 is supplied to the spinning unit.

At the same time, the gutter member 61 is returned to the standby position shown by the dotted line in FIG. 7, and the sliver splicing device P is used.
The operating casing M is raised so as to be positioned inside the housing H, and one cycle of sliver joining is completed.

The operational effects of the above-described embodiments of the present invention will be listed below.

Since the sliver splicing device is appropriately moved above the spinning unit that requires the sliver splicing to automatically perform the sliver splicing, labor and space can be saved.

Since the sliver splicing is automatically performed, it is possible to always obtain a constant sliver splicing portion, and it is possible to appropriately adjust the state of the sliver splicing portion such as the entangled state of the sliver comrades as necessary. it can.

At the time of cutting the old and new sliver, a clamp for placing a part of the old and new sliver and lifting it upward is arranged,
After that, since the old and new sliver are configured to be cut by pulling in the lateral direction, the cutting ends of the old and new sliver become tip-shaped, and when the cutting ends of the old and new sliver are polymerized, the overlapping portion does not become thick.

Since the old sliver extending from the empty can cut for sliver splicing is automatically returned to and accommodated in the empty can, it may be entangled with the sliver hanging from the empty can to the spinning machine or the like. Trouble can be prevented, and space for such manual work is unnecessary.

Since the gutter member which prevents the old sliver and the new sliver from hanging down is arranged, troubles such as cutting of the sliver and entanglement of the sliver due to hanging down can be prevented.

Since the unnecessary cutting end of the new sliver is automatically collected, it is possible to prevent such troubles that the unnecessary cutting end adheres to the spinning machine and save labor. Can be achieved.

Since the sliver end is automatically grasped and taken out from the new can arranged behind the spinning machine, the space behind the spinning machine can be greatly reduced and the labor can be saved.

Since the overlapping portion of the end portion of the new sliver and the overlapping portion of the end portion of the old sliver are joined by rubbing between the pair of piecing members that reciprocate in mutually opposite directions, the overlapping portion of the overlapping portion can be kneaded also during rubbing operation. The position does not shift, so that unnecessary tension is not applied to the new sliver and the old sliver, and the new sliver or the old sliver is not cut.

Further, the stroke of the piecing member is half as compared with the case where only one side is moved, which enables speeding up and space saving.

[0093]

Since the present invention is constructed as described above, it has the following effects.

When the sliver is cut, a part of the sliver is bent by an obstacle member, and then the sliver is pulled laterally so that the sliver is cut off. When the cut end of the sliver is polymerized, the polymerized part does not become thick.

Since the sliver is always cut in the vicinity of the obstacle member, the cut position becomes constant, and
The sliver ends of the books can be reliably overlapped, and sliver splice mistakes are reduced.
