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 gripper L of the vertical rod 11 below the sliver gripper L is simultaneously gripped by the sliver gripper K. . It is also possible to open the sliver clamps 12a and 12b of the sliver gripper L and transfer the tip Se of the new sliver S1 from the sliver gripper L to the sliver gripper K.

Next, the sliver gripper K holding the distal end Se of the new sliver S1 is moved rightward beyond the operation case M in FIG. Upper clamp 39 for new sliver
Is kept open upward, the new sliver S1 gripped and moved by the sliver gripper K is, as shown in FIG. 15, an open upper clamp 39 for a new sliver and a new sliver S1 for a new sliver. 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 gripper K is temporarily stopped.

Here, since the upper surface of the upper clamp 41 for the old sliver is higher than the upper surface of the lower clamp 40 for the new sliver, the new sliver S1 is formed.
Will be bent on the left side of the old sliver upper clamp 41 in FIG.

Note that the vertical frame J connected to the sliver gripper K by the elastic member 20 also moves rightward, but the vertical frame J is moved to the stopper 21 provided on the horizontal frame E as described above. And the further rightward movement is prevented, and only the sliver gripper K continues to move rightward while extending the elastic member 20. Therefore, the new sliver S1 is cut between the sliver gripper L and the sliver gripper K, and only the sliver gripper K is replaced with the new sliver S.
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 When the stopped sliver gripping tool K is moved rightward again in FIG. 2, the old sliver S1 is placed on the upper surface and bent in the same manner as the cutting of the old sliver S2 described above. The upper clamp 41 acts as a kind of obstacle, and FIG.
As shown in FIG. 7, the cut end of the new sliver S1 is cut so as to have a tip shape at this portion.

The remaining cut end gripped by the sliver gripper K is moved to the right in FIG. 2 to above the gutter 36 arranged along the longitudinal direction of the spinning machine Sp. By opening the gripper K, the unnecessary new sliver S1 is stored in the gutter 36.

Next, as shown in FIG.
By downward rotation of 7c, the upper pressing member 45 abuts behind the upper piecing member 37 at the upper standby position, and the upper piecing member 37 is moved to the new sliver S1 and the old sliver S1 as shown in FIG. The sliver S2 is placed on the overlapped portion. Even after the upper piecing member 37 is placed on the overlapping portion of the new sliver S1 and the old sliver S2, the new sliver S1 is still held by the new sliver upper clamp 39 and the new sliver lower clamp 40, The old sliver S2 is held by the old sliver upper clamp 41 and the old sliver lower clamp 42.

Next, as shown in FIG. 7, the rotating plate 47 is rotated forward and backward so that the upper piecing member 37 and the lower piecing member 38 reciprocate left and right at a predetermined width. Due to the reciprocating movement of the upper piecing member 37 and the lower piecing member 38 in the left-right direction, the overlapping portion between 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 periphery of the rotating plate 47 with a phase difference of 180 degrees, so that when the rotating plate 47 is reciprocated left and right, the upper piecing member 37 and the lower Since the moving directions of the piecing members 38 are opposite to each other, the position of the overlapped portion of the new sliver S1 and the old sliver S2 that is constantly rubbed is maintained at the same position, and the overlap of the new sliver S1 and the old sliver S2 that is rubbed is constantly maintained. Since the position of the portion does not shift 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 off, or the overlap between the new sliver S1 and the old sliver S2 is shortened due to the pulling of the new sliver S1 and the old sliver S2, and the sliver is cut at this portion. Nor.

Further, during the kneading operation by the reciprocating movement of the upper piecing member 37 and the lower piecing member 38 in the left-right direction, the new sliver S1 and the old sliver S2 are moved to the upper clamp 39 for the new sliver and the lower clamp for the new sliver, respectively. The upper piecing member 37 and the lower piecing member 3 are gripped by the clamp 40, the old sliver upper clamp 41, and the old sliver lower clamp 42.
8 and new sliver S1 and old sliver S2
The twisting in the left and right directions alternately applied to the sliver is not lost, and the twisting applied facilitates the conjugation of the new sliver S1 and the old sliver S2, and the sliver splicing is performed reliably and quickly. Become.

When the new sliver S1 and the old sliver S2 are connected, the operation reverse to the above-described operation causes the upper clamp 39 for the new sliver, the lower clamp 40 for the new sliver, the upper clamp 41 for the old sliver, and the lower clamp for the old sliver to operate. 42, the upper piecing member 37 and the lower piecing member 38 are respectively rotated vertically, and the fitting plate 67 is fitted from the positioning position shown in FIG. 11 as shown in FIG. The concave portion 67a of the mating plate 67 is returned to the position where it is released from the index plate 65, the operation of the limit switch 74 is released, the drive to the spinning unit is resumed, 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.
Is moved up so as to be positioned in the housing H, and one cycle of the sliver joint is completed.

The operation and effect of the above embodiment of the present invention will be enumerated below. Since the sliver splicing device is appropriately moved above the spinning unit requiring the sliver splicing to automatically perform the sliver splicing, labor and space can be saved.

Since the sliver splicing is performed automatically, a constant sliver spliced portion can be obtained at all times, and the state of the sliver spliced portion such as the entangled state of the slivers can be adjusted as needed. it can.

When cutting the old and new slivers, a clamp for placing a part of the old and new slivers and lifting them up is arranged.
Then, since the new and old slivers are configured to be cut by being pulled in the horizontal direction, the cut ends of the new and old slivers become spike-shaped, and when the cut ends of the old and new slivers are overlapped, the overlapped portion does not become thick.

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

Since the gutter member for preventing the old sliver and the new sliver from hanging is arranged, troubles such as cutting of the sliver due to the hanging and tangling of the sliver can be prevented.

Since the unnecessary cut ends of the new sliver are automatically collected, troubles caused by such unnecessary cut ends adhering to the spinning machine can be prevented, and labor can be saved. 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 labor can be saved.

The overlapping portion at the end of the new sliver and the end of the old sliver is connected by kneading between a pair of piecing members reciprocating in opposite directions. There is no displacement, so that no unnecessary tension is applied to the new sliver and the old sliver, and neither the new sliver nor the old sliver is cut.

The new sliver and the old sliver are respectively
The upper piecing member and the lower piecing member are kneaded while being gripped by the upper clamp for the new sliver and the lower clamp for the new sliver, and the upper clamp for the old sliver and the lower clamp for the old sliver. The twist in the left-right direction is not lost, so that the imparted twist promotes the conjugation of the new sliver and the old sliver and ensures a quick and reliable sliver splice. In addition, the stroke of the piecing member may be half that in the case where only one side is moved, so that speeding up and space saving can be achieved.

[0089]

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

The new sliver and the old sliver are respectively
Since the gripping operation is performed while the piecing member is being kneaded, the twist imparted by the piecing member is not lost, and therefore, the twisting imparted promotes the conjugation of the new sliver and the old sliver. Thus, a stable seam of a certain length can be obtained reliably and quickly.

By changing the rubbing speed of the piecing member or the sliver gripping strength, the length and hardness of the seam can be adjusted as appropriate.
