Abstract

PURPOSE:To make it possible to give a tension to a thread when spliced and to prevent the generation of kindy thread effectively, by bringing kindy thread preventing members such as a plate, rod, etc. in contact with the tip section of a bobbin when a thread released from the bobbin is guided into a thread splicing apparatus. CONSTITUTION:The thread led out from the bobbin inserted in a peg 12 is led via a thread path X that passes a guide plate 6, a preclearer 22, a thread cutting apparatus 13, a tension apparatus 14, the front surface of a suction slit 15, and a winding drum 16 into a package P to be wound. During this winding- up operation, if the thread cuts, the thread is spliced by the action of the thread splicing apparatus 2, and a lever 11 is coated with the swing motion of a suction pipe 4 for supporting and guiding the end of the thread and is lowered to the operation position 11' shown by dotted line. Accordingly, the kindy thread preventing plate 8 is lowered to the position shown by dotted line under the influence of the weight 9, and its bent section abuts on the bobbin tip 21 to prevent the kindy thread from producing.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for preventing the occurrence of fraying on the yarn end guided from the bobbin side to the yarn splicing device during yarn splicing in an automatic wine goo.

In an automatic wine goo equipped with a thread splicing device, the thread ends on the package side and bobbin side are guided to the thread splicing device during thread splicing, but generally the thread ends on the bobbin side are suctioned by a suction vibrator. After being held, the thread is guided upward to the splicing device. At that time, the thread end on the bobbin side is released from the bobbin under no tension, so it is difficult to guide the thread in the case of elastic thread or thread with unstable twist. There has been a problem in that so-called "burr crabs" may occur in the threads that have been made, leading to the formation of defective seams.

In particular, if the above-mentioned crease exists in the mechanical thread splicing device that produces the Wiverse Knot S Fisherman/t, the knot will not be properly formed because the crease is free of tension, leading to knotting errors. This is extremely inconvenient for winding.

In the present invention, when the thread is released from the bobbin by a suction pipe and guided to the yarn splicing device, a tangle prevention member such as a plate or a rond is brought into contact with the tip of the bobbin, and the thread is passed between the tangle prevention member and the bobbin core tube. This is intended to prevent the occurrence of fraying by applying resistance when passing through and applying tension to the end of the yarn on the bobbin side.

Embodiment 1 of the present invention will be described below with reference to the drawings. 0 Figure 1 is a side view of the automatic wine goo (1), in which there is a yarn splicing device (2) in the center, and behind it, the end of the yarn on the package side is connected to the yarn end. Suction arm (3) leading to splicing device (2)
A suction pipe (4) for guiding the yarn iYB on the bobbin side to the yarn splicing device (2) is rotatably arranged. The opening at the tip of the suction pipe (4) has a clamp plate (5
9, which normally closes the opening, but when the suction pipe (4) turns to the chain line position in the figure, it comes into contact with the guide plate (6) and opens the opening. (20
) has a built-in lift (10) attached to the automatic wine goo (1). A lever (11) protrudes from the frame of the automatic wine goo (1) to lift the shaft (10) from the bottom, and the lever (11) is interlocked with the camshaft (20), and is located at the position indicated by the solid line and the chain line in the figure. movement between the operating positions (ii') shown (up).

FIG. 2 shows an embodiment of the driving device for the vibration prevention plate (8). A connecting rod (28) is connected to a lever (27) that swings from the tensor opener cam (25) K around a fixed shaft (26), and the lower end of the rod presses the tensor opener rod (29). (30). The lever (30) swings around the fixed shaft (31), and the pressing surface (32) presses against and separates from the end surface of the rod (29). The rod (29) is the fixed plate (36)
The tensioner (34) is slidably supported through the tensioner (34), and the tip (not shown) moves one of the pressing surfaces of the tensioner (14) shown in the first drawing. The above rod (
A pin (65) is fixed to the middle part of the pin (3

) is fixed to the shaft (38). The shaft (58) is pivotally connected to the fixed bracket of the wine goo, and a swing lever (4) is provided at the end of the shaft (38) to actuate the anti-shake member (39).
0) is fixed at one end. The anti-shake member (39) has a rod (4
2), the upper bent part (43) comes into contact with the lever (40), and the lower bent part (44)
(45) is fixed, or L-shaped play) (45) may be fixed, or a substantially U-shaped rondo (without (45)) may be used. (46) is a rod that operates the opening/closing lever of the pre-clearer (47) provided at the bottom of the cutter (13) shown in the first figure, and is operated in conjunction with the lever (40).

Therefore, when the cam (25) rotates in the direction of the arrow (48) during the yarn splicing operation, the lever (30) turns in the direction of the arrow (49) via the lever (27) and the rod (28), and the rod (29) rotates in the direction of the arrow (49). ), and the rod (29) points to the arrow (50).
slide in the direction. At this time, due to the rotation of the swinging member (67), the lever (!40) moves in the direction of the arrow (51) via the shaft (68).
Therefore, the anti-shake member (69) rotates in the direction of the shaft (41
) is set at a constant angle in the direction of arrow (52), and the angle of (45) is set at a constant angle in the direction of arrow (52).
) It comes into contact with the tip □. The bobbin tip means the core tube, and is the part without a thread layer.

In addition, the tensor opener rod C29)K
As shown in Figure 1, the tensor that is operated is composed of two pressing surfaces (14a) and (14b), one pressing surface (14b) is fixed and the other pressing surface (14a) is movable. Normally, the pressure surface (14 &
) (14b) is pressed against the pressing surface (14b).
a) Appropriate tension is applied to the thread passing between (14b).

Next, the explanation will be given according to the order of operation.

From the bobbin inserted into the peg (12), there is a guide plate (6), a brake rearer (22), and a thread cutting device (16).
The package (
The thread is wound up to P). When thread breakage occurs, the thread end on the bobbin side (YBi suction slit) (15)K is suctioned. The camshaft (20) begins to rotate in response to a thread cutting signal (not shown) and begins a thread splicing operation. First, the suction arm (3)
turns from the solid line position to the chain line position in the figure, and after sucking the package side yarn end, returns to the solid line position again and guides the yarn end to the splicing device (2). Next, the suction pipe (4
) turns from the solid line position to the chain line position in the figure, the clamp plate (5) comes into contact with the guide plate (6), and the suction pipe (
4) The tip opening opens and suction begins. At this time, the yarn cutting device (16) is activated, and the yarn end YB is cut and sucked into the suction pipe (4). Next, the suction pipe (4) begins to rotate to return to its original position. The clamp plate (5) leaves the guide plate (6) and closes the opening again to clamp the yarn end YB. At the beginning of this pivoting movement of the suction pipe (4), the lever (11) is lowered from the solid line position in the figure to the operating position (11') shown by the chain line. The lever (11)
The shaft (10) supported by the weight (9) begins to rotate counterclockwise around the pin (7) together with the anti-shake plate (8), and the anti-shake plate (8)
The bent portion comes into contact with the bobbin tip (21), resulting in the state shown by the chain line in the figure.

As the suction pipe (4) continues to rotate further, the thread end YB is released from the bobbin, but the bobbin tip (
21) and the anti-vibration plate (8), tension is applied to prevent the occurrence of protrusion. When the suction pipe (4) returns to the position indicated by the solid line in the figure, tension is applied, and the untangled yarn end YB is guided to the yarn cutting device (13), tension device (14), and then to the yarn splicing device (2), where it is guided to the package side yarn. After the ends are spliced, they are rolled up again.

In addition, the anti-shake member (s) shown in Fig. 1 and Fig. 2 (
59) action, namely Tensor Opener Rondo (29)
FIG. 6 shows a time chart of the operations of the suction pipe (4) and the like.

The line (Lj) shows the movement of the bunr rod (29) in the tensioner, the line 41 (L2) shows the movement of the suction pipe (4), and the line (L3) shows the movement of the suction arm (3). Also flA (Ll) (L2) (L3)
also shows the shape of each cam.

That is, the suction arm (3) is turned toward the package (P) at the FG, and at the GH the end of the yarn on the package side is suction-held and guided to the yarn splicing device. The suction pipe (4) turns to the bobbin side at the QD and suction-grips the bobbin-side yarn end at the DIC and guides it to the yarn splicing device. Tenser opener Rondo (29) moves in the direction of arrow (50) in Figure 2 between AB,
In the flat portion (a), the tensor is in an open state, and at the same time, the anti-shake member (39) is in contact with the bobbin tip (21) at AB.

Therefore, the contact operation of the anti-vibration member (8) <59) with the tip of the bobbin is completed at least before the suction pipe (4) suctions the yarn end on the bobbin side at the point, and the anti-vibration The return of the members (8) and (39) to their original positions (solid line position (8) in Figure 1) is performed using the tension device (14
) is timed to occur at the same time or after the start of applying tension to the thread.

FIG. 4 shows an embodiment in which the apparatus of the present invention is applied to an automatic wine gourd in which each winding unit is supplied to and discharged from the bobby (1) shown in the first figure. 151 bobbin supply conveyor (5
The bobbin (54) conveyed by the winding unit (54) is automatically transferred from the bobbin intake position of the winding unit onto the rotating disk (57) and guided by the guide plate (58) to the winding position (5).
4IlL) The inclination (θ1) of the bobbin (54) with respect to the horizontal plane is smaller than the inclination (θ2) in the case shown in the first diagram. Therefore, when releasing the thread from the bobbin (54), there is little release resistance and there is a strong tendency for rippling to occur, so the rippling prevention member (39) according to the present invention is brought into contact with the bobbin tip (21) to provide release resistance. This makes the effect even more remarkable.

The measurement results of the dust contamination rate in the wine goo with the anti-vibration device described above and in the conventional wine goo without the same device are shown below. As the yarn splicing device, a pneumatic yarn splicing device is used which performs yarn splicing by applying a jet of air to a portion where the package side yarn end and the bobbin side yarn end are aligned substantially parallel. The experiment was conducted under the same conditions except for the presence/absence. In other words, if a mechanical knotter is used as a yarn splicing device, the yarn will often not be knotted if there is fluff, as described above, and it is impossible to measure the fluff contamination rate, so a pneumatic splicing device is used. use This shows that the wine goo having the anti-tangle device of the present invention is particularly effective when it has a pneumatic splicing device. In other words, the pneumatic splicing device performs yarn splicing regardless of the presence of rips, and the rips get mixed into the seam, making it impossible to obtain a good seam.

The measurement results are as follows.

That is, in the case where there is no fray prevention device, the occurrence of fray is suppressed and a good seam can be obtained even for unspun threads with fray mixed in near the seam after 500 yarn splicings.
