Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a traveler cutting device provided in a traveler exchanger for automatically replacing a traveler fitted in a ring of a ring spinning machine.

[0002]

2. Description of the Related Art First, a ring spinning machine using a traveler will be described with reference to FIG. The ring spinning machine 101 has a twisting mechanism 102 and a drafting mechanism 103.

The draft mechanism 103 includes a back roller 10
4, upper and lower roller pairs of a middle roller 106 having an apron 105 and a front roller 107 are arranged in order from top to bottom, and an upper roller of each roller pair is supported by a cradle arm to be openable and closable, and a lower roller of each roller pair. Is driven. The large-diameter sliver S or roving thread S becomes a thread through the draft mechanism 103. This yarn is spun through a twisting mechanism 102 described below.

The twisting mechanism 102 includes a spindle shaft 11 on which a bobbin 12 is inserted and a ring rail 14 which is vertically traversable along the longitudinal direction of the bobbin 12.
And a ring 15 fixed to the ring rail 14 and a traveler 7 that is inserted into the ring 15 and can travel in the circumferential direction.
The balloon control ring 9 and the snell wire 8 are arranged from bottom to top.

The spindle shaft 11 is normally rotated at a high speed of about 10,000 to 20,000 RPM by a belt 13 common to a plurality of weights. The yarn Y is wound on the bobbin 12 via the snell wire 8, the balloon control ring 9 and the traveler 7. Bobbin 1
When 2 is turned, the traveler 7 is pulled by the hung upper yarn Y1 and lower yarn Y2, runs on the ring 15, and twists the yarn. There is a difference in rotation speed between the bobbin 12 and the traveler 7 by an amount corresponding to the length of the yarn sent from above, and the bobbin 12 is wound by this length. That is, the ring 15 and the traveler 7 are a frictional resistance body for producing a difference in the number of rotations, and at the same time, a traveling direction changing mechanism for changing the twisting action to the winding action.

The traveler 7 is a small metal fitting having a total length of 5 mm and a width of less than 1 mm, which is usually C-shaped or clamp-shaped, and is attached to the ring 15. This traveler 7 wears because it rotates on the ring 15 at a high speed of around 10,000 to 20,000 RPM. Therefore, the traveler 7 is replaced with a new one every 1-2 weeks. Normal traveler replacement is done by hand. Insert the claw metal fitting into the gap between the traveler 7 and the ring 15 by using an appropriate claw metal fitting, move the claw metal fitting in the direction to widen the gap, and remove the old traveler. I had a traveler attached. Therefore, if all the travelers of the ring spinning machine having a large number of weights are replaced, even a skilled person needs a considerable amount of time.

Therefore, it has been desired to automatically exchange travelers by a traveler exchange equipped with a traveler exchanging device such as a traveler removing device and a traveler cutting device. In order to automatically change the traveler in this way, a traveler changer has been proposed that activates the traveler removing device and the traveler cutting device after the upper thread and the lower thread hung on the traveler are crossed over the ring. There is.

A conventional example of a traveler cutting device used in this traveler exchange will be described with reference to the perspective view of FIG. A main part of the traveler mounting device 23 includes a guide bar 36 on which a large number of the travelers 7 are aligned and supported, a cutting blade 37, a lateral positioning leaf spring 38, and the like. In order to attach a new traveler to the ring of the ring spinning machine, the guide bar 36 cuts out the leading end of the traveler 7 that is aligned and supported at the tip of the guide bar, and the traveler 7 together with the lateral positioning leaf spring 38 is illustrated. The guide bar 36 is held in a predetermined posture at the tip of the guide bar 36.

Further, the structure and operation of the essential parts of the traveler cutting device will be described in detail with reference to FIGS. 7 and 8. In FIG. 7, the cutting blade 37 is attached to a holder 41 that is swingably provided on a shaft 40 of a main body 39, and the holder 41 is biased counterclockwise by a winding spring 42. A swing control pin 43 is provided on the holder 41 so as to project therefrom. The square bar 44 is slidably held by the main body 39, and the square bar 44 is urged in the shortening direction by a tension spring 45 hung between the square bar 44 and the main body 39. A guide bar 36 is supported by the square bar 44 via a bracket 46. Further, below the square rod 44, a head positioning leaf spring 47 that determines the head position of the traveler 7 that is aligned and supported, and a turn assisting leaf spring 48 that keeps the traveler 7 in a predetermined posture when the bolt 7 turns. It is attached in a cantilever manner with 49, and the side positioning leaf spring 38 and the cam plate 51 are attached with a bolt 50 (see FIG. 6) in a cantilever manner to the side of the square rod 44.

The tip 36a of the guide bar 36 has a triangular cross section and bends toward the front in the thickness direction of the drawing.
The traveler 7 cut out by the cutting plate 37 at 6a is held in the illustrated state. Then, when the main body 39 is moved to the right in the drawing so that the traveler 7 held by the flange 15a of the ring 15 is caught, the traveler 7 having a predetermined posture with the C-shaped opening facing the right in the drawing is moved to the ring 15.
Fit in.

FIG. 8 shows the state after the traveler 7 has separated the tip 36a. The guide bar 36 is in the most advanced state from the main body 39 of the alternate long and two short dashes line, and the pin 43 of the alternate long and two short dashes line cams. The cutting blade 37 hits the plate 51 and moves away from the guide bar 36 as indicated by a chain double-dashed line. Then, when the guide bar 36 is retracted by the tension spring 45, the cutting blade 37 enters between the leading traveler 7 and the second traveler as shown by the solid line. Further, when the guide bar 36 exits, the leading traveler 7
Is pushed down the leaf spring 47 to be cut out, and the sliced traveler 7 is assisted by the turn by the leaf spring 48 to reach a predetermined posture to reach the tip 36a, and the state shown in FIG. 7 is obtained. By the above operation, the cutting out of the head of the traveler 7 aligned and supported by the guide bar 36 and the fitting of the traveler are simultaneously performed.

FIG. 9 is an enlarged view showing a state where the traveler 7 is fitted in the flange 15a of the ring 15. The traveler 7 is supported in a predetermined posture by three-point support of the two apexes a and b at the tip 36a of the guide bar having a triangular cross section and the tip c of the cutting blade 37. In this predetermined posture, the upper opening 7a of the traveler is located above the guide surface 38a of the lateral positioning leaf spring 38. When the guide surface 38a slides on the flange 15a and the whole moves to the right in the drawing, the opening of the traveler 7 is opened to the flange 1.
5a, the lower end 7b of the traveler opening is the flange 15a.
While the upper end 7a of the traveler opening is stretched, the upper end 7a of the traveler opening extends obliquely downward, and when the upper end 7a of the traveler opening is released from the tip 36a of the guide bar, the flange 15a is fitted by the restoring elasticity.

[0013]

By the way, when this traveler cutting-out device is mounted on a traveler exchanging machine and the operation of automatically exchanging the traveler for a large number of ring spinning machines is performed at high speed, the two-dot chain line in FIG. Traveler 7
In some rare cases, the upper end of the traveler opening falls below the guide surface 38a (the opening is oriented obliquely downward). The upper end of this traveler opening is the flange 15a
As a result, the traveler 7 rotates clockwise and does not engage the flange 15a, resulting in a phenomenon that the traveler exchange fails, and there is a problem that the success rate of the traveler exchange is reduced.

The present invention has been made in view of the above problems of the prior art, and an object of the present invention is to provide a traveler cutting device capable of surely cutting out a traveler in a predetermined posture. Where it is.

[0015]

A traveler slicing device for achieving the above object is a traveler slicing device for slicing out the head of a traveler that is aligned and supported by the tip of a guide bar that aligns and supports a large number of travelers and holds it in a predetermined posture. Therefore, it is provided with a posture correcting means for the traveler held at the tip of the guide bar, for example, an abutting member that abuts the upper end of the traveler opening to bring the posture to a predetermined position.

A traveler cutting device for cutting out the leading end of the traveler aligned and supported by the tip of a guide bar for aligning and supporting a large number of travelers and holding the traveler in a predetermined posture. The surface pressing member to be regulated, for example, has a pressing surface formed at the tip of the cutting blade of the traveler.

[0017]

When the abutting member against the upper end of the traveler opening is displaced upward along the flange of the ring, the upper end of the opening projecting downward is pushed up to rotate the traveler and correct the posture.

Since the pressing surface formed at the tip of the cut-out plate of the traveler presses the traveler not by the point but by the surface, rotation of the traveler is suppressed and the traveler is regulated so as not to be displaced from the predetermined position.

[0019]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a diagram showing a main part of a traveler cutting device of the present invention. FIG. 1 (a) is a side view and FIG. 1 (b) is a bottom view. FIG. 2 is an operation diagram of the posture correcting means.

In FIG. 1, with respect to the guide bar 36,
In addition to the side positioning leaf spring 38, the head positioning leaf spring 47, and the turn assisting leaf spring 48 which have been conventionally provided, a new opening upper end abutting leaf spring 55 as an abutting member is provided. There is. This leaf spring 55 for abutting the upper end of the opening
Are fastened together with bolts 49 shown in FIG. 7, and are cantilevered and elastically deformable. As shown in FIG. 1, the tip of the leaf spring 55 extends to the guide bar tip 36a, and when pushed by the flange 15a, it hits the guide bar tip 36a and is held on both sides so that it is difficult to elastically deform. Further, as shown in the drawing, the tip end portion of the leaf spring 55 can be brought into contact with the opening upper end 7a of the traveler, and when the leaf spring 55 is held by both sides and the opening upper end 7a is pushed up, the traveler 7 is moved. The positional relationship is such that a predetermined posture is achieved.

The operation of the leaf spring 55 will be described with reference to FIG. Since the upper end 7a of the traveler opening is hooked by the turn assisting leaf spring 48, the traveler opening is converted from the downward attitude to the lateral attitude when the guide bar tip 36a is turned. However, if the turn and the subsequent movement are not successful, the traveler's opening is inclined downward as shown in the figure, and the traveler tries to move out of the predetermined posture. In this case, the upper end 7a of the traveler opening is regulated by the leaf spring 55, and it is prevented from being largely displaced from the predetermined posture. Even so, it is assumed that the posture deviates from the predetermined posture as illustrated.

When the traveler 7 is mounted, the leaf spring 55 is first pushed by the flange 15a and displaced in the direction of the arrow, and the upper end 7a of the traveler opening is also pushed at the same time. As a result, the traveler 7 rotates in the direction of the arrow to a predetermined posture. Be corrected. When the tip of the leaf spring 55 hits the tip 36a of the guide bar, the leaf spring 55 is supported on both sides and the predetermined posture of the traveler 7 is maintained. Then, as the guide surface 38a slides on the flange 15a, the entire body moves to the right in the drawing and the traveler 7
Is installed.

If the plate spring 55 is corrected by hitting the flange 15a of the ring when the plate spring 55 is mounted, the mechanism is simplified without requiring any special driving means for correction. In addition, the leaf spring 55 is connected to the guide surface 3
If the guide in the height direction is made possible by sliding on the flange 15a instead of 8a, the guide surface 38a of the lateral positioning leaf spring 38 becomes unnecessary.

Next, the essential parts of another traveler cutting apparatus according to the present invention will be described with reference to FIG. The figure (a) is a side view and the figure (b) is a front view. In FIG. 1, the posture of the traveler deviated from the predetermined position is corrected by the posture correcting means, but in FIG. 3, the traveler is prevented from being displaced from the predetermined position.

In FIG. 3A, the traveler 7 is supported by the vertices a and b of the triangular cross section of the guide bar tip 36a and the tip of the cutting blade 37, but the tip of the cutting blade 37 is the same as that of the traveler 7. It is different from the conventional one in that it has a pressing surface 56 that is obliquely cut along the curved surface.

The shape of the tip of the cutting blade 37 will be described in detail with reference to FIG. The blade 37 has a width that covers both the straight portion of the guide bar 36 and the tip 36a. Then, at the blade tip of the portion corresponding to the straight portion, there is a cutting blade 57 whose front side in the drawing thickness direction is obliquely cut, and the cutting blade 57 of the traveler aligned and supported by the leaf spring 47 as shown in FIG. The cutting blade 57 has a shape that is easily inserted between the first and second positions. Further, a pressing surface 56 that is obliquely cut on the depth side in the drawing thickness direction is provided at the blade tip of the portion corresponding to the guide bar tip 36a.

Therefore, when the leading traveler, which is cut out and pushed out by the cutting blade 57, turns to the guide bar tip 36a, the pressing surface 56 presses the curved surface of the traveler. While the traveler 7 is being pressed by the pressing surface 56, the traveler 7 slides sideways to reach the guide bar tip 36a and stops at the leaf spring 38. The posture of the traveler 7 is unlikely to change due to the resistance of the pressing surface 56, and the predetermined posture after the turn is maintained.

As described above, the embodiment of FIG.
By making it difficult to shift from the predetermined posture, it is possible to reduce the mistake in mounting the traveler. On the other hand, the embodiment shown in FIG. 1 corrects the posture of the traveler 7 which is deviated from the predetermined posture, thereby reducing the mistake in mounting the traveler.
Therefore, the posture regulating means by the surface pressing member and the posture correcting means by the contact member are not limited to those used separately,
If used together, the success rate of traveler exchange can be further increased.

Next, an example of the operation unit 31 equipped with the traveler exchanging device including the above-mentioned traveler cutting device will be described with reference to FIGS. 4 and 5. 4 is a front view of the operating unit 31, and FIG. 5 is a top view of the operating unit. . The operation unit 31 is supported by a carriage unit (not shown) so as to be able to move up and down, and can travel along the ring rail 14. This operation unit 31 is divided into three stations S1, S2 and S3. The station S1 has a positioning plate 26, a roller 33, and a lever 27.
And a recovery box 32 is provided at the station S2.
A roller 28, a tensor 30, a yarn pulling lever 1, a traveler removing device 17, and a traveler cutting device 22 are provided, and a roller 29 and a slack eliminating device 34 are provided at the station S3.

The traveler exchange procedure by the operation unit 31 is as follows. Loosen the thread at station S1,
At the station S2, the traveler is replaced, and at the station S3, the thread is stretched and the roles are shared. At the station S1, the roller 33 is located on the central bobbin 12, and the central bobbin 12 is reversed to loosen the yarn. Then, the operating unit 31 travels one pitch P to the left side of the drawing, and the station S2 is in the illustrated state.

At this time, the lever 27 slightly moves the traveler 7 so that the traveler 7 moves out of the place where it interferes with the operating position of the traveler removing device 17 described below. Then, the positioning plate 26 advances and is fitted into the ring 15 to be positioned. Next, the yarn Y is applied by the tensor 30.
Is stored, and the yarn Y can be fed or fed with a predetermined yarn tension. Then, the tip of the traveler removing device 17 advances onto the ring 15, the roller 28 rotates the bobbin 12 in the forward direction to run the traveler 7, and the traveler 7 is hooked on the tip of the traveler removing device 17. Next, the thread shifting lever 1 moves the thread across the ring 15, and the traveler removing device 17 removes the old traveler 7 and puts it in the collection box. After that, the traveler slicing device 22 is installed on the new traveler 7.
To the ring 15. Then, the tensor 30, the yarn pulling lever 1, the traveler removing device 17, and the traveler slicing device 22 retract, and the operating unit 31 travels one pitch P to the left side in the drawing. And the roller 29 is the bobbin 12
The slack removal device 34
Make sure the thread is completely stretched.

In the above description of the embodiment, the case where the traveler cutting device is equipped in the traveler exchanger has been described as an optimum example, but the present invention is also applied to the traveler cutting device used alone as a manual tool. it can. In this case, even if it is not an expert, the tool has a high success rate.
