BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sample warper having a new arrangement structure of a twilling bar which can reduce the tension applied to the twilling bar during a warping operation.

[0002]

2. Description of the Related Art Conventionally, as described in Japanese Patent No. 1529104, on a conveyor belt rotatably provided on the side surface of a warping drum and moving on the warping drum at a predetermined feed speed (feed amount), One yarn guide for winding the yarn, a conveyor feeding means for controlling the feeding speed (feeding amount) of the conveyor belt, a traverse means installed parallel to the longitudinal direction of the warping drum, and a warping drum. By mounting the thread drawn out from the fixed creel on the thread selection means provided at one end of the supporting base, the yarn selection means uses the previously selected pattern data to make the yarn guide described above. There is known a sample warping machine capable of performing warp warping by each of the aforementioned means while delivering a yarn.

Further, as described in Japanese Patent No. 1767706, a plurality of yarn guides are provided, and a plurality of yarns drawn from a rotary creel is wound around a conveyor belt, so-called simultaneous warping of a plurality of yarns. The configuration of the sample warper to perform is also known.

Further, the present applicant has proposed a sample warping machine which can perform both pattern warping and simultaneous warping of a plurality of yarns by providing a fixed creel and a rotating creel together (Japanese Patent Application No. 11-9175). ), And also proposed a sample warping machine which enables bobbin conversion in a rotary creel to facilitate thread exchange in simultaneous warping of a plurality of yarns and facilitates pattern warping (Japanese Patent Application No. 2000-
076720).

In these sample warping machines, FIG.
As shown in FIG. 1, the traverse bars 18a to 18a which are the traverse means.
8 g are installed parallel to each other in the longitudinal direction of the installation spaces H1 and H2 provided on the left and right side surfaces of the warping drum A. In the example of FIG. 7, four warp bars 18a to 18d are installed on the left side surface of the warping drum A, and three traverse bars 18e to 18g are installed on the right side surface thereof. It goes without saying that the number of these twilling bars installed can be changed as necessary.

At the installation positions of these traverse bars 18a to 18g, the yarn 22 wound around the warping drum A is in the space H.
It is provided so as to be located on the yarn track when passing 1 and H2, that is, on the yarn winding track 22h. The yarn group warped on the warping drum A is warped in an endless state from the beginning of warping to the end of warping. Therefore, the warp count is incremented each time the number of warp windings is finished according to the number of warp and the number of warp windings previously input as warp data. Forming a twill.

In FIG. 7, 18c and 18d are cut twills, 18c is a cut twill upper bar, and 18d is a cut twill lower bar. 18a, 18b, 18e, 18f, 18
g is a twilling bar that forms one twill.

FIG. 8 is a cross-sectional explanatory view of the tip portion of the conventional twilling bar 18. The traverse bar 18 is in the shape of a hollow pipe, and the tip end portion thereof has a tapered surface on the lower surface side, and has a tapered shape as a whole. A hook member 20 having a hook-shaped tip is attached to the tip of the hollow portion 19 of the traverse bar 18 via a spindle 21 so as to be movable back and forth in the tip direction. As the hook member 20 moves back and forth, the yarn 22 wound around the warping drum A is selectively guided above and below the traverse bar 18 to be traversed. That is, when the hook member 20 is retracted, the thread 22 is not locked to the hook member 20 and the twill bar 1 is kept as it is.
8 reaches the lower side and is guided downward. On the other hand, when the hook member 20 is moving forward, the yarn 22 is locked to the hook member 20 and is guided as it is to the upper side of the take-up bar 18.

FIG. 9 is an exaggerated view for making it easier to understand the winding shape of the yarn shown in FIG. For example, warp number 3
If warping is performed with 000 warps and the number of warp windings is 10, the warping drum A has 3000 yarns × 10 = 30000 yarns wound thereon, and each warp bar 18a to 18g The yarn of the yarn track 22a, that is, the yarn that has been traversed,
The yarns of the second yarn track 22b, that is, the yarns that are not traversed, are classified. As a result, the yarn in the first yarn track 22a and the second yarn track 22a
The ratio of the number of wound yarns of the yarn on the second yarn track 22b is 3000 for the first yarn track 22a and 27,000 for the second yarn track 22b.

In any case, the first yarn track 22a and the second yarn track 22a
The yarn of the second yarn raceway 22b applies tension to the yarn in the direction 22h shown in FIG. 7, and the difference in the amount of yarn wound between the first yarn raceway 22a and the second yarn raceway 22b is different from each other. Bar 18
Add a to 18g. As a result, the cut Ayashita bar 18d
Is the outer side of the bobbin winding track 22h, and the cut twill bar 1
8c and the cut twilling bar 18a, 18b are the bobbin winding track 2
2h is pushed inward, and the traverse bars 18e, 18f, 18g are pushed outward with respect to the bobbin winding track 22h.

Further, under the present circumstances where the warp length (the number of warp windings) can be made longer by improving the aligned winding technique recently, the force applied to each of the twilling bars 18a to 18g is increased, and the winding operation is performed. At times, it was difficult for a female worker to pull out each of the traverse bars 18a to 18g to the outside of the warping drum A. Further, the tension of the yarn causes each of the traverse bars 18a to 18g to be distorted and the position of the above-mentioned traverse hook member 20 to be displaced, resulting in a problem of a traverse mistake.

[0012]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems of the prior art. It is possible to reduce the tension applied to the twilling bar, and the twilling bar is distorted or twilled. An object of the present invention is to provide a sample warping machine equipped with a traverse mechanism capable of extremely reducing the situation where it is difficult to remove the take-up bar.

[0013]

In order to solve the above-mentioned problems, a sample warper according to the present invention is rotatably provided on a side surface of a warper drum and moves on the warper drum at a predetermined feed amount. One or a plurality of yarn guides for winding the yarn on the conveyor belt, a conveyor belt feeding means for controlling the feeding amount of the conveyor belt, and a plurality of yarn guides installed in parallel with each other in the longitudinal direction of the side surface of the warping drum. In a sample warper having a traverse bar and a creel for setting a bobbin wound with a yarn, the traverse bar is provided at a position deviating from a winding path of the yarn around the warping drum , and The toy bar
The twill lower bar is provided on the outside of the thread winding track and cut twill
The bar is provided inside the thread winding track, and the cut twill bottom bar
-Twilling bar other than the cut and twilling bar is the twill forming method.
Install the warp inside or outside of the thread winding track and
The yarn that is simply wound around the bobbin and not traversed is in line with the bobbin winding track.
It is characterized in that it can be wound in the finished state .

That is, in the case of a twilling bar having a height difference such as the cut twilling upper bar 18c and the cut twilling lower bar 18d, the twilling bar is installed in advance by removing the twilling bar from the bobbin winding track 22h. By using the traverse means of the hook type to the rotary type as the traverse means of the other traverse bar (in this case, the cut twill top bar), it is possible to guide the yarn from the high position to the low position without forcing. It is a thing.

Further, since the rotary type twilling means projects to the tip end of the twilling bar as compared to the hook type twilling means, when the twilling bar is pulled out to the winding position, the yarn is wound on the surrounding yarn. Since there is a risk of being caught, this traverse means and a drive device (not shown) can be separated from each other so that the traverse bar can be removed after removing the traverse bar from the tip of the traverse bar. is there.

Of the plurality of traverse bars, the cut under bar is placed outside the winding path of the yarn and the cut upper bar is provided.
It is preferable that they are installed inside the intended winding track and the remaining twill bars are installed inside or outside the track and in the vertical direction.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the accompanying drawings. The illustrated examples are shown as examples, and various modifications can be made without departing from the technical idea of the present invention. Needless to say.

FIG. 1 shows an example of a sample warper W used in the present invention. Sample warper W in FIG.
Is a yarn guide 6 rotatably provided on the side surface of the warping drum A and winding the yarn 22 around the warping drum A;
A plurality of units which are provided corresponding to the yarn guides 6 at one end of a base Y supporting the warping drum A, and which are rotatably projected to a yarn exchange position at the time of yarn exchange and are rotationally accommodated at a standby position at the time of yarn storage. Yarn selecting device, that is, the yarn selecting device 27, and the yarn selecting devices 27 installed corresponding to the plurality of yarn selecting devices 27.
Alternatively, a fixed creel B for erecting a plurality of bobbins N around which the same type of yarn 22 is wound is provided, and the yarn 22 is delivered between the yarn guide 6 and the yarn selection device 27 to set the yarn order. According to the procedure, the yarn is automatically replaced and the yarn is wound on the warping drum A.

As described above, in the sample warper W, the yarns 22 are accommodated in a plurality of yarn selecting devices 27, and the yarns 22 of the fixed creel B are sequentially wound on the warp drum A as required. It can be attached. A conveyor belt 17 is movably installed on the peripheral surface of the warping drum A.

FIG. 2 shows a sample warper W as another example used in the present invention. Sample warper W in FIG.
Is a plurality of (eight in the illustrated example) yarn guides 6a to 6a.
Although it has a rotary creel F for standing up h and a plurality of bobbins 126, it is different from the sample warper W of FIG. 1 in that a yarn selection device is not provided.

In any of the types of sample warper W shown in FIGS. 1 and 2, a plurality of traverse means, that is, the traverse bar 18, is provided in the longitudinal direction of the left and right side surfaces of the warper drum A.
a to 18 g are installed in parallel with each other. The basic structure and operation of the sample warper W are widely known from the above-mentioned patent publications and the like, and detailed description thereof will be omitted.

The first feature of the present invention is that the yarn 22 wound around the warping drum A as shown in FIG.
However, the installation space H provided on the left and right side surfaces of the warping drum A
That is, the traverse bars 18a to 18g are provided at positions deviated from the yarn track when passing 1 and H2, that is, the yarn winding track 22h.

Although a preferred installation example is shown in FIG. 3, there are provided four twilling bars 18a to 18d in the installation space H1 on the left side when viewed from the creel side, and the installation on the right side when viewed from the creel side. Three twill bars 18e-1 in space H2
8g is provided. The three traversing bars 18a to 18c are located inside the bobbin winding track 22h in the installation space H1 and are provided in a straight line in the vertical direction. The traverse bar 18d is provided outside the bobbin winding track 22h. The traverse bar 18d cooperates with the traverse bar 18c to take a cut twill, and the twill bars 18c and 18d are referred to as cut twill bars.

On the other hand, the three twilling bars 18e-18g are
In the installation space H2, it is located outside the bobbin winding track 22h and is provided in a straight line in the vertical direction. Note that FIG.
As shown in Fig. 3, three twilling bars 1 in the installation space H2 on the right side
It is also possible to arrange 8e to 18g inside the bobbin winding track 22h. In addition, 2 of the left setting space H1
It is also possible to increase the number of the booklet bars 18a and 18b to three, and the three booklet bars 18e to 18g in the right installation space H2.
It is also possible to reduce the number to two.

By installing the traverse bars 18a to 18g in this manner, the yarn of the second yarn track 22b, that is, the yarn 22 which is simply wound but not traversed, is wound on the yarn winding track 22h.
Since it is wound in a state that coincides with, the yarn tension hardly occurs, no matter how the winding amount of the yarn increases,
Accidents in which the twilling bars 18a to 18g are distorted do not occur, and it is not difficult to remove the twilling bars 18a to 18g. On the other hand, it is undeniable that the yarn of the first yarn track 22a, that is, the yarn 22 that has been twilled, is tensioned because it is taken off from the center of the twilling bars 18a to 18g. However, since the amount of yarn to be twilled is much smaller than the amount of yarn to be wound, even if tension is generated, the twilling bars 18a to 18g are not distorted, and the twilling bars 18a to 18a It is not so difficult to remove 18g.

Next, the second feature of the present invention is shown in FIG.
Also, as shown in FIG. 6, the shape of the tip of the traverse bars 18a to 18g remains the same, and the rotary hook mechanism guides the yarns 22 above and below the traverse bars 18a to 18g. That is what I did. 5 and 6, the traverse bar 18 is shown in a pinched manner.

In FIG. 5, a yarn selection guide device 23 is detachably attached to the tip of the traverse bar 18 by a fixing bolt 25. The yarn selection guide device 23 has a pair of circular plates 24 that are partially cut out as cutout surfaces 24a. A fan-shaped plate 26 is pivotally attached to the center of the circular plate 24. The fan-shaped surface of the fan-shaped plate 26 is a yarn receiving surface 26a.
Has become. As shown in FIG. 6, the circular plates 24, 24 are opposed to each other at a predetermined interval by a spacer 28, and a center gear shaft 32 is provided with a gear 30 in the center thereof.
A pair of fan-shaped plates 2 on the outer surface of the circular plates 24, 24.
6, 26 are slidably mounted. A rack 34 is meshed with the gear 30, and the rack 34 is moved back and forth by a driving means 36.
The fan-shaped plate 26 is configured to rotate up and down via the gear 30. That is, the drive device (cylinder) 38
By pressing, the fan-shaped plate 26 rotates to the imaginary line position in FIG. 5, and when the drive device (cylinder) 38 is retracted, the fan-shaped plate 26 returns to the solid line position in FIG. 5 by the restoring force of the spring 40.

Therefore, the yarn 22 wound around the warping drum A is actuated by the operation of the fan-shaped plate 26 and is guided by the upper and lower portions of the traverse bar 18 to be traversed. That is, when the yarn receiving surface 26a of the fan-shaped plate 26 faces upward (phantom line in FIG. 5), the yarn 22 is received by the yarn receiving surface 26a of the fan-shaped plate 26, and then the fan-shaped plate 26 rotates downward. As a result, the guide bar 18 is guided to the lower side. On the other hand, when the yarn receiving surface 26a of the fan-shaped plate 26 faces downward (solid line in FIG. 5), the yarn 22 does not contact the fan-shaped plate 26,
The circular plate 24 falls on the notch surface 24a, slides, and is guided as it is to the upper side of the take-up bar 18.

By adopting such a configuration of the tip portion of the traverse bar 18, the yarn 22 to be wound is wound around the tip of the traverse bar 18 having the same diameter from the beginning, and the yarn having the same diameter is directly retained. Since the yarn only moves on the outer peripheral surface of the yarn 18, the tension of the yarn does not gradually increase, and the twisting bar 18 is not distorted or the twilling bar 18 becomes difficult to remove.

[0030]

As described above, according to the present invention, the tension applied to the twilling bar can be significantly reduced, the twilling bar is distorted, and it is difficult to remove the twilling bar. Can be extremely reduced.
