Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention has a warping drum, a plurality of yarn guides movable around the peripheral surface of the warping drum, and a yarn feeding station. The present invention relates to a pattern warp partial warper in which a creel is arranged and a plurality of bobbins are arranged in the rotary creel. Further, the present invention relates to a method for manufacturing a handle warp yarn by simultaneously drawing a plurality of yarns from one rotary creel and supplying the yarns to the peripheral surface of the warp drum.

[0002]

2. Description of the Related Art The basic warp thread warping machine of this type and a method for producing such a pattern warp thread are already known (see Patent Document 1).

[0003]

A1 publication.

Since this known device merely uses a rotary creel capable of receiving a limited number of bobbins, another bobbin magazine is arranged beside the rotary creel, and another bobbin magazine is provided. Store the bobbin in its bobbin magazine. Then, when a bobbin provided with a thread that does not exist in the rotary creel is required for the pattern warp, the bobbin provided with the required thread is taken out from the bobbin magazine and set in an empty mounting portion of the rotary creel. To do. At that time, when there is no empty mounting site, the bobbin that is not necessary must be removed from the rotary creel in advance.

With such a pattern warp partial warp machine,
It is certainly possible to produce handle warp yarns with more yarn than can be produced with bobbin yarns set on a rotary creel.

[0006]

However, it takes a relatively long time to replenish the rotary creel with the necessary bobbins from the bobbin magazine. At that time, the warping work must be interrupted. Furthermore, the required bobbin must be taken out of the bobbin magazine and mounted on the rotary creel. After that, the warping work will be continued. And, in order to secure the space for the new bobbin, which is required as described above, in the case where the bobbin already mounted has to be removed, the bobbin mounting work of the rotary creel is more troublesome. Will be things.

The present invention is directed to a partial warp machine and method for a pattern warp, which expands the possibilities of manufacturing a pattern warp.

[0008]

In a partial warper for a pattern warp of the type mentioned at the outset, at least one second rotary creel is arranged in the yarn feeding station, A plurality of bobbins are arranged in the creel, and a yarn from any one of the first rotary creel and at least one second rotary creel yarn from the rotary creel is supplied to the yarn guide. This can be solved by a pattern warp partial warping machine provided with means.

With the above-structured partial warp machine for warp yarns, the warp yarns for handle can first be warped using the first rotary creel. If the handle produced in the handle warp yarn requires the use of another yarn, one of the second rotary creel or a plurality of other second rotary creels.
You can simply switch to one and continue the warping process (warping work). The selection means then feed the desired thread from the "necessary" rotary creel to the thread guide each time.

Switching from one rotary creel to the other rotary creel is a relatively quick operation. In other words, the selecting means takes out the yarn of the first rotary creel from the warp region and instead pulls the yarn of the second rotary creel into the warp region. Such work can usually be accomplished within one revolution of the yarn guide or at most two revolutions. The interruption time required to draw the other required yarns into the handle warp yarn is much shorter than in conventional partial warping machines. This is particularly effective when it is desired to use a plurality of additional or different yarns for warping, instead of just one. In that case, the advantage becomes particularly remarkable as compared with the known partial warp machine for handle warp. In order to carry out a new warp on the warp drum, it can be carried out in a single transition and, as in the known art (prior art), "at the time required to replace one bobbin each" A long time such as "total time obtained by multiplying the required number of threads" is not required for new yarn feeding.

Preferably, of the first and second rotary creels, the rotary creel in which the loaded yarn cooperates with the yarn guide is aligned with the warping drum. A displacement device is provided. According to this structure, the rotary creel "in operation (state contributing to warping)", that is, the rotary creel in which the yarn cooperates with the yarn guide (the first or second rotation). The type of creel) allows it to rotate on substantially the same axis of rotation as the thread guide. This contributes to the problem of the yarn tension by suppressing the yarn tension to a small value. In this case, all the yarns are pulled out with substantially the same yarn tension regardless of the position where the yarns are arranged. Therefore, the risk that the uneven warp yarn is warped is relatively small.

[0012] Preferably, the selecting means is configured to have a number of thread holding positions corresponding to the total number of bobbins. That is, the individual yarns can be held firmly in the selection means, allowing the individual yarns to be captured or released under control. It is also possible to mount a different number of bobbins on each rotary creel. The only requirement is that the number of thread holding positions match the number of threads to be firmly held.

Preferably, one rotating creel (first
Alternatively, the yarn holding position assigned to the rotary creel of the second rotary creel) is assigned to the other rotary creel (the remaining rotary creel of the first or second rotary creel). It is configured to be closed with respect to the yarn holding position. That is, the individual yarn holding positions are grouped into a group (group), the first group (first group) is assigned to any one of the first or second rotary creel, and the other groups are grouped. (Other groups) are assigned to the remaining rotary creels of the first or second rotary creels. If each group (each group) is designed to be closed from each other, the yarn will not be entangled. The release of a thread holding position for a group of one rotary creel is only possible if the thread holding positions of all the other rotary creel threads are ensured to hold the thread firmly. It will be possible. Unless such a situation is ensured, the yarn of the one rotary creel is not released. Since this is a relatively simple logical operation,
Closing can be done by simple means, i.e. a plurality of OR elements and at least one AND element.

Preferably, the yarn guides have different yarn discharge trajectories in the axial direction, and the selecting means has a controller for assigning a predetermined yarn discharge trajectories to the individual yarns of one rotary creel. Is. According to this structure, the yarn guide that simultaneously feeds a plurality of yarns to the circumferential surface of the warp drum can feed the yarns side by side in the axial direction of the warp drum. Therefore, it is possible to consider that the yarn guide has the various yarn discharge trajectories described above. These yarn discharge trajectories are, for example, eye holes (guide holes) provided at the tip of the yarn guide through which the individual yarns run.
Can be realized by Depending on the eyelet, the relative position of one yarn in the axial direction on the warp drum with respect to the other yarns of one warp band is determined by the selection of the yarn guide. For example, when warping a black thread, a red thread, a green thread, and a white thread as warp bands in this order, the position of each thread in the circumferential direction of the thread guide, that is, the black thread is the first thread guide,
The red thread is the second thread guide, the green thread is the third thread guide, and the white thread is the fourth thread guide.
It can be realized by being assigned to the thread guide. When the arrangement order of the warp bands is different, that is, when the green, red, black, and white yarn parts are in the pattern warp band, the green yarn is the first yarn guide, the red yarn is the second yarn guide, The third yarn guide is assigned to the black yarn and the fourth yarn guide is assigned to the white yarn, and the individual yarns are fed to the peripheral surface of the warping drum in a desired order. This can be easily realized by the control device. The control device can also be arranged so that the yarn ejection trajectories of the individual yarn guides are adjusted, if necessary. However, this makes the device expensive.

The second problem is that, in the method of the kind pointed out at the beginning, at least one second rotary creel having a plurality of threads is further provided, and the first and second methods are provided.
This is solved by a method in which the rotary creel of No. 1 is alternately used as the yarn feeder, and the yarn of the rotary creel that is not actually involved in the yarn feeder is held at the standby position.

As described above in connection with the pattern warp partial warping machine, the above method allows easy incorporation (arrangement) of auxiliary yarns or yarns into the handle of the pattern warp, and warping of those yarns. Incorporation into the process only requires a relatively short time. The individual threads can be removed relatively quickly from the standby position. And just like that,
The individual threads can also be quickly returned to the standby position.
The behavior of returning to the standby position itself is known and is described, for example, in EP1136602A1 mentioned at the beginning. In this known prior art, the thread drawn from the bobbin of the bobbin magazine is held in the thread box.

Preferably, the rotary creel that is then functioning as the yarn feeder during the warping operation is arranged to be aligned with the warping drum. With this structure, the functioning rotary creel has substantially the same rotation axis as the yarn guide for feeding the individual yarns to the peripheral surface of the warping drum. As a result, the yarn path from the functioning rotary creel to the yarn guide does not change during rotation of the yarn guide and the rotary creel.

Preferably, when switching from one rotating creel to another rotating creel, ie the first and second
Among the rotary creels of (1), all the yarns are fed to the standby position when switching from one of the rotary creels to another rotary creel. In other words, during the switching process (process), there is no yarn on the yarn guide. The thread guide stops only during this short time. However, once the switching process is complete, the thread guide can again pick up the thread mounted on it from the "needs" rotary creel.

Preferably, the yarns are picked up from the standby position in a predetermined order different from the order of the fed yarns. For example, when the red yarn, the green yarn, the black yarn, and the white yarn are arranged in this order in the circumferential direction of the rotary creel, when picking up these yarns by the yarn guide, they are picked up in the order of black, green, red, and white. It is possible without any problems. In that case, there will certainly be an intersection of the threads in the space between the rotary creel and the thread guide. But this is not a problem. This is because the yarn can travel (feed) from the rotary creel to the yarn guide without being entangled with each other despite the crossing of the yarns.

Preferably, the yarn from one rotating creel is arranged to be released from the waiting position only if all the yarns from the other rotating creel are held firmly in the waiting position. . That is, the first or second
Of the rotary creels, all the yarns supplied from the remaining rotary creels of the first or second rotary creels are in the standby position. Only when firmly held will it be released from the waiting position. Such a standby position can be realized mechanically by the yarn holding position. If only the thread of the first rotary creel is released at all times, the thread entanglement is prevented with high reliability.

BEST MODE FOR CARRYING OUT THE INVENTION The present invention will be described below in detail based on the preferred embodiments with reference to the drawings.

The partial warp machine 100 for the main pattern warp has a warp drum 1. A conveyor belt 2 which is movable in a direction indicated by an arrow 3 in FIG. 1 and is arranged in parallel with an axis of the warping drum 1 (also referred to as “axis” in this specification), and a dividing rod 4 parallel to the axis. 5, 6 are arranged on the peripheral surface of the warping drum 1. The dividing rods 4, 5, 6 are called lead rods or cutting rods, depending on their function.

The rotary creel 7 arranged so as to face one of the front surfaces of the warping drum 1 has a rotary body 8, and the rotary body 8 carries a large number of bobbins 9. The rotating body 8 is driven by a motor 10.

On the front surface of the warping drum 1, the yarn guide 11 is arranged at the tip of the arm 13. These arms 13 are configured to be rotatable around the axis of the warping drum 1 and in synchronization with the rotation of the rotating body 8. Synchronous movement between the rotor 8 and the thread guide 11 is preferably provided by a suitably configured drive controller.

The yarn guide 11 draws the yarn 12 from the rotary creel 7 and feeds the yarn 12 onto the conveyor belt 2, selectively above or below the dividing rods 4, 5, 6. The yarns 12 can all be of different types (colors, or the type of yarn itself, etc.), but are preferably made up of a plurality of groups each having two or more identical yarns. Since all the yarns 12 drawn out from the rotary creel 7 are fed onto the warping drum 1 substantially simultaneously when the yarn guide 11 makes one rotation,
With these yarns 12, it is possible to manufacture (warp) a pattern warp having repeats that can be realized by these yarns 12.

However, in some cases, the number of these yarns 12 supplied from the rotary creel 7 may not be sufficient. It is conceivable to increase the rotary creel 7 for the purpose of accommodating more bobbins 9 in the rotary creel 7, but there is a limit in this case. In addition, a large number of thread guides 11 must be provided depending on the number of threads to be added, so that the threads 12 can be provided before or after the dividing rods 4, 5, 6.
It becomes difficult to control the movement when the yarn is fed.

In order to realize the repeat of the pattern warp yarn (warp band) with a plurality of yarns or other yarns (single or plural yarns), beside the rotary creel 7 (first rotary creel), Another rotary creel (second rotary creel) 7'having the same structure as the rotary creel 7 is arranged. The same components of the rotary creel 7 ′ as those of the rotary creel 7 are represented by corresponding reference numerals (reference symbols) with a dash.

The two rotary creels 7, 7'are supported on one rail 14 and are movable on the rail 14 in the directions indicated by the double-headed arrow 15. A drive device (rotating creel displacement device) 16 is provided for moving both rotary creels 7, 7 ′, which drive device 16 is schematically shown. However, this drive device 16
Can also be placed inside the base 17, 17 'of the rotary creel 7, 7'. Both rotary creel 7,
The bases 17, 17 'of 7'can be mechanically coupled to one another, for example by means of a simple connecting rod 18 (see FIG. 2).

In the operating state shown in FIG. 1, the rotary creel 7 is “active (during warping)”, that is, the yarn guide 11 pulls the yarn 12 from the rotary creel 7 and places it on the conveyor belt 2. The yarn 12 is fed. In this operating state, on the other hand, the rotary creel 7'is "inactive".
(Non-warping work) ", that is, the yarn 12 'from the rotary creel 7'is a yarn box not shown in FIG. 1 (a selection means for selectively supplying the yarn to the yarn guide). 19 '
(See FIGS. 2A to 2C). The thread box 19 '(corresponding thread box (selection means) 19 is also provided for the rotary creel 7) has a number of thread holding positions corresponding to the number of bobbins 9'of the rotary creel 7'. . Each thread holding position is a thread clamp capable of securely holding the corresponding thread 12 ', and a swinging advancing / advancing device capable of carrying each thread 12' into or out of the movement trajectory of the thread guide 11. Formed by. Such yarn handling means (yarn clamp and rocking advancing / advancing device) are known per se, and a detailed description thereof will be omitted here.

That is, as long as the rotary creel 7 is "active (during warping work)", the yarn 1 of another rotary creel 7'is
2'is firmly held in the thread box 19 '. This state is shown in FIG.

When moving from one rotary creel 7 to another rotary creel 7 ', firstly, the thread 12 of the rotary creel 7 which is then "active (warping)" is in the thread box 19 It is captured within and held firmly there. This process can be completed during one rotation of the yarn guide 11. This process (process)
It is controlled by the control device 30 connected to 19 ', for example, via an electric wire not shown in detail.

As long as all the threads 12 are held firmly in the thread box 19, ie in the standby position, both rotary creels 7, 7'can be displaced in synchronization with each other. FIG. 2B shows the process of this transition.

When another rotary creel 7'is aligned with the warping drum 1, that is, the rotation axis 20 'is aligned with the yarn guide 1.
When aligned with the axis of rotation 21 of 1, the thread 12 'of this rotary creel 7'can be picked up by the thread guide 11 under the control of the control device 30. In this state, the thread 12 of the rotary creel 7 is firmly held in the thread box 19, that is, in this state, the rotary creel 7 is held.
The yarn 12 is outside the movement trajectory of the yarn guide 11.

When the individual yarns 12 'fed from the rotary creel 7'are delivered from the yarn box 19 to the yarn guide 11, the yarn guide 11 arranges the yarns 12' on the rotary creel 7 '. You do not have to take them in the same order in which you are present. As shown, the threads 12a are guided in a different order than this, ie (in plan view)
It intersects with all other threads (see Figure 2 (c)). This is possible without problems, since this crossing is maintained as it is during the continuous rotation of the yarn guide 11, which occurs synchronously with the rotation of the rotor 8'of the rotary creel 7 '.

The individual yarn guides 11 feed the yarns 12 or the yarns 12 'to different positions on the conveyor belt 2 in the axial direction, and thus, the individual yarns 12 at the time of feeding the warp drum 1 are formed. , 12 ', that is to say the handle formed by these threads, can be taken into account by this measure.

The rotary creel 7 in the standby position (FIG. 2 (c)) is provided with a new bobbin 9 at this standby position when it is found that the storage yarn in the rotary creel 7 will run out during the next warping. Is replenished. At that time, simply, the first end of the new yarn is tied or spliced to the old yarn, and after the next replacement of the rotary creel 7, 7 ', the warping process (work) is not interrupted Work can be continued.

As mentioned above, the thread 1 of the rotary creel 7
Replacing the thread 2 with the thread 12 'of the other rotary creel 7'can be done relatively quickly. It does not cause a major interruption of the warping process (work).

Instead of the two rotary creels 7, 7'illustrated, more than two rotary creels could of course be used if required. In that case, by the same method (configuration) as the above-described embodiment, any of these rotary creels can be selectively displaceable so as to be aligned with the warping drum 1.
