Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for dividing a thread sheet in a sizing machine. More specifically, in the sizing step, a thread beam from a device beam is used up and a new device beam is installed. The present invention also relates to an improvement in technology for dividing and setting a thread sheet drawn from the new device beam into a gluing machine.

[0002] In this specification, "individual division" means that a yarn sheet drawn out from a tackle beam is separated from each other in a yarn sheet path between a gluing tank and a drying device, and a divided piece (for example, a comb) Split feather)
This is a separation in which one or less yarn is distributed between each separated yarn sheet.

[0003]

2. Description of the Related Art In a sizing process, a unit yarn sheet is pulled out from several different device beams, glued together, dried, and wound around a sizing beam.

[0004] In the above process, in the integrated thread sheet that is drawn out from the device beam and integrated, the yarn density from several unit beams coexists. Is very high, that is, the pitch between yarns is very small. For this reason, adjacent yarns tend to be in a state of being entangled with each other by the time the drying stage starts. If the drying is performed in such a state that such entanglement occurs, the working efficiency in the next weaving process is greatly impaired. Also, if the yarn is fluffed during the sizing process, the yarn becomes entangled, which also impairs the working efficiency in the weaving process.

[0005] For this reason, the united yarn sheet pulled out of the gluing tank is separated again into unit yarn sheets by a dividing rod to increase the pitch between the yarns and simultaneously separate the separated unit yarn sheets. Distribute and insert one by one between the divided reeds of the comb provided, or separate each unit yarn sheet with a grooved rod and simultaneously distribute and insert the separated yarns of the unit yarn sheet into each groove. The fluff binding effect is raised by splitting and gluing the thread that has been glued on multiple sides.

For example, in a system disclosed in Japanese Patent Publication No. 56-18692, individual division is performed by engaging a comb with a thread sheet after gluing.

[0007]

However, in the case of this prior art, the distribution and insertion of the yarn between the split wings of the comb or into the groove of the grooved rod are performed manually when the old and new beams are replaced. ing. For this reason, the working efficiency is very poor, and particularly in the case of high yarn density, the work becomes more complicated because the pitch between yarns is small, and a great amount of working time is required.

In addition, since this thread distribution work is performed manually by an operator while visually checking the state of the thread sheet, a distribution error is likely to occur. From these reasons, in the case of the prior art,
In the final stage of the sizing process, it is inevitable that two or more yarns are wound in a mutually entangled state.

SUMMARY OF THE INVENTION In view of the circumstances of the prior art, an object of the present invention is to simultaneously and automatically separate individual thread sheets in a sizing process, and to mutually entangle until the drying stage due to a distribution error. Is to avoid.

[0010]

SUMMARY OF THE INVENTION For this reason, the first of this application is described.
In the invention of the present invention, the yarn sheet drawn out from the device beam is passed from the gluing tank to the drying device in a state where the yarn pitch is fixed by tape or the like for each device beam, and the tip pitch is smaller than the yarn pitch. The gist of the present invention is to engage a dividing member composed of divided pieces arranged side by side in the width direction of the thread sheet and the thread sheet in the pulled-in state by relative movement with each other.

Further, in the second invention of this application, when a thread sheet drawn out from a tacking beam is passed from a gluing tank to a drying device with a thread pitch fixed for each tacking beam by a tape or the like, first, The yarn sheet on the drying device side from the tape is provided between the gluing tank and the drying device, and the crests are engaged with the dividing rods arranged side by side in the yarn sheet width direction at an arrangement smaller than the pitch between the yarns, Then, the gist is to move the yarn sheet to a drying device in that state.

In one embodiment of the present invention, a comb is used as a dividing member.

In still another embodiment of the present invention, the yarn sheet divided and positioned in the groove of the grooved rod is further divided by a comb having a division of a tip pitch smaller than that of the division of the grooved rod. Is what you do.

[0014]

The yarn is distributed one by one between the divided pieces by engaging with a divided member having a divided piece having a tip pitch smaller than the inter-thread pitch of the unit thread sheet, or by the tape going over the grooved rod. You.

[0015]

FIG. 1 shows a first embodiment of the present invention, in which a thread sheet pulled out from a tackle beam is separated by a conventional type of dividing rod, and then individually divided by engagement with a dividing member. A comb is used as the dividing member. This comb is provided with a plurality of divided wings arranged side by side in the width direction of the yarn sheet as division pieces, and the tip pitch thereof is set to be smaller than the inter-yarn pitch of the yarn sheet drawn from the device beam. .

In the figure, a thread sheet T in which unit thread sheets drawn from two device beams are integrated is immersed in a sizing tank 1 by an immersion roller 3, and a squeezing roller 5 squeezes the sizing liquid to glue. After being pulled out from the tank 1 and separated again into two groups of unit yarn sheets by engagement with a conventional type dividing rod 9, it is sent to a drying device (not shown) via a guide roller 7.

[0017] Immediately before the yarn beam of the device beam is used up, the yarn sheet is cut between the device beam and the sizing machine and replaced with a new device beam by a known method. Is set such that the pitch between the yarns is fixed with a tape or the like for each device beam. As a fixing method, the yarn sheet may be drawn out after sticking the adhesive tape over the winding width of the yarn winding surface of the new device beam, but the winding is stopped at the final stage of the warping process of winding the device beam, Adhere the adhesive tape in the width direction on the upper and lower surfaces of the thread sheet that is in tension near the comb provided in front of the winding section, and then wind the end of the thread sheet together with the tape, but make sure that the pitch between the threads is It is desirable for fixing to. In this way, the leading end of the unit yarn sheet pulled out with the yarn pitch fixed with a tape or the like and the end of the yarn sheet remaining in the gluing machine are connected. For example, if the unit yarn sheet does not change before and after replacement, the corresponding yarn at the end of the old yarn sheet and the start of the new yarn sheet are connected. Most desirably, at the connection position, the yarns are connected and fixed by the adhesive tape such that the width of the yarn sheet is substantially maintained (that is, the pitch between the yarns is maintained).

Thereafter, when the sizing machine is operated in a slow operation, the new yarn sheet advances along the same path as the old yarn sheet, and is separated into two groups of unit yarn sheets by engagement with the conventional type split rod. It is drawn out to the drying device.

If it is desired that the thread fixing tape comes to the position of the split rod during this slow operation, and if it passes a little past that position, the state is detected by the operator's visual recognition or the action of a known sensor, and the glue is detected. The attachment is stopped. In this stopped state, the comb 10 at the standby position is advanced and engaged with the thread sheet. As a result, the yarn in each unit yarn sheet is individually divided.

In this case, one comb is used, and this comb is engaged with two groups of unit yarn sheets separated by the dividing rod 9. Also, in the figure, an engagement system for linearly moving the comb is shown, but a rotation swing type may be used instead. That is, the reed wings at the standby position may be engaged with the thread sheet by rotating and swinging the comb.

FIG. 1 shows a model example in which there are two groups of unit yarn sheets (that is, two tack beams), but usually, a larger number of unit yarn sheets are integrated. Will be taken over. In the case of this model example, when the yarns constituting each unit yarn sheet are indicated by ○ and Δ, the individual division is in a state as shown in FIG. 2, for example.

That is, the tip pitch P of the divided blades 1 which are the divided pieces of the comb 10 is set to be smaller than the pitch between the yarns of the yarn sheet passed from the gluing tank to the drying device. One or less yarns of each unit yarn sheet, for example, the yarns ○ are distributed in the gap between the adjacent divided blades 11. Because of the above-mentioned pitch relationship, there is a gap where the thread ○ is not distributed, but there is no gap where more than one thread ○ is distributed.
The same applies to yarn △. There are gaps in the same gap where two yarns from different unit yarn sheets are distributed, but these are not a problem since they are already separated by the dividing rod. Further, since the yarn is squeezed between the split feathers 11 and the split rods 9, the effect of fluff binding is significantly improved.

In the embodiment shown in FIG. 1, one comb 10 is engaged with two groups of unit yarn sheets. However, as shown in FIG. 3, one comb 10 may be engaged for each unit thread sheet group.

In this case, the individual division state in each comb 10 is as shown in FIG. For example, one or more yarns are distributed in the gap between the adjacent divided blades 11 one by one. The same applies to yarn △.

In the embodiment shown in FIG. 5, a grooved rod 20 is used in place of the comb. That is, individual division is performed by engaging the grooved rod 20 with the thread sheet T pulled out from the gluing tank 1 by relative movement. As for the mode of movement, the grooved rod 2
0 may be advanced from the standby position toward the thread sheet T, or the thread sheet T may be pressed toward the grooved rod 20 by a separately provided pressing roller.

As the grooved rod 20, for example, a rod as shown in FIG. 7 is used. That is, this grooved rod 20
Is composed of ridges 21 that form divided pieces alternately arranged in the axial direction (that is, in the width direction of the yarn sheet), and grooves 22 formed between the ridges. Be distributed. The tip pitch P of the ridges 21 which are the divided pieces of the grooved rod 20 is set smaller than the pitch between the yarns of the yarn sheet passed from the gluing tank to the drying device.

In the system shown in FIGS. 1 and 5, at the timing when the thread fixing tape comes to the position of the dividing rod, the state is detected by the worker's visual recognition or the action of a known sensor as appropriate, and the gluing machine is operated. Need to stop. When a plurality of unit thread sheets are individually divided by one common dividing member, it is desirable that the fixing tapes of the unit thread sheets come to the positions of the dividing rods at the same time. However, it is difficult to adjust such a system in practice. That is, it is difficult to engage the split member with the thread sheet at an optimal timing.

Therefore, as shown in FIG. 6, first, the unit thread sheets T are respectively engaged with the grooved rods 20. At this time, each of the yarns is not properly divided into the grooves 22 at first. However, when the unit yarn sheet is moved to the drying device, the tape does not enter the groove portion 22 of the grooved rod 20, so that when the fixing tape comes to the position of the grooved rod 20, the thread fixed by the tape becomes tape. At the same time, it is once lifted from the groove 22 of the grooved rod 20. Then, when the tape passes the position of the grooved rod 20, the thread gets into the groove 22 again. When the yarns are lifted, the respective yarns are corrected and held at the pitch between the yarns on the tackle beam from which the associated yarn sheet is drawn by the tape. Since the thread gets stuck in the groove portion 22 while being kept in the corrected state, the yarn is eventually properly divided. FIG. 8 shows an example of the individually divided state.

In the embodiment shown in FIG. 9, after the yarn is distributed by the grooved rods 20 in the embodiment shown in FIG. 6, the yarn sheet T is further provided with a segment having a tip pitch greater than the pitch P of the grooved rods. The individual division is performed by engaging the comb 10. The engagement with the comb 10 is performed after the thread fixing tape has passed the position of the grooved rod 20. In the case of this embodiment, since the division is performed in two stages before and after, the individual division is more reliable, and the effect of fluff binding is remarkably improved.
Also, as in the case of FIG. 6, since the grooved rod 20 also functions as a conventional split rod, the separation of the unit yarn sheet is performed by 2 times.
If the group is sufficient, the subsequent separation by the dividing rod may be omitted.

Further, in the embodiment shown in FIG. 10, the thread sheet T is divided into three groups of unit thread sheets by using two conventional dividing rods, and the grooved rod 20 and the comb 10 are used as the dividing members. ing. That is, the grooved rod 20 is moved and engaged with the thread sheet T before the slowing operation of the gluing machine is started. As illustrated, the path of the thread sheet is disengaged from the comb 10 by this engagement. After each tape continues the slow operation for a predetermined time to add the grooved rod 20, the grooved rod 20 is released from engagement with the thread sheet and returned to the standby position. As a result, the thread sheet split by the grooved rod 20 returns to the original path, engages with the comb 10, and is split again.
Thereafter, the sizing machine enters normal operation.

The grooved rod is not limited to the one shown in FIG. In the embodiment shown in FIG. 11, one ridge 21 and one groove 22 are arranged spirally. From the viewpoint of the splitting effect alone, it is desirable that the tip of the split piece is as sharp as possible. However, it may be rounded to some extent or a short flat shape to avoid damage to the yarn.

When the grooved rod is rotated, the fluff binding effect is improved. The rotation may be any of continuous rotation, intermittent rotation, and reverse rotation.

In order to further enhance the fluff binding effect, a humidifying means for applying water vapor or water droplets to a dividing member such as a grooved rod or a comb may be provided.

[0034]

According to the present invention, the individual division is performed simultaneously for all the yarns of the yarn sheet simply by engaging the division member with the yarn sheet, and therefore, compared with the conventional manual operation. Work efficiency is greatly improved. Furthermore, since the division is not performed manually, distribution mistakes can be completely eliminated. That is, troubles in the weaving process due to the mutual entanglement of the yarns in the gluing process can be greatly reduced.
