Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a creel device, and more particularly to a creel device for pulling a yarn from each yarn feeder and guiding it to a warper or a sizer.

[0002]

2. Description of the Related Art Japanese Unexamined Patent Publication (Kokai) No. 2-154023 discloses a winding device for pulling yarns from a large number of yarn feeders attached to a bobbin creel all at once and winding them into a beam. It is disclosed that a yarn breakage sensor is provided in the device to stop the winding device when a yarn breakage occurs.

[0003]

By the way, it is well known that the inertial force of the winding device is large and it takes a considerable time from the occurrence of yarn breakage to the stop of the winding device. Moreover, the yarn breakage point is not specified between the yarn feeder and the warper or sizer. That is, if there is an unwinding failure portion in the yarn layer of the yarn feeder, the unwinding resistance increases, and the yarn feeder and the warper or sizer are pulled to each other, and a yarn break occurs at the weakest portion of the yarn during this time. Of. For this reason, the thread breakage may be wound up, and the winding device must be reversed to perform the repair work. In addition, it is difficult to find the cut yarn breakage because it breaks into the beam, which increases the complexity of the repair work.

The present invention has been proposed in view of the above problems of the prior art, and an object of the present invention is to provide a creel device capable of easily performing the subsequent repair work even if a yarn breakage occurs.

[0005]

In order to achieve the above object, the present invention provides, in each creel device, a storage device that positively draws a yarn from the yarn supply body and stores it.
The yarn is guided to a warper or a sizer through the storage device.

[0006]

Since the yarn from each yarn feeder is positively pulled out by the storage device, if the yarn unwinding failure occurs in the yarn feeder,
The yarn is pulled between the yarn feeder and the storage device, and yarn breakage occurs during this period. After that, the stop signal of the winding device is output, but during the inertial operation of the winding device when a yarn breakage occurs, the yarn stored in the storage device is fed out, so the cut end of the yarn on the winding device side Is not taken up by the take-up device.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows a first embodiment of the present invention in which a stationary drum type storage device is used as the storage device. A first fixed yarn guide 5 is provided on the yarn drawing side of the yarn feeder 3 attached to the bobbin creel 1. A stationary drum type storage device 7 is provided at a predetermined position on the downstream side. The yarn Y drawn out from the stationary drum type storage device 7 is the second fixed yarn guide 9
Supplied to a warper or sizer.

The basic structure of the storage device 7 is composed of a stationary drum 71 and a rotating yarn guide 72 which rotates around the stationary drum 71 in a relatively separated manner. That is, the rotary yarn guide 72 is driven by the storage motor 63 via the gear train 61.

A ring brush 77 is provided at the tip of the stationary drum 71. The ring brush 77 is used not only to create a trigger for winding the yarn Y, but also to apply a tension to the yarn Y unwound from the stationary drum 71.

A photoelectric yarn amount sensor 74, for example, is provided at a predetermined position corresponding to the yarn accumulating portion of the stationary drum 71, and detects the amount of yarn accumulated on the stationary drum 71. That is, the yarn amount sensor 74 is the yarn Y of the stationary drum.
The yarn present signal is output when the yarn Y is present at a predetermined position in the storage section. The detection signal of the yarn amount sensor 74 is output to a drive control device (not shown) for the storage motor 63 to turn on / off the storage motor 63, and a fixed amount of yarn Y is constantly wound around the stationary drum. I keep it. That is, when the storage amount of yarn Y unwinds and the yarn presence signal is no longer output, the rotary yarn guide 72 is rotated until the next yarn presence signal is output, thereby maintaining a constant storage amount. Secured.

A yarn breakage sensor 8 is provided at a predetermined position between the first fixed yarn guide 5 and the yarn inlet of the rotating yarn guide 72.
1 is provided, and the yarn feeder 3 and the rotating yarn guide 72 are provided.
When a yarn break between the two is detected, and when it is detected that the yarn is broken, a stop signal is output from a yarn break detection device (not shown) to stop the rotation of the rotary yarn guide 72 and stop the related machines. Furthermore, the rotating yarn guide 7
A yarn break sensor 83 is also provided between the yarn guide outlet and the stationary drum at a predetermined rotation angle of 2 to detect the presence / absence of yarn continuous from the outlet of the rotating yarn guide 72 to the storage portion of the stationary drum 71. That is, if the yarn breakage detection device (not shown) does not output a yarn presence signal from the yarn breakage sensor 83 when the rotary yarn guide 72 is at the predetermined rotation angle, it determines that the yarn is broken and outputs a stop signal to the related machine. To do.

Next, the operation of this embodiment will be described.
The rotating yarn guide 72 is driven by the storage motor 63, and pulls out the yarn Y from the yarn supplying body 3 to move the stationary drum 71.
The yarn Y is wound around the storage part of. And stationary drum 7
The yarn Y stored on the second fixed yarn guide 9
Is guided to and pulled out by the warper and sizer. At this time, the withdrawal tension of the yarn withdrawn from the stationary drum 7 is constant and stable regardless of the winding diameter of the yarn feeder.

By the way, if there is a defective portion in the yarn layer of the yarn feeder, the unwinding resistance from the yarn feeder increases, and the yarn feeder 3
And the rotary yarn guide 72,
Thread breakage occurs between the yarn feeder and the storage device. This yarn breakage is detected by the yarn breakage sensor 81 or 83, and a machine stop signal is output from a yarn breakage detection device (not shown). During the inertial operation until the machine stops, the stored yarn stored on the stationary drum 71 is sent to and supplied to a machine such as a warper or a sizer. In this case, the stored yarn amount needs to be set larger than the length pulled out during the inertial operation. Then, the cutting yarn end is never fed out from the stationary drum and supplied to the warper or the sizer. Moreover, since the cut ends of the warper, sizer, etc. are surely present on the stationary drum, the subsequent repair work becomes easier.

After this, that is, after the machine is stopped, the cutting end on the yarn feeder 3 side is connected to the cutting end on the stationary drum 71. Then, the post-repair storage motor 63 is driven to store a predetermined amount of yarn and then the machine is started.

A motor 63, which is a drive source of the rotating yarn guide 72, may be provided for each storage device 7, and
As shown in FIG. 2, one motor 63 may drive the rotating yarn guides 72 of a plurality of storage devices.
In the figure, reference numeral 65 is a drive shaft. Each rotating yarn guide 7
2 and the drive shaft 65 are respectively provided with electromagnetic clutches 73, and during operation, corresponding electromagnetic clutches 73 are turned on / off by a signal from a yarn amount sensor provided for each stationary drum 71. Stores a fixed amount of yarn. Further, after the repair, when the predetermined amount of the yarn is stored in the corresponding stationary drum 71, the electromagnetic clutch 73 is deactivated and the rotary yarn guide 72 is rotated by another driving device. A tension applying device such as a plate tensor is provided between the first fixed yarn guide 5 and the inlet of the rotating yarn guide 72 so that the yarn is pulled out to the storage device 7 via the tension applying device. It is preferable to set the resistance of the tension applying device to the yarn larger than the resistance of the ring brush 77 to the yarn. According to such a configuration, if the yarn has a weak portion, the yarn breakage is actively caused between the tension applying device and the rotating yarn guide 72, which is effective from the viewpoint of quality control. is there.

In the above embodiment, the storage device has been described as a stationary drum type, but the present invention is not limited to this, and it is a rotary drum type storage device 17 as shown in FIG. Is also good. That is, the yarn may be sandwiched between the rotary storage drum 171 and the nip roller 172 and stored in the storage drum 171.

[0017]

As described above, according to the present invention, yarn breakage occurs between the yarn feeder and the storage device,
During the inertial operation of the winding device or the like when a yarn breakage occurs, the yarn stored in the storage device is fed out, so that the cut end of the yarn is not supplied to the winding device or the like. Therefore, the subsequent repair work can be easily performed. Further, if the storage amount of the storage device is set to be larger than the yarn amount that is pulled out during the inertial operation of the winding device or the like, the cut end on the winding device side can be reliably placed on the storage device after the winding device is stopped. Therefore, the repair work thereafter becomes easier.
