Abstract

(57) [Summary] [PROBLEMS] To provide a draw false twisting machine capable of preventing yarn interference between a second feed roller and a secondary heater arranged back to back. [Structure] A second feed roller and a secondary heater provided below the second feed roller are provided back to back, and a separator is provided between the feed rollers provided back to back for the secondary heater.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a drawing false twisting machine.

[0002]

[Prior Art]

 Conventionally, a draw false twisting machine draws and false twists a heated yarn and then reheats it to stabilize the yarn, and then winds it by a winding device, which will be described below with reference to FIG.

In FIG. 2, a drawing false twisting machine 1 is provided with a false twisting device N, a setting secondary heater H2, a winding device W, etc. at the center of a drawing machine 2 back to back. A primary heater H1 for texturing and a creel stand 4 which is a yarn feeding device, etc. are arranged symmetrically on both sides of each of them via a passage 3. In FIG. 2, the left side portion in the drawing is omitted. There is.

The yarn Y supplied from a large number of bobbins B provided on the creel stand 4 is guided by the separate plate 4a, sent from the first feed roller F1 into the primary heater H1, and heated, and then ballooned. It is cooled by the control plate 5 in a state in which ballooning is prevented, is further false twisted by the false twisting device N, and is taken up by the second feed roller F2.

At this time, the drawing is performed due to the peripheral speed difference between the first and second feed rollers F1 and F2, and the twist added by the false twisting device N exceeds the primary heater H1 and reaches the first feed roller F1. Since it is transmitted retroactively, false twisting and drawing are simultaneously performed in the primary heater H1.

The yarn Y drawn by the second feed roller F2 is fed into the secondary heater H2, and in a set state, is taken up by the third feed roller F3 and oiled by the oiling roller 6, and then wound. In the take-up device W, it is pressed against the fixture roller 7 and wound as a package P.

The threading operation to the secondary heater H2 in the draw false twisting machine 1 configured as described above is performed in the following procedure. First, while the front end of the yarn Y passed through the second field roller F2 is sucked by the suction pipe 10 and locked like Y1, the yarn Y1 is hooked and bent by the yarn hooking tool T shown in FIG. Like Y2, it is brought close to the yarn introduction port H2a of the secondary heater H2. Then, when the yarn Y1 is cut between the yarn hooking tool and the suction pipe 10 while sucking with a suction gun from the outlet side of the secondary heater H2, the yarn Y1 is released from the suction pipe 10 and the yarn Y1 is released. In this way, the thread is pulled into the secondary heater H2, and the threading operation is completed.

However, the yarn Y2 cut during the above work is not attracted by the secondary heater H2 due to a reaction of the cutting or the like and jumps out to the opposite side, interferes with Yb of other yarn paths which are in back-to-back contact, and entangles with each other. The situation happened.

[0009]

[Problems to be solved by the device]

 The present invention has been made in view of the above-mentioned points in the prior art. The purpose of the present invention is to prevent yarn interference between the second feed roller and the secondary heater which are arranged back to back. It is intended to provide a drawn false twisting machine.

[0010]

[Means for Solving the Problems]

 A second feed roller and a secondary heater provided below the second feed roller are provided back to back, and a separator is provided between the feed rollers provided back to back so as to hang down toward the secondary heater.

[0011]

[Action]

 When threading through the secondary heater, if the thread hung on one of the pair of second feed rollers arranged back to back is not drawn into the secondary heater and jumps out to the opposite side, the separator It is prevented from being sent to the other thread side.

[0012]

【Example】

 An example of the embodiment will be described with reference to the drawings.

The drafting false twisting machine of the present invention comprises a separator 11 shown in FIG. 1 depending on the lower surface of a beam 8 provided on a machine stand 2 of the drafting false twisting machine 1 shown in FIG. ..

In FIG. 1, a separator 11 has a flat plate shape, and a pair of left and right brackets 12 formed in an L shape are left and right paired and fixed to both sides with screws 13 and 14, and each bracket 12 is stretched. It is fixed to the lower surface of the beam 8 provided on the machine base 2 of the twisting machine 1 with the screw 15.

The beam 8 is originally for fixing the second feed rollers F2a and F2b. On both side surfaces of the beam 8, the bases 16a of the pair of second feed rollers F2a and F2b, 16b are fixed back to back.

A gap 17 is provided between the lower end of the separator 11 and the secondary heater H2. This is to prevent the heat of the secondary heater H2 from being transferred to the separator 11 and the second feed rollers F2a and F2b connected to the separator 11.

Next, the operation will be described based on the example of the above embodiment.

During the threading operation to the secondary heater H2, for example, when the thread Y threaded on the one second feed roller F2a is sent to the opposite side without being drawn into the secondary heater H2, Since the separator 11 is provided between the two second feed rollers F2a and F2b, the yarn Ya is prevented from being sent to another yarn path Yb which has already been threaded, so that the yarn Ya can be quickly fed. The threading work can be completed.

[0019]

[Effect of the device]

 As described above, the drawn false-twisting machine of the present invention is provided with the second feed roller and the secondary heaters provided therebelow back to back, and a separator is hung between the feed rollers provided back to back to the secondary heater. Since it is provided, it is possible to prevent the yarn from interfering with each other when the yarn is threaded through the secondary heater.
