【Example】

First, referring to Figures 1 and 2, the double tensor of this invention is applied. The doubling machine will be explained.

[0008] A doubling machine has a structure similar to an automatic winder, but it has a yarn feeding package. It is very different in that there are two jis. In other words, the basic structure of the yarn doubling machine is two yarn feeders. Each yarn pulled out from packages 1 and 2 is connected to balloon breakers 12 and 1. 2, it reaches the tensors 15A and 15B, where it is combined and moved by the traversing drum 4. It is wound up into a winding package 3 while being traversed.

[0009] What is shown by the two-dot chain line in Figures 1 and 2 is a line along the lines of multiple doubling machines installed in parallel. Doffing and splicing of the winding package 3 in the full unit. This is a processing robot R.

0010 The processing robot R includes a suction mouth 5, a relay pipe 6, a yarn splicing device 7, and an upper thread A thread separating device 8 and a thread separating device 9 for bobbin thread are provided.

[0011] The yarn splicing device 7 consists of a knotter, a splicer, etc., and the left and right yarn splicing devices 7 are It is installed offset downwards, so that each thread seam is offset forward and backward.

0012 Thread breakage is detected by the thread breakage sensor 13 when replacing the package or when the thread breaks. Then, the processing robot R moves to that unit. suction mouse 5 The unit suctions the yarn on the winding package 3 side, rotates it downward, and connects the yarn. This guides you to the position 7 side.

[0013] At this time, the needle thread separating device 8 operates to prevent the needle thread from being wound on the winding package 3. Each yarn of the book is separated into left and right sides, and each yarn is guided into each yarn splicing device 7.

[0014] The supporting portions of the yarn feeding packages 1 and 2 of this yarn doubling device are connected to the hollow portion of the bobbin from below. A blow-up nozzle 10 that blows out compressed air is connected to the cone. At the time of replacement, the yarn ends stored in the bobbin hollow part of new yarn supply packages 1 and 2 are It is carried to the balloon breaker 12.

[0015] Inside the balloon breaker 12 is an auxiliary blow-up nozzle 1 that blows compressed air upward. 1 is open, and each bobbin thread carried by the blowing nozzle 10 is blown to the thread guide 14. increase.

[0016] The relay pipe 6 has two suction openings, and connects the yarn supply packages 1 and 2 with the yarn. It is provided so as to be rotatable up and down between it and the coupling device 7. When replacing the package or thread When cutting, rotate the suction opening toward the yarn supply packages 1 and 2, and close the suction opening. is positioned above the thread guide 14. And in this position, the auxiliary Fukiage When the yarn from the yarn feeding packages 1 and 2 carried by the puller 11 is sucked, the relay pipe 6 rotates upward while holding each bobbin thread and guides each bobbin thread to the yarn splicing device 7 side.

[0017] At this time, the bobbin thread separating device 9 works to separate each thread of each thread supply package into left and right parts. At the same time, each yarn is guided into each yarn splicing device 7.

[0018] When the yarns from the yarn feeding packages 1 and 2 are thus introduced into the yarn splicing device 7, As shown in FIG. Then, the yarn is joined with the yarn on the package 3 side, and the yarn is spliced.

[0019] In addition, 16 is a yarn cutter, and one of the yarn breakage sensors 13, 13 is When a thread is detected, the other thread is forcibly cut.

[0020] Next, the embodiment of the double tensor of this invention will be fully explained with reference to FIGS. 3 and 4. Ru.

[0021] This double tensor is relatively similar to the upper tensor 15A that provides additional tension. It consists of a lower tensor 15B that applies large tension to the It consists of disks 15a, 15a', 15b, and 15b'.

[0022] One of the bowl-shaped disks 15a and 15b is made of an elastic material 18A made of rubber or the like, nylon or the like. A synthetic resin member 19A or an elastic member 18B such as rubber, or a synthetic resin member 18B such as nylon. The upper tensor lever 17A and the lower tensor lever are connected via the fat member 19B, respectively. -17B is rotatably supported.

[0023] The other bowl-shaped disks 15a', 15b' are connected to the rotating shafts 20A, 20B, respectively. Fixed. The rotating shaft 20B is directly driven by the tensor motor 21, The rotating shaft 20A includes a gear 22 fixed to the rotating shaft 20B, an intermediate gear 23, and a rotating shaft 20. It is indirectly driven by a tensor motor 21 via a gear 24 fixed to A. It's there. Therefore, the bowl-shaped disks 15a', 15b' are tensor motors. 21, and the bowl-shaped disks 15a and 15b pressed against these also rotate. . The rotational speed of the tensor motor 21 is determined by the contact of each bowl-shaped disk surface with the thread. Rotate each tensor 15A, 15B slowly to prevent local wear. It is extremely slow.

[0024] The upper tensor lever 17A, on which the bowl-shaped disc 15a is supported, has its base is loosely fitted on the upper lever shaft 25A, and the bowl-shaped disc is held loosely by the helical spring 26A. 15a' side. Each end of the helical spring 26A is attached to an upper tensor lever. - 17A and the knob 27A, and the knob 27A is inserted and supported by the screw 28. By fixing it to the upper lever shaft 25A, the spring force can be set appropriately. Wear.

[0025] The lower tensor lever 17B, on which the bowl-shaped disc 15b is supported, has its base is loosely fitted on the lower lever shaft 25B, and the bowl-shaped disc is loosely fitted onto the lower lever shaft 25B. 15b' side. Each end of the helical spring 26B is attached to an upper tensor lever. - Supported by the base of 17B and the operation dial 27B, and rotate the operation dial 27B as appropriate. By rotating it, the contact pressure of the lower tensor 15B can be adjusted. That is, a plurality of small depressions 29 are formed in the operation dial 27B, and the operation dial 27B is fixed to the machine frame. The non-rotating member 30 is provided with a plate member having a protrusion 31a at its free end that engages with the recess 29. Fix the base end of the screw 31 and turn the operation dial 27B to move the protrusion 31a into the appropriate depression 2. 9 can be selectively engaged.

[0026] A projecting piece 17A' is formed to hang down from the middle part of the upper tensor lever 17A. , extends to the middle part of the lower tensor lever 17B. This protruding piece 17A' is It works like. In other words, when splicing yarn, etc., the lower tensor is Rotate the lever 17B to separate the bowl-shaped disc 15b from the bowl-shaped disc 15b'. When the lower tensor lever 17B presses the protruding piece 17A', the upper tensor lever 17B The lever 17A rotates to separate the bowl-shaped disc 15a from the bowl-shaped disc 15a'. Ru. Additionally, there is a space between the protruding piece 17A' and the lower tensor lever 17B as shown in FIG. A gap is provided between the bowl-shaped disk 15b and the lower plate as the slab, etc. passes. Even if the tensor lever 17B moves to the left side in FIG. It is made so that it does not collide with piece 17A'. That is, the bowl-shaped disc 15b is Even if it rises from the disk 15b', it does not affect the upper tensor 15A at all and the running Tension is applied to the row yarn by the upper tensor 15A.
