DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for inserting a tape core wire for twisting an SZ grooved filament, and more particularly, to twisting an SZ grooved filament. The present invention relates to a method of inserting a rotating tape core.

[0002]

2. Description of the Related Art Reference numerals 14, 1 included in the left half of FIG.
Apparatuses excluding the elements shown in 5, 16, 17, and 19 are conventionally known apparatuses. The main point of the work of dropping and inserting the tape core wire by this device will be described. The SZ grooved striated body 1 is sent from the left to the right in FIG.
A fixed distribution plate 12 and a rotational distribution plate 4 for equiangularly arranging the tape cores 3 are provided. Subsequently, an assembly distribution plate 8 is disposed immediately upstream of the assembly die 9.

[0003] The collecting branch plate 8 is rotatably supported so as to be rotatable around the SZ grooved linear body 1 passing through the center thereof, and a claw 84 protruding from an inner peripheral portion is provided with an SZ grooved linear member. Since it is engaged with the SZ groove 2 of the body 1, the left and right rotations are repeated as the SZ grooved linear body 1 travels in the shape of the SZ groove 2.

[0004] A gear 81 is attached to the outer peripheral portion of the collecting and dividing plate 8, and a spur gear 82 meshes with the gear 81.
The two axes are directly connected to an angle detector 11, such as a rotary encoder or a potentiometer. In this manner, the magnitude of the rotation direction and the rotation angle of the assembly branch plate 8 are constantly measured.

In order for the tape core 3 to be smoothly inserted into the SZ groove 2, it is preferable that the tape core 3 pass in a substantially straight state without being significantly bent at the collecting branch plate 8. For this purpose, it is necessary that the rotary distribution plate 4 located on the upstream side of the assembly distribution plate 8 also rotates in the same direction as the rotation angle of the assembly distribution plate 8.

[0006]

However, the number of the tape cores 3 passing through the rotary dividing plate 4 is considerably large, and these tape cores are wound around the SZ grooved linear body 1 at a high speed and at a speed of one. It is not preferable for the tape core wire and the machine to be swung left and right even at an angle close to the rotation (the angle of the reversal cycle of the SZ groove is around 360 degrees). The greater the distance that the passing position is from the center of rotation, the greater the burden on the tape core and the machine.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described with reference to FIGS. In addition to the elements described in connection with the prior art, a core wire guide tube 5 is rotatably provided at a circumferentially equal position on the outer peripheral portion of the rotary dividing plate 4.

At the entrance of the core guide tube 5, a branch pin 52 for severing the tape cores 3 by one or two sheets is provided across the entrance, and thereafter, one tape core is provided. 3 Step 5 at the exit
In 1, a hollow connecting tube 31 having flexibility and a certain degree of rigidity with respect to rotation about its own central axis is attached between the twisted tube 83 of the collecting and dividing plate 8, The return cylinder 83 is configured to rotate in the same manner as the core guide cylinder 5.

The most important element in this embodiment is a twisting device indicated by reference numeral 14. This is, for example, a device in which a pinch roll is continuously provided in the running direction, or a caterpillar type, which holds the SZ-grooved linear body 1 while running, but suppresses the rotation thereof. By rotating this, the SZ grooved filament 1 can be twisted around its central axis.

Since the SZ-grooved wire 1 is considerably rigid, it cannot be twisted by a large angle, that is, it cannot be twisted.
Can be twisted by an angle (1−k) α with respect to the rotation angle α. Information that the rotation angle of the assembly branch plate 8 is α is transmitted to the drive motor 17 via the amplifying device 18. If the direction of twisting is reversed from the direction of rotation of the assembly liner 8, the rotation angle of the assembly liner 8 will be substantially the difference Δα− (1-
k) α｝ = kα.

The angle kα is measured by an angle detector 11 and amplified by an amplifying device 13 so that the driving motor 1
0, and rotates the rotating distribution plate 4 through the driving gear 42 in the same direction as the collective distribution plate 8 by the same angle.
In other words, the forward and reverse periodic reversal angle of the rotating distribution plate 4 can be reduced by (1−k) α by the action of the twisting device 14.

In this embodiment, a core guide tube 5 for guiding the tape core 3 is rotated by a planetary gear mechanism. That is, the gear engraved on the outer periphery of the core wire guide tube 5 rotatably provided on the outer peripheral portion of the rotary dividing plate 4 is independently provided on the inner peripheral portion of the rotary dividing plate 4 via the idle gear 6. It is configured to mesh with the fixed sun gear 7 and to rotate in the opposite direction as the rotation dividing plate 4 rotates.

A gear portion 41 is provided on the outer periphery of the rotary dividing plate 4, and a spur gear 42, which is rotationally driven by a suitable reversible drive motor 10 such as a servomotor, is provided on the gear portion 41.
Are engaged and rotated by this.

At the center of the sun gear 7, a center hole through which the SZ grooved linear body 1 passes is of course provided, and the ratio of the number of teeth to the planetary gear is appropriately set. This makes it possible to give a desired size of twist to the tape core wire 3.

The mechanism for rotating the core guide tube 5 is not limited to the planetary gear mechanism. For example, it is also possible to wrap a separately driven timing belt around each core wire guide tube 5.

If the gear ratio of the planetary gear mechanism is, for example, 1: 1.
In this case, the core wire guide cylinder 5 rotates in the opposite direction by an angle equal to the rotation angle of the rotation dividing plate 4. That is, the twisting rate in this case is 100%. This twisting is transmitted as it is to the twisting cylinder 83 of the collecting and dividing plate 8 by the presence of the connecting tube 31. Since the sun gear 7 can be rotated by the drive motor 16 through the hollow cylinder 20 again, the drive motor 16
The degree of twisting can, of course, vary when the begins to rotate.

Further, the twist angle ｛(1)
−k) α｝ is measured by the angle detector 15, amplified by the amplifying device 19 and transmitted to the drive motor 16,
By rotating the sun gear 7, it is possible to change the number of twisting rotations of the core wire guide tube 5 according to the rotation of the rotating distribution plate 4.

[0020]

According to the present invention, since the SZ-grooved wire itself can be twisted around its central axis by the twisting device, the rotation angle of the collecting branch plate can be reduced. Therefore, the rotation angle of the rotating distribution plate can also be reduced. As a result, when the tape core is inserted into the SZ grooved striated body, the tape core is not swung to the left or right by a large angle, and there is an advantage that favorable results can be obtained for the tape core and the device.

Further, since an appropriate twist is applied to each tape core 3, no harmful torsional stress remains in the tape core, and as a result, insertion failure into the SZ groove due to elastic pop-out occurs. Further, there is an advantage that defects such as deterioration of the transmission characteristics of the tape core wire itself can be eliminated.
