Description

Technical Field

[0001] The present invention relates to a bundle with an axis, and more particularly, to a method for knotting the end wires of the bundle with an axis. Background Art

[0002] like Figure 1 A flexible and extremely long wire 1 made of textile, carbon fiber or other similar materials is continuously wound on a reel 2 to form a bundle 3. The end of the wire 1 is manually wound around the bundle 3, and a knot 5 is tied on the outside of the bundle 3 to prevent the bundle from loosening.

[0003] The thread bundle 3 is manufactured by automated equipment, but the knotting is done manually, which delays production and does not meet the definition of fully automated production. In addition, when the thread bundle 3 is first used, the knot 5 must be cut manually, which is very inconvenient and can easily lead to cutting in the wrong position, resulting in the thread 1 not being able to be released smoothly from the thread reel 3. Summary of the Invention

[0004] In order to solve the above problems, an object of the present invention is to provide a knotting method for axis bundles, which is performed by automated equipment.

[0005] The present invention provides an automated knotting method for a bundle with an axis. The bundle with an axis is formed by continuously winding a flexible and extremely long wire body around the outside of a reel through an automated winding device. The end section of the wire body is released from the bundle with an axis and extends a certain length away from the bundle with an axis, forming a freely extendable and movable end section of the wire body. The knotting method is performed by an automated knotting device, which controls the movement of a positioning rod, a first hook clamp, a second hook clamp, a third hook clamp, and a shearing tool. The knotting method includes the following steps:

[0006] Step 1: The first hook clamps a free end of the terminal wire;

[0007] Step 2: The positioning rod is moved to the position of the last segment of the line;

[0008] Step 3: The first hook clamp controls the final wire segment to rotate 360 ​​degrees, with the rotation direction of the final wire segment being the same as the winding direction of the wire segment on the reel, and the first portion of the final wire segment is wound around the positioning rod and the belt axis bundle, so that the first portion forms a first loop between the positioning rod and the belt axis bundle;

[0009] Step 4: The second hook moves through the first loop and then clamps a second portion of the end wire;

[0010] Step 5: The second hook moves to pull the second portion into a first zigzag section and pass it through the first loop;

[0011] Step 6: the positioning rod leaves the first ring;

[0012] Step 7: The second hook twists the first zigzag section to form a twisted loop;

[0013] Step 8: The third hook moves to pass through the twisting ring and then clamps a third portion of the end wire.

[0014] Step 9: The third hook moves to pull the third portion into a second zigzag section and pass it through the torsion loop;

[0015] Step 10, the second hook releases the twisted loop and retreats;

[0016] Step 11: The third hook clamp rotates the second zigzag section around the belt axis by 180 degrees, with the zigzag direction being the same as the winding direction of the wire on the reel. The third hook clamp tightens the second zigzag section so that the last section of the wire forms a slipknot around the belt axis and tightens the bundle.

[0017] Step 12: The shearing tool cuts the end of the wire between the slipknot and the first hook and retains a wire end connected to the slipknot.

[0018] Efficacy of the present invention:

[0019] The present invention uses an automated method to tie a slipknot on the axis bundle to prevent the axis bundle from loosening. The automated knotting method of the present invention replaces the manual knotting of the prior art.

[0020] The automatic knotting method of the present invention can be configured at the very end of the automatic production line for strapping the axles. When the strapping process is completed, the automatic knotting operation can be performed using the present invention.

[0021] The automatic knotting method of the present invention ties a slipknot on the axis bundle and reserves a thread end. The slipknot can be untied by pulling the thread end away from the slipknot, and the axis bundle is released, so that the thread body can be stretched for use. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0040] To facilitate the description of the central concept of the present invention as presented in the Summary of the Invention, specific embodiments are provided. The various objects in the embodiments are depicted in proportions, sizes, deformations, or displacements appropriate for the purpose of illustration, rather than in scale with actual components. This is to be noted.

[0041] like Figure 2 , a soft and extremely long wire body 10 made of textile, carbon fiber or other similar materials is continuously wound on the outside of a reel 11 by an automated winding device (not shown) to form a bundle with an axis 12. The end of the wire body 10 is released from the bundle with an axis 12 and extends a certain length in the direction away from the bundle with an axis 12 to form a freely extendable and movable end-segment wire body 20. A free end 21 of the end-segment wire body 20 is clamped by a first hook clamp 42 from the beginning to the end of the knotting action. The first hook clamp 42 is controlled by an automated knotting device (not shown).

[0042] In order to highlight the end line 20 in the figure, it is emphasized with a thick black line. Figures 3 to 16 The reason why the thread 10 on the part of the reel 11 is not shown is to clearly depict the knotting action of the last section of the thread 20 in the figure, which will be explained first.

[0043] like Figure 3 A positioning rod 41 is parallel to the axis body 10 and extends to the position of the last segment of the line body 20. The automated knotting device controls the positioning rod 41 to move to the position of the last segment of the line body 20 or to leave the position.

[0044] like Figure 4 The first hook 42 controls the final wire segment 20 to rotate 360 ​​degrees around the positioning rod 41 and the belt axis bundle 12. The rotation direction of the final wire segment 20 is the same as the winding direction of the wire 10 on the reel 11, so that the first portion 22 of the final wire segment 20 forms a first loop 27 between the positioning rod 41 and the belt axis bundle 12.

[0045] like Figure 5 A second hook clamp 43 is parallel to the positioning rod 41, and the automated knotting device controls the reciprocating movement of the second hook clamp 43. The second hook clamp 43 first passes through the first loop 27 and then clamps the second portion 23 of the end segment of the wire body 20;

[0046] like Figure 6 The second hook 43 moves in the opposite direction, pulling the second portion 23 into a first zigzag section 25 and passing it through the first loop 27 .

[0047] like Figure 7 , the positioning rod 41 moves horizontally away from the first ring 27 .

[0048] like Figure 8 The second hook 43 twists the first zigzag section 25 to form a twisted loop 28 .

[0049] like Figure 9 A third hook clamp 44 is parallel to the second hook clamp 43, and the automated knotting device controls the reciprocating movement of the third hook clamp 44. The third hook clamp 44 first passes through the torsion ring 28 and then clamps a third portion 24 of the end wire body 20.

[0050] like Figure 10 , the third hook 44 moves in the opposite direction, pulling the third portion 24 into a second zigzag section 26 and passing it through the torsion ring 28 .

[0051] like Figure 11 The second hook 43 releases the twisting loop 28 and withdraws. Then, the third hook 44 rotates the second curved section 26 around the belt axis bundle 12 by 180 degrees. The direction of rotation is the same as the winding direction of the wire 10 on the reel 11. The third hook 44 tightens the second curved section 26, so that the last section of the wire 20 forms a slipknot 30 around the belt axis bundle 12 and is tightened.

[0052] like Figure 12 The third hook 44 releases the second curved section 26 and retreats, and a shearing tool 45 cuts the end of the line 20 between the slipknot 30 and the first hook 42, forming a line end 31 connected to the slipknot 30. The shearing tool 45 is controlled by the automatic knotting device.

[0053] At this point, the automated action of wrapping the tape axis bundle 12 with the final wire 20 and tying a slip knot 30 on the outside of the tape axis bundle 12 is completed.

[0054] The following Figures 13 to 16 The method of untying the slip knot 30 to release the tape axis bundle 12 is described.

[0055] like Figures 13 to 16 , pull the thread end 31 away from the knot 30 to untie the knot 30, and the axis bundle 12 is released, so that the thread body 10 can be stretched for use.
