DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vertical kettle continuous drawing method and an apparatus for continuously drawing a linear material through a die, winding the linear material on a rotatable kettle, and continuously drawing.

[0002]

2. Description of the Related Art A vertical pot continuous drawing apparatus 51 is shown in FIGS.
As shown in FIG. 7, a linear material 53 supplied from a pay-off basket 54 is passed through a die 52 and drawn, and the pay-off basket 54 for storing the linear material 53 before drawing is provided. It mainly includes a die 52 for drawing the material 53, a hook 55 for pulling the linear material 53 through the die 52 and winding the same, and a take-up basket 57 for storing the drawn material 58 after drawing.

[0003] A rotatable pressure roll 56 is provided on the side surface of the shuttle 55 to press the drawing material 58 therebetween, and the upper portion rotates at the same angular speed as the shuttle 55 while maintaining a predetermined inclination. A shudding ring 61 is provided. Also, at the lower part of the shuttle 55, the drawing material 5
8 is provided with a gripper arm 59 which grips the tip of 8 and rotates together with the shuttle 55.

A plurality of straightener rolls 62 are provided upstream of the die 52.

In the above-described vertical shuttle continuous drawing apparatus 51, drawing is started by the gripper arm 59 gripping the leading end of the drawing material 58 and rotating together with the shuttle 55 and the shudding ring 61. At the same time, the die 52, the straightener roll 62, and the payoff basket 54 start to rise and rise to the height of the shudding ring 61. Then, when the drawn material 58 is wound around the set number of turns (the number of turns wound around the lower end of the shredding ring 61) on the hook 55, the drawn material 58 wound on the hook 55 is pressed against the hook 55 by the pressure roll 56. Thereafter, the tip of the drawn material 58 is cut in the vicinity of the gripper arm 59. Then, the drawn material 58 separated from the gripper arm 59 starts to fall into the take-up basket 57 rotating at a fixed speed ratio with the rotation angular speed of the shuttle 55. When the above-described movement is completed, continuous drawing becomes possible, and continuous drawing is performed until the linear material 53 in the payoff basket 54 is exhausted.

That is, the drawing material 58 leaves the shuttle 55,
The take-up basket 57 is sequentially moved downward by natural fall to be spirally stored.

[0007]

By the way, the maximum amount of the linear material 53 that can be continuously drawn is determined by the volume of the storage portion inside the take-up basket 57.

[0008] However, in the above vertical kettle continuous drawing method, when the drawing material 58 is stacked in the take-up basket 57 due to the centrifugal force generated by the rotation of the hook 55 and the take-up basket 57, 8
As shown in (2), the drawn material 58 is accommodated in the radially outward direction.

In the case of continuous drawing at a high speed, the drawn material 58 vibrates up and down when it separates from the shuttle 55 and falls continuously into the take-up basket 57. In this case, the stacking performed successively becomes messy, the useless gap increases, and the capacity of the storage portion of the take-up basket 57 cannot be used effectively.

Accordingly, the length of the drawn material 58 to be stored is reduced with respect to the volume of the storage portion of the take-up basket 57, and the amount of the drawn material 58 that can be accommodated in the take-up basket 57 is reduced. There is a problem that the shape material 53 is shortened, which is an obstacle in increasing the material single weight (weight of one material).

Accordingly, the present invention has been devised to solve the above-mentioned problem, and provides a vertical shuttle continuous drawing method and apparatus capable of efficiently storing drawn materials in a take-up basket without gaps. The purpose is to do.

[0012]

Further, a frame 23 having a predetermined length extending and fixed along the outer peripheral surface of the cover body 17 and supporting the traversing rails 22 at both ends thereof is provided. A traversing cylinder 24 for movement is supported via a pin 25. A roll support 27 that is movable along the traverse rail 22 is pin-connected to the tip of the rod 26 of the traverse cylinder 24. As the traversing cylinder 24 expands and contracts, the roll 16 moves together with the roll support 27 using the traversing rail 22 as a guide. When the traversing cylinder 24 is extended, the roll 16 moves forward in the traveling direction of the drawn material 5, and moves backward when retracted. The position of the pressure roll 6 and the roll moving device 18 is such that at the position of the roll 16 when the traversing cylinder 24 is fully extended, the drawn material 5 separated from the shuttle 7 falls into the take-up basket 8 and the traversing cylinder 24 When the roll 16 is completely retracted, the drawn material 5 separated from the shuttle 7 is positioned above the upper end of the take-up basket 8 during the fall.

Next, the vertical shuttle continuous drawing apparatus 1 having the above configuration
Will be described.

First, the straightener roll 12 and the die 4
Is gripped by the gripper arm to rotate the shuttle 7, the shudding ring 15 and the gripper arm in the same direction, and gradually raise the payoff basket 3 and the die box 11. Thereby, the drawn material 5 is spirally wound sequentially from the lower part of the shuttle 7. Then, when the die box 11 is moved up to the height of the shredding ring 15 and the drawn material 5 is wound up to the upper part of the shuttle 7, the pressure roll 6 is moved to the shuttle 7 to remove the drawn material 5. While pressing, the leading end of the drawn material 5 is cut. Here, the drawing material 5 is sandwiched between the shuttle 7 and the pressure roll 6, and is rotated by the shuttle 7 and the pressure roll 6, whereby the drawing material 5 is continuously pulled from the die 4 to be in a state where continuous drawing is possible.

When performing the above-described operation, the traversing cylinder 24 and the access cylinder 29 of the roll moving device 18 are extended so that the roll 16 stands by outside the take-up basket 8 (16a in FIG. 2). Shown).
Then, when the continuous drawing becomes possible as described above, first, the access cylinder 29 is retracted and the roll 16 is retracted.
Is swung onto the take-up basket 8 (in FIG. 2,
16b). Next, the traversing cylinder 24 is retracted,
The roll 16 extending radially inward is moved to the pressure roll 6 side. As a result, the roll 16 moves from the side where the drawn material 5 has fallen into the take-up basket 8 to the side located above the upper end of the take-up basket 8 while the drawn material 5 is falling. It is possible to apply an urging force for dragging the drawn material 5 in the middle of falling and pressing the drawn material 5 downward from above. For this reason, the vertical vibration of the drawn material 5 can be prevented. The urging force is determined by the diameter of the drawing material 5 and the rotation speed of the shuttle 7, and can be adjusted by the amount of retraction of the traversing cylinder 24.

Next, the roll 16 is rotated left and right about the radial direction by extending and retracting the access cylinder 29 (FIG. 3).
reference). When the roll 16 turns to the pressure roll 6, the drawn material 5 is moved to the outer peripheral side of the take-up basket 8, and when the roll 16 turns to the side away from the pressure roll 6, the drawn material 5 becomes 8 to the center. As a result, when the roll 16 is turned in accordance with the amount of drop of the drawn material 5, the drawn material 5 is uniformly arranged from the center side to the outer peripheral side in the take-up basket 8, and is biased to the outer peripheral side as in the conventional case. Can be prevented (see FIG. 4).

In the above-described embodiment, the downward biasing force applied to the drawn material 5 in the course of dropping is adjusted so as to contract and retract the traversing cylinder 24.
7 can be rotated with respect to the traversing rail 22, and as shown in FIG. 5 , the biasing force can be adjusted by changing the height by rotating the roll 16 up and down about the traversing rail 22. can do.

The roll 16 of the guide means 9 is not limited to a circular cross section, but may be a rod-shaped member having a polygonal cross section.

[0034]

In summary, according to the present invention, the roll is provided above the take-up basket and is rotated left and right or up and down to sequentially guide the drawn material, so that the drawn material is taken up. It can be arranged evenly in the basket and can be efficiently accommodated without gaps, and the capacity of the accommodating portion can be used effectively, so that the single material weight (the weight of one material) can be increased. Demonstrates excellent effects.

Further, by applying a biasing force to the drawn material from above by the roll, the vibration of the drawn material can be prevented even at the time of high-speed drawing, so that the drawn material can be prevented from being piled up randomly in the take-up basket. In addition, the drawn material can be efficiently accommodated in the take-up basket without any gap.
