Abstract

PURPOSE:To rationalize an equipment by making the constitution of leading a pair of mandrels alternately to a coiling starting position, of winding a material to the mandrels with a set of wrapper rolls and of releasing the wrapper roll at the mandrel moving time. CONSTITUTION:The tip of a material 11 is wound on wrapper rolls 3a-3d with feeding the material 11 to the mandrel 1a of the rolling starting position 2 from a pinch roll 10. The mandrel 1a is moved to the position of the 2nd mandrel 1b with coiling the material 11 by rotating a rotary frame 4 in the direction 6 with opening the rolls 3a-3d in the position of 3a'-3d' by opening and closing cylinders 8a-8d. On completion of the coiling, the tip of the material 11 is wound on the mandrel 1b which is completed with its movement to the position 2 and the coiling is started. A down coiler can be thus composed of two pieces of mandrels, a set of pinch rolls and wrapper rolls and the equipment expenses are reduced.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a down coiler that uses two mandrels and winds up material alternately.

[Conventional technology]

Conventionally, two down coilers (α) (b) were used to wind up the material continuously sent from the rolling mill, as shown in Figure 2.
) were installed in parallel. (c) is the mandrel of the down coiler, (dl is the wrapper roll of the down coiler, (e)
is the pinch roll provided on the inlet side of the down coiler, (force is the material.

[Problem that the invention seeks to solve]

In this way, conventionally, two dows/coilers and two pinch rolls were each provided, which caused the problem of increased manufacturing costs.

[Means for solving problems]

In view of the above-mentioned circumstances, the present invention was made in order to reduce costs by requiring only one set of pinch rolls and wrapper rolls. The device is equipped with a pair of wrapper rolls for wrapping the material around the mandrel moved to a cutting start position, and a wrapper roll releasing device for releasing the material to a position where it does not interfere with the entire roll of the turban roll when the mandrel is moved.

[For production]

Among the above technical means, the mandrel moving device alternately moves the pair of mandrels to the winding start position. Further, the wrapper roll wraps the leading end of the material around the mandrel at the winding start position. In addition, Rano Haro J' Escape 17cN;y Tsuba-
Move the roll to a position where it won't get in the way of Manotrel's movement.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows the present invention, including a pair of mandrels (1α) (1b) and both mandrels (1G) (1b).
a mandrel moving device that rotates while pivoting, a set of four wrapper rolls (3cL) to (6d) that wrap the tip of the paulownia material around the mandrel that has moved to the winding start position (2), and a set of four wrapper rolls (3cL) to (6d) that The main component is a wrapper roll opening/closing mechanism equipped with a relief device that releases a predetermined wrapper roll to a position where it does not interfere with the mandrel.The mandrel moving device moves a rotating frame (4) that is rotatably supported by a motor ( 5) rotates in the direction (6) to alternately guide the pair of mandrels (1α) and (1b) pivotally supported at both ends of the rotating frame (4) to the winding start position (2). . The Nuranova roll opening/closing Isoguri uses presser frames (7a) to (7d) that pivotally support the wrapper rolls (6α) to (3d), and cylinders (8a, ) to (8d) for opening and closing the Nuranova rolls.
) to rotate the mandrel in the radial direction around the bottle (9), and the two wrapper rolls (i) (3c) located inside the mandrel movement locus.
) opening/closing cylinder (7b>(7c) is the wrapper roll (
3b) (3C) 'rIt has a stroke that allows a large escape to a position where it does not interfere with the movement of the mandrel. α0 is the material αD on the mandrel at the winding start position (2)
It is a pinch roll that feeds.

Next, the operation will be explained.

Drive the pinch roll αO to the first winding start position (2).
The material (11) is sent to the mandrel (ICL) and the tip of the material αD is exposed to the wrapper rolls (3α) to (3d). After that, open/close cylinders (k) to (8d) and clapper rolls (3cL) to (3d) to (5a') to
Open it to the (5♂) position, then open the rotating frame (4) to (
6) Turn in the direction. The first mandrel (3LL) moves from the winding start position (2) to the position of the second mandrel (1b) while winding the material α]), and the second mandrel (1b) starts winding. The direction moves to position (2). While the first mandrel (ILOL) continues winding at the position of the second mandrel (1b) before moving, it is necessary to return the wrapper rolls (3G) to (3d) to the closed position at the winding start position (2). Prepare the first mandrel (1α
), the leading end of the material is immediately wrapped around a second mandrel. The coil wound around the first mandrel (1 cL) is transported to a predetermined location by a coil car or the like.

〔Effect of the invention〕

In the present invention, two mandrels are alternately guided to the winding start position to wind the material and start winding, and only one set of pinch rolls and wrapper rolls is required, which reduces manufacturing costs. It is possible to achieve excellent effects such as being able to reduce
