Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a down coiler whose mandrel can be directly lifted by a crane and which is easy to maintain.

[Conventional technology]

Until now, down coilers (retract coilers) that could be retracted outside the line to improve maintainability
Some are installed.

Figure 3 shows a conventional retract coiler, in which a indicates a pinch roll installed along the pass line to supply material to the retract coiler, b indicates a coiler frame of the retract coiler, and the coiler frame b is placed on a foundation c. It is provided movably in the direction intersecting the pass line by a base d and a slide liner e. f is a mandrel rotatably provided on the coiler frame b, g is a wrapper roll that wraps the tip of the material around the mandrel f, h is a holding frame for the wrapper roll,
The presser frame h is rotatably supported by the coiler frame b via a fulcrum shaft i in the radial direction of the mandrel, and is connected to an opening/closing cylinder k via a link mechanism j. When performing maintenance, move the coiler frame b back from the line and close the opening/closing cylinder k.
, open the wrapper roll g, and replace the mandrel f, etc. 1 is a clamping device for fixing the coiler frame b to the base c in the winding position.

[Problem that the invention attempts to solve]

As described above, the conventional retract coiler has a structure in which the entire body is retracted, and since it is necessary to prevent interference between the wrapper roll cylinder and its surroundings when retracting, a link mechanism is used in the wrapper roll opening/closing mechanism. For this reason, conventionally there is a problem in that play tends to occur inside the opening/closing mechanism, and the down coiler cannot exhibit its original performance. Furthermore, in the past, the mandrel could not be lifted directly with a crane because the coiler frame was in the way, making the work difficult. The present invention has been made to solve the above problems.

[Means for solving problems]

In order to solve the above-mentioned problems, the present invention fixes a coiler frame to a foundation, in which a plurality of wrapper rolls are installed so that they can be moved close to and away from the mandrel, and a retract frame that can move the mandrel in a direction that intersects the pass line. The retract frame is fixed to the coiler frame at the winding position using a clamp device.

〔Example〕

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

1 and 2 show the present invention, in which a coiler frame 1 is fixed to a foundation 2, and a retract frame 3 is attached to the side of the coiler frame 1.
is provided so as to be movable in the direction intersecting the pass line,
A mandrel 4 and its driving device (consisting of a motor 5, a speed reducer 6, etc.) are installed on the retract frame 3, and the tip of the material is wound around the mandrel 4 by a wrapper roll unit provided in the coiler frame 1, and the mandrel 4 is driven. The material is wound up using the following method. The wrapper roll opening/closing mechanism uses a structure in which a presser frame 8 rotatably supporting the wrapper roll 7 is directly pushed and pulled by an opening/closing cylinder 9 to open and close it around a support shaft 10. A clamp device 11 is provided between the coiler frame 1 and the retract frame 3.

During maintenance, the clamp by the clamp device 11 is released and the retract frame 3 is retreated out of the line.

In this way, during maintenance, the coiler frame 1 is left behind and the mandrel 4 is retreated out of the line, so the wrapper roll and cylinder do not move back and there is no risk of interference with the surroundings.Therefore, there is no need to incorporate a link mechanism into the wrapper roll opening/closing mechanism. It is also possible to eliminate rattling. Furthermore, since there is no obstacle above the mandrel 4 in the retracted position, the mandrel 4 can be directly lifted by a crane.

[Effect of idea]

As mentioned above, according to the present invention, (i) there is no need to incorporate a link mechanism into the latspar roll opening/closing mechanism, which eliminates rattling of the latspar roll, allowing the down coiler to exhibit its original performance; (ii) the mandrel can be moved by a crane. (iii) Since the coiler frame is fixed, the piping and wiring connected to the drive device of the wrapper roll opening/closing mechanism can be fixed. This has the excellent effect of making it easy to perform maintenance and inspection of the down coiler.
