Abstract

This coiler device provided with a chute guide has: pinch rollers that lead a metal sheet carried in along a path line to a coil-up line that is curved from the path line; a mandrel that is disposed ahead of the coil-up line and coils up the metal sheet; and a chute guide that guides the upward-facing surface side of the metal sheet at the coil-up line and introduces the metal sheet to the coil-up opening of the mandrel. A configuration is adopted such that the chute guide has: a main body frame; and a liner that is attached to the main body frame, forms at least a portion of the guide surface that guides the metal sheet, has a lower coefficient of friction than the main body frame, and has a lower hardness than the metal sheet.

First claim

The invention claimed is:

1. A coiler device provided with a chute guide, comprising:
a pinch roller configured to guide a metal strip being conveyed along a pass line to a winding line bent from the pass line;
a mandrel disposed ahead of the winding line and configured to wind up the metal strip; and
a chute guide configured to guide an upper surface side of the metal strip in the winding line, and to introduce the metal strip into a winding port of the mandrel,
wherein the chute guide comprises
a body frame;
a liner being attached to a downstream end of the body frame in the winding line, said liner constituting at least part of a guide surface to guide the metal strip, said liner having a lower friction coefficient than a friction coefficient of the body frame and a lower hardness than a hardness of the metal strip; and

an attachment unit configured to detachably attach the liner to the body frame, and wherein the attachment unit includes:
a frame body provided to the body frame,
a slide groove provided in the liner,
a slide piece configured to be engaged with the slide groove, and to sandwich the frame body in conjunction with the liner, and
a screw member configured to fasten and fix the slide piece to the liner.

2. The coiler device provided with a chute guide according to claim 1 , wherein
the slide piece includes an engagement protrusion configured to be engaged with the slide groove, and
the slide groove includes
a first opening opened with a larger width than a width of the engagement protrusion, and a second opening opened with a smaller width than the width of the engagement protrusion.

3. The coiler device provided with a chute guide according to claim 2 , wherein
the liner includes a plurality of pieces arranged in a width direction of the winding line, and
the plurality of pieces are detachably attached to the body frame independently of each other.

4. The coiler device provided with a chute guide according to claim 1 , wherein
the liner includes a plurality of pieces arranged in a width direction of the winding line, and
the plurality of pieces are detachably attached to the body frame independently of each other.

5. The coiler device provided with a chute guide according to claim 1 , wherein the liner is attached only at a downstream end of the body frame in the winding line.

6. The coiler device provided with a chute guide according to claim 1 , wherein the liner extends beyond the downstream end of the body frame in the winding line.
