Abstract

This gate device is provided with a guide unit having a guide section that is disposed at the downstream side of pinch rollers at a path line along which a metal sheet is conveyed, opens/closes a coil-up line that is curved from the path line, and guides the upwards-facing surface side of the metal sheet led in to the coil-up line. A configuration is adopted such that the guide unit has a main body frame and a liner that is attached to the main body frame, forms at least a portion of the second guide surface that guides the metal sheet, has a lower coefficient of friction than the main body frame, and has a lower hardness than that of the metal sheet.

First claim

The invention claimed is:

1. A gate device provided with a guide unit, wherein
a guide unit disposed on a downstream side of a pinch roller in a pass line on which a metal strip is conveyed, the guide unit being configured to open and close a winding line bent from the pass line, and to guide an upper surface side of the metal strip introduced into the winding line, and wherein
the guide unit includes
a body frame, and
a liner being attached to the body frame, constituting at least part of a guide surface to guide the metal strip, and 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 wherein

the liner comprises:
a first liner detachably attached to an upstream side of the body frame in the winding line; and
a second liner detachably attached to a downstream side of the body frame in the winding line, and having a larger thickness than a thickness of the first liner.

2. The gate device provided with a guide unit according to claim 1 , wherein
the first liner and the second liner are each formed from 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.

3. A coiler device 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;
the gate device according to claim 1 , configured to open and close the winding line; and
a mandrel disposed ahead of the winding line and configured to wind up the metal strip.

4. A coiler device 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;
the gate device according to claim 2 , configured to open and close the winding line; and
a mandrel disposed ahead of the winding line and configured to wind up the metal strip.
