The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A doffing apparatus of a high-speed high-stand fabric take-up device, applicable to a high-speed high-stand fabric take-up device,
wherein said high-speed high-stand fabric take-up device comprises at least: two side-frame casings sitting opposite to each other, a fabric-winding rod, two drive wheels; each end of said fabric-winding rod protrudes a rod shaft; a rabbet is installed on one face of said drive wheel; said rabbet extends to the perimeter of said drive wheel; said rod shaft of said fabric-winding rod can be engaged to said drive wheel via said rabbet; said drive wheels drive said fabric-winding rod to rotate between two said side-frame casings and roll fabric up; and
wherein said doffing apparatus comprises:
a couple of control handles, separately installed on two said side-frame casings, wherein each said control handle has a fixed end and a movable end; said fixed end is fixed to the interior of said side-frame casing, and said movable end projects through an opening of said side-frame casing to the exterior of said side-frame casing;
a couple of safety pins, separately penetrating said drive wheel corresponding thereto, wherein one end of said safety pin is fixed to said control handle, the relative position of said safety pin can be changed via shifting said movable end of said control handle;
a rod, pivotedly installed between two said side-frame casings;
a couple of support brackets, wherein one end of said support bracket is fixed to said rod, and the other end of said support bracket has a longitudinal notch, which is used to support said fabric-winding rod to span between two said support brackets; and
a couple of hydraulic cylinders, separately disposed in two said side-frame casings, wherein one end of said hydraulic cylinder is pivotedly installed to said side-frame casing, and the other end of said hydraulic cylinder has a cylinder shaft, which can move back and forth along said hydraulic cylinder, and the external end of said cylinder shaft is pivotedly installed to said support bracket; and
wherein via said safety pins’ enhancing the connection between said drive wheel and said rod shaft of said fabric-winding rod, the safety of fabric-winding operation can be promoted; via said hydraulic cylinders providing a buffer force to decelerate the rotation speed of said support bracket, the safety of fabric-doffing operation can be promoted.
2. The doffing apparatus of a high-speed high-stand fabric take-up device according to claim 1, further comprising a positioning bolt movably installed to either said side-frame casing, wherein said drive wheel has a positioning hole; when a fabric-doffing operation is to be undertaken, via inserting said positioning bolt into said positioning hole, said rabbet of said drive wheel is oriented to a transverse direction lest said drive wheel rotate again and so that said rod shaft of said fabric-winding rod can be easily disengaged from said rabbet.
