Abstract

An integrated flattening, cutting, and collecting assembly includes a frame, a conveyor seat, and a processing rack. The processing rack is provided with a flattening cylinder and cutting cylinders, a flattening block cooperating with a steel sheet being conveyed by the conveyor seat, a cutting lift seat disposed beneath the cutting cylinders, the cutting lift seat being provided with a cutter and cutting pressing blocks, and wherein the distance between the two cutting pressing blocks is smaller than the length of the flattening block. In addition, the lower end of the cutter is disposed beneath the lower ends of the cutting pressing blocks, and this distance is the same as the thickness of the steel sheet being conveyed. The cutting pressing blocks can press and hold the steel sheet during cutting, while not affecting the cutting of the cutter, whereby the accuracy of the steel sheet cutting is greatly improved.

First claim

What is claimed is:

1. An integrated flattening, cutting and collecting assembly capable of integrity maintenance, comprises:
a frame provided with a conveyor seat having an upper planar surface for conveying steel sheets;
a processing rack is disposed above said conveyor seat, wherein said processing rack is provided with a flattening cylinder and cutting cylinders in a sequential manner as considered in the conveying direction of said conveyor seat;
a flattening block, having a predetermined length dimension, is mounted upon a lower end portion of said flattening cylinder and is disposed in a plane parallel to said steel sheets being conveyed by said conveyor seat;
a cutting lift seat is mounted upon lower end portions of said cutting cylinders, wherein said cutting lift seat is provided with a cutter and a pair of cutting pressing blocks which are disposed upon opposite sides of said cutter, wherein the distance defined between said pair of cutting pressing blocks is smaller than said predetermined length dimension of said flattening block, a lower end portion of said cutter is disposed beneath said pair of cutting pressing blocks, and the distance that said lower end portion of said cutter is disposed beneath said pair of cutting pressing blocks is equal to the thickness of said steel sheets being conveyed by said conveyor seat;
a downstream end portion of said conveyor seat is operatively associated with a collecting device for collecting cut portions of said steel sheets;
wherein said collecting device comprises a first product collecting box and a second product collecting box disposed toward one side of said first product collecting box, upper end portions of first plates of said first and second product collecting boxes being disposed within the same plane as said upper planar surface of said conveyor seat while second side plates of said first and second product collecting boxes extend above said upper planar surface of said conveyor seat ( 2 );
a pair of horizontally oriented supporting block feed cylinder-piston assemblies are mounted upon external side wall portions of said first product connecting box, pistons of said pair of horizontally oriented supporting block feed cylinder-piston assemblies are connected to a pair of supporting block feed blocks, and said pair of supporting block feed blocks ( 40 ) are connected to first ends of a pair of collecting supporting blocks while second opposite ends of said pair of collecting supporting blocks extend through front and rear walls of said first product collecting box so as to be disposed internally within said first product collecting box, upper surface portions of said collecting supporting blocks being coplanar with said upper planar surface of said conveyor seat, a plurality of supporting block limit balls are provided within said front and rear walls of said first product collecting box for permitting slidable movement of said pair of collecting supporting blocks with respect to said front and rear walls of said first product collecting box; and
a collecting inspection cylinder is mounted within an upper section of said first product collecting box, a collecting detecting lift block is dependently connected to said collecting inspection cylinder, and a plurality of contact sensors are disposed within a predetermined array upon a lower surface portion of said collecting detecting lift block.

2. The integrated flattening, cutting and collecting assembly as set forth in claim 1 , wherein:
a bottom section of said first product collecting box is provided with a plurality of collecting and receiving springs, wherein lower end portions of said plurality of collecting and receiving springs are engaged with a floor portion of said first product collecting box while upper end portions of said plurality of collecting and receiving springs are engaged with a collecting and receiving block and intermediate portions of said plurality of collecting and receiving springs pass through a spring protection block disposed within said first product collecting box.

3. The integrated flattening, cutting and collecting assembly as set forth in claim 1 , wherein:
a pair of cutter inspection slots are respectively defined within front and rear side plates of said processing rack,
a pair of inspection feeding cylinders are mounted upon said front and rear plates of said processing rack for front to back reciprocating movements;
said pair of inspection feeding cylinders are operatively connected to a pair of inspection feeding blocks;
said pair of inspection feeding blocks are operatively connected to a pair of inspection slot blocks which pass through said pair of cutter inspection slots;
opposite inner end portions of said inspection slot blocks are are provided with cut-out regions, having a predetermined depth, disposed beneath said pair of cutting pressing blocks; and
wherein a pair of contact sensors are embedded within said cut-out regions of said opposite inner end portions of said inspection slot blocks, said predetermined depth of said cut-out regions of said inspection slot blocks coinciding with the distance that said lower end portion of said cutter is disposed beneath said pair of cutting pressing blocks.

4. The integrated flattening, cutting and collecting assembly claim 3 , wherein:
a pressure sensor is embedded within said inspection slot block; and
a second contact sensor is embedded within said pressure sensor so as to be located directly beneath a tip portion of said cutter.

5. The integrated flattening, cutting and collecting assembly as set forth in claim 1 , wherein:
said cutting lift seat is provided with a cutter mounting block;
said cutter is mounted upon said cutter mounting block;
a cutter adjusting motor is mounted upon said cutting lift seat;
a screw mounting block is mounted upon said cutting lift seat so as to be disposed opposite said cutter adjusting motor;
a cutter adjusting screw has opposite ends thereof operatively connected to said cutter adjusting motor and said screw mounting block such that said cutter adjusting screw is threadingly engaged internally with said cutter mounting block such that as said cutter adjusting screw is rotated by said cutter adjusting motor, said cutter mounting block will be moved so as to in turn move said cutter.
