Cutting apparatus and automatic cutting system of blade's raw material of blanking die

Abstract

The present invention relates to a cutting apparatus of blade's raw material used in a paper blanking die for manufacturing paper box and the like and an automatic cutting system using this cutting apparatus. This cutting apparatus comprises: cutters more than two kinds having different cutting out or cutting off patterns arranged side by side laterally against a feeding direction of the blade's raw material; a cutter guiding section for guiding said each cutter so as to be able to perpendicularly move against a plane of said blade's raw material; a pressing means for perpendicularly moving and pressing any one of said cutters toward a plane of said blade's raw material; a cutter die for supporting said blade's raw material against the pressing force of said cutter and simultaneously interacting with said cutter whereby executing the cutting work of the blade's raw material; and a cutter selecting means for selecting such that only any one of said cutters is pressed by said pressing means. According to this, various cut patterns of the blade's raw material can be easily and exactly obtained in a single apparatus. And, complete automatization of the cutting work is attained by the automatic cutting system.

1 . A blade's raw material cutting apparatus for cutting out or cutting off of band shaped blade's raw material for paper box blanking die, comprising: 
 cutters of more than two kinds having different cutting out or cutting off patterns arranged side by side laterally to a feeding direction of the blade's raw material;    a cutter guiding section for guiding said each cutter so as to be able to perpendicularly move against a plane of said blade's raw material;    pressing means for perpendicularly moving and pressing any one of said cutters toward said plane of the blade's raw material;    a cutter die for supporting said blade's raw material against the pressing force of said cutter and simultaneously interacting with said cutter and executing the cutting work of the blade's raw material; and    cutter selecting means for selecting only any one of said cutters so as to be pressed by said pressing means.    
     
     
         2 . Cutting apparatus of blade's raw material for a blanking die as defined in  claim 1 , wherein said each cutter moves by resiliently returning by a spring when a pressing force of said pressing means is released.  
     
     
         3 . Cutting apparatus of blade's raw material for a blanking die as defined in  claim 1 , wherein said cutter selecting means comprises: 
 a hydraulic pressure member which is placed between said pressing means and said each cutter, and transfers a pressing force of said pressing means to a corresponding cutter so that it makes a cutting work by the cutter to be possible;    hydraulic pressure member driving means for selectively moving said each hydraulic member to any one position among said pressing force transferable position and a position which does not transfer the pressing force so as to make the cutting work to be impossible; and    a control section for controlling said hydraulic pressure member driving means.    
     
     
         4 . Blade'ds raw material cutting apparatus as defined in  claim 3 , wherein said hydraulic member driving means comprises: 
 a fluid pressure cylinder which is fixedly attached to said each cutter and forwardly and reversely moves the corresponding hydraulic member in horizontal direction against the pressing direction of said pressing member.    
     
     
         5 . Blade's raw material cutting apparatus as defined in claims  3  or  4 , wherein a control section of said hydraulic member driving means comprises: 
 selective switching means for selectively driving each corresponding hydraulic member driving means of said cutters.  
 
     
     
         7 . Blade's raw material cutting apparatus as defined in  claim 4 , wherein said hydraulic member moves by forwardly and reversely sliding on the hydraulic plane of said each cutter.  
     
     
         8 . Blade's raw material cutting apparatus as defined in  claim 1 , further comprising a cutting off cutter for a notch processing.  
     
     
         9 . A blade's raw material automatic cutting system including a cutting apparatus according to any one claim of  claims 1  to  8  for cutting out or cutting off of the blade's raw material for a blanking die, comprising: 
 a blade's raw material feeding device for feeding in measuring way the blade's raw material to be worked by cutting to said cutting device;  
 processing data inputting means for inputting the data in relation to kind and cutting out or cutting off processing position, a bending position and a bending condition of the cutting work to execute the cutting out or cutting off process to the blade's raw material; and  
 control means for controlling said cutting apparatus and the blade's raw material feedig means on the basis of said inputted processing data.  
 
     
     
         10 . Blade's raw material automatic cutting system as defined in  claim 9 , wherein said blade's raw material feeding means comprises: 
 a pair of feeding rollers which places the blade's raw material between them and resiliently pressing and contacting; and    a driving motor for ratatably driving in measuring way said feeding rollers.    
     
     
         11 . Blade's raw material automatic cutting system as defined in  claim 10 , wherein said processing data inputting means comprises: 
 data converting means which receives a pattern designing data of paper pattern to be cut off and formed by the blade or a laser processing data of the paper container blanking die whereby converts into said cutting process data.    
     
     
         12 . Blade's raw material automatic cutting system as defined in any one of  claims 9  to  11 , wherein said control means includes a material data memory for storing a material data of the blade's raw material such as condition, and which compensates the cutting out or cutting off processing position or bending position in accordance with said inputted processing data on the basis of data stored to said material data memory.
