Defective product removing device for box making machine and box making machine

Abstract

There is provided a defective product removing device for a box macking machine that removes a sheet material as a defective product from a manufacturing line for manufacturing a box by processing the sheet material, the defective product removing device including: a quality determining device for determining the quality of the sheet material based on a predetermined inspection result with respect to the sheet material conveyed in the manufacturing line; a defective product removing portion for removing the sheet material of which a surface is subjected to creasing processing and slotting and which is not folded yet from the manufacturing line; and a sorting device for operating the defective product removing portion with respect to the sheet material determined as a defective product by the quality determining device.

1 . A defective product removing device for a box macking machine that removes a sheet material as a defective product from a manufacturing line for manufacturing a box by processing the sheet material, the defective product removing device comprising:
 a quality determining device for determining the quality of the sheet material based on a predetermined inspection result with respect to the sheet material conveyed in the manufacturing line;   a defective product removing portion for removing the sheet material of which a surface is subjected to creasing processing and slotting and which is not folded yet from the manufacturing line; and   a sorting device for operating the defective product removing portion with respect to the sheet material determined as a defective product by the quality determining device.   
     
     
         2 . The defective product removing device  according to  claim 1 ,
 wherein the defective product removing portion is configured to remove the sheet material from the manufacturing line before adhering is performed on an adhering portion of the sheet material.   
     
     
         3 . The defective product removing device  according to  claim 1 ,
 wherein the defective product removing portion is configured to remove the sheet material which is subjected to adhering at an adhering portion of the sheet material and is not folded yet from the manufacturing line.   
     
     
         4 . The defective product removing device according to  claim 1 ,
 wherein the quality determining device is configured to perform at least one determination of a feeding failure, a printing failure, a defective slotting position, a defective die cutting position, and a gluing failure with respect to the sheet material.   
     
     
         5 . A box macking machine comprising:
 a feeder unit for supplying a sheet material;   a printing portion for performing printing on the sheet material;   a delivery unit for performing creasing processing and slotting on a surface of the sheet material;   a folding portion for forming a box by folding the sheet material and bonding the ends thereof to each other;   a counter ejector for stacking the box while counting the number thereof  so as to discharge the box every predetermined number;   a quality determining device for determining the quality of the sheet material based on a predetermined inspection result with respect to the sheet material;   a defective product removing portion for removing the sheet material of which a surface is subjected to creasing processing and slotting and which is not folded yet from the manufacturing line; and   a sorting device for operating the defective product removing portion with respect to the sheet material determined as a defective product by the quality determining device.   
     
     
         6 . The defective product removing device according to  claim 2 ,
 wherein the quality determining device is configured to perform at least one determination of a feeding failure, a printing failure, a defective slotting position, a defective die cutting position, and a gluing failure with respect to the sheet material.   
     
     
         7 . The defective product removing device according to  claim 3 ,
 wherein the quality determining device is configured to perform at least one determination of a feeding failure, a printing failure, a defective slotting position, a defective die cutting position, and a gluing failure with respect to the sheet material.
