Device and method for producing resin-coated cans

Abstract

A device and a method for producing resin-coated cans that make it possible to uniformly cut resin coating when resin-coated cans are trimmed after being pressed. A device for producing resin-coated cans includes a press machine, a trimmer, a chute connecting the trimmer to the press machine, and a cooling device configured to cool at least, of resin-coated cans passing through the chute, portions to be trimmed by the trimmer. A method for producing resin-coated cans, in which the resin-coated cans are conveyed to a trimmer by a chute after being processed by a press machine, includes cooling at least, of the resin-coated cans passing through the chute, portions to be trimmed by the trimmer.

1 . A device for producing resin-coated cans, the device comprising:
 a press machine;   a trimmer;   a chute connecting the trimmer to the press machine; and   a cooling device configured to cool at least, of resin-coated cans passing through the chute, a portion to be trimmed by the trimmer.   
     
     
         2 . The device for producing resin-coated cans according to  claim 1 , wherein the cooling device cools the resin-coated cans with air. 
     
     
         3 . The device for producing resin-coated cans according to  claim 2 , wherein
 the cooling device includes a housing surrounding the chute and blows the air into the housing by a blower.   
     
     
         4 . The device for producing resin-coated cans according to  claim 2 , wherein
 the cooling device includes an air nozzle having a slit shape and blows the air to the portion of the resin-coated cans to be trimmed by the trimmer.   
     
     
         5 . The device for producing resin-coated cans according to  claim 4 , wherein
 a length of the air nozzle having a slit shape is equal to or longer than a circumferential length of each can barrel of the resin-coated cans.   
     
     
         6 . The device for producing resin-coated cans according to  claim 1 , wherein
 the chute has a meandering path.   
     
     
         7 . The device for producing resin-coated cans according to  claim 1 , wherein
 the press machine is a body maker.   
     
     
         8 . A method for producing resin-coated cans, in which the-resin coated can is conveyed to a trimmer by a chute after being processed by a press machine, the method comprising:
 cooling at least, of the resin-coated cans passing through the chute, a portion to be trimmed by the trimmer.   
     
     
         9 . The method for producing resin-coated cans according to  claim 8 , wherein
 the cooling is performed by cooling the resin-coated cans with air.   
     
     
         10 . The method for producing resin-coated cans according to  claim 9 , wherein
 the cooling is performed by blowing air into a housing surrounding the chute by a blower.   
     
     
         11 . The method for producing resin-coated cans according to  claim 9 , wherein
 the cooling is performed by blowing the air through an air nozzle having a slit shape to the portion of the resin-coated cans to be trimmed by the trimmer.   
     
     
         12 . The method for producing resin-coated cans according to  claim 8 , wherein
 the chute has a meandering path, and   in the cooling, cooling is performed while the resin-coated cans pass through the meandering path.   
     
     
         13 . The method for producing resin-coated cans according to  claim 8 , wherein
 in the cooling, cooling is performed to a temperature lower than a glass transition temperature of a resin used for the resin-coated cans.
