Sheet Package Producing System, Sheet Handling Device, And Fillet Folding Device

Abstract

A sheet package producing system includes at least a cutter module and a packaging module. The cutter module has a cutter blade, for producing X-ray films by cutting a continuous sheet material. The packaging module has packaging robots, for producing a sheet package by packaging the X-ray films stacked on one another. In the sheet package producing system, a first module control unit is incorporated in the cutter module, for controlling the cutter blade. A second module control unit is incorporated in the packaging module, for controlling the packaging robots. A CPU is connected with the first and second module control units removably by a component network, for controlling the cutter module and the packaging module in synchronism.

1 . A fillet folding device for a packaging bag including a bag body for wrapping a sheet stack including plural stacked sheets, and front and rear fillets, formed to protrude forwards and backwards from said bag body, for being folded back on an outside of said bag body, to tighten a wrapped state of said packaging bag, said fillet folding device comprising:
 a conveyor for feeding said packaging bag forwards in a feeding direction;   a centering mechanism, supplied with said packaging bag by said conveyor, for centering said packaging bag by pressing first and second sides thereof with reference to a crosswise direction crosswise to said feeding direction;   a pair of chucks, arranged in said crosswise direction, for clamping first and second end portions of a first fillet selected from said front and rear fillets; and   a chuck moving mechanism for moving said pair of said chucks in synchronism, to fold said first fillet, said first fillet thereby extending and being kept from twisting,   wherein said centering mechanism comprises plates for pressing said first and second sides of said packaging bag.   
   
   
       2 . A fillet folding device as defined in  claim 1 , further comprising a packaging module for inserting said sheet stack into said packaging bag,
 wherein said centering mechanism and said chuck moving mechanism seal said packaging bag from said packaging module, to obtain a sheet package.
