Title:
段ボールシート製造装置の反り判定装置，段ボールシート製造装置の反り矯正装置及び段ボールシート製造システム
Document Type and Number:
Japanese Patent JP6691766
Kind Code:
B2
Abstract:
The present invention makes it possible to determine a warp of a corrugated cardboard sheet in a state in which the corrugated cardboard sheet is nearly finished and at an early stage, and to correct the warp precisely and at an early stage on the basis of the warp determination. A warp determination device for a corrugated cardboard sheet manufacturing device is provided with: displacement value measurement method for measuring displacement values of a plurality of corrugated cardboard sheet pieces (24Ca, 24Cb, 24Cc) on the downstream side of a slitter scorer and on the upstream side of a sheet stacking unit; and warp status determination means for dividing a measurement range of the displacement value measurement method according to a width dimension W1 of the plurality of corrugated cardboard sheet pieces (24Ca, 24Cb, 24Cc), allocating the divided measurement ranges to each of the plurality of corrugated cardboard sheet pieces (24Ca, 24Cb, 24Cc), and determining a warped status of the corrugated cardboard sheet pieces (24Ca, 24Cb, 24Cc) for each of the plurality of corrugated cardboard sheet pieces (24Ca, 24Cb, 24Cc) on the basis of measurement values from the displacement value measurement method in the allocated measurement ranges.
