CORRUGATED PAPERBOARD BOX MAKING MACHINE, AND INTER-SHEET PACING DEVICE THEREFOR

摘要

Provided is a corrugated paperboard box making machine which comprises: a cutting device for cutting one corrugated paperboard sheet into a plurality of small-size corrugated paperboard sheets along a direction perpendicular to a predetermined transport direction; a folder-gluer for bending and gluing each of the cut small-size corrugated paperboard sheets; a counter-ejector for stacking the glued small-size corrugated paperboard sheets to form a batch of the small-size corrugated paperboard sheets; and an inter-sheet spacing device for spacing the small-size corrugated paperboard sheets apart from each other, between the folder-gluer and the counter-ejector. The inter-sheet spacing device comprises a transport section for transporting the small-size corrugated paperboard sheets from the folder-gluer to the counter-ejector, and a speed adjustment section for adjusting a transport speed in at least one of the folder-gluey and the transport section so that the transport speed in the transport section becomes greater than that in the folder-gluey.

主权项

1. A corrugated paperboard box making machine comprising:
a cutting device for cutting one corrugated paperboard sheet, to which a plurality of types of processes are applied in sequence while the one corrugated paperboard sheet is transported in a predetermined transport direction, into a plurality of small-size corrugated paperboard sheets along a direction perpendicular to the predetermined transport direction; a folder-gluer for bending and gluing each of the small-size corrugated paperboard sheets, while the small-size corrugated paperboard sheets are transported; a counter-ejector for stacking the glued small-size corrugated paperboard sheets to form a batch having a predetermined number of the glued small-size corrugated paperboard sheets; and an inter-sheet spacing device for spacing the small-size corrugated paperboard sheets apart from each other, between the folder-gluer and the counter-ejector, the inter-sheet spacing device comprising a transport section for transporting the small-size corrugated paperboard sheets from the folder-gluer to the counter-ejector, and a speed adjustment section for adjusting a transport speed in at least one of the folder-gluer and the transport section so that the transport speed in the transport section becomes greater than that in the folder-gluer.
