Abstract:
The corrugated paperboard sheet feeding apparatus comprises: a sheet feeding table; a front guide for regulating a front end of a corrugated paperboard sheet; a back guide for regulating a rear end of the corrugated paperboard sheet; and a guide element for separating the corrugated paperboard sheets so as to form a plurality of separate groups, wherein the guide element includes: a first guide element formed in the front guide to have a first separation guide surface; and a second guide element formed in the back guide to have a cutout portion, and a second separation guide surface, and wherein the cutout portion of the second guide element is formed in such a manner that an amount of concavity thereof is greater than an amount of protrusion of the lower edge of the first separation guide surface of the first guide element.
Abstract:
Provided is a corrugated paperboard sheet printing device which includes a conveyance device for conveying a corrugated paperboard sheet fed out from a sheet feeding device, while suckingly holding the sheet; a plurality of printing units for printing the sheet through a series of printing processes; an information generator for generating basis weight information indicative of a basis weight of a corrugated paperboard sheet in each order; a storage device for storing therein a plurality of correction information for correcting a plurality of printing timings at each of which a respective one of the plurality of printing units performs the printing process on the sheet, in association with the basis weight information; and a controller for, based on the correction information, correcting the printing timing in each of the printing units, and causing the printing unit to operate according to the corrected printing timing.
