Corrugated paperboard box making machine and sheet feeding control apparatus

A sheet feeding control apparatus for use in a corrugated paperboard box making machine, wherein the corrugated paperboard box making machine comprises:

• a sheet feeding apparatus configured to repeatedly perform a sheet feeding operation that feeds one corrugated paperboard sheet in synchronism with continuous regular operation cycles, each of which corresponds to a length of one sheet feeding operation;
• a processing apparatus positioned downstream of the sheet feeding apparatus, the processing apparatus comprising a processing cylinder configured for rotation to process each of the corrugated paperboard sheets fed from the sheet feeding apparatus;
• a folder-gluer positioned downstream of the processing apparatus and configured to fold and glue each of the processed corrugated paperboard sheets to form each of the processed corrugated paperboard sheets in a box structure;
• a counter-ejector positioned downstream of the folder-gluer and configured to make a stack of the box-structured corrugated paperboard sheets, wherein the counter-ejector is configured to count a number of the box-structured corrugated paperboard sheets fed from the folder-gluer and eject the stack of the box-structured corrugated paperboard sheets when the count reaches a batch-forming sheet number;
• and
• a feeding control mode selector configured to set a feeding control mode to one of a first feeding control mode in which the sheet feeding operation is performed once while the processing cylinder makes a 360 degree rotation, or a second feeding control mode in which the sheet feeding operation is performed more than once while the process cylinder makes a 360 degree rotation;
• and
• a sheet feeding control apparatus programmed to control the sheet feeding apparatus in a set one of the first or second, feeding control mode to continuously produce batches of the box-structured corrugated paperboard sheets to fulfill an order in which an ordered number of the box-structured corrugated paperboard sheets is larger than the batch-forming sheet number, wherein the sheet feeding control apparatus is programmed to stop the sheet feeding operation during a time length equal to at least one operation cycle between two consecutive batches while fulfilling the order when the second feeding control mode is set by the feeding control mode selector.
