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 for feeding one-by-one corrugated paperboard sheets each having a sheet length specified in accordance with an order;
• a processing apparatus for subjecting each of the corrugated paperboard sheets fed from the sheet feeding apparatus to a given processing;
• a folder-gluer for folding and gluing each of corrugated paperboard sheets subjected to the given processing to form a box structure;
• a counter-ejector for stacking the box-structured corrugated paperboard sheets fed out from the folder-gluer and separating the box-structured corrugated paperboard sheets being stacked, as a batch consisting of a given number of the box-structured corrugated paperboard sheets;
• and
• a speed setting unit for setting a sheet feeding speed at which corrugated paperboard sheets are fed, in advance of execution of the order,
• wherein the sheet feeding control apparatus is configured to execute a sheet feeding control processing of controlling the sheet feeding apparatus such that a sheet feeding operation of feeding one corrugated paperboard sheet is successively repeated a number of times corresponding to the number of the given number of box-structured corrugated paperboard sheets in the batch, and a sheet feeding stop control processing of, when the sheet feeding speed set by the speed setting unit is greater than an allowable speed set based on the sheet length specified in accordance with the order, controlling the sheet feeding apparatus such that the sheet feeding operation is stopped at least once after execution of the sheet feeding control processing.
