A cardboard box dividing device includes lower conveyors on which a plurality of connected cardboard box bodies are stacked and transported; an upstream side positioning member and a downstream side positioning member movable along a transport direction and a thickness direction of each connected cardboard box body in upstream and downstream portions of the lower conveyors; a positioning drive device capable of independently moving the upstream side positioning member and the downstream side positioning member; a pressing device pressing, from above, the plurality of connected cardboard box bodies stacked on the lower conveyors; a cutting knife disposed along a width direction of the connected cardboard box body and dividing the plurality of connected cardboard box bodies stacked on the lower conveyors into a front part and a rear part; and a lifting/lowering device relatively moving the plurality of connected cardboard box bodies and the cutting knife along an up-down direction.

Disclosed is a corrugated paperboard box making machine which comprises a sheet feeding apparatus, a processing apparatus, a folder-gluer, a counter-ejector for stacking the box-structured corrugated paperboard sheets and separating them as a batch, a speed setting unit for setting a sheet feeding speed, and a control apparatus. The control apparatus is operable to execute a sheet feeding control processing of 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 is greater than an allowable speed, the sheet feeding apparatus such that the sheet feeding operation is stopped at least once after execution of the sheet feeding control processing.

A bale of stock packaging material includes a continuous tube of paperboard material, the continuous tube of paperboard material being flattened and folded back and forth on itself into a fan-folded bale. The continuous tube of paperboard can be a single piece of paperboard with two opposed edges that are folded to overlap with each other. The paperboard material can include a corrugated layer. The opposed edges can be adhered together to form a single seam that runs lengthwise along the continuous tube of paperboard. The adhesive can be applied between the two edges which can join to form the single seam.

The operation result evaluation system comprises: an operation result information generation part configured to generate operation result information including a production count and an achieved operating time period; and an operation result evaluation device for, after completion of production of corrugated paperboard boxes for a given order, evaluating an operation result of the box making machine. The operation result evaluation device is operable to: with respect to each order, calculate an additional operating time period which is a difference between a target operating time period and the achieved operating time period; generate analytical information regarding an operating time period (FIG. 8) in each order; with respect to each of the entirety or part of a given number of orders, generate comparative information (FIG. 9); and cause the generated comparative information to be transmitted to a user terminal.

A machine for transitioning a box cutout from a flat configuration to a collapsed box configuration includes a first drive wheel configured to drive a box cutout towards a plunging area; a plunger configured to apply force to a central portion of a bottom panel of the box cutout so as to fold the box about a lateral bisecting axis and propel at least a portion of the box cutout downward; and opposed second and third drive wheels configured to grab a box cutout propelled downward by the plunger and further draw the box cutout downward into a collapsed box configuration within a collection area. A box cutout transitioned to a collapsed box configuration in this manner may include a bottom panel having plurality of unbroken minor score lines and broken major score lines.

A sheet folding device includes forming belts which are disposed on both sides in a transfer direction of a corrugated board and move to a center side in a width direction of the corrugated board toward a downstream side in the transfer direction to press both end portions in the width direction from an outside so as to bend both the end portions; and a gauge roller group including several gauge rollers which are disposed along the transfer direction and come into contact with outer sides of both bent portions in the width direction of the corrugated board bent by the forming belts. In the several gauge rollers, recessed portions are provided on outer peripheral surfaces of the gauge rollers in a circumferential direction. Positions of the recessed portions are disposed to be offset downward in a vertical direction toward a downstream side in the transfer direction.

A box has a bottom panel, first and second side panels, a front panel, and a rear panel defining an interior space of the box, and a top panel serving as a lid covering the interior space. The top panel includes a front tab having an adhesive strip laterally extending across a distal portion of the front tab for securing the front tab to the front panel when the lid covers the interior space; and lines of perforations extending across a proximal portion of the front tab, the lines of perforation defining a tear strip for releasing the top panel from the front panel. The adhesive strip comprises a protective peelable liner. The adhesive strip extends completely across the proximal portion of the front tab from the first lateral side to the second lateral side.

A counter-ejector comprises: an elevator including a table displaceable in a forward-backward direction parallel to a feeding-out direction; a backward restriction member for restricting a situation where backward edges of corrugated paperboard sheets in a batch are displaced in a direction opposite to the feeding-out direction; table upward-downward movement drive device; a table displacement drive device; and a control device. The control device executes a table downward movement control processing such that the table is displaced backwardly in at least part of a time period when the table is moved downwardly from the hopper part to a table stop position and a time period when the table is stopped at the table stop position, and a table upward movement control processing such that the table is displaced forwardly in a time period when the table is moved upwardly from the table stop position to the hopper part.
