This severing device (1) includes an upper pressing member (2), a pile support part (4) having a plurality of conveying members (10) for conveying the pile in a conveying direction (X), a lower pressing member (6) arranged under the conveying members (10). The conveying members (10) are juxtaposed in a transverse direction. Two juxtaposed conveying members can be parted. The lower pressing member (6) has: i) two adjacent lower plates (6.1, 6.2) that can be moved apart, and ii) a lower translation actuator (6.3) for moving the lower plates (6.1, 6.2) so as to cause the severance slot (2.0) between juxtaposed conveying members to coincide with a frangible line in the plate.

An apparatus and method for expanding a box blank into a box, the apparatus comprising an arm assembly, a controller, a camera and a box blank conveyor. The arm assembly includes a folding arm having a position in a first direction and a rotational angle controlled by the controller based on a position of a feature of the box blank in the field of view of the camera. The camera captures images of the box blank which are used to position the arm assembly and to evaluate the need to reject a box blank.

A supply apparatus that supplies corrugated cardboard sheets to a supply position in a box-making section that opens folded corrugated cardboard sheets and makes boxes. The supply apparatus comprises a conveying unit, a drive unit, and a control unit. The conveying unit conveys a plurality of the corrugated cardboard sheets to the supply position with the corrugated cardboard sheets stacked. The drive unit drives the conveying unit. A controller, serving as the control unit, estimates the total quantity of the plurality of stacked corrugated cardboard sheets on a conveying surface of the conveying unit. The controller acquires a value pertaining to the drive force of the drive unit when the drive unit drives the conveying unit, and estimates the total quantity of the plurality of stacked corrugated cardboard sheets on the basis of the acquired value.

The present invention relates to a device for removing a box or box part with a polygonal section from a chuck (51) comprising an upper face (511), an application face (510) interconnected by lateral faces and an end face (514), a chuck whereon the box has been previously formed from a blank (1). It comprises a plate (64) comprising first gripping means and translatably movable between a deployed position wherein the plate is near the end face (514) of the chuck whereon the lateral flaps (16a to 16d) are intended to be folded and folded position wherein the plate (64) is away from the chuck (51). The chuck (51) itself is movable between a first forming position wherein the outer cross-section thereof corresponds to the inner cross-section of the box or box part and a second retracted position wherein the outer cross-section thereof is smaller than the inner cross-section of the box or box part.

A carton feeding and shuttle machine includes first and second servo drives for driving first and second belts positioned on a plurality of pulleys, a first block attached to the first belt and supporting a first support shaft and a second block attached to the second belt and supporting a second support shaft. A controller controls the servo drives for driving the first and second belts. A linkage assembly includes a plurality of links configured to move a plucking head along a shaft in response to movements of the first and second belts. Specifically, relative movement of the first and second belts pivots first and third links about a first support shaft and second and fourth links about a second support shaft drawing a base along a slide shaft and extending the plucking head from a first position to a second position for engaging a carton blank in a carton blank stack.

A method of at least partially erecting a carton with a carton forming system includes loading a blank in a blank infeed assembly, the blank having a plurality of panels and a plurality of end flaps foldably connected to a respective panel of the plurality of panels. The method further includes positioning the blank on at least one conveyor assembly, operating the at least one conveyor assembly to move the blank in a downstream direction of the system toward a carton erection assembly, the carton erection assembly including an end flap engagement assembly positioned adjacent the at least one conveyor assembly, and rotating the end flap engagement assembly such that a portion of the end flap engagement assembly contacts and moves at least one end flap of the plurality of end flaps of the blank as the blank moves in the downstream direction.

A paperboard blank stacker assembly for supplying a stack of paperboard blanks to a container forming machine includes a stacker. The stacker has multiple blank stops arranged to hold a peripheral edge of a bottom blank of the stack of paperboard blanks, with the multiple blank stops defining an interior region. A blank carrier has at least one suction device moveable into a grasp position, where the suction device applies a suction force to the bottom blank, and a removal position, where the suction device is moved to remove the bottom blank from the stack of paperboard blanks by pulling the bottom blank through the interior region.

A machine for forming cardboard boxes (B) from flat plates (P), which comprises a feeder of plates with a loader of plates, a sucker mechanism and a conveyor of plates; and a box forming station with a male device with a first rotary electric motor coupled to a first rotational monitoring device, and a male vertically insertable in a mold to form the boxes (B). A pusher member of the conveyor and a suction head of the suction mechanism are both movable by a same second rotary electric motor coupled to a second rotational monitoring device. The first rotary electric motor (11), the second rotary electric motor, the first rotational monitoring device and the second rotational monitoring device are jointly configured to controllably move the male independently of the controlled and synchronized movement of the pusher member and the suction head.
