Shaping of containers by folding cardboard sheets
A device for shaping containers by folding cardboard sheets, comprising a folding station for folding cardboard sheets, provided with a die; a handling station for handling said sheets from a store to said folding station, with a frame and at least one gripping head that can be moved on the frame and comprises means for grasping and holding said sheet, and also a punch with a complementary shape so as to interact with the inside of said die. The punch comprises a bearing surface for bearing against the bottom of said grasped sheet. The grasping means is mounted so as to be able to move relative to said punch and free to move in at least one plane parallel to said bearing surface. The invention also relates to a corresponding shaping method.
Box assembly device and method of assembling box
In a box assembly device, a holding mechanism causes one of bottom boards to contact a first jig and folds the bottom board inside, while the holding mechanism holding the box material in a state where the box material is developed in a cylindrical shape from a folded state. The folding mechanism folds the bottom flap inside so as to overlap with one of the bottom boards. The holding mechanism causes the other bottom board to contact the second jig while holding the box material and folds the other bottom board inside and upwardly so as to overlap with the bottom flap to engage the bottom boards with each other.
MAGAZINE FOR PACKS OF BLANKS, AND METHOD FOR MAKING CONTAINERS FROM BLANKS
A magazine for packs of blanks includes a vertical channel configured for inserting and extracting packs of blanks, a succession of groups of supporting parts movable between a retracted position to allow the packs of blanks to move along the channel towards a portion under the supporting part, and an at least partly extracted position, in which the supporting part intercepts a pack of blanks moving down the channel and provides a steady support for the pack of blanks, and transmission means configured to automatically move each supporting part from the retracted position to the at least partly extracted position when the supporting part immediately below it intercepts a respective pack of blanks, thereby defining the steady support.
CARTON BLANK ERECTOR AND FEEDING AND SHUTTLE MACHINE
A carton blank feeding and shuttle machine includes a first driven belt supported by a first plurality of pulleys and a second driven belt supported by a second plurality of pulleys, a first rod attached to the first driven belt and a second rod attached to the second driven belt. Each of the rods extend across the first and second opposing sides. At least one controller controls motions of (a) the first driven belt and (b) the second driven belt, and a plucking head is supported by the first and second rods such that the first and second driven belts create common motion to move the plucking head along a transport path and relative motion to extend and retract the plucking head. 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.
Container forming machine having a blank stacker assembly
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.
METHODS AND MACHINE FOR FORMING CONTAINERS HAVING TOP FLANGE WITH GLUED CORNERS
A container forming apparatus for forming a container from a blank includes a blank transfer station including an adhesive assembly having a plurality of adhesive applicators, and a compression station downstream of the blank transfer station, the compression station including a vertically movable mandrel and a forming tool below the mandrel. The forming tool defines a cavity therein and has an inner profile complementary in shape to an outer profile of the mandrel. Hot-melt adhesive is applied to a surface of the blank as the blank is transferred through the adhesive assembly. The blank is positioned beneath the mandrel, and the mandrel drives the blank downward into the cavity of forming tool. Compression plates fold panels of the blank, and the formed container includes a fully formed top flange.
BOX ERECTING APPARATUS AND METHOD
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.
