Packing method and unit for folding a blank on a packing machine

A packing method and unit for folding a blank on a packing machine; a first suction pickup head engages a first panel of the blank inside a store; a second suction pickup head engages a second panel of the blank inside the store; the pickup heads are moved from a withdrawal position at the store to a release position at a packing conveyor, insert the blank inside a pocket on the packing conveyor; and the blank, folded into a ‘U’, is released inside the pocket on the packing conveyor; as the pickup heads are moved from the withdrawal position to the release position, a relative movement between the first pickup head and the second pickup head is produced to fold the blank into a ‘U’ before the blank is inserted into the pocket on the packing conveyor.

Method and device for forming package bodies open at one end from package sleeves open at both ends

The invention relates to a method for forming package bodies open at one end from package sleeves open at both ends for the manufacture of filled packages. In order to allow packages with a cross section which is neither square nor rectangular to be formed more simply and reliably, the package sleeves are kept ready for further processing in a stack, folded flat along at least two folded edges running in the longitudinal direction of the package sleeve, the flat-folded package sleeves are transferred in succession from the stack to a forming station, the package sleeves are unfolded in a forming station and the unfolded package sleeves are, in the forming station, pushed onto a mandrel in order to close, in particular seal, a longitudinal end of the package sleeve.

Device and method for the shaping of gable surfaces of packages with a slanted gable
11745903 · 2023-09-05 · ·

A device for shaping the gable surfaces of packages with a slanted gable is shown and described, including: a conveyor system with cells fixed to it to receive the packages, at least one gable folder to fold a fin seam in the gable region of the packages and at least two ear folders to fold ears in the gable region of the packages. In order to enable rapid and reliable shaping of the gable even in packages with slanted gables, it is proposed that both the gable folder and the ear folders be mounted movably relative to the conveyor system and the packages to be transported therewith. A method for shaping the gable surfaces of packages with a slanted gable is also shown and described.

Device for the single-sided closure of packaging sleeves for the production of composite packages
10926896 · 2021-02-23 · ·

A device is depicted and described for the single-sided closure of packaging sleeves for the production of composite packages, in particular carton/plastic-composite packages, by forming by means of a mandrel wheel with a plurality of mandrels arranged distributed uniformly over the circumference and directed radially outwards, which pass successively through several processing stations in the circumferential direction of the mandrel wheel, wherein each mandrel has a head on its free end, on which the folding sections to be closed of the packaging sleeve slid onto the mandrel are folded and sealed in the closed position, and wherein the head of the mandrel is designed to be variable in its outer dimensions. In order to reliably ensure a reliable and in particular a pocket-free sealing of the end area of the packaging sleeve on the mandrel, it is provided that at least two corner segments of the head are variable in their position, that the mandrel in its interior has at least one axially movable tappet for the adjustment of the head geometry and that the corner segments of the head are designed as pivot elements, which can be brought from a sealing position into a retracted position.

Method and device for forming package bodies which are open on one side using an oscillating gripper

Described and illustrated is a device for at least partially unfolding package sleeves, having a magazine comprising a stack formed from package sleeves, wherein the package sleeves of the stack are folded flat around at least two folding edges extending in the longitudinal direction of the package sleeves and wherein a gripper is provided for gripping a side of the package sleeves facing away from the stack and for moving, in particular pulling, the package sleeves along a withdrawal transport path with the folding edges into grooves of at least one receptacle of a moulding station and wherein the grooves are spaced so that the folding edges of the package sleeves are spaced apart further in the magazine than in the grooves. In order to further prevent operational malfunctions and allow a more reliable and largely malfunction-free production of packaging bodies which are open on one side from package sleeves which are open on both sides, it is provided that a drive is assigned to the gripper and/or the grooves for moving the package sleeve section gripped by the gripper first along the withdrawal transport path across a groove plane which connects the grooves, then back against the withdrawal transport path across the groove plane, and then again along the withdrawal transport path across the groove plane.
