Definitions
- the invention relates to a (automatically operated) cutting device for attaching a substantially circumferential cutting path in an outer packaging filled with goods up to a filling level, in particular according to the preamble of claim 1 or 4, wherein the cutting device is set up to produce a first, second , place third and fourth cutting strips in the outer packaging so that they connect to one another and form the circumferential cutting strip in order to cut off a collar and/or window cutout.
- the invention relates to a cutting system for an automated cutting device for attaching cutting strips in side walls of an outer packaging.
- the invention further relates to a method for attaching a circumferential cutting path in an outer packaging filled with goods up to a filling level, in particular in side walls and/or a lid of the outer packaging, by means of a cutting device for attaching a substantially circumferential cutting path, in particular by means of a cutting device of the type mentioned at the beginning.
- the document US 6,694,852 B1 discloses a cutting device with which, on the one hand, an outer packaging can be opened at the top and, on the other hand, the collar of the outer packaging can be cut off.
- an outer packaging can be opened at the top and, on the other hand, the collar of the outer packaging can be cut off.
- several cutting strips are placed in the lid.
- the goods are then removed from the opened outer packaging.
- a circumferential cutting strip is applied to the emptied outer packaging by two opposing cutting units, each of which extends to the middle of the outer packaging, so that the collar of the outer packaging is cut off.
- the cut collar can be removed and the goods can then be placed back in the outer packaging.
- the object of the invention is therefore to provide a cutting device, a cutting system and a method of the type mentioned at the outset, with which the collar of the outer packaging can be cut off in an efficient and reliable manner.
- the cutting device also having a control unit for determining a cutting height, which is set up to control the cutting units in such a way that the circumferential cutting path is attached at the cutting height.
- the cutting device has a positioning device which is set up to position the outer packaging for, in particular simultaneously, attaching the first and second cutting tracks in a first cutting position and for, in particular simultaneously, attaching the third and fourth cutting tracks in a second cutting position.
- An advantage achieved with the invention can be seen in particular in the fact that, on the one hand, a height of the outer packaging filled with goods can be reduced, whereby, for example, volume-optimized outer packaging is provided for shipping, which, on the one hand, reduces the amount of waste generated by the customer and, on the other hand, transport costs. Due to the smaller space requirement of the volume-optimized outer packaging, many outer packages can be delivered in one transport vehicle at the same time, which reduces the number of transport movements and thus also improves the CCh footprint.
- a further advantage achieved with the invention can be seen in particular in the fact that, on the other hand, a lid with which the outer packaging is closed can be opened.
- the box can be opened automatically and, if necessary, then emptied automatically, whereby an increased degree of automation can be achieved, for example in a storage and picking system.
- cutting tracks can be attached to side walls or a lid of outer packaging, which are dimensioned differently and/or filled with different filling heights.
- the cutting device is set up to cut the first cutting path in a first side wall of the side walls, the second cutting path in a second side wall of the side walls, the third cutting path in a third side wall of the side walls and the fourth cutting panel in a fourth side wall of the side walls to cut off the collar.
- the cutting units can be moved parallel to the first cutting direction be so that one of the cutting strips can be attached to opposite side walls of the outer packaging.
- the cutting device is set up to attach the first, second, third and fourth cutting tracks in the lid in order to cut off or cut out the window cutout. This is particularly useful if the outer packaging has a lid.
- the cutting device comprises a conveying device for transporting the outer packaging in a conveying direction, the conveying device being set up to move the outer packaging to the first cutting position and/or from the first cutting position into the second cutting position.
- the cutting device has a second cutting module, which comprises two opposing cutting systems, each with a cutting unit, the cutting units being movable parallel to a second cutting direction, so that a cutting path of the cutting paths can be attached, in particular simultaneously, in opposite side walls of the outer packaging , wherein the first cutting position is arranged in the area, in particular in the effective area, of the first cutting module and the second cutting position is arranged in the area, in particular in the effective area, of the second cutting module.
- the area or effective area of the first or second cutting module is preferably the area in which the respective cutting units, in particular the cutting elements, can act or cut.
- the second cutting module is preferably positioned downstream of the first cutting module in the conveying direction. Alternatively, the first and second cutting modules can be arranged essentially in the same location.
- the cutting systems of the first cutting module and/or the second cutting module are preferably positioned opposite one another in such a way that the outer packaging can be positioned essentially between the cutting units of the opposing cutting systems. It is preferably provided that the cutting units of the opposing cutting systems, in particular of the first cutting module and/or the second cutting module, are each aligned in such a way that their cutting elements are aligned with one another, preferably with the respective cutting edges. This means that the outer packaging is between the cutting elements can be positioned and the cutting elements can be adjusted to opposite side walls of the outer packaging.

- a circumferential cutting path is considered to be a cutting path which is composed of the first, second, third and fourth cutting paths, so that it runs along a peripheral surface of the outer packaging formed by the side walls. “Substantially” in this context means that the cutting path can be interrupted in sections, for example at corners of the outer packaging. It is advantageous if the circumferential cutting path and correspondingly the first, second, third and fourth cutting paths run horizontally. It is advantageous if the cutting device is designed in such a way that the first and second cutting paths can be attached at the same time and/or that the third and fourth cutting paths can be attached at the same time.

- the window cutout is cut out or cut off from the outer packaging by attaching the circumferential cutting strip, so that a window is provided in the lid, through which an interior of the outer packaging is accessible.
- the filling height indicates the height to which the outer packaging is filled with goods.
- the filling height is preferably below an upper edge of the outer packaging. This means that the filling height is usually lower than the height of the outer packaging.
- the cutting height indicates the height at which the circumferential cutting path should be attached.
- the cutting height can, for example, be specified relative to the bottom of the outer packaging.
- the cutting height can be determined if the outer packaging is not yet closed or opened, for example by determining the filling height and setting the cutting height above this.
- the cutting height is preferably between the filling height and the upper edge of the outer packaging if the circumferential cutting strip is to be attached to the side walls, or at the top edge, in particular at the level of the lid, if the circumferential cutting strip is to be attached in the lid.

- the wall thickness of the side walls can correspond to a distance between an outside of the side wall and an inside of the side wall.
- the wall thickness therefore often corresponds in some areas to a single material thickness, in particular cardboard thickness, and/or a double material thickness if, for example, two material layers, in particular cardboard layers, overlap at least in certain areas. The same applies to the wall thickness of the lid.
- the outer packaging identity clearly identifies an outer packaging or indicates the outer packaging type of the respective outer packaging.
- the outer packaging dimension indicates in particular a length, width and/or height of the respective outer packaging or outer packaging type.
- the closed state can indicate whether the outer packaging is opened or closed on one side, for example by a lid. It is advantageous if the cutting device includes an electronic memory. Outer packaging data can be stored in the electronic memory, which is assigned to the outer packaging or the outer packaging types. Those outer packaging data that are stored in the electronic memory can therefore be referred to as stored outer packaging data.
- the control unit can also be set up to determine the cutting height based on the outer packaging data, in particular based on the filling level.

If the first cutting module 4a and the second cutting module 4b are oriented differently, the second cutting direction can enclose a right angle with the first cutting direction in a horizontal plane.
- the outer packaging 2 is preferably fixed by the gripping unit of the lifting device 9.
- step ix the cut-off collar 22 or the cut-off window cutout 24 is lifted off 180 by moving the gripping unit of the lifting device 9, which holds the cut-off collar 22 or window cutout 24, vertically upwards.
- the collar 22 or the window cutout 24 can optionally be transferred to an optional disposal device 10, which is shown schematically in dashed lines in FIGS. 2a and 2b.
- step x) the outer packaging 2 is transported 190 from the second cutting position.
- the now opened or reduced-height outer packaging 2 is essentially removed from the cutting device 1 and, for example, returned to the conveyor system of the storage and picking system.
- the present cutting device 1 or the method described enables the height-reduced outer packaging 2, which is adapted to the filling height H and is therefore volume-optimized, to be closed and, for example, sent to a customer.
- the now opened outer packaging 2 can be emptied, for example, at an automated decanting station, with the goods W being transferred into a storage container, for example.
- the devices shown can also include more or fewer components than shown. In some cases, the devices shown or their components can also be shown out of scale and/or enlarged and/or reduced in size.
