Abstract
Method for adjusting cutting dies, in particular in a die cutting machine equipped with several simultaneously operated cutting dies (3A-3B), whereby the differences in height of the cutting dies are offset by means of a compensating sheet (13) made of a compressible material working in conjunction with the cutting dies (3A-3B), characterized in that a sheet made of polycarbonate or a material on the basis of polycarbonate is used as a compensating sheet (13).
Description
~ I (J i~J
Method for adjusting cutting dies, compensating sheet used to this end and die cutting machine equipped with such a compensating sheet.
The present invention concerns a method for adjusting cutting dies, in particular in a die cutting machine equipped with several simultaneously operated cutting dies, a compensating sheet used to this end, as well as a die cutting machine equipped with such a compensating sheet.
I~ the first place, the invention is designed to be applied for the die cutting of paper and/or boxboard, for example to form cartons, such as folding cartons and such, out of a sheet or roll of cardboard or corrugated board, or for the die- cutting of any other material which can be processed on bending/die cutting machines and similar cutting machines.
It is known that for the die cutting of cardboard, use is made of a cutting forme in which several cutting dies and/or bending, scoring or embossing formes are provided, as well as a metal cutting plate provided against the backsides of the cutting dies and the cutting forme and which can be moved by means of a press-on system. During the die cutting, the cutting dies go through the cardboard, after which they make contact with a typically hard, usually metal base. It is hereby of primary importance that all the cutting edges of the cutting dies make contact with the base at the end of the die- cutting movement. Otherwise, a number of cuts will be 220 ' ~1 G
incomplete.
Due to inaccuracies and/or wear and tear of the cutting dies and due to tolerances, deviations and/or wear of the parts of the die cutting machine concerned, the above-mentioned demand will in fact be hardly or never met right away, at least when no compensation is provided for.
According to a known method, of which a number of embodiments are described in the documents US 4.955.855, EP 0 125 667, EP 0 297 324, EP 0 655 303 and WO 91/03358, the differences in height of the cutting dies are offset by means of a compensating sheet made of a compressible material working in conjunction with the cutting dies.
By using such a compensating sheet, those cutting dies which stick out the most can be easily set back, so that all the cutting dies make contact with the above-mentioned base with their cutting edges.
According to the known method, use is made of compensating sheets or compensating foils made of polyurethane, metal, tetrafluoroethylene, paper or a combination thereof.
It has been revealed in practice that the use of compensating sheets made of these materials do not meet the required demands in many cases, especially when die cutting boxboard. In many cases, the use of the existing compensating sheets either results in an insufficient compensation or in a too heavy load on the cutting edges of the cutting dies. In both cases, this leads to an incomplete cut, in the first case because certain cutting dies do not go entirely through the material to be cut, - 220101~3 and in the second case because a number of the cutting edges become blunt.
The invention aims among others to remedy this problem.
To this end, the invention concerns a method for adjusting cutting dies, in particular in a die cutting machine equipped with several simultaneously operated cutting dies, which preferably work in conjunction with a base during the die cutting, whereby the differences in height of the cutting dies are offset by means of a compensating sheet made of a compressible material working in conjunction with the backsides of the cutting dies, characterized in that a sheet made of polycarbonate or a material on the basis of polycarbonate is used as a compensating sheet.
By applying a compensating sheet made of polycarbonate according to the invention, particularly good adjusting qualities are obtained. In particular, a perfect compensation is obtained without any damage to the cutting dies.
Moreover, the invention also concerns a compensating sheet to realize the above-mentioned method with, as well as a die cutting machine whose characteristics will become clear from the following description.
In order to better explain the characteristics of the invention, the following preferred embodiment of the invention is described as an example only without being limitative in any way, with reference to the accompanying drawings, in which:

Moreover, the invention also concerns a compensating sheet to realize the above-mentioned method with, as well as a die cutting machine whose characteristics will become clear from the following description.
In order to better explain the characteristics of the invention, the following preferred embodiment of the invention is described as an example only without being limitative in any way, with reference to the accompanying drawings, in which:
2 2 û ~ Q ~ ~
figures 1, 2 and 3 schematically represent three steps of the method.
As represented in figure 1, it is known that when die cutting a material 1, in particular paper and cardboard, as well as corrugated board, use can be made of a cutting forme 2 in which several cutting dies 3A-3B are provided, as well as a metal cutting plate 4 working in conjunction therewith, provided against the backsides 5 of the cutting dies 3A-3B and the backside of the cutting forme 2, for example by means of fixing means such as bolts 6, and which can be moved by means of press-on means 7, with for example what is called a top platen 8 and a makeready 9.
The material 1 to be die cut is provided under the cutting dies 3A-3B on a usually very hard base 10 which is supported either directly or indirectly by the machine frame or the lower platen 11. A supporting plate, for example made of steel or plastic, can be either or not provided between the base 10 and the lower platen 11.
As described in the introduction, the cutting edges 12 of the cutting dies 3A-3B are initially not all situated at the same distance from the base 9. AS represented in figure 1, for example the cutting edges 12 of a number of cutting dies 3B may be situated at a larger distance from the base 10 than the cutting edges 12 of the other cutting dies 3A, due to tolerance differences in the cutting dies or due to wear and tear. Similar differences may occur due to deviations in the machine parts, such as for example the base 10 or other machine parts nat being flat. In fact, we are speaking of differences of some one hundredths to tenths of a 220 1 0 1 ~' millimetre.
In order to compensate for these differences, it is known to provide a compensating sheet 13 between the cutting forme 2 and the cutting plate 4.
In order to offer an optimal compensation, use is made of a compensating sheet 13 according to the invention which consists of polycarbonate or a material on the basis of polycarbonate.
Other components may be added to the polycarbonate, such as colorants, additives which promote the processability and the shaping of the sheets, or even other base components. Preferably, however, the material of the compensating sheet 13 predominantly consists of polycarbonate in this case as well.
Better still, pure or almost pure polycarbonate will be used.
The thickness D of the compensating sheet, which is exaggerated in the figures for clarity~s sake, preferably amounts to 0.1 to 1 mm, and better still to 0.4 to 0.6 mm, and according to the most preferred embodiment to 0.5 mm.
This relatively reduced thickness offers the advantage, apart from optimal compensating qualities, that such a compensating sheet 13 can be used in any existing die cutting machine, since the parts of such die cutting machines are usually made such that this thickness is acceptable, even when said die cutting machine was originally not designed to be equipped with a ~U~UI~
compensating sheet.
The compensating sheet 13 is preferably put directly into contact with the backsides 5 of the cutting dies 3A-3B, i.e. without any other compensating layers being included, as differences in height can be set off immediately there.
Preferably, cutting dies 3A-3B with blunt, flat backsides 5 are used, as this offers optimal compensation qualities in combination with the typical toughness and hardness of polycarbonate.
If required for the fixing of the cutting formes 2 by means of bolts in the manner shown, pre-formed openings 14 can be provided for the bolts 6 or for any other penetrating elements.
During the die cutting movement, the situations as represented in figures 1 to 3 successively occur.
After a compensating sheet 13 has been applied, and as the movement begins, the situation as represented in figure 1 occurs.
As represented in figure 2, the cutting dies 3A which stick out the most will go first through the material 1.
By applying a suitable die cutting pressure, also all the other cutting dies 3B will be subsequently pressed entirely through the material 1, as is represented in figure 5, which is possible because the backsides 5 of the cutting dies which previously stuck out further, in this case 3A, are pressed in the compensating sheet 13.
22,JlU~
By making use of a compensating sheet made of polycarbonate according to the invention, it is obtained that the differences in height of the cutting dies, plane parallelism deviations, machine distortions and/or inaccuracies are perfectly compensated for, so that very precise cuts are finally obtained.
According to the invention, the die cutting pressure is preferably systematically increased at the transition from the situation in figure 2 to that in figure 3 until all the cutting dies 3A-3B go through the material 1.
Thanks to such a temporary, systematic increase of pressure, a pressure can be applied which is just sufficient, which may possibly be maintained for the following cycles, and it can be excluded that a pressure which is bigger than necessary is applied for the cutting and that the cutting edges are loaded more heavily than necessary. Thus is also avoided that cutting dies are pressed into pieces.
The use of polycarbonate is advantageous in that, in particular when die cutting boxboard products, the cutting dies 3A-3B can go through the material 1 to be die cut without any or hardly any compression of said material. Such a polycarbonate sheet offers just enough resistance to let the cutting dies 3A-3B cut through the boxboard material, but it is still sufficiently soft so as not to damage the cutting edges 12 on the base 10 when the pressure is increased.
To sum up, it may be said that polycarbonate provides the best results, especially when die cutting paper or boxboard, both solid cardboard and corrugated board.
22 3 1 0 1 ~;
It is clear that the invention concerns the above-described method and the compensating sheet 13 used thereby, as well as die cutting machines equipped with such a compensating sheet 13 and which are possibly equipped to this end with special features for the application of such a compensating sheet 13.
Although the invention was described above on the basis of what is called a flat-bed die cutting machine, it is not excluded to apply it in rotary die cutting machines.
The cutting dies 3A-3B must not necessarily have a sharp cutting edge 12. They can also be impress knives, for example to realize folding lines or embossing formes.
The term "compensating sheet~ is to be interpreted in a broad sense according to the invention. The compensating sheet according to the invention may also consist of a polycarbonate coating provided on a base sheet or of a layer in the form of a foil.
The present invention is by no means restricted to the embodiments described as an example and represented in the accompanying drawings; on the contrary, such a method and such a compensating sheet can be made in all sorts of variants while still r~m~'n'ng within the scope of the invention.
figures 1, 2 and 3 schematically represent three steps of the method.
As represented in figure 1, it is known that when die cutting a material 1, in particular paper and cardboard, as well as corrugated board, use can be made of a cutting forme 2 in which several cutting dies 3A-3B are provided, as well as a metal cutting plate 4 working in conjunction therewith, provided against the backsides 5 of the cutting dies 3A-3B and the backside of the cutting forme 2, for example by means of fixing means such as bolts 6, and which can be moved by means of press-on means 7, with for example what is called a top platen 8 and a makeready 9.
The material 1 to be die cut is provided under the cutting dies 3A-3B on a usually very hard base 10 which is supported either directly or indirectly by the machine frame or the lower platen 11. A supporting plate, for example made of steel or plastic, can be either or not provided between the base 10 and the lower platen 11.
As described in the introduction, the cutting edges 12 of the cutting dies 3A-3B are initially not all situated at the same distance from the base 9. AS represented in figure 1, for example the cutting edges 12 of a number of cutting dies 3B may be situated at a larger distance from the base 10 than the cutting edges 12 of the other cutting dies 3A, due to tolerance differences in the cutting dies or due to wear and tear. Similar differences may occur due to deviations in the machine parts, such as for example the base 10 or other machine parts nat being flat. In fact, we are speaking of differences of some one hundredths to tenths of a 220 1 0 1 ~' millimetre.
