Definitions
- the present invention relates to a notch cutting device for cutting packaging materials, as in the preamble of the independent claim 1 is defined (see e.g. EP-A-615 910).
- Packaging such as Yogurt cups are often used these days produced by forming and singling from a film strand.
- the films used are general Plastic or metal foils, for example made of polystyrene, Polyethylene, polypropylene or aluminum, and in particular Composites of it.
- Notch cut devices are used for separating packaging used that a matrix and a Knife part with a variety of knives and stamps.
- the packaging material strand in which the individual Packaging is usually already formed is inserted between the die and the knife part.
- the die and the knife part are on top of each other moved, causing the packaging material to be trapped by the stamps are punched and cut by the knives.
- the die and the knife part are moved apart again, making sure that the packaging material from the knife part and the die so that the packaging material strand can be advanced further can.
- the loosening of the packaging material is, for example on the side of the knife part by resilient wipers and on the part of the die by pulling the latter away.
- the packaging material can either be complete can be cut or it can even be scored, i.e. be cut, the latter for training leads from separation points, such as of coherent yogurt cups are known. If a Knives the packaging material when making a cut completely cut or just cut, depends on how close the die and the knife are to each other can be introduced, depending on the packaging material it at different minimum distances from the die and knives for a complete cut of the same comes.
- Notch cut devices are within the scope of the invention based on the following task.
- a notch cutting device must be created of the type mentioned at the outset, if possible low wear of the knives a clean Cut execution with high process reliability in particular even with tough packaging materials.
- the essence of the invention is that in a notch cutting device for cutting packaging materials, with a die and a knife part that is at least has two knives arranged on a tool plate, where the die and the knife part for execution of a cut are movable relative to each other, at least one of the knives in the knife part on a gas cushion the tool plate is mounted depending on the force, so that its Position opposite the tool plate itself depending by touching a packaging material or the force generated by the die is changed in a defined manner.
- Knives arranged depending on the force depending on the from the packaging material or from the die to the knife exerted force change its position, i.e. retreat can unnecessarily high forces on the knife and thus unnecessary material stress and unnecessary wear, especially material fatigue and deformation the knife edge can be avoided or minimized.
- the notch cutting device is advantageously designed in this way and controlled that the at least one force-dependent Knife when making a cut Moving the knife part and the die in contact comes with the die.
- the complete merge of the knife and the die has a clean cut also of tough packaging materials.
- each is the one when making a cut Knives in contact with the die in the knife part individually or in groups with other knives via a gas cushion on the tool plate depending on the force stored so that its location opposite a tool plate yourself depending on the one touch with packaging material or the matrix Strength changes.
- the matrix can then be fully attached all these knives are brought up or all these knives can be brought all the way to the die.
- the notch cutting device advantageously has means for Setting a maximum force in the case of a Contact between the knife and the die through the the force acting on the knife is not exceeded.
- setting can be used to adapt to a specific Serve packaging material.
- the notch cutting device with Advantage is designed and controlled so that when it is executed a cut by moving the knife part towards one another and the die on the knife a force of at most 1000 N per mm knife length, preferably 10 - 100 N per mm of knife length and per mm of thickness to be cut Packaging material, acts. With these forces, the Knives do not wear out unnecessarily quickly. To be a good one Making a cut, on the other hand, generally becomes dependent from the packaging material, a separation force of at least 10 N per mm knife length and per mm material thickness required.
- the arrangements of the individual knives are advantageous in the knife part between a cutting position and one Notch position adjustable, with a knife in the cutting position when making a cut the between packing material arranged for the knife and the die completely cuts through while a knife is in the notch position that between the knife and the die Only cut packaging material. This makes possible changing the cutting configuration in a simple way.
- means for Supply and discharge of gas into and out of the gas cushion present that allow the dependency of the location of the knife against the tool plate on the force that acts on the knife.
- This setting can for example to adapt to a specific packaging material serve.
- At least one of the knives in the knife part thus retreating depending on the force arranged that there is a load that is smaller is as a limit force that maintains its position, and at a load that is greater than this limit force.
- each knife in the knife part on which the knife is in the notch position supports the execution of a cut directly or indirectly.
- the stop is preferably adjustable so that the depth of cut can be changed. With simple cutting The die and the knife become notches not brought into contact, so a force-dependent Arrangement of the knife usually brings no advantage.
- each knife in the knife part preferably adjustable, stop available on the the knife when making part of a cut, where a comparatively larger cutting force is required is directly or indirectly supported while it is in subsequent rest of the cut, in which a comparative smaller cutting force is required, spaced from it is.
- the knife is directly or indirectly supported at the stop. Falls below that on the Knife acting force again this certain value, e.g. at the end of the cutting process, the knife is replaced by the force-dependent arrangement in a closer to the die Position moves or it is moved completely to the die and the packaging material is completely separated.
- the illustrated first embodiment of an inventive Notch cutting device includes as a scaffold a table top 7 and a head plate 70, which by total four connecting columns 71, two of which are visible in FIG. 1 are connected.
- a tool plate 4 is attached, in turn a Stamp holding plate 31 is attached.
- a stamp holding plate 31 is attached on the tool plate 4 and the punch holding plate 31 .
- the directly and indirectly on the tool plate 4 arranged elements are part of the present description also referred to collectively as a knife part.
- the two guide columns 41 each protrude into a guide column channel 14 into the die base 13 and a die plate 11 mounted thereon is.
- the die plate 11 carries a die 1 and has together with this four stamp channels 12 into which the four punches 3 penetrate when making a cut.
- the die base 13, the die plate 11 and the die 1 by means of a piston 61 of a hydraulic Drive with hydraulic cylinder 6 vertically upwards moved so that the packaging material 9 between the die 1 and the knife part clamped and cut becomes.
- the knives 2 are each connected via two knife holders 21 to a piston 22, which is mounted in a gas chamber 23 formed in the tool plate 4 so as to be vertically displaceable.
- the gas chamber 23 On the piston side facing away from the plunger holding plate 31, the gas chamber 23 is filled with a gas, for example N 2 or compressed air, which is under a pressure of up to 300 bar.
- An annular seal 26 prevents gas from escaping from the gas chamber 23 between the chamber wall and the piston 22.
- the gas cushion present in the gas chamber 23 forms a compressible mass which, when the pressure on the knife 2 is sufficiently high and thus on the knife holder 21 is compressed onto the piston 22, so that the piston 22 and the knife 2 can move upward.
- Gas can be withdrawn or supplied to the gas chamber 23 via a gas channel 24, as a result of which the pressure or a limiting force can be set. If a smaller force than the limit force acts on the knife 2, this maintains its position relative to the tool plate 4; if a force acts greater than the limit force, it will recede.
- the pressure is preferably set such that a force of typically 10-100 N per mm knife length and per mm thickness of the packaging material, but at most 1000 N per mm knife length, acts on the knife 2 during the cutting.
- the stop 25 serves as an indirect support for the knife 2 in the so-called notch position. Namely, the packaging material 9 not completely cut, but only cut or notched, the knife 2 at the Make a cut at the slightest pressure give way to what by lowering the gas pressure in the gas chamber 23 achieved by withdrawing gas via the gas channel 24 can be. That makes a difference when making a cut Knife 2 upwards until piston 22 stops 25 is applied.
- the stop 25 By vertically adjusting the stop 25, here the notch depth can be increased by screwing it in or out can be set in packaging material 9.
- the punches 3 are firmly screwed to the tool plate 4 and held by the stamp holding plate 31. at When making a cut, they punch star-shaped holes into the packaging material 9 and penetrate the stamp channels 12 in the die 1.
- the wipers 5 stored in the tool plate 4 via compression springs 51.
- the Wipers 5 are first when making a cut pressed into the tool plate 4 by the die 1, the compression springs 51 are compressed. Becomes then pulled the die 1 down again, relax the compression springs 51 and push the wipers 5 and the latter the packaging material 9 down.
- Fig. 5 shows the notch cutting device when cutting Packaging material 9 in the form of yoghurt cups to the Time when the die 1 and the knife part their lowest Distance from each other. That is in the Left knife 2 in the cutting position has the packaging material 9 completely severed and touched the Die 1 while the notch is in position right knife 2 only cut the packaging material 9 or has notched.
- the cutting position of the left knife 2 results from that from a compressed gas supply 8 via a pressure reducer 81, a left switching valve 82 and the left gas channel 24 the gas chamber 23 is pressurized with compressed gas, that exerts a force on the left piston 22 that is greater is the cutting force used for cutting.
- the needed The separation force depends on the packaging material to be cut 9, but is usually at least 10 N per mm knife length and per mm thickness of packaging material. It can be seen that the left piston 22 is in the in Fig. 5 position shown with respect to that shown in Fig. 4 Basic position shifted up a bit has, the knife 2 is thus pushed up from the die 1 under compression of the gas chamber 23 existing compressed gas.
- This second embodiment of an inventive Notch cutting device largely corresponds to the first. in the However, there is no difference on the tool plate 104 adjustable stops 25 projecting into the gas chambers 123 available. Instead, the gas channels 124 are each central arranged above the gas chambers 123. Such a trained notch cutting device is particularly then an advantage if a knife 2 is sometimes switched off must so that it no longer cuts at all.
