Definitions
- the invention relates to cutting machines in which slices are to be cut from a strand-shaped or loaf-shaped material to be cut.
- the material to be cut is often guided in a guide tube, with the portion of the material to be cut protruding from the front of the guide tube on the cutting side being cut off as a disc by a rotating knife, for example, directly on the cutting-side end face of the guide tube.
- this guide tube can only consist of an axially very short so-called cutting goggle, which partially or completely surrounds that end of the material to be cut from which the slices are to be separated and the knife moves along its end face. In the following, however, only one guide tube is used throughout.
- the present application also includes solutions in which a single knife of two or more loaves guided in adjacent guide tubes simultaneously separates one slice, and / or solutions in which the guide tube is part of one around its central axis rotatable guide tube turret, around which a plurality of guide tubes are arranged.
- the knife should always cut through the material to be cut at the same, precisely defined axial distance, in particular the distance zero, to the end face of the guide tube, because this is the only way to produce slices with a defined thickness and thus also with a defined weight.
- the rotating knife for example, is supported on the side of the guide tube by the guide tube itself, on the opposite side a support that requires axial installation space - be it due to the correspondingly large thickness of the knife itself or an additional support device there - is necessary, but disadvantageous because this makes it more difficult for the knife to penetrate the material to be cut.
- an optimally thin knife would be the best solution, as it penetrates the material to be cut the easiest, but such a knife often does not have sufficient dimensional stability and, above all, insufficient positional stability, namely close to the end face of the guide tube.
- the uneven cross-section of the meat loaf is expanded to the uniform cross-section of the guide tube, so that the material to be cut has a uniform cross-section in the form of a strand or caliber, but this also causes the material to be cut under a There is increased pressure and that outside the guide tube there should be a longitudinal stop for the end of the material to be sliced that is pushed out of the guide tube.
- the knife Since the knife is not guided in a cutting gap on both sides, but only slides on one side along the end face of the guide tube, without additional measures there is a great risk that the knife will not be tight, in particular contacting, due to deformation, the irregular resistance of the material to be cut or other effects the end face of the guide tube slides along, but at a small distance therefrom, which undesirably changes the thickness and thus the weight of the disc produced.
- edge of the pane is usually frayed, which is undesirable for optical reasons.
- a grown piece of meat is surrounded by a so-called silver skin, a tendon-like material that is difficult to cut.
- a clean cutting instead of tearing through this silver skin is only possible if the cutting edge of the knife rests against the end face of the guide turret or form turret, especially when the knife emerges from the material to be cut, i.e. the guide tube cross-section.
- the knife In a cutting machine of the generic type , in which the knife is held on the end face of the guide tube by means of holding magnets, it is irrelevant whether the knife is a bar-shaped knife, a rotating circular disk-shaped knife or a rotating sickle-shaped knife or the knife of a band saw.
- the holding magnet (s) are arranged in the penetration direction only near the exit side of the guide tube cross section and outside the guide tube cross section, and not near the entry side.
- the direction of penetration is understood to mean the perpendicular to the knife edge which lies in the knife plane defined by the knife edge and / or the main plane of the knife. If the knife edge is curved, the perpendicular starts at the middle of the length of the knife edge.
- the knife is only subjected to magnetic force in the last part of the passage section of its knife edge through the material to be cut, i.e. through the guide tube cross-section, in the direction of the end face of the guide tube and thereby usually also brought into contact with the end face.
- this offers the advantage that before the magnetic force acts on the knife, i.e. in the first part of the passage of the cutting edge along the penetration path, there is no application of magnetic force to the knife in the direction of the end face of the guide tube and the knife does not or only the end face contacted with a very low contact force, so that there is hardly any heating of the knife and guide tube and hardly any increase in the cutting force to be applied.
- the holding magnet or magnets are only arranged in the last third of the penetration path of the knife edge in the penetration direction.
- the at least one holding magnet is arranged as close as possible to the outer circumference of the guide tube cross-section in order to apply magnetic force to the knife in the area of the guide tube cross-section in the direction of the end face.
- the holding magnet is preferably arranged transversely to the penetration direction, i.e. in the radial direction of the guide tube cross section, closer than 30 mm, better closer than 20 mm, better closer than 10 mm to the circumference of the guide tube cross section.
- the one or more holding magnets are arranged so close to the longitudinal position of the front, cutting-side face that the tensile force of the holding magnet on the knife at the longitudinal position of the cutting-side face still reaches or exceeds a predetermined minimum tensile force.
- the longitudinal position of the holding magnet is preferably adjustable for this purpose.
- the minimum tensile force of the individual magnets mounted in the machine at the longitudinal position of the cutting-side face should be at least between 100 N and 10 N, better between 70 N and 20 N, better between 50 N and 30 N, especially in relation to the knife used -Material.
- the sum of the minimum tensile forces of all holding magnets present on a guide tube should be between 400 N and 40 N, better between 280 N and 160 N, better between 200 N and 120 N, especially compared to the knife material used. All holding magnets present on a guide tube should in particular be those holding magnets which, when a pane protruding from this guide gate is cut off, at most all of them act together on the cutting knife.
- So-called knife steel is preferably used as the material for the knife, which is usually defined in such a way that its grade number starts with 1.40 - 1.46, preferably 1.40.
- the nickel content should be a maximum of 2.5% by weight and the carbon content a maximum of 1.2% by weight, while the chromium content should be at least 10.5% by weight, better still 13-15% by weight. If molybdenum is contained, its proportion should not be higher than 1.0% by weight.
- the counter number following in the type number is preferably between 16 and 34 and is preferably 21.
- the subsequent last two digits of the type number for the steel production process and the treatment state are preferably 3 for the steel production process and / or 4 for the treatment state.
- a steel of the grade number 1.4021.34 is therefore preferably used as the knife steel.
- the steel used for the knife must of course be able to be acted upon by magnetic force, i.e. it must be a soft magnetic material.
- the knife is preferably positioned with respect to the end face of the guide tube in the axial direction in such a way that the one facing the guide tube On the side of the knife without application of magnetic force, a narrow cutting gap of no more than 0.5 mm, better no more than 0.3 mm, better no more than 0.2 mm to the guide tube.
- the knife In order to pull the knife by means of the magnetic force of the at least one holding magnet until it makes contact with the end face - if the knife does not contact the end face without being applied by magnetic force - the knife should have a thickness of at most 10 mm, in particular at most 8 mm, in particular at most 6 mm, in particular have a maximum of 4 mm, in particular a maximum of 3 mm.
- the knife should have an extension of at least 10 mm, in particular at least 30 mm, in particular at least 50 mm, in the penetration direction.
- the extent from the cutting edge to the bearing block in which the knife is mounted is to be measured.
- the knife consists of a soft magnetic material, that is, a material on which a force can be exerted by means of a magnet.
- the knife is preferably made of stainless steel, that is to say a mostly high-alloy steel which does not rust under the conditions of use of such a cutting machine, but which at the same time has soft magnetic properties.
- the knife is preferably a knife that is only sharpened on one side, the sharpened side preferably being on the side of the knife facing away from the guide tube. Therefore, regardless of the exact dimensions of the knife, that is, its regrinding state, no changes to the positioning of the magnets, in particular in the axial direction, have to be made.
- the base frame of the cutting machine is stored.
- the guide tube openings 1.1-1.5 are used to receive a loaf 100 to be cut into slices, which in the initial state has a has an elongated but irregular shape, so that, corresponding to the cross-section of the loaf 100 in the initial state, it can optionally be introduced into a guide tube opening 1.1-1.5 with the best cross-section from above, from the loading end 1b, which of course does not apply to this the cutting position 12 may be, since there the longitudinal press drive 6 prevents the insertion from above.
- That angular position or angular segment with respect to the axis of rotation 1 'of the guide tube turret 1 which is swept over by the knife in use is referred to as the cutting position 12.
- the cutting position 12 is the angular position at which the penetration direction 2 is located.
- a rotating, circular disk-shaped knife 3 is arranged, which is driven to rotate around a knife axis 3 ', which is preferably parallel to the switching axis 1', the axis of rotation of the Guide tube turret 1 is located.
- the rotating knife 3 can be moved back and forth in a 1st transverse direction 11.1 to the longitudinal direction 10, which corresponds to the direction of the indexing axis 1 'of the guide tube turret 1, radially to the guide tube opening in the cutting position 12, e.g. 1.1 to cut off slices 101 of the product to be cut 100.
- the severed disc 101 falls onto the discharge conveyor 8 arranged below and is moved by this, for example, in the direction of view of the Figure 1c transported away.
- FIG Figure 2c thus shows the state immediately before the severed disc 101 fell onto the discharge conveyor 8, while in FIG Figure 1c the disk 101 is already on the discharge conveyor 8.
- the knife axis 3 ′ can also perform an arcuate, oscillating, or circular movement in order to cut off one disc 101 at a time.
- a longitudinal pressing drive 6 is arranged above the guide tube turret 1 at the so-called cutting position 12, viewed in the direction of the indexing axis 1 'and lying within the circumference of the guide tube turret 1, on the base frame of the machine.
- the longitudinal press drive 6 consists of a working cylinder, preferably a hydraulic cylinder, the piston rod of which can be moved in the longitudinal direction 10 6a when the working medium is applied from the lower, open end of the cylinder 6b increasingly extends and with its front end a longitudinal ram 4.1, which fits into the cross-section 1.1 'of the guide tube opening 1.1 below, pushes it into it until it rests on the loaf 100 and this presses down in the longitudinal direction 10 against a stop.
- a working cylinder preferably a hydraulic cylinder
- the stop serves as a stop Figure 1d Stop plate 14 that is moved up to the lower end face of the guide tube opening 1.1 located in the cutting position 12 and held, preferably completely covering this guide tube opening 1.1 before the start of the cutting process.
- longitudinal press rams 4.1 - 4.5 are arranged in a circular manner around its axis of rotation 13 ', the cross sections of which correspond to one of the cross sections 1.1' - 1.5 'of the guide tube openings 1.1 - 1.5 and are thus arranged in the press ram turret 13 are that they fit exactly and preferably liquid-tight into one of the guide tube openings 1.1-1.5 when they are in the cutting position 12 above this matching guide tube opening.
- the ram turret 13 can be rotated about the likewise upright, parallel to the indexing axis 1 ', but offset in a transverse direction, the indexing axis 13' so that with a certain guide tube opening 1.1 at the cutting position the same cross section 4.1 ' having longitudinal ram 4.1 can be positioned over this guide tube opening 1.1 by rotating the press ram turret 13 accordingly.
- the coupling parts 9a located on the upper side of the longitudinal ram 4.1-4.5 lie on a circular path around the switching axis 13 'of the press ram turret 13. If the corresponding longitudinal ram 4.1 is in alignment and above the cutting position 12, exactly in the path of movement of the another, complementary coupling part 9b arranged at the front end of the piston rod 6a.
- the longitudinal press ram 4.1 moves against a ram stop 15 when it reaches the corresponding recess in the press ram turret 13 or in this recess, so that when the piston rod 6a is retracted further, the coupling 9 solves and automatically releases the corresponding longitudinal ram 4.1, which is now held again in the ram turret 13 in the recess provided for the longitudinal ram 4.1, for example magnetically or by suitable locking elements there.
- Switching axis 1 means that the guide tube turret 1 can be rotated, but can also be locked in certain angular positions so that it is possible to switch from one to the next of the defined angular positions.
- the 1st transverse direction 11.1 is always spoken of, without restricting the invention to this, although the direction of displacement 2 is also a different transverse to the longitudinal direction 10 of the guide tube turret 1 can be direction.
- the knife 3 is mounted rotatably about its knife axis 3 ′ on a slide 19, which can be moved in this direction of displacement 2 with respect to the cutting base frame 18.
- the stop plate 14 is also carried by the slide 19, but is adjustable with respect to it at least in the axial direction 10, possibly also in the radial direction.
- knife 3 and stop plate 14 move preferably synchronously in penetration direction 2, preferably 1st transverse direction 11.1, so that the resulting disc 101 is increasingly pushed through the gap between cutting edge 3a of knife 3 and the functional edge 14a of stop plate 14 facing the knife .
- the functional edge 14a is - in the axial direction 10, for example viewed from below - preferably concavely curved and runs in alignment or slightly radially outward in this viewing direction, in particular at a constant distance over the length of the functional edge, compared to the circular circumference of the cutting edge 3a .
- the stop plate 14 and thus its functional edge 14a can additionally according to FIG Figure 1a can be adjusted in the 1st transverse direction 11.1 with respect to the carriage 19 and thus the cutting edge 3a of the knife 3, preferably also during the cutting process.
- Figure 1d shows a state of the cutting machine in which two processes are shown at the same time, but in practice they do not have to occur simultaneously: On the one hand, the stop plate 14 is raised so far that it rests directly on the lower end face of the guide tube turret 1, the cutting end 1a, as may be necessary as a stop for the longitudinal pressing of the loaf 100 at the cutting position 12.
- the knife 3 is shifted so far away from the indexing axis 1 'of the guide tube turret 1 that, viewed in the longitudinal direction 10, it is completely outside the cross section of the guide tube turret 1, so that the knife 3, which is on its underside from the slide 19 is supported, is freely accessible from the top over its entire surface and can be removed upwards after loosening a quick-release fastener 20 and exchanged for another knife.
- the ones in the Figures 2a to 2c The ones in the Figures 2a to 2c
- the depressions 21 shown around the center of the knife 3, preferably on a circular path, as well as openings 22 through the disc-shaped knife 3 serve primarily to reduce the weight of the knife 3 and the openings 22 also serve as gripping openings for gripping the knife 3 when changing knives.
- holding magnets 7 are present, but in the penetration direction 2 only near the end of the penetration path 2 ':
- FIG. 2a using the example of the guide tube opening 1.2 shows - viewed in the longitudinal direction 10 - on the two sides of each shaped tube opening with respect to its penetration direction 2, here the radial direction with respect to the switching axis 1 'of the guide tube turret 1 through the center of the respective guide tube Opening, at least one holding magnet 7, usually at least two holding magnets 7 each, but only in the last third of the penetration distance 2 ', because the knife 3 should only be used there, so that the knife edge 3a rests against the end face 1a of the guide tube turret 1 with pretension at the exit end 2a of the penetration path 2 ′, which is located radially on the inside with respect to the guide tube turret 1.
- Figure 4 shows - again viewed in the longitudinal direction 10, usually the longitudinal pressing direction - the arrangement of the holding magnets 7 with two guide tube openings 1.1, 1.2 running parallel next to one another, which additionally in a 1st transverse direction to the longitudinal direction 10 by means of a transverse pressing of the loaf inserted therein of a cross press ram. Since in this case the penetration direction 2 often coincides with the transverse compression direction, the length of the penetration path 2 ', which the knife edge 3a has to cover through the cross section of the guide tube opening, also changes with the extent of the transverse compression.

Description
Die Erfindung betrifft Schneidemaschinen, bei denen von einem strangförmigen oder laibförmigen Schneidgut Scheiben abgeschnitten werden sollen.The invention relates to cutting machines in which slices are to be cut from a strand-shaped or loaf-shaped material to be cut.
Das Schneidgut ist dabei häufig in einem Führungsrohr geführt, wobei der aus dem Führungsrohr stirnseitig auf der Schneidseite vorstehende Anteil des Schneidgutes durch ein z.B. rotierendes Messer unmittelbar an der schneidseitigen Stirnfläche des Führungsrohres als Scheibe abgetrennt wird.The material to be cut is often guided in a guide tube, with the portion of the material to be cut protruding from the front of the guide tube on the cutting side being cut off as a disc by a rotating knife, for example, directly on the cutting-side end face of the guide tube.
An dieser Stelle soll klargestellt werden, dass dieses Führungsrohr auch nur aus einer axial sehr kurzen sogenannten Schneidbrille bestehen kann, die dasjenige Ende des Schneidgutes teilweise oder vollständig umgibt, von dem die Scheiben abgetrennt werden sollen, und an dessen Stirnfläche sich das Messer entlang bewegt. Im Folgenden wird dennoch durchgängig nur von einem Führungsrohr gesprochen.At this point it should be made clear that this guide tube can only consist of an axially very short so-called cutting goggle, which partially or completely surrounds that end of the material to be cut from which the slices are to be separated and the knife moves along its end face. In the following, however, only one guide tube is used throughout.
Es soll ferner klargestellt werden, dass die vorliegende Anmeldung auch Lösungen umfasst, bei der ein einziges Messer von zwei oder mehr in nebeneinanderliegenden Führungsrohren geführten Laiben gleichzeitig je eine Scheibe abtrennt, und/oder auch Lösungen, bei denen das Führungsrohr Bestandteil eines um seine zentrale Achse drehbaren Führungsrohr-Revolvers ist, um die herum mehrere Führungsrohre angeordnet sind.It should also be made clear that the present application also includes solutions in which a single knife of two or more loaves guided in adjacent guide tubes simultaneously separates one slice, and / or solutions in which the guide tube is part of one around its central axis rotatable guide tube turret, around which a plurality of guide tubes are arranged.
Dabei soll das Messer das Schneidgut an immer dem gleichen, exakt festgelegten axialen Abstand, insbesondere dem Abstand Null, zur Stirnseite des Führungsrohres durchtrennen, denn nur so können Scheiben mit einer definierten Dicke und damit auch mit einem definierten Gewicht erzeugen werden.The knife should always cut through the material to be cut at the same, precisely defined axial distance, in particular the distance zero, to the end face of the guide tube, because this is the only way to produce slices with a defined thickness and thus also with a defined weight.
Das z.B. rotierende Messer wird dabei auf der Seite des Führungsrohres vom Führungsrohr selbst abgestützt, auf der Gegenseite ist eine Abstützung, die ja axialen Bauraum erfordert - sei es durch entsprechend große Dicke des Messers selbst oder eine zusätzliche dortige Abstützvorrichtung - notwendig, aber nachteilig, weil dadurch das Eindringen des Messers in das Schneidgut erschwert wird.The rotating knife, for example, is supported on the side of the guide tube by the guide tube itself, on the opposite side a support that requires axial installation space - be it due to the correspondingly large thickness of the knife itself or an additional support device there - is necessary, but disadvantageous because this makes it more difficult for the knife to penetrate the material to be cut.
Theoretisch wäre ein optimal dünnes Messer die beste Lösung, da es am leichtesten in das Schneidgut eindringt, jedoch weist ein solches Messer häufig nicht die ausreichende Formstabilität und vor allem nicht die ausreichende Lagestabilität, nämlich dicht anliegend an der Stirnfläche des Führungsrohres, auf.Theoretically, an optimally thin knife would be the best solution, as it penetrates the material to be cut the easiest, but such a knife often does not have sufficient dimensional stability and, above all, insufficient positional stability, namely close to the end face of the guide tube.
Dieses Problem ist bei einem Schneidgut mit gleichmäßiger Konsistenz und geringem Schneidwiderstand wie etwa Wurst oder Käse - welches in der Regel auch einen in axialer Richtung durchgängig gleichen Querschnitt besitzt und somit strangförmig ist - noch nicht so akut wie bei einem unregelmäßig strukturierten und geformten Laib eines Schneidgutes wie etwa einem Stück Frischfleisch, welcher dann zusätzlich im Führungsrohr als Formrohr noch in Längsrichtung und/oder Querrichtung vor dem Aufschneiden vorverpresst werden kann.This problem is not yet as acute in the case of items to be sliced with a uniform consistency and low cutting resistance such as sausage or cheese - which generally also has the same cross-section in the axial direction and is therefore strand-shaped - as it is with an irregularly structured and shaped loaf of items to be sliced such as a piece of fresh meat, which can then also be pre-pressed in the guide tube as a shaped tube in the longitudinal direction and / or transverse direction before slicing.
Dabei wird der ungleichmäßige Querschnitt des Fleischlaibes auf den gleichmäßigen Querschnitt des Führungsrohres ausgedehnt, so dass das Schneidgut einen gleichmäßigen Querschnitt in Form eines Stranges oder Kalibers aufweist, was aber auch bewirkt, dass das Schneidgut unter einem erhöhten Druck steht und das außerhalb des Führungsrohres ein Längsanschlag für das aus dem Führungsrohr heraus geschobenes Ende des Schneidgutes vorhanden sein sollte.The uneven cross-section of the meat loaf is expanded to the uniform cross-section of the guide tube, so that the material to be cut has a uniform cross-section in the form of a strand or caliber, but this also causes the material to be cut under a There is increased pressure and that outside the guide tube there should be a longitudinal stop for the end of the material to be sliced that is pushed out of the guide tube.
Da das Messer nicht beidseitig in einem Schneidspalt geführt wird, sondern nur einseitig an der Stirnfläche des Führungsrohres entlang gleitet, ist ohne Zusatzmaßnahme die Gefahr groß, dass das Messer durch Verformung, den unregelmäßigen Widerstand des Schneidgutes oder andere Effekte nicht eng, insbesondere kontaktierend, an der Stirnfläche des Führungsrohres entlang gleitet, sondern in einem geringen Abstand hierzu, was die Dicke und damit das Gewicht der erzeugten Scheibe unerwünschtermaßen verändert.Since the knife is not guided in a cutting gap on both sides, but only slides on one side along the end face of the guide tube, without additional measures there is a great risk that the knife will not be tight, in particular contacting, due to deformation, the irregular resistance of the material to be cut or other effects the end face of the guide tube slides along, but at a small distance therefrom, which undesirably changes the thickness and thus the weight of the disc produced.
Vor allem aber bewirkt dies kein gutes Schneidergebnis an der Scheibe, welches nur erzielt wird, wenn die Schneidkante des Messers ohne Abstand und gegen eine Gegenschneide, in diesem Fall in Form des Innenumfanges der Führungsrohröffnung des Führungsrohres an der Austrittsseite des Führungsrohres entlang gleitet.Above all, however, this does not cause a good cutting result on the disc, which is only achieved if the cutting edge of the knife slides without clearance and against a counter blade, in this case in the form of the inner circumference of the guide tube opening of the guide tube on the outlet side of the guide tube.
Ist dies nicht der Fall, ist der Rand der Scheibe meistens ausgefranst, was aus optischen Gründen nicht erwünscht ist.If this is not the case, the edge of the pane is usually frayed, which is undesirable for optical reasons.
Ein gewachsenes Fleischstück ist von einer sogenannten Silberhaut, einem sehnenartigen, schwer zu durchtrennenden Material, umgeben. Ein sauberes Durchtrennen anstelle eines Durchreissens dieser Silberhaut ist nur möglich, wenn die Schneide des Messers dabei an der Stirnfläche des Führungsrevolvers bzw. Formrevolvers anliegt, vor allem beim Austritt des Messers aus dem Schneidgut, also dem Führungsrohr-Querschnitt.A grown piece of meat is surrounded by a so-called silver skin, a tendon-like material that is difficult to cut. A clean cutting instead of tearing through this silver skin is only possible if the cutting edge of the knife rests against the end face of the guide turret or form turret, especially when the knife emerges from the material to be cut, i.e. the guide tube cross-section.
Aus der
Es hat sich jedoch gezeigt, dass dies zu einer verstärkten Reibung zwischen Messer und Führungsrohr führt, und damit einerseits zu einer Erwärmung dieser Bauteile und auch des darin aufgenommenen Schneidgutes sowie andererseits zu einem erhöhten Kraftaufwand zum Bewegen des Messers.It has been shown, however, that this leads to increased friction between the knife and the guide tube, and thus, on the one hand, to a heating of these components and also of the material to be sliced and, on the other hand, to an increased effort to move the knife.
Auch aus der
Es ist daher die Aufgabe gemäß der Erfindung, eine Vorrichtung und ein Verfahren zum Heranziehen des Messers an die schneidseitige Stirnfläche des Führungsrohres einer Schneidemaschine zur Verfügung zu stellen und dennoch die beschriebenen Nachteile zu vermeiden.It is therefore the object of the invention to provide a device and a method for pulling the knife to the cutting-side end face of the guide tube of a cutting machine and still avoid the disadvantages described.
Diese Aufgabe wird durch die Merkmale der Ansprüche 1 und 14 gelöst. Vorteilhafte Ausführungsformen ergeben sich aus den Unteransprüchen.This object is achieved by the features of
Bei einer gattungsgemäßen Schneidemaschine, bei der das Messer mittels Haltemagneten an der Stirnfläche des Führungsrohres gehalten wird, ist es unerheblich, ob es sich bei dem Messer um ein balkenförmiges Messer, ein rotierende kreisscheibenförmiges oder ein rotierendes sichelförmiges Messer oder um das Messer einer Bandsäge handelt.In a cutting machine of the generic type , in which the knife is held on the end face of the guide tube by means of holding magnets, it is irrelevant whether the knife is a bar-shaped knife, a rotating circular disk-shaped knife or a rotating sickle-shaped knife or the knife of a band saw.
Bei einer erfindungsgemäßen Schneidemaschine sind der oder die Haltemagnete in Eindringrichtung nur nahe der Austrittsseite des Führungsrohr-Querschnittes und außerhalb des Führungsrohr-Querschnittes angeordnet, und nicht nahe der Eintrittsseite.In the case of a cutting machine according to the invention , the holding magnet (s) are arranged in the penetration direction only near the exit side of the guide tube cross section and outside the guide tube cross section, and not near the entry side.
Unter Eindringrichtung wird die Lotrechte auf die Messerkante verstanden, die in der durch die Messerkante und/oder die Hauptebene des Messers definierte Messerebene liegt. Ist die Messerkante gekrümmt, setzt die lotrechte an der Mitte der Länge der Messerkante an.The direction of penetration is understood to mean the perpendicular to the knife edge which lies in the knife plane defined by the knife edge and / or the main plane of the knife. If the knife edge is curved, the perpendicular starts at the middle of the length of the knife edge.
Dadurch wird das Messer erst im letzten Teil der Durchlaufstecke seiner Messerkante durch das Schneidgut, also durch den Führungsrohr-Querschnitt, in Richtung der Stirnfläche des Führungsrohres mit Magnetkraft beaufschlagt und dadurch in der Regel auch in Kontakt mit der Stirnfläche gebracht.As a result, the knife is only subjected to magnetic force in the last part of the passage section of its knife edge through the material to be cut, i.e. through the guide tube cross-section, in the direction of the end face of the guide tube and thereby usually also brought into contact with the end face.
Dies bewirkt zum Einen, dass die Schneidkante des Messers gegenüber der Frontkante des Innenumfanges des Führungsrohr-Querschnittes als Gegenschneide abschert, was einen exakten Schnitt bewirkt, sodass auch die Silberhaut ohne Probleme sauber durchschnitten wird.On the one hand, this has the effect that the cutting edge of the knife shears off as a counter-blade opposite the front edge of the inner circumference of the guide tube cross-section, which causes an exact cut so that the silver skin is also cut cleanly without any problems.
Darüber hinaus bietet dies den Vorteil, dass vor dem Einwirken der Magnetkraft auf das Messer, also im ersten Teil des Durchlaufes der Schneidkante entlang der Eindringstrecke, noch keine Beaufschlagung des Messers mit Magnetkraft in Richtung Stirnfläche des Führungsrohres erfolgt und das Messer die Stirnfläche nicht oder nur mit einer sehr geringen Anlagekraft kontaktiert, so dass dabei kaum eine Erwärmung von Messer und Führungsrohr sowie kaum eine Erhöhung der aufzubringenden Schneidkraft eintritt.In addition, this offers the advantage that before the magnetic force acts on the knife, i.e. in the first part of the passage of the cutting edge along the penetration path, there is no application of magnetic force to the knife in the direction of the end face of the guide tube and the knife does not or only the end face contacted with a very low contact force, so that there is hardly any heating of the knife and guide tube and hardly any increase in the cutting force to be applied.
Insbesondere sind der oder die Haltemagnete nur im letzten Drittel der Eindringstrecke der Messerkante in Eindringrichtung angeordnet.In particular, the holding magnet or magnets are only arranged in the last third of the penetration path of the knife edge in the penetration direction.
Dabei ist der mindestens eine Haltemagnet so nahe wie möglich am äußeren Umfang des Führungsrohr-Querschnittes angeordnet, um das Messer gerade im Bereich des Führungsrohr-Querschnittes mit Magnetkraft in Richtung der Stirnfläche zu beaufschlagen.The at least one holding magnet is arranged as close as possible to the outer circumference of the guide tube cross-section in order to apply magnetic force to the knife in the area of the guide tube cross-section in the direction of the end face.
Vorzugsweise ist der Haltemagnet quer zur Eindringrichtung, also in radialer Richtung des Führungsrohr-Querschnittes, näher als 30 mm, besser näher als 20 mm, besser näher als 10 mm am Umfang des Führungsrohr-Querschnittes angeordnet.The holding magnet is preferably arranged transversely to the penetration direction, i.e. in the radial direction of the guide tube cross section, closer than 30 mm, better closer than 20 mm, better closer than 10 mm to the circumference of the guide tube cross section.
In axialer Richtung sind der eine oder die mehreren Haltemagnete so nahe an der Längsposition der vorderen, schneidseitigen Stirnfläche angeordnet, dass die Zugkraft des Haltemagneten an der Längsposition der schneidseitigen Stirnfläche auf das Messer noch eine vorgegebene Mindest-Zugkraft erreicht oder übersteigt.In the axial direction, the one or more holding magnets are arranged so close to the longitudinal position of the front, cutting-side face that the tensile force of the holding magnet on the knife at the longitudinal position of the cutting-side face still reaches or exceeds a predetermined minimum tensile force.
Vorzugsweise ist die Längsposition des Haltemagneten hierfür einstellbar.The longitudinal position of the holding magnet is preferably adjustable for this purpose.
Die Mindest-Zugkraft des einzelnen, in der Maschine montierten, Magneten an der Längsposition der schneidseitigen Stirnfläche sollte mindestens zwischen 100 N und 10 N, besser zwischen 70 N und 20 N, besser zwischen 50 N und 30 N betragen, insbesondere gegenüber dem verwendeten Messer-Werkstoff.The minimum tensile force of the individual magnets mounted in the machine at the longitudinal position of the cutting-side face should be at least between 100 N and 10 N, better between 70 N and 20 N, better between 50 N and 30 N, especially in relation to the knife used -Material.
Die Summe der Mindest-Zugkräfte aller an einem Führungsrohr vorhandenen Haltemagnete sollte zwischen 400 N und 40 N, besser zwischen 280 N und 160 N, besser zwischen 200 N und 120 N, betragen, insbesondere gegenüber dem verwendeten Messer-Werkstoff. Alle an einem Führungsrohr vorhandenen Haltemagnete sollen insbesondere diejenigen Haltemagnete sein, die beim Abtrennen einer Scheibe, die aus diesem Führungstor vorsteht, maximal alle gemeinsam auf das abtrennende Messer einwirken.The sum of the minimum tensile forces of all holding magnets present on a guide tube should be between 400 N and 40 N, better between 280 N and 160 N, better between 200 N and 120 N, especially compared to the knife material used. All holding magnets present on a guide tube should in particular be those holding magnets which, when a pane protruding from this guide gate is cut off, at most all of them act together on the cutting knife.
Erst dann ist eine sichere Kontaktierung der Messerkante gegenüber der Stirnfläche ab dem Beaufschlagen des Messers mittels Magnetkraft sichergestellt.Only then is reliable contacting of the knife edge with respect to the end face ensured from the application of the knife by means of magnetic force.
Als Werkstoff für das Messer wird vorzugsweise so genannter Messerstahl verwendet, der in der Regel so definiert ist, dass dessen Sortennummer mit 1.40 - 1.46 beginnt, vorzugsweise mit 1.40.So-called knife steel is preferably used as the material for the knife, which is usually defined in such a way that its grade number starts with 1.40 - 1.46, preferably 1.40.
Insbesondere sollte der Nickelgehalt maximal 2,5 Gewichts-% betragen und der Kohlenstoffgehalt maximal 1,2 Gewichts-%, während der Chromgehalt mindestens 10,5 Gewicht-%, besser 13 - 15 Gewichts-%, betragen sollte. Falls Molybdän enthalten ist, sollte dessen Anteil nicht höher als 1,0 Gewichts-% betragen.In particular, the nickel content should be a maximum of 2.5% by weight and the carbon content a maximum of 1.2% by weight, while the chromium content should be at least 10.5% by weight, better still 13-15% by weight. If molybdenum is contained, its proportion should not be higher than 1.0% by weight.
Dadurch sind solche Messerstähle nichtrostend und noch härtbar, wobei meist Härten von 50 - 60 HRC angestrebt werden.As a result, such knife steels are rustproof and can still be hardened, with hardnesses of 50 - 60 HRC usually being aimed for.
Die in der Sortennummer danach folgende Zähler-Nummer bewegt sich vorzugsweise zwischen 16 und 34 und beträgt vorzugsweise 21.The counter number following in the type number is preferably between 16 and 34 and is preferably 21.
Die danach folgenden letzten beiden Ziffern der Sortennummer für das Stahlgewinnungsverfahren und den Behandlungszustand betragen vorzugsweise 3 für das Stahlgewinnungsverfahren und/oder 4 für den Behandlungszustand.The subsequent last two digits of the type number for the steel production process and the treatment state are preferably 3 for the steel production process and / or 4 for the treatment state.
Vorzugsweise wird somit als Messerstahl ein Stahl der Sortennummer 1.4021.34 verwendet.A steel of the grade number 1.4021.34 is therefore preferably used as the knife steel.
Der für das Messer verwendete Stahl muss natürlich mittels Magnetkraft beaufschlagbar sein, also ein weichmagnetischer Werkstoff sein.The steel used for the knife must of course be able to be acted upon by magnetic force, i.e. it must be a soft magnetic material.
Vorzugsweise ist das Messer gegenüber der Stirnfläche des Führungsrohres in axialer Richtung so positioniert, dass die dem Führungsrohr zugewandte Seite des Messers ohne Beaufschlagung mit Magnetkraft einen schmalen Schneidspalt von höchstens 0,5 mm, besser höchstens 0,3 mm, besser höchstens 0,2 mm zum Führungsrohr einnimmt.The knife is preferably positioned with respect to the end face of the guide tube in the axial direction in such a way that the one facing the guide tube On the side of the knife without application of magnetic force, a narrow cutting gap of no more than 0.5 mm, better no more than 0.3 mm, better no more than 0.2 mm to the guide tube.
Um das Messer mittels der Magnetkraft des mindestens einen Haltemagneten bis zur Kontaktierung an die Stirnfläche heranzuziehen - falls das Messer die Stirnfläche ohne Beaufschlagung durch Magnetkraft nicht kontaktiert - sollte das Messer eine Dicke von höchstens 10 mm, insbesondere höchstens 8 mm, insbesondere höchstens 6 mm, insbesondere höchstens 4 mm, insbesondere höchstens 3 mm besitzen.In order to pull the knife by means of the magnetic force of the at least one holding magnet until it makes contact with the end face - if the knife does not contact the end face without being applied by magnetic force - the knife should have a thickness of at most 10 mm, in particular at most 8 mm, in particular at most 6 mm, in particular have a maximum of 4 mm, in particular a maximum of 3 mm.
Aus dem gleichen Grund sollte das Messer in Eindringrichtung eine Erstreckung von mindestens 10 mm, insbesondere mindestens 30 mm, insbesondere mindestens 50 mm besitzen. Bei einem kreisscheibenförmigen, rotierenden Messer ist die Erstreckung von der Schneidkante bis zum Lagerbock, in dem das Messer gelagert ist, zu messen.For the same reason, the knife should have an extension of at least 10 mm, in particular at least 30 mm, in particular at least 50 mm, in the penetration direction. In the case of a circular disk-shaped rotating knife, the extent from the cutting edge to the bearing block in which the knife is mounted is to be measured.
Das Messer besteht ohnehin in aller Regel aus einem weichmagnetischen Material, also einem Material, auf welches mittels eines Magneten eine Kraft ausgeübt werden kann. Vorzugsweise besteht das Messer aus hygienischen Gründen aus Edelstahl, also einem unter den Einsatzbedingungen einer solchen Schneidemaschine nicht rostenden, meist hoch legiertem Stahl, der aber gleichzeitig weichmagnetische Eigenschaften besitzt.As a rule, the knife consists of a soft magnetic material, that is, a material on which a force can be exerted by means of a magnet. For reasons of hygiene, the knife is preferably made of stainless steel, that is to say a mostly high-alloy steel which does not rust under the conditions of use of such a cutting machine, but which at the same time has soft magnetic properties.
Vorzugsweise handelt es sich bei dem Messer um ein nur einseitig angeschliffenes Messer, wobei sich die Anschliff-Seite vorzugsweise auf der vom Führungsrohr abgewandten Seite des Messers befindet. Daher müssen unabhängig von den exakten Abmessungen des Messers, also seinem Nachschleif-Zustand, keine Änderungen an der Positionierung der Magnete, insbesondere in axialer Richtung, vorgenommen werden.The knife is preferably a knife that is only sharpened on one side, the sharpened side preferably being on the side of the knife facing away from the guide tube. Therefore, regardless of the exact dimensions of the knife, that is, its regrinding state, no changes to the positioning of the magnets, in particular in the axial direction, have to be made.

Ein - in diesem Fall aufrecht stehender und vom Querschnitt her runder, insgesamt zylindrischer - Führungsrohr-Revolver 1 ist um eine Drehachse 1', die in diesem Fall ebenfalls aufrecht steht und die Symmetrieachse des zylindrischen Führungsrohr-Revolvers 1 darstellt - drehbar im - nicht dargestellten - Grundgestell der Schneidemaschine gelagert.The basic, generic structure of the cutting machine can best be seen in the synopsis of the

Über den Umfang verteilt befinden sich in dem Führungsrohr-Revolver 1 mehrere axial verlaufende Führungsrohr-Öffnungen 1.1 - 1.5 mit unterschiedlichem freiem innerem Querschnitt 1.1' - 1.5', die sowohl am vorderen, unteren Schneidende 1a als auch am oberen, hinteren Beladeende 1b münden, also stirnseitig jeweils offen sind.Distributed over the circumference in the

Der Pressstempel-Revolver 13 ist um die ebenfalls aufrechte, parallel zur Schaltachse 1' verlaufende, zu dieser jedoch in einer Querrichtung versetzte, Schaltachse 13' drehbar, sodass bei einer bestimmten, an der Schneidposition befindlichen Führungsrohr-Öffnung 1.1 der den gleichen Querschnitt 4.1' aufweisende Längs-Pressstempel 4.1 durch entsprechendes Drehen des Pressstempel-Revolvers 13 über dieser Führungsrohr-Öffnung 1.1 positioniert werden kann.The
Beim Annähern des unteren, freien Endes der Kolbenstange 6a gegen die Oberseite des in der Schneidposition 12 befindlichen, noch im Pressstempel-Revolver 13 gehaltenen, Längs-Pressstempels 4.1 werden diese automatisch miteinander verbunden mittels einer Kupplung 9, indem am unteren freien Ende der Kolbenstange 6a einerseits und/oder der Oberseite jedes der Längs-Pressstempel 4.1 - 4.5 andererseits entsprechende, zusammenwirkende Kupplungs-Teile 9a, b vorhanden sind.When the lower, free end of the
Die auf der Oberseite der Längs-Pressstempel 4.1 - 4.5 befindlichen Kupplungsteile 9a liegen auf einer Kreisbahn um die Schaltachse 13' des Pressstempel-Revolvers 13. Wenn sich der entsprechende Längs-Pressstempel 4.1 fluchtend und über der Schneidposition 12 befindet, genau im Bewegungsweg des am vorderen Ende der Kolbenstange 6a angeordneten anderen, komplementären Kupplung-Teiles 9b.The
Beim Zurückziehen der Kolbenstange 6a mit dem daran befindlichen Längs-Pressstempels 4.1 fährt der Längs-Pressstempel 4.1 beim Erreichen der entsprechenden Aussparung im Pressstempel-Revolver 13 gegen einen Stempelanschlag 15 an oder in dieser Aussparung, sodass bei weiterem Zurückziehen der Kolbenstange 6a sich die Kupplung 9 löst und den entsprechenden Längs-Pressstempel 4.1 automatisch freigibt, der nun wieder in dem Pressstempel-Revolver 13 in der für den Längs-Pressstempel 4.1 vorgesehenen Aussparung gehalten wird, sei es z.B. magnetisch oder durch dortige geeignete Rastelemente.When the
Indem der Längspress-Antrieb 6 nur über der Schneidposition 12 vorhanden ist, vereinfacht sich der Aufbau der Schneidemaschine.Since the
Schaltachse 1' bedeutet, dass der Führungsrohr-Revolver 1, gedreht werden kann, aber zusätzlich in bestimmten Winkelstellungen arretiert werden kann, sodass also von einer zur nächsten der definierten Winkelstellungen weitergeschaltet werden kann.Switching axis 1 'means that the
Im Folgenden wird anstelle von Verlagerungsrichtung 2 der Messerachse 3' immer von der 1. Querrichtung 11.1 gesprochen, ohne die Erfindung hierauf zu beschränken, obwohl die Verlagerungsrichtung 2 auch eine andere quer zur Längsrichtung 10 des Führungsrohr-Revolvers 1 verlaufende Richtung sein kann.In the following, instead of the direction of
Das Messer 3 ist drehbar um seine Messerachse 3' an einem Schlitten 19 gelagert, der in dieser Verlagerungsrichtung 2 gegenüber dem Schneid-Grundgestell 18 verfahrbar ist. Auch die Anschlagplatte 14 wird von dem Schlitten 19 getragen, ist diesem gegenüber jedoch zumindest in axialer Richtung 10 verstellbar, gegebenenfalls auch in radialer Richtung.The
Beim Schneidvorgang bewegen sich Messer 3 und Anschlagplatte 14 vorzugsweise synchron in der Eindringrichtung 2, vorzugsweise 1. Querrichtung 11.1, sodass die entstehende Scheibe 101 zunehmend durch den Spalt zwischen der Schneide 3a des Messers 3 und der dem Messer zugewandten Funktionskante 14a der Anschlagplatte 14 hindurchgeschoben wird.During the cutting process,
Die Funktionskante 14a ist - in axialer Richtung 10, also beispielsweise von unten betrachtet- vorzugsweise konkav gekrümmt und verläuft in dieser Blickrichtung fluchtend oder leicht radial nach außen versetzt, insbesondere in einem über die Länge der Funktionskante gleichbleibenden Abstand, gegenüber dem kreisförmigen Umfang der Schneide 3a.The
Vorzugsweise kann die Anschlagplatte 14 und damit deren Funktionskante 14a zusätzlich gemäß
Diese sowie alle anderen Bewegungen bewegter Teile der Schneidemaschine werden von einer nicht dargestellten Steuerung angesteuert.These and all other movements of moving parts of the cutting machine are controlled by a controller, not shown.
Zum Einen ist die Anschlagplatte 14 soweit hochgefahren, dass sie unmittelbar an der unteren Stirnfläche des Führungsrohr-Revolvers 1, dem Schneidende 1a, anliegt, wie es als Anschlag für das Längs-Verpressen des Laibes 100 an der Schneidposition 12 notwendig sein kann.
On the one hand, the
Des Weiteren ist das Messer 3 so weit von der Schaltachse 1' des Führungsrohr-Revolvers 1 weg verlagert, dass es sich betrachtet in Längsrichtung 10 vollständig außerhalb des Querschnittes des Führungsrohr-Revolvers 1 befindet, sodass das Messer 3, welches auf seiner Unterseite vom Schlitten 19 abgestützt wird, von der Oberseite her über seine gesamte Fläche frei zugänglich ist und nach Lösen eines Schnellverschluss 20 nach oben abgenommen und gegen ein anderes Messer ausgetauscht werden kann.Furthermore, the
