Definitions
- the invention relates to a face cutting machine, in particular for cutting leafy material, with a table for receiving the material to be cut and a cutting device which can be moved in a vertical plane to the table surface which receives the material and which can be moved in a frame of the machine has mounted knife bar and a knife attached to it, at least two adjustable devices being mounted at a distance from each other in the knife bar, for supporting the knife in the area of the knife back on the knife bar.
- Face cutting machines are known from the prior art in a wide variety of variants, for example according to EP-A-0056874.
- Face cutting machines of the type mentioned are known from practice.
- the knife is connected to the cutter bar by means of several fastening screws.
- the screws are screwed into the tapped holes of the knife and penetrate elongated holes in the cutter bar that extend vertically to the table surface.
- the knife can be positioned in the desired position relative to the knife bar depending on its degree of wear and thus its regrinding.
- it is customary to support the knife against the knife bar in addition to the fastening screws in at least two places. This is usually solved using adjusting screws or cams that are adjustable in the stroke direction of the knife and press against the back of the knife.
- the disadvantage here is that adjusting screws and cams dig into the soft back of the knife and the knife thus changes its position relative to the knife bar, with the consequence that damage to the knife during operation, for example due to the knife back breaking out, can occur or with an exact cut is no longer possible for the knife.
- the object of the invention is to develop a face-cutting machine of the type mentioned at the outset such that a position set between the knife and the knife bar is permanently maintained with simple structural means.
- the problem is solved in a face-cutting machine of the type mentioned at the outset in that the respective adjustable Device is supported by a pressure piece on the back of the knife, the pressure piece being hard at least in the contact area with the respective adjustable device.
- This hard pressure piece is a separate component, so that in order to prevent the adjustable device from digging into the back of the knife, it is not necessary to harden the entire knife made of metal. Rather, it is sufficient to design the pairing between the adjustable device and the pressure piece with the corresponding hardness; Such hardness of the materials is not necessary between the pressure piece and the back of the knife, since the surface pressure between these parts is relatively low.
- the adjustable devices used which are designed, for example, as cams or set screws, consist of hardened metal and the pressure piece in the contact area with the adjustable device is hard, preferably also consists of hardened metal.
- the adjustable devices and the pressure piece can be made of any materials provided that they have the corresponding hardness and are suitable to withstand a high surface pressure.
- the great hardness of the pressure piece allows the cutting knife to be constructed in two parts, namely consisting of a knife holder made of non-hardened metal connected to the knife bar and a knife plate connected to the knife holder and actually carrying out the cut through the material, which, for example, is accommodated in a recess of the knife holder and is soldered to it.
- hard material is only used where there are high forces or surface pressures. In the other areas, it is sufficient to use less expensive, unhardened material.
- a preferred design provides that the adjustable device used in each case has a cam.
- This is expediently connected to a support shaft arranged perpendicular to it and supported in the knife.
- the cam disc leaves thus twist relative to the cutter bar and, due to their curve design, causes a more or less strong change in position of the cutter relative to the cutter bar.
- the cam disc can have, for example, a circumferential surface section which extends essentially over a semicircle and can be brought into contact with the back of the knife, the axis of the support shaft being arranged at a distance from the center of the circle. This results in an eccentricity that allows a maximum feed movement to be carried out when the cam disc is rotated by approximately 180 °.
- the infeed movement of the cam can also take place over a larger swivel angle, for example by means of a spiral configuration of the cam, with a swivel angle of, for example, 300 °.
- the cam disc transmits the forces applied to it via the knife into the knife bar via the support shaft.
- the cam disc can thus in principle be pivotable relative to the support shaft, in which case it is to be fixed, for example by being connected to the cutter bar in its set position resting on the blade back.
- the cam disc is advantageously connected in a rotationally fixed manner to the support shaft, which in turn can be fixed axially by means of a clamping element in the direction of rotation.
- the cam disc can also be fixed by means of a friction lining arranged between the latter and the cutter bar. This can be provided in addition to the clamping element.
- the respective support shaft should penetrate a hole in the knife carrier and thus be rotatable and fixable by the operator of the cutting machine.
- the pressure piece does not form part of the knife, but is arranged freely between the back of the knife and the adjustable device.
- the pressure piece therefore always lies optimally on the back of the knife, even if it is warped or not positioned exactly for other reasons.
- the pressure piece is connected to a plate-shaped guide element which is arranged between the cam and the cutter bar and engages behind the support shaft.
- the guide element is thus fixed between the cam disc and the cutter bar, the rear grip of which causes it to be suspended in the supporting shaft when the cutter is removed.
- the guide element advantageously has an elongated hole, the support shaft passing through this elongated hole.
- a special development of the invention provides that a spacer is arranged between the pressure piece and the knife. This is used when the knife is worn so far that a maximum infeed movement of the adjustable devices is not sufficient to position the back of the knife at the required distance from the knife bar. A further infeed movement of the knife is thus possible in accordance with the strength of the spacer.
- the spacer is expediently connected to the knife, in particular screwed to the knife.
- the pressure pieces and / or the spacers are advantageously arranged only in the area of the knife where the pressure forces are to be transmitted.
- the pressure pieces and / or the spacers are advantageously cuboid.
- the knife bar In order to ensure that the knife is fastened to the knife bar depending on its different relative positions, the knife bar must be provided with several elongated holes that extend in the adjustment direction of the knife relative to the knife carrier, with each elongated hole being assigned at least one threaded hole in the knife, and a fastening screw for this elongated hole and penetrates the threaded hole.
- each elongated hole being assigned at least one threaded hole in the knife, and a fastening screw for this elongated hole and penetrates the threaded hole.
- the knife should have several threaded bores associated with each elongated hole, which are spaced from one another in relation to the longitudinal extent of the elongated hole. The length of the respective elongated hole can thus be kept relatively small, with the respective fastening screw being screwed into the threaded bore associated with the elongated hole in order to achieve the large adjustment path.
- the face cutting machine 1 shown in FIG. 1 has a stand 2 with a table 3 and a portal frame 4 each extending above the table.
- the table 3 serves to receive the material to be cut in a cuboid shape on the table surface 6, which extends perpendicular to the plane of the sheet.
- the material to be cut is in particular a stack of snow material formed from leaves. The good to be cut is not shown in the figure.
- Figure 1 illustrates the face cutting machine, seen from the operator side. Behind the portal frame 4, a feed saddle 7 is mounted in the table 3 for moving the material to be cut perpendicular to the plane of the sheet. The figure shows the individual rake-like approaches 8 of the feed saddle.
- a cutter bar 9 is mounted in the portal frame 4 and is essentially vertical, i.e. movable in the sheet plane.
- a knife 10, which is only visible in the lower region, is arranged behind the knife bar 9 and screwed to the knife bar 9. Screws, not shown in FIG. 1, penetrate a plurality of vertically oriented elongated holes 11 in the cutter bar 9 and corresponding threaded bores in the cutter 10 intended.
- the lower surface of the press bar 12 is illustrated by reference number 5, the cutting edge of the knife 10 by the line 13.
- the lower contour of the knife bar 9 and knife 10 is inclined to the table surface 6, since the knife bar 9 and the knife 10 are moved in the swinging cut and consequently only come to lie parallel to the table surface 6 in their bottom dead centers.
- FIG. 1 illustrates the cutter bar 9, the cutter 10 and the press beam 12 in their respective raised positions.
- FIG. 1 a data input keyboard 14, a screen 15, switch 16, control buttons 17, a foot lever 19 for the cut indication and side panels 18 are also illustrated.
- the face cutting machine has two devices 20 for knife adjustment and support arranged at a horizontal distance from one another in the area of the knife bar 9.
- One of these devices 20 is described in detail for two embodiments in the following FIGS. 2-5.
- FIGS. 1 illustrates in the area of two elongated holes 11 of the cutter bar 9, the connection of the knife 10 with the cutter bar 9.
- Each elongated hole 11 is penetrated by a fastening screw 21, illustrated only for its threaded section, which is inserted from the front through the elongated hole 11 and into a corresponding threaded hole of the knife 10 is screwed.
- the slot 11 oriented vertically to the table surface 6 allows the distance between the lower edge 13 of the knife and the table surface 6 to be changed when the knife bar 9 is in an unchangeable position.
- the device 20 for knife support and its adjustment is suitable for supporting the knife 10 in any position. For this purpose, as can be seen in FIGS.
- a cam disk 22 which has a circumferential surface section 23 which extends in a spiral and essentially over an angle of approximately 300 °.
- a support shaft 24 is connected non-rotatably to the cam disk 22 and penetrates a horizontally oriented through hole 25 in the cutter bar 9 in a radially free manner. The spiral runs about the pivot axis 26 of the support shaft 24.
- the support shaft 24 is fixedly connected to the cam plate 22 by forming the support shaft 24 with a square insert which penetrates a corresponding opening in the cam plate 22 to form a press fit.
- a cuboidal pressure piece 29 made of hardened metal is inserted between the cam plate 22 and the knife back 28.
- This is connected to a guide plate 31 by means of two screws 30. It extends in the vertical direction and receives the pressure piece 29 in the region of its lower end and is provided in its central region with an elongated hole 32 which extends in its longitudinal direction.
- the guide plate 31 is arranged between the cam plate 22 and the cutter bar 9, the support shaft 24 passing through the elongated hole 32 of the guide plate 31.
- the cam plate 22 and the pressure piece 29 are made of hardened steel around the surface pressure to be able to master due to the line contact between these parts. Because of the relatively low surface pressure between the pressure pieces 29 and the knife 10 in the area of the knife back 28, the knife 10 is formed in two parts. It consists in a known manner of a knife carrier 33 made of non-hardened steel, which has the knife back 28, and a knife plate 34, which carries out the actual cutting and is provided with the cutting edge 13, which is inserted into a recess of the knife carrier 33 and is brazed to the latter .
- the knife plate 34 is made of hardened steel.
- the knife 10 can be resharpened in accordance with the vertical extent of the knife plate 34, thus reducing its vertical dimension. Due to the design of the face cutting machine with the device for adjusting the knife support, the knife 10 can be supported in a defined manner until it is completely ground off by means of the two cam disks 22 arranged at a distance from one another.
- FIG. 2 illustrates the width dimension of a new knife 10 with the distance dimension x '.
- the knife 10 wears out, it is removed from the cutter bar 9, the respective pressure piece 29 being held captively in the cutter bar 9 by means of the guide plate 31 due to its oscillating suspension in the associated support shaft 24.
- the knife 10 After the knife 10 has been sharpened, it is loosely connected to the knife bar 9 by means of the fastening screws 21 and the two cam disks 22 are rotated and thus adjusted with respect to the pressure pieces 29 so that the cutting edge 13 of the knife 10 is slightly in at knife bar 9 located at the bottom dead center a cutting bar, not shown, penetrates into the table 3. In this position, the fastening screws 21 are tightened.
- the supporting action of the cam disks 22 is effective as long as the width of the cutting knife 10 does not fall below the dimension x.
- a cuboid spacer 35 made of non-hardened metal is screwed to the knife carrier 33 in the region of the knife back 28 by means of several screws 36.
- the figure shows that the distance between the pressure piece 29 and the knife 10 effective 35 the full stroke of the associated cam 22 is available again.
- the fastening screws 21 are positioned approximately in the area of the upper ends of the elongated holes 11, the maximum infeed movement of the cam disks 22 results in a position of the fastening screws 21 approximately in the middle of the elongated holes 11, as shown in FIG. 2 and with a maximum feed movement of the cam disks 22, using the spacer 35, a position of the fastening screws 21 in the region of the lower ends of the elongated holes 11.
- the length of the elongated holes 11 can be reduced if a plurality of threaded bores are provided in the knife 10 in the longitudinal extent of the respective elongated hole 11, so that 10 different threaded bores 21 can be used depending on the width of the knife.
- the length of the elongated hole 32 in the respective guide plate 31 is dimensioned such that the support shaft 24 can freely pass through the elongated hole 32 during the eccentric stroke.
- the cam plate 22 is shrunk onto the rear end of the support shaft 24.
- the support shaft 24 is passed through the bore 25 of the cutter bar 9 and can be fixed in the front area facing away from the associated cam plate 22 by means of a clamping plate 37.
- the clamping plate 37 has a recess 38 in the cutter bar 9 and is provided with a bore whose diameter is slightly larger than the outside diameter of the support shaft 24.
- Parallel to the axis 26, the clamping plate 37 is provided with a threaded hole 39 into which a screw 40 is screwed , whose shaft penetrates a blind hole 41 in the cutter bar 9.
- the clamping plate 37 tilts slightly and thus places the associated support shaft 24 both axially and in the direction of rotation firmly.

Abstract
Description
Die Erfindung betrifft eine Planschneidmaschine, insbesondere zum Schneiden von blättrigem Gut, mit einem Tisch zur Aufnahme des zu schneidenden Gutes und einer in einer vertikalen Ebene zur das Gut aufnehmenden Tischoberfläche verfahrbaren Schneideinrichtung, die einen in einem Rahmen der Maschine verfahrbar gelagerten Messerbalken sowie einen an diesem befestigtes Messer aufweist, wobei mindestens zwei verstellbaren Einrichtungen im Abstand zueinander im Messerbalken gelagert sind, zum Abstützen des Messers im Bereich des Messerrückens am Messerbalken.The invention relates to a face cutting machine, in particular for cutting leafy material, with a table for receiving the material to be cut and a cutting device which can be moved in a vertical plane to the table surface which receives the material and which can be moved in a frame of the machine has mounted knife bar and a knife attached to it, at least two adjustable devices being mounted at a distance from each other in the knife bar, for supporting the knife in the area of the knife back on the knife bar.
Planschneidmaschinen sind aus dem Stand der Technik in den unterschiedlichsten Varianten bekannt, beispielsweise gemäß der EP-A-0056874.Face cutting machines are known from the prior art in a wide variety of variants, for example according to EP-A-0056874.
Planschneidmaschinen der eingangs genannten Art sind aus der Praxis bekannt. Bei diesen ist das Messer mittels mehrerer Befestigungsschrauben mit dem Messerbalken verbunden. Die Schrauben sind in Gewindebohrungen des Messers eingeschraubt und durchsetzen sich vertikal zur Tischoberfläche erstreckende Langlöcher im Messerbalken. Infolgedessen kann das Messer in Abhängigkeit von dessen Abnutzungsgrad und damit dessen Nachschliff in der gewünschten Position zum Messerbalken positioniert werden. Bei solchen Planschneidmaschinen mit Messerverstellung im Messerbalken ist es üblich, das Messer gegenüber dem Messerbalken, zusätzlich zu den Befestigungsschrauben, an mindestens zwei Stellen abzustützen. Dies wird üblicherweise über in Hubrichtung des Messers verstellbare Einstellschrauben oder Kurvenscheiben gelöst, die gegen den Messerrücken drücken. Nachteilig hierbei ist, daß sich Einstellschrauben und Kurvenscheiben in den weichen Messerrücken eingraben und das Messer damit seine Position gegenüber dem Messerbalken verändert, mit der Konsequenz, daß es im laufenden Betrieb zu Schädigungen des Messers, beispielsweise durch Ausbrechen des Messerrückens, kommen kann bzw. mit dem Messer kein exakter Schnitt mehr möglich ist.Face cutting machines of the type mentioned are known from practice. In these, the knife is connected to the cutter bar by means of several fastening screws. The screws are screwed into the tapped holes of the knife and penetrate elongated holes in the cutter bar that extend vertically to the table surface. As a result, the knife can be positioned in the desired position relative to the knife bar depending on its degree of wear and thus its regrinding. In such face-cutting machines with knife adjustment in the knife bar, it is customary to support the knife against the knife bar in addition to the fastening screws in at least two places. This is usually solved using adjusting screws or cams that are adjustable in the stroke direction of the knife and press against the back of the knife. The disadvantage here is that adjusting screws and cams dig into the soft back of the knife and the knife thus changes its position relative to the knife bar, with the consequence that damage to the knife during operation, for example due to the knife back breaking out, can occur or with an exact cut is no longer possible for the knife.
Aufgabe der Erfindung ist es, eine Planschneidmaschine der eingangs genannten Art so weiterzubilden, daß mit einfachen baulichen Mitteln eine zwischen dem Messer und dem Messerbalken eingestellte Position dauerhaft beibehalten wird.The object of the invention is to develop a face-cutting machine of the type mentioned at the outset such that a position set between the knife and the knife bar is permanently maintained with simple structural means.
Gelöst wird die Aufgabe bei einer Planschneidmaschine der eingangs genannten Art dadurch, daß sich die jeweilige verstellbare Einrichtung über ein Druckstück am Messerrücken abstützt, wobei das Druckstück zumindest im Kontaktbereich mit der jeweiligen verstellbaren Einrichtung hart ausgebildet ist. Dieses harte Druckstück stellt ein separates Bauteil dar, womit, um ein Eingraben der verstellbaren Einrichtung in den Messerrücken zu verhindern, es nicht erforderlich ist, das aus Metall bestehende Messer insgesamt zu härten. Es reicht vielmehr aus, die Paarung zwischen der verstellbaren Einrichtung und dem Druckstück mit der entsprechenden Härte auszugestalten; zwischen dem Druckstück und dem Messerrücken ist eine solche Härte der Materialien nicht erforderlich, da die Flächenpressung zwischen diesen Teilen relativ gering ist.The problem is solved in a face-cutting machine of the type mentioned at the outset in that the respective adjustable Device is supported by a pressure piece on the back of the knife, the pressure piece being hard at least in the contact area with the respective adjustable device. This hard pressure piece is a separate component, so that in order to prevent the adjustable device from digging into the back of the knife, it is not necessary to harden the entire knife made of metal. Rather, it is sufficient to design the pairing between the adjustable device and the pressure piece with the corresponding hardness; Such hardness of the materials is not necessary between the pressure piece and the back of the knife, since the surface pressure between these parts is relatively low.
Es reicht damit völlig aus, wenn die Verwendung findenden verstellbaren Einrichtungen, die beispielsweise als Kurvenscheibe oder Stellschraube ausgelegt sind, aus gehärtetem Metall bestehen und das Druckstück im Kontaktbereich mit der verstellbaren Einrichtung hart ist, vorzugsweise gleichfalls aus gehärtetem Metall besteht. Grundsätzlich können die verstellbaren Einrichtungen und das Druckstück aber aus beliebigen Materialien bestehen, sofern sie die entsprechende Härte aufweisen und geeignet sind, einer hohen Flächenpressung standzuhalten. Die große Härte des Druckstückes erlaubt es, das Schneidmesser zweiteilig auszubilden, nämlich bestehend aus einem mit dem Messerbalken verbundenen Messerträger aus nicht gehärtetem Metall und einer mit dem Messerträger verbundenen, den eigentlichem Schnitt durch das Gut vollführenden Messerplatte, die beispielsweise in einem Rücksprung des Messerträgers aufgenommen ist und mit diesem hart verlötet ist. Bei den vorbeschriebenen Materialpaarungen kommt damit hartes Material nur dort zum Einsatz, wo hohe Kräfte bzw. Flächenpressungen zu verzeichnen sind. In den anderen Bereichen reicht es aus, kostengünstigeres, ungehärtetes Material zu verwenden.It is therefore entirely sufficient if the adjustable devices used, which are designed, for example, as cams or set screws, consist of hardened metal and the pressure piece in the contact area with the adjustable device is hard, preferably also consists of hardened metal. In principle, however, the adjustable devices and the pressure piece can be made of any materials provided that they have the corresponding hardness and are suitable to withstand a high surface pressure. The great hardness of the pressure piece allows the cutting knife to be constructed in two parts, namely consisting of a knife holder made of non-hardened metal connected to the knife bar and a knife plate connected to the knife holder and actually carrying out the cut through the material, which, for example, is accommodated in a recess of the knife holder and is soldered to it. With the material combinations described above, hard material is only used where there are high forces or surface pressures. In the other areas, it is sufficient to use less expensive, unhardened material.
Eine bevorzugte Gestaltung sieht vor, daß die jeweils Verwendung findende verstellbare Einrichtung eine Kurvenscheibe aufweist. Diese ist zweckmäßig mit einer senkrecht zu ihr angeordneten, im Messer gelagerten Abstützwelle verbunden. Die Kurvenscheibe läßt sich damit relativ zum Messerbalken verdrehen und bedingt über deren Kurvengestaltung eine mehr oder weniger starke Positionsveränderung des Messers relativ zum Messerbalken. Die Kurvenscheibe kann beispielsweise einen sich im wesentlichen über einen Halbkreis erstreckenden, in Anlage mit dem Messerrücken bringbaren Umfangsflächenabschnitt aufweisen, wobei die Achse der Abstützwelle in Abstand zum Kreismittelpunkt angeordnet ist. Somit wird eine Exzentrizität bewirkt, die es gestattet, bei der Drehung der Kurvenscheibe um etwa 180° eine maximale Zustellbewegung zu vollführen. Die Zustellbewegung der Kurvenscheibe kann aber auch über einen größeren Schwenkwinkel erfolgen, beispielsweise mittels einer spiralförmigen Gestaltung der Kurvenscheibe, mit einem Schwenkwinkel von beispielsweise 300°. Grundsätzlich reicht es aus, wenn die Kurvenscheibe die über das Messer auf sie eingeleiteten Kräfte über die Abstützwelle in den Messerbalken überträgt. Die Kurvenscheibe kann damit grundsätzlich relativ zur Abstützwelle schwenkbar sein, wobei sie in diesem Fall festzulegen ist, beispielsweise indem sie in ihrer eingestellten, am Messerrücken anliegenden Position mit dem Messerbalken verbunden wird. Vorteilhaft ist die Kurvenscheibe aber drehfest mit der Abstützwelle verbunden, die ihrerseits mittels eines Klemmelementes in Drehrichtung und axial festlegbar ist. Alternativ kann die Kurvenscheibe auch mittels eines zwischen dieser und dem Messerbalken angeordneten Reibbelages festlegbar sein. Dieser kann zusätzlich zum Klemmelement vorgesehen sein.A preferred design provides that the adjustable device used in each case has a cam. This is expediently connected to a support shaft arranged perpendicular to it and supported in the knife. The cam disc leaves thus twist relative to the cutter bar and, due to their curve design, causes a more or less strong change in position of the cutter relative to the cutter bar. The cam disc can have, for example, a circumferential surface section which extends essentially over a semicircle and can be brought into contact with the back of the knife, the axis of the support shaft being arranged at a distance from the center of the circle. This results in an eccentricity that allows a maximum feed movement to be carried out when the cam disc is rotated by approximately 180 °. The infeed movement of the cam can also take place over a larger swivel angle, for example by means of a spiral configuration of the cam, with a swivel angle of, for example, 300 °. Basically, it is sufficient if the cam disc transmits the forces applied to it via the knife into the knife bar via the support shaft. The cam disc can thus in principle be pivotable relative to the support shaft, in which case it is to be fixed, for example by being connected to the cutter bar in its set position resting on the blade back. However, the cam disc is advantageously connected in a rotationally fixed manner to the support shaft, which in turn can be fixed axially by means of a clamping element in the direction of rotation. Alternatively, the cam disc can also be fixed by means of a friction lining arranged between the latter and the cutter bar. This can be provided in addition to the clamping element.
Um eine besonders einfache Bedienbarkeit der Einrichtung zu ermöglichen, sollte die jeweilige Abstützwelle eine Bohrung des Messerträgers durchsetzen und damit von der Bedienerseite der Schneidmaschine verdrehbar und festlegbar sein.In order to make the device particularly easy to operate, the respective support shaft should penetrate a hole in the knife carrier and thus be rotatable and fixable by the operator of the cutting machine.
Eine besondere Bedeutung wird darin gesehen, daß das Druckstück keinen Bestandteil des Messers bildet, sondern frei zwischen dem Messerrücken und der verstellbaren Einrichtung angeordnet ist. Das Druckstück liegt damit immer optimal am Messerrrücken an, auch dann, wenn er verzogen oder aus anderen Gründen nicht exakt positioniert sein sollte. In diesem Zusammenhang sieht eine besondere Ausführungsform der Erfindung vor, daß das Druckstück mit einem plattenförmigen Führungselement verbunden ist, das zwischen der Kurvenscheibe und dem Messerbalken angeordnet ist und die Abstützwelle hintergreift. Das Führungselement ist damit zwischen der Kurvenscheibe und dem Messerbalken fixiert, wobei dessen Hintergriff bewirkt, daß es bei entferntem Messer pendelnd in der Abstützwelle aufgehängt ist. Vorteilhaft weist das Führungselement ein Langloch auf, wobei die Abstützwelle dieses Langloch durchsetzt. Bei dieser Gestaltung des Führungselements ist damit das Druckstück zwischen der Kurvenscheibe und dem Messerbalken unverlierbar positioniert aber dennoch in Längsrichtung des Langloches entsprechend der Zustellbewegung der Kurvenscheibe verschieblich.A particular meaning is seen in the fact that the pressure piece does not form part of the knife, but is arranged freely between the back of the knife and the adjustable device. The pressure piece therefore always lies optimally on the back of the knife, even if it is warped or not positioned exactly for other reasons. In this context one sees Special embodiment of the invention that the pressure piece is connected to a plate-shaped guide element which is arranged between the cam and the cutter bar and engages behind the support shaft. The guide element is thus fixed between the cam disc and the cutter bar, the rear grip of which causes it to be suspended in the supporting shaft when the cutter is removed. The guide element advantageously has an elongated hole, the support shaft passing through this elongated hole. With this design of the guide element, the pressure piece between the cam disc and the cutter bar is thus captively positioned, but is nevertheless displaceable in the longitudinal direction of the elongated hole in accordance with the feed movement of the cam disc.
Eine besondere Weiterbildung der Erfindung sieht vor, daß zwischen dem Druckstück und dem Messer ein Distanzstück angeordnet ist. Dieses findet Verwendung, wenn das Messer soweit abgenutzt ist, daß eine maximale Zustellbewegung der verstellbaren Einrichtungen nicht ausreicht, dessen Messerrücken in erforderlichem Abstand zum Messerbalken zu positionieren. Eine weitere Zustellbewegung des Messers ist damit entsprechend der gewonnenen Stärke des Distanzstückes möglich. Das Distanzstück ist zweckmäßig mit dem Messer verbunden, insbesondere mit dem Messer verschraubt.A special development of the invention provides that a spacer is arranged between the pressure piece and the knife. This is used when the knife is worn so far that a maximum infeed movement of the adjustable devices is not sufficient to position the back of the knife at the required distance from the knife bar. A further infeed movement of the knife is thus possible in accordance with the strength of the spacer. The spacer is expediently connected to the knife, in particular screwed to the knife.
Vorteilhaft sind die Druckstücke und/oder die Distanzstücke nur in demjenigen Bereich des Messers angeordnet, wo die Druckkräfte zu übertragen sind. Die Druckstücke und/oder die Distanzstücke sind vorteilhaft quaderförmig ausgebildet.The pressure pieces and / or the spacers are advantageously arranged only in the area of the knife where the pressure forces are to be transmitted. The pressure pieces and / or the spacers are advantageously cuboid.
Um eine Befestigung des Messers am Messerbalken in Abhängigkeit von deren unterschiedlichen Relativpositionen sicherzustellen, ist der Messerbalken mit mehreren, sich in Verstellrichtung des Messers relativ zum Messerträger erstreckenden Langlöchern zu versehen, wobei jedem Langloch mindestens eine Gewindebohrung im Messer zugeordnet ist, sowie eine Befestigungsschraube dieses Langloch und die Gewindebohrung durchsetzt. Insbesondere für den Fall, daß zusätzlich ein Distanzstück Verwendung findet, womit sich ein großer Stellweg des Messers relativ zum Messerbalken ergibt, sollte das Messer jedem Langloch zugeordnet mehrere Gewindebohrungen aufweisen, die bezogen auf die Längserstreckung des Langloches in Abstand zueinander angeordnet sind. Es kann so die Länge des jeweiligen Langloches relativ klein gehalten werden, wobei, um den großen Stellweg zu erreichen, die jeweilige Befestigungsschraube in die den Langloch jeweils zugeordnete Gewindebohrung geschraubt wird.In order to ensure that the knife is fastened to the knife bar depending on its different relative positions, the knife bar must be provided with several elongated holes that extend in the adjustment direction of the knife relative to the knife carrier, with each elongated hole being assigned at least one threaded hole in the knife, and a fastening screw for this elongated hole and penetrates the threaded hole. Especially in the event that a spacer is additionally used, with which If the knife has a large travel distance relative to the knife bar, the knife should have several threaded bores associated with each elongated hole, which are spaced from one another in relation to the longitudinal extent of the elongated hole. The length of the respective elongated hole can thus be kept relatively small, with the respective fastening screw being screwed into the threaded bore associated with the elongated hole in order to achieve the large adjustment path.

Die in Figur 1 gezeigte Planschneidmaschine 1 weist einen Ständer 2 mit Tisch 3 sowie je einen sich oberhalb des Tisches erstreckenden Portalrahmen 4 auf. Der Tisch 3 dient der Aufnahme des in Quaderform vorliegenden zu schneidenden Gutes auf der Tischoberfläche 6, die sich senkrecht zur Blattebene erstreckt. Bei dem zu schneidenen Gut handelt es sich insbesondere um ein aus Blättern gebildeten Schneigutstapel. Das zu schneidende Gut ist in der Figur nicht gezeigt.The
Figur 1 veranschaulicht die Planschneidmaschine, von der Bedienerseite gesehen. Hinter dem Portalrahmen 4 ist im Tisch 3 ein Vorschubsattel 7 zum Verschieben des zu schneidenden Gutes senkrecht zur Blattebene gelagert. Verdeutlicht sind in der Figur die einzelnen rechenartigen Ansätze 8 des Vorschubsattels. Ein Messerbalken 9 ist im Portalrahmen 4 gelagert und im wesentlichen vertikal, d.h. in der Blattebene verfahrbar. Hinter dem Messerbalken 9 ist ein, nur im unteren Bereich sichtbares Messer 10 angeordnet und mit dem Messerbalken 9 verschraubt. In der Figur 1 nicht gezeigte Schrauben durchsetzen eine Vielzahl von vertikal orientierten Langlöchern 11 im Messerbalken 9 sowie mit diesen korrespondierende Gewindebohrungen im Messer 10. Hinter dem Messer 10 ist ein, nur im unteren Bereich sichtbarer Pressbalken 12 zum Niederdrücken des zu schneidenden Gutes während des Schnittes vorgesehen. Die untere Fläche des Pressbalkens 12 ist mit der Bezugsziffer 5 veranschaulicht, die Schneidkante des Messers 10 durch die Linie 13. In der Figur 1 verläuft die untere Kontur vom Messerbalken 9 und Messer 10 geneigt zur Tischoberfläche 6, da der Messerbalken 9 und das Messer 10 im Schwingschnitt bewegt werden und demzufolge nur in deren unteren Totpunkten parallel zur Tischoberfläche 6 zu liegen kommen. Die Figur 1 veranschaulicht den Messerbalken 9, das Messer 10 und den Pressbalken 12 in ihrer jeweils angehobenen Position.Figure 1 illustrates the face cutting machine, seen from the operator side. Behind the
In Figur 1 sind zusätzlich eine Dateneingabetastatur 14, ein Bildschirm 15, Schalter 16, Bedientasten 17, ein Fußhebel 19 für die Schnittandeutung sowie Seitenbleche 18 verdeutlicht.In Figure 1, a
Wie der Darstellung der Figur 1 zu entnehmen ist, weist die Planschneidmaschine im Bereich des Messerbalkens 9 zwei in horizontalem Abstand zueinander angeordnete Einrichtungen 20 zur Messerverstellung und -abstützung auf. Eine dieser Einrichtungen 20 ist im Detail für zwei Ausführungsformen in den nachfolgenden Figuren 2 - 5 beschrieben.As can be seen from the illustration in FIG. 1, the face cutting machine has two
Figur 2 verdeutlicht im Bereich zweier Langlöcher 11 des Messerbalkens 9 die Verbindung des Messers 10 mit dem Messerbalken 9. Jedes Langloch 11 wird von einer, nur für deren Gewindeabschnitt veranschaulichten Befestigungsschraube 21 durchsetzt, die von vorne durch das Langloch 11 hindurchgesteckt und in eine entsprechende Gewindebohrung des Messers 10 eingeschraubt ist. Das vertikal zur Tischoberfläche 6 orientierte Langloch 11 erlaubt es, bei unveränderlicher Position des Messerbalkens 9 den Abstand der Unterkante 13 des Messers zur Tischoberfläche 6 zu ändern. Die Einrichtung 20 zur Messerabstützung und deren Verstellung ist geeignet, das Messer 10 in beliebiger Stellung abzustützen. Hierzu ist, wie den Figuren 2 und 3 zu entnehmen ist, eine Kurvenscheibe 22 vorgesehen, die einen sich spiralförmig und im wesentlichen über einen Winkel von etwa 300° erstreckenden Umfangsflächenabschnitt 23 aufweist. Senkrecht zur Kurvenscheibe 22 ist eine Abstützwelle 24 mit dieser drehfest verbunden, die eine horizontal orientierte Durchgangsbohrung 25 im Messerbalken 9 radial spielfrei durchsetzt. Die Spirale läuft dabei um die Schwenkachse 26 der Abstützwelle 24. Fest verbunden ist die Abstützwelle 24 mit der Kurvenscheibe 22 durch Ausbildung der Abstützwelle 24 mit einem Vierkanteinsatz, der eine entsprechende Öffnung in der Kurvenscheibe 22 unter Bildung einer Presspassung durchsetzt.Figure 2 illustrates in the area of two
Zwischen die Kurvenscheibe 22 und dem Messerrücken 28 ist ein quaderförmiges Druckstück 29 aus gehärtetem Metall eingefügt. Dieses ist mittels zweier Schrauben 30 mit einer Führungsplatte 31 verbunden. Sie erstreckt sich in vertikaler Richtung und nimmt in dem Bereich ihres unteren Endes das Druckstück 29 auf und ist in ihrem zentralen Bereich mit einem sich in ihrer Längsrichtung erstreckenden Langloch 32 versehen. Die Führungsplatte 31 ist zwischen der Kurvenscheibe 22 und dem Messerbalken 9 angeordnet, wobei die Abstützwelle 24 das Langloch 32 der Führungsplatte 31 durchsetzt.A
Für den Bereich des Messers 10 der Planschneidmaschine 1 ergibt sich folgende Materialpaarung: Die Kurvenscheibe 22 und das Druckstück 29 bestehen aus gehärtetem Stahl, um die Flächenpressung infolge der Linienberührung zwischen diesen Teilen beherrschen zu können. Wegen der relativ niedrigen Flächenpressung zwischen den Druckstücken 29 und dem Messer 10 im Bereich des Messerrückens 28 ist das Messer 10 zweiteilig ausgebildet. Es besteht in bekannter Art und Weise aus einem Messerträger 33 aus nichtgehärtetem Stahl, der den Messerrücken 28 aufweist, sowie einer den eigentlichen Schnitt vollführenden, mit der Schneidkante 13 versehenen Messerplatte 34, die in einen Rücksprung des Messerträgers 33 eingesetzt und mit diesem hart verlötet ist. Die Messerplatte 34 besteht aus gehärtetem Stahl. Entsprechend der vertikalen Erstreckung der Messerplatte 34 kann das Messer 10 nachgeschliffen werden, womit sich dessen vertikale Abmessung reduziert. Auf Grund der Gestaltung der Planschneidmaschine mit der Einrichtung zum Verstellen der Messerabstützung kann das Messer 10 bis zu dessen vollständigen Abschliff definiert mittels der beiden in Abstand zueinander angeordneten Kurvenscheiben 22 abgestützt werden. Figur 2 verdeutlicht mit dem Abstandsmaß x' die Breitenerstreckung eines neuen Messers 10. Bei Einsatz eines neuen Messers 10 ist die Kurvenscheibe 22 in etwa 180° zu der in der Figur 2 dargestellten Position verdreht, und kontaktiert im Bereich ihres Umfangsflächenabschnittes 23 das Druckstück 29. Verschleißt das Messer 10, wird es vom Messerbalken 9 demontiert, wobei das jeweilige Druckstück 29 auf Grund dessen pendelnder Aufhängung in der zugeordneten Abstützwelle 24 mittels der Führungsplatte 31 verliersicher im Messerbalken 9 gehalten ist. Nach dem Schleifen des Messers 10 wird es mittels der Befestigungsschrauben 21 lose mit dem Messerbalken 9 verbunden und die beiden Kurvenscheiben 22 so verdreht und damit bezüglich der Druckstücke 29 so zugestellt, daß die Schneidkante 13 des Messers 10 bei im unteren Totpunkt befindlichen Messerbalken 9 geringfügig in eine in den Tisch 3 eingelassene, nicht gezeigte Schneidleiste eindringt. In dieser Position werden die Befestigungsschrauben 21 angezogen. Wie der Darstellung der Figur 2 zu entnehmen ist, ist die Stützwirkung der Kurvenscheiben 22 wirksam, solange die Breite des Schneidmessers 10 das Maß x nicht unterschreitet. Um auch bei einem auf dieses Maß abgeschliffenen Messers 10 dieses weiterverwenden zu können, wird gemäß der in Figur 4 dargestellten Ausführungsform ein quaderförmiges Distanzstück 35 aus nicht gehärtetem Metall mittels mehrerer Schrauben 36 mit dem Messerträger 33 im Bereich des Messerrückens 28 verschraubt. Die Figur verdeutlicht, daß bei zwischen dem Druckstück 29 und dem Messer 10 wirksamen Distanzstück 35 der volle Hub der zugeordneten Kurvenscheibe 22 erneut zur Verfügung steht. Während bei einem neuen Messer 10 die Befestigungsschrauben 21 annähernd im Bereich der oberen Enden der Langlöcher 11 positioniert sind, ergibt sich bei der maximalen Zustellbewegung der Kurvenscheiben 22, gemäß der Darstellung in Figur 2, eine Position der Befestigungsschrauben 21 etwa in der Mitte der Langlöcher 11 und bei einer maximalen Zustellbewegung der Kurvenscheiben 22 unter Verwendung des Distanzstückes 35 eine Position der Befestigungsschrauben 21 im Bereich der unteren Enden der Langlöcher 11.The following material pairing results for the area of the
Die Länge der Langlöcher 11 kann reduziert werden, wenn in Längserstreckung des jeweiligen Langloches 11 mehrere Gewindebohrungen im Messer 10 vorgesehen sind, so daß in Abhängigkeit von der Breitenerstreckung des Messers 10 unterschiedliche Gewindebohrungen 21 benutzt werden können. Die Länge des Langloches 32 in der jeweiligen Führungsplatte 31 ist so bemessen, daß die Abstützwelle 24 während des Exzenterhubes das Langloch 32 frei durchsetzen kann.The length of the
Bei der Ausführungsform nach der Figur 5 ist die Kurvenscheibe 22 auf das rückwärtige Ende der Abstützwelle 24 aufgeschrumpft. Die Abstützwelle 24 ist durch die Bohrung 25 des Messerbalkens 9 hindurchgeführt und in dem der zugeordneten Kurvenscheibe 22 abgewandten, vorderen Bereich mittels einer Klemmplatte 37 festlegbar. Die Klemmplatte 37 besitzt eine Aussparung 38 im Messerbalken 9 und ist mit einer Bohrung versehen, deren Durchmesser geringfügig größer iost als der Außendurchmesser der Abstützwelle 24. Paralell zur Achse 26 ist die Klemmplatte 37 mit einer Gewindebohrung 39 versehen, in die eine Schraube 40 eingeschraubt ist, deren Schaft ein Sackloch 41 im Messerbalken 9 durchsetzt. Beim Einschrauben der Schraube 40 in das Sackloch 41 kippt die Klemmplatte 37 geringfügig und legt die zugeordnete Abstützwelle 24 somit sowohl axial als auch in Drehrichtung fest. Um bei nicht geklemmeter Abstutzwelle 24 die zugeordnete Klemmplatte 37 verliersicher zu halten, ist das vordere Ende der Abstützwelle 24 mit einem Sicherungsring 42 versehen. Zum Drehen der jeweiligen Abstützwelle 24 und damit der zugeordneten Kurvenscheibe 22 ist die Abstützwelle 24 auf der Bedienerseite mit einer Innensechskantbohrung 43 zum Einsetzen eines Innensechskantschlüssels versehen.In the embodiment according to FIG. 5, the
