Definitions
- the invention relates to an adjusting device for pressing pressures exerted on the painting cylinder of a painting machine, in which the workpieces are moved between a painting cylinder with a jacket made of rubber or another elastic material and a hard impression cylinder, a first adjusting device for the pressing between the painting cylinder and the Counter-pressure cylinder is provided and a second adjusting device for pressing between the coating cylinder and a coating feed roller of a coating unit is provided.
- Such machines are used, for example, in the manufacture of beverage cans, glass lids or crown caps, where the printing is preceded by an internal coating and an external coating and a protective coating follows.
- There are special requirements for the paint provided so that it does not burst during later punching and deep drawing.
- previous painting machines poured paint over the workpieces
- modern painting machines aim to use paint as economically as possible.
- painting cylinders with precisely positioned cutouts are often used for recess painting.
- painting cylinders for full painting have the advantage that they can be reground many times and used for a correspondingly longer time.
- the change in the peripheral speed of the coating cylinder caused by the reduction in diameter must then be compensated for.
- a setting device of the type mentioned is already known from the market through its own manufacture.
- the painting cylinder for full painting is driven by a compressed air-operated slip clutch, which enables sensitive regulation of the peripheral speed during the run.
- This regulation requires operator participation.
- An electrical control device is installed for the recess painting, which monitors the rigidly coupled cylinder setting. Including uncoupling for setup purposes, a total of three operating states can be set with a switch lever.
- the setting of the coating cylinder and the coating feed roller, the switching on and off of all the rollers, their parallel position and the metering of the coating application are summarized centrally on the operating side of the machine, spindles provided with a handwheel being used.
- the coating cylinder and the coating feed roller can be fixed to the machine frame without play. However, this does not preclude locally uneven contact pressures, including possible operating errors, across the surface line of the painting cylinder with the high level of safety that has now been desired.
- the invention is based on the object of reliably avoiding irregularities in the pressing pressures exerted on the coating cylinder by simple means in a diameter range of the coating cylinder in the case of an adjusting device of the type mentioned at the outset in order to achieve an extremely thin and thus particularly economical coating application, which in addition to changing swelling allows frequent regrinding of the coating cylinder in the jacket of the coating cylinder.
- the two end bearings of the painting cylinder or the impression cylinder are each arranged in a pivotally mounted on the machine frame side part, for pivoting each side part, a motor spindle articulated with one end to the machine frame and with its other end to the side part , the two end bearing supports of the paint feed roller can be pivoted by means of a motor spindle articulated on the machine frame or lower side part and on the other end on the bearing support, and the axial pressures applied to the four motor spindles can be detected by a pressure sensor and can be set to a preselectable constant value by a pressure regulator connected to the pressure sensor.
- the manual operation on the coating machine for setting the two pressings is therefore reduced to the paired preselection of a setpoint.
- the actual setting is then carried out fully automatically and at a higher speed. Any trend towards a deviating actual value is counteracted immediately during operation.
- the motor spindles of each pair of motor spindles provided on the two machine sides are independent of one another, this ensures that the contact pressure is the same on both sides.
- the motor spindles allow a very sensitive pressure setting and preclude ringing compared to a hydraulic or pneumatic drive. In addition to a gain in quality and safety, there is a reduction in operating effort and a space saving due to the elimination of spindles provided with a handwheel.
- the pivoting position of the coating cylinder or the impression cylinder or the coating feed roller for detecting the stochastic actual diameter of the coating cylinder and thus for adjusting a circumferential speed of the coating cylinder conforming to the impression cylinder can be utilized, whereby the pair of motor spindles in question can have an additional function receives.
- the pair of sub-side parts 10 differ primarily in their shape and in the location of their pivot bearing 12 located on the machine frame 11. Between the motor spindle 13 engaging the sub-side part 10 and the pivot bearing 12, with its end bearing, either the counter-pressure cylinder 14 or the painting cylinder 15 arranged.
- the pivot bearing 16 of each of the two end bearing supports 17 of the paint supply roller 18 is located either on the stationary machine frame 11 or on the lower part part 10 which in turn can be pivoted and the hard counter-pressure cylinder 14 and the two motor spindles 21 are also a special component of the adjusting device 22 for the pressing between the coating cylinder 15 and the coating feed roller 18 of the coating unit 23.
- the entire coating unit 23 is attached to the two pivotable bearing supports 17 of the coating feed roller 18, which, in addition to the coating unit 23, also simplifies the setting device for the pressing pressures exerted on the coating cylinder 15 of the coating machine and simplifies maintenance of the coating machine.
- a Particularly compact and reliable design of the coating unit 23 results from the fact that the coating supply roller 18 and a further coating roller 24 pressed against it are used in the coating unit 23 to limit a coating reservoir 25. They are preferably driven in the opposite direction of rotation and in the region of the reservoir 25 in the downward direction.
- a paint scraper 26 directed with its squeegee blade against the paint supply roller 18 and a paint scraper 27 directed with its squeegee blade against the paint roller 24 are immersed in the horizontal orientation.
- a common holding device is provided in such a way that they can be pivoted away from the lacquer feed roller 18 and the lacquer roller 24 by means of a swivel arm 28 and can be swiveled back and down, and the swivel arms 28 on one to the lacquer supply roller 18 and the further coating roller 24 axially parallel shaft 30 are mounted for longitudinal displacement.
- the two pivotable bearing supports 17 of the paint supply roller 18 and the two motor spindles 21 articulated on the machine frame 11 or side part 10 and on the other side on the bearing support 17 are except for the pressure between the painting cylinder 15 and the paint feed roller 18 are set up to expose the painting cylinder 15.
- the motor spindles 21 have an increased adjustment stroke
- the bearing supports 17 have a more elongated shape
- the pivot bearings 16 have a greater distance from the common contact zone of the coating cylinder 15 and the coating feed roller 18.
- the axial pressures applied to the two motor spindles 13 can be detected by a pressure sensor 31 each and can be adjusted to a preselectable constant value by a pressure regulator 32 connected to the pressure sensor 31.
- a pressure sensor 31 each and can be adjusted to a preselectable constant value by a pressure regulator 32 connected to the pressure sensor 31.
- the actual setting of the pressure between the painting cylinder 15 and the impression cylinder 14 takes place fully automatically and takes into account changing swelling in the jacket 20 of the painting cylinder 15 and regrinding of the painting cylinder 15.
- the same applies to the setting of the pressure between the coating cylinder 15 and the coating feed roller 18, after the axial pressures present on the other two motor spindles 21 can be detected by a pressure sensor 33 and can be adjusted to a preselectable constant value by a pressure regulator 34 connected to the pressure sensor 33 .
- the two motor spindles 13 or the two motor spindles 21 have an additional function. Even with a particularly large diameter range of the coating cylinder 15, which, in addition to changing swelling in the casing 20, permits frequent regrinding, the speed adjustment is thus extremely precise and requires little effort.
- the displacement sensor 35 contains an electrical control resistor of a potentiometer 39 coupled in its rotational movement to the pivoting movement of the side part 10. This results in an additional function for the motor spindle 13 in question and also for the side part 10 it detects and becomes the additional constructional effort for the provision of the speed control was kept extremely small. Characterized in that the pressure sensor 31 assigned to the sub-side part 10 is limited to the central region of the workpieces to the pressure regulator 32, the accuracy of the speed adjustment is further increased.
- the painting machine described With its input-side transport belts 37 and its output-side delivery belts 38, the painting machine described is adapted to the special area of application of one-sided painting of sheet-like sheet metal. However, within the scope of the invention, it can be used quite generally for painting panel-to-sheet workpieces, in particular also those made of cardboard or paper. The improvements in the recess painting are of greater importance, for example, if precise free spaces for adhesive are provided on folding box blanks in the painting.

Abstract
Description
Die Erfindung betrifft eine Einstelleinrichtung für auf den Lackierzylinder einer Lackiermaschine ausgeübte Preßdrücke, bei der die Werkstücke zwischen einem Lackierzylinder mit einem aus Gummi oder einem anderen elastischen Material bestehenden Mantel und einem harten Gegendruckzylinder hindurchbewegt werden, eine erste Anstelleinrichtung für die Pressung zwischen dem Lackierzylinder und dem Gegendruckzylinder vorgesehen ist und eine zweite Anstelleinrichtung für die Pressung zwischen dem Lackierzylinder und einer Lackzuführwalze eines Lackwerkes vorgesehen ist.The invention relates to an adjusting device for pressing pressures exerted on the painting cylinder of a painting machine, in which the workpieces are moved between a painting cylinder with a jacket made of rubber or another elastic material and a hard impression cylinder, a first adjusting device for the pressing between the painting cylinder and the Counter-pressure cylinder is provided and a second adjusting device for pressing between the coating cylinder and a coating feed roller of a coating unit is provided.
Zur Anwendung kommen solche Maschinen beispielsweise in der Fertigung von Getränkedosen, Gläserdeckeln oder Kronenkorken, wo dem Bedrucken ein Innenlackieren und ein Außenlackieren vorausgehen und ein Schutzlackieren nachfolgt. An den Lack werden dort besondere Anforderungen gestellt, damit er beim späteren Stanzen und Tiefziehen nicht platzt. Während frühere Lackiermaschinen die Werkstücke gleichsam mit Lack übergossen, zielen moderne Lackiermaschinen auf einen möglichst sparsamen Lackverbrauch ab. Häufig werden deshalb auf eine Aussparlackierung eingerichtete Lackierzylinder mit exakt positionierten Ausschnitten eingesetzt. Lackierzylinder für eine Vollackierung haben demgegenüber den Vorteil, daß sie viele Male nachgeschliffen und entsprechend länger verwendet werden können. Allerdings muß dann die durch die Durchmesserverminderung bedingte Änderung der Umfangsgeschwindigkeit des Lackierzylinders ausgeglichen werden. Ein Ausgleichsbedarf für die Umfangsgeschwindigkeit des Lackierzylinders besteht in geringerem Ausmaß auch aufgrund einer sich ändernden Quellung im Mantel des Lackierzylinders. Die genaue Einstellung der Pressung zwischen dem Lackierzylinder und dem Gegendruckzylinder sowie der Pressung zwischen dem Lackierzylinder und der Lackzuführwalze ist eine Voraussetzung dafür, daß ein extrem dünner und zugleich äußerst gleichmäßiger Lackauftrag realisiert werden kann.Such machines are used, for example, in the manufacture of beverage cans, glass lids or crown caps, where the printing is preceded by an internal coating and an external coating and a protective coating follows. There are special requirements for the paint provided so that it does not burst during later punching and deep drawing. While previous painting machines poured paint over the workpieces, modern painting machines aim to use paint as economically as possible. For this reason, painting cylinders with precisely positioned cutouts are often used for recess painting. In contrast, painting cylinders for full painting have the advantage that they can be reground many times and used for a correspondingly longer time. However, the change in the peripheral speed of the coating cylinder caused by the reduction in diameter must then be compensated for. There is less need to compensate for the peripheral speed of the painting cylinder due to changing swelling in the jacket of the painting cylinder. The precise setting of the pressure between the coating cylinder and the impression cylinder and the pressure between the coating cylinder and the coating feed roller is a prerequisite for achieving an extremely thin and at the same time extremely uniform coating application.
Eine Einstelleinrichtung der eingangs angeführten Art ist bereits durch ein Eigenfabrikat vom Markt her bekannt. Der Antrieb des Lackierzylinders für eine Vollackierung erfolgt dort über eine druckluftbetätigte Rutschkupplung, die eine feinfühlige Regulierung der Umfangsgeschwindigkeit während des Laufs ermöglicht. Diese Regulierung erfordert jedoch eine Mitwirkung von Bedienungspersonal. Für die Aussparlackierung ist eine elektrische Kontrolleinrichtung eingebaut, welche die starr gekuppelte Zylindereinstellung überwacht. Einschließlich des Entkuppelns zu Einrichtungszwecken sind mit einem Umschalthebel insgesamt drei Betriebszustände einstellbar. Die Einstellung des Lackierzylinders und der Lackzuführwalze, das An- und Abstellen aller Walzen, ihre Parallelstellung und die Dosierung des Lackauftrags sind zentral auf der Bedienungsseite der Maschine zusammengefaßt, wobei mit einem Handrad versehene Spindeln verwendet sind. Nach erfolgter Anstellung zum Betriebszustand können der Lackierzylinder und die Lackzuführwalze spielfrei zum Maschinengestell fixiert werden. Das schließt jedoch über die Mantellinie des Lackierzylinders hinweg örtlich ungleiche Anpreßdrücke einschließlich eventueller Bedienungsfehler nicht mit der inzwischen gewünschten hohen Sicherheit aus.A setting device of the type mentioned is already known from the market through its own manufacture. The painting cylinder for full painting is driven by a compressed air-operated slip clutch, which enables sensitive regulation of the peripheral speed during the run. However, this regulation requires operator participation. An electrical control device is installed for the recess painting, which monitors the rigidly coupled cylinder setting. Including uncoupling for setup purposes, a total of three operating states can be set with a switch lever. The setting of the coating cylinder and the coating feed roller, the switching on and off of all the rollers, their parallel position and the metering of the coating application are summarized centrally on the operating side of the machine, spindles provided with a handwheel being used. After adjustment to the operating state, the coating cylinder and the coating feed roller can be fixed to the machine frame without play. However, this does not preclude locally uneven contact pressures, including possible operating errors, across the surface line of the painting cylinder with the high level of safety that has now been desired.
Der Erfindung liegt die Aufgabe zugrunde, bei einer Einstelleinrichtung der eingangs angeführten Gattung zur Realisierung eines extrem dünnen und damit besonders sparsamen Lackauftrags Ungleichmäßigkeiten in den auf den Lackierzylinder ausgeübten Preßdrücken mit einfachen Mitteln in einem Durchmesserbereich des Lackierzylinders sicher zu vermeiden, der außer einer sich ändernden Quellung im Mantel des Lackierzylinders ein häufiges Nachschleifen des Lackierzylinders zuläßt.The invention is based on the object of reliably avoiding irregularities in the pressing pressures exerted on the coating cylinder by simple means in a diameter range of the coating cylinder in the case of an adjusting device of the type mentioned at the outset in order to achieve an extremely thin and thus particularly economical coating application, which in addition to changing swelling allows frequent regrinding of the coating cylinder in the jacket of the coating cylinder.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die beiden stirnseitigen Lager des Lackierzylinders oder des Gegendruckzylinders in je einem am Maschinengestell schwenkbar gelagerten Subseitenteil angeordnet sind, zum Verschwenken jedes Subseitenteils eine mit ihrem einen Ende am Maschinengestell und mit ihrem anderen Ende am Subseitenteil angelenkte Motorspindel vorgesehen ist, die beiden stirnseitigen Lagerträger der Lackzuführwalze mittels je einer am Maschinengestell oder Subseitenteil und andernends am Lagerträger angelenkten Motorspindel verschwenkbar sind und die an den vier Motorspindeln anstehenden Axialdrücke von je einem Drucksensor erfaßbar und von je einem an den Drucksensor angeschlossenen Druckregler auf einen vorwahlbaren Konstantwert einregelbar eingerichtet sind.This object is achieved in that the two end bearings of the painting cylinder or the impression cylinder are each arranged in a pivotally mounted on the machine frame side part, for pivoting each side part, a motor spindle articulated with one end to the machine frame and with its other end to the side part , the two end bearing supports of the paint feed roller can be pivoted by means of a motor spindle articulated on the machine frame or lower side part and on the other end on the bearing support, and the axial pressures applied to the four motor spindles can be detected by a pressure sensor and can be set to a preselectable constant value by a pressure regulator connected to the pressure sensor.
An der Lackiermaschine reduziert sich demnach die manuelle Bedienung zur Einstellung der beiden Pressungen auf die paarweise Vorwahl je eines Sollwertes. Die eigentliche Einstellung erfolgt dann vollautomatisch und mit einer größeren Geschwindigkeit. Einem etwaigen Trend zu einem abweichenden Istwert wird im Betrieb sofort entgegengesteuert. Obwohl die an den beiden Maschinenseiten vorgesehenen Motorspindeln jedes Motorspindelpaares voneinander unabhängig sind, wird gerade dadurch ein beiderseits gleicher Anpreßdruck garantiert. Die Motorspindeln lassen eine recht feinfühlige Druckeinstellung zu und schließen gegenüber einem hydraulischen oder pneumatischen Antrieb ein Nachschwingen aus. Zusätzlich zu einem Gewinn an Qualität und Sicherheit erreicht man eine Verminderung des Bedienungsaufwandes und eine Platzersparnis aufgrund des Wegfalls mit einem Handrad versehener Spindeln. Mit der Erfindung erzielte Vorteile bestehen aber insbesondere auch darin, daß die Schwenkstellung des Lackierzylinders oder des Gegendruckzylinders oder der Lackzuführwalze zum Erfassen des stochastischen Istdurchmessers des Lackierzylinders und damit zum Einregeln einer dem Gegendruckzylinder konformen Umfangsgeschwindigkeit des Lackierzylinders verwertet werden kann, wodurch das betreffende Motorspindelpaar eine Zusatzfunktion erhält.The manual operation on the coating machine for setting the two pressings is therefore reduced to the paired preselection of a setpoint. The actual setting is then carried out fully automatically and at a higher speed. Any trend towards a deviating actual value is counteracted immediately during operation. Although the motor spindles of each pair of motor spindles provided on the two machine sides are independent of one another, this ensures that the contact pressure is the same on both sides. The motor spindles allow a very sensitive pressure setting and preclude ringing compared to a hydraulic or pneumatic drive. In addition to a gain in quality and safety, there is a reduction in operating effort and a space saving due to the elimination of spindles provided with a handwheel. Advantages achieved with the invention are, in particular, that the pivoting position of the coating cylinder or the impression cylinder or the coating feed roller for detecting the stochastic actual diameter of the coating cylinder and thus for adjusting a circumferential speed of the coating cylinder conforming to the impression cylinder can be utilized, whereby the pair of motor spindles in question can have an additional function receives.

In den beiden Alternativen unterscheiden sich die paarweise vorhandenen Subseitenteile 10 vorrangig in ihrer Form und im Ort ihres am Maschinengestell 11 befindlichen Schwenklagers 12. Zwischen der am Subseitenteil 10 angreifenden Motorspindel 13 und dem Schwenklager 12 ist mit seinem stirnseitigen Lager entweder der Gegendruckzylinder 14 oder der Lackierzylinder 15 angeordnet. Das Schwenklager 16 jedes der beiden stirnseitigen Lagerträger 17 der Lackzuführwalze 18 befindet sich entweder am ortsfesten Maschinengestell 11 oder am seinerseits verschwenkbaren Subseitenteil 10. Die beiden Motorspindeln 13 sind ein besonderer Bestandteil der Anstelleinrichtung 19 für die Pressung zwischen dem einen Mantel 20 aus Gummi aufweisenden Lackierzylinder 15 und dem harten Gegendruckzylinder 14 und die beiden Motorspindeln 21 ebenso ein besonderer Bestandteil der Anstelleinrichtung 22 für die Pressung zwischen dem Lackierzylinder 15 und der Lackzuführwalze 18 des Lackwerkes 23.In the two alternatives, the pair of
Vorteilhafterweise ist an den beiden verschwenkbaren Lagerträgern 17 der Lackzuführwalze 18 das gesamte Lackwerk 23 angebracht, was außer dem Lackwerk 23 auch die Einstelleinrichtung für die auf den Lackierzylinder 15 der Lackiermaschine ausgeübten Preßdrücke vereinfacht und die Wartung der Lackiermaschine erleichtert. Eine besonders kompakte und funktionssichere Bauform des Lackwerks 23 ergibt sich dadurch, daß im Lackwerk 23 die Lackzuführwalze 18 und eine gegen diese gedrückte weitere Lackwalze 24 zur Begrenzung eines Lackvorratssees 25 verwendet sind. Sie werden vorzugsweise mit gegenläufigem Drehsinn und im Bereich des Lackvorratssees 25 in Abwärtsrichtung drehend angetrieben. Im Lackvorratssee 25 sind in horizontaler Ausrichtung untergetaucht ein mit seiner Rakelschneide gegen die Lackzuführwalze 18 gerichteter Lackabstreicher 26 und ein mit seiner Rakelschneide gegen die Lackwalze 24 gerichteter Lackabstreicher 27 angeordnet. Für die beiden Lackabstreicher 26 und 27 ist eine gemeinsame Halteeinrichtung dergestalt vorgesehen, daß sie mittels eines Schwenkarme 28 aufweisenden Tragbalkens 29 von der Lackzuführwalze 18 und der Lackwalze 24 nach oben wegschwenkbar und nach unten zurückschwenkbar sind und die Schwenkarme 28 an einer zu der Lackzuführwalze 18 und der weiteren Lackwalze 24 achsparallelen Welle 30 längsverschiebbar gelagert sind.Advantageously, the
Zur bequemeren Reinigung der Lackiermaschine in Bezug auf einen schnellen Lackwechsel und zur Erleichterung anderer Wartungsarbeiten sind die beiden verschwenkbaren Lagerträger 17 der Lackzuführwalze 18 und die beiden am Maschinengestell 11 oder Subseitenteil 10 und andernends am Lagerträger 17 angelenkten Motorspindeln 21 außer für die Pressung zwischen dem Lackierzylinder 15 und der Lackzuführwalze 18 für die Freilegung des Lackierzylinders 15 eingerichtet. Aus diesem Grunde erhalten die Motorspindeln 21 einen vergrößerten Verstellhub, die Lagerträger 17 eine gestrecktere Form und die Schwenklager 16 einen größeren Abstand von der gemeinsamen Berührungszone des Lackierzylinders 15 und der Lackzuführwalze 18.For more convenient cleaning of the painting machine in relation to a quick paint change and to facilitate other maintenance work, the two pivotable bearing supports 17 of the
Die an den beiden Motorspindein 13 anstehenden Axialdrücke sind von je einem Drucksensor 31 erfaßbar und von je einem an den Drucksensor 31 angeschlossenen Druckregler 32 auf einen vorwählbaren Konstantwert einregelbar eingerichtet. Damit erfolgt die eigentliche Einstellung der Pressung zwischen dem Lackierzylinder 15 und dem Gegendruckzylinder 14 vollautomatisch und wird einer sich ändernden Quellung im Mantel 20 des Lackierzylinders 15 und einem Nachschliff des Lackierzylinders 15 Rechnung getragen. Entsprechendes gilt für die Einstellung der Pressung zwischen dem Lackierzylinder 15 und der Lackzuführwalze 18, nachdem die an den anderen beiden Motorspindeln 21 anstehenden Axialdrücke von je einem Drucksensor 33 erfaßbar und von je einem an den Drucksensor 33 angeschlossenen Druckregler 34 auf einen vorwählbaren Konstantwert einregelbar eingerichtet sind.The axial pressures applied to the two
Indem die Schwenkstellung des Lackierzylinders 15 oder des Gegendruckzylinders 14 oder der Lackzuführwalze 18 von einem Wegsensor 35 erfaßbar gemacht ist und das Lagesignal des Wegsensors 35 bei eingeregelter Pressung in einem Drehzahlregler 36 für eine zum Gegendruckzylinder 14 konforme Umfangsgeschwindigkeit des Lackierzylinders 15 als Regelgröße verwendet ist, erhalten die beiden Motorspindeln 13 oder die beiden Motorspindeln 21 eine Zusatzfunktion. Selbst bei einem besonders großen Durchmesserbereich des Lackierzylinders 15, der außer einer sich ändernden Quellung im Mantel 20 ein häufiges Nachschleifen zuläßt, gestaltet sich die Drehzahlanpassung damit äußerst präzise und aufwandsarm. Durch die Drehzahlanpassung werden unbenutzte Lackfelder des Lackierzylinders 15 zur Sauberhaltung der Unterseite der mit Abstand aufeinanderfolgenden Werkstücke auf dem Mantel 20 des Lackierzylinders 15 ortsfest gehalten. Dazu gehört, daß die in Ergänzung eingangsseitiger Transportriemen 37 zum Abtransport der Werkstücke vorgesehenen Auslageriemen 38 in ihrem Umlauf taktgleich mit einer Umdrehung des Gegendruckzylinders 14 angetrieben sind.By making the swivel position of the
In der bevorzugten Ausführungsform enthält der Wegsensor 35 einen elektrischen Regelwiderstand eines in seiner Drehbewegung an die Schwenkbewegung des Subseitenteils 10 gekoppelten Potentiometers 39. Damit ergibt sich außer für die betreffende Motorspindel 13 auch für das von ihr erfaßte Subseitenteil 10 eine Zusatzfunktion und wird der bauliche Mehraufwand für das Vorsehen der Drehzahlregelung extrem klein gehalten. Dadurch, daß der dem Subseitenteil 10 zugeordnete Drucksensor 31 auf den Mittelbereich der Werkstücke begrenzt zum Druckregler 32 durchgeschaltet ist, wird die Genauigkeit der Drehzahlanpassung weiter gesteigert.In the preferred embodiment, the
Mit ihren eingangsseitigen Transportriemen 37 und ihren ausgangsseitigen Auslageriemen 38 ist die beschriebene Lackiermaschine dem speziellen Einsatzbereich des einseitigen Lackierens tafelförmiger Feinbleche angepaßt. Sie läßt sich aber im Rahmen der Erfindung ganz generell zum Lackieren tafel- bis blattförmiger Werkstücke verwenden, also insbesondere auch solcher aus Karton oder Papier. Die Verbesserungen in der Aussparlackierung sind beispielsweise dann von größerer Bedeutung, wenn an Faltschachtelzuschnitten in der Lackierung präzise Freiplätze für Klebstoff vorgesehen werden.With its input-
