Description

Die vorliegende Erfindung betrifft eine Maschine zur Beschriftung von Stückgütern mit unregelmässiger Beschriftungsoberflächenhöhe, nämlich von unsortierten Eiern unterschiedlicher Grösse, die auf einem Eierkarton angeordnet sind, mit den Merkmalen des Oberbegriffes des Patentanspruches 1.The present invention relates to a machine for labeling of piece goods with irregular labeling surface height, namely unsorted eggs of different Size arranged on an egg carton are, with the features of the preamble of the claim 1.

Immer häufiger werden Eier mit unterschiedlichen Informationen beschriftet. Neben dem Legedatum werden beispielsweise der Name des Lieferanten, eine Kontrollnummer sowie die Haltungsart der Hühner auf die Eier aufgedruckt. Damit trotz allen Informationen nicht das gesamte Ei vollständig bedruckt sein muss, wird mit immer kleinerer Schrift gearbeitet. Dies verlangt eine optimal arbeitende Maschine zur Beschriftung von Eiern. Dabei ist zu beachten, dass bei steigendem Qualitätsbedarf gleichzeitig eine quantitative Steigerung erwünscht wird. Diese beiden Ziele widersprechen sich normalerweise. Eggs with different information are becoming increasingly common labeled. In addition to the laying date, for example the name of the supplier, a control number and the type of keeping the chickens are printed on the eggs. So despite all information, the entire egg is not completely printed must be, is working with ever smaller font. This requires an optimally working machine for labeling of eggs. It should be noted that with increasing quality requirements at the same time a quantitative increase is desired becomes. These two goals are usually contradictory.

Maschinen zur Beschriftung von Eiern sind entsprechend bekannt. Während ältere Systeme wie beispielsweise aus den US-3 094 920 und US-1 906 094 noch mit Kontaktdruck arbeiteten, beispielsweise mittels Stempel- oder Tampondruckvorrichtungen, arbeiten moderne Eierbeschriftungsmaschinen mit Tintenstrahldrucker, wie sie aus der Computertechnik bekannt und in der DE-4 414 477 A sowie der US-4 843 958 A offenbart sind. Dies hat den Vorteil, dass man auch eine graphische Gestaltung ohne grossen Aufwand über einen PC erreichen kann.Machines for labeling eggs are known accordingly. While older systems such as those from US-3 094 920 and US-1 906 094 still worked with contact pressure, for example by means of stamp or pad printing devices, modern egg labeling machines work with inkjet printers, as they are known from computer technology and in DE-4 414 477 A and US-4 843 958 A are disclosed. This has the advantage that you can also get a graphic design can be reached easily using a PC.

Während in grossen Hühnerfarmen die Eier gereinigt und sortiert zur Beschriftungsmaschine gelangen und diese entsprechend unter annähernd identischen Verhältnissen sehr schnell arbeiten können, ist dies bei landwirtschaftlichen Betrieben, die Hühnerhaltung als Nebenverdienst haben, nicht der Fall. Hier gelangen die Eier meist unsortiert auf sogenannte Eierhöckerkartons, und diese Kartons mit den Eiern werden in entsprechende Beschriftungsmaschinen eingelegt, worauf ein fahrbarer Druckkopf entsprechend der Rasterung der Eierkartons über die Eier, die sich darauf befinden, kontaktlos hinweg bewegt wird, wobei der Druckkopf vertikal über jedem Ei mit gleichbleibender Distanz in bezug auf die Höhe des Eierkartons jeweils anhält und jedes Ei mit einem Tintenstrahldrukker beschriftet.While in large chicken farms the eggs are cleaned and sorted get to the labeling machine and this accordingly very quickly under almost identical conditions can work, this is on farms, who keep chicken as a secondary income, not the case. Here the eggs are usually unsorted on so-called egg hump boxes, and these boxes with the eggs are in appropriate Inscription machines inserted, on which a mobile Printhead according to the grid of the egg cartons contactless over the eggs that are on it with the printhead vertically above each egg constant distance in relation to the height of the egg carton each stops and each egg with an inkjet printer labeled.

Der Grössenunterschied der nicht sortierten Eier ist erheblich. Entsprechend wird der Druckkopf mit einem Sicherheitsabstand über die Eier hinweg bewegt. Die Kleinheit jedoch der gewünschten Schrift führt nun dazu, dass diese bei grossen Eiern, bei denen somit der Abstand zum Tintenstrahldruckkopf relativ klein ist, exakt und kräftig erkennbar ausfällt, während bei kleinen Eiern, der Tintenstrahl bis zum Auftreffen auf das Ei zu weit von der Düse des Tintenstrahldruckers entfernt ist und somit die Schrift verschwommen wird. Ein weiteres Problem besteht darin, dass die Eier nicht besonders genau vertikal ausgerichtet in den Eierkartons liegen. Dies führt zusätzlich dazu, dass der Druckstrahl mit einem relativ grossen Abweichungswinkel von der Vertikalen auf die Eioberfläche auftritt, wodurch die gesamte Beschriftung erheblich verzerrt wird.The size difference of the unsorted eggs is considerable. Accordingly, the print head is kept at a safety distance moved over the eggs. The smallness however desired font now leads to this in large Eggs, which are the distance to the inkjet printhead is relatively small, precise and clearly recognizable, while for small eggs, the ink jet until it hits too far from the nozzle of the inkjet printer for the egg and so the writing becomes blurred. Another one Problem is that the eggs are not particularly accurate lie vertically aligned in the egg cartons. This additionally leads to the pressure jet having a relative large angle of deviation from the vertical to the egg surface occurs, which makes the entire label considerably is distorted.

Meist werden die gleichen oder ähnlichen Informationen auch auf den Eierschachteln angebracht. Die Schachteln, die auch nebeneinander gestellt werden und dann vom Druckkopf überfahren werden, haben recht unterschiedliche Deckelhöhen, einerseits durch qualitative Unterschiede andererseits weil oft die Schachteln nicht vollständig korrekt verschlossen sind.Mostly the same or similar information too attached to the egg boxes. The boxes, too placed side by side and then run over by the printhead have quite different lid heights, on the one hand due to qualitative differences on the other hand because often the boxes are not completely closed properly.

Stempel- oder Tampondruckvorrichtungen erfordern einen direkten Kontakt. Dies wird gemäss der US-3'094'920-A und der US-1'906'094-A durch gefederte Stempel erreicht. Eierbeschriftungsmaschinen mit Tintenstrahldrucker gemäss DE-44'14'477-A und US-4'843'958-A ordnen den Tintenstrahldrucker fest an. Stamp or pad printing devices require a direct one Contact. This is according to US-3'094'920-A and US-1'906'094-A achieved by spring-loaded stamp. Egg marking machines with inkjet printer according to DE-44'14'477-A and US-4'843'958-A fix the ink jet printer.

Es ist daher die Aufgabe der vorliegenden Erfindung eine Maschine zur Beschriftung von Stückgütern mit unterschiedlicher Beschriftungsoberflächenhöhe, nämlich unsortierten Eiern unterschiedlicher Grösse, die auf einem Eierkarton angeordnet sind, bereitzustellen, ohne dass dabei eine merkbare Qualitätseinbusse stattfindet. It is therefore the object of the present invention a machine for labeling piece goods with different Labeling surface height, namely unsorted eggs of different Size arranged on an egg carton, to provide without a noticeable loss of quality takes place.

Diese Aufgabe löst eine Maschine mit den Merkmalen des Patentanspruches 1. Dank des Vorhandenseins eines Tastfusses an einem vertikal beweglichen Arm, kann nun der Tintenstrahldrucker mit der Tintenpatrone unter gleichbleibender Distanz zur Eioberschale über dieselbe hinweg bewegt werden.This object is achieved by a machine with the features of the patent claim 1. Thanks to the presence of a tactile foot a vertically movable arm, the inkjet printer can now with the ink cartridge under constant Distance to the egg shell can be moved over it.

Die Länge des Tastfusses in bezug auf die Bewegungsrichtung beeinflusst im wesentlichen die mögliche maximale Anpassung der Bewegung an die Eioberfläche. Ist der Tastfuss sehr kurz, so treten äusserst starke Auf- und Abbewegungen auf, die bei den erforderlichen Druckgeschwindigkeiten zu einem Tanzen des Tastfusses auf den Eiern führen können. Es hat sich daher als besonders vorteilhaft erwiesen, wenn die Länge des Tastfusses in bezug auf die Bewegungsrichtung mindestens die Länge von zwei einander in einem Eierhöckerkarton benachbarten Eiern aufweist. Eine verbesserte Anpassung des Tastfusses an die zu bedruckende Oberfläche kann zudem erreicht werden, indem der Tastfuss am vertikal beweglichen Arm um eine parallel zur Längserstreckung des Tastfusses verlaufenden Achse schwenkbeweglich ist. Damit ist auch sichergestellt, dass Eier, die nicht exakt vertikal in den Eierkarton gestellt worden sind, korrekt beschriftbar sind.The length of the stylus in relation to the direction of movement essentially affects the possible maximum adjustment the movement to the egg surface. If the tactile foot is very short, so extremely strong up and down movements occur, which at the required print speeds to dance the Feet can lead on the eggs. It has therefore proven to be proven particularly advantageous when the length of the feeler with respect to the direction of movement at least the length of two eggs next to each other in an egg carton having. An improved adaptation of the tactile foot to the printing surface can also be achieved by the Feet on the vertically movable arm parallel to the Axis extending longitudinally of the sensing foot pivotable is. This also ensures that eggs that have not been placed exactly vertically in the egg carton, can be labeled correctly.

Ist an einem der beiden parallelen Schwenkarme der Parallelogrammlenkung eine mit dem Gehäuse verbundene, einstellbare Zugfeder angeordnet, so kann damit das am Vertikal-Arm anliegende Gewicht kompensiert werden. Dies ist vor allem deshalb von Vorteil, weil die mit dem Druckkopf kombinierte Tintenpatrone sich während des Druckens langsam entleert. Somit muss die Einstellung der Gewichtskompensation während der Benutzung nachgeregelt werden können. Andernfalls wäre der Tastfuss bei voller Tintenpatrone zu träge, und bei den hier auftretenden Arbeitsgeschwindigkeiten könnten Eier zerstört werden und somit der Druckkopf verkleben. Würde man jedoch die Gewichtskompensation nur auf den Drucker mit voller Patrone einstellen, so würde der Tastkopf zu tanzen beginnen, so bald sich die Patrone weitgehend entleert hat. Prinzipiell kann man hierzu auch schwingungsdämmende Mittel vorsehen. Eine Möglichkeit, die ohne zusätzlichen Kostenaufwand realisierbar ist, besteht darin, die Steuerleitungen zwischen Druckkopf und dem fahrbaren Gehäusekopf als gewölbt verlaufendes Flachkabel zu gestalten, welches dann eine schwingungsdämmende Wirkung ausüben wird.Is on one of the two parallel swivel arms of the parallelogram steering an adjustable one connected to the housing Tension spring arranged so that it can be applied to the vertical arm Weight to be compensated. This is mainly because of that advantageous because the ink cartridge combined with the printhead empties slowly while printing. So must the setting of the weight compensation during use can be adjusted. Otherwise it would be Feet too sluggish when the ink cartridge is full, and here occurring working speeds could destroy eggs and thus stick the printhead. Would you however the weight compensation only on the printer with a full cartridge the probe would start to dance, as soon as the cartridge has largely emptied. in principle one can also provide anti-vibration means. A possibility that can be realized without additional costs is, the control lines between Printhead and the mobile housing head as a curved To design flat cable, which is then a vibration-damping Will have an effect.

Weitere vorteilhafte Ausgestaltungsformen des Erfindungsgegenstandes gehen aus den abhängigen Ansprüchen hervor, und deren Bedeutung, sofern nicht bereits beschrieben, geht aus der nachfolgenden Beschreibung hervor.Further advantageous embodiments of the subject matter of the invention emerge from the dependent claims, and their meaning, unless already described, goes out the following description.

In der Zeichnung ist ein bevorzugtes Ausführungsbeispiel des Erfindungsgegenstandes vereinfacht dargestellt. Hierbei wurden lediglich die für die Erfindung wesentlichen Elemente dargestellt, während der gesamte Gehäuseanteil, der Steuer- und Antriebsteil des fahrbaren Kopfes sowie der Aufnahmebereich für die Stückgüter beziehungsweise der Eierkartons allesamt weggelassen wurden. Nur der für die Erfindung wichtige fahrbare Kopf, an dem der hin und her bewegbare Tintenstrahldrucker mechanisch befestigt ist, wurde dargestellt. Es zeigt:

Sämtliche erfindungswesentlichen Teile sind allein schon aus der Figur 1 ersichtlich. Die gesamte Maschine, die insbesondere die Schienen zur Bewegung des fahrbaren Wagens 1 umfasst, sowie die entsprechenden Antriebs- und Steuerungsmittel sind hier weggelassen worden, da sie in ihrer Gestaltung ohne Änderung beibelassen werden können, so dass lediglich, die für die Erfindung hier wesentlichen Elemente dargestellt sind. Dies betrifft insbesondere den fahrbaren Wagen 1. Dieser ist entsprechend des Doppelpfeiles B hin und her bewegbar. Die Bewegung vertikal zur Zeichnungsebene erfolgt bei gewissen Eierbeschriftungsmaschinen ebenfalls durch Verschiebung des Wagens 1, bei einfacheren Anlagen wird jedoch bevorzugterweise der Eierhöckerkarton K um eine Reihe weiter verschoben. Damit beschränkt sich die Bewegung des fahrbaren Wagens 1 auf eine reine Hin- und Herbewegung.All parts essential to the invention are already out of Figure 1 can be seen. The whole machine, in particular comprises the rails for moving the mobile carriage 1, as well as the corresponding drive and control means have been omitted here because of their design can be left unchanged so that only the elements essential to the invention shown here are. This applies in particular to the mobile wagon 1. This can be moved back and forth according to the double arrow B. The movement vertical to the drawing plane takes place at certain egg labeling machines also by shifting of the car 1, however, with simpler systems preferably the egg hump carton K one row further postponed. This limits the movement of the mobile Wagens 1 on a pure back and forth movement.

Der Wagen 1, der auch als fahrbarer Kopf bezeichnet wird, umfasst eine Tragplatte 10, an der ein Gehäuse 11 anschliesst. Innerhalb des Gehäuses 11 ist eine Parallelogrammlenkung 5 schwenkbeweglich angeordnet. Die Parallelogrammlenkung besteht aus den beiden schwenkbaren, parallelen Führungsarmen 12, die einseitig über Achsen 13, 13' mit festen Teilen des fahrbaren Wagens 1, beispielsweise mit dem Gehäuse 11, schwenkbar verbunden sind. Die beiden gegenüberliegenden Enden der schwenkbaren Führungsarme 12 sind gelenkig mit einem vertikal beweglichen Arm 4 verbunden. Um eine möglichst leicht gängige Bewegung zu erreichen, sind sämtliche Lager 13 als Kugellager ausgestaltet. Dies ist beispielsweise aus der Figur 2 ersichtlich. Im dargestellten Beispiel ist lediglich die Achse 13' mit dem Gehäuse 11 verbunden. Die Parallelogrammlenkung 5 erlaubt somit eine exakt vertikale Auf- und Abbewegung des beweglichen Armes 4. Am Ende dieses beweglichen Armes 4 ist der Tintenstrahldrucker 2 mit seiner Tintenpatrone auswechselbar befestigt. Er ist dabei im wesentlichen form- und kraftschlüssig im Tastfuss 3 gehalten. Der Tintenstrahldrukker 2, der ein handelsübliches Element ist, wird über eine Steuerleitung 6 gesteuert und gespeist. Die Steuerleitung 6 wird bevorzugterweise als Flachkabel gestaltet. Dieses Flachkabel stellt die Verbindung zwischen dem Tintenstrahldrucker 2 und einer Steuereinheit, die hier nicht dargestellt ist, dar. Das Kabel verläuft im hier sichtbaren Bereich lediglich zwischen dem Tintenstrahldrucker 2 und dem Wagen 1. Da sich der Tintenstrahldrucker 2 in Relation zum Wagen 1 auf und ab bewegen sowie eine beschränkte Schwenkbewegung durchführen kann, muss die Steuerleitung, die als Flachkabel gestaltet ist, genügend lang gestaltet sein, um diesen Bewegungen folgen zu können.The carriage 1, which is also referred to as a mobile head, comprises a support plate 10 to which a housing 11 connects. There is a parallelogram steering 5 within the housing 11 arranged pivotably. The parallelogram steering exists from the two swiveling, parallel guide arms 12, one-sided via axles 13, 13 'with fixed parts of the mobile Wagens 1, for example with the housing 11, pivotable are connected. The two opposite ends of the pivotable guide arms 12 are articulated with a vertical movable arm 4 connected. To make it as easy as possible To achieve movement, all bearings 13 are ball bearings designed. This can be seen, for example, from FIG. 2. In the example shown, only the axis is 13 'connected to the housing 11. The parallelogram steering 5 thus allows an exact vertical up and down movement of the movable arm 4. At the end of this movable arm 4 is the inkjet printer 2 with its ink cartridge replaceable attached. He is essentially form and held frictionally in the foot 3. The inkjet printer 2, which is a commercially available item, is about a Control line 6 controlled and fed. The control line 6 is preferably designed as a flat cable. This flat cable establishes the connection between the inkjet printer 2 and a control unit, which is not shown here, The cable only runs in the area visible here between the inkjet printer 2 and the carriage 1. Because the inkjet printer 2 in relation to the carriage 1 up and down move and perform a limited swivel movement can, the control line, which is designed as a flat cable is designed to be long enough to follow these movements to be able to.

Am vertikalen, beweglichen Arm 4 ist eine Aufnahme 7 schwenkbeweglich angeordnet. Die Schwenkbewegung erfolgt um eine Anpassachse 8, die parallel zur Längsverlaufsrichtung des Tastfusses 3 angeordnet ist und den vertikalen, beweglichen Arm 4 durchsetzt. Damit kann der Tastfuss 3 sowohl eine Auf- und Abbewegung als auch eine seitliche Schwenkbewegung durchführen. Der eigentliche Tastfuss 3 ist mit der Aufnahme 7 verbunden. Der Tastfuss 3 ist in den Figuren 4a und 4b detailliert dargestellt. Er besteht im wesentlichen aus einer gewölbten Kufe 30, die einen in Längsrichtung verlaufenden Schlitz 31 aufweist. An der Kufe 30 ist seitlich ein stufenförmig gestaltetes Befestigungsblech 32 vorgesehen. Der Tintenstrahldrucker 2 ist auf der Aufnahme 7 so gehalten, dass er genau über den Schlitz 31 in der Kufe 30 angeordnet ist, wobei sichergestellt ist, dass das abgetastete Ei mit dem Tintenstrahldrucker selber nicht in Berührung kommen kann. Ein Problem bei diesen schnell arbeitenden Eierbeschriftungsmaschinen besteht darin, dass bei der Abtastung entlang den Eiern erhebliche Auf- und Abbewegungen stattfinden, so dass die Bewegung äusserst leichtgängig erfolgen muss, ohne dass dabei der Tastfuss 3 über die Eier hinweg zu tanzen beginnt. Hierzu sind verschiedene Vorkehrungen vorgesehen. Einerseits erfolgt über eine Zugfeder 14 ein Gewichtsausgleich, um das Gewicht des Tastfusses 3, des Tintenstrahldruckers 2, der Aufnahme 7 und des beweglichen Armes 4 weitgehend zu kompensieren. Trotz dieser Kompensation wurden während des Bedruckens immer noch Eier zerschlagen, was längere Zeit unerklärlich schien. Nach längeren Versuchen stellte man jedoch fest, dass Eier nur dann zerschlagen worden sind, wenn die Tintenpatrone 2' des Druckers 2 annähernd leer war. In diesem Falle begann der Tastfuss zu schwingen. Entsprechend wurde eine Regulierschraube 15 vorgesehen, mittels derer die Kompensation des Gewichtes entsprechend dem Gewicht der Tintenpatrone angepasst werden konnte. Ein weiterer Vorteil wurde erreicht, indem eine verstellbare Anschlagschraube 16 angebracht wurde, mittels derer die freie Beweglichkeit des vertikal beweglichen Armes 4 begrenzt werden kann. Ist beispielsweise auf dem Eierkarton K eine Lücke vorhanden, so wird hiermit sichergestellt, dass der Drucker nicht in diesen Bereich hinuntersinken kann. Andernfalls würde der Gleitbügel 30 des Tastfusses 3 am nachfolgenden Ei unter Umständen seitlich anschlagen und dieses zerstören.On the vertical, movable arm 4, a receptacle 7 is pivotable arranged. The swiveling movement takes place around an adjustment axis 8, which is parallel to the longitudinal direction of the Feet 3 is arranged and the vertical, movable Arm 4 penetrates. The touch foot 3 can thus both and downward movement as well as a lateral pivoting movement. The actual touch foot 3 is with the receptacle 7 connected. The feeler foot 3 is detailed in FIGS. 4a and 4b shown. It essentially consists of one arched runner 30, which has a longitudinal direction Has slot 31. On the runner 30 is a step-shaped side designed mounting plate 32 provided. The inkjet printer 2 is held on the receptacle 7 so that it is arranged exactly over the slot 31 in the runner 30, ensuring that the scanned egg matches the Inkjet printer itself cannot come into contact. A problem with these fast-working egg labeling machines is that when scanning along the Eggs significant up and down movements take place so that the movement must be extremely smooth, without the tactile foot 3 begins to dance across the eggs. Various precautions are provided for this. On the one hand weight compensation takes place via a tension spring 14 in order to Weight of the foot 3, the inkjet printer 2, the Recording 7 and the movable arm 4 largely to compensate. Despite this compensation, during the Printing still smashed eggs, which is inexplicable for a long time appeared. After long attempts, however, they asked found that eggs were only broken when the Ink cartridge 2 'of printer 2 was almost empty. In this Trap the stylus started to swing. Correspondingly a regulating screw 15 is provided, by means of which the compensation the weight corresponding to the weight of the ink cartridge could be adjusted. Another advantage was achieved by an adjustable stop screw 16 attached by means of which the free mobility of the vertical movable arm 4 can be limited. For example there is a gap on the egg carton K, see above This ensures that the printer is not in this Area can sink. Otherwise, the slide bracket 30 of the tactile foot 3 on the following egg under certain circumstances strike and destroy it.

Prinzipiell kann die Parallelogrammlenkung 5 nicht nur in bezug auf das anhängende Gewicht kompensiert werden, sondern es kann auch in seiner Bewegung gedämpft werden. Die einfachste Form besteht darin, die Steuerleitung 6 als ein relativ steifes Flachkabel zu gestalten. Damit sind zusätzliche Mittel nicht mehr erforderlich. Es ist jedoch auch durchaus denkbar, eines der Gelenke der Parallelogrammlenkung als Kunststoffgelenk zu gestalten, das eine etwas erhöhte Reibung aufweist und somit eine dämpfende Funktion ausübt.In principle, the parallelogram steering 5 can not only in relation be compensated for the attached weight, but it can also be dampened in its movement. The easiest Form is the control line 6 as a relatively rigid To design flat cables. That means additional funds not necessary anymore. However, it is also conceivable one of the joints of the parallelogram steering as a plastic joint to design that has a slightly increased friction and thus has a dampening function.

An sich wird die Parallelogramm-Anordnung gewählt, um eine leicht bewegliche Führung des Druckers zu erzielen, der eine Dämpfung ermöglicht, ohne dass zu starke vertikale Beschleunigungskräfte auf die Eier wirken. Dasselbe kann auch erreicht werden, wenn man den Drucker an einem genügend langen Schwenkarm anordnet. Dann führt der Druckkopf eine quasi-vertikale Bewegung aus, die aber auch gedämpft werden kann, ohne dass die gesamte Massenträgheit bei der Vertikalbewegung auftritt. Insofern sind also auch Lösungen mit einem Schwenkarm als gleichwirkende Variante zum Parallelogramm anzusehen.As such, the parallelogram arrangement is chosen to be one to achieve easy moving guidance of the printer, the one Damping allows for vertical without being too strong Accelerating forces act on the eggs. The same can also can be achieved if you have the printer at a sufficient arranges long swivel arm. Then the printhead guides one quasi-vertical movement, but which are also dampened can without the entire inertia at Vertical movement occurs. In this respect, there are also solutions with a swivel arm as a variant with the same effect Watch the parallelogram.
