Definitions
- the invention relates to a screen preparation system, in particular for a printing device, in particular a 3D screen printing device, which has a screen holder for a printing screen and a doctor device assigned to the printing screen.
- Printing devices which use a doctor blade device and a printing screen, also referred to as a printing mask, to apply a material layer with a structure determined by the printing screen to a substrate are known from the prior art.
- a doctor blade device and a printing screen also referred to as a printing mask
- the use of the printing screen has the advantage that the structures can be applied multiple times to multiple substrates or to one substrate multiple times in a simple manner.
- the focus is on time and cost advantages.
- An alternative to this is to apply conductor track structures in a targeted manner by means of a spray nozzle, this being disadvantageous in terms of time and cost in comparison with the previously mentioned printing device.
- a disadvantage of screen printing devices is that different printing screens have to be used to produce different structures. This means an increased effort for the user because he has to replace the pressure screen, clean it and replace it with a new pressure screen that has to be refilled.
- document DE-A-26 43 226 discloses a screen delivery system according to the preamble of claim 1.
- the invention has for its object to provide a screen preparation system that reduces processing time, improves material utilization and ensures a safe printing process.
- the object on which the invention is based is achieved by the provision device having the features of claim 1.
- This has the advantage that a printing screen for a printing process, in particular for printing three-dimensionally shaped structures, is made available automatically, and furthermore preparatory and postprocessing steps are facilitated and in some cases completely avoided. This allows the throughput of the Printing device is increased and the load on the user is reduced, the printing result or the printing quality not being adversely affected thereby.
- the screen preparation system is characterized in that it has a transport device for transporting a pressure screen in each case, as well as at least one screen magazine which has a multiplicity of screen bearings for receiving a pressure screen in each case, and in particular at least one treatment station for treating the pressure screens, the transport device for this purpose is designed to operate the at least one sieve magazine and in particular the at least one treatment station with pressure sieves.
- the screen preparation system thus has a screen magazine for holding a large number of printing screens. This makes it possible to store a large number of identical and / or different printing screens in the screen magazine when they are not required for a printing process. This centralized storage ensures easy handling of a large number of printing screens.
- the printing screens preferably have markers, and the screen magazine has a detection device in order to detect the presence and position of printing screens in the screen magazine, so that the desired printing screen can be removed from the screen magazine in a simple manner if necessary.
- existing printing screens can in particular be pretreated or post-treated in order to make the printing process of a printing device efficient.
- the treatment station is designed to take over tasks that are otherwise incumbent on the user and thereby to simplify a printing process. Because the transport device reaches and operates both the treatment station and the screen magazine, the printing screens can be moved automatically from the screen magazine to the treatment station and vice versa by means of the transport device, so that the pre-treatment or post-treatment of a print screen takes place automatically.
- storage in the screen magazine has the advantage that it is not absolutely necessary to clean a printing screen after a printing process has been carried out. Instead, the printing screen is stored in the screen magazine with remnants of printing mass remaining on it until it is required again for a printing process with the same printing mass. This means that a cleaning step can also be dispensed with entirely.
- the screen preparation system has a screen use station that can be operated by the transport device with the printing screens.
- a screen usage station understood a station in which the sieve is used for its actual purpose. This means that the user does not have to remove a screen from the screen magazine himself and feed it to a printing device, for example. Rather, a printing screen is automatically made available to the user and / or a printing device.
- the sieve magazine is designed so that the user himself can remove a desired pressure sieve there.
- the screen magazine can be open on two sides, for example, the transport device having access to the printing screens on one side and the user on the other side.
- the screen use station is a screen removal station for the user.
- the user selected printing screen is thus made available to the user at the removal station, so that the user does not have to search for the suitable printing screen in the magazine himself.
- the removal station has a screen storage in which the transport device can place the selected printing screen for removal.
- the screen use station is a printing device.
- the transport device is thus designed to feed a selected printing screen directly to a printing device for carrying out a printing process.
- the transport device is designed to insert the selected printing screen into the screen holder of the printing device or to arrange it there, so that a printing process can subsequently be carried out automatically.
- the printing device is designed for printing three-dimensionally shaped structures, for which purpose the height of the print head and / or a printing table can be adjusted so that several layers of material can be produced by screen printing. Through an automated exchange of the printing screens, different three-dimensional structures are produced in a simple, fully automated manner.
- a plurality of screen magazines are present. This increases the number of print screens that can be stored and increases the variance in the production of, in particular, three-dimensional print structures. All screen magazines are expediently accessible by the transport device.
- At least one of the sieve magazines or the at least one sieve magazine has a conditioning device which is designed to create a climate in the sieve magazine generate and maintain, which prevents drying of printing mass remaining on a printing screen.
- the conditioning device ensures that printing screens that have been in the screen magazine for a long time and still have residues of printing material can be reused without first having to be cleaned and completely refilled with printing material. This reduces material consumption and shortens processing times.
- the conditioning device preferably has at least one air humidifier and / or dehumidifier, by means of which the air located in the sieve magazine can be moistened or dehumidified in order to set an optimal climate in the sieve magazine for the respective pressure mass.
- a plurality of sieve magazines can each have a conditioning device, the conditioning devices then being designed differently or identically, but can be operated differently. In this way it can be achieved that an optimal climate for the printing screens located there can be set in each screen magazine.
- printing screens that are used for printing with a first material are then stored in a first screen magazine, and printing screens that are used with a second material are stored in a second screen magazine, so that an optimal climate setting is possible.
- the conditioning device has at least one cooling device and / or heating device. This also helps to prevent drying out and to ensure that the remaining printing compound is reused on the printing screens regardless of the ambient conditions.
- at least one sieve magazine is divided into at least two sections which can be conditioned differently by the conditioning device. As a result, different climates can be set in a screen magazine, which are selected in particular as a function of different printing masses. Printing masses made of materials such as ceramics, metals, polymers, biomaterials, alloys, composite materials or other printable material combinations can be provided.
- At least one sieve magazine has at least one closing element, which can be displaced for releasing or closing a housing housing the sieve bearings.
- the sieve magazine thus has a housing that holds the sieve housed and is particularly completely closable by a closing element. This simplifies maintaining a climate or conditioning in the sieve magazine, since the set climate can be maintained longer.
- An actuator is expediently assigned to the closing element, which automates the closing or releasing of the screen bearing.
- the transport device is designed to actuate the closing element.
- At least one sieve magazine has at least one pushing device for advancing a selected pressure sieve from one of the sieve bearings.
- a pressure screen can be advanced from a screen store or a screen store by the sliding device, so that the screen can be more easily gripped by the transport device and brought to the screen removal station or the use station or to a treatment station.
- the sliding device is in particular designed to advance the printing screen to such an extent that it projects beyond the housing of the screen magazine.
- the housing has a removal opening, with which the closing element is assigned. The sliding device is assigned to the removal opening in such a way that it can advance a pressure screen associated with the removal opening from the removal opening on the housing, so that it can be gripped by the transport device.
- the height of the screen bearings in the screen magazine is preferably adjustable.
- a lifting device is preferably present in the sieve magazine, by means of which the sieve bearings can be raised or lowered in order to assign a selected pressure sieve to the removal opening or to assign an empty sieve bearing to the extraction opening so that it can be loaded with a pressure sieve.
- At least one treatment station is designed as a pressure screen cleaning station.
- the printing screen cleaning station preferably has cleaning agents, by means of which a printing screen can be completely cleaned of any pressure mass remaining thereon. If, for example, it is known that a certain printing screen no longer has to be used for a longer period of time and there is a risk that aging of the printing mass remaining on the printing screen is to be feared due to the long period of time, this will be the case Printing screen fed through the transport device to the screen cleaning station, cleaned and stored in the screen magazine.
- At least one treatment station is designed as a printing screen filling station, which serves to fill a printing screen with a desired pressure mass before the printing screen is fed to the printing device.
- a printing screen filling station serves to fill a printing screen with a desired pressure mass before the printing screen is fed to the printing device.
- the printing screen filling station has tanks for storing different materials for printing on the printing screens.
- An intermediate step, such as the manual filling of a printing screen can thus be dispensed with and a mechanism in the printing device itself, which otherwise carries out the filling of a printing screen, can be omitted, as a result of which the printing device is space-saving, compact and also inexpensive to implement.
- At least one treatment station is a control station.
- the control station is in particular designed to measure a printing screen and to compare a structure / pattern predetermined by the printing screen with a target pattern in order to detect damage to the printing screen. If damage is detected, the printing screen is no longer placed back in the screen magazine, but is taken out of service.
- the control station preferably has a camera device for recording the print pattern or the structure, and a memory in which the target patterns of the available print screens are stored, in order to easily damage and / or a condition of the respective print screen by comparison to capture.
- the invention relates to a screen magazine for storing printing screens for a printing device, which has at least one conditioning device for setting or maintaining a climate in the screen magazine, and in particular is designed as described above.
- Figure 1 shows a simplified side view of a printing system 1, which has a printing device 2, a screen magazine 3 and a transport device 4.
- the printing device 2 has a printing table 5 which can be adjusted in height by a lifting device 6, as indicated by a double arrow 7.
- a print head 8, which has a doctor device 9, is assigned to the printing table 5.
- the doctor blade device 9 has a screen holder 10, in which a printing screen 11 can be arranged.
- the screen receptacle 10 is designed, for example, as a plug-in receptacle into which the printing screen 11 can be inserted, in particular inserted laterally or horizontally, as in FIG Figure 1 shown.
- the screen holder 10 is designed so that the printing screen 11 can be inserted into it.
- the screen holder 10 optionally has controllable clamping elements 12, by means of which the printing screen 11 can be clamped in the screen holder 10, so that the orientation and position of the printing screen 11 do not change during a printing process in which the squeegee of the doctor device 9 is moved over the printing screen 11 changed.
- the sieve magazine 3 has a housing 13 and in the present case is arranged at a distance from the printing device 2.
- a plurality of sieve bearings 14 are arranged one above the other or stacked one above the other in the housing 13.
- the screen bearings 14 are designed, for example, like the screen holder 10 and optionally also have the clamping elements 12.
- a pressure screen 11 can be arranged in each screen store 14.
- the housing 13 is essentially closed, but has a removal opening 15 on a side facing the printing device 2, through which a pressure screen 11 can be taken into or out of the housing 13.
- the transport device 4 is designed to move the printing screens 11. According to the present exemplary embodiment, this has a multi-articulated transport arm 16 which carries a gripper 17 at its free end.
- the gripper 17 is, for example, designed to operate pneumatically or mechanically in order to grip a single pressure screen 11.
- the transport device 4 is arranged between the printing device 2 and the screen magazine 3 in such a way that the transport arm 16 can reach both a printing screen 11 assigned to the removal opening 15 and a printing screen 11 stored in the screen receptacle 10.
- the removal opening 15 extends almost over the entire height of the sieve magazine 3, the transport arm 16 being designed such that it can reach each sieve bearing 14 or the pressure sieve located therein.
- the transport device 4 is optionally equipped with its own lifting device 18 in order to increase the freedom of movement of the gripper 17. Together with the screen magazine 3, the transport device 4 forms a screen preparation system 25 for the printing device 2.
- the function of the advantageous printing system 1 is as follows.
- the transport device 4 is first activated to remove a specific printing screen 11 from the screen magazine 3 and to feed it to the screen holder 10.
- the printing screen 11 is locked in the screen holder 10 by means of the clamping means 12.
- the printing screen 11 is then acted upon by a printing compound, in particular printing paste, made of a selected material and a doctor blade of the doctor device 9 is pushed over the printing screen 11, so that the printing compound is printed through the printing screen 11 onto the printing table.
- the printing compound is applied directly to the printing table 5, or to a substrate 19 arranged on the printing table 5, which can be designed, for example, as a carrier substrate, or also as a printed circuit board, wafer or the like.
- the printing screen 11 has screen openings in some areas which correspond to the desired first layer of the structure to be printed. Many such structures can be incorporated into the printing screen 11, so that a plurality of components or structural elements / structures can also be produced side by side in one printing process on the substrate 19 and / or the printing table 5.
- the printing table 7 is moved downward, for example, by the lifting device 6 and a further printing operation is carried out, in which the same printing screen 11 is used to produce a further pressure position which has the same structure as the first pressure position .
- one of the other printing screens 11 is used instead of the same printing screen 11.
- the transport arm 16 moves the printing screen 11 located in the screen receptacle 10 into the screen magazine 3, namely into a screen storage 14 that is free there.
- the transport arm 16 then removes another screen 11 from another pressure bearing 14 and feeds it to the screen mounting 10 of the printing device 2 .
- a print position is then generated which differs in shape from the previous print position. With this principle you can several print layers are produced on top of each other, which differ from each other, whereby complex three-dimensional structures can also be produced.
- the printing table 5 is lowered a little, or alternatively the printing head 9 is raised a little.
- the screen bearings 14 are arranged fixedly in the housing 13, according to a further exemplary embodiment which is shown in Figure 2 is shown in a simplified representation, it is provided that the screen bearings 14 can be moved in height in the housing 13, as shown by a double arrow 20.
- the screen bearings 14 can be displaced along vertical rails 22 by means of a lifting device 21.
- the removal opening 15 of the housing 13 is arranged approximately in the center of the housing 13 and is narrow enough that only a pressure screen 11 can be removed from the housing 13 or inserted into the housing 13 by the transport arm 16.
- a specific printing screen 11 is to be removed from the screen magazine 3
- the screen bearings 14 are first moved or shifted vertically such that this printing screen 11 is assigned to the removal opening 15 and can be removed by the transport arm 16.
- the essentially closed design of the housing 13 of the screen magazine 3 has the advantage that there is a climate in the screen magazine 3 which improves the provision of the pressure screens 11 in the screen magazine 3.
- a conditioning device 23 is also arranged in the sieve magazine 3, which has, for example, a cooling device or heating device, an air humidifier and / or a dehumidifier in order to influence the climate in the sieve magazine 3.
- the climate is influenced in such a way that residues of the printing compound remaining on the respective printing screen 11 are kept flowable. This prevents drying out.
- the transport device 4 can be completely integrated into the printing device 2 or also completely into the sieve magazine 3.
- the transport device is partly formed by the printing device and partly by the sieve magazine 3.
- the sieve magazine 3 has, for example, a sliding device 24, as shown in FIG Figure 2 is shown by way of example.

- the transport arm 16 is formed, for example, on the printing device 2.
- the removal opening can optionally be closed by a movable closing element 33.
- the sliding device 24 is designed such that it pushes the pressure screen completely through the removal opening 15 into the screen receptacle 10. If the removal opening 15 and sieve holder 10 are aligned with one another, this can be implemented simply and inexpensively.
- the printing device 2 then expediently has a corresponding sliding device which is designed to push the printing screen 11 back into the screen magazine and the screen bearing associated with the removal opening 15 after a printing process has been carried out.
- FIG 3 shows a simplified plan view of advantageous screen preparation systems 25, of which in Figure 1 only the sieve magazine 3 and the transport device 4 are shown.

- the treatment station 26 is designed as a screen cleaning station. This is designed to clean a printing screen provided by the transport device 4 and thereby to remove all residues of printing material from the printing screen. After the cleaning has taken place, the affected printing screen is returned, for example, by the transport device 4 into one of the screen magazines 3 to 3_3.
- the treatment station 27 in the present case is a screen filling station which is designed to fill a printing screen fed to it with at least one material or a material of a printing material. This results in a centralized filling of the printing screens 11 by the screen filling station 27.
- the latter is designed to provide different printing compositions or materials, so that pre-filled printing screens with different printing compositions or printing materials can be provided by the screen preparation system 25.
- the transport device 4 ensures the transport of the respective Printing screen to the screen filling station 27 and from this, for example, to the screen use station 31.
- the screen filling station 27 can be supplied with cleaned printing screens as well as printing screens which have already been filled with a material and thus possibly have pressure residues.
- An identifier / identification feature arranged on the printing screens ensures that a material that is different from the previously applied material is received on a printing screen that has already been filled and has not previously been cleaned.
- the treatment station 28 in the present case is a control station which is in particular designed to measure a pressure screen 11 fed to it and to check it for damage. This can ensure that only properly designed and functioning printing screens are present in the printing screen preparation system 25 and are output by the screen use station 31.
- the treatment stations 26, 27 and 28 preferably each have a sieve bearing, on which the sieve bearing 14 corresponds or the sieve holder 10, for holding a pressure sieve in each case in order to carry out the respectively intended treatment.

Description
Die Erfindung betrifft ein Siebbereitstellungssystem insbesondere für eine Druckvorrichtung, insbesondere 3D-Siebdruckvorrichtung, die eine Siebaufnahme für ein Drucksieb sowie eine dem Drucksieb zugeordnete Rakeleinrichtung aufweist.The invention relates to a screen preparation system, in particular for a printing device, in particular a 3D screen printing device, which has a screen holder for a printing screen and a doctor device assigned to the printing screen.
Druckvorrichtungen, welche mittels einer Rakeleinrichtung und eines Drucksiebs, auch als Druckmaske bezeichnet, eine Materialschicht mit einer durch das Drucksieb bestimmte Struktur auf ein Substrat auftragen, sind aus dem Stand der Technik bekannt. Beispielsweise zur Herstellung von Leiterplatten ist es bekannt, auf ein Leiterplattensubstrat elektrisch leitfähige Strukturen mittels einer derartigen Druckvorrichtung aufzudrucken. Die Verwendung des Drucksiebs hat den Vorteil, dass auf einfache Art und Weise die Strukturen mehrfach auf mehrere Substrate oder auch auf ein Substrat mehrfach aufgetragen werden können. Dabei stehen Zeit und Kostenvorteile im Vordergrund. Eine Alternative dazu ist es, Leiterbahnstrukturen durch eine Spritzdüse gezielt aufzutragen, wobei dies zeittechnisch und kostentechnisch nachteilig gegenüber der zuvor genannten Druckvorrichtung ist.Printing devices which use a doctor blade device and a printing screen, also referred to as a printing mask, to apply a material layer with a structure determined by the printing screen to a substrate are known from the prior art. For example, for the production of printed circuit boards, it is known to print electrically conductive structures onto a printed circuit board substrate by means of such a printing device. The use of the printing screen has the advantage that the structures can be applied multiple times to multiple substrates or to one substrate multiple times in a simple manner. The focus is on time and cost advantages. An alternative to this is to apply conductor track structures in a targeted manner by means of a spray nozzle, this being disadvantageous in terms of time and cost in comparison with the previously mentioned printing device.
Nachteilig bei Siebdruckvorrichtungen ist es, dass für die Erzeugung unterschiedlicher Strukturen unterschiedliche Drucksiebe verwendet werden müssen. Dies bedeutet für den Benutzer einen erhöhten Aufwand, weil er das Drucksieb austauschen, reinigen und durch ein neues Drucksieb, das erneut befüllt werden muss, ersetzen muss. Dokument
Der Erfindung liegt die Aufgabe zugrunde, ein Siebbereitstellungssystem zu schaffen, welches die Bearbeitungszeit verringert, die Materialausnutzung verbessert und einen sicheren Druckvorgang gewährleistet.The invention has for its object to provide a screen preparation system that reduces processing time, improves material utilization and ensures a safe printing process.
Die der Erfindung zugrundeliegende Aufgabe wird durch die Bereitstellungseinrichtung mit den Merkmalen des Anspruchs 1 gelöst. Diese hat den Vorteil, dass ein Drucksieb für einen Druckvorgang, insbesondere für einen Druck von dreidimensional geformten Strukturen automatisiert zur Verfügung gestellt wird, und darüber hinaus vorbereitende und nachbereitende Schritte erleichtert und zum Teil gänzlich vermeidet werden. Dadurch kann der Durchsatz der Druckvorrichtung erhöht und die Belastung des Benutzers reduziert werden, wobei das Druckergebnis beziehungsweise die Druckqualität dadurch nicht nachteilig beeinflusst werden.The object on which the invention is based is achieved by the provision device having the features of
Das erfindungsgemäße Siebbereitstellungssystem zeichnet sich dadurch aus, dass es eine Transporteinrichtung zum Transportieren jeweils eines Drucksiebs aufweist, sowie zumindest ein Siebmagazin, das eine Vielzahl von Sieblagern zur Aufnahme jeweils eines Drucksiebs aufweist, und insbesondere zumindest eine Behandlungsstation zum Behandeln der Drucksiebe, wobei die Transporteinrichtung dazu ausgebildet ist, das zumindest eine Siebmagazin und insbesondere die zumindest eine Behandlungsstation mit Drucksieben zu bedienen. Das Siebbereitstellungssystem weist also ein Siebmagazin zur Aufnahme einer Vielzahl von Drucksieben auf. Damit ist es möglich, eine Vielzahl gleicher und/oder unterschiedlicher Drucksiebe in dem Siebmagazin zu lagern, wenn sie gerade für einen Druckvorgang nicht benötigt werden. Durch diese zentralisierte Aufbewahrung ist eine einfache Handhabung einer Vielzahl von Drucksieben sicher gewährleistet. Vorzugsweise weisen die Drucksiebe Marker auf, und das Siebmagazin eine Erkennungseinrichtung, um die Anwesenheit und Position von Drucksieben in dem Siebmagazin zu erfassen, sodass bei Bedarf in einfacher Art und Weise das gewünschte Drucksieb aus dem Siebmagazin entfernt werden kann. Durch die zumindest eine Behandlungsstation können vorhandene Drucksiebe insbesondere vor- oder nachbehandelt werden, um den Druckvorgang einer Druckvorrichtung effizient zu gestalten. Insbesondere ist die Behandlungsstation dazu ausgebildet, ansonsten dem Benutzer obliegende Tätigkeiten zu übernehmen und dadurch einen Druckvorgang zu vereinfachen. Weil die Transporteinrichtung sowohl die Behandlungsstation als auch das Siebmagazin erreicht beziehungsweise bedient, können die Drucksiebe mittels der Transporteinrichtung automatisiert von dem Siebmagazin zu der Behandlungsstation und umgekehrt verbracht werden, sodass die Vor- oder Nachbehandlung eines Drucksiebs automatisiert erfolgt. Darüber hinaus hat die Aufbewahrung im Siebmagazin den Vorteil, dass eine Reinigung eines Drucksiebs nach einem durchgeführten Druckvorgang nicht unbedingt erfolgen muss. Stattdessen wird das Drucksieb in dem Siebmagazin mit darauf verbliebenen Resten von Druckmasse gelagert, bis es wieder für einen Druckvorgang mit der gleichen Druckmasse benötigt wird. Dadurch kann auf einen Reinigungsschritt auch ganz verzichtet werden.The screen preparation system according to the invention is characterized in that it has a transport device for transporting a pressure screen in each case, as well as at least one screen magazine which has a multiplicity of screen bearings for receiving a pressure screen in each case, and in particular at least one treatment station for treating the pressure screens, the transport device for this purpose is designed to operate the at least one sieve magazine and in particular the at least one treatment station with pressure sieves. The screen preparation system thus has a screen magazine for holding a large number of printing screens. This makes it possible to store a large number of identical and / or different printing screens in the screen magazine when they are not required for a printing process. This centralized storage ensures easy handling of a large number of printing screens. The printing screens preferably have markers, and the screen magazine has a detection device in order to detect the presence and position of printing screens in the screen magazine, so that the desired printing screen can be removed from the screen magazine in a simple manner if necessary. Using the at least one treatment station, existing printing screens can in particular be pretreated or post-treated in order to make the printing process of a printing device efficient. In particular, the treatment station is designed to take over tasks that are otherwise incumbent on the user and thereby to simplify a printing process. Because the transport device reaches and operates both the treatment station and the screen magazine, the printing screens can be moved automatically from the screen magazine to the treatment station and vice versa by means of the transport device, so that the pre-treatment or post-treatment of a print screen takes place automatically. In addition, storage in the screen magazine has the advantage that it is not absolutely necessary to clean a printing screen after a printing process has been carried out. Instead, the printing screen is stored in the screen magazine with remnants of printing mass remaining on it until it is required again for a printing process with the same printing mass. This means that a cleaning step can also be dispensed with entirely.
Gemäß einer bevorzugten Weiterbildung der Erfindung ist vorgesehen, dass das Siebbereitstellungssystem eine von der Transporteinrichtung mit den Drucksieben bedienbare Siebnutzungsstation aufweist. Unter der Siebnutzungsstation wird in diesem Zusammenhang eine Station verstanden, in welcher das Sieb seinem eigentlichen Zweck zugeführt wird. Damit muss der Benutzer ein Sieb nicht selbst aus dem Siebmagazin entnehmen und beispielsweise einer Druckvorrichtung zuführen. Vielmehr wird ein Drucksieb dem Benutzer und/oder einer Druckvorrichtung das Drucksieb automatisiert zur Verfügung gestellt. Alternativ ist das Siebmagazin dazu ausgebildet, dass der Benutzer ein gewünschtes Drucksieb dort selbst entnimmt. Dazu kann das Siebmagazin beispielsweise zweiseitig offen sein, wobei an einer Seite die Transporteinrichtung Zugriff zu den Drucksieben hat, und von der anderen Seite der Benutzer.According to a preferred development of the invention, it is provided that the screen preparation system has a screen use station that can be operated by the transport device with the printing screens. In this context, under the screen usage station understood a station in which the sieve is used for its actual purpose. This means that the user does not have to remove a screen from the screen magazine himself and feed it to a printing device, for example. Rather, a printing screen is automatically made available to the user and / or a printing device. Alternatively, the sieve magazine is designed so that the user himself can remove a desired pressure sieve there. For this purpose, the screen magazine can be open on two sides, for example, the transport device having access to the printing screens on one side and the user on the other side.
Gemäß einer bevorzugten Ausführungsform der Erfindung ist die Siebnutzungsstation eine Siebentnahmestation für den Benutzer. An der Entnahmestation wird dem Benutzer somit das jeweils ausgewählte Drucksieb zur Verfügung gestellt, sodass dieser nicht selbst in dem Magazin nach dem passenden Drucksieb suchen muss. Insbesondere weist die Entnahmestation ein Sieblager auf, in welches die Transporteinrichtung das ausgewählte Drucksieb zur Entnahme ablegen kann.According to a preferred embodiment of the invention, the screen use station is a screen removal station for the user. The user selected printing screen is thus made available to the user at the removal station, so that the user does not have to search for the suitable printing screen in the magazine himself. In particular, the removal station has a screen storage in which the transport device can place the selected printing screen for removal.
Gemäß einer alternativen Ausführungsform der Erfindung ist bevorzugt vorgesehen, dass die Siebnutzungsstation eine Druckvorrichtung ist. Damit ist die Transporteinrichtung dazu ausgebildet, ein ausgewähltes Drucksieb direkt einer Druckvorrichtung für die Durchführung eines Druckvorgangs zuzuführen. Insbesondere ist die Transporteinrichtung dazu ausgebildet, das ausgewählte Drucksieb in die Siebaufnahme der Druckvorrichtung einzuführen beziehungsweise dort anzuordnen, sodass in Folge ein Druckvorgang automatisiert durchgeführt werden kann. Insbesondere ist die Druckvorrichtung für das Drucken dreidimensional geformter Strukturen ausgebildet, wozu der Druckkopf und/oder ein Drucktisch in der Höhe verstellbar sind, sodass mehrere Lagen von Material durch den Siebdruck erzeugt werden können. Durch einen automatisierten Austausch der Drucksiebe werden dabei unterschiedliche dreidimensionale Strukturen in einfacher Art und Weise vollautomatisiert hergestellt.According to an alternative embodiment of the invention, it is preferably provided that the screen use station is a printing device. The transport device is thus designed to feed a selected printing screen directly to a printing device for carrying out a printing process. In particular, the transport device is designed to insert the selected printing screen into the screen holder of the printing device or to arrange it there, so that a printing process can subsequently be carried out automatically. In particular, the printing device is designed for printing three-dimensionally shaped structures, for which purpose the height of the print head and / or a printing table can be adjusted so that several layers of material can be produced by screen printing. Through an automated exchange of the printing screens, different three-dimensional structures are produced in a simple, fully automated manner.
Gemäß einer bevorzugten Weiterbildung der Erfindung ist vorgesehen, dass mehrere Siebmagazine vorhanden sind. Dadurch wird die Anzahl der lagerbaren Drucksiebe erhöht und die Varianz bei der Herstellung insbesondere dreidimensionaler Druckstrukturen vergrößert. Zweckmäßigerweise sind alle Siebmagazine durch die Transporteinrichtung erreichbar.According to a preferred development of the invention, it is provided that a plurality of screen magazines are present. This increases the number of print screens that can be stored and increases the variance in the production of, in particular, three-dimensional print structures. All screen magazines are expediently accessible by the transport device.
Erfindungsgemäß weist zumindest eines der Siebmagazine oder das zumindest eine Siebmagazin eine Konditionierungseinrichtung auf, die dazu ausgebildet ist, in dem Siebmagazin ein Klima zu erzeugen und aufrecht zu erhalten, welches ein Eintrocknen von auf einem Drucksieb verbliebener Druckmasse verhindert. Durch die Konditionierungseinrichtung wird erreicht, dass sichergestellt ist, dass Drucksiebe, die sich auch längere Zeit im Siebmagazin befinden und noch Reste von Druckmasse aufweisen, wiederverwendet werden können, ohne dass sie zuerst gereinigt und vollständig mit Druckmasse erneut befüllt werden müssen. Dadurch werden sowohl der Materialverbrauch reduziert als auch die Bearbeitungszeit verkürzt.According to the invention, at least one of the sieve magazines or the at least one sieve magazine has a conditioning device which is designed to create a climate in the sieve magazine generate and maintain, which prevents drying of printing mass remaining on a printing screen. The conditioning device ensures that printing screens that have been in the screen magazine for a long time and still have residues of printing material can be reused without first having to be cleaned and completely refilled with printing material. This reduces material consumption and shortens processing times.
Bevorzugt weist die Konditionierungseinrichtung zumindest einen Luftbefeuchter und/oder Entfeuchter auf, mittels dessen die in dem Siebmagazin befindliche Luft angefeuchtet beziehungsweise entfeuchtet werden kann, um ein für die jeweilige Druckmasse optimales Klima in dem Siebmagazin einzustellen. Sind mehrere Siebmagazine vorhanden, so können auch mehrere Siebmagazine jeweils eine Konditionierungseinrichtung aufweisen, wobei die Konditionierungseinrichtungen dann unterschiedlich oder gleich ausgebildet, aber unterschiedlich betrieben werden können. Dadurch kann erreicht werden, dass in jedem Siebmagazin ein für die dort befindlichen Drucksiebe optimales Klima eingestellt werden kann. Insbesondere werden dann Drucksiebe, die zum Bedrucken mit einem ersten Material verwendet werden, in einem ersten Siebmagazin, und Drucksiebe, die mit einem zweiten Material verwendet werden, in einem zweiten Siebmagazin gelagert, sodass eine optimale Klimaeinstellung möglich ist.The conditioning device preferably has at least one air humidifier and / or dehumidifier, by means of which the air located in the sieve magazine can be moistened or dehumidified in order to set an optimal climate in the sieve magazine for the respective pressure mass. If a plurality of sieve magazines are present, then a plurality of sieve magazines can each have a conditioning device, the conditioning devices then being designed differently or identically, but can be operated differently. In this way it can be achieved that an optimal climate for the printing screens located there can be set in each screen magazine. In particular, printing screens that are used for printing with a first material are then stored in a first screen magazine, and printing screens that are used with a second material are stored in a second screen magazine, so that an optimal climate setting is possible.
Weiterhin ist bevorzugt vorgesehen, dass die Konditionierungseinrichtung zumindest eine Kühleinrichtung und/oder Heizeinrichtung aufweist. Auch diese hilft dabei, das Eintrocknen zu vermeiden und eine Wiederverwendung zurückgebliebener Druckmasse auf den Drucksieben unabhängig von Umgebungsbedingungen zu gewährleisten. Gemäß einer weiteren Ausführungsform der Erfindung ist bevorzugt vorgesehen, dass zumindest ein Siebmagazin in zumindest zwei Abschnitte unterteilt ist, die unterschiedlich durch die Konditionierungseinrichtung konditionierbar sind. Dadurch können in einem Siebmagazin unterschiedliche Klimata eingestellt werden, die insbesondere in Abhängigkeit von unterschiedlichen Druckmassen gewählt werden. So können Druckmassen aus Materialien wie Keramik, Metalle, Polymere, Biomaterialien, Legierungen, Kompositmaterialien oder andere druckbare Materialkombinationen vorgesehen sein.Furthermore, it is preferably provided that the conditioning device has at least one cooling device and / or heating device. This also helps to prevent drying out and to ensure that the remaining printing compound is reused on the printing screens regardless of the ambient conditions. According to a further embodiment of the invention, it is preferably provided that at least one sieve magazine is divided into at least two sections which can be conditioned differently by the conditioning device. As a result, different climates can be set in a screen magazine, which are selected in particular as a function of different printing masses. Printing masses made of materials such as ceramics, metals, polymers, biomaterials, alloys, composite materials or other printable material combinations can be provided.
Weiterhin ist erfindungsgemäß vorgesehen, dass zumindest ein Siebmagazin zumindest ein Schließelement aufweist, das zum Freigeben oder Verschließen eines die Sieblager einhausenden Gehäuses verlagerbar ist. Das Siebmagazin weist also ein Gehäuse auf, das die Sieblager einhaust und ist durch ein Schließelement insbesondere vollständig verschließbar. Dadurch wird das Aufrechterhalten eines Klimas beziehungsweise einer Konditionierung in dem Siebmagazin vereinfacht, da das eingestellte Klima länger aufrechterhalten bleiben kann. Zweckmäßigerweise ist dem Schließelement ein Aktuator zugeordnet, welcher das Verschließen oder Freigeben des Sieblagers automatisiert. Alternativ ist die Transporteinrichtung dazu ausgebildet, das Schließelement zu betätigen.Furthermore, it is provided according to the invention that at least one sieve magazine has at least one closing element, which can be displaced for releasing or closing a housing housing the sieve bearings. The sieve magazine thus has a housing that holds the sieve housed and is particularly completely closable by a closing element. This simplifies maintaining a climate or conditioning in the sieve magazine, since the set climate can be maintained longer. An actuator is expediently assigned to the closing element, which automates the closing or releasing of the screen bearing. Alternatively, the transport device is designed to actuate the closing element.
Weiterhin ist bevorzugt vorgesehen, dass zumindest ein Siebmagazin zumindest eine Schiebeeinrichtung zum Vorschieben eines ausgewählten Drucksiebs aus einem der Sieblager aufweist. Durch die Schiebeeinrichtung ist ein Drucksieb aus einem Sieblager oder ein Sieblager vorschiebbar, sodass das Drucksieb einfacher von der Transporteinrichtung gegriffen und zu der Siebentnahmestation beziehungsweise der Nutzungsstation oder zu einer Behandlungsstation gebracht werden kann. Dabei ist die Schiebeeinrichtung insbesondere dazu ausgebildet, das Drucksieb derart weit vorzuschieben, dass es über das Gehäuse des Siebmagazins vorsteht. Insbesondere weist das Gehäuse eine Entnahmeöffnung auf, welcher das Schließelement zugeordnet ist. Die Schiebeeinrichtung ist der Entnahmeöffnung derart zugeordnet, dass sie ein der Entnahmeöffnung zugeordnetes Drucksieb aus der Entnahmeöffnung an dem Gehäuse ein Stück weit vorschieben kann, sodass es von der Transporteinrichtung greifbar ist. Um ein Drucksieb der Entnahmeöffnung in dem Siebmagazin zuzuführen, sind bevorzugt die Sieblager in dem Siebmagazin in der Höhe verstellbar. Hierzu ist bevorzugt eine Hubeinrichtung in dem Siebmagazin vorhanden, mittels welcher die Sieblager angehoben oder gesenkt werden können, um ein ausgewähltes Drucksieb der Entnahmeöffnung zuzuordnen oder ein leeres Sieblager der Entnahmeöffnung zuzuordnen, sodass es mit einem Drucksieb belegt werden kann.Furthermore, it is preferably provided that at least one sieve magazine has at least one pushing device for advancing a selected pressure sieve from one of the sieve bearings. A pressure screen can be advanced from a screen store or a screen store by the sliding device, so that the screen can be more easily gripped by the transport device and brought to the screen removal station or the use station or to a treatment station. The sliding device is in particular designed to advance the printing screen to such an extent that it projects beyond the housing of the screen magazine. In particular, the housing has a removal opening, with which the closing element is assigned. The sliding device is assigned to the removal opening in such a way that it can advance a pressure screen associated with the removal opening from the removal opening on the housing, so that it can be gripped by the transport device. In order to supply a pressure screen to the removal opening in the screen magazine, the height of the screen bearings in the screen magazine is preferably adjustable. For this purpose, a lifting device is preferably present in the sieve magazine, by means of which the sieve bearings can be raised or lowered in order to assign a selected pressure sieve to the removal opening or to assign an empty sieve bearing to the extraction opening so that it can be loaded with a pressure sieve.
Gemäß einer bevorzugten Weiterbildung der Erfindung sind mehrere Behandlungsstationen vorhanden. Diese werden alle von der Transporteinrichtung bedient. Dadurch können unterschiedliche Behandlungsschritte durch das Siebbereitstellungssystem vorgenommen werden.According to a preferred development of the invention, there are several treatment stations. These are all served by the transport device. As a result, different treatment steps can be carried out by the screen preparation system.
Insbesondere ist zumindest eine Behandlungsstation als Drucksiebreinigungsstation ausgebildet. Dazu weist die Drucksiebreinigungsstation bevorzugt Reinigungsmittel auf, mittels welcher ein Drucksieb vollständig von gegebenenfalls darauf verbliebener Druckmasse bereinigt werden kann. Ist beispielsweise bekannt, dass ein bestimmtes Drucksieb für einen längeren Zeitraum nicht mehr benutzt werden muss, und besteht die Gefahr, dass aufgrund des langen Zeitraums eine Alterung der auf dem Drucksieb verbliebenen Druckmasse zu befürchten ist, so wird das Drucksieb durch die Transporteinrichtung der Siebreinigungsstation zugeführt, gereinigt und in dem Siebmagazin abgelegt.In particular, at least one treatment station is designed as a pressure screen cleaning station. For this purpose, the printing screen cleaning station preferably has cleaning agents, by means of which a printing screen can be completely cleaned of any pressure mass remaining thereon. If, for example, it is known that a certain printing screen no longer has to be used for a longer period of time and there is a risk that aging of the printing mass remaining on the printing screen is to be feared due to the long period of time, this will be the case Printing screen fed through the transport device to the screen cleaning station, cleaned and stored in the screen magazine.
Gemäß einer bevorzugten Ausführungsform der Erfindung ist weiterhin vorgesehen, dass zumindest eine Behandlungsstation als Drucksiebbefüllungsstation ausgebildet ist, die dazu dient, ein Drucksieb mit einer gewünschten Druckmasse zu befüllen, bevor das Drucksieb der Druckvorrichtung zugeführt wird. Damit wird erreicht, dass die Druckmasse außerhalb der Druckvorrichtung auf das Drucksieb ausgegeben wird. Dadurch ist auch das Aufbringen unterschiedlicher Druckmassen auf die Drucksiebe sicher gewährleistet. Insbesondere weist die Drucksiebbefüllungsstation Tanks zur Aufbewahrung unterschiedlicher Materialien zum Bedrucken der Drucksiebe auf. Auf einen Zwischenschritt, wie das manuelle Befüllen eines Drucksiebs, kann damit verzichtet werden und auch ein Mechanismus in der Druckvorrichtung selbst, welche ansonsten das Befüllen eines Drucksiebs vornimmt, kann entfallen, wodurch die Druckvorrichtung bauraumsparend, kompakt und auch kostengünstig realisierbar ist.According to a preferred embodiment of the invention, it is further provided that at least one treatment station is designed as a printing screen filling station, which serves to fill a printing screen with a desired pressure mass before the printing screen is fed to the printing device. This ensures that the printing compound is output onto the printing screen outside the printing device. As a result, the application of different printing masses to the printing screens is also guaranteed. In particular, the printing screen filling station has tanks for storing different materials for printing on the printing screens. An intermediate step, such as the manual filling of a printing screen, can thus be dispensed with and a mechanism in the printing device itself, which otherwise carries out the filling of a printing screen, can be omitted, as a result of which the printing device is space-saving, compact and also inexpensive to implement.
Weiterhin ist bevorzugt vorgesehen, dass zumindest eine Behandlungsstation eine Kontrollstation ist. Die Kontrollstation ist insbesondere dazu ausgebildet, ein Drucksieb zu vermessen und ein durch das Drucksieb vorgegebenes Struktur/Muster mit einem Soll-Muster zu vergleichen, um Beschädigungen des Drucksiebs zu erkennen. Wird eine Beschädigung erkannt, wird das Drucksieb nicht mehr zurück in das Siebmagazin gelegt, sondern ausgemustert. Die Kontrollstation weist dazu bevorzugt eine Kameraeinrichtung zum Erfassen des Druckmusters beziehungsweise der Struktur auf, sowie ein Speicher, in welchem die Soll-Muster der zur Verfügung gestellten Drucksiebe hinterlegt sind, um durch einen Vergleich eine Beschädigung und/oder einen Zustand des jeweiligen Drucksiebs einfach zu erfassen.Furthermore, it is preferably provided that at least one treatment station is a control station. The control station is in particular designed to measure a printing screen and to compare a structure / pattern predetermined by the printing screen with a target pattern in order to detect damage to the printing screen. If damage is detected, the printing screen is no longer placed back in the screen magazine, but is taken out of service. For this purpose, the control station preferably has a camera device for recording the print pattern or the structure, and a memory in which the target patterns of the available print screens are stored, in order to easily damage and / or a condition of the respective print screen by comparison to capture.
Weiterhin betrifft die Erfindung ein Siebmagazin zur Aufbewahrung von Drucksieben für eine Druckvorrichtung, das zumindest eine Konditionierungseinrichtung zum Einstellen oder Aufrechterhalten eines Klimas in dem Siebmagazin aufweist, und insbesondere wie zuvor beschrieben ausgebildet ist.Furthermore, the invention relates to a screen magazine for storing printing screens for a printing device, which has at least one conditioning device for setting or maintaining a climate in the screen magazine, and in particular is designed as described above.
Im Folgenden soll die Erfindung anhand der Zeichnung näher erläutert werden. Dazu zeigen

Die Druckvorrichtung 2 weist einen Drucktisch 5 auf, der durch eine Hubvorrichtung 6 in der Höhe verstellbar ist, wie durch einen Doppelpfeil 7 angezeigt. Dem Drucktisch 5 zugeordnet ist ein Druckkopf 8, der eine Rakeleinrichtung 9 aufweist. Zusätzlich zu einem hier nicht näher dargestellten Rakel weist die Rakeleinrichtung 9 eine Siebaufnahme 10 auf, in welcher ein Drucksieb 11 anordenbar ist. Die Siebaufnahme 10 ist dazu beispielsweise als Steckaufnahme ausgebildet, in welche das Drucksieb 11 eingesteckt, insbesondere seitlich beziehungsweise horizontal eingeschoben werden kann, wie in
Das Siebmagazin 3 weist ein Gehäuse 13 auf und ist vorliegend beabstandet zu der Druckvorrichtung 2 angeordnet. In dem Gehäuse 13 sind mehrere Sieblager 14 übereinanderliegend beziehungsweise übereinander gestapelt angeordnet. Die Sieblager 14 sind beispielsweise wie die Siebaufnahme 10 ausgebildet und weisen optional ebenfalls die Klemmelemente 12 auf. In jedem Sieblager 14 ist ein Drucksieb 11 anordenbar. Das Gehäuse 13 ist im Wesentlichen geschlossen ausgebildet, weist jedoch auf einer insbesondere der Druckvorrichtung 2 zugewandten Seite eine Entnahmeöffnung 15 auf, durch welche ein Drucksieb 11 in das Gehäuse 13 ein oder aus diesem herausgenommen werden kann.The
Zum Bewegen der Drucksiebe 11 ist die Transporteinrichtung 4 ausgebildet. Diese weist gemäß dem vorliegenden Ausführungsbeispiel einen mehrgelenkigen Transportarm 16 auf, der an seinem freien Ende einen Greifer 17 trägt. Der Greifer 17 ist beispielsweise pneumatisch oder mechanisch arbeitend ausgebildet, um ein einzelnes Drucksieb 11 zu greifen. Die Transporteinrichtung 4 ist zwischen der Druckvorrichtung 2 und dem Siebmagazin 3 derart angeordnet, dass der Transportarm 16 sowohl ein der Entnahmeöffnung 15 zugeordnetes Drucksieb 11 als auch ein in der Siebaufnahme 10 abgelegtes Drucksieb 11 erreichen kann. Gemäß dem vorliegenden Ausführungsbeispiel erstreckt sich die Entnahmeöffnung 15 nahezu über die gesamte Höhe des Siebmagazins 3, wobei der Transportarm 16 derart ausgebildet ist, dass er jedes Sieblager 14 beziehungsweise das darin befindliche Drucksieb erreichen kann. Optional ist dazu die Transporteinrichtung 4 mit einer eigenen Hubvorrichtung 18 ausgestattet, um die Bewegungsfreiheit des Greifers 17 zu erhöhen. Zusammen mit dem Siebmagazin 3 bildet die Transporteinrichtung 4 ein Siebbereitstellungssystem 25 für die Druckvorrichtung 2.The
Die Funktion des vorteilhaften Drucksystems 1 gestaltet sich wie folgt. Für das Drucken dreidimensional geformter Strukturen wird die Transporteinrichtung 4 zunächst dazu angesteuert, ein bestimmtes Drucksieb 11 aus dem Siebmagazin 3 zu entnehmen und der Siebaufnahme 10 zuzuführen. Das Drucksieb 11 wird in der Siebaufnahme 10 mittels der Klemmmittel 12 arretiert. Anschließend wird das Drucksieb 11 mit einer Druckmasse, insbesondere Druckpaste, aus einem ausgewählten Material beaufschlagt und ein Rakel der Rakeleinrichtung 9 über das Drucksieb 11 geschoben, sodass die Druckmasse durch das Drucksieb 11 hindurch auf den Drucktisch aufgedruckt wird. Dabei ist es denkbar, dass die Druckmasse direkt auf den Drucktisch 5 aufgetragen wird, oder auf ein auf dem Drucktisch 5 angeordnetes Substrat 19, das beispielsweise als Trägersubstrat, oder auch als Leiterplatte, Wafer oder dergleichen ausgebildet sein kann. Das Drucksieb 11 weist dazu bereichsweise Sieböffnungen auf, welche der gewünschten ersten Schicht der zu druckenden Struktur entsprechen. Dabei können viele derartiger Strukturen in das Drucksieb 11 eingearbeitet sein, sodass auch mehreren Bauteile beziehungsweise Strukturelemente/Strukturen gleichzeitig einem Druckvorgang auf dem Substrat 19 und/oder dem Drucktisch 5 nebeneinanderliegend hergestellt werden können.The function of the
Nachdem die erste Drucklage erzeugt wurde, wird der Drucktisch 7 beispielsweise nach unten durch die Hubeinrichtung 6 verfahren und ein weiterer Druckvorgang durchgeführt, bei welchem das gleiche Drucksieb 11 genutzt wird, um eine weitere Drucklage zu erzeugen, welche die gleiche Struktur wie die erste Drucklage aufweist. Optional wird anstelle des gleichen Drucksiebs 11 eines der anderen Drucksiebe 11 verwendet. Dazu verbringt der Transportarm 16 das in der Siebaufnahme 10 befindliche Drucksieb 11 in das Siebmagazin 3, nämlich in ein dort freies Sieblager 14. Anschließend entnimmt der Transportarm 16 ein anderes Sieb 11 aus einem anderen Drucklager 14 und führt dieses der Siebaufnahme 10 der Druckvorrichtung 2 zu. Bei einem darauffolgenden Druckvorgang wird dann beispielsweise eine Drucklage erzeugt, welche sich in ihrer Gestalt von der vorherigen Drucklage unterscheidet. Durch dieses Prinzip können mehrere Drucklagen übereinander hergestellt werden, die sich voneinander unterscheiden, wodurch auch komplexe dreidimensionale Strukturen hergestellt werden können. Nach jedem erfolgten Druckvorgang wird der Drucktisch 5 ein Stück weit gesenkt oder alternativ wird der Druckkopf 9 ein Stück weit angehoben.After the first pressure position has been generated, the printing table 7 is moved downward, for example, by the
Während gemäß dem Ausführungsbeispiel von
Soll ein bestimmtes Drucksieb 11 aus dem Siebmagazin 3 entnommen werden, so werden zunächst die Sieblager 14 derart vertikal bewegt beziehungsweise verschoben, dass dieses Drucksieb 11 der Entnahmeöffnung 15 zugeordnet ist und von dem Transportarm 16 entnommen werden kann. Die dadurch im Wesentlichen geschlossene Ausbildung des Gehäuses 13 des Siebmagazins 3 hat den Vorteil, dass in dem Siebmagazin 3 ein Klima besteht, welches die Vorhaltung der Drucksiebe 11 in dem Siebmagazin 3 verbessert. Optional ist in dem Siebmagazin 3 außerdem eine Konditionierungseinrichtung 23 angeordnet, welche beispielsweise eine Kühleinrichtung oder Heizeinrichtung, einen Luftbefeuchter und/oder einen Luftentfeuchter aufweist, um das Klima in dem Siebmagazin 3 zu beeinflussen. Insbesondere wird das Klima dabei derart beeinflusst, dass auf dem jeweiligen Drucksieb 11 verbliebene Reste der Druckmasse fließfähig gehalten werden. Ein Vertrocknen wird somit verhindert. Dies hat den Vorteil, dass die Drucksiebe 11 auch über einen längeren Zeitraum in dem Siebmagazin 3 vorgehalten werden können, ohne dass sie gereinigt werden müssen. Dies führt dazu, dass Druckmasse auch absichtlich auf dem jeweiligen Drucksieb 11 hinterlassen werden kann. Es muss daher bei dem Befüllen des Drucksiebs 11 weniger darauf geachtet werden, dass eine Maximalmenge verwendet wird, um einen Ausschuss oder Verlust der Druckmasse durch eine anschließende Reinigung zu vermeiden. Stattdessen wird die Druckmasse wiederverwendet, sobald das Drucksieb 11 aus dem Siebmagazin 3 wieder entnommen und einem weiteren Druckvorgang zugrunde gelegt wird. Selbstverständlich ist die Konditioniereinrichtung 23 auch bei dem Ausführungsbeispiel von
Grundsätzlich kann die Transporteinrichtung 4 vollständig in die Druckvorrichtung 2 oder auch vollständig in das Siebmagazin 3 integriert sein. Optional wird die Transporteinrichtung teilweise von der Druckvorrichtung und teilweise von dem Siebmagazin 3 gebildet. Dazu weist das Siebmagazin 3 beispielsweise eine Schiebeeinrichtung 24 auf, wie sie in
Gemäß einem weiteren Ausführungsbeispiel kann vorgesehen sein, dass die Schiebeeinrichtung 24 derart ausgebildet ist, dass sie das Drucksieb vollständig durch die Entnahmeöffnung 15 hindurch bis in die Siebaufnahme 10 schiebt. Wenn die Entnahmeöffnung 15 und Siebaufnahme 10 miteinander fluchten, ist dies einfach und kostengünstig realisierbar. Zweckmäßigerweise weist dann die Druckvorrichtung 2 eine entsprechende Schiebeeinrichtung auf, welche dazu ausgebildet ist, das Drucksieb 11 nach einem durchgeführten Druckvorgang zurück in das Siebmagazin und das der Entnahmeöffnung 15 zugeordnete Sieblager zu schieben.According to a further exemplary embodiment, it can be provided that the sliding
Die Module sind dabei zusammen durch ein Gehäuse 30 eingehaust, das optional eine oder mehrere Wartungstüren 34 aufweist, durch welche ein Benutzer sich Zugang zu dem Siebbereitstellungssystem 25 beschaffen kann. Zwischen zwei benachbarten Modulen, in diesem Fall dem Siebmagazin 3_1 und der Behandlungsstation 28, ist eine Siebnutzungsstation 31 angeordnet, die ebenfalls durch die Transporteinrichtung 4 bedient werden kann.The modules are housed together by a
Gemäß dem vorliegenden Ausführungsbeispiel ist die Siebnutzungsstation 31 als die Druckvorrichtung 2 ausgebildet. Alternativ kann die Siebnutzungseinrichtung jedoch auch als Siebentnahmestation 32 ausgebildet sein, an welcher dem Benutzer ein ausgewähltes Sieb aus einem der Siebmagazine 3_1 bis 3_3 oder 3 durch die Transporteinrichtung 4 zur Verfügung gestellt werden kann, sodass der Benutzer dieses ausgewählte Drucksieb 11 manuell zu einer gewünschten Druckvorrichtung oder zu einer anderen Verwendung verbringt. Auch kann an der Siebnutzungsstation 31 ein Fahrroboter oder ein ähnliches Verbindungssystem lokalisiert sein, durch welchen ein zur Verfügung gestelltes Drucksieb einer Druckvorrichtung oder dergleichen automatisiert zugeführt werden kann. So kann beispielsweise das Siebbereitstellungssystem 25 als zentrales Siebbereitstellungssystem in einer Druckhalle mit einer Vielzahl von Druckvorrichtungen genutzt werden. Auch kann das Siebbereitstellungssystem 25 in eine In Line-3D-Drucklinie intergiert werden, wobei dann die Siebnutzungsstation 31 beispielsweise die Druckvorrichtung 2 aufweist, welche dann für einen automatisierten Transport der Trägersubstrate in die Druckvorrichtung 2 und aus der Druckvorrichtung heraus mit darauf befindlichen dreidimensional geformten Strukturen ausgebildet ist.According to the present exemplary embodiment, the
Bei den Behandlungsstationen 26, 27 und 28 handelt es sich insbesondere um unterschiedliche Behandlungsstationen. Gemäß dem vorliegenden Ausführungsbeispiel ist die Behandlungsstation 26 als Siebreinigungsstation ausgebildet. Diese ist dazu ausgebildet, ein von der Transporteinrichtung 4 zur Verfügung gestelltes Drucksieb zu reinigen und dadurch sämtliche Reste von Druckmasse von dem Drucksieb zu entfernen. Nach der erfolgten Reinigung wird das betroffene Drucksieb beispielsweise durch die Transporteinrichtung 4 zurück in eines der Siebmagazine 3 bis 3_3 verbracht.The
Bei der Behandlungsstation 27 handelt es sich vorliegend um eine Siebbefüllungsstation, die dazu ausgebildet ist, ein ihr zugeführtes Drucksieb mit zumindest einem Werkstoff beziehungsweise einem Material einer Druckmasse zu befüllen. Dadurch erfolgt eine zentralisierte Befüllung der Drucksiebe 11 durch die Siebbefüllungsstation 27.
