Definitions
- the invention relates to a device for core packaging with a transport device acting between a removal station of a core shooter and a transfer station, a packaging device having at least a first manipulator and adhesive application means and optionally a coupled immersion bath and a downstream drying oven.
- the device known from DE-A-3 526 265 is problematic in practice, however, since only cores from a single core shooter can be packaged there. In particular in the case of core packages with a large number of cores or with a complex structure, however, it is necessary to produce the individual cores with a wide variety of tools on different core shooting machines and to combine them into a core package. Furthermore, in the known device, the handling of the cores via the adhesive application step up to the pressing step is complex and requires a considerable outlay on equipment.
- the present invention is based on the object of designing and developing the known device for core packaging in such a way that on the one hand a quick automatic assembly of even complex core packages is possible with the least possible design effort and on the other hand the removal of the cores is as gentle as possible, i.e. is possible without the risk of destruction when gripping or placing on a transport device.
- the device according to the invention for core packaging solves the above object by the features of claim 1. Thereafter, the above-mentioned device for core compacting is designed such that at least two core shooters are provided that the transport device has at least one transport pallet for storing the cores and that the transport pallet an air cushion for storage is assigned to each core.
- At least two core shooters are provided here for the implementation of complex core packages with different cores, the cores of which can be fed to a single device for core packaging. Regardless of which core shooter the cores come from, the cores can be fed to a common transfer station. This transfer station forms, so to speak, a node before the actual core packaging, from where the individual cores are fed to the packaging device - piece by piece.
- the transport device has at least one transport pallet for storing the cores, this transport pallet in turn comprising an air cushion for storing each individual core. It does not matter here whether each core shooter has its own removal station or, for example, two core shooters have a common removal station. In any case, it is essential here that the cores are placed in the removal station on a transport pallet assigned to the transport device.
- each core shooter is assigned its own removal station and the cores can be stored in this removal station on a transport range assigned to the transport device.
- This transport range could have special - rigid - receptacles for the core.
- this requires an exact adjustment of the recordings, so that when the core is taken over, no stresses and consequent destruction of the core occur.
- the cores could each be deposited from the upper part of the tool onto the air cushions, the air cushions approximately adapting to the position of the cores "hanging" on the upper part of the tool. In other words, the air cushions could practically float towards the cores "hanging" on the upper part of the tool before removal, which makes special adjustment unnecessary. Damage to the cores is therefore largely excluded. Only when the cores lay on the air cushion would they be pushed off or ejected from the upper part of the tool. Bracing is impossible due to the quasi "floating" air cushions.
- the transport pallets - possibly on a transport carriage - can be moved under the first manipulator or the first manipulator over the transport pallets.
- the cores in particular within the scope of the alternative, which is also claimed as essential to the invention, can be gripped by covering the shortest paths through the first manipulator and stored or stacked for packaging. Specifically, the cores are placed on top of one another on a carriage or undercarriage, the sequence of the cores to be gripped and deposited can be predetermined as desired using a corresponding control.
- the adhesive application means could apply the adhesive to the surfaces of the cores intended for mutual contact before, during or after handling by the first manipulator.
- the first or lowest core could be provided with adhesive on its upper surface, onto which the second core, which is also provided with adhesive on its upper surface, is then pressed or placed.
- the package could be pressed uniaxially so that the adhesive located between the cores is completely pressed into the pores of the cores.
- the pressing process could already take place when the cores were placed on top of one another, so that further handling for pressing was no longer necessary.
- the stacked and glued cores are then pivoted by preferably 90 ° by means of the first manipulator or by means of a subsequent swivel device. Consequently, the cores are stacked out of one another Position placed in a row or next to each other.
- the first manipulator which has already been mentioned several times, could have grippers or clamping jaws acting on both sides for handling the cores, the contact pressures required for gripping or clamping being adjusted to the low strength of the cores.
- the swivel device which could also have grippers or clamping jaws acting on both sides of the cores.
- a second manipulator is used to take over the pivoted core package and to deliver it to a downstream immersion or black bath.
- a coating or impregnation takes place in the surface area of the core package, which prevents liquid iron from burning into the core sand during casting.
- the surface of the core package is refined here.
- the second manipulator could also have grippers or clamping jaws acting on both sides of the cores, for which the above-mentioned applies to the first manipulator.
- the second manipulator could also be used to transfer the core package removed from the immersion bath to a drying oven.
- This drying oven could, in a further advantageous manner and in particular to compensate for the considerable throughput times, two core packages at the same time, i.e. side by side, can be fed. Any type of oven, especially a belt oven or a push-through oven, would come into question here.
- FIGS. 1 and 2 show slightly modified devices for core packaging with a transport device 4 acting between a removal station 1, a core shooting machine 2 and a transfer station 3 and a packaging device 5.
- the packaging device 5 has two manipulators 6 and adhesive application means 8.
- An immersion bath 9 and a drying oven 10 are connected or connected downstream.
- the coring device 5 can be fed cores 11 from two core shooters 2 via the transfer station 3, which can be seen in particular in FIG. 1.
- each core shooter 2 delivers a total of three cores 11.
- each core shooting machine 2 is assigned a removal station 1, the cores 11 in the removal station 1 being able to be placed on a transport pallet 12 assigned to the transport device 4.
- the core shooter 2 supplies a total of four cores 11, the number of cores 11 which can be produced simultaneously for each tool set depending on the geometry or their space requirement.
- the transport pallet 12 has an air cushion 13 for each core 11 for storage.
- the cores 11 can be deposited on the air cushions 13 from the tool upper part 14, which is only indicated in FIG. 2, the air cushions 13 roughly adapting to the position of the cores 11 hanging on the tool upper part 14 during transfer or removal.
- FIG 1 again shows that the transport pallets 12 can be fed to the transfer station 3 on both sides and can be positioned approximately next to one another in the transfer station 3. Due to the movability of the first manipulator 6, it can be moved over or above the transport pallets 12 and is used for gripping and depositing or stacking the cores 11 on a carriage 15. The cores 11 are placed or stacked on top of one another there, the ones shown in FIG 1 only indicated adhesive application means 8 are used for the partial application of adhesive as well as certain surfaces of the cores for mutual contact. The adhesive is applied either before, during or after handling by the first manipulator 6.
- a special swiveling device 17 which is arranged downstream of the first manipulator 6, is provided, which serves for swiveling the stacked or glued cores 11 by preferably 90 °. Both the first manipulator 6 and the swiveling device 17 have clamping jaws 18 acting on both sides of the cores, by means of which the cores 11 and the core package 20 are gripped.
- a second manipulator 19 serves to take over the pivoted core package 20 and to deliver it to the immersion bath 9. There the core package 20 could be placed on a lifting device and - on a corresponding support 16 - lowered into the immersion bath 9.
- the core package 20 is taken over again by the second manipulator 19, which can also have grippers or clamping jaws 18 acting on both sides of the cores 111 and which grips or clamps the core package 20 in the usual way.
- the second manipulator 19 then finally serves to pass on the core package 20 to the drying oven 10, into which two core packages 20 positioned next to one another can be introduced simultaneously.

Description
Die Erfindung betrifft eine Vorrichtung zum Kernpaketieren mit einer zwischen einer Entnahmestation einer Kernschießmaschine und einer Übergabestation wirkenden Transporteinrichtung, einer mindestens einen ersten Manipulator und Klebstoffauftragsmittel aufweisenden Paketiereinrichtung und ggf. einem angekoppelten Tauchbad sowie einem nachgeschalteten Trockenofen.The invention relates to a device for core packaging with a transport device acting between a removal station of a core shooter and a transfer station, a packaging device having at least a first manipulator and adhesive application means and optionally a coupled immersion bath and a downstream drying oven.
Vorrichtungen der in Rede stehenden Art sind seit Jahren aus der Praxis bekannt. Lediglich beispielhaft wird hierzu auf die DE-A-3 526 265 verwiesen. Aus dieser Druckschrift ist eine Kern-Paketiermaschine für den vollautomatischen Zusammenbau gießfertiger Kernpakete bekannt. Mit einer Kernschießmaschine gefertigte Kerne werden dort der Kernschießmaschine entnommen, auf eine Palette verbracht, von dort aus in eine Kern-Schwenkvorrichtung angehoben, dort von einer Spannvorrichtung seitlich umgriffen und gemeinsam - voneinander beabstandet - mittels Klebstoffauftragsmitteln mit Klebstoff versehen. Erst danach werden die Kerne in eine Paketiereinrichtung durch Hubmittel verbracht und nach Rückziehen der Spannvorrichtung verpreßt.Devices of the type in question have been known in practice for years. By way of example only, reference is made to DE-A-3 526 265. A core packaging machine for the fully automatic assembly of cast core packages is known from this publication. Cores manufactured with a core shooter are removed from the core shooter there, placed on a pallet, raised from there into a core swivel device, gripped there laterally by a tensioning device and jointly provided with adhesive by means of adhesive application means. Only then are the cores brought into a packaging device by lifting means and pressed after the tensioning device has been withdrawn.
Die aus der DE-A-3 526 265 bekannte Vorrichtung ist jedoch in der Praxis problematisch, da dort ausschließlich Kerne aus einer einzigen Kernschießmaschine paketierbar sind. Insbesondere bei Kernpaketen mit sehr vielen Kernen oder mit komplexem Aufbau ist es jedoch erforderlich, die einzelnen Kerne mit unterschiedlichsten Werkzeugen auf unterschiedlichen Kernschießmaschinen herzustellen und diese zu einem Kernpaket zusammenzufügen. Des weiteren ist bei der bekannten Vorrichtung die Handhabung der Kerne über den Schritt des Klebstoffauftrags bishin zum Verpressen aufwendig und erfordert einen erheblichen apparativen Aufwand.The device known from DE-A-3 526 265 is problematic in practice, however, since only cores from a single core shooter can be packaged there. In particular in the case of core packages with a large number of cores or with a complex structure, however, it is necessary to produce the individual cores with a wide variety of tools on different core shooting machines and to combine them into a core package. Furthermore, in the known device, the handling of the cores via the adhesive application step up to the pressing step is complex and requires a considerable outlay on equipment.
Aus der DE-A-3 624 554 ist für sich gesehen eine Vorrichtung zum Kernpaktieren bekannt, wobei sowohl die Ablage der Kerne als auch des Kernpaketes auf einer Transporteinrichtung bzw. auf einem Ablagetisch - starr - erfolgt. Folglich ist hier weder vom Einsatz mindestens zweier Kernschießmaschinen und einer Kombination der Kerne aus unterschiedlichen Kernschießmaschinen noch von einer schonenden Kernentnahme bzw. Kernablage die Rede.From DE-A-3 624 554, an apparatus for core compacting is known per se, wherein both the cores and the core package are deposited - rigidly - on a transport device or on a storage table. As a result, there is no use of at least two core shooters and a combination the cores from different core shooters still speak of a gentle core removal or core storage.
Der vorliegenden Erfindung liegt nun die Aufgabe zugrunde, die bekannte Vorrichtung zum Kernpaketieren so auszugestalten und weiterzubilden, daß einerseits ein schnelles automatisches Zusammenfügen auch aufwendiger Kernpakete mit geringstmöglichem konstruktiven Aufwand möglich ist und andererseits die Entnahme der Kerne möglichst schonend, d.h. ohne die Gefahr der Zerstörung beim Greifen oder Aufsetzen auf eine Transporteinrichtung, möglich ist.The present invention is based on the object of designing and developing the known device for core packaging in such a way that on the one hand a quick automatic assembly of even complex core packages is possible with the least possible design effort and on the other hand the removal of the cores is as gentle as possible, i.e. is possible without the risk of destruction when gripping or placing on a transport device.
Die erfindungsgemäße Vorrichtung zum Kernpaketieren löst die voranstehende Aufgabe durch die Merkmale des Patentanspruches 1. Danach ist die einganges genannte Vorrichtung zum Kernpaktieren derart ausgebildet, daß mindestens zwei Kernschießmaschinen vorgesehen sind, daß die Transporteinrichtung mindestens eine zur Ablage der Kerne dienende Transportpalette aufweist und daß der Transportpalette für jeden Kern ein zur Ablage dienendes Luftkissen zugeordnet ist.The device according to the invention for core packaging solves the above object by the features of claim 1. Thereafter, the above-mentioned device for core compacting is designed such that at least two core shooters are provided that the transport device has at least one transport pallet for storing the cores and that the transport pallet an air cushion for storage is assigned to each core.
Erfindungsgemäß sind hier zur Realisierung auch aufwendiger Kernpakete mit unterschiedlichen Kernen mindestens zwei Kernschießmaschinen vorgesehen, deren Kerne einer einzigen Vorrichtung zum Kernpaketieren zuführbar sind. Ungeachtet von welcher Kernschießmaschine die Kerne stammen, lassen sich die Kerne einer gemeinsamen Übergabestation zuführen. Diese Übergabestation bildet sozusagen einen Knotenpunkt vor der eigentlichen Kernpaketierung, von wo aus die einzelnen Kerne der Paketiereinrichtung - Stück für Stück - zugeführt werden.According to the invention, at least two core shooters are provided here for the implementation of complex core packages with different cores, the cores of which can be fed to a single device for core packaging. Regardless of which core shooter the cores come from, the cores can be fed to a common transfer station. This transfer station forms, so to speak, a node before the actual core packaging, from where the individual cores are fed to the packaging device - piece by piece.
In weiter erfindungsgemäßer Weise weist die Transporteinrichtung mindestens eine zur Ablage der Kerne dienende Transportpalette auf, wobei diese Transportpalette wiederum für jeden einzelnen Kern ein zur Ablage dienendes Luftkissen umfaßt. Nun spielt es hier keine Rolle, ob jeder Kernschießmaschine eine eigene Entnahmestation oder bspw. zwei Kernschießmaschinen eine gemeinsame Entnahmestation zugeordnet ist. Jedenfalls ist hier wesentlich, daß die Kerne in der Entnahmestation auf eine der Transporteinrichtung zugeordnete Transportpalette abgelegt werden.In a further inventive manner, the transport device has at least one transport pallet for storing the cores, this transport pallet in turn comprising an air cushion for storing each individual core. It does not matter here whether each core shooter has its own removal station or, for example, two core shooters have a common removal station. In any case, it is essential here that the cores are placed in the removal station on a transport pallet assigned to the transport device.
Im Gegensatz zu den aus dem Stand der Technik bekannten starren Aufnahmen mit anschließender aufwendiger mechanischer Justierung ist hier dafür Sorge getragen, daß bei einer Übernahme des Kerns keine mechanischen Spannungen am Kern auftreten und somit die Gefahr einer Beschädigung des Kerns wirksam vermieden ist. Dies erfolgt durch die zur Ablage dienenden Luftkissen, wobei sich diese Luftkissen der Position der vor der Entnahme in der Regel am Werkzeugoberteil "hängenden" Kerne in etwa anpassen können. Mit anderen Worten können die Luftkissen den vor der Entnahme noch am Werkzeugoberteil "hängenden" Kerne quasi entgegenschwimmen, wodurch sich eine automatische Justierung ergibt. Eine besondere - separate - Justierung erübrigt sich demnach. Eine Beschädigung der Kerne ist durch Vorkehrung der Luftkissen weitgehend ausgeschlossen. Erst wenn die Kerne auf dem Luftkissen aufliegen, werden sie vom Werkzeugoberteil ab- bzw. ausgestoßen, so daß ein Verspannen durch eine starre Aufnahme aufgrund der quasi "schwimmenden" Luftkissen wirksam vermieden ist.In contrast to the rigid receptacles known from the prior art with subsequent complex mechanical adjustment, care is taken here that no mechanical stresses occur on the core when the core is taken over and the risk of damage to the core is thus effectively avoided. This is done by means of the air cushions used for storage, these air cushions being able to adapt approximately to the position of the cores which are generally "hanging" on the upper part of the tool before removal. In other words, the air cushions can virtually float against the cores which are still "hanging" on the upper part of the tool before removal, which results in an automatic adjustment. A special - separate - adjustment is therefore unnecessary. Damage to the cores is largely excluded by taking precautions against the air cushions. Only when the cores rest on the air cushion are they pushed or ejected from the upper part of the tool, so that tensioning due to a rigid receptacle due to the quasi "floating" air cushion is effectively avoided.
Hinsichtlich eines besonders einfachen und dabei sicheren Verbringens der Kerne von der Entnahmestation der Kernschießmaschine zu der als Knotenpunkt dienenden Übergabestation ist es von besonderem Vorteil, wenn jeder Kernschießmaschine eine eigene Entnahmestation zugeordnet ist und die Kerne in dieser Entnahmestation auf eine der Transporteinrichtung zugeordneten Transportpalette ablegbar sind. Diese Transportpalette könnte besondere - starre - Aufnahmen für den Kern aufweisen. Dies erfordert jedoch eine exakte Justierung der Aufnahmen, so daß bei einer Übernahme des Kerns keine Spannungen und dadurch hervorgerufene Zerstörungen des Kerns auftreten.With regard to a particularly simple and safe transfer of the cores from the removal station of the core shooter to the transfer station serving as a node, it is particularly advantageous if each core shooter is assigned its own removal station and the cores can be stored in this removal station on a transport range assigned to the transport device. This transport range could have special - rigid - receptacles for the core. However, this requires an exact adjustment of the recordings, so that when the core is taken over, no stresses and consequent destruction of the core occur.
Die Kerne könnten jeweils vom Werkzeugoberteil auf die Luftkissen ablegbar sein, wobei sich die Luftkissen der Position der am Werkzeugoberteil "hängenden" Kerne in etwa anpassen. Mit anderen Worten könnten die Luftkissen den vor der Entnahme noch am Werkzeugoberteil "hängenden" Kernen quasi entgegenschwimmen, wodurch sich eine besondere Justierung erübrigt. Eine Beschädigung der Kerne ist somit weitgehend ausgeschlossen. Erst wenn die Kerne auf dem Luftkissen aufliegen, würden sie vom Werkzeugoberteil ab- bzw. ausgestoßen werden. Ein Verspannen ist aufgrund der quasi "schwimmenden" Luftkissen ausgeschlossen.The cores could each be deposited from the upper part of the tool onto the air cushions, the air cushions approximately adapting to the position of the cores "hanging" on the upper part of the tool. In other words, the air cushions could practically float towards the cores "hanging" on the upper part of the tool before removal, which makes special adjustment unnecessary. Damage to the cores is therefore largely excluded. Only when the cores lay on the air cushion would they be pushed off or ejected from the upper part of the tool. Bracing is impossible due to the quasi "floating" air cushions.
In weiter vorteilhafter Weise und insbesondere zur Verifizierung der zu paketierenden Kernpakete ist es von besonderem Vorteil, wenn zwei Kernschießmaschinen mit je einer Entnahmestation vorgesehen sind. Die in der Entnahmestation mit Kernen beladenen Transportpaletten könnten dann bspw. beidseitig der Übergabestation dieser zugeführt und in der Übergabestation in etwa nebeneinander positioniert werden. Die Paketiereinrichtung könnte sich dann aus beiden Transportpaletten bedienen.In a further advantageous manner and in particular for verifying the core packages to be packaged, it is particularly advantageous if two core shooting machines are provided, each with a removal station. The transport pallets loaded with cores in the removal station could then, for example, be fed to the transfer station on both sides thereof and be positioned approximately next to one another in the transfer station. The packaging device could then use both transport pallets.
Hinsichtlich einer sicheren Übernahme der Kerne in der Übergabestation ist es von weiterem Vorteil, wenn die Transportpaletten - ggf. auf einem Transportschlitten - unter dem ersten Manipulator bzw. der erste Manipulator über die Transportpaletten verfahrbar ist. Von dort aus lassen sich die Kerne, insbesondere im Rahmen der ebenfalls als erfindungswesentlich beanspruchten Alternative, unter Zurücklegung kürzester Wege durch den ersten Manipulator greifen und zur Paketierung ablegen bzw. stapeln. Im konkreten werden die Kerne dazu auf einem Schlitten oder Fahrwerk - aufeinander - abgelegt, wobei die Reihenfolge der zu ergreifenden und abzulegenden Kerne über eine entsprechende Steuerung beliebig vorgebbar ist.With regard to a safe transfer of the cores in the transfer station, it is of further advantage if the transport pallets - possibly on a transport carriage - can be moved under the first manipulator or the first manipulator over the transport pallets. From there, the cores, in particular within the scope of the alternative, which is also claimed as essential to the invention, can be gripped by covering the shortest paths through the first manipulator and stored or stacked for packaging. Specifically, the cores are placed on top of one another on a carriage or undercarriage, the sequence of the cores to be gripped and deposited can be predetermined as desired using a corresponding control.
Hinsichtlich einer wirksamen Verbindung der zu paketierenden Kerne ist es von ganz besonderem Vorteil, wenn die Kerne mittels eines Klebstoffs zumindest partiell miteinander verklebt werden. Dazu könnten die Klebstoffauftragsmittel den Klebstoff vor, während oder nach der Handhabung durch den ersten Manipulator auf die zur gegenseitigen Anlage bestimmten Flächen der Kerne aufbringen. Im konkreten könnte der erste bzw. unterste Kern auf seiner oberen Fläche mit Klebstoff versehen werden, auf die dann der zweite Kern, der auf seiner oberen Fläche ebenfalls mit Klebstoff versehen ist, aufgedrückt bzw. aufgelegt wird. Nach Stapelung der einzelnen Kerne gemäß der voranstehenden Beschreibung könnte das Paket nochmals einaxial verpreßt werden, damit nämlich der zwischen den Kernen befindliche Klebstoff vollends in die Poren der Kerne gedrückt wird. Der Vorgang des Verpressens könnte jedoch bereits beim Auflegen der Kerne aufeinander erfolgen, so daß eine weitere Handhabung zum Verpressen nicht mehr erforderlich ist.With regard to an effective connection of the cores to be packaged, it is particularly advantageous if the cores are at least partially glued to one another by means of an adhesive. For this purpose, the adhesive application means could apply the adhesive to the surfaces of the cores intended for mutual contact before, during or after handling by the first manipulator. Specifically, the first or lowest core could be provided with adhesive on its upper surface, onto which the second core, which is also provided with adhesive on its upper surface, is then pressed or placed. After stacking the individual cores as described above, the package could be pressed uniaxially so that the adhesive located between the cores is completely pressed into the pores of the cores. However, the pressing process could already take place when the cores were placed on top of one another, so that further handling for pressing was no longer necessary.
In einem nächsten Schritt werden nun die gestapelten und verklebten Kerne mittels des ersten Manipulators oder mittels einer nachgeschalteten Schwenkeinrichtung um vorzugsweise 90° geschwenkt. Folglich werden die Kerne aus der aufeinandergestapelten Position in eine hintereinander oder nebeneinander liegende Position verbracht. Der zuvor bereits mehrfach erwähnte erste Manipulator könnte zur Handhabung der Kerne beidseits wirkende Greifer oder Spannbacken aufweisen, wobei zum Greifen bzw. Spannen erforderliche Anpreßdrücke auf die geringe Festigkeit der Kerne einzustellen sind. Gleiches gilt für die Schwenkeinrichtung, die ebenfalls beidseits der Kerne wirkende Greifer oder Spannbacken aufweisen könnte.In a next step, the stacked and glued cores are then pivoted by preferably 90 ° by means of the first manipulator or by means of a subsequent swivel device. Consequently, the cores are stacked out of one another Position placed in a row or next to each other. The first manipulator, which has already been mentioned several times, could have grippers or clamping jaws acting on both sides for handling the cores, the contact pressures required for gripping or clamping being adjusted to the low strength of the cores. The same applies to the swivel device, which could also have grippers or clamping jaws acting on both sides of the cores.
Nachdem nun die Kerne bzw. das gemäß voranstehender Beschreibung hergestellte Kernpaket um 90° geschwenkt auf einem Schlitten oder Fahrwerk abgelegt ist, dient ein zweiter Manipulator zur Übernahme des geschwenkten Kernpakets und zur Abgabe an ein nachgeschaltetes Tauch- bzw. Schwärzebad. Hier erfolgt eine Beschichtung bzw. ein Tränken im Oberflächenbereich des Kernpakets, wodurch verhindert wird, daß sich beim Gießen flüssiges Eisen in den Kernsand hineinbrennt. Mit anderen Worten wird hier die Oberfläche des Kernpakets veredelt. Auch der zweite Manipulator könnte beidseits der Kerne wirkende Greifer oder Spannbacken aufweisen, für die das zuvor gesagte betreffend den ersten Manipulator gilt.After the cores or the core package produced according to the above description has been placed on a sled or undercarriage pivoted through 90 °, a second manipulator is used to take over the pivoted core package and to deliver it to a downstream immersion or black bath. Here, a coating or impregnation takes place in the surface area of the core package, which prevents liquid iron from burning into the core sand during casting. In other words, the surface of the core package is refined here. The second manipulator could also have grippers or clamping jaws acting on both sides of the cores, for which the above-mentioned applies to the first manipulator.
Schließlich könnte der zweite Manipulator auch zur Weitergabe des aus dem Tauchbad wieder entnommenen Kernpakets an einen Trockenofen dienen. Diesem Trockenofen könnten in weiter vorteilhafter Weise und insbesondere zur Kompensation der doch erheblichen Durchlaufzeiten gleichzeitig zwei Kernpakete parallel, d.h. nebeneinander, zuführbar sein. Hier kämen jedwede Öfen, insbesondere Bandöfen oder Durchstoßöfen, in Frage.Finally, the second manipulator could also be used to transfer the core package removed from the immersion bath to a drying oven. This drying oven could, in a further advantageous manner and in particular to compensate for the considerable throughput times, two core packages at the same time, i.e. side by side, can be fed. Any type of oven, especially a belt oven or a push-through oven, would come into question here.
Es gibt nun verschiedene Möglichkeiten, die Lehre der vorliegenden Erfindung in vorteilhafter Weise auszugestalten und weiterzubilden. Dazu ist einerseits auf die den Patentansprüchen 1 und 2 nachgeordneten Ansprüche, andererseits auf die nachfolgende Erläuterung zweier Ausführungsbeispiele der Erfindung anhand der Zeichnung zu verweisen.

Gemäß der Darstellung in Fig. 1 weist die Paketiereinrichtung 5 zwei Manipulatoren 6, und Klebstoffauftragsmittel 8 auf. Ein Tauchbad 9 sowie ein Trockenofen 10 sind nachgeschaltet bzw. angekoppelt.According to the illustration in FIG. 1, the
Erfindungsgemäß sind der Paketiereinrichtung 5 über die Übergabestation 3 Kerne 11 von zwei Kernschießmaschinen 2 zuführbar, was sich insbesondere der Fig. 1 entnehmen läßt. Bei dem in Fig. 1 gewählten Ausführungsbeispiel liefert jede Kernschießmaschine 2 insgesamt drei Kerne 11.According to the invention, the
Jeder Kernschießmaschine 2 ist gemäß der Darstellung in Fig. 2 eine Entnahmestation 1 zugeordnet, wobei die Kerne 11 in der Entnahmestation 1 auf einer der Transporteinrichtung 4 zugeordneten Transportpalette 12 ablegbar sind. Bei dem in Fig. 2 gewählten Ausführungsbeispiel liefert die Kernschießmaschine 2 insgesamt vier Kerne 11, wobei die Anzahl der je Werkzeugsatz gleichzeitig herstellbaren Kerne 11 von der Geometrie bzw. deren Raumbedarf abhängt.As shown in FIG. 2, each

Die Kerne 11 sind von dem in Fig. 2 lediglich angedeuteten Werkzeugoberteil 14 auf die Luftkissen 13 ablegbar, wobei sich die Luftkissen 13 der Position der am Werkzeugoberteil 14 hängenden Kerne 11 - bei der Übergabe bzw.

Aufgrund der Verfahrbarkeit des ersten Manipulators 6 ist dieser über die bzw. oberhalb der Transportpaletten 12 verfahrbar und dient zum Ergreifen und Ablegen bzw. Stapeln der Kerne 11 auf einem Schlitten 15. Die Kerne 11 werden dort aufeinander abgelegt bzw. gestapelt, wobei die in Fig. 1 lediglich angedeuteten Klebstoffauftragsmittel 8 zum partiellen Auftragen von Klebstoff sowie zur gegenseitigen Anlage bestimmten Flächen der Kerne dienen.
