Description

Die Erfindung betrifft eine Vorrichtung und ein Verfahren zum Reinigen von becherartigen Behältnissen von Spritzpistolen sowie eine diesbezügliche Verwendung.The invention relates to a device and a method for cleaning cup-like containers of spray guns and a related use.

Aus dem Stand der Technik sind Vorrichtungen zum Reinigen von becherartigen Behältnissen von Spritzpistolen, Spritzpistolen und deren Teilen bekannt, bei denen mittels gestellähnlicher Aufnahmeeinrichtungen die zu reinigenden Teile, Spritzpistolen und Behältnisse von Spritzpistolen, im nachfolgenden auch als "zu reinigende Gegenstände" bezeichnet, aufgenommen werden, wobei im Anschluss daran die drahtgestellartigen Aufnahmeeinrichtungen - ähnlich wie bei einem Geschirrspüler - eingesetzt werden in die vorhandenen Reinigungsvorrichtungen, um dann anschließend diese mittels mindestens eines Reinigungsmittels zu reinigen. Dabei können in mehreren Reinigungsschritten aufgrund der hintereinander folgenden Reinigungsschritte durch Vorreinigen der vorhergehenden Reinigungen die unterschiedlich mit den zu entfernenden Stoffen belasteten Reinigungsflüssigkeiten über unterschiedliche Abläufe in einem einzigen Reinigungskompartiment solcher Reinigungsvorrichtungen unterschiedlichen Auffangbehältnissen zugeführt werden. Da selbst bei gezieltem Einsatz von entsprechenden inneren eingebauten Düsen es nicht vollständig zu vermeiden ist, dass zumindest ein kleiner Teil der unterschiedliche stark belasteten Reinigungsmittel bei den jeweiligen Reinigungsschritten auch unbeabsichtigt in den eigentlich dafür vorgesehenen Ablauf läuft und es somit nicht zu einem wirklich sehr sauberen Auffang der unterschiedlich stark belasteten Reinigungsfraktion der entsprechenden Auffangbehälter realisierbar ist, ist es in nicht wenigen Fällen nicht mehr möglich, ein weniger stark mit zu entfernenden Stoffen kontaminiertes Reinigungsmittel, das normalerweise aufgrund der Tatsache, dass es sich um einen Reinigungsschritt handelt, der nach einer ersten Vorreinigung stattfindet, nicht ohne weiteres wiederverwendet werden kann, sodass ein zum Teil nicht unbeträchtlicher Reinigungsmittelverbrauch festzustellen ist.Devices for cleaning cup-like containers of spray guns, spray guns and their parts are known from the prior art, in which the parts to be cleaned, spray guns and containers of spray guns, hereinafter also referred to as "objects to be cleaned", are picked up by means of frame-like receiving devices , whereby the wire frame-like receiving devices - similar to a dishwasher - are then inserted into the existing cleaning devices in order to then clean them using at least one cleaning agent. In several cleaning steps, due to the successive cleaning steps by pre-cleaning the previous cleaning, the cleaning liquids that are differently contaminated with the substances to be removed can be fed to different collecting containers via different processes in a single cleaning compartment of such cleaning devices. Since even with the targeted use of appropriate internal built-in nozzles, it cannot be completely avoided that at least a small part of the different heavily contaminated cleaning agents unintentionally runs into the intended drain during the respective cleaning steps and therefore does not result in a really very clean collection Since the cleaning fraction of the corresponding collecting containers with different levels of contamination can be achieved, in quite a few cases it is no longer possible to use a cleaning agent that is less heavily contaminated with substances to be removed, which is usually due to the fact that it is a cleaning step that occurs after an initial pre-cleaning takes place, cannot be easily reused, so that a not inconsiderable consumption of cleaning agents can be observed.

So wird in DE 902 115 ein Kessel mit mehreren durch eine gemeinsame Feuerung geheizten Kammern beschrieben. Dabei enthält jede Kammer eine zur Speisung der zu dem Kessel gehörigen Vorrichtung bestimmte Flüssigkeit, die unmittelbar erwärmt wird.This is how it is done DE 902 115 a boiler with several chambers heated by a common furnace is described. Each chamber contains a liquid intended to feed the device belonging to the boiler, which is heated immediately.

Aus US 3 888 693 A sind eine Vorrichtung und ein Verfahren zum Reinigen von Gegenständen von verunreinigender Flüssigkeit bekannt. Die Gegenstände werden mit einer Zweiphasenflüssigkeit gewaschen, wobei die beiden Phasen nicht mischbar und nicht löslich sind mit der verunreinigenden Flüssigkeit.Out of US 3,888,693 A a device and a method for cleaning objects from contaminating liquid are known. The articles are washed with a two-phase liquid, the two phases being immiscible and insoluble with the contaminating liquid.

Aus US 2011/068070 A1 sind ein Behälter und ein Verfahren zum Reinigen und Untersuchen von Gegenständen bekannt. Der Behälter ist ein Drahtbehälter mit federartigen Drähten, die so geformt sind, dass sie die Gegenstände stützen, wenn der Behälter geschüttelt wird, so dass sich die Drähte und Gegenstände bewegen.Out of US 2011/068070 A1 a container and a method for cleaning and examining objects are known. The container is a wire container with spring-like wires shaped to support the objects when the container is shaken so that the wires and objects move.

DE 10 2011 015 614 B4 offenbart eine Vorrichtung zum Reinigen von becherartigen Behältnissen von Spritzpistolen, Spritzpistolen und deren Teilen gemäß dem Oberbegriff des Anspruchs 1. Dieses Dokument offenbart insbesondere eine Vorrichtung zum Reinigen von becherartigen Behältnissen von Spritzpistolen, Spritzpistolen und deren Teilen, wobei diese derart ausgestaltet ist, dass beim Durchlaufen einer Reinigung mittels einer Ablaufzuteilungseinrichtung mit zu entfernenden Stoffen unterschiedlich verunreinigte Reinigungsflüssigkeit als Ablauf zumindest teilweise unterschiedlichen Auffangbehältnissen zugeteilt wird, wobei die Ablaufzuteilungseinrichtung Teil einer ersten Pneumatikeinrichtung ist, wobei die Vorrichtung lediglich eine Ablaufzuteilungseinrichtung aufweist und die Vorrichtung eine Dreheinrichtung zum Drehen einer Aufnahmeeinrichtung zur Aufnahme der zu reinigenden becherartigen Behältnisse von Spritzpistolen, Spritzpistolen und deren Teilen aufweist, wobei der pneumatische Betrieb der Dreheinrichtung verhindert, dass sich bei den unterschiedlichen Reinigungsschritten im o.g. Sinne ein stärkeres Vermischen der unterschiedlich kontaminierten bzw. eingesetzten Reinigungsmittel in die jeweiligen Reinigungsschritte ein stärkeres Vermischen dieser beiden Medien nicht verhindert werden kann, da relativ viel Restreiniger in Schläuchen und Ablaufwanne solcher Vorrichtungen sich befindet, welcher in den jeweils anderen Kreislauf nachläuft, sodass eine unnötige Kontamination resp. ein relativ doch hoher Lösungsmittelverbrauch festzustellen ist. DE 10 2011 015 614 B4 discloses a device for cleaning cup-like containers of spray guns, spray guns and their parts according to the preamble of claim 1. This document in particular discloses a device for cleaning cup-like containers of spray guns, spray guns and their parts, which is designed in such a way that when passing through a cleaning by means of a drain allocation device with substances to be removed, differently contaminated cleaning liquid is at least partially allocated as a drain to different collecting containers, the drain allocation device being part of a first pneumatic device, the device having only one drain allocation device and the device having a rotating device for rotating a receiving device for receiving the cleaning cup-like containers of spray guns, spray guns and their parts, whereby the pneumatic operation of the rotating device prevents the different cleaning steps in the above-mentioned sense from causing greater mixing of the differently contaminated or used cleaning agents in the respective cleaning steps and no greater mixing of these two media can be prevented because there is a relatively large amount of residual cleaner in the hoses and drain pan of such devices, which runs into the other circuit, so that unnecessary contamination or a relatively high solvent consumption can be observed.

Das der Erfindung zugrundeliegende Problem besteht daher darin, diesen Nachteil zumindest teilweise zu verringern bis hin zu vermeiden, insbesondere dahin, eine entsprechende Reinigungsvorrichtung bereitzustellen, die sauber voneinander und somit definiert unterschiedlich mit zu entfernenden Stoffen belastete Reinigungsmittel bereitstellt - bei möglichst geringem absoluten Reinigungsmittelverbrauch -, sodass es ermöglicht wird, bei möglichst geringem Gesamtverbrauch an Reinigungsmitteln zumindest einen Teil der nach einem ersten groben Reinigungsschritt (Vorreinigung) nachfolgenden Reinigungsmittelfraktionen zumindest teilweise unmittelbar weiterverwendet werden zu können für weitere Reinigungsschritte bzw. später zu reinigende Gegenstände oder aber zumindest der erste Vorreinigungsschritt derart effizient ausgestaltet ist, dass für die nachfolgende Nachreinigung (Hauptreinigung) im Vergleich zu dem aus der Stand der Technik üblichen Reinigungsverfahren weniger Lösungsmittel hierzugegeben werden muss, um ausgezeichnete Reinigungsergebnisse zu erzielen.The problem on which the invention is based is therefore to at least partially reduce or even avoid this disadvantage, in particular to provide a corresponding cleaning device which provides cleaning agents that are cleanly contaminated with substances to be removed, cleanly from one another and thus in a defined manner - with the lowest possible absolute cleaning agent consumption -, so that with the lowest possible overall consumption of cleaning agents, at least some of the cleaning agent fractions following a first rough cleaning step (pre-cleaning) can be used immediately for further cleaning steps or objects to be cleaned later, or at least the first pre-cleaning step is designed in such an efficient manner is that for the subsequent cleaning (main cleaning) less solvent has to be added compared to the cleaning process usual from the prior art in order to achieve excellent cleaning results.

Dieses Problem bzw. diese Aufgabe wird erfindungsgemäß gelöst durch eine Vorrichtung nach Anspruch 1 und ein Verfahren nach Anspruch 12.This problem or this task is solved according to the invention by a device according to claim 1 and a method according to claim 12.

Bei der erfindungsgemäßen Vorrichtung zum Reinigen von becherartigen Behältnissen von Spritzpistolen, Spritzpistolen und deren Teilen ist die erfindungsgemäße Vorrichtung derart ausgestaltet, dass beim Durchlaufen einer Reinigung mit zu entfernenden Stoffen verunreinigte Reinigungsflüssigkeit als Ablauf einem Auffangbehältnis zugeteilt wird, wobei die Reinigung derart in mindestens zwei, voneinander separierter Reinigungsschritte aufgeteilt wird, dass bei jedem einzelnen Reinigungsschritt eine mit zu entfernenden Stoffen verunreinigte und/oder nicht verunreinigte Reinigungsflüssigkeit als Ablauf einem dem einzelnen Reinigungsschritt ausschließlich zugeteilten Auffangbehältnis zugeteilt wird, wobei die Vorrichtung derart ausgebildet ist, dass die Abläufe im funktionalen Sinne räumlich voneinander getrennt durchgeführt werden, beispielsweise und insbesondere dadurch, dass die zu reinigenden Gegenstände in jeweils einem für jeden Reinigungsschritt ausschließlich zugedachten Reinigungskompartiment mit entsprechendem Ablauf gereinigt werden.In the device according to the invention for cleaning cup-like containers of spray guns, spray guns and their parts, the device according to the invention is designed in such a way that when cleaning is carried out, cleaning liquid contaminated with substances to be removed is allocated to a collecting container as an outlet, the cleaning being carried out in at least two ways from one another is divided into separate cleaning steps so that for each individual cleaning step a cleaning liquid contaminated and/or not contaminated with substances to be removed is allocated as a process to a collecting container exclusively assigned to the individual cleaning step, the device being designed in such a way that the processes are spatially separated from one another in a functional sense can be carried out, for example and in particular by cleaning the objects to be cleaned in a cleaning compartment with a corresponding process that is exclusively intended for each cleaning step.

In diesem Kontext ist es vorteilhaft, da in der Praxis bewährt, wenn die Reinigungsflüssigkeitszuteilung im funktionalen Sinne (ebenfalls) räumlich voneinander getrennt durchgeführt wird.In this context, it is advantageous, as proven in practice, if the cleaning liquid allocation is (also) carried out spatially separated from one another in the functional sense.

Weiterhin ist es von Vorteil, wenn für jeden Reinigungsschritt eine ausschließlich für den jeweiligen Reinigungsschritt zugeordnete Pumpe vorgesehen ist, um in einem solchen Fall eine auch minimale Kontamination der einzelnen Reinigungsmittel aus den entsprechenden Reinigungsschritten bzw. für die entsprechenden Reinigungsschritte vollständig zu vermeiden.Furthermore, it is advantageous if a pump assigned exclusively to the respective cleaning step is provided for each cleaning step in order to completely avoid even minimal contamination of the individual cleaning agents from the corresponding cleaning steps or for the corresponding cleaning steps in such a case.

In diesem Kontext ist es weiterhin von Vorteil, da bewährt, dass für jeden Reinigungsschritt ein ausschließlich für den jeweiligen Reinigungsschritt zugeordnetes Auffangbehältnis vorgesehen ist.In this context, it is also advantageous, as it has been proven, that a collecting container is provided for each cleaning step and is assigned exclusively to the respective cleaning step.

Weiterhin ist es von Vorteil, dass für jeden Reinigungsschritt mindestens ein ausschließlich für den jeweiligen Reinigungsschritt zugeordnetes Reinigungsflüssigkeitsvorratsbehältnis vorgesehen ist.Furthermore, it is advantageous that for each cleaning step at least one cleaning liquid storage container is provided that is exclusively assigned to the respective cleaning step.

Erfindungsgemäß weist die Vorrichtung mindestens einen Halter auf, der im funktionalen Sinne für jeden Reinigungsschritt mindestens zwei zu reinigende Gegenstände hält, wobei es sich in der Praxis vorteilhafterweise bewährt hat, wenn der Halter derart ausgebildet ist, dass die zu reinigenden Gegenstände räumlich ausrichtbar sind, d.h. im Rahmen der zu reinigenden Gegenstände in Bezug auf die in der Regel vorhandenen Düsen in einem jeweiligen Reinigungskompartiment innerhalb der erfindungsgemäßen Vorrichtung.According to the invention, the device has at least one holder which, in a functional sense, holds at least two objects to be cleaned for each cleaning step. In practice, it has proven advantageous if the holder is designed in such a way that the objects to be cleaned can be spatially aligned, i.e. within the scope of the objects to be cleaned in relation to the nozzles generally present in a respective cleaning compartment within the device according to the invention.

In diesem Kontext ist es weiterhin vorteilhaft, da bewährt, dass der Halter mindestens eine Klammer zum Halten und/oder mindestens eine Spreizarmaufnahme zum Halten aufweist, wobei beispielsweise und insbesondere die Klammer für die Befestigung eines Becherdeckels und die Spreizarmaufnahme für die Aufnahme eines Bechers verwendet wird.In this context, it is furthermore advantageous, as proven, for the holder to have at least one clamp for holding and/or at least one spreader arm receptacle for holding, with, for example and in particular, the clamp being used for fastening a cup lid and the spreading arm receptacle for holding a cup .

Weiterhin ist es von Vorteil, da in der Praxis bewährt, wenn der Halter transportabel ausgestaltet ist, beispielsweise und insbesondere dadurch, dass der Halter einen Griff aufweist.Furthermore, it is advantageous, as proven in practice, if the holder is designed to be transportable, for example and in particular in that the holder has a handle.

Es ist weiterhin erfindungsgemäß, wenn für jeden Reinigungsschritt ein ausschließlich für diesen Reinigungsschritt vorgesehenes Reinigungskompartiment realisiert ist.It is furthermore according to the invention if a cleaning compartment intended exclusively for this cleaning step is implemented for each cleaning step.

Weiterhin ist es erfindungsgemäß, wenn in diesem Kontext der Halter bei einem Reinigungsschritt in dem für diesen Reinigungsschritt vorgesehenen Reinigungskompartiment angeordnet ist, wobei es in der Praxis sich als besonders vorteilhaft herausgestellt hat, da sehr verfahrenseffizient, dass der Halter bei jedem Reinigungsschritt in dem für den jeweiligen Reinigungsschritt vorgesehenen Reinigungskompartiment angeordnet ist.Furthermore, it is according to the invention if, in this context, the holder is arranged in the cleaning compartment provided for this cleaning step during a cleaning step, whereby it has proven to be particularly advantageous in practice, since it is very procedurally efficient for the holder to be in the area intended for each cleaning step respective cleaning step provided cleaning compartment is arranged.

Beim erfindungsgemäßen Verfahren zum Reinigen von becherartigen Behältnissen von Spritzpistolen, Spritzpistolen und deren Teilen wird eine erfindungsgemäße Vorrichtung verwendet.In the method according to the invention for cleaning cup-like containers of spray guns, spray guns and their parts, a device according to the invention is used.

Erfindungsgemäß wird der Halter nach einem ersten Reinigungsschritt von diesem ersten Reinigungsschritt zugeordneten Reinigungskompartiment einem für einen weiteren Reinigungsschritt zugeordneten Reinigungskompartiment zugeführt, wobei dies beispielsweise und insbesondere automatisch, halbautomatisch, programmiert automatisch oder manuell durchgeführt werden kann.According to the invention, after a first cleaning step, the holder is fed from the cleaning compartment assigned to this first cleaning step to a cleaning compartment assigned to a further cleaning step, which can be carried out, for example and in particular, automatically, semi-automatically, programmed automatically or manually.

Die Erfindung wird anhand eines nachfolgenden Ausführungsbeispiels nicht beschränkend näher erläutert, wobei

  • Figur 1- eine schematische, perspektivische Darstellung einer möglichen Ausführungsform der erfindungsgemäßen Reinigungsvorrichtung darstellt,
    und
  • Figur 2 - eine schematische, perspektivische Darstellung eines erfindungsgemäßen Halters darstellt, der in eine erfindungsgemäße Reinigungsvorrichtung eingesetzt wird.
The invention is explained in more detail in a non-restrictive manner using the following exemplary embodiment, where:
  • Figure 1 - represents a schematic, perspective view of a possible embodiment of the cleaning device according to the invention,
    and
  • Figure 2 - represents a schematic, perspective view of a holder according to the invention, which is inserted into a cleaning device according to the invention.

In Figur 1 ist skizzenhaft und perspektivisch eine mögliche Ausführungsform der erfindungsgemäßen Vorrichtung zum Reinigen von becherartigen Behältnissen von Spritzpistolen, Spritzpistolen und deren Teilen gezeigt.In Figure 1 A possible embodiment of the device according to the invention for cleaning cup-like containers of spray guns, spray guns and their parts is shown in sketch and perspective form.

Die Reinigungsvorrichtung ist kastenförmig aufgebaut, wobei diese mittels zweier Deckel 8, 8' geschlossen werden kann vor einer Reinigung. Dabei werden aufgewirbelte Reinigungsmitteldämpfe optional abgesaugt über eine entsprechende (nicht gezeigte) Absaugung, wobei mittels einer optionalen Programmiereinheit und/oder einer Zeitschaltuhr für den Benutzer die einzelnen Reinigungsschritte oder jeweils nur ein einzelner Reinigungsschritt von der Zeitdauer eingestellt werden kann.The cleaning device is box-shaped and can be closed by means of two covers 8, 8 'before cleaning. In this case, swirled-up cleaning agent vapors are optionally sucked off via a corresponding suction system (not shown), whereby the individual cleaning steps or only a single cleaning step can be set in terms of duration using an optional programming unit and/or a timer for the user.

Nach Beladen der zu reinigenden Gegenstände, nämlich den becherartigen Behältnissen 1 und den entsprechend dazugehörigen Deckeln 3, in einen Halter 2 in einem Reinigungskompartiment 7 durch Festklemmen mindestens eines zu reinigenden Deckels 3 über mindestens eine Klammer 4 und federnder Spannung mittels eines Spreizarms 5 fixiert, um dann ein Reinigungsprogramm oder einfach lediglich einen Reinigungsschritt bzw. eine Reinigung als solche zu beginnen. Über eine (nicht gezeigte) Pumpe, die ausschließlich für die Vorreinigung vorgesehen ist, die ausschließlich im Reinigungskompartiment 7 stattfindet, wird entsprechend frisches Reinigungsmittel oder nur leicht kontaminiertes Reinigungsmittel zur Vorreinigung der zu reinigenden Gegenstände verwendet.After loading the objects to be cleaned, namely the cup-like containers 1 and the corresponding lids 3, into a holder 2 in a cleaning compartment 7 by clamping at least one lid 3 to be cleaned using at least one clamp 4 and resilient tension by means of a spreading arm 5, in order to then start a cleaning program or simply just a cleaning step or cleaning as such. Using a pump (not shown) which is intended exclusively for the pre-cleaning, which takes place exclusively in the cleaning compartment 7, fresh cleaning agent or only slightly contaminated cleaning agent is used for the pre-cleaning of the objects to be cleaned.

Im Anschluss daran wird nach Öffnen des Deckels 8 der Halter 2 mitsamt den vorgereinigten Gegenständen 1, 3 aus dem mittels eines Griffes 6 (s. Figur 2) überführt in ein zweites Nachreinigungskompartiment 7', wobei bei Beginn des Nachreinigungsschrittes entsprechender Deckel 8' das zweite Reinigungskompartiment 7' schließt. Im Anschluss daran kann wieder über ein Programm oder manuell über eine Zeitschaltuhr das Nachreinigungsprogramm gestartet werden, wobei auch hier eine einzelne Pumpe zur Förderung von Reinigungsmittel ausschließlich für diesen Schritt zuständig ist und dies auch entsprechend für den Ablauf des verwendeten eingesetzten Reinigungsmittels gilt, wie selbstverständlich auch für den vorherigen Vorreinigungsschritt im Reinigungskompartiment 7. Entsprechendes gilt auch für den jeweiligen Reinigungsmittelzulauf, sodass in diesem Fall der Reinigungsmittelzulauf für die einzelnen Reinigungskompartimente 7 und 7' jeweils unabhängige Reinigungsmittelzuläufe, unabhängige Reinigungsmittelabläufe sowie unabhängige Pumpen zur Förderung des Reinigungsmittels aufweisen.Afterwards, after opening the lid 8, the holder 2 together with the pre-cleaned objects 1, 3 are removed using a handle 6 (see Fig. Figure 2 ) is transferred to a second post-cleaning compartment 7', with the corresponding cover 8' closing the second cleaning compartment 7' at the start of the post-cleaning step. The post-cleaning program can then be started again using a program or manually using a timer be started, whereby here too a single pump for conveying cleaning agent is exclusively responsible for this step and this also applies accordingly to the flow of the cleaning agent used, as of course also for the previous pre-cleaning step in the cleaning compartment 7. The same applies to the respective cleaning agent inflow , so that in this case the cleaning agent inlet for the individual cleaning compartments 7 and 7 'each have independent cleaning agent inlets, independent cleaning agent drains and independent pumps for conveying the cleaning agent.

Mit erfindungswesentlich ist die Tatsache, dass für jeden Reinigungsschritt ein ausschließlich für diesen Reinigungsschritt vorgesehenes Reinigungskompartiment realisiert ist, wobei gleichzeitig der Halter bei jedem Reinigungsschritt in dem für den jeweiligen Reinigungsschritt vorgesehenen Reinigungskompartiment angeordnet ist, wobei der Halter nach einem ersten Reinigungsschritt vorgesehenen weiteren Reinigungskompartiment von diesem ersten Reinigungsschritt zugeordneten Reinigungskompartiment einem für einen weiteren Reinigungsschritt zugeführt wird, wobei die Zuführung automatisch, halbautomatisch, programmiert automatisch oder manuell durchgeführt werden kann.Essential to the invention is the fact that for each cleaning step a cleaning compartment intended exclusively for this cleaning step is realized, with the holder at the same time being arranged in the cleaning compartment provided for the respective cleaning step for each cleaning step, the holder being provided in a further cleaning compartment after a first cleaning step The cleaning compartment assigned to the first cleaning step is fed to a further cleaning step, wherein the feeding can be carried out automatically, semi-automatically, programmed automatically or manually.

Aufgrund dieser geschickten Merkmalskombination ist es möglich, dass sowohl minimaler Reinigungsmittelverbrauch bei ausgesprochen hohen Reinigungsleistungen erfindungsgemäß zu konstatieren ist, wobei gleichzeitig ein ausgesprochen geringer Zeitaufwand vonnöten ist aufgrund der systemischen Halterung der zu reinigenden Gegenstände 1, 3 innerhalb des Halters selbst.Due to this clever combination of features, it is possible that both minimal cleaning agent consumption and extremely high cleaning performance can be achieved according to the invention, while at the same time an extremely small amount of time is required due to the systemic holding of the objects 1, 3 to be cleaned within the holder itself.
