Description

Die Erfindung betrifft eine Waschvorrichtung für Druck- und/oder Beschichtungswerke in einer Verarbeitungsmaschine nach dem Oberbegriff von Anspruch 1.The invention relates to a washing device for printing and / or coating plants in a processing machine according to the preamble of claim 1.

Eine derartige Waschvorrichtung ist insbesondere in einer Druck- bzw. Beschichtungsmaschine, einschließlich einer Lackiermaschine, bzw. in Kombinationen aus Druck- und Lackwerken einer Verarbeitungsmaschine einsetzbar.Such a washing device can be used in particular in a printing or coating machine, including a coating machine, or in combinations of printing and coating units of a processing machine.

[Stand der Technik][State of the art]

Eine Waschvorrichtung dieser Art ist aus DE 91 15 948.2 U1 für die Reinigung eines Gummituchzylinders in einer Offsetdruckmaschine bekannt. Dabei ist die Waschvorrichtung mit einer Zuführleitung für das Reinigungsfluid und einer Rücklaufleitung mit nachgeordnetem Aufnahmebehälter für verschmutztes Reinigungsfluid verbunden. Das verschmutzte Reinigungsfluid fließt unter Einwirkung der Schwerkraft zu einem Aufnahmebehälter. Dem Aufnahmebehälter ist eine zu einer Filtereinrichtung führende Filterleitung nachgeordnet, in welcher eine Pumpe angeordnet ist. Die Filterleitung führt von der Filtereinrichtung weiter zu einem mit der Zuführleitung gekoppelten Vorratsbehälter. Der Aufnahmebehälter weist einen die Filterpumpe aktivierenden Niveauschalter auf und mittels der Filterpumpe wird das verunreinigte Reinigungsfluid durch die Filtereinrichtung getrieben.A washing device of this kind is made DE 91 15 948.2 U1 for cleaning a blanket cylinder in an offset printing machine. The washing device is connected to a supply line for the cleaning fluid and a return line with downstream receptacle for dirty cleaning fluid. The contaminated cleaning fluid flows under gravity to a receptacle. The receiving container is followed by a leading filter device to a filter line downstream, in which a pump is arranged. The filter line leads from the filter device on to a reservoir coupled to the supply line. The receptacle has a filter pump activating level switch and by means of the filter pump, the contaminated cleaning fluid is driven through the filter device.

Von Nachteil ist hierbei, dass die Abführung des verunreinigten Reinigungsfluides auf der Strecke von der Waschvorrichtung bis zum Aufnahmebehälter mittels Schwerkraft erfolgt und die Gefahr besteht, dass die Rücklaufleitung verstopfen kann. Die Beseitigung der Verstopfung ist aufwendig, da häufig die Rücklaufleitung gereinigt und möglicherweise demontiert werden muss.The disadvantage here is that the removal of the contaminated cleaning fluid on the route from the washing device to the receptacle is done by gravity and there is a risk that the return line can clog. The elimination of the blockage is expensive, since often the return line must be cleaned and possibly dismantled.

Aus US 5241908 A ist eine Reinigungsvorrichtung bekannt, bei der der Waschgehäuseboden mittels Druckluft gereinigt wird und anschließend werden die Verunreinigungen durch Unterdruck aus dem Gehäuse gesaugt und mittels eines am Gehäuse angeordneten Ejektors über eine Rücklaufleitung ausgetrieben. Nachteilig ist hierbei, dass der Unterdruck für eine stabile Reinigung häufig zu gering ist und ein hoher Luftverbrauch vorliegt. Ein möglicher Einsatz von Reinigungsfluid in einer derartigen Vorrichtung erscheint ungünstig.Out US 5241908 A a cleaning device is known in which the washing housing bottom is cleaned by means of compressed air and then the impurities are sucked by vacuum from the housing and expelled by means of a housing arranged on the ejector via a return line. The disadvantage here is that the negative pressure for stable cleaning is often too low and high air consumption is present. A possible use of cleaning fluid in such a device appears unfavorable.

[Aufgabe der Erfindung]OBJECT OF THE INVENTION

Der Erfindung liegt die Aufgabe zugrunde, eine Waschvorrichtung der eingangs beschriebenen Art zu schaffen, die die genannten Nachteile vermeidet, die zumindest in einem Druck-/Beschichtungswerk eine stabile Entsorgung von verschmutztem Reinigungsfluid gestattet und den Entsorgungs- bzw. Reinigungsaufwand spürbar reduziert.The invention has for its object to provide a washing device of the type described above, which avoids the disadvantages mentioned, which allows a stable disposal of contaminated cleaning fluid at least in a printing / coating and noticeably reduces the disposal or cleaning effort.

Gelöst wird die Aufgabe durch die Ausbildungsmerkmale von Anspruch 1. Weiterbildungen ergeben sich aus den Unteransprüchen.The problem is solved by the training features of claim 1. Further developments will become apparent from the dependent claims.

Ein erster Vorteil ist darin begründet, dass in einer Verarbeitungsmaschine mit vorzugsweise mehreren Druck- und/oder Beschichtungswerken zwischen den dort bevorzugt mehreren angeordneten Waschvorrichtungen und einem vorzugsweise zentralen Aufnahmebehälter in einem gemeinsamen Rücklaufleitungssystem zumindest eine Kolbenpumpe, vorzugsweise eine Axialkolbenpumpe, angeordnet ist. Diese Kolbenpumpe führt das verunreinigte Reinigungsfluid zumindest einem Aufnahmebehälter zu.A first advantage is due to the fact that at least one piston pump, preferably one axial piston pump, is arranged in a processing machine with preferably a plurality of pressure and / or coating units between the preferably arranged several washing devices and a preferably central receptacle in a common return line system. This piston pump supplies the contaminated cleaning fluid to at least one receptacle.

Dabei ist jeweils eine Kolbenpumpe jedem einzelnen Druck-/ Beschichtungswerk zugeordnet. Alternativ ist je eine Kolbenpumpe in Gruppen zusammengefassten, vorzugsweise benachbarten Druck- und/oder Beschichtungswerken zugeordnet.In each case, a piston pump is assigned to each individual printing / coating unit. Alternatively, one piston pump each is assigned to groups, preferably adjacent pressure and / or coating units.

Ein zweiter Vorteil besteht darin, dass an dieses mit vorzugsweise einer Axialkolbenpumpe gekoppelte Rücklaufleitungssystem die in Verarbeitungsmaschinen üblichen Waschvorrichtungen, beispielsweise Bürstenwaschvorrichtungen, rücklaufseitig ankoppelbar sind. Es sind dies insbesondere Farbwerkswalzenwaschvorrichtungen, Gummituchzylinderwaschvorrichtungen oder Formzylinderwaschvorrichtungen, Druckzylinderwaschvorrichtungen sowie Waschvorrichtungen für Dosiersysteme, einschließlich Kammerrakel-/ Auftragwalzensysteme. Derartige Waschvorrichtungen weisen am Gehäuse wenigstens eine Rücklaufleitung auf, welche direkt am Gehäuse anordenbar oder mit einem Gehäuseablauf koppelbar ist. Weiterhin sind auch mit einem Ablauf versehene Auffangwannen sowie Tropfbleche rücklaufseitig in die Rücklaufleitung eingebunden.A second advantage resides in the fact that the return line system, which is usually coupled to processing machines, for example brush washing devices, can be coupled to this return line system, which is preferably coupled to an axial piston pump. These are, in particular, inking roller washing machines, blanket cylinder washing machines or form cylinder washing devices, impression cylinder washing devices and washing systems for metering systems, including chambered doctor / applicator roller systems. Such washing devices have at least one return line on the housing, which can be arranged directly on the housing or can be coupled to a housing outlet. Furthermore, also provided with a drain collection trays and drip plates are integrated on the return side in the return line.

Alternativ ist die Kolbenpumpe direkt am Rücklauf (Ablauf) des Gehäuses der Waschvorrichtung, der Auffangwanne bzw. des Tropfbleches anordenbar. Bevorzugt ist zwischen Waschvorrichtung bzw. Auffangwanne/Tropfblech und Kolbenpumpe die Strecke der Rücklaufleitung kurz ausgelegt.Alternatively, the piston pump can be arranged directly on the return (drain) of the housing of the washing device, the drip pan or the drip plate. Preferably, the distance of the return line is designed short between washing device or drip tray / drip tray and piston pump.

Zumindest den Waschvorrichtungen ist gemeinsam, dass sie wenigstens eine Zuführleitung für ein Reinigungsfluid aufweisen.At least the washing devices have in common that they have at least one supply line for a cleaning fluid.

Dabei speisen die Waschvorrichtungen das beispielsweise durch Farb- bzw. Lackpartikel, Papierstaub, Puder etc. verunreinigte Reinigungsfluid in wenigstens eine gemeinsame, vorzugsweise.mit einer Axialkolbenpumpe gekoppelte Rücklaufleitung ein. Bei in Gruppen zusammengefassten Druck-/Beschichtungswerken mit vorzugsweise einer Axialkolbenpumpe ist bevorzugt eine parallele Anordnung der Rücklaufleitungen realisierbar. Hierbei ist jede Rücklaufleitung einzeln oder vorher zu einer gemeinsamen Rücklaufleitung vereinigt mit der zugeordneten Kolbenpumpe gekoppelt.The washing devices feed the cleaning fluid, which is contaminated, for example, by color or paint particles, paper dust, powder, etc., into at least one common return line, which is preferably coupled to an axial piston pump. For grouped together in groups printing / coating units with preferably an axial piston pump is preferably a parallel arrangement of the return lines feasible. Here, each return line is individually or previously coupled to a common return line combined with the associated piston pump.

Vorteilhaft ist weiterhin, dass bei diesem Rücklaufleitungssystem und der eingesetzten Kolbenpumpe Verstopfungen vermeidbar sind und dies auch bei geringen Mengen an Reinigungsfluid bzw. bei wenig fließfähigen Reinigungsfluiden. Somit ist eine stabile Entsorgung des verunreinigten Reinigungsfluides in jedem Druck-/Beschichtungswerk gewährleistet. Weiterhin sind bei diesen Ausbildungen der Aufwand für die Leitungsführung sowie der Entsorgungsaufwand für das verunreinigte Reinigungsfluid reduziert.A further advantage is that in this return line system and the piston pump used blockages are avoidable and this even with small amounts of cleaning fluid or less fluid cleaning fluids. Thus, a stable disposal of the contaminated cleaning fluid is guaranteed in each printing / coating unit. Furthermore, the expenses for the routing and the disposal costs for the contaminated cleaning fluid are reduced in these training.

Das Steuerventil 14 ist mit einer Luftversorgung 15 gekoppelt, vorzugsweise mit der Druckluftversorgung der Verarbeitungsmaschine. Bevorzugt ist das Steuerventil 14 weiterhin mit einer Maschinensteuerung 16, direkt am Druck- oder Beschichtungswerk 1,2 und/oder einer zentralen Steuerung der Verarbeitungsmaschine, schaltungstechnisch gekoppelt. Bevorzugt ist die Maschinensteuerung 16 schaltungstechnisch (Steuerleitung 19) mit jeder der im Druck-/Beschichtungswerk 1,2 eingesetzten Waschvorrichtungen 7.1 - 7.3 gekoppelt.The piston pump 12 is further coupled to pneumatically actuated supply lines 21, which are coupled to a control valve 14. The control valve 14 is coupled to an air supply 15, preferably to the compressed air supply of the processing machine. Preferably, the control valve 14 is further provided with a machine control 16, directly on the printing or coating unit 1,2 and / or a central control of the processing machine, circuit-coupled. Preferably, the machine control 16 is circuitically coupled (control line 19) to each of the washing devices 7.1 - 7.3 used in the printing / coating unit 1, 2.

Die Betätigung der Kolbenpumpe 12 ist nicht auf die pneumatische Betriebsweise beschränkt. Vielmehr ist ebenso eine elektrische Ansteuerung der Kolbenpumpe 12, vorzugsweise Axialkolbenpumpe, realisierbar. Hierbei ist die Kolbenpumpe 12 direkt mit der Maschinensteuerung 16 schaltungstechnisch gekoppelt. Alternativ ist ebenso eine hydraulische oder sonstige mechanische Betriebsweise realisierbar.The operation of the piston pump 12 is not limited to the pneumatic mode. Rather, an electrical control of the piston pump 12, preferably axial piston pump, can also be realized. Here, the piston pump 12 is coupled directly to the machine control 16 circuit technology. Alternatively, a hydraulic or other mechanical operation can be realized as well.

Von der Kolbenpumpe 12, vorzugsweise der Axialkolbenpumpe, führt ein zweiter Rücklaufstrang 22 zum Aufnahmebehälter 17 und mündet dort ein. Hierzu weist die Kolbenpumpe 12 ein zweites Ventil 13 (Öffner/Schließer) auf, welches in Verbindung mit dem aktivierten Kolben der Kolbenpumpe 12 den Weitertransport des verunreinigten Reinigungsfluides zum Aufnahmebehälter 17 bewirkt- Der Aufnahmebehälter 17 ist unmittelbar an der Verarbeitungsmaschine (stationär oder verfahrbar) oder zentral in einem Drucksaal anordenbar. Bei mehreren Verarbeitungsmaschinen ist ebenso eine Verkettung mit einer zentralen Aufbereitungs- oder Entsorgungsanlage für verunreinigtes Reinigungsfluid realisierbar.From the piston pump 12, preferably the axial piston pump, a second return line 22 leads to the receptacle 17 and opens there. For this purpose, the piston pump 12, a second valve 13 (opener / closer), which in conjunction with the activated piston of the piston pump 12 causes the further transport of the contaminated cleaning fluid to the receptacle 17- The receptacle 17 is directly on the processing machine (stationary or movable) or can be arranged centrally in a pressroom. In several processing machines, a concatenation with a central treatment or disposal system for contaminated cleaning fluid is also feasible.

Der Aufnahmebehälter 17 ist nicht auf einen Behälter beschränkt. Vielmehr sind mehrere untereinander verbundene bzw. untereinander austauschbare (Wechselbetrieb) Aufnahmebehälter 17 für die Aufnahme unterschiedlich verunreinigter Reinigungsfluide anordenbar. So ist beispielsweise ein Aufnahmebehälter 17 ausschließlich für die Sammlung eines Gemisches aus verunreinigtem Reinigungsfluid und UV-Lack, ein weiterer Aufnahmebehälter 17 für die Sammlung eines Gemisches aus verunreinigtem Reinigungsfluid und Dispersionslack oder ein weiterer Aufnahmebehälter 17 für die Sammlung eines Gemisches aus verunreinigtem Reinigungsfluid und Offsetfarbe einsetzbar.The receptacle 17 is not limited to a container. Rather, a plurality of interconnected or interchangeable (alternating operation) receiving container 17 for receiving differently contaminated cleaning fluids can be arranged. Thus, for example, a receptacle 17 exclusively for the collection of a mixture of contaminated cleaning fluid and UV varnish, another Receptacle 17 for the collection of a mixture of contaminated cleaning fluid and dispersion varnish or another receptacle 17 for the collection of a mixture of contaminated cleaning fluid and offset color can be used.

In einer Weiterbildung ist der Aufnahmebehälter 17 mit einer nachgeordneten, beispielsweise nach dem Sedimentationsprinzip oder nach dem Prinzip der Vakuumdestillation wirkenden, Aufbereitungsanlage 20 leitungsseitig verbunden.In a further development, the receptacle 17 is connected to the downstream side, for example, according to the sedimentation principle or according to the principle of vacuum distillation, processing plant 20.

Am Aufnahmebehälter 17 ist für die Niveauüberwachung bevorzugt eine Füllstandsmesseinrichtung 18 angeordnet. Bevorzugt wird bei Erreichen eines vorgegebenen Füllstandes von der Füllstandsmesseinrichtung 18 ein Steuersignal erzeugt. Hierzu ist die Füllstandsmesseinrichtung 18 schaltungstechnisch, hier mittels Steuerleitung 19, bevorzugt mit der Maschinensteuerung 16 gekoppelt. Das Steuersignal wird bevorzugt der Maschinensteuerung 16 zugeführt zwecks optischer bzw. akustischer Anzeige oder Abschalten der jeweils aktiven Waschvorrichtung 7.At the receptacle 17 preferably a fill level measuring device 18 is arranged for level monitoring. Upon reaching a predetermined fill level, the fill level measuring device 18 preferably generates a control signal. For this purpose, the level measuring device 18 circuitry, here coupled by means of control line 19, preferably with the machine control 16. The control signal is preferably fed to the machine control 16 for the purpose of optical or acoustic display or switching off of the respective active washing device 7.

In einer bevorzugten Weiterbildung erfasst die Füllstandsmesseinrichtung 18 zwei Füllstände im Aufnahmebehälter 17. Erstens den maximalen Füllstand, bei dessen Erreichen ein erstes elektrisches Signal an die Maschinensteuerung 16 und von dort an die jeweilige Waschvorrichtung 7 übermittelbar ist. Zweitens einen unter dem maximalen Füllstand liegenden, niedrigeren Füllstand, bei dessen Erreichen ein zweites elektrisches Signal an eine optische oder akustische oder sonstige Anzeigevorrichtung übermittelbar ist.In a preferred development, the fill level measuring device 18 detects two fill levels in the receptacle 17. First, the maximum fill level at which a first electrical signal is transmitted to the machine control 16 and from there to the respective wash device 7. Second, a lying below the maximum level, lower level at which a second electrical signal to an optical or acoustic or other display device can be transmitted.

Alternativ ist eine kontinuierliche Füllstandsmessung realisierbar, beispielsweise mittels einer Sonde zur Online-Erfassung des Füllstands zur Soll-/Istwert-Erfassung in schaltungstechnischer Kopplung mit der Maschinensteuerung.Alternatively, a continuous level measurement can be realized, for example by means of a probe for online detection of the level for setpoint / actual value detection in circuit technology coupling with the machine control.

In Fig. 2 ist in voller Linierung die Anordnung der Waschvorrichtungen 7 (7.1, 7.2, 7.3) mit Kolbenpumpe 12 und Aufnahmebehälter 17 pro Druck-/ Beschichtungswerk 1,2 gezeigt. In strichlierter Linierung ist zusätzlich die Einbindung einer weiteren Waschvorrichtung 7 (7.1, 7.2, 7.3) für ein weiteres, vorzugsweise benachbartes Druck-/ Beschichtungswerk 1,2 dargestellt. Damit ist ein gruppenweises Zusammenschalten der ersten Rücklaufstränge 11 mit nur einer Kolbenpumpe 12 realisierbar.In Fig. 2 is in full ruling the arrangement of the washing devices 7 (7.1, 7.2, 7.3) with piston pump 12 and receptacle 17 per printing / coating unit 1.2 shown. In dashed lines, the integration of a further washing device 7 (7.1, 7.2, 7.3) for a further, preferably adjacent, printing / coating unit 1, 2 is additionally shown. This is a group-wise interconnection of the first return strands 11 with only one piston pump 12 can be realized.

Die Ausbildung der Waschvorrichtung ist nicht auf das vorliegende Ausführungsbeispiel beschränkt.The construction of the washing apparatus is not limited to the present embodiment.

Alternativ ist zwischen jeder Waschvorrichtung 7; 7.1, 7.2, 7.3 und jeder Rücklaufleitung 11, 22 jeweils eine Kolbenpumpe 12 anordenbar. Die Kolbenpumpen 12 sind schaltungstechnisch mit der Maschinensteuerung 16 gekoppelt. Die Rücklaufleitungen 11, 22 sind mit wenigstens einer nachgeordneten, in einen Aufnahmebehälter 17 einspeisenden Sammelleitung verbunden. In die Sammelleitung bzw. Sammelleitungen speisen mehrere Rücklaufleitungen 11, 22 das verunreinigte Reinigungsfluid ein. Bei Verwendung unterschiedlicher bzw. untereinander unverträglicher Reinigungsfluide (bzw. Farben/Lacke) sind beispielsweise zwei Sammelleitungen, eine Sammelleitung für konventionelles Reinigungsfluid, eine Sammelleitung für UV-Reinigungsfluid, anordenbar. Diese Sammelleitungen speisen dann in getrennte Aufnahmebehälter 17 ein, um ein mögliches Vermischen zu vermeiden.Alternatively, between each washing device 7; 7.1, 7.2, 7.3 and each return line 11, 22 each a piston pump 12 can be arranged. The piston pumps 12 are circuit-coupled to the machine control 16. The return lines 11, 22 are connected to at least one downstream, in a receptacle 17 feeding manifold. In the manifold or manifolds feed several return lines 11, 22, the contaminated cleaning fluid. When using different or mutually incompatible cleaning fluids (or paints / coatings), for example, two manifolds, a manifold for conventional cleaning fluid, a manifold for UV cleaning fluid, can be arranged. These manifolds then feed into separate receptacles 17 to avoid possible mixing.

In einer weiteren Ausbildung sind mehrere Rücklaufleitungen 11, 22 leitungsseitig zusammenschaltbar und eine (einzige) mit der Maschinensteuerung 16 gekoppelte Kolbenpumpe 12 ist in eine der gekoppelten Rücklaufleitungen 11, 22 integriert. Die Rücklaufleitungen 11, 22 sind mit wenigstens einer nachgeordneten Sammelleitung leitungsseitig verbunden. Die Sammelleitungen speisen in wenigstens einen Aufnahmebehälter 17 ein. Je nach Bedarf speisen auch mehrere Sammelleitungen in getrennte Aufnahmebehälter 17 ein.In a further embodiment, a plurality of return lines 11, 22 can be interconnected on the line side and a (single) coupled to the machine control 16 piston pump 12 is integrated into one of the coupled return lines 11, 22. The return lines 11, 22 are connected to the line side with at least one downstream manifold. The manifolds feed into at least one receptacle 17. Depending on requirements, several manifolds feed into separate receptacles 17.

Die Wirkungsweise ist wie folgt:

  • Von den jeweils im Druck-/Beschichtungswerk 1,2 eingesetzten Waschvorrichtungen 7 (7.1, 7.2 7.3) wird das verunreinigte Reinigungsfluid in den ersten Rücklaufstrang 11 eingespeist.
Die Art der Einspeisung (z.B. mittels Schwerkraft, mittels Druckluft- bzw. Fluidunterstützung) ist beliebig. Der erste Rücklaufstrang 11 speist über das geöffnete erste Ventil 13 (Einlassventil) in den Druckraum der Kolbenpumpe 12, hier als Axialkolbenpumpe ausgebildet, das verunreinigte Reinigungsfluid ein. Dabei ist das zweite Ventil 13 (Auslassventil) geschlossen. Der Kolben der Kolbenpumpe 12 wird über die Maschinensteuerung 16 in Achsrichtung aktiviert und treibt das unter Druck stehende verunreinigte Reinigungsfluid aus dem Druckraum über den zweiten Rücklaufstrang 22 zum Aufnahmebehälter 17 aus. Hierzu ist das zweite Ventil 13 (Auslassventil) inzwischen geöffnet und das erste Ventil 13 (Einlassventil) ist geschlossen. Die Kolbenpumpe 12 ist über die Maschinensteuerung 16 periodisch im Pulsbetrieb betreibbar.
Durch Abluftdrosselung ist eine Kolbendämpfung an der Kolbenpumpe 12 realisierbar. Der im Druckraum anliegende Druck ist einstellbar, beispielsweise unter Berücksichtigung der Art des verunreinigten Reinigungsfluides, der Anzahl der Druck/Beschichtungswerke 1, 2, bzw. der Länge der Rücklaufleitung 11,22 .
Nach Beendigung des Waschprozesses bzw. vor einem Wechsel des Reinigungsfluides wird der Aufnahmebehälter 17 komplett entleert. Damit ist eine getrennte Entsorgung bzw. Wiederaufbereitung realisierbar.The mode of action is as follows:
  • Of the washing devices 7 (7.1, 7.2 7.3) used in each case in the printing / coating unit 1, 2, the contaminated cleaning fluid is fed into the first return line 11.
The type of feed (eg by gravity, by means of compressed air or fluid support) is arbitrary. The first return line 11 feeds the contaminated cleaning fluid via the open first valve 13 (inlet valve) into the pressure chamber of the piston pump 12, here designed as an axial piston pump. In this case, the second valve 13 (exhaust valve) is closed. The piston of the piston pump 12 is activated via the machine control 16 in the axial direction and drives the pressurized contaminated cleaning fluid from the pressure chamber via the second return line 22 to the receptacle 17 from. For this purpose, the second valve 13 (exhaust valve) is now open and the first valve 13 (inlet valve) is closed. The piston pump 12 is periodically operated by the machine control 16 in the pulse mode.
By exhaust throttling a piston damping on the piston pump 12 can be realized. The pressure applied in the pressure chamber pressure is adjustable, for example, taking into account the nature of the contaminated cleaning fluid, the number of pressure / coating units 1, 2, and the length of the return line 11,22.
After completion of the washing process or before a change of the cleaning fluid of the receptacle 17 is completely emptied. This is a separate disposal or reprocessing realizable.
