Abstract
Description
Beim sog. Airless- oder Airmix- (bzw. Airassistant-) Spritzen wird das zu sprühende Material durch relativ hohen Material druck mit Hilfe einer speziellen Düse zerstäubt.With so-called Airless or Airmix (or Airassistant) spraying the material to be sprayed is made of relatively high material pressure atomized using a special nozzle.
Um diese Zerstäubung zu erreichen, muß die Düse bestimmte Kriterien erfüllen, d.B. eine relativ kleine Düsenbohrung auf weisen (0,15-1,2 mm). Speziell durch diese kleine Düsen bohrung ergibt sich ein großes Problem bei dieser Art Spritz verfahren, nämlich das Verstopfen der Düsen (z.B. durch Schmutzpartikel, kleine Materialverklumpungen u.ä.).In order to achieve this atomization, the nozzle must be certain Meet criteria, i.e. a relatively small nozzle bore point (0.15-1.2 mm). Especially through these small nozzles drilling is a major problem with this type of spray procedure, namely clogging of the nozzles (e.g. through Dirt particles, small clumps of material, etc.).
Zur Beseitigung der Verstopfer, d.h. zur Reinigung der Düsen, haben sich in den letzten Jahren drei Systeme eingebürgert:To remove the blockages, i.e. for cleaning the nozzles, three systems have become common in recent years:
- 1. Ein sog. Düsendrehkopf in den verschiedensten Ausführun gen.1. A so-called nozzle turret in various designs gene.
- Hierbei wird die Düse von Hand um z.B. 180 Grad gedreht; dadurch ist der Verstopfer in Fließrichtung gesehen nach vorne. Wenn jetzt die Pistole von Hand betätigt wird, wird der Verstopfer durch das unter hohem Druck strömende Material ausgetragen. Danach wird die Düse von Hand wieder zurückgedreht und ist (bis zum nächsten Verstopfer) wieder spritzbereit.Here the nozzle is moved by hand e.g. Rotated 180 degrees; this means that the blocker is seen in the direction of flow Forward. If the pistol is now operated by hand, the blockage is caused by the flowing under high pressure Material discharged. After that, the nozzle is hand again turned back and is (until the next clog) again ready to spray.
- 2. Sog. Verstelldüsen, die es erlauben, die Düsengröße mechanisch von Hand zu verstellen.2nd suction Adjustable nozzles that allow the nozzle size mechanically adjustable by hand.
- Hier wird bei Verstopfern die Düsenöffnung so weit ver größert, daß die Verstopfer durch den hohen Materialdruck ausgepreßt werden können.In the case of blockages, the nozzle opening is so far ver enlarges that the blockers by the high material pressure can be squeezed out.
- 3. Schnellwechseldüsen, die durch spezielle Techniken beim Verstopfen einfach gegen eine saubere Düse ausgewechselt werden können.3. Quick-change nozzles, which by special techniques at Simply replace the clog with a clean nozzle can be.
Im Zeitalter der Automation ergibt sich das Problem, die Rei nigung verstopfter Düsen ebenfalls zu automatisieren.In the age of automation, the problem arises, the rei automation of clogged nozzles.
Zur Lösung dieses Problemes gibt es z.Zt. nur eine Ausführung zur Düse lt. System 2. Dabei wird eine Verstelldüse mit einem kleinen pneumatischen Hubzylinder ausgerüstet, der bei Ver stopfungen die Düsenbohrung auf Maximum vergrößert und dann wieder auf die ursprüngliche Stellung zurücksetzt.To solve this problem, there are currently only one version to the nozzle according to system 2. Here an adjustment nozzle with a small pneumatic lifting cylinder equipped with Ver the nozzle bore to maximum and then returns to the original position.
Da aber häufig die Verstopfer durch Partikel erzeugt werden, die größer als der Düsendurchmesser sind, hilft diese Lösung nicht immer.But since the blockers are often generated by particles, larger than the nozzle diameter helps this solution not always.
Es wurde eine Mechanik entwickelt, die in der Lage ist, das Drehen der Düse um 180° (bzw. 90°) automatisch durchzuführen. Hierdurch ist es möglich, verstopfte Düsen ohne größeren Zeit verlust sowie ohne Aufwand an Wartungspersonal automatisch zu reinigen.Mechanics have been developed that are able to do this Rotate the nozzle automatically by 180 ° (or 90 °). This makes it possible to clear clogged nozzles without much time loss and automatically without maintenance personnel clean.
Wie unter dem Stichwort Problemlösung aufgeführt, wurde eine Mechanik entwickelt, um die zur Reinigung einer Airless-/ Airmixdüse erforderliche Drehung der Düse bzw. des Düsen trägers um 180° zu ermöglichen.As listed under the keyword problem solving, a Mechanics developed to clean an airless / Airmix nozzle required rotation of the nozzle or nozzles carrier by 180 °.
Diese automatische Drehung kann je nach Roboter- bzw. Automaten system elektrisch, hydraulisch oder pneumatisch über die ent sprechende Mechanik angetrieben werden.This automatic rotation can vary depending on the robot or machine system electrical, hydraulic or pneumatic via the ent speaking mechanics are driven.
Hierdurch wird aus einem Spritzautomaten (z.B. Roboter) ein wirklicher Automat, da die täglich ein- oder mehrmals auftreten den Düsenverstopfer automatisch beseitigt werden können. Bisher war hierzu immer der Einsatz von Wartungspersonal nötig, um die Drehbewegung von Hand durchzuführen. This turns an automatic spray gun (e.g. robot) into a real automaton, because they occur one or more times a day the nozzle blocker can be automatically removed. So far, the use of maintenance personnel has always been necessary for this, to perform the rotary movement by hand.
Durch den Einsatz des automatischen Düsendrehkopfes, d.h. durch die automatisierte Drehung der Düse bei Verstopfern, sind wirtschaftlich enorme Zeiteinsparungen und Kostensen kungen beim Wartungsaufwand möglich.By using the automatic nozzle turret, i.e. through the automated rotation of the nozzle in the event of blockages, are economically enormous time savings and cost savings Maintenance work possible.
