Description
FESTFRIERGREIFERFREEZER PULLER
Beim HJrldhaben von Gegenständen ist es häufig notwendig, Greifer einzusetzen. Bekannt sind Backen- und Fingergreifer sowie Saug-, Hdft- und Magnetgreifer. Diese Greifer haben Nachteile, da sie nur bedingt einsetzbar sind: Bei den Backen- und Fingergreifern müssen die Gegenstände positioniert im Greifbereich sein; beim Sauggreifer muß vorausgesetzt werden, daß die Oberfläche des zu greifenden Teils eben und ohne Poren (Löcher) ist und die Greifstelle so positioniert wird, daß ein Luftabschluß des Greifmechanismus entsteht; Haftgreifer haben den Nachteil, daß Adhasionsschichten durch Verschmutzung ihre Wirksamkeit schnell verlieren; Magnetgreifer setzen magnetische Gegenstände zum Greifen voraus.When handling objects, it is often necessary to use grippers to use. Jaw and finger grippers as well as suction, handheld and magnetic grippers are known. These grippers have disadvantages because they can only be used to a limited extent: and finger grippers, the objects must be positioned in the gripping area; at the It must be assumed that the surface of the part to be gripped is flat and without pores (holes) and the gripping point is positioned so that a Air exclusion of the gripping mechanism arises; Adhesive grippers have the disadvantage that Adhesion layers quickly lose their effectiveness due to contamination; Magnetic gripper require magnetic objects to grasp.
Beim Festfriergreifer werden diese Nachteile weitgehend vermieden.These disadvantages are largely avoided with the freezer grabber.

stand aufgedrückt und die Greiffläche unter den Gefrierpunkt der Benetzungs-1 35 gkeit abgekühlt, so entsteht zwischen der Gegenstandoberfläche und dem Greifer eine kraftschlüssige Verbindung. Durch Erwärmen ist die Verbindung zu lösen.stood pressed and the gripping surface below the freezing point of the wetting 1 35 cooling, this is created between the surface of the object and the gripper a positive connection. The connection can be loosened by heating.
Der Flüssigkeitsfilm muß auf das Material der Gegenstandsoberfläche abgestimmt sein. Er muß die Oberfläche benetzen, darf diese jedoch in der Regel chemisch nicht verändern.The liquid film must be on the material of the object surface be coordinated. It has to wet the surface, but is usually allowed to do so do not change chemically.
Die Abb. 1 zeigt ein Beispiel eines Festfriergreifers.Fig. 1 shows an example of a freezing grabber.
In dem rundsvmmetischen Körper 3 befindet sich eine Expansionskammcr 4.In the rounded body 3 there is an expansion chamber 4th
Durch den Eingang 1 wird vorgespanntes Kühlmittel eingelassen, welches im entspannten Zustand durch die Öffnung 2 entweicht. Durch den Entspannungsprozeß entsteht in der Expansionskammer 4 eine niedrige Temperatur.Pre-stressed coolant is admitted through input 1, which escapes through opening 2 in the relaxed state. Through the relaxation process a low temperature arises in the expansion chamber 4.
Insbesondere der Greiferboden 5 wird wegen seiner guten Wärmeleitung die niedrige Temperatur schnell annehmen und es wird sich eine Kondenswasserschicht bilden. Der Boden 5 wird auf das zu greifende Teil aufgesetzt, dessen Oberfläche zunächst noch relativ warm ist, so daß die Eisschicht kurz auftaut und danach sofort anfriert. Das Teil ist somit gegriffen. Zum Abwerfen des Teils wird zweckmäßig durch die Öffnung 1 warme Luft geblasen.In particular, the gripper base 5 is because of its good heat conduction accept the low temperature quickly and there will be a layer of condensation water form. The bottom 5 is placed on the part to be gripped, its surface is initially still relatively warm, so that the ice layer thaws briefly and then immediately freezes. The part is gripped. To eject the part is expedient by the opening 1 blown warm air.
