Abstract

A vacuum wrapping chamber is used to locate an unsealed cellophane bag which is full. The top wall of the vacuum chamber is flexible and is allowed to cover the bag inside the chamber by being in direct contact with it. When the air in the vacuum chamber is evacuated by pump, the heat sealing rail clamps the open end of the cellophane bag due to the force produced by the flexible chamber wall. Since most of the air is displaced by the flexible chamber wall before any suction is applied by the pump, this type of vacuum chamber is more efficient than rigid walled chambers.

Description

Patentanmeldung: Flexible Kammer für Vakuum-Verpackungs-Patent application: Flexible chamber for vacuum packaging

gerät vom: 25. Februar 1977 Firma: Arthur Ess, Elektromaschinen und Apparatebau, 7967 Bad Waldsee Die Erfindung betrifft eine Absaug-Kammer, die zum größten Teil aus einem flexiblen Werkstoff 1 besteht. device dated: February 25, 1977 Company: Arthur Ess, Elektromaschinen und Apparatebau, 7967 Bad Waldsee The invention relates to a suction chamber that is used for consists mostly of a flexible material 1.

Bis jetzt werden Vakuum-Verpackungsgeräte mit festen Absaug-Kammern 10 verwendet.Until now, vacuum packaging devices have been made with fixed suction chambers 10 used.

Dieses feste Kammersystem hat den Nachteil, daß jeweils das ganze Kammervolumen 12 evakuiert werden muß. Das heißt, also auch jenes, welches durch das jeweilige Verpackungsgut 11 nicht belegt ist.This fixed chamber system has the disadvantage that each of the whole Chamber volume 12 must be evacuated. That is to say, also that which through the respective packaged item 11 is not occupied.

Außerdem müssen feste Kammern 10 mechanisch stabiler ausgelegt werden als flexible.In addition, fixed chambers 10 must be designed to be mechanically more stable as flexible.

Der Zweck der flexiblen Kammer 1 ist, die Absaugleistung der erforderlichen Vakuumpumpe 4 gegenüber den bis jetzt bekannten Vakuum-Verpackungsgeräten bei gleicher Verpackungskapazität wesentlich zu verringern.The purpose of the flexible chamber 1 is to increase the suction power required Vacuum pump 4 compared to the previously known vacuum packaging devices with the same Significantly reduce packaging capacity.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Kammer ganz oder zum Teil aus einem flexiblen Werkstoff 1 besteht.This object is achieved according to the invention in that the chamber consists entirely or in part of a flexible material 1.

Um einen einwandfreien Anpressdruck der Schweißleiste 2 auf die Schweißnaht 3 zu erhalten, drückt der flexible Teil der Kammer beim Endvakuum auf die Schweißleiste 2 und damit auf die Schweißnaht 3.To ensure perfect contact pressure of the sealing bar 2 on the weld seam 3, the flexible part of the chamber presses on the sealing bar at the ultimate vacuum 2 and thus on the weld 3.

Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, daß die Pumpenauslegung wesentlich kleiner ist und somit auch die Bauform und der Preis.The advantages achieved with the invention are in particular: that the pump design is much smaller and thus also the design and the Price.

Während bei den bisher bekannten, festen Absaug-Kammern das abzusaugende Volumen immer jenes war, welches aus dem Kammervolumen 12 inclusive der Luit im Verpackungsbeutel 13 abzüglich dem Verpackungsgut 11 resultiert, wird bei der flexiblen Kammer 1 das tatsächlich zu evakuierende Volumen wesentlich reduziert und damit die erforderliche VakUumpumpen-Kapazität.While in the previously known, fixed suction chambers that to be suctioned off Volume was always that, which from the chamber volume 12 including the Luit im Packaging bag 13 minus the packaging material 11 is the result of the flexible Chamber 1 significantly reduces the volume to be evacuated and thus the required vacuum pump capacity.

Beisniele: 1. Feste Kammer: Volumen = 90 1 300 x 300 x 100 mm ./. Verpackungsvolumen - 2 1 Zu evakuieren sind = 88 1 2. Flexible Kammer: Volumen - 18 1 300 x 300 x 20 mm ./. Verpackungsvolumen - 2 1 Zu evakuieren sind - 16 1Examples: 1. Fixed chamber: Volume = 90 1 300 x 300 x 100 mm ./. Packaging volume - 2 1 To be evacuated = 88 1 2. Flexible chamber: Volume - 18 1 300 x 300 x 20 mm ./. Packaging volume - 2 1 Must be evacuated - 16 1
