Abstract:
The invention relates to a packaging machine (1), which comprises a control unit (2), at least one measurement device (5) and a plurality of work units (3) for different processes, wherein one of the work units is designed as a sealing station (17) which comprises at least one moisture sensor (F5) designed as the measurement device (5) which is functionally connected to the control unit (2) and is designed to detect moisture within the sealing station (17) as a time-dependent measured variable during a program sequence (P) of the sealing station (17), wherein the program sequence (P) comprises an evacuation process, wherein the control unit (2) is designed to calculate a rate of change in the moisture during the evacuation process of the sealing station (17), and wherein the control unit (2) is designed to abort the evacuation process performed on the sealing station (17), based on the rate of change, before reaching a target vacuum pressure within the sealing station (17), immediately or after a specified delay time elapses.
Abstract:
The invention relates to a method for determining the curing behaviour of an adhesive- or sealant bead (10), said adhesive- or sealant bead (10) being applied to a workpiece (12). Multiple test bodies (26) are placed on the adhesive- or sealant bead (10) at different, pre-defined placement times and deformations of the adhesive- or sealant bead (10), caused by the test bodies (26), are measured at a pre-defined end time.
Abstract:
Die Erfindung bezieht sich auf ein Verfahren zum Versiegeln von Verpackungsmaterial (6) und eine Kammermaschine oder Kammerbandmaschine (1) zur Durchführung des Verfahrens zum Vorwärmen wenigstens einer Siegelschiene (9) auf eine erste Temperatur (T1), um im Siegelbereich (12) vorhandene flüssige, vorzugsweise wasserhaltige, Produktanteile (11) vor dem Versiegeln entweichen zu lassen.
Abstract:
A system for continuously and configurationafly heat soldering layered sheets of plastic, concomitantly with embossing a distinctive pattern across at least one face of the heat soldered seam. The disclosed system has at least one pressing face that includes the mirror image of the pattern to be embossed across a face of the seam, engraved therein. Pressing faces embedding electrical heaters provide for embossing a changeable content across the faces of the seam. Sealing band a pattern engraved across a face of which provides according to the present invention for embossing distinct three-dimensional geometrical shapes across the faces of the heat-soldered seams. A seam that is heat soldered according to the present invention continuously extends across two-dimensional contours of significant widths. Three-dimensional features having distinct sectional shapes protrude off the seam at least towards one direction. Bulges protruding towards two opposing directions as well as recesses their apertures facing two opposing directions are positioned within the soldered region of the seam. Sealing dies providing for heat soldering a cover made of thin foil of plastic such as polyethylene to the sidewalls of receptacle such as cup pack is also provided.
Abstract:
In a case where an operator stops operation of a pedal, a CPU drives an air cylinder (105) and moves a second pulley (28) from a first position to a second position. When the second pulley moves to the first position, a movable portion (58) of the air cylinder moves downward. A front portion of a belt (27) moves upward. In the first position, the belt and a nozzle (17) clamp a lower cloth (152). When the second pulley moves to the second position, the movable portion of the air cylinder moves upward. The front portion of the belt moves downward. In the second position, the second pulley is separated further from the nozzle than in the first position. Thus, a gap between the lower cloth and the nozzle becomes wider.
Abstract:
Die Erfindung betrifft ein Verfahren zum Erzeugen einer Schweißkraft bzw. eines Schweißdruckes für eine Schweißbacke (1,6), insbesondere eine Schweißbacke (1,6) einer Quersiegelstation (2) einer vertikalen Schlauchbeutelmaschine (3), bei dem die Siegelkraft oder ein mit der Siegelkraft korrelierender Siegelparameter, insbesondere der Siegeldruck oder die Antriebsleistung des Antriebs, von einer Steuereinrichtung während der Siegelzeit derart vorgegeben wird, dass die Siegelkraft innerhalb der Siegelzeit entlang einer Siegelkraftkurve (32) verläuft, wobei die Siegelkraftkurve (32) ein erstes relatives Siegelkraftmaximum (33) mit einer Siegelkraft und zumindest ein zweites relatives Siegelkraftmaximum (34) mit einer Siegelkraft aufweist, wobei die Siegelkraft beim ersten Siegelkraftmaximum (33) höher ist als die Siegelkraft beim zweiten Siegelkraftmaximum (34).
Abstract:
A system for providing power to more than one ultrasonic welding probe from a single power supply. The system includes a first multiple probe subassembly having a first jack for connection to a first ultrasonic welding probe and a second jack for connection to a second ultrasonic welding probe. The system also includes a second multiple probe subassembly having a third jack for connection to a third ultrasonic welding probe and a fourth jack for connection to a fourth ultrasonic welding probe. At least one connector connects the first multiple probe subassembly to the second multiple probe subassembly.
