摘要:
Die Erfindung betrifft eine Vorrichtung (1) zum Abtrennen von einzelnen flachen, biegbaren Gegenständen (2) von der Unterseite eines Stapels (30) solcher Gegenstände (2). Die Vorrichtung enthält einen Stapelraum (31) mit einem Stützbereich (12), eine den Stapel (30) im Stützbereich (12) von unten stützende Rollenanordnung aus einer Mehrzahl von umlaufenden Rollen (9) sowie Abtrenn- und Haltemittel (4, 5) zum Abtrennen der Gegenstände (2) von der Unterseite des Stapels (30). Die Rollen (9) der Rollenanordnung sind entlang einer Umlaufbahn (11) geführt im Stützbereich (12) unter dem Stapel (30) vorbei bewegbar. Die Vorrichtung (1) enthält ferner eine Unterstelleinrichtung (32) mit einem Unterstellmittel (33) zum Positionieren des Unterstellmittels (33) in einer Halteposition zwischen dem Stapel (30) und den Rollen (9) der Rollenanordnung.

摘要:
The invention is based on the recognition that by a systematic data processing of returned newspapers, which carry a bar code identifying the daily edition number and/or the sales district, it will be possible to plan the production and the distribution for minimizing the returnings. However, in practice this will require the use of a destacker which can operate with a very high capacity and handle papers of widely different thicknesses. Previous destackers have had to be adjusted to a specific paper thickness when a high operation speed is required, e.g. 3-6 copies per second. The invention provides for a destacker which can operate at high speed with both thick and thin copies, based on the clamping parts (28,30) gripping the single copies (22) and drawing these out from the bundle with high speed are held together by the use of a suitably high spring force with a pronounced soft spring characteristic, preferably by the use of compressed air cylinders (52).

The present invention relates to the field of object packaging, such as, for example, bottles or other containers. Particularly, the invention relates to a sheet separator machine for cartons for packaging from a warehouse, typically a well warehouse, in which the cartons are stacked. Particularly, the present invention relates to a machine (1) for separating sheets of cartons (C), comprising a frame (2) on which a handling station (3) of the cartons (C), a warehouse (4) for at least one stack of cartons (C), and a gripping station (5) of the cartons (C), are mounted, in an operatively contiguous position, in which the gripping station (5) comprises a pair of counter-rotating motorized rolls (41, 42), suitable to withdraw a carton from said at least one stack of cartons (C).

The invention relates to a method and an arrangement for conveying packaging blanks (3) from a stack of blanks in a magazine (2) to a form chamber (4) in an erecting machine (1), where the blanks are erecting into packaging containers with the aid of a plunger (5). At least one suction cup device (8) with a vacuum operated suction cup, which attaches itself to the outmost blank (3) in the magazine (2) at the upper portion (9) of the blank, takes it, after swinging it outwards, into engagement with at least one bolster roller (10) situated in association with the exit end (6) of the magazine (2), in which position of the blank at least one segment device (18) swings to press the blank against the roller (10) with the same rotational speed at which the roller rotates, thus pressing the blank (3) between roller and segment such as to advance the blank over the roller, the blank then going from a substantially vertical attitude in the magazine (2) to a substantially horizontal attitude in front of the form chamber (4) in the erecting machine (1).

摘要:
In terms of their operational reliability, apparatuses for discharging from a magazine of flat-laid packaging container blanks of the type used for manufacturing packaging containers for liquid contents are greatly dependent upon the quality of the packaging container blanks themselves. In the event of varying friction or abutment pressure between the packaging container blanks, there is a risk that more than one blank is discharged at a time, or alternatively that no blank is discharged at all. In order to ensure a dependable function with repeated discharge of one blank at a time and at a predetermined rate, the apparatus according to the present invention includes a pivotal lever (9) provided with a suction cup or cups (11), the lever displacing one packaging container blank (5) at a time from the discharge end of a magazine past a segmented wheel which grasps the discharged blank (5) between a rubber cladding (15) and a counter wheel (13) for further advancement to a conveyor (21).
