A device for filling and closing disposable bags for containing banknotes comprises an upper container (11) for temporarily housing banknotes (12), provided with a bottom (15) with an opening (19) for the exit of the banknotes (12) from the container (11), a piston (14) for pushing the banknotes (12) towards the opening (19) on the bottom of the container (11), a bag (13) made of flexible plastic film, intended to be filled with the banknotes temporarily housed in the container (11), a support (16) for the bag (13) containing the banknotes, vertically movable through controlled lowering means (17) and placed below the container (11), sealing bars (18) arranged between the upper container (11) and the movable support (16), intended to seal the mouth of the bag (13) upon completing the filling, and an electromagnetic stop element (26) that can be controlled to lock the movable support (16) with respect to the sealing bars (18), said electromagnetic stop element consisting of an electromagnet (27) applied to the movable support (16) and of a fixed element (28) made of ferromagnetic material, adapted to face the electromagnet (27) in operative condition.
摘要:
Die Erfindung betrifft ein Verfahren zum Verpacken von Gegenständen und/oder Objekten, bei dem die Gegenstände in einem elastischen Verpackungsmaterial verpackt werden und das elastische Verpackungsmaterial zum Verpacken der Gegenstände während des Verpackungsvorganges gedehnt wird. DasVerpackungsmaterial wird hierzu in einem Behältnis (1) angeordnet, in dem ein Unterdruck erzeugt wird. Durch Einwirken des äußeren Luftdruckes auf das Verpackungsmaterial wird das Verpackungsmaterial gedehnt. Anschließend wird das zu verpackende Gut (19) in oder auf dem Verpackungsmaterial angeordnet. Nach Aufheben des Unterdruckes stellt sich das Verpackungsmaterial durch seine Elastizität selbsttätig zurück und legt sich an das zu verpackende Gut an. Darüber hinaus betrifft die Erfindung eine Vorrichtung zur Durchführung des Verfahrens.
摘要:
A gripping apparatus associable to a wrapping machine and arranged to grip and retain an end flap of a film wrapped around a load at the end of a wrapping process, comprises pliers which include a first lever and a second lever that are hinged around a first axis and provided respectively with a first jaw and a second jaw suitable to tighten the film in a gripping position, a supporting arrangement for supporting the pliers and an actuator device fixed to the supporting arrangement and arranged to move the pliers between the gripping position and a releasing position, in which the jaws are spaced apart; the first lever comprises a first connecting end that is opposite to the first jaw and rotatably fixed to the supporting arrangement and the second lever comprises a second connecting end that is opposite to the second jaw, rotatably connected to the actuator device and linearly actuated by the latter along a first displacement direction in such a manner that the jaws are mobile around the first axis, along said first displacement direction and along a second displacement direction transversal to said first displacement direction.

An apparatus for packaging stacks of folded tissue products or the like with blanks of plastic film is disclosed. The apparatus comprises at least one pocket (58) comprising a plurality of side walls disposed within a drum having a longitudinal axis, a plurality of adjacent grooves 62 disposed upon the side walls within the pocket, insertion means for inserting (5) a single stack (3) in the pocket, along an insertion direction, with the interposition and consequent folding of a corresponding blank (38), and control means adapted to drive the stop means along the insertion direction in a coordinated manner with respect to the operation of the insertion means.
摘要:
A bagger comprising: i) forming means (200) for forming a bag that is apt for receiving a product to be bagged, said forming means (200) comprising: - a forming body (2) that is apt for passing inside a first tubular tract (3) that is intended to create said bag; - closing means (6) for closing at least one edge of said first tubular tract (3);
ii) gripping means (4) for gripping the forming body (2) and comprising at least a first and a second supporting means (41, 42) for supporting the forming body (2); said first supporting means (41) gripping the forming body (2) upstream of the second supporting means (42) with respect to the feed direction of the first tubular tract (3). In a first configuration, the first and the second supporting means (41, 42) perform their gripping action on the forming body (2), whereas in a second configuration, the first supporting means (41) does not carry out a gripping action on the forming body (2) so as to permit passage of the first tubular tract (3), while the second supporting means (42) performs its gripping action on the forming body (2).
