摘要:
There is described a packaging apparatus (1) comprising a tube forming and sealing device (5), a filling device (7), a product delivery device (8) configured to receive a pourable product from an external product supply (9) and to selectively feed the pourable product along a flow path to and into the filling device (7) and a package forming unit (10) configured to at least form and transversally seal the tube (3) for forming packages (2) filled with the pourable product. The product delivery device (8) comprises a main inlet valve (30) having a first inlet (31) and a first outlet (32) and a control valve (33) arranged downstream from the main inlet valve (30) and upstream from the filing device (7) along the flow path and having a second inlet (34) and a second outlet (35). The main inlet valve (30) comprises a first valve element (42) controllable into at least a closing position, an opening position and one or more intermediate positions. Additionally or alternatively, the control valve (33) comprises a second valve element (44) being controllable into a closed position and an open position.

Método de envasado en el que se suministra un tubo (10) en una dirección de avance (A), que comprende una etapa de plegado en la que se actúa sobre dicho tubo (10), transversal a la dirección de avance (A), plegando una parte del tubo (10) en una dirección de plegado (T), y una etapa de sellado y corte tras la que se obtiene un tubo (10) cerrado por un extremo, y un envase cerrado y separado del tubo (10). Durante la etapa de plegado se sujeta el tubo (10) transversalmente, y se genera una rotura en la dirección de plegado (T) entre las partes actuada y sujeta del tubo (10). El tubo (10) se sella a ambos lados de la rotura y se corta a la altura de la rotura. Máquina de envasado adaptada para aplicar el método.

Die Erfindung betrifft eine Vorrichtung zur Herstellung einer Verpackung (20) aus einer Packstoffbahn, umfassend ein Formrohr (2), ein teilweise durch das Formrohr verlaufendes Füllrohr (11), eine am Formrohr (2) angeordnete Formschulter (3) zum Formen eines Hüllstoffschlauchs, eine Faltvorrichtung (7), welche in Förderrichtung (A) des Hüllstoffschlauchs nach der Formschulter (3) angeordnet ist, und eine Siegelvorrichtung (6) mit einer Vielzahl von Siegeleinheiten (6a, 6b), welche in Förderrichtung (A) des Hüllstoffschlauchs nach der Faltvorrichtung (7) angeordnet sind, wobei das Formrohr (2) einen ersten Durchmesser (D1 ) aufweist und das Füllrohr (11) einen zweiten Durchmesser (D2) aufweist, wobei der erste Durchmesser (D1) größer als der zweite Durchmesser (D2) ist, wobei die Faltvorrichtung (7) am Ende des Formrohrs (2) angeordnet ist, und wobei die Faltvorrichtung (7) ein parabelförmiges Faltelement (8) aufweist, um Falten am Hüllstoffschlauch zu formen, wobei das parabelförmige Faltelement (8) derart angeordnet ist, dass ein Scheitelpunkt (9) des parabelförmigen Faltelements (8) entgegen der Förderrichtung (A) gerichtet ist.
摘要:
Described is a machine (5) for making and packaging articles (1) containing infusion product, the machine (5) being of the type defined by a production line (A) comprising a plurality of operating stations located one after the other and designed to make at least one continuous strip (S) by superposing and sealing two webs of filter paper with measured quantities or charges (4) of infusion product interposed between them at regular intervals; and at least one cutting station (6) for dividing up the strip (S) to form a succession of individual articles (1). The machine (5) further comprises at least one built-in packaging station (8, 8a) for packaging groups of the articles (1) in bag-like packets (10). The built-in packaging station (8, 8a) is located immediately downstream of the cutting station (6) and comprises a packaging device (9) for making up stacks (la, lb) with the articles (1) and 15 a transfer device (11) which guides the stacks (la, lb) of articles (1) along a vertical feed path section (Z) transversal to the production line (A) and feeds them into the bag-like packets (10) .
摘要:
Device for controlling the descent of delicate products inside the forming tube of a vertical packaging machine CHARACTERISED IN THAT it comprises at least a length of vertical conveyor belt (1) inserted inside the forming tube (2) and equipped with a shelf (3) that is integral with the belt and turns downward on reaching the leveI of the lower return roller (4) so as to allow the gradual transfer of products in proxility to the bottom (5) of the bag to be filled (6).
摘要:
In a vertical form, fill, seal machine (10) that produces liquid-filled stand-up pouches, a flat vertical seal tube (26) is surrounded by an envelope of thermoplastic film (28) that is closed along one longitudinal edge (34) and open along the opposite longitudinal edge (36). A main drive assembly (54) includes drive members (56) that press opposite sides of the envelope (28) against the flat fill tube (26). An auxiliary film drive assembly is responsive to film tension. Stand-up base cups (B) are formed seriatim along the closed longitudinal edge (34) of the envelope (28). Fitments (F) are inserted seriatim into the open longitudinal edge (34), in correspondence with respective cups (B), and are sealed to the thermoplastic film (28), first by a spot sealer and then by a top sealer.
