Abstract
Dispositivo applicabile a macchine confezionatrici a tubo formatore caratterizzato dall'intervento di un equipaggio ausiliario (9) che, durante la formazione del sacchetto ne piega il lembo (4) della termosaldatura trasversale sporgente dal fondo (3) del sacchetto (2) e lo fissa bloccandolo contro la zona (10) della parete di fondo, la quale così spianata potrà consentire alla confezione di assumere stabilmente un assetto verticale su un piano di appoggio orizzontale.Device applicable to forming tube packaging machines characterized by the intervention of an auxiliary crew (9) which, during the formation of the bag, folds the flap (4) of the transverse heat sealing projecting from the bottom (3) of the bag (2) and fixes it locking it against the area (10) of the back wall, which thus flattened will allow the package to assume a stable vertical position on a horizontal support surface.
Description
DESCRIZIONE annessa alla domanda di brevetto per invenzione industriale avente per titolo "DISPOSITIVO APPLICABILE A MACCHINE CONFEZIONATRICI A TUBO FORMATORE PER PIEGARE IL LEMBO DEL FONDO DEL SACCHETTO IN FORMAZIONE E BLOCCARLO ALLA PARETE DI FONDO PER TERMOSALDATURA O CON COLLA DESCRIPTION attached to the patent application for industrial invention entitled "DEVICE APPLICABLE TO FORMING TUBE PACKAGING MACHINES FOR FOLDING THE BOTTOM OF THE BAG IN FORMATION AND BLOCKING IT TO THE BOTTOM WALL FOR HEAT-SEALING OR WITH GLUE
CAMPO DELLA TECNICA FIELD OF TECHNIQUE
La presente invenzione si riferisce alla tecnica costruttiva delle macchine confezionatrici, generalmente ricomprese nella classificazione internazionale B65b. The present invention refers to the construction technique of packaging machines, generally included in the international classification B65b.
STATO DELLA TECNICA STATE OF THE TECHNIQUE
Sono noti diversi tipi di macchine confezionatrici che, partendo da un rotolo di nastro piano di materiale flessibile, lo avvolgono attorno ad un tubo formatore, termosaldandolo longitudinalmente. Il tubo di materiale flessibile cosi' ottenuto viene poi trasversalmente sigillato per ottenere sacchetti presentanti i lembi trasversali sporgenti che non consentono alla confezione di assumere stabilmente un assetto verticale su un piano di appoggio orizzontale. Different types of packaging machines are known which, starting from a roll of flat ribbon of flexible material, wrap it around a forming tube, heat-sealing it longitudinally. The tube of flexible material thus obtained is then transversely sealed to obtain bags having transversal protruding flaps which do not allow the package to take a stable vertical position on a horizontal support surface.
Il problema da risolvere e' quello di intervenire durante la formazione del sacchetto per piegare il lembo della termosaldatura sporgente dal sacchetto in formazione, per spianarlo e fissarlo alla parete di fondo per termosaldatura o con colla . The problem to be solved is to intervene during the formation of the bag to fold the flap of the heat seal protruding from the bag being formed, to flatten it and fix it to the bottom wall by heat sealing or with glue.

La figura 2 indica l'inizio della fase di termosigillatura trasversale. Figure 1 is a diagram of the phase in which the bag being formed, obtained with the use of a forming tube, has the transversal heat-sealing flap already folded, flattened and blocked on the bottom wall of the package. Figure 2 indicates the start of the transverse heat sealing phase.
La figura 3 indica il completamento della fase di termosigillatura trasversale. Figure 3 indicates the completion of the transverse heat sealing step.

La figura 6 mostra il proseguire dell'intervento del dispositivo ausiliario a contrasto con la parete terminale inferiore del tubo formatore. Figure 6 shows the continuation of the intervention of the auxiliary device in contrast with the lower end wall of the forming tube.
La figura 7 evidenzia che l'intervento del dispositivo ausiliario risvolta il lembo di termosigillatura contro il fondo del sacchetto a contrasto con la parete terminale del tubo formatore. Figure 7 shows that the intervention of the auxiliary device turns the heat-sealing flap against the bottom of the bag in contrast with the end wall of the forming tube.
La figura 8 indica il fissaggio per termosaldatura del lembo al fondo del sacchetto. La figura 9 mostra la fase di ritorno del dispositivo ausiliario. Figure 8 shows the flap to be fixed by heat sealing to the bottom of the bag. Figure 9 shows the return phase of the auxiliary device.
La figura 10 indica l'avanzamento del sacchetto successivo presentante il lembo già' spianato e fissato al fondo. Figure 10 indicates the advancement of the next bag having the flap already flattened and fixed to the bottom.
Le figure 11 e 12 schematizzano una variante del dispositivo con l'impiego di uno spruzzatore di colla per fissare il lembo al fondo del sacchetto. Figures 11 and 12 schematize a variant of the device with the use of a glue sprayer to fix the flap to the bottom of the bag.
Le figure 13 e 14 sono viste prospettiche del dispositivo in oggetto. Figures 13 and 14 are perspective views of the device in question.
Nelle figure delle tavole allegate i singoli particolari sono cosi' contraddistinti: 1 indica un tubo formatore in questo esempio verticale. In the figures of the attached tables the individual details are marked as follows: 1 indicates a forming tube in this vertical example.
2 indica un sacchetto con il lembo risultante dalla termosaldatura trasversale non piu' sporgente dal fondo, ma già' risvoltato durante la formazione del sacchetto e fissato alla parete di fondo per termosaldatura o con colla. 2 indicates a bag with the flap resulting from the transversal heat-sealing no longer protruding from the bottom, but already turned upside down during the formation of the bag and fixed to the bottom wall by heat-sealing or with glue.
3 indica la parete di fondo del sacchetto. 3 indicates the bottom wall of the bag.
4 indica il lembo risultante dalla operazione di termosaldatura trasversale. 4 indicates the flap resulting from the transversal heat sealing operation.

L'evidenza delle figure chiarisce che il dispositivo in oggetto e' applicabile a diversi tipi di macchine confezionatrici a tubo formatore . The evidence of the figures clarifies that the device in question is applicable to different types of forming tube packaging machines.
Si mette in evidenza il fatto che l'operazione di risvoltare il lembo 4 ed il suo fissaggio alla parete di fondo del sacchetto, per termosaldatura o con colla avviene durante il processo di formazione del sacchetto. It is pointed out that the operation of turning up the flap 4 and fixing it to the bottom wall of the bag, by heat sealing or with glue, takes place during the process of forming the bag.
Naturalmente l'invenzione e' suscettibile di numerose varianti di realizzazione pratica per quanto riguarda le scelte tecnologiche e il proporzionamento strutturale delle confezionatrici. Naturally, the invention is susceptible of numerous variations of practical implementation as regards the technological choices and the structural proportioning of the packaging machines.
Rientreranno pertanto nell'ambito della presente invenzione tutti quei dispositivi applicabili a macchine confezionatrici a tubo formatore, per piegare il lembo della termosaldatura trasversale, sporgente dal fondo del sacchetto in formazione, e per fissarlo alla parete di fondo per termosaldatura o con colla, realizzati con le caratteristiche sostanzialmente descritte ed illustrate ed in seguito rivendicate. Therefore, all those devices applicable to forming tube packaging machines, for folding the flap of the transversal heat seal, protruding from the bottom of the bag being formed, and to fix it to the bottom wall by heat sealing or with glue, made with the characteristics substantially described and illustrated and claimed hereinafter.
