Definitions

  • the present invention essentially relates to a process for the automatic packaging of any products, such as for example foodstuffs, in flexible bags.
  • the present invention aims to solve the above problems by providing a method and an automatic machine for packaging products in bags, which allow automatic and perfect positioning of the bags, particularly at the level from the heat-sealing station, as well as easy and automatic recovery of cut bag scraps.
  • the invention achieves an automatic packaging process for any products, such as for example foodstuffs, in a chain of flexible bags joined together, this process essentially consisting in passing the bags successively to a post of filling and at a sealed bag closing station, and being characterized in that the bags are joined by at least one flexible link which extends in the vicinity of and substantially parallel to the opening of the bags, and in that with the flexible link, pulling is carried out on the bags before heat-sealing in the closure station so as to make the edges of the opening of the previously filled bags perfectly flat and parallel to facilitate their sealed closure along a welding line which is slightly in removal of the link, and after the bags have been sealed, a cut is made between the welding line and the link, then p ar winding the falls previously cut and all connected by the link.
  • the present invention also relates to a machine for implementing the method meeting the above characteristics, this machine comprising a station for filling bags joined by a link and a station for sealing these bags, said machine being characterized by Features of claim 2.
  • the tensioning means can be constituted by one or more rollers or by one or more tension arms.
  • Figure 1 is a very schematic view in elevation of an automatic packaging machine for flexible bags according to this invention.
  • FIG. 2 is a schematic plan view from above of the machine shown in FIG. 1.
  • a machine according to this invention allows the packaging of plastic bags S in particular, these bags all being joined by a flexible link 1 such as a band fixed by any suitable means in the vicinity of the opening O of the bags and substantially parallel to this opening, as can be seen in FIG. 2.
  • a flexible link 1 such as a band fixed by any suitable means in the vicinity of the opening O of the bags and substantially parallel to this opening, as can be seen in FIG. 2.
  • R a station for filling these bags
  • 2 a station for sealing the bags after they have been filled .
  • This closing station 2 essentially comprises an enclosure 3 which is generally connected to a vacuum source (not shown) and which contains heated elements or bars 4, in a variable number, actuated vertically by any appropriate means (not shown), and between which the S bags must pass after filling in order to be heat sealed.
  • a knife is provided schematically identified at 5, and beyond this knife is provided a drum 6 allowing the recovery of the cut bag falls, as will be explained in detail further on how it works.
  • a drum 6 any other recovery system, such as a suction system for example, could be used without departing from the scope of the invention.
  • a means of transport such as for example a conveyor 7 ensuring the evacuation of the filled and heat-sealed bags S and which must for example undergo heat shrinkage.
  • Means such as for example rollers 8, or equivalent means, are provided at the inlet and / or at the outlet of the enclosure 3 to exert tension on the link or ribbon 1 connecting the bags S in order to ensure the perfect parallel superposition of the edges of the opening O of the bags when these are between the elements 4 of the press ensuring the heat sealing.
  • the bags connected to each other may be in the form of a roll supplying the loading station R.
  • the bags S are not tensioned by the ribbon or link 1 so as to allow the bags to open and consequently the loading of products to be packaged, as shown by the arrows F in FIG. 2.
  • line or lines of bags S can rest on, for example, an endless belt or belt conveyor (not shown).
  • the bags S are transferred to the vacuum enclosure 2. But it is important to observe here that traction is exerted on the link or ribbon 1 so as to make the edges of the opening O of the bags S to facilitate their watertight closing by welding of said edges which will be flattened and parallel due to the traction carried out on the link 1 by the rollers 8 or any other suitable means.
  • the knife 5 cuts between the welding line 10 and the link or ribbon 1, while at the outlet of the enclosure 3, the scraps 12 cut by the knife 5 and all connected by the ribbon 1 are automatically wrapped around the drum 6.
  • the bags S filled with a product P under vacuum they are conveyed, as seen in 13, by the conveyor 7 to for example a station ensuring the heat shrinkage of the bags to finally give a product illustrated schematically in 14 in figure 2.
  • An automatic packaging method and machine have therefore been produced according to the invention allowing, thanks to the link connecting the bags, to obtain correct and automatic positioning of these bags during the various packaging operations, and making it possible to eliminate manual interventions and guarantee a tight and clean closure of the bags to finally give the packaged products a beautiful appearance.
  • the means of tensioning the link connecting the bags and providing the flattening of their opening can be other than rollers and, in the case of rollers, can be driven, for example at different speeds, to the using any training source.
  • the material of the link or ribbon and its attachment to the bags can be any.

  1. Verfahren zum selbsttätigen Verpacken von irgendwelchen Erzeugnissen, wie z.B. Nahrungsmitteln in ein laufendes Fliessband von miteinander vereinigten nachgiebigen Beuteln, wobei dieses Verfahren im wesentlichen darin besteht, die Beutel aufeinanderfolgend zu einer Füllstation und zu einer Station für das dichte Verschliessen der Beutel zu befördern und es dadurch gekennzeichnet ist, dass man die Beutel durch wenigstens ein biegsames Verbindungsglied, das sich bis in den Bereich der Öffnung der Beutel und etwa parallel zu dieser erstreckt und dass man mit dem Verbindungsglied einen Zug auf die Beutel vor dem Heisssiegeln in der Verschlußstation ausübt, um die Ränder der Öffnung der vorher gefüllten Beutel vollkommen abzuflachen und parallel zu machen, um deren dichtes Verschliessen entlang einer Schweisslinie, die von dem Verbindungsglied leicht zurückgesetzt ist, zu erleichtern und nach dem dichten Verschliessen der Beutel man einen Schnitt zwischen der Schweisslinie und dem Verbindungsglied durchführt und man dann die vorher abgeschnittenen und alle durch das Verbindungsglied verbundenen Abfälle durch Aufwickeln rückgewinnt.
