Definitions
- the invention initially relates to a method for the simultaneous production of two bags each, in particular vending machine bags from successive ones Cross cutting and cross cutting formed double film web sections one flat-lay tubular film web made of thermoplastic plastic as well as for packets Stack the bags, the double film web sections being separated by a Direction of movement of the tubular film web extending longitudinal cut in two beforehand bags provided with receiving holes are divided by a Transfer device detected and on the spacing of the receiving holes next to each other arranged pins of a stacked moving pin stack conveyor be filed.
- a method and a device for its implementation is in US 5,085,111.
- EP 0701895-A describes a machine and a method for producing Plastic bags are known in which the position of a cross cutting device along Direction of movement of the film web is adjusted.
- a detector near the cross cutter recognizes the contour of recesses in the film web and controls it depending on the position of the cutting device.
- the invention has for its object a method for the simultaneous production of two bags each, in particular vending machine bags, made of double film web sections to propose a flat tubular film sheet made of thermoplastic material, by the manufacturing and / or setting inaccuracies of the facilities for Manufacture of the bags and / or stack of bags related disadvantages, which affect the precise location Positioning the bags and thus affect their precise stacking, so quickly be compensated for as much as possible by means of a particularly simple device trained funds.
- this problem is solved in that the Tubular film web and the devices for producing the bags and / or the Bag stacks are automatically controlled relative to each other, the control with the exception of the unwinding area of the tubular film web, that the Tubular film web is guided correctly and the facilities for producing the Bags and / or the stack of bags with respect to a predetermined longitudinal end Marking of the tubular film web driven and opposite the tubular film web are automatically adjusted transversely to their direction of travel.
- the Tubular film web when the position changes, the Tubular film web no longer adjusts it itself, but rather the bag-forming one controlled or stacking facilities themselves.
- This machine control and Adjustment can be carried out much faster and more accurately than a modulation and adjustment of the tubular film web, especially if it is with comparatively high web speed is moved.
- This simple and in particular quick adjustment of the facilities can be the usual Avoid material loss of the tubular film web and at the same time is the exact positioning for example of receiving holes in automatic bags compared to the Longitudinal cutting edge guaranteed in an optimal manner, so that the handling of Vending machine bags, for example in packaging machines, e.g. B. bread or bread slices pack, is also improved.
- the specified marking on the tubular film web can be done in different ways and Can be achieved, for example, in that a serving as a tax mark longitudinal marking line applied to the tubular film web, preferably is printed on. This print can either already be made during the extrusion of the Tubular film web or during its subsequent assembly, i.e. when editing for Formation of bags can be applied.
- Another option is to do without a line print entirely, rather one of the two edges or both edges of the tubular film web than to use the specified marking.
- this can be done in terms of the device, for example achieve that the modulation via a scanning device in the form of a scanning head, for example in the area of a bottom folding device, a punching device, a slitter and optionally a strip cutter is made, that is, in all known devices that are used for the production of bags, especially vending machine bags, are necessary.
- a bag making machine 1 is shown schematically, for simultaneous Manufacture of two bags, so-called automatic bags, trained and is set up.
- An unwind stand 2 with a winding roll 3 is part of the machine a tubular film web 4 made of thermoplastic material.
- the tubular film web 4 is within a processing state 5 indicated only schematically above housed drive rollers and tensioning rollers, not shown.
- a marking line printing unit 6 is arranged, on which the Tubular film web 4 is passed and its function explained in more detail below becomes.
- the processing stand 5 also takes a side or bottom folding insertion device 7 (see FIG. 2) and a strip cutting device 8 (see FIG. 3), the Meaning is explained in more detail below.
- FIG. 4 Behind the processing stand 5 is one Hole punching device 9 arranged (see FIG. 4), the function of which is also shown below is described in more detail.
- the hole punching device 9 is followed by a cross welding separating device 11 (see FIG. 5) and a transfer device 12, to which a Stacking device 13 with a pin stack conveyor 14 connects. In the area the latter is finally arranged a longitudinal cutting device 15 (see FIG. 7).
- the bottom gusset insertion device 7 shown in FIG. 2 has in a manner known per se Side swords 16, through the formation of an air bubble inside the tubular film Side folds 17, which represent a bottom fold in the finished bag, into the Tubular film web 4 can be introduced.
- the side swords 16 are one Not shown device transverse to the direction of movement of the tubular film web 4th adjustable. The training is such that during the run the tubular film web 4 as a function of one described in more detail below Marking an automatic control and adjustment takes place.
- the tubular film web is in the area of the strip cutting device 8 shown in FIG 4 guided over a deflection roller 21.
- the strip cutting device 8 has one Support rod 22, which is arranged in the left part of the processing station 5.
- Support block 23 is adjustably fixed on the support rod 22.
- the support block 23 supports Spacing-arranged cutting knives 24 which are arranged such that they separate a strip 25 from the top of the tubular film web 4, so that in a gap 26 is formed in the upper web. This way you can use a border create provided bags, d. H. in such bags used as vending machine bags the marginal edges delimiting the bag openings are not at the same height.
- the hole punching device 9 shown in FIG. 4 has two adjustment drives 27, via the perforated tools 29 seated on support plates 28 can be actuated, with the aid of which Area of the gap 26 in each case two adjacent bore holes 31 in the tubular film web 4 can be introduced, the meaning below is explained in more detail.
- Cross cut welding device 11 has a lower welding roller 32 and an upper one Welding bar 33, which is movable substantially in the vertical plane.
- the longitudinal cutting device 15 With the help of the longitudinal cutting device 15 shown in Figure 7, the on both sides of the Pin stack conveyor 13 depending double film web section 35 in two Cut the bag packs lengthways, as shown in Figure 8. To this end the longitudinal cutting device 15 has two drive units 41 with a cutting bar 42, a cutting knife 43 attached to it, which is essentially in vertical direction can be moved up and down. The two themselves through the Longitudinal cut bag packs are shown in Figures 8 and 9 with 35 a and 35 b referred to.
- the cutting knife is used to connect or block the individual bags in packages 43 brought to a certain temperature so that when penetrating of the cutting knife the superimposed edges of each bag stack welded together or fused.
- Figures 10 and 11 are two different configurations of bags shown, which is generated by the method and the device according to the invention can be.
- Figure 10 illustrates with an edge or a lip provided machine bags, in which the upper, defining the bag opening Edges are not at the same level, as seen from the removal of strip 25 Figure 3 and the resulting gap 26 results.
- FIG. 11 illustrates the configuration of a double film web section according to perforations 44 have been created by means of a perforator (not shown). After the double film web sections along the line A into two individual bags have been separated, the edges of the bags are level because of the perforation line 44 is formed in both surfaces.
- FIGS. 14 and 15 show a spreading device 18 which is in the region of the Pin stack conveyor 14 is arranged and about a common pivot axis 19 has pivotable spreading arms 20.
- the spreading of the packs of bags is necessary to pack the bags on, not shown, substantially U-shaped trained wire brackets.
- the wire brackets are hand made from below introduced what was previously not possible on two-track machines.
- Figure 12 is shown in a schematic representation, as with the aid of a scanning device 45 and a marking line 46 on the tubular film web 4 a desired relative Alignment of the bag-forming facilities, in particular with regard to the bottom fold insertion device 7, the strip cutting device 8 and the punching device 9 is made opposite the tubular film web 4. According to that in FIG. 12 The process sequence shown is first on the underside of the tubular film web 4 with the help of the marking line printing unit 6, the marking line 46 on the underside of the Tubular film web 4 applied (see FIG. 12 a).
- a probe 47 for example one works Photocell of the scanner 45 together, in such a way that at one Deflection the associated device, so for example the bottom folding insertion device 7 is controlled accordingly.
