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 welding and cross cutting formed double film web sections one flattened tubular film web made of thermoplastic material and stacking the bags in packages, the double film web sections being separated by one longitudinal cut in two in the direction of movement of the tubular film web loot previously 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 are placed in a stack and the tubular film web and the prey devices or elements forming bag stack automatically relative to one another be controlled.
- the invention has for its object a method for simultaneous production of two bags each, in particular vending machine bags, made of double film web sections a flattened tubular film made of thermoplastic to propose through the manufacturing and / or setting inaccuracies of the bag-forming devices or elements-related disadvantages that affect the precise positioning of the bags and thus their precise stacking impact, be compensated for as quickly as possible by means of the device particularly simply trained means.
- this problem is solved in that, with the exception of Unwinding area of the tubular film web the necessary modulation takes place that the tubular film web is guided correctly and the devices or Bag forming elements with respect to a predetermined marking of the tubular film web can be controlled and automatically adjusted relative to the tubular film web.
- the specified marking on the tubular film web can be done in different ways and Can be achieved, for example, that one as a tax mark serving longitudinal marking line applied to the tubular film web, is preferably printed. This imprint can either already at the Extrusion of the tubular film web or during its subsequent assembly, d. H. at processing to form bags.
- Another option is to completely dispense with line printing, 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, if necessary, 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 is known per se Has side swords 16, through which after the formation of an air bubble inside the Tubular film gussets 17, which represent a bottom fold in the finished prey, in the Tubular film web 4 can be introduced.
- the side swords 16 are over a device, not shown, transversely to the direction of movement of the tubular film web 4 adjustable.
- the training is such that during the Runs of the tubular film web 4 depending on 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.
- a Support block 23 is adjustably fixed on the support rod 22.
- the support block 23 supports Distance from each other cutting blades 24 which are arranged such that they cut out a strip 25 from the top of the tubular film web 4 so that 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 two adjacent receiving bores 31 in each 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 essentially movable 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 of them through 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 the penetration 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, the bag opening defining 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 area 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 trained wire bracket.
- 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 tubular film web 4 with respect to the bag-forming devices, in particular with regard to the bottom fold insertion device 7, the strip cutting device 8 and the punching device 9 is made.
- 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.
- non-contact scanning head 47 each through a transmission line 49, and with the interposition of known control and amplifier units 51 with the Adjustment device connected.
- a motor 52 of an actuator 53 and the necessary devices between probe 47 (sensor) and the servomotor 52 are directed according to the respective requirement.
- the other devices are adjusted individually. An adjustment is made according to FIG. 12 c when cutting a strip 26 through the strip cutting device 8 and / or in the case of FIG. 12 d when the receiving bores 31 are drilled in Area of the gap 26 in the area of the punching device 9.
