Definitions
- the invention relates to a bag according to claim 1 and a bag making method according to claim 10.
- Bags are known which are produced and filled according to the so-called FFS method (FFS Form FiII and Seal). This method is described inter alia in DE 199 204 78.
- FFS method FFS Form FiII and Seal
- a film tube is unwound from an unwinding device and fed to an FFS machine, in which the film tube is first separated into sacks by transverse cutting welds.
- These bags are detected by suitable gripping devices, filled in a filling station, closed by another cross-welding and thus discharged as filled and sealed bags from the machine.
- FFS Form FiII and Seal
- EP 1 600 399 A1 proposes to provide a bag with a ventilation channel, which is formed from two film layers.
- the one film layer has first vents to the bag interior and the other second vents to the atmosphere.
- the object of the present invention is to propose a bag in which the ratio between ventability and possible loss of filling material is improved in the closed state.
- At least one second venting channel is provided which is connected to the first channel through second venting openings and which in turn has third venting openings which vent the at least one second venting channel.
- the direct connections of the first venting channel to the atmosphere can often be saved by this measure, without the ventability of the bag falling below the required level.
- the outer film layer may be provided with a less permeable perforation than the first film layer.
- the vent channel of the bag according to the invention is usually formed by a double film layer parallel to the tube axis of the bag. For this purpose, the double layer can already be formed during tube formation.
- venting channel in the sense of the present Registration, however, is to be understood as meaning any manifestation of sack components which are suitable for guiding air from the interior of the sack to further vents, which may well also lead to a further venting channel. In general, such venting channels will have a greater length than width and be formed of double film layers.
- At least one second venting channel is provided in addition to the at least one first venting channel.
- the ordinal numbers first, second and later third vent channel depend on the order in which the air escaping from the interior of the bag flows through the channels on their way into the atmosphere - that is, the outer space.
- the at least one second venting duct generally has at least areas without direct connections to the interior of the bag. In this way, the connections to the interior of the bag are spaced from the vents to the atmosphere along the bag surface, which increases the tightness. Direct connections to the interior of the bag are preferably either no longer present in the at least one second venting channel or limited to the areas in which the axes of the first and second channels intersect. The same applies to the third and further venting channels in relation to the second.
- a venting channel here is an at least partially delimited space.
- vents should be in the crossing region of the two channels either from the first to the second or from the second to the third channel or to the atmosphere. If there are vents from the first to the second channel in or near the crossing area, it is advantageous to space the openings from the second to the third channel or to the atmosphere thereof.
- the gusset area can be used for this purpose.
- connection openings between the bag interior and the at least first ventilation channel are the first ventilation openings
- the connections between the at least one first ventilation channel to the at least second are the second ventilation openings and so on.
- channels at a sack end so that a wall or boundary of the respective channel is already formed by a final weld
- the other wall may then be formed by a transverse weld
- Such channels may be first, second or even third venting channels.
- the other bag end can be designed in the same way. In general, symmetrical bag designs should be preferred.
- vents come, as already mentioned, interruptions in separating welds in question. Further advantageous vents are holes that can come through punches and perforations to conditions. Often, micro-perforations will be beneficial.
- microperforation is understood to mean above all those perforations whose diameter is smaller than the average or the smallest particle size of the filling material.
- Filter here means all types of felt-like or stoffartigem material - whether "woven” (woven) or “nonwoven” (non-woven) - understood that on the one hand is permeable to air, but on the other hand dust-like solids can stop.
- the production of a bag according to the invention can advantageously be combined with elements of the FFS method in many ways. However, it has been found in experiments to be advantageous that the ventilation ducts extending along the hose axis are already produced during tube formation on a tube former. If then bags with a second are made largely parallel to the first channel extending second vent channel, it is possible to attach the necessary transverse seams on the tube former or on the FFS machine. Since the FFS machine works at least partially intermittently, it is better to form the transverse welds here. This can be done by an advantageous (double) welding tool.

- the first vent passage 20 is formed.
- the outer boundary wall 30 of this channel 20 may have microperforations not shown in the present example.
- the inner boundary wall also inner film layer
- the arrow 70 indicates that air can escape through the aforementioned microperforations.
- the bag interior 210 is used for storage of not shown contents.
- FIG. 2 shows one end of a bag 220 according to the invention. Again, a first vent channel is formed by the longitudinal welds 50 and 60.
- This first channel opens via the vent openings 90 into the second vent channel 140, which is formed by the Endabsch professionung 110 and the additional transverse weld 150.
- the additional Absch availabilityung 150 takes over at the edges of the bag and the function of a Eckabsch spaung 130.
- the present bag is mainly in the gussets 80 through the needling 120, which is far away from the crossing region between the first 20 and second channel 140, against the Atmosphere vented.
- the two channels are connected by the vents 90 and 100 together. These are due to the interruption of the welds 50 and 150 come about. Such interruptions can be achieved by appropriately shaped or controlled welding tools and / or a corresponding coating of the film components, which just should not be welded.
- FIG. 3 shows the section AA from FIG. 2 from the viewing direction indicated by the arrows 160, with elements behind the cutting plane could not be presented for illustrative reasons.
- the effect of the interruption of the weld 50 is shown again in more detail.
- the air flows along the arrow 170 from the overlapping region of the boundary walls 30 and 40 into the second venting channel 140. Along the arrows 170 and 180, the air then passes to the third vents 120, then exits along the arrows 190 into the atmosphere.
- FIG. 4 shows a sack end, in which only the vent openings are designed differently than in the exemplary embodiment illustrated in FIGS. 2 and 3, in which the connection between the first 20 and the second vent channel 140 is interrupted 90 of the welds 150, which can also be referred to as second vent openings and 50 is formed.
- the weld 150 which extend the first vent passage 20 into the area above the second vent passage 140.
- the sheet material in this overlap area between the two vent channels 20 and 140 is perforated by the openings 200 so that the channel 20 is vented through these openings 200 and the interruptions 90 of the weld in the second channel 140 (see also Fig. 7).
- the final venting of the second channel 140 to atmosphere is again through the needling 120.
- FIG. 5 shows the section DD of Figure 5, which only shows that the second vent channel 140 between the top seam 11 and the other transverse weld seam 15 is arranged.
- FIG. 6 shows the section BB from FIG. 4, which shows the overlap region between the two venting channels 20 and 140.
- the openings 200 could again be indicated only by arrow and reference numerals.
- the reference numeral 210 the bag interior is provided.
- the interruptions of the weld 150 are indicated again. Objects behind the cutting plane were not shown.
- FIG. 7 shows the section CC from FIG. 4, in which the arrows 260 symbolize the air flows in the second venting channel 140, which come about through the air flow through the openings 200 introduced into the inner boundary wall 40 but not illustrated here.
- the Arrows 250 symbolize the flow of air from the outlet openings 120 to the atmosphere.
- vents in the context of the present document, ie vents that connect the bag interior 210 and the first vent channel 20 with each other, are not shown in the figures for illustrative reasons. Likewise, it has been omitted to represent a likewise advantageous needling, perforation or micro perforation of the outer boundary wall 30 of the first venting channel.
- FIG. 8 shows a further embodiment of a bag 29 according to the invention, in which two largely parallel venting channels 20 and 21 are provided, which are delimited by the longitudinal seams 26, 27 and 28.
- the first vent channel 20 communicates with the interior of the bag via the first vent openings 22 and in turn is vented via the indicated by the rectangle 23 second vent openings 23 in the second vent passage 21.
- This 21 has vents 24 to the atmosphere.
- the bag 29 is formed from a piece of hose and closed by Endabsch spasch spas 22.
- sacks As is customary in sacks, it is preferably stacked on its surface formed by the bag width x and the bag length z (along the tube axis.) When this occurs, a height offset occurs between the first and third vent openings 22 and 24 and the second vent openings 23.
- FIGS. 9 to 14 show devices for forming hoses or assemblies of these devices. These devices are advantageously suitable for the production of hoses, which may be the starting point for the production of bags according to the invention.
- Packaging means are advantageously produced by a folding process from a flat web with subsequent application of a longitudinal seam in the overlapping region. To be in this packaging z.
- This venting can be done by a labyrinth vent.
- This labyrinth vent is overlapped by two seams is welded, generated.
- openings provide access to the interior of the packaging. The air can then penetrate into this area and penetrate as known through, for example, openings in the enclosing welds to the outside.
- Also known are openings in the outer layer, which allows offset in height to the opening in the inner layer, an outflow of air.
- both options have in common that the path between the first opening and the second opening can amount to a maximum of one bag length. It is therefore advantageous to increase this way by measures and to make it difficult to penetrate water or getting out of packaged goods.
- the apparatus 102 For the manufacture of a package as described above, the apparatus 102 described below may be used.
- the device is shown in FIGS. 9 and 10 and constructed as follows.
- a flat 10 of z. B. plastic handled From a settlement 1 is a flat 10 of z. B. plastic handled.
- This flat track is guided over deflecting rollers 2 on a deflection device 3.
- This deflection consists of an air turning bar, which is mounted 45 ° to the direction of unwinding.
- the air turning bar is also provided with a device which makes it possible to move the air turning bar in the machine direction or transversely thereto. As a result, a side edge control is effected and the incoming web is always performed even when eg not straight line rollers always constant in the device.
- the web runs transversely to the machine direction and is fed via further deflecting rollers 2 to a device 11 which forms a first gusset 12.
- This gusset formation is constructed in accordance with FIG.
- the film with inserted first side fold is fed by a driven feed roller 4 to a further device 103 which comprises conical tools 5.
- These tools are also equipped with the possibility of reducing friction by releasing air. With the help of these tools, the film web is folded into a tube. As shown in FIG. 12, the second side fold of the gusseted tube is formed at the pointed ends of the conical tools. It is advantageous if the geometric condition L1 ⁇ L2 holds.
- the cones are designed to produce different side fold depths, displaceable along its axis of rotation.
- This device can, for. B. a Leksnahtextruder 14, which is shown with the exit region in Fig. 13.
- an extrudate is conveyed from at least one opening 15 to the location where the overlap area has been formed so as to be closed after the tube has passed the deflecting rollers 2.
- the just applied extrudate is cooled by means of a seam cooling roll 7 and the tube is welded.
- the finished hose 35 is controlled in a control section 18 by a measuring device 18.
- This measuring device 19 determines z. B. with an infrared camera, the temperature of the longitudinal seam 26, 27, 28. In the case of excessive deviation from previously determined temperatures can be assumed that a faulty longitudinal seam. In such a case, an error is reported and the system is switched off.
- a following cooling section 36 effects a cooling of the seam to room temperature and allows a subsequent winding with a corresponding winder 9. It has been found to be advantageous to guide the gusseted hose each before larger deflections on so-called crushing rollers 8.
- a third seam is introduced as a web in addition to the known two longitudinal seams.
- This web is used for the separation between the channel in the vented from the packaging material through the inner layer and the channel is vented to the outside.
- This bar is left open at a suitable location and thus creates a channel length that extends to twice the bag length.
- the situation for creating the three seams is shown in FIG. To mention here are the extruded from the extruder 14 through the extrusion die 15 melt strands 34. In this illustration, the presentation of film 10 was omitted.
- FIG. 16 A sack with only one vent passage 20 which vents the bag interior via the first vent openings 22 and delivers the air to the atmosphere via the second vent openings 23 configured as discontinuities of the seams 26, 28 is shown in FIG.
- this bag can be made according to a method or apparatus shown here.
- two venting channels 20 and 21 are present.
- the various groups of vents 22, 23 and 24 again have the usual function.
- Figure 17 a bag according to the invention is shown, wherein the reference numerals have the usual function. In FIG. 18, above all, the position and the adjustability of the additional guide roller 37 are shown.
- rollers 37 can be adjusted in the transport direction of the film - shown here by the arrow C. They - in the figure exist two such rollers 37 but can also be against the running foil - be made in the direction of arrow B.
- An additional positive adjustment option is their pivotability about the axis D. This axis runs largely parallel to the film transport direction. The rollers 37 and their adjustment have proven in tests to be positive for the prevention of wrinkles in the film tube.
- the middle seam that creates the web can be interrupted by applying a paint on the incoming web.
