Definitions
- the invention relates to a gusseted bag according to the preamble of claim 1, a method for producing and filling such a gusseted bag and a corresponding FFS machine.
- the generic filling of sacks is carried out using a wide variety of devices.
- the sack to be filled is often gripped by a plurality of pairs of gripper tongs during the filling process.
- FFS Form Fill and Seal
- a special feature of the way these machines work is the sealing of the bags after the filling process.
- Such a device is known, inter alia, from DE 199 36 660 A1.
- a tube section made of thermoplastic plastic with a bottom weld seam is filled with filling material in a filling station.
- the bags produced by FFS machines are often filled with free-flowing goods. For this reason, too, these sacks are usually not provided with any holes or incisions.
- a first exception are ventilation openings, which are usually made in a large part of the outer surface of the bag. These openings are designed so that their diameter is no more than one mm in order to prevent the contents from trickling out. So-called micro-perforations have been developed for particularly fine filling goods, which have ventilation holes with diameters that are smaller than 0.2 mm.
- tear-open perforation is understood to mean a perforation made of incisions or punchings.
- a tear perforation serves to simplify the tearing of the bag cover.
- a tearing open of the bag cover in the sense of this publication can also be torn off with parts of the
- Perforation device assigned to the machine is perforated before the hoses are rewound and this hose reel is fed to the FFS machine.
- tear perforation in particular forms a weak point through which the filling material trickles.
- the object of the present invention is therefore to provide a flat or gusseted bag 30, - which was manufactured and filled by an FFS machine and - which is easy to tear open and - which is characterized by lower trickle losses.
- the present invention is based on the side gusset sacks described and produced and filled in the FFS process and achieves this object in that the sack has a corner weld in the area of at least one corner.
- the measure according to the invention is - as can be gathered from claim 1 - in the same way for flat sacks.
- FIG. 1 A sack according to the invention
- FIG. 2 A sack according to the prior art Fig. 3 Another embodiment of sacks according to the invention Fig. 4 Another embodiment of sacks according to the invention Fig. 5 Another embodiment of sacks according to the invention Fig. 6 Another embodiment of sacks according to the invention Fig. 7 A separation cut, welding and perforation station in a passive state.
- Fig. 8 The same separating, welding and perforation station as in Fig. 7 during cutting, welding and perforating.
- Fig. 9 An illustration of a film tube section.
- Fig. 10 A sketch of an incision tool
- FIG. 2 shows a gusseted bag 201 according to the prior art, in which the gussets are indicated by the dashed lines 203.
- a bottom seam 205 closes the bottom end 210 and a top seam 204 closes the ends of the sack at the top end 211.
- the sack has a tear perforation with perforation incisions 207.
- 1 shows an already very advanced example of a sack 200 according to the invention, which is provided with corner welds 206. It should also be noted that the tear-off perforation breaks down into a tear-off perforation with longer perforation incisions 207 and a tear-off perforation with shorter perforation incisions 208.
- the longer perforation incisions 207 are located in the area between the edge of the bag 209 and the corner weld 206, while the shorter incisions 208 are located in the area between the center line M of the bag 200 and the corner weld 206 of the corner, which is subjected to the tear-off perforation, are located.
- the sack 200 is upside down relative to the sack 201, that is to say that the foot end of the sack 210 is in the upper region of FIG. 1, while the head end is in the lower region.
- the tear-off perforation 207, 208 is thus located in the region of the foot end of this sack, which has advantages in the filling process to be described.
- FIG. 3 again shows the foot section 210 of the sack 200 already shown in FIG. 1 with the properties already described.
- FIG. 4 shows another exemplary embodiment 212 of a sack according to the invention with the corner welds 206 according to the invention.
- the sack 212 has only one notch or one notch 213.
- this single incision is also considered a tear-off perforation in the sense of the present publication.
- passages (labyrinth ventilation) 229 can be introduced for better ventilation of the sack. It is expedient if these passages 229 also do not allow any filler material to pass through.
- the tear-off perforation of the sack 214 shown in FIG. 5 is designed differently. Similar to the tear-off perforation of the sack 200, it is composed of a tear-off perforation 207 with long incisions and a perforation 208 with shorter incisions. However, this tear-off perforation is further provided with a perforation 215, which is a tear-off Part of the weld seam 208, which closes the foot end 210 of the sack 214, is permitted. This makes it easier to tear off this part.
- FIG. 6 A last exemplary embodiment of a sack 217 according to the invention is shown in FIG. 6. Similar to the embodiment with the bag 200, a perforation with long perforation incisions 207 is present in the area between the edge 209 of the bag 217 and the corner weld 206. However, this applies to both corners of the foot region 210 of the sack shown in FIG. Between the two corner welds 206 of the bag 217 there is a further perforation 216, which is formed by shorter perforation incisions.
- FIGS. 7 and 8 Components of an FFS machine are shown in FIGS. 7 and 8. The location of these components can be seen, inter alia, from the figures in German application 102 17 397.4, which has not yet been published.
- the machine components shown are a cut-off and welding station 230 and a needle station 240. However, the components normally provided for needling and for venting the sack are used for perforation.
- the cut and weld station 230 is located in an FFS machine in the front of the processing cycle.
- the film tube 219 is unwound from an unwinding and fed into the separating and welding station via feed rollers 218.
- FIGS. 7 and 8 Components of an FFS machine are shown in FIGS.
- the illustration of the separating cut and welding station 230 begins with the pair of feed rollers, which is formed from the feed rollers 218.
- the film tube 219 runs through the nip formed by these two preferred rollers 218 into the separating, welding and perforation station 230.
- the perforation station 220 consists in detail of the holder of the knife carrier 221, to which the knife carrier 223, which is movable in the x direction, is articulated.
- the knife carrier 223 carries the knife 228 and the squeeze rubber 224.
- the knife 228 travels through the stripper 226 or through a recess of the stripper 226, which is not shown, into the Knife receiving channel 227, the counterpart of the knife 225.
- the counterpart of the knife 225 is formed by a traverse.
- the first perforation station 220 is followed by the separating cut station 230, which again consists of the holder of the knife carrier 231, the knife carrier 233, the knife 226, the welding bar 234, the counter support 235, the knife receiving channel 236 and the knife 238.
- the incision movement of the knife 238 takes place analogously to the incision movement at the first perforation station 220, which can also be seen from FIG. 8.
- FIG. 8 shows the first perforation station 220, the separating and welding station 230 and the second possible needle station 240 in the state in which they cut into the film web and cut or perforate the film tube web.
- the already mentioned second needle station 240 is constructed analogously to the first perforation station 220.
- the numbering of the functional elements 241-248 of the second needle station 240 takes place analogously to the numbering of the functional elements 221-228 of the first perforation station 220.
- the first or the second perforation station can be used for needling while the other station is perforating.
- FIG. 9 shows that section 250 of a film tube into which the separating cut 256 is made and thus divides two sacks.
- the sack that is created later is of the same type as the sack 200 shown in FIGS. 1 and 3.
- the foot end 210 of this sack can be seen.
- the sack is provided with a transverse weld 258, which forms the bottom. Large perforation incisions 207 and shorter perforation incisions 208 are again located in the area of one of the corners of the sack.
- needles 251 are shown in FIG. 9, which indicate, by way of example, that the sack can also be needled.
- Corner welds 206 are also shown in FIG.
- the sack section shown in this form does not necessarily have to be present in this form during the manufacture of the sack. Rather, it may be, for example, that the corner welds 206 and the bottom seams 205 can be added to the bag 200 before it is separated from the film tube 219.
- the purpose of FIG. 9 is therefore primarily to illustrate the position of the various features of the bag 200.
- FIG. 10 shows a perforation tool 259, which consists of the perforation knives 253 and 252, which are attached to the knife carrier 254. These perforation knives cut into the tube section 250.
- This section of a film tube 250 which is also shown in FIG. 9, contains four-layer film material 257 and two-layer film material
- the four-layer film material 257 is located in the area of the gussets, while the two-layer material 260 is found in the middle area of the sack.
- the arrows z and y illustrate the respective position of the bag components.
- z again corresponds to the transport direction of the film tube, while y
- FIG. 15 extends in the direction of the width of the film tube or the sacks.
- the two FIGS. 9 and 10 are aligned in the direction y, the right part of the film tube section 250 not being shown in FIG. 10.
- FIG. 10 also illustrates that the knives 253 cut further into the hose section 250 than the knives 252, so that the
