Description

Apparatus and method for producing strands of flexible material

Technical Field

The present invention relates to an arrangement for producing strands of flexible material according to the preamble of claim 1 and a method for producing strands of flexible material according to the preamble of claim 14.

Background

Strands of flexible material, particularly hoses filled with bulk material or liquid, are used in a variety of ways. For example, they may be used as hose barriers to prevent high water levels, floods and erosion. Furthermore, they can serve as the base of dams and dams, in which case the hose is closed with soil, tarpaulins and similar building materials. This can also be used to build protective military walls or to design landscapes in a targeted manner.

Such flexible material strands (rather than filled bags known primarily from the flood control field) have the advantage that fewer predetermined breaking points can be allowed for flood penetration due to the much greater length of the material strands compared to relatively smaller bags. Furthermore, almost any profile can be produced with such a material strand, since the material strand can be bent relatively freely with respect to the length of the material strand.

Against this background, it is known from DE 10 2004 009 662 A1 that sand is collected in a loader bucket and filled into the collected hose via a conveyor screw connected to the loader bucket. The tube thus filled then forms strands of material that are immediately put in place. However, this only allows for free handling of strands of material having a relatively small diameter and a short length. This is because for larger diameters and associated higher weights, the output into the hose must be at substantially ground level, otherwise the hose will automatically pull out due to its high dead weight. However, in this case placed at the ground level, the device cannot be built with material strands as desired, since the wheel loader cannot be maneuvered as desired, in particular the wheel loader must have a strong base in the place of placement. Further, the length is automatically limited by the push-in hose and cannot be provided in any length.

Disclosure of Invention

It is therefore an object of the present invention to provide an option for producing strands of flexible material which avoids the disadvantages of the prior art. In a preferred aspect of the invention, the material strands can in principle be produced endless. In another preferred aspect, free handling of the material strand is possible even in the case of large diameter material strands. In another preferred aspect of the invention, the production may be carried out in an adjustable manner with respect to the size of the material strands. In another preferred aspect of the invention, the strands of material may be laid down immediately after production.

This object is achieved by the device according to the invention according to claim 1 and the method according to the invention according to claim 14. Advantageous further embodiments are indicated in the dependent claims and in the following description in conjunction with the accompanying drawings.

To the inventors' knowledge, if the apparatus has equipment for producing flexible material strands, equipment for transporting flexible material strands and equipment for dispensing flexible material strands, this object can be achieved in a very simple manner, since the material strands can be produced, transported and dispensed or laid in a single operation, resulting in special economic benefits and suitability which can be adapted as required to suit external conditions.

In an advantageous further embodiment, provision is made for the apparatus for transporting the flexible material strand to have means for feeding the material strand material, means for joining two opposite sides of the material strand material into a tube, and means for filling the material into the produced hose, wherein the means for joining is preferably adjusted to join the two opposite sides by means of at least one stitched seam. The hose is thus particularly easy to produce and can in principle be produced endlessly, since it is always possible to arrange further material strands continuously at the ends of the material strands just used, in order to continue the production on a continuous basis. For this purpose, it is only necessary to interrupt the filling of the material and the advance of the hose.

In an advantageous further embodiment, provision is made for there to be means for winding which stabilize the tube filled with material with a winding, wherein the means for winding compriseA machine. Thus, the strands of material remain highly stable.

In an advantageous further embodiment, it is provided that there is a hose rack, which is preferably provided with a vibrator, in particular an eccentric vibrator. Thus, the material in the material strand may be compacted.

In an advantageous further embodiment, it is provided that the hose rack engages under a first element mounted upstream and used for guiding the hose, forming a gap. In this way, the hose is prevented from getting stuck in the area between the hose shelf and the first element for guiding the hose, thereby ensuring a reliable hose delivery without damaging the hose. The first element for guiding the hose may comprise a guiding tube, for example, used within the framework of the hose production and filling process.

In an advantageous further embodiment, it is provided that the hose rack engages in a second element mounted downstream and used for guiding the hose, forms a gap, or engages over the second element mounted downstream. Thus, it is ensured that the advance of the hose is not damaged by jamming, while the hose can be wound in the area between the hose shelf and the second element for guiding the hose. In this case, the gap ensures removal of the windings. If the portion of the hose shelf which is optionally engaged in the second element or above the second element is designed as one or more fingers and/or as a shell element and in particular is designed to be resilient, the pulling out is particularly simple and safe, since the hose can easily slide on the second element, wherein the shell element can also be combined with one or more fingers. The second element for guiding the hose may be, for example, a receiving tube for the strands of finished material. If it comprises a tube, the hose rack is engaged therein, and if it comprises a shell or similar element that is open from the top, the hose rack is engaged above it.

In a further advantageous embodiment, it is provided that there is a filling level sensor, preferably in the form of a wheel hinged on a lever or another suitable sensor, by means of which the filling level in the flexible material can be determined, wherein the device is in particular adjusted to control the means for filling material, the means for joining, the means for winding and/or the means for pulling out the strands of material such that a predetermined filling level is maintained, wherein preferably a tolerance range around the predetermined filling level is provided. Therefore, an optimal production with stable quality can always be achieved.

In an advantageous further embodiment, provision is made that strand guiding means are present, which transport the material strands and have a support for the material strands, wherein the strand guiding means preferably have means for weighting the material strands relative to the support. The transport of the strands of material within the device is therefore particularly easy.

In a further advantageous embodiment, provision is made for the means for weighting to be designed to be able to be pressed against the support, wherein preferably at least one actuator is present, which is designed in particular as an electric motor, a hydraulic motor or a pneumatic motor. The transport of the strands of material within the device is thus particularly safe.

In a further advantageous embodiment, the strand guide has a drive for the strand of material, wherein the drive is preferably designed as one or more rollers and/or one or more belts. The transport of the strands of material within the device is therefore particularly easy.

In an advantageous further embodiment, provision is made for the strand guiding device to have means for laterally guiding the strands of material. The transport of the strands of material within the device is thus particularly safe. The means for laterally guiding the strands of material may also preferably be designed as one or more rollers and/or one or more belts.

In an advantageous further embodiment, it is provided that in the case of two continuous belts, in the conveying region between the belts, the belt end of the belt arranged upstream is arranged vertically higher than the belt start of the belt arranged downstream, wherein at least one belt preferably runs in an ascending manner with respect to the conveying direction. Thus, clogging of the strands of material and damage of the hose between the two belts is effectively prevented. This is particularly advantageous for the drive means. In this case, "belt end" or "belt start" means the respective deflection point of the endless belt as appropriate.

In an advantageous further embodiment, it is therefore also provided that, in the case of two continuous belts, in the conveying region between the belts, the belt end of the belt arranged upstream is arranged laterally further inwards than the belt start of the belt arranged downstream, wherein at least one belt preferably runs laterally inclined with respect to the conveying direction. Thus, clogging of the strands of material and damage of the hose between the two belts is effectively prevented. This is particularly advantageous for devices for lateral guidance. In this context, "laterally further inward" means a position closer to the average longitudinal axis of the strands of transported material.

In an advantageous further embodiment, it is provided that the roller and/or the sliding plate is arranged between the two belts. The transport of the strands of material is then very easy to manage.

In an advantageous further embodiment, it is provided that the two continuous strips are arranged in an overlapping manner. The transport of the strands of material is then also very easy to manage.

In a further advantageous embodiment, provision is made for the strand guide to have one or more strand guide modules, wherein preferably at least two strand guide modules have the same design. The transport of the strands of material within the device can thus be particularly easily adjusted. In particular, this allows for the formation of an adjustable cantilever to dispense strands of material as required.

In an advantageous further embodiment, provision is made that the strand guide is designed to be pivotable with respect to a horizontal plane and/or with respect to a vertical plane. Thus, the strands of material can be dispensed particularly easily.

In a further advantageous embodiment, it is provided that a strand feed and a strand discharge are present, and that a hinge is provided between the strand feed and the strand discharge, by means of which hinge the strand discharge is pivotably arranged with respect to the strand feed. Thus, the material strands can be distributed particularly easily.

In an advantageous further embodiment, a transport device for transporting the apparatus is provided, wherein the transport device is preferably designed to be self-propelled, wherein the transport device is designed in particular to be telescopic. The device can thus be transported particularly easily, and furthermore, the device can independently dispense strands of material over a longer distance.

In an advantageous further embodiment, it is provided that there is a collecting container for providing the material, which collecting container is connected to the storage container via the transport equipment. For example, the conveying equipment may include a screw conveyor. In this way, a separate feeder may be omitted. Alternatively, for example, the truck may drive directly to the collection vessel and pour sand into the collection vessel. The sand is then transported to a storage vessel by means of transport equipment and made available for further use.

With the method according to the invention for producing a strand of flexible material, in particular a hose of material, the strand of flexible material is produced, transported and distributed.

Detailed Description

Fig. 1 to 4 show an apparatus 10 according to the invention for producing and dispensing strands 11 of flexible material (see fig. 5 and 5 a).

It can be seen that the apparatus 10 has, in addition to the equipment 12 for transporting strands of flexible material, a moving equipment 14 and a device 16 for producing strands of flexible material.

In this regard, the means 16 for producing comprises a storage or supply container 18 for material, in this example sand (not shown), means 20 for producing a material strand wrap 22 (see fig. 5 and 5 a), and means 24 for filling the material into the material strand wrap 22.

Furthermore, there is a housing 26, which housing 26 is rotatably arranged 27 with respect to the mobile equipment 14.

The device 20 for forming the material strand windings 22 has a support 28 for the winding material 30 to be held, a drawing shoulder (forming shoulder) 32 for forming the material strand windings 22 of tubular design, and a hose forming arrangement 34 for securing the material strand windings 22 and stabilizing the formed material strands 11.

The equipment 12 for transportation according to the invention has strand feeding means 36 and strand discharge means 38, the strand feeding means 36 being designed as a pull-out unit of the device 16 (for producing the strands 11 of flexible material), the strand discharge means 38 being connected to each other via hinge means 40.

In the rear part of the device 10 there is a supply 41 of electric and hydraulic power for the elements of the device 10.

The means 16 for producing strands 11 of flexible material, the strand feeding means 36 and the hinge means 40 are arranged on the housing 26 such that they can be rotated together relative to the mobile equipment relative to the vertical axis of rotation 27. Thus, these elements 16, 36, 40 may be aligned with the housing 26 in a horizontal plane (when the mobile equipment 14 itself is also positioned on a horizontal plane) as desired.

The hinge device 40 includes a vertical rotation axis 42 and a horizontal rotation axis 44. Thus, the strand discharge 38 may pivot relative to the longitudinal extension L of the housing 26, i.e., about the rotation axis 42, within an angular range of α= ±30° (see fig. 3), and relative to the horizontal plane H, i.e., about the rotation axis 44, within an angular range of β= ±15° (see fig. 4). However, a larger angular range of, for example, α, β= ±90° may also be used in each case.

With this device 10 according to the invention, strands 11 of flexible material can be produced and laid as desired, for example, to form the base 46 of the flood protection structure shown in fig. 5. Thus, such a flexible material strand 11 has a diameter of, for example, about 500mm, so that the flexible material strand 11 can be used to produce a base 46 that is about 2010mm high and about 2750mm wide and has an inclination angle δ=54.7°, which base 46 is sufficiently sized to form a dike (not shown).

The free rotation of the housing 26 and thus the equipment 12 for transporting the strands 11 of flexible material relative to the moving equipment 14, and the additional free pivoting of the strand ejection device 38 relative to the housing 26, allows the moving equipment 14 to move on a solid base while the produced strands 11 of flexible material can be freely handled and stacked to form the base 46.

However, instead of the housing 26 being freely rotatable about the rotation axis 27, it is also possible to provide a rigid arrangement of the housing 26 relative to the mobile equipment 14, whereby the material strand distribution is only affected by the pivotability of the strand discharge 38. This rigid design will have the advantage that: the supply container 18 will always remain in the same position, allowing the supply container 18 to be easily filled (e.g., by an excavator (not shown)).

In order to be able to fill the supply container 18 also directly from the truck, there may be, in addition to the supply container 18, a receiving container (not shown in fig. 1, 2, 3, 4 and 29, but see the device 10' of fig. 30) which is arranged so low on the device 10 that the receiving container can be easily filled directly from the truck. Additional transport means, for example in the form of a screw conveyor or conveyor belt, will then be provided to transfer material from the receiving container to the supply container 18 as required.

The arrangement 12 for transporting strands 11 of flexible material according to the invention will be described in more detail below in connection with fig. 6 to 11.

It can be seen that the pull-out unit 36 downstream of the hose forming equipment 34 has a frame 100 with a lower conveyor belt 102 and an upper conveyor belt 104 disposed directly above the lower conveyor belt 102 in the frame 100. The lower conveyor belt 102 forms a support and a first drive for the strands 11 of flexible material to be transported. The upper conveyor belt 104 also provides means for weighting the strands of flexible material 11 to be transported and second means for driving the strands of flexible material 11 to be transported. If the material strand 11 produced has a sufficient dead weight, this weighting with the upper conveyor belt 104 can be dispensed with if necessary.

The drives (not shown) of the lower conveyor belt 102 and the upper conveyor belt 104 are each electric motors that drive rollers for the conveyor belts 102, 104. Such driving rollers and associated guide rollers for the conveyor belts 102, 104 can thus be displaced from each other in their direction in order to be able to adjust the tension of the conveyor belts 102, 104.

Both the lower conveyor belt 102 and the upper conveyor belt 104 are stationary within the frame 100. However, it may also be provided that the upper conveyor belt is vertically displaceable at least on one side, preferably completely displaceable and displaceable in any orientation, in order thereby to be able to react to the height differences in the transported strands of flexible material 11.

Furthermore, there is a device 106 for laterally guiding the transported flexible material strands 11, the device 106 optionally being in the form of a plurality of vertically oriented drums or rollers arranged opposite each other with respect to the transported flexible material strands 11.

A removal unit 36, which pulls out the material strand 11 produced in the device 16 for producing flexible material strands 11 from the hose forming equipment 34, is provided for a stable discharge of the produced material strand 11, wherein the material strand 11 is simultaneously compressed and formed.

As can be seen in fig. 8, the strand ejection device 38 is designed as a cantilever with three cantilever modules 108, 108', 108″ of identical design. Each of such boom modules 108 has two lower conveyor belts 110 (see fig. 9) with an intermediate roller 112 disposed between each lower conveyor belt. Unlike conveyor belt 110, which can again be driven by drive roller 114 and a corresponding electric motor (not shown), intermediate roller 112 is mounted in a freely rotatable manner. As shown in fig. 9, the distance between the drive roller 114 associated with the conveyor belt 110 and the corresponding guide roller 116 may be varied to enable adjustment of the tension of the conveyor belt 110.

In addition, an upper conveyor belt (not shown) may be present to again weight the transported strands of flexible material 11.

An additional intermediate roller 118 is disposed between each two cantilever modules 108 as part of the strand ejector 38. In addition, such intermediate rollers 118a, 118b are also present on the boom module 108 in the direction towards the housing 26 and the last boom module 108″ in the transport direction.

Referring to fig. 10 and 11, it can be seen that the laterally vertically aligned guide rollers 120, 122 are disposed both laterally of the conveyor belt 110 and laterally of the intermediate roller 112, thereby preventing the transported strands of flexible material 11 from exiting the conveyor belt 110 and the intermediate rollers 112, 118.

In fig. 12, the device 10 according to the invention is shown in a partly produced state. It can be seen that the transfer of the strands 11 of flexible material from the not shown removal unit 36 to the not shown cantilever 38 is by means of three roller guides 124, 126, 128.

The first roller guide 124 is fixedly disposed on the housing 26. The second roller guide 126 is fixedly arranged on the rotary module 130 (see fig. 13, 14). And, the third roller guide 128 is fixedly disposed at the cantilever connector 132 (see fig. 15, 16).

The rotary module 130 has a rotary module housing 134, in which a roller guide 126, which is shown in fig. 13 but not in fig. 14 for ease of understanding, rests on a frame 136 and has a guide plate 138 with a front circular region 140 and a rear straight edge 142 and a freely rotatable roller 144 between the front circular region 140 and the rear straight edge 142.

In addition, the rotary module housing 134 has an upper connector 146 and a lower connector 148 for rotatably mounting 44 in the housing 26. Furthermore, there are bearings 150 on both sides for pivotable mounting 42 of the cantilever connector 132 in the rotary module 130.

Cantilever connector 132 has a cantilever connector frame 152 with a pivot support 154 received in support 150 to provide pivotable mount 42.

As can further be seen in fig. 15, 16, the third roller guide 128 in turn rests on the frame 156, wherein a freely rotatable roller 160 is arranged in the guide plate 158. In fig. 16, it can be seen that the mounting 162 of such a roller 160 is arranged below the guide plate 158.

The guide plate 158 of the cantilever connector 132 has straight edges 164, 166 on each side. Thus, in the assembled state (see fig. 12), the front straight edge 164 of the cantilever connector 132 faces the rear straight edge 142 of the rotary module 130, and the rear straight edge 166 faces the first intermediate roller 118a of the cantilever arm 38 (see fig. 8). Further, the front circular area 140 of the guide plate 138 of the rotation module 130 covers the first roller guide 124 (see fig. 12) such that there is a closed roller guide path 124, 126, 128, 118a for each case of possible horizontal and/or vertical pivoting of the cantilever arm 38 relative to the housing 26.

In order to prevent possible jamming of the strands of material 11 between the roller guides 124, 126, 128, 118a and the supports around the roller guides, the roller guides 124, 126, 128 or the intermediate roller 118a may also be omitted entirely, as appropriate, and only the supports 138, 158 are designed as sliding plates for the strands of material 11.

As can be seen in fig. 17, the rotary module 130 has a lever connector 168 on one side, on which lever connector 168 a hydraulic cylinder 170 is arranged (see also fig. 2), the other side of which is connected to the housing 26. Thus, horizontal pivoting of the cantilever 38 about the vertical axis 42 may be controlled.

As can be seen in fig. 18, the rotary module 130 has four stop points 172, 174, wherein the lower stop point 172 is arranged on the rotary module housing 134 and the upper stop point 174 is arranged on the cross beam 176. Such a cross member 176 is securely connected to the upper connector 146 via a shaft 178.

As can be seen in fig. 1 and 2, there is a rod 180, which rod 180 is connected to the rotation module 130, i.e. the lower stop point 172, and to the cantilever beam 38, in particular to the cantilever beam 38 at a cantilever stop point 182 fastened between the second cantilever module 108' and the third cantilever module 108 "(see fig. 8).

The lever 180 has two side portions 184, 186, each side portion 184, 186 having two lever portions 188, 190, wherein a cross brace 192 is present in the transition from the first lever portion 188 to the second lever portion 190, which cross brace 192 connects and supports the two side portions 184, 186.

There are in turn oppositely disposed stop points 194 on such a cross brace 192. Two controllable hydraulic cylinders 196 are connected in each case to the upper stop point 174 of the cross beam 176 and to the stop point 194 of the rod 186, so that the vertical pivoting of the boom 38 about the horizontal rotation axis 44 can be adjusted by targeted control of the hydraulic cylinders 196.

In order to be able to maintain the balance of the apparatus 10 in each case of horizontal pivoting of the cantilever 38 about the vertical axis 42, there is a counter-cantilever 198 on the cross beam 176, counter-cantilever 198 rotating counter to the cantilever 198, on which counter-cantilever 198 a suitable counterweight 200 is arranged. On the other hand, if the dead weight of the apparatus 10 on the side of the storage container 18 is sufficiently large, such additional counter-cantilevers 18 and counterweights 200 can also be dispensed with, as shown in fig. 1.

Fig. 19 shows a section through the hinge device 40 transversely to the longitudinal direction L, fig. 20 shows a top view of the hinge device 40 in the longitudinal direction L.

It can be seen that the rotation axis 42 is formed by two shafts 178, 202, each of which is firmly connected (by means of a key connection) to the housing 134 of the rotation module 130, and each of which is mounted in the housing 26 by means of spherical roller bearings 204, 206. Such spherical roller bearings 204, 206 can transmit particularly high forces without wear.

By using the separation shafts 178, 202, the rotation module 130 is configured as a cage through which the strands of material 11 can be easily transported throughout all pivot ranges.

Furthermore, the axes 42, 44 lie in one plane, which makes the hinge device 40 particularly efficient, space-saving and less abrasive.

In the cantilever connector 132, guides 207 in the form of sliding surfaces are provided laterally in each case in order to guide the material strands 11 laterally within the hinge device 40 and thereby center the material strands 11 such that a continuous transport of the material strands 11 is ensured even in the case of a large horizontal pivoting. However, the guide 207 may be formed of a roller or the like.

The mobile equipment 14 has two chains 208, 210 (see fig. 12), and the two chains 208, 210 may be driven individually (not shown) to achieve straight-line operation or reverse operation, as appropriate, and synchronization of turns with the respective ones. Furthermore, the chains 208, 210 have a lateral telescoping capability with respect to the chassis 212 so that the footprint of the mobile equipment 14 on the base may be adjusted as desired or may be reduced for transporting the device 10 on a semi-truck or the like (not shown).

Fig. 21 to 25 show the device 16 for production in more detail.

It can be seen that the device 20 for producing the material strand windings 22 has, in addition to the pulling shoulders 32, a hose forming arrangement 34, which hose forming arrangement 34 has a stitching device 220 and a stitch forming device 222. The forming shoulder (draw shoulder) 32 has a deflecting edge 224 for the wound material 30, which deflecting edge 224 delimits a guide tube 226, the guide tube 226 having a groove 228 tapering to a narrower gap at its upper end. The guide tube 226 is separated from the cylindrical-segment-shaped shelf 230 by a gap 229. Spaced from the shelf 230 is a gap 231 and a receiving tube 232 is coupled.

The suturing device 220 is designed as a horizontal flat seaming machine with a suturing direction (the direction of movement of the suturing needle along the longitudinal extension of the suturing needle). Accordingly, the suturing device 220 is preferably adapted to arrange two seams 233 in parallel.

By means of such a stitching device 220, the two outer edges of the wrapping material 30 that are put together in the groove 228 and that lie against each other in a vertical position are stitched together, so that the material strand wrap 22 is formed.

The stitch molding apparatus 222 is designed toMachines are described, for example, in publications DD 110 A1, DE 37 05 573 C2, WO 00/34561 A1 and DE 102 59 845 A1, the contents of which are incorporated by reference in their entirety. /(I)

More specifically, the suture molding apparatus 222 has four hook clips 234 (suture molding portions), each hook clip 234 being pivotally arranged about the gap 231 with respect to the longitudinal central axis of the shelf 230 such that one hook clip 234 always takes over entrained woven material of the hook clip 234 placed in front. Thus, the hose receiving tube 232 bearsThe task of the guide tube of the machine.

With these suture forming devices 222, the material strands 11 with the material strand windings 22 are surrounded by a suture structure 236, the suture structure 236 being formed by a row of sutures 238 extending parallel to the longitudinal axis of the material strands 11 and a strip of sutures 240 extending in a spiral fashion around the material strands 11, as shown in fig. 26.

This combination of seam 233 and stitch construction 236 cooperates with the material strand wrap 22 made of textile material to make the material strand 11 itself highly durable while being resilient during shipping and storage, yet flexible enough to be easily handled.

The gap 231 between the shelf 230 and the guide tube 232 provides an option for removing the suture structure 236 from the shelf 230 (if it has been created by the suture forming device 222 around the shelf 230) so that the strands of material 11 wrapped in the suture structure 236 may be transferred into the guide tube 232.

In one aspect, the shelf 230 is used to support and guide the strands of material 11 between the guide tube 226 and the hose receiving tube 232.

On the other hand, the shelf 230 serves for compacting the material in the strands of material 11, for which purpose the shelf is connected to a vibrator 242, which is designed for example as an electrically driven eccentric vibrator.

In addition, shelf 230 serves as a base for a fill level sensor 243, fill level sensor 243 comprising a rotatable wheel 243a or similar suitable sensor hinged to lever arm structure 243 b. By means of such a filling level sensor 243, the following parameters are controlled in dependence on the filling level in the flexible material strand 11: the filling amount, the joining speed of the opposite sides, the winding speed and the pulling-out speed are such that a predetermined filling level is maintained, preferably within a tolerance of the predetermined filling level.

The device 24 for filling sand stored in the storage vessel 18 has a housing 244, which housing 244 has an inlet 246 connected to the storage vessel 18 and an outlet tube 248 extending into the passage tube 226 without contacting the passage tube 226-thus, an annular gap (not shown) exists between the outlet tube 248 and the passage tube 226.

The means 24 for filling is designed as a screw conveyor, wherein one or more screws are present in the interior of the housing 244, which screws transport and compress the material from the storage container 18. Preferably, there are three intermeshing screws and an upper channel for transporting coarse material may be provided. For an embodiment of the device 24 for filling, reference is made to WO 2007/147540A1, the content of which is incorporated in its entirety in this respect.

In fig. 26, which fig. 26 shows a detailed view of a section in the horizontal plane above the lower conveyor belt 110, it can be seen that the transport of the material strands 11 is not interrupted, in particular from the removal unit (strand feeding device) 36 via the fixed guide plates 250 with the respective rollers 252, then via the guide plates 138 with the rollers 144, then via the guide plates 158 with the rollers 160, via the intermediate rollers 118b to the lower conveyor belt and the intermediate rollers 112 etc.

Fig. 26 also shows a control unit 254 of the device 10.

As can be seen in fig. 27, which fig. 27 shows a detailed view with a section through the vertical plane of the device 20 for producing material strand windings 20, the hose rack 230 engages under the guide tube 226 positioned upstream, wherein a gap 256 is formed. This prevents clogging of the hose 22 in the area between the hose shelf 230 and the guide tube 226, thereby ensuring safe hose delivery without damaging the hose 22.

It can also be seen that at the transition between the hose rack 230 and the hose receiving tube 232, the gap 231 is bridged by a shell element 258, which shell element 258 is arranged resiliently on the hose rack 230 and engages in the hose receiving tube 232. A gap 260 is provided between the housing element 258 and the hose receiving tube 232. Instead of such a shell element 258 or in addition to such a shell element 258, one or more fingers (not shown) may also be used.

This also ensures that the hose 22 can be forwarded without being jammed and damaged, wherein at the same time the hose can be wound through the device 20 in the area between the hose rack 230 and the hose receiving tube 232. In this case, the gap 231 is combined with the elastic shell member 258 to ensure that the winding is pulled out. The pull-out is particularly easy and safe due to the fact that the shell element 258 is of elastic design. In addition, the strands of material are also very easy to transport because the strands of material can slide over the shell member 258 and be supported by the shell member 258.

In fig. 28, in which an alternative embodiment of the strand discharge device 38 'of the apparatus 10 according to the invention according to fig. 1 is shown in a detailed view, it can be seen that, in the case of two continuous belts 110a, 110b, in the conveying region 262 between the belts 110a, 110b, the belt end 264 of the belt 110a arranged upstream is arranged vertically higher than the belt start 266 of the belt 110b arranged downstream, wherein both belts run in an ascending manner relative to the conveying direction F of the strand discharge device 38'. This results in a stepped transport of the material strands 11. Further, a sliding plate 268 is present in the conveying area 262 between the belts 110a, 110 b.

Thus, clogging of the strands 11 of material transported in the transport direction F and damage of the hose 20 between the two belts 110a, 110b is effectively prevented. The strands of material 11 are lifted from the upstream arranged belt 110a to the downstream arranged belt 110b over the sliding plate 268 by a stepped arrangement such that jamming is precluded.

Instead of the sliding plate 268 shown, a drum or roller (not shown) may be present as appropriate. Furthermore, there may optionally be no sliding plate 268 or rollers and thus a distance in the horizontal direction between the belts 110a, 110b, but instead there may be an overlap (not shown) between the belts 110a, 110b, so that the rollers or sliding plates 268 may optionally be omitted. Even when the horizontal distance between the belts 110a, 110b is not too great, the non-jam transfer will still function even without the provision of rollers or sliding plates 268.

In fig. 30 an alternative embodiment 10' of the device 10 according to the invention is shown, wherein only the differences are illustrated, as the other parts are identical.

It can be seen that such an apparatus 10' additionally comprises a collection container 300, which collection container 300 supplies the storage container 18 via a transfer arrangement 302. The conveying equipment 302 may comprise, for example, a belt conveyor. The collection container 300 and the transfer equipment 302 are arranged on a common platform 304, which platform 304 has its own carriage 306 and is connected to the rest of the device 10' via a coupling 308.

However, if the collection container 300 and the transfer apparatus 302 are secured to the rest of the device 10', the dedicated carriage 306 and coupler 308 may also be omitted.

With such additives 300, 302, a separate feeder may be omitted. Instead, for example, a truck may drive directly to collection vessel 300 and pour sand into collection vessel 300. The sand is then transported to the storage vessel 18 by means of the transport equipment 302 and is available for further use.

The device 10, 10' is now used as follows:

the apparatus 10, 10' is transported to and unloaded at the point of use by means of a low loader or the like. The space occupation is then brought to the desired size by means of the telescopic links 208, 210. The device 10, 10 'is then moved to its starting point, wherein the point is selected in such a way that the device 10, 10' finds a sufficient hold on the base, and furthermore the placement position of the strands 11 of flexible material is at a sufficiently small distance with respect to the cantilever 38.

The storage container 18 is filled with sand and refilled if necessary via a feeder (see apparatus 10) or via the collection container 300 and the transport equipment 302 (see apparatus 10') at the same time. The cantilever 38 is then pivoted such that the front end of the cantilever 38 is above the location where the strands 11 begin to be placed.

The wrapping material 30 is unwound from the support 28 and pulled into the guide tube 226 over a pull-out shoulder (forming shoulder) 32, forming it into a tube. The two lateral ends of the wrapping material 30 are thereby guided together by the slot 228 and are stitched thereon by the stitching device 220 to form the tube 22, the tube 22 also being first closed at its front end. Sand is then filled into the forming tube 22 by means of the filling device 24.

The hose 22 filled with material is guided over the shelf 230 and vibrated by the vibrator 242, thereby compacting the material in the hose 22.

The filled hose 22 is then enclosed in the suture structure 236 by the suture forming device 222, and the filled and enclosed hose 22 is then pulled out by the pulling device 36 and transferred to the cantilever 38 via the hinge unit 40.

In the pulling-out device 36, the contact pressure of the upper conveyor belt 104 is regulated, and furthermore, the speeds of the conveyor belt 110 of the boom 38 and the conveyor belts 102, 104 of the removal unit 36, as well as the speed of the hose forming equipment 34 and the speed of the filling device 24, are synchronized and regulated so as to produce a flexible material strand 11 which is uniformly filled with sand over the entire length and thus has a constant diameter (see fig. 29).

Thus, the fill level sensor 243 continuously monitors the fill level in the hose 22 and sets the following parameters: the filling quantity, the joining speed of the opposite sides, the winding speed and the withdrawal speed are controlled according to the filling level in the tube 22 such that the predetermined filling level is permanently reached, taking into account tolerances if necessary to ensure a constant quality.

After the flexible material strand 11 has reached the cantilevered front intermediate roller 188b and has reached the storage position from the front intermediate roller 188b, the apparatus 10, 10' is moved by means of the moving equipment 14 and/or the cantilever 38 is pivoted as required so that the flexible material strand 11 is placed continuously according to the planned placement path.

If a change in direction is to occur, in addition to the first flexible material strand 214, the feed rate of the feeder 24 may be reduced in advance for a period of time and/or the pull-out speed of the removal unit 36 and the transport speed of the cantilever 38 may be increased in advance for a period of time in order to create a second adjacent flexible material strand 216 or a third applied flexible material strand 218, thereby providing the flexible material strand 11 with less sand as filler on a certain section. The strands 11 of flexible material may then be bent 180 ° in this section to change direction.

If sufficient strand material 214, 216, 218 has been produced, the wrapping material 30 is cut and the rear end of the produced tube 22 is stitched and thereby closed, wherein the inner advancement of the apparatus 10, 10' is stopped.

Conversely, if additional strand material 214, 216, 218 is required after the wrapping material 30 has been completely consumed, additional rolls of wrapping material 30 are loaded and the beginning of the new wrapping material 30 is stitched to the end of the old wrapping material 30, wherein in doing so no progress is made within the apparatus 10, 10' until stitching has been completed. Subsequently, the described process can be performed again, whereby the annular tube 22 can in principle be produced in a highly reliable manner and the annular tube 22 placed as a sand-filled material strand 11.

In one aspect, the mobile equipment 14 may be used to transport the devices 10, 10'. On the other hand, the entire apparatus 10, 10' may also be transported on a low loader or the like. The moving device has a central part and a chain drive arranged thereon, wherein the chain drive can be moved out of or into the central part as the case may be. In the case of transport on a low loader, the movement in is then carried out so that the apparatus 10, 10 'remains as narrow as possible for transport on a highway or the like, while in the case of use the movement out is carried out so that the structural stability of the apparatus 10, 10' is ensured by the largest possible carrier base.

As is clear from the foregoing description, the present invention provides an option for producing strands 11 of flexible material, which avoids the drawbacks of the prior art. Thus, the material strands 11 can in principle be produced endless. Even if the diameter of the material strands 11 is large, a free handling of the material strands 11 is possible. Furthermore, the production is adjustable in terms of the dimensions of the material strands 11. Furthermore, the material strands 11 may be laid directly after production. This means that such flexible material strands 11 can be provided very easily and cost-effectively, for example for the construction of flood protection structures 46, protective military walls or for the targeted design of landscapes.

All features of the invention may be freely combined with each other, unless otherwise indicated. In particular, the features specified in the patent claims may also be combined with features from the group of features. Furthermore, the features described in the accompanying drawings can be freely combined with other features as features of the invention unless otherwise specified. Thus, the objective features of the device may also be used within the framework of the method in the form of method features, and the method features may be used within the framework of the device in the form of features of the device.
