- the rod 180 has two sides 184, 186 each with two rod parts 188, 190, with a cross brace 192 in the transition from the first rod part 188 to the second rod part 190, which connects the two sides 184, 186 with each other and stiffens them.
- FIG. 19 shows a section through the joint means 40 transversely to the longitudinal direction L and
- FIG. 20 shows a plan view of the joint means 40 in the longitudinal direction L.
- the axis of rotation 42 is formed by two shafts 178, 202 which are each firmly connected (by means of feather key connections) to the housing 134 of the rotary module 130 and are each supported in the housing 26 with spherical roller bearings 204, 206.
- These spherical roller bearings 204, 206 can transmit particularly high forces without wear.
- the rotary module 130 is constructed as a cage through which the material strand 11 can be easily transported for all pivoting areas.
- the axes 42, 44 lie in one plane, as a result of which the joint means 40 are designed to be particularly effective, space-saving and low-wear.
- guides 207 in the form of sliding surfaces are provided laterally in order to guide the material strand 11 laterally within the articulation means 40 and thereby center it, so that a steady transport of the material strand 11 is guaranteed even with larger horizontal pivoting.
- the guides 207 could, however, also be formed by rollers and the like.
- the movement device 14 has two chains 208, 210 (cf. FIG. 12), which can be driven separately (not shown) in order to enable both straight running or reverse running as well as cornering with appropriate synchronization.
- the chains 208, 210 can be telescoped to the side with respect to the chassis 212, so that the standing surface of the movement device 14 on a surface can be adjusted if necessary or the standing surface for the transport of the device 10 on a tractor or the like (not shown ) can be reduced.
- FIGS. 21 to 25 the means 16 for manufacturing are shown in greater detail.
- the means 20 for producing the material strand covering 22 have, in addition to the pulling shoulder 32, a hose-forming device 34 which has sewing means 220 and loop-forming means 222.
- the forming shoulder (pulling shoulder) 32 has a deflection edge 224 for the wrapping material 30, which delimits a guide tube 226 which, at its upper end, has a slot 228 which tapers down to a narrow gap.
- the guide tube 226 is spaced apart from a cylinder segment-like tray 230 by a gap 229. At a distance from the tray 230 by a gap 231, a receiving tube 232 adjoins it.
- the sewing means 220 are designed as a lockstitch machine whose sewing direction (direction of movement of the sewing needle along the longitudinal extension of the sewing needle) is horizontal.
- the sewing means 220 are preferably adapted to set two seams 233 in parallel.
- the loop-forming means 222 are designed as Kemafil ® machines, as described for example in the publications DD 110 905 A1, DE 37 05 573 C2, WO 00/34561 A1 and DE 102 59 845 A1, the relevant content of which is fully referred to is taken.
- the stitch-forming means 222 have four hook grippers 234 (mesh-n-forming parts), each around the gap 231 with respect to a longitudinal central axis of the tray 230 are arranged pivotably so that a hook gripper 234 always takes over the braided material of the hook gripper 234 placed in front of it.
- the tube receiving tube 232 takes on the task of Fendingu ngsrohres a Kemafil ® machine.
- the material strand 11 with the material strand cover 22 is surrounded by a mesh structure 236, which is formed from rows of stitches 238 running parallel to the longitudinal axis of the material strand 11 and wales 240 running spirally around the material strand 11, as shown in FIG. 26 .
- the material strand 11 itself is very durable and at the same time resilient during transport and storage and is nevertheless flexible so that it can be easily manipulated.
- the gap 231 between the shelf 230 and the guide tube 232 allows the mesh structure 236 to be withdrawn from the shelf 230 (if this is already generated around the shelf 230 by the mesh-forming means 222), so that the strand of material encased in the mesh structure 236 11 can be transferred into the guide tube 232.
- the tray 230 serves on the one hand to support and guide the material strand 11 between the guide tube 226 and the hose receiving tube 232.
- the tray 230 serves to compress the material in the material track 11, for which purpose the tray is connected to a vibrator 242, which is designed, for example, as an electrically driven eccentric vibrator.
- the shelf 230 serves as the basis for a level sensor 243, which comprises a rotatable wheel 243a or a similarly suitable sensor, which is articulated on a lever arm construction 243b.
- a level sensor 243 which comprises a rotatable wheel 243a or a similarly suitable sensor, which is articulated on a lever arm construction 243b.
- the parameters: filling quantity, connection speed for the opposite sides, wrapping speed and withdrawal speed depending on the level in the flexible material strand 11 are regulated so that a predetermined level, preferably within a tolerance range for the predetermined level is maintained.
- the means 24 for filling the sand stored in the storage container 18 have a housing 244 with an inlet 246, which is connected to the storage container 18, and an outlet pipe 248 which extends into the feed-through pipe 226 without touching it - it therefore exists an annular gap (not shown) between outlet pipe 248 and feed-through pipe 226.
- the means 24 for filling are designed as screw conveyors, with one or more screws inside the housing 244 which transport and compress the material from the reservoir 18 Vorratsbe. Preferably there are three intermeshing augers and an upper channel can be provided in which coarse material is transported.
- WO 2007/147540 A1 the relevant content of which is included in full.
- Fig. 26 which shows a detailed view with a section in the horizontal plane above the lower conveyor belts 110, it can be seen that the transport of the material strand 11 takes place without interruption, namely from the take-off unit (strand feed means) 36 via a fixed guide plate 250 with corresponding Rollers 252, then over the guide plate 138 with the rollers 144, then the guide plate 158 with the rollers 160, via the intermediate roller 118b to the lower conveyor belt and intermediate roller 112, etc.
- the control unit 254 of the device 10 can also be seen in FIG.
- FIG. 27 which shows a partial detailed view with a section in a vertical plane through the means 20 for producing the material strand sheathing 20, it can be seen that the hose holder 230 engages under the upstream guide tube 226, with a gap 256 being formed. This prevents the hose 22 from jamming in the area between the hose holder 230 and the guide tube 226, which ensures that the hose 22 is reliably conveyed without damaging the hose 22. It can also be seen that the gap 231 at the transition between hose holder 230 and hose receiving tube 232 is bridged by a shell element 258 which is resiliently arranged on hose holder 230 and engages in hose receiving tube 232. A gap 260 is formed between this shell element 258 and the hose receiving tube 232. Instead of or in addition to this shell element 258, one or more fingers (not shown) can also be used.
- the conduction of the hose 22 is also ensured here without being damaged by jamming, and at the same time the means 20 can be wrapped around in the area between the hose holder 230 and the hose receiving tube 232.
- the gap 231 in connection with the resilient shell element 258 ensures that the wrapping is pulled off.
- the fact that the resilient shell element 258 is present means that it can be pulled off particularly easily and safely.
- the strand of material is also very easily transported because it can slide over the shell element 258 and is supported by it.
- Fig. 28 in which an alternative embodiment of the strand removal means 38 'of the inventive device 10 according to FIG. 1 is shown in a detailed view, it can be seen that with two successive belts 110a, 110b in the transfer area 262 between the belts 110a, 110b the belt end 264 of a belt 110a arranged upstream is arranged vertically higher than the beginning 266 of a belt 110b arranged downstream, both belts increasing in relation to the conveying direction F of the strand discharge means 38 '. This results in a more or less step-shaped transport of the material strand 11.
- the transfer area 262 there is a sliding plate 268 between the belts 110a, 110b.
- roller instead of the slide plate 268 shown, there could also be a roller (not shown).
- the sliding plate 268 or roller instead of the sliding plate 268 or roller and thus in In the horizontal direction between the belts 110a, 110b there is also an overlap (not shown) between the belts 110a, 110b, so that rollers or sliding plates 268 can be dispensed with. Even if the horizontal distance between the belts 110a, 110b is not too great, the jam-free transfer will still work, even if no roller or slide plate 268 is provided.
- FIG. 30 an alternative embodiment 10 'of the device 10 according to the invention is shown, only the differences being explained below, because otherwise parts are the same.
- this device 10 ′ additionally comprises a collecting container 300 which feeds the storage container 18 via a conveying device 302.
- the conveyor device 302 can be, for example, a belt conveyor. Collection container 300 and conveyor device 302 are arranged on a common platform 304 which has its own chassis 306 and is connected to the rest of the device 10 'via the coupling 308.
- a separate chassis 306 and the coupling 308 could also be dispensed with if the collecting container 300 and the conveying device 302 were permanently connected to the rest of the device 10 '.
- a separate feeder can be dispensed with.
- trucks can drive directly to the collecting container 300 and dump sand into it.
- the sand is then transported to the storage container 18 by means of the conveyor device 302 and is available for further use.
- the device 10, 10 ' is brought to the place of use by means of a low loader or the like and is unloaded there.

- the storage container 18 is filled with sand and, in the meantime, if necessary, refilled again via a feeder (see device 10) or via the collecting container 300 and the conveying device 302 (see device 10 ').
- the boom 38 is pivoted so that its front end is above the point at which the beginning of the material train 11 is to be deposited.
- the wrapping material 30 is unrolled from the bearing 28 and pulled over the pulling shoulder (form shoulder) 32 into the guide tube 226 and thereby formed into a tube.
- the two lateral ends of the wrapping material 30 are guided together through the slot 228 and sewn over it with the sewing means 220 to form the tube 22, which was also first closed at its front end. Then sand is filled into the hose 22 formed by means of the filling means 24.
- the tube 22 filled with material is guided over the tray 230 and vibrated with the vibrator 242, as a result of which the material in the tube 22 is compressed.
- the filled hose 22 is sheathed with the mesh-forming means 222 with the mesh structure 236 and the filled and sheathed hose 22 is then pulled off by the pulling means 36 and conveyed to the boom 38 via the hinge unit 40.
- the contact pressure of the upper conveyor belt 104 is adjusted and the speeds of the conveyor belts 110 of the boom 38 and the conveyor belts 102, 104 of the extraction unit 36 as well as the speed of the hose formation device 34 and the speed of the filling means 24 are synchronized and adjusted so that a flexible material strand 11 results (cf. FIG. 29), which is evenly filled with sand over its entire length and thus has a constant diameter.
- the fill level in the hose 22 is continuously monitored by the fill level sensor 243 and the parameters: fill quantity, connection speed for the opposite sides, wrapping speed and take-off speed depending on the fill level in the hose 22 are regulated in such a way that a preset fill level, if necessary, taking into account a tolerance, is achieved permanently in order to guarantee constant quality.
- the device 10, 10 ' is moved, if necessary, by means of the movement device 14 and / or the boom 38 is pivoted so that the flexible material strand 11 is successively the planned Filing path is stored accordingly.
- the filling speed of the filling means 24 and / or the withdrawal speed can be reduced in advance for a certain time the haul-off unit 36 and the transport speed of the boom 38 can be increased, as a result of which the flexible material strand 11 has less sand as a filling over a certain section.
