- FIG. 11 shows a known device for producing a container 10, in particular a silo, from a helically bent sheet metal strip 20.
- a device for example, in EP 1 181 115 B1, EP 3 189 906 A1 or EP 3 189 908 A1.
- the sheet metal strip 20 is pulled off a reel 18 and first fed to a forming device 25.
- This forming device 25 produces a fold of the upper edge area of the supplied sheet metal strip 20 via individual forming stations, so that as a result an outwardly pointing flange in the upper edge area of the
- Sheet metal strip 20 is present.
- the forming device 25 causes the plane of the supplied sheet metal strip 20 to be curved, essentially corresponding to the radius of curvature of the container 10 to be created.
- the forming device 25 also has its own drive unit to ensure the advancement of the sheet metal strip 20.
- the profiled and curved sheet metal strip 20 is then fed to a drive device 40, to which a mounting frame 32 is connected, which, when viewed from above, is of cylindrical circumferential design and on which the lower
- Edge area of the respectively fed lower sheet metal strip 20 is rotatably mounted.
- a connecting device 50 which is designed as a welded connection device and welds the respective lower sheet metal edge of the existing, already assembled container construction to the upper sheet metal edge of the sheet metal strip 20 that is fed in.
- two further drive units 28 are also provided at a distance in the circumferential direction.
- the sheet metal strip 20 fed in, with its curvature and edge profiling, runs helically upwards to form the outer surface of the container 10.
- this forming device 25 Since the forming device 25 performs both the curvature and the complete profiling of the sheet metal strip 20 that is fed in and has its own drive, this forming device 25 is relatively bulky and heavy.
- the diameter of the container 10 is indicated by the reference character D in FIG.
- silos with a diameter of 10 meters up to 50 meters or larger can be created with such devices.
- Figs. 1 and 2 show an apparatus for producing a
- Container 10 made of a helically bent sheet metal strip, which works on the same principle as the known device according to FIG.
- Forming device 25 is replaced by a profiling device 30.
- the profiling device 30 is connected to a feed device 60.
- the profiling device 30 is significantly reduced in volume and weight compared to the known molding device, since it does not have its own drive, which has a favorable effect on the transport and assembly of the profiling device 30 with the feed device 60.
- FIGS. 3 to 6 An exemplary embodiment of the feed device 60 is shown in FIGS. 3 to 6.
- the feed device 60 has a guide frame 48, which in the illustrated embodiment in cross-section in the

- the tension member 46 is in operative connection with an actuating unit, which in the illustrated embodiment as
- Handwheel device 22 is formed. By rotating the
- a tensile force is exerted on the tension member 46 due to the existing rotational interlocking, which is transmitted to the connected sheet metal strip 20 and thereby causes a movement of the sheet metal strip 20 in the longitudinal direction L.
- the actuation unit or the handwheel device 22 is present in the area of the drive device 40 such that when the actuation unit (handwheel device 22) is actuated, the sheet metal strip 20 is pulled into the drive device 40 so far that the sheet metal strip 20 is grasped by it and can be transported further.
- the feed device 60 is used at the start of the manufacturing process for the container 10. In practice it works as follows.
- the sheet metal strip 20 is withdrawn from the reel 18, which is rotatably mounted, and fed to the profiling device 30. As soon as the sheet metal strip 20 is in contact with the profiling device 30, the tension member 46 is connected to the end face of the sheet metal strip 20. Then the sheet metal strip 20 is pulled by actuating the actuating unit (handwheel device 22) further in the longitudinal direction L and pulled through the profiling device 30 with its profiling stations 30.1, whereby the profiling of the upper in the embodiment
- Sheet metal edge of the sheet metal strip 20 is carried out gradually.
- the actuation unit (handwheel device 22) is activated until it is at least partially profiled in its upper edge area Sheet metal strip 20 is fed to the drive device 40. As soon as this feed has taken place, the tension member 46 is released and the further transport of the sheet metal strip 20 for producing the outer surface of the container 10 is taken over by the drive device 40.
- the profiling device 30 is designed as a lightweight structural unit, since it does not cause the sheet metal strip 20 to bend and there is no drive unit. The sheet metal strip 20 is thus fed to the drive device 40 in a straight line and the
- Sheet metal strip 20 connected to one another by means of the connecting device 50.
- the connecting device 50 In the illustrated embodiment, the
- Connection device 50 designed as a weld connection device.

- guide units 44 are provided on the guide frame 48 in which the lower edge area of the fed sheet metal strip 20 is guided during the linear longitudinal displacement in the L direction by the feed device 60 . This also increases the stability of the feeding process.
- the tension member 46 can also be used as a cable unit, profile unit or
- the hand wheel device 22 is operated manually. It is also possible to activate the tension member 46 by an additionally available motor-driven unit in order to initiate the longitudinal displacement L of the sheet metal strip 20 at the beginning of the assembly process until it has reached the drive device 40. The drive unit is then switched off and the tension member 46 is decoupled from the sheet metal strip 20.
- Wheel device 22 (manually or motorized) with tension member 46 is dispensed with and a light drive unit is arranged on the profiling device 30 in its place, which ensures the propulsion of the sheet metal strip 20 via the profiling device 30 to the drive device 40. As soon as the sheet metal strip 20 is grasped by the drive device 40, this lightweight unit is then switched off and decoupled from the advance of the sheet metal strip 20.
- FIG. 2 a container 10 is shown which has been created using the device according to FIG. 1 and which shows four layers of sheet-metal strips that are connected to one another in a helical manner.
- the upper and lower sheet metal strip layer is cut freely in a horizontal section so that, on the one hand, reliable storage in the lower area and, on the other hand, a problem-free roof structure in the upper area is guaranteed.
- FIGS. 7 to 10 show in detail the device according to FIGS. 1 and 2 with feed device 60, profiling device 30, drive device 40 and connecting device 50 with sheet metal strip 20 fed by feed device 60 up to shortly before drive device 40.
- the actuation unit (handwheel device 22) is arranged in the middle of the drive device 40 with its four drive units 41.1, 41.2, 41.3, 41.4.
- the sheet metal strip 20 is fed to the drive device 40 via the feed device 60 supplied, the upper edge region of the sheet metal strip 20 already having a partial profiling due to the profiling device 30, to the effect that an outwardly facing flange is formed on it.
- this flange is deformed into its final shape by additional profiling units, the sheet metal strip 20 is shaped into a curvature corresponding to the curvature of the container 10 to be created and then fed to the connecting device 50, which connects the shaped top of the fed sheet metal strip 20 with the underside of the in FIGS. 7 to 10, the lower edge region, not shown, of the already existing sheet metal strip 20 connects by means of welding.
- the inventive device for producing a container 10 from a helically bent sheet metal strip 20 differs from the known solution in that the known Formein direction is replaced by a simple and lightweight profiling device 30, the sheet metal strip 20 passing through the feed device 60 at the beginning of the manufacturing process the profiling device 30 is fed to the drive device 40, at the same time at least partial profiling of the edge region of the sheet metal strip being carried out without having to use a shaping device which has a high volume and a high weight.
- This offers advantages in terms of economical production, particularly in the case of thin-walled containers.
- the device according to the invention is characterized by a low transport volume, low weight, high variability with regard to the assembly process and economic use.
