Description

Description: The invention relates to a straightening machine for wire, rod or band-shaped straightening material made of steel, comprising a machine frame and several, preferably six or eight, straightening devices arranged on the machine frame for straightening the straightening material, at least two of the straightening devices being structurally different from one another differentiate in order to straighten straightened goods with different straightening good properties, preferably different thicknesses, and wherein one straightening device is provided per straightening device, via which a straightening good to be straightened can be fed to the straightening device.

Such straightening machines are known for example from the field of reinforced concrete construction and are used here to straighten steel wire unwound from reels for further processing in reinforcement elements. Straightening machines with more than one straightening device have the purpose of making it possible to process wire-shaped straightening material with different wire diameters, it being possible to switch back and forth between the wire diameters quickly and easily by providing several straightening devices. So far, it has been limited to a wire diameter range of 6 to 16 mm.

However, nowadays there is a need for a wire diameter range up to 20 mm. There are also country-specific differences in the required steel quality. For example, a different steel quality is required in Germany than in Austria. This poses a major challenge for companies operating in areas close to the border, since not only a certain wire diameter range must be covered, but also for different steel qualities.

Now you could consider taking this requirement into account by increasing the number of straightening devices accordingly. However, this will inevitably lead to a straightening machine with very large dimensions, which has further disadvantages. For example, the straightening machine can no longer be loaded into a transport container in order to be set up at another production location - in the case of mobile production systems.

[0005] WO 2015/149088 A1 discloses a feed and straightening device with a plurality of roller straightening devices. DE 196 13 087 A1 discloses a processing system for wire with a single rotor straightening device.

The objective technical object of the present invention is to provide a straightening machine according to the preamble of claim 1, which avoids the disadvantages of the prior art and allows greater flexibility in production while at the same time compactness of the straightening machine.

This object is achieved by a straightening machine according to the features of independent claim 1.

It is therefore provided according to the invention that the straightening devices are designed as rotor straightening devices, and that at least one feed device, preferably all feed devices, comprises a straightening material changing device with which at least one further straightening material to be straightened can be fed to the straightening device.

By providing a straightening device in at least one feed device, it is possible to increase the number of processable different straightening goods with almost the same machine size, thereby increasing the flexibility of production. At the same time, the machine can be prevented from coming to a standstill if a certain straightening good has been completely unwound from a reel and the old reel has to be replaced by a new one. By providing the straightening material changing device, a fresh strand of straightening material can already be clamped into the machine, which, when the old reel is running low, can be fed automatically to the assigned straightening device within a few seconds.

Patent office can be unwound provided.

In the position shown in Figure 1, a certain straightening material 2, 3, 4, 5, 6, and 7 is supplied to the straightening devices 8, 9, 10, 11, 12 and 13. In parallel, an alternate straightening material 2 ', 3', 4 ', 5', 6 'and 7' is provided in the straightening material changing devices 14 and 15, which instead of the straightening goods 2, 3, 4, 5, 6, and 7 of the respective straightening device 8, 9, 10, 11, 12 and 13 can be fed.

In the exemplary embodiment shown, the straightening device 8 is designed to straighten a straightening good 2 and 2 ′ with a specific thickness 25. As soon as the straightening good 2 has been completely unwound from the corresponding reel 36, a straightening good 2 'with the same thickness 25 can be fed to the straightening device 8 without the production process having to be interrupted for a long time. During processing of the straightening goods 2 ″ or one of the other straightening goods 3, 3 ″, 4, 4 ″, 5, 5 ″, 6, 6 ″, 7, 7 ″, the used reel 36 of the straightening goods 2 can be replaced during operation.

In comparison to the straightening device 8, the straightening device 13 is provided for straightening a straightening good 7 and 7 'with a different thickness 26.

The straightening device 11 is provided for straightening goods 5, 5 'with different thicknesses 27 and 28, with a change from the straightening goods 5 with a first thickness 27 to the straightening goods 5' with a second thickness 28 different therefrom Adaptation of the straightening device 11 to the different thickness 28 can be carried out.

The thicknesses 25, 26, 27 and 28 are examples of different properties of guide material.

Seen overall, the straightening machine 1 shown in FIG. 1, with the same size compared to the prior art, can process up to twelve different straightening goods instead of up to six different straightening goods in a quick and simple manner. It is easily conceivable to design the straightening device changing devices 14 and 15 such that three or more straightening goods can be fed to a certain straightening device instead of two straightening goods. In this way, the system can be scaled to almost any size.

The straightening machine 1 in the embodiment shown in FIG. 1 further comprises a separating device 18 in the form of a cutting device for separating a straightening material 2, 2 ', 3, 3', 4, 4 ', 5, 5', 6, 6 ', 7, 7' with a certain length 19 and a feed device 20, 21 for transporting the straightening goods 2, 2 ', 3, 3', 4, 4 ', 5, 5', 6, 6 ', 7, 7' into a feed device 22, the separating device 18 and the feed device 20, 21 defining a production line 23.

Specifically, the feed device 20, 21 in the shown state of the straightening machine 1 transports the straightening material with the reference number 4 from the unwinding device 16 to the straightening device 10, through this straightening device 10 and to the separating device 18. Is the straightened straightening material 4 with a desired Length 19 far enough out of the separating device 18, the separating device 18 is activated and the directed straightening material 4 with the length 19 is separated from the rest of the straightening material strand.

If, instead of the straightening goods 4, the straightening goods 4 'stored in the straightening goods changing device 14, 15 of this straightening device 10 are to be fed to the straightening device 10, the straightening goods changing device 14, 15 becomes active as described below.

Alternatively, one of the straightening goods 2, 3, 5, 6, and 7 can be fed to the production line 23, namely by the carrier 17, on which the straightening devices 8, 9, 10, 11, 12 and 13 and the associated Feed devices 14, 15 are arranged, is adjusted relative to the separating device 18 and the feed device 20, 21. The adjustment takes place essentially transversely to the feed direction 22. This direction is identified in FIG. 2 by the reference number 37. In this case, one of the other straightening devices 8, 9, 11, 12 or 13 is then active instead of the straightening device 10.

Patent Office [0040] A change between the straightening goods 2 and 2 ″, 3 and 3 ″, 5 and 5 ″, 6 and 6 ″ or 7 and 7 ″ can then also be carried out via the respective straightening goods changing device 14, 15.

Viewed overall, each of the stored goods 2, 2 ', 3, 3', 4, 4 ', 5, 5', 6, 6 ', 7, 7' can thus be supplied to the production line 23 within a very short time by the action of a straightening device changing device 14, 15 of one of the straightening devices 8, 9, 10, 11, 12 or 13 and / or by an adjustment of the carrier 17 relative to the separating device 18 and the feed device 20, 21.

FIG. 2 shows a straightening machine 38 according to a second preferred embodiment. The structure is essentially the same as for the straightening machine 1 according to FIG. 1. However, a fundamental difference is that instead of a single production line 23, two production lines 23 are now provided. The common carrier 17 takes up a position relative to the two production lines 23 in the state shown, in which the straightening goods 3 and 6 directed by the straightening devices 9 and 12 are fed to the production lines 23.

The provision of a plurality of production lines 23 has the advantage that it can be directed in parallel operation, which in the same time enables two output lines 23 to double, three output lines 23 to triple and so on.

As can be seen from FIG. 3a, the feed device 20, 21 comprises two pairs of rollers 20 and 21, each of which is composed of a drivable roller 29 and a counter roller 30 cooperating therewith. By rotating these rollers 29 and 30 in opposite directions, it is possible to direct a product 4, which is located between the two rollers, in the feed direction 22, that is, in the direction of the straightening device 10 and through it in the direction of the separating device 18 (see FIG. 1). to transport. The drivable rollers 29 are driven by an electric motor 42 (see FIG. 3b). The circumferential sides of the drivable rollers 29 have a corrugation in order to increase the friction with the target material 4 to be driven. The counter rollers 30 are not actively driven themselves. Rather, they rest non-positively on the straightening good 4 and automatically rotate in the opposite direction by the movement of the straightening good 4 in the feed direction 22.

As can be seen from FIG. 3b, the straightening material changing device 14, 15 can be designed such that it has a guide device 14 and a releasable clamping device 15. The guiding device 14 and the releasable clamping device 15 are each constructed in two parts, a first part 43 and 45 of the guiding device 14 serving to guide the straightening good 4 and a second part 44 and 46 of the guiding device 14 serving to guide the exchangeable straightening good 4 '. Accordingly, the releasable clamping device is also divided into two, a first part 47 cooperating with the target 4 and a second part 48 with the target 4 '. The components 43 and 45 of the first part of the guide device 14 and the components 44 and 46 of the second part of the guide device 14 are each arranged adjacent and opposite one another relative to the drivable roller 29 of the roller pair 21.

The two parts 47 and 48 of the releasable clamping device 15 can assume two states, namely a state in which the target 4 or 4 'is held by the releasable clamping device 15, and a state in which the target 4 or 4 4 'can move freely through the releasable clamping device 15.

Figures 4a and 4b schematically show one of the pairs of rollers formed from the drivable roller 29 and the counter roller 30 cooperating therewith, namely in Figure 4a in the feed position 31 and in Figure 4b in the change position 33.

In the feed position 31, the drivable roller 29 takes up a first distance 32 relative to the counter roller 30, which essentially corresponds to the thickness of the straightening material 4 arranged between the rollers 29 and 30. The rollers 29 and 30 are non-positively or frictionally against the straightening good 4 and can thus convey it by a counter-rotating movement.

AT 518 731 B1 2019-05-15 Austrian

Patent Office In the change position 33, the drivable roller 29 takes a second, larger distance 34 to the counter roller 30. This means that a further straightening good 4 '- or 2, 2', 3, 3, 5, 5 ', 6, 6', 7, 7 '- can be exchanged into the feed device 20, 21 and thus can be fed to the production line 23 ( compare Figure 1 or 2).

Specifically, a first straightening goods 2, 2 ', 3, 3', 4, 4 ', 5, 5', 6, 6 ', 7, 7' located in the production line 23 can be replaced by a second straightening goods 2 as follows , 2 ', 3, 3', 4, 4 ', 5, 5', 6, 6 ', 7, 7': First, the straightening material 2, 2 ', 3, 3' currently in production line 23 is , 4, 4 ', 5, 5', 6, 6 ', 7, 7' by means of the corresponding feed device 20, 21 pushed past the active straightening device 8, 9, 10, 11, 12, 13. The pairs of rollers of the feed device 20, 21 are in the feed position 31. The releasable clamping device 15 is open. The pairs of rollers of the feed device 20, 21 then move from the feed position 31 into the change position 33. The releasable clamping device 15 closes and is adjusted together with the guide device 14 essentially transversely to the feed direction 22, namely until the adjoining material to be straightened out 2, 2 ', 3, 3', 4, 4 ', 5, 5', 6, 6 ', 7, 7' between the roller pairs of the feed device 20, 21. If the substituted straightening material 2, 2 ', 3, 3', 4, 4 ', 5, 5', 6, 6 ', 7, 7' is a straightening material with different straightening properties 25, 26, 27, 28 if necessary, an adjustment of the straightening device 8, 9, 10, 11, 12, 13 to the different properties of the straightening material 25, 26, 27, 28 is carried out at the same time. Subsequently, the pairs of rollers of the feed device 20, 21 move from the change position 33 to the feed position 31. The releasable clamping device 15 is opened and the feed device 20, 21 can replace the inserted straightening material 2, 2 ', 3, 3', 4, 4 ', 5, 5', 6, 6 ', 7, 7' in direction 22 of the straightening device 8, 9, 10, 11, 12, 13, convey through this and to the separating device 18. If necessary, the rest of the old straightening goods 2, 2 ', 3, 3', 4, 4 ', 5, 5', 6, 6 ', 7, 7' will finally be removed from production line 23 with the help of the new straightening goods 2, 2 ', 3, 3', 4, 4 ', 5, 5', 6, 6 ', 7, 7' pushed out. This remainder can just as easily be removed manually or with another tool.

It should also be pointed out that the direction in which the guide device 14 and the releasable clamping device 15 can be adjusted in the course of the changing process is provided with the reference number 35 in FIGS. 1, 2 and 3b. This direction is essentially parallel to the adjustment direction 37 of the common carrier 17 in the course of a change between the straightening devices 8, 9, 10, 11, 12, 13, which is analogous to a change between straightening goods 2, 2 ', 3, 3' , 4, 4 ', 5, 5', 6, 6 ', 7, 7', with which a single straightening device 8, 9, 10, 11, 12, 13 can be supplied.

Figure 5a shows again the straightening machine 1 according to the first preferred embodiment (see Figure 1). FIG. 5 b shows this straightening machine 1 in a cross-sectional illustration, the straightening machine 1 being additionally arranged in a transport container 54. The transport container 54 has a width 41 of 2350 mm and a height 55 of 2600 mm. The machine frame 51 of the straightening machine 1 is adapted to these dimensions of the transport container 54, so that the straightening machine 1 can be arranged in the transport container 54. In order to maximize the available space, the straightening devices 8, 9, 10, 11, 12 and 13 are arranged on a line 58, shown in broken lines. This includes an angle 40 of approximately 45 ° to the substrate 56. The six straightening devices 8, 9, 10, 11, 12 and 13 are arranged on a common carrier 17. This can be around the straightening material 2, 2 ', 3, 3', 4, 4 ', 5, 5', 6, 6 ', 7, 7 directed by a certain straightening device 8, 9 10, 11, 12 or 13 'to the production line 23, can be adjusted in a direction 37 transverse to the feed direction 22.

Figure 6a shows a straightening machine 49 according to a third preferred embodiment. An essential difference from the second preferred embodiment (see FIG. 2) is that the straightening machine 49 comprises eight straightening devices 8, 9, 10, 11, 12, 13, 52 and 53. These are arranged on a common support 17 and can be fed to two production lines 23 by adjusting the support 17.
