Abstract

A production system for processing a wire material wound to form a wire reel, in particular reinforcing steel. The production system comprises a receiving device for receiving the wire reel; an unreeling device for removing the wire material on the wire reel; and a processing device for processing the removed wire material. The unreeling device comprises a conveyor surrounding a first deflection roller and a second deflection roller, wherein permanent magnets are arranged on the conveyor and an increased frictional connection can be established between a surface of the wire material and an outer surface of the conveying means by means of the permanent magnets.

Description

The invention relates to a production system for processing a wire material wound to form a wire reel, in particular concrete-reinforcing steel.
From the state of the art, it is known that concrete-reinforcing steel, which is wound up to form a wire reel, is unwound in a production system in that the wire reel is driven and the concrete-reinforcing steel is actively unwound. In addition, it is provided that a conveying apparatus is configured, on which two rollers that lie opposite one another are provided, between which the wire material is clamped. At least one of the two rollers is driven, in this regard, and a tensile force can be exerted on the wire material by means of the friction fit between roller and wire material, in order to be able to further convey the wire material unwound from the roller.
The unreeling apparatus known from state of the art has the disadvantage that, in particular in the case of concrete-reinforcing steel, a relative movement can come about between the driven roller and the wire material, due to the rough surface structure of the material, i.e. its ribbed surface. Therefore such a conveying apparatus can have only a low precision. Furthermore, the maximally possible pulling force of the unreeling apparatus is limited because of the poor contact between the ribbed surface of the concrete-reinforcing steel and the driven roller.
It was the task of the present invention to overcome the disadvantages of the state of the art and to create an improved production system for processing a wire material wound to form a wire reel.
This task is accomplished by means of a production system according to claim 1.
According to the invention, a production system for processing a wire material wound to form a wire reel, in particular concrete-reinforcing steel is configured. The production system comprises: an accommodation apparatus for accommodating the wire reel; an unreeling apparatus for pulling off the wire material situated on the wire reel; and a processing apparatus for processing the pulled-off wire material. The unreeling apparatus comprises a conveying means that runs around a first deflection roller and a second deflection roller, wherein permanent magnets are disposed on the conveying means, and an increased friction fit between a surface of the wire material and an outer surface of the conveying means can be produced by means of the permanent magnets.
An advantage of the configuration according to the invention is that the unreeling apparatus having the circulating conveying means and the permanent magnets disposed in it can apply an increased tensile force on the wire material to be unwound from the wire reel. Furthermore, the length of the wire material unwound from the wire reel can be determined with great precision by means of the unreeling apparatus configured according to the invention. In particular in the case of concrete-reinforcing steel having a rough surface, the precision as compared with conventional conveying apparatuses having clamping rollers can be significantly improved in this way. Furthermore, it can be provided that the accommodation apparatus for accommodating the wire reel is driven, and thereby unreeling of the wire material is facilitated.
Furthermore, it can be practical if the conveying means of the unreeling apparatus is configured as a conveyor belt. In particular, it can be provided that the unreeling apparatus is configured as a belt conveyor. It is advantageous, in this regard, that a conveyor belt can demonstrate great flexibility, and furthermore can demonstrate good aging resistance. Furthermore, the conveyor belt can be formed from a rubber-like material, and thereby an increased riding fit can be produced between the outer surface of the conveyor belt and the surface of the wire material.
Furthermore, it can be provided that the accommodation apparatus is configured for accommodating a raw material roller, wherein the wire material wound in the manner of a reel is disposed on the raw material roller. It is advantageous, in this regard, that the wire material is not tensioned directly on the accommodation apparatus, but rather a standardized raw material roller can be used, which can be accommodated on the accommodation apparatus.
Furthermore, it can be provided that the accommodation apparatus has a braking mechanism, by means of which the wire material of the wire reel is tightened during the unreeling process. It is advantageous, in this regard, that the wire material does not run off from the wire reel in uncontrolled manner, and thereby tangling of the wire material on the wire reel is counteracted.
An embodiment according to which it can be provided that the unreeling apparatus is disposed in the production system in such a manner that the wire material is passed to the processing apparatus in an arc is also advantageous. This brings with it the advantage that the processing apparatus, which follows the unreeling apparatus, does not need to be operated synchronously with the unreeling apparatus, but rather the arc of the wire material forms an intermediate buffer, and thereby the processing speed and the flexibility of the production system can be increased. Expressed in other words, the wire material is made available in a loose loop, which forms the intermediate buffer, and thereby the wire material can be pulled off in a load-free state. In particular, the result can be achieved, by means of this measure, that the wire reel, which demonstrates great mass inertia, does not constantly have to be put into motion at great acceleration values. Aside from the energy savings that can be achieved, the longevity of the production system can also be improved by means of this measure.
According to a further development, it is possible that the processing apparatus is configured as a straightening system for straightening the wire material. It is advantageous, in this regard, that the unwound wire material can be prepared in the processing apparatus for further processing in all types of production systems for processing of straight round material rods. Such a production system can be configured for the production of reinforcement steel mesh, for example.
Furthermore, it can be practical if the unreeling apparatus has at least three deflection rollers, wherein the rotation axles of the deflection rollers are disposed on an arc, so that the wire material is guided around the unreeling apparatus in arc shape. It is advantageous, in this regard, that an implementable tensile force for unreeling the wire material can be increased by means of this measure, since the looping angle of the wire material around the unreeling apparatus can be increased.
Furthermore, it can be provided that the unreeling apparatus is coupled with a servomotor. Drive of the unreeling apparatus with a servomotor brings with it the advantage that the length of wire material to be unreeled can be predetermined or measured with great precision.
Furthermore, it can be provided that the unreeling apparatus is movably mounted on the production system. It is advantageous, in this regard, that the unreeling apparatus can be adapted to the current winding status of the wire reel by means of this measure. In particular, it can be provided that the unreeling apparatus is laterally displaceable. Furthermore, it can be provided that the unreeling apparatus can be adapted to different unreeling diameters of the wire reel. For this purpose, it can be provided that the unreeling apparatus is axially displaceable with reference to its longitudinal expanse, or is mounted on the production system so as to pivot, with reference to its longitudinal expanse.
According to a special embodiment, it is possible that a guide element is disposed on the unreeling apparatus, on a side of the unreeling apparatus that faces the accommodation apparatus.

Also, the position information selected in the description, such as top, bottom, at the side, etc., for example, refer to the figure being directly described and shown, and this position information must be applied appropriately to the new position if a change in position occurs.
FIG. 1 shows a schematic representation of a first exemplary embodiment of a production system 1. The production system 1 is configured for processing a wire material 3 that is wound to form a wire reel 2.
The production system 1 comprises an accommodation apparatus 4 for accommodating the wire reel 2. Furthermore, an unreeling apparatus 5 is configured, by means of which the wire material 3 wound onto the wire reel 2 can be pulled off. The unreeling apparatus 5 comprises a first deflection roller 6 and a second deflection roller 7, between which a conveying means 8 is tensioned. Subsequently in the figure description, the unreeling apparatus 5 will be described in more detail with regard to FIG. 2.
Furthermore, it is provided that the production system 1 comprises a processing apparatus 10, which serves for further treatment of the unrolled wire material 3. The processing apparatus 10 can be configured as a straightening system 11, for example, and can thereby serve for straightening of the wire material 3.
In further alternative embodiments, not shown, the processing apparatus 10 can be configured as a cut-to-length apparatus, for example, which serves to cut the wire material 3 to length.
In FIG. 2, a further embodiment of the unreeling apparatus 5 is shown, which can be independent, wherein once again, the same reference symbols and component designations as in the preceding FIG. 1 are used for the same parts. In order to avoid unnecessary repetition, reference is made to the detailed description in the preceding FIG. 1, i.e. this is pointed out.
To pull the wire material 3 off from the wire reel 2, it is provided that an outer surface 12 of the conveying means 8 stands in contact with a surface 13 of the wire material 3, and that the wire material 3 is moved by the conveying means 8. In particular, it is provided that the wire material 3 is transported along with the advancing movement of the conveying means 8 by means of the friction that is in effect between the outer surface 12 of the conveying means 8 and the surface 13 of the wire material 3, preferably without any slip.
FIG. 3 shows an exemplary embodiment of the conveying means 8, with the wire material 3 disposed on it, in a cross-sectional representation.
As is evident from FIG. 3, the conveying means 8 can preferably have a rectangular cross-sectional shape. In an alternative embodiment, however, it can also be provided that the conveying means 8 has a round or also some other cross-sectional shape. The conveying means 8 can be configured in the form of a conveyor belt 9, for example. Alternatively to this, it is conceivable that the conveying means 8 is configured in the form of a chain, for example. In yet another embodiment variant, it is conceivable that the conveying means 8 is configured in the form of a toothed belt, for example.
As is evident from looking at FIGS. 2 and 3 together, it can be provided that the wire material 3 lies against the outer surface 12 of the conveying means 8. Lying opposite the outer surface 12, an inner surface 14 of the conveying means 8 is provided, which surface can be guided on a support unit 15 of the unreeling apparatus 5.
In order to achieve the best possible adhesion of the conveying means 8 to the surface 13 of the wire material 3, it is provided that permanent magnets 16 are disposed on the conveying means 8 or within the conveying means 8, by means of which magnets the conveying means 8 is pressed against the wire material 3.
In order to further increase the friction force between wire material 3 and conveying means 8, it can be provided that the outer surface 12 has a specific surface roughness. Furthermore, it can be provided that the outer surface 12 has a coating to be able to increase the friction coefficient or the wear resistance of the conveying means 8. Such a coating can be a special rubber material or another plastic material, for example.
Furthermore, it is conceivable that the conveying means has a core material 17 that serves to absorb the tensile forces in the conveying means 8. The core material 17 can be formed as a woven textile, by means of plastic fibers, by means of steel fibers, or in some other way, for example.
The conveying means 8 is driven by a drive unit 18, which can be configured, in particular, as a servomotor 19. The drive unit 18 can be coupled either with the first deflection roller 6 or the second deflection roller 7.
A drive unit 18, which is configured as a servomotor 19, has the advantage that the conveying means 8 and thereby the wire material 3 can be positioned precisely by means of the unreeling apparatus 5.
Alternatively to the servomotor 19, a stepper motor can also be used as a drive unit 18, for example, wherein when using a stepper motor, an additional sensor 20 is required that detects the current position of the conveying means 8.
Such a sensor 20 can be configured in the form of an angle of rotation sensor, for example, which can be coupled with the first deflection roller 6 or the second deflection roller 7 of the unreeling apparatus 5. Furthermore, the sensor 20 can be configured as an incremental sensor, for example, which reads an incremental strip disposed on the conveying means 8.
The conveying means 8 can consist, for the most part, of a plastic material, in particular of a rubber-like material.
As indicated schematically, it can furthermore be provided that the inner surface 14 of the conveying means 8 has a gearing 21 that can correspond with a counter-gearing 22 of one of the deflection rollers 6, 7. By means of such a gearing, the positioning precision of the unreeling apparatus 5 can be increased.
As is evident from FIG. 2, it can furthermore be provided that a photoelectric barrier 23 or a detection means is disposed in the region of the unreeling apparatus 5, by means of which an end surface 24 of the wire material 3 can be detected. As a result, the beginning of the wire material 3 can be determined when a new wire material 3 is laid in. Furthermore, it can be provided that the photoelectric barrier 23 has an expanded functionality as a detection means, and serves to detect or determine the wire material 3, for example. In particular, it can be provided that the diameter 25 or the type of the wire material 3 can be detected by means of the photoelectric barrier 23.
As is evident from FIG. 3, it can be provided that a thickness 26 of the permanent magnet 16 is selected to be less than the thickness 27 of the conveying means 8. As a result, it can be achieved that the permanent magnet 16 is accommodated in the conveying means 8 with a covering 28. In particular, in this way the result can be achieved that the permanent magnet 16 cannot fall out of the conveying means 8.
Furthermore, it can be provided that a width 29 of the permanent magnet 16 is selected to be less than a width 30 of the conveying means 8.
In FIG. 4, a further embodiment of the conveying means 8, which can be independent, is shown, wherein once again, the same reference symbols and component designations as in the preceding FIG. 3 are used for the same parts. In order to avoid unnecessary repetition, reference is made to the detailed description in the preceding FIG. 3, i.e. this is pointed out.
As is evident from FIG. 4, it can be provided that the permanent magnet 16 projects out of the conveying means 8 and thereby the outer surface 12 on which the wire material 3 lies is configured directly on the permanent magnet 16. In the case of such an embodiment variant, the thickness 27 of the conveying means 8 can be kept low in comparison with the thickness 26 of the permanent magnet 16, and thereby the result can be achieved that the deflection roller and the drive roller can have the smallest possible diameter, since the flexibility of the conveying means 8 can be increased.
In FIG. 5, a further embodiment of the conveying means 8, which can be independent, is shown, wherein once again, the same reference symbols and component designations as in the preceding FIGS. 3 and 4 are used for the same parts. In order to avoid unnecessary repetition, reference is made to the detailed description in the preceding FIGS. 3 and 4, i.e. this is pointed out.
As is evident from FIG. 5, it can be provided that a groove-shaped depression 31 is configured, which is disposed on the outer surface 12 of the conveying means 8. The groove-shaped depression 31 extends over a longitudinal expanse 32 of the conveying means 8. Stated in other words, the groove-shaped depression 31 is disposed circumferentially on the conveying means 8.
As is evident from FIG. 4, it is preferably provided that a groove bottom 33 of the groove-shaped depression 31 has a rounding, so that the wire material 3 always lies at the deepest point of the groove bottom 33. As a result, it can be achieved that the contact point between wire material 3 and outer surface 12 of the conveying means 8 always lies at the same height even in the case of different wire materials 3 having different diameters 25.
In an alternative embodiment variant, not shown in any detail, it can also be provided that the groove-shaped depression 31 is configured in the form of a V-shaped groove.
In FIG. 6, a schematic longitudinal section of a further embodiment of the conveying means 8, which can also be independent, is shown, wherein once again, the same reference symbols and component designations as in the preceding FIGS. 1 to 5 are used for the same parts. In order to avoid unnecessary repetition, reference is made to the detailed description in the preceding FIGS. 1 to 5, i.e. this is pointed out.
As is evident from FIG. 6, it can be provided that the conveying means 8 has recesses 34, which extend in the direction of the inner surface 14, proceeding from the outer surface 12 of the conveying means 8. The recesses 34 have a recess depth 35 that is less than the thickness 27 of the conveying means 8. By means of the recesses 34, the result can be achieved that the conveying means 8 can be deflected about a deflection roller having only a slight diameter.
The individual permanent magnets 16 can be accommodated between the recesses 34 in the conveying means 8.
In FIG. 7, a schematic longitudinal section of a further embodiment of the conveying means 8, which can also be independent, is shown, wherein once again, the same reference symbols and component designations as in the preceding FIGS. 1 to 6 are used for the same parts. In order to avoid unnecessary repetition, reference is made to the detailed description in the preceding FIGS. 1 to 6, i.e. this is pointed out.
As is evident from FIG. 7, it can be provided that the recesses 34 are configured directly between the individual permanent magnets 16.
In FIG. 8, a further embodiment of the production system 1, which can also be independent, is shown, wherein once again, the same reference symbols and component designations as in the preceding FIGS. 1 to 7 are used for the same parts. In order to avoid unnecessary repetition, reference is made to the detailed description in the preceding FIGS. 1 to 7, i.e. this is pointed out.
As is furthermore evident from FIG. 8, it can be provided that the wire reel 2 is disposed on a raw material roller 36. The raw material roller 36 can serve for this purpose and to be able to transport the wire reel 2 more easily, i.e. to be able to simply wind the wire reel 2 up on the raw material roller 36.
Furthermore, a braking mechanism 37 can be provided, by means of which the raw material roller 36 or the wire reel 2 can be braked. In this way, undesirable unreeling of the wire reel 2 can be prevented to the greatest possible extent. Furthermore, by means of the tightening of the wire material 3, it can be prevented that loops form on the wire reel 2, in which the wire material 3 becomes jammed.
Furthermore, it can be provided that the wire material 3 is guided to the processing apparatus 10 in an arc 38. This brings with it the advantage that the arc 38 serves as a buffer. In this regard, the processing apparatus 10 can have great acceleration values during intake of the wire material 3, wherein the wire material 3 does not have to be unwound from the wire reel 2 at the same speed.
Furthermore, it can be provided that at least a third deflection roller 39 is disposed between the first deflection roller 6 and the second deflection roller 7. The rotation axles 40 of the three deflection rollers 6, 7, 39 can be arranged in an arc 41 relative to one another, as is evident in this exemplary embodiment, so that the wire material 3 is guided around the unreeling apparatus 5 in arc shape. The more additional deflection rollers 39 are disposed between the first deflection roller 6 and the second deflection roller 7, the more the progression of the conveying means 8 at the contact surface can come close to a continuously running arc. By means of this configuration of the unreeling apparatus 5, the result can be achieved that the looping angle at the unreeling apparatus 5 can be increased, and thereby the friction force between conveying means 8 and wire material 3 can be increased.
Furthermore, it can be provided that a guide element 43 is disposed on the unreeling apparatus 5, on a side 42 of the unreeling apparatus 5 that faces the accommodation apparatus 4. The guide element 43 can be configured in the form of a ring-like element, for example, which has a central bore through which the wire material 3 is passed, and by means of which guidance or centering of the wire material 3 can be achieved.
Furthermore, it can be provided that the unreeling apparatus 5 is guided on a guide rail 44, by means of which the unreeling apparatus 5 can be displaced in a vertical direction. As a result, the position of the unreeling apparatus 5 can be adapted to different diameters of the wire reel 2. In addition, it can be provided that the unreeling apparatus 5 is guided to be displaceable in a horizontal direction, in order to be able to displace the unreeling apparatus 5 with reference to the width of the wire reel 2, and thereby for it to be able to be adapted with reference to the current winding position of the wire material 3.
Furthermore, it can be provided that the unreeling apparatus 5 can be mounted so as to pivot. This can be particularly advantageous so as to be able to adapt the unreeling apparatus 5 to different positions or unreeling states of the arc 38.
In FIG. 9, a further embodiment of the production system 1, which can also be independent, is shown, wherein once again, the same reference symbols and component designations as in the preceding FIGS. 1 to 8 are used for the same parts. In order to avoid unnecessary repetition, reference is made to the detailed description in the preceding FIGS. 1 to 8, i.e. this is pointed out.
As is evident from FIG. 9, it can be provided that the unreeling apparatus 5 is positioned relative to the wire reel 2 in such a manner that the wire material 3 makes a transition from the wire reel 2 into the unreeling apparatus 5 in a continuous arc. This can be advantageous, in particular, if the wire reel 2 is driven and runs synchronously with the unreeling apparatus 5, to the greatest possible extent. In this regard, the continuous arc can serve as a buffer between wire reel 2 and unreeling apparatus 5.
As is evident from FIG. 9, it can be provided that a cut-to-length apparatus 45, which cuts the wire material 3 to form raw material rods 46, is connected with the processing apparatus 10. The raw material rods 46 can subsequently be transported vertically downward, using a vertical conveyor 47, so that they can subsequently be transported to a further vertical conveyor 47 using one or more horizontal belts 48. From this further vertical conveyor 47, the raw material rods 46 can be supplied to a rod cut-to-length apparatus 49, in which the raw material rods 46 can be shortened further.
In FIG. 10, a further embodiment of the production system 1, which can also be independent, is shown, wherein once again, the same reference symbols and component designations as in the preceding FIGS. 1 to 9 are used for the same parts. In order to avoid unnecessary repetition, reference is made to the detailed description in the preceding FIGS. 1 to 9, i.e. this is pointed out.
As is evident from FIG. 10, it can be provided that the unreeling apparatus 5 is disposed to follow the wire reel 2 directly, so that it takes up as little space as possible. The wire material 3 can form an arc before it is introduced into the processing apparatus 10, which arc, as a buffer, can balance out different unreeling speeds between unreeling apparatus 5 and wire reel 2.
In FIG. 11, a further embodiment of the production system 1, which can also be independent, is shown, wherein once again, the same reference symbols and component designations as in the preceding FIGS. 1 to 10 are used for the same parts. In order to avoid unnecessary repetition, reference is made to the detailed description in the preceding FIGS. 1 to 10, i.e. this is pointed out.
As is evident from FIG. 11, it can be provided that a lever 50 is disposed in the region of the wire reel 2, which lever is spring-loaded and deflects the wire material 3 by way of a deflection roller disposed at the end of the lever. A buffer for the wire material 3 can be created by means of a pivoting movement of the lever 50, which buffer can balance out different unreeling speeds between unreeling apparatus 5 and wire reel 2.
The exemplary embodiments show possible embodiment variants, wherein it is noted at this point that the invention is not restricted to the specifically shown embodiments variants of the same, but rather also various combinations of the individual embodiment variants with one another are possible, and this variation possibility lies within the ability of a person skilled in the art of this technical field, on the basis of the teaching for technical action provided by the present invention.
The scope of protection is determined by the claims. However, the description and the drawings should be referred to for an interpretation of the claims. Individual characteristics or combinations of characteristics from the different exemplary embodiments that are shown and described can represent independent inventive solutions in and of themselves. The task underling the independent inventive solutions can be derived from the description.
All information regarding value ranges in the present description should be understood to mean that these include any and all partial ranges of them; for example, the information 1 to 10 should be understood to mean that all partial ranges, proceeding from the lower limit 1 and the upper limit 10, i.e. all partial ranges, beginning with a lower limit of 1 or more and ending with an upper limit of 10 or less, for example 1 to 1.7, or 3.2 to 8.1, or 5.5 to 10, are included.
For the sake of good order, it should be pointed out, in conclusion, that for a better understanding of the structure, elements were shown not to scale and/or enlarged and/or reduced in size, in part.
