Description

The invention relates to a cooling bed with a transverse conveyor and means for turning longitudinally extending workpieces. Likewise, the invention relates to a method for turning on a cooling bed with a transverse conveyor located, extending longitudinally workpieces.

Such cooling beds or turning process are for example from the DE 26 02 607 C2 known and used in particular the cooling of longitudinally extending rolling, which is performed with a component perpendicular to its longitudinal direction by means of the cross conveyor on the cooling bed. Here, an emphasis of this publication is that different types of workpieces, such as rods or rods in particular with different cross sections or different diameters cooled and turned here. By turning a changing contact point of the workpieces can be realized with the cooling bed, which requires a more even cooling and thus a lower risk of building up tensions. This ultimately also provides the opportunity to provide straighter profiles immediately. In this case, this procedure has proven to be an advantage, in particular for profiles made of brass alloys.

It is an object of the present invention to provide cooling beds or turning methods for turning on a cooling bed with a transverse conveyor befindlicher, extending longitudinally workpieces, in which different types of workpieces can be turned in a structurally simple manner.

The object of the invention is achieved by cooling beds or turning method for turning on a cooling bed with a transverse conveyor located, elongated workpieces with the features of the independent claims. Further, possibly also independent thereof, advantageous embodiments can be found in the subclaims and the following description.

Here, the invention proceeds from the basic knowledge that by separating the cross-conveying functionalities from the turning functionalities advantages with regard to the variability with which different types of workpieces can be moved are achieved This separation only seems to lead to structurally more complex structures, since it has been found that the separation of these functionalities in specialized aggregates can be implemented, which can ultimately prove to be structurally simpler.

Thus, on a cooling bed with a transverse conveyor and means for turning longitudinally extending workpieces different types of work can be turned in a structurally simple way, when it is characterized by the cooling bed, that the turning means are controlled independently of the cross conveyor. Although this initially apparently no structural simplification, since a separate control must be provided for the turning means. However, this separate control allows these - and possibly also the turning means as such - can be specialized on the turning functionality.

Also, different types of work can be turned in a structurally simple manner on a cooling bed with cross conveyor and with means for turning longitudinally extending workpieces when the cooling bed is characterized in that the turning means two contact the workpiece to be turned at least in one operating position during turning Include upcoming turning facilities, which are independent of the cross conveyor displaced. At least in this operating position, the workpiece can then be held and turned by the two turning systems to which it bears, which can be done independently of the transverse conveyor.

Likewise, located on a cooling bed with a cross conveyor, longitudinally extending workpieces different types of workpieces can be turned in a structurally simple manner, if the turning process is characterized in that the workpieces lifted off the cross conveyor and turned on this again stored. This, too, requires a turning process that is independent of the lateral conveyance, which only seems to contribute to a complexity. In a suitable embodiment of the method, however, requires the separation between cross-conveying and turning a structural simplification, since both processes are each carried out highly specialized and therefore can be adapted to different types of work easier.

The present invention is suitable for any type of longitudinally extending workpieces, the advantages in particular in longitudinally extending rolling, which is to be cooled accordingly, can be used. Here are the advantages, especially in profiles made of aluminum or steel alloys, with corresponding advantages can obviously be used with other materials. If appropriate Embodiment of the turning means can be used in particular controlled rectangular or asymmetrical cross sections, with appropriate adjustments in the cross conveyors in itself usually do not seem necessary, as in this rule, if not inappropriate measures were taken, are extremely flexible anyway.

As already explained above, it is advantageous if the turning means are controllable independently of the transverse conveyor, which in particular makes a serious difference to the DE 26 02 607 C2 represents, after which the turning means are integrated in the cross conveyor and thus an adaptation to different workpiece type is effected in that the movement of the cross conveyor must be changed, which on the one hand structurally relatively complex and on the other hand also sets certain limits with respect to the diversity of the workpiece types.

In a suitable embodiment, the independent control of the turning means, that the turning means are structurally independent of the cross conveyor configured by, for example, in intermediate spaces, which leaves the cross conveyor, are placed. This allows, with a suitable embodiment of the present invention, that the turning means are possibly also on cooling beds, which previously provided no turning ability, be installed.

An independent controllability can be realized in particular by the fact that the turning means comprise a drive motor independent of the transverse conveyor. It is understood that as the drive motor, any energy converter which converts other types of energy into mechanical energy for driving the turning means can be used. In particular, hydraulic or electric motors seem to be suitable in this respect, since correspondingly energy carriers are provided on such cooling beds, inter alia for driving the transverse conveyor. Of course, depending on the specific implementation, pneumatic or hydrostatic drives can also be used.

The two turning systems already explained above, which come into contact with the respective workpieces to be turned at least in one operating position and are displaceable independently of the transverse conveyor, can ultimately be provided on each device which is displaceable independently of the transverse conveyor for a turning movement , Thus, the two turning systems can be provided, for example, on a pair of pliers or on a gripper or on similar structures, wherein ultimately it is not absolutely necessary for the two turning systems to clamp the workpiece in such a way or are braced with the workpiece such that the workpiece is rigidly or firmly connected to the corresponding assembly. Often it may be sufficient if the workpiece rests in the corresponding operating position only at the two turning equipment.

Accordingly, it may be advantageous if the turning equipment grip the workpiece at least in the operating position during turning. Although this may be structurally relatively expensive, since gripping a corresponding movement of the turning systems to each other. On the other hand, this requires a particularly stable movement during turning, which is precisely manageable.

On the other hand, it is understood that it may be sufficient with a suitable arrangement of the turning systems, if they lead or wear the respective workpiece only in a suitable manner and are only in the workpiece leading or supporting manner in contact with the workpiece.

It may be advantageous if one of the two turning systems lifting and the other of the two turning systems are depositing effectively, since such a separation of the respective tasks of turning equipment and a corresponding specialization at least in the aforementioned operating position with appropriate implementation can lead to a considerable structural simplification.

For example, the turning systems can also be arranged rigidly relative to one another with a suitable arrangement and can be designed to be displaceable independently of the transverse conveyor. By turning or by a corresponding displacement of the two turning systems then a turning process can be carried out at the workpieces, wherein - possibly - the angle by which the turn can be made should turn out less than when the turning system grip the workpiece, because at larger turning angles and rigidly arranged turning systems from a certain turning angle the workpiece possibly performs uncontrolled movements. This disadvantage can - if necessary - be countered by several successive turning operations, which in any case seems to be advantageous in view of the objective of enabling the most uniform possible cooling process.

In particular, the two turning systems can be provided on a common assembly, which in particular can also be formed in one piece, which is structurally particularly simple.

Preferably, the two turning systems are provided on a toggle lever, which allows a particularly simple structural implementation. It is particularly advantageous if the two turning systems are provided on different levers of the toggle lever. In this way, in particular, a different functionality, such as the above-explained lifting effectiveness of a turning plant and the depositing efficiency of the other turning plant, can be implemented in a structurally simple manner.

In this context, it should be emphasized that the two turning systems or assemblies that provide the turning equipment, such as the toggle lever or its lever, for other purposes, such as a Vorpositionierung by the cross conveyor the workpieces against the corresponding turning equipment or Module promotes, can be used.

In particular, the lever arranged in the turning direction of the toggle lever can be designed shorter than the counter to the turning direction arranged lever of the toggle lever. In this case, the lever arranged opposite to the turning direction can then lift, whereby, due to its relatively long configuration, rather diverse workpieces, in particular also workpieces with relatively large diameters, can lift. In the direction of turning arranged lever of the toggle one of the kindly long design is not absolutely necessary, since this is preferably only off - and possibly even prepositioned - is used, which is easily possible even with a slightly shorter design.

For the turning process, the corresponding components of the turning means are preferably designed to be rotatable, since rotations per se can be implemented in a structurally particularly simple manner. In particular, the turning systems can be provided on such rotatable assemblies, wherein - in a suitable embodiment - a further movement of the modules with respect to the cross conveyor or the remaining cooling bed preferably can not be provided, which is structurally even easier to implement.

Accordingly, it is advantageous if the toggle lever is rotatable, wherein the rotation is preferably provided in the knee of the toggle lever, so that in particular a corresponding axis of rotation there can support the toggle.

Preferably, the toggle lever or the assemblies of the turning means are rotatable by 360 °, which in itself can ensure a more uniform movement, if a suitable vote with the cross conveyor takes place, or, if appropriate Design of the overall arrangement, an operating position allows in which the turning means do not affect the movement of the workpieces on the cross conveyor, so that it can be operated in a conventional manner.

In principle, it is sufficient if the angle of rotation, about which the corresponding assemblies are rotatable, corresponds to the desired turning angle about which the workpieces are to be turned by the respective turning means. However, the flexibility of the turning means can be increased if the rotatability of the assemblies, such as the toggle lever, the turning angle is increased compared. This makes it possible, for example, to swivel these assemblies, in particular the toggle lever, out of the conveying area of the transverse conveyor, so that the arrangement can also be operated without a turning possibility.

Due to the rotational movement, lifting of the workpieces from the cross conveyor and depositing the same with simultaneous turns can be implemented in a structurally simple manner, this movement generally indicating that the workpieces are additionally conveyed transversely with the turn. Since ultimately a cross conveyor is already provided for a promotion on the cooling bed, such a coupling of the turning movement with a cross-conveying movement is not critical per se. It is immediately understandable that the transverse conveying, which may be caused by the turning means, usually involves only a fraction of the conveying distance provided by the transverse conveyor.

Preferably, the transverse conveyor itself does not comprise any turning means, although possibly the turning means act to promote transverse movement. This makes it possible in particular to design the cross conveyor in a conventional manner or to resort to conventional cross conveyor, which is particularly advantageous for retrofitting cooling beds.

In particular, beam conveyors or lifting beam conveyors are suitable as cross conveyors whose use is well known and proven in connection with cooling beds.

In this case, in particular, the turning means or any turning units of the turning means may be provided in the conveyor region of the transverse conveyor, which may happen, for example, in bar conveyors or lifting beam conveyors, for example simply by arranging the turning units or turning means in spaces between the bars.

In particular, the turning means may comprise a plurality of turning units arranged in the conveying area of the transverse conveyor. In this case, each of the turning units can each comprise two turning systems, which are displaceable independently of the transverse conveyor or can be controlled independently of the transverse conveyor.

Depending on the specific arrangement, the turning units can serve different purposes.

Thus, for example, turning units arranged in the conveying direction on different conveying positions can be used to successively carry out turning processes, so that the workpieces can be turned in the desired manner in each case in several steps.

It is also conceivable to arrange at least two turning units on a conveying position of the transverse conveyor, so that the turning unit can act on a single workpiece at the same time turning, which is particularly advantageous for long workpieces to perform the turn reliably.

Preferably, the drive of the turning units is synchronized, even if they are controlled independently of the transverse conveyor. On the one hand, the synchronization can preferably take place in relation to the transverse conveyor, so that the movements of the workpieces can be coordinated in a suitable manner. Also, the turning units can be driven synchronized with each other, so that corresponding turning processes are also performed simultaneously, which is particularly advantageous if the synchronously driven turning units are arranged on a conveying position of the transverse conveyor, so that respectively turned by two turning units workpiece simultaneously from the turning units or . is accelerated or braked the Wendemitteln.

It is understood that the features of the solutions described above or in the claims can optionally also be combined in order to implement the advantages in a cumulative manner.

Further advantages, objects and features of the present invention will be explained with reference to the following description of exemplary embodiments, which are shown in particular in the appended drawing. In the drawing show:

FIG. 1

a cooling bed with a cross conveyor and means for turning longitudinally extending workpieces in supervision; and

FIG. 2

a turning unit of the cooling bed after FIG. 1 in a schematic side view and in various operating positions.

The cooling bed 10 shown in the figures comprises a cross conveyor 11 constructed as a beam conveyor 12, which has a plurality of beams 13 spaced parallel to one another by means of which workpieces 30 can be conveyed in a conveying direction 31 through a conveying region 32 in a manner known per se.

The workpieces 30 extend substantially perpendicular to the conveying direction 31 or perpendicular to the plane of the drawing FIG. 2 and, while being conveyed by the cross conveyor 11 in the conveying direction 31 through the conveying area 32, take different conveying positions 33, which are offset in the conveying direction 31 in parallel to each other. The exact position of the conveying position depends on the type of workpieces 30 and on the movement sequence of the cross conveyor 11.

At defined conveying positions 33 are, as in particular in FIG. 1 shown, turning units 26 are provided, which are arranged between the bars 13 left intervals.

In the present embodiment, each of the turning unit 26 comprises a toggle 24, which is rotatable about a knee 25 of the toggle lever 24 in a turning direction 39 and has a turning direction 39 arranged lever 22 and a counter to the turning direction 39 arranged lever 23.

The levers 22, 23 each have a turning device 21, wherein the turning system 21 of the counter to the turning direction 39 arranged lever 23 lifting and the turning system 21 of the arranged in turning direction lever 39 22 are depositing effective.

The turning units 26 and the turning systems 21 are therefore turning means 20, by means of which workpieces 30 can be targeted.

As a drive 40, each turning unit 26 has a drive wheel 44, which on the one hand can drive the knee lever 24 and on the other hand by a drive pinion 43 which is seated on a drive shaft 42 driven.

As in FIG. 1 schematically illustrated, a plurality of turning units 26 are each arranged on a conveying position 33 and share a common drive shaft 42 which is driven by a drive motor 41 respectively.

In this way, the turning units 26, which are arranged on a conveying position 33, can be driven synchronously.

It is understood that in different embodiments, for each turning unit 26, a separate drive motor may be provided. It is also conceivable that in different embodiments, the drive shafts 42 are driven by a common drive motor, which can be done for example via a toothed chains or gear connections between the drive shafts.

It is understood that in other embodiments, other drives 40 may be provided for the turning units 26, such as hydraulic, pneumatic or hydrostatic drives.

In the present embodiment, the toggle 24 are each rotatable by 360 ° in turning direction 39. This allows on the one hand a turning operation by the toggle lever 24 of the in FIG. 2a represented position over in FIG. 2b represented position in the in Figure 2c shown position is spent. On the other hand, the toggle lever 24 in the operating position, which in Figure 2d is shown, so that workpieces 30 can be promoted to the Wendemitteln 20 over by means of the cross conveyor 11.

For a new turning operation, the respective toggle 24 are back to the starting position of FIG. 2a spent.

In the in FIG. 2a illustrated position, the toggle lever 24 with its lever 22 also serve as an abutment against which the workpieces 30 are conveyed by the cross conveyor 11 so that they are to be found in a reliable position when a turning operation is to be initiated.

It is understood that in different embodiments, the toggle may possibly also be rotatable against the turning direction 39. It is also conceivable that in different embodiments, a rotation through 360 ° can not be provided, which may then be replaced if necessary by a corresponding return movement.

It is also conceivable that instead of the toggle lever 24 other lever arrangements, for example arrangements with even more levers, are provided to be able to perform somewhat different turning operations, for example turning operations in which a lever arrangement does not have to pivot through a full 360 °.

It is also immediately conceivable that, instead of the lever arrangement, grippers or the like perform a corresponding turning operation.

Because the knee 25 of the toggle lever 24 and thus the axis of rotation of the toggle lever 24 is arranged below the respective workpieces 30, the workpiece 30 is raised due to the rotational movement of the toggle lever 24, in particular in FIG FIG. 2b seen. In the case of transverse conveyor 11 or bar 13, which is invariable in terms of height, this means that the workpieces 30 are each lifted off the cross conveyor 11 during turning and are turned on the latter again. Naturally, the workpieces 30 are also conveyed a little laterally, ie in the conveying direction 31.

In the in FIG. 2b shown operating position 29 of the turning means 20 are, as immediately apparent, both turning equipment 21 to the respective workpiece 30 and thus are in contact with this. This is at the in FIGS. 2a, c and d Operating positions shown not the case, since there at least one of the levers 22, 23 of the bell crank 24 can be found below the conveying region 32 of the cross conveyor 11. In the operating position after FIG. 2a This serves a relief of the turning means 20, while this in the in Figure 2c shown operating position serves to allow a smooth placement of the workpieces 30 on the cross conveyor 11. As already explained above, this serves at the in Figure 2d shown operating position to remove the turning means 20 from the conveying region 32 of the cross conveyor 11.

In the present embodiment, the individual turning units 26 with the drive shafts 42 and the drive motors 41 are ultimately stationary but independently of the building blocks of the transverse conveyor 11, they are mounted fixed to the building. In different embodiments, it is also conceivable to provide the turning means 20 or the individual turning units 26 on assemblies of the transverse conveyor 11, such as on fixed beams 13 or on a frame or even on moving beams 13, this being at a separation of the turning function of the cross conveyor function per se does not change anything. It is also understood that - depending on the concrete implementation - the drives of the cross conveyor and the turning means can be synchronized.
