Description

Field of the invention

The present invention is directed to a device for transferring metal strip from a reel to a further processing device, in particular to a belt process line. This belt process line can be formed, for example, by a pickling or rolling plant. The metal strip may be, for example, steel or stainless steel.

State of the art

Transfer devices for transporting a strip beginning of a metal collar to a further processing device are known in various designs. In many cases, after positioning and transferring the beginning of the tape through a pivoting guide table, the tape is pushed forward by the reel. The diameter-dependent strip initial curvature results in high frictional forces at the transfer point to the table with the result of loose turns in the bundle by the Abhaspelvortrieb. Furthermore, a blocking of the beginning of the tape by the existing initial tape curvature is likely, resulting in an increase in the initial tape curvature and thus usually no longer possible transfer results in the finishing plant.

The patent GB 988,334 describes an unwinding device for unwinding a metal strip from a reel which comprises a pivotable frame and a pair of rollers arranged on the frame. This frame is pivotable in the direction of the wound on the reel metal bands. Via a wing, the beginning of the tape can be lifted off the wound roll and be guided between the rolls of the roll pair. To unwind the tape, the frame is pivoted away from the reel and the wing lifted off the tape, so that the tape is guided only by the pair of rollers. A roller of the roller pair is driven and the second roller is rotatably connected via two gears with the first roller for conveying the tape.

A disadvantage of this device is the additionally required rotary drive, which takes up a considerable amount of space and costs. Furthermore, the translation of the first to the second role also takes the side of the system a large volume of construction. Furthermore, slippage between the two rollers and the transported belt is to be expected and thus with possible surface damage on the belt.

The object of the invention is to provide a compact and cost-transfer device, which can provide the band, in particular the beginning of the tape and / or the tape end, as flexible as possible a further processing device.

Preferably, damage to the metal band should be avoided during the transfer. The threading process of the beginning of the tape should also be possible as reliable as possible.

The 1 discloses a cross section through a plant 100 and in particular by a device 10 according to an embodiment of the invention. The attachment 100 includes a reel 30 on which a metal band 1 is wound up, as well as a transfer device 10 and a driver 40 which may be part of a further processing device. The driver 40 includes in this case preferably a pair of rollers 41 . 42 for receiving and conveying the metal strip 1 or the beginning A of the metal strip 1 , The metal band 1 can through the transfer device 10 from the reel 30 to the driver 40 be handed over. The transfer device 10 includes a hinged frame 3 , which is preferably, as shown, at its foot end about a pivot axis S pivotally. It may be the frame 3 on a foundation 20 be attached. The pivoting movement can be achieved by a swivel drive 19 which allows the frame 3 can pivot about the pivot axis S. The rotary actuator engages 19 preferably at a point Z of the frame 3 on, from the pivot axis S along the frame 3 considered spaced. The rotary actuator 19 may for example be formed by a piston-cylinder unit, but also be realized by other mechanical, pneumatic, hydraulic, electrical or electro-mechanical drives. The point Z of the drive 19 on the frame 3 if desired at other points of the frame 3 attack as shown.

Furthermore, the device comprises 10 at least two jaws 7 . 8th , which in each case for pinching the tape 1 to both sides of the band 1 can be created. Each of the jaws 7 . 8th is with a separate drive 11 . 12 fitted. The jaws 7 . 8th can be made for example of metal, especially steel. Furthermore, these may preferably have a rough or profiled surface to the friction between the jaws 7 . 8th and the metal band 1 to increase. Rubber or rubber coatings are also possible in principle. Preferably, the separate drives comprise 11 . 12 the jaws 7 . 8th a pair of jaws 7 . 8th also piston-cylinder units 11 . 12 , These can save space on the frame 3 to be ordered.

Furthermore, the device comprises 10 a pair of roles 5 . 6 for guiding the metal band 1 between both roles 5 . 6 of the role pair 5 . 6 , The roles 5 . 6 a role pair 5 . 6 are also separate from each other along the frame 3 movable or movable. However, this does not exclude having a jaw 7 for clamping the metal strip 1 from one side of the tape 1 and a roll located on the same hinge side 5 by the same drive 11 along the frame 3 are displaceable. The same applies to the second side of the tape 1 So for the role 6 and the jaw 8th , which in the embodiment together by the drive 12 for their displacement along the frame 3 are drivable. However, it is also generally possible that the roles 5 . 6 separate from the jaws 7 . 8th for their displacement along the frame 3 are driven. In the cross-sectional view of 1 are just a pair of jaws 7 . 8th and a pair of roles 5 . 6 shown. In the width direction of the metal strip 1 or transversely to the strip running direction, however, several such pairs may be arranged.

Preferably, in addition, a role 5 and a jaw 7 on a common carrier 13 or a cross member 13 arranged, wherein the cross member 13 by a drive 11 along the frame 3 is displaceable. This can be done respectively for the top and bottom of the metal band 1 be valid. So is preferably according to a lower cross member 14 provided on which a jaw 8th and a role 6 are fastened together and by a common drive 12 which is attached to the carrier 14 attacks, along the frame 3 can be moved.

Preferably, the rollers 5 . 6 of the roll pair 5 . 6 each biased or resiliently mounted, in particular such that they can deflect when contacting the tape. This feature will be described in more detail with reference to some of the following figures.

In the 1 a situation is shown in which the beginning A of the metal strip 1 already through the transfer device 10 is threaded or on a lower roll 6 the transfer device 10 is stored. To move the tape beginning A to this position, the device comprises 10 prefers a swiveling table 17 , with the help of the beginning of the tape A between the roles 5 . 6 and the jaws 7 . 8th can be passed. The movement of the beginning of the tape A or the tape 1 is preferred by the drive of the uncoiler 30 allows. The exact training of the table 17 may vary. Such tables 17 or scrapers are known in the art.

The 2 shows the same exemplary device as the 1 However, the frame is 3 about the pivot axis S by means of the drive 19 in the direction of the driver 40 pivoted. In this position, the frame extends 3 preferably in the vertical direction or parallel to the feed direction of the rollers 41 . 42 of the driver 40 , Here are the two roles 41 . 42 of the driver preferably one above the other, wherein the distance in the vertical direction is adjustable. For threading the beginning of the tape into the driver 40 become its roles 41 and 42 preferably lifted apart from each other in the vertical direction to a gap for the introduction of the beginning of the tape 1 to build. Between the in the 1 and 2 shown situations became the band 1 preferably by a drive of the uncoiler 30 settled. To pass the beginning of the tape A through the transfer device 10 to the driver 40 , the beginning of the tape A is preferably first through the jaws 7 . 8th trapped and following the tape 1 by Panning the frame 3 transported or handed over in the direction of the driver. The upper jaw contacts 7 the upper side (o) of the band 1 and the lower jaw the lower side (u) of the band 1 , During the pivoting process are preferred both jaws 7 . 8th (and also prefers the roles 5 . 6 ) along the frame 3 shifted, so that a (usually down) curved band end A above the lower driver role 42 between the two roles 41 . 42 of the driver 40 is introduced. The exact movement speed and distance of the jaws 7 . 8th or the roles 5 . 6 depends on the concrete, relative arrangement of the frame 3 , the reel 30 and the driver 40 , Further, also the band thickness or the curvature of the strip beginning A and the speed of the band v and the geometry of the frame 3 be taken into account.

The contacting of the band 1 through the jaws 7 . 8th is in a detailed view of the 3 shown in more detail. The situation depicted in this figure corresponds to that of 2 , where is the frame 2 is in a substantially vertical pivot position and the beginning of the tape A between the two rollers 41 and 42 of the driver 40 is introduced. The ribbon 1 is between the two jaws 7 . 8th sandwiched, with the upper jaw 7 the top (o) of the tape 1 contacted and the lower jaw 8th the bottom (u) of the band 1 contacted. The roles 5 . 6 the transfer device 10 contact, as in the 3 shown, preferably also the two sides of the tape 1 However, do not roll with the movement of the tape 1 because the band (stuck) between the jaws 7 . 8th is clamped, that is relative to the jaws ( 7 . 8th ) not moved.

The roles 5 . 6 are preferably arranged such that one of the two rollers 5 . 6 for contacting a side (o, u) of the metal strip 1 together with the jaw 7 . 8th for contacting the same side (o, u) of the metal strip 1 is displaceable, that is, by a common drive 11 . 12 is displaceable. This is made possible in the embodiment shown by the fact that the (upper) role 5 and the (upper) jaw 7 together on the (upper) carrier 13 are mounted. Likewise, the (lower) role 6 and the (lower) jaw 8th together on the (lower) carrier 14 mounted or arranged. Each of the carriers 13 . 14 is by a drive 11 . 12 , especially along the frame 3 , movable. Every drive 11 . 12 may be formed by one or more, in particular two, piston-cylinder units.

In particular, the roles 5 . 6 the transfer device 10 be stored biased. If one of the roles 5 . 6 the metal band is not contacted (see, for example 5 ), she protrudes over the jaws that are movable together with her 7 . 8th out (for example, substantially in a direction to reduce the distance between the rollers of the roller pair 5 . 6 or between the jaws of the jaw pair 7 . 8th ). Be the roles 5 . 6 from both sides of the metal band 1 on the metal band 1 move, they come into contact with one of the broad sides of the band 1 , Will no further force to move the rollers in the direction of the band 1 exercised, the tape becomes 1 between the two roles 5 . 6 kept or led. If the tape, for example, through the uncoiler 30 With settled, the roles become 5 . 6 through the moving band 1 set in rotation. Be, as in the case of 3 represented the roles 5 . 6 through the drives 11 . 12 continue in the direction of the band 1 move, spring in, so that the jaws 7 . 8th in contact with the two sides (o, u) of the metal strip 1 reach. In this state, the rollers rotate 5 . 6 not and the tape 1 is between the jaws 7 . 8th clamped or fixed. Preferably by jointly shifting the jaw pair 7 . 8th along the frame 3 and or by pivoting the frame 3 the tape and in particular the beginning of the tape A can be transferred.

The 4 again shows the same device as the previous figures. The swing frame 3 is in the same vertical position as in the 2 and 3 , Unlike in the 2 and 3 shown situation was the jaw pair 7 . 8th which is the band 1 clamped to the frame 3 through the drives 11 and 12 so along the frame 3 moved that the band beginning 1 on the lower roll 42 of the driver 40 is stored and the beginning of the tape 1 lying end already over the center axis of the lower driver role 42 is moved out.

In 5 which in turn is the plant already described 100 shows is the band 1 through the driver rolls 41 . 42 clamped and is furthered by this. The upper driver role contacts 41 the top of the band 1 and the bottom driver role 42 the bottom side of the band 1 , In this condition are the jaws 7 . 8th and also prefers the roles 5 . 6 from both broadsides of the tape 1 lifted so that the tape is free between the spaced rollers of the pair of rollers 5 . 6 and the jaws of the jaw pair 7 . 8th can move freely or without contact.

Will the band 1 , for example, like in 5 shown, unwound, remain on the reel 30 only a few turns of the metal band 1 , This creates the risk that the band end E uncontrollably detached from the coiler mandrel and strikes. On the one hand there is a risk for that Plant personnel and on the other hand, a risk for some significant damage to plant components by the end of the band end herumerschlagende To prevent such problems, the frame 3 the transfer device 10 turn in the direction of the reel 30 be panned. This situation is in the 6 shown schematically. The pivoting operation in this position is preferably carried out such that the rollers 5 . 6 and the jaws 7 . 8th do not touch the tape. Became the frame 3 through the drive 19 in the direction of the reel 30 Pivoting, the roles become 5 . 6 of the roller pair by the drives 11 . 12 each applied to the tape surface, so that the tape 1 through the roles 5 . 6 is guided (but not by the jaws 7 . 8th is trapped). Thus, the tape becomes 1 through the roles 5 . 6 when it is the reel 30 leaves.

Further, the tape end E by the transfer device 10 similar to the beginning of the tape A to the driver 40 be handed over. The corresponding transfer is exemplary in the 7 shown. This was the frame 3 turn in the direction of the driver 40 pivoted. However, the band end E is not preferred by the jaws 7 . 8th clamped but only by the to the tape 1 created roles 5 . 6 guided. Finally, the band end leaves E, preferably through the rollers 5 . 6 guided, the transfer device and moves between the two driver rollers 41 . 42 ,

In general, can be addressed to the lower hinge side engagable jaw 8th and role 6 be position-controlled. In this case, the position of these elements represents the controlled variable, wherein a recording of actual values can be carried out by position measuring devices, for example by encoders in the drive units for adjusting the position of the roller or jaw along the frame 3 ,

In particular, the position encoders in piston-cylinder units 11 be mounted. A setpoint or a reference variable can be determined by the geometry of the frame 3 , the abortionist 40 and the reel 30 or be given by their relative positions. Further, in this value, the pivotal position of the frame 3 received. If a control deviation is detected, by a control device (not shown), which acts as a controller, a signal (manipulated variable) for adjusting the drive unit 11 be issued, reducing the position of the role 6 or jaw 8th is corrected.

The to the upper side of the metal band 1 adjustable jaw 7 For example, it can be operated with force control, wherein the force is chosen such that when clamped by the jaw 7 a sufficient force is exerted for clamping. Such a desired force can be from the transported material and the material of the jaw 7 depend on and be selected accordingly by the skilled person. The actual on the tape 1 acting clamping force can by a force sensor, for example on the drive unit 11 be determined. In particular, this may be a force or pressure sensor in a piston-cylinder unit 11 be. If a measured force is compared with the desired value and results in a control deviation, then a control device can output a corresponding signal (manipulated variable) for correcting the pressure on the metal strip 1 output effective force (controlled variable).

Should the band 1 just between the roles 5 . 6 be guided, for example, for transporting the tape end E to the driver 40 so can the scheme for the upper roll 5 analogous to the case of clamping by means of the jaw 7 take place, wherein the desired force to guide the tape 1 through the upper roller 5 however lower is chosen. That is, in such a way that the role 5 Contact with the belt surface has, but not so far rebounded that the jaw 7 touches the tape surface. In other words, the desired force is on the roll 5 preferably smaller than the biasing force of the roller 5 , or the force that is needed to the role 5 einzufedern.

Alternatively, the upper roller 5 according to the thickness of the band 1 position-controlled pressed from above to the belt surface. For this purpose, preferably a thickness gauge is used, which is the thickness of the tape 1 supervised. Alternatively, however, could also be a predetermined thickness of the tape 1 be accepted.

The pivoting movement of the frame 3 can be force-controlled when clamping, for example, with a force measurement on the drive unit 19 can be made. Is the drive unit 19 as shown in the embodiment, a piston-cylinder unit 19 , so appropriate force or pressure transducer can be arranged in this unit. A corresponding desired force is chosen such that the frictional force of the jaws 7 . 8th for clamping the band 1 is not exceeded, causing the tape 1 through the jaws 7 . 8th would slip. On the other hand, however, the formation of loose turns on the metal collar on the reel should be preferred 30 be avoided, so that the target force is preferably chosen such that always a tensile force on the belt 1 affects, but no thrust, which the band 1 back in the direction of the reel 30 pushes.

Above all, the embodiments described above serve to better understand the invention and should not be understood as limiting. The scope of protection of This patent application results from the patent claims.

The features of the described embodiments can be combined or replaced with each other.

Furthermore, the features described can be adapted by the skilled person to existing circumstances or existing requirements.
