Definitions

  • the invention relates to a device for compensating variations in tension and/or for adjusting the tensile stress on a conveyed flexible metal material strand, in particular a metal strip having at least one movable dancer roll which can be wound around by the material strand.
  • a dancer roll arrangement comprises a roll which is integrated into the strip flow of a strip treatment plant and can be acted on by a certain force, this roll forming a loop in the strip, the length of which loop changes with the position of the roll.
  • FIGS. 1 to 5 typical dancer roll arrangements known from the prior art are illustrated.
  • the invention is based on the object of specifying a device for compensating variations in tension and/or for adjusting the tensile stress on a conveyed flexible metal material strand, in particular a metal strip, which is very simply constructed and can consequently be integrated with little effort into existing treatment plants for metal material strands, in particular material strips.
  • the device is to allow even short-term variations in tension to be compensated in thick and heavy material strands as well as thin and sensitive material strands, wherein a change in the material strands during continuous operation with a corresponding adjustment to the tensile stress is also to be possible without difficulty.
  • the object is achieved according to the invention with a device according to the preamble of claim 1 , in that the at least one dancer roll can be displaced along a path inclinable to the perpendicular, wherein the inclination angle of the path can be adjusted by means of an adjustment unit.
  • the present invention is based on the notion that by means of a suitable inclination of the direction of movement of the dancer roll to the perpendicular, and thus to the weight force vector of the dancer roll, the strip tension can be precisely adjusted without additional weights increasing the inert mass of the arrangement and without actuators.
  • metal material strand is understood to be wire-shaped or strip-shaped material, strips for transporting goods of different types and also metal ropes, wires and the like.
  • the full weight force of the dancer roll and of its bearing can, for example in the case of thick, heavy material strands, be exploited to produce a sufficient strand tension (strip tension), namely by reducing the inclination angle to zero, so that the dancer roll can be displaced in the vertical direction.
  • the inclination angle can be correspondingly increased up to nearly 90°, so that the weight force of the dancer roll and of its bearing has practically no effect any more on the strand tension and this is accordingly minimal.
  • the tensile force effective in each case can be determined from the weight force of the dancer roll and of its bearing by a simple trigonometrical equation. The equation corresponds to the downhill-slope force on an inclined plane and is calculated as
  • the adjustment unit is designed to be controllable for adjusting the inclination angle of the path, i.e. a change in the inclination can be triggered by a corresponding control command during automated operation of a treatment plant for the metal material strands, in particular of a strip treatment plant.
  • a change in the material strand occurs during continuous operation of the treatment plant, wherein the ends of both strands are attached to one another.
  • the dancer roll is arranged between two deflector rolls, so that in operation the flexible metal material strand together with the dancer roll forms a strip loop.
  • the path, inclinable to the perpendicular is linear.
  • a strictly linearly designed path for example a linear guide
  • the inclination angle set to the perpendicular is precisely maintained irrespective of the current position of the dancer roll in the dancer movement, so that the tensile force continuously exerted on the flexible material strand exactly corresponds to the value preset by the choice of the inclination angle of the path.
  • this can be accomplished, for example, by the bearing of the dancer roll being essentially frictionlessly guided on a linear guide.
  • Linear roller guides are particularly suitable for this purpose.
  • linear guides can also be employed as “linear guides”, for example roll guides and rail guides of all kinds as well as slide guides or air cushion guides or magnetic guides.
  • the shaft of the dancer roll can be guided in a linear slot or in a gap between two carriers aligned parallel to one another.
  • the adjustment unit can comprise an electromechanical drive, in particular a spindle drive, or a regulating element, in particular a hydraulically or pneumatically operating cylinder, so that the linear guide can be pivoted about a pivot point to adjust the inclination angle of the path.
  • a pivoting mechanism can be easily produced in terms of construction and, in addition, can be integrated into a general machine control system without difficulty.
  • the path, inclinable to the perpendicular can be curved, in particular curved in the shape of an arc of a circle, wherein the radius of curvature chosen must be large against the deflection of the dancer roll along the curved path.
  • a suitable ratio between radius of curvature and dancer roll deflection is about ⁇ 3:1.
  • this variant can be put into effect by using a swing arm, on which the bearing of the dancer roll is guided, wherein the pivot point of the swing arm for its part can be displaced to adjust the inclination angle of the path on which the dancer roll can be displaced.
  • the adjustment unit can comprise an adjusting drive, so that the pivot point of the swing arm can be displaced along a linear essentially vertically aligned trajectory.
  • the adjustment unit can comprise an adjusting drive, the kinematics of which enable the pivot point of the swing arm, on the end of which the dancer roll is arranged, to be displaceable along a curved essentially vertically aligned trajectory.
  • This trajectory can be predetermined by a further swing arm on which the pivot point is pivotably mounted.
  • the at least one dancer roll When using the dancer roll to adjust the path tension with very heavy, flexible metal material strands, which require corresponding tensile forces, it can be advantageous for the at least one dancer roll to be displaced along the path, inclinable to the perpendicular, by the force effect of an actuator, in particular a hydraulic or pneumatic cylinder.
  • an actuator in particular a hydraulic or pneumatic cylinder.
  • This makes it possible to produce a further force, in addition to the force produced by the dancer roll itself, i.e. the downhill-slope force on the inclinable path, this further force increasing the path tension.
  • the actuator is employed at the time when an infinitesimal inclination angle is chosen, i.e. the full weight force acts on the flexible metal material strand.
  • a further aspect of the present invention relates to a treatment plant for sheet-shaped metal material having a device for adjusting the tensile stress and/or for compensating variations in tension in the sheet-shaped material according to any one of claims 1 to 10 .
  • the object mentioned at the outset using a method for operating a treatment plant for flexible metal material strands, in particular metal strips, having a device for adjusting the tensile stress and/or for compensating variations in tension in the material strand according to any one of claims 1 to 11 , is achieved, when changing the material strand during continuous operation of the treatment plant, by the tensile stress being altered by adjusting the inclination angle of the path by means of the adjustment unit.
  • the key advantage of the method is that because the tensile force can be altered during continuous operation of the treatment plant there is no risk of sensitive material strands being damaged as a result of tensile forces being too high, since even when changing from heavy, resistant material strands to lighter, sensitive strands during continuous operation an optimum strip tension can always be set.
  • FIG. 1 shows a prior art dancer roll arrangement for sheet-shaped material, having a linearly and vertically displaceable dancer roll, in schematic side view,
  • FIG. 2 shows a second prior art dancer roll arrangement for sheet-shaped material, having a dancer roll held on a horizontal swing arm,
  • FIG. 3 shows the dancer roll arrangement from FIG. 1 with a counterweight
  • FIG. 4 shows the dancer roll arrangement from FIG. 2 with a counterweight
  • FIG. 5 shows the dancer roll arrangement from FIG. 2 with an actuator
  • FIG. 6 shows a device for compensating variations in tension and for adjusting tensile stress on sheet-shaped material, having a dancer roll which can be displaced along a path inclinable to the perpendicular, according to a first embodiment
  • FIG. 7 shows the device from FIG. 6 with an actuator for increasing the tensile stress.
  • FIG. 8 shows a device for compensating variations in tension and for adjusting tensile stress on sheet-shaped material, in a second embodiment
  • FIG. 9 shows a treatment plant for metal strips having a device for adjusting the tensile stress and for compensating variations in tension according to FIG. 6 .
  • FIG. 1 shows a prior art dancer roll arrangement having a dancer roll 100 arranged between two deflector rolls 110 , 120 .
  • the strip M in the present case a metal strip, essentially horizontally guided in a strip treatment plant which is not illustrated in detail, is deflected downwards by the deflector roll 110 from the horizontal direction into the vertical direction, winds around the dancer roll 100 at a wrap angle in the region of 180° and then slightly inclined to the perpendicular is guided up to the second deflector roll 120 where it is deflected into the horizontal direction.
  • the dancer roll 100 can be displaced on a vertically aligned linear guide 130 , so that almost the entire weight force of the dancer roll 100 and of its bearing 110 a acts on the metal strip M. This can lead to impermissibly high strip tensions, particularly with thin and correspondingly sensitive metal strips.
  • FIG. 3 Another prior art solution is illustrated in FIG. 3 .
  • the weight force of the dancer roll 100 and of its bearing on the linear guide 130 acting on the metal strip M is compensated by a counter weight 140 , wherein the counter weight 140 can be chosen in such a way that the resulting tensile force acting on the metal strip M corresponds to the desired value.
  • the problem with this arrangement is that the inert mass of the dancer roll arrangement is correspondingly increased by the counterweight, so that with the compensating movements of the dancer roll 100 the inertia force both of the dancer roll 100 itself and of the counterweight 140 has to be overcome. This ultimately results in short-term variations in the strip tension, due to inertia, not being able to be satisfactorily compensated.
  • FIG. 4 shows the dancer roll arrangement from FIG. 2 , wherein here the swing arm 230 ′ is extended beyond the pivot point 240 and a weight 250 can be displaced along the swing arm 230 ′ in such a way that by means of a corresponding resisting moment it strengthens or weakens the tensile force exerted on the strip M by the weight force of the dancer roll.
  • FIG. 5 again shows the dancer roll arrangement from FIG. 2 , wherein here an actuator 260 in the form of a hydraulic or pneumatic cylinder acts on the swing arm 230 and consequently strengthens or also weakens the strip tensile force exerted on the strip M by the dancer roll 200 in a similar way to FIG. 4 .
  • an actuator 260 in the form of a hydraulic or pneumatic cylinder acts on the swing arm 230 and consequently strengthens or also weakens the strip tensile force exerted on the strip M by the dancer roll 200 in a similar way to FIG. 4 .
  • FIG. 6 a device for compensating variations in tension and for adjusting the tensile stress on sheet-shaped material, in the present case a metal strip M, having a dancer roll 2 which can be displaced along a path inclinable to the perpendicular, is illustrated in a first embodiment.
  • the metal strip M is, to that end, guided around a deflector roll 3 and thereafter forms with the dancer roll 2 a strip loop at a wrap angle in the region of 180°, before it is again deflected via a further roll 1 .
  • the deflection occurs in a direction inclined to the horizontal. It is, however, to be understood that a deflection into the horizontal or into another direction is equally possible.
  • the inclinable path of the device in FIG. 6 is in the present case designed as a linear guide 4 , on which the dancer roll can be essentially frictionlessly moved by means of a sub-frame 2 a on which the bearing blocks of the dancer roll are arranged.
  • the linear guide 4 can be pivoted by means of an adjustment unit (not illustrated in detail) comprising an electromechanical drive, in particular a spindle drive, about a pivot point X to adjust the inclination angle ⁇ .
  • G is the weight force of the dancer roll 2 and of its bearing and ⁇ is the inclination angle of the linear guide 4 .
  • the strip tension can hereby be precisely adjusted up to a maximum value, which is determined by the weight force of the dancer roll and of its bearing without using additional weights or regulating means. Short-term variations in the strip tension can be compensated in the usual way by supporting the dancer roll 2 essentially frictionlessly on the linear guide 4 .
  • the adjustment unit is designed to be controllable. This means that with a change in the strip thickness or width—here the ends of the strips of different thickness or width are attached to one another—the corresponding adjustment to the strip tension by changing the inclination of the linear guide 4 can be made during continuous operation of a strip treatment plant (cf. FIG. 9 ) prompted by a control command from the general machine control system.
  • the device from FIG. 6 is additionally provided with an actuator in the form of a pneumatic cylinder 5 .
  • an actuator in the form of a pneumatic cylinder 5 .
  • This is used when the strip tension produced by the full weight force of the dancer roll 2 and of its bearing is not sufficient, which, for example, can be the case when treating thick and very heavy metal strips.
  • the resulting strip tensile force is therefore calculated as
  • FIG. 8 a further device for compensating variations in tension and/or for adjusting tensile stress on a metal strip is illustrated in a second embodiment.
  • This device differs from the one in FIG. 6 , in that the dancer roll 2 cannot be moved frictionlessly along a linear unit but is suspended from a swing arm 6 , the chosen length of which is long compared with the adjustment area of the dancer roll 2 , so that the deflections of the dancer roll 2 when the device is in operation are in good approximation linear.
  • a suitable ratio between radius of curvature and dancer roll deflection is about ⁇ 3:1.
  • the inclination to the perpendicular of this virtually linearly deflectable dancer roll 2 can now in turn be adjusted, in order to exert the desired strip tension on the metal strip M.
  • the mounting of the swing arm i.e. its pivot point, can be moved along a predeterminable trajectory by means of an adjustment unit which is not illustrated.
  • FIG. 8 two differently adjusted inclination angles ⁇ , ⁇ ′ are illustrated.
  • the sub-frame 6 a of the swing arm 6 is moved into a lower position A which corresponds to a comparably small angle ⁇ 30°.
  • the sub-frame 6 a of the swing arm 6 is moved into an upper position B by means of an adjusting drive of the adjustment unit, which corresponds to an increased angle ⁇ ′ ⁇ 50°:
  • the movement of the sub-frame 6 a can be effected by an electromechanical drive as well as by a hydraulically or pneumatically operating cylinder (neither of which is illustrated in FIG. 8 ) of the adjustment unit.
  • FIG. 9 a treatment plant for metal strips having a device according to FIG. 6 is illustrated in FIG. 9 .
  • the metal strip M for example a copper or copper alloy strip
  • a furnace 12 for example an annealing furnace.
  • the strip M is deflected on the roll 3 and forms a loop with the dancer roll 2 , wherein the dancer roll 2 can be displaced, in the way described in connection with FIG. 6 , along a path inclinable to the perpendicular about the angle ⁇ by means of an adjustment unit which can be controlled by the general machine control system.
  • the metal strip is deflected again into the horizontal around a further roll 1 and finally wound up by a second roll 10 .
  • the current treatment plant for metal strips it is therefore possible to precisely preset the strip tension and alter it in a controlled way with modified operating parameters.
  • the general machine control system sends a corresponding control command to the adjustment unit to adjust the inclination angle ⁇ of the inclinable path, whereupon the adjustment unit correspondingly adjusts the inclination angle ⁇ , so that the dancer roll 2 always exerts an optimum strip tension on the metal strip M.
