No. 07/620,105, 提交1990年11月30日，现在已经被废弃。本发明涉及到带钢卷取机卷绕和开卷薄带钢和金属材料的箔片，水平卷取心轴由支撑在一台机器机架的电机驱动，用来接收钢卷的带钢。并且至少有一个由电机调整的平滑辊来压紧带钢在卷取心轴上，分别为钢卷和平滑辊所需水平位置的控制，在水平导向的卷取心轴，通过调整操作气缸的控制力量来压紧平滑辊消除钢卷卷绕工艺所造成钢卷表面质量超出平滑度要求(DE 76 09 748 U1)。在绕成钢卷期间，当上面讨论类型的带钢卷取机滚动后，卷取带钢和箔片钢时就有相当数量的空气被纳入。传统的平滑辊可以消除这个唯一不足的问题。残余的空气被纳入钢卷将造成钢卷在卷取步骤的缺陷，如裂缝，曲折，和横向起伏可以导致生产出完全无用的钢卷。平滑辊和带钢卷取机一起配合实现两个功能。一方面，平滑辊相对钢卷压紧咬入带钢或箔片钢，其结果是一部分空气继续进入带钢或箔片钢后将被挤出来，而一部分空气造成钢卷内部创伤时被迫退出钢卷。另一方面，平滑辊实现矫直，带钢直边卷绕在卷取机卷筒上。所产生的问题是在一个带钢卷取机的平滑辊运行到钢卷卷绕倾斜后发生缺陷的带钢进入钢卷，例如板形缺陷由于长期或短期带钢的边缘，以及边缘粗糙度。因此，平滑辊，相对于钢卷要求通过压力缸方式，将同样会承担倾斜定位和将堵塞附有轧辊的杠杆支点，使带钢完美的卷绕在钢卷上但不再保证由于永久倾斜定位的平滑辊。倾斜定位和表面粗糙的薄板以及箔片带钢卷绕进入钢卷后将创伤卷筒导致平滑辊振动即动态惯性力产生并叠加在静态接触力的平滑辊上。动态惯性力的产生，尤其是在临界的振动范围的情况下，通过平滑辊附加在钢卷的冲击应力和损害的薄板或箔带钢，以及平滑辊。本文讨论发明的目的是开发一种可控制调整平滑滚动类型的带钢卷取机，允许其平稳运转，直边卷绕到卷取机的卷筒，并通过卷绕到最低限度来减少空气的纳入量。为了实现这一目标，本文讨论的带钢卷取机类型配有一个可控制调节所需位置的平滑辊，平行导向的卷取心轴，以及一个可控制调节钢卷上的带钢咬入点和平滑辊与钢卷的接触点之间的距离。平滑辊的工作气缸的调节方式带来平滑辊的水平所需位置以便使斜运行的薄板或箔带钢卷绕到钢卷并考虑由带钢缺陷或不可避免的粗糙度所引起卷筒上带钢表面的创伤在最短的时间内消除。调控平滑辊和带钢与钢卷第一次接触点之间的间距可以使不同直径的钢卷的平滑辊和带钢咬入点在最佳位置，以期最低空气进入钢卷。本发明将参考下面描述的带钢卷取机的示意图。在图纸：图1 带钢卷取机的侧视图 图S. 2a-2c 显示平滑辊控制水平位置的操作模式 图3 从图1左侧看设备垂直分布带钢卷取机1根据FIGS. 1和2卷绕和展开薄板或金属箔带2，它包括一个卷取心轴3为了接收钢卷5的卷筒4；卷取心轴旋转支持在一台机器的支架上并由两个装夹圆锥组成。带钢卷取机1设有一个平滑辊6安装在旋转杠杆7；通过压力缸8连接旋转杠杆7，平滑辊可以降低在钢卷5和升起。平滑辊6连接到旋转杆7或可选双旋转杠杆敦促对钢卷5在卷绕或展开薄板或箔片带钢2上或从卷取心轴3上的卷筒4采用双工作缸9，10连接平滑辊的两端6a, 6b；这些气缸可以调节控制力A, B。带钢卷取机1为了使平滑辊6水平移动到位置6而配备控制力，平行导向卷取心轴3，这种控制的调整是通过平滑辊6的工作气缸来控制力A, B大小实现并依赖于倾斜位置6，平滑辊6的6由缺陷引起的带钢2或不可避免的粗糙度的带钢2表面的伤口上的卷筒4。平滑辊6的偏差是从水平位置6 是由传感器11检测到。 控制调节平滑辊6的水平所需位置6在卷绕和展开箔带2上或从带钢卷取机1的卷筒4操作如下： 在卷取步骤开始时，通过平滑辊6的双工作气缸9, 10来控制力A, B设置在相同的所需值以及平滑辊6和钢卷2之间预定接触力C。根据FIG. 2a，适用下列关系： 如果箔片带钢2，按照插图FIG .2b，运行到钢卷5在倾斜中心位置考虑带带钢缺陷，接着平滑辊6通过双工作气缸9, 10来控制力A, B压紧钢卷5，假设中间倾斜位置6和水平位置6相关；这个位置6通过倾斜角度和传感器11检测来确定。在这一点，通过这种方式要经常对平滑辊6的位置进行控制，例如，控制力A要减少到期望值S的一半，控制力B要增加一半的期望值S，进而平滑辊6的结束端6b比另一端6a需要更大程度上抵压钢卷5。根据FIG. 2b，适用下列关系： 这种控制一直持续到箔片带钢2再次相对钢卷5水平，而且平滑辊6在假设的水平位置6。 根据FIG. .2c在平滑辊6到达假设最大位置6情况下，由倾斜角度，考虑到不合格的箔片带钢2进入到钢卷5，然后，通过控制平滑辊6的位置，例如工作气缸9的控制力A设置为0，工作气缸10的控制力B设置为预期值S的两倍直到箔片带钢2再次相对钢卷5水平，平滑辊6假设在水平预期位置6。在这个控制下，适用下列关系： 为了避免由缺陷薄板或者箔片带钢2卷绕与展开引起辊的振动而损伤钢卷5和平滑辊6，有定位切割平滑辊6位置调节或者设置平滑辊6的工作气缸9，,10来控制力A, B以一个最低值来快速通过平滑辊6某一共振值。 带钢卷取机1此外还设有控制能力为了调整钢卷5上带钢2的咬入点12和平滑辊6与钢卷5的接触点13之间距离，依赖于钢卷直径14。 远程控制操作最好是恒定的控制调节，该控制调节距离（a）从不同钢卷5的直径14到一个恒定值。 钢卷5上带钢2的咬入点12和平滑辊6与钢卷2的接触点13之间距离的远程调整可以通过旋转杠杆或杠杆7携带平滑辊6进行纵向调整，或者通过调整旋转杠杆或旋转杠杆7的枢轴点15。我们要求：1.带钢卷取机用来卷绕和展开薄带钢金属材料，有一个可旋转支撑的水平卷取心轴接收带钢，以及至少一个与卷取心轴相关的平滑辊调整来压紧相对钢卷的带钢，和平滑辊水平期望位置的调整控制；改善方式包括调节平滑辊（6）的位置(6)依赖平滑辊（6）的倾斜位置(6, 6)相对由不规则带钢(2)影响的卷取心轴，钢卷轴线的连接线和带钢第一次接触钢卷与相对钢卷平滑辊应用点的切点以及钢卷轴线由钢卷表面的相交点确定的距离(a)来隔开，该线由卷取心轴的轴线的尖锐反角远离轴线。有平直细长杆（7）承载平滑辊（6），并意味着杠杆（7）在一个水平方向的长度从而保持距离(a)尽管钢卷（5）直径是变化的。STRIP COILERInventors: Werner Stahl, Zum Hohlen Stein 20,D-57223 Keuztal; Josef Troster,Kurfurst-Heinrich-Strasse 27,D-57462 Olpe; Axel Barten, ImGensterfeld 20, D-5900Siegen-Sohlbach, all of Fed. Rep. ofGermanyAppl. No.: 896,926Filed: Jun. 1l, 1992Abstract: The strip coiler (1) for winding up and unwinding thin-gage and foil strip material of metal comprises a horizontal, motor-driven coiler mandrel (3) rotatably supported in a machine stand, for receiving the coiler reel(4) of a coil (5), and at least one smoothing roll (6)movable toward and away from the coiler mandrel (3)for pressing the strip (2) against the coil (5). The strip coiler (1) is equipped with control capability for the horizontal desired position of the smoothing roll (6)，oriented in parallel to the coiler mandrel (3), this control being performed by an adjustment of the controlling forces of the operating cylinders for pressing the smoothing roll (6) against the coil (5) in dependence on the inclined positioning of the smoothing roll (6 caused by defects in the strip (2) or by unavoidable out-of-roundness of the surface of the wound-up strip (2). The strip coiler (1) is furthermore provided with regulating means for setting the distance (a) between the point of first contact (12) of the strip (2) with the coil (5) and the contact point (13) of smoothing roll (6) and coil (5) in dependence on the coil diameter (14).STRIP COILER This application is a continuation of application Ser. No. 07/620,105, filed Nov. 30, 1990, now abandoned.The invention relates to a strip coiler for winding up and unwinding thin-gage and foil strip material of metal, with a horizontal coiler mandrel rotatably supported in a machine stand with a motor drive mechanism for receiving the coiler reel of a coil, and at least one smoothing roll adjustable by motor with respect to the coiler mandrel for pressing the strip against the coiler mandrel and, respectively, the coil, and with a control of the horizontal desired position of the smoothing roll, oriented in parallel to the coiler mandrel, by adjustment of the control forces of the operating cylinders for pressing the smoothing roll against the coil in dependence on the out-of-roundness of the coil caused by the winding process (DE 76 09 748 U1). Considerable amounts of air are incorporated during winding into the coil when coiling thin-gage and foil strip after rolling on a strip coiler of the type discussed above. A conventional smoothing roll can abolish this problem only inadequately. The residual air incorporated into the coil causes defects on the coil during the winding step, such as cracks, twists, and transverse undulations which can lead to the complete uselessness of the coil. The smoothing roll utilized together with the strip coiler fulfills two functions. On the one hand, the smoothing roller presses the entering thin-gage or foil strip against the coil, with the result that a portion of the air adhering to the entering thin-gage or foil strip is squeezed out, and a portion of the air wound into the coil is forced out of the coil. On the other hand, the smoothing roll takes care of a smooth, straight-edgedwinding up of the strip onto the coiler reel The problem arising in case of a strip coiler with smoothing roll is that the windings run obliquely onto the coil upon the occurrence of flaws in the strip entering the coil, such as flatness defects due to long or short strip edges, and edge roughnesses. As a result, the smoothing roll, urged against the coil by means of pressure cylinders, will likewise assume an inclined orientation and will jam in the pivot levers carrying this roll so that perfect windup of the strip onto the coil is no longer ensured due to the permanently inclined positioning of the smoothing roll. Strip windings entering the coil with oblique orientation and unavoidable out-of-roundnesses on the surface of the thin-gage and foil strip wound onto the coiler reel lead to vibration movements of the smoothing roll whereby dynamic forces of inertia occur which are superimposed on the static contact force of the smoothing roll. The dynamic inertial forces lead, particularly in case of critical vibration ranges, to an impact stress on the coil by the smoothing roll and to damage to the thin-gage or foil strip, as well as the smoothing roll. It is an object of the invention to develop a control for adjusting the smoothing roll of the strip coiler of the type discussed herein, permitting a smooth, straight edged windup of the strip onto the coiler reel, and reduction of the quantity of air incorporated by winding to a minimum.In order to obtain this object, the strip coiler of the type discussed herein is equipped with a control for setting the desired position of the smoothing roll, oriented in parallel to the coiler mandrel, and with a control for setting the distance between the entrance point of the strip on the coil and the contact point of smoothing roller and coil. The regulation by way of the operating cylinders of the smoothing roll brings about the horizontal desired position of the smoothing roll so that an oblique running up of the thin-gage or foil strip onto the coil on account of strip defects or unavoidable out-of-roundness of the surface of the strip wound onto the coiler reel is eliminated in a minimum period of time. The spacing regulation between the smoothing roll and the point of first contact of the strip with the coil makes it possible to optimally position the smoothing roll with respect to the strip entrance point for varying coil diameters, with a view toward a minimum incorporation of air into the coil. The invention will be described below with reference to schematic drawings of a strip coiler. In the drawings: FIG. 1 is a lateral view of the strip coiler; FIGS. 2a-2c show the mode of operation of the control for the horizontal desired position of the smoothing roll; and FIG. 3 is an elevational view of the device from the left of FIG. 1. The strip coiler 1 according to FIGS. 1 and 2 for the winding up and unwinding of a thin-gage or foil strip 2 of metal comprises a coiler mandrel 3 for receiving the coiler reel 4 of a coil 5;the coiler mandrel is rotatably supported in a machine stand and consists of two clamping cones. The strip coiler 1 is equipped with a smoothing roll 6 mounted on pivoting lever 7; by means of a pressure cylinder 8 engaging the pivot lever 7, the smoothing roll can be lowered onto the coil 5 and lifted off the latter. The smoothing roll 6 attached to the pivoting lever 7 or optionally two pivoting levers is urged against the coil 5 during the winding up or unwinding of a thin-gage or foil strip 2 onto or from the coiler reel 4 of the coiler mandrel 3 by means of two operating cylinders 9, 10 engaging the two ends 6a, 6b of the smoothing roll, the control forces A, B of these cylinders can be regulated. The strip coiler 1 is equipped with a control capability for the horizontal desired position 6 of the smoothing roll 6, oriented in parallel to the coiler mandrel 3,this control being carried out by adjustment of the control forces A, B of the operating cylinders 9, 10 of the smoothing roll 6 in dependence on the inclined position 6, 6 of the smoothing roll 6 caused by defects in the strip 2 or by unavoidable out-of-roundness of the surface of the strip 2 wound onto the coiler reel 4. Deviations of the smoothing roll 6 from the horizontal desired position 6 are detected by a sensor 11. The control for adjusting the horizontal desired position 6 of the smoothing roll 6 during the winding up and unwinding of a foil strip 2 onto or from the coiler reel 4 of the strip coiler 1 operates as follows: At the beginning of the coiling step, the control forces A and B of the two operating cylinders 9, 10 of the smoothing roll 6 are set at the same desired value S so that the predetermined contact force C is obtained between the smoothing roll 6 and the coil 2. According to FIG. 2a, the following relationships apply: If the foil strip 2, in accordance with the illustration it FIG. .2b, runs onto the coil 5 in a central oblique position on account of a strip defect, then the smoothing roll 6, pressed against the coil 5 by the control forces A, B of the operating cylinders 9, 10, assumes the central oblique position 6 with respect to the horizontal position 6; this position 6 is determined by the angle of inclination and is detected by the sensor 11. At this point, the positional control for the smoothing roll 6 becomes active in such a way that, for example, the control force A is reduced to half the desired value S, and the control force B is increased by half the desired value S, and thereby the end 6b of the smoothing roll 6 is urged to a greater extent against the coil 5 than the end 6a of the roll. According to FIG. 2b, the following relationships apply: The control remains operative until the foil strip 2 runs up against the coil 5 again horizontally, and the smoothing roll 6 has assumed the horizontal desired position 6. In case the smoothing roll 6 assumes the extreme inclined position 6 according to FIG. .2c, covered by the angle of inclination , on account of imperfect winding of the foil strip 2 entering the coil 5, then, by means of the positional control of the smoothing roll 6,for example the control force A of the operating cylinder 9 is set to a value of 0, and the control force B of the operating cylinder 10 is set at twice the desired value S until the foil strip 2 runs up on the coil 5 again horizontally, and the smoothing roll 6 assumes the horizontal desired position 6. With this control, the following relationships apply: In order to avoid damage to the coil 5 and the smoothing roll 6 due to a vibrating movement of the roll, triggered by flawed windup or unwinding of the thin-gage or foil strip 2, there is the positional of cutting out the positional regulation of the smoothing roll 6 or of setting the control forces A, B of the operating cylinders 9, 10 of the smoothing roll 6 to a minimum value as soon as the oscillations of the smoothing roll 6 surpass a critical value. The strip coiler 1 is furthermore equipped with control capability for adjusting the distance a between the entrance point 12 of the strip 2 at the coil 5 and the contact point 13 of the smoothing roll 6 and the coil 5,in dependence on the coil diameter 14. The distance control operates preferably as a constant control which regulates the distance a at varying diameters 14 of the coil 5 to a constant value.The distance regulation between the entrance point 12 of the strip 2 at the coil 5 and the contact point 13 of the smoothing roll 6 and the coil 2 can be conducted by a longitudinal adjustment of the pivoting lever or levers 7 carrying the smoothing roll 6, or by an adjustment of the pivoting point 15 of the pivoting lever or pivoting levers 7. We claim: 1. In a strip coiler for the winding up and unwinding of thin strip material of metal, with a rotatably supported horizontal coiler mandrel for receiving a coil of said strip, and at least one smoothing roll adjustable with respect to the coiler mandrel for pressing the strip against the coil, and with a control of the horizontal desired position of the smoothing roll; the improvement comprising means for regulating the position (6) of the smoothing roll (6) in dependence on an inclined position (6, 6) of the smoothing roll (6) relative to the coiler mandrel caused by irregularities in the strip (2), the line connecting the coil axis and the point of tangency where the strip first contacts the coil and the line between the point of application of said smoothing rollagainst the coil and the coil axis being spaced apart by a predetermined distance(a) at the points where said intersect the coil surface, said lines forming with the axis of the coiler mandrel an acute dihedral opening away from said axis, there being straight elongated levers (7) carrying the smoothing roll (6), and means for moving said levers(7) in a direction parallel to their length thereby to maintain said distance (a) constant despite changes in the diameter of the coil (5).
