No. 07/620,105, 提交1990年11月30日，現(xiàn)在已經(jīng)被廢棄。本發(fā)明涉及到帶鋼卷取機(jī)卷繞和開卷薄帶鋼和金屬材料的箔片，水平卷取心軸由支撐在一臺機(jī)器機(jī)架的電機(jī)驅(qū)動，用來接收鋼卷的帶鋼。并且至少有一
3、個(gè)由電機(jī)調(diào)整的平滑輥來壓緊帶鋼在卷取心軸上，分別為鋼卷和平滑輥所需水平位置的控制，在水平導(dǎo)向的卷取心軸，通過調(diào)整操作氣缸的控制力量來壓緊平滑輥消除鋼卷卷繞工藝所造成鋼卷表面質(zhì)量超出平滑度要求(DE 76 09 748 U1)。在繞成鋼卷期間，當(dāng)上面討論類型的帶鋼卷取機(jī)滾動后，卷取帶鋼和箔片鋼時(shí)就有相當(dāng)數(shù)量的空氣被納入。傳統(tǒng)的平滑輥可以消除這個(gè)唯一不足的問題。殘余的空氣被納入鋼卷將造成鋼卷在卷取步驟的缺陷，如裂縫，曲折，和橫向起伏可以導(dǎo)致生產(chǎn)出完全無用的鋼卷。平滑輥和帶鋼卷取機(jī)一起配合實(shí)現(xiàn)兩個(gè)功能。一方面，平滑輥相對鋼卷壓緊咬入帶鋼或箔片鋼，其結(jié)果是一部分空氣繼續(xù)進(jìn)入帶鋼或箔片鋼后將被擠出來，而
4、一部分空氣造成鋼卷內(nèi)部創(chuàng)傷時(shí)被迫退出鋼卷。另一方面，平滑輥實(shí)現(xiàn)矯直，帶鋼直邊卷繞在卷取機(jī)卷筒上。所產(chǎn)生的問題是在一個(gè)帶鋼卷取機(jī)的平滑輥運(yùn)行到鋼卷卷繞傾斜后發(fā)生缺陷的帶鋼進(jìn)入鋼卷，例如板形缺陷由于長期或短期帶鋼的邊緣，以及邊緣粗糙度。因此，平滑輥，相對于鋼卷要求通過壓力缸方式，將同樣會承擔(dān)傾斜定位和將堵塞附有軋輥的杠桿支點(diǎn)，使帶鋼完美的卷繞在鋼卷上但不再保證由于永久傾斜定位的平滑輥。傾斜定位和表面粗糙的薄板以及箔片帶鋼卷繞進(jìn)入鋼卷后將創(chuàng)傷卷筒導(dǎo)致平滑輥振動即動態(tài)慣性力產(chǎn)生并疊加在靜態(tài)接觸力的平滑輥上。動態(tài)慣性力的產(chǎn)生，尤其是在臨界的振動范圍的情況下，通過平滑輥附加在鋼卷的沖擊應(yīng)力和損害的薄板或箔
5、帶鋼，以及平滑輥。本文討論發(fā)明的目的是開發(fā)一種可控制調(diào)整平滑滾動類型的帶鋼卷取機(jī)，允許其平穩(wěn)運(yùn)轉(zhuǎn)，直邊卷繞到卷取機(jī)的卷筒，并通過卷繞到最低限度來減少空氣的納入量。為了實(shí)現(xiàn)這一目標(biāo)，本文討論的帶鋼卷取機(jī)類型配有一個(gè)可控制調(diào)節(jié)所需位置的平滑輥，平行導(dǎo)向的卷取心軸，以及一個(gè)可控制調(diào)節(jié)鋼卷上的帶鋼咬入點(diǎn)和平滑輥與鋼卷的接觸點(diǎn)之間的距離。平滑輥的工作氣缸的調(diào)節(jié)方式帶來平滑輥的水平所需位置以便使斜運(yùn)行的薄板或箔帶鋼卷繞到鋼卷并考慮由帶鋼缺陷或不可避免的粗糙度所引起卷筒上帶鋼表面的創(chuàng)傷在最短的時(shí)間內(nèi)消除。調(diào)控平滑輥和帶鋼與鋼卷第一次接觸點(diǎn)之間的間距可以使不同直徑的鋼卷的平滑輥和帶鋼咬入點(diǎn)在最佳位置，以期最低
6、空氣進(jìn)入鋼卷。本發(fā)明將參考下面描述的帶鋼卷取機(jī)的示意圖。在圖紙：圖1 帶鋼卷取機(jī)的側(cè)視圖 圖S. 2a-2c 顯示平滑輥控制水平位置的操作模式 圖3 從圖1左側(cè)看設(shè)備垂直分布帶鋼卷取機(jī)1根據(jù)FIGS. 1和2卷繞和展開薄板或金屬箔帶2，它包括一個(gè)卷取心軸3為了接收鋼卷5的卷筒4；卷取心軸旋轉(zhuǎn)支持在一臺機(jī)器的支架上并由兩個(gè)裝夾圓錐組成。帶鋼卷取機(jī)1設(shè)有一個(gè)平滑輥6安裝在旋轉(zhuǎn)杠桿7；通過壓力缸8連接旋轉(zhuǎn)杠桿7，平滑輥可以降低在鋼卷5和升起。平滑輥6連接到旋轉(zhuǎn)桿7或可選雙旋轉(zhuǎn)杠桿敦促對鋼卷5在卷繞或展開薄板或箔片帶鋼2上或從卷取心軸3上的卷筒4采用雙工作缸9，10連接平滑輥的兩端6a, 6b；這些氣
7、缸可以調(diào)節(jié)控制力A, B。帶鋼卷取機(jī)1為了使平滑輥6水平移動到位置6而配備控制力，平行導(dǎo)向卷取心軸3，這種控制的調(diào)整是通過平滑輥6的工作氣缸來控制力A, B大小實(shí)現(xiàn)并依賴于傾斜位置6，平滑輥6的6由缺陷引起的帶鋼2或不可避免的粗糙度的帶鋼2表面的傷口上的卷筒4。平滑輥6的偏差是從水平位置6 是由傳感器11檢測到。 控制調(diào)節(jié)平滑輥6的水平所需位置6在卷繞和展開箔帶2上或從帶鋼卷取機(jī)1的卷筒4操作如下： 在卷取步驟開始時(shí)，通過平滑輥6的雙工作氣缸9, 10來控制力A, B設(shè)置在相同的所需值以及平滑輥6和鋼卷2之間預(yù)定接觸力C。根據(jù)FIG. 2a，適用下列關(guān)系： 如果箔片帶鋼2，按照插圖FIG .2

9、然后，通過控制平滑輥6的位置，例如工作氣缸9的控制力A設(shè)置為0，工作氣缸10的控制力B設(shè)置為預(yù)期值S的兩倍直到箔片帶鋼2再次相對鋼卷5水平，平滑輥6假設(shè)在水平預(yù)期位置6。在這個(gè)控制下，適用下列關(guān)系： 為了避免由缺陷薄板或者箔片帶鋼2卷繞與展開引起輥的振動而損傷鋼卷5和平滑輥6，有定位切割平滑輥6位置調(diào)節(jié)或者設(shè)置平滑輥6的工作氣缸9，,10來控制力A, B以一個(gè)最低值來快速通過平滑輥6某一共振值。 帶鋼卷取機(jī)1此外還設(shè)有控制能力為了調(diào)整鋼卷5上帶鋼2的咬入點(diǎn)12和平滑輥6與鋼卷5的接觸點(diǎn)13之間距離，依賴于鋼卷直徑14。 遠(yuǎn)程控制操作最好是恒定的控制調(diào)節(jié)，該控制調(diào)節(jié)距離（a）從不同鋼卷5的直徑1

16、ER 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
17、 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
18、 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 incorp
19、orated 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 s
20、tep, 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
21、 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
22、 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
23、 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
24、 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 smoothin
25、g 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 smoo
26、thing 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 equipp
27、ed 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 opera
28、ting 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 eli
29、minated 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 minimu
30、m 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 smoothin
31、g 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 rotat
32、ably 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 smo
33、othing 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
34、 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 th
35、e 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 smoothi
36、ng 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 beg
37、inning 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
38、 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 obliqu
39、e 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 th
40、e 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 unti
41、l 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
42、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
43、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
44、 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
45、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 con
46、trol 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
47、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 sup
