This operation is called recoiling and is illustrated in Fig.12-7.The compass direction indicate
2、d in Fig. 12-7(a) will be used to specify direction of movement in the discussion of the recoiling system. This will help avoid confusion.当一个条状材料完成工序，它会被卷绕成线圈以便随后的处理和发运。这个操作就叫做卷取，在图 12-7 展示。图 12-7 标示的指南针方向将被用来指定讨论卷取系统中的运动方向。这将有利于避免混乱。The moving strip passes under a fixed idler roll and is recoiled o
3、n the windup reel. If the recoiling operation consisted merely of rotating the windup reel and feeding the strip onto it, the coil laps would not be aligned with each other ;the sides would either be wavy ortelescoped.This would make handling and shipping the coil more difficult and would increase t
4、he likelihood of edge damage.移动的条从固定托辊底下穿过，缠绕卷筒上向后反冲。如果反冲操作只是由旋转缠绕卷筒和喂养条组成，产生的线圈几乎肯定是歪的。也就是说，单独线圈的圈不会和其他的圈相互对齐;两侧将是波浪形或“套叠” 。这将使得处理和运输线圈更困难，并会增加的边缘损坏的可能性。To produce straight coils,some type of control is necessary to ensure that every coil lap is aligned with every other lap.There are two ways to do
5、 this:1. Guide the straight strip to correct any tendency it has to move laterally(back and forth) relative to a fixed windup reel.2. Shift the windup reel back and forth to follow any lateral movement by the traveling strip.为了生产直的卷，某些形式的的控制来保证每个圈都和其他的对齐是很必要的。下面介绍两种方法：1.引导直条，以纠正任何倾向，它具有横向移动（来回）相对于一个
6、固定的缠绕卷轴。2.移位缠绕卷筒，来回由移动带任何横向移动。Of these two methods,the second is preferred for most strip material,especially metal strip.The position of the windup reel is usually controlled by a hydraulic cylinder. The cylinder rod is attached to the mounting base of the reel,as shown in Fig.12-7(a). The position
7、-sensing device is a large photoconductive cell,with a diameter of about 1 in.A view of the photoelectric edge-sensing assembly is presented in Fig.12-7(b);this is the view seen looking toward the east along the top of the traveling strip.If the strip is properly positioned,it will block exactly hal
8、f of the broad light beam radiated by the lamp. The other half of the light beam will strike the photocell.在这两种方法中，优选所述第二对于大多数带钢材料，特别是金属条带。缠绕卷轴的位置通常是由一个控制液压缸。缸杆附连到安装的基础上的卷轴，如在图 12 中，图 7（a）所示。位置检测的移动设备是一个大的感光体单元，具有直径为约 1。一个边缘感应组件的光电在图 12 中，图 7（b） ，这是只向东看沿的行进带的顶部。如果钢带是正确定位，它会阻止正好有一半的广泛光束由灯发射。光束的另一半将打到
9、光电池。If the traveling strip should wander to the south,deeper into the photoelectric assembly,a smaller amount of light will strike the photocell. This will be detected electrically and will initiate control action to move the windup reel to the south,to keep it aligned with traveling strip.如果移动到南的移动
10、带，更深入的光电组件，更小的光量会触击光电。这将检测到的电，将启动控制操作，将缠绕的卷到南部，以保持对齐移动条。If the strip should wander to the north,out of the photoelectric assembly,the increasing illumination of the photocell will cause the windup reel to move to the north.Figure 12-7(a) shows that the edge sensor is mounted on an arm which is attac
11、hed to the windup reel base.The edge sensor thus moves with the windup reel,always maintaining a fixed strip edge position relative to the reel. In this way the windup reel is kept constantly aligned with the strip.Every coil lap edge aligns with every other coil lap edge,and the coil winds straight
12、.如果带移动到北，出了光电组件，增加照明的光电池会造成缠绕的卷移动到北部。图 12-7（a）表示的边缘的传感器被安装在一个臂，该臂是连接到缠绕卷轴基座。移动边缘传感器缠绕卷筒，始终保持一个固定的带材边缘位置相对于所述带盘。以这种方式，缠绕卷盘保持带材不断对齐。每个线圈的圈边缘对齐每另一个线圈一圈边缘，和线圈风直。The electrohydraulic circuit which accomplishes this control is shown in Fig.12-8.There is how it works. The photoconductive cell in the edge s
13、ensor has an approximate resistance of 5 kOm when the traveling strip blocks half of the light beam.The bias adjustment pot,P1,is adjusted to turn on transistor Q1 enough to bring its collector voltage to about 2 V. Q1 collector voltage is applied to the base of power transistor Q2.This cause Q2 to
14、conduct,establishing a current flow in the 320-om actuator coil that swings the hydraulic jet pipe. 实现这种控制的电液电路如图 12-8 所示。还有它是如何工作的。边缘传感器的光电导的电池中有一个近似的电阻为 5 K 的移动带块一半时，如果光束。该偏置调整的锅，P1，调整打开足以使晶体管Q1 的集电极电压至约 2 V. Q1 的集电极电压被施加到功率晶体管 Q2的基极。这种原因 Q2 进行，建立在 320-奥姆摆动液压射流管的致动器线圈的电流流动。The jet pipe assembly is
15、 designed so that a 10-m A current through the actuator coil causes the jet pipe to be perfectly centered.Adjustment of the center position is done with the balancing spring adjustment .The mechanical force exerted by the balancing spring is equal and opposite to the force created by the permanent m
16、agnet and actuator coil.射流管组件被设计成使得通过致动器线圈 10 mA 的电流引起的射流管完全居中。中心位置的调整是通过平衡弹簧的调整。平衡弹簧所施加的机械力是由永久磁铁产生的力和致动器线圈相等，方向相反。In Fig.12-8(a),bias pot P1is manually adjusted to provide exactly half blocked.Lowering the P1 resistance increases the current in the actuator coil, and raising the P1 resistance decreases the coil current .The adjustment of P1 would be done by the system users prior to putting the system in service.在图 12 中，图 8（a） ，偏置 P1 被手动调整，以提供恰好有一半被阻止。的 P1 阻力降低增加了在致动器线圈的电流，和提高的P1 电阻的 P1 的调整
