This tension control is generally referred to as taper control, and typically, as the diameter of the sheet roll being wound increases, the winding tension is gradually weakened to avoid the winding phenomenon. In this case, in order to weaken the winding tension, the winding torque of the winding shaft drive mechanism of the winding machine is weakened, which is also called torque control.

4 has also been used for control, but there is a problem in that the transmission mechanism and the device itself become complicated.
Moreover, since it directly acts on the drive motor and does not control its output, it is inconvenient and increases mechanical loss.

It is composed of a load cell 7. Further, as specifically shown in FIG. 4, the load cell 7 is attached to its holding member 7a, and the mounting frame side member 5a is attached to the load cell 7.
The initial pressing force applied to the load cell 7 is adjusted by the adjusting screw 5b and the tightening nut 5c passing through the adjusting screw 5b.

が、概略的事項は同様である。 Now, FIG. 5 is a product of the configuration shown in FIGS. 3 and 4, and represents one set of the three sets of winding sections shown in FIG. 2. Since the prime mover shaft 4a is connected by a coupling ring 11 and the winding shaft A is the winding core, a winding core holding adapter 12 is attached to the tip of the support arm 1a, and the structure is such that it can be pushed and pulled by a fluid pressure cylinder 13. Although there are some differences, the general points are the same.
次に、第６，７図は別の実施例の要部を示すも

This embodiment differs from the previous embodiment in that the restraining body 6 on the side of the winding shaft support 1 is sandwiched by b.

By slightly recessing the side surface of the motor shaft 4a and accommodating the detection parts such as the stopper 6 and the load cell 7 there, the motor shaft 4a
A pulley 9 is attached to this so that the winding shaft drive belt 10 can be directly hung thereon without adding any additional parts.

The axes of a and the prime mover mounting frame shaft portion 5p are aligned. Therefore, the torque due to the motor drive reaction force during the winding operation, that is, the winding torque, is generated by the load cell 7.
It can be easily obtained by simply multiplying the pressing force detected by the distance from the common axis line to the load cell 7.

な計算は制御部で行うので、諸々の条件に従い、
補正を行うことも可能である。 However, as shown in FIGS. 10 and 11, the axes of the two do not necessarily have to match. Since the axes do not have to match, the prime mover 4 can also be housed in the hole made in the support arm 1a of the winding shaft support 1, in line with the prime mover mounting frame shaft portion 5p. In other words, since there is some clearance in the hole, the prime mover 4 can swing due to the reaction force. However, in reality, the motor mounting frame member 5a with the load cell 7 attached is mounted on two support arms 1.
The structure is such that it is held between the a-side stopper 6 and the reaction force is measured without moving it. Then, the load cell 7 is connected to the measured pressure force of the load cell 7 from the prime mover mounting frame shaft portion 5p.
By multiplying by the distance up to this point, the torque of the reaction force, that is, the winding torque can be obtained. Of course, such calculations are done in the control section, so according to various conditions,
It is also possible to make corrections.

This winding tension or torque control diagram is a graph obtained by obtaining data on the relationship between the winding amount and the required tension or torque in order to obtain a high-quality rolled sheet roll. It is. and,
In order to prevent the occurrence of the winding phenomenon and other phenomena that result in product defects, as the wound sheet roll R grows, the winding tension is weakened, for example, and a straight line or curve suitable for the sheet tension-winding amount diagram is set. Make it so that In addition, in order to obtain such a tension-winding amount diagram, a torque control diagram may be set, for example, to suppress the increasing tendency of winding torque that increases as the winding diameter or winding length increases. . These control diagrams are then set in the setting section of the winding tension or winding torque control device. Therefore, in the setting section applied in such torque control, when the winding amount detection signal is input, the set tension or set torque corresponding to the winding amount based on the control diagram is determined and output. .

指令する。 In this embodiment, the detection device 15 detects an increase in the radius of the sheet roll R, thereby detecting the amount of winding. As the radius increases, the amount of winding per revolution of the winding shaft increases, so it is necessary to reduce the number of revolutions by that amount. The rotational speed is determined and a command is given to the motor control device 14.
