In recent years, in the preparation of soft products, screws,
1.When tying 6 knots, the so-called PP sexual region fastening is now performed, which completes the transition from the 9iii sexual region to the plastic region once at a prescribed rotation angle. However, in the torque gravity of the nut runner, there is a shift from the elastic region to the plastic region.
It is difficult to detect boundary points in ft rows without error.
Therefore, the torque of I'itJ, which is one generation higher than the torque of positive 11j, which makes 1'J [desired Llii-1 land connection, is one generation, is the torque of I'itJ. There are some drawbacks.

If the rotational speed of the tool is constant, the bearing surface of the screw is fully seated (
・"1 Luk is EJI 6.1 angle α as shown in Figure 1. I! Generally speaking, it rises at the P point, and once it passes the P point, the 1st grade singer becomes an IL fence. This point P becomes the boundary point between the elastic region and the plastic region. The first thing to do is to pre-tighten the plastic region and tighten the screws at an angle θ1 one more time from the -P point. The indispensable condition for the conventional device to achieve this fourfold fastening is to reliably capture point 1. The IC that takes the point P differentiates the torque addition multiplied by 1 to the rotation angle and shows that the candy is greater than a constant 1.
In other words, the rotation angle of the opponent's hand is dθ, the torque increase 5i @ d'l between the rotation angles 10 and the deviation (dT/dθ−
It can be expressed as La++α. Furthermore, since dT/dlJ=0 after point P, point P can be detected when dT/dθ becomes less than a certain value.

However, in actual fastening, as shown in Figure 1, the magnitude of the torque varies smoothly in some cases, with ups and downs over the entire period, and in other cases it changes smoothly, but as shown in Fig. There are cases where the undulations (unevenness) are arranged in an upper row by one and a half. Therefore, if at a certain intermediate Px point, dT/
If dθ is 0, then consider this point as point P and increase the θ1 degree from there, resulting in a fastening like the broken line in Figure 2, which is far from the actual fastening torque shown by the solid line. Therefore, only low torque tightening is required.

The present invention reliably eliminates the above-mentioned malfunctions,
In principle, it is not necessary to detect the boundary q1 between the elastic region and the plastic region.

Store θ2 and the torque T2 at that time in the peak memory circuit described later, and when the θ1 angle elapses from point PO, the memorized value shown in 11] appears, and the torque T2 is memorized. At the second rising value To/θ2, the upper evening is 1. Step 1: Stop the screw fixing device at the intersection of the increasing torque value and the actual fastening torque. The connection to this point is the same as in the case of 01 degrees 1i1i from point P, and it is possible to make a correct connection even without capturing point P.
