Abstract

PROBLEM TO BE SOLVED: To easily and surely confirm the clutch-on only by attaching a simple means, by driving or stopping a motor for shaking to the normal or the reverse and the natural position with a three-positional type solenoid valve fitted to the shaking shaft of a shaking clamper and detecting the shaking angle with a sensor. SOLUTION: The clamper 1 is moved obliquely by working the shaking motor 6. The three-positional type solenoid valve 9 is positioned to the normal rotation side so as to flow oil to the shaking motor 6. The clamper 1 is pushed downward to the rear end part of a clutch lever 2 and a spring 3 becomes under compressing state and the upward force works at the tip part of the clamper, and an engage part 4 is taken out from the clutch 5 and becomes off-condition and a movable roller 13 can be shifted. A driving shaft 8 is rotated with another motor and the position of the movable roller 13 is changed to a prescribed position on a sleeve 16 of the driving shaft 8. The solenoid valve 9 is changed over to the neutral position and a working torque from the shaking motor 6 to the clamp 1 is stopped. The shaking angle is detected with the sensor 7 and in the case the shaking angle exceeds a threshold value, the clutch becomes on-condition.

The roller width changing device operates as follows. First, the clamper 1 attached to a bearing housing (not shown) at the end of the drive shaft 8 where the drive means is not provided.
Then, the rear end side of the clutch lever 2 is pressed downward, and the engaging portion 4 (inner blade) constituting the front end of the lever 2 is lifted up.
The clutch of the means for connecting the movable roller 13 to the sleeve 16 (formed of the gear clutch and the meshing portion) is disengaged, and the movable roller 13 is movable along the drive shaft 8. Then, in the screw portion 15 fixed to the movable roller 13, the driving shaft 8 is provided by a separately provided driving means (not shown).
Is rotated to move the movable roller 13, and the distance (width) between the fixed roller 14 and the movable roller 13 is set to a target value. After the movable roller 13 is fixed at that position, the pressing of the rear end side of the clutch lever 2 by the clamper 1 is released, and the force of the spring 3 built in the lower surface near the rear end of the clutch lever 2 releases the clutch. -Return the lever 2 to the original position, engage the tip engagement portion 4 with the gear clutch 5, and connect the clutch. As a result, the sleeve 16 of the drive shaft 8 and the rollers 13 and 14 can be integrally rotated.
The operation of the straightening machine is restarted.

However, such a straightening machine has a problem that it is structurally difficult to check the "disengaged" or "engaged" state of the clutch. That is, (1) Even if the position detecting sensor 7 is incorporated inside the roller width changing device, the drive shaft 8 and the roller width changing device rotate together, so that wiring for the sensor 7 becomes difficult. (2) When the non-contact type sensor 7 is arranged outside the roller width changing device, as shown in FIG. 5, during the change of the roller width, the sensor 7 is retracted from the straightening machine, and after the roller width is set, the sensor 7 is retreated. It is necessary to move the clutch lever 2 to a checkable distance above the clutch lever 2. For this reason, it is necessary to provide a special elevating means for the sensor 7, and the straightening machine has a complicated structure.

Further, the present invention sets a threshold value for the swing angle, and determines that the clutch is engaged when the swing angle detected after the solenoid valve is set to the neutral position exceeds the threshold value. This is a method of changing the roller width of the H-shaped steel roller straightening machine, characterized by making a judgment. According to the present invention, the so-called "engagement" or "disengagement" of the clutch formed by the tip meshing portion of the clutch lever attached to the movable roller side and the gear clutch attached to the sleeve side is performed by the swing shaft of the clamper. Can be easily confirmed by the information from the swing angle detecting sensor attached to one end of the sensor. As a result, erroneous operation of the straightening machine is reduced, and stable operation is ensured.

Embodiments of the present invention will be described below with reference to the drawings. FIGS. 1 and 2 show H according to the present invention.
4 shows a roller width changing device of a shape roller straightening machine. The rotation of the drive shaft 8 was stopped because the size of the section steel 12 being straightened was changed and the roller width had to be changed. In this state, the clutch is still engaged, and the movable roller 13 cannot move. Then, the swing motor 6 of the clamper 1 was operated to tilt the clamper 1. FIG.
(B) shows that the three-position type solenoid valve 9 is operating so that oil flows to the swing motor 6. That is, the solenoid valve 9 is located on the normal rotation side (← in the figure is the direction in which oil flows). Thereby, the clamper 1
Pushes the rear end of the clutch lever 2 downward, the spring 3 attached to the lower surface of the clamp lever 2 is in a compressed state, and an upward force acts on the distal end.
Get out of clutch 5. The so-called clutch is in the “disengaged” state, and the movable roller 13 can be moved.

Next, the drive shaft 8 is rotated by a separately provided hydraulic motor, and the screw portion 1 fixed to the movable roller 13 is rotated.
5 to change the position of the movable roller 13 to a predetermined position on the sleeve 16 attached to the drive shaft 8. When the position change is completed, the three-position solenoid valve 9 that supplies oil to the swing motor 6 is switched to the neutral position, and the operating torque from the swing motor 6 to the clamper 1 is cut off. As a result, the spring 3 that has been in a compressed state expands, and the rear end of the clamper 1 rises via the clutch lever 2. This state is shown in FIGS. 2A and 2B, in which the meshing portion 4 at the tip of the clutch lever 2 is conversely lowered and falls between the blades of the gear clutch 5. The swing angle of the clamper 1 at this time is detected by the sensor 7 and compared with a predetermined threshold value. Note that this threshold value is determined in a state where the meshing portion 4 at the tip of the clutch lever 2 is completely fitted into the gear clutch 5. Therefore, when the swing angle exceeds the threshold value, it is completely engaged (the clutch is "engaged"). Then, since the sleeve 16 attached to the drive shaft 8 has been restored so as to rotate together with the movable roller 13, the drive shaft 8 is rotated to start shape correction of the shaped steel 12 after the size change. Note that the threshold value may be set appropriately, but is generally 3 to 5 degrees.

As described above, according to the present invention, the swing angle of the clamper can be detected and the so-called "engaged" state of the clutch can be confirmed by a simple modification of the straightening machine currently used. It became so. As a result, the work of changing the roller width has become quicker, and there has been no erroneous operation of the straightening machine.
