In this embodiment, when the emergency stop means operates, the rolls 2 and 2 stop within one-third of the rotation, but the present invention is not limited to this.

Since the stop control circuit of the emergency stop means can be simply constructed by using a conventionally well-known logic circuit technique, a detailed description thereof will be omitted.

The emergency separating means 6 controls the rotational force of the motor 9 and the drive shaft of the motor by the adjusting handle 7 of the distance setting means 3.
And a pair of gears 10 and 11 for transmitting to the rotating shaft 8.

In the emergency separating means 6, the motor 9 receives an electric signal generated when the rolls 2, 2 are stopped by the operation of the emergency stop means, and rotates in a direction for separating the rolls 2, 2. The shaft 8 is rotated.

In FIG. 4, reference numeral 12 denotes a forward rotation button for rotating the rolls 2 and 2 of the rubber processing apparatus 1 forward, and reference numeral 13 denotes a reverse rotation button for rotating the rolls 2 and 2 in reverse.

Next, the operation of this embodiment will be described.
First, when performing flattening of rubber, the rubber processing device 1
The distance between the rolls 2 and 2 is set at both ends thereof by rotating the adjusting handles 7 and 7 of the distance setting means 3 and 3, respectively, and performing fine adjustment.

The rubber processing apparatus 1 usually has a normal rotation button 12
Is pressed to perform the flattening processing of the rubber, and the rolls 2 and 2 can be reversed by pressing the reverse rotation button 13.

If the worker's hand is pinched between the rolls 2 and 2 during the normal rotation of the rolls 2 and 2, a part of the worker's body touches one of the emergency stop bars 4 and 5.

Then, the emergency stop means operates, and the rolls 2 and 2 are stopped urgently because power supply to the drive unit is stopped, and the stop signal of the rolls 2 and 2 is sent to the emergency separation means 6 and 6. Is output to As a result, the motors 9, 9 of the emergency separating means 6, 6 are driven to rotate, the rotating shaft 8 is forcibly rotated at high speed, and the rolls 2, 2 are quickly separated.

At this time, even if a reset button (not shown) for restoring the interval between the rolls 2 and 2 is pressed, the motors 9 and 9 of the emergency separating means 6 and 6 do not stop until the interval reaches the maximum. I have.

In this embodiment, the maximum interval between the rolls 2 and 2 is, for example, 20 millimeters, and is ensured within 10 seconds.
