[0001]

BACKGROUND OF THE INVENTION This invention relates to an improvement of a noodle strip rolling mill.

[0002]

2. Description of the Related Art As shown in FIG. 1, a pair of rolling rolls 51 and 52, which are opposed to each other and are arranged above and below each other, are provided with a certain interval, and the pair of rolling rolls 51 and 52 are opposed to each other. When the noodle dough formed into a rod shape or a strip shape is fed between the rolling rolls 51 and 52 while being forcedly rotated in the direction, the noodle strip A is rolled between the pair of rolling rolls 51 and 52. The rolling machine 53 for rolling noodle strips is already known.

Further, as shown in FIG. 1, a plurality of noodle strip rolling machines 53, 53, ... As described above are arranged in series, and an interval between each pair of rolling rolls 51, 52 in each rolling machine. They are, for example, 15mm, 12mm, 8m
If it is set to be successively smaller, such as m, 6 mm, and 4 mm, the noodle strips A are successively thinned by the series of noodle strip rolling machines 53, 53 ... It is disclosed in, for example, Japanese Utility Model Publication No. 43-478.

[0004]

However, a plurality of noodle strip rolling machines 53 having the above-described structure have a plurality of noodle strip rolling machines 53 arranged in series even if they are arranged in series. The rod-shaped or thick strip-shaped noodle dough that is sent to the rolling device 54 is produced by kneading a predetermined amount of powder and water mixed in a batch manner, and thus the noodle strip rolling. A certain amount of noodle dough is intermittently fed into the rolling start end of the device 54 in a state of being interrupted.

Therefore, in the noodle strip rolling apparatus 54 having the above-described structure, the supply of noodle dough is once interrupted, and then the next rod-shaped or strip-shaped noodle dough is newly fed to the rolling start end portion. Occasionally, it is necessary to manually feed the front end portion of the newly fed noodle strip A between the pair of upper and lower rolling rolls for each noodle strip rolling machine 53. is there.

That is, the vicinity of the front end of the noodle strip A is gripped by the hand 55 and carried to the lower rolling roll 52 of the noodle strip rolling machine 53, and as shown in FIG. The tip end is pressed against the surface of the lower rolling roll 52 rotating in the direction of the arrow so that the noodle strip A does not slip off the surface of the lower rolling roll 52, and the noodle strip A slides off the surface of the lower rolling roll 52. Do not touch the tip of noodle strip A by hand 5
In the state of being pressed against the rolling roll 52 in 5, the hand 55 is advanced in accordance with the rotation of the rolling roll 52, and the pair of upper and lower rolling rolls in which the leading ends of the noodle strips A rotate in mutually opposite directions (arrow directions) A series of noodle strip rolling machines 53 is a manual operation in which the hand 55 has to be released from the noodle strip A promptly when the time when it is completely bitten between 51 and 52.
Required for each.

However, the operation of supplying the leading end portion of the noodle strip A between the upper and lower rolling rolls 51 and 52 of each noodle strip rolling machine 53 is as follows.
If you release your hand 55 from noodle strip A before it is sandwiched,
The front end of the noodle strip A slips off from the surface of the lower rolling roll 52 due to the weight of the rear portion thereof, and the eyes are erroneously measured or careless.
If the time to release is delayed, the hand 55 will be caught between the upper and lower rolling rolls 51 and 52 that are forcibly rotated in opposite directions (arrow directions), which is very dangerous.

Therefore, in the conventional apparatus, when the hand 55 is mistakenly caught between the upper and lower rolling rolls 51 and 52, each noodle strip rolling machine 53 is arranged at an appropriate position. There is a push-button switch (not shown) which is provided to stop the rotation of the noodle strip rolling machine 53.

However, once one hand is sandwiched between the pair of rolling rolls 51 and 52, it is quite difficult to press the push button switch with only the other hand in such a state, which is very dangerous. Met.

Further, the conventional device is
Fortunately, even if the noodle strip rolling device can be stopped by pressing the push button switch, in order to remove the hand once sandwiched between the upper and lower rolling rolls 51 and 52 from between the rolling rolls, In the conventional device, the bearing of one of the rolling rolls 52 (or 51), which is supported so as to be vertically movable, is moved while waiting for the rescue of another worker, and the gap between the upper and lower rolling rolls 51, 52 is increased. I had to unfold it, so it took me a long time to be able to pull out my trapped hands.

The above-mentioned danger was extremely great in the noodle strip rolling machine 53 on the front side where the distance between the upper and lower rolling rolls 51 and 52 was relatively large.

Therefore, the present invention aims to eliminate the danger in the noodle strip rolling machine as described above, and even if the hands are mistakenly caught between the upper and lower rolls, the upper and lower rolls are rolled. It is an object of the present invention to provide an improved noodle strip rolling mill so that the roll can be quickly pulled out from between rolls.

[0013]

It is connected to the power supply through the forward / reverse control circuit of the electric motor, which is not provided in the road, and that the operator's hand approaches the rolling space of the noodle strip more than a predetermined amount to the proper place of the noodle strip rolling machine. By providing a danger detection switch that closes when detected, the danger detection switch is inserted in the forward / reverse control circuit of the electric motor as a switch for closing the electric motor reverse electromagnetic switch. It is to prevent an operator's hand from being caught in the rolling space of the noodle strip, and another one of the technical means taken by the present invention is that the noodle strip rolling machine is provided with the pair of rolling rolls. Drive source is constituted by an induction motor, and the induction motor does not have an electrical interlock contact for preventing reverse rotation at the time of forward rotation in the circuit for reverse rotation of the motor. Connected to At least one emergency operation switch that is placed in a proper place of the noodle strip rolling machine and closes when operated is provided with the emergency operation switch, and the emergency operation switch is provided in a forward / reverse control circuit of the electric motor. By inserting it as a switch for closing the electromagnetic switch for reversing, when the hand of the worker is caught in the rolling space of the noodle strip, the hand is quickly pulled out from the rolling space. That is what I was able to do.

In any of the above technical means, it is more preferable that the forward / reverse rotation control circuit of the electric motor is configured so that the reverse rotation of the electric motor caused by the closing of the electromagnetic switch for reverse rotation of the electric motor is constant.
