[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to improvement of a noodle strip rolling mill.

[0002]

[Prior art]

 As shown in FIG. 1, a certain distance is provided between a pair of rolling rolls 51 and 52 arranged facing each other, and the pair of rolling rolls 51 and 52 are forced in opposite directions. When the noodle dough formed into a rod shape or a band shape is fed between the rolling rolls 51 and 52 while being rotated, the noodle band A is rolled between the pair of rolling rolls 51 and 52. The rolling mill 53 of 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 between each pair of rolling rolls 51, 52 in each rolling machine. When the intervals are set to be successively smaller, for example, 15 mm, 12 mm, 8 mm, 6 mm, 4 mm, a series of noodle strip rolling machines 53 constituting this noodle strip rolling device 54. It is also disclosed, for example, in Japanese Utility Model Publication No. 43-478 that the noodle strips A can be rolled so as to be gradually thinner.

[0004]

[Problems to be solved by the device]

 However, the plurality of noodle strip rolling machines 53 having the above-described structure are fed to the noodle strip rolling apparatus 54 composed of a row of the noodle strip rolling machines 53 even if they are arranged in series. Since the rod-shaped or thick strip-shaped noodle dough is produced by kneading a predetermined amount of powder and water mixed in batches, the rolling start end of the noodle strip rolling device 54 has , A certain amount of noodle dough is sent in intermittently intermittently.

Therefore, in the noodle strip rolling apparatus 54 having the above-described configuration, after the supply of the noodle dough is interrupted once, the next rod-shaped or strip-shaped noodle dough is newly fed to the rolling start end portion. Occasionally, it is necessary to manually supply the leading end of the newly-fed noodle strip A to each 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 upper part of 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 noodles do not slip off from the surface of the lower rolling roll 52, and the noodle strip A slides from the surface of the lower rolling roll 52. While keeping the vicinity of the front end of the noodle strip A against the rolling roll 52 with the hand 55 so as not to fall, the hand 55 is advanced in accordance with the rotation of the rolling roll 52, and the front ends of the noodle strip A are directed in opposite directions ( A series of manual operations, such as having to release the hand 55 from the noodle strip A promptly at the time when it is completely bitten between the pair of upper and lower rolling rolls 51 and 52 rotating in the arrow direction), Necessary for each noodle strip rolling machine 53 is there.

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 remove your hand 55 from the noodle strip A before it is sandwiched between them, the tip of this noodle strip A will slip off from the surface of the lower rolling roll 52 due to the weight of the rear portion of the noodle strip A, and the measurement will be incorrect. Or, if it is careless and the time to release the hand 55 from the noodle strips is delayed, the hand 55 is caught between the upper and lower rolling rolls 51 and 52 that are forcibly rotated in opposite directions (arrow directions). It will be very dangerous.

Therefore, in the conventional apparatus, if the hand 55 is mistakenly sandwiched between the upper and lower rolling rolls 51 and 52, each of the noodle strip rolling machines 53 is arranged at an appropriate position. There is a device in which the rotation of the noodle strip rolling machine 53 can be stopped by pushing a push button switch (not shown).

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

In addition, in the conventional device, even if the noodle band rolling device can be stopped by pressing the push button switch fortunately when the hand is caught, even if the upper and lower rolling rolls 51. In order to remove the hand sandwiched between the rolling rolls 52 between the rolling rolls 52, in the conventional device, one of the rolling rolls 52 (or the rolling rolls 52 (or Since the bearing of 51) had to be moved and the space between the upper and lower rolling rolls 51 and 52 had to be widened, it took a very long time to be able to remove the sandwiched hand.

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

Therefore, in order to eliminate the danger in the noodle strip rolling machine as described above, the present invention is designed so that even if the hands are mistakenly caught between the upper and lower rolling rolls, The purpose of the present invention is to provide an improved noodle strip rolling machine so that it is possible to quickly pull out between rolling rolls.
