Description

[Detailed Description of the Invention] This invention... Regarding noodle strip rolling equipment. In particular, the dough is kneaded by mixing flour, salt, etc. and rolled through multiple sets of rolling rollers to form noodle sheets. After passing through the last rolling roller, the dough is formed into noodle sheets with a predetermined thickness. The detection mechanism detects whether or not the thickness of the noodle strip is different from a predetermined thickness. The adjustment drive device is operated according to the result, thereby adjusting the rolling thickness of the rolling portion of each rolling roller, thereby automatically adjusting the rolling ratio for pressing the noodle strip of each rolling roller, and further, The rolling force of each rolling roller is adjusted and set to an average value, so that the thickness of the noodle strip is always maintained at a predetermined dimension, and stable noodle strip rolling is performed.

in general. A noodle rolling machine is made up of several pairs of rolling rollers arranged in a row, and the dough, which has been kneaded with flour, etc., is passed through these rolling rollers and gradually rolled to form it into the desired thickness. After this, the noodle strip is introduced into a cutter or the like and cut into the desired width and length.

In a conventional noodle strip rolling machine, several rolling rollers having different roller diameters are arranged in the direction in which the noodle strip travels in descending order of roller diameter.

Although the roller diameter ratio and circumferential speed ratio of each rolling roller are set in advance, the rolling thickness of the rolling portion of each rolling roller can be adjusted individually for each rolling roller. By operating a provided manual adjustment handle, the gap between the two opposing rollers constituting the rolling roller was adjusted for each rolling roller.

For this reason, the rolling ratio of the noodle strip varies depending on each rolling roller, resulting in a drawback that the rolling force acting on each rolling roller differs.

Furthermore, since the rolling thickness of each rolling roller must be adjusted individually for each rolling roller, the adjustment work is troublesome.

On the other hand, dough made by kneading wheat flour etc. is not always mixed in a constant ratio, and is particularly affected by the atmosphere, making it difficult to maintain a constant moisture content. It is difficult to make the belt uniform in thickness.

For this reason, the influence of the thickness of the noodle strips on the final product has caused many problems, such as variations in product weight and thickness.

This inventor has come up with this invention in view of such problems.

That is, the purpose of the present invention is to detect the thickness of the noodle strip that has passed the last rolling roller and compare whether or not the thickness is within a desired dimension. An object of the present invention is to provide a noodle strip rolling device that can automatically adjust the movement of each rolling roller while maintaining a series of rolling ratios based on a preset rolling ratio.
A further object of the present invention is to be able to proportionally set and change the rolling amount of each rolling roller that rolls the noodle strips to their respective dimensions, and to be able to roll the noodle strips stably from beginning to end.
To provide a noodle strip rolling device capable of producing noodle strips having a somewhat uniform thickness.

Behind the last rolling roller 1e in the direction of movement of the noodle strip 2.
A detection mechanism 5 is provided to detect the thickness of the noodle strip 2 rolled by the last rolling roller 1e.

The detection mechanism 5 is comprised of a pair of detection rollers, a lower roller 21 and an upper roller 22, which sandwich the noodle band 2 from above and below, as shown in an enlarged view in FIG.

The lower roller 21 has its position fixed and can only rotate freely at a predetermined position. Upper roller 22
is supported by a balance-shaped arm 23, and is configured to be able to move up and down according to the thickness of the noodle strip 2.

That is, the upper roller 22 is pivotally connected to one end of the arm 23, and a balance weight 25 is provided at the other end of the arm 23, sandwiching a pivot point 24 provided halfway in the longitudinal direction.

Furthermore, a scale 26 is installed upright on the arm 23.

This scale 26 has a reference point 27 as shown in FIG.
will be established.

The scale 26 is inserted into the annular sensor head 28.

The sensor head 28 includes a reference value setting section 29 for comparing and contrasting the position of the reference point 27 in the vertical direction of the annular inner peripheral surface facing the scale 26, and above and below the reference value setting section 29, An upper limit detection section 30 and a lower limit detection section 31 are provided.

For example, when rolling and forming noodle strips 2 with a thickness of 1 mm, if the tolerance value for the thickness is ±0.1 mm, the reference value setting section 29 is set to 1 mm, and the upper limit detection section 30 is set to 1.1 mm. At the same time, the lower limit detection section 31 is set to 0.9 mm.

The sensor head 28 communicates with a sensor 32.

This sensor 32 detects the noodle strip 2 detected by the sensor head 28.
Converts changes in thickness into a constant electrical signal.

Further, the sensor 32 is connected to the command device 6.

The command device 6 is electrically connected to the detection mechanism 5 and the adjustment drive device 4, and constitutes a control circuit 6c.

Then, according to the thickness of the noodle strip detected by the detection mechanism 5, a command is given to adjust the rolling thickness of each of the rolling rollers 1a to 1e.

This command device 6 consists of a calculation section 6a and a drive section 6b.

The calculation unit 6a performs calculation based on the electric signal input from the sensor 32, and calculates the calculation based on the electric signal inputted from the sensor 32, and applies the calculation to the drive unit 6b according to the detected amount.
into a signal for operation.

On the other hand, the drive unit 6b selects and outputs a forward rotation signal or a reverse rotation signal for rotating the adjustment drive device 4 in the forward or reverse direction from the signal input from the calculation unit 6a.

In this case, the amount of movement of each of the rolling rollers 1a to 1e operated by the command from the command device 6 is such that the movement rate decreases in proportion from the first rolling roller 1a to the last rolling roller 1e in the direction of movement of the noodle strip 2. Set to .

For example, for each adjustment and one rotation of the drive device 4, the rotation rate of the handle (not shown) for moving the opposing roller 8 forward and backward toward the drive roller 7 is set to 1 for the first rolling roller 1a = 1 rotation, second rolling roller 1b = 1/2 rotation, third rolling roller 1c = 1/3 rotation, fourth rolling roller 1
d=1/4 rotation. The fifth rolling roller 1e is set to rotate by 1/5 rotation each time.

The command device 6 is communicated with each of the adjustment drive devices 4 .

next. The operation of this device will be explained.

The dough kneaded with flour, salt, etc. is passed through the first rolling roller 1a.
The rolling rollers 1e are introduced sequentially from 5 to 5 rolling rollers 1e, and the noodle strips 2 are rolled so as to become successively thinner.

Then, the thickness of the noodle strip 2 that has passed the last rolling roller 1e is detected by the detection mechanism 5.

That is, if the noodle strip 2 at the position of the detection roller has a predetermined size, the upper roller 22 maintains its posture at the reference position, so the scale 26 erected on the arm 23 of the upper roller 22 also moves in the same manner. Hold that posture.

Since the scale 26 does not move up or down relative to the sensor head 28, no signal is sent to the sensor 32.

Therefore, since no signal is sent from the command device 6, each adjusting drive device 4... does not operate, and each rolling roller 1a to 1
The rolling thickness of e is also kept constant.

On the other hand, if it is detected that the rolled noodle strip 2 is thicker than a predetermined thickness due to the amount of moisture contained, etc., in other words, the scale 26 rises as the upper roller 22 rises, and the scale 26 is attached to the scale. The reference point 27 is the sensor head 28.
When the upper limit detection unit 30 is reached, the upper limit detection unit 30
A signal is sent from the sensor 32 to the sensor 32.

Next, the signal from the sensor 32 is received by the calculation unit 6a of the command device 6, and the amount of change in the thickness of the noodle strip 2 is calculated, and a signal corresponding to the magnitude of the change is sent to the drive unit 6b.

, the drive section 6b receives the signal from the calculation section 6a and sends the signal to each adjustment drive device 4.
... is rotated a predetermined number of times.

In this case, the amount of movement of each rolling roller 1a to 1e is set in advance. Each of the rolling rollers 1a to 1e is set to move based on a preset rolling ratio, and operates in series according to commands from the command device 6.

Further, in contrast to the above, the same operation is performed when the lower limit detection section 31 detects the amount of change in the thickness of the noodle strip 2.

However, the signal sent from the drive unit 6b of the command device 6 is
The direction of rotation of each adjusting drive 4 . . . rotated by said signal sends a signal to rotate said adjusting drive 4 in a direction opposite to said one.

Thus, while the thickness of the noodle strip 2 gradually decreases during rolling, the length in the longitudinal direction increases, so the circumferential speed of each of the rolling rollers 1a to 1e is set to become faster as the rolling rollers are located at the rear. be done.

For this reason. Since the diameter of the rolling rollers 1a is made smaller as the rolling rollers 1a are located at the rear due to centrifugal force, etc., the rolling thickness of the rolling section 3 is also set to be smaller as the rolling rollers are located at the rear.

In view of the characteristics of such a rolling apparatus, when adjusting the gap between the rolling sections 3 of each of the rolling rollers 1a to 1e, it is preferable that the amount of gap adjustment be made smaller as the rolling rollers are located at the rear. The above objectives are fully satisfied, and the adjustment can be made automatically.

In this embodiment, the sensor head 28 is provided with a pair of detecting sections 30 and 31 above and below the reference value setting section 29, but a plurality of detecting sections may be provided above and below. Of course.

In this case. The sensor head 28 sends as many signals as the reference points 27 have passed.

moreover. The structure of the detection mechanism 5 as a whole is not limited to the structure shown in this embodiment.

As is clear from the above, according to the present invention, the thickness of the noodle strip that has passed the last rolling roller is automatically detected, and a constant comparison is made to see whether the thickness is within a desired dimension. If it is detected that the thickness of the noodle strip is other than the desired size, the noodle strip is rolled sequentially from the first rolling roller to the last rolling roller in the traveling direction of the noodle strip based on a preset rolling ratio. Each rolling roller was set by decreasing the amount of change in the gap between the parts. It is possible to maintain a series of rolling ratios and automatically adjust the movement according to the thickness of the noodle strips detected by the detection mechanism, and it is possible to manufacture noodle strips that always have a constant thickness.

Furthermore, according to this invention. The rolling amount of each rolling roller that rolls the noodle strips to their respective dimensions can be set and changed proportionally, and the noodle strips can be rolled stably from beginning to end without sagging between the rolling rolls. can.
