Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rolling apparatus, and more particularly, to a rolling apparatus capable of giving a change in thickness when rolling a material to be rolled such as a noodle band.

[0002]

2. Description of the Related Art Conventionally, when noodles such as buckwheat noodles and udon are hand-manufactured by a craftsman, the dough is stretched with a rolling pin, and the folded noodle band is cut with a kitchen knife. Therefore, the thickness of the noodles was slightly changed. In the case of hand-made noodles, as a result of the noodles being manufactured in this manner, boiled portions are differently boiled at different thicknesses, and the shape, tongue, taste and the like are varied.

On the other hand, when noodles such as udon and buckwheat are manufactured by a noodle-making machine, a band-shaped noodle band having a predetermined thickness is manufactured using a rolling device using round rollers. The noodles were cut in the longitudinal direction by a rotary cutting device.

[0004]

In the conventional rolling apparatus as described above, since the rollers are perfectly circular, the thickness of the noodles is all uniform, and the change is less than that of hand-made noodles. There was a problem.

The present invention has been made to solve the above-mentioned problems of the prior art, and to provide a rolling apparatus capable of giving a change in thickness when rolling a material to be rolled such as a noodle band. Aim.

[0006]

According to the present invention, there is provided a rolling apparatus for rolling a material to be rolled between two rollers, wherein at least one of a depressed portion and a raised portion is formed in a circumferential direction on at least one roller surface. It is characterized in that a plurality are provided. Further, at least one of a depression and a protrusion is provided in the circumferential direction of both roller surfaces, respectively, and a change pattern of the thickness of the material to be rolled is changed by changing a rotational phase difference between both rollers. Another feature is that it can be changed.

[0007] By rolling the noodle band using the rolling device of the present invention, the thickness in the length direction of the noodle band can be changed.

[0008]

FIG. 2 is a side view (a) and a front view (b) showing the structure of a rolling mill according to the present invention. An upper roller 4 and a lower roller 5 are mounted on two shafts rotatably supported by a frame of a rolling device. The structure of the roller surface will be described later. The upper roller 4 is fixed to the shaft of the upper roller 4.
The lower roller wheel 2 meshing with the upper roller wheel 1 and the chain gear are fixed to the shaft.

Gears having the same radius and the same number of teeth are used for the upper roller wheel 1 and the lower roller wheel 2. At least one of the two gears 1 and 2 is configured so that the roller and the demon gear can be set and fixed at an arbitrary phase difference. The phase difference can be set arbitrarily. The chain gear is connected by a chain 3 to a chain drive gear mounted on the shaft of a motor 6 with a reduction gear.

In such a configuration, when the motor 6 rotates, the power is transmitted to the upper and lower rollers 4 and 5 via the chain and the respective gears, and the upper and lower rollers rotate synchronously in opposite directions. For example, as shown by an arrow in FIG. 2A, the noodle belt is supplied from the upper left side of the apparatus, and is output from the lower right side to the next apparatus or a belt conveyor.
Note that the shaft of the upper roller 4 is supported by the frame via an interval adjusting member 8 slidable in the horizontal direction with respect to the frame, and by operating the adjusting handle 9,
The gap between the two rollers can be adjusted.

FIG. 1 is a sectional view showing the structure of the roller of the present invention. The roller 4 (5) is rotatably fixed to the frame by the shafts at both ends, and the surface of the roller 4 is partially cut. For example, the roller is cut such that the radius becomes R around a point P1 eccentric by a distance L from the center Q of the roller 4. Let the radius of the roller be r, point QP
If the distance between 1 is L, then R = r + L−h. h is the maximum thickness to be cut, for example, about several millimeters. L is experimentally determined so that the range of the depression is optimal.

As a result, in the range of the angle θ as viewed from the center Q of the roller 4 in FIG. 1, the surface of the roller is cut by the maximum thickness h to form a depression. Although the depression is not actually depressed, the distance from the roller center Q is shorter than the original round roller surface (indicated by a dotted line in FIG. 1). In this sense, it is called a depression. In the embodiment shown in FIG. 1, the entire roller is equally divided into four equal parts, and a depressed portion having a center eccentric with P1 to P4 is formed at each location.

FIG. 3 is an explanatory view in which the gap between the roller 4 and the roller 5 is developed for one round of the roller. FIG. 3A shows a case where a roller 4 having depressions formed at four places as shown in FIG. 1 is used as the roller 4, and a normal round roller is used as the roller 5. As shown, in the four depressions, the distance between the two rollers is large. Therefore, when the noodle band is rolled using such a roller, the length of the noodle band in the longitudinal direction increases four times corresponding to the depressed portion during one round of the roller. The increase (h) in the gap (thickness) is exaggerated.

FIG. 3 (b) shows the gap of the roller 4 and the roller 5 when the rollers as shown in FIG. 1 are used so that the depressions face each other (the phase difference is 0 degree). It is a development view. FIG. 3C is a development view of a gap when the roller as shown in FIG. 1 is used for both the roller 4 and the roller 5 and the depressed portion is mounted so that the phase thereof is shifted by 45 degrees. FIG. 3D is a developed view of the gap when the depression is mounted so that the phase of the depression is shifted by 30 degrees.

As shown in FIG. 3, even when rollers having the same depression are used, the change pattern of the gap between the rollers differs depending on the phase difference between the upper and lower rollers. Therefore, by adjusting the engagement phase of the demon gears 1 and 2, the thickness of the noodle belt can be made to have a desired change pattern.

Although the embodiments have been described above, the present invention may have the following modifications. In the embodiment, the example in which the depression is provided on the roller is disclosed. However, a protrusion may be provided instead of or together with the depression. In the case of a raised portion, the thickness of the noodles is reduced by the height of the raised portion.
Further, the shape, arrangement and number of the depressions may be changed within one roller or between upper and lower rollers. Further, the diameter of the upper and lower rollers may be changed. When the diameter of the roller is changed, the phase difference between the two rollers changes for each rotation, and various thickness change patterns occur.

As a method of forming a depression in the roller,
By cutting so as not to exceed a certain distance from the eccentric center point, an example was disclosed in which the shape of the corresponding gap became an arc shape. The depression may be cut such that The rolling device of the present invention is not limited to the noodle belt, but is applicable to rolling of any soft material to be rolled.

[0018]

As described above, according to the present invention, when rolling a material to be rolled such as a noodle band, it is possible to change the thickness, and by using a machine, the thickness is closer to hand-made noodles. There is an effect that noodles having a structure can be manufactured.
