Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a rotary cutting device, and more particularly to a rotary cutting device capable of forming a soft material to be rolled such as a noodle band into a triangular cross-sectional shape.
[0002]
[Prior art]
Conventionally, when craftsmen manually produce noodles such as buckwheat and udon, the cross-sectional shape of the noodle has been a rhombus or a parallelogram. In the case of hand-cooking, as a result of manufacturing the noodles in such a shape, the way of boil-up differs between the acute angle part and the obtuse angle part of the cross section, and the shape, the touch, the taste, etc. are varied.
[0003]
On the other hand, when manufacturing noodles such as udon and soba using a noodle making machine, a strip-shaped noodle strip having a predetermined thickness is manufactured, and the noodles are manufactured by cutting the strip in the longitudinal direction using a rotary cutting device. It was. For example, the rotary cutting machine is configured to cut two noodle strips by meshing two cutting blade rolls having a shape in which two types of cylindrical cutting blades having the same thickness and two large and small radii are alternately stacked. In the rotary cutter having such a configuration, the noodle strip is cut perpendicular to the surface, and the cross-sectional shape of the noodle is rectangular.
[0004]
[Problems to be solved by the invention]
In the conventional rotary cutting apparatus as described above, the cross-sectional shape of the noodles can only be cut into a rectangle, and there is a problem that the shape, touch, taste and the like are poor.
The present invention solves the problems of the prior art as described above, and provides a rotary cutting apparatus capable of cutting and forming a soft material to be rolled such as a noodle band into a triangular cross-sectional shape. Objective.
[0005]
[Means for Solving the Problems]
The present invention relates to a rotary cutting apparatus that encloses and cuts a material to be cut, so that a plurality of triangular spaces are formed between the two rotary rolls on a cross section passing through the axes of the two rotary rolls. The rotary roll and the second rotary roll are rotatably supported at a predetermined interval.
[0006]
According to the present invention, when a noodle strip or the like is cut by a rotary cutting device, the cross section is compressed into a triangular space by two rolls to form a noodle having a triangular cross section.

BEST MODE FOR CARRYING OUT THE INVENTION
FIG. 1 is a front view (right) showing the structure of the rotary cutting apparatus 1 of the present invention (right) and a cross-sectional view (left) in the AA ′ portion. An upper roll 2 and a lower roll 3 having the same shape are mounted on the two shafts 4 and 5 that are rotatably supported by the frame of the rotary cutting device 1. When viewed from the axial direction, each of the rolls 2 and 3 has a cylindrical or frustoconical exposed circular side surface part of each rotating roll, and a cylindrical or frustoconical exposed circular side surface of the opposing rotating roll. Two rolls are arranged at a predetermined interval so as to overlap a part.
[0008]
An upper roll demon gear (not shown) is fixed to the shaft 4 of the upper roll 2, and a lower roll demon gear and a chain gear (not shown) meshed with the upper roll demon gear are fixed to the shaft 5 of the lower roll 3. Has been. A chain gear (not shown) is connected by a chain to a chain drive gear mounted on a shaft of a motor with a speed reducer (not shown).
[0009]
In such a configuration, when the motor rotates, power is transmitted to the upper and lower rolls 2 and 3 via the chain and each gear, and the upper and lower rolls rotate in opposite directions. When the noodle band is inserted there, the noodle band is cut at the cutting edge portions on both sides of the frustoconical shape having a large radius between the upper and lower rolls 2 and 3. Note that the shaft 4 of the upper roll 2 is supported by the frame via an interval adjusting member (not shown) that is slidable in the horizontal direction with respect to the frame 1. The gap between the rolls 2 and 3 can be adjusted.
[0010]
The roll 2 is a roll having a shape in which two types of frustoconical shapes having different radii are alternately stacked in opposite directions in the axial direction, and the roll 3 is also a shape in which two types of frustoconical shapes having different radii are alternately stacked in the axial direction. A gap between adjacent frustoconical shapes having a large shape is arranged so as to be fitted to the frustoconical shape having a large radius of the opposed rotating roll. Each roll is manufactured, for example, by cutting a cylindrical material. The frustoconical shape refers to a solid shape formed by rotating a cone into a shape perpendicular to the axis or rotating a symmetrical trapezoid around a vertical center.
[0011]
FIG. 2 is an enlarged cross-sectional view of the first embodiment of the cutting blade portion of the roll. FIG. 3 is an enlarged cross-sectional view of the cutting blade portion when the noodle strip is cut with two rolls of the first embodiment. Between the frustoconical cutting blade with a large radius of one roll and the corresponding frustoconical shape with a small radius of the other roll, there is a triangular gap with one side being about the thickness of the noodle strip. As shown in FIG. 3, the cut noodle strip 10 is shaped into a triangle when passing through this gap. The cutting blades shown in FIGS. 2 and 3 have a structure in which the frustoconical side surfaces 6 and 7 slide with each other.
[0012]
FIG. 4 is an enlarged cross-sectional view of a second embodiment of the cutting blade portion of the roll. FIG. 5 is an enlarged cross-sectional view of the cutting blade portion when the noodle strip is cut with two rolls of the second embodiment. Between the cylindrical cutting blade with a large radius of one roll and the corresponding frustoconical shape with a small radius, there is a right-angled triangular gap with one side about the thickness of the noodle strip. As shown in FIG. 5, the cut noodle strip 10 is shaped into a triangle when passing through this gap. In the cutting blades shown in FIGS. 4 and 5, the areas of the sliding (overlapping) frustoconical side surfaces 6 and 7 are smaller than those of the first embodiment and are the same on all the side surfaces.
[0013]
FIG. 6 is an enlarged cross-sectional view of a third embodiment of the cutting blade portion of the roll. FIG. 7 is an enlarged cross-sectional view of the cutting blade portion when the noodle strip is cut with two rolls of the third embodiment. A triangle whose side is about the thickness of a noodle band between a cutting blade having a shape of two truncated cones with a large radius on one roll and a corresponding cylindrical shape with a small radius on the other side As shown in FIG. 7, the cut noodle strip 10 is shaped into a triangle when passing through this gap. In the cutting blades shown in FIGS. 6 and 7, the areas of the sliding (overlapping) frustoconical side surfaces 6 and 7 are smaller than those of the first embodiment and are the same on all side surfaces. Further, the circumferences of the opposed cylindrical and truncated cones can be made substantially the same.
[0014]
Although the embodiments have been described above, the following modifications may be considered in the present invention. Although the roll is made of metal, for example, the surface may be fluorinated so that the noodle band can be easily separated. In the first and second embodiments, the tilt directions of the frustoconical shape are all the same direction. However, for example, if the roll is made symmetrical in the axial direction by reversing the tilt direction at the central portion, it is applied in the axial direction when cutting. Power is reduced more.
In the embodiment, an example in which the thicknesses of the truncated cone-shaped cutting blades are all uniform is disclosed, but the thickness of actual hand-made noodles is slightly changed. Therefore, also in this invention, you may change the thickness of a cutting blade, and it can change to the width | variety of noodles in that way. The width type may be 3 or more, and what width is to be manufactured at what ratio, and what width is assigned to which position of the roll is also arbitrary.
The present invention is not limited to noodle strips and can be applied to any material that can be cut and compressed to be shaped.
