Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a food cutting machine for cutting a food to be cut by rotating a rotary disk having a planer blade and bringing the food to be cut into contact with the rotary disk.

[0002]

2. Description of the Related Art For example, in restaurants such as soba restaurants and Japanese restaurants,
In many cases, shavings for soup stock are made by hand. The conventional bonito-brush scraper is equipped with a cutting member that is a carpenter's tool that has the planer turned inside out.By pressing the bonito-bushi on the surface of this cutting member and moving it back and forth, the bonito-brush is scraped by the planer blade. You get a sharp cut.

[0003]

However, the conventional bonito shaving machine requires labor to move the bonito shavings back and forth by hand, and it takes a lot of time and labor to make a large amount of shavings. It was Further, the conventional apparatus for automatically manufacturing shavings has only a large size for a shavings manufacturing factory, and is not suitable for a small-scale restaurant. In addition, conventionally, a small cutter device for slicing or finely chopping foods such as vegetables and meat has been provided, but the blade of the cutter is a thin metal plate, and foods that are hard such as bonito flakes can be cut to 0.1 mm or less. It is impossible to cut to the thinness. In addition, other ingredients such as dried kelp and dried shiitake mushrooms are often used for the soup stock. When making the soup stock, these ingredients are cut into pieces by hand and used. For this reason, it took a lot of time and labor. Under such circumstances, there has been a long-felt demand for a small and convenient device that can easily manufacture a scraper by using mechanical power and can finely cut other foods.

[0004]

In order to solve the above-mentioned problems, the present invention is designed to rotate a rotary disk having a planer blade by a rotary power source, and bring food to be cut into contact with the rotary disk to cut the object to be cut. It is characterized by cutting food. Furthermore, a concave groove is provided on the cutting surface of the rotating disk, which comes into contact with the food to be cut. As a result, the friction between the food to be cut and the cutting surface of the rotary disk is reduced, so that good cutting can be performed and the device can be downsized.

Further, a contact member for contacting the food to be cut with the cutting surface of the rotary disk from a direction inclined with respect to the cutting surface of the rotary disk is provided, and the cutting surface of the rotary disk of the contact member is provided. The inclination angle of the tip surface near the position closest to the cutting surface of the rotary disk may be increased. As a result, the food to be cut is extruded along the inclined surface onto the cutting surface of the rotating disk, so that the food to be cut is entirely cut and no uncut residue occurs.

Alternatively, a plurality of planer blades may be provided on the rotary disk, and notches may be formed at the cutting edges of these planer blades. As a result, the cut width of the food to be cut can be reduced, and the friction between the planer blade and the food to be cut can be reduced.

Further, an engaged portion is exposed at the tip of the output shaft of the rotary power source, and an engaging member is engaged with the engaged portion when the driving of the rotary power source is stopped. Alternatively, the rotating disk may be manually rotated in the reverse rotation direction. As a result, when the planer blade bites into the food to be cut and the rotation of the rotating disk stops (locks), the engaging member is engaged with the engaged portion and the rotating disk is rotated in the opposite direction to lock. By releasing it, the biting of the planer blade can be easily released, and cutting can be performed immediately thereafter.

The slip stopper 21 is an elastic body, and also has a role as a cushioning material that absorbs vibration generated from the electric motor 2 and the rotating disk 10.

FIG. 3 is a sectional view taken along line BB in FIG. An output shaft 22 is inserted in the front-rear direction at the center of the output shaft housing 11. The output shaft is rotatably supported in the output shaft housing 11 via bearings 23 and 24. Output shaft 2
The rear end of 2 is connected to the rotary shaft 2a of the electric motor 2 by a joint 25, whereby the output shaft 22 outputs the rotary torque of the electric motor 2. The rotating disk 10 is fixed to the front end of the output shaft 22 by a collet 26 and a nut 27. The rear surface of the rotating disk 10 is the cutting surface 1
It is 0a. A taper hole 10b is formed at the center of the rotary disk 10 and expands forward. The front end of the output shaft 22 is inserted into the taper hole 10b.

The collet 26 has a taper portion 26a which contracts rearward, and the taper portion 26a is formed in the taper hole 1.
It fits in 0b. As shown in FIG. 5, the taper portion 26a of the collet 26 is formed with four slits 26b in the cross direction. Therefore, by tightening the nut 27, the gap between the slits 26b becomes narrower as the tapered portion 26a of the collet 26 enters the tapered hole 10b. As a result, the inner diameter of the collet 26 becomes smaller, and the outer circumference of the output shaft 22 is strongly clamped by the tapered portion 26a. Further, the outer circumference of the tapered portion 26a is pressed against the inner circumference of the tapered hole 10b of the rotary disk 10. As a result, the rotary disk 10 is pivotally fixed to the output shaft 22.

The tip of the output shaft 22 is exposed and protrudes forward of the nut 27, and an engaged portion 22a in the shape of a hexagonal nut is provided. Further, a through hole 5a is formed in the lid 5 at a position where an extension line of the axis of the output shaft 22 intersects with the lid 5, and the engaged portion 22a can be seen through the through hole 5a. Then, the electric motor 2 and the food holding unit 1
2 is arranged on the cutting surface 10a side of the rotating disk, and the engaged portion 22a is arranged on the opposite side to the cutting surface 10a.

The material of the rotary disk 10 is aluminum, and the entire surface is subjected to Kashima Coat processing (trade name of Miyaki Co., Ltd. (Kurematsu Town, Hamamatsu City, Shizuoka Prefecture)). Kashima coat treatment is a hard anodization treatment of aluminum to form a hard alumite layer coating, and after the secondary electrolysis of this alumite layer in ammonium tetrathiomolybdate solution, it is uniformly disulfided in the oxide coating. It is a surface treatment that deposits molybdenum from the bottom. This Kashima coat treatment makes the surface of aluminum hard and smooth, and also enhances the touch resistance. Further, since the crystal of molybdenum dioxide significantly improves the lubricity of the coating, the lubricity that can withstand sliding friction without oil supply is obtained.
Further, this coating is lightweight and does not impair the lightweightness of aluminum.

FIG. 4 is a front view of the cutting machine 1 when the lid 5 is removed. The rotating disk 10 has 3 at intervals of 120 degrees.
One through groove 28, 29, 30 is formed. These through grooves 28 to 30 are formed so as to be linear in the radial direction of the rotating disk 10. As shown in cross section in FIG. 6, the through grooves 28, 29, 30 have two inclined surfaces 34, 35 facing each other. Plane blades 31, 32, and 33 are attached to one inclined surface 35.
Cutting edges 31a, 32a, 33 of the planer blades 31, 32, 33
“A” appears from the opening 36 on the cutting surface 10a side of the rotating disk 10. A pressing plate 38 is placed on the upper surfaces of the planer blades 31, 32, 33, and the inclined surface 3 is formed by a hexagon socket bolt 39.
5 is fixed. The side of the pressing plate 38 on the side of the opening 36 has an inclined surface 38a, and the cutting piece has this inclined surface 38a.
Is discharged from the through grooves 28, 29, 30 along the. The planer blades 31 to 33 are made of steel, for example, and have blade edges 41 to 4
3 is tempered.

As shown in FIG. 7, a spiral groove 40 is formed on the cutting surface 10a of the rotary disk 10.
The groove 40 has a spiral shape that spreads clockwise from the center when the rotating disk 10 rotates in the direction A in the drawing when cutting food. When the rotary disk 10 rotates in the direction opposite to the A direction in the drawing when cutting food, the concave groove 40 is formed into a spiral that extends counterclockwise from the center. That is, the concave groove 40 is formed in a direction substantially along the cutting (moving) direction of the food to be cut. As a result, with the rotation of the rotary disc 10, a force pulling toward the center of the rotary disc 10 acts on the food to be cut that contacts the cutting surface 10a.

As shown in FIG. 8, the planer blades 31, 3 are
The notches 44, 4 are provided on the blade edges 41, 42, 43 of 2, 33.
5, 46 are formed. Planer blades 31, 32, 33

Are formed with elliptical holes 37, 37, ...

2. Operation and Action Next, the operation and action of the cutting machine 1 configured as described above will be described. When the switch 19 is turned on, the electric motor 2
Rotates, and the rotation torque of the electric motor 2 causes the output shaft 22 to rotate.
Is transmitted to Therefore, the rotating disk 10 pivotally attached to the output shaft 22 rotates in a fixed direction. Since the rotating disk 10 is made of aluminum, it is lightweight, and therefore the electric motor 2
High-speed rotation is possible even if the capacity is small. Then, the food to be cut is put into the food holding unit 12. For example, a case where a bonito flakes are cut to produce shavings will be described. As shown in FIG. 9, the handle 8c is pulled rearward to insert the bonito knot 51 between the contact member 8 and the rotary disk 10. Since the abutment member 8 is biased by the spring 17, the bonito 51 is rotated by the abutment member 8 into the rotating disk 10.
Is pressed against the cutting surface 10a. Therefore, the bonito flakes 51 are cut by the planer blades 31 to 33 provided on the rotary disk 10. Katsuobushi 51 carved with planer blades 31-33
The thin flakes become the shavings 52 and are sent to the front surface of the rotating disk 10, and are discharged downward from the discharge port 4a through the space between the disk accommodating portion 4 and the lid 5. The saucer 4 is provided under the discharge port 4a.
If 7 is arranged, shavings 52 are deposited in the tray 47. In addition, the planer blades 31 to 33 are hard bonito flakes 51.
Thin shavings 5 that can be used to cut a workpiece and that is 1 mm or less
2 can be mass produced at high speed.

The bonito knot 51 and the cutting surface 10a are pressed against the cutting surface 10a and the rotating disk 10 rotates at high speed.
A frictional force is generated between and. However, since the spiral concave groove 40 is formed on the cutting surface 10a of the rotary disk 10 as described above, the area where the bonito knuckle 51 contacts the cutting surface 10a is reduced, and the friction can be reduced. Moreover, since the surface of the rotary disk 10 is subjected to the Kashima coating as described above, the frictional force is extremely small. Further, since the friction is small, the temperature rise of the rotating disk 10 can be suppressed. Further, aluminum, which has a higher heat radiation efficiency than iron, is used for the rotary disc 10, and the groove 40 generates an air flow to enhance the heat radiation effect, thereby suppressing the temperature rise of the rotary disc 10. it can. As a result, it is possible to prevent deterioration of the food to be cut due to high temperature, and to prevent the food to be cut from melting and adhering to the rotating disk 10 due to high temperature.

The rotation of the rotary disk 10 causes the bonito flakes 5
A centrifugal force acts on 1 to move the bonito flakes 51 in the circumferential direction of the rotating disk 10. The rotational torque generated by the rotating disk 10 with respect to the bonito knot 51 is larger as it is closer to the center of rotation and smaller as it is farther from the center of rotation due to the relationship of the rotation moment. Since the force for cutting the bonito flakes 51 is proportional to the rotational torque, the force for cutting the bonito flakes 51 becomes small at a position far from the center of rotation. Further, the frictional force between the bonito knot 51 and the cutting surface 10a acts as a braking force of the rotating disk 10, and this braking force becomes larger as it is farther from the center of rotation due to the relationship of the rotation moment. Therefore, when the bonito flakes 51 are cut at a position far from the center of rotation, the braking force acting on the rotary disc 10 becomes large, which may reduce the rotational speed of the rotary disc 10 and reduce the cutting performance. However, in this embodiment, as described above, the concave groove 40 is formed in a spiral shape, and the rotary disk 10 is rotated in the direction in which the point on the spiral shape moves to the center. As a result, a force pulling toward the center of the rotary disc 10 acts on the bonito joints 51 abutting on the cutting surface 10a as the rotary disc 10 rotates, whereby the bonito joints 51 can be cut at a position close to the center of rotation. Therefore, the force for cutting the bonito flakes 51 can be increased, and the braking force acting on the rotating disk 10 can be reduced.

Further, as described above, the cutting widths of the bonito flakes 51 are divided by the notches 41 to 43 because the notches 44 to 46 are formed at different positions on the cutting edges 41 to 43. Therefore, the width of the shavings 52 does not become too wide, and the shavings 52 having a width suitable for cooking can be obtained. Also,
By providing the notches 44 to 46, the cutting edges 41 to 43
The contact length of the bonito with the bonito flakes 51 is reduced, and the friction can be reduced accordingly. Further, since the cutouts 44 to 46 are formed at different positions, even when one planer blade 31 cuts the bonito knot 51, a convex streak is generated on the cut surface of the bonito knot 51 by the notch 41. , The other planing blades 32 and 33 scrape this convex streak. Therefore, the convex streak generated by the notches 44 to 46 does not grow, and the cutting operation is smoothly performed.

Then, the cutting of the bonito flakes 51 progresses, and the bonito flakes 51
The contact member 8 rotates forward due to the urging force of the spring 17 as the pressure becomes smaller, and the bonito knot 51 is constantly pressed against the cutting surface 10a. Therefore, after the bonito flakes 51 are put into the food holding unit 12, the bonito flakes 51 are automatically cut without touching the handle 8c. Here, assuming that there is no convex portion 8e of the contact member 8, when the cutting of the bonito knot 51 progresses, the lower end of the bonito knot 51 forms an angle between the front surface of the abutment member 8 and the cutting surface 10a of the rotary disk 10. They come to the same angle. For this reason, when the angle formed between the front surface of the contact member 8 and the cutting surface 10a becomes small, the angle at the lower end of the bonito knot 51 also becomes small, and the lower end of the bonito knot 51 becomes prone to cracking. If the lower end of the bonito flakes 51 cracks, not only the production amount of shavings will decrease, but also
The broken pieces of the dried bonito clog in the gap between the rotary disk 10 and the disk accommodating portion 4, which causes the rotation of the rotary disk 10 to stop. On the other hand, in this embodiment, the lower end of the bonito knot 51 is pushed out along the inclined surface 8f of the convex portion 8e. As a result, the angle of the lower end of the bonito knot 51 does not decrease, and the lower end of the bonito knot 51 can be prevented from cracking during cutting of the bonito knot 51.

When all the bonito pieces 51 are cut, the upper part of the front surface of the contact member 8 contacts the stopper portion 4b as shown in FIG. 1 to prevent the contact member 8 from rotating forward. Therefore, the front surface of the contact member 8 does not contact the cutting surface 10a. If one bonito flakes 51 are cut down,
By pulling the handle 8c backward and inserting the next bonito flakes, it is possible to continuously produce the scraped flakes. When the switch 19 is turned off, the electric motor 2 is stopped and the rotation of the rotary disk 10 is also stopped.

As described above, the cutting machine 1 of this embodiment can cut food to be cut easily and at high speed. Also,
Since the rotation shaft 2a of the electric motor 2 is projected out of the center and the food holding portion 12 is arranged on the cutting surface 10a side of the rotating disk like the electric motor 2, the whole shape can be made compact. . Further, since the food to be cut is inserted into the food holding portion 12 from above, there is no obstruction even if another object is placed beside the cutting machine 1, and the installation space is small. Further, by disposing the rotating disk 10 in front of the supporting column 13 of the frame 3 and by arranging the electric motor 2 and the food holding unit 12 in the rear thereof, the balance between the front and rear is balanced, and the rotating disk is formed by one supporting column 13. 1
0, the electric motor 2, the food holding portion 12, etc. can be supported and stable. Further, since the rotary disc 10 is pivotally attached to the output shaft 22 by using the collet 26, the rotary disc 10 can be attached to and detached from the output shaft 22 by only attaching and detaching one nut 27. The number of parts can be reduced as compared with the case of fixing with a plurality of bolts.

3. Adjusting the amount of protrusion of the cutting edge of the planer blade The thickness of the shavings 52 is determined by the amount of protrusion of the cutting edges 41 to 43 of the planer blade from the cutting surface 10a of the rotary disk 10. When manufacturing a shaving node, since the amount of protrusion of the blade edges 41 to 43 is several microns to several hundreds of microns, it is extremely difficult to strike and adjust the blade like a carpenter's tool. Therefore, the cutting machine 1 of the present embodiment is configured so that the protrusion amount of the cutting edge can be easily adjusted. As shown in FIG. 6, the planer blades 31, 32, 33 are provided with oval holes 37 having a width equal to the diameter of the threaded portion of the hexagon socket bolt 39. A circular hole 38b having a diameter substantially equal to the diameter of the screw portion of the hexagon socket head bolt 39 is formed in the pressing plate 38.
A screw hole 35a is formed in the inclined surface 35 of the through grooves 28 to 30 perpendicularly to the inclined surface 35, and a hexagon socket bolt 39 is screwed into the screw hole 35a.

When the projection amount of the cutting edges 41 to 43 of the planer blade is adjusted, the hexagon socket bolt 39 is loosened so that the planer blades 31 to 33 can slide along the inclined surface 35. Since the oval holes 37 are formed in the planer blades 31 to 33, it is only necessary to loosen the hexagon socket head bolt 39.
1 to 33 can be slid. In this state, a separately prepared adjustment jig 50 is brought into contact with the cutting surface 10a so as to close the through grooves 28 to 30. This adjustment jig 50
Is a rectangular parallelepiped slightly longer than the length of the through grooves 28 to 30, and the upper surface thereof is a precise flat surface. An adjustment groove 50a excavated by precision processing is formed on the upper surface of the adjustment jig 50, and the blade edges 41 to 41 are formed depending on the depth of the adjustment groove 50a.
The amount of protrusion of 43 is determined.

Before the adjusting jig 50 is brought into contact with the cutting surface 10a, the planer blades 31 to 33 are slid upward to move the blade tip 41.
Withdraw ~ 43. Then, the adjusting jig 50 is brought into contact with the cutting surface 10a, and the planer blades 31 to 33 are lowered until the tips of the cutting edges 41 to 43 come into contact with the bottom of the adjusting groove 50a. Next, with the cutting edges 41 to 43 in contact with the bottom of the adjustment groove 50a, tighten the hexagon socket bolt 39 to remove the planer blade 31.
Secure ~ 33 so that it does not slide. Then, if the adjusting jig 50 is removed, the protrusion amount of the blade edges 41 to 43 is adjusted to the adjusting groove 50a.
Is adjusted to the depth of. As described above, in this embodiment, the amount of protrusion of the cutting edge can be adjusted very easily. Further, the planer blade can be easily replaced by simply removing the hexagon socket bolt 39, and the amount of protrusion of the blade tip after replacement can be easily adjusted.

A plurality of adjusting jigs 50 may be prepared so that the adjusting grooves 50a of each adjusting jig 50 have different depths. Alternatively, one adjusting jig 50 and a plurality of shims having different thicknesses are prepared, and the shims are laid on the bottom of the adjusting groove 50a to adjust the adjusting groove 50a.
You may be able to change the depth of. The shim is a thin piece made of a material such as stainless steel whose thickness does not significantly change due to temperature changes.

4. Release of bite of planer blade When cutting bonito flakes 51 as described above, bonito flakes 51
The cutting edges 41 to 43 of the planer blade may bite into and the rotation of the rotary disk 10 may stop (lock). In the present embodiment, when such a lock due to the bite occurs, the bite can be easily released. First, the switch 19 is turned off to stop the electric motor 2. In this embodiment, an engagement member that engages with the engaged portion 22a at the front end of the output shaft 22 is prepared in advance. This engaging member is a hexagonal wrench that fits into the engaged portion 22a having a hexagonal nut shape. Then, this engaging member is inserted from the through hole 5a of the lid 5, fitted into the engaged portion 22a, and the rotary disk 10 is slightly rotated in the direction opposite to that at the time of cutting. As a result, the cutting edges 41 to 43 of the planer blade are easily released, so that cutting is resumed immediately if the engaging member is removed from the engaged portion 22a and the switch 19 is turned on. In this way, even if the cutting edges 41 to 43 bite and the rotation of the rotary disc 10 is locked, it is not necessary to remove the lid 5 or the rotary disc 10, and the bite and the lock are easily released. be able to. Further, since the electric motor 2 and the food holding portion 12 are provided on the cutting surface 10a side of the rotating disk 10 and the engaged portion 22a is provided on the opposite side of the cutting surface 10a, the above bite When there is no release operation, there is no obstacle in the surroundings, and it is possible to easily perform the bite and lock release operation even with a small engagement member.

5. Modifications Note that the present invention is not limited to the above-described embodiment, and can be variously modified without departing from the spirit of the present invention. For example, FIG.
