Abstract

PURPOSE:To make cutting resistance extremely small by winding one or plural endless band blade with cutting edges formed at its end edge onto plural wheels in such a way that the endless band blade is crossed in a fruit-vegetable feed passage as well as the cutting edges are turned in the same direction. CONSTITUTION:When a start button is pressed, a driving motor 13 is rotated, and an endless band blade 16 travels by the rotation of driving side wheels rigidly fixed at the output shaft of the driving motor 13. When a water melon for instance is put into the insertion port 7 of a table 6, the water melon, while being guided by a guide 8, falls by its own weight within a fruit-vegetable feed passage 9 and hits the cutting edges of the endless band blade 16 in the state of the approximate center of the water melon falling on top of the intersection of the endless band blade 16. This endless band blade 16 is extremely sharp as the cutting edges are formed of a lump 18 of abrasive grain such as diamond, and that in running action. The water melon can be thereby cut into four just by its own weight.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a fruit vegetable dividing and cutting device used when cutting fruit vegetables such as fruits and vegetables into a plurality of pieces at once.

[Conventional technology]

At supermarkets and the like, watermelons, pumpkins, etc. are not only sold individually, but are often cut into pieces and sold for the convenience of small families and single people.

Conventionally, this divisional cutting is performed manually using a knife, and the fruit and vegetables are cut radially around the center of the fruit.

[Problem to be solved by the invention]

However, when cutting large items like watermelon into pieces, it is necessary to make small incisions and cut into pieces, so a cutting tool is required to get a clean cut surface, and it is necessary to cut something as hard as a pumpkin. Considerable force is required to cut.

However, the divisional cutting in which the cut surfaces are created one by one by hand is a labor-intensive and inefficient operation.

For this reason, a dividing cutting device (Japanese Unexamined Patent Application Publication No. 60-104698, Japanese Unexamined Patent Publication No. 60-1989) for cutting fruits and vegetables into multiple pieces has been developed.
-Refer to Publication No. 104699) and split cutting instruments (Refer to Publication No. 104699)
2-46597 and Utility Model Application Publication No. 64-52692) have been proposed.

However, in all of the above techniques, a radially formed blade is pressed against the fruit vegetables to cut them, and although it is possible to cut the vegetables into pieces at once, a large cutting resistance is generated in the fruit vegetables being cut, and when the vegetables are soft, it is difficult to press them. Fruits and vegetables that are easily crushed and hard require an extremely large cutting force, so if the sharpness of the knife is to be improved, the strength of the knife becomes a problem, making it difficult to obtain a clean cut surface.

The present invention aims to solve this problem, and is a device for dividing fruits and vegetables, which can cut both large and soft items like watermelons and hard items like pumpkins at once with a clean cut surface. It provides:

[Means to solve the problem]

In order to achieve the above object, the present invention includes a plurality of wheels rotatably disposed around a fruit and vegetable feeding path having a fruit and vegetable insertion port at one end, and blades formed at the edges. One or more endless belt-shaped blades are wound around the plurality of wheels so that the blades intersect within the fruit and vegetable feeding path and face in the same direction, and a set of wheels around which the endless belt-shaped blades are wound. At least one of the wheels was connected to a rotary drive.

[Effect]

The operation of the fruit and vegetable dividing and cutting device constructed as described above is as follows.

When the wheel connected to the rotation drive unit rotates, the endless band-shaped blade runs.

The fruits and vegetables inserted through the fruit and vegetables insertion port move along the fruit and vegetables feeding path, are cut radially by the endless belt-shaped blades that run in an intersecting manner, and are cut into pieces when they pass through the endless belt-shaped blades. is completed.

〔Example〕

Embodiments of the present invention will be described with reference to the drawings.

Fig. 1 is a partially cutaway front view of a fruit and vegetable dividing cutting device A that cuts fruit and vegetables into four parts, and Fig. 2 is a partially cutaway front view of the same as above.
FIG. 3 shows a side view of the same as above, and the frame 1 has four legs 2, and the two adjacent legs 2 are connected by an upper cross beam 3, an intermediate cross beam 4, and a lower cross beam 5, and the upper cross beam A plate-shaped table 6 is fixedly installed on top of the table 3.

The table 6 is provided with an insertion opening 7 for fruits and vegetables approximately in the center, and four tongue-shaped guides 8 are provided around the periphery of the insertion opening 7.
are vertically disposed at an inclination angle such that their lower ends approach each other, and a fruit and vegetable feeding path 9 is formed inside the guide guide 8.

On the table 6 are a start button 10 and a stop button l1.
An operation panel 12 equipped with a drive motor 13 is installed,
A drive-side wheel 14 and three driven-side wheels 15 fixed to the output shaft of the drive motor 13 are rotatably disposed below the table 6 (see FIG. 4).

The driving wheel 14 and the three driven wheels 15 are arranged at approximately equal intervals around the fruit and vegetable feed path 9, and each wheel 14.15 has an endless wheel with a blade formed on the edge. The belt-shaped blades 16 are wound in a cross-crossing manner, and the endless belt-shaped blades 16 intersect at an angle of approximately 90° approximately at the center of the fruit and vegetable feeding path 9.

Four guides 17 having guide grooves 17a are provided to maintain the intersecting angle of the endless strip blade 16 at about 90 degrees and to orient the blades formed at the edges of the endless strip blade 16 in the same direction.
(See FIGS. 4 and 5), in order for the edge blades of the crossed endless strip blades 16 to face in the same direction, the endless strip blades 16 twisted once as shown in FIG. used.

As shown in FIG. 6, the blade formed at the edge of the endless band-shaped blade l6 is composed of a cluster of abrasive grains 18 such as fine diamonds, and the abrasive grain cluster 18 has a pitch of about 10 MII. 16, the length l of the adhesive surface of the abrasive grain mass 18 is about 2In11, and the thickness b of the abrasive grain mass 18 is 0.6 to 0.8 ribs ( (See Figure 7).

When the endless band-shaped blade l6 travels, a groove for accommodating fine cutting pieces is formed between adjacent clusters of abrasive grains 18, so that the cutting edge becomes extremely sharp.

In order to improve the cutting performance of the endless belt-shaped blade 16, water spray nozzles 20 provided at each of the four outlet ends of the cooling water pipe 19 are arranged near the guide 17, and a cock 21 provided in the cooling water pipe 19 is disposed near the guide 17. When opened, the endless belt-shaped blade 1 moves.
Cooling water is supplied to 6 (see Fig. 4).

The fruit and vegetables feeding path 9 is provided with a chute 22 below the intersection of the endless strip blades 16.

The chute 22 has a slope that becomes lower toward the outlet end projecting outward from the pedestal 1 (see FIG. 3).

The operation of the fruit and vegetable dividing and cutting device A configured as described above will be explained.

When the start button 10 is pressed, the drive motor 13 rotates, and the drive side wheel 14 fixed to the output shaft of the drive motor 13 rotates.
The endless belt-shaped blade 16 travels due to the rotation of the blade.

Next, when the cock 2l is opened, cooling water discharged from the four water sprinkling nozzles 20 is supplied to the endless band-shaped blade 16.

When a fruit vegetable, for example, a watermelon, is put into the insertion slot 7 of the table 6, the watermelon falls under its own weight through the fruit vegetable feeding path 9 while being guided by the guide 8, and the watermelon is almost centered on the endless belt-shaped blade 16. It hits the blade of the endless strip blade 16 so as to overlap the intersection.

The blade of the endless belt-shaped blade 16 is a mass of abrasive grains such as diamond l8
Because it is set up and running, it is extremely sharp, and the watermelon's own weight alone can cut the watermelon into four parts.

Each cut segment slides on the chute 22 and is supplied to a container placed below the end of the chute 22.

In the embodiment described above, the blade of the endless band-shaped blade 16 is made of a lump of abrasive grains 18 such as diamond, but the blade of the endless band-shaped blade 16 may be a knife edge with a sharp cutting edge angle.

Since the endless band-shaped blade l6 is running, the cutting resistance is extremely small even with a knife edge.

When cutting fruits and vegetables into four parts, as shown in FIG. 9, one driving wheel 14 and three driven wheels 1 are used.
5 is arranged, and the endless belt-shaped blade 16 twisted once is wound around the wheels 14 and 15 in a cross-hook manner, and the endless belt-shaped blade 16
The feeding path 9 for fruits and vegetables may be provided at the intersection of the two, but if the endless strip blade 16 is hung on the wheel 14, 15 as shown in FIG. do not have.

When dividing fruits and vegetables into 6 parts, as shown in Figure 11,
An endless belt-shaped blade 16a is crossed over a driving-side wheel l4a having a large thickness dimension and one driven-side wheel 15a, and an endless band-shaped blade 16a is crossed over two driven-side wheels 15b and a driving-side wheel 14a at the intersection thereof. The belt-shaped blades 16b may be overlapped.

Furthermore, as shown in FIG. 12, fruits and vegetables can be divided into six by superimposing an endless belt-like blade 16c that divides them into two at the intersection of the endless belt-like blades l6 that cross over each other to divide the fruits and vegetables into four.

Fig. 13 shows an example of dividing fruits and vegetables into 8 parts, where the intersection of the endless band-shaped blade 16 of the sash-hanging blade that cuts into 4 parts is overlapped with the intersection of the endless band-shaped blade 16 of the sash-hanging blade that cuts the fruit and vegetables into 4 parts. It is something that

As described above, depending on how the endless belt-shaped blades 16 are applied and overlapped, it is possible to divide the blade into any number of even numbers.

〔Effect of the invention〕

Since the present invention is structured as described above, it produces the following effects.

(1) Cutting resistance is extremely low because fruits and vegetables are cut with a running endless band-shaped blade, and both soft and hard fruits and vegetables are cut uniformly and smoothly as the endless band-shaped blade cuts in a straight line. It becomes a smooth plane.

(2) Since the cutting resistance is low, cuts can be made with a force as light as the weight of the fruit and vegetables.

Therefore, there is no need to apply a large external force that would damage the surface of the fruits and vegetables, so that not only the cut edges but also the surfaces of the fruits and vegetables can be kept beautiful, and the fruits and vegetables will not be crushed.

(3) Also, for the same reason, there is no need to provide a complicated mechanism for feeding fruits and vegetables into the fruit and vegetable division cutting device.
The structure of the fruit and vegetables dividing and cutting device and the dividing and cutting operation are simplified.
