The first to sixth pulleys 7, 9, 11, 1
3, 15, 17 are supported on the frame 19 side of the cutting device 1. These first to sixth pulleys 7, 9, 11,
The wire 3 is wound around 13, 15, and 17 to form the cutting action portion 21.

The fourth pulley 13 is configured as a drive pulley in this embodiment. The fourth pulley 13 is connected to a drive shaft 25 of a motor 23 which is a part of the drive means 5. The first, second, third and sixth
The pulleys 7, 9, 11, 17 are configured as driven pulleys in this embodiment.

The fifth pulley 15 is configured as a tension pulley in this embodiment. The fifth pulley 15 is rotatably supported by, for example, the tip of the support arm 27. The base end side of the support arm 27 is rotatably supported on the frame 19 side. A spring 29 is interposed between the intermediate portion of the support arm 27 and the frame 19 side.

In the state shown in FIG. 1, the spring 29 urges the support arm 27 upward to press the fifth pulley 15 against the wire 3. This fifth pulley 1
The wire 3 is tensioned by the pressing force of the wire 5 against the wire 3.

A part of the sixth pulley 17 is immersed in the ultrasonic cleaner 31. Wire 3
Can pass through the cleaning liquid 33 of the ultrasonic cleaner 31. The ultrasonic cleaner 31 contains the cleaning liquid 33 in a cleaning tank 35. The vibrator 37 is provided on the lower surface of the cleaning tank 35.
Are fixed by adhesion or the like.

The cutting table 21 is provided with a supply table 3
9 are arranged. The supply table 39 is supported on the frame 19 side. On the supply table 39, for example, a raw meat block 41 can be supplied to the cutting action portion 21 as a cutting object such as meat.

The base material of the wire 3 has, for example, a wire diameter of 0.
A 1 mm piano wire is used. Material of wire 3,
The thickness is not particularly limited as long as it is suitable for the cutting action, and for example, a piano wire having a wire diameter of 0.2 mm, a stainless wire having a wire diameter of 0.1 mm, 0.2 mm, etc., a wire diameter of 0.2
Various things such as a 7 mm stainless rope can be applied.

The rough surface formed on the wire 3 is, for example, as shown in FIG. FIG. 3A is an enlarged side view of a part of the wire 3. Figure 3 (b),
(C) and (d) are wires 3 according to modified examples of the wire 3.
It is the side view which expanded some A, 3B, and 3C. Figure 3
(E) is an enlarged side view of a part of the wire 43 shown as a comparative example.

The wire 3 has a wire extending direction, that is, as shown in FIG.
A rough surface 45 that repeats unevenness in the vertical direction of (a) is formed on the cutting surface 47. The rough surface 45 has a structure in which the scratches 49 repeat irregularities in the extending direction. The flaws 49 are formed at predetermined intervals in an oblique direction intersecting with the wire extending direction. Cutting action surface 47 on which rough surface 45 is formed
Occupy approximately half of the circumference of the wire 3.

The rough surface 45 may have a structure in which irregularities are repeated in the extending direction of the wire 3, and FIGS.
Various configurations such as (d) are possible.

In the wire 3A shown in FIG. 3B, the rough surface 45A of the cutting surface 47A is formed by an oblique flaw 49A which is in the opposite direction to the flaw 49 of the wire 3.

In the wire 3B shown in FIG. 3 (c), the rough surface 45B of the cutting surface 47B is formed by a flaw 49B orthogonal to the extending direction.

In the wire 3C shown in FIG. 3 (d), the rough surface 45C of the cutting surface 47C is formed by a stitch-like flaw 49C oblique in the extending direction.

On the other hand, in the wire 43 of the comparative example shown in FIG. 3E, the wire 43 does not extend in the extending direction of the wire 43.
Are formed. The flaw 51 of the wire 43 does not contribute to the cutting of an object to be cut such as meat, as is clear from the experimental results described later.

In FIG. 3, the flaws 49, 49
A, 49B, 49C and 51 are shown schematically.

Next, the rough surface 45 can be formed as shown in FIG. In FIG. 4, the flaw 49 is formed by the rotation of the file 53. The file 53 is rotationally driven by the output shaft 57 of the motor 55. As shown in FIG. 4, the portion of the file 53 is obliquely applied to the wire 3, and the wire 3 is moved to the arrow A.
The diagonal flaw 49 can be formed in the wire 3 by rotating the portion of the file 53 by the output shaft 57 of the motor 55 while traveling in the direction.

Other wires 3A, 3B, 3C shown in FIG.
Similarly, it can be similarly easily formed by changing the way of applying the iron 53.

The flaw 51 of the comparative example can be formed by applying the file 53 along the extending direction (axial direction) of the wire 43. Further, even if it is drawn as it is by a wire drawing machine, a flaw close to the flaw 51 is formed.

The roughness of the iron 53 is, for example, 120
No., 400, 800, 1500, etc. are used. However, the rough surface 45, 45A, 45 depends on the file 53.
As long as B, 45C and the like are formed and a cutting object such as meat can be surely cut, it is possible to use a file having other coarseness.

Next, the cutting operation will be described. In FIGS. 1 and 2, when the motor 23 is started, the fourth pulley 13 rotates via the drive shaft 25. By this rotation, the wire 3 tensioned by the fifth pulley 15 travels in the direction of arrow B, for example, and the cutting action portion 21
Move from top to bottom at. This cutting action portion 21
On the other hand, the raw meat block 41 can be cut, for example, sliced by moving it in the direction of arrow C on the supply table 39 and pressing it against the wire 3. At this time, due to the function of the rough surface 45 of the wire 3, the streaks of the raw meat block 41 can be smoothly cut to obtain a clean slice.

The speed of the wire 3 is, for example, 1.00 m.
Although the speed is set to / sec, the traveling speed is not particularly limited as long as the raw meat block 4 can be sliced smoothly.

When the raw meat block 41 is cut, it is difficult for the wire 3 to be adhered with the shavings or the fat. However, even if the shavings or the fat is slightly adhered to the wire 3, the wire 3 is sonicated at the portion of the sixth pulley 17. It passes through the washer 31 and is washed. This cleaning is performed by the cleaning liquid 33 while using the ultrasonic oscillation of the vibrator 37. By adding a degreasing material, a sterilizing material, etc. to the cleaning liquid 33, degreasing and sterilization can be easily performed.

The wire 3 that has passed through the ultrasonic cleaner 31
As described above, the debris removal, degreasing, sterilization, and the like are performed as described above, and the cutting action section 21 is run again to cut the raw meat block 41. By repeating this, the raw meat block 41 can be sliced smoothly.

FIG. 5 is a table showing the results of experiments conducted by the inventor of the present application. As the wire 3, a piano wire, a stainless wire, and a stainless rope were used. The diameter of the piano wire was selected to be 0.1 mm and 0.2 mm, respectively. As the wire diameter of the stainless wire, 0.1 mm and 0.2 mm were selected, respectively. The diameter of the stainless steel rope is 0.2
7 mm was selected.

As for the roughness of the wire, the piano wire having a wire diameter of 0.1 mm is 120, 400, 800, 1500.
I chose each number. For linear 0.2 mm piano wire, 120 and 800 were selected respectively. No. 800 was selected for stainless wire and stainless rope.

The direction in which the flaws are formed by the file is shown with the case of (a) to (d) in FIG. 3 as the horizontal direction and the case of FIG. 3 (e) as the axis. As shown in FIG. 1, the wire 3
When the meat was cut as a result of running and cutting, it was indicated as ◯, and when the meat was not cut, it was indicated as x.

As is clear from the chart of FIG.
The raw meat block 41 could not be sliced when the flaw 51 in (d) was in the axial direction (the extending direction). The reason why the raw meat block 41 could not be sliced is because the muscle of the raw meat block 41 was not cut. When the flaws 49, 49A, 49B, and 49C in FIGS. 3A to 3D were in the lateral direction, the raw meat block 41 could be sliced smoothly.

Moreover, the blade of a general kitchen knife has a diameter of 10 μm.
It is said that it has a radius of m, but even a stainless steel rope with a wire diameter of 0.27 mm, which has a radius 27 times that of r, has rough surfaces 45, 45A, 45B, 45.
When C was included, the raw meat block 41 could be sliced smoothly.

In the cutting experiment, sashimi was sliced using fish meat as a cutting target. As a result, No. 800 was the most suitable as the roughness of the iron 53.

From these, as in the above-described embodiment, the flaw 4 that intersects in the wire extending direction of the wires 3, 3A, 3B, 3C.
Cutting action surface 4 by 9, 49A, 49B, 49C, etc.
When the rough surface 45 is formed on 7, the raw meat block 41 and the like can be sliced extremely smoothly.

When the driving of the cutting device 1 is stopped, the cutting action surfaces 47 of the wires 3, 3A, 3B, 3C,
Even if the operator's hand touches 47A, 47B, 47C, the operator's hand is not cut off, and the safety of the work can be greatly improved.

Since the wires 3, 3A, 3B, 3C do not form a pointed tooth portion as in the conventional case,
The tooth part is not chipped and it does not slip into the raw meat block 41,
The safety of food can be improved.

If the wire has the pointed tooth portion as in the prior art, the tooth portion easily interferes with the pulley and the tooth portion is deformed, so that the cutting function is easily impaired. In addition, cracks are likely to be formed in the roots of the teeth when the vehicle is driven, which causes problems in durability. On the other hand, the wires 3, 3A, 3
Since B and 3C do not form pointed tooth portions as in the conventional case, the tooth portion is not deformed and cracks are unlikely to occur, and the cutting device and the wire rod for the cutting device have high durability. You can

In the conventional structure in which the wire is provided with teeth, flesh and fat are apt to adhere to the teeth, and the whole wire is fleshed.
Although fat tends to adhere, if the wire 3, 3A, 3B, 3C of the above-mentioned embodiment has only the rough surface 45, it is difficult for the carcass and fat to adhere, and in this respect also. Slicing the raw meat block 41 can be performed extremely smoothly.

Even when manufacturing the wire, it is difficult to form the tooth with the conventional structure for forming the tooth.
3A, 3B and 3C have rough surfaces 45, 45A, 45B and 45
It can be easily manufactured by forming C with the hull 53.

Since it is difficult for meat and fat to adhere to the wires 3, 3A, 3B and 3C, the cleaning with the ultrasonic cleaning device 31 or the like can be performed very easily.

The present invention is not limited to the above embodiment. For example, the wires 3, 3A, 3B, 3
Although the cutting action surfaces 47, 47A, 47B, 47C of C are formed on one side of the peripheral surface, they may be formed on the entire peripheral surface. In this case, the cutting action surfaces 47, 4
7A, 47B, 47C has no directivity in the circumferential direction of the wires 3, 3A, 3B, 3C, and the first to sixth pulleys 7,
It can be easily laid between 9, 11, 13, 15, 17 without considering the directionality.

File 53 of the wires 3, 3A, 3B, 3C
The flaws 49, 49A, 49B, and 49C can be formed in various forms as long as the rough surfaces 45, 45A, 45B, and 45C have unevenness in the extending direction.

The rough surfaces 45, 45A, 45B, 45C
Is formed continuously in the wire extending direction of the wires 3, 3A, 3B, 3C, but as long as the raw meat block 41 and the like can be smoothly cut, the rough surface 45 is formed at regular intervals or in the wire extending direction. It is also possible to form at random intervals.

In the above-described embodiment, the rough surface 45 is covered with the metal 53.
Are formed by the wires 3, 3A, 3B, 3C
Rough surface 45, 45A, 45 that repeats unevenness in the direction of the wire
As long as it forms B and 45C, it is not limited to the one by the file 53.

The rough surface 45 can also be formed by a large number of point-like scratches.

The pulley around which the wire 3 is wound can be constructed by using two pulleys and the wire 3 can be wound around the two pulleys. In this case, one pulley can be configured as a tension pulley.
Further, the number of pulleys can be selected in various other ways, and the form in which the wire 3 is wound can also be selected in various ways as long as the cutting action portion 21 can be formed.

The drive pulley is not limited to the fourth pulley 13, and the first, second, third pulleys 7, 9, 11 and the like can be selected as the drive pulley. Further, the motor is set to the first, second, third and fourth pulleys 7, 9,
The V pulley is attached to the output shaft of the motor supported by the frame 19 without being directly connected to any one of 11, 11 and 13, and the first, second, third and fourth pulleys 7, 9, 11, 1
Another V-pulley is coaxially attached to any of No. 3 and a V-belt is wound between the V-pulley and the V-pulley on the motor side, and the wire 3 is driven to travel through the V-belt by driving the motor. It is also possible.

Instead of the ultrasonic cleaning device 31, another cleaning device can be used. For example, a washing machine using steam shower, dry shower, hot water, hot water or the like can be appropriately selected and used.

The moving direction of the raw meat block 41 is as shown in FIG.
Not limited to the arrow C, but depending on the direction of the cutting action surface 47 of the wire 3, the wire 3 may be moved in the direction orthogonal to the paper surface of FIG. In such a case, as described above, the rough surfaces 45, 45A, 45B, 45C have the wires 3, 3
If it is formed on the entire peripheral surface of A, 3B, 3C, it is easy to deal with.

An air cylinder or the like can be used as the spring 29 that applies tension to the wire 3.

In the above-described embodiment, the wire 3 is driven to rotate and run, but it is also possible to configure the cutting action portion 21 by reciprocatingly driving the wire 3, elliptical driving, or the like.

The object to be cut can be applied to something other than food.
