DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention is suitable for mass-cutting various types of fish knots such as katsuobushi, mackerel, etc., or processed knots obtained by processing fish meat or animal meat into bonito. The present invention relates to a fish segment cutting device.

[0002]

2. Description of the Related Art When cutting a fish segment by pressing it against a rotary knife, if the fish segment vibrates or wobble, the thickness and shape of the cut segment become uneven. In addition, the yield is deteriorated due to generation of a large amount of powder during cutting, and the obtained cut nodes are curled, and the curled cut nodes are increased, resulting in poor appearance. Further, an excessive force is applied to the rotary knife, and the fish knots are heated by frictional heat, thereby impairing the flavor of the fish knots, and in severe cases, the blade of the rotary knife may even be chipped. These disadvantages are particularly remarkable in the case of spindle-shaped bonito having an uneven shape.

Conventionally, there has been a cutting device which has been filed by the present applicant and published in Japanese Utility Model Publication No. 61-28715, as a cutting device which suppresses such vibration and wobble. As shown in FIG. 27, the receiving surface G is provided at one end in the width direction of the contact surface E.
And a passage is formed, and the rear part of the fish segment A is
And the holding tool D is pushed by the transfer body L to transfer the fish segments A in the direction of the arrow a on the contact surface E of the passage. Is pressed against the rotary blade B while being pressed against the contact surface E from above by a pressing body H provided above and in front of the fish piece A to be cut by the rotary blade B.

The pressing body H is pressed downward by the lifting body J, and the pressing force of the lifting body J moves up and down following the unevenness of the surface of the fish segment A (pressed or pushed back). Set to strength. Moreover, in this fish knives cutting device, as shown in FIG. 28, the pressing surface F of the pressing body H is inclined upward from the left side to the right side in FIG. Are wider on the receiving surface G side. For this reason, the fish segments A pressed by the pressing body H are pushed toward the receiving surface G side (the direction of the arrow b) during the transfer, and the fish segments A are stabilized, are thin to about 4/1000 mm, and have a uniform thickness. Is cut into

Further, since the pressing force of the elevating body J is set so that the pressing body H is pressed or pushed back following the unevenness of the fish segment A, the upper portion of the transferred fish segment A is pressed. Body H
Therefore, there is an advantage that the fishery A is smoothly transferred without being cut off more than necessary and the thrust applied to the fishfish A succumbs to the pressing force and the transfer of the fishfish A is not stopped, and the cutting is stabilized. .

[0006] However, although the fish segments A are pushed toward the receiving surface G by the pressing body H, they are stabilized for the time being, but the force of pushing the fish segments A to the receiving surface 2 by using the pressing body H alone is weak. . Conventionally, as shown in FIG. 29, a side pressing body K to which a pressing force is applied in the direction of arrow x in FIG. 29 is provided on the side opposite to the receiving surface G of the passage as shown in FIG. When a fish segment A transferred on E hits the fish segment A, the fish segment A is pressed against the receiving surface G.

[0007]

However, in the conventional fish knives cutting device, the balance between the pressing force of the pressing body H on the contact surface E and the pressing force of the side pressing body K on the receiving surface G is not sufficient. If not, the transfer of the fish segment A may be stopped depending on the material of the fish segment A. For this reason, it is necessary to adjust the pressing force of both the pressing members H and K, but there is a problem that the adjustment work is troublesome and troublesome, and the workability is poor. Further, since the side pressing body K must be provided, the structure is complicated, and there is a problem that the cost is increased accordingly.

An object of the present invention is to efficiently and surely press fish segments against the abutting surface and the receiving surface of the passage, thereby suppressing vibration and wobbling of the fish segments during cutting, and having a simple structure. It is an object of the present invention to provide a simple fish knot cutting device.

[0009]

[Means for Solving the Problems]

As shown in FIG. 26, the pressing body 3 is a rotating roller that rotates with the transfer of the fish segments A, and the rotating roller presses the fish segments A following the unevenness of the surface of the fish segments A. Alternatively, the fish segments A can be pressed by the pressure of the strength pushed back by the fish segments A.

[0011]

[Action]

In the fish knives cutting device of the present invention, the pressing body 3 is a rotating roller, which presses or pushes back the fish knives A by following the unevenness of the surface of the fish knives A and presses the fish knives A back. Since it is pressable, the fish knots A are pressed with a strength suitable for the unevenness of the surface of the fish knots A, so that it is difficult for the fish knots A to escape during cutting, and it is impossible for the fish knots A to No power is added.

Reference numeral 76 in FIG. 23 denotes an arm to which the pressing body 3 of the roller is attached. This arm 67 is pushed in the direction of arrow a in FIG.
The fish knives A are pressed by a pressure of a pressing or pushing back force following the unevenness of the surface. Due to this, the surface of the fish segment A becomes convex,
When a return force equal to or greater than the pressing force of the cylinder is applied to the cylinder 7, the cylinder 7 is pushed back in the direction of arrow b in FIG.

FIGS. 1 and 2 denote a pressing member which pushes the fish fins A transferred on the contact surface 1 to the contact surface 1 and / or the receiving surface 2 or both or both. It is for pressing between. The pressing body 3 projects downward from the arm 11 and is disposed substantially vertically above the contact surface 1, and the lower end 4 of the pressing body 3 is fish as shown in FIGS. The knots A are bent obliquely toward the transfer direction.
Thus, as the fish segments A conveyed approach the rotary knife B, they pass under the tip 4.

The pressing body 3 may have a shape other than the above. The distal end portion 4 of the pressing body 3 in FIG. 5 is bent so that the receiving surface 2 side opens obliquely upward and outward, so that the fish segments A to be transferred are pressed against the receiving surface 2 side as approaching the rotary blade B. It is.

The pressing body 3 shown in FIG. 6 is provided substantially horizontally above the contact surface 1 in the direction of transport of the fish segments A, and the tip 4 of the pressing body 3 is obliquely downwardly directed toward the contact surface 1.

Reference numerals 3 in FIGS. 25 and 26 denote a pressing member for pressing the fish segments A. The pressing member 3 is provided with a roller. The pressing body 3 is rotatably attached to a lower end of a rotating arm 76, and the rotating arm 76 is attached to a rotating shaft 77 as shown in FIGS. The lower end of the drive arm 78 is attached to a telescopic arm 80 of a drive body 79 such as an air cylinder shown in FIG.

When the drive arm 78 is pushed by the telescopic arm 80 of the drive body 79, the rotation shaft 77 is rotated, whereby the rotation arm 76 is rotated and the pressing body 3 of the roller is moved as shown in FIG.
6 is pressed in the direction of the arrow a to press the fish knots A in FIG. 25 against the gap 81 between the contact surface 1 and the receiving surface 2 of the passage 50. At this time, the pressing body 3 of the roller is adapted to press the fish knives A with the pressure of the strength to be pressed or pushed back following the unevenness of the surface. Due to this, the surface of the fish segment A is convex, so that when a return force greater than the pressing force of the cylinder is applied to the arm 67, the arm 67 is pushed back in the direction of the arrow b in FIG.

The guide 6 shown in FIG. 11 is formed by forming a plurality of grooves inclined downward from the opposite side of the receiving surface 2 toward the receiving surface 2 at uniform intervals in parallel. As shown in FIG. 4B, the arrangement of the guides 6 may be such that the guides 6 are formed radially around the lower side of the receiving surface 2. In this manner, of the fish segments A guided by the guide 6, the opposite side of the receiving surface 2 is pushed more strongly toward the receiving surface 2. The guide 6 may be not a groove but a square bar-shaped ridge that is appropriately separated. The number, depth, length, shape, etc. of the guides 6 are appropriately selected according to the size, hardness, etc. of the fish segments A.

The pressing body 3 has an arc as shown in FIG.
It is attached to the tip of the system 11. The other end of the arm 11 is sandwiched between two support plates 13 erected on the substrate 12, and a shaft 14 is inserted between the support plate 13 and the arm 11 to rotate the coaxial 14. It is mounted so as to be rotatable up and down as a moving shaft. The substrate 12 is attached to the upper surface of the gap adjuster 28 on the receiving surface 2 by bolts 28c so as to protrude above the contact surface 1 as shown in FIGS. In the center of the arm 11, an escape hole 15 is formed as shown in FIG.

A rivet 19 is driven through the horizontally long hole 15 and the lifting rod 7a is connected to the arm 11. As a result, when the elevating rod 7a is extended, the arm 11 pivots downward and the pressing body 3 is pushed down to the contact surface 1, and when the elevating rod 7a contracts, the arm 11 pivots upward. Then, the pressing body 3 is pulled up.

If the lifting body 7 is set to a pressing force that allows the pressing body 3 to move up and down along the unevenness of the fish knots A, the fish knots A stop even if they are pushed to the receiving surface 2 side. It will not be lost. The arm 11 rotates about the shaft 14 in accordance with the vertical movement of the pressing body 3, and the escape long hole 15 of the arm 11 connects the lifting rod 22a and the arm 17. Since the rivet 19 escapes, the elevating rod 7a is moved smoothly in the vertical direction.

When the driving rod 23a is contracted, the upper clamping claw 22a
Is pivoted upward (in the direction of the arrow v in the figure), and the pinching of the fish fin A is released. In this embodiment, as shown in FIG. 16, the upper pinching claw 22a is provided so as to protrude forward from the lower pinching claw 22b.
The tip of the fish segment A sandwiched between 2b always receives the downward moment M, and the fish segment A is pressed against the contact surface 1.

In FIGS. 1 and 2, reference numeral 27 denotes a transfer body which is connected to a jig stand 21 as shown in FIG. It is possible to reciprocate, and this movement reciprocates the clamp 20 of FIG. 16 along the passage 9.

When the fish segments A clamped by the clamp 20 are transferred by the transfer member 27 and pressed against the rotary blade B, the transfer speed (contact speed with the rotary blade) by the transfer member 27 is rotated. If the cutting speed is higher than the cutting speed of the blade B, the jig table 21
May emerge from Therefore, in the present invention, FIG.
As shown in FIGS. 21 and 24, a jig base holding member 70 is attached above the receiving surface 2, above or beside the abutting member 1, and the jig base 21 of the holding member 20 rises up from the passage 9 or vibrates. To prevent them from doing so.

In the case of FIG. 24, since the fish segments A are transferred on the contact surface 1, the width x of the horizontal portion 57 of the contact surface 1 is set to the value shown in FIG.
23, and the rising angle θ of the contact surface 1 in FIG. 24 is preferably selected in the same manner as the angle θ in FIG. 24 is a jig stand (corresponding to the jig stand 21 in FIG. 16).

In FIG. 24, the contact surface 1 is at the upper right, so in this case, the lower surface 21a of the jig base 21 of the clamp 20
Is adjusted to the shape of the contact surface 1 so that the jig base 21 can smoothly move on the contact surface 1 and can be held between the holding claws 22a and 22b of the holding device 20 as shown in FIG. The fish segment A, which is worn with a downward moment M, is always pressed against the contact surface 1 and the receiving surface 2 at the same time even during transportation.

In FIG. 21, the contact surface 1 is downwardly to the right. In this case, the lower surface 21 a of the jig stand 21 is also shaped to match the shape of the contact surface 1, and the jig stand 21 is brought into contact with the jig stand 21. The surface M can be smoothly moved on the surface 1 and a downward moment M is clamped by the clamping claws 22a and 22b of the clamping device 20.
The fish knots A are always pressed against the contact surface 1 and the receiving surface 2 at the same time during transfer.

FIGS. 1 and 2 show a rotary blade B. As the rotary blade B, for example, the rotary blade shown in FIG.
Something like 7 is used. This rotary blade B has a shaft hole 5
On the circumferential surface of a cylindrical base material 51 having zeros, ten or more rows of ridges 52 are formed, notches 53 are formed at regular intervals in each ridge 52, and intermittent blades 54 are formed between the notches 53. ing.
These intermittent blades 54 are arranged such that the intermittent blades 54 of the adjacent ridges 52 are staggered alternately as shown in FIG. 17C.

Further, each intermittent blade 54 has a cutting edge 55
Are arranged obliquely in the direction of the axis. A groove 56 is formed in the rotation direction front of each ridge 52 along the direction in which the intermittent blades 54 are arranged. The cuts cut by the intermittent blade 54 enter the groove 56. in this case,
If the depth of the groove 56 is sufficiently deeper than the cut portion, the cut portion entering the groove will not be broken and shortened. Conversely, if the groove 56 is shallower than the length of the cut portion, the cut portion cannot sufficiently enter into the groove, and the cut portion is broken on the way to shorten the length of the cut portion. In addition, since the end face 54c of the adjacent interrupted blade 54 on the notch 53 side in the same arrangement is formed at right angles to the axial direction of the base material 51, the cut surface and the fish knot are formed on the end face 54c.
Hard to rub, hard to powder, and hard to cut.

The diameter φ and height H (FIG. 17) of the rotary knife B differ depending on the size and size of the fish segment A, but when the fish segment A is small, the size of the fish segment A is 70φ × 60 mm. In the case of a product, it is desirable that the size is about 90φ × 70 mm. Also,
The smaller the number of the protruding ridges 52 of the rotary blade B, the better the shape of the cut is obtained. However, since the cut amount is reduced, 6 to 8 are desirable.

Reference numeral 28 in FIGS. 1 and 2 designates a gap adjusting member which constitutes a part of the receiving surface 2 and is separated from the rear of the receiving surface 2 so as to be closer to the front than the side of the rotary blade B. Is formed. As shown in FIG. 18, the gap adjusting body 28 has a portion 28a facing the rotary blade B formed on the tapered surface from the contact surface 1 side to the outside. The gap adjuster 28 is on an extension of the receiving surface 2 and is slidable in the directions of arrows zy in FIGS. As shown in FIG. 18, the gap adjusting member 28 is screwed to the side surface of the contact surface 1 by a bolt 60 inserted into a long hole 60a formed therein.

Also, behind the gap adjusting member 28, FIG.
As shown in FIG. 8, a screw rod 61 projecting rotatably forward from the receiving surface 2 is screwed. The screw rod 61 has a retaining flange portion 63 provided at a rear end portion in the longitudinal direction thereof set in a notch portion 64 formed on a front upper surface of the receiving wall 2, and a forked engaging portion 66 of a holding member 65. Is inserted between the nut 67 and the flange 63, and the retainer 65 is fixed to the receiving wall 2 with a bolt 68, so that it is rotatably attached to the receiving wall 2.

Then, the bolt 60 is loosened and the screw rod 61 is released.
When the nut 62 fitted to the nut is rotated to the left, the screw rod 61 is rotated. At this time, the screw rod 61 is attached to the receiving surface 2 so as to rotate but not move in the axial direction. Slide in the direction of arrow z. Conversely, when the nut 62 is rotated clockwise, the screw rod 61 is rotated in the opposite direction to the previous one, and the screw rod 61 is loosened from the gap adjuster 28, so that the arrow y in FIGS. Slide in the direction. Thus, the gap adjuster 2
After the gap k (FIG. 18) between the taper surface 28a of FIG. 8 and the outer periphery of the rotary blade B is adjusted to a desired size, the bolt 60 is tightened to fix the adjusting body 28 to the contact surface 1. Thus, even if the diameter of the rotary blade B becomes smaller due to wear, the gap k
By reducing the diameter of the fish segment A, it becomes difficult for crushed fragments to be generated when cutting the fish segment A, and the fragments and fossils of the fish segment A (remaining after cutting) pass through the gap together with the cut portion and mix into the good cut portion. It becomes difficult to do.

The gap adjusting member 28 may have a shape as shown in FIG. 19A, the portion 28a facing the rotary blade B is curved so as to be depressed in accordance with the outer periphery of the rotary blade B. FIG.
In (b), the opposing portion 28a is curved so as to protrude toward the rotary blade B side. In FIG. 19 (c), a protrusion 28c is protruded from the facing portion 28a, and a portion 28d of the protrusion 28c facing the rotary blade B is curved in accordance with the outer periphery of the blade B. FIG. 19D
In this example, a protrusion 28c protrudes in the same manner as in FIG. C, and a portion 28d of the protrusion 28c facing the rotary blade B is a corner.

Reference numeral 32 in FIG. 1 is a lead switch attached to the lifting body 7 of the pressing body 3. This lead switch 32 is for switching the transfer speed of the transfer body 27 to the cutting speed.
When the fish segment A fast-forwarded by 7 presses against the pressing body 3, the pressing body 3 and the arm 11 are pushed upward from the position of the imaginary line to the position of the solid line in FIG. 1
The piston (not shown) in the lifting / lowering body 7 pushing down 1 is raised. The switch 32 is turned on by the rise of the piston, whereby the transfer speed of the transfer body 27 is switched to a low speed for cutting.

In the present invention, the rotary blade B may be installed laterally with respect to the contact surface 1 as shown in FIG. In this case, the abutment surface 1 also serves as the gap adjuster 28, and the receiving wall 2 serves as the arc-shaped recess at the tip of the abutment surface 1.

Reference numeral 30 in FIGS. 1 and 2 denotes a non-defective product box provided at the front of the rotary blade B. The cut pieces that are cut and scattered fall into the non-defective product charging box 30.

In FIG. 1 and FIG. 2, reference numeral 31 denotes a defective product input box provided at the end of the non-defective product input box 30. In the defective product charging box 31, heavy and low air resistance such as crushed pieces and spice generated during cutting is good (thin) due to centrifugal force.
It flies to the end of the cut and falls and is separated.

In the present invention, the fish knots A are transferred to the rotary blade B side at a constant speed by the transfer body 27 shown in FIGS. 1 and 2, and the knots having a uniform thickness can be obtained by keeping the rotation speed of the blade B constant. Can be

According to the present invention, the fish segment A is pressed against the receiving surface 2 and the contact surface 1 by one pressing body 3 as the fish segment A approaches the rotary blade B. So
Fish segment A is reliably stabilized during cutting. Further, since a side pressing body separate from the pressing body 3 is not required as in the related art, the structure is simplified accordingly, the cost is reduced, and there is no need to adjust the pressing force of the two pressing bodies. It is simple.
