Description

  The present invention relates to a scaly cutter for performing a scaly removal of fish, a power-type scaly remover provided with the scaly cutter, and a scaly removing method.

  In fish dishes, if scales remain, the texture and texture will be significantly impaired, so it is fundamental to carefully remove scales as a preparation. The scale removal is generally performed by using a kitchen knife or various scale removal tools and moving the scale removal tool while pressing the fish head from the tail toward the head. Such a manual scaly remover has poor processing efficiency, and places a heavy burden on the hands and arms, and thus causes great fatigue on the operator.

  In the scaly removal process, a so-called power-type scaly remover that rotates a scaly cutter by electric or pneumatic driving or the like is also used in order to reduce the burden of work when processing in large quantities. For example, the power-type scale remover has a built-in drive source such as a motor in a grip portion, and a scale cutter blade is detachably provided on an output shaft of the drive source. The power-type scale remover has a larger processing capacity than a kitchen knife or a manual scale remover, and can greatly reduce the burden on the operator.

  As power scales, there are provided scales having blades of various shapes. For example, Patent Document 1 and Patent Document 2 describe a scaly cutter with a large number of protrusions integrally formed on the outer periphery of a cylindrical or cylindrical blade body. For example, Patent Document 3 and Patent Document 4 describe a scaly cutter with a large number of axially formed blades integrally formed on the outer peripheral portion of a cylindrical blade body or the like. For example, Patent Document 5 and Patent Document 6 describe a scaly cutter with a plurality of axially formed blades that are integrally formed on the outer peripheral portion of a cutter body, such as a columnar shape, and is composed of concavities and convexities.

  By the way, for example, small scale fish such as small fish, amberjack, yellowtail, etc. The amount of leftovers increases and the processing time increases. Further, for example, a large-scale and hard scale such as sharks and the like, and a large-scale fish scale removes a burden on the operator's hand and arm even when a power-type scale remover is used.

  FIG. 6 is an explanatory view of the scale removing process for peeling the scale 61 from the fish body 60 using the conventional scale removing blade 50 attached to and detached from the power type scale remover. The scaly cutter 50 is formed by arranging a large number (four in the figure) of axial blades 52 adjacent to each other in the circumferential direction on the outer periphery of a blade body 51 formed in a cylindrical shape or the like by a metal material. The scalpel cutting blade 50 is formed by integrally forming a blade portion 52 with a substantially trapezoidal cross section from the blade body 51 and forming a blade edge 54 at the tip portion with the side surface 53 on the moving direction B side as a substantially vertical surface. That is, the scale removing blade 50 is formed such that the side surface 53 of the blade portion 52 is a flat surface that forms substantially the same surface with respect to the rotation axis 55.

  The scaly cutter 50 performs scaly removal by pressing the cutting edge 54 against the fish body 60 while being rotated in the direction indicated by arrow A in FIG. Due to the shape of the blade portion 52 described above, the scaly cutter 50 has a side surface 53 of the blade portion 52 that collides with the scaly 61 at an angle close to a right angle, and bites the root portion of the scaly 61 into the fish body 60. I will let you.

  In the scaly cutter 50, a push-back force from the fish 60 is applied to the scaly 61, and the load on the blade 52 gradually increases as the root portion bites into the fish 60. For this reason, in the scale removing blade 50, the blade portion 52 must be strongly pressed against the fish body 60 and moved with a large force, and the weight of the scale portion is heavy for the operator. It was.

  Further, in the scale removing blade 50, for example, when used for small fish such as small fish, amberjack, yellowtail, etc., the blade portion 52 cannot enter between the fish body 60 and the small scale 61 so that the scale is removed. There was a problem that I couldn't. Furthermore, the scale removing blade 50 has a problem that when the scale 52 is used for a fish having a small scale and a large amount of slime such as a flounder, the scale 52 cannot be removed because the blade 52 slides on the scale 61. It was.

  Note that when the scaly cutter 50 is formed in a columnar shape or a cylindrical shape as a whole, it is difficult for the cutting edge 54 to wrap around a complicated part such as a small fish or a head, or a part such as a fin. As a result, the finishing process was required to remove the remaining scale.

  As described above, the scale removal process uses a power-type scale remover, thereby reducing the process efficiency and the burden on the operator as compared with a method using a manual jig or the like. However, even with a power-type scale remover, further improvements are required for reducing the burden on the operator and increasing the efficiency of the processing due to the structure of the blade 50 described above. Moreover, even if a beginner is a power-type scale remover, the scale 61 such as a small scale fish or a flounder can be processed easily and reliably quickly with a small scale-rich fish such as a scale fish. It is desired. Similarly, it is easy for large fish such as sea bream. It is desired that it can be performed quickly and reliably and is inexpensive.

  In a power-type scale remover, by using a scale remover with a rake angle on the first side of the blade, the blade tip reliably catches the scale as it moves and enters the root from its tip. , Peel off from the fish body by peeling off and jumping while raising the scales by rotating. In a power-type scale remover, the blade tip is prevented from slipping on the scale, and as it moves, the scale is peeled off while being guided along the side surface from the blade tip to the blade bottom. Ensure that the load is reduced. In the power-type scale remover, even if the scale is small or the scale is small and the fish has a lot of slime, the scissors can be removed by the blade tip reliably entering between the fish body and the scale. Therefore, in the power-type scale remover, it is possible to efficiently carry out the high-end scale removal process while reducing the burden on the operator.

The invention according to claim 6 that achieves the above-described object is the scale cutter (1, 30, 40) according to any one of claims 1 to 4 or the power type according to claim 5. It is a scale removing method using a scale remover (15) .

  In the scaly removal method, by using a scaly cutter with a rake angle on the first side surface of the blade part, the blade tip surely catches the scalpel as the scaly cutter is moved and moves from its tip to the root. It enters and peels off from the fish body by peeling off and jumping while raising the scale by rotating. In the scaly removal method, the blade tip is prevented from slipping over the scaly, and as it moves, the scale is peeled off while guiding the scalpel along the side surface from the blade tip to the blade bottom, so the load of the moving force is reduced. To be reduced. In the scaly removal method, even if the fish is small or the fish is small and has a lot of slime, the scalpel can be removed by the blade tip reliably entering between the fish body and the scale. Therefore, in the scale removing method, it is possible to efficiently carry out the scale finishing process with high finish while reducing the burden on the operator.

According to the first aspect of the present invention, in particular, when it is formed at 10 ° which is the center of the above range, a processing efficiency of approximately 50% or more can be achieved as compared with a conventional blade.
In addition, when the rake angle α is formed to be 3 ° or less outside the above specified lower limit, that is, the load from the fish body side is increased by the first side surface striking in an orthogonal state against the scale. There is no harm.
Conversely, there is no harm when the rake angle α is set to 20 ° or more, which is outside the above specified upper limit, that is, there is no harm that damages the skin and meat when the blade edge hits the fish body sharply.
Further, since the number of blade portions is set to 4, the blade portion is formed such that the blade height H gradually decreases from the proximal end toward the distal end side, and the rake angle α is optimal. Combination effect is obtained.
In addition, by forming the blade height H to 8 mm or more and 13 mm or less as defined in the invention according to claim 2, for example, a scale such as a 1.0 kg-1.3 kg gutter supplied to the market It is possible to efficiently remove scales having a size of about 9 mm to 10 mm.
As an example that deviates from the above regulations, the blade height H is too small for the scale size, that is, the tip of the scale hits the blade bottom before the scale is peeled off from the fish body, etc. When a scale is used to process a large fish, a part of the scale that has been peeled off gradually accumulates at the bottom of the blade, and the amount of blade height H accumulates and reaches the blade tip, making it unusable. There is no harm.
On the contrary, there is no harm that the blade height H is too large, that is, the distance from the rotation axis to the blade edge, that is, the distance from the fulcrum to the action point, and the load on the force point, that is, the gripping body is increased.

It is sectional drawing of the scaly cutter shown as 3rd Embodiment. It is explanatory drawing of the scale removal operation | movement by the conventional scale removal tool.

  Hereinafter, a scale removing blade (hereinafter abbreviated as a blade) 1 shown as an embodiment of the present invention and a power-type scale removing machine (hereinafter abbreviated as a scale remover) in which the blade 1 is attached to and detached from a gripping body 16. .) 15 will be described in detail. The blade 1 includes a blade body 2 and a plurality of blade portions 3, and is attached to and detached from a rotation shaft 18 of a rotation drive unit 17 that omits details built in a drip-proof gripping body 16. Configure.

  The scale remover 15 is connected to a control box (not shown) with a cord drawn out from the gripping body 16, and power is supplied to the rotation drive unit 17. In the scale remover 15, the control box is connected to a commercial power supply (AC power supply), performs AC-DC conversion with a predetermined voltage direct current, supplies it to the rotation drive unit 17, and sets the rotation speed of the blade 1 To have a volume. The control box includes, for example, a power on / off switch, a pilot lamp that lights and displays a power connection state, and the like.

  The scale remover 15 efficiently moves the scale 21 without damaging the fish body 20 by moving the blade 1 from the tail side to the head side while lightly pressing the fish body 20 with the blade 1 rotated by the rotation drive unit 17. Strip off. The rotation drive unit 17 of the scale remover 15 is configured by, for example, an electric motor capable of rotation control. Although not shown, the scale remover 15 may be provided with an on / off switch on the gripping body 16, and the rotary drive unit 17 may be started and stopped by operating this switch. The scale remover 15 is not limited to an electric motor as the rotation drive unit 17, and may be an air motor that is connected to an air pressure supply unit and is driven to rotate. Although the scale remover 15 is provided exclusively for business use, it may be a small, low-torque household scale remover in which the grip body 16 houses a motor that uses a battery as a power source.

  The blade 1 is made of, for example, a rod-like metal material such as a stainless material having rust prevention property, and a plurality of blade portions 3 are formed on the blade body 2 by, for example, a cutting method for the metal material. A blade edge forming process is performed on the tip to form the blade edge 4. Note that the blade 1 may be formed by integrally forming the blade body 2 and the plurality of blade portions 3 by a casting method such as the lost wax method and performing a blade edge forming process on the tip of the blade portion 3. . Of course, the blade 1 may form the cutting edge 4 by quenching the blade portion 3.

  As shown in FIGS. 1 and 2, the blade body 2 is formed of a round bar-like body, and one axial region is configured as a proximal end region portion 5 that is attached to and detached from the rotary shaft 18 of the scale remover 15. The blade body 2 integrally forms a plurality of blade portions 3 on the outer peripheral portion with the other axial region as a blade portion forming region portion 6. In the blade body 2, a shaft fitting hole 7 having substantially the same diameter and the same length as the rotation shaft 18 is formed inside the proximal end region portion 5. The shaft fitting hole 7 is an axial shaft hole that opens in the distal end surface of the base region 5, and two screw holes are provided at different positions in the circumferential direction.

  The cutter 1 is attached to the rotary shaft 18 by the set bolt 8 screwed into the screw hole and rotates integrally with the rotary shaft 18 fitted in the shaft fitting hole 7 from the opening at the tip. The blade 1 is removed from the gripping body 16 of the scale remover 15 by removing the set bolt 8.

  Although the cutter 1 is configured to attach and detach the scale 15 with the screwing structure including the screw hole and the set bolt 8 as described above, it is needless to say that the cutting tool 1 is not limited to such a screwing structure. The cutting tool 1 may be configured to have a detachable structure with a key structure in which, for example, a keyway and a key are fitted and integrated instead of the above-described screwing structure. Furthermore, the blade 1 may be configured to have a detachable structure with a reverse screw structure that is threaded in the direction opposite to the rotation direction.

As shown in FIGS. 1 and 2, the blade portion 3 is composed of four axially-shaped rib-shaped convex portions 3 </ b> A to 3 </ b> D that are formed at equal intervals on the outer peripheral portion of the blade portion forming region portion 6. . The blade portion 3 has a ridge line portion formed by a first side surface 9 on the front side in the rotational direction and a second side surface 10 on the rear side in the rotational direction rising from the outer peripheral portion of the blade portion forming region portion 6. As shown in FIG. 1, the blade portion 3 gradually decreases the blade height H from the proximal region portion 5 side toward the tip portion as a whole, and the tip distance D between the blades at the center symmetrical position as shown in FIG. It forms in the blade part formation area | region part 6 which becomes a small diameter gradually toward the side.
In addition, the number of the blade parts 3 formed in the outer peripheral part of the blade part formation area | region part 6 of the cutter main body 2 at equal intervals is not limited to four pieces.

  The blade portion 3 is formed in an arc shape as shown in FIG. The blade portion 3 can be scaled by guiding the tip portion 11 to a complicated portion such as a small fish or a head or a portion around a fin by forming the tip portion 11 in a circular shape with a small blade height, The versatility is improved along with the efficiency of the scale removal process. Needless to say, the blade portion 3 may be formed to have substantially the same diameter throughout, but when used for a small fish or the like, the efficiency is lowered.

  As shown in FIG. 2, the blade portion 3 is set such that the blade opening angle β formed by the adjacent first side surface 9B and second side surface 10A is approximately 90 ° or slightly larger than 90 °. As shown in the figure, the blade portion 3 is provided with a so-called rake angle α so that the first side surface 9 recedes in the counter-rotating direction with respect to the surface connecting the rotary shaft core 12 and the blade edge 4 as an inclined side surface. It is formed. The blade portion 3 is formed in a convex shape that gradually recedes from the blade edge 4 toward the base end portion by adding a rake angle α to the first side surface 9. The blade portion 3 is formed with a rake angle α in the range of 3 ° to 20 °. The blade portion 3 is preferably formed with a rake angle α in the range of 5 ° to 15 °.

  As the blade portion 3 is moved during the scale removal operation described later, the blade edge 4 enters inward from the tip portion of the scale 21 and peels off from the fish body 20. The blade portion 3 is prevented from slipping freely on the scale 21 by being given a rake angle α, and as the blade 3 moves, the blade edge 4 reliably catches the scale 21 from the tip portion to the root. Enter towards you. The blade portion 3 is peeled off from the fish body 20 by peeling off and jumping while raising the scale 21 by a rotating operation.

  In addition, the blade portion 3 enables the scaly removal of the fish with a small scale 21 and a fish with a small scale 21 and a large amount of slime by the blade tip 4 entering between the fish body 20 and the scale 21 with certainty. Therefore, the blade part 3 implement | achieves the cutter 1 which implements a highly finished scale removal process efficiently, reducing an operator's burden.

  When the rake angle α is 3 ° or less, the blade part 3 has the first side surface 9 abuts against the scale 21 in an orthogonal state like the above-described conventional blade 50 and increases the load from the fish body 20 side. End up. When the rake angle α is 20 ° or more, the blade 3 sharply hits the fish body 20 and damages skin and meat. When the blade portion 3 was formed with a rake angle α of 10 °, a processing efficiency of approximately 50% or more was achieved compared with the conventional blade 50 without causing damage to the skin and meat.

  As described above, the blade portion 3 peels off the scale 21 from the fish body 20 and jumps away to remove the scale. However, a part of the scale 21 moves from the blade edge 4 to the blade bottom and is peeled off. The blade portion 3 becomes unusable when a part of the scale 21 that has been peeled off gradually accumulates at the blade bottom and the amount of the blade height H accumulates and reaches the blade edge 4. On the other hand, when the blade height 3 is increased, the distance from the rotary shaft core 12 to the blade edge 4, that is, the distance from the fulcrum to the point of action increases, and the load on the gripping body 16 that is the power point increases. For this reason, the blade height 3 of the blade portion 3 is appropriately set according to the amount of work and the fish to be processed.

  For example, when the scalpel 21 processes a large fish, such as a salmon, the blade 3 may hit the bottom of the blade before the scaly 21 is peeled off from the fish body 20 if the blade height H is small. is there. For this reason, since the load becomes large because the scale portion 21 exists in a wedge shape between the blade edge 4 and the blade bottom, the blade portion 3 appropriately sets the blade height H according to the target fish. It is preferable.

  The blade portion 3 is formed by setting the blade height H on the proximal end region portion 5 side to at least 8 mm or more, preferably 9 mm to 12 mm, and a maximum of 13 mm. The blade portion 3 has, for example, a scale of 1.0Kg to 1.3Kg supplied to the market and a scale of about 9 mm to 10 mm. Can be performed efficiently.

  The scale removing operation using the blade 1 configured as described above will be described with reference to FIG. The blade 1 is integrated with the rotary shaft 18 by fitting the rotary shaft 18 on the scale removing machine 15 side into the shaft fitting hole 7 from the tip opening of the blade body 2 and tightening with the set bolt 8. The blade 1 rotates integrally in the direction of arrow A when a switch operation is performed on the scale remover 15 side and the rotation shaft 18 is rotated by the rotation drive unit 17.

  As with the conventional scaly blade 50, the blade 1 is also rotated by pressing the blade 3 against the fish body 20 with its head held down and moving it from the caudal side toward the head side as indicated by the arrow B. I do. In the blade 1, the blade 21 is peeled off from the fish body 20 by rotating the blade tip 4 inward from the tip portion of the blade 21 as the blade portion 3 is moved. In the blade 1, since the rake angle α is added to the first side surface 9, the blade edge 4 smoothly enters inward without sliding from the scale 21. In the blade 1, the cutting edge 4 is given a rake angle α on the first side face 9, so that the scalpel 21 is surely caught as it moves and enters the root from its tip portion. In the blade 1, the blade edge 4 is peeled off while raising the scaly 21 by the rotation operation, and then flung away from the fish body 20.

  In the blade 1, the load due to the contact between the blade portion 3 and the scale 21 is greatly reduced. In the blade 1, the scale 21 is peeled off with high accuracy and efficiency while reducing the operator's operating force without causing damage to the fish skin or meat. Moreover, in the blade 1, the reaction force from the scale 21 is divided in the height direction by guiding the scale 21 along the first side surface 9 with the rake angle α, and the load of the moving force Is reduced to reduce the burden on the operator so that an efficient scaly removal operation is performed.

  In the blade 1, even for a fish with a small scale 21 or a fish with a small scale 21 and a large amount of slime, the cutting edge 4 surely enters between the fish body 20 and the scale 21, so that the scale can be removed. Therefore, in the blade 1, it is possible to efficiently carry out the highly finished scale removing process while reducing the burden on the operator.

  In the above-described blade 1, the blade portion 3 is configured by the first side surface 9 and the second side surface 10 to form a straight blade-shaped blade portion 3. In the blade 1, for example, when the scale 21 processes a large fish such as a spear of 2.0 kg or more, the load of the blade portion 3 that directly hits the scale 21 increases. The blade 30 shown in FIG. 4 as the second embodiment of the present invention is characterized by the configuration of the blade 31 that reduces the burden on the operator when processing the fish 20 having the large scale 21. . Since the blade 30 has the same configuration as the blade 1 except for the blade portion 31, the corresponding portions are denoted by the same reference numerals and the description thereof is omitted.

  The blade 30 is characterized in that a plurality of concave portions 33 are formed in a blade edge 32 of a blade portion 31. The blade 30 is formed in a sawtooth shape by forming concave portions 33 at predetermined intervals in the axial direction along the blade edge 32.

  In the blade 30, since the plurality of recesses 33 are formed in the blade edge 32, the scale 21 that directly hits the blade edge 32 through the recesses 33 is reduced. In the blade 30, peeling off is left at the corresponding portion of the recess 33, but the load due to the reaction force from the scale 21 is reduced by partially forming the blade tip 32 that directly contacts the fish body 20.

  The blade 40 shown in FIG. 5 as the third embodiment of the present invention is characterized by the structure of the blade portion 41 that efficiently removes the scale 21 peeled off from a large fish and suppresses scattering. Since the blade 40 has the same configuration as that of the blade 1 except for the blade portion 41, the corresponding parts are denoted by the same reference numerals and the description thereof is omitted.

  As for the blade 40, the ridge line portion constituted by the first side surface 43 on the front side in the rotational direction and the second side surface 10 on the rear side in the rotational direction rises from the outer peripheral portion of the blade portion forming region 6. It is said. The cutting tool 40 is characterized in that the first side surface 43 is provided with a rake angle α in the same manner as the first side surface 9 described above, but is constituted by a concave curved surface.

  In general, the scale 21 is still flexible as soon as it is peeled off from the fish body 20. In the blade 40, the cutting edge 42 smoothly enters between the fish body 20 and the scale 21 as described above by attaching a rake angle α to the first side surface 43 of the blade portion 41, and peels off the scale 21. In the blade 40, the scale 21 is guided from the blade edge 42 to the blade bottom along the first side surface 43, and at that time, moves while rolling along the concave curved surface.

  In the blade 40, the abutment of the scale 21 against the blade portion 41 is thereby reduced, and the load is further reduced. In the blade 40, the scale 21 is peeled off as if the scale 21 is wound as described above, whereby the scale 21 is peeled off smoothly, and the load can be reduced.

  The scale remover 15 is a power-type scale remover that peels off the scale 21 from the fish body 20 when the blades 1, 30, and 40 described above are attached to and detached from the gripping body 16, but is also applied to uses other than the scale removal process. The The scale remover 15 can also be used for applications such as removal of deposits from oyster shells or removal of slime from strawberries. The scale remover 15 is applied not only to marine products but also to agricultural products such as taro peels.
