Description

  The present invention relates to a kitchen knife used when, for example, a raw fish body of fish paste products such as salmon, and more particularly to a kitchen knife provided with a scraping member such as a brush member or a scale member.

  Fish paste products such as salmon are generally made from white fish surimi such as walleye pollock and guillo (Ishimochi). .

  Specifically, the fish body is washed, the scales are removed, the head is dropped, the belly is removed, the internal organs are taken out, washed, opened in two pieces, and the fish meat is collected. Then, it is exposed to water, dehydrated and used for the surimi preparation process. Processing until fish meat is collected is almost done only with a knife.

  However, while the improvement of the working efficiency is desired, the internal organs must be removed from the surimi fish meat. Especially for fish for salmon, the surimi raw material is crushed and gelled by heating after molding, but if blood remains, not only the color of the salmon product will deteriorate, but it will also be characteristic as a product when gelled. The elasticity which becomes a texture will fall and it will become a thing with bad quality.

  The removal of internal organs from the fish body is mainly performed with a kitchen knife, but as shown in the schematic diagram of FIG. 9, the kidney 102, which is mostly a blood coagulation substance, is attached along the spine bone 101. It is difficult to peel the kidney 102 from the fish body 100 without damaging it. Conventionally, after the removal of the internal organs, the remaining kidney 102 has been scraped off with a brush in order to remove it cleanly so that blood does not adhere to the fish meat 100 as shown in FIG.

  However, for this reason, it is necessary to change to a brush in the middle of the process of lowering the fish with a kitchen knife, and then change again to a kitchen knife and then continue the process, especially when a large amount of fish is taken down. It was inefficient. Furthermore, when such a brush is prepared, the work space is reduced. Or while processing the fish with a kitchen knife, it must be placed at a relatively distant position that does not interfere with the work, and the troublesome work of extending the hand, taking the brush, and extending the hand was necessary . In addition, there is a possibility that the brush may fall from the workbench, and in that case, it may be troublesome to pick up and wash.

  On the other hand, a dedicated fish internal organ removal tool as disclosed in Patent Document 1 is also considered, but the internal organs are taken out from the mouth without breaking the belly. Is not necessary.

  In such a fish meat collection process, there is a demand for a method that can cleanly remove internal organs including the kidney while allowing a large amount of fish to be processed more efficiently.

  Therefore, for example, a belt that sandwiches the fish body is sent by a belt rotation mechanism in which a rotary blade for fish laparotomy, a rotary blade for visceral incision, a rotary claw for scraping off the internal organs, a rotary brush for removing internal organs, etc. are lined downward. A method for removing the internal organs of fish that is automatically processed is considered (for example, see Patent Document 2).

  In addition, a kidney removal device is considered in which a body cavity membrane is cut with a cutter against a fish body fixed by a posture control mechanism, and then the kidney is inhaled and removed by an inhalation nozzle (see Patent Document 3).

JP2012-152123A JP-A-4-16143 JP 2004-321031 A

  However, in the method of automatically performing the laparotomy or removal of the internal organs with the above-mentioned device, the large amount of processed fish bodies are not exactly the same size, and the internal organs including the kidneys are always sufficiently clean without losing their bodies. There is no guarantee that it can be removed. In addition, devices equipped with posture control mechanisms and inhalation mechanisms that fix fish bodies are inefficient unless they are large fish bodies, and are intended for fish bodies such as walleye pollock and gusset that serve as raw materials for surimi and other paste products. Not practical in case.

  Therefore, at present, a method for removing the internal organs using a brush or the like by a human manual operation is practical for fish processing for collecting fish meat, which is a high-quality salmon raw material.

  In addition, usually when we fish fish, we take scales on the surface of the fish body, and if you are an expert, you can scrape well and efficiently using a kitchen knife, but if not, scales will scatter, Dedicated scales are sometimes used because the fish body breaks down and the blade blade wear becomes noticeable. In this case, the change to the kitchen knife has hindered work efficiency.

  In view of the above problems, an object of the present invention is to provide a kitchen knife that can perform scraping operations such as removal of a viscera including a kidney from a fish body and scale removal more efficiently and better than before. .

  In order to achieve the above object, a kitchen knife according to the first aspect of the present invention is a kitchen knife for scooping a fish, comprising a knife body having a blade and a handle portion to which the blade is coupled, It further comprises a scraping member attached to the handle bottom of the handle portion.

  A knife according to a second aspect of the present invention is the knife according to the first aspect, wherein the scraping member comprises a brush bristle material and a flocking table in which the brush bristle material is implanted. It is a member.

  A knife according to the invention of claim 3 is the knife according to claim 2, wherein the brush table of the brush member has a central axis in the longitudinal direction at least near the handle portion in the axial direction of the handle portion of the knife body. Is warped in a direction away from the cutting edge at a predetermined inclination angle.

  According to a fourth aspect of the present invention, there is provided a knife according to the first aspect, wherein the scraping member is detachably attached to the handle bottom portion via a locking means. Is.

  According to the kitchen knife of the present invention, since the scraping member is attached to the handle bottom of the kitchen knife body, in the process of lowering the fish body, it is necessary to immediately change the direction of the kitchen knife without releasing the kitchen knife. The scraping operation can be performed, and then the processing process using the next kitchen knife can be continued only by changing the direction of the kitchen knife again. Therefore, it is possible to eliminate the labor of releasing the kitchen knife from the hand and holding it again, and in the process of lowering a large amount of fish, it is possible to collect high-quality fish meat more efficiently than conventional methods. There is an effect of becoming.

It is a fragmentary figure which shows the other example of the brush member in this invention. It is a fragmentary figure which shows another example of the brush member in this invention. It is a fragmentary figure which shows the other structure of the brush member in this invention. It is a fragmentary figure which shows the case where the scraping member in this invention is used as a scale member. It is a schematic diagram which shows the state in which the kidney remains in the middle of the process of lowering the fish for raw fish. It is a schematic diagram which shows the state after removing the kidney in the middle of the process of lowering the fish for raw fish.

  In the present invention, since a scraping member, that is, a brush member or a scale member, is attached to the handle bottom of the kitchen knife body for lowering the fish body, in the process of lowering the fish body with the kitchen knife, The scraping member can be used simply by changing the length, and after the necessary scraping operation is completed, the processing step using the next knife can be continued immediately by simply returning the orientation of the knife body. Therefore, in the process of lowering a large amount of fish, it is possible to eliminate the trouble of releasing the knife and holding the dedicated member for the scraping work, and there is also a space for preparing another tool. It is no longer necessary, and it is possible to collect high-quality fish meat more efficiently than before for a large amount of fish while being manually performed.

  As the scraping member, first, a brush member for removing the remaining kidney after removal of the internal organs can be mentioned. In this case, after removing the internal organs by breaking the belly of the fish with a knife, change the direction of the knife body, apply the brush member to the fish body, scrape and remove the kidney, and then immediately return the knife body to the next direction. It is possible to continue the processing step using the knife.

  Also, if the scale member is attached to the handle bottom of the kitchen knife body as the scraping member, the knife body should be oriented so that the scale member hits the fish surface. By simply setting the knife body so that the blade edge of the body touches the fish body side, it is possible to continue the work with the kitchen knife by subsequently dropping the head of the fish body.

  The action of changing the direction of the knife body with respect to the fish body between the blade side and the scraping member side is based on the use state of the knife with the handle part held and the blade edge of the blade pointed at the fish body in the reverse direction. It can be changed to the use state of the scraping member by holding it again. However, depending on the attachment state of the scraping member to the handle member, it is possible to change the use state by changing the orientation of the knife body simply by returning the wrist. In this case, the handle portion is gripped by hand when the knife is in use, and the handle portion is gripped by hand when the scraping member is used. According to such an operation of simply returning the wrist, the direction of the knife body can be changed in a shorter time than holding the handle portion, and thus the work efficiency can be further improved.

  Specifically, the state of attachment of the scraping member that is effective to change the orientation by simply turning the wrist is that the head part where the scraping member actually contacts the fish body is processed to some extent from the tail end of the handle bottom It is in a state of being attached without having too far away. In this state, if the head part is separated from the little finger side of the fist holding the handle part, the head part is in contact with the hand part area. In addition, the scraping operation can be performed without the carpal region touching the fish body, and the force can be smoothly transmitted to the head portion, so that a better scraping operation can be performed.

  When the scraping member is a brush member, the head portion is a flocking table in which a brush bristle material is embedded. If the handle part of the kitchen knife body is long enough that the operator's little finger side carpal part does not protrude from the tail end of the handle bottom part, the end part of the flocking table can be attached almost directly to the handle bottom part. no problem. However, when it is desired that the head portion of the brush member be arranged at a further distance from the handle bottom portion of the kitchen knife body, the brush member includes a shaft portion extending from the flocking table, and the flocking of the shaft portion It can be set as the structure by which the front-end | tip on the opposite side to a base is attached to the tail end of a handle | steering-out part.

  In order to satisfactorily scrape off the internal organs (kidney) with the brush in the reverse hand state, the center axis of the flocking table in the longitudinal direction at least in the vicinity of the handle bottom is predetermined with respect to the axis direction of the handle portion. It is desirable to have a tilted angle and warp in a direction away from the blade edge. If the inclination angle of the flocking table is within a range of 30 ° to 60 °, the scraping operation with the brush can be performed well even with the reverse hand. When the flocking table is attached to the tail end of the handle bottom part via the shaft part, the central axis of the shaft part is coaxial with the knife body, and the axis of the flocking table is relative to the central axis of the shaft part. What is necessary is just to set it as the structure which warps the flocking table within the range of the said inclination angle in the boundary vicinity with a part.

  Further, the entire brush head may be curved in the longitudinal direction. In this case, in the scraping work in which the ground contact surface of the bristle tip is curved and the shaft part rotates around the wrist, the bristle tip touches the internal organs while moving on a substantially arc, so the scraping force is relatively uniform It can be difficult to break.

  In particular, since the kidney scraping operation needs to be performed carefully and efficiently so as not to flow into the fish body, the angle of the head portion of the brush member can be set to a position where the operator can easily work. It is preferable that adjustment is possible. This is a configuration in which the flocking table can be rotated with respect to the axial direction of the knife body so that the grounding angle and scraping angle of the hair material tip of the head portion with respect to the fish body can be changed even when used in the opposite hand state. That's fine.

  In this case, it is simple to use a configuration in which a flocking table is attached via the shaft portion and to provide a mechanism that enables the flocking table to rotate relative to the shaft portion. That is, a connecting portion is provided between the flocking table and the shaft portion, and the flocking table can be rotated within a predetermined angle range around the central axis of the shaft portion at the connecting portion. It is assumed that a positioning mechanism for releasably fixing the flocking table with respect to the shaft portion at the angular position is provided.

  As the brush bristle material of the brush member attached to the handle bottom of the knife in the present invention, those commonly used in foods etc. can be adopted, for example, various chemicals such as nylon, polypropylene, vinyl chloride, polyester, etc. The thing made from various vegetable fibers, such as a thing made from a fiber, and palm, palm, a karkaya etc. which are used for a scourer, can be employ | adopted. However, it is desirable to have a certain degree of elasticity and waist strength, but also a flexibility that does not damage the kidneys. In particular, among the plant fibers, those which are weak against friction and easily break can be avoided because the slices are likely to adhere to the fish body, and in the treatment of a large amount of fish body, the service life is short. Moreover, the flocking table and the shaft portion are made of plastic, and can be easily manufactured by integrally forming both into a desired shape.

  As for the shape of the head part of the brush member, the hair material is uniformly embedded in the flat or curved flocked surface of the flocking table made of a flat plate member, and the ground contact surface of the bristles is flat or curved. Not only a general brush form, but also various types such as those in which a hair material is implanted substantially radially on an arcuate flocked surface, and a tornado-like torsion brush can be widely employed.

  In addition, the conventional dedicated scale remover has a metal head portion with a large number of protrusions formed integrally with the same metal handle portion, or a metal handle portion with a wooden handle portion. Generally, a head portion made of metal is fixed. Even in such a scale remover, in many cases, the head portion is inclined with respect to the handle portion so as to facilitate the scraping operation.

  Therefore, when the scraping member in the present invention is a scale member, the same metal head portion is used as a shaft portion with a certain length of the shaft portion, and the tail end of the handle bottom portion of the kitchen knife body through the shaft portion. Just attach it to In this case, if the tilting direction of the head portion with respect to the handle portion (shaft portion) is attached so as to warp away from the blade edge of the blade, the scraping operation as a scale can be satisfactorily performed even in the reverse hand state. The metal head portion may be curved along the longitudinal direction. In this case, the ground contact surface of the tip of the protrusion becomes a curved surface, and in the scraping work in which the shaft portion rotates around the wrist, the protrusion tip contacts the fish surface while moving on a substantially arc, so the scraping force is relatively uniform It can be difficult to break.

  Moreover, the attachment of the scraping member such as the brush member or the scale member as described above to the handle bottom portion is not limited to a fixed structure, and may be detachable from the handle bottom portion.

  The knife body in the present invention may be the same as that used for many years. That is, in the process of making a fish body, which is a raw material for salmon, it has been a blade knife, which is a knife for sowing fish, that has been usually used by workers. Therefore, also in the present invention, as a knife body provided with a blade and a handle portion to which the blade is connected, a cutting blade knife is assumed.

  Normally, a blade of a Japanese knife such as a knife with a knife can be used for many years while sharpening the cutting edge, so the scraping member has a bristle material in the case of a brush member and a protrusion in the case of a scale member. Wear and damage occur and deteriorate in a relatively short time. Accordingly, when the scraping member is detachably attached, only the deteriorated member can be replaced and the knife main body can be used without any problem.

  As the detachable attachment of the scraping member to the handle bottom part, a configuration in which locking means that can be releasably locked to the attachment part of the scraping member and the handle bottom part is simple. In the case where the scraping member is attached to the handle bottom portion via such a locking means, an existing knife can be used as it is as a knife body. Although various means can be considered as the locking means, it is desirable that the mechanism does not increase the cost with a relatively simple configuration. Examples thereof include a bolt / nut mechanism and a screwing mechanism.

  Specifically, in the case of locking means by a bolt and nut mechanism, a through hole is provided in the handle bottom part, and a cylindrical part that can insert the end of the handle part on the attachment side of the scraping member is provided integrally, If a through hole is formed at a position overlapping with the through hole of the handle bottom part also inserted into the cylindrical part, a scraping member is formed by inserting a bolt into the overlapped through hole and stopping with a nut. Can be detachably attached to the handle bottom part and can be exchanged.

  Further, in the case of the locking means by the screwing mechanism, male thread processing is directly applied to the outer peripheral area of the end portion of the handle bottom part or the female thread shape part is fixed, and the inner part of the cylindrical part integrally provided on the scraping member mounting side If the wall surface is subjected to internal thread processing that engages with the external thread, or the external periphery of the cylindrical portion is configured to perform external thread processing that engages with the internal thread shape portion, the scraping member is removably screwed into the handle bottom portion. Can be installed.

  Furthermore, if the locking means as described above are made common, not only the same kind of scraping members are exchanged, but also between different members, that is, the brush member and the scale member with respect to the same knife body. Optionally, it can be mounted interchangeably.

  For example, in a large amount of salmon fish processing process, there is a case where everything from the scale work to the fish collection work is continuously performed for each worker. It can be considered that the process is divided into the second half process including the work of removing the slag and performed in a flow work. And the case where a change arises with the case where the same worker performs the first half process and the second half process is also considered. In such a case, the brush member and the scale member can be selectively exchangeably attached to the same knife body that the operator is familiar with according to the required work process.

  As a first embodiment of the present invention, FIG. 1 shows a knife with a brush member fixed to the handle bottom. FIG. 1 is a schematic side view showing the overall configuration of the knife of the present embodiment. The knife 1 according to the present embodiment includes a knife body 2 in which a blade 3 for a blade knife is connected to a handle portion 4, and a brush member 10 fixed to the handle bottom portion 5. The brush member 10 has the most common brush head form in which a brush bristle material 12 made of a chemical fiber is uniformly implanted in a flat flocking table 11 curved in the longitudinal direction. In this brush member 10, the flocking table 11 is fixed to the tail end of the handle bottom 5 on one end side in the longitudinal direction. For example, the fixing is performed by inserting an adhesive into an insertion hole formed in the tail end of the handle bottom portion 5 as an attachment portion 13 in which one end of the flocking table 11 is elongated, and fixing the adhesive. Yes.

  The flocking table 11 in this embodiment is configured such that the central axis Y in the vicinity of the handle bottom 5 in the longitudinal direction of the flocking table 11 has a predetermined angle α with respect to the center axis X of the handle 4. The angle α is an angle range in which the scraping work by the brush bristle material 12 can be satisfactorily performed when the handle portion 4 is gripped. In this embodiment, the angle α is 30 ° to 60 °.

  In this knife 1, as shown in FIG. 2 (a), from the knife use state A in which the blade 3 is directed to the fish body, by simply returning the wrist without releasing the knife, the kidney removal with the brush member 10 directed to the fish body. It is possible to quickly switch to the scraped state B for performing. In the scraped state B, as shown in FIG. 2B, the kidney 102 can be scraped out from the fish body 100 with a relatively uniform scraping force by simply moving the wrist while rotating in the reverse hand state. Then, after the kidney removal process, it is possible to return to the state of use of the normal knife again by simply returning the wrist again.

  As a second embodiment of the present invention, FIG. 3 shows a knife in which a brush member is detachably attached to a handle bottom portion via a locking means. FIG. 3 is a longitudinal sectional view showing the structure of the locking portion, where (a) is a state before the brush member is mounted, and (b) is a state after the brush member is mounted, omitting the blade portion of the knife body. It is the shown schematic side view. In this embodiment, a case where a bolt / nut mechanism is provided as a locking means is shown. The brush form itself is the same general type as the first embodiment.

  That is, the through hole 6 is formed in the handle bottom part 5 of the handle part 4 of the kitchen knife body, while the brush member 20 is provided with a cylindrical locking part 24 on the opposite side to the head part. . The tubular locking portion 24 has an inner shape into which an end portion of the handle portion 4 including the handle bottom portion 5 is fitted, and a flocking table 21 in which a brush bristle material 22 is embedded on the outer bottom surface is at one end portion. They are connected together. A through hole 25 is also formed in the cylindrical locking portion 24.

  In the fitted state of the end of the handle portion 4 to the cylindrical locking portion 24, the through hole 6 of the handle bottom portion 5 and the through hole 25 of the cylindrical locking portion 24 can overlap with each other. 25), the bolt 26 is inserted, and the nut member 27 is tightened from one end thereof, whereby the brush member 20 can be attached to the handle bottom portion 5 via the cylindrical locking portion 24. When the nut 27 is loosened and the bolt 26 is extracted, the cylindrical locking portion 24 can be removed from the handle bottom portion 5, so that the brush member 20 that has deteriorated with use can be replaced with a new one.

  As a third embodiment of the present invention, FIG. 4 shows a knife in which a brush member is detachably attached to a handle bottom portion by a screwing mechanism. 4A and 4B are partial side views showing the structure of the locking portion, where FIG. 4A shows the state before the brush member is mounted, and FIG. 4B shows the state after the brush member is mounted without the blade portion of the knife body. FIG. Also in the present embodiment, the brush form itself is the same general type as the first embodiment.

  In the present embodiment, male threading is applied to the outer peripheral region of the handle bottom portion 5 of the handle portion 4 as the locking means. That is, the male screw portion 7 is directly formed on the handle bottom portion 5. On the other hand, the brush member 30 is provided with a cylindrical locking portion 34 into which the end portion of the handle portion 4 is fitted on the opposite side of the head portion. A flocking table 32 in which the brush bristle material 31 is embedded is integrally connected to the outer bottom surface of the cylindrical locking portion 34 at one end thereof. A female screw part 35 that is screwed into the male screw part 7 of the handle bottom part 5 is formed on the inner wall surface of the cylindrical locking part 34.

  Accordingly, by fitting the cylindrical locking portion 34 to the end portion of the handle portion 4 while screwing the female screw portion 35 into the male screw portion 7, the brush member 30 is handled via the cylindrical locking portion 34. It is screwed and attached to the butt 5. Therefore, if this screwing is loosened and the cylindrical locking portion 34 is removed from the male screw portion 7, the brush member 30 can be removed from the handle bottom portion 5 and replaced with a new brush member 30.

  In the above embodiment, the case where the brush member is provided in the most general form in which the brush bristle material is uniformly embedded in the flat flocking table is shown, but the present invention is limited to this. Instead, various brush forms can be employed.

  For example, as shown in FIG. 5, there is a brush member 40 in which brush bristle materials 42 are implanted substantially radially on a flocking table 41 having an arcuate flocking surface. The brush member 40 is attached to the handle bottom portion 5 via a locking portion 44 (the locking mechanism is not shown) to which the tip portion of the shaft portion 43 extending from the flocking table 41 is connected. By the substantially radial flocking of the bristle material 42, it is not necessary to consider the inclination angle with respect to the central axis of the handle part 4 and the shaft part 43 as in the above brush member having a flat flocking table. is there.

  Further, even when a torsion-like torsion brush type as shown in FIG. 6 is used, it is not necessary to consider the inclination angle, and the design is simple. In this case, the brush member 50 is obtained by twisting a brush bristle material 52 with a plurality of wires such as wires as the flocking table 51. The wire rod is further bent to join the ends to each other, thereby obtaining a substantially ring-shaped brush form. By fixing the shaft portion 53 on which the connecting portion between the ends of the wire rods is fixed to the locking portion 54 (the locking mechanism is not shown) with respect to the handle bottom portion 5, the locking portion 54 is fixed. The ring-shaped brush member 50 is detachably attached to the knife body, that is, exchangeable.

  As described above, when the kidney removal work is performed by returning the wrist of the knife with the brush member fixed or attached to the knife body to the scraped state B of the reverse hand, the direction of the brush is fixed in one direction. Has been. In the first embodiment shown in FIG. 1, the brush member 10 is fixed so that the tip direction of the brush bristle material 12 is substantially in the direction in which the blade edge of the blade body 3 faces. Therefore, the angle of the brush that hits the fish body 100 when the scraped state B is set without the picking up of the knife is also determined by this fixed state.

  This angle is not necessarily optimal for scraping work for all workers. However, the wrist can be adjusted to an angle at which it is easy to work by only slightly turning the wrist around the central axis of the knife toward the proximal side or the distal side of the body. However, a brush head angle adjusting means may be provided so as to cope with a case where a larger angle adjustment is desired.

  The angle adjusting means is preferably as simple as possible and the related member can be light. Specifically, as shown in FIG. 7, the flocking table 11 is attached to the tail end of the handle bottom part 5 via the shaft part 23, so that the flocking table 11 can be rotated around the axis of the shaft part 23. A connecting portion 15 to be connected may be provided, and the connecting portion 15 may be provided with an angle adjusting mechanism. For example, if a rotary joint incorporating a ratchet mechanism is used as the connecting portion 15, it is possible to change the angle of the flocking table 11 around the central axis in the shaft portion 23 at every angular interval where the ratchet pawl is provided. .

  Further, in the above embodiment, the case where the brush member is attached to the knife body as the scraping member has been described as an example. However, the present invention is not limited to this, and as shown in FIG. A case where the member 60 is attached is also conceivable.

  In this case, the scale member 60 is made of metal, and includes a scale head 61 on which a plurality of protrusions 62 are formed, and a shaft portion 63 that is integrally extended from the head at a predetermined angle. The tip of the shaft 63 is fixed to the tail end of the handle portion 4 of the kitchen knife body. If such a scale member 60 is also provided with a cylindrical locking portion as shown in FIGS. 3 and 4, the scale member 60 can be detachably attached to the knife body 2 and exchangeable with a brush member. .
