Abstract

<P>PROBLEM TO BE SOLVED: To meet the demand for improvement of enabling adductor muscle to be easily and rapidly taken out from shells. <P>SOLUTION: The shellfish-treating method for opening the shells 2 by separating the shell 2a from meat (the adductor muscle) 3 by jetting fluid to the inside of the shells 2 of the shellfish 1 from the outside of a nonstriated muscle part 60 of the shellfish 1 involves enabling the position, the angle or the like of a nozzle jetting the fluid to be changed according to the size of the shellfish 1 so that the fluid may be jetted to the nonstriated muscle part 60. Accompanying parts 4 such as digestive caecum of the shellfish 1 are sucked and removed separately or in a lump of two or more kinds after opening the one shell 2a of the shellfish 1. Further an opening part 5 is formed at a part of the shells 2 of the shellfish 1 so that the accompanying parts 4 of the shellfish 1 may be sucked and removed from the opening part 5. The position, the angle or the like of the nozzle 32 jetting the fluid can be changed according to the size of the shellfish 1 so that the fluid may be jetted to the nonstriated muscle part 60 when separating the other shell 2b from the meat 3 after sucking and removing the accompanying parts 4. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

  The present invention relates to various shellfish shells such as scallop shells and coral shells, and a shell processing method for removing associated parts such as strings and orchids from the shell, and a shell processing apparatus used therefor, for example, scallop shells. It is suitable for automatically removing scallops and associated parts from their shells (without applying heat) prior to shipping them to the market.

Shellfish such as scallops, sea bream, and oysters are shipped to the market in various product forms. In the case of scallops, for example, there are the following product forms.
1. Raw products with shells.
2. A raw product that opens and removes one shell, removes the midgut gland (commonly known as uro), and leaves scallops, orchids, straps, etc. in the other shell.
3. Raw products with only accessory parts such as gonad (common name, orchid), mantle (common name, string), heart, heel, and tentacles.
4). Products with only raw scallops (also known as closed shell muscles).
5. Products with only raw orchids (however, orchids can only be spawned).
6). Products with only raw strings and strawberries.

  For items other than products that are shipped to the market with shells, orchids, strings, scallops, etc. must be removed from the shells. When the take-out operation is performed manually, it takes a lot of labor and time. Therefore, in order to perform it efficiently in a short time, a method for automatically opening the shell and taking out the shell pillar has been developed. As one of them, the present applicant has developed a shell processing method shown in Patent Document 1 and a shell processing apparatus used therefor. They are the following methods.

  A part of the scallop shell that is fixed and transported on the tray of the transport body is cut and removed with a blade to form an opening, and fluid ejected from the nozzle of the first separation mechanism at high pressure from the opening It is sprayed along the inner surface of the upper shell, and the shell is removed from the upper surface of the shell post (opens the shell) by hitting the attachment part between the shell (shell) and the shell. The shell is ejected from the outside of the non-striated muscle portion along the inner surface of the shell toward the attachment portion between the shell pillar and the shell, and the shell is removed from the top surface of the shell pillar (the shell is opened). Thereafter, the accompanying parts such as uro, run, and string attached to the lower shell are removed by suction with the accompanying part suction removing mechanism (suction device), and then ejected at high pressure from the nozzle of the second separation mechanism. The fluid is sprayed along the inner surface of the lower shell and is applied to the adhesion portion between the shell and the scallop to separate the scallop from the shell. Also in this case, the fluid is ejected from the nozzle from the outside of the shellless muscle portion of the shell along the inner surface of the shell toward the attachment portion of the shell column and the shell, so that the shell is easily detached from the lower surface of the shell column.

JP 2002-218904 A.

  There is no particular problem with the shell processing method and the shell processing apparatus used therefor, but if it is strong, the position of the shell pillar in the shell and the part of the non-striated muscle portion differs depending on the size of the shell, In some cases, it is difficult to reliably inject the fluid to the non-striated muscle, and it is difficult to peel the shell smoothly from the shell post.

  The present invention, regardless of the size of the shell, it is difficult to scratch the shell of the shell (shell), the shell is difficult to chip, torn, and can be removed cleanly, easily and quickly without being damaged, In addition, the present invention provides a shell processing method and a processing apparatus that are hygienic and can take out shell pillars, strings, orchids according to a desired product form.

  The shell processing method of the present application is a shell processing method in which a fluid is sprayed from a fluid spray nozzle 25 to an adhesion portion between the shell pillar 3 and the inner surface of the shell 2a from the outside of the shell 1, and the shell 2a and the shell pillar 3 are separated. Before the jetting, the size of the shell 1 is measured, and the position and jetting angle of the fluid jet nozzle 25 are adjusted according to the measured size of the shell 1, and the fluid from the fluid jet nozzle 25 is removed from the shell 3 It sprays from the adhesion part side of the muscle part 60 and the shell 2a, the shell pillar 3 is peeled from the striped muscle part 60 side to the striped muscle part 65 side, the shell 2a and the shell pillar 3 are separated, and the shell pillar 3 is shell 2a. I was able to separate from. Further, after opening one shell 2 a of the shell 1, the fluid from the fluid jet nozzle 32 is sprayed from the side where the other shell 2 b and the stripless muscle portion 60 of the shell pillar 3 are attached, so that the shell 3 is not stripped. The shell pillar 3 was detached from the shell 2b by peeling off from the 60 side to the striped muscle portion 65 side and separating the shell 2b and the shell pillar 3 from each other. After the shell 2a is opened, the associated part 4 such as the midgut gland (common name, uro), gonad (common name, orchid), mantle (common name, string), heart, fold, and tentacles of the shell 1 are individually or two kinds. The above is collectively or entirely removed. Further, before removing one shell 2a of the shell 1, one or more shells 2a or both shells 2a, 2b are cut with a blade, or a hole is made or damaged by pressurization. Thus, the opening 5 can be formed, and the accompanying portion 4 can be removed by suction from the opening 5. The fluid is ejected from the opening 5 to the side where the shell 2a and the non-striated muscle 60 are attached to separate the shell 2a from the scallop 3, and then the accompanying portion 4 is removed by suction. It is also possible to separate the shell 2b from the scallop 3 by ejecting a fluid from the attachment portion side of the muscle portion 60. Debris, powder, etc. of the shell 2 generated by forming the opening 5 are removed by suction or flushing with a fluid.

  The shell processing apparatus of the present application is a shell processing apparatus that separates the shell 2a and the shell pillar 3 by injecting a fluid from the fluid spray nozzle 25 to the attachment portion between the shell pillar 3 and the inner surface of the shell 2a from the outside of the shell 1. A measuring device 70 that measures the size of the shell 1, a fluid ejection nozzle 25, and an adjustment mechanism 71 that adjusts the position and ejection angle of the fluid ejection nozzle 25 according to the measured size of the shell 1. The mechanism 71 adjusts the fluid ejecting nozzle 25 so that the fluid ejected from the fluid ejecting nozzle 25 is ejected to the adhesion portion side between the inner surface of the shell 2 a and the non-muscle portion 60 of the shell 3. Further, a second adjusting mechanism 74 that individually adjusts the position and the injection angle of each of the second fluid injection nozzles 32 is provided, and the fluid adheres to the inner surface of the other shell 2b and the non-striated muscle portion 60 of the shell pillar 3. It was made to be injected to the part side. Moreover, the opening part 5 can also be formed in one place or two places or more of the shell 2 of one or both of the shells 1. Further, an accompanying part suction removing mechanism 10 for sucking and removing the accompanying part 4 may be provided. In addition, an accompanying portion removing fluid ejecting mechanism for removing the accompanying portion 4 from the shell by fluid ejection may be provided separately from the first or second fluid ejecting nozzle, or may be used in combination with one or both of them. The conveyance body 11 can also be a conveyor type or a turntable type.

The shellfish processing method of the present invention has the following effects.

It is possible to spray fluids aiming at the muscular muscles of shells, and easily and quickly separate shells of various sizes from shells even at low pressures. It becomes difficult to collapse or damage, and the original shape is secured. In addition, work efficiency is further improved.
(2) Since the fluid is used for removing the shell and the scallop, the scallop is hardly damaged.
(3) Since the scallops are not heated at all, the scallops can be taken out without deterioration in quality and are traded as biological products on the market.
(4) Since the shell pillar is washed with the fluid even if the shell fragments, chips, powder, etc. attached to the shell pillar are attached, the shell pillar with no chips attached can be taken out.
(5) Since the accompanying part is removed by suction or fluid ejection, the accompanying part can be easily and reliably removed. Moreover, since the accompanying part is not damaged, the commercial value of the accompanying part is not lowered.
(6) Since the shell is separated by a fluid and the accompanying part is removed by suction or fluid jetting with a suction device, the shell does not need to touch the shell post and the accompanying part after the shell is placed on the transport body, and is hygienic. .

The shell processing apparatus of the present invention has the following effects.

(Embodiment 1 of shellfish processing method)
One example of the embodiment of the shell processing method of the present invention will be described in detail with reference to FIGS. This embodiment is a case where the shellfish 1 is a scallop shell provided with two shells 2a and 2b, and relates to a method for taking out a shell pillar and an accompanying portion.

  In this embodiment, as shown in FIGS. 1A and 2, the shell 1 is placed on the tray 20 of the transport body 11 and transported. The operation of placing the shell 1 on the tray 20 can be performed manually or automatically by a machine. In this case, the orientation of the shell 1 and the top and bottom of the shell 1 are made uniform. For example, the connecting side 21 (FIG. 1A) where the two shells 2 a and 2 b of the shell 1 are connected is aligned in the same direction in the width direction of the transport body 11. Usually, it may be set with a flat shell (brown shell: right shell) called the upper shell facing down, and conversely, a deep shell (white shell: left shell) ) May be set downward.

  The shell 1 placed on the saucer 20 is transported by the transport body 11, and when transported to a predetermined position, as shown in FIG. 3 (a), a holding tool 22 using a belt conveyor disposed above the transport body 11. And is sandwiched between the holder 22 and the tray 20 of the transport body 11. The carrier 11 and the holder 22 intermittently travel at the same speed, and are stopped and started in synchronization. When the shell 1 is transported over the blade 23, the transport body 11 and the holding tool 22 are stopped, and the connection side 21 and the tip side 24 of the lower shell 2b are stopped as shown in FIG. The opening 5 is formed by being cut and removed by the single blade 23. Thereafter, the transport body 11 and the holder 22 start traveling in synchronization, and transport the shell 1 on the tray 20. When the shell 1 is transported to the vicinity of the first nozzle 25 of the first removal mechanism 13 (FIG. 1C, FIG. 4), the transport body 11 and the holder 22 are stopped.

  During the stop, the shell 1 is sucked and held in the tray 20 by the suction device built in the tray 20. When the shell 1 is held, as shown in FIG. 4, the size of the shell 1 on the tray 20 is measured by a measuring device 70 such as an optical sensor or a shape measuring device, and is provided in the first nozzle 25. The first adjusting mechanism 71 compares the measured size of the shell 1 with the average value of the position and size (see FIGS. 9 and 10) of the non-muscle portion 60 in the shell 3 of the shell 1 of that size. The position and size of the non-muscle portion 60 of the shell 1 are calculated, and the first adjusting mechanism is based on the calculated position and size of the non-muscle portion 60 of the shell 1 as shown in FIGS. 71, the arm 72 is moved by the position of the nozzle (jetting body) 25 of the first detaching mechanism 13 and the jetting angle from the non-muscle portion 60 side of the scallop 3 to the entire adhering portion of the scallop 3 and the shell 2a. Adjust so that can be injected. For example, as shown in FIG. 5, when the shell 1 is large, the distance between the first nozzle 25 and the shell 1 is increased, and when the shell 1 is small, the first nozzle 25 and the shell 1 are And the fluid 26 is adjusted so that the fluid 26 is diffused and jetted from the first nozzle 25 from the adhering portion side between the shell 2a and the non-muscle portion 60 of the shell 3. In this state, as shown in FIG. 4, a fluid 26 ejected at a high pressure from the first nozzle 25 of the first removal mechanism 13 is ejected from the opening 5 of the shell 2b along the inner surface of the upper shell 2a. 26 is applied from the side of the striated muscle portion 60 of the scallop 3 to the side where the scallop 3 and the inner surface of the shell 2a are attached, and the striated muscle portion 60 is peeled off from the shell 2a and the striated muscle portion 65 is peeled off accordingly. The shell 2a is removed from the scallop 3 (opens the shell). The fluid 26 can be any fluid such as water, seawater or other liquid, air, nitrogen, carbon dioxide gas or the like, or a gas such as air containing water. In this case, as shown in FIGS. 9 and 10, when the shell 2 a is sprayed from the outer side of the non-striated muscle portion 60 of the shell 1 along the inner surface of the shell 2 a toward the attachment portion of the shell pillar 3 and the shell 2 a, the shell 2 a is It becomes easy to peel off from the upper surface of the scallop 3, and the shell 2a is easily removed (the shell is easily opened). This is the same when removing either the brown shell (right shell) or the white shell from the shell 3.

  The measurement of the size of the shell 1 by the measuring device 70 is not limited to the time when the shell 1 is sucked and held in the tray 20, but the shell 1 is being transported by the transport body 11, the shell 1 is being cut by the blade 23, etc. It can also be done in advance. The first adjustment mechanism 71 is input with data such as the average value of the position and size of the non-striated muscle portion in the scallop of each shell size. The average value is calculated by multiplying the size of the measured shell shape by the ratio in the case of a shellfish whose size and position of shells and shells change with growth, such as scallops. can do.

Specifically, the first adjustment mechanism 71 calculates, for example, the position and size of the non-striated muscle portion 60 of the shell 1 as follows. This embodiment demonstrates the example in the case of scallops from Mutsu Bay, Hokkaido Funka Bay Morimachi, Tokoro, etc. As shown in FIGS. 9 and 10, the shell height of the shell 1 is H, the shell length is L, and the shell width is B. As shown in FIG. 60 both end points and their coordinates, respectively R ₀ of _{(x 0, y 0, z} 0), R 1 (x 1, y 1, z 1), and then, the middle point and the coordinates of the R ₀ and R ₁ Let R ₂ (x ₂ , y ₂ , z ₂ ). The measuring device 70 measures the shell height H, shell length L, and shell width B of the shell 1, and sends the numerical data to the first adjustment mechanism 71. In the first adjusting mechanism 71, the coordinates R ₀ (x ₀ , y ₀ ) of the two end points of the non-striated muscle portion 60 on the shell height-shell length plane (XY plane) and R ₁ (x ₁ , y ₁ ) is calculated by the following equations (1) to (4), and the position and size of the non-striated muscle portion 60 of the shell 1 are calculated.

Further, the first adjustment mechanism 71 is based on the position and size of the non-muscle portion 60 of the shell 1 calculated as described above, and the position and ejection angle of the first nozzle 25 are as follows. Is calculated. Here, the position at which the first nozzle 25 ejects the fluid 26 is P (x _p , y _p , z _p ), and the intersection point between the jet axis of the fluid from the first nozzle 25 and the end of the shell 2a is Q. (X _q , y _q , z _q ), the dip angle of the nozzle ejection angle is θ, the elevation angle is φ, the tilt angle is ψ, and the central angle of the jet flow from the first nozzle 25 is α (not shown). And The adjustment mechanism 71 uses the positions of R ₀ , R ₁ , R ₂ , and Q determined by determining the position of the shell 1, and uses the following formulas (5) to (10) to inject the injection position P ( x _p , y _p , z _p ), the dip angle θ, the elevation angle φ, and the tilt angle ψ that determine the injection angle of the first nozzle 25 are calculated.

  The structure and size of the first nozzle 25, the injection pressure (liquid pressure) of the fluid 26 injected from the first nozzle 25, the injection amount (liquid amount) of the fluid 26 injected from the first nozzle 25, etc. Can be arbitrarily selected. For example, as the first nozzle 25, a nozzle having a horizontally long injection port 61 as shown in FIG. 11A is suitable, the liquid pressure is 200 kg / cm 2, and the liquid volume is about 6.0 l / min. Can do. The 1st nozzle 25 is not restricted to what is shown to Fig.11 (a), It can also be set as the circular injection nozzle 61 as shown in FIG.11 (b). In this case, a rod-shaped fluid is ejected from the ejection port 61, and the first nozzle 25 is swung to eject the fluid from the non-striated muscle portion 60 side to the shell pillar 3. The ejection of the fluid 26 is not limited to the opening 5 but can be performed from another location. For example, the first nozzle 25 is inserted from the gap between the upper and lower shells slightly inside the butterfly (ligament) of the shell 2, and fluid is ejected from the outside of the non-striated muscle portion 60 of the shell 1, or other locations. The first nozzle 25 can be inserted and ejected. The ejection angle of the fluid from the first nozzle 25 can be arbitrarily selected.

  In the illustrated example, the number of the first nozzles 25 is one, but a plurality of nozzles are arranged on the outer periphery of the shell 1, and the fluid 26 sprayed from them is disposed along the inner surface of the shell 2 a along the unstriped portion of the shell pillar 3. The shell pillar 3 and the shell 2a are separated from each other by being applied to the attachment portion side of the shell 60a and the shell 2a from multiple directions, or the first nozzle 25 is swung or rotated in the outer peripheral direction of the shell pillar 3 to The shell 26 and the shell 2a are separated from each other by, for example, applying the fluid 26 sprayed from the nozzle 25 along the inner surface of the shell 2a along the inner surface of the shell pillar 3 to the non-striated muscle portion 60 of the shell pillar 3 and the shell 2a. You can also In this case, when the fluid 26 is formed into a high-pressure thin jet, the shell 3 and the shell 2a are easily separated. When the upper shell 2a is opened, the transport body 11 resumes traveling and transports the shell 1. When the shell 1 is transported to the vicinity of the accompanying portion suction removal mechanism (suction device) 10, the transport body 11 stops again.

  During the stop, the lower shell 2 b is pressed against the tray 20 by the first holder 27 and held by the tray 20 as shown in FIGS. In this state, the suction port 28 of the accompanying portion suction removing mechanism (suction device) 10 is brought close to the lower shell 2b to which the shell pillar 3 is attached, and the accompanying portions 4 such as the uro 45, the run 46, and the string 47 shown in FIG. Remove by suction. The sucked incidental part 4 is introduced into the tank 30 through the discharge passage 29, and moisture, fine dust, etc. contained in the incidental incidental part 4 pass through the filter 31 in the tank 30 and are stored in the tank. 30 is discharged to the outside. The accompanying portion 4 accumulated in the tank 30 is classified according to the type of uro, string, orchid, etc. as necessary, uro is discarded, and edible things such as string and orchid are post-processed and provided for edible use. . When removing the appendage 4 from the shell 2b, only the scale is removed and discarded, the remaining appendage 4 is removed and commercialized, or the string and the bag are removed together. It is possible to remove the accompanying parts 4 individually, in a group of two or more, or all together.

  When suction removal of the accompanying part 4 is completed as described above, the transport body 11 resumes running, and the shell 1 from which the accompanying part 4 has been removed is the second removal mechanism 14 of FIG. 1 (e) and FIG. When transported to the vicinity of the second nozzle 32, the transport body 11 stops again. During this stop, the lower shell 2 b is pressed against the tray 20 by the second holder 33 and is held by the tray 20. When the shell 1 is held, as in the case of the first removal mechanism 13, as shown in FIG. 7, the size of the shell 1 on the tray 20 is measured by a measuring device 73 such as an optical sensor or a shape measuring device. The size of the shell 1 measured by the second adjustment mechanism 74 provided in the second nozzle 32 and the position and size of the striated muscle portion 60 in the shell pillar 3 of the shell 1 of that size (see FIG. 9 and 10), the position and size of the non-striated muscle portion 60 of the shell 1 are calculated, and the arm 75 is moved by the second adjusting mechanism 74 as shown in FIGS. Move the second nozzle (jetting body) 32 of the second detaching mechanism 14 so that the position and the jetting angle of the second nozzle (sprayer) 32 are applied to the entire inner surface of the shell 3 and the shell 2b, and the fluid 34 is fed from the non-striated muscle 60 side of the shell 3 Change it so that it can be injected. For example, as shown in FIG. 5, when the shell 1 is large, the distance between the second nozzle 32 and the shell 1 is increased, and when the shell 1 is small, the second nozzle 32 and the shell 1 are And the fluid 34 is adjusted so that the fluid 34 is diffused and jetted from the second nozzle 32 from the side where the shell 2b and the non-muscle portion 60 of the shell 3 are attached. In this state, as shown in FIG. 6, the fluid 34 ejected from the second nozzle 32 of the second removal mechanism 14 at a high pressure along the inner surface of the lower shell 2b, The striated muscle portion 60 is peeled off from the shell 2b and applied to the inner surface of the shell 2b, and the striated muscle portion 65 is peeled off at the same time, and the scallop 3 is removed from the shell 2b. As the fluid 34, any fluid such as water, seawater or other liquid, air, nitrogen, carbon dioxide gas or the like, or a gas such as air containing moisture can be used. At this time, when the scallop suction device 35 is brought close to the bottom of the scallop 3 and the scallop 3 is sucked upward as shown in FIG. 7, the scallop 3 separated by the fluid is easily separated from the lower shell 2b. Also in this case, as shown in FIG. 9 and FIG. 10, the fluid from the second nozzle 32 is directed from the outside of the shell 1 along the inner surface of the shell 2 b toward the portion where the stripless muscle portion 60 of the shell pillar 3 and the shell 2 b are attached. When 34 is ejected, the shell 2 b is easily detached from the bottom surface of the shell pillar 3. Also in this case, the ejection angle of the fluid from the second nozzle 32 can be arbitrarily selected. The number of the second nozzles 32 can also be arbitrarily selected.

  Moreover, in the 2nd removal mechanism 14, the numerical value of the magnitude | size of the shell 1 measured in the measurement apparatus 70 of the previous 1st removal mechanism 13 can also be used, without providing the measurement apparatus 73. FIG. Similarly to the first removal mechanism 13, the second adjustment mechanism 74 is input with the average value of the position and size of the non-striated muscle portion in the shell pillar of each size of each shell. Specifically, the second adjustment mechanism 74 performs the same calculation and control as the first adjustment mechanism 71.

  The scallop 3 separated from the shell 2 b is sucked by the scallop suction device 35 and sent out of the transport body 11. After this scallop 3 is washed with a washing solution, it is shipped as it is or after being frozen. Ordinary water, ozone water, UV treated water, or the like can be used as the cleaning liquid.

  The shellfish processing method of the present invention is not limited to the case where the shellfish 1 is a scallop shell provided with two shells 2, but is a case of other shellfish such as a mussels or a shell shell provided with one shell such as a salmon. Can also be implemented.

  The removal of the associated part 4 is not limited to the suction removal by the associated part suction / removal mechanism 10 described above, and can be removed by removing it from the shell by fluid ejection. In that case, a fluid ejecting mechanism for removing the accompanying part capable of ejecting fluid for removing the accompanying part 4 is provided instead of the accompanying part suction removing mechanism 10 or in addition to the accompanying part suction removing mechanism 10. Can do. Further, instead of separately providing the accompanying part removing fluid ejecting mechanism, one or both of the first nozzle 25 and the second nozzle 32 can also serve as the accompanying part removing fluid ejecting mechanism.

(Embodiment 2 of shellfish processing method)
Another example of the embodiment of the shellfish processing method of the present invention will be described in detail with reference to FIGS. The shell processing method of this embodiment also has a basic embodiment in common with the first embodiment. Also in this embodiment, the shell 1 is transported by the transport body 11 as shown in FIG. 8A, and the shell 2b is cut by the blade 23 as shown in FIG. As shown in (c), the upper shell 2a is removed from the scallop 3 by fluid pressure. However, in this embodiment, after that, by the accompanying portion suction removal mechanism 10, first, the scale 45 as shown in FIG. 8D, the run 46 as shown in FIG. The difference from the first embodiment is that the string 47 is sucked and removed separately in order as in f). Thereafter, as shown in FIG. 8G, the lower shell 2b is removed from the scallop 3 with a fluid pressure in common with the first embodiment. In FIG. 8, for convenience of explanation, the scale 45 and the run 46 are displayed at positions shifted by 180 degrees, but the scale 45 and the run 46 are actually positioned at positions shifted by approximately 90 degrees on the outer periphery of the shell 3 as shown in FIG. . 8 (d) to 8 (f), the accompanying portion suction removing mechanism 10 for sucking and removing the urine 45 and the accompanying portion suction removing mechanism 10 for sucking and removing the run 46 are used together. 8 (d) and (e), 90 degree reciprocal rotation is possible. Further, when the accompanying part suction removal mechanism 10 sucks and removes either the euro 45 or the run 46, it automatically rotates 90 degrees and the other is rotated. The suction is removed. However, the order of suction removal using the accompanying portion suction removal mechanism 10 is not limited to the above-described order of the scale 45, the run 46, and the string 47, and the suction removal can be performed in an arbitrary order.

  A color discrimination sensor 48 is attached to the apparatus shown in FIG. The sensor 48 can discriminate the color of the run 46 and discriminate whether the run 46 is a male shell or a female shell. By the way, male orchids are white and female shells are red. This color discrimination is convenient because the orchid 46 can be post-processed separately for male shells and female shells.

(Embodiment 1 of shellfish processing apparatus)
An example of an embodiment of a shell processing apparatus used for carrying out the shell processing method of the present invention will be described in detail with reference to FIGS. As shown in FIGS. 1A to 1E, the shell processing apparatus of the present invention includes a transport unit, a cut unit, a fluid pressure cutter unit (upper shell), a scale removing unit, and a fluid pressure cutter unit ( Lower shell).

  As shown in FIG. 3, the transport body 11 of the transport section in FIG. 1A is configured by mounting a tray 20 on a traveling body 36 such as a chain or other belt, and the tray 20 has a pair of two receiving pieces 37. A semicircular arc-shaped concave curved portion 38 is formed on the upper surface of each receiving piece 37, and each receiving piece 37 is attached to the traveling body 36 so that the concave curved portion 38 faces each other. The transport body 11 automatically stops when it reaches a predetermined position, and automatically starts to travel after a predetermined time, and intermittently travels by a certain distance. The traveling body 36 of the transport body 11 is not limited to that shown in the figure, and an arbitrary one such as an endless conveyor or a turntable can be used.

  1 (b) and FIG. 3 has an endless belt-like holder 22 and a lower traveling portion 40 (FIG. 1 (b) and FIG. 3 (a)) on the inner side of the holder 22 below. A pusher 41 for pushing is arranged. The pusher 41 is disposed at a position facing the saucer 20 with the lower traveling portion 40 of the holder 22 interposed therebetween so that the shell 1 on the saucer 20 can be sandwiched and held between the saucer 20. . A spring 42 is disposed on the outer periphery of the shaft of the holding tool 22, and the spring 42 pushes the pressing tool 41 downward, and the shell on the tray 20 below the lower running portion 40 of the holding tool 22. When 1 enters, it is pushed back up.

  1 (b) and FIG. 3 is a disc-shaped diamond cutter, which is disposed on both outer sides in the width direction of the transport body 11, and is rotated by a driving device (not shown). is there. For the blade 23, a cutter made of another material suitable for cutting the shell 2 or a cutter having another shape can be used. The blade 23 may be always rotated, or may be rotated only at the time of cutting. Moreover, the position and space | interval of the two blades 23 can also be changed according to the magnitude | size and shape of a shellfish.

  1 (c) (e), FIG. 4 and FIG. 7, the measuring devices 70 and 73 of the hydraulic cutter unit use devices such as an optical sensor and a shape measuring device, and the size of the shell 1 on the tray 20 is determined. It can be measured. In addition, the adjusting mechanisms 71 and 74 shown in the figure incorporate a computer or the like built in the shell processing apparatus of the present invention. The adjustment mechanisms 71 and 74 are average values of the size of the shell 1 measured by the measuring devices 70 and 73 and the position and size of the striated muscle portion 60 in the shell pillar 3 of the shell 1 of that size (see FIGS. 9 and 10). The position and size of the non-striated muscle portion 60 of the shell 1 are calculated by comparing with the data such as the above, and the arm 72 (75) is moved by the adjusting mechanism 71 as shown in FIGS. The position, angle, spraying posture, etc. of the body) 25 (32) can be changed so that fluid can be sprayed from the non-muscle muscle portion 60 of the shell pillar 3 and the attached portion side of the inner surface of the shell 2a. In the adjustment mechanisms 71 and 74, the average values of the positions and sizes of the non-striated muscles in the shell pillars of various sizes are input.

  The nozzles 25 and 32 shown in FIGS. 1C, 1E, 4, 7, 8C, and 8G can have any shape as long as fluid can be ejected. As shown to (a), what was provided with the horizontally long injection nozzle 61 is suitable, a liquid pressure can be 200 kg / cm <2> and a liquid quantity can be about 6.0 l / min. Further, the position of the nozzles 25 and 32 and the injection angle are changed according to the size of the shell, so that the fluid can be jetted from the side of the non-muscle muscle 60 of the shell 3 to the attached portion of the inner surface of the shell 3 and the shell 2. Therefore, it is desirable that the fluid can be diffused and ejected as shown in FIG. The shape of the nozzles 25 and 32 is not limited to that shown in FIG. 11A, and a circular injection port 61 as shown in FIG. In this case, a rod-shaped fluid is ejected from the ejection port 61, and the nozzle is swung to eject the fluid to the shell pillar 3. Further, the number and positions of the nozzles 25 and 32 are not limited to those shown in the figure, and may be arbitrary.

  1 (d), the one shown in FIG. 6 as a holding mechanism for the shell 1 has two arm-shaped first holding tools 27 arranged on both outer sides of the tray 20, and the holding tool 27 is When closed inward by a driving device (not shown), an inward locking piece 43 at the upper end of the holder 27 is locked to the upper edge of the lower shell 2 placed on the receiving tray 20, and the shell 2 is The holder 27 is pressed against and held by the tray 20, and when the holder 27 is opened outward by the driving device, the locking piece 43 of the holder 27 is released from the upper edge of the lower shell 2 so that the pressing to the tray 20 is released. Is. Other holding mechanisms may be used.

  1D, a vacuum suction device is used for the suction mechanism 50 of the accompanying portion suction removal mechanism 10 as shown in FIG. The suction mechanism 50 evacuates the inside of the discharge path 29 and the accompanying part suction removing mechanism (vacuum nozzle) 10 by the operation of the vacuum pump 51, and the accompanying part 4 attaching the suction port 28 of the accompanying part suction removing mechanism 10 to the shell 2. , The associated part 4 is sucked and removed from the shell 2. The accompanying portion 4 sucked into the accompanying portion suction removing mechanism 10 passes through the discharge path 29 and is put into the tank 30. Moisture, fine dust, and the like contained in the associated portion 4 thrown into the tank 30 pass through the filter 31 in the tank 30 and are discharged to the outside of the tank 30. The accompanying portion 4 accumulated in the tank 30 is classified by type as necessary, and is used for other purposes or discarded. The first holder 27 is opened and closed left and right by a driving mechanism (not shown). When the associated portion 4 is removed from the lower shell 2, the first holder 27 is opened and the holding of the shell 2 is released.

  Although the suction port 28 of the accompanying portion suction removal mechanism 10 in FIG. 6 is formed in a ring shape, the suction port 28 may be a simple cylinder such as the scallop suction device 35 shown in FIG. Alternatively, it may be in the shape of an elongated hole or the like, and the hole size may be any size that facilitates suction of the associated portions 4 individually or simultaneously. Further, as shown in FIGS. 8D and 8E, a color discrimination sensor 48 can be attached to the accompanying portion suction removal mechanism 10. The sensor 48 can discriminate the color of the run 46 and discriminate whether the run 46 is a male shell or a female shell.

  In FIG. 1, the opening 5 is formed only in the lower shell 2, but the opening can be formed in both the upper and lower shells 2. The opening location may be other than the illustrated location. For example, two or more apertures can be opened at any location such as one end or both ends in the width direction of the shell 2. When two or more openings 5 are formed, the fluid ejected from one of the openings 5 escapes from the other opening 5, and the ejected fluid is less likely to accumulate inside the shell 2, causing damage to the shell 3 And it becomes difficult to get soaked in water.

  Although the disk-shaped rotary blade 23 is shown in FIG. 1, the cutter to be used may have another shape or other motion (for example, reciprocating motion). For example, a cylindrical blade can be rotated to open a round hole in the shell 2 to form the opening 5. Further, without using a blade, a heavy object such as a hammer can be dropped onto the shell 2 from above to break a part of the shell 2 to form the opening. In this case, it is desirable that the generated fragments, powders, and the like of the shell 2 are sucked and removed with a suction removing device while being cut, or washed away with a fluid (for example, water).

  In FIG. 1, the transport body 11 is intermittently moved and the shell 2b is cut by the rotary blade 23 when stopped. However, the transport body 11 is continuously traveled to form the opening 5 during travel, It can also be processed. In that case, it is set to a traveling speed at which work is easy.

  In FIG. 1, when the upper shell 2 a is separated from the shell pillar 3, the shell 1 on the tray 20 is sucked downward by the suction-type holding mechanism built in the tray 20 and can be held on the tray 20. However, it is convenient that the holding mechanism is automatically connected to the suction device installed at the stop position when traveling is stopped so that suction can be performed, and the suction device is automatically separated before the movement is started. is there. When a suction-type holding mechanism is built in the tray 20, if a suction device is installed at each stop position and the suction device is automatically connected to or separated from the holding mechanism, Even when the first holder 27 and the second holder 33 are not used at the time of each stop, the shell on the tray 20 can be sucked and held in the tray 20. In addition, a holding tool such as the first holding tool 27 and the second holding tool 33 can be provided in each step without incorporating the suction-type holding mechanism in the tray 20.

  In this embodiment, the upper shell 2a is opened and then the accompanying portion 4 attached to the lower shell 2b is removed by suction. In the present invention, the upper shell 2a is formed after the opening 5 is formed. Without opening, it is possible to apply the suction port (for example, nozzle) 28 of the accompanying portion suction removal mechanism 10 to the opening 5 and suck and remove only the scale 45 from the shell 1.

  In FIG. 1 (d), the entire associated part 4 such as uro, string, orchid is collectively sucked and removed by one accompanying part suction / removal mechanism 10, but the associated part 4 is composed of uro 45, run 46, string As shown in FIG. In particular, since the waste is discarded and the other parts are commercialized, it is desirable to suck and remove the scale 45 separately from the other parts. For this reason, a suction removal device and suction mechanism dedicated to removal of scales are provided, a suction removal device for straps, a suction removal device for runs, and the like. It can also be removed. Since orchids are not year-round and are only in the spawning season, they are removed by suction only at certain times.

  1 (c), (e), FIG. 4, FIG. 7, FIG. 8 (c) and (g), the nozzles 25 and 32 inject fluid from the outside of the non-striated muscle portion 60 of the shell 1 to the inside of the shell 2. The shell 2 and the body 3 can be separated from each other so that they are installed outside the shellless muscle 60 side of the shell 1. The installation position may be another place.

(Embodiment 2 of the shell processing apparatus)
Another example of the embodiment of the shell processing apparatus of the present invention will be described in detail with reference to FIGS. In the shell processing apparatus shown here, as shown in FIG. 12, a plurality of shell mounting bases 104 on which a shell 103 can be mounted (set) can be installed on a turntable 102 rotatably attached to a support column 101.

Further, on the transport path of the shell 103 by the turntable 102, a shell supply unit P that sets the shell 103 on the shell mounting base 104, and a shell detection part Q that detects whether the shell 103 is set on the shell mounting base 104. ₁ , an opening forming means A for forming an opening in the shell 103, an upper shell separating means B for separating the upper shell 103a and the shell pillar 105, an upper shell removing means C for removing the upper shell 103a separated from the shell pillar 105, Uro removal means D ₁ for sucking and removing uro 106a from the lower shell 103b, an accompanying part removing means D ₂ for sucking and removing the accompanying parts 106 other than uro such as run and string from the lower shell 103b, and the attached part 106 removed. Lower shell separating means E for separating the shell 103b and the scallop 105, scallop collecting means F for collecting the scallop 105 separated from the lower shell 103b, and removing the lower shell 103b after the scallop 105 is collected Lower shells discharge means G, shellfish 103 are sequentially provided shellfish detector Q ₂ to which detects whether discharged from the shell loading stand 104, drilled shell during transportation, associated part removing, scallop recovery, such as shells discharge series of the Processing can be performed automatically.

  The turntable 102 shown in FIG. 12 rotates intermittently in the direction of the arrow in the figure using an electric motor (not shown) as a drive source, and sequentially supplies the shells 103 set on the shell mounting base 104 to each means. Specifically, the rotation interval, rotation speed, rotation amount, and the like of the turntable 102 are set in advance, and each time the processing in each means is completed, the turntable 102 rotates by a predetermined amount and is processed by the preceding means. The shellfish 103 are sequentially supplied to the following means.

  As shown in FIG. 13, each shell mounting base 104 installed on the turntable 102 is provided with a pair of mounting portions 107, and two shells are provided for one shell mounting base 104. 103 can be set simultaneously. The shell 103 is set in the shell supply part P as shown in FIG. As shown in FIG. 14, each mounting portion 107 is formed of a flexible material (for example, synthetic resin) so as to have a substantially concave cross section, and a suction port 108 is opened at the center of the bottom surface. Further, a receiver tank 110 communicating with the suction port 108 is formed below each mounting portion 107, and one end of a pressure hose 111 communicating with a vacuum pump (not shown) is connected to the receiver tank 110. ing.

The shell detecting unit Q ₁ shown in FIG. 12 is provided with a sensor (not shown) so that it can detect whether or not the shell 103 is set on the shell mounting base 104.

Next, the operation of the shell mounting base 104 having the above configuration will be described. In the shell supply portion P, the shell 103 is set so that the lower shell 103b faces downward and the opening of the mounting portion 107 is closed by the outer surface of the lower shell. Next, the shell detecting unit Q ₁ detects whether or not the shell 103 is set on the shell mounting base 104 by a sensor, and when the shell 103 is detected, the switch 115 shown in FIG. It is moved in the direction of the arrow, and a vacuum pump (not shown) is operated to suck the shellfish 103 from the suction port 108. Then, the inside of the mounting part closed by the outer surface of the lower shell becomes negative pressure, and the shellfish 103 is sucked and held. At this time, dust or the like attached to the surface of the shell 103 is also sucked from the suction port 108, but the sucked dust or the like is stored in the receiver tank 110. The receiver tank 110 can also be provided with a discharge port for discharging collected dust and the like. In addition, as shown in FIG. 14, the plate 113 for positioning the shellfish 103 set there is set up by the back of the mounting part 107. As shown in FIG.

  A specific configuration of the opening means A shown in FIG. 12 is shown in FIG. The opening forming means A includes a cutter 120 that can cut the shells 103a and 103b of the shell 103, an electric motor 121 that is a driving source of the cutter 120, and a lifting piston 122 that lifts and lowers them between a standby position and a working position. And. Here, the cutter 120 includes a pair of front cutters 120a for cutting the tip portions 103c of the upper shell 103a and the lower shell 103b, and a pair for cutting the connecting portions 103d of the upper shell 103a and the lower shell 103b. And a pair of cutters 120a and 120b are arranged in parallel in the front-rear direction. In this processing apparatus, the two pairs of cutters 120 a and 120 b are arranged side by side so that openings can be simultaneously formed in the two shells 103 set on one shell mounting base 104.

  The cutter 120 is accommodated in a transparent case 123 having a lower opening, and a fluid supply nozzle (not shown) is provided in the case 123. This nozzle supplies a fluid for preventing generation of frictional heat at the time of cutting, scattering of chips, and the like. The electric motor 121 is installed on the case 123, and includes a drive pulley 124 attached to the rotating shaft thereof and a passive pulley 126 attached to a shaft 125 penetratingly fixed to the centers of the cutters 120a and 120b. Further, a transmission belt 127 is wound around. Therefore, when the motor 121 is operated, the rotational force is transmitted from the rotation shaft → the drive pulley 124 → the passive pulley 126 → the shaft 125, and the cutter 120 rotates in the direction of the arrow in the drawing. The rod 128 of the elevating piston 122 is connected to the case 123. As the rod 128 expands and contracts, the case 123 rises, and the cutter 120 in the case 123 and the motor 121 on the case 123 also rise. Further, the cutter 120a can be moved back and forth in the direction of the arrow shown in FIG. 15 according to the size of the shellfish.

  Next, the operation of the opening forming means A having the above configuration will be described. When the turntable 102 rotates and the shell mounting base 104 is fed below the case 123 (here, the turntable 102 stops once), the electric motor 121 is activated and the cutter 120 starts rotating. Then, in synchronization with the start of the rotation of the cutter 120, the rod 128 of the elevating piston 122 contracts to lower the case 123, and the rotating cutter 120 is lowered from the standby position indicated by the solid line to the work position indicated by the chain line. As a result, the front end portion 103c of the shell 103 set on each mounting portion 107 of the shell mounting base 104 is cut by the front cutter 120a, and the connecting portion 103d is cut by the rear cutter 120b. During this time, fluid is supplied from the fluid supply nozzle. As described above, an opening communicating with the inside of the shell 103 is formed at the tip of each shell 103, and the upper shell 103a and the lower shell 103b can be easily separated by cutting the connecting portion 103d. Become. When the cutting operation is completed, the electric motor 121 is stopped, and the rod 128 of the elevating piston 122 is extended in synchronization with this to raise the case 123 and return the cutter 120 to the standby position. Note that a slope 129 is installed under the turntable 102, and the tip portion 103c and the connecting portion 103d of the cut shell 103 fall on the slope 129 and slide on the slope 129, which is not shown. It is sent to the collection container.

  A specific configuration of the upper shell separating means B and the upper shell removing means C shown in FIG. 12 is shown in FIG. The upper shell separating means B includes a pair of upper shell separating injection nozzles (first nozzles) 140 capable of injecting a high-pressure fluid (for example, water) and two pressure feeds having one end connected to each nozzle 140. A hose (not shown) and a pump (not shown) connected to the other end of each pumping hose are provided. The upper shell separating means B includes a measuring device (not shown) similar to that of the first embodiment and a first adjusting mechanism (not shown). The upper shell removing means C includes a set of upper shell suction holders 141 capable of sucking and holding the upper shell 103a, two pressure hose 142 having one end connected to each holder 141, and each pressure hose 142. And a vacuum pump (not shown) connected to the. Two sets of the upper shell separating spray nozzle 140 and the upper shell suction holder 141 each form a pair, one for processing the shell 103 set on one mounting portion 107 of the shell mounting base 104 and the other. The shell 103 set on the other mounting portion 107 of the shell mounting base 104 is processed. That is, two shells 103 set on one shell mounting base 104 and supplied simultaneously can be processed simultaneously.

Each of the upper shell separation injection nozzles (first nozzles) 140 includes a hose connection portion 143 to which a pumping hose is connected, and an injection port 144 formed to be tapered. As in the first embodiment, the size of the shell 103 is measured by the measuring device, the position and size of the non-striated muscle portion of the shell 103 is calculated by the first adjustment mechanism, and the calculated non-striated muscle portion of the shell 103 Based on the position and size, the position of the nozzle 140 and the injection angle are adjusted so as to hit the entire non-striated portion of the shell 103. The measuring device is not necessarily provided in the upper shell separating means B shown in FIG. 16, but is provided in the shell supply part P, the shell detecting part Q ₁ , the opening forming means A, etc., and the size of the shell 103 is determined in advance. It can also be measured. Further, the angle of the injection port 144 can be changed manually by turning the T-shaped handle 146 clockwise or counterclockwise.

  A lower shell of each upper shell suction holder 141 is provided with an upper shell suction portion 147 formed of a flexible material (for example, synthetic resin) so as to have a substantially concave cross section, and the center of the bottom surface of the upper shell suction portion 147 is provided. Has a suction port. Further, the suction port communicates with a space 148 provided above the upper shell suction portion 147, and one end of the pressure hose 142 is connected to the space 148.

  The upper shell separating injection nozzle (first nozzle) 140 and the upper shell suction holder 141 are integrated by an angle 149 and are integrally displaced by the action of the lifting piston 150 and the rotating piston 152. Specifically, the lift piston 150 moves up and down between a standby position indicated by a solid line in FIG. 16 and a work position indicated by a one-dot chain line. Further, the rotating piston 152 rotates from the working position to the upper shell discharging position indicated by a two-dot chain line in the drawing, and also rotates (returns) from the upper shell discharging position to the standby position.

  Next, the operation of the upper shell separating means B and the upper shell removing means C having the above configuration will be described. When the processing in the opening forming means A is completed, the turntable 2 is rotated by a predetermined amount, and the shell mounting table 4 on which the shell 3 having the opening formed thereon is set, the upper shell separating means B and the upper shell removing means. Supply to C. Then, the measuring device measures the size of the shell 103, and the adjusting mechanism calculates the position and size of the non-striated muscle portion of the shell 103 according to the measured size of the shell 103. Next, the rod 151 of the elevating piston 150 contracts, and the upper-shell separating injection nozzle (first nozzle) 140 and the upper-shell suction holder 141 in the standby position are lowered to the working position, and the upper-shell suction is performed. The upper shell suction part 147 of the holder 141 is pressed against the outer surface of the upper shell. Next, the nozzle 140 is moved by the first adjustment mechanism, and based on the calculated position and size of the non-striated muscle portion 105a of the shell 103, the position and the spray angle of the nozzle 140 are changed to the non-strip of the upper shell 103a and the shell 105. It adjusts so that a fluid can be ejected from the adhesion part side with the stripe part 105a. Next, the pump connected to the upper shell separating injection nozzle 140 is activated, and the injection of the high-pressure fluid is started from the injection port 144 of the nozzle 140, and the upper shell inner surface and the shell pillar 105 in close contact therewith from the opening. The high-pressure fluid is sprayed for a predetermined time from the adhering side of the upper shell 103a and the non-muscle portion 105a of the scallop 105. Simultaneously with the fluid injection from the upper shell separating injection nozzle 140, the vacuum pump is operated to adsorb the upper shell 103a to the upper shell suction portion 147. As a result, the non-striated muscle portion is peeled off from the inner surface of the upper shell by the hydraulic pressure, and the inner surface of the upper shell 103a and the scallop 105 are separated from each other and the striated muscle portion of the shell pillar is also peeled off. During this time, the shell 103 is pressed against the shell mounting base 104 by the upper shell suction portion 147 pressed against the upper shell 103a and is adsorbed by the upper shell suction portion 147. There is nothing to do. Thereafter, the rod 153 of the rotating piston 152 extends to move the upper shell separating injection nozzle 140 and the upper shell suction holder 141 to the upper shell discharge position. As a result, the upper shell 103a is separated from the lower shell 103b, sucked and held by the suction holder 141, and carried to the upper shell discharge position. When the upper shell suction holder 141 reaches the upper shell discharge position, the vacuum pump is stopped, and the suction holding of the upper shell 103a is released. As a result, the upper shell 103a falls on the slope 153 installed below the upper shell discharge position, slides on the slope 153, and is sent to a collection container (not shown). Note that the lower shell 103b is always held by suction during these series of processes.

The specific configuration of uronium removal means D ₁ shown in FIG. 12 is shown in FIG. 17 (a). The uro removal means D ₁ includes a suction nozzle 160 that sucks and removes the uro 106 a of the associated portion 106, a transfer hose 162 having one end connected to the nozzle 160, and an attached to the other end of the transfer hose 162.

For the associated receiver tank 168, for example, a tank having an arbitrary size such as a tank having a capacity of several tens of liters can be used, and a discharge port for discharging the accommodated urine can also be provided. Here, the suction nozzle 160 for sucking and removing the urine 106a is in the form of an elongated pipe, and the tip thereof is sharply pointed so that it can be easily inserted into the coating of the uro 106a. The two pairs of suction nozzles 160 and the transfer hose 162 form a pair, one for processing the shell 103 set on one mounting portion 107 of the shell mounting base 104, and the other for the shell mounting base 104. The shellfish 103 set on the other mounting portion 107 is processed. That is, the scale 106a can be removed simultaneously from the two shells 103 set on one shell mounting base 104 and supplied simultaneously. Further, the suction nozzle 160 is integrated by the holder 164, and is lifted and lowered between the standby position and the working position by the action of the lifting piston 165.

  The shape of the suction nozzle 160 is not limited to that shown in FIG. 17A. As shown in FIG. 17B, the suction nozzle 160 has a diameter larger than that of the suction nozzle shown in FIG. A blade 169 may be provided at the periphery. When the suction nozzle 160 is used, the blade 169 is pressed against the coating of the scale 106a to tear and tear the coating, and then the scale 106a in the coating is removed by suction. Also, as shown in FIG. 17 (c), the diameter is made larger than that of the suction nozzle shown in FIG. 17 (a) so that the entire coating of the uro 106a can be covered. You can also. When the suction nozzle 160 is used, the coating of the uro is broken by suction and the uro inside is sucked and removed. Also, as shown in FIG. 17 (d), a breakage tool 185 is provided on the inner side, the tip of the breakage tool 185 protrudes downward from the suction nozzle 160, and the protruding tip is sharply sharpened. You can also When this suction nozzle 160 is put on the coating of the scale 106a, the coating 106 is broken by the tip of the breaker 185, and the scale 106a is sucked and removed. The shape of the suction nozzle 160 is not limited to that described above, and may be any other shape.

Next, the operation of the scale removal means D ₁ having the above configuration will be described. When the processing in the upper shell separating means B and top shell removal means C is completed, supplies rotates the turntable 102 by a predetermined amount, the shell loading platform 104 lower shells 103b is set to the uronium removal means D ₁ . Then, the rod 166 of the elevating piston 165 contracts, the suction nozzle 160 at the standby position is lowered to the working position, and the tip of the suction nozzle 160 is inserted into the coating of the scale 106a. Next, a vacuum pump (not shown) connected to the nozzle 160 via the recovery hose 162 is operated (although the vacuum pump can be operated before or during the lowering of the nozzle 160). As a result, the contents of the scale 106a and the film are sucked and removed by the suction nozzle 160, and the collected scale 106a is sent to the collection container provided integrally with the vacuum pump via the transport hose 162. When the suction removal is completed, the vacuum pump is stopped, and in synchronization with this, the rod 166 of the elevating piston 165 extends to raise (return) the suction nozzle 160 to the standby position.

FIG. 18 shows a specific configuration of the associated part removing means D ₂ shown in FIG. 12. The accompanying part removing means D ₂ is a suction nozzle 161 that sucks and removes the accompanying parts (run 106 b, string 106 c, other heart, scissors, tentacles, etc.) 106 other than uro among the accompanying parts 106, and one end connected to the nozzle 161. The transfer hose 163 and a vacuum pump (not shown) connected to the other end of the transfer hose 163 are provided. Here, the suction nozzle 161 that sucks and removes the accompanying portion 106 other than the uro is composed of a cylindrical tube portion 161a and a wide umbrella-shaped covering portion 161b, and inside the covering portion 161 is a diameter of a scallop. Two claws 161c are formed at a further interval. The two pairs of suction nozzles 161 and the transfer hose 163 form a pair, one of which processes the shell 103 set on one mounting portion 107 of the shell mounting base 104 and the other of the shell mounting base 104. The shellfish 103 set on the other mounting portion 107 is processed. That is, the scale 106a can be removed simultaneously from the two shells 103 set on one shell mounting base 104 and supplied simultaneously. Further, the suction nozzle 161 is rotatably attached to the holder 190, and is moved up and down between the standby position and the working position by the action of the lifting piston 191.

Next, the operation of the associated part removing means D ₂ having the above configuration will be described. When the processing in the upper shell is completed by the uronium removal means D _1, rotates the turntable 102 by a predetermined amount, and supplies the shell loading platform 104 lower shells 103b is set to the associated part removing means D _2. Then, the rod 192 of the elevating piston 191 contracts, the suction nozzle 161 at the standby position is lowered to the working position, and the shell pillar 105 and the accompanying portion 106 in the lower shell 103b are covered with the covering portion 161b of the nozzle 161. Next, the suction nozzle 161 is rotated, and at the same time, the vacuum pump connected to the nozzle 161 via the recovery hose 163 is operated (although the nozzle 161 is rotated before or during the lowering of the nozzle 161 or the vacuum pump is operated). Can also be activated). As a result, the two claws 161c provided on the inner side of the covering portion 161b rotate, and the associated portion 106 except for the uro in the lower shell 103b is scraped by the claws 161c, removed by suction, and collected. 106 is fed into a collection container (not shown) via a transfer hose 163. When the suction removal is completed, the rotation of the suction nozzle 161 and the vacuum pump are stopped, and in synchronization with this, the rod 192 of the elevating piston 191 extends to raise (return) the suction nozzle 161 to the standby position.

  FIG. 19 shows specific configurations of the lower shell separating means E, the scallop collecting means F, and the lower shell discharging means G shown in FIG. The lower shell separating means E includes a set of lower shell separating injection nozzles (second nozzles) 170 similar to the upper shell separating injection nozzles 140 constituting the upper shell separating means B, and one end of these nozzles 170. The pumping hose (not shown) connected and the pump (not shown) connected to the other end of this pumping hose are provided. Of course, the upper shell separation injection nozzle (first nozzle) 140 constituting the upper shell separation means B is installed upward, but the lower shell separation injection nozzle (second nozzle) constituting the lower shell separation means E is used. Nozzle) 170 is installed downward. The lower shell separating means E is also provided with a measuring device and a second adjusting mechanism (not shown) similar to the upper shell separating means B, and is based on the size of the shell 103 measured by the measuring device. On the basis of the position and size of the non-striated muscle portion of the shell 103 calculated in this way, the second adjustment mechanism causes the position of the nozzle 170 and the spray angle to hit the entire attachment portion between the shell pillar 105 and the lower shell 103b of the shell 103. As adjustable. However, the lower shell separating means E may be provided with a numerical value of the size of the shell 103 measured by the measuring device of the upper shell separating means B without providing a measuring device. The scallop recovery means F includes a set of suction nozzles 171, a recovery hose 172 having one end connected to the suction nozzle 171, and a vacuum pump (not shown) connected to the other end of the recovery hose 172. I have. Here, the lower shell separating injection nozzle 170 and the suction nozzle 171 are integrated by a bracket 173, and due to the action of the lifting piston 174, between the standby position indicated by the solid line in FIG. Go up and down. Further, the lower shell discharging means G includes a claw 178 having a protrusion 177. Further, the lower shell discharging means G is rotated from the working position by the rotating piston 179 to the lower shell discharging position indicated by a two-dot chain line in the drawing, and is rotated from the lower shell discharging position to the standby position (returns). ). At that time, the projection 177 of the claws 178 is inserted into the lower part of the lower shell 103b set on the mounting part 107 of the shell mounting base 104, and the lower shell 103b is placed on the slope 181 installed below the lower shell discharging position. Can be dropped. Two pairs of lower shell separating spray nozzle 170, suction nozzle 171, and claws 178 form a pair, one for processing shell 103 set on one mounting portion 107 of shell mounting base 104, and the other for The shell 103 set on the other mounting portion 107 of the shell mounting base 104 is processed. That is, two shells 103 set on one shell mounting base 104 and supplied simultaneously can be processed simultaneously.

Next, operations of the lower shell separating means E, the scallop collecting means F, and the lower shell discharging means G having the above-described configuration will be described. Wherein the processing in the accompanying portion removal means D ₂ is completed, rotate the turntable 102 by a predetermined amount, accompanied unit 106 removes the lower shells 103b of the lower shell separating means E, the adductor muscle recovery means F, lower shells discharging means Supply to G. Then, the rod 175 of the elevating piston 174 contracts to lower the lower shell separating injection nozzle (second nozzle) 170 and the suction nozzle 171 at the standby position to the working position. At the same time, the claw 178 also descends to the side of the lower shell 103b. Next, the nozzle 170 is moved by the second adjustment mechanism, and the position and ejection angle of the nozzle 170 are determined based on the calculated position and size of the non-striated muscle portion 105 a of the shell 103, and the non-striped muscles of the lower shell 103 b and the scallop 105 are determined. It adjusts so that a fluid can be ejected from the adhesion part side with the part 105a. Next, the pump connected to the lower shell separating injection nozzle 170 is activated, and the injection of the high-pressure fluid is started from the injection port of the nozzle 170, so that the inner surface of the lower shell 103b and the shell column 105 in close contact therewith The high pressure fluid is jetted for a predetermined time from the side where the lower shell 103b and the non-muscle portion 105a of the scallop 105 are attached. The vacuum pump connected to the recovery hose 172 is operated for a predetermined time simultaneously with the fluid ejection from the nozzle, and the shell pillar 105 separated from the lower shell 103b is transferred to a recovery container (not shown) via the recovery hose 172. (However, the vacuum pump may be operated before or during the lowering of the suction nozzle 171). As a result, the non-striated muscle portion is peeled off from the inner surface of the lower shell 103b by the hydraulic pressure, and the inner surface of the lower shell 103a and the entire scallop 105 are separated from the inner surface of the lower shell 103a which is also peeled off and closely adhered. Next, the rod 180 of the rotating piston 179 extends, and the claw 178 located on the side of the lower shell 103b is moved to the lower shell discharge position. As a result, the protrusion 177 of the claw 178 is inserted into the lower part of the lower shell 103b, and the lower shell 103b falls on the slope 181 installed below the lower shell discharge position as the claw 178 moves. The lower shell 103b falling on the slope 181 slides on the slope 181 and is sent to a collection container (not shown).

When the processing in the lower shell discharging means G is completed, the turntable 102 resumes rotating, and the empty shell mounting base 104 is transferred to the shell detecting portion Q ₂ shown in FIG. Similar to the shell detection unit Q ₁ , the shell detection unit Q ₂ includes a sensor (not shown), and can detect whether the shell 103 is set on the shell mounting base 104.

  When it is detected that no shell is set on the shell mounting base 104, the turntable 102 resumes rotation, and the shell mounting base 104 that has been emptied is transferred to the shell supply unit P again. The operator can set a new shell 103 on the shell mount 4 that has been carried.

  As described above, in the shell processing apparatus shown in FIG. 12, a series of shell processing steps such as transporting shells by rotating the turntable, shell opening, removal of accompanying parts, recovery of shell pillars, and shell discharge after recovery of shell pillars are automatically performed. Implemented. Moreover, the process by each means is performed simultaneously in parallel, and a plurality of shellfish are processed at the same time. Note that the processing in each means and the rotation timing and amount of rotation of the turntable linked to this processing are all controlled by a control unit not shown.

Here, another example of the scale removing means D ₁ shown in FIGS. 12 and 17 is shown in FIG. The uro removal means shown here includes a suction gun 202, a suction tool 207 attached to the tip of the suction gun 202, and a tank 211 in which an accompanying part sucked by the suction gun 202 through the suction tool 207 is stored. .

  The suction gun 202 includes a cylindrical main body 203, a switch 206 provided on a side surface of the main body 203, and a suction mouse 204 connected to the end of the main body 203. In the suction gun 202, when the switch 206 is pressed, the suction mouse 204 and the suction tool 207 attached to the tip of the mouse 204 become negative pressure, and a suction force is generated inside them. Specifically, when the switch 206 is pressed, the valve in the main body 203 is opened. Then, compressed air supplied from the external compressor 210 through the air hose 209 is introduced into the suction mouth 204, and the introduced compressed air flows into the hose 208 that connects the main body 203 and the tank 211. As a result, the suction mouse 204 and the suction tool 207 are depressurized to a negative pressure state, and a suction force is generated. For example, as shown in FIG. 21 (a), when the switch 206 is pressed with the tip of the suction tool 207 pierced into the coating 222 of the scale 106a, the suction force generated in the suction mouse 204 and in the suction tool 207. As a result, the uro 106 a in the coating 222 is peeled off from the lower shell 103 b, and the peeled uro 106 a is taken into the main body 203 through the suction tool 207. Furthermore, the uro 106 a taken into the main body 203 is transferred through the hose 208 by the flow of compressed air that has flowed into the hose 208, and is carried to the tank 211. When the switch 206 is turned off, the valve is closed, the introduction of compressed air is stopped, and the suction force is lost. In addition to the scale 106a, an accompanying portion other than the scale (run, string, heart, heel, bill, tentacle, etc.) and the scallop 105 can be suctioned by the suction tool 207 shown in FIG.

  The suction tool 207 is made of an elongated metal pipe, and its tip is sharply sharpened so that it can be easily inserted into the coating 222 of the uro 106a.

  The hose 208 that connects the main body 203 of the suction gun 202 and the tank 211 is a rubber hose, but the material and structure of the hose 208 are not particularly limited. However, from the viewpoint of workability, it is desirable that the hose 208 bends freely. In addition to the rubber hose, it is desirable to use a resin hose, a flexible metal pipe or the like as the hose 208. . In the accompanying part removing means shown in FIG. 20, the inside of the hose 208 is not in a vacuum or a reduced pressure state, and therefore the hose 208 does not need to have a pressure resistant structure.

  The hose 208, the main body 203, the suction mouse 204, the suction tool 207, and the tank 211 can be disassembled and cleaned.

12, shown in FIG. 22 a further example of a uronium removal means D ₁ shown in FIG. 17. The basic configuration of the uronium removal means D ₁ shown in FIG. 22 is similar to that shown in FIG 20. The difference is that a vacuum pump 213 is used, a connector 212 is attached to the tip of the hose 208 drawn from the vacuum pump 213, and a suction tool 207 is connected to the tip of the connector 212. Furthermore, a switch 206 is provided in the connector 212, and suction is started or stopped by operating the switch 206. Specifically, when the switch 206 is turned on, the passage in the connector 212 is opened, and the vacuum pump 213 sucks the inside of the hose 208 and the suction tool 207. Then, the inside of the hose 208 and the suction tool 207 are in a negative pressure state or a vacuum state, and a suction force is generated. For example, when the switch 206 is turned on with the tip of the suction tool 207 piercing the coating 222 of the scale 106a, the scale 106a in the coating 222 is peeled from the lower shell 103b, and the peeled scale 106a is removed from the suction tool 207. And is fed into the tank 211 through the hose 208. On the other hand, when the switch 206 is turned off, the passage is closed and the suction force is lost.

  It is desirable that the hose 208 connecting the vacuum pump 213 and the connector 212 bend freely from the viewpoint of workability. Specifically, a hose having the same material and structure as the hose 208 shown in FIG. 20 is suitable. However, in the accompanying part removing means D shown in FIG. 22, since the inside of the hose 108 is in a reduced pressure state or a vacuum state, it is necessary to have a pressure resistant structure or to be made of a material having high pressure resistance.

When this suction tool 207 is used, the coating film 222 is broken by suction, and the uro 106a inside is sucked and removed. Further, if the suction force is increased, the coating film 222 is also removed by suction after the scale 106a is removed by suction. Further, the suction tool 207 covered so as to wrap the coating 222 of the uro 106a is reciprocated several times horizontally, so that part or all of the coating 222 attached to the shell 105 and the lower shell 103b is partially or completely removed from the shell 105 and the lower shell 103b. If it is peeled off, the scale 106 can be removed by suction while being covered with the film 222. Although not shown, a blade similar to the blade 214 shown in FIG. 21B can be provided on the periphery of the lower end of the suction tool 207 shown in FIG. According to the suction tool 207, when this is covered so as to wrap the coating 222 of the scale 106a, a part or all of the coating 222 is cut by the blade, so that it adheres to the scallop 105 and the lower shell 103b. A part or all of the existing coating 222 can be easily peeled off from the scallop 105 and the lower shell 103b.
