It is attached. As shown in FIG. 11, the swing angle β of the moving shaft 57 is about 20 degrees in the left-right direction about the axis of the moving shaft 57.

The other end side of the moving shaft 57, which is shown diagonally downward to the right in FIG. 7, protrudes to the outside of the connecting plate 44 arranged on the short plate portion 41b of each side plate 41, and the holder 59 is attached to the tip portion thereof. The separation cutting blade 61 is detachably attached via the above.

As shown in FIG. 10, the separation cutting blade 61 is formed of a metal such as stainless steel into a flat plate having a tongue-like thickness of about 3.0 mm, and has a large width in the width direction orthogonal to the advancing / retreating direction. The sill is formed to be smaller than the distance between the pair of pressing members 34a of the scallop shell pressing means 20.

The separation cutting blade 61 may have a curved surface shape whose tip portion bulges downward, and in that case, it is preferable to approximate the inner surface shape of the lower shell Sb to a cross-sectional shape that passes through the axis of the adductor muscle Sc. .. Further, it may be formed of a flexible metal material that is deformed along the inner surface of the lower shell Sb by an external force.

Then, by driving the cylinder 53, the moving shaft 57 connected to the output shaft 53a by the bracket 55 is reciprocated in the axial direction according to the reciprocating movement of the output shaft 53a, and the separating cutting blade 61 is moved forward and backward. It has become so. The inclination angle γ formed by the advancing / retreating direction of the separation cutting blade 61 and the shell transport direction is such that when the shell column Sc is cut from the lower shell Sb and separated, the cutting edge of the separation cutting blade 61 is the lower shell Sb. The angle may be 10-45 degrees as long as it reaches the inner surface, and in this embodiment, it is about 35 degrees.

Further, the separation means 22 is provided with a holding means 63 for holding the scallop Sc separated from the lower shell Sb by the separation cutting blade 61 on the separation cutting blade 61.

As shown in FIG. 7, the holding means 63 has a plate-shaped member 67 attached to the outer surface of the connecting plate 43 of the rocking substrate 40 via a hinge 65, and the plate-shaped member 67 has a hinge.

The maximum angle of the hinge 65 in the expanding direction is regulated by abutting on the plate 43, and the hinge 65 is always arranged substantially parallel to the upper part of the separation cutting blade 61.

Further, at the tip of the plate-shaped member 67, when the scallop Sc is separated from the lower shell Sb by the separation cutting blade 61, the scallop Sc is moved in the traveling direction of the separation cutting blade 61 by the advance of the separation cutting blade 61. A first movement prevention unit 68 is provided to prevent the scallop Sc from moving so as not to move to the lower shell Sb and fall off.

Further, on the base end side of the plate-shaped member 67 from the first movement prevention portion 68, when the scallop Sc is separated from the lower shell Sb by the separation cutting blade 61, the scallop Sc moves in the traveling direction of the separation cutting blade 61. A second movement prevention unit 69 is provided to prevent the scallop Sc from moving so as not to move in a direction orthogonal to the lower shell Sb and fall off.

As shown in FIG. 9, the second movement prevention portion 69 is arranged to face both end portions in the width direction orthogonal to the length direction of the plate-shaped member 67, and is arranged from the end portion in the width direction of the plate-shaped member 67. It is provided so as to incline diagonally outward and downward.

Then, in the scallop separating means 10 of the present embodiment having the above-described configuration, the scallop mounting plate 14 on which the lower shell Sb of the scallop S from which the upper shell Sa and the non-adductor Sd have been removed is placed is the scallop separating portion. When the joint portion with the lower shell Sb of the scallop Sc is heated by the lower shell heating means 151 and the joining force is weakened, the separation unit 16 is lowered together with the support frame 32 to hold the scallop separation portion shell. The lower surface of the pressing member 34a of the means 20 is brought into contact with the diagonally upper right portion and the diagonally lower left portion of the open end portion of the lower shell Sb, and the separation unit 16 is brought to the lower end. When it reaches, the pressing member 34a presses the lower shell Sb downward by the urging force of the compression coil spring 38, and the lower shell Sb is held in the shell mounting hole 14aa of the raw shell mounting plate 14. At this time, since the pressing member 34a presses the lower shell Sb by the urging force of the compression coil spring 38, even if the size in the vertical direction from the upper surface of the raw shell mounting plate 14 to the opening end of the lower shell Sb is different, that is, The lower shell Sb can always be fixed with a constant load regardless of the size of the scallop S.

Further, when the separation unit 16 is lowered, the lower surface of the first movement prevention portion 68 provided at the tip end portion of the plate-shaped member 67 of the separation means 22 is oblique to the left in FIG. 11 of the open end portion of the lower shell Sb. When the separation unit 16 reaches the lower end after being abutted against the upper end of the lower portion, the plate-shaped member 67 is rotated counterclockwise in FIG. 8 about the axis of the pin 65a of the hinge 65, and is shown in FIG. The tip shown on the right side is displaced upward. In FIG. 12, for convenience of explanation, the length direction of the separation unit 16 and the moving direction of the raw shell mounting plate 14 are shown in parallel, so that the lower surface of the first movement prevention unit 68 is the raw shell mounting plate 14. It is in contact with the upper end of the stopper 14ab.

Further, when the separation unit 16 reaches the descending end, as shown in FIGS. 12 and 13, the separation cutting blade 61 of the separation means 22 is diagonally forward and upward of the lower shell Sb held by the adductor muscle separation portion shell pressing means 20. It is arranged so that its cutting edge is advanced toward the joint with the lower shell Sb of the adductor muscle Sc.

Next, when the separation unit 16 reaches the descending end, the cylinder 53 of the separation means 22 is driven, and the output shaft 53a thereof is retracted so that the separation cutting blade 61 and the moving shaft 57 are obliquely forward and upward of the lower shell Sb. Toward the joint with the lower shell Sb of the adductor muscle Sc.

Then, in the separation cutting blade 61, the cutting edge is brought into contact with the inner surface of the lower shell Sb on the way forward, and then the cutting edge is moved forward along the inner surface of the lower shell Sb to cut the adductor muscle Sc at the joint portion, that is, the root. As shown in FIGS. 14 and 15, the cut scallop Sc is held by the separating cutting blade 61 and the plate-shaped member 67. At this time, in the separation cutting blade 61, the moving shaft 57 swings around the axis, and the swing base 40 swings around the shaft of the swing support shaft 45, so that the cutting edge thereof is the lower shell Sb. It is moved up and down with respect to the traveling direction according to the shape of the inner surface of the shell, and is swung in a direction orthogonal to the traveling direction, whereby the cutting edge is smoothly moved along the inner surface of the lower shell Sb, and the lower shell is moved. The adductor muscle Sc is reliably cut at its root without damaging the inner surface of the Sb. Further, when the shell column Sc cut from the lower shell Sb by the separation cutting blade 61 tries to move in the traveling direction of the separation cutting blade 61 by advancing the separation cutting blade 61, the first movement prevention of the plate-shaped member 67 is prevented. The portion 68 prevents the separation cutting blade 61 from moving in the traveling direction, and the second movement prevention portion 69 prevents the separation cutting blade 61 from moving in the direction orthogonal to the traveling direction, from the lower shell Sb. It is prevented from falling off.

Next, when the joint portion of the scallop Sc with the lower shell Sb is cut by the separation cutting blade 61, the separation unit 16 is raised, and when the separation unit 16 reaches the rising end, the transport means 2 is driven to drive the scallop Sc. The raw shell mounting plate 14 on which the lower shell Sb separated from the above is placed is moved to the downstream side of the adductor muscle separation portion P10. At the same time that the original shell mounting plate 14 is moved from the adductor muscle separating portion P10, or after being moved from the adductor muscle separating portion P10, the cylinder 53 is driven and the output shaft 53a is advanced to move the separating cutting blade 61. It is returned to its original position.

Then, when the separation cutting blade 61 is returned to the original position, the scallop Sc held between the separation cutting blade 61 and the plate-shaped member 67 is released and dropped downward, and the scallop separation portion P10. It is either dropped into a storage container (not shown) installed below the transport means 2 and collected, or a conveyor is installed below the transport means 2 and transported to a storage container installed elsewhere for collection.

Next, the operation of the double shell processing apparatus 1 of the present embodiment having the above-described configuration will be described.

According to the double shell processing apparatus 1 of the present embodiment, the scallop S has a large bulge in the shell mounting hole 14aa of the shell mounting portion 14a of the raw shell mounting plate 14 arranged at the supply position SP of the transport means 2. By placing the right shell (lower shell Sb) on the lower side and the left shell (upper shell Sa) with a small bulge on the upper side, and placing the hinge side behind the shell transport direction, the shell is placed. The scallop S is sequentially intermittently transported to the downstream side by the transport means 2, and first, in the positioning portion P1, the shell is placed on the raw shell mounting plate 14 at the center in the width direction orthogonal to the shell transport direction of the scallop S by the raw shell positioning means 3.

Sand and debris of foreign matter adhering to the lower shell Sb are washed away.

Next, in the water removing unit P4, the water removing means 103 blows off the water such as the cleaning liquid adhering to the surfaces of the upper shell Sa and the lower shell Sb to remove the water, and in the upper shell heating unit P5, the adductor muscle Sc is removed by the upper shell heating means 4. After the joint force with the upper shell Sa is weakened by heating the joint with the upper shell Sa to form a gel, the upper shell Sa is opened by the forced opening means 5 in the forced opening P6. The scallop S is separated from the scallop Sc to open the scallop S, and the upper shell Sa separated from the scallop Sc by the upper shell separating means 6 is separated from the lower shell Sb and removed at the upper shell separating portion P7. Then, the upper shell Sa separated from the lower shell Sb and dropped in the upper shell separating portion P7 is collected in a storage container installed below the transport means 2, or is collected by a conveyor in a storage container installed elsewhere. It is transported and collected.

Next, in the non-adductor muscle part peeling portion P8, the joint portion with the lower shell Sb of the non-adductor muscle part Sd such as a scallop or a string other than the adductor muscle sc is peeled off from the lower shell Sb by the non-adductor muscle part separating means 111, and then the non-adductor muscle In the adductor muscle part P9, the non-adductor muscle part Sd is sucked by the non-adductor muscle part separating means 7 and removed from the lower shell Sb. Then, the non-adductor muscle Sd removed from the lower shell Sb by the non-adductor muscle separation means 7 is accumulated in the accumulation means.

Next, in the adductor muscle separation portion P10, the joint portion with the lower shell Sb of the adductor muscle Sc is first heated by the lower shell heating means 151 to form a gel, thereby weakening the joint force with the lower shell Sb of the joint portion. After that, the adductor muscle Sc is separated from the lower shell Sb by the adductor muscle separating means 10. Then, the scallop Sc separated by the scallop separating means 10 is dropped downward after the raw shell mounting plate 14 on which the lower shell Sb from which the scallop Sc has been removed is placed is moved from the scallop separating portion P10, and the transport means 2 It is collected in a storage container installed below, or is transported by a conveyor to a storage container installed elsewhere and collected.

Then, the lower shell Sb of the scallop S from which the upper shell Sa, the non-adductor muscle Sd and the adductor muscle Sc have been removed is discharged from the discharge position OP and collected in a storage container installed below the discharge position OP, or elsewhere. It is transported by a conveyor to the installed storage container and collected.

As described above, according to the double shell processing apparatus 1 of the present embodiment, the adductor muscle Sc and the non-adductor muscle Sd can be efficiently taken out from the scallop S.

Further, according to the non-adductor muscle peeling means 111 of the present invention, the non-adductor muscle Sd can be reliably peeled off from the lower shell Sb held by the non-adductor muscle shell pressing means 112 by the scraper 141. The non-adductor muscle separating means 7 arranged on the downstream side in the shell transport direction of the double-shell processing apparatus 1 in the embodiment can prevent the non-scallop Sd from being torn when separated from the lower shell Sb. , It can be separated quickly, and the efficiency of the separation process of the scallop S can be improved.

Further, according to the adductor muscle separating means 10 of the present invention, the adductor muscle Sc is surely cut from the lower shell Sb held by the adductor muscle separating portion shell holding means 20 by the separating cutting blade 61 of the separating means 22, and the cut adductor muscle is cut. The sc is sandwiched between the separating cutting blade 61 and the holding means 63, and the raw shell mounting plate 14 on which the lower shell Sb from which the scallop Sc is separated is placed is passed from the scallop separating portion P10, and then the separating cutting blade. By releasing the scallop Sc sandwiched between the 61 and the holding means 63, the scallop Sc is dropped onto a container previously installed below the transport means 2 of the scallop separation portion P10 or a conveyor for transporting to a container installed elsewhere. It can be recovered efficiently, and the efficiency of the separation process of the scallop S can be improved.

The present invention is not limited to the above-described embodiment, and various modifications can be made as needed. For example, the scallop separation means may be used alone.
