As the inclination angle γ formed between the advancing/retreating direction of the separating cutting blade 61 and the transport direction A, the blade tip of the separating cutting blade 61 is an inner surface of the lower shell Sb when the scallop Sc is separated from the lower shell Sb. The angle may reach 10 to 45 degrees. The size of the separating cutting blade 61 in the width direction orthogonal to the advancing/retreating direction is smaller than the distance between the pair of pressing bodies 34a. The separating blade 61 is made of metal such as stainless steel and has a thickness of about 0.1 to 5.0 mm. The cutting blade 61 for separation may have a curved shape whose tip portion is downwardly convex. In this case, the curved surface shape may be approximated to the cross-sectional shape passing through the center of the inner surface of the lower shell Sb, that is, the axis of the scallop Sc. Further, the separating blade 61 may be flexible so that it can be deformed by an external force in both the length direction and the width direction orthogonal to the length direction.

The separation unit 16 is provided with a holding means 63 for holding the state where the scallop Sc separated from the lower shell Sb by the separation cutting blade 61 is placed on the separation cutting blade 61. As shown in FIG. 2, the holding means 63 of the present embodiment is configured by attaching a holding plate 67 to the outer surface of the rear wall 41a of the upper base 41 via a hinge 65. The holding plate 67 is swingably supported about the axis of the pin 65a of the hinge 65, and the front end portion of the holding plate 67 shown on the right side in FIG. 2 is vertically displaceable. Further, the holding plate 67 has a base end portion shown on the left side in FIG. 2 in contact with the rear wall 41a of the upper base body 41, and the maximum opening angle of the hinge 65 that can be opened and closed is restricted. As a result, the holding plate 67 is normally arranged so as to extend above the separating blade 61 in a substantially parallel manner. Further, at the tip of the holding plate 67, when the separation cutting blade 61 separates the scallop Sc from the lower shell Sb, the scallop Sc moves in the traveling direction of the separation cutting blade 61 and gets over the lower shell Sb. A first movement preventing portion 68 for preventing the scallop Sc from moving so as not to fall off is provided. Moreover, when the scallop Sc is separated from the lower shell Sb by the cutting blade 61 for separation on the base end side of the first movement prevention portion 68 of the holding plate 67, the scallop Sc moves with respect to the traveling direction of the cutting blade 61 for separation. A second movement preventing portion 69 is provided for preventing the scallop Sc from moving so as to move in a direction orthogonal to the lower shell Sb so as not to fall over the lower shell Sb. The second movement preventing portions 69 are arranged at both ends in the width direction orthogonal to the length direction of the holding plate 67. Further, the second movement preventing portion 69 is provided so as to incline obliquely outward and downward from the widthwise end portion of the holding plate 67.

Next, the operation of the entire bivalve processing system of the present embodiment having the above-described configuration will be described.

According to the bivalve processing system 1 of the present embodiment, if the scallop S is placed in the shell mounting hole 14aa of the shell mounting portion 14a of the raw shell mounting plate 14 at the supply position SP, the transport device 2 The scallop S is intermittently conveyed by means of the scallop positioning device 3 to position the scallop S, and the heating device 4 connects the scallop Sc to the portion of the surface of the upper shell Sa corresponding to the joint with the scallop Sc used for raw eating. Opening and shelling of the scallop S that holds the raw state and weakens the binding force with the upper shell Sa of the scallop Sc to forcefully open the upper shell Sa by the forced opening device 5 so as to separate the upper shell Sa from the scallop Sc. Separation of the upper shell Sa by the separating device 6, separation of the non-edible portion by the non-edible portion separating device 7, and separation by cutting of the scallop Sc remaining in the lower shell Sb by the shell edible portion separating device 10 can be performed in this order. Therefore, the scallop Sc of the scallop S can be efficiently taken out from the shell in a raw state.

Here, the operation of the shell edible portion separating apparatus 10 which is a part of the bivalve processing system 1 of the present embodiment will be described in detail.

The separating operation of the scallop Sc by the shell edible portion separating apparatus 10 of this embodiment is started when the raw shell plate 14 stops at the edible portion separating position P6. Then, when the raw shell plate 14 is stopped at the edible portion separating position P6, the separating unit 16 is lowered together with the support frame 32 by the driving force from the driving source (not shown). Immediately before the separation unit 16 reaches the descending end, the lower surface of the pressing body 34a contacts the diagonally upper right portion and the diagonally lower left portion of FIG. 4 in the opening end portion of the lower shell Sb. Then, when the separation unit 16 reaches the lower end, the pressing body 34a presses the lower shell Sb at two places by the urging force of the compression coil spring 38 and temporarily fixes it in the shell mounting hole 14aa of the raw shell mounting plate 14. At this time, since the pressing body 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 placing plate 14 to the opening end of the lower shell Sb is different, That is, the lower shell Sb can be fixed with a constant load regardless of the size of the scallop S. Immediately before the separation unit 16 reaches the lower end, the lower surface of the first movement preventing portion 68 provided at the tip of the holding plate 67 contacts the upper end of the stopper 14ab. When the separation unit 16 reaches the lower end, the holding plate 67 moves counterclockwise in FIG. 2 about the axis of the pin 65a of the hinge 65 so that the tip of the holding plate 67 moves upward. That is, the hinge 65 operates in the closing direction. Further, when the separation unit 16 reaches the lower end, the separation cutting blade 61 is positioned diagonally above and above the lower shell Sb temporarily fixed by the temporary fixing means 20, and the cutting edge of the tip thereof is The inner surface of the temporarily fixed lower shell Sb can be advanced toward the front of the joint with the scallop Sc. Further, the holding plate 67 is located above the scallop Sc. The state where the separation unit 16 reaches the lower end is shown in FIGS. 7 and 8. Note that in FIGS. 7 and 8, only main parts are denoted by reference numerals, and other reference numerals are omitted. In addition, when there are a plurality of identical objects, only some of them are denoted by reference numerals.

Then, when the separation unit 16 reaches the lower end, the reciprocating cylinder 53 is driven and the output shaft 53a thereof is retracted, so that the separation blade 61 together with the moving shaft 57 is temporarily fixed from diagonally above and below the lower shell Sb. The lower shell Sb advances toward the front of the joint with the scallop Sc of the inner surface. Then, the cutting blade 61 for separation contacts the inner surface of the lower shell Sb while advancing, and then cuts the scallop Sc at the connecting portion with the lower shell Sb, that is, at the base to reach the forward end. At this time, the cutting blade 61 for separation swings around the axis of the moving shaft 57, and the swing base 40 swings around the axis of the swing support shaft 43, so that the blade edge has a lower shell. It moves up and down in accordance with the shape of the inner surface of Sb and moves in a direction orthogonal to the direction of travel. As a result, the blade edge moves smoothly along the inner surface of the lower shell Sb, so that the scallop Sc can be reliably and easily cut at its root without damaging the inner surface of the lower shell Sb. Then, the scallop Sc cut from the inner surface of the lower shell Sb is held in a state of being placed on the upper surface of the separation cutting blade 61. At this time, the holding plate 67 located above the separating blade 61 can prevent the scallop Sc from falling off the upper surface of the separating blade 61. 9 and 10 show the separated state of the scallop Sc, which is obtained by cutting the scallop Sc from the inner surface of the lower shell Sb. Note that in FIGS. 9 and 10, only main parts are denoted by reference numerals, and other reference numerals are omitted. In addition, when there are a plurality of identical objects, only some of them are denoted by reference numerals.

Then, when the cutting of the scallop Sc by the cutting blade 61 for separation is completed, the separation unit 16 moves up. At this time, the holding plate 67 holds the scallop Sc on the upper surface of the separating cutting blade 61. Then, when the separation unit 16 reaches the rising end, the raw shell placing plate 14 moves toward the downstream side in the transport direction and separates from the edible portion separating position P6. By moving the reciprocating cylinder 53 and advancing its output shaft 53a at the same time as the movement of the raw shell mounting plate 14 away from the edible portion separating position P6, or after moving away from the edible portion separating position P6, The cutting blade 61 for separation is returned to the original position. At this time, the scallops Sc placed on the upper surface of the separation cutting blade 61 are discharged by dropping from the separation cutting blade 61. The scallops Sc can be collected by a container or a conveyor (not shown) arranged below the edible portion separating position P6. The discharged state of the scallop Sc is shown in FIGS. 11 and 12. Note that in FIGS. 11 and 12, only main parts are denoted by reference numerals, and other reference numerals are omitted. In addition, when there are a plurality of identical objects, only some of them are denoted by reference numerals.

As described above, according to the shell edible portion separating apparatus 10 of the present embodiment, the lower shell Sb is placed in the shell mounting hole 14aa, the hinge portion thereof faces rearward, and the shell tip portion opposite to the hinge portion faces forward, If the Sc is placed facing upward, the lower shell Sb can be supplied to the edible portion separating position P6. Then, by lowering the separation unit 16 with respect to the lower shell Sb supplied to the edible portion separating position P6, the opening end of the lower shell Sb at the edible portion separating position P6 is pressed from above by the temporary fixing means 20. Can be fixed. Furthermore, by advancing the separating cutting blade 61 toward the inner surface of the lower shell Sb, the scallop Sc can be separated by cutting. Therefore, high performance can be easily achieved.

Further, according to the shell edible portion separating apparatus 10 of the present embodiment, the temporary fixing means 20 is a preset part of the opening end of the lower shell Sb by the preset force of the compression coil spring 38. Can be temporarily fixed by pressing from above, the reciprocating cylinder 53 can reciprocate the cutting blade 61 for separation, and the oscillating base 40 moves the tip of the cutting blade 61 for separation up and down. The tension coil spring 49 can urge the swinging base body 40 so that the tip of the cutting blade 61 for separation always faces downward by a preset force, and the position adjusting screw. 51 can determine the downward movement limit position of the tip of the separating cutting blade 61.

Furthermore, according to the shell edible portion separating apparatus 10 of the present embodiment, the separating cutting blade 61 swings about the axis of the moving shaft 57, and the swinging base 40 moves along the axis of the swinging support shaft 43. By swinging about the center, the cutting edge provided at the tip of the separating blade 61 can be smoothly moved along the inner surface of the lower shell Sb, so that the inner surface of the lower shell Sb is not damaged. The scallop Sc can be reliably cut at the root. Therefore, the scallop Sc can be efficiently separated.

Further, according to the shell edible portion separating apparatus 10 of the present embodiment, since the cutting blade 61 for separation is arranged obliquely above and above the lower shell Sb, the raw shell plate that moves along the transport direction A Interference with 14 can be reliably and easily prevented, and it can be easily moved along the inner surface of the lower shell Sb.

Furthermore, according to the shell edible portion separating apparatus 10 of the present embodiment, the holding means 63 can securely hold the separated shell Sc on the cutting blade 61 for separation.

Furthermore, according to the shell edible portion separating apparatus 10 of the present embodiment, since the raw shellfish is the scallop S, the scallop Sc used for eating the scallop S can be efficiently separated.

Further, according to the shell edible portion separating apparatus 10 of the present embodiment, since the holder 59 is detachably attached to the moving shaft 57, the moving shaft 57 is removed from the swinging base 40 without removing the moving shaft 57. By a simple method of removing the holder 59, the separation cutting blade 61 can be easily replaced.

It should be noted that the present invention is not limited to the above-described embodiment, and various modifications can be made if necessary. For example, the shell edible portion separating device may be used alone. In this case, the table may be a rotary table that can be driven intermittently, and a plurality of shell mounting portions can be radially provided on the upper surface of the rotary table at equal intervals.
