DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a scalloping device for scallops, and more particularly to a machine for jetting hot water and cooling water simultaneously or separately to remove the opening of a shell and an upper shell, and to remove only uro and pimp. The present invention relates to a tact-feed scallop removing machine that can supply a freshly-used scallop by performing a series of operations of peeling off a scallop from a side shell.

[0002]

2. Description of the Related Art Stripping raw scallop from scallops is
It is mainly done by hand, and in a harsh working environment where a large amount of cold water is used, there is much damage to the scallop when peeling,
For low work efficiency and low yield, various types of stripping of a scallop by thermal mechanical or a combination thereof have been conventionally proposed.

[0003] For example, Japanese Patent Application Laid-Open No. 50-3899 discloses that a portion corresponding to the scallop of one of the scallop shells is locally heated by a burner, opened from a hinge portion, and the scallop is separated. A featured proposal is disclosed.
However, no specific shell removing device is disclosed. Japanese Patent Application Laid-Open No. 52-13900 discloses a belt-like transport belt having a transport frame for holding a bivalve in an upright state, and a steam provided on a transport path of the transport belt at a position corresponding to a shell of a shell. A proposal has been disclosed in which a uniform and almost intact shell with little damage is obtained by using a steam jetting device that performs heating and adding water such as boiling water. In this case, too, only a separating means by natural fall of shellfish separated by heat is shown. Further, Japanese Patent Application Laid-Open No. 64-39931 discloses a proposal in which a shell is heated outside a bivalve shell by a plasma arc to separate the shell. Also in this case, there is no specific disclosure about the removal of the shell after the opening by heating and the removal of the shell.

[0004] Recently, Japanese Patent Application Laid-Open No. Hei 5-3751 discloses that
In response to the above prior art, the scallop is divided into a stalk portion and other portions of the scallop, and is not uniformly heated over the entire area of the scallop, but is provided with strength, and is provided by a burner from the outside of the shell corresponding to the scallop portion. Forcible shelling means is disclosed in which heating means for heating is provided, and a half-open upper shell is opened and shelled as the transfer means is transferred. The details of the disclosure are discussed below.

In the above invention, as shown in FIG. 13, the original shell supply unit 50, the centering unit 51, the heating unit 52, the opening and upper shell removal unit 53, the urine and string removal unit 54, the scallop separation unit 55, and the A chain conveyor 56 for transferring the scallops, and the conveyor is
The intermittent operation is stopped between 3 and 7 seconds in synchronism with the back and string removing unit 54. 1) The shell supply unit 50 includes a cross member 56a of an endless chain conveyor 56 and a plurality of fixed frames 57 provided on the center axis of each row of the shell array provided on the member. Is a stopper 57a at the rear end in the transfer direction.
The scallop has a slanted cross-sectional shape that rises obliquely and shallowly at the front, so that the hinge of the scallop is abutted against the stopper. 2) The centering portion 51 forms an imaginary center of the array in the width direction of the stopper 57a shown in FIG. 14 so that the shellfish is always located at the center of the plurality of predetermined arrays in the axial direction with respect to the transport direction of the conveyor. A pair of guide plates 58b, 58b tapered in the transfer direction symmetrically with respect to the center line 58a.
And a position adjusting mechanism is constituted by the guide plate. 3) The heating unit 52 uses, for example, a flame generated by a burner, a beam of laser light, infrared light, halogen light, red-heated metal, or high-temperature steam as a heat source. As shown in FIG. 1), the so-called striated portion 17, which is a non-constrictor, forms a so-called scallop, which is weakly exposed to the heat rays. For example, when using a flame such as a burner or heating by a light source, the center of the flame or the center of irradiation is applied to the non-constrictor portion, and the heating is performed so that the flame or irradiation flows from there to the constrictor portion. In addition, the above-mentioned heating stops a conveyor, heats for 3 to 7 seconds in the case of a gas burner, and after heating is completed, cooling water is sprayed on the upper shell during running of the conveyor to be cooled. 4) The opening and the upper shell removing portion 53 are provided with a lower shell holding rail 53a and a V-shaped opening device 5 as shown in FIG.
3b, the shell holding rail 53a was first inserted between the upper and lower shells opened by the heating unit 52 as shown in FIG. 15 (A), and the opening device 53b was opened slightly as the conveyor advanced. The upper shell 19a is removed as the conveyor advances, as shown in FIG. 15 (B). In addition, cooling water is sprayed on the upper part of the pedestal after removing the upper shell when the conveyor is running to cool it. 5) As shown in FIG.
Suction 58 and pressing member 59 of scallop 16
And a compressed air blowing nozzle 60. A suction port 58a having a notch 58b is provided at a lower portion of the vacuum suction 58, and when the internal organs made of the umbilical cord are sucked, the compressed air is sprayed on the uro and the cord from the blast nozzle 60 so as to be easily peeled from the lower shell, and the suction port is provided. 58a is placed so as to cover the center of the lower shell, and is sucked while rotating around the Uroimo while giving eccentric oscillation. At this time, in order to prevent the scallop from being sucked together, the holding member 59 is configured to press the scallop during suction. Further, the vacuum suction 58 is exchanged and used so as to correspond to the inside diameter according to the size of the scallops. In addition, the suction removal of the internal organs is stopped and performed according to the stop time of 3 to 7 seconds of heating time when the opening and the upper shell are removed.

[0006] The above proposal has various problems, and while the form as a processing machine for quickly supplying a large amount of scallop is maintained, the following problems are particularly noted in terms of ensuring stable quality of scallop for raw consumption. There is a point. 1) Regarding the shell supply unit 50, a, the sitting posture of the shell on the fixed frame is not stable left and right and is not held horizontally. Therefore, the irradiation position of the burner in the heating unit is also inaccurate, and it is not necessarily required Collective irradiation is not always possible. b. Since the fixed frame is defined by the stopper 57a so as to define the front and rear position, it is necessary to change the irradiation position of the burner according to the size of the used shellfish, and thus to overheat the so-called scallop portion formed by the constrictor. become. 2) For the centering portion 51, c, a pair of guide plates 58b, 58 inclined in the transfer direction.
Since the inclination angle of b is fixed, it is not perfect as a position adjusting mechanism, and it is good when the minimum distance between the guide plates substantially matches the size of the shell even for shells of the same size. In the case of (1), the effect is hardly used, and the expected effect is not always obtained reliably in the heating section where the predetermined irradiation position is strictly required. 3) For the heating unit 52, d, a heat source other than hot water is used, and in the case of a burner, irradiation is performed for 3 to 7 seconds. However, it is not clear how to manage the flame temperature and the irradiation time. There is a problem in quality control in a configuration in which heating is carried out for 3 to 7 seconds to strongly heat the stalk portion and weakly to the scallop portion. e. Since the lower shell is not cooled, the heat at the time of heating is also accumulated in the lower part of the scallop, which adversely affects the quality of the scallop. 4) Opening and upper shell removal portion 53 are as follows: f, heating of the upper shell causes relaxation of the upper and lower binding forces of the shell, and the upper shell is opened. Mechanical opening by the V-shaped opening device 53b is impossible and damages the shell surrounding area,
Contamination of the scallop by debris becomes a problem. g. There is a problem that a large change is caused in the position of the lower shell due to the excessive opening by the mechanical means, which hinders the work in the subsequent process. In particular, the positional relationship between the position of the suction port and the internal organs becomes poor in the step of separating and suctioning internal organs, making it impossible to completely remove and remove the urine. 5) Regarding the urine and string removing section 54, since the removal of the internal organs consisting of h, uro and string is not reliable only by blowing the compressed air from the outside and vacuuming the upper part, a strong suction force is obtained. It will be necessary and the whole scallop will be sucked or a part of the scallop will be peeled off. Further, when the upper end of the scallop is pressed by the pressing member in order to prevent the scallop from being sucked together, there is a problem that the surface is damaged and the quality of the scallop is deteriorated. i. If there is a pressing member, the back and the string are caught, and the operation of suction removal is not reliable and stable.

6) Conclusion: In order to obtain a raw edible scallop, it is necessary to heat and open the scallop to such an extent that the binding force between the upper and lower shells is relaxed, and it is necessary for the scallop not to lose its daily functions. To that end, scientific management control is necessary to satisfy the two requirements that are in a trade-off relationship, heating and cooling, at the last minute line, but such consideration is not found. That is, for the separation between the upper shell and the upper end of the scallop, the separation between the internal organs (Uro, String) and the lower shell, and the separation between the lower end of the scallop and the lower shell, the separation part has a predetermined temperature. The heating is performed for a predetermined time, and at the same time, appropriate maintenance is required to maintain daily life functions, and it is necessary to perform cooling at the same time or immediately after the heating is completed. That is, after the separation, it is necessary to restore the paralyzed living function by cooling such as spraying cooling water on the shell. No measures have been taken in the opening means to prevent damage to the periphery of the shell contaminating the scallop. Position correction after the upper shell removal process is required, but not done. The peeling of the scallop must be performed from the side of the scallop to suppress damage to the scallop during peeling.

As shown in FIG. 1, the scallop is composed of a constricted muscle portion 16 called a so-called scallop, a non-constricted muscle portion 17 called a so-called stalk, and an internal organ 18 made of uro and string. The present invention relates to a scallops removing machine for peeling off a scallop 16 and a stalk 17 from a shell while maintaining a living function, and using the scallop as a raw food. The pillar 17
Has a strong binding force to the scallop 16, and the opening of the shell, which is a prerequisite for stripping the scallop, is based on the premise that the connecting force of the stalk 17 is loosened while maintaining the living function of the scallop 16.

As shown in FIG. 2, the scallops removing machine according to the present invention comprises a raw shell supplying unit 20, an opening 21, an upper shell removing unit 22, a visceral separation suction unit 23, and a scallop removing unit 24. , A control unit 25, and a tact transfer unit 26. The raw shell supply unit 20 includes a seating stage 1 for position control, and a posture control and size determination stage 2 for posture control and shell size detection. In the seating stage for controlling the position, the original shell 42 is attached to a cylindrical seat 28 made of a short elastic cylinder disposed at a fixed position in a plurality of rows at regular intervals on a cross bar 40 of a conveyor 41 to be described later shown in FIG. The substantially spherical convex portion of the lower shell of the scallop is capable of regulating the position of the left, right, front and rear. As shown in FIG. 4, the attitude control and size determination stage 2 can slide back and forth (directions of arrows D and E) on an axis YY in the conveyor conveyance direction (hereinafter referred to as a vertical direction) of the seat 28. By controlling the posture of the seated hinges 43 of the seated shells so as to be perpendicular to the longitudinal axis Y-Y by means of the cross-section mountain-shaped guides 29, 29 provided at The result of the determination is input to a control unit 25 described later so that the processing time for heating and cooling can be set according to the size of the shell.

And a stage 5 for cooling the scallop. The heating and cooling of the stage 3 and the cooling of the stage 5 form a first heating and cooling means, and the heating in the stage 3 paralyzes and relaxes the binding force between the upper part of the scallop and the upper shell, while maintaining the life function of the lower part of the scallop. It is done as planned. In addition, the cooling of the stage 5 allows the upper part of the scallop paralyzed by heating from the upper shell to quickly return to its daily life function. In addition, the heating uses a hot water jet of 95 ° C. to 80 ° C., and the cooling uses a jet of cooling water, and the jet time is calculated by the control unit 25 based on the size of the shell determined in the stage 2. And a predetermined time 3 set according to the large, medium and small shells
The irradiation time is set to seconds, 2.5 seconds, and 2 seconds, and is appropriately controlled by the control unit. In addition, when the stage 3 is heated and cooled, the original shell whose position is controlled and its attitude is controlled on the seat 28 is pressed from the upper shell by an air pressure by the holding bar 45, and when heated, hot water for heating enters the shell and is heated. To avoid direct thermal damage to the scallop. The pressing means uses a U-shaped holding bar 45 shown in FIG. 5 so that heating with hot water from above can be performed without impeding the injection to the central portion of the upper shell 42. The opening means of the stage 4 is such that the first heating and cooling means of the stage 3 completely opens the upper and lower shells in which the binding force generated between the upper end of the shell and the upper shell is in a flaccid paralysis state. is there.

The upper shell removing section 22 comprises an opening determining stage 6 for detecting an unopened shell by the opening determining means, and an upper shell removing stage 7 by means of the shell removing means comprising an opening inserting member. The opening determination means is configured to detect an apparent change from an unseen opening state caused by the opening of the upper shell with a sensor. For example, as shown in FIG. 7, as can be seen from the reflection state of the sensor output of the sensor 46 provided above the open end of the upper shell, FIG.
In the case of (1), the reflected light of the sensor output of the sensor 46 is input to the sensor light receiving unit, and in the case of FIG.
With this, it is possible to determine the unopened state and the open state. During the transition from the stage 6 to the stage 7, the unopened shell is discharged to the receiving tray 27a so as not to hinder the subsequent steps. Sea shell removal means,
