[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a scallop processing machine for separating raw edible scallops from scallop shells, and in particular, to externally apply a shell fastening force formed between an inner surface of an upper shell and an end face of a scallop to open a centered shell. The present invention relates to a heating opening device of a scallop processing machine having diagonal upright means for reducing paralysis by irradiating warm water with water, and opening the shell without thermal contamination inside the shell.
[0002]
[Prior art]
Separation of raw scallop from scallops is mainly done manually by female workers, and in long working hours and in harsh working environments with large amounts of water, the working population of female workers from 3K workplaces decreases, The fisheries processing industry is becoming more and more problematic in securing labor force. Therefore, conventionally, there have been proposed various methods of separating and removing a scallop by thermomechanical or a combination thereof.
[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. The proposal has been disclosed. However, no specific opening device is disclosed.
Japanese Patent Application Laid-Open No. 52-13900 discloses a belt-shaped conveyance band having a conveyance frame for holding a bivalve in an upright state, and a steam provided on a conveyance path of the conveyance band 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 for heating and adding water such as boiling water. In this case as well, 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]
Therefore, recently, Japanese Unexamined Patent Publication No. 5-3751 describes that, in response to the above-mentioned prior art, the scallop is divided into a scallop portion and other portions, and the scallop is not uniformly heated over the entire area of the scallop, but is given strength. A forcible shelling means is disclosed in which heating means for heating with a burner is provided from the outside of the shell corresponding to the pillar portion, and the half-opened upper shell is opened and shelled with the transfer of the transfer means. The disclosure is discussed in more detail below, and in particular, the heating opening means associated with the present invention.
In the invention in the above proposal, the opening is made via the raw shell supply means, the centering means, and the heating means.
[0005]
The heating means uses, for example, a flame of a burner, a laser beam, an infrared ray, a beam of halogen light, a red-hot metal, a high-temperature steam, or the like as a heat source, and as shown in FIG. Heat is weakly applied to the constrictor portion 11 forming a so-called scallop, so that heat is applied from the outer side of the shell. For example, when using a flame such as a burner or heating by a light source, the flame center or Heat is applied so that the irradiation center hits, and the flame or irradiation flows from there to the constrictor muscle portion.
In the heating, the conveyor is stopped, and in the case of a gas burner, heating is performed for 3 to 7 seconds, and after heating is completed, cooling water is sprayed and cooled on the upper shell during running of the conveyor.
[0006]
By the way, there are various problems in the above-mentioned proposal, and the form as a method of separating scallops for quickly supplying a large amount of scallops is maintained. is there. In particular, the heating means on the premise of opening the shellfish has the following problems. That is,
a. In the case of a burner, irradiation is to be performed for 3 to 7 seconds using a heat source other than hot water. However, it is not clear how to control the flame temperature and the irradiation time. There is a problem in quality control in the configuration that heats the column strongly and weakly the shell.
b. Since the lower shell is not cooled at the time of heating, the heat at the time of heating is also accumulated at the lower part of the scallop, and there is a problem that the quality of the scallop is adversely affected.
[0007]
In order to solve the above problem, the present inventors heated the upper and lower shells to the extent that they loosened the bonding force, and maintained the daily functions of the separated scallops by making full use of heating and cooling, which are in a trade-off relationship. In order to provide an edible scallop, a proposal has been made in a non-known Japanese Patent Application No. 7-264742, and the configuration of the heating and cooling means for opening the original shell according to the proposal is as follows.
That is, as shown in FIG. 5 (A), in the case of the heating and cooling means of the present invention, the original shell 10 is horizontally supported by the vacuum pad 50, and the hot water source 51 is aimed at the peripheral portion of the shell 11 shown in FIG. And the lower shell 10c is sprayed with cooling water from below by a cooling water source (not shown) to prevent heat accumulation in the lower shell.
However, the heating and cooling means according to this proposal has the following problems.
That is, as shown in FIG. 5 (B), when the upper shell 10a is slightly opened as a result of the lowering of the fastening force to the upper shell due to the irradiation of the hot water, the warm water flows into the lower shell 10c from the opened gap 10d. It causes thermal pollution of the scallop and lowers the quality of raw food. For this reason, as described above, it is necessary to spray cooling water from the lower part on the lower shell, and there is a concern about contamination of sewage into the portion of the scallop and a problem of water saving.
After all, in the former of the prior art, in opening work of the scallops, the paralysis of the bonding force between the scallop and the upper shell is based solely on the viewpoint that heating to the portion of the upper shell corresponding to the scallop is necessary. However, there was no technical consideration for thermal pollution of the scallop at the time of opening, and the use of cooling water to prevent the thermal pollution was established in the latter of the prior art, but the shellfish at the time of opening was still in use. No detailed investigation has been made on the aspect described above, and the technical response to it has been insufficient.
[0008]

BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings. However, unless otherwise specified, the dimensions, shapes, relative positions, and the like of the components described in this embodiment are not intended to limit the scope of the present invention, but are merely illustrative examples. Absent.
1 is a schematic diagram showing a schematic configuration of a heating opening device of a scallop processing machine of the present invention, FIG. 2 is a II-II view of FIG. 1, FIG. 3 is a front view of a concave base of FIG. It is a side view.
[0020]
As shown in FIGS. 1 and 2, the heating opening device of the scallop processing machine of the present invention includes a hot water irradiation unit 30 and an oblique standing means 20.
The diagonally rising means 20 includes a seat 35 for seating the source shell 10, an upper shell pressing part 21, a rising driving part 22, and a pushing part 40.
[0021]
The upright drive unit 22 includes, for example, an actuator 27 such as an air cylinder and a U-shaped drive frame 26 that moves up and down by the actuator 27. A hinge portion 24 parallel to the hinge 10b of the original shell 10 is provided on the lower side of the frame 26 on the opposite side of the hinge so as to form a fulcrum for raising and tilting the upper shell pressing portion 21 without permission.
The upper shell pressing portion 21 is provided with a pressing frame 21a which is fitted to the U-shaped frame 26 via the hinge portion 24 so as to be tiltable, and the stopper 25 regulates the lowermost point of tilting. .
Non-slip members 23, 23 made of a heat-resistant elastic member are provided on both sides of the pressing frame 21a, and the upper frame 10a of the original shell 10 is brought into contact with the upper shell 10a by the weight of the pressing frame 21a via the non-slip member 23. When the shellfish stands up diagonally, it keeps it from slipping downward.
[0022]
The seating pedestal 35 includes an elliptical ring-shaped concave pedestal 37 and a locking member 36 for locking and fixing.
As shown in FIG. 3, the concave base 37 is made of an elliptical ring-shaped elastic member, and the upper concave surface 34 utilizes the characteristic that the surface shape of the lower shell of the scallop is similar to the change in the size of the shell. Then, an inclined contact concave surface 34 similar to the surface shape of the lower shell that comes into contact is formed. Therefore, when the original shell 10 is seated parallel to the pedestal base, the center of the column of the original shell can always be set at a predetermined position.
A plurality of slits 32 are provided in the vicinity of the ring-shaped opening to improve the cushioning property and not to fall off when the shell is small.
Further, the setting direction of the pedestal 35 is made to coincide with the arrow X direction shown in FIG. 3 and the arrow X direction which is the process progress direction shown in FIG. 1, and the hinge 10b of the raw shell 10 is moved backward with respect to the arrow direction. At right angles to the traveling direction.
[0023]
The push-up portion 40 is provided at the center lower portion of the pedestal 35, and an actuator 41 and a rotating roller 42 are connected to the actuator 41, and the rotating direction of the roller 42 is fixed in the arrow X direction shown in FIG. When the roller 42 is raised in the direction of arrow B by the operation of the actuator 41, the roller 42 pushes up the lower part of the shell 10 at the center.
As shown in FIG. 1, the hot water irradiation section 30 is set so that when the original shell 10 is erected obliquely, the hot water irradiation can be performed at the portion corresponding to the scallop of the source shell as indicated by the arrow.
The hot water irradiation used for the hot water irradiation unit 30 uses hot water of 80 to 95 ° C. and corresponds to the large, medium, and small shells determined by the centering device, for example, 3 seconds, 2.5 seconds, and 2 seconds, respectively. The injection time is configured to be variable so as to irradiate.
[0024]
According to the above configuration, in use, first, the upright drive unit 22 is operated to lower the drive frame 26 in the direction of arrow A, and the pressing shell 21a is maintained in a substantially horizontal state via the hinge part 24 and the stopper 25 while the original shell is kept. Lower just above 10.
Next, when the push-up unit 40 is operated to raise the roller 42 in the direction of arrow B, the raw shell 10 is obliquely raised by the non-slip members 23 provided on the pressing frame 21a. At this time, the oblique standing angle of the upper shell of the original shell 10 can be maintained constant regardless of the size of the original shell.
In addition, since the base 35 has an inclined contact concave surface similar to the surface shape of the lower shell of the scallop, as long as the original shell 10 is set horizontally (the base of the base 35 is set horizontally), the scallop of the original shell is set. Can always be set at a predetermined position. Therefore, the center position of the scallop of the raw shell in the obliquely standing state can always be set to a predetermined position, and therefore, the hot water irradiation position can be set with reproducibility, for example, in the portion corresponding to the trajectory, regardless of the size of the raw shell, thereby eliminating poor opening. .
Further, since the hot water is radiated in the obliquely standing state, it is possible to prevent the warm water from entering the shell which is in the half-open state by heating.
[0025]
【The invention's effect】
As described above, according to the present invention, the cooling means is not required than the conventionally required lower shell, and it is not necessary to use extra cooling water as compared with the conventional method, so that a large water saving effect is obtained.
Further, since the configuration is such that hot water is prevented from entering the inside of the shell at the time of hot water irradiation, no thermal contamination is caused on the scallop and freshness of the raw food can be maintained.
Since the tilt angle accuracy and the hot water irradiation position accuracy are uniquely established, it is possible to improve not only the opening yield but also the operating efficiency of the entire system.
