Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is intended to efficiently and reliably separate a scallop from which the internal organs of a bivalve such as a scallop attached to the other shell after the one shell has been removed are removed. The present invention relates to a suitable bivalve scallop separation method and device.

[0002]

2. Description of the Related Art Generally, in order to take out (separate) a edible portion of a raw mollusc composed of bivalves, for example, a scallop of a scallop, from a shell, a thin knife-shaped tool called a shellfish is used. It is performed by expanding two shells by operation and opening the mouth (shell opening), and then separating the scallop from the shell.

However, manually separating the scallop scallops from the shell is inefficient, requires a lot of labor and time, and requires a large number of personnel when a large amount of scallops are landed at one time. There was a problem that the freshness of the scallop would decrease unless it was thrown in and treated quickly.

Therefore, various proposals have heretofore been made in order to efficiently separate the scallops of the scallop from the shells.

As a conventional example of these, for example, Japanese Patent Publication No.
As described in Japanese Patent Publication No. 14014, the tip of the scallop is cut with a cutter or the like to form an opening at the tip of the scallop, and a blade inserted from this opening is slid on the inner surface of one of the shells. There is one in which one shell is separated from the other shell by advancing, and the scallop is left in the other shell, and then the scallop is separated from the shell.

[0006] As another example, for example, Japanese Patent Publication No.
As described in JP-A-36741, one shell of a scallop is heated by a heating means to slightly open the mouth of the scallop, and then one of the heated shells is further opened to remove it.
The scallop is left on the other shell, and then the scallop is separated from the shell after removing the internal organs.

[0007]

However, in any of these publications, separating the scallop from the shell after opening the mouth is done manually, and the scalpel is separated from the shell. There is a problem that the separation still requires a great deal of labor and time.

[0008] Further, when the scallop is separated from the shell using negative pressure by applying the suction means for sucking and removing the internal organs described in Japanese Examined Patent Publication No. 7-36741, the shell is referred to as the trabeculae of the scallop. Since the striated muscle portion that opens and closes the shell is strongly bonded to the shell, there is a problem in that the striated muscle portion and the striated muscle portion of the scallop may be separated and the yield may be reduced.

The present invention has been made in view of these points, and a bivalve mollusc capable of efficiently separating a scallop adhering to the other shell after the one shell is removed from the shell An object of the present invention is to provide a method and apparatus for separating scallops.

[0010]

In order to achieve the above-mentioned object, the characteristic feature of the method for separating bivalve molluscs of the present invention as set forth in claim 1 is the suction capable of supplying a negative pressure. When one of the bivalves is removed by the nozzle, the scallop adhering to the other scallop is aspirated, and at the time of separating the scallop from the scallop with negative pressure, at least one of the joints between the scallop and the scallop is removed. The point is to forcibly cut the part and then suck the scallops.

The feature of the bivalve scallop separating device of the present invention as set forth in claim 2 is that after the negative pressure can be supplied and one shell of the bivalve is removed. It has a suction means for sucking the scallop adhering to the other shell and a cutting means for forcibly cutting at least a part of the joining portion between the shell and the scallop.

Furthermore, the feature of the bivalve scalpel separating device of the present invention as set forth in claim 3 is that the cutting means is at least the truncation muscle of the scallop in at least the joining portion between the scallop and the scallop. It is configured so as to cut the joint portion of the part.

By operating the bivalve scalpel separating device of the present invention in accordance with the bivalve scallop separating method of the present invention, the cutting means causes at least a part of the joint portion between the shell and the scallop. It is possible to cut, and as a result, the suction means can efficiently and automatically suck and separate the scallop from the shell. Furthermore, the cutting means,
Prevents separation of the striated muscle part and the striated muscle part of the scallop when sucking and separating the scallop from the shell by configuring the scallop to open and close the shell of the scallop In addition, the efficiency of suction of the scallop, that is, the efficiency of separating the scallop from the shell can be improved.

At this time, the cutting plate 40 moves up and down in conjunction with the up and down movement of the suction nozzle 9.

Next, the operation of this embodiment having the above-mentioned structure will be described.

According to the bivalve scallop separating device 1 of the present embodiment, the scallops (original molluscs) 2 which have been preliminarily sorted by size by a raw mollusk sorter (not shown) are divided into upper shells and internal organs ( (Not shown) is removed by a well-known method, and the lower shell 2A which is the other shell having the scallops 2a on the inner surface is sequentially supplied to the vicinity of the conveying means 3 by a supply conveyor or the like not shown.

When the bivalve mollusc column separating apparatus 1 of the present embodiment is operated, first, the conveying means 3 is stopped at the disposing position of the separating body 4 in the standby state, for example, for about 10 seconds. The lower shell 2A is driven intermittently as shown in FIG.
While the raw shell mounting plate 6 is stopped, the raw shell mounting plate 6 is mounted so as to be supported from below by the shell mounting holes 7 formed in the raw shell mounting plate 6 by a human or a robot. At this time, the hinge portion 2B of the lower shell 2A placed in each shell placing hole 7 is attached to the stopper 8
(Fig. 4). This hinge part 2B
By contacting the stopper 8 with the stopper 8, the unstretched muscle portion 2aa of the scallop 2a can be positioned on the cutting plate 40 side.

Next, the raw shell plate 6 on which the lower shell 2A is placed is transferred by the transfer means 3 in the shell transfer direction indicated by the arrow A in FIG.
Stops, that is, at the position where the scallop 2a attached to the inner surface of the lower shell 2A faces the suction hole 10 of the suction nozzle 9.

In the standby state, the separating main body 4 is
As shown in FIG. 3, the output shaft 21 a of the lower frame drive cylinder 21 is located at the retracted (contracted) retracted end (upper), and the output shaft 21 a of the lower frame drive cylinder 21 causes each part of the separation body 4 to move. It is located at the rising end farthest from the raw shell mounting plate 6. Further, the output shaft 46 a of the upper frame drive cylinder 46 is located at the forward end (upper) that is advanced (extended), and the upper frame drive cylinder 46 is
With the output shaft 46a, the tip of the suction means 9, that is, the suction hole 10 of the suction nozzle 9 is located above the shell holder 29 and is located at the highest end farthest from the shell mounting plate 6.

When the raw shell mounting plate 6 stops at the position where the separating main body 4 is disposed, the lower frame drive cylinder 21 is driven at a predetermined timing, and the output shaft 21a of the lower frame drive cylinder 21 extends and advances. The lower frame 19 as shown in FIG.

When the output shaft 21a of the lower frame drive cylinder 21 reaches the forward end, that is, the separating body 4 reaches the lowering end, the shell presser 29 is a compression coil mounted on the outer peripheral surface of the lower part of the sliding rod 26. The urging force of the spring 31 presses the edge of the lower shell 2A, and as a result, the lower shell 2A is clamped and fixed between the shell pressing 29 and the raw shell mounting plate 6 by the urging force of the compression coil spring 31. At this time, the shell presser 29 uses the biasing force of the compression coil spring 31 to move the lower shell 2A.
Therefore, it is possible to reliably prevent the lower shell 2A from being damaged by the excessive contact force applied to the lower shell 2A.

That is, in the lower frame drive cylinder 21 of this embodiment, the separation body 4 is moved closer to the lower shell 2A, and when the output shaft 21a of the lower frame drive cylinder 21 reaches the forward end, It has a function of fixing the lower shell 2A by the retainer 29 and the raw shell mounting plate 6.

Next, when the output shaft 21a of the lower frame drive cylinder 21 reaches the forward end, a sensor (not shown) detects that the output shaft 21a of the lower frame drive cylinder 21 reaches the forward end. On the basis of,
The upper frame drive cylinder 46 is driven, the output shaft 46a of the upper frame drive cylinder 46 contracts and retracts, and the upper frame 42 is lowered downward in FIG. The lowering of the upper frame 42 lowers the suction nozzle 9 as a suction means via the plate 15.

The bracket 32 descends in conjunction with the descending of the suction nozzle 9, the descending of the bracket 32 lowers the cutting plate 40, and the leading edge of the cutting plate 40 is centered along the inner surface of the lower shell 2A. Moving in the direction, a part of the joint between the lower shell 2A and the scallop 2a, that is, the scallop 2
A starts to cut with the lower shell 2A of the striated muscle portion 2aa called a trabecula which is most strongly joined to the lower shell 2A.

Further, the lower surface of the bracket 32, which is interlocked with the suction nozzle 9 before the output shaft 46a of the upper frame drive cylinder 46 reaches the retracted end, that is, before the upper frame 42 reaches the lowered end, holds the shell 29 at the bottom. The upper end surface of the positioning plate 39 disposed in the
Is stopped at the position where it comes into contact with the shell presser 29, and the cutting operation of the joining portion between the lower shell 2A and the scallop 2a by the tip edge of the cutting plate 40 is completed. That is, the cutting site can be controlled by the stroke of the cutting plate 40. In the present embodiment, at least the striationless portion 2a.
It is configured so that a can be cut.

Furthermore, the upper frame drive cylinder 46
When the output shaft 46a of the suction nozzle 9 further lowers, the upper surface of the bracket 32 and the lower surface of the flange 12 of the suction nozzle 9 come into contact with each other, the upper frame 42 and the plate 15 start to separate from each other, and the suction nozzle 9 stops descending. The suction hole 10 of the nozzle 9 loosely fits the scallop 2a, that is, surrounds the upper portion of the scallop 2a like a lid without contacting the lower shell 2A. FIG. 7 shows a cut state in which a part of the joint portion of the scallop 2a is cut by the cutting plate 40.

Next, when the output shaft 46a of the upper frame drive cylinder 46 reaches the retracted end, that is, when the upper frame 42 reaches the lowered end, the output shaft 46a of the upper frame drive cylinder 46 reaches the retracted end by a sensor (not shown). Is detected and based on this detection signal, the scallop transfer hose 1
Negative pressure is supplied to the inside of the suction nozzle 9 via 6. Then, in the suction nozzle 9, the air located below the suction hole 10 at the tip is sucked into the suction nozzle 9 through the suction hole 10, and as a result, the scallop 2a is separated from the lower shell 2A and separated. The scallop 2a passes through the suction hole 13 and is sucked into the suction nozzle 9.

That is, the cutting plate 40 as the cutting means.
The striped muscle portion 2 that is hard to peel off from at least the lower shell 2A by
The aa is forcibly cut from the lower shell 2A, and the scallop 2a is separated (sucked and removed) with a negative pressure by the suction nozzle 9 serving as a suction means.
It is possible to surely prevent the inconvenience that the striated muscle portion 2ab and the striated muscle portion 2ab are separated, and to efficiently and reliably separate the scallop 2a from the lower shell 2A.

Further, the scallop 2a sucked into the suction nozzle 9 passes through the scallop transfer hose 16 and is stored in the scallop storage tank 17.

Then, when the separation of the scallop 2a is completed, the supply of the negative pressure to the scallop transfer hose 16 is stopped, and the upper frame drive cylinder 46 and the lower frame drive cylinder 2
The separation body 4 is returned to the standby state by sequentially performing the reverse operation of 1. Then, when the separation main body 4 returns to the standby state, the transfer means 3 is driven, and then the oyster shell mounting plate 6 on which the lower shell 2A for separating the scallops 2a is mounted from the separation main body 4 in the standby state. The raw shellfish mounting plate 6 having the lower shell 2A, which is transported to the arrangement position and in which the scallops 2a have been separated, is
Is conveyed so as to be separated from.

Therefore, according to the bivalve scalpel separating device 1 of the present embodiment, the cutting plate 40 serving as a cutting means.
Can cut at least a part of the joint portion between the lower shell 2A and the scallop 2a, and as a result, the suction nozzle 9 as the suction means can efficiently move the scallop 2a from the lower shell 2A, and
It is possible to surely and easily separate (suck and remove). That is, a large amount of scallops 2 can be processed in a short time without labor. Furthermore, the cutting plate 40, which is a cutting means, is configured to cut a joint portion between the lower shell 2A and the striated muscle portion 2aa of the scallop 2a, so that when the scallop 2a is sucked and separated from the lower shell 2A, While reliably preventing separation of the striated muscle portion 2aa and the striated muscle portion 2ab of the scallop 2a, the suction efficiency of the scallop 2a, that is,
The efficiency of separation from the lower shell 2A of the scallop 2a can be improved.

If a negative pressure is constantly supplied to the scallop transfer hose 16 when the apparatus is driven, a mechanism for selectively supplying the negative pressure and atmospheric pressure to the scallop transfer hose 16 and its supply timing are controlled. Since it is not necessary to do so, the device can be simplified.

Further, the present invention is not limited to the above-mentioned embodiment, but can be modified as necessary.
