Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for removing internal organs including ovaries of fish bodies such as cod.

[0002]

2. Description of the Related Art A typical prior art is, for example, Japanese Examined Patent Publication No. 3-39651 (Japanese Patent Application No. Sho 6-39651) proposed by the present applicant.
2-80685). In this prior art, a fish body whose head has been cut is sandwiched and transported by a transport means, and a single pressing member provided in the middle of the transport path of the fish body is used to press the abdomen of the fish body to collect eggs. Has been done.

[0003]

In such a prior art, since the pressing member is made of a rigid material such as metal, if the conveying speed is increased in order to improve the processing efficiency of removing the internal organs, the internal organs of the fish body will not be affected. A large impact force acts,
There is a problem that internal organs are damaged. In order to solve this problem, it is easily conceivable that the pressing member is made of a flexible and elastic material such as rubber. However, in this case, the fish body conveyed conveys the elastic force to the downstream side in the conveying direction. The pressing member that is bent flexibly returns to the initial position by the restoring force immediately after the fish body passes, and if internal organs such as ovaries are attached to the pressing member at this time, it will be scattered in an undesired direction. The problem arises.

Therefore, an object of the present invention is to surely remove the viscera extruded from the abdominal cavity of the fish body without scattering and without damaging the viscera so as to improve the efficiency of the viscera removal process. The purpose of the present invention is to provide a visceral extraction device.

[0005]

Means for Solving the Problems The present invention is provided with a conveying means for sandwiching a fish body whose head is cut and for conveying it to the downstream side in the conveying direction, and is provided adjacent to one side of the conveying means and is conveyed. In the visceral take-out device for a fish body, which comprises a pressing means for pressing the abdomen of the fish body, the pressing means comprises at least a rigid base, an inner layer made of an elastic material formed on the outer surface of the base, and an inner layer. Is a visceral take-out device for a fish body, wherein a plurality of pressing members formed on the outer surface of and having an outer layer made of an elastic material softer than the inner layer are provided along the transport path.

[0006]

According to the present invention, the pressing member for pressing the abdomen of the fish body conveyed by the conveying means comprises at least a rigid base, an inner layer made of an elastic material, and an elastic material softer than the inner layer. And an outer layer consisting of. Therefore, even if a fish body conveyed at a high conveying speed comes into contact with the pressing member, there is no possibility that the pressing member will be elastically deformed, and therefore the viscera are prevented from being scattered by the restoring force. You can Moreover, since a plurality of such pressing members are provided along the transport path,
Even if a part of the internal organs is left on the fish body by the pressing member arranged on the most upstream side in the conveying direction, it can be reliably taken out by the remaining pressing member, thereby improving the conveying speed of the fish body, It can be taken out quickly without damaging the internal organs and without scattering.

As a result, angular displacement in the direction of the arrow D is prevented while the connecting member 18 is in contact with the blocking piece 22, so that the pressing member 14a stops near the conveyor belts 4a and 4b and contacts the conveyor belt. Is prevented. Further, when the fish body F passes, the first position P1 and the second position P
Since the angular displacement is possible within the range of 2, the abdomen can be pressed regardless of the size of the fish body.

Next, the operation of the internal device 1 will be described with reference to FIGS. The fish body F is introduced from the start end side of the conveyor belts 4a and 4b with the abdomen of the fish body F directed toward the downstream side in the conveyance direction A. The inserted fish body is conveyed while being sandwiched by the sandwiching surfaces 5a and 5b on both sides thereof, and the head is cut by the head cutting rotary blade 10. The fish body F whose head has been cut off in this way is further conveyed, and the lower side portion Fc is supported by the feed belt 11 at a position in the vicinity of the cut portion, whereby the end portion of the fish body F on the cut side is supported. It is supported horizontally without hanging and is conveyed to the vicinity of the pressing member 14a, and the abdomen contacts the receiving surface 14c of the pressing member 14a. At this time, the pressing member 14a is elastically biased in the direction of the arrow D by the spring force of the spring 24, so that the abdomen of the fish body F just abuts the receiving surface 14c.
Retained.

In such a state, the fish body F is fixed to the conveyor belt 4
It is transported toward the downstream side in the transport direction A by a and 4b. Ovary F that is pushed out by contacting the pressing member 14a
The a and Fb are supported by the receiving surface 14c and can be taken out smoothly without being crushed and without the ovaries Fa, Fb and part of the internal organs adhering to the surface of the pressing member 14a. Further, even if an undesirably large force acts on the fish body F, the pressing member 14a is rotatable with respect to the rotating shaft 14b, so that the force acting on the fish body F is relaxed, and the fish body F and the ovaries Fa and Fb are damaged. Can be prevented.

When the fish F passes near the pressing member 14a, the pressing member 14a freely rotates and the pressing member 1a is rotated.
The ovaries Fa and Fb attached to the surface of 4a and part of the internal organs are shaken off, and these ovaries F are attached to the surface of the pressing member 14a.
Since a, Fb and part of the internal organs do not adhere to each other, the internal organs take-out operation of the fish body F that is subsequently conveyed can be smoothly performed.

As another embodiment of the present invention, as indicated by an imaginary line 25, a plurality of protrusions 25 extending in the axial direction of the pressing member 14a are formed at intervals in the circumferential direction, and the pressing member 14a is pressed. The abdomen of the fish body F that is in contact with the member 14a may be forcibly pressed by rotation in the arrow C direction.

Further, a plurality of pressing members 14a are provided adjacent to one side of the conveyor belts 4a and 4b (3 in this embodiment).
Since the ovary and the intestinal tract which cannot be cut off by the pressing member 14a arranged on the most upstream side in the transport direction A are provided, the second and third pressing members 14a.
With this, it is possible to reliably cut off, and even if the transportation speed of the fish body F is improved, it is possible to reliably take out the internal organs including the ovaries Fa and Fb. When such a single pressing member 14a is used, although only 50 fish bodies F were processed at the conveying speed of 10 m / min, the pressing member 14a was
With a book, it is possible to process 100 fish bodies F at a conveying speed of 20 m / min.
It has been confirmed by the present inventor that 150 fish bodies F are processed at a transport speed of 30 m / min. By providing a plurality of pressing members 14a in this manner, the internal organs removal processing efficiency can be significantly improved.

The internal organs including the ovaries in the abdominal cavity are pushed out with a great force by the ridges 38 and supported by the receiving portion 37. From this state, as the fish body F is further transported to the downstream side in the transport direction A, the fish body F separates from the pressing member 30, and the pressing member 30 returns to the initial position by the elastic recovery force. The internal organs on the receiving portion 37 are locked by the ridge 38 with a large frictional force, but the ovaries and intestinal tracts that have not been broken by this are arranged on the downstream side in the transport direction A. It is possible to make a reliable contact with 30. Moreover, since each pressing member 30 is elastically pressed by the spring 32, there is no possibility that an undesirably large force acts on the fish body F.
