Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for removing mixed meat from fish, and more particularly to an apparatus for separating ordinary meat from mixed meat of fish and removing the combined meat.

2. Description of the Related Art In fish bodies such as so-called red fish such as sardines, mackerel, and saury, as shown in FIGS. 7 and 8, an oily layer called subcutaneous fat is located inside the epidermis of fish F1. Further, inside the oily layer, there is reddish red meat, which is indicated by reference numeral 2 and is called reddish meat. The mixed meat 2 is more likely to rot than the normal meat 3 and does not taste good when eaten. Therefore, when the meat of fish F1 is ground and used for fishery products such as kamaboko, when mixed meat 2 mixes with normal meat 3, normal meat 3 turns reddish and the quality of the product is improved. Will lower it. Therefore, the removal of such mixed blood meat 2 has been conventionally performed.

There is a thin layer composed of a tissue different from the other portions at the joint between the blood mixture 2 and the normal meat 3 that occupies most of the fish body F1, and the blood mixture 2 and the normal meat 3 are easily separated from each other. I'm running.

FIG. 9 is a cross-sectional view of a blood mixture removal device 5 for a fish body according to the prior art. The blood mixture removal device 5 is provided with a pair of pressing members 6 and 7 formed in a roller shape, and recesses 8 and 9 are formed on the outer peripheral surface of the pressing members 6 and 7 over the entire circumference. . Pressing member
The gears 6, 11 are driven to rotate in opposite directions about the rotation axis of the rotation shafts 13, 14 by the gears 10, 11, 12. The fish body F1 whose head and tail are cut is guided by a guide member (not shown) into the gap 15 formed in a substantially elliptical shape by the recesses 8 and 9, and is rotated by the pressing members 6 and 7. It is sandwiched and pressed. Therefore, as shown in Fig. 10, normal meat 3 of fish body F1
Is pushed toward the outside.

Problems to be Solved by the Invention In the above-mentioned prior art, since the surface of the fish body F1 is slimy, the fish body F1 is sandwiched by the pressing members 6 and 7 when the fish body F1 is sandwiched.
Since 1 is laterally displaced, it cannot be sandwiched at a desired position in the gap 15. The fish body in such a laterally offset state
When F1 is pressed, the mixed meat 2 mixes with the normal meat 3. In addition, there are large and small fish bodies, which depend on the size of the gap 15, and it is necessary to select fish bodies according to the size of the gap 15.

Further, in the above-mentioned prior art, the fish body supplied to the blood mixture removal device is only incised on the abdominal side, and therefore, in order to efficiently push out the normal meat portion from both the abdominal side and the dorsal side. Therefore, it is necessary to make the pressing force of the pressing members 6 and 7 on the fish body F1 extremely large. In such a case, when the fish body F1 is pressed by the pressing members 6 and 7, the blood mixture 2
And, an excessive force acts on the middle bone 16, and the mixed meat 2 and the middle bone 16 are pushed outward together with the normal meat 3. Therefore, it is necessary to adjust the pressing force with which the pressing members 6 and 7 press the fish F1. However, if the pressing force of the pressing members 6 and 7 is adjusted as described above, the configuration becomes complicated and the device becomes large.

Therefore, the object of the present invention is to solve the above-mentioned technical problems, without the fish body laterally escaping or escaping, and regardless of the size of the fish body, reliably hold and press the fish body,
Moreover, it does not complicate the structure, and the mixed meat 2 and the middle bone 16
Press the fish body with a pressing force that does not crush it,
It is an object of the present invention to provide a blood mixture removing apparatus for a fish body capable of surely removing the blood mixture so as to obtain fish meat of improved quality.

Means for Solving the Problems The present invention provides a blood mixture removing apparatus for a fish body, in which the abdomen is cut open in the longitudinal direction and the head is cut to convey the fish body to remove the blood meat. A pair of endless conveyor chains that are vertically arranged in the vertical direction and a sandwiching member that is arranged in parallel to each chain, and is provided in the lower conveyor chain along the transportation path and has a concave shape. The lower holding member having the fish holding surface and the upper conveying chain along the conveying path, which is formed of a material having elasticity and flexibility, is attached to the supporting member and is clamped on the upper side. A member, a pressing member for urging and pressing each of the opposing sandwiching surfaces of the upper and lower sandwiching members in a mutually approaching direction, and a fish body provided upstream of the pressing member with respect to the transport path. Cut the back of An apparatus for removing blood meat from a fish body, which comprises an opening means.

Further, the present invention is characterized in that a hollow portion is provided between the upper holding member provided on the upper transport chain and the support member.

Furthermore, the present invention is characterized in that a space between the upper holding member provided on the upper transport chain and the support member is filled with a flexible material.

Action According to the present invention, when the abdomen is cut open in the longitudinal direction and the fish body whose head is cut is supplied to the starting end side of the transport chain,
It is sandwiched by the sandwiching surfaces of the upper and lower sandwiching members.
At this time, since the fish body is sandwiched between the upper and lower elastic sandwiching members and the concave sandwiching member provided on the lower transport chain, the fish body slips sideways regardless of the size of the fish body. It is sandwiched without being caught. The fish body thus sandwiched between the sandwiching surfaces is transported along the transport path by the traveling drive of the transport chain. During this transportation, the back of the fish is cut open by the cutting means,
Further, the pressing member presses the sandwiching surfaces of the sandwiching member, which are opposed to each other, in the direction of approaching each other. At this time, since the holding member is made of a material having elasticity and flexibility, the holding member can be pressed to the extent that the middle bones of the fish body to be pressed are not crushed, and the holding surface avoids the middle bones and blood mixture. It is deformed, whereby the blood mixture remains between the sandwiching surfaces while being entangled with the midbone. In this way, it is possible to reliably remove blood meat without increasing the size of the device without complicating the structure, and separate fish meat into normal meat and blood meat regardless of the size of the fish body. can do.

Embodiment FIG. 1 is a side view of a blood mixture removal device 20 according to an embodiment of the present invention. The pair of endless transport chains 21a, 21b are wound and stretched around the start end side sprocket wheels 23a, 23b and the end side sprocket wheels 24a, 24b. These sprocket wheels 23a, 23b; 24a, 24b have leveling axes parallel to each other. Sprocket wheel
23a and 23b are driven to rotate about a rotation axis by a drive motor (not shown), which allows the transport chains 21a and 21b to be driven.
Are driven to run at substantially the same speed.

A plurality of holding members 25a, 25b for holding the fish body F1 are arranged in close proximity to each other on the transport chains 21a, 21b. Fish body F
When 1 is supplied from the starting end side, it is sandwiched by the sandwiching members 25a and 25b, and is transported in the transport direction A by the transport chains 21a and 21b.

The blood mixture removal device 20 includes a rotary round blade 26 that is a means for cutting the back of the fish body F1 along the transport path, and a sandwiching member 25a, 25b provided along the transport path of the fish body F1 and facing each other. And pressing members 27a and 27b for urging in the approaching direction. The rotary round blade 26 has a rotation axis line perpendicular to the transport path, and cuts the epidermis on the back of the fish body F1.

FIG. 2 shows a holding member 25 attached to the transport chains 21a and 21b.
FIG. 3 is a side view of a and 25b, and FIG. 3 is a section line III-I of FIG.
It is the sectional view seen from II. The holding member 25a is attached to the transport chain 21a via the support member 31 and the attachment member 32a. A bolt insertion hole 34a through which the bolt 33a is inserted is formed in the support member 31 in the thickness direction thereof. Further, the mounting member 32a is formed with a bolt insertion hole 35a through which the bolt 33a can be inserted while the support member 31 is disposed at the mounting position in the thickness direction thereof. The bolt 33a is inserted into these bolt insertion holes 34a, 35a, and the nut 36a is screwed. In this way, the support member is attached to the mounting member 32a.
The head portion 37a of the bolt 33a is embedded in the support member 31 in a state in which the bolt 31 is attached. The support member 31 and the attachment member 32a are made of metal, for example. A sandwiching member 25a is attached to the support member 31. The holding member 25a includes a spacer 38 fixed to the support member 31 and a pressure contact member 39 fixed to the spacer 38. The spacer 38 is made of rubber or a soft synthetic resin material and has elasticity. A pressure contact member 39 is fixed to the spacer 38. The pressure contact member 39 is made of a material softer than the spacer 38, and has elasticity and flexibility. A space 40 is formed by attaching the pressure contact member 39 to the support member 31 via the spacer 38.

The holding member 25b is made of metal, for example, and is attached to the transport chain 21b via the attachment member 32b. Holding member
A bolt insertion hole 34b through which the bolt 33b is inserted is formed in 25b. Further, the mounting member 32b is formed with a bolt insertion hole 35b into which the bolt 33b is inserted. The bolt 33b is inserted through the bolt insertion holes 34b and 35b, and the nut 36b is screwed thereto, whereby the holding member 25 is fixed to the mounting member 32b. The head portion 37b of the bolt 33b is buried in the holding member 25b,
As a result, a concave groove 41 is formed which faces the holding surface 30b and opens, and extends in the vertical direction in FIG. An embedded body 42 is provided in the groove 41.
Is firmly attached. The embedded body 42 is made of the same material as the press-contact member 39, and has an action of preventing the fish body from skidding. Further, by embedding such an embedded body 42 in the groove 41, it is possible to prevent the fish meat crushed by the device 20 from remaining in the groove 41. It is possible to effectively prevent the propagation of germs and the like generated in such debris and keep the device in a clean state. In addition, cleaning can be performed easily and labor can be reduced.

In addition, when attaching the holding members 25a, 25b to the transport chains 21a, 21b, other configurations may be used instead of the configuration shown in FIG.

Next, a blood mixture removal operation of the blood mixture removal device 20 having the above configuration will be described. The head of the fish F1 is cut in advance, the abdomen is incised to remove the internal organs, and these processes are performed by another processing device. Fish body F1
Is loaded into the device 20 with directivity so that the dorsal-ventral surface becomes substantially horizontal. The fish body F1 carried in is clamped by the clamping surfaces 30a, 30b as shown in FIG. The fish body F1 held by the holding surfaces 30a, 30b has a rotary round blade 26
Thereby, the epidermis 45 on the back is incised. The fish body F1 with the back skin 45 cut open is further conveyed in the conveyance direction A,
As shown in FIG. 5, the pressing members 27a, 27b urge the transport chains 21a, 21 in the direction of approaching each other, and the fish body F1 is compressed by the sandwiching surfaces 30a, 30b. At this time, as described in the section of the prior art, the normal meat portion 46a that occupies most of the fish body F1 is located on the abdominal side in order to easily separate from the normal meat portion 46a and the blood mixture meat portion 46b of the fish body F1. And is pushed outward from the back side. Since the back portion is previously incised by the rotary round blade 26, the normal meat portion 46a can be sufficiently pushed out to the outside even if the pressing force of the sandwiching surfaces 30a and 30b against the fish body F1 is relatively small. Further, since the sandwiching member 25a has elasticity and flexibility, the pressing member 39 is not displaced toward the space 40 side to completely crush the blood mixture part 46b attached to the epidermis in the vicinity of the middle bone. This prevents the mixed blood portion 46b from being pushed out together with the normal meat portion 46a. In this way, it is possible to more effectively separate the normal meat portion 46a and the blood mixture meat portion 46b from each other and take out only the normal meat portion 46a.

The normal meat portion 46a pushed outward from the holding members 25a, 25b in this manner falls from the holding members 25a, 25b as shown in FIG. 6 and is accommodated in the tray 50 installed below the transport chain 21b. To be done. The epidermis 45 that remains sandwiched between the sandwiching members 25a and 25b, the blood mixture portion 46b, and the mid bone 46c are sandwiching surfaces 30a and 30b.
Tray 51 at the end position in the transport direction (see FIG. 1)
Be delivered to. In this way, from fish body F1 blood mixture meat 46b,
By removing the middle bones 46c and the epidermis 45, only the normal meat portion 46a can be taken out.

As another embodiment of the present invention, a scraper or / and a brush for scraping off the normal meat portion 46a may be provided on both sides of the conveying path. Also, the surface 30 of the pressure contact member 39
When unevenness is provided on the surface of the embedded body 42 of the concave groove 41 of the sandwiching member 25b and a, the skid of the fish can be further prevented by the frictional force.

As another embodiment of the present invention, in the above-mentioned embodiment,
Although the fish body F1 is sandwiched and conveyed in the vertical direction by the sandwiching members 25a and 25b, the present invention is not limited to this and may be configured to sandwich in the horizontal direction. It goes without saying that such a configuration is also included in the technical idea of the present invention.

As still another embodiment of the present invention, the space 40 may be filled with a flexible filler made of a material softer than at least the spacer 38, such as sponge or soft rubber. As a result, it is possible to prevent the extruded fish meat and the like from remaining, so that it is possible to suppress the generation of miscellaneous bacteria and to keep the apparatus in a clean state and reduce the labor required for cleaning the apparatus.

Incidentally, for reference, in the above-described embodiment, the transport chains 21a, 21b and the holding members 25a, 25b fixed to the transport chains 21a, 21b are used, but instead of this, a transport belt is used. You can also pinch the fish body F1. However, in this case, for example, when the fish body F1 is relatively large, a large frictional force acts between the fish body F1 and the sandwiching surface of the conveyor belt, which causes the conveyor belt to extend unevenly, As a result, a so-called shingling phenomenon occurs in which the fish body F1 is intermittently transported. However, in the present embodiment, since the sandwiching members 25a, 25b and the transport chains 21a, 21b made of synthetic resin are used, the fish meat is smoothly processed while performing the blood meat removal operation without causing the above-mentioned creaking phenomenon. It can be transported.

EFFECTS OF THE INVENTION As described above, according to the present invention, since the sandwiching surface of the sandwiching member provided on the lower transport chain is formed in a concave shape, the sandwiched fish body is provided on the upper transport chain. The elastic and flexible sandwiching member and the lower sandwiching member are partially fitted into the concave sandwiching surface on the lower side, and the lateral direction with respect to the transportation path of the fish body. The displacement is regulated, and the fish can be reliably held and conveyed. Therefore, it is possible to prevent lateral displacement of the fish body regardless of the size of the fish body, and it is possible to perform the blood meat removal treatment with improved yield. Further, since the back portion cutting means is provided, the normal meat portion can be sufficiently pushed out with a small pressing force. Further, since the chain is used as a means for transporting the fish body, the fish body can be transported smoothly while performing the blood meat removal operation without causing a creaking phenomenon. By these, a fish body with improved quality can be obtained.

Further, according to the present invention, since at least one of the sandwiching members is made of a material having elasticity and flexibility, when the sandwiching member is pressed by the pressing member, a relatively hard portion such as the middle bone of the fish body. It is elastically deformed according to the size of the fish body so as to avoid crushing the middle bone etc., and separates the medium bone and the normal meat part with blood mixture meat and epidermis entangled The normal meat part can be pushed out. As a result, it is possible to reliably remove the mixed meat regardless of the size of the fish body with a simple structure without complicating or enlarging the structure of the device, and to obtain ordinary meat without mixing of the mixed meat. The effect is achieved.
