The second fish body fixing support device 6 has the same structure as the fish body fixing support device 2, but is provided in the second processing area B so that the fish body P faces the bone holding body moving device (bone extraction device) 5. They differ in that they are fixedly supported in position.
[0010]
The separating body moving device (bone separating device) 3 is located in the first processing area A, and refers to a pair of upper and lower separating bodies 31 and a pair of upper and lower separating bodies on a fish body whose head has been cut off, with reference to FIG. And a drive mechanism 32 for moving to insert and withdraw from the head side. In the embodiment of the separating member moving device (bone separating device) 3 shown in FIG. 5, the movement of the separating member 31 is controlled by the electrically driven gear 33, but the electromagnetic driving and the hydraulic driving may be used. Of course.
In the embodiment, the movement of the pair of separators 31 can be individually controlled by using the motor 34 as a pulse drive motor controlled by a microcomputer.
[0011]
FIGS. 6, 7, and 8 show an embodiment of the separator 31. In the separator 31A of the embodiment of FIG. 7, a metal plate-shaped inner core 35 and the plate-shaped inner core 35 are surrounded. The outer layer 36 is made of a soft synthetic resin as described above. However, it is a matter of course that a metal plate product made of stainless steel or aluminum may be used.
[0012]
In the separator 31B of the embodiment shown in FIG. 8, a bone groove 37 is formed at the center in the width direction, a projection 37a is formed at the outside, a projection 38 is formed at the tip, and a projection 38 is formed. At the tip, a pair of guiding bone grooves 39 in the inclined direction continuous to the bone grooves 37 was added.
In the separator 31C of the embodiment of FIG. 9, the guide bone groove 39 is one on only one side.
[0013]
The rotary blade device 4 is located between the first processing area A and the second processing area B, and has a vertical rotary blade 41 and a motor 42 as main elements with reference to FIG. The tail of the fish being transferred from the area to the second processed area is cut off.
[0014]

[0015]
FIG. 11 shows a bone holding body 51 provided in the bone holding body moving device 5 described above, which has a shape similar to the separation body 31, except that a claw 54 for holding the bone is formed at the tip, and an electromagnet 53. Is different.
[0016]
Next, a method for producing a spine-removed fish body (boneless fish body) will be described.
[0017]
From the fish to be processed, the head is cut off and the internal organs are removed, and after the pretreatment step, the fish body P is prepared. The spine (bone aggregate) Q is present in the fish P, but the present invention is to remove the spine (bone aggregate) Q from the fish P.
[0018]
Referring to FIG. 12, the spine (bone aggregate) Q of the fish P is formed of a main bone q1, a spine q2, an abdomen q3, and a child bone q4.
[0019]
The fish P is supplied to the fish tray 12 on the endless chain 11, 11 at the start end of the intermittent fish transport device 1, and is transferred toward the first processed area A.
[0020]
After the endless chain 11, 11 is intermittently stopped in a state where the fish P is located in the first processed area A, the fish fixed support device 2 fixedly supports the fish P at a predetermined position facing the separated body moving device 3. .
[0021]
In the first processed area A, as shown in FIG. 13, the separating body moving device (bone separating device) 3 inserts a pair of upper and lower separating bodies 31 into the fish body P from which the head has been removed from the head side and alternately. Moving.
(1) Waiting for movement, (2) Approaching the ends of a pair of upper and lower separators 31 to the edge q of the spine (bone aggregate) Q, (3) Advance only the lower separator 31, (4) Only the upper separator 31 is advanced [the pair of separators 31 are advanced to the advanced position], (5) only the lower separator 31 is pulled out, and only the upper separator 31 is pulled out, and then (1) Return to the standby position.
The movement control of the pair of upper and lower separators 31 can be performed by microcomputer control of a motor (pulse drive motor) 34 for the gear 33.
[0022]
As shown in FIG. 14, a pair of upper and lower separators 31 may be inserted and withdrawn simultaneously. In the middle of the movement, the movement of the spine (bone aggregate) Q and the fish meat can be promoted by programming the shock movement and the fine vertical vibration in the front and rear directions of the movement.
[0023]
In the separation body 31B of the embodiment of FIG. 8, the ribs q4 of the spine (bone aggregate) Q are pushed down by the projections 38 and enter the bone grooves 37, thereby preventing the ribs q4 from being mixed into the fish meat. Is done. Further, as shown in FIG. 15, when the abdomen q3 of the spine (bone aggregate) Q is inserted with the abdomen q3 on the separating body 31, it is guided by the guiding bone groove 39 and rides on the projection 38. Since it does not cross, it enters below the front end 37a of the projection 38, so that the abdomen q3 is prevented from entering the fish meat.
[0024]
After the above-described bone separation operation in the first processing area A, the fish fixing support device 2 is set in a standby state, and the intermittent fish transport device 1 is moved toward the second processing area B.
The rotary blade device 4 cuts the tail of the fish being transferred from the first processing area A to the second processing area B.
[0025]
In the state transferred to the second processed area B, the second fish fixed support device 6 moves the fish P to a predetermined position facing the bone holding body moving device (bone extraction device) 5 similarly to the fish fixed support device 2. Fix and support.
[0026]
Referring to FIG. 16, the bone holder moving device (bone extraction device) 5 moves the pair of upper and lower bone holders 51 to the standby position [magnetic repulsion] (1), approach (2), and the epiphysis by magnetic attraction. The portion is changed to {3} and extraction {4}, and the spine (bone aggregate) Q is extracted from the fish P.
[0027]
Thus, a spine-removed fish (boneless fish) is completed. After the second fish fixed support device 6 is in a standby state, the intermittent fish transport device 1 is driven.
[0028]
At the end of the intermittent transfer device 1, the process is completed by removing the spine-removed fish (boneless fish) from the fish tray 12 on the endless chain 11, 11.
[0029]
In the above embodiment, the first processing area and the second processing area are operated at the same timing, and three fish bodies P are simultaneously processed. Note that the apparatus can be simplified by processing one fish P at the same time. On the other hand, it is possible to increase the work efficiency by increasing the number of work pieces from three.
[0030]
