When the parallel knives 41a and 41b are inserted, the cutting edge is inserted without touching the vertebral body and damaged, and the step 41c reaches the vertebral body part. It is designed to be peeled off.
In addition, since the tip of the blade tip is formed in a thin plate shape having a round body, the ribs of the abdomen and the meat part can be easily peeled without biting into the bone and meat.
[0033]
Since the structure and function of the ventral guide unit 30 are as described above, the description thereof is omitted.
With the above-described configuration, when three-sheet wholesale is performed, the unit body composed of the wholesale unit 40 and the abdominal guide unit 30 is raised in synchronization with the traveling speed of the ascending conveyance path 18a by an elevator mechanism (not shown). During the ascent, the parallel knives 41a and 41b and the dorsal side rollers 42a and 42b are advanced in the direction of the arrow G via the forward / reverse mechanism 43, and the step 41c for pressing and avoiding the parallel knives reaches the substantially vertebral body position. The abdominal guide 31 and the abdominal side rollers 32a and 32b are advanced in the direction of the arrow H by the slide shifter 33 until the abdominal guide 31 substantially contacts the vertebral body.
[0034]
Then, at the end of the insertion pressing by the knife or the various guides, the ascent is stopped to prevent the back side rollers 42 a and 42 b and the abdominal side rollers 32 a and 32 b from shaking the work left and right and the vertebral body center by the abdominal guide 31. In order to prevent the deviation, the workpiece 10 can be lifted up to three parts by being cut down to the lower part of the workpiece by the parallel knives 41a and 41b.
At the end of the devaluation, the unit body and the old positions of the knife and guides are returned.
[0035]
The kama-cut portion 15 is provided in the horizontal conveyance path 18b, and only fillet is cut by a rotating round blade composed of a saw blade-like single blade shown in FIG. 7B. In addition, the shape of the said saw blade uses what is shown, for example in the K section enlarged view of a figure.
[0036]
【The invention's effect】
Since the present invention has the above-described configuration, the head is clamped in three with the head clamped, and only the fillet is discharged at the kama-cut portion. The head and bones can be discharged together.
Compared to a conventional three-sheet wholesaler that uses only a round blade, the dorsal side uses a round blade to cut the thickness of the nerve spine with two round blades, and the ventral side uses a parallel knife shaped like a knife. Therefore, it is possible to wholesale three sheets with a high yield just by leaving one thin skin on the remaining bone.
In addition, since a series of processing is possible, processing up to fin removal, stomach splitting, built-in removal, and egg collection becomes possible.
