Description

[Detailed description of the invention] (Field of industrial application) This invention is a device mainly used to remove the bones attached to one piece of fish on both sides after cutting the fish into three pieces.

(Prior Art and Problems) Prior to this application, many mechanized devices for unloading fish into three pieces have been announced and are also commercially available.

Briefly, a pair of left and right gripping type belt conveyors are installed on the receiving member, and the decapitated fish transported by these belt conveyors are separated from the midbone by two almost parallel rotating disc-type blades. It is cut off on both sides and cut into three pieces.

However, in these known mechanized fish, the ribs (also called belly bones) are always still attached to the fish on each side, which is lowered into three pieces, and depending on the type of fish, these ribs may be hard. In some cases, it is better to remove it, and currently it is done manually, and as far as the applicant has researched at the time of this application, there are no mechanized methods on the market.

(Problem to be solved) This idea removes the ribs attached to the left and right pieces of fish by cutting them down into three pieces, without relying on humans.
The purpose is to enable mechanical removal, and the purpose is to provide the market with a device that satisfies this point.

(Means for Solving the Problems) This invention consists of a fish body conveying device and a fish body cutting device, and the fish body conveying device has a horizontal guiding surface on the upper surface of the receiving member fixed to the machine frame. The machine is equipped with two pairs of belt conveyors that are long in the horizontal direction and are held in place by an upright surface. The back surfaces of other endless belts of the same conveyor that are attached to the guide plate surface and that are opposite to this are supported by pressing members that elastically press this endless belt toward the other endless belts. , these raising inner plates and pressing members are arranged symmetrically in a pair of left and right sandwich-type conveyors, and the rotation of the fish meat cutting device is located at a position near the delivery end between each endless belt of the two pairs of sandwich-type conveyors. Disk-shaped bone cutting blades are provided, and each of the bone cutting blades is inserted between the endless belts, and the lower the bone cutting blades, the closer to the endless belt supported by the upright inner plate. The problem has been solved by providing a fish bone resection device that is capable of being vertically or tilted, and is equipped so that its position can be changed.

(Function) In the device of this invention constructed as described above, first, the position and inclination angle of the pair of bone cutting blades of the fish cutting device are adjusted, and the lowest position of the circumference of these blades is adjusted. is the center height of fish A, the upper side is inclined slightly away from the endless belt supported by the guide plate, and the lowest point of the circumference is very close to the inner endless belt (0.5 mm). (approximately 1 mm).

Next, the two pairs of pair-shaped belt conveyors of the fish conveyance device are operated in the same direction and at the same speed.

Then, place one piece of fish A on the receiving member at the carrying end, with its back down, and select the right and left sides of the fish so that the inside is in contact with the endless belt supported by the guide plate, and place it on either of the two belt conveyors. From there, it is sequentially supplied to the conveyance section.

In this way, each piece of fish A is held between a pair of endless belts, and in particular, one side is pressed by the endless belt supported by a guide plate, so that the position is stabilized, and the part with the ribs is at the top. Transported in this position.

Further, the fish meat A is transported to the position of the disc-shaped bone cutting blade of the fish cutting device, and each fish meat A is cut into thin pieces, including the rib portion, and the outer fish meat A portion is cut into thin pieces along with the rib portion. It is carried out from the carrying-out end.

At this time, the tail and the part near the tail of the fish A are short and are transported along the receiving surface of the receiving member.
It passes through the bone cutting blade almost without contacting it.

(Effects) In the device of this invention, which is constructed and operates as described above, a pair of sandwiched belt conveyors are used.
Since the backing up positions are arranged symmetrically with the guide plate and the pressing member, the device of this invention is placed on the left side of the fish A (based on a clean swimming posture) from the input end toward the output end. When viewed from the figure, one piece of fish A on the right side can be fed to the pair of pinching type conveyor, and the fish meat A on the other side can be fed to the pair of pinching type conveyor on the left side, with the bellies positioned on the upper side.

In particular, by positioning the inside of one piece of fish A on the endless belt side that is supported by the guide plate, the endless belt on this side will not move in any direction other than the conveying direction, so it will not move during conveyance. The posture of the fish A is also stabilized, the cutting location by the bone cutting blade is stable, and once the setting is made, the cut state is also almost constant as long as the size of the fish to be supplied is almost the same.

Further, since the receiving members are provided below the two sets of conveyors, even if the fish A is pushed downward due to resistance during bone resection, the fish A falls downward and this posture is not disturbed.

In addition, the pair of bone cutting blades is equipped so that the cutting position and angle of inclination can be changed, so they can be set optimally according to the type and size of the fish.
