A device comprising a standing means and a pair of clamping members provided near the downstream side of the standing means in the conveying direction, the standing means comprising a pair of standing rollers that can swing left and right along the conveying direction. , the pair of erecting rollers are elastically biased toward each other so that the distance between the pair of erecting rollers is such that a fish can enter in a natural state, and when the fish has entered, the fish is erected. and springs arranged at intervals such that the upstream end of each clamping member in the transport direction faces perpendicularly to the horizontal direction with an interval at least about the thickness of an upright fish body, and the downstream end This device is characterized in that it includes a pair of clamping members whose angle with respect to the horizontal direction gradually decreases toward the end of the fish body.

Effect According to the present invention, an upright means having an upright roller is provided near the downstream end in the conveyance direction of the conveyance means for conveying the fish in a lying state, and the upstream side is provided downstream of the upright means in the conveyance direction. A pair of clamping members are provided which face each other at right angles to the horizontal direction at the end portions and whose angle to the horizontal direction gradually decreases on the downstream side. The fish is conveyed in a lying state with its head facing downstream in the conveyance direction, and while being conveyed while being held by the upright rollers, it once stands up with its belly facing down, and is then moved in a predetermined direction by the pair of holding members. Lying down. As a result, all the fish transported by the transport means can lie down with their dorsal and abdominal sides aligned in a predetermined direction.

Embodiment FIG. 1 is a simplified front view of a device 1 for aligning the dorsoventral direction of a fish body according to an embodiment of the present invention.
The figure is its bottom view. A device 1 for aligning the dorsal and ventral directions of fish bodies is disposed downstream of the fish body alignment and feeding device 2 in the transport direction 3. The fish body alignment and feeding device 2 is
It is composed of a progress stopping means 4 for stopping the fish transported along the transport direction 3, a fish feeding roller 5, a driven roller 6, and an endless transport belt 7. The fish body feeding roller 5 is rotationally driven in the direction of arrow 8 by a drive mechanism (not shown), whereby the fish body stopped by the progress stopping means 4 is moved by the claw 9 fixed to the fish body feeding roller 5. The fish are then sequentially fed one by one on the conveyor belt 7 along the conveyance direction 3 at regular intervals.

The device 1 for aligning the dorsal and ventral directions of the fish body includes an erecting means 10 for erecting the fish body roughly with its belly facing down;
The erecting means 10 includes a holding member 11 that allows the erected fish body to lie down in a predetermined direction with its dorsoventral orientation.
A holding member 11 is disposed subsequent to the holding member 11 .

The upright means 10 is disposed near the terminal end of the fish body alignment and feeding device 2, and has a pair of left and right rotating shafts 14, 1 that are parallel to each other and extend vertically along the transport direction 3.
Erecting rollers 12 and 13 are attached to the upper end of 5, and belt pulleys 16 and 17 are attached to the lower end. The upright rollers 12 and 13 have a structure that allows them to swing left and right along the conveyance direction 3, and are mutually supported by a spring 18.
In a natural state, there is an interval so that the fish can easily enter, and the interval is wide enough to allow the fish to be transported in an upright state. The roller surfaces of the upright rollers 12 and 13 are provided with protrusions around the entire circumference along the axis so that fish bodies can easily engage with them. The belt pulleys 16 and 17 attached to the lower end of the rotating shaft and the belt pulleys 21 and 22 attached to the gears 19 and 20 are connected to the belt 23,
24, and the rotational drive of the gears 19 and 20 is transmitted thereto. gear 1
9 and 20 are in mesh with each other, so that their rotation directions are opposite to each other, and accordingly, the upright rollers 12 and 13 are also rotated in opposite directions. A belt 26 is wound around one gear 20 of the gears 19 and 20 in order to transmit the rotational drive of the motor 25. Therefore, the motor 25 can rotate the upright rollers 12 and 13. In this embodiment, the motor 25
Although the pair of meshing gears 19 and 20 are rotated to drive the upright rollers 12 and 13, separate motors may be provided for the upright rollers 12 and 13 to rotate them individually. .

The holding member 11 disposed subsequent to the upright means 10 has two thin plates 30 and 31 erected facing each other along the conveying direction 3, and the opposing surfaces are spaced at a constant interval approximately the thickness of the fish body. I'm keeping it. The opposing surface has an angle θ (third
(see figure) is gradually changing. The angle θ is approximately 90° with respect to the mounting surface at the starting end of the holding member 11, but at the terminal end, it is an angle necessary for the fish to reliably lie in the direction in which the thin plates 30, 31 are inclined. ing.

In this way, the holding member 11 is configured to face the horizontal direction at right angles near the upstream end in the transport direction, and the angle to the horizontal direction gradually decreases toward the downstream end. .

The operation of the device 1 having such a configuration for aligning the dorsal and ventral directions of fish bodies will be described. motor 25
When energized, the rotational drive is transmitted to the gear 20 by the belt 26, and the gear 20 is rotationally driven. A belt pulley 22 is attached to the gear 20, and a belt 24 is wound around the belt pulley 22 and the belt pulley 17 attached to the rotating shaft 15, so that the rotational drive of the gear 20 is transmitted to the rotating shaft. , Therefore, the upright roller 13 is driven to rotate. The other erecting roller 12 cannot grip and convey the fish body unless its rotational direction is opposite to that of the erecting roller 13. For this purpose, a gear 19 is meshed with a gear 20 that is rotationally driven by a motor 25 via a belt 26. Therefore, the directions of the gears 19 and 20 are opposite, and therefore the rotational drive transmitted to the rotating shaft 14 via the belt 23, that is, the rotational drive of the erecting rollers 12 is opposite to the rotational direction of the erecting rollers 13. It rotates in the same direction. The fish 40, which has now been sent lying down with its head at the top at a fixed interval from the fish alignment and feeding device 2, enters between the rotationally driven upright rollers 12 and 13. As the fish body 40 enters, the upright rollers 12 and 13 open left and right along the conveyance direction 3, as shown in FIG.
The force of the spring 18 presses the fish body 40 from the left and right sides. The fish body 40 pressed by the upright rollers 12 and 13 is rotated in the transport direction 3 by the rotational drive of the upright rollers 12 and 13, as shown in FIG.
The patient stands up with his abdomen facing down while being transported downstream along the road. As shown in FIG. 5, when the fish 40 is lying down, the center line of the fish 40 passing from the back to the abdomen has an angle of θ1, and the abdomen of the fish 40 is heavier than the back. Since the center of gravity of the fish body 40 is located in the abdominal direction, when the fish body 40 is pressed from the dorsal side and the ventral side, an upward force acts on the dorsal side, and a downward force acts on the ventral side. At this time, the upright rollers 12 and 13 are rotationally driven, so that the fish body 40 gradually stands up with its abdomen facing down while moving forward along the transport direction 3.

The fish body 40 erected by the erecting means 10 is sent between the thin plates 30 and 31 of the holding member 11 in an erect state. The fish body 40 fed between the thin plates 30 and 31 is inclined along the inclination of the thin plates 30 and 31, and the fish body lies on its side behind the terminal end of the holding member 11. As described above, the fish body 40 transported from the fish body alignment and supply device 2 is moved to the upright means 10.
After being made to stand up, the subject is made to lie down with the dorsal and ventral sides aligned in a predetermined direction using the holding member 11.

Effects As described above, according to the present invention, it is possible to align the dorsal and ventral directions of all the fish bodies transported one by one in a predetermined direction, and the structure is simple and compact. . Therefore, it becomes possible to accurately process the subsequent fish.
