Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a fish body alignment and conveyance device that uses so-called vibration to align fish bodies supplied in different directions and transport them with their heads at the top. .

[Conventional technology]

In order to process fish, it may be necessary to line up a large number of fish in front of each other and align all of their heads forward.

An example of a device that uses so-called vibration to perform such fish body alignment is the
It is disclosed in Publication No. 170478. This device is configured to move the head of the fish toward the front and rear opening ends by horizontally reciprocating a plate having a friction surface on its upper surface.

[Problem that the invention seeks to solve]

However, the above-mentioned device simply distributes the supplied fish bodies in the front-back direction, and the fish bodies facing in the opposite direction to the predetermined conveyance direction are dropped from the device, so the efficiency is very low. In addition, since the fish are sorted in the front-rear direction on one plane, a large area is required to eliminate overlapping of the fish and to reliably sort them, making the device large.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a fish body alignment and conveyance device that can line up all of the supplied fish bodies in the same direction, and can also do so reliably with a small device.

[Means for solving problems]

The fish body aligning and conveying device of the present invention is for supplying fish bodies, has two side surfaces along the fish body conveyance direction and a bottom surface, and is open in the front and back, and has a bottom surface that intersects with the fish body conveyance direction. a sorting section that has a transport plate with a large number of linear grooves arranged in parallel on its surface; and a gutter-like section that is provided below the sorting section and receives fish from it, which is in the direction of the fish conveyance direction from the sorting section. a sorting trough that is long and has openings at the front and rear, and further has a conveying plate on the bottom surface of which is lined with many linear grooves that intersect with the direction of fish conveyance; It is a gutter-like thing that has an opening at the front in the direction of fish transport, and has a straight claw on the bottom that projects obliquely upward in the direction of fish transport. a chute that guides the fish from the rear opening of the sorting trough to the carrying out trough with the direction reversed, and at least the sorting section and the sorting trough; and a drive mechanism that reciprocates the carry-out trough in the front-back direction of the fish conveyance direction.

[Effect]

The fish bodies supplied to the sorting section are sorted forward or backward in the direction of fish body conveyance according to the direction of the head by the engagement of the scales with the grooves of the reciprocating conveyance plate, and are then supplied to the sorting trough.

The fish fed to the sorting trough are further reliably sorted in the direction the head is facing by the engagement of the scales with the grooves of the reciprocating transport plate, and the fish with the head facing forward will be sorted into the opening in front. Fish bodies with their heads facing backwards are carried out from the rear opening, turned forward by the chute, and fed to the carry-out trough in the same direction.

As a result, all fish bodies are supplied to the carry-out trough with their heads facing forward, and the fish bodies are quickly transported forward by the reciprocating transport plate, and fish bodies with their heads aligned forward are carried out from the opening of the carry-out trough. be done.

〔Example〕

FIG. 1 is a schematic side view showing a fish body aligning and transporting device according to an embodiment of the present invention, FIG. 2 is a schematic plan view thereof, and FIGS. 3 to 5 are, respectively,
FIG. 2 is a sectional view taken along lines -, -, - in FIG. 2;

Four elastic plates 22 and 23 (the other two
supply trough 40 (not shown in the figure)
However, the frame 30 is supported by four elastic plates 31 and 32 (the other two are not shown in the figure) so as to be swingable in the front and rear directions of the fish transport direction D, respectively. In this case, the elastic plates 22 and 23 form an acute angle forward (for example, 70°) with the bottom surface of the supply trough 40.
The elastic plates 31 and 32 are attached substantially vertically. These elastic plates 22, 23, 31, 3
2 is made of a hard and elastic material such as FRP or steel plate.

Further, a motor 20 and a crank device 21 are attached to the frame 10, and the rotational movement of the motor 20 is controlled by the crank device 21.
It is changed to a reciprocating motion like arrow A in 4,25,
It is transmitted to the supply trough 40 and the frame 30, respectively. As a result, the supply trough 40 is reciprocated in the front and back direction of the fish transport direction D, as shown by the arrow B, between the illustrated position and the position where the elastic plates 22 and 23 stand approximately vertically. Since the mounting angles of the elastic plates 22 and 23 are acute as described above, they are driven so as to be pushed diagonally upward in the fish transport direction D during forward movement. On the other hand, the frame 30 is
Since the mounting angles of the elastic plates 31 and 32 are substantially perpendicular, the elastic plates 31 and 32 are driven to reciprocate almost evenly in the front and back direction of the fish transport direction D, as shown by arrow C. This frame 30 includes an extension part 50, a distribution part 60, a distribution trough 7
0, a carry-out trough 80, and chute 91, 92 are attached, and therefore, these are driven to reciprocate as shown by arrow C integrally with the frame 30.

The supply trough 40 is for conveying the fish bodies 1 supplied therein in a vertical line, and has a bottom portion 4.
It is shaped like a gutter with shelves 46 on the left and right sides of 7, has an opening 41 in front of the bottom 47, and has a conveyance plate 43, which will be described later, on the bottom. The extension part 50 is a gutter-shaped part that supplies the fish bodies 1 from the supply trough 40 to the distribution part 60, and has openings at the front and rear.
It also has a conveyance plate 52, which will be described later, on the bottom surface.

The sorting section 60 distributes the fish 1 supplied thereto forward or backward in the fish conveying direction D according to the direction of the head, and has two side surfaces 61 and 62 along the fish conveying direction D and a bottom surface 63. Consisting of
In the center of the bottom surface 63, there is a chevron-shaped partition 6 extending in the fish transport direction D and having a stop plate 65 in the front.
4 is provided, and conveyance plates 66, which will be described later, are provided on the left and right sides thereof. The distribution trough 70 is
It is located below the sorting section 60 and distributes the fish 1 from the sorting section 60 back and forth again according to the direction of the fish's head. It is long and has openings 71 and 72 at the front and rear, respectively, and further has a conveying plate 74, which will be described later, on the bottom surface. Unloading trough 80
is located below the sorting trough 70 and carries out the fish 1 from the sorting trough 70, and is shaped like a gutter, is inclined with the front facing upward, and has an opening 81 in the front. , and has a conveyance plate 83, which will be described later, on the bottom surface. The reason why the carry-out trough 80 is inclined is to improve usability by reducing the height difference from the position where the fish body 1 is introduced to the position where it is carried out, and to reduce the installation area of the device.

FIG. 6 is a plan view showing the conveying plate of FIG. 2 in more detail. The front end portion 74a of the transport plates 43, 52 and the transport plate 74 and the surface of the transport plate 83 are provided with a fish body transport direction D as shown in cross section in FIG.
A linear claw 100 protruding diagonally upward.
are arranged in parallel so as to be perpendicular or diagonally intersecting the fish transport direction D. However, transport plate 7
Although the claw 100 on the rear end portion 74b of 4 has the same structure as above, the direction of conveyance thereof is backward, that is, the opposite direction to the above-mentioned fish body conveyance direction D, so that the claw 100 protrudes toward the rear. Note that the claws 100 as described above are, for example, conveyor plates 43, 52, 74,
83 is made of a material with a certain degree of hardness such as polypropylene, plastic, aluminum, etc.
It can be formed extremely easily by simply making a large number of linear cuts 101 diagonally downward (for example, at about 45 degrees) on the surface.

On the other hand, as shown in FIG. 8 in cross section, linear grooves 102 having, for example, a V shape are formed on the surface of the portions of the transport plates 66 and 74 other than the front and rear ends 74a and 74b in the fish body transport direction. A large number of them are arranged in parallel so as to be orthogonal to D. In this case, the cross-sectional shape of the groove 102 is preferably substantially symmetrical from the viewpoint of equalizing the engagement force with the scales regardless of whether the fish body 1 is facing forward or backward. Also, the depth may be shallow. Note that such a groove 102 can be formed, for example, by using the same materials as those mentioned above for the conveyor plates 66 and 74.
It can be formed extremely easily by polishing the surface in a straight line with paper.

Next, the overall operation of this device will be explained with reference mainly to FIG. When the motor 20 is driven to reciprocate the above-mentioned parts and a large number of fish bodies 1 are fed to the supply trough 40 in arbitrary (that is, random) directions, the width W ₁ of the bottom part 47 is longer than the body length of the fish bodies 1. The fish bodies 1 fall to the bottom 47 and are arranged in tandem as shown in the figure. However,
The head of the fish 1 may be oriented in the fish transport direction D, or vice versa. and conveyor plate 4
The claws 100 on the surface of the fish 1 protrude obliquely upward in the fish transportation direction D, so when the supply trough 40 moves forward, the claws 100 on the surface of the fish 1 strongly engage so as to bite into the scales and flesh of the fish 1. Because there is almost no engagement during the backward movement, and because the supply trough 40 is driven diagonally upward in the fish transport direction D during the forward movement, and is driven away from the fish 1 in the opposite direction during the backward movement, The fish 1 is transported toward the opening 41 with a large transport force, that is, at a high transport speed, regardless of whether its head is in the front or rear direction. Further, even if a plurality of fish bodies 1 are stacked vertically, they are arranged one by one in a column. Moreover, since the bottom surface of the bottom portion 47 near the opening 41 is inclined so that the front side is upward,
Overlapping of the fish bodies 1 when being carried out from the opening 41 is more completely prevented.

Incidentally, if necessary, a chevron-shaped partition 44 may be provided on the surface of the conveyance plate 43 to distribute the fish bodies 1 to the left and right, or a fish body conveyance plate 44 may be provided on the surface of the conveyance plate 43 to bring the fish bodies 1 closer to the center. A large number of V-shaped claws extending in direction D may be provided. Furthermore, a fish retainer 4 is provided on the shelf 46 to facilitate the supply of fish 1.
5 may be attached.

The fish bodies 1 carried out in a column from the opening 41 are
It is supplied to the extension part 50 which is reciprocated back and forth, and is transported by the transport plate 52 having the claws 100 similar to those described above in substantially the same manner as described above, to the sorting part 6.
0.

The fish 1 supplied to the sorting section 60 is sorted to either the left or right by the chevron-shaped partition 64 and the stop plate 65, and the width W ₂ of the left and right transport plates 66 of the partition 64 is narrower than the body length of the fish 1. Therefore, the fish body 1 is placed on the conveyance plate 66 while facing in the front-rear direction. The sorting section 60 is also reciprocated back and forth, and since the surface of the conveying plate 66 is not provided with claws 100 but with grooves 102 as described above, the fish 1 is directed with its head facing. It is conveyed to the direction and dropped from the sorting section 60. This is because the grooves 102 of the conveying plate 66 engage with the tips of the scales growing toward the tail of the fish body 1, so that the conveying force acts in the direction of the head. In other words, the fish 1 are distributed to the front or rear in the fish transport direction D according to the direction of their heads, and then supplied to the distribution trough 70.

The sorting trough 70 is also reciprocated back and forth, and since the central surface of the conveying plate 74 is provided with a groove 102 similar to that described above, the fish 1 are similarly moved in the direction in which their heads are facing. transported. Therefore, even if a fish 1 with its head facing backward due to overlapping fish bodies 1 is dropped to the front side of the sorting section 60, the fish 1 will be dropped into the sorting section 60.
and is conveyed to the rear of the sorting trough 70. Conversely, when the fish 1 with its head facing forward is dropped to the rear side of the sorting section 60, it is similarly transported to the front of the sorting trough 70. In this way, the fish body 1 is transferred between the sorting section 60 and the sorting trough 70.
Since the fish are sorted twice in stages, the fish 1 can be reliably sorted in the direction their heads are facing in a narrow space without increasing the length of the sorting trough 70. Therefore, the device can be made smaller and its installation area can be reduced.

When the fish 1 with its head facing forward reaches the front end 74a of the transport plate 74, the claw 100 protrudes forward on its surface, so the fish 1 is carried out through the front opening 71 at a high transport speed. and the unloading trough 8 is carried out through the chute 91 in the same direction.
0 near the front end. On the other hand, when the fish 1 with its head facing backward reaches the rear end 74b of the transport plate 74, the claws 100 protrude rearward from the surface of the fish 1, so that the fish 1 moves at a high transport speed through the rear opening. 72, and was carried out from chute 92.
(see FIG. 1), the paper is fed into the vicinity of the rear end of the carry-out trough 80 in the reverse direction, that is, with its head facing forward.

Therefore, all the fish bodies 1 are supplied to the carry-out trough 80 with their faces facing forward. The carry-out trough 80 is also reciprocated in the front-rear direction, and the surface of the transport plate 83 is provided with claws 100 that protrude forward.
is quickly transported out of the opening 81 at a high transport speed. This is intended to improve work efficiency. In this way, all the fish 1 supplied in any direction of the supply trough 40 are transferred to the discharge trough 8.
The heads are all aligned forward and carried out from the opening 81 at No. 0.

Although the above embodiment has been described using an example of a device equipped with the supply trough 40, the supply trough 4
Of course, even if the fish bodies 1 are supplied to the sorting section 60 by some means other than zero, the heads of the fish bodies 1 to be carried out from the carry-out trough 80 can be aligned in the same direction. However, the above-mentioned supply trough 4
0 and its drive mechanism, a large number of fish 1 can be efficiently and quickly sorted by the sorting unit 6 regardless of their orientation.
Since it is possible to supply the fish to zero, it is possible to further improve the working efficiency of fish body alignment.

In addition, the above-mentioned supply trough 40 and the distribution section 6
0, the sorting trough 70, the unloading trough 80, etc. may be driven by separate drive mechanisms as described above.

〔Effect of the invention〕

As described above, according to the present invention, all the supplied fish bodies can be aligned in the same direction and carried out, and therefore the efficiency of fish body alignment is very high. Moreover, since the sorting of the fish bodies in the front-rear direction is carried out doubly in two stages, the sorting section and the sorting trough arranged above and below, it is possible to reliably line up the fish bodies with a small device.
