DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a fish body orientation device, and more particularly, the present invention relates to a fish body orientation device, and more particularly, to
The present invention relates to a device for aligning directions.

In the production of canned fish, etc., it is necessary to direct all the fish to be fed in the same direction when feeding the fish to a fish processing machine that cuts off the head, tail, etc. of the fish and processes them. Therefore, one fish is placed in each fish tray of the cutter slat conveyor device that transports the fish to the fish processing machine.
Various devices have been proposed to orient a large number of fish in a specific direction as a pre-process to the process of arranging fish one by one in a specific direction.

Conventionally, devices for directing fish in a fixed direction include a vibrating punching plate device that uses the directionality of the fish's scales to align the direction of the fish, and a multi-stage inclined conveyor device that arranges multiple conveyors in a stepped manner. However, these conventional devices have imperfect orientation of the fish body and are also very expensive. Therefore, in the end, it was necessary for a person to align the direction of the fish and place them on the fish tray of the above-mentioned cutter slat conveyor device.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a fish body direction alignment device that reliably aligns a plurality of fish bodies in a predetermined direction in a pre-processing process when a large number of fish bodies are carried into a fish body processing machine.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The fish body orientation device of the present invention will be described in more detail below with reference to preferred embodiments shown in the accompanying drawings.

1 and 2 show a fish body alignment device A including a fish body orientation device of the present invention. The fish orientation device includes a conveyor device 10, which is a belt conveyor-like structure. That is, the device 10 includes two belt pulleys 11a and 11b spaced apart,
One belt pulley 11a is arranged at a higher position than the other belt pulley 11b. A belt 12 made of plastic net is attached to these two belt pulleys 11a and 11b in a hanging manner, and the belt pulley 11b is operatively connected to a suitable drive motor (not shown) so that it can rotate. It is said that

In this conveyor device 10, a stainless steel plate 13 is provided on the back side of the upper belt portion of the belt endlessly hung between the two belt pulleys 11a and 11b so as to face almost the entire area of the upper belt portion. installed. The upper end of the conveyor device 10, that is, the belt pulley 11a
A water spray device 14 that sprays water in a shower-like manner toward the belt 12 is installed directly above the side end, and the water spray device 14 sprays water from the surface of the belt portion between the plate 13 and the upper belt portion. Enough water is flowing to form a water film at lower locations. Furthermore, the conveyor device 10 includes a belt wheel 11.
A rotary brush 15 for cleaning the surface of the belt 12 is installed near b and along the lower belt portion.

In such a conveyor device 10, the belt 12 is formed from a plain weave plastic net having a wire diameter of 0.7 mm, as shown in FIG. The belt 12 in this conveyor device 10 is not necessarily limited to plain weave, but may include satin weave,
It may be a twill weave or a double weave, but a plain weave is most suitable for the reasons described below.

The upper end of this conveyor device 10, ie, the belt wheel 11a side, is the side that supplies fish, and therefore there is a blade between the inside of the balance tank 16 installed below, which receives fish, and the supply side of the conveyor device 10. A conveyor device 17 is arranged, whereby a large number of fish are conveyed successively to the supply side of the conveyor device 10.

On the other hand, at the lower end of the conveyor device 10, that is, at the exit side of the fish that has slipped off the belt 12 from above, there are two transport conveyors 18 for one conveyor device.
a and 18b are arranged adjacent to each other in parallel. At the exit end of one of the conveyors 18a, a corrugated chute 19 slightly inclined is arranged extending in the conveying direction, and at the exit end of the other conveyor 18b, a chute 19 is disposed extending from the outlet end to the lower side of the chute 19. A chute 20 made of a corrugated plate is arranged, which extends in a direction opposite to the conveyance direction while being curved. Water discharge portions 20a and 20b for forming a water film on the chute 19 and 20 are provided directly above the vicinity of each outlet end of the two conveyors 18a and 18b.

Below the exit side ends of these two corrugated sheet chutes 19, 20, one alignment conveyor device 22 is installed which extends in a direction perpendicular to the chute. On the belt 23 of this alignment conveyor device 22, the fish from the conveyor 18a are placed on one half of the side.
In the other half, the fish from the conveyor 18b are arranged with their heads facing outward. On both sides of this alignment conveyor device 22, as shown in FIG. 2, cutter slat conveyor devices 24 are arranged in parallel for feeding the fish into a fish processing machine 23 where the head and tail of the fish are cut and processed. It is installed in In FIG. 2, reference numeral 25 indicates an empty can chute, and reference numeral 26 indicates a conveyor device for manual filling.

The fish body orientation device of the present invention operates as follows using the above-mentioned conveyor device 10 and the like.

A large number of fish are randomly fed (thrown) onto the belt 12 at the upper end of the conveyor device 10 by the vaned conveyor device 17 . The belt 12 of the device 10 is then moved downwards at a relatively low speed. Therefore, the force of the fish fed onto the belt 12 to slide down the belt surface increases due to the addition of the force of the fish trying to fall on the belt due to its own weight and the force of descent due to the movement of the belt.
Coupled with this action, the water spray device 14
Since water is sprinkled onto the belt 12 from the fish and a water film is formed between the belt surface and the plate 13 arranged on the back surface, the friction between the fish and the belt is reduced and the fish begin to slide off. However, a fish's scales are arranged from the head to the tail, so when the fish tries to slip off the tail, the scales get caught in the weave of the plain-woven belt and are corrected in the direction in which they are most likely to slide downwards. movement, resulting in belt 12
In the middle of the water, most of the fish slide down with their heads down.

In order for the fish to slide down on the belt 12 in this way, the angle of inclination α of the conveyor device 10 is important, but the angle α should be approximately 35 degrees. ), or adjusted by freshness. Further, the reason why it is preferable that the belt 12 is made of plain weave is that it is likely to cause slippage in only one direction, corresponding to the directionality of fish scales.

In this way, the belt 12 of the conveyor device 10
All the fish that have slid down are transferred head first onto the respective transport conveyors 18a, 18b, and then onto the belts of the alignment conveyor device 22 by the corrugated plate chutes 19, 20 at their respective outlet ends. At this time, the curved corrugated chute 20 at the outlet end of the conveyor device 18b reverses the direction of the fish so that it is placed on one side of the belt 23 of the alignment conveyor device 22, that is, on the right half as seen in FIG. Transfer. On the other hand, the fish sent by the conveyor device 18a are transferred to the alignment conveyor device 22 in the same direction.
2. Transfer to the other side of the belt 23, that is, the left half as seen in FIG. 2, with your head facing outward.

As a result, a large number of fish are arranged in two rows on the belt of the arrangement conveyor device 22, and all the fish in each row are arranged facing outward. When the fish arranged in this way are conveyed by the arrangement conveyor device 22, the operator 27 pulls the fish on the arrangement conveyor device 22 directly into each fish body tray of the cutter slat conveyor device 24 in front. Transfer to. In order to facilitate such work, it is preferable that the surface of the belt 23 of the alignment conveyor device 22 and each fish body tray of the cutter slat conveyor device 24 be located in the same horizontal plane.

Furthermore, the belt 23 of the alignment conveyor device 22 is
It is preferably constructed from a plain weave plastic net similar to the belt 12 of the conveyor system 10 described above. With this configuration, the operator 27 can simply align the fish with their heads facing outward and slide them forward on the alignment conveyor device 22 using the directionality of their scales. can be transferred to each fish tray of the cutter slat conveyor device.

In the fish body alignment device A described above, the fish body processing machine 23
In this example, two units are installed, but of course one unit may be used. However, in that case, the conveyor device 1
8b is unnecessary, and the width of the belt 12 of the conveyor device 10 for aligning the direction of the fish is made to match the belt width of the conveyor 18a.

Furthermore, in the conveyor device 10 described above, the belt 12 is moved in the same direction as the direction in which the fish slide down, that is, from above to below.
The belt pulley 11b may be rotated so as to move from the bottom to the top. According to such movement of the belt 12, a force acting on the fish placed on the belt causes it to fall on the belt due to its own weight. In such a state, if the belt 12 is moving in the direction completely opposite to the direction of the descending force acting on the fish, the inertial force that tries to keep the fish in that position will act further, causing the water spray from the water spray device 14 to Coupled with the water film formed between the belt surface and the plate 13, the force that causes the fish to slide becomes greater than the frictional force between the fish and the belt, and the fish begins to slide. As a result, as described above, the direction of the fish is aligned by the interaction between the directionality of its scales and the plain weave belt. In this way, the belt in the fish orientation device may move in any direction.

As explained above, according to the fish body orientation device of the present invention, it is possible to reliably align all randomly supplied fish in a certain direction, and the number of personnel required to perform orientation adjustment work during the subsequent automatic processing of fish can be greatly reduced. In addition, the device can be manufactured at a very low cost.
