Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a head-direction device for fish.

[Conventional techniques and their problems] Traditionally, fresh or defrosted fish such as horse mackerel, sardines, saury, small mackerel, and capelin, which are popular among the public, are processed at high speed and in large quantities by cutting the heads, cutting the bellies and backs, The machines that remove the backbones are all fed by human hands on a caterpillar-shaped belt while keeping an eye on the direction of the fish. Therefore, the working capacity of one person who feeds fish by placing them on a caterpillar belt cannot exceed 60 fish per minute.
The work is carried out by 4 to 20 supply personnel assigned to the cutting machine. For this reason, the more cheap small fish are sold at +JJ, the more labor is required and the labor costs increase, so fish are not cut into pieces and are sold in their original form, causing them to be taken away from households. If we were able to achieve mass processing that requires no labor costs, sardines and other fish would be available to households at low prices, which would help lower the landing prices of fishing boats that are suffering from poverty, and prevent Japanese people from turning away from fish. It is thought that it can be done. The reason unmanned labor-saving machines have not progressed is that they cannot line up large quantities of fish heads in a fixed direction at high speed. This is because arranging the fish with their heads at the tip is the basis for automatically feeding large quantities onto the caterpillar.

It is an object of the present invention to solve the above-mentioned problems and provide an apparatus for arranging fish heads in a uniform manner and at high speed.

[Means for solving the problem] The structure of the fish body is such that it moves forward in water, and the entire fish body has a streamlined shape to minimize water resistance. In other words, the skin, scales, and gill organs on the surface have a shape and structure that reduces water resistance when moving, creating such resistance that the fish cannot move backwards. The present invention utilizes the common characteristics of these fish, and has succeeded in aligning the heads with the tip, regardless of the quality of the q+ of the horns, changes in resistance on the surface of frozen fish, or differences in large or small amounts of fish. It is something.

In order to solve the above-mentioned problems and achieve the object of the invention, the fish head-directing device according to the present invention is characterized by having the following configuration. That is, a supply conveyor that has an upward angle and is driven in the traveling direction, and a sliding conveyor that is located in front of and below the supply conveyor and has a downward angle and is driven in the opposite direction to the traveling direction and that moves back and forth at high speed. It is characterized by having a reversing sliding plate disposed from the rear of the sliding conveyor to the F section, and a delivery conveyor located below the front of the sliding conveyor 2 and the reversing verri plate, having an upper surface angle, and driving in the advancing direction. shall be.

[Example] The present invention will be described in detail below with reference to the embodiments shown in the drawings.] Fig. 1 is a front view of one embodiment of the fish head head turning device according to the present invention, and Fig. 2 is a front view of the same model. The front view and FIG. 3 are explanatory diagrams of the main parts of the unreleased j. Here, 1 is a supply conveyor, 2 is a sliding conveyor, 3 is a reversing sliding plate, 4 is a delivery conveyor, and 5 is a pedestal.

The supply conveyor 1 is driven in the advancing direction with an upward angle.

The supply conveyor 1 has a pin at one point on the E part of the pedestal 5, and one of the turnbuckles 11 (left-hand thread and right-hand thread) is bolted to one end of the supply conveyor 1 so that the surface is inclined upward according to the direction of travel. Then bolt the lower part of the turnbuckle 11 to the plate and set the angle of the supply conveyor 1 to about 20°.
to degree. The moving wheels of the supply conveyor 1 are driven by the motor 12 via the moving wheels of the delivery conveyor 4, and the belt is driven in the traveling direction.

In order to place fish on the supply conveyor l, a negative supply cradle 13 is provided to store the fish, and the fish may be supplied from here, or the fish may be fed from a chute, or from another commonly used held conveyor. Sometimes they are sent. In order to make any angle suitable, the turnbuckle 11 is used as an auxiliary tube.

The state of supply conveyor 11 is horizontal, some are 1 fish first, and some are 1 animal first. It is corrected and falls onto the L of the sliding conveyor 2. The fish are moved in the direction of arrow A by the supply conveyor l and fall onto the sliding conveyor 2. The belt speed of the supply conveyor 1 shall be 50 m/min or more. Fish are fed with some heads first and some tails first, but when they ride on the belt of the feeding conveyor, most of the fish move vertically, or longitudinally, due to the speed of the belt. and falls onto the sliding conveyor 2.

The sliding conveyor 2 is located below and in front of the supply conveyor 1, has a downward angle, is driven in a direction opposite to the direction of movement, and reciprocates at high speed.

The sliding conveyor 2 has a downward angle of about 11 degrees in the traveling direction,
The receiver of the sliding conveyor 2 slides while being sandwiched between the F roller 22 and the upper roller 23. Rectangular fixing plates 21 are attached to both inner sides of the pedestal 5 with bolts. A stepped roller piece is attached to the plate by idly rotating on the long shaft of the lower roller 22 so as to sandwich the side plate of the conveyor body of the sliding conveyor 2 in order to slide the sliding conveyor 2 at a downward angle.

Here, the shaft of the lower roller 22 is passed through the frame 5. The upper roller 23, which presses down from above, is loosely installed on a short shaft. The shaft of the upper roller 23 is connected to the roller fixing plate 21 installed on both sides.
Support it with a port pin.

A rod 24 is installed as a shaft at the lower end of the sliding conveyor 2, and a crankshaft 25 is rotated by a motor 26, so that the sliding conveyor 2 is reciprocated as indicated by a reciprocating arrow B.

Sliding conveyor? The belt travels in the direction of arrow C, which is opposite to the traveling direction of the supply conveyor 1. The belt speed of the sliding conveyor 2 is 15 m to 16 m per minute. The moving wheels of the sliding conveyor 2 are driven by a motor 27. In addition, the reciprocating length of the sliding conveyor 2 is approximately 60 m+s, which is approximately 2 times per minute.
Slide 00 times. That is, the sliding conveyor 2 moves back and forth while moving in the direction of arrow C.

Fish falling onto the sliding conveyor 2 from the supply conveyor 1, head first, slide and pass over the sliding conveyor 2, reach the delivery conveyor 4-hi, and ride on it. In addition, when a fish falls onto the sliding conveyor 2 with the tail first, the sliding becomes obsolete due to the brakes applied by the scales on the fish body, and the reverse feeding of the belt and the sliding of the sliding conveyor 2 cause the fish to fall again. Due to the action of scales, etc. that move in the head direction, the ball quickly moves in the opposite direction and falls onto the reversing sliding plate 3 with the head first. Then, the fish body turns its head, slides onto the belt of the delivery conveyor 4, and is sent out. When a fish slides on the sliding conveyor 2, a fish with a good degree of degree will slide well and move quickly, but a fish with a bad degree of degree will not slide well and will move slowly. The sliding distance is different each time, but in each case, the fish's turning effect is accurate - 0 shots, 1 shot! In the fish head turning device according to item I], by sliding the heald of the sliding conveyor 2 at high speed, the effect of turning the fish body of the sliding conveyor 2F- can be made accurate.

Here, sliding the fish on the sliding conveyor 27 more than 200 times per minute has the function of repairing the fish in the vertical direction and also moving the fish that are supplied in large quantities to the belt. It has the effect of making the fish land on the surface, and even when the fish are overlapping, the effects of the fish's scales, etc. in contact with the fish appear, and the fish move in the forward direction and in the opposite direction.

When the sliding conveyor 2 is a water moth, it is clear that the fish placed on -F move at the same speed in the forward direction and in the opposite direction due to the action of biological structures such as scales, skin, and gill covers. However, even if the angle of the sliding conveyor 2 is increased downward in the direction of travel, that is, the slope is increased, the fish will continue to move in the direction of travel and in the opposite direction. ! ! If the angle does not change and the angle becomes 1;, the speed in the forward direction will be faster than the speed in the opposite direction. The angle is about 10 to 12 degrees.

Sliding conveyor 2! - The moving speed of the fish is specifically as follows. The sliding speed of the sliding conveyor 2 is 12 m/min.
The speed of the fish supplied from the supply conveyor 1 in the forward direction is lower than the speed of the supply conveyor 1, approximately 30 m/min, and the speed of the sliding conveyor 2 in the opposite direction is 1/min.
If the distance is 5 m, the speed of the fish in the direction of travel is 12 + 3.
0-15 or 27 m/min and the speed of the fish in the opposite direction is +2+15 or 27 m/min. Thus, while the speed of the sliding conveyor 2 is 15 m/min, the traveling speed of the fish placed on the sliding conveyor 2-1 is 27 m/min, which means that the fish travels about twice as fast.

The reversing sliding plate 3 is arranged from the rear to the bottom of the sliding conveyor 2. The fish which falls head first onto the reversing plate 3 from the sliding conveyor 2 turns around, turns its head in the direction of travel, slides onto the belt of the delivery conveyor 4, and is sent out.

The delivery conveyor 4 is located in front of and below the sliding conveyor 2 and the reversing plate 3, has an upward angle, and is driven in the advancing direction. The delivery conveyor 4 has an upward angle of about 20 degrees, and the belt is driven in the same traveling direction as the supply conveyor 1, that is, in the direction of the arrow. The moving vehicle of the delivery conveyor 4 is driven by a motor 12. The lower end of the delivery conveyor 4 is attached to the lower bracket of the pedestal 5 with bolts. A turnbuckle 41 is bolted to the lower center of the delivery conveyor 4, and the lower end of the turnbuckle 41 is bolted to the bed, and the angle of the conveyor is adjusted according to the usage situation. Note that, in terms of performance, it is desirable that the belt speed of the delivery conveyor 4 be 35 to 50 m/min.

Various types of conveyors can be used for the supply conveyor 1, the sliding conveyor 2, and the delivery conveyor 4, but a belt conveyor is most suitable among them, and a belt having rough rough edges and vertical stripes is suitable.

Since the fish sent out from the delivery conveyor 4 has its head facing in a certain direction of force, the next process is to cut off the head, cut the abdomen and back, and remove the backbone without any human intervention. Send it to a machine or pack it in a box.

[Effects of the Invention] Since the fish head turning device according to the present invention is constructed and used as shown in E, it is possible to arrange a large number of fish heads in a fixed direction at high speed, without requiring any human effort. This has the effect of cutting the head, cutting the abdomen and back, removing the spine, and then sending it to a processing machine or packing it in a box.
