Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an apparatus for feeding small fish onto a steamer with a uniform thickness.

[Prior Art] In the process of processing small fish, such as boiling and drying dried sardines, sardines, whitebait crepe, etc., the process of supplying small fish uniformly and thinly to a steamer or a net conveyor is often carried out.

As shown in FIG. 1, a water steamer has a square or rectangular frame 1 made of wooden blocks, etc., and a sheet-like net 2 stretched over the bottom to prevent small fish from falling into it. Wash the small fish to remove scales, slime, etc., spread them evenly on a bamboo steamer, assemble the ten or so steamers 3 on the assembly stand as shown in Figure 2, and boil them once in a boiling pot. Then, the boiled material is spread out again one by one and dried in the sun.
Transfer to drying duct and dry.

At present, feeding small fish into a steamer in a uniformly thin manner as described above is generally done almost entirely by hand.

Figure 2 shows the process of manually leveling small fish on a bamboo steamer. First, a steamer 3 is placed on the soroban chute 4, and small fish from a fish tank are scooped up with a net and supplied in a required amount onto the steamer 3. Hold this bamboo steamer 3 in your hand and move it up and down several times while tilting it up and down and diagonally using the water surface of the cleaning tank as a boundary to even out the small fish. This work involves cleaning and leveling the small fish uniformly, but it requires considerable skill to level the small fish uniformly and without spots, and it is usually done by two people facing each other. The drawback was that it required a lot of labor and time.

[Purpose] The present invention is configured so that small fish can be evenly leveled on a steamer and washed in this process, so that the small fish can be evenly spread, evenly, and more efficiently with greater accuracy than manual labor. To provide a device for uniformly feeding small fish arranged in rows.

[Configuration] Hereinafter, embodiments of the present invention will be described based on the drawings.

The apparatus shown in FIG. 3 that uniformly supplies small fish to a steamer is equipped with a supply means for supplying a fixed amount of small fish per unit time, a supply means for sending the small fish together with dispersion water to the steamer 17, and a supply means for supplying dispersion water to the supply means. Water supply means 7
and a conveyor 8 for moving a steamer 17 that receives small fish and dispersed water sent out from a supply means.

The supply means consists of a fish feeder 5 and a supply duct 6, and the fish feeder 5 uses a fish pump 9 and a fish pump 9 to sort and separate small fish that are transferred together with the water from the fish tank from the water. A sorting machine 10 is provided, and a net conveyor 11 is provided below the sorting machine 10 to transfer a fixed amount of small fish.

The sorting machine 10 has a grid material 12 for sorting large and small fish.
U and 12D are installed in a double slanted manner, and small fish pass through the upper grid 12U, slide on the lower grid 12D, and fall onto the net conveyor 11. Large fish do not pass through the upper grid and are removed to the upper grid 12U. A tank 13 is provided below the upper and lower grids 12U, 12D to remove water flowing down through the grids 12U, 12D.

A drainage tank 14 is located below the net conveyor 11.
is provided, and water flowing down from the net conveyor 11 is removed from the drainage tank 14. The net conveyor 11 is operated in synchronization with the movement of the steamer. Small fish are sent to the supply duct 6 only when the net conveyor 11 is operated. Net conveyor 1
If the operating speed in step 1 is increased, the amount of small fish sent out will increase. In order to more accurately quantify the amount of small fish sent out per unit time by the net conveyor 11, a control member 15 is disposed above the net of the net conveyor 11, as shown in FIG.

Preferably, the control member 15 itself is movable up and down, and its lower edge is always held horizontally so that the distance from the top surface of the net conveyor 11 to the top surface of the net is adjusted.
The closer the distance between the lower edge of the control member 15 and the upper surface of the net of the net conveyor, the smaller the amount of small fish sent out per unit time.

The control member 15, which moves up and down to limit the amount of small fish sent out by the net conveyor 11, controls the amount of small fish placed on the net conveyor 11 using a fish sensor 16.
The fish sensor 16 controls the operation of the fish pump 9. The fish sensor 16 is connected to the net conveyor 1
When the amount of small fish above 1 falls below a predetermined value, a signal to operate the fish pump 9 is issued, and when the amount of small fish exceeds the predetermined value, a stop signal is issued to the fish pump 9.

The supply duct 6 is shown in FIGS. 3-4. This supply duct 6 sends small fish fed from the fish feeder 5 onto the steamer 17 together with dispersion water. This supply duct 6 includes an upwardly opening hopper 18 for receiving small fish sent from the fish feeder 5, and an expanding duct part that extends horizontally from the hopper 18 and becomes wider in the direction in which the small fish are transferred. 19, and a supply port 2 is provided downwardly at the end portion of the expanding duct portion 19 where the width is widened.
0 is open.

The supply duct 6 has a water supply port 21 opened on the opposite side of the expanding duct portion 19 so that the small fish are transported by being carried away by the dispersed water. The water supply port 21 is connected to the discharge side of a water pump 22, which is the water supply means 7, and the small fish are washed along the expansion duct portion 19 with dispersed water sent from the water supply port 21.

As shown in FIG. 4, the expansion duct portion 19 has side walls 23 on both sides and is open at the top.

The supply port 20 is opened downward, as shown in FIG. 3, so that the small fish placed on the steamer 17 are not swept along the steamer more than necessary by the dispersed water flowing out from the supply port 20. Furthermore, as shown in FIG. 4, the conveyor 8 has a wide shape in which its dimension in the width direction (vertical direction in FIG. 4) is larger than in the direction of movement of the conveyor 8 (lateral direction in FIG. 4). It is opened downward.

The water supply means 7 supplies dispersion water to the supply duct 6, loosens the small fish supplied in a lump, sends the small fish to the supply port 20 while uniformly distributing the small fish in the expanding duct part 19, and The purpose is to cause the particles to fall smoothly and uniformly onto the steamer 17 and to distribute them uniformly on the steamer 17. Therefore, the most preferable position for the water supply means 7 to supply water to the supply duct 6 is near the hopper 18 of the supply duct 6 and on the opposite side of the expanding duct section 19, as shown in FIG. However, although not shown, the water supply means can also supply dispersed water from the expanding duct part of the supply duct to the preceding process or near the delivery part of the net conveyor that is the fish feeder.

The discharge amount of the water pump 22, which is the water supply means 7, is determined to be an amount that allows the small fish fed into the hopper 18 of the supply duct 6 to flow smoothly and to be uniformly distributed on the steamer 17.

The water pump 22 is operated even when the net conveyor 11 of the fish feeder is stopped.

The steamer 17 has a net 2 stretched over a rectangular frame 1, and small fish are uniformly placed on the steamer 17 while being transported by a conveyor 8.

The conveyor 8 in FIG. 3 is a rope conveyor in which a pulley 24 is driven by a motor, a rope 25 is hung on the pulley 24, and a steamer 17 placed on the rope 25 is moved.

A steamer sensor 26 is provided on the rope conveyor to detect the presence or absence of the steamer 17 below the supply port 20. The steamer sensor 26 controls the operation of the net conveyor 11 of the fish feeder 5.

The net conveyor 11 of the fish feeder is operated only when the steamer sensor 26 detects that there is a steamer below the supply port 20, and when there is no steamer 3 below the supply port 20, the net conveyor 11 is operated.
operation will be stopped. Even after the net conveyor 11 of the fish feeder stops operating, the small fish in the supply duct 6 are sent onto the steamer 3. That is,
There is a time delay between the operation of the net conveyor 11 and the feeding of small fish from the fish feeder 5. This time delay is corrected by the mounting position of the steamer sensor 26. To be more precise, the steamer sensor 26 is connected to the supply port 20
It is located at a position shifted to the left in FIG.

The most suitable shape for the steamer is used depending on the purpose. Therefore, the present invention does not limit the shape of the steamer.

The steamers can be stacked together as a single unit or lined up to dry.

The small fish are washed by the dispersion water when they are evenly placed on the steamer 17. When it is necessary to clean the scales attached to the small fish on the steamer 17, use the third
As shown in the figure and FIG. 5, a cleaning nozzle 30 that sprays cleaning water upward may be disposed below the steamer 17 on which small fish are placed.

The cleaning nozzle 30 cleans the scales adhering to the underside of the small fish and causes them to fall off.

The cleaning nozzle 30 is connected to a steamer 1 on which small fish are placed.
In order to spray cleaning water uniformly over the entire width of the container 7, the width is increased upward as shown in FIG.

The flow rate of the cleaning water sprayed by the cleaning nozzle 30 is preferably determined to such an extent that the small fish on the steamer 17 do not jump upwards.

Below the steamer 17 and below the supply port 20,
A drain receiver 31 is provided to receive the dispersed water flowing down through the steamer 17, and a drain port 32 is opened in the drain receiver 31.

[Operation] Hereinafter, the operation of the apparatus configured as described above for uniformly feeding small fish to the steamer will be explained in the order of each member.

The dispersed water that is continuously fed into the supply duct 6 from the water supply means 7 is uniformly expanded through the expanding duct portion 19 of the supply duct 6 in the direction indicated by the arrow in FIG. 4, and is dropped from the supply port 20. .

In this state, when the steamer sensor 26 detects the steamer 17 being sent on the rope conveyor that is the conveyor 8, the web conveyor 11
is operated for a certain period of time, the small fish are supplied to the supply duct 6, are uniformly expanded together with water in the expansion duct part 19, and are dropped from the supply port 20.

In this case, the position of the steamer sensor 26 is determined by the time when the steamer 17 is detected in front of the supply port 20, the net conveyor 11 is started, and the small fish are carried to the supply port 20 by running water, and the time when the steamer 17 is detected in front of the supply port 20.
It is necessary to match the timing of the time when the water reaches the supply port 20. Therefore, the timing of stopping the net conveyor 11 must be determined before the steamer 17 passes through the supply port 20.

Since the water velocity in the expansion duct section 19 is constant,
It is expanded very nicely and filled into steamer basket 17.

The thickness of the layer of small fish filled on the bamboo steamer 17 can be adjusted by moving the control member 15 up and down, but it is also possible by adjusting the rotation speed of the net conveyor 11.

Scales on small fish such as sardines are washed and separated by running water and fall into the steamer 17, and the small fish remain on the mesh of the steamer 17, but the scales flow together with water into the drainage receiver 31 through the mesh of the steamer. Drain port 3
It is discharged from 2.

It is preferable that the amount of water dispersed in the expanding duct portion 19 is larger than the amount of small fish to be supplied. According to the inventor's experiments, filling a ¹ m square steamer with approximately 3 kg of sardines requires several hundred per minute to 1 m ³ per minute, and the water pump requires a diagonal flow or axial flow pump with a diameter of 80 to 100 mm. A low-head, high-flow pump such as the above was suitable, and the feed rate of the steamer was 30 pieces/minute, and the ratio of 30 pieces x 3 kg = 90 kg of sardines to 500 to 1000 pieces of water. The weight ratio of dispersed water to small fish was 18 to 9%. If the flow rate of the dispersed water is small, the water surface level in the supply duct 6 will drop, and small fish will not flow smoothly through the expansion duct section 19.

The layer thickness of small fish filled on the steamer 17 is:
This can also be done by adjusting the running speed of the rope conveyor as a variable speed, and the amount of small fish to be filled in one bamboo steamer can be adjusted depending on the size of the fish and the type of fish.

If the control member 15 of the net conveyor 11 is lowered too much when the fish is large, the fish may become clogged and cannot be discharged smoothly. Therefore, in this case, rather than lowering the control member, the net conveyor 1
It is better to lower the rotation speed of step 1.

Some of the small fish supplied to the steamer 17 have scales and the like attached to the back side thereof. The scales can be removed by blowing up a water stream from the bottom to the top with a cleaning nozzle 30 that matches the width of the steamer. As shown in FIG. 3, the cleaning nozzle 30 is preferably inclined in a direction midway between the traveling direction of the steamer 3 and the vertical direction. This is because vertically upwards, the last small fish in the bamboo steamer may spill in the opposite direction of the steamer's progress.

The rope conveyor has a load that is sufficient to support and transport the weight of the steamer 17 and small fish, so compared to the width of the steamer 17 and small fish, four ropes with a diameter of 10 mm are used. The washing water from the rope is thin and coarse, so it does not get in the way of washing the steamer.

Groundwater, seawater, etc. are supplied to the supply port 21 of the supply duct 6, but when drying immediately at low temperatures using cold air drying, etc., cold water is used, and the cold water is filtered to remove foreign substances such as scales. remove it,
It is best to recirculate and use repeatedly.

[Effect] In the present invention, a supply means for mixing water and small fish and supplying small fish intermittently at a uniform speed is disposed above the conveyor, and a flexible wire such as a rope is placed below the supply means. A plurality of conveyors are connected in an endless ring shape and extend horizontally, and a steamer with a porous net material stretched inside the frame is placed on this conveyor.
When the steamer is moving from one end of the conveyor to the other end, a signal from a detection sensor detects the approach of the steamer, and the small fish are evenly supplied from the supply port onto the steamer by the supply means along with water to evenly level the fish. It is configured to do so.

When this device drops a small fish containing a large amount of water onto a moving cellar from an upper feed port, the large amount of water will be sucked into the numerous openings in the porous mesh material of the cellar. In addition, it is perfectly leveled in the plane direction without scattering on the steamer, and is supplied in a uniform layer thickness. To explain the above action in more detail, a large amount of water and small fish are fed through the supply port, which is wider in the direction perpendicular to the direction of conveyor movement, that is, in the horizontal direction, than in the vertical direction. When water is supplied, small fish are momentarily suspended in the water by a large amount of water on top of the steamer, and the water flows down through the openings of the porous mesh material of the steamer, but the small fish are suspended by the small fish. Water does not flow into the previously closed opening, but instead moves towards the unblocked opening, and along with the water, small fish move towards that opening and block it. Therefore, small fish are carried along with the water from the thicker layer to the thinner layer,
The thickness of the layer of small fish on the steamer becomes uniform (similar to the principle of paper making). As the steamer moves by the conveyor, it is fed from one end of the steamer through a wide supply port in a wide, linear manner in the width direction, and is supplied as a surface in the direction of travel of the conveyor as well as the direction of travel of the steamer.

Furthermore, the water that passes between the small fish and the porous mesh material of the steamer has the effect of washing the small fish, and the small fish are not only uniformly dispersed by the water but also washed. The small fish on the steamer are then thoroughly cleaned and arranged evenly on the steamer.

Furthermore, the conveyor for transporting the steamer has a plurality of flexible wires stretched on the same plane, and the steamer is placed on the wires and transported. For this reason, the conveyor does not impede water permeation through the steamer,
Water permeates uniformly throughout the porous net material, and uneven distribution of small fish caused by uneven water permeation can be minimized.
This is because, as mentioned earlier, the device of the present invention allows water to pass through the part of the bamboo steamer that is not blocked by small fish, thereby allowing water to pass through the part of the bamboo steamer that is not blocked by small fish. Small fish are carried to areas with few fish and distributed evenly, but even though there are no small fish, if the bottom of the netting material or the conveyor is blocked and the amount of permeation water decreases, small fish will be present in these areas. Small fish are not transported sufficiently and are distributed unevenly, but the wire rod has a small contact area with the bottom surface of the net material, which reduces the area where small fish are supplied and reduces the uneven distribution area of small fish. Features can be realized.

Furthermore, small fish have soft bodies and easily get injured on their abdomens, but since they are fed together with water into the steamer from the feed port at a low head, uniform feeding can be achieved without damaging the small fish.
