Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for uniformly arranging small fish mainly on a porous sheet member such as a seimu or a net conhair.

A. Prior art The process of processing small fish, such as boiling, drying dried sardines, whitebait chirimen, etc., and drying, etc., and supplying the small fish uniformly and thinly to a net conveyor, etc. is often carried out. It will be done.

As shown in Figure 1, Sei μ is made of square wood, etc.
A rectangular frame 1 is made, and a sheet-like net 2 is stretched on 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 ten or more pieces of Sai μ3 on the assembly stand as shown in Figure 2, and heat them once in a boiling pot. The boiled material is spread out again one by one and dried in the sun, or transferred to a drying duct to dry. In addition, small fish may be supplied to an endless net conveyor made of a porous sheet member without using a seal.

At present, feeding the small fish to the tray or net conveyor in a uniformly thin form is generally done almost manually at present.

Figure 2 shows the process of manually leveling the small fish on the tray. First, a fish μ3 is placed on the solo pan chute 4, and a required amount of small fish from a fish tank is scooped up with a net and fed onto the fish μ3. Holding this Sei μ3 in your hand, tilt it up and down and diagonally using the water surface of the cleaning tank as a boundary, and move it down several times to even out the small fish. This work involves cleaning and leveling the small fish evenly, but it requires considerable skill to level the small fish evenly and evenly, and usually two people work in pairs, facing each other. It had the disadvantage of being labor intensive and time consuming.

B. Purpose The present invention has a structure in which 1. small fish are evenly spread on a porous sheet member and can be washed in this process, so that the small fish are uniformly spread without any spots, and does not require manual labor. To provide a device for uniformly feeding small fish to a porous sheet member, which can be efficiently arranged with accuracy.

C1 configuration Embodiments of the present invention will be described below based on the drawings.

The apparatus shown in FIG. 3 that uniformly supplies small fish to a porous sheet member includes a supply means 5 for supplying a fixed amount of small fish per unit time, and a supply means 5 for supplying small fish in a fixed amount per unit time, and a supply means 5 for supplying small fish sent by this supply means 5 together with dispersion water. A supply duct 6 for sending out and a water supply means 7 for supplying dispersed water to the supply duct 6. ! 1: A moving means 8 is provided for moving a porous sheet member 17 that receives small fish and dispersed water sent out from the supply duct 6.

The supply means 5 includes a fish pump 9, a sorter 10 that sorts small fish transferred together with water from the fish tank by the fish pump 9 and separates them from the water, and a sorter 10 that is delivered below the sorter 10. and a net conveyor 11 for transporting small fish in fixed amounts.

The sorting machine 10 uses grid materials 12U and 12D for sorting large and small fish.
The net conveyor 11 is strung with a double slope, and the small fish pass through the upper grid 12U, slide on the first grid 12D, and reach the net conveyor 11.
be dropped above. Large fish do not pass through the upper grid,
The upper grid 12U is removed. Upper and lower grids 12U, 12
A tank 13 is provided below D to remove water flowing down through the grids 12U and 120.

A drainage tank 14 is provided below the net conveyor 11, and water flowing down from the net conveyor 11 flows into the drainage tank 1.
Removed from 4. The net conveyor 11 is operated in synchronization with the movement of the perforated sheet member. Small squares are delivered to the supply duct 6 only when the net conveyor 11 is operated. If the operating speed of the net conveyor 11 is increased, the amount of small fish sent out will increase. In order to more accurately quantify the amount of small fish sent out by the net conveyor 11 during the potential time,
As shown in FIG. 3, a control member 15 is disposed above the net of the net conveyor 11. The control member 15 is preferably movable downward by itself, its lower edge is always held horizontally, and the distance from the top surface of the net conveyor 11 is adjusted. The closer the distance between the lower edge of the control member 15 and the net surface of the net conveyor, the smaller the amount of small fish sent out per unit time.

The control member 15 moves up and down to limit the amount of small fish sent out by the net conveyor 11. The control member 15 detects the amount of small fish placed on the net conveyor 11 with a type sensor 16, and uses this angle sensor 16 to control the fish pump. Controls the operation of 9. The type sensor 16 outputs a signal to operate the square pump 9 when the amount of small fish on the net conveyor 11 becomes less than a predetermined value, and outputs a stop signal to the fish pump 9 when the amount of small fish becomes more than a predetermined value.

The supply duct 6 is shown in FIGS. 3-5.

This supply duct 6 sends the small fish sent from the supply means 5 to the porous sheet member 17 together with dispersed water.

The supply duct 6 includes an upper-opening hopper 18 for receiving small fish sent from the supply means 5, and an expanding duct portion 19 that extends horizontally from the hopper 18 and becomes wider in the direction in which the small fish are transferred. A supply port 20 is opened downward at the end portion of the expanding duct portion 19 where the width thereof is widened.

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 angle is transferred by being carried away by the dispersion water. The water supply port 21Vi is connected to the discharge side of the water pump 22, which is the water supply means 7, and the small fish are washed along the expansion duct 19 with dispersed water sent from the water supply port 21Vi.

As shown in FIG. 5, the expansion duct portion 19 has side walls 2 on both sides.
3 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 porous sheet member 17 are not swept along the porous sheet member more than necessary by the dispersed water flowing out from the supply port 20. ing.

The water supply means 7 supplies dispersion water to the supply duct 6 and distributes the small fish uniformly in the expanding duct part 19 while supplying water to the supply port 20.
Moving on, the small fish are allowed to fall smoothly and uniformly onto the porous sheet member 17, and the porous sheet member 17-h is
This is for cleaning the small horns sent to the area from above. Therefore, the most preferable position for the water supply means 7 to supply water to the supply duct 6 is as shown in FIGS. 4 and 5.
This is near the hopper 18 and on the opposite side of the expansion duct section 19.

However, although not shown, the water supply member 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 serving as the supply means.

The discharge volume 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 transferred, and to wash the small fish on the porous sheet member 17. .

The water pump 22 is operated even when the net conveyor serving as the supply means is stopped.

The steamer 3, which is a porous sheet portion 817, has a rectangular frame 1 and a mesh 2 stretched over it.
The small fish are placed evenly while being transported.

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

A steamer sensor 26 is provided on the lobe conveyor 2 to detect the presence or absence of the steamer 3 below the supply port 20. The steamer sensor 26 controls the operation of the net conveyor 11 of the supply means 5.

Only when the steamer sensor 26 detects that there is a steamer below the supply port 20, the net conveyor 1 of the supply means is activated.
1 is operated, and when there is no steamer 3 below the supply port 20, the operation of the net conveyor 11 is stopped. Even after the net conveyor 11 serving as the supply means stops operating, the small fish that were 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 the small fish by the supply means 5. This time delay is corrected by the mounting position of the steamer sensor 26. Seiro sensor 2
6 is precisely located at a position moved to the left in FIG. 3 from the supply port 20.

A porous sheet member having an optimal shape is used depending on the purpose. Therefore, the present invention does not limit the shape of the porous sheet member.

If the perforated sheet members are steamers, they can be stacked as a single unit or dried side by side. When treating small fish continuously, the porous sheet member is formed into an endless belt shape. This porous sheet member is shown in FIG.

In FIG. 5, the perforated sheet member 17 is an endless perforated sheet-like belt 29, and the transport means is comprised of a roller 27 that drives the belt 29 and a motor 28 that drives this roller 27.

The total length of the belt 29 is determined to be a length that allows the small fish placed on the rack to be dried while being transported.
Small fish are evenly distributed on top.

The small fish are washed when they are uniformly placed on the porous sheet member 17 by the dispersion water. When it is necessary to wash the scales attached to the small fish on the porous sheet member 1γ, as shown in FIGS. The cleaning nozzle 30 that sprays the water may be disposed at a different location.

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 widened in width toward the nigga, as shown in FIG. 6, so that the cleaning water can be sprayed uniformly over the entire width of the multi-face sheet member 17 on which the small fish are placed.

The flow rate of the cleaning water jetted by the cleaning nozzle 30 is preferably determined to such an extent that small fish on the porous sheet portion side 17'' will not fly upward.

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

D. Operation The operation of the apparatus configured as described above for uniformly feeding small fish to the porous sheet member will be described in the order of each member.

(The dispersed water continuously fed into the supply tally 6 from the water supply means 7 is uniformly expanded in the direction of the arrow through the expanding duct portion 19 of the supply duct 6 and dropped from the supply port 20.

■ In this state, when the steamer 3 sent on the rope conveyor which is the transfer means 8 is detected by the steamer sensor 26, the net container 11 is operated for a fixed period of time, and the small fish are supplied to the supply duct 6. It is uniformly expanded together with water in the expansion duct section 19 and dropped from the supply port 20.

■ In this case, the position @ of the steamer sensor 26 is the time when the steamer 3 is detected at the hand m1 of the supply port 20, 711 is activated to the net controller, and the small fish are brought to the supply ["20] by running water, and the time when the steamer It is necessary to match the timing of the time at which the liquids reach the supply port 20. Therefore, the timing for stopping the net conversion hair 11 is also supplied by Seiro 3.
must stop before passing.

(2) Since the flow rate of the expanding duct 19 is constant, the water is expanded very efficiently and filled into the steamer 3.

■ The thickness of the layer of small fish filled in the steamer 31 can also be adjusted by moving the control member 15 up and down.
This is also possible by adjusting the rotation speed of the net conveyor 110.

■ Scales on small fish such as sardines are washed and separated by running water and fall into the steamer 3 and the small fish remain on the mesh of the steamer 3, but the scales flow together with water into the drainage receiver 31 through the mesh of the steamer and are drained. It is discharged from the port 32.

■ The amount of water dispersed in the expansion duct section 19 is much larger than the amount of small fish to be supplied. In the sound experiment of the present invention, 1 m'
It takes several hundred 17 sardines to fill a corner bamboo steamer with about 3 kg of sardines.
It takes 57 minutes to 1 m, and the water pump has a diameter of 80 mm.
~100mm diagonal flow or axial flow pump with low head and large flow rate is suitable, and the feeding speed of the steamer is 30 sheets in 7 minutes, and for 30 sheets x 3 kg = 90 kg of sardines, 50
The water ratio was 0-1000B. 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 level in the supply duct 6 will drop, and small fish will not flow smoothly through the expanding duct section 19.

■ The thickness of the layer of small fish filled in the bamboo steamer 3 can also be adjusted by making the traveling speed of the lobe conveyor variable. is adjusted.

■ When the fish is large, if the uniform member 15 of the net container 11 is lowered too much, the fish may become clogged and cannot be ejected smoothly. Therefore, in this case, it is better to lower the rotational speed of the net converter 11 than to lower the control member.

[Phase] Some of the small fish fed to the steamer 3 have some scales on the back side. From the perspective 1. The scales can be removed by blowing up a stream of water from the 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 vertically upward 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 load of the lobed conveyor is to support and transport the weight of 3 steamers and small fish, so compared to the 1000mm width of the steamer, it uses 4 lobes with a diameter of 10, and its cross section is shown in Figure 6. The cleaning water from the cleaning nozzle 30 is thin and coarse, so it does not interfere with cleaning the steamer.

■ Groundwater, seawater, etc. is supplied to the water supply port 21 of the supply duct 6, or cold water is used when drying and processing at low temperatures immediately using cold air drying, etc., and the cold water is filtered to remove foreign substances such as scales. It is best to remove it by eg, circulate it again and use it repeatedly.

E. Effect In the apparatus for uniformly feeding small fish to a porous sheet member of the present invention configured as described above, the feeding means feeds small fish to the supply duct, and the expanding duct portion of the supply duct supplies the small fish to the porous sheet member. Because it is configured to disperse small fish over a width of
The small fish are evenly placed on the porous sheet member with an even thickness, and the dispersed water not only places the small fish evenly on the porous sheet member but also prevents the small fish from being placed on the porous sheet member or during the transfer process. The small corners on the porous sheet member are arranged on the porous sheet part side 4- in a well-cleaned state.

That is, the present invention does not directly supply the small fish that can be sent out from the supply means to the porous sheet member, but instead interposes a supply duct in the middle, and furthermore, the small fish is evenly dispersed and cleaned,
To achieve an excellent effect in which small fish can be uniformly and thoroughly cleaned and arranged accurately, extremely efficiently and quickly on a porous sheet member.
