Description

[Detailed description of the invention] (a) Industrial application field The invention relates to a quantitative feeding device for soft seafood such as raw fish, such as small fish for dried sardines, locusts, sardines, oysters, etc. This is a quantitative feeding device used in other seafood processing and packaging processes.

(b) Prior art As a fixed-quantity feeding device for fish for feed, there is a rotary type in which a rotary valve is installed in a valve chamber having a supply port at the top and a discharge port at the bottom, with a part cut out to form a fish storage space. Although there is a quantitative feeding device, the fish is severely cut and spoiled, and although it can be used for feed, it cannot be used for seafood as food as described above. Therefore, a flexible sheet with a smooth surface was bent and attached to the lower end of the supply port and the front end of the rotary valve.
It was proposed in Publication No. 41839, and a system in which the weight of fish fed into the weighing tank was weighed and the mechanism for supplying and discharging fish to the weighing tank was linked to this was proposed in 1983.
It was proposed in Publication No. 105133.

(c) Problems to be solved by the invention The invention described in the above-mentioned Publication of Utility Model Publication No. 48-41839 has the following problems:
When stopping fish from falling from above, the fish caught between the edge of the supply port in the direction of rotation and the rotary valve will not be cut due to the cushioning effect of the sheet, but the inner surface of the casing and the outer surface of the rotary valve will prevent the fish from being cut. There is a drawback that it may be damaged between the
The device described in Publication No. 105133 not only requires a lever-type weighing device, but also requires means for interlocking this weighing device with the fish feeding device and the fish discharging device, which has the disadvantage of making the structure complicated. Ta.

(d) Means for solving the problem In order to improve the above-mentioned drawbacks, the present invention creates a space for housing fish and shellfish by cutting out a part of the cylindrical valve chamber that has a supply port at the top and a discharge port at the bottom. In a rotary quantitative supply device equipped with a column-shaped rotary valve, the casing of the valve chamber located on the side in the direction of rotation of the rotary valve from the supply port is moved so that there is at least a gap between the inner surface of the casing and the rotation locus of the rotary valve. The rotary valve is configured to bulge from the supply port to the discharge port, and at least the supply port and the discharge port on the bulging side are provided with a flexible plate-shaped body that reaches the rotation locus of the rotary valve over the entire width of the rotary valve. It is characterized by:

(E) Effect Fish and shellfish that enter the fish and shellfish storage space of the rotary valve facing the supply port enter the bulge one by one, but the lower end of the bulge is blocked by a plate-like body, so the fish and shellfish are not accommodated. The fish and shellfish accumulate in the space and the bulge, and as the rotary valve rotates, the rear end of the fish and shellfish storage space reaches the plate-shaped body of the supply port, and then the entry of fish and shellfish stops, and the fish and shellfish continue to rotate until it reaches the front end of the fish and shellfish storage space. When the fish and shellfish pass through the plate-shaped body of the discharge port, the fish and shellfish fall from the discharge port, and a certain amount of the fish and shellfish accumulated in the fish and shellfish storage space and the bulge can be discharged downward. In this case, when closing the supply port, the rear end of the seafood storage space does not directly hit the casing of the valve chamber, but hits the flexible plate-like body, and the casing is bulged and there is nothing in front of the plate-like body. Since there are no obstacles, the plate-shaped bodies can easily bend in the direction of travel and escape, and the seafood will not be cut or damaged by being caught between them. In addition, when the rear end of the seafood storage space moves inside the bulge, there is a risk that it may damage the fish and shellfish filling that area, but small fish are in a fluid state, and large fish and shellfish are in a fluid state. If it is supplied with water, the fish and shellfish can easily escape, and according to this proposal, there is a gap between the rotation locus of the rotary valve and the casing, so there is no narrow part, so the fish cannot be bitten or crushed. There is no. Generally, fish and shellfish are transported together with water in order to improve fluidity and to prevent damage to the fish and shellfish, so there is no need to separately supply water.

(F) Example An example of the present invention will be explained with reference to the drawings.
In FIG. 1, 1 is a cylindrical valve chamber having a supply port 2 at the top and a discharge port 3 at the bottom, and within the valve chamber 1, a part is cut out to form a seafood storage space 4. A columnar rotary valve 5 is rotatably accommodated, and a casing 6 of the valve chamber 1 on the side in the direction of rotation of the rotary valve 5 indicated by an arrow in the figure is placed between the inner surface of the casing 6 and the rotation locus of the rotary valve 5. The bulge 7 has a gap D.
The other casing 8 is configured to follow the rotation locus of the rotary valve 5. Reference numeral 9 denotes a plate-like member attached to the inner surface of the supply port 2 on the bulging side with a restraining plate 10, and is provided over the entire width of the rotary valve 5 so that its tip reaches the rotation locus of the rotary valve 5.

Next, in the enlarged views of Figures 2 to 4, 11
is a plate-shaped body attached to the inner surface of the discharge port 3 on the bulging side with a restraining plate 12, and the leg 15 of the restraining plate 12 is engaged with a screw rod 14 screwed into a female screw 13 protruding from the casing 6. The tip of the plate-like body 11 is configured to be freely adjustable downward from the position where it reaches the rotation locus of the rotary valve 5, and is fixed with a screw 16 passing through the hole in the plate-like body 11 and the elongated hole of the casing 6. Depending on the size of the seafood that moves up and down the plate-shaped body 11 to provide a gap between the rotary valve 5 and the rotation locus,
Adjust the gap to make it larger for large seafood, and make it smaller for small seafood. If this gap is large relative to the fish body, more seafood will leak.
If it is small, it will cause more damage.

Next, regarding another embodiment shown in FIG. 5, different parts and power transmission parts from the previous embodiment will be explained. The rotary valve 5 of this embodiment has a screw rod 52 in which a right-hand screw and a left-hand screw are carved into an I-shaped rotary valve body 51.
and an adjustment plate 53 screwed to the screw rod 52.
Two seafood storage spaces 40, 40'
In addition, the gap D of the bulge 7 is made wider at the bottom than the top so that seafood can easily fall, and the supply on the side of the casing 8 opposite to the bulge 7 is made A plate member 9' is attached to the mouth 2, and the casing 8 side also bulges 7' to create a gap.
D' is allowed, and the processing of the casing 8 is omitted. As shown in FIG. 6, the rotary valve 5 is driven by a push plate 19 rotatably held at the tip of a lever 18 fixed to the power shaft of a rotary actuator 17 supported on the main body. The push plate 19 engages with a recess in the rotary plate 20 fixed to the rotary plate 20, and as the rotary actuator 17 rotates, the push plate 19 pushes the rotary plate 20 approximately.
Rotate it 180 degrees, prevent it from reversing with the stopper 21, and turn it around.
It rotates 180 degrees back and forth.

(g) Effects of the invention Since the present invention is constructed as described above, it is possible to supply a fixed amount of flexible seafood without cutting or damaging it, and it has an extremely simple structure and can be manufactured at low cost. In addition, a certain amount of seafood can be held not only within the rotary valve but also within the valve chamber, which has the effect of making the rotary valve smaller and, by extension, the machine smaller. .
