Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for taking out boiled small fish in a continuous boiling device for small fish.

The present inventor has so far developed several continuous boiling devices for small fish. One such device is a continuous boiling device that has already become known in Japanese Patent Publication No. 51-33993.In this device, a boiling liquid medium forms a circulating flow path for the liquid medium in a fixed direction in the boiling tank. , small fish are thrown into the appropriate place in this channel and boiled while flowing through the channel. Even a take-out device consisted of a screen belt conveyor that was sunk inward and raised at the end to lead out of the boiling tank, and was scooped up onto a continuous screen belt and taken out.

Therefore, small fish taken out by such a take-out device are transported from the end of the screen belt conveyor of the take-out device into a drying room if the fish are small, such as Chilimenjako. The small fish are then fed by falling onto a mesh belt conveyor that is guided by the mesh belt conveyor, and the small fish are dried by passing the mesh belt conveyor around the drying chamber. In the case of large pieces like dried sardines, it takes more than a day and night to dry them, so they are also dropped onto a bamboo steamer, etc., and the small fish that are spread out on the bamboo steamer are placed in multiple tiers. The method used is to place it on a frame-equipped cart, send it to a drying chamber, and leave it there for about a day and night to dry it.

In this way, if the boiled small fish is large, it needs to be placed on the bamboo steamer and dried for a long time. In the case of relatively large fish such as dried sardines, when the fish is dropped from the above-mentioned take-out device onto the bamboo steamer, the impact of the fall may cause breakage or other damage to the fish. There was a problem that I thought was easy to accept. Therefore, with this extraction method, there was a problem in that it was not possible to obtain high-quality products from small fish such as dried sardines, which had relatively large bodies.

In view of the above-mentioned circumstances, this invention provides a new taking-out device that can continuously take out relatively large small fish that have been continuously boiled in a boiling tank as described above onto a bamboo steamer without damaging them. This is what we are trying to provide.

That is, the take-out device of the present invention inserts the steamer into the flow path of the boiling liquid medium of the boiling device having the circulation flow path of the boiling liquid medium from the small fish-free zone downstream in the flow direction. Then, in the upper boiled zone where small fish exist, a rectangular steamer with a width approximately equal to the channel width of the zone is placed.
The boiled small fish can be directly scooped onto the bamboo steamer by lifting it out of the flow path. In this way, small fish that are boiled while flowing through the flow channel will be scooped onto the bamboo steamer at the position where it was boiled, and taken out of the bamboo steamer as it is. If the wax is directly sent to the drying room, the small fish scooped onto the bamboo dryer will be dried without being subjected to any shock, resulting in a product of very high quality.

In addition, small fish that are thrown into the circulating flow path of such a boiling liquid medium and boiled while flowing along the flow path with the liquid medium float near the surface of the liquid medium when boiled and fill the entire width of the flow path. Since the flow is almost uniformly distributed, the steamer can be inserted into the flow path from the lower end of the flow path, that is, from the lower end of the area where the small fish that have already been boiled have been scooped up by the steamer. hand,
If you sink it to the bottom of the tank and pull it out of the tank at the leading edge of the stream of boiled small fish, it will be evenly distributed over the entire width of the stream. The small fish that are scattered and floating in the water are taken out as they are evenly distributed and placed.

That is, the take-out device according to the present invention is suspended between a pair of sprocket wheels that are mounted on the outside of the tank and a pair of sprocket wheels that are mounted on the shaft inside the tank, so as to open the flow path. A pair of parallel endless chains are inserted with their tip sides inclined from the outside of the tank at the bottom in the flow direction of the liquid medium to the liquid medium in the tank at the top in the flow direction, and the running path of this chain is inserted into the appropriate place. A guide rail is inserted from the outside of the tank into the tank along the same line with its tip side inclined, and is equipped with a point switching device at the turning point of the tip, and a trochanter whose tip side is pivoted on the tip side. A large number of steamer retaining frames are supported on the guide rail and whose rear end sides are pivotally connected to the endless chain at equal intervals, and are driven to circulate together with the chain without rotating, and in the flow path of the endless chain. and a chain driving means for driving the upper side of the tank in the upward direction, and when the bamboo steamer is supplied onto each of the holding frames outside the tank, it passes through the tank and directs the flow of boiled small fish. The gist is that the container is configured so that it can be taken out of the upper tank that it crosses.

Next, examples will be given, and the take-out device of the present invention will be described.

The swing rails 20c are connected to each other so as to be able to move toward and away from each other, and this swing rail 20c also constitutes a point switching device for a trochanter 24, which will be described later.

And a pair of endless chains 18 as described above
A plurality of bamboo steamer holding frames 23, 23, which are pivotally mounted 22 at appropriate positions on the rear end sides of both sides at equal intervals, and are swingably connected at the front ends thereof, are provided.
Via the trochanter 24 that is pivoted on both sides of the tip side,
The tip side of the guide rails 20a, 20b on both sides
is supported on the steamer holding frame 20c, and when the chain 18 is driven in the direction of the arrow B, the trochanter 24 is guided on the lower guide rail 20a and the steamer holding frames 23, 23... 1 into the tank 1 from outside, and when the pivot portion 22 to the chain 18 rotates around the sprocket wheel 13, the trochanter 24 pushed forward and downward moves against the swing rail 20.
c to the position shown by the chain line in Figure 3, and then ride on the swing rail 20c as shown by the solid line in Figure 3.
The steamer holding frame 23 is forced to make a U-turn, but at this time the steamer holding frame 23 is attached to the pivot portion 2 to the chain 18
Even if 2 makes a U turn, the trochanter 24 is only guided onto the upper guide rail 20b without reversing (rotating).
The upper end of 0b is curved downward, and this tank 1
At the outer fold, when the pivot 22 of the steamer retaining frame 23 to the chain 18 rotates around the sprocket wheel 16, the trochanter 24 is attached to the rail 20.
Then, the rotor 24 passes through the gap α between the rails 20a and 20b, and even here, even if the chain 18 makes a U-turn, the steamer holding frame 23 does not reverse ( The trochanter 24 is guided in the direction of arrow B on the guide rail 20a without rotating.

The details of this bamboo steamer holding frame 23 are as follows.
As shown in Figure 4, the rectangular bamboo steamer 25 can be placed on top of it to fill its width W, and 23a, 23a, 23a are designed so that the bamboo steamer 25 can be placed on top of them. The frame portions 23b and 23b are the frame portions 23b and 23b that fit together both outer surfaces of the bamboo steamer 25 to regulate its width direction.
c is a stopper for engaging the front end of the steamer 25 in the feeding direction into the tank 1 to lock and hold the steamer 25 in a fixed position on the steamer mounting frame 23; 10, the steamer 25 is moved onto each steamer retaining frame 23 at position C outside the tank 1 by artificial means from the rear upper side (top right in FIG. 3). Or send it using mechanical means and hold it in the steamer holding frame 23.
When the bamboo steamer 25 is allowed to collide with the upper stopper 23c placed upward, the steamer 25 is held on the steamer retainer frame 23 and flows into the tank 1 at the lower end of the flow path 3 at the B position. small fish-free zone)
After entering the liquid medium, the pivot portion 22 of the steamer holding frame 23 passes around the sprocket wheel 13, and its trochanter 24 moves under the rail 20c that constitutes the point device. After passing through and making a U-turn on top of it without rotating, the steamer 25 remains on the holding frame 23 at the top (small fish presence zone) of the channel 3 at position B. It is to be pulled up from the liquid medium in the tank 1 to the outside of the tank 1 and diagonally upward.

Therefore, in the take-out device of the present invention configured as described above, when the steamer 25 is pulled up from the liquid medium in the flow path 3 in an upwardly oblique direction, While flowing along with the liquid medium in the channel 3 onto the wax 25, the boiled small fish are scooped up and taken out of the tank.

In the figure, 26 indicates B of the flow path 3 in order to smoothly guide and scoop up small fish that have flowed through the flow path 3 to the position of the extraction device 10 onto the net of the bamboo steamer 25. At this point, an inclined guide plate is installed in the flow path 3 diagonally upward from the bottom of the tank 1 to cover the upper part of the trajectory of the steamer 25 in the liquid medium to a certain height, and to control the flow inside the flow path 3. The small fish that have arrived are guided near the water surface by this inclined guide plate 26. 27 is this guide board 26
A rubber plate 28 has its proximal edge 27a fixed to the distal end of the rubber plate 28, and its distal edge 27b elastically contacts the upper surface of the bamboo steamer 25. and its proximal edge 28a
is fixed, and its tip edge 28b is brought into contact with the upper surface of both sides of the steamer 25 under the rubber plate 27, and the rubber plate cover is used to cover the upper side, and the water flows through the flow path 3 to this position B. The small fish in the liquid medium that has been boiled during this time is reliably guided only to the upper surface of the bamboo steamer 25 by the rubber plate 27 and the rubber plate cover 28, and is scooped up thereon. There is.

In addition, the width of the channel 3 is enlarged in the section B of the channel 3 of the boiling tank 1 in which the tip side of such a small fish extraction device is submerged, compared to the boiling process section D above it. A portion E between the portion D and the portion B is formed in a shape that widens toward the end, and the small fish that have flowed through the channel 3 are allowed to flow in the stream that is wider in this portion B than in the portion D. Spread across the width of Road 3,
It is starting to be scooped up to the top of Seiro 25.

In addition, in the B portion of the flow path 3, a suction port is opened at least at a width wider than the width W of the bamboo steamer 25 at the lower part of the tip side of the take-out device 10 submerged in the liquid medium. A box-shaped suction duct 30 having an opening 29 is fixedly disposed on the bearing frame 11, and the discharge opening of the duct 30 is adjusted to a window hole 31 formed in the partition wall 2,
It is connected to the suction side of the pump device 4.

In this way, the boiling liquid medium flowing through the B portion of the channel 3 passes through the entire width of the steamer 25 moving in the upward direction, and is circulated in the direction of the arrow A. However, in this embodiment, the suction port 29 of the duct 30 is divided into several parts in the width direction of the flow path 3, and each of the divided suction port parts 29a, 29
In a......, adjustment plates 32, 32......, which can adjust the opening amount thereof, can be slid through bolts 33 and elongated holes 34 provided in a bracket protruding from the lower surface of the suction duct 30. It is provided. That is, by appropriately adjusting the opening amount of each suction port portion 29a divided by each adjustment plate 32, the flow rate of the liquid medium sucked into the pump device 4 from the suction port 9 can be adjusted to the flow path 3. As a result, the liquid medium flowing through the D section of the channel 3 spreads uniformly in the E section, and small fish are uniformly distributed in the width direction in the B section. It is becoming possible to do so. However, in other embodiments, the suction port 2 of the suction duct 30
The opening amount of the suction port 9 may be adjusted in advance as described above. Of course, the design can be changed arbitrarily.

In addition, in the figure, 35 is a shaft rack 36 on the bearing plate 11.
Reference numeral 37 is a presser roll disposed opposite to the presser roll, and the presser roll 37 is pivotally supported 40 by the free ends of a pair of arms 39 whose base ends are swingably supported 38. At the same time, a stopper 41 is provided opposite to the arm 39. 42 is a steamer 25 that is sent out backwards (to the upper right in Figure 3) by the delivery roll 35 and the presser roll 37.
This is a conveyor for receiving and conveying further to the rear.

As is clear from the detailed description of the embodiments, the device for taking out small fish according to the present invention enters the flow path of the boiling tank from the lower side in the flow direction of the liquid medium to the upper side in the flow direction. Using a holding frame for the steamer, which is configured to circulate upward in the flow direction without rotating obliquely upward, the steamer is supplied and placed on top of it outside the tank. Then, the steamer is automatically fed into the tank in the zone where small fish are not present, and when it reaches the bottom of the tank, it is made to make a U-turn without reversing (rotating), and the flow path in the boiling tank is While crossing the flow of small fish that were boiled while flowing through the water, the small fish that had been boiled were pulled up diagonally backward and upwards while crossing the stream, and at that time, the small fish that had been boiled were scooped up onto the bamboo steamer and taken out of the tank. Since it can be taken out extremely smoothly, according to the device of the present invention, the bamboo steamer taken out of the tank in this way is carried as it is to the drying room, and the small fish on it are directly removed. If the amount of small fish flowing through the channel is made uniform, it is natural that the boiled small fish flowing over the bamboo steamer will spread over the entire width of the channel. This means that the water is evenly dispersed and scooped up, and in particular, as mentioned above, the width of the flow path at the part where the bamboo steamer is pulled out of the tank is expanded, and the water is spread to fill the entire width of the expanded flow path. If the structure is such that the liquid medium flows uniformly through the bamboo steamer, small fish can be scooped up onto a wide bamboo steamer in a thinner and more uniform manner. In this respect, it is possible to obtain a product of better quality by shortening the time required for production.
