DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for automatically separating fish eggs wrapped in an epidermis into epidermis and fish eggs.

[0002]

2. Description of the Related Art Among fish eggs, one of the so-called high-grade fish eggs is salmon eggs, or salmon roe. Conventionally, in order to separate the fish egg from the epidermis, the fish egg with the epidermis is placed on a mesh having an appropriate size, and is manually performed by hand fir. The work requires considerable skill. Furthermore, in the case of hand fir, a part of the epidermis inevitably mixes with the fish egg separated through the mesh.

[0003] For this purpose, it is necessary to remove the contaminated epidermis from the fish eggs. For the separation, a large amount of water is consumed in a water tank type tank of about 350 liters to about 540 liters, which is called a stirrer, while stirring. We are working to separate the epidermis and fish eggs. As other examples, JP-A-7-274910 and JP-A-9-65859 are disclosed.

[0004]

However, in the conventional hand-fed type, manual work is performed while applying appropriate pressure so that the fish eggs are not crushed and the epidermis and the fish eggs are easily separated. It is extremely difficult to maintain this operation for a long time. Even though the work was done carefully at the start of the work, it takes a break, but for a long time throughout the day, it approaches the limit of physical strength, and the work tends to be complicated. In addition, it is very difficult to eliminate uniform products due to individual differences. In addition, because it is a hand-fir operation, it is necessary to knead the surface of the skin to separate the fish eggs. There is a disadvantage that a water tank type stirrer using a large amount of water is required for the separation.

Further, Japanese Patent Application Laid-Open No. 7-274910 discloses a streak connecting a fish egg and an epidermis by a parallel motion while applying an appropriate pressing force to the upper surface of the opened fish egg by applying vibration to a belt-shaped contact. The method and the device for cutting and separating the shape of the fish are to be applied.In order to use this method and the device, apply a moderate soft force to the fish egg, and do not damage the fish egg. Separation work is performed. However, even if it is a moderately soft force, skill is required for individual differences and the power to give, and not only can not produce a uniform product but also unnecessary vibrations to fish eggs will cause quality deterioration. .

[0006] Japanese Unexamined Patent Publication No. 9-65859 discloses a fish in which proteolytic enzyme is added and dissolved in a 1% saline solution tank, and fish eggs are reliably separated and separated in 5 to 11 minutes. Although the proteolytic enzyme attached to the egg is washed and removed, the proteolytic enzyme once attached to the fish egg causes a change in the fish egg, which leads to a deterioration in quality. . The present invention is directed to solving the above-mentioned conventional fish egg separation means, in which the raw material of the fish egg with the skin is fixed in a fixed position, and a certain amount is used without using any aqueous solution or chemical. It was developed with the objective of providing a device for separating fish eggs and epidermis into fish eggs and epidermis automatically and uniformly on the mesh while applying pressure without changing human hands. is there.

[0007]

According to the first aspect of the present invention, there is provided an apparatus comprising:
An automatic separating device for a fish egg in which a frame provided with a net is connected to the rocking device, and a pressing device for pressing a skin surface of the fish egg is provided on the upper surface side of the net, wherein at least a pressing body of the pressing device is provided. It is characterized in that one recess is provided. Further, in the apparatus according to claim 2, a frame provided with a net is connected to the swinging device, and a pressing device for pressing the skin surface of the fish egg is provided on the upper surface side of the net, and the lower surface on the opposite side across the net is provided. The present invention is characterized in that in an automatic fish egg separating apparatus provided with an elastic body for scraping fish egg grains, the elastic body is a separator provided with an elastic body, and the separator is provided on a main body.

[0008]

BEST MODE FOR CARRYING OUT THE INVENTION A fish egg wrapped in an epidermis is opened halfway by opening a pressing device, and placed on a rocking net with the epidermis facing upward, and then set on the upper surface of the epidermis. When a net is rocked while applying a pressure by a pressing device provided with a pressing material including the following, fish eggs are sequentially separated from the mesh of the net and fall naturally. However, the fish eggs that have come out of the epidermis, which are merely repeated as they are, sometimes hover under the net and do not fall naturally. In particular, since the last stage egg does not spontaneously separate, the last step is to scrape the fish egg from the other side across the net. And only the epidermis remains on the net. Moreover, there is no damage to the separated fish eggs. Further, in the case of setting a half-finished fish egg with a skin on a net, the separating effect can be further enhanced by setting the fish egg in a direction substantially perpendicular to the swinging direction of the net.

An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a cross-sectional view of a main part of the automatic separation device according to the embodiment as viewed from the side. The entire apparatus 10 of the present invention is divided into a separation device main body 1 and a driving device 2 for the separation device, and the space between them is connected by each connecting tool. In FIGS. 1 and 2, guide rails 3 for swinging the net 7 are provided on the separation device main body 1.
The net 7 is tensioned by a frame 6 provided with a roller 9 for swinging, and the frame 6 is connected to a lever 34 provided with a connecting pin 35 for swinging drive. On the upper surface of the separating device main body 1, at least one concave portion 28 is provided on the net 7 after the fish egg A with the skin opened in half is set on the net 7 with the skin 26 facing up. An openable pressing device 20 having a pressing body 22 is provided.

The pressing body 22 wraps the half open fish egg A on the net 7 so that the fish egg A with the skin does not move together with the net 7 even when the net 7 swings. The pressing device 20 is adapted to stay. Pressing device 20
A pin 48, a spring 47, and a nut 46 are provided at the center of the seat 21 of the pressing body 22 so that the pressing body 22 can easily contain the fish egg A with the skin and can be adjusted. is there. The pressing body 22 is provided on the seat 21 so that it can be easily replaced when worn.

Next, as shown in FIGS. 5 and 6, the fish egg A with the skin is connected to the skin 26, the streak 23, and the fish egg grain 25, respectively. As the net 7 swings, the skin 26 and the streak 23 of the fish egg 25 are cut off, and the fish egg 25 separates on the lower surface of the net 7 and falls naturally. However, in some cases, the skin 26 or the streaks 23 are stuck and do not fall.
Therefore, in order to scrape off the fish egg grains 25 suspended on the lower surface of the net 7, the apparatus is provided with a plurality of separators 17 shown in FIGS. 1, 3, 5 and 6. This separator 17 shown in FIG.
Has an elastic member 18, and an adjusting member 5 for adjusting the tension of the separating member 17 is provided on the other end side of the elastic member 18, and is provided at an arbitrary position of the separation device main body 1.

In the state shown in FIGS. 5 and 6,
When the raw material of the fish egg A with the skin is placed on the net 7 and pressed by the pressing body 22, the lower side of the net 7 is separated by the elasticity of the net 7.
7, the outer skin 26 and the stripes 23 are cut by swinging the net 7 to separate the fish egg grains 25. FIG. 5 shows a state in which the fish egg 25 has slipped out of the mesh 8 of the net 7, and FIG. 6 shows a state in which the slipped fish egg 25 has come into contact with the separator 17 due to the swinging of the net 7. Is shown. As a further feature of the separating body 17, when the separation of the fish egg grains 25 approaches the end, the fish egg grains 25 may be suspended by the epidermis, streaks, etc., and may not fall naturally. It is the plurality of separating bodies 17 that exerts its power in separating and dropping. A gap is provided between the lower part of the mesh 7 and the separator 17 to prevent the abrasion of the mesh 7 when the apparatus is adjusted without load when the elastic mesh 7 is used.

Further, since the separating body 17 has the elastic body 18, a soft contact action is exerted on the fish egg 25, so that the fish egg 25 is never damaged. In the fish egg A with the skin at the final stage of the completion of the separation, the skin 26, the streak 23 and some fish egg grains 25 remain on the net 7. Then, as shown in FIG. 4, the fish eggs 25 enter the concave portion 28 of the pressing body 22 and repeatedly oscillate in the forward and reverse directions with the swing of the net 7, while the fish egg 25 passes through the mesh 8 of the net 7 and is scraped by the separating body 17. Taken. Therefore, the skin and the streaks remain on the net 7. When the net 7 does not bend like a wire net, the separating member 17 may be configured so as to be in sliding contact with the lower portion of the net 7 from the beginning.

The mesh 7 having a punched-type mesh 8 made of metal, synthetic resin, or the like is more planar than the mesh 7 having an undulating knitted mesh 8 in a plane shape. It has a better effect on cutting at the time of separation, and has favorable effects such as easy cleaning after work. In the net 7 having the mesh 8 of the weaving method, the fish egg grains 25, the skin 26, the streaks 23 and the like are apt to adhere to the undulations, and the processing is somewhat troublesome. The separated and dropped fish eggs 25 are placed on the lower surface of the separating device main body 1 with a receiving pad 24 or, if a mass production line is desired, a plurality of the present devices are arranged and the pads 24 are removed to remove the space on the lower surface of the present device. Alternatively, a conveyor may be provided to collect the cargo.

Next, as shown in FIG. 1 and FIG. 2, the drive device 2 has a pin 33 provided on the shaft 29 of the drive motor 30 at a position eccentric from the axis of the motor 30. Crank pull
Re-31 is provided. On the other hand, a pin 35 is mounted on the frame 6, the pin 35 is connected to the lever 34, and the other end of the lever 34 is connected to the pin 33 to swing the net 7. . The drive device 2 is configured as described above, but is not limited thereto, and can be arbitrarily changed.

[0016]

As described above, according to the present invention, the fish egg covered with the epidermis of the raw material is opened to the half body, so that the fish egg grains are on the net side, and the epidermis is on the opposite side of the net. And put it on. Then, after setting the surface of the skin with a holding device that is flexible and has a certain amount of frictional force, the fish eggs are separated uniformly at any time without any human intervention. Thus, a good fish egg product without damage can be obtained. Moreover, since the epidermis does not mix with the fish egg grains, not only the conventional separation and stirring device for removing the epidermis becomes unnecessary, but also a large amount of water or chemicals is not used for the separation work. The result is a completely natural fish egg, with significant economic benefits. With this device, you only need to set the fish eggs with skin as the raw material, and after that, when the separation is completed, you only have to take out the fish eggs and the skin, so one operator can operate several of this device. It is possible to In addition, the degree of work fatigue can be reduced as much as possible without requiring the skill of the operator, which is useful for improving work efficiency in many cases.
