While relatively moving the fish meat lump and the scraping blade along the longitudinal direction of the fish meat lump, the scraping blade is made to act so as to enter the blood and meat part of the fish meat lump, and vibration is applied to the scraping blade. This method is characterized by scraping the blood and meat from the fish meat chunks.

In addition to the above-mentioned requirements, the second invention of the present application, the method for removing blood and meat from fish meat, is characterized in that, in addition to the above-mentioned requirements, the scraping blade has a structure in which a plurality of relatively narrow single blades are arranged side by side. It is something.

Furthermore, the third invention, a method for removing blood and meat from fish meat, is based on fT.
This method is characterized by making a plurality of incisions in the blood and meat part in the longitudinal direction of the fish meat lump before applying the scraping blade.

Furthermore, the fourth invention, a method for removing blood and meat from fish meat, involves measuring the external shape of each fish meat lump to determine the individual blood and meat distribution situation obtained by converting the blood and meat distribution situation proportional to the external size into data in advance. According to this data, the working condition of the scraping blade is set according to this data.

Furthermore, the fifth invention of the present application, the fish meat blood and meat removal device, includes a transfer device that holds and transfers the fish meat lump in a constant posture, and a transfer device that is provided so as to be able to protrude from the transfer surface toward the fish meat lump side. It is equipped with a scraping blade or the like made up of a plurality of single blades arranged in parallel, and the scraping blade is characterized in that it operates in a vibrating state by a vibrating device.

Furthermore, a sixth invention of the present application, a fish meat removing device, is characterized in that, in addition to the requirements of the fifth invention, a plurality of disk-shaped slitters are provided at the front stage of the scraping blade. It is what it is.

At this time, the meat parts other than the blood-combined meat are not adversely affected to deteriorate the quality.

In addition, in the case of a single blade made up of many scraping blades tied together in parallel, scraping is performed according to the distribution condition (distribution depth) of the blood and meat.

Furthermore, when making cuts along the longitudinal direction of the fish meat chunks in the blood-combined portion before the scraping blade acts, this cuts the fibers of the blood-combined portion and makes the removal of the blood-combined portion by the scraping blade much smoother. done to.

Furthermore, by calculating the individual blood-meat distribution situation obtained by converting the blood-meat distribution situation proportional to the external dimensions of the fish meat mass into data in advance, it is possible to adjust the blood-meat distribution situation by simply measuring the external dimensions of the fish meat mass. Set the operating status of the scraping blade.

<Example> The present invention will be specifically explained below based on the illustrated example. In this explanation, first, the specific structure of the fish meat removing device according to the present invention will be described, and then its operating state will be explained. At the same time, the method according to the present application will be explained.

Reference numeral 1 denotes a blood and meat removal device, which is constructed by assembling various devices for the transfer system of fish meat chunks A and various devices for removing the blood and meat a into a frame 2 that is combined into a three-dimensional frame shape, as an example. It is.

First, regarding the transfer device 10, a table 11 is set up at a height suitable for an operator to handle the fish meat chunks in a standing position, and this table 11 serves as a support surface for the fish meat chunks A. Of course, fish meat chunk A has moisture or meat juice attached to it.
In addition, since the working environment requires cleaning and there is a lot of moisture, it is desirable to use stainless steel materials, etc., which do not corrode under such conditions, for the table 11 and other devices described below. As an example, a four-striped conveyor 12 with claws is provided along its longitudinal direction.

This conveyor 12 with claws also has a characteristic configuration, and this conveyor 12 has claws 14 for each chain link plate in a driving chain 13 whose conveyance track is partially set along the surface immediately below the table 11. equipped slat 1
5 is attached so that it stands up at a right angle. Therefore, the table 11 has a structure in which a long groove is cut out at a position where the claw conveyor 12 runs.

Of course, if the table 11 is not composed of a single flat metal plate, a flat member with a constant width may be provided on the action portion side of the claw conveyor I2.

In addition, as in the case of the conveyor with claws 12, the table 11 is provided with appropriate cuts or window-like holes in the parts where the various blood and meat removal systems described later act.
The driving chain 13 of the conveyor with claws 12 is provided with three strips,
Of these, the two on both sides have rectangular orbits set by turn sprockets 16 so as to roughly follow the shape of the frame 2, but the single drive chain 13 that supports the central two-strip conveyor 12 is driven by a drive motor M. Due to the position, the driving sprocket 17 is installed so that its running trajectory is somewhat different from that of the other driving chains 13 on both sides. Incidentally, all three drive chinos 13 are configured to be driven by the drive motor M by sharing a part of the shaft of the turn sprocket of the central drive chino 13. In addition, the slats 15 in the conveyor with claws 12 are provided only on the inner chain link plates of the drive chains 13 provided on both sides, and the slats 15 are provided on some both sides of the chain link plate of the drive chain 13 in the center. It is configured to provide. As a result, four pieces of fish meat can be processed on the table 11 at once. Of course, this design takes into account the work efficiency, and the number of conveyance tracks can be set appropriately depending on the work situation.

Furthermore, in order to assist in the transfer of the fish meat chunks A by such a driving chain 13, a pressing arm 20 is provided at a portion facing each claw conveyor 12. This is rotatably mounted on the table 11 at the base 20a, and pressed by the arm 2.
The tip end side of the conveyor 12 is always biased towards the claw 14 side of the claw conveyor 12 by the action of the spring 20b. As can be understood from this, as shown in FIG.
While being pressed against the table 11, it is transferred so as to slide on the table 11. Furthermore, the subsequent stage Sunawa chicken blood meat a
At the position where the scraping action is performed, pressing springs 21 are arranged in multiple stages so that more appropriate pressing can be performed according to the curved external shape of the fish meat chunk A. This is because one end of the pressing ring 21 is held by a spring holder 22, and each spring is configured to be biased toward the claw 14 side of the claw conveyor 12. As a result, the fish meat chunks A are pushed toward the claw conveyor 12 in several steps vertically from the surface of the table 11. In addition, in this part, an upper pushing roller 23 acts to press down the fish meat mass A conveyed from above, and this roller has its base rotatably held in the upper part of the frame 2. It is attached to the tip of the roller arm 24 and holds the fish meat mass A by its own weight.

Next, the blood and meat removal path device will be explained. code 3
0 is a scraping blade 30 which is the main member that performs the action of removing blood and meat;
1 are installed in parallel. Specifically, about 20 scraping blades each having a width of about 10 millimeters are provided for each conveyance line. This single blade 31 has a cutting edge 31a whose tip is directed toward the fed fish meat mass A, and has a dovetail 31b formed on its back side. This single blade 31 is made to be able to slide freely on a blade holder 32, and the blade holder 32 supports the single blades 31 in an aligned state with a front support plate 32a, and each blade is provided with a dovetail groove 32b. The dovetail ridge 31b of the single blade 31 is held. This blade holder 32 is fixed to the frame 2 via a clamp plate 33 with a bolt 34. Next, referring to the members of the shift system of this scraping blade 30, the reference numeral 35 is attached to the frame 2. A shift motor 36 is attached to each single blade 31 to the attached shifter holder. This shift motor 36 is used to drive a screw shaft mechanism and set the protruding state of its output portion. First, a slide rod 37 is directly connected to this shift motor 36. And this slide rod 37 is a relay rod 38
It is connected to the lower end portion of the single blade 31 via. As a result, the shift motors 36 receive electrical signals to move the single blade 31 up and down, and in this embodiment, the upwardly protruding state is set. Further, reference numeral 39 is a vibration generating device, which is attached to the blade holder 32 and acts to vibrate the blade holder 32 together. Specifically, for example, an air motor that generates rotation using compressed air is built in, and the eccentric shaft is rotated by the air motor, so that the stroke at the cutting edge 31a of the single blade 31 generates minute vibrations of about 0.5 mm.

Furthermore, in order to ensure the removal of the blood and meat by the scraping blade 30, a slitter 40 is provided which makes a slit in the longitudinal direction of the blood and meat a of the fish meat lump A at the stage before the scraping blade 30 acts.
will be established. This device is disk-shaped and includes a large number of slitters attached to its support shaft 41.

It is more preferable that the plurality of slitter 40 be provided along the boundary position of each single blade 31, and this slitter 40 has a support shaft 41 supported on a slitter support plate 42, is rotatably supported by the frame 2 at the base 43 on the other end side. The slitter support plate 42 is the slitter 4
A drive motor M2 is supported on the surface opposite to that supporting the slitter 0, and rotation is transmitted from the output shaft of the drive motor M2 to the support shaft 41 of the slitter via a drive chino 44. The slitter support plate 42 is provided so as to be movable around the base 43, and a shift cam 46 acts on the lower surface of this plate to set the position of the slitter support plate 42.
0 from the table 11 is adjusted.

That is, the shift cam 46 attached to the frame 2 is connected to the output shaft of the motor M3 via the chino 47, and sets the position of the shift cam 46 according to the rotation of the motor M3, thereby setting the protruding state of the slitter 40. . ′
Furthermore, below the scraping blade 30 is the removed blood meat a.
A collection chute 50 is provided, and a collection conveyor 51 is further run below the chute 50. Also, to describe the control system etc. that performs the indexing of the distribution of blood meat a according to the shape of the fish meat mass, etc., first, reference numeral 55 is a measurement sensor 55 installed near the starting end of the transfer device IO. - Using a photoelectric sensor as an example.

Of course, other suitable shape detection devices such as an infrared shower may be applied. Further, a start button 56 is provided on the frame 2 near the starting end side of the transfer device 1O, a control panel 57 is provided near and above the start button 56, and a control unit 58 whose main component is a switchboard is provided near the device side.

The blood and meat removing device of the present invention has the specific structure as described above, and operates as follows to remove the blood and meat.First, the operator removes the fish meat mass A that is supplied. Table 1 which is part of the transport device IO by hand
I'll put it on 1. At this time, in this embodiment, as an example, four-shaped conveyor 12 with claws is running, so four conveyors 12 are conveyed at once.
Processing of the fish meat chunk A can be done. Of course, when doing it manually, it is not possible to place four pieces of fish meat A on the table 11 at once when the work is done sequentially by people.
In any case, the work efficiency is better than when removing one tree at a time. Of course, any suitable work format may be employed, such as having two workers for each machine or mechanizing this supply work. Then, when loading the fish meat mass A onto this table ll, the worker transfers the fish meat mass A to the conveyor
2 to the claw 14 side. When pressing in this way, the claw 14 bites into one of the flattened cut surfaces of the fish meat chunk A, thereby moving the fish meat chunk A toward the scraping blade 30fI4.
Of course, this pressing is done during the transfer by arm 2.
0 and pressure are maintained by the spring 21. Immediately after the vehicle starts running, its outer dimensions, thickness, etc. are measured by the dimension measurement sensor 55.

This measured value is compared with the distribution of blood and meat that has been converted into data in advance, and the data is output from the control unit 58 as a control value for the shift motor 36 of each single blade 31. And scraping blade 30
The fish meat mass A that is being transferred towards the slitter 40
By passing through the fish meat chunk A, a plurality of incisions can be made along the longitudinal direction of the fish meat chunk A in the blood meat portion A.

Incidentally, this incision is made in order to cut the fibrous material in the blood meat a, and thereby the scraping by the scraping blade 3G described below can be smoothly performed.

At this time, since the distribution of the blood and meat a is known in advance from the data from the size measurement sensor 55, the output of the control unit 58 drives the motor M3, rotates the shift cam 46, and supports the slitter 40 as appropriate. The cutting depth of the slitter 40 can be set by changing the pushing up state of the support plate 42. Specifically, the distribution of the blood-combined meat a is relatively thick from the head to the center of the fish meat mass A, so the slitter 40 is sufficiently protruded in that area, and the blood-combined meat a is further extended toward the tail. Since the thickness of a decreases, the slitter 40 is retracted accordingly. After being processed in this manner, the fish meat chunks A are subsequently transferred and subjected to the action of a scraping blade 30. The scraping blade 30 cuts the blood and meat a determined in advance by the size measurement sensor 55.
The protrusion state is adjusted by the shift motor 36 according to the distribution of the blades, and the protrusion height is also set to gradually change for each single blade 31. The scraping blade 30 causes the entire blade holder 32 to undergo minute, relatively high-frequency vibrations under the action of the vibrating device 39, so that the single blade 31 scrapes off the blood and meat a or the meat portion a. The scraping action of the blood meat a is performed without excessive contact with the blood meat a, and since the scraped blood meat a is cut in the longitudinal direction by the slitter 40, it has a narrow band shape or falls into a string-like state from the lower surface of the cutting edge 31a of the single blade 31 into the collection chute 50 and is removed by the collection conveyor 51.

(Effects of the Invention) The present invention has the configuration described above, and the scraping blade acts according to the distribution of blood and meat, and the cutting edge vibrates minutely when the scraping blade is activated. Because of this, even if the knife penetrates into a chunk of fish meat, there is no excessive contact between the cutting edge and the chunk of fish meat, making it possible to smoothly scrape off the blood joint.

Furthermore, if the scraping blade 30 for removing the blood and meat is a combination of multiple single blades 31, the blood and meat a.
The operating position of each single blade can be adjusted according to the distribution of the meat in the butcher section a. It becomes possible to remove the blood and meat a without wasting it.

Furthermore, when making cuts in the longitudinal direction of the blood meat a before scraping it off with the scraping blade 30, the fibers in the blood meat a are divided in advance, so even when the scraping blade 30 acts Blood and meat a can be smoothly removed.

Furthermore, blood meat A according to the size of fish meat lump A in advance
By converting the distribution situation into data, it is possible to infer the distribution situation of the blood meat a by simply measuring the external dimensions of the supplied fish meat chunk A, and the operating situation of the scraping blade 30 can be set accordingly. Therefore, it is possible to more accurately remove the blood and meat a according to the distribution situation.
