Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to fish whose ribs are embedded in the abdomen close to the outer skin, particularly catfish species (Ictalur fish).
Punatatus), comprising: a tool for separating the abdominal and dorsal fillets from the abdominal and dorsal spokes, respectively; a guide part that contacts the abdominal fillet cut and the back fillet cut, respectively, to guide the column; a pair of scraping tools for scraping the fillet pieces from the ribs; and opposing supports arranged with a gap and capable of being elastically biased. means and a conveyor for conveying the fish along the processing tools, each tool of the pair comprising a shaving knife disposed in front of a guide contacting the back fillet cut. It is related to the manufacturing equipment.

[Prior art]

A scraping tool is disclosed in German Patent No. 1,457,089. The trimming tool constitutes the last tool in a series of filleting tools in a fish filleting device. In this device, the counter-support means are provided with a toroidal edge, the counter-support means are fixed to the guide part in contact with the abdominal fillet cut, and the shaving knives are provided with a torus-shaped edge. The trimming knife is provided so as to leave a gap between the part and the support means, and the scraping knife is elastically bent laterally to the guide parts into which the back cut is inserted, and is assembled with these guide parts.

German Patent No. 2,946,042 discloses another shaving tool having a shaving knife which, when in the operative position, is associated with a guide which inserts into a previously made back fillet cut.

Adopted in both of these scraping tools,
The effectiveness of the principle of shaving off ribs to separate the fillet from the ribs in a cost-effective and economical manner is often recognized, but the shaving principle is often used when processing fish in which the ribs are embedded in the abdominal meat close to the outer skin. Using this principle, the meat on the underside of the ribs becomes the remaining part of the skeleton.

[Summary of the invention]

It is therefore an object of the present invention to eliminate said losses in the processing of valuable fish meat suitable for human consumption.

According to the invention, a tool is provided for separating the fillets from the ventral spokes and the dorsal spokes, and for guiding said fish laterally;
and a guide portion that contacts the separated abdominal fillet and back fillet in order to guide the pillar at a uniform height, a pair of shaving tools for shaving off the fillet from the ribs, and a gap. an elastically biasable opposing support means arranged to leave the
conveying means for conveying the fish along the tools, each said shaving tool comprising a shaving knife disposed in front of one said guide means contacting said back fillet cut; The cutting edge of the dropping knife extends away from the guide part, and the pair of knives of each scraping tool are arranged in a vertical relationship with each other so as to be σ-aligned with each other, and leave a gap therebetween, A device can be provided having cutting edges positioned in plan view facing each other;
This achieves the above objective.

The advantages obtained in this way are that the abdominal meat is stripped from both sides of the ribs, i.e. the ribs are effectively separated from the abdominal meat with only a small loss of fillet meat.

The arrangement of the trimming tools is such that an upper knife is associated with the guide part contacting the back fillet cut, a lower knife is associated with the guide part contacting the abdominal fillet cut,
Advantageously, the cutting edges of the cutting knives which are placed one above the other are associated with a common opposing support means. Moreover, it is possible to improve and reconfigure such equipment for fish filleting without affecting the basic design concept, thereby reducing the economic become suitable for processing.

The throughput of fish fillets can be further increased if the scraping knives, which are arranged one above the other, are configured to curve elastically away from each other at least in the region of the cutting edge means.

〔Example〕

Hereinafter, the present invention will be described in detail with reference to the drawings.

A pair of guide parts are arranged at the upper and lower parts of a guide path 1 (FIG. 1) for the fish 1T provided inside a machine for making fish fillets. These guide parts are composed of a back guide part 2 and an abdominal guide part 3. a pair of abdominal cutting round blades 4 are disposed coplanarly with the abdominal guide section upstream of the abdominal guide section 3;
A pair of back cutting circular blades 5 are arranged coplanarly on the back guide 2 upstream of the back guide 2. The back cutting round blade 5 is mounted on a vibrating crank 6 so as to be movable back and forth within the plane of the back guide. A push saddle conveyor 7 with push saddles 8 is provided as a conveyor for fish 17. These bush saddles 8 receive the fish 1T so that its abdominal cavity 18 straddles the saddles, and push the fish along the guide path 1 with its tail first. A pair of shaving tools or cutting tools 9 for performing rib cutting are provided downstream of the back cutting round blade 5 when viewed in the direction of transporting the fish. As shown in FIG.
It has a value of 0.11. Those scraping knives 10.11
are arranged one above the other with a gap 12 in between.

Each of the upper shaving knives 10 is associated with a respective one of the dorsal guides 2, and each of the lower shaving knives 11 is associated with a respective one of the abdominal guides 3, each extending in the same way. The cutting knife 10.11 is provided with wedge-shaped cutting edges 13 located on mutually facing sides. A common opposing support 14 with an annular cross-section is arranged facing both cutting edges of each scraping tool 9 with a gap therebetween. Each opposing support part 14 has a cutting surface of the abdomen cutting round blade 4 and a back cutting round blade 5.
It has a tip 15 which is pivotally mounted substantially parallel to the cut plane of the fish and is bent downward so that the end faces in the direction in which the fish is moved. Each opposing support 14 is held in a buffer or stop by the force of a spring 16 so that the tip 15 is located below the horizontal plane of the guide path 1. - Next, the operation of this device will be explained.

The fish 1T whose abdominal cavity has been opened and its internal organs removed is placed with its abdominal cavity 18 on top of the bush saddle 8 with its tail pointing in the moving direction of the conveyor.

Bush saddle 8 is advanced by bush saddle conveyor 7. After being aligned by alignment means (not shown), the fish 17 is advanced to the abdominal cutting knife 4 and the dorsal cutting knife 5. those knives 4,5
Make two cuts on each side of the ventral and dorsal spokes, respectively. The back cutting knife 5 is controlled via a cam 22 fixed to the bush saddle 8 so that the fillet is completely separated from the skeleton up to the tail area.

And in the region of the abdominal cavity, the cut is made along the upper part of the ribs. As the fish 17 is advanced further, the dorsal guide 2 and the abdominal guide 3 enter the corresponding above-mentioned cuts, thereby sandwiching the piece of meat containing the dorsal spokes 20 and the abdominal spokes therebetween. Guide part 2 of them in the state
．． 3 guides the fish. The lateral columnar appendages 21 and ribs 19 present in the region of the abdominal cavity 18 are guided in the lateral gap between the abdominal guide 3 and the dorsal guide 20. In this way, 17 fish and a pair of scraping tools, 9 tons.
The fillets are separated from the ribs 19. This operation is carried out in such a way that the ribs 19 move through the tip 15 and over the countersupport 14 . Immediately thereafter, the upper shaving knife 10 enters the cut made by the back cutting knife 5, and the lower shaving knife 11 moves under the ribs 19. It is preferable that the tip portion 15 of the support portion 14 has a lubricant-like structure. The cutting edge 13 of the scraping knife 10.11 is connected to the guide part 2.
3, the meat adhering to both sides of the ribs is scraped off, and due to the pressure applied to the underside of the ribs 19 or due to the springs 16, the opposing supports 14 straighten.
