Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for cutting a fish body into three pieces along the bones.

In the secondary fish grating device, the fish is sandwiched between conveyors on the left and right, and fed between a pair of circular saws or band mirrors whose spacing is matched to the thickness of the backbone.The circular saw or band saw cuts the meat on both sides of the backbone. Since the fish was cut into three pieces, it was impossible to control the direction of the fish and transport it so that the dorsal fin was parallel to the saw, so the fish was either in the state shown in Figure 13 or in the opposite state. The fish body is transported at an angle to the left and right, and the fish body is cut along the cutting lines A and B as shown by the chain lines in the figure, or the fish body is fed obliquely between the left and right conveyors as shown in Figure 14 of the figure. Alternatively, if the fish body is bent even if it is fed straight, the fish body will be cut as shown by the cut line and mouth, and the bone will be cut, so it is necessary to ensure that there are three pieces of the fish body. It is impossible to do this, requires rework after grating, and has the disadvantage of poor product quality yield.

In contrast, the fish body removal device according to the present invention includes a towing means for grasping the tail of the fish body and towing it in the axial direction, and a vibrating means provided in the path of the towed fish body so as to sandwich the spine of the fish body from both sides. A pair of pongee knives that give vibration in the longitudinal direction,
A guide for narrowing the blades so that only the blade part can be seen and guiding them so as not to cut into the spine, and opening the gap between the narrow blades so that they do not touch the towing means when they pass through the towing means, and immediately following the passing of the towing means. By providing an opening/closing means for closing the guide so that it comes into contact with the spine, the vibrating weaving knife can be guided to cut along the spine of the fish body, thereby solving the above-mentioned conventional drawbacks. be.

The other horizontal punch 24 is also rotated outward in the same way as the Fujimura 24 due to the meshing of the fan-shaped gears 34, 34, so that the fine blade supported by the horizontal punches 24, 24 can be rotated outwardly. 28 and 28 are spaced apart from each other so that the towing means can easily pass through, and the towing means A is passed through this interval. When the towing means A passes through, the large diameter portion of the cam 36 is immediately disengaged from the lever 35, so that the lever is closed. -35 is returned by the spring 37, rotates the Fujimuras 24, 24 inward, narrows the distance between the Tsumugi knives 28, 28 so as to sandwich the bone 3'' of the fish body 3, and the motor 44 The motor 29 rotates the head-cutting mirror 2 in a certain direction at high speed by rolling onto the shaft 42, and the motor 29 transmits power to the eccentric wheel shaft 30 to rotate a pair of eccentric spinal cords 31, 31 attached thereto in opposite phases. , 32, a pair of thin blades 28, 28
is vibrated at a high speed, so when the receiving member 55 of the fish body 3 is held on the conveyors 4, 4 in this operating state, when the fish body 3 is supplied with the tail 3' aligned with the positioning member 59, the conveyor 4 It reaches the position of the towing means A and the fish body 3 supported by the sending piece 5 attached to the feeder 5 and the support plate 9 of the chains 8, 8, and at this time the movable piece 14 of the towing means A is attached to the pond end of the horizontal shaft 13 attached. The rolling ball 17 at the bottom of one end of the lever 15 engages with the guide 21 and is pushed upward, so the movable teaching piece 14 descends and clamps the tail 3' of the fish 3 between it and the fixed clamping piece 12. .

At this time, the receiving member 55 descends below the conveyors 4, 4, and when the fish 3 is placed on the conveyors 4, 4, the feeding piece 5 supports the rear side of the fish 3, so that the fish 3 is attached to the towing means A. The feed piece 5 is sent to the head cutting saw 2, and the head is cut off by this saw 2. When the head of the fish body 3 is finished being cut off in this way, the trochanter 19 of the lever 18 attached to the lower end of the ratchet 11 with the towing means A attached to the support plate 9 is moved to the chain 8 which has been close to the head cutting saw 2. In order to shift from the nearby guide 20 to the opposite guide 22 closer to the chain 8, the lever I8 is rotated 90 degrees to change the direction of the towing means A, which had been facing sideways up until now, to the rear, and to move the fish body. 3 tail 3'. Pull it to move forward on the sliding plate 6. In this way, the fish body 3 becomes the Tsumugi knife 28, 2.
8, the Tsumugi knives 28, 28 open outward to avoid the towing means A, and when the towing means A passes between them,
The thin blades 28, 28 close immediately and pinch the rear end of the fish body 3, which has almost the same thickness as the bone 3'', immediately after the towing means A. In this case, they are guided as shown in Figure 11 of the drawings. 3
3, 33 hit the bone 3'' of the fish body 3 and slightly separate the liquid blades a, a of the Tsumugi knives 28, 28 from the bone 3'', so the Tsumugi knives 28, 28 do not work on the bone 3'', but the bone The meat is cut at the closest position of 3", but the cutting state is at guide 3.
3 and 33 are cut along the bone 3'' to guide the pongee blades 28 and 28, so curved fish bodies 3 are also cut along the curves, and any fish body 3 can be cut in two directions along the bone 3''. The so-called three-piece cutting process, in which the fish body 3 is cut into three parts, the central bone 3'' part and the meat parts on both sides, was automatically and accurately performed in a timely manner. In this device, a head-cutting device was attached to the fish-grating device, and the face-cutting and draining were performed in a series, but after the head-cutting device was separated and the head-cutting was performed, Of course, it is also possible to do it in the same way.

The fish body cutting device according to the present invention has the fish body being towed by the towing means with its tail held by the towing means. The fish is cut into three pieces automatically.

The guide guides the thin blade along the spine and makes a tracing cut along the spine, so if the fish body is curved, a curved three-piece cutter will be created, and the thin blade will be cut very close to the spine. Since the fish body is cut at certain positions, less meat remains attached to the backbone, which significantly improves the texture of the meat. The Tsumugi knife is vibrated in the longitudinal direction by a vibration means to push and pull the meat, so cutting is done smoothly and easily at high speed, and the cut surface is also good, improving the commercial value of the product.

The opening and closing means of the Tsumugi cutlery are interposed between each other, and the blades are opened so that they do not touch the towing means when passing through the towing means, and are closed so that the guide touches the spine after passing, so that the towing means and the fine cutlery can be separated. It is possible to reliably perform the three-fold operation along the spine without causing any interference. It has the following unique effects.
