Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to a fish processing device, and in particular, to a fish processing device for treating fish with a large body shape.
This is characterized in that it is possible to always cut at an appropriate cylindrical location regardless of z.

(Prior art) When processing fish bodies such as tuna, bonito, or mackerel, first the head is removed, then the abdominal part is removed, the tail, dorsal fin, etc. This process adds the following processing.

Recently, fishing boats are equipped with refrigeration equipment.

Caught fish is immediately frozen on board the fishing boat, unloaded as-is, and then stored and distributed in a frozen state. It takes a considerable amount of time to thaw this fish, and once thawed, the quality of the fish deteriorates significantly if it is refrozen, so the above-mentioned removal of the head and abdominal cavity has traditionally been done by freezing the fish. Band saws and circular saws were often used for this work.
.

By the way, when performing the above-mentioned cutting operation, first a holding frame for the fish body is prepared and used to hold the fish body, but in all conventional devices, the shape and dimensions of the holding frame are fixed, and the fish body cannot be held in place. It was not possible to change this according to the size of the fish, so when processing fish of a constant size, when the size of the fish changes, the position to cut it would be inappropriate. A decline in the quality and yield of product fish was unavoidable. For this reason, there has been a desire to develop a device that has high work efficiency and can always cut at the appropriate location even if the size of the fish changes.

(Means for Solving the Problems) The present invention has been made in view of the above points, and includes several holding frames each consisting of a receiving frame and a presser frame, which are rotatably mounted on a workbench. Two circular saws are attached to the workbench, and the holding frame is raised and lowered in synchronization with the rotating movement of the holding frame, so that when it rises, it cuts the fish body into the receiving frame in an area where there is a gap between the holding frame and the holding frame. is set, the presser frame lowers, the head of the fish is cut and removed in the area that fixes the fish between it and the receiver frame, then the abdominal nest is cut and removed, and when the presser frame rises again, this The fish body is automatically taken out from the receiving frame, and in particular, the receiving frame changes its shape to match the body shape of the fish, so that the appropriate part of the fish body is always cut.

(Examples) Hereinafter, the present invention will be specifically described based on illustrated examples.

Reference numeral 1 in the figure is a workbench, and a rotary shaft 2 is erected in the center thereof, and several support arms 3 are radially attached to this. A holding frame 4 is rotatably attached to the tip of each support arm via a connector 5, and as the rotary shaft 2 rotates, the workbench
It is designed to rotate above.

To further explain the holding frame 4, this frame rotates on the workbench 1 while holding the fish body F, which is the material to be processed, and changes direction at a position where a circular saw 6, which will be described later, is provided to cut the fish body F. The head is made to protrude toward the circular saw, and consists of a receiving frame 7 on which the fish body F is placed, and a holding frame 8 that clamps the fish body F between the receiving frame 7 and fixes it. Of course, these can be replaced with appropriate ones depending on the body shape of the fish F to be processed; in other words, they can be attached to and detached from the support arm 3 at will. To explain this in more detail, a mounting plate 9 and a support plate lO are attached to the connector 5, and a sliding plate 1 is attached to the support plate lO.
1 is attached along the support plate so that it can be moved up and down. The receiving frame 7 is fixed to the mounting plate 9, and the holding frame 8 is fixed to the sliding plate 11. Needless to say, the sliding plate 11 is made to be able to rise and fall freely in order to allow the presser frame 8 to be moved up and down, and a hanging rail 12 is provided above the orbit of the sliding plate 11. On the other hand, a running shaft 19 is attached to the top of the sliding plate 11, so that the sliding plate 1 can rotate while being suspended from the hanging rail 12. Of course, the suspension rail 12 is at a high position from point D to point A shown in FIG. 8 is raised, and the fish body F can be newly set and the cut fish body can be taken out.

Further, a cam 14 is provided on the workbench 1, and
A roller 15 that engages with the mounting plate 9 is attached. These are for controlling the posture of the holding frame 4, and a coil spring 16 is stretched between one point of the mounting plate 9 and one point of the support arm 3, and is attached to the holding frame 4 in a counterclockwise direction in the figure. A force to rotate is applied, and this force causes the roller 15 to engage with the cam 14, and at point B, the front edge 7f of the receiving frame 7 is positioned at the outermost side of the rotating orbit, and at point 0, the front edge 7f of the receiving frame 7 is positioned at the outermost side of the rotating orbit. is located at the outermost position (
(See Figure 2), and the device main body constructed in this way is equipped with a circular saw 6 for cutting off the head of the fish body at 8 points in the figure, and a circular saw 17 for cutting off the abdominal nest at point 0. I am prepared.

Incidentally, the receiving frame 7 is formed to be slightly smaller than the length and width of the fish body F to be processed, and in particular, its upper surface is recessed to match the shape of the body of the fish body.
, the fish F is inevitably set in a predetermined position, the head and abdominal part of the fish F protrude from the front edge 7f and side edge 7s of the receiving frame 7, and the head is cut a by the circular saw 6. The abdominal cavity is cut along line b by a circular saw 17.

Of course, there are differences in the size of fish F.

When placing the fish F on this, the front edge 7a of the receiving frame 7 is used as a guide, the head is pushed out, and the position to be cut is aligned with the line a in the figure (the cutting line by the circular saw 6). However, in this way, although the head of the fish F can be cut at the desired position, the protrusion of the abdominal part from the side edge 7s differs depending on the size of the fish F, so the position to be cut is Since it does not match the b line, it is not possible to cut at the appropriate position.

Figure 3 deals with such a case, and the receiving frame 7
In addition, prepare one or more auxiliary receiving frames 72 and 73 that are suitable for smaller fish than the fish F that fits into the receiving frame 7, and use these auxiliary receiving frames according to the size of the fish to be processed. 7, and when the fish body F is placed on this, the predetermined position of the abdominal cavity matches line b,
The appearance of this is the receiving frame above.

That is, the auxiliary frame 72 has a lower surface that matches the four parts of the upper surface of the receiving frame 7 and is attached so as to overlap therewith, and its upper surface is formed to be slightly smaller than the upper surface of the receiving frame 7. When you set a fish that is slightly smaller than the one you are setting, the position where you want to cut its abdominal nest will match line b.

Similarly, the auxiliary receiving frame 73 is designed to hold smaller fish.

Reference numeral 18 is a locking pin. This thing is.

When the holding frame 8 is lowered and the fish body is held between it and the receiving frame 7, it is inserted into the fish body and securely fixed, so that the posture of the fish body does not change when cutting the head and abdominal part. It's something that does that.

It is installed in a position that will not affect the product.

In addition, when setting the fish body F in the receiving frame 7 (or auxiliary receiving frame), the front edge 7f of the receiving frame 7 (or auxiliary receiving frame) is used as a reference, and the position is determined using the fish carp as a guide. When the distance from the cutting line a of 6 is wide and positioning is difficult, a support guide 13 is attached to the front surface of the presser frame 8. Of course, this item is only used as a reference for positioning when setting the fish body, so there are no particular limitations on its shape or structure, and it should not interfere with setting or resetting the fish body. For example, a guide plate may be suspended from a pin.

(effect) When trying to process fish F, first.

The holding frame 4 is set to a predetermined size, and a drive motor (not shown) is driven to rotate the rotary shaft 2 and the holding frame 4 is rotated. Then, the fish F is set in the receiving frame 7 at point A.

When the holding frame 4 rotates past point A, the holding frame 8 descends to clamp and fix the fish F between it and the receiving frame 7.

When the holding frame 4 further approaches point B, it rotates counterclockwise, and the head of the fish F protrudes from the rotating orbit.
Next, it reaches point B and is cut by the circular saw 6. When the holding frame 4 exceeds point B, it rotates clockwise so that the abdominal cavity of the fish F is projected from the rotating orbit, reaches point 0, and is cut by the circular saw 17.

Then, when the holding frame 4 further turns and reaches point D, the presser frame 8
The fish body F with its head and abdominal cavity removed is removed from the receiving frame 7 by an unillustrated extraction guide, and the force holding frame 4 is rotated toward point A, and the same process is repeated. It is possible.

(Effects of the Invention) As detailed above, the present invention provides a rotating shaft in the center of the workbench 1, and radially attaches several support arms to the rotating shaft.
Furthermore, a holding frame consisting of a receiving frame and a holding frame is attached to the tip of the holding frame, and in particular, the holding frame is rotatably attached to the support arm, so that when the holding frame is rotated to a predetermined position, the head of the fish is fixed. In addition, the holding frame is suspended by a suspension rail provided at the top of the rotation track of the holding frame, and the mechanism is extremely complicated. It has the advantage of being simple, easy to work with, and highly efficient.

In addition, by superimposing an auxiliary receiving frame on the receiving frame, it is possible to treat fish with different body shapes, making it extremely versatile.
