Description

[Detailed description of the invention] (Field of industrial application) The present invention is a fish head cutting machine used in the fish processing industry. This makes it possible to separate the entrails.

(Prior art) Traditionally, when a fish processor removes the head and guts of a mackerel, they use a knife to make an incision in the abdomen of the fish, then hold the head and body of the fish and remove the fish. The head and gut were removed at the same time by pulling.

Recently, a fish head cutting device (Utility Model Publication No. 60-784) has been developed, including a cutter installed near the end of the endless conveyor path, and a fish body tightening device whose side plate collapses to tighten the fish body when it passes a predetermined position. A group of fish head holders on which fish heads are placed, which are fixed horizontally on a conveyor side by side with the fish body holders, with a gap that allows a cutter to be inserted between the group and the fish body holders, and a head holder. There is a type of push-in tool that is driven to push the fish into the fish body fastener side and position the fish's fish bone in the cutter part.

(Problem that the invention aims to solve) However, when cutting the fish head by hand using the knife described above, when cutting off the head, the head is forcibly pulled and removed, so the hook on the body side is removed. This caused the problem that the fish meat on the body side was reduced by about 3% and the yield was extremely poor because the part was torn off and attached to the unnecessary head side.

In addition, when cutting, a great deal of force is applied to the fingertips, so if your fingers get tired and you have to remove a large amount of fish heads, your work efficiency will decrease as the work time progresses, which will interfere with your daily work. Since it requires a large number of workers, there are problems in that the labor costs are high and it is not possible to effectively cut the fish head.

Furthermore, in the above-mentioned fish head cutting device, even if the fish head can be cut, it is not possible to remove the entrails connected to the fish head at the same time as cutting off the fish head. Moreover, this type of cutting device uses complicated fish body fasteners, fish head pressers, etc., which makes the entire device expensive.

The present invention was developed in order to solve the above-mentioned conventional problems, and uses blades placed at a predetermined distance and guides on both the left and right sides to cut off the fish head and remove the entrails at the same time. The purpose is to provide cutting machines.

(Means for Solving the Problems) The fish head cutting machine according to the present invention is provided on the left, right and lower sides as shown in FIGS. 1 to 4 of the drawings of the embodiment. Cutlery 1, 2 separated by a gap S, 7' of a size commensurate with the dimension a,
3, a left guide 22 consisting of a vertical guide part 23 and a horizontal guide part 24 that regulate the cutting depth of the right cutter 1 and the lower cutter 3, and a left guide 22 that regulates the cutting depth of the right cutter 2 and It is composed of a right side guide 26 having a guide part 27 for regulating the cutting depth at the rear part and a guide part 29 for separating the fish head 10.

(Function) When simultaneously removing the head 10 and guts 9 from the fish 8 such as mackerel using the fish head cutting machine of the present invention having the above configuration, hold the body of the fish 8 so that the abdominal side of the fish is facing down. Then, pass the head 10 side of the fish body 8 from above to the bottom through the gap S between the left and right blades 1 and 2 rotating between the left and right guides 22 and 26. A diagonal cut along the gills and a cut on the ventral side of the fish head 10 are made with the lower cutter 3, and the fish held in the hand is laterally cut by the regulation of the guide and the rotation of the cutters 1, 2, and 3. You will be guided to the right side knife 2.
through the gap S' between the lower cutter 3 and the right guide 2.
While regulating the cutting depth by the guide part 27 of 6, the head and body are cut with the lower part of the rotating right cutter 2, and in this state, the fish body 8 is twisted diagonally, and at the same time, the fish body 8 is pulled and cut into the right side guide. Break the fish skull using another guide part 29 of 26, and insert the fish head 10 from the body.
However, at this time, there is no cut in the gut 9, so when the fish head 10 is cut off, the gut 9 is also removed.

(Example) Next, an example of the present invention will be described based on FIGS. 1 to 4 of the drawings.

In the figure, 1, 2, and 3 are a pair of left and right blades supported by shafts 5, 6, and 7 on the machine base 4, and the blades installed at the bottom of the blades.

The separation of 0 is carried out continuously in a fish processing factory. When cutting the heads of mackerel using the traditional manual method described above, one worker would weigh 800 kg per day.
The fish head cutting machine of the present invention can process 1,300 kg per fish head, and if the above-mentioned worker performs the process day after day, fatigue accumulates and the throughput decreases, resulting in a significant drop in efficiency. In machines, high efficiency can be constantly increased without any changes.

(Effects of the invention) As described above, the fish head cutting machine of the present invention uses the left and right lower cutters and the guides on both the left and right sides to cut around the gills of the fish head, but does not cut into the guts of the fish body. Therefore, since the structure is such that the guts can be removed at the same time as the head of the fish is cut off, unlike the traditional method of making an incision with a knife and forcibly pulling the head to remove it, it is easier to remove the fish head. Since the part is attached to the body side and the fish meat on the body side that becomes the product does not decrease, the yield can be improved, and the shape of the cut in the body after cutting the fish head is also good. . Furthermore, even if the fish head is removed continuously, the work efficiency does not decrease, so it is possible to improve efficiency and greatly reduce labor costs due to the labor saving of the workers, allowing for effective fish head cutting. At the same time, it also cuts off the fish head and removes the guts at the same time, making it possible to cut the fish head with higher efficiency compared to conventional equipment.It also has a unique structure that can be manufactured at low cost because it uses a simple blade and guide. This is effective.
