Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention is applicable to fish that has been cut into three pieces in advance, such as salmon,
This relates to a marine food processing machine that cuts the halves of trout, silver cod, etc. into predetermined sizes.

``Prior art'' Conventionally, when cutting fish into rings or squid-like thin slices (from salt to raw materials), a number of round blades were fixed to a shaft via spacers, and a flat plate or It can be cut straight by passing it through a rotating drum or the like.

However, if the half body of salmon, trout, etc. that has been grated into three pieces is cut straight, the width of the fillets will be smaller, and the product value will be lower than that of fillets cut diagonally.

Therefore, in the case of fish such as salmon and trout, it is common to cut the half body into three or two pieces diagonally with a knife to form fillets, which is inefficient and can be cut by eye. Because of this, there are often too many fillets or too little.

This human-force strategy poses problems for supermarkets and food processing plants that require large quantities of fillets, such as high labor costs.

In order to eliminate the above-mentioned human sea tactics, an automatic filleting machine (Japanese Patent Application Laid-open No. 49-30571) is known, but this automatic filleting machine uses an intermittent feeding mechanism of a rotating table and a complicated crank mechanism. It is extremely difficult to increase work efficiency because the feeding of the fish is stopped and the holding member is moved up and down each time the fish is cut.

"Problems to be Solved by the Invention" In order to solve the above-mentioned problems, the present invention aims to solve the above-mentioned problems by simply placing half pieces of salmon one after another on a moving plate, and the salmon is automatically formed into fillets. As long as it is formed in half, it is possible to process as many volumes as you like, making it possible to meet large-scale demand, and furthermore, through automation, it is possible to reduce labor costs all at once.

In addition, since the position of the cutter can be adjusted individually according to the size of each half of the salmon, it is possible to form the salmon to an approximate size (weight), which solves problems such as too much or too little of the product (fillet). Ru.

``Means for solving the problem'' (A) An endless chain is arranged on the left and right sprockets arranged at the front and rear of the aircraft body, and a large number of plates are arranged on the endless chain at arbitrary intervals.

(B) A guide member is disposed approximately at the center of the plate in the direction of movement so that the plate disposed on the endless chain is held horizontally.

(C) A plurality of cutting mechanisms are attached to the frame with respect to the plate held horizontally by the guide member.

(D) Each cutting mechanism shall have a gear motor and a cutter that rotates or stops depending on whether the gear motor is turned on or off, fixed to the tip via a shaft.

(E) Adjustment of the height of the cutter or its angle with respect to the plate, as well as its advancement and retreat, consists of screw shafts attached to the casing and threaded members that engage with these screw shafts.

(F) A pressing member provided with an endless belt that does not come into contact with the cutter and that restrains the workpiece on the plate is shifted at a required interval in the direction of movement of the workpiece. To be arranged.

The object of the present invention is to provide a marine food processing machine characterized by comprising each of the constituent elements (A), (B), (C), (D), (E), and (F).

``Function'' Position the cutting mechanism body by moving it forward or backward according to the thickness, width and length of the workpiece placed on the plate, and then adjust the cutter angle and vertical position relative to the workpiece. After adjustment, when the plate is driven, the workpiece on the plate moves forward while being pressed and restrained by the pressing member, and fillets of the required width are sequentially formed on the plate by the rotary cutter.

When the number of fillets reaches a predetermined number, for example 4, the position at which the workpiece is pressed shifts to the opposite side of the cutter side, and is pressed and restrained by the next-stage pressing member, and the rotary cutter cuts the number of fillets of the required width. or formed into a plate.

Since the present invention is configured as described above, by rotating the handle 481 according to the size of the workpiece cut into three pieces, the first side plates 37 and 38 are moved through the guide rollers 33 and 34. By moving forward while rolling on the guide rails 31 and 32, the cutter 11 is moved to a predetermined position.

Next, by rotating the handle 491 in accordance with the thickness of the fillet of the workpiece, the gear motor 12 and the second side plates 54, 55 move up and down using the shaft 61 as a fulcrum, and rise or fall to a predetermined position. Seshimuru.

Next, the cutting angle of the cutter 11 is adjusted by rotating the handle 561 relative to the workpiece.

When the machine is operated in this state, the plates 70, 70, . . . on the endless chain and the pressing member rotate at the same speed.

"Effects of the Invention" When the half piece 85, which has been cut into three pieces in advance, is placed horizontally on the running plate 70, the one piece 85 is pressed against the plate by the pressing member 78, and in this state, the plate The fillets are sequentially cut into predetermined dimensions by rotating cutters 11, 11, . . . to form fillets.

When the number of fillets reaches a predetermined number, for example, 4, the position of the belt of the pressing member that presses the workpiece is shifted to the opposite side from the one side of the cutter, so that the workpiece can be accurately pressed by the belt. The present invention has effects such as being pressed and restrained and being continuously cut as the plate moves forward.

In addition, the plate (cutting board) has an inclined V groove 7.
Since a large number of 01, 701... are formed, the back skin part of the fillet is also cut cleanly.

For example, since each piece of salmon cut into three pieces is approximately the same size, it is only necessary to adjust the position of the cutter once, and the rest is processed continuously, making it possible to meet large demand.
