Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for cutting a fish knot and a device therefor capable of keeping the width and the thickness constant and controlling the maximum length to be cut.

2. Description of the Related Art A method and an apparatus of this kind are disclosed in, for example, (1) JP-A-58-5.
No. 1095 and (2) Japanese Patent Laid-Open No. 58-77495. The former is to cut a fish segment by rotating a plurality of rotary blades with a plurality of cutting blades attached to the outer peripheral surface of a cylindrical base cylinder and slowly sliding the fish segment in a certain direction at a constant speed. . On the other hand, the latter is a rod-shaped, tubular, disk-shaped, etc. By abutting from one end of the direction in a substantially orthogonal shape, the fish knuckle is cut in a substantially orthogonal shape to obtain an elongated shaving knuckle having a width of several mm to tens of mm.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention In the one disclosed in the above-mentioned first publication, the number of feed rollers that slide the fish nodes that are brought into contact with the cutting blade is large, and the configuration thereof is complicated, and the cutting blade is It takes time and effort to adjust the mounting height positions of the multiple rotary blades with the attached. Moreover, since the sliding of the fish pieces between the rotary blades must be performed slowly and at a constant speed, the cutting efficiency of the fish pieces cannot be improved.

Further, in the one disclosed in the above-mentioned second publication, the position at which the cutting blade is provided is limited to the end face of the base material such as a rod shape, a cylindrical shape, or a disc shape, so that the position in the radial direction of the base material is different. In addition to the change in the shape and size of the fish pieces cut by the cutting blades, the obtained cut pieces were limited to those that were substantially orthogonal to the longitudinal direction of the fish pieces.

Means for Solving the Problems In the present invention, in order to solve the above-mentioned problems, in the first method invention, the supplied fish knots are sandwiched and moved to a fixed position in the fish knot supplying direction, and the fish is kept in that state. Cutting a certain length of the fish knot while rotating the knot in the direction of the cutting blade by a predetermined angle, reversely rotating the fish knot to the original position after cutting, and moving the fish knot to the fixed position in the feeding direction again The feature is that the fish section is repeatedly cut.

In the second device invention, a supply means for supplying a plurality of fish knots one by one, a chain conveyor arranged below the supply means and moved in the fish knot loading direction, and a lever provided by a cylinder. A node pressing plate that moves while keeping parallel to the conveyor via a link and presses the fish node supported by a receiving member disposed below the conveyor, and a node under the conveyor that holds the chain wheels at both ends of the conveyor. A node pressing piece protruding toward the pressing plate is provided, and it is composed of two parallel holding side plates joined by a connecting member, and is rotatably held by a fixed shaft penetrating the middle part of the two chain wheels. Means for holding fish section, cutting means for allowing a cutting blade attached to a rotating substrate to face the lower end rotation path of the fish section holding means, and the bottom section of the fish section for rotating the fish section holding means around a fixed axis. Part is moved within the turning path of the cutting blade. It is obtained by constituting the apparatus with the Sakanabushi oscillating means for early return to the smoked fish holding means to its original position after a fixed length cutting smoked fish.

Action The fish node sandwiched between the conveyor and the node pressing plate is rotated around the fixed axis by a certain angle and cut by the cutting blade attached to the rotating substrate. A certain length of the knot is cut by one rotation of the fish knot holding means. In this case, the width of the fish pieces to be cut is determined by the width of the cutting blade (or the dividing blade), and the thickness of the cut pieces is the speed at which the fish piece holding means is moved toward the rotating substrate,
It can be freely changed by the rotation speed of the cutting blade and the number of cutting blades mounted around the rotating substrate.

In addition, when cutting a single fish segment, after the constant length portion has been cut, the fish segment holding means is returned to the original position, the conveyor is moved to the cuttable position, and the previous cutting operation is repeated. However, since the returning speed of the fish-peg holding means is higher than the feeding speed, the cutting of the fish-peg is efficiently performed.

And a connecting link 52 to be connected. Reference numeral 53 is a pulse motor that rotates the screw shaft 49 in the forward and reverse directions via the gear train 54. The motor 53 is a reverse motor that moves the motion conversion block 51 to the left rather than a forward rotation when it moves to the right in FIG. The rotation speed is faster during rotation, and the fish pieces can be quickly returned after the fish pieces of a certain length have been cut. The movement range of the motion conversion block 51 is restricted by the first and second proximity switches 55 and 56. In addition, the operation of the air cylinder and each motor is performed by preset program control.

Rotate around to the position indicated by the chain double-dashed line. During this rotation, the fish node sandwiched between the chain conveyor 1 and the node pressing plate 2 is cut with a width dimension determined by the width of each of the divided blades 5 at a fixed length portion overlapping the rotation locus of the cutting blade 5 ( (See FIG. 5). In this case, the thickness of the shaving node changes the combination of the speed at which the fish node holding means B is moved toward the cutting means C, the rotation speed of the cutting blade 5, and the number of cutting blades 5 mounted around the rotary substrate 4. Therefore, it can be adjusted arbitrarily.

When the fish node holding means B is rotated to the position shown by the chain double-dashed line, the pulse motor 53 is stopped by the first proximity switch 55 and the pulse motor 53 is reversed at a speed faster than during forward rotation, and the motion conversion block
The 51 and the fish node holding means B are respectively quickly returned from the position indicated by the chain double-dashed line to the original position indicated by the solid line. When the motion conversion block 51 returns to its original position and its movement is stopped by the second proximity switch 56, the air pressure supplied to the air cylinder 28 is reduced and coupled to the shaft 20 of the chain wheel 22. The chain conveyor 1 is driven downward by a motor (not shown) with a clutch brake, and is stopped when the tip of the fish node comes into contact with the circular arc receiving surface 31a of the receiving member 31.

In this state, the pulse motor 53 is again rotated in the forward direction, the fish-node holding means B is swung around the fixed shaft 3 through the motion conversion block 51, and the fish node is cut at the next fixed length portion. It Therefore, by repeating the above-mentioned operation, the entire fish section can be cut into a predetermined width, length, and thickness. Moreover, when using this device, the fish knots are not held by the fish knot holding means B and are not pressed by the rotating substrate 4, so that the rotating substrate 4 can be rotated at a high speed to easily improve the cutting efficiency. You can

EFFECTS OF THE INVENTION According to the present invention, it is possible to repeatedly cut a fish node of a certain length which is rocked around the fixed shaft by swinging the fish node holding means for sandwiching the fish node and overlapping within the rotation locus of the cutting blade. Therefore, by appropriately determining the width dimension of the split blade, the width, length, and thickness dimension of the shaving node can be freely adjusted. Further, the fish pieces to be cut are not clamped by the fish piece holding means and are not pressed by the rotating substrate, so that the productivity during cutting can be significantly improved.

When the present invention is applied to a shaving knot for measuring bagging, a shaving knot having a size suitable for bagging can be produced by one cutting, so that the time exposed to air is reduced and the flavor is excellent. It is possible to produce shavings efficiently.
