Description

[Detailed description of the invention] [Industrial application field] This invention relates to a fish alignment and protrusion device, and more specifically, it uses a diaphragm to capture flat fish such as flatfish and perciformes. This invention relates to a fish alignment and projection device that discharges fish with their heads and tails aligned in the same direction.

[Prior Art] This type of fish body alignment device is conventionally described in, for example, Japanese Utility Model Application Publication No. 100587/1983.

This conventional technology involves erecting a large number of elastic small columnar protrusions at small intervals vertically and horizontally on a horizontal alignment plate that reciprocates in the longitudinal direction by an appropriate drive mechanism, and This is a fish body aligning device in which a side wall plate that is inclined diagonally outward is integrally provided on the edge of the fish body, and both ends thereof are formed into transport ports.

[Problems to be solved by the invention] In the conventional technology described above, the bottom plate into which a large number of fish bodies are to be transported is moved only horizontally by a crank attached to the rotating shaft of the machine, via a connecting rod, and a pin, and by a sliding member. Since the fish are moved back and forth, the large number of fish bodies would not be aligned and transport would not be possible without the large number of columnar protrusions arranged on the bottom plate.

In other words, since the conventional method requires a large number of columnar protrusions, the first problem is that the fish body is scratched by the columnar protrusions, resulting in damage to the fish body and a significant drop in commercial value. .

In addition, the scales and pieces of flesh that have come off from the fish body due to the above-mentioned scraping fall between the many columnar protrusions and cause clogging, which causes the many columnar protrusions to become stiff and the ability to transport and align the fish body to be extremely reduced. The second problem is that cleaning the clogged scales and pieces of meat is complicated and difficult.

In order to eliminate each of the above-mentioned problems, this invention vibrates a diaphragm along an arcuate locus centered on its hinge with an elastic plate-like member via a spring. The purpose is to align the head and tail directions by vibrating in two directions: vertically and horizontally.

[Means for Solving the Problems] The purpose of this invention described above is to attach the vicinity of each corner of a diaphragm having opposing side plates to the upper end of an elastic plate-like member attached to a base via a hinge. A reciprocating motion conversion mechanism including a rotating machine such as a motor and an eccentric shaft, a crankshaft, etc. for converting the rotational motion of the rotating machine into reciprocating motion is provided on the base, and the reciprocating motion is supported on a base. A crankshaft in a dynamic conversion mechanism is coupled to the diaphragm via an elastic member such as a spring, and the diaphragm is vibrated along an arc locus centered on the hinge via the elastic plate member. This is achieved by vibrating the fish placed on the diaphragm in two directions, vertically and horizontally, to align the head and tail directions.

[Operation] A crankshaft in a reciprocating motion conversion mechanism that converts rotational motion of a rotating machine into reciprocating motion is coupled to a diaphragm via a spring, and the diaphragm is moved around the hinge via the elastic plate member. By vibrating the fish along an arcuate trajectory, the fish placed on the vibrating plate are vibrated in two directions, vertically and horizontally, and their heads and tails are aligned and projected to a desired location, keeping the fish aligned. Can be packed in boxes.

[Example] Examples will be constructed with reference to the drawings.

The basic structure of the fish alignment and protrusion device of this invention is as shown in FIGS. 1 to 3a and 3b,
The vicinity of each corner of the diaphragm 22A having opposing side plates 22, 22 is attached to the upper part of elastic plate-like members 23, 23 attached to the base 1 via hinges 24, 24, and the diaphragm 22A is placed on the base 1. A reciprocating motion conversion mechanism consisting of a rotating machine such as a motor 6 and an eccentric shaft 18, a crankshaft 19, etc. for converting the rotational motion of the rotating machine into reciprocating motion is provided on the base, and the reciprocating motion The crankshaft 19 in the dynamic conversion mechanism is coupled to the diaphragm 22A via an elastic member such as springs 29A, 29B, and the diaphragm is centered at the hinge via the elastic plate members 25, 25. This is a fish aligning and protruding device that vibrates the fish placed on the diaphragm 22A in two directions, vertically and horizontally, by vibrating along an arcuate locus to align the head-to-tail directions.

More specifically, as shown in each of the above figures, the other end side of the metal base 1 which has been subjected to corrosion prevention processing and the one end side of the top surface 4 which has convex portions 2 and 3 at the center are equipped with a deceleration mechanism as a rotating machine. The machine 5 and the motor 6 are fastened and fixed with bolts and nuts.

A pair of bearings 7 are mounted on the convex portion 2 on the other end side of the base 1.
a and 7b are tightened and fixed with bolts, and this bearing 7
A pulley 9 is attached to one end of the rotating shaft 8 which is supported horizontally and rotatably in the width direction of the base 1 by a and 7b, and a V-belt is connected between the pulley 9 and the pulley 10 attached to the output shaft of the reducer 5. 11 is suspended, and a rotating disk 12 is key-locked to the other end.

Further, as shown in FIG.
4a, 14b are mounted parallel and horizontally, and the supporting members 13a, 1 are supported by the guide shafts 14a, 14b.
A pair of integrated sliding pieces 15a, 15b are supported via a connecting plate 16 which is shorter than the interval between the two sliding pieces 15a, 15b, and the sliding pieces 15a, 15b are inserted through a through hole drilled in the center of the support member 13a. It is fixed to the follower rod 17.

On the outside of the rotating disk 12, there is an eccentric shaft 18 at a position offset from the center of the disk 12 as a reciprocating motion conversion mechanism for converting rotational motion into reciprocating motion.
is provided protrudingly from the eccentric shaft 18.
A crankshaft 19 is connected to the end of the crankshaft 7 via a universal joint 20, and is attached via a coupling member 21.

With approximately the same area as the top surface of the base 1, both sides in the width direction are bent to one side to form a side plate 22, and a plurality of protrusions 23 parallel to the length direction are formed on one surface at regular intervals. One end of the diaphragm 22A is attached near the four corners of the top surface of the base 1, and the other end of four elastic plate-like members 25 are attached near each corner of the base 1 via hinge mechanisms 24, 24, respectively. It is supported on the base 1 by fixing it via the mounting fittings 26.

A substantially U-shaped mounting bracket 27 is attached to the center of the lower surface of the diaphragm 22A, and a bolt 28 is attached with a nut between the end plates formed by bending at both ends of the mounting bracket 27. and two springs 29a, 29b and nuts 30a, 30b.
are inserted and screwed.

Further, as shown in FIG. 4, in the center of the connecting plate 16, an engaging fitting 34 is provided with a cut groove 33 slightly wider than the diameter of the bolt at its end via a mounting fitting 31.
is mounted vertically, and the pair of springs 29
A bolt 28 is installed between a and 29b so as to enter into the cut groove 33, and elastically connects the connecting plate 16 and the diaphragm 22A.

In the figure, 35 is a drip-proof cover having an opening 36 wider than the width of the mounting bracket 27 and sufficiently longer than the length thereof, 37 is an adjustment bolt, and 38 is a vibration isolating member.

The fish alignment and protrusion device A of this invention is constructed as described above, and is installed on the floor surface 39 of the workplace via the vibration isolating member 38.

Further, although not shown in the figure, a belt conveyor for transporting the lined up fish is placed near both ends of the diaphragm 22A, and a shutter for feeding the fish onto the diaphragm is arranged in the center of the diaphragm 22A. has been done.

In the fish alignment and projection device A of this invention, the motor 6 rotates when a power switch (not shown) is turned on.
The output of this motor is reduced by a speed reducer to 1/10 to 1/50 and applied to the rotating shaft 8 via the V-belt 11.
A crankshaft 19 eccentrically connected to the rotating shaft is reciprocated.

This reciprocating motion of the crankshaft 19 also causes the follower rod 17 connected via the universal joint 20 to reciprocate, causing a pair of sliding pieces 15a, 15b fixed to this follower rod 17 to reciprocate along the guide shafts 14a, 14b. During this movement, the diaphragm 22A, which is engaged with the engaging metal fitting 34 fixed to the connecting plate 16 via the springs 29a and 29b, is vibrated.

In this case, the diaphragm 22A lags behind the movement of the engagement fitting 34 until the spring 29a is compressed, and once compressed, it moves in one direction at the same speed, and returns from the maximum amplitude point in one direction to the other direction. is the same until it passes through the amplitude midpoint, and in the other direction, it lags behind the movement of the engagement fitting 34 until the spring 29b is compressed, and when it is compressed, it moves in the other direction at the same speed.

That is, the diaphragm 22A is connected to the elastic plate member 2.
The diaphragm 22A is vibrated along an arcuate locus centered on the hinge via the diaphragms 5 and 25.
The fish placed on top can be vibrated in two directions (up and down and horizontally) to align their heads and tails.

When a fish is fed through the shooter onto the diaphragm 22A which repeats non-uniform vibrations, that is, vibrations in the upward, downward and horizontal directions, the vibration of the diaphragm 22A causes the fish B to move its heavy head to the diaphragm 22A. Move toward both ends.

At both ends of the diaphragm 22A, the fish are oriented, transferred to a belt conveyor, and transported to a boxing workshop.

Accurate alignment can be achieved by allowing the frequency and amplitude of vibration of the diaphragm 22A and the width and height of the protrusions 23 to be freely selected in advance depending on the size and type of fish to be aligned.

[Effects of the invention] Since this invention is configured as described above, it produces the effects described below.

That is, by vibrating the diaphragm along an arcuate trajectory centered on the hinge via the elastic plate-like member, the fish placed on the diaphragm is vibrated vertically and horizontally to align its head-to-tail direction. Therefore, it is possible to align a large number of fish bodies without the need for a large number of columnar protrusions arranged on a diaphragm as shown in the above-mentioned prior art, and in this aligned state, the fish bodies can be transported and protruded into a box. .

In other words, the first problem is that the conventional method requires a large number of columnar protrusions, so the fish body is scratched by the large number of columnar protrusions, which damages the fish body and significantly reduces its commercial value. This problem could be solved with this invention.

In addition, the second problem seen in the conventional example is that the scales and pieces of flesh peeled off from the fish body by the above-mentioned scraping fall between the numerous columnar protrusions and cause clogging, resulting in the large number of columnar protrusions being separated. This invention solves the second problem of the conventional technology, which is that the ability to transport and arrange fish bodies is extremely reduced due to the lack of water, and that cleaning of clogged scales and pieces of meat is complicated and difficult. .

In addition, this invention does not require the provision of many columnar protrusions on the diaphragm at all, so it not only solves the various problems during use as described above, but also provides it to fish processing sites at a low cost. It has many effects such as:
