Description

  The present invention relates to a hitting device for hitting a fish head to kill or stun the fish.

As a conventional hitting device that kills or faints without reducing freshness in order to obtain a fish egg from fish such as salmon, a conventional fish hitting the fish inserted in the device is stopped at a predetermined position. There is a structure in which the head of a fish is hit with a hammer at this position where the fish is killed or stunned. (For example, see Patent Document 1)
JP-A-11-239444 ()

By the way, the position where the fish is effectively hit against the head is limited, and unless the position is hit accurately, the fish will not be stunned with a single shot, and the fish that can be hit many times will be rampant. Since blood circulates into the body and adversely affects fish eggs and fish, it is necessary to accurately position the head of fish.
However, because the size and length of the head of each fish is different for each individual, the tip of the head of the fish is brought into contact with the fish to stop at a predetermined position as in the stopping means disclosed in Patent Document 1. Therefore, in the case where the forward movement is prevented, the position of the head may be incorrect depending on the size of the individual, which may have an adverse effect on the fish egg and the fish body.

  Therefore, the present invention aims to accurately strike the head regardless of the size of the fish, to maintain the freshness of the fish so as not to adversely affect the fish eggs and fish body. The purpose of the present invention is to provide a fish hitting device that solves the above problem.

The present invention employs the following technical means to achieve the above object.
In a fish hitting device in which a fish is held by hitting the head of the fish with the hitting means and the fish is stunned or killed, an optimum hitting position in the head of the fish is displayed by light, and the displayed position is displayed. The hitting means is applied to the part, and the fish inserted into the device is adjusted back and forth so that light is projected to an optimum position of the head, and the light is projected to the optimum position. Give a blow in the state. (Claim 1)
The optimum hitting position in the head of a fish is a portion called an "ice head". By accurately hitting the "ice head", the fish are surely stunned or killed. be able to.
The front and rear adjustment of the fish is adjusted so that the worker holds the vicinity of the tail of the fish and projects light onto the “ice head”.

The striking means of the present invention includes at least all means capable of striking the head of a fish, for example, an arm that is rotatably supported in a direction that alternately approaches and separates the fish. A hitting portion with a rounded tip is provided on the front side of the supporting portion, and the hitting portion hits the head of the fish by turning in the approaching direction of the arm, and the arm turns in a direction to separate after hitting. The structure can be exemplified. (Claim 2)
In this case, the rotation of the arm in the approaching direction is performed by rotating the arm by power from the start of rotation to halfway, and is separated from the power during rotation from halfway to impact, and is rotated by power. It is preferable that the arm be rotated by free fall due to the inertia obtained by the movement and the weight of the arm. (Claim 3)
As a configuration for efficiently hitting the head of the fish, a configuration is preferable in which the fish is held such that the hitting portion strikes the fish at an almost right angle with respect to the optimum position of the head of the fish. (Claim 4)

In addition, in order to improve work efficiency, when inserting fish, preparation for operating the hitting means is started at the same time as detection of the presence of the fish, and the operator is notified of the start of the preparation, and is set in advance. It is preferable to control the striking means to operate after a lapse of time. (Claim 5)
Means for detecting the presence of fish include a limit switch that is turned ON / OFF by an inserted fish, an optical sensor, a weight sensor, and the like.

The present invention has the following excellent effects by the above configuration.
According to the invention of claim 1, by adjusting the light so as to be projected on the ice head in the head of the fish in a state where the fish is inserted, the ice head is reliably hit and the fish is shot once. Stunned or lethal at
Therefore, regardless of the size of the fish, the hit to the ice head can be performed accurately, so that it is possible to provide a hitting device capable of maintaining the freshness of the fish and stunning or killing the fish without adversely affecting the fish egg or the fish body. .
Further, according to the invention of claim 2, since the tip of the hitting portion is formed round, it is possible to hit the ice head without piercing the ice head or crushing the ice head at the time of hitting. In addition, the adverse effect on the fish body can be further suppressed, and the impact is given by the rotation of the arm, so that the structure is simple and greatly contributes to the reduction of the manufacturing cost and various maintenance costs.
Further, according to the invention of claim 3, by hitting the ice head by the inertia force obtained by the power from the rotation start to the middle and the free fall force due to the weight of the arm, the ice head is hit against the ice head. Since no further force is applied after the impact is applied to cause the impacted portion to penetrate, this greatly contributes to further suppression of adverse effects on the fish.
Furthermore, according to the invention of claim 4, since the hitting portion is made to contact the ice head at a right angle, the dispersion of the force at the time of hitting is suppressed, and the force can be concentrated on the ice head, so that the fish ice The hit to the head can be performed efficiently.
According to the invention of claim 5, the work efficiency is improved by automatically operating the striking means when the fish is inserted, and the worker is informed that the striking means operates. By providing a certain amount of time from the detection of fish to the operation of the striking means, it is possible for the operator to adjust the position where the light is projected onto the ice head, and to allow the operator to adjust the position of the striking means. The time until the operation can be changed according to the preference of the operator.

An embodiment of the present invention will be described below with reference to FIGS.
The striking device 1 according to the present embodiment includes a striking means 2 for striking an ice head B1 of a fish B on an upper surface of a worktable A, and a striking position display unit 3 for displaying a striking position P to a worker by projecting light. A limit switch 4 for detecting the presence of fish and operating the striking means 2, a lamp 5 for notifying an operator that the striking means 2 is activated when the limit switch 4 is turned on, and a holder for holding fish. 6 is provided.

The operation of the striking means 2 is such that when the limit switch 4 is turned on, the insertion of fish is detected, and a timer (not shown) is actuated based on the detection result, and at the same time, the striking position display means 3 is operated. And the lamp 5 are turned on, and the striking means 2 is operated after a preset time has elapsed.
Further, after the striking means 2 is hit, the striking means 2 is returned to the home position before the striking, and when the struck fish is removed, the limit switch 4 is turned off, the timer is reset, the striking position display section 3 and the ramp 5 are turned off. Is turned off.
The control of the striking means 2 is not limited to the control described above.

The striking means 2 includes an arm 22 having a striking portion 21 at the tip, a shaft 23 that supports the arm 22 so as to be freely rotatable in a direction to approach and separate from the fish B, and a fish 23 A power shaft portion 24 that supports the power shaft portion 24 so as to be rotatable in a direction approaching / separating from B, a power portion 25 that rotates the power shaft portion 24, and a stopper that regulates the rotation of the arm 22 in the approach direction. A part 26 is provided.
The free rotation of the arm 22 in the separating direction is further restricted by the stopper 27 at a position substantially parallel to the upper surface of the worktable A in a state before operation (shown by a solid line) shown in FIG. .
Reference numeral 28 denotes a support that supports the distal end portion of the arm 22 in a state before the operation, thereby suppressing deformation and breakage due to bending of the arm 22.

The shaft 23 is supported by a base plate 23A fixed to the power shaft 24.
The base plate 23A is held substantially perpendicular to the upper surface of the worktable A in a state before the operation shown in FIG.
The stopper portion 26 is attached to the base plate 23A. The stopper portion 26 regulates the rotation of the arm 22 in the approaching direction in the hitting state (shown by the phantom line) and rotates the power shaft portion 24 in the separating direction. The arm 22 is rotated so as to push up by the rotation of the base plate 23 </ b> A caused by the rotation.

The power shaft 24 rotates in accordance with the operation of the power unit 25 in the approaching / separating direction, and the amount of rotation is regulated to approximately 90 degrees by controlling the power unit 25.
That is, in the state before the operation shown in FIG. 1, the base plate 23A is substantially perpendicular to the upper surface of the worktable A as described above, and when the power shaft 24 rotates in the approaching direction from this state, the base plate 23A It stops at a position substantially parallel to the upper surface of the worktable A.
At this time, the arm 22 is rotated by the power shaft 24 until the arm 22 becomes substantially perpendicular to the upper surface of the worktable A, and the rotation from the position to the impact is obtained by the power rotation by the power shaft 24. Rotation in the approach direction is performed by the inertia force and the free fall force due to its own weight from the substantially vertical position, and these forces become the impact force of the fish B against the ice head B1.
The shape of the hitting portion 21 is formed by rounding the tip portion, so that when hitting the ice head B1, the hitting portion 21 does not stick to the ice head B1 and does not adversely affect fish.
Further, as other forms of the striking portion 21, for example, those shown in FIGS. 4 and 5 can be cited, and in each case, the tip of the striking portion 21 is formed round.
The strength of the striking force is determined by the rotation speed of the power unit 25. The lower the rotation speed is, the lower the inertia force is. Therefore, the lower the rotation speed is, the lower the striking force is. The higher the rotation speed is, the higher the inertia force is. The hitting power increases.

The striking position display means 3 is located immediately above the striking position P of the striking portion 21 and displays the striking position P with light.
The striking position display means 3 is illuminated when the fish B is inserted into the holder 6 and the limit switch 4 is turned on, and the worker projects light projected on the ice head B1. By adjusting the fish B back and forth as described above, the fish B can be brought to a position where an accurate blow is made.

When the lamp 5 is turned on, the operation of the striking means 2 is ready, and the operator is informed in advance that the striking means 2 will be activated after a certain period of time.
The holder 6 is formed in such a shape that the fish B can be held so as not to be tilted right and left when the fish B is inserted, and the front and rear adjustment of the fish B can be performed without any resistance.
The lower surface portion 61 of the holder 6 has an angle C such that the hitting portion 21 can hit the ice head B1 at a substantially right angle to the ice head B1. At a position where light is projected, the striking portion 21 can strike the ice head B1 at a substantially right angle.

In the hitting device 1 exemplified above, the rotation direction of the arm 22 in the hitting means 2 is set to a direction along the longitudinal direction of the fish B. In this direction, it is possible to hit the ice head B1. If possible, the striking means 2 in which the rotation direction of the arm 22 is set to a direction intersecting the longitudinal direction of the fish B may be used.
In the above embodiment,
The present invention is not limited to the configuration exemplified above, and other configurations can be made without departing from the contents described in each section of the utility model registration claims.
