Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an automatic squid fishing machine, and in particular, to an improvement in a shaving operation by a rotating drum.
[0002]
[Prior art]
Referring to FIG. 5 for convenience, the automatic squid fishing machine 1 is installed on the hull 2, and the rotating drum 5 is driven by a driving motor to cause the rotating drum 5 to perform a predetermined brushing operation. This is a device that activates the fishing line 25 wound around the fishing line to raise the squid. The shackle operation is to control the rotation of the rotary drum 5 to make the pseudo bait attached to the fishing line 25 look like a small fish. When the fishing line is wound up, the hoisting speed is changed. .
[0003]
The automatic squid fishing machine 1 is a one-way clutch (a clutch that is configured to rotate freely in the winding direction and not to exceed the rotational speed of the drive motor in the lowering direction in order to prevent troubles during lowering. ) Is provided. This is to prevent the fishing line from being fed out more than necessary. In other words, the lowering is basically a free fall that is lowered by the weight of the weight 27. When the force is lowered, the fishing line is fed out more than necessary, so that the fishing line 25 comes off from the rotary drum 5 and the front roller 26, etc. It is easy for trouble to occur. Further, if the rotational speed of the rotating drum 5 is slowed to prevent such “dandruff”, the time for one cycle of the hoisting / lowering operation becomes longer and the operation efficiency is remarkably lowered. Therefore, it is necessary to equip a one-way clutch in terms of preventing troubles during lowering and improving operational efficiency. For example, the one-way clutch is provided in a reduction device of a drive motor or the like.
[0004]
[Problems to be solved by the invention]
However, since the driving mechanism of the automatic squid fishing machine 1 is as described above, a phenomenon occurs in which the brushing operation of the rotating drum 5 does not coincide with the rotation of the driving motor. In other words, when the rotating drum performs a crushing operation, particularly in the winding direction, the load constantly fluctuates due to the shaking of the ship and so on.
[0005]
As for the inertia of the drive motor, by controlling the deceleration rate, the gap between loaded and unloaded can be eliminated, but this cannot cope with the fluctuation of the load itself.
[0006]
Therefore, the present invention eliminates the above-mentioned drawbacks, and with a trouble-preventing mechanism at the time of lowering, makes the rotation operation of the rotating drum constant without being affected by load fluctuations caused by ship swaying, etc. The purpose is to reduce the time variation of the machine's shaving operation and to improve the operation efficiency.
[0007]

DETAILED DESCRIPTION OF THE INVENTION
Next, an automatic squid fishing machine according to the present invention will be described in more detail with reference to the drawings showing embodiments. For convenience, portions having the same function are denoted by the same reference numerals and description thereof is omitted.
[0009]
The automatic squid fishing machine 1 includes a main body 3 and a rotating drum 5. The main body 3 is provided with a drive motor 9, a drive mechanism for controlling the rotational speed of the drive motor 9, and a control mechanism for controlling the drive mechanism. The drive motor 9 is controlled by the control mechanism via the drive mechanism to rotate the pair of rotating drums 5.
[0010]
FIG. 2 shows a drive mechanism in the main body 3. That is, a drive motor 9 is installed below the housing 7, and the driving force of the drive motor 9 is transmitted to the traverse shaft 13 via the chain 11 via the speed reducer 10. A one-way clutch 12 (shown in FIG. 3) is built in the speed reducer 10. The traverse shaft 13 is installed to move the drum mounting shaft 15 of the rotary drum 5 in the axial direction, and is connected to the drum mounting shaft 15 provided above by a chain 17 so as to be capable of transmission. The rotating drums 5 and 5 are rotatably fixed to both end portions of the drum mounting shaft 15. Reference numeral 19 denotes an encoder for measuring the rotational speed of the rotary drum 5, which is connected to the traverse shaft 13 by a chain 21 and measures the rotational speed of the drum mounting shaft through the rotation of the traverse shaft 13. An electromagnetically operated brake 23 is attached to one end of the traverse shaft 13. The brake 9 is composed of a powder brake, for example, and is controlled by a computer constituting a control mechanism.
[0011]
FIG. 3 shows an example of the one-way clutch 12. First, there is a drive shaft 12b provided with a pinion 12a at the tip. The driving force of the drive motor 9 is transmitted to the gear 12d that meshes with the pinion 12a at the tip of the drive shaft 12b. Then, as the gear 12d rotates, it is transmitted to the one-way plate 12c by a pin 12f embedded in the gear 12d and freely accessible by a spring 12g. Since the one-way plate 12c is provided with an engagement groove 12e tapered in the rotation direction, the one-way plate 12c and the pin 12f are engaged when rotating in the deep groove direction indicated by an arrow in FIG. Power is transmitted. When rotating in the reverse direction, only the pin 12f (gear 12d) is rotated, so no power is transmitted. 12h is an output shaft of the one-way plate 12c.
[0012]
When the drive motor 9 rotates in the winding direction, the gear 12d rotates in the clockwise direction when the drive shaft 12b rotates in the counterclockwise direction indicated by the arrow. Then, the pin 12f embedded in the gear 12d enters the engagement groove 12e of the one-way plate 12c as shown by an arrow in FIG. 3C, so that the driving force from the drive motor 9 is transmitted to the output shaft 12h. On the other hand, when the drive shaft 12b rotates in the clockwise direction indicated by the arrow, the pin 12f rotates in a direction (a direction opposite to the arrow in FIG. 5C) from the one-way plate 12c, so that the drive force from the drive motor 9 is applied to the output shaft 12h. Not transmitted (see FIGS. 3B and 3C).
[0013]
A fishing line 25 (shown in FIG. 5) is wound around the rotating drums 5 and 5 and is suspended in the sea via a front roller 26. A weight 27 is attached to the tip of the fishing line 25, and a pseudo bait (not shown) is attached at a predetermined pitch.
[0014]
An example of the control mechanism is shown in FIG. First, input means 101 is provided, and data inputted from the input means 101 is inputted to the control means 105 via the interface circuit 103. Further, a control signal is output from the control means 105 to the drive motor 9 via the interface circuit 103. The control means 105 includes a CPU 109, a ROM 111, and a RAM 113. Further, the CPU 109 can communicate with the centralized control device 30 via the communication means of the interface circuit 103.
[0015]
The squid fishing machine 1 is provided with a rotation monitoring means 115 for monitoring and detecting the rotation state of the rotary drum 5. A signal from the rotation monitoring unit 115 is input to the control unit 105 via the interface circuit 103.
[0016]
The thing of the same structure is installed about all the squid fishing machines 1 mounted in the hull 2. FIG.
[0017]
Next, the configuration of the central control device 30 will be described. First, there is a control means 116, and this control means 116 is composed of a CPU 117, a ROM 119, and a RAM 121. Further, there is an input means 123, and data inputted from the input means 123 is inputted to the CPU 117 through the interface circuit 125. Further, the interface circuit 125 is provided with a communication means, and transmission / reception of signals to / from each squid fishing machine 1 side is performed via the communication means.
[0018]
Each squid fishing machine 1 is provided with an operation panel (not shown), and the above-described input means 101, interface circuit 103, control means 105, etc. are built in the operation panel. Similarly, in the central control apparatus 30, another operation panel (not shown) is installed, and the input means 123, the interface circuit 125, the control means 116 and the like already described are incorporated in the other operation panel.
[0019]
FIG. 7 shows the relationship between the speed of the rotating drum 5 (drum speed) and the rotation area (drum area) in the shaving operation per unit cycle. In this embodiment, the unit period is 1 rotation, and 360 ° is divided into 72 equal parts, so the unit area is 5 °.
[0020]
In this case, the setting items for the brushing operation of the rotating drum 5 are as follows.
Rise speed 90 [%]
Maximum speed 100 [rpm]
Falling speed 80 [%]
Minimum speed 30 [rpm]
Low-speed rotation area 40 [area]
Cycle (1 rotation of rotating drum) 72 [area]
[0021]
The setting items of the brake 23 are as follows.
Brake amount 25 [%]
Offset value A 4 [area]
[0022]
8 and 9 schematically show the relationship between the rotation of the rotary drum 5 and the drum region, and also show the region of the brake operation by the brake 23. FIG. In the present embodiment in which the unit period as one rotation, while the rising speed of the T ₀ point to T ₁ point (FIG. 9 (A)), between _one point or T ₂ points T is the maximum speed (Fig. 9 ( B)), the falling speed between _{T 2} points to _{T 3} points (Fig. 9 (C)), during of _{T 3} points to _{T 0} point is the area of the minimum speed (Fig. 9 (D)). The region from the front of a point from the _two-point T to point b after the T ₃ points is the region of the brake ON.
[0023]
The driving force from the drive motor 9 is transmitted to the drum mounting shaft 15 from the traverse shaft 13 to which the brake 23 is mounted through the speed reducer 10 and the one-way clutch 12, and the rotating drum 5 is rotated to a predetermined depth. A predetermined shadowing operation is performed.
[0024]
Next, referring to the operation of the drive motor 9 shown in FIG. The rotating drum 5 rises to the maximum speed during the 10 regions from the T ₀ point to the T ₁ point as the base point, and then maintains the maximum speed until the T ₂ point (32nd region). Up to this point, the motor operation and the drum operation are the same. However, the two do not match at the fall of the shackle operation.
[0025]
That is, the driving motor 9 becomes minimum predetermined speed between (52 area th) among _three points T, to maintain a minimum speed subsequent to the base point T _0. On the other hand the operation of the rotary drum 5, enters the low-speed rotation region of the _two points after T, due to the effect of inertia, gradually deviate from the motor operation.
[0026]
However, in the present embodiment is set offset value A and four regions, the brake is turned ON at the position of the 4 regions short of ₂ points T. Further, since the amount of brake is set to 25%, the brake operation by the brake 23 is continued from the _3-point T until after 4 region.
[0027]
Therefore, the brake operation becomes a line indicating the fall of the rotating drum 5 indicated by a dotted line in FIG. 7, that is, a line indicating the actual rotation of the rotating drum 5, and is operated until the rotating drum 5 reaches a predetermined minimum speed of 30 rpm. to continue. For this reason, the actual rotation of the drive motor 9 and the actual rotation of the rotary drum 5 can be made substantially the same by setting the brake amount in consideration of the load at the time of falling of the shackle operation in which the divergence phenomenon occurs. .
[0028]
The above will be confirmed in accordance with the brake operation flowchart shown in FIG. First, it is determined in S1 whether or not it is the start position of the brake 23. If YES, the brake amount is set and the brake is turned on (S2). The start position of the brake 23 is whether or not the current position of the rotary drum 5 has reached the offset value A (four regions in this embodiment) set for starting the brake operation from the start position of the falling speed (this example). In the embodiment, it is determined by the 28th region). When braking progresses and the actual rotation of the rotating drum 5 decreases, it is determined in S3 whether or not the brake 23 is at the end position. If YES, the brake operation is turned off (S4). The end position of the brake 23 is determined based on whether or not the actual rotational speed of the rotary drum 5 is a preset minimum speed. Each of the above determinations is performed by the control mechanism described above based on a signal from the encoder 19 that reads the rotational speed of the drum mounting shaft 15 through the rotation of the traverse shaft 13.
[0029]
As described above, according to the present embodiment, the actual rotation of the drive motor 9 and the actual rotation of the rotary drum 5 can be made substantially the same at the time of falling of the shackle operation. Even if there is an accompanying load change, it is not affected by this. Therefore, the rotation of the rotating drum 5 can be controlled in real time, and the shaking operation of the rotating drum 5 can be freely controlled. As a result, the shaking operation of the rotating drum 5 becomes constant (shaking operation stability), the variation in time of the shaking operation in one cycle of each machine mounted on the hull 2 is reduced, and the operation efficiency is greatly improved. There is.
[0030]
The divergence phenomenon varies depending on the setting value of the shackle operation, the load on the fishing line 25, and the like. Therefore, the position of the brake operation ON is appropriately determined in consideration of the response capability of the brake 23 and the like. As in this embodiment, when one rotation of the rotary drum 5 is set as a unit period and this is divided into 72 equal parts, the offset value A is preferably adjustable up to five areas before.
[0031]
It is also desirable that the brake amount (brake strength) be adjustable. In such a case, it is possible to perform a crushing operation close to the operation of the drive motor 9 (sharpening operation with sharpness, easy to bite), and a crushing operation that leaves a little inertia (smoothed crushing operation and impact applied to the machine) Can be reproduced).
[0032]
In the above embodiment, the brake operation is automatically turned off when the actual rotation of the rotary drum 5 becomes equal to the set value of the minimum speed. There is an effect that 9 is not burdened.
[0033]
Furthermore, since there are two items for setting the brake operation, it is possible to exhibit sufficient functions without impairing operability.
[0034]
The present invention is not limited to the embodiment described above. For example, the unit period can be changed to an arbitrary numerical value. The unit area can also be changed to an arbitrary number. In addition, the numerical values of the setting item for the shackle operation and the setting item for the brake operation can be arbitrarily changed.
[0035]
It is also possible to set the start position of the brake operation by the operating time without setting it in the area. In the latter case, it may be calculated several seconds before the end point of the maximum speed of the rotating drum, and the unit cycle It may be calculated from the base point (To).
[0036]
Further, the end position of the brake operation is not automatic and can be set by n unit areas or by the operation time. In the case of the latter two, for example, the calculation starts from the base point (To) of the unit period.
[0037]
Further, the central control device 30 described in the above embodiment is not necessarily used.
[0038]
Further, the unit period may be different between the previous period (for example, 1 rotation) and the current period (for example, 2 rotations), and the braking operation may be performed for each unit period of the rotating drum 5.
[0039]
Further, the brake operation method is arbitrary.
[0040]
Further, the mounting position of the brake may be after the one-way clutch, and ideally the drum mounting shaft of the rotating drum is desirable.
[0041]
In addition, the cause of the load in this invention is not ask | required. For example, it can be applied not only to the shaking of a ship but also to the magnitude of the load caused by the amount of fishing.
[0042]
【The invention's effect】
Thus, according to the automatic squid fishing machine according to the present invention, in the state where the trouble prevention mechanism at the time of lowering is left, even if there is a change in load, the shackle operation is made constant, thereby further increasing the efficiency of operation and catch. Increase can be achieved.
