Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention, in a fishing hoisting apparatus equipped on a fishing boat, enables early detection of a possibility that a fishing line may come off from a guide roller to take a prompt action. Of the fishing hoisting device that can prevent the decrease of fishing volume and the inadvertent damage of fishing gear by enabling to take quick action by detecting the line clogging between fishing lines. The present invention relates to a fishing line monitoring method and a fishing line monitoring device.

[0002]

2. Description of the Related Art A hoisting device for fishing, for example, a squid fishing machine equipped on a fishing boat has a structure as shown in FIG. That is, the fishing boat 1 is provided with the winding drum 3, and the fishing line 5 is wound around the winding drum 3 so that the fishing line 5 can be unwound and wound. Also, the guide member 7 projects from the fishing boat 1.
A front roller 9 as a guide roller is rotatably attached to the tip of the guide member 7. Then, the fishing line 5 is fed out or wound up in a state of being hooked on the front roller 9 from above.

The front roller 9 has, for example, a structure as shown in FIG. First, there is a core rod 11, and a body 13 is rotatably attached to the outer periphery of the core rod 11. A pair of roller trays 15a and 15b are rotatably attached so as to sandwich the body portion 13 from the left and right sides. The front roller 9 itself does not have a rotating means, and the body part 13 and the roller trays 15a and 15b are rotated by unwinding and winding the fishing line 5 hung there.

[0004]

The above-mentioned conventional structure has the following problems. That is, when the sea is on the brink during operation, the fishing boat may cause a phenomenon such as pitching and rolling, which
The fishing line 5 may come off the front roller 9. When the fishing line 5 is disengaged from the front roller 9 as described above, the catch may be missed or the fishing gear may be damaged.

Here, how the fishing line 5 is changed by the pitching / rolling phenomenon will be described with reference to FIGS. 9 and 10.
Will be described in detail with reference to. First, when the swing of the fishing boat 1 is small due to the pitching / rolling phenomenon, as shown in FIG. 9, the fishing line 5 does not come off from the front roller 9, and the front roller 9 is also in contact with the fishing line 5. So fishing line 5
It is rotating in a state commensurate with the feeding and hoisting speed of.
On the other hand, when the swing of the fishing boat 1 due to the pitching / rolling phenomenon is large, as shown in FIG. 10, the fishing line 5 is separated from the front roller 9 and floats. In that case, the front roller 9 stops its rotation, or the rotation speed becomes low. Then, the fishing line 5 may come off the front roller 9 as it is from the state shown in FIG. In that case, as described above, the catch may be missed or the fishing gear may be damaged.

[0006] As another problem, there is a problem that the line of the fishing line 5 is caught. Normally, the pair of fishing lines 5 and 5 attached to the same squid fishing machine perform the same type of operation, so that the fishing lines do not entangle with each other. On the other hand, there is a case where different types of operations (for example, one is a hoisting operation and the other is a payout operation) are being performed between each of the other adjacent squid fishing machines. In such a case, Adjacent fishing lines 5 and 5 may entangle each other, which may cause the catch to be lost or the fishing gear to be damaged, as in the case of the off-line. Is.

The present invention has been made on the basis of such a point, and an object of the present invention is to detect, for example, whether or not the fishing line may come off before it comes off the guide roller, and the fishing line comes out from the guide roller. Provided are a fishing line monitoring method and a fishing line monitoring device for a fishing hoisting device, which makes it possible to minimize damage caused by falling off and detect line clogging between fishing lines, and to take prompt measures. To do.

[0008]

In order to achieve the above object, a fishing line monitoring method for a fishing hoisting device according to the present invention is such that the fishing line wound on a winding drum mounted on a fishing boat is attached to the fishing boat. In a fishing line monitoring method of a fishing hoisting device configured to feed or hoist through a guide roller, the rotation speed of the guide roller is detected and the detected value

[0010]

In the present invention, the state of the fishing line is monitored by monitoring the rotation speed of the guide roller, and the line detachment of the fishing line, the line clogging between the fishing lines, etc. can be quickly detected and detected. You will be able to deal with it. That is, for example, when the fishing line starts to separate from the guide roller, the rotation speed of the guide roller decreases or the rotation of the guide roller is stopped, or the adjacent fishing lines are entangled with each other, the rotation speed of the guide roller increases. If the fishing line becomes smaller or stops its rotation, it is necessary to detect it and detect the possibility before the fishing line comes off the guide roller or before the fishing line is caught between the fishing lines. It is possible to take quickly.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of the present invention will be described below with reference to FIG. Incidentally, the same parts as those of the conventional one are designated by the same reference numerals and the description thereof will be omitted. First, in the case of this embodiment, the front roller 9 is provided with front roller rotation speed detecting means 101 as guide roller rotation speed detecting means for detecting the rotation speed of the front roller 9. The front roller rotation speed detecting means 1
01 has the following configuration. First, the external gear 103 is rotatably arranged on the outer peripheral side of the core rod 11,
An internal gear 105 meshes with the external gear 103. A rotation detector 107 is coaxially attached to the internal gear 105. That is, the external gear 103 rotates with the rotation of the body portion 13, whereby the internal gear 105 rotates. By detecting this by the rotation detector 107, the number of rotations of the front roller 9 and thus the rotation speed are detected.

The detection signal of the rotation detector 107 is input to the control means 109 of the squid fishing machine. Control means 109
Is the preset speed of the fishing line 5 and the detected rotational speed of the front roller 9 , that is, the set front roller 9
And the detected rotational speed of the front roller 9 are compared and calculated to calculate the difference, and it is determined whether or not the difference is within a preset allowable value. If the allowable value is exceeded, it is determined that the fishing line 5 may come off the front roller 9, and a signal to that effect is output.
After that, necessary measures are taken based on the alarm signal to prevent the fishing line 5 from coming off the front roller 9.

According to the present embodiment as described above, the rotation speed of the front roller 9 is constantly monitored, and how it is in relation to the preset speed of the fishing line 5 is compared. Since it is determined whether or not there is a possibility that the fishing line 5 has come off the front roller 9, the phenomenon of the fishing line 5 coming off the front roller 9 can be prevented.
This can result in inadvertent drop of catch, or
It is possible to prevent situations such as damage to fishing gear.

Next, a second embodiment of the present invention will be described with reference to FIG. In the case of this embodiment, as in the first embodiment, in addition to comparing the rotation speed of each front roller 9 with the set speed of the fishing line 5, the rotation speed of another adjacent front roller 9 is compared. The above-mentioned comparison is carried out, and whether or not there is a possibility that the fishing line 5 is detached from the front roller 9 is determined by monitoring both of them. That is, as shown in FIG. 2, a pair of rotary drums 3, 3 and a pair of front rollers 9, 9 are arranged in one squid fishing machine 2, and fishing lines 5, 5 are respectively hung on them. . Usually, it is rare that such a pair of fishing lines 5 and 5 simultaneously come off the respective front rollers 9 and 9. In other words, due to the pitching / rolling phenomenon of the fishing boat 1, the fishing boat 1 swings back and forth and left and right irregularly, and both of the pair of adjacent fishing lines 5 and 5 are disengaged from the respective front rollers 9 and 9. It is hard to think.

Therefore, the rotational speeds of a pair of adjacent front rollers 9, 9 are compared with each other, and if the difference is out of the allowable range with respect to a preset value, the fishing line 5 Is determined to be disengaged from the front roller 9. Then, the rotation speed of each front roller 9 and the set speed of the fishing line 5 are compared / determined, and the adjacent front rollers 9 are
The presence / absence of the possibility that the fishing line 5 is disengaged from the front roller 9 is determined from both the comparison and determination of the rotational speeds of the fishing lines 9. As a result, the detection / discrimination accuracy becomes higher. Incidentally, reference numeral 2 in FIG. 2 indicates a drive unit (for example, a drive motor).

Next, a third embodiment will be described with reference to FIGS. In the case of this embodiment, the configuration in which the rotation speed of the front roller 9 is monitored is used to detect the line clogging between the fishing lines 5 between a pair of adjacent squid fishing machines. FIG. 3 shows two adjacent squid fishing machines, in which the left side is the machine 1 and the right side is the machine 2. Each machine has a pair of fishing lines 5, 5,
The front rollers 9 and 9 are respectively used to feed and wind. The machine 1 winds down the pair of fishing lines 5 and 5, and the machine 2 winds up the pair of fishing lines 5 and 5. In such a case, as shown in the figure, the fishing line 5 on the lowering side and the fishing line 5 on the hoisting side
It is expected that and will get caught in the thread. Specifically, in the machine 1, although the left front roller 9 is rotated normally, the right front roller 9 by the yarn cult, and its rotation speed is slower, resulting in stop sometimes Yonako There is also. Further, in the machine 2, the right front roller 9 is normally rotating, but the left front roller 9 may be slowed in rotation speed due to thread clogging and may be stopped in some cases. . Such a thread clogging phenomenon is automatically detected by monitoring the rotation speed of the front rollers 9, 9 of each machine.

FIG. 4 shows the configuration of a control device for performing the above detection. First, the number setting switch 121, the left roller rotation speed detection sensor 123, and the right roller rotation speed detection sensor 12
5, an encoder 127, a motor control circuit 129,
These are connected to a CPU (Central Processing Unit) 133 via an I / O port 131. Also, the above CP
The U (central processing unit) 133 includes a data transmission circuit 1
35, ROM 137, and RAM 139 are connected.

Next, with reference to the flow charts of FIGS. 5 and 6, what steps are actually performed for detection will be described. First, the speed of the fishing line 5 is calculated (sequence S1). Next, the number of rotations of the front roller 9 is calculated and set as (X) (sequence S2). Next, the number of rotations of the left front roller 9 is detected and set as (Y) (sequence S3). Next, the number of rotations of the right front roller 9 is detected and set as (Z) (sequence S4). Next, the process proceeds to sequence S5, and it is determined whether or not (XY) is equal to or greater than the detection reference value (B). Then, when it is equal to or larger than the detection reference value (B), the sequence proceeds to the sequence S6 and the constant (C) is set to "1". Then, the process proceeds to a sequence S7, and it is determined whether or not the film is being hoisted. If the film is being hoisted, the process goes to a sequence S8 shown in FIG. On the other hand, when the machine is not being hoisted, the process proceeds to sequence S9, it is determined that there is an abnormality, and the machine is stopped.

If the difference is less than the detection reference value (B) in the sequence S5, the process shifts to the sequence S10 to determine whether (XZ) is the detection reference value (B) or more. Judgment is made. Then, when it is equal to or larger than the detection reference value (B), the sequence proceeds to the sequence S11 and the constant (C) is set to "1". After that, it is the same as the above case. On the other hand, when it is less than the detection reference value (B), the process proceeds to sequence S12, and it is determined whether (X-Y) is the detection reference value (A) or more. Then, if it is equal to or higher than the detection reference value (A), the sequence proceeds to a sequence S13 and the constant (C) is set to "3". After that, it is the same as the above case. On the other hand, when it is less than the detection reference value (A), the process proceeds to sequence S14, and it is determined whether (XZ) is equal to or more than the detection reference value (A). If it is equal to or higher than the detection reference value (A), the process proceeds to sequence S15 and the constant (C) is set.
Is set to "3". After that, it is the same as the above case. On the other hand, when it is less than the detection reference value (A),
The process moves to sequence S16, and the constant (C) is set to "0". Then, it is judged to be normal (sequence S
17) and returns to the sequence S1.

On the other hand, in the above-described sequence S8, the constant (C) is set to (C + 1), and the process proceeds to sequence S19. In sequence S19, it is determined whether or not the value of (C) of the other machine is "0", and if so, the process proceeds to sequence S20 and is determined to be normal. On the other hand, if not, the process proceeds to sequence S21, and it is determined whether or not the value of (C) of the other machine is "2", and if so, the process proceeds to sequence S22. Migrate and determine normal. On the other hand, if not, the process proceeds to sequence S23, and it is determined whether or not the value of (C) of the other machine is "4", and if so, the sequence proceeds to sequence S24. Migrate and determine normal. On the other hand, if not, the process proceeds to sequence S25, and it is determined whether or not the value of (C) of the other machine is "1", and if so, the sequence proceeds to sequence S26. After shifting, it is determined to be abnormal and the operation is stopped (sequence S27). On the other hand, if not, the process proceeds to sequence S28, and it is determined whether or not the value of (C) of the other machine is "3", and if so, the sequence proceeds to sequence S29. After shifting, it is judged to be abnormal and the machine is stopped (sequence S30).

As described above, by monitoring the difference in the rotational speed of the front roller 9 and the operation state of the fishing machine, the line clogging of the fishing line 5 can be detected. It is possible to promptly take appropriate measures against.

The present invention is not limited to the above embodiments. In each of the above-mentioned embodiments, a squid fishing machine is described as an example, but it may be applied to other fishing hoisting devices.
Further, as a means for detecting the rotation speed of the guide roller,
Other than the illustrated ones, any known detection means can be applied. Further, the rotation speed of the front roller 9 is monitored and how to process it is arbitrary. For example, the difference may be calculated by comparing with the set rotation speed of the front roller 9. The flow charts shown in FIGS. 5 and 6 are applied not only when the yarn is caught, but also when the yarn is dislocated. Further, although the winding drum is an elliptical drum in the above embodiment, it may be a circular drum and the shape of the drum is arbitrary.

The present specification (including claims)
In the above, when the term "line detachment" of the fishing line is referred to, not only when the fishing line is disengaged from the guide roller, but also when the fishing line is a front roller 9 as a guide roller, as indicated by a chain double-dashed line in FIG.
It is also included in the case where it is in contact with, but is detached from the winding reel of the winding drum 3 and wound around the drum shaft. Kashi,
This is because in this case as well as when the fishing line comes off the guide roller, the rotation speed of the guide roller sharply decreases. In the past, fishing lines were wound around the drum shaft in multiple layers,
Sometimes he wouldn't even notice until the machine couldn't operate.
