DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a jerk generating device for an automatic squid fishing machine, and more particularly, a jerk cam is provided on an operating shaft that interlocks with the rotating shaft of a fishing line winding drum, and a cam follower operates according to the jerk cam. This invention relates to the improvement of a shackle generator that applies a shaky action to the fishing line by changing the rotational speed of the prime mover (drive motor) according to the following conditions. It is an object of the present invention to provide a shackle generating device which can be generated as desired, has a simple structure, and is easy to operate.

An embodiment of the present invention will be described below with reference to the drawings.

In Fig. 1, the drive motor of the IVi automatic squid machine, 2
4 is the output shaft of the speed reducer 3; 5 is the fishing line winding drum rotating shaft; this fishing line winding drum same rotation shaft 5 is the output shaft of the speed reducing device 3 4, and a large sprocket 8 fixed to the rotating shaft 5 via an overload absorbing multi-disc clutch 7.
The chain 9 rotates between these sprockets 6 and 8, and the rotation of the fishing line winding drum rotating shaft 5 is transmitted to the operating shaft 10 by another chain sprocket 914. . That is, as shown in FIG. 2, a small sprocket 1 is attached to the rotating shaft 5 of the fishing line winding drum.
1 is fixed, and a large sprocket 1 is attached to one end of the 1 operating shaft 10.
2 are fixed and these subrokets) 11.12
Chain 13 was hooked and turned.

The fishing line winding drum rotating shaft 5 is operatively connected to the operating shaft 10 by the chain sprocket mechanism 11, 12, 13. The rotating shaft 5 and the operating shaft 10 are rotatably supported by a casing 14 of the squid fishing machine.

Reference numeral 15 denotes a jerk generator, which includes rod-shaped jerk cams 16 and 17 that are removably disposed on the outer surface of the sprocket 12 on the operating shaft 10 side in the radial direction of the sprocket 120, and a jerk generator located near the sprocket 12 on the operating shaft side. A cam follower 18 that is provided and operates in accordance with engagement with the Shakuri cam 16 and 17, a limit switch 19 as a switch means that controls ON and OFF operations by the operation of this cam follower 18, and this limit switch 19.
It is comprised of a volume conversion mechanism (not shown) that operates only when is ON to change the rotational speed of the drive motor 1. The Shakuri cams 16 and 17 are each formed into a flat plate shape with a rectangular cross section.
6 is connected to the sprocket 12 by a screw 22 screwed into the screw hole 21 of the sprocket 12 from the cam 16 (] a hole 2G.
However, the tightening is removably fixed, and is usually a fixed cam. The other shackle cam 17 is normally a position change cam, and is connected to the through hole 2 of the sprocket 12.
It is fixed to the sprocket 12 by a setscrew 25 screwed into the threaded hole 24 of the shackle cam 17, and a positioning pin 26 protruding from the end face of the shackle cam 17 is attached to one of the shackle cams (fixed cams). )16
It is fixed at a predetermined position with respect to the fixed cam 16 by fitting it into a vertical hole 27 or a horizontal hole 2B provided at the end of the cam 16. A plurality of through holes 23 marked by -h are arranged at predetermined intervals in the circumferential direction of the sprocket 12, so that the mounting position of the jerk cam 17 can be changed in various ways. The limit switch 19 is integrally combined with the cam follower 18, and when the cam follower 18 is engaged with the shakuri cam 16 or 17, the switch is turned on, and when it is not engaged, the switch is turned off, and this limit switch is turned on. The switch 19 is installed on a movable base 29 which is movable in the radial direction of the sprocket 12, and this movable base 29 has one guide hole 30, 30 as shown in FIGS. The holes 3o, 3o are slidably fitted into the support columns 33, 33 of the Yoshikoro, which are erected on the base frame 31 fixed to the casing 14 and interconnected by the support frame 32, and are fitted in a movable base 29. are fixed by fixing screws 34 at predetermined positions on the columns 33, 33.

Next, to explain the operation of the above-mentioned jerk generator 15, FIGS.
Depending on how this arrangement is selected, various patterns of shackle can be obtained. In this case, it is assumed that the cam follower 18 is always fixed at a fixed position. First, FIG. 5 1 shows a state in which only seven shackle cams 16 are attached to the sprocket 12, and the other shackle cams 17 are removed. In this case.

As the actuating shaft 10 is rotated and its sprocket 12 rotates, the cam follower 18 in place engages the jerk cam 16 only 7 times per revolution (3 o'clock) of the sprocket 12, and this engagement causes the limit switch 19
When the switch is turned on, the rotational speed of the drive motor 1 is changed from the preset speed (base speed) Vo to the faster speed [Vs) K by the volume conversion mechanism, and When the connection with the shakuri cam 16 is released, the limit switch 19 is turned off and the drive motor 1 returns to its original speed. The shackle pattern obtained in this case is shown at 1 in FIG.

Figure 5 ■ shows Shakuri cam 16 in the state of No. 511 JI.
In this case, the cam follower 1B engages with either the sharp cam 16 or 17 every half rotation of the sprocket 12. The shackle pattern at that time is shown by ■ in Fig. 6. In addition, Fig. 5 (■) shows a case in which the position of the Shakuri cam 17 on the sprocket 12 is changed from the 51st NH position to a position rotated by 20 degrees, and the circumferential distance between the Shakuri cams 16 and 17 is changed. In this case, the cam follower 18 rotates the cam 16.1 at the 200° rotation position and the next 20° rotation position of the sprocket 12.
7, and the shackle pattern at that time is shown by ■ in FIG. Furthermore, Fig. 5 (■) is an example in which the case of Fig. 5 (■) and the case of Fig. 5 (■) are combined. 2 Shakuri cams 1 in the position
7.17 is arranged, and FIG.
7.17 are arranged in a cross shape, that is, on seven fixed cams 16.
hj L, , i position change cams 17, 17, 17 are arranged at equal intervals from each other in the circumferential direction.

In the above-described operation, the cam 7 lower 18 was fixed at a fixed position and the number and arrangement of the cams were changed to produce various patterns of shackle action, but the number and arrangement of the cams were kept constant. The jerk pattern can also be changed in various ways by appropriately moving the cam 7 follower 18 in the radial direction of the sprocket 12. Of course, if both methods are used in combination, even more various patterns of shakiri can be performed. FIG. 7 illustrates a case in which the cam followers 16 and 17 are arranged facing each other on the sprocket 12, and the cam follower 18 is moved in the radial direction of the sprocket 12 while this arrangement is maintained. In addition, cam follower 18
The movable base 29 is slid along the columns 33, 33 and fixed at a desired position by the fixing screws 34. Now, if the cam follower 18 is set at the position A shown by the imaginary line in FIG. 7, the resulting jerking pattern will be as shown by A in FIG. If the cam follower 18 is set at a position closer to the center of the sprocket 12 from the position A in Fig. 7, that is, at the mouth position in the same figure, the radius of rotation will be shorter than in the position A above. As a result, the engagement time of the cam 7 lower 18 with the shackle cam 16, 17 becomes longer, while the non-engagement time becomes shorter, so that the shank pattern in this case becomes the mouth state shown in FIG. In addition, the position where the cam follower 18 is moved in the outward radial direction of the sprocket 12 (in Fig. 7, the engagement time with the cam 16 and 17 becomes shorter, but the disengagement time becomes longer, resulting in a jerky pattern) becomes the state C in FIG.

In addition, in the above operation, we have explained the case where the polyurethane conversion mechanism is set to instantaneously switch the drive motor 1, which is rotating at a slow speed, to a high speed. It is also possible to create a jerking action by setting the porium conversion mechanism to momentarily switch the drive motor 1 to a slow speed. In this case, the jerking cams 16 and 17 can be arranged as shown in Figure 5, for example. If the cam follower 18 is placed as close to the center of the sprocket 12 as possible, the shackle pattern will be as shown by X in FIG. Moreover, the pattern Y shown in FIG. 9 is a special example, and the pattern Y shown in FIG.
17 is arranged as shown in FIG. 5, and the cam follower 18 is set at a position near the center of the sprocket 12.

As explained above, the jerk generating device of the present invention includes a rod-shaped jerk cam that is removably disposed on the side surface of the sprocket on the operating shaft side in the radial direction of the sprocket, and the jerk cam that is driven by the jerk cam near the sprocket. The Shakuri cam is equipped with a cam follower and a switch means that operates according to the operation of the 7-olower, and this switch means is connected to a speed conversion mechanism that changes the rotation of the drive motor by the operation of the switch means. By changing the number of shake cams, it is possible to perform various different patterns of shaking action simply by changing the arrangement of the shake cams.In particular, by attaching the shake cams to the sprocket with screw members, the operation of attaching and detaching the shake cams is simple and easy. Become. Furthermore, since the jerk generating device of the present invention is arranged such that the cam follower and the switch means are movable in the radial direction of the sprocket, in addition to changing the number or arrangement of the jerk cams, the position of the switch means in the radial direction of the sprocket can be changed. Furthermore, it is possible to produce a wide variety of patterns of jerking effects, and compared to conventional single-pattern jerking generating devices, this invention can be said to be a very revolutionary invention.
