Description: TECHNICAL FIELD The present invention relates to an ultrasonic welding apparatus for thread-shaped synthetic resin such as nylon monofilament, and is particularly used for welding threads for fixing shellfish for aquaculture. It is suitable.

[Conventional technology]

The fusion of the synthetic resin using the ultrasonic fusion device has the advantages that an adhesive is not required, the drying time is not required, and the strength and the finished appearance are excellent. Such fusion of synthetic resin is widely performed without being limited to the production of industrial products, and the ultrasonic fusion device required for fusion of a string for packing for packing and fusion of an ink ribbon is required. It is used (for example, see JP-A-63-132031).

Further, as one of the shapes of the synthetic resin, there is a thread-shaped one such as nylon monofilament, and such a thread-shaped synthetic resin is used for fishing nets, fishing lines and the like. Then, as an apparatus for ultrasonically fusing a thread-shaped synthetic resin, the applicant of the present application has previously described in the specification and drawings of Japanese Patent Application No. 1-269177, and describes a pedestal facing an ultrasonic vibrating section. A device is proposed in which a groove is formed in a part and ultrasonic fusion is performed while holding a thread-shaped synthetic resin in the groove.

[Problems to be Solved by the Invention]

By the way, in aquaculture of scallops, a hole is formed in a part of the shell of a juvenile shell, and a thread-like synthetic resin is passed through the hole and suspended in the sea. When suspending juveniles on a thread, it is necessary to arrange juveniles of scallops at regular intervals. Conventionally, the thread is tied at regular intervals to fix the shells. Was being advanced.

However, in the case where the operation of tying such a thread is manually performed, it takes a long time to cultivate a huge number of scallops, and the operation requires skill.

On the other hand, by ultrasonically fusing the stopper to the thread-shaped synthetic resin using the ultrasonic fusing device, it is possible to greatly improve the workability. However, it is difficult to improve the efficiency of the entire work with a device having only a mechanism for fusing.

Therefore, in view of the above-mentioned technical problems, the present invention improves the previously proposed device for ultrasonically fusing a filamentous synthetic resin, and an object of the present invention is to provide an ultrasonic welding device in which efficient work and the like are realized. And

[Means for Solving the Problems]

In order to achieve the above-mentioned object, the ultrasonic fusing device of the present invention, a base, an ultrasonic vibrating section having a tapered tip end portion fixed to the base, with respect to the base. A pedestal that is movably mounted and is held in a groove provided on a surface facing the ultrasonic vibrating portion so that the synthetic resin is crimped to the ultrasonic vibrating portion during fusion bonding, and It has a feeding mechanism portion for feeding the filamentous synthetic resin into the groove, and a cutting mechanism portion for cutting the filamentous synthetic resin fed from the feeding mechanism portion into a required length.

Here, the groove provided in the pedestal may have a structure including a synthetic resin holding groove for holding the cut filamentous synthetic resin and an opening groove opened for crimping the ultrasonic vibrating portion.
The moving direction of the pedestal can be, for example, a horizontal direction. Further, the base of the ultrasonic welding device of the present invention may be provided with a handle rotatable about an axis, and a first cam and a second cam fixed to the handle may be provided. It is possible. Further, the feed mechanism section may have a structure having a feed motor.

Then, in the ultrasonic fusing device of the present invention, the cradle moves with respect to the ultrasonic vibrating unit after the feeding operation of the filamentous synthetic resin of the feeding mechanism section and the cutting operation of the filamentous synthetic resin of the cutting mechanism section. It is characterized in that the filamentous synthetic resin is fused by being operated. Then, in order to perform such a continuous operation, in the case where the rotatable handle is provided and the first and second cams are provided, the cutting operation of the cutting mechanism portion is performed by the rotation operation of the first cam. The rotation of the second cam allows the pedestal to move to the ultrasonic vibrating section. Further, in the case where the feed mechanism is provided with a feed motor, the feed motor can be operated by a switch that is opened and closed by turning the handle.

[Action]

In the ultrasonic fusing device of the present invention, the pedestal is moved with respect to the base instead of the ultrasonic vibrating section, and the fusing work of the filamentous synthetic resin is advanced. In general, the ultrasonic vibrating unit has a larger weight and size than the pedestal, and a signal is also supplied. Therefore, by adopting a structure in which the pedestal side is moved, work efficiency is significantly improved. Further, in the ultrasonic welding device of the present invention, after the feeding operation of the feeding mechanism section and the cutting operation of the cutting mechanism section, the ultrasonic welding is performed by moving the pedestal. Therefore,
In the operation of fusing the stoppers of the thread-shaped synthetic resin at regular intervals, the cut pieces of the thread-shaped synthetic resin can be continuously fused, and an efficient operation can be realized.

Then, a feeding mechanism portion 6 for feeding the nylon monofilament is fixedly provided on the base 2 on the side portion of the cutting mechanism portion 5. The feed mechanism unit 6 has a feed motor 61, and has a structure in which a predetermined amount of nylon monofilament is fed to the cutting mechanism unit 5 by its rotation operation. The handle 7 is attached so as to rotate around a shaft 71 fixed to the base 2. The handle 7 mechanically controls the cutter 51 of the cutting mechanism unit 7 and the position of the cradle 4 by using the cams 73 and 74, and also electrically controls the feed motor 61. ing.

Structure of Ultrasonic Vibration Unit The ultrasonic vibration unit 3 has a function of generating ultrasonic vibration from a high frequency, and the nylon monofilament is fused by the ultrasonic vibration. As shown in FIGS. 1 to 3, the ultrasonic vibrating section 3 includes a vibrator 31 and a vibrator horn 33.
The transducer horn 33 is supported by the horn support 32. The vibrator 31 generates ultrasonic vibration by a high frequency signal from a high frequency transmitter (not shown), and has a substantially cylindrical shape. This oscillator 3
A vibrator horn 33 is continuously provided at position 1, and the vibrator horn 33 amplifies ultrasonic vibration from the vibrator 31.
The base end side of the vibrator horn 33 is fitted and supported by the horn support base 32 which stands upright on the base base 2.
The vibrator horn 33 is fixedly supported on the base 2. The tip portion 34 of the vibrator horn 33 is tapered, and the tip portion 34a thereof is projected in a flat plate shape like the tip of a minus driver. A groove corresponding to the nylon monofilament may be provided in the tip portion 34a. The thickness of the most advanced portion 34a is
The width can be set depending on the diameter of the nylon monofilament to be fused, and is narrower than the width of the groove portion 41 of the pedestal 4. In this way, the tip portion 34 of the vibrator horn 33 is
Since the taper is tapered into a flat plate shape, the nylon monofilament, which is a thread-like synthetic resin, can be effectively pressure-bonded from the longitudinal direction.

Structure of the pedestal Next, the pedestal 4 will be described with reference to FIGS. 1 to 3 and 4. The pedestal 4 is made of stainless steel, and the tip portion 42 thereof faces the ultrasonic vibration portion 3. A groove 41 is formed in the tip 42 as shown in FIG. Specifically, the groove portion 41 is a holding groove 44 for holding the nylon monofilament inserted in the Y direction in the figure, and an opening groove 4 for guiding the tip end portion 34 of the vibrator horn 33 to be crimped.
3 and 3. The holding groove 44 is a through-hole-shaped groove corresponding to the diameter of the nylon monofilament, and may have a diameter about 0.1 mm larger than the diameter of the nylon monofilament.
The opening groove 43 is a notch extending straight from the surface of the pedestal 4 facing the ultrasonic vibrating portion 3 to the holding groove 44, and the vibrator horn 3 is tapered in a flat plate shape.
It has such a width that the leading edge part 34a of the third part can be inserted. Both the holding groove 44 and the opening groove 43 are formed over the width y ₁ of the tip portion 42 of the pedestal 4. The surface of the tip portion 42 facing the ultrasonic vibrating portion 3 has a structure in which the lower jaw portion 45 of the opening groove 43 projects more than the upper jaw portion 46. Therefore, when the other nylon monofilament to be fused to the nylon monofilament held in the holding groove 44 is interposed in the opening groove 43, the one nylon monofilament is opened from the upper side of the device while being applied to the lower jaw portion 45. It can be easily pushed into the groove 43, and when the nylon monofilament is pushed into the opening groove 43, the pedestal 4 is pressed against the ultrasonic vibrating section 3, whereby ultrasonic welding is performed.

The pedestal 4 having such a tip portion 42 is provided on the base 2 as follows.
It can be moved in the X direction of FIG. 1, that is, in the longitudinal direction of the ultrasonic vibration part 3. On the handle 7 side of the pedestal 4, a contact portion 47 that is pressed by the pedestal pressing rubber 77 attached to the pedestal pressing shaft 76 is formed. The contact portion 47 is integrated with the tip portion 42, and has a structure in which two guide bars 48, 48 are provided above and below the contact portion 47. One end of each of the pair of guide rods 48, 48 is fixed to the base projecting portion 21 projecting from the base 2, and the X direction is the longitudinal direction in the drawing. The movement direction is limited only to the X direction. Further, the pedestal 4 has a coil spring 49 attached by suspending one end from a pin 50 protruding from the pedestal 4, and the other end of the coil spring 49 is a pin protruding from the base projecting portion 21. 22
Are hung up on. Therefore, when the pressing operation of the pedestal pressing rubber 77 is completed, the cradle 4 is moved by the coil spring 49.
Will be pushed back to the original position. Although not shown, the coil spring 49 is also attached to an inner portion of the base 2, and the pair of coil springs 49 arranged above and below the base 4 return the base 4. Will be done.

Structure of the cutting mechanism section The cutting mechanism section 5 is a mechanism section for cutting the nylon monofilament into a predetermined length by the function of the cutter 51. When the cut nylon monofilament is applied to scallop aquaculture described later, For example, it is used as a stopper. FIG. 5 is a perspective view of the cutting mechanism section 5,
A cutter base 52 is attached and fixed on the base 2. A shaft 53 is provided on the cutter base 52 so as to project toward the receiving base 4, and a substantially rectangular cutter mounting plate 54 is rotatably mounted on the shaft 53. A cutter 5 having a blade 51a for cutting a nylon monofilament on one end side of the cutter mounting plate 54
1 is fixedly attached. The blade 51a is attached to the cutter attachment plate 54 so that it can be cut downward, and can cut the nylon monofilament inserted through the through hole 55 provided in a part of the cutter base 52. A roller 56 is attached to the other end of the cutter attachment plate 54. The roller 56 is rotatable with respect to the shaft 57 and has a bearing. This roller 56 is provided with a cutter pushing shaft 75 as described later.
The lower half of it abuts the cutter pushing shaft 75.
Interlock with the operation of.

For example, when the cutter pushing shaft 75 does not sufficiently push the roller 56, the position of the roller 56 is held at a low position, and the blade 51a of the cutter 51 is set at a position higher than the through hole 55. As a result, the nylon monofilament can be sent to the pedestal 4 through the through hole 55. On the contrary, when the cutter pushing shaft 75 pushes the roller 56 sufficiently, the position of the roller 56 is held at a high position, and when the position of the roller 56 becomes high, the cutter mounting plate 54 causes the shaft 53 to move. The blade 51a of the cutter 51 becomes lower than the position of the through hole 55 by rotating around. As a result, the nylon monofilament protruding from the through hole 55 is cut by the blade 51a of the cutter 51 that moves from a high position to a low position according to the rotation of the cutter mounting plate 54.

The upper portion 58 of the cutter mounting plate 54 that rotates in this way
Comes into contact with the tip 59a of the leaf spring 59. The base end portion 59b of the leaf spring 59 is fixed to the upper portion of the base projecting portion 21, and the leaf spring 59 causes the roller 57 of the cutting mechanism portion 5 to always act on the cutter pushing shaft 75.
Will be abutted against.

Structure of Feeding Mechanism Section The feeding mechanism section 6 is a mechanism section for feeding the nylon monofilament to the holding groove 44 of the pedestal 4 via the cutting mechanism section 5, and the feeding motor 61 drives the nylon monofilament. As shown in FIG. 6, the feed motor 61 is mounted on one surface of a mounting frame 62 having a substantially L-shaped cross section, and its rotation shaft 63 projects from the other surface of the mounting frame 62. A rubber roller 64 is attached to the rotating shaft 63 on the other surface side. This rubber roller 64 is rotated by the rotation drive of the feed motor 61, and functions to feed the nylon monofilament in the Y direction in the figure by the friction of the surface thereof. Above the rubber roller 64, a resin-made pressing roller 65 for sandwiching the nylon monofilament in pairs with the rubber roller 64 is rotatably attached to a pressing-roller support fitting 66. . Therefore, the nylon monofilament is sandwiched between the pressing roller 65 and the feeding rubber roller 64 and is fed to the cutting mechanism section 5 side. The pressing roller 65 is provided with a groove 65a on its peripheral surface, and the nylon monofilament has a groove 6a.
By the guide of 5a, it is reliably sent to the through hole 55 of the cutting mechanism section 5. The pressing roller support fitting 66 is made of a plate material,
It is processed into a substantially V shape so as to avoid the rubber roller 64. One end of the pressing roller support fitting 66 is supported so as to be rotatable about the hinge pin 67, and the other end of the pressing roller support fitting 66 has a coil spring 69 suspended from a pin 68. The other end of the coil spring 69 is suspended on the pin 70 protruding from the other surface of the mounting frame 62. Therefore, the pressing roller 65 is attached to the rubber roller 64 side together with the pressing roller support fitting 66 by the tension of the coil spring 69. Energized.

Handle and Mechanism Around It Next, the handle 7 and a mechanism around it will be described.
As shown in FIG. 3, the handle 7 is a long rod-shaped member and is configured to be rotatable around a shaft 71 fixed to the base 2. The handle 7 has a handle portion 72 for the operator to manually support, and the handle 7 is operated by the operator changing the position of the handle portion 72 with respect to the shaft 71. A first cam 73 and a second cam 74 are mounted coaxially with the shaft 71 of the handle 7. The first cam 73 is for activating the cutting mechanism section 5, and the second cam 74 is for moving the pedestal 4. Each of the cams 73, 74 has a disk shape, and a part thereof is cut out so as to draw a string. Then, the cutter pushing shaft 75 contacts the first cam 73, and the pedestal pushing shaft 76 contacts the second cam 74. For example, when the position of the handle 7 is at the origin, the cutter pushing shaft 75 abuts on the notched portion of the first cam 73, and at the same time, the pedestal pushing shaft 7
6 contacts the notched portion of the second cam 74. Since the outer diameter of each cam is reduced in these notched portions, the pushing amounts of the cutter pushing shaft 75 and the pedestal pushing shaft 76 are reduced. Therefore, the cutter 51 is kept raised and the pedestal 4 is not pressed against the ultrasonic vibrating portion 3 side. When the handle 7 is rotated, the cams 73 and 74 rotate, which causes the shafts 75 and 76 to reciprocate, cutting the nylon monofilament and moving the pedestal 4. This will be described later with reference to FIGS. 7 to 9. A coil spring 78 is attached to the upper portion of the first cam 73. The coil spring 78 has one end suspended on a pin 79 fixed to the shaft 71, and the other end suspended on the cutter pushing shaft 75.
It is suspended from the pin 80 protruding from the. Therefore, the tension of the coil spring 78 presses the cutter pushing shaft 75 against the peripheral surface of the first cam 73. The handle 7 is a rotation control stopper 8 provided on the base 2.
The rotation range is limited by 1, 82. These rotation control stoppers 81 and 82 have screws 83 and
Since 83 is attached, fine adjustment of the turning range is possible. A first sensor switch 91 and a second sensor switch 92 are provided on the surface of the base 2 in a region where the handle 7 can move. These sensor switches 91 and 92 are closed in a non-contact manner by a magnet 93 attached to the back surface of the handle 7. The feed motor 61 of the feed mechanism unit 6 is driven by the first sensor switch 91. By the second sensor switch 92,
A high frequency signal is supplied to the vibrator 31 of the ultrasonic vibration unit 3. Therefore, the operator can perform the fusion work of the nylon monofilament only by operating the handle 7.
Particularly, it is advantageous when the fusion is continuously performed.

Fusing Work Next, the fusing work by the ultrasonic fusing device 1 of the present embodiment will be described.

First, the nylon monofilament to be cut and fused is inserted into the through hole 55 of the cutting mechanism portion 5, and the nylon monofilament is sandwiched between the rubber roller 64 of the feeding mechanism portion 6 and the contact point of the pressing roller 65 to be supported. To be done. In this device, nylon monofilaments are ultrasonically fused to each other. Here, the nylon monofilament to be cut has a relatively large diameter, and even if the diameter is different, ultrasonic fusion is surely performed. Further, it is not limited to fusion of different diameters, and ultrasonic fusion of nylon monofilaments having the same diameter is also possible. The other nylon monofilament is arranged in the opening groove 43 of the groove portion 41 of the pedestal 4. The other nylon monofilament can be easily arranged in the opening groove 43 due to the difference in the protrusion amount between the lower jaw portion 45 and the upper jaw portion 46 of the pedestal 4.

At this stage, the handle 7 is placed at the origin, that is, the position in contact with the rotation control stopper 82. At this origin position,
As shown in FIG. 7, the cutter pushing shaft 75 and the pedestal pushing shaft 76 which are held by the base projecting portion 21 and slidable only in the X direction are both the first cam 73 and the second cam 74. Abutting on the notched part of the blade 51 of the cutter 51
a cuts the nylon monofilament, or the pedestal 4
Does not move toward the ultrasonic vibrating section 3. Then, at or near this origin, the magnetic field from the magnet 93 attached to the back surface of the handle 7 is detected by the first sensor switch 91 in a non-contact manner. As a result, the feed motor 61 is driven. The rubber roller 64 is rotated by driving the feed motor 61. According to the rotation, the nylon monofilament fed to the through hole 55 is fed so as to be inserted into the holding groove 44 of the pedestal 4 while being sandwiched between the rubber roller 64 and the pressing roller 65. And about the width y of the cradle 4
_{When the} nylon monofilament is fed by a predetermined amount of about _1, the driving of the feed motor 61 is stopped. The feed amount of the nylon monofilament by the feed motor 61 can be adjusted by a controller or the like.

Next, the handle 7 is rotated counterclockwise around the shaft 71. Then, the first cam 73 rotates as the handle 7 rotates, and as shown in FIG. 8, the diameter from the shaft 71 to the contact point of the cutter pushing shaft 75 increases. At this stage, the pedestal push shaft 7 that contacts the second cam 74
6 is not pushed in yet.

By such an operation of the first cam 73, the cutter pushing shaft 75 extends the coil spring 78, and
Pushed in the direction. Then, the other end of the cutter pushing shaft 75 overcomes the downward urging force of the leaf spring 59 to push up the roller 56, and the cutter mounting plate 54 is rotated about the shaft 53. Since the cutter 51 is fixed to the cutter mounting plate 54, when the cutter pushing shaft 75 is sufficiently pushed, the blade 51a cuts the nylon monofilament protruding from the through hole 55. as a result,
The cut nylon monofilament remains inside the holding groove 44 of the pedestal 4.

Next, after cutting the nylon monofilament, the handle 7 is further rotated counterclockwise, so that the second cam 74 pushes the pedestal pushing shaft 76 in the X direction in the figure, as shown in FIG. The second of this pedestal pushing shaft 76
A pedestal pressing rubber 77 is attached to the opposite end of the cam 74, and the pedestal pressing rubber 77 pushes the contact portion 47 of the pedestal 4 in the X direction. As a result, the entire pedestal 4 is pushed in the X direction along the guide rods 48, 48 while receiving the elastic force of the pair of upper and lower coil springs 49.

As the pedestal 4 is pushed in the X direction in this manner, the tip end portion 34a of the transducer horn enters the opening groove 43 of the tip portion 42 of the pedestal 4. In the opening groove 43, the tip portion 34a contacts the other nylon monofilament that has not been cut, and the cradle 4 is pushed in the X direction as it is, so that the other nylon monofilament and the cutter 51 have already been cut.
The nylon monofilament that is cut by and is held in the holding groove 44 is pressed.

The two nylon monofilaments to be fused are grooved 41
When pressed inside, the handle 7 reaches the second sensor switch 92. Then, the magnet 93 attached to the back surface side of the handle 7 closes the second sensor switch 92. As a result, a high-frequency signal is supplied from a high-frequency transmitter (not shown) to the vibrator 31, ultrasonic vibration is generated, the ultrasonic vibration is amplified by the vibrator horn 33, and is transmitted to the tip portion 34. Then, due to the ultrasonic vibration, the nylon monofilament in the groove 41 of the pedestal 4 is fused in a short time.

Then, by rotating the handle 7 clockwise to return it to the origin, the first cam 73 and the second cam 74 are returned to the positions shown in FIG. 7, and the pedestal 4 and the pedestal pusher are pushed. The shaft 76 is returned to its original position by the pulling force of the coil spring 49, the cutter 51 by the biasing force of the leaf spring 59, and the cutter pushing shaft 75 by the pulling force of the coil spring 78. Then, again by the operation of the handle 7, the ultrasonic fusion of the same nylon monofilament is continuously performed.

Application of Scallop Culture to Aquaculture As described above, the ultrasonic fusing device of this embodiment capable of continuous fusing work is particularly suitable for aquaculture of scallops.

For example, a scallop is a juvenile 1 as shown in FIG.
It is necessary to fix a plurality of 00s to the nylon monofilament 101.

Therefore, by performing the above-mentioned continuous ultrasonic fusion work,
As shown in FIG. 11, a nylon monofilament 1 inserted through a hole 102 provided in the ear portion of the juvenile shell 100.
No. 01, a thick nylon monofilament 103 as a stopper can be fused. The nylon monofilament 103 is cut into short pieces, and the fused portion has a diameter larger than the diameter of the hole 102, so that the juvenile shell 100 can be hung on the nylon monofilament 101 at predetermined intervals. By using the ultrasonic fusing device of the present embodiment, continuous ultrasonic fusing work is realized, and quick stopper fusing is performed without requiring special skill, and its labor is significantly increased. Saves labor. In addition, such work is often performed on a ship or in a relatively small work space. In the ultrasonic welding device of this embodiment, the transducer horn 33 is placed horizontally and the ultrasonic vibrating section 3 is used. Since the height of is also suppressed, it contributes to the improvement of work efficiency. Further, also when visually observing the fused portion, the ultrasonic vibrating portion 3 having the horizontal longitudinal direction is advantageous.

〔The invention's effect〕

In the ultrasonic fusing device of the present invention, the relatively small and lightweight pedestal moves relative to the base to advance the fusing work of the filamentous synthetic resin. Therefore, working efficiency is significantly improved.
Further, in the ultrasonic welding device of the present invention, after the feeding operation of the feeding mechanism section and the cutting operation of the cutting mechanism section, the ultrasonic welding is performed by moving the pedestal. Therefore, in the work of fusing the stoppers of the thread-shaped synthetic resin at regular intervals, the cut pieces of the thread-shaped synthetic resin can be continuously fused, and an efficient operation can be realized. Further, by fixing the first and second cams to the handle, ultrasonic fusion is realized in conjunction with the rotating operation of the handle, and the workability thereof is greatly improved.
