  By the way, as environmental problems become active in recent years, binding tapes for horticultural binding machines are favorably used for those that are photodegradable or biodegradable.

  However, as described above, the conventional horticultural binding machine binds the binding tape with staples. Since the staples are made of steel or the like, even if the binding tape is disassembled, the staples are not disassembled and stay in the soil such as fields.

  The present invention is an attempt to solve such a problem, and an object thereof is to provide a horticultural tying machine having little adverse effect on soil.

  The present invention comprises a main handle having a tape delivery portion at the tip portion and a lifting arm having a tape gripping mechanism at the tip portion and rotatably disposed on the main handle, and a binding tape between the tip portions. In a horticultural binding machine that accommodates a bundled body between a main handle and a lifting arm that spans and binds both ends of a binding tape that surrounds the bundled body, the main handle or the tip of the lifting arm Connected to the ultrasonic vibration section provided on one side of the ultrasonic vibration section provided on one side, the anvil provided on the other end of the lift arm or the front end of the main handle and disposed at a position facing the front end of the ultrasonic vibration section And an oscillation device that transmits a high-frequency electrical signal to the ultrasonic vibration unit, and an operation switch for causing the oscillation device to transmit the electrical signal, the ultrasonic vibration unit and the anvil, A horticultural binding machine characterized by sandwiching both ends of a binding tape that encloses the object to be bound and vibrating the ultrasonic vibration part in this state to weld the binding tape at that part. .

  According to this structure, the binding tape surrounding the periphery of the binding object is bound at both ends by ultrasonic welding. That is, the horticultural binding machine of the present invention can bind the objects to be bound using only the binding tape without stapling.

  The horticultural binding machine of the present invention can weld a thermoplastic binding tape. Since most of the binding tapes for horticultural binding machines are made of thermoplastic resin, the horticultural binding machine of the present invention can suitably weld most of the conventional binding tapes. If it is a thermoplastic binding tape, the binding tape can be bound with the same force as when staples are used.

  In the horticultural binding machine of the present invention, it is desirable that the binding tape is biodegradable or photodegradable. In such a case, the binding tape can be assimilated into the soil or the like when the binding tape is peeled off from the binding object. As described above, since the horticultural binding machine of the present invention does not use staples or the like, no residue remains without being decomposed.

  In the horticultural binding machine of the present invention, it is desirable that the oscillation device is not assembled integrally with the main handle, the lifting arm, or the like, but is provided separately and connected to the binding machine main body via an electric cable. This is because the existing oscillation device is relatively heavy, and if it is integrated with the main handle or the like, the workability is likely to deteriorate. In addition, since an ultrasonic vibration part and an anvil are lightweight, there is no possibility that workability | operativity will fall even if it arrange | positions in the conventional gardening binding machine. In addition, since the ultrasonic vibration part and anvil are small, the ultrasonic vibration part and anvil can be arranged in place of the staple magazine and clincher without changing the basic design of the conventional horticultural binding machine. Is possible. That is, this invention can utilize the basic composition of the conventional gardening binding machine 1a (refer FIG. 6) mentioned above as it is.

  The operation mechanism of the oscillation device and the operation switch is not particularly limited. For example, a contact switch that operates in a state where the handle and the arm are sandwiched is desirable. When such an operation switch is turned on, it is desirable that the oscillation device transmits a high-frequency electrical signal to the ultrasonic vibration unit for a predetermined time so that the ultrasonic vibration unit vibrates for a predetermined time.

  In the horticultural binding machine of the present invention, an anvil is disposed on the main handle, an ultrasonic vibration unit is disposed on the lifting arm, and a tape cutting blade is disposed on the tip of the main handle. A base frame, and an anvil holding frame that is held by the base frame so that the anvil disposed at the tip portion can be moved toward and away from the tape cutting blade. When the anvil is urged away from the tape cutting blade and the both ends of the binding tape are sandwiched between the ultrasonic vibration part and the anvil, when the ultrasonic vibration part is strongly pressed against the anvil, the anvil holding frame is urged. In contrast, a configuration is proposed in which the anvil is moved in the direction of approaching the tape cutting blade and the binding tape is cut by the tape cutting blade in the vicinity of the clamping portion.

  In such a configuration, after the binding tape is sandwiched between the ultrasonic vibration part and the anvil, the binding tape can be cut by the sandwiching operation and a series of movements. That is, according to this configuration, the binding tape can be cut at an appropriate timing by a simple operation.

  In the configuration including the base frame and the anvil holding frame, the operation switch is disposed on one of the base frame and the anvil holding frame, and the anvil holding frame moves in a direction to bring the anvil closer to the tape cutting blade. It is proposed that the oscillation device transmit a high-frequency electrical signal to the ultrasonic vibration unit for a predetermined time when the operation switch detects the movement.

  In such a configuration, the ultrasonic vibration unit automatically vibrates in accordance with the operation of cutting the binding tape. That is, according to this configuration, it is possible to always vibrate the ultrasonic vibration unit at an appropriate timing without the operator operating the operation switch.

  As described above, according to the horticultural binding machine of the present invention, since the objects to be bound can be bound only with the binding tape without using staples or the like, there is an advantage that there is little adverse effect on the soil. Further, in the conventional configuration in which the binding tape is bound with staples, the binding tape and the staples must be separated and discarded when the binding tape is removed from the bound object. However, the present invention does not require such labor. . Further, in the conventional horticultural binding machine using staples, it takes time to replenish staples regularly. However, according to the horticultural binding machine of the present invention, such labor can be saved. Further, according to the ultrasonic welding, it is possible to realize a binding force comparable to that when binding is performed using staples. Generally, when binding with an adhesive tape, the binding force is weak and the binding work is complicated, but the present invention does not cause such a problem.

  Embodiments of the present invention will be described according to the following examples.

  FIG. 1 is a schematic view of a horticultural binding machine 1 of this embodiment. The horticultural binding machine 1 includes a binding machine main body 2 in which a main handle 5 and a lifting arm 6 are assembled, and an oscillation device 3 connected to the binding machine main body 2 via an electric cable 4.

  The binding machine body 2 is provided with an ultrasonic vibration part, an anvil and the like in place of the staple magazine and clutcher of the conventional gardening binding machine. The basic configuration is the conventional gardening binding shown in FIG. It is substantially the same as the machine 1a. In addition, the same code | symbol is attached | subjected to the part which has the same structure as the said gardening binding machine 1a. As shown in FIG. 2, the binding machine main body 2 includes a main handle 5 having a tape delivery unit 14 at a distal end portion and a tape gripping mechanism 13 at a distal end portion, and is rotatably disposed on the main handle 5. The elevating arm 6 includes an operating lever 9 having one end engaged with the main handle 5, an intermediate portion rotatably provided on the elevating arm 6, and a grip portion 15 at the other end. . The elevating arm 6 is biased by a spring 34 in a direction to separate the tip from the main handle 5, so that the elevating arm 6 and the tip of the main handle 5 approach each other when the grip 15 of the operating lever 9 is gripped. It has become.

  As shown in FIG. 2, the main handle 5 is disposed so as to be slightly tiltable up and down just below the base frame 18, which is pivotally supported by the rear portion of the base frame 18 and a metal base frame 18 that is long in the front and rear directions. And an anvil holding frame 19 made of metal that is long in the front and rear. A metal anvil 20 is fixed to the lower bottom surface on the distal end side of the anvil holding frame 19. The anvil 20 is disposed at a position facing a tip of a horn 28 described later, and the tip of the horn 28 comes into contact with the lower bottom surface of the anvil 20 when the operation lever 9 is gripped. The anvil holding frame 19 is held so as to be slightly tiltable up and down with respect to the base frame 18 and is biased downward by a spring (not shown). The lower bottom surface of the anvil 20 is strongly supported by a horn 28 described later. When pressed, the anvil holding frame 19 tilts upward against the biasing force of the spring and moves closer to the base frame 18.

  In addition, a resin-made tape guide base 7 is disposed at the upper part of the base frame 18, and a tape magazine 8 for accommodating the roll-like binding tape 10 is disposed at the rear part of the base frame 18. The bundling tape 10 pulled out from the tape magazine 8 is guided to the tape delivery part 14 at the tip of the main handle 5 through the inside of the tape guide 7. The tape delivery unit 14 is a gap on the slit formed between the base frame 18 and the tip of the anvil holding frame 19, and the binding tape 10 guided to the tape delivery unit 14 by the tape guide 7 is the main handle 5. It will be sent out from the tip of this.

  Further, a tape cutting blade 12 for cutting the binding tape 10 is provided at the distal end portion of the base frame 18. The tape cutting blade 12 is arranged so that the blade faces downward. Normally, the anvil 20 is positioned below the tape cutting blade 12, but when the anvil holding frame 19 tilts upward, the anvil 20 approaches the position immediately behind the tape cutting blade 12. According to such a configuration, the binding tape 10 held between the anvil 20 and the horn 28 can be cut immediately before the holding portion by bringing the anvil 20 close to the tape cutting blade 12 (FIG. 4F). reference).

  As shown in FIG. 3, the tape gripping mechanism 13 disposed at the distal end portion of the lifting arm 6 includes a picking plate 22 having a hook-shaped projection at the distal end, a push plate 23, a tape holding plate 24, and the like. . The picking plate 22 is pivotable back and forth, and the hook-shaped protrusion is urged to a rear gripping position α that contacts the tape holding plate 24 and is moved forward of the tape holding plate 24 by a cam mechanism (not shown). It can be locked at the retracted position β. The push plate 23 communicates with the picking plate 22 via the cam mechanism, and is provided at a position facing the tip of the base frame 18. When the push plate 23 is lightly pushed down by the base frame 18, the picking plate 22 is unlocked, and the picking plate 22 is rotated to the gripping position α by the urging force. When the push plate 23 is further pushed down, the picking plate 22 is rotated forward by the cam mechanism and locked at the retracted position β. In the horticultural binding machine 1 of the present embodiment, the configuration of the tape gripping mechanism 13, the tape magazine 8, the tape guide stand 7 and the like can use the configuration of the conventional horticultural binding machine as it is. Detailed description is omitted.

  The ultrasonic vibration unit 26 is disposed at a position immediately after the tape gripping mechanism 13 of the lifting arm 6. The ultrasonic vibration unit 26 includes a cylindrical portion 27 containing an ultrasonic transducer, and a horn 28 disposed on the upper portion of the cylindrical portion 27 and having a diameter reduced upward. The ultrasonic vibration unit 26 is disposed so that the binding tape 10 can be gripped between the tip of the horn 28 and the anvil 20. The ultrasonic vibrator of the cylindrical portion 27 is connected to the oscillating device 3 via the electric cable 4, and when a high frequency electric signal is input from the oscillating device 3, the cylindrical portion 27 is ultrasonically vibrated. The ultrasonic vibration of the cylindrical portion 27 is amplified by the horn 28 and transmitted to the tip of the horn 28.

  As shown in FIG. 2, a push button type operation switch 29 for operating the oscillation device 3 is provided on one side surface of the base frame 18. The operation switch 29 is connected to the oscillation device 3 via the electric cable 4. The oscillation device 3 transmits an electric signal for a predetermined time to the ultrasonic vibration unit 26 every time the operation switch 29 is pressed once.

  The bundling operation is performed by holding the main handle 5 and the operating lever 9 and moving the tip of the lift arm 6 closer to the tip of the main handle 5. First, from the initial state shown in FIG. 3A, the tip of the lift arm 6 is brought close to the push plate 23 to contact the tip of the base frame 18, and the push plate 23 is lightly pressed down (FIG. 3B). reference). As a result, the picking plate 22 rotates to the gripping position α, the hook-shaped protrusion of the picking plate 22 pierces the tip of the binding tape 10, and the tip of the binding tape 10 is moved by the picking plate 22 and the tape holding plate 24. Locked. In this state, the anvil 20 and the horn 28 are touched lightly, and the anvil holding frame 19 hardly tilts. Then, when the operating lever 9 is loosened from this state and the tip of the lifting arm 6 is separated, the tip of the binding tape 10 is pulled by the picking plate 22 as shown in FIG. As a result, the binding tape 10 is stretched between the main handle 5 and the tip of the elevating arm 6. Then, in such a state, when the bound body P (a crop branch, a support, etc.) is applied to the bound binding tape 10 and pushed into the bound body accommodating portion A between the main handle 5 and the lifting arm 6, As shown in FIG. 4D, the bound body P is surrounded by the binding tape 10 in the bound body housing portion A.

  Then, when the tip of the lifting arm 6 is again approached from the above state, as shown in FIG. 4E, both ends of the binding tape 10 around the binding body P are connected to the tip of the horn 28 and the anvil 20. Sandwiched between. When the operation switch 29 is pressed in such a sandwiched state, the ultrasonic vibration portion 26 vibrates for a predetermined time, and the binding tape 10 sandwiched between the horn 28 and the anvil 20 is welded.

  When the binding lever 10 is held between the horn 28 and the anvil 20 and the operating lever 9 is further gripped, the anvil holding frame 19 tilts upward against the urging force as shown in FIG. Then, the base frame 18 is approached. Thereby, the anvil 20 approaches the tape cutting blade 12, and the binding tape 10 is cut at a position immediately before the clamping part (welding part). At the same time, the push plate 23 is pushed deeply, and the picking plate 22 rotates forward from the gripping position α and is locked at the retracted position β. When the operating lever 9 is loosened from this state and the tip of the lifting arm 6 is separated, the initial state (see FIG. 3A) is obtained, and the bundled body P bound by the binding tape 10 is covered. It becomes possible to extract from the bundled body accommodating portion A.

  As described above, according to the horticultural binding machine 1 of the present embodiment, since the objects to be bound can be bound only by the binding tape without using staples, there is little adverse effect on the soil. Further, since the binding tape is bonded by welding, a sufficient binding force can be obtained. Moreover, it can harmonize with the conventional tape cutting blade and the tape gripping mechanism without any problems.

  The horticultural binding machine in the present invention is not limited to the embodiment described above, and various modifications can be made without departing from the gist of the present invention.

  For example, in the embodiment, the ultrasonic vibration unit 26 is vibrated by the operator manually pressing the operation switch 29, but the configuration of the operation switch can be changed as appropriate. FIG. 5 shows a modification in which the configuration of the operation switch is changed from the above embodiment. The operation switch 29 a of the modification is configured by a contact switch disposed inside the base frame 18. The operation switch 29a is turned off when the anvil holding frame 19 is urged downward as shown in FIG. 5 (a), and the anvil holding frame 19 is tilted upward as shown in FIG. 5 (b). In this state, the contact with the anvil holding frame 19 is turned on. The operation switch 29a is connected to the oscillation device 3 in the same manner as in the above embodiment. When the operation switch 29a is turned on, an electrical signal for a predetermined time is transmitted from the oscillation device 3 to the ultrasonic vibration unit 26. . According to such a modification, when the binding tape 10 is sandwiched between the horn 28 and the anvil 20 and the horn 28 is strongly pressed against the anvil 20 and the anvil holding frame 19 is tilted upward, the operation switch 29a is The binding tape 10 is welded by operating. That is, in such a configuration, the operator can weld the binding tape 10 by simply grasping the operating lever 9 from a state in which the binding tape 10 is sandwiched without directly operating the operation switch.

  In the horticultural binding machine of the present invention, the ultrasonic vibration unit may be disposed on the main handle side, and the anvil may be disposed on the lifting arm side. Further, the oscillation device may be provided integrally with the binding machine body.
