Description

  The present invention uses an adhesive tape as a binding material, in particular, in a binding machine for binding and fixing stalks, branches, vines, etc. of crops together with a splint or a tensile string-like material together with a binding material. The present invention relates to a technique for enabling adjustment of a binding condition without wasting a tape.

  As a binding machine using adhesive tape as a binding material, the lever is operated to hold the free end of the roll-shaped tape between the tape clamps and remove the adhesive surface in front of the receiving part formed in the concave shape of the frame. Pulled out in the state facing the tape, and the object to be bound is brought into contact with the outer surface of the pulled-out tape and received in the receiving part, and the adhesive surfaces of the free end side and the intermediate part of the tape are bonded to each other. Conventionally, there has been a structure in which the objects to be bound are bundled together by cutting between the sides.

  However, in such a conventional binding machine, the adhesive surface of the tape directly touches the outer periphery of the object to be bound, and the adhesive force releases the free end before the tape is bonded. There was a problem that it was not possible to bind well and work efficiency was lowered.

  As a technique for solving this problem, for example, Patent Document 1 proposes a method in which a tape is pulled out in a state having a large slack and then bound and bonded.

The end of one side plate 21a is cut out in a substantially circular shape for loading the roll-shaped tape 10, and the end of the cover 21c covers this cut-out portion.

  On one end side of the frame 21, a circular tape holding portion 22 is formed for rotatably holding a roll-shaped tape 10 whose one surface is adhesive. For example, as shown in FIG. 3, the tape holding portion 22 is attached to the side plate 21 b side, and supports the tape 10 with a rotating body 22 a that can be engaged with the central portion of the tape 10.

  On the other end side of the frame 21, a receiving portion 23 formed in a concave shape for receiving the object to be bound is provided. A plurality of guide rollers 24 are provided between the tape holding part 22 and the receiving part 23 as guide means for guiding the free end 11 of the tape 10 so that it can be pulled out from the one end 23 a of the receiving part 23.

  Here, the tape holding unit 22 and the guide roller 24 as the guide means are pulled out in a state where the adhesive surface 10a of the tape 10 pulled out from the one end 23a of the receiving unit 23 faces the inside of the receiving unit 23, and the tape is not bonded. It is formed so as to be received by the receiving portion 23 in a state where the object to be bound is in contact with the surface 10b. A lock release plate 26 extending downward is formed on one end 23 a side of the receiving portion 23.

  The lever 30 is rotatably attached at one end to a lever shaft 31 inserted into the other end 23b of the receiving portion 23 of the frame 21, and is always urged in an opening direction by an urging means such as a spring (not shown). Yes. A connecting pin 32 projects from the inside of the intermediate portion of the lever 30.

  The arm 40 is rotatably attached at one end side to an arm shaft 41 inserted between the tape holding portion 22 of the frame 21 and the other end 23b of the receiving portion 23, and the intermediate portion closes the receiving portion 23. The end side extends in the vicinity of one end 23 a of the receiving portion 23.

  The arm 40 is provided with a long hole 42 for receiving the connecting pin 32 of the lever 30, and when the lever 30 is gripped, the distal end side of the arm 40 rotates in a direction approaching one end side of the receiving portion 23. When the operation of loosening the grip of the lever 30 is performed, the distal end side of the arm 40 rotates in a direction away from the one end side of the receiving portion 23.

  The tape holding body 50 is provided at the tip of the arm 40, holds the free end 11 of the tape 10 pulled out from the one end 23a of the receiving portion 23, and is linked to the movement of the arm 40 to change its posture.

  For example, as shown in FIG. 2, the tape clamping body 50 is provided on a pair of side plates 51, 51 facing each other and a first clamping body 53, which is erected so as to connect one end side of the side plates 51, 51, and the side plate 51. Both ends of the elongated hole 51a are supported, and the second clamping body 54 slidable in the direction of the first clamping body 53, the tape cutter 55 projecting upward from the outside integrally with the second clamping body 54, the second clamping A spring 56 for urging the body 54 in the direction of the first sandwiching body 53, a projection plate 57 that is attached to the outside of the first sandwiching body 53, projects both ends to the side of the side plate 51, and projects outside the one side plate 51. A lock plate 58 is rotatably supported at one end by a shaft 54a of the second sandwiching body 54.

  The lock plate 58 has a triangular projection 58 a on the other end abutted against the projection plate 57 so that the first clamping body 53 and the second clamping body 54 are separated from each other, and the tip of the lock release plate 26 is moved. When the other end side is pushed downward and the contact between the protrusion 58a and the protrusion plate 57 is released, the first holding body 53 is moved in the direction to contact the second holding body 54 to hold the tape.

  The distal end of the shaft 54a of the second clamping body 54 is rotatably supported by a base 61 of a U-shaped rotation base 60 that constitutes the link mechanism of this embodiment. Hereinafter, the structure of the link mechanism including the rotation base 60 will be described.

  A shaft hole 64 is formed at the tips of the arm portions 62 and 63 extending from both ends of the base portion 61 of the rotation base 60 so as to face each other, and the shaft hole 64 is supported along the inner wall of the arm 40. One end 70a side of the shaft 70 is inserted.

  A shaft slide cam 66 is attached to the shaft 70 at a position between the arm portions 62 and 63 of the rotation base 60. The shaft slide cam 66 abuts against the projection plate 57 and transmits the force to the shaft 70 when the tape holding member 50 rotates about the shaft 54a, and slides the shaft 70 toward the other end 70b.

  Here, on the outer periphery on the one end 70a side of the shaft 70, ribs 71 project at an interval equal to the interval between the arm portions 62 and 63 of the rotation base 60, and the shaft holes 64 of the arm portions 62 and 63 have this A groove 64 a that engages with the rib 71 is formed, and the shaft 70 slides to the other end side, whereby the rib 71 is engaged with the groove 64 a, and the tape holding member 50 is integrated with the shaft 70. It will turn.

  The intermediate portion of the shaft 70 is slidably and rotatably supported along the inner wall of the arm 40 by the support member 75, and the other end 70b extending to the intermediate portion of the arm 40 is formed in a crank shape.

  A shaft rotation cam 80 is attached to the middle portion of the arm 40 to contact the other end 70 b of the shaft 70 slid by the shaft slide cam 66 and rotate the shaft 70.

  The shaft rotation cam 80 is supported by a support member 81 fixed to the inner wall of the arm 40 so as to be rotatable about an axis parallel to the length direction of the arm 40, and when the arm 40 moves in the closing direction, the frame rotates. One end abuts against the projecting portion 27 projecting from 21 and rotates, and the rotational force is transmitted to the shaft 70 from the other end.

  A slide plate 90 is slidably attached to the arm 40 in the length direction of the arm 40. The slide plate 90 extends in the direction of the frame 21 from the other end of the base 91, the base 91 extending in the length direction of the arm 40, the first protrusion 92 extending in the direction of the tape holding body 50 on the distal end side of the base 91. And a second protrusion 93.

  The slide plate 90 is supported so that a pin 45 protruding from the inner wall of the arm 40 is inserted into a long hole 91 a formed in the base 91 and can slide in the length direction. An inclined portion 93 a is formed at the upper rear edge of the second protrusion 93, and the slide plate 90 is urged in a direction in which the inclined portion 93 a comes into contact with the pin 28 protruding from the frame 21. Thus, when the arm 40 is closed, it is pushed by the pin 28 and slides toward the tape holding member 50 side. The tape holding body 50 is rotationally driven by the sliding movement of the slide plate 90.

  Although not shown in FIGS. 1 to 3, a tape holding body 50 holding the free end 11 of the tape 10 is placed at a predetermined position on the inner wall on one end side of the receiving portion 23 of the frame 21 as described later. A first cam 100 for rotating and a second cam 101 for releasing the tape clamping after cutting the tape are provided.

Next, the usage method and operation | movement of this binding tool 20 are demonstrated.
First, as shown in FIG. 3, when the lever 30 is grasped and the arm 40 is driven in the closing direction, the tape holding body 50 and the first holding body 53 and the second holding body 50 as shown in FIG. In a state where there is a gap between the holding body 54 and the holding portion 54, the receiving portion 23 approaches the one end 23 side, and the free end 11 of the tape 10 is received in the gap.

  Then, as shown in FIG. 4B, when the lock release plate 26 provided on the frame 21 side comes into contact with the tip of the lock plate 58 and the arm 40 is closed, the lock is released as shown in FIG. The front end of the plate 58 is pushed down, the contact with the protruding plate 57 is released, the pair of side plates 51 and the first holding body 53 move to the second holding body 54 side, and the free end 11 of the tape 10 is the first end. It is sandwiched between the sandwiching body 53 and the second sandwiching body 54.

  Next, as shown in FIG. 5, when the grip on the lever 30 is loosened, the arm 40 is rotated in the opening direction, and as a result, as shown in FIG. 11 is moved in a direction away from one end side of the receiving portion 23 while sandwiching 11.

  Then, as shown in FIG. 6B, the protruding plate 57 of the tape holding body 50 comes into contact with the inclined portion 100a of the first cam 100 provided at a predetermined position on the inner wall of the receiving portion 23, and the arm 40 opens. Then, as shown in FIG. 6C, the tape holding member 50 is rotated approximately 90 degrees counterclockwise by being pushed by the first cam 100.

  Further, when the grip on the lever 30 is loosened, the arm 40 opens widely as shown in FIG. 7, and the tape 10 with the free end 11 held between the tape holding bodies 50 is long with the adhesive surface 10a facing the receiving portion 23 side. Pulled out.

  And as shown in FIG. 7, the to-be-bound object 1 is made to contact the non-adhesion surface 10b which has faced the outer side of the tape 10, and is received to the receiving part 23 side. The tape drawing length can be arbitrarily adjusted according to the object 1 to be bound by lever operation.

  Here, when the lever 30 is closed, the slide plate 90 is pushed by the pin 28, and as shown in FIG. 8A, the first protrusion 92 moves to the tape holding body 50 side, and further the lever 30 is closed. Then, as shown in FIG. 8B, the first protrusion 92 pushes the side plate 51 of the tape holding body 50 and rotates the tape holding body 50 approximately 90 degrees counterclockwise.

  As the tape holding member 50 rotates, the shaft slide cam 66 is pushed by the projection plate 57 as shown in FIG. 9A, the shaft 70 slides to the other end 70b side, and the rib 71 is rotated. The groove 64a of the 60 shaft holes 64 is engaged.

  For this reason, the other end 70 b of the shaft 70 is in a state in which the shaft 70 can come into contact with the shaft rotation cam 80. When the arm 40 is further closed and the protrusion 27 of the frame 21 contacts the other end of the shaft rotation cam 80, the shaft 70 is rotationally driven as shown in FIG. Rotates 90 degrees around one end of the shaft 70.

  As a result, the free end 11 side of the tape is clamped by the tape clamping body 50 in a state where a twist of 90 degrees is given as shown in FIG.

  From this state, as shown in FIG. 11, the arm 40 is further closed, the tape holding body 50 enters the inside of the one end 23 a of the receiving portion 23, and the portion of the tape 10 that is pulled out intersects the free end 11 side. In this state, the shaft 70 returns and rotates because the tip of the shaft rotation cam 80 gets over the protrusion 27 of the frame 21.

  For this reason, as shown in FIG. 12, the tape clamping body 50 rotates in the direction in which the tip of the tape cutter 55 faces downward, and the free end 11 side of the tape 10 and the bonding surface 10a on the drawer side are bonded to each other. At the same time, the tip end portion of the tape cutter 55 comes into contact with the position on the drawing side from the bonded portion, and is cut.

  When the arm 40 is further closed, as shown in FIG. 13A, the lower inclined portion 101a of the second cam 101 attached to a predetermined position on the inner wall of the receiving portion 23 and the protruding plate 57 of the tape holding member 50 are provided. And the gap between the first clamping body 53 and the second clamping body 54 is widened, and the clamping of the tape is released. Further, as shown in FIG. The plate 57 is engaged and locked in the open state. As a result, for example, as shown in FIG. 14, the object to be bound 1 bound by bonding of the adhesive surfaces 10 a of the tape with the outer periphery in contact with the non-adhesive surface 10 b of the tape is free to the binding machine 20. It becomes a state.

  From this state, by loosening the lever 30 and opening the arm 40, the object to be bound 1 can be taken out from the receiving portion. At this time, the shaft rotating cam 80 is pushed again by the projection 27 of the frame 21 to rotate the shaft 70, and the tape holding body 50 is in a posture opposite to the above state in a state where no tape is held. Since it moves and returns to the initial state of FIG. 3, it can transfer to the next bundling operation | movement.

  Thus, in the binding machine 20 of the embodiment, the tape holding part 22 and the guide means of the frame 21 are pulled out in a state where the adhesive surface 10a of the tape 10 drawn from one end of the receiving part 23 faces the inside of the receiving part 23. The object to be bound 1 is formed so as to be received in contact with the non-adhesive surface 10 b of the tape 10, and further from the state in which the object 1 is received in contact with the non-adhesive surface 10 b of the tape 10. When the arm 30 is closed, a twist is applied to the free end 11 side of the tape 10 so that the intermediate portion of the tape and the adhesive surface are opposed to each other and bonded together.

  For this reason, since the object to be bound 1 is bundled in a state where it is in contact with the non-adhesive surface 10b of the tape 10, there is no deviation of the holding of the tape due to the adhesion between the tape 10 and the object 1 to be bound, and it can be smoothly pulled out and bundled. There is little waste of the tape, and the bundling condition can be adjusted.

  The structure of the said embodiment does not limit this invention, The structure of the flame | frame 21, the lever 30, the arm 40, the tape clamping body 50, and a link mechanism can be variously deformed.
