Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a device for tying vegetables, etc., and in particular, to a device for tying vegetables, etc., that can prevent damage to the objects to be tied, such as vegetables, during tying and provide a stable tying state. In order to achieve this, wide tape is used as a binding material,
Moreover, this tape relates to a device in which knots are tied using the tape itself without using any special binding fittings or the like.

[Conventional technology]

Hitherto, binding devices of the type of the invention are unknown.

[Technical problem of the present invention]

The tying machine according to the present invention is characterized by being able to obtain a stable string binding state using a wide tape for soft objects such as vegetables, and also by tying the ends of the tape itself. This makes it possible to obtain a highly reliable binding state using only this tape.

[Technical means of the present invention]

The present invention provides a tape reel for storing a wide tape for binding, an operation handle for operation, a tape wrapping means for guiding the tape around objects to be bound in a wide shape, and a tape winding means for guiding the tape around objects to be bound in a wide shape. tape holding means for holding the leading and proximal ends of the wrapped tape; tape gathering means for gathering the wide tape at the binding section; binding means for binding the gathered tape portions; and cutting off the remaining portion of the bundled tape. and a cutting means, and the binding means bends the tape into a loop shape with a beak that can be rotated and freely opened and closed, and when the loop-shaped portion is removed from the beak, one end of the tape is inserted into the loop. In a vegetable tying machine capable of tying vegetables, a groove is formed in the upper part of the beak of the tying means, and a latching part is provided at the tip of the knot removal plate to hook the loop-shaped part in the groove. However, the knot can be tightened by pulling the loop-shaped part with this hook part and pulling the end of the tape with the beak.

[Operation of the present invention]

By the above means, the present invention has a mechanism at the upper part of the beak, and the knot is caught in this groove to take it out.
There is a part in front of it for tightening the knot. Therefore, since the knot is directly hooked and removed, the knot does not become loose.

Similarly, the parallel pin 80 that is engaged with the cutter plate 70 is also connected to each of the first and second links 7.
The rotational force from the handle shaft 24 is transmitted as the operating force of the cutter plate 71 through a transmission mechanism having the same structure as the rotary plate unit 56 and the rotary plate unit 56.

In the above configuration, the method of operating the push-in plate 5 will be described. When the handle shaft 24 is rotated clockwise around the middle stepped pin 26 in FIG. 26 is rotated, and the Geneva unit 18 is similarly rotated clockwise in FIG. 1 about the parallel pin 16A via the gear 22 from the gear 23 integrally supported by the pin 26. Then, the roller 182 engages the engaging portion 18 of the Geneva 19.
4, so Geneva 19 and sector gear 1
5 is a gear 1 that is rotated counterclockwise around a parallel pin 16B and meshes with the sector-shaped gear 15.
The arm 4, which is attached to a stepped pin 3 integral with the stepped pin 3, is rotated clockwise around this pin 3, and therefore the push plate 5 is rotated clockwise around the stepped pin 3. It is rotated. In the state shown in FIG. 1, the handle shaft 24 is in an unoperated position, and at this time, the roller 182 of the Geneva unit and the engaging portion 184 of the Geneva 19 have begun to engage. At this time, one recess 192 of Geneva 19 is
81. Then, by operating the handle shaft 24 from this state, the roller 182 is moved clockwise around the parallel pin 16, and even after the roller 182 is disengaged from the engaging portion 184 of the Geneva 19, the handle shaft 24 When rotated, the Geneva 19 reaches the end of movement in the counterclockwise direction around the parallel pin 16B, that is, the other recess 193 of the Geneva 19 engages with the disk portion 181, and thereby the Geneva The sector gear integral with 19 remains stopped. However, the handle shaft 24 is further moved clockwise around the stepped pin 26 to carry out the stringing process, binding process, and cutting process, which will be described later.

In this way, the pushing plate 5 for pushing the tape is intermittently driven by the Geneva unit 18 and Geneva 19, and the pushing plate 5 for pushing the tape is driven until the end of binding.
remains in its end-of-operation position, i.e., in the position in which the tape is pushed in. In this way, the push plate 5 is temporarily stopped at the push-in position until the handle shaft 24 is operated to return, and during this pause, the bundling,
Since operations such as cutting are performed, the pusher plate 5 does not return during bundling or the like.

Next, the operating mechanism of the beak 36 and beak unit 37 will be explained.

That is, to operate this beak 36,
A stepped pin 2 rotated by the handle shaft 24
The rotational force of 6 is received by the miter gear 31 integrated with the parallel pin 32 through several stages of gears (not shown), and the Geneva unit 31 is further integrated with the parallel pin 32.
Rotate 1. Note that, as shown in FIG. 5, this unit 311 has a Geneva 3 attached to the outer periphery of the notched disk portion 313 of the Geneva unit 311 when not in operation.
12 is in an engaged state, and the roller 318 is at the farthest position from the Geneva 312. At this time, Geneva 31
One end 319A of the fan-shaped gear 319 integrated with the beak shaft 314 meshes with the gear 315 integrated with the beak shaft 314.
At this time, the beak 36 is in the state shown in FIGS. 1, 3, and 4. Therefore, as the rotation operation of the handle shaft 24 progresses, the Geneva unit 311 rotates around the parallel pin 32, and when the roller 315 eventually fits into the notch joint 320 of the Geneva unit 312, as the Geneva unit 311 rotates, Geneva 312
is rotated counterclockwise in FIG. 5 around the parallel pin 33, and the fan-shaped gear 319 is
The beak shaft 314 is rotated. The rotation of the beak shaft 314 is performed while the roller 315 is engaged with the engaging portion 320 of the Geneva unit 312 in FIG.
When the gear 314 is disengaged from the engaging portion 320, the other concave portion 317 of the Geneva 312 is engaged with the peripheral portion of the notched disk portion 313, and the rotation of the gear 314 is temporarily stopped. At this time, the fan-shaped gear 319 is meshed with the gear 314 near the other end 319B of the gear. Then, when the handle shaft 24 is returned, the Geneva unit 311 is reversed, and the roller 315 is moved again to the engagement portion 320 of the Geneva 312.
5 to return Geneva 312 to the state shown in FIG. Therefore, at the time of this reversal, the beak 36 is also reversed.

Note that the beak 36 and beak unit 37 function to tie the binding tape.
The binding tape is bound without using a special binding fitting or the like during forward and reverse rotation in conjunction with the operation of the handle shaft 24, and its detailed operation will be described below.

Next, the operation of applying the binding tape T around the object to be bound will be explained.

In this device, a wide tape T used for bundling is fed out from the outer periphery of a bundle that has been previously stored on a tape reel (not shown), and the tip of the tape T is pushed along the outer surface 5A of the plate 5, and then the tip 5B is pushed out. It is placed so that it is hung around the jaw pin 66 and the tip edge _T1 is held by the tape gripping mechanism. As a result, the tape T is stretched vertically between the tip 5B of the pushing plate 5 and the jaw pin 66 (first
(see figure). Therefore, from this state, the object to be bound
is set on the table 81 from the direction of arrow A with respect to the tension tape T, and the handle shaft 24
When the pushing plate 5 is actuated by pulling , the plate 5 moves around the object to be bound O, and its tip 52 is inserted under the jaw pin 66. Then, the tape T
As shown in FIG. 6A, when the pushing plate 5 is further moved, the lifting plate roller 10 of the plate 5 is moved around the lifting operation plate
The upper edges 11a and 12a of 1 and 12 are abutted and connected to each other. Then, the lifting plate 6 uses the parallel pin 9 as a fulcrum, and the tip 6b side moves upward in the figure as shown in FIG. 6B, and the pushing plate 5 is further moved to its final end of movement as shown in FIG. 6C. Then, since the parallel pin 9 serving as the fulcrum is located below the upper edges 11a and 12a, the tip 6b of the lifting plate 6 moves further upward, and the tape T is brought close to the tip of the table 81. become. Therefore, tape T
As shown in FIG. 6C, both ends of the jaw pin 66 and the tip 6b of the lifting plate 6, which are wrapped around the object O, overlap and are connected vertically to the right side of the beak 36 in the figure. It will be installed so that That is, by this, beak 3
6 is hooked onto the tape T with sufficient certainty for binding.

Also, a mechanism for grasping the tip of the binding tape T will be explained. This gripping mechanism holds the leading end of the wide tape T prior to binding, or after wrapping the tape T around the object O, holds both ends of the wrapped tape.

That is, to explain this with reference to FIGS. 1 and 7, in the state before the tape is hung, as shown in FIGS. 1 and 7A, the grip bearing 49 is rotated by the parallel pin 50. A parallel pin 5 is attached to the free end side of the check plate bearing 54 which is freely pivoted.
A check plate 53 is rotatably supported by the check plate bearing 54, and a parallel pin 50 is mounted on the check plate bearing 54.
The base end of the grip plate 51 is rotatably supported by the grip plate 51. Then, the grip bearing 49 and the check plate bearing 5
A torsion coil spring 94 is interposed between the grip plate 51 and the grip bearing 50 to bias the check plate bearing 54 in the counterclockwise direction in FIG. mediated,
The gripping plate 51 is biased clockwise around the parallel pin 50 in FIG. The surroundings are energized clockwise in Figure 7A. At this time, the engaging portion 53a of the check plate 53 comes into contact with the locking protrusion 54a near the tip of the check plate bearing 54, and furthermore, the base end 54b of the check plate bearing 54 comes into contact with the grip bearing 49. It abuts and engages with the protruding piece 49a. In this state, the check plate 53 is not in contact with the bent piece 491 bent from the upper edge of the grip bearing 49, and the grip plate 51 is not in contact with the bent piece 491 bent from the upper edge of the grip bearing 49.
The abutment piece 512 on which the tape T is attached presses against the bent piece 491 from below, and clamps the vicinity of the tip of the tape T.

Therefore, from this state, the handle shaft 24 is pulled and the push plate 5 guides the tape around the object to be bound O, and the push plate 5 closes the bent piece 49 from the tip 5b side.
1 and the check plate 53 as shown in FIG. The plate 53 is moved around the parallel pin 52 in the counterclockwise direction in FIG. 7B. From this state, when the tip 5b of the pushing plate 5 is further inserted,
This tip 5b eventually abuts one side of the grip plate 51, and the grip plate 51 is pushed and rotated counterclockwise in FIG. 7C around the parallel pin 50 against the elastic force of the spring 92.

Then, the contact piece 512 of this grip plate 51 is pressed in advance.
The tip of the tape T, which was held between the bent piece 491 and the inner surface 52 of the pushing plate 5, is held between the bent piece 491 and the inner surface 52 of the pushing plate 5, and the pushing plate 5 eventually overcomes the gripping plate 51, as shown in FIG. 7D. It is inserted to the deepest part.

In the state shown in FIG. 7D, the tip of the tape T is held between the bent piece 491 and the inner side 52 of the pushing plate 5, and the proximal end of the tape that has been wrapped around the object O The part is from the inner side 5C of this pushing plate 5 to the outer side 5A through the tip 5b.
, and is held between the outer side 51 and the abutting piece 532 to which the rubber 531 of the check plate 53 is attached. Furthermore, this figure 7D
In the state shown in , the tape cutting mechanism operates at the positions indicated by arrows C and P to cut the tape T.
In addition, in the state shown in FIG. 7D, the object to be bound O
Both ends of the tape T wrapped around it are bound.

Therefore, when the handle shaft 24 is returned after binding and cutting the tape T, the push plate 5 is moved to the bent piece 491 as shown in FIG. 7E.
Regress the lower side to the right in the figure. Then, the grip plate 51 that had been pushed down in the state shown in FIG.
12 holds the tape T between the bent piece 491,
As shown in FIG. 7F, the pushing plate 5 is further removed from between the check plate 53 and the bent piece 491, and returned to the initial state shown in FIG. 7A.

It should be noted that FIG. 8 shows an embodiment of another tape gripping mechanism different from that explained in FIG. 7 above, and the one shown in FIG. 8 will be explained here.

That is, in the example shown in FIG. 8, the tip of the tape T has a concave groove 552 carved in the upper end of a fixed grip block 551, and this structure 552
A grip plate 553 is disposed relative to the grip plate 553 so that the tip 553a can be attached and detached. The gripping plate 553 is rotatably supported by a fulcrum pin 554, and as the pushing plate 5 moves, the fulcrum pin 554 moves as shown in FIGS.
It can freely move up and down between the state position shown in FIG.

That is, the tip of the binding tape T is
As shown in FIG. A, the grip block 551 is held in a concave groove 552 between it and a grip plate 553 fitted in the groove 552. At this time, the recessed groove 552 is formed slightly wider, the grip plate 553 is formed into a thin plate shape that is thinner than the width of this groove 552, and the fulcrum pin 554 is arranged at a position similar to that of the recessed groove 552. If the tape T is shifted slightly to the side, the tape T is firmly held at the two contact points 555a and 555b between the grip plate 553 and the groove, and is supported in a stable state. Also,
In this example, a tape T
A shift prevention plate 556 is rotatably supported by a pivot pin 557 so as to set an appropriate running position. Further, a torsion coil spring 558 is interposed between the prevention plate 556 and a bearing 559.
In FIG. 8, the prevention plate 556 is biased clockwise around the pivot pin 557 and is engaged with a stopper protrusion 560 protruding from the bearing 559. Further, numeral 561 in FIG. 8 is a tape running guide shaft, and the tape T is run under the shaft 561 and stretched. Therefore, as shown in FIG. 8A, the tip of the tape T is grasped in advance and the
When the handle shaft 24 is pulled from the tensioned state where it is held between the tape T 51 and the grip plate 553, the pushing plate 5 hooks the middle part of the tape T to its tip 5b, and the object to be bound is pulled. It runs around O and wraps the tape T around it. Then, as shown in FIG. 8B, when the pushing plate 5 reaches the tape gripping mechanism of this example, the tip 5b of the pushing plate 5 hits the deviation prevention plate 556, and the plate 556 becomes its fulcrum. The pin 557 is rotated counterclockwise in the figure against the force of the spring 558. and,
When the pushing plate 5 is further moved, the gripping plate 553 is moved as shown in FIG.
As shown in FIG. 3, the tape is separated from the gripping block 551 and the tip of the tape T that was previously supported is released. In addition, during this process, both ends of the tape T wrapped around the object to be bound O are bound by the binding mechanism, and a cutter acts on a portion of the tape T along the inner side 52 of the pushing plate 5 to cut it. Cut the tape at positions C and P. Furthermore, at this time,
The tip of the shift prevention plate 556 is pressed against the outer side 51 of the push-in plate 5 by the elastic force of a spring 558, and the tape T is therefore held between the press-contact portion 561. Note that the pushing plate tip 5b of the tape T cut in the state shown in FIG. 8C above
The tape portion _T2 from to the cutting position P/C is the 8th
As shown in Figure D, the above-mentioned tape portion is

51 and the grip plate 553 so that it protrudes between them. The state in which the reversing plate 562 has returned is the state shown in FIG. 8E. and,
When the pushing plate 5 starts to return from this state, the gripping plate 553 grips the gripping block 55.
1, the tape T is held between the concave groove 552 of the block 551 and the grip plate tip 553a as shown in FIG. 8F, and the tape T is in the state shown in FIG. Achieve a state where this is maintained.

In addition, FIG. 9 shows a tape reversing brush 56 instead of the reversing plate 562 explained with reference to FIG. 8D above.
This is an example in which 3 is used. Furthermore, in this example, instead of the grip plate 553, a wedge 564 is used.
is used. That is, in the case shown in FIG. 9, a rotary brush 563 whose bristles are radially implanted in the outer diameter direction of a rotary shaft 565 is rotated clockwise along the inner side 5C of the pusher plate 5. This allows the brush 563 to easily grip the tape portion _T2 shown in FIG.
51 and the wedge 564 so as to protrude between them. Then, when the wedge 564 is grasped and fitted into the groove 552 of the block 551, the outer peripheral inclined surface of the wedge 564 is aligned with the groove 552 of the block 551.
2, the tape T
can be supported on two points. In addition, in Figure 9,
The same numbers as those in the above figures indicate the same members.

Next, in this device, when binding both ends of the wide tape T wrapped around the object to be bound O, prior to this binding, the tape portion that will become the binding part is brought together so as to obtain a secure binding state. The tape shifting mechanism will be explained.

In other words, this tape gathering mechanism
In contrast, the tape T, which has been wrapped around in a wide state, is converged so as to be focused toward the beak 36 and beak unit 37 that constitute the tape binding mechanism.

That is, when the tape T is hung around, the tip 67a of the string gathering plate 67 is separated from the proximal end 66A of the jaw pin 66, that is, from the beak 36, as shown in FIGS. 4, 5, and 10A. It is installed in the direction of abdication. After the tape T is wrapped around the object O from this state, the string gathering plate 67 is slid and projected toward the beak 36 by operating the handle shaft 24. Then, the tape compatible recess 671A cut out at the tip of the string gathering plate 67 is located at the overlapping portion T ₃ of the tape stretched vertically from the chin pin 66.
From the side, the tape T is grasped in the recess 671A and gathered toward the beak 36. The string gathering plate 67 is also an auxiliary string gathering plate as _shown in FIG. 6
The tip notch recess 671B of 70 is the tape part
It faces T ₄ from the side. Therefore, the tape T is gathered to the lower side of the beak 36 by the string gathering plates 67, 670 at both sides of the beak 36, as shown in FIG. 10B. At this time, the portion of the tape T wrapped around the object O remains wide.

In this way, when the tape T is gathered to the beak 36 and beak unit 37 sides,
The binding mechanism is then actuated to bind the tape ends.

Next, the operation of the binding mechanism for binding the tapes T gathered together by the above-mentioned string gathering mechanism will be explained (see FIG. 11).

That is, this binding mechanism adopts a method of binding the tapes themselves and does not use other binding members such as binding fittings.

That is, in the binding mechanism, when the beak shaft 314 is rotated by operating the handle shaft 24, the beak 36 is rotated clockwise in FIG. At this time, as shown in FIG. 10B, since the tape T is focused on one side of the rotating side of the beak 36 and is positioned vertically, it is wrapped around the beak 36 as the beak 36 rotates. It catches on like it sticks.

Note that as the beak 36 rotates, the 12th
As shown in the figure, the beak roller 39 of the beak unit 37, which is integrated with the beak 36, rolls along the cam 42 to open and close the lower beak 38 during the above rotation. This operating state is the 12th
To explain with a diagram, when the beak 36 is in a state before starting, the roller 39 is located in a state of being fitted into the recessed part 421 provided on the outer periphery of the cam as shown in FIG. As shown in Figure 3, it is in a closed state, touching the upper beak 36. Also, at this time, cam 4
2, the outer peripheral engagement step portion 422 is the cam check plate 48
10, and is prevented from rotating clockwise in FIG. 10.

From this state, the beak axis 314
As the beak unit rotates, the roller 39 of the beak unit is moved clockwise in FIG.
It is brought into rolling contact with the cam outer periphery 423 from inside 1. Then,
As the roller 39 moves in the radial direction of the cam, the beak unit 37 is rotated clockwise in FIG. activated. Thus, while the roller 39 is rolling along the outer peripheral surface 423 of the cam 42, the beaks 36 and 38 are in an open state. Then, these beaks rotate once around the cam 42, and as shown in FIG.
When the roller 39 falls into the cam 21, the space between the beaks 36 and 38 is closed by the movement of the roller 39 in the radially inner direction of the cam.

Further, the beak shaft 314 is connected to the handle shaft 24.
When the roller 39 is rotated counterclockwise in FIG. 10 with the return of the roller 39, the roller 39 is engaged in the recess 421 of the cam 42 as shown in FIG. 12D. The rotational force in the counterclockwise direction is transmitted, and the beak 36 is moved counterclockwise together with the beak 36. Eventually, it rotates once, and the engaging stepped portion 422 on the outer periphery of the cam is again moved against the cam check plate 48, as shown in FIG. 10E. It is reversed until it engages the tip. In addition, when rotating from D to E in FIG. 10, a relative force is applied to the stepped portion 422 and the cam check plate 48 in the direction of detachment, and the cam 42 and the beak 36 can be easily reversed. .

Note that a beak pressing plate 44 is disposed in relation to the roller 39 so as to press the roller 39 in the radially inner direction of the cam.
As shown in FIG. 3, when the roller 39 is fitted into the recess 421 of the cam 42, the movement of the plate 44 in the radial direction of the cam is prevented by the position regulating bolt 10.
4, a slight gap 441 is maintained between the roller 39 and the roller 39.
The lower beak 38 is designed to have a loose play with the upper beak 36 within the range of the gap 441, thereby making it possible to avoid deterioration in durability due to strong contact between the beaks 36 and 38. There is.

In this way, the beak 36 and the beak unit 37 rotate in the normal direction to bind the tape T. The binding state will now be explained with reference to FIG. 11 again.

First, as shown in FIG. 11A, the beaks 36 and 38, which are still closed, are focused and hooked from the side with the vertically positioned tape T.
8, it wraps around these beaks as shown in FIG. 11B to FIG. 11C. And the first
When the rotation of the beaks 36 and 38 progresses to the state shown in FIG. 1C, the lower beak 38 gradually opens as described above, and a horizontal convergence occurs between the opened beaks 36 and 38 as shown in FIG. 11D. As the tape portion is bitten, when the beaks 36 and 38 rotate once, the beaks 36 and 38 close and bite a part of the tape as shown in FIG. It is wrapped around it in a ring shape.

When the state has reached the above state, the knot removal mechanism operates to complete the knot formation, and as shown in FIG. It consists of the above-mentioned knot removal plate 61, and an L-shaped knot removal pin 611 that fits into the above-mentioned concave strip 361 is protruded from the lower side near the tip of the plate 61.

Therefore, from the state shown in FIG. 14, after the beaks 36 and 38 complete biting and winding the tape, the tying and take-out ring 60 rotates clockwise around the parallel pin 62 in conjunction with the operating handle 24. When it is done, the above-mentioned knot removal plate 6
1 is moved along the upper side of the beak 36, and at this time, the knot removal pin 611 moves within the groove 361, hooks the tape portions wrapped around the beaks 36 and 38, and removes the tape from these beaks as shown in FIG. 14C. Let go like this. At this time, the tape part between each beak 36 and 38 is
When the detached tape is inserted into the ring portion _T5 and the take-out plate 61 is further moved to the right in FIG.
The part T ₆ bitten by the pin 611 and the ring part T ₅ hooked on the pin 611 are pulled together, forming a tight knot. This state is also clear from FIG. 11F. Then, when the ring portion T ₅ is further pulled, each beak 36
As mentioned above, there is a gap between beak 3 and 38, so the tape T is completely attached to beak 3.
6, 38 to complete the binding. Note that prior to or following this bundling, the tape T that continues from the knot to the tape reel (not shown) is cut by a cutting mechanism,
The binding of the objects O to be bound using the wide tape is completed.

Next, a cutting mechanism for cutting the tape T will be explained.

This cutting mechanism uses a wide tape T to bind the tapes, and is designed to cut such a wide tape T easily and accurately.

That is, the inner side 5 of the pushing plate 5 of the tape
The cutting edge 731 of a cutter 73 attached to the cutter plate 70 by a support shaft 73 is slid from the side to slide into contact with the tape T stretched along the direction C to cut the tape. As shown in FIG. 15A, an inclined surface 521 is formed on one inner edge of the pushing plate 5 on the side near the cutter 73, and this inclined surface 521 extends at least to the lower surface of one side edge of the tape T. put. Further, a cutting edge portion 731 of the cutter 73 is biased counterclockwise around a support shaft 73a in the figure by a spring 732. Therefore, this cutter 73 is attached to the tape T.
When the blade edge 731 is brought close to the inclined surface 5,
21, the blade easily enters between the tape T and the inner side 5C of the pushing plate 5 along this inclined surface 521, and the blade pushes the tape T from the side in the pulling direction of the tape T.
It is designed so that it can be easily cut by touching it.

In addition, in the example shown in FIG. 15B, the cutter 73
A cutter guide groove 522 that extends laterally on the inner side 52 of the pusher plate 5 corresponds to the slide position of
has been established. In this example, the cutting edge portion 731 of the cutter 73 is always fitted into the groove 522, and can be reliably inserted between the tape T and the pusher plate 5, thereby achieving even more reliable tape cutting.

Furthermore, the one in Figure 15C is cutter 73,7
3' are used in a two-layered manner, and the inclined cutting edge portions 731, 7
This is an example in which the tapes 31' are arranged in a cross-linked manner to prevent the tape T from escaping during cutting, thereby ensuring a reliable cutting condition.

〔Effect of the invention〕

In the above configuration, since a wide tape is used as the binding material and is wrapped around the objects in a wide shape for binding, a stable binding state can be obtained without damaging the objects.

In addition, since the initial movement of the operation handle and the movement of the tape push-in plate are synchronized, the operator's face is unlikely to hit the tape push-in plate, and furthermore, the tape push-in plate does not hold the tape until the handle is returned. Safety is increased because it remains stopped at the pushed-in position.

In addition, a transmission mechanism using Geneva gears is interposed between the operating handle and each operating mechanism, so
Compared to the system where gears collide, the start of rotation is smoother and durability can be improved.

In addition, in the binding mechanism part, the knot can be easily removed, the mechanism is simple and the crop is secure, the accuracy of the parts can be rough, and manufacturing is easy.

Moreover, since the knot is removed by directly hooking it and pulling it, the knot does not loosen and is tightly tightened.

Furthermore, when the beak of the binding mechanism closes,
Durability is improved because no impact force is applied to the beak or fulcrum pin, and since the closed position of the beak can be adjusted, the load when pulling out the knot from the beak can be reduced.

Furthermore, when cutting the tape, the wide tape is cut in its wide shape, so by grasping the cut end of the tape in its wide shape when grabbing the tape, the tape is stretched flat in preparation for the next bundling. The binding state can always be wide except for the knot.

Furthermore, by placing the wide tape under the chin of the beak, it is possible to tie wide tapes that could not be tied conventionally.

Furthermore, since the tape pushing plate is configured such that the pushing plate is activated after the tape pushing plate advances to the bottom of the object to be bound, it is possible to bind objects with a correspondingly larger diameter. can.

Further, the beak cam is formed independently from the main body, and only this cam is rotatable in one direction, so that the cam is easy to process and easy to replace when damaged.

Furthermore, the tape has the advantage that no chips or the like are generated even if it is cut during bundling.
