Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a binding device for binding comparatively long and narrow objects such as agricultural products such as vegetables and industrial materials using tape.

(Prior Art) This type of binding device generally includes a tape reel rotatably held on a substrate, a tape holder installed on the substrate at a predetermined distance from the tape reel, and a tape reel that is attached to the tape reel. It has a binding arm which is disposed between the tape holder and is pivotally attached to the base plate so as to be able to be raised and lowered. The tape holder is provided at a position where the ends of the binding arms meet when the binding arms are laid down, and the tape reel is placed near the base end of the binding arms, and the tape reel is unwound from the tape reel. The tape is stretched along the length of the binding arm,
Furthermore, the end of the tape is pulled out from the tip of the binding arm and held by the tape holder.

In such a device, in order to bind an object, the object is pressed down against the tape extending between the tip of the binding arm and the tape holder, and the base end of the tape holder and the binding arm is pressed down. Place the objects to be bound on the mounting plate installed between the It will be tied up twice.

By the way, as is clear from the foregoing, in the above-mentioned conventional device, since the tape reel is located near the base end of the binding arm, the tape is stretched along the longitudinal direction over the entire length of the binding arm. If the binding arm has a plurality of rolls, the tape is stretched over the rolls, and if the binding arm has a roll only at the tip, the tape is stretched over the roll. Therefore, when the binding arm is tilted, an unwinding force is applied to the tape, so a 1M force direction force is applied to each roll, which causes the binding arm to be tilted. In this case, more force than necessary is required, which becomes a considerable burden when the number of times of tying is large.

Also, when the device is not in use, the adhesive part of the tape (t!
11, it is easy for BL lumps and the like to adhere to the tape, and once they are attached, it loses its adhesiveness, so when using it, the relevant part must be removed and the tape newly drawn from the tape reel. However, conventional equipment Now, as mentioned above, the tape on the binding arm is I7! f. Because it is stretched in the longitudinal direction over its entire length, the part that is pulled out from the tape reel and exposed to the outside air is long, and therefore the part that is removed is long;
As a result, a lot of tape was wasted.

Furthermore, when the binding arm is tilted, an unwinding force is applied to the tape, which causes the tape to elongate, but the elongation rate is
The longer the length of the tape that is pulled out from the tape reel, the larger the length. Therefore, in conventional devices where the length of the tape is large, the length of the tape to be rewound becomes longer, but the rotation of the binding arm is The angle is always constant regardless of the amount of rewinding of the tape, so if the tape cannot be tensioned sufficiently within the range of the rotation angle, the machine must be devised so that it can be tightened within the range of the rotation angle. It was necessary to cover the amount of tape that could not be covered, but this led to the complexity of the mechanism.

(Object of the Invention) In view of the above problems, the present invention aims to shorten the length of the tape drawn out from the tape reel as much as possible.

(Description of the invention) The present invention consists of 1. The binding arm is pivoted to the three III units so that it can be raised and lowered freely,
A binding device for winding the tape pulled from a rotatable tape reel around an object to be bound by the M-folding motion of the binding arm, and binding the winding end to the tape end on the tape holder. In the above, the tape reel mentioned in @ is provided in the vicinity of the tip of the binding arm and independent of the binding arm when standing up (on top of the binding arm), and is connected to the tilting movement of the binding arm and is connected to the tilting movement of the binding arm. By providing a rewinding mechanism that can apply rewinding force to the tape reel at least until the ends of the tape windings are bound during operation, the length of the tape tensioned by c1 binding arm VtC is made as short as possible. In other words, by minimizing the bones of the tape that are exposed to the outside air, the force required to tilt the binding arm is reduced, and by burning the areas where dust etc. adhere as much as possible, tape waste can be eliminated and the tape The aim is to minimize the extension of the

is protruded, and when rotating rod 2■ rotates clockwise,
The other end of the rotating rod 21 is brought into contact with it.

One end of the connecting rod 29 is connected to the pin 3 at one end of the rotating rod 21.
It is rotatably mounted via ( ) 7, and the series J-
The other end of the rod 29 is connected to the link as described above]
The other end of the IJ is rotatably provided via a pin 17.

In the drawings, 30' denotes a brake part of the tape reel 3, which includes a friction plate 31 slidably fitted onto the rotating shaft 19 of the tape reel 3, and a friction plate 31 which is also slidably inserted into the rotating shaft 19 of the tape reel 3. It consists of a pressing plate 32, a nut 33 fitted with a rotation '11111.9, and a coil spring 34 interposed between the pressing plate 32 and the nut 33, which screws the nut 33 in the direction of the tape reel 3. By moving the tape reel 3, the rotation of the tape reel 3 is braked.

In FIG. 1, reference numeral 3-5 is a crimping member which abuts against a tape holder (not shown) when the bundle Fl+i 2 is laid down. The winding end of the tape T wound around the object to be bound is crimped to the tape on the tape holder, and when the binding arm 2 is further tilted from this state, the tape T is cut by a cutting blade (not shown). It will be disconnected by.

Next, the operation of the device having the above configuration will be described.

In the upright state of the binding arm 2 shown in FIG. 1, the claw member 7 and the carrier member 8 are located at the position shown by the solid line, and the tip of the claw member 7 is in contact with the IE shaft 9 from below.
Place the object to be bound (not shown) on the tape T.
When pressing down on the a side button and placing the object to be bound on the R placement plate (not shown), r! After that, when the binding arm 2 is folded down, the claw member 7
As the binding arm 2 is tilted, the carrier member 8 begins to rotate counterclockwise from the position indicated by the solid line, and as the claw member 7 rotates, the carrier member 8 also begins to rotate counterclockwise from the position indicated by the solid line. It turns out. 8 carrier members, spring @' 13
K, the member 8 is resiliently biased counterclockwise, and therefore the member 8 is always pressed against the guide pin 17, and therefore the member 8 rotates while slidingly contacting the guide pin 17. , as the carrier member 8 rotates, the link 10
Also times! ! +axis L5ff: Rotates counterclockwise around the center.

By the way, the engagement between the claw member 7 and the locking shaft 9 is released when the carrier portion 8 is rotated to the extent that the crimping member 35 collides with a tape holder (not shown). Therefore, the carrier member 8
has a widened part 8a that becomes wider toward the other end, that is, the end where it is attached to the link 10, and when the guide bin 17 engages with the inclined part 8b that defines this widened part 8a, the carrier The member 8 rotates clockwise around the mounting shaft 11, and when the crimp member 35 abuts against the tape holder as described above, it engages with the claw member 7, as shown by the dashed line in the figure. The engagement with the stop shaft 9 will be released.

On the other hand, as the link IO rotates, the connecting rod 29 pivotally supported at the other end is lowered, and therefore the six-swivel rod 21 pivotally supported at one end of the connecting rod 29 moves from the position shown by the solid line. The rotation rod 21 will rotate counterclockwise.
When the lever rotates to a certain extent, the pawl 22 engages with the pawl 20, so when the rotating rod 21 rotates further from this position,
Since the ratchet wheel 20 rotates counterclockwise and the tape reel 3 also rotates counterclockwise, a rewinding force is applied to the tape T when the binding arm 2 is tilted.

Then, when the binding arm 2 is laid down and the tape T is completely crimped, the carrier member 8 has reached the position shown by the dashed-dotted line, as described above, and at the same time, the link 10 has also reached the position shown by the dashed-dotted line. As shown in the figure, in this state, the engagement between the carrier member 8 and the claw member 7 is released. And in this way, the carrier member 8 and the claw member 7
When the engagement with the carrier member 8 is released, the restraint of the carrier member 8 is released, and as a result, the carrier member 8 is pulled by the restoring force of the spring 12 and returns to the position shown by the solid line.

Since the link 10 also rotates in the clockwise direction with this return movement of the carrier member 8, the connecting rod 29 rises, and as a result, the rotating rod 21 rotates clockwise, so that the pawl 22 When the proximal end surface of the pawl 22 comes into contact with the pin 27 after detaching from the pawl 20, the pawl 22 rotates in the direction @1 against the biasing force of the spring 25, so that the tip of the pawl 22 further In this way, when the tied arm 2 falls down, the claw 22 separates from the hook 20, so when the tied arm 2 stands up, t.
The tape reel 3 is in a state where it can rotate freely,
Therefore, no unwinding force is applied to the tape T1
, Sennohane: As the east lB 112 stands up, the claw member 7 rotates in the direction t1, and the binding arm 2 returns to the upright position 1.
When approaching the row, the tip of the claw member 7 engages with the locking shaft 9 (7
, when the binding arm 2 further moves in the standing direction, the claw 111 (
The support 7 rotates the carrier member 8 in the 1.'j 'i, i, jj directions, and when the binding arm 2 reaches the upright position, the claw member 7 When the carrier member 8 reaches the position shown by the solid line and comes into contact with the lower side of the locking shaft 9, the carrier member 8 returns to its original position.

FIG. 4 shows a second embodiment of the present invention, in which a claw member 36 has a plurality of long holes 36a at its base end.
The member 36 is fixed to the binding arm 2 by a bolt 37 having a head whose diameter is larger than the width of the elongated hole 36a.

In the support plate 1bK, a lever 38 is rotatably attached via a pin 39, and a connecting rod 29 is rotatably attached to one end of the lever 38. A spring 40 is attached to the lever 38, and the lever 38 is biased counterclockwise about the pin 39 by the spring 40. At the other end of the lever 38,
One end of the link 41 is rotatably attached via a pin 42, and the link 41 is biased clockwise by a spring 43 attached to the lever 38. A roll 44 is rotatably or fixedly attached to the other end of the link 41, and the claw member 36 can be engaged with the roll 44. Furthermore, the above lever 3B
1, a stopper 45 is attached that can freely come into contact when the link 41 moves in the load direction, and also supports the support plate ib.
A stopper 46 is attached to the stopper 46, which can come into contact with the lever 38 when it is turned counterclockwise.

The effect of the position of the button in the same figure will be briefly described.

When the ending arm 2 is erected, the tip of the claw part @36 touches the roll 44.
T 111. lj, the link 41 is still in contact with the stopper 45, and the lever 38 is still in contact with the stopper 46, respectively.

From this state p, if we make the ending J11412 a thin j, we get
Since the claw member 36 rotates 1 degree clockwise, the link 41 also rotates in the direction b1, and accordingly, the lever 38 also rotates in the 1 direction around the bottle 39.
The connecting rod 29 does not move to T11, and as a result, the tape reel 3 receives 1. M force will act on it.

1 The link 41 moves the bin 4 as the claw member 36 rotates.
2, the roll 44 of the link 41 and the claw member 36 are engaged with each other when the crimp portion 35 shown in FIG. 1 abuts against the tape holder. It is set to be removed. The pricing relationship between the link 41 and the claw member 3G immediately after the touch is removed is indicated by a chain line. When the engagement between the claw member 36 and the link 41 is released in this manner, the lever 38 and the link 41 are released from the restriction and become free.

The lever 38 is rotated counterclockwise around the bin 39 by a spring 40, and a link 41
is rotated by the spring 43 about the bottle 42 in the direction of force η↑, and these rotations cause the lever 38 to rotate.
is attached to the stopper 46, and the link 41 is attached to the stopper 45.
At the time of 8, it moves upward to the connecting rod 29 as it rotates in the itt direction,
As a result, the tape reel 3 can rotate freely as in the first embodiment. .

On the other hand, when the claw part u36 turns w1 to the counterclockwise H1 force as the ending arm 2 stands up, it becomes . 9 in the roll 44 of
1 (If the 11th movement is turned, the ring will turn 41 &-, i will turn 1 counterclockwise, and when the 2nd position is 1), the nail gun will turn. Ahead of mouth 315; IA
As shown in Jikken, 佽 goes against and aligns with the capital of 1-ru 44.

In addition, if the above-mentioned bolt 37' is less than loosened, the claw member 36 is
By appropriately setting the position of the claw member 36 that can be rotated l11 freely within the length range of 6i, the timing of engagement of the tip of the claw part ′@36 and the roll 44 can be adjusted. It becomes possible to adjust the timing of the start of one movement of the connecting rod 29, the timing of releasing the lock, and the timing of the tape reel 3 coming into a state where it can freely rotate.

FIG. 5 shows a third embodiment of the present invention, in which the ending arm 2
The claw member 47 provided at the base end has a long hole 48 for the number of rice grains at one end thereof, and has a head having a diameter larger than the width of the long hole 48. A lever 50 is rotatably attached to the support plate 1b via a pin 51, which is fixed to the binding arm 2 by a bolt 49. A connecting rod 29 is attached to one end of the lever 50. is rotatably attached via a bin 52. One end of a link 54 is rotatably attached to the other end of the lever 50 via a pin 53.
A roll 55 is rotatably or fixedly attached to the other end of the claw member 47, and the other end of the claw member 47 can be engaged with the roll 55.

The link 54 and the lever 50 are connected by a spring 56, and the spring 56 biases the link 54 in the tense direction. A stopper 57 is attached to the other end of the lever 50, and when the link 54 rotates clockwise, the link 54 comes into contact with the stopper 57. In addition, there is a guide pin 58
When the hinge 58 is attached, the link 54 moves along the hinge 58.

Next, the operation of the apparatus shown in FIG. 4 will be described.

When the binding arm 2 is upright, the other end of the claw member 47 is in contact with the bottom side of the roll 55, and when the binding arm 2 is tilted from this state, the link 54 is activated by the force of the spring 56. The lever 29 moves upward while sliding on the guide pin 58, and the lever 50 rotates clockwise at the same time, so the connecting rod 29 does not move downward. For this purpose, rewinding force or rl: will be used.

Furthermore, when I tilted my arm 2, I placed it in the guide bin 58.
The swollen portion 54a of the link 54 gradually engages, and as a result, the link 54 is rotated in the opposite direction, so that the roll 55 and the claw member 47 are held together or gradually deweighted. When the binding arm 2 and a tape holder (not shown) come into contact with each other in this direction, the engagement between the two is released.

If the two bindings are moved separately in 1), the link 54 &
Yo spring 56! /11 shot 1.''Force i (therefore, it will not rotate in the direction of time il. During this rotation, the engagement point between the link 54 and the guide bottle 58 is from the bulging portion 54m to the contracting portion 5
Since the link 54 moves 4bK, the link 54 does not move downward.As a result, the lever 50 rotates counterclockwise, so the connecting rod 29 also moves downward.In the same manner as above, the tape reel 3 On the other hand, in response to the rising of the binding arm 2, the claw member 47 is allowed to rotate counterclockwise. The end engages the roll 55.

When the link 54 is rotated counterclockwise and the binding arm 2 reaches the upright state, the other end of the claw member 47 comes into contact with the lower side of the roll 55.

(Effects) As is clear from the above, the present invention provides tape reels with
Since it is located near the tip of the binding arm when standing up,
It is not necessary to stretch the tape over the entire length of the binding arm in the longitudinal direction, and therefore, when the binding arm is tilted, the force acting on the binding arm in one direction of the base is reduced compared to the conventional example. , since the length of the tape that can be wrapped around the roll located at the tip of the binding arm becomes shorter, the frictional resistance becomes smaller, which reduces the amount of effort required to tilt the binding arm. As shown in the figure, it is not necessary to extend the tape over the entire length of the binding arm in the longitudinal direction, and for this reason, the tape is not pulled out from the tape reel by pebbles, or the parts where awns, dirt, etc. may be added. decreases, so
The amount of tape that needs to be removed is reduced, and waste of this waste tape can be eliminated.

Moreover, as shown in the above example, since the amount of tape pulled out is small, the elongation rate of the tape extended by one length due to the unwinding force is as small as a pebble, and therefore the length of the tape to be unwound is shortened, even if the binding arm is Even if it is not possible to tension the tape sufficiently within the range of rotation angle #lq, the length of the tape to account for the loosening is shorter than before, and the length of the tape that cannot be tightened within the range of rotation angles above. The rewinding mechanism for covering this will be much simpler than the conventional example.
