Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an improvement in a binding device, and more particularly to a device for binding objects to be bound, such as flower bouquets and vegetable bundles, which are easily damaged during binding with tape.

(Prior art) Conventionally, this type of binding device is shown in Fig.
152400), a mounting table 1' on which objects to be bound A are placed, a tape holding means 2' adjacent to the placing table 1', and a tape holding means 2' that is spaced apart from and close to the tape holding means 2' and a winding device. A tape guiding means 5' for guiding the binding tape 4' pulled out from the tape 3' is provided, and the cut end of the binding tape 4' is held by the tape holding means 2' via the tape guiding means 5'. A binding tape 4' is stretched between the tape holding means 2' and the tape guiding means 5', and the binding tape 4' stretched between the tape holding means 2' and the tape guiding means 5' is covered. By applying and placing the bundled object A on the mounting table 1' and bringing the tape guide means 5' and tape holding means 2' into close contact with each other, the object to be bound A is wrapped with the binding tape 4' and bound. (See Figure 6).

(Problem to be Solved by the Invention) However, in the binding device shown in FIG. 6, the objects A placed on the mounting table 1' are
Since the binding tape 4' is tightened by the unwinding device for the winding tape 3' during binding, it tends to be pulled toward the tape holding means 2'.

Therefore, when binding objects A that have a relatively large internal space, such as a bouquet of flowers or a bunch of vegetables, the objects A are pressed between the mounting table 1' and the tape holding means 2', and Because the shape of the bundle of objects A is also deformed, simply placing the objects A on the binding tape 4' and placing them on the mounting table 1' will not compress the objects A sufficiently. Therefore, there was a problem in that the objects to be bound A could not be bound with sufficient tightening force.

In order to solve such problems, the present invention provides a binding object holding means below the binding object placement part that can lock the binding object clamping body at any rotational position. To bind objects of various sizes, especially objects with relatively large internal spaces such as flower bouquets and vegetable bundles, after tightening them with appropriate compression force in a sufficiently compressed state, and then tying them with tape. With the goal.

(Means for Solving the Problems) In order to achieve the above object, the present invention provides a mounting table on which objects to be bound are placed, a tape holding means adjacent to the mounting table, and a spaced approach to the tape holding means. A tape guiding means is provided, and the object to be bound placed on the mounting table is passed through the tape guiding means and placed on the mounting table against the binding tape held by the tape holding means. In the binding device which wraps and binds the binding tape by closely abutting the binding tape, a binding object guide section is provided upright at one end of the mounting table adjacent to the tape holding means, Furthermore, the object clamping body that can move toward and away from the object guide section on the mounting table can be replaced with a support shaft rotatably provided on the lower side plate of the mounting table. A bound object holding means is provided between the support shaft and the tape holding means, and is capable of locking the bound object clamping body at any rotational position with respect to the bound object guide section. It is characterized by

(Function) With this configuration, when binding objects, the objects to be bound A are placed between the guide section on the mounting section and the clamping body with the end of the tape being held between the clamping bodies. When the clamping body is brought close to the rear side of the crimping table by rotating the handle forward and the object to be bound A is compressed from the left and right between the clamping body and the guide part, tightening is performed. The body can be locked in any rotational position by means for holding objects to be bound provided between a support shaft provided below the mounting table and the tape holding means.

Therefore, objects to be bound of various sizes can be appropriately tightened, so that even if the objects to be bound have a relatively large internal gap, they will not be compressed with an appropriate compression force and will not be damaged.

The invention will be explained in detail below with reference to the illustrated embodiments.

In FIG. 1, reference numeral 1 denotes a base, on which a tape crimping table 2 is protruded near the front end thereof, and behind the tape crimping table 2, a binding object mounting section 3 is provided in a substantially horizontal state.

The second tape holder 13 is provided so as to be able to come into contact with and separate from the rear surface of the first tape holder 9, and is urged toward the first tape holder 9 by a spring 14.

As shown in FIG. 5, a tape pressing body 15 is attached to the arm end 4A of the binding arm 4 via a spring 16 so as to be movable forward and backward. This tape pressing body 1
Reference numeral 5 serves to adhere the adhesive surfaces of the tape 6 together in cooperation with the tape crimping table 2, and this tape pressing body 15 is formed here so as to be able to abut against the upper surface of the tape crimping table 2. However, it may be formed so as to descend along the front or rear surface of the tape crimping table 2.

A clamping control section 17 is provided on the arm end 4A near the tape pressing body 15 for separating the second tape clamping body 13 and the first tape clamping body 9 from each other. Here, this clamping control section 17 consists of an inclined cam section 17A and a vertical cam section 17B.
Both cam portions 17A and 17B act on the two tape clamping bodies 13 in sequence and serve to separate the second tape clamping body 13 from the first tape clamping body 9.

At the arm end 4A of the binding arm 4, when the first and second tape holding bodies 9 and 13 are separated from each other, the first and second tape holding bodies 9 and 13
A cutting blade 18 for cutting the tape 6 is fixed between the second tape holding bodies 9 and 13, and a tape release rod 19 for pushing the tape 6 downward is fixed between the cutting blade 18 and the tape pressing body 15. It is set up. Note that when the tape pressing body 15 is formed to descend along the front and rear surfaces of the tape crimping table 2, the tape release rod 19 may be omitted.

A third tape clamping body 20 is provided at the arm end 4A of the binding arm 4 to clamp the tape 6 in cooperation with the first tape clamping body 9. Here, the third tape holder 20 is attached via a shaft 21 to an intermediate portion of a support rod 22, and the support rod 22 is attached via a spring 23 to the arm end portion 4A so as to be movable back and forth. The third tape holding rod 20 is rotated clockwise in FIG. 1 by the spring 2.
It is energized at 4. The tip of the support rod 23 has a first
Although an auxiliary clamp holder 25 that can collide with the tape clamp rod 9 is attached, this auxiliary clamp holder 25 may be omitted.

A bound article guide section 26 is provided in the vicinity of the rear surface of the tape crimping table 2 . This guide part 26
serves to guide the front side portions of the objects A to be bound into a bundle, and to prevent the objects A from protruding toward the tape crimping table 2 side. This guide part 2
6 is detachably attached to the mounting section 3, and the upper end of the guide section 26 extends above the tape crimping table 2, and at the center of the upper end, there is a guide section 26 shown in FIGS. As shown in the figure, an opening 26A is formed with a width that allows the tape 6 to pass through. This guide portion 26 can be replaced with one of appropriate size and shape depending on the size, type, etc. of the objects A to be bound.

At the rear of the guide section 26, a bound object clamping body 27 that can approach and move away from the guide section 26 is provided, and below the placement section 3, a bound object holding means is provided. This object holding means includes a support shaft 29 rotatably provided on the lower side plate 28 of the placement section 3, a ratchet wheel 31, a spring 32, a stopper member 33, and a spring 34. This serves to lock the tightening body 27 in any rotational position.

The clamping body 27 is replaceably attached to a support shaft 29 rotatably provided on a lower side plate 28 of the mounting section 3 . A handle 30 and a ratchet wheel 31 are fixed to the support shaft 29, and the handle 30 and the side plate 28
A spring 32 that biases the clamping body 27, the handle 30, the ratchet wheel 31, etc. in the clockwise direction in FIG.
is installed.

A stopper member 33 is rotatably attached to the side plate portion 1A of the base 1 via a shaft 34. One end of the stopper member 33 is provided with a toe portion 33A that can engage with the ratchet wheel 31, and the other end is provided with an arm portion 33B that can come into contact with the rear surface of the second tape holder 13. The stopper member 33 is biased by a spring 34 in the counterclockwise direction in FIG.

Note that here, in the center of the object placement section 3, there is a
A recess 3A extending in the front-rear direction is formed. The concave portion 3A serves to guide the tape 6 being wound around the object A on the placement portion 3 so that the tape tightening operation by the unwinding device 7 can be performed smoothly.

In the above-mentioned apparatus, when binding objects to be bound, the ends of the tape 6 are connected to the first end as shown in FIG.
While being held between the second tape holding bodies 9 and 13, the object to be bound A is pushed in the direction of the arrow and inserted between the guide part 26 on the placing part 3 and the clamping body 27 as shown in FIG. do.

Next, rotate the handle 30 forward to tighten the tightening body 2.
7 is brought close to the rear side of the crimping table 2, and the object A to be bound is compressed between the tightening body 27 and the guide portion 26.
At this time, the toe portion 33A of the stopper member 33 engages with the ratchet wheel 31, so that the clamping body 27 is maintained in a state in which the object A is clamped.

In this case, the stopper member 33
Since it is fixed by meshing with the toe portion 33A, the tightening body 27 can be fixed at any rotational position. Therefore, it becomes possible to appropriately tighten objects of various sizes.

Next, the binding arm 4 is lowered to wrap the tape 6 around the object A. At this time, the excess tape that has become slack due to the lowering of the binding arm 4 is rewound onto the reel 5A by the tape feeding device 5. In this case, since the tape 6 wound around the object A on the placement section 3 is located in the recess 3A of the placement section 3, there is a gap between the placement section 3 and the object A. The reel 5A is not restrained and smoothly reeled back to the reel 5A side. Thereafter, as the binding arm 4 descends, the tape pressing body 15 collides with the tape pressure bonding table 2 via the tape 6, and the adhesive surfaces of the tape 6 wound around the object to be bound A are bonded together. At this time, or after that, when the inclined portion 17A contacts the second tape clamping body 13 and the binding arm 4 descends, the spring 16 is shortened and the tape pressing body 15 is kept in abutment against the tape crimping table 2. The tip shaft portion 13A of the second tape holder 13 is separated from the first tape holder 9 along the cam portion 17A as the binding arm 4 descends.

Further, the inclined cam portion 17A is connected to the second tape holding body 1.
3, or before that, the tip shaft portion 20A of the third tape holding body 20 touches the first tape holding body 9.
Thereafter, as the binding arm 4 descends, the third tape holding member 20 descends while being engaged with the tape holding groove 9A, as shown in FIG. As shown in FIG. 2, it enters between the second tape holder 13 and the first tape holder 9.

In addition, when the second tape holding body 13 moves backward, the arm portion 3 of the stopper member 33 is moved as shown in FIG.
3B and press the toe portion 33A of the stopper member 33.
In order to release the object A from the ratchet wheel 31, the clamping body 27 is rotated back to the rear by the force of the spring 32, and the object A is released from its restraint.

As shown in FIG. 5, when the auxiliary tape holder 25 collides with the first tape holder 9 via the tape 6, the third tape holder 20 also stops descending, and the first
The rotation of the tape holding body 9 also stops. Further, at the same time as or before the auxiliary tape holder 25 collides with the first tape holder 9 via the tape 6, the second tape holder 13 reaches the vertical cam portion 17B, and then the binding arm 4 descends. Then, the spring 23 is shortened, and the auxiliary clamping body 25 is kept in contact with the first tape clamping body 9, and the second tape clamping body 13 is maintained at a constant distance from the first tape clamping body 9. dripping

As the binding arm 4 descends, the cutting blade 18 enters between the first tape holder 9 and the second tape holder 13 to cut the tape 6, as shown in FIG. Also, together with the cutting blade 18, the tape relief rod 1
9 enters between the second tape holder 13 and the tape crimping table 2, and pushes out the end of the tape 6 on the crimping part side between the second tape holder 13 and the tape crimping table 2. Therefore, the end portion of the tape 6 on the crimp portion side is not held again between the first tape holder 9 and the second tape holder 13.

After that, when the binding arm 4 is raised, the cutting blade 18
The tape relief rod 19 returns upward, and the spring 23,
16 returns to the extended state.

After the spring 23 returns to its original stretched state and the auxiliary clamp holder 25 separates from the first tape clamp 9, reverse rotation of the first tape clamp 9 is restricted, so that the third tape clamp Tip shaft portion 20A of body 20
1 rises along the outer periphery of the first tape holder 9 while pressing the tape 6 onto the first tape holder 9, and returns to the state shown in FIG.

By repeating the above operations, it is possible to repeatedly bind objects to be bound.

In the device of the above embodiment, the second tape holder 13 is displaceable with respect to the first tape holder 9;
It may also be a device that is displaced relative to the tape holding body 13. In this case, the third tape holding body 2
0 may also be configured to serve as a clamping control section. Further, the first tape holding body is not limited to one that rotates in one direction.

In addition, the inclined cam surface 17A can be directly connected to the stopper member 3.
The stopper member 33 may be operated by being brought into contact with the arm portion 33A of No. 3.

Further, the means for driving the tightening body 27 is not limited to the above embodiment, and may be moved toward or away from the rear surface of the crimping table in conjunction with the tilting movement or tilting movement of the binding arm 4, for example. In this case, the binding arm 4 and the tightening body 27 may be connected by a ring or the like. Furthermore, the tightening body 27 may be moved toward and away from the rear surface of the crimping table by a foot pedal (not shown). In this case, the tip of the wire wound around the support shaft 29 can be connected to the pedal for indexing.

Furthermore, the first tape holding body may not have a tape holding groove, or may have elastic protrusions on its outer periphery.

(Effects of the Invention) As described above, the present invention allows the objects to be bound placed on the mounting table to be held at any rotational position by providing the object holding means. The tape can be brought close to the object to be bound guide part, and the tape can be tightened in a sufficiently compressed state by both of them, and then the binding arm can be lowered to wrap the tape around the sufficiently tightened object to be bound. , it becomes possible to bundle objects of various sizes in a sufficiently compressed state. Therefore, even objects to be bound that have relatively large internal gaps, such as flower bouquets and vegetable bundles, do not need to be held by hand, and can be bound with sufficient tightening force.
