Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a binding device for wrapping and binding vegetables, flowers, etc. with a binding tape.

(Prior Art) As shown in Japanese Patent Publication No. 57-40008, a binding device generally includes a mounting table 1' disposed at a binding position for objects W to be bound, and a tape holder adjacent to the mounting table 1'. means 2', and tape guide means 5' that approaches and approaches the tape holding means 2' and guides the binding tape 4' pulled out from the wrapping tape 3', is held by the tape holding means 2' via the tape guiding means 5', and a binding tape 4' is stretched between the tape holding means 2' and the tape guiding means 5', and the tape holding means 2' and the tape are held by the tape holding means 2'. The object to be bound W is placed on the mounting table 1' while applying it to the binding tape 4' stretched between the tape guiding means 5' and the tape holding means 2', and the tape guiding means 5' and the tape holding means 2' are brought into close contact with each other. Particularly, the object to be bound W
A binding tape 4' is wound around and bound (see Fig. 5).

(Problem to be solved by the invention) However, in the above-mentioned binding device, by aligning the tape guide means 5' and the tape holding means 2', the objects W to be bound are wound with the binding tape 4'. Since the tape is tied together, when tying up so-called leafy vegetables such as spinach and mustard spinach, there is a risk that the leaves of the leafy plants may be caught between the tape guide means 5' and the tape holding means 2'. In order to prevent the leaf from being caught between the means 2' and 5', great care is taken in placing the leaf on the mounting table 1'. Ta.

The present invention was developed in view of the above circumstances, and its purpose is to prevent leaves from being caught between the tape guide means and the tape holding means when tying up so-called leaves.

(Means for Solving the Problems) In order to achieve this purpose, in the present invention, a mounting table 2 disposed at the binding position of the objects to be bound is provided.
and a tape holding means 15 adjacent to the mounting table 2,
19, and a tape guide means 4A that approaches and approaches the tape holding means 15, 19, and the mounting table 2 is applied to the binding tape held by the tape holding means 15, 19 through the tape guide means 4A.
The objects to be bound placed on the tape guiding means 4A
In the binding device, the mounting table 2 is provided so that the height thereof can be adjusted, and the mounting table 2 is height-adjustable. 2
In addition, an entry regulating member 9 is provided adjacent to the tape holding means 15, 19 and having a front guide portion 9A curved in a direction to wrap the object placed on the mounting table 2, and is detachably provided.

(Function) With the above-described configuration, the entry regulating member 9 attached to the mounting table 2 prevents leaves of spinach or other leafy plants between the abutting tape holding means 15, 19 and the tape guiding means 4A. Entry will be prevented. Furthermore, since the front guide portion 9A of the entry regulating member 9 is curved, it is possible to wrap and hold leafy vegetables that tend to spread and fall apart due to the elasticity of the leaves before being bundled. By adjusting the height of the tape holding means 15 and 19, the objects to be bound can be bound near the tape holding means 15 and 19, so that the tape 6 can be wrapped around the leaves with an appropriate tightening force without causing any slack in the tape 6. be able to. In addition, when tying stalks such as asparagus that are not likely to enter between the tape holding means 15 and 19 and the tape guiding means 4A, they may become a hindrance when placing the objects on the mounting table 2. The entry restricting member 9 can be removed.

(Example) Examples of the present invention will be described below based on the drawings.
In FIGS. 1 and 2, reference numeral 1 denotes a base, and a mounting table 2 for objects to be bundled is provided at the center of the base. A tape crimping table 3 is provided protruding from the top. The mounting table 2 includes parallel links R that are pivotally connected to the side plate parts 1A and 1B of the base 1.
The parallel link R is fixed to a rod passing through a plurality of perforations H provided in the side plate parts 1A and 1B in the height direction, so that the height can be adjusted. A binding arm 4 is pivotally mounted on a base 1 behind the mounting table 2 so as to be movable up and down, and here a tape feeding device 5 is mounted on the base 1 behind the binding arm 4. The single-sided adhesive tape 6 is wound around the reel portion 5A of the tape feeding device 5, and the end of the tape 6 is drawn out toward the arm end portion 4A of the binding arm 4. The tape feeding device 5 feeds the tape 6 to the reel portion 5 as the binding arm 4 is tilted (rotated counterclockwise in FIG. 1).
It has a rewinding device 7 for rewinding to A. 8
is a spring that biases the binding arm 4 in the upright direction.

A guide plate 9 for guiding the objects A to be bundled in a bundle is detachably attached to the mounting table 2 via a concave-convex fitting part 10. Front guide portion 9 of this guide plate 9
A has a curved shape that is compatible with the object to be bound A, and the upper end of the front guide section 9A extends above the tape crimping table 3, and the tape 6 can pass through the center thereof. An opening 9B with a width is formed. The front guide portion 9A serves as an entry restricting means for preventing a part of the object A from protruding toward the tape crimping table 3 side. The guide plate 9 can be replaced with one having an appropriate size and shape depending on the size, type, etc. of the objects A to be bound.

A handle 11 is provided near the arm end 4A of the binding arm 4.
is pivotally connected via a shaft 12, and the binding arm 4 has a shaft 12
An arc-shaped elongated hole 13 centered at is formed, and the handle 11 can be fixed to the binding arm 4 at any angle by a fastening means 14 passing through the elongated hole 13. Therefore, the position of the handle 11 can be adjusted to suit the user, and the handle 11 can be folded when not in use or stored, thereby reducing the size of the entire device.

A first tape holding body 15 is provided on the base 1 in front of the tape crimping table 3. As shown in FIG. 4 A, B, and C, this first tape holding body 15 is
It is supported rotatably only in the clockwise direction in FIG. 1 via a one-sided clutch 17 on a support shaft 16 fixed non-rotatably between the side plates 1A and 1B of the base 1. This first tape holding body 15 has a cylindrical shape,
Two elastic protrusions 18 are protruded in the shape of an arc (in this case, an annular shape) from the surface that serves as the tape clamping surface.

A second tape clamping body 19 is provided between the first tape clamping body 15 and the tape crimping table 3, and the second tape clamping body 19 cooperates with the first clamping body 15 to clamp the end of the tape 6. This second tape holding body 19 is provided so as to be able to come into contact with and separate from the rear surface of the first tape holding body 15,
Moreover, it is biased toward the first tape holding body 15 by a spring 20.

A tape pressing body 21 is attached to the arm end 4A of the binding arm 4 via a spring 22 so as to be movable forward and backward. This tape pressing body 21 plays the role of adhering the adhesive surfaces of the tape 6 together in cooperation with the tape crimping table 3. Here, this tape pressing body 21 is designed to abut against the upper surface of the tape crimping table 3. However, it may be formed so as to descend along the front or rear surface of the tape crimping table 3.

A clamping control section 23 is provided on the arm end 4A near the tape pressing body 21 to separate the second tape clamping body 19 and the first tape clamping body 15 from each other. Here, the clamping control section 23 consists of an inclined cam 23A and a vertical cam section 23B.
Both cam portions 23A and 23B act on the two tape clamping bodies 19 in sequence and serve to separate the second tape clamping body 19 from the first tape clamping body 15.

The arm end 4A of the binding arm 4 is provided with a cutting blade that cuts the tape 6 between the first and second tape holders 15 and 19 when the first and second tape holders 15 and 19 are separated from each other. 24 is fixedly provided, and a tape release rod 25 for pushing down the tape 6 is fixedly provided between the cutting blade 24 and the tape pressing body 21. Note that when the tape pressing body 21 is formed to descend along the front and rear surfaces of the tape crimping table 3, the tape relief rod 25 may be omitted.

A third tape clamp 26 is provided at the arm end 4A of the binding arm 4 to clamp the tape 6 in cooperation with the first tape clamp 15. Here, the third tape holder 26 is attached via a shaft 27 to an intermediate portion of a support rod 28, and the support rod 28 is attached via a spring 29 to the arm end portion 4A so as to be movable forward and backward. The third tape holding body 26 is biased clockwise in FIG. 1 by a spring 30. An auxiliary clamp holder 31 that can collide with the first tape clamp holder 15 is attached to the tip of the support rod 28.
may be omitted.

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.
The object to be bound A is pushed in the direction of the arrow while being held between the second tape holders 15 and 19 and inserted into the guide plate 9 on the mounting table 2. At this time, the objects A to be bound before being bound are guided by the guide plate 9, so that the shape of the objects A is not significantly distorted.

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 by the tape feeding device 5. tied arm 4
When the tape presser 21 is lowered to the position shown in FIG. 4A, the tape presser 21 abuts against the tape pressure bonding table 3, and the adhesive surfaces of the tape 6 wound around the object to be bound A are bonded together. At this time, or thereafter, when the inclined cam 23A contacts the second tape holding body 19 and the binding arm 4 descends, the spring 22 is shortened and the tape pressing body 2
1 is maintained in abutment with the tape crimping table 3, and the tip shaft portion 19A of the second tape clamping body 19 moves along the cam portion 23A as the binding arm 4 descends.
It is separated from the tape holder 15.

Further, the inclined cam 23A is connected to the second tape holding body 19.
When or before contacting the third tape holder 26, the tip shaft portion 26A of the third tape holder 26 touches the first tape holder 15.
Then, as the binding arm 4 descends, the third tape holding body 26 descends while holding the tape 6, and the second tape holding body 19 and the first tape holding body 15. At this time, the first tape holder 15 receives the pressing force of the third tape holder 26 and rotates clockwise.

As shown in FIG. 4B, the auxiliary clamp holder 31
The tape 6 is attached to the elastic protrusion 18 on the tape holding body 15.
When collided through the third tape holding body 26
The lowering of the tape holder 15 also stops, and the rotation of the first tape holder 15 also stops. In addition, the auxiliary clamp holder 31 has the elastic protrusion 18
At the same time or before colliding with each other via the tape 6, the second tape holding body 19 moves against the vertical cam portion 23B.
reach. Thereafter, when the binding arm 4 descends, the spring 29 is shortened and the auxiliary clamp holder 31 is maintained in abutment with the first tape clamp 15, and the second tape clamp 19 is held against the first tape clamp 15. and are kept at a constant distance.

Then, as the binding arm 4 descends, the cutting blade 24 cuts the first tape holder 1 as shown in FIG. 4C.
5 and the second tape holding body 19, and the tape 6
cut. In addition, the tape release rod 25 as well as the cutting blade 24 is connected to the second tape holding body 19 and the tape crimping table 3.
and the end of the tape 6 on the crimp part side with the second
The tape is pushed out between the tape holding body 19 and the tape crimping table 3. Therefore, the end of the tape 6 on the crimping portion side is not held again between the first tape holding body 15 and the second tape holding body 19.

After that, when the binding arm 4 is raised, the cutting blade 24
The tape relief rod 25 returns upward, and the spring 29,
22 returns to the extended state.

Until the spring 29 returns to its original stretched state, the auxiliary clamp 31 and the third tape clamp 26 are pressed against the first tape clamp 15 by the spring force of the springs 29, 30, etc. Therefore, the tape 6 is held firmly between the auxiliary/third tape holder 31, 26 and the elastic protrusion on the first tape holder 15. Note that when the binding arm 4 is raised, the tape 6 is pulled out from the tape feeding device 5 as the binding arm 4 is raised. That is, although a tensile force is generated at the new end of the tape 6, the tape 6 is pressed against the first tape holder 15 by the auxiliary holder 31 and the third tape holder 26, so it does not come off. There's nothing to do. Note that the tape 6 can be sufficiently prevented from coming off only by the pressing force of the third tape holder 26.

After the spring 29 returns to its original stretched state and the auxiliary clamp holder 31 separates from the first tape clamp 15, the reverse rotation of the first tape clamp 15 is restricted, so the third tape clamp 26 tip shaft portion 26
In A, the elastic protrusion 18 on the first tape holding body 15 rises along the outer periphery of the elastic protrusion 18 while pressing the tape 6. In this way, while the third tape holder 26 is rising along the first tape holder 15, the tape 6 is elastically held between the tip shaft portion 26A of the third tape holder 26 and the elastic protrusion 18. Since the tape 6 is held between the tapes 6 and 6, the tape 6 will not come off or be cut.

Then, when or before the third tape holder 26 separates from the first tape holder 15, the second tape holder 19 returns and the first tape holder 15
Since the tape 6 is clamped between the upper elastic protrusion 18, the clamping operation of the tape 6 will not be interrupted during the binding operation.

By repeating the above operations, the object to be bound 26
The tying work can be performed repeatedly.

(Effects) As described above, in the present invention, leaves of spinach, etc., enter between the abutting tape holding means and tape guiding means by the entry regulating member attached to the mounting table. Therefore, it is possible to prevent the leaves of the leaf from being caught between the tape guide means and the tape holding means during so-called bundling of the leaf.

Furthermore, since the leaves can be bound with an appropriate tightening force, the tape can be wrapped around the leaves to avoid damaging the leaves, and the tape can be wrapped around the leaves to avoid sagging, so there is no gap between the leaves and the tape. This eliminates the problem of the objects being bound coming off the tape during transportation.

In addition, when binding stems such as asparagus that are unlikely to enter between the tape holding means and the tape guiding means, remove the entry restricting member that gets in the way when placing the objects to be bound on the mounting table. Therefore, when tying so-called stems, it is possible to perform the tying work smoothly as in the past.
