Description

Detailed Description of the Invention (Field of Industrial Application) The present invention is applicable to tape binding machines, particularly for binding tomato stems, grape vines, etc. to support rods, support shelves, etc. The present invention relates to a tying machine useful for closing the opening of a bag placed over fruit.

(Prior Art) For example, when cultivating grapes by placing grape vines on grape trellises, there is a task of tying the vines to the grape trellises.

Unlike normal packing, this binding cannot be done while moving the grape vines. When this tying work is performed using a hand-held tying machine (scissors-like), the operation of this tying machine is as follows:
First, open the scissors and pull out the tape.
It is necessary to wrap the tape around the vine and close it to bond the tape together, to cut the tape after bonding, and after cutting, to open the scissors and remove the binding machine from the vine.

For example, in the binding machine described in Japanese Patent Publication No. 52-42689, as shown in Figs. 13 to 15, when tying grape vines to a support shelf, first
01 is lightly squeezed and compressed, the pedestal 103 of the base plate 102 and the clamping body 104 come into contact as shown in FIG. 14. Subsequently, the actuating piece 105 presses the push rod 106 and pushes it downward. The rear end 106a of the push rod 106 separates from the locking protrusion 107a of the case 107 against the biasing force of the spring 108, and the tape holding plate 109, which had been pressed against the tip 106b of the push rod 106, As the push rod 106 enters the vertical hole 107a of the box 107 and retreats, it moves toward the receiving plate 110 and clamps the tape A. After that, when the force on the handle 101 is loosened,
The base plate 102 and the clamping body 104, which were in contact with each other, are separated with the tape A being clamped between the tape clamping plate 109 and the receiving plate 110, and the tape A is moved to the tape guide 1.
Pull out from 11.

After the tape A is pulled out, the object B to be bound is inserted between the base plate 102 and the clamping body 104, such as a stem or the opening of a bag as shown in FIG.
squeeze and compress. When the handle 101 is compressed, the tape A is pressed between the pedestal 103 of the base plate 102 and the clamping body 104, and the object B is bound. When the handle 101 is further tightened and compressed, the cutting blade 113 provided at the tip of the press body 112 descends to cut the tape A at the tip side of the pedestal 103, and the actuating piece 105 moves the push rod 1
06 downward and the clamping plate 109 is moved to the receiving plate 11.
Release tape A by moving it away from the 0 side. The pressing force of the handle 101 is relaxed, the clamping portion held between the base plate 102 and the pedestal 103 is released, and the bound object is taken out.

(Problems to be Solved by the Invention) In the conventional binding machine as described above, the leading end of the tape is held between the clamping plate 109 and the receiving plate 110, and the operation of feeding out the tape A and the binding by the fed out tape A are performed. In order to perform operations such as binding things together,
The problem is that it is necessary to operate the handle 101 twice, which not only makes the tying work troublesome, but also that one worker's arm gets tired quickly when tying the tying continuously, resulting in a significant drop in work efficiency. The point was hot.

(Means for Solving the Problems) In order to solve the above problems, the present invention is provided with a pair of operating levers and a pair of binding arms rotatably provided on a support shaft, and a binding tape is attached to one of the binding arms. A cutting device for cutting is rotatably provided, and a clamping device for clamping and releasing the binding tape is provided on the other binding arm so as to be reciprocally movable. Then, between the operating levers and both binding arms, the turning force of the operating lever causes one binding arm to first approach the other binding arm, then stand still, and then move away from the other binding arm. First and second pin cam engaging means are provided to rotate, and when the other binding arm is separated, the third pin cam engaging means rotates and stands up the cutting device, and the clamping device is released. A fourth pin cam engaging means is provided.

(Function) With this configuration, when no grip force is applied to the operating lever, the tape is stretched between both binding arms. Then, when the operating lever is squeezed, one binding arm approaches the other binding arm to paste the bound tape together, and then, while the one binding arm remains stationary, the other binding arm opens. At this time, the tape grip is released and the cutting device stands up.

The above operations are performed by simply squeezing the operating lever.

Next, when the gripping force is released, the operating lever returns to its original position, and the reverse operation of the above operation is performed to return to the original state.

(Example) Hereinafter, an example in which the present invention is applied to a tape binding machine using adhesive tape will be described in detail.

In FIG. 1, reference numerals 1 and 2 indicate a pair of operating levers.

The operation of this embodiment configured as above will be explained next.

The relationship between each pin and the cam when the operating lever 2 is operated from A to B will be explained using FIG. 16.

First pin cam engagement means 29 (hereinafter referred to as pin 29D)
) drives the arm 8. The second pin cam engagement means 30 (hereinafter described as pin 30D) drives the arm 9. The third pin cam engagement means 33 (hereinafter described as pin 33D) is
The cutting drive rod 17 is driven, thereby cutting the cutting device 1.
Operate 3. The fourth pin cam engagement means 34 (hereinafter described as pin 34D) is connected to the clamping drive rod 2.
6 to operate the clamping piece 24.

First, when the operating lever 2 is in the A position, each pin and cam are in the position shown in the figure (dotted chain line in the figure). This state is the state shown in FIG. 1, in which the arm 9 is used to pull out the tape 5 to tie up, for example, a grape vine.

Next, push the operating lever 2 to positions A to B,
The pin 29D is pushed downward along the cam hole 29A while being pushed by the cam hole 29B against the elastic force of the spring 32, and the arm 8 moves downward along the cam hole 29C while moving the support shaft 3. rotated around the center.

On the other hand, the pin 30D moves along the line A through the cam holes 30B and 30A against the elastic force of the spring 31, and only moves along the cam hole 30C of the arm 9, and the arm 9 remains in a stopped state. keep.

The pin 33D is connected to the cam holes 33A, 33B, 33C.
In this state, the rotational force of the operating lever 2 does not act on the pin 33D.

The pin 34D is also stopped in the cam hole 34E so that the rotational force of the operating lever 2 is not applied to the pin 34D due to the cam hole 34B.

This state is the state shown in FIG.
is crimped and the tape 5 is attached. The end of the tape 5 is held by a holding piece 24, and
The cutting device 13 is not activated.

Next, when the operating lever 2 is moved to the positions RO to H, the pin 29D is already in the cam hole 29B at the previous position RO.
Since the operating lever 2 is located at the lower end of the operating lever 2, no rotational force is applied to the operating lever 2, and the operating lever 2 remains in the same position due to the spring 32. Therefore, the arm 8 also stops at the same position.

The pin 30D is pushed down by the cam hole 30B against the elastic force of the spring 31, and moves downward along the cam hole 30A. This causes the arm 9 to rotate.

The pin 33D is pushed by the cam hole 33B, moves within the cam hole 33A, drives the cutting drive rod 17, and raises the cutting device 13.

The pin 34D is given a rotational force by the cam hole 34B and moves within the cam hole 34A. Since the ends of the cam holes 34A and 34B are bent as shown in FIG. 10, the pin 34D moves along the shape of the cam holes and drives the clamp drive rod 26.
As a result, the clamping piece 24 is held by the spring 28.
is separated from the crimp body 11.

When the operating lever 2 is in the position C, as shown in FIG. 11B, the arm 9 is rotated while the arm 8 remains stationary, and the grip on the tape 5 is released.

For example, if you remove the tape binding machine from the grape vine after tying the grape vine A,
The tape 5 is cut by the cutter blade 15 of the cutting device 13 which is standing upright.

Then, the cut end of the tape 5 is brought into a protruding state by the tape guide device 12.

Next, when the grip force on the operating lever 2 is released, the spring 4 returns to the state shown in FIGS. 11-1 and 1. Of course, in the device of the present invention, both operating levers 1 and 2 can be operated with one hand.

Note that by appropriately setting the circumferential length of the cam hole 33B, the cutting operation start timing of the cutting device 13 can be appropriately set, and the related operations of each part can be performed smoothly.

FIG. 12 shows another embodiment of the present invention,
In the drawings, the same reference numerals as in FIGS. 1 to 11 indicate the same components as in the above embodiment. This example is characterized in that a cam plate 35 that engages with a pin 34D is provided between both plate parts 1A and 1B of the operating lever 1, and this cam plate 35 is rotatably supported on the support shaft 3. A pin 36 attached to the cam plate 35 engages with a pin hole 37 formed in both plate parts 1A, 1B in a slightly elongated hole shape in the circumferential direction. Here, the cam plate 35 may be urged counterclockwise in the figure with respect to both plate parts 1A and 1B by the spring 38. The cam plate 35 is formed with a corner portion 35A that can be engaged with the pin 34D.

In the above configuration device, when the upper binding arm 9 starts to rotate clockwise with respect to the operating lever 1, that is, when the upper binding arm 9 starts to separate from the lower binding arm 8 after binding the tape, the clamping drive rod 26 The pin 34D attached to the upper binding arm 9 moves toward the arm end side along the inclined portion 34A' of the cam hole 34A while pushing the cam plate 35 clockwise. Therefore, this operation is similar to that of the apparatus of the above embodiment.
However, when the upper binding arm 9 then rotates counterclockwise toward the lower binding arm 8, that is, when the clamping piece 2
4 enters the tape end clamping operation, pin 34D
remains engaged with the outer periphery of the corner portion 35A of the cam plate 35, and is displaced only counterclockwise with respect to the operating lever 1 together with the cam plate 35 without following the inclined portion 34A' of the cam hole 34A. 9 approaches, the pin 36 comes into contact with the left end of the cam hole 37 and the cam plate 35 stops, and as a result, the pin 34D
is detached from the corner portion 35A of the cam plate 35 and falls toward the support shaft 3, and the clamping piece 24 instantly enters the tape clamping operation from the tape release state. That is, clamping piece 2
Since the tape 4 is kept open until just before the binding arms 8 and 9 come close to each other, it is easy to grip the end of the tape 5, and there is an advantage that there is no chance of a pinching error.

Although the present invention has been described above with reference to an example in which the present invention is applied to a tape binding machine that uses adhesive tape, the present invention is not limited to this. It's okay. In this case, a staple supply means may be provided at the crimping bodies 10 and 11. Further, as the binding tape, a type of tape that becomes sticky when crimped may be used.

(Effects of the Invention) Since the present invention has the above-mentioned configuration, each time the pair of operating levers is rotated toward and away from each other once, the bound end of the tape is crimped, cut, and a new tape end is clamped. It is possible to repeat one cycle of a series of tape binding operations, such as binding tomato stems, grape vines, etc. to support rods, support shelves, etc., and holding bags to cover fruits such as pears to branches. You will be able to perform tasks easily and reliably.

In addition, even when one worker has to repeatedly perform tying operations, he only needs to operate the operating lever once for each tying operation, which is half the number of operations required with conventional devices. This reduces arm fatigue and allows you to work faster, greatly improving work efficiency.
