Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a method for automatically tying the end of a string (or thread) wrapped single or double over an object to be tied. This invention relates to a device for untying and tying into a single knot that can be untied by pulling one end of a string. As shown in FIG. 15, the knot formed by the device of the present invention is
Since it is a slightly modified single knot that can be unraveled, it is hereinafter referred to as a single ring knot. The inventor of this application has already proposed this type of binding machine with different functions depending on the purpose, but the demands of users are diverse.For example, in agriculture and gardening, for example, tying grape vines to shelves It can be used for multiple purposes such as tying seedlings to a support or tying the opening of a bag filled with things, and the knot is formed in contact with the object to be tied, so it can be used to tie things fairly tightly. Since there is a need for a device that can perform the following tasks and operate reliably with fewer failures, the present invention provides a bundling device that meets these objectives.

[Conventional technology]

Conventionally, there are only a few proposals for mechanical devices for pulling and tying, and there are even fewer proposals for mechanical devices that are hand-held and that can be brought to the object to be tied to achieve the purpose of tying. The inventor of this application has proposed patent No. 1053364 (Japanese Patent Publication No. 55-48006).

They are built into each other so that they work together organically.

[Effect]

To explain the operation of the apparatus of the present invention having the above structure, first, as a preparation, the cord K at the tip of the apparatus is pulled out, wrapped around the object to be bound, and the end of the cord is hooked onto the hook H (FIG. 4).

The string passes through the string passage 60 from the storage case 61, passes through the long groove 19, and then enters the string passage 2 of the string feeding rod 21.
After the string enters the string 4 and once comes out, it is advanced from the tip of the string through the thin hole 23.

Therefore, when the lever 50 is pulled toward the handle 4 by grasping the handle 4 and the lever 50, the protrusion 57 of the cam 33 engages with the contact roller 56 of the limit switch 55 of the motor M via the connecting rod 51. The rotating cylinder 26 is connected to the rotary cylinder 26 via the bevel gears 29, 29', the worm 28, and the worm wheel 27 that are interlocked with the motor.
This rotation causes the rotary cylinder 26 to move toward the front side of the upper end of the pair of rotary plates 8 and 9 mounted in the leading fork 5 and 5' of the shaft center body 1. In this step (Fig. 7), a movement is made to wrap the string around the leading end of the axle, but the part of the wound string that touches the bottom of the leading end 5, 5' is a mushroom. Since it forms a tapered slope, it slides down this slope to the tip (Fig. 8) and forms a string ring R (Fig. 9).

By the way, the following action is performed before the rotary cylinder 26 rotates twice. This is because the cam crest 3 of the cam 33 occurs before 1.5 rotations after the rotating cylinder has made one rotation.
5 is attached to the lever 38 via a spring 37 attached to the lower part of the lever 38, and a connecting rod 4 pivotally connected thereto.
0, and the string payout rod 21 attached via the pedestal 20 attached to its tip is advanced.
At this time, the concave notch 22 of the string feeding rod is connected to the hook 1 of the hook 13 installed in the head 12 of the rotating body 11.
It comes right below 4. In this state, the lower part 37' of the leaf spring 37 slides on the upper surface 35' of the cam ridge 35,
The lever 38 temporarily stops its rotation, and accordingly the string payout rod also temporarily stops at the aforementioned position.

Due to the advancement of the string feed-out lever 21, a string portion K ₁ extends from the string hole 23 of the lever to the right side of the object A to be bound.
is bent like a hairpin at 65 points (Figure 11b),
Inside this fold, there is a string tip K ₂ , that is, a rotating plate 8,
After turning up 9, insert the center part of the string that reaches the hook H.

Next, a moment later than the engagement between the cam ridge 35 and the lever 38, the lever 34 is pushed in the direction of the arrow by the protruding pin 54 on the cam 33.

A connecting rod 45 is therefore pivotally connected to the lever 34;
The rotating body 11, to which the tip of the connected connecting rod 18 is connected via the mounting hole 17, is rotated in the direction of arrow H about the support shaft 7 through the connecting tool 48 at the tip (see FIG. 3). ), hook 1 planted on its head 12
3 is lowered, and the lowering causes the hook 1 of the hook to be lowered.
4, at the position of the concave notch 22 of the string payout rod 21, pull down the string at that part, eventually forming a loop L, and pass through the string loop R and pull it down. Ru. Furthermore, as the rotation of the rotating body 11 progresses, the pin 12' installed on the upper surface of the rotating body 11 rotates downward, pressing down the connecting rod 10 that connects the rotating plates 8 and 9. When 9 is rotated counterclockwise around the support shaft 7, its tips 8' and 9' also sink downward, and finally fall further below the string ring R.
The strap ring R is released from the rotating plate (FIGS. 14 and 15).

In this state, the rotating body 11 continues to rotate,
The loop L also continues to descend, while the rotary cylinder 26 is in the middle of its final 1/2 to 1/4 turn, and at this stage the knot is tightened. Further, at this final stage of rotation of the rotary body 11, the string is cut by the blade portion 16 at its tail and the cutter device 63 on the machine stand.

When the rotation of the cam 33 reaches its end, the lower end 37' of the leaf spring 37 attached to the lower part of the lever 38 comes off the inner end of the cam ridge 35 and falls into the valley 33' of the cam. In this way, the engagement between the lever 38 and the cam ridge 35 is instantly released, and the lever 38 is disengaged from the connecting rod 4.
The force of the spring 43 engaged with the connecting rod quickly returns to its original position.

At this time, the rotary cylinder 26 completes two rotations, and the hook H
will return to its original position, so when you release your grip on the handle, the lever 50 will return to its original position due to the force of the leaf spring 50', and the lever 34 will also return to its original position together with the connecting rod 45 due to the compression spring 47. Thus, one actuation will ends.

An axle pin 36 is provided above the axle pin 32, and a lever 38 is pivotally connected to the axle pin 36. A long window 39 is provided in the upper part of the lever, and a leaf spring 37 is attached to the lower end of the lever. It is in contact with the lower rear surface of the lever 38. Therefore, when the lower end 37' of the leaf spring is pushed in the direction of arrow 2, the lever 38 is rotated in the direction of arrow RO, but when the lower end is pushed in the opposite direction to arrow d, the spring is rotated against the shaft pin. The lever 38 is configured so that it simply rotates around the lever 36 without resistance and no external force is applied to the lever 38. The two levers 34 and 38 are each connected to a connecting rod 40.

The binding device of the present invention has the above-mentioned configuration, and its operation will be explained below. First, as a preparatory step (Fig. 4, Fig. 5), the tip of the barrel of this device is
When the string K is in contact with the object A to be tied, or with a natural gap (the figure shows a case where there is a gap), manually pull the string K out from the tip of the string payout rod 21. After passing it around the back of the bundle A, the end of the string is hooked onto the hook H provided on the front left side of the rotary tube 26. When the preparatory work is completed, the fingers of the hand gripping the handle 4 are tightened and the drive lever 50 is pulled toward the handle, thereby rotating the motor M and the cam 33 via the connecting rod 51. Therefore,
First, to describe the action of the rotating barrel 26, the protrusion 57 of the cam 33 contacts the contact roller 56 for driving the motor M, rotates the motor, and the bevel gear 2
9, 29', worm 28, worm wheel 2
The rotary cylinder 26 is rotated clockwise (in the direction of arrow C) via the rotary cylinder 7, but by providing a limit switch 55, the rotary cylinder is regulated to automatically stop after two rotations. In addition, the rotating cylinder is approximately 1
The important operation of this device is achieved before and after making one and a half rotations, and we will explain from the starting state of the rotating cylinder shown in Figs. 4 and 5 to Figs. 6 and 7, which have made one and a half rotations. When the rotary tube 26 rotates from the state shown in FIGS. 4 and 5, the end of the string K held by the hook H passes over the upper surface of the front end of the shaft core 1 as the rotary tube rotates. Figures 6 and 7 show the state in which the hook H has been turned to the right after making a half turn. moreover,
As the cylinder continues to rotate, the string (not shown) passes through the bottom surface of the shaft 1 and the end of the string comes to the starting position (Fig. 4), but when it continues to rotate for another half turn, it reaches the position of the hook H. moves to the right side of the device and assumes the position shown in FIG. Through this one and a half rotation, the string part that is stretched over the bottom of the tip of the shaft center body 1 has a curved surface 5 shaped like the bottom of a ship.
Slide a and move toward the tip of the mushroom-shaped part,
It reaches behind the tips 8', 9' of the two rotating plates 8, 9 and forms a string ring R. Figures 8 and 9 show this state, and Figure 9 (b) shows only the string. The reason why the string slides forward along the bottom of the boat is because the end of the string is held in the hook H, and the length of the string between the left end of the object A and the hook H is approximately constant (fourth, fourth (Figure 9), this is because the string tends to be pulled by the hook.

Second, to describe the operation of the cam until the rotating cylinder 26 rotates approximately one and a half rotations and the operation of the string feeding rod 21 that is linked to the lever 38, the thread 35 of the cam 33
The lower part 37' of the leaf spring 37 that engages with the rear surface is pressed as the cam rotates, and acts to rotate the lever 38 forward in the direction of arrow B, thereby causing the connecting rod 40 interlocked with the lever to rotate. As the string is moved forward, the string feeding rod 21 itself attached to the string feeding rod holder 20 connected to the tip of the connecting rod 40' moves forward, and as shown in FIGS. 10 and 11, the string feeding rod 21 itself moves forward. The tip of the rod reaches the tip 12' of the head 12 of the rotating body 11, and the concave notch 22 of the string feeding rod reaches the head 12 of the rotating body.
It is located directly below the hook 14 of the hook planted in the. At this time, the lower part 37' of the leaf spring 37 comes to slide on the curved surface 35' of the cam ridge 35, the rotation of the lever 38 is stopped, and the string payout rod is also stopped. In this state, the string portion K ₁ extending from the string hole 23 of the string feed-out rod to the right side of the object A to be bound is bent into a hairpin shape at 65 points, and the string tip K ₂ , that is, the rotating plate 8, is bent at 65 points. ，
After wrapping No. 9, insert the approximately center part of the string that reaches the hook H.

Thirdly, to describe the actions of the lever 34, the connecting rod 45, and the rotating body 1 that interlock with the lever 34, the lever 38 is provided protrudingly on the surface of the cam 33 at or just before the lever 38 stops rotating. protruding pin 5
4 engages with the lever 34, presses it in the direction of arrow D, and rotates it backward.
8 is retracted, and the tip of this connecting rod 18 is fitted into the mounting hole 17, so that the rotating body 11
is rotated about the support shaft 7 in the direction of the arrow H, and the hook 13 implanted in the head 12 is lowered. As the hook is lowered, the hook 14 of the hook is exposed from the string hole 23 at the tip of the string paying out rod 21, and the hook 14 is exposed from the string hole 23 at the tip of the string paying out rod 21, and the hook 14 is located directly above the concave notch 22 of the string letting out rod 21, as described above. The string portion that passes through the side surface of the notch 22 and reaches the hairpin-shaped bent part 65 is pulled down at the position of the concave notch.

Thus, the string loop L formed by the hook 14 is pulled down through the loop of the string loop R.

Furthermore, when the hook 14 starts pulling down the string, the rotating plates 8 and 9 also rotate about the pivot 7 after a moment's delay, as will be described later, and the leading end 8 of the rotating plates around which the string was wrapped around. ', 9' are lowered to release the string ring R formed in that part (string ring opening mechanism). In this operation, a pin 12' projecting obliquely from the upper slope of the rotating body 11 rotates downward as the rotating body 11 rotates (FIG. 3), and the rotating plates 8 and 9 are rotated. The connecting rod 10 to be coupled is pressed down to rotate the rotating plate downward, but since the pin 12' and the connecting rod 10 are configured to have a small gap, the rotating plate 8,
This results in a momentary delay compared to the movement of the rotating body 11 in step 9.

The cam 33 continues to rotate, the rotational movement of the rotating body 11 continues, and the loop L continues to descend, while the rotating cylinder 26
Since the rotation continues, the string end K is still pulled by the hook H, tightening the knot.

At this time, the lower end leaf spring 37 of the lever 38 on the handle 4 falls into the valley 33' of the cam 33, so the pressure on the lever is released, and the connecting rod 40 rapidly retreats due to the contracting force of the spring 43 (first
2, Figure 13). At this time, the rotation of the cam 33 reaches its limit and the rotation of the rotating body 11 reaches its final stage, and the blade 62 at its tail engages with the cutter 62' to cut the tail end of the string.

In addition, the rotary cylinder 26 also completes two rotations, and the hook H
reaches its original position, but during this time the knot in the string is tightened.

The above is a movement performed by tightening the lever 50 attached to the handle, thus completing the string tying and cutting the string end, as shown in FIG. The binding action is completed. When the grip on the lever 50 is loosened, the lever is released by the action of the spring 50', and the cam 33 returns to its original position.At the same time, the connecting rod 45 returns to its original position by the repulsive force of the spring 43, and rotates. The moving body 11 and the rotating plates 8 and 9 return to their original positions, and the lever 34 on the handle 4 also returns to its original position. Needless to say, the movement by clenching the lever is completed in a very short time.

〔Effect of the invention〕

Since the device of the present invention has the above-mentioned configuration, the configuration of the device is simplified and the operation of each part is also simplified. The knot is naturally formed near the object to be tied, and this has the effect of ensuring that the object to be tied is securely bound.
This is because the structure of the knot is such that the leading end has a mushroom shape as shown in FIG. In addition, the device as a whole is compact, has fewer parts, and has great economic advantages such as lower costs.
