Description

[Detailed Description of the Invention] Binding machines have been put into practical use for items that have a certain shape, or for items that are securely wrapped such as luggage, and are useful for saving labor, but they are useful in other fields. That is, when the object to be bound is of an irregular shape or when the target is a tree, the work still relies on manual labor and is inefficient.

The present invention relates to a device that can easily and reliably bind objects of any shape in one operation while the binding machine itself is held in hand. This is a highly labor-saving device that enables binding work that was impossible with conventional large tying machines, such as tying up saplings, props for growing seedlings, and other stakes.It does not require skill and can be done with one hand. It has the advantage that it can be easily carried, it can be worked in any place, and it does not require much effort.

The thread tying machine of the present invention forms a ring at the end of the thread string, and the string portion following the ring is pulled into the ring in a loop shape and tightened to form an untied knot, and the end of the thread is pulled. If you do, the knot will be undone,
This knot is suitable for the above applications.

An example of implementing the present invention will be described with reference to the drawings.

First, the structure of the machine will be described with reference to Figures 1, 2, and 3. 1 is a bobbin case with a built-in winding thread or cord 1', 2 is a machine body, and as shown in Figure 1, inside the machine body 2, A metal guide 3 is provided at the front part of the body, and a metal guide 4 is provided at the rear part, and a cylinder body 5 is rotatably mounted between the front and rear metal guides. The cylindrical body 5 itself is composed of a front body 5' and a rear body 5'', as shown in FIG. The rear body 5'' has a notch l formed in the cylinder wall into which the protruding body p fits. It forms a cylindrical body and is rotatable as a unit, and at the same time, the front body 5' is configured to be movable back and forth relative to the rear body 5''.

The front body 5' is designed to be able to advance toward the front body from the rear body by a predetermined length in the axial direction. 6 is a cylindrical cam that is fixed to the fuselage with a fixing screw 2'.
The cylinder 5 passes through the cam 6.

7 is a gear fitted onto the rear body 5'' of the cylindrical body 5.

Reference numeral 8 denotes a string guide pawl attached to the tip of the front body 5' of the cylindrical body 5, and numeral 9 denotes a guide groove cut so that the string can be easily caught on the guide pawl. 10 is a bell hook attached to the tip of the hook rod 10' inserted into the cylinder 5, 11 is its hook portion, and 12 is a bellow, which is normally opened as shown in Figure 1 by the action of a spring. in a state. Reference numeral 13 denotes a disk attached to the rear part of the front body 5' of the cylindrical body 5, on which a small shaft 14 is protruded as shown in the figure. 15 is pivotally supported, and the front body 5' of the cylinder 5
The engaging roller 15 is always pressed against the cam ridge 6' of the cylindrical cam by the pressing force of the spring 16 incorporated therein. In addition, on the right side of the mounting position of the disk 13 on the cylinder 5,
As shown in Fig. 1B, the front body 5' and the rear body 5'' are integrally engaged with each other at the uneven engagement portion formed on the cylinder itself, but the disk 13 is moved to the left in the figure by the action of the cam. As it moves, the front body 5' can move away from the rear body 5'' and advance to the left. 17 is a bevel gear which meshes with a gear attached to the rear body 5'' of the cylinder 5, 18 is a pinion integrally constructed with the bevel gear, and 18' is a support shaft attached to the machine base. 19 indicates the metal of the shaft. 19 is a rack built into a groove provided in the lower part of the machine body 2, which meshes with the pinion 18 and directs the linear movement of the rack to the cylinder 5 through the bevel gear 17 and the gear 7.
gives rotational motion to. At one end (right end in the figure) 19' of the rack, there is a connecting rod 20 at right angles to the rack.
is fixed, and the connecting rod has a passage hole through which the other end of the pull shaft 22 of the drive handle 28 that moves in the axial direction passes through the passage hole 21 provided in the metal guide 37 attached to the fuselage 2. 25, a collar 23 is attached to the front end of the shaft 22, and a spring 24 is attached between the collar and the connecting rod 20. There is also a hook rod 1 on the connecting rod 20.
Passing hole 26 through which the other end of 0' (right side in the figure) is inserted
This passage hole is preferably provided with an appropriate device so that the hook rod 10' can freely move in the axial direction, but cannot rotate. For example, the shaft is provided with a key groove, and the passage hole is also provided with a recessed notch so that the two can be slidably engaged with a key (not shown). Note that 27 is a collar attached to the end of the hook rod 10'.

29 is a protective cover provided to make it easier to tie the strings and to prevent objects to be tied from coming close to the tip of the hook and interfering with its operation, and its both ends are fixed to the metal guide 3 29' , 29'. Reference numeral 30 denotes a cut groove (FIG. 7) for connecting the object to be bound and the string. K is a string cutting blade fixed to the metal guide 3, 31 is a string clamp (Fig. 5) provided to hang the end of the string after it has been hooked on a bundled object, and 32 is a drawer. This is a string guide having a guide hole 32' through which a string is passed.

Next, the hook rod 10' is inserted into the cylindrical body 5, as shown in FIG.
Fits correctly in a slidable manner inside the
The tip portion 4 of the hook rod 10′ in front of the expanded diameter portion 41
2 is formed so that its diameter is smaller than that of the expanded diameter part, and the boundary between the two forms a step, and the smaller diameter of this tip part means that the flesh part of the front body 5' of the cylinder body 5 is formed thicker inward.
The two are configured to be slidably fitted together. Then, the spring 33 connects with the expanded diameter portion 41,
Since the spring 33 is compressed and inserted between the spring cap 34 screwed to the end of the rear body 5'' of the cylinder 5, the spring 33 always acts to push the hook rod 10' to the left in the figure. However, the hook rod is restrained by the rear end of the thick part B of the front body 5' of the cylindrical body and maintains the state shown in FIG. When the rod is pulled to the right in the figure, the hook 10 provided at the tip of the rod is pulled into the front body 5' of the cylinder (FIG. 12).

The operation of the binding machine of the present invention having the above-mentioned configuration will be explained. As shown in Figure 4, hold the body 2 with one hand, hold the cut end E of the string 1' with the fingers of the other hand,
This is let out through the guide hole 32' of the string guide 32 and wrapped around the object A to be bound in a ring shape. At this time, as shown in FIG. 5, the string is let out through the guide groove 9 provided in the string guide claw 8 and the cut groove 30 provided in the protective cover 29, and after being wrapped around the object A, the string is is the groove 30 and the guide groove 9 again.
After hanging it, the string end E is held by the string clamp 31. The preparation for the binding operation is thus completed. This string is easily fed out and the end of the string is securely set on the body, so the following operations are smooth.

Now, binding is accomplished as follows by manually pulling the drive handle 28 toward you (in the direction of the arrow) as shown in FIG. First, in Figures 1 to 3, when the pull shaft 22 of the handle is pulled in the direction of the arrow in Figure 13, the collar 23 at the tip of the shaft compresses the spring 24, and the shaft is initially connected. Rod 20
It only moves within the passage hole 25 provided in the
When the spring 24 is sufficiently compressed, the connecting rod 20
Since the rod is pulled, the rack 19 fixed to the rod is moved, and the pinion 18 that meshes with the rack and the bevel gear 17 integrated therewith rotate, and the bevel gear 1
The rotation is transmitted to the gear 7 that meshes with the gear 7, and the rear body 5'' of the cylinder 5 to which the gear 7 is attached and the front body 5' that integrally engages with this rotate together.In other words, the cylinder 5 as a whole rotates. Thus, when the cylinder 5 itself rotates, the string guide claw 8 at the end thereof and the disk 13 equipped with the engagement roller 15 for engaging with the cam ridge 6' of the cylindrical cam 6 rotate at the same time. As shown in FIGS. 5 to 8, by the rotation of the string guide pawl 8, the unwinding source and the tip of the string 1' passed through the guide groove 9 on the pawl 8 are kept aligned. Start rotating and use the bella hook 1
Slightly before the cylindrical cam passes through the base of the cylindrical cam (Fig. 7), wraps around the tip of the cylinder 5, and makes almost one full rotation (Fig. 8), the cam crest of the cylindrical cam becomes higher, and the cylinder 5 makes one revolution. Since the cam peak reaches its maximum at this point, the disk 13 attached to the front body 5' is gradually pushed up during this time, and the front body 5' itself moves away from the rear body 5'' against the force of the spring 16 and moves forward (first stage). In this way, the position of the string guide claw 8 also advances forward, and the position of the string in the guide groove 9 also moves forward, and the string is hooked onto the concave curved portion 11 of the hook 10 (the position of the string guide claw 8 moves forward). As the rotation progresses further, the cord is wrapped around the neck of the hook as shown in Figure 10.At this point,
As the drive handle 28 is pulled further forward,
The passage hole 26 provided in the connecting rod 20 strokes over the rear end of the hook rod 10' and retreats (toward the right in FIG. 2).
Engaging with the collar 27 attached to the rear end of the hook rod,
Since this is moved backward, the hook rod itself has a spring 33.
The hook 10 is retracted against the force, and the hook 10 is drawn into the cylindrical front body 5'. At this time, the bellows 12 is pushed forward by the inner surface of the front body 5' of the cylinder (Fig. 11), and the string that has been wound from the rear of the bellows to the concave portion 11 to form an annular shape is pushed back by the hook. Accordingly, the predecessor 5'
The end of the cord is left in front of the front body 5', while the end of the cord is passed through the cord ring and drawn into the body of the front body 5' while being held by the hook, and the binding is completed as shown in FIG. 12.
Note that while the string is gripped by the cut groove 9 of the string guide claw 8 and rotates around the hook, the string is cut by the cutting blade K as shown in FIG. The ends E and E' are now free and brought into the front part 5' by the bellows hook, where they are tied.

As mentioned above, the binding progresses by driving the handle 28, but the stopper 33 provided on the shaft 22
Once it reaches the guide 37 on the fuselage, it cannot be pulled any further and the operation is completed and stopped.

After the binding is completed as described above, when the tensile force applied to the drive handle 28 is weakened, the spring 38 attached between the end 39 of the rack 19 and the body 40 and the other springs 3
3, 34, etc. act, and the hook rod 10', the string guide pawl 8, etc. return to their original positions by the reverse restoring motion of the rack, pinion, bevel gear, gear 7, etc. that mesh with these, respectively.

At this time, the bellow hook 10 closed with the bellow 12
The rod advances from the front end opening of the front body 5' of the cylinder, the bellows opens as shown in Figure 1, and the hook itself is hooked in the state shown in Figures 10 and 11. However, in this case, the end of the string is pushed to come out, so the engagement between the loop at the end of the string and the hook is loose. Therefore, when the hook is lowered by manipulating the body by hand, the completed string comes out. The end can be removed from the hook and the job is complete.

In this way, the front and back ends of the tied threads are made into a loop, and the following thread is looped, pulled into the loop, and tightened, resulting in a single-bow knot made from one side of a bow. Therefore, it is convenient because the knot can be loosened by pulling the thread end.

As mentioned above, the binding machine of the present invention enables binding with a simple mechanism that uses only one cam, and the binding machine itself can be lightweight and compact, so it can be used in any location. However, it is extremely convenient and can be used for any type of object to be bound.
