Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a wire binding device. More specifically, it is a device for loosely tying a long wire into a loop at one or two places around the loop to prevent it from unraveling.

(Prior Art) Various binding devices have been proposed for bundling wire rods and tightening them using a binding material, but all of them are for firmly tightening the bundled wire rods. On the other hand, for example, a soft wire material that is easily damaged is bundled into a ring shape, and one or two places around the ring shape are tied loosely to the extent that the material is not scratched and the wire material is not unraveled. Machines have not yet been developed, and until now this work has been carried out exclusively by workers manually tying the ring-shaped wire with soft binding material such as mallet to prevent damage.

(Problems to be Solved by the Invention) Conventional binding devices that can bundle wire rods and tie them with knots are designed to tightly bundle the materials, and for this purpose, the wire rods are tightly attached to each other so that they do not move. tied up.

Therefore, since the wires inevitably come into contact with each other, the bundled wires may be damaged. Furthermore, the method of tying bundled wire rods using conventional binding devices is a simple method of covering the outer periphery of the wire with binding material and then twisting the ends of the binding material to secure them together. Work hardening occurred, and the bumps came into contact with the wire, making the material more susceptible to scratches.

Because of these factors, wire rods that have traditionally been bundled are limited to those that do not cause any problems even if they are slightly scratched, or are used only for wires that are hard enough to avoid scratches. 0 The present invention provides a device that can bundle materials that are prone to scratches, such as wire rods coated with paint such as nylon or vinyl, into a ring shape and loosely bundle them to prevent scratches. The purpose is to

(Examples) Examples of the present invention will be described below with reference to the drawings. FIG. 1 is a front view of the main parts of the present invention, FIG. 2 is a plan view thereof, and FIG. 5 is an overall external view. In FIG. 1, feed rollers 10 and 10 rotate in opposite directions and press each other due to the force transmitted from a drive source (not shown), and bind the wire S bundled in a ring shape to be tied. A binding material W (for example, a vinyl wire coated with a steel wire) is held between the quills 12 and 12, and is forcibly sent forward through the center of the quill 12 by the force of rotation in opposite directions. The guide 14 is a feed roller 10 for the binder W.
．． This is the guide up to 10. A leg stand 1 fixed to the main body 16 has a binding material transport mechanism installed in front of the binding material feeding mechanism.
A rear frame 20 and a front frame 22 are attached to the sides of the front frame 8 in an overlapping manner, and a cylinder body 26 is slidably installed on a guide rod 24 that is horizontally suspended parallel to the front frame 22. An L-shaped base plate 28 is fixed to the side of the body 26. This base plate 28 has a push plate 30 fixed to its rear end,
A cutting cylinder 34 fixedly installed on a rear plate 32 bent into an L shape at the rear end of the rear frame frame 20 is installed so that a cylinder shaft tip 36 movable back and forth is in contact with the push plate 30. Further, a rotary drive body 38, which will be described later, is fixed to the side of the base plate 28 so as to be parallel to the base plate 28, and below this rotary drive body 38, the rotary drive body 38 is in the same plane as the tip position of the quill 12 and the quill 12
A cutting cutter 40 is fixedly attached so that its cutting teeth are positioned immediately next to the binding material outlet of the quill 12. When the cutting cylinder 34 is operated, the cylinder shaft tip 36 pushes the push plate 30, thereby cutting the quill 12. The cutting cutter 40 is arranged to cross the tying material outlet at the tip. Further, above the cutting force cover 40, a tying material pressing mechanism is installed in an oblique direction intersecting the rotary drive body 38. In this binder holding mechanism, a presser cylinder 44 is fixed on a mounting plate 42 that is diagonally fixed by a base plate 28 under a rotational drive body 38.
A push rod 46 is fixed to the tip of the cylinder shaft that moves back and forth, and the push rod 46 slides in a sliding hole provided in the base plate 28.
It is allowed to move back and forth toward a binding material passage hole 48, which will be described later, which intersects with this sliding hole. FIG. 3 shows a structural diagram of the rotary drive body 38, and FIG. 4 shows a sectional view taken along line IV-IV in FIG. Here, the rotation transmitted from a drive source (for example, a binding motor (not shown)) (the binding material W is
The gear 50. can be rotated in the direction of binding (referred to as forward rotation) and in the opposite direction (referred to as reverse rotation). One-way gear 54 with ratchet mechanism 52
The signal is transmitted to drive gears 56 and 56° rotating wheels 58 having the same number of teeth and arranged in parallel on both sides of the rotary drive body 38. This rotary ring 58 has a C-shape with tooth profiles that mesh with the drive gears 56 and 56 around its periphery, and is rotatably inserted into a grooved cylindrical hole 60 provided at the tip of the main body of the rotary drive body 38. No matter which position the rotary wheel 58 is rotated in, two or one of the two gears of the drive gear 56 and 56 mesh with each other, so that the driving force from the drive source is always applied. It has a structure that rotates by transmission. This rotating wheel 5
8 is provided with a vertical hole 62 through which the binder passes in the vertical direction, and a binder through hole 48 through which the binder passes is provided in the base plate 28 in the vertical direction directly above the binder outlet. , a space 64 is provided below.

When the rotary wheel 58 is reversely rotated by the drive source of the rotary drive body 38, the rotation stop position of the rotary wheel 58 is determined by the ratchet mechanism 52 so that the upper and lower holes 62 are located coaxially with the binding material passage hole 48 ( After the binding motor is positioned, it rotates idly by a clutch (not shown), and when the rotary drive body 38 is at the most retreated position (when the cylinder body 26 is located at the right end as shown in FIG. 2). The binder passage hole 48 and the upper and lower holes 62 are positioned directly above the binder outlet of the quill 12. Furthermore, at this time, a C-shaped gap of the rotary wheel 58 is positioned and installed in the front. Further, this rotary drive body 38 is moved by the advancement of the cylinder body 26 (second
At the most advanced position (left side of the figure), the wire S wound around the drum 6G by the winding mechanism is positioned so as to pass through the approximate center of the rotary ring 58 in the vertical direction. At this time, the groove 68 provided in the drum 66 is positioned in front of the rotary drive body 38 so as not to interfere with the binding work of the rotary drive body 38.

The operation of tying the wire S wound around the drum 66 using the tying material W in the embodiment apparatus having the above structure will be described. First, the binding material W is guided by the rotation of the feed roller 10.10. It passes through the quill 12 and is sent upward by a predetermined length from the binder outlet. At this time, the cylinder body 26
is located at the right end, and the cylinder shaft tip 36 of the cutting cylinder 34 is also in the retracted position. Also, the rotary drive body 3
8 is also assumed to be located at a fixed position by the ratchet mechanism 52 (the C-shaped gap is located at the front, and the upper and lower holes 62 are located coaxially with the binding material passage hole 48).

Therefore, the binder W fed out for a certain length from the binder feeding mechanism is inserted into the binder through hole 48. Space 64. It passes through the upper and lower holes 62 and projects above the rotary drive body 38 . Next, the presser cylinder 44 fixed on the mounting plate 42 is operated to advance the pusher rod 46 through the sliding hole toward the binder through hole 48 .
The tip of the binder W passing through the hole is pressed against the wall of the binder passage hole to hold and fix the binder W. Subsequently, the cutting cylinder 34 is operated, and the cylinder shaft tip 36 presses the push plate 30 installed on the rear end of the base plate 28, and the cylinder body 2 fixes the base plate 28.
6 is moved along the guide rod 24, thereby rotating the rotary drive body 3 together with the rotary drive body 38 fixed to the base plate 28.
The cutting cutter 40 fixed under the cutter 8 moves. As a result, the cutting cutter 40 traverses the binder outlet at the tip of the quill 12, and cuts the binder W sent out for a certain length with its cutting teeth. Almost simultaneously with the start of movement of the cutting cutter 40, the binding motor, which is the drive source of the rotary drive body 38, starts rotating. Also, at approximately the same time as the movement of the cutting cutter 40 ends, the cylinder body 26, which was forcibly moved along the guide bar 24 as described above, starts operating and moves along the guide bar 24 to the left in FIG. do. Therefore, the rotary drive body 38 attached to the cylinder body 26 via the base plate 28 is connected to the binding material through hole 48.
A fixed length of binding material W passing through the upper and lower holes 62 vertically is moved while being held by the push rod 46, and when the approximately center of the rotary ring 58 at the tip is aligned with the wire material S wound around the drum 66, the movement is stopped. Stop.

(At this time, the bevel of the C-shaped rotary wheel 58 is directed toward the tip of the rotary drive body 38, so it does not interfere with movement.) When the movement of the cylinder body 26 stops, the cylinder axis of the cutting cylinder 34 The tip portion 36 is pulled back to its original position and is ready for the next cutting operation of the binding material W.

Then, following the completion of the movement of the rotary drive body 38, the rotation of the binding motor is caused to rotate in the forward direction by operating the rotation control pin of the rotary drive body 38, and the gear 50. One-way gear 54 with ratchet mechanism 52. Power is transmitted through the drive gears 56,56 and the rotating wheel 58 begins to rotate within the slotted cylindrical hole 60.

Here, the lower end of the binding material W cut to a certain length is inserted into the binding material through hole 48 and is held and fixed by a push rod 46, and a space 64. Since the binding material W in the portion that is inserted into the upper and lower holes 62 and further protrudes above the upper and lower holes 62 is in a free state, the rotating wheel 58
As it rotates around the wire S in the groove 68,
The binder W protruding upward from the rotating wheel is drawn into the space 64 through the upper and lower holes 62 while the binder W is in a free state.
is rotated around the wire S, and as a result, the wire S is bound around the wire S with the binding material W in the space 64. When the above-mentioned binding is completed, the rotary wheel 58 starts to rotate in the opposite direction by the rotary operation pin, and the rotary wheel 58 is positioned and stopped by the ratchet mechanism 52 at a position where the upper and lower holes 62 are coaxial with the binding material passage hole 48. This position is the above-described regular position where the C-shaped gap is located in the front. Further, when the position is reached, the force from the drive source is cut off via a clutch (not shown).

Furthermore, when the above is completed, the presser cylinder 44 fixed on the mounting plate 42 pulls the push rod 46 through the sliding hole, and holds and fixes the binder W, which has bound the wire rod S by the above operation, in the binder through hole 48. Let go of what you are doing. Subsequently, the cylinder body 26 starts moving rightward in FIG. 2 along the guide rod 24 and returns to the initial state shown in FIG. 2, and then the binding motor is stopped. At this time, since the binding material W is in a state where the wire rod S is bound, the binding material end released as described above is in the binding material through hole 4.
8, it is possible to leave without any resistance. This state is the state in which the original binding work is started, and if the binding work is to be continued, it is possible to continue the binding work by feeding out the binding material W by a fixed length by rotating the feed rollers 10 and 10. Incidentally, the timing of the cylinder operation for each of the above operations can be easily determined using, for example, a limit switch, and a timing diagram of the operation is shown in FIG.

(Effects of the Invention) As can be seen from the above explanation, in the present invention, a knot is wound around the wire using a rotating ring that rotates around the wire, using upper and lower holes provided in the rotating ring as guides, and one of the ties is wrapped around the wire. Since the ends of the wire are in a free state, the tightening is loose, and the wire rod is not tightly tightened with the binding material. Therefore, the wire rods are not scratched by the binding material, and the wire rods are no longer scratched by contact with each other. Furthermore, since this binding device has a simple structure and is easy to install, it can be used in parallel with various wire winding devices, and when used in this way, it is even more effective.
