Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a wire binding device. In more detail, when a long wire is made into a ring,
This is about a device for tying two parts together loosely so that they don't come undone.

(Prior Art) Various binding devices have been proposed for binding wire rods wound into a loop using binding material, but the purpose of these devices is to tightly tighten the bundled wire rods. Therefore, the wires to be bundled are tightened with a binding material such as plastics or string, and both ends of the binding material are tied together.These binding devices are used to bind wires with soft surfaces coated with nylon or vinyl chloride, etc. Then,
Items where the surface of the wire to be bound is likely to be scratched due to contact between the wires to be bound, contact between hard binding material and the wire to be bound, heating to tie both ends of the binding material, or metal fittings to fasten both ends of the binding cord, etc. It was hot.

On the other hand, wire rods with soft surfaces coated with nylon or vinyl chloride, etc., which are easily scratched, are bundled into a ring shape, for example, and any part of the circumference of the ring shape is formed into a ring shape without damaging the material. No device has yet been developed to tie the ring-shaped wire rods loosely enough to prevent them from unraveling, and until now, these tasks have been done by workers manually tying the ring-shaped wire rods with soft binding material such as mallet to avoid damaging them. It was exclusively about unity.

(Problems to be Solved by the Invention) Conventional binding devices for binding wire rods wound in a ring shape have the purpose of tightly binding wire rods wound in a ring shape, but In many cases, the strength with which the wires are tightened can be adjusted, and scratches caused by mutual contact between the wires to be bundled can be significantly prevented. However, in devices that bind with a binding material such as plastic, the surface of the wire to be bundled, which has a soft surface, is damaged, and both ends of the binding material are heated and fused. In addition, when binding with a cord-like binding string that is softer than the wire to be bundled, the ends of the binding string are crushed into an annular shape with a metal binding material such as aluminum. The binding material damages the surface of the wire to be bundled, which has a soft surface. Furthermore, in any conventional binding device, both ends of the binding material are tied, so when the binding is released, it is necessary to cut the binding material with a tool such as a knife, scissors, or pliers. There is a problem in that the wire material to be bundled is easily damaged by the tool.

The present invention has been made in view of the above-mentioned problems of the conventional technology, and its purpose is to provide an operating wire rope coated with nylon or vinyl chloride as specified in JIS G 3540. Or, in a similar device for tying wire rods, in order to prevent scratches caused by the tying material and contact scratches between the tying materials, the tying tightening strength is set so that the tying material is loosely tied to the extent that the tying material can maintain its ring shape, and both ends of the tying material are In order to prevent thermal scratches due to heating during tying or scratches caused by metal fittings used to tie both ends of the tying material, both ends of the tying material may be unfastened and left in a free state so that the wire to be bound remains in a loop shape. The aim is to provide a binding device that can.

(Means for Solving the Problem) In order to achieve the above object, the binding device according to the present invention uses upper and lower holes provided in a C-shaped rotating ring as guides, and uses coated wire material such as vinyl chloride. As shown in Figures 7 and 8, the material is wound two or three times in a spiral shape around the cross section of the ring-shaped bundle of wires to be bundled, and the tightening strength of the bundle is made loose enough to maintain the ring shape. One end of the tying material was pressed by a push rod, but the other end was left free. In addition, in order to prevent scratches when untying, both ends of the binding material were not fastened so that the binding could be released without using tools, but the binding holding power of the binding material was This is achieved by the rigidity of the core of the binding material itself, which is made of a coated wire material such as vinyl chloride, which is wrapped two or three times around the wire, so the annular part of the binding material that is spirally wound two or three times can be unraveled. It is possible to maintain an annular shape as shown in FIG. 8 without any distortion.

(Function) One end of the binder W fed by a predetermined length from the binder feed mechanism passes through the binder through hole 48, the space 64, and the upper and lower holes 62, and projects upwardly from the upper and lower holes, and the binder The other end is pressed and held against the inner surface of the binder passage hole 48 by a push rod 46 of the tie presser mechanism. The binding material W is sent out to a certain length and held at one end,
Subsequently, the cutting cylinder 34 operates, and the cutting cutter 4
0, the quill 12 is cut to a certain length at the exit of the binder at the tip.

Almost at the same time as the cutting is completed, the cutting cutter retreats, and the rotary drive body 38 closes the binding hole 48 and the upper and lower holes 6.
A fixed length of binding material W passing vertically through 2 is moved while being held by a push rod 46 by the operation of a holding cylinder 44, and is wound around the drum 66 approximately at the center of a C-shaped rotary ring 58 at the tip. The movement is stopped when it coincides with the approximate center of the cross section of the wire S, and the rotating wheel 5
8 starts rotating within the grooved cylindrical hole 60. Here, the lower end portion of the binding material W cut to a certain length is continuously held by the push rod 46, and the binding material from the holding portion to the upper end portion is in a free state, so that the rotating wheel 58 As the wire rotates around the wire S in the groove 68, the rotating ring pulls the upwardly protruding binder W through the upper and lower holes 62 into the space 64, and the free binder W rotates around the wire S. As a result, in the space 64, the wire rod S is wound around the wire rod S two to three times in a spiral shape with the binding material W to be bound.

When the above-mentioned binding is completed, the rotary wheel 58 starts to rotate in the opposite direction, and the rotary wheel 58 is positioned and stopped at a position where the upper and lower holes 62 are coaxial with the binding material through hole 48. Further, when the above steps are completed, the presser cylinder 44 is activated and the presser rod 4
6, and open the lower end holding the binding material W, which binds the wire S by the above operation, in the binding material passage hole 48. Subsequently, the rotary drive body 38 returns to the original state where the bundling operation was started, and the next bundling operation can be continued.

(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, 10 are rotated in opposite directions and pressed against each other by a force transmitted from a driving source (not shown).
A binding material W (for example, a vinyl wire coated with vinyl on iron wire) for binding the wire S bundled in a ring shape to be tied is held in between, and the quill is forcibly passed through the center of the quill 12 by the force of rotation in opposite directions. send it forward. The guide 14 guides the binder W to the feed rollers 10, 10. A binder transport mechanism is installed in front of the binder feed mechanism. A rear frame 20 and a front frame 22 are superimposed on each other next to a leg stand 18 fixed to the main body 16, and the cylinder body 26 is slid onto a guide rod 24 that is horizontally suspended parallel to the front frame 22. The cylinder body 26 is movably installed, and an L-shaped base plate 28 is fixed to the side of the cylinder body 26. This base plate 28 has a push plate 30 fixed to its rear end, and the front end of a cylinder shaft of a cutting cylinder 34 fixed to a rear plate 32 bent in an L shape at the rear end of the rear frame frame 20 and capable of moving back and forth. 36 is installed so as to be 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 bed plate 28, and below this rotary drive body 38, the rotary drive body 38 is located on the same plane as the tip of the quill 12 and at the outlet of the binder of the quill 12. A cutting cutter 40 is fixedly attached so that the cutting teeth are located right next to it, and when the cutting cylinder 34 is operated, the cylinder shaft tip 36 pushes the pusher plate 30 to release the binder at the tip of the quill 12. The cutting cutter 40 is designed to cut across. Further, a binding holding mechanism is installed above the cutting cutter 40 in an oblique direction that intersects with the rotary drive body 38. This binder pressing mechanism is the rotary drive body 3.
A presser cylinder 44 is fixed on a mounting plate 42 that is fixed diagonally by a base plate 28 below the presser cylinder 44, and a push rod 46 is fixed to the tip of the cylinder shaft that moves back and forth of this presser cylinder 44. It slides in a sliding hole provided in the base plate 28, and can 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 of FIG. 3. Here, rotation transmitted from a drive source (for example, a binding motor (not shown)) (rotation in the direction of binding the binding materials W by a rotation operation pin (not shown) (referred to as forward rotation)) and rotation in the opposite direction (referred to as forward rotation) A drive gear 5 with the same number of teeth is arranged in parallel on both sides of the rotary drive body 38 via a gear 50 and a one-way gear 54 with a ratchet mechanism 52.
6, 56, and the rotating wheel 58. This rotary ring 58 has a C-shape with teeth that mesh with the driving gears 56, 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 at, two or one of the two gears of the drive gears 56, 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 58
is provided with a vertical hole 62 that penetrates in the vertical direction and through which the binder passes, and furthermore, a binder through hole 48 is provided below in the base plate 28, directly above the binder outlet and through which the binder passes, A space 64 is subsequently provided above it. 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 tying motor is positioned, it rotates idly by a clutch (not shown), when the rotary drive body 38 is in the most retracted position (when the cylinder body 26 is located at the right end as shown in FIG. 2). ) A binder through hole 48 is provided directly above the binder outlet of the quill 12.
and the upper and lower holes 62 are positioned. Furthermore, at this time, the C-shaped gap of the rotary wheel 58 is positioned and installed in the front. In addition, this rotary drive body 38
When the cylinder body 26 moves forward (to the left in FIG. 2) and is at the most advanced position, the wire S passed vertically through the approximate center of the rotating ring 58 and wound around the drum 66 by the winding mechanism is located. It is set as follows. At this time, the groove portion 68 provided in the drum 66 is positioned in front of the rotary drive body 38 so as not to become a hindrance during the binding operation 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, by rotation of the feed rollers 10, 10, the binder W passes through the guide 14 and the quill 12 and is sent out by a predetermined distance above 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
It is also assumed that the vehicle is in the retracted position. Also, the rotary drive body 3
8 is 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 this binder feeding mechanism is passed through the binder through hole 48,
It passes through the space 64 and 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 push rod 46 through the sliding hole toward the binder through hole 48, and the binder W passes through the binder through hole 48. The tip of the binder W 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 26 that fixes the base plate 28 is attached to the guide rod 24.
As a result, the rotary drive body 38 fixed to the base plate 28 and the cutting cutter 40 fixed under the rotary drive body 38 are moved. 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, this cutting cutter 4
At approximately the same time as the end of the movement of 0, the cylinder body 26, which has been forcibly moved along the guide rod 24 as described above, begins to operate and moves along the guide rod 24 to the left in FIG. Therefore, the cylinder body 26
The rotary drive body 38 attached to the base plate 28 through the base plate 28 moves while holding a fixed length of binding material W passing vertically through the binding material passage hole 48 and the upper and lower holes 62 with a push rod 46.
The movement is stopped when the approximate center of the rotary ring 58 at the tip coincides with the wire S wound around the drum 66. (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.) Also, 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 rotary drive body 3
By operating the rotation operation pin 8, the binding motor is rotated in the forward direction, and the gear 50 and the ratchet mechanism 5 are rotated in the forward direction.
Power is transmitted through the two-way unidirectional gear 54 and drive gears 56, 56, and the rotating wheel 58 is connected to the grooved cylindrical hole 60.
Start rotating within. Here, the binding material W cut to a certain length is held and fixed by a push rod 46 at its lower end which is inserted into the binding material passage hole 48, and a space 64 above the held and fixed portion is inserted into the upper and lower holes. 6
Since the part of the binding material W that passes through the inside of the wire rod 2 and projects above the upper and lower holes 62 is in a free state, as the rotating ring 58 rotates around the wire S in the groove part 68, it moves upward from the rotating ring. While the protruding binding material W is drawn into the space 64 through the upper and lower holes 62, the free binding material W is rotated around the wire S, and as a result, the binding material W is tied around the wire S in the space 64. I will do it. When the above-mentioned bundling is completed, the rotary wheel 58 starts to rotate in the opposite direction by the rotary operation pin, and the ratchet mechanism 52 closes the upper and lower holes 62.
Rotating ring 58 at a position where it is coaxial with the binding material through hole 48
Position and stop. This position is the above-mentioned normal position where the C-shaped gap is located at the front. Further, once 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. Release one part of yourself. Subsequently, the cylinder body 26 moves along the guide rod 24 to the second position.
It starts moving to the right in the figure and returns to the initial state shown in FIG. 2, and then the binding motor is stopped. At this time, since the binder W binds the wire S, the end of the binder released as described above can leave the binder through hole 48 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, 10. Incidentally, the timing of 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 rotating ring that rotates around the wire rod is used to spirally attach the binding material to the wire rod using the upper and lower holes provided in the rotating ring as guides.
The wire is wrapped around three times, with one end of the wire being held by a push rod while the other end is being wound in a free state, so the tightening strength is loose enough to maintain the loop shape of the wire bundle. The wire will not be tightly tightened with the binding material. In addition, the binding holding power of the binding material is obtained from the rigidity of the core bar itself of the binding material, which is made of coated wire material such as vinyl chloride, which is wrapped around the wire two or three times in a spiral shape, so both ends of the binding material are There is no need to fasten it, and it is in a free state as shown in FIGS. 7 and 8. Therefore, the wire rods will not be damaged by the binding material, and the wire rods will not be damaged by contact with each other, and there is no need to cut the binding material with a tool, and the binding can be released by gently pulling it apart with your fingers. This eliminates the possibility of scratches caused by tools. 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 will be more effective.
