DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wire winding device,
It is an automatic device that continuously performs the work of winding electric wires, thin tubes, and other long wire rods onto a replenishing reel.

[0002]

2. Description of the Related Art A number of inventions and ideas have already been announced for this type of wire winding apparatus, including Japanese Patent Publication No. 53-24585 "Linear winding machine" shown in FIG. In either case, when one of the pair of left and right reel drive units that make the axis parallel and reverse the winding rotation direction is fully wound, the axis is set horizontally behind the wheel with pawls that support the reel and wait. The short cylindrical cover is moved forward to cover the vicinity of the car-side winding cylinder with the claw, the middle of the feeding wire is hooked on the claw of the car with the other claw, the wire is cut, and the cut end is taken into the cover. It is intended to be included. Needless to say, the winding wire is continuously wound by the pair of left and right winding frame driving units alternately without a break, so that the feeding wire is wound from the full winding frame 1 (the winding frame which has been wound up to a required length) to the empty winding frame 1 '. Ingenuity has been devised at each location. However, the point that does not change is that the wire rod facing the full winding frame 1 is pushed and hooked on the wire capturing claw 3 'of the wheel 2' with the claw 2 on the empty winding frame side, and the wire is cut. The cover 6 covers the pawl 3 of the wheel 2 with the pawl that rotates the winding frame 1 so that the pawl 3 is not caught.
In that the wire end of the full bobbin 1 is confined inside to prevent it from being swung outside until the bobbin stops, and that the outer wire of the full bobbin is not hit and damaged by the wire bobbin 4 And so on.

[0003]

In this type of winding device, the most important wire material is transferred from a full winding frame to an empty winding frame, and in particular, a wire terminal which is swung until the full winding frame stops is confined in a cover. What is decisive for the mechanism is undeveloped. At present, the bouncing wire ends are forcibly pushed between the cover of the car with claws and the full winding material cover. A first object of the present invention is to develop a new method for guiding a wire terminal into a cover more straightforwardly. Conventionally, a thin wire is cut by excessive tension between the full winding frame and the empty winding frame, and a thick wire is cut by pressing the middle of the wire against an upward cutting edge by the movement of the claw on the empty winding frame side. The portion close to the terminal becomes thinner and brittle than the specified size due to excessive tension, and the cut portion is also undefined. In the latter case, the terminal is left unusually cut off.
It is an object of the present invention to improve this. Also, the present invention provides an empty winding frame that affects the productivity of this type of winding device,
Streamline the unloading mechanism for full frames.

[0004]

According to the wire winding device of the present invention, when one of a pair of left and right winding frame driving portions for making the axis parallel and reversing the winding rotation direction is fully wound, the winding is carried out. Behind the claw-supporting frame, the short cylindrical cover with its axis set to the horizontal position is advanced to cover the vicinity of the claw-equipped winding cylinder, and the other side of the claw of the claw-equipped wheel is covered with the feeding wire. In the wire winding device that cuts the wire rod and takes the cutting end into the inside of the cover, the cover is an annular body having an inward U-shaped groove, and the groove width of the annular body is set to the cover. It is constant except for the vicinity of the wire introduction port, and the vicinity of the wire introduction port is in the lower half of the ring body near the adjacent winding frame, and the upward wire introduction port protruding forward from the front of the constant width portion of the ring body Before cutting the feed wire, advance from the standby position and press against the front edge of the wire introduction port When the wire rod is transferred from the full bobbin frame to the empty bobbin frame by these, when the wire rod is transferred from the full bobbin frame to the empty bobbin frame, the cut wire bobbin terminal goes down along the front surface of the cover and goes down as it is. U of cover from inlet
It is characterized in that it is drawn into the groove.

In order to improve the wire cutting means, in the above-described apparatus, when the middle of the feed wire is hooked on the claw of the wheel with the other claw, the rotation of the wheel with the claw causes the wire to be lowered by tension. In some cases, a pair of facing wire cutting rotary blades are provided at a passing position on the way.

[0006] In the wire winding device of the present invention, in which the supply and unloading of the winding frame are improved, when one of the pair of left and right winding frame driving units for making the axis parallel and reversing the winding rotation direction is fully wound. In the rear of the car with the pawl supporting the reel, the short cylindrical cover with the axis lined horizontally is moved forward to cover the vicinity of the winding cylinder near the car with the pawl, and the middle of the feeding wire with the pawl on the other side. In a wire winding device that hangs on a nail of a car, cuts a wire, and takes a cutting terminal into the inside of the cover, a horizontal rail that can move up and down under a common base of the pair of winding frame driving units. A bogie for the bobbin that moves between the bobbin delivery position at the rail end and the bobbin mounting position of the two drive units, and ascends and descends. Having a pair of parallel bars that can lift and lower the reels And it features.

[0007]

In this kind of winding device, the middle of the wire running toward the full winding frame is pushed farther rearward than the outer edge of the cover by the line pulling lever, and the wire is hooked on the claw of the wheel with the claw of the empty winding frame. Since the cutting terminal is cut in that state, the cutting terminal is swung with the full winding frame while bouncing around the outer edge of the cover. Conventionally, the end of the wire rod is further pressed inwardly from the outer edge of the cover with a restraining ring or the like, so that the end of the wire hits the upper layer of the fully wound material due to the reaction, and a cover for preventing this is required. On the other hand, according to the present invention, the cover is formed as an annular body having an inward U-shaped groove, and an upward wire introduction port is provided so as to protrude forward. As a result, the wire end that is drawn in by the full frame, advances along the front surface of the cover, and is cut down as it is, is drawn down from the introduction port into the inside of the U-shaped groove of the cover.

In order to securely insert the wire end into the inlet, the present invention adds a wire guide plate which advances from a standby position and is pressed against the front edge of the inlet before cutting the wire. The rebounding part of the tail end of the wire rod which descends along the front surface of the cover and enters the introduction port also loses energy by hitting the guide plate, and goes straight into the cover. The wire end that is spirally bent from the inlet and placed in the constant width U-shaped groove of the cover turns there until the full winding frame stops. The wire cutting device according to the present invention is a pair of wire cutting rotary blades facing each other, the position of which is a wire caught by a claw of a claw-equipped wheel on the side of an empty winding frame, which increases tension between the wire and the full winding frame. Since it is at the passing position where it can be lowered, when the wire rod passes through between the rotary blades,
It is divided instantaneously by the clamping force of both rotating blades or the tension caused by the shearing force and the tension. Unlike conventional stationary blades, it is a beautiful cut because it is sandwiched between rotating blades.

[0009] The reel feeding and unloading mechanism of the winding device according to the present invention is a reel bogie for stably mounting an empty reel or a full reel.
On the ascending and descending horizontal rails below the common base of both reel drive units, the reels are moved at any time between the winding devices and the reel delivery position. The bogie has a pair of parallel bars, and when the loaded reel is moved out, the bars on any side can be raised. And since these are mounted on a horizontal turntable, when kicking out the full winding frame wound by the left and right winding frame drive units and turning it, turn the turntable so that the wire end does not rewind due to the rotation. Can be turned.

The groove width is constant except for the vicinity of the wire introduction port 11. The wire introduction port 11 is an upward opening protruding forward from the front of the constant width portion of the ring body, and the wire W entered therefrom is drawn into the constant width portion along the introduction portion below. Accordingly, the wire introduction port 11 of the covers 10 and 10 'and the vicinity of the introduction section below the wire introduction port 11 are respectively provided in the lower half near the adjacent winding frame. Although the rotary blade 13 for cutting the wire rod when the left bobbin 1 is fully wound is omitted in FIG. 1, it is on the right side of FIG. . In other words, the rotary blade 13 or 13 'is located at a position close to the claw 3 or 3' which goes down by tensioning the wire W in the middle.
This is a design matter. FIG. 3 shows where the rotary blade 13 cuts the wire W. FIG.
The guide plate 12 which has been waiting on the reciprocating drive rodless cylinder 14 of FIG. 1 is advanced by the cylinder until it comes into contact with the front edge of the wire introduction port 11 and then stopped.
2 shows a state in which a line shift lever 16 (corresponding to the line shift lever 9 in FIG. 10) is protruded by the fluid pressure cylinder 15 attached to the second cylinder 2.

FIG. 3 shows a state immediately before the wire W is cut.
The wire W between the wire pulling lever 16 and the full winding frame 1 runs along the front surface of a portion having a constant groove width above the wire introduction port 11 of the cover 10 as shown in FIG. Therefore, the nail 3 'in FIG.
As a result, the wire W is pushed down, and as shown in FIG.
When the wire end is pushed into the space between the claws 3 and 13, the wire end on the side held by the claw 3 ′ in FIG. Before being swung, the wire cut end is drawn obliquely downward through the front end of the wire drawing lever 16 and the front surface of the constant width groove of the cover 10, and is drawn into the wire inlet 11 immediately below. Before being pulled in, it bounces once, hits the guide plate 12 and enters the inlet 11 gently, is guided spirally from the place where the groove width is wide to the place of constant width, and is swung until it stops there. A pair of rotary blades 1
The 3'13 rotates and cuts when the wire is pushed between the opposing blades. In this embodiment, the shape of the frusto-conical blade is slightly engaged with the blade for shearing.

Next, the apparatus of the embodiment shown in FIGS. A pair of left and right reel drive units A and B, a common base 17 for them, a horizontal rail 18 that can be raised and lowered thereunder, a reel delivery position 18a at the end thereof, a rail 18 on which the reel 1 is mounted.
The bobbin bogie that moves up and moves up and down with the rail 18
9, the left and right elevating guide columns at both ends of the rail 18 are 20; the elevating motor for synchronously driving the elevating mechanism in the column is 21 (FIG. 5); R denotes a wire guide roller of the traverser, which largely moves to the right or left when rewinding by full winding. The reel drive units A and B drive the pawl wheels 2 and 2 ′ by the respective motors 23 and 23 ′. The pawl wheels 2 and 2 ′ are rotatably driven by sandwiching and supporting the winding frame located at the winding frame mounting position between the opposed pressing plates 2 a and 2 a ′. The covers 10 and 10 'of this embodiment are shaped as shown in FIGS. 6 and 7, and the wire introduction ports 11 and 11' unique to the present invention protrude forward and outward from the fixed width groove portion of the cover. If it protrudes outward, it is easier to receive the cut wire end than the one only on the front side as shown in FIG.

Although the bogie carriage 19 mounts the flange of the bobbin 1 on a pair of parallel bars 19a as in the prior art, the parallel bar 1
9a can be lifted and lowered independently, so that the reel 1 can be transferred to either side. Since they are placed on the horizontal turntable 24, the left and right full reels whose winding directions are reversed are: The wire can be transferred so that it does not unwind. Both ends of the parallel bar 19a of this embodiment are supported by links 25 crossing each other, and each link 25 is supported at its lower end by a bearing 24a that hangs down from the turntable 24. At the winding frame delivery position 18a, there is a pulling drive mechanism (not shown). By pulling up one link 25 as shown in FIG. 9, the parallel bar 19a attached thereto is pulled up and the winding frame 1 is moved out. Although an embodiment has been described above, it goes without saying that the present invention can be variously changed and applied depending on the implementation conditions without changing the gist.

[0015]

According to this kind of winding device in which the winding frames are arranged right and left and the wire material is wound alternately and continuously, the wire material terminal is forcibly prevented from bouncing around at the time of rewinding and cutting. The company has removed the conventional wisdom of pushing it in and has opened a new system that allows you to go straight into the cover without pushing it.
In other words, the cover is a grooved ring that opens in the centripetal direction, and a part of the groove width is widened to the front side to form an upward wire introduction port. Even if the wire that was facing the middle was cut off and jumped forward, the wire end lost its momentum by hitting the guide plate hitting the inlet, dropped calmly down to the inlet just below, and in the constant width groove of the cover Swung until stopped. Therefore, the means for pushing the wire end into the cover and the cover for protecting the wire material on the outer periphery of the full winding frame and the drive means for them are not required, which is simplified. Further, in the present invention, a pair of rotary blades that rotate and cut when the wire is pushed in is used for cutting the wire at the time of rewinding, and the wound wire has a regular size up to the end. Further, the reel feeding and unloading mechanism of the present invention is not only automated, but also a rotating platform is added to a reel bogie, and the left and right full reels are rolled out in a direction in which the winding does not return, and the conventional gripper is used. Eliminates lifting equipment.
