Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to an automatic wire winding device, which changes the winding frame one after another and winds a fixed amount of wire using a traverser.

<Prior art> The most important part of an automatic winding device for winding comparatively thin wires such as electric wires in fixed quantities is a mechanism that switches the wire to the next winding frame when a fixed quantity has been wound onto the winding frame. It is.

Such a switching mechanism is known from Japanese Patent Laid-Open No. 18863/1983. In this method, a rail is installed between the bobbin (winding frame) and a wire feeding traverser, almost perpendicular to the wire, and after the bobbin has wound a certain amount of wire, a terminal processing device is run along the rail, and the wire is fully loaded. The filament between the winding bobbin and the traverser is held in its mouth, cut, and the cut end is passed to the filament gripping part of the bobbin holding rotating part.

<Problems to be Solved by the Invention> In the above-mentioned conventional technology, the device that has completed the terminal processing between the bobbin and the traverser must be returned to the outside standby position. Therefore, a troublesome process is required in which the winding operation of the bobbin is once started and then stopped, and the stretched filament is pushed up by the processing mechanism and returned to the standby position by passing through it.

The present invention provides an automatic wire winding device having a wire switching mechanism that does not have the above drawbacks.

<Means for Solving the Problems> The automatic wire winding device of the present invention is a device that changes the winding frame one after another and winds up the wire in fixed quantities, and has the following features: , Attached to the wire guide traverser, the part of the subsequent wire heading toward the fully wound reel is protruded into each opening between the wire cutter and the movable clamp arranged upstream of the wire cutter on the same traverser. It is attached to the traverser with a filament ejecting device that inserts the filament, and the movable clamp attached to the tip thereof, which clamps the filament before cutting with the cutter, and moves after cutting to remove the cut end of the filament. An actuating arm that passes over and returns to the wire clip, and is characterized by comprising the following.

<Function> The automatic wire winding device of the present invention includes a wire guide traverser, a wire cutter, an operating arm with a movable clamp,
and a filament ejection device was installed. Therefore, these are located together with the wire outlet of the traverser, which always moves left and right, and when the reel is fully wound, no matter where the traverser is and stops, the ejector immediately moves the wire toward the reel. It can be inserted into each opening of the cutter and clamp.
After the filament is clamped and cut, the traverser is moved to the winding start end of the left and right strokes. Then, the operating arm moves the movable clamp that holds the cut end of the filament in its mouth, and returns the cut end to the filament clamp of the winding frame holding rotating section. If the fully wound reel is replaced with a new reel during this time, the winding operation can be resumed immediately.

<Embodiment> Figures 1 and 2 show an entire embodiment of this invention, which is an almost fully automated example. The winding frame 1 on the inclined plate 6 shown in FIG. 2 sequentially moves along the front surface of the machine body 10 and reaches the top of the moving table 11. It is placed on this moving table 11, turns around, and enters the gate-shaped frame which is the winding position. . As shown in Fig. 1, there is a reel holding head 1.
2 and 13 are facing each other.

When the moving table 11 comes to the normal position, the push-up cylinder 14 pushes the winding frame 1 up to the clamping position as shown in FIG. (Figure 4). clamping head 12,
The former of 13 is the rotation drive side, and the latter is the pressing side. In order to wind the filament W around the new winding frame 1 held between the two, it is necessary to fix its tip to the winding frame 1 and then rotate it.

In this invention, the tip of the filament W is not attached to the winding frame 1, but in this example, it is sandwiched between the filament clips 15 which are clamped by spring pressure. The filament clip 15 is attached to the end of a support arm 15a extending outward from the clipping head 12, which is a rotating portion for clamping the winding frame. As shown in FIGS. 4 and 5, the filament clip 15 of this embodiment has a built-in coil spring 16, and constantly pulls the head to pinch the filament W. When replacing the winding frame 1, the filament clip 15 is parked in front of the opening/closing actuator 17 provided on the machine body 10 side. Press. Then, the coil spring 16 is compressed and the head of the filament clip 15 protrudes, so that the previously gripped filament end is released. Just open the filament clip 15 and wait for a new filament end. It should be noted that a stopper for correctly stopping the filament clip 15 in front of the operating tool 17 is optional, but in this embodiment, a positioning hole material 18 is attached to the clamp head 12,
The rod tip of the fluid pressure cylinder 18a is inserted and parked in the correct position. In Figure 4, hole material 1
8 is one piece, and in Fig. 5 there are two pieces.

Now, when the winding frame 1 becomes full and is replaced with a new winding frame 1, in this invention, the wire end, which is the winding start end of the previous winding frame, is removed from the wire clip 15 as described above, and the wire is replaced with a new winding frame 1. Cutting the final end of the wire and leaving the cut wire end open for the next winding.
It is necessary to add it to 5. The mechanisms that perform the latter two operations are all attached to the traverser 3 in this invention.

Needless to say, the filament W sent from the filament supply source is wound up while being moved laterally by a well-known traverser 3 in order to wind it uniformly within the effective width of the winding frame 1.
Therefore, it is not determined at which position the traverser 3 will reach full winding (fixed amount winding).

According to this embodiment, the winding of the filament W is stopped immediately when the filament W is fully wound, and the groove wheel 19 of the filament ejecting device, which is waiting in front of the traverser 3, is moved from the solid line position in FIG. 3 to the chain line 19. ’ position. As shown in FIGS. 6 and 7, this groove wheel 19 is supported by a support arm 21 and a rail 23 so as to be positioned directly below a guide groove wheel 20 that moves the supply wire W left and right, and is supported by a hydraulic cylinder 22. It is projected from the standby position. When the cylinder 22 is actuated to project the groove wheel 19 straight forward, the groove wheel 19 moves forward in a plane including the line W between the guide groove wheel 20 and the winding frame 1.
Multiplying the middle of this will make it stand out. The state in which the filament W protrudes in the middle is shown as a chain line 19' in FIG. 3, and as a solid line 19 in FIG. Figures 7 and 8 show a plan view and an elevation view of the filament ejecting device. The support arm 21 of the groove wheel 19 is a rail 23
Because it moves along the same line, it performs accurate movements.

The cutter 24 and the movable clamp 25 are opened on the same plane as the filament W and are waiting.
The former is fixed to the tip of an arm 24a that protrudes forward from the traverser 3, and the latter is fixed to the tip of an operating arm 26 that swings with a fulcrum on the front surface of the traverser 3.
When the fluid cylinder 27 is actuated, the actuating arm 26 pivots downward about the pivot support 28.

As shown in FIGS. 3 and 6, the upper part of the filament W projected forward in a dogleg shape by the groove wheel 19 enters the cutter 24 and the movable clamp 25 on the upstream side, which are opened and waiting in line. . Therefore. First, clamp 25
grips the filament W by the built-in hydraulic cylinder (see Fig. 9), and then the cutter 24 operates the hydraulic cylinder 29 (Fig. 10) to protrude the blade 30.
The filament W that has entered the V-shaped groove 31a of the lower die 31 is sheared.

One of the cut ends of the filament is the winding end of the winding frame 1, and is carried out as is or temporarily fixed to the winding frame 1 by an arbitrary method. The other end held in the clamp 25 is clamped when the traverser 3 reaches the winding start end, that is, the stroke end on the side of the clamping head 12 and stops (Fig. 4), or just before that, the fluid pressure cylinder 27 is actuated and clamped. 25, and the end portion of the filament W is released and placed into the waiting filament clip 15. Then, when the actuating tool 17 (Fig. 5) that had been pushed out is pulled back so that the filament clip 15 pinches the end of the filament W, and the built-in cylinder of the clamp 25 is released, the force is released.
The delivery of the wire end is completed. Therefore, by returning the blade of the cutter 24, returning the operating arm 26 and the groove wheel 19 of the wire ejecting device to the standby position, and sandwiching a new reel 1 between the clamping heads 12 and 13, the winding can be resumed immediately.
Since the time required is short, if there is an accumulator equipment on the wire supply side, the work can be continued continuously.

Although one embodiment has been described above, this invention can be modified according to design conditions without changing the gist of the invention.
It goes without saying that it can be varied and applied in a variety of ways depending on the well-known techniques of mechanical engineers, such as the structure of the spring-pressure wire clip 15, the structure of the actuator that opens and closes it, the structure of the wire cutter 24, and the clamp 25. , the structure of the actuating arm 26, their driving force source, etc. will be designed differently depending on the machine designer.

<Effects of the Invention> The present invention conventionally includes a special provision of a wire end processing device that moves laterally between a winding bobbin and a traverser, and when the winding is full, the processing device is run from a standby position to a position where the traverser stops. After processing, the trouble of having to start and then stop the winding operation of the bobbin so that the device could slip under the filament and return was eliminated.

That is, in this invention, since the cutter, the actuating arm with a clamp, and the wire ejecting device are attached to the traverser, it is possible to immediately clamp and cut the trailing wire of the fully wound spool regardless of the stopping position of the traverser. Then, by returning the traverser to the winding start position and activating the actuating arm, the clamped filament cut end can be reliably passed to the filament clamps of the winding frame clamping rotating section and returned. If the winding frame is replaced during this time, winding can be restarted immediately, significantly increasing work efficiency compared to conventional methods. The downtime before winding resumes has been significantly shortened.
