Description

[Detailed description of the invention] (Industrial application field) The present invention is a winding device that is used to temporarily hold the winding wire wound around a bobbin or to cut the winding wire by moving it while being held. This invention relates to a wire pinching device for a wire machine.

(Prior art) In an automatic winding machine, a winding wire is wound around a terminal pin set on a coil bobbin, the winding wire is caught between wire clips, and the wire clips are rapidly moved.
Wire pinching devices for winding machines that can cut windings are known.

The inventor of the present invention also proposed a wire pinching device for a winding machine in Utility Application No. 58-204809.

(Problem that the invention aims to solve) In recent years, winding bobbins have become more complex, and the terminal pins are provided at multiple locations instead of one, and are placed at different positions in the spindle direction. There are more and more things.

On the other hand, in order to perform the sudden movement of the wire clipper required to cut the winding of an automatic winding machine, and the quick movement of the wire clipper with a relatively long stroke to retract the wire clipper during winding, a movable wire clipper is required. move forward in a straight line,
It is best to use a retracting type actuator, such as an air cylinder.

However, with this type of actuator, it is difficult to select a plurality of different positions for advancing and stopping.

Furthermore, in recent years, automatic wire winding machines have been equipped with a large number of spindles and a plurality of wires can be wound simultaneously, so there is a problem that the wire pinching device must also be able to handle this.

The purpose of this invention is to solve these problems and
It is an object of the present invention to provide a wire clipping device for a winding machine that can quickly move a plurality of wire clips in accordance with the positions of the terminal pins of a plurality of coil bobbins.

(Means for solving the problem) In order to achieve the above object, the wire clipping device for a winding machine according to the present invention will be summarized as follows in conjunction with embodiments.

Rods 4, 4, wire clamp support 5, positioning plate 9
The actuator 12 advances and retreats the assembly of the guide rods 4, 4, the wire clamp support 5, and the positioning plate by moving forward and backward the movable part attached to the positioning plate 9 and having a head 10a for spacing adjustment at the tip. an actuator 10 that selects the position where the assembly of the coil bobbin 16 held on the spindle 2 moves forward and stops; , 7b, the wire clipping 7 is holding the terminal 16a or 16b.
A movable part provided on the base 1 is composed of an actuator 11 that moves forward and backward, and can cut the winding by driving the X-movement table 3 so as to move away from the base 1.

(Example) The present invention will be described in detail below with reference to the drawings and the like.

FIG. 1 is a plan view and a sectional view showing an embodiment of a wire pinching device for a winding machine according to the present invention.

FIG. 2 is a diagram showing the relationship between the wire clip and the bobbin. An X-movement table 3 is movably provided on the base 1 while being guided by a dovetail groove.

The base 1 is provided with an actuator 11 for X movement, and the actuator 11 for X movement moves the X movement table.

A pair of guide rods 4, 4 are slidably supported on the X-movement table 3.

A wire clamp support 5 is fixed to one end of the guide bars 4, 4, and a positioning plate 9 is fixed to the other end of the guide bars 4, 4.

A pair of wire clips 7, 7 is mounted on the wire clip support stand 5.

The wire clipper 7 has a movable finger 7b driven by the wire clipper actuator 6 and a fixed finger 7a.

Figure 1 shows the fingers in an open position.

The center portion of the X moving table 3 is thinner than the portion that receives the pair of guide rods 4, and the main body portion of the Y drive actuator 12 is fixed to that portion.

The tip of the rod 12a of the Y drive actuator 12 is connected to the wire clamp support 5, and the Y drive actuator 12 allows the assembly of the guide rods 4, 4, support 5, and positioning plate 9 to the left and right in the figure. be moved in the direction

The positioning plate 9 is provided with an actuator 10 for adjusting the distance, and the tip of the rod of the actuator 10 for adjusting the distance has a head 1 made of an elastic material.
0a is provided.

This state shows the state in which the head 10a protrudes.

Line pinch actuator 6, 6, spacing adjustment actuator 10, Y drive actuator 1
2. The X movement actuators 11 are each connected to a pneumatic circuit (not shown), and are driven to hold or cut the winding.

The winding is carried out by attaching the bobbin 16 to the spindles 2, 2, rotating the spindles 2, 2 at high speed, and supplying the winding 18 through the nozzles 20, 20.
It will be done.

During this winding, the wire clips 7 and 7 are connected to the nozzle 2.
It has been evacuated so that it does not interfere with 0's movement.

Finish the winding and attach the bobbin 16 as shown in FIG.
Winding wire 8 is tied around pin 16a of. This intertwining is performed by the nozzle 20.

When the intertwining is finished, insert the wire clip 7 in the position shown in Figure 2.
to advance. This movement is performed by the Y drive actuator 12.

At this time, the head of the elastic material of the spacing adjustment actuator 10 has been retracted from the position shown in FIG. 1, and the line clip 7 is brought to the position closest to the spindle.

By moving the spindle 20 to bring the winding 18 between the fixed finger 7a and the movable finger 7b of the wire clamp 7 and actuating the wire clamp actuator 6,
The winding 18 is sandwiched between each finger. FIG. 2 shows this state.

When the X-movement actuator 11 is driven in this state, the X-movement table 3 is moved upward in the plan view of FIG. 1, thereby cutting the winding 18.

For the next winding, the wire clip 7 is brought to the pin 16b side of the bobbin 16. At this time, the part 10a of the actuator 10 for adjustment is in the position shown in FIG.
In a state in which the rear end of the movable table abuts the portion 10a, the wire clip 7 is made to correspond to the pin 16b side of the bobbin 16.

In this state, the winding 18 is held between the wire clippers 7 and the nozzle 20 is used to connect the winding 18 to the terminal pin 16b.
can be tied to. Furthermore, the winding can be cut in the same manner as described above for other terminal pins that are set up on the same collar as the coil bobbin on which the terminal pin 16b is set and that have their windings tied off.

Various modifications can be made to the embodiments described in detail above within the scope of the present invention.

Although the embodiments described above have shown two spindles and two corresponding wire clips, more windings can be carried out simultaneously.

It is also possible to use a wire clipper with three fingers to hold two types of windings, as previously proposed by the inventor of the present invention.

Although we have shown an example of a pneumatically controlled actuator,
It is also possible to substitute other types of actuators.

(Effect of the invention) The position of the wire clipping according to the present invention can be moved and placed in multiple positions for each of multiple spindles, so the position of the pin on which the bobbin is planted is the same as the position of the pin on the spindle. Even if there are multiple positions in the axial direction, the wire clipping can be brought to the optimal position.

Moreover, this operation can be carried out using an air cylinder, for example, in which the movable part advances and retreats, which is suitable for cutting the winding wire and quickly moving a relatively long stroke to retract the wire pincher during the winding. It has been realized.

Therefore, by using this example,
Since the wire clipper can be moved quickly, including the cutting of a plurality of windings, it is possible to shorten the time for the entire process of fully automated winding and facilitate reliable cutting of the windings.
