The wire member holding member 75 is biased in the direction of D 1, that is, in a direction away from the guide member 74.
[0025]
When the movable plate 61 is moved in the direction of the arrow D2 by the cylinder device 60, the movable plate 61 and the wire holding member 75 come into contact with each other as shown in FIG. The state protrudes from the front.
From this state, when the movable plate 61 is moved in the direction of the arrow D1 by the cylinder device 60, the wire rod holding member 75 is moved forward by the biasing force of the coil spring 76 as shown in FIG. Immerse yourself from.
[0026]
Next, the coil forming operation by the winding machine 1 configured as described above will be described.
First, as shown in FIG. 5, the shaft member 18 is moved in the axial direction so that the tapered tip surface 21 a of the head member 21 provided at the tip of the shaft member 18 is in contact with the tip of the core member 32. As shown in FIG. 5, a partition member 33 having a tapered surface 33 a facing the tapered tip end surface 21 a of the head member 21 is provided on the core member holding mechanism portion 31 side.
[0027]
In this state, the tip end portion of the wire rod a fed out from the wire rod nozzle 20 is clamped by the biasing force of the coil spring 57 between the clamp portion 55b of the clamp member 55 and the front surface 53a of the guide member 53 described above.
When the tip of the wire a fed from the wire rod nozzle 20 is clamped, the shaft member 18 is rotated to turn the wire rod nozzle 20 around the core member 32.
As a result, the wire a is wound around the tip of the core member 32. At this time, the wire a is reciprocated in the directions of arrows E1 and E2 shown in FIG. 5 by being guided by the tapered tip surface 21a of the head member 21 and the tapered surface 33a of the partition member 33, and the coil C Is formed.
When the coil C around which the wire a having a predetermined length is wound is formed, the rotation of the shaft member 18 is stopped.
[0028]
In this state, the wire a drawn out from the winding end position of the wire a constituting the coil C is connected to the wire nozzle 20, and the coil C is removed from the core member 32 unless the drawn wire a is cut. It cannot be extracted. Below, the cutting | disconnection operation | movement of the wire rod a pulled out from the winding end position of the wire rod a which comprises the coil C is demonstrated.
[0029]
First, in the state in which the coil C is formed, as shown in FIG. 2, the tip end portion of the wire rod a is clamped by the clamp member 55, and is drawn out from the winding end position of the wire rod a constituting the coil C. The wire a is connected to the wire nozzle 20.
From this state, the movable plate 61 is moved forward by the driving of the cylinder device 60, and the wire cutting member 54 and the clamp member 55 are moved to the guide member 53 as shown in FIGS. 3 (a) and 4 (a). It is assumed that the wire protrudes from the front surface 53 a and the wire holding member 75 protrudes from the front surface of the guide member 74.
As a result, the wire cutting member 54, the clamp member 55, and the wire holding member 75 can come into contact with the wire a connected to the wire nozzle 20.
[0030]
Next, the wire rod nozzle 20 is swung in the direction of the arrow F shown in FIG. When the wire nozzle 20 turns, a part of the wire a between the winding end position of the coil C and the wire nozzle 20 is caught by the wire holding member 75 and held by the wire holding member 75 as shown in FIG. It becomes a state.
Further, as the wire nozzle 20 turns, the wire a held by the wire holding member 75 is further in contact with the wire cutting member 54 and the clamp member 55 as shown in FIG. When the wire rod cutting member 54 and the clamp member 55 are brought into contact with each other, the turning of the wire rod nozzle 20 is stopped.
[0031]
Here, the length of the wire a drawn from the winding end position of the coil C until it contacts the wire cutting member 54 is the distance La from the coil C to the wire holding member 75 and the wire holding member 75 shown in FIG. Is the sum of the distance Lb from the wire cutting member 54 to the wire cutting member 54. The length of the wire a drawn from the winding end position of the coil C until it comes into contact with the wire cutting member 54 is defined according to the installation positions of the guide member 53 and the guide member 74 on the support member 52.
[0032]
From this state, the movable plate 61 is moved rearward by driving the cylinder device 60, and as shown in FIGS. 3B and 4B, the wire cutting member 54 and the clamp member 55 are respectively turned into coil springs. It is made to immerse from the front surface 53a of the guide member 53 by the urging force of 56, 57 and 76.
At this time, the cutting blade 54a of the wire cutting member 54 cuts the wire a by moving with respect to the wire a in contact.
As a result, the length of the wire rod a drawn from the end position of the coil C becomes equal to the sum of the distances La and Lb.
[0033]
Further, when the clamp member 55 is immersed in the guide member 53, the wire a is sandwiched between the clamp portion 55b of the clamp member 55 and the front surface 53a of the guide member 53, and the wire a on the wire nozzle 20 side of the cut wire a. The tip is clamped.
[0034]
In this state, air heated from the hot air nozzle 37, that is, hot air is blown toward the coil C formed on the core member 32.
Thereby, the coating film formed on the wire a constituting the coil C is fused, and the wires a constituting the coil C are bonded to each other.
[0035]
Next, when the core member 32 is moved in the axial direction by the cylinder device 41 described above and immersed in the partition member 32 shown in FIG. 5, the coil C whose movement is restricted by the partition member 32 becomes the core member 32. The completed coil C is obtained.
[0036]
In this state, since the tip end portion of the wire rod a fed out from the wire rod nozzle 20 is clamped by the clamp member 55, a new coil can be formed.
[0037]
As described above, according to the present embodiment, the length of the wire a drawn from the winding end position of the coil C is the guide member 53 provided with the wire cutting member 54, the clamp member 55, and the guide member provided with the wire holding member 75. The length of the wire a drawn out from the winding end position of the coil C is adjusted to a predetermined length by appropriately adjusting the installation positions of the guide member 53 and the guide member 74. Can be easily done.
When it is desired to shorten the length of the wire a drawn from the winding end position of the coil C, the installation position of the guide member 74 provided with the wire holding member 75 is moved to a position as shown in FIG. Good. When the wire holding member 75 is moved as shown in FIG. 8, the winding end position Pb of the coil C is also moved. That is, the winding end position Pb of the coil C can be arbitrarily changed by moving the wire holding member 75.
Furthermore, when it is not desired to change the winding position Pb of the coil C, the winding position of the coil C is adjusted by adjusting the installation position of the guide member 53 including the wire cutting member 54 and the clamp member 55 with respect to the support member 52. Without changing the position Pb, only the length of the wire rod a drawn from the end position of the coil C can be changed.
[0038]
【The invention's effect】
According to the present invention, the length of the wire drawn from the winding end position of the wire constituting the coil can be cut to a predetermined length.
Moreover, according to this invention, it becomes possible to adjust arbitrarily the winding end position of the wire which comprises a coil.
