The crank member 50 has a revolution shaft 52 and a pair of crank arm portions 53a and 53b. The pair of crank arm portions 53a and 53b are connected to both ends of the revolution shaft 52, respectively. The crank member 50 is supported by the drive shaft 42 at one end (end B2 side) in the width direction Y and supported by the support shaft 54 at the other end (base end B1 side). As the drive shaft 42 rotates, the revolution shaft 52 of the crank member 50 rotates (revolves) around the axis L1 in a circular orbit. In other words, the axis L2 of the revolution shaft 52 revolves around the axis L1 as the drive shaft 42 rotates.

As shown in FIG. 6, the carrier 30 is attached to the holder 22 by inserting the revolution shaft 52 into the revolution shaft insertion portion 32c. More specifically, the conveying body 30 is attached to the holding body 22 in a state in which the revolution shaft 52 is inserted through the revolution shaft insertion portion 32c and is supported by the revolution shaft 52 at two points, the upstream A1 side and the downstream A2 side. It is Therefore, when an operation to rotate the operation part 44 is performed, the carrier 30 maintains a substantially horizontal posture while being supported by the revolution shaft 52, and moves in a circular orbit around the axis L1 (FIG. 7). reference). The carrier 30 is supported by the revolution shaft 52 so as to be slidable in the width direction Y. As shown in FIG.

The cam portion 62, the ball plunger 64, and the biasing member 66 are provided so as to correspond to the upstream link mechanism 40a and the downstream link mechanism 40b, respectively.

The biasing member 66 of this embodiment is a coil spring. The biasing member 66 is attached to the revolution shaft 52 . More specifically, as shown in FIG. 6, the biasing member 66 is attached to the revolution shaft 52 so as to be located between the carrier 30 and the holder 22 on the base end B1 side of the carrier 30. It is As shown in FIG. 3, the biasing member 66 is arranged to bias the carrier 30 from the base end B1 side to the distal end B2 side. In the following description, the direction in which the conveying body 30 is urged by the urging member 66 may be simply referred to as "biasing direction F". The conveying body 30 is supported by the revolving shaft 52 while being biased by the biasing force of the biasing member 66 in the direction (retraction direction y2) in which the operating portion 44 is provided.

The cam portion 62 is a member having a substantially circular shape when viewed from the front. As shown in FIG. 6, the cam portion 62 is attached to the carrier 30 . More specifically, the cam portion 62 is provided on the outside of the conveying body 30 in the width direction Y and on the side opposite to the side on which the biasing member 66 is provided (end B2 side).

As shown in FIG. 8, an end surface of the cam portion 62 is formed with an inclined surface 62a inclined from one side to the other side in the radial direction. The inclined surface 62a is formed as a surface whose height decreases from the upstream A1 side toward the downstream A2 side.

When the crank member 50 rotates about the axis L1 with the rotation of the drive shaft 42, the ball plunger 64 is displaced in a circular orbit about the axis L1. Further, as described above, the carrier 30 is attached to the revolution shaft 52 so as to be slidable in the width direction Y, and is biased by the biasing member 66 in the retracting direction y2 (biasing direction F). .

When the carrier 30 is displaced in a circular orbit as the drive shaft 42 rotates, the tip 64a of the ball plunger 64 moves in a circular orbit on the inclined surface 62a. Here, the ball plunger 64 is displaced in a circular orbit while maintaining its position in the width direction Y, while the carrier 30 is displaceable while being urged in the retracting direction y2 (biasing direction F). ing. Therefore, when the conveying body 30 is displaced so as to draw a circular orbit, the movement in the width direction Y depends on the position (the height of the cam portion 62) where the tip portion 64a of the ball plunger 64 and the inclined surface 62a contact each other. position is controlled.

8 ( A distance corresponding to the height difference (height D2 in FIG. 8(c)) in the range R1) of c) is offset. In this manner, when the conveying body 30 is displaced so as to draw a circular orbit, the position in the width direction Y is offset according to the contact position between the ball plunger 64 and the inclined surface 62a.

Next, the rotation angle of the drive shaft 42 and the position of the movable plate 34 (conveyor 30) when the operation portion 44 is rotated will be described with reference to FIGS. 7 and 8. FIG.

As described above, the conveying body 30 moves so as to draw a rotational orbit while maintaining a substantially horizontal posture with respect to the holding body 22 by rotating the operating portion 44 . In the processing apparatus 10 shown in this embodiment, the conveying body 30 is positioned at the lowest position when the handle portion 44a (not shown in FIG. 7) of the operating portion 44 is positioned at the highest position (see FIG. 7A). , the carrier 30 is positioned highest when the handle portion 44a of the operating portion 44 is positioned lowest (see FIG. 7(c)).

Further, as described above, when the driving shaft 42 is rotated by the rotating operation of the operating portion 44, the conveying body 30 is displaced so as to draw a circular orbit as the driving shaft 42 rotates. In other words, the carrier 30 changes its position in synchronization with the rotation angle of the drive shaft 42 . Therefore, in the following description, the rotation angle of the drive shaft 42 is simply referred to as "shaft rotation angle". In the drawings, the shaft rotation angles are simply shown as angles such as "90°" and "180°".

Further, the state in which the upper edge 35 of the movable plate 34 is most downwardly spaced from the upper edge 25 of the holding plate 24 is defined as "axis rotation angle 0 degree", and the drive shaft 42 is rotated in the forward direction (counterclockwise in FIG. 7). , and reaches the shaft rotation angle of 0 degrees (the drive shaft 42 makes one rotation) will be referred to as the "shaft rotation angle" corresponding to the angle at which the drive shaft 42 has rotated.

For example, the state in which the drive shaft 42 rotates in the positive direction (counterclockwise in FIG. 7) by 90 degrees from the shaft rotation angle of 0 degrees is simply referred to as "shaft rotation angle of 90 degrees", and the drive shaft 42 rotates in the positive direction from the shaft rotation angle of 0 degrees. The state in which the drive shaft 42 is rotated 180 degrees in the forward direction is simply referred to as "shaft rotation angle 180 degrees", and the state in which the drive shaft 42 is rotated 270 degrees in the positive direction from the shaft rotation angle of 0 degrees is simply referred to as "shaft rotation angle 270 degrees". The state in which the drive shaft 42 rotates 360 degrees in the positive direction from 0 degrees and reaches the shaft rotation angle of 0 degrees is described as "0 degrees of shaft rotation angle".

<About the movement of the movable plate>
As shown in FIG. 7( a ), the upper edge 35 of the movable plate 34 is located below the upper edge 25 of the holding plate 24 at the axial rotation angle of 0 degrees. When the operating portion 44 is rotated in the forward direction from the axial rotation angle of 0 degrees, the movable plate 34 is displaced upstream A1 so that the upper edge 35 approaches the upper edge 25 of the holding plate 24 .

Further, when the axis rotation angle is 0 degrees, the rectangular wire 2 is in a state in which two positions in the longitudinal direction are supported by the holding recesses 26 . That is, the rectangular wire 2 is held by the holder 22 by being fitted into the holding recesses 26 of the pair of holding plates 24 spaced apart in the width direction Y at two locations in the longitudinal direction. there is

As shown in FIG. 7(b), when the drive shaft 42 rotates from the axis rotation angle of 0 degrees and reaches the axis rotation angle of 90 degrees, the upper edge 35 of the movable plate 34 is aligned with the upper edge 25 of the holding plate 24. Reach approximately matching heights. Further, when the shaft rotation angle is 90 degrees, the upper edge 35 of the movable plate 34 and the upper edge 25 of the holding plate 24 are substantially aligned in the vertical direction H, and the holding recess 26 and the conveying recess 36 are positioned in the vertical direction H. , and the position in the transport direction X, the position substantially coincides.

At a shaft rotation angle of 90 degrees, the flat wire 2 comes into contact with both the holding recess 26 and the conveying recess 36 . is held by both the holding recess 26 and the transport recess 36 (see FIG. 11(b)). When the drive shaft 42 further rotates in the positive direction from the shaft rotation angle of 90 degrees and the movable plate 34 moves upward, the flat wire 2 held in the holding recess 26 is lifted up so as to be scooped up by the conveying recess 36. It will be in a state of being held by the carrier 30 (see FIG. 11(c)).

Further, as shown in FIG. 8(a), when the transfer body 30 has an axial rotation angle of 90 degrees, the tip portion 64a of the ball plunger 64 moves within the movement range R1 of the tip portion 64a (see FIG. 8(c)). , the highest portion of the inclined surface 62a is contacted. Therefore, the carrier 30 is most offset in the approach direction y1 when the shaft rotation angle is 90 degrees.

As shown in FIG. 7(c), when the drive shaft 42 rotates in the forward direction from the shaft rotation angle of 90 degrees, the movable plate 34 is further displaced upward. Note that the rectangular wire 2 is held by the carrier 30 (see FIG. 11(c)) while the shaft rotation angle reaches 270 degrees from the shaft rotation angle of 90 degrees. The carrier 30 moves above the holder 22 in a circular orbit while holding the rectangular wire 2 . Further, while reaching the shaft rotation angle of 270 degrees from the shaft rotation angle of 90 degrees, the conveying body 30 is displaced toward the downstream side A2 in the conveying direction X by the interval D1.

As shown in FIG. 7(d), when the shaft rotation angle is 270 degrees, the rectangular wire 2 again comes into contact with both the holding recess 26 and the conveying recess 36 (see FIG. 11(d)). When the drive shaft 42 rotates further in the positive direction from the shaft rotation angle of 270 degrees and the movable plate 34 moves downward, the flat wire 2 held in the conveying recess 36 is changed to the holding recess 26, and the holder is moved. 22 (see FIG. 11(f)).

Further, as shown in FIG. 8(b), when the conveying body 30 has an axial rotation angle of 270 degrees, the tip portion 64a of the ball plunger 64 is the lowest portion of the inclined surface 62a in the movement range R1 of the tip portion 64a. come into contact with Therefore, the carrier 30 is most offset in the separation direction y2 when the shaft rotation angle is 270 degrees. In addition, the flat wire 2 (not shown in FIG. 8) held by the carrier 30 is also offset in the retraction direction y2 together with the carrier 30 .

In this manner, the conveying device 20 displaces the conveying body 30 as the drive shaft 42 rotates, and lifts the flat wire 2 held in one of the holding recesses 26 by the conveying recesses 36 to be adjacent to the downstream A2 side. It is transported to the holding recess 26 .

Further, when the conveying body 30 moves in a circular orbit, the rectangular wire 2 is lifted at the position where the axis rotation angle is 90 degrees and the conveyance is started, and the rectangular wire 2 is moved to the position where the axis rotation angle is 270 degrees. The flat wire 2 is held in the holding concave portion 26, and the conveying is completed. In other words, the conveying device 20 starts conveying the flat wire 2 at the timing when the conveying body 30 is positioned on the approach direction y1 side (the timing when the shaft rotation angle is 90 degrees), and holds the flat wire 2. The flat wire 2 is held by the holder 22 from the carrier 30 while offsetting the carrier 30 in the separating direction y2.

In this manner, the conveying device 20 offsets the rectangular wire 2 away from the press device 100 in a series of processes of conveying the rectangular wire 2 . Therefore, when the flat wire 2 is conveyed from one holding recess 26 to the adjacent holding recess 26, the flat wire 2 may come into contact with the reference surface 114 described later or run over the positioning portion 112. can be suppressed.

Further, as described above, in the processing apparatus 10, the operation of feeding the flat wire 2 forward (the operation of displacing the conveying body 30 so as to draw a circular path) and the operation of offsetting the flat wire 2 (the conveying body 30 moving in the width direction Y). ) are synchronously performed by the rotation angle of the drive shaft 42 . Therefore, the configuration and control can be simplified without requiring a control device or the like for separately controlling these operations.

<Regarding the shape of the holding groove and the attitude of the rectangular wire>
Next, the attitude of the flat wire 2 when held in the holding recess 26 and the transport recess 36 will be described with reference to FIGS. 11 and 12. FIG. As described above, the rectangular wire 2 is transported downstream A2 from the state held by the holder 22 as the transporter 30 moves. More specifically, the flat wire 2 is transported from the holding recess 26 to the holding recess 26 adjacent to the downstream A2 side by the movement (displacement) of the transport body 30 .

The flat wire 2 is held with its peripheral surface in contact with the outer edge of each holding recess 26 and the outer edge of each conveying recess 36 (see FIGS. 9 and 10). Therefore, when the outer edge of the holding recess 26 and the outer edge of the conveying recess 36 are formed to be inclined with respect to the vertical direction, the rectangular wire 2 is held in a posture inclined according to the inclination angle of the outer edge. . Further, when the outer edge of the holding recess 26 and the outer edge of the conveying recess 36 are substantially horizontal or substantially vertical, the flat wire 2 is held vertically or horizontally.

The shape of the outer edge of each holding recess 26, the shape of the outer edge of the conveying recess 36, and the attitude of the rectangular wire 2 will be described below. In the following description of the shape of the outer edge of the holding recess 26 and the outer edge of the transport recess 36, the state viewed from the side on which the operation unit 44 is provided in the width direction Y of the processing apparatus 10 is referred to as "front view". and explain.

In the following description, the shapes of the holding recessed portion 26a, the holding recessed portion 26b, and the conveying recessed portion 36a when viewed from the front, and the holding recessed portion 26b from the state in which the flat wire 2 is held in the holding recessed portion 26a to the state in which the flat wire 2 is held in the conveying recessed portion 36a. A detailed description will be given of the posture during transport, and then the shape of each holding recess 26 and each transport recess 36 will be described.

The holding recess 26a is the holding recess 26 provided on the most upstream A1 side. The flat wire 2 cut out from the supply device 90 is held in the holding recess 26 . As shown in FIG. 9, the holding recess 26a is formed such that the outer edge thereof is inclined with respect to the vertical direction. Therefore, when the flat wire 2 is held in the holding recess 26a, the flat wire 2 is held in an inclined posture.

The conveying recessed portion 36a is the conveying recessed portion 36 provided on the most upstream A1 side. The conveying recess 36a lifts and conveys the flat wire 2 held in the holding recess 26a from below, and conveys the flat wire 2 to the adjacent holding recess 26b. As shown in FIG. 10, the outer edge of the conveying recess 36a has a larger inclination angle on the upstream A1 side than the inclination angle of the outer edge on the upstream A1 side of the holding recess 26a. When the rectangular wire 2 is held in the conveying concave portion 36a, the rectangular wire 2 assumes an inclined posture toward the vertical direction so as to lean against the outer edge on the upstream A1 side.

The holding recess 26b is the holding recess 26 provided on the downstream A2 side of the holding recess 26a. In other words, the holding recess 26b is the holding recess 26 adjacent to the holding recess 26a on the downstream A2 side. The outer edge of the holding recessed portion 26b is substantially U-shaped when viewed from the front, and has a width that substantially matches the short side surface 2b of the rectangular wire 2. As shown in FIG. When the flat wire 2 is held in the holding recess 26b, the flat wire 2 is supported by the outer edge formed so that the short side surface 2b contacts the bottom of the holding recess 26b and the long side surface 2a on the lower side rises. , in a vertical position.

As shown in FIGS. 11(a) and 11(b), when the conveying body 30 moves upward, the conveying recess 36 eventually reaches a height substantially matching the holding recess 26, and the flat wire 2 reaches the holding recess 26. As shown in FIGS. and the outer edge of the conveying recess 36 (the state of being supported by both). As shown in FIG. 11(b), when the flat wire 2 held in the holding recess 26a in an inclined posture is held in the conveying recess 36 so as to be scooped up from below, the flat wire 2 is held by the outer edge on the upstream A1 side of the backrest. , and is inclined toward the vertical direction.

As shown in FIG. 11(c), the carrier 30 moves in a circular orbit above the holding recesses 26 toward the downstream A2 side while holding the rectangular wire 2. As shown in FIG.

As shown in FIG. 11(d), when the conveying body 30 moves and reaches a position where the conveying recess 36a substantially coincides with the holding recess 26b, the rectangular wire 2 held in the conveying recess 36a is transported so that the long side surface 2a is transported. While being supported by the outer edge of the recess 36, it is guided to the holding recess 26b. Further, when the conveying body 30 moves further downward, the flat wire 2 is held in the holding recess 26 b in a vertical posture, and the conveying recess 36 separates from the flat wire 2 .

In this manner, the processing apparatus 10 conveys the flat wire 2 while changing its posture while bringing the peripheral surface of the flat wire 2 into contact with the outer edge of the holding recess 26 and the outer edge of the transport recess 36 .

12A and 12B are diagrams showing a change in posture when the rectangular wire 2 is forwardly fed from the upstream A1 side to the downstream A2 side. As shown in FIG. 12, in the conveying device 20, when the holding recess 26 is switched to the carrying recess 36, or when the holding recess 36 is switched to the holding recess 26, the rectangular wire 2 is shifted within a range of approximately 45 degrees. I am trying to change.

More specifically, the conveying device 20 has an angle of the outer edge of one holding recess 26 and a conveying recess 36 that comes into contact with the flat wire 2 when the conveying body 30 lifts the flat wire 2 from the holding recess 26. The angle of the outer edge does not exceed the range of approximately 45 degrees, so that the change in posture of the flat wire 2 when the flat wire 2 is changed is reduced. Specifically, in the conveying device 20 of the present embodiment, the change in posture (change in inclination of the flat wire 2) when the flat wire 2 is re-held is within a range of approximately 45 degrees.

12 shows the attitude of the rectangular wire 2 when it is held in each of the holding recesses 26 and each of the conveying recesses 36, and also shows the presence or absence of a cutting process or the like performed in each of the holding recesses 26. As shown in FIG. For example, the holding recessed portion 26a corresponds to a position (cutting position) where the flat wire 2 is held when the flat wire 2 is cut out from a supply device 90, which will be described later. there is

The holding recessed portion 26b, the holding recessed portion 26d, the holding recessed portion 26e, the holding recessed portion 26g, and the holding recessed portion 26i correspond to positions (process positions) where cutting is performed by the pressing device 100 described later. ” is indicated.

Furthermore, the holding recess 26c, the holding recess 26f, and the holding recess 26h correspond to positions (idle process) where the cutting process is not performed by the press device 100, and are indicated as "idle process" in FIG.

The idle process is provided between the first cutting process and the second cutting process, between the third cutting process and the fourth cutting process, and between the fourth cutting process and the fifth cutting process. In the processing apparatus 10 of the present embodiment, an idle process (a process in which machining such as cutting is not performed) is provided while the flat wire 2 is sequentially fed from a cutting process to the next cutting process. By changing the posture of the rectangular wire 2, the posture can be changed more smoothly and reliably.

More specifically, the processing apparatus 10 relatively reduces the number of changes in attitude at one time when the rectangular wire 2 is held, and increases the number of times the attitude is changed. can be changed to the intended posture. In other words, in the processing apparatus 10, when it is necessary to change the orientation of the rectangular wire 2 significantly (for example, 90 degrees) between one cutting process and the next cutting process, the rectangular wire 2 is By distributing the angle for changing the posture several times, the posture of the rectangular wire 2 can be reliably changed.

For example, when the flat wire 2 is placed from the conveying recess 36 to the holding recess 26, inertial force acts on the flat wire 2 in the transport direction X due to the displacement of the transport body 30, and when the flat wire 2 is placed, the flat wire 2 may fall in the displacement direction of the carrier 30 (downstream A2 side, etc.). The processing apparatus 10 can suppress conveyance defects such as the flat wire 2 falling in an unintended direction when conveying such a flat wire 2, and can improve the reproducibility of the posture.

Next, the extrusion device 70 will be described with reference to the drawings. The pushing device 70 is provided to push the flat wire 2 in the abutting direction y1. As shown in FIG. 13, the extrusion device 70 includes an extrusion device main body 71 and a plurality of pushers 76 (eight in this embodiment). Further, as shown in FIG. 14, the extrusion device 70 includes an extrusion mechanism 80. As shown in FIG. In addition, as shown in FIG. 6, the pushing mechanism 80 is provided so as to correspond to the upstream link mechanism 40a and the downstream link mechanism 40b. 14 and 15 show the pushing mechanism 80 corresponding to the upstream link mechanism 40a, and the illustration of the pushing mechanism 80 corresponding to the downstream link mechanism 40b is omitted.

As shown in FIG. 13 , the extrusion device 70 has a configuration in which a plurality of pushers 76 are attached to a pusher connecting portion 74 of an extrusion device main body 71 . Further, the pusher main body 71 has a structure in which a slide plate 72 and a pusher connecting portion 74 are connected.

The pushing device 70 attaches and connects the plurality of pushers 76 to the pusher connecting portion 74 and attaches them to the slide plate 72 so that the plurality of pushers 76 can move integrally. The slide plate 72 is connected to an extrusion mechanism 80, which will be described later, and is displaceable so as to move back and forth in the width direction Y (see FIG. 15). Therefore, the processing apparatus 10 does not require individual actuators (cylinders, etc.) for activating each of the plurality of pushers 76, and the configuration can be simplified.

As shown in FIG. 13, the plurality of pushers 76 are arranged so as to line up in the transport direction X in the order of pushers 76a to 76h from the upstream A1 side. Further, the pushers 76a-76h are provided so as to correspond to the holding recesses 26b-26i. For example, the pusher 76a is provided to push out the flat wire 2 held in the holding recess 26b, and the pusher 76b is provided to push out the flat wire 2 held in the holding recess 26c.

Here, as shown in FIG. 13, the pushing device 70 is not provided with a pusher 76 at a position corresponding to the holding recessed portion 26a, and instead is formed such that the pusher connecting portion 74 is retracted in the retraction direction y2. A recess 74a is provided. In the processing apparatus 10 of the present embodiment, the holding recessed portion 26a is provided as the holding recessed portion 26 corresponding to the cutting step. Also, the rectangular wire 2 is cut out toward the retraction direction y2 and held. The receding portion 74a is provided so that the rectangular wire 2 held in the retracting direction y2 in the holding recess 26a and the pusher connecting portion 74 do not interfere with each other.

The pushing mechanism 80 is provided as a mechanism for moving the pushing device main body 71 back and forth in the width direction Y. As shown in FIG. As shown in FIG. 14, the pushing mechanism 80 has a crank portion 84, a link arm 86, and a guide portion 89. As shown in FIG. Further, a transmission mechanism 81 is provided in the pushing mechanism 80 .

The transmission mechanism 81 is provided to operate the pushing device 70 in conjunction with the movement of the carrier 30 of the carrier device 20 . The transmission mechanism 81 of this embodiment transmits the power of the conveying device 20 to the pushing device 70 via a plurality of gears (gears), and operates the conveying device 20 and the pushing device 70 in synchronization. .

More specifically, as shown in FIG. 14 , the transmission mechanism 81 includes a first gear 82 that is attached to the drive shaft 42 of the conveying device 20 and rotates integrally with the drive shaft 42 , and a second gear that meshes with the first gear 82 . A second gear 83 is provided, and rotational power of the drive shaft 42 is transmitted via the first gear 82 and the second gear 83 . In other words, the transmission mechanism 81 is arranged so that the axis L3 of the second gear 83 intersects (substantially orthogonally crosses) the axis L1 of the drive shaft 42, and the rotational power of the drive shaft 42 is transmitted. be done.

In addition, in the processing apparatus 10 of the present embodiment, the first gear 82 rotates once (360 degrees) in synchronization with the drive shaft 42 rotating once (360 degrees). In other words, in the processing device 10 , the extrusion device 70 operates in synchronization with the conveying device 20 that operates according to the rotation angle (shaft rotation angle) of the drive shaft 42 .

As shown in FIG. 14, the crank portion 84 has a shaft portion 84a and an arm portion 84b. The shaft portion 84a is arranged such that the axis L3 is oriented in the vertical direction H. As shown in FIG. Further, the shaft portion 84a of the crank portion 84 is connected to the second gear 83 so as to rotate integrally therewith. The link arm 86 is attached so as to connect the arm portion 84 b of the crank portion 84 and the connecting portion 88 of the slide plate 72 .

As shown in FIG. 15, when the crank portion 84 rotates around the shaft portion 84a, the connecting portion 88 moves in a circular orbit so as to be pulled by the crank portion 84, and the slide plate 72 moves along with it. Moving. Here, since the displacement direction of the slide plate 72 is regulated in the width direction Y by the guide portion 89, the slide plate 72 moves linearly in the width direction Y. As shown in FIG. Thus, the pushing mechanism 80 forms a crank/slider mechanism that linearly moves the slide plate 72 following the rotation of the crank portion 84 .

When the slide plate 72 is displaced (linearly) so as to move back and forth in the width direction Y, the plurality of pushers 76 are integrally displaced. The pushing device 70 can be moved integrally without stroking each of the plurality of pushers 76 . Therefore, it is not necessary to provide a control device or the like for displacing each pusher 76, and the structure can be simplified.

In addition, the extrusion device 70 can increase the maximum stroke amount (displacement distance D3 in FIG. 15) in the width direction Y by adopting a displacement mechanism that forms a crank-slider mechanism. More specifically, the pushing device 70 can push out the rectangular wire 2 linearly and has a larger stroke amount than when the pusher connecting portion 74 is configured to swing. be able to.

15 is a plan view showing the operation of the extrusion device 70. FIG. The extrusion device 70 operates in synchronization with the rotation of the drive shaft 42 as described above. In the following description, regarding the operation of the extrusion device 70, the axial rotation angle of the drive shaft 42 and the corresponding position of the pusher 76 will be described for each axial rotation angle. 15, the illustration of the drive shaft 42 is omitted.

As shown in FIG. 15(a), in the extrusion device 70, when the shaft rotation angle is 0 degrees, the connecting portion 88 is positioned closest to the base end B1 side, the stroke amount (displacement distance D3) is maximized, and the slide plate 72 is pushed out in the abutting direction y1. In this case, the tip portion 77 of the pusher 76 is positioned at the maximum stroke position Py1.

As shown in FIG. 15(b), the slide plate 72 is retracted while the drive shaft 42 rotates in the positive direction from the shaft rotation angle of 0 degrees, passes through the shaft rotation angle of 90 degrees, and reaches the shaft rotation angle of 180 degrees. Slide in direction y2.

As shown in FIG. 15(c), when the shaft rotation angle reaches 180 degrees, the coupling portion 88 is positioned closest to the distal end B2, the stroke amount (displacement distance D3) is minimized, and the slide plate 72 is positioned closest to the distal end B2. will be located on the side. In this case, the tip portion 77 of the pusher 76 is positioned at the minimum stroke position Py2.

As shown in FIG. 15(d), when the drive shaft 42 rotates in the positive direction from the shaft rotation angle of 180 degrees, passes through the shaft rotation angle of 270 degrees, and reaches the shaft rotation angle of 0 degrees again, the slide plate 72 is thrust. It slides in the hitting direction y1.

In this manner, the pushing device 70 linearly displaces the tip portion 77 of the pusher 76 back and forth in the width direction Y in synchronization with the rotation of the drive shaft 42 (according to the shaft rotation angle). When the shaft rotation angle is 0 degrees, the distal end portion 77 of the pusher 76 is positioned closest to the abutment direction y1 (maximum stroke position Py1). position (minimum stroke position Py2).

In the above-described series of operations, the extrusion device 70 positions the flat wire 2 by making the flat wire 2 offset in the retreating direction y2 by the offset mechanism 60 into the abutting direction y1. In addition, the pushing device 70 has a function of pushing the flat wire 2 cut out so as not to interfere with the guide post 116 so that the flat wire 2 reaches the reference plane 114, as will be described later.

Next, the supply device 90 will be described with reference to FIG. 16 and the like. The feeding device 90 is for stocking the flat wire 2 having a predetermined length, and cutting out the flat wire 2 one by one and feeding it to the conveying device 20 .

As shown in FIG. 16 , the supply device 90 includes a supply section 92 and a cutting member 91 . The cutting member 91 is attached to the supply portion 92 so as to be in a position where it can come into contact with the movable plate 34 .

The supply portion 92 can hold the flat wire 2 by a pair of supply plates 91c spaced apart in the width direction Y and stock the flat wire 2 . The supply part 92 has an appearance shown in FIG.

In the supply device 90 of the present embodiment, supply portions 92 are formed at the longitudinal ends of the holding plate 24 (see FIG. 5(c)). More specifically, as shown in FIG. 16, the supply section 92 of the present embodiment has a supply section forming section 92a formed at the end of the holding plate 24 on the upstream A1 side, and is clamped against the supply section forming section 92a. The supply plate 91c is formed by attaching the plate 92b, and the pair of supply plates 91c are arranged in the width direction Y. As shown in FIG. In addition, in the processing apparatus of the present invention, the supply section may be configured separately from the holding plate.

As shown in FIG. 17, the supply portion 92 (supply plate 91c) is formed with a stock area 93, a dispensing area 94, a stopper portion 95, and a slide hole 97. As shown in FIG.

As shown in FIG. 17, the stock area 93 is an area surrounded by the supply plate 91c. A rectangular wire 2 having a predetermined length can be stocked in the stock area 93 . The stock area 93 is formed at a position higher than the position where the holding recess 26 is arranged in the vertical direction H of the processing device 10 .

As shown in FIG. 17, the dispensing area 94 is formed as a gap (slit) between the supply portion forming portion 92a and the holding plate 92b. More specifically, the dispensing area 94 is formed so as to be continuous from the stock area 93 and is formed as a gap that slopes downward toward the holding recess 26 . Also, the payout region 94 is formed so that the distance between the gaps substantially coincides with the distance of the rectangular wire 2 in the lateral direction. Therefore, when the flat wire 2 held in the stock area 93 reaches the vicinity of the entrance of the payout area 94, it falls by its own weight so as to slide down along the slope of the payout area 94 in a posture inclined toward the upstream A1 side.

Further, a stopper portion 95 is formed in the supply portion 92 at a position below the dispensing area 94 . The stopper portion 95 is formed as a step that substantially matches the length of the short side 4 b of the rectangular wire 2 . Therefore, the rectangular wire 2 that has slid down from the stock area 93 through the dispensing area 94 and reached the stopper portion 95 contacts the stopper portion 95 and is restricted from moving downward. The clamping plate 92b is formed with a concave portion at a position above the stopper portion 95 so that the flat wire 2 does not interfere with the flat wire 2 when the flat wire 2 passes over the stopper portion 95 and is cut out.

The slide hole 97 is formed in the supply portion forming portion 92a as an elongated through hole. In the supply device 90 of this embodiment, two slide holes 97 are arranged side by side so as to be inclined toward the downstream A2 side. The slide hole 97 is formed so as to intersect (substantially orthogonally cross) the inclination of the dispensing area 94 .

The cutting member 91 is provided for cutting out the rectangular wire 2 one by one. As shown in FIG. 16, the cut-out member 91 is a substantially rectangular plate-like member. As shown in FIG. 16 , insertion portions 91 a are provided at both ends of the cut-out member 91 . The cut-out member 91 is attached to the supply portion 92 at both ends in the longitudinal direction by inserting the insertion portion 91 a into the slide hole 97 .

The cut-out member 91 is displaceable along the axis L4 of the slide hole 97 . Specifically, the cut-out member 91 can be displaced obliquely upward (obliquely upward toward downstream A2) along the axis L4 of the slide hole 97 from the lower position.

As shown in FIG. 18( a ), when the cutting member 91 is positioned downward (when the height does not reach the payout region 94 ), the rectangular wire 2 positioned in the payout region 94 is positioned at the stopper portion 95 movement is restricted.

As shown in FIG. 18(b), when the cutout member 91 moves upward to reach the payout area 94, the cutout member 91 lifts the flat wire 2 adjacent to the stopper portion 95 upward. As a result, the flat wire 2 climbs over the stopper portion 95 and falls under its own weight so as to slide down into the holding recess 26a. In this way, the supply device 90 can cut out the flat wire 2 one by one and supply it to the holding recess 26a.

Further, the cut-out member 91 is arranged at a position where it can come into contact with the jaw portion 98 of the carrier 30 . When the conveying body 30 is displaced (when the conveying body 30 is displaced upward), when the jaw portion 98 of the conveying body 30 comes into contact with the cut-out member 91, the cut-out member 91 is lifted upward to the discharge area 94. A flat wire 2 is cut out.

Specifically, as shown in FIG. 19, the jaw portion 98, which was positioned away from the cut-out member 91 at the shaft rotation angle of 90 degrees, reaches the shaft rotation angle of 150 degrees as the carrier 30 is displaced. Starting to lift the cutting member 91 (see FIG. 19(b)). In this way, when the operating portion 44 is rotated in the forward direction, the supply device 90 is rotated after the conveying body 30 starts conveying (at a shaft rotation angle of 90 degrees) (in this embodiment, at a shaft rotation angle of 150 degrees). At the timing of , the jaw part 98 starts to lift the cutout member 91 .

Further, as shown in FIG. 19G, when the operating portion 44 is rotated in the forward direction, the supply device 90 is set before the end of transportation by the transportation body 30 (axis rotation angle of 270 degrees) (this embodiment). Then, the jaw portion 98 ends the operation of lifting the cutting member 91 at the timing of the shaft rotation angle of 175 degrees.

In other words, during the period in which the flat wire 2 is held by the conveying device 20 and the flat wire 2 is not held in the holding recess 26a (between the shaft rotation angle of 90 degrees and the shaft rotation angle of 270 degrees), A series of operations for cutting out the flat wire 2 into the holding recess 26a is completed.

Next, the press device 100 (cutting device) will be described with reference to FIG. 20 and the like. The press device 100 is provided to cut the end of the flat wire 2 to remove the insulating coating 3 or to form a C-plane on the end of the flat wire 2 .

As shown in FIG. 20( a ), the press device 100 has a die 102 composed of an upper die 104 and a lower die 106 . The upper die 104 and the lower die 106 are positioned by guide posts 116 provided on both sides in the longitudinal direction of the press device 100 (both sides in the transport direction X).

A plurality of cutting process portions 108 are formed in the press device 100 at positions on the center line C passing through the centers of the pair of guide posts 116 . Five cutting process portions 108 are formed along the transport direction X in the press device 100 of the processing device 10 of the present embodiment. Each cutting process portion 108 is provided with a blade portion 110, and each cutting process portion 108 cuts the end portion of the rectangular wire 2 on the base end B1 side.

In other words, the press machine 100 of this embodiment is provided with a plurality of cutting process sections 108 for cutting the ends of the rectangular wire 2 in one die 102 . Therefore, the processing apparatus 10 of the present embodiment can cut the ends of the flat wire 2 through a plurality of cutting process units 108 while sequentially feeding the rectangular wire 2 in the conveying direction X. As a result, the processing apparatus 10 of the present embodiment can significantly reduce the cost of the entire apparatus compared to the case where a press device is provided for each cutting process.

As shown in FIG. 20(b), each cutting process portion 108 is provided with a positioning portion 112 for positioning the flat wire 2 in the longitudinal direction by bringing the end portion of the flat wire 2 into contact therewith. Further, the positioning portion 112 is provided with a reference surface 114 for positioning the flat wire 2 by contacting the end surface thereof.

The five cutting process parts 108 are a first cutting process part 108a, a second cutting process part 108b, a third cutting process part 108c, a fourth cutting process part 108d, and a fifth cutting process part 108d from the upstream A1 side to the downstream A2 side. They are arranged in order of the process part 108e.

In this embodiment, an example in which the press device 100 is provided with five cutting process units 108 is shown, but the processing device of the present invention is not limited to this. Specifically, the processing apparatus of the present invention can be appropriately set according to the rectangular wire prepared in advance or whether or not to form a C-plane at the end of the rectangular wire. For example, the cutting device (pressing device) of the processing apparatus of the present invention may have two, three, or six or more cutting process units. Moreover, the cutting process to be performed in each cutting process portion is not limited to that of the present embodiment, and the cutting process of the ends of the rectangular wire may be performed in any order.

The five cutting process parts 108 are provided at positions corresponding to the holding positions Px. Specifically, as shown in FIG. 20(b), the first cutting process part 108a is at the holding position Px2, the second cutting process part 108b is at the holding position Px4, the third cutting process part 108c is at the holding position Px5, The fourth cutting process portion 108d and the fifth cutting process portion 108e are provided at positions corresponding to the holding position Px7 and the holding position Px9, respectively.

In each cutting process section 108 , cutting of the end portion of the rectangular wire 2 is performed while the rectangular wire 2 is held in the holding recess 26 . For example, in the cutting process section 108 where the flat wire 2 is held in an inclined posture, the corners of the flat wire 2 are cut to remove the insulating coating 3 remaining at the corners (FIG. 21 ( See cutting lines S2 and S3 in a-1).

Further, in the cutting process section 108 where the flat wire 2 is held vertically or horizontally, the peripheral surface (long side surface 2a or short side surface 2b) of the flat wire 2 is cut to remove the insulating coating 3. Processing is performed, or processing is performed to form a C-plane at the end of the rectangular wire 2 (see cutting line S1 in FIG. 21(a-1)).

Further, in the cutting process section 108 where the flat wire 2 is held vertically or horizontally, the edge of the tip surface of the flat wire 2 is cut to form a C-plane on the tip surface of the flat wire 2. (see cutting line S4 in FIG. 21(a-2) and cutting line S5 in FIG. 21(a-3)).

In addition, in the processing apparatus 10 of the present embodiment, as described above, the flat wire 2 is supplied in a state in which the insulating coating 3 on the short side surface 2b of the peripheral surface is removed. In the processing apparatus 10 of the present embodiment, the five cutting process sections 108 remove the insulating coating 3 from the peripheral surface and the corners of the flat wire 2 in each of the cutting process sections 108, and the C surface is formed on the end of the flat wire 2. is formed, and the tip surface of the flat wire 2 is formed to have a substantially semicylindrical appearance (see FIG. 21(b)).

Here, as described above, in the processing apparatus 10 , the rectangular wire 2 is cut in the plurality of cutting process units 108 provided in one press device 100 while the rectangular wire 2 is fed forward. Assuming that the rectangular wire 2 is conveyed straight along the conveying direction X from the supply device 90 toward the cutting process section 108 , the rectangular wire 2 interferes with the guide post 116 .

In the processing device 10, the rectangular wire 2 cut out from the supply device 90 is supplied in a retracting direction y2 relative to the rectangular wire 2 held at another holding position Px so as not to interfere with the guide post 116. . More specifically, as shown in FIG. 22(a), the rectangular wire 2 cut out from the supply device 90 (not shown in FIG. 22) to the holding position Px1 (holding recess 26a) is conveyed substantially straight as it is. It is cut out at a position (cutting position Py3) where it does not interfere with the guide post 116 even if it moves in the direction X.

Further, in the processing device 10, the stroke amount (displacement distance D1) of the extrusion device 70 is sufficiently ensured. In other words, the processing apparatus 10 has a stroke amount (long stroking has been achieved). Therefore, the processing apparatus 10 of the present embodiment solves the problem of interference between the guide post 116 and the rectangular wire 2 while performing a plurality of cutting processes with one press apparatus 100 .

Specifically, as shown in FIG. 22(a), the flat wire 2 is cut at a position (cutting position Py3) at which the end on the base end B1 side is separated from the center line C of the guide post 116. As shown in FIG. Further, as shown in FIG. 22(b), the flat wire 2 is offset by a distance D2 in the retracting direction y2 from the cutting position Py3 by the conveying device 20 and conveyed downstream A2 (see FIG. 8, etc.).

As shown in FIG. 22(c), the pushing device 70 enables a long stroke from the minimum stroke position Py2 to the maximum stroke position Py1. Therefore, the flat wire 2 cut away from the guide post 116 can be pushed out and positioned so as to reach the position (contact position Pt) where it contacts the reference surface 114 .

As described above, in the processing apparatus 10 , while providing a plurality of cutting process sections 108 in the press apparatus 100 , the rectangular wire 2 is cut out so as not to interfere with the guide post 116 of the press apparatus 100 , and then cut so as to reach the cutting process section 108 . A flat wire 2 can be extruded to

As a result, the processing device 10 moves the cut flat wire 2 from the cut position (cutting position Py3) to a position reaching the contact position Pt when the cut flat wire 2 is fed forward to the press device 100. A separate mechanism such as a device is not required. In other words, the extrusion device 70 of the processing device 10 has the function of abutting the flat wire 2 offset in the retraction direction y2 against the reference surface 114, and the flat wire 2 extending from the cut position to the contact position Pt. 2, and it is not necessary to provide a separate device to realize these functions.

<Regarding the operation of the entire processing device>
Next, the operation of each component of the processing apparatus 10 according to the shaft rotation angle will be described in chronological order. In FIG. 23, the drive shaft 42 rotates forward from a shaft rotation angle of 0 degrees, passes through a shaft rotation angle of 90 degrees, a shaft rotation angle of 180 degrees, and a shaft rotation angle of 270 degrees, and then returns to a shaft rotation angle of 0 degrees. It is a timing chart which shows operation|movement of each structure until it reaches 90 degrees.

As shown in FIG. 23, the rectangular wire 2 is held by the holder 22 when the shaft rotation angle is 0 degrees. In the process from the shaft rotation angle of 0 degrees to the shaft rotation angle of 90 degrees, the carrier 30 rises, and the flat wire 2 is started to be conveyed by the carrier 30 from the shaft rotation angle of 90 degrees.

As described above, the processing apparatus 10 is offset in the separation direction y2 when the flat wire 2 is conveyed downstream A2 by the conveying body 30. As shown in FIG. Therefore, at the time of completion of transportation, the rectangular wire 2 is offset in the retraction direction y2 from the position at the start of transportation. As a result, the processing apparatus 10 can suppress the occurrence of transport failures such as the transported rectangular wire 2 riding on the positioning portion 112 .

Further, while the rectangular wire 2 is being transported by the transport body 30 (during transport), the rectangular wire 2 is not held in the holding recess 26 (holding recess empty). The processing apparatus 10 cuts the flat wire 2 from the supply portion 92 into the holding recess 26 a while the flat wire 2 is not held in the holding recess 26 . Specifically, the processing apparatus 10 cuts out the flat wire 2 by the jaw portion 98 lifting the cutting member 91 between the timing when the shaft rotation angle is 150 degrees and the timing when the shaft rotation angle is 170 degrees (Fig. 18, see FIG. 19).

After the conveying body 30 completes conveying the rectangular wire 2, the processing device 10 strokes the extrusion device 70 in the abutting direction y1. At the timing of the axial rotation angle of 0 degrees, the pusher 70 presses the flat wire 2 against the flat wire 2 to press the flat wire 2 against the reference surface 114 to position the flat wire 2 in the width direction Y.

After the positioning of the rectangular wire 2 is completed, the cutting of the rectangular wire 2 is performed by the pressing device 100 .

As described above, the processing device 10 offsets the rectangular wire 2 and operates the extrusion device 70 and the feeding device 90 in synchronization with the conveying operation of the rectangular wire 2 by the carrier 30 . In other words, the processing apparatus 10 positions the flat wire 2 and cuts out the flat wire 2 so as to synchronize with the rotation of one axis (drive shaft 42).

In the above-described embodiment, an example in which the drive shaft 42 is rotated by the rotation operation of the operation unit 44 was shown, but the processing apparatus of the present invention rotates the drive shaft using a power source such as a motor. can be anything.
