, 336.

Next, the operation of this device will be explained. In this device, the press rod 245 and the die holder 287 move along the center line CL in the pallet transport direction as the pallet 153 moves intermittently.
For I, press rod 245 and die holder 287
The press tip 248 of the press rod 245 and the die plate 291 of the die holder 287 face each other and rotate in phase while the press tip 248 of the press rod 245 and the die plate 291 of the die holder 287 face each other and rotate in phase. The die holders 287 are brought close to each other, and the supplied wire CW is bent by the press tip 248 and the die plate 291 at the tips, respectively, and the proximal parts A and A of the end rings R of the ring nets N1 and N2 are bent by the wire CW. and a wire connecting operation that connects the 22nd rotatably.
Steps P1 and P2, which will be described later, connect the end rings of the left and right ring nets N1 and N2 shown in the figure with wires CW,
The ring nets N1 and N2 are connected by repeating the connection operation with P3 and P4 as one cycle. The end rings R of the ring nets N1 and N2 are positioned in advance in the positioning portions 159 of the ring nets of the left and right pallets 153L and 153R. First, the wire connection operation will be explained. In FIG. 20, the timing diagram related to the wire connecting operation is the vertical movement of the press rod and the die holder, and the wire tension, and the radial cam 23
8.238E, eccentric roller 309 makes one rotation (360 degrees)
By doing so, one cycle is completed, and this one cycle is repeated at each of the steps P1 to P4, so only step P1 will be explained. A description will be given starting from a state in which the wire wire w is already in contact with the tip of the wire stopper 277 by the wire supply device 300. still,
Since the die holder 287 is at the lower end in FIGS. 18(a) to 18(e), illustration thereof is omitted. At timing SO, the die holder 287 is at the lower end, the press rod 245 is at the upper end (FIG. 18(a)), and the main shaft 142
The radial upper cams 238 and 238E are rotated by the drive from the upper mold device 201, and the head main body 204 is guided by the guide rod 203 through the cam follower 207 of the upper die device 201 and starts to descend. 252
The press rod 245 with a . At this time, the preliminary bending die 269 is at its forward end position. The wire wire W located above the pre-bending mold body 269 is cut by the shearing force of the press member 252 between the outer periphery of one of the holding members Q 252 a of the press member 252 and the inner circumferential surface of the sleeve 260. The wire CW of a predetermined length is the 18th
It is pressed down onto the lower end mold 269a as shown in Figure (b).

In this way, a predetermined length of wire CW is fed so as to face the two rings R above and cross over their approach parts A, A. The pressed down wire CW is connected to the press groove 253 of the press member 252 and the lower end mold 26 of the preliminary bending mold body 269.
9a, its opposite end portions CWb (shown in FIG. 21) are slightly bent downward (FIG. 18(C)). Immediately after this state, the inclined surface 284 at the tip of the camshaft 282 begins to engage with the cam follower 274 of the lever 270, and the preliminary bending die 269 gradually retreats. Pre-bending mold body 269
While the lower end die 269a of the press member 252 is located directly below the press member 252, the press member 252 cannot be lowered, but the press rod 245 moves downward while resisting the force of the spring 258.
18(d)), the end lower die 269a of the preliminary bending die 269 is lowered relative to the press member 25.
When the intermediate lower die 269b is located directly below the wire CW, the press member 252 is suddenly lowered relative to the press rod 245 by the spring force of the compressed spring 258, and the wire CW with both ends bent is formed into a ring. A wire CW extends inside the ring R across the approach part A of the ring R.
The bent part CWa is bent inward from the part facing the ring R, and is formed into a mouth shape with a large downward opening (
18(e)), the press rod 245 and the press member 252 are slightly lowered until the intermediate lower die 269b is removed from directly below the wire CW, and the wire C is pre-bent.
W is sufficiently pushed into the tip sliding groove 256 of the holding gl 252a at the tip of the press member 252, and the wire CW, which has been pre-bent by the elastic force of the wire CW (the force that tends to expand after being bent), is pressed into the press member. 252, the intermediate lower die 269b comes off from directly under the wire CW,
It further descends (timing SL shown in FIG. 18(f) and FIG. 20). Until this time, the die holder 287 is located at the lower end.

Then, as the press member 252 further descends while holding the wire CW, the head main body 2 of the lower die device 202
04E is the radial cam 238E together with the die holder 287.
The rise of the die holder 2.87 is temporarily stopped. At this time, the plunger 294 of the die holder 287
The upper end is located exactly on the same plane as the upper edge of the end ring R (that is, the same plane as the upper surface of the pallet 153), and the end that is floating in the slit 154 space of the pallet 153 in the ring holding groove 299 of the plate-shaped protrusion 295 A part of the ring R is fitted (FIG. 18(g), timing S2).

While the die holder 287 is stopped (from timing S2 to S33), the press rod 245 continues to descend, and the plate-like protrusion 295 at the upper end of the plunger 294 enters between the two retaining walls 252a of the press member 252. The lower end surface of the press member 252 is the holder head 2 of the die holder 287.
It comes into contact with the upper end surface of the plate-like protrusion 289 of 87b (FIG. 18(h)).

In this way, the press rod 245 further descends while the press member 252 is stopped from descending, and the press rod 245 is further lowered.
A press tip 248 integrated with 45 lowers the wire CW, which has been opened downward into a mouth shape by preliminary bending, with its inner side surface 250 so as to surround the bent portion CW a of the wire CW so as to surround the approach portion A of the ring R, respectively. It is bent to the side and deformed into a substantially perfect shape (Fig. 18(i), timing S3). When deforming into a mouth shape in this way, a downward force is applied to the plunger 294 via the ring R, but since the plunger 294 is urged upward by a predetermined spring force of the spring 298, the plunger 294 descends. do not. At timing S3, the die holder 287 is raised again by the radial cam 238E, and before timing S4 is reached, the tip of the wire CW is bent inward along the arc surface 291a of the die plate 291, and the wire CW is bent downward. A portion CWa surrounds the approach portion A of the ring R. At this time, both ends of the wire CW are pre-bent in advance, and this pre-bent portion is connected to the die plate 2.
91, the bent portion CWa of the wire CW is bent inward into an arc shape with an inner diameter slightly larger than the thickness, and the tip surfaces of both ends of the wire CW are bent to the outer periphery of the wire CW. When they come into contact with each other, the final bevel is completed, and at that time, as shown in FIG. formed, end ring R and ring R
are rotatably connected via wire CW (timing 84 in FIG. 18(j)). The press rod 245 is located at the lower end from timing S3 to timing S85. After timing S5, the press rod 245 and die holder 287 move up and down, and the press rod 245 returns to the rising end at timing S8 through timings S6 and S7, and maintains this state until timing SO of step P2. On the other hand, the die holder 287 reaches the lower end at timing S9 and waits for the rise in the next step P2.

Here, the operation of the wire supply device 300 will be explained.

The wire wire W is connected to the wire feed roller 3 of the feed device 302.
26 and a biasing roller 330. During the period from timing SO to timing S1, the tip of the wire wire W is cut as described above, and the cut tip of the wire wire W is in contact with the outer periphery of the press member 252, and this contact state is as follows. It is only released immediately before the timing S8. Therefore, even if the wire feed roller 326 is rotated from the main shaft 142 via the chino 321 from the timing SO to the timing S8, slipping occurs between the wire feed roller 326 and the urging roller 330.
Wire line W is not sent. In addition, the wire feed roller 326
The urging roller 33o and the like are attached to the holding body 265 as described later.
However, since the feed drive shaft 317 and the spline sleeve 316 are spline-fitted,
Even when shifted, the wire feed roller 326 is rotated. Now, with the rotation of the main shaft 142, the eccentric roller 309 at timing SO starts rotating from a state slightly past the slack position to the tension position.

At timing S10, the tension position shown in FIG. ) is rewound. Then, when the timing S8 is reached, the eccentric roller 3
09 is located at the slack position again, and until this time the wire line W
Since the wire wire W is not fed, the wire wire W is loosened by a predetermined amount unwound from the drum 303. Then, between timing S8 and timing SO, the wire wire W is fed into the upper molding device [201] via the wire guide 279 and the like by the action of the wire feed roller 326 and the urging roller 330. At this time, since the wire wire W is unwound from the drum 303 as described above, there is an advantage that the wire wire W can be reliably supplied even when the wire wire W is wound on the drum 303 and the inertia is large.

Next, the shift rotation operation will be explained together with the pallet intermittent movement operation. In FIG. 20, the timing diagram related to the shift rotation operation and the pallet intermittent movement operation is the rotation of the press rod, the die holder, the left and right movement, and the pallet 1 movement.
~It's a send-off. These are upper and lower cylindrical cams 208.
208E shift 1 to groove 215, 21.5E, rotation groove 21
6, 216E, and in order to perform the steps P1 to P4 in one rotation of the pitch feed groove 118 of the drum 112 of the transfer device 100, one cycle of these operations is four times the vertical operation cycle of the press rod, etc. . As mentioned above, the head bodies 204 and 204E move up and down, but the spline shaft 22
3.223E, the rotation of the main shaft 142 is transmitted to the upper and lower cylindrical cams 208.208H. First, regarding the shift and rotation of the press rod 245, from the timing 0 to the timing SL after the timing S6.
1, the press rod 245 is moved as shown in FIG.
), the rotation axis PC is positioned to the left of the center line CLI in the pallet transfer direction when viewed from above (left shift state), and the press tip 248 at the tip of the press rod 245 at this time is positioned in the vertical plane CL2. located within (
(vertical left state where the press tip 248 intersects perpendicularly with the center mcL1 in the pallet transfer direction). When the timing SO of step P2 is reached, the rotation axis pc of the press rod 245
becomes on the center line CLI in the pallet transfer direction (shift is O), and this state continues until timing S7. In this state, until timing S1, the press tip 248 is on the vertical plane C.
It is located within L2. Then, as shown in FIG. 19(b), by the time the timing S2 is reached, the cam follower 24
6, the press rod 245 is rotated by a predetermined angle θ (60 degrees) to the left about its rotation axis PC (counterclockwise rotation state), and the press tip 248 diagonally intersects the vertical plane CL2 until timing S6. Retained. Thereafter, when the press rod 245 passes through timing S7 and reaches timing SO of step P3, its rotation axis P is to the right of the center line CL1 in the pallet transfer direction, as shown in FIG. 19(c).
C (shifted to the right), and the press tip 248 at the tip of the press rod 245 is aligned with the vertical plane CL.
Located within Z (right vertical state). This state continues until timing S12. Next, when the timing So of step P4 is reached, the rotation axis PC of the press rod 245 becomes on the center line CLI in the pallet transfer direction (shift o), and this state continues until timing S7. In this state, the press tip 248 is located within the vertical planes C and L2 until timing S1. Then, as shown in FIG. 19(d), the press rod 245 is rotated 60 degrees to the right around the rotation axis PC of the press rod 245 due to the movement of the cam follower 246 (in a clockwise rotation state) by the time S2 is reached. s
), the press tip 248 diagonally intersects the vertical plane CL2 and is held until timing S6. Thereafter, the press rod 245 passes through timing S7 and returns to timing SO of step P1. In each step P1 to P4, between the timing So and 81, the press rod 245
is not rotated, the press tip 248 at the tip is always located within the vertical plane CLZ, the wire wire W to be supplied is located directly below the press tip 248, and the wire wire W is not rotated until it is pre-bent. , retention takes place during this time.

Next, the operation of the die holder 287 will be explained.

Similarly to the press rod 245, the die holder 287 also has
Shift groove 215F, rotation groove 216E and shift member 241
E, cam followers 242E, 246 of die holder 287
Shift rotation is performed by engagement of E. The shift rotation of the die holder 287 is shifted to the left between timing So and timing S14, and the rotational state is in the left vertical state from timing S13 (FIG. 19 (a)), and is shifted to O from timing S15 to S17, and the rotational state is leftward from timing 816. Rotation state (
(Fig. 19(b)), from timing 318 to S20, the rotation state is shifted to the right and the rotation state is right vertical from timing S19 (Fig. 19 (c)), and from timing 821 to S23, the shift is 0 and the rotation state is clockwise rotation from timing S22. State (first
9(d)), and corresponding to the steps P1 to P4, timings 813 to 814, timings 816 to SL7, and timings S19 to S
20, and between timings 822 and 823, the press rod 245 is in a synchronized shift state and rotation state,
Further, during this timing, the main bending operation of the wire connecting operation is performed.

In the pallet feeding operation, rotation from the main shaft 142 is transmitted to the prime mover 127 via the transmission shaft 140 and bevel gears 138, 134, 131, and the cam follower 128 of the prime mover 127 engages with the index groove 124 of the Geneva wheel cart 25. When engaged, the Geneva wheel 125 is rotated 90 degrees.

Intermittent rotation of Geneva wheel 125 is caused by transmission sprocket 1
23, and is transmitted to the drive sprocket 119 of the drum 112 via the tension sprocket 121 and the like. The drum 112 is intermittently rotated by this intermittent rotation, and due to the engagement of the pitch feeding cam groove 118 and the cam followers 167 of the left and right pallets 153L and 153R, the drum 112 is rotated intermittently at timing 5o-32.
Looking at the pallet 153L between timings 825 and 826, its rectangular cutout 157 coincides with the vertical plane CL2 (FIG. 19(a)), and the middle between the rectangular cutout 157 and the semicircular cutout 158 coincides with the vertical plane between timings 825 and 826. CL2 coincides with CL2 (Fig. 19(b)), and the semicircular arc cut portion 158 coincides with vertical plane CL2 between timings 827 and 828 (Fig. 19(,)).
, between timings 829 and 830, the middle of the rectangular cut section 157 and the semicircular cut section 158 coincides with the vertical plane CL2 (the first
9(d)) and stopped, and the timing 824~
19 (a) to (b) between timings 825, (b) to (c) between timings 826 and 827, and (c) to (d) between timings 828 and 829. , the state returns from (d) to (a) between timings 530 and 831, and intermittent transfer is performed with 1/2 of the ring pitch P being one pitch (p). The intermittent transfer start timing (S24.S26.S28.530) is slightly later than the timing S9 when the die holder 287 is located at the lower end, and the intermittent transfer stop timing (S25, S27
, S29.531) are slightly before the timing SO in each step P1 to P4.

Thus, the press rod 245. When the die holder 287 is in the middle of descending, rising, descending end, rising end, etc.
The die holder 287 rotates without interfering with the left and right pallets 153L and 153R, and is shifted left and right, and the phase of rotation of the two is made to match between a timing slightly after the die holder 287 starts rising and a timing slightly before completing its descent. While the left and right pallets are intermittently transferred at a pitch P and stopped, the press rod 245 and die holder 287 come into contact with each other, and the wire CW is bent between the press tip 248 at the lower end of the press rod 245 and the die plate 291 at the upper end of the die holder 287, and the step By repeating this cycle with P1 to P4 as one cycle, the end rings of the left and right ring nets are rotatably connected one after another by the bent part CWa of the wire CW of a predetermined length, as if sewn together, and a wide ring is formed. Net,
Alternatively, a bag-shaped ring net can be obtained.

In this example, the case where the ends of the ring nets arranged in a staggered manner are connected was explained, but in the case where the ring nets are arranged in a straight line vertically and horizontally as described above, the ring nets are transferred intermittently at the pitch of the rings. , pallet transfer direction center line C
It is only necessary that the axes PC of the press rod and the die holder coincide with each other on the LI, and that the press tip and the die plate face each other perpendicularly to the center line in the pallet transfer direction. In this case, the ring connecting device is connected to the press rod Also, a device for shifting and rotating the die holder can be omitted, and the press rod and the die holder only need to move toward and away from each other in synchronization.
