2 is moved from the rearward retracted position shown by the solid line in FIG. 11 to the working position in the wire rod tension member 59 shown by the chain line, and as shown in FIG. 4 and FIG. Of the adhesive Ad. In this state, the adhesive Ad on the work W is irradiated with ultraviolet rays from the lamp body 132 via the irradiation rods 134, and the adhesive Ad is cured.

Next, the operation of the wire sticking device constructed as described above will be described with reference to the timing chart shown in FIG. By the way, during operation of this device, the intermediate shaft 105 moves to 1 when the motor 104 of the drive mechanism 103 is started.
After the rotation, the motor 104 is stopped for a predetermined time, and by repeating this cycle, the wire sticking mechanism 10
Intermittent rotation of the wire rod tension member 59 in the
And the separation movement of the moving mechanism 90 are performed in synchronization. That is, first, when the motor 104 is stopped,
The conveyer 3 is arranged at the upper position shown by the solid line in FIG. Then, in this state, the work W is carried in from the carry-in conveyor 4 onto the carry conveyor 3 by the carry-in mechanism 8 and the carry-out conveyor 3 is carried out by the carry-out mechanism 13.
The work W after processing is carried out from the carrying-out conveyor 6.

When the motor 104 starts rotating,
The intermediate shaft 105 shown in FIGS. 8 and 9 is rotated and the cam plate 1 is rotated.
The cam mechanism of the cam groove 120a of the moving mechanism 90
The transporting conveyor 3 is gradually moved down to the lower position shown by the chain line in FIG. The conveyer 3 is started to move upward before the intermediate shaft 105 completes one rotation, and is arranged at the upper position when the intermediate shaft 105 completes one rotation.

Further, with the rotation of the intermediate shaft 105, the rotary shaft 58 is rotated via the master wheel 109 and the slave wheel 110 of the Geneva gear mechanism, and the wire rod tension member 59 is rotated 90 degrees. This rotation of the wire rod tension member 59 is performed while the drive pin 109a of the original vehicle 109 is engaged with the engagement groove 110a of the driven vehicle 110, that is, as shown in FIGS.
The rotation angle of 05 is performed between 0 degree and almost 110 degrees.
Further, as the rotary shaft 58 rotates, the first transmission shaft 111
And the transfer conveyor 3 via the second transmission shaft 114 and the like.
Is transported and rotated. The rotation of the conveyer 3 is performed while the wire rod tension member 59 is rotated 90 degrees, that is, the intermediate shaft 1 is rotated.
The rotation angle of 05 is performed between 0 degrees and approximately 110 degrees, whereby the work W is conveyed rightward by one pitch P shown in FIG.

Further, when the work W carried in on the carrying conveyor 3 is carried by one pitch P and is carried to a position corresponding to the adhesive applying mechanism 9, the work is transferred from the adhesive applying mechanism 9 to the work. Adhesive Ad is applied to a plurality of wire rod attachment points on W. The application operation of the adhesive Ad is the same as the loading / unloading operation of the work W described above.
04 is stopped and the conveyor 3 is placed in the upper position shown by the solid line in FIG.

On the other hand, the wire rod tension member 59 of the wire rod tensioning mechanism 10 is rotated by 90 degrees so that the chuck members 62 located on the upper left and right sides of the wire rod tension member 59 move up and down on the left side (arrows L1 and L2 in FIG. 4). 4), the upper and lower chuck bodies 62 on the left side are arranged at the gripping position by the cam action of the first cam 73, as is apparent from FIG. Thereby, the plurality of wire rods W supplied from the wire rod supply mechanism 11
The Rs are gripped between the upper and lower chuck bodies 62, and are arranged in parallel along the left side of the wire rod extending body 59.

Further, as the wire rod tension member 59 is rotated by 90 degrees, the chuck members 62 located above and below the left side of the wire rod tension member 59 are rotationally moved to the lower left and right (positions of arrows U1 and U2 in FIG. 4). When this is done, each chuck body 62 is continuously held at the gripping position, and the gripping state of the wire rod WR by the chuck bodies 62 on the lower left and right sides thereof is maintained. The gripping of the wire rod WR by each of the chuck bodies 62 moved leftward and rightward is released when the wire rod tension member 59 starts to rotate in the next cycle.

Further, when the wire rod tension member 59 is rotated by 90 degrees, the cam action of the second cam 83 causes the wire rod tension member 59 to be positioned at the lower left 45 degree position as shown in FIG. The cutter 82 is advanced from the retracted position on the center side of the wire rod tension member 59 to the cutting position. This allows
A wire rod WR that is lapped around the lower side of the wire rod tension member 59.
At the lower left corner of the wire rod tension member 59, it is cut from the portion that is lapped around the left side.

When the intermediate shaft 105 is rotated once to move the conveyor 3 to the upper position, the conveyor 3 has been conveyed by one pitch P from the position corresponding to the adhesive applying mechanism 9. The work W on the conveyor 3 is arranged near the wire rod extending body 59 at the wire rod attaching position ST. Then, the plurality of wire rods WR in a state of being gripped by the lower side of the wire rod tension member 59 and cut from the portion that is circularly gripped by the left side thereof are arranged correspondingly on the plurality of pairs of adhesives Ad of the work W. It is stuck and stuck.

As is apparent from FIG. 12, when the conveyer 3 is moved upward, the convey rotation of the conveyer 3 is already completed. Therefore, the transport conveyor 3
The upper work W is lifted in the vertical direction and is arranged close to the wire rod tension member 59 without being transported by the conveyor 3. For this reason, the work W does not come into contact with the wire rod WR on the wire rod extended body 59 from an oblique direction, and there is no possibility that the work W is displaced with respect to the wire rod extended body 59.

Thus, the motor 104 drives the intermediate shaft 1
While 05 is rotated once, the work W is transported by the transport conveyor 3, the transport conveyor 3 is moved up and down, and the wire rod tension member 59 is stretched.
Rotation, feeding and sticking of the wire WR onto the work W, and cutting of the wire WR. And this motor 104
4 and 11, the lamp main body 132 of the adhesive curing mechanism 12 is in the section where the wire rod tension member 59 is stopped.
The tip of each irradiation rod 134 is brought into contact with the adhesive Ad on the work W by being moved forward to the inner working position. In this state, the adhesive Ad on the work W is irradiated with ultraviolet rays from the lamp body 132 through the irradiation rods 134, and the adhesive Ad is cured.

When the irradiation of the ultraviolet rays by the lamp main body 134 is completed, the lamp main body 132 is moved backward to the rear retracted position shown by the solid line in FIG.
Starts to rotate, and the rotation of the intermediate shaft 105 is restarted. Then, as described above, the wire rod tension member 59 starts to rotate, and the descending movement of the conveyor 3 and the operation of conveying the work W by the conveyor 3 are started. At this time,
The wire rod WR, which is stuck on the adhesive Ad of the work W and is gripped around the lower side of the wire rod tension member 59, is released from being gripped by each chuck body 62 as the wire rod tension member 59 starts rotating. To be done. Moreover, the work W on the conveyor 3 is separated from the wire rod tension member 59 by the downward movement of the conveyor 3. Therefore, the work W on the transfer conveyor 3 after processing is reliably transferred to the position corresponding to the unloading mechanism 13 without interfering with the wire rod tension member 59.

As described above, in the wire rod sticking apparatus of this embodiment, the work W is carried in and out, the plurality of wire rods WR are supplied onto the work W, the sticking, and the wire rods WR.
Can be continuously and automatically cut. Therefore, the work efficiency of attaching the wire WR can be improved, and the productivity can be improved.

Further, in this embodiment, the wire rod tension member 59 having a substantially rectangular cross section is intermittently rotated by 90 degrees, so that the plurality of wire rods WR circulate along one side of the outer periphery of the wire rod tension member 59. The wire rods WR are arranged and supplied onto the work W and attached. For this reason, a plurality of wire rods WR can be supplied onto the work W at one time and easily attached, and the supply and attachment operation can be continuously performed, which greatly contributes to the improvement of work efficiency.

Further, in this embodiment, a plurality of chuck bodies 6 for gripping the wire rod WR on the wire rod extended body 59.

You can stick. Therefore, even when many thin wire rods WR of 1 mm or less are stuck on the work W at narrow intervals of several mm as in the present embodiment, the wire rods WR are cut on the work W while cutting them to a predetermined length. It can be attached easily and accurately, and the attachment does not require time and effort.

Moreover, in this embodiment, the cam members of the first cam 73 and the second cam 83 accompany the intermittent rotation of the wire rod tension member 59, and the chuck member 62 for holding the wire rod 62.
Also, the cutter 82 for cutting the wire rod is operated. Therefore, it is not necessary to provide a separate drive source for operating the chuck body 62 and the cutter 82, and they can be operated while being accurately synchronized with the intermittent rotation of the wire rod tension member 59.

Further, in this embodiment, when the wire rod extended body 59 is rotated intermittently, the conveyor 3 is moved up and down and separated from the wire rod extended body 59. Therefore, when the wire rod tension member 59 having a substantially polygonal cross section is rotated intermittently, it is possible to prevent the wire rod tension member 59 from interfering with the conveyer 3 or the work W.

Further, in this embodiment, one motor 104 of the drive mechanism 103 intermittently rotates the wire rod tension member 59, the transport operation of the transport conveyor 3, and the movement mechanism 90 separates the transport conveyor 3. The movement and the movement are synchronized with each other. For this reason, the structure of the drive mechanism 103 can be simplified, and there is no deviation in the operation timing of them. Moreover, in this embodiment, after the adhesive Ad is applied to the work W by the adhesive applying mechanism 9, the wire rod WR is attached.
At that position, the adhesive curing mechanism 12 irradiates the adhesive Ad on the work W with ultraviolet rays to cure the adhesive Ad. Therefore, the wire W on the work W
