Here, the punch rod 58 has a flange portion 58a formed near its base end, and is urged to move toward the distal end by a coil spring 59 interposed between the flange portion 58a and the support hole 57b. , and the flange portion 58a is connected to the support hole 57b.
By coming into contact with a stepped portion 57c formed in , movement due to the biasing force of the coil spring 49 is prevented. When the second slide body 38 configured as described above moves forward toward the locking portion 22 of the supply device B, the punch rod 58 is attached to the hook lid body that is locked to the locking portion 22. The second crushing piece 57 resists the urging force of the abutting coil spring 59 and sinks into the second crushing piece 57, and the second crushing piece 57 abuts on the hook lid body, and the first crushing piece 57 provided on the first slide body
The punch rod 58 cooperates with the second crushing piece 48 to crush the peripheral edge of the hook lid body to join the hook lid body and the hook body together, and when the punch rod 58 moves back, the second crushing piece 48 collapses due to the biasing force of the coil spring 59. The hook lid body engaged with 57 is pushed out. Here, the first slide body 37 and the second slide body 38 and the first and second cylindrical cams 5 and 6 described above are
constitutes a bonding device main body C.

Further, FIGS. 9 and 10 respectively show examples of a hook lid body 60 and a hook body 61 that are joined using the above-mentioned hook joining apparatus A. As shown in FIG. 9, the hook lid body 60 has a short cylindrical shape with a bottom and includes a disk-shaped substrate 60a and a peripheral wall 60b, and the hook body 61 has a substrate 61a as shown in FIG. An engaging protrusion 61b is provided at the center. The hook lid body 60 and the hook body 61 are
The hook body 61 is inserted into the hook lid body 60, and the peripheral wall 60b of the hook lid body 60 is caulked inward to be joined together.

Next, the operation of the apparatus configured as described above will be explained.

In this hook welding device A, the supply device B and the welding device main body C operate simultaneously by starting the drive device and rotating the rotating shaft 1. here,
First, in the case of the supply device B, the rotation of the first and second plate cams 3 and 4 causes the first and second sliding bodies 15 and 1 to
6 reciprocates in a direction perpendicular to the axis of the rotating shaft 1. The first and second sliding bodies 15,
16 slides toward the locking part 22 provided between them, the first and second transfer passages 21, 2
The hook lid body 60 and the hook body 61 transferred from 6 are transferred to the first and second sliding bodies 15 and 1, respectively.
6 at the same time to the locking portion 22, and in the locking portion 22, the locking pieces 31 and 32 are positioned behind the locking pieces 31 and 32 in FIG. ). At this time, the hook lid body 60 and the hook body 61 are rotated at the locking portion 22 because the first and second sliding bodies 15 and 16 are provided shifted by a predetermined distance in the axial direction of the rotating shaft 1. They are in an overlapping state along the axial direction of the shaft 1.

On the other hand, in the case of the bonding device main body C, the first and second
By rotating the cylindrical cams 5 and 6, the first,
The second slide bodies 37 and 38 reciprocate in the axial direction of the rotating shaft 1 with a predetermined motion. Here, the first and second slide bodies 37 and 38 are attached to the hook lid body 60 on the locking part 22 in the supply device B described above.
Almost at the same time as the hook body 61 is fed, it begins to advance toward the locking portion 22. and,
First, the hook body presser bar 47 provided on the first slide body 37 and the punch bar 58 provided on the second slide body 38 enter the through hole 30 of the locking portion 22, and the hook body presser bar 47 On the hook 61,
The punch rods 58 abut the hook lids 60 at the same time, and hold the substrate 61a of the hook body 61 in contact with the substrate 60a of the hook lid 60.
Further, as the first and second slide bodies 37 and 38 move forward, the hook body presser bar 47 and the punch bar 58 move to the first position against the biasing force of the coil springs 49 and 59 that bias their respective movements. , respectively retreat into the second crushing pieces 48 and 57, and the first crushing piece 48 pushes up and down the locking pieces 31 and 32 of the locking part 22, respectively, and enters the through hole 30 to close the lid. At the same time, the second crushing piece 57 is pressed to the edge of the peripheral wall 60b of the hook lid 60, and the second crushing piece 57 is pressed to the base plate 60c of the hook lid 60, so that the peripheral wall 60 of the hook lid 60 is pressed.
Caulk b toward the inner circumference. In this state, the hook lid body 60 and the hook body 61 are joined together. Then, the first and second slide bodies 3
7 and 38 are locking pieces 31 and 32 in a state where the hook cover body 60 and the hook body 61 which are integrally joined are crimped together.
The hook cover 60 and the hook 61 are conveyed out of the through hole 30 by moving toward the first slide body 37, and then the second slide body 38 retreats.
After the hook body presser bar 47 is separated from the hook body 61, the punch bar 58 is pushed into the engagement recess 57a of the second crushing piece 57 by the biasing force of the coil spring 59.
The hook lid body 60 and the hook body 61, which are integrally joined, are pushed out from the engaging recess 57a.

The above-described operations of the supply device B and the welding device main body C are performed every time the rotating shaft 1 rotates once.

In addition, the first and second crushing pieces 48, 57 and the hook body presser bar 4 in the hook joining device A
7 can be replaced depending on the shape of the hook lid body and the hook body to be joined together. Further, in the above embodiment, the action of joining the hook lid and the hook body together was performed in the through hole of the locking part, but the hook lid and the hook body were connected to the second crushing piece. Alternatively, the material may be conveyed outside the through hole while being held between the body presser rods, and the joining operation may be performed outside the through hole. Further, although the above-mentioned hook body presser bar is formed in a shape in which the part that abuts the engagement protrusion of the hook body protrudes, the shape is not limited to this, and a locking hole corresponding to the above-mentioned engagement protrusion may be formed. good.

[Effect of idea]

As described above, the hook joining device according to this invention includes first and second plate cams and first and second cylindrical cams on a rotating shaft rotated by a drive device, and also includes a rotary shaft in the vicinity of the rotating shaft. a locking portion for simultaneously locking the hook lid body and the hook body in the axial direction of the rotating shaft; The second sliding body is configured to slide in a direction perpendicular to the axis of the rotating shaft by the rotation of the first and second plate cams, and is further engaged with the locking portion at the locking portion. A configuration in which first and second slide bodies each having first and second crushing pieces for integrally joining the hook lid body and the hook body by pressure bonding from the front and back thereof are slid by the rotation of the cylindrical cam. Therefore, the entire device can be operated by rotating the single rotating shaft. For this reason, there is no need for a complicated control device that controls the operation timing of the hook lid and the member that supplies the hook body, and the member that joins the supplied hook lid and the hook body together. can be obtained at a low cost, maintenance and adjustment of the device can be performed easily, and when the operation speed is increased because the hook cover body and the hook body are supplied by two sliding bodies. This method also has advantages such as being able to reliably supply and join the hook cover and the hook body.
