It is fixed to. In the illustrated example, 36 index positions in the index table 1 are sequentially set to 1
If H-36H, 1H, 11H-19H, 25H-
The processing machines 3 located at 28H, 30H, 32H to 36H belong to the first group G1, and the processing machines 3 located at 2H to 10H belong to the second group G2, 20H to 24H,
The processing machines 3 located at 29H and 31H are in the third group G
It is 3. The mounting tables 48, 48 to which the processing machines 3 located at the index positions 29H and 31H in the third group G3 are fixed are different from each other, and the mounting tables 48 to which the processing machines 3 located at the index positions 20H to 24H are fixed. The base 48 is also different, and for this purpose the third group G3 is provided with three mounting bases 48, each of which has the same plate 4
0 is fixed on a horizontal plate 46, and the same vertical movement is performed for this purpose.

The processing machines 3 arranged at the index positions 1H to 36H are respectively responsible for the next processing. In addition, a blank space is an empty position where the processing machine 3 is not installed. 1H (G1) Lead wire insertion fixed size cut 2H (G2) 3H (G2) V-shaped shaping between two lead wires 4H (G2) Narrow lead wire and insert bead 5H (G2) V-shaped spread between two lead wires 6H ( G2) Crush the lead wire tip 7H (G2) L-shaped lead wire tip 8H (G2) V-shaped lead wire tip 9H (G2) V-shaped spread between two lead wires / bead presence check 10H (G2) 11H (G1) Bead heating 12H (G1) Bead heating and melting 13H (G1) Bead heating and melting 14H (G1) Shaped between two lead wires into a morning glory 15H (G1) Bead heating and melting 16H (G1) Lead wire foot bending correction 17H (G1) Lead wire Foot bending correction 18H (G1) Lead wire bending correction 19H (G1) Insert two anchors into the bead 20H (G3) Anchor tilt shaping 21H ( 3) 22H (G3) Anchor tip bending correction 23H (G3) Anchor tip hook forming 24H (G3) Anchor tip secondary forming 25H (G1) Lead anchor heating hydrogen reduction (oxide removal) 26H (G1) Lead anchor heating Hydrogen reduction (oxide removal) 27H (G1) Filament coil lead wire clinch 28H (G1) 29H (G3) Filament coil anchor hook 30H (G1) Narrow lead wire 31H (G3) Filament coil anchor hook shaping 32H (G1) Filament coil continuity check 33H (G1) Splice shape image inspection 34H (G1) Bead mount take-out transfer 35H (G1) 36H (G1) Mount take-out mistake discharge Two of the two held by the chuck 2 at the index position 1H. Lead wire As the index position is sequentially changed by the rotation of the index table 1, the above-described processing is performed in order. As is clear from the processing content and the grouping, the processing machines 3 belonging to the second group G2 The processing machine 3 mainly belonging to the third group G3 mainly performs machining on the leading end of the lead wire, and the machining machine 3 mainly belonging to the leading end of the anchor. The processing on the base side of the wire and the processing on the beads placed on the chuck 2 are performed.

Therefore, of the height adjustment of the processing machine 3 when the type is changed, the above-described change in the lead wire height h1 has the mounting table 48 on which the processing machine 3 belonging to the second group G2 is mounted. The change of the anchor height h2 can be performed collectively by operating one of the up-and-down movement units 4, and the change in the anchor height h2 has the mounting table 48 to which the processing machine 3 belonging to the third group G3 is mounted. Activating the vertical movement unit 4 can be performed collectively. It is not necessary to adjust the height for each individual processing machine 3, and the remote control of the servomotors 41, 41 of the vertically moving units 4, 4 by the control means for controlling this manufacturing apparatus makes it necessary. The adjustment amount can be adjusted. In addition, since the height relationship between the processing machines 3 performing the processing on the leading end of the lead wire or the height relation between the processing machines 3 performing the processing on the distal end of the anchor is kept constant, the processing is performed. There is no possibility that the balance between the machines 3 is lost.

Although the manufacturing apparatus in the bead mount making step has been described, the present invention can also be applied to manufacturing apparatuses such as a bead mount attaching step to a valve, a valve neck processing and valve sealing step, and an inspection step. Of course. All machines located at the index position are grouped into those that require the same amount of height adjustment and those that do not require height adjustment, and a height adjustment is required by providing a mounting base for each group. The height of the mounts of the groups can be adjusted, in particular, the height can be adjusted by remote control, so that the height can be adjusted collectively for each group. Further, in the above-described embodiment, two types of mounting bases that can be adjusted in height are provided so as to correspond to two types of height adjustment amounts. Needless to say, only one mounting base is required, and when the height adjustment amount is three or more, three or more mounting bases with adjustable height are also provided. Furthermore,
The height adjustment amount is the same for a certain product type, but a different type of processing machine having a different height adjustment value for another product type can be used for many product types by installing them on different mounts. Although the height of the mounting base 12 in the example of the above embodiment cannot be adjusted, the height of the mounting base 12 may be freely adjustable.

[0016]

As described above, in the present invention, the mounting base on which each processing machine is installed is divided into a plurality of parts, and the height of some or all of the mounting bases can be adjusted individually to switch the manufacturing type. Machines that require height adjustments are installed on different mounting bases due to differences in height adjustment amount.Therefore, when changing manufacturing types, install machines that have the same height adjustment amount. The height can be adjusted in a lump by adjusting the height of the table, and it is not necessary to adjust the height for each processing machine, and the positional relationship between processing machines with the same height adjustment amount. It is possible to significantly reduce the time required for height adjustment at the time of product type change without causing any deviation.

If the height-adjustable mount is adjusted by a vertically controllable vertical movement unit,
Since it is not necessary to perform the adjustment operation while measuring the height adjustment amount when changing the product type, the operation is further facilitated and the situation where the adjustment is performed with an incorrect adjustment amount does not occur.
