1,274,899. Assembly apparatus. SWANSON-ERIE CORP. 14 Nov., 1969 [14 Nov., 1968], No. 55889/69. Heading B3A. A machine for assembling parts of articles comprises a support member 60, a vertical column 37 supported thereby, a plate 17 and index table 10 on the column and means to cause relative oscillation and reciprocation between the column and plate 17 to move a first article part on the table 10 and a second article part on the plate towards each other for assembly with each other. The first article parts are fed from vibratory bowl feeders (40, 41), Fig. 4 (not shown) through tracks (42, 43) into chambers (44) on the table 10. The second article parts are fed by means 45 to a fixed plate 12, from which they are picked up by placement heads (14) on the plate 17, Fig. 5 (not shown). As a camshaft 19 rotates, a cam 69 reciprocates a shaft 62 which is attached to the plate 17 by a spider 75. A further cam 84 engages a follower 83, which actuates a linkage 78, 85 to oscillate the shaft 62. The movement of the plate 17 transfers the second parts to the chambers (44), where they are assembled to the first parts. Each time a part is fed to a chamber 44 or an article is assembled, the table 10 is indexed either to receive further parts or for a further assembly operation to occur. |
