ABSTRACT:
A re-taping machine for re-packaging radial lead capacitors. The capacitors arrive taped to discrete strips, with gaps at some positions where defective capacitors have been removed. The machine advances the discrete strips through a capacitor removal station. There a single puller tool is reciprocated to remove successive capacitors by pulling them laterally free of the tape and strip. The puller tool is readily removable and replaceable by other puller tools adapted for different types of capacitors. The tool has a claw which enters the space between the radial leads and engages positively against either the head of the capacitor or against kinks formed in the leads. The tool is also formed with a capacitor restraining bar which rests against the leads to control the fall of the capacitor onto a continuous output strip which serves as the new packaging medium. The puller tool drive linkage includes means for lowering and raising the tool while simultaneously rotating it first to insert the claw and later to extract it. There are also additional capacitor restraining blades which engage from above and below to control the fall of the capacitor onto the output strip. Sensing means detect when a capacitor is in position for removal, and then activate the puller tool. Other sensing means detect when the removed capacitor has been deposited upon the output strip, and then activate an indexing wheel which advances the output strip. The indexing wheel has two flanges which couple positively to the capacitor leads on both sides of the output strip. As the capacitors are advanced, a guide shoe takes over the capacitor restraining function before the capacitors get out of range of one of the restraining tongues. A re-taping wheel is positively coupled to the indexing wheel, and applies a new strip of adhesive tape to secure the capacitors to the output strip. Sprocket holes are punched in the output strip, and mesh with a sprocket drive wheel. After that is accomplished, the capacitor leads are trimmed off on one side of the output strip, since they are no longer needed for drive purposes. Then the output strip is reeled up, to be ready for use as a continuous input to an automatic printed circuit component insertion machine.
