Abstract
A transfer arm includes a magnet which can be placed in alignment with the spindle aperture of a recording disc. A spindle is mounted to a support at a stacking station for receiving the aperture of the disc on the transfer arm when the disc is released. The extended tip of the spindle includes a swivel member made of magnetic material which is placed in alignment with the disc aperture by the magnetic field produced by the magnet. The disc is then released from the arm at the stacking station and slips over the aligned swivel tip onto the spindle for stacking.
Claims11
An article transfer apparatus comprising:
- article transfer means for carrying an article to a receiving station,
- means secured to said transfer means for producing a magnetic field,
- means for releaseably securing an apertured article to said transfer means,
- means for placing the article aperture in said field,
- article receiving means at said station including aperture receiving means, and
- a tiltable member of magnetic material on said aperture receiving means and positioned to be placed in said field when the carried article is at said station thereby tilting said member into alignment with said carried article aperture.
Apparatus including article transfer means for releaseably securing an apertured article thereto and for placing said article on a receiving member at a receiving station, said receiving member including a rod for insertion in the article aperture during the receiving, said rod tending to be misaligned with said aperture during said receiving, the improvement wherein said transfer means includes magnet means and means for aligning the field of said magnet means with the article aperture, and a moveable tip secured to the end of the rod and made of magnetic material, said tip being responsive to said magnetic field so that the tip moves in alignment with said aperture when in said field, said tip being located on said rod so it is in said field when said transfer means is at said receiving station.
In a system for stacking records, each with a central aperture, at a stacking station with a vertical spindle thereat, by moving the record by means of a transfer arm until the record is in position over the stacking station with the aperture therein aligned with the spindle and then dropping the record so that it slides down the spindle, an improved arrangement for insuring that the spindle end is aligned with the aperture in the record before the record is dropped comprising:
- the spindle including an end portion which is formed of magnetic material and which is loosely joined to the remainder of the spindle so that it can be moved to different positions;
- and
- magnet means on the transfer arm for producing a magnetic field within which the aperture in a record is centered, when said record is moved into position over the stacking station, for causing said end portion of the spindle to align with the aperture before the record is dropped.
