BRIEF SUMMARY
BACKGROUND OF THE INVENTION

The invention is directed to a delivery means for delivering electrical components to an automatic equipping unit for equipping electrical printed circuit boards.
Such a delivery means has been disclosed, for example, by EP 0 599 319 B1. In accord therewith, the delivery means comprises a magazine for reels with component part belts, whereby the reels can be joined to one another in a stack-like configuration in axial direction. The reels are individually held at sheet-like flat parts that are seated at the delivery means pivotable around a swiveling axis. The flat parts have their bearing location provided with a slot-like recess into which the swiveling axis engages. In the proximity of the swiveling axis, the delivery means comprises comb-like guide plates for the flat parts that are provided with lateral guide slots. A further comb-like guide part is arranged on the other end of the flat parts, so that these can be laterally held at two locations.
The invention is based on the object of structurally simplifying the delivery means and simplifying the operation thereof.


SUMMARY OF THE INVENTION

In general terms the present invention is a delivery means for delivery of electrical components to an automatic equipping unit for equipping electrical printed circuit boards. The delivery means is provided with a magazine for reels with component belts. The reels adjoin one another in an axial direction. The reels are individually held at sheet-metal-like flat parts that are seated swivellable around a swiveling axis at the delivery means. The flat parts are fashioned fork-like at their bearing location and are provided with a slot-like recess into which the swiveling axis engages. The delivery means is provided with lateral guide slots in the proximity of the swiveling axis, the flat parts projecting ant heir function position into the lateral guide slots. The guide slots are fashioned between guide disks that have a central bore slipped onto the swiveling axis and that are placed adjoining one another. The ring-like spacer elements, whose thickness is at least equal to the thickness of the flat parts, are arranged between the guide disks. The width of the recess is greater than the diameter of the spacer elements.
The preferably circular guide disks can be plugged onto the swiveling axis in alternating sequence with the spacer elements and can be secured between lateral supports of the swiveling axis. The spacer elements can, for example, be fashioned as separate spacer disks or can be connected of one piece to the guide disks. A guide length for the flat parts having the approximate diameter of the guide disks derives between the spacer disks. This guide length suffices in order to forego additional guides, for example at the other end of the flat parts.
After being plugged in, the flat parts are adequately guided in every swivelled attitude. For replacing reels, individual flat parts together with the reels can be swivelled out of their haul-off position broad-angled and can be subsequently swivelled back in without a threading procedure.
In an advantageous development of the present invention the flat parts project at least slightly beyond the reels and, proceeding from the center axis of the reel, are fashioned proceeding outwardly bent off opposite the haul-off direction of the belts.
As a result the free ends of the flat parts can remain outside the belt haul-off plane and are easily accessible for the purpose of being swivelled out.
