Abstract

Conventionally, substrate carrying trays having tracks therein which contain substrates for feeding purposes, are maintained in a tray unloader and are indexed into position, so as to permit unloading of the vertically oriented tracks in the tray into machines for subsequent work, other trays or holders for the substrates. Frequently the trays or substrates tend to hang-up effecting operational downtime, while the operator manually removes the trays and releases the substrate or corrects the jam. In order to avoid the necessity of removing some or all of the trays from the unloader to correct a jam in one of the trays, the latch hinge arrangement illustrated is provided.

Hinge Latch for Component Tray Unloaders

Conventionally, substrate carrying trays having tracks therein which contain substrates for feeding purposes, are maintained in a tray unloader and are indexed into position, so as to permit unloading of the vertically oriented tracks in the tray into machines for subsequent work, other trays or holders for the substrates. Frequently the trays or substrates tend to hang-up effecting operational downtime, while the operator manually removes the trays and releases the substrate or corrects the jam. In order to avoid the necessity of removing some or all of the trays from the unloader to correct a jam in one of the trays, the latch hinge arrangement illustrated is provided.

The tray holder 10 includes a hingeably mounted latch assembly 11 having a depending flange 12 spaced from the body of the loader, so as to define a passageway 13 for the receipt of substrate trays 14 therein. The trays 14 are indexed into and out of the plane of the paper. The latch is pivotally mounted on a pair of hinge pins 15, which are fixed at their ends to the base 20 connected to the loader 10. The base 20 includes a recess, hole or flat 16 on one surface thereof which is engageable by a spring loaded plunger 17, which locks the latch into the position shown is the drawing, and which permits engagement of the inner edge of a piston 18 (also spring loaded as by the spring 18A) against a leaf spring 19 in the substrate tray 14. (The leaf spring 19,...
