Abstract

This article describes a variable-width load/unload mechanism for dual- part machines which provides for loading two parts at a time on a machine when the distance between part centers differs from the part hopper to the machine transfer belt. This mechanism is used in conjunction with the automatic insertion of magnetic diskettes into jackets and processing the jackets. A problem exists in loading two parts at a time onto a machine when the distance between part centers differs from the part hopper to the machine transfer belt. The mechanism described herein solves this problem. In the drawings, Fig. 1 is a front view, and Fig. 2 is a top view of the present load/unload mechanism. A pickup-head assembly A has dual-pickup heads tied together by a long steel shaft G with a spring between the two pickup heads.

Variable-Width Load/Unload Mechanism for Dual-Part Machines

This article describes a variable-width load/unload mechanism for dual- part machines which provides for loading two parts at a time on a machine when the distance between part centers differs from the part hopper to the machine transfer belt. This mechanism is used in conjunction with the automatic insertion of magnetic diskettes into jackets and processing the jackets. A problem exists in loading two parts at a time onto a machine when the distance between part centers differs from the part hopper to the machine transfer belt. The mechanism described herein solves this problem. In the drawings, Fig. 1 is a front view, and Fig. 2 is a top view of the present load/unload mechanism. A pickup-head assembly A has dual-pickup heads tied together by a long steel shaft G with a spring between the two pickup heads. The pickup-head assembly is mounted to two linear motion bearing blocks C which slide on a bearing guide D. The righthand bearing block is tied to the rodless air cylinder B by a coupler E. When the pickup-head assembly is open (part centers at widest point), the assembly is in position 2. When the pickup-head assembly is closed, the separating spring is compressed, as is shown in position 1. In operation, when the pickup-head assembly A is to pick parts out of the hopper H (6" centers), the air cylinder drives the coupled pickup-head as far to the left as possible to position 1. This compresses the spring on tie shaft G, closing the center distance of the pickup- heads to six inches. A stop block F provides the mechanical stop for the pickup- head assembly. After picking up parts, the pickup-head assembly moves to position 2. When the coupled pickup head hits the mechanical stop F2, the spring on the shaft G keeps the other pickup head from closing the assembly which provides an 8-inch center distance. The "open centers" distance is determined by the physical length of shaf...
