Abstract

An interlock mechanism prevents an operator from opening the tape reel loader while the tape from the reel is threaded through the drive mechanism. The interlock mechanism is actuated by the threading mechanism of the drive to pivot an interlock mechanism that prevents the opening of the loader. The mechanism is held in the two positions by an over-center toggle spring. Fig. 1 shows the top view of the latch interlock mechanism. The mechanism is shown in the latched or interlocked position. The latch 1 is offset from its crank arm 2, which is, in turn, journaled at pivot point 3 to the drive housing 4. Fig. 2 shows the offset position of the latch 1 from its crank arm 2. An L-shaped arm 5 interfaces with a pin 6, mounted on one end of the crank arm 2, to pivot the crank arm 2 around its pivot point 3.

Tape Reel Loader Latch Interlock

An interlock mechanism prevents an operator from opening the tape reel loader while the tape from the reel is threaded through the drive mechanism. The interlock mechanism is actuated by the threading mechanism of the drive to pivot an interlock mechanism that prevents the opening of the loader. The mechanism is held in the two positions by an over-center toggle spring. Fig. 1 shows the top view of the latch interlock mechanism. The mechanism is shown in the latched or interlocked position. The latch 1 is offset from its crank arm 2, which is, in turn, journaled at pivot point 3 to the drive housing 4. Fig. 2 shows the offset position of the latch 1 from its crank arm 2. An L-shaped arm 5 interfaces with a pin 6, mounted on one end of the crank arm 2, to pivot the crank arm 2 around its pivot point 3. The L-shaped arm 5 is pivoted at point 7. At the other end of the L- shaped arm 5 is mounted a receiver 8 that is shaped to collect the threading mechanism shown at reference numeral 9. A toggle spring (not shown for clarity) is mounted between pins 10 and 11. Pin 11 is mounted to one end of the crank arm 2, while pin 10 is mounted to the drive housing 4. The latch 1 interferes with a tongue 12 to accomplish the interlock that prevents the loader from being open. In operation, to remove the latch 1 from interlocking with the tongue 12 of the loader, the threading mechanism 9 interfaces with the receiver 8 to pivot the L- shaped arm 5...
