Functional Description - TE Connectivity Basic AMP-O-LECTRIC K 1-471273-3 Customer's Manual

vertical reel bracket assembly. The electrical system consists of a main power switch, work lamp, and panel light
located on the left front of the machine; a trip control box assembly inside the back cover; a foot switch; and
electrical wiring. The motor is bolted to a mounting plate that is hinged to the machine frame by a support pin.
The weight of the motor provides enough tension to the V-belt for driving the flywheel.
The basic machine does not contain a ram or base mount. These are supplied with the applicator or the
conversion kit. The ram is mounted behind the ram retaining plate on the front of the frame.
The frame contains holes for bolting the machine to a bench at a height convenient for the operator as described
in Section 3.

2.2. Functional Description

The motor-flywheel assembly runs continuously when the control switch is "on." The flywheel turns on the main
shaft of the transmission until the foot switch is depressed to actuate the solenoid on the transmission. The
energized solenoid pulls up the stop bar (see Figure 3) to release the clutch dog (sliding key), which is then
forced toward the flywheel by spring pressure. The end of the clutch dog then slides into the first opening it
encounters in the drive plate on the rotating flywheel. This connects the rotating flywheel and the drive shaft to
start the machine cycle.
At approximately 270° in the rotation cycle, the beveled forward edge of the notch in the clutch dog encounters
the dog wedge ramp on the face of the dog retainer support. As the clutch dog slides up this ramp against spring
pressure, it is withdrawn from the flywheel drive plate.

During the cycle, the cam on the rear face of the stop collar rides over the pin on the rear finger of the stop bar,
forcing it down to retain the clutch dog in the rest position at the end of the cycle. This brings the end of the front
finger of the stop bar in position to contact one side of the lobe on the front of the stop collar to prevent further
forward rotation of the drive shaft. At the same time, spring tension forces the backup latch in against the
opposite side of the lobe on the stop collar to prevent reverse rotation.
An eccentric arm is keyed to the forward end of the main shaft (see Figure 9). The arm is at TOP-DEAD-
CENTER when the machine is in the rest position. Attached to the arm is a spherical bearing link that actuates
the toggle lever subassembly.
