Title:
SHOCK ABSORBING FEED WHEEL ASSEMBLY
Document Type and Number:
WIPO Patent Application WO/2017/209924
Kind Code:
A8
Abstract:
A strapping machine of the type that feeds, retracts, tensions and seals strap to itself to form a loop of strap around a load, has a shock absorbing feed wheel assembly. The machine includes a frame, a feed head having a motor, a tension head, a sealing head and a strap chute mounted to the frame. The feed wheel assembly has a friction engaging surface and at least one pocket formed therein. A spring hub is engaged with the feed wheel and has at least one pocket formed therein corresponding to the feed wheel pocket. The spring hub is operably connected to the feed head motor. At least one spring is positioned in the feed wheel pocket and the spring hub pocket and is sandwiched between the feed wheel and the spring hub. The feed wheel is driven by rotation of the spring hub and engagement of the spring with the feed wheel pocket and spring hub pocket. The shock absorbing feed wheel assembly dampens the forces on the feed head motor and drive when the feed wheel comes to an abrupt stop and prevents strap slippage.
