Abstract
An orbital stretch wrapping apparatus is provided and includes a base frame, a circular ring mounted on the base frame and rotatable with respect to the base frame about an axis of rotation, a stretch film dispenser mounted on the circular ring and rotatable with the circular ring about the axis of rotation, the stretch film dispenser having a subframe fixed to the circular ring, a roll of stretch film mounted to the subframe and rotatable with respect to the subframe, a first feed roller mounted to the subframe and rotatable with respect to the subframe, a second feed roller mounted to the subframe and rotatable with respect to the subframe, and a brake member connected to the first feed roller and the second feed roller.
Claims11
An orbital stretch wrapping apparatus, comprising:
- a base frame;
- a circular ring mounted on the base frame and rotatable with respect to the base frame about an axis of rotation;
- a stretch film dispenser:
- (a) mounted on the circular ring,
- (b) rotatable with the circular ring about the axis of rotation, and
- (c) having:
- (1) a subframe fixed to the circular ring, and
- (2) a roll of stretch film:
- (i) mounted to the subframe,
- (ii) rotatable with respect to the subframe, and
- (iii) being a continuous piece of the stretch film,
- (d) a first feed roller:
- (1) mounted to the subframe,
- (2) rotatable with respect to the subframe,
- (3) engaging the stretch film of the roll of stretch film, and
- (4) rotating at a roller speed during rotation of the circular ring at a set speed,
- (d) a second feed roller:
- (1) mounted to the subframe,
- (2) rotatable with respect to the subframe,
- (3) engaging the stretch film of the roll of stretch film, and
- (4) rotating at the roller speed during rotation of the circular ring at the set speed;
- and
- a brake member:
- (a) connected to the first feed roller and the second feed roller,
- (b) capable of adjusting the roller speed while the circular ring rotates at the set speed,
- (c) having a braking disc pressed with a varying force against a rotor portion of the first feed roller to adjust the roller speed, and
- (d) having a spring housing containing a compression spring disposed on a pair of guide pins attached to the braking disc biasing the braking disc against the rotor portion.
