Claims14
A stop for stopping articles that are travelling along a conveyor, comprising:
- a stop arm, defining a bore and including an upper arm portion above the bore and a lower arm portion below the bore;
- a shaft, including an end portion and a cylindrical portion eccentric from said end portion and mounted in said bore, such that said stop arm rotates about said cylindrical portion;
- such that said stop may be moved from an extended position, along an arcuate path, to a retracted position by rotating said shaft.
A stop for stopping articles that are travelling along a conveyor, comprising:
- a stop arm, defining a bore and including an upper arm portion above the bore and a lower arm portion below the bore;
- a shaft, including a cylindrical portion mounted in said bore, such that said stop arm rotates about said cylindrical portion;
- wherein said shaft includes end portions which lie along a single axis which is parallel to and offset from the axis of said cylindrical portion, such that the rotation of said shaft causes said stop arm to move along an arc from an extended position to a retracted position.
A stop for stopping articles moving along a conveyor, comprising:
- a bracket for mounting the stop to the conveyor frame;
- a cam shaft, including coaxial ends and a central cylindrical portion which has an axis that is parallel to and offset from the axis of said ends;
- said bracket defining a bore which receives the ends of said cam shaft;
- and
- a stop arm mounted for rotation about said central cylindrical portion of said cam shaft, said stop arm including an upper portion and a lower portion.
