Systems, apparatus and methods for rotating a container in a container manipulation system
Methods and apparatus for rotating a container delivered to a container manipulation system on a conveyor are described. In some embodiments, first and second carriages are positioned on opposite sides of the conveyor, each carrying respective forward and rear clamp arms. Each clamp arm is selectively independently moveable and carries at least first and second vertically spaced-apart wheels. All of the wheels are engageable with the container on the conveyor. At least two wheels on the first carriage are power-driven and selectively rotatable. The remaining wheels are free-spinning. Additional methods, systems and apparatus are also disclosed.
1. Apparatus for rotating a container in a container manipulation system, the container being delivered to the container manipulation system on a conveyor, the conveyor having first and second sides and front and rear ends, the apparatus comprising:
first and second carriages being positioned proximate to opposite sides of the conveyor, respectively, whereby the first carriage is closer to the first side of the conveyor and the second carriage is closer to the second side of the conveyor,
each carriage carrying respective forward and rear clamps arms, the rear clamp arm of each carriage being closer to the rear end of the conveyor than the respective associated front clamp arm, and
each clamp arm being selectively independently moveable toward and away from the container on the conveyor and carrying at least first and second vertically spaced-apart wheels, whereby the wheels on the respective rear clamp arms are rearward of the wheels on the corresponding associated front clamp arms relative to the conveyor, wherein all of the wheels are engageable with the container on the conveyor, at least two of the wheels on the first carriage are power-driven and selectively rotatable and the remaining wheels on the first and second carriages are free-spinning.
