Method and apparatus for gripping containers
View Patent ↗An apparatus and method for gripping containers, each having a circumference, for dumping material in a material collection vehicle including more than one gripping mechanisms, wherein each of the gripping mechanisms can engage a container around at least one-half of the circumference of the container. In one embodiment, the gripping mechanism is attached to a base member and includes an outer gripping member pivotally attached to the base member and an inner gripping member pivotally attached to the base member and an actuating mechanism for moving at least one gripping member toward the other gripping member.
1. A dual gripping apparatus for gripping two material containers and depositing material in the containers in a collection vehicle, said two containers to be at a separation distance when gripped, said dual gripping apparatus comprising:
a base member
a first outer gripping mechanism, said first outer gripping mechanism having a retracted position and an engaged position;
a first inner gripping mechanism, said first inner gripping mechanism having retracted position and engaged position;
a second inner gripping mechanism, said second inner gripping mechanism having a retracted position and engaged position;
a second outer gripping mechanism, said second outer gripping mechanism having a retracted position and an engaged position;
at least said first and second outer mechanisms being pivotably mounted to said base member;
at least one actuator, said actuator being mounted on said base member and said actuator being operatively engaged with at least one of said outer gripping mechanisms to move said at least one outer gripping mechanism between said retracted position and said engaged position;
wherein the collection vehicle includes a plurality of compartments, wherein material dumped from each of the containers that are engaged by the plurality of gripping mechanisms can be kept separate in individual streams.
2. The apparatus of claim 1 wherein for each of said gripping mechanisms at least one of said inner gripping mechanism or said outer gripping mechanism is pivotably attached to said base member.
3. The apparatus for gripping containers according to claim 1 , wherein a top portion of each of the plurality of gripping mechanisms is in a substantially horizontal plane when the container is engaged.
4. The apparatus for gripping containers according to claim 1 , wherein said actuator includes a cylinder.
5. The apparatus for gripping containers according to claim 1 , wherein the plurality of gripping mechanisms can be selectively operated to engage a container.
6. The apparatus for gripping containers according to claim 1 , wherein at least two of the plurality of gripping mechanisms can be selectively operated simultaneously to engage at least two of the containers.
7. The apparatus of claim 1 where each of said inner and outer gripping mechanisms remain in a substantially horizontal plane in all positions.
