System for transferring objects
View Patent ↗A system for transporting an object between stations, for example, from a magazine to a conveyor is provided having a rotary apparatus having two arms, wherein a first arm rocks back and forth between two positions and a second arm rotates about an axis on the first arm. The second arm can be fixedly connected to a holder having one or more suction heads for grasping the object. Preferably, the holder is arranged parallel to the object and moved in a direction perpendicular to the plane of the object as the object is removed from the magazine. Additionally, the holder is preferably displaced above the conveyor and positioned to be parallel to the conveyor, after which the holder is moved toward the conveyor in a path that is perpendicular to the plane of the conveyor. Therefore, the lateral force, shearing force, and friction exerted on the object during removal from the magazine and deposition onto the conveyor can be minimized.
1. A system for transporting an object, the system comprising:
at least two holders, each holder constructed and arranged to selectively grasp, retain, and release an object having an object plane, wherein
each holder defines a path from a source to a destination having a receiving surface,
wherein the path includes a first straight portion as the object is removed from the source, the first straight portion extending perpendicularly to the object plane, and a second straight portion as the object is released onto the receiving surface, the second straight portion crossing the receiving surface;
each holder is constructed and arranged to selectively release the object onto the receiving surface when the holder is on the same level as the receiving surface and the holder is capable of descending under the receiving surface after releasing the object; and
a mover constructed and arranged to move the at least two holders, wherein the mover includes a first arm rotatable about a first axis and at least one second arm rotatable about a second axis, wherein
the at least one second arm is attached to at least one of the at least two holders extending in opposite directions from the second axis.
2. The system of claim 1 , wherein each holder rotates about the first axis and the second axis.
3. The system of claim 1 , wherein the first straight portion of the path is defined by the rotation of each holder about the first axis.
4. The system of claim 1 , wherein a second straight portion of the path is defined by the rotation of each holder about the first axis.
5. The system of claim 1 , wherein the second axis is located a distance from the first axis.
6. The system of claim 1 , wherein each second arm is rotatable by at least 360 degrees about the second axis.
7. The system of claim 1 , wherein the first arm pivots back and forth between two positions.
8. The system of claim 1 , wherein the first arm and each second arm is controlled independently of each other.
9. The system of claim 1 , wherein the at least one second arm is pivotally connected to the first arm.
