Abstract
Apparatus for positioning or orienting a hand of tubes, or the like, includes clamp arms for clamping the hand while on a conveyor, a fluid activated ram for raising the hand, inverting it 180.degree., lowering it back onto the conveyor, and releasing the clamp arms. The device may also be tilted while in elevated position so that the clamp arms and hand avoid contact with personnel during inversion.
Claims5
A tube positioner for inverting a hand of tubes resting on a surface, comprising:
- clamp means for engaging opposed surfaces of the hand of tubes including a U-shaped frame, a guide bar having its opposite ends connected to the legs of the frame, and two sets of clamp arms carried by the frame and adapted to engage the opposed surfaces of the hand of tubes, one set of clamp arms being mounted on the guide bar for reciprocating movement therealong parallel to the other set of clamp arms;
- means for elevating and lowering the clamp means relative to said surface, after both sets of clamp arms engage the hand of tubes, along a first reference axis extending in a vertical direction;
- means for tilting the clamp means in its elevated condition, prior to inverting the hand of tubes, about a second reference axis extending perpendicular to the first reference axis and for returning the clamp means to its non-tilted condition after inverting the hand of tubes;
- means for inverting said clamp means and the hand of tubes engaged thereby about a third reference axis extending perpendicular to the second reference axis;
- and
- means for releasing said clamp means from the hand of tubes to deposit the inverted hand of tubes on the surface.
