Abstract

A loading device mounted to a collection vehicle is disclosed. The loading device may comprise several embodiments for scooping a soft-sided object through either a horizontal or vertical plane. The loading device is attached to a mechanized arm for compound angular displacement and operable between a stowed, extended, lift, and dump positions. A swivel mount interconnects the mechanized arm to the collection vehicle and further compounds the angular displacement and operating positions of the loading device.

Claims

1. A dual function apparatus for acquiring and transferring material to a receiving hopper of a collection vehicle, the apparatus comprising:

(a) an articulated mechanized arm connected to a collection vehicle, operable between stowed, extended, lift and dumping positions, and having a free end;

(b) a container grabbing mechanism comprising a pair of opposed arms connected to said free end of said mechanized arm and aligned in spaced relation operable for accessing, grasping and releasing a container, and fluid operated cylinder means connected to said pair of arms for opening and closing said opposed arms; and

(c) a pair of opposed mechanized scoops that are carried by and pivotally connected to said opposed arms and disposed to converge and diverge beneath said opposed arms when said opposed arms are in a grasping posture to scoop and release objects of interest, and fluid operated cylinder means connected between said opposed arms and said opposed mechanized scoops for opening and closing said opposed scoops.

2. The apparatus of claim 1 wherein said arm actuating means and said scoop actuating means comprise double acting hydraulic cylinders.

3. The apparatus of claim 1 wherein said container grabbing mechanism and said scoops are operable separately or in concert.

4. A dual function apparatus for acquiring and transferring material to a receiving hopper of a collection vehicle, the apparatus comprising:

(a) an articulated mechanized arm connected to a collection vehicle, operable between stowed, extended, lift and dumping positions, and having a free end;

(b) a container grabbing mechanism comprising a pair of mechanized, relatively movable opposed arms connected to said free end of said mechanized arm and aligned in spaced relation for accessing, grasping and releasing a container;

(c) a pair of opposed mechanized scoops that are carried by and pivotally connected to said opposed arms and disposed to converge and diverge beneath said opposed arms when said opposed arms are in a grasping posture to scoop and release objects of interest; and

(d) grabbing mechanism actuating means for operating said pair of opposed arms of said container grabbing mechanism between an open position and a grasping position.

5. The apparatus of claim 4, wherein each arm of said pair of opposed arms in said container grabbing mechanism comprises a plurality of sequentially articulated members.

6. The apparatus of claim 4 wherein said grabbing mechanism operates in a generally horizontal plane.

7. The apparatus of claim 4 wherein said scoop actuating means further comprises fluid operated means for actuating said pair of scoops to scoop and release objects of interest.

8. A dual function apparatus for acquiring and transferring material to a receiving hopper of a collection vehicle, the apparatus comprising:

(a) an articulated mechanized arm connected to a collection vehicle, operable between stowed, extended, lift and dumping positions, and having a free end;

(b) a container grabbing mechanism comprising a pair of mechanized, relatively movable opposed arms connected to said free end of said mechanized arm and aligned in spaced relation for accessing, grasping and releasing a container;

(c) a pair of opposed mechanized scoops that are carried by and pivotally connected to said opposed arms and disposed to converge and diverge beneath said opposed arms when said opposed arms are in a grasping posture to scoop and release objects of interest; and

(d) a grabbing mechanism support member rotationally connected to the free end of said articulated mechanized arm for carrying said container grabbing mechanism wherein said grabbing mechanism is pivotally attached to said grabbing mechanism support member.

9. A dual function apparatus for acquiring and transferring material to a receiving hopper of a collection vehicle, the apparatus comprising;

(a) an articulated mechanized arm connected to a collection vehicle, operable between stowed, extended, lift and dumping positions, and having a free end;

(b) a container grabbing mechanism comprising a pair of mechanized, relatively movable opposed arms connected to said free end of said mechanized arm and aligned in spaced relation for accessing, grasping and releasing a container;

(c) a pair of opposed mechanized scoops that are carried by and pivotally connected to said opposed arms and disposed to converge and diverge beneath said opposed arms when said opposed arms are in a grasping posture to scoop and release objects of interest;

(d) grabbing mechanism actuating means operating said pair of opposed arms of said container grabbing mechanism between an open position and a grasping position; and

(e) scoop actuating means for actuating said pair of scoops to scoop and release objects of interest, wherein said grabbing mechanism actuating means and said scoop actuating means are separately operable.

10. The apparatus of claim 9 further comprising mounting means for connecting said articulated mechanized arm to a collection vehicle.

11. The apparatus of claim 9 further comprising a grabbing mechanism support member rotationally connected to the free end of said articulated mechanized arm for carrying said container grabbing mechanism.

12. The apparatus of claim 9 wherein said pair of scoops are cup shaped.

13. The apparatus of claim 9 wherein said mechanized scoops pivot in a generally vertical plane.

14. The apparatus of claim 9 wherein said arm actuating means and said scoop actuating means comprise double acting hydraulic cylinders.

15. The apparatus of claim 14 wherein said scoop actuating means comprises double acting hydraulic cylinders connected between said opposed arms of said mechanized container grabbing mechanism and said scoops.

16. The apparatus of claim 9 wherein said container grabbing mechanism and said scoops are operable in concert.
