Feeding system
The disclosure is directed to a feeding system. The feeding system includes a housing that substantially forms an exterior surface of the feeding system, inside the housing includes an arm configured to rotate clockwise and counterclockwise to a plurality of positions, wherein the arm is configured to support a can; a can opener at a first position of the plurality of positions; and an opening of the housing at a second position of the plurality of positions. A sealed-can barrel is situated to receive and store a stack of sealed cans within the housing, and a cam-operated latch device is provided to release a bottommost can of the stack onto the arm. In timed operations, a cam-operated retainer device is configured to hold a plurality of sealed cans of the stack above the bottommost sealed can while the bottommost sealed can is being released onto the arm.
1 . A feeding system comprising:
a housing that substantially forms an exterior surface of the feeding system, inside the housing comprising:
an arm configured to rotate clockwise and counterclockwise to a plurality of positions, wherein the arm is configured to support a can comprising food contents, wherein the plurality of positions comprise a can-opening position, a feeding position, and a sealed-can placement position;
a can opener at the can-opening position to provide an opened can;
an opening of the housing at the feeding position, wherein the food contents of the opened can are accessible at the feeding position for feeding from the opened can, wherein the arm moves the can to the can-opening position and the feeding position;
a sealed can barrel structure for housing a vertically disposed stack of sealed cans at the sealed-can placement position;
a latch dispensing device associated with said sealed can barrel structure, the latch dispensing device extendable to support the stack of sealed cans within the sealed can barrel structure;
a base support platform adapted to rotate, said arm disposed on said base support platform and rotatable therewith to locate the arm at each of the plurality of positions; and
a retainer device disposed at a sidewall of said sealed can barrel, said retainer device extendable to retain one or more sealed cans disposed above a bottommost can of the stack of sealed cans at the sealed-can placement position;
a cam structure mounted on the rotating base support platform for rotation therewith, wherein the latch dispensing device and retainer device are cam-operated, said retainer device having a cam-follower element disposed for engaging said cam structure while the base rotates to one or more of said plurality of positions; and
said latch dispensing device having a cam-follower element disposed for engaging said cam structure while the base rotates to one or more of said plurality of positions, and the latch dispensing device cam-follower element engaging said cam structure to retract and release only the bottommost can of the stack from within the sealed can barrel onto the arm while the retainer device cam-follower element engages said cam structure to extend the retainer device to retain the sealed cans disposed above the bottommost sealed can being released onto the arm.
2 . The feeding system of claim 1 , wherein the retainer device comprises:
a substantially flat spring steel body pivotable about an axis and one or more retaining arms at a distal end, each one or more retaining arms extending outward from the flat spring steel body for gripping a sealed can within the sealed can barrel structure while the bottommost can of the stack is being released.
3 . The feeding system of claim 2 , wherein each said extended one or more retaining arms comprises toothed-edges for gripping and holding a sealed can disposed above the sealed bottommost can being released from the sealed can barrel onto the arm.
4 . The feeding system of claim 3 , wherein said retainer device is disposed proximate a surface of said sealed can barrel, said one or more retaining arms at said distal end being extended and retracted through corresponding openings of said sealed can barrel.
5 . The feeding system of claim 1 , wherein the cam structure comprises:
a first cam surface, wherein said cam-follower element of said latch dispensing device engages said first cam surface; and
a second cam surface, wherein said cam-follower element of said retainer device engages said second cam surface, said first cam surface having a first cam surface profile and second cam surface having a second cam surface profile, said first and second cam surface profiles configured for timing the latch device to release said bottommost sealed can onto said arm as the base member rotates while the retainer device simultaneously retains one or more sealed cans above the bottommost sealed can being released.
6 . The feeding system of claim 5 , wherein said cam-follower element of said latch dispensing device is a horizontally oriented wheel adapted for engaging the first cam surface of the cam structure as the base support platform rotates.
7 . The feeding system of claim 1 , further comprising an elevation screw that is configured to rotate and move the arm vertically upwards and downwards.
8 . The feeding system of claim 7 , wherein the arm comprises:
a plural member linkage assembly having a support pad at a distal end thereof for supporting a can, said linkage assembly operatively connected to the elevation screw for vertically raising and lowering said arm and support pad to a desired height.
9 . The feeding system of claim 8 , wherein the support pad is disposed horizontally while said arm is vertically raised or lowered to a desired height in response to rotation of said elevation screw.
10 . The feeding system of claim 9 , further comprising: a height adjustment nut disposed on said elevation screw and locatable at pre-defined heights in the vertical direction in response to rotation of said elevation screw, said height adjustment nut controlling an extent to which the arm and said support pad can be raised in the vertical direction.
11 . The feeding system of claim 10 , wherein the height adjustment nut comprises one or more guide posts extending outward therefrom, said plural member linkage assembly comprising one arm member having slots at opposing sides for slidable engagement with a respective extended guide post, said arm member and support pad vertically raised to the desired height in the vertical direction based on a height of the height adjustment nut.
12 . The feeding system of claim 8 , wherein the support pad is disposed at one or more angles relative to a horizontal while said arm is vertically raised in response to rotation of said elevation screw at respective one or more pre-defined positions.
