Abstract
A device for selectively inserting or removing cup liners having a generally elongated cylindrical body, a front cup and a rear lip from a milking cup apparatus. The device having a frame, a force-applying device pivotally connected to the frame and a liner holding device, connected in sliding engagement to the frame. The liner holding device is configured to connect with the liner and to pull the liner through the hard milk shell cup when activated by a user.
Claims14
A device for selectively inserting or removing cup liners having a generally elongated cylindrical body, a front cup and a rear lip from a milking cup apparatus, said device comprising:
- a frame extending from a first end to a second end along a length;
- a force applying device, said force applying device connected to said frame, said force applying device configured to apply a first pre-selected force in a first direction and a second pre-selected force in a second direction;
- a liner connection device configured to connect a portion of a cup liner to said force applying device, wherein said liner connection device comprises a chute having a generally open portion connected to a base, said base held in sliding engagement against said frame, said base having a generally U-shaped riser extending upward from said base, said U-shaped riser having a bottom and a pair of sides, said U-shaped riser having a stop connected to said bottom and said sides of said U-shaped riser each defining a generally L-shaped aperture therein, said generally L-shaped aperture configured to receive a pair of rods therein, said pair of rods connected;
- to an upper clamping plate, said upper clamping plate connected to said force applying device whereby movement of said force applying device moves said pair of rods within said generally L-shaped apertures to alternatively compress or release an item held between one of said pair of rods and said stop, and to move said liner connection device in alternatively a first or second direction along said frame;
- and
- an actuator device operatively connected to said force applying device for selectively directing said force applying device to apply a pre-designated quantity of force in a selected direction;
- whereby a liner is connected to said liner connection device and a user activates said actuator device to cause said force applying device to apply a pre-selected quantity of force in a desired direction against said liner so as to selectively insert or remove said liner from said milking cup apparatus.

- a force applying device, said force applying device pivotally connected to said frame, said force applying device configured to apply a first pre-selected force in a first direction and a second pre-selected force in a second direction;
- a milking cup holding device connected to said frame, said milking cup holding device configured to hold a portion of a milking cup therein,
- a liner holding device, connected in sliding engagement along said frame, said liner holding device configured to connect a portion of a cup liner to said force applying device, wherein said liner holding device;
- comprises a chute having a generally open portion connected to a base, said base held in sliding engagement against said frame, said base having a generally U-shaped riser extending upward from said base, said U-shaped riser having a bottom and a pair of sides, said U-shaped riser having a stop connected to said bottom and said sides of said U-shaped riser each defining a generally L-shaped aperture therein, said generally L-shaped aperture configured to receive a pair of rods therein, said pair of rods connected to an upper clamping plate, said upper clamping plate connected to said force applying device, whereby movement of said force applying device moves said pair of rods within said generally L-shaped apertures to alternatively compress or release an item held between one of said pair of rods and said stop, and to move said liner holding device;
- in alternatively a first or second direction along said frame;
- and
- an actuator device operatively connected to said force applying device for selectively directing said force applying device to apply a pre-designated quantity of force in a selected direction;
- whereby when a milking cup apparatus is positioned within said milk cup holding device and said liner holding device is connected to a liner, said actuator device activates said force applying device to apply a pre-selected quantity of force in a desired direction against said liner so as to selectively insert or remove said liner from said milking cup apparatus.
