Abstract
A system and method that is adapted to remove portions of a neck-bone that are useful for meat recovery systems. These most useful portions of the neck bone structure are the outer edges distal from the core of the bone that have meat attached to them. The useful portions on the outer edges distal from the core can be safely removed and subsequently processed in downstream processes such as mechanical separators (bone cannons) or hand trimmed. The overall system contains series sub systems to process neck-bones. The subsystems includes, a Product Infeed; a Chain Drive System; a Cutting Apparatus; a Cat Chain; a Core Extractor System; and a Conveyor Washing System.
Claims25
An apparatus for processing a neck bone for meat recovery comprising:
- an infeed conveyor having a conveyance surface adapted to support and convey a product along a path of conveyance;
- a feather-bone guide rod extending lengthwise and adjacently along the path of conveyance and disposed proximately above the conveyance surface;
- and
- a lateral guide rod extending lengthwise and adjacently along the path of conveyance and disposed proximately above the conveyance surface and proximately laterally spaced apart from the feather bone guide rod where the spacing between the lateral guide rod and the featherbone guide rod is gradually reduced.

An apparatus for processing a neck bone for meat recovery comprising:
- a flattened guide rail having proximately vertically spaced apart upper and lower flattened elongated flanges extending substantially parallel one with respect to the other and forming a lengthwise gap there between and extending adjacent to and along a path of conveyance and where said lengthwise gap is adapted to receive product therein and where the upper elongated flattened flange has a lengthwise elongated side notch;
- and
- a vertically oriented cat chain of a cat chain drive where the top run and bottom run of the cat chain extend in the direction of the path of conveyance and the bottom run extending and aligned proximately above the elongated side notch and said cat chain having laterally space apart flanges, which extend substantially vertically when traveling along a bottom run thereby forming a capture space there between and having a plurality of cleats vertically extending from the cat chain and in the capture space when traveling along the bottom run.
An apparatus for processing a neck bone for meat recovery comprising:
- a flattened guide rail having proximately vertically spaced apart upper and lower flattened elongated flanges extending substantially parallel one with respect to the other and forming a lengthwise gap there between and extending adjacent to and along the path of conveyance and where said lengthwise gap is positioned to receive product therein from the infeed conveyor;
- a horizontally oriented infeed chain drive where a side run is vertically aligned and proximately adjacent the lengthwise gap;
- a circular saw blade of a circular saw extending vertically upward through a cut-out in the upper and lower elongated flanges;
- a substantially vertically oriented band saw blade of a substantially vertically oriented band saw extending proximately adjacent the lengthwise gap for effecting a substantially vertical cut;
- a vertically oriented cat chain of a cat chain drive where the top run and bottom run of the cat chain extend in the direction of the path of conveyance and the bottom run extending and aligned proximately above the elongated side notch and said cat chain having laterally space apart flanges, which extend substantially vertically when traveling along a bottom run thereby forming a capture space there between and having a plurality of cleats vertically extending from the cat chain and in the capture space when traveling along the bottom run;
- and
- a horizontally oriented extraction chain drive vertically aligned and proximately adjacent the lengthwise gap.
4 more elements
An method for processing a neck bone for meat recovery comprising the steps of:
- advancing a product along a flattened guide rail having proximately vertically spaced apart upper and lower flattened elongated flanges extending substantially parallel one with respect to the other and forming a lengthwise gap there between and where said product advances through the lengthwise gap by conveying along with a horizontally oriented infeed chain drive where a side run of the chain drive is vertically aligned and proximately adjacent the lengthwise gap;
- cutting away a lateral side portion of the product with a circular saw extending vertically upward through a cut-out in the upper and lower elongated flanges;
- cutting away an opposing lateral side portion of the product with a substantially vertically oriented band saw extending proximately adjacent the lengthwise gap for effecting a substantially vertical cut;
- and
- transitioning the product to a horizontally oriented extraction chain drive vertically aligned and proximately adjacent the lengthwise gap utilizing a vertically oriented cat chain of a cat chain drive where the top run and bottom run of the cat chain extend in the direction of the path of conveyance and the bottom run extending and aligned proximately above the elongated side notch and said cat chain having laterally space apart flanges, which extend substantially vertically when traveling along a bottom run thereby forming a capture space there between and capturing the product therein and advancing with a plurality of cleats vertically extending from the cat chain and in the capture space when traveling along the bottom run.
2 more elements
An apparatus for processing a neck bone for meat recovery comprising:
- a vertically oriented cat chain of a cat chain drive where the top run and bottom run of the cat chain extend in the direction of the path of conveyance and the bottom run extending and aligned proximately above the elongated side notch and said cat chain having laterally space apart flanges, which extend substantially vertically when traveling along a bottom run thereby forming a capture space there between and having a plurality of cleats vertically extending from the cat chain and in the capture space when traveling along the bottom run.
An apparatus for processing a neck bone for meat recovery comprising:
- an elongated feather bone guide rod articulatedly mounted proximately above a conveyor belt defining a direction of conveyance and said feather bone guide rod extending lengthwise in the direction of conveyance and an elongated lateral guide rod articulatedly mounted proximately above the conveyor belt extending lengthwise in the direction of conveyance and laterally spaced apart from said feather bone guide rod, where the feather bone guide rod is adapted to capture feather bones attached to a neck bone structure underneath while laterally aligning the feather bone side of the neck bone structure and where the lateral guide rode is adapted to laterally align a side of a neck bone structure opposite a feather bone side;
- and
- a sprocketed alignment wheel articulatedly mounted proximately above the conveyor belt laterally positioned between the featherbone guide rod and the lateral guide rod and having a direction of rotation in line with the direction of conveyance.
