Apparatus for removing a stockinette
One aspect of the invention includes an automated method of removing a stockinette from meat having an end, sides, and a length. The stockinette enveloped meat is conveyed in a first direction as the stockinette is cut proximate the end of the meat with a first knife. The stockinette enveloped meat is then conveyed in a second direction as the stockinette is cut proximate the sides of the meat with a second knife and a third knife. The cuts made by the second knife and the third knife intersect with the cut made by the first knife. The cuts in the stockinette create a flap in the stockinette between the cuts. The flap is engaged and peeled away from the meat, and the meat is removed from the stockinette.
1. An automated stockinette remover for removing a stockinette from meat, the meat having an end, sides, and a length, comprising:
a) a conveyor having a conveying member configured and arranged to support and transport the meat in a first direction;
b) a first knife proximate the conveying member, the first knife being positioned for making a first cut in the stockinette proximate the end of the meat parallel to the first direction as the meat is transported in the first direction, the first cut extending perpendicular to the sides and the length of the meat;
c) a passageway proximate the conveying member, the passageway extending outward from the conveying member in a second direction approximately perpendicular to the first direction;
d) a transfer member to transport the meat from the conveying member in the second direction into and through the passageway;
e) a second knife and a third knife positioned proximate the passageway, the second knife and the third knife positioned for concurrently making a second cut and a third cut in the stockinette proximate the sides of the meat as the meat is transported through the passageway, the second cut and the third cut intersecting the first cut and extending along the length of the meat; and
f) an engaging member proximate the passageway configured and arranged to engage the stockinette between the cuts in the stockinette to remove the stockinette from the meat.
2. The automated stockinette remover of claim 1 , further comprising a plurality of carriages operatively connected to the conveying member of the conveyor configured and arranged to support the meat.
3. The automated stockinette remover of claim 1 , further comprising an indexing member parallel to the first direction proximate the conveying member, the first cut being a predetermined distance from the indexing member.
4. The automated stockinette remover of claim 1 , wherein the first knife, the second knife, and the third knife are spring loaded.
5. The automated stockinette remover of claim 1 , wherein the transfer member is a piston rod actuated by an air cylinder.
6. The automated stockinette remover of claim 1 , further comprising an engaging surface on the engaging member, the engaging surface contacting the stockinette and the meat during removal of the stockinette from the meat.
7. The automated stockinette remover of claim 6 , wherein the engaging member is a rotatable shaft and the engaging surface is a row of pins on the rotatable shaft, the row of pins snagging the stockinette and the stockinette winding about the shaft to peel the stockinette away from the meat as the shaft is rotated thereby removing the stockinette from the meat.
8. The automated stockinette remover of claim 7 , further comprising a vacuum source to remove the stockinette from the rotatable shaft.
9. The automated stockinette remover of claim 1 , wherein the engaging member is rotatable in a first direction to wind a portion of the stockinette about the engaging member to remove the stockinette from the meat, and wherein the engaging member is rotatable in a second direction to unwind the portion of the stockinette from the engaging member to remove the stockinette from the engaging member.
10. The automated stockinette remover of claim 9 , wherein the engaging member contacts the meat to prevent the stockinette from pulling about the meat and damaging the meat during removal of the stockinette.
11. An automated stockinette remover for removing a stockinette from meat, the meat having an end, sides, and a length, comprising:
a) a conveyor configured and arranged to transport the meat in a first direction;
b) a first knife proximate the conveyor positioned for making a first cut in the stockinette proximate the end of the meat, the first cut being parallel to the first direction and perpendicular to the sides and the length of the meat;
c) a transfer member to transport the meat in a second direction into and through a passageway, the second direction being approximately perpendicular to the first direction;
d) a second knife and a third knife positioned proximate the passageway, the second knife and the third knife positioned for concurrently making a second cut and a third cut in the stockinette proximate the sides of the meat as the meat is transported through the passageway, the second cut and the third cut intersecting the first cut and extending along the length of the meat; and
e) an engaging member proximate the passageway configured and arranged to engage the stockinette between the cuts in the stockinette and to remove the stockinette from the meat.
12. The automated stockinette remover of claim 11 , further comprising an indexing member parallel to the first direction proximate the conveyor, the indexing member ensuring the first cut is made a predetermined distance from the end of the meat.
13. The automated stockinette remover of claim 11 , further comprising a vacuum source to remove the stockinette from the engaging member.
14. The automated stockinette remover of claim 11 , further comprising an engaging surface on the engaging member, the engaging surface snagging the stockinette and contacting the meat during removal of the stockinette from the meat.
15. The automated stockinette remover of claim 14 , wherein the engaging member is a rotatable shaft and the engaging surface is a row of pins on the rotatable shaft, the row of pins snagging the stockinette and the stockinette winding about the shaft to peel the stockinette away from the meat as the shaft is rotated thereby removing the stockinette from the meat.
16. The automated stockinette remover of claim 11 , wherein the first knife, the second knife, and the third knife are spring loaded.
17. The automated stockinette remover of claim 11 , wherein the transfer member is a piston rod actuated by an air cylinder.
18. The automated stockinette remover of claim 11 , wherein the engaging member is rotatable in a first direction to wind a portion of the stockinette about the engaging member to remove the stockinette from the meat, and wherein the engaging member is rotatable in a second direction to unwind the portion of the stockinette from the engaging member to remove the stockinette from the engaging member.
19. The automated stockinette remover of claim 18 , wherein the engaging member contacts the meat to prevent the stockinette from pulling about the meat and damaging the meat during removal of the stockinette.
