Abstract

A shoulder-blade incision-making apparatus is provided and includes: a fixing jig on which the poultry carcass which is eviscerated and which has leg parts removed is to be placed and fixed; a fixing jig conveyer forming a conveyance path of the fixing jig and convey the fixing jig along the conveyance path; a first separating member disposed above the conveyance path movably upward and downward; and a first driving device for moving the first separating member in an upward and downward direction. The first driving device is operated to move downward the first separating member and move the first separating member along a surface of the shoulder blade of the poultry carcass in accordance with a timing when the poultry carcass fixed to the fixing jig reaches a meat-separation position below the first separating member, therefore the meat portion attached to the shoulder blade is separated from the shoulder blade.

Claims

1. A shoulder-blade incision-making apparatus for separating a meat portion attached to a shoulder-blade of a poultry carcass from the shoulder-blade, comprising:

a fixing jig on which the poultry carcass which is eviscerated and which has leg parts removed is to be placed and fixed;

a conveyer forming a conveyance path of the fixing jig and configured to convey the fixing jig along the conveyance path;

a first separating member disposed above the conveyance path movably upward and downward; and

a first driving device for moving the first separating member in an upward and downward direction,

wherein the first driving device is operated to move downward the first separating member and move the first separating member along a surface of the shoulder-blade of the poultry carcass in accordance with a timing when the poultry carcass fixed to the fixing jig reaches a meat-separation position below the first separating member so that the meat portion attached to the shoulder-blade is separated from the shoulder blade,

wherein the first separating member includes a pair of scraper members disposed on opposite sides of a center line extending along the conveyance path and passing through a center of the fixing jig, across the centerline, and

wherein the pair of scraper members are oriented so that a distance between the scraper members gradually decreases toward a downstream side in a conveying direction of the poultry carcass.

3. The shoulder-blade incision-making apparatus according to claim 1, further comprising:

a second separating member disposed above the conveyance path and at an upstream side of the first separating member in a conveying direction of the fixing jig; and

a second driving device for moving the second separating member in an upward and downward direction,

wherein the second driving device is operated to move downward the second separating member in accordance with a timing when the poultry carcass fixed to the fixing jig reaches a meat-separation position below the second separating member, to separate a meat portion attached to a collar bone of the poultry carcass.

4. The shoulder-blade incision-making apparatus according to claim 3, further comprising:

a synchronizing device which includes;

a conveying-distance detection part for detecting a conveying distance of the fixing jig from a reference point of the conveyer; and

a control device for determining a timing to move downward the first separating member and the second separating member from a detection value detected by the conveying-distance detection part, and operating the first driving device and the second driving device to move downward the first separating member and the second separating member.

5. The shoulder-blade incision-making apparatus according to claim 4, further comprising:

a contour measurement part which includes;

a contact element disposed in the conveyance path at an upstream side of the second separating member in the conveying direction of the fixing jig;

an elastic support part for elastically supporting the contact element so that the contact element follows a surface of a shoulder section of the poultry carcass; and

a contour calculation part into which positional information of the contact element at a time when the contact element is in contact with the poultry carcass is to be inputted and which is configured to calculate a contour shape of the poultry carcass from the positional information,

wherein the controller is configured to determine the timing to move downward the first separating member and the second separating member from the detection value detected by the conveying-distance detection part and the contour shape of the poultry carcass obtained by the contour measurement part.

6. The shoulder-blade incision-making apparatus according to claim 3, wherein

the first separating member and the second separating member are supported on a single support base movably upward and downward.

7. The shoulder-blade incision-making apparatus according to claim 3, further comprising:

a first support base for supporting the first separating member movably upward and downward;

a second support base for supporting the second separating member movably upward and downward; and

a moving part which enables variation of a distance between the first support base and the second support base in the conveying direction of the fixing jig.

8. The shoulder-blade incision-making apparatus according to claim 5, wherein

the elastic support part comprises an air cylinder interposed between the first separating member and a support member supporting the first separating member.

9. The shoulder-blade incision-making apparatus according to claim 5, wherein

the elastic support part comprises a spring member interposed between the first separating member and a support member supporting the first separating member.
