Japanese Patent Laid-Open No. 11-2 having the above configuration as a main configuration
The automatic deboning means and its device disclosed in Japanese Patent Publication No. 66780 also have unsolved and insufficient points. The problems are the problem of crushing and mixing of the triangular bone into the breast found in the breast stripping process and the problem of tearing the fillet in the fillet removing process. The problem of the crushed pieces being mixed into the peeled breast due to the crushing of the triangular bone is that, as shown in the perspective view of FIG. Is formed of a triangular thin plate-like bone piece extending in the breast, and the triangular bone 115 is damaged in the breast-stripping step, and the fragment is mixed into the peeled breast, and there is a problem of foreign matter intervening in the breast. Is formed.

[0012] The problem of tearing the fillet in the fillet removing step is described in Japanese Patent Application Laid-Open No. H11-266780, in which a method is used in which a thin film layer on the fillet surface is scored with a rotary blade having a shallow cutting edge. In this case, the adhesive force between the side surfaces of the wide bevel (sternal bone) 116 located at the tip of the bird's ostium 106 and the fillet is large, and the fillet of the fillet With only the method, there is a problem in that when the scissors are removed, the scissors are torn and the commercial value is reduced.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and has a difference between the left and right of the work from the loading and mounting of the upper body of the chicken carcass to the removal of the breast through the separation of the breast meat and fillet by the required deboning process. Absorption of individual differences such as the size of the work and the imbalance of the left and right of each work, etc., complete removal of foreign matter due to triangular crushing when stripping the breast, and no cutting of the fillet in the fillet removal process, resulting in high yield. It is an object of the present invention to provide a method for automatically deboning the upper body of a chicken carcass and an apparatus therefor which enable complete unmanned operation.

[0014]

SUMMARY OF THE INVENTION Accordingly, in the automatic deboning method for the upper body of a chicken carcass according to the present invention, a work composed of the upper body of a chicken carcass is set to a position directly facing a shoulder-plated cone and a wing rest. After measuring the mounted work in the joint width direction based on individual differences,
