In the following description, the directions of arrows I, II, III, IV, V, and VI in FIGS. 1 to 6 are referred to as forward, rearward, leftward, rightward, upward, and downward, as shown in FIGS. The breast peeling device A in the upper half of the poultry carcass has a cut in the left and right shoulder joints, more specifically, a cut through the shoulder joint from the thorax on the chest side to the scapula on the back side. In addition, while holding the upper part of the poultry carcass 100 by fitting it into the thoracic cavity of the upper part of the poultry carcass 100 from below, the poultry carcass is shown forward in FIG. The holding member 1 that moves in the direction of the back of the upper half 100 and the left and right shoulder joints 101 of the poultry carcass upper half 100 that move forward, more specifically, an oval shape on the wing 102 side of the shoulder joint A pair of left and right holding members 2 and 3 for vertically holding a portion between the joint ball 103 and the glenoid fossa 104 on the rib cage side of the shoulder joint; Left and right wings of the upper half 100 of the poultry carcass 100 in which the left and right shoulder joints 101 are sandwiched between the pair of upper and lower sandwiching members 2 and 3 and move forward with the left and right wings 102 protruding outside the left and right sandwiching members 2 and 3. The wing movement prevention member 4 that abuts the base of the wing 101 from the front, that is, the back side, and prevents the left and right wings 101 from moving forward, and the holding member 1 is rotated to cause the bases of the left and right wings 101 to move. A first cam 5 is provided for lowering the upper half 100 of the poultry carcass abutting against the stop member 4 forward, that is, to the back.
As shown in FIG. 1, the holding member 1 has a substantially "L" shaped driven portion 1a near the lower end thereof, and is rotatable around a left-right rotation shaft 1b immediately above the driven portion 1a.

The upper member 2 in the pair of upper and lower holding members is divided into a rear portion, that is, a first portion 2a on the rear side in the moving direction of the support member 1, and a second portion 2b on the center and front side. The first portion 2a through the slide guide 2a ₁ to be vertically moved at a predetermined permissible range, and is supported by the frame of the breast meat stripper A. Uppermost position of the first portion 2a is a position where the height of the front lower end 2a ₂ of the first portion 2a matches the height of the rear lower end 2b ₁ of the second portion 2b, the lowest position of the first portion 2a Is a position where the lower edge of the first portion 2a faces the upper edge of the lower member 3 in the pair of upper and lower holding members with a predetermined minute gap therebetween. The first portion 2a is biased downward by the weight 2a _3.

As can be seen from FIG. 2, the distance between the first portions 2a of the left and right upper members increases toward the front, that is, toward the moving direction of the support member 1. The maximum value of the distance between the first parts 2a of the left and right upper members, that is, the distance between the left and right first parts 2a at the front end of the first part 2a is larger than the distance between the left and right shoulder joints of a bird with a large shoulder width. Is set. The minimum value of the distance between the first parts 2a of the left and right upper members, that is, the distance between the left and right first parts 2a at the rear end of the first part 2a is less than the distance between the left and right shoulder joints of a bird with a small shoulder width. Is set. The distance between the second portions 2b of the left and right upper members is set to the same value as the maximum value of the distance between the first portions 2a of the left and right upper members. The distance between the left and right lower members 3 is larger than the distance between the left and right first members 2a in the region facing the first portion 2a of the upper member, and is larger in the region facing the second portion 2b of the upper member. It is set to the same value as the distance between the second portions 2b of the left and right upper members.

As shown in FIG. 1, the breast peeling device A for the upper half of the poultry carcass is located just before the first portion 2a of the upper member in the pair of upper and lower sandwiching members, more precisely, in the immediate vicinity of the first portion 2a. At the rear, a pair of upper and lower second cams 6a and 6b are provided, which rotate the holding member 1 to tilt the upper half of the poultry carcass 100 rearward, that is, to the chest side.

The operation of the breast peeling device A for the upper half of the poultry carcass will be described.
As shown in FIGS. 1 and 4 (a), the upper half 100 of the poultry carcass, in which a cut is made through the shoulder joint 101 from the holding member 1 and thus the thorax on the thoracic side to the scapula on the dorsal side, Approaching a pair of upper and lower sandwiching members 2, 3. One side of the driven portion 1a of the holding member 1 is brought into contact with the flat upper edge 6b ₁ of lower cam 6b, the holding member 1 thus poultry carcasses upper half 100 is upright.

Immediately before the poultry carcass upper half 100 enters the holding members 2 and 3, that is, immediately behind the first portion 2a of the upper member in the pair of upper and lower holding members, as shown in FIG. follower 1a reaches the gap between the upper cam 6a and the lower cam 6b, the side of the driven portion 1a is released the contact between the flat upper edge 6b ₁ of lower cam 6b, the lower cam 6b facing the recess 6b ₂ of the edge.
Due to the weight of the supporting member 1 and the upper half 100 of the poultry carcass, the supporting member 1 falls down around the rotation axis 1b in the traveling direction, that is, toward the chest. As shown in FIG. 4 (c), the driven portion 1a is brought into contact with the recessed portion 6b ₂ of the lower edge and the lower cam 6b on the edge of the upper cam 6a, the support member 1 and thus of the poultry carcasses on half 100 The inclination toward the chest is regulated to a predetermined value. As a result, the poultry carcass upper half 100 enters the holding members 2 and 3 while being inclined at a predetermined angle toward the chest.
The left and right shoulder joints 101 of the poultry carcass upper half 100, more specifically, the portion between the oval joint ball 103 on the wing side of the shoulder joint 101 and the glenoid fossa 104 on the thoracic side of the shoulder joint is left and right pinched. The member enters a vertical gap between the first portion 2a of the upper member 2 of the member and the lower member 3, and is held by the member. Since the poultry carcass upper half 100 is inclined to the chest side by a predetermined angle and the breast is directed obliquely downward, the first portion 2a of the upper member 2 approaching the poultry carcass half 100 from above is It touches the shoulder joint 101 without touching the breast. As a result, the holding members 2 and 3 hold the shoulder joint 101 without holding the breast.
The upper half 100 of the poultry carcass is maintained at a predetermined inclination angle toward the chest, so that the holding members 2, 3 can stably hold the shoulder joint 101.

The first portion 2a of the upper member 2 is vertically movable and urged downward by the weight 2a ₃ , and the lower edge of the first portion 2a faces the upper edge of the lower member 3 with a predetermined minute gap. Therefore, the shoulder joint 101 enters the vertical gap between the first part 2a and the lower member 3 while pushing up the first part 2a. Therefore, even when the size of the upper half 100 of the poultry carcass is small and the shoulder joint 101 is small, the first portion 2a is in contact with the shoulder joint, and the holding members 2 and 3 are thus shouldered regardless of the size of the shoulder joint 101. The joint 101 can be clamped.
Urging downward the first region 2a by weight 2a ₃ is stable as compared to other biasing by simmer biasing means such as a spring. As a result, the holding of the shoulder joint 101 by the holding members 2 and 3 is stabilized.

Since the distance between the left and right first portions 2a increases in the moving direction of the support member 1, the contact portion between the first portion 2a and the upper half of the poultry carcass 100 is With the movement of the part 100, it moves outward from the inside of the shoulder toward the shoulder joint 101 and approaches the shoulder joint 101. As a result, the holding of the shoulder joint 101 by the holding members 2 and 3 is realized.
The minimum value of the distance between the left and right first parts 2a at the rear end of the first part 2a is set to be less than the distance between the left and right shoulder joints of the bird with a small shoulder width, and the first left and right parts at the front end of the first part 2a. Since the maximum value of the distance between 2a is set to be larger than the distance between the left and right shoulder joints of a poultry with a large shoulder width, regardless of the size of the upper half 100 of the poultry carcass, specifically, the left and right shoulder joints Regardless of the distance, when the upper half of the poultry carcass reaches the front end of the first part 2a, the first part 2a comes into contact with the egg-shaped joint ball 103 on the wing side of the shoulder joint 101 and becomes ovoid. The joint ball 103 is pressed outward. Therefore, the pair of upper and lower holding members 2 and 3 can hold the shoulder joint 101 regardless of the distance between the left and right shoulder joints.
When the upper half 100 of the poultry carcass reaches the front end of the first part 2a, the clamping of the shoulder joint 101 by the clamping members 2, 3 is realized. Firm holding of the shoulder joint 101 is maintained.

As shown in FIGS. 5A and 5B, when the driven portion 1a reaches near the front end of the upper cam 6a, the contact between the driven portion 1a and the lower edge of the upper cam 6a is released, and the rotation of the support member 1 is started. As the movement becomes possible, the gap between the upper and lower holding members 2 and 3 holding the shoulder joint 101 becomes ascending, and the support member 1 and eventually the poultry carcass upper half 100 begin to rise. Figure 5 (c), the at the time when the shoulder joint 101 has reached the top of the climb gradient of the gap between the upper and lower clamping members 2 and 3, the flat ends have recessed portions 6b ₂ on the lower cam 6b edge the upper edge 6b ₁ is restored such. One side of the driven portion 1a is brought into contact with the flat upper edge 6b _1, the support member 1 thus poultry carcasses upper half 100 is returned to the upright position.

  As shown in FIGS. 6 (a) and 6 (b), when the shoulder joint 101 passes through the top of the up-slope of the gap between the upper and lower sandwiching members 2, 3, and reaches the down-slope portion of the gap. The front edge of the lower end of the support member 1 contacts the first cam 5. As a result, as the support member 1 moves forward, the support member 1 and thus the poultry carcass upper half 100 fall forward, that is, to the dorsal side. As shown in FIG. 6 (c), the support member 1 and thus the poultry carcass upper half 100 fall down until they become substantially horizontal. When the poultry carcass upper half part 100 moves forward and falls forward to a substantially horizontal position, the rear part of the base of the left and right wings 102 comes into contact with the left and right wing movement prevention members 4 to move forward. Movement is restricted. The trunk of the poultry carcass upper half 100 continues to move forward and falls forward, that is, falls back. The torso of the poultry carcass upper half 100, which is cut through the shoulder joint from the thorax on the thoracic side to the scapula on the dorsal side, moves to the dorsal side with the left and right wings 102 restricted from moving. While falling to the back side, the left and right wings 102 and the breast are peeled from the trunk of the upper half 100 of the poultry carcass.

  Next, the wing movement preventing member 4 moves to the retreat position away from the sandwiching members 2 and 3, and the left and right pushing members 7 shown in FIG. The left and right wings 102 and the breast which have been released are separated from the holding member 1. As a result, the left and right wings 102 and the breast are completely separated from the trunk. The wing movement preventing member 4 returns to the operating position close to the holding members 2 and 3. The left and right wings 102 are separated from the breast, and the breast and the left and right wings 102 are separately collected.

  As can be seen from the above description, in the breast peeling device A for the upper half of the poultry carcass, the holding members 2, 3 can hold the shoulder joint without holding the breast.

INDUSTRIAL APPLICABILITY The present invention can be widely used for stripping the breast of the upper half of a poultry carcass.
