  In FIG. 1, in the automation device 10 of this embodiment, an endless chain 12 is wound between a drive sprocket 14 and a driven sprocket 16 and arranged in a horizontal direction. The endless chain 12 is moved in the direction of arrow a by the drive sprocket 14. A number of cones 18 are mounted on the endless chain 12 at equal intervals. The cone 18 is erected on the outward path from the workpiece input part A to the bevel cut part B and the kappa removal part C, and is inverted on the return path from the kappa removal part C to the work input part A. An operation panel 23 is provided at the upper end of the central column 21. A discharge conveyor 70 is provided below the drive sprocket 14.

  In FIG. 2, the cone body 180 into which the workpiece is inserted is fixed in an upright state on a base plate 182 fixed to the endless chain 12. A pair of fixed arms 184 and a movable arm 186 are mounted on both side surfaces of the cone body 180. The fixed arm 184 and the fixed arm 184 are provided with presser plates 184a and 186a for pressing the work from both sides. The fixed arm 184 is fixed to the side surface of the cone body 180. The movable arm 186 is connected to the rotation shaft 188. A cylindrical cam 190 is rotatably mounted on the rotating shaft 188 on the back side of the cone body 180, and a receiving plate 192 is integrally connected thereto.

  A screw shaft 194 is erected on the base plate 182, and the screw shaft 194 is inserted into a hole formed in the receiving plate 192. A nut 196 is screwed to the upper end of the screw shaft 194. A coil spring 198 is interposed between the base plate 182 and the receiving plate 192, and the receiving plate 192 is pushed upward by the spring force of the coil spring 198 and is locked to the nut 196. In this state, the movable arm 186 is retracted from the fixed arm 184, and the presser plates 184a and 186a are separated from each other. The upper end of the presser plate 186a has an L shape, and the upper end of the presser plate 184a has a planar shape that is inclined rearward with respect to the presser plate 186a. The shape of these presser plates increases the clamping force for the work and strengthens the work.

  The surface 180a of the cone body 180 on the side where the work is gripped by the pressing plates 184a and 186a is formed in a flat shape. By abutting the workpiece against the flat surface 180a, the workpiece is stably held. A lower flat surface 180b that is recessed by one step is formed below the flat surface 180a. As a result, a round bar 22 and a second cutting blade 26, which will be described later, can be disposed close to the cone body 180. A cutout portion 180 c is formed at the upper end of the cone body 180 so that a tip portion 44 a of a first round bar 44 described later can be disposed close to the upper portion of the cone body 180.

  3 and 4 show the workpiece input unit A. FIG. In the workpiece loading part A, a workpiece positioning guide 20 and a round bar 22 are arranged in the horizontal direction on the front side of the cone 18. The operator inserts and fixes the workpiece w to the cone 18. That is, the neck portion n is turned up and the sternum ridge 130 is placed on the front side, that is, the presser plates 184a and 186a, and is inserted. The upper surface of the workpiece positioning guide 20 forms a horizontal reference plane h, the sternum crest 130 hits the horizontal reference plane h, and the bevel 132 hits the round bar 22, whereby the workpiece w is positioned in the vertical direction. In this state, the chain 12 is operated, the cone 18 is conveyed in the direction of arrow a, and the workpiece w is conveyed to the bevel cut portion B on the downstream side while being positioned in the vertical direction. The workpiece positioning guide 20, the round bar 22, the fixed arm 184 and the movable arm 186 constitute a fixing device 19.

  5 to 7 show the bevel cut portion B. FIG. In the bevel cut portion B, the first cutting blade 24 is provided on the upstream side in the transport direction facing the transport path of the workpiece w, and the second cutting blade 26 is provided immediately downstream of the first cutting blade 24. . The workpiece positioning guide 20 and the round bar 22 are arranged just before the conveying direction of the first cutting blade 24. A guide rail 28 is disposed in the horizontal direction along the conveying path of the cone 18 in the bevel cut portion B and the kappa removal portion C located on the downstream side thereof. The guide rail 28 is disposed from immediately upstream of the first cutting blade 24 to above the drive sprocket 14.

  As shown in FIG. 6, the first cutting blade 24 has a trapezoidal plate shape and is arranged in the horizontal direction. The blade 24a of the first cutting blade 24 is disposed obliquely with respect to the conveyance path of the workpiece w. As a result, the workpiece w is conveyed in the direction of the arrow a, so that the blade 24a gradually approaches the workpiece w and cuts the bevel 132 located below the sternum ridge 130. In this case, the blade 24a gradually approaches the bevel 132 from the front side in FIG. 6 to cut the bevel 132 in the horizontal direction. Initially, an experiment was conducted in which the bevel 132 was cut with a wedge-shaped plate-shaped cutting blade (blade shape indicated by a two-dot oblique line 24a ′ in FIG. 6) with the blade edge directed in the direction opposite to the arrow a direction.

  However, it has been found that this cutting blade may cut the inner branch bone 144 adjacent to the bevel 132 simultaneously with the bevel 132. When the inner branch bone 144 is cut, the inner branch bone 144 is mixed with the cut bevel 132, so that it is necessary to remove the inner branch bone 144. On the other hand, only the bevel 132 can be cut by using the blade 24a.

  As shown in FIG. 7, the first cutting blade 24 is arranged so as to have an angle θ (15 to 20 °) with respect to the horizontal plane H. If the 1st cutting blade 24 is arrange | positioned in the horizontal direction, the bevel 132 will be cut | disconnected by the line c of FIG. On the other hand, in this embodiment, since the 1st cutting blade 24 has angle (theta), the bevel 132 can be cut | disconnected by the line c1. Since the bevel 132 has a boundary along the line c1, the volume of the bevel 132 can be increased by cutting the bevel 132 along the line c1.

  In FIG. 7, the guide rail 28 pushes the cam 190 downward at a position immediately upstream of the first cutting blade 24, rotates the movable arm 186, closes the press plates 184a and 186a, and moves the sternum crest 130 from both sides. The sternum crest 130 is pinched and fixed. Then, on the downstream side of the kappa removing portion C, the press of the cam 190 is released, the press plate 186a is retracted, and the press of the sternum ridge 130 is released. The kappa 120 falls onto the kappa discharge conveyor 70 when the endless chain 12 is reversed above the drive sprocket 14.

  The second cutting blade 26 is arranged in the vertical direction, has a wedge-shaped plate shape that becomes wider toward the downstream side in the conveying direction of the cone 18, and a blade 26 a is formed on the lower side in the oblique direction. By transporting the workpiece w in the direction of arrow a, the tip of the second cutting blade 26 is inserted inside the bevel 132, that is, the membrane 146 attached between the bevel 132 and the inner branch bone 144. The film 146 is cut off by the second cutting blade 26 along with the conveyance of the workpiece w and cut down downward.

  On the front side of the second cutting blade 26 (the front side of the second cutting blade 26 in FIG. 6), a presser bar 30 made of a round bar is disposed along the arrow a direction. The presser bar 30 is arranged in parallel with the second cutting blade 26 so as to sandwich the bevel 132, and gradually increases the distance from the second cutting blade 26 toward the downstream side in the conveyance direction of the workpiece w. Is arranged. A bevel discharge chute 32 is provided below the second cutting blade 26 and the presser bar 30. With this configuration, in the first half of the presser bar 30, while the film 146 is being cut by the second cutting blade 26, the bevel 132 is placed outside the second cutting blade 26 with the second cutting blade 26 and the presser bar 30 sandwiching the bevel 132. In the second half of the presser bar 30, the film 146 is separated by the second cutting blade 26, and the bevel 132 can be dropped onto the bevel discharge chute 32.

Both ends of the frame 34 are supported by guide bars 38a and 38b arranged in the vertical direction so as to be slidable in the vertical direction. A central portion of the frame 34 is connected to a screw shaft 40 arranged in the vertical direction. The height of the cutter unit 36 can be adjusted by turning a nut 42 connected to the frame 34 and screwed onto the screw shaft 40. Thereby, the cutting positions of the first cutting blade 24 and the second cutting blade 26 with respect to the horizontal reference plane h can be adjusted, and the position of the cutting line c that cuts the bevel 132 can be adjusted.

  The round bar 22 is integrally connected to the workpiece positioning guide 20 via a frame, and the workpiece positioning guide 20 and the round bar 22 are configured to be lifted and lowered by a mechanism similar to the lifting mechanism that lifts and lowers the frame 34. . Thereby, the relative heights of the workpiece positioning guide 20 and the round bar 22 with respect to the first cutting blade 24 and the second cutting blade 26 can be adjusted.

  The workpiece w after the bevel 132 has been cut is conveyed to the kappa removal portion C. 8 and 9 show the kappa removal portion C. FIG. FIG. 8 is a view as seen from the front side of the automation apparatus 10, and FIG. 9 (A) is a view as seen from the back side. Hereinafter, the configuration of the kappa removal portion C will be described. A tip portion 44 a of the first round bar 44 is disposed above the downstream portion of the second cutting blade 26 in the transport direction. The first round bar 44 is arranged along the direction of arrow a on the conveyance path of the workpiece w. The tip end portion 44a of the first round bar 44 is bent obliquely toward the workpiece conveyance path, and is disposed at a position inserted in a non-contact manner into the cutout portion 180c of the cone body 180 being conveyed. In the workpiece w being conveyed, the tip portion 44a of the first round bar 44 is pierced between the position indicated by the circle d in FIG.

  A round bar 46 is connected to the second half of the first round bar 44 in an oblique direction. The first round bar 44 and the round bar 46 form a widening forming body 48 that widens in the vertical direction. The puncture hole formed in the workpiece w by the first round bar 44 is enlarged in the vertical direction by the widening formation body 48 as the workpiece w is conveyed. Thus, the rib 118 and the sternum 128 begin to separate at the cutting line b in FIG.

  A round bar 50 is connected to the frame 54 via a support bar 52 above the widening body 48. The round bar 50 is directed in the direction of the arrow a, and is arranged in parallel with the first round bar 44 at a position spaced from the first round bar 44. The upstream end portion 50a of the round bar 50 is inclined obliquely upward and toward the front side with respect to the conveyance path of the workpiece w.

The second round bar 56 has an action of pushing down the neck n directed toward the back side by the round bar 50. Therefore, the neck portion n is pushed downward while passing between the second round bar 56 and the fourth round bar 66. Therefore, the workpiece w is gradually separated from the carcass main body 142 with the neck and the kappa 120 fixed to the cone 18.

  A third round bar 60 is disposed above the second round bar 56 via a support bar 62. The third round bar 60 is arranged in the direction of arrow a. Above the first round bar 44, the first round bar 44 is arranged in parallel with the first round bar 44 at a constant interval. The distance between the first round bar 44 and the third round bar 60 is such that the pair of scapulas 126 attached to the kappa 120 can enter. While the neck n is pushed down by the second round bar 56, the brace 120 is fixed to the cone 18, and the scapula 126 associated with the brace 120 is between the first round bar 44 and the third round bar 60. It will be in the state caught on the stick | rod 44. FIG.

  The third round bar 60 presses the scapula 124 and the clavicle 122 so that the scapula 124 and the like do not go to the neck side to prevent breakage. With the above-described configuration and the conveyance of the cone 18, the workpiece w is peeled off by the carcass body 142 with the neck and the knot 120 along the cutting line b in FIG. 11.

  The carcass main body 142 with the neck portion thus separated from the kappa 120 falls onto the discharge chute 64 and is discharged. The kappa 120 is fixed to the cone 18 and conveyed in the direction of arrow a. As shown in FIG. 1, the end of the guide rail 28 is located above the drive sprocket 14. Here, when the cam 190 is released from the press of the guide rail 28, the movable arm 186 moves backward, and the kappa 120 is released from the fixation of the cone 18. By reversing the cone 18 above the drive sprocket 14, the kappa 120 falls onto the kappa discharge conveyor 70 provided below the drive sprocket 14 and is carried out. The cone 18 is conveyed while being inverted on the return path of the endless chain 12, and returns to the workpiece input unit A.

  FIG. 10 shows the carcass body 142 with the neck, the knot 120 and the bevel 132 separated by the automatic deboning apparatus 10. The kappa 120 is accompanied by a clavicle 122, a heel bone 124 and a scapula 126. The carcass body 142 with the neck and the kappa 120 remove the attached meat manually, the removed meat is used for food, and the remaining skeleton is used for chicken broth soup and the like. The bean 132 is used as a raw material for glucosamine or the like that is tasted as a yakitori or is said to be effective for osteoarthritis and rheumatism.

  According to the present embodiment, when the workpiece w is inserted into the cone 18 in the workpiece insertion portion A, the upper surface of the frame 20 arranged in the horizontal direction is set as the horizontal reference plane h, and the sternum ridge 130 is applied to the frame 20 In addition, the workpiece w can be positioned by applying the bevel 132 to the round bar 22 arranged in the horizontal direction, and the workpiece w can be moved in the horizontal direction while being positioned toward the bevel cut portion B. In addition, the first cutting blade 24 and the second cutting blade 26 are mounted on the cutter unit 36 so that the height of the cutter unit 36 can be adjusted, thereby adjusting the relative height between the horizontal reference plane h and the round bar 22. it can. Therefore, the cutting line c1 (see FIG. 11) of the bevel 132 can be adjusted to a desired position in the vertical direction.

  Further, on the upstream side of the first cutting blade 24, the cam 190 is pushed down by the guide rail 28, and the sternum ridge 130 of the work w is sandwiched between the movable arm 186 and the fixed arm 184, so that the sternum ridge 130 is securely fixed at a predetermined position. it can. Thereby, the cutting line c1 can be set to a desired position. Furthermore, the holding force of the sternum ridge 130 can be increased by making the upper end of the presser bar 30 of the movable arm 186 L-shaped. Moreover, the holding | maintenance of the workpiece | work w can be stabilized by making the contact surface 180a of the cone main body 180 which contacts the workpiece | work w into a plane. Further, since the lower step plane 180b is formed below the contact surface 180a, the round bar 22 and the second cutting blade 26 can be disposed close to the cone body 180.

  In addition, the boundary of the bevel 132 in the sternum crest 130 is shown by the line c1 of FIG. In this embodiment, since the 1st cutting blade 24 is arrange | positioned so that it may have angle (theta) (15-20 degrees) with respect to the horizontal surface H, the bevel 132 can be cut | disconnected by the line c1. Therefore, the volume of the bevel 132 to be cut can be increased to the maximum. Further, the first cutting blade 24 has a trapezoidal plate shape, and the blade 24a gradually approaches the bevel 132 from the front side of the paper surface in FIG. 6 and cuts the bevel 132 in the horizontal direction by the blade 24a. Only the bevel 132 can be cut, and the inner branch bone 144 adjacent to the bevel 132 is not cut. As a result, the inner branch bone 144 is not mixed into the bevel 132 after cutting, and therefore, the removal operation of the inner branch bone 144 is not required.

  Since the second cutting blade 26 is arranged in the vertical direction, that is, in the axial direction of the bevel 132, the cutting edge can be inserted into the membrane 146 without damaging the bevel 132. Moreover, the 2nd cutting blade 26 can cut down the film | membrane 146 automatically by conveyance of the workpiece | work w by making a wedge shape. Further, the bevel 132 is sandwiched between the second cutting blade 26 and the presser bar 30, and the bevel 132 is held on the outer surface of the second cutting blade 26 for a while, whereby the bevel 132 is pulled to the work body side through the film 146. Can be prevented. Thereby, the bevel 132 can be completely separated from the work body.

  In this way, in the bevel cut section B, the separation process of the bevel 132 can be automated, and the working time and personnel required for the work can be greatly reduced as compared with the manual work. Further, since a driving device is not required other than the conveying device for the cone 18, a control device for controlling the driving device is not required, and the device configuration can be simplified and reduced in cost.

  In the kappa removal portion C, the distal end portion 44a is disposed close to the cone main body 180 so that the distal end portion 44a of the first round bar 44 is disposed in the cutout portion 180c formed at the upper end of the cone main body 180. The first round bar 44 can be reliably pierced into a portion (circle d in FIG. 11) between the ostial bone 124 and the scapula 126 of the work w.

  Further, the neck n of the work w is directed from the conveyance path to the back side by the round bar 50, and the piercing hole of the first round bar 44 is widened by the widening formation body 48 following the first round bar 44, whereby the rib of the work w is obtained. By separating 118 and the sternum crest 130 and pushing down the neck n with the second round bar 56, the separation of the carcass body 142 with the neck and the kappa 120 can be started. Further, while the neck n is sandwiched between the second round bar 56 and the fourth round bar 66, the neck n is continuously pushed down, the scapula 126 is sandwiched between the first round bar 44 and the third round bar 60, and By holding the scapula 124 and the clavicle 122 on the side of the cone 18 with the third round bar 60, the skeleton carcass 142 with the neck and the kataka 120 can be reliably and easily separated while fixing the kataka 120 to the cone 18.

  Thus, the separation process of the carcass main body 142 with the neck and the kappa 120 can be automated even in the kappa removal part C. For this reason, it is possible to greatly reduce the work time and personnel required for the work as compared with the work by hand. Further, since a driving device is not required other than the conveying device for the cone 18, a control device for controlling the driving device is not required, and the device configuration can be simplified and reduced in cost.

  Since the bevel separation and the kappa separation can be automated simultaneously with a single device by the automation device 10 of the present embodiment, the work time can be greatly shortened and the efficiency can be improved compared to the manual work. For example, if the automatic deboning apparatus 10 is used, 4,500 birds can be processed in one hour. If this is done manually, at least two people are required. Furthermore, no drive device is required other than the drive device for driving the chain 12. Therefore, the power can be minimized, and a control device or the like is not required, and the device configuration can be simplified and reduced in cost.

  According to the present invention, the cutting and separating process of the thoracic skeleton (kappa) from the carcass (gara) with the neck can be automated by the machine, so that the work process can be made more efficient than the manual work.
