    1/28 “METHOD AND DEVICE FOR BONING A BONE LEG” Technical Field [0001] The present invention relates to a method and device for boning a bone leg of a livestock carcass, eg a bone leg of a carcass poultry, in which the process of making an incision for meat separation is automated.
    Fundamentals of the Technique [0002] In recent years, the cultivation and slaughter of birds and animals has been conducted on a large scale in response to increased demand for them. Thus, it is desired to fully automate each step of the process.
    [0003] Slaughter of a poultry carcass from livestock carcasses, can be divided into two main stages. One is a first slaughter step in which killing in cold blood, plucking and cleaning the carcass is carried out. The other is a second slaughter stage in which, after cooling the carcass having been processed in the first slaughtering stage, the carcass is divided and boned by each section of the same in order to produce carcass meat and by-products which are then packaged and stored .
    [0004] In the first slaughter stage, killing in cold blood, plucking and cleaning the carcass is automated and requires almost no manual work between the stages. In the second slaughter stage, separating the upper and lower portions of the carcass, separating each portion such as leg meat and breast meat and boning the separate portions are increasingly automated. For this reason, slaughter processing is increasingly automated and thus the yield rate is improving in the same way as the manual case.
    [0005] Patent Document 1 proposes to automate an incision step that is necessary as a preceding step prior to the boning step by the boning unit. As described in Patent Document 1, many pieces of the bone leg are suspended from a fixation unit and transferred to an incision station, and stopped at the incision station to make an incision in the meat in a state that the bone leg is immobilized. At
    Petition 870180033021, of 04/24/2018, p. 8/43
    2/28 incision station, the bone leg is precisely positioned and secured so that an incision knife can be moved precisely along a surface of the bones. This achieves a higher rate of return.
    [0006] Patent Document 2 describes an automated meat separating means for separating leg-on-bone from livestock animals such as a chicken. This means holding the ankle of the leg with bone from a fixation unit and transferring the leg with bone. The medium stops at a plurality of workstations and advances intermittently between workstations. As shown in FIG. 9 of Patent Document 2, a displacement path of the fixing unit is formed in a circle. The number of workstations is arranged along this circular displacement path to conduct the incision step and the step of separating meat in which tendon is cut and the meat is removed.
    [0007] The tendon is cut using the means of a rounded cutting blade that is located in the vicinity of the leg meat transfer path and in the direction of a direction through the bone. The rounded cutting blade is moved close to the bone leg in order to cut the tendon of the bone. As shown in FIG. 10 of Patent Document 2, in the meat separation step, the leg meat is held in part of the bone by a pair of separators (pressure plates), and the leg meat is removed from the bone by lifting the fixation unit . By detecting the position of the femur end, a precise position at which the removal of the meat from the leg ends can be determined. The muscle at the end of the femur is cut so that the leg meat can be completely separated from a femur head.

    Summary of the Invention
    Technical problem
    Petition 870180033021, of 04/24/2018, p. 9/43
    3/28 [0011] In the incision device described in Patent Document 1, the incision is made by moving an incision knife unit including the incision knife and the drive unit in the vertical direction. Thus, this requires a large amount of energy to move the heavy incision knife unit and the displacement mechanism for the incision knife unit inevitably becomes large. In the case of using an air cylinder as the drive unit for the incision knife unit, the compressed air pressure must be substantially high to raise the incision knife unit to a prescribed height with high accuracy.
    [0012] According to Patent Document 1, the incision knife is moved along the inner curved surface of the leg bones with bone moving the incision knife from below the ankle to the end of the femur. However, with such a simple movement, the incision knife cannot reach the tendon firmly attached to the knee joint and thus it is difficult to smoothly separate the meat part from the bones. As a result, the yield rate is not improved.
    [0013] Additionally according to Patent Document 1, the incision device is arranged in the vicinity of the boning device body. The incision device is large, taking up a lot of space. As a result, the overall size of the boning device becomes very large as well.
    [0014] In the automated meat sorting medium described in Patent Document 2, the incision step is not specifically described. It is assumed that the incision step is performed manually by an operator. In the step of separating meat, in order to cut the tendon attached to the bones, the rounded cutting blades are moved along a complicated arc path on the flat two-dimensional surface to reach the tendon connection in order to cut the tendon attached to the bones. Thus, a control mechanism for moving rounded cutting blades inevitably becomes expensive.
    [0015] In view of the above problems, a first objective of the present invention is to achieve cost reduction by simplifying a mechanism for transferring the leg with bone and reducing the energy required in an automated bone deboning process
    Petition 870180033021, of 04/24/2018, p. 10/43
    4/28 leg with bone such as a livestock carcass.
    [0016] It is a second objective of the present invention to simplify and reduce the price of a cutting blade displacement mechanism in the process of moving the cutting blades to the bone leg to cut the bone leg.
    [0017] It is a third objective of the present invention to improve a meat yield in the step of making an automated incision, cutting firmly the tendon connected to the knee joint.
    Problem Solution [0018] To achieve the objectives, an aspect of the present invention is a method of boning a bone leg by means of a boning device. The method may include, but is not limited to, steps of: fixing the bone leg on an ankle of the same with a fixation unit; transfer the fixing unit intermittently between a plurality of workstations; and performing at each of the workstations at least one of an incision process of making an incision in the leg with bone longitudinally displacing a cutting blade along the bones and a meat separation process of separating a part of meat from the leg with bone from the bones lifting the bone leg relatively upwards while keeping the meat part down from the top by means of a meat separator and cutting a tendon with a cutting blade. The boning device may include: a lifting and lowering shaft whose lower end is connected to the fixing unit which has a lifting and lowering roller above the fixing unit; a lifting unit that is provided at each of the workstations and includes a drive motor, a threaded shaft connected to an output shaft of the drive motor and a lift and lower table that is threaded on the shaft thereof; and a travel path that is arranged between the workstations and tilts downwards in a transfer direction of the clamping unit. The process of making an incision or separating meat can be performed at one of the workstations by placing the lifting and lowering roller on the lifting and lowering table and lifting the leg with bone lifting the
    Petition 870180033021, of 04/24/2018, p. 11/43
    5/28 lifting and lowering table. The lowering and lifting roller can move in the underfoot travel path of the bone leg to transfer the clamping unit down from the workstation to a subsequent workstation.
    [0019] According to the method of boning, the incision step and the meat sorting step is performed by lifting the fixation unit on the workstation by means of the lifting unit. Using the weight of the bone leg itself, the lifting and lowering roller mounted on the lifting and lowering axis moves along the travel path so that the clamping unit is lowered while being transferred to the subsequent workstation .
    [0020] For this reason, it is possible to simplify the structures of the lifting unit and the transfer mechanism to transfer the bone leg between the work stations. It is also possible to achieve cost savings by reducing the energy required from the drive motor.
    [0021] Using the servomotor as the drive motor, the height of the clamping unit can be precisely controlled.
    [0022] In the boning method, the boning device can also include a rotating mechanism that is provided in at least one of the work stations having the cutting blade and rotates the lifting and lowering axis by an adjustment angle. The lifting and lowering axis can be rotated around an axis center of the same. The rotating mechanism rotates the lifting and lowering axis so that a part to be cut from the bone leg faces the cutting blade. The cutting blade is moved towards the part to be cut from the bone leg along a linear path to cut the part to be cut from the bone leg.
    [0023] By rotating the lifting and lowering axis so that the part to be cut faces the cutting blade, the cutting blade can be moved in the direction of the part to be cut along a linear path. As a result, the path of the cutting blade is simplified and thus the mechanism of displacement of the cutting blade
    Petition 870180033021, of 04/24/2018, p. 12/43
    6/28 cutting can be simplified and cheaper.
    [0024] In the boning method, the cutting blade can be a tendon cutting blade consisting of a rounded blade that is arranged in a horizontal direction. The tendon cutting blade is moved along the linear path towards the part to be cut from the bone leg. The tendon cutting blade cuts through a tendon that is attached to the bones.
    [0025] In the boning method, at least one of the workstations is an incision station in which the incision process is performed. The incision process may include, but is not limited to: an ossa-cruris incision step of making an incision from around the ankle to an upper part of the knee joint by raising the bone leg in relation to the top of the knee. cutting blade while moving the cutting blade along an internal curved surface of the bones; a knee joint incision step of making a tendon incision by temporarily rotating the lifting and lowering axis so that the cutting blade is moved around a knee joint tendon connection of the internal curved surface of the bones and then reversing the fixation unit to return the internal curved surface of the bones to face the cutting blade, and an incision step in the femur to make an incision from the bottom of the knee joint to an end of the femur by raising the leg with bone relatively upwards relative to the cutting blade while moving the cutting blade along the internal curved surface of the bones.
    [0026] As described above, when the cutting blade reaches the knee joint while the bone leg is raised, the fixation unit is rotated by the adjustment angle so that the cutting blade is moved around the tendon connection of the knee joint from the internal curved surface of the bones to cut the tendon. Thus, the tendon firmly attached to the knee joint can be securely separated. As a result, the step of separating meat can be smoothly performed, and thus the yield of the meat is improved.
    [0027] The fixing unit alone is lifted without moving the unit with the
    Petition 870180033021, of 04/24/2018, p. 13/43
    7/28 incision knife. Thus, the lift unit for moving the heavy incision knife unit upward can be removed. According to the method of boning the aspect of the present invention, the light fixation unit is raised instead of the heavy incision knife unit. The incision station can be simplified and made at low cost and the positioning of the leg with bone at the height of adjustment can be performed in height accuracy.
    [0028] In the incision step, a lower end of the leg with bone is detected while the leg with bone is raised and a total length of the bones of the leg with bone is obtained based on a height at which the detection is performed and a amount of lifting the bone leg when the lower end of the bone leg is detected. A lifting amount of the fixing unit in the meat separation process with respect to a meat separator keeping the meat part down, is adjusted according to the total length of the bone leg having been obtained.
    [0029] Thus, the bone part and the meat part can be firmly separated in the final meat separation process by adjusting the lifting amount of the clamping unit according to individual differences in work length.
    [0030] Another aspect of the present invention is a device for boning a bone leg, which can be directly used to implement the method of the first aspect of the present invention. The device can include, but is not limited to: a plurality of workstations in which at least one incision process of making an incision in the bone leg longitudinally moving a cutting blade along the bones and a process of separating meat separating a portion of meat from the bone leg from the bones by lifting the bone leg relatively upwards while holding the meat portion down from the top by means of a meat separator and cutting a tendon with a cutting blade is performed; a fixation unit that fixes the leg with bone on the ankle; a transfer mechanism that intermittently transfers the clamping unit from one workstation to another; an axis of
    Petition 870180033021, of 04/24/2018, p. 14/43
    8/28 lifting and lowering whose lower end is connected to the fixing unit which has a lifting and lowering roller above the fixing unit; a lifting unit that is provided at each of the workstations and comprises a drive motor, a threaded shaft connected to an output shaft of the drive motor and a lifting and lowering table threaded mounted on the threaded shaft; and a travel path that is arranged between the workstations and tilts downwards in a transfer direction of the clamping unit. The process of making incisions or separating meat is carried out at one of the workstations by placing the lifting and lowering roller on the lifting and lowering table and lifting the leg with bone by lifting the lifting and lowering table. The lifting and lowering roller moves on a weighted leg travel path to transfer the clamping unit down from one of the workstations to a subsequent workstation.
    [0031] As described above, the fixation unit is lifted by means of the lifting unit to perform the incision step and the meat separation step. Using the bone leg's own weight, the lifting and lowering roller mounted on the lifting and lowering axis moves along a travel path so that the clamping unit is lowered while being transferred to the subsequent workstation .
    [0032] For this reason, it is possible to simplify the structures of the lifting unit and the transfer mechanism to transfer the bone leg between the work stations. It is also possible to achieve cost savings by reducing the energy required from the drive motor. Using the servomotor as the drive motor, the height of the clamping unit can be precisely controlled. [0033] The boning device may also include a rotating mechanism that is provided in at least one of the workstations having the cutting blade and rotates the lifting and lowering axis which is rotatable around a center by an adjustment angle. axis. The rotating mechanism rotates the lifting and lowering axis so that a part of the leg to be cut with
    Petition 870180033021, of 04/24/2018, p. 15/43
    9/28 bone face the cutting blade and the cutting blade is moved towards the part to be cut from the bone leg along a linear path to cut the part to be cut from the bone leg. By rotating the lifting and lowering axis so that the part to be cut faces the cutting blade, the cutting blade can be moved towards the part to be cut along a linear path. As a result, the path of the cutting blade is simplified and thus the mechanism for moving the cutting blade can be simplified and made cheaper.
    [0034] In the boning device, the lifting and lowering axis can include a guide bar that is attached to the transfer mechanism, a sliding support that slides up and down along the guide bar and a rotation axis that it is rotatably arranged inside the sliding support and whose lower end is connected to the fixing unit. The rotating mechanism includes an oscillating roller attached to the axis of rotation, a cam member that pushes the oscillating roller when the clamping unit is raised and the cutting blade is moved close to a knee joint so that the axis of rotation rotates by an adjustment angle and a spring member that returns the oscillating roller to an original position when the clamping unit is still raised and the oscillating roller moves away from the cam member.
    [0035] The lifting and lowering axis is configured as described above and the oscillating roller connected to the rotation axis is pushed by the cam member provided in the workstation. Thus, the rotating mechanism can be configured by the machine parts only and there is no need for a separate drive unit or a complicated electronic control unit. As a result, it is possible to reduce the cost of the rotating mechanism. Without the electronic control unit, the device is less prone to failure, resulting in improved device reliability.
    [0036] In the workstation in which the meat sorting step is performed, the cutting blade can be a tendon cutting blade consisting of a rounded blade that is arranged in a horizontal direction. The cutting blade is moved towards the part to be cut from the bone leg along a linear path
    Petition 870180033021, of 04/24/2018, p. 16/43
    10/28 to cut the part to be cut from the bone leg. The tendon cutting blade cuts a tendon that is attached to the bones. Thus, the displacement mechanism of the tendon cutting blade can be simplified and made cheaper.
    [0037] In the boning device, at least one of the workstations can be an incision station that includes the cutting blade capable of moving towards and away from the bone leg, a plate maintaining a position that is willing to stay facing a direction of movement of the cutting blade and a pressure member that presses a flat side of the leg with bone against the plate while maintaining position. The rotating mechanism rotates the lifting and lowering axis by an angle prescribed in the middle of the upward movement. The cutting blade is inserted close to the ankle of the bone leg so that a state that the pressure member presses the bone leg against the plate maintaining position and the fixing unit is raised so that the cutting blade moves along of an internal curved surface of the bones to make the incision. When the cutting blade is close to the knee joint, the rotating mechanism rotates the lifting and lowering axis temporarily so that the cutting blade is moved around a knee joint tendon connection from the inner curved surface to cut the tendon.
    [0038] As described above, when the cutting blade reaches the knee joint while the bone leg is raised, the fixation unit is rotated by an adjustment angle by the rotating mechanism so that the cutting blade is moved around of a tendon connection of the knee joint from the internal curved surface of the bones to cut the tendon. Thus, the tendon firmly attached to the knee joint can be securely separated. As a result, the following meat separation step can be smoothly performed, and thus the yield of the meat is improved. By means of the rotating mechanism, the fixation unit can rotate precisely through the adjustment angle to cut the tendon connected to the knee joint.
    [0039] The fixation unit is lifted without moving the unit with the incision knife. So the unit raised to move the incision knife unit
    Petition 870180033021, of 04/24/2018, p. 17/43
    Heavy 11/28 upwards is not necessary. According to the boning device of the other aspect of the present invention, the light clamping unit is raised instead of the heavy-duty knife unit. The incision station can be simplified and made at low cost and the positioning of the bone leg at the height of adjustment can be performed with high precision.
    [0040] The boning device of the other aspect of the present invention may further include an entry station comprising: a rotating member which is arranged in the vicinity of an entry position into which the bone leg is entered and is rotated around a central geometric axis thereof; a plurality of suspension supports each of which has a concave part in which the bone leg is suspended by the ankle; and a pusher that pushes the bone leg into the fixation unit when the bone leg suspended from the suspension bracket comes to an opposite position from the entry position in order to load the bone leg into the fixation unit.
    [0041] By synchronizing the movement of the suspension brackets and the movement of the fixation unit, the bone leg is loaded securely from the suspension bracket to the fixation unit can be securely. Loading of the bone leg from the suspension bracket to the fixation unit is automated. It is also possible to simplify the structure of the entrance station where the bone leg is kept in the fixation unit. Alternatively, the bone leg can be maintained on the suspension bracket manually by an operator, or automatically by loading the bone leg via a conveyor loading the bone leg to the entrance station.
    [0042] The boning device can also include: a brake shoe that is mounted on a base part supporting the guide bar and is rotatably supported on a geometric axis of the axis thereof; a spring member that applies spring force to the brake shoe in a direction of pushing the brake shoe in the direction of the axis of rotation; and a brake release rail that is arranged in a direction of transfer of the brake shoe between workstations and is configured to keep the brake shoe away from the axis of rotation against the force of the
    Petition 870180033021, of 04/24/2018, p. 18/43
    12/28 spring of the spring member.
    [0043] In this way, the brake shoe is pressed against the axis of rotation while the axis of rotation is at the workstation in order to prevent the axis of rotation from falling. While the axis of rotation is moved between stations, the brake shoe is released from the axis of rotation to allow the axis of rotation to move downwards.
    Advantageous Effects of the Invention [0044] In accordance with the method of boning the aspect of the present invention, the method includes the steps of: fixing the leg with bone on an ankle of the same by a fixation unit; transfer the fixing unit intermittently between a plurality of workstations; and performing at least one of an incision step of making an incision in the leg with bone longitudinally moving a cutting blade along the bones and a step of separating meat from separating a part of the leg meat with bone from the bones by lifting the leg with bone up relatively while keeping the top meat part down by means of a meat separator and cutting a tendon with a cutting blade. The boning device may include: a lifting and lowering shaft whose lower end is connected to the fixing unit and to which it has a lifting and lowering roller above the fixing unit; a lifting unit that is provided at each of the workstations and includes a drive motor, a threaded shaft connected to an output shaft of the drive motor and a lifting and lowering table threaded mounted on the threaded shaft; and a travel path that is arranged between the workstations and tilted downwards in a transfer direction of the clamping unit. The incision step or meat separation process can be performed at one of the workstations by placing the lifting and lowering roller on the lifting and lowering table and lifting the bone leg by lifting the lifting and lowering table. The lifting and lowering roller can travel on the displacement path under bone leg weight to transfer the clamping unit down from a workstation
    Petition 870180033021, of 04/24/2018, p. 19/43
    13/28 for a subsequent workstation. As a result, the lifting unit and the transfer mechanism between workstations can be simplified and the energy required from the drive unit can be reduced, thereby achieving cost reduction.
    [0045] According to the boning device of the other aspect of the present invention, the device includes a plurality of workstations in which at least one of an incision process of making an incision in the leg with bone longitudinally moving a blade of cutting along the bones and a process of separating meat from separating a piece of meat from the bone leg from the bones by lifting the bone leg relatively upwards while holding the meat part down from above by means of a meat separator and cutting a tendon with a cutting blade is carried out; a fixation unit fixes the leg with bone on the ankle; a transfer mechanism that intermittently transfers the clamping unit from one workstation to another; a lifting and lowering shaft whose lower end is connected to the fixing unit and which has a lifting and lowering roller above the fixing unit; a lifting unit that is provided at each of the workstations and comprises a drive motor, a threaded shaft connected to an output shaft of the drive motor and a lifting and lowering table threaded mounted on the threaded shaft; and a travel path that is arranged between the workstations and tilted downwards in a transfer direction of the clamping unit. The process of making an incision or separating meat is carried out at one of the workstations by placing the lifting and lowering roller on the lifting and lowering table and lifting the bone leg by lifting the lifting and lowering table. The lifting and lowering roller moves along the underweight travel path of the bone leg to transfer the clamping unit down from one workstation to a subsequent workstation. Thus, the same function effect as the method of the first aspect of the present invention can be achieved.

    Description of Modalities [0059] A preferred embodiment of the present invention will now be described in detail with reference to the accompanying drawings. It is intended, however,
    Petition 870180033021, of 04/24/2018, p. 21/43
    15/28 that unless specifically specified, dimensions, materials, shape, their relative and similar positions are to be construed as illustrative and not limiting the scope of the present invention.
    [0060] A first preferred embodiment is explained with reference to FIG. 1 to FIG 10. In the first preferred embodiment, the device and method of the present invention are applied to a one-leg boner with bone from a livestock carcass. An overall structure of the boning process is explained with reference to FIG. 1 and FIG. 2A through FIG. 2D. As shown in FIG. 2A, the leg with bone from the livestock carcass, here called “work w” consists of a part of bone including an ankle f, an ossa-cruris (leg bone of the lower thigh) k, a femur j and a part of meat m involving the bone part. The ossacruris k and the femur are connected by a knee joint.
    [0061] As shown in FIG. 1 and FIG. 4, the boning device 10 has work stations arranged in a circle. At work stations, work entry for final separation of the meat part is performed. Work w is suspended from a clamping unit 12. Clamping unit 12 is connected to a circular transfer member 78 via a guide bar 72 of the lifting and lowering axis 70. Circular transfer member 78 rotates intermittently in the direction of an arrow a. The clamping unit 12 moves along a circular path around a center of rotation O from one workstation to another workstation and stops at each workstation. A servomotor 104 is provided to raise and lower the clamping unit 12 at each workstation.
    [0062] FIG. 3 shows a circular support beam 11 arranged in an upper part and a lower part of the boning device 10. The servomotor 104 and a support frame 13 are attached to the support beam 11. The support frame 13 supports an external panel 15 and the like constituting a travel path 94. The support beam 11 is not shown in FIG. 5.
    [0063] FIG. 1 is an illustration of a boning device for a left leg. The bone-in-bone boning device has first to tenth
    Petition 870180033021, of 04/24/2018, p. 22/43
    16/28 workstations arranged in the direction of the arrow in order. In contrast, a boning device for a right leg, the first to tenth workstations are arranged in this order in the direction of arrow b.
    [0064] Work w is loaded on the clamping unit 12 via an input unit 14 provided on the first workstation, eg input station. Inlet unit 14 includes a pivot member 16, four suspension brackets 18 and a pusher 20. Pivot member 16 intermittently rotates about a vertical axis 16a. The suspension supports 18 arranged around the rotation member 16 at equal intervals. The pusher 20 is arranged in such a place to face the fixing unit 12. The rotating member 16 rotates intermittently at a 90 degree angle, rotating each time in synchronization with the intermittent forward movement of the fixing unit 12. Each of the suspension brackets 18 has a concave part 18a that opens outwards. Work w is suspended in the concave part 18a.
    [0065] Work w can be maintained on the concave part 18a of the suspension bracket 18 manually by an operator or automatically loading the work w on the concave part 18a by means of a conveyor loading the work w from the first workstation, eg the entrance station and a loading unit not shown loading the work automatically in the concave part 18a.
    [0066] The suspension bracket 18 with work w is rotated intermittently and stopped in position to face the clamping unit 12. In position, pusher 20 pushes work w to clamping unit 12 in order to load the work for the clamping unit 12.
    [0067] As shown in FIG. 4, the fixing unit 12 is connected to the lower end of the rotation axis 76 of the lifting and lowering axis 70. The fixing unit 12 includes a fixing body 122 having a groove 124 and a mandrel 126. The ankle f of the work w is inserted into slot 124. Slot 124 can be opened or closed by chuck 126. Chuck 126 is automatically operated by a control unit not shown.

    17/28 [0068] After the work w is loaded on the clamping unit 12, the chuck 126 is automatically operated to close the slot opening 124. Then, the clamping unit 12 advances to the second workstation, p eg incision station. At the second workstation, an incision step is performed. In the incision step, an incision knife is inserted into the work w and then moved along the bone longitudinally raising the work w in order to cut the meat part m. The total length of work w is measured while making the incision.
    [0069] Next, the fixing unit 12 is transferred to the third workstation. At the third workstation, a pair of rounded cutting blades 22 is positioned with surfaces thereof arranged in a horizontal direction. The rounded cutting blades 22 approximate the work w suspended in the fixing unit 12 in order to cut the tendon connected to the ankle f. The clamping unit 12 with work w is transferred to the fourth workstation. In the fourth workstation, a meat separator 24 including a stationary separator 26 and a movable separator 28 is provided. The mobile separator 28 is movable in the direction to move near or far from the stationary separator 26. The meat portion m is held between the stationary separator 26 and the movable separator 28. A rounded cutting blade 30 from the fourth workstation cuts a small bone muscle while the stationary separator 26 and the movable separator 28 keep the meat part m between them down and the fixing unit 12 is pulled upwards.
    [0070] The small bone muscle here refers to the muscle that is adhered to a small bone that is adhered to k ossa-cruris along a side surface of the same and is a size of a toothpick and is located along of a line extending from the small bone (ankle side). If the small bone muscle has already been cut before the fourth workstation in which the meat part m is removed, the small bone may fall from the k bone, resulting in bone displacement in the middle part (knee joint h) between ossa-cruris keo femur j. Thus, the small bone muscle is intentionally left uncut in the third
    Petition 870180033021, of 04/24/2018, p. 24/43
    18/28 workstation. The small bone muscle is cut after removing the meat part at the fourth workstation.
    [0071] Work w is transferred to a fifth workstation. At the fifth workstation, work w is held down by a meat separator 32 having a stationary separator 34 and a movable separator 36, while the work is raised to expose the knee joint h. Work w is then transferred to the sixth workstation. On the way to the sixth workstation, the clamping unit 12 is lowered. Once the work w arrives at the sixth workstation, the clamping unit 12 is raised. While lifting the fixation unit 12, the location of the knee joint h is measured by a measurement unit 38 and x-muscle is cut by a cutter 40.
    [0072] The x-muscle is the muscle at the knee joint h. The x-muscle must be cut to remove the meat part m from the knee joint h. The x-muscle is cut while work w is transferred to a seventh workstation after the knee joint location is measured at the sixth workstation.
    [0073] Work w is then transferred to a seventh workstation. At the seventh workstation, the muscle attached to the knee joint is cut. The lifting amount of work w is adjusted based on the location of the knee joint h measured at the sixth workstation. The work w is lifted by the adjusted lift amount while the meat part m is held down by a meat separator 42 consisting of a stationary separator 44 and a movable separator 46. Therefore, the knee joint h is exposed. A set of three rounded cutting blades 48 cuts the muscle attached to the exposed knee joint h.
    [0074] Work w is transferred to an eighth workstation. At the eighth station and work, work w is lifted while meat part m is held down by a meat separator 50 consisting of a stationary separator 54 and a movable separator 56. The lift quantity here is adjusted based on location knee joint h measured at the sixth workstation. Then, a set of three rounded cutting blades 56 cuts beam just below
    Petition 870180033021, of 04/24/2018, p. 25/43
    19/28 of the knee joint h.
    [0075] Work w is transferred to a ninth workstation. A final separation of the meat part m is carried out at the ninth workstation. At the ninth workstation, the work w is lifted while the meat part m is held down by a meat separator 58 consisting of a stationary separator 60 and a movable separator 62. Therefore, the meat part m is separated from the femur j. The fixation unit 12 is rotated 90 degrees and then reversed 90 degrees so that a rounded cutting blade 64 cuts the tendon attached to one end of a femur head bone j during the rotation and reversal of the fixation unit 12. For therefore, the meat part m is removed from the bone part and the removed meat part m falls in an ejection path not shown so as to be ejected.
    [0076] At the tenth workstation, the chuck 126 of the clamping unit 12 is activated to open the clamping unit 12, thus allowing the part of the bone from which the meat part m has been removed to fall from the clamping unit 12. The bone part is left in a different ejection path than for the meat part then ejected.
    [0077] Now, the incision process carried out at the second workstation, eg incision station, is explained in detail with reference to FIG. 3 through FIG. 10. FIG. 4 illustrates a state where the clamping unit 12 with work w suspended in it is in the second work station.
    [0078] As shown in FIG. 4 through FIG. 6, the lifting and lowering axis 70 includes a pair of guide bars 72 arranged in a vertical direction, a sliding support 74 which is slidable along the guide bars 72 and a rotating axis 76 which is coaxially arranged within the support sliding 74. The fixing unit 12 is mounted on a lower end of the rotation axis 76. Upper ends of the guide bars 72 are attached to the circular transfer member 78. The circular transfer member 78 is rotated continuously by an adjustment angle by a drive unit not shown. Lower ends of the guide bars 72 are fixed to a base
    Petition 870180033021, of 04/24/2018, p. 26/43
    20/28 circular 90 through a fixing member 88. The circular base 90 is not shown in FIG. 4 and shown in FIG. 5 and FIG. 6.
    [0079] The first to the tenth workstations are arranged at equal intervals around the center of rotation o. Thus, the clamping unit 12 is transferred from one station to another station for each rotational movement. FIG. 4 shows only a clamping unit 12. In the current device, a plurality of lifting and lowering axes 70 are attached to the circular transfer member 78 so that it has a clamping unit 12 at each of the workstations.
    [0080] The axis of rotation 76 has a spiral spring 80 wound at the upper end. Near the spiral spring 80, an oscillating roller 84 is mounted on the axis of rotation 76 by means of an arm. An end of the spiral spring 80 is attached to a metal fixing member 86 which is integrally formed with the sliding support 74. The force of the spiral spring spring 80 is applied to the axis of rotation 76 around the axis.
    [0081] A raise and lower roller 92 is mounted on the sliding support 74 below the oscillating roller 84. The travel path 94 is arranged between the work stations. The displacement path 94 has a guide channel in which the lifting and lowering roller 92 moves. When transferring the clamping unit 12 from one workstation to another, a vertical position of the clamping unit 12 can be controlled by moving the lifting and lowering roller 92 on the displacement path 94.
    [0082] As shown in FIG. 7, a shaft bearing 95 is provided on a top surface of the circular base 90 and a base portion 96 and a brake shoe 96a integrally formed with the base portion 96 are mounted on the shaft bearing 95 rotatably about one pin 98. The brake shoe 96a is directed slightly upward. A spiral spring 100 is mounted on the base part 96. The spiral spring 100 applies spring force in the direction of pushing the brake shoe 96a towards an external surface of the axis of rotation 76. Therefore, the axis of rotation 76 is prevented from falling when the fixing unit 12 is
    Petition 870180033021, of 04/24/2018, p. 27/43
    21/28 at each of the workstations.
    [0083] As shown in FIG. 4, work w is picked up at each workstation mainly by means using a servomotor 104 as a drive unit. Servomotor 104 is provided at each workstation. An output shaft of the servomotor 104 is coupled to a threaded shaft 106. A lifting and lowering block 108 is threadedly mounted on threaded shaft 106. Rotating the threaded shaft 106 increases the lifting and lowering block 108.
    [0084] At each station, the lifting and lowering roller 92 moves on the travel path 94. Once the lifting and lowering roller 92 reaches the top surface of the lifting and lowering block108, the servomotor 104 is driven to lift the lifting and lowering block 108 as well as the lifting and lowering roller 92. When the lifting and lowering roller 92 is raised, the rotation axis 76 is raised as well as the slide holder 74 being integral with the lifting roller and lowering 92, thus lifting the work w. The lifting amount of the lifting and lowering block 108 is adjusted based on the rotation speed of the servomotor 104.
    [0085] During the lifting of the axis of rotation 76, the brake shoe 96a is pressed against the axis of rotation 76 to prevent the axis of rotation 76 from falling. A roller 102 is provided on the top surface of the base part 96. As illustrated in FIG. 3, a guide rail 110 is attached to the support beam 11 below the area where the travel path 94 is arranged downward in the direction of the arrow a. In this area, when the lift and lower roller 92 moves on the travel path 94, the roller 102 is on the guide rail 110 so that the guide rail 110 pushes the base part 96 downwards. part of the base 96, the brake shoe 96a moves away from the axis of rotation to release the axis of rotation 76 downwards. For this reason, the lifting and lowering roller 92 moves downward on the travel path 94.
    [0086] As FIG. 3 shows, the support beam 11 is attached to the guide rail 110
    Petition 870180033021, of 04/24/2018, p. 28/43
    22/28 under travel path 94 in the area where travel path 94 is laid down with respect to the transfer direction of the clamping unit 12. Using the guide rails 110 provided at work stations, the brake shoes 96a move away from the axis of rotation 76 before the lift and lower roller 92 enters the travel path 94. Therefore, the axis of rotation 76 is released to fall and thus the clamping unit 12 can be moved to low.
    [0087] The process of making incisions at the second workstation, eg the incision station is explained with reference to FIG. 8 through FIG. 10. In FIG. 8 and FIG. 9, a plate holding position 112 with a flat surface is arranged in a vertical direction such as to traverse the work transfer path w. The work w (left leg) suspended from the fixing unit 12 is transferred from the first work station (entry station) and stopped in contact with the plate maintaining position 112. In case of transferring the right leg, the curved profile of the part of the bone is axially symmetrical to work w (left leg) in FIG. 8.
    [0088] On the right side of the plate maintaining position 112, a housing 116 fixed to a base 114 is provided. An air cylinder 118 is housed in housing 116. A right pusher 130 is connected to a piston rod 118a of air cylinder 118. On the left side of the plate maintaining position 112, a housing 134 fixed to a base 132 is provided. An air cylinder 138 is housed in housing 134. A left pusher 140 is connected to a piston rod 138a of air cylinder 138.
    [0089] Under the right pusher 130, a lower pusher 142 is provided. The lower pusher 142 is connected to a rotary shaft 144. An air cylinder not shown as a drive source, rotates the pivot shaft 144 to move the lower pusher 142 towards or away from work w. When the work w comes in contact with the plate maintaining position 112 and stopped, the right pusher 130, the left pusher 140 and the lower pusher 142 move in the direction of the work w. Work w is maintained from three directions by
    Petition 870180033021, of 04/24/2018, p. 29/43
    23/28 right pusher 130, left pusher 140 and lower pusher 142 and pressed against the plate maintaining position 112 and immobilized there.
    [0090] In FIG. 9, a plate holding position 146 is arranged in a vertical direction through the plate holding position 112. The plate holding 146 is connected to an arm 150 and is rotatable about the rotary axis 148. The arm 150 is driven by a drive unit 152 in the direction to rotate the rotary axis 148. When work w comes in contact with the plate holding position 112 and stopped there, the plate holding 146 is rotated to move closer to work w. One flat side of the work w is pressed by the plate holding 146 so as to press the other flat side of the work w against the plate holding position 112 and immobilizes the work w there.
    [0091] Below the right pusher 140, a measurement plate 154 is held at one end of a first arm 156. The first arm 156 is connected to a second arm 158. A branch arm 160 is integrally connected to a second arm 158. A connecting part of the second arm 158 and the branched arm 160 is rotatable about a rotary axis 162 arranged in the housing 172. Another end of the second arm 158 is connected to a piston rod 164a of an air cylinder 164 which is housed in a housing 172. Measuring plate 154 is movable in the direction of or away from work w via air cylinder 164.
    [0092] Below the right the fixation unit 12, an incision knife 168 is arranged in the work direction w. The incision knife 168 is capable of moving towards or away from work w by means of the drive unit not shown.
    [0093] As described above, after work w is stopped in contact with the plate maintaining position 112, the right pusher 130, the left pusher 140 and the lower pusher 142 move in the direction of work w in order to keep work w from starting from the three directions. At the same time, the plate holding 146 is rotated in the direction of work w so as to press the flat side of the work w against the plate holding position 112 and immobilize the work w there. Then the knife
    Petition 870180033021, of 04/24/2018, p. 30/43
    24/28 incision 168 is inserted close to the ankle of the work w and the work w is lifted by the fixation unit 12. Therefore, the incision knife 168 makes the incision along the internal curved surface of the bones in the direction of the arrow c in FIG. 8. The meat part m and the bones are separated.
    [0094] FIG. 4 illustrates a cam plate 180 on the outer panel 15 of the second work station (incision station). FIG. 10 illustrates a cam 170 with a curved cam surface 170a. As described last, the curved cam surface 170a is formed so that the oscillating roller 84 rotates by a degree of adjustment in contact with the curved cam surface 170a. A rotating mechanism 171 includes an oscillating roller 84, cam 170 and spiral spring 80.
    [0095] When the incision knife 168 reaches close to the knee joint h, the oscillating roller 84 contacts the cam surface 170a of the cam plate 170 so as to rotate the axis of rotation 76 through the adjustment angle D, eg 30 degrees. For this reason, the incision knife 168 follows the path indicated by the arrow d in FIG. 8. Specifically, the incision knife 168 moves along the posterior surface of the knee joint h to cut the tendon attached to the posterior surface.
    [0096] FIG. 10 illustrates the movement of the incision knife 168 as the clamping unit 12 lifts. the incision knife 168 moves in the order of S01 to S04. The incision knife 168 moves close to the knee joint in the order of S01 to S04. S01 of FIG. 10 shows the incision knife 168 when the oscillating roller 84 contacts the cam surface 170a. After the oscillating roller 84 touches the cam surface 170a, the axis of rotation 76 rotates to D degrees. S04 of FIG. 10 shows the incision knife 168 when the oscillating roller 84 is off the cam surface 170a as the clamping unit 12 is raised and the axis of rotation 76 makes a reverse rotation to its original position by the spring force of the spiral spring 80 .
    [0097] When the incision knife 168 reaches the underside of the knee joint h, the oscillating roller 84 goes out of the cam surface 170a. Therefore, the spring force of the spiral spring 80 rotates the axis of rotation 76 in the opposite direction to its original position. The incision knife 168 returns to the internal curved surface of the bones at the bottom of the knee joint h. So, work w is lowered so
    Petition 870180033021, of 04/24/2018, p. 31/43
    25/28 that the incision knife 168 make an incision along the internal curved surface of the bone part as indicated by the arrow and in order to cut the meat part m. [0098] FIG. 8 shows a non-contact sensor 166 at the bottom of housing 172. After maintaining work w against the plate maintaining position 112, measuring plate 154 moves in the direction of work w by driving air cylinder 164 and comes into contact with work w. In conjunction with lifting work w, measuring plate 154 moves forward while maintaining contact with work w. When the measuring plate 154 reaches the lower end of the work w, the branch arm 160 is closest to the non-contact sensor 166. The non-contact sensor 166 detects the moment when the branch arm 160 reaches the point closest to the non-contact sensor 166, eg measuring plate 154 is in contact with the lower end of the work w. The detected moment is sent to a working length measurement unit.
    [0099] The rotation speed of the servomotor 104 is detected by the encoder 176. The detected value is sent to the measuring unit of working length 174. The height of the lifting and lowering roller 92 (lifting stroke) can be determined with based on the detection value. The total length of the working bones w is obtained based on the height of the lifting and lowering roller 92 at the moment when the branched arm 160 is detected by the non-contact sensor 166 at its closest point and the position of the measuring plate 154 at moment when the measuring plate 154 reaches the lower end of the work w. The total length of the working bones w obtained in the manner described above is sent to a lifting stroke adjustment unit 178.
    [00100] The lifting stroke adjustment unit 178 determines which class of large, medium and small the detection value belongs to. The lifting stroke adjustment unit 178 adjusts the lifting stroke according to the given class. At the ninth work station (final meat separation station), the fixation unit is lifted by the amount of lift to separate the bones and the meat part m.
    Petition 870180033021, of 04/24/2018, p. 32/43
    26/28 [00101] As shown in FIG. 1 and FIG. 3, the cam plates 180 and 182 are arranged at the third workstation and between the ninth workstation and the tenth workstation respectively. At the second workstation, the incision is made while lifting work w. Then, when the clamping unit 12 starts in the direction of the third workstation, the roller 102 is on the bottom surface of the guide rail 110, thus moving the brake shoe 96a away from the axis of rotation 76. Therefore, the clamping unit 12 is released to fall, the lifting and lowering roller 92 moves in the travel path 94 while lowering the clamping unit 12.
    [00102] As FIG. 1 shows, the oscillating roller 84 is pressed by the cam plate 180 in order to rotate the axis of rotation 76 by the adjustment angle while the clamping unit 12 is transferred in the third work station. For this reason, the part of the tendon to be cut close to the ankle is positioned to face the pair of rounded cutting blades 22. The rounded cutting blades 22 move linearly towards the part of the tendon to be cut in order to cut the tendon attached to the ankle f. Then the clamping unit 12 is transferred and the swing roller 84 moves away from the cam plate 180. Since the swing roller 84 is outside the cam plate 180, the spring force of the spiral spring 80 rotates fixing unit 12 in the reverse direction to its original position.
    [00103] In a similar manner as above, the oscillating roller 84 is pushed by the cam plate 182 in order to rotate the clamping unit 12 90 degrees while the clamping unit 12 is transferred from the ninth work station to the tenth work station . For this reason, the part to be cut is positioned to face the rounded cutter blade 64. The rounded cutter blade 64 is moved towards the part to be cut in order to cut the tendon attached to the head end of the bone. femur j.
    [00104] According to the preferred embodiment, the lifting unit of the fixing unit 12 includes the servomotor 104, the threaded shaft 106 coupled to the output shaft of the servomotor 104 and the lifting and lowering block 108 which is threadedly mounted on the shaft threaded 106. The fixing unit 12 is
    Petition 870180033021, of 04/24/2018, p. 33/43
    27/28 lowered by moving the lifting and lowering roller 92 on the displacement path 94 arranged between the workstations. Thus, the lifting and lowering mechanism and the work transfer mechanism w are simplified and the energy required from servomotor 104 is reduced, thus achieving lowering of the cost. Using servomotor 104 as the drive motor, the working height w is precisely controlled.
    [00105] The clamping unit 12 is rotated by the adjustment angle so that the position of the part to be cut faces the rounded cutting blades 22 or the rounded cutting blade 64. The travel path of the rounded cutting blades can be approximately linear. Thus, the travel path of the rounded cutting blade can be simplified, thereby simplifying the mechanism for moving it and lowering the cost.
    [00106] The bone leg is moved up or down instead of displacing the unit to make a heavy incision with the incision knife in the vertical direction. Thus, there is no need for a lifting and lowering unit specifically for the heavy incision unit. This can simplify the incision station and lower the cost. In contrast to the deboning device of Patent Document 1 having the incision station and the deboning body separately installed, the incision station is integrated with the deboning device 10. Thus, the overall size of the deboning device can be smaller.
    [00107] When the incision knife 168 reaches the knee joint h, the fixation unit is rotated by the adjustment angle to move the incision knife 168 around a tendon connection of the knee joint ha from the curved surface internal bone. Thus, the tendon firmly attached to the knee joint h can be separated. As a result, the separation of the bone part and meat part can be carried out smoothly and the meat's yield rate is improved.
    [00108] At the second workstation (the incision station), the total length of work w is detected. It is determined which class of large, medium and small the detected value belongs to and the amount of withdrawal from the
    Petition 870180033021, of 04/24/2018, p. 34/43
    28/28 clamping unit 12 in the ninth workstation (final separation station) is adjusted. Thus, individual differences in work length do not affect as long as the meat part and bone part are firmly separated. The length of work w is categorized into three classes, which are large, medium and small, so that the control of them is simplified and the cost of the control unit can be reduced.
    [00109] The rotating mechanism 171 constituting only mechanical devices such as the oscillating roller 84, the spiral spring 80 and the cam 170, a complicated electronic control unit can be eliminated, the clamping unit 12 can be rotated with high precision and the cost of it can be reduced. By providing the input unit 14, the structure of the boning device 10 at the input station can be simplified and the work w can be firmly maintained on the fixing unit 12.
    [00110] By pressing the brake shoe 96a against the axis of rotation 76 while the clamping unit 12 is raised by means of servomotor 104 at each workstation, the axis of rotation 76 is prevented from falling. Releasing the brake shoe 96a by means of the guide rail 110 while the clamping unit 12 is moved between the workstations, the lifting and lowering roller 92 can move in the travel path 94 smoothly and the clamping unit 12 can be moved. gently lowered.
    Industrial Applicability [00111] According to the present invention, in the automated boning device for boning the leg with bone from the livestock carcass, the mechanism for displacing the cutting blades in the cutting process can be simplified and cheapened as well as simplifying the cutting mechanism. displacement of the cutting blades and reduce the cost by reducing the energy required.
