Method and device for rib deboning of rose

Technical field

[0001] The present invention automates the deboning work of the ribs of the rib parts obtained by dividing the carcass half-cut from the meat carcass for meat, and greatly improves the work efficiency compared to the manual work. The present invention relates to a deboning method and a device therefor that do not reduce the yield of meat attached to the ribs compared to the work.

Background art

FIG. 14 shows a divided part of a pig carcass as an example. When processing meat carcasses of livestock such as pigs, cattle, sheep, etc., firstly carcass half-cut from carcass carcass is divided into large parts 04, 05, loin rose parts 02, 03 and peach part 01 After that, deboning work is performed at each site. In the deboning work of the loose parts 02, 03, there are roughly two types of bones, the spine and the ribs. When these two types of bone deboning methods are performed manually, the ribs are first cut into the ribs, and the ribs and meat are peeled off by pulling on the strings. After that, the joint strength of the ribs is also folded and separated from the spine to complete the debonation of the ribs and then the spine.

[0003] Unlike the removal of the ribs, the spine is removed by cutting with a knife all the work to remove the bone and meat. The spine has irregularities such as papillary processes and spinous processes, and has a very complex shape. Also, bone and meat are connected by strong muscles and cannot be peeled off, and in order to perform bone removal with a high yield, an operator must perform a very complicated knife movement manually to separate bone and meat. I must. In this way, the spine and meat are separated and the deboning is completed.

[0004] Conventionally, as a method of deboning the ribs of the loin ribs, for example, Patent Document 1 (Japanese Patent Laid-Open No. 10-179015) discloses an incision groove in the upper part of the rib base of the loin rib ribs and rib joints. A string-like member is placed in the incision groove, and the string-like member hangs from the upper side of each rib to the lower part of the rib, and the gap between the ribs is hidden, and the string-like member is suspended in the bone part. Pull the bone removal loop group formed at the same time to the lower part of the ribs at the same time, An enabled method is disclosed.

[0005] However, the method disclosed in Patent Document 1 is a method that can improve the work efficiency in that the deboning process of all the ribs can be performed in a lump. However, the method is transverse to the base of the rib group. It is necessary to insert a hook from between the ribs into the string-like member placed in the incision groove provided in the hook and hook the string upper member with the hook provided at the tip of the hook. The operation of the hook requires some degree of precise control.

In addition, there is a process that requires manual work such as fixing the loose parts to the fixing plate, and it has not been fully automated, so there is still room for improving work efficiency.

[0006] In addition, the present inventors previously proposed a method for deboning the ribs of the loose ribs by making a U-shaped cut around the end surface of the rib with a pipe-shaped cutter and inserting a U-shaped string into the cut. However, it is a method of separating the meat up to the joint with the spine by pulling the string as it is along the rib surface (Patent Document 1; Japanese Patent Application Nos. 2005-49801 and 2; Patent Application 2005). — 49802).

Problems to be solved by the invention

[0008] In the methods and devices of Patent Documents 2 and 3, the deboning operation of the ribs is almost completely automated, and the working efficiency is greatly improved as compared with the manual operation, and a flexible string is used. Therefore, it is possible to separate the meat by bringing the string into close contact with the rib surface, and this has the advantage of not reducing the yield, but it requires two stages of cutting (stitching) and stringing (meat separation) processes. However, there is room for improvement in that it cannot be deboned in one step and the device configuration is complicated.

[0009] The loose portion is further separated into loin 02 and rose 03 as shown in FIG. 14. Loose 02 is used as roast or ribbed meat (spare rib), and rose 03 is spare rib or other. It is used for the cooking method. [0010] In view of the problems of the prior art, the present invention simplifies the deboning work of the ribs of the rose portion separated from the loin and is fully automated so that it can be performed in a series of operations. It is an object of the present invention to provide a rib deboning method and apparatus for ribs that improves work efficiency and does not reduce the yield of meat remaining in the ribs compared to manual work. Means for solving the problem

[0011] In order to achieve this object, the rib deboning method of the rose portion of the present invention,

In a method of deboning the ribs of the rose after carcass carcasses half cut into large pieces,

A cutter main body is integrally provided with an arcuate cutting edge whose lower cross section is along the rib surface and a roller that presses the rib surface upstream in the movement direction of the cutting edge,

A step of measuring a rib position of a rose portion placed on the work surface with the rib side facing upward; a step of moving the cutter body to the rib to be deboned;

Insert the blade edge around the distal end surface of the rib, and press the upper surface of the rib with the roller while contacting a cylindrical stubber whose outer diameter is smaller than the inner diameter of the blade edge on the distal end surface of the rib downstream in the meat separation direction And moving the cutter body in the longitudinal direction of the rib in a state where the lower surface of the rib is pressed against the cutting edge until the cutting edge comes outside the peripheral surface of the stagger, and separating the meat around the rib. It is characterized by comprising.

[0012] In the method of the present invention, first, the rose part is placed on the work surface with the rib side facing upward. Then, after measuring the rib position, the rib is removed.

The rib position measurement method includes, for example, a thin plate-like detection plate having a detection unit protruding at a position in contact with a loose part and a sensor sensing unit protruding in a direction different from the detection unit, and a plurality of the detection plates A detection unit is prepared that includes a support shaft that is swingably supported in a state where the detection plates are stacked, and a proximity sensor group that is provided at a position facing each sensor sensing portion of the plurality of detection plates. Then, the detection unit is moved so that the detection unit comes into contact with a portion to be inspected of a loose part placed on the work surface with the rib side facing upward, and the proximity sensor is turned on / off by the shaking of the sensor sensing unit. The rib position is detected by looking at the state.

[0013] As another measuring method, the detection roller is imitated on the surface of the rib in the spine direction with respect to the rib group. The copying position of the detection roller that is moved up and down according to the unevenness of the ribs

The blade tip position of the cutter body is determined by reading it into the PU and performing the required calculations. In both of the above methods, if two detection units or detection rollers are provided and run along the both ends of the rib, the length of the rib and the inclination with respect to the reference plane can be calculated simultaneously from the positional information of the both ends of the rib. Can be obtained quickly and accurately.

[0014] After measuring the rib position by such a measurement method, the cutter body is moved to the rib position to be deboned so that the moving direction of the blade edge matches the inclination of the rib measured in the measurement step. Rotate the cutter body. Then, the cutter main body is placed so that the roller attached to the cutter main body is positioned on the longitudinal axis of the rib on the surface of the rib at the rib position.

At this time, the roller and the blade edge attached to the cutter body are in close contact with the surface of the rose portion, making it easy to insert the blade edge around the rib tip surface and ensuring the contact of the roller with the rose surface. Therefore, the cutter body is placed with a pressing force applied to the surface of the rose part.

[0015] Next, the cutting edge is inserted around the distal end surface of the rib, and a cylindrical stagger whose outer diameter is smaller than the inner diameter of the cutting edge is brought into contact with the distal end surface of the rib on the downstream side in the meat separation direction to move the rib in the longitudinal direction. The cutter main body is moved in the longitudinal direction of the rib in a state where the upper surface of the rib is pressed with a roller and the lower surface of the rib is pressed against the blade edge. At this time, the blade edge is moved until it comes to the outside of the circumferential surface of the cylindrical stagger, and the meat around the rib is separated.

That is, when the upper surface of the rib is pressed with a roller, the cutting edge comes into close contact with the lower surface of the rib. For this reason, if the cutter body is moved in the longitudinal direction of the rib while the upper surface of the rib is pressed by the roller, the meat is separated while the cutting edge is in close contact with the rib surface, so that the meat remaining on the rib surface is reduced. Can do.

[0017] Further, since the outer diameter of the cylindrical stagger is configured to be smaller than the inner diameter of the cutting edge, the cutting edge that moves while separating the meat toward the distal end face side of the rib in the meat separation direction is opposed to the distal end face of the rib. Since it can move smoothly outside the outer periphery of the stagger without hitting the contacting stagger, the rib tip surface force can be separated without any trouble over the entire length of the rib to the end surface.

[0018] In addition, bulk parts are placed on a conveyor and arranged at equal intervals along the conveyor. In order to stop the loose parts at multiple deboning stations with different inner diameters at the lower part of the cutting edge, the ribs are grouped according to their outer diameters, and each group has a cutting edge adapted to the outer diameter. If the deboning process is performed at the deboning station having an inner diameter, the meat remaining in the ribs can be further reduced.

Next, the deboning device of the present invention for carrying out the method of the present invention comprises:

In a device for removing the ribs in the ribs after the carcass half cut into carcasses has been divided into large parts,

A cutter body integrally provided with an arcuate cutting edge whose lower cross section is along the rib surface and a roller for pressing the rib surface on the upstream side in the movement direction of the cutting edge;

It is provided integrally with the cutter body, and when the rib is deboned, it faces a distal end surface of the rib on the downstream side in the meat separation direction and has a cylindrical stagger that has an outer diameter smaller than the inner diameter of the cutting edge,

The cutter body is moved in the longitudinal direction of the rib while pressing the upper surface of the rib with the roller in a state where the blade edge is inserted into one rib end face.

In the device of the present invention, first, the position of the rib to be deboned is measured by the rib position measuring means. Next, the cutter main body is moved to the position of the measured rib, and the cutter main body is rotated so that the moving direction of the blade edge matches the inclination of the rib measured in the measurement step. In this way, the cutter body is placed on the surface of the rose portion so that the roller is positioned on the longitudinal axis of the rib and the cylindrical stubber faces the end face of the rib.

When a means for applying a pressing force to the loose part is provided when the cutter body is placed on the loose part, the roller is likely to be in close contact with the surface of the loose part, and the cutting edge is likely to be cut around the distal end surface of the rib. .

In the device of the present invention, the cutter body is configured to move in the longitudinal direction of the rib while pressing the upper surface of the rib with a roller in a state where the blade edge is inserted into one rib end surface! The meat on the rib surface in a state where the blade edge is in close contact with the lower surface of the rib by the pressing force of the roller. Separation can be performed.

If the cutter body is supported so as to be able to swing from the horizontal direction to the tilt direction, the cutter body can follow the surface of the ribs and the ribs, and the meat can be separated smoothly. At the same time, the meat remaining on the ribs can be minimized.

[0022] Further, in the apparatus of the present invention, a conveyor for placing and transferring the bulk parts, a plurality of deboning stations arranged at equal intervals along the conveyor and having different inner diameters of the lower edge of the blade, Means for measuring the positions of both ends of each rib of the rose placed on the conveyor, and the position force at both ends of each rib. The length of each rib is detected, and each rib is calculated from the length of each rib. A decision circuit for determining the outer diameter of the bone, and tact-feeding the bulk portion so as to stop at the deboning station, and having a cutting edge adapted to the outer diameter of the rib determined by the determination circuit If it is configured to be deboned at the station, it can be deboned with a cutting edge with an inner diameter that matches the outer diameter of each rib in the rib group, so that less meat remains on the rib surface. be able to.

A step of measuring a rib position of a rose placed on the surface with the rib side facing upward; a step of moving the cutter body to the rib to be deboned; and inserting the blade edge around the distal end surface of the rib Then, while the cylindrical end of the rib is smaller than the inner diameter of the cutting edge against the end face of the rib on the downstream side in the meat separation direction, press the upper surface of the rib with a roller and press the lower surface of the rib against the cutting edge. The cutter body is moved in the longitudinal direction of the rib until the cutting edge comes outside the outer surface of the stagger, and the meat around the rib is separated, so that the deboning process of the rib can be fully automated, Can greatly improve processing efficiency. Quilts and monitor, a deboning process of ribs can be carried out in one step, to enable the simplification of the deboning process. In addition, the amount of meat remaining on the rib surface does not increase compared to manual work, and the meat yield is not reduced.

At each station, the rib deboning device 60 and the rib position detecting device 30 slide on the ball screw 33 in the direction indicated by the arrow j while being integrally fixed to a common support 51. Station S1 is equipped with a cutting edge 83 that has a large outer diameter and fits the radius, station S2 is equipped with a cutting edge that fits a medium class outer diameter rib, and station S3 has a small outer radius. It is equipped with a cutting edge that fits.

[0044] Since the outer radius of the rib group is usually larger on the head side and directed toward the caudal side, the outer diameter becomes smaller. In station S1, the rib group on the head side becomes the target of deboning, and in station S2, the intermediate portion In the station S3, the rib group on the caudal side is the target for deboning.

The loose part 03 starting from the loading position T is first stopped at the station S1, where the rib position detecting device 30 first detects the rib position, and then the rib deboning device 60 debones the rib group having a large outer diameter. .

[0045] Next, the loose portion 03 is tact-fed to the station S2, and the deboning process of the rib having a medium outer diameter is performed at the station S2. After that, it is further fed to station S3 where the outer diameter is small and the ribs in the area are deboned.

Next, a rib position detection method using the rib position detection device 30 will be described. In FIG. 8, the rib portion 03 has 11 to 13 rib groups 07 which are buried on the thin plate-like rose meat 09 other than the surface in parallel. The overlapped detection plate 39 swings around the support shaft 40, and the sensor sensor 42 swings with respect to the fixed proximity sensor 43, so that the proximity sensor 43 fixed to the box 37 is turned on, It is a mechanism to switch off.

[0047] The weight 52 provided integrally with the detection plate 39 is used to keep the detection plate 39 in the same position. The sensor sensing unit 42 detects the proximity sensor 43 unless an external force is applied. The proximity sensor 43 is in the ON state at this time. FIG. 8˜: As in the example shown in L 1, the weight 52 having the above action may be integrally provided on the detection plate 39.

Adjacent detection plates have different sensor sensing portions 42 in order to prevent the proximity sensor 43 from interfering.

[0048] For detection of the rib position, the detection unit 38 is first brought close to the loose part 03 as shown in FIG. Since there is an individual difference in the thickness of the rose part 03, the detection unit 38 is lowered by the air cylinder 34 so that the height becomes an appropriate height. In that case, the loose part of the detection unit 38 03 The position of the detection unit 38 with respect to the bulk site 03 is set by applying a copying plate 48 fixed to the downstream side of the guide plate 36 to the surface of the bulk site 03 so that the height with respect to the guide plate 36 is constant. By using the copying plate 48 in this way, a uniform force is exerted on the loose portion 03, and the loose portion 03 can be crushed. In addition, the copying force is applied to the plate 48 by the aerodynamic force of the air cylinder 34. And the copying plate 48 can be adhered to the surface of the loose part.

Next, as shown in FIG. 10, the detection plate 39 is passed over the bulk site 03 so that the detection unit 41 projecting downward contacts the bulk site 03. When the detection unit 41 comes into contact with the hard rib 07, the detection plate 39 rotates around the support shaft 40 in the direction of the arrow k (clockwise), and the sensor detection unit 42 moves out of the detection range of the proximity sensor 43, and the proximity sensor 43 Is turned off.

[0050] On the other hand, as shown in FIG. 11, when the detection plate 39 passes over the loose meat 09, the weight 09 is crushed by the action of the weight 52, and the detection plate 39 does not rotate. Keep state.

By storing the position information of the proximity sensor 43 that has been turned off most quickly using the principle of force, it is possible to know the exact end face position of the rib 07 and the center position of the bone.

[0051] In the present embodiment, the two detection units 38a and 38b are respectively positioned at both ends of the rib and simultaneously operated to detect both ends of the rib 07. Therefore, the end face position and center of the rib 07 are detected. By calculating on the basis of the position information of both ends of the rib only by the position, the inclination of the rib and the length in the longitudinal direction can be calculated.

Next, a description will be given of a deboning process operation of the radius in the present embodiment. In FIG. 5, (a) shows the state before the deboning process of the rib deboning apparatus 60. (B) shows the state after the deboning process. At this time, the moving frame 66 is pushed in the direction of the arrow h by the air cylinder 65, and the cutter body 80 is also pushed out in the direction of the arrow h at the same time as the moving frame 66. A U-shaped cutting edge 83 is located outside the outer periphery of the cylindrical stopper 84 fixed to 64.

[0053] In FIG. 1, a long hole 73 is provided in the moving frame 66 to allow the cutter body 80 to tilt in the direction of arrow g. In the configuration of FIG. 5, as shown in FIG. By replacing the link 70 in FIG. 1 with a coil panel 75 instead of 73, the cutter body 80 is allowed to tilt in the direction of arrow g. In addition, it is equipped with both the long hole 73 and the coil panel 75 If the body 80 is allowed to tilt in the direction of arrow g, the tilt of the cutter body 80 in the direction of arrow g can be further facilitated.

FIG. 5 (d) shows the state at the start of deboning, (e) during the deboning, and (f) at the end of deboning.

At the start of deboning, the positions of both ends of the ribs are detected in the rib position detection step, and the inclination and length of the ribs 07 can be calculated accordingly. First, the rib deboning device 60 is centered on the rotation shaft 63. Rotate to align the movement direction of the cutter body 80 in the f direction with the inclination of the rib 07. Then, the air cylinders 62 and 65 are operated to move the cutting edge 83 to a position where it contacts the rib tip end face 07a as shown in FIG. 5 (d).

Then, the cutter body 80 is placed on the loose part 03, and the cutter body 80 applies a pressing force to the surface of the loose part below the arrow m by the aerodynamic force of the air cylinder 71.

[0055] Then, the air cylinder 65 is operated to move the cutter body 80 in the direction of the arrow h, and the cutting edge 83 is inserted between the rib distal end surface 07a and the surrounding meat 09 to cut both. FIG. 5 (e) shows the force during the deboning. At this time, the roller 81 presses the surface of the loose part with the elastic force of the coil panel 82, so that the cutting edge 83 comes into close contact with the surface of the rib. During the deboning process with the pressing force of the roller 81, the cutting edge 83 comes into close contact with the rib surface, so that the meat remaining on the rib surface can be minimized and the meat yield can be improved.

[0056] Further, during the deboning process, the cylindrical stubber 84 abuts against the rib end surface 07b to fix the rib, so that the deboning is not hindered. FIG. 5 (f) shows the end of deboning. At this time, the cutting edge 83 reaches the outer periphery of the cylindrical stagger 84, and the deboning of the rib can be completed in one step. Since the outer diameter of the cylindrical stopper 84 is smaller than the inner diameter of the cutting edge 83, the cutting edge 83 can be smoothly moved to the outer periphery of the cylindrical stopper 84.

[0057] In this example, as shown in Fig. 6, the three stages of stations S1 to S3 with different outer diameters of the cutting edges 83 were installed along the belt conveyor 21 and equipped with cutting edges with large outer diameters. Station S1 removes the ribs of the large outer diameter, and station S2 equipped with the middle class outer diameter of the ribs removes the ribs of the intermediate class outer diameter and equipped with the blade of the smaller outer diameter In S3, the small and outer radius ribs are deboned! /, So the meat remaining in the ribs can be further reduced and the meat yield can be further improved.

[0058] Thus, according to the present embodiment, in the rib position detecting step, the detection plate 3 on which the rib hits. Since the proximity sensor 43 can be identified by turning the proximity sensor 43 on and off, the rib position of the loose part can be detected with high accuracy and the detection accuracy is high, so that the movement of the detection unit 38 can be performed at high speed. It is possible to shorten the detection time.

Further, since both ends of the rib can be detected simultaneously by the two detection units 38a and 38b, it is possible to calculate the inclination and length of the rib, thereby efficiently performing the deboning process in the subsequent process.

[0059] Further, in the rib deboning process, the deboning of one rib can be completed with one movement of the cutter body 80, the processing process can be shortened, and the position of the rib can be detected. Since it can be fully automated until force deboning, work efficiency can be greatly improved. In addition, since the roller 81 applies a pressing force to the loose part 03 at the time of bone removal, the meat part can be separated while the cutting edge 83 is in close contact with the rib surface, thereby improving the meat yield. Monkey.

[0060] Further, the deboning process is divided into three stations S1 to S3, and each station uses a cutter body 80 with different cutting edge outer diameters. Therefore, the yield of meat remaining on the ribs can be further improved.

Example 2

Next, a modified example of the first embodiment will be described with reference to FIG. 12 as a second embodiment of the present invention. In the first embodiment, as shown in FIG. 6, the deboning process is divided into three stations S1 to S3, each of which is equipped with a cutter body 80 having a different blade outer diameter, and the outer diameter of the rib is large. It is divided into small and medium groups, and the deboning process is performed at three stations according to the outer diameter of the cutting edge. In this embodiment, the deboning process, which is effective by the control system 90 shown in the block diagram of FIG. 12, can be fully automated.

In FIG. 12, the position information of both ends of the ribs detected by the detection units 38a and 38b is sent to the calculation unit 91. The calculation unit 91 calculates the length of the ribs and the reference plate 22 from the position information of both ends of the ribs. The inclination of the rib is calculated. The memory 92 stores contrast information on the length and thickness of the ribs, and the rib length calculation value sent from the calculation unit 91 in the rib thickness determination unit 93 and the contrast information power sent from the memory 92 are also detected by the detection unit 38a. And rib thickness detected in 38b Determine.

[0063] This determination result force is also determined by the cutting command unit 94 at which station the deboning process is performed. The ribs are generally grouped into large, medium and small head forces, since the ribs on the head side generally become thinner toward the thicker caudal side.

According to the present embodiment, the deboning process grouped into the station S1 (large rib thickness), the station S2 (middle) and the station S3 (small) can be completely automated.

Next, as a third embodiment of the present invention, an example using another rib position detecting device will be described.

In FIG. 13, a rib position detecting device 100 includes a linear guide 103 that travels perpendicularly to the base or tip of the rib group 07, a detection base 101 that travels by connecting the linear guide 103 with a ball screw 106, and A detection roller 102 that detects the undulation state of the uneven surface formed by the rib group mounted on the gantry 101, and an encoder B108 that detects the elevation of the detection roller by a combination of a rack gear and a pion gear provided on the lifting shaft 107 And an encoder A105 provided in the ball screw drive motor 104 for detecting the travel position.

[0065] With the above configuration, when the detection roller 102 travels following the outer surface of the rib portion of the rose portion 03, the detection roller 102 rises at the rib position, and the roller 102 falls at the flesh portion between the ribs. If the pulse axis of encoder B105 indicating the running position is plotted on the horizontal axis and the number of pulses of encoder B108 indicating the undulation status of the rib surface is plotted on the vertical axis, and the status of the change is shown on the graph, Fig. 13 (c) And the position of rib 07 can be detected.

The read detection data is read by a CPU of a control unit (not shown), and a required calculation is performed to determine the position of the cutting edge 83 of the cutter body 80.

If two detection rollers 102 are provided and run along both ends of the ribs, the rib length and the inclination with respect to the reference plane are calculated simultaneously from the rib position information of the two rollers as in the first embodiment. And various position information of the ribs can be obtained quickly.

In addition to simplifying the processing process, it is possible to fully automate the process of detecting the rib position and the deboning process, thereby shortening the processing time and greatly improving the processing efficiency. In addition, the meat remaining in the ribs can be minimized, and the yield of meat is not reduced compared to manual work.
