FIGS. 1A to 1D are perspective views showing a full-length measuring device 10 for bone-filled meat according to an embodiment in time series. The jig 12 is configured to hold the flesh Mb and move horizontally (in the direction of arrow a). The bone-flesh Mb is transported by the jig 12 along a fixed transport path. A contact 14 is provided in the conveying path 22 of the bone-flesh Mb, and the pressing part 16 presses the contact 14 against the bone-flesh Mb being conveyed. The position sensor 18 detects the upper and lower positions of the contact 14, and the detection value of the position sensor 18 is input to the arithmetic unit 20 in the control unit 24. The control portion 24 controls the position of the contact 14 by controlling the operation of the pressing portion 16.

2 and 3 show the moving coordinates observed from the observer moving with the jig 12. That is, the vertical axis (first coordinate axis) is a static coordinate axis representing the detection value of the upper and lower positions of the position sensor 18, and the horizontal axis (second coordinate axis) is represented when the observer moves together with the bone-bearing Mb. The contact coordinate 14 moves to the upper and lower positions of the contact member 14. The calculation unit 20 obtains the distance from the reference position to the end detection position of the downstream end of the conveying direction of the boned meat Mb detected by the position sensor 18 as the total length of the boned meat Mb. The reference position is calculated based on the end detection position obtained for a plurality of bone-bearing Mb whose total length is known.

According to the above configuration, in the moving coordinate system shown in FIG. 2 and FIG. 3, the computing unit 20 obtains the downstream end of the transport direction of the bone-bearing Mb detected from the position sensor 18 (in FIG. 2) The distance of point D) is the full length of bone-bearing Mb. In this way, in the mobile coordinate system, only the distance from the known reference position to the downstream end of the detected bone-in meat Mb can be obtained, and the total length of the bone-in meat Mb can be easily obtained. In addition, it is possible to measure the full length without stopping the transported flesh Mb, thereby improving the measurement efficiency.

As shown in FIG. 2, when the contact 14 reaches the downstream end of the bone-carrying Mb in the conveying direction, the position of the contact 14 drops sharply, so the position sensor 18 can easily detect the downstream end position of the bone-carrying Mb in the conveying direction . In one embodiment, point S in FIG. 2 is a reference position set when the concave portion 12a of the jig 12 into which the flesh Mb is inserted passes directly below the front end of the contact 14 on the conveying path. In one embodiment, a threshold value may be set for the upper and lower positions of the contact 14 based on the empirical value, and the time when the threshold value is reached is determined as the downstream end position in the conveying direction of the flesh Mb.

In one embodiment, as shown in FIG. 1A, the conveying path 22 is formed by a conveying path extending in the horizontal direction. The flesh Mb is transported on this transport path. For example, the transport path has a U-shaped cross section, the bone-bearing meat Mb is inserted into the transport path, and the jig 12 is transported along the transport path. In one embodiment, the transport path forms a linear transport path extending in the horizontal direction.

Fig. 1A shows the state of point A in Fig. 2, Fig. 1B shows the state of point B in Fig. 2, Fig. 1C shows the state of point C in Fig. 2, and Fig. 1D shows the state of point D in Fig. 2 status.

In one embodiment, the position sensor 18 is composed of an encoder. In one embodiment, a distance sensor (for example, an encoder) 26 that measures the transport distance of the jig 12 from the transport starting point is provided. In one embodiment, a plurality of jigs 12 are attached to the chain 28 at specific intervals, and the chain 28 is wound around the drive sprocket 30 at the end in the moving direction. The drive sprocket 30 is rotated by the motor 32, and the distance sensor 26 measures the rotation speed of the drive sprocket 30 to measure the transport distance of each jig 12 from the transport starting point.

Fig. 4 shows an example of bone-in chicken drumsticks as bone-in meat Mb. In FIG. 4, the inner leg surface Sin with a small area of the epidermis w faces upward. A bone portion b is connected from the ankle portion f, and a meat portion m is surrounded around the bone portion b. A knee joint part N exists inside the knee part n. Points B, C, and D in FIG. 4 correspond to points B, C, and D in FIG. 2.

In one embodiment, the bone-in meat Mb is bone-in chicken leg meat for edible poultry. As shown in FIG. 1, the bone portion b is arranged horizontally with the inner leg surface and outer leg surface in the vertical direction. The ankle portion f is held by the jig 12 on the conveying path 22. Since the contact 14 traces the contour of the undulating bone-in chicken leg meat between the inner leg surface and the outer leg surface, it is easy to detect the end of the position sensor 18. For example, it is possible to trace the outline of the undulating bone-in chicken leg including the knee n.

In one embodiment, the jig 12 has a recess 12a that opens upward and allows the flesh Mb to play. Since the bone-bearing meat Mb is fitted into the concave portion 12a instead of being firmly held, the concave portion 12a can be rotated in the vertical direction as a starting point. Therefore, the bone-bearing meat Mb can be transported while being in contact with the bottom surface of the transport path constituting the transport path 22. Since the concave portion 12a opens upward, even if the flesh Mb is fitted into the concave portion 12a, it will not fall out of the concave portion 12a.

In one embodiment, as shown in FIG. 1, the contact 14 includes a contact rod 14 a extending horizontally in a direction orthogonal to the conveying direction of the bone-flesh Mb at the front end portion. With the provision of the contact bar 14a, the contact member 14 can be prevented from falling off from the surface with the flesh Mb. The contact rod 14a can stably contact the surface of the bone-bearing Mb while sliding along the surface of the bone-bearing Mb.

In one embodiment, as shown in FIG. 1C, a cut-in blade 34 for cutting in the bone-bearing meat Mb is provided. The control section 24 causes the contact 14 to operate as a pressing member with bone Mb when the cutting line 34 is cut into the cutting line. According to this embodiment, since the cutting edge 34 is provided, the cutting edge of the bone Mb can be cut together with the measurement of the full length of the bone Mb. Moreover, since the contact 14 can be used as a pressing member for the flesh-bearing Mb at the time of cutting in the cut line, the flicking of the flesh-bearing Mb at the time of cutting in the cut line can be suppressed. With this, the cut lines can be correctly drawn. In one embodiment, as shown in FIG. 1C, the cutting edge 34 is configured to enter the position below the front end of the contact 14. Thereby, the contact 14 can be effectively used as a pressing member for bone-bearing Mb when the cut line is scratched.

In one embodiment, in the moving coordinates shown in FIG. 2, the control unit 24 uses the contact 14 to detect the position (point C) of the joint of the knee joint portion N of the bone Mb detected by the position sensor 18. The position of the upstream side actuates the contact 14 so as to contact the flesh Mb. According to this embodiment, since the knee joint portion N having a complicated shape can be supported by the contact 14 when the cut is drawn, the knee joint N can be cut accurately.

In one embodiment, in the moving coordinates shown in FIG. 2, the reference position S is the position of the jig 12 when the jig 12 reaches directly below the contact 14 on the transport path 22. The control section 24 actuates the pressing section 16 with the jig 12 reaching the reference position S as a starting point, and causes the contact 14 to contact the bone-bone Mb. According to this embodiment, the contact 14 can be brought into good contact with the boned meat Mb at a position downstream of the jig 12 in the conveyance direction and upstream of the boned meat Mb in the conveyance direction. Therefore, the contact 14 does not collide with the jig 12 and can move without contact with the bone Mb from the vicinity of the jig 12 without delay.

In one embodiment, the pressing portion 16 shown in FIG. 1A is composed of an air cylinder. Thereby, since the contact 14 can be elastically pressed against the surface of the bone-bone Mb, the bone-bone Mb will not be damaged, and the contact 14 will not be separated from the bone-bone Mb, so that the contact 14 can follow the bone-bone Mb surface. In one embodiment, the pressing portion 16 may have a spring member (not shown), and the contact member 14 may be elastically pressed against the surface of the bone Mb by the spring member.

In one embodiment, in FIG. 2 and FIG. 3, the selection from the time point when the contact 14 contacts the bone-bearing Mb (point B in FIG. 2) to the end detection position (point D in FIG. 2) When the detection value of the position sensor 18 at the position exceeds the threshold value, the calculation unit 20 determines that the bone Mb is not held by the jig 12. According to this embodiment, the situation where the bone-bearing meat Mb is not held by the jig 12 can be detected based on the detection value of the position sensor 18. This can prevent erroneous detection of the full-length measuring device 10.

In one embodiment, a display unit is provided, which displays the trajectory of the contact 14 from the reference position S to the end detection position D at least on the two-dimensional moving coordinates shown in FIGS. 2 and 3. According to this embodiment, by displaying the position of the contact 14 on a two-dimensional coordinate, the trajectory of the contact 14 can be visually displayed, and the full length of the bone Mb can be visually displayed. In addition, in the two-dimensional coordinates shown in FIGS. 2 and 3, the vertical axis represents the amount of descent of the contact 14. The greater the amount of descent of the contact 14, the higher the contact 14 is on the vertical axis.

FIG. 2 shows the upper and lower positions of the contact 14 when the bone-bearing Mb is held on the jig 12, and FIG. 3 shows the upper and lower positions of the contact 14 when the bone-bearing Mb is not fixed on the jig 12. In FIG. 2, the distance L ₀ from the set position A ₀ to the reference position S from the start of measurement is known, and the total length L of the flesh Mb can be obtained by subtracting the distance L ₀ from the distance between the points A and D.

In FIGS. 2 and 3, Pz represents a position selected after pressing the contact 14 against the bone-bearing meat Mb to the setting position at the end of the measurement. For example, in FIG. 2, the point B to the point D becomes the selection position. As shown in FIG. 2, when the detection value H of the position sensor 18 at the selected position Pz is the threshold value Hth ₁ ≦H≦threshold value Hth ₂ , it is determined that the jig 12 holds the flesh Mb. As shown in FIG. 3, when the detection value H of the position sensor 18 in the time period Tz is H<Hth ₁ or Hth ₂ <H, it is determined that the jig 12 does not hold the bone-bearing meat Mb. The thresholds Hth ₁ and Hth ₂ are set in advance based on the size and shape of the bone-bearing Mb. In this manner, according to FIGS. 2 and 3, it can be clearly grasped whether the jig 12 holds the bone-bone Mb.

In one embodiment, the full-length measuring device 10 is provided in a processing device (not shown) that disassembles the bone-bearing meat Mb to separate the bone from the meat. For example, the full-length measuring device 10 is provided in a cut-and-strip device that cuts and cuts the bone-bearing meat Mb. In the slitting device, a cut is formed between the bone b of the bone-bearing meat Mb and the meat m, and then the bone-bearing meat Mb is separated into the bone b and the meat m. By disposing the full-length measuring device 10 in the above-mentioned processing device, the disintegration process can be performed without stopping while transporting the bone-bearing meat Mb, so that the time required for the disassembly process can be shortened. In addition, the disassembly process can be performed based on individual differences in the full length of the bone-bearing meat Mb determined by the full-length measuring device 10, and the separation of the bone portion b and the meat portion m can be performed reliably and with good yield.

As shown in FIG. 5, the method for measuring the full length of the bone-bearing meat Mb in one embodiment first transports the bone-bearing meat Mb in the horizontal direction (transport step S10). Next, the contact 14 is pressed against the bone-bone Mb conveyed in the conveying step S10, and the upper and lower positions of the contact 14 are detected (detection step S12). Next, based on the detected upper and lower positions of the contact 14, it is determined whether the contact 14 reaches the downstream end position (point D in FIG. 2) of the bone-carrying Mb in the conveying direction (decision step S14 ). Next, from the moving coordinates shown in FIGS. 2 and 3, the position from the reference position (for example, point S in FIG. 2) to the downstream end position in the transport direction of the bone-bearing Mb detected by the position sensor 18 is obtained The distance is the full length of the bone-bearing Mb (calculation step S16).

According to this embodiment, in the calculation step S16, the distance from the known reference position to the terminal detection position can be easily obtained as the total length of the bone-bone Mb. In addition, it is possible to measure the full length while conveying the flesh-bone Mb without stopping, thereby improving the measurement efficiency.

In one embodiment, the distance from the reference position to the downstream end position in the conveying direction may be based on the time difference between the time when the contact 14 reaches the downstream end position in the conveying direction of the bone-bearing Mb from the reference position, and the conveying speed of the bone-bearing Mb Find the product. With this, the full length of the bone-flesh Mb can be measured without stopping, and the measurement time can be shortened and the measurement efficiency can be improved.

In one embodiment, in the conveying step S10, the bone-bearing meat Mb is transported, while a cut line is inserted into the lower part of the bone b of the conveyed bone-bearing Mb, and the blade 34 is inserted into the bone b and meat m of the bone-bearing Mb. Cuts are formed between them (cutting lines are drawn into step S18). In the cut-out step S18, the contact 14 is brought into contact with the bone-bone Mb and supports the bone-bone Mb. According to this embodiment, since the contact 14 can be used as a pressing member for flesh and bone Mb when cutting in a cut, the flicking of the flesh and bone Mb during cutting in can be suppressed. With this, the cut lines can be correctly drawn.

In one embodiment, in the conveying step S10, the bone-bearing meat Mb is held by the jig 12, and the bone-bearing meat Mb is conveyed along the horizontal direction with the bone portion b of the bone-bearing meat Mb. According to this embodiment, since the bone portion b of the bone-bearing meat Mb is transported in the horizontal direction, the full-length measurement of the contact 14 can be performed without stopping the bone-bearing meat Mb while being transported.

In one embodiment, the distance L ₀ , which is a fixed value, is obtained by multiplying the product of the time difference between points A and D shown in FIG. 2 and the transport speed of bone-bearing meat Mb, and L is obtained as the actual bone-bearing meat Mb. full length.

In one embodiment, as shown in FIG. 4, the bone-in meat Mb is bone-in chicken leg meat for consuming poultry carcasses, etc. The bone-in chicken leg meat is horizontally along the horizontal direction with the bone portion b and the inner leg surface and outer leg The ankle portion f is held by the jig 12 in a posture in which the surface is in the up-down direction. Since the contact 14 traces the contours of the bone-bone chicken drumsticks between the inner leg surface and the outer leg surface, it is easy to detect the end of the bone-bearing Mb by the position sensor 18. In addition, bone-bearing meat Mb may also be bone-bearing leg meat (including forelimbs and hindlimbs of edible poultry carcasses and livestock carcasses). Boneless chicken thighs are included in boneless thighs. [Industry availability]

According to one embodiment, the full length of the bone-in meat can be easily measured, and the bone-in meat can be measured while moving without stopping the movement of the bone-in meat. Therefore, when applied to the disassembly process steps of bone-bearing meat and the like, the disassembly process time can be shortened and the disassembly process efficiency can be improved.
