However, those skilled in the art can clearly understand the composition and action and effect of the elements shown in each figure in consideration of the description of the present specification and the scope of claims.

The specific type of food in the following embodiments is not particularly limited. Therefore, the food may be livestock meat (beef, pork, etc.) cut into chunks, poultry meat (chicken, etc.), vegetables, and the like.

Drill First, the drill 10 according to the present embodiment will be described with reference to FIGS. 1 to 5. This drill 10 is used in the foreign matter removing device 50 described later for removing the foreign matter F (see FIG. 6) of the food H (see FIG. 6), and is for removing the foreign matter F from the food H.

As shown in FIGS. 1 to 3, the drill 10 extends from the tip portion 20 on which the blade 21 for removing the foreign matter F is formed and the rear end portion side (upper side of FIGS. 1 to 3) from the tip portion 20. It includes a main body portion 30. Of these, the tip portion 20 is formed in a conical shape. In this case, the height H1 of the tip portion 20 may be about 10 mm or more and 50 mm or less. Further, in the cone defined by the tip portion 20, the diameter of the bottom surface is the same as the diameter R1 of the main body portion 30, which will be described later.

The tip portion 20 is formed with a first opening 22 in which the outer edge 22a constitutes the blade 21. As shown in FIG. 4, when viewed from the tip 20a side of the drill 10, the distance from the central axis X1 of the drill 10 to the outer edge 22a changes along the circumferential direction of the outer edge 22a. As a result, when the drill 10 rotates about the central axis X1 of the drill 10, the foreign matter F can be removed while cutting the food H by the blade 21 formed by the outer edge 22a of the first opening 22. It has become. The first opening 22 is formed at a position that does not overlap the central axis X1 of the drill 10 when viewed from the vertical direction. That is, the first opening 22 is formed on the side surface of the cone defined by the tip portion 20. In the present embodiment, one first opening 22 is formed in the tip portion 20. The first opening 22 may be formed at a position overlapping the central axis X1 of the drill 10 when viewed from the vertical direction.

Further, as shown in FIGS. 1 to 4, the tip portion 20 is located closer to the tip 20a than the first opening 22, and when the foreign matter F is removed from the food H, the tip portion 20 comes into contact with the food H to cause the food H. The pressing portion 23 (the region shown by the satin finish in FIGS. 1 to 4) is included. The pressing portion 23 plays a role of suppressing the food H from moving with respect to the drill 10 when the drill 10 removes the foreign matter F from the food H by pressing the food H downward.

The main body 30 is formed in a columnar shape. In this case, the height H2 of the main body 30 may be about 30 mm or more and 300 mm or less. Further, the diameter R1 of the main body portion 30 may be about 10 mm or more and 50 mm or less.

The main body 30 is formed with a second opening 31 that communicates with the first opening 22. The second opening 31 is formed on the side surface 32 of the main body 30. The second opening 31 serves to discharge the foreign matter F removed by the blade 21 from the inside of the drill 10. In the present embodiment, one second opening 31 is formed in the main body 30. Further, in the present embodiment, the circumferential position of the second opening 31 is different from the circumferential position of the first opening 22. Specifically, the above-mentioned first opening 22 is formed on one side (left side in FIG. 3) with respect to the central axis X1 of the drill 10 in the side view, and the second opening 31 is formed in the side view. It is formed on the other side (right side in FIG. 3) with respect to the central axis X1 of the drill 10. In this case, the first opening 22 and the second opening 31 described above are formed so as to face each other with respect to the central axis X1 of the drill 10.

As shown in FIG. 3, the through hole 11 that communicates the first opening 22 and the second opening 31 extends so as to be inclined with respect to the central axis X1 of the drill 10. In this case, the inclination angle α of the central axis X2 of the through hole 11 with respect to the central axis X1 of the drill 10 can be about 20 ° or more and 50 ° or less. When the inclination angle α of the through hole 11 is 50 ° or less, the second opening 31 formed on the side surface 32 of the main body 30 can be kept away from the tip 20 of the drill 10. As a result, even when the drill 10 is inserted into the housing 80 described later so that the second opening 31 of the drill 10 is located in the chamber 81 described later in the foreign matter removing device 50 described later, the housing 80 The length of the tip portion 20 of the drill 10 protruding from the can be secured. Therefore, when the foreign matter F adhering to the food H is removed by using the foreign matter removing device 50 described later, the tip portion 20 of the drill 10 can be surely brought into contact with the food H.

As shown in FIG. 5, the through hole 11 has a circular shape in a cross section orthogonal to the central axis X2 of the through hole 11. In this case, the diameter R2 of the through hole 11 can be about 5 mm or more and 30 mm or less. When the diameter R2 of the through hole 11 is 5 mm or more, the through hole 11 is clogged with the foreign matter F removed by the blade 21 and the food piece removed together with the foreign matter F (hereinafter, also referred to as foreign matter F or the like). It is possible to prevent it from being stored. In the illustrated example, the through hole 11 has a substantially constant diameter as a whole, but is not limited to this. For example, the diameter R2 of the through hole 11 may change on the way from the first opening 22 side to the second opening 31 side. Further, the shape of the through hole 11 in the cross section orthogonal to the central axis X2 of the through hole 11 is arbitrary and may be a polygonal shape.

Further, a shank portion 40 attached to a drill chuck 61 described later is provided on the rear end side of the main body portion 30. In the illustrated example, the shank portion 40 is formed in a columnar shape, and the diameter of the shank portion 40 is the same as the diameter R1 of the main body portion 30. The shank portion 40 is a so-called straight shank, but the shank portion 40 may be a so-called taper shank.

As shown in FIG. 6, in the present embodiment, the foreign matter removing device 50 is attached to the robot arm 51 and is configured to remove the foreign matter F from the food H conveyed by the conveyor 52. The robot arm 51 is connected to a control device (not shown), and the foreign matter removing device 50 is moved in the horizontal direction and the vertical direction by a signal from the control device.

As shown in FIGS. 7 and 8, the foreign matter removing device 50 includes the above-mentioned drill 10 and a driving device 60 that rotates the drill 10 around the central axis X1 of the drill 10. The drill 10 is attached to the drive device 60 via a drill chuck (not shown).

The drive device 60 may be, for example, a motor. The drive device 60 is connected to a control device (not shown), and the drill 10 is rotated by a signal from the control device. In the present embodiment, the drive device 60 is configured so that the drill 10 can be rotated in both forward and reverse directions. The drive device 60 is attached to a support member 53, and the robot arm 51 described above is attached to the support member 53. The drive device 60 may be directly attached to the support member 53, or may be attached to the support member 53 via an attachment member (not shown).

Further, as shown in FIG. 8, the foreign matter removing device 50 partitions the holding mechanism 70 that presses the food H from above to downward when removing the foreign matter F from the food H, the chamber 81, and the drill 10 The housing 80 in which the insertion hole 82 to be inserted is formed, and the discharge device 90 for discharging the foreign matter F in the chamber 81 are further provided.

In the present embodiment, the pressing mechanism 70 has a quadrangular flat plate-shaped member 71 and a pole 73 attached to the upper surface of the plate-shaped member 71 and provided with an elastic body 72. Of these, the plate-shaped member 71 is formed with a large number of small holes 71a from the upper surface to the lower surface (see FIG. 7). As a result, it is possible to prevent the food H from sticking to the plate-shaped member 71 when the plate-shaped member 71 is separated from the food H after the plate-shaped member 71 presses the food H from the upper side to the lower side. it can. Further, an opening 71b into which the drill 10 is inserted is formed in the center of the plate-shaped member 71. The lower surface of such a plate-shaped member 71 is substantially parallel to the transport surface of the conveyor 52 on which the food H is transported. The lower surface of the plate-shaped member 71 may be formed in a concavo-convex shape without forming the small holes 71a in the plate-shaped member 71.

As shown in FIG. 8, the pole 73 includes a first flange portion 74 provided at the upper end and a second flange portion 75 provided below the first flange portion 74. In the present embodiment, the poles 73 are attached to the four corners of the upper surface of the plate-shaped member 71, respectively. Further, each pole 73 penetrates the above-mentioned support member 53, and each first flange portion 74 is located above the support member 53. Further, the portion of the pole 73 between the first flange portion 74 and the second flange portion 75 is formed in a columnar shape. Further, the portion of the pole 73 below the second flange portion 75 is formed in a columnar shape having a larger diameter than the portion between the first flange portion 74 and the second flange portion 75. Not limited to this, the pole 73 may have a substantially uniform diameter as a whole. Further, the pole 73 may have an arbitrary shape. Further, the number of poles 73 is arbitrary, and the poles 73 may be provided at any location.

The elastic body 72 provided on the pole 73 is arranged between the second flange portion 75 of the pole 73 and the support member 53. The elastic body 72 is configured to be elastically deformed by being pressed upward by the second flange portion 75 of the pole 73 when the plate-shaped member 71 of the pressing mechanism 70 presses the food H from above to below. There is. As a result, the pole 73 and the plate-shaped member 71 can move in the vertical direction, and when the plate-shaped member 71 presses the food H from above to below, the drill 10 is pressed by the plate-shaped member 71. Can be exposed from the underside of the. The elastic body 72 may be, for example, a coil spring.

Next, the housing 80 will be described. The housing 80 is attached to the support member 53 via the connecting member 55. As described above, the housing 80 is formed with an insertion hole 82 into which the drill 10 is inserted. The size of the insertion hole 82 is such that the drill 10 inserted into the insertion hole 82 can rotate about the central axis X1 of the drill 10. Although not shown, a mechanical seal may be attached to the insertion hole 82 in order to suppress the intrusion of air into the chamber 81.

Further, the housing 80 partitions the chamber 81 as described above. The chamber 81 serves to accommodate foreign matter F and the like removed by the drill 10. In this case, the second opening 31 of the drill 10 is located in the chamber 81 when the drill 10 is inserted into the insertion hole 82. As a result, the foreign matter F or the like removed by the blade 21 of the drill 10 is accommodated in the chamber 81 through the first opening 22 and the second opening 31 of the drill 10. Therefore, it is possible to prevent the foreign matter F or the like removed from the food H from scattering to the surroundings. Further, since the removed foreign matter F or the like is housed in the chamber 81, for example, when the food piece removed together with the foreign matter F is reused as feed for livestock or the like, the removed food piece is efficiently used. Can be collected.

A suction pipe 91 is connected to the housing 80, and a discharge device 90 is provided on the downstream side of the suction pipe 91. As a result, by driving the discharge device 90, the inside of the chamber 81 can be depressurized, and the foreign matter F or the like contained in the chamber 81 can be sucked and discharged. Therefore, foreign matter F and the like can be efficiently collected. The discharge device 90 may be, for example, a pump. A foreign matter F or the like may be discharged through the discharge pipe by connecting a discharge pipe (not shown) to the housing 80 and sending air from the discharge device 90 into the chamber 81.

Next, the operation according to the present embodiment will be described. Here, first, a foreign matter removing method using the foreign matter removing device 50 will be described.

Foreign matter removal method

First, the food H is placed on the conveyor 52. Next, the food H is imaged by an X-ray inspection device, a camera, or the like, and the position of the foreign matter F adhering to the food H is specified by image processing or the like. At this time, the position coordinates of the foreign matter F are transmitted to a control device (not shown). The food H is conveyed to the downstream side by the conveyor 52.

Next, the drill 10 is brought into contact with the food H. In this case, first, the robot arm 51 is driven by a signal from a control device (not shown), and the foreign matter removing device 50 is arranged at a desired position in the horizontal direction. Next, the robot arm 51 lowers the foreign matter removing device 50.

At this time, as shown in FIG. 9A, the plate-shaped member 71 of the pressing mechanism 70 comes into contact with the food H, and the plate-shaped member 71 of the pressing mechanism 70 presses the food H from above to below, so that the food H moves. Suppress. By suppressing the movement of the food H in this way, it is possible to prevent the actual position of the foreign matter F adhering to the food H from deviating from the position specified by image processing or the like. Therefore, it is possible to reliably remove the foreign matter F adhering to the food H, and it is possible to suppress the removal of the food piece from the food H more than necessary. Further, by pressing the food H from the upper side to the lower side by the plate-shaped member 71 of the pressing mechanism 70, tension can be applied to the surface of the food H, and the foreign matter F can be easily cut from the food H.

After that, when the foreign matter removing device 50 is further lowered by the robot arm 51, the drill 10 comes into contact with the food H as shown in FIG. 9B. At this time, first, the pressing portion 23 (see FIGS. 1 to 4) of the tip portion 20 comes into contact with the food H. As a result, the food H is pressed downward by the pressing portion 23. Therefore, when the foreign matter F is removed from the food H by rotating the drill 10 as described later, it is possible to prevent the food H from moving with respect to the drill 10. Therefore, it is possible to more reliably remove the foreign matter F adhering to the food H, and it is possible to more effectively suppress the removal of the food piece from the food H more than necessary. In this case, the tip portion 20 of the drill 10 may be buried in the food H.

Next, as shown in FIG. 9C, the foreign matter F is removed by rotating the drill 10 in contact with the food H. At this time, the drive device 60 is driven by a signal from a control device (not shown), and the drill 10 is rotated. Then, by rotating the drill 10, the blade 21 formed on the tip portion 20 of the drill 10 is rotated. Therefore, the blade 21 cuts the foreign matter F from the food H together with the surrounding food pieces. Further, since the foreign matter F is removed while rotating the blade 21, the foreign matter F is removed without crushing a part of the food H. Therefore, the damage to the food H can be reduced. That is, the foreign matter F is removed from the food H without the cut surface of the food H becoming shabby. Further, since the foreign matter F and the like can be removed without crushing a part of the food H, it is possible to prevent the food pieces removed together with the foreign matter F from being crushed. Therefore, the shape of the food piece removed together with the foreign matter F can be maintained in a desired shape. When the drill 10 is brought into contact with the food H (see FIG. 9B), the drill 10 may already be rotated.

When rotating the drill 10 in contact with the food H, the rotation speed of the drill 10 can be about 1000 rotations / minute. The time for rotating the drill 10 can be, for example, about 0.1 seconds or more and 0.2 seconds or less. When the time for rotating the drill 10 is 0.1 second or more, the foreign matter F can be effectively removed from the food H. Further, since the time for rotating the drill 10 is 0.2 seconds or less, the work time for removing the foreign matter F can be shortened.

Further, in this case, the drive device 60 may rotate the drill 10 in both forward and reverse directions. For example, the drive device 60 may rotate the drill 10 in one direction for about 0.1 seconds, and then rotate the drill 10 in the other direction for about 0.1 seconds. In this way, the drive device 60 rotates the drill 10 in both the forward and reverse directions, so that the food H can be more effectively suppressed from moving due to the rotation of the drill 10. Therefore, it is possible to reliably remove the foreign matter F imaged by a camera or the like, and it is possible to suppress the removal of food pieces from the food H more than necessary.

By the way, the foreign matter F and the food piece cut out from the food H by the blade 21 are opened from the first opening 22 side to the second opening in the through hole 11 by the foreign matter F or the like cut out from the food H by the subsequent rotation of the drill 10. It is pushed to the 31 side. Then, as described above, the second opening 31 is formed on the side surface 32 of the main body portion 30, and the through hole 11 of the drill 10 extends so as to be inclined with respect to the central axis X1 of the drill 10 ( (See FIG. 3). As a result, among the foreign matter F and the like in the through hole 11, the centrifugal force accompanying the rotation of the drill 10 acts on the foreign matter F and the like located on the second opening 31 side of the central axis X1 of the drill 10. As a result, the foreign matter F or the like is easily discharged from the through hole 11.

The second opening 31 of the drill 10 is located in the chamber 81. As a result, the foreign matter F or the like discharged from the through hole 11 of the drill 10 is housed in the chamber 81. Therefore, it is possible to prevent the foreign matter F or the like removed from the food H from scattering to the surroundings. Further, since the removed foreign matter F or the like is housed in the chamber 81, for example, when the food piece removed together with the foreign matter F is reused as feed for livestock or the like, the removed food piece is efficiently used. Can be collected. In addition, in FIG. 9C and FIG. 9D described later, only the foreign matter F among the foreign matter F and the like is shown, and the food piece removed together with the foreign matter F is omitted in order to clarify the drawing.

At this time, the discharge device 90 may be driven to reduce the pressure in the chamber 81. As a result, the removed foreign matter F or the like located in the through hole 11 of the drill 10 can be sucked out from the through hole 11. As a result, foreign matter F and the like can be easily discharged from the through hole 11.

Then, as shown in FIG. 9D, the foreign matter removing device 50 is raised. At this time, the robot arm 51 is driven by a signal from a control device (not shown) to raise the foreign matter removing device 50. Next, in order to remove other foreign matter F adhering to the food H conveyed to the downstream side (right side shown in FIG. 9D) by the conveyor 52, the robot arm 51 causes the foreign matter removing device 50 to be positioned at a desired position in the horizontal direction. Placed in. Next, the robot arm 51 lowers the foreign matter removing device 50. As described with reference to FIGS. 9A-9C, the foreign matter F is removed from the food H. As described above, when the foreign matter F is removed from the food H, the movement of the food H is suppressed by the pressing mechanism 70 and the pressing portion 23 of the drill 10. As a result, even when the other foreign matter F of the food H is removed, it is suppressed that the actual position of the other foreign matter F deviates from the position specified by image processing or the like. Therefore, other foreign substances F adhering to the food H can be reliably removed without taking an image of the food H again with a camera or the like. In addition, it is possible to prevent the food pieces from being removed more than necessary from the food H.

In this way, the food H from which the foreign matter F has been removed can be obtained.

On the other hand, the foreign matter F and the food piece removed from the food H and contained in the chamber 81 are discharged to the outside of the chamber 81 by the discharge device 90. At this time, by driving the discharge device 90, the inside of the chamber 81 is depressurized, and the foreign matter F or the like contained in the chamber 81 is discharged to the outside of the chamber 81 via the suction pipe 91. Therefore, the foreign matter F and the food piece removed together with the foreign matter F can be efficiently collected.

Manufacturing method of processed foods

Next, a method for producing processed foods will be described.

First, the foreign matter F is removed from the food H by the same method as described with reference to FIGS. 9A to 9D.

Next, the food H from which the foreign matter F has been removed is processed. In this case, the food H may be heated in an oven (not shown), a fryer, or the like, or may be steamed in a steamer, a microwave oven, a continuous boiling tank, or the like. When processing food H, a process selected according to the target processed food may be performed. For example, food H may be processed. Specifically, food H may be cut or sliced. When the food H is livestock meat or poultry meat, the food H may be ground into minced meat.

In this way, processed foods are produced.
