TECHNICAL FIELD The present invention relates to a linear foreign matter removing apparatus for removing linear foreign matter from foods such as marine products and agricultural products, and a method for producing dried marine or agricultural products from which linear foreign matter has been removed.

2. Description of the Related Art Conventionally, there has been known a foreign matter removing device for removing foreign matter from collected or harvested marine products, agricultural products, or the like. Such a foreign matter removing device is proposed in, for example, Japanese Patent Application Laid-Open No. 2007-43906 (Patent Document 1).

That is, Patent Document 1 discloses a washing tank having micropores made of punching metal or the like, and by putting collected raw algae and seawater into the washing tank and stirring and washing, the Microscopic contaminants (microscopic foreign matter) are discharged together with the drainage through the micropores. When such a foreign matter removing device is applied to agricultural products, for example, it is possible to remove soil, mud, insects, etc., and when it is applied to marine products, it is possible to remove minute shrimps, small fish, garbage, etc. can be done.

By the way, in the case of marine products, for example, foreign substances to be removed include not only the above-mentioned minute shrimps, small fish, garbage, etc., but also long and narrow foreign substances such as pieces of fish nets (net fibers) and fishing lines (line). Even in the case of agricultural products, contamination with long and thin foreign substances such as net fragments (net fibers) of agricultural nets and the like sometimes poses a problem.

JP-A-2007-43906

However, when circular micro holes are provided in the cleaning tank as in Patent Document 1, the diameter of the micro holes is smaller than the length dimension of the elongated linear foreign matter, making it difficult to remove the above-described elongated foreign matter. I was afraid. On the other hand, if the circular through-hole provided in the washing tank is formed with a diameter large enough to allow passage of elongated linear foreign matter, the through-hole becomes too large, and there is a risk that even the target seafood or agricultural products may be discharged from the washing tank. there were.

The problem to be solved by the present invention is a novel linear foreign matter removing apparatus and dried marine product from which linear foreign matter has been removed, which can efficiently remove elongated linear foreign matter from target dry marine products or agricultural products . Alternatively, it is to provide a method for producing agricultural products .

Hereinafter, preferred embodiments for understanding the present invention will be described. can be recognized and employed as independently as possible, and can also be employed in combination with any of the components described in other aspects as appropriate. Accordingly, the present invention can be implemented in various alternatives without being limited to the embodiments described below.

A first aspect is a linear foreign matter removing device for aligning and removing linear foreign matter contained in dry marine products or agricultural products , which has a peripheral wall and is rotatable around a central axis. an aligning device body, a plurality of elongated removal holes penetrating the peripheral wall in the thickness direction and extending in the central axis direction of the aligning device body and arranged in parallel and spaced apart from each other in the peripheral direction of the peripheral wall; wherein the aligning device main body repeatedly rolls the dry seafood or agricultural products containing the linear foreign matter placed on the peripheral wall by rotation about the central axis, and the rolling causes the linear foreign matter to roll. The linear foreign matter aligned in the central axis direction can be inserted through the plurality of removing holes penetrating the peripheral wall, and the dried seafood or agricultural products are arranged in the central axis direction. has a size that cannot be inserted through, and on the inner peripheral side of the peripheral wall of the aligning device main body, an area extending from the 0° position, which is the lower end in the vertical direction, to the 180° position in the rotational direction around the central axis is a space in which the linear foreign matter is allowed to drop due to gravity, and is not provided with other members, and a blower that blows air from the inner peripheral side to the outer peripheral side of the peripheral wall is provided in the peripheral wall of the aligning device main body. It is arranged in an area of 270° to 330° around the central axis on the inner peripheral side .

According to the linear foreign matter removing device of this aspect, the cylindrical aligning device body is rotatable around the central axis, and the peripheral wall of the aligning device body has a plurality of elongated removal holes extending in the direction of the central axis. It is provided so as to penetrate in the vertical direction. When the aligning device main body rotates around the central axis, the object to be removed placed on the peripheral wall moves upward as the peripheral wall rotates, and then falls downward due to gravity, repeating rolling. As a result, the linear foreign matter included in the foreign matter removal target is aligned so that the longitudinal direction of the linear foreign matter, which is a stable direction in which the vertical movement of the center of gravity of the linear foreign matter is reduced, is along the central axis direction. Become. That is, the aligning device main body performs the function of aligning the linear foreign matter in the direction of the central axis by rotating around the central axis. It should be noted that contact of the linear foreign matter with the removal hole extending in the central axis direction by repeated rolling can also align the linear foreign matter in the central axial direction.

Furthermore, the peripheral wall of the aligning device main body is provided with a plurality of elongated removal holes extending in the direction of the central axis. are doing. Therefore, the linear foreign matter aligned in the central axis direction by the rotation of the aligning device main body is inserted through the removal hole and removed to the outside of the peripheral wall, and the linear foreign matter can be removed from the foreign matter removal target. As described above, the linear foreign matter removing apparatus of this aspect has a function as an aligning device for aligning the linear foreign matter to be removed and a function as a separating device for separating the linear foreign matter to be removed from the foreign matter to be removed. , are combined in one device. These two functions make it possible to efficiently remove the linear foreign matter from the object to be removed.

In addition, since objects to be removed by the linear foreign matter removing apparatus of this aspect do not contain liquid, they are dry marine products, agricultural products, etc. that contain linear foreign matter to be removed. Therefore, it does not use water (seawater) like the above-mentioned Patent Document 1. Therefore, the apparatus for removing linear foreign matter in this embodiment can be applied to remove linear foreign matter from dried foods such as dried hijiki seaweed, wakame seaweed, whitebait, and dried sardines. In addition, agricultural products are also included in foreign matter removal targets that do not contain liquid, and the method can be advantageously used to remove linear foreign matter contained in agricultural products. In particular, by using the object to be removed in a dry state that does not contain liquid, entanglement between the object to be removed and the linear foreign matter can be eliminated or reduced. By repeatedly rolling the entire foreign matter removal target, the linear foreign matter contained in the foreign matter removal target can be more efficiently aligned in the central axis direction and removed from the removal hole. In addition, since the area from 0° to 180° in the rotation direction on the inner peripheral side of the peripheral wall of the cylindrical aligning device main body is a space where other members are not arranged, it moved upward along the peripheral wall. The object to be removed of foreign matter, including linear foreign matter, is not prevented from dropping due to gravity. Therefore, the linear foreign matter is stably aligned in the central axis direction by rolling. Further, the linear foreign matter to be removed is aligned in the direction of the central axis by blowing air from the blower arranged on the inner peripheral side of the aligning device main body, and the linear foreign matter can be quickly removed to the outside by passing through the removal hole. Moreover, since the blower is arranged in the range of 270° to 330° around the central axis, it is advantageous that the blower prevents the linear foreign matter from rolling due to the rotation of the aligning device main body and dropping due to gravity. suppressed.

A second aspect is the linear foreign matter removing device described in the first aspect, wherein one end side of the alignment device main body is inclined to be positioned higher than the other end side, and the linear foreign matter removing device is disposed at the one end side. provided with an inlet for the dried marine products or agricultural products containing linear foreign substances, and a recovery port for the dried marine products or agricultural products from which the linear foreign substances have been removed is provided at the other end. is.

According to this aspect, the aligning device main body is inclined so that one end side in the central axis direction is positioned higher than the other end side. It is possible to exhibit an alignment action by sliding against the linear foreign matter that is caught. That is, the linear foreign matter slides from one end side (upper side) of the aligning device main body toward the other end side (lower side) due to the action of gravity. Since the removal holes provided in the peripheral wall are elongated in the direction of the central axis, the linear foreign matter is aligned so that its longitudinal direction is in the direction of the central axis, which is the direction of less friction during sliding. Therefore, the inclination of the aligning device main body makes it possible to more advantageously align the linear foreign matter in the central axis direction. In addition, by adjusting the inclination angle, it becomes possible to set the processing amount and the processing accuracy according to the state of the foreign matter removal target. In addition, the objects to be removed from the foreign matter thrown into one end of the inclined aligning device main body are automatically sent by gravity to the recovery port provided at the other end of the aligning device main body. Continuous foreign matter removal processing becomes possible.

A third aspect is the linear foreign matter removing device according to the second aspect, wherein an inclination angle α of the central axis of the aligning device main body with respect to the ground plane is set to 5°≦α≦15°. , is a thing.

The inclination angle α of the center axis of the aligning device body with respect to the ground plane (horizontal plane) is preferably set to 5°≦α≦15°, more preferably 8°≦α≦12°. If the angle is less than 5°, it is difficult for the linear foreign matter to slide in the axial direction, and it is difficult to obtain an alignment action due to the sliding motion of the linear foreign matter. This is because it is difficult to obtain an alignment action due to repeated rolling of the linear foreign matter due to the rotation of the main body.

A fourth aspect is the linear foreign matter removing device according to any one of the first to third aspects, wherein the rotation speed of the aligning device main body around the central axis is 10 times/minute to 20 times/minute. It is a minute, it is a thing.

According to this aspect, since the rotational speed of the aligning device main body around the central axis is set in the range of 10 times/minute to 20 times/minute, the target linear foreign matter such as net fiber rolls. The aligning action of the can be produced more advantageously, and the removal of the linear foreign matter from the removal hole can be advantageously promoted. When the rotation speed is less than 10 rpm, it becomes difficult to obtain the action of aligning the linear foreign matter in the central axis direction due to repeated rolling, and when it is more than 20 rpm, the centrifugal force applied to the linear foreign matter is large. This is because it becomes difficult to obtain the alignment effect in the central axis direction due to the drop of the linear foreign matter due to gravity and the accompanying movement of the center of gravity.

A fifth aspect is the linear foreign matter removing device according to any one of the first to fourth aspects, wherein the width dimension of the plurality of removal holes in the circumferential direction is greater than the inner peripheral side of the peripheral wall.

According to this aspect, by evenly arranging a plurality of wedge wires extending in the central axis direction in the circumferential direction, the base of the wedge wires can be used to configure the peripheral wall of the cylindrical aligning device main body that functions as an aligner. In addition, the gap between the wedge wires can be used to form the linear foreign matter removing hole functioning as a separator at the same time, and the linear foreign matter removing apparatus of the present invention can be efficiently formed. Moreover, it is also possible to increase the circumferential width dimension of the removal hole from the inner peripheral side to the outer peripheral side of the peripheral wall by utilizing the cross-sectional shape of the wedge wire. can also be constructed more efficiently.

Furthermore, since both side edges of the bottom side of the wedge wire forming the inner surface of the peripheral wall extend in the central axis direction of the aligning device main body, the linear foreign matter is further prevented from rolling by being caught by the side edges of the bottom side of the wedge wire. can be generated efficiently. In addition, when combined with the second aspect, the sliding of the linear foreign matter from the top to the bottom in the tilting direction of the aligning device main body can be caused more efficiently by sliding along both side edges of the base of the wedge wire. . As a result, the effect of aligning the linear foreign matter in the direction of the central axis of the aligning device main body by rolling and sliding can be exhibited more advantageously, and the removal of the linear foreign matter from the removal hole can be facilitated.

By setting the circumferential width dimension of the inner peripheral side of each removal hole to a predetermined numerical range as in this aspect, it is possible to provide a linear foreign matter removing apparatus suitable for a desired foreign matter removal target. For example, by setting the circumferential width dimension of the inner peripheral side of each removal hole within the above range, it is possible to provide a linear foreign matter removing device suitable for hijiki.

According to an eighth aspect, in the linear foreign matter removing device according to any one of the first to seventh aspects, each of the above-mentioned The size of the aligning device main body in the removal hole in the direction of the central axis is ten times or more.

In this aspect, since each removal hole is formed to be elongated, it is possible to further reduce the possibility that the removal hole is too large for the elongated linear foreign matter to be removed. Further, by setting the circumferential width dimension of each removal hole small, even when a plurality of removal holes are provided in parallel in the circumferential direction, the plurality of removal holes can be formed in the peripheral wall with good space efficiency. It is also possible to provide more removal holes. As a result, the efficiency of foreign matter removal can be improved.

Hereinafter, in order to clarify the present invention more specifically, embodiments of the present invention will be described in detail with reference to the drawings.

First, FIG. 1 shows a linear foreign matter removing device 10 as a first embodiment of the present invention. This linear foreign matter removing device 10 includes an aligning device main body 12 that aligns linear foreign matter P contained in the foreign matter removal target O in the direction of the central axis L. As shown in FIG. The aligning device main body 12 has a substantially cylindrical shape as shown in FIGS. 2 to 4, and has a peripheral wall 14 that extends continuously over substantially the entire circumference in the circumferential direction. A plurality of removal holes 16 of a predetermined size are formed in the peripheral wall 14, and by rotating the alignment device main body 12 around the central axis L, as shown in FIG. The linear foreign matter P can be removed through the removal holes 16 from the placed foreign matter removal target O that does not contain liquid. That is, the linear foreign matter removing apparatus 10 of the present embodiment has a function as an aligning machine that aligns the linear foreign matter P and a function as a separator that separates and removes the linear foreign matter P from the foreign matter removal target O. It has both.

1 to 4 schematically show the linear foreign matter removing device 10 and the aligning device main body 12, and the specific structures of the linear foreign matter removing device 10 and the aligning device main body 12 are not limited. . That is, in FIGS. 1 to 4, there are cases where, for example, the removal hole 16, the later-described connecting portion 30 (wedge wire), and the like are exaggeratedly illustrated in terms of circumferential dimension and radial dimension. Further, in the following description, the central axis direction and the length direction refer to the horizontal direction in FIG. 1 along which the central axis L of the alignment device main body 12 extends.

More specifically, the linear foreign matter removing device 10 includes a support base 18 that supports the aligning device main body 12 and a motor 20 that rotates the aligning device main body 12 . One end of a rotating shaft 22 is connected to the motor 20 , and the other end of the rotating shaft 22 is supported by the support base 18 . As a result, the rotating shaft 22 is rotatable around the central axis by being driven by the motor 20 . Further, the rotating shaft 22 is inserted substantially coaxially with the alignment device main body 12 , and the rotating shaft 22 and the alignment device main body 12 are fixedly connected.

Although the fixing structure between the rotating shaft 22 and the alignment device body 12 is not limited, for example, the rotating shaft 22 and annular plate portions 26, 26, which are provided at both ends in the length direction of the alignment device body 12, are aligned. It may be connected by a plurality of (four in FIGS. 1 and 2) connecting rods 24 extending in the radial direction of the device main body 12 . Such connecting rods 24 can be provided, for example, at substantially equal intervals in the circumferential direction.

By driving the motor 20 in the linear foreign matter removing device 10 having such a structure, the aligning device main body 12 rotates around the central axis L together with the rotating shaft 22 .

The rotation speed of the alignment device main body 12 around the central axis L is not limited, but is preferably 10 to 20 times/minute, more preferably 12 to 16 times/minute. minutes. If the rotational speed of the aligning device main body 12 around the central axis L is less than 10 times/min, the aligning device main body 12, which will be described later, may not sufficiently exhibit the effect of aligning the linear foreign matter P. Further, if the rotational speed of the aligning device main body 12 around the central axis L is higher than 20 times/min, the centrifugal force acting on the foreign matter removal target O including the linear foreign matter P becomes too large, and the foreign matter removal target O due to gravity becomes too large. There is a risk that the dropping and stirring of O, and the accompanying effect of aligning the linear foreign matter P, etc., may not be sufficiently exhibited. In this embodiment, the rotational speed of the alignment device main body 12 around the central axis L is 14 times/minute.

A plurality of removal holes 16 are formed in the peripheral wall 14 of the aligning device main body 12 so as to penetrate the peripheral wall 14 in the thickness direction. In this embodiment, each removal hole 16 extends in the central axis direction of the alignment device main body 12 . Also, the removal holes 16 are provided in parallel and spaced apart from each other in the circumferential direction of the peripheral wall 14 . In particular, in this embodiment, each removal hole 16 has the same shape.

In particular, in this embodiment, annular plate portions 26 , 26 are provided at both longitudinal ends of the peripheral wall 14 of the alignment device main body 12 . In addition, a plurality of annular reinforcing members 28 are provided in an intermediate portion in the length direction of the aligning device body 12 (peripheral wall 14), that is, between the two annular plate portions 26, 26 facing each other. ) has been improved. The plurality of reinforcing members 28 are spaced apart from each other in the longitudinal direction of the alignment device main body 12 (peripheral wall 14) and provided at approximately equal intervals. A plurality of removal holes 16 are provided between the reinforcing members 28 , 28 adjacent in the length direction of the aligning device main body 12 .

Specifically, connecting portions 30 for connecting the reinforcing members 28 , 28 are provided between the reinforcing members 28 , 28 adjacent in the length direction of the alignment device main body 12 (peripheral wall 14 ). In this embodiment, a plurality of connecting portions 30 extending in the length direction (the direction of the central axis) of the aligning device main body 12 are provided at substantially equal intervals in the circumferential direction. A removal hole 16 extending in the longitudinal direction of the device body 12 is formed. In addition, in the enlarged view on the upper right of FIG. 4, the removal hole 16 is shown in gray for easy understanding.

The annular plate portion 26, the reinforcing member 28, and the connecting portion 30 are each made of metal such as iron, and are fixed to each other by welding or the like so that the aligning device main body 12 is integrally formed. there is In addition, in this embodiment, the inner diameter of the peripheral wall 14 including the annular plate portion 26, the reinforcing member 28, and the connecting portion 30 is substantially constant in the length direction of the peripheral wall 14. As shown in FIG. In particular, in this embodiment, the inner diameter dimension of the peripheral wall 14 is constant over the entire length in the central axis L direction. That is, the inner diameter dimension of the annular plate portion 26, the inner diameter dimension of the reinforcing member 28, and the diameter of the virtual circle connecting the inner peripheral end portions of the plurality of connecting portions 30 are substantially equal.

In particular, in the present embodiment, as shown in FIG. 3, the cross-sectional shape of the connecting portion 30 is approximately an isosceles triangle, and one of the vertices is located at the outer peripheral edge of the peripheral wall 14. is positioned at the inner peripheral edge of the peripheral wall 14 . That is, in the present embodiment, the connecting portion 30 is made of a wedge wire. Therefore, the peripheral wall 14 is configured to include a plurality of wedge wires that are evenly arranged at predetermined intervals in the circumferential direction and extend in a triangular cross-section in the direction of the central axis L, as also shown in the cross-sectional view of FIG. As such, each wedge wire is arranged such that the base of the triangular cross-section forms the inner surface of the peripheral wall 14 . Since each removal hole 16 is formed by a gap between the connecting portions 30, 30 (wedge wires) adjacent in the circumferential direction, the circumferential width dimension A (Fig. 3 and 4), the circumferential width dimension B (see FIG. 3) on the outer peripheral side of the peripheral wall 14 is larger.

Also, the lengthwise dimension C (see FIG. 4) of the removal hole 16 is made larger than the circumferential width dimension A of the inner peripheral side of the removal hole 16 . The lengthwise dimension C of the removal hole 16 is not limited, but may be, for example, 10 times or more, or 20 times or more, the circumferential width dimension A of the inner peripheral side of the removal hole 16 . 4, the removal hole 16 is elongated in the central axis direction of the alignment device main body 12 when viewed in the radial direction (for example, when viewed from the inner peripheral side to the outer peripheral side of the peripheral wall 14). It may be substantially rectangular. That is, in the present embodiment, the inner circumferential width dimension A and the outer circumferential width dimension B of each removal hole 16 are substantially constant in the central axis L direction. Note that the circumferential width dimension A and the length dimension C of the inner peripheral side of each removal hole 16 are such that the elongated linear foreign matter P, which will be described later, can be inserted in a state aligned in the central axis L direction of the alignment device main body 12 . There is, and the size is set such that the foreign matter removal target O cannot be inserted.

The circumferential width dimension A on the inner circumferential side, the circumferential width dimension B on the outer circumferential side, and the lengthwise dimension C of these removal holes 16 are determined by the size of the foreign matter removal object O to be applied, the size of the linear foreign matter P to be removed, and the like. However, for example, when the foreign matter removal target O is dried hijiki, the circumferential width A of the removal hole 16 on the inner circumference side is preferably set to 0.8 mm or more. be. This is because if the circumferential width dimension A of the removal hole 16 on the inner peripheral side is less than 0.8 mm, the width dimension becomes too small, which may make it difficult to remove the linear foreign matter P. Moreover, it is preferable that the circumferential width dimension A of the removal hole 16 on the inner peripheral side is 1.2 mm or less. If the circumferential width A of the removal hole 16 on the inner circumference side is larger than 1.2 mm, the removal hole 16 becomes too large for the linear foreign matter P, and the target foreign matter removal target O (hijiki) passes through the removal hole 16. ) may also fall easily.

Further, the linear foreign matter removing device 10 of this embodiment includes a suction device 32 that exerts a suction force from the outer peripheral side of the peripheral wall 14 of the aligning device main body 12, as shown in FIG. That is, the linear foreign matter removing apparatus 10 may include a receiving portion 34 that receives the removed linear foreign matter P and has, for example, a substantially box-like shape, a substantially dish-like shape, or a substantially gutter-like shape. In the linear foreign matter removing device 10 of the present embodiment, the receiving portion 34 is provided below the aligning device main body 12 because the linear foreign matter P falls downward due to gravity. For example, by opening a tube or the like extending from the suction device 32 in the bottom surface of the receiving part 34 , the negative pressure of the suction device 32 can be applied to the aligning device main body 12 from outside (below) the aligning device main body 12 . . For example, a filter or the like may be provided on the path from the receiving portion 34 to the suction device 32 to prevent the linear foreign matter P from entering the suction device 32 . Further, the shape of the receiving part 34 is not limited, and for example, it may spread flat under the aligning device main body 12, or it may spread in an arcuate cross-section so as to cover the lower half of the aligning device main body 12. may Furthermore, such an aspirator 32 may be mounted on the support base 18 or may be provided outside the support base 18 .

As shown in FIG. 3, a foreign object to be removed O is placed inside the aligning device body 12 of the linear foreign matter removing device 10 having such a structure, that is, between the peripheral wall 14 and the rotating shaft 22 in the radial direction. to drive the motor 20. As a result, the rotating shaft 22 and the alignment device main body 12 (peripheral wall 14) are rotated around the central axis L, for example, in the direction of the white arrow in FIG. As a result, the object to be removed O sticks to the inner peripheral surface of the aligning device main body 12 (peripheral wall 14) and moves upward together with the aligning device main body 12 (peripheral wall 14), as indicated by a thick two-dot chain line. After rising to a height of , it falls downward due to the action of gravity. This rolling motion is repeated to agitate the foreign matter removal target O. As shown in FIG. Alternatively, the object to be removed O is agitated by vibration or the like caused by the rotation of the aligning device main body 12 (peripheral wall 14) without substantially moving with respect to the rotation of the aligning device main body 12 (peripheral wall 14). The manner of agitating the foreign matter removal target O differs depending on the type and condition of the foreign matter removal target O (how dry it is, etc.). The foreign matter removal target O is agitated with the rotation.

The linear foreign matter P is separated from the foreign matter removal target O by stirring or vibrating the foreign matter removal target O in this way. It should be noted that in the state immediately after placing the foreign matter removal object O on the alignment device main body 12, the elongated linear foreign matter P contained in the foreign matter removal target O extends in various directions, but the alignment device main body 12 ( By rotating the peripheral wall 14) and agitating as described above, the direction in which the elongated linear foreign matter P extends changes every moment. When the direction in which the elongated linear foreign matter P extends coincides with the central axis direction of the aligning device main body 12, that is, when the elongated linear foreign matter P extends in the direction perpendicular to the paper surface of FIG. The rotational force around the central axis L of the aligning device main body 12 generated causes the linear foreign matter P to rotate about the central axis along the direction in which the linear foreign matter P extends, and the linear foreign matter P extends in the direction of the aligning device main body. 12, the state of being substantially aligned with the direction of the central axis L is likely to continue. As a result, the direction in which the linear foreign matter P extends coincides with the length direction of the removal hole 16, and the linear foreign matter P falls downward through the removal hole 16, thereby removing the linear foreign matter P from the foreign matter removal target O. can do.

In the linear foreign matter removing apparatus 10 of the present embodiment having the structure described above, the elongated linear foreign matter P can be efficiently removed from the foreign matter removal target O through the removal hole 16 provided through the peripheral wall 14. can be done. That is, for example, when an elongated linear foreign matter P is included in the foreign matter removal target O so as to extend in a direction orthogonal to the central axis L direction of the alignment device main body 12, the foreign matter removal target O is initially agitated by the alignment device. As the main body 12 rotates, the direction in which it extends greatly changes. Then, when the length direction of the linear foreign matter P coincides with the direction of the central axis L of the aligning device main body 12, the elongated linear foreign matter P is rotated around the central axis L of the aligning device main body 12, for example, as shown in FIG. , rotates about the direction in which the linear foreign matter P extends along the direction of the central axis L of the aligning device main body 12 as a rotation axis, as indicated by a small two-dot chain line arrow. Further, even if the linear foreign matter P moves along the inner peripheral surface of the aligning device main body 12 (peripheral wall 14) together with the foreign matter removal target O, the direction in which it extends does not change significantly. Therefore, once the foreign matter removal target O is agitated and the length direction of the linear foreign matter P coincides with the central axis direction of the aligning device main body 12, the length direction of the linear foreign matter P does not change much more. By continuing the stirring, the ratio of the linear foreign matter P extending in the direction of the central axis L of the alignment device main body 12 in the foreign matter removal target O increases. With further stirring, the linear foreign matter P is displaced in the vertical direction within the foreign matter removal target O without substantially changing its length direction, and is separated from the foreign matter removal target O into the removal hole 16 . The linear foreign matter P that has entered is removed to the outside of the alignment device main body 12 (peripheral wall 14 ) through the removal hole 16 .

In the following, the action of aligning the linear foreign matter P by rolling will be described in more detail. As described above, when the aligning device main body 12 is rotated around the central axis L in a state where the foreign matter removal target O is placed on the aligning device main body 12, the foreign matter removing target O rises and falls and/or the aligning device main body 12 The linear foreign matter P is agitated in the foreign matter removal target O by repeatedly rolling due to vibrations of the foreign matter. At that time, if the direction of the central axis of the linear foreign matter P is different from the direction of the central axis L of the aligning device main body 12, the linear foreign matter P rolls in the foreign matter removal target O, causing the vertical displacement of the center of gravity of the linear foreign matter P. quantity increases. On the other hand, the linear foreign matter P is stirred in the foreign matter removal target O, and the central axis direction of the linear foreign matter P coincides with the central axis L direction of the aligning device main body 12, so that the central axis L of the aligning device main body 12 is aligned. A rotating force can be applied to the linear foreign matter P as a rotation around the central axis, and the amount of vertical displacement of the center of gravity of the linear foreign matter P can be kept small. Here, since an object is generally pulled downward by the action of gravity, it is more stable when the amount of upward displacement is small, in other words, when the amount of vertical displacement is small. Therefore, when the linear foreign matter P in the foreign matter removal object O coincides with the central axis direction of the linear foreign matter P and the central axis L direction of the aligning device main body 12, this state is stabilized and this stable state is maintained. It will be done. By continuing the rotation of the aligning device main body 12 around the central axis L, the ratio of the stable state in which the central axis direction of the linear foreign matter P coincides with the central axis L direction of the aligning device main body 12 gradually increases. The direction of the central axis of the foreign matter P is aligned with the direction of the central axis L of the aligning device main body 12 .

The action of aligning the linear foreign matter P by the aligning device main body 12 not only suppresses the amount of vertical displacement of the linear foreign matter P due to gravity as described above, but also removes the linear foreign matter P extending in the direction of the central axis L of the aligning device main body 12, for example. It is also realized by the side edges of the holes 16 . That is, the linear foreign matter P stirred in the foreign matter removal target O is caught in the side edge of the removal hole 16 extending in the central axis L direction of the alignment device main body 12, so that the linear foreign matter P is oriented in the central axis L direction. By continuing the rotation of the aligning device main body 12 around the central axis L, the central axis direction of the linear foreign matter P can be gradually aligned with the central axis L direction of the aligning device main body 12 . In addition, as described above, the mode of stirring the foreign matter removal target O varies depending on the type and state of the foreign matter removal target O. centrifugal force can be exerted on the object to be removed O including the linear foreign object P, and as the aligning device main body 12 rotates around the central axis L, it moves upward together with the peripheral wall 14 and falls downward due to the action of gravity. It is possible to stably obtain the stirring effect of the object O for removing foreign matter. In other words, it is possible to prevent the foreign matter removal target O from being agitated without substantially moving it, and to agitate it more dynamically, thereby promoting a change in the orientation of the linear foreign matter P.

After the aligning device main body 12 is rotated around the central axis L for a predetermined time or a predetermined number of times, the rotation of the aligning device main body 12 is stopped to obtain the foreign matter removal target O from which the linear foreign matter P has been removed. be able to.

That is, the method of removing the linear foreign matter P from the foreign matter removal target O using the linear foreign matter removing apparatus 10 of the present embodiment, in short, the method of manufacturing the foreign matter removal target O from which the linear foreign matter P has been removed will be described below. includes steps (1) and (2).
(1) By rotating the aligning device main body 12 around the central axis L, the foreign matter removal target O including the linear foreign matter P is repeatedly rolled, and the linear foreign matter P is aligned in the central axis L direction by this rolling. Alignment step (2) A removal step of removing the linear foreign matter P aligned in the alignment step through a plurality of removal holes 16

In the linear foreign matter removing device 10 of the present embodiment, as the aligning device main body 12 rotates about the central axis L, the long and narrow linear foreign matter P in the foreign matter removal target O gradually extends along the length of the aligning device main body 12 . Therefore, by providing the removal hole 16 so as to extend in the central axis L direction of the aligning device main body 12, the linear foreign matter P can be efficiently removed from the foreign matter removal target O.

That is, the linear foreign matter removing device 10 of the present embodiment includes an aligning device main body 12 and functions not only as a separating device or a foreign matter removing device but also as an aligning device. As a result, the orientation of the linear foreign matter P in the foreign matter removal object O can be positively aligned in the direction of the central axis L of the alignment device main body 12 . As a result, removal of the linear foreign matter P through the removal holes 16 can be achieved more efficiently.

Further, the removal of the linear foreign matter P by the linear foreign matter removing apparatus 10 of the present embodiment does not use water (including seawater, etc.) as described in Patent Document 1, but uses a conventionally known filter. It is also different from solid-liquid separation. Therefore, in the linear foreign matter removing apparatus 10 of the present embodiment, the foreign matter removal target O is dry food or the like that does not contain liquid. In particular, since the foreign matter removal target O does not contain liquid, the foreign matter removal target O shrinks compared to the foreign matter removal target O in the wet state containing the liquid, and the linear foreign matter P is removed from the foreign matter removal target O. easier to separate. Therefore, the linear foreign matter P can be more efficiently removed from the foreign matter removal target O in the dry state while leaving non-defective products.

Further, in the linear foreign matter removing device 10 of the present embodiment, the rotational speed of the alignment device main body 12 around the central axis L is set within a range of 10 to 20 times/minute. As a result, in the aligning device main body 12, the objects to be removed O can be efficiently agitated, and the alignment of the linear foreign substances P and the removal of the linear foreign substances P through the removal holes 16 can be stably performed. .

Furthermore, in this embodiment, the circumferential width dimension B on the outer peripheral side of the removal hole 16 is larger than the circumferential width dimension A on the inner peripheral side. As a result, the linear foreign matter P that has entered the removal hole 16 can easily escape to the outside of the peripheral wall 14, and the removal hole 16 can be prevented from being clogged.

The removal holes 16 whose circumferential width dimension B on the outer circumferential side is larger than the circumferential width dimension A on the inner circumferential side are located between the removal holes 16, 16 adjacent in the circumferential direction. It can be simply formed by having 30 consist of a wedge wire with a substantially triangular cross-section. Each removal hole 16 extends in the direction of the central axis L of the aligning device main body 12, and the agitation of the foreign matter removal target O causes the linear foreign matter P to be removed from the side edges of each removal hole 16, that is, the side edges of the wedge wire. Since the orientation of the linear foreign matter P is aligned in the direction of the central axis L of the aligning device main body 12 by being caught by the wedge wire forming the peripheral wall 14, the linear foreign matter P is aligned.

Furthermore, the removal hole 16 has a length dimension C larger than a circumferential width dimension A, and has, for example, a substantially rectangular shape when viewed from the inner periphery side to the outer periphery side. This prevents the removal hole 16 from becoming too large when removing the elongated linear foreign matter P. In particular, the removal hole 16 can be formed in an elongated shape by setting the length direction dimension C of the removal hole 16 to be ten times or more the circumferential width dimension A, for example. This makes it easier to arrange the removal holes 16 side by side in the circumferential direction, and by arranging more removal holes 16 in the circumferential direction, it is possible to improve the removal efficiency of the linear foreign matter P. Note that the circumferential width dimension A and the length dimension C of the removal hole 16 are not limited, and can be appropriately set according to the foreign matter removal target O and the linear foreign matter P. FIG.

Further, in this embodiment, since the suction device 32 that exerts a suction force from the outside on the alignment device main body 12 is provided, the removal of the linear foreign matter P through the removal hole 16 can be achieved more efficiently. .

Furthermore, in this embodiment, the inner diameter dimension of the peripheral wall 14 of the alignment device main body 12 is constant over the entire length in the central axis L direction. As a result, when the aligning device main body 12 is rotated around the central axis L to agitate the foreign object removal target O, agitation does not occur partially compared to, for example, the case where the inner peripheral surface of the peripheral wall is provided with protrusions. It is possible to substantially uniformly agitate the object O for foreign matter removal. Furthermore, alignment of the linear foreign matter P is prevented from being hindered by colliding with the protrusions on the inner peripheral surface. As a result, alignment of the linear foreign matter P by the aligning device main body 12 and removal of the linear foreign matter P through the removal holes 16 can be stably realized.

Furthermore, according to the method of manufacturing the object to be removed O from which the linear foreign matter P has been removed, using the linear foreign matter removing device 10 of the present embodiment, the aligning device main body 12 is rotated around the central axis L. , the linear foreign matter P can be aligned in the direction of the central axis L, and there is no need to perform a special operation when aligning the linear foreign matter P in the direction of the central axis L. Removal can be accomplished quickly.

Next, FIGS. 5 to 7 show a linear foreign matter removing device 40 as a second embodiment of the present invention. The overall configuration of the linear foreign matter removing device 40 in this embodiment is the same as that of the linear foreign matter removing device 10 in the first embodiment, but there are some differences. In addition to describing in detail the differences from the first embodiment, in the linear foreign matter removing apparatus 40 of the present embodiment, substantially the same members and parts as those of the first embodiment are indicated in the figure as the first embodiment. A detailed description is omitted by attaching the same reference numerals as the form. The present applicant has made a prototype of the linear foreign matter removing device 40 according to this embodiment, and a photograph of the prototype is shown in FIG.

That is, in the first embodiment, the rotation shaft 22 inserted through the alignment device body 12 is rotated by the motor 20 to rotate the alignment device body 12 around the central axis L, but in the present embodiment, 5 and 7, a plurality of driving wheels 42 having a central axis L' in the same direction as the central axis L of the aligning device main body 12 are aligned on the outer peripheral side of the aligning device main body 12, as indicated by the two-dot chain lines. It is arranged in contact with the apparatus main body 12 . By rotating these plurality of driving wheels 42 synchronously in the same circumferential direction (see the small two-dot chain line arrow in FIG. 5), for example, by a motor (not shown), the aligning device main body 12 can be moved to the central axis. It is designed to rotate around L. In this embodiment, a plurality of driving wheels 42 are provided on the outer peripheral surfaces of reinforcing members 28, 28 integrally formed with annular plate portions 26, 26 provided at both ends of the alignment device main body 12 in the direction of the central axis L. arranged to abut. Such a drive wheel 42 is provided, for example, on the support base 18 that supports the alignment device main body 12 . Thus, in this embodiment, the member for rotating the alignment device main body 12 is provided outside the alignment device main body 12, and other members are substantially not arranged inside the alignment device main body 12. .

Further, in this embodiment, as shown in FIG. 7, when the linear foreign matter removing device 40 is used, the aligning device main body 12 is inclined with respect to the ground plane 43 extending in the horizontal direction. Specifically, as shown in FIG. 7, the central axis L of the aligning device main body 12 is inclined at an inclination angle α with respect to the horizontal line F parallel to the ground plane 43 . Although the magnitude of the inclination angle α is not limited, it is preferably 5°≦α≦15°, more preferably 8°≦α≦12°. If the inclination angle α is less than 5°, there is a possibility that the linear foreign matter P cannot be sufficiently aligned by the sliding action described later. On the other hand, if the inclination angle α is larger than 15°, the sliding speed of the linear foreign matter P becomes too fast, the alignment effect of the linear foreign matter P cannot be sufficiently obtained, or the linear foreign matter P cannot pass through the removal hole 16 . may not be sufficiently removed. In this embodiment, the inclination angle α is set to 10°.

By arranging the aligning device main body 12 inclined with respect to the horizontal direction, one end side (the left end side in FIG. 7) of the aligning device main body 12 is higher than the other end side (the right end side in FIG. 7). An inlet 44 for the foreign matter to be removed O including the linear foreign matter P is provided on the upper left end side (one end side) of the aligning device main body 12 in FIG. A recovery port 46 for the foreign matter removal target O from which the linear foreign matter P has been removed is provided on the right end side (the other end side) in FIG. Although the shapes of the input port 44 and the recovery port 46 are not limited, they are substantially gutter-shaped in the present embodiment. That is, in the present embodiment, the foreign matter removal target O including the linear foreign matter P moves from left to right in FIG. The bottom surface of the input port 44 and the recovery port 46 may be a belt conveyor so that the object to be removed O located above the input port 44 and the recovery port 46 is automatically sent out in the moving direction. Also, the aligning device main body 12 can be tilted at a predetermined angle by, for example, raising the left end in FIG. 7 or lowering the right end in use. Conventionally known elevating means such as a hydraulic jack can be employed for such elevating and lowering of the aligning device main body 12 .

Furthermore, in the present embodiment, a blower 48 is inserted into the peripheral wall 14 of the aligning device main body 12 from the right side in FIG. In particular, in this embodiment, when the vertical direction downward in the cross section in FIG. , i.e., the lower left region in the cross section in FIG. It should be noted that the fact that the blower 48 is arranged within the range of 270° to 330° means that, for example, the central axis of the tubular portion of the blower 48 that is inserted into the alignment device main body 12 and extends in the direction of the central axis L is 270° to 330°. , and the entire blower 48 need not be arranged within the range of 270° to 330°. This blower 48 is provided with an opening (not shown) obliquely downward to the left in FIG. Air can be blown in the direction indicated by the white arrow. The amount of insertion of the blower 48 into the aligning device main body 12 in the direction of the central axis L is made relatively small, so that the objects to be removed O and the alignment of the linear foreign substances P can be stirred without problems. In particular, in the cross section shown in FIG. 5, the blower 48 is provided on the inner peripheral side of the peripheral wall 14 of the aligning device main body 12 in an area within the range of 270° to 330° in the rotational direction around the central axis L. A space 50 in which other members are not arranged is at least a region from 0° (lower) to 180° (upper).

In the linear foreign matter removing device 40 of the present embodiment, in addition to the rolling action of the linear foreign matter P as in the first embodiment, the sliding action of the linear foreign matter P also causes the linear foreign matter P to move in the central axis L direction. alignment is achieved. In the following, the operation of aligning the linear foreign matter P by sliding will be described in detail. That is, as described above, since the aligning device main body 12 is inclined with respect to the horizontal direction, the linear foreign matter P moves in the direction of the central axis L while being agitated by the rotation and vibration of the aligning device main body 12. . Here, when the direction of the central axis of the linear foreign matter P is different from the direction of the central axis L of the aligning device main body 12, the contact area between the linear foreign matter P and the aligning device main body 12 in the direction intersecting the central axis L is growing. As a result, the friction between the linear foreign matter P and the aligning device main body 12 increases when the linear foreign matter P moves in the direction of the central axis L, and the linear foreign matter P moves along the central axis L direction of the aligning device main body 12 . It is difficult for slippage to occur. On the other hand, when the direction of the central axis of the linear foreign matter P and the direction of the central axis L of the aligning device main body 12 coincide with each other due to the rolling operation described in the first embodiment, the linear foreign matter P in the direction intersecting with the central axis L and the contact area with the aligning device main body 12 becomes smaller. As a result, the friction between the linear foreign matter P and the aligning device main body 12 when the linear foreign matter P moves in the direction of the central axis L is reduced, and the linear foreign matter P moves along the central axis L direction of the aligning device main body 12 . slippage is more likely to occur. As a result, the direction of the linear foreign matter P is gradually aligned in the direction of the central axis L by rolling and sliding of the linear foreign matter P, and the linear foreign matter P is removed through the removal hole 16 .

Further, in this embodiment, a blower 48 that blows air from the inner peripheral side of the peripheral wall 14 toward the outer peripheral side is provided near the end (the right end in FIG. 7) of the alignment device main body 12 on the recovery port 46 side. there is The blower 48 is provided with an opening toward the outer periphery, through which air is blown toward the foreign matter removal target O, and the linear foreign matter P can be removed from the foreign matter removal target O through the removal holes 16. . As a result, for example, the linear foreign matter P is removed in the direction of 315° (lower left in FIG. 5) in the direction of rotation of the alignment device main body 12 about the central axis L in FIG. It is possible to recover the foreign matter removal target O that has been removed from the 0° direction (lower side in FIG. 5). Although not shown, the suction device 32 and the receiving part 34 in the first embodiment can also be used in this embodiment. It is also possible to remove the linear foreign matter P.

In particular, in this embodiment, the blower 48 is provided within a range of 270° to 330° in the rotation direction of the alignment device main body 12 about the central axis L in FIG. A space 50 in which other members are not provided is provided. Therefore, in this space 50, the object to be removed O, which has risen along the inner peripheral surface of the peripheral wall 14, can drop by gravity, and the agitation of the object to be removed O and the alignment of the linear foreign object P are stably realized. can be

Further, in this embodiment, the inclination angle α of the alignment device main body 12 with respect to the horizontal direction is set to 5°≦α≦15°. As a result, not only can the linear foreign matter P be aligned by the sliding motion, but also the foreign matter removal target O can be automatically moved from the input port 44 to the recovery port 46, thereby improving the efficiency of the foreign matter removing operation. .

In particular, in this embodiment, the linear foreign matter P is aligned in the direction of the central axis L of the aligning device main body 12 by combining the rolling action and the sliding action of the linear foreign matter P. In short, in this embodiment, by adopting a combination of the inclination angle α with respect to the horizontal direction of the alignment device main body 12 within a specific range and the rotational speed of the alignment device main body 12 within a specific range, better alignment can be achieved. It was effective. That is, for a suitable combination of the tilt angle α and the rotation speed, for example, when the tilt angle α increases (that is, when the rotation speed relatively decreases), the linear foreign matter P is aligned in the direction of the central axis L due to the rolling action. There is a risk that it will slide to the recovery port 46 before it is removed. Further, for a suitable combination of the inclination angle α and the rotation speed, for example, when the rotation speed increases (that is, when the inclination angle α becomes relatively small), the action of centrifugal force is likely to occur, for example, the downward movement due to gravity. will not easily fall, and there is a risk that the foreign matter removal target O will not be sufficiently agitated or aligned. A preferable rotation speed of the aligning device main body 12 in this embodiment is the same as that in the first embodiment, preferably 10 times/minute to 20 times/minute.

Then, the method of manufacturing the foreign matter removal target O from which the linear foreign matter P has been removed using the linear foreign matter removing apparatus 40 of the present embodiment includes (1) the alignment step and (2) described in the first embodiment. In addition to the removing step, the following steps (3) to (5) are included.
(3) The foreign matter removal target O including the linear foreign matter P is introduced into the input port 44 , and the foreign matter removal target O including the linear foreign matter P is slid in the tilted aligning device main body 12 to the recovery port 46 . Step (4) of automatically feeding the object O from which the linear foreign matter P has been removed and recovering it from the recovery port 46. Step (5) of installing on the recovery port 46 side of the aligning device main body 12 By blowing air from the inner peripheral side of the peripheral wall 14 to the outer peripheral side with the blower 48 in the removing step of (2) above, the aligning step of (1) above A step of removing aligned linear foreign matter P by pushing out from the inner peripheral side of the plurality of removal holes 16 to the outer peripheral side.

Since the method of manufacturing the foreign matter removal target O from which the linear foreign matter P has been removed using the linear foreign matter removing apparatus 40 of the present embodiment includes the above step (3), the linear foreign matter is removed by the sliding motion. In addition to aligning P in the direction of the central axis L, the foreign matter removal target O can be automatically sent from the input port 44 to the recovery port 46, continuous foreign matter removal processing becomes possible, and linear foreign matter P can be removed. Removal efficiency is improved. Further, since the method for manufacturing the object to be removed O from which the linear foreign matter P has been removed using the linear foreign matter removing apparatus 40 of the present embodiment includes the above steps (4) and (5), The removal of the linear foreign matter P through the removal holes 16 is promoted by blowing air from the blower 48, and the removal efficiency of the linear foreign matter P is improved.

Alternatively, the circumferential width dimension A on the inner circumference side of the removal hole may be larger than the circumferential width dimension B on the outer circumference side of the removal hole.
