  The present invention has been made to solve the above-described problems, and one of the objects of the present invention is to provide an entangled component separating apparatus capable of easily separating parts entangled with each other.

In order to achieve the above-described object, according to one aspect of the present invention, the entangled component separation device includes a first opening serving as a part introduction port and a second opening serving as a part discharge port.

According to this aspect, the inner wall of the drum has an inclined surface whose inner diameter increases in the direction from the first opening to the second opening, and the lowermost end of the first opening is lower than the lowermost end of the second opening. Since the drum is rotated around a rotation axis that intersects the direction of gravity in a high state, the parts introduced into the first opening move toward the second opening. On the other hand, a part group consisting of a plurality of parts intertwined with other parts among the parts introduced into the first opening is entangled with one of the plurality of first protrusions, so the part group moves to the second opening. You can avoid it. In addition, a part group entangled with any of the plurality of first protrusions is lifted upward by the rotation of the drum and then falls by gravity. For this reason, entanglement with other parts may be canceled among the plurality of parts included in the part group due to falling. In addition, since the plurality of second protrusions arranged on the second opening side than the plurality of first protrusions is provided, the number of parts entangled in stages can be reduced, so that the parts entangled efficiently Can be separated.

According to this aspect, the parts group is simultaneously entangled with two or more of the plurality of first protrusions as the drum rotates, so that the parts group can be prevented from moving to the second opening. Further, since the parts group receiving the force in the direction of gravity receives the force from multiple directions as the drum rotates, each of the plurality of parts in the part group can be separated from the parts group.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the following description, the same parts are denoted by the same reference numerals. Their names and functions are also the same. Therefore, detailed description thereof will not be repeated.

  FIG. 1 is a left side view showing an example of the entangled component separation device in the present embodiment. Referring to FIG. 1, the entangled component separation device 1 includes a drum 10 and a drive mechanism 20 that rotates the drum 10. The drum 10 includes a first opening 11 serving as a part introduction port, a second opening 13 serving as a part discharge port, and an annular flange 15 extending from an outer wall thereof. The drive mechanism 20 rotatably holds the drum 10 in a state where the lowermost end of the first opening 11 is higher than the lowermost end of the second opening 13. Here, the drive mechanism 20 holds the drum 10 in a state in which the central axis passing through the center of the cross section of the drum 10 is horizontal intersecting the weight direction.

  FIG. 2 is a front view of the entangled component separator. FIG. 2 is a view of the entangled component separator 1 as viewed from the second opening 13 side. FIG. 3 is a plan view of the entangled component separator. 1 to 3, the drive mechanism 20 includes a motor 21, a drive belt 23, a first roller 24, a second roller 25, stoppers 26 and 27, and a base 29.

  The motor 21, the first roller 24, and the second roller 25 are fixed to the base 29 so that the respective rotation axes are parallel to each other. The distance from the base 29 of the rotating shaft of each of the first roller 24 and the second roller 25 is the same. The first roller 24 is connected by a pulley 22 connected to the drive shaft of the motor 21 and a drive belt 23, and the rotational force of the motor 21 is transmitted to the first roller 24.

  The drum 10 is placed on the first roller 24 and the second roller 25. For this reason, the rotating shaft 39 of the drum 10 is parallel to the rotating shafts of the first roller 24 and the second roller 25, and the distance from the outer wall of the drum 10 is constant. Since the first roller 24 and the second roller 25 hold the drum 10 in a state where the central axis passing through the cross-sectional center of the drum 10 is horizontal, the rotation shaft 39 coincides with the central axis passing through the cross-sectional center of the drum 10, It is horizontal.

  When the motor 21 is driven while the drum 10 is placed on the first roller 24 and the second roller 25, the rotation of the motor 21 is transmitted to the first roller 24 via the drive belt 23. When the first roller 24 rotates, the drum 10 rotates due to the frictional force of the portion where the first roller 24 contacts the outer wall of the drum 10. Further, when the drum 10 is rotated, the second roller 25 is rotated by the frictional force of the portion where the drum 10 is in contact with the second roller 25.

  Each of the stoppers 26 and 27 is fixed on the base 29 at a predetermined interval in the rotation axis direction of each of the first roller 24 and the second roller, between the first roller 24 and the second roller. Each of the stoppers 26 and 27 includes a shaft that extends vertically from the base 29 and a roller that rotates about the shaft. The drum 10 is placed on the first roller 24 and the second roller so that the flange 15 is positioned between the roller of the stopper 26 and the roller of the stopper 27. In other words, the drum 10 is configured such that the flange 15 is positioned on the second opening 13 side of the roller of the stopper 26 and the flange 15 is positioned on the second opening 13 side of the roller of the stopper 27. Placed on the first roller 24 and the second roller 25. For this reason, the rotating shaft 39 of the drum 10 is parallel to the rotating shafts of the first roller 24 and the second roller 25, and the distance from the outer wall of the drum 10 is constant.

  In a state where the drum 10 is placed on the first roller 24 and the second roller 25, the stoppers 26 and 27 are located below the outer wall surface of the drum 10, and the rollers of the stoppers 26 and 27 are respectively connected to the flange 15 of the drum 10. It is above the lowest end. For this reason, the movement of the drum 10 in the direction from the first opening 11 toward the second opening 13 is regulated by the flange 15 of the drum 10 coming into contact with the roller of the stopper 26, and the second opening of the drum 10. Movement in the direction from 13 to the first opening 11 is restricted by the flange 15 of the drum 10 coming into contact with the roller of the stopper 27. Therefore, the drum 10 can be rotated while the relative position of the drum 10 with respect to the base 29 in the direction along the rotation axis 39 of the drum 10 is kept constant.

  FIG. 4 is a cross-sectional view of a plane passing through the rotation axis of the drum. Referring to FIG. 4, drum 10 has an inner wall 17. The inner wall 17 is an inclined surface having an inner diameter that increases from the first opening 11 toward the second opening 13. Specifically, the inner wall 17 is a side surface of a truncated cone having the first opening portion 11 as an upper surface and the second opening portion 13 as a bottom surface. The inner wall 17 has a circular cross section perpendicular to the rotation axis 39 at an arbitrary distance from the first opening 11, and the center of the cross section passes through the rotation axis 39. For this reason, when the rotating shaft 39 is horizontal, when the drum 10 rotates around the rotating shaft 39, the height of the inner wall 17 at an arbitrary distance from the first opening 11 is constant. Here, an angle between the inner wall 17 and the horizontal direction is referred to as an inclination angle.

  The drum 10 includes a plurality of first protrusions 31, a plurality of second protrusions 33, and a plurality of third protrusions 35, each protruding inward from the inner wall 17. Each of the plurality of first protrusions 31, the plurality of second protrusions 33, and the plurality of third protrusions 35 protrudes vertically from the inner wall 17 of the drum 10. The direction in which each of the plurality of first protrusions 31, the plurality of second protrusions 33, and the plurality of third protrusions 35 protrudes from the inner wall 17 is not limited to a direction perpendicular to the inner wall 17, for example, You may make it protrude in the direction parallel to gravity.

  In the entangled component separating apparatus 1 in the present embodiment, the drum 10 is driven with the rotary shaft 39 in a horizontal state. When a plurality of parts are inserted from the first opening 11 of the drum 10 and the drum 10 rotates, the plurality of parts receive a force from the first opening 11 toward the second opening 13 in the inner wall 17 by gravity. Since the drum 10 includes a plurality of first protrusions 31, a plurality of second protrusions 33, and a plurality of third protrusions 35, the plurality of parts are included in the inner wall 17, with the plurality of first protrusions 31, It moves from the first opening 11 to the second opening 13 while passing between the plurality of second protrusions 33 and the plurality of third protrusions 35.

  The plurality of first protrusions 31 are arranged at predetermined intervals in the circumferential direction at a distance L1 from the first opening 11. It is preferable that the maximum length of the interval between the two adjacent first protrusions 31 is 2.5 to 3 times the maximum length of the part. For this reason, the number of the 1st projection parts 31 is decided by the diameter of a drum, and the maximum length of parts. Each of the plurality of first protrusions 31 is shorter than the radius of the inner wall 17 at a distance L1 from the first opening 11 of the drum 10. For this reason, since each of the plurality of first protrusions 31 does not come into contact with the other first protrusions 31, the probability that one part is simultaneously entangled with two or more of the plurality of first protrusions 31 is reduced. can do.

  In addition, the distance between the ends of the plurality of first protrusions 31 is set so that the parts do not get entangled with two or more of the plurality of first protrusions 31 as the drum 10 rotates. Specifically, it is preferable that the minimum value of the interval between the end portions of the plurality of first protrusions 31 is larger than the maximum length of the part. For this reason, the maximum value of the length of each of the plurality of first protrusions 31 is determined by the interval between the end portions of each of the plurality of first protrusions 31 and the maximum length of the parts. If one part is simultaneously entangled with two of the plurality of first protrusions 31, even if the drum 10 rotates, the movement of the parts is restricted by the two first protrusions 31, and the part cannot be moved. There is a case. For this reason, the minimum value of the distance between the end portions of each of the plurality of first protrusions 31 is made larger than the maximum length of the parts, so that it does not get entangled with other parts among the plurality of parts thrown into the first opening. It is possible to prevent a single part from being simultaneously entangled with two or more of the plurality of first protrusions 31.

  In addition, when a plurality of parts are put into the drum 10 from the first opening 11, a part group consisting of a plurality of parts entangled with other parts is a plurality of first protrusions as the drum 10 rotates. The distances between the ends of the plurality of first protrusions are set so that two or more of the portions 31 are simultaneously entangled. A part group may be simultaneously entangled with two or more of the plurality of first protrusions 31. When the number of the first protrusions 31 entangled among the plurality of first protrusions 31 in the parts group increases, the number of movements of the parts group during rotation of the drum 10 is the same as the number of the first protrusions 31 entangled. Regulated in the direction of However, two or more parts intertwined with any of the plurality of first protrusions 31 among the plurality of parts included in the part group are all different. For this reason, the part group receives the force from a number of directions because the direction of receiving gravity changes as the drum 10 rotates, and the shape of the part group changes. In other words, the way of entanglement between a plurality of parts constituting the part group changes. Specifically, in the part group, as the drum 10 rotates, the part that has been entangled with the part that has been entangled until then is disengaged from the part group, and the part that has not been entangled until then. There are parts, parts for which the entanglement with the first protrusion 31 that has been entangled so far is eliminated, parts that are newly entangled with the first protrusion 31, and the like. For this reason, as for the parts group, as the drum 10 rotates, the entanglement with the first protrusions entangled among the plurality of first protrusions 31 may be eliminated, and the plurality of first protrusions may be eliminated. In some cases, the first protrusions 31 that are not entangled with each other may be entangled.

  For this reason, the part group changes its shape while being entangled with two or more of the plurality of first protrusions 31 as the drum 10 rotates, so that a part that detaches from the part group is generated. Of the parts that detach from the parts group, a single part that is not entangled with a small number of parts group and other parts passes through the eight first protrusions 31 and is more open than the eight first protrusions 31. It is possible to move to the side.

  The plurality of second protrusions 33 include one or more sets arranged at a predetermined interval in the circumferential direction on the second opening 13 side than the plurality of first protrusions 31. The interval at which two adjacent second protrusions 33 belonging to the same group are arranged is determined by the size of the parts. It is preferable that the maximum length of the interval between the two adjacent second protrusions 33 is 1.5 to 2 times the maximum length of the part. For this reason, the number of the 1st projection parts 31 is decided by the diameter of a drum, and the maximum length of parts. Further, the lengths of the plurality of second protrusions 33 are shorter than the lengths of the plurality of first protrusions 31. The length of the plurality of second protrusions 33 is preferably less than or equal to half the length of the plurality of first protrusions 31. Further, the lengths of the plurality of second protrusions 33 do not have to be the same, and the lengths may be different.

  The plurality of third protrusions 35 include one or more sets arranged at a predetermined interval in the circumferential direction on the first opening 11 side than the plurality of first protrusions 31. The interval at which two adjacent third protrusions 35 belonging to the same group are arranged is determined by the size of the part. It is preferable that the maximum length of the interval between the two adjacent third protrusions 35 is 2.5 to 3 times the maximum length of the part. For this reason, the number of the 3rd projection parts 35 is decided by the diameter of a drum, and the maximum length of parts. The lengths of the plurality of third protrusions 35 are shorter than the lengths of the plurality of first protrusions 31. The length of the plurality of third protrusions 35 is preferably less than or equal to half the length of the plurality of first protrusions 31. Further, the lengths of the plurality of third protrusions 35 do not have to be the same, and the lengths may be different.

  Here, the drum 10 has three first sets including eight first protrusions 31, sixteen second protrusions 33, and eight third protrusions 35 as one set. An example of having three sets will be described. The 1st projection part 31, the 2nd projection part 33, and the 3rd projection part 35 are bar-shaped shapes with a circular cross section. The end portions of the first projecting portion 31, the second projecting portion 33, and the third projecting portion 35 are rounded. This is to prevent the parts from being damaged by contact with the parts and to make the entangled parts easy to separate. Further, each of the first protrusion 31, the second protrusion 33, and the third protrusion 35 has a surface polished when made of metal to make the entangled parts slip easily, and made of resin. Is preferably coded with a fluororesin.

  FIG. 5 is a development view of the drum inner wall. Referring to FIG. 5, eight first protrusions 31 are arranged at equal intervals in the circumferential direction at a distance L1 from first opening 11. In addition, sixteen second protrusions 33 constituting the first set are arranged at equal intervals in the circumferential direction at a distance L2 from the first opening 11, and at a distance L3 from the first opening 11. Sixteen second protrusions 33 constituting the second set are arranged at equal intervals in the circumferential direction, and sixteen constituting the third set in the circumferential direction at a distance L4 from the first opening 11. The second protrusions 33 are arranged at equal intervals. Since the 16 second protrusions 33 in the first to third groups are the same, here, the 16 second protrusions 33 included in the first set will be described.

  Further, eight third protrusions 35 constituting the first set are arranged at equal intervals in the circumferential direction at a distance L7 from the first opening 11, and at a distance L6 from the first opening 11. Sixteen third protrusions 35 constituting the second set are arranged at equal intervals in the circumferential direction, and eight pieces constituting the third set are arranged in the circumferential direction at a distance L5 from the first opening 11. The third protrusions 35 are arranged at equal intervals. Since the eight third projecting portions 35 of each of the first to third sets are the same, the eight third projecting portions 35 included in the first set will be described here.

  6 is a cross-sectional view taken along line BB in FIG. With reference to FIGS. 5 and 6, the eight first protrusions 31 protrude from the inner wall 17 toward the rotation shaft 39. Since the eight first protrusions 31 are arranged at equal intervals, the interval between the two adjacent first protrusions 31 is set to three times the maximum length of the part.

  7 is a cross-sectional view taken along line BB in FIG. With reference to FIGS. 5 and 7, the 16 second protrusions 33 in the third set protrude from the inner wall 17 in the direction of the rotation axis 39. Since the 16 second protrusions 33 are arranged at equal intervals, the interval between the two adjacent second protrusions 33 is 1.5 times the maximum length of the part.

  The distance L2 is longer than the distance L1. The difference G1 obtained by subtracting the distance L2 from the distance L3 from which the second set of 16 second protrusions 33 protrudes indicates the distance between the first set and the second set, and the first opening of the inner wall 17 of the drum 10 11 and a diameter D1 at a distance L2, and an inclination angle θ of the inner wall 17 are determined. For example, the difference G1 is preferably greater than or equal to D1 tan θ. The distance L3 is longer than the distance L2, and the difference G2 obtained by subtracting the distance L3 from the distance L4 indicates the distance between the second set and the third set, and the diameter at the distance L3 from the first opening 11 of the inner wall 17 of the drum 10. It is determined by D2 and the inclination angle θ of the inner wall 17. For example, the difference G2 is preferably greater than or equal to D2 tan θ.

  The distance L5 is shorter than the distance L1, the distance L6 is shorter than the distance L5, and the distance L7 is shorter than the distance L6. A value obtained by subtracting the distance L7 from the distance L6 indicates an interval between the first set and the second set, and a value obtained by subtracting the distance L6 from the distance L5 indicates an interval between the second set and the third set. The interval between the first set and the second set, and the interval between the second set and the third set are preferably larger than the maximum length of the parts. More preferably, the interval between the first set and the second set, and the interval between the second set and the third set are preferably larger than the interval between the first set and the second set of the second protrusion 33. .

  8 is a cross-sectional view taken along the line CC of FIG. With reference to FIGS. 5 and 8, the first set of eight third protrusions 35 protrude from the side wall of the drum 10 in the direction of the rotation shaft 39. Since the eight third protrusions 35 are arranged at equal intervals, the interval at which the two third protrusions 35 adjacent to each other are arranged is three times the maximum length of the part.

  FIG. 9 is a plan view showing an example of parts put into the entangled component separating apparatus according to the present embodiment. Referring to FIG. 9, the part has a circular shape with a circular cross section and a part opened. Since some parts are open, it is easy to get entangled from other parts.

  Next, in the entangled component separating apparatus 1 according to the present embodiment, the state of the plurality of parts when a plurality of parts are introduced into the drum 10 from the first opening 11 and the motor 21 is driven will be described. Here, the motor 21 rotates in the same direction at a constant angular velocity. The plurality of parts introduced into the drum 10 from the first opening 11 have the lowest opening of the first opening 11 of the drum 10 higher than the lowest end of the second opening 13, so that the first opening 11 is caused by gravity. The force in the direction toward the second opening 13 is received. For this reason, it is preferable that the inner wall 17 of the drum 10 is polished so that parts are slippery.

  At the stage where a plurality of parts are introduced into the drum 10 from the first opening 11 and the motor 21 is driven, a multipart group in which four or more parts of the plurality of parts are entangled with each other includes eight first protrusions 31. Any of the above restricts movement of the eight first protrusions 31 toward the second opening 13. Further, a minority part group in which three or less parts are entangled among a plurality of parts passes through the eight first protrusions 31 and is closer to the second opening 13 than the eight first protrusions 31. It is possible to move. A single part that is not intertwined with other parts among the plurality of parts passes through the eight first protrusions 31 and moves to the second opening 13 side rather than the eight first protrusions 31. It is possible.

  In the present embodiment, the minimum value of the distance between the end portions of each of the eight first protrusions 31 is larger than the maximum length of the part. For this reason, one part is not entangled with two or more of the eight first protrusions 31 at the same time, and a single part that does not entangle with other parts does not entangle with any of the eight first protrusions 31. Moreover, the probability of moving to the second opening 13 side can be increased. In the present embodiment, the minimum value of the distance between the end portions of the eight first protrusions 31 is set to a value larger than the maximum value of the part size.

  In addition, a large number of parts groups may be simultaneously entangled with two or more of the eight first protrusions 31. In the present embodiment, the minimum value of the distance between the end portions of the eight first protrusions 31 is set to be twice or less the maximum size of the part. This is to prevent a part group composed of two or more parts from passing between the ends of the eight first protrusions 31. Note that the minimum value of the distances between the end portions of the eight first protrusions 31 may be set to a value larger than twice the maximum size of the parts. In this case, the number of parts constituting a part group that allows passage between the end portions of the eight first protrusions 31 increases. When the number of the first protrusions 31 intertwined among the eight first protrusions 31 increases, the movement of the parts group during the rotation of the drum 10 is the number of the first protrusions 31 intertwined. Regulated in the same number of directions. However, two or more parts intertwined with any of the eight first protrusions 31 among the plurality of parts included in the multiple parts group are all different. For this reason, in the multi-part group, as the drum 10 rotates, the entanglement method of the plurality of parts constituting the multi-part group changes, and the shape of the multi-part group changes. Specifically, among the many parts group, as the drum 10 rotates, the part that has been entangled with the part that has been entangled until then is removed, and the part that has left the part part group has not been entangled until then. There are parts that are entangled with the parts, parts that are entangled with the first protrusion 31 that have been entangled so far, parts that are entangled with the first protrusion 31 and the like. For this reason, in the multiple parts group, as the drum 10 rotates, the entanglement with the first protrusions entangled among the eight first protrusions 31 may be eliminated, and the eight first In some cases, the first protrusion 31 may be entangled with the first protrusion that was not entangled.

  For this reason, the multi-part group changes its shape while being entangled with two or more of the eight first protrusions 31 as the drum 10 rotates, so that a part that detaches from the multi-part group is generated. A single part that is not entangled with a small number of parts and other parts out of parts that detach from the large number of parts passes through between the eight first protrusions 31 and is a second opening than the eight first protrusions 31. Movement to the 13 side is possible.

  The multiple parts group entangled with any of the eight first protrusions 31 may be entangled with at least one of the eight third protrusions 35 belonging to each of the first to third groups. The eight third protrusions 35 belonging to each of the first to third groups rotate the whole of a large number of parts entangled with any of the eight first protrusions 31 as the drum 10 rotates. . As a result, a single part or a small number of parts separated from the large number of parts group is between the eight third protrusions 35 and the eight first protrusions 31 belonging to the first to third groups. It is possible to pass through the first opening 31 and move toward the second opening 13 rather than the eight first protrusions 31.

  When the drum 10 does not have the eight third protrusions 35 belonging to the first to third sets, the multiple parts group entangled with any of the eight first protrusions 31 is the eight first protrusions. A portion entangled with one of the protrusions 31 receives a force from the first protrusion 31, but a portion that is not entangled with any of the eight first protrusions 31 receives a force from the part with which it entangles and rotates. . For this reason, the force which the part entangled in any of the eight 1st projection parts 31 receives from the 1st projection part 31 is transmitted to another part in order, and the whole many parts group rotates. At this time, the entanglement between a plurality of parts entangled with each other may become strong.

  When the drum 10 has eight third protrusions 35 belonging to each of the first to third sets, the entire multiple parts group entangled with any of the eight first protrusions 31 is Since it is rotated with rotation, it prevents the entanglement force between multiple parts that make up the multiple parts group from becoming strong, and makes it easy to separate multiple parts that make up the multiple parts group from the multiple parts group Can do.

  Of the plurality of parts put into the first opening 11, a part that passes between the eight first protrusions 31 and reaches a position equal to or longer than the distance L <b> 2 from the first opening 11 is a single part. Or a few parts group. Since the drum 10 is inclined, the single part moves through the gap between the 16 second protrusions 33 of each of the first to third sets, and moves to the second opening 13 by gravity to be discharged from the drum 10. Is done. The minority part group is restricted from moving to the second opening 13 by any one of the 16 second protrusions 33 constituting the first set. The minority part group is entangled with one of the 16 second projecting portions 33 constituting the first set, and is lifted upward by the rotation of the drum 10 while being entangled with the second projecting portion 33. When the entanglement with the two projecting portions 33 is eliminated, it falls downward. Since the minority parts group collides with the inner wall of the drum 10 when dropped, the entanglement may be eliminated by the external force. Of the two or more parts constituting the small number of parts group, a single part in which the entanglement is eliminated can move to the second opening 13 by gravity.

  On the other hand, since the difference G1 obtained by subtracting the distance L3 from the distance L4 is greater than or equal to D1 tan θ, the position where the minority part group falls is entangled with one of the 16 second protrusions 33 constituting the second set. For this reason, a new minority part group that constitutes a plurality of parts that have not been entangled with other parts in the minority part group is one of the 16 second protrusions 33 that constitute the second set. The entanglement is lifted upward by the rotation of the drum 10 and then falls downward when the entanglement with the second protrusion 33 is eliminated by gravity. A single part in which the entanglement is eliminated among two or more parts constituting the minority part group can move to the second opening 13 by gravity, but the entanglement with other parts in the minority part group Since the difference G2 obtained by subtracting the distance L3 from the distance L4 is greater than or equal to D2 tan θ, the new minority part group that constitutes the plurality of parts for which is not solved is any one of the 16 second protrusions 33 that constitute the third set Entangled and lifted upward by the rotation of the drum 10, and then falls downward when the entanglement with the second protrusion 33 is eliminated by gravity. Thus, since the minority part group is dropped three times, the minority part group can be separated into a single part with high probability. In addition, although the example provided with 3 sets of 16 2nd projection parts 33 was demonstrated here, you may make it change the number of sets according to the shape, material, etc. of parts. By increasing the number of sets, it is possible to increase the probability that it can be separated into single parts. Moreover, when the probability that it can be separated into individual parts becomes a predetermined value, one set may be used.

  In the present embodiment, the rotating shaft 39 of the drum 10 is in the horizontal direction, but the drum 10 may be tilted and rotated so that the rotating shaft 39 intersects the horizontal direction. FIG. 10 is a left side view of the entangled component separating device with the drum tilted. Referring to FIG. 10, drive mechanism 20 supports drum 10 such that the angle of rotating shaft 39 with respect to the direction of gravity can be adjusted. Here, the angle of the rotation shaft 39 with respect to the horizontal direction perpendicular to the direction of gravity is referred to as a support angle, and FIG. 10 shows an example in which the support angle R (R> 0). The support angle R is such that the inclination angle of the inner wall 17 where the lowermost end of the first opening 11 is higher than the lowermost end of the second opening 13 is greater than 0, and the inclination angle of the inner wall 17 is greater than the vertical. It is a range that becomes smaller.

  When the drum 10 is tilted and rotated so that the rotation shaft 39 intersects the horizontal direction, the part only needs to be able to move the inner wall 17 in the direction from the first opening 11 toward the second opening 13. In other words, the inner wall 17 forms an inclined surface in which the potential energy of the parts decreases in the direction from the first opening 11 toward the second opening 13. For example, the inner wall 17 has an inclined surface with a smaller inner diameter in the direction from the first opening 11 toward the second opening 13 or the same inner diameter in the direction from the first opening 11 toward the second opening 13. You may make it have an inclined surface.

<Ninth Modification>
The entangled component separating apparatus 1 in the above-described embodiment has been described by taking as an example the case where the rotation shaft 39 of the drum 10 has a constant distance from the inner wall 17 of the drum 10.

  The rotating shaft 39 of the drum 10 may be positioned outside the inner wall 17 of the drum 10 in parallel with the central axis of the inner wall 17 of the drum 10.

  As described above, the entangled component separating apparatus 1 according to the present embodiment includes a cylindrical drum 10 including the first opening 11 serving as a part introduction port and the second opening 13 serving as a part discharge port. A plurality of first protrusions 31 and second protrusions 35 projecting from the inner wall 17 of the drum 10 to the inside of the drum 10, and the lowermost end of the first opening 11 is higher than the lowermost end of the second opening 13. And a drive mechanism 20 that rotates the drum about a rotation shaft 39 that intersects the direction of gravity. The inner wall 17 of the drum 10 has a large inner diameter in the direction from the first opening 11 to the second opening 13. It is an inclined surface.

  For this reason, the inner wall 17 has a larger inner diameter in the direction from the first opening 11 toward the second opening 13, and the lowermost end of the first opening 11 is higher than the lowermost end of the second opening 13. Since the drum 10 is rotated around the rotation shaft 39 that intersects the direction of gravity, the parts introduced into the first opening 11 move toward the second opening 13. On the other hand, a part group composed of a plurality of parts intertwined with other parts among the parts introduced into the first opening 11 is entangled with one of the plurality of first protrusions 31, so that the part group is the second opening. 13 can be prevented from moving. A part group entangled with any of the plurality of first protrusions 31 is lifted upward by the rotation of the drum 10 and then falls by gravity. For this reason, entanglement with other parts may be canceled among the plurality of parts included in the part group due to falling. Therefore, parts entangled with each other can be easily separated.

  Further, the distance between the ends of the eight protrusions 31 is set so that the parts do not get entangled with two or more of the first protrusions 31 simultaneously with the rotation of the drum 10. Specifically, the minimum value of the distance between the end portions of the eight first protrusions 31 is set to a value larger than the maximum value of the part size. For this reason, it is possible to prevent the parts from moving with the rotation of the drum 10.

  In addition, when a plurality of parts are put into the drum 10 from the first opening, a group of parts that are tangled with other parts among the plurality of parts has eight protrusions as the drum 10 rotates. The distance between the ends of the plurality of protrusions is set so as to be entangled with two or more simultaneously. Specifically, the minimum value of the distance between the end portions of the eight first protrusions 31 is set to be twice or less the maximum size of the part. As a result, a part group composed of two or more parts is simultaneously entangled with two or more of the eight first protrusions 31 as the drum 10 rotates, so that the part group does not move to the second opening 13. can do. Further, since the parts group receiving the force in the direction of gravity receives the force from multiple directions as the drum rotates, each of the plurality of parts in the part group can be separated from the parts group.

  The inner wall 17 includes eight first protrusions 31 that are spaced apart from each other in the circumferential direction at a distance L1 from the first opening 11, and the second opening 13 from the eight first protrusions. And a plurality of second protrusions 33 arranged at intervals on the side in the circumferential direction. For this reason, a part group consisting of a plurality of parts intertwined with other parts among the parts that have passed between the eight first protrusions 31 is entangled with one of the plurality of second protrusions 33. Can be prevented from moving to the second opening 13. Further, a part group entangled with any of the plurality of second protrusions 33 is lifted upward by the rotation of the drum 10 and then falls by gravity. For this reason, entanglement with other parts may be canceled among the plurality of parts included in the part group due to falling. Therefore, parts entangled with each other can be easily separated. As a result, the number of parts entangled in stages can be reduced, so that the entangled parts can be separated efficiently.

  The inner wall 17 includes first portions 18A and 18B extending from the first opening 11 to a position where the eight first protrusions 31 are disposed, and eight first firsts from the second opening 13. 2nd part 19A, 19B extended to the position where the projection part 31 is arrange | positioned. For this reason, the force toward the second opening 13 received by the parts whose movement to the second opening 13 is restricted by the eight first protrusions 31 and the parts that have passed through the eight first protrusions 31 are received. The force toward the second opening 13 can be adjusted.

  The embodiment disclosed this time should be considered as illustrative in all points and not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.
