  According to the sorting conveyor of Patent Document 1, when transporting a conveyed product in a branching direction, the electromagnet disposed on the upstream side is energized to attract the guide body, and then along the magnet disposed on the downstream side. The guide body is moved to branch to the branch rail.

  However, according to the sorting conveyor of Patent Document 1, the guide body collides with the sharp boundary wall that separates the main rail and the branch rail from the front due to a shift in the conveyance speed and the energization timing to the electromagnet. There was a problem that damage and deformation occurred.

  When the guide body is damaged or deformed, the guide body stops moving in the guide rail, and the guide body that continuously moves stops clogging in the guide rail. There was a problem that the machine was damaged or the conveyed product on the movement guide surface was pushed out of the conveyor by the conveyed product. In addition, there is a problem that sorting failure occurs due to breakage or deformation of the guide rail.

  This invention makes it an example of a subject to cope with such a problem. That is, the guide body can be surely branched, thereby preventing the guide body from being clogged in the guide rail, ensuring that the transported goods are sorted and transported, and damaging or deforming the guide body or the guide rail.

  The drive rotator 1 and the driven rotator 2 can use a sprocket or a pulley, and the rotation band 3 can use a chain wound around the sprocket or a belt wound around the pulley. The drive rotator 1 is driven to rotate when the driving torque of the drive mechanism 10 is transmitted, so that the rotation band 3 can be rotated endlessly and the driven rotator 2 can be driven to rotate by this drive rotation. It has become.

  The support 4 can be a shaft or a pipe. Such a support body 4 is provided with a space S between the support bodies 4 adjacent to each other in the transport direction and arranged in parallel, and the left and right ends of the support body 4 are fixed to the rotation band 3, respectively. A movement guide surface B1 that moves in the transport direction with endless rotation is configured.

  The sorting means D is formed in a shaft shape using a plurality of sorting bodies 5 arranged along the transport direction and a material attracted by magnetic force, and is provided so as to be integrated with the sorting body 5, and the movement guide surface B <b> 1. A main body 6a that is positioned below the movement guide surface B1, engages with the guide body 5a, and is laid in a direction parallel to the conveying direction, and a main rail A guide rail 6 having branch rails 6b and 6c laid so as to branch from 6a in a direction inclined with respect to the conveyance direction, and arranged upstream of a branch position P between the main rail 6a and the branch rails 6b and 6c. The distribution rail 7 and the magnets 8a and 8b respectively disposed on the left and right side walls 70 and 71 of the distribution rail 7 and the upstream side of the distribution rail 7 are rotated alternately around the vertical axis. In Is supported, by rotating the right and left alternately, and a sorting member 9 to distribute to guide the guide member 5a to the left side wall 70 direction and the right side wall 71 direction.

  The sorting body 5 is fixed to the lower surface of the sorting plate 5b placed on the movement guide surface B1 so as to be bridged over both the support bodies 4 adjacent to each other in the transport direction, and is adjacent in the transport direction. The guide body 5c is slidably engaged with both the supporting bodies 4 in the left-right direction, and the guide body 5a is fixed to the lower surface of the guide body 5c.

  The sorting body 5 is disposed at the right end of the movement guide surface B1 in the drawing as a fixed position. When the transported object C is placed and guided to the left side, the sorting body 5 slides leftward from the fixed position. Has been.

  The guide body 5a is configured as an adsorbing portion made of a material that is adsorbed by a magnetic force as a whole, has a length that engages with the guide rail 6, and is engaged so as to be moved and guided along the guide rail 6. . The material adsorbed by the magnetic force constituting the guide body 5a is preferably a high strength material such as iron or alloy which is a magnetic material.

  The sorting plate 5b is used to place the conveyed product C, and the edges of the sorting plates 5b adjacent to each other in the carrying direction are in contact with each other, or are arranged in parallel with a slight gap therebetween. The conveyed product C to be placed can be moved in the left direction by sliding the sorting plate 5b in the left direction.

  The slide portion 50c is a plate-shaped member having a thickness such that slight play is generated with respect to the space S. The engaging portion 51c is formed in a concave shape so as to be able to engage with the support 4 so as to be sandwiched from above and below.

  According to such a sorter 5, the guide 5a is guided to the branch rails 6b and 6c in the guide rail 6 and slides to the left by the movement of the moving guide surface B1 in the transport direction accompanying the endless rotation of the rotary band 3. As the guide body 5a slides, the guide body 5c slides, and as the guide body 5c slides, the sorting plate 5b slides to move the conveyed product C on the sorting plate 5b to the left. While sliding, it can be conveyed in the downstream direction.

  The guide rail 6 is arranged at a position along the main rail 6a parallel to the transport direction and along the fixed position of the sorting body 5, and the branch rails 6b and 6c are branched from the main rail 6a to the left in an inclined manner. Has been placed.

  The distribution rail 7 has a rail width that is at least twice the diameter of the guide body 5a. The right half of the rail width is continuous with the main rail 6a, and the left half is continuous with the branch rails 6b and 6c. Are arranged to be.

  Further, the sorting rail 7 is guided when the guide body 5a is moved in the conveying direction in a state where the guide body 5a is in contact with the right side wall 71 of the sorting rail 7 and in a state where the guide body 5a is in contact with the left side wall 70 of the sorting rail 7. The body 5a is disposed at a position where it does not come into contact with the branch position P. Specifically, the center line L of the sorting rail 7 passes through the branch position P. (Old, 0030 moved to 0031)

  The magnets 8a and 8b both have the same magnetic force, and are fixed to both side walls 70 and 71 of the sorting rail 7, respectively. The magnets 8a and 8b can attract the guide body 5a moving along the transport direction to either one of the side walls 70 and 71, and have enough magnetic force to move along the transport direction while the guide body 5a is attracted. Is.

  The distribution body 9 is provided with a guide rail 9 a for guiding the guide body 5 a to the distribution rail 7. The downstream end of the guide rail 9 a is connected to the upstream end of the distribution rail 7. The guide body 5a is pivotally supported so as to rotate within a range in which the guide body 5a can be moved to the sorting rail 7 so as not to collide.

  The distribution body 9 is connected to an air cylinder 7a on the right side thereof, and is rotated by expansion and contraction of the air cylinder 7a. The drive source for rotating the sorting body 9 is not limited to the air cylinder 7a, but may be a rotary actuator, a motor, or the like.

  Moreover, before the operation | movement, the distribution body 9 is arrange | positioned so that the center line L1 of the guide rail 9a may be on the same line as the center line L of the distribution rail 7, and by rotating from this position, a guide body 5a can be distributed and moved in the direction of the left side wall 70 and the direction of the right side wall 71 of the distribution rail 7.

  The sorting body 9 is set by switching the rotation direction when the number of transported articles C to be sorted reaches the set number, and moving the guide body 5a to the target main rail 6a and the branch rails 6b and 6c. It is preferable to control so that the number of conveyed articles C is sorted in the left-right direction.

  Under the guide rail 6, a return rail 60 including a first return rail 60a and a second return rail 60b for returning the guide body 5a to the upstream side of the guide rail 9a of the distribution body 9 is disposed.

  The first return rail 60a is disposed directly below the main rail 6a and in parallel with the transport direction of the transport unit B, and contacts the guide body 5a that is reversed downstream of the transport unit B so that the distribution body 9 It is formed so as to reach the upstream side of the guide rail 9a.

  The second return rail 60b is disposed obliquely from the leftmost downstream side of the transport unit B to the most upstream side of the first return rail 60a, and contacts the guide body 5a that is reversed on the downstream side of the transport unit B. The distribution body 9 is formed so as to reach the upstream side of the guide rail 9a.

  As another configuration of the return rail 60, as shown in FIG. 7, the first return rail 60a for returning the guide body 5a to the upstream side of the guide rail 9a of the distribution body 9 is returned to the main rail 6a and the branch rails 6b and 6c. The structure which connects the 2nd return rail 60b and the 3rd return rail 60c continuously is mentioned.

  The first return rail 60a inverts the main rail 6a on the downstream side of the transport unit B, passes directly below the main rail 6a, and is inverted on the upstream side of the transport unit B to reverse the guide rail 9a of the sorting body 9. It is formed to reach upstream.

  The second return rail 60b and the third return rail 60c invert the branch rails 6b and 6c on the downstream side of the conveyance unit B, and are connected to the first return rail 60a from the middle of the first return rail 60a. The guide body 5a that moves along the second return rail 60b and the third return rail 60c is formed to move to the first return rail 60a.

  According to the sorting conveyor A configured as described above, when the conveyed product C is transported at a fixed position, the guiding body 5a is rotated in the right direction by moving the sorting body 9 in the right direction toward the right rail 71. Can be moved toward.

  Further, the guide body 5a moved toward the right side wall 71 can be attracted to the right side wall 71 by the magnetic force of the magnet 8a disposed on the right side wall 71, and in the conveying direction while being attracted to the right side wall 71. Can be moved to.

  And when this guide body 5a moves to the main rail 6a from the distribution rail 7, it can be moved to the main rail 6a without contacting the branch position P by the arrangement configuration of the distribution rail 7 mentioned above.

  On the other hand, when the conveyed product C is conveyed in the left direction, the guide body 5a can be moved toward the left side wall 70 with respect to the distribution rail 7 by rotating the distribution body 9 in the left direction.

  Further, the guide body 5a moved toward the left side wall 70 can be attracted to the left side wall 70 by the magnetic force of the magnet 8a disposed on the left side wall 70, and in the transporting direction while being attracted to the left side wall 70. Can be moved to.

  When the guide body 5a moves from the distribution rail 7 to the branch rails 6b and 6c, the guide body 5a can be moved to the branch rails 6b and 6c without being brought into contact with the branch position P by the arrangement configuration of the distribution rail 7 described above. .

  Therefore, the sorting conveyor A can move the guide body 5a that is distributed and moved to the main rail 6a and the branch rails 6b and 6c without contacting the branch position P when sorting the conveyed product C. The guide body 5a can be reliably moved to the main rail 6a and the branch rails 6b and 6c, thereby clogging the guide body 5a in the guide rail 6 and damaging the guide body 5a and the branch position P. Further, since it is possible to prevent deformation and conveyance failure due to these, it is possible to reliably carry out sorting and conveyance of the conveyed product C.

  Further, the guide body 5a can be moved by the first return rail 60a, the second return rail 60b, and the third return rail 60c so that the sorting plate 5b returns to the fixed position. The circulating sorting plate 5b can always be returned to the fixed position on the movement guide surface B1, and the sorting and conveying of the conveyed product C can be started from this fixed position.

  The guide body 5a and the sorting rail 7 may be configured as shown in FIG. 8 in addition to the above-described configuration. The guide body 5a includes a roller 50a that is rotatably supported around a shaft of the guide body 5a in a part above the guide body 5a.

  The roller 50a is an attracting portion made of a material that is attracted by the magnetic force of the magnets 8a and 8b. Here, the guide body 5a may use a material other than the material attracted by the magnetic force of the magnets 8a and 8b.

  The sorting rail 7 is provided with magnets 8a and 8b at the upper ends of both side walls 70 and 71, the roller 50a is positioned between the magnets 8a and 8b, and the guide body 5a is positioned between the side walls 70 and 71. Is formed.

  The gap between the magnets 8a and 8b is larger than the diameter of the roller 50a, and the guide body 5a does not protrude from the center line L of the sorting rail 7 when the roller 50a is attracted to one or the other of the magnets 8a and 8b. The spacing is such that it can be held in position.

  According to the guide body 5a and the sorting rail 7 as described above, the guide body 5a can be brought close to one or the other of the side walls 70 and 71 along with the adsorption of the roller 50a to one or the other of the magnets 8a and 8b. Accordingly, the guide body 5a can be moved to the main rail 6a and the branch rails 6b and 6c without contacting the branch position P.

  Further, the rolling resistance of the roller 50a with respect to the magnets 8a and 8b can reduce the contact resistance due to the attracting force of the magnets 8a and 8b, so that the guide body 5a can be moved smoothly in the sorting rail 7.

  In the above-described embodiment, the guide rail 6 is obtained by branching the two branch rails 6b and 6c with respect to the single main rail 6a, and the example is shown as the sorting conveyor A including the two sorting means D. The number of branch rails 6b and 6c branched from the main rail 6a may be one or more than three, and the sorting means D is the same as the number of branch rails 6b and 6c.

  In the above-described embodiment, the shaft-shaped guide body 5a is exemplified. However, the guide body 5a may include a roller that rotates around the axis of the guide body 5a.

  Further, the branch direction of the guide rail 6, the arrangement position and shape of the guide rail 6 and the return rail 60, the shape and size of the sorting plate, etc. are arbitrary depending on the transport distance of the transport unit B, the shape and size of the transported object C, etc. Can be set.

  Further, the magnets 8a and 8b may be of any length over the entire area of the sorting rail 7 or a plurality of the magnets 8a and 8b arranged over the entire area of the sorting rail 7. Any shape can be used as long as it can be applied.
