The extruded body 5 is positioned by the contact and contact between the guide portion 43 and the sandwiched portion 31. Furthermore, when the extruded body 5 as a shoe slides in the left-right direction, the extruded body 5 comes into contact with the guide plate portion 55, thereby preventing the extruded body 5 from tilting (rattle).

  In FIG. 5C, contact engagement between the rotation restricting end portion 47 of the mounting plate portion 42 of the slat 2 and the receiving portion of the sandwiched portion 31 of the extruded body 5, and the arc-shaped portion 46a and the extruded portion 33 And the contact between the guide portion 43 and the sandwiched portion 31 restrict the rotation of the extruded body 5 with respect to the slat 2.

  The main body portion 41 which is a base portion includes a plurality of parallel cylindrical portions 40 having an axial direction in a direction intersecting the transport direction A, for example, two cylindrical end-opening cylindrical portions 40, and these two cylindrical portions. 40 and the curved plate-like connecting portion 51, and the upper end portion of each cylindrical portion 40 is erected on the lower surface of the arcuate portion 46a of the mounting plate body portion 46 of the mounting plate portion 42. And a flat plate-like portion 52 connected to each other.

  The cylindrical portion 40 is formed in a perfect circle shape centered on a horizontal central axis (axial center) X, and is located from one longitudinal end of the slat 2 to the other longitudinal end. The cylindrical portion 22 of the bush 21 is inserted and fitted on the inner peripheral side of each end portion in the axial direction of the cylindrical portion 40, and the flange portion 23 comes into contact with the end surface of the cylindrical portion 40. The bush 21 is positioned with respect to the cylindrical portion 40 by the contact. Further, the support shaft portion 14 of the chain 11 is rotatably fitted and inserted into the positioned fitting hole portion 24 of the bush 21. Thus, each of the plurality of slats 2 is connected to the chain 11 via only a plurality of, for example, four bushes 21. That is, the slat 2 is constructed between both the chains 11 only through the bush 21.

  The connecting portion 51 has two arc-shaped portions 51a having a quarter-circular cross section (including a substantially quarter-circular shape), and these arc-shaped portions 51a are formed into a flat plate-like flat portion 51b. Are connected. The flat plate-like portion 51b is positioned above a horizontal line L connecting the two central axes X, and the arc-shaped portion 51a is inclined obliquely upward from each end in the short direction of the flat plate-like portion 51b. The upper end of each arcuate portion 51a is connected to the upper portion of the tubular portion 40.

  The plurality of guide plate portions 55 of each guide portion 43 guide the sliding and rotation of the extruded body 5 with respect to the slat 2. That is, when the extruded body 5 slides with respect to the slat 2, the extruded body 5 is guided by the guide portion 43 and the arcuate portion 46 a of the mounting plate portion 42, and is directed relative to the slat 2 in a direction perpendicular to the transport direction A. Slide left and right. Further, when the extruded body 5 rotates with respect to the slat 2, the extruded body 5 rotates and slides with respect to the slat 2 about the central axis X of the cylindrical portion 40 while being guided by the guide portion 43.

  In addition, each guide portion 43 is a plurality of circular arc sections that are positioned side by side on a virtual circle centered on the central axis X of the cylindrical portion 40 of the main body portion 41 and guide the extruded body 5, for example, It has two guide plate portions 55, and the center portion in the arc direction (the center portion in the width direction) of each guide plate portion 55 is cylindrical via a flat plate-like connecting portion 56 along the radial direction of the cylindrical portion 40. It is connected to the outer peripheral surface of the portion 40.

  That is, one guide plate portion 55 of the two guide plate portions 55 is provided at the distal end portion of the connecting portion 56 protruding from the lower end portion of the cylindrical portion 40 and is positioned below the cylindrical portion 40. . The other guide plate portion 55 of the two guide plate portions 55 is provided at the distal end portion of the connecting portion 56 protruding from the outer end portion of the tubular portion 40 and is located on the outer side of the tubular portion 40. ing. Both guide plate portions 55 are in sliding contact with the arcuate surface 32 of the sandwiched portion 31 of the extruded body 5 in a planar shape. Note that the arc center angle of the arc-shaped guide plate portion 55 is smaller than the arc center angle of the arc-shaped surface 32 of the sandwiched portion 31, for example, approximately 60 degrees.

  Next, the operation of the sorting apparatus 1 will be described.

  When the article W is supplied onto the conveying means 3, the article W is placed on the placing plate portion 42 of the slat 2 moving in the conveying direction A and is conveyed in the conveying direction A.

  Here, when the article W is not sorted on the branch conveyance means 4, the article W is conveyed by the slat 2 as it is in the conveyance direction A without being pushed out by the extruded body 5.

  On the other hand, when the article W is to be sorted on the branch conveyance means 4, the article W intersects the conveyance direction A by the extruded body 5 that slides along the longitudinal direction with respect to the slat 2. It is pushed out in the direction and sorted from the slat 2 onto the branch conveying means 4.

  And according to the sorting apparatus 1, the articles | goods W which should be sorted can be sorted appropriately by the sliding with respect to the slat 2 of the extrusion body 5 to the direction which cross | intersects the conveyance direction A. FIG.

  Further, the mounting plate portion 42 of the slat 2 is provided with a rotation restricting end portion 47 that controls the rotation of the extruded body 5 around the central axis X with respect to the slat 2 by engagement with the extruded body 5. Since it is formed thicker than the plate body portion 46, the rotation of the extruded body 5 can be appropriately restricted by the rotation restricting end portion 47, and the vibration of the extruded body 5 can also be suppressed.

  Further, since the guide portion 43 of the slat 2 has a plurality of guide plate portions 55 having an arcuate cross section arranged at intervals on an imaginary circle centered on the central axis X, the extruded body 5 is centered with respect to the slat 2. It can be smoothly rotated around the axis X.

  The slat 2 is substantially thin (for example, a portion other than the rotation restricting end portion 47 of the slat 2), for example, a thin plate having a thickness of 1.5 mm. The weight of the slat 2 is light and can be easily reduced in weight.

  Further, since the slat 2 and the chain 11 are connected to each other only through an inexpensive bush 21, not only the assembling work is easy, but also the manufacturing cost can be reduced.

  Moreover, since the main-body part 41 of the slat 2 has the some cylindrical part 40, even if the slat 2 is thin-walled, it has intensity | strength more than desired and can prevent malfunctions, such as a deformation | transformation of the slat 2.

  Furthermore, since the main body portion 41 of the slat 2 has a curved plate-like connecting portion 51 that connects a plurality of cylindrical portions 40, for example, a configuration in which both cylindrical portions 40 are connected to each other by a flat plate-like connecting portion, etc. Compared to the above, not only is the strength strong, but the accuracy of the circle of the cylindrical tubular portion 40 is good.

  For example, FIG. 6 is a cross-sectional view of a mold for producing the slat 2 by extrusion molding of a metal such as aluminum, and 60 in this figure is a fixed mold fixed to a container in which a metal material is put. 61 is a first core and 62 is a second core.

  In the cylindrical tubular portion 40, a portion formed by a gap (a portion indicated by a vertical line in FIG. 6) a between the fixed mold 60 and the first core 61 is a gap a Since the metal material is stably extruded from, high accuracy comes out.

  On the other hand, in the cylindrical tubular portion 40, a portion formed by a gap (a portion with a horizontal line in FIG. 6) b between the first core 61 and the second core 62 is the gap b. Because the extrusion of metal material from is unstable, high accuracy is difficult to get out.

  Therefore, by increasing the gap a and shortening the gap b, it is possible to improve the accuracy of the circle as a whole of the cylindrical portion 40 in which a and b are combined.

  For this reason, the connecting portion 51 of the main body portion 41 of the slat 2 is a curved portion formed by an arc-shaped portion 51a bent at both ends in the short direction and a flat plate-shaped portion 51b between the both arc-shaped portions 51a. As a result, the accuracy of the circle of each cylindrical portion 40 is good.

  The slat 2 is not limited to the shape shown in FIG. 4, and may have a shape shown in FIGS. 7 to 11, for example.

  In the slat 2 shown in FIG. 7, the cylindrical portion 40 of the main body 41 is formed in a polygonal cylindrical shape, for example, a rectangular cylindrical shape. For example, the cylindrical portion 40 may be formed in an elliptical shape.

  In the slat 2 shown in FIG. 8, each guide portion 43 does not have the guide plate portion 55 having an arcuate cross section and is constituted by a guide portion 71 having a square cross section. Note that the cross-sectional shape of the guide portion 71 may be, for example, a rectangular shape or a circular shape.

  In the slat 2 shown in FIG. 9, the cylindrical portion 40 of the main body portion 41 is formed in a discontinuous cylindrical shape having cutout portions at a plurality of locations in the circumferential direction. A guide portion 43 protruding from each cylindrical portion 40 is constituted by a guide portion 72 having a U-shaped cross section. Note that the cross-sectional shape of the guide portion 72 may be, for example, U-shaped or V-shaped. Further, for example, the guide portion 72 may be provided so as to protrude from the outer peripheral surface of the continuous cylindrical portion 40.

  In the slat 2 shown in FIG. 10, each guide portion 43 has one guide plate portion 55 having a semicircular cross section (including a substantially semicircular shape).

  In the slat 2 shown in FIG. 11, each guide portion 43 has a plurality of, for example, two guide plate portions 55 each having an arc shape in cross section, and the end portions in the arc direction of each guide plate portion 55 are tubular via connection portions 56. Connected to portion 40. Note that the connecting portion 56 may not have a plate shape but may have a triangular cross section.

  Further, for example, in order to improve the strength, the entire mounting plate portion 42 of the slat 2 is formed relatively thick, and this thick mounting plate portion 42 is formed at the upper end portion of the cylindrical portion 40 of the main body portion 41. A structure provided integrally may be used.

  Furthermore, the configuration is not limited to the configuration in which the connecting portion 51 of the main body 41 is positioned above the line L, and for example, a configuration in which the flat plate-like portion 51b of the connecting portion 51 is positioned below the line L may be used.

  Further, for example, the arc-shaped portion 51a may be configured to extend obliquely downward from the short-side end of the flat plate-shaped portion 51b of the connecting portion 51. For example, the inclined portion extends instead of the arc-shaped portion 51a. The structure etc. which took out and were connected to the upper part of the cylindrical part 40 may be sufficient.

  FIG. 12 is an explanatory diagram of the shape of the guide part (guide body) 43 of the slat 2.

  As shown in FIG. 12A, in principle, the guide portion 43 of the slat 2 is desired to be in contact with and supported by the lower surface and the side surface of the arcuate surface (guided surface) 32 of the extruded body 5.

  The hatched portion shown in FIGS. 12B and 12C is a region necessary for abutting against the extruded body 5 during forward and reverse rotation (up and down rotation). Note that α in FIG. 12B is approximately 23 degrees, for example, and β in FIG. 12C is approximately 5 degrees, for example.

  Then, these hatched portions are combined, and at least the hatched portion shown in FIG. 12 (d) is required.

  Therefore, a little reserve is provided in the longitudinal direction of the shaded portion shown in FIG. 12D to complete the guide portion 43 shown in FIG. And since the guide part 43 has the guide plate part 55 of two predetermined lengths in this way, the floating of the extrusion body 5, a fall, and rattling can be prevented appropriately.

  Although several embodiments of the present invention and modifications thereof have been described, the above-described embodiments and modifications can be appropriately combined without departing from the gist of the present invention.
