The guiding means 37 has a straight guide rail 38 for guiding the guided portion 34 of the pusher 5 along the conveyance direction A, and a branch rail 39 for guiding the pusher 5 in a direction inclined to the conveyance direction A. The guided portion 34 slides the push-out portion 5 in the direction intersecting (orthogonal) with the conveyance direction A with respect to the slat 2 (see FIG. 1).

Further, a switching means (not shown) is disposed upstream of the guide start end portion of the branch rail 39, and the guide portion 34 of the pusher 5 is linearly advanced toward the straight guide rail 38 side. Or, the moving direction of the guided portion 34 is switched to the branch rail 39 side. The switching means is constituted by, for example, a rotation guide for guiding the guided portion 34, and a driving body (rotary solenoid) for rotating the rotation guide in accordance with the discrimination information.

Here, as shown in Fig. 3 and Fig. 4, the slat 2 The main body portion 41 has a plurality of cylindrical portions 40 having a cylindrical shape in a front-rear direction, for example, which are separated from each other, and a mounting plate portion 42 integrally provided in the main body portion. 41 is a top portion, and a mounting portion having a long shape in the left-right direction and a rectangular plate shape is placed on the upper surface; and a guide portion 43 having a long shape and a protruding shape in the left-right direction is slid on the slat 2 of the push-out body 5 The pusher 5 is guided at the time and when rotated.

In other words, each of the slats 2 is an elongated body that is integrally formed into a thin wall by extrusion molding of a metal such as aluminum, and is composed of the main body portion 41, the placing plate portion 42, and the guiding portion 43.

The mounting plate portion 42 is formed by restricting engagement between the push-out body 5 and the push-piece body 5 to the end portions on both end sides in the short-side direction in which the slats 2 are rotated up and down in the short-side direction. The middle portion other than the end portions is thicker.

In other words, the placing plate portion 42 is constituted by a placing plate main body portion 46 and a rotation restricting end portion 47 which are long in the left-right direction and have a rectangular plate shape, and the rotation restricting end portion 47 is connected to the mounting portion. Both ends of the plate body portion 46 in the short side direction are formed thicker than the thin wall-shaped mounting plate body portion 46.

The thickness of the mounting plate main body portion 46 is substantially constant throughout the entire mounting plate main portion 46, and is smaller than the thickness of the rotation restricting end portion 47. On the other hand, the thickness of the rotation restricting end portion 47 is gradually reduced from the proximal end side toward the distal end side, and the upper end surface of the rotation restricting end portion 47 is formed into a curved surface shape.

Further, although the short side end of the board main body portion 46 is placed The upper surface of the portion and the upper surface of the rotation restricting end portion 47 are smoothly and continuously without any step, but the lower surface of the end portion in the short side direction of the placing plate main portion 46 and the lower surface of the rotation restricting end portion 47 are A step 48 is formed between the lines.

Further, the placing plate main body portion 46 has two arc-shaped portions 46a which are in an upwardly bulging shape in contact with the lower surface of the article W and have a semicircular cross section (including a substantially semicircular shape), and these two arc shapes The portions 46a are connected to each other by a curved plate-shaped connecting plate portion 46b.

Then, the pusher 5 performs the operation shown in FIG. 5 on the slats 2. Fig. 5(a) shows a state when the slat 2 is hung on the sprocket (when the moving direction is changed) toward the carrier side or the return side; Fig. 5(b) is a display panel The state in which the strip 2 travels in the direction opposite to the transport direction in the transport direction or the return side; and Fig. 5(c) shows the state in which the slat 2 passes through the catenary on the return side (when the direction of movement is changed) .

In Fig. 5(a), the abutment engagement of the rotation restricting end portion 47 of the mounting plate portion 42 of the slat 2 with the pushing portion 33 of the pusher 5 and the contact with the guiding portion 43 can be achieved. To limit the rotation of the pusher 5 to the slats 2.

In Fig. 5(b), the rotation restricting end portion 47 of the slat 2 can be abutted against the clamped portion 31 of the pusher 5, and the arc portion can be abutted. The contact of the 46a with the push-out portion 33 and the contact of the guide portion 43 with the clamped portion 31 allow the positioning of the pusher 5 to be performed. Furthermore, it can be contacted by the push-out body 5 as a shoe-shaped plate when sliding in the left-right direction. The guide plate portion 55 is provided to prevent the tilting (shaking) of the pusher body 5.

In Fig. 5(c), the abutment of the rotation restricting end portion 47 of the mounting plate portion 42 of the slat 2 and the receiving portion of the pushed portion 31 of the pusher 5 can be abutted and rounded. The abutment of the arcuate portion 46a with the push-out portion 33 and the abutment of the guide portion 43 with the clamped portion 31 restrict the rotation of the pusher 5 to the slat 2.

The main body portion 41 as the base portion has a cylindrical portion 40 formed in a plurality of cylindrical shapes parallel to each other in the direction intersecting the conveying direction A, for example, a cylindrical shape in which both end surfaces are open; The connecting portion 51 is for connecting the two cylindrical portions 40 to each other; and the flat plate-shaped portion 52 is erected on the upper end portion of each of the cylindrical portions 40 and the upper end portion is connected to the mounting plate portion 42. The lower surface of the arcuate portion 46a of the plate body portion 46 is placed.

The tubular portion 40 is formed in a perfect circular shape centering on the horizontal central axis (axis center) X, and is located at one end in the longitudinal direction from the slat 2 and at the other end in the longitudinal direction. Then, the cylindrical portion 22 in which the bushing 21 is fitted is inserted into the inner peripheral side of each end portion in the axial direction of the tubular portion 40, and the flange portion 23 abuts against the end surface of the cylindrical portion 40, The bushing 21 can be positioned by the abutment to the cylindrical portion 40. Further, the fitting hole portion 24 of the bushing 21 to be positioned is rotatably fitted and fitted to the support shaft portion 14 of the chain 11. Thus, each of the plurality of slats 2 can be coupled to the chain 11 only through a plurality of, for example, four bushings 21. In other words, the slats 2 can be placed between the two chains 11 only through the slats 2.

The connecting portion 51 has a circular cross section of 1/4 (including The two arcuate portions 51a are approximately one-fourth of a circle, and the two arc-shaped portions 51a are connected to each other by a flat plate-like portion 51b. The flat portion 51b is positioned above the horizontal line L connecting the two central axes X, and the arcuate portion 51a extends obliquely upward from each end portion of the flat portion 51b in the short side direction. The upper end portion of the arc portion 51a is connected to the upper portion of the cylindrical portion 40.

The plurality of guide plate portions 55 of the guide portions 43 guide the sliding and rotating of the pusher 5 to the slats 2. In other words, when the pusher 5 slides on the slat 2, the pusher 5 is guided by the guide portion 43 and the arcuate portion 46a of the mounting plate portion 42 in a direction orthogonal to the conveyance direction A. Slide the slats 2 to the left and right. Further, when the pusher 5 rotates the slats 2, the pusher 5 is slidably slid with respect to the slat 2 around the central axis X of the tubular portion 40 while being guided by the guide portion 43.

Further, each of the guide portions 43 has a plurality of cross-sectional arc shapes, for example, two guide plate portions 55 which are centered on the central axis X of the cylindrical portion 40 of the body portion 41. The virtual circle is arranged to be spaced apart from each other to guide the push-out body 5, and the central portion (the central portion in the width direction) of the guide plate portion 55 in the arc direction is transmitted through the flat plate along the diameter direction of the cylindrical portion 40. The connecting portion 56 is connected to the outer peripheral surface of the tubular portion 40.

In other words, the guide plate portion 55 of one of the two guide plate portions 55 is provided at the front end portion of the joint portion 56 projecting from the lower end portion of the cylindrical portion 40, and is located at the cylindrical portion 40. Below. Further, the other of the two guide plate portions 55 is provided with a guide plate portion 55. The front end portion of the joint portion 56 projecting from the outer side end portion of the cylindrical portion 40 is located on the outer side of the cylindrical portion 40. Then, the two guide plate portions 55 are slidably coupled to the arcuate surface 32 of the clamped portion 31 of the pusher body 5 in a planar shape. Further, the arc center angle of the arc-shaped guide plate portion 55 is smaller than the arc center angle of the arcuate surface 32 of the clamped portion 31, and is, for example, approximately 60 degrees.

Next, the action of the distinguishing device 1 and the like will be described.

When the article W is supplied to the transport means 3, the article W is placed on the mounting plate portion 42 of the moving slat 2 in the transport direction A and transported toward the transport direction A.

Here, in the case where the article W is not distinguished from the branch conveyance means 4, the article W is not pushed out by the pusher 5, but is conveyed directly by the slat 2 toward the conveyance direction A.

On the other hand, when the article W is divided into the branch conveyance means 4, the article W is pushed out in the direction intersecting the conveyance direction A by the pusher 5 that slides the slat 2 along the longitudinal direction thereof. And it is distinguished from the slat 2 to the branching means 4.

Then, according to the sorting device 1, the article W to be distinguished can be appropriately distinguished by the sliding of the pusher 5 toward the slat 2 in a direction intersecting the conveyance direction.

Further, since the mounting plate portion 42 of the slat 2 is formed such that the rotation restricting end portion 47 is thicker than the placing plate main portion 46, the rotation restricting end portion 47 is restricted by the engagement with the pusher 5. The pusher 5 rotates the slat 2 centering on the central axis X, so the rotation limit can be utilized The end portion 47 is used to appropriately restrict the rotation of the pusher 5, and the vibration of the pusher 5 can also be suppressed.

Further, since the guide portion 43 of the slat 2 has a plurality of guide plate portions 55 having a cross-sectional arc shape arranged at intervals along a virtual circle centered on the central axis X, the pusher 5 can be made. The slat 2 is smoothly rotated about the center axis X.

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

Further, since the slats 2 and the chain 11 are configured to be connected to each other only through the inexpensive bushing 21, not only the assembly work is easy, but also the manufacturing cost can be reduced.

Further, since the main body portion 41 of the slat 2 has a plurality of cylindrical portions 40, even if the slats 2 have a thin wall shape, they have a desired strength or more, and it is possible to appropriately prevent deformation such as deformation of the slats 2.

Further, since the main body portion 41 of the slat 2 has a curved plate-shaped connecting portion 51 for connecting the plurality of cylindrical portions 40, the two cylindrical portions 40 are joined to each other by, for example, a flat connecting portion. The configuration of each other is not only strong, but also the circular precision of the cylindrical tubular portion 40 is also preferable.

For example, Fig. 6 is a cross-sectional view of a mold for manufacturing a slat 2 by extrusion molding of a metal such as aluminum, in which reference numeral 60 is a fixed mold fixed to a container in which a metal material is placed, 61 is the first 1 sand core, 62 is the second sand core.

Then, a portion of the cylindrical tubular portion 40 formed by the gap between the fixed mold 60 and the first core 61 (the portion where the vertical line is applied in FIG. 6) is formed by the metal material. The gap a is stably pushed out, so that it exhibits high precision.

On the other hand, in the cylindrical tubular portion 40, the portion formed by the gap between the first core 61 and the second core 62 (the portion where the horizontal line is applied in FIG. 6) b is formed by the metal. The material is unstable from the ejection of the gap b, so that it is difficult to exhibit high precision.

Therefore, by lengthening the gap a and shortening the gap b, the cylindrical portion 40 which combines a and b as a whole can improve the accuracy of the circle.

In this case, the connecting portion 51 of the main body portion 41 of the slat 2 is an arcuate portion 51a on both end sides in the short side direction which is curved toward the upper side, and is located between the two arcuate portions 51a. The curved shape of the flat portion 51b is such that the circular shape of each of the cylindrical tubular portions 40 is excellent.

Further, the slats 2 are not limited to the shape shown in FIG. 4, and may be, for example, the shapes shown in FIGS. 7 to 11.

In the slat 2 shown in Fig. 7, the tubular portion 40 of the main body portion 41 is formed in a polygonal cylindrical shape, for example, a quadrangular cylindrical shape. Further, for example, the tubular portion 40 may be formed in an elliptical shape.

In the slat 2 shown in Fig. 8, each of the guide portions 43 does not have a guide plate portion 55 having a circular arc shape, but is formed of a guide portion 71 having a square shape in cross section. In addition, the cross-sectional shape of the guiding portion 71, For example, it may be 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 a notched portion at a plurality of portions in the circumferential direction. Then, the guide portion 43 projecting from each of the cylindrical portions 40 is constituted by a guide portion 72 having a U-shaped cross section. Further, the cross-sectional shape of the guiding portion 72 may be, for example, a U shape or a V shape. Further, for example, the guide portion 72 may be protruded from the outer peripheral surface of the cylindrical portion 40 having a cylindrical shape formed continuously.

In the slat 2 shown in Fig. 10, each of the guide portions 43 has a guide plate portion 55 which is formed in a semicircular cross section (including a substantially semicircular shape).

In the slat 2 shown in Fig. 11, each of the guide portions 43 has a plurality of, for example, two-arc-shaped guide plate portions 55, and the end portions of the guide plate portions 55 in the arc direction It is connected to the tubular portion 40 through the connecting portion 56. Further, the connecting portion 56 may not be a plate shape but a cross-sectional triangular shape or the like.

Further, for example, in order to increase the strength, the thickness of the mounting plate portion 42 of the slat 2 may be relatively thick, and the thick-shaped placing plate portion 42 may be integrally provided to the main body portion. The upper end portion of the cylindrical portion 40 of 41.

In addition, the connection portion 51 of the main body portion 41 is not limited to the upper portion than the line L. For example, the flat portion 51b of the connection portion 51 may be located below the line L.

Further, for example, the arcuate portion 51a may be connected from the joint portion A configuration in which the end portion in the short-side direction of the flat portion 51b of the 51 is extended obliquely downward, and the inclined portion may be extended and connected to the upper portion of the tubular portion 40 instead of the arc-shaped portion 51a. Wait.

In addition, FIG. 12 is an explanatory view of the shape of the guide portion (guide body) 43 of the slat 2 .

As shown in Fig. 12(a), in principle, the guide portion 43 of the slat 2 is supported by the lower surface and the side surface of the arcuate surface (guided surface) 32 of the pusher body 5.

The hatched portions shown in Figs. 12(b) and (c) are regions required for abutting against the pusher 5 when the front and back are rotated (up and down rotation). Further, in Fig. 12(b), α is, for example, approximately 23 degrees, and β in Fig. 12(c) is, for example, approximately 5 degrees.

Then, the two oblique line portions are combined, and at least the oblique line portion shown in Fig. 12(d) is required.

Therefore, the longitudinal direction of the hatched portion shown in Fig. 12(d) is slightly prepared, and the guide portion 43 shown in Fig. 12(e) is completed. Then, since the guide portion 43 has the guide plate portions 55 of two predetermined lengths in this way, the floating, falling, and shaking of the pusher 5 can be appropriately prevented.

Further, although the embodiments of the present invention and the modifications thereof have been described, the respective embodiments and the modifications can be combined as appropriate without departing from the scope of the invention.
