An electromagnet and a magnet are arranged at the downstream side of the branch rail with the main rail. When conveying an article in the branching direction, the electromagnet is energized to attract the rotating body, and then moved along the magnet to guide the branching rail (see, for example, Patent Document 1).
Japanese Patent Laid-Open No. 6-227649 (page 4, FIG. 1) Japanese Patent Laying-Open No. 2001-10718 (FIG. 1) Japanese Patent Laid-Open No. 9-52621 (FIG. 1)

  However, according to the above-described conventional configuration, the rotating body is guided between the pair of left and right guide rail side walls in the guide rail slightly upstream of the branching portion. In this case, the rotating body is separated (displaced) from the electromagnet. ) When guided on the side, there is a possibility that the suction of the rotating body by the electromagnet is disturbed. In addition, when sucked, the rotating body is guided in contact with the yoke. In this case, the rotating body formed of a ferromagnetic body is heavily worn, and the replacement frequency of the expensive rotating body is high. In some cases, replacement is made in units of sliding members.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a conversion facility that can always favorably distribute by width-shifting and that can eliminate the wear of the guided body during the allocation.

  In order to achieve the above-mentioned object, the conversion equipment according to claim 1 of the present invention is attached to a pair of left and right endless rotating bodies arranged along the main transport path, and a large number of them are attached between these endless rotating bodies, and An article support body whose length direction is orthogonal to the main transport path, and an article lateral push body that is externally fitted to and guided by the article support body, are provided at a lower portion of the article lateral push body. A conversion facility provided with a guided body and a guide device for guiding the guided body on the main body frame side, wherein the article laterally pushing body is displaced up and down with respect to the guided body. A narrowing portion is provided, and near the starting end of the guide device, there is provided a sorting means for sorting the guided body in a linear direction or in a lateral direction, and the sorting means is arranged on the upper side and the lower side. The width adjustment part is covered. It is obtained by, comprising the freely right and left pair of rotating bodies acting on ridge.

  Therefore, according to the first aspect of the present invention, the article support group is moved on the main conveyance path by the movement of both endless rotating bodies, thereby conveying the article supplied on the article support group at the start end on the main conveyance path. Can do. Then, by guiding the guided body straightly by the guide device, the article lateral pressing body does not act on the article, and the article can be conveyed in a straight line on the main conveyance path. In addition, by guiding the guided body to the side by the guide device, the article lateral pushing body is moved in the length direction of the article support body, thereby laterally pushing the article and laterally outward of the main conveyance path. You can pay out. At that time, the straight line and the inclined line can be distributed by the distributing unit. That is, first the width-adjusted part enters between the rotating bodies of the width-adjusting part, and the width-adjusted part can be automatically corrected while rotating the rotating body, so that regardless of the state where the guided object is offset The width-adjusting portion automatically corrects the width-alignment so that the guided body can be aligned with the sorting portion.

Furthermore, the conversion equipment according to claim 4 of the present invention is the structure according to any one of claims 1 to 3, wherein the width-adjusted portion is in a rectangular block shape, and both sides of the rotating body of the width-adjusted portion are arranged on both sides. The surfaces are opposed to each other.

  Therefore, according to the invention of claim 4, when the width-adjusted portion is located between both rotating bodies, both side surfaces come into contact with the rotating body, and the width-adjusted portion is automatically adjusted while rotating the rotating body. Correction can be made, and thereby the guided body can be aligned with the distributing portion. At this time, the width-adjusting portion is in the form of a block, so that wear is unlikely to occur.

  Moreover, in the conversion equipment according to claim 5 of the present invention, in the configuration according to claim 4, the rectangular block-shaped narrowing portion has a narrow front end and a rear end equivalent to the width of the two rotating bodies. As a wide shape, both sides are inclined and formed.

  Therefore, according to the fifth aspect of the present invention, when the front end of the width-adjusted portion enters between the rotating bodies of the width-adjusted portion, the front end is narrow and narrow with respect to the approximate width. Therefore, the front end can be inserted between the rotating bodies regardless of the offset state. As the width-adjusted portion moves, the inclined side surface on the offset side comes into contact with the rotating body, and the width-adjusted portion moves to the counter-shift side. Therefore, when the rear end of the width-adjusted part is positioned between the two rotating bodies, the rear end is wide and is equivalent to the width of the adjoining, so that both inclined side surfaces are in contact with the rotating body and the width-adjusted part. Can be corrected automatically.

  According to the first aspect of the present invention described above, by moving the article support group on the main transport path by the movement of both endless rotating bodies, the article supplied on the article support group at the start end is moved on the main transport path. Can be transported by. Then, by guiding the guided body straightly by the guide device, the article lateral pressing body does not act on the article, and the article can be conveyed in a straight line on the main conveyance path. In addition, by guiding the guided body to the side by the guide device, the article lateral pusher is moved in the length direction of the article support, and the article is pushed laterally to the outside of the side of the main conveyance path. Can be put out. At this time, the distribution between the straight line and the inclined line can be performed by a distribution unit.

  That is, the width-shifted portion first enters between the rotating bodies of the width-aligned portion, and the width-shifted portion can be automatically corrected while rotating the rotating body, thereby regardless of the state where the guided body is offset, In the width aligning portion, the width aligning can be automatically corrected, the guided body can be accurately aligned with the distributing portion, and the distribution can always be suitably performed. In addition, since the guided body is not related to the width-shifting action, there is no wear due to the width-shifting action, so that the replacement frequency of the expensive guided body or the replacement frequency in the unit of the article laterally pressing body can be lowered.

  According to the second aspect of the present invention described above, the inner side surface of the guided body, that is, the inner side surface of the magnetic body is obtained by automatically correcting the width shifting portion while rotating the rotating body of the width shifting portion. Can be aligned with the electromagnet. That is, regardless of the state in which the guided body is offset, the width-adjusting portion automatically corrects the width, and the inner surface of the magnetic body in the guided body can be accurately aligned with the electromagnet. When moved in such a state of alignment, the guided body can be moved with the inner surface of the magnetic body in contact with the electromagnet. At the time of linear distribution, the electromagnet is off and no attracting action occurs, and therefore the guided body is not attracted and guided to the electromagnet side and can go straight. Further, in the inclined distribution posture, the electromagnet is turned on to generate an attracting action, and therefore the guided body can be guided to be tilted sideways in the attracted state. At that time, since the guided body having the outermost layer as a magnetic material is not related to the width-shifting action, there is no wear due to the width-shifting action. The replacement frequency in units of can be reduced.

And according to Claim 3 of the above-mentioned this invention, the forced width alignment can be performed stably via a width-shifting part because the width-shifting part is located in the article side pushing body side. .
According to the fourth aspect of the present invention described above, when the width-adjusted portion is positioned between the two rotating bodies, both side surfaces come into contact with the rotating body, and the width-adjusted portion is automatically moved while rotating the rotating body. Thus, the guided body can be aligned with the sorting portion. At this time, since the width-adjusting portion is in a block shape, it can be made hard to cause wear.

  In addition, according to the fifth aspect of the present invention, when the front end of the width-adjusted portion enters between the rotating bodies of the width-adjusted portion, the front end is narrow and narrow with respect to the approximate width. The amount can be absorbed, and therefore, the front end can be smoothly and reliably inserted between the rotating bodies regardless of the deviation. When the width-adjusted portion moves, the inclined side surface on the offset side comes into contact with the rotating body, and the width-adjusted portion can be moved to the opposite side. Therefore, when the rear end of the width-adjusted part is positioned between the two rotating bodies, the rear end is wide and is equivalent to the width of the adjoining, so that both inclined side surfaces are in contact with the rotating body and the width-adjusted part. Can be automatically adjusted.

Further, by making the rear end portion of the top plate 86 into a convex arcuate corner surface 86d, for example, carrying means for carrying-in or carrying-out (not shown by a belt conveyor device or the like) are arranged before and after the conversion equipment. In such a case, when the article laterally pressing body 80 that is being reversed is in contact with the belt or the like due to a malfunction or the like, the corner surface 86d can be in contact with the belt or the like to prevent damage to the belt or the like.

  A recess 89 is formed over the entire length in the left-right direction on the upper surface of the top plate member 86, at the boundary between the front end 81A and the top plate member 86, and above the left-right direction rib plate material 87. Therefore, for example, when the lateral pushing action portion 80 is resin-molded, the design can be improved by effectively using the concave portions 89 formed over the entire length in the left and right direction rib plate material 87 group.

  Further, when the front end portion 81A of the upper plate member 81 and the top plate member 86 (lateral push acting portion 85) are viewed in plan (side shape), the left and right corners of the front end portion 81A are formed on the arcuate side surface 81b having a convex arc shape. In addition, a concave arc-shaped side surface 81c is formed continuously in a concave arc shape and abruptly enters the rear end thereof. Further, both side surfaces of the top plate 86 are formed so that the front end portion connected to the concave arcuate side surface 81c is wide and the width is gradually narrowed to become the narrow rear end portion, that is, standing upright and rear with respect to the front portion. Is formed on a laterally inclined surface 86f inclined toward the other side surface. As a result, the top plate 86 is formed in a trapezoidal plate shape with an inclination angle θ of 30 degrees in plan view, and the portion of the upper plate member 81 excluding the front end portion 81A and the rib plate members 87 and 88 are in the trapezoidal plate shape.

The movement of the both endless chains 40 causes the article support 50 group to be supported and guided to the upper support surfaces 18a and 26a of the guide rail portions 18 and 26 via the guide rollers 70, and to both guide rails via the side rollers 71. It can move in a stable state by being guided by the lateral guide surface 18b of the portion 18. As a result, the article support 50 group circulates and moves, so that the article 160 supplied onto the starting article support 50 group can be conveyed on the main conveyance path 45. During transport, the movement of both endless chains 40 in the forward path is performed below the cover body 140 and above the lubricating oil receiver 13, and the movement of both endless chains 40 in the return path is performed by the upper end extension 29. And above the lubricating oil receiver 25.

  When such conveyance is performed, the article laterally pressing body 80 that moves integrally with the article support 50 group moves the guided portion 96 by guiding the guide roller 108 to the guide device groups 110 and 116. The article support 50 is reciprocated in the longitudinal direction 51 of the article support 50, or is moved linearly along the main transport path 45 together with the article support 50.

  That is, for example, the guide roller 108 guided to the one-side starting end guide portion 111A is guided straight when the sorting means 130A is in the linear sorting state, and straightly travels while being guided to the intermediate guide portion 115A, and then terminates. It will be guided to the guide part 114A. As a result, the article laterally pressing body 80 does not act on the article 160, and the article 160 is conveyed in a straight line on the main conveyance path 45. The same applies to the opposite side, and the guide roller 108 of the start end guide portion 111B is guided by the intermediate guide portion 115BA from the sorting means 130B and moves straight to the end guide portion 114B.

  Further, the guide roller 108 guided to the one-side starting end guide portion 111A is inclined and guided inward when the distribution means 131A is in the inclined distribution state, and is guided and moved inward by the inward movement guide portion 112A. After that, it moves to the outer movement guide part 113B via the upper switching means 125, and is guided to the outer movement guide part 113B and moved outward, and then guided to the terminal guide part 114B. As a result, the group of article laterally pushing bodies 80 traverses the main transport path 45 while moving in the transport direction, so that the lateral side pushing action portion 85 on the other side laterally acts on the article 160 to cause the article 160 to move. While changing its direction, it is branched and moved with respect to the main transport path 45, and handed over to the other branch conveyor 151B.

  The same applies to the opposite side, and the guide roller 108 of the start end guide portion 111B is guided by the sorting means 130B, the inner movement guide portion 112B, the upper switching means 1250, the outer movement guide portion 113A, and the end guide portion 114A. The lateral pushing action portion 85 on one side of the push body 80 group laterally acts on the article 160 via the transverse pushing abutting member 90, and the article 160 is delivered to one branching conveyor 151A.

  The guide roller 108 that has reached the end portions of the end guide portions 114A and 114B in this manner is guided by the reverse guide bodies 138A and 138B and is reversed. The return path guide device 116 is first guided to the inner movement guide portions 117A and 117B, moved to the center portion, and then distributed to the left and right by the lower switching means 126, and then moved outward by the guidance of the outer movement guide portions 118A and 118B. Moved to. After that, after being guided and reversed by the reversing guide bodies 137A and 137B, it is moved to one of the start end guide portions 111A and 111B.

  During such reversal, the front and rear side brackets 61 are relatively expanded and contracted, whereby the fitting portion 66 and the ring body 75 are slidably moved. 66 and the resin ring body 75, that is, sliding contact made of a material having a different fitting surface, for example, wear and noise compared to sliding contact made of the same material for the fitting surface. The occurrence of can be reduced.

The linear distribution state and the inclined distribution state in the distribution means 130A and 130B described above are performed as follows. That is, for example, as shown in the imaginary line A of FIG. 1 and FIG. 16, the guide roller 108 is in a rotationally guided state in contact with the guide plate 122 in the one-side start guide portion 111A, that is, the guide roller 108 and the covered roller. In a state where the width aligning portion 106 is displaced (displaced) toward the guide plate 122, first, the front end of the width aligned portion 106 enters between the rollers 132A of the width aligning portion 131A. At this time, the front end has a narrow width W ₁ and [W ₁ <W ₃ ] which is narrower than the shift width W ₃ , so that the amount of displacement can be absorbed by the difference, so that the front end enters between the rollers 132A. Is always performed smoothly and reliably regardless of the offset.

When the width-adjusted portion 106 moves, the inclined side surface 106a on the offset side comes into contact with the roller 132A on the offset side, and the width-adjusted portion 106 is moved to the counter displacement side. Therefore, when the rear end of the width-adjusted portion 106 is positioned between the two rollers 132A, the rear end is wide W ₂ and has the same shape as the shift width W ₃ [W ₃ ≧ W ₂ ]. As shown in FIG. 17, both the inclined side surfaces 106 a and 106 b come into contact with the roller 132 </ b> A, and the width-adjusted portion 106 is automatically corrected in the width alignment (centering shape). Thereby, the inner surface of the guide roller 108, that is, the inner surface of the magnetic body 108a can be aligned with the rectilinear attracting action surface 135m of the electromagnet 135A. That is, regardless of the state in which the guide roller 108 is offset in the starting end guide portion 111A, the width-adjusting portion 131A automatically corrects the width, and the inner surface of the magnetic body 108a in the guide roller 108 is the straight-adsorption acting surface of the electromagnet 135A. It can be accurately aligned to 135m.

  Note that, when the width adjusting portion 131A is aligned, both the inclined side surfaces 106a and 106b come into contact with the roller 132A, so that the roller 132A rotates (rotates) with respect to the longitudinal axis 133A. Since it is in a block shape, wear is unlikely to occur. Further, since the guide roller 108 having the magnetic body 108a as the outermost layer is not related to the width-shifting action, there is no wear due to the width-shifting action, and therefore the replacement frequency of the expensive guide roller 108 or the article laterally-pressing body 80 is eliminated. The replacement frequency in units of can be reduced.

  When the inner surface of the guide roller 108, that is, the inner surface of the magnetic body 108a is moved in a state of being aligned with the rectilinear attracting action surface 135m of the electromagnet 135A by the above-described width adjustment, the imaginary line B in FIG. As shown, the guide roller 108 can be idled in a state where the inner surface of the magnetic body 108a is in contact with the rectilinear attracting action surface 135m.

  When the linear distribution is performed, the electromagnet 135A is off and no attracting action is generated. Therefore, the guide roller 108 is in contact with the rectilinear attracting action surface 135m, but is not attracted. It goes straight without being attracted and guided to the 135n side. Next, the lower end protruding portion of the roller shaft 107 is guided by the rectilinear guide surface 136m of the sorting guide body 136A, so that the guide roller 108 (the article laterally pressing body 80) moves straight as shown by an imaginary line C in FIG. You will be guided.

  Further, in the inclined distribution posture, the electromagnet 135A is turned on and an attracting action is generated. Therefore, the guide roller 108 rotates in contact with the rectilinear attracting action face 135m in an attracted state. Inclined and guided inward while contacting and swinging on the 135an side. Then, the lower end protruding portion of the roller shaft 107 is guided by the inclined guide surface 136n of the sorting guide body 136A, so that the guide roller 108 (the article laterally pressing body 80) can move to the inner side as shown by an imaginary line D in FIG. Will be guided to the slope. The above operation is performed in the same way in the other-side distribution means 130B.

  As described above, when the article lateral pusher 80 is moved, when the article lateral pusher 80 is in a no-load state without performing the lateral push movement or in a light load state in which the light article 160 is laterally pushed and moved, both upwards The abutting portion 101a of the tongue piece body 101 abuts on the flat surface 53a of the convex portion 53 from below, and the lower guided surfaces 96b and 97b are pressed against the lower guide surfaces 59b and 60b by the pressing force due to the elastic repulsive force. The contact portions 103a of both forward tongue pieces 103 abut against the front and rear guide surfaces 59a of the guide portion 59 from the inside, and the front and rear guided surfaces 97a are pressed against the front and rear guide surfaces 60a of the guide portion 60 by the back pushing force due to the elastic repulsion force. It will be.

  Thereby, in the reciprocating movement of the article laterally pressing body 80 in the longitudinal direction 51 of the article support 50, the contact portion 101a is in elastic contact with the flat surface 53a and is in sliding contact, and the lower guided surfaces 96b and 97b are lower. The abutting portion 103a is elastically abutted against and slidably contacted with the front and rear guide surfaces 59a, and the front and rear guided surface 97a is abutted against and slidably contacted with the front and back guide surfaces 60a. .

  Further, when the article lateral pusher 80 is in a heavy load state in which the heavy article 160 is laterally moved, the article lateral pusher 80 is slightly displaced with respect to the article support 50 by the lateral push bias load. That is, on the contact side with the article 160, the guided portions 96 and 97 rise against the elastic force of the upward tongue piece 101, and the upper guided surfaces 96 c and 97 c are flat surfaces 53 a of the convex portion 53. The front and rear guided surfaces 96a abut against the front and rear guide surfaces 59a from the inner side against the elastic force of the forward tongue piece 103 on the side opposite to the side in contact with the article 160. Become.

  As a result, the reciprocating movement of the article laterally pressing body 80 in the longitudinal direction 51 of the article support 50 causes the upper guided surfaces 96c and 97c and the contact portion 101a to come into sliding contact with the flat surface 53a, and the lower guided surface. 96b and 97b are in contact with the lower guide surfaces 59b and 60b to be in sliding contact, the front and rear guided surfaces 96a and the contact portion 103a are in contact with and in sliding contact with the front and rear guide surfaces 59a, and the front and rear guided surfaces 97a are in contact with the front and rear guide surfaces 60a. This can be done in a state of abutting and sliding.

  Accordingly, the reciprocating movement of the article laterally pressing body 80 is guided and fitted to the guide portions 59 and 60 of the article support 50 through the front and rear guided portions 96 and 97, that is, suitable. In a state where sliding friction is generated, there is no backlash and the posture (orientation) is not greatly changed, and it can always be performed stably. Further, the group of tongue pieces 101 and 103 are formed so as to be distributed to both ends in the length direction 51, so that the movement of the article laterally pressing body 80 causes the same suitable sliding friction in both reciprocation. It can be done in the state.

  In addition, a downward convex portion 53 is formed on the lower surface of the article placing plate portion 54, a lower portion of the convex portion 53 is formed on the flat surface 53a, and upper surfaces of the guided portions 96 and 97 are formed on the flat surface. By forming the upper guided surfaces 96c and 97c facing the lower side of 53a, the upper guided surfaces 96c and 97c move on the flat surface 53a when the article laterally pressing body 80 group moves in the length direction 51. Since the sliding is performed, the movement can be performed in a state where the frictional resistance is small, so that the intended movement can be smoothly performed without damaging the article laterally pressing body 80 and without wearing the article support 50 side.

  As described above, when the article laterally pressing body 80 group moves in the transport direction and crosses the main transport path 45, the laterally pushing action portion 85 is laterally pushed to the article 160, and the article 160 is branched and moved. At this time, the article 160 is supported between the flat surfaces 52a of the convex portion 52 group and slides on the flat surfaces 52a. Therefore, the desired branching movement can be performed smoothly without damaging the article 160 and without wearing the article support 50 side.

  The side portion of the lateral pushing action portion 85 is laterally abutted in a state where the left and right corners of the front end portion 81A are formed on the arc-shaped side surface 81b, and the laterally pushing contact surface 90a continues to the rear end of the arc-shaped side surface 81b. Since the member 90 is provided, almost the entire length of the side portion of the lateral pushing action portion 85 can be used as the lateral pushing action surface, so that stable lateral pushing movement can be achieved, and the front and rear article side pushing bodies 80 can be provided. The gap S (refer to FIG. 11) between the lateral pushing action portions 85 in FIG. 11 can be reduced to enable the intended lateral pushing movement in a state where the article 160 does not enter.

  Further, the upper part of the lateral pushing action part 85 is formed with an intermediate part in the front-rear direction on an inclined upper surface 86a that extends forward and downward, and is connected to the inclined upper surface 86a at the front end part with respect to the inclined upper surface 86a. By forming the start-side concave arcuate upper surface 81a having a gentle angle, for example, when the article 160 is sandwiched between the front and rear article laterally pressing bodies 80 at the start of the lateral pushing, the article 160 is placed. First, the concave arcuate upper surface 81a having a gentle angle is smoothly submerged, and the article 160 is lifted by the inclined upper surface 86a. Thereby, the intended lateral pushing movement can be made possible without being pinched, and thus the article 160 and the article lateral pushing body 80 can be prevented from being damaged. In addition, since the left and right corners of the front end portion 81A are formed on the arc-shaped side surface 81b, the dive under the article 160 can be performed more smoothly.

  As described above, when the article laterally pressing body 80 group moves in the transport direction and crosses the main transport path 45, the laterally pushing action portion 85 is laterally pushed to the article 160, and the article 160 is branched and moved. At this time, the article 160 on the article support 50 is placed above the cover 140 fixed to the upper frame member 10 so that the upper part of the endless chain 40 is closed. By climbing over, it is possible to prevent dust or the like adhering to the article 160 from falling to the endless chain 40 side.

  At this time, the uppermost surface 142a of the cover body 140 is positioned at the same level as the upper surface 54a of the article support 50, and the branch conveyance surfaces 150a and 150b of the branch paths 150A and 150B are placed on the same plane as the uppermost surface 142a. By being positioned at a single level, the article 160 from the article support 50 side can smoothly branch and move from the top surface 142a to the branch conveyance surfaces 150a and 150b without rattling up and down. Thus, damage to the article 160 and generation of noise can be prevented.

  Further, by forming the inner end portion of the cover body 140 on the inclined upper surface 142a that descends with respect to the upper surface 54a, for example, the article 160 itself is soft or the package body of the article 160 is soft, and the upper surface is deformed due to its bending. Even if it is in contact with the hanger 54a, when it moves from the upper surface 54a to the uppermost surface 142a at the time of branching movement, it is first received by the inclined upper surface 142a and guided to the uppermost surface 142a side. The cover body 140 can be reliably branched and moved without entering under the cover body 140.

In addition, since the concave portion 144 is formed on the inner surface side of the corner portion 143 formed by the side plate portion 141 and the upper plate portion 142 of the cover body 140, the article 160 from the article support body 50 side contacts the uppermost surface 142a. When there is a large impact, the upper plate portion 142 is bent through the recess 144, so that the impact can be buffered.
