各物品支持体５０には、この物品支持体５０に外嵌して案内されることで長さ方向５１に移動自在な物品横押し体８０が設けられ、これら物品横押し体８０は、下位の矩形筒状部分と上位の横押し作用部８５とにより構成されている。すなわち各物品横押し体８０は、前記物品載置板部５４に上側から対向される扁平状の上板材８１と、この上板材８１の前端から下方かつ後方に延びることで前板部５７に外側から対向される前板材８２と、前記上板材８１の後端から下方かつ前方に延びることで後板部５８に外側から対向される後板材８３と、前板材８２と後板材８３の下端間に位置されることで前位円弧部５７Ａや後位円弧部５８Ａに下側（下方）から対向される扁平状の底板材８４とにより矩形筒状部分が形成されている。   Each article support 50 is provided with an article laterally pushing body 80 that is guided by being fitted around the article support 50 and is movable in the length direction 51. It is comprised by the rectangular cylindrical part and the high-order side pushing action part 85. FIG. That is, each article laterally pressing body 80 has a flat upper plate 81 facing the article placing plate 54 from above, and extends downward and rearward from the front end of the upper plate 81 to the outside of the front plate 57. A front plate member 82 opposed to the rear plate member 83, and a rear plate member 83 that extends downward and forward from the rear end of the upper plate member 81 to face the rear plate portion 58 from the outside, and between the lower ends of the front plate member 82 and the rear plate member 83. A rectangular cylindrical portion is formed by the flat bottom plate member 84 facing the front arc portion 57A and the rear arc portion 58A from the lower side (downward) by being positioned.

そして前記上板材８１の上面側（上方）に横押し作用部８５が設けられている。すなわち横押し作用部８５は、上板材８１の前端部８１Ａを除いた残部（扁平状部）の上方を覆う天板材８６と、この天板材８６を上板材８１に連結する前後一対（単数または複数）の左右方向リブ板材８７、ならびに左右中央（単数または複数）の前後方向リブ板材８８とから形成されている。ここでリブ板材８７，８８群により横押し作用部８５の強度アップを図っている。   A lateral pushing action portion 85 is provided on the upper surface side (upward) of the upper plate member 81. That is, the lateral pushing action portion 85 includes a top plate member 86 that covers the upper part of the remaining portion (flat portion) excluding the front end portion 81 </ b> A of the upper plate member 81, and a pair of front and rear (single or plural) that connect the top plate member 86 to the upper plate member 81. ) Left and right direction rib plate material 87 and left and right center (single or plural) front and rear direction rib plate material 88. Here, the strength of the lateral pushing action portion 85 is increased by the rib plate members 87 and 88 group.

その際に、上板材８１の前端部８１Ａと天板材８６との上面を側面視（上面形状）したとき、前端部８１Ａの部分は、凹円弧状でかつ小さい傾斜で次第に上昇するくちばし状の始端凹状上面（始端上面の一例）８１ａに形成され、天板材８６の前部は、直線状でかつ始端凹状上面８１ａよりも大きい傾斜角度で次第に上昇する傾斜状上面８６ａに形成され、天板材８６の中間部は、凸円弧状でかつ次第に上昇する前凸円弧状上面８６ｂと、凸円弧状でかつ頂部を形成する後凸円弧状上面８６ｃとに形成され、天板材８６の後端部分は、凸円弧状でかつ急激に下降するコーナー面８６ｄと、凸円弧状でかつ急激に下降する凸円弧状後面８６ｅに形成されている。   At that time, when the upper surfaces of the front end portion 81A of the upper plate member 81 and the top plate member 86 are viewed from the side (upper shape), the front end portion 81A has a concave arc shape and a beak-shaped start end that gradually rises with a small inclination. The top surface of the top plate member 86 is formed in a concave top surface (an example of the top surface of the start end) 81a, and is formed in a slanted top surface 86a that is linear and gradually rises at an inclination angle larger than that of the top end concave top surface 81a. The intermediate portion is formed into a convex arc-shaped and gradually rising front convex arc-shaped upper surface 86b and a rear convex arc-shaped upper surface 86c that is convex arc-shaped and forms the top, and the rear end portion of the top plate 86 is convex. It is formed on a corner surface 86d that is arc-shaped and rapidly descends, and a convex arc-shaped rear surface 86e that is convex arc-shaped and descends rapidly.

すなわち横押し作用部８５の上部は、前後方向の中間部分が前下方への傾斜状上面８６ａに形成されるとともに、この傾斜状上面８６ａに連ねて前端部分には、前記傾斜状上面８６ａに対して角度の緩やかな始端凹円弧状上面８１ａが形成されることになる。また、始端凹状上面８１ａと傾斜状上面８６ａと前凸円弧状上面８６ｂと後凸円弧状上面８６ｃとコーナー面８６ｄと凸円弧状後面８６ｅとは、前部から後部へと、この順で連続して形成されることになる。この連続形成によって、側面視において全体を曲面化して見栄えの良いものとし得る。   In other words, the upper part of the lateral pushing action portion 85 is formed with an inclined upper surface 86a in the front-rear direction, and the front end portion is connected to the inclined upper surface 86a with respect to the inclined upper surface 86a. As a result, a start-end concave arc-shaped upper surface 81a having a gentle angle is formed. Further, the start-end concave upper surface 81a, the inclined upper surface 86a, the front convex arcuate upper surface 86b, the rear convex arcuate upper surface 86c, the corner surface 86d, and the convex arcuate rear surface 86e continue in this order from the front to the rear. Will be formed. By this continuous formation, the whole surface can be curved and look good.

また天板材８６の後端部分を凸円弧状のコーナー面８６ｄとすることで、たとえば転換設備の前後に搬入用や搬出用の搬送手段（ベルトコンベア装置などで図示せず。）が配設されていたときで、誤動作などによって反転中の物品横押し体８０がベルトなどに接触しようとしたとき、コーナー面８６ｄが接触することでベルトなどの損傷を防止し得る。   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.

そして天板材８６の上面で、前端部８１Ａと天板材８６との境界部分、ならびに前記左右方向リブ板材８７の上方位置には、凹部８９が左右方向の全長に亘って形成されている。したがって、たとえば横押し作用部８０を樹脂成形した際に、左右方向リブ板材８７群の部分に全長に亘って生じる凹部８９群を有効に利用して、デザイン性を向上し得る。   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.

また、上板材８１の前端部８１Ａと天板材８６（横押し作用部８５）とを平面視（側面形状）したとき、前端部８１Ａの左右角部は凸円弧状の円弧状側面８１ｂに形成されるとともに、その後端に連続して凹円弧状でかつ急激に入り込む凹円弧状側面８１ｃが形成されている。そして天板材８６の両側面は、凹円弧状側面８１ｃに連なる前端部が幅広でかつ幅が次第に絞られて幅狭の後端部となるように、すなわち起立状でかつ前部に対して後部が他側面側へと傾斜した横向き傾斜面８６ｆに形成されている。これにより天板材８６は、平面視において傾斜角度θが２０度の台形板状に形成され、そして、上板材８１の前端部８１Ａを除いた部分やリブ板材８７，８８群は台形板状内に納まるように形成されている。   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 20 degrees in a 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 within the trapezoidal plate shape. It is formed to fit.

前記横向き傾斜面８６ｆの部分には、その横押し当接面９０ａが平面視において凹凸状でかつゴム板などからなる横押し当接部材９０が着脱自在に取り付けられている。すなわち横押し当接部材９０は、横押し作用部８５から上板材８１に亘っての側面を覆う形状、つまり上面は横押し作用部８５の上面に連なる形状とされている。また取り付け状態においては、前端部分が凹円弧状側面８１ｃに当接され、その凹凸状の横押し当接面９０ａにおける凸状側面部（外側面）が前記円弧状側面８１ｂの後端に連なる厚さとして形成されている。   A laterally pressing contact member 90 made of a rubber plate or the like is detachably attached to the portion of the laterally inclined surface 86f. That is, the lateral pressing contact member 90 has a shape that covers the side surface extending from the lateral pressing operation portion 85 to the upper plate member 81, that is, a top surface that is continuous with the upper surface of the lateral pressing operation portion 85. In the mounted state, the front end portion is in contact with the concave arcuate side surface 81c, and the convex side surface portion (outer side surface) of the concave / convex lateral pressing contact surface 90a is connected to the rear end of the arcuate side surface 81b. It is formed as Sasa.

さらに横押し当接部材９０の後端部分９０Ａは、横押し作用部８５の後端、すなわちコーナー面８６ｄや凸円弧状後面８６ｅからなる後端８５Ａに対して、設定長さＬだけ後方へ突出されている。その際に設定長さＬは、前に位置される物品横押し体８０に設けられた横押し当接部材９０の後端（後端面）９０Ｂと、後に位置される物品横押し体８０に設けられた横押し当接部材９０の前端（前端面）９０Ｃとの間に、隙間Ｓが生じるように設定されている。ここで横押し当接部材９０はゴム板からなることで、その後端部分９０Ａは、左右方向に弾性変形自在に形成されることになる。   Further, the rear end portion 90A of the lateral pressing contact member 90 projects rearward by a set length L with respect to the rear end of the lateral pressing operation portion 85, that is, the rear end 85A formed of the corner surface 86d and the convex arcuate rear surface 86e. Has been. At this time, the set length L is provided on the rear end (rear end surface) 90B of the lateral pressing contact member 90 provided on the article lateral pressing body 80 positioned in front and on the article lateral pressing body 80 positioned rearward. The gap S is set so as to be formed between the front end (front end surface) 90 </ b> C of the lateral pressing contact member 90. Here, the laterally pressing contact member 90 is made of a rubber plate, and the rear end portion 90A is formed to be elastically deformable in the left-right direction.

そして横押し当接部材９０の内側面側で前後３箇所（前後複数箇所）からは、横押し作用部８５の空洞部に差し込み自在なそれぞれ変形筒状の突出部９１が一体形成され、これら突出部９１の扁平状の下面からは係止部９２が下向きで突出形成されている。なお上板材８１には、係止部９２群が係合自在な係合孔部９３群が形成されている。ここで係合孔部９３は、左右方向リブ板材８７を避ける状態で、左側の前後３箇所（前後複数箇所）と右側の前後３箇所（前後複数箇所）とに形成されているが、その際に左列の係合孔部９３群と右列の係合孔部９３群とは前後方向で互い違い状（位置ずれ状）として形成されている。   Then, from the three front and rear positions (a plurality of front and rear positions) on the inner surface side of the lateral pressing contact member 90, deformed cylindrical projecting portions 91 that can be inserted into the hollow portion of the lateral pressing action portion 85 are integrally formed. A locking portion 92 is formed so as to protrude downward from the flat bottom surface of the portion 91. The upper plate member 81 is formed with an engaging hole portion 93 group that can engage with the engaging portion 92 group. Here, the engagement hole portion 93 is formed in the left and right front and rear three places (a plurality of front and rear places) and the right front and rear three places (a plurality of front and rear places) while avoiding the left and right direction rib plate material 87. Further, the engagement hole 93 group in the left row and the engagement hole portion 93 group in the right row are formed in a staggered form (position shift form) in the front-rear direction.

したがって横押し当接部材９０は、横押し作用部８５の空洞部に突出部９１を差し込み、係止部９２群を係合孔部９３群に係合させることで、その内側面を横向き傾斜面８６ｆに当接させ、横押し当接面９０ａの凸状側面部を円弧状側面８１ｂの後端に連なる状態とし、かつ横押し当接面９０ａを前部に対して後部が他側面側へと、２０度の傾斜角度θに傾斜させた状態で、横押し作用部８５に着脱自在に取り付け得る。その際に係止部９２群の係合孔部９３群への係合によって、横押し当接部材９０の取り付けを強固に行えるとともに、左列と右列とを前後方向で互い違い状としたことによって、横押し当接部材９０の樹脂成形による形勢を容易に行えることになる。以上の８６〜９３などによって横押し作用部８５の一例が構成される。   Therefore, the laterally pressing contact member 90 is inserted into the hollow portion of the laterally pushing action portion 85 and the engaging portion 92 group is engaged with the engaging hole portion 93 group so that the inner side surface thereof is inclined horizontally. 86f, the convex side surface of the laterally pressing contact surface 90a is connected to the rear end of the arcuate side surface 81b, and the laterally pressing contact surface 90a is directed to the other side with respect to the front side. , And can be detachably attached to the lateral pushing action portion 85 in a state of being inclined at an inclination angle θ of 20 degrees. At that time, by engaging the engaging portion 92 group with the engaging hole portion 93 group, the lateral pressing contact member 90 can be firmly attached, and the left and right rows are staggered in the front-rear direction. Thus, the lateral pressing contact member 90 can be easily formed by resin molding. An example of the lateral pushing action portion 85 is configured by the above 86-93 and the like.

前記底板材８４の上面側には、両脚板部５５，５６間に嵌合される上向き突状の被嵌合部９５が連設され、この被嵌合部９５の上半部は相反する側（外側）へ突出することで厚肉部に形成され、これら厚肉部によって、前記案内部５９，６０に嵌合して摺動案内される被案内部９６，９７が形成されている。すなわち、被案内部９６，９７の上端部で相反する面（外側面）によって、前後案内面５９ａ，６０ａに摺接案内される前後被案内面９６ａ，９７ａが形成されるとともに、下面によって、下位案内面５９ｂ，６０ｂに摺接案内される下位被案内面９６ｂ，９７ｂが形成され、そして厚肉部の上面によって、前記凸状部５３の扁平面５３ａに下方から対向されて摺接案内される上位被案内面９６ｃ，９７ｃが形成されている。これにより前記物品横押し体８０は、前後の被案内部９６，９７を介して、物品支持体５０における案内部５９，６０に嵌合されて案内されるように構成されている。   On the upper surface side of the bottom plate member 84, an upward protruding fitting portion 95 fitted between the leg plate portions 55 and 56 is continuously provided, and the upper half of the fitting portion 95 is on the opposite side. By projecting outward (outside), thick portions are formed, and by these thick portions, guided portions 96 and 97 are formed which are fitted to the guide portions 59 and 60 and are slidably guided. That is, the front and rear guided surfaces 96a and 97a slidably guided to the front and rear guide surfaces 59a and 60a are formed by the opposite surfaces (outer surfaces) at the upper ends of the guided portions 96 and 97, and the lower surfaces are formed by the lower surfaces. Lower guided surfaces 96b and 97b that are slidably guided to the guide surfaces 59b and 60b are formed, and are slidably guided to face the flat surface 53a of the convex portion 53 from below by the upper surface of the thick portion. Upper guided surfaces 96c and 97c are formed. Thus, the article laterally pressing body 80 is configured to be fitted and guided to the guide portions 59 and 60 in the article support body 50 through the front and rear guided portions 96 and 97.

ここで平面視（上面形状）において、物品横押し体８０の上板材８１や横押し作用部８５の天板材８６は、前述したように、前端部が幅広でかつ幅が次第に絞られて後端部が幅狭の台形板状に形成され、そして前板材８２は、円弧状側面８１ｂによる絞りによって上板材８１の前端部よりも少し幅の狭い幅広の矩形板状に形成され、後板材８３は、上板材８１の幅狭後端部に連なる幅狭上半部８３Ａと、次第に拡幅されて前板材８２における少し幅の狭い幅広と同様の幅となる台形状下半部８３Ｂとにより逆Ｔ字型状に形成され、底板材８４は、前板材８２と後板材８３との下端に連なる幅広の正方形に近い矩形板状に形成されている。すなわち、台形板状の上板材８１や天板材８６に対して、矩形板状の底板材８４が長さ方向５１の両側で突出される形状となり、これにより、前位円弧部５７Ａの下向き円弧面５７ａや後位円弧部５８Ａの下向き円弧面５８ａに対する対向幅を広くできる。   Here, in plan view (top surface shape), as described above, the top plate member 81 of the article lateral pusher 80 and the top plate member 86 of the lateral push action portion 85 have a wide front end and a gradually narrowed rear end. The front plate member 82 is formed in a wide rectangular plate shape that is slightly narrower than the front end portion of the upper plate member 81 by the restriction by the arc-shaped side surface 81b. The narrow upper half 83A connected to the narrow rear end of the upper plate 81 and the trapezoid lower half 83B that is gradually widened and has the same width as the slightly narrower width of the front plate 82 are inverted T-shaped. The bottom plate member 84 is formed in a mold shape, and is formed in a rectangular plate shape close to a wide square connected to the lower ends of the front plate member 82 and the rear plate member 83. That is, the bottom plate member 84 having a rectangular plate shape protrudes on both sides in the length direction 51 with respect to the upper plate member 81 and the top plate member 86 in a trapezoid plate shape, and thereby the downward arc surface of the front arc portion 57A. 57a and the rear arcuate portion 58A can be widened against the downward arcuate surface 58a.

そして、前記被嵌合部９５は平面視において長さ方向５１に長い長方形状であって、前部の被案内部９６は底板材８４と同様の幅に設定されており、また後部の被案内部９７は底板材８４の幅に対して幅広とし、これにより突出される部分によって被ストッパー部９９を形成している。その際に被ストッパー部９９が、サイドブラケット６１における本体部６２の内側面に当接されることで、長さ方向５１の移動限が規制されるように構成されている。なお、被ストッパー部９９の当接面は直線状となっているが、これは外方凸の凸状円弧面であってもよい。   The fitted portion 95 has a rectangular shape that is long in the longitudinal direction 51 in plan view, the front guided portion 96 is set to have the same width as the bottom plate 84, and the rear guided portion. The portion 97 is wider than the width of the bottom plate member 84, and a portion to be stopped 99 is formed by a portion protruding thereby. At that time, the stopper 99 is brought into contact with the inner surface of the main body 62 in the side bracket 61 so that the movement limit in the length direction 51 is restricted. In addition, although the contact surface of the to-be-stopped part 99 is linear, this may be an outwardly convex convex arc surface.

前記物品横押し体８０の被案内部９６，９７側には、物品支持体５０における物品載置板部５４に下方から当接自在な上向き弾性体と、前部の脚板部５５に内側から当接自在な前向き弾性体とが設けられている。すなわち、被嵌合部９５における長さ方向５１の両端部分で両被案内部９６，９７の間には、主搬送経路４５の方向で一対のスリット１００を介して上向き舌片体（上向き弾性体の一例）１０１が形成され、これら上向き舌片体１０１は上下方向に弾性変形可能に構成されている。両上向き舌片体１０１の遊端には上方への当接部１０１ａが形成され、この当接部１０１ａが被嵌合部９５の上面よりも上方へ突出して形成されることによって、物品載置板部５４に下方から弾性的に当接自在に構成されている。   On the guided parts 96 and 97 side of the article laterally pressing body 80, an upward elastic body that can contact the article mounting plate part 54 of the article support body 50 from below and a front leg plate part 55 are contacted from the inside. A forward-facing elastic body that can be freely contacted is provided. That is, an upward tongue piece (upward elastic body) is interposed between the guided portions 96 and 97 at both ends of the fitted portion 95 in the length direction 51 via the pair of slits 100 in the direction of the main transport path 45. An example) 101 is formed, and these upward tongue pieces 101 are configured to be elastically deformable in the vertical direction. An upper contact portion 101a is formed at the free ends of both upward tongue pieces 101, and the contact portion 101a is formed so as to protrude upward from the upper surface of the fitted portion 95. The plate portion 54 is configured to be elastically contactable from below.

また、前部の被案内部９６における長さ方向５１の両端部分には、上下方向で一対のスリット１０２を介して前向き舌片体（前向き弾性体の一例）１０３が形成され、これら前向き舌片体１０３は前後方向に弾性変形可能に構成されている。両前向き舌片体１０３の遊端には前方への当接部１０３ａが形成され、この当接部１０３ａが前後被案内面９６ａよりも前方へ突出して形成されることによって、前部の脚板部５５に内側から弾性的に当接自在に構成されている。   Further, a forward tongue piece (an example of a forward elastic body) 103 is formed on both ends of the front guided portion 96 in the length direction 51 via a pair of slits 102 in the vertical direction. The body 103 is configured to be elastically deformable in the front-rear direction. A front abutting portion 103a is formed at the free ends of the two forward tongue pieces 103, and the abutting portion 103a is formed to protrude forward from the front and rear guided surfaces 96a, whereby the front leg plate portion is formed. 55 is configured to be elastically contactable from the inside.

上記構成の物品横押し体８０において、上板材８１と前板材８２と後板材８３とは、一部の板厚を不均一として形成されている。すなわち、前板材８２ならびに後板材８３は、上板材８１に対して下方に延びるにつれて、相対向側（中心側）に向かって板厚が次第に厚くなるように形成されている。   In the article laterally pressing body 80 having the above-described configuration, the upper plate member 81, the front plate member 82, and the rear plate member 83 are formed so that a part of the plate thickness is not uniform. That is, the front plate member 82 and the rear plate member 83 are formed so that the plate thickness gradually increases toward the opposite side (center side) as it extends downward with respect to the upper plate member 81.

つまり、前述したように物品支持体５０の前板部５７と後板部５８とが、物品載置板部５４に対して下方に延びるにつれて互いに接近するように内側傾斜状（内側絞り状）であることから、それによって生じたスペースを利用して、前板材８２ならびに後板材８３の上端部分の厚さｔに対して、下端部分の厚さＴ１が厚く形成されている。そして底板材８４の厚さＴ２は、前板材８２と後板材８３の下端部分の厚さＴ１に連続されて厚く形成されるとともに、前板材８２と後板材８３との下端に連続する部分から中央部分に延びるにつれて、空所８４Ａを挟んで実質の板厚Ｔ３が次第に厚くなるように形成されている。つまり［ｔ＜Ｔ１≒Ｔ２＜Ｔ３］に形成されている。このような厚さの変化により、物品横押し体８０の前後長さを長く（大型化）することなく、この物品横押し体８０の全体の強度アップを図っている。 That is, as described above, the front plate portion 57 and the rear plate portion 58 of the article support 50 are inclined inward (inner diaphragm shape) so as to approach each other as they extend downward with respect to the article placement plate section 54. since there, by use of the space caused by it, before the thickness t of the upper end portion of the plate member 82 and rear plate 83, the thickness T 1 of the lower end portion is formed thick. The thickness T 2 of the bottom plate member 84 is formed to be continuous with the thickness T 1 of the lower end portions of the front plate member 82 and the rear plate member 83 and is formed to be continuous with the lower ends of the front plate member 82 and the rear plate member 83. as from extending to the central portion, is substantially the thickness T 3 across the cavity 84A is formed to be gradually thicker. That is, it is formed as [t <T 1 ≈T 2 <T 3 ]. Due to such a change in thickness, the overall strength of the article lateral pressing body 80 is increased without increasing (increasing) the longitudinal length of the article lateral pressing body 80.

その際に底板材８４は、中央部が扁平な厚肉部でかつ周辺が前後端および左右端から次第に厚くなる傾斜部に形成されているが、その下面８４ａは全体としてフラット状に形成されており、これにより他物との引っ掛かりを無くし得る。さらに、前記物品横押し体８０における上板材８１側の下面には、前記物品支持体５０の物品載置板部５４に形成した凸状部５２に上方から対向される３本の凹溝部１０４が形成されている。以上の８１〜１０４などにより物品横押し体８０の一例が構成される。かかる物品横押し体８０は、横押し当接部材９０を除いて合成樹脂によって一体成形されている。   At that time, the bottom plate 84 is formed in a thick portion with a flat central portion and an inclined portion where the periphery gradually increases from the front and rear ends and the left and right ends, but the lower surface 84a is formed in a flat shape as a whole. Thus, it is possible to eliminate the catch with other objects. Furthermore, on the lower surface of the article laterally pressing body 80 on the upper plate member 81 side, there are three concave groove portions 104 facing the convex portion 52 formed on the article mounting plate portion 54 of the article support 50 from above. Is formed. An example of the article laterally pressing body 80 is configured by the above 81 to 104 and the like. The article laterally pressing body 80 is integrally formed of synthetic resin except for the laterally pressing contact member 90.

前記物品横押し体８０の下部側には、前記被嵌合部９５を利用して被案内体が取り付けられる。すなわち前記被嵌合部９５の中央部、すなわち被案内部９６，９７間の中央部からローラ軸（支持軸の一例）１０７が、その上部を埋め込み成形により支持させることで垂設され、このローラ軸１０７の突出下部に、案内ローラ（被案内体の一例）１０８が遊転自在に取り付けられ、以て案内ローラ１０８は物品横押し体８０の裏面外方に位置される。このようにローラ軸１０７の上部を被案内部９６，９７間の中央部に埋め込み成形により支持させることで、このローラ軸１０７の支持部を両脚板部５５，５６間に位置し得、すなわち物品支持体５０の下端である円弧部５７Ａ，５８Ａよりも上方に位置し得、これにより案内ローラ１０８を円弧部５７Ａ，５８Ａに接近して配置できて、物品横押し体８０自体の高さを低くし得る。さらにローラ軸１０７は、十分に高さを取れる被案内部９６，９７間において強固に支持し得る。   A guided body is attached to the lower side of the article laterally pressing body 80 using the fitted portion 95. That is, a roller shaft (an example of a support shaft) 107 is suspended from a central portion of the fitted portion 95, that is, a central portion between the guided portions 96 and 97 by supporting an upper portion thereof by embedding molding. A guide roller (an example of a guided body) 108 is attached to the projecting lower portion of the shaft 107 so as to be freely rotatable, and thus the guide roller 108 is positioned outside the back surface of the article laterally pressing body 80. Thus, by supporting the upper portion of the roller shaft 107 by embedding molding in the central portion between the guided portions 96 and 97, the support portion of the roller shaft 107 can be positioned between the leg plate portions 55 and 56, that is, the article. It can be located above the arc portions 57A and 58A, which are the lower ends of the support body 50, whereby the guide roller 108 can be arranged close to the arc portions 57A and 58A, and the height of the article laterally pressing body 80 itself can be lowered. Can do. Further, the roller shaft 107 can be firmly supported between the guided portions 96 and 97 which can take a sufficient height.

It is attached.

図７〜図９に示すように、前記上位フレーム材１０（本体フレーム１の上部）で、無端チェーン４０を配設するとともに往路側案内レール部１８を形成してなる部分に、無端チェーン４０や回転体７０の上方を閉塞状とするためのカバー体（チェーンカバー）１４０が配置される。図２、図９に示すように、本体フレーム１の両側外方には、主搬送経路４５に対して外方かつ下手側へと傾斜した分岐搬送経路１４５Ａ，１４５Ｂを形成する分岐コンベヤ１４６Ａ，１４６Ｂが設けられる。１５０は物品を示す。   As shown in FIGS. 7 to 9, in the upper frame material 10 (upper part of the main body frame 1), the endless chain 40 or the endless chain 40 is formed on the portion formed with the forward-side guide rail portion 18. A cover body (chain cover) 140 for closing the rotating body 70 is disposed. As shown in FIGS. 2 and 9, branch conveyors 146 </ b> A and 146 </ b> B that form branch transport paths 145 </ b> A and 145 </ b> B that are inclined outward and inferior to the main transport path 45 on both outer sides of the main body frame 1. Is provided. Reference numeral 150 denotes an article.

以下に、上記した実施の形態１において、物品１５０の搬送、分岐作用を説明する。
すなわち、駆動装置３４の電動機３５を作動させ、減速機３６に連動した駆動軸３１を介してスプロケット３９を強制回転させることで、両無端チェーン４０を移動し得る。この両無端チェーン４０の移動によって物品支持体５０群を、回転体７０を介して両案内レール部１８，２６の上向き支持面１８ａ，２６ａに支持案内させるとともに、サイドローラ７１を介して両案内レール部１８や上端延長部２９の横向き案内面１８ｂ，２９ａに案内させることで、安定した状態で移動し得る。その際に復路側においては、回転体７０の上方に上端延長部２９が位置することで、この回転体７０の浮き上りを阻止し得、以て物品支持体５０群を上下でガタつくことなく安定した状態で移動し得る。これにより物品支持体５０群が循環移動することから、始端部の物品支持体５０群上に供給した物品１５０を主搬送経路４５上で搬送し得る。 Hereinafter, in the first embodiment described above, the conveyance and branching operations of the article 150 will be described.
That is, both endless chains 40 can be moved by operating the electric motor 35 of the drive device 34 and forcibly rotating the sprocket 39 via the drive shaft 31 interlocked with the speed reducer 36. 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 both guide rail portions 18 and 26 via the rotating body 70, and to both guide rails via the side rollers 71. By being guided by the lateral guide surfaces 18b and 29a of the part 18 and the upper end extension part 29, it can move in a stable state. At that time, the upper end extension 29 is positioned above the rotating body 70 on the return path side, so that the rotating body 70 can be prevented from rising, and thus the article support 50 group does not rattle up and down. Can move in a stable state. As a result, the article support 50 group circulates and moves, so that the article 150 supplied onto the article support 50 group at the start end can be conveyed on the main conveyance path 45.

なお搬送時において、往路での両無端チェーン４０の移動は、カバー体１４０の下方でかつ潤滑油受け部１３の上方で行われ、また復路での両無端チェーン４０の移動は、上端延長部２９の下方でかつ潤滑油受け部２５の上方で行われる。   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.

このような搬送を行う際に、物品支持体５０群と一体的に移動する物品横押し体８０は、その案内ローラ１０８が案内装置１１０，１１６群に案内されることによって、被案内部９６を介して物品支持体５０の長さ方向５１に往復移動したり、物品支持体５０とともに主搬送経路４５に沿って直線状に移動したりする。   During such conveyance, the article laterally pressing body 80 that moves integrally with the article support 50 group is guided by the guide rollers 108 to the guide devices 110 and 116, thereby moving the guided portion 96. 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.

すなわち、たとえば一方側（左側）の始端案内部１１１Ａに案内されている案内ローラ１０８は、振り分け手段１３２Ａが直線状振り分け姿勢のときに直進案内され、そして案内作用を受けない状態で直進したのち終端案内部１１４Ａに案内されることになる。これにより物品横押し体８０は物品１５０に作用せず、この物品１５０は主搬送経路４５上を直進状に搬送される。なお反対側（右側）も同様であって、始端案内部１１１Ｂの案内ローラ１０８は、振り分け手段１３２Ｂから終端案内部１１４Ｂへと移動することになる。   That is, for example, the guide roller 108 guided by the one-side (left-side) start-end guide portion 111A is guided in a straight line when the sorting unit 132A is in the linear sorting position, and after straight running in a state in which it does not receive a guiding action, it 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 150, and the article 150 is conveyed in a straight line on the main conveyance path 45. The same applies to the opposite side (right side), and the guide roller 108 of the start end guide portion 111B moves from the sorting means 132B to the end guide portion 114B.

また、一方側の始端案内部１１１Ａに案内されている案内ローラ１０８は、振り分け手段１３２Ａが傾斜状振り分け姿勢のときに内側へ傾斜案内され、そして内移動案内部１１２Ａに案内されて内側へ移動されたのち、上部切り換え手段１３０を介して外移動案内部１１３Ｂに移り、この外移動案内部１１３Ｂに案内されて外側へ移動されたのち終端案内部１１４Ｂに案内される。これにより物品横押し体８０群は、搬送方向に移動しながら主搬送経路４５を横切ることになり、以て他側の横押し作用部８５が物品１５０に横押し作用して、この物品１５０を、その向きを変えながら、主搬送経路４５に対して傾斜状で分岐移動させ、他方の分岐コンベヤ１４６Ｂに渡すことになる。   Further, the guide roller 108 guided to the one-side starting end guide portion 111A is tilted inward when the distribution means 132A is in the inclined distribution posture, and is guided inward by the inward movement guide portion 112A and moved inward. After that, it moves to the outer movement guide part 113B via the upper switching means 130, and is guided by 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 pressing bodies 80 crosses the main transport path 45 while moving in the transporting direction, so that the laterally pressing action portion 85 on the other side laterally acts on the article 150, causing the article 150 to move. While changing its direction, it is branched and moved with respect to the main transport path 45 and delivered to the other branch conveyor 146B.

なお反対側も同様であって、始端案内部１１１Ｂの案内ローラ１０８は、振り分け手段１３２Ｂ、内移動案内部１１２Ｂ、上部切り換え手段１３０、外移動案内部１１３Ａ、終端案内部１１４Ａと案内され、物品横押し体８０群の一側の横押し作用部８５が、横押し当接部材９０を介して物品１５０に横押し作用して、この物品１５０を一方の分岐コンベヤ１４６Ａに渡すことになる。   The opposite side is the same, and the guide roller 108 of the start end guide portion 111B is guided by the sorting means 132B, the inner movement guide portion 112B, the upper switching means 130, 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 150 via the transverse pushing abutting member 90, and the article 150 is delivered to one branch conveyor 146A.

上述したようにして終端案内部１１４Ａ，１１４Ｂの端部に達した案内ローラ１０８は反転案内体１３６Ａ，１３６Ｂに案内されて反転する。そして復路案内装置１１６においては、まず内移動案内部１１７Ａ，１１７Ｂに案内されて中央部に移動され、次いで下部切り換え手段１３１により左右に振り分けられたのち、外移動案内部１１８Ａ，１１８Ｂの案内により外側へと移動される。その後に、反転案内体１３５Ａ，１３５Ｂに案内されて反転したのち、始端案内部１１１Ａ，１１１Ｂのいずれかに移される。   As described above, the guide roller 108 that has reached the end portions of the end guide portions 114A and 114B is guided by the reverse guide bodies 136A and 136B to be reversed. In the return route guidance device 116, first, it is guided by 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 131, and then is guided to the outside 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 135A and 135B, it is moved to one of the start end guide portions 111A and 111B.

このような反転のとき、前後のサイドブラケット６１間が相対的に伸縮される状態になり、これにより嵌合部６６とリング体７５とが摺接動するが、その際に鉄製の嵌合部６６と樹脂製のリング体７５との摺接動、つまり嵌合面が異なる材質からなる摺接動であることから、たとえば嵌合面が同じ材質からなる摺接動に比べて、摩耗や騒音の発生を減少し得る。   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.

前述したように物品横押し体８０を移動させる際に、物品横押し体８０が横押し移動を行わず無負荷状態のとき、または軽い物品１５０を横押し移動させる軽負荷状態のときには、両上向き舌片体１０１の当接部１０１ａが凸状部５３の扁平面５３ａに下方から当接し、その弾性反発力による押し下げ力によって下位被案内面９６ｂ，９７ｂを下位案内面５９ｂ，６０ｂに押し付けるとともに、両前向き舌片体１０３の当接部１０３ａが案内部５９の前後案内面５９ａに内側から当接し、その弾性反発力による後押し力によって前後被案内面９７ａを案内部６０の前後案内面６０ａに押し付けることになる。   As described above, when the article lateral pusher 80 is moved, when the article lateral pusher 80 does not perform lateral push movement and is in a no-load state, or in a light load state in which the light article 150 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 guiding surfaces 59b and 60b by the pressing force due to the elastic repulsive force. The abutting portions 103a of both forward tongue pieces 103 abut on 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 pushing force due to the elastic repulsive force. It will be.

これにより、物品支持体５０の長さ方向５１に対する物品横押し体８０の往復移動は、当接部１０１ａが扁平面５３ａに弾性的に当接して摺接し、下位被案内面９６ｂ，９７ｂが下位案内面５９ｂ，６０ｂに当接して摺接し、当接部１０３ａが前後案内面５９ａに弾性的に当接して摺接し、前後被案内面９７ａが前後案内面６０ａに当接して摺接する状態で行える。   Thereby, in the reciprocating movement of the article laterally pressing body 80 in the longitudinal direction 51 of the article support body 50, the contact portion 101a elastically contacts and slides on the flat surface 53a, 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 rear guide surfaces 60a. .

また物品横押し体８０が重い物品１５０の横押し移動を行っている重負荷状態のときには、その横押し偏荷重によって物品支持体５０に対して物品横押し体８０が少し変位することになる。すなわち、物品１５０への当接側においては、上向き舌片体１０１の弾性力に抗して被案内部９６，９７が上昇して上位被案内面９６ｃ，９７ｃが凸状部５３の扁平面５３ａに下方から当接し、また物品１５０への当接側とは反対側においては、前向き舌片体１０３の弾性力に抗して前後被案内面９６ａが前後案内面５９ａに内側から当接することになる。   Further, when the article lateral pusher 80 is in a heavy load state in which the heavy article 150 is laterally pushed, the article lateral pusher 80 is slightly displaced with respect to the article support 50 by the lateral push offset load. That is, on the contact side with the article 150, 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 150. Become.

これにより、物品支持体５０の長さ方向５１に対する物品横押し体８０の往復移動は、上位被案内面９６ｃ，９７ｃや当接部１０１ａが扁平面５３ａに当接して摺接し、下位被案内面９６ｂ，９７ｂが下位案内面５９ｂ，６０ｂに当接して摺接し、前後被案内面９６ａや当接部１０３ａが前後案内面５９ａに当接して摺接し、前後被案内面９７ａが前後案内面６０ａに当接して摺接する状態で行える。   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 make sliding contact, the front and rear guided surfaces 96a and the contact portion 103a are in contact with and slide in 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.

これらにより前記物品横押し体８０の往復移動は、前後の被案内部９６，９７を介して、物品支持体５０における案内部５９，６０に嵌合されて案内される状態で、すなわち、好適な摺接摩擦が生じた状態で、ガタつきがなく、かつ姿勢（向き）を大きく変化させることなく、常に安定して行える。さらに、舌片体１０１，１０３群を長さ方向５１の両端に振り分けて形成していることで、物品横押し体８０の移動は、往復のいずれにおいても同等状の好適な摺接摩擦が生じた状態で行える。   Accordingly, the reciprocating movement of the article laterally pressing body 80 is performed in a state in which it is guided by being fitted to the guide portions 59 and 60 of the article support body 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.

また、物品載置板部５４の下面に下向きの凸状部５３を形成するとともに、この凸状部５３の下部を扁平面５３ａに形成し、そして被案内部９６，９７の上面を、扁平面５３ａに下方から対向する上位被案内面９６ｃ，９７ｃに形成していることで、物品横押し体８０群の長さ方向５１への移動時には、上位被案内面９６ｃ，９７ｃが扁平面５３ａ上を摺動することから、その移動は摩擦抵抗が少ない状態で行え、以て物品横押し体８０を傷つけることなく、しかも物品支持体５０側を摩耗させることなく、所期の移動をスムースに行える。   Further, 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 53a from below, 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.

上述したように、物品横押し体８０群が搬送方向に移動しながら主搬送経路４５を横切ることによって、横押し作用部８５を物品１５０に横押し作用させて、この物品１５０を分岐移動させ、分岐コンベヤ１４６Ａ，１４６Ｂに渡しているが、その際に物品１５０は、凸状部５２群の扁平面５２ａ間で支持され、かつ扁平面５２ａ上を摺動することから、その分岐移動は摩擦抵抗が少ない状態で行え、以て物品１５０を傷つけることなく、しかも物品支持体５０側を摩耗させることなく、所期の分岐移動をスムースに行える。   As described above, when the article laterally pressing body 80 group moves in the transporting direction and crosses the main transport path 45, the laterally pushing action portion 85 is laterally pushed to the article 150, and the article 150 is branched and moved. At this time, the article 150 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 150 and without wearing the article support 50 side.

そして横押し作用部８５の側部は、前端部８１Ａの左右角部が円弧状側面８１ｂに形成され、この円弧状側面８１ｂの後端に横押し当接面９０ａが連なる状態で横押し当接部材９０が設けられるとともに、横押し当接部材９０の後端部分９０Ａが横押し作用部８５の後端８５Ａに対して設定長さＬだけ後方へ突出されていることから、この横押し当接部材９０による横押し作用面（押し面）を大きく（長く）し得、以て安定した横押し移動を可能にし得るとともに、前後の物品横押し体８０における横押し当接部材９０間の隙間Ｓ（図１１参照）を小さくして、物品１５０を挟み込みし難い状態で所期の横押し移動を可能にし得る。また何らかの事情で、前後の物品横押し体８０間で物品１５０を挟み込むような状態になったとき、ゴム板からなる横押し当接部材９０の後端部分９０Ａが左右方向に弾性変形して（撓んで）逃げることになり、これにより物品横押し体８０や物品１５０が破損することを防止し得る。   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 and the rear end portion 90A of the side press contact member 90 protrudes rearward by the set length L with respect to the rear end 85A of the side press action portion 85, this side press contact The side pushing action surface (pushing surface) by the member 90 can be made larger (longer), so that stable side pushing movement can be achieved, and the gap S between the side pushing contact members 90 in the front and rear article pushing bodies 80 can be made. (Refer to FIG. 11) can be made small, and the desired lateral movement can be made possible in a state in which the article 150 is hardly sandwiched. For some reason, when the article 150 is sandwiched between the front and rear article laterally pressing bodies 80, the rear end portion 90A of the laterally pressing contact member 90 made of a rubber plate is elastically deformed in the left-right direction ( It is possible to prevent the article side pushing body 80 and the article 150 from being damaged.

さらに横押し作用部８５の上部は、前後方向の中間部分が前下方への傾斜状上面８６ａに形成されるとともに、この傾斜状上面８６ａに連ねて前端部分には、前記傾斜状上面８６ａに対して角度の緩やかな始端凹状上面８１ａが形成されていることで、たとえば横押し開始時において、前後の物品横押し体８０間で物品１５０を挟み込むような状態になったとき、この物品１５０の下に、まず角度の緩やかな始端凹状上面８１ａがスムースに潜り込み、そして物品１５０を傾斜状上面８６ａによって持ち上げる状態になる。これにより、挟み込みのない状態で所期の横押し移動を可能にし得、以て物品１５０や物品横押し体８０の破損を防止し得る。なお、前端部８１Ａの左右角部が円弧状側面８１ｂに形成されていることで、物品１５０の下への潜り込みは、よりスムースに行えることになる。   Further, an upper portion of the lateral pushing action portion 85 is formed with an inclined upper surface 86a in the front-rear direction, and the front end portion is connected to the inclined upper surface 86a with respect to the inclined upper surface 86a. By forming the concave upper end surface 81a with a gentle angle, for example, when the article 150 is sandwiched between the front and rear article laterally pressing bodies 80 at the start of the lateral pushing, First, the concave upper surface 81a having a gentle angle enters the smooth state, and the article 150 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 150 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 entry into the bottom of the article 150 can be performed more smoothly.

上述したように、物品横押し体８０群が搬送方向に移動しながら主搬送経路４５を横切ることによって、横押し作用部８５を物品１５０に横押し作用させて、この物品１５０を分岐移動させ、分岐コンベヤ１４６Ａ，１４６Ｂに振り分けて渡しているが、このとき物品支持体５０上の物品１５０は、無端チェーン４０の上方を閉塞状とするために上位フレーム材１０に固定したカバー体１４０の上方を乗り越えることで、物品１５０に付着していた塵埃などが無端チェーン４０側に落下するのを防止し得る。   As described above, when the article laterally pressing body 80 group moves in the transporting direction and crosses the main transport path 45, the laterally pushing action portion 85 is laterally pushed to the article 150, and the article 150 is branched and moved. At this time, the article 150 on the article support 50 is placed above the cover body 140 fixed to the upper frame member 10 so as to close the endless chain 40. By climbing over, it is possible to prevent dust or the like adhering to the article 150 from falling to the endless chain 40 side.

以下に、本発明の実施の形態２を図１５に基づいて説明する。
