以下に、上記した実施の形態１において、転換設備の組み立て、ならびに物品１６０の搬送、分岐作用を説明する。
転換設備の施工時などにおいて、本体フレーム１を枠組み状に組み立て、そして本体フレーム１に無端チェーン４０や物品支持体５０などを組み込んだのち、両上位フレーム材１０の上端にカバー体１４０を配設させる。
Hereinafter, in the first embodiment described above, the assembly of the conversion equipment, the conveyance of the article 160, and the branching action will be described.
When constructing the conversion equipment, the main body frame 1 is assembled into a frame shape, and the endless chain 40 and the article support 50 are assembled into the main body frame 1, and then the cover body 140 is disposed on the upper ends of both upper frame materials 10. Let
すなわち、物品支持体５０に形成した前後一対の空間部にサイドブラケット６１の一対の差し込み部６３を差し込んで、物品支持体５０の端面側にサイドブラケット６１の内面側を当接させたのち、貫通孔６４に外側から通したボルト体６９を螺合部５５Ａ，５５Ｂのいずれかに螺合結合させる。これにより、物品支持体５０の両端にサイドブラケット６１を取り付け得、その際に、両サイドブラケット６１を取り付ける前、または一方のサイドブラケット６１を取り付けた後に、物品支持体５０に対して物品横押し体７５を外嵌させている。
That is, the pair of insertion portions 63 of the side bracket 61 are inserted into the pair of front and rear space portions formed in the article support 50, and the inner surface side of the side bracket 61 is brought into contact with the end face side of the article support 50. A bolt body 69 passed from the outside through the hole 64 is screwed and coupled to one of the screwing portions 55A and 55B. As a result, the side brackets 61 can be attached to both ends of the article support 50, and at that time, before the both side brackets 61 are attached or after one of the side brackets 61 is attached, the article is laterally pushed against the article support 50. The body 75 is externally fitted.
さらに、両サイドブラケット６１を取り付ける前、または両サイドブラケット６１を取り付けた後に、これらサイドブラケット６１側に、筒状連結部６７や回転体７０やサイドローラ７１をセットしている。すなわち、筒状体６５内に対して、筒状連結部６７を外側から差し込んで、その鍔部６７Ａを筒状体６５の外端面に当接させて位置決めするとともに、舌片部６７Ｂ群の外向き凸部６７Ｄを環状溝６５Ａに対して弾性係合させることで、筒状体６５に対して連結部６７を内嵌状で連結し得、以てサイドブラケット６１側に筒状連結部６７をセットし得る。そして、筒状体６５に回転体７０を外嵌するとともに、突出片６２Ａに縦軸７２を介してサイドローラ７１を遊転自在に取り付ける。
Furthermore, before attaching both side brackets 61 or after attaching both side brackets 61, the cylindrical connecting portion 67, the rotating body 70, and the side roller 71 are set on the side bracket 61 side. That is, the cylindrical connecting portion 67 is inserted into the cylindrical body 65 from the outside, and the flange portion 67A is positioned in contact with the outer end surface of the cylindrical body 65, and the outside of the tongue piece portion 67B group is positioned. By elastically engaging the direction convex portion 67D with the annular groove 65A, the connecting portion 67 can be connected to the cylindrical body 65 with an internal fit, and thus the cylindrical connecting portion 67 is provided on the side bracket 61 side. Can be set. Then, the rotating body 70 is externally fitted to the cylindrical body 65, and the side roller 71 is attached to the protruding piece 62A via the vertical axis 72 so as to be freely rotatable.
このようにして、物品支持体５０の両端にサイドブラケット６１を取り付けたのち、無端チェーン４０における特定の長尺連結ピン４３を筒状連結部６７に差し込み結合させることで、物品支持体５０の両端を、それぞれサイドブラケット６１を介して無端チェーン４０に連結し得る。すなわち図５に示すように、無端チェーン４０の所定箇所を外側に移動させる（撓ませる）ことで、この所定箇所を起立部１１の上方を通して外側へ移動させ、以て長尺連結ピン４３の突出部分を潤滑油受け部１３の上方に位置させる。
Thus, after attaching the side bracket 61 to the both ends of the article support body 50, the specific long connection pin 43 in the endless chain 40 is inserted into and coupled to the cylindrical connection portion 67, so that both ends of the article support body 50 are connected. Can be coupled to the endless chain 40 via the side brackets 61, respectively. That is, as shown in FIG. 5, by moving a predetermined portion of the endless chain 40 to the outside (bending), the predetermined portion is moved to the outside through the upright portion 11, so that the long connecting pin 43 protrudes. The part is positioned above the lubricating oil receiver 13.
そして、長尺連結ピン４３の突出部分と筒状連結部６７の差し込み孔６８とを相対向させたのち、差し込み孔６８に対して長尺連結ピン４３の突出部分を外側から差し込み、舌片部６７Ｂ群の内向き凸部６７Ｃを外向き凹部４４に対して弾性係合させることで、長尺連結ピン４３をサイドブラケット６１に結合し得る。
And after making the protrusion part of the long connection pin 43 and the insertion hole 68 of the cylindrical connection part 67 oppose each other, the protrusion part of the long connection pin 43 is inserted into the insertion hole 68 from the outside, and the tongue piece part The long connecting pin 43 can be coupled to the side bracket 61 by elastically engaging the inward convex portion 67C of the 67B group with the outward concave portion 44.
これにより、物品支持体５０の両端を、それぞれサイドブラケット６１を介して無端チェーン４０に連結し得る。その際に長尺連結ピン４３の外側から差し込み（連結）は、起立部１１に邪魔されることなく、作業性を良くして容易に迅速に行える。なお、長尺連結ピン４３の外側への抜き出し（連結解除）も、同様にして、起立部１１に邪魔されることなく、作業性を良くして容易に迅速に行える。
Thereby, both ends of the article support 50 can be connected to the endless chain 40 via the side brackets 61 respectively. In this case, the insertion (connection) from the outside of the long connection pin 43 can be easily and quickly performed with improved workability without being disturbed by the standing portion 11. In addition, the outside connection (release of connection) of the long connection pin 43 can be easily and quickly performed with improved workability without being disturbed by the upright portion 11.
このような連結を順次行うことで、左右一対の無端チェーン４０間に多数の物品支持体５０を取り付け得る。その際に、サイドブラケット６１の嵌合部６６は、隣接したサイドブラケット６１における筒状体６５に外嵌されることになる。
By sequentially performing such connection, a large number of article supports 50 can be attached between the pair of left and right endless chains 40. At that time, the fitting portion 66 of the side bracket 61 is externally fitted to the cylindrical body 65 in the adjacent side bracket 61.
次いで、両上位フレーム材１０の上端にカバー体１４０を配設させる。すなわち、下位起立板部１４１Ａを起立部１１に対して外側から当接させ、下位起立板部１４１Ａの下端を受け面１１ａに上方から当接させた状態で、下位起立板部１４１Ａの下端部分に外側から通したボルト体１４５を、外向き溝部１４内に予め位置させたナット体１４６に螺合させることによって、上位フレーム材１０の起立部１１に対して着脱自在に固定し得る。
Next, the cover body 140 is disposed on the upper ends of the upper frame members 10. That is, the lower standing plate portion 141A is brought into contact with the standing portion 11 from the outside, and the lower end of the lower standing plate portion 141A is brought into contact with the receiving surface 11a from above, and the lower standing plate portion 141A is brought into contact with the lower end portion of the lower standing plate portion 141A. The bolt body 145 passed from the outside can be detachably fixed to the upright portion 11 of the upper frame member 10 by screwing the bolt body 145 into the nut body 146 previously positioned in the outward groove portion 14.
その際に、上板部１４２における横板部１４２Ａの最上面１４２ａを、物品載置板部５４の上面５４ａと面一状のレベルでかつ扁平面５２ａよりも僅かに低い位置とし得、また内端傾斜部１４２Ｂの傾斜上面１４２ｂを、物品載置板部５４の上面５４ａに対して下降した低い位置とし得る。そして、かかる位置関係は、下位起立板部１４１Ａの下端を受け面１１ａに上方から当接させていることで、常に一定状で維持し得る。
At that time, the uppermost surface 142a of the horizontal plate portion 142A in the upper plate portion 142 may be at a level that is flush with the upper surface 54a of the article placement plate portion 54 and slightly lower than the flat surface 52a. The inclined upper surface 142b of the end inclined portion 142B can be a lower position that is lowered with respect to the upper surface 54a of the article placing plate portion 54. And this positional relationship can always be maintained constant by abutting the lower end of the lower upright plate portion 141A on the receiving surface 11a from above.
このような、物品支持体５０の取り付けやカバー体１４０の配設を行う前後に、本体フレーム１側に、往路ガイド装置１１０、復路ガイド装置１１６、上部切り換え手段１３０、下部切り換え手段１３１、振り分け手段１３２Ａ，１３２Ｂなどを配設している。これにより転換設備を組み立て得る。
Before and after the attachment of the article support 50 and the cover 140, the forward guide device 110, the backward guide device 116, the upper switching means 130, the lower switching means 131, and the sorting means are provided on the main body frame 1 side. 132A, 132B, etc. are provided. Thereby, the conversion equipment can be assembled.
このように組み立てた転換設備は、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を介して両ガイドレール部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を介して両ガイドレール部１８，２６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１６０を主搬送経路４５上で搬送し得る。
The conversion equipment assembled in this way can move both endless chains 40 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 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. It can move in a stable state by being guided by the lateral guide surfaces 18b and 29a of the portions 18 and 26. 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 160 supplied onto the starting article support 50 group 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７５は、そのガイドローラ１０８がガイド装置群１１０，１１６に案内されることによって、被ガイド部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。
When such conveyance is performed, the article laterally pressing body 75 that moves integrally with the article support 50 group is guided by the guide rollers 108 and 116 to guide the portion 96 to be guided. 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、たとえば一方側の始端ガイド部１１１Ａに案内されているガイドローラ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、そしてガイド作用を受けない状態で直進したのち終端ガイド部１１４Ａに案内されることになる。これにより物品横押し体７５は物品１６０に作用せず、この物品１６０は主搬送経路４５上を直進状に搬送される。なお反対側も同様であって、始端ガイド部１１１Ｂのガイドローラ１０８は、振り分け手段１３２Ｂから終端ガイド部１１４Ｂへと移動することになる。
That is, for example, the guide roller 108 guided to the start guide part 111A on one side is guided in a straight line when the sorting unit 132A is in the linear sorting position, and then advances straight in a state where it does not receive a guide action, and then the end guide part 114A. Will be guided to. As a result, the article laterally pressing body 75 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 moves from the sorting means 132B to the end guide portion 114B.
また、一方側の始端ガイド部１１１Ａに案内されているガイドローラ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、そして内移動ガイド部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を介して外移動ガイド部１１３Ｂに移り、この外移動ガイド部１１３Ｂに案内されて外側へ移動されたのち終端ガイド部１１４Ｂに案内される。これにより物品横押し体７５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、以て横押し作用部８３の他側の横押し当接部材９０が物品１６０に横押し作用して、この物品１６０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１５１Ｂに渡すことになる。
Further, the guide roller 108 guided to the one-side starting end guide portion 111A is inclined and guided inward when the distribution means 132A is in the inclined distribution posture, 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 130, is guided by this outer movement guide part 113B, is moved outward, and is then guided to the terminal guide part 114B. As a result, the group of article laterally pressing bodies 75 crosses the main transport path 45 while moving in the transporting direction, so that the laterally pressing contact member 90 on the other side of the laterally pressing action part 83 acts laterally on the article 160. Then, while changing the direction of the article 160, the article 160 is branched and moved with respect to the main transport path 45, and is delivered to the other branch conveyor 151B.
なお反対側も同様であって、始端ガイド部１１１Ｂのガイドローラ１０８は、振り分け手段１３２Ｂ、内移動ガイド部１１２Ｂ、上部切り換え手段１３０、外移動ガイド部１１３Ａ、終端ガイド部１１４Ａと案内され、物品横押し体７５群の横押し作用部８３が、一側の横押し当接部材９０を介して物品１６０に横押し作用して、この物品１６０を一方の分岐コンベヤ１５１Ａに渡すことになる。
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 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 laterally pushing action portion 83 of the push body 75 group laterally acts on the article 160 via the lateral pushing contact member 90 on one side, and the article 160 is transferred to one branching conveyor 151A.
上述したようにして終端ガイド部１１４Ａ，１１４Ｂの端部に達したガイドローラ１０８は反転ガイド体１３６Ａ，１３６Ｂに案内されて反転する。そして復路ガイド装置１１６においては、まず内移動ガイド部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、外移動ガイド部１１８Ａ，１１８Ｂの案内により外側へと移動される。その後に、反転ガイド体１３５Ａ，１３５Ｂに案内されて反転したのち、始端ガイド部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 reversal guide bodies 136A and 136B to be reversed. The return path guide device 116 is first guided by the inward movement guide portions 117A and 117B and 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７３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７３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 73 are slidably moved. 66 and the resin ring body 73, 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７５を移動させる際に、物品横押し体７５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１６０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ガイド面９６ｂ，９７ｂを下位ガイド面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がガイド部５９の前後ガイド面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ガイド面９７ａをガイド部６０の前後ガイド面６０ａに押し付けることになる。
As described above, when the article lateral pusher 75 is moved, when the article lateral pusher 75 is in the no-load state without performing the lateral push movement or in the 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.
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７５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、下位被ガイド面９６ｂ，９７ｂが下位ガイド面５９ｂ，６０ｂに当接して摺接し、当接部１０３ａが前後ガイド面５９ａに弾性的に当接して摺接し、前後被ガイド面９７ａが前後ガイド面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 75 in the longitudinal direction 51 of the article support body 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. .
また物品横押し体７５が重い物品１６０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７５が少し変位することになる。すなわち、物品１６０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ガイド部９６，９７が上昇して上位被ガイド面９６ｃ，９７ｃが凸状部５３の扁平面５３ａに下方から当接し、また物品１６０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ガイド面９６ａが前後ガイド面５９ａに内側から当接することになる。
Further, when the article lateral pusher 75 is in a heavy load state in which the heavy article 160 is laterally moved, the article lateral pusher 75 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.
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７５の往復移動は、上位被ガイド面９６ｃ，９７ｃや当接部１０１ａが扁平面５３ａに当接して摺接し、下位被ガイド面９６ｂ，９７ｂが下位ガイド面５９ｂ，６０ｂに当接して摺接し、前後被ガイド面９６ａや当接部１０３ａが前後ガイド面５９ａに当接して摺接し、前後被ガイド面９７ａが前後ガイド面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 75 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.
これらにより前記物品横押し体７５の往復移動は、前後の被ガイド部９６，９７を介して、物品支持体５０におけるガイド部５９，６０に嵌合されてガイドされる状態で、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７５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。
Thus, the reciprocating movement of the article laterally pressing body 75 is guided and 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 75 generates the same suitable sliding friction in both reciprocations. 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、そして被ガイド部９６，９７の上面を、扁平面５３ａに下方から対向する上位被ガイド面９６ｃ，９７ｃに形成していることで、物品横押し体７５群の長さ方向５１への移動時には、上位被ガイド面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７５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。
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 opposite to 53a from below, the upper guided surfaces 96c and 97c move on the flat surface 53a when the article laterally pressing body 75 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. Therefore, the intended movement can be smoothly performed without damaging the article laterally pressing body 75 and without damaging the article support 50 side.
上述したように、物品横押し体７５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８３を物品１６０に横押し作用させて、この物品１６０を分岐移動させ、分岐コンベヤ１１５Ａ，１５１Ｂに渡しているが、その際に物品１６０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１６０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 75 group moves in the transporting direction and crosses the main transport path 45, the laterally pushing action portion 83 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.
そして、横押し作用部８３の上部であるカバー部材８４の上部が、前後方向において前下方への傾斜状上面８５ａでかつ左右方向において両側下方への凸円弧状上面８５ｂとして、連続した上面８５に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７５間で物品１６０を挟み込むような状態になったとき、この物品１６０の下に、傾斜状上面８５ａの下位部分でかつ凸円弧状上面８５ｂの外側部分がスムースに潜り込み、そして物品１６０を連続した上面８５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１６０や物品横押し体７５の破損を防止し得る。なお、前端部の左右角部が円弧状側面８４ａに形成されていることで、物品１６０の下への潜り込みは、よりスムースに行えることになる。
And the upper part of the cover member 84 which is the upper part of the lateral pushing action part 83 is formed on the continuous upper surface 85 as an inclined upper surface 85a in the front-rear direction and a convex arcuate upper surface 85b in the left-right direction. By being formed, for example, when the article 160 is sandwiched between the front and rear article laterally pressing bodies 75 at the start of lateral pressing, the lower part of the inclined upper surface 85a is placed under the article 160. In addition, the outer portion of the convex arcuate upper surface 85b smoothly sinks and the article 160 is lifted by the continuous upper surface 85. Thereby, the intended lateral pushing movement can be made possible without being pinched, and thus the article 160 and the article lateral pushing body 75 can be prevented from being damaged. In addition, since the left and right corners of the front end are formed on the arc-shaped side surface 84a, the dive under the article 160 can be performed more smoothly.
さらに、連続した上面８５の形状によって、横押し作用部８３における側部に、横押し当接部材９０による広い横押し当接面（横押し作用面）９０ａを形成し得、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７５における横押し作用部８３間の隙間Ｓ（図６参照）を小さくして、物品１６０が入り込み難い状態で所期の横押し移動を可能にし得る。
Furthermore, the shape of the continuous upper surface 85 can form a wide lateral pushing contact surface (lateral pushing action surface) 90a by the lateral pushing contact member 90 on the side portion of the lateral pushing action portion 83, thereby stabilizing the lateral movement. It is possible to perform the push movement, and the gap S (see FIG. 6) between the lateral pushing action portions 83 in the front and rear article lateral pushing bodies 75 is reduced, and the desired lateral pushing movement is possible in a state where the article 160 is difficult to enter. Can be.
上述したように、物品横押し体７５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８３を物品１６０に横押し作用させて、この物品１６０を分岐移動させ、分岐コンベヤ１５１Ａ，１５１Ｂ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１６０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１６０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 75 group moves in the transporting direction and crosses the main transport path 45, the laterally pushing action portion 83 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.
その際に、カバー体１４０の最上面１４２ａを、前記物品支持体５０の上面５４ａと面一状のレベルに位置させるとともに、分岐経路１５０Ａ，１５０Ｂの分岐搬送面１５０ａ，１５０ｂを最上面１４２ａと面一状のレベルに位置させていることで、物品支持体５０側からの物品１６０は、最上面１４２ａから分岐搬送面１５０ａ，１５０ｂへと、上下にガタつくことなくスムースに分岐移動し得、以て物品１６０の損傷や騒音の発生を防止し得る。
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.
さらにカバー体１４０の内端部分を上面５４ａに対して下降する傾斜上面１４２ａに形成していることで、たとえば物品１６０自体が軟らかいものや、物品１６０の包装体が軟らかいもので、その撓みによって上面５４ａに垂れ下がり状に接触していたとしても、分岐移動時に上面５４ａから最上面１４２ａへ移行する際に、まず傾斜上面１４２ａにより受け止めて最上面１４２ａ側へ案内することになり、以て垂れ下がり部分がカバー体１４０の下に入り込むことなく、このカバー体１４０の上を確実に分岐移動し得る。
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.
また、カバー体１４０の側板部１４１と上板部１４２とが成すコーナー部１４３の内面側に凹部１４４を形成していることで、物品支持体５０側からの物品１６０が最上面１４２ａに接触した際に大きな衝撃があったとき、上板部１４２が凹部１４４を介して曲がり状となり、以て衝撃を緩衝し得る。
［実施の形態２］
次に、本発明の実施の形態２を、図２１、図２２に基づいて説明する。
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.

In the second embodiment, the upper part (upper surface shape) of the cover member 84 includes the rear part (top part), and the inclined upper surface in the front-rear direction is a convex arcuate upper surface 85f and the lower side in the left-right direction. A convex arc-shaped upper surface 85b is formed on the continuous upper surface 85, and a rear end portion is formed on a vertical rear surface 85e that descends via a convex arc-shaped and sharply descending corner surface 85d. By forming the continuous upper surface 85, the entire surface can be curved to have a good appearance.
この実施の形態２においては、たとえば横押し開始時において、前後の物品横押し体７５間で物品１６０を挟み込むような状態になったとき、この物品１６０の下に、凸円弧状上面８５ｆの下位部分でかつ凸円弧状上面８５ｂの外側部分がスムースに潜り込み、そして物品１６０を連続した上面８５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１６０や物品横押し体７５の破損を防止し得る。さらに、連続した上面８５の形状によって、全体をより曲面化して見栄えの良いものとし得る。なお、外嵌部７６の前部の形状や、上板材７７に対するカバー部材８４の前縁の係合構成は多少変化しているが、基本的には実施の形態１と同様である。
［実施の形態３］
次に、本発明の実施の形態３を、図２３、図２４に基づいて説明する。
In the second embodiment, for example, when the article 160 is sandwiched between the front and rear article laterally pressing bodies 75 at the start of the lateral pressing, the lower side of the convex arcuate upper surface 85f is placed under the article 160. The part and the outer part of the convex arcuate upper surface 85 b smoothly sunk, and the article 160 is lifted by the continuous upper surface 85. Thereby, the intended lateral pushing movement can be made possible without being pinched, and thus the article 160 and the article lateral pushing body 75 can be prevented from being damaged. Further, the shape of the continuous upper surface 85 can make the entire surface more curved and have a good appearance. Note that the shape of the front portion of the outer fitting portion 76 and the engagement configuration of the front edge of the cover member 84 with respect to the upper plate member 77 have changed somewhat, but are basically the same as in the first embodiment.

In the third embodiment, the upper portion (upper surface shape) of the cover member 84 is formed on the continuous upper surface 85 as an inclined upper surface 85a in the front-rear direction and a convex arc-shaped upper surface 85b in the left-right direction. At the same time, the top is formed on a horizontal elliptical upper surface 85g, and the rear part around the elliptical upper surface 85g is formed on an elliptical conical surface 85h.
