Description

本発明は、多数のチェーン単位部材を屈曲可能に連結して載置された被搬送物を搬送するキャタピラー型チェーンコンベヤに関する。   TECHNICAL FIELD The present invention relates to a caterpillar type chain conveyor that conveys an object to be conveyed placed by connecting a large number of chain unit members in a bendable manner.

本出願人は、特許文献1に示すチェーンコンベヤを使用し、載置された被搬送物を所定の位置へ搬送する搬送システムを提案した。該搬送システムにおいて使用するチェーンコンベヤは、搬送直交方向幅の間隔をおいて相対配置して固定バーにより連結された一対の本体フレームの一方端部に電動モータに連結された駆動軸９及び他方端部に従動軸が夫々回転可能に支持されると共にこれら駆動軸及び従動軸に固定されたスプロケットにキャタピラーチェーンを掛渡し、電動モータの駆動に伴って本体フレームを摺動するキャタピラーチェーン上に載置された被搬送物を搬送するように構成される。   The present applicant has proposed a conveyance system that uses the chain conveyor shown in Patent Document 1 and conveys the object to be conveyed to a predetermined position. The chain conveyor used in the transport system includes a drive shaft 9 connected to an electric motor at one end of a pair of main body frames that are relatively arranged at intervals in the width direction of transport and connected by a fixed bar, and the other end. The driven shaft is supported rotatably, and the caterpillar chain is passed over the drive shaft and the sprocket fixed to the driven shaft, and placed on the caterpillar chain that slides on the body frame as the electric motor is driven. It is comprised so that the conveyed to-be-conveyed object may be conveyed.

該キャタピラーチェーンは、フッ化樹脂で、載置板の両側にて搬送方向上手へ延出する外リンク板及び搬送方向下手へ延出する内リンク板を有した多数の単位部材相互を互いに重なり合った内リンク板及び外リンク板に固定軸を挿通して屈曲するように構成してなる。 The caterpillar chain is made of a fluororesin, and a plurality of unit members having an outer link plate extending to the upper side in the conveying direction and an inner link plate extending to the lower side in the conveying direction are overlapped with each other on both sides of the mounting plate. A fixed shaft is inserted into the inner link plate and the outer link plate and bent.

該チェーンコンベヤは、キャタピラーチェーンの単位部材が活動性に優れたフッ化樹脂で形成されるが、本体フレーム上を摺動するように掛渡されるため、経時使用に伴って単位部材が摩耗し易く、耐久性が悪い問題を有している。また、搬送時においては、上記摩耗により摩耗粉が発生して周囲の雰囲気を汚染し、摩耗粉が被搬送物に付着して品質を低下させる問題を有している。特に、高いクリーン度が要求されるクリーンルーム内にて加工することが要求される被搬送物を搬送する用途には、上記チェーンコンベヤを使用することができなかった。 In the chain conveyor, the unit member of the caterpillar chain is made of fluororesin having excellent activity. However, since the unit member is slid over the main body frame, the unit member is easily worn with time. , Have the problem of poor durability. Further, at the time of transport, there is a problem that wear powder is generated due to the above-mentioned wear and contaminates the surrounding atmosphere, and the wear powder adheres to the object to be transported and deteriorates the quality. In particular, the chain conveyor cannot be used for an application for conveying an object to be conveyed that is required to be processed in a clean room where a high degree of cleanness is required.

チェーン単位部材相互を、搬送直交方向に軸線を有し、かつ上記支持面上にて転動する転動ローラを設けて屈曲可能に連結してコンベヤチェーンを構成することを最良の実施形態とする。   It is the best embodiment to form a conveyor chain by connecting chain unit members to each other so as to be able to bend by providing a rolling roller having an axis in the direction perpendicular to the conveyance and rolling on the support surface. .

以下、実施例を示す図に従って本発明を説明する。
図1乃至図4に示すように、キャタピラー型チェーンコンベヤ１の本体フレーム３は、長手方向が被搬送物５の搬送長さで、長手直交方向が被搬送物５の幅に応じた長さで、上面に支持面３ａが形成される。該本体フレー３の搬送方向下手側端部には、電動モータ７に連結され、搬送直交方向に軸線を有した駆動軸９が回転可能に軸支され、該駆動軸９には駆動スプロケット等の駆動回転体１１が軸線方向に対して適宜の間隔をおいて固定される。図示の例では、駆動軸９の軸線方向端部側に駆動回転体１１を固定した例を示すが、これに限定されるものではない。 The present invention will be described below with reference to the drawings showing examples.
As shown in FIGS. 1 to 4, the main body frame 3 of the caterpillar type chain conveyor 1 has a longitudinal direction corresponding to the conveyance length of the object to be conveyed 5 and a longitudinal orthogonal direction corresponding to the width of the object to be conveyed 5. The support surface 3a is formed on the upper surface. A drive shaft 9 connected to an electric motor 7 and having an axis line in the direction perpendicular to the conveyance is rotatably supported at the lower end of the main body frame 3 in the conveyance direction. The drive shaft 9 includes a drive sprocket or the like. The drive rotator 11 is fixed at an appropriate interval with respect to the axial direction. In the example shown in the figure, an example is shown in which the drive rotator 11 is fixed to the end of the drive shaft 9 in the axial direction, but the present invention is not limited to this.

また、該本体フレー３の搬送方向上手側端部には、搬送直交方向に軸線を有した従動軸１３が回転可能に軸支され、該従動軸１３には従動スプロケット等の従動回転体１５が上記駆動回転体１１に一致して固定される。そして上記駆動回転体１１及び従動回転体１５には、キャタピラー型のコンベヤチェーン１７が、上記支持面３ａ上にて支持されるように掛渡される。   Further, a driven shaft 13 having an axis in the conveyance orthogonal direction is rotatably supported at the upper end of the main body frame 3 in the conveying direction, and a driven rotating body 15 such as a driven sprocket is provided on the driven shaft 13. The drive rotating body 11 is fixed and matched. A caterpillar type conveyor chain 17 is stretched over the drive rotating body 11 and the driven rotating body 15 so as to be supported on the support surface 3a.

上記コンベヤチェーン１７は、フッ化樹脂により成形された多数のチェーン単位部材１９相互を無端状で、互いに屈曲するように連結した構造からなる。該チェーン単位部材１９は、搬送直交方向に対する被搬送物５の幅に一致し、搬送直交方向へ延出する載置板２１の長手方向両端部にて垂下する一対の側板２３の搬送方向上手側にて搬送方向へ延出する内リンク板２５及び該側板２３の搬送方向下手側にて搬送方向へ延出して内リンク板２５の外側に位置する外リンク板２７を一体形成したリンク部材２８と、重ね合わされた外リンク板２７及び内リンク板２５の中央部に形成された軸支孔２５ａ・２７ａ内に挿通される連結軸２９と、該連結軸２９に回転可能に支持され、外周下部が外リンク板２７及び内リンク板２５の下端から下方へ突出して支持面３ａ上を転動する外径の転動ローラ３１とから構成される。   The conveyor chain 17 has a structure in which a large number of chain unit members 19 formed of a fluororesin are connected to each other so as to be bent endlessly. The chain unit member 19 coincides with the width of the object to be conveyed 5 in the conveyance orthogonal direction, and is on the upper side in the conveyance direction of the pair of side plates 23 that hang down at both longitudinal ends of the mounting plate 21 extending in the conveyance orthogonal direction. A link member 28 integrally formed with an inner link plate 25 extending in the transport direction and an outer link plate 27 extending in the transport direction on the lower side of the side plate 23 in the transport direction and positioned outside the inner link plate 25. , A connecting shaft 29 inserted into shaft support holes 25a and 27a formed at the center of the overlapped outer link plate 27 and inner link plate 25, and rotatably supported by the connecting shaft 29. The outer link plate 27 and the inner link plate 25 are composed of an outer diameter rolling roller 31 that protrudes downward from the lower end of the inner link plate 25 and rolls on the support surface 3a.

上記リンク部材２８は、搬送直交方向に対する被搬送物５の幅に応じた長さの載置板２１を有するように形成され、被搬送物５の幅に応じて複数種類、用意される。また、転動ローラ３１は、上記リンク部材２８における内リンク板２５間の間隔に応じた軸線長さに形成される。   The link member 28 is formed so as to have a mounting plate 21 having a length corresponding to the width of the transported object 5 with respect to the transport orthogonal direction, and a plurality of types are prepared according to the width of the transported object 5. The rolling roller 31 is formed to have an axial length corresponding to the interval between the inner link plates 25 in the link member 28.

なお、一方側の外リンク板２７及び内リンク板２５側から挿入されて他方の外リンク板２７及び内リンク板２５から突出した連結軸２９の軸端部には、段差部２９ａが形成され、該段差部２９ａに挿嵌されるＣリング等の抜け止め部材２９ｂにより連結軸２９が抜け止めされる。また、上記軸支孔２５ａ周縁の内リンク板２５内面には、連結突部３７より若干長い軸線長さが内側へ突出するスペ―サ用のスリーブ２５ｂが一体形成される。   A stepped portion 29a is formed at the shaft end portion of the connecting shaft 29 inserted from the outer link plate 27 and inner link plate 25 side on one side and protruding from the other outer link plate 27 and inner link plate 25, The connecting shaft 29 is prevented from coming off by a retaining member 29b such as a C-ring inserted into the stepped portion 29a. Further, a spacer sleeve 25b is integrally formed on the inner surface of the inner link plate 25 at the periphery of the shaft support hole 25a.

上記転動ローラ３１は、軸線方向が上記一対の内リンク板２５におけるスリーブ２５ｂ間の間隔を等分割した軸線長さからなる少なくとも２個以上（図示の例は、３個とする。）の単位ローラ３３相互を軸線方向へ連結して構成される。各単位ローラ３３の中心部には、上記連結軸２９が挿通される軸孔３５が軸線方向へ貫通して形成されると共に各端面には、該軸孔３５を中心とする対角位置に連結突部３７及び連結凹部３９がそれぞれ形成される。これら３個の単位ローラ３３は、お互いに対向し合う連結突部３７を連結凹部３９に挿嵌して一体化して転動ローラ３１を構成する。   The rolling roller 31 is a unit of at least two or more (three in the illustrated example) whose axial direction is an axial length obtained by equally dividing the interval between the sleeves 25b of the pair of inner link plates 25. The rollers 33 are connected to each other in the axial direction. A shaft hole 35 through which the connecting shaft 29 is inserted is formed in the central portion of each unit roller 33 so as to penetrate in the axial direction, and each end surface is connected to a diagonal position centering on the shaft hole 35. The protrusion 37 and the connection recessed part 39 are each formed. These three unit rollers 33 constitute the rolling roller 31 by integrally connecting the connecting projections 37 facing each other into the connecting recesses 39.

なお、図示の例では、３個の単位ローラ３３を軸線方向へ連結して転動ローラ３１を構成したが、内リンク板２５間の幅に応じた個数の単位ローラ３３を軸線方向へ連結して軸線方向が長尺の転動ローラ３１を構成すればよい。   In the illustrated example, three unit rollers 33 are connected in the axial direction to form the rolling roller 31. However, the number of unit rollers 33 corresponding to the width between the inner link plates 25 is connected in the axial direction. Thus, the rolling roller 31 having a long axial direction may be configured.

次に、上記のように構成されたキャタピラー型チェーンコンベヤ１による搬送作用を説明する。   Next, the conveying action by the caterpillar type chain conveyor 1 configured as described above will be described.

電動モータ７の駆動により駆動軸９を所定の方向へ回転してコンベヤチェーン１７を図示する実線矢印方向へ走行し、走行するコンベヤチェーン１７の各載置板２１上に被搬送物５を乗せて搬送させる。このとき、図５に示すように本体フレーム３上を走行するコンベヤチェーン１７は、支持面３ａに対して各チェーン単位部材１９の転動ローラ３１が回転して走行するため、支持面３ａに対する走行抵抗を低減すると共に各チェーン単位部材１９の摩耗を低減する。また、コンベヤチェーン１７の各チェーン単位部材１９は、支持面３ａに対して転動する転動ローラ３１により摩耗が低減することにより摩耗粉の発生が低減される。更に、転動ローラ３１の軸線方向端面においては、単位ローラ３３の連結突部３７が突出しているが、内リンク板２５の内面と転動ローラ３１の各端面の間に連結突部３７の突出幅より若干長い軸線長さのスリーブ２５ｂが介在するため、これら連結突部３７が内リンク板２５の内面に当接して回転不良になることが防止される。   By driving the electric motor 7, the drive shaft 9 is rotated in a predetermined direction so that the conveyor chain 17 travels in the direction of the solid arrow shown in the figure, and the object 5 is placed on each mounting plate 21 of the traveling conveyor chain 17. Transport. At this time, as shown in FIG. 5, the conveyor chain 17 traveling on the main body frame 3 travels with the rolling roller 31 of each chain unit member 19 rotating relative to the support surface 3a. The resistance is reduced and the wear of each chain unit member 19 is reduced. Further, the wear of each chain unit member 19 of the conveyor chain 17 is reduced by the rolling roller 31 that rolls with respect to the support surface 3a, thereby reducing the generation of wear powder. Further, the connecting protrusion 37 of the unit roller 33 protrudes on the end surface in the axial direction of the rolling roller 31, but the connecting protrusion 37 protrudes between the inner surface of the inner link plate 25 and each end surface of the rolling roller 31. Since the sleeve 25b having an axial length slightly longer than the width is interposed, it is possible to prevent the connection protrusions 37 from coming into contact with the inner surface of the inner link plate 25 and causing poor rotation.

搬送直交方向に対する幅が長い被搬送物５を搬送する際には、図６に示すように被搬送物５の幅に応じた長さの載置板２１を有したリンク部材２８に対し、例えば図示の例では４個（４個以上であってもよいことは、勿論である。）の単位ローラ３３を軸線方向に連結して一体化した転動ローラ３１を構成した後、これらチェーン単位部材１９相互に上記転動ローラ３１を回転するように支持しながら連結してコンベヤチェーン１７を構成する。 When transporting the transported object 5 having a long width with respect to the transport orthogonal direction, for example, with respect to the link member 28 having the mounting plate 21 having a length corresponding to the width of the transported object 5 as shown in FIG. In the example shown in the drawing, four chain rollers (of course, four or more) can be integrated by connecting the unit rollers 33 in the axial direction. 19 Conveyor chain 17 is formed by connecting the rolling rollers 31 while supporting them so as to rotate.

即ち、４個の単位ローラ３３相互を、対向する端面の連結突部３７を連結凹部３９に嵌合して一体化することにより転動ローラ３１を形成した後、リンク部材２８相互を、外リンク板２７間に配置された内リンク板２５間に上記転動ローラ３１を配置した後、一方の外リンク板２７側から連結軸２９をそれぞれの軸支孔２５ａ・２７ａ及び単位ローラ３３の軸孔３５内に挿通して軸端部を他方の外リンク板２７から突出させた後、突出した軸端の段差部２９ａに抜け止め部材２９ｂを嵌め込んでリンク部材２８に転動ローラ３１を取付けると同時にリンク部材２８相互を連結してコンベヤチェーン１７を構成する。 That is, after the four unit rollers 33 are integrated by fitting the connecting projections 37 on the opposite end faces into the connecting recesses 39 to form the rolling roller 31, the link members 28 are connected to the outer links. After the rolling roller 31 is arranged between the inner link plates 25 arranged between the plates 27, the connecting shaft 29 is connected to the respective shaft support holes 25a and 27a and the shaft holes of the unit roller 33 from the outer link plate 27 side. 35, the shaft end portion is protruded from the other outer link plate 27, and the retaining member 29b is fitted into the protruding step portion 29a of the shaft end so that the rolling roller 31 is attached to the link member 28. At the same time, the link members 28 are connected to each other to form the conveyor chain 17.

図７に示すように実施例２に係る転動ローラ７１は、軸線方向が上記一対の内リンク板２５におけるスリーブ２５ｂ間の間隔を等分割した軸線長さからなり、軸線方向端部側に位置する端部ローラ７３及び中間部に位置する連結ローラ７５を軸線方向へ連結して構成される。各端部ローラ７３は、内リンク板２５側に位置する端面の中心部に軸支孔２５ａ・２７ａを挿通する固定軸７７が回り止めされて挿嵌される固定軸孔７９が、また他方の端面中心部に連結ピン８１の一部（半分）が挿嵌される連結孔８３がそれぞれ形成されると共に上記連結孔８３を中心とする対角位置に連結突部８５及び連結凹部８７がそれぞれ形成される。   As shown in FIG. 7, the rolling roller 71 according to the second embodiment is configured such that the axial direction has an axial length obtained by equally dividing the interval between the sleeves 25 b in the pair of inner link plates 25, and is positioned on the end side in the axial direction. The end roller 73 and the connecting roller 75 positioned in the middle are connected in the axial direction. Each end roller 73 has a fixed shaft hole 79 in which a fixed shaft 77 inserted through the shaft support holes 25a and 27a is prevented from rotating at the center portion of the end surface located on the inner link plate 25 side, and the other end roller 73 is inserted. A connection hole 83 into which a part (half) of the connection pin 81 is inserted is formed at the center of the end surface, and a connection protrusion 85 and a connection recess 87 are formed at diagonal positions with the connection hole 83 as the center. Is done.

また、連結ローラ７５は、両端面の中心部に連結ピン８１の一部（半分）が挿嵌される連結孔８９がそれぞれ形成されると共に上記連結孔８９を中心とする対角位置に連結突部９１及び連結凹部９３がそれぞれ形成される。 Further, the connecting roller 75 is formed with connecting holes 89 into which a part (half) of the connecting pin 81 is inserted and fitted at the center of both end faces, and at the diagonal positions centering on the connecting hole 89. The part 91 and the connection recessed part 93 are each formed.

転動ローラ７１は、両側の端部ローラ７３間に連結ローラ７５を配置し、連結孔８３・８９内に連結ピン８１をそれぞれ挿嵌すると共に相対する連結突部９１を連結凹部８７に、また連結突部８５を連結凹部９３にそれぞれ挿嵌して軸線方向へ連結して構成される。なお、図７及び図８において実施例１と実質的に同じ部材に付いては、同一の符号を付して詳細な説明を省略する。
（図８参照） In the rolling roller 71, a connecting roller 75 is disposed between the end rollers 73 on both sides, and connecting pins 81 are respectively inserted into the connecting holes 83 and 89, and the opposing connecting protrusions 91 are connected to the connecting recesses 87. The connection protrusions 85 are respectively inserted into the connection recesses 93 and connected in the axial direction. 7 and 8, the same reference numerals are given to substantially the same members as those in the first embodiment, and the detailed description is omitted.
(See Figure 8)

そして上記のように構成された転動ローラ７１は、一方のリンク部材２８における外リンク板２７間に他方のリンク部材２８における内リンク板２５を配置した状態で軸支孔２５ａ・２７ａ内に挿入される固定軸７７を端部ローラ７３の固定軸孔７９内に回り止め状態で挿嵌して取付けられると共にチェーン単位部材１９相互を屈曲するように連結してコンベヤチェーン１７を形成する。 The rolling roller 71 configured as described above is inserted into the shaft support holes 25a and 27a with the inner link plate 25 of the other link member 28 disposed between the outer link plates 27 of the one link member 28. The fixed shaft 77 to be fixed is inserted into the fixed shaft hole 79 of the end roller 73 in a non-rotating state and attached, and the chain unit members 19 are connected to bend each other to form the conveyor chain 17.

図９及び図１０に示すように実施例３に係るコンベヤチェーン１７のチェーン単位部材１０１は、被搬送物５が載置される載置板１０２の下部にて搬送方向の一方へ延出し、中心部に軸受孔１０３が形成された軸受リンク部１０５及び搬送方向の他方側にて上記軸受リンク部１０５の搬送直交方向両端に対して所要の間隔をおいて平行延出し、中心部に軸支孔１０７が形成された前後一対の軸支リンク部１０９が合成樹脂により一体形成されたリンク部材１１１と、上記軸受リンク部１０５の搬送直交方向両端と各軸支リンク部１０９の内面間の間隙にそれぞれ配置され、中心部に軸受孔１１３が形成された複数個（図示の例では、２個とする。）の単位ローラ１１５を連結した転動ローラ１１７と、上記軸受孔１０３，１１３及び軸支孔１０７内に挿通される固定軸１１９から構成される。   As shown in FIGS. 9 and 10, the chain unit member 101 of the conveyor chain 17 according to the third embodiment extends to one side in the conveyance direction at the lower part of the mounting plate 102 on which the article to be conveyed 5 is placed, The bearing link portion 105 in which the bearing hole 103 is formed in the portion and the other end in the conveying direction extend in parallel to both ends in the conveyance orthogonal direction of the bearing link portion 105 at a predetermined interval, and the shaft support hole in the central portion A link member 111 in which a pair of front and rear shaft link portions 109 formed with 107 is integrally formed of a synthetic resin, and a gap between both ends of the bearing link portion 105 in the conveyance orthogonal direction and an inner surface of each shaft link portion 109, respectively. A rolling roller 117 that is arranged and has a plurality of (two in the illustrated example) unit rollers 115 each having a bearing hole 113 formed in the center, and the bearing holes 103 and 113 and the shaft support hole. 1 Composed of the fixed shaft 119 is inserted into the 7.

上記単位ローラ１１５の搬送直交方向の両端面には、上記軸受孔１１３を中心とする対角位置に係合突部１２１及び係合凹部１２３がそれぞれ形成され、それぞれの係合突部１２１を対向する係合凹部１２３に係合して複数個の単位ローラ１１５を軸線方向へ連結して転動ローラ１１７を構成する。 Engagement protrusions 121 and engagement recesses 123 are formed at diagonal positions centering on the bearing hole 113 on both end surfaces of the unit roller 115 in the conveyance orthogonal direction, and the engagement protrusions 121 are opposed to each other. A plurality of unit rollers 115 are connected in the axial direction by engaging with the engaging recesses 123 to form a rolling roller 117.

搬送直交方向に対して幅広の被搬送物５を搬送する際には、載置板１０２の搬送直交方向が被搬送物５の搬送直交方向幅に応じた長さのリンク部材１１１を選択する。該リンク部材１１１にあっては、軸受リンク部１０５の両端面と軸支リンク部１０９の内面の間隔が幅広になるため、両者間に配置される転動ローラ１１７を軸線方向が上記間隔に応じた長さへ変更する必要がある。 When transporting the object to be transported 5 wider than the transport orthogonal direction, the link member 111 having a length corresponding to the transport orthogonal direction width of the transported object 5 is selected in the transport orthogonal direction of the mounting plate 102.
