そして、図5(a)ないし(e)に示すように、回動駆動手段21のモータ22が駆動して出力軸23が一方向(図中、矢印方向)に回転すると、各リンク24,25,26,27が回動することにより回動コンベヤ6が支軸(回動中心軸線X)12を中心として上下方向に回動する。そして、回動コンベヤ6は、上方回動により図5(e)に示す水平状の搬送状態となり、下方回動により図5(a)に示す傾斜状の仕分傾斜状態となる。   As shown in FIGS. 5A to 5E, when the motor 22 of the rotational drive means 21 is driven and the output shaft 23 rotates in one direction (in the direction of the arrow in the figure), the links 24, 25 , 26 and 27 rotate, the rotating conveyor 6 rotates in the vertical direction around the support shaft (rotation center axis X) 12. And the rotation conveyor 6 will be in the horizontal conveyance state shown to FIG.5 (e) by upper rotation, and will be in the inclined sorting inclination state shown to Fig.5 (a) by rotation below.

分岐搬送部3は、図1に示すように、仕分傾斜状態の回動コンベヤ6から滑落してくる物品Wを受け入れて搬送する下り傾斜状のシュート31と、このシュート31からの物品Wを受け入れて搬送するコンベヤ32とを備えている。シュート31の回動コンベヤ6側の端部には、物品Wと接触して物品Wの向きを変更する向き変更手段33が設けられている。この向き変更手段33は、例えば物品Wと接触して物品Wを90度回動させるターンローラ34で、このターンローラ34は上下方向の軸(図示せず)を中心として回動可能となっている。   As shown in FIG. 1, the branch conveyance unit 3 accepts and conveys the articles W from the down chute 31 that receives and conveys the articles W sliding down from the rotating conveyor 6 in the sorting inclined state. And a conveyor 32 for transporting. At the end of the chute 31 on the rotating conveyor 6 side, there is provided a direction changing means 33 that contacts the article W and changes the orientation of the article W. The direction changing means 33 is, for example, a turn roller 34 that contacts the article W and rotates the article W by 90 degrees. The turn roller 34 is rotatable about a vertical axis (not shown). Yes.

次に、上記仕分装置1の作用等を説明する。   Next, the operation of the sorting apparatus 1 will be described.

仕分対象物である物品Wが主搬送部2にて搬送方向Aに搬送されている途中で、物品Wに対応する仕分情報に基づいて回動コンベヤ6が回動中心軸線Xを中心とする下方回動により水平状の搬送状態から仕分傾斜状態に切り換えられると、その物品Wは、仕分傾斜状態の回動コンベヤ6の搬送ローラ15上を自重により搬送方向A側方に向って滑落し、対応する分岐搬送部3に仕分けられる。この仕分けられた物品Wは、ターンローラ34にて向きが変更された後、シュート31およびコンベヤ32にて搬送される。   While the article W, which is the sorting object, is being transported in the transport direction A by the main transport unit 2, the rotating conveyor 6 is located below the rotation center axis X based on the sorting information corresponding to the article W. When the rotation is switched from the horizontal conveyance state to the sorting inclined state, the article W slides down on the conveying roller 15 of the rotating conveyor 6 in the sorting inclined state toward the side of the conveying direction A by its own weight. Are sorted into the branch conveyance unit 3 to be The sorted articles W are transported by the chute 31 and the conveyor 32 after the direction is changed by the turn roller 34.

そして、例えば次に続く物品Wが1つ前の物品Wと同じ分岐搬送部3に仕分けられるべきものである場合には、回動コンベヤ6は仕分傾斜状態に維持され、その物品Wは、搬送コンベヤ5から仕分傾斜状態の回動コンベヤ6の搬送ローラ15上に乗り移った後、その搬送ローラ15上を自重により搬送方向A側方に向って滑落し、対応する分岐搬送部3に仕分けられる。 Then, for example, then when the subsequent article W is of Rubeki sorted in the same branch conveying unit 3 and the preceding article W is rotated conveyor 6 is maintained in sorting inclined state, the article W is After transferring from the conveyor 5 onto the conveyor roller 15 of the rotating conveyor 6 in the sorting inclined state, the conveyor roller 15 slides down toward the side of the conveyance direction A by its own weight, and is sorted into the corresponding branch conveyor unit 3. .

なお、次に続く物品Wが1つ前の物品Wとは異なる分岐搬送部3に仕分けるべきものである場合には、回動コンベヤ6は回動中心軸線Xを中心とする上方回動により仕分傾斜状態から水平状の搬送状態に切り換えられ、その物品Wは、搬送コンベヤ5から搬送状態の回動コンベヤ6の搬送ローラ15上に乗り移り、そのまま搬送ローラ15にて搬送方向Aに向って搬送される。   In addition, when the next article W is to be sorted into the branch conveyance unit 3 different from the previous article W, the rotating conveyor 6 is sorted by rotating upward about the rotation center axis X. The article W is switched from the inclined state to the horizontal conveying state, and the article W is transferred from the conveying conveyor 5 onto the conveying roller 15 of the rotating conveyor 6 in the conveying state, and is conveyed in the conveying direction A by the conveying roller 15 as it is. The

このように仕分装置1によれば、複数個の物品Wを同じ分岐搬送部3に連続して仕分ける場合に、回動コンベヤ6を搬送状態に一旦切り換える必要がなく、このため、例えば同じ分岐搬送部3に仕分ける隣合う物品W間の距離を短くでき、効率よく仕分作業ができる。   As described above, according to the sorting apparatus 1, when the plurality of articles W are sequentially sorted into the same branch transport unit 3, there is no need to temporarily switch the rotating conveyor 6 to the transport state. The distance between the adjacent articles W sorted into the part 3 can be shortened, and sorting work can be performed efficiently.

また、搬送コンベヤ5および回動コンベヤ6はいずれも短機長コンベヤであり、主搬送部2はその短機長コンベヤが連設されて構成されているため、構造がきわめてシンプルで、メンテナンス性も良好である。   In addition, the transport conveyor 5 and the rotating conveyor 6 are both short-length conveyors, and the main transport unit 2 is constructed by connecting the short-length conveyors, so that the structure is extremely simple and maintainability is good. is there.

なお、上記実施の形態では、主搬送部2の一側方のみに複数の分岐搬送部3を直交状に配設し、物品Wを搬送方向A一側方にのみ仕分ける構成について説明したが、例えば図6に示すように、主搬送部2の一側方に複数の一方側分岐搬送部3aを直交状に配設しかつ主搬送部2の他側方に複数の他方側分岐搬送部3bを直交状に配設し、物品Wを搬送方向Aの両側方に仕分ける構成でもよい。   In the above embodiment, a configuration has been described in which a plurality of branch conveyance units 3 are arranged orthogonally only on one side of the main conveyance unit 2 and the articles W are sorted only on one side in the conveyance direction A. For example, as shown in FIG. 6, a plurality of one-side branch transport units 3a are arranged orthogonally on one side of the main transport unit 2 and a plurality of other side branch transport units 3b on the other side of the main transport unit 2 May be arranged orthogonally, and the article W may be sorted on both sides in the conveyance direction A.

この図6に示す仕分装置1の各回動コンベヤ6は、図1に示すものとは異なり、図7ないし図10に示すように、方側分岐搬送部3b側に位置し主搬送部2の搬送方向Aに沿った水平な第1回動中心軸線X1を中心として上下方向に回動可能であり、かつ方側分岐搬送部3a側に位置し主搬送部2の搬送方向Aに沿った水平な第2回動中心軸線X2を中心として上下方向に回動可能である。 The respective rotary conveyor 6 of the sorting apparatus 1 shown in FIG. 6, differs from that shown in FIG. 1, as shown in FIGS. 7 to 10, located on the other side in the branch conveying portion 3b side of the main transport unit 2 transport is rotatable in the vertical direction around a horizontal first pivot center axis X1 along the direction a, and along the located one side branch conveying portion 3a side conveying direction a of the main conveyor section 2 It can be pivoted up and down about a horizontal second pivot center axis X2.

各回動コンベヤ6は、第1回動中心軸線X1を中心とする上下回動により水平な搬送状態および一方側仕分傾斜状態に選択的に切り換えられ、第2回動中心軸線X2を中心とする上下回動により水平な搬送状態および他方側仕分傾斜状態に選択的に切り換えられる。すなわち、各回動コンベヤ6は、水平状の搬送状態と、一方側分岐搬送部3a側に向って下り傾斜状の一方側仕分傾斜状態と、他方側分岐搬送部3b側に向って下り傾斜状の他方側仕分傾斜状態とに選択的に切り換えられる。   Each rotating conveyor 6 is selectively switched between a horizontal conveying state and a one-side sorting inclined state by rotating up and down around the first rotation center axis X1, and up and down around the second rotation center axis X2. By the rotation, it is selectively switched between a horizontal conveyance state and the other-side sorting inclination state. That is, each rotating conveyor 6 has a horizontal conveyance state, a one-side sorting inclination state that is inclined downward toward the one-side branch conveyance unit 3a, and a downward-inclination shape toward the other-side branch conveyance unit 3b. It is selectively switched to the other side sorting inclination state.

そして、回動コンベヤ6は、水平状の搬送状態時には搬送方向A上流の搬送コンベヤ5から物品Wを受け入れこの受け入れた物品Wをそのまま搬送方向Aに搬送し、一方側仕分傾斜状態時には搬送方向A上流の搬送コンベヤ5から物品Wを受け入れこの受け入れた物品Wをその自重により搬送方向A側方(図6では、上方向)に滑落させて対応する一方側分岐搬送部3aに仕分け、他方側仕分傾斜状態時には搬送方向A上流の搬送コンベヤ5から物品Wを受け入れこの受け入れた物品Wをその自重により搬送方向A側方(図6では、下方向)に滑落させて対応する他方側分岐搬送部3bに仕分ける。   The rotating conveyor 6 receives the article W from the conveying conveyor 5 upstream in the conveying direction A in the horizontal conveying state and conveys the received article W in the conveying direction A as it is, and the conveying direction A in the one-side sorting inclined state. The article W is received from the upstream conveyor 5, and the received article W is slid down in the conveyance direction A side (upward in FIG. 6) by its own weight and sorted into the corresponding one-side branch conveyance unit 3a, and the other side In the inclined state, the article W is received from the conveyance conveyor 5 upstream in the conveyance direction A, and the received article W is slid down in the conveyance direction A side (downward in FIG. 6) by its own weight to correspond to the other side branch conveyance unit 3b. Sort into.

また、この回動コンベヤ6は、図7ないし図10に示すように、第1支軸(第1回動中心軸線X1)12aおよび第2支軸(第2回動中心軸線X2)12bを中心として上下方向に回動可能に支持された回動フレーム13を有している。回動フレーム13には、図4等に示すものと同様、一対の対向フレーム14が設けられ、これら両対向フレーム14間に複数の搬送ローラ15が回転可能に設けられ、これら複数の搬送ローラ15は駆動源であるローラ駆動用モータ16から出力される動力に基づいて回転して物品Wを搬送方向Aに搬送する。   Further, as shown in FIGS. 7 to 10, the rotating conveyor 6 is centered on a first support shaft (first rotation center axis X1) 12a and a second support shaft (second rotation center axis X2) 12b. As a pivot frame 13 supported so as to be pivotable in the vertical direction. As in the case shown in FIG. 4 and the like, the rotating frame 13 is provided with a pair of opposed frames 14, and a plurality of conveying rollers 15 are rotatably provided between the opposed frames 14. Rotates based on the power output from the roller driving motor 16 as a driving source, and conveys the article W in the conveying direction A.

さらに、回動コンベヤ6は、仕分情報に基づく第1回動駆動手段21aの作動により第1回動中心軸線X1を中心として上下方向に回動するとともに仕分情報に基づく第2回動駆動手段21bの作動により第2回動中心軸線X2を中心として上下方向に回動する。第1回動駆動手段21aおよび第2回動駆動手段21bは、いずれも基本的構成が図4等に示す回動駆動手段21と同じもので、駆動源であるモータ22を有し、このモータ22の出力軸23には第1リンク24の一端部が回動可能に連結され、この第1リンク24の他端部には第2リンク25の一端部が回動可能に連結されている。第2リンク25の他端部には、第3リンク26の一端部および第4リンク27の一端部が連結軸28を介してそれぞれ回動可能に連結されている。第3リンク26の他端部はコンベヤ支持体11の支軸29に回動可能に連結され、第4リンク27の他端部は支軸12a,12bに回動可能に連結されている。   Further, the rotating conveyor 6 rotates up and down around the first rotation center axis X1 by the operation of the first rotation driving means 21a based on the sorting information, and the second rotation driving means 21b based on the sorting information. As a result of this operation, it rotates in the vertical direction about the second rotation center axis X2. Each of the first rotation drive means 21a and the second rotation drive means 21b has the same basic configuration as the rotation drive means 21 shown in FIG. 4 and the like, and has a motor 22 as a drive source. One end portion of the first link 24 is rotatably connected to the output shaft 23 of 22, and one end portion of the second link 25 is rotatably connected to the other end portion of the first link 24. One end of a third link 26 and one end of a fourth link 27 are connected to the other end of the second link 25 via a connecting shaft 28 so as to be rotatable. The other end of the third link 26 is pivotally connected to a support shaft 29 of the conveyor support 11, and the other end of the fourth link 27 is rotatably connected to the support shafts 12a and 12b.

そして、第1回動駆動手段21aのモータ22が駆動して出力軸23が一方向に回転すると、各リンク24,25,26,27が回動することにより回動コンベヤ6が第1支軸(第1回動中心軸線X1)12aを中心として上下方向に回動し、その上方回動により回動コンベヤ6が水平状の搬送状態となり、その下方回動により回動コンベヤ6が傾斜状の一方側仕分傾斜状態となる。また、第2回動駆動手段21bのモータ22が駆動して出力軸23が一方向に回転すると、各リンク24,25,26,27が回動することにより回動コンベヤ6が第2支軸(第2回動中心軸線X2)12bを中心として上下方向に回動し、その上方回動により回動コンベヤ6が水平状の搬送状態となり、その下方回動により回動コンベヤ6が傾斜状の他方側仕分傾斜状態となる。   When the motor 22 of the first rotation driving means 21a is driven and the output shaft 23 rotates in one direction, the links 24, 25, 26 and 27 rotate, so that the rotating conveyor 6 becomes the first support shaft. (First rotation center axis X1) 12a is turned up and down around the center, and the turning conveyor 6 is in a horizontal conveying state by turning upward, and the turning conveyor 6 is inclined by turning downward. One side sorting inclination state is obtained. Further, when the motor 22 of the second rotation driving means 21b is driven and the output shaft 23 rotates in one direction, the links 24, 25, 26, and 27 rotate, whereby the rotating conveyor 6 becomes the second support shaft. (Second rotation center axis X2) 12b is rotated up and down around the center, and by turning upward, the rotating conveyor 6 is in a horizontal conveying state, and by rotating downward, the rotating conveyor 6 is inclined. The other side sorting inclination state is obtained.

また、一方側分岐搬送部3aおよび他方側分岐搬送部3bは、図1に示す分岐搬送部3と同様、下り傾斜状のシュート31とこのシュート31からの物品Wを受け入れて搬送するコンベヤ32とを備え、シュート31にはターンローラ34にて構成された向き変更手段33が設けられている。   Further, the one-side branch transport unit 3a and the other-side branch transport unit 3b are similar to the branch transport unit 3 shown in FIG. 1, and are a downwardly inclined chute 31 and a conveyor 32 that receives and transports articles W from the chute 31. The chute 31 is provided with a direction changing means 33 constituted by a turn roller 34.

そして、このような図6に示す仕分装置1であっても、複数個の物品Wを同じ分岐搬送部3a,3bに連続して仕分ける場合に、回動コンベヤ6を搬送状態に一旦切り換える必要がなく、このため、例えば同じ分岐搬送部3a,3bに仕分ける隣合う物品W間の距離を短くでき、効率よく仕分作業ができる等、前記図1に示すものと同様の作用効果を奏することができる。   Even in the sorting apparatus 1 shown in FIG. 6, when the plurality of articles W are successively sorted into the same branch conveyance units 3a and 3b, it is necessary to temporarily switch the rotating conveyor 6 to the conveyance state. For this reason, for example, the distance between the adjacent articles W sorted into the same branch conveyance units 3a and 3b can be shortened, and the same working effects as those shown in FIG. .

なお、上記いずれの実施の形態においても、搬送コンベヤ5および回動コンベヤ6は、搬送ローラを有するローラコンベヤである構成について説明したが、例えば無端状の搬送ベルトを有するベルトコンベヤ等でもよく、またローラコンベヤおよびベルトコンベヤを適宜組み合わせたもの等でもよい。   In any of the above embodiments, the conveyance conveyor 5 and the rotating conveyor 6 are described as a roller conveyor having conveyance rollers. However, for example, a belt conveyor having an endless conveyance belt may be used. A combination of a roller conveyor and a belt conveyor as appropriate may be used.

また、回動コンベヤ6を上下方向に回動させる回動駆動手段は、モータ22で回動するリンク24,25,26,27を用いた構成には限定されず、例えば流体圧シリンダ等の伸縮駆動手段の伸縮動作で回動コンベヤ6を回動させる構成等でもよい。   Further, the rotation driving means for rotating the rotating conveyor 6 in the vertical direction is not limited to the configuration using the links 24, 25, 26, 27 rotated by the motor 22, and for example, expansion and contraction of a fluid pressure cylinder or the like. The structure etc. which rotate the rotation conveyor 6 by the expansion-contraction operation | movement of a drive means may be sufficient.

さらに、分岐搬送部3,3a,3bを主搬送部2に対して直交状に配設した構成には限定されず、分岐搬送部3,3a,3bを主搬送部2に対して傾斜状に配設した構成等でもよい。   Further, the configuration is not limited to the configuration in which the branch transport units 3, 3 a, 3 b are arranged orthogonal to the main transport unit 2, and the branch transport units 3, 3 a, 3 b are inclined with respect to the main transport unit 2.
