また、本装置は、図６に示すように、鉛直方向に並んだ搬送機構１、振分機構２、移送機構３、ドラム機構４および積層機構５を一組として、独立した２組の振分機構２、移送機構３、ドラム機構４および積層機構５が搬送機構１の搬送方向に沿って設けられている。 In addition, as shown in FIG. 6, the present apparatus has two independent sorting units, each of which includes a transport mechanism 1, a sorting mechanism 2, a transfer mechanism 3, a drum mechanism 4, and a stacking mechanism 5 arranged in the vertical direction. The mechanism 2, the transfer mechanism 3, the drum mechanism 4, and the stacking mechanism 5 are provided along the transport direction of the transport mechanism 1.
前記搬送機構１は、図２に示すように、ワークＷの幅方向（図２の上下方向）に所定間隔を空けて平行に配置された２つのコンベアベルト１１を備え、図示略の駆動モータによりコンベアベルト１１が所定の方向（図１および図２の右方向）に高速で移動するものとなされている。このコンベアベルト１１は、ワークＷの幅方向の両端部の上面を吸着しながら、所定の方向の移動に伴ってワークＷを天吊状態で所定の方向（図１および図２の右方向）に高速で順次搬送する。 As shown in FIG. 2, the transport mechanism 1 includes two conveyor belts 11 that are arranged in parallel in the width direction of the work W (the vertical direction in FIG. 2) at a predetermined interval, and are driven by a drive motor (not shown). The conveyor belt 11 is designed to move at a high speed in a predetermined direction (rightward in FIGS. 1 and 2). The conveyor belt 11 attracts the upper surfaces of both end portions in the width direction of the work W, and moves the work W in a predetermined direction to suspend the work W in a predetermined direction (rightward in FIGS. 1 and 2). It conveys sequentially at high speed.

As shown in FIGS. 1 and 2, the distribution mechanism 2 is provided between the conveyor belts 11 of the conveyance mechanism 1. And is disposed above the conveyor belt 11.
この回転体２１は、搬送方向に湾曲する曲面状の周面２１ａを有しており、図示略の駆動モータにより回転体２１がワークＷの搬送方向（図１の左回り）に回転することにより連続的に姿勢が移行するものとなされている。 The rotating body 21 has a curved peripheral surface 21a that curves in the transport direction, and the rotating body 21 rotates in the transport direction of the workpiece W (counterclockwise in FIG. 1) by a drive motor (not shown). It is said that the posture changes continuously.
具体的には、回転体２１は、図４（ａ）に示すように、周面２１ａ（中央部）が真上を向いた姿勢から、搬送後方の斜め上に向いた姿勢に移行したあと、搬送方向後方の真後に向いた姿勢に移行する。そして、図４（ｂ）に示すように、周面２１ａが搬送方向後方の斜め下に向いた姿勢から、真下を向いた姿勢に移行したあと、搬送方向前方の斜め下に向いた姿勢に移行する。そして、さらに図４（ｃ）に示すように、周面２１ａが搬送方向前方の真前に向いた姿勢から、搬送方向前方の斜め上に向いた姿勢に移行したあと、真上を向いた姿勢に移行して、その後、同様の姿勢に移行することを連続的に繰り返す。 Specifically, as shown in FIG. 4A, the rotating body 21 shifts from a posture in which the peripheral surface 21a (central portion) faces directly upward to a posture in which the peripheral surface 21a faces diagonally upward behind the conveyance, The posture shifts to the rear right in the transport direction. Then, as shown in FIG. 4B, the peripheral surface 21a is changed from a posture in which the peripheral surface 21a is directed rearward and obliquely downward to a posture in which the peripheral surface 21a is directly downward, and then is changed to a posture obliquely downward and forward in the conveying direction. To do. Further, as shown in FIG. 4C, the posture in which the peripheral surface 21a faces straight ahead in the front in the transport direction and shifts to the posture diagonally upward in the front in the transport direction, and then faces straight up. Then, the process of shifting to the same posture is continuously repeated.
また、回転体２１は、図４に示すように、周面２１ａがワークＷの搬送面に接した姿勢となっているときに、搬送機構１により搬送されてきたワークＷを周面２１ａに当接させながら下方に向けて押し出すことによって直下のドラム機構４に振り分けるものとなされている。 Further, as shown in FIG. 4, the rotating body 21 contacts the peripheral surface 21a with the work W conveyed by the conveying mechanism 1 when the peripheral surface 21a is in a posture in contact with the conveying surface of the workpiece W. It is arranged to be distributed to the drum mechanism 4 immediately below by pushing it downward while making contact.
具体的には、回転体２１は、図４（ａ）の右図に示すように、周面２１ａが搬送方向後方の真後に向いた姿勢になったときに、搬送機構１により搬送されてきたワークＷの前端部に当接し、図４（ｂ）に示すように、そのままワークＷの搬送に同期して回転するのに伴って、周面２１ａがワークＷの上面に当接しながらワークＷを下方に向けて押し出したあと、図４（ｃ）の左図に示すように、周面２１ａが搬送方向前方の真前に向いた姿勢になったときに、ワークＷの後端部に最後に当接して、その後、周面２１ａがワークＷから離れていく。 Specifically, as shown in the right diagram of FIG. 4A, the rotating body 21 has been transported by the transport mechanism 1 when the peripheral surface 21a is in a posture facing right behind in the transport direction. As the work W abuts on the front end of the work W and rotates as it is in synchronization with the conveyance of the work W as shown in FIG. After being pushed downward, when the peripheral surface 21a is in the posture of facing forward in the transport direction, as shown in the left diagram of FIG. After the contact, the peripheral surface 21a moves away from the work W.
なお、回転体２１は、特に図４（ｃ）に示すように、周面２１ａがワークＷの搬送面から離れた姿勢となっているとき、搬送機構１により搬送されてきたワークＷを回転体２１の下方でそのまま通過させる。 Note that, as shown in FIG. 4C, the rotary body 21 rotates the work W transported by the transport mechanism 1 when the peripheral surface 21 a is in a posture away from the transport surface of the work W. Pass it directly under 21.
前記移送機構３は、図１に示すように、振分機構２の回転体２１の下方の位置に設けられ、移送方向の前方に配置された主動軸３１と、移送方向の後方に配置された従動軸３２と、主動軸３１と従動軸３２の間に配置された中間軸３３と、主動軸３１、従動軸３２、中間軸３３の間を無端状態に巻架されたコンベアベルト３４とを備え、図示略の駆動モータによりコンベアベルト３４が所定の移送方向に右回りに回転走行する。このコンベアベルト３４は、前記振分機構２の回転体２１により下方に押し出されるようにして振り分けられたワークＷの下面を吸着しながら、所定の方向の移動に伴ってワークＷを載置状態で斜め下方に移送する。 As shown in FIG. 1, the transfer mechanism 3 is provided at a position below the rotating body 21 of the distribution mechanism 2, and is provided with a main shaft 31 arranged in the front in the transfer direction and a rear side in the transfer direction. A driven shaft 32, an intermediate shaft 33 arranged between the driving shaft 31 and the driven shaft 32, and a conveyor belt 34 wound endlessly between the driving shaft 31, the driven shaft 32, and the intermediate shaft 33. The conveyor belt 34 rotates clockwise in a predetermined transfer direction by a drive motor (not shown). The conveyor belt 34 attracts the lower surface of the work W that is distributed by being pushed downward by the rotating body 21 of the distribution mechanism 2 while keeping the work W placed along with the movement in a predetermined direction. Transfer diagonally downward.
前記ドラム機構４は、図１に示すように、移送機構３の下端部の前方に設けられた円筒状のドラム４１を備え、図示略の駆動モータによりドラム４１が左回りに軸回転する。このドラム４１は、移送機構３により移送されたワークＷを周面で空気吸引方式や静電方式等により順次貼着しながら、回転の最下点まで回転搬送する。 As shown in FIG. 1, the drum mechanism 4 includes a cylindrical drum 41 provided in front of the lower end portion of the transfer mechanism 3, and the drum 41 is rotated counterclockwise by a drive motor (not shown). The drum 41 rotationally conveys the work W transferred by the transfer mechanism 3 to the lowest point of rotation while sequentially adhering the work W on the peripheral surface by an air suction method or an electrostatic method.
前記積層機構５は、図１に示すように、ドラム機構４のドラム４１の下方に設けられた積層テーブル５１を備え、図示略の駆動モータにより上下方向や平面方向に移動する。この積層テーブル５１は、ドラム機構４のドラムにより回転搬送されてきたワークＷを順次積層する。なお、５２、５３は、積層テーブルに設けられた爪部材であり、積層されたワークＷの前端部や後端部を押さえるようになっている。 As shown in FIG. 1, the stacking mechanism 5 includes a stacking table 51 provided below the drum 41 of the drum mechanism 4, and is moved in a vertical direction or a plane direction by a drive motor (not shown). The stacking table 51 sequentially stacks the works W rotatably conveyed by the drum of the drum mechanism 4. Reference numerals 52 and 53 are claw members provided on the stacking table, and are configured to press the front end portion and the rear end portion of the stacked works W.
前記制御部６は、搬送機構１、振分機構２、移送機構３、ドラム機構４、積層機構５を各駆動モータを介して制御する。この制御部６は、図６に示すように、独立した２組の搬送機構１、振分機構２、移送機構３、ドラム機構４、積層機構５において、搬送方向に対して前方の組（図６の右側の組）の振分機構２の回転体２１と、搬送方向に対して後方の組（図６の左側の組）の振分機構２の回転体２１との回転位相が１８０度異なるように制御する。すなわち、前方の組の振分機構２の回転体２１の周面２１ａが真下を向いた姿勢となっているとき、後方の組の振分機構２の回転体２１の周面２１ａが真上を向いた姿勢となる一方、前方の組の振分機構２の回転体２１の周面２１ａが真上を向いた姿勢となっているとき、後方の組の振分機構２の回転体２１の周面２１ａが真下を向いた姿勢となる。 The control unit 6 controls the transport mechanism 1, the sorting mechanism 2, the transfer mechanism 3, the drum mechanism 4, and the stacking mechanism 5 via respective drive motors. As shown in FIG. 6, the control unit 6 includes two independent sets of a transport mechanism 1, a distribution mechanism 2, a transfer mechanism 3, a drum mechanism 4, and a stacking mechanism 5 which are arranged in front of the transport direction (see FIG. The rotation phase of the rotator 21 of the distribution mechanism 2 of the right group of 6) and the rotation body 21 of the distribution mechanism 2 of the rear group (the group on the left side of FIG. 6) in the conveying direction are different by 180 degrees. To control. That is, when the peripheral surface 21a of the rotating body 21 of the distribution mechanism 2 in the front group is in a posture facing downward, the peripheral surface 21a of the rotating body 21 of the distribution mechanism 2 in the rear group is located directly above. On the other hand, when the peripheral surface 21a of the rotating body 21 of the sorting mechanism 2 of the front set is in the posture of facing upward, the circumference of the rotating body 21 of the sorting mechanism 2 of the rear set is turned. The surface 21a is in a posture facing directly below.
而して、回転体２１は、前方の組と後方の組の間において、搬送機構１により順次搬送されている複数のワークＷを交互に下方に振り分けることができる。なお、本実施形態では、後方の組の回転体２１により奇数番目のワークＷを下方に振り分ける一方、前方の組の回転体２１により偶数番目のワークＷを下方に振り分けるものとする。 Thus, the rotating body 21 can alternately distribute the plurality of works W sequentially transported downward by the transport mechanism 1 between the front group and the rear group. In the present embodiment, the odd-numbered works W are distributed downward by the rear set of rotating bodies 21, while the even-numbered works W are distributed downward by the front set of rotating bodies 21.
次にワークＷの積層の流れについて説明する。 Next, the flow of stacking the works W will be described.
まず、搬送機構１により奇数番目のワークＷが搬送されてきた場合、図６（ａ）に示すように、該ワークＷは後方の組の回転体２１により下方に振り分けられる。そして、該ワークＷは、移送機構３により斜め下方に移送されたあと、回転ドラム機構４のドラムにより回転搬送され、積層機構５の積層テーブル５１に積層される。 First, when an odd-numbered work W is transferred by the transfer mechanism 1, the work W is sorted downward by the rear set of rotating bodies 21 as shown in FIG. 6A. Then, the work W is transferred obliquely downward by the transfer mechanism 3, then is rotationally conveyed by the drum of the rotary drum mechanism 4, and is stacked on the stacking table 51 of the stacking mechanism 5.
一方、搬送機構１により偶数番目のワークＷが搬送されてきた場合、図６（ｂ）に示すように、該シートは後方の組の回転体２１の下方を通過したあと、前方の組の回転体２１により下方に振り分けられる。そして、該ワークＷは、移送機構３により斜め下方に移送されたあと、回転ドラム機構４のドラムにより回転搬送され、積層機構５の積層テーブル５１に積層される。 On the other hand, when the even-numbered work W is transported by the transport mechanism 1, as shown in FIG. 6B, the sheet passes below the rotating body 21 of the rear group and then rotates of the front group. It is distributed downward by the body 21. Then, the work W is transferred obliquely downward by the transfer mechanism 3, then is rotationally conveyed by the drum of the rotary drum mechanism 4, and is stacked on the stacking table 51 of the stacking mechanism 5.
このように一組の振分機構２、移送機構３、ドラム機構４および積層機構５において一ないし複数のワークＷを積層したあと、他の一組の振分機構２、移送機構３、ドラム機構４および積層機構５において一ないし複数のワークＷを積層することを交互に繰り返すことによって、高速で搬送されるワークＷに対して複数組のワークＷの積層体を同時に構成するため、ワークＷを効率的に積層することができる。 After stacking one or a plurality of works W in the set of the sorting mechanism 2, the transfer mechanism 3, the drum mechanism 4, and the stacking mechanism 5, another set of the sorting mechanism 2, the transfer mechanism 3, and the drum mechanism are stacked. 4 and the stacking mechanism 5 alternately and repeatedly stacking one or a plurality of works W to form a stack of a plurality of sets of works W at the same time for the works W conveyed at high speed. It can be efficiently laminated.
なお、本実施形態では、振分機構２は、回転体２１が略半円柱状に形成されるものとしたが、その他の形状に形成されてもよい。ただ、回転体２１がワークＷに緩やかに当接するように周面２１ａの一部が曲面に形成されるのが好ましい。 In the present embodiment, the distribution mechanism 2 has the rotating body 21 formed in a substantially semi-cylindrical shape, but may be formed in other shapes. However, it is preferable that a part of the peripheral surface 21a is formed into a curved surface so that the rotating body 21 gently contacts the work W.
また、振分機構２は、回転体２１によりワークＷを下方に振り分けるものしたが、その他の機構によりワークＷを下方に振り分けるものとしてもよい。 In addition, although the distribution mechanism 2 distributes the work W downward by the rotating body 21, the work W may be distributed downward by another mechanism.
また、振分機構２とドラム機構４の間に移送機構３を設けるものとしたが、移送機構３を設けることなく、振分機構２により振り分けたワークＷをそのままドラム機構４で回転搬送してもよい。 Further, the transfer mechanism 3 is provided between the sorting mechanism 2 and the drum mechanism 4, but the work W sorted by the sorting mechanism 2 is rotatably conveyed by the drum mechanism 4 as it is without providing the transport mechanism 3. Good.
また、２組の振分機構２、移送機構３、ドラム機構４および積層機構５によってワークＷを交互に振り分けるものとしたが、３組以上の振分機構２、移送機構３、ドラム機構４および積層機構５によってワークＷを交互に振り分けてもよい。 The work W is alternately distributed by the two sets of the distribution mechanism 2, the transfer mechanism 3, the drum mechanism 4, and the stacking mechanism 5. However, three or more sets of the distribution mechanism 2, the transfer mechanism 3, the drum mechanism 4, and the The works W may be alternately distributed by the laminating mechanism 5.
また、図７に示すように、例えば４組の振分機構２、移送機構３、ドラム機構４および積層機構５を設けて、このうち２組の振分機構２、移送機構３、ドラム機構４および積層機構５によってワークＷを交互に振り分けることによって２組の積層体を構成することが完了したあと、次の２組の振分機構２、移送機構３、ドラム機構４および積層機構５によってワークＷを交互に振り分けることによって次の２組の積層体を構成してもよい。これによれば、一方の２組の積層体を構成している間に、他方の２組の積層体を別の箇所に移送することを交互に繰り返すことができ、複数組の積層体を別の工程に連続して受け渡すことが可能となる。 Further, as shown in FIG. 7, for example, four sets of the distribution mechanism 2, the transfer mechanism 3, the drum mechanism 4, and the stacking mechanism 5 are provided, and two sets of the distribution mechanism 2, the transfer mechanism 3, and the drum mechanism 4 are provided. After the two sets of stacked bodies are formed by alternately allocating the works W by the stacking mechanism 5, the next two sets of the sorting mechanism 2, the transfer mechanism 3, the drum mechanism 4, and the stacking mechanism 5 are used. The following two sets of laminated bodies may be formed by alternately allocating W.
