Description

本発明は、菓子類が収納された比較的小形・軽量な菓子容器等を、次工程の作業内容等に応じて搬送姿勢(方向性)を変換する方向転換装置に関する。   The present invention relates to a direction changing device that changes a conveying posture (direction) of a relatively small and light confectionery container or the like in which confectionery is stored in accordance with the work content of the next process.
例えば、菓子工場等において、菓子類を収納した菓子容器(物品)をダース単位で段ボール箱(カートン)に収納する場合、菓子容器の向きを揃えて収納する。
製造ラインから連続して搬出される菓子容器を、搬送工程中に向きを揃える方法として、搬送路内にガイドやストッパを配置し、このガイドやストッパに菓子容器を接触させて方向転換する方法が一般的に採用されている。しかし、この方法はガイドやストッパに物品を接触させる為、物品に衝撃が作用し、物品が損傷するという問題点を有する。
For example, in a confectionery factory or the like, when confectionery containers (articles) containing confectionery are stored in cardboard boxes (cartons) in units of dozens, the confectionery containers are stored in the same direction.
As a method of aligning the direction of the confectionery containers that are continuously carried out from the production line, there is a method in which a guide or stopper is arranged in the conveyance path and the direction is changed by bringing the confectionery container into contact with this guide or stopper. Generally adopted. However, since this method brings the article into contact with the guide or the stopper, there is a problem that an impact acts on the article and the article is damaged.
又、上記したガイドやストッパによる方向転換方式の場合、直方体のように方向性が区別できる物品において、横向きの状態(搬送方向に対し長手方向が直交する状態)から縦向きの状態(搬送方向に沿って長手方向が平行な状態)に方向転換させることはできるものの、物品が縦向きで搬送されてくる場合は、これをバラツキなく横向きの状態に安定して方向転換することは困難であるという問題点を有する。   Further, in the case of the direction changing method using the guides and stoppers described above, in a product such as a rectangular parallelepiped whose directionality can be distinguished, from a horizontal state (a state in which the longitudinal direction is perpendicular to the transport direction) to a vertical state (in the transport direction) Can be changed to a state in which the longitudinal direction is parallel), but if the article is conveyed in the vertical direction, it is difficult to stably change the direction to the horizontal state without variation. Has a problem.
そこで、上記した接触型の方向転換方式が有する問題点を解決するものとして、搬送路上にガイドやストッパ等が存在しない方向転換方式が開発提案されている。
そのものは、ローラコンベヤからなる左右少なくとも一対の対称な斜行コンベヤを相接するように配置し、左右の斜行コンベヤ間で物品の搬送速度を異ならせることにより、物品を斜行コンベヤ間の境界へと送り出す駆動力を異ならせて、物品を斜行コンベヤ間の境界で蛇行ないしは回転させるというものである(特許文献1参照)。
In order to solve the problems of the contact-type direction change method described above, a direction change method in which no guide, stopper, or the like exists on the conveyance path has been developed and proposed.
In itself, at least a pair of left and right symmetric skew conveyors consisting of roller conveyors are placed adjacent to each other, and the article conveyance speed is different between the left and right skew conveyors, thereby separating the articles between the skew conveyors. The article is meandered or rotated at the boundary between the skew conveyors by changing the driving force to be fed out (see Patent Document 1).
又、物品が跨って載ることができる並列に配列された2列の搬送コンベヤ(ローラコンベヤ、ベルトコンベヤの何れでも可)を備え、その各列の搬送コンベヤは、個別に速度制御可能な複数のコンベヤを搬送方向に縦列配置して構成し、方向転換すべき物品が搬入されると、その物品が載る範囲の左右のコンベヤの速度に速度差をつけて駆動し、方向転換するというものがある(特許文献2参照)。   Also, it is provided with two rows of conveyors arranged in parallel (both roller conveyors and belt conveyors) on which articles can be straddled, and each row of conveyors has a plurality of speed controllable individually. Conveyors are arranged in tandem in the conveyance direction, and when an article to be redirected is carried in, the speed of the left and right conveyors in the range on which the article is placed is driven with a speed difference to change direction. (See Patent Document 2).
しかし、特許文献1に記載された整列装置は、左右の斜行コンベヤの搬送速度が異なることで物品には複雑な運動が生じ、物品は境界上を蛇行ないしは回転し、左右に並んで搬送される物品の何れか一方が前方に押し出され、物品は一列に整列されるが、各物品の向きは不揃いである。即ち、特許文献1に記載の整列装置は、左右の斜行コンベヤの搬送速度に速度差をつけた状態で連続運転し、それにより左右から送り込まれる物品を境界上で蛇行、回転させて略一列に整列させるだけで、その整列される各物品の向きを一定の方向に合わせるということはできない。   However, the alignment apparatus described in Patent Document 1 causes complicated movements in the articles due to the different conveyance speeds of the left and right skew conveyors, and the articles meander or rotate on the boundary and are conveyed side by side. One of the articles to be pushed is pushed forward, and the articles are aligned in a line, but the orientation of each article is uneven. That is, the alignment apparatus described in Patent Document 1 continuously operates in a state in which the conveyance speeds of the left and right skew conveyors are different from each other, thereby causing the articles fed from the left and right to meander and rotate on the boundary to be substantially in a line. It is not possible to align the orientation of the articles to be aligned in a certain direction simply by aligning them with each other.
又、特許文献2に記載の方向転換装置は、個別に速度制御可能な複数のコンベヤを搬送方向に縦列配置し、方向転換させるべき物品が搬入されると、その物品が乗る領域の左右のコンベヤの速度に速度差をつけるもので、速度差をもった速度制御の対象とされるコンベヤ列を順次下流側に移動させる必要がある。又、方向性(向き)が不揃いで搬入される物品を、方向性を合わせる方向転換については全く記載がない。更に、左右のコンベヤの速度に速度差をつけたままだと、搬送物が方向転換しすぎる等、不安定で不統一な姿勢で下流側へ流す可能性が大きく、上流から下流側に向かって速度制御可能なコンベヤを搬送方向に縦列配置する必要があり、構成が複雑で、方向転換装置の機長も長くなるという問題点を有する。   Further, the direction changing device described in Patent Document 2 has a plurality of conveyors whose speeds can be individually controlled, arranged in tandem in the conveying direction, and when an article to be changed is carried in, the left and right conveyors in the area on which the article is placed. Therefore, it is necessary to sequentially move the conveyor row to be subjected to speed control having the speed difference to the downstream side. Moreover, there is no description at all about the direction change to match the directionality of articles that are loaded with uneven directionality (direction). Furthermore, if there is a difference in speed between the left and right conveyors, there is a high possibility that the material will flow downstream in an unstable and inconsistent posture, such as the direction of the conveyed material changing too much. It is necessary to arrange controllable conveyors in tandem in the conveying direction, and the configuration is complicated, and the length of the direction changing device becomes long.

本発明は上記した従来の技術が有する問題点に鑑みてなされたもので、その目的とするところは、物品の方向性(向き)を一定の方向に合せる方向転換を、安定して行なうことができる方向転換装置を提供することにある。
又、他の目的は搬送物に任意の回転角度をつけることができる方向転換装置を提供することにある。
更に、他の目的は機長が短くて安定した方向転換が可能な方向転換装置を提供することにある。
The present invention has been made in view of the above-described problems of the prior art, and the object of the present invention is to stably change the direction of the article so that the direction (orientation) of the article matches a certain direction. It is to provide a direction change device that can.
Another object of the present invention is to provide a direction changing device capable of giving an arbitrary rotation angle to a conveyed product.
Another object of the present invention is to provide a direction changing device that is short in length and capable of stable direction change.
上記目的を達成する為に本発明の方向転換装置は、個々に動力源を備えた複数の搬送手段を並列に配置した搬送路と、前記複数の搬送手段の搬送速度を、方向転換させる必要がある搬送物が搬入されると搬送手段の搬送速度に速度差をつけて駆動し、搬送物を方向転換させ、方向転換終了後、複数の搬送手段の搬送速度を同じ速度に戻し、方向転換後の姿勢を保持したまま搬出する速度制御手段と、を設けたことを特徴とする(請求項1)。
前記搬送路を構成する搬送手段の形態は、ローラコンベヤ、ベルトコンベヤの何れでもよく、又、並列配置する台数は、二台若しくは三台が好適である。
In order to achieve the above object, the direction changing device of the present invention needs to change the direction of the conveying path in which a plurality of conveying means each having a power source are arranged in parallel and the conveying speed of the plurality of conveying means. When a certain transported object is loaded, the transport speed of the transport means is driven with a difference in speed, the direction of the transported object is changed, and after the direction change is completed, the transport speed of a plurality of transport means is returned to the same speed, and the direction is changed. And a speed control means for carrying out the vehicle while maintaining the posture.
The form of the conveying means constituting the conveying path may be either a roller conveyor or a belt conveyor, and the number of units arranged in parallel is preferably two or three.
上記手段によれば、複数の並列配置された搬送手段に跨って供給された搬送物は、複数の搬送手段における搬送速度の速度差により方向転換(回転)される。そして、所定の方向転換が完了した後は、複数の搬送手段の搬送速度が速度差の無い同一の速度に制御されるため、搬送物は方向転換後の姿勢(方向性)を保持したまま搬出される。   According to the above means, the conveyed product supplied across the plurality of conveying means arranged in parallel is redirected (rotated) by the difference in conveying speed between the plurality of conveying means. After the predetermined direction change is completed, the transfer speeds of the plurality of transfer means are controlled to the same speed without a difference in speed, so that the transferred object is carried out while maintaining the posture (direction) after the change of direction. Is done.
前記搬送路を二台のローラコンベヤで構成し、そのコンベヤを構成する搬送ローラは夫々のコンベヤ上の搬送物が両ローラコンベヤの境界線上に集まるように傾斜配置すると共に、下流側に向かって漸次水平状態に切り替え配置し、供給された搬送物の重心が両搬送手段の境界線上に位置するようにする(請求項2)。   The transport path is composed of two roller conveyors, and the transport rollers constituting the conveyor are inclined so that the transported materials on the respective conveyors gather on the boundary line between the two roller conveyors, and gradually toward the downstream side. By switching to a horizontal state, the center of gravity of the supplied transported object is positioned on the boundary line between both transporting means (claim 2).
上記手段によれば、搬送物は両搬送手段の境界線上に集まり、搬送物の重心が該境界線上に位置することで、速度差による方向転換は安定して行なわれる。しかも、両ローラコンベヤの搬送ローラは下流側に向かって漸次水平状態に切り替え配置されているため、方向転換後の速度差を無くした同一速度による排出、乗り移りを、平行ローラによって安定よく行うことができる。   According to the above-described means, the transported objects gather on the boundary line between the both transporting means, and the center of gravity of the transported object is located on the boundary line, so that the direction change due to the speed difference is performed stably. In addition, since the transport rollers of both roller conveyors are gradually switched to the horizontal state toward the downstream side, discharge and transfer at the same speed without the speed difference after the direction change can be stably performed by the parallel rollers. it can.
前記搬送手段のローラコンベヤは、ローラ軸の両側部が軸受で支持された一般的な両端支持のコンベヤでもよいが、並列配置するローラコンベヤの対向する搬送ローラの端側が開放された片持ち支持構造とし、開放側とは反対側に磁石を利用した非接触型の駆動機構を配置した構成としてもよい(請求項3)。   The roller conveyor of the conveying means may be a general both-end supported conveyor in which both sides of the roller shaft are supported by bearings, but a cantilevered support structure in which the end sides of the opposed conveying rollers of the roller conveyors arranged in parallel are opened. In addition, a non-contact type drive mechanism using a magnet may be arranged on the side opposite to the open side (claim 3).
上記手段によれば、並列配置するローラコンベヤの境界線を挟む搬送ローラの端部を接触しないぎりぎりの位置まで近付けて配置でき、しかも各搬送ローラを駆動回転する駆動機構を磁石を利用した非接触型とすることで、前記した傾斜配置のローラ軸の駆動をスムーズに行うことができると共に、従来の他の摩擦駆動に比べ、低発塵、メンテナンスフリー、静音、及び高速運転が可能となる。   According to the above means, the end of the conveying roller sandwiching the boundary line between the roller conveyors arranged in parallel can be arranged as close as possible to the position where it does not contact, and the driving mechanism for driving and rotating each conveying roller is non-contact using a magnet. By using the mold, it is possible to smoothly drive the roller shaft having the above-described inclined arrangement, and it is possible to perform low dust generation, maintenance-free operation, silent operation, and high-speed operation as compared with other conventional friction drives.
又、前記速度制御手段としては、例えば、搬送路の上流側に設置し搬送物の搬入姿勢を検出する姿勢検出手段と、前記姿勢検出手段からの該搬送物の検出データ(搬送物の種類、方向性等)を取り込み、演算を行うメインコントローラと、該メインコントローラの演算処理で算出された速度変更指令を各搬送手段のモータに出力するモータコントローラで構成することができる(請求項4)。そして、姿勢検出手段としては、一般的にカメラを使用することができ、速度変更指令のデータとしては、各モータの回転速度、回転時間のデータ等が挙げられる(請求項5)。又、メインコントローラは、中央処理装置(CPU)、メモリ、タイマ、カウンタ等で構成し、動作プログラムはメモリに格納する。   Further, as the speed control means, for example, an attitude detection means that is installed on the upstream side of the conveyance path and detects the carry-in posture of the conveyance object, and detection data of the conveyance object from the attitude detection means (type of conveyance object, And a motor controller that outputs a speed change command calculated by the calculation process of the main controller to the motor of each conveying means (claim 4). A camera can be generally used as the posture detection means, and examples of the speed change command data include rotation speed and rotation time data of each motor. The main controller is constituted by a central processing unit (CPU), a memory, a timer, a counter, and the like, and the operation program is stored in the memory.
上記手段によれば、方向転換装置に供給される搬送物の種類と直前の姿勢(方向性)が姿勢検出手段で検出され、その検出した搬送物の種類と搬入時の姿勢に関するデータ、及び目的の方向転換後の姿勢とから、方向転換に必要な回転角度量と、回転方向(時計回り方向又は反時計回り方向)を算出し、そのデータに基づいてメインコントローラが演算処理し、両搬送手段のモータの回転速度、回転時間等のデータがモータコントローラに出力され、夫々のモータの速度が制御される。即ち、搬入直前の姿勢を検出して、目的の姿勢に方向転換するための回転角度と回転方向を算出し、それに基づき両搬送手段の回転速度と回転時間を演算処理し、そのデータをモータコントローラに送ってモータを制御する為、搬送物に任意の回転角度をつける方向転換が可能である。   According to the above means, the kind of the conveyed product supplied to the direction changing device and the immediately preceding posture (direction) are detected by the posture detecting means, and the data relating to the detected kind of the conveyed product and the posture at the time of carrying in, and the purpose The rotation angle amount necessary for the direction change and the rotation direction (clockwise direction or counterclockwise direction) are calculated from the posture after the direction change, and the main controller performs arithmetic processing based on the data, and both conveying means Data such as the motor rotation speed and rotation time are output to the motor controller, and the speed of each motor is controlled. That is, the posture immediately before carrying in is detected, the rotation angle and the rotation direction for changing the direction to the target posture are calculated, the rotation speed and the rotation time of both conveying means are calculated based on the calculated rotation angle, and the data is converted into the motor controller. Therefore, it is possible to change the direction to give an arbitrary rotation angle to the conveyed product.
また、前記搬送路を構成する搬送手段は、ベルトコンベヤで構成してもよい(請求項6)。その場合、並列配置するベルトコンベヤの台数は、二台若しくは三台とし、三台の場合は搬送物の重心が位置する真中のベルトコンベヤはベルト幅を狭くし、両側のベルトコンベヤの速度差で方向転換が行われるようにする。
更に、前記複数の搬送手段の速度差による方向転換、及び方向転換完了後の速度差を無くす速度制御は、前記した時間管理による速度制御に替えて、複数の搬送手段の境界線上に、搬送面と対向してカメラを配置し、そのカメラが撮影した画像を処理してモータの制御信号を出力するようにしてもよい(請求項7)。
Moreover, you may comprise the conveyance means which comprises the said conveyance path with a belt conveyor. In that case, the number of belt conveyors to be arranged in parallel is two or three. In the case of three belt conveyors, the belt conveyor in the middle where the center of gravity of the transported object is located has a narrow belt width, and the difference in speed between the belt conveyors on both sides. Make sure to change direction.
Further, the direction change due to the speed difference between the plurality of conveying means, and the speed control for eliminating the speed difference after the completion of the direction change, instead of the speed control based on the time management described above, on the boundary line of the plurality of conveying means, It is also possible to arrange a camera so as to face and to process an image photographed by the camera and output a motor control signal.
本発明の方向転換装置は請求項1記載の構成により、搬送物をガイド等に接触させること無く、安定した方向転換を行なうことができ、方向転換後の搬送物を安定した姿勢で、搬出コンベヤ(下流側)へ乗り移らせることができる。
そして、請求項2記載の構成とした場合は、搬送路に供給された搬送物は左右のローラコンベヤのローラの傾斜により両コンベヤの境界線上に寄せられ、搬送物の重心が前記境界線上に位置する。それにより、両コンベヤの速度差による方向転換も略重心を中心として行われ、安定した方向転換が可能となる。従って、長方形のような方向性のある搬送物が、縦向きで搬入されてくる場合でも、横向きへの方向転換をバラつきなく安定して行うことができる。
According to the direction changing device of the present invention, it is possible to perform a stable direction change without bringing the conveyed product into contact with a guide or the like according to the configuration of the first aspect. (Downstream) can be transferred.
And when it is set as the structure of Claim 2, the conveyed product supplied to the conveyance path is approached on the boundary line of both conveyors by the inclination of the roller of a right-and-left roller conveyor, and the gravity center of a conveyed product is located on the said boundary line. To do. Thereby, the direction change by the speed difference of both conveyors is also carried out centering on a substantially gravity center, and the stable direction change is attained. Therefore, even when a directional transported object such as a rectangle is carried in the vertical direction, the direction change to the horizontal direction can be stably performed without variation.
又、請求項3記載の構成とした場合は、搬送路を構成する二台のローラコンベヤの対向端を接近させて配置できるため、両コンベヤ間の隙間を最小限にでき、しかも非接触型の駆動機構により高速運転が可能で、処理能力の増大を計ることができる。
更に、請求項4、5記載の構成とした場合は、搬送物の搬入姿勢(方向性)と目的の方向転換後の姿勢(方向性)とから、方向転換に必要な回転角及び回転方向を算出し、それに基づいて両コンベヤの回転速度、運転時間を制御するため、搬送物を任意の姿勢(方向性)に方向転換することが可能である。
In the case of the configuration described in claim 3, since the opposing ends of the two roller conveyors constituting the conveyance path can be arranged close to each other, the gap between the two conveyors can be minimized, and the non-contact type High-speed operation is possible with the drive mechanism, and an increase in processing capacity can be measured.
Furthermore, when it is set as the structure of Claim 4, 5, from the carrying-in attitude | position (direction) of a conveyed product and the attitude | position (direction) after the target direction change, the rotation angle and rotation direction required for direction change are determined. Since the rotation speed and operation time of both conveyors are controlled based on the calculation, it is possible to change the direction of the conveyed product to an arbitrary posture (direction).
また、請求項6記載の構成により、ローラコンベヤからなる方向転換装置と同様、安定した方向転換を行なうことができる。
更に、請求項7記載の構成とした場合は、搬送物の姿勢を検出して速度制御を行うため、確実に方向転換を行うことができる。
Further, according to the configuration of the sixth aspect, the stable direction change can be performed as in the case of the direction change device including the roller conveyor.
Furthermore, when it is set as the structure of Claim 7, since the attitude | position of a conveyed product is detected and speed control is performed, it can change direction reliably.

It comprises a memory 5b such as a RAM for storing data and the like, a timer 5c, a counter 5d, and the like.
And this main controller 5 takes in the signal from the above-mentioned attitude | position detection means 4, performs a calculation process, and outputs a speed change command to the motor controllers 6 and 6 '.
The speed change command is data such as the rotation speed and rotation time of the motor 2d.
モータコントローラ6,6’は、搬送路A1を構成する二台のローラコンベヤ1,1’にそれぞれ装備されているモータ2dの速度を個々に制御するもので、マイクロコンピュータ及びモータ駆動回路を内蔵する。マイクロコンピュータは、中央処理装置(CPU)、メモリ、カウンタを備え、メモリには方向転換処理用のプログラムデータが記憶されており、中央処理装置(CPU)はメモリに記憶された前記プログラムデータに基づいてモータ駆動回路を介してモータ2dを速度制御する。そして、搬送物Wの回転角度量に応じて両コンベヤ1,1’の速度差が決定される。
速度差は、二台のローラコンベヤ1,1’の搬送速度に速度差をつけないときの標準速度Vに対し、二台のローラコンベヤ1,1’の搬送速度をそれぞれV+α,V、或いはV+α,V−α、V−α,V(但し、0≦α)等、設定することができる。尚、標準速度Vに対してプラス・マイナスするα値は同一の値、或いは異なる値でもよい。α値を同じとした場合は、搬送物相互の中心間距離を一定に保って方向転換、搬送することができる。又、一方のコンベヤの搬送速度を標準速度Vに固定し、他方のコンベヤの搬送速度をV+αまたはV−αとする場合、α値は搬送物Wの重量、大きさ等に応じて決定される。
The motor controllers 6 and 6 'individually control the speeds of the motors 2d provided in the two roller conveyors 1 and 1' constituting the conveyance path A1, and incorporate a microcomputer and a motor drive circuit. . The microcomputer includes a central processing unit (CPU), a memory, and a counter. Program data for direction change processing is stored in the memory, and the central processing unit (CPU) is based on the program data stored in the memory. The speed of the motor 2d is controlled via the motor drive circuit. And the speed difference of both conveyors 1 and 1 'is determined according to the rotation angle amount of the conveyed product W.
For the speed difference, the transport speed of the two roller conveyors 1, 1 'is V + α, V, or V + α, respectively, with respect to the standard speed V when no difference is made in the transport speed of the two roller conveyors 1, 1'. , V-α, V-α, V (where 0 ≦ α), etc. can be set. It should be noted that the α value to be plus or minus with respect to the standard speed V may be the same value or a different value. When the α value is the same, the direction can be changed and transported while keeping the distance between the centers of the transported objects constant. In addition, when the conveyance speed of one conveyor is fixed at the standard speed V and the conveyance speed of the other conveyor is V + α or V−α, the α value is determined according to the weight, size, etc. of the conveyed product W. .
前記姿勢検出手段4が配置される搬入コンベヤBは、図1及び図2に示すように二台のベルトコンベヤ7,7’を縦一列に連設配置して構成され、そうした搬入コンベヤBが幅方向の中心を方向転換装置Aにおける搬送路A1の幅方向の中心線(二台のローラコンベヤ1,1’の境界線)上に合せて配置されている、それにより、搬送物Wは方向転換装置Aの搬送路A1を構成する二台のローラコンベヤ1,1’に跨って載せられる。そして、方向転換装置Aの手前側に位置するベルトコンベヤ7の上方に前記姿勢検出手段4のカメラが設置されている。   As shown in FIGS. 1 and 2, the carry-in conveyor B on which the posture detecting means 4 is arranged is configured by arranging two belt conveyors 7 and 7 'in a row in a row, and the carry-in conveyor B has a width. The center of the direction is arranged on the center line in the width direction of the conveyance path A1 in the direction changing device A (the boundary line between the two roller conveyors 1 and 1 '). It is placed across the two roller conveyors 1, 1 ′ constituting the conveying path A 1 of the apparatus A. And the camera of the said attitude | position detection means 4 is installed above the belt conveyor 7 located in the near side of the direction change apparatus A. FIG.
又、二台のベルトコンベヤ7,7’の連設箇所の側方には搬送物Wの有無を検出するセンサ8が設置されており、これによりベルトコンベヤ7,7’の作動が制御され、搬送物Wの搬送間隔が調整されるようになっている。即ち、方向転換装置Aの搬送路A1内に搬送物Wが同時に複数個載らないように調整される。又、前記センサ8は、高さの異なる搬送物Wでも検出できるように、鉛直方向に所定の間隔をおいて複数個(図面では2個を示す)設置されている。尚、搬入コンベヤBはベルトコンベヤに限らず、ローラコンベヤでもよい。又、方向転換装置Aにおける搬送路A1の幅方向中央線上に搬送物Wの重心を合致させて搬入する手段として、搬入コンベヤ上に搬送方向を規制するガイド等を設けて行うようにしてもよい。   In addition, a sensor 8 for detecting the presence or absence of the transported object W is installed on the side of the connected portion of the two belt conveyors 7 and 7 ', thereby controlling the operation of the belt conveyors 7 and 7'. The conveyance interval of the conveyed product W is adjusted. That is, it is adjusted so that a plurality of transported articles W are not placed on the transport path A1 of the direction changing device A at the same time. In addition, a plurality of sensors 8 (two are shown in the drawing) are installed at a predetermined interval in the vertical direction so as to be able to detect a conveyed product W having a different height. The carry-in conveyor B is not limited to a belt conveyor but may be a roller conveyor. Moreover, as a means for bringing the center of gravity of the conveyed product W on the center line in the width direction of the conveyance path A1 in the direction changing device A, a guide or the like for regulating the conveyance direction may be provided on the carry-in conveyor. .
次に、前記した方向転換装置Aの動作を図5に基づいて説明する。本実施例では、長方形の搬送物Wを縦向きで搬入し、これを時計回り方向に90度回転させて横向きに方向転換する場合について説明する。尚、長方形の搬送物Wの方向性を示す為に、搬送物Wの頭側には斜線を表示する。
(a):方向転換装置Aの上流側に配置した搬入コンベヤBで、搬送物Wの搬送間隔が調整され、且つ方向転換装置Aの搬送路A1の幅方向略中央部に搬入される。そして、この搬入コンベヤBのベルトコンベヤ7を通過する際、上方に設置した姿勢検出手段4のカメラで搬送物Wが撮影され、搬送物Wの種類、方向性(頭側が先か後か)が検出される。
Next, the operation of the direction changing device A will be described with reference to FIG. In the present embodiment, a description will be given of a case where a rectangular conveyed product W is carried in a vertical direction, and is rotated 90 degrees clockwise to change the direction horizontally. In addition, in order to show the directionality of the rectangular conveyed product W, a diagonal line is displayed on the head side of the conveyed product W.
(A): The conveyance interval of the conveyed product W is adjusted by the carry-in conveyor B arranged on the upstream side of the direction changing device A, and is carried into the center in the width direction of the conveyance path A1 of the direction changing device A. And when passing the belt conveyor 7 of this carrying-in conveyor B, the conveyed product W is image | photographed with the camera of the attitude | position detection means 4 installed upwards, and the kind and directionality (head side is front or back) of the conveyed product W are shown. Detected.
(b):方向転換装置Aに搬入される搬送物Wに関するデータが速度制御手段A2のメインコントローラ5に入力されると、メインコントローラ5はメモリ5bに記憶してある搬送物Wに関するデータを読み出し、方向転換の可否を判断し、搬送物Wが方向転換させる必要の無いものである場合は、方向転換装置Aの搬送路A1を構成する二台のローラコンベヤ1,1’の搬送速度を同じ速度とするよう、夫々のコンベヤ1,1’のモータコントローラ6,6’に信号を出力する。そして、モータコントローラ6,6’の制御でローラコンベヤ1,1’の各モータ2dは同じ回転速度に制御される。それにより、方向転換の必要のない搬送物Wは、重心を略両コンベヤ1,1’の境界線上に位置させた状態で、搬入された方向性を維持してそのまま下流側に搬送され、搬出コンベヤCに排出される。尚、方向転換装置Aの二台のローラコンベヤ1,1’は夫々のコンベヤの搬送ローラ1aが搬送物の重心が境界線上に寄るように傾斜されている為、方向転換装置Aに搬入される搬送物はセンタリングされて搬送される。 (B): When the data related to the conveyed product W carried into the direction changing device A is input to the main controller 5 of the speed control means A2, the main controller 5 reads the data related to the conveyed product W stored in the memory 5b. In the case where it is not necessary to change the direction of the transported object W, the transport speeds of the two roller conveyors 1, 1 ′ constituting the transport path A1 of the direction changing device A are the same. Signals are output to the motor controllers 6 and 6 'of the respective conveyors 1 and 1' so that the speed is obtained. The motors 2d of the roller conveyors 1 and 1 'are controlled at the same rotational speed under the control of the motor controllers 6 and 6'. As a result, the transported object W that does not need to change its direction is transported downstream as it is while maintaining the directionality of the transported object, with the center of gravity positioned substantially on the boundary line between the two conveyors 1 and 1 '. It is discharged to the conveyor C. The two roller conveyors 1, 1 ′ of the direction changing device A are carried into the direction changing device A because the conveying rollers 1a of the respective conveyors are inclined so that the center of gravity of the conveyed product is on the boundary line. The conveyed product is centered and conveyed.
(c):方向転換装置Aに搬入される搬送物Wが方向転換させる必要があるものとメインコントローラ5で判断されると、該メインコントローラ5に入力されたデータに基づいて演算処理を行い、搬送物Wを所定の姿勢に方向転換させるための回転角度量と、回転方向を算出し、それに基づいて二台のローラコンベヤ1,1’の搬送速度に速度差をつける演算処理が行われ、それぞれのローラコンベヤ1,1’のモータ2dを制御するモータコントローラ6,6’に回転速度、回転時間等のデータが出力される。即ち、方向転換装置Aの始端側から終端側に向かって所定距離の位置に搬送物Wが到達したら速度差をつけた運転が行われ、その速度差運転時間経過後は同速運転に戻す。それにより、二台のローラコンベヤ1,1’が速度差をつけて駆動し、搬送物Wは回転される。図示の実施例では、目的の姿勢が搬送物Wの頭側が搬送方向に向かって右側となる横向きであるため、搬送物Wを時計回り方向に90度回転させなければならない。その為、搬送物Wを回転させる速度差運転は、搬送方向に向かって右側のローラコンベヤ1の搬送速度を標準速度Vに固定し、左側のローラコンベヤ1’の搬送速度をV+αとすることで、搬送物Wは両コンベヤ1,1’の境界線上に位置する重心(O)を中心として回転し、予め設定された速度差運転の時間経過で搬送物Wは目的の姿勢に方向転換される。尚、図示は目的の方向転換する姿勢が右横向きであるため時計回り方向の回転について説明したが、目的の方向転換の姿勢が左横向きである場合は、搬送方向に向かって左側のローラコンベヤ1’の速度を標準速度Vに固定し、右側のローラコンベヤ1の搬送速度をV+αとすることで、反時計回り方向の回転で方向転換される。即ち、目的の姿勢と搬入時の姿勢とから、最も効率良く方向転換できる方向が決定され、それに基づいて速度制御が行われる。 (C): When the main controller 5 determines that the conveyed product W carried into the direction changing device A needs to be changed in direction, an arithmetic process is performed based on the data input to the main controller 5; A rotation angle amount for changing the direction of the conveyed product W to a predetermined posture and a rotation direction are calculated, and based on the calculation processing, a speed difference is performed between the conveyance speeds of the two roller conveyors 1 and 1 ′. Data such as rotation speed and rotation time is output to the motor controllers 6 and 6 ′ that control the motors 2d of the respective roller conveyors 1 and 1 ′. That is, when the conveyed product W reaches a position at a predetermined distance from the start end side to the end end side of the direction changing device A, an operation with a speed difference is performed, and the operation is returned to the same speed operation after the speed difference operation time has elapsed. As a result, the two roller conveyors 1 and 1 ′ are driven with a speed difference, and the conveyed product W is rotated. In the illustrated embodiment, the target posture is a horizontal orientation in which the head side of the conveyed product W is on the right side in the conveying direction, and therefore the conveyed product W must be rotated 90 degrees in the clockwise direction. Therefore, the speed difference operation for rotating the conveyed product W is performed by fixing the transport speed of the right roller conveyor 1 to the standard speed V in the transport direction and setting the transport speed of the left roller conveyor 1 ′ to V + α. The transported object W rotates around the center of gravity (O) located on the boundary line between the two conveyors 1 and 1 ', and the transported object W is turned to a target posture after a predetermined speed difference operation. . In the drawing, the rotation in the clockwise direction has been described because the target direction changing posture is right sideways. However, when the target direction changing posture is left sideways, the roller conveyor 1 on the left side in the conveying direction is illustrated. The speed of 'is fixed to the standard speed V, and the conveyance speed of the right roller conveyor 1 is set to V + α, so that the direction is changed by the counterclockwise rotation. That is, the direction in which the direction can be changed most efficiently is determined from the target posture and the posture at the time of carrying in, and speed control is performed based on the direction.
(d):方向転換装置Aを構成する二台のローラコンベヤ1,1’を速度差をつけて駆動し、所定時間経過により方向転換が完了すると二台のローラコンベヤ1,1’の速度差は解除され、二台のローラコンベヤ1,1’の搬送速度は同じ速度Vに制御される。それにより、方向転換された搬送物Wは、その方向転換後の姿勢を維持したまま同じ速度で駆動する二台のローラコンベヤ1,1’で下流側に搬送され、搬出コンベヤCに排出される。 (D): The two roller conveyors 1, 1 'constituting the direction changing device A are driven with a speed difference, and when the direction change is completed after a predetermined time, the speed difference between the two roller conveyors 1, 1' Is released, and the conveying speeds of the two roller conveyors 1, 1 'are controlled to the same speed V. Thereby, the conveyed product W whose direction has been changed is conveyed downstream by the two roller conveyors 1 and 1 ′ driven at the same speed while maintaining the posture after the direction change, and is discharged to the carry-out conveyor C. .
図6は、方向転換装置A’を構成する搬送路A1を、二台のベルトコンベヤ9,9’で構成した形態を示し、その二台のベルトコンベヤ9,9’は対向するベルトの内側端を接触しない範囲で接近させて並列配置されている。そして、夫々のコンベヤ9,9’に装備されたモータ10は前示実施例と同様、速度制御手段A2によって個々に速度制御され、方向転換させる必要がある搬送物Wは、両コンベヤ9,9’の速度差運転、及び方向転換後の同速運転により、方向転換されて排出される。
尚、ベルトコンベヤ9,9’の場合は、前示実施例におけるローラコンベヤ1,1’と比べて摩擦抵抗が大きい為、搬送物Wの重心Oが両コンベヤ9,9’の境界線上に位置するように搬入することが必要である。その為に、上流側に配置する搬入コンベヤBに搬入の方向を規制するガイド等を配置すると有効である。
FIG. 6 shows a form in which the conveying path A1 constituting the direction changing device A ′ is constituted by two belt conveyors 9 and 9 ′, and the two belt conveyors 9 and 9 ′ are the inner ends of the opposed belts. Are arranged in parallel so that they are close to each other without contact. Similarly to the previous embodiment, the speeds of the motors 10 mounted on the respective conveyors 9 and 9 'are individually controlled by the speed control means A2, and the conveyed product W that needs to be changed in direction is transferred to both the conveyors 9 and 9. The direction is changed and discharged by the speed difference operation of 'and the same speed operation after the direction change.
In the case of the belt conveyors 9 and 9 ', the frictional resistance is larger than that of the roller conveyors 1 and 1' in the previous embodiment, so that the center of gravity O of the conveyed product W is positioned on the boundary line between the two conveyors 9 and 9 '. It is necessary to carry in. Therefore, it is effective to arrange a guide or the like for restricting the direction of loading on the loading conveyor B arranged on the upstream side.
上記方向転換装置A’は、ベルトコンベヤ9,9’を二台並列配置して構成した形態を示したが、搬送路A1の幅方向中央部に細幅のベルトコンベヤを配置し、その両脇にベルトコンベヤ9,9’を並列配置して構成してもよい。この場合は、中央の細幅のベルトコンベヤ内に搬送物の重心を位置させて搬送し、方向転換させる。   The direction changing device A ′ has a configuration in which two belt conveyors 9 and 9 ′ are arranged in parallel. A narrow belt conveyor is arranged at the center in the width direction of the conveying path A1, and both sides thereof are arranged. The belt conveyors 9 and 9 'may be arranged in parallel. In this case, the center of gravity of the conveyed product is positioned in a narrow belt conveyor at the center, and the direction is changed.
本発明の方向転換装置は、上記したように搬送路A1に搬送物Wが完全に乗り移った時点で速度差運転による方向転換を行い、所定の姿勢に方向転換が完了した後、速度差運転を解除して同速運転を行うため、方向転換を安定して行なうことができると共に、方向転換後の姿勢を維持したまま搬送排出することができる。   As described above, the direction changing device of the present invention performs the direction change by the speed difference operation when the transported object W has completely transferred to the transfer path A1, and after the direction change is completed to the predetermined posture, the speed difference operation is performed. Since the same speed operation is performed after the release, the direction change can be performed stably and the sheet can be conveyed and discharged while maintaining the posture after the direction change.
本発明の方向転換装置は、並列配置したコンベヤ相互の速度差を利用して搬送物を回転させ、所定の方向転換をさせた後はコンベヤ相互の速度差を無くして同速運転し、方向転換後の姿勢(方向性)を維持したまま搬送できるため、商品を方向性を揃えて箱詰する生産ラインに有効である。   The direction changing device of the present invention uses the speed difference between the conveyors arranged in parallel to rotate the conveyed product, and after the predetermined direction change, eliminates the speed difference between the conveyors and operates at the same speed to change the direction. Since it can be conveyed while maintaining the subsequent posture (direction), it is effective for a production line that packs products with the same directionality.
