Description

本発明は、選別装置に関し、特に物品検査された複数の物品を選別搬送コンベアにより並列搬送しつつ選別動作する選別装置に関する。   The present invention relates to a sorting apparatus, and more particularly to a sorting apparatus that performs a sorting operation while conveying a plurality of articles that have been inspected by a sorting and conveying conveyor in parallel.

従来、各種物品を搬送中に検査する物品検査装置、例えば金属異物検出装置、X線異物検査装置、重量計測装置等において、コンベアに複数の物品を並列に投入したり並列する搬送レーンを設定したりして搬送中の複数の物品を略同時に検査できるようにすることで、省スペース化や検査の効率化を図ったものがある(例えば、特許文献1、2、3参照)。   Conventionally, in an article inspection apparatus that inspects various articles while transporting, for example, a metal foreign object detection apparatus, an X-ray foreign object inspection apparatus, a weight measurement apparatus, etc., a transport lane is set in which a plurality of articles are placed in parallel or parallel. In some cases, a plurality of articles being conveyed can be inspected substantially simultaneously, thereby saving space and improving the efficiency of inspection (for example, see Patent Documents 1, 2, and 3).

そして、そのような物品検査装置による検査後に並列搬送される物品を、それぞれの検査結果に応じた搬送先に振り分けることができる選別装置が多用されている。   A sorting apparatus that can distribute articles conveyed in parallel after inspection by such an article inspection apparatus to a conveyance destination corresponding to each inspection result is frequently used.

この種の選別装置としては、例えば並列する選別搬送コンベアの複数のコンベアベルトやプーリをモータ駆動される共通の駆動軸に同期駆動可能に結合した多連結合型のものが知られており、この装置では、1連(各列)ごとに選別搬送コンベアを上下方向に揺動させる駆動シリンダが設けられている(例えば、特許文献4参照)。   As this type of sorting apparatus, for example, a multiple coupling type is known in which a plurality of conveyor belts and pulleys of sorting conveyors arranged in parallel are coupled to a common drive shaft driven by a motor so that they can be driven synchronously. The apparatus is provided with a drive cylinder that swings the sorting and conveying conveyor in the vertical direction for each series (each row) (see, for example, Patent Document 4).

このような選別装置においては、選別装置による選別搬送区間を通過する物品の搬送速度(搬送距離/搬送時間)は、通常、選別装置の前段側および後段側の物品搬送速度に合わせた速度に設定されている。   In such a sorting apparatus, the conveyance speed (conveyance distance / conveyance time) of articles passing through the sorting conveyance section by the sorting apparatus is usually set to a speed that matches the article conveyance speed on the front side and the rear stage side of the sorting apparatus. Has been.

上述のような従来の選別装置にあっては、上流側での物品投入時やその後の搬送中に搬送物品にスリップが生じることで、選別装置への物品の投入タイミングが並列する選別搬送コンベア間で不規則にずれる場合がある。   In the conventional sorting apparatus as described above, a slip occurs in the conveyed article when the article is loaded on the upstream side or during the subsequent conveyance, so that the timing of loading the article into the sorting apparatus is parallel between the sorting and conveying conveyors. May shift irregularly.

また、検査装置より上流側での処理(例えば容器内への内容物の充填)を行うタイミングや投入距離が搬送レーン間でわずかにずれることにより、検査装置での略同時の物品検査が可能な範囲内ではあるものの、並列搬送により略同期搬送される物品が選別装置に投入されるタイミングが規則的にずれる場合もある。   In addition, when the processing (for example, filling the contents in the container) on the upstream side of the inspection apparatus and the input distance are slightly shifted between the transfer lanes, it is possible to inspect the articles almost simultaneously with the inspection apparatus. Although within the range, the timing at which articles that are substantially synchronously conveyed by parallel conveyance are thrown into the sorting apparatus may be regularly shifted.

しかしながら、従来の選別装置では、並列搬送される物品間に搬送タイミングのずれがあっても、そのタイミングを揃えることができないという問題があった。   However, the conventional sorting apparatus has a problem in that even if there is a shift in the conveyance timing between the articles conveyed in parallel, the timing cannot be aligned.

そのため、後段に包装機等(例えば箱詰めのための包装機)が設置される場合に、並列搬送される物品を後段側に適時に搬出することができないという問題があった。   For this reason, when a packaging machine or the like (for example, a packaging machine for boxing) is installed in the subsequent stage, there is a problem that the articles conveyed in parallel cannot be carried out to the subsequent stage in a timely manner.

本発明は、かかる従来の問題を解消するものであり、並列する選別搬送コンベアへの前段からの搬入タイミングにずれがあったとしても、確実な選別動作と後段側への適時の搬出が可能な選別装置を提供することを目的とする。   The present invention solves such a conventional problem, and even if there is a shift in the timing of carrying in from the preceding stage to the sorting and conveying conveyors arranged in parallel, a reliable sorting operation and timely delivery to the subsequent stage are possible. An object is to provide a sorting device.

A sorting drive actuator 27 that swings the shaft support frame 26 in the vertical direction is interposed between the intermediate portion of the shaft support frame 26 and the support 4.

この選別駆動アクチュエータ27は、例えば支持体4に対し図4中の左右方向に揺動可能に支持されたエアシリンダで構成されており、その作動流体であるエアの給排(圧搾空気の供給および排出)を制御することで、伸長および収縮動作可能となっている。また、選別駆動アクチュエータ27は、選別駆動制御部41によって図外の圧空源(動力源)からのエアの給排を制御されるようになっている。   The sorting drive actuator 27 is composed of, for example, an air cylinder supported so as to be swingable in the left-right direction in FIG. 4 with respect to the support 4, and supply / discharge of air as the working fluid (supply of compressed air and By controlling (discharge), extension and contraction operations are possible. The sorting drive actuator 27 is controlled by the sorting drive control unit 41 to supply and discharge air from a non-illustrated compressed air source (power source).

軸支持フレーム26および選別駆動アクチュエータ27は、物品Wの検査結果に応じた選別のために搬送先の振分け動作を行う振分け機構28を構成している。   The shaft support frame 26 and the sorting drive actuator 27 constitute a sorting mechanism 28 that performs a sorting operation of the transport destination for sorting according to the inspection result of the article W.

この振分け機構28は、計量コンベア1上で物品検査である重量計測がなされて選別搬送区間Z内に搬入された物品Wを、図2および図4に示す複数の振分け方向D1、D2のうち検査結果に対応するいずれかの方向に方向付けて、選別搬送区間Zから搬出(搬送経路外への排出を含む)する振分け動作を実行するようになっている。すなわち、振分け機構28は、物品Wが選別搬送区間Z内に搬入されたとき、その物品Wを複数の振分け方向のうちその物品Wの検査結果に対応するいずれかの方向に方向付けるように方向選択して、その物品Wを選択した振分け方向に搬出させる振分け動作を実行するようになっている。   The distribution mechanism 28 inspects an article W that has been subjected to weight measurement, which is an article inspection, on the weighing conveyor 1 and is carried into the sorting conveyance section Z, among a plurality of distribution directions D1 and D2 shown in FIGS. A sorting operation is performed in which the direction is directed in any direction corresponding to the result, and is carried out from the sorting conveyance section Z (including discharge outside the conveyance path). That is, when the article W is carried into the sorting and conveying section Z, the distribution mechanism 28 directs the article W in one of a plurality of distribution directions corresponding to the inspection result of the article W. A sorting operation for selecting and carrying out the article W in the selected sorting direction is executed.

また、振分け機構28は、計量コンベア1側からの選別信号入力を待つ運転中の待機時に、物品Wを複数の振分け方向のうち特定の振分け方向に振り分ける姿勢、例えば図2に実線で示すように良品の通過が可能な待機姿勢をとるように構成されている。   In addition, the distribution mechanism 28 is configured to distribute the article W in a specific distribution direction among a plurality of distribution directions, for example, as indicated by a solid line in FIG. It is configured to take a stand-by posture in which non-defective products can pass.

選別駆動制御部41は、詳細を図示しないが、例えば選別駆動アクチュエータ27へのエアの給排を制御する電磁切換え弁と、その電磁切換え弁の作動を制御するプログラマブルコントローラ等を含んで構成されており、計量コンベア1の制御部13からの選別信号RJと予め設定された選別駆動条件に従って、選別駆動アクチュエータ27により、選別搬送コンベア2を、図4中に実線およびD1方向で示す前述の待機姿勢としての第1姿勢と同図中に仮想線およびD2方向で示す不良品排出可能な第2姿勢とに変化させ、搬送先を振り分け得るようになっている。   Although not shown in detail, the sorting drive control unit 41 includes, for example, an electromagnetic switching valve that controls supply / discharge of air to / from the sorting drive actuator 27 and a programmable controller that controls the operation of the electromagnetic switching valve. In accordance with the sorting signal RJ from the control unit 13 of the weighing conveyor 1 and preset sorting driving conditions, the sorting and driving actuator 27 causes the sorting and conveying conveyor 2 to be in the above-described standby posture indicated by the solid line and the D1 direction in FIG. The first posture is changed to the second posture in which the defective product can be discharged as indicated by the imaginary line and the D2 direction in FIG.

選別搬送コンベア2は、第1姿勢をとるとき、前段の計量コンベア1から搬入される物品Wを搬入方向と同じD1方向に搬送して後段コンベア3側に受渡すことができる。また、選別搬送コンベア2は、第2姿勢をとるとき、前段の計量コンベア1から搬入される物品Wを後段コンベア3側への正常搬送経路から外れるD2方向に向けて図4中の下方側に排出し、図示しない受け箱等に収容することができる。   When the sorting and conveying conveyor 2 takes the first posture, it can convey the article W carried in from the preceding weighing conveyor 1 in the same D1 direction as the loading direction and deliver it to the subsequent conveyor 3 side. In addition, when the sorting and conveying conveyor 2 takes the second posture, the article W carried from the preceding weighing conveyor 1 is directed downward in FIG. 4 toward the direction D2 that deviates from the normal conveying path to the latter conveying 3 side. It can be discharged and stored in a receiving box (not shown).

すなわち、選別駆動制御部41は、計量コンベア1の制御部13(上位の物品検査装置)からの指令信号に従って振分け機構28の作動を制御するようになっている。   That is, the sorting drive control unit 41 controls the operation of the sorting mechanism 28 in accordance with a command signal from the control unit 13 (upper article inspection apparatus) of the weighing conveyor 1.

物品検知センサ29は、例えば計量コンベア1から選別搬送コンベア2に物品Wが受け渡され、選別搬送コンベア2に投入される位置に、あるいは、それより上流側に設置されている。この物品検知センサ29の物品検知信号は、制御部13に取り込まれるようになっており、制御部13により、選別搬送コンベア2上にあるいは計量コンベア1上に物品Wが存在するか否かを判定することができる。なお、物品検知センサ29は、計量コンベア1で用いる物品検知センサを共用するようにしてもよい。   The article detection sensor 29 is installed, for example, at a position where the article W is delivered from the weighing conveyor 1 to the sorting and conveying conveyor 2 and is put into the sorting and conveying conveyor 2 or upstream thereof. The article detection signal of the article detection sensor 29 is taken into the control unit 13, and the control unit 13 determines whether or not the article W exists on the sorting and conveying conveyor 2 or on the weighing conveyor 1. can do. Note that the article detection sensor 29 may share the article detection sensor used in the weighing conveyor 1.

計量コンベア1の制御部13は、具体的なハードウェア構成を図示しないが、例えばCPU、ROM、RAM、及び入出力インターフェース回路等を含んで構成されており、ROMや他のメモリデバイスに格納された所定の計量(秤量)制御プログラムや重量選別のための搬送および振分けの制御プログラム等に従って、計量コンベア1の作動を制御するとともに、選別駆動制御部41と協働して選別搬送コンベア2の作動を制御するようになっている。   The control unit 13 of the weighing conveyor 1 is not shown in a specific hardware configuration, but includes, for example, a CPU, a ROM, a RAM, an input / output interface circuit, and the like, and is stored in the ROM or other memory device. The operation of the weighing conveyor 1 is controlled in accordance with a predetermined weighing (weighing) control program, a conveyance and distribution control program for weight sorting, and the operation of the sorting conveyor 2 in cooperation with the sorting drive control unit 41. Is to control.

この制御部13は、前述の各種制御プログラムを実行することで、計量コンベア1による検査を制御する検査制御部31と、選別搬送コンベア2の選別動作を指令信号により制御する選別制御部32と、各種設定値や検査条件、品種情報、検査結果、来歴等を記憶する記憶部33との機能を発揮するように構成されている。また、制御部13には、検査結果その他の各種情報を表示する表示部35と、各種設定値その他の手動操作入力が可能な入力部36とが併設されている。   The control unit 13 executes the above-described various control programs to thereby control the inspection control unit 31 that controls the inspection by the weighing conveyor 1, the sorting control unit 32 that controls the sorting operation of the sorting and conveying conveyor 2 by a command signal, It is configured to exhibit the function of the storage unit 33 that stores various set values, inspection conditions, product type information, inspection results, history, and the like. Further, the control unit 13 is provided with a display unit 35 for displaying inspection results and other various information, and an input unit 36 capable of inputting various set values and other manual operations.

検査制御部31は、予め設定された品種ごとの設定パラメータや自機の仕様(例えば選別搬送区間Zの長さに対応する機長)に応じて計量コンベア1の作動を制御するとともに、計量コンベア1の計量部11による計量値の算出処理や、検査結果となる重量値の合否判定処理等を実行するようになっている。   The inspection control unit 31 controls the operation of the weighing conveyor 1 according to the preset setting parameters for each product type and the specifications of the own machine (for example, the machine length corresponding to the length of the sorting and conveying section Z), and the weighing conveyor 1 The measurement value calculation process by the weighing unit 11 and the weight value pass / fail determination process as the inspection result are executed.

選別制御部32は、選別搬送コンベア2の搬送モータ21を駆動する搬送駆動信号や物品Wごとの検査結果に対応する選別信号を生成して、選別信号に対応する検査済みの物品Wが選別搬送区間Z内に到達するタイミングでその選別信号を選別駆動制御部41に出力し、その物品Wが選別搬送区間Z内に搬入されてから後段コンベア3に受け渡されるまでの期間中、搬送モータ21の速度および選別駆動アクチュエータ27の作動を選別駆動制御部41により制御させる選別搬送要求信号Mcおよび選別信号RJを出力できるようになっている。また、選別制御部32は、後述する特定列の搬出タイミングを選別搬送コンベア2の搬送速度制御により揃える搬出タイミング制御を実行するモードと実行しないモードとの切替えやその制御条件を品種に応じて設定できるようになっている。   The sorting control unit 32 generates a sorting signal corresponding to the inspection driving result for each article W and a conveyance driving signal for driving the conveyance motor 21 of the sorting conveyance conveyor 2, and the inspected article W corresponding to the sorting signal is sorted and conveyed. The sorting signal is output to the sorting drive control unit 41 at the timing of reaching the section Z, and the transport motor 21 is in a period from when the article W is carried into the sorting transport section Z until it is delivered to the subsequent conveyor 3. The sorting transport request signal Mc and the sorting signal RJ that allow the sorting drive control unit 41 to control the speed and the operation of the sorting drive actuator 27 can be output. In addition, the sorting control unit 32 switches between a mode for executing the carry-out timing control for aligning the carry-out timing for a specific row, which will be described later, by carrying speed control of the sorting and conveying conveyor 2 and a mode for not executing it, and sets the control conditions according to the type. It can be done.

記憶部33は、前述のROMや他のメモリデバイスで構成され、例えば自機の仕様から定まる固定された設定パラメータを記憶するとともに、物品となる物品Wの品種ごとの生産速度(搬送速度)や許容重量範囲、その他の検査条件、前述の搬出タイミング制御等が設定されたとき、それらの設定値情報を記憶するようになっている。   The storage unit 33 is composed of the above-described ROM or other memory device, and stores fixed setting parameters determined based on the specifications of the own machine, for example, and the production speed (conveying speed) for each type of article W as an article. When the allowable weight range, other inspection conditions, the above-described carry-out timing control, and the like are set, the set value information is stored.

このような制御部13において、選別信号RJは、検査結果信号がNG信号であって振分け機構28を第1姿勢から第2姿勢に移行させる必要があるときに立ち上がるようになっている。   In such a control unit 13, the selection signal RJ rises when the inspection result signal is an NG signal and the distribution mechanism 28 needs to be shifted from the first posture to the second posture.

もっとも、検査結果に対応する振分け方向をD1方向およびD2方向の2方向にするのでなく、例えば重量超過物品と重量不足物品を分けるよう3方向にしたり、ランク分けのためにより多くの振分け方向を設定したりする場合には、選別搬送区間Zを搬送方向に隣り合う複数の選別搬送コンベアによって形成し、下流側の第2姿勢の選別搬送コンベアでの不良品排出のために上流側の選別搬送コンベアを第1姿勢に維持するようなことは可能である。また、第1姿勢と第2姿勢の間での姿勢変化ごとに振分信号を発生させて、双方向の振分け動作をアクチュエータ駆動することや、3つ以上の搬送先に対応する多方向の振分け動作を行うべく複数種の選別信号を生成することも可能である。   However, the distribution direction corresponding to the inspection result is not set to the two directions of the D1 direction and the D2 direction. For example, the distribution direction is divided into three directions so as to separate overweight articles and underweight articles, or more distribution directions are set for ranking. The sorting and conveying section Z is formed by a plurality of sorting and conveying conveyors adjacent to each other in the conveying direction, and the upstream sorting and conveying conveyor is used for discharging defective products on the sorting and conveying conveyor in the second posture on the downstream side. Can be maintained in the first posture. In addition, a distribution signal is generated for each posture change between the first posture and the second posture, and the bi-directional distribution operation is driven by an actuator, and multi-directional distribution corresponding to three or more transport destinations is performed. It is also possible to generate a plurality of types of sorting signals to perform the operation.

一方、選別駆動制御部41は、前述のように選別制御部32からの指令信号に従って、選別信号RJに応じ振分け機構28の動作を制御するとともに、選別搬送要求信号Mcに応じ搬送モータ21による選別搬送コンベア2の選別搬送速度を可変制御する、第1のコントローラ機能を有している。   On the other hand, the sorting drive control unit 41 controls the operation of the sorting mechanism 28 according to the sorting signal RJ according to the command signal from the sorting control unit 32 as described above, and the sorting by the transport motor 21 according to the sorting transport request signal Mc. A first controller function for variably controlling the sorting and conveying speed of the conveyor 2 is provided.

選別駆動制御部41は、また、選別制御部32から切り離されたときでも、自機の列ごとの物品検知センサ29からの物品検知信号Dt(搬入検知信号)で特定される各列の物品搬入タイミングに基づいて、搬送モータ21による選別搬送コンベア2の搬送駆動の速度を制御することができる第2のコントローラの機能を併有している。   The sorting drive control unit 41 also loads the articles in each column specified by the article detection signal Dt (carrying detection signal) from the article detection sensor 29 for each column of the own machine even when disconnected from the sorting control unit 32. Based on the timing, it also has the function of a second controller that can control the speed of transport drive of the sorting transport conveyor 2 by the transport motor 21.

さらに、前述の通り、多列の選別搬送コンベア2で構成される並列搬送機構6は、多列の選別搬送コンベア2の列ごとの搬送速度を変化させることができる複数の可変速の搬送モータ21を有しているので、多列の選別搬送コンベア2に向けて計量コンベア1による検査済みの複数の物品Wが供給されるとき、選別駆動制御部41は、制御部13からの列数分の各列の選別搬送要求信号Mcおよび物品検知センサ29の検知信号を基に、各列の選別搬送コンベア2の搬送速度制御を対応する搬送モータ21の速度制御により実行する。   Further, as described above, the parallel transport mechanism 6 including the multi-row sorting and transporting conveyor 2 has a plurality of variable-speed transport motors 21 that can change the transport speed for each row of the multi-row sorting and transporting conveyor 2. Therefore, when a plurality of inspected articles W by the weighing conveyor 1 are supplied toward the multi-row sorting and conveying conveyor 2, the sorting drive control unit 41 is equal to the number of columns from the control unit 13. Based on the sorting / conveying request signal Mc of each row and the detection signal of the article detection sensor 29, the carrying speed control of the sorting / conveying conveyor 2 of each row is executed by the speed control of the corresponding carrying motor 21.

具体的には、選別駆動制御部41は、前述の第1のコントローラ機能により、制御部13からの選別搬送要求信号Mcのパルス幅や電圧からそれに応じた所定の搬送速度となるように搬送モータ21を制御する。あるいは、選別駆動制御部41は、第2のコントローラの機能により、列ごとの物品検知センサ29の検知信号から、あるいは単一の物品検知センサ29の検知信号と制御部13その他の上流側の装置から予め入力したタイミング(時間差)信号とから、列ごとの物品Wの投入タイミングを検知し、そのタイミングに応じて各列の選別搬送コンベア2の搬送速度を制御することも可能である。このような機能により、選別駆動制御部41は、各列の物品Wの検査後の経過時間から各列の物品Wが選別搬送区間Zに達すると予想される期間内に、物品検知センサ29によって物品Wの搬入が検出されるか否かを物品検知新号Dtの立上りで判定するとともに、その搬入の有無およびタイミングと制御部13から入力される選別信号RJとに応じて、多列の選別搬送コンベア2を有する並列搬送機構6を制御することができる。   Specifically, the sorting drive control unit 41 uses the first controller function described above to control the carry motor so that a predetermined carrying speed is obtained from the pulse width and voltage of the sorting conveyance request signal Mc from the control unit 13. 21 is controlled. Alternatively, the sorting drive control unit 41 can detect the detection signal of the article detection sensor 29 for each column or the detection signal of the single article detection sensor 29 and the control unit 13 or other upstream device by the function of the second controller. It is also possible to detect the input timing of the articles W for each column from the timing (time difference) signal input in advance from and to control the conveying speed of the sorting conveyor 2 in each column according to the timing. With such a function, the sorting drive control unit 41 uses the article detection sensor 29 within a period in which the articles W in each row are expected to reach the sorting conveyance section Z from the elapsed time after the inspection of the articles W in each row. Whether the loading of the article W is detected is determined at the rising edge of the new article detection number Dt, and multi-row sorting is performed according to the loading presence / absence and timing and the sorting signal RJ input from the control unit 13. The parallel transport mechanism 6 having the transport conveyor 2 can be controlled.

また、選別駆動制御部41は、計量コンベア1側から列数分の所定数の物品Wが供給されるとき、所定数の物品Wを選別搬送区間Zに搬入させ、それら複数の物品Wの搬入のタイミングに応じて各列の選別搬送コンベア2の搬送速度を制御することにより、複数の物品Wの並列搬送のタイミング(搬送方向同位置を通過するタイミング)を調整した上で、後段コンベア3に対して複数の物品Wを搬入時よりも揃ったタイミングで受け渡し可能に搬出させることができるようになっている。ここでいう搬入時よりも揃ったタイミングとは、特定列の物品Wの搬送方向位置のばらつきが選別搬送区間Z内で縮小され、特定列の物品Wが選別搬送区間Zを出るときのタイミングのばらつきがこれらの物品Wが選別搬送区間Z内に入るときのタイミングのばらつきよりも抑えられていることを意味する。   In addition, when a predetermined number of articles W corresponding to the number of rows are supplied from the weighing conveyor 1 side, the sorting drive control unit 41 carries a predetermined number of articles W into the sorting conveyance section Z and carries in the plurality of articles W. By controlling the transport speed of the sorting and transporting conveyors 2 in each row according to the timing, the timing of the parallel transport of the plurality of articles W (the timing of passing through the same position in the transport direction) is adjusted, and the subsequent conveyor 3 On the other hand, it is possible to carry out a plurality of articles W so that they can be delivered at the same timing as when they are carried in. Here, the timing that is more uniform than the time of carrying in is the timing when the variation in the transport direction position of the articles W in the specific row is reduced in the sorting transport section Z and the articles W in the specific row exit the sorting transport section Z. It means that the variation is suppressed more than the variation in timing when these articles W enter the sorting conveyance section Z.

具体的には、計量コンベア1側から列数分の所定数の物品Wが供給されるとき、これら所定数の物品Wは、上流側の充填機等により略同時期に投入され並列搬送される一群をなすものの、その投入タイミングのずれやその後の搬送中のスリップ等により搬送方向の位置がばらついたものとなり得る。   Specifically, when a predetermined number of articles W corresponding to the number of rows are supplied from the weighing conveyor 1 side, the predetermined number of articles W are loaded and transported in parallel at approximately the same time by an upstream filling machine or the like. Although it forms a group, the position in the transport direction may vary due to a shift in the input timing, a slip during subsequent transport, or the like.

典型的には、例えば図1および図5に示すように、充填機等による投入順の違いや同時充填射出後の投入径路長の違い等によって、4列の物品Wの投入タイミングは列順に規則的にずれる場合がある。   Typically, for example, as shown in FIG. 1 and FIG. 5, the input timing of the four rows of articles W is regulated in the order of rows due to the difference in the order of loading by a filling machine or the like, the difference in the length of the charging path after simultaneous filling and injection, and the like. There is a case where it shifts.

この場合、選別駆動制御部41は、計量コンベア1側からの各列の検査済みの物品Wについての検査の結果と、その検査結果に対応する物品Wが各列の選別搬送区間Z内に搬入されるタイミングとに応じて、投入された検査済みの物品Wのうち後段コンベア3に搬出すべき良品の物品Wを搬送する特定列の選別搬送コンベア2、図5中では4列の選別搬送コンベア2の搬送速度V(L1)、V(L2)、V(L3)、V(L4)を、対応する列数分の可変速の搬送モータ21によってそれぞれ可変制御するようになっている。   In this case, the sorting drive control unit 41 carries the inspection results of the inspected articles W in each row from the weighing conveyor 1 side and the articles W corresponding to the inspection results into the sorting conveyance section Z in each row. In accordance with the timing of the transfer, the selected transfer conveyor 2 in a specific row that conveys the non-defective product W to be carried out to the subsequent conveyor 3 among the inspected articles W that have been input, and in FIG. The two conveyance speeds V (L1), V (L2), V (L3), and V (L4) are variably controlled by the variable-speed conveyance motors 21 corresponding to the number of corresponding columns.

また、制御部13および選別駆動制御部41において、選別搬送コンベア2による選別搬送区間Zは、図1に示すように、計量コンベア1からの搬入速度に等しい速度で物品Wを選別搬送区間Z内に搬入する第1搬送区間Z1と、物品Wを並列搬送しつつその搬送中の所定数の物品Wの並列搬送のタイミングを揃える第2搬送区間Z2と、並列搬送のタイミング揃った所定数の物品Wを後段コンベア3の搬送速度に等しい速度で後段コンベア3に搬出する第3搬送区間Z3とに区画設定されている。   Further, in the control unit 13 and the sorting drive control unit 41, the sorting and conveying section Z by the sorting and conveying conveyor 2 moves the articles W in the sorting and conveying section Z at a speed equal to the carry-in speed from the weighing conveyor 1 as shown in FIG. The first transport section Z1 to be carried in, the second transport section Z2 for aligning the parallel transport timing of the predetermined number of articles W while transporting the articles W in parallel, and the predetermined number of articles with the parallel transport timing aligned. W is divided into a third transport zone Z3 that is transported to the rear conveyor 3 at a speed equal to the transport speed of the rear conveyor 3.

ここで、第1搬送区間Z1は、物品Wの重心が計量コンベア1上から選別搬送コンベア2上に移動するのに足りる搬送時間として、第3搬送区間Z3は、物品Wの重心が選別搬送コンベア2上から後段コンベア3に移動するのに足りる搬送時間として、それぞれ設定されている。   Here, the first transport zone Z1 is a transport time sufficient for the center of gravity of the article W to move from the weighing conveyor 1 to the sorting transport conveyor 2, and the third transport zone Z3 is that the center of gravity of the article W is the sorting transport conveyor. 2 is set as a conveyance time sufficient to move from the top to the rear conveyor 3.

そして、選別駆動制御部41は、計量コンベア1側から複数列の選別搬送コンベア2の列数に対応する所定数の物品Wが供給されるとき、所定数の物品Wの検査の結果に対応する選別信号RJを計量コンベア1から入力するとともに、所定数の物品Wが選別搬送区間Zに搬入されるそれぞれの搬入タイミングを対応する所定列の物品検知センサ29の検知信号Dtから検知し、例えば図5に示すような制御を実行するようになっている。   When the predetermined number of articles W corresponding to the number of rows of the sorting and conveying conveyors 2 in the plurality of rows is supplied from the weighing conveyor 1 side, the sorting drive control unit 41 corresponds to the result of the inspection of the predetermined number of items W. The sorting signal RJ is input from the weighing conveyor 1 and the loading timing at which a predetermined number of articles W are carried into the sorting conveyance section Z is detected from the detection signal Dt of the corresponding article detection sensor 29 in the corresponding row. The control as shown in FIG. 5 is executed.

すなわち、複数列の選別搬送コンベア2のうちいずれか1列の選別搬送区間Zに物品Wが搬入されてから搬出されるまでの搬送時間に対応する所定の選別搬送期間TAごとに、所定数の物品Wのうち選別搬送区間Zに最初に搬入された時刻t1の検知信号Dt(L1)に対応する先行物品Wを速度制御期間TP1中に略定速搬送しつつ、所定数の物品Wのうち先行物品Wより後に選別搬送区間Zに搬入された時刻t2、t3、t4の検知信号Dt(L2)、Dt(L3)、Dt(L4)に対応する3つの後続物品Wを、それぞれの搬入タイミングに応じた速度差ΔVa、ΔVb、ΔVcおよび速度制御期間TP2、TP3、TP4で加速搬送する。   That is, a predetermined number of sorting transport periods TA corresponding to a transport time from when an article W is carried into one sorting sorting section Z of the plurality of sorting transporting conveyors 2 until it is unloaded. Among the predetermined number of articles W, the preceding article W corresponding to the detection signal Dt (L1) at the time t1 first carried into the sorting conveyance section Z among the articles W is conveyed at a substantially constant speed during the speed control period TP1. The three subsequent articles W corresponding to the detection signals Dt (L2), Dt (L3), and Dt (L4) at the times t2, t3, and t4, which are carried into the sorting and conveying section Z after the preceding article W, are carried in, respectively. Accelerated transport is performed at speed differences ΔVa, ΔVb, ΔVc and speed control periods TP2, TP3, TP4 according to the above.

具体的には、まず、第1列の先頭の物品W(L1)が選別搬送区間Zに最初に搬入された時点を時刻t1とし、その時点から後続物品Wが選別搬送区間Zに搬入される時刻t2、t3、t4までの経過時間をそれぞれTa、Tb、Tcとする。また、第2列から第4列の後続物品W(L2)、W(L3)、W(L4)が選別搬送区間Z中で増速搬送される速度をそれぞれV2、V3、V4とし、それぞれの増速前の各列の搬送速度をV1とする。この場合、増速比率V2/V1は、概ねTP1/(TP1−Ta)、増速比率V3/V1は、概ねTP1/(TP1−Tb)、増速比率V4/V1は、概ねTP1/(TP1−Tc)に設定することができ、これらの増速比率に応じた速度差ΔVa、ΔVb、ΔVcを設定することができる。速度制御期間TP2、TP3、TP4は、それぞれ概ね(TP1−Ta)、(TP1−Tb)、(TP1−Tc)に対応するものとなる。   Specifically, first, the time when the first article W (L1) in the first row is first carried into the sorting conveyance section Z is set as time t1, and the subsequent article W is carried into the sorting conveyance section Z from that time. The elapsed times up to the times t2, t3, and t4 are Ta, Tb, and Tc, respectively. In addition, the speed at which the subsequent articles W (L2), W (L3), and W (L4) in the second to fourth rows are transported at an increased speed in the sorting transport zone Z are V2, V3, and V4, respectively. The conveyance speed of each row before the speed increase is V1. In this case, the speed increase ratio V2 / V1 is approximately TP1 / (TP1-Ta), the speed increase ratio V3 / V1 is approximately TP1 / (TP1-Tb), and the speed increase ratio V4 / V1 is approximately TP1 / (TP1). −Tc), and the speed differences ΔVa, ΔVb, ΔVc corresponding to these speed increasing ratios can be set. The speed control periods TP2, TP3, and TP4 generally correspond to (TP1-Ta), (TP1-Tb), and (TP1-Tc), respectively.

ここで、速度制御期間TP1は、選別搬送区間Z中の第2搬送区間Z2に対応する期間であり、選別搬送期間TAの開始時刻t0より後に始まり、選別搬送期間TAの終了時刻t6より前に終了する。   Here, the speed control period TP1 is a period corresponding to the second transport section Z2 in the sorting transport section Z, and starts after the start time t0 of the sorting transport period TA and before the end time t6 of the sorting transport period TA. finish.

また、速度差ΔVa、ΔVb、ΔVcは、先行物品Wの検知信号Dt(L1)の立上りから各検知信号Dt(L2)、Dt(L3)、Dt(L4)の立上りまでの経過時間に比例して大きくなり、速度制御期間TP2、TP3、TP4は、開始時刻t2、t3、t4が順次遅れているにもかかわらず速度制御期間TP1の終了時刻t5でそれぞれ共に終了するように、速度制御期間TP1より短い時間に設定されている。なお、ここでの速度制御期間TP2、TP3、TP4や速度差ΔVa、ΔVb、ΔVcの比は、速度制御期間TP1の終了時刻t5を早めるか否かによって、適宜選択できる。   Further, the speed differences ΔVa, ΔVb, ΔVc are proportional to the elapsed time from the rise of the detection signal Dt (L1) of the preceding article W to the rise of each detection signal Dt (L2), Dt (L3), Dt (L4). The speed control periods TP1, TP3, and TP4 are both ended at the end time t5 of the speed control period TP1 even though the start times t2, t3, and t4 are sequentially delayed. It is set to a shorter time. Here, the ratio of the speed control periods TP2, TP3, TP4 and the speed differences ΔVa, ΔVb, ΔVc can be appropriately selected depending on whether or not the end time t5 of the speed control period TP1 is advanced.

さらに、速度制御期間TP1中における略定速搬送とは、前段の計量コンベア1と後段コンベア3の搬送速度に差がない場合には、一定速度であるが、前段の計量コンベア1と後段コンベア3の搬送速度に差がある場合には、一定の時間変化率で搬送速度V(L1)を徐々に変化させる速度漸増または速度漸減の制御とし得ることを意味する。以下、同様の意味で、単に定速搬送の語を用いる。   Further, the substantially constant-speed conveyance during the speed control period TP1 is a constant speed when there is no difference in the conveyance speed between the first-stage weighing conveyor 1 and the second-stage conveyor 3, but the first-stage weighing conveyor 1 and the second-stage conveyor 3 If there is a difference in the transport speeds, it means that the speed gradually increasing or gradually decreasing can be controlled by gradually changing the transport speed V (L1) at a constant rate of time change. Hereinafter, the term “constant speed conveyance” is simply used in the same meaning.

次に、動作について説明する。   Next, the operation will be described.

上述のように構成された本実施形態の選別装置を備えた重量選別システムにおいては、上流からの、あるいは図示しない運転ボタンの操作による検査開始信号に基づいて、制御部13で計量コンベア1の搬送駆動信号が生成されるとともに、選別搬送コンベア2の選別駆動制御部41に対して搬送モータ21による搬送駆動を要求する選別搬送要求信号Mcが出力される。このとき、選別駆動制御部41は、選別搬送要求信号Mcのパルス幅や電圧に応じた所定の搬送速度Vとなるように搬送モータ21を制御する。   In the weight sorting system having the sorting device of the present embodiment configured as described above, the control unit 13 transports the weighing conveyor 1 based on an inspection start signal from upstream or by operating an operation button (not shown). A drive signal is generated, and a sorting / conveying request signal Mc requesting the sorting / driving control unit 41 of the sorting / conveying conveyor 2 to be driven by the carrying motor 21 is output. At this time, the sorting drive control unit 41 controls the carry motor 21 so that a predetermined carrying speed V corresponding to the pulse width and voltage of the sorted carrying request signal Mc is obtained.

そして、計量コンベア1に順次投入される物品Wが、所定の検査方式で重量計測されて各物品Wの重量が許容範囲内か否かが検査され、その検査結果に応じた選別信号RJが制御部13によって生成される。   Then, the articles W sequentially put into the weighing conveyor 1 are weighed by a predetermined inspection method to inspect whether or not the weight of each article W is within an allowable range, and the sorting signal RJ corresponding to the inspection result is controlled. Generated by the unit 13.

このとき、計量コンベア1の制御部13では、各物品Wについての重量の合否判定結果を表す検査結果信号が、例えばOKまたはNG信号のような信号形態で生成されるとともに、その検査結果信号に対応する物品Wが選別搬送区間Zに到達するときに振分け機構28をその検査結果信号に対応する振分け方向に向けるように、選択的にかつ適時に選別信号RJが生成され、選別駆動制御部41に出力される。   At this time, in the control unit 13 of the weighing conveyor 1, an inspection result signal indicating the result of the weight acceptance / rejection determination for each article W is generated in a signal form such as an OK or NG signal, and the inspection result signal is included in the inspection result signal. A sorting signal RJ is generated selectively and in a timely manner so that the sorting mechanism 28 is directed in the sorting direction corresponding to the inspection result signal when the corresponding article W reaches the sorting conveyance section Z, and the sorting drive control unit 41. Is output.

いま、例えば多列の選別搬送コンベア2に搬入される複数の物品Wについての検査結果信号がそれぞれOK信号であり、それぞれのOK信号の発生から想定される到達期間内に対応する搬送レーンの物品検知センサ29で良品の物品Wが順次検知され、振分け機構28は良品搬出が可能な待機姿勢である第1姿勢に保持されているものとする。   Now, for example, the inspection result signals for a plurality of articles W carried into the multi-row sorting and conveying conveyor 2 are each OK signals, and the articles in the corresponding transport lane within the arrival period assumed from the generation of the respective OK signals. Assume that the non-defective article W is sequentially detected by the detection sensor 29, and the distribution mechanism 28 is held in the first posture which is a standby posture in which the non-defective product can be taken out.

また、図1に示すように、同図中に実線で示す4列分の物品Wのうち最も先頭側(図1中の右側)に位置する先行物品W(L1)が選別搬送区間Zに搬入された後、次の後続物品W(L2)が選別搬送区間Zに搬入され、さらに後続する後続物品W(L3)、W(L4)が順に選別搬送区間Zに搬入されるものとする。   Further, as shown in FIG. 1, the preceding article W (L1) located at the foremost side (the right side in FIG. 1) among the four rows of articles W indicated by solid lines in FIG. After that, it is assumed that the next succeeding article W (L2) is carried into the sorting and conveying section Z, and the subsequent succeeding articles W (L3) and W (L4) are carried into the sorting and conveying section Z in order.

この場合、制御部13からの選別搬送要求信号Mcおよび選別信号RJを受けた選別駆動制御部41により、複数列の選別搬送コンベア2の搬送速度が列ごとに調整されて、複数の物品W(L1)〜W(L4)が同図中に複数種の仮想線(二点鎖線、破線、点線、一点鎖線)で示すように相互の搬送方向位置を接近させ、所定列数分、例えば4つの物品Wの重心が第2搬送区間Z2を通過するまでには、それらの並列搬送のタイミングが同図中に一点鎖線で示すように揃えられる。   In this case, the sorting drive control unit 41 that has received the sorting and transport request signal Mc and the sorting signal RJ from the control unit 13 adjusts the transport speed of the plurality of rows of sorting and transporting conveyors 2 for each row, so that a plurality of articles W ( L1) to W (L4) are moved closer to each other in the transport direction as indicated by a plurality of types of virtual lines (two-dot chain line, broken line, dotted line, one-dot chain line) in the figure, By the time the center of gravity of the article W passes through the second transport section Z2, the parallel transport timings are aligned as shown by the alternate long and short dash line in FIG.

このとき、図5に示すように、選別搬送区間Zに搬入された先行物品W(L1)が速度制御期間TP1中に略定速搬送されるとともに、3つの後続物品Wが、それぞれの搬入タイミングに応じた速度差ΔVa〜ΔVcおよび速度制御期間TP2〜TP4で加速搬送され、4つの物品Wの重心が第2搬送区間Z2を通過する時刻t5に達するまでに、それら4つの物品Wの並列搬送のタイミングが図1中に一点鎖線の仮想線で示すように揃えられる。   At this time, as shown in FIG. 5, the preceding article W (L1) carried into the sorting and conveying section Z is conveyed at a substantially constant speed during the speed control period TP1, and the three subsequent articles W are loaded at respective loading timings. Accelerating and transporting at a speed difference ΔVa to ΔVc and a speed control period TP2 to TP4 according to the time until the center of gravity of the four articles W passes through the second transport section Z2 until the time t5 is reached. Are aligned as shown by the phantom lines in FIG.

一方、いま、例えば多列の選別搬送コンベア2に搬入される複数の物品Wについての検査結果信号が一部の物品WについてNG信号であり、他の物品WについてそれぞれOK信号であったとする。   On the other hand, for example, it is assumed that the inspection result signals for a plurality of articles W carried into the multi-row sorting and conveying conveyor 2 are NG signals for some articles W and OK signals for other articles W, respectively.

この場合、それぞれの検査結果信号の発生から想定される到達期間内に、対応する搬送レーンの物品検知センサ29で良品または不良品の物品Wが順次検知されるとともに、それらの検査結果に対応する選別信号RJが選別駆動制御部41に入力される。   In this case, the non-defective or defective articles W are sequentially detected by the article detection sensors 29 in the corresponding transport lanes within the arrival period assumed from the generation of the respective inspection result signals, and corresponding to the inspection results. The sorting signal RJ is input to the sorting drive control unit 41.

そして、例えば図6に示す第1列目(同図中の最上方の列)の選別搬送コンベア2については、振分け機構28は不良品の排出落下が可能な第2姿勢となり、OK信号に対応する選別信号RJが入力される第2〜4列目については、振分け機構28は良品搬出が可能な第1姿勢に保持される。   For example, for the sorting and conveying conveyor 2 in the first row (the uppermost row in FIG. 6) shown in FIG. 6, the sorting mechanism 28 is in the second posture in which defective products can be discharged and dropped, and corresponds to the OK signal. In the second to fourth columns to which the sorting signal RJ to be input is input, the sorting mechanism 28 is held in the first posture in which the non-defective product can be taken out.

この場合、制御部13からの選別搬送要求信号Mcおよび選別信号RJを受けた選別駆動制御部41により、複数列の選別搬送コンベア2の搬送速度が列ごとに調整されて、第2姿勢となった第1列目の選別搬送コンベア2については、例えば計量コンベア1と同一速度の定速搬送状態となる。そして、良品搬送可能な第1姿勢に保持される第2列ないし第4列の選別搬送コンベア2については、複数の物品W(L2)〜W(L4)が同図中に複数種の仮想線(二点鎖線、破線、点線、一点鎖線)で示すように、相互の搬送方向位置を接近させ、所定列数分の物品Wの重心が第2搬送区間Z2を通過するまでに、それらの並列搬送のタイミングが同図中に一点鎖線で示すように揃えられる。   In this case, the sorting drive control unit 41 that has received the sorting and transport request signal Mc and the sorting signal RJ from the control unit 13 adjusts the transport speed of the plurality of rows of sorting and transporting conveyors 2 for each row, and takes the second posture. In addition, the sorting and conveying conveyor 2 in the first row is in a constant speed conveying state at the same speed as the weighing conveyor 1, for example. And about the 2nd row | line | column 4th selection conveyance conveyor 2 hold | maintained in the 1st attitude | position which can carry a good article, several articles | goods W (L2) -W (L4) are several types of virtual lines in the figure. As indicated by (two-dot chain line, broken line, dotted line, and alternate long and short dash line), the positions in the conveyance direction are brought close to each other, and the center of gravity of articles W for a predetermined number of rows passes through the second conveyance section Z2 in parallel. The conveyance timing is aligned as shown by the alternate long and short dash line in FIG.

この場合の搬送制御は、選別搬送区間Zに搬入された第2列目の先行物品W(L2)が速度制御期間TP2中に定速搬送されるとともに、2つの後続物品Wが、それぞれの搬入タイミングに応じた速度差ΔVb、ΔVcおよび速度制御期間TP3、TP4で加速搬送され、3つの物品Wの重心が第2搬送区間Z2を通過する時刻t5に達するまでに、それらの並列搬送のタイミングが同図中に一点鎖線で示すように揃えられることになる。   In this case, the conveyance control is performed such that the second row of preceding articles W (L2) carried into the sorting conveyance section Z is conveyed at a constant speed during the speed control period TP2, and the two subsequent articles W are carried in respectively. Accelerated transport is performed in the speed differences ΔVb and ΔVc corresponding to the timing and the speed control periods TP3 and TP4, and until the center of gravity of the three articles W passes through the second transport section Z2, the parallel transport timing is reached. They are aligned as shown by the alternate long and short dash line in FIG.

また、第2列目以降のいずれかにNGが生じたときは、その列の選別搬送コンベア2が第2姿勢となって定速搬送状態となり、残りの3列について物品Wの並列搬送のタイミングが揃えられることになる。すなわち、並列搬送のタイミングを揃えるための搬送速度制御は、良品の物品Wについてのみ実行すればよい。   Further, when NG occurs in any of the second and subsequent rows, the sorting and conveying conveyor 2 in that row is in the second posture and is in a constant speed conveying state, and the timing of the parallel conveyance of the articles W for the remaining three rows Will be aligned. That is, the conveyance speed control for aligning the parallel conveyance timing may be executed only for the non-defective article W.

もっとも、本実施形態では、時刻t5を早目に設定することで、第2姿勢にて物品Wを排出落下させるときの速度を通常と同程度にできる場合、NG信号の発生の有無およびその発生レーンの位置にかかわらず、搬送制御自体は第5図に示した場合と同様に実行することも可能である。   However, in the present embodiment, when the time when the article W is discharged and dropped in the second posture can be set to the same level as usual by setting the time t5 early, whether or not an NG signal is generated and its generation. Regardless of the position of the lane, the transport control itself can be executed in the same manner as in the case shown in FIG.

このように、本実施形態の選別装置およびそれを備えた重量選別システムにおいては、複数列の選別搬送コンベア2への前段からの搬入タイミングにずれがあっても、少なくとも後段コンベア3側に搬出すべき特定列の選別搬送コンベア2についてそのタイミングのずれを抑えるように物品Wの搬送速度を調整することができる。したがって、確実な選別動作と後段側への適時の搬出が可能な選別装置およびそれを備えた重量選別システムとなる。   As described above, in the sorting apparatus according to the present embodiment and the weight sorting system including the sorting apparatus, even if there is a shift in the timing of carrying in from the preceding stage to the plural rows of sorting and conveying conveyors 2, the sorting apparatus is carried out at least to the rear conveyor 3 side. The conveyance speed of the articles W can be adjusted so as to suppress the timing shift of the sorting and conveying conveyor 2 in the specific row. Therefore, a sorting apparatus capable of reliable sorting operation and timely delivery to the rear stage and a weight sorting system including the sorting apparatus are provided.

また、本実施形態では、選別駆動制御部41が、所定数の物品Wのうち選別搬送区間Zに最初に搬入された先行物品Wを定速搬送しつつ、所定数の物品Wのうち先行物品Wより後に選別搬送区間Zに搬入された後続物品Wを加速搬送する。したがって、複数列の選別搬送コンベア2で並列搬送される所定数の物品Wのいずれかにスリップ等による搬送遅れが生じたとしても、所定数の物品Wのうち先頭の物品Wを基準に他の物品Wを加速搬送して、所定数の物品Wの後段コンベア側への搬出タイミングを揃えることができる。   Further, in the present embodiment, the sorting drive control unit 41 transports the preceding article W first carried into the sorting conveyance section Z out of the predetermined number of articles W at a constant speed, while the preceding article out of the predetermined number of articles W. Subsequent articles W carried into the sorting and conveying section Z after W are accelerated and conveyed. Therefore, even if a conveyance delay due to slip or the like occurs in any of the predetermined number of articles W that are conveyed in parallel by the plurality of rows of sorting and conveying conveyors 2, the other items based on the leading article W among the predetermined number of articles W The articles W can be accelerated and conveyed, and the delivery timing of the predetermined number of articles W to the rear conveyor side can be aligned.

さらに、本実施形態では、選別搬送コンベア2の選別搬送区間Zが、前段の計量コンベア1からの搬入速度に等しい速度で物品Wを選別搬送区間Z内に搬入する第1搬送区間Z1と、後段コンベア3の搬送速度に等しい速度で物品Wを後段コンベア3に搬出する第3搬送区間Z3とを有しているので、計量コンベア1からの搬入や後段コンベア3への搬出の動作が円滑化されるとともに、第2搬送区間Z2内での搬送速度制御が物品Wの搬送方向長さの大小による影響を受け難いものにできる。よって、前述のように、NG信号の発生の有無およびその発生レーンの位置にかかわらず、搬送制御自体は第5図に示した場合と同様に実行することも可能になり、物品Wの搬送方向長さが比較的大きい場合にも的確な搬送タイミング調整および選別動作を実行させることができる。   Furthermore, in the present embodiment, the sorting and conveying section Z of the sorting and conveying conveyor 2 includes a first conveying section Z1 that carries the article W into the sorting and conveying section Z at a speed equal to the carry-in speed from the preceding weighing conveyor 1; Since it has the 3rd conveyance section Z3 which carries the articles | goods W to the back | latter stage conveyor 3 at the speed equal to the conveyance speed of the conveyor 3, the operation | movement of carrying in from the measurement conveyor 1 and carrying out to the back | latter stage conveyor 3 is smoothed. In addition, the conveyance speed control in the second conveyance section Z2 can be made less susceptible to the influence of the length of the article W in the conveyance direction. Therefore, as described above, regardless of whether or not an NG signal is generated and the position of the lane in which the NG signal is generated, the conveyance control itself can be executed in the same manner as in the case shown in FIG. Even when the length is relatively large, it is possible to execute an accurate conveyance timing adjustment and selection operation.

このように、本実施形態によれば、複数の選別搬送コンベア2への前段からの搬入タイミングにずれがあったとしても、確実な選別動作と後段側への適時の搬出が可能な選別装置を提供することができ、それを用いたコンパクトな選別性能に優れた重量選別システムを提供することができる。   Thus, according to this embodiment, even if there is a shift in the timing of carrying in from the preceding stage to the plurality of sorting and conveying conveyors 2, the sorting apparatus capable of reliable sorting operation and timely delivery to the subsequent stage side. It is possible to provide a weight sorting system that is excellent in compact sorting performance using the same.

なお、上述の一実施形態では、所定数の物品Wのうち選別搬送区間Zに最初に搬入された先行物品Wを速度制御期間TP1中に略定速搬送しつつ、3つの後続物品Wを、それぞれの搬入タイミングに応じた速度差ΔVa〜ΔVcおよび速度制御期間TP2〜TP4で加速搬送する先行物品基準の搬送速度制御としていたが、後続物品Wのいずれか、例えば最後に選別搬送区間Zに到達する後続物品基準の搬送速度制御とすることもできる。また、選別信号RJの入力を待つ運転中の待機時に不良品排出可能な第2姿勢で待機するようにする場合は、少なくとも自重で、さらにばね等の付勢手段を設けることにより不良品の排出落下が可能な待機姿勢をとることができ、その場合には、選別搬送コンベア2を良品通過側に移行した後に、または選別搬送コンベア2を良品通過側に移行させながら、選別搬送速度を可変制御することもできる。   In the above-described embodiment, among the predetermined number of articles W, the preceding article W that is first carried into the sorting and conveying section Z is conveyed at a substantially constant speed during the speed control period TP1, and the three subsequent articles W are Although the conveyance speed control based on the preceding article that is accelerated and conveyed in the speed differences ΔVa to ΔVc and the speed control periods TP2 to TP4 according to the respective carry-in timings, one of the subsequent articles W, for example, finally reaches the sorting conveyance section Z It is also possible to control the conveyance speed based on the subsequent article. In addition, when waiting in the second posture during which the defective product can be discharged while waiting for the input of the sorting signal RJ, the defective product is discharged by providing an urging means such as a spring at least by its own weight. It is possible to take a stand-by posture that can be dropped. In this case, after the sorting and conveying conveyor 2 is moved to the non-defective product passing side, or while the sorting and conveying conveyor 2 is moved to the non-defective product passing side, the sorting and conveying speed is variably controlled. You can also

図7および図8は、後続物品基準の搬送速度制御を行うようにした他の実施形態に係る選別装置を示すものである。
(Other embodiments)
FIG. 7 and FIG. 8 show a sorting apparatus according to another embodiment in which the conveyance speed control based on the subsequent article is performed.

なお、本実施形態は、上述の一実施形態と類似する選別装置および重量選別システムの構成を有しているので、同一構成については図1ないし図6に示した対応する構成要素の符号を用いつつ、以下、相違点についてのみ、図7および図8を用いて説明する。   In addition, since this embodiment has a configuration of a sorting apparatus and a weight sorting system similar to the above-described one embodiment, the same components are denoted by the reference numerals of corresponding components shown in FIGS. 1 to 6. However, only differences will be described below with reference to FIGS.

両図に示すように、本実施形態においては、選別駆動制御部41は、計量コンベア1側から複数列の選別搬送コンベア2の列数に対応する所定数の物品Wが供給されるとき、所定数の物品Wの検査の結果に対応する選別信号RJを計量コンベア1から入力するとともに、所定数の物品Wが選別搬送区間Zに搬入されるそれぞれの搬入タイミングを対応する所定列の物品検知センサ29の検知信号Dtから検知し、例えば図8に示すような制御を実行するようになっている。   As shown in both figures, in the present embodiment, the sorting drive control unit 41 is configured when a predetermined number of articles W corresponding to the number of rows of the sorting and conveying conveyors 2 in a plurality of rows is supplied from the weighing conveyor 1 side. A selection signal RJ corresponding to the inspection results of a number of articles W is inputted from the weighing conveyor 1 and a predetermined number of article detection sensors corresponding to the respective carry-in timings when a predetermined number of articles W are carried into the sorting conveyance section Z For example, the control shown in FIG. 8 is executed based on the detection signal Dt.

すなわち、複数列の選別搬送コンベア2のうちいずれか1列の選別搬送区間Zに物品Wが搬入されてから搬出されるまでの搬送時間に対応する所定の選別搬送期間TAごとに、所定数の物品Wのうち選別搬送区間Zに最後に搬入された検知信号Dt(L4)に対応する後続物品W(L4)を速度制御期間TP4中に略定速搬送できるように、所定数の物品Wのうち後続物品W(L4)より先行して選別搬送区間Zに搬入された検知信号Dt(L1)、Dt(L2)、Dt(L3)に対応する3つの後続物品Wを、それぞれの搬入タイミングに応じた速度差ΔVe、ΔVf、ΔVgおよび速度制御期間TP1、TP2、TP3の条件で減速搬送する。   That is, a predetermined number of sorting transport periods TA corresponding to a transport time from when an article W is carried into one sorting sorting section Z of the plurality of sorting transporting conveyors 2 until it is unloaded. Among the articles W, a predetermined number of articles W can be conveyed so that the succeeding article W (L4) corresponding to the detection signal Dt (L4) last carried into the sorting conveyance section Z can be conveyed at a substantially constant speed during the speed control period TP4. Of these, the three subsequent articles W corresponding to the detection signals Dt (L1), Dt (L2), and Dt (L3) carried into the sorting and conveying section Z prior to the subsequent article W (L4) are set to the respective carry-in timings. Decelerated transport is performed under the conditions of the corresponding speed differences ΔVe, ΔVf, ΔVg and speed control periods TP1, TP2, TP3.

ここで、速度差ΔVe、ΔVf、ΔVgが、最後の後続物品Wの検知信号Dt(L4)の立上りを基準として各検知信号Dt(L1)、Dt(L2)、Dt(L3)の立上りが先行する時間に比例して大きくなるように設定されている。   Here, the speed differences ΔVe, ΔVf, ΔVg are preceded by the rise of each detection signal Dt (L1), Dt (L2), Dt (L3) with reference to the rise of the detection signal Dt (L4) of the last succeeding article W. It is set so as to increase in proportion to the time to perform.

具体的には、例えば図7、図8に示すように、先頭の物品W(L1)が選別搬送区間Zに最初に搬入された時刻t1から最後の後続物品W(L4)が選別搬送区間Zに搬入される時刻t4までの経過時間をTe、第2番目の物品W(L2)が選別搬送区間Zに搬入された時刻t2から最後の後続物品W(L4)が選別搬送区間Zに搬入されるまでの経過時間をTf、第3番目の物品W(L3)が選別搬送区間Zに搬入された時刻t3から最後の後続物品W(L4)が選別搬送区間Zに搬入されるまでの経過時間をTgとし、第1列から第3列の物品W(L1)、W(L2)、W(L3)が選別搬送区間Z中で減速搬送される速度V(L1)、V(L2)、V(L3)をそれぞれV11、V12、V13とし、その減速前の各列の搬送速度をV1とすると、減速比率V11/V1は、概ね(TP1−Te)/TP1、減速比率V12/V1は、概ね(TP1−Tf)/TP1、減速比率V13/V1は、概ね(TP1−Tg)/TP1に設定でき、これらの減速比率に応じた速度差ΔVe、ΔVf、ΔVgが設定できる。この場合、速度制御期間TP1〜TP4は、それぞれ概ね(TP1−Te)に対応するものとなる。なお、ここでの速度制御期間TP1、TP2、TP3や速度差ΔVe、ΔVf、ΔVgの比も、一実施形態の場合と同様に、速度制御期間TP1の終了時刻t5を早めるか否かによって、適宜選択できる。   Specifically, for example, as shown in FIGS. 7 and 8, the last succeeding article W (L4) from the time t1 when the first article W (L1) is first carried into the sorting and conveying section Z is selected and conveyed to the sorting and conveying section Z. The elapsed time up to time t4 being carried in to Te is Te, and from time t2 when the second article W (L2) is carried into the sorting conveyance section Z, the last subsequent article W (L4) is carried into the sorting conveyance section Z. Elapsed time until the last article W (L4) is carried into the sorting conveyance section Z from time t3 when the third article W (L3) was carried into the sorting conveyance section Z. Is the speed V (L1), V (L2), V at which the articles W (L1), W (L2), W (L3) in the first row to the third row are decelerated and conveyed in the sorting conveyance section Z. (L3) is set to V11, V12, and V13, respectively, and the conveyance speed of each row before the deceleration is V Then, the deceleration ratio V11 / V1 is approximately (TP1-Te) / TP1, the deceleration ratio V12 / V1 is approximately (TP1-Tf) / TP1, and the deceleration ratio V13 / V1 is approximately (TP1-Tg) / TP1. The speed differences ΔVe, ΔVf, ΔVg can be set in accordance with these reduction ratios. In this case, the speed control periods TP1 to TP4 substantially correspond to (TP1-Te), respectively. Note that the ratios of the speed control periods TP1, TP2, and TP3 and the speed differences ΔVe, ΔVf, and ΔVg here are also appropriately determined depending on whether or not the end time t5 of the speed control period TP1 is advanced as in the case of the embodiment. You can choose.

本実施形態においても、複数列の選別搬送コンベア2のうちいずれか1列の選別搬送区間Zに物品Wが搬入されてから搬出されるまでの搬送時間に対応する所定の選別搬送期間TAごとに、複数列の選別搬送コンベア2の列数に対応する所定数の物品Wの検査の結果に対応する選別信号RJを計量コンベア1の制御部13から入力するとともに、所定数の物品Wが選別搬送区間Zに搬入されるそれぞれの搬入タイミングを検知し、所定数の物品Wのうち選別搬送区間Zに最初に搬入された先行物品Wを減速搬送しつつ、所定数の物品Wのうち先行物品Wより後に選別搬送区間Zに搬入された後続物品Wを略定速搬送する。   Also in the present embodiment, every predetermined sorting and conveying period TA corresponding to the conveying time from when the article W is carried into the sorting and conveying section Z of one row of the plural rows of sorting and conveying conveyors 2 until it is carried out. The sorting signal RJ corresponding to the result of the inspection of a predetermined number of articles W corresponding to the number of rows of the sorting and conveying conveyors 2 in a plurality of rows is input from the control unit 13 of the weighing conveyor 1 and the predetermined number of articles W are sorted and conveyed. While detecting the respective carry-in timings to be carried into the section Z and decelerating and transporting the preceding articles W first carried into the sorting and conveying section Z among the predetermined number of articles W, the preceding articles W among the predetermined number of articles W The subsequent article W carried into the sorting and conveying section Z is conveyed at a substantially constant speed.

したがって、各列の選別搬送コンベア2への物品の搬入間隔に或る程度の余裕がある場合に、複数列の選別搬送コンベア2で並列搬送される所定数の物品Wのいずれかにスリップ等による搬送遅れが生じたとしても、所定数の物品Wのうち後続物品Wを基準に他の先行する物品Wを減速搬送して、所定数の物品Wの後段コンベア3側への搬出タイミングを上流側の搬入間隔に対応させたものにすることができ、さらに、選別搬送区間Zの上流側寄りの部分で搬送タイミング(同じ搬送方向位置を通過するタイミング)を揃えることができるので、選別排出動作等が要求される列の選別搬送コンベア2に対し速度制御を行ったとしても、その選別動作への影響を抑えることができる。   Therefore, when there is a certain margin in the interval of carrying articles to the sorting and conveying conveyors 2 in each row, any of a predetermined number of articles W conveyed in parallel by the sorting and conveying conveyors 2 in a plurality of rows is caused by slip or the like Even if a conveyance delay occurs, other preceding articles W among the predetermined number of articles W are decelerated and conveyed with reference to the succeeding articles W, and the delivery timing to the rear conveyor 3 side of the predetermined number of articles W is set upstream. In addition, the transport timing (the timing of passing through the same transport direction position) can be aligned at the upstream side of the sorting transport zone Z, so that the sorting and discharging operation, etc. Even if the speed control is performed for the sorting and conveying conveyor 2 in the row where the above is required, the influence on the sorting operation can be suppressed.

なお、上述の各実施形態においては、略同時に検査され並列搬送される同一グループの複数の物品Wのうち選別搬送区間Zに最初に搬入される先行物品を基準として後続物品の搬送速度を加速制御するか、あるいは、同一グループの複数の物品Wのうち選別搬送区間Zに最後に搬入される後続物品を基準として先行する他の物品の搬送速度を減速制御するものとしたが、選別搬送区間Zに複数の後続物品のうち選別搬送区間Zに最後に搬入される後続物品以外のものを基準として、それより先行する物品についての減速制御と、それより後の後続物品の加速制御とを組み合わせることも考えられる。また、選別搬送区間Zの上流側で後続物品を基準として先行する他の物品の減速制御を行い、全列の物品搬送タイミングを揃えた後に、全列の加速制御を行って、搬送遅れをなくすことも考えられる。   In each of the above-described embodiments, the conveyance speed of the subsequent article is accelerated and controlled based on the preceding article that is first carried into the sorting conveyance section Z among the plurality of articles W of the same group that are inspected and conveyed in parallel at substantially the same time. Or, it is assumed that the transport speed of another preceding article is decelerated and controlled based on the subsequent article that is finally carried into the sorting transport section Z among the plurality of articles W of the same group. Combining the deceleration control for the preceding article and the acceleration control for the succeeding article after that, with reference to the article other than the succeeding article that is finally brought into the sorting conveyance section Z among the plurality of succeeding articles. Is also possible. In addition, on the upstream side of the sorting and conveying section Z, the other articles preceding the succeeding article are decelerated, and after aligning the article conveying timing for all the rows, the acceleration control for all the rows is performed to eliminate the conveyance delay. It is also possible.

また、上述の各実施形態においては、選別搬送コンベア2をダウンドロップ型としていたが、ダウンドロップ型の下流側にアップアウト型を設けたものであってもよいし、重量不足の不良品を排出するダウンドロップ型の下流側に重量過多の不良品を排出するもう一つのダウンドロップ型の選別搬送コンベアを配置したものであってもよい。   In each of the above-described embodiments, the sorting / conveying conveyor 2 is a down-drop type. However, an up-out type may be provided on the downstream side of the down-drop type, and defective products with insufficient weight are discharged. Another down-drop type sorting and conveying conveyor that discharges an excessively heavy defective product may be disposed on the downstream side of the down-drop type.

さらに、上述の各実施形態では、上位の検査装置を計量コンベア1としていたが、重量計測式のものに限定されないことはいうまでもなく、例えば特許文献1に記載のように、複数の検査レーンごとに検査ができるようにした金属検出式の異物検出装置、前掲の特許文献2に記載のように、X線透過画像を搬送レーン相当の帯状領域に分割して複数の物品の同時検査を可能にしたX線異物検査装置、あるいは、特許文献3に記載のように、判定時の分割領域サイズを最適化するようにして不良品を確実に排除しつつ無駄な選別排出を低減させるようにした重量計測装置のような、他方式の検査装置を上位の検査装置として、これに選別装置を付設したり、上位の検査装置や物品投入手段と選別装置の間に他のコンベア等の搬送手段が介在し得ることも勿論である。多列の選別搬送コンベア2の列数(連数)が任意であることはいうまでもない。   Further, in each of the above-described embodiments, the upper inspection device is the weighing conveyor 1. However, it is needless to say that the weighing conveyor 1 is not limited, and for example, as described in Patent Document 1, a plurality of inspection lanes are used. Metal detection type foreign matter detection device that can be inspected every time, as described in the above-mentioned Patent Document 2, X-ray transmission images can be divided into strip-like areas corresponding to transport lanes, and multiple items can be inspected simultaneously X-ray foreign matter inspection apparatus, or as described in Patent Document 3, the size of the divided area at the time of determination is optimized so as to reliably eliminate defective products and reduce wasteful sorting and discharging An inspection device of another type, such as a weight measuring device, is used as a higher-level inspection device, and a sorting device is attached to this, or a conveying device such as another conveyor is provided between the higher-level inspection device or the article input means and the sorting device. Can intervene It is also a matter of course. Needless to say, the number of rows (sequential number) of the multi-row sorting and conveying conveyor 2 is arbitrary.
