Description

【0001】
【発明の属する技術分野】
この発明は、コンベア設備におけるコンベアライン系統切替制御方法に関するものである。
【0002】
【従来の技術】
図3に示すように、新旧2系統のコンベアライン上の被搬送部材をコンベアラインを切り替えて共通コンベアラインに搬送させるようにしたコンベア設備におけるコンベアライン系統切替制御方法において、コンベアラインをY形に構成し、図示左側に示す旧系統のコンベアライン11、12、13の運転中に、図示右側に示す新系統のコンベアライン14、15、13(コンベアライン13は新旧共通コンベアライン)に、系統を切替制御して運転させる方法が採用されている。この場合、旧系統のコンベアラインから新系統のコンベアラインへの切替は、コンピュータ等からの切替指令にて次のように制御される。
【0003】
まず、切替指令にてコンベアライン11を払出停止(タイマで荷払い時間をカウントし、カウントアップ後、停止させる)する。その後、コンベアライン12を払出停止した後、コンベアライン15を起動させ、コンベアライン15が始動し、タイマがタイムアップしたならコンベアライン14を起動(順序始動)させる。この起動でコンベアライン14が始動し、タイマがタイムアップしたなら(順序始動後)、新系統のコンベアラインの起動が完了する。
【0004】
【発明が解決しようとする課題】
上記のように構成されたコンベア設備の運転中におけるコンベアライン系統切替制御方法においては、基本的に旧系統(コンベアライン11−コンベアライン12−コンベアライン13)の荷払いが完了してから新系統(コンベアライン14−コンベアライン15−コンベアライン13)を起動させるため、旧系統の払出し完了から新系統の起動完了までに時間のロスが多くあり、効率がよくない。特に、コンベアライン11とコンベアライン14の上流に多くのコンベアラインがある場合は、さらに新系統の起動完了までに長時間を費やしてしまう恐れがあり、操業効率を低下させる問題もあった。
【0005】
この発明は上記の事情に鑑みてなされたもので、新旧系統コンベアラインの運転中の切替時における時間のロスを無くして操業効率を向上させたコンベア設備におけるコンベアライン系統切替制御方法を提供することを課題とする。
【0006】
【課題を解決するための手段】
この発明は、上記の課題を達成するために、新旧2系統のコンベアライン上の被搬送部材をコンベアラインを切り替えて共通コンベアラインに搬送させるようにしたコンベア設備におけるコンベアライン系統切替制御方法において、
新旧系統のコンベアラインに切替指令が与えれる第1工程と、切替指令が与えられると、旧系統のコンベアラインの荷払いが完了する時間を読み出す第2工程および新系統のコンベアライン上の被搬送部材が共通コンベアラインに到達する時間を読み出す第3工程と、前記第2工程で読み出された時間と第3工程で読み出された時間の差を計算する第4工程と、この第4工程で計算された時間を基に新系統の起動タイミング時間を予測する第5工程と、この第5工程で新系統のコンベアラインが起動されたなら旧系統のコンベアラインを荷払い後に停止させる第6工程とを備え、
前記第6工程は、旧系統のコンベアライン上の被搬送部材が、そのコンベアラインを通過したかを判断し、通過したなら荷払い時間が、正常範囲内かを見て、正常範囲内なら旧系統のコンベアラインを停止し、正常範囲内でないなら、予測より旧系統のコンベアラインの荷払いに時間がかかったとして、切替異常信号を発生して、系統の切替を停止する処理を有するものである。
【0007】
【発明の実施の形態】
以下この発明の実施の形態を図面に基づいて説明する。図1はこの発明の実施の形態を示す切替制御方法の工程説明図で、図1において、21は、新旧系統のコンベアラインに図示しないコンピュータ等の制御装置から切替指令が与えられる第1工程である。この第1工程21からコンベアラインに切替指令が与えられると、旧系統におけるコンベアライン11とコンベアライン12の荷払いが完了する時間を第2工程22で読み出す。また、前記切替指令が与えられると、新系統におけるコンベアライン上の被搬送部材が共通コンベアライン13に到達する時間を第3工程23で読み出す。
【0008】
前記第2工程22で読み出された時間と、第3工程23で読み出された時間との差を第4工程24で計算して、新系統の起動タイミング時間を第5工程25で予測する。この予測により、コンベアライン14上の被搬送部材がコンベアライン15に到達するタイミングでコンベアライン15が起動される。コンベアライン15が起動されたなら、旧系統のコンベアライン11、12はそれぞれ荷払い後、順次第6工程26で停止させて行く。
【0009】
次に上記切替制御方法の動作を図2に示すフローチャートにより述べる。まず、第1工程21から系統切替指令を新旧系統のコンベアラインに出す(S1)。切替指令があるかをステップS2で判断し、「Y」なら第2工程22における荷払い完了時間を読み出す(S3)。その後、第3工程23において新系統のコンベアライン14、15上の被搬送部材が共通コンベアライン13に到達する時間をステップS4で読み出す。
【0010】
第4工程24では、ステップS3で読み出された時間と、ステップS4で読み出された時間との差をステップS5で取り、新系統コンベアラインの起動タイミングをステップS6で予測する(第5工程25)。この予測に基づいてコンベアライン14、15を起動させる。その後、ステップS7で、コンベアライン11上の被搬送部材は、コンベアライン11を通過したかを判断し、「Y」ならステップS8で荷払い時間は、正常範囲内かを見て、「Y」ならステップS9でコンベアライン11を停止する。その後、被搬送部材はコンベアライン12を通過したかをステップS10で判断し、「Y」ならステップS11で荷払い時間は、正常範囲内かを見て、「Y」ならステップS12で、コンベアライン12を停止させる。
【0011】
なお、ステップS8とステップS11で「N」なら、予測より旧系統のコンベラインの荷払いに時間がかかったとして、ステップS13で切替異常信号を発生し、系統の切替を停止するようにしている。また、ステップS2、S7、S10で「N」なら処理が「Y」になるまで繰り返す。
【0012】
上述したコンベアライン設備には、図示しないが、被搬送部材検出用のセンサが設置されていて、コンベアライン運転中、荷払いに要する時間とを組み合わせて被搬送部材のトラッキングを行い、起動タイミングの決定や異常検出等の条件に使用するようにしている。
【0013】
【発明の効果】
以上述べたように、この発明によれば、コンベア設備における新旧系統のコンベアラインを運転中に切り替えるときの時間ロスを無くして操業効率の向上を図ることができる利点がある。

BACKGROUND OF THE INVENTION
The present invention relates to a conveyor line system switching control method in a conveyor facility.
[0002]
[Prior art]
As shown in FIG. 3, in the conveyor line system switching control method in the conveyor facility in which the members to be transported on the conveyor lines of the old and new systems are transferred to the common conveyor line by switching the conveyor line, the conveyor line is changed to the Y shape. During operation of the old system conveyor lines 11, 12, 13 shown on the left side of the figure, the system is connected to the new system conveyor lines 14, 15, 13 (the conveyor line 13 is the old and new common conveyor line) shown on the right side of the figure. A method of operating by switching control is adopted. In this case, switching from the old system conveyor line to the new system conveyor line is controlled as follows by a switching command from a computer or the like.
[0003]
First, the conveyor line 11 is paid out by a switching command (the time for loading is counted by a timer, and is stopped after counting up). Thereafter, after the conveyor line 12 is stopped, the conveyor line 15 is activated, the conveyor line 15 is activated, and the conveyor line 14 is activated (sequence start) when the timer expires. When the start-up starts the conveyor line 14 and the timer expires (after starting the sequence), the start-up of the new system conveyor line is completed.
[0004]
[Problems to be solved by the invention]
In the conveyor line system switching control method during the operation of the conveyor equipment configured as described above, the new system is basically constructed after the unloading of the old system (conveyor line 11-conveyor line 12-conveyor line 13) is completed. Since (conveyor line 14-conveyer line 15-conveyer line 13) is activated, there is a lot of time loss from the completion of payout of the old system to the completion of activation of the new system, which is not efficient. In particular, when there are many conveyor lines upstream of the conveyor line 11 and the conveyor line 14, there is a possibility that a long time is consumed until the start-up of the new system is completed, and there is a problem that the operation efficiency is lowered.
[0005]
The present invention has been made in view of the above circumstances, and provides a conveyor line system switching control method in conveyor equipment that eliminates time loss at the time of switching during operation of old and new system conveyor lines and improves operational efficiency. Is an issue.
[0006]
[Means for Solving the Problems]
In order to achieve the above object, the present invention provides a conveyor line system switching control method in a conveyor facility in which a member to be transported on a conveyor line of two old and new systems is transferred to a common conveyor line by switching the conveyor line.
A first process in which a switching command is given to the old and new system conveyor lines, and a second process that reads the time to complete the unloading of the old system conveyor line when the switching command is given, and a conveyed object on the new system conveyor line A third step for reading the time for the members to reach the common conveyor line, a fourth step for calculating a difference between the time read in the second step and the time read in the third step, and the fourth step The fifth step of predicting the start timing time of the new system based on the time calculated in step 6 and the sixth step of stopping the conveyor line of the old system after unloading if the new system conveyor line is started in this fifth step A process ,
In the sixth step, it is determined whether the member to be transported on the conveyor line of the old system has passed the conveyor line, and if it has passed, it is checked whether the unloading time is within the normal range. If the conveyor line of the system is stopped and it is not within the normal range, it will take a long time to unload the conveyor line of the old system than predicted, and it will generate a switching error signal and stop the switching of the system. is there.
[0007]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a process explanatory diagram of a switching control method showing an embodiment of the present invention. In FIG. 1, 21 is a first process in which a switching command is given from a control device such as a computer (not shown) to a conveyor line of an old and new system. is there. When a switching command is given to the conveyor line from the first step 21, the second step 22 reads the time for completing the unloading of the conveyor line 11 and the conveyor line 12 in the old system. Further, when the switching command is given, the time required for the transported member on the conveyor line in the new system to reach the common conveyor line 13 is read in the third step 23.
[0008]
The difference between the time read in the second step 22 and the time read in the third step 23 is calculated in the fourth step 24, and the start timing time of the new system is predicted in the fifth step 25. . By this prediction, the conveyor line 15 is activated at the timing when the transported member on the conveyor line 14 reaches the conveyor line 15. If the conveyor line 15 is activated, the conveyor lines 11 and 12 of the old system are sequentially stopped at the sixth step 26 after the cargo is discharged.
[0009]
Next, the operation of the switching control method will be described with reference to the flowchart shown in FIG. First, a system switching command is issued from the first step 21 to the old and new conveyor lines (S1). It is determined in step S2 whether or not there is a switching command. If “Y”, the completion time of the shipment in the second step 22 is read (S3). Thereafter, in a third step 23, the time required for the members to be transported on the new conveyor lines 14 and 15 to reach the common conveyor line 13 is read in step S4.
[0010]
In the fourth step 24, the difference between the time read in step S3 and the time read in step S4 is taken in step S5, and the start timing of the new system conveyor line is predicted in step S6 (fifth step). 25). The conveyor lines 14 and 15 are activated based on this prediction. Thereafter, in step S7, it is determined whether the transported member on the conveyor line 11 has passed the conveyor line 11. If “Y”, in step S8 it is determined whether the unloading time is within the normal range, and “Y”. If so, the conveyor line 11 is stopped in step S9. Thereafter, it is determined in step S10 whether the member to be transported has passed the conveyor line 12. If “Y”, it is determined in step S11 whether the unloading time is within the normal range. If “Y”, the conveyor line is determined in step S12. 12 is stopped.
[0011]
If “N” in step S8 and step S11, it is assumed that it took time to unload the conveyor of the old system from the prediction, and a switching abnormality signal is generated in step S13 to stop the switching of the system. . If “N” in steps S2, S7, and S10, the process is repeated until “Y”.
[0012]
Although not shown in the drawings, the conveyor line equipment described above is equipped with a sensor for detecting a member to be transported, tracking the member to be transported in combination with the time required for unloading during the conveyor line operation, and It is used for conditions such as determination and abnormality detection.
[0013]
【The invention's effect】
As described above, according to the present invention, there is an advantage that the operation efficiency can be improved by eliminating the time loss when the old and new conveyor lines in the conveyor facility are switched during operation.
