Description
本発明は、ゴムチップの回収方法に関するものである。 The present invention relates to a method for collecting rubber chips.
ゴムチップは、例えば床材（例えば、特許文献１参照）やマット材（例えば、特許文献２参照）として使用されている。このゴムチップは、例えば、ゴムチューブを押し切り刃で切断して製造され、それを自動包装機に送って包装される（例えば、特許文献３参照）。 The rubber chip is used, for example, as a flooring material (for example, see Patent Document 1) or a mat material (for example, see Patent Document 2). This rubber chip is manufactured, for example, by cutting a rubber tube with a pressing blade, and is sent to an automatic packaging machine for packaging (see, for example, Patent Document 3).
しかしながら、自動包装機においてトラブルが発生すると、従来は、ベルトコンベアーから送り出されてくるゴムチップを系外に排出してスクラップ品として廃棄せざるを得なく、収益を悪化する原因となっていた。 However, when trouble occurs in the automatic packaging machine, conventionally, the rubber chips sent out from the belt conveyor have to be discharged out of the system and discarded as scrap products, which has been a cause of worsening profits.
従って、自動包装機のトラブル発生時に、ゴムチップを廃棄せず一時的にかわす方法が望まれていた。しかしながら、ゴムチップは特有の弾性を有しており、他のチップ状物質と異なり、タンク等に貯留すると内部で閉塞を起こす性質がある為、有用な回収手段がなかった。 Therefore, there has been a demand for a method of temporarily evacuating a rubber chip without discarding a rubber chip when trouble occurs in an automatic packaging machine. However, the rubber chip has specific elasticity, and unlike other chip-like substances, there is no useful recovery means because it has the property of clogging inside when stored in a tank or the like.
本発明の目的は、ゴムチップの自動包装機のトラブル発生時に、ゴムチップを廃棄せず効率的に回収する方法を提供することにあり、特に、途切れなくゴムチップを回収する方法を提供することにある。 An object of the present invention is to provide a method for efficiently collecting rubber chips without discarding them when trouble occurs in an automatic packaging machine for rubber chips, and in particular, to provide a method for collecting rubber chips without interruption.
本発明者らは上記課題を解決する手段として、カッターで裁断されたゴムチップをベルトコンベアーに乗せて自動包装機に供給する際に、ベルトコンベアーと自動包装機との間に、系外払い出しダンパー、及び、上部左側にゴムチップ受け入れ口、下部右側に系外排出口及び下部左側に系内回収口を備えたゴムチップ供給・排出カバーで囲まれた滞留ベルトコンベアーを介在させ、系外払い出しダンパーの開閉によりゴムチップの運搬を制御することで、上記の従来技術の課題を解決することができることを見出し、遂に本発明を完成するに至った。以下、本発明を詳細に説明する。 As a means for solving the above problems, the present inventors put a rubber chip cut by a cutter on a belt conveyor and supply it to an automatic packaging machine. Also, a staying belt conveyor surrounded by a rubber chip supply / discharge cover with a rubber chip receiving port on the upper left side, an external discharge port on the lower right side and an in-system recovery port on the lower left side is interposed, and by opening and closing the external discharge damper It has been found that the problems of the prior art can be solved by controlling the transportation of the rubber chip, and finally the present invention has been completed. Hereinafter, the present invention will be described in detail.
カッターで裁断されたゴムチップをベルトコンベアーに乗せて、自動包装機に供給する際に、ベルトコンベアーと自動包装機との間に、系外払い出しダンパー、及び、上部左側にゴムチップ受け入れ口、下部右側に系外排出口及び下部左側に系内回収口を備えたゴムチップ供給・排出カバーで囲まれた滞留ベルトコンベアーを介在させ、自動包装機の通常運転時には、系外払い出しダンパーを閉じて、ゴムチップを自動包装機に供給し、自動包装機のトラブルが発生したときに、系外払い出しダンパーを開放して、ゴムチップをゴムチップ受け入れ口から滞留コンベアーの上左側に供給し、ゴムチップを滞留コンベアーの右側（順方向）へ運搬して滞留させ、自動包装機のトラブルが解消した後で、滞留コンベアーの方向を反転させて、滞留しているゴムチップを左側（逆方向）へ運搬して系内回収口からタルク篩い装置へ戻すことを特徴とするゴムチップの回収方法により、自動包装機のトラブル発生時に廃棄していたゴムチップを回収することが可能となる。 When the rubber chips cut by the cutter are placed on the belt conveyor and supplied to the automatic packaging machine, the system is equipped with an external dispensing damper between the belt conveyor and the automatic packaging machine, the rubber chip receiving port on the upper left side, and the lower right side A retention belt conveyor surrounded by a rubber chip supply / discharge cover with an external system discharge port and an internal system recovery port on the lower left side is interposed, and during normal operation of the automatic packaging machine, the external discharge damper is closed and the rubber chip is automatically When a trouble occurs in the automatic packaging machine when the supply to the packaging machine occurs, the system dumping damper is opened and the rubber chip is supplied from the rubber chip receiving port to the upper left side of the staying conveyor, and the rubber chip is fed to the right side of the staying conveyor (forward direction). After the trouble of the automatic packaging machine is solved, the direction of the staying conveyor is reversed and staying The rubber chip that was discarded when a trouble occurred in the automatic packaging machine by collecting the rubber chip to the left (reverse direction) and returning it to the talc sieving device from the system recovery port. Is possible.
その際に、滞留したゴムチップが滞留コンベアーの滞留許容量を超えた場合には、そのゴムチップの超過分を系外排出口を通して系外へ排出することも可能であり、滞留しているゴムチップを左側（逆方向）へ運搬して系内排出口から系内へ戻してゴムチップを回収している最中に自動包装機にトラブルが発生した際には、再び滞留コンベアーを右側（順方向）へ回転させることにより、滞留コンベアー上がゴムチップで満たされるまで貯留を行うことが可能となる。 At that time, if the accumulated rubber chips exceed the retention capacity of the retention conveyor, the excess of the rubber chips can be discharged out of the system through the outside discharge port. If a trouble occurs in the automatic packaging machine while transporting it in the (reverse direction) and returning it from the system outlet to the system and collecting the rubber chips, rotate the staying conveyor to the right (forward direction) again. By doing so, it becomes possible to store until the staying conveyor is filled with rubber chips.
又、自動包装機のトラブル解消時に、ゴムチップを滞留コンベアーを通して左側（逆方向）に運搬して系内に回収する際の運搬速度を１〜５ｃｍ／分に調節して、製造ラインから新たに送られてくるゴムチップの単位時間当たりの供給量とのバランスを取りながらゴムチップを系内に戻すことにより、滞留コンベアー上にゴムチップが存在しないデッドスペースを生じさせない効率的なゴムチップの回収も可能となる。 Also, when solving troubles in automatic packaging machines, the rubber chip is transported to the left side (reverse direction) through the staying conveyor and adjusted to 1-5 cm / min for the transport speed when it is collected in the system. By returning the rubber chips to the system while balancing the supplied amount of rubber chips per unit time, it is possible to efficiently collect the rubber chips without causing a dead space where no rubber chips exist on the staying conveyor.
本願のゴムチップ回収方法での対象となるゴムチップとしては、汎用性で切断が容易なゴムであれば特に限定されるものではなく、例えば、クロロプレンゴムチップやブタジエンゴムチップなどが例示される。 The rubber chip to be used in the rubber chip collection method of the present application is not particularly limited as long as it is a versatile rubber that can be easily cut, and examples thereof include a chloroprene rubber chip and a butadiene rubber chip.
以下に、図１〜図４を参照して本願発明を具体的に説明する。 The present invention will be specifically described below with reference to FIGS.
図１は従来のゴムチップの自動包装方法を示し、図２は本発明における改良された自動包装方法でのゴムチップ回収方法を示す。 FIG. 1 shows a conventional method for automatically packaging rubber chips, and FIG. 2 shows a method for collecting rubber chips in the improved automatic packaging method of the present invention.
図１の従来のゴムチップの自動包装方法においては、自動包装機にトラブルが発生していない時は、タルク添加装置（１）で、固着防止剤としてタルクを添加されたゴムチップは、余分なタルクを取り除く為のタルク篩い装置（２）を経て、バケットコンベアー（３）で上方へ運搬され、閉じている系外払い出しダンパー（４）を経てからベルトコンベアー（５）への供給口（６）から供給されて運搬され、自動包装機（７）に供給され包装される。 In the conventional automatic packing method of rubber chips shown in FIG. 1, when no trouble occurs in the automatic packing machine, the rubber chips to which talc is added as an anti-sticking agent in the talc adding device (1) After passing through the talc sieving device (2) for removal, it is transported upward by the bucket conveyor (3), passes through the closed external dumping damper (4), and then supplied from the supply port (6) to the belt conveyor (5) Then, it is transported and supplied to the automatic packaging machine (7) for packaging.
自動包装機にトラブルが発生すれば、系外払い出しダンパー（４）を開けて、ゴムチップを系外排出槽（８）へ送付し、フレコンとして系外へ搬出するのが従来の方法であり、排出されたゴムチップはスクラップ品として処分されていた。 If trouble occurs in the automatic packaging machine, the conventional method is to open the system discharge damper (4), send the rubber chips to the system discharge tank (8), and carry it out as a flexible container. The rubber chips were discarded as scrap products.
本発明では、図２に示される様に、系外払い出しダンパー（４）と系外排出槽（８）との間に、ゴムチップ供給・排出カバー（９）で囲まれた滞留ベルトコンベアー（１０）を設置し、この装置には、上部左側にゴムチップ受け入れ口（１１）、下部右側に系外排出口（１２）及び下部左側に系内排出口（１３）を備えている。 In the present invention, as shown in FIG. 2, the staying belt conveyor (10) surrounded by the rubber chip supply / discharge cover (9) between the system discharge damper (4) and the system discharge tank (8). This apparatus is provided with a rubber chip receiving port (11) on the upper left side, an external discharge port (12) on the lower right side, and an internal discharge port (13) on the lower left side.
自動包装機の通常運転時には、系外払い出しダンパー（４）を閉じて、ゴムチップは、ベルトコンベアーへの供給口（６）からベルトコンベアー（５）に供給されて運搬され、自動包装機（７）に供給され包装される。 During normal operation of the automatic wrapping machine, the extra-system dispensing damper (4) is closed, and the rubber chips are fed from the supply port (6) to the belt conveyor to the belt conveyor (5) and conveyed to the automatic wrapping machine (7). Supplied and packaged.
自動包装機にトラブルが発生したときのゴムチップの回収方法を、図３及び図４を用いて以下に説明する。 A method of collecting rubber chips when trouble occurs in the automatic packaging machine will be described below with reference to FIGS.
自動包装機にトラブルが発生したときは、系外払い出しダンパー（４）（図２参照）を開けて、ゴムチップをゴムチップ受け入れ口（１１）を通して、滞留ベルトコンベアー（１０）に供給し、ゴムチップを滞留コンベアーの右側（順方向）へ運搬して滞留させる。 When trouble occurs in the automatic packaging machine, open the extra dumping damper (4) (see Fig. 2) and supply the rubber chip through the rubber chip receiving port (11) to the staying belt conveyor (10) to retain the rubber chip. Transport to the right side of the conveyor (forward direction) and stay.
この際、この滞留コンベアーの滞留能力を超えた場合は、超えたゴムチップを系外排出口（１２）を通して排出させ、系外排出槽（８）（図２参照）へ供給して、スクラップとして処分する。 At this time, if the staying capacity of the staying conveyor is exceeded, the excess rubber chips are discharged through the outside discharge port (12) and supplied to the outside discharge tank (8) (see FIG. 2) for disposal as scrap. To do.
自動包装機のトラブルが解消した時、滞留コンベアー（１０）の運搬方向を反転させて、滞留しているゴムチップを左側（逆方向）へ運搬して系内排出口（１３）を通して、タルク篩い装置（２）（図２参照）へ供給して系内へ戻す。 When the trouble of automatic packaging machine is solved, the conveying direction of the staying conveyor (10) is reversed, the staying rubber chips are transported to the left side (reverse direction) and passed through the system outlet (13), and the talc sieve device (2) Supply to (see FIG. 2) and return to the system.
この際、自動包装機のトラブル発生時におけるベルトコンベアーの順方向への運搬速度を遅くすると、滞留時間がかかり過ぎて、自動包装機のトラブルが解消する間に滞留が終了せずに、次回のトラブル発生時までに、空運搬が生じて、滞留ベルトコンベアー上にゴムチップがないデッドスペースが生じるので、なるべく自動包装機のトラブル発生時におけるベルトコンベアーの順方向への運搬速度を速く調整する。 At this time, if the conveyor speed in the forward direction of the belt conveyor at the time of trouble occurrence of the automatic packaging machine is slowed down, it will take too much residence time and the residence will not end while the trouble of the automatic packaging machine is resolved, By the time the trouble occurs, empty conveyance occurs and a dead space without rubber chips is generated on the staying belt conveyor. Therefore, the conveying speed in the forward direction of the belt conveyor should be adjusted as fast as possible when trouble occurs in the automatic packaging machine.
一方、自動包装機のトラブル解消時におけるベルトコンベアーの逆方向への運搬速度を速く調整すると、系内へ戻すゴムチップの単位時間当りの量が大きくなり、製造ラインから新たに送られてくるゴムチップの単位時間当たりの供給量とのバランスが崩れてベルトコンベアー（３）の運搬においてトラブルが発生しやすいので、自動包装機のトラブル解消時におけるベルトコンベアーの逆方向への運搬速度は、次のトラブルが発生するまでに系内へ滞留ゴムチップを全て戻すことが可能な範囲で、なるべく遅く調整する方が好ましい。 On the other hand, if the conveyor speed of the belt conveyor in the reverse direction is adjusted quickly when troubles in automatic packaging machines are resolved, the amount of rubber chips returned to the system per unit time increases, and the amount of rubber chips newly sent from the production line is increased. Since the balance with the supply amount per unit time is lost and troubles are likely to occur in the transportation of the belt conveyor (3), the transportation speed in the reverse direction of the belt conveyor when the trouble of the automatic packaging machine is solved is as follows. It is preferable to adjust as late as possible within a range in which all the staying rubber chips can be returned to the system before they are generated.
本願発明のゴムチップ回収方法により、自動包装機のトラブル発生時に、従来は系外へ廃棄していたゴムチップを回収することが可能となり、ゴムチップを滞留コンベアーを通して右側（順方向）に運搬させて滞留させる際の運搬速度、及び、ゴムチップを滞留コンベアーを通して左側（逆方向）に運搬してベルトコンベアーに供給する際の運搬速度を調節して、自動包装機のトラブルが繰り返し発生する際に、滞留ベルトコンベア上にゴムチップのデッドスペースが発生しないようにすることも可能となる。 With the rubber chip recovery method of the present invention, it is possible to recover rubber chips that were conventionally discarded outside the system when trouble occurs in the automatic packaging machine, and the rubber chips are transported to the right side (forward direction) through a retention conveyor and retained. When the trouble of the automatic packing machine occurs repeatedly by adjusting the transport speed and the transport speed when transporting the rubber chips to the left side (reverse direction) through the stay conveyor and feeding them to the belt conveyor, the stay belt conveyor It is also possible to prevent the dead space of the rubber chip from occurring on the top.
