本発明はゴム混練ミキサに不定形ゴムブロック゛及び添
加剤を供給する方法に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for feeding amorphous rubber blocks and additives to a rubber kneading mixer.
Ｒ８Ｓ＃３等の天然ゴムは、第２図に示す如く、形状が
一定せず、且つ１個当りの重量が１００ユ程度の大きさ
であり、このままでは混練ミキサに投入できない。従っ
て、第３図の如く複数個に切断して使用している。As shown in FIG. 2, natural rubber such as R8S#3 has an irregular shape and a weight of about 100 units per piece, so it cannot be put into a kneading mixer as it is. Therefore, it is used by cutting it into a plurality of pieces as shown in FIG.
この切断後の小形ゴムブロックの重量は各ブロックで異
なるため、従来は各小形ゴムブロックを人手で計重し、
この小形ゴムブロックを更に人手で切断して最終調整を
行ない、所定重量のゴムブロックを混練ミキサに投入し
ている。The weight of each small rubber block after cutting is different for each block, so conventionally, each small rubber block was weighed manually.
This small rubber block is further manually cut to make final adjustments, and the rubber block of a predetermined weight is put into a kneading mixer.
前述の従来技術は、混練ミキサへの投入に先立ち、人手
によるダムブロックの計量、更に人手によるゴムブロッ
クの切断が必要であり、混練ミキサの操作の全自動化を
達成できない等の問題点がある。The above-mentioned conventional technology requires manual weighing of the dam block and manual cutting of the rubber block prior to feeding into the kneading mixer, and has problems such as not being able to fully automate the operation of the kneading mixer.
本発明は、ゴム混練ミキサの操作を自動化しうるゴムブ
ロック及び薬品の供給方法を実現することを目的とする
ものである。An object of the present invention is to realize a rubber block and a chemical supply method that can automate the operation of a rubber kneading mixer.
大型ゴムブロックを複数個に分割し、計量コンベアによ
り分割された小型ゴムブロックを計量する。A large rubber block is divided into a plurality of pieces, and the divided small rubber blocks are weighed by a weighing conveyor.
合計重量が所定の重量範囲に入る複数個の小型ゴムブロ
ックを混練ミキサに供給し、前記の合計重量に見合った
重量の薬品を混練ミキサに添加する。A plurality of small rubber blocks whose total weight falls within a predetermined weight range are supplied to a kneading mixer, and a chemical having a weight corresponding to the total weight is added to the kneading mixer.
分割された小型ダムブロックの重量は５〜１５ユであり
、通常使用されるゴム混線機の１バツチは約２００ｋｌ
Ｉである。複数個の小型ゴムブロックを１バツチ分集め
ると約１０ユのばらつきを生ずるが、ゴムブロック総重
量におけるこの程度の差異は混線機の処理に何等の影響
も生じない。The weight of a divided small dam block is 5 to 15 yu, and one batch of normally used rubber mixer is about 200 kl.
It is I. When a batch of a plurality of small rubber blocks is collected, a variation of about 10 units occurs, but this degree of difference in the total weight of the rubber blocks does not have any effect on the processing of the crosstalk machine.
また添加する薬品はダムブロック総重量に見合った量を
使用するので、ゴム製品の品質も変らない。従って、ゴ
ム製品の品質に悪影響を生ずることなくｄム混練ミキサ
の操作を自動化できる。Furthermore, since the amount of chemicals added is commensurate with the total weight of the dam block, the quality of the rubber product remains unchanged. Therefore, the operation of the d-mu kneading mixer can be automated without adversely affecting the quality of the rubber product.
第１図に示す、本発明が適用される混線設備を説明する
。The crosstalk equipment shown in FIG. 1 to which the present invention is applied will be explained.
Ａは混線機本体（混練ミキサ）で、２本のロータ１，１
′をチャンバ２内で回転させ、混線用ゴムブロックをホ
ツ／セ３より投入し、薬品をシュート４より添加し、ロ
ータ１，１′で混練させ、一定時間後、ドア５を開き排
出することにより、混線サイクルを完了する。A is the mixer main body (kneading mixer), which has two rotors 1 and 1.
' is rotated in the chamber 2, a rubber block for cross-conducting is introduced from the hotlet/separator 3, a chemical is added from the chute 4, the mixture is kneaded by the rotors 1 and 1', and after a certain period of time, the door 5 is opened and discharged. This completes the crosstalk cycle.
混練ミキサＡに供給する不定形ゴムブロックの計量につ
いてはまず、第３図の如く分割された、ゴムブロックＲ
ｏ、Ｒ，−一をフィードコンはア５上に一個ずつ並べ、
計量開始指令により、計量コンはアロ上へ順次移しかえ
てゆく。Regarding the measurement of the amorphous rubber block to be supplied to the kneading mixer A, first, the rubber block R is divided as shown in Fig. 3.
Arrange o, R, -1 one by one on feed controller A5,
In response to the command to start weighing, the weighing controllers are sequentially transferred onto the ARO.
１個送りのために、シリンダ７で、まずコンイア５の先
端のブロックＲＯが実線で示すし／ｚ−８で押さえられ
ており、シリンダ７を作動させレノ；−８を点線で示す
位置８′ にすると、ブロックＲＯはレバー８による保
持が解除され、計量コンはアロへ落下する。このときつ
ぎのブロックＲ１はレバー８′で保持され、落下しない
。In order to feed one piece, the block RO at the tip of the Conia 5 is first held down by the block RO shown by the solid line /z-8. When this is done, the hold on the block RO by the lever 8 is released, and the weighing condenser falls onto the RO. At this time, the next block R1 is held by the lever 8' and does not fall.
ついで、レバーを８の位置へ戻すと、ブロックＲ１はＲ
ｏの位置へ移り、再びレバーを８′の位置にすることで
、Ｒ１がコンはアロへ移る。計量コンベア６の計量値に
より、所要量に達するまで上記動作を繰返す。Then, when the lever is returned to position 8, block R1 moves to R.
By moving to the o position and moving the lever to the 8' position again, R1 moves from con to allo. The above operation is repeated until the required amount is reached according to the measured value of the weighing conveyor 6.
ここで、ブロックＲＯ＊ Ｒ１−一は、はぼ１個当り、
５〜１５ｋｇの重量であるため、実用的には、コンイア
６へ投入されたＩム重量の合計が所要計量値に対し、５
ゆ未満の差の場合は計量完とし、５に９以上の差がある
場合は次のブロックを投入する。Here, block RO*R1-1 is per piece of habo,
Since the weight is between 5 and 15 kg, in practical terms, the total weight of the im fed into the Conia 6 is 5 to 15 kg relative to the required weighing value.
If the difference is less than 1, the measurement is complete, and if there is a difference of 9 or more between 5 and 9, the next block is put in.
以上の如く、ブロックＲｏ、 Ｒ１−一の総重量は所要
値に対し、１０ユ程度のばらつきが出るため、各バッチ
毎のブロック総重量に対し薬品の比率を一定にするため
、薬品計量装置における薬品計量設定値を、上記プルツ
ク実計量値に合せ、毎回補正し、計量する。As mentioned above, the total weight of blocks Ro and R1-1 varies by about 10 yu from the required value, so in order to keep the ratio of chemicals to the total block weight for each batch constant, it is necessary to Correct the medicine measurement set value to match the above-mentioned pull-tuk actual measurement value, and then measure it each time.
この薬品は、ホッパ９に準備され、スクリューコンイア
１０で計量ホッパへ搬送し、上記の所要量まで計量し、
混練ミキサＡよりの指令により混練ミキサＡ内にシュー
ト４より投入される。This chemical is prepared in a hopper 9, transported to a weighing hopper by a screw container 10, weighed to the above-mentioned required amount,
The material is fed into the kneading mixer A from the chute 4 according to a command from the kneading mixer A.
上記で明らかな如く、ゴム計量サイクルと、薬品計量サ
イクルは、１サイクルずれるため、計量済ブロックをバ
ッファとして貯める投入コンイア１２が設置されている
。As is clear from the above, since the rubber measuring cycle and the chemical measuring cycle are shifted by one cycle, the input container 12 is installed to store the weighed blocks as a buffer.
通常使用される混練ミキサＡでの１バツチは約２００ｋ
ｌ？であり、混線性能としては１０チ程度バッチ重量の
ばらつきは実用上問題熱きため、上記で示す１０ユ程度
のブロック重量のばらつきは、薬品の比率が一定である
ため、混線品質に何ら悪影響を及ぼさない。One batch using the commonly used kneading mixer A is approximately 200k.
l? In terms of crosstalk performance, a variation in batch weight of about 10 units is a serious problem in practice, so the variation in block weight of about 10 units shown above does not have any negative impact on the crosstalk quality because the ratio of chemicals is constant. do not have.
