本発明はセメント混和物押出成形品の搬送方法に関する
ものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for conveying cement mixture extrudates.
セメント系建材をセメント混和物の押出成形により成形
することが公知であり、この場合、押出機から出てくる
成形品を搬送するのに、第１図に示すように、押出機１
１から出てくる成形品ｐｔを補助コンベア２１で受取り
、この受取った成形品を主コンベア３１によって搬送す
る方法が用いられている。It is known that cement-based building materials are formed by extrusion molding of a cement mixture. In this case, as shown in FIG.
A method is used in which the molded product pt coming out of the molded product 1 is received by the auxiliary conveyor 21 and the received molded product is conveyed by the main conveyor 31.
この方法においては、補助コンベア２１に速度検出器４
１を設けて、成形品の押出速度を検出し、この検出量で
主コンベア３′の速度を制御して、主コンベア３′の速
度を成形品の押出速度に同期させている。In this method, a speed detector 4 is installed on the auxiliary conveyor 21.
1 is provided to detect the extrusion speed of the molded product, and control the speed of the main conveyor 3' based on this detected amount, thereby synchronizing the speed of the main conveyor 3' with the extrusion speed of the molded product.
ところで、第１図に示すように、主コンベア３１と補助
コンベア２１とは成形品を介して負荷的に連結されてお
り、また、補助コンベア２／は僅かの負荷の変動でも、
その変動が速度変化となって現われる特性を有する。By the way, as shown in FIG. 1, the main conveyor 31 and the auxiliary conveyor 21 are connected through a molded product in a load-bearing manner, and the auxiliary conveyor 2/ is connected even with a slight change in load.
It has a characteristic that the fluctuation appears as a speed change.
而して、第１図において、主コンベア３１がα係の誤差
率で同期されるものとすると、補助コンベア２１の検出
速度が■のとき、主コンベア３１の同時速度が（ｌ＋α
）■となり、この速度に補助コンベア２１の速度が規制
されて、補助コンベア２／の検出横変が（ｌ＋α）■と
なり、その結果、主コンベア３１の同期速度がｖ（ｉ＋
α）２となり、最終的には、ある速度■。In FIG. 1, assuming that the main conveyor 31 is synchronized with an error rate of α, when the detected speed of the auxiliary conveyor 21 is ■, the simultaneous speed of the main conveyor 31 is (l+α).
)■, the speed of the auxiliary conveyor 21 is regulated to this speed, the detected lateral displacement of the auxiliary conveyor 2/ becomes (l+α)■, and as a result, the synchronous speed of the main conveyor 31 becomes v(i+
α)2, and finally a certain speed■.
となる。而るに、最終的な同期速度■。becomes. Finally, the final synchronization speed ■.
になるまでにはかなりの時間を要し、この間、補助コン
ベア２１と主コンベア３１との間においてセメント押出
成形品が引張り乃至は、圧縮を受け、セメント成形品の
性状、特に密度が長い範囲にわたって変化するといった
不具合が生じる。During this time, the cement extrusion molded product is subjected to tension or compression between the auxiliary conveyor 21 and the main conveyor 31, and the properties of the cement molded product, especially the density, change over a long range. Problems such as changes occur.
従って、補助コンベアと主コンベアとの速度を早期に一
致させることが必要である。Therefore, it is necessary to quickly match the speeds of the auxiliary conveyor and the main conveyor.

。The method for conveying a cement mixture extrusion molded product according to the present invention includes:
This is a method invented in view of the above points, in which a cement mixture is extruded using an extruder, the extruded product is conveyed by a first conveyor and a second conveyor that are close to each other, and
In the method of synchronizing the second conveyor with the first conveyor by detecting the speed of the conveyor, the distortion state of the molded product between the first conveyor and the second conveyor is detected, and the second conveyor is
This method is characterized by modifying the speed of the conveyor.
以下、図面により本発明を説明する。The present invention will be explained below with reference to the drawings.
′第２図において１は押出機、Ｐはセメント混和
物の押出成形品である。'In Fig. 2, 1 is an extruder, and P is an extrusion molded product of cement mixture.
２は第１コンベアとしての補助コンベア、３は第２コン
ベアとしての主コンベアである。2 is an auxiliary conveyor as a first conveyor, and 3 is a main conveyor as a second conveyor.
４は第１コンベア２に設けた速度検出器である。4 is a speed detector provided on the first conveyor 2.
５は第２コンベアの制御駆動部であり、第１コンベア２
の検出速度Ｖに対し、誤差率αで第２コンベア３が同期
駆動される。5 is a control drive unit of the second conveyor, and the first conveyor 2
The second conveyor 3 is driven synchronously with the detected speed V at an error rate α.
而して、上記の制御機構のみでは、最終的な同期速度Ｖ
。Therefore, with only the above control mechanism, the final synchronous speed V
.
に達するまでに長期間を要することは前述した通りであ
る。As mentioned above, it takes a long time to reach this point.
第２図において、６は第１コンベアと第２コンベア３と
の間に設けたタッチロールであり、成形品の表面に接触
されている。In FIG. 2, 6 is a touch roll provided between the first conveyor and the second conveyor 3, and is in contact with the surface of the molded product.
このタッチロール６においては、第１コンベア２と第２
コンベア３との間の成形品が長手方向に圧縮されると、
その成形品が増肉される結果、上方向に移動し、一方、
同上成形品が長手方向に引張られると、その成形品が減
肉される結果、下方向に移動する。In this touch roll 6, the first conveyor 2 and the second conveyor
When the molded product between the conveyor 3 is compressed in the longitudinal direction,
As a result of the thickening of the molded part, it moves upward;
When the molded article is pulled in the longitudinal direction, the molded article is thinned and moves downward.
而るに、第２コンベア３の同期に上記した誤差率αが存
在する場合、第１コンベア２と第２コンベア３との間の
成形品には引張り（誤差率がプラス誤差の場合）、また
は圧縮（誤差率がマイナス誤差の場合）が作用し、タッ
チロール６が下方向または上方向に移動する。Therefore, if the above-mentioned error rate α exists in the synchronization of the second conveyor 3, the molded product between the first conveyor 2 and the second conveyor 3 will have tension (if the error rate is a positive error), or Compression (when the error rate is a negative error) is applied, and the touch roll 6 moves downward or upward.
上記タッチロール６においては、下方向また上方向移動
量に応じそ信号を発生し、この信号が第２コンベア３の
制御駆動部５に送入され、第２コンベア３の速度が上記
最終的な同期速度に向って、減速または増速修正される
。The touch roll 6 generates a signal according to the amount of downward or upward movement, and this signal is sent to the control drive unit 5 of the second conveyor 3, so that the speed of the second conveyor 3 is adjusted to the final speed. The speed is modified to slow down or speed up toward the synchronous speed.
従って、第２コンベア３の同期が速められる。Therefore, the synchronization of the second conveyor 3 is accelerated.
上述した通り、本発明に係るセメント混和物押出成形品

押出成形品の性状変動を排除できる。As described above, according to the method of conveying a cement mixture extrusion molded product according to the present invention, the second conveyor can be synchronized with the first conveyor in a short time, and therefore, the above-mentioned cases where synchronization takes a long time can be achieved. This eliminates the wide range of variations in properties of extruded cement mixture products.
