It is used to cut with high precision to a specified, constant length.
従来の切断装置、とくに前述した連続成形品の切断装置
は、成形品の進行ライン上に往復走行する台車を設置し
、この台車に成形品を固定するエアシリンダーなどのチ
ャック部と切断部とを設け。Conventional cutting equipment, especially the cutting equipment for continuous molded products mentioned above, is equipped with a cart that moves back and forth on the progress line of the molded product, and a chuck part such as an air cylinder that fixes the molded product to this cart, and a cutting part. Provided.
進行ライン上の前方には０台車に連結されてこれと一体
Ｃζ往復動する光電装置などの検尺部を設置して構成さ
れている。A measuring section, such as a photoelectric device, which is connected to the 0 carriage and reciprocates integrally with it in Cζ, is installed at the front of the traveling line.

送速度に同調して走行させ、その走行中に成形品を切断
するようになっている。When a continuous molded product passes through the child chuck section and the cutting section and its tip is detected by the photoelectric device in the measuring section, the signal activates the air cylinder in the chuck section to transfer the molded product to the cart. At the same time, the carriage is moved in synchronization with the transport speed of the molded product, and the molded product is cut while it is traveling.
この種の切断部ｒＩＩＩこおいて、チャック部化一般的
に使用されているエアシリンダーの許容動作時間のずれ
は０通常、１〜’／１００秒程度であるから。In this type of cutting section rIII, the deviation in the allowable operating time of the generally used air cylinder for the chuck section is usually about 1 to 1/100 seconds.
前述したように光電装置で成形品の先端を検出し。As mentioned above, the tip of the molded product is detected using a photoelectric device.
その信号によりエアシリンダーを作動させて成形品をチ
ャ、キングしても、第２図に示すように。Even if the air cylinder is activated by the signal to chuck or chuck the molded product, the result will be as shown in Figure 2.
切断される成形品１ｍｌの実際の長さｌｂｌは、規定さ

カッターの位１！！６’間の長さｔａｌよりも長くなる
ことが多い。The actual length lbl of 1 ml of the molded part to be cut is equal to the defined cutting length a), ie at position 8' of the optoelectronic device and position 1 of the cutter. ! It is often longer than the length tal between 6'.
さらに具体的に例示すれば、前記許容動作時間の誤差を
有するエアシリンダーを用い、成形品（−の平均的な移
送速度が毎秒６ｍであるとすると。To give a more specific example, suppose that an air cylinder having an error in the allowable operation time is used and the average transport speed of the molded product (-) is 6 m/s.
エアシリンダーが作動して成形品を固定した時点では、
前記動作時間のずれからして、成形品の先端は約１−２
”’だけ光電装置の位置から突出してしまうのである。When the air cylinder operates and fixes the molded product,
Judging from the above operating time difference, the tip of the molded product is approximately 1-2
``'' protrudes from the position of the photoelectric device.
他方、カッターの位置は定位置に固定されているから、
成形品はその突出分（Ｃ１だけ長（切断されることとな
り、高精度の切断ができないという問題点かあうたう
なお、前述した問題点は、往復走行する台車を有せず、
チャック部、切断部及び検尺部を固定させて設けた切断
装置においても、全く同様に生じている。On the other hand, since the cutter position is fixed in place,
The molded product has to be cut by the length of its protrusion (C1), so there is a problem that high-precision cutting cannot be performed.
The same problem occurs even in a cutting device in which a chuck part, a cutting part, and a measuring part are fixedly provided.
本発明は上記問題点を解決しようとするもので。The present invention aims to solve the above problems.
