本考案は、溶融ポリマーをノズルから押し出し、冷却固化後、カッターで切断 するポリマー造粒装置に関するものである。 The present invention relates to a polymer granulating apparatus in which a molten polymer is extruded from a nozzle, cooled and solidified, and then cut by a cutter.
【０００２】[0002]
溶融ポリマーを粒状化する場合、溶融ポリマーをノズルからストランド状に押 し出し、冷却固化後、カッターで切断するポリマー造粒装置が広く使用されてい る。 このような造粒装置において、ノズルからの押し出し量が変化した場合、粒状 物 (ペレット) の形状が変化するという問題があった。そして、ペレットの形状 を一定に保つには、作業員がペレットの形状を測定し、押し出し量の変化に応じ てカッター速度を調節する必要があった。このため、押し出し量の変化に対する 応答性が悪く、均一な形状のペレットを得ることは困難であった。 BACKGROUND ART When granulating a molten polymer, a polymer granulating device is widely used in which the molten polymer is extruded from a nozzle in a strand shape, cooled and solidified, and then cut by a cutter. In such a granulating apparatus, there is a problem that the shape of the granular material (pellet) changes when the amount of extrusion from the nozzle changes. Then, in order to keep the pellet shape constant, it was necessary for an operator to measure the pellet shape and adjust the cutter speed according to the change in the extrusion amount. For this reason, the responsiveness to changes in the extrusion amount was poor, and it was difficult to obtain pellets of uniform shape.
【０００３】 この問題を解決するものとして、ペレットの形状を自動的に測定する装置を設 け、その測定値によりカッター速度を調節するようにした装置が提案されている (特開平４−25408号)。しかし、この装置では、ペレットの形状が変化してから の応答であるため、形状不良のペレットが製品中に混入することは避けられなか った。As a solution to this problem, a device has been proposed in which a device for automatically measuring the shape of pellets is provided and the cutter speed is adjusted according to the measured value (Japanese Patent Laid-Open No. 4-25408). ). However, with this device, it was unavoidable that defective pellets were mixed into the product because the response was after the pellet shape had changed.

本考案は、上記の課題を解決するもので、その要旨は、溶融ポリマーをノズル から押し出し、冷却固化後、カッターで切断するポリマー造粒装置において、溶 融ポリマーをノズルへ送る配管に圧力検出端を設けるとともに、その検出圧力値 によりカッター速度を制御する調節計を設けたことを特徴とするポリマー造粒装 置にある。 The present invention solves the above-mentioned problems, and the gist thereof is a polymer granulating apparatus in which a molten polymer is extruded from a nozzle, cooled and solidified, and then cut by a cutter. In addition to the above, the polymer granulation apparatus is characterized in that a controller for controlling the cutter speed based on the detected pressure value is provided.
【０００６】 次に、本考案の装置について、図面により具体的に説明する。 図１は、本考案の装置の一例を示す概略説明図であり、１は溶融ポリマーをノ ズル２へ送る配管、３は圧力検出端、４はカッター速度調節計、５はカッター、 ６はペレットである。Next, the device of the present invention will be specifically described with reference to the drawings. FIG. 1 is a schematic explanatory view showing an example of the device of the present invention, 1 is a pipe for sending a molten polymer to a nozzle 2, 3 is a pressure detecting end, 4 is a cutter speed controller, 5 is a cutter, 6 is a pellet Is.
【０００７】 溶融ポリマーは配管１を通ってノズル２から押し出されるが、その流量が定常 値よりも多くなった場合、ノズル２での圧力損失が大きくなり、圧力検出端３で の圧力が定常値より上昇する。この検出圧力値の信号を調節計４に送り、調節計 ４からカッター５に信号を送り、カッター速度を増速させる。逆に、溶融ポリマ ーの流量が定常値より少なくなった場合には、ノズル２での圧力損失が小さくな るので、同様にしてカッター速度を減速させる。 このように、溶融ポリマーの流量変化を圧力変化により検出し、検出圧力値の 変化に即応してカッター速度を調節することにより、ペレットの形状を一定に保 つことができる。The molten polymer is extruded from the nozzle 2 through the pipe 1, but when the flow rate becomes larger than the steady value, the pressure loss at the nozzle 2 becomes large and the pressure at the pressure detection end 3 becomes a steady value. Rise more. A signal of this detected pressure value is sent to the controller 4, and a signal is sent from the controller 4 to the cutter 5 to increase the cutter speed. On the contrary, when the flow rate of the molten polymer becomes smaller than the steady value, the pressure loss at the nozzle 2 becomes small, and the cutter speed is similarly reduced. In this way, the pellet shape can be kept constant by detecting the flow rate change of the molten polymer by the pressure change and adjusting the cutter speed in response to the change in the detected pressure value.
【０００８】[0008]
本考案の装置によれば、ノズルからの押し出し量の変化に即応してカッター速 度を調節することができ、均一な形状のペレットを得ることができる。 また、溶融ポリマーの流量変化を安価な圧力検出端で検出するので、本考案の 装置は安価である。 According to the device of the present invention, the cutter speed can be adjusted in response to a change in the amount of extrusion from the nozzle, and pellets having a uniform shape can be obtained. Further, since the change in the flow rate of the molten polymer is detected by the inexpensive pressure detecting end, the device of the present invention is inexpensive.
