機の場合はベントアツプのためベント孔が塞がり
ベント機能を無くしてしまう場合が多々生ずる。<Problems to be solved by the invention> Screw-type raw material supply devices are widely used due to the plasticizing ability of the molding machine and the need to supply raw materials without vent-up when the molding machine is a vent type. If some types of raw materials are supplied in excess of the processing capacity of the molding machine, overtorque may occur, making it impossible for the machine to operate, or, in the case of vent-type molding machines, the vent hole may become clogged due to vent build-up. There are many cases where functions are lost.

止を行うことを特徴とする原料供給装置とした。<Means for solving the problem> In order to achieve the above-mentioned object, the present invention rotates a screw inserted in a barrel, and performs molding through a raw material supply passage that communicates the barrel with a raw material supply port of a molding machine. In the raw material supply device for supplying raw materials into the machine, level detection means for detecting the amount of accumulated raw material is provided in the raw material supply passage, and the rotation of the screw rotation drive unit is stopped by a detection signal emitted by the detection means. This material supply device has the following characteristics.
〈実施例〉
次に本考案の１実施例を第１図により説明する

等の可視部２０を介して、蓄積原料のレベルを計
るようになつている。<Embodiment> Next, an embodiment of the present invention will be described with reference to FIG. This is a raw material supply device that supplies raw materials to the molding machine 16 via the molding machine 16. Reference numeral 17 denotes a motor for driving the screw 13 of the raw material supply device, and is equipped with a control device 18. 19 is a level detector using a capacitive proximity switch.
The amount of raw material accumulated in the raw material supply passage 15 is detected, and the level of the accumulated raw material is measured through a visible part 20 such as a glass window provided in the raw material supply passage 15.
以上のような構成となつており、何等かの原因
で原料供給装置１１からの供給原料が成形機１６
における処理量より多くなり原料供給通路１５へ
所定量が留つた場合、レベル検知器１９より信号
が発せられ、制御装置１８に作用し、原料の供給
を停止するべく、スクリユ１３の回転を停止する
ようになつている。 With the above configuration, for some reason the raw material supplied from the raw material supply device 11 is not supplied to the molding machine 16.
When the throughput exceeds the throughput and a predetermined amount remains in the raw material supply passage 15, a signal is issued from the level detector 19, which acts on the control device 18 to stop the rotation of the screw 13 in order to stop the supply of raw materials. It's becoming like that.
〈考案の効果〉
