値より大きく設計する。On the other hand, a hopper 3B is arranged below the supply port 27 through which the crushing runner is sent out. This hopper 3B is connected to a cyclone 38 by a pipe 37, and an ejector device i39 is interposed in the pipe 37. The ejector device 39 has a function of supplying compressed air supplied from the compressor to the pipe 37, sucking the crushing runner from the hopper 38, and forcefully feeding it to the cyclone 38. It will be done. Furthermore, the cyclone 38 has a function of separating the pressure-fed crushing runner from the air medium, and its size may be quite small in the case of a normal crushing runner.For example, the diameter of the pipe 37 is At 20 seconds, separation is theoretically possible with a diameter of 53 inches and a length of 1801 inches, but if it is too small, cleaning is inconvenient, so it is practically designed to be larger than the above values.

る。A runner supply pipe 40 extends downward from the lower end of the cyclone 38, and the tip of the runner supply pipe 40 faces into a mixer 42 provided above a molding machine 41. The mixer 42 has a conical lower part and is connected to the molding machine 41 via a raw material supply port 43. In the mixer 42, the runner supply pipe 40 has a plurality of supporting legs 40a extending from the tip expanded into a funnel shape.
A separate new material cyclone 44 is also connected to the mixer 42, which is supported by the peripheral wall of the mixer 42 via the supporting legs 40a (FIG. 2), via a new material supply port 45.

形機４１へと供給される。Runners produced during injection molding enter the input chute 22 by falling naturally from the conveyor 25. In the case of a molded product that requires post-processing such as gate cutting, the separated runners may be manually placed into the input chute 22, and the input runners are crushed by the crushing blade 26 to become crushed runners. The crushing runners are deposited at the bottom of the quantitative feeder 24 and received by the feeder 27, which supplies a predetermined amount to the supply port 28 and stores it in the hopper 36. The grinding runners that are not fed by the feeder 27 remain at the bottom. The crushing runners stored in the hopper 38 are
is pumped to the cyclone 38 by the ejector device 39,
After the air is separated there, it flows down to the mixer 42 via the runner supply pipe 40, is mixed with the new material flowing down from the new material cyclone 44 in the mixing a42, and is then supplied to the molding machine 41. .

Next, the feeder 27 is rotated in the opposite direction to remove the crushing runner remaining at the tip of the feeder 27. Next, compressed air is supplied from the cleaning nozzle 33, 34, 35 to each of the crushing blade 2B, feeder 27, and stirring blade 29c. The crushed runners attached thereto are washed and discharged from the discharge port 30 into the receiving box 4B. After completing this series of cleaning operations, different types of runners are introduced to prepare for the next molding.

小を図れる。(Effects of the Invention) Since the present invention is constructed as described above, when changing materials or changing colors, the crusher can It is possible to clean the inside of devices such as quantitative feeders, and a significant improvement in cleaning workability can be achieved. In addition, since there is no need to disassemble and clean it, there is no dust contamination for workers, which improves the environment. Furthermore, by mixing the crushing runner and new material on the molding machine side, the piping in the middle is only used for conveyance purposes, so it is sufficient to use not only small diameter piping but also a small blower. The flow path can also be shortened, reducing installation space.

良品の発生も減少する。There is no dust pollution and the environment is improved. Since there is less stagnation in the route to the mixer, there is less loss of material during color changes, etc. Also, because the distance from the mixer to the molding machine has been shortened, the mixed materials can separate due to the difference in falling speed. This also solves the problem of product defects, improving product uniformity and reducing the number of defective products.
