る。 (Industrial Application Field) The present invention relates to a material mixing and supplying device for mixing and supplying recycled material and new material in an in-line molding machine such as a stamping molding line or a vacuum-pressure molding line. . (Prior art) Conventionally, when producing products from resin molding materials by stamping molding or vacuum-pressure molding,
There is an inline method. First, recycled material and new material are mixed by a material mixing and supplying device and fed to an extruder, and the extruder melts and extrudes the mixed resin material to form a sheet plate. Then, this sheet plate is subjected to stamping molding, vacuum pressure forming, etc., and further trimming processing is performed to produce a product. Further, the scrap material produced by the trimming process is crushed by a crusher and returned to the material mixing and supplying device as recycled material, where it is mixed with new material and used. These operations are automatically and consistently performed on the same line. In addition, when extrusion molding is performed by mixing recycled material and new material in this way, the fluidity of the recycled material and new material differs when melted, so the mixing ratio of recycled material and new material may vary. The fluidity changes, which in turn changes the extrusion rate, which greatly affects the thickness of the sheet board. Therefore, during the same molding, it is necessary to keep the variation in the mixing ratio within ±10%, which is a range that does not affect the thickness of the sheet board. Furthermore, since the amount of recycled material changes depending on the yield of the product, the mixing ratio must also be adjusted for each product depending on the amount of recycled material. This preparation work was performed by an operator adjusting the material mixing and supplying device when replacing the mold. (Problems to be Solved by the Present Invention) However, adjusting the mixing ratio of recycled material and new material is time-consuming, and if this is forgotten, a serious problem will occur. For example, if you forget to adjust the mixing ratio and mold a product with an extremely high yield, there will be less scrap material, which means less recycled material will be returned, so the recycled material will decrease, and when it runs out, only new material will be used. It will be molded. This causes the problem that the quality of the product deteriorates because the thickness of the product changes as described above. On the other hand, if you forget to make adjustments and mold a product with an extremely low yield, the amount of recycled material will increase because there is a lot of scrap material, which can lead to equipment failures such as overflow from the tank or material clogging in piping. A problem arises. An object of the present invention is to provide a material mixing and supplying device that automatically changes the mixing ratio of recycled material and new material to perform stable extrusion molding, thereby streamlining the process and improving product quality. It is in. (Means for Solving the Problems) As a means for solving the above problems, the present invention provides a recycled material hopper and a new material hopper in parallel, and a predetermined number of recycled material hoppers are provided on the inner wall of the recycled material hopper. Level switches for detecting the remaining amount of the recycler are arranged in series at appropriate intervals along the vertical direction, and a measuring drum that controls the amount of material discharged from the recycled material hopper and the new material hopper according to the detection signal of the level switch is also regenerated. A material discharge port is provided for a material hopper and a new material hopper. (Function) With this configuration, even if products with different yields are molded, the level switch installed in the recycled material hopper detects the increase or decrease in recycled material, and the level switch installed in the recycled material hopper detects the increase or decrease in the recycled material, and the material discharge ports of the recycled material hopper and new material hopper are The number of rotations of the provided measuring drums is controlled respectively. Since this metering drum adjusts the amount of material discharged by rotating the drum, recycled material and new material can be supplied at any mixing ratio by controlling the number of rotations. (Example) An example of the present invention will be described below with reference to the drawings. The attached figure is a system diagram of an in-line molding machine using the material mixing and supplying device 1 of the present invention. This material mixing and supplying device 1 is composed of a recycled material hopper 2 and a new material hopper 3, which are provided in parallel. An upper limit level switch 4, a first intermediate level switch 5, a second intermediate level switch 6, and a lower limit level switch 7 are sequentially provided on the inner wall of the recycled material hopper 2 from above in the vertical direction. The mounting heights of these level switches may be determined as appropriate, but in this embodiment, the lower limit level switch 7 is located at a position 101 volumes from the lower end of the recycled material hopper 2.
The second intermediate level switch 6 is at a volume position from the lower limit level switch 7 to 93, the first intermediate level switch 5 is at a volume position from the second intermediate level switch 6 to 93, and the upper level switch 4 is at a volume position from the first intermediate level switch 5. 186 volume positions each. Material discharge ports 2a and 3a are provided at the lower ends of the recycled material hopper 2 and the new material hopper 3, respectively. are closely connected to each other. This recycled material measuring drum 8 has a concave portion 8a,
8a... along the outer periphery is rotatably provided by a speed control motor (not shown), and similarly, a new material measuring drum 9 is provided.
Also, a drum 9b having recesses 9a, 9a, . . . provided along its outer periphery is rotatably provided by a speed control motor (not shown). The material enters these recesses 8a, 9a through the discharge ports 2a, 3a, and rotates to discharge the material downward, and by changing the number of rotations, the discharge amount per unit time can be controlled. It is something that can be done. The level switch and these recycled material weighing drum 8 and new material weighing drum 9 are connected by a sequence circuit, and the materials from the recycled material hopper 2 and the new material hopper 3 are adjusted according to the signals from each level switch. Emissions are controlled and the mix ratio of recycled and new materials is adjusted. Here, the mixing ratio of recycled material and new material is set in five stages, A to E, as shown in Table 1.

The mixing ratio of A and E may be controlled by controlling the mixing ratio of C and D, but the mixing ratio of A and E is set in consideration of the case where a product with an extremely high yield or a product with an extremely small yield is to be molded. Next, the relationship between this mixing ratio and the material mixing and supplying device 1 will be explained. First, the recycled material is put into the recycled material hopper 2 between the first intermediate level switch 5 and the second intermediate level switch 6, and the mixing ratio of C in Table 1 (recycled material
The mixed material is supplied by controlling the recycled material measuring drum 8 and the new material measuring drum 9 so that the mixed material is 65% and the new material is 35%. For example, when a product with a low yield is molded here, the amount of recycled material remaining in the recycled material hopper 2 decreases because less recycled material is returned. Then, the second intermediate level switch 6 detects,
The recycled material measuring drum 8 and the new material measuring drum 9 are controlled so that the mixing ratio of D (55% recycled material, 45% new material) is achieved, thereby reducing the mixing ratio of recycled material and supplying it. Reduce the amount and use recycled material hopper 2
This prevents the amount remaining in the battery from decreasing. Here, since the yield of most products is within ±10%, it is sufficient to set the mixing ratio to B, C, and D, and the quality of the product is hardly affected by the mixing ratio of ±10%. This has been experimentally confirmed. Next, Table 2 shows yield selection modes provided for products with extremely large or extremely small yields.

る。[Table] For example, when molding a product with an extremely high yield, by selecting one of the three modes, materials can be supplied in the ranges C, D, and E, where the mixing ratio of recycled materials is small, and the yield can be increased. When molding an extremely small product, by selecting mode 1, materials are supplied in the ranges A, B, and C, which have a large mixing ratio of recycled materials. As described above, the amount of recycled material in the recycled material hopper 2 is detected based on the yield, and the mixing ratio of recycled material and new material is variably controlled by the measuring drum. I try to keep the amount of material remaining constant. Next, the structure and operation of an in-line molding machine using this material mixing and supplying device 1 will be explained. A predetermined amount of recycled material and new material discharged from the recycled material hopper 2 and the new material hopper 3 are collected together in an inverted conical tank 10 provided below, and are transferred to a cyclone of an extruder 12 by a pressure blower 11. 13. Here, 14 is a level switch for detecting material clogging in the tank 10. The material is then separated from the pumping air in a cyclone 13 and sent into an extruder hopper 15. In the extruder hopper 15 , the recycled material and the new material are agitated by an agitator 16 to a uniform state, and then supplied to the extruder 12 . Then, a sheet plate is produced by extrusion molding (not shown), and this sheet plate is subjected to stamping molding or vacuum-pressure forming, and then trimmed to produce a product. On the other hand, the scrap material produced by the trimming process is crushed into recycled material by a crusher 17. Then, this recycled material is transferred to a cyclone 19 provided above the recycled material hopper 2 by a pressure-feeding blower 18.
The recycled material is returned to the recycled material hopper 2 via the recycled material hopper 2. New material is supplied from the new material storage tank 20 into the new material hopper 3 via the cyclone 21 provided above the new material hopper 3, but the upper limit set on the inner wall of the new material hopper 3 The lower limit level switch 23 of the level switch 22 controls the supply amount from the new material storage tank 20 so that a predetermined amount is always contained. (Effects of the Invention) The present invention automatically variably controls the mixing ratio of recycled material and new material even when molding products with different yields, eliminating the need for manual labor and streamlining the process. Equipment failures such as overflow or material clogging in piping are completely eliminated. In addition, since the mixing ratio is variably controlled within a range that does not affect quality, products with stable quality can be provided.
