Description of the Related Art Recently, various fiber raw materials having excellent characteristics and functions have been developed, and fiber products using them have been put into practical use. These fiber raw materials are often used as a mixture with other fiber raw materials rather than being used alone because they are expensive and have a composite function. Conventionally, when mixing plural kinds of fiber raw materials, an apparatus as shown in FIGS. 3A and 3B is used. That is, a plurality of fiber raw material supply devices 22a, 22b, 22c are installed at equal intervals along the conveyor 21, and each fiber raw material supply device 22a, 22b, 22c is equipped with a weighing hopper 23a, 23b, 23c. , A hopper 23 for weighing the fiber raw material in a weight corresponding to the mixing ratio of each fiber raw material
It is supplied to a, 23b, and 23c and weighed, and after weighing, it is dropped onto the conveyor 21 by its own weight and discharged. In this case, the transport conveyor 21 is driven intermittently, and during the stop, first, the weighed first fiber raw material 24a is fed from the weighing hopper 23a of the first fiber raw material supply device 22a on the most upstream side onto the transport conveyor 21. When it is dropped and discharged, and after the discharge, the conveyor 21 is driven to bring the first fiber raw material 24a to the position below the second fiber raw material supply device 22b and the conveyor 21 is stopped. Fiber material 24b is dropped onto the first fiber material 24a and discharged, and after the discharge, the conveyor 21 is driven to move the first and second fiber material 24a and 24b to the third fiber material supply device 22c. When the conveyor 21 stops at the bottom,
The third fiber raw material 24c is dropped and discharged from the third weighing hopper 23c onto the first and second fiber raw materials 24a and 24b. Pressure equalizing rollers 25a, 25b, 25c are installed downstream of the respective fiber raw material supply devices 22a, 22b, 22c, and evenly press the respective fiber raw materials 24a, 24b, 24c supplied on the conveyer 21 evenly.

できず、ロスタイムが発生する不具合もあった。When a plurality of fiber raw materials are mixed and spun or when a nonwoven fabric is produced, it is necessary to uniformly mix the respective fiber raw materials. In the conventional fiber raw material supply method, after measuring each fiber raw material to a predetermined mixing ratio by the weighing hopper, since it is dropped and discharged by its own weight onto the conveyor, the discharged fiber raw material becomes a heap state, This is leveled by a pressure equalizing roller, but there are differences in the properties and mixing ratio of each fiber raw material, and the size and position of the peaks formed on the conveyor are not the same, so a uniform thickness is obtained. It was difficult to level them. In particular, in the case of a fiber raw material having a low mixing ratio, it was more difficult to even the fibers by a pressure equalizing roller. for that reason,
Even in the next step of blending and opening, the mixture was not uniformly mixed, and there was a problem that uneven density of each fiber raw material occurred. Further, in the above conventional method, the supply of the fiber raw material to the weighing hopper,
For example, up to 95% is delivered in large quantities, and the remaining 5%
Is fed by a small amount to reach 100%, and when it reaches 100%, the supply of the fiber raw material is stopped, the bottom plate of the weighing hopper is opened, the fiber raw material inside is dropped and discharged onto the conveyor, and after the bottom plate is discharged. Since it closes and moves to the next weighing, and this kind of weighing operation is performed in the same way for all the fiber raw materials to be mixed, the feeding of the fiber raw material to the conveyor is batch type, and the conveyor must also be driven intermittently. Therefore, the fiber raw material cannot be continuously mixed and supplied, and there is a problem that loss time occurs.

に記載の繊維原料の混合供給装置。 6. The control means measures the weight of each fiber raw material supplied on each of the conveyors at each predetermined transport distance by the measuring means a plurality of times for each fiber raw material , and calculates an average value thereof. The average value and the target value are compared and calculated, and when the average value has an error with respect to the target value, the fiber raw material feeding amount of the fiber raw material supply means corresponding to the fiber raw material having the error is calculated. The fiber raw material supply amount of each fiber raw material supply means arranged downstream of the adjusted fiber raw material adjusting means is adjusted so that the error from the target value is eliminated, and at the same time, 6. It has a function of adjusting so that the respective mixing ratios become constant with respect to the amounts.
