2. Description of the Related Art FIG. 10 shows an example of an apparatus for storing and automatically removing raw material fibers. The raw fiber is first opened in the blending and wobbling machine A, supplied to the seasoning room SN by an air flow, and seasoned for a predetermined time. Subsequently, it is similarly transferred to the stocker ST by an air flow. B indicates a transfer delivery fan. The operator attaches and detaches the card C from the stocker ST in response to a request signal from the supply mechanism F for the card C in the final process, and supplies the card C to the supply mechanism F manually or the like. S denotes a sensor for detecting the accumulated amount of the raw fiber in the supply mechanism F.

Reference numeral 16 denotes a spike blade which is attached to the spike roller 10 with a space therebetween, and reference numeral 17 denotes a raw fiber holding bar which is attached between the spike blades. The traveling mechanism 15 includes a driving wheel 20 a mounted on the traveling rail 14 and a driven wheel 20
b and a drive motor 21 for driving wheels.

The pressure receiving section 4 is a belt conveyor 27 having a width covering the opening on the lower surface of the housing and having a very small frictional resistance.
, One end is fixed to the lower part 29, 29 of the housing 2 and the other end is connected to a constant tension winding mechanism 34, 34 and receives a load of the raw fiber at an appropriate interval. The load receiving rollers 25 connected to each other are mounted in the width direction, and both ends of the load receiving rollers 25 protrude and are supported by a guide frame 26 mounted on the lower surface and side surfaces of the housing 2. When the frame member 13 is moved in one direction,
One belt conveyor 27 is wound by a winding mechanism with a constant tension, and the load receiving roller 25 is pushed by the frame member 13 and retracts to the side of the housing. When the frame member 13 moves to the other side, the belt conveyor 27 pulled out from the winding mechanism 34
And the load receiving roller 25 moves following the frame member 13.

The transport conveyor 5 is disposed below the scraping mechanism 3 and is driven in one direction. At the discharge side, a suction hood 31 connected to a suction fan 30 and a compression roll 32 are provided. If compression is not necessary depending on the type of fiber, the compression roll 32 may not be provided.

According to the present invention, only one raw fiber storage and automatic removal apparatus 1 may be used in place of the conventional stocker (see FIG. 10) using only one unit. FIG. 7 shows an example in which two raw fiber storage and automatic removal apparatuses 1 of the present invention are arranged in parallel and supplied to a card in the next step. However, reference numerals 2a and 2b denote housings of the devices 1 and 1, respectively, and reference numeral 40 denotes a switching valve for supplying raw fiber from the seasoning chamber S to the housings 2a and 2b.
Reference numeral 1b denotes a raw material fiber supply duct to the housings 2a and 2b.
D is a raw fiber supply duct for each of the cards C1, C2, C3,..., V1, V2, V3,.
A sensor S for detecting the amount of accumulated raw material fibers in 1, F2, F3,.
FIG. 10 shows an on-off valve that is opened and closed by an operation signal from FIG.

In the above configuration, when the raw material fiber is supplied to one of the housings 2a in advance, the housing 2a has a predetermined amount of the raw material fiber stored in the supply mechanism F1 for the card C1, for example, among the plurality of cards. When the value decreases below the value, the on / off valve V1 is opened by the detection signal and a supply signal is issued to the raw fiber storage and automatic removal apparatus 1.

Based on this, the scraping mechanism 3 on one housing 2a drives the spike roller 10 and the traveling mechanism 1
5 reciprocates on the lower surface of the housing. The raw fiber thus scraped is discharged onto the transfer conveyor 5, moved by the conveyor 5, sucked by the suction fan 30, and supplied to the required supply mechanism F1 via the supply duct D.

While transferring the raw fibers from the one housing 2a, the other housing 2b receives the raw fibers by switching the switching valve 40. Then, the machine in which the raw material fibers to be stored are full emits a signal to stop sending fan B.

Next, FIGS. 8 and 9 show a second embodiment. This indicates a deformation of the scraping mechanism 3 and the scraping mechanism 5
No. 0 includes the suction means 51 in the spike roller 10. This suction means includes a suction hood 52 covering the spike roller.
And the suction fan 30 connected to the suction hood 52 via a flexible tube 53. Other structures are the same as those of the previous example, and the same components are denoted by the same reference numerals and description thereof will be omitted.

With the above configuration, the transfer conveyor 5 in the first embodiment can be omitted.

It is needless to say that the method of supplying the card shown in FIG. 8 can be applied to this embodiment, and the explanation is omitted.

[0023]

As described above, according to the present invention, a raw cotton scraping mechanism is provided at the lower opening of the housing, and a pressure receiving portion is provided to cover the opening of the housing. The raw fiber in the housing is scraped from the bottom by the spike roller of the mechanism, preventing the raw fiber from remaining in the housing and deteriorating the quality of the raw fiber with a different mixing ratio that is newly supplied. Can be prevented. At this time, when the transport conveyor is arranged at the bottom of the housing, the raw fiber scraped by the spike roller can be efficiently collected and transported. In addition, the spike roller of the scraping mechanism is provided with a suction means, and when the scraped raw fibers are sucked by the suction means and supplied to the next process, the scattering of the raw fibers is prevented and the configuration is simplified. can do. Furthermore, when the above-mentioned housings are paired and the raw material fibers stored from one housing are supplied to the next process, and the raw material fibers are supplied to the other housing from the previous process, the receiving of the raw material fibers and the next Supply to the process can be performed continuously.
