With the above configuration, when the fiber raw material 2 is taken out little by little and fed to the next stage, the fiber raw material 2 is first moved into the raw material storage space 1 while the machine frame 5 is moved to the backward end. supply and preserve.

The fiber raw material 2 can be easily supplied into the raw material storage space 1 by using a crane, a forklift, or the like.

The above-mentioned fiber raw material 2 may be, for example, raw cotton 2a after being opened into bales as shown in FIG. 1, or a mixed fiber raw material 2b consisting of different types of fiber raw materials A, B, C, etc. Also good.

Next, when the fiber raw material extracting machine 4 is started, the forward/reverse motor 8 is driven to rotate in the normal direction to move the machine frame 5 forward, and the front drive motor 22 is driven to rotate almost simultaneously with the forward movement of the machine frame 5. Spike lattice 14, Evener lattice 1
5 and the counter roller 18 are respectively rotated in the direction of the arrow X, and the forward/reverse rotation motor 26 is driven to rotate in the normal direction to rotate the beater roller 25 in the direction of the arrow X.

Further, the conveyor fan 29 is also rotationally driven.

As a result, the front part of the spike trusses 14 located on the advancing direction side of the machine frame 5 is pressed against the fiber raw material 2.

Therefore, the fiber raw material 2 in the raw material storage space 1 is scraped over almost the entire width by the spikes of the spike lattice 14 and transferred upward, and the fiber raw material transferred upward is scraped by the spikes of the evener lattice 15. The fibers are opened and the excess fiber raw material is removed to obtain a fiber raw material having a substantially constant thickness, and this constant thickness fiber raw material is transferred to the back side of the spike trusses 14.

The fiber raw material transferred to the back side is batted by the beater roller 25 and brushed off from the top of the spike trusses 14, and the brushed-off fiber raw material is sent above the hopper 28 by the counter roller 18. and is dropped into the hopper 28.

The fiber raw material dropped into this hopper 28 is
After being collected in a, the air is sucked together with air into the suction duct 30 by the suction force in the suction duct 30 by the conveyor fan 29, and the air is conveyed to another device or place for the next step.

As described above, the fiber raw material 2 stored in the raw material storage space 1 on the front side of the machine frame 5 is taken out little by little and continuously fed to the next step, and the machine frame 5 stores this fiber raw material 2. It is moved forward as it is taken out.

Thereafter, the machine frame 5 is moved to the forward end and the removal of the fiber raw material 2 from the raw material storage space 1 is completed. The next second fiber raw material 2 is supplied and left in the empty raw material storage space 1 that has been formed.

This supply of the fiber raw material 2 can be carried out at any time while the machine frame 5 is being moved forward as described above and the fiber raw material 2 is being taken out, so that workers engaged in other work can can be done in a short time using free time.

In addition, in this case, when the machine frame 5 is moved forward as described above, the spike trusses 14e located on the rear side of the machine frame 5 are stopped from rotating, so that It is possible to safely supply fiber raw materials to

Next, when the machine frame 5 is moved to the forward end, this is detected by a detection means such as a limit switch (not shown), and the rotational drive of the forward-reverse motor 8, the front drive motor 22, and the forward-reverse motor 26 is stopped. Immediately thereafter, the forward/reverse rotation motor 8 is now driven in the reverse direction to move the machine frame 5 backward.

Also, almost simultaneously with the backward movement of Riko's machine frame 5, the rear drive motor 22e is rotationally driven to rotate the spike trusses 14.
e. The easer lattice 15e and the counter roller 18e are rotated in the directions of the arrows, and the forward/reverse motor 26 is now driven in the reverse direction to rotate the debeater roller 2.
5 in the direction of arrow Y.

As a result, the front part of the spike trusses 14e is pressed against the fiber raw material 2 in the raw material storage space 1 for the second time.

Therefore, the fiber raw material 2 kept in the raw material storage space 1 is taken out little by little substantially continuously as the fiber raw material 2 is taken out by the forward movement of the machine frame 5, and is air conveyed to the next step. .

Thereafter, before the machine frame 5 is moved to the backward end and the removal of the fiber raw material 2 is completed, the fiber material is placed in the empty raw material storage space 1 formed in front of the machine frame 5 in the same manner as described above for the 33rd time. Let raw material 2 remain.

By repeating the above operations, the fiber raw material can be continuously supplied to the next step over a long period of time.

As described above, in this invention, by advancing the machine frame, the fiber raw material in the raw material storage space can be scraped off little by little and fed to the next stage. When it is desired to continuously supply the fiber raw material little by little to the next stage, by leaving a large lump of the fiber raw material in the raw material holding space and advancing the machine frame, the fiber raw material can be continuously supplied little by little to the next stage. This has the effect of efficiently supplying this fiber raw material to the next stage with less effort and effort.

In addition, even if the device is designed to scrape off the fiber raw material in the raw material storage space and supply it to the next stage by advancing the machine frame as described above, the raw material can also be scraped off when the machine frame is advanced in the opposite direction. Since the fiber raw material in the storage space can be scraped up little by little and fed to the next stage, if you want to continuously supply the fiber raw material to the next stage over a long period of time, the machine frame can be moved in one direction. While the machine frame is moving forward, the next fiber raw material is placed in the empty raw material storage space formed on the opposite side of the machine frame, and after the machine frame reaches the forward end, the machine frame is simply moved in the opposite direction. By advancing the fiber raw material to the next stage, the fiber raw material can be substantially continuously supplied to the next stage, and there is an effect that the fiber raw material can be efficiently supplied to the next stage over a long period of time.

Furthermore, even if the device is capable of continuously supplying the fiber raw material to the next stage over a long period of time as described above, the machine frame can only be fed in one direction as described above. The next fiber raw material can be stored in the empty raw material storage space formed on the opposite side of the machine frame in the opposite direction of travel while the machine frame is moving toward the opposite side of the machine frame. Since the mechanism is stopped, the next textile raw material can be temporarily fed into the raw material storage space at any time when the worker has free time, and the next textile raw material can be fed with less manpower. The supply can be carried out safely, the labor required for extracting the fiber raw material can be saved, and the safety of the work can be improved.
