Then, it is sent into the discharge pipe 63. By repeating this operation, the lump waste W is sequentially pushed into the discharge pipe 63.

[0005]

The fiber waste separated from the carrier air flow by the bag filter has a small specific gravity and is bulky, and the fibers have a property of being entangled with each other. Therefore, even if it is dropped and supplied to the hopper, the movement to the connecting pipe side is irregular. Further, the compressor 50 is commonly used for a large number of machine bases, and the number of bag filters is not limited to one, but two or more bag filters are usually mounted. For this reason, the hopper becomes large in size, and there are problems that the above-mentioned drawbacks are increased.

In view of these points, the present invention has an object to forcibly transfer the fiber waste supplied to the hopper to the connecting pipe side. Also, the supply of fiber waste from the hopper to the compression mechanism is
The supply is stopped during the operation of the compression mechanism. Therefore, fiber waste accumulates in the hopper during that time, and when the supply is restarted from the hopper, a large amount of fiber waste is temporarily supplied, which may cause trouble. A second aspect of the present invention aims to prevent a large amount of fiber waste from being supplied at the same time, and always transfer a fixed amount of fiber waste to the connecting pipe side.

[0007]

SUMMARY OF THE INVENTION To achieve the above object, a fiber waste compressor of the present invention comprises a hopper for accommodating the supplied fiber waste and the like, and a fiber waste compression mechanism attached to the lower portion of the hopper. In the fiber waste compressor, the hopper has a cylindrical shape with a bottom, a connecting pipe opening to the fiber waste compression mechanism is attached to one side of the bottom surface, a rotary blade is provided inside the hopper, and the rotary blade rotates to move the inside of the hopper. The supplied fiber scraps are scraped toward the connecting pipe side, and are pushed and supplied by a vertically moving supply mechanism.

According to a second aspect of the invention, a fiber waste supply amount control plate is attached to the hopper at a required distance from the bottom surface,
The rotary blade is provided between the regulation plate and the bottom surface so that the amount of fiber scraps attracted by the rotary blade is regulated by the regulation plate.

Further, according to a third aspect of the invention, the supply amount regulating plate can be adjusted up and down.

[0010]

[Operation] The fiber waste supplied to the hopper is scraped to the opening by the rotary blade and pushed into the connecting pipe by the supply mechanism. Further, even if the fiber scraps are accumulated in the hopper due to uneven distribution, the fiber scraps can be uniformly supplied.

[0011]

Embodiments FIGS. 1 to 4 show a first embodiment of the present invention. The fiber waste compressor 1 is provided with a hopper 2 having a bag filter F or a fiber waste input port 2b at its upper portion, and a compression mechanism 3 connected to the lower portion of the hopper. The hopper 2 has a cylindrical shape with a bottom, and a connecting pipe 4 that opens to the compression mechanism 3 on one side of the bottom surface.
And a rotary blade 5 for scraping the fiber waste accumulated at the bottom of the hopper 2 toward the connecting pipe 4 side. 6 is a supply mechanism for pushing the fiber waste W supplied into the hopper into the compression mechanism 3 through the connecting pipe 4, and 7 is an elevating cylinder for elevating the supply mechanism. Reference numeral 8 denotes a drive pulley attached to the drive shaft 40 at the center of the rotary vane 5, which is connected to an appropriate drive motor (not shown) by a belt 9. The compression mechanism 3 has the same structure as the above-described known structure, and the same parts are designated by the same reference numerals and the description thereof will be omitted. However, the connecting pipe 55 in FIG. 10 is the same as the opening connecting pipe 4 formed in the lower housing 56.

In the above structure, the rotary blade 5 rotates in association with the elevation of the supply mechanism 6. That is, as shown in the operation explanatory view of FIG. 3, the fiber waste W dropped and accumulated by the blades 5 is scraped to the connecting pipe 4 side and filled in the connecting pipe 4. Then, the rotating blades 5 scrape the fiber wastes W and connect the connecting pipes 4.
, The supply mechanism 6 is lowered, and the fiber waste W in the connecting pipe 4 is pushed into the lower housing 56. However, when the amount of fiber waste W supplied is large, the fiber waste W is stopped at a position passing through the connecting pipe 4 as indicated by a chain line 5a in the figure, and then the supply mechanism 6 is lowered to push down the fiber waste W. As described above, the positioning mechanism 41 is provided to determine the stop position of the rotary blade 5. The positioning mechanism 41 includes a rotation dog 42 attached to the lower portion of the drive shaft 40 and a limit switch 43 provided corresponding to the rotation dog 42.
2 operates the limit switch 43 to stop the drive motor and stop the rotary vane 5 at the above-mentioned proper position. As a result, collision with the rotary blades 5 can be avoided when the fiber waste is pushed in due to the elevation of the supply mechanism 6. Also, FIG.
When the number of dogs is set to two as shown in, the rotary vane 5 is stopped at the time when it rotates by 180 degrees and the fiber waste W is pushed down by the supply mechanism 6, but if the number of dogs is set to one, it is 3
If the number of blades is 60 degrees, the number of blades is 60, and the blades rotate 90 degrees. It is needless to say that the limit switch 43 can be an appropriate detector such as a photoelectric type.

Next, FIGS. 5 to 8 show a second embodiment.
The fiber waste compressor 20 of the present embodiment is similar to the above-described embodiment,
The hopper 2 is provided with a rotary blade 21 and a fiber waste supply amount regulating plate 22. This regulation plate 22 is used for the hopper 2
Is attached to the side wall 2a with a gap A from the bottom plate thereof, and the rotary blade 21 is disposed in the gap A and rotates. The other parts have the same structure as the previous example, and the same parts are designated by the same reference numerals and the description thereof is omitted.

In the above structure, the fiber waste W supplied into the hopper 2 is scraped by the rotary blades in the above-described manner and supplied to the connecting pipe 4 side. At this time, when the fiber waste is compressed by the compression mechanism 3, the supply of the fiber waste is stopped during that time, and the fiber waste is accumulated in the hopper. Therefore, when the supply is restarted, the amount of fiber waste supplied with the rotation of the rotary blade 21 is temporarily excessive. In addition, when the bag filter F or the amount of fiber waste supplied from the fiber waste inlet is temporarily excessive, the compression mechanism 3 may be hindered. In the present embodiment, this is prevented and the supply amount is constantly regulated. As shown in FIG. 7, excess fiber waste is prevented from moving by the regulation plate 22 and scraped off by the rotary blade 21. Only transfer. As a result, the amount supplied to the compression mechanism 3 side by the supply mechanism 6 is always constant, and it is possible to prevent a failure or the like due to excessive supply to the compression mechanism.

It is preferable to adjust the gap 8 formed in the lower portion of the regulation plate 22, that is, the scraping amount by the rotary blade. FIG. 8 shows an adjusting procedure of the regulation plate 22, in which a vertical groove 23 is formed on the side wall 2a of the hopper, and a mounting screw 24 of the regulation plate 22 is inserted into the vertical groove 23 and tightened so as to be vertically adjustable.

Next, FIGS. 9 to 10 show a third embodiment.
This embodiment shows a modified example of the supply amount regulating plate in the second embodiment, and the regulating plate 31 in this fiber waste compressor 30 has a gap B from the bottom plate of the hopper 2 and an inlet of the connecting pipe 4. Is attached to the side wall 2a in the above-described manner, and the rotary blade 32 is disposed in the gap B and rotates. The other structure is the same as that of the second embodiment, and the same parts are designated by the same reference numerals and the description thereof is omitted.

In the above-mentioned structure, the fiber waste W supplied into the hopper 2 is scraped in the above-mentioned manner and supplied to the connecting pipe 4 side. At this time, due to the fiber waste compressing operation in the compression mechanism 3, the supply of the fiber waste accumulated in the hopper 2 by the blades 32 is stopped, but the fiber waste introduced into the hopper is directly fed into the connecting pipe 4. You are prevented from migrating. Then, only the amount scraped by the rotary blade 32 is transferred. As a result, the amount of supply to the compression mechanism 3 is always constant, and it is possible to prevent a failure or the like due to excessive supply to the compression mechanism.

[0018]

As described above, according to the present invention, the fiber waste supplied to the inside of the hopper scrapes the fiber waste toward the compression mechanism by the rotation of the rotary blades and is pushed and supplied by the ascending and descending supply mechanism. Therefore, the specific gravity of the fiber waste is small, and there is a property of entangling, even if the transition to the connecting pipe side is unstable, because it is forcibly transferred by the rotary blade,
The supply of fiber waste to the compression mechanism side is stable, and moreover, it is possible to always supply a fixed amount, and it is possible to improve processing efficiency. . At this time, when a regulating plate for regulating the supply of the fiber waste is provided in the hopper, when the fiber waste is temporarily excessively supplied in the hopper, or the fiber waste is supplied for the compression operation of the fiber waste in the compression mechanism. When a large amount of fiber waste is accumulated in the hopper when the is temporarily stopped, it is possible to prevent excessive supply of fiber waste due to the start of rotation of the rotary blades.
