Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for removing heavy substances such as impurities or fiber lumps contained in fiber raw materials, and in particular, it can be used as a stand-alone fiber processing device and can also be connected to a spinning machine or a fiber processing device. The present invention relates to the configuration of a fiber separation device that separates the removed fibers discharged from these devices, separates the aforementioned heavy materials, particularly fiber lumps (hereinafter referred to as neps), and extracts only useful fibers.

Conventionally, dust removal devices have been used to remove impurities or neps from raw fibers, and some have been developed as stand-alone mechanical devices, or these devices have been added to mixed cotton machines, carding machines, and fine carding machines. It is arranged so that it can be removed from the fibers being processed.

That is, the former stand-alone dust removing device was designed to process a large amount of fiber raw material, and the device was too large to be installed alongside other machines.

Furthermore, the processing means were designed with processing capacity in mind, and there were still many unsatisfactory points in terms of separation of neps and the like.

On the other hand, the latter combined type was assembled into an attached mechanical device, and its processing action was to work together with the mechanical device to achieve its dust removal ability, so naturally it could not be used as a stand-alone device.

In the past, the processing capacity of these dust removal devices was mainly designed to match the processing capacity of the attached machine.

Typical of these are installed in carding machines with a high degree of opening, and are often installed especially around the take-in roller and cylinder.

Most of these separation means spread the fibers and scatter heavy materials such as neps using centrifugal force, and at the same time, create a suction airflow to collect useful fibers from the scattered fibers.
The processing speed of in-process fibers did not match the separation capacity, and satisfactory separation was not possible, resulting in poor dust removal effects.

The installation of these dust removal devices in a housing complicates the structure of the machine and requires a lot of effort to manage and maintain it, which has left few satisfied.

These facts can be understood from the fact that the above-mentioned dust removal device has been proposed for over 20 years, and although various improvements have been made, it has not yet been used as a practical device.

It is conceivable that the dust removal/separation device would actively take out the waste fibers from these mixed batting machines or carding machines, remove dust from them, and collect them using a separate separation device that is not attached to the fibers.

The present invention has been made in view of these problems, and as described above, the waste fibers discharged from the fiber processing machine are supplied directly or once stored and deposited, and are configured to be efficiently separated and dust-removed, and in particular, to separate and collect them. The aim is to provide a device that can perform this efficiently.

However, in such a device, a fiber suction duct is opened and connected directly to the opening and separation roller, and the suction force is used to adjust the collection suction airflow on the opening and separation section side, and then the fibers and the fibers on the opening and separation roller are adjusted. It is configured to suction and peel off the recovered effective fibers.

The present invention will be described in detail below based on the drawings, but the drawings show specific examples of the present invention, and the present invention is not limited to the illustrated examples, and the shapes may be changed in accordance with the spirit of the description described above or later. It can be implemented in the same manner by changing the assembly, changing the design, or changing the assembly.

Fig. 1 is a side view showing a specific example of the fiber separation device according to the present invention, in which raw material (waste fibers) is supplied in a stored and piled state, and the separated and recovered useful fibers are stored in an accumulation tank to form sheets. The following is an example of a device configured to be taken out in a shape.

In the figure, reference numeral 1 indicates a side frame, and the side frames 1 are arranged on both sides, and the front and rear sides are connected by cross rails to form a machine frame, and the separation device of the present invention is constructed by being assembled on these machine frames. .

2 is a raw material supply device, and the figure shows that these devices are composed of a lattice conveyor, but as mentioned above, when raw materials are continuously discharged from other fiber processing machines, this conveyor is used as a fiber waste accumulation device. It may be formed as a duct or connected to the cotton collection device of the return air duct, and can be configured in any shape.

These raw material supply devices 2 are also equipped with a feed roller device that sends out the deposited fibers in a substantially uniform thickness. It may also be of a type in which it is sent out using rollers.

Reference numeral 3 denotes a fiber opening and separation device constituting a main part of the present invention, and the separation device 3 is connected with a duct 8 for fiber separation and suction and a fiber separation and suction duct 7 of a stripping roller provided as necessary.

These ducts 8 and 1 are connected via a branch suction pipe 6 from a suction device 5 installed on a pedestal 4 provided on the frame 1, and are configured so that a suction airflow acts on each of them.

A fiber recovery tank 9 is connected to the discharge side of the suction device 5, and the recovery tank 9 can be freely selected, such as a one-hole type made of a perforated plate, a filter bag, or a cage roller. .

Depending on the need for shredding, the recovered fibers may be immediately returned to the fiber processing machine via a duct.

The figure shows an example of a deposition tank type, and a pair of feed rollers are provided at the bottom of the tank to take out the collected fibers in the form of a sheet.

10 indicates a square provided on the side frame 1 so as to be openable and closable.

As described above, the main part of the present invention relates to the configuration of the fiber opening and separation device 3, and these will be described in detail below.

FIG. 2 is an enlarged side view of the opening and separating device, with the side frame 1 cut away, and FIG. 3 is a central sectional view showing its structure and function.

In these figures, the opening and separating device 3 mainly consists of a opening and separating roller 12, and the separating roller 12 has a toothed wire wound around its surface like a take-in roller and a cylinder provided in a carding machine. Alternatively, a tooth member is implanted or fitted, like a cylinder of a fine carding machine, to form a tooth portion on the entire surface.

These teeth have an appropriate tooth shape and function for opening the fibers and hooking and transporting the fibers depending on the fiber raw material.

Depending on the raw material, it may be a pin cylinder.
In this case, it is particularly recommended to use a cylinder in which the pin protrudes at the fiber opening section and retracts at the fiber peeling section.

However, such a separation roller 12 is attached to the side frame 1.
, 1 fixedly provided on the side stand 11. IN (one of which is not shown) is freely supported and driven by a drive device (not shown).

A supply table 17 and a feed roller 18 attached to the raw material supply device 2 described above are disposed on the front side of the approximately central part of the separation roller 12, and a cover plate 22 is attached to the separation roller 12 via a separation plate 20 on the lower side. 12 from the outside air.

The separating plate 20 is fixed to side plates 21 and 21 (one of which is not shown) which are provided substantially concentrically and rotatably on both sides of the separating roller 12, with a slight gap 26 between the separating plate 20 and the circumferential surface of the separating roller 12. Configure it so that it can be formed and moved around the surface.

The folded cover plates 22 can also be provided on these side plates 21.

A free space is formed between the supply table 17 and the separation plate 20 on the circumferential surface of the separation roller 12.

On the other hand, the above-mentioned suction duct 8 opens on the opposite side of the separation roller 12 from the supply table 17, corresponding to the width of the roller 12, and faces the separation roller 12 in a tangential direction as shown in FIG.

The tip of the bottom side 8 of the duct 8 forms an opening/closing adjustment plate 24 to form an air introduction passage 25 corresponding to the cover plate 22, and the opening degree of this air introduction passage 25 is adjusted by an adjustment lever 27. Ru.

Further, a separation piece 23 is formed at the tip of the suction duct 8 above the pair of separation rollers to form a slight gap with the separation roller 12, and the gap is also adjustable.

14 is a separation roller cover, and 19 is a clearer roller.

The lower portions of these separation rollers 12 are left empty to form a separation chamber 30, and a front wall 28 and a rear wall 29 are provided to prevent the inflow of outside air.

Note that, if necessary, a void may be actively formed at the top of the front wall 28 to allow outside air to flow in.

The fiber separation device of the present invention configured as described above has a separation roller 1.
2 rotates at high speed in the direction of arrow A, and the fibers gripped by the supply table 17 and the feed roller 18 are fed to the separation roller 12 side by the rotation of the feed roller 18.

The supplied fiber group is subjected to a fiber opening action by the separation roller 12, and heavy objects such as the aforementioned neps are scattered and fallen in the centrifugal direction as shown by line E, and are separated from other objects and removed.

Also, due to this opening action, some fibers are separated from the separation roller 12.
Some of the fibers are held by the teeth of the fibers, and some of the fibers are separated from the free space while floating in the separation chamber 30.

However, in the apparatus of the present invention, a suction airflow as shown by a curve F or a straight line J is actively formed in this free space, and the floating and separated fibers are collected by the suction airflows F and J.

However, such suction airflows F and J can be formed only by the accompanying airflow caused by the high-speed rotation of the separation roller 12, but they are extremely small and are only in the vicinity of the gap 26.

Therefore, it is necessary to supplement the suction flows shown by F and J with other suction forces.

Therefore, in the present invention, the fiber separating action of the separating roller and the formation of the suction airflows F and J described above are performed simultaneously by the suction of the suction duct 8.

Therefore, the feed material is subjected to a fiber opening action by the separation roller 12, and heavy materials such as neps contaminants contained therein are deposited on the bottom surface of the separation chamber 30 as shown at 31, and the material is effectively (usable). The fibers are transported by separation rollers 12, and the separated floating fibers are collected by suction airflow.

The separation roller surface that has reached the opening of the suction duct 8 separates the fibers held by the suction airflow of the suction duct 8 as shown by G into the suction duct 8.

The loose and floating fibers are also collected by the suction duct 8 via the cover plate 22 and the separation roller 12, and collected in the collection tank 9 as described above.

However, the separation roller 12 may not completely separate the spread fibers depending on its tooth profile or the type of raw material fiber.

Therefore, as shown in the figure, a stripping roller 13 is provided, that is, the stripping roller 13 is formed by implanting wires on its surface or attaching a member having these wires implanted thereon, and is formed almost perpendicularly to the top surface of the separating roller 12. and actively rotate it as shown by arrow B to separate the separation piece 2.
In step 3, the fibers that were not completely separated and adhered to the separation roller are completely peeled off.

The stripping roller 13 is almost surrounded by a top cover 15 and a bank cover 16, and a suction duct 7 is provided in a part thereof.

Further, as shown in FIG. 1, a suction airflow is applied to the suction duct 7 from the suction device 5 via the branch suction pipe 6 to peel off the fibers adhering to the stripping roller 13.

H indicates this peeled fiber.

That is, as shown in FIG. 3, the raw fibers are spread apart at the separation port 12 to remove heavy materials, and only the effective fibers are separated by the suction airflow of the suction duct 8, and the collected airflow F, J is formed and floating fibers are also suctioned at the same time.

The fibers adhering to the shredded stripping roller 13 are peeled off by the suction air stream C of the suction duct 7, and these peeled fibers are fed to the collection tank 9 or other suitable device as described above.

If necessary, the separation piece 23 formed at the opening of the suction duct 8 may be replaced with a small-diameter stripping roller so that the fibers adhering to the separation roller 12 are actively brushed off and the fibers are sucked into the suction duct 8. In this case, the stripping roller 13 can be removed.

As described above, the fiber separation device of the present invention is configured as an independent separation device, and its separation and collection means uses a group of opening and separating rollers and a suction duct formed through the roller group to separate the fibers and collect floating fibers. Since it is configured to collect by forming an air current, it is possible to reliably remove heavy objects with a simple configuration, and moreover, it is possible to reliably collect useful fibers.

These machines can be easily connected to fiber processing equipment, and wastes removed from these machines, such as cotton drops in carding machines, armored cotton, or cotton drops under the beater of mixing machines, etc. It is possible to obtain a cotton belt free of impurities by processing the above, and its use is extremely effective.
