JP3725201B2 - Fluff removing device in airflow type fabric processing apparatus - Google Patents

Description

[0001]
[Industrial application fields]
TECHNICAL FIELD The present invention relates to a fluff removing device in an airflow type processing device for a fabric that performs a process such as a texture processing by circulating and rotating a rope-like fiber product in an endless manner.
[0002]
[Prior art]
Conventionally, removal of fluff in an airflow type processing apparatus is performed by providing a filter in the middle of a circulation pipe, causing the circulating gas to pass through the filter medium, thereby attaching the fluff to the filter medium, and removing the filter medium during or after the processing step and attaching it to the filter medium As a filter medium, a cylindrical perforated plate or a wire mesh was used.
[0003]
[Problems to be solved by the invention]
In a conventional airflow type processing apparatus, fluff is generated and circulated in the circulating gas by circulating and rotating the cloth by airflow jetting, and the fluff floats in the circulating gas and circulates in the apparatus. There was a negative effect on the operation of the fabric due to the clogging of the gap and the lowering of the injection force. Further, the fluff was reattached to the treated fabric staying in the staying tank, thereby causing contamination of the fabric. Therefore, it is necessary to remove the fluff floating and circulating in the air current as much as possible. However, in the conventional filter system, it is necessary to check the filter medium after each treatment and remove the attached fluff. Also, when processing a fabric with a lot of fluff, the filter is clogged with a lot of fluff and becomes the resistance of the circulating gas. There was a problem that the production efficiency was lowered because it was necessary to replace the filter in order to cancel the clogging of the filter by interrupting the processing.
[0004]
[Means for Solving the Problems]
In order to solve the above-mentioned problem, in an apparatus for circulating and processing fiber products joined endlessly by a jet stream,
An airflow type fabric device characterized in that a separator using centrifugal force is installed in the middle of the airflow circulation path and a discharge port for discharging fluff separated from the airflow is provided at the lower end of the separator. Equipment for removing fuzz.
[0005]
[Action]
In the present invention, the fluff that is generated in the airflow jetting unit or the like and floats and circulates in the gas is separated by a separator using a centrifugal force provided in the middle of the circulation path, and provided at the lower part of the separator. Since the fluff separated from the discharge port is continuously and naturally discharged from the separator so as to be accumulated in the fluff reservoir portion provided in communication with the lower portion thereof or discharged into the fluff storage bag. There is no harmful effect of fluff accumulation like a filter provided in the middle of the circulation path. Therefore, a stable product can be produced without the generated fluff recirculating in the apparatus.

【Example】
Embodiments will be described with reference to the drawings.
FIG. 1 shows an embodiment of the present invention, where 1 is an endlessly treated fabric, 2 is a staying tank, and the exit of the staying tank is connected to a reel box 4 provided thereabove via an ascending path 3. Yes.
[0007]
The reel box 4 has a pull-up reel 5, which is rotated by a drive motor (not shown) to move the fabric 1 moving in a meandering state from the stay tank 2 to the jet nozzle 6. The injection nozzle 6 has a slit portion 6 a serving as a gas passage. Gas is injected from the slit portion and comes into contact with the fabric 1. The fabric 1 is pumped together with the gas into the transfer pipe 7 and is released from the transfer pipe 7 at the upper part of the inclined inlet portion 9 of the staying tank and slides down along the inclined inlet 9 while moving in a meandering state. Sent to the lifting section.
[0008]
4a is an operation lid for inserting and removing the fabric 1. The inside of the apparatus is laid endlessly and then sealed and pressurized to a predetermined pressure.
The gas circulation path passes through the fluff separator 11 connected to the upper gas phase portion of the retention tank 2 via the suction pipe 10, passes through the pipe by the blower 14, passes through the discharge pipe 15, and passes through the gas in the heat exchanger 16. The temperature is adjusted, and it is sent to the injection nozzle 6 through the pipe 17 via the flow regulating valve 27, and is injected into the transfer pipe 7 from the slit portion 6 a and returns to the retention tank 2 from the inclined inlet portion 9 of the retention tank. Yes.
[0009]
Reference numeral 12 denotes a fluff reservoir, which is connected to a fluff storage bag 19 through a discharge valve 18 from the bottom of the fluff reservoir 20 via a discharge valve 18. Reference numeral 21 denotes a container for holding the fluff storage bag.
8 is a fluff generated by contact with the gas injected from the injection slit 6a, contact with each tank wall surface during high-speed circulation rotation, contact between fabrics, etc. Is circulating. A fluff floating in the air current is separated using a separator provided with a centrifugal force provided in the middle of the circulation path, and the separated fluff is separated from a discharge port provided at the lower end of the separator 11 to a fluff reservoir 12. Can be stored. By intermittently opening the discharge valve 18, it is discharged into the storage bag 19 using internal pressure.
[0010]
FIG. 4 shows a conventional airflow processing apparatus.
Reference numeral 22 denotes a filter box, in which a filter is housed and connected to a gas phase portion on the upper side of the retention tank 2 by a suction pipe 24. Reference numeral 25 denotes a pipe connected to the blower 14 and is connected so that the airflow passes through the filter 23.
[0011]
A discharge pipe 15 connects the blower 14 and the heat exchanger 16 and is a circulation path in which the heat exchanger 16 and the injection unit 6 are connected by the pipe 17.
FIG. 2 shows a circulation path for performing fluff separation using the centrifugal force of the present invention in an atmospheric pressure type airflow processing machine, and the fluff 8 stored in the fluff reservoir 12 at the lower part of the fluff separator 11. The discharge valve 18 is intermittently opened and discharged into the fluff storage bag 19.
[0012]
FIG. 3 shows a structural diagram in which a fluff storage bag 19 is provided directly on the separator and is always discharged.
[0013]
【The invention's effect】
The airflow type processing apparatus of the present invention has the above-described configuration, and fluff generated from the fabric is separated by a separator using a centrifugal force arranged in a vertical shape and is naturally discharged continuously from the discharge port at the lower end. Is done. Therefore, if the fluff reservoir 12 or the storage bag 19 is disposed at the lower part of the discharge port, the separator can be disposed of satisfactorily. Since the separated fluff is immediately eliminated, the separation operation is always performed effectively, and stable operation and efficiency are achieved. Production can be expected.
