Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a concentrated dust collector in a textile machine.

BACKGROUND OF THE INVENTION In general, weaving machines and spinning machines use appropriate combinations of traveling cleaning devices, individual dust collectors, centralized dust collectors, etc. to remove generated cotton dust.

Problems to be Solved by the Invention Traveling cleaning devices can only clean the front and top surfaces of each machine, but cannot clean the inside or deep areas.
Separate dust collectors have no choice but to be used.

However, in loom factories, individual dust collectors are equipped with trolley transport passages or cranes for loom maintenance and beam replacement, and even in the case of spinning machines, running cleaning equipment and automatic doffing equipment Because of the equipment, etc., it is not possible to provide a dust collection box of sufficient size. Therefore, the inside of the dust collection box becomes full in a short period of time, and the inside of the dust collection box must be cleaned frequently.

Therefore, it is advantageous to install a centralized dust collector, but in this case, there are restrictions on the arrangement of the ducts, and the dust collection duct must be installed underground. but,
Installing underground dust collection ducts in existing factories requires high construction and equipment costs, and currently energy and labor savings are not progressing.

Means for Solving the Problems The present invention was proposed in order to solve the above-mentioned problems. An individual dust collector equipped with a connecting duct for centralized dust collection,
It is arranged along the upper part of each machine base, and has a normally closed connection port with a damper at a position corresponding to each machine base.
It is installed in a central dust collection duct connected to a central dust collection device and a traveling body that is arranged so that it can run along each machine platform, and stops each time it reaches the position of each machine platform. A centralized dust collecting device in a textile machine is configured by a connecting duct for concentrated dust collecting of an individual dust collecting device and a relay duct that connects a connection port of the duct for concentrated dust collecting and opens both dampers.

Function: The duct for concentrated dust collection can be placed above so as not to interfere with various types of moving objects. Each individual dust collector shall be provided with a connection duct for centralized dust collection. Then, a relay duct is provided on the traveling body, and it stops each time it reaches the position of each machine, and connects the connection duct for concentrated dust collection of the individual dust collector of the machine concerned to the connection port of the duct for concentrated dust collection. At the same time, by opening both dampers, the cotton dust such as fluff and fallen cotton collected in the individual dust collector of the machine is concentrated from the relay duct to the central dust collection duct. Let the dust collector collect the dust. The intensive dust collection time of each individual dust collector is set using a timer, etc., and when the intensive dust collection of one individual dust collector is completed, the traveling body is moved and the concentrated dust collection of the next individual dust collector is started. It is directed towards dust.
Incidentally, during the concentrated dust collection of each individual dust collector, the individual dust collection function is stopped.

The embodiment of the present invention has the above configuration, and its operation will be explained next.

Each loom A has a suction fan 9b of an individual dust collector B.
By continuous or intermittent operation of By the air jetted from the air jetting pipes 10, 10, the fluff received is collected in the suction cylinder 6, sucked through the slit 6a, and passed through the air intake duct 8 to the bag filter 9a in the upper half of the dust collection box 9. Collected on the inner surface. The suction fan 9a is activated at regular intervals by a timer or the like.
It is turned ON and OFF for intermittent operation, and when the amount of fluff adhering to the bag filter 9a reaches a certain level and the dust collection ability decreases, it is turned OFF to stop the suction fan 9b. As a result, the fluff adhering to the inner surface of the bag filter 9a peels off and falls into the lower cotton dust storage chamber 9d under its own weight. When the fly fluff peels off and falls, the dust collecting ability of the bag filter 9a is restored, and the bag filter 9a is turned on again to collect dust, and this process is repeated.

The concentrated dust collecting device F is operated continuously, and the traveling body D is caused to travel in order to collect dust intensively from one end of the looms A, which are arranged in large numbers. The running body D is
When the position of each loom A is reached, the sensor 15 stops the running. Along with this, the loom A
The individual dust collector B is connected to the centralized dust collector duct C via the relay duct E, and the cotton dust in the cotton dust collection chamber 9d of the individual dust collector B is collected in the centralized dust collector F. . The stopping time for concentrated dust collection of the traveling body D is as follows:
This is set using a timer or the like, and after the set time has elapsed, the machine starts running and heads to the next loom A. Then, during the stop time of the traveling body D, the suction fan 9b of the individual dust collector B is stopped to perform concentrated dust collection.

Although the above embodiment shows a case where a traveling type cleaning device is used as the traveling body D, other traveling bodies may be used, or a dedicated one may be used. Further, the individual dust collector B is not limited to the one illustrated in the drawings.

Furthermore, the device of the present invention can be applied not only to the loom A but also to spinning machines.

Effects of the Invention According to the present invention, a dust collection device with good dust collection efficiency can be individually installed at a dust-generating location of a textile machine without interfering with various running bodies. In addition, each individual dust collector is sequentially removed by the traveling body.
Since the dust is collected in a concentrated manner, each individual dust collector can be downsized and labor can be saved. Furthermore, since the duct for concentrated dust collection can be placed in the ceiling, etc., installation in existing factories is easy.
