Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a concentrated dust collection device for a textile machine.

In order to remove the generated cotton dust, a traveling type cleaning device, an individual dust collecting device, a concentrated dust collecting device, etc. are used in appropriate combinations in dish rice, looms, and spinning machines.

While the issue is being resolved, B City's mobile cleaning equipment can only clean the front and top surfaces of each machine, but cannot clean the interior or deep areas. , an individual dust collector must be used.

However, individual dust collectors are used in loom factories to maintain looms.
There is a carriage passage or crane for beam exchange, and even in the case of spinning machines, there is a moving type leaning device, automatic doffing device, etc., so a dust collection box of sufficient size is required. cannot be set up. 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 collection system, but in this case, there are restrictions on duct placement, and it is necessary to install an underground dust collection duct. The current situation is that the construction and equipment costs are high to install such systems, and that energy and labor savings have not progressed yet.

The present invention for reducing the r An individual dust collector equipped with a connecting duct for centralized dust collection, and a normally closed connection port with a damper installed along the top of each machine stand at a position corresponding to each machine stand. It is installed in a central dust collection duct connected to the device and a traveling body that is movable along each machine, stopping every time it reaches the position of each machine and collecting the dust individually for that machine. A concentrated dust collection device in a textile machine is constructed by a connection duct for concentrated dust collection of the dust device and a relay duct that connects the connection port of the duct for concentrated dust collection and opens both dampers.

The concentrated dust collection duct can be placed above so as not to get in the way of various running bodies. 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 fluff, fallen cotton, and other cotton dust collected in the individual dust collector of the machine will be collected in a concentrated manner from the relay duct to the central dust collection duct. Let the dust device 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.
