Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dust collector for cleaning while traveling on a rail or the like.

[0002]

2. Description of the Related Art Conventionally, in a textile factory or the like, in order to prevent yarn breakage due to fly wool and to improve the working environment, weaving is performed along a linear rail provided above a weaving machine. 2. Description of the Related Art A dust collector that blows air onto a machine and sucks dust such as fly swabs on a floor to automatically perform cleaning is used.

[0003] In a conventional dust collector, air is blown out.
A housing equipped with two blow ducts and two suction ducts for sucking dust, a motor mounted in the housing, an impeller mounted on a shaft of the motor and driven to rotate, a filter connected to the two suction ducts, and the like are provided. Have been.

[0004] By the air flow generated by the rotation of the impeller, the air sucked from each suction duct is collected in one filter and passes from the inner surface to the outer surface of the filter, and the passed air passes through the space around the electric motor. Then, it flows into each blow duct and is blown out from each blow duct.

[0005] During that time, dust is sucked together with air and adheres to the inner surface of the filter, thereby collecting dust.

[0006]

However, in the above-mentioned conventional dust collecting apparatus, since only a single filter is provided, the air flow path becomes complicated and the air flow from the suction duct to the blow duct is increased. Turbulence occurs in the air flow, and a part like a pool without air flow occurs.
The air flow could not be uniform and smooth for each suction duct and each blow duct.

[0007] Therefore, there is a problem that the suction efficiency is reduced and that the collected dust is difficult to collect because the collected dust stays in a collecting place. In addition, since this type of dust collector travels on a rail provided near the ceiling, the height of the dust collector cannot be increased.
Therefore, the diameter of the filter cannot be increased,
The area of the filter could not be increased.

By the way, a collecting device having a collecting duct is installed at the end of the rail, and the collecting duct is inserted into the filter every time the dust collector makes one reciprocation on the rail. Dust is collected (JP-A-63-205188).

At this time, if the length of the rail is not too long (for example, about 30 m), one recovery per reciprocation is sufficient, but if the rail is long (for example, about 90 m). However, there is a problem in that the amount of fly waste accumulated in the filter during one reciprocation increases and the suction efficiency decreases.

In addition, depending on the conditions of use of the dust collecting apparatus regardless of the length of the rail, the degree of accumulation of fly waste in the filter and the degree of clogging of the filter differ depending on, for example, the type of fiber or the air conditioning method. , The same problem as described above may occur.

To solve this problem, the total area of the filter may be increased. However, if the size of the filter is simply increased, there is a problem that the height of the dust collector is increased.

In view of the above-mentioned problems, the present invention can provide a uniform and smooth air flow to the suction duct and each blow duct, improve the suction efficiency of the dust collector, and increase the total area of the filter. It is intended to increase the height of the dust collecting device and to prevent the height of the dust collecting device from increasing as much as possible.

[0013]

According to a first aspect of the present invention, there is provided an apparatus for blowing air to solve the above-mentioned problems.
One or a plurality of blow ducts and a housing to which a plurality of suction ducts for sucking dust are attached; a rotation drive shaft provided at a central portion of the housing for rotationally driving; an impeller for creating an air flow directed from the side to the blow side, are formed in positions on both sides sandwiching the previous SL rotary drive shaft within said housing, and a suction chamber communicating respectively with the respective suction duct, running while cleaning Do
A dust, wherein the positions on both sides sandwiching the previous SL rotary drive shaft in the housing over between the suction chamber mounted parallel to one another, 2 cylindrical, each of both end portions communicates with the respective suction chamber Having two filters , said housing
In the extension of the axis of each filter,
To collect and collect dust adhering to each filter.
An opening through which the collection duct can be inserted, and the opening
Open / close lid that is closed and opened by inserting the collection duct
Bets are configured provided.

[0014]

[0015]

The two filters are arranged parallel to each other across the suction chambers on both sides of the rotary drive shaft of a motor or the like in the housing, and both ends of each filter communicate with the respective suction chambers. doing. Therefore, each suction chamber communicates with the two filters at two positions, and a circulation path is formed by the two suction chambers and the two filters, so that the air flow is smooth.

Since the two filters are arranged in parallel, the area of the filter is almost doubled while keeping the height dimension.
