Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a machine that generates a large amount of cotton wool, such as a textile machine in a textile factory, and a cleaning system suitable for cleaning the entire inside of the textile factory, and more particularly to a textile machine and an auxiliary device. A type of cleaning that removes dust such as cotton dust that has adhered to the factory by injecting high-pressure air, and also collects the dust, etc., swept to the aisles in the factory by the high-pressure air, unattended. Device and
The present invention relates to an unmanned traveling type automatic cleaning system including its accessory device.

[0002]

2. Description of the Related Art Textile machines such as weaving machines including looms and spinning machines such as roving machines and spinning machines, which are so-called textile machines, generate a large amount of dust such as cotton wool, and wind accumulated on various parts of the textile machines. If the dust such as cotton is not completely removed, dust such as flies accumulated on the textile machine will fall and mix into the product being processed. Product is produced without any product, quality deterioration due to machine stop due to a large amount of dust such as fly dust accumulated on moving parts such as rotating parts and sliding parts of textile machines, and production efficiency. A serious problem such as deterioration occurs.

For this reason, conventionally, a so-called air gun is used to suck dust such as cotton wool accumulated on various parts of a textile machine with a vacuum cleaner, sweep it with a brush or the like, and eject high-pressure compressed air. An artificial method has been carried out in which dust such as cotton dust and the like accumulated on each part of the textile machine is blown away to be used for cleaning.

On the other hand, a so-called traveling cleaner of a type in which dust such as cotton wool accumulated on various parts of the textile machine is blown off and scattered by wind pressure generated by a blower while traveling on rails installed in the upper space of the textile machine. However, not only will the cost of laying the rails be high and the construction will be large-scale, but it will be difficult to change the laying of the rails due to the change in the layout of the textile machinery after that.

Furthermore, since the traveling cleaner scatters dust such as cotton dust by air blowing from above, a large amount of dust such as cotton dust is deposited on the lower portion of the textile machine where wind pressure is difficult to reach. In recent years, in some devices, a flexible hose-shaped suction duct hanging on the floor of the aisle side of the textile machine has appeared to collect dust such as cotton dust. The suction range is limited to the extremely narrow range near the textile machine, and most of the dust such as cotton dust that has fallen to the lower part of the textile machine or the passage accumulates.
The mobile device fixed to the lower part of the textile machine and the problems of not only obstructing the passage of vehicles and workers, but also impairing the aesthetics were presented.

[0006]

SUMMARY OF THE INVENTION Therefore, the present invention has been made in view of the above problems, in which dust such as cotton wool is blown to a textile machine by blowing compressed air at relatively short intervals. It prevents the accumulation of dust and the dust such as cotton dust that has fallen to the bottom of the textile machine is swept into the passage by the jet air, preventing the quality of the textile products produced by the textile machine from deteriorating and stopping the textile machine. This is to prevent the production efficiency from being lowered, and at the same time, to collect dust such as dust swept on the aisle without using any artificial labor. It is an object of the present invention to provide an unmanned traveling type automatic cleaning system which can cope with a change in a passage due to a change in the layout of a textile machine.

[0007]

In order to achieve the above object, a guide member is to be a track of a so-called unmanned traveling cleaning device that travels unmanned in a factory passage in which a textile machine and its peripheral devices are arranged. Laying, the unmanned traveling cleaning device, while traveling in a predetermined passage by the guide of the guide member, automatically decelerates, stops, or by a sensor that detects a passerby or an obstacle appearing on the passage, or While self-determining the backward movement, compressed air is injected to the main movable parts of the textile machine and the lower part of the textile machine, and dust such as cotton wool is discharged into the passage.

On the other hand, the dust such as dust and the like carried out onto the passage by the injection of the compressed air can be stored in the dust storing portion provided on the front surface of the unmanned traveling cleaning device.

On the other hand, the route along which the unmanned traveling cleaning device travels is such that, due to the arrangement of the textile machines in the factory, the front and rear surfaces of the textile machines are alternately arranged to clean the entire factory efficiently and efficiently. Since it is indispensable to travel in a so-called zigzag manner, the direction of the compressed air injected from the unmanned traveling cleaning device is fixed to the unmanned traveling cleaning device, for example, on the right side. At the return route, dust such as dust and the like that is swept out will be swept to the passage that has already been cleaned, so in order to improve this and swept in a certain direction in the factory one by one, unmanned driving The direction of the compressed air injected from the cleaning device is opposite in the forward and backward directions, that is, if the forward direction is toward the advancing direction of the unmanned traveling cleaning device, and if it is injected from the right side surface, the unmanned traveling cleaning is performed in the returning route. How the device progresses Towards the injection nozzle so as to inject from the left side surface comprises means such as a rotating or switching.

Further, since the dust such as the cotton dust stored in the unmanned traveling cleaning device is a large amount, the dust such as the cotton dust collected when the unmanned vehicle is operated for a long time. Since the unmanned traveling cleaning device becomes large in size to store and load dust and it hinders traveling in narrow passages, dust such as cotton wool temporarily stored in the dust storage part of the unmanned traveling cleaning device is disturbed. Along with the transfer, a station for charging the traveling drive of the unmanned traveling cleaning device and a battery for injecting compressed air is installed in the factory, and a traveling path is set so as to periodically stop at the station. To be done.

[0011]

According to the present invention, the main passage of the textile machine and its peripheral equipment and its lower floor, and the textile machine can be utilized by utilizing the conventional passage without laying a dedicated track for running the unmanned traveling cleaning device. The passage between them, the floor of the entire factory, and
It can be effectively used for cleaning the walls of the factory and the ceiling of the factory.

As shown in the figure, the collision prevention sensors 9 and 10 are composed of a pair of right and left, or if only one traveling passage of the unmanned traveling cleaning device is provided at the center, only one is required. Needless to say, a collision prevention sensor is similarly provided above the rear bumper 8.

If an obstacle is found by the operation of the obstacle sensor, an alarm is given to a worker on the aisle to decelerate and further stop, and the presence or absence of movement of the obstacle and the moving speed are obstructed. Based on the information from the object sensor, if you activate the timer function and determine that it is not an obstacle that is moving, you can control the unmanned traveling cleaning device to move backward, such as the cotton swab that swept up when moving forward.

As described above, according to the present invention, the uncompressed vehicle guided by the guide member laid in the aisle of the factory in advance, the battery installed in the unmanned traveling cleaning device can be used for the traveling compressor as well as the compressor installed. Through the operation of the ultra-high pressure blower, the air blown out from the nozzle wipes out dust such as cotton wool accumulated on the textile machinery and auxiliary equipment, and the cotton underneath the equipment, and then sweeps it out to the passage in the factory. Installed in the unmanned traveling cleaning device so that dust such as dust in the factory is in a certain direction, it is done by switching the air blow nozzle to the left and right, and dust such as dust in the brush passage will be piled up in the next passage. The dust, such as cotton wool, stored in the brush device 5 is transferred to the brush device 5 after being stopped under a fixed dust collector as a station installed in a predetermined position. At the same time, by charging the battery mounted on the unmanned traveling cleaning device and preparing for cleaning after that, it is possible to continue to clean the textile machine and auxiliary equipment in the factory, and the aisle in a completely unmanned state. Since it adopts one that can move forward and backward, it can fully demonstrate its original function under any condition,
Further, since the running track is not installed above the textile machine, there is no significant defect such as dropping a worn metal piece from a rail or the like on the textile machine.
