Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention adsorbs and removes dirt from dryer canvases used in paper manufacturing, press felt running manoeuvres, wires, other felt conveyors, running rolls, etc. The present invention relates to a cleaning device for cleaning.

[Conventional technology]

In general, foreign matter that adheres to the canvas, press felt, wire, etc. used to transport paper sheets used in paper machines, such as oils and fats including fibers and resins, and dirt such as hard substances such as sand, metal powder, and soil, If there is, it will be transferred to the paper sheet side and cause quality deterioration due to dirt, poor dehydration, paper breakage, and poor finish. Therefore, it is necessary to remove these foreign dirt by spraying cleaning water, brushing, or vibrating. Are known.

Conventionally, in this type of shower system, a pipe with multiple water supply nozzles attached close to the running canvas in the width direction of the canvas slides in the middle direction to wash the entire car. The amount of water is large, and it takes time to operate the push button and turn the pulp on and off each time the machine is operated.In addition, because the operation is performed intermittently, there are areas that are particularly dirty, sticky stains, dirt, and stickiness. In many cases, dirt cannot be removed, and the dirt in the middle of the canvas is not constant, and some areas may be contaminated with a lot of dirt, making it impossible to clean intensively. Attempts have also been made to move continuously, focus on cleaning localized dirt, increase the cleaning effect with a small amount of water, and save working time.

[Problem to be solved by the invention]

However, even in this conventional example, as the usage rate of waste paper increased, the amount of resinous and sticky stains increased, and it was difficult to remove the stains from the surface with Java washing water or brushing.

The present invention accurately eliminates these conventional drawbacks, transfers and removes sticky dirt that is difficult to remove with Java, etc., making it easier to clean the canvas, thereby improving the safety and quality control of paper manufacturing operations. The purpose of the present invention is to provide a cleaning device for paper-making canvas, etc., which enables improved performance, shortens working time and eliminates unnecessary operations, greatly improves reliability, and facilitates maintenance and security. It is.

[Means to solve the problem]

The present invention provides a canvas cleaning device equipped with a separator that moves in contact with the surface of a running canvas.
A cleaning device for a papermaking canvas or the like, characterized in that the separator is configured as a transfer cleaner that can physically remove and transfer adhesive stains and other stains adhering to the canvas surface.

[For production]

In this cleaning device, a separator that serves as a transfer cleaner moves and comes into contact with a canvas 2 on which a paper sheet 1 is placed and transported to the next process, and physically removes sticky stains and other stains that have adhered to the canvas surface. Compared to the conventional method of directly mechanically cleaning the canvas by removing dirt from the canvas by removing the adhesive and transferring it, the transfer cleaner can be cleaned mechanically more powerfully and is effective without damaging the canvas that comes in contact with the product. This makes it possible to remove stains and make quality control of paper sheets much easier and better.

〔Example〕

Regarding an example of applying the present invention to a dryer canvas,
To explain with reference to FIG. 1, a separator 3 that moves in contact with the surface of a canvas 2 on which a paper sheet 1 is placed and is transported to the next process is provided, and the separator 3 is attached to the surface of the canvas. The transfer cleaner is configured to physically detach and transfer sticky stains or other stains.

The separator 3 serving as the transfer cleaner is preferably a transfer cleaner having surface layers having different adhesion compatibility with the canvas 2 of sticky dirt. A running belt is used, which is hung around the belt, and the belt is made up of wires in the form of a net. For example, if the canvas is a wire, the transfer cleaner has a stronger adhesion force, so make the thickness, mesh roughness, and shape of the wire different from the canvas (thick wire or fine wire) to take advantage of the difference in the adhesion force of dirt. Alternatively, the contact surface may be a transfer cleaner made of a material with different adhesion compatibility, such as a transfer cleaner with better adhesion and stronger properties, or a belt or roller with an adhesive transfer layer.

Further, the separator may be a belt or a roller equipped with a pressure-sensitive tape having an adhesive layer, and may be disposed over the entire width or a part of the canvas, and the transfer surface may be cleaned or removed by the removal mechanism 5. Unlike directly mechanically cleaning the Canvas 2, the configuration in which transfer dirt is removed by passing the transfer cleaner through the transfer cleaner can be purified using a powerful mechanical cleaning method, which has a significant impact on the quality of the product. Can be used effectively without damaging the canvas 2. Further, the transfer cleaner can be used as a disposable type, for example, if it is a belt type, it can be continuously fed out and disposed of.

In addition, when the separator 3 is of a running heel type,
In addition to the contact-driven method, it is also possible to actively travel with a drive unit (not shown) and select the traveling direction or speed to improve the transfer effect.

In the figure, 12 is a roller and 13 is a dryer drum.

The example shown in FIG. 2 is of a type in which dirt on the surface of the canvas 2 is transferred while being brought close to or in contact with the canvas 2 stretched between guide rollers 12 and 12.

The transfer cleaner may be of a type that moves in the width direction or running direction of the canvas 2, and may include an electric circuit that controls the arrangement of the transfer cleaner by a motor drive operation based on a signal from a detector that detects dirt on the canvas 2, such as the one described above. The cleaning device may include a data processing section that performs arithmetic processing on data detected by the detector, and may be connected to each drive operation section.

In this case, the detector is configured to stop and restart the operation of the driving chino upon detection of dirt, and uses an area or line sensor consisting of a light emitting element and a light receiving element that constitute an image sensor to input fixed data and set it. It is preferable to use one that is connected to a computer unit of a data processing section that can be used.

〔Effect of the invention〕

The present invention provides a canvas cleaning device equipped with a separator that moves in contact with the surface of a traveling canvas.
Since the separator is configured as a transfer cleaner that can physically peel off and transfer adhesive stains or other stains adhering to the canvas surface, localized hard-to-remove stains or adhesive stains on the canvas can be removed. Automatic adhesion transfer and removal are possible, keeping the canvas in a clean state at all times, and there is no need for operators or monitors to be stationed at all times, allowing for accurate purification operation.
There is no need for water supply equipment costs, and operating costs can be greatly reduced, making it possible to improve the safety and quality control of paper manufacturing operations, shorten work time, eliminate unnecessary operations, greatly improve reliability, and improve maintenance and safety. In addition to being easy to use, it can be transported without having to replace the canvas or deteriorating the quality of the paper, and can also reduce costs.
