Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is a cleaning product made of polyester paper, which is made by winding oil-impregnated polyester paper into a roll, the inside of which is uniformly impregnated or dipped (hereinafter referred to as dipping) with silicone oil by an adjustment mechanism. The present invention relates to a roller and its manufacturing method.

As shown in Figure 1, a commonly used dry type copying machine 1 has a thin selenium plate wrapped around a metal roller (hereinafter referred to as a drum) that conducts electricity well, and a high-voltage electrostatic electrode is attached to this. The drum 2 is uniformly charged by the ions of the corona discharge that is generated, and then toner powder 3 (colored material such as carbon powder is treated with resin and used to develop the electrostatic latent image on the drum) is used to develop the electrostatic latent image on the drum. When sprinkled with iron powder, etc.), the powder adheres only to the required letters and pictures.

Paper 4 is placed on top of this and a voltage is applied to transfer the powder on the drum 2 to the paper, which is then instantaneously heated and pressed between the Teflon coated roller 5 and silicone rubber roller 6, the powder is fixed to the paper and copied. is completed. (The dotted line indicates the flow of the paper 4.) However, when the toner 3 transferred to the paper is welded, the toner 3 is transferred to the Teflon roller 5,
As a result, the copy paper 7 (printed material) is contaminated.

In order to prevent such contamination, conventionally, a sponge-like silicone rubber roller 9 is placed in close contact with the Teflon roller 5 as a cleaner in the fixing paper discharge section 8.
It was used to remove the dirt, but the cleaning effect was not sufficient.

Therefore, service personnel from the store are dispatched based on the user's request and perform the cleaning work manually.

However, since the degree of contamination is proportional to the number of sheets of copy paper, service personnel are unable to patrol as expected, and users are forced to use the copy paper in a contaminated state.

In order to avoid these disadvantages, a tape cleaner made by simply applying silicone oil to the surface of a tape made of nylon or the like is known as a tape cleaner.

However, when the rollers of this tape are left in one direction for a certain period of time, the applied oil tends to shift or flow out. It is fine for cleaning, but in areas where the temperature reaches above room temperature, such as copying machines and VCRs, the tape itself stretches and the silicone oil itself moves laterally, making it impossible to fully demonstrate its cleaning function and making it unusable. However, the tape has drawbacks such as being expensive.

The technical problem of the present invention is to provide a cleaning function that absorbs contamination from the drum by contacting polyester paper uniformly doped with silicone oil in synchronization with the rotation of the Teflon coated roller, and Oil-impregnated polyester paper can be produced at a very low cost, and can be disposable. The point is to get used to it.

The structure of the present invention, that is, the technical means for solving the above technical problem is as follows.

In paper made of polyester fiber nonwoven fabric,
An oil-impregnated polyester paper in which silicone oil is doped in the amorphous porous portion of the nonwoven paper and a uniform silicone oil layer is formed on the surface thereof, and the oil-impregnated polyester paper is wound into a core roll. In the cleaning roller and the polyester paper made of polyester fiber nonwoven fabric with a large number of irregularly shaped pores, in the process of passing the polyester paper into the silicone oil tank, at least one
A silicone oil dipping step in which the paper is passed between sets or more of rollers equipped with sensors; a drying step in which the oil-impregnated polyester paper that has passed through the silicone oil dipping step is passed through a heat press or a tunnel-shaped drying chamber; and the drying step. A method of manufacturing a cleaning roller, characterized in that the cleaning roller is formed by winding it around a required core after it is flattened.

The above technical means works as follows.

Since silicone oil is evenly and evenly doped in the large mesh of polyester paper, a part of the silicone oil layer is transferred to the Teflon coating roller, and the polyester paper becomes a so-called non-woven fabric made of silicone-free oil. The toner adhering to the surface of the Teflon coated roller is adsorbed to the porous portion of the nonwoven fabric. Further, the silicone oil is transferred to the silicone rubber roller to impart releasability to the rubber roller.

Therefore, it becomes difficult for toner and the like to adhere to the rubber roller.

Embodiments of the technical means of the present invention will be described below based on the drawings. Since it is well known to make paper from polyester and wind it into a roll, a detailed explanation of the manufacturing method will be omitted.

Reference numeral 101 denotes a polyester paper 102 wound into a roll. The polyester paper 102 is rewound through a guide roller 103 and a feed roller 104, and is also fed into a silicone oil tank 10.
5.

The polyester paper 102 in the silicone oil tank 105 is doped with silicone oil 106 being forced into the gaps between the polyester paper fibers from both sides of the paper, and when led out of the tank in this state, an adjustment device, that is, the dipped polyester paper is Assuming that the thickness is, for example, 80 microns and the vertical error is ( )5 microns, the above value 1 is set to the luminescence spectroscopic optical sensor 107 installed at the required location, and the value measured by the sensor is between 75 microns and 85 microns. No signal is sent to the hydraulic control box 108 within the micron range, and if it exceeds this value, the signal is immediately sent to the hydraulic control box 108.
08, pressurized fluid corresponding to the signal is supplied to the hydraulic cylinder 109, and is attached to the rods 112, 113 of the hydraulic cylinder 109 (see FIG. 3) and connected to the adjusting rollers 115, 114 via connecting members 114, 114. The rollers 115 are moved closer to each other as shown by arrow a, and the rollers 115, 115 are narrowed to form a predetermined gap.

If the above value is insufficient, pressurized fluid is supplied to the hydraulic cylinder 109 via the optical sensor 107 and the hydraulic control box 108 as described above, and the rollers 115 and 115 are separated from each other as shown by arrow b. , 115 is widened to form a predetermined gap.

In order to accurately apply the signal transmitted from the optical sensor 107 to the detected area, the distance and the speed of the polyester paper 102 are replaced with a time difference, and this is input into an IC circuit, and an electrical signal is transmitted from the IC circuit to a transmission relay. Hydraulic cylinder 1 via
Most preferably, 09 is activated.

Hydraulic cylinders 110 and 111 operate in the same manner as hydraulic cylinder 109 described above.

The silicone oil 106 is evenly and uniformly applied by the adjusting rollers 115, 115 and simultaneously pushed into the mesh. (Refer to FIG. 4) Furthermore, the polyester paper 102 that has been led into the silicone oil tank 105 once again is lifted up while the silicone oil 106 in the silicone oil tank 105 is applied to both sides of the polyester paper 102, and then the guide rollers 116, 116 At the same time, excess silicone oil is scraped off, and at the same time, the shortage is made up in the mesh between the fibers, and an even and uniform silicone oil layer 117 and a silicone oil dipping layer 118 are formed on the entire outer peripheral surface. After becoming entangled with each fiber, the oil-impregnated polyester paper 119 of a predetermined thickness is passed through guide rollers 120, 120 and dried in a hot press (not shown), or dried in a tunnel shape as shown in the figure. It is dried in a machine 120 and formed as shown in FIG. 5, wound around a required core 122, and when it reaches a required length, is cut to complete the cleaning roller A.

Reference numeral 123 is a hydraulic control box 108
This is a pipe that connects the hydraulic cylinder 109 to the hydraulic cylinder 109.

Cleaning roller A made in this way
It is thin, heat resistant, has relatively high tensile strength, and has almost no fraying due to friction with rollers or expansion and contraction due to tension, so it is especially suitable for cleaning copying machines used above room temperature. Optimal.

Next, the usage state of the cleaning roller A of the present invention will be explained with reference to FIG.

Cleaning roller A set in a predetermined position
is rewound, and the oil-impregnated polyester paper 114 is passed through a Teflon coated roller 5 and a sponge roller 1.
23 and is wound around a separate winding core 124.

The shaft of the winding core 124 is directly or indirectly connected to a drum rotation motor.

Therefore, the oil-impregnated polyester paper 119 is smoothly wound around the winding core 124, which rotates simultaneously or synchronously with the rotation of the rotating drum 2.

When the oil-impregnated polyester paper 119 passes between the Teflon coated roller 5 and the sponge roller 123, a part of the silicone oil layer 117 dipped on the surface of the oil-impregnated polyester paper 119 is transferred to the surface of the Teflon coated roll 5. By this, the Teflon coated roll 5
For example, toner adhering to the surface of the polyester paper 119 is adsorbed to the polyester paper 119 (silicone oil doped on the polyester paper 119 is liquid, so it tends to adhere), and at the same time becomes easier to brush off downward from the Teflon coated roll 5. Then, the silicone oil on the outer peripheral surface of the Teflon coated roll 5 is transferred to the sliding silicone rubber roller.

As mentioned above, the cleaning roller A is made of silicone oil-impregnated polyester paper wound to a certain length, so once it passes between the Teflon coated roller and the sponge roller and is wound up on one side, it is disposed of and replaced with a new cleaning roller. exchange to. In this case, all you have to do is remove the core of the cleaning roller A, transfer it to the take-up core, and then wind the rewound oil-impregnated polyester paper around it.The feature is that it can be replaced very easily. has.

Since the cleaning roller of the present invention has silicone oil evenly doped between the fibers, the entanglement of these fibers is stabilized, and it is possible to prevent the silicone oil from shifting due to storage conditions.

In addition, there is no variation in cleaning ability no matter which part of the oil-impregnated polyester paper is picked up, and the releasable transfer to the mating roller can be smoothly performed over the outer peripheral surface of the roller.
