[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for removing abrasive powder from a polished rubber roll, which is mainly provided in a facsimile.

[0002]

2. Description of the Related Art A rubber roll for a facsimile cannot be used unless it has been polished in advance. However, to completely remove the abrasive powder attached to the roll during polishing,
It was not easy, and the removal of the polishing powder varied depending on the operator. There is also a method of immersing a rubber roll in a water tank containing alcohol, but this alone could not remove the polishing powder.

[0003]

[Problems to be solved by the invention] The polishing powder that could not be removed in the water tank was wiped off with a cotton cloth or blown off with compressed air. The polishing powder was stained, and the removal of the polishing powder was not performed efficiently. In view of this point, an object of the present invention is to provide a method capable of reliably and efficiently removing abrasive powder from a rubber roll and preventing scattering of the abrasive powder.

[0004]

[Means for Solving the Problems] The grinding of the rubber roll of the present invention is performed.
The grinding powder removing device is a carry-in device that receives and conveys the polished rubber roll on the feed roll in the longitudinal direction, and the rubber roll
Cleaning device and compressed air
Equipped with a dehydrator that sprays and blows off washing water,
The roll should be perpendicular to the feed roll along its circumferential direction.
Has a groove for receiving the rubber roll in the
The cleaning device
And in the dehydrator before washing and dehydrating before the feed roll.
A press roll is provided to press the rubber roll into the groove.
I have. The press roll has a groove along its circumferential direction.
The rubber roll is pressed by this groove. The cleaning device
Sprays washing water, arranged on all sides of the rubber roll
A washing nozzle is provided, and the dewatering device is provided on all sides of a rubber roll.
Air that blows off water droplets with compressed air
It has a blow nozzle.

[0005] Hereinafter description will explain the present invention in one embodiment, shown in FIGS. Figure 1 is intended to illustrate a device used to remove the abrasive powder from the rubber roll after polishing,
It is sectional drawing explaining the outline. A drive motor 1 comprising a carry-in device, a washing device, a dehydration device, and a take-out device.

A large number of feed rolls 3 are provided.
The feed roll 3 is rotated by the belt 2
Are sequentially transported on the groove. The washing device and the dehydrating device are located in the same closed chamber, and the washing device is a water tank 5 as a washing water circulating device, a pump 6 for pumping washing water , a tank 7, and water.
Pump 8 for supplying under pressure and nozzle 9 for injecting water
Comprising a, the dewatering device comprises air compressor 10, the blow nozzle 11. Fig. 2 shows the main part of the cleaning device .
FIG . 3 is a front view showing a main part of the dehydrating apparatus .

This embodiment has an outer diameter of 10 mm and a length of 310 mm.
in mm of the core, the outer diameter of 20 mm, a rubber roll obtained by adhering a silicone rubber of a length 220 mm, is to remove the polishing powder attached when polished. Abrasive powder adhesion
Feed roll 3 for transporting the cured silicone rubber roll 12
Along its circumferential direction, as seen in FIGS.
The silicone rubber in the direction perpendicular to the feed roll 3
A groove 16 for receiving the roll 12;
Roll 12 spans grooves 16 of several feed rolls 3
And are sequentially conveyed by the rotation of the feed roll 3. The polished silicone rubber roll 12 is placed on the groove 16 of the rotating feed roll 3 by hand or by natural fall.
Then, the feed roll 3 carries it into the cleaning device. The cleaning device includes a silicone rubber roll 12 as shown in FIG.
Pressurized water is sprayed onto the silicone rubber roll 12 from the washing nozzles 9 arranged in four directions around the surface of the silicone rubber to wash away the abrasive powder adhering to the silicone rubber roll 12. In this case ,
To avoid the influence of the pressurized medium pressure injected, pressing the front and rear of the silicone rubber roll 12 at the pressing roll 13. Presser foot low
The roll 13 is provided on the feed roll 3 along this circumferential direction.
A groove 17 is provided at a position opposed to the groove 16 formed.
The cone rubber roll 12 is tightly held by the grooves 16 and 17.
It is pinched with a kari.

[0007] Silicone rubber roll 12 after cleaning, are sent to the next dewatering device because water droplets adhered, air blow nozzle 11 compressed air from the air compressor 10
It is injected from, as shown in FIG. 3, blow off water droplets adhering from four directions in the silicone rubber roll 12. At this time, the roll is pressed by the press roll 14 so that the roll is not skipped. The presser roll 14 has the same groove as the presser roll 13.
17 are provided. It is effective to use a compressed air pressure of 4 kg / cm ² or more. After these steps are completed, the silicone rubber roll 12 is carried out of the cleaning device and stopped by the stopper 4. To explain the flow of washing water,
The water after washing away the abrasive powder is stored in a water storage tank 5 and sent by a pump 6. In this case , the water is purified through the filter 15, stored in the tank 7, and further sent to the washing nozzle 9 by the pump 8. Cleaning water is repeatedly purified and circulated
And always supplied in a clean state.

[0008]

[Effect of the invention] According to the invention, the rubber roll is a feed roll.
Is transported in the longitudinal direction on the groove of
Cleaning by pressurized water injection and pressure
Dehydration by blowing compressed air becomes possible, and the polishing powder of the rubber roll can be surely and evenly removed without unevenness, so that a high-quality rubber roll can be provided for a facsimile machine. Further, since the scattering of the polishing powder can be prevented in the polishing powder removing operation, environmental pollution is eliminated. In addition, the water can be reused many times through the filter, which is economical.
