It is equipped with a drying unit that blows hot air onto the peripheral surface to dry it, and by controlling each of the units, the position of the adhesive roll is changed every predetermined time to automatically clean and dry the adhesive roll. It is characterized in that it comprises a control means for performing.

[0006]

The object to be removed comes into contact with one adhesive roll while being conveyed, and the dust adhering to the surface is adsorbed on the peripheral surface of the adhesive roll to be removed. In addition, while dust is removed by one adhesive roll, the other adhesive rolls are cleaned of dust adsorbed on their peripheral surfaces as described below, and the adhesive force is restored.

First, water or other liquid from the nozzle is added to the cleaning piece, so that the cleaning piece contains water or other liquid. Then, the cleaning piece is moved in the axial direction of the pressure-sensitive adhesive roll while being pressed against the peripheral surface of the pressure-sensitive adhesive roll rotated by the driving means, and at this time, dust on the peripheral surface of the pressure-sensitive adhesive roll is wiped off by the cleaning piece.

Warm air from the drying means is blown onto the peripheral surface of the adhesive roll which has been moistened by the cleaning piece to dry the adhesive roll to recover the adhesive strength. When the dust removal work by one adhesive roll reaches a predetermined time, the support brackets are rotated by a predetermined angle to replace the adhesive rolls with each other, and the adhesive rolls are cleaned to restore the adhesive force. Thus, the dust is removed, and the adhesive roll, which has been in the dust removing operation until then, has the dust adsorbed on its peripheral surface cleaned.

As described above, the plurality of adhesive rolls are used for the dust removing work by being replaced every predetermined time while being cleaned when they are removed from the dust removing work. The position of the adhesive roll, the cleaning of the adhesive roll and the drying of the adhesive roll are automatically performed in a predetermined cycle by the control unit controlling each unit.

Therefore, when the air cylinder 50 is extended, the pressing roll 46 is pressed by the adhesive roll 4, and when the air cylinder 50 is contracted, the pressing roll 46 is separated from the adhesive roll 4.

FIG. 6 shows an embodiment of the control means 52, which has limit switches 10, 27 and 28 connected to its input side and motors 9, 12 and 2 connected to its output side.
3, air cylinders 16, 30 and 50, solenoid valve 3
5, the blower fan 41 is connected. A sequencer 53 for sequence-controlling these control elements is built in the control means 52, and a timer 54 for adjusting the replacement cycle of the upper and lower adhesive rolls 4 is provided. 55 is a power switch, 56 is an air cylinder 50
Is a set switch for manually operating the.

Next, the operation of the above embodiment will be described. First, the power switch 55 is operated to turn on the power, and then the timer 54 is operated to adjust the replacement cycle of the upper and lower adhesive rolls 4. At this time, if a large amount of dust is attached to the object to be removed, the replacement cycle is set to be short, and if little dust is attached, the replacement cycle is set to be long. In addition, the set switch 56 is operated to operate the air cylinder 50.
Is operated to separate the pressing roll 46 from the upper adhesive roll 4, the dust removal target A is set in the gap between the pressing roll 46 and the upper adhesive roll 4, and the pressing roll 46 presses again. In this way, when the processing machine (for example, the textile printing machine) in the next step is operated, the dust-removed material A is pulled and conveyed in the direction of the arrow in FIG. 3, whereby the adhesive roll 4 and the press roll 46 are rotated. Then, the dust-removed object A rolls into contact with the adhesive roll 4 to start removing the dust adhering to the surface thereof. It should be noted that B and C shown in FIG. 3 are guide rolls provided at appropriate positions depending on the positional relationship with the processing machine in the next step.

While the dust removal work is performed by the upper adhesive roll 4 in this manner, at the same time, the lower adhesive roll 4 in which dust adheres due to the dust removal work so far and the adhesive force is reduced.
Is cleaned. That is, when the power is turned on, the solenoid valve 35 is first opened for a few seconds to a few dozen seconds based on the procedure set in the sequencer 53, and the cleaning piece 33 is sprayed with water from the nozzle 34, so that the cleaning piece 33 is not covered with water. It will be in the state of including. At the same time, the motor 12 is started, the air cylinder 16 is extended, and the rotational drive of the lower adhesive roll 4 is started.

Next, after the air cylinder 30 is extended and the cleaning piece 33 is pushed up, the motor 23 is activated and the cleaning piece 33 is pressed against the rotating adhesive roll 4 and moves rightward together with the moving table 24. Move to
The dust on the peripheral surface of the adhesive roll 4 is wiped off by the cleaning piece 33. The movable table 24 moves to the right end and the limit switch 2
When 8 is pressed, the rotation direction of the motor 23 is reversed, and the cleaning piece 33 cleans the adhesive roll 4 while moving the moving table 2
Move left with 4. Then, when it reaches the vicinity of the left end of the adhesive roll 4, dust adhering to the upper surface of the cleaning piece 33 is scraped off by the brush 38 rotating coaxially with the adhesive roll 4, and dropped onto the dust collecting tray 31.

When the movable table 24 returns to the left end and presses the limit switch 27 in this way, the motor 23 is stopped to stop the movable table 24, and the air cylinder 30 is contracted to lower the cleaning piece 33, and at the same time, the cleaning is performed. Drying of the peripheral surface of the adhesive roll 4 which has been moistened by cleaning with the piece 33 is started. That is, the blower fan 41 is activated, and the wind blown into the blower pipe 40 is heated by the steam pipe 44 through which steam has been previously passed, becomes hot air, and is ejected from the slit hole 45 to rotate the adhesive. The water is evaporated by being sprayed on the peripheral surface of the roll 4.

When this drying operation is completed, the blower fan 4
1 is stopped, the air cylinder 16 is contracted at the same time, the motor 12 is stopped, and the rotational drive of the adhesive roll 4 is stopped. At the above stage, the adhesive force of the lower adhesive roll 4 has been recovered, so the dust removal work by the upper adhesive roll 4 is only continued thereafter. Then, when the operation time reaches the replacement cycle of the upper and lower adhesive rolls 4 preset in the timer 54, first, the air cylinder 50 is contracted and the pressing roll 46 is separated from the upper adhesive roll 4. Be done. Next, the motor 9 is activated to rotate the support shaft 8 by 180 °, and when the limit switch 10 is pressed, the motor 9 stops. Now that the adhesive roll 4 has been replaced, the air cylinder 50 is extended and the pressure roll 4
6 is pressed against the adhesive roll 4, and the dust removal work is restarted.

Further, the timer 54 is reset to start counting the operation time of the adhesive roll 4 which is newly positioned on the upper side, and the solenoid valve 35 is opened to cause the cleaning piece 33 to collect water from the nozzle 34. The above procedure is repeated from the point where is added, and the cleaning of the newly lower adhesive roll 4 is started. In this way, it is possible to always remove dust with an adhesive force of a certain level or more while alternately switching the pair of adhesive rolls 4 and 4.

Since the time required to replace the adhesive roll 4 is as short as 1 to 2 seconds, when dust is sparsely attached to the dust-removing object A, the adhesive roll 4 is operated continuously.
It is unlikely that dust will be left behind even after replacing. Of course, the machine of the next process may be electrically interlocked so that the machine of the next process is temporarily stopped only during the replacement, and a device for accumulating dust A to some extent is also used between this automatic adhesive dust remover and the machine of the next process. Alternatively, continuous operation may be possible.

According to an example in which the woven cloth is dedusted by the above apparatus before entering the textile printing machine, the woven cloth conveying speed is 2 per minute.
When it is 5 m, the replacement cycle of the adhesive rolls 4 and 4 is appropriately about 4 minutes when the dust is most attached to the woven cloth and about 9 minutes when the dust is attached to the woven cloth.
The woven cloth was not stopped during the replacement, but the dust left behind did not cause any problems. Further, the dust accumulated on the dust collecting tray 31 can be removed by removing the screw 32.
1 is taken out of the machine and discarded, but it was enough to perform this work once a week.

It should be noted that it is desirable that the pressing roll 46 be separated from the adhesive roll 4 when the operation is stopped so that the adhesive roll 4 is not subjected to pressing strain. Also,
The pressing roll 46 is provided not at the position directly above the adhesive roll 4 as in the embodiment but at a position shifted in the conveying direction of the dust-removing object A to increase the contact angle of the dust-removing object A with the adhesive roll 4. You may let me. Further, depending on the property of the dust-free object A, the pressing roll 46 can be omitted.

In the above embodiment, the adhesive rolls 4 are paired (2
However, in this case, the replacement cycle of the adhesive roll 4 cannot be shortened to the time required for cleaning and drying one adhesive roll 4. Therefore, the dust removal object A
If you want to shorten the replacement cycle of the adhesive roll 4 because the transport speed of the adhesive roll is even faster or more dust adheres to the dust removal target A, use three adhesive rolls 4 to remove dust. When working, the other one is cleaned, the other one is dried, and so on. Of course, four or more adhesive rolls 4 may be sequentially replaced and used for dust removal work.

Needless to say, the automatic adhesive dust remover of the present invention is not limited to the above-mentioned embodiment, and a detergent or some kind of solvent may be added to the cleaning piece.

[0027]

EFFECTS OF THE INVENTION Since the present invention is constructed as described above, since it is automatically replaced with the adhesive roll cleaned at a predetermined cycle, the dust removing work can be always performed with an adhesive force of a certain level or more. There is no possibility that dust is left behind by the adhesive roll whose adhesive strength is lowered by neglecting the cleaning of the adhesive roll as in the past. In addition, since the operation after setting the dust removal object is completely automated, it does not take time and effort for cleaning as in the past, and it is not necessary to stop the operation for a long time for cleaning, thus improving work efficiency. Is greatly improved. Furthermore, since the adhesive rolls can be replaced in an extremely short time, it is only necessary to stop the transport of the dust-free objects in a moment, and the adhesive rolls can be replaced without stopping the transport depending on the transport speed and the degree of dust adhesion. However, there are many cases where there is no practical problem.
