21 and 34, geared motors 31 and 57, solenoid valves 59 and 66, etc. are connected.
2 and a microcomputer 73 in which a control procedure is stored.

Next, the operation of this embodiment will be described. The adhesive dust remover 1 is installed mainly on the upstream side of a processing machine for dust removing objects such as a printing machine. When the operation switch 71 is turned on prior to the operation of the processing machine, the air cylinder 19 is extended, the adhesive roll 12 is brought into contact with the surface of the dust removal target C at the position (a), and the air cylinder 21 is retracted. Since the adhesive roll 14 is moved to the predetermined adhesive roll peripheral surface cleaning position (C), when the processing machine is operated in this state, the dust removal target C is pulled by the processing machine and transported in the direction of the arrow in FIG. Thereby, the adhesive roll 12 is rotated to come into rolling contact with the dust removal target C, and the dust removal operation is started.

At the same time, the cleaning of the adhesive roll 14 to which the dust has adhered and the adhesive strength has been reduced by the dust removing operation is started. That is, first, the electromagnetic valve 59 is opened for several seconds to several tens of seconds, and the water from the nozzle 58 is applied to the cleaning piece 53, so that the cleaning piece 53 contains water. Next, the air cylinder 34 is extended and the drive wheel 36 is
4 and the geared motor 3
1 is started, and the rotational drive of the adhesive roll 14 is started. Then, the geared motor 57 is activated and the belt 5
6 moves toward the side plate 2,
The cleaning piece 53 containing water comes in contact with the peripheral surface of the rotating adhesive roll 14 and wipes off the attached dust. Mobile platform 5
2 moves to the end of the adhesive roll 14, the rotation direction of the geared motor 57 reverses, and the cleaning piece 53
4 is moved toward the side plate 3 together with the moving table 52 while performing the cleaning of 4. The dust collected on the upper surface of the cleaning piece 53 is brushed off when the cleaning piece 53 passes through the brush unit 16.

When the moving table 52 returns to the initial position, the geared motor 57 stops, and then the drying of the peripheral surface of the adhesive roll 14 moistened by the cleaning piece 53 is started. That is, the electromagnetic valve 66 is opened, steam is supplied to the steam pipe 65 and the blower fan 60 is started, and the air sent into the heating pipe 61 is heated by contact with the steam pipe 65 to become hot air. The water is evaporated from the slit holes 64 and sprayed on the rotating peripheral surface of the adhesive roll 14.

When the adhesive roll 14 dries and its adhesive strength is restored, the electromagnetic valve 66 is closed, the blower fan 60 is stopped, and the blowing of warm air is stopped, and at the same time, the air cylinder 34 is contracted. As a result, the drive wheel 36 is separated from the driven wheel 40, the motor 31 is stopped, and the rotational drive of the adhesive roll 14 is stopped. Since the cleaning and drying of the adhesive roll 14 are completed as described above, only dust removal by the adhesive roll 12 is continued thereafter. When the operation time of the adhesive roll 12 reaches the exchange cycle set in the adhesive roll exchange cycle setting timer 72, the exchange of the adhesive rolls 12 and 14 is performed. First, the air cylinder 21 is extended, the adhesive roll 14 is moved to the position (b), and the dust on the surface of the dust C to be removed by the adhesive roll 14 is started.
In addition, the adhesive roll replacement cycle setting timer 72 is reset, and the counting of the operation time by the adhesive roll 14 is started. Next, the air cylinder 19 is retracted, and the adhesive roll 12 is moved to a predetermined adhesive roll peripheral surface cleaning position (C). As in the case of the adhesive roll 14, the peripheral surface of the adhesive roll 12 is cleaned and dried. Done.

When the operation time of the adhesive roll 14 reaches the exchange cycle set in the adhesive roll exchange cycle setting timer 72, the exchange of the adhesive rolls 14 and 12 is performed. When the adhesive roll 12 extends and the adhesive roll 12 comes into contact with the surface of the dust object C, the portion of the dust object C located at the position (a) passes through at least the position (b), and then the air cylinder 21 contracts and sticks. The roll 14 is controlled so as to be separated from the surface of the dust C. This is because, for example, the adhesive roll 12 is
If the adhesive roll 14 is separated from the surface of the dust object C at the same time as it comes into contact with the surface, dust in the portion between the position (a) and the position (b) of the dust object C cannot be removed. The adhesive roll replacement cycle setting timer 72
Can be adjusted in accordance with the conveying speed of the dust C and the density of dust adhering to the dust C.

As described above, in the adhesive dust removing apparatus 1 of the present embodiment, when the adhesive rolls are replaced, no state occurs in which none of the adhesive rolls is in contact with the surface of the object to be removed. Even when the object is transported at a high speed or when the density of dust adhering to the surface of the object to be removed is extremely high, dust is not removed and left. In addition, since cleaning and drying of the peripheral surface of the adhesive roll are performed by moving the adhesive roll to a predetermined cleaning position of the peripheral surface of the adhesive roll, a set of a driving unit, a cleaning piece, and a drying unit may be provided. For example, there is an advantage that the structure of the apparatus is simplified and the manufacturing cost can be reduced as compared with a case where a driving unit, a cleaning piece, or the like is provided for each adhesive roll.

[0021]

Since the adhesive dust removing apparatus according to the present invention is configured as described above, at least one adhesive roll is brought into contact with the surface of the conveyed dust to remove dust, and at the same time, has a predetermined adhesion. At the roll peripheral surface cleaning position, the other adhesive roll is rotated and driven to clean the peripheral surface, and then dried to recover the adhesive strength of the adhesive roll. Then, when dust adheres to the peripheral surface of the adhesive roll that is in contact with the surface of the object to be removed, it can be replaced with an adhesive roll whose adhesive strength has been recovered by swinging the swing arm, The dust can always be removed with a certain level of adhesive strength.

When the adhesive roll is replaced, first, the swing arm that pivotally supports the adhesive roll whose adhesive strength has been restored is swung to bring the adhesive roll into contact with the surface of the dust-removing object. Next, the swing arm that pivotally supports the adhesive roll that has been in contact with the surface of the dust object is swung to separate the adhesive roll from the surface of the dust object. This allows the adhesive rolls to be replaced while maintaining the state in which at least one adhesive roll is in contact with the surface of the object to be removed. For example, when the transport speed of the object to be removed is high or when the dust adheres to the surface of the object to be removed. Even when the density is high, there is an effect that the dust can be removed from the surface of the object to be removed with high accuracy without removing the dust when the adhesive roll is replaced.

Further, since the cleaning and drying of the peripheral surface of the adhesive roll are performed by moving the adhesive roll to a predetermined cleaning position of the peripheral surface of the adhesive roll, one set of a driving means, a cleaning piece, a drying means and the like may be provided. For example, the adhesive roll 1
There is also an advantage that the structure of the device can be simplified and the manufacturing cost can be reduced as compared with a case where a driving means, a cleaning piece, etc. are provided for each book.
