Description

[Detailed Description of the Invention] <Technical Field> This invention relates to an apparatus for removing dust from the surface of cloth sent to a textile printing process.

<Prior art> Conventionally, if dust adheres to the fabric surface during the printing process, the dust will be printed along with it, and the dust will be removed after printing and the area will turn white, resulting in defective products, or the printed pattern will be damaged. Since dust may adhere to the cloth and cause clogging, etc., resulting in defective products, the cloth surface was removed before the printing process.

As shown in FIG. 1, the dust removal method involves rotating a roller 3 coated with adhesive on the outer periphery of the cloth 1 while bringing it into contact with the surface of the cloth 1 to be sent to the printing process.
The dust 2 on the surface can be removed by adhering it to a roller 3, or as shown in FIG. The dust 2 was removed by suction.

However, in the former method of using the roller 3 coated with adhesive, if too much dust 2 adheres to the roller 3, it becomes impossible to remove the dust 2 from the surface of the cloth 1 that is sent afterwards. In addition, the latter method using a dust collector requires a large suction force as it is necessary to suction the entire width of the cloth 1.
There was a problem with high power consumption.

<Purpose of the invention> This invention involves sliding a dust-removing cloth on the surface of the cloth that is sent to the textile printing process, allowing the dust on the surface of the cloth to adhere to the dust-removing cloth and removing it, and removing the dust that has adhered to the dust-removing cloth from an air nozzle. To provide a cloth surface dust removal device which can blow and collect dust by using air flow, and can make a dust removal cloth recyclable, which requires less effort and consumes less power.

<Structure of the invention> The gist of this invention is a device that removes dust from the surface of the cloth sent to the textile printing process using a dust-removing cloth with diagonal bristles. The cloth is brought into sliding contact in the opposite direction to the cloth moving direction so as to make the pile stand on end, and an air nozzle is provided at the bending part of the dust cloth to send an air flow in the diagonal direction of the pile on the surface of the dust cloth. The cloth surface dust removal device is characterized in that a dust storage cover is disposed near the tip of the air nozzle and opens so as to cover the entire width of the dust removal cloth in the width direction and face the air nozzle.

<Example> Fig. 3 is a schematic sectional view of a fabric surface dust removal device showing an embodiment of this invention, Fig. 4 is an explanatory view showing a state in which dust is blown off in the same embodiment, and Fig. 5 is a diagram showing a state in which dust is blown away in the same embodiment. A view taken in the direction of arrow A and FIG. 6 are explanatory diagrams showing a state in which the resistance of the dust cloth to the cloth is adjusted in the same embodiment, and FIG. 7 is a plan view showing another embodiment.

A cloth surface dust removal device 15 shown in FIG. 3 is used to transfer cloth 11 from a cloth roll to a printing process in order to remove dust 12 adhering to the cloth 11 while being sent from the cloth roll to an autoscreen machine or the like in the printing process. It is arranged on the belt roller 13 at the end of the conveying belt conveyor 14.

This cloth surface dust removal device 15 has oblique bristles on the surface (oblique angle of about 30 degrees, bristles length 1.5
~5 mm), the endless dust-removing cloth 16, which is slightly wider than the width of the cloth 11 being conveyed,
They are slid against each other in the opposite direction to the direction of movement of step 1 and in such a way that the bristles stand on end. In addition, this dust removal cloth 1
6 can be exemplified by the product name Etiquette Brush (manufactured by Nippon Seal Manufacturing Co., Ltd.).

The dust-removing cloth 16 is driven in circulation at a speed slightly slower than the moving speed of the cloth 11 by a drive roller 17, a press roller 18, a subtension roller 19, and a tension roller 20, which are each held by a frame (not shown). The dust cloth 16 that was in contact with the cloth 11 is peeled off from the circumferential surface of the belt roller 13 by a contact surface adjustment bar 21 fixed to a support plate 22 held on a frame (not shown). . In addition, the subtension roller 1 is installed so that the resistance at the contact surface between the cloth 11 and the dust removal cloth 16 can be adjusted as described later.
9 and the contact surface adjustment bar 21 are respectively arranged so as to be movable and adjustable in the horizontal direction with respect to a frame and a support plate 22 (not shown), and the tension roller 20 is arranged so as to be movable and adjustable in the vertical direction with respect to the frame (not shown). has been done.

An air nozzle 23 is installed above the dust-catching cloth 16 which is bent on the circumferential surface of the drive roller 17 by the pressing roller 18 to send an air flow in the diagonal direction of the pile on the surface of the dust-catching cloth 16. An opening 24 that covers the entire width of the dust removal cloth 16 is disposed near the center in the width direction of the air nozzle 16 and is held by a frame (not shown) facing the outer periphery tangential direction of the drive roller 17 .
A dust storage cover 24 is provided with a filter 24b at the rear thereof and is held by a frame (not shown).

Next, the operation mode of this cloth surface dust removal device 15 will be explained.

When the cloth 11 sent to the printing process moves, the cloth 1
Since the dust cloth 16, which is moving in the opposite direction to the moving direction of the cloth 1, slides against the surface of the cloth 11 in such a way that the oblique pile stands on end, the dust 12 adhering to the surface of the cloth 11 is removed by the dust cloth 16. The cloth 11 from which dust is removed is sent to the textile printing process.

On the other hand, when the dust cloth 16 with the dust 12 attached thereto moves to the circumferential surface of the drive roller 17 via the tension roller 20, the bristles on the surface of the dust cloth 16 tend to become flat due to the air flow from the air nozzle 23. Not only the dust 12 on the surface but also the dust 12 trapped between the bristles are easily blown away, and the dust 12 enters the dust storage cover 24 through the opening 24a and is captured by the filter 24b, and the dust 12 is removed from the dust storage cover. It will be collected within 24 days. At that time, as shown in Figures 4 and 5,
In addition to the jetted airflow (indicated by the black arrow) that is jetted by the air nozzle 23 on the surface of the dust removal cloth 16, an entrained airflow (indicated by the white arrow) is generated due to the ejector effect of this jetted airflow, and the dust is removed. Even if the airflow does not directly hit the dust removal cloth 16, the dust 12 attached to the dust removal cloth 16 can be blown off by the drawn-in airflow. By the way, when the nozzle diameter is 1.5 mm and air is injected with a wind pressure of 3 Kg/cm ² , the air volume of the entrained air flow is approximately 30 times the air volume of the jet air flow, which is sufficient to cover a length L of 100 mm and a width of W 120 mm. The dust 12 adhering to the dust cloth 16 could be blown away.

In addition, when the width of the cloth 11 is wide and the width of the dust removal cloth 16 is wider than the width W that allows dust to be blown away by one air nozzle 23, as shown in FIG. , a plurality of air nozzles 23 may be arranged in the width direction of the dust removal cloth 16, and each air nozzle 23 may be arranged in the width direction of the dust removal cloth 16.
The dust cloth 16 is reciprocated in the width direction in accordance with the moving speed of the dust cloth 16, and the dust adhering to the dust cloth 16 is blown away by the jet air flow and the drawn-in air flow, and is stored in the dust storage cover 24. and deal with it.

Then, the dust cloth 16 from which the dust 12 has been removed comes into sliding contact with the surface of the moving cloth 11 again, and the cloth 11 is successively removed.
1. Remove dust 12 from the surface.

Therefore, this cloth surface dust removal device 15 first removes the dust 12 adhering to the cloth 11 sent to the textile printing process from the surface of the cloth 11 to the dust removal cloth 16, and then removes the dust 12 adhering to the dust removal cloth 16. The dust is blown away into the dust storage cover 24 by using the air flow ejected from the air nozzle 23 in the diagonal direction of the bristles, so the dust removal cloth 16 can be circulated and used semi-permanently, which saves time and effort. Furthermore, the dust 12 on the surface of the cloth 11 is not removed by directly suctioning the entire width of the cloth 11, but is first allowed to adhere to the dust cloth 16, and then the dust 12 adhering to the dust cloth 16 is removed using the air nozzle 23. The airflow is blown away by the airflow ejected from the airflow and the entrained airflow generated by this ejection airflow. Remove dust by using output compressor and
It also consumes less power.

Also, depending on the type of cloth 11 (long pile cloth, short pile cloth, pile cloth, etc.), the resistance when the dust removal cloth 16 is in sliding contact increases or decreases, and when the resistance increases, the dust 12 can be removed easily, but it shifts the cloth 11 and has a negative impact on the printing process.
If the resistance is too small, it will not be possible to remove the dust 12 sufficiently, but the cloth surface dust removal device 15 of the embodiment
In this case, the resistance of the dust cloth 16 to the cloth 11 can be adjusted. For example, as shown in FIG. 6, by moving the tension roller 20 upward, the resistance of the dust cloth 16 can be reduced, and in this case, the subtension roller 19 can prevent the dust cloth 16 from loosening. It is necessary to move the contact surface adjustment bar 21 to the left as shown in FIG.
You can fine-tune its resistance by moving. Furthermore, in order to increase the resistance of the dust-removing cloth 16, it is sufficient to move the tension roller 20 downward and adjust the sub-tension roller 19 and the contact surface adjustment bar 21 in accordance with the type of cloth 11. The dust 12 can be effectively removed. Note that the tension roller 20 can be moved further upward so that it does not come into contact with the cloth 11, so that it is possible to deal with cloth that does not have dust attached or that should not be fluffed.

Furthermore, by connecting a dust collector to the end of the dust storage cover 24 of the embodiment, the dust 1 of the dust collecting cloth 16 can be more effectively removed.
2 may be removed.

Furthermore, in the embodiment, a device is shown that is installed on the belt roller 13 at the end of the belt conveyor 14 when sending the cloth 11 to the textile printing process. A roller having a rotating shaft and a dust cloth 16 provided on the outer periphery is press-adjustably pressed from above the cloth 11 and rotated so as to make the nap of the dust cloth 16 stand on end.
In order to remove dust attached to the dust cloth 16, an air nozzle and a dust storage cover may be arranged at a predetermined position above the roller where the dust cloth 16 bends.

<Effects of the invention> The cloth surface dust removal device according to this invention first removes the dust attached to the cloth sent to the textile printing process from the cloth surface and attaches it to the dust removal cloth, and then removes the dust attached to the dust removal cloth from the air nozzle. The dust is blown away into the dust storage cover using the airflow emitted in the diagonal direction of the bristles, so the dust cloth can be circulated and used semi-permanently without having to replace the cloth. In addition, instead of covering the entire width of the cloth and directly suctioning the dust on the surface of the cloth to remove it, the dust is first attached to the dust cloth, and then the dust attached to the cloth is removed using an air nozzle. The airflow is blown away by the airflow from the airflow and the entrained airflow generated by this airflow, and when combined with the fact that the airflow flows in a direction where it is easy to blow away the dust on the dust cloth, it is a small-output blower. Dust can be removed by using a compressor, and dust can be removed from cloth surfaces with low power consumption.
