Description

[Detailed Description of the Invention] This invention mainly relates to a device for removing foreign matter such as lint, which is installed in an automatic textile printing machine.

By the way, in the printing work where the desired pattern is dyed on the cloth to be printed, if there is foreign matter such as fuzz, dust, lint, etc. attached to the surface of the cloth, it is difficult to perform a good printing on the cloth to be printed. This results in serious problems such as non-uniform patterns or unusable defective products. For this reason, as a device for removing the foreign matter, conventionally, for example,
There has been proposed a structure in which a rotating roll brush is brought into contact with the surface of the cloth to be printed as it travels, and the foreign matter is brushed away by the brush. However, in such conventional devices, the rotating roll brush merely rubs the surface of the fabric to be printed, or simply sweeps foreign matter away from the surface of the fabric. However, the foreign matter removal efficiency is low, and in practice, the foreign matter cannot be completely removed.

In addition, as a device for removing minute foreign matter adhering to a running sheet, there is a device that has a fixed brush and an air suction port provided before and after the brush (for example,
"Screen Printing Handbook" May 31, 1978
3rd edition, Japan Screen Printing Technology Association P244
~245).

However, with this configuration, although it is effective in removing foreign matter such as fine dust attached to the running sheet, it is not effective in removing filamentous foreign matter such as lint, and therefore, complete foreign matter removal cannot be expected. There is a problem where I was told that I can't do it.

This invention consists of a rotating roller brush for capturing foreign particles that captures foreign particles on the fabric surface, a rotating roller brush for transferring foreign particles that transfers the captured foreign particles on the roller brush, and a case-shaped rotating roller brush that covers the rotating roller brush for transferring. Consisting of a foreign matter container and a drive mechanism for rotating both rotating roll brushes in the same direction,
The two rotating roll brushes are mounted substantially parallel to each other at a required distance between the two brush members, and a large number of ventilation holes are provided around the entire circumference of the shaft of the rotating roll brush for transferring foreign matter. At the same time, a non-rotating air duct is tightly fitted into the shaft portion of the roll brush, and the air duct of the rotating roll brush for transferring foreign matter is provided at a position inside the foreign matter container in the air duct. On a fabric surface in an automatic textile printing machine, a large number of ventilation holes are formed to communicate with the pores, and the inside of the air duct and the air source side are communicated via an air flow path. It is related to a foreign matter removal device, and its purpose is to completely remove foreign matter on the fabric surface, thereby improving the good post-processing effect such as improving the printing finish of the fabric. .

Hereinafter, details of the present invention will be explained based on embodiments shown in the drawings.

Figures 1 and 2 show an automatic flat screen printing machine 2 for applying a desired print to a fabric (fabric to be printed) 1, and a device for removing foreign matter such as lint attached to the printing surface of the fabric 1. It shows the arrangement state with device 3,
The textile printing machine 2 is composed of a cloth feeding section 4 for the fabric 1, a printing section 5 for the fed fabric, and a dryer 6 for the printed fabric. An endless belt 7 that is intermittently fed at intervals of , a plurality of printing heads 8 disposed above the belt, and a gluing device disposed below the cloth supply section 4 side. 9 and a belt washing device 10 disposed below the dryer 6 side. Therefore, the fabric 1 ₁ fed from the cloth feeding section 4 side while being subjected to the required width adjustment and spreading action is ,
The fabric 11 is stretched at a fixed position on the endless belt 7 through the tensioning glue, and in that state, the fabric ₁₁ is intermittently transferred to the dryer 6 side as the endless belt 7 is conveyed. At the same time as the endless belt 7 is stopped, the printing head 8 is lowered and the squeegee 8a sequentially applies the required impressions to each of the lower fabrics ₁₁ , and then the printing process is performed. Fabric 1 ₂ is dryer 6
The apparatus is configured to obtain a pattern-dyed fabric product ₁₃ through the necessary drying process within the apparatus.

When the device 3 of the present invention is installed and used in the automatic textile printing machine 2 described above, as shown in the figures, the fabric 1 ₁
It is sufficient to establish a relationship in which the endless belt 7 is operated only when the endless belt 7 is intermittently conveyed at an appropriate position after the printing head 8 starts the printing process after the printing head 8 starts printing. That is, the device 3 of the present invention has a suitable support 1 in a direction perpendicular to the direction of transport of the above-mentioned feeding fabric ₁₁ .
A case-shaped foreign object container 12 constructed through 1
, a rotating roll brush 14 for trapping foreign matter on one surface, and a rotating shaft of the roll brush in the housing ₁₂ , which is also perpendicularly mounted in the housing via a suitable bearing 13. A non-rotating air duct 15 installed approximately parallel to the axial direction of the air duct 14a and at a required interval, a rotating roll brush 16 for transferring foreign matter fitted tightly onto the outer peripheral surface of the air duct, and the above-mentioned A drive mechanism 2 consisting of a motor 17, a pulley 18, and a transmission belt 19 for rotating both roll brushes 14 and 16 in the same predetermined direction, respectively.
It is composed of 0. Further, a rotating roll brush 16 for transferring foreign matter is provided on the upper part of the foreign matter container 12.
A rotating lid 12a is provided which opens and closes the upper part of the container, and the above-mentioned anti-printing head 8 of the container is provided.
A breathable mesh plate 12b is attached to the side wall, and the printing head 8 side is open for engaging the brush members 21 and 22 of the roll brushes 14 and 16. Further, the inside of the air duct 15 and the air source (not shown) side are communicated via a suitable air flow path 23, and furthermore, the inside of the container 12 in the air duct (in the example shown) is connected to the inside of the air duct 15 and the air source (not shown) (on the opposite side from the position of the rotating roll brush 14 for capturing foreign objects)
A large number of ventilation holes 15a are arranged in the longitudinal direction at the position. Further, a large number of ventilation holes 16a are bored around the entire circumference of the shaft portion of the rotary roll brush 16 for transferring foreign matter, which can communicate with each of the ventilation holes 15a in the air duct. Therefore, when the compressed air 24 is being pumped into the air duct 15, when the rotary roll brush 16 for foreign matter transfer is rotated by the drive mechanism 20, the air 24 is transferred to both the air duct and the roll brush. It is configured to eject into the interior of the container 12 through the ventilation holes 15a and 16a. Also,
Both brush members 21 and 22 are made of animal/vegetable fibers or chemical fiber materials, and their shape is usually a straight line as shown in FIG. The brush member 21 of the rotating roll brush 14 for capturing foreign matter 25 adhering to the fabric 1 ₁ has a shape in which linear portions 21a and uneven portions 21b are alternately formed, as shown in FIG. 5, for example. The trapping efficiency of the foreign matter 25 may be improved by using the following. In addition, both roll brushes 1
4 and 16 are rotated in the same predetermined direction, and this predetermined direction refers to the direction in which the feed is transferred to the printing head 8 by the endless belt 7, as shown by the arrow in FIG. This refers to the rotation direction in which the brush member 21 of the rotary roll brush ₁₄ for capturing foreign matter that comes into contact with the surface of the sent fabric 1 is opposite to the direction in which the fabric ₁₁ is transported on the side in which it comes into contact with the fabric surface.

The foreign matter removal action of the device of the present invention will be explained below.

As described above, the fed fabric ₁₁ fed to the printing section 5 side by the endless belt 7 in the textile printing machine 2 is subjected to printing processing multiple times by the printing head 8. Although the feeding fabric ₁₁ is transferred intermittently, the device 3 of the present invention operates only during the intermittent transfer of the fed fabric 11. Now air duct 15
While the feeding fabric ₁₁ is being transferred with the compressed air 24 being pumped inside, both roll brushes 14 and 16 are rotated in the above-mentioned predetermined directions by the drive mechanism 20. If a foreign substance 25 is attached to one side of the fabric ₁ , the foreign substance 25 is attached to the third side.
As shown in the figure, first, it is captured by the brush member 21 of the rotating roll brush for capture. next,
The captured foreign matter ₂₅₁ on the brush member 21 is transferred into the container 12 by the brush member 22 of the rotating roll brush for foreign matter transfer that engages with the brush member. are disposed substantially parallel to each other, the rotation directions of the engaging portions of the two are opposite to each other. Therefore, the brush member 22 for foreign matter transfer has a direction opposite to the brush member 21 for capturing foreign matter. ₁ into the container 12
It works to sweep it away inside. Also,
Trapped foreign matter 25 ₁ brushed off by the above action
However, the transferred foreign matter 252, which has not fallen and is attached to the transfer brush member 22, is moved inside the container ₁₂ by the compressed air 24. be forcibly detained. That is, as described above, the ventilation hole 15a in the non-rotating air duct 15 and the ventilation hole 16a in the rotating roll brush 16 for transferring foreign matter communicate with each other at a position on the inside side of the container 12, so that the inside of the air duct 15 When the compressed air 24 that has been force-fed is ejected through both the ventilation holes 15a and 16a, the transferred foreign matter ₂₅₂ is blown away into the container 12, and the blown foreign matter is At the same time, the blown air ₂₄₁ is discharged to the outside of the container through the mesh plate 12b of the container. Note that the foreign matter 25 ₃ accommodated in the container 12
This can be easily removed by opening the rotating lid 12a.

As described above, with the device of the present invention, it is possible to completely remove foreign matter (especially filamentous foreign matter) on the fabric surface. By arranging a rotating roll brush that captures foreign matter and a rotating roll brush that transfers the captured foreign matter on the brush to the foreign matter container side, the captured foreign matter on the capturing rotating roll brush can be completely removed and stored. Therefore, it is possible to prevent problems such as foreign matter once captured re-adhering to the surface of the fabric being transferred due to the rotation of the brush, which is the case with roll brushes in conventional devices. It is possible, and by this,
This has practical effects such as improving post-processing effects such as improving the printing finish of fabrics. Further, according to the configuration of the device of the present invention, the foreign matter on the brush member of the rotating roll brush for foreign matter transfer can be completely contained in the foreign matter container by compressed air, so that the foreign matter on the brush can be captured by the foreign matter. Since the captured foreign matter can be completely removed without re-adhering to the rotary roll brush side, the above-mentioned problems with the conventional device can be reliably solved, and this is an excellent effect.
