Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention continuously removes impurities such as lint and fluff adhering to the surface of fabrics such as textiles and lace, or of belt-shaped products such as films and paper products. It relates to a device for.

[Background of the Invention] For example, the process of pre-treating a long fabric such as an industrially produced fabric or lace, and then printing the fabric is as follows:
It is well known to perform a pretreatment by burning, desizing, scouring, and bleaching, and then to dye the pretreated fabric continuously in a printing machine. However, if there are impurities such as fluff, thread waste, or fiber carbide generated during the burning process on the surface of the fabric that is applied to the above-mentioned printing machine, the impurities will cause defects in the dyeing, resulting in poor printing quality. It turns out you can't do it. For this reason, conventionally, in order to remove impurities such as thread waste that adhere to the surface of the fabric immediately before printing, a blower or the like has been used to blow away the impurities on the surface of the fabric. Although it has been considered, there is no certainty that it can be used as a means of removing impurities.

[Purpose of the invention]

The present invention has been made in view of the above, and by bringing an adhesive roll whose surface is coated with an adhesive into contact with the surface of a belt-shaped product such as a fabric or film, impurities attached to the fabric can be removed. The object of the present invention is to provide a continuous cleaning device for strip-shaped products that can be continuously and reliably removed and removable using an adhesive.

[Embodiments of the invention]

The present invention will be explained in detail below based on embodiments shown in the drawings.

1 is a main roll rotated by a motor shown in the figure, and the surface of this main roll 1 is made of synthetic colloid. In the rotational circumferential direction of the main roll 1, an adhesive applicator 2, an adhesive doctor knife 3, a shower 4, a cleaning brush 5, and a draining doctor roll 6 are arranged in this order. The adhesive applicator 2 has a main roll 1
This is to overlay an appropriate amount of adhesive at the right time on the surface of the main roll 1. For example, a water-insoluble acrylic adhesive contained in an adhesive tray 2a is applied to the surface of the main roll 1 by an applicator roll 2b. can do. This applicator roll 2b is not always in contact with the main roll l, but by operating the tip of the arm 2C supporting this applicator roll 2b with an appropriate drive means, the arm 2
C operates with the fulcrum 2d as the fulcrum, and the applicator roll 2b can apply the adhesive to the main roll 1 at an appropriate time by contacting or not contacting the main roll 1.

The adhesive doctor knife 3 is, for example, a squeegee for uniformly and quantitatively adjusting the adhesive applied to the surface of the main roll 1. The shower 4 is a shower for washing away impurities such as lint adhering to the adhesive-coated surface of the main roll 1, and sprays purified water toward the surface of the main roll 1. The cleaning brush 5 is for brushing to remove impurities on the surface of the main roll 1 that were not removed by the shower.The cleaning brush 5 is held in a movable adjustment frame 5&, and its adjustment screw 5b As a result, the contact force between the cleaning brush 5 and the main roll 1 can be increased to v4. The doctor roll 6 for draining is composed of, for example, a rubber roll or a sponso roll for removing moisture adhering to the main roll 1. 7 is a guide roll for the fabric 8; 9 is a drawer roll for the inserter 8; this guide roll 7 and the drawer roll 9
The fabric transferred between the main roll 1 and the main roll 1 is arranged so as to be in contact with the surface of the main roll 1. Note that the guide roll 7 described above can be moved so as to adjust the bonding area between the fabric 8 and the main roll 7, that is, as shown by the chain line.

The above is the structure of this embodiment. Next, to describe its operation, when the applicator roll 2b is brought into contact with the coating surface of the main roll 1 and the main roll 1 is rotated, the adhesive tray 2
The adhesive in a is applied to the main roll 1, and a certain amount of adhesive coating layer is formed on the main roll 1 by the doctor knife 3. By running the fabric 8 in such a way that it comes into contact with the surface of the main roll 1, impurities such as lint and carbide attached to the surface of the fabric are transferred to the adhesive coating layer of the main roll 1. removed. The impurities transferred to the adhesive coating layer of the main roll 1 are
The water on the main roll 1 that has been removed by the shower 4 and the cleaning brush 5 is drained by a draining doctor roll 6, and is brought into contact with the fabric 8 again to remove impurities on the fabric.・This main roll 1 rotates. However, when the viscosity of the adhesive coating layer on the main roll 1 decreases due to repeated contact with the fabric, the coating roll 2b is reapplied to the main roll 1.
Contact with to replenish viscosity. In addition, the guide roll 7 is operated to adjust the amount of contact between the transported fabric and the main roll to an effective position m* by checking the degree of impurity removal on the surface of the fabric.

[Summary of the invention]

As described above, the present invention provides a main roll whose entire peripheral surface is coated with an adhesive by an adhesive coating means, and a workpiece that is brought into contact with the main roll coated with the adhesive. It has a strip-shaped product guide roll that guides the strip-shaped product, and a cleaning means for the main roll that removes impurities transferred from the strip-shaped product to the surface of the adhesive layer due to contact between the strip-shaped product and the adhesive on the main roll. This is a continuous cleaning device for strip-shaped products.

〔Effect of the invention〕

Therefore, according to this device, the impurities attached to the light surface of the continuously transported long strip product can be continuously and effectively removed by the main roll to which the adhesive is applied. be.
