Description

FABRIC TREATMENT APPARATUS COMPRISING EASILY REMOVABLE TREATMENT TUBES}

Materials such as fabrics are characterized by a wide range of functional and aesthetic properties. Of particular importance among these properties is the fabric surface feel or “hand”. The importance of a good hand to the fabric is disclosed and described in US Pat. Nos. 4,918,795 and 4,837,902, both to Disschler, which are incorporated herein by reference in their entirety.

Good tactile properties of fabrics are usually obtained by conditioning prepared fabrics (ie, de-sized, bleached, mercerized, dried fabrics). Conventional methods of conditioning the prepared fabrics include roughening the final product with a cylindrical roll that is driven grainlessly and rotatably driven. Such roll treatments provide a very effective and rapid conditioning method by allowing the treatment of continuous webs of fabrics with roughened surfaces. The cylindrically formed rolls contact virtually all areas of the target fabric web regardless of the speed of the web on the rolls. Thus, these methods have proven to be an efficient and low cost method in the treated textile industry. Examples of such cylindrical roll treatments can be found in U.S. Patent No. 5,752,300 to Discler and U.S. Patent No. 3,973,359 to Spencer, which are incorporated herein by reference in their entirety. Processes such as sueding, sanding, napping and brushing (with soft or strong bristles) are performed with such cylindrical rolls.

Both sueding and sanding finish the woven fabric by polishing one or both surfaces of the target fabric using sandpaper or similar abrasive material (ie diamond grit) to cut and lint the fibers of the constituent yarn in the fabric. It is about processing. Fabrics produced through such treatments generally exhibit closely fluffed naps that produce a smooth and smooth surface texture such as suede leather. Such operations are typically performed by specialized fabric sueding or sanding machines, where the fabric is passed under one or more processing rolls, which are covered with sandpaper or similar abrasive material and applied to the movable fabric web. Rotate at differential speed.

The napping also relates to surface-raising treatment for the target fabric. Such treatments provide fabrics that exhibit a softer feel, improved drapeability, thicker fabric thickness, and better overall durability. Generally, a napping machine utilizes a rotatablely driven cylinder, such as card clothing, including a peripheral wire tooth, wherein the fabric runs under constant tension through the cylinder.

Such cylindrical rolls are provided in a standard fabric processing apparatus through a relatively simple lay-in process with a coupling of the drive belt and the locking mechanism on one or both ends of the roll, thereby laiding in. To ensure that there is virtually no movement from position. However, such a method is initially quite cumbersome in that the rolls are generally heavy in weight and width and require a large amount of manpower to run through and / or around potentially delicate fabric processing apparatus machines. If a different treatment surface is required for different fabric types, or if the treatment surface has been sufficiently eroded or worn out to be ineffective when treating the target fabric surface, or exchange, replace, replace, or otherwise remove such rolls If any other necessity for this is necessary, this has turned out to be a problem in the past. Thus, the lighter weight, which facilitates the operation of the cylindrical processed article and facilitates the placement, is very advantageous in the industry, especially when removal is rather simple, unobstructed, and inexpensive (in terms of labor and time). It is advantageous to To date, there has been no such improvement in the industry.

Summary of the Invention

Accordingly, it is a first object of the present invention to provide an easy and simple method for replacing and / or removing a cylindrical treated article from a fabric processing apparatus. A further advantage of the present invention is that it provides a tubular treated article that is substantially hollow and thus lightweight, but provides a sufficient solid surface for the desired fabric processing. Another object of the present invention is to provide a method for easily removing such lightweight tubular textile treated articles from such devices. Thus, the invention comprises at least one polishing tube positioned on an axial axis and having two separate ends, the first end being coupled to the beveled drive mechanism, the second end being coupled to the beveled clamp mechanism, The tube includes a fabric processing apparatus that is removed from the fabric processing apparatus by separating the second end from the beveled clamp mechanism and moving the treatment tube axially away from the first end. The invention also includes at least one polishing tube positioned on the shaft and having two separate ends, the first end being coupled to the beveled drive mechanism and the second end being attached to the coupling mechanism. A textile processing device coupled to a beveled device, wherein the tube is removed from the textile processing device by separating from the coupling mechanism and moving the processing tube axially away from the first end.

These and other advantages will be in part apparent and in part pointed out in the description which follows, particularly within the non-limiting preferred embodiments shown and described with reference to the accompanying drawings.

The present invention relates to a treatment tube that is easily removable from a fabric treatment apparatus to facilitate roll change for treatment modification, cleaning, disposal or any other desired purpose. Such treatment tubes are generally hollow and can be coated with any standard textile treatment surface, including sandpaper, diamond grits, wires, brushes, and the like. As such, the ability to easily remove, replace, or place such treatment tubes provides a significant time saving and cost advantage for the manufacturer.

As shown in FIG. 1, the web 8 of the fabric is moved through an apparatus 9 having two separate processing chambers 10, 12 and an intermediate chamber 100. After the web 8 enters the first processing chamber 12, it passes through the idler roll 22 and is directed to the drive rolls 24, 26, which are driven by a synchronous belt (not shown). By interlocking with each other in a one-to-one relationship. Enclosing the drive roll sufficiently to pull the web is accomplished by directing the web onto the idler roll 25. The fabric is then directed onto an idler roll 28 with load cell blocks 27 mounted on each end of the idler roll 28. The output from the load cell block 27 (used for the same purpose as the dancer roll) is used to adjust the relative speeds of the drive rolls 24 and 26 and the next pair of drive rolls 32 and 32a, The tension of the web 8 is controlled.

The web is then directed to contact the polishing tubes 11, 11a disposed between the idler rolls 29, 29a. Such treatment tubes 11, 11a may be coated with any standard textile treated surface, such as sandpaper, diamond grit, or the like, or other treated articles such as brushes, wires, card-cloth, or the like may be attached thereto. In addition, such treatment tubes 11 and 11a are made of a solid material such as metal, thermoplastic, wood, or the like. Preferably, such tubes 11, 11a are made of steel. The figure shows the specific orientation of the web 8 to the treatment tube 11, where one side of the web is first contacted by the treatment tube 11 and then the other side is contacted. However, the idler roll 29 and the treatment tube 11 can be symmetrically oriented so that the web path can be altered by passing the web to either side of the treatment tube 11 and thus desired for a particular fabric style. The front or back side of the web is treated by a particular treatment tube 11 as desired.

After processing in the chamber 12, the web 8 passes into the intermediate chamber 100 and passes below the scroll roll 30 up to the idler roll 31, which is loaded with a load cell block ( It is mounted at each end on 27a), whereby the tension of the web 8 is measured and compared with the tension measured by the load cell 27 as a quality check. Next, the web is directed to the drive roll 32, the idler roll 31a, and the drive roll 32a interlocked in a one-to-one relationship with the drive roll 32. Subsequently, the web 8 passes under an idler roll 31b with a load cell block 27b at each end, which load cell block 27b tensions the web 8 in the processing chamber 10. Act to control it. The output from the load cell block 27b is used to adjust the relative speeds of the drive rolls 32 and 32a and the next pair of drive rolls 34 and 36 to control the tension of the web 8 in the chamber 10. do.

The web passes under a scroll roll 30a that acts to further open the web before entering the processing chamber 10. This opening is particularly desirable when the tension used in the processing chamber 10 is less than the tension used in the processing chamber 12.

Next, the fabric web 8 enters the processing chamber 10, where the spaced idler rolls 29a act to contact the web with respect to the processing tube 11a. Again, the figure shows the specific orientation of the web to the treatment tube 11a, where one side of the web is first contacted by the treatment tube 11a and then the other side is contacted. However, the idler roll 29a and the treatment tube 11a are symmetrically oriented so that the web path can be altered such that the front or back side of the web is treated by the specific treatment tube 11a as desired for a particular fabric style. have.

After treatment in the chamber 10, the fabric is directed around an idler roll 30b with a load cell block 27c at each end, whereby the tension of the web 8 is measured by the load cell block 27c. Then, it is compared with the tension measured by the load cell 27b as a quality test. Subsequently, the webs 8 are directed through the idler rolls 33 to the drive rolls 34 and 36, which are interlocked with one another in a one-to-one relationship by means of synchronous belts (not shown). do. Enclosing the drive roll sufficiently to pull the web is performed by directing the web onto the idler rolls 35, 38. Next, the web is directed away from the device 9.

The entire device 9 is sealed to prevent leakage of lint to the surroundings. Slidable windows 14, 16, 18, 20 allow access and viewing of the treatment area. The lint produced by the contact of the web 8 with the treatment tube 11 falls into the intermediate chamber 100 and is removed by ductwork (not shown) attached thereto. Most preferably, the outer surface of such treatment tubes 11, 11a is coated with diamond grit of an electroplated nickel matrix. Moreover, the tubes 11 and 11a are removable through the through doors 13 and 13a which rotate about the hinges 15 and 15a. Such a configuration makes it possible to replace such tubes 11, 11a with a minimum of time.

As shown in FIG. 2, the tube 102 is hollow and has an internal bevel of 15 ° on each end. The urethane rubber cushions 104 and 106 cover each end of the tube to act as a transmission element, preventing metal to metal contact and consequently preventing wear. Accordingly, such rubber caps 104 and 106 may be driven by a drive cone 108 or mating due to tube bending resulting from large web tensions that cause squirming and rapid wear of the contacting metal surfaces. It is very important in that such lightweight tubes make use of large web tensions without damaging the tube bevels. The tube is driven by pressure coupling (via cushions 104 and 106) with a drive cone 108 having a mating bevel of 15 °. Guide shaft 110, which acts to support and guide tube 102 during replacement, extends from drive cone 108. The guide shaft 110 extends backwards through a drive cone 108 supported by a pair of bearings (not shown) located in a bearing housing 112 mounted to a first bulkhead 114. Driven by a drive sprocket 118 (drive motor and belt, not shown) connected to the guide shaft by the clutch 116. The pressure contact between the tube and the drive cone 108 is in both freewheeling clamp cones 120 (both FIGS. 2 and 3) including a pair of angular contact bearings 120a mounted on the clamp shaft 122. Shown). The clamp cone 120 is driven by the air cylinder 123 past the clamp shaft 122 and into the processing tube 102. The auxiliary pressure (if there is a loss of air pressure) is generated by the disc shaped disc spring 124 surrounding the clamp shaft 122 and embedded in the cylinder mount 126. The clamp shaft 122 is supported by the air cylinder 123 and the sleeve bearing 128. The cylinder mount 126 is bolted to the door 127 supported by the door hinge 129 and the latch bar 130. Both hinge 129 and latch bar 130 are mounted to second bulkhead 132. As shown in FIG. 4, when the latch bar 130 is open, the door 127 can pivot at least 90 °, preferably longer, such that the treatment tube 102 is formed of the first bulkhead 132 and Allow extraction and replacement through access hole 132a.

5 shows an alternative drive mechanism for the tube 102. As in FIG. 1, the tube 102 is hollow and has an internal bevel of 15 ° on each end. The tube is driven by pressure coupling with a drive cone 142 having a mating bevel of 15 °. The drive cone is supported on the drive shaft 148 by the spherical bearing 142a. Spherical bearings accommodate axial misalignments that can occur when the tube is bent by high side loads imposed by contact with the web under high tension. The drive cone 142 is connected to the drive disk 150a by a compressible rubber ring 150. Other coupling means may be used, for example pins or keys. The drive disk 150a is keyed to the drive shaft 148 and is connected to the drive motor 140 by a coupling 141 in the coupling housing 138. The drive shaft 148 is supported by a first bearing 146 and a second bearing (not shown), all of which are housed in the housing 144. The guide shaft 152 supporting the tube 102 at the time of mounting is screwed into the drive shaft 148 and also acts to retain the spherical bearing 142a. In addition, a gasket (not shown) may be employed between the tube 102 and the drive cone 142 to further cushion and protect the drive surface.

The scope of the invention is not limited to the specific embodiments and / or drawings described herein, but rather is intended to be defined by the appended claims and their equivalents.
