1. Field of the Invention
The present invention relates to layering devices, systems and methods, specifically to devices, systems and methods for applying layers to substrates using belts and rollers.
2. Description of the Related Art
In the related art, it has been known to use wrapping equipment to apply layers of materials to a substrate. Traditional composite tube wrapping processes are typically very labor intensive. Traditional methods require a manual application of a tacky substance on a heated mandrel; typically this tacky substance is non-supported adhesive which is ironed onto the mandrel. After the application of the tacky substance, the composite material is manually and smoothly applied to the sticky mandrel. The composite material has to be free of any wrinkles as it applied to the mandrel. Subsequent to these two steps the mandrel with the composite material is placed on a device that rolls the composite material around the mandrel. Some improvements have been made in the field. Examples of references related to the present invention are described below, and the supported teachings of each reference are incorporated by reference herein:

The material layering device 10 includes a first pinning roller 16 and a second pinning roller 18 disposed near the first pinning roller 16 and oriented substantially parallel thereto. The illustrated rollers 16, 18 are elongated cylinders configured to rotate about an axis, freely, under power, under friction, or any combination thereof. Accordingly, the rollers 16, 18 may be rotated as desired in the operation of the illustrated device.
The device 10 also includes a return system 24 disposed near the first pinning roller 16 and the second pinning roller 18. The illustrated return system 24 configured to permit repeatable operation of the device 10 by providing structure through which the device 10 may cycle through a layering procedure. This may be done through a continuous rotation cycle, through steps rotations, through forward-reverse cycles, and any combinations thereof.
The illustrated return system 24 includes a plurality of rollers 26 disposed about the first pinning roller 16 and the second pinning roller 18 and forming a virtual polygon encompassing both the first pinning roller 16 and the second pinning roller 18. In the illustrated case, the virtual polygon is a triangle formed enclosing the first and second pinning rollers 16 and 18. The illustrated plurality of rollers 26 consists of three rollers 26.
The illustrated device also includes a belt 28. The illustrated belt 28 is a hollow cylindrical flexible material wrapped about the rollers as shown and subject to a desired tension. The illustrated belt 28 is a complete circuit.
The illustrated belt 28 includes a first loop portion 32 disposed between and protruding beyond the first pinning roller 16 and the second pinning roller 18. The illustrated belt 28 further includes a feed portion 36 coupled to the first loop 32 and extending outwardly from the second pinning roller 18 opposite the first loop 32 and providing a surface 38 upon which a sheet 12 can be placed. In addition, a second portion 48 disposed about the return system 24 and coupled to the first loop portion 32, wherein the second portion 48 wraps about the first pinning roller 16 greater than about a 90 degree arc. It is understood that during operation of the illustrated device 10, the physical portions of the belt 28 change names and operation, as the belt 28 is rotated, to match the position and function of such positions at any given time.
The illustrated second pinning roller 18 is larger than the illustrated first pinning roller 16. This advantageously reduces a total area occupied by the device 10 and allows for a return system 24 configuration as shown.
The illustrated device 10 also includes a belt 28, wherein the belt 28 has a first loop portion 32 disposed between and protruding beyond the first pinning roller 16 and the second pinning roller 18, wherein the first loop portion 32 wraps about an intended substrate 14 along an arc greater than about 300 degrees 44 and wherein the first loop portion 32 wraps about an intended substrate 14 along an arc greater than about 320 degrees 46. The material layering device 10 further includes a feed portion 36 coupled to the first loop 32 and extending outwardly from the second pinning roller 18 opposite the first loop 32 and providing a surface 38 upon which a sheet 12 can be placed. In addition, a second portion 48 disposed about the return system 24 and coupled to the first loop portion 32, wherein the second portion 48 wraps about the first pinning roller 16 greater than about a 90 degree arc.
The illustrated substrate 14 is held within the belt and pinned in place such that tension from the belt is applied over a substantially greater arc 44 than that of the prior art. A variety of arc lengths 46, 70, and 72. Wherein a distance 20 between the two pinning rollers is less than a diameter (two times the radius 22), the arc length will be greater than about 180 degrees or half the circumference of the substrate. Further, under tension, the substrate object will not be permitted to traverse the pinning rollers 16, 18 and therefore tension may be maintained. It is understood that as the distance 20 between >pinning rollers 16, 18 approaches the diameter of the intended substrate 14 there may be a point wherein natural flexibility in one or more portions of the device may permit the substrate to traverse the pinning rollers 16, 18. Accordingly, one skilled in the art would be able to without undue experimentation, tune the device to appropriate settings, should an arc length of about 180 degrees be desired.
The illustrated device 10 also includes an adjustment mechanism coupled to one of the first pinning roller 16, second pinning roller 18, and the return system 24, wherein the adjustment mechanism enables selective loosening of the belt 28. The adjustment mechanism includes a lateral translation mechanism 62 for laterally adjusting a position of one of the plurality of rollers 18, 26 of the return system 24. Such may include release latches and tracks coupled to one or more rollers or other devices configured to permit the release of tension on the belt.
The illustrated material layering device also includes a third pinning roller 50 disposed near the first pinning roller 16 and near the second pinning roller 18 and positioned to apply pressure to the belt 28 against a substrate 14 when the device 10 is in use. The third pinning roller 50 compresses an intended substrate 14 against the second pinning roller 18. Advantageously, the third pinning roller 50 provides additional pressure against the belt and therethrough against the substrate.
In one embodiment, the third pinning roller is adjustable in position, rotation freedom, and/or tension thereby enabling an operator to fine-tune pressure conditions during use. Such may advantageously permit an operator to handle variations in operating conditions such as but not limited to: variations in the shape, size, constituency, or other properties of substrates and/or sheets (or layering materials); variations in environmental conditions such as but not limited to heat, humidity, and the like; desired layering configurations; and combinations thereof.
In operation of one embodiment of the material layering device 10, a user loosens the belt 28 by adjusting the lateral translation mechanism 62 of the adjustment mechanism and couples a substrate to the first loop portion 32 in between the first and second pinning rollers 16, 18. The user then adjusts the lateral translation mechanism 62 and secures the substrate 14 within the first loop portion 32. The user then couples a sheet 12 to the surface 38 of the feed portion 36. The sheet is then attached to the substrate, wherein the substrate 14 and the pinning rollers 16, 18 are in contact at least 180 degrees. The user then adjusts the lateral translation mechanism 62 of the adjustment mechanism to release the substrate 14 from the first loop portion 32 of the device 10
It is understood that the above-described embodiments are only illustrative of the application of the principles of the present invention. The present invention may be embodied in other specific forms without departing from its spirit or essential characteristics. The described embodiment is to be considered in all respects only as illustrative and not restrictive. The scope of the invention is, therefore, indicated by the appended claims rather than by the foregoing description. All changes which come within the meaning and range of equivalency of the claims are to be embraced within their scope.
For example, although the figures illustrate a first and second pinning rollers and a plurality of routing rollers, one skilled in the art would appreciate that the pinning rollers and routing rollers (return system) may vary in size, configuration, design, length, width, diameter, and still perform their intended functions.
Additionally, although the figures illustrate a circular substrate, one skilled in the art would appreciate that the device may include a substrate that varies in size, shape, design, configuration, length, width, diameter, and still perform its intended function.
It is also envisioned that the sheet may be but not limited to: a composite material, rubber material, metal material, metal alloy material, plastic material, carbon fiber material, and still perform its intended function.
It is expected that there could be numerous variations of the design of this invention. An example is that the belt may be a rectangular sheet instead of being cylindrical and the return system may include a pair of opposing rollers that roll the belt up during forward and backward cycles of operation.
Finally, it is envisioned that the components of the device may be constructed of a variety of materials including but not limited to metals, ceramics, composites, wood, textiles, fibers, plastics, and the like and combinations thereof.
Thus, while the present invention has been fully described above with particularity and detail in connection with what is presently deemed to be the most practical and preferred embodiment of the invention, it will be apparent to those of ordinary skill in the art that numerous modifications, including, but not limited to, variations in size, materials, shape, form, function and manner of operation, assembly and use may be made, without departing from the principles and concepts of the invention as set forth in the claims. Further, it is contemplated that an embodiment may be limited to consist of or to consist essentially of one or more of the features, functions, structures, methods described herein.
This invention claims priority, under 35 U.S.C. § 120, to the U.S. Provisional Patent Application No. 60/868,645 to Carlston filed on Dec. 5, 2006, which is incorporated by reference herein.
