In the drawings:
For purposes of description herein, the terms “upper,” “lower,” “right,” “left,” “rear,” “front,” “vertical,” “horizontal,” and derivatives thereof shall relate to the invention as oriented in
As illustrated in
The punch press 14 of the panel forming unit 10 is configured to press guide lines 40 and guide indents 42 into a surface of the panel media 22. The guide lines 40 are configured to define locations for defining drain troughs 44, drain apertures 50, attachment flanges 46, connecting members 48 and other fastening portions of the cladding panels 32 that will be formed within the panel media 22. These fastening portions of each cladding panel 32 are configured to cooperate with adjacent cladding panels 32 to provide secure attachment points and substantially direct water down the drain troughs 44 and through drain apertures 50, as well as preventing leakage between the cladding panels 32 once installed. The punch press 14 can include a powered conveyor 52 and various rollers 54 to assist in moving the panel media 22 through the panel forming unit 10. Also, in various embodiments, the individual punch press 14 mechanisms can include various types of presses 56, such as C-frame presses, portal-type presses, among other types of presses 56.
The stamping die 16 of the panel forming unit 10 is configured to stamp or press a predetermined relief pattern 70 within the panel media 22. The stamping die 16 is configured to define the relief pattern 70 within the panel media 22 such that the predetermined texture 30 formed by the embossing unit 12 remains at least partially defined within the predetermined relief pattern 70 and the formed cladding panel 32. As described above with respect to the predetermined texture 30 formed by the embossing unit 12, the predetermined relief pattern 70 defined by the stamping die 16 can be of a pattern of any one of multiple cladding materials that can include, but is not limited to, wooden shake panels, slate panels, concrete panels, terra cotta tiles, thatched roof layers, and other cladding and roofing material patterns. The stamping die 16, similar to the punch press 14, can include a feeder 72, such as a servo feeder, or other mechanism configured to deliver the panel media 22 through the panel forming unit 10. It is contemplated that the stamping die 16 is able to stamp between about 15 to about 20 panels per minute, although more stamps per minute are also contemplated.
The shear press 18 of the panel forming unit 10 is configured to cut the panel media 22 into individual cladding panels 32 that have a predetermined length. The shear press 18 is configured to cut the panel media 22, such that each cladding panel 32 includes substantially the same texture 30, relief pattern 70, guide lines 40 and guide indents 42. In this manner, as the cladding panels 32 are installed on a structure, substantial uniformity of the cladding panels 32 ensures a substantially tight fit between the fastening portions of each of the cladding panels 32, as described above. It is contemplated that the texture 30 and relief pattern 70 of the cladding panels 32 can vary among cladding panels 32. Such variation can add to the natural aesthetic of the cladding panels 32 formed through the disclosed method. The shear press 18 can be similar to a stationary shear or hydrex design or other similar shear press 18.
The roll former 20 of the panel forming unit 10 is configured to form at least one flange, such as an attachment flange 46, of each of the cladding panels 32 to provide the fastening portions of each of the cladding panels 32. As illustrated in
It is contemplated that the panel forming unit 10 can include additional mechanisms to assist in the delivery of the panel media 22 through the panel forming unit 10. These mechanisms include, but are not limited to, loop controls 82, feeders 72, conveyors 52, rollers 54, support tables 58, and the like. The loop controls 82 of the panel forming unit 10 are configured to limit the bunching and flexing movement of the panel media 22 as the panel media 22 is moved through the panel forming unit 10. This bunching and flexing can occur due to the panel media 22 being steadily fed into the panel forming unit 10, while certain mechanisms, such as the shear press 18, punch press 14 and stamping die 16 require the panel media 22 to temporarily stop to perform the various pressing, punching and stamping functions. The loop control 82 substantially maintains the position of the panel media 22 so that it can be properly fed through the panel forming unit 10.
The above-described panel forming unit (or cladding panel assembly) 10, can be operated according to the various methods described herein to create various cladding panels 32 having a variety of finishes, shapes, textures 30 and configurations that include, but are not limited to, slate tile cladding panels 32, as shown in
Having generally described the panel forming unit 10, and referring now to
Step 504 of the method 500 includes placing the panel media 22 proximate the panel forming unit 10 and feeding an end of the panel media 22 into the panel forming unit 10. In various embodiments, the uncoiling unit 90 can be configured to automatically feed the panel media 22 into the panel forming unit 10. It is contemplated that the speed at which the panel media 22 is fed into the panel forming unit 10 can vary depending upon various factors that include, but are not limited to, the complexity of the cladding panel 32 to be formed, the type of panel media 22 used, the size of the cladding panel 32, the number of courses 100 to be formed within the cladding panel 32, the number of relief sections 102 to be formed within the courses 100 of the cladding panel 32, among other factors. The uncoiling unit 90 can be one of several units that include a single mandrel unit or a multiple mandrel unit. The uncoiling unit 90 can also include various features such as brake and drive controls, a loop control 82, as well as others features for delivering the rolled panel media 22 to the panel forming unit 10.
Step 506 of the method 500 includes embossing the predetermined texture 30 to be defined within the panel media 22 using the embossing unit 12. As discussed above, the predetermined texture 30 can vary depending upon the desired material and finish that the formed cladding panel 32 is meant to show. The force necessary to include the texture 30 defined within the panel media 22 can depend upon the panel media 22 used. The panel media 22 can include a steel sheet that is disposed in a rolled sheet coil, such as a rolled steel coil, and fed into the panel forming unit 10. Other panel media can include, but are not limited to, vinyl, aluminum, plastic, and other substantially formable materials that can be used as cladding materials. One example of material that can be used as the panel media 22 is G90 pre-galvanized steel, grade 37.
According to step 508, the method 500 also includes pressing guide lines 40 and guide indents 42 into a surface of the panel media 22, using the punch press 14. As discussed above, the guide lines 40 are included to allow for easier bending and forming of the material during formation of the cladding panel 32. Various apertures, such as the drain apertures 50, can also be formed during operation of this step 508. Additionally, the guide indents 42 formed upon the panel media 22 provide attachment guides through which nails, screws, or other fasteners can be used to attach or otherwise fasten the cladding panel 32 to the structure. It is contemplated that the cladding panels 32 formed through this method can be roofing panels, wall panels, interior or exterior panels, as well as panels used in other building applications that can utilize a wide range of fasteners, thereby requiring varying configurations of guide lines 40 and guide indents 42.
According to the method 500, step 510 includes stamping the predetermined relief pattern 70 defined within the panel media 22 using the stamping die 16, such that the predetermined texture 30 is at least partially defined within the relief pattern 70. As discussed above, the predetermined relief pattern 70 can include individual relief sections 102 that can make up courses 100 of the predetermined relief pattern 70. In various embodiments, the relief sections 102 may not form into courses 100 of the cladding panel 32, but rather may form alternate patterns upon the cladding panel 32, that include, but are not limited to, irregular patterns, alternating patterns, diagonal or vertical patterns, and arcuate patterns, among others. These individual relief sections 102 can be defined within the panel media 22 by stamping the shape of the relief sections 102 within the panel media 22. Alternatively, the relief sections 102 can be formed by stamping relief channels 110 that are disposed between the relief sections 102 such that as the relief channels 110 are formed, and the relief sections 102 are extruded between the relief channels 110. It is contemplated that two sets of forms can be used cooperatively to define both the relief sections 102 and the relief channels 110 between adjacent relief sections 102 to form a three-dimensional pattern within the panel media 22.
As illustrated in
According to step 510, as the stamping die 16 is used to form the relief pattern 70 within the panel media 22, the stamping die 16 is configured so as to not substantially press against the predetermined texture 30 that has been defined within the panel media 22 by the embossing unit 12, according to step 506. In this manner, the stamping die 16 can include a rigid form at certain portions that are used to define the edges 124 of the individual relief sections 102 and relief channels 110 within the panel media 22. Areas within these rigid portions of the stamping die 16 may include apertures, softer materials, cushion material or other features that prevent the predetermined texture 30 from being pressed out of the panel media 22 while the predetermined relief pattern 70 is being formed.
According to step 512, the method 500 also includes cutting the panel media 22 into cladding panels 32 having a predetermined length using the shear press 18. As discussed above, the shear press 18 is configured to cut the media panels such that each panel is substantially uniform and includes the guide lines 40 and guide intents in substantially the same location on each of the cladding panels 32. In various embodiments, the guide lines 40 defined within the panel media 22 by the punch press 14 can include a guide line 40 through which the shear press 18 is to cut each individual roofing panel. In such an embodiment, the force necessary to cut through the panel media 22 can be lessened where the material of the panel media 22 has already been weakened through the formation of corresponding guide lines 40 by the punch press 14, according to step 508. It is also contemplated that the shear press 18 can not only cut individual lengths of predetermined cladding panels 32, but also cut predetermined widths of cladding panels 32, wherein horizontal and vertical cutting mechanisms of the shear press 18 can be used to cut out multiple cladding panels 32 within each section of the panel media 22. In various embodiments, where two or more cladding panels 32 are configured to be narrower than a standard width of the panel media 22, multiple cladding panels 32, and/or different types of cladding panels 32 can be formed simultaneously in a side-by-side configuration so as to substantially limit waste of the panel media 22.
According to the method 500, step 514 includes forming at least one flange proximate an outer edge 140 of each of the cladding panels 32 using the roll former 20, wherein the cladding panels 32 each include at least one flange, the predetermined texture 30 and the predetermined relief pattern 70. As shown in
According to step 516, the method 500 can also include collecting or receiving each cladding panel 32 onto an exit conveyor 80 after the cladding panels 32 leave the roll former 20 of the panel forming unit 10. Once on the exit conveyor 80, the individual cladding panels 32 can be sorted based upon various characteristics, evaluated for quality control, sent to other areas or locations for packaging and shipment, among other functions.
Referring now to
Referring now to
It is contemplated that in various embodiments, the first relief pattern can correspond to the individual relief sections 102 and relief channels 110 defined within the cladding panel 32 and the second relief pattern can correspond to the predetermined texture 30 applied to the cladding panel 32. In such an embodiment, the texture 30 applied by the embossing unit 12 to the surface of the rolled panel media 22 is applied after the stamping die 16 has defined the individual relief sections 102 and relief channels 110 within the rolled panel media 22. In this manner, the embossing unit 12 will be required to include a profile substantially similar to that of the relief pattern 70 created by the individual relief panels and relief channels 110 disposed within the rolled panel media 22 in order to properly dispose the texture 30 within the relief sections 102 and relief channels 110.
According to step 712 of the method 700, the patterned media is then cut into cladding panels 32 using a shear press 18, wherein each of the panels is a predetermined length. According to step 714, the cladding panels 32 are formed using the roll former 20 to include at least one flange on an edge of each of the cladding panels 32, such that the cladding panels 32 each include at least one flange, the first relief pattern, and the second relief pattern. After being formed, step 716 of the method includes collecting the cladding panels 32 at an exit conveyor 80 configured to receive each cladding panel 32 after exiting the roll former 20.
It is contemplated that in various embodiments, the steps described herein can be adjusted and performed in alternate orders. By way of explanation, and not limitation, the rolled panel media 22 can be inserted into the cladding panel assembly 10 and immediately cut into individual panels and then formed into the desired panel configuration. In such an embodiment, once the rolled panel media 22 is cut, each piece of rolled panel media 22 can sent to one of a plurality of conveyors 52, wherein each conveyor 52 leads to a cladding panel assembly 10 configured to form different types of cladding panels 32, thereby allowing a number of assemblies to be disposed adjacent or parallel with one another, while allowing multiple panels to be formed, within a single location.
