Description
- This application claims the benefit of U.S. Provisional Application No. 63/384,850, filed on Nov. 23, 2022, which is hereby incorporated by reference, to the extent that it is not conflicting with the present application.
- The invention relates generally to methods and apparatuses for wrapping panels and specifically to methods and apparatuses for automatically rolling and wrapping body panels.
- In the automotive industry, automotive manufactures are often reliant upon imported parts and components in order to acquire the necessary elements to fully assemble their products. Structures such as body panels, including bumpers, may be manufactured offsite and imported in order to save on manufacturing costs or utilize body panels from a preferred manufacturer during vehicle fabrication. However, after being manufactured, completed vehicle body panels may be large and cumbersome, thus having larger dimensions that require large boxes or packages in order to ship to their destination. Larger packages often cost more to ship, thus resulting in hefty shipping costs for transporting completed vehicle body panels, particularly when shipping them internationally. In some instances, the shipping costs associated with shipping a body panel internationally may exceed the price of the body panel itself, adding significant expenditures to the vehicle manufacturing process.
- Therefore, there is a need to solve the problems described above by proving a device and method for efficiently wrapping a body panel to reduce its overall dimensions to minimize packaging volume.
- The aspects or the problems and the associated solutions presented in this section could be or could have been pursued; they are not necessarily approaches that have been previously conceived or pursued. Therefore, unless otherwise indicated, it should not be assumed that any of the approaches presented in this section qualify as prior art merely by virtue of their presence in this section of the application.
- This Summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description.
- In an aspect, a body panel wrapping apparatus is provided, the body panel wrapping apparatus being configured to quickly and automatically wrap a body panel for a vehicle, structure, etc. with minimal or no human interventions. Thus, an advantage is that panels may be wrapped more quickly, efficiently, and with reduced labor costs. Another advantage is the reduced likelihood of body panel damage, as a result of the high level of reproducibility enabled by using an automated device to perform this operation. Another advantage is that the automatic nature of the panel wrapping apparatus allows for wrapping operations to be scaled more easily.
- In another aspect, a body panel wrapping apparatus is provided, the body panel wrapping apparatus having a panel engaging portion configured to engage with a panel and rotate, rolling the panel into a compact package while simultaneously covering said panel with a layer(s) of wrapping. In said aspect, the panel engaging portion may have a moving compression arm and a stationary compression arm, wherein the body panel is configured to be selectively compressing between the moving and stationary compression arms. Thus an advantage is that the overall size of the panel may be reduced, thus allowing for a smaller box or package to be used to package the panel, thus reducing the packaging cost. Another advantage is that the resultant smaller package will also be cheaper to ship, especially internationally, wherein the cost of international shipping contributes greatly to the overhead costs of outfitting a vehicle with panels. Another advantage is that the wrapping may protect not only the outer surface of the wrapped panel, but also the internal surfaces of the wrapped panel that said wrapping is layered between as the panel is rolled, thus reducing the chances of the panel scratching itself as it is rolled or shipped. Another advantage is that if wrapped body panels need to be stored in inventory prior to shipping, the amount of inventory space required may be reduced when compared to storing unwrapped body panels.
- In another aspect, a body panel wrapping apparatus is provided, the body panel wrapping apparatus being configured to be controlled by a programable logic controller, such that the operation of the body panel wrapping apparatus may include automated procedures. Thus, an advantage is that the usage of automation may improve productivity and minimize apparatus down time, and with limited human intervention. Another advantage is that the labor required to wrap body panels may be reduced, thus increasing profitability.
- In another aspect, a body panel wrapping apparatus is provided, the body panel wrapping apparatus have a plurality of control elements, such as rotation controllers and control pedals configured to facilitate operation of its various electrical and pneumatic elements of the body panel wrapping apparatus. Thus an advantage is that the performance of the various necessary operations, such as rotation of the panel engaging portion and movement of the moving compression arm toward and away from the stationary compression arm may be done by a user my simply pressing a button, depressing a pedal, etc., thus making it easier for a singular user to wrap a panel without outside assistance. Each control element may be configured to electrically and/or pneumatically control a corresponding element of the body panel wrapping apparatus, utilizing a pressure and/or electricity source to facilitate fast and easy wrapping of each body panel.
- In another aspect, the body panel wrapping apparatus may further comprise a roll receptacle configured to pivotally engage with and selectively compress/restrict rotation of a wrapping roll. Thus an advantage is that the roll receptacle's engagement with the wrapping roll may apply tension on the wrapping from the wrapping roll as it is applied to the body panel, thus creating a tight wrapping layer around the body panel, protecting it from damage and minimizing its size. The type of wrapping on the wrapping roll may be varied in accordance with the needs of the application, required material strength, etc.

FIGS. 1A-1C illustrate the front, right and left side perspective views, accordingly, of a bodypanel wrapping apparatus 101, according to an aspect. The herein disclosed body panel wrapping apparatus (“panel wrapping apparatus,” “wrapping apparatus”) 101 may be used to quickly and easily wrap a body panel (“panel”), or other suitable structure, while minimizing its packaging volume. The bodypanel wrapping apparatus 101 may be configured to minimize the packaging volume of a body panel, such asbumper 220 ofFIG. 2B , by rolling the body panel into a compact shape as it wraps it for shipping and/or storage. Body panels may be preheated prior to rolling and wrapping to prevent damage to the body panel, increase body panel flexibility and reduce the amount of force required to suitably roll said body panel, as described inFIG. 5 hereinbelow. The compact size of the resultant wrapped body panel may allow it to be placed into a smaller, less cumbersome box, thus reducing the costs associated with transporting it. In an embodiment, the bodypanel wrapping apparatus 101 may be configured to wrap a body panel nearly automatically/autonomously and with minimal human intervention after engagement of the panel with the bodypanel wrapping apparatus 101, as will be described in greater detail hereinbelow. - The body
panel wrapping apparatus 101 may comprise several main components. These main components may include apanel engaging portion 102 configured to engage with and rotate the body panel to enable rolling and wrapping of said body panel. In an embodiment, additional main components may include arotation controller 105, acontrol motor 106, apressure regulator 126, a variablepressure solenoid valve 107 in pneumatic communication with the pressure regulator, 126 and acontrol panel 108. In an embodiment, the bodypanel wrapping apparatus 101 may further comprise an optional loading table 104 configured to support a body panel prior to engagement with the panel engaging portion. It should be understood that each main component may be secured to or otherwise associated with a body frame (“frame”) 109 to ensure suitable interconnection of each component as disclosed herein. Each of these components may be further interconnected through corresponding applicable structures, such as wires, hoses, etc. to enable proper apparatus function as described herein. - The body
panel wrapping apparatus 101 may have apanel engaging portion 102 that is configured to selectively engage with and subsequently rotate a panel, to allow the panel to be rolled and wrapped using a wrapping roll (“shrink wrap roll”) 103 pivotally engaged with thebody frame 109. The rotation of said panel and attachment of a loose end of the wrappingroll 103 to said panel will result in thewrapping roll 103 rotating as the panel rotates. Thepanel engaging portion 102 may be pivotally engaged with, or otherwise associated with thebody frame 109 by virtue of its attachment to a vertical shaft 110 (and its associated connections), and may be disposed above the optional loading table 104. In an embodiment, a body panel may be temporarily supported by the loading table 104 while being engaged with thepanel engaging portion 102 by a user. It should be understood that the loading table 104 associated with thebody frame 109 may not be included in all embodiments. Thepanel engaging portion 102 may have a pair ofcompression arms compression arm 102 a is associated with theplatform 102 c and configured to be moved to selectively sandwich/compress a bumper or other body panel between the movingcompression arm 102 a and astationary compression arm 102 b. This effectively secures the panel between thecompression arms - In an embodiment, the moving
compression arm 102 a may be moved by an attached compression cylinder, such ascompression cylinder 213 ofFIG. 2D , as will be discussed in greater detail hereinbelow. In an embodiment, thepanel engaging portion 102 may be surrounded by perimeter straps, such as perimeter straps 214 ofFIG. 2A , that are configured to ensure that parts of the panel do not protrude beyond the perimeter of thepanel engaging portion 102 as it is being wrapped. These perimeter straps may be secured to support posts, such as support post 109 a, as will be discussed in greater detail hereinbelow. - In an embodiment, the body
panel wrapping apparatus 101 may further comprise an optional loading table 104 that is configured to support a body panel, such as a bumper, before and/or during the wrapping process. This loading table 104 may be slidably associated with thebody frame 109 and disposed below thepanel engaging portion 102 to provide suitable support for panels that are being engaged with the bodypanel wrapping apparatus 101 to be wrapped. The loading table 104 may comprise aloading base 104 a and aloading wall 104 b disposed above and perpendicular to theloading base 104 a. In an embodiment, theloading base 104 a may be used to support the weight of a panel prior to wrapping of said body panel. Theloading wall 104 b may be configured to prevent the body panel from being swung around during the wrapping process, by restricting the movement of any unwrapped portion of the body panel, as will be described in greater detail hereinbelow. Theloading base 104 a or the entirety of the loading table 104 may be configured to slide horizontally, such that it may leave the underside of thepanel engaging portion 102 open to the body frame surface disposed below, thus providing additional vertical clearance below a wrapped body panel and providing a user more space to grab said wrapped body panel after wrapping is completed. - In an embodiment, as can be seen in
FIG. 1C , theloading base 104 a andloading wall 104 b may be slidably engaged with thebody frame 109 by apneumatic rail 104 c. The retraction of the loading table 104 through the utilization of saidpneumatic rail 104 c may happen automatically at the end of the timed wrapping cycle, based upon how the programmable logic controller (“PLC”), such asPLC 429 ofFIG. 4C , is configured. Overall, the timer function that dictates the timing of automated bodypanel wrapping apparatus 101 operations may be controlled by a Human Machine Interface screen (“HMI screen”) 150 used in conjunction with the programable logic controller, wherein the PLC and HMI screen are in electrical communication with each other. The extension of the loading table 104 such that it is directly below thepanel engaging portion 102 may be triggered by a user pressingfoot pedal 111 a before or after a completed wrap cycle. - In an embodiment, the
rotation controller 105 may be a suitable electronic/electrical device that is configured to be in communication with the panel engaging portion 102 (or more specifically in electrical communication with thecontrol motor 106 that manipulates it) in order to facilitate rotation of thepanel engaging portion 102 using thecontrol motor 106. Thisrotation controller 105 may be configured to rotate thepanel engaging portion 102, and thus thecompression rotation controller 105 may be provided with a variety of buttons/dials to allow a user to initiate automated wrapping procedures, and/or allow the user to assume manual control of compression arm rotation, thus allowing the user to start and stop the rotation of the compression arms at will. Therotation controller 105 may be configured to facilitate the wrapping of a body panel through coordination with theaforementioned control motor 106 while the body panel is held. As such, therotation controller 105 and may be in electrical communication with both thepanel engaging portion 102 and thecontrol motor 106. While the body panel wrapping apparatus embodiment ofFIG. 1A-1C may utilize acontrol motor 106 to rotate the panel engaging portion, alternative mechanisms, such as a manual crank mechanism (not shown) may instead be used, as will be described in greater detail hereinbelow. - In an embodiment, the
control motor 106 may be associated with theframe 109 and configured to facilitate the rotation of a body panel engaged with thepanel engaging portion 102 to facilitate wrapping of said body panel. Thecontrol motor 106 may be an A/C inverter duty motor, wherein said motor is configured to couple with agearbox 128. The rotation speed of thecontrol motor 106 may be configured to be controlled by a variable power frequency inverter drive, such as variable powerfrequency inverter drive 435 ofFIG. 4C . Thiscontrol motor 106 may be configured with the proper specifications (e.g., torque) to allow for the rolling of a body panel in a controlled fashion to prevent damage to the body panel during wrapping. As disclosed herein, the body panels may also be preheated in order to increase their flexibility prior to rolling/wrapping, thus reducing the overall torque required to successfully roll and wrap the body panel. As with any conventional motor, saidcontrol motor 106 may be in electrical communication with a power source, such as an electrical outlet, at least indirectly. Thecontrol motor 106 may be attached to thebody frame 109 and disposed above thepanel engaging portion 102, such that avertical drive shaft 110 disposed between and engaged with thecontrol motor 106 and thepanel engaging portion 102 may be configured to spin thepanel engaging portion 102 to facilitate wrapping/rolling of an engaged body panel. The interaction between thecontrol motor 106 and thepanel engaging portion 102 will be discussed in greater detail hereinbelow. - In an embodiment, the
control motor 106 may be an A/C Inverter Duty 5 Hp motor. In said embodiment, thegear box 128 may be a gear box/speed reducer/transmission having a right-angle output with 20:1 reduction ratio. In order to facilitate proper operation of thepanel engaging portion 102, thecontrol motor 106 may be directly coupled to thegear box 128. A chain sprocket (not shown) may be mounted to the output shaft of thegearbox 128. A roller chain (not shown) may be configured to connect the chain sprocket to a secondary sprocket (not shown), wherein the secondary sprocket is mounted to thevertical shaft 110. Thevertical shaft 110 may pass through an upper mounted bearing (not shown) and lower mounted bearing (not shown) such thatvertical shaft 110 engages with thepanel engaging portion 102, or more specifically, the platform of the panel engaging portion, such asplatform 202 c ofFIG. 2D . As such, the platform, and thus by extension, thepanel engaging portion 102 may be pivotally engaged with thebody frame 109. The electrical power provided to the motor for operation may be regulated via a variable power frequency inverter drive, such as variable frequency drive 435 ofFIG. 4C , such that the rotation speed of saidcontrol motor 106 is controlled by variable power frequency inverter drive. - In an embodiment, the variable
pressure solenoid valve 107 may be configured to control the amount of pressure that is applied to theshrink wrap roll 103 to restrict the shrink wrap roll's ability to rotate freely. The resultant pressure exerted on theshrink wrap roll 103 is configured to increase the force required to rotate the wrapping roll (e.g. increase the wrapping roll's resistance to being rotated) to create tension, which helps snuggly wrap the body panel in wrapping from theshrink wrap roll 103 as it is rotated. The tension exerted on theshrink wrap roll 103 may be applied by an air cylinder, such asair cylinder 336 ofFIG. 3 , in pneumatic communication with the variablepressure solenoid valve 107. The variable pressure solenoid valve may vary the air pressure provided to the air cylinder to achieve the desired pressure/tension to optimally wrap a corresponding body panel. In an embodiment, this air cylinder selectively adjusts (e.g., pulls down) a roll top keeper, such as rolltop keeper 337 ofFIG. 3 , onto theshrink wrap roll 103 to restrict the movement/rotation of theshrink wrap roll 103. The amount of pressure and the time interval over which this pressure is applied may be varied at different stages of the wrapping process and may be controlled by the aforementioned PLC, and/or changed by the user/operator as required via the HMI screen. - In an embodiment, the
control panel 108 may act as an electrical hub for all of the electrically powered components of the bodypanel wrapping apparatus 101. As such, in said embodiment, thecontrol panel 108 may be in electrical communication with thecontrol motor 106, therotation controller 105, and the variablepressure solenoid valve 107, as well as an external power source, such as an electrical outlet (not shown) and any other electrically powered elements of the bodypanel wrapping apparatus 101. In an embodiment, thecontrol panel 108 may be in electrical communication with a main power line (not shown) that is configured to engage with a standard 120V power outlet to power thepanel wrapping apparatus 101. Thecontrol panel 108 may contain instrumentation and indicators to provide insight into current device operation. One such indicator may be an indicator light 108 b that is configured to light up during certain parts of wrapping procedures to inform users of wrapping progress, relevant alerts, etc. Thecontrol panel 108 may also have additional ports, buttons, indicators and relevant control devices enclosed within. - The control panel may further comprise: an emergency
stop mushroom pushbutton 108 a that is configured to de-energize the body panel wrapping apparatus and disengage all existing forces and motions of each structure, a fault/condition indicator light 108 b with audible buzzer that is configured to flash and buzz when the emergency stop mushroom pushbutton is pressed (e.g., when theapparatus 101 is in emergency stop mode), a main power indicator light 108 c that is configured to light up when the machine is energized with A/C power, and a mainpower disconnect switch 108 d configured to selectively connect the bodypanel wrapping apparatus 101 to a 220V AC power source. In and embodiment, thecontrol panel 108 may further comprise: a wrapcycle start pushbutton 108 e configured to be pressed to start a timed wrap cycle, a wrapcycle stop pushbutton 108 f configured to be pressed to stop a timed wrap cycle, and amode switch 108 g configured to be pressed to selectively change the machine between an automatic and timed cycle mode for wrapping, and may also be used to selectively retract or extend the loading table 104 as disclosed herein. It should be understood that the buttons, switches and indicators present on the control panel may be varied in accordance with the needs of the application. - In an embodiment, the body
panel wrapping apparatus 101 may be configured to either wrap a body panel automatically by rotating said body panel for a preprogrammed amount of time, or may be controlled manually by a user using the hereinabove disclosed buttons and theHMI control screen 150. As mentioned hereinabove, thecontrol panel 108 may also further comprise anHMI control screen 150 that is configured to display timer control parameters and provide a means for the user/operator to change cycle time and the shrink wrap tension parameters as required, such as tension control buttons (not shown). Each of these control panel elements may be attached to a steelelectrical enclosure 108 h, which may contain additional structures, as will be disclosed hereinbelow. - In an embodiment, in order to suitably supply air pressure to operate the various pneumatic devices of the panel wrapping apparatus disclosed herein, a
main air hose 123 may connect the pressure regulator to anexternal pressure line 127. The pressure regulator may be further connected to (e.g., in pneumatic communication with) each pneumatic device, accordingly (e.g., thepneumatic rail 104 c, thecompression cylinder 213 ofFIG. 2D , theair cylinder 336 ofFIG. 3 , etc.). Themain air hose 123 may be in pneumatic communication with thepressure regulator 126 such that the pressure regulator is configured to manage/regulate the main/master air pressure for all pneumatic devices on thepanel wrapping apparatus 101. The pressure regulator may also be connected to a diverting air manifold or pipe tee which directs pressurized air to the pressure gauge and electrically controlled air solenoid valves, such aspressure gauge 107 a and electrically controlled air solenoid valves (not shown). In an embodiment, thepressure gauge 107 a may be configured to control the tension exerted on the air cylinder, whereas the bank of electrically controlled air solenoid valves may be configured to control thepneumatic rail 104 c and the compression cylinder, such ascompression cylinder 213 ofFIG. 2D . Thepressure gauge 107 a may provide a visual indication of the pressure being exerted on the corresponding elements pneumatically connected to variablepressure solenoid valve 107. In an embodiment, the variablepressure solenoid valve 107 may be a special type of variable output air valve, wherein the variablepressure solenoid valve 107 is configured to receive a preset electrical signal from the PLC at a specific time interval to adjust the output pressure in proportion to the electrical signal being received. In an embodiment, the movement of the movingcompression arm 102 a and the sliding of the loading table 104 may be controlled by corresponding pneumatic devices in pneumatic communication with theexternal pressure line 127. - Each of the elements of the body
panel wrapping apparatus 101 may be configured to attach to thebody frame 109, at least indirectly, for secure attachment to the bodypanel wrapping apparatus 101 and thus each other. Thebody frame 109 may be made of any suitably strong material to support the weight of and suitably interconnect each of the herein described structures of the bodypanel wrapping apparatus 101. In an embodiment, thebody frame 109 may be made of steel or another suitably strong metal that can support and interconnect the body panel wrapping apparatus elements. In said embodiment, thebody frame 109 may comprise a plurality of hollow pipes having a suitable wall thickness to maintain the required strength of thebody frame 109 while minimizing its weight and cost. Each applicable structure of the bodypanel wrapping apparatus 101 may be attached to thebody frame 109 through suitable means, such as welding, screws, nuts and bolts, other suitable fasteners, etc. Aswivel wheel 116 may be attached to eachbase corner 109 b of thebody frame 109 to allow for easy movement of thepanel wrapping apparatus 101. - As mentioned hereinabove, the
panel engaging portion 102 may be associated with thevertical drive shaft 110, such that the rotation of thevertical drive shaft 110 about arotational axis 112 is configured to rotate thepanel engaging portion 102, and thus thecompression arms rotational axis 112. This in turn results in the rolling and wrapping of a body panel compressed between thecompression arms vertical drive shaft 110 to rotate thecompression arms control motor 106 or another suitable device/mechanism, which itself may be actuated by a user through manipulation of the hereinabove disclosedrotation controller 105. In an embodiment, when a wrapping material of the wrappingroll 103 is engaged with a body panel, the rotation of thepanel engaging portion 102 about therotational axis 112 causes rolling of the body panel and wrapping of the body panel with wrapping material from the wrapping roll. - In order to manipulate the moving
compression arm 102 a to facilitate engagement of the panel engaging portion with a suitable body panel, an additional control mechanism, in the form of acontrol pedal 111 a, may be implemented. Manipulation of thiscontrol pedal 111 a may result in actuation of a compression cylinder, such ascompression cylinder 213 ofFIG. 2D , and thus the compression or decompression of thecompression arms control pedal 111 a while the movingcompression arm 102 a is extended away from thestationary compression arm 102 b will result in the moving of thecompression arm 102 a toward thestationary compression arm 102 b. By having acontrol pedal 111 a that a user may control using their foot, the user may have their hands free to manipulate a held body panel into the correct position for compression between thecompression arms panel engaging portion 102 without the assistance of a secondary user. - The
control pedal 111 a may allow a single user to assume control over panel wrapping procedures. Thecontrol pedal 111 a may be in electrical communication with the variable pressure solenoid valve, wherein the variablepressure solenoid valve 107 may be in pneumatic communication with a compression cylinder, such ascompression cylinder 213 ofFIG. 2D , such that manipulation of thecontrol pedal 111 a results in movement of the movingcompression arm 102 a. In an embodiment, the variablepressure solenoid valve 107 may also be in pneumatic communication with thepneumatic rail 104 c, such that manipulation of thecontrol pedal 111 a results in movement of the loading table 104 as well, if applicable. Thecontrol pedal 111 a may be attached to a pedal handle (not shown) to make moving thecontrol pedal 111 a around easier. Anauxiliary pedal 111 b may also be secured to thecontrol pedal 111 a, wherein the auxiliary pedal may be configured to initiate other apparatus operations, as needed. In an embodiment, theauxiliary pedal 111 b may operate as an emergency power cut off, thus allowing a user close to thecontrol pedal 111 a to quickly and safely turn off thepanel wrapping apparatus 101, while remaining sufficiently distant from thepanel engaging portion 102. As is understood, thecontrol pedal 111 a may be in communication with the compression cylinder, such that an electrical signal generated from pressingcontrol pedal 111 a eventually leads to pneumatic operation of the disclosed compression cylinder, as described in greater detail hereinbelow. - It should be noted that each element of the
panel wrapping apparatus 101 may be made of a suitable material to ensure device functionality as disclosed herein. For example, structures designed to support heavier loads, such as thebody frame 109, may be made of more durable, high strength materials, such as metals like aluminum or steel. Structures designed to support moderate amounts of weight, such as the optional loading table may be made out of somewhat strong, but lightweight materials, such as wood or particle board, as the weights of generally lightweight vehicle panels do not typically warrant the use of high strength materials to support them. Each structure of thepanel engaging portions 102 may be made of a high strength material, such as steel, with the exception of the outer portions of thecompression arms - Any controller-based devices (
rotation controller 105,compression pedal 111 a,auxiliary pedal 111 b, etc.) may be made from the proper combination of metal, plastic, electrical components, etc., to allow them to be durable, while suitably performing their intended function (being used to control apparatus elements). Any tubing, wiring or other conventional connective elements may use any of the known flexible connective materials used for their equivalents. The wrappingroll 103 may use any suitable wrapping material (cellophane, shrink wrap, plastic wraps, straps, twine, etc.) that provides suitable strength to securely wrap each panel, as necessary. Any other structures may utilize appropriate materials such as metals, plastics, rubbers, etc. in order to suitably achieve their functions as described herein. -
FIG. 2A illustrates the front view of thepanel engaging portion 202 of the body panel wrapping apparatus, according to an aspect.FIG. 2B illustrates the front-left side perspective view of thepanel engaging portion 202 of the body panel wrapping apparatus, according to an aspect.FIG. 2C illustrates the left side perspective view of thepanel engaging portion 202 of the body panel wrapping apparatus, according to an aspect.FIG. 2D illustrates the top right perspective view of thepanel engaging portion 202 of the body panel wrapping apparatus, according to an aspect. As disclosed hereinabove, in order to allow the body panel wrapping apparatus, such as bodypanel wrapping apparatus 101 ofFIG. 1A , to selectively secure abody panel 220, during wrapping, apanel engaging portion 202 may be employed to clamp around saidbody panel 220. Thepanel engaging portion 202 may compress/sandwich/clamp thebody panel 220 between a pair ofcompression arms body panel 220 prior to rolling/wrapping of saidbody panel 220 using the attached wrappingroll 203. - The
panel engaging portion 202 may comprise aplatform 202 c having a nestedarm travel cutout 202 d, acompression cylinder 213 attached to theplatform 202 c, thecompression cylinder 213 having abase housing 213 a disposed above and attached to theplatform 202 c and atraveling piston 213 b configured to partially nest within thebase housing 213 a, astationary compression arm 202 b attached to or otherwise associated with theplatform 202 c, and a movingcompression arm 202 a attached to thetraveling piston 213 b such that the compression arm is partially disposed within thearm travel cutout 202 d. Thepanel engaging portion 202 may further comprise arotational shaft 210 attached to theplatform 202 c, such that rotation of therotational shaft 210 about arotational axis 212 results in the rotation of thepanel engaging portion 202 about saidrotational axis 212, and thus the wrapping of a body panel secured between thecompression arms - The
vertical shaft 210 may comprise arotational shaft 210 a coupled to an air union, such asair union 410 b ofFIG. 4A , such that air supply hoses may travel through therotational shaft 210 to thecompression cylinder 213, wherein the air union is disposed above therotational shaft 210 a. As such, air supply hoses, such asair supply hoses FIG. 4A , may help provide a pneumatic connection between the variablepressure solenoid valve 207 and thecompression cylinder 213 without being spun or bent by the rotation of therotational shaft 210 andpanel engaging portion 202. The connection between the air union and therotational shaft 210 a may allow pressurized air to travel from the air supply hoses to thecompression cylinder 213. The opposing end of each air supply hose may terminate at the prior disclosed solenoid valve, such as the bank of electrically controlled solenoid valves, to facilitate manipulation of the movingcompression arm 202 a as disclosed herein. As such, the air supply hoses may be included in the outlet of the variablepressure solenoid valve 207. - In an embodiment, the
platform 202 c may have a round shape, wherein theplatform 202 c is configured to be rotated about a centrally disposedrotational axis 212 to rotate the attachedcompression arms arm travel cutout 202 d nested within theplatform 202 c and thecompression cylinder 213 attached to theplatform 202 c may be configured such that the movingcompression arm 202 a may be selectively moved toward thestationary compression arm 202 b, thus allowing an object, such as a body panel, positioned between the movingcompression arm 202 a and thestationary compression arm 202 b to be secured between thecompression arms - In order to ensure that the panel that is being wrapped does not protrude beyond the perimeter of the work area of the
panel engaging portion 202, a plurality of perimeter straps 214 may be employed around the perimeter of thepanel engaging portion 202. These perimeter straps 214 may help to avoid the panels being wrapped from protruding outward and colliding with adjacent structures, such as variablepressure solenoid valve 207. These perimeter straps 214 may be secured to afirst support post 209 a-1 and athird support post 209 a-3 and may travel around thesecond support post 209 a-2, thus creating V-shaped perimeter barrier, as seen inFIG. 2A , wherein thesupport posts 209 a-1, 209 a-2, 209 a-3 extend vertically upward from the below portions of thebody frame 209. These perimeter straps 214 may be made out of a somewhat elastic material, such as rubber, in order to allow them to respond flexibly to impacts from body panels without being damaged or damaging a panel. - It should be understood that more or fewer perimeter straps 214 may be utilized in order to provide an optimized enclosure around the panels as they are being wrapped, protecting them from damage while still making them easy to access and manipulate as needed.

In order to allow a user to suitably operate the bodypanel wrapping apparatus 401 to initiate panel wrapping, a plurality of controller devices may be provided for said user to manipulate. One such controller device may be theaforementioned rotation controller 405 disposed above thepanel engaging portion 402 and adjacent to thecontrol motor 406, as seen inFIG. 4A . - The rotation controller may have a plurality of
control elements panel wrapping apparatus 401. In an embodiment, these control elements may include astart button 405 a to initiatepanel engaging portion 402 rotation, astop button 405 b to stoppanel engaging portion 402 rotation, adirectional dial 405 c configured to allow a user to change the rotation directions of thepanel engaging portion 402 rotation (clockwise/counterclockwise) and anemergency stop button 405 d to stop all device operations immediately. It should be understood that different quantities/functions of buttons/dials/etc. may be provided on therotation controller 405 based upon the type of panels being wrapped and their specific needs, as applicable - In order to facilitate engagement between the
control motor 406 and the vertical shaft 410 and thus rotation of thepanel engaging portion 402, amotor drive box 424 may be utilized. Thismotor drive box 424 may be covered by aprotective steel case 424 a and may be configured to allow the rotation of thecontrol motor 406 to rotate therotational shaft 410 a about therotational axis 412 of thepanel engaging portion 402, through conventional drive mechanism techniques and components, such as gears, shafts, etc. Thismotor drive box 424 may be attached to thebody frame 409, disposed above thepanel engaging portion 402, below thecontrol motor 406 and adjacent to therotation controller 405. - As described hereinabove, in order to facilitate proper operation of the
panel engaging portion 402, thecontrol motor 406 may be directly engaged with/coupled to agear box 428. A chain sprocket (not shown) may be mounted to an output shaft of thegearbox 428. A roller chain (not shown) may be configured to connect the chain sprocket to the secondary sprocket (not shown), wherein the secondary sprocket is mounted to the vertical shaft. The vertical shaft may pass through an upper mounted bearing and a lower mounted bearing such that it engages with thepanel engaging portion 402, or more specifically, the platform of the panel engaging portion, such asplatform 202 c ofFIG. 2D . Again, the electrical power provided to thecontrol motor 406 for operation may be regulated via a variable powerfrequency inverter drive 435. As disclosed hereinabove, both thePLC 429 and the powerfrequency inverter drive 435 may be nested within thecontrol panel 408, whereas theHMI 450 may be disposed on an external surface of thecontrol panel 408 for easy access - As disclosed hereinabove, the vertical shaft 410 may comprise a

In an embodiment, a firstair supply hose 425 a may be configured to provide pressurized air to the compression cylinder to extend the moving compression arm away from the stationary compression arm to release a panel held between the compression arms. In the same embodiment, a secondair supply hose 425 b may be configured to provide pressurized air to the compression cylinder to retract the moving compression arm to compress a panel between the compression arms. It should be understood that such arotation controller 405 andcontrol motor 406 may not be required in all embodiments, such as embodiments that may utilize manual rotation by a user to rotate the engaged panel (e.g., a manual crank mechanism). - In an alternative embodiment, the
rotation controller 405 andcontrol motor 406 may be replaced by a manual crank mechanism (not shown), such that the rotation of the panel engaging portion may be done by a user by hand. The utilization of a manual crank mechanism instead of a control motor may reduce the overall complexity and cost to operate the corresponding body panel wrapping apparatus, but may reduce the amount of automation enabled by said body panel wrapping apparatus. In an embodiment, utilizing a manual crank mechanism instead of a control motor/rotation controller, after compressing the body panel between the compression arms of thepanel engaging portion 402, the user may rotate the manual cranking mechanism by hand to rotate the panel engaging portion and the attached body panel, wrapping the body panel in the attached wrapping as it rotates. Once the body panel is sufficiently wrapped, the user may simply stop operating the manual crank mechanism, and proceed with the removal of the wrapped body panel from thepanel engaging portion 402 of the body panel wrapping apparatus. -
FIGS. 5-10 illustrate the method of using the disclosed panel wrapping apparatus to wrap a bumper, according to several aspects.FIG. 5 illustrates the front perspective view of abumper 520 being pre-heated in apanel oven 540, according to an aspect. In the present embodiments ofFIGS. 5-10 , the body panel being wrapped by the panel wrapping apparatus is abumper 520, but it should be understood that any other suitable body panel may also be wrapped using the procedure outlined herein. In order to increase the flexibility of abumper 520 or other body panel during packaging, saidbumper 520 may be heated by placing it within apanel oven 540 at a set temperature for a set amount of time. By increasing the flexibility of a bumper or other body panel prior to wrapping, a tighter, more compact package may be formed without damaging thebumper 520 or body panel, thus increasing packing efficiency and reducing the resultant package size. Apanel oven 540 or similar heating structure may be ideal for heating thebody panel 520, as a result of saidpanel oven 540 providing a uniform heat distribution to thebumper 520, thus ensuring no portion of the bumper becomes significantly hotter than any other. In an alternative embodiment, other sources of heating may be utilized to increase the flexibility of thebumper 520 or other body panel during wrapping, including heating guns or fans, direct sunlight, etc. Following the pre-heating of thebumper 520, saidbumper 520 may be engaged with the body panel wrapping apparatus to begin being rolled. -
FIG. 6 illustrates a front perspective view of auser 621 inserting anend portion 620 a of thebumper 620 between thecompression arms panel engaging portion 602 of the body panel wrapping apparatus, according to an aspect. As can be seen inFIG. 6 , auser 621 may continue the wrapping process by lifting abumper 620 to engage with thepanel engaging portion 602 of the body panel wrapping apparatus. The user may tie or otherwise attach thewrapping material 603 a of the wrappingroll 603 to thebumper 620, to allow thebumper 620 to be wrapped as thebumper 620 is rotated by thepanel engaging portion 602. Prior to engagement with thebumper 620, the movingcompression arm 602 a and thestationary compression arm 602 b are not compressed together, such that thepanel engaging portion 602 is in a relaxed state. As can be seen inFIG. 6 , theuser 621 may manipulate various control elements on the body panel wrapping apparatus to begin operation of the body panel wrapping apparatus, and thus facilitating efficient wrapping thebumper 620. - With the
bumper 620 lifted to engage with thepanel engaging portion 602, theuser 621 may move thebumper 620 such that anend portion 620 a of thebumper 620 is disposed between thecompression arms end portion 620 a of thebumper 620 between thecompression arms user 621 may step on thecompression pedal 611 a to actuate the aforementioned compression cylinder, such ascompression cylinder 213 ofFIG. 2D , and thus actuate the movingcompression arm 602 a to move the movingcompression arm 602 a toward thestationary compression arm 602 b, thus sandwiching/compressing theend portion 620 a of thebumper 620 between thecompression arms platform 602 c. This effectively secures thebumper 620 to thepanel engaging portion 602, thus allowing for the rotation of theplatform 602 c to spin thepanel engaging portion 602, thus rolling thebumper 620, and also wrapping saidbumper 620 as a result of the attachment of thebumper 620 to thewrapping roll 603. - Once the
panel engaging portion 602 is compressed between thecompression arms user 621 may press the appropriate button on the rotation controller, such asrotation controller 405 ofFIG. 4A , to begin rotation of thepanel engaging portion 602. As described hereinabove, this rotation of the panel engaging portion is configured to roll thebumper 620 while simultaneously covering thebumper 620 in layers of wrapping material from the wrappingroll 603. With the initiation of the rotation of thepanel engaging portion 602, potentially through the manipulation of a rotation controller, such asrotation controller 405 ofFIG. 4A , theuser 621 may step back and allow the panel wrapping apparatus to proceed through an automated portion of the panel wrapping procedure. It should be understood that the wrappingroll 603 may rotate as the bodypanel engaging portion 602 begins to rotate, as a result of the attachment of a loose end of the wrappingmaterial 603 a of the wrappingroll 603 to thebumper 620. -
FIG. 7 illustrates a front perspective view of thepanel engaging portion 702 being rotated to continually roll and wrap thebumper 720, according to an aspect. As described hereinabove, after thebumper 720 is engaged with thepanel engaging portion 702 and the wrappingroll 703, thebumper 720 may be gradually rolled and wrapped into a compact package for easy shipping and storage. In an embodiment, while thebumper 720 is being rolled, a loading wall portion of the optional loading table, such asloading wall 104 b ofFIG. 1A , may help to provide a surface that prevents the currently unrolled portion of thebumper 720 from swinging around during wrapping. It should be understood that the support posts of the panel engaging portion, particularly the support post disposed on the same side of the body frame as the loading wall (e.g., thethird support post 209 a-3 ofFIG. 2A ), may also help to prevent thebumper 720 from swinging around unexpectedly during the rolling and wrapping process. -
FIG. 8 illustrates a front perspective view of the rolledbumper 820 being continually rotated to provide additional layers of wrapping around thebumper 820, according to an aspect. After thebumper 820 has been completely rolled into a compact package, it may be rotated for several additional revolutions to provide additional layers of wrapping around it. These additional layers of wrapping may help protect thebumper 820 and keep it from breaking through the packaging during travel, temperature changes, etc. After providing a certain amount of additional wrapping layers around thebumper 820, the movingcompression arm 802 a may be moved away from thestationary compression arm 802 b automatically to allow for easier removal of thebumper 820 from thecompression arms bumper 820 no longer being compressed between thecompression arms platform 802 c, afterpanel engaging portion 802 is returned to the relaxed position, saidbumper 820 may remain attached to thecompression arms material 803 a forcing the bumper to maintain a certain shape and size that remains engaged with the outer surfaces of thecompression arms -
FIG. 9 illustrates a front perspective view of thecompression arms bumper 920, according to an aspect. After the bumper has been fully wrapped, the movingcompression arm 902 a may be further adjusted to loosen the grip of thepanel engaging portion 902 on the wrappedbumper 920 in preparation for removal of the wrappedbumper 920 from thepanel wrapping apparatus 901. As disclosed hereinabove, acompression cylinder 913 attached to theplatform 902 c of thepanel engaging portion 902 may be configured to facilitate adjustment of the movingcompression arm 902 a to loosen the grip of the panel engaging portion with the wrappedbumper 920. In an embodiment, the friction between thecompression arms platform 902 c and thebumper 920 while thecompression arms bumper 920 may be sufficient for thebumper 920 to remain attached to thepanel engaging portion 902, until the user attempts to remove it from thepanel engaging portion 902. - In an embodiment, as the final layers of wrapping are being applied to the
bumper 920, a loading table 904 may be slidably removed from its disposition directly below thepanel engaging portion 902, and thus the wrappedbumper 920. By leaving the space below the now wrappedbumper 920 open, the user may easily place a cart, package or other suitable object directly below the wrappedbumper 920 for transport, storage, etc. In an embodiment, the loading table 904 may be moved automatically without user intervention, as a result of the programming of the body panel wrapping apparatus. - Upon performing a certain number of revolutions of the
panel engaging portion 902 to achieve a desired thickness of wrappingmaterial 903 a around the outside of thebumper 920, the rotation of thepanel engaging portion 902 may be stopped, either automatically as an aspect of system programming or manually at the discretion of the user. After stopping rotation, the user may cut/break the appropriate portion of the attached wrappingroll 903 to disconnect or otherwise disengage the wrappedbumper 920 from the wrappingroll 903. With thebumper 920 fully wrapped and disconnected from the wrappingroll 903, thebumper 920 may be removed from the panel wrapping apparatus by removing the wrappedbumper 920 from thepanel engaging portion 902. In an embodiment, removal of the wrappedbumper 920 may be done by simply adjusting the movingcompression arm 902 a until the wrappedbumper 920 is loose enough to drop off naturally. In an alternative embodiment, removal of the wrappedbumper 920 may be done by adjusting the movingcompression arm 902 a until the wrappedbumper 920 is loose enough for a user to manually pull the wrappedbumper 920 off, thus ensuring a controlled release of the wrappedbumper 920 from the panel engaging portion. -
FIG. 10 illustrates the top perspective view of a wrappedbumper 1020 placed within abox 1042 for shipping, according to an aspect. Upon the completion of the wrapping procedure steps outlined inFIGS. 5-9 , the user may have abody panel 1020 encased in layers of wrappingmaterial 1003 a. As disclosed hereinabove, thiswrapping material 1003 a may be plastic wrap, shrink wrap, straps, twine, or any other suitable material configured to reversibly wrap thebody panel 1020 into a small form factor without damaging it. By wrapping abody panel 1020 though folding, rolling, bending, as disclosed hereinabove, one or more of the dimensions of thebody panel 1020 may be significantly reduced. In an embodiment, a body panel, such as abumper 1020, having a length significantly greater than its width or height may be rolled in a smaller, cylindrical shape, thus significantly reducing its larger “length” dimension. While in this cylindrical shape, as shown inFIG. 10 , thebumper 1020 may be easily fit into asmall box 1042 having dimensions that do not result in increased shipping costs (e.g. within regulation sizes for standard packages). - In short, the wrapping process articulated in
FIG. 5-10 may be summarized as comprising the following steps: obtaining a body panel, such as a bumper, attaching the body panel to the wrapping roll and moving it between the compression arms of the panel engaging portion, actuating the moving compression arm to selectively compress the body panel between the moving compression arm and the stationary compression arm, engaging the body panel with a wrapping roll, initiating rotation of the panel engaging portion, and thus rolling and wrapping the engaged body panel, continuing rolling the body panel until it is fully wrapped within wrapping from the wrapping roll, cutting, or otherwise disengaging the wrapping roll, such that the wrapped bumper is no longer attached to the wrapping roll, removing the body panel from the panel engaging portion, and, optionally, placing the wrapped bumper into a box for shipping. - This wrapping process articulated herein may be modified in light of the alternative embodiments detailed herein, as well as those that would be obvious in light of the disclosure (allowing for additional rotations of the panel engaging portion to achieve a thicker outer wrapping, further manipulating the compression arms to ease removal of the wrapped panel, etc.). Furthermore, each of the above steps may be modified to include additional details regarding the specific structures and elements used to perform each step (e.g., stepping on a compression pedal to actuate the movement of the moving compression arm toward the stationary compression arm to compress/sandwich the panel within the panel engaging portion, etc.) Additional steps prior to placing a body panel on the loading table to prepare said body panel for wrapping, such as preheating the body panel, as seen in
FIG. 5 , may also be utilized to make the body panel more flexible. - By following the steps articulated in
FIG. 5-10 sequentially, a user may singlehandedly wrap a body panel, such as a bumper, into a compact package, quickly and efficiently. As described hereinabove, this wrappedbumper 1020 may be further packaged within conventional storage/transit containers to further protect it from damage, as necessary. As disclosed hereinabove, while the embodiments ofFIG. 5-10 may only show a bumper being wrapped, other panels, such as vehicle side panels, may also be wrapped by following the same procedure. This wrapping procedure may be advantageous for a plurality of reasons, including decreasing shipping costs for transporting the resultant rolled parts (due to decreased object dimensions), particularly for international/overseas shipping, increasing panel wrapping efficiency/decreasing panel wrapping time requirements and decreasing labor demands, amongst other advantages. -
