1. Technical Field The present invention relates generally to the field of manufacturing machines. More particularly, the present invention relates to banner making machines. Specifically, the present invention relates to a banner making machine that welds a strip of reinforcing material to a banner and rivets a grommet through the reinforcing strip and the banner.
1. Background Information
Banners with printed information thereon are a useful way of conveying ideas or announcements to the public. Other banners may have promotional or advertisement material printed thereon. Often these types of banners are displayed outside and are therefore exposed to natural elements such as heat, cold, rain, and wind. When banners hang in the wind from a cord, there is a tendency for the banners to rip or tear at the connection point, usually a grommet, due to wind forces exerted on the banner and grommet. To overcome the stress forces exerted on the banner, some banners are constructed with a reinforcing strip of material extending from end to end near a side edge of the banner, preferably on the back side of the banner so as to not interfere with the printed display information.
Currently, the state of the art includes banner welding machines that have the ability to weld a strip a reinforcing material to a web of banner material. Additionally, the state of the art also includes riveting machines that are able to fire a grommet through a banner having a reinforcement strip welded thereto. These two separate and distinct machines mentioned above are often large, and require production downtime when transferring the banner from one machine to the other.
Issues continue to exist with banner welding machines and banner riveting machines as understood in the prior art. Namely, there exists a need to streamline the banner making process for producing a banner that includes a reinforcing strip welded thereto and grommets riveted through the banner and the reinforcement strip. The present invention addresses these and other issues.
In one aspect, the invention may provide a banner making machine comprising: a banner material flowstream pathway, including first and second sides of the pathway; a machine entrance positioned upstream from a machine exit; a first strip welder between the entrance and exit adapted to weld a strip of reinforcing material to a web of banner material; and a first grommet riveter between the entrance and exit positioned downstream from the first strip welder adapted to rivet a grommet through the reinforcing material welded to the banner material creating a completed banner.
In another aspect, the invention may provide a method for making a banner comprising the steps of: feeding a banner into an entrance of a self-contained banner making machine including an exit downstream from the entrance defining a banner flowstream pathway therebetween; welding a strip of reinforcement material to the banner between the entrance and exit with a strip welder, the strip welder defining a portion of the pathway; and riveting a grommet through the banner and strip welded together between the entrance and exit with a grommet riveter, the riveter defining a portion of the pathway.
In another aspect, the invention may provide a system for making a banner having reinforced edges and grommets comprising: a self-contained banner making machine including a welding device and a grommet riveting device within the machine; a sheet of banner webbing material for feeding through the banner making machine; a strip of reinforcement material that is welded to the banner by the welding device in the banner making machine; and a grommet that is riveted through the banner material with the strip of reinforcement material welded thereto by the riveting device.
In another aspect, the invention may provide a system for making a banner having reinforced edges and grommets includes a self-contained banner making machine including a welding device and a grommet riveting device within the machine. A sheet of banner webbing material is configured to be fed through the banner making machine. A strip of reinforcement material is welded to the banner by the welding device in the banner making machine. A grommet is riveted through the banner material with the strip of reinforcement material welded thereto by the riveting device. The banner making machine includes a banner material flowstream pathway, including first and second sides of the pathway. The welding device or a first strip welder is between the entrance and exit of the machine. The riveting device or a first grommet riveter is also between the entrance and exit positioned downstream from the first strip welder.

Prior to further discussion relating to banner making machine 10, it should be noted that some components of banner making machine 10 are duplicated on respective sides 14, 16 of machine 10. For clarity and purposes of this explanation, some components in some figures are not shown, however it is to be understood by the reader that the components can be duplicated on respective sides 14, 16 as will be explained in further detail below.
As depicted in
Clamp assembly 34 includes an upper clamp 44 and a lower clamp 46. Upper clamp 44 is positioned above lower clamp 46 when viewed from the side, defining a passageway therebetween. Upper and lower clamps 44, 46 are operatively connected. Each upper and lower clamp may be selectively movable in the vertical direction to decrease the gap distance, clamping an object therein as desired by user. In one embodiment, clamp assembly 34 further includes an actuator or motor 48 to mechanically close upper and lower clamps 44, 46. Clamp assembly 34 further includes a trolley assembly 47 to slide on tracks 49. Upper clamp 44 and lower clamp 46 are operatively connected to trolley 47 such they are longitudinally moveable in the direction of pathway 12 along track 49. In one embodiment, motor 48 that actuates the closing of upper clamp 44 and lower clamp 46 may also operate the longitudinal movement of trolley assembly 47 carrying clamps 44, 46. Track 49 is generally parallel with the flow direction of pathway 12. The upstream end of track 49 is generally forward of rear edge 50 of table 52 and the downstream end of track 49 is downstream from a forward end of the drive system 40. As shown in
Table 52 defines an aperture 54, extending generally transverse relative to pathway 12. A first square sensor 56 is positioned underneath aperture 54, configured to sense and view substrate (e.g. banner 26) existing above aperture 54. Sensor 56 is positioned upstream relative to clamp assembly 34. Table 52 further includes a vertically extending lip 58 disposed longitudinally aligned with pathway 12. A rear edge of lip 58 terminates forwardly of rear edge 50 and defines a portion of a notch cutout area retaining a portion of clamp assembly 34 therein. The vertical portion of lip 48 is perpendicular to table 52. Additionally, the longitudinal length of lip 58 is perpendicular to an edge of table 52 defining a square relationship therebetween.
Feeder assembly 36 includes a reel 60 about which reinforcing strip 24 is wound, a feeder motor 62, a sensor 64, a support plate 66, and a cutter 68. Reel 60 is a generally cylindrical member coupled with carriage 42 via support arm 61. Reinforcing strip 24 wound about reel 26 is aligned with and extends through motor 62. Motor 62 is configured to drive strip 24 in an unwinding manner from reel 60, up and over support plate 66 and towards pinch rollers 38. Sensor 64 senses when strip 24 needs to be cut, sending a signal to cutter 68 to cut the reinforcing strip 24 to a desired length. A sensor 63 may also be coupled with feeder assembly 36 configured to sense the amount of wound reinforcing strip material 24 contained on reel 60. As reel 60 unwinds and the amount of reinforcing material 24 is unwound, sensor 63 may send a signal to a control system that alerts an operator that the reel is running low on material 24 and may need replaced. While the shown embodiment indicates sensor 63 and sensor 64 as separate and distinct, clearly it is understood that these two sensors 63, 64 may be combined in a single sensor as one having ordinary skill in the art would understand.
Pinch rollers 38 include an upper roller 70 positioned above a lower roller 72. Upper pinch roller 70 is operatively coupled to a first drive motor 74A (
Drive system 40 includes a drive motor 76, a slip union 78, an axle 80, a drive wheel 82, a plurality of tensioners 84, a lower drive belt 86, and an upper drive belt 88. Lower drive belt 86 rotates around a front roller 90 and a rear roller 92. Upper belt 88 rotates about front roller 94 and a rear roller 96. Front roller 94 is positioned above lower front roller 90 and rear roller 96 is positioned above rear roller 92. In one exemplary embodiment, upper belt 88 is an idle belt only driven by frictional contact movement of lower belt 86 as lower belt 86 is driven by motor 76. Clearly, other embodiments are entirely possible which would include upper belt 88 driven by a motor in a conventionally understood manner. Similar to other components previously described, drive belts 86, 88 extend along each side 14, 16 of pathway 12. In one particular embodiment, a single drive motor 76 drives both sets of belts 86, 88 on each respective side 14, 16 of pathway 12. Axle 80 extends transversely across pathway 12 and drive rollers 82 are coupled to axle 80 adjacent each side 14, 16 of pathway 12.
Slip union 78 enables the single motor 76 to drive belts 86, 88 on each respective side 14, 16 of pathway 12 simultaneously. Further, slip union 78 enables slight adjustments of speed of the belts 86, 88 should they become out of sync with the speed of the other belts operating on an opposite side pathway 12.
Carriage assembly 42 is configured to carry components of banner making machine 10 that are positioned along left side 16 (
With continued reference to
Grommet riveter 28 includes an upper grommet bin 116, an upper sensor 117, a lower sensor 119, and a lower grommet unit 118 configured to fire (i.e., rivet) two halves of a grommet together, riveting them through a piece of reinforcing strip 24 welded to banner 26. Grommet riveter 28 is positioned downstream from a support plate table segment 114B and upstream from a support plate table segment 114G. Grommet riveter 28 is positioned downstream from welder 22 and upstream from exit 20.
As depicted in
Clamp assembly 34 further includes a first upper clamp 44A, a second upper clamp 44B, and a third upper clamp 44C. Upper clamp 44A is closely adjacent first side 14 and is configured to clamp banner material 26 adjacent first side of banner 132. Third upper clamp 44C is closely adjacent second side 16 of pathway 12 as configured to clamp adjacent second edge 134 of banner material 26. In one embodiment, second clamp 44B clamps adjacent the center of banner material 26. However, as depicted in

Prior to description of the operation of the present invention 10, non-limiting aspects and advantages of the present invention 10 are described. The self-contained banner making machine 10 welds a reinforcing strip 24 to a banner material 26 and then rivets grommets to manufacture a completed banner 32 in a single machine 10. The banner making machine 10 allows transverse movement of one side (16) of the device relative to the banner pathway 12 so as to make machine 10 adjustable to finish banners of varying widths. The banner making machine 10 further includes a plurality of sensors for indexing the banner material 26 as it moves along the pathway through the belt drive system 40. Further, the belt drive system 40 is controlled by a single motor 76 utilizing a slip union 78 coupled to an axle 80, thereby allowing the drive belts on each respective side 14, 16 of machine 10 to travel at different rates if needed. One non-limiting example would be a scenario in which the banner 26 traveling downstream was not square and one drive belt needed to be sped up to square off the movement of the banner material moving downstream.

Computer control system 136 includes sensor indexing logic configured to move at least one sensor 56 within the aperture 54 to determine, amongst other things, the width of the banner, as well as whether or not the banner is square with the pathway 12. The sensor indexing logic may further control the other sensors 120, 122, and 124 or they may be independently controlled under their own sensor indexing logic.

Control system 136 may include a banner positioning logic to determine the speed as well as relative square position of the banner 26 as it moves along the pathway 12. Banner positioning logic may also include an instruction sequence sent to feeder assembly 36 to begin unwinding reinforcing strip 24 from reel 60 at a rate similar to that of banner flow such that reinforcing strip 24 and banner material 26 meet at pinch rollers 38 for joining.
In operation, and with reference to
Weld plate 112 is heated by heater 108 via heat transfer member 110 to a temperature hot enough to impart heat into the banner and strip to fuse the banner 26 and the strip of reinforcing material 24 together. The heat of wedge 112 is transferred to strip 24 as the strip 24 passes beneath wedge 112 atop plate 66. The heat from wedge 112 transfers to banner material 26 as banner material flows over the gap defined between support plate 114A and support plate 114B. The strip of reinforcing material 24 and banner material 26 meet and are joined together at the pinch rollers 38. More specifically, banner 26 and reinforcing strip 24 are pinched together between upper roller 70 and lower roller 72. Upper roller 70 rotates in the direction of rotational arrow 150 and lower roller 72 rotates in the direction of rotational arrow 152 opposite that of arrow 150. When joined as a union and welded together, the leading edge 130 of banner 26 is directly above leading edge 154 of strip of reinforcing material 24. The two leading edges 130, 154, continue moving downstream along the pathway 12 in the direction of arrow 142 and a strip of reinforcing material 24 is continuously welded to banner 26 as reinforcing strip 24 continues to flow upwardly in the direction of arrow 148 and heated by wedge 112 just before moving through pinch rollers 38 and being joined with banner 26. It should be noted that while the welding of reinforcing strip 24 to banner 26 occurs outside the belt drives 86, 88, clearly other physical locations relative to sides 14, 16 are entirely possible. In the shown embodiment, both belts 86, 88 are inside relative to the linear center line along pathway 12 relative to welder 22,

Machine 10 is contemplated as operating in three different modes. However, clearly other modes are entirely possible. A first mode utilizes predetermined banner sizes, a second mode is a manual mode, and a third mode is a feed mode. With reference to the first mode, the banner 26 is placed onto the table 52 and may be scanned for a barcode printed on the banner material 26. The barcode is encoded with digital information indicating a plurality of descriptive features of the banner such as size, grommet locations, and length of reinforcing material to be applied. When the banner 26 is on the table, a plurality of lights on the computer may relay information to the operator regarding the status of machine 10. A green light may indicate that the machine is ready for use; a yellow light may indicate that the machine is not ready. After scanning the barcode, the machine determines whether the banner 26 is in a correct orientation, such as the printed side up, or that the correct size and settings are to be applied. In one exemplary embodiment, the operator may select, via the computer, desired settings for the banner such as indoor/outdoor settings. Additionally, another exemplary embodiment allows for the operator to select a pre-determined banner size in the event no barcode is present where the banner sizes may range from small, to medium, to large, and to extra-large. With the banner 26 on the table 52, the operator aligns the banner 26 to the lip edge 58 and the sensor 56 determines if the banner is square while simultaneously determining the width of the banner in order to move the carriage 42 to a complimentary width such that a reinforcing strip is applied on each longitudinal side of the banners bottom surface as it moves down the pathway. When the sensor determines that the banner is square, the clamp will close to secure the banner in the clamping device. The operator may then push the start button to begin the process of banner making machine 10. The transport drive system 40 then grasps the leading edge of the banner via belts 86, 88 and moves it downstream along the pathway. The banner 26 continues to move downstream towards the pair of pinch rollers 38 and, as the banner moves through the pinch rollers, the strip of reinforcing material 24 is moved towards the pinch rollers 38 simultaneously. The banner 26 and the reinforcing strip 24 are heated by the welder 22 just upstream from the pinch rollers 38 such that when the banner 26 and the reinforcing strip 24 meet and travel through the pinch rollers 38, they are sufficiently heated creating a weld as pressure is applied as the two pieces are joined moving through the pinch rollers. The leading edge 130 of the banner 26, now having a strip of reinforcing material 24 welded thereto, now travels towards the grommet riveter 28 which fires a grommet 30 adjacent the leading edge 130 of the banner. Sensors along the pathway sense the trailing edge of the banner which communicates with the cutter 68 to trim the strip of reinforcing material to a length equal to that of the banner. The remaining portion of the banner is welded with a reinforcing strip until the trailing edge of the banner exits the pinch rollers and moves towards the grommet riveter where the grommet riveter fires a grommet through the banner and the reinforcing strip adjacent the trailing edge 170. The banner, having a reinforcing strip welded thereto and a grommet attached there through, now travels via the drive assembly towards the exit of the machine. While this description was made with reference to the general flow of the banner, it is to be understood that this process occurs on each side of the pathway such that a strip of reinforcing material is on each side of the completed banner.
With reference to the second mode of operating machine 10, the operator may set machine 10 to operate in a manual mode. When operating in a manual mode, each side 12, 14 of machine 10 are independently operable from each other. Components of machine 10 operating along first side 14 may form a weld and rivet grommets 30 to the banner 26 at separate intervals and even slightly different speeds if so desired by the operator. In this second mode, an operator places a sheet of banner material 26 onto the table 52 and aligns the banner 26 in a square position with the lip 58. The operator then selectively determines desired output features of the banner through input with the computer. The operator may select whether corner grommets are desired, the temperature of the heater, and whether the left and right sides of machine 10 will operate independently or in unison. When these options are selected, a green indicator light will indicate that the machine is ready for use. After the operator actuates a start button, the clamps secure the banner and travel towards the belt drive system with the banner secured therein. The clamp then opens and the banner is driven downstream along the pathway by belt drive system 40 on each side of the banner. The leading edge sensor senses the leading edge in order to fire a grommet adjacent to the leading edge corners, if that setting is manually input by the user. The leading edge 130 then travels through the welding pinch rollers 38 where it meets and is welded with a strip of reinforcing material 24 that has been heated by the welder 22. As the heated strip of reinforcing material 24 and the heated banner 26 pass through the pinch rollers 38, they are welded, or fused, together and are subjected to pressure by the upper and lower rollers 70, 72. The leading edge 130, now having a strip of reinforcing material 24 welded thereto, proceeds forwards to the grommet riveter 28 where the sensors sense the leading edge in order to rivet a grommet near the corner of the banner. Looking now to the trailing edge of the banner, a sensor senses the trailing edge 170 and determines the length of reinforcing material 24 that needs to be cut via cutter 68 such that it is of a complimentary length of the banner material. The strip of reinforcing material and the banner material continue downstream until a continuous weld is formed from the leading edge down to the trailing edge between the banner material and the strip of reinforcing material.
With reference to the third mode of operation of machine 10, the operator may set machine 10 to a feed mode. The feed mode should run at maximum speed for machine 10. When banner 26 is placed upon table 52, a green light on computer control system 136 will indicate whether or not machine 10 is square. The feed mode includes a timer that determines and sets a length of time that banner 26 will be clamped in the clamp assembly. It should be noted that when machine 10 is in the feed mode, the carriage assembly should be at its maximum width. An operator then actuates a physical start button which turns off a green light that indicated the machine was ready for operation. The actuation of the start button initiates movement of the drive assembly and the welding rollers. The clamp assembly then carries banner 26 into contact with the drive assembly and drive belts 86, 88 which then pull banner 26 downstream in a manner similar to that described above.
