With the inventive conveyor, the increased maintenance requirements due to the presence of idler rolls are minimized or eliminated. In addition, elimination of the idler rolls also results in fabrication of a simpler structure. With a simpler structure to fabricate, the overall system takes less time to erect in a field installation, thereby contributing to reduced capital costs. Further, the absence of the idler rolls results in the elimination of the alignment procedures which must be utilized in prior art conveyor systems.The inventive conveyor is safer than prior art systems through the elimination of pinch points which are present in conveyor systems using idler rolls. With this safety improvement, it may also be possible to eliminate pull cord switches along the conveyor, thus contributing another economic advantage.Operating costs are improved with the inventive conveyor since less power is needed to drive the conveyor belt. In conveyor systems using idler rolls, their mass and friction component contribute greatly to the conveyor power consumption. Through the elimination of idler rolls, the overall conveyor drive force power is reduced, even with the existence of a blower or the like to supply the air for conveyor belt support.The conveyor of the invention is also effective as a high-speed conveyor, e.g., speeds in excess of 2,000 feet per minute, particularly when the conveyor may have open spaces therealong. Open spaces occur due to the conveyance of articles which may be spaced apart or fed to the conveyor in an intermittent fashion. The inventive conveyor has a generally flat belt configuration which is ideal for conveying articles such as baggage, packages or the like. Features of the inventive conveyor permit air support of the generally flat conveyor without loss of control over the lateral movement of the conveyor as it travels or without excessive wear which could result during high speed operation.An exemplary embodiment of the inventive conveyor is depicted in FIGS. 2 and 3 and is designated by the reference numeral 20. The conveyor 20 includes a plenum chamber 21 having opposing ends 23. The plenum chamber 21 is supported via the ends 23 by support members 25. The support members 25 position the plenum chamber 21 at the proper elevation so that the conveyor can interface with the appropriate feed and exit arrangements (not shown). The support members 25 are shown as beams but any structural member or arrangement can be utilized to support the plenum chamber 21.The plenum chamber 21 includes a bottom plate 27 and a top plate 29, these plates together with the sides 23 forming an interior 31. Strengthening ribs 33 can be positioned in the interior 31 where appropriate to provide additional support.The bottom plate 27 is shown with an incline toward the longitudinal axis of the conveyor. A drain plug 32 is located at a midpoint of the bottom plate 27 to facilitate removal of accumulated moisture or other unwanted materials. Of course, other configurations of the plenum chamber 21 can be utilized provided that the interior 31 can be pressurized to provide the air support for the conveyor belt.Still referring to FIGS. 2 and 3, the top plate 29 contains a plurality of orifices 35. The orifices 35 can be slots, round holes or the like and can be distributed as shown or be positioned in other configurations, uneven spacings, etc. A belt 37 is positioned adjacent the top plate 29. The top plate 29 functions as a support for the belt 37 in two modes. First, when the interior 31 is not pressurized by a source of air 38, such as a fan, blower or the like, the belt 37 rests on the plate 29. When the interior 31 is pressurized, air flows through the top plate orifices 35 and against the underside 39 of the belt 37. The air flow creates an air bearing or cushion of air of a given thickness to support the belt 37 while it is driven by a belt drive (not shown) for article conveying. The belt drive is conventional and a further description thereof is not deemed necessary for invention understanding.More specifically, air or any pressurizable fluid is pumped into the interior 31 from a simple low horsepower centrifugal fan or any air moving device. The air escapes through the series of orifices at or near the longitudinal axis of the conveyor. The air spreads out width-wise and lifts the belt 37 off the top surface 40 of the top plate 29. At the same time, the belt is propelled by a conventional drive system. Air is pulled along with the belt at approximately the same speed as the belt is driven. Air escapes along the belt side edges and at the entrance and exit ends of the conveyor. Air escapes more so at the exit end rather than the entrance end since the travel of the belt draws air with it.The top plate 29 is divided into three sections, a center generally flat section 41 and opposing outer sections 43, each angled or bent upwardly from the flat plane defined by the center section 41, see FIG. 2.The outer section 43 is illustrated in FIG. 3 as having a transition section 45 with a radius R and a generally straight section 47. The transition section 45 functions to bend the belt slightly or give it a steering action.The outer section 43 besides being defined by the radius R is also defined by the angle .theta. The bend or radius can vary depending on the particular conveyor application, e.g., from a tight bend when the radius is near zero to a gradual bend when the radius could be up to 20 inches. A preferred radius range is between 5 and 10 inches and more preferably 5 and 7 inches, e.g., 6.5 inches. Similarly, the angle .theta. could vary as well, ranging up to 60.degree., preferably 25.degree. to 35.degree., and more preferably 30.degree. The straight section 47 is shown being basically coincident with an exit angle defined by the end portion 48 of the transition section 45. However, the section 47 could be angled with respect to the end portion 48 of the transition section 45, if so desired.Besides providing a steering action to the belt 37, the angle or curved outer section 43 of the top plate 29 also functions as part of a belt edge guide designated by the reference numeral 50, see FIG. 2. The belt edge guide 50 assists in controlling belt steering or lateral movement and belt upward or vertical movement during belt travel.The belt edge guide 50 functions to direct air emerging from the underside 39 of the belt 37, around the belt edge face 51 and across the upper belt surface 53. As described in more detail below, the belt edge guide 50 also creates a zone of increased pressure over the belt upper surface 53 to control belt edge upward movement, particularly when the belt may have open spaces, i.e., spaces where no articles are being carried or a no loading situation.With specific reference to FIG. 3, the belt edge guide 50 includes an elongated bar 55 running generally parallel with the axis of the conveyor 20. The bar 55 is positioned between a guide 57 and the straight section 47 of the top plate 29. In FIG. 3, the bar 55 is shown secured to the guide 57 by the nut 59 and bolt 61 arrangement, the nut 59 extending through openings in the bar 55 and the guide underside 63. The guide 57 is shown supported by the member 25 at reference numeral 65. The guide 57 can also function with its upstanding surface 67 as a guide surface for an article 75 being conveyed on the belt 37, see FIG. 2.The arrangement of the bar 55, the guide 57 and the top plate 29 create a zone of high pressure over the belt surface 53. More particularly, air exiting from the underside 39 of the belt enters a recess 69 formed by the top plate 29, the underside 63 and the elongated bar face 71. The air, after entering the recess 67, passes over the upper surface 53 of the belt and out a slot 73. By reason of the reduced dimensions of the slot 73 as compared to the recess 69, a zone of higher pressure, e.g., greater than ambient pressure, is created above the belt surface 53. This zone of high pressure tends to force an edge portion of the belt toward the top plate 29. Thus, contact between the belt surface 53 and the underside surface 63 of the guide 57 is minimized or eliminated. This action is extremely significant when the belt is traveling at high speeds, greater than a 1,000 feet per minute and as high as about 2,200 feet per minute. Contact between the surfaces 53 and 63 at these high speeds could cause significant damage to the belt surface.In addition, since the conveyor 20 may be adapted to carry packages or luggage, see FIG. 2, the belt 37 may see open spaces where the belt is not uniformly loaded. Under these conditions, a tendency exists for the air bearing, i.e., the distance between the underside the belt 39 and the top surface 40 of the top plate 29, to increase and force the belt upwardly, including the belt edge surface 53. With the edge guide 50, air escaping from the sides of the belt is used to control and/or minimize upward belt edge movement. Consequently, the belt can be operated with intermittent article conveyance and, if desired, at high speeds without belt surface damage.To further enhance the zone of increased pressure, the underside surface 63 of the guide 57 can be bent or angled differently from the angle created by the straight section 47 or angles tangent to the transition section 45.When measured in either way, the difference in angling whereby the acute angle formed by surface 63 and a reference plane bisecting the flat section 41 of the top plate 29 would be greater than that formed by the straight section or tangents to the transition section 45 with respect to the same reference plane. The angling difference between the underside surface 63 and the tangents of the transition section 45 or straight section 47 serves to reduce the slot dimension 73 so that the zone of pressure in recess 69 is increased over a configuration wherein a relationship between the guide surface 63 and straight section 47 or tangents to section 45 is generally parallel.It should be understood that the design of the belt edge guide 50 is exemplary. Any configuration or means which would direct air from under the belt 37, around the belt edge face 51 and over its upper surface 53 to create the increased pressure zone can be utilized. For example, the guide undersurface 63 could be separate from the guide 57, particularly when the upstanding vertical guide surface 67 would not be needed, e.g., utilizing the conveyor 20 for both conveying articles, e.g., a feed run conveyor, and as a return
