    [0001] [001] This application claims the benefit of United States Patent Application no. serial number 13/795112, filed on March 12, 2013, which is hereby incorporated by reference. FUNDAMENTALS AND SUMMARY
    [0002] [002] The description refers generally to conveyors and, more particularly, to a separating conveyor.
    [0003] [003] It is known that employing a separating conveyor to unpack randomly oriented items. Examples of such traditional separating carriers can be found in U.S. Patent no. US5769204, entitled "Separator conveyor system having package return conveyors" which was granted to Okada and Ydoate on June 23, 1998, and US Patent no. US5400896, entitled "Unloader transporter", which was granted to Loomer on March 28, 1995. Both of these patents are hereby incorporated by reference.
    [0004] [004] Another traditional separator carrier is known as the Accord ™ separator of the present depositor. This separator employs a centrally shaped conveyor belt outwardly bounded by sets of driven rollers that are only skewed in a direction seen from above. These Accord ™ Separator rollers are horizontally complementary to each other and are vertically higher than the central conveyor belt. While this Accord ™ Separator is a considerable improvement in the industry, it still allows for wrapping and packaging to stack again on top of each other as they move from the rollers to the central conveyor belt.
    [0005] [005] In addition, US patent no. US2566417, entitled "Switching Carrier" which was granted to Holm on September 4, 1951 discloses a switching mechanism between the two branches of conveyors. This switching conveyor is completely unrelated to a separating conveyor, however, it employs divergent side rollers at an angle down and back. However, it is worth mentioning that this previous device has laterally pivoting control rollers that are passive.
    [0006] [006] In accordance with the present invention, a conveyor machine is provided. In another aspect, a separating conveyor employs obliquely three-dimensionally skewed drive rollers with angularity offset from a main feed and the downstream direction, outside the edge of an adjacent driven conveyor that has a moving top surface in the primary feed and the direction downstream. An additional aspect provides a conveyor belt moving downstream or rollers that are vertically higher than the adjacent inclined and converging side drive rollers. A method of using an unstack separator for packages is also disclosed.
    [0007] [007] The present separating conveyor is advantageous over conventional systems. For example, the present conveyor conducts packages in an upward and converging manner towards the tip over the adjacent conveyor at the same time, preventing stacking side by side of packages, such as packages and, especially, envelopes. The present separating conveyor significantly improves the efficiency of separation yield, thus decreasing the traditionally observed recirculation load, while additionally having problems with automatic downstream movement and electronic reading of package barcode addresses due to traditional stacking concerns that otherwise it hides the lowest of the stacked packages. Additional advantages and features of the present invention will be determined by the following description and the appended claims, taken in conjunction with the accompanying drawings.

    [0021] [021] A preferred embodiment of a conveyor machine 21 is shown in Figures 1-3. The conveyor machine 21 includes a feed conveyor station 23, a separator conveyor station 25, an elimination conveyor station 27, the recirculating conveyor stations 29, a conveyor exit station 31, a metering conveyor station adjustable speed feedback 33, and an automated address reading and sorting station. Various packages, such as mailboxes 35 and generally flat envelopes 37 capable of supporting 8½ by 11 inch letters, are placed over the feeding station 23 in a somewhat random manner, such as by dumping a container or bag of packages into them. The feed conveyor station 23 further includes an inclined conveyor section 43 which then lifts and drops the packages for separator station 25. In addition, several legs 39 and protective fences 41 are provided along the sides of the conveyor machine 21.
    [0022] [022] Reference should now be made to Figures 3-9 which illustrate further details of the separator 25. The separator 25 has a central transport section 51, preferably a longitudinally elongated and continuous conveyor belt 51, with an upper surface 53, for the frictional contact against a bottom face of packages 35 and 37. Conveyor belt 51 is wrapped around at least front and rear pulleys 55 that rotate around axes of rotation that are horizontal and perpendicular to a feed direction primary and longitudinal 61. Conveyor 51 loads and transports packages located in the same feed direction 61. Conveyor belt 51 is driven by an electric motor 63 and drive pulley mounted on the bottom side of separator 25.
    [0023] [023] A pair of mirror image of sets of driving and converging rollers 65 are located laterally off the central conveyor belt 51. Each of these rollers 65 is preferably circular-cylindrical, metallic and rotates about its central axis 67. Internal ends 69 outer ends 71 of rollers 65 are supported by stationary supports 73 and bearings in such a way that each roller 65 is generally elongated laterally between ends 69 and 71, with the exception of some short front and rear rollers 75. Some of the rollers 65 include an O-Ring 77 elastomeric sealing ring adjacent in the middle of them. An electric motor 81, outlet pulleys 83 and continuous belts 85 frictionally drive the bottom of each set of rollers 65 in such a way that the upper surfaces 87 of rollers 65 rotate in a general direction, downstream and converging 89 essentially towards conveyor belt 51.
    [0024] [024] As can be better seen in Figures 4 to 6, 8 and 9, the upper surface 87 and the axis of rotation 67 of each separator roller 65 are slanted three-dimensionally and obliquely with their outer end 71 oriented downstream (when seen top, as in Figures 4 and 6) and bottom (as seen from the side and end as in Figures 8 and 9) in relation to the inner end 69. Thus, each separator roller 65 is tilted upward in the direction of feeding central 61 by 8 ° to 20 ° outside the horizontal, and more preferably 8 ° to 10 °, at angle α; more inclined angles can be used if high friction rollers are used. In addition, seen from above the angle β of inclination of each upper surface of the roller 87 and the axis 67 are from 15 ° to 40 ° and more preferably about 20 ° in relation to the primary feed direction 61. The specific three-dimensional skewed angles advantageously they cause the packages of the drive rollers 65 to converge on the central conveyor belt 51 while also stopping the stacking of packages.
    [0025] [025] It is noteworthy that the upper surface 53 of the conveyor belt 51 is located vertically 1 to 2mm greater than d above the highest point of rollers 65. However, a projection line 91 from the upper surface 87 of each roller 65 it also projects a distance d of about 1 to 2mm above the corner next to the conveyor belt 51. The elevated nature of the conveyor belt 51 and the three-dimensionally skewed separating roller 65 prevent the stacking of packages, especially laterally adjacent envelopes 37, a since the edges of the adjacent packages act as thicker packages that abut each other by means of an edge in contact with a lower part, instead of a traditional coplanar arrangement, which causes the packages to slide above or below each other . In addition, the present construction causes the packages to move inward and upward until an inflection point is reached with respect to the package's center of gravity. Thereafter, the center of gravity of each of the packages 35 and 37 is controlled by a central conveyor belt 51 and is no longer driven by the roller 65. It is also noteworthy that the lateral width w of the conveyor belt 51 is at least 100 mm, and more preferably at least half of the typical packet width, still less in a lateral direction of the elongation W of each adjacent nominal roller 65 (as distinguished from some short rear or front rollers 75).
    [0026] [026] Reference should be made to an alternative mode of execution of separator 125 of Figure 10. In this variation, a single upward set of drive and converging rollers 165 is employed adjacent to a single drive and higher conveyor belt 151. This conveyor belt 151 is laterally wider than in the previous version. In addition, an upper contract surface of the package 187 and axis of rotation 167 of each drive roller are three-dimensionally skewed with respect to a primary and central feed direction as with the previous embodiment.
    [0027] [027] Figure 11 illustrates yet another variation of the separator 225. In this construction, a pair of three-dimensionally biased and laterally extruded drive rollers 265 are provided like that of the first execution mode. However, a central conveyor employs a set of drive rollers 251, each having a rotation axis 295 oriented perpendicularly to the downstream primary feed direction. The upper contact surfaces of the package 253 of the central transport rollers 251 are raised above the extruded converged separation rollers 265. The rollers 265 and 251 are each circular cylindrical and laterally elongated by at least 25mm and more preferably, at least , 100mm.
    [0028] [028] The elimination station 27 includes a central strip of the conveyor 301, or alternately drive rollers, which are centered between the extruded set of angularly diverging rollers 303. The extruded diverter rollers 303 are driven by an electric motor and underlying friction belt mechanisms. The extruded rollers 303 are horizontally complementary with each other, although they can be skewed three-dimensionally. In other words, the axis of rotation and the upper surface of each of the diverging elimination rollers 27 are obliquely angled with respect to the downstream feed direction 61 in only a top view, but not skewed or angled or in a forward view. end or side. In addition, a set of rails 305 or walls are stationary angled to direct remaining packages side by side on the rollers 303 away from the conveyor belt 301 and towards recirculation belts 29. An exemplary disposal station is described in patent no. US5701989, entitled "Carrier for removal of an article transported alongside another article" which was granted to Boone et al. on December 30, 1997, and is hereby incorporated by reference.
    [0029] [029] Another alternative embodiment of separator 325 is shown in Figures 12 and 13. This variation includes laterally individualized and converging sets of roller wheels 365 on both sides extruded from a central conveyor belt 351. Roller wheels 365 are powered by electric motors and 351 conveyor belt is also driven by an electric motor. Each roller wheel 365 is three-dimensional with its oblique axes compensated at angle β with respect to the central feed direction 361 in a top view, and angle of deviation α down towards its grouped ends drawn in relation to a horizontal plane defined by an upper contact surface of the belt package 351. The coaxial axes of each side group of the roller wheels 365 are stationary defined by their vertical supports.
    [0030] [030] Although several modes of execution have been described, it should be understood that other variations can be made. For example, a tapered driven roller can be used, although many of the present advantages will not be seen. In addition, at least 15, and more preferably at least 30, drive separator rollers can be used on each side of a central conveyor belt, however, a greater or lesser amount can be used, although certain advantages cannot be achieved. The roller and belt drive actuators and transmissions can alternately be varied to use pneumatic motors, sprocket and transmission set, cables, gears and transmission shafts, and many other mechanisms, although certain advantages cannot be seen. Individual elements or aspects of a particular embodiment are generally not limited to that particular embodiment, but, where applicable, are interchangeable and can be used in a selected embodiment, even if it is not specifically shown or described. The following claims are intended to cover these and any other departures from revealed modes of execution that fall within the true spirit of this invention.
