Description

CONVEYOR SYSTEM WITH ROLLER ASSEMBLIES
RELATED APPLICATION
The present application claims priority to U.S. Provisional Patent Application No.
62/087,453, filed December 4, 2014 and entitled "Conveyor System with Roller Assemblies", the contents of which are herein incorporated by reference.
BACKGROUND OF THE INVENTION
The invention relates generally to power-driven conveyors and more particularly to conveyors having rollers for manipulating the trajectory of articles through a conveyor system.
Many package- and material-handling applications require that conveyed articles be diverted to a side of a conveyor. Two examples are sorting articles off the side of a belt and registering articles against the side of the belt. U.S. Patent No. 6,494,312, "Modular Roller- Top Conveyor Belt with Obliquely-Arranged Rollers," December 17, 2002, to Costanzo discloses a conveyor system in which cylindrical rollers mounted in a conveyor belt on axles oblique to the direction of belt travel are actuated by underlying bearing surfaces on which the oblique rollers ride as the belt advances in the direction of belt travel. The contact between the rollers and the bearing surfaces causes the rollers to rotate as the belt advances. The rotation of the oblique rollers pushes articles atop the rollers across the conveyor belt toward a side of the conveyor. These oblique-roller belts work extremely well on planar bearing surfaces as long as the rollers are arranged to rotate at an angle between the direction of belt travel (defined as a roller angle of 0°) and about 30° or so from the direction of belt travel. For roller angles greater than 30°, the rollers slip too much on the planar bearing surfaces.
U.S. Patent No. 6,968,941, "Apparatus and Methods for Conveying Objects," November 29, 2005, to Fourney describes an improved bearing surface that accommodates a much greater range of roller angles. Instead of using a planar bearing surface, Fourney uses the outer peripheries of actuating rollers arranged to rotate on axes in the direction of belt travel. As the conveyor belt advances, the oblique belt rollers roll on the underlying actuating rollers, which are also caused to roll on their axes. Because the bearing surface on the periphery is rolling, slip is reduced and greater roller angles can be accommodated. The greater roller angles permit much sharper article-diversion trajectories than are possible with a planar bearing surface. But actuating rollers are more expensive and slightly more complicated than simple planar bearing surfaces.
U.S. Patent No. 7,588,137, "Conveyor Belt Having Rollers that Displace Objects,"
September 15, 2009, to Fourney describes a conveyor belt that includes multiple roller sets used to divert objects from the conveyor belt. The angles along which articles can be diverted from the conveyor are limited.
U.S. Patent Publication 2013/0192954, published August 1, 2013 and entitled "Multi- Directional Roller Assembly" (now U.S. Patent No. 9,978,879), the contents of which are herein incorporated by reference, describes a multi-directional roller assembly that may be driven by a conveyor belt below the assembly. The same conveyor belt conveys articles to and from a roller plate housing an array of multi-directional roller assemblies. The roller assemblies manipulate the trajectory of the articles, or pass the articles straight along the roller plate and back onto the conveyor belt. The conveyor belt is diverted below the roller plate to drive the roller assemblies. The conveyor belt may experience high tensions.
Furthermore, the transition of articles off the conveyor belt, onto the roller plate and back onto the conveyor belt may alter the desired spacing between articles, in addition to presenting unnecessary instability.
SUMMARY OF THE INVENTION
A conveyor system employs a roller plate housing an array of roller assemblies for manipulating the trajectory of an article and a series of narrow conveyor belts passing over the top of the roller plate between roller assemblies and back under the roller plate. The narrow conveyor belts are movable relative to the top surface of the roller plate. In a raised mode, the narrow conveyor belts convey articles over the roller plate. In a lowered mode, the narrow conveyor belts pass articles onto the roller plate and into contact with the roller assemblies, which manipulate the trajectory of the articles. Below the roller plate, the narrow conveyor belts in the returnway may help drive the roller assemblies.
According to a first aspect, a conveyance device comprises a sorting plate having an array of roller assemblies for contacting and directing an article of conveyance along a selected trajectory, at least one conveyor belt passing between two roller assemblies and an actuator for selectively raising and lowering the conveyor belt relative to the sorting plate.
According to another aspect, a conveyance device comprises a sorting plate having a plurality of rows of roller assemblies for contacting and directing an article of conveyance along a selected trajectory, a plurality of tracks passing between roller assemblies, a plurality of narrow conveyor belts contained in the tracks, and an actuator for varying the distance between the narrow conveyor belts and the roller assemblies.
According to another aspect, a method of sorting articles comprises the steps of conveying articles towards a sorting plate having a plurality of roller assemblies using a series of narrow conveyor belts and adjusting a distance between the roller assemblies and the narrow conveyor belts depending on an orientation of the roller assemblies.

A conveyor system includes an array of roller assemblies and a plurality of narrow conveyor belts passing over the roller plate between the roller assemblies. The invention will be described below relative to certain illustrative embodiments, though one skilled in the art will recognize that the invention is not limited to the illustrative embodiments.
FIG. 1 shows a conveyor system including a sorting plate 10 that comprises a plurality of roller assemblies 20 for selectively changing the trajectory of a conveyed article. The roller assemblies 20 are arranged in a pattern of alternating rows, though the sorting plate 10 may have any suitable number, size, configuration and arrangement of roller assemblies. The roller assemblies 20 are housed between upper and lower plates, as described in U.S. Patent Publication 2013/0192954, published August 1, 2013 and entitled "Multi-Directional Roller Assembly", the contents of which are incorporated herein by reference, though the invention is not limited to the multi-directional roller assemblies there described.
The sorting plate 10 includes a plurality of narrow conveyor belts 50. The belts 50 operate in at least two modes: a raised mode and a lowered mode. In one embodiment, an actuator selectively raises or lowers the drive belts relative to the sorting plate 10 to switch between modes. In a raised mode, one or more of the drive belts is raised above the top surface of the sorting plate 10, so that a product carried towards the sorting plate by the drive belts will pass over the sorting plate without contact with the roller assemblies 20. In the raised mode, the belts 50 serve as the primary conveyor of articles over the sorting plate 10. In a lowered mode, an actuator lowers the conveyor belts 50 relative to the top surface of the sorting plate, so that an article conveyed to the sorting plate 10 by the belts 50 contacts the roller assemblies 20 which then direct the article in a selected direction, depending on the orientation of the roller assemblies. In one embodiment, the belts 50 return under the sorting plates and also serve as drivers for the roller assemblies 20. As show, the narrow conveyor belts 50 have a width sufficiently narrow to allow passage of the conveyor belt between adjacent roller assemblies 20 in the sorting plate 10.
The individual roller assemblies 20 are arranged to allow clear passage of the narrow belts in either situation in either mode. The roller plate 10 may include tracks between different roller assemblies for containing the belts 50. The tracks keep the belts in a straight orientation relative to the motion and support the weight of the belts and conveyed articles. In one embodiment, an actuator selectively moves the tracks up and down to expose the conveyed articles to the roller assemblies 20. In another embodiment, the conveyor belts 50 can remain vertically stationary while the roller assemblies 20 move up and down to alternate between the two modes.
In one embodiment, the actuator moves only the top (carryway) portion of the belts
50 between raised and lowered positions. In another embodiment, the actuator moves an entire belt 50 or series of belts 50, or the roller plate 10 may be moved relative to the top portion of the belts 50. The tracks or the belts 50 or the roller assemblies 20 or the roller plate 10 may be raised and lowered independently of the actual roller assemblies using cams, motors, air cylinders, hydraulic cylinders, magnets, springs or any suitable combination of actuators.
FIG. 2 is a schematic side view of the conveying system of FIG. 1. The narrow belts 50 convey an article 60 towards the sorting plate 10. In a raised mode, the narrow belts 50 convey the article at belt speed over the sorting plate 10. In a lowered mode, the narrow belts 50 convey the article to the sorting surface of the sorting plate 10, where the roller assemblies act on the package. The narrow belts 50 return below the sorting plate 10. The narrow belts may engage a secondary belt 70 below the sorting plate 10 to drive the roller assemblies 20. Alternatively, a motor or other suitable driver may be used to drive the roller assemblies 20.
FIG. 3A is a side view of the sorting plate 10 with the narrow belts 50 raised relative to the top surface of the roller plate 10. In a raised mode, the top surface of the narrow belts 50 remains the conveying surface for conveyed articles. The conveyed article does not contact the roller assemblies as it passes over the sorting plate 10.
FIG. 3B is a side view of the sorting plate 10 with the narrow belts 50 lowered relative to the top surface of the sorting plate 10. In the lowered mode, the top surface of the belts 50 is even with or below the tops of the roller assemblies, so that the roller assemblies 20 contact the conveyed article. Each roller assembly 20 is selectively oriented and actuated to manipulate the trajectory of a conveyed article.
Any suitable means for raising and lowering the belts 50 may be used. In one embodiment, the vertical motion of the belt 50 over the roller plate 10 may be connected to the orientation of the roller assemblies 20 within the plate. For example, FIGS. 4A and 4B show a rotational ramp 90 for guiding and changing the height of a belt 50 across a roller plate 10. The rotational ramp 90 forms a track 91 with walls 92 for guiding a narrow conveyor belt over or through a roller plate. The rotational ramp 90 is designed so that the track 91 is in a high position (FIG. 4A) when the roller assemblies are in a pass-through position, so that the roller assemblies do not contact the conveyed article. When the roller assemblies are oriented in a sorting orientation, the track 91 is in a lower position (FIG. 4B) to lower the conveyor belt 50 passing through the track 91, allowing an article conveyed by the conveyor belt 50 to contact the roller assemblies. The rotational ramp comprises a top portion 95, which is fixed to the narrow belt track and a bottom portion 96, which rotates with the roller assemblies or connected gearing. The bottom portion and top portion including bearing surfaces, such that rotation of the bottom portion 96 relative to the top portion 95 pushes the top portion 95 up to raise the track 91.
FIG. 5 is a schematic overhead view of a belt 50 passing through a pair of roller assemblies 20 according to another embodiment of the invention. In the embodiment of FIG. 5, each roller assembly 20 includes peripheral teeth 22 that engage a rack gear 24 or other actuator to selectively orient the roller assemblies 20. The rack 24 includes ramps 26 for selectively raising and lowering the belt 50 relative to the roller assemblies 20, depending on the orientation of the roller assemblies. When the roller assemblies are oriented in a pass- through orientation, the ramps 26 move inwards to push the belt 50 up so that the roller assemblies do not contact the conveyed article. When the rollers assemblies 20 are oriented in a sorting orientation, the ramps 26 pull away from the belt to lower the belt 50.
Both the rotational ramp 90 shown in FIGS. 4A and 4B and the linear ramp 26 mechanisms can serve the dual purpose of transferring motion from one roller assembly 20 to another while also raising and lowering the belt 50 or a track containing the belt.
The narrow conveyor belts 50 allow a continuous conveying surface to be maintained. Since the belts 50 follow a much straighter path, the belt tension, belt wear and consumed power is reduced.
As these few examples suggest, the scope of the invention is meant to be defined by the claims and not limited to the details of the described versions.
