AUTOMATIC LANE ADJUSTMENT SYSTEM

Abstract

A system, method and apparatus for adjusting lanes in a conveyor system including a conveyor having opposing outer side walls and a plurality of uprights along the side walls and two or more lane dividers positioned between the side walls. One or more rails are positioned between opposite uprights and a scissor mechanism is positioned along the rails and connected with respect to the lane dividers, the scissor mechanism configured to independently adjust lane width and offset.

Claims

1. A conveyor system comprising: a conveyor having opposing outer side walls and a plurality of uprights along the side walls; two or more lane dividers positioned between the side walls; one or more rails positioned between opposite uprights; and a scissor mechanism positioned along the rails and connected with respect to the lane dividers, the scissor mechanism configured to independently adjust lane width from an offset distance.

2. The conveyor system of claim 1 further comprising at least one linear slide engaged with the rails.

3. The conveyor system of claim 2 wherein the lane width is adjustable with the scissor mechanism and the offset is adjustable with the linear slide.

4. The conveyor system of claim 3 wherein the lane width and the offset are independently adjustable.

5. The conveyor system of claim 1 further comprising a plurality of sprockets positioned along the side walls, the plurality of sprockets connected to a chain configured to move the scissor mechanism and/or the offset.

6. The conveyor system of claim 1 further comprising a width ACME thread and an offset ACME thread positioned between each opposite upright, each dedicated to adjusting the lane width and the offset, respectively.

7. The conveyor system of claim 6 wherein the width ACME thread is non-backdriveable.

8. The conveyor system of claim 1 further comprising a pivotable arm for directing product into individual lanes between lane dividers.

9. The conveyor system of claim 1 further comprising one or more motors configured to move the scissor mechanism.

10. The conveyor system of claim 1 further comprising a hand crank configured to move the scissor mechanism.

11. The conveyor system of claim 1 wherein the scissor mechanism and the lane dividers are configured to maintain equal spacing of all lane widths.

DETAILED DESCRIPTION OF THE INVENTION

[0013] The present invention provides a system, apparatus and method for automatically adjusting lanes of a conveyor system. A conveyor system according to the subject invention is shown in FIGS. 1-3. The subject conveyor system may be used in connection with conventional conveyor systems including rollers, powered belts, skatewheels, chains, flexible conveyors, and others.

[0014] Conventional conveyor systems typically include fixed lanes that must be disassembled and reinstalled with new spacers to permit changeover of container sizes and configurations. The subject system preferably installs on existing systems and prevents or minimizes the need for time consuming changeover.

[0015] As shown in FIGS. 1-3, a conveyor 10 includes opposing outer side walls 20 and a plurality of uprights 30 along the side walls 20. The side walls 20 are intended to delimit the total width of the conveyor 10 and contain conveyed product within the conveyor 10.

[0016] Two or more lane dividers 40 are preferably positioned between the side walls 20. The lane dividers 40 are preferably generally rigid bars or rails that provide discrete lane paths for conveyed products.

[0017] One or more rails 50 are preferably positioned between opposite uprights. The rails 50 may be slide rails or a similar arrangement that permits movement of the subject mechanisms across the rails 50 and generally perpendicular to a direction of travel of the conveyor 10. Linear slides 70 may be positioned along the rails to enable smooth linear motion of the lane dividers 40. The linear slides 70 are preferably each connected to a divider 40 to enable free sliding movement of the respective dividers 40 into a desired position.

[0018] A scissor mechanism 60 is preferably positioned along the rails 50 and connected with respect to the lane dividers 40. The scissor mechanism 60 is configured to independently adjust lane width from the offset distance. As used herein, offset is the distance a lane arrangement is from a centerline (or a datum line) of the conveyor 10. As such, the scissor mechanism 60 can adjust both a distance within the lane and a distance between lanes, preferably independently. In an embodiment shown in the figures, the lane width is adjustable with the scissor mechanism 60 and the offset is adjustable with the linear slide 70 and rails 50. In this embodiment, the lane width and the offset are independently adjustable. The scissor mechanism 60 and the lane dividers 40 are preferably configured to maintain equal spacing of all lane widths, although differing widths may be preferable in some applications.

[0019] The scissor mechanism 60 may be driven by one or more motors 120 configured to move the scissor mechanism. Alternatively, or in addition, a hand crank 130 may be configured to move the scissor mechanism.

[0020] In one embodiment of this invention, a plurality of sprockets 80 may be positioned along the side walls 20. The plurality of sprockets 80 may be connected to a chain 90 configured to move the scissor mechanism 60, preferably in a synchronized fashion across the system.

[0021] The conveyor system preferably further includes driven ACME threads 102, 104 extending transversely across the lanes in association with each rail 50. Specifically, a width ACME thread 102 and an offset ACME thread 104 are positioned between each opposite upright 30, each dedicated to adjusting the lane width and the offset, respectively. The ACME threads 102, 104 are preferably non-backdriveable so as to prevent movement of the width or offset generated by the flow of conveyed products.

[0022] The invention illustratively disclosed herein suitably may be practiced in the absence of any element, part, step, component, or ingredient which is not specifically disclosed herein.

[0023] While in the foregoing detailed description this invention has been described in relation to certain preferred embodiments thereof, and many details have been set forth for purposes of illustration, it will be apparent to those skilled in the art that the invention is susceptible to additional embodiments and that certain of the details described herein can be varied considerably without departing from the basic principles of the invention.
