PAIENTEII EU 1 snmunrg ARTICLE HANDLING SYSTEM This invention relates to an article handling system,
  • the majority of the vehicle mounted conveyor systems of the prior art are used for direct loading or unloading only and not for selectively delivering a particular container to a particular position on the truck without having to remove other containers. It is known to use an endless conveyor on a truck body for select delivery by moving articles through a generally oval path; however, such systems are impractical from a cost standpoint in that entirely too much free space must be allowed for the containers on the conveyor to make the turns around the sharp corners of the truck body. Further, the mechanism of the conveyor itself has generally been of a rather bulky construction further reducing the space that is available for hauling cargo. The system of this invention permits the carrier to maximize the usage of the space within the truck body; and is particularly adapted for standardized containers having pallet bases compatible for use with fork-lift loaders.
  • Standardized containers are desirable in that they facilitate the use of the optimum amount of space in a vehicle body and are more suitable for stacking.
  • the container itself must be of a particular design and many times is required to be specially fitted with dollies or have other miscellaneous hardware attached thereto which is only useful when used with the particular mechanized system for which it was originally adapted.
  • the basic concept under which the mechanized system of this invention operates involves the sectioning of the truck body into a plurality of contiguous, generally square areas aligned in two longitudinal rows. Each of the squares receives a container with the exception of one which is left blank.
  • a parallel pair of walking beam type conveyors are mounted on the truck floor and effect longitudinal movements of the two rows. The transverse movement, or the shifting of containers from one row to another at the corners is accomplished by driven-roll type conveyors positioned at each end of the walking beam conveyors.
  • Walking beam conveyors for trucks are known in the prior art but are generally more complicated and consume more space than the walking beam conveyor of this invention. Further, truck mounted walking beams of the prior art are generally used for straight loading or unloading only, and not in combination with transverse conveyors to effect load movements in a rectangular path within the confines of a vehicle body under the concepts outlined earlier herein.

  • the article handling system of this invention will be described with respect to its installation on a vehicle truck body; however, it is to be understood that it has utility other than confined areas, whether movable or stationary. Further, the article handling system of this invention can be used for direct loading or unloading of vehicles ot the like in addition to being useful in selective delivery of the type set forth in my earlier copending application.
  • Examples of such containers are those disclosed in copending applications Ser. No. ll4,257 filed Feb. 10,1971 entitled CONTAINER and Ser. No. 141,199 filed May 7, 1971, entitled MO- BILE CARGO STORAGE UNIT.
  • the vehicle floor is sectioned into imaginary squares aligned in two rows, Al-A9 and B1-B9, respectively as shown in FIG. 2.
  • Each of the squares is occupied by a container with the exception of one, in this case square B9 which is left vacant. It is this vacant area which permits the containers to be shifted in transverse and rectilinear movements, as will hereinafter be more fully described.
  • the containers can be stacked to more fully maximize the space of the trailer body.
  • step 2 the longitudinal conveyor or walking beam conveyor 18 is actuated to move the entire row of containers occupying positions A1 through A8 to position A2 through A9.
  • step 3 the transverse conveyor 28 is actuated in step 3 to move the container in the space B1 to space Al.
  • step 4 the longitudinal conveyor 16 is actuated to move the containers in stations B2 through B9 to stations Bl through B8. This sequence is definedas indexing one position or one square.
  • One complete circuit is defined as indexing until the original arrangement is regained.
  • one circuit '(original container returned to starting position) requires seventeen indexing sequences of four steps each.
  • a particular container for example, the one occupying the position in station A9 at the front end of the trailer, can be delivered to the position B1 at the rear of the the trailer where it can be conveniently removed by fork lift truck or the like without having to remove any other containers from the trailer.
  • this system permits the utilization of a maximum amountof space within the truck body.
  • a first set of axles 44 are journaled in the side plates 40 and 42 at longitudinally spaced positions generally corresponding to the location of the ramps 32.
  • First or lower rollers 46 are journaled on each of the axles 44 and have peripheries which contact the surface of the ramps 32. The peripheries of the rollers may extend below the edges 48 as shown.
  • a second set of axles 50 are journaled in the side plates 40 and 42 and generally lie in a plane above that of the first set of axles, and have rollers 52 with peripheries lying above the edges 54 of the plates 40 and 42 so that they contact the movable beams 56.
  • Movable beams 56 joined by suitable transverse connecting members 58 are supported by the rollers 52 on the intermediate beams 38.
  • Piston-cylinder assemblies 64 and 66 comprise the drive means for reciprocating the intermediate beams 38, and are attached at one end to stationary transverse member 68, which is affixed to the floor and to the stationary beams 36, and at the other end the cylinder assemblies 64, 66 are attached to transverse member 60 which connects the intermediate beams 38.
  • Hydraulic cylinder assembly 70 comprises the drive means for reciprocating the movable beams, and is affixed at one end to the stationary transverse member 68 and at the other end to transverse member 58 which connects the movable beams.
  • the stroke length of cylinders 64 and 66 generally corresponds to the length of the ramps which is approximately 6 inches, with a 1 inch elevation.
  • the stroke length of the cylinder 70 is the length of a standardized container, which in a preferred embodiment is approximately 54 inches.
  • the intermediate beams 38 are in the down position such that the movable beams 56 supported thereon are below the upper edges 37 of the stationary beams 36 as shown in FIG. 5.
  • the containers will rest on the edges 37, with the exception that when a container is in one of the corner positions, it will rest on the rollers 72 as best seen in FIG. 5.
  • the upper peripheries of the rollers lie above the edges 37 of the fixed beams, but below the upper surfaces of the movable beams when the movable beams are in the fully raised position.
  • the movable beams 56 When the intermediate beams 38 are pulled up the ramps 32 by extending the cylinders 64 and 66, the movable beams 56 will be raised above the upper edges 37 of the stationary beams 36, thereby lifting the containers off of the edges 37.
  • the movable beam 56 is then shifted by the hydraulic cylinder 70 of the power unit 24 or 26 to move the containers supported therein one container length, after which the cylinders 64 and 66 are retracted thereby lowering the intermediate beams and movable beams 56 to again place the load on the upper edges 37 of the stationary beams 36.
  • the movable beam is then retracted back to its original position by the cylinder 70.
  • To move the containers in the reverse direction the movable beams 56 are first extended, the intermediate beams are raised on ramps 32, and the beams 56, now supporting the load, are retracted.
  • the transverse conveyor mechanisms 28 and 30 each comprises sets of idle rolls 72 generally aligned with each end of each of the longitudinal conveyors 16 and 18, the rollers being journaled on axles which extend in a direction parallel to the direction of the longitudinal conveyors.
  • the sets of idle rolls are spaced by a set of driven rolls 74, which are driven by a conventional electrical or hydraulic reversible rotary motor 76 which drives a central shaft 78 and laterally spaced shafts 80 and 82 by means of a sprocket and chain drive generally indicated by the numeral 84.
  • the driven rolls 74 are covered by a suitable gripping surface for frictionally engaging the underside of a container set thereon to shift it from one longitudinal conveyor to the other in the proper sequence.
  • Limit switches 300-314 can be employed to energize the operation of the longitudinal and transverse conveyors in the proper sequence during indexing of the containers. Switches 300, 302, 304 and 306 are energized for actuation of the containers in the counterclockwise direction, and switches 308-314 are energized during clockwise movement.
  • conveyors 16, 18, 28 and 30 comprising the total article handling system of this invention can be readily adapted to existing truck bodies by simply attaching the stationary beams 36 and the brackets journaling the rollers of the roller conveyors to the floor 20 by conventional fastener means.
  • the various units can be marketed in kits for assembly by the purchaser and require no particular expertise for assembly or operation.

  • the ramps are made integral with the intermediate beams. and the rollers are attached to the floor.
  • the intermediate beams 38 are provided with upper rollers 52 for supporting movable beams 56 as in the first embodiment. Plates are joined to side plates 40 and 42 and are inclined at approximately the same angle as the ramps 32 in the first embodiment and are of approximately the same length. Rollers 82 are rotatably mounted on axles 84 journaled in brackets 86. The brackets 86 are in turn fixedly attached to the base 34 of the fixed beams 36.

  • the cylinders 64 and 66 are extended to reciprocate beams 38 such that the undersides of plates 80 ride up on rollers 82 to raise the beams 38 and therefore, beams 56, the latter being raised above the edges 37 of stationary beams 36.
  • FIGS. 11 and 12 A further modified form of the invention is shown in FIGS. 11 and 12, wherein ramps 132 are affixed in an inverted manner to movable beams 156, and stationary beams 136 are affixed to the floor of the vehicle.

  • FIG. 13 The hydraulic system employed to actuate the cylinders in proper sequence is diagrammatically illustrated in FIG. 13. Only one of the cylinders used to vertically raise the conveyor, cylinder 64, is shown. It is to be understood that cylinder 66 is connected in parallel with cylinder 64 and will be accuated in unison therewith.
  • the system includes four sequencing valves 200, 202, 204 and 206, designed to open upon sensing a pre-determined pressure, two pilot-operated four-way valves 208 and 210, a 'main control valve 212, which is a manually operated four-way open center valve and a pump 214 capable of working pressures to 1,500 p.s.i. and instantaneous peak pressures to 2,500 p.s.i.
  • valve 212 is shifted to the load position and valves 208 and 210 are in the B and A positions, respectively. The latter two valves are detented in one of their two positions until shifted by fluid pressure. Fluid pressure from pump 214 is introduced into chamber 63 of cylinder 64 causing the cylinder to extend. The fluid under pressure will also be transmitted to chamber 69 of cylinder 70, thereby maintaining cylinder 70 in the retracted position.
  • the cylinder 70 shifts the movable beams of the walking beam conveyor one position or one container length.
  • the pressure build-up will be sensed by sequencing valve 202 causing the latter to open .to transmit fluid pressure to pilot operated four-way valve 210 to shift the latter to the B position. Pressure will be transmitted to chamber 65 of cylinder 64 and also to pilot operated check valve 216 causing the valve to open and permitting the piston in the cylinder 64 to retract.
  • the pressure build-up in chamber 65 will be sensed by sequencing valve 204 whereby the latter will open to transmit pressure to pilot operated four-way valve 208 to move the valve back to the B position, whereupon fluid under pressure is introduced into chamber 69 of cylinder 70 causing the cylinder to retract.
  • sequencing valve 200 When the cylinder is fully retracted, the pressure build-up in chamber 69 will be sensed by sequencing valve 200 which will open to permit fluid under pressure to shift pilot operated four-way valve 210 back to the A position.

  • the force required to open the check valves is less than 100 p.s.i.
  • the forces tending to extend the cylinder 64 when in the retracted position will be minimal, therefore no check valve is required for the chamber 65.
  • chamber 71 of cylinder 70 a check valve is required for chamber 69 and is actuated at about 200 p.s.i. This check valve prevents the cylinder 70from extending in the reverse cycle during the step of lowering the intermediate and movable beams while the cylinder is in the retracted position.
