Abstract: Disclosed is a reciprocating floor conveyor having a separable floor unit and power drive unit (24). The floor unit includes a bottom frame (38, 40, 42, 44) and at least three sets of elongated reciprocatable floor members (26, 28, 30) which are supported on the bottom frame for independent longitudinal reciprocation in a single plane between start and advanced positions. A separate transverse drive beam (32, 34, 36) for each set of floor members (26, 28, 30) is connected to the underside of its respective set of floor members (26, 28, 30). The power drive unit includes a separate drive leg (54, 56, 58) for each set of floor members (26, 28, 30). Each drive leg is detachably connectable to a separate transverse drive beam (32, 34, 36) to reciprocatably drive it and its set of floor members (26, 28, 30). Each drive leg (54, 56, 58) is mounted to swing forwardly and rearwardly about a pivot point (60, 62, 64). A separate drive motor (66, 68, 70) for each drive leg ( 54, 56, 58) is operably connected (92, 94, 96) to swing the drive legs (54, 56, 58) to, in turn, move the drive beams (32, 34, 36) and the respective connected floor members (26, 28, 30) between start and advanced positions. The drive motors (66, 68, 70) operate in sequence to move a majority of the drive legs (54, 56, 58) together in one direction and then to return each drive leg (54, 56, 58) separately in the opposite direction. In this manner, the floor unit and power drive unit may be separated for independent transportation thereof and for interchange between other similar floor units and power drive units.

Abstract: Plug-together joints are formed between floor members (10, 10') and drive beams (18, 18'). These connections may comprise a pin or insert (72) secured to the drive beam (18) and a box or socket (52, 54) secured to the floor member (10). Or, it may comprise a box or socket (176, 178) secured to the drive beam (18') and an insert or pin (188) secured to the floor member (10'). Alternatively the connection may comprise an abutment block (198) secured to the floor member (10") which longitudinally engages between vertical push/pull members (210, 212), or a vertical projection (226) secured to the drive beam (18") which engages between a pair of abutment blocks (198) secured to the floor member (10"). The plug-together connection is used in a reciprocating floor conveyor of a type having slide bearings (122) for the floor members (10, 10') which allow the floor members (10, 10') to be snapped into place from above. The floor may also include hold down members (90) which are secured to the guide beams (14) for the floor members (10, 10') and which are also constructed to allow the floor members (10, 10') to be snapped into place from above. The hold down members (90) include hold down wings (100, 102) which, when the floor member is in place, locate lower edges (104, 106) above inner edge portions (84, 82) of the floor member (10, 10'). This puts the hold down wings (100, 102) into positions to block upward movement of the floor members (10, 10').

Abstract: This invention relates to improvements in reciprocating floor conveyors. A problem with some reciprocating floor conveyors is that they are not capable of being mounted in relatively narrow spaces. This invention divides the hydraulic drive assembly into two small size assemblies, each of which is capable of being mounted into a relatively narrow space. In each assembly, piston rod portions (42, 45, 44, 48) of two linear hydraulic motors (16, 20, 18, 22) are connected at their opposite ends to two spaced apart transverse frame members (50, 52, 54, 56). A cylinder (84) is driven back and forth along each piston rod (42, 46, 44, 48). Two transverse drive beams (24, 28, 26, 30) are provided. Each drive beam (24, 28, 26, 30) is directly connected to an associated one of the cylinders (84). The transverse drive beams (24, 28) of the first assembly are connected to the first and third set of floor slat members (40). The transverse drive beams (26, 30) of the second assembly are connected to the second and fourth set of floor slat members (40). The two assemblies (10, 12) are axially spaced apart. The linear hydraulic motors (16, 18, 20, 22) are operated for simultaneously moving the floor slat members (40) in one direction, for advancing a load, and for sequentially retracting them in the opposite direction.

Abstract: A plurality of floor members (40, 58, 106) are supported on guide beams (16, 18, 60, 102). The guide beams (16, 18, 60, 102) are spaced apart such that the floor members (40, 58, 106) have spaces between their side portions. The guide beams (16, 18, 60, 102) have oppositely directed flanges (26, 78, 80, 112, 114) secured to their tops. Bearing members (30, 116) slip over these flanges and rest on top of the guide beams (16, 18, 60, 102). Bottom members (20, 64, 98) extend laterally between the guide beams (16, 18, 60, 102), to form channels in the regions between the floor members (40, 58, 106). In one embodiment, refrigerated air is directed through these channels. In a second embodiment, the channel is used to collect small particles of ice and ice water. In a third embodiment, garbage is allowed to enter into the channel space. The sidewalls (108, 110) of the floor members (106) engage this garbage and move it when the floor members (106) are moving and hold it when the floor members (106) are stationary. The floor in which refrigerated air is circulated through the channels, and the floor in which small ice particles and ice water are collected in the channels, is set on an insulated base. The garbage conveying floor may be set on an incline, for lifting garbage up from a lower level to an elevated level above the open top of a container (92) provided for collecting the garbage (96).

Abstract: A unitary framework for a reciprocating floor conveyor is positioned within a space between a pair of longitudinally extending main beams (110), which may constitute portions of a preexisting support structure in a truck or trailer, for example. Telescopic tubular connector members (102) carried by a plurality of outwardly projecting support arms (18) are telescopically moved outwardly to place their outer ends against inner surface portions of the beams (110), and such outer ends of connector members (102) are welded to the beams (110). The telescopic engagement between these members (102) and the outwardly projecting arms (18) hold the framework in position. Then, the inner ends of these connector members (102) are welded to the arms (18), for completing the connection at these locations. The framework comprises a pair of longitudinally spaced apart, laterally extending king post trusses (10, 12), the apexes of which are directed downwardly. These trusses (10, 12) are interconnected by a pair of laterally spaced apart, longitudinally extending tie beams (14, 16). The tie beams (14, 16) are connected to the ends of, and form portions of, a pair of slide bearing assemblies (30, 32) which are carried by the two trusses (10, 12). These bearing assemblies (30, 32) include aligned guideways for receiving opposite end portions of longitudinal drive tubes (34, 36, 38).

Abstract: A drive unit for a reciprocating floor conveyor has a piston component (90) with an outer end longitudinally fixed to a transverse mounting member and a movable cylinder component (92) with a tubular extension (102). A slide bearing (104) supports and guides the tubular extension (102). The drive unit, including the tubular extension, acts as a structural beam. In a first embodiment, each floor member of the conveyor has its own drive unit to provide a powerful drive assembly for heavy loads. In a second embodiment, a plurality of drive units are part of a compact frame (302) having two longitudinal frame members (308) and two transverse mounting members (304, 306). The drive units are mounted in a window defined by the frame (302). A plurality of transverse drive beams (330), one for each drive unit, are connected to the drive units and reciprocate between the transverse mounting members (304, 306). This provides a compact and lightweight drive assembly that may be used for lighter loads.

Abstract: Adjacent base sections of a base structure of a reciprocating floor conveyor are connected along longitudinal side edges by a tongue and groove joint. Side portions of adjacent sections form a guide beam. The groove and tongue portions of the joint are formed at lower ends of angled inner walls extending downwardly from the top of the guide beam. The inner walls together define an upwardly opening space above the joint. The space is large enough, and the groove and tongue portions are spaced below the top of the guide beam a distance sufficient, to permit the joint to be sealed while maintaining the joint, including sealing portions thereof, isolated from the top of the guide beam and from a bearing positioned on the guide beam. The tongue and groove portions together define a sealing space for receiving a flexible sealant to seal the joint. Sealant oozing out of the sealing space into the space above the joint is isolated from the bearing. The joint may also be secured by a weld bead in the space above the joint. A layer of flexible sealant may be placed on top of the bead. Both the bead and the sealant are isolated from the bearing.

Abstract: A reciprocating conveyor floor slat has an upper portion with an upper surface and at least one longitudinally extending ridge projecting upwardly from the upper surface. The ridge has a longitudinally extending pointed top portion positioned to engage a bottom surface of an article placed on the slat. The pointed top portion is spaced above the top surface a distance sufficient to maintain the bottom surface of the article out of contact with the slat's upper surface as the article is being conveyed. The preferred number of ridges per slat is two, with the ridges projecting upwardly from laterally opposite portions of the upper surface. Preferably, the bottom surface of the article being conveyed remains at least about 90% out of contact with the slat. When articles such as wooden pallets are conveyed, the pointed top portions of the ridges dig into the bottom surfaces of the pallets to form longitudinal grooves to guide longitudinal movement of the pallets. The low percentage of the area of the bottom surface that contacts the slats minimizes the likelihood of the bottom surface hanging up on the slats.
