A transfer has gripper bars capable of grasping, lifting and transferring a work piece. The grasping and lifting motions are actuated by face cams. The face cams act through rocker arm linkages connected to rotatable rods having arms connected to the gripper bars. The transferring motion is actuated by a barrel cam having an axial cam curve positioned between cam followers. A lifting frame has diagonal slots which receive guide pins connected to a base frame. A rack and pinion assembly connected to the gripper bars facilitates the gripping motion. Slidably mounted blocks with toothed wheels supporting arms of various radial extension provide variable travel distances for the gripper bar when moving in the transfer direction.

Disclosed is a method and apparatus for loading articles, particularly meat articles, into containers. The apparatus comprises two groups of movably mounted beams cantilevered in a direction of article progression. One group of beams is movable in a vertical direction while the other group of beams is movable in a horizontal direction. The movement of the beams is synchronized to provide for article movement in the desired direction. The terminal portions of both sets of beams are unconnected and spaced apart so as to provide a spaced relationship between the group of beams to permit the insertion of a container over the terminal portions of the beams.

Compact, lightweight transport apparatus for use particularly in hostile environments employs a plurality of groups of rails flexurally mounted to a base and corresponding groups of slats flexurally mounted to the rails and forming a slat array. Corresponding groups of slats and rails are reciprocated out of phase so that the slat group orbits relative to the base along an orbital path. The different slat-rail groups are also reciprocated out of phase with one another so that an object placed on the slat array is advanced incrementally along the slat array in a very gentle fashion.

An elongated conveying device suitable for connecting spaced work stations, for example, receives a flow of objects such as component parts at an appropriate entrance. The objects are placed on a pair of spaced stationary rails from which the objects are lifted, carried forward and then returned to the stationary rails by a pair of movable rails which is rotated in a circular-shaped cycle. With each cycle of the movable rails, the objects are stepped from the entrance to an exit located some distance away. Because the rate of object input may vary from the rate of part discharge, the conveying device may include holding stations adjacent to the exit allowing the objects to accumulate in a damage resistant manner until removed from the conveying device.

A device for displacing elongated bodies transversely to their axes comprises at least two parallel and horizontal supporting bars of circular cross section, lying in the same plane and having each a longitudinal, outwardly open groove which houses a slide of which the cross section corresponds to that of the groove and has a part inscribed in the circumference of the bar section. Means are provided for slightly rotating the bars about their axes for longitudinally displacing the slides within the grooves. The elongated body to be displaced is placed on the bars so as to rest on the slides which are then moved to displace the body; afterwards, the bars are rotated so that the body is no longer in contact with the slides, which can be moved back to the initial position.

A mechanism is provided for advancing articles step by step between work stations of a press. The mechanism includes a pair of bracket assemblies mounted on opposite sides of the press frame and provided with feed bar support assemblies including members supporting a pair of parallel feed bar-feed finger members for longitudinal and lateral reciprocation to achieve article transfer. The bracket assembly includes a first portion fixed on the press frame and a second portion which carries the corresponding feed bar support assembly and which is pivotal relative to the first bracket portion between use and non-use positions. The drive arrangement for the reciprocable feed bar support members includes portions pivotal with the second bracket portion. The feed bar-feed finger members are detachable, thus enabling the second bracket portions and corresponding portions of the drive arrangements to be pivoted to the non-use position to facilitate access to the press. A plurality of such article feed mechanisms are adapted to be associated with the press and driven in unison by common drive belts and shafts on each of the opposite sides of the press.
摘要:
Pipe handling apparatus for pipe laying barges, sometime called lay barges, wherein pipe is lifted from an incoming pipe conveyor to a transverse rack, from one rack position to another, and from the rack to the pipe line-up conveyors, by a series of pivotal lifting means which lift, move, and deposit the pipe without impact or shock, whereby the pipe and any concrete or other coating on the pipe is not damaged. In addition to the novel pipe transferring means, the invention presents a novel universally adjustable line-up conveyor apparatus.

A workpiece transfer mechanism having a walking beam carried by a slide mounted for reciprocal movement on a bed or table. A particular bell crank linkage is provided so that a single hydraulic cylinder both raises and lowers the walking beam with respect to the slide and also moves the slide longitudinally with respect to the table. The table is carried by a second slide for reciprocation of the table by a second hydraulic cylinder.

摘要:
A transfer beam conveyor comprises a first elongated support structure, a second elongated support structure, an arrangement for mounting the first structure at a stationary position with respect to the length of the conveyor, and an arrangement for mounting the second structure for longitudinal movement relative to the conveyor and to the first structure. A mechanism is provided for reciprocating the second structure longitudinally of the first structure, together with mechanism for elevating each of the support structures so that a number of loads can be indexed therealong at essentially constant elevation.
