Abstract: Two series of work products move along parallel paths into open bags mounted on wickets and carry the bags to shipping containers. When the bags on the wickets are depleted, the wickets are automatically removed and replaced by wickets loaded with a new supply of bags.

Abstract: End of arm tool (10) is used to load goods A and B in two layers in a packing container (8), with a packing insert positioned between the layers. The tool (10) also grasps a packing insert in the form of a flat sheet, bends the ends of the packing sheet downwardly to form an inverted U shape, and then inserts the packing insert in a straddling relationship about the lower layer of goods A, to protect the lower layer of goods from the weight applied by the upper layer of goods B.

Abstract: A bellows 10 is configured for connection to an end effector of a robot and includes a valve 28 supported in the interior space of the bellows. A flow of low pressure air is induced from inside the bellows into a vacuum plenum 24 for retrieving a work product by the open end 16 of the bellows. High pressure air is moved through a conduit 50 into the valve to terminate the flow of low pressure air and terminate the suction applied by the bellows to the work product.

Abstract: A valve 28 is positioned in the upper portion of the interior space of the bellows 10. A flow of low pressure air is induced inside the bellows when the valve elements 40 move away from the air inlet openings 38. When high pressure air is moved into the central portion of the valve housing 30, the valve elements 40 tend to move radially outwardly to block the air passages 38 and 42, thereby terminating the suction applied to the bellows.

Abstract: Cable manager 30 is positioned between the distal end of a robot arm 16 and the robot end effector 18. Elongated cable carrier 44 positioned in a circular cable track 34 extends in an arc about the axis of connection 17 between the robot arm and the end effector. One end 56 of the cable carrier moves with the robot arm and the other end 54 moves with the end effector. The cable carrier forms a U-shape 60 between its ends so that the movements of the ends of the cable carrier result in the U-shape accommodating the change in distance between the ends of the utility line and the cable carrier. Utility lines 62 are gathered in one or more cables that extend through the cable carrier to provide the end effector with the controls necessary for its operation.

Abstract: An air retriever, such as a bellows (24) is used in an end effector (18) for lifting work products (22) in prearranged configurations, and delivery to a container (20) in a predetermined pattern. An air flow control valve (50) is positioned in each bellows (24) for individually controlling the flow of air through each bellows so that the bellows in a pick zone may draw air for picking up work products while air flow is not applied to the other bellows out of the pick zone.

Abstract: A metering system for handling product through a packaging operation comprising: a mechanism for transporting individual product units in discrete lanes to a staging area ahead of a subsequent processing operation; a stop for restraining the flow of product before it enters the subsequent processing operation; a mechanism for detecting when a predetermined quantity of product has accumulated in each lane of the staging area against the stop; and a mechanism for restraining by individual lane further quantities of product before they enter the staging area.

Abstract: A combination sealing and cutting device comprising: an elongated anvil having an elongated slot therein; an elongated blade having a longitudinal aperture therein; a heating element in the longitudinal aperture; and an actuator mechanism for driving the blade toward and into the elongated slot to accomplish simultaneous sealing and cutting of overlying polymer films. According to various preferred embodiments, the combination sealing and cutting device further includes a pair of parallel flanges extending along both edges of the blade that serve to retain the blade; and film retaining beads along the longitudinal edges of the parallel flanges that serve to retain the plastic films being cut and sealed against the outer edges of the elongated slot.

Abstract: An adjustable lane guide system comprising: 1) first and second generally parallel and spaced apart support bars; 2) a plurality of lane guides generally perpendicular to the support bars; and 3) a plurality of adjustable attachment mechanisms joining the lane guides to the first and second support bars. Each of the adjustable attachment mechanisms comprises a bearing block that engages the support bars; a pair of opposing wings on either side of the bearing block also engaging the support bars and each having first and second ends, the first ends hingeably attached to the bearing block and the second ends flared by a spring located between the pair of opposed wings such that pressure applied to each of the second ends causes the wings to be drawn toward each other against the pressure of the spring thereby allowing the adjustment mechanisms to move laterally along the support bar so that the distance between adjacent lane guides can be changed along the first and second support bars.

Abstract: A splicing device comprising: an elongated anvil having an elongated slot therein; an elongated splicing head having a pair of spaced apart tips extending therefrom and having a longitudinal aperture therein; a heating element in the longitudinal aperture; and an actuator mechanism for driving one of the tips toward and into the elongated slot to weld two overlying polymer films together and the other of the tips into cutting contact with a polymeric film from a spent roll of film. According to various preferred embodiments, the splicing device further includes a pair of retaining members on either side of the anvil that serve to retain films to be spliced in taut contact with the anvil during splicing, and a turret section for rotating full and spent rolls of polymeric film into position for continued operation and reloading.

Abstract: In collating packaging equipment and the like, a novel flight that comprises a flight body including at least one spring loaded arm that engages the conveyor drive chain to allow rapid and simplified interchangeability of flight arrangements, i.e. pitch or pocket size, without the need for disassembly and re-assembly of the entire flight drive mechanism.

Abstract: A two axis, two drive mechanism, two belt design Cartesian robot wherein each axis is independently controlled and all applied forces are along the centerline of the robot structure. This unique design allows for the use of a low cost control system since a so-called “multi-axis motion controller” is not required. Co-location of the drive systems allows support of the robot from one end. Centering of forces acting on a carriage assembly allows for the reduction of the weight of the robot for a given payload.
