Trolley apparatus for unloading and supporting heavy coils of wound filament material from a winding machine to a packaging table

摘要

A trolley for moving heavy objects such as wire coils from a machine to a container at a packaging table is provided. The trolley includes spring-loaded spaced arms movably mounted for vertical height adjustment so that the arms are just below the coil when it is on the machine and rotational movement to separate the spaced arms with the spaced arms retaining the heavy object during movement of the trolley apparatus, and locking arms engaging the spaced arms during movement of the trolley apparatus to prevent separation thereof. The spring-loaded arms permit the heavy object to be manually pushed downward therebetween, thereby forcing the arms apart enabling the object to fall from the trolley into a container on a packaging table. The table includes a platform for supporting the container, a motor for raising/lowering the platform, and a mechanism for retaining the container and aiding its alignment with the coil.

主权项

1. A trolley apparatus for moving heavy objects from a machine to a container at a packaging table station, comprising:
a wheeled base constructed for movement of said trolley apparatus on a floor; a plurality of spaced arms coupled to said base, the arms constructed for vertical translational and rotational movement with respect to said base, wherein said arms rotate to adjust the relative spacing between said arms, and wherein said arms are configured to retain the object between said spaced arms during movement of said trolley apparatus; and locking arms coupled to said base for selectively engaging said spaced arms and for limiting further outward rotation of said spaced arms when the locking arms are engaged with said spaced arms; wherein said locking arms are constructed to disengage from the spaced arms and permit said spaced arms to rotate into a dispensing position in response to a force applied to the spaced arms that is at least a predetermined force, wherein in said dispensing position said spacing between said spaced arms increases to a size sufficient for the object to pass through said spacing.
