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

Abstract

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.

1 . Trolley apparatus for moving heavy objects from a machine to a container at a packaging table station, comprising:
 a wheeled trolley apparatus having spaced arms movably mounted thereon for vertical height adjustment so that the arms are just below the coil when it is on the winding machine and rotational movement to separate the spaced arms; and spaced arms for retaining said heavy object during movement of the trolley apparatus;   said heavy object being manually slid onto said spaced arms for wheeled movement of the trolley apparatus and the heavy object from said machine to said coil packaging table station;   locking arms engaging said spaced arms during movement of said trolley apparatus to prevent separation of the spaced arms; and   said heavy object being manually pushed downward between the arms of said trolley apparatus forcing the spaced arms apart enabling the heavy object to fall from the trolley apparatus into the container through the separated spaced arms.   
     
     
         2 . A trolley apparatus as claimed in  claim 1  wherein said spaced arms are supported by said trolley apparatus at a distance from the floor supporting said trolley apparatus that is convenient for the operator of said trolley apparatus to manually slide the heavy coils onto said spaced arms and to manually push said heavy object through said spaced arms at the packaging table. 
     
     
         3 . A trolley apparatus as claimed in  claim 1  where said heavy object is a heavy wound coil from a coil winding machine and the heavy wound coil is deposited in said container at said packaging table. 
     
     
         4 . A trolley apparatus as claimed in  claim 2  where said heavy object is a heavy wound coil from a coil winding machine and the heavy wound coil is deposited in said container at said packaging table. 
     
     
         5 . A packaging table for retaining a container to receive heavy objects transported by a trolley apparatus, comprising:
 a platform for supporting the container and movable in a vertical direction;   said packaging table including a motor for raising or lowering said platform;   said platform including means for retaining said container to prevent slippage from the platform and aid in alignment of said heavy coil and the packaging continer; and   a pair of foot-operated switches, one of said switches activating said motor to raise said platform and the other of said switches activating said motor to lower said platform.   
     
     
         6 . A packaging table as claimed in  claim 5  further comprising: a pair of limit switches for controlling the lower and upper movement of said platform. 
     
     
         7 . A trolley apparatus as claimed in  claim 1  further comprising a packaging table for retaining a container to receive heavy objects transported by a trolley apparatus, comprising:
 a platform for supporting the container and movable in a vertical direction; 
 said packaging table including a motor for raising or lowering said platform; 
 said platform including means for retaining said container to prevent slippage from the platform and aid in alignment of said heavy coil and the packaging continer; and 
 a pair of foot-operated switches, one of said switches activating said motor to raise said platform and the other of said switches activating said motor to lower said platform.
