Abstract
A drive apparatus for a cable conveyor system having a channel formed adjacent to a drive wheel for receiving a partial loop of excess cable for the purpose of preventing the cable from becoming too tight or too loose for the proper functioning of the system. A switch assembly is positioned adjacent to one end of the channel for sensing an enlarged partial loop of cable and shutting off the power to the drive apparatus in response to such condition.
Claims16
A drive apparatus for a cable conveyor system comprising:
- a housing;
- drive wheel means rotatably attached to said housing;
- a continuous cable having a plurality of spaced members rigidly attached thereto, a portion of said cable being disposed around one side of said drive wheel means, said drive wheel means engaging said cable for pulling said cable through said cable conveyor system, said one side of the drive wheel means being defined as the portion of said drive means having said cable in contact therewith at all times;
- and
- channel means attached to said housing for receiving and guiding a partial loop of excess cable and for allowing movement of said partial loop due to a change in size of said partial loop from a point in which an intermediate part of said partial loop is in contact with the other side of said drive wheel means to a point in which said intermediate part is spaced a substantial distance from said drive wheel means whereby said channel means comprises the sole support for said partial loop, said partial loop of excess cable extending from the point at which said cable departs contact with said drive wheel means to a point at which said cable departs said channel means.
