Abstract
A conveyor arrangement for moving steel slabs on motor driven rollers includes a stop assembly which is positionable in the path of movement of the slabs for preventing further movement. The shock of the moving slab against the stop plate is absorbed by a plurality of spherical elastomeric cushion members positioned to achieve maximum cushioning efficiency.
Claims25
In a conveyor arrangement having a plurality of horizontally spaced conveyor members adapted to support and convey products in a horizontal direction, the improvement of a stop mechanism for stopping the movement of said products comprising:
- a stop element supported on said arrangement for movement to a blocking position blocking movement of said product,
- means associated with said stop element for moving the same between blocking and non-blocking positions,
- a shock absorbing means including first spherical elastic means supported on said arrangement on one side of said stop element,
- second spherical elastic means supported on said arrangement on the other side of said stop element,
- means operatively associated with the stop element and providing for diagonal tilting of the stop element, and
- whereby said first and second elastic means engage and guide opposite sides of said stop element during said movement of said stop element to the blocking position and whereby during blocking of said products said stop element is tilted diagonally and the shock forces are absorbed by said spherical elastic means.
In a conveyor arrangement having a plurality of horizontally spaced conveyor members adapted to support and convey products in a horizontal direction, the improvement of a stop mechanism for stopping the movement of said products comprising:
- a stop element supported on said arrangement for movement to a blocking position blocking movement of said product,
- means associated with said stop element for moving the same between blocking and non-blocking positions,
- a shock absorbing means including first spherical elastic means supported on said arrangement on one side of said stop element, and
- second spherical elastic means supported on said arrangement on the other side of said stop element,
- whereby said first and second elastic means engage and guide opposite sides of said stop element during said movement of said stop element to the blocking position and whereby during blocking of said products said stop element is tilted diagonally and the shock forces are absorbed by said spherical elastic means,
- said spherical elastic means comprising a first row of elastic springs supported on said arrangement and engageable with a first side of said stop element intermediate opposite vertical ends thereof, and
- a second row of elastic springs supported on said arrangement and engageable with an opposite second side of said stop element adjacent a lower end thereof.
For a conveyor arrangement having a plurality of horizontally spaced conveyor members adapted to support and convey products in a horizontal direction, an improved stop mechanism for stopping the movement of said products comprising:
- a stop element mounted on said arrangement vertically movable between a first blocking position for stopping the movement of said products and a second non-blocking position,
- actuating means for moving said stop element between said blocking and non-blocking positions, and
- shock absorbing means in the arrangement engaging said stop element comprising elastromeric shock absorbers,
- means operatively associated with the stop element and providing for horizontal displacement of the stop element upon impact thereof by the products,
- whereby blocking of said products by said stop element horizontally displaces the upper portion of said stop element transmitting shock forces thereby generated to said shock absorbing means.
For a conveyor arrangement having a plurality of horizontally spaced conveyor members adapted to support and convey products in a horizontal direction, an improved stop mechanism for stopping the movement of said products comprising:
- a stop element mounted on said arrangement vertically movable between a first blocking position for stopping the movement of said products and a second non-blocking position,
- actuating means for moving said stop element between said blocking and non-blocking positions, and
- shock absorbing means in the arrangement engaging said stop element comprising horizontally spaced elastomeric shock absorbers disposed on opposite sides of said stop element,
- means operatively associated with the stop element and providing for horizontal displacement of the stop element upon impact thereof by the products,
- whereby blocking of said products by said stop element horizontally displaces the upper portion of said stop element transmitting shock forces thereby generated to said shock absorbing means.
For a conveyor arrangement having a plurality of horizontally spaced conveyor members adapted to support and convey products in a horizontal direction, an improved stop mechanism for stopping the movement of said products comprising:
- a stop element mounted on said arrangement vertically movable between a first blocking position for stopping the movement of said products and a second non-blocking position,
- actuating means for moving said stop element between said blocking and non-blocking positions, and
- shock absorbing means in the arrangement disposed on opposite sides of said stop element engaging said stop element,
- said shock absorbing means comprising a first shock absorber engaging the lower portion of one side of said element, and
- a second shock absorber engaging the opposite side of said stop element intermediate of said first shock absorber and the top of said stop element,
- means operatively associated with the stop element and providing for horizontal displacement of the stop element upon impact thereof by the products,
- whereby blocking of said products by said stop element horizontally displaces the upper portion of said stop element transmitting shock forces thereby generated to said shock absorbing means.
