Abstract
The scale rail of a weighing mechanism is interposed in axial alignment with the spaced adjacent ends of an elevated fixed trolley rail, and means are provided for advancing a wheeled trolley onto the scale rail after which the initial trolley-advancing means is physically disengaged from the trolley thereby permitting it to stop on the scale rail where it remains until the trolley is next engaged by second trolley advancing means which advance it along and off of the scale rail onto an adjacent section of the trolley rail. Means are provided for selectively disposing the second trolley advancing means in operative or in inoperative relationship relative to a trolley.
Claims11
A static weighing-on conveyor comprising:
- an elevated trolley rail,
- a scale rail interposed between spaced, adjacent ends of the trolley rail,
- an endless conveyor chain,
- means supporting portions of said chain at lower, upper and inclined transition levels between said lower and upper levels,
- means imparting movement of the chain along and relative to said supporting means,
- a plurality of alternately short and long drop fingers pivotally secured to, carried by, spaced along and depending from said chain,
- a wheeled trolley supported on and selectively movable over the trolley and scale rails by first a short drop finger and then by the next succeeding long drop finger,
- the said lower level of the chain disposing the short drop fingers in contacting engagement with an upper portion of a trolley and wherein said fingers are automatically and progressively disengaged from a trolley as the chain passes upwardly along the inclined transition level as the trolley is advanced from one end of the trolley rail onto the scale rail,
- the said transition and upper levels of the chain disposing the long drop fingers in contacting engagement with that upper portion of a trolley which was disengaged by a preceding short drop finger for advancing a trolley from the scale rail onto the other end of and thence along the trolley rail.
A static weighing-on conveyor comprising:
- an elevated trolley rail,
- a scale rail interposed between spaced, adjacent ends of the trolley rail,
- an endless conveyor chain,
- means supporting certain portions of said chain at a lower level which is located above and in substantial spaced parallelism with that portion of the trolley rail which is in advance of the scale rail;
- said means supporting other portions of the chain at an upper level which is higher above said trolley rail than the elevation of said first level with respect to the trolley rail and in substantial parallelism with that portion of the trolley rail which is to the rear of the scale rail;
- said means supporting still other portions of the chain along an upwardly inclined transition level which spans the adjacent ends of the scale and trolley rails between said lower and upper levels, wherein said transition level terminates at the upper level above and intermediate the length of the scale rail;
- and
- A plurality of alternately long and short drop fingers pivotally secured to, carried by, spaced along, and depending from said chain.
