Abstract
A horizontal baling apparatus having a compression ram which is provided so as to be reciprocally movable into the baling chamber of the apparatus, and a mechanism which scales the length of stroke of the compression ram to a total stroke of a potentiometer, from the output of which the density of a portion of a bale of material is determined as well as the necessary amount of additional material which is required on successive laminations to maintain the density.
Claims13
A horizontal apparatus for baling compressible material of unknown density, comprising:
- a body member defining a baling chamber at one end thereof, and having a hollow longitudinal section adjacent to said baling chamber, said hollow section having a material inlet therein;
- bale compression means including a compression ram provided in said hollow inlet section for reciprocal movement therein, so as to form laminations of the compressible material in said baling chamber;
- a drive cylinder for moving said ram;
- means for determining the density of the feed stock during compression of a lamination of the material on completion of a compression stroke;
- and
- means for calculating the amount of material required to be fed on successive compression strokes based on the determined density of feed stock, so that a desired number of additional laminations can be formed to complete a bale of desired density.

- bale compression means including a compression ram provided in said hollow inlet section for reciprocal movement therein, so as to form laminations of the compressible material in said baling chamber;
- a drive cylinder for moving said ram;
- means for determining the density of the feed stock during compression of a lamination of the material on completion of a compression stroke, said density determining means including means for sensing the pressure exerted by said compression ram on the scrap material, and means for measuring the travel of said compression ram, the density of the feed stock being computed as a function of the distance travelled by said compression ram and the pressure exerted by said compression ram, said travel measuring means including a linear potentiometer having a stroke length, a first rack mounted on said cylinder so as to be movable therewith, a second rack provided on a carrier member so as to be approximately parallel with said first rack, said carrier member being connected to said potentiometer, and a pinion shaft having a gear on each end thereof, and being provided between said first and said second racks so that one of said gears engages with each of said racks, said gears having a variable gear ratio which allows the length of the cylinder stroke to be scaled to the stroke length of said potentiometer;
- and
- means for calculating the amount of material required to be fed on successive compression strokes based on the determined density of feed stock, so that a desired number of additional laminations can be formed to complete a bale.
