Definitions

  • the object of the invention is to provide a constant supply of material to a processing apparatus or subsequent treatment station through the use of a single box device.
  • Another object of the invention is to provide a supply box device wherein the material being treated is introduced into the box device over only part of the length of the box.
  • a further object of the invention is to provide equalizing devices in the box device so that the depth of the Patented Sept. 15 1970 "ice piled up material can be controlled over the length of the box which is not being subjected to the introduction of material from an initial source.
  • the supply device of this invention provides an absolutely uniform output amount of material at its removal or combing out point.
  • the constant supply of material is then ready for further processing.
  • the material to be treated is initially introduced into the box device over only part of its overall length.
  • the floor belt of the box device conveys the material at the greatest filling depth along part of the overall length before it reaches the removal point of the box device.
  • Elements provided in the box device work on the material at its greatest filling depth to insure uniform height of the material in the box before it reaches the removal point.
  • the maintaining of a uniform height over a specific length of the floor belt as it moves toward the removal point insures a constant and uniform removal of the material as it is carried off the end of the belt.
  • the height of the material on the floor belt is controlled through the use of members provided at the top of the box device for the purpose of equally distributing the material as it passes along the floor belt toward the removal point of the box device.
  • These members may include stationary or movable combs or rotating wheel crosses distributed over the length of the box not being subjected to the introduction of material from the source device.
  • These comb members or wheel cross members are adjustable in a vertical direction so that the height of the material may be controlled in the box device as it passes over the floor belt just before the removal point in the box device.
  • the elimination of a weighing step would necessarily increase the efficiency by not requiring an additional, time wasting weighing stage for a completed bale.
  • the uniformity of the pressing operation made possible through the use of such a constant and uniform device supplying system would necessarily eliminate any adjustment in the adaptation of the treatment process to a varying amount of material.
  • the particular box device supply system provides a constant supply to the treatment process through the use of only one box whereas any constant supply system heretofore has required the use of two boxes as discussed herein above.
  • the material being introduced into the box device is obtained from a source supply which extends only over about two-thirds to three-quarters of the box length or the floor belt.
  • a layer by layer filling of the introduced material can be advantageously effected through the use of a mixing belt.
  • the belt which is well known in the art has the ability to reverse its motion and belt direction as it reaches the end position of its cycle. The cycle of the mixing belt is adjusted so that it will move over the desired portion of the box device length as indicated above.
  • Another method of introducing material onto the floor belt could be through the use of a pivoting funnel provided over the desired portion of the box device.
  • the single illustration shows the formation of a box device according to the invention, in schematic longitudinal section.
  • the box device generally designated as 1, has a floor belt 2 which runs over the rollers 3 and 4 in the direction of arrow 5.
  • a motor 6 drives the forward roller 3.
  • the source of material which is introduced into the box device is located at a stationary delivery point 18.
  • the material is loaded onto a rotary belt 7, 8, 9 which moves back and forth in the direction of motion 10.
  • the material is thrown once over roller 8 or 9 depending upon the direction of travel of the belt and its location at the time the material is loaded onto it.
  • the operation of such a mixing belt 7, 8, 9 is well known in the prior art and its adaptation to the invention as disclosed in this process is within the ordinary skill of the art.
  • the normal movement of the mixing belt 7, 8, 9 is over the entire length of the floor belt 2.
  • the mixing belt 7, 8, 9 moves only over part of the floor belt 2 in the box device of the instant invention.
  • One or more devices for controlling the height of the material being piled on the floor belt 2 can be mounted on the box device 1 in the direction of the removal end 14.
  • a wheel-cross constitutes the control device which is rotatable in the direction of arrow 12.
  • the operation of such a control device such as the Wheel-cross 11 effects a combing ofi of the pile 13 which is being controlled at a predetermined height.
  • the operation of the wheel-cross in this manner controls the height of the'material at a constant value on the removal side 14 of the pile 13. This control of the height at a constant value is effective in spite of the simultaneous addition of material from the source of the rotary belt 7, 8, 9.
  • One or more rotary removal devices 15 which are movable in a vertical direction, are located at the removal end 14 of the pile 13. As the material is removed from the pile 13, it falls downwardly toward a funnel 17 to supply a further processing machine not shown.
  • a beater cross 16 located at the lower end of the removal space 14 operates to loosen up any material removed from the pile 13 as it falls toward the funnel 17.
  • equalizing devices such as the wheel-cross 11 is necessary for the purpose of maintaining a constant height where the material undergoes great variations while on the floor belt 2.
  • a box device for providing a constant uniform supply of material for subsequent treatment comprising:
  • a movable belt means having a material introduction portion, a material height adjustment portion, and a removal end;
  • said supplying means includes a reciprocating, re-
  • control means includes at least one equalizing device operating over the adjustment portion of the belt
  • said removal means includes a rotatable, vertically movable device operating at the removal end before said loosening means.
  • control means includes height adjustable swinging combs operating to equalize the height of the material in said adjustable portion.
  • control means includes at least one wheel-cross.
  • control means includes at least one comb-roller.
  • said supplying means includes a stationary delivery point located at the introduction portion of said belt, and
  • said mixing belt is located between said delivery point and said continuous belt.
  • said loosening means includes a beater cross disposed at the end of said belt means.
  • control means includes height adjustable swinging combs operating to equalize the height of the material in said adjustment portion.
  • control means includes at least one wheel-cross.
  • control means includes at least one comb-roller.
