专利汇可以提供Machine for conditioning waste material for recycling专利检索,专利查询,专利分析的服务。并且A machine which bales waste material to condition it for recycling and thus helps alleviate waste disposal problems which lead to pollution. The machine includes a ram which reciprocates to compact waste material in a container and ultimately eject the waste material in the form of a bale. The resistance of the compacted material to the ram is sensed to reverse the ram automatically. In an automatic mode, the ram keeps reciprocating and compacting as long as the input of the machine is loaded until a full bale is formed and ejected. Excess waste material at the input is sheared off. A manipulator is disclosed which facilitates binding of the compacted waste into a bale. Drive means and control means are disclosed. The ram can move all the way to the discharge end of the container or any compacting position short of the discharge end to give uniformity of compaction. The bale weight is fully adjustable.,下面是Machine for conditioning waste material for recycling专利的具体信息内容。

1. A machine for conditioning waste for recycling comprising a container, a reciprocative ram in said container, said ram being movable back and forth between first and second positions adjacent to first and second end portions of said container, closure means for said second end of said container movable between open and closed positions, means to releasably latch said closure means, feeding means to feed waste material into said container between said first and second positions, drive means to reciprocate said ram, said drive means including a reversible electric motor and means coupling said motor to said ram, control means for said motor operative to actuate said motor for reciprocating said ram forward from said first position toward said second position and then backward toward said first position, the forward motion of said ram serving in operation to compact waste material against said closure means and ultimately to eject the compacted waste when said closure means is opened, said control means including sensing means responsive to the action of said ram and said drive means to switch said control means from forward mode to reverse mode and from reverse mode to forward mode, and means for binding the compacted waste in said container before ejection thereof, said binding means including retainer means at one side of said container between said end portions thereof, and plunger means movable across said container from a side thereof opposite said one side, said plunger means being operable to place a binding strand in said retainer means and remove the same from said retainer means.
2. The machine as claimed in claim 1 in which said sensing means includes a current responsive element in circuit with said motor operative to change said control means from the forward mode to the reverse mode when the motor current exceeds a threshold level.
3. The machine as claimed in claim 2 in which said sensing means further includes first and second limit switch means for said first and second end portions of said container respectively, with said first limit switch means being operative by said ram to change said control means from the reverse mode to the forward mode and said second limit switch means being operative by said ram to change said control means from the forward mode to the reverse mode.
4. The machine as claimed in claim 1 in which said coupling means between said motor and said ram includes at least one drive screw.
5. The machine as claimed in claim 1 in which said plunger means has a flat end portion with slotted edges to receive a loop of said strand and to release and recapture the same.
6. The machine as claimed in claim 1 in which said feeding means includes a hopper communicating into said container.
7. The machine as claimed in claim 6 including photocell means for said hopper to sense when said hopper is full.
8. The machine as claimed in claim 6 in which said feeding means further includes a knife edge at a trailing side of the junction of said hopper and said container having a shearing action with said ram.
9. The machine as claimed in claim 8 including door means actuated by said ram to close said junction when said ram moves forward.
10. The machine as claimed in claim 8 in which said ram has a further knife edge to shear with the knife edge of claIm 8 for shearing off waste material extending from said container through said junction toward said hopper.
