Abstract
A baling press has a horizontal construction, for compaction of loose material, a pressing channel having a fill-in opening, a pressing plate that can be displaced in the pressing channel, a pressing surface that stands in contact with the material to be compacted, multiple hydraulic cylinders coupled with electro-hydraulic drive assemblies for generating a pressing force, for advancing the pressing plate for the purpose of introducing the pressing force into the filled-in material, as well as for returning the pressing plate to a starting position, and a control and regulation system configured for monitoring the spatial orientation of the pressing surface and keeping it constant during the advancing movement of the pressing plate.
Claims9
A baling press (1;
- 11;
- 12) for compaction of loose material (M) comprising:
- a pressing channel (3) having a fill-in opening (4) for the loose material (M),
- a pressing plate (5) that can be displaced in the pressing channel (3) over a predetermined pressing path length (Lges),
- multiple hydraulic cylinders (H11 . . . Hn;
- H21 . . . Hn) coupled with drive assemblies (A1, A2, A3, A4),
- for generating a pressing force,
- for advancing the pressing plate (5) over the predetermined pressing path length (Lges) for the purpose of introducing the pressing force into a filled-in portion of the loose material (M), and
- for returning the pressing plate (5) to a starting position,
- wherein the baling press further comprises a control and regulation system configured for monitoring a spatial orientation of a pressing surface (6) of the pressing plate and keeping it constant during the advancing movement of the pressing plate (5) over the pressing path length (Lges),
- wherein the multiple hydraulic cylinders are switched in parallel, by groups,
- wherein a first group (H1) of the multiple hydraulic cylinders (H11, H12 . . . Hn) switched in parallel is provided for generating the pressing force and transferring it to a displaceable intermediate plate (9), and
- wherein a second group (H2) of the multiple hydraulic cylinders (H21, H22 . . . Hn) switched in parallel is provided for generating the pressing force and transferring it to the pressing plate (5), so that the pressing plate (5) can be displaced relative to the intermediate plate (9) by means of the multiple hydraulic cylinders (H21, H22 . . . H2n).
