Definitions

  • the present invention relates to a bale press and a method for compressing waste material into bales, e.g. return paper, cardboard boxes or similar bulky goods.
  • a previously known bale press comprises a prepress and a main press.
  • An inlet opening opens into a prepress chamber.
  • a precompressing of the goods takes place into a main press chamber.
  • the filling and precompressing can be repeated until sufficient material has been precompressed into the main press chamber.
  • the prepress stops in its bottom position and the main press is activated for compressing the material into a bale, which is expelled through a channel, whereupon a new filling, precompressing and maincompres- sing takes place until a predetermined bale length has been achieved, whereupon baling takes place.
  • the bales are successively fed out from the channel.
  • Such a previously known bale is shown in US-A-4 121 515 which disclosed an apparatus for baling unshredded material comprising: a charging inlet for receiving loose material; a baling chamber into which material is delivered from said inlet; a discharge outlet from said bailing chamber; a first reciprocal baling head adapted to move toward and away from a fixed sidewall between a retracted position for receiving loose material through said inlet and an advanced position spaced from said fixed sidewall; means for reciprocating said first baling head for precompression; a second reciprocable baling head adapted to move in a direction generally perpendicular to the direction of movement of said first baling head between a retracted position for receiving loose material and an advanced position for compacting material into said outlet; and means for reciprocating said second baling head for main compression.
  • GB-A-1 360 215 Another such a previously known bale press is shown in GB-A-1 360 215, which discloses a bale press having precompaction and main compression.
  • a precompaction chamber When a precompaction chamber is filled with material to be baled, two lid plates are swung from an open position to a closed position for defining a baling chamber.
  • bale press In some applications it is desirable to have a wider inlet opening in order to be able to accommodate larger empty boxes and similar. If the above-mentioned bale press was constructed having a wider inlet opening, at least the prepress would have to be proportionally enlarged and the total bale press would be too bulky for many applications. The other way round, the present bale press is already too big for certain applications, and thus there is a need for a small but efficient bale press.
  • the object of the present invention is to provide a bale press of the type disclosed in US-A-4121 515 where it is possible to use a wider inlet opening or alternatively the machine size can be diminished.
  • the precompression takes place in two steps, a first precompression in the horizontal direction and a subsequent precompression down into the main press chamber. After the first precompression, further material can be loaded before the second precompression takes place down into the main chamber.
  • a bale press for compressing bulky goods into bales, comprising an inlet section, a prepress chamber and a main press chamber, whereby a main press plunger is adapted to perform a main compression of the goods into a bale
  • the prepress chamber contains a prepress unit with at least one forward wall reciprocable between a retracted position essentially leaving the prepress chamber free and an extended position in which the forward wall substantially decreases the volume of the prepress chamber, characterised in that the prepress unit is quadrantal in cross-section and is pivotable around an axis positioned on a carriage between a first position in which the forward wall of the prepress unit is essentially vertical, to a second position in which the forward wall of the prepress unit is essentially horizontal in order to provide a second precompression of the goods from the prepress chamber to the main press chamber.
  • the movements of the bale press are imparted by means of hydraulic cylinder units, and the carriage is guided on horizontal rails.
  • a method of compressing bulky goods into bales in a bale press comprising an inlet section, a prepress chamber and a main press chamber, including the step of compressing the goods in the main compression chamber into a bale by means of a main press plunger, a first precompression by reciprocating a prepress unit having at least one forward wall, from a retracted position to an extended position in which the forward wall substantially decreases the volume of the prepress chamber, characterised by pivoting the prepress unit, which is quadrantal in cross-section and is pivotable around an axis positioned on a carriage, from a first position in which the forward wall is essentially vertical, to a second position in which the forward wall is essentially horizontal thereby providing a second precompression of the goods from the prepress chamber to the main press chamber.
  • Fig. 1 is a longitudinal side view with the side plate removed of the bale press according to the invention in the start position or load position
  • Fig. 2 is a similar side view of the bale press according to Fig. 1 after the horizontal compress operation.
  • the bale press is shown in a longitudinal side view in Fig. 1 with the side plate removed.
  • the bale press comprises an inlet section 2, a prepress chamber 3 and a main press chamber 4.
  • the inlet section 2 is intended to be loaded from above.
  • a prepress 7 Beside the prepress chamber 3 there is a prepress 7, comprising a prepress unit 8 being quadrantal in cross-section and having a fore- ward wall 19, which at its lower perpendicular side is pivotably journalled on an axis 9 and is driven by a cylinder unit 10.
  • the complete prepress unit 8 is arranged on a carriage 11, which is horizontally reciprocable along a guiding or rails 12 between a retracted position shown in Fig. 1 and an extended position shown in Fig. 2 by means of a cylinder unit 13.
  • the volume of the prepress chamber 3 is decreased and a precompression takes place in a first step.
  • an upper plate 14 follows the movement of the carriage and prevents goods to fall down behind the carriage 11.
  • a second compression takes place in a second step, by pivoting the prepress unit 8 around the axis 9 to the position shown in broken lines in Fig. 2, thereby precompressing the material in the prepress chamber 3 down into the main press chamber 4 by the forward wall 19. During this pivoting movement, the plate 14 prevents the goods to fall down behind the back rim of the prepress unit 8.
  • the prepress unit 8 is repivoted and the carriage is retracted to the position shown in Fig. 1, and a continued filling of goods takes place, followed by a precompression as stated above.
  • a main compression takes place by means of the plunger 16, which is driven by a cylinder unit 17 and the bale is pressed into a channel 18, of which only the entry is shown on the drawings.
  • the continued baling operation is in accordance with known technique and is thus not given in detail here.
  • the method described above is used when the compression of bulky goods takes place.
  • heavy goods are compressed, such as periodicals, this is done with the carriage in the position shown in Fig. 2 and the plates 5 are unfolded.
  • a material distributor 6 is unfolded and activated, which rotates and distributes and partially disintegrates the goods.
  • a precompression is made by pivoting the prepress unit 8 forwards and downwards, one or several times and finally a main compression is made.
  • the inlet opening can now be made about double as wide as previously which entails an increased capacity.
  • a continuous goods infeed takes place, but it is also possible to stop the infeed during the compression operation.
  • the increased efficiency can also be used for making the machine considerably smaller.
