Abstract
Description
- The present invention relates to a hydraulic 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. When this chamber is filled, 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. At this stage, 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 maincompressing takes place until a predetermined bale length has been achieved, whereupon baling takes place. The bales are successively fed out from the channel.
- Bale presses without any prepress do also exist.
- At some applications it is desirable to have a wider inlet opening in order to be able to accomodate larger emty boxes and similar. If the above-mentioned bale press was constructed having a wider inlet opening, at least the prepress had to be proportionally enlarged and the total bale press should be too bulky for many applications. The other way around, 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 above-mentioned type where it is possible to use a wider inlet opening or alternatively the machine size can be diminished.
- Thus, according to the invention, the precompressing takes place in two steps, a first precompressing in the horizontal direction and a subsequent precompressing down into the main press chamber. After the first precompressing, further material can be loaded before the second precompressing takes place down into the main chamber.
- Thus, the present invention provides a bale press for compressing bulky goods and compressing the goods into bales. The bale press comprises an inlet section, a prepress chamber and a main press chamber. A main press plunger is adapted to compress the goods into a bale. The prepress chamber comprises a prepress having a prepress unit mounted on a carriage and pivotable around an axis positioned on the carriage. The carriage is reciprocable between a retracted position leaving the prepress chamber essentially free and an extended position substantially decreasing the volume of the prepress chamber.
- The prepress unit has the shape of a fourth of a cylinder having a forward, essentially vertical wall, which performs the first precompressing during the movement of the carriage to the extended position. Thereafter the prepress unit is pivoted around its axis so that the forward wall sweeps over an arc downwards to a lower, essentially horizontal position, thus in order to precompress the goods from the prepress chamber into the main press chamber in a second step.
- The movements of the carriage is preferably horizontal and all movements are imparted by means of hydraulic cylinder devices.
- The invention also provides a method for compression of bulky goods into bales. In accordance with the method, the precompression takes place in two distinctly separate steps, viz a first step including the horizontal movement of the carriage and a second step including the pivoting of the prepress unit.
- Further objects and features of the invention will appear at the detailed description below of a preferred embodiment of the invention by reference to the drawings. Fig. 1 is a longitudinal side view with the side plate removed of the bale press in the start position or load position, while Fig. 2 is a similar side view of the bale. press of Fig. 1 after the horizontal compress operation.
- The bale press according to the invention is shown in a longitudinal side view in Fig. 1 with the side plate removes. The bale press comprises an
inlet section 2, aprepress chamber 3 and amain press chamber 4. Theinlet section 2 is intended to be loaded from above. - Beside the
prepress chamber 3 there is a prepress 7, comprising aprepress unit 8 in the shape of a fourth of a cylinder having aforward wall 19, which at its lower perpendicular side is pivotably journalled on an axis 9 and is driven by acylinder unit 10. Thecomplete prepress unit 8 is arranged on acarriage 11, which is horizontally reciprocable along a guiding orrails 12 between a retracted position shown in Fig. 1 and an extended position shown in Fig. 2 by means of acylinder unit 13. During the horizontal movement, the volume of theprepress chamber 3 is decreased and a precompression or comprimation takes place in a first step. Simultaneously with this horizontal movement of the carriage, anupper plate 14 follows the movement of the carriage and prevents goods to fall down behind thecarriage 11. - After the first compression, 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 comprimating or precompressing the material in theprepress chamber 3 down into themain press chamber 4 by theforward wall 19. During this pivoting movement, theplate 14 prevents the goods to fall down behind the back rim of theprepress unit 8. - Thereafter, 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. When themain press chamber 4 is full, a main compression takes place by means of theplunger 16, which is driven by acylinder unit 17 and the bale is pressed into achannel 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. - Experiments have proven that the addition of said horizontal precompression step at certain troublesome materials gives a firm and stable completed bale, where previously problems have been encountered since the bale was too softly crammed. This is specially true for big cardboard boxes having relatively loose walls.
- The method described above is used when the compression of bulky goods takes place. When heavy goods is compressed, such as periodicals, this is done with the carriage in the position shown in Fig. 2 and the
plates 5 are unfolded. Moreover, a material distributor 6 is unfolded and activated, which rotates and distributes and partially disintegrates the goods. Thereafter, 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. During the precompression normally a continuous goods infed takes place, but it is also possible to stop the infed during the compression operation.
- The increased efficiency can also be used for making the machine considerably smaller.
- In the above a preferred embodiment of the invention has been described in order to elucidate the invention. However, the invention is not limited to the embodiment shown but can be modified in many respects within the scope of the invention, as defined in the appended claims.
