Press and method for forming bales of textile, in particular clothing

The invention relates to a press for forming bales of textile, in particular clothing, comprising at least one pressing plate and means for wrapping compressed textile with foil, cord or the like. The invention further relates to a method for forming bales of textile.

The international patent application WO 2005/012098 describes a press for textile and other materials, which comprises a first pre-pressing station (indicated in the Figures by number 103) and a second pressing and binding station (105). During transfer of a bale of textile pre-pressed in the horizontal direction from the first to the second station, the bale intercepts a film such that three (T2, T3 and T4) of the six sides of the bale are surrounded by the film. In the second station the bale is pressed in the vertical direction and the remaining three sides (T5, T6 and T7) are wrapped with foil.

The invention has for its object to provide an improved press, in particular a relatively compact press and / or a press with which a bale can be obtained with a single press stroke.

For this purpose, the press according to the invention is characterized by a mold which is open on two opposite sides and which, during pressing, surrounds the pressing plate. The press is preferably provided with means for reciprocating the mold back and forth in the pressing direction, ie in the case of a vertical press, between at least a first position (Figure 2) for filling the mold with textile and a second position (Figure 30 3) for unloading a bale of compressed textile.

Textiles can thus be pressed, wrapped and released in a single reciprocating movement of both the pressing plate and the mold. Moreover, the mold can be used to measure the amount of textile per bale.

The press is further simplified if the means for wrapping compressed textile are attached or connected to the mold at or near the open end remote from the press plate, i.e. usually the lower edge of the mold.

The bales obtained with the present press can, for example, be transported with containers. In this connection it is preferable that the inside dimensions (height x 10 width x depth) of the mold are in a range of 1.5 to 2.5 meters (height), 1.0 to 1.3 meters (width) and 1.0 to 1.3 meters (depth) . The bales obtained with the press can then be loaded two wide, two high and for instance ten (or eleven) deep in a standard (or "high cube") container in order to achieve an at least substantially maximum loading of that container.

The invention furthermore relates to a method for forming bales of textile, in particular clothing, wherein textile is introduced into a mold, which mold is open on two opposite sides, the textile being compressed in the mold, preferably by means of a pressing plate, the mold and the compressed textile are moved relative to each other in the pressing direction, so that the textile is (gradually) released, the discharged textile is moved around, ie around the pressing direction, with foil, cord or the like. wrapped, preferably while the pressing plate rests on the textile. Furthermore, the volume of the textile is preferably reduced by at least 20% or at least 30%.

The invention will now be elucidated with reference to the figures, in which a preferred embodiment of a press according to the present invention is schematically shown.

Figure 1 is a front view of a press according to the invention provided with a vertically movable mold.

Figure 2 is a rear perspective view of the press of Figure 1 with the mold in the lower position.

Figure 3 is a rear perspective view of the press of Figure 1 with the mold in the upper position.

The Figures show a press 1 for forming bales of textile, in particular collected clothing, comprising a frame 2 and a mold 3, which, by means of one or more cylinders, in this example four hydraulic cylinders 4, in the frame 2 is attached and can be moved vertically up and down between a lower position, in which the mold 3 can be filled with clothing (Figure 2), and an upper position, in which a finished bale can be removed from the press (Figure 3), as will be explained in more detail below.

The mold 3 comprises four substantially closed, vertical walls 5, for example manufactured from plates of stainless steel, and is open at the top and bottom. In this example, the mold 3 is provided near the underside with roller pairs 6, one at each corner of the mold 3, in which a circular rail 7 is rotatably suspended. An assembly of an electric motor 8 and a wheel 9 coupled thereto is hinged to at least one of the walls 5 of the mold 3. The wheel 9 is pressed against the inside of the rail 7 by means of a spring (not shown). Furthermore, a holder 10 for a roll of film 11 is attached to the rail 7, for example a shrink film with a width between 40 and 50 cm.

Above the mold 3 is a square pressing plate 12, which is attached to the top of the frame 2 by means of one or more cylinders, in this example four hydraulic cylinders 13, which can be moved up and down vertically and which can be moved in the mold 3 fits. The imaginary axis of rotation of rail 7 and the holder 10 and the direction in which the mold 3 and the plate 12 can be moved up and down (the pressing direction) coincide, at least run substantially parallel.

Below the mold 3 there is a conveyor track 14, for example a roller or chain conveyor, with which pallets 15 can be supplied and taken away. During the compression of the clothing, a pallet 15 acts as a lower pressing plate.

Approximately halfway the frame 2 there is a supply, in particular a conveyor track 16, one end of which is outside the circumference of the mold 3 and above the upper edge, if the mold 3 takes the lower position (as shown in Figure 2). ). The press 1 can optionally be provided with means for weighing the clothing 15 which is located in the mold.

During operation, a pallet 15 is placed with the conveyor track 14 underneath the mold 3 and the mold 3 is lowered over or to just above this pallet 15. For example, instead of or in addition to the pallet, a cardboard box which (exactly) can fits into the mold.

Textiles, for example clothing, are then supplied loose and / or packaged in bags, with the supply conveyor track 16 and poured into the mold 3. When the mold 3 is filled or a preset weight has been reached, the pressing plate 12 is moved downwards and the clothing is pressed between the pressing plate 12 and the pallet 15 into a bale, whereby the volume of the textile is reduced by more than 30% .

After the pressing stroke is completed, one end of the foil 11 is attached to the textile or the pallet 15, for example by means of a clamp, and the mold 3 is gradually pulled upwards by means of the hydraulic cylinders 4, while the pressing plate 12 hold the bale down to 35. At the same time, the rail 7 and the holder 10 are rotated about an imaginary axis, which, as mentioned, coincides with or runs parallel to the pressing direction, so that the released part of the pressed bale directly and all around (over all four sides) with foil is wrapped.

It is thereby preferred that the effective pitch of the windings is smaller than the width of the film, so that the windings overlap each other. After the final winding, the foil is cut loose from the roll with a heated wire and attached to the bale. Optionally, a seal, such as a cardboard plate, can be applied to the top of the textile before or after pressing.

The finished bale is removed with the conveyor track 14 and a subsequent pallet 15 is subsequently placed under the mold 3, after which the above cycle is repeated.

Large quantities of clothing can thus be baled in a relatively short time.

The invention is not limited to the embodiments described above and can be varied in numerous ways within the scope of the claims. It is thus possible to design the mold in such a way that it can easily be taken out of the mold and replaced by another mold. It thus becomes possible to fill the molds elsewhere, for instance at one or more collection points, and thus filled molds, provided on the underside with a loose, at least releasable, bottom, for example a pallet, in the press.
