Definitions

  • This invention relates to a method and an apparatus for manufacturing bales of voluminous fibre material, partic ⁇ ularly textile material.
  • bales are manufactured in a bale press by compressing and pressing the fibre material, normally in several steps. Thereafter each bale is packed and wrapped, which can take place in or outside the press.
  • the Swedish patent application 7705269-. discloses a bale press of this kind.
  • the pressing is carried out in several steps, and the final pressing of the bale takes place in a pressing chamber.
  • the final pressing pressure thereafter is partially relieved so that the bale is permitted to expand. It is thereby possible to move the bale out of the pressing chamber to the packing and wrapping apparatus while maintaining said lower pressure, without giving rise to detrimental friction forces.
  • the present invention offers a solution of the aforesaid problems, in that a special pressing box is used both for transporting the bale from a press to the packing and wrapping apparatus and for serving as final .pressing chamber.
  • a special pressing box is used both for transporting the bale from a press to the packing and wrapping apparatus and for serving as final .pressing chamber.
  • Pig. 1 shows three low-pressure presses 1 for pre-compress- ing and pre-pressing the fibre material. These presses have low capacity and are intended to produce bales of relatively low density. The number of such presses can vary, depend ⁇ ing on production and capacity.
  • a pressing box 3 On a first conveyor 2 a pressing box 3 is located. Each box 3 can be moved on the conveyor to a conveyor carriage 4, which is movable along a first track 5. Said first conveyor carriage 4 is capable to co-operate with an intermediate conveyor 6 provided to move the box 3 to a second conveyor carriage 7, which is movable along a second track 8. Adjacent said second track 8 a final press 9 is located. A pusher 10 is provided directly in front of the final press 9 and can be moved along a track 11. After the final press 9 a packing and wrapping apparatus 12 is located. An outlet conveyor 13 moves the completed bale for its further handling.
  • Each of the low-pressure presses 1 shown in Pig. 2 is prov ⁇ ided with a shaft 14, into which the fibre material can "snow" down.
  • a uniform distribution of the material across the cross-section of the shaft is obtained, so that a symmetric bale can be produced.
  • the material is collected on a damper 16 in a scales cont ⁇ ainer 15, which is supported on a scales mechanism 15A.
  • an upper damper 17 is inserted which blocks the fibre material flow to the scales container 15.
  • the damper l ⁇ is folded down, and the supported material drops down and fills the lower portion of the shaft.
  • new supplied material is supported by the upper damper 17.
  • a compressing plate 18 is folded up, and at the same time the damper 16 is closed.
  • the material is now compressed in that the plate 18 is moved downward to the upper edge of a discharge opening 19 in the side surface of the shaft.
  • the opening 19 connects the shaft 14 to a pre-pressing chamber 20, in which a pre-pressing ram 21 is located.
  • a vertical plate 22 maintains the opening 19 closed during ongoing compressing and pressing.
  • the pre-compressed layers are introduced into the pre-press ⁇ ing chamber 20 by means of a hydraulically operated lateral- -movement plate. ' 23. Prior to this introduction the pre- -pressing ram 21 has been moved down by a hydraulic motor 24. The material, which already has been pre-pressed in the chamber 20, is prevented from falling down by means of forks 25, which can be moved into and out of the chamber 20.
  • the aforesaid pressing operations are repeated until the desired number of pre-compressed layers have been collected in the pre-pressing chamber 20, for example 4-5 layers, depending on fibre density, bale dimensions etc.
  • the number can be varied.
  • the pressing force for example, can be about 0.75 MN (meganewton) which is relieved to about 0,10 MN.
  • the pressing box 3 consists of a frame 26 with two opposed sidewalls 27, a stationary upper plate 28 and vertically movable lower plate 29. Said lower plate 29 is guided by guide members 30.
  • the end wall portions of the pressing box are open. At the end wall portions guide pins 31 are provided to co-operate with corresponding recesses at the discharge opening 32 of the pre-pressing chamber 20.
  • the pressing box thus, can be coupled together with the pre-pressing chamber 20, and retaining is effected by means of holding members 33 co-operating with recesses 34 in the pressing box.
  • a hydraulic pusher 35 By means of a hydraulic pusher 35 the bale pre-pressed according to above can be moved from the pre-pressing chamber 20 into the box 3.
  • the height of the box corresponds to the space in the pre-pressing chamber 20, the bale can be transferred while maintaining the pressing force.
  • the distance between the opposed sidewalls In order to facilitate the transfer and to prevent damages on the fibres due to;'fraction against the sidewa-_lls, the distance between the opposed sidewalls
  • the box is transported in between the pressing plates 36,37 of the final press by means of the conveyor carriage 7, on which a conveying belt 38 is provided. Furthermore, a conveyor (not shown) is provided in the final press 9 for facilitating the transport of the pressing box 3 into and out of the final press.
  • the upper pressing plate 36 is movable by means of a hydraulic motor 39•
  • the upper and, respectively, lower plate 28,29 of the box 3 is coupled together with the respective pressing plate 36,37.
  • the pressing box 3 constitutes the pressing chamber, and the lower plate 29 of the box 3 is moved along the guide members 30 toward the upper plate 28, thereby pressing the bale together.
  • the final pressing is carried out in two steps.
  • the movable pressing plate 36 of the press 9 first assumes a pressing position where the bale is compressed to a height lower than the final bale height, and thereafter an expansion position corresponding to the final bale height. After a desired adjustable holding time in the pressing position, the movable pressing plate 36 returns to the expansion position.
  • the final pressing force for example, can amount to 4 MN.
  • the completely pressed bale is pushed out of the box 3 by means of the pusher 10.
  • the packing and wrapping apparatus 12 preferably is located immediately adjacent the final press so that the packing material 40 forms a curtain between them.
  • the apparatus 12 is equipped with an upper and a lower conveying path 41,42, which maintain the height of the bale and therewith the pressing force during the packing.
  • the packing material 40 is folded about the bale when it is being pushed out and thereby envelops the leading short side, upper and lower side of the bale.
  • Special members (not shown) fold the packing material inward against the bale. No direct contact occurs between fibres and roll conveyor, and thereby mixing of fibres in this phase is prevented.
  • the wrapping unit is of conventional type and located so that the bale is compressed locally in the place where the tie wire is attached. Thereby the expansion of the bale after the wrapping is reduced.
  • the wrapping is carried out with several wires while the bale is advanced. Transport paths are provided even after the wrapping unit, so that the bale portion already wrapped is retained under load until all wrapping wires have been attached on the bale.
  • the complete bale thereafter is handled by the discharge conveyor 13.
  • the present invention renders it possible to serve several low-pressure presses with one final press of high capacity. This can be effected without risk of mixing different fibres from the low-pressure presses, by using a special pressing box.
  • the baling at older pressing lines with low capacity furthermore, can be made more efficient and automated without too extensive reconstruction.

Abstract

Le matériau fibreux subit une compression et un pressage préalables dans des presses à faible pression (1). Les balles préalablement pressées sont transférées, au moyen de boîtes de pressage (3) transportables, sur une presse finale (9) où elles subissent un pressage définitif tandis qu'elles sont dans les boîtes de pressage (3). La boîte de pressage (3) est donc pourvue d'un plateau supérieur et d'un plateau inférieur (28, 29) qui sont mobiles l'un vers l'autre et l'un à partir de l'autre. La balle définitivement pressée est éjectée de la boîte de pressage (3) directement dans un appareil de conditionnement et d'enveloppage (12).
