Definitions

  • This invention relates to an improved press for the compaction of materials, such as wool, into bales.
  • the press to be described in more detail below has been designed principally for the compaction of wool into bales, the invention is equally applicable to the compaction of other materials, such as waste fabrics, paper, particularly shredded paper, fibrous materials generally and any other material that can be compacted under pressure.
  • the press may be capable of compacting salt into blocks suitable for stock licks.
  • rollers were the most effective means of feeding the wool to bale forming space, provided there was relative reciprocating movement between the feeding means and the bale-forming space to ensure uniform distribution of the wool within the space.
  • the success of this arrangement was totally unexpected and was if anything dissuaded by the previous work involving the use of rollers as the feeding mechanism.
  • the invention provides a press for compacting materials such as wool into bales, comprising a receptacle defining a bale-forming space, means defining a front wall of said bale-forming space, roller means defining part of said front wall of said bale-forming space for feeding material directly into said bale-forming space for compaction, means for applying pressure to the material in said bale-forming space, means for applying bands or the like to the compressed material to hold said material in the form of a bale, and means for causing relative reciprocation of said receptacle and said front wall and roller means transversely of the direction of feeding of said material into said bale-forming space in timed relation to the rate of feeding whereby said material is evenly distributed and compacted within the bale-forming space.
  • a pair of rollers extend across the full width of the receptacle and scraper blades preferably extend into contact with or in close proximity to the rollers to effectively close the open face of the receptacle against the escape of material fed into the bale-forming space.
  • the scraper blades also prevent the wool fibres wrapping around the rollers.
  • the receptacle is reciprocated up and down a structure which defines the front wall of the receptacle between positions in which the top and bottom walls of the receptacle are respectively aligned with the nip between the rollers.
  • the material to be baled is evenly distributed across the entire cross section of the bale-forming space.
  • the receptacle is also able to move above the top roller to enable banding of the bale to take place in a manner similar to that described in the earlier application referred to above and as described in greater detail below.
  • the front wall of the receptacle has an arcuate form and the receptacle is pivoted for arcuate reciprocating movement relative to said front wall.
  • This preferred arrangement increases the speed at which the receptacle may be reciprocated relative to the front wall and feed rollers and facilitates smoother and quieter operation of the press.
  • the arcuate front wall of the receptacle is defined by a series of rollers positioned above and below the feeding rollers.
  • smoother operation is to be expected due to the reduction in friction between the wall in bale-forming space and the rollers defining the front wall.
  • the bale must be banded sideways and the side walls defining the receptacle are slotted for this purpose.
  • the means for applying pressure to the material in the bale-forming space preferably comprises a moveable top wall of the receptacle together with means for applying a force to the top wall.
  • the pressure applying means operates in a manner similar to the pressure plate in a hay baler.
  • the improved press embodying the present invention feeds the material to be compressed directly into the bale-forming space without any need for passage through a mouth which is considerably narrower than the bale width in the same direction. This results in part from the use of rollers as the material feeding means and in part from the reciprocating movement of the receptacle across the rollers as they feed the material to be pressed.
  • the material being fed by the rollers is drawn in that direction between the material already in the bale-forming space and one of the rollers and compression of the material occurs between that roller and the front wall of the bale-forming space and the material already in the bale-forming space rather than solely as the result of the pressure applied to the wool by the feeding means as in the earlier application referred to above.
  • the improved press embodying the invention comprises a base frame 1 supporting a pair of upstanding angle section posts 2, one of the flanges of which rotatably supports the journals of a pair of driven rollers 3, 4.
  • the top roller 4 is moveable in a vertical plane within slot 5 and is biased towards roller 3 by means of a compression spring 6 which applies a force of between .5 and 1 tonne to the roller 4.
  • a face plate 7 extends between the two posts 2 and closes the space between them except for the opening within which the rollers 3 and 4 are positioned.
  • a pair of roller wipers 8 are fixed to the face plate 7 in the manner shown in Fig.
  • the uppermost portion of the face plate 7 is formed within slots 9, as shown in Figs. 3 to 6 of the drawings, to facilitate banding of the bale as described in more detail below.
  • a receptacle 10 is mounted for reciprocating movement up and down the posts 2.
  • the receptacle 10 includes side walls 11, a bottom wall 12 and a moveable top wall 13 which between them define a bale-forming space 14.
  • Each side wall 11 has a pair of rollers 15 secured thereto and the rollers engage one of the flanges of the posts to facilitate the reciprocating movement of the receptacle 10.
  • the receptacle 10 is reciprocated by means of a cable 16, the ends of which are attached to one of the side walls 11 as shown in Figure 1 and which passes over upper and lower sheaves 17 and 18, the upper sheaf 17 being driven in timed relation to the rollers 3 and 4 so that the reciprocating movement of the receptacle 10 is at about the same speed as the rate of feed of wool by means of the rollers 3 and 4.
  • the receptacle 10 may be reciprocated up and down tracks by means of rack and pinion gearing.
  • the top wall 13 of the receptacle 10 is acted on by a pair of compression springs 19 which are held in place by a cross channel 20 which is adjustably bolted to the upper edge of each side wall 11.
  • the springs 19 apply a force of about 10 tonnes to the bale B being formed in the bale-forming space 14 in a manner similar to the pressure plate in a hay baler.
  • Wool W to be baled is fed to the nip between the rollers 3 and 4 by means of a conveyor belt 21 arranged generally as shown in Fig. 1 of the drawings.
  • the conveyor 21 is of course driven in timed relation to the rollers 3 and 4 to ensure that a uniform amount of wool W is presented to the rollers 3 and 4.
  • bale banding material 23 Several reels 22 of bale banding material 23 are supported under the receptacle 10 and are fed between driven pinch rollers 24 into the bale-forming space 14.
  • a bale B within the bale-forming space 14 will now be described.
  • the pressure plate 13 applies pressure to both the existing bale B and the bale B' which is in the process of being formed.
  • the pressure plate 13 extends angularly downwardly towards the bottom wall 12 to define a wedge shaped space.
  • the pressure plate 13 is raised until the required vertical bale dimension is achieved whereupon the force applied by means of the springs 19 prevents further growth of the bale B.
  • FIG. 7 of the drawings shows the receptacle 10 in its elevated position with a bale B having just been completed and banded.
  • the tail end of the bands 23 extend across the face of the bale-forming space whereupon the receptacle 10 is lowered to the position shown in Figure 8 and the rollers 3 and 4 are again driven to feed wool W into the bale-forming space 14.
  • the bands 23 are drawn into the bale-forming space in the manner shown in Figures 3 to 6 of the drawings until a further bale B' is completed.
  • the receptacle 10 is again moved to its elevated position in which the bottom wall 12 is above the level of the slots 9 in the face plate 7, whereupon the bands 23 are forced through the slots into a loop L which moves up the face of the bale-forming space and across the top wall 13, which is slotted for this purpose until the condition shown'in Figure 10 is reached.
  • the bands 23 are cut at the end of the loop and the ends of the bands are crimped together in the usual manner to completely surround the newly formed bale B'.
  • the receptacle 10 is then lowered to the position shown in Figure 3 of the drawings whereupon formation of a further new bale is commenced.
  • bale-forming process is interrupted only for the time required to achieve banding of a completed bale. Otherwise, the bale-forming procedure is continuous. It will also be appreciated that uniform distribution and compression of the wool within the bale is achieved and it has been found that the densities required to achieve prescribed bale weights within the prescribed jumbo bale dimensions are easily achieved.
  • a press which is suitable for use in a shearing shed is shown somewhat schematically. It will of course be appreciated that the same features may be incorporated in a press of considerably larger dimensions suitable for pressing operations on a larger scale.
  • the press shown comprises a generally rectangular base frame 100, which may be provided with wheels (not shown), supporting a pair of opposed uprights 101 at the rear end of the frame, and a pair of opposed upstanding side members 102 at the front of the frame and connected by cross members 103, 104.
  • the uprights 101 support bearings,105 for pivot shafts 106 extending between the side frames 107 of a receptacle 108 and the bearings 105.
  • the receptacle 108 includes a fixed bottom wall 109, a pair of opposed side walls 110, and move able top wall 111 to which a suitable force is applied mechanically or hydraulically (shown schematically as hydraulic ram R) as in the previous embodiment, and together defining a bale-forming space 112.
  • the side walls 110 are formed by spaced slats 113 leaving openings 114 for the bands b used to contain the bale B formed in the space 112.
  • a pair of driven feed rollers 115, 116 are arranged between the side members 102 and midway between the ends of the side members 102 ahead of a feed conveyor 117 for feeding wool thereto.
  • a multiplicity of idler rollers 118 extend between the side members 102 above the roller 115 and a similar multiplicity of rollers 119 extend between the side members 102 below the roller 116.
  • the rollers 118 and 119 are arranged in a generally arcuate line corresponding to the path followed by the mouth of the bale receptacle 108 as it is arcuately reciprocated by an arm 120 connected to a driven crank wheel or the like (not shown).
  • Each of the rollers 118 and 119 extends across the width of the mouth of the bale-forming receptacle 108 and is arranged sufficiently close to the adjacent rollers of the multiplicity to prevent es.cape of wool from the bale-forming space 112.
  • the rollers 115, 116 are spaced slightly in front of the rollers 118 and 119 to reduce the effect of the opposite movement of the receptacle 108 relative to the direction of rotation of each of the rollers 115 and 116.
  • a supply of wool is available behind the rollers to enable movement of the receptacle without creating a large amount of drag between the roller moving in a direction opposite to the direction of movement of the receptacle 108 at that time.
  • rollers 115 and 116 contribute to the compression of..the wool in the bale-forming space 112
  • the rollers 118 and 119 do a large amount of the work in this respect.
  • the use of the rollers 118, 119 reduces the friction between the wool in the bale-forming space 112 and the front wall of the receptacle defined by the rollers 118, l19 during reciprocation of the receptacle 108, and this in turn facilitates smooth operation of the press and reduces the noise associated with this operation.
  • the receptacle 200 is once again pivoted at the rear thereof and arcuately reciprocated relative to an arcuate face plate 201.
  • the feed rollers 202, 203 are arranged similarly to those in the first embodiment described above and the pressing operation is basically the same as the first embodiment except that the receptacle 200 is arcuately reciprocated by a crank wheel 204 and arm 205.
  • the top wall 206 of the receptacle 200 is in this embodiment formed in two parts 207, 208, each part being pivoted at its forward end and having a mechanical or hydraulic forcesupplying means F acting thereon.
  • the formation of the top wall 206 in two parts reduces the strength requirements of each part and also allows the banding operation to be performed more rearwardly of the receptacle 200 where the movement of the receptacle is not so great.
  • the wall parts 207, 208 and the face plate 201 are slotted in a similar manner to the first embodiment described above.
  • the first embodiment is particularly simple in construction and therefore has the advantage of being particularly easy and cheap to construct.
  • a bag may be positioned in the bale-forming space and the front wall or face plate extended beyond the side members to enable the bag to be partly closed before formation of the next bale.
  • the face plate 201 may be extended at the top and means provided to enable further pivotal movement of the receptacle 200 to a position where two of the flaps of the bag may be connected over the extended face plate whereupon the receptacle 200 is further pivoted to expose the top of the bale to enable securement of all of the flaps.
  • the bale may then be ejected from the receptacle, say by means of a ram, or a further bag positioned on top of the completed bale and the receptacle positioned for feeding of further wool into the bale-forming space to form a further bale in the bag positioned in the bale-forming space whereby the existing bale is gradually displaced from the press.
