Abstract
Description
- The present invention relates to metal baling machines and more particularly to metal baling machines incorporating a metal shear.
- A known metal baler includes a hydraulically controlled hinged lid which is used to press metal down into a baling box wherein a hydraulic ram is operative to compress the metal into a bale. The upper edges of the sides of the box and the edges of the lid form co-operating cutting edges thereby allowing oversize material to be placed on the top of the box the material being cut off when the lid is hydraulically lowered. The portion "within" the box is thereby ready to be compressed and by separated operations large metal sheets or long lengths can be cut up and forced down into the box.
- A disadvantage with the known baler is that the above procedure can be dangerous since the portion of large sheet or long length not within the box may fly off when the rest is cut. With the enormous shearing forces used, often in excess of 100 tons, this can be very dangerous. With thin sheets such as for example the body panels of large lorries the sheet may not cut cleanly but only partially cut through. The operator therefore has to repeat the operation thus wasting time due to the inefficient operation of the machine.
- It is an object of the present invention to provide an improved metal baler which is safer and more efficient in operation.
- According to the present invention there is provided a metal baler including a box, a hinged lid for the box the hinged lid having means for crushing in a downward direction material placed in or on top of the box, the box having at least one movable side which has means for crushing the material within the box when the lid is in a closed position and including clamp means attached to the box for clamping material to be crushed by the hinged lid.
- Preferably the clamp means includes a clamping table rigidly attached to the box and a clamping arm rotatably mounted on the baler to co-operate with the clamping table to clamp material overlapping the top of the box.
- Preferably the clamping arm is hydraulically controlled. The arm may be controlled in sequence with the hinged lid.
- The arm is preferably mounted on the same hinge axis as the hinged lid the hinge axle being extended on one side of the box to accommodate the clamping arm.
- The arm is preferably provided with a serrated surface on the side co-operating with the clamping table.
- Embodiments of the present invention will now be described, by way of example with reference to the accompanying drawings, in which:-
- Figure 1 shows a metal baler having means for cutting oversize material;
- Figure 2 shows diagrammatically in side elevation the baler of Figure 1 with clamping means according to the present inventionlr2
- Figure 3 shows diagrammatically a portion of the front of the baler of Figure 2 in front elevation illustrating the clamp table according to the present invention; and
- Figure 4 shows diagrammatically a front elevation of a portion of the baler of Figure 2 illustrating the clamp arm.
- With reference now to Figure 1 the
baler 10 comprises abox 12 with a rotatably mountedlid 14. Thelid 14 is mounted on a massive hinge pin oraxle 16 and is moved by ahydraulic ram 18 controlled by controls 20. Compressors 22, 24 provide the power for the hydraulic rams, the second ram (not shown) being operable in known manner when thelid 14 is closed onbox 12 to push the end ofbox 12 opposite to theend 26 towards theend 26 to form the bale. Theend 26 forms a door which may be lifted byrams guard 32 is provided to protect the operator from being injured when thelid 14 is descending.Wheels 33 etc. are provided to allow the baler to be moved to a desired location. - The
lid 14 is, in the present invention, provided withcutting edges co-operating cutting edges box 12. Edge 50 is "V" shaped to provide commencement atpoint 52 of the cutting of any large sheet which overlaps this front edge.Edges upstanding serrations - It is possible therefore, to place very large sheet of material such as aluminium or steel plate across the top of
box 12 and to "nibble" away at them by repeated operations oflid 14. A number of problems arise however when handling large sheets or long tubes etc. Firstly, if the sheet is very large, it tends to fall off the baler thereby not being cut or only partially cut. Thus, a second operator is required to hold the sheet and this can be dangerous because the sheet may suddenly jerk when being cut thereby possibly injuring the operator. For large thin sheets, especially with a baler which is getting worn thecutting edges box 12. The operator may have difficulty in re-arranging the sheet for the next cut and may be cut by any jagged edges. - Thus, though the baler of Figure 1 is improved over known balers, having the ability to cut a sheet on three edges, this leads to the above problems and the improvement to the machine as shown in Figures 2, 3 and 4 seeks to overcome these problems.
- With reference now to Figures 2, 3 and 4 the improvement comprises a clamping system for clamping the material to be baled. The clamping system includes a
clamping arm 60 and a clamping table 62. Theclamping arm 60 is preferably operated by ahydraulic ram 64 and is pivoted about themain hinge axle 16 to be able to press down onto the top surface of table 62. Thepivot point 65 for thehydraulic ram 64 andarm 60 is arranged to provide adequate leverage such that thearm 60 exerts a desired pressure onto the table 62. The advantage of using thesame hinge axles 16 as thelid 14 is that theaxle 16 is .0 very strong since it has to provide the support for thelid 14 and therefore it can readily provide the support for thearm 60. - The
arm 60 may be operated by a lever and ratchet system to allow quick hand operation but this is not preferred. Since most balers have hydraulic rams to perform the baling operations, it is preferred to use hydraulics for theclamping arm 60. - With reference to Figure 3 the clamp table 62 is made fairly wide relative to the width of the clamp arm and thereby gives additional support for the material to be cut. The
table top 62 is supported by a number ofbracket plates 66 which are preferably welded to the table and to the body of thebox 14 as indicated at 68 and 70. Theplates 66 are of thick plate thereforetable top 60 is capable of withstanding large pressure from theclamp arm 60. Aclearance gap 67 is preferably provided between the top of table 62 and the side ofbox 14. - With reference now to Figure 4 the hydraulic cylinder acts on
pivot 65 which is a short axle mounted between afirst plate 72 and theleverage portion 74 ofclamp arm 60. This provides a balanced turning moment for thearm 60. - The
arm 60 may be provided withteeth 61 to produce a greater gripping action for material laid on table 62. These teeth are preferably shaped as shown to provide, whenclamp arm 60 is lowered, a series ofvertical stops 80 which prevents material such as round tubes from rolling away from thelid 14. Theupstanding serrations - The
clamping arm 60 may be sequentially controlled such that it descends just prior tolid 14, the control lever forlid 14 serving to firstly operatehydraulic ram 64. This enables the operator to clamp and cut by a single operation. Alternativelyhydraulic ram 64 may be separately controlled which may be beneficial for positioning of the material to be cut prior tolid 14 being operated. This may lead to more efficient operation of the baler by the operative. Also as referred to above for a simple clamphydraulic ram 64 may be replaced by a mechanical lever and ratchet or peg arrangement (not shown) to provide a relatively simple clamp which may be adquate for small balers. - Whichever clamping arrangement is used, the
clamp arm 60 will hold the material to be cut allowing the operator to retire behindguard 32 before operating themain ram 18. Thus, any pieces of metal which fly off will not injure the operator. Thus, an efficient cutting and baling operation may be carried out in safety. - In a practical embodiment the baling box was constructed from 2.5 inch and 4 inch thick metal steel plate with the shearing blades on the box and lid being replaceable and being made of hardened steel. The clamp arm was also of 2.5 inch mild steel and the table top and bracket plates being of 1 inch metal steel plate.
