Definitions

  • the present invention concerns baling presses of the type used to crush and compress loose waste materials such as discarded wrappers for example, so as to form coherent blocks of densified material which may be handled as unitized loads by conventional handling equipment such as stillage trucks, or hoists for example.
  • the present specification describes an improved means for ejecting blocks of densified waste material from the compaction chambers of otherwise-conventional baling presses and optionally includes a means for producing blocks of waste material which are more easily handled by mechanical means than those produced hitherto.
  • waste material is typically allowed to slide or fall into an open-topped box-like compaction chamber, and periodically a hydraulically-powered plunger which is mounted above the chamber is caused to move downwardly until it enters the chamber where it crushes and compresses the waste material against the flat bottom face (or floor) of the chamber.
  • the plunger is then caused to withdraw to its idle position above the compaction chamber, exposing the partially-filled chamber for the addition of further loose waste materials.
  • the shape and dimensions of the plunger in a baling press are similar to those of the compaction chamber, the plunger typically being a sliding fit inside the chamber.
  • the above process is repeated until the chamber is filled with densified waste material when, with the plunger pressing downwardly so as to prevent the materials in the chamber from springing-back or partially recovering their shape, one or more bands or straps are tied around the bundle (through slits or grooves in the sides and floor of the chamber, and sometimes also in the face of the plunger).
  • the plunger is then withdrawn to its idle position and one side of the baling chamber is removed (usually it is hinged like a door) so as to expose the densified unitized bale of waste material.
  • the size and weight of the bale is obviously dependent upon the nature of the waste material and the size of the compaction chamber, but typically the bale will weigh between one hundred and one thousand kilograms, and it will therefore be too heavy to be manhandled.
  • a baling press is provided with mechanical means for assisting with the removal of the bale from the chamber.
  • a means might take the form of a mechanism for tilting the bale upwardly about its bottom edge adjacent to the open side of the chamber, so as partially to tip or roll the bale so that it may be pulled manually out of the chamber and dropped upon its side onto a flat truck or across stillage (or lift truck) forks previously positioned in front of the opened side of the chamber, whence the bale may be removed.
  • conventional compaction chambers are sometimes slightly tapered, being narrowest at the side opposite to the open side and widest at the open side.
  • bales become jammed during ejection from the chamber, requiring physically tiring and potentially dangerous manual intervention. Also it usually happens that bales which have been tipped onto their sides are unstable and tend to fall over while they are being transported away from the baling press.
  • bales do not always land in a stable attitude upon the flat truck or stillage forks, and during transit away from the baling press they often roll over or slide sideways and fall to the ground, which is both inconvenient and potentially dangerous.
  • an ejection means for ejecting a compressed bale of waste-material from a compaction chamber of a baling press said chamber comprising a floor and side walls defining an opening at the front of the chamber through which the bale may be ejected characterised in that the means comprises a carriage member slideable in guide means formed in the floor and extending linearly of the floor from the rear of the chamber towards said opening, an ejector plate mounted on said carriage member and moveably with the carriage member so as to move a bale towards said opening, a linearly reciprocating push member which in operation of the device is caused to reciprocate continuously, drive means for said push member and means for intermittently transmitting drive from said reciprocating push member to the carriage member so as to cause the carriage member and ejector plate to travel incrementally from the rear of the compaction chamber towards the front.
  • the means for intermittently transmitting drive from the reciprocating push member is caused to reverse direction at the end of the forward path of travel of the ejector plate so as to cause the carriage member and the ejector plate to travel incrementally in reverse direction from the front of the compaction chamber towards the rear of the chamber after ejection of a bale from the compaction chamber.
  • the push member preferably comprises a reciprocating bar and the means for intermittently transmitting drive from the bar to the carriage member comprises a ratchet incorporated in the bar and engageable with a double-sided pawl pivotally mounted on the carriage member.
  • the compaction chamber comprises open-topped box-shaped compaction chamber assembled from side panels, a rear panel, a removable front panel and a floor member.
  • the floor member is divided by a straight linear slot along which a carriage member upon which is fixed an upwardly projecting ejector plate is free to travel, and beneath and parallel with said slot is located a notched or serrated bar member which may be caused by a driving means to reciprocate continuously through a relatively short distance along its linear axis, said carriage member and said notched or serrated bar being supported and guided by fixed linear bearings; and pivoted to the underside of said carriage member is a double-sided pawl member which is so disposed that it may engage with the notches or serrations on the reciprocating notched or serrated bar, the assembly being so proportioned that the carriage is caused to travel in sympathy with the reciprocating bar when it travels in one direction but the pawl rides over the tops of the notches or serrations when the reciprocating bar travels in the opposite direction, thus causing the carriage and the floor member
  • the driving means is an hydraulic cylinder, but optionally it may be a manual lever, or a hydraulically or electrically-driven crank or other linkage.
  • An optional embodiment on the basic design is characterised in that the floor, or one of the side walls, of the compaction chamber, is provided with at least two substantially parallel spaced-apart formers which are raised above the surface of said floor or side walls and which are adapted to form at least two substantially parallel spaced-apart longitudinal grooves in a surface of the bale as the bale is compressed in the baling chamber.
  • the formers are positioned in the floor so when the bale is ejected the bale is in the right orientation for easy removal by mechanical means.
  • the formers comprise raised strips extending longitudinally of the floor or one of said side walls and an upper surface of each strip having a groove extending longitudinally thereof.
  • two of said raised strips are so spaced apart that they coincide with the spacing of the forks of a lift truck.
  • said two raised strips have such a profile that the impressions or indents made by strips in a bale of waste material will coincide with the profiles of the forks of a lift truck.
  • the two strips are substantially equispaced to either side of the centerline of the chamber.
  • the axial centerlines of said raised strips are substantially aligned with banding slits in the front and rear panels of said chamber, and the uppermost surfaces of the raised strips should preferably be provided with recesses whose purpose is to locate and guide banding tapes.
  • a third raised strip may be provided substantially mid-way between said two raised strips, the third raised strip having such a profile that the impression made by said strip in a bale of waste material will facilitate the insertion of a sling for handling said bale by a crane or hoist.
  • the raised strips may be so mounted upon the floor of the compaction chamber that they are mechanically retractable to a folded position wherein the uppermost surfaces of said strips are substantially flush with, or below the surface of the adjacent floor.
  • bales produced in a baling chamber constructed according to this embodiment will be impressed with grooves which will facilitate the ejection of bales onto the forks and/or slings, the grooves further tending to prevent the bales from slipping sideways during handling by a lift truck or a crane or hoist.
  • FIG. 1a and 1b there is seen an open-topped compaction chamber 1 which is constructed according to the invention.
  • the chamber 1 is assembled from fixed side panels 2, a fixed back panel 3, a removable front panel 4, and a carriage member 6 is free to slide along, and is guided by, a linear slot 17 which runs centrally across the floor member 5 between the back panel 3 and the front of the chamber 7.
  • An ejector plate 8 is securely mounted atop the carriage member 6 such that it projects upwardly into the compaction chamber 1.
  • a second linear guideway 9 is located directly beneath the slot in the floor member 5, and a bar 10 is free to slide along and be guided by this second guideway 9, urged to and fro by an hydraulic cylinder 11 which is pivotally mounted upon the base 12 of the machine.
  • a ram 18 of the cylinder 11 is bolted to a bracket 19 is fixed to and depends below the bar 10.
  • the top surface of the bar 10 is provided with regularly spaced notches or serrations 13, and a double-sided pawl member 14, which is suspended from a pivot 15 beneath the carriage 6, is so disposed that it engages with the notches 13 on the surface of the bar 10.
  • Control inputs are communicated to the PLC via an operator's control panel which contains a number of switches for starting or stopping the compaction or ejection systems.
  • a number of sensor switches are also provided as inputs to the PLC to ensure the correct operation of the baling press and the safety of operators.
  • An example of such a sensor switch is the one herein before mentioned to prevent the ejector plate, having ejected a bale and retracted fully from moving incrementally towards the front.
  • Another example of such sensor switches would be those used to determine when the ram was fully extended and when it was retracted. It will be appreciated that a number of alternatives will be available to control the operation of the baling press and/or integrated ejection mechanism. One such alternative would be to replace the PLC with a set of relays connected to achieve the same result.
  • the invention is not limited to the details of the embodiment herein before described, which may be departed from without affecting the claims.
  • the hydraulic cylinder could be replaced optionally by an electrically-driven crank mechanism or by a quick-return linkage, or by a manual lever or an alternative hydraulic cylinder attached to an arm fixed to a transverse shaft projecting beneath one side of the compaction chamber.
  • two identical ejection mechanisms could be fitted side-by-side inside a single compaction chamber, synchronised by a transverse shaft and driven by a single actuator, in order to cope with particularly difficult materials which do not eject easily.
  • FIG. 3a An alternative configuration is disclosed by referring first to Figure 3a, there is seen an empty open-topped box-shaped compaction chamber having two fixed side panels, a fixed back panel 3 and a removable front panel 4 supported upon hinges 106, and a floor 5. It is clear that the compaction chamber will include the ejection means described above. However this is omitted from the drawings to simplify the description of this embodiment. Two substantially parallel spaced-apart raised strips 108 and 110 are fixed to the floor 5, strips 108 and 110 being substantially equispaced to either side of the central axis.
  • slits 111 are provided in the front and back panels 4 and 3, (and would also be present in the ejection plate (not shown)) and grooves 112 are provided centrally along the apices of the raised strips 108 and 110, the respective slits 111 and grooves 112 being aligned when the removable front panel 4 is in its closed operative position.
  • banding straps 114 are laid along the grooves 112, and are allowed to project through the slits 111 in the front and rear panels 4 and 3 respectively and in the corresponding slits in the ejection plate.
  • Loose waste material may then be dropped into the chamber 101 and from time to time, whenever the chamber begins to fill up, a flat-faced plunger or press (not shown) is driven downwardly into the chamber 101 in order to crush and compress the waste material, and the plunger is then withdrawn to its idle position above the chamber in order to allow further loose waste material to be dropped into the chamber 1 on top of that already compacted.
  • a flat-faced plunger or press (not shown) is driven downwardly into the chamber 101 in order to crush and compress the waste material, and the plunger is then withdrawn to its idle position above the chamber in order to allow further loose waste material to be dropped into the chamber 1 on top of that already compacted.
  • the banding straps 114 are passed back through the slits 111 in the front panel 4, across the top surface of the waste material, and out through the slits 111 in the back panel 3.
  • the plunger is then driven downwardly to compress the previously crushed waste and to hold it in this position and prevent it from springing back while the respective ends of the banding straps 114, which are projecting through the slits 111 in the back panel 3, are tied or clipped together.
  • the plunger is then withdrawn, the front panel 4 is removed by hinging it out of the way, and the bale 113 is ejected from the chamber 1 by the ejection means herein before described.
  • FIG. 4a there is seen a side sectional view through an alternative embodiment of the invention, in which the empty chamber 118 is viewed from the back towards the front, the front panel having been removed.
  • Figure 4b shows the same sectional view through the same chamber 118 in which a bale 126 has just been formed substantially in accordance with the procedure described above.
  • the strips 122 and 123 have been retracted into recesses 126 and 127 respectively in the floor 121 of the chamber 118 by a mechanism (not shown), thus exposing the ends of the slots 128 and 129 respectively in the bottom surface of the bale 126.
  • the carriage member 6 is free to move along and is guided by a guideway or linear slot 17 formed by two longtitudal plates 201 and 202 which run from the back to the front.
  • the ejector plate 8 is securely mounted atop the carriage member 6, such that it projects upwardly.
  • the ejector plate is shaped so as to fit between the formers 108 and 110 and to enable it to move freely along the slot 17 formed by plates 201,202.
  • the grooves 112 are provided to each side of the formers facilitate strapping of the bale with wires or the like.
  • guide pins 205 fixed to the bar 10 and extending downwards through linear slots 207 ensure the linear motion of the bar 10.
  • Hooks 206 are provided on the lower front edge of the compaction chamber to facilitate the locking of a pallet truck in position while a bale is ejected from the machine.
  • a detail of the carriage member 6 in figure 6 is shown in figure 7.
  • a pawl 14 is shaped so as to engage grooves 13 in the bar 10 and to facilitate the incremental movement of the carriage hereinbefore described by references to figure 2.
  • Guide wheels 210 ensure that the carriage member 6 will not rise when the bar 10 is effecting movement of the carriage member 6 via the engagement of the pawl 14 with a groove 13.
  • plates 201,202 which extend longtitudally from the front 7 to the rear of the chamber 3 and which form a linear guideway 17 restrict the upper progress of the guidewheels 210.
  • the plates are fixed in position through the use of nuts 214 and bolts 213 which facilitate the removal of plates 201, 202 for maintenance purposes.
  • bales may be produced in a shape such that the bales so produced are more easily and securely handled that heretofore by conventional mechanical handling equipment in particular by fork lift trucks, cranes and hoists.
