Definitions

  • THIS INVENTION relates to a crushing apparatus, with particular reference to a can crushing apparatus.
  • fulcrum-based or lever-actuated can crushing devices are potentially hazardous, in that the moving linkages tend to provide a number of potential digit crushing zones, especially in the case of young children.
  • Manually operable crushing mechanisms also either tend to be over-engineered, on the one hand, or substantially under-engineered on the other in order to minimize the cost of materials.
  • Most manual devices require the compaction mechanism to be reset between each compaction stroke. They are moreover normally characterized by a lack of any ready manner of distinguishing between or separating aluminium and steel or tin-plated cans.
  • a crushing apparatus comprising: a framework having a first end wall defining a first fixed crushing surface; a compression ram mounted for reciprocal motion within the framework and defining a first movable crushing surface; a rotary-to-linear crawl mechanism including at least one toothed rack formation and a complementally toothed pinion formation carried on the rack formation; and drive means for crawling the mechanism in a first linear direction so as to crush an object placed between the first movable and fixed surfaces.
  • the framework includes a second opposed end wall defining a second fixed crushing surface
  • the compression ram defines a second movable crushing surface opposite the first movable crushing surface, with the toothed rack formation extending between the first and second end walls, whereby the drive means is arranged to crawl the pinion formation along the rack formation in a second opposed linear direction to crush an object placed between the second movable and fixed surfaces.
  • continued reciprocating motion of the compression ram is arranged alternatively to crush objects placed successively between the first fixed and movable crushing surfaces and the second fixed and movable crushing surfaces respectively.
  • the drive means may comprise an electrical or similar motor. Typically, it may comprise a manually operable crank arm and handle, or the like.
  • the toothed rack formation comprises a plurality of rack plates in an adjacently stacked arrangement, each rack plate carrying a substantially identical row of teeth; and the complementally toothed pinion formation comprises a matching number of pinion gears in a co-operating adjacently stacked arrangement.
  • rows of teeth on adjacent rack plates and co-operating pinion gears are offset by a matching degree.
  • the degree of offset may be one half pitch.
  • the toothed rack and pinion formations may comprise a common rack or pinion base member respectively, on which are cut one or more mutually offset and adjacent sets of teeth.
  • controlled gear slippage means may be effected by providing a special profile of the intermeshing gear teeth, whereby negligible clearance between the respective addenda and dedenda of the mating teeth of the respective pinion and rack formations is provided.
  • Adjacent sets of teeth may also or alternatively be provided with complementary rolling formations to further reduce wear on the gear train.
  • the rolling formations may comprise side- or spacer- plates running respectively contiguous to or interposed between adjacent rack plates, the side- or spacer- plates being designed to guide complemental rollers arranged to be mounted for rolling movement beside, or within gaps defined between, adjacent, complemental pinion gears.
  • the roller diameter may conveniently correspond to the pitch circle diameter of the pinion gears and rack plates.
  • At least one idler shaft carrying two or more idler pinion formations and at least one drive shaft carrying two or more drive pinion formations for driving the idler pinion formations may typically be journalled within the compression ram, with the framework advantageously defined by two pairs of spaced apart rack formations joining the first and second end walls, each pair being coplanar with a drive pinion formation and an idler pinion formation.
  • the ram may include a magnetic circuit for selectively attracting ferromagnetic cans
  • the crushing apparatus may comprise at least one outer opening adjacent the first end wall for discharging non-ferromagnetic cans and at least one central opening for discharging ferromagnetic cans.
  • the magnetic circuit includes a central magnet, a pair of pole pieces on the opposed first and second moving faces of the ram, and a toggle mechanism for moving the magnet between the first and second pole pieces for selectively attracting cans to and releasing cans from the first and second moving faces of the ram.
  • a crawl mechanism assembly comprising: a mechanism containment formation; a rotary-to-linear crawl mechanism; and drive means for crawling the mechanism linearly within the containment formation.
  • the containment formation may advantageously comprise a framework.
  • the mechanism will comprise at least one toothed rack formation and a * complementally toothed pinion formation carried on the rack formation, the pinion formation defining an axis of rotation.
  • Each of the rack and pinion formations may comprise one or more adjacent sets of teeth, each set of teeth being mutually offset from an adjacent set of teeth in a plane perpendicular to the axis of rotation, whereby the mutually offset sets of teeth on the rack and pinion formations respectively are arranged to intermesh to prevent sideways displacement of the teeth relative to one another.
  • the crawl mechanism includes a pair of parallel spaced apart rack formations and a corresponding pair of spaced apart pinion formations arranged to travel along the rack formations, with the mutually offset interengaging rows of teeth on both the rack formations and the pinion formations serving to ensure that the rack formations are maintained in a parallel configuration at their moving points of contact with the pinion formations.
  • the crawl mechanism assembly will drive a compression ram, a skip or similar carrier or container formation or conveyance, or the like.
  • each of the rack formations of the crushing apparatus is formed from a pair of rack plates of identical length which are fine blanked from a single strip of sheet metal (advantageously a relatively thin gauge mild steel) in such manner that the profiles of the teeth of a first rack plate form the matching profiles of the tooth spaces between the teeth of a second rack plate.
  • the framework thus formed is then treated against corrosion, preferably by tin- dipping.
  • tin acts as a solder flux which in its molten state penetrates even the smallest gaps defined between the rack plates, effectively solder-bonding them together as an integral rack formation as the tin cools; and secondly because of its superior resistance to the corrosive effects of residual cold drink beverages which could be spilled when a beverage can is crushed;
  • a housing for the crushing apparatus is formed out of a number of nominally planar, interlocking components, preferably injection moulded out of a polymer such as glass-filled nylon.
  • the drive shaft assembly is then formed by affixing two pairs of drive pinion gears in spaced apart arrangement on the drive shaft, with the adjacent teeth on each pair of gears being mutually offset by half a pitch.
  • the gears are affixed to the shaft using high current silver soldering;
  • the drive shaft assembly is then treated against corrosion, preferably by tin dipping, before being introduced into the framework through the gap defined by the two opposing pairs of rack formation, with the drive pinion gears intermeshing, in the manner previously described, with the upwardly projecting teeth of the lower pair of rack formations; in the event that the drive shaft assembly includes a manual crank handle, the drive shaft assembly is introduced into the framework at a precisely determined point along the rack formation, and at a pre-determined angle of the crank arm relative to the longitudinal axis of the framework.
  • the crank handle will lie in co- planar orientation to the longitudinal axis of the framework as an aid to effective packaging; the diameter of the holes in the centre of the idler pinion gears is smaller than the outside diameter of the idler shaft.
  • the four idler pinion gears are introduced as offset adjacent pairs into the framework, in a manner such that the teeth at the bottom of the idler gears intermesh with the teeth at the top of the corresponding drive gears, and the teeth at the top of the idler gears intermesh with the corresponding downwardly depending teeth of the upper rack formations.
  • the idler shaft is then introduced between the centres of the opposing pairs of idler pinion gears, and a screw is passed through the centre holes of the gears and then tightened into a pre-threaded hole in each end of the idler shaft.
  • the upper pair of rack formations are therefore spaced and held precisely apart by the idler shaft assembly, the lower pair of rack formations are similarly spaced and held precisely apart by the drive shaft assembly, and each of the vertically opposed pairs of rack formation are spaced apart by the drive shaft and idler shaft assemblies acting perpendicularly in concert with one another; • mating halves of the compression ram, or tup, are then journalled and fixed around the drive and idler shafts in the spaces defined between opposing pairs of pinion gears; cradle members for holding an empty beverage can in the crushing apparatus prior to being crushed are screwed into the framework; and finally inwardly projecting moulded studs on the panels comprising the housing of the apparatus are passed through complemental fixing apertures in the framework and then welded thermally or electronically into

The fer- romagnetic can 76 will be conveyed to a point in which it overlies the gap 70.

  • Step 1 at block 142 of method 140 rack formation 16.1 (or, equally, 18.1, 20.1, 22.1) of Figures 13A and B is formed from a pair of rack plates 16.1 A and 16. IB of identical length which are fine blanked from a single strip of thin gauge mild steel 174.

  • Step 2 at block 144 rack formations 16.1, 18.1, 20.1 and 22.1, formed in accordance with Step 1, are then welded in opposing pairs to first and second rectangular opposed end plates 12.1 and 14.1 spaced apart by the rack formations so as to provide the parallelopipedal cage 176 illustrated in Figure 14, with the teeth (54.1 and 45.1) and (56.1 and 44.1) of each pair of rack formations (16.1 and 22.1) and (18.1 and 20.1), respectively, inwardly opposing one another;
  • Step 3 at block 146 the cage 176 formed per Step 2 is then tin-dipped, thereby both treating the cage against corrosion, and tin-soldering the individual rack plates making up the rack formations 16.1, 18.1, 20.1 and 22.1, together.
  • Step 4 at block 148 a housing 29.1 as illustrated in Figure 15 for the can crusher is formed out of a number of nominally planar interlocking plates 166, 168 and 170, injection moulded out of glass-filled nylon;
  • Step 5 at block 150 four idler pinion gears and four drive pinion gears per can crusher, as used respectively in idler pinion formations 50.1 and 52.1, and in drive pinion formations 40.1 and 42.1, are pressed out of a relatively thin gauge mild steel plate, and the gears are then case-hardened;
  • Step 6 at block 152 the drive shaft assembly 39 illustrated in Figure 16 as part of the crank mechanism 178 is then formed by affixing two pairs of drive pinion gears 40.1 and 42.1 in spaced apart arrangement on the drive shaft 38.1, with the adjacent teeth on each pair of gears being mutually offset by half a pitch.
  • the gears are affixed to the shaft using high current silver soldering;

  • Step 8 at block 156 the drive shaft assembly 39 is introduced, as shown in Figure 17 into cage 176 at a pre-determined point A along rack formation 20.1, and at a predetermined angle B of crank arm 58.1, with the drive pinion gears intermeshing with the upwardly projecting teeth 44.1 and 45.1 of rack formations 20.1 and 22.1 respectively.
  • the precise positioning of the drive shaft assembly 39 ensures that when it is at the extreme of its travel relative to the first end plate 12.1 of the cage 176, the crank handle 58.1 will lie in co-planar orientation to the longitudinal axis of the cage as an aid to effective packaging;
  • Step 9 at block 158 after tin plating, the four idler pinion gears are introduced as offset adjacent idler pinion formations 50.1 and 52.1 into the cage 176, in a manner such that the teeth at the bottom of the idler pinion formations 50.1 and 52.1 intermesh respectively with the teeth at the top of the corresponding drive gear formations 40.1 and 42.1, and the teeth at the top of the idler pinion formations 50.1 and 52.1 intermesh with the corresponding downwardly depending teeth 54.1 and 56.1 of the upper rack formations 16.1 and 18.1 respectively.
  • the diameter of the holes in the centre of the idler pinion formations 50.1 and 52.1 is smaller than the outside diameter of the idler shaft 48.1.
  • idler shaft 48.1 is then introduced between the centres of the opposing pairs of idler pinion formations 50.1 and 52.1, as illustrated in Figure 17, and screws 180 are passed through the centre holes of the idler pinion formations and then tightened into a pre- threaded hole in each end of idler shaft 48.1.
  • the upper pair of rack formations 16.1 and 18.1 are therefore spaced and held precisely apart by the idler shaft assembly, the lower pair of rack formations 20.1 and 22.1 are similarly spaced and held precisely apart by the drive shaft assembly 39, and each of the vertically opposed pairs of rack formation (16.1 and 22.1) and (18.1 and 20.1) are spaced apart by the drive shaft and idler shaft assemblies acting perpendicularly in concert with one another;
  • step 11 at block 162 mating halves of the compression ram, or tup, 30.1 are then journalled and fixed around the drive and idler shafts in the spaces defined between opposing pairs of pinion formations as illustrated in Figure 18;
  • Step 12 at block 164 cradle members 62.1 for holding an empty can in the crusher 10.1 prior to being crushed are attached to the framework 11.1 by means of screws (not illustrated) driven through apertures 182 in rack formations 20.1 and 22.1 into screw housings 184 formed in cradle members 62.1; and
  • Step 13 at block 165 inwardly projecting moulded studs 186 on housing back and front plates 166 and 168, respectively, are passed through complemental fixing apertures 188 in rack formations 16.1 and 18.1, and studs 187 on housing end plates 170, are passed through complemental fixing apertures 188 in framework end plates 12.1 and 14.1, and then welded thermally or electronically into countersunk plastic rivet heads 190, as illustrated in Figure 19 thereby securely affixing the housing plates 166, 168 and 170 to the framework 11.1.
  • Each of the moulded studs 186 and 187 are provided with a spacer boss 192 to ensure that the housing plates stand off from the framework 11.1 by a precise and pre-determined amount when the housing 29.1 is assembled onto the framework 11.1.
  • Removable plugs 194 as illustrated in Figure 15 are provided so that a suitable driver (not illustrated) may be inserted into housing mounting access apertures 172 in housing front plate 168 in order to fix can crusher 10.1 to a suitable mounting substrate, after which the plugs 194 are replaced into apertures 172 for cosmetic appeal.
  • Handle shaft 59.1 is passed through slot 196 in front housing plate 168 before plate 168 is affixed to framework 11.1, whereafter handle 60.1 is screwed onto handle shaft 59.1.
  • the crawl mechanism assembly offers a number of functional and commercial advantages over known conventional crawl mechanisms. The most important of these is the arrangement of offset, essentially adjacent, sets of intermeshing teeth carried on the rack formations, pinion formations, or both. Used in combination with one or more drive shaft and idler shaft assemblies, this arrangement allows the crawl mechanism assembly to dispense with conventional guide means, effectively to provide a moving tie bar in order to maintain spaced apart parallel configuration of rack formations, and to provide a very high level of assurance that the crawl mechanism will not 'de-rail' off the rack formations along which it travels.
  • the special design of the gear teeth so as to offer a planned modicum of slippage, and thereby largely avoid wear on the gear train as it rolls, is a further advantage of the invention, as is the method of constituting rack and pinion formations out of respectively a plurality of rack plates and pinion gears. This allows relatively thinner and softer metal plate to be used, which simplifies pressing and significantly reduces cost.
