Definitions
- This invention relates to container handling apparatus in particular to apparatus for lifting and tipping containers, primarily used for the transport and disposal of waste and waste products, in order that their contents can be discharged into a collecting vehicle.
- An object of the invention is to provide a mechanism for lifting the said containers and tipping them such that their contents are discharged into the loading hopper of the said collecting vehicle.
- a tipping body is pivoted by a tipping ram or first drive means about a tipping axis.
- a bin support is movable vertically relative to the body by another ram or second drive means between bin released and bin secured positions and during this movement the bin support slides within the body.
- the bin support includes an arm which engages under the bin when lifted.
- the apparatus further includes securing members which hook over the upper end of a bin when the bin is lifted and the securing members are hinged to move between a stowed position and an operative position, in the stowed position the securing members being folded forwards in the direction of travel of the associated vehicle.
- the first part of claim 1 is based on this document.
- a securing member in the form of a gripper arm is provided which in the inoperative position is below and to the side of the operative position and the movement is effected by reciprocal drive means.
- the gripper arm includes a resilient hook member movable from a receiving position for receiving the upper end of the container towards a gripping position against the bias of spring means.
- the tipping body or frame is pivotable about a pivot which lies to the side of the plane of the. plane of the tipping frame opposite the container and at substantially the level of the upper end of the frame so that as the first drive means is operated the container rises as it pivots about the pivot.
- the apparatus may include linkage means between the second drive means and the tipping body or frame and the linkage means may comprise a scissors linkage and movement of the second drive means results in relatively greater movement of the lift carriage than the drive means.
- the links of the pair are each cranked with one end connected to the lift carriage and the other end to the tipping frame, the pivot between the links being connected to a piston and cylinder constituting said second drive means.
- the gripper means may include gripper fingers mounted on the lift carriage and an abutment on the tipping frame whereby upon lifting of the lift carriage relative to the tipping frame the container is engaged by the fingers and is gripped between said fingers and said abutment and the lift arm may be movable out of said outwardly extending operative position to an inoperative position.
- a commercial vehicle chassis 1 is fitted with a body 2, on the rear of which is mounted a collecting hopper 3, in which, normally, is a powered compacting mechanism (not shown). Provision exists for loading the rear collecting hopper with material over a rearmost rail 4. Mounted on the rail 4 is the lifting/tipping mechanism 5 and, above the collecting hopper 3, is mounted a canopy 6.
- the lifting/tipping mechanism 5 comprises a pair of pivot brackets 7 mounted on the rear rail 4 and projecting rearwardly and upwardly from the rail. Pivotally mounted on these brackets 7 by pivot pins 8 is a tipping frame 9 comprising a top crossmember 9A and a lower crossmember 9B which are interconnected by two upright side members 9C. Pivotally connected to the tipping frame 9 by pivot pins 10 are the piston rods of piston-in-cylinder devices 11, the lower ends of the cylinder being pivotally mounted by pivot pins 12 on mounting brackets 13 attached to the loading hopper.
- Extension of the piston-in-cylinder devices 11 causes the tipping frame 9 to rotate about the pivot pins 8 from an initial position A, shown in full lines, corresponding to the initial lift position, to a position A', shown in dotted lines, corresponding to the final tipped position.
- a lift carriage 15 comprises a pair of substantially horizontal crossmembers 15 and 16 interconnected by two upright channel sections 17, the channel sections being disposed in such a manner that each partially encloses one of the upright side members 9C of tipping frame 9, thus permitting the lift carriage to slide up and down the tipping frame between an initial position B (Fig. 2), shown in full lines and a final lift position B', shown in dotted lines.
- Anti-friction pads 18 are preferably fitted between the inner faces of the channel sections 17 and the tipping frame upright side members 9C to provide a smooth sliding action.
- Means are provided, preferably in the form of a piston-in-cylinder device 19 (Fig. 3) to power the movement of the lift carriage 14 along the tipping frame 9.
- the range of containers to be handled vary in volume and height, thus the lift carriage 14 must have a range of movement to enable it to engage with containers at varying heights. Some additional travel is also required to cater for uneven ground conditions and vehicle suspension deflection. If a piston-in-cylinder device were used to provide a direct drive for this carriage stroke, then its overall length would be comparatively large; and this length would be reflected in the overall height of the tipping frame 9. If a frame 9 becomes too tall then the ground clearance behind the vehicle is diminished and the top rail 4 becomes too high to permit convenient hand loading of bagged rubbish and conventional domestic dustbins.
- an amplifier linkage is provided as the interconnecting mechanism between the piston-in-cylinder device 19 and the lift carriage 14.
- This amplifier linkage has the added advantage of converting a single actuator input into a balanced dual output, thus providing a square, even lift to the lift carriages.
- the piston-in-cylinder device 19 is rigidly mounted at the lower end of its cylinder on the lower crossmember 98 of the tipping frame 9, with the piston rod extending upwardly.
- Adjacent to the intersection of the tipping frame uprights 9C and top crossmember 9A are fitted plates 20 in which is a substantially horizontal slot 21.
- Engaging with the slots 21 are rectangular bearing blocks 22, the bearing blocks being free to move along the slots 21.
- Pivotally mounted on the centre of the bearing blocks 22, through pivot pins 23, are cranked lines 24, the links 24 extending transversely across the tipping frame.

- a container 31 being a larger volume than a container 32.
- the container 31 is pushed on its castor wheels up to the rear face of the lift/tip mechanism to position C shown in full lines.
- the piston-in-cylinder device 19 is energised and the lift carriage rises up the tipping frame 9.
- the fingers 29 engage with the container lifting rail 30 and lift the container upwards until the top face of the rail 30 abuts a flange 33 on the top crossmember 9A of the tipping frame 9, the container then having reached position C'.

Abstract
Description
- This invention relates to container handling apparatus in particular to apparatus for lifting and tipping containers, primarily used for the transport and disposal of waste and waste products, in order that their contents can be discharged into a collecting vehicle.
- Conventionally there exists a range of containers with volumes of 120, 240, 600 and 1,100 litres, which have hitherto been used extensively on the Continent, and conventionally there exists refuse collecting vehicles normally with a rear collecting hopper, which may contain a mechanism for compacting the waste loaded into the hopper and for compressing it into the main body. An object of the invention is to provide a mechanism for lifting the said containers and tipping them such that their contents are discharged into the loading hopper of the said collecting vehicle.
- In GB-A-2092094 there is disclosed apparatus for tipping bins and refuse containers in which a tipping body is pivoted by a tipping ram or first drive means about a tipping axis. A bin support is movable vertically relative to the body by another ram or second drive means between bin released and bin secured positions and during this movement the bin support slides within the body. The bin support includes an arm which engages under the bin when lifted. The apparatus further includes securing members which hook over the upper end of a bin when the bin is lifted and the securing members are hinged to move between a stowed position and an operative position, in the stowed position the securing members being folded forwards in the direction of travel of the associated vehicle. The first part of
claim 1 is based on this document. - In the apparatus according to the invention a securing member in the form of a gripper arm is provided which in the inoperative position is below and to the side of the operative position and the movement is effected by reciprocal drive means. By this arrangement the handling apparatus can be swiftly adapted for tipping relatively large containers using a powered arrangement operation of which moves the arm from an inoperative position to an operative position in one continuous movement.
- Preferably the gripper arm includes a resilient hook member movable from a receiving position for receiving the upper end of the container towards a gripping position against the bias of spring means.
- Conveniently the tipping body or frame is pivotable about a pivot which lies to the side of the plane of the. plane of the tipping frame opposite the container and at substantially the level of the upper end of the frame so that as the first drive means is operated the container rises as it pivots about the pivot.
- The apparatus may include linkage means between the second drive means and the tipping body or frame and the linkage means may comprise a scissors linkage and movement of the second drive means results in relatively greater movement of the lift carriage than the drive means.
- In one arrangement the links of the pair are each cranked with one end connected to the lift carriage and the other end to the tipping frame, the pivot between the links being connected to a piston and cylinder constituting said second drive means.
- The gripper means may include gripper fingers mounted on the lift carriage and an abutment on the tipping frame whereby upon lifting of the lift carriage relative to the tipping frame the container is engaged by the fingers and is gripped between said fingers and said abutment and the lift arm may be movable out of said outwardly extending operative position to an inoperative position.

- Fig. 1 is a side elevation of a refuse collecting vehicle with a lifting/tipping mechanism fitted to the rear collecting hopper,
- Fig. 2 is a side elevation of the lifting/tipping mechanism of Fig. 1,

- Fig. 3 is a rear view of the lifting/tipping mechanism of Figs. 1 and 2,
- Fig. 4 is a rear view, corresponding to Fig. 3, of a lifting/tipping mechanism to which is added container engaging devices, some of the constructional features of Fig. 3 having been omitted for clarity,
- Fig. 5 is a side elevation of the mechanism of Fig. 4,
- Fig: 6 is a plan view of the mechanism of Fig. 4,
- Fig. 7 is a section on the line 7-7 in Fig. 4,
- Fig. 8 is a longitudinal cross-section through part of the mechanism of Figs. 4-7,
- Fig. 9 is a side elevation of another part of the mechanism of Figs. 4-7, and
- Fig. 10 is a partially sectioned end view of the part shown in Fig. 9.
- Referring to the drawings and firstly to Figs. 1-3 a
commercial vehicle chassis 1 is fitted with abody 2, on the rear of which is mounted acollecting hopper 3, in which, normally, is a powered compacting mechanism (not shown). Provision exists for loading the rear collecting hopper with material over arearmost rail 4. Mounted on therail 4 is the lifting/tipping mechanism 5 and, above the collectinghopper 3, is mounted acanopy 6. - The lifting/
tipping mechanism 5 comprises a pair ofpivot brackets 7 mounted on therear rail 4 and projecting rearwardly and upwardly from the rail. Pivotally mounted on thesebrackets 7 bypivot pins 8 is a tippingframe 9 comprising atop crossmember 9A and alower crossmember 9B which are interconnected by twoupright side members 9C. Pivotally connected to the tippingframe 9 bypivot pins 10 are the piston rods of piston-in-cylinder devices 11, the lower ends of the cylinder being pivotally mounted bypivot pins 12 onmounting brackets 13 attached to the loading hopper. Extension of the piston-in-cylinder devices 11 causes the tippingframe 9 to rotate about thepivot pins 8 from an initial position A, shown in full lines, corresponding to the initial lift position, to a position A', shown in dotted lines, corresponding to the final tipped position. - A
lift carriage 15 comprises a pair of substantiallyhorizontal crossmembers upright channel sections 17, the channel sections being disposed in such a manner that each partially encloses one of theupright side members 9C of tippingframe 9, thus permitting the lift carriage to slide up and down the tipping frame between an initial position B (Fig. 2), shown in full lines and a final lift position B', shown in dotted lines. Anti-friction pads 18 (Fig. 2A) are preferably fitted between the inner faces of thechannel sections 17 and the tipping frameupright side members 9C to provide a smooth sliding action. - Means are provided, preferably in the form of a piston-in-cylinder device 19 (Fig. 3) to power the movement of the
lift carriage 14 along the tippingframe 9. The range of containers to be handled vary in volume and height, thus thelift carriage 14 must have a range of movement to enable it to engage with containers at varying heights. Some additional travel is also required to cater for uneven ground conditions and vehicle suspension deflection. If a piston-in-cylinder device were used to provide a direct drive for this carriage stroke, then its overall length would be comparatively large; and this length would be reflected in the overall height of the tippingframe 9. If aframe 9 becomes too tall then the ground clearance behind the vehicle is diminished and thetop rail 4 becomes too high to permit convenient hand loading of bagged rubbish and conventional domestic dustbins. Therefore an amplifier linkage is provided as the interconnecting mechanism between the piston-in-cylinder device 19 and thelift carriage 14. This amplifier linkage has the added advantage of converting a single actuator input into a balanced dual output, thus providing a square, even lift to the lift carriages. - The piston-in-
cylinder device 19 is rigidly mounted at the lower end of its cylinder on the lower crossmember 98 of the tippingframe 9, with the piston rod extending upwardly. Adjacent to the intersection of the tippingframe uprights 9C andtop crossmember 9A are fittedplates 20 in which is a substantiallyhorizontal slot 21. Engaging with theslots 21 are rectangular bearingblocks 22, the bearing blocks being free to move along theslots 21. Pivotally mounted on the centre of thebearing blocks 22, throughpivot pins 23, are crankedlines 24, thelinks 24 extending transversely across the tipping frame. At a median point of the links 24 apivot pin 25 engages the two links and is secured to the upper end of the piston rod of the piston-in-cylinder device 19. On eachlink 24 at the opposite end to thepivot pins 23 are mountedspherical rod ends 26 which in turn are connected viascrewed rods 27 and lower spherical rod ends 28 to thelower crossmember 16 of thelift carriage 14. Thus, as the piston-in-cylinder device 19 is extended or retractedpivot pin 25 rises to position 25' and falls on a substantially vertical line, thetransverse links 24, working with a scissor type action, pivot aboutpivot pins bearing blocks 22 slide to and fro in theirslots 21 and the lift carriage, via the drive from the spherically endedrods 27, rises up to positions 15', 16' or runs down the tippingframe 9. Due to thelinkage 24 the movement of the piston rod ofdevice 19 is amplified in effecting movement of thelift carriage 14. - Arranged along the upper face of the lift carriage
top crossmember 15 is a row of upwardly pointing fingers 29 (only two of which are shown in Fig. 3), the upper profile of the fingers being such as to permit engagement with a formed inverted channel lifting rail 30 (Fig. 2) on the upper front lip of the container to be emptied. - In Fig. 2 two alternative sizes of container are shown, a
container 31 being a larger volume than acontainer 32. In operation thecontainer 31 is pushed on its castor wheels up to the rear face of the lift/tip mechanism to position C shown in full lines. The piston-in-cylinder device 19 is energised and the lift carriage rises up the tippingframe 9. As the lift carriage rises thefingers 29 engage with thecontainer lifting rail 30 and lift the container upwards until the top face of therail 30 abuts aflange 33 on thetop crossmember 9A of the tippingframe 9, the container then having reached position C'. The piston-in-cylinder devices 11 are then energised and the assembly of tippingframe 9,lift carriage 14 and thecontainer 31 rotate as a whole aboutpivots 8 to the tipped position C", an abutment rail (not shown) engaging with the lower front face of the container. Reversing the procedure will return the container to the ground. - The
larger volume container 31 is fitted with alid 38 which is, when viewed from the side, of curved profile and is pivoted to the container body bypins 34. The lid has a pair of outwardly extendingabutments 35. Carried, pivotally, on thecanopy 6 is a frame assembly 36 (Fig. 2) comprising two spaced, elongated hook-shaped side members 36A, interconnected by a crossbar, and pivoting aboutpins 37. Themembers 36A are biased by springs (not shown) towards an anticlockwise direction, such movement being limited by abutments (not shown) so that they extend substantially vertically downwards. As thecontainer 31 rotates from the lifted position C' to the tipped position C" thelid abutments 35 engage with thehooks 36A of theframe 36 causing thelid 38 to rotate aboutpins 34 into an open position D. - In an alternative method of location of the vertical slides between the tipping frame and the lift carriage, as described, the lower end of the lift carriage could be pivotally mounted on a sliding block engaging the tipping frame upright 9C and the upper end of the
lift carriage 14 could be connected to thetipping frame 9 via a pair of pivoted links such that when viewed from the side a 'slider crank' mechanism is formed. This mechanism would enable thefingers 29 to rise in a curved arc, lifting and drawing in the container to its abutment on the tipping frame. - ltwill be appreciated thatthe
liftfingers 29 on the lift carriage may be replaced, modified or augmented by additional features to enable containers of various forms to be handled. - Reference is now made to Figs. 4-10 in which one such modification is made. In the Figs. 4-10 embodiment the main lifting-tipping mechanism as described in relation to Figs. 1-3 remains, although parts are omitted from Figs. 4-10 for clarity. In Figs. 4-10the same reference numbers are used for the same parts as shown in Figs. 1-3.
- The arrangement of Figs. 4-10 is to enable the mechanism to operate with a form of refuse container consisting of a cylindrical body having dimensions of the order of one metre in diameter and one and a half metres high. Such containers are designed to be lifted by engagement of lifting arms under the container, the upper edge of the container being gripped during lifting.
- In Figs. 47 there is shown lifting arms or
forks 50 for engaging under acylindrical container 39, the full lines indicating the forks in a lifted position. - The
forks 50 are generally L-shaped each having a horizontally-directedportion 43 and a circular section vertical portion orshaft 44. Theshafts 44 are each free to rotate and to move axially inbearings 46 located in the horizontallower cross members 9B of thetipping frame 9. The upper ends of theshaft 44 are connected by bearingassemblies 47 totrunnion assemblies 45 which are rigidly mounted on thecarriage lift assembly 14. Thus theshafts 44 are raised and lowered by vertical movement of the lift carriage, as described in relation to Figs. 1-3, and theportions 43 are raised and lowered with theshafts 44. - The
horizontal portions 43 are movable from the rearwardly-extending full line position (Fig. 7) towards a parked, inoperative position 43'. In the rearwardly-extending position theportions 43 abut each other oversurfaces 48 and in the inoperative position 43' over surfaces 49. - The
forks 50 are moved between the inoperative and operative positions manually by means of a linkage (not shown) or, under power, by a piston and cylinder (not shown). - At the upper end of the tipping frame are mounted two
vertical shafts 42 which each rotate and move axially within thevertical legs 9C of theframe 9. The upper ends of theshafts 42 each carry a rigidly mounted pick uparm 40 which extends horizontally and which pivotally supports hooks 41. Thearms 40 can adopt an operative, raised position extending rearwardly (shown in full lines) or a sideways-extending lowered position 40' in which the arms are inoperative. - Fig. 8 shows the means by which each
arm 40 is raised, lowered and rotated. Theshaft 42 locates in a bore of aguide tube 52 mounted in theside member 9C of theframe 9. Ahelical slot 58 is formed at the lower end of thetube 52 and apin 51 carried on theshaft 42 locates in theslot 58 so that when theshaft 42 is moved along and relative to thetube 52 the shaft also rotates relative to thetube 52. The lower end of theshaft 42 carries anabutment ring 54 which abuts the lower end of thetube 52 when the shaft is in its raised position. Theshaft 42 is moved along thetube 52 by a double- acting piston andcylinder device 56 which at one end is fixed to theshaft 42 by apin 55 and is secured at its other end to theside frame member 9C by apivot bracket 57. - Extension of the piston in the
cylinder 56 causes theshaft 42 to cause thearm 40 to rise and move from a lowered position to a raised and rearwardly directed, operative position. - Figs. 9 and 10 show means for gripping the upper edge of a
container 39, such means including ahook 41 having a downwardly-directedtang 41A. Thehook 41 is pivotally connected to eacharm 40 through apivot 60 and is free to move from a full line position, as shown, to position 41' and is biased towards position 41' by atension spring 61 which interconnects thehook 41 and thearm 40. As shown, a top edge of thecontainer 39 is engaged with thehook 41, the hook being moved to the full line position against the spring bias during a container lifting operation. - To lift and tip a
cylindrical container 39 theforks 43 are moved to their operative position from position 43' and thecylinder 19 is retracted to lower the forks towards the ground via thebearing 47. - The
cylinders 56 are then extended to cause thearms 40 to lift and rotate from position 40'towards the operative position, thehooks 41 being in position 41' under the action of thespring 61 to receive the top edge of thecontainer 39. - The
container 39 is mounted onwheels 59 and is pushed towards the lifting/tipping mechanism until avertical portion 41A of the arms is engaged. - The
cylinder 19 is extended to lift theforks 43 and the forks engage under the base of thecontainer 39 to lift the container until the top edge engages thehooks 41 and causes the hooks to pivot aboutpivots 60 until further pivoting is prevented by abutment of faces 63. Thecontainer 39 is now firmly locked between thehooks 41 and theforks 43 and can be tipped, as described in relation to Figs. 1-3, towards the tipped position C" by extension of thecylinders 11. After emptying of the container the container is lowered and released by the reverse procedure. - Although there is described and shown lifting and tipping apparatus for use on vehicles it will be appreciated that the apparatus can equally be applied to static installations in which containers are discharged into a larger receiving hopper associated with a packing mechanism.
