Complete Specification for the invention entitled: The following statement Is a full description of this invention, Including the best method of performing it known to me:- CONTAINER TILTING DEVICE.
‘4:2 R7 1 S/ 12 Q 4 CONTAINER TILTING DEVICE *coo 0 0
SCOV
4 *6 4 4 44 A 0′ 4 4 4444° 44 4 4| 04 4 4 4 04 This invention relates to tilting devices for containers whereby the emptying of the container is facilitated.
In the past it has been common to provide container raising and container tilting apparatus wherein the motive power for the tilting or raising operation was hydraulic or pneumatic. The construction of such devices was expensive and complicated by the use of hydraulic or pneumatic cylinder arrangements and the pipe and valve installations associated therewith. It was rccognised that there was a need for a simple and relatively inexpensive device to replace the devices as described above.
In most instances the containers to be used with the devices had to be placed thereon by a forklift truck. It was the ready availability of such a power source that has given rise to the present invention which achieves the above objectiveo of simplicity and economical construction.
Broadly, the invention can be said to provide a container tilter comprising a(base, a container support mounted on the base so as to be pivotally mcvable between a rest position and a tilted position, link means pivotally connected to said support and extending between said support and track means on said base, said link means being adapted for engagement by an external power source for raising and lowering said link means and the container suppcrt connected thereto, at least one elongated prop foG said support, said prop being pivotally connected to tho, support and provided 2 with a latch which when engaged secures tc prop to the support in an inoperative position, said latch being manually engagable when the support is inclined at an angle greater than a predetermined angle above said rest position and being released automatically when said support is lowered to an angle less than said predetermined angle by engagement of a part of said latch with said base, a socket on the base lying in a path which will be follcwed by a socket engagable part of said prop when said prop is o o’ unlatched and said support is moved to said tilted position o o° with resultant automatic engagement between said socket and 0 o0 said prop part.
The invention in a presently preferred form is °0 described below with reference to the accompanying drawings in which:- 0o 0 °O Fig.l is a schematic side elevation of a tilting device 0 0 J according to the invention when in its rest position, o” 9 o Fig.2 is a view similar to Fig.l of the tilting device when o 0 in the operative position, S, Fig.3 is an enlarged fragmentary view of the prop assembly to releasably maintain the tilting device in the Fig.2 condition, but as it would be for the Fig.l rest condition, Fig.4 is a view similar to Fig 3 with the prop assembly in following a path which will cause automatic engagement of the prop assembly as the container support is tilted and is a view similar to Fig.3 showing the prop assembly latched for lowering of the container support from the Fig.2 condition, i; c- -3- The tilting device as propos ed comprises a stand I with front and rear legs pairs 2 and 3 and top and bottom longitudinal rails 4 and 5 respectively join the leg pairs 2 and 3. There are cross rails 6 Joining the longitudinal rails 4 and 5 and rigidify the frame 1. There are 4inwardly facing channels 7 at opposite sides of the frame to provide substantially vertical tracks for a reason to be described.
A lifter, indicated generally 8, comprises a Pair of tyne receiving channels 9 interlinked and provided with Swheels 10 which run in the track forming channels 7. It is to be understood that the lifter described is of a 0 00 fundamental form and additional or alternate means in place o f the channels 9 fitted with wheels 10 can be provided for engagement and operation by the tynes of a forklift truck.
In the lowered position the chai~npls 9 rest on transverse 0 Ov rails 6a and 6b.
0 0 There are bearing blocks 11 on “,he top rails 4 and a C01 container cradle 12 is mounted on the frame 1 through stub axles 13 engaged in the bearing blocksi 11, whereby the cradle can be pivoted relative to the frame 1. The cradle ,s illustrated is cf P. form well known for use with a container C known as Pallecon (Registered Trade Mark) wherein the container has a front lower door which is openable to allow discharge of free flowing material from the container into a chute 14 (mounted on the cradle) whereby the container contents can be directed to another corntainer or a use location. The cradle comprises uprights 12a and a pallet support platform or frame 12b interlinked

The cradle as illustrated is provided with a bag extractor device 15 of the type used to withdraw a plastic liner bag from the container as the contents of the bag are discharged into the chute thereby ensuring substantially all of the contents of the bag will be discharged into the chute 14. This form of bag extractor is known in the industry.
In Fig. 1 it will be seen that there is a link means comprised of two links 16 pivotally connected at their ends to the bottom of the cradle 12 at 17 and to the lifter 8 at 18. In Fig.2 it will be seen that the result of raising the lifter 8 by a fork lift truck is to elevate the cradle 12 to the inclined position shown.
The cradle is maintained in one of several possible elevated positions by a prop assembly comprised of a pair of arms 19 respectively pivotally connected at first ends to the underface of the cradle 12 at 20 and interconnecea by a bar 21 at the other ends. There are pairs of stops 22 and 23 on the upper faces of the top rails 4 for engagement in pairs by the bar 21 thereby to support the cradle at the required inclination, as is hereinafter described. It is to be understood that more than two stop positions can be provided. There is latch means 24 to retain the prop assembly in close relationship with the cradle, as shown in as will now be described.
Referring to Fig 2 which illustrates the cradle inclined after elevation of the lifter as described above by a fork lift truck, it will be seen that the bar 21 is located behind the stop 23 and is prevented from rearward movement by the abutment member(s) 25. As will be understood this is achieved automatically as the lifter 8 is raised allowing the bar 21 to slide along the tops of the top rails 4 from the position shown in Fig.l, up the inclined face of the first stops 22 over the peak thereof and to then drop behind the stops 22. As the lifter is raised further the bar 21 will slide up the inclined face of the stops 23 over the peaks thereof and then drop o” therebehind.
o° The Fig.2 position is completed by lowering the lifter 0 o 8 until the bar 21 engages the rails 4. The fork lift 0 4 0 .o tynes are then removed from the lifter channels 9. The arrangement is such that waen in the last set of stops the arms 19 will be inclined in the direction as shown in Fig.2 ,io ensuring a locking condition for the bar 21 with the stops.
0 00 It will be noted that the latch means comprises a bent arm 26 pivoted at 27 on the arm 19, two latch means may be provided but one is adequate for most purposes. Referring to Fig.3, the cradle 12 is in its horizontal position and the latch assembly is shown in the inoperative position with the positioning tension spring 28 under tension and the end 29 of the arm 26 of the latch resting upon the bearing surface 30. The bearing surface 30 can be the top of a cross bar 6. Fig.4 shows the cradle in a partly raised position and it will be seen that the end 29 of the arm 26 still rests upon the surface 30 but the arm 26 has adopted a more upright position due to the action of the spring 28 i l i ii i i.”.iM niii c 6 tending to rotate the arm 26 anti-clockwise. In Fig.2 the position of the arm 26 when the cradle is elevated is clearly shown.
When the cradle is to be lowered, the fork lift truck tynes are engaged in the lifter 9 and it is elevated sufficiently to allow the bar 21 to be disengaged from behind the stops 23. The fork lift truck operator then alights and hand raises the prop assembly to the position shown in Fig.5. As will be understood the positioning of o the latch and the hooked end 31 thereof is such that as the oa prop is brought into close proximity to the cradle the 0 00 sloping front face of the hooked end 31 rides over the latch P 0 0.00 pin 32 on the cradle and latches thereover due to the pull 00 0 0 0 of the spring 28, see Fig.5, the spri.g 28 normally holding the hooked arm against the stop 31a.
00 As the lifter is lowered and the cradle pivots to the Fig.l position the end 29 of the armn 26 will engage the S surface 30. As can be appreciated from the positional relationship of the components as shown in Figs.3 and 5 the hooked end of the latch 26 will be caused to release the pin 32 before the Fig.3 condition is reached. It will be readily understood the whilst the arcs of travel of the pin 32 and the hooked end of the arm 26 will intersect as the lifter is raised the next time, the intersection will occur after the pin 32 is at an elevation above hooked end of the latch member and so inter-action between the pin 32 and the hooked end will not occur.
