Abstract

A container lifting and tipping device for either vehicular or stationary use comprising a bracket (1) mounted to a frame or chassis of a vehicle, compactor, or hopper, an elevating member (4) attached by slides (2) and (5) to bracket (1) tilting member (7) fulcrumed (6) to the elevating member (4) by one end and adjacent to the top of the elevating member (4) a container retaining member (12) automatically activated by means of a roller bearing (13) and ramp (14). Elevation and tilting is controlled and actuated by means of either a hydraulic or pneumatic cylinder (8a).

Description

MULTIPURPOSE CONTAINER HANDLING DEVICE This invention relates to the elevation and tilting of various size plastic and steel containers to effect the emptying of the load therein into a vehicle or stationary receival hopper.

The invention is concerned mainly with the handling of garbage, waste or refuse in domestic, commercial and industrial areas. This first requires the workman to wheel or otherwise place the container (s) to a suitable position where at the workman then operates a control system to enable the invention to elevate the container (s) whilst coincidentally causing the retention of the container (s) to the device to avoid the container leaving the device and falling into the vehicle or stationary receival hopper. The workman then reverses the cycle to have the container(s) untilted and lowered to the ground, coincidentally being released by the retention device.

Tlie invention is not confined to use in the garbage industry as just recounted but it is primarily intended for use in this connection; and so by way of example it will be described herein mainly in terms thereof.

Garbage collection means of the type under consideration are known and in use; the means herein detailed are however more efficient, more speedy, less expensive and less damaging to the lifted container and, moreover, can accept a greater range of containers than others.

This invention provides container pickup and emptying means for either vehicular or stationary use comprising:

(a) A bracket mounted to the fraire or chassis of the compactor, hopper or vehicle,

(b) An elevating member attached by slides to the bracket,

(c) A tilting manber fulcrumed to the elevating member by one end and adjacent to the top of said elevating member and containing a container lifting comb, (d) A container retaining device automatically activated by means of a roller bearing, ball bearing or bushed roller being acted upon by formed ramp system.

(e) Means to firstly elevate the elevation member and secondly rotate the tilting member.

An example of the invention is illustrated in the drawing herewith, perspectively and, to seme extent, schematically.

Referring to the drawing a bracket (1) is fixedly mounted to the frame of the hopper, vehicle chassis or other suitable point. The bracket contains a pair of rectangular, square or circular cross sectioned fanale slides, (2) fixedly mounted and also a fulcrum point (3) to locate the hydraulic or pneumatic cylinder and ram system to power the operation.

The elevating member (4) is carried on two males slides (5) but the positions of the slides (3) and (5) may be interchanged if desireable. The dimensions of the slides and hence the distance of vertical movanent of the elevating member may vary as required by the container to be handled or the receptacle into which the cargo is to be placed.

Fulcrumed (6) at the upper and of the elevating memeber (4) is the tilting member (7) . The geometrical position of fulcrum (6) and the ram fulcrum (8) for ram (8A) is a precise position enabling accurate tilting of the container. Tilting member (7) has fixedly mounted to it a container comb (9) which is formed so as to suit the front lip of all encountered containers. Mounted on two or more fulcrums (10) is a transverse bar (11) carrying the container retaining mariber (12) which is acted upon by one or more roller bearing, ball bearing or roller (13) being in contact with one or more ramp systan (14) . The form or shape of the ramp (14) is such as to force the depression of the container retaining member (12) onto the container lip during the tilt motion thus avoiding the container being lost. The ramp system(s) (14) also acts on roller(s) (13) to allow the container retaining manber (12) to retract from the container lip and allow the container freedom to leave the comb (9) when the tilting member (7) is lowered.

Elevation and tilting is controlled and acted on by a hydraulic or pneumatic cylinder of conventional means with single or multistage operation.

When a container operation is made the workman offers up the container with the lip adjacent to the ccarib (9) , operates the conventional hydraulic control system at which the elevating member (4) rises and the comb (9) engages under the container lip, lifting the container which swings inward until caning against the lower bar (15) . Further upward movanent of the elevating member (4) lifts the container vertically until the member (4) reaches the end of the travel of slides (3) and (5) whereon cranks (15) engage on gate (16) to retain the slides in arm extended position. The continuing ram action is converted to a rotary motion on the tilting mariber (7) by the fulcrums (6) and (8). During the tilting operation roller(s) (13) engage against ramp(s) (14) and act upon the αontainer retaining member (12) causing the manber (14) to depress relative to the tilting member (7) and this to retain the container.

When the cargo leaves the container the hydraulic or pneumatic circuit is reversed leading to the tilting member (7) revolving to the original vertical position the cranks (15) engaged to stop the slides (3) and (5) from moving and during this operation roller (s) (13) are forced by ramp(s) (14) to cause the container retaining member (12) to elevate relative to the tilting member (7) and hence release the container from restraint vertically. Completion of the rotary motion of member (7) causes the cranks (15) to be disengaged.

Further retraction of the hydraulic or pneumatic ram (8A) causes elevating manber (4) to lower in slides (3) and (5) to the position from which the operation was commenced.

Ramp(s) (14) are formed so as to only allow the container to be retained after commencament of the tilting member (7) action thus avoiding premature or prolonged container retention.

Claims

The claims defining this invention are as follows:

Claim 1: In a device for the elevation and tipping of containers, a slide system to allow for varying container heights.

Claim 2: In a device for the elevation and tipping of containers a guide and ramp system to enable retention of the container when in a tipped position.

Claim 3: In a device for the elevation and tipping of containers, a crank system to prohibit lowering of the container before the container is untipped.
