Abstract

A packing and ejecting system for a front or side loading refuse vehicle for packing refuse from a charging hopper into an associated storage body and fully ejecting the refuse from a rearward portion of the storage body without tilting the storage body. A loading device may be used to load refuse or recyclables from the front or side of the vehicle into the charging hopper. A packing and ejecting device may be mounted within the charging hopper without reducing the holding capacity of the charging hopper. The packing and ejecting device includes a substantially hollow cylinder carrier interconnecting crossed pairs of packing cylinders and ejecting cylinders, wherein the extension of the packing cylinders, with the ejecting cylinders retracted, linearly displaces the packer panel and cylinder carrier through a first longitudinal portion of the storage body and extension of both the ejecting cylinders and the packing cylinders, displaces the packer panel through the entirety of the storage body and where the fully retracted cylinders store within a hollow portion of the cylinder carrier.

Claims

1. A combined, packing and ejecting mechanism for a front or side loading, rear discharging, refuse vehicle for packing refuse from a charging hopper into an associated storage body and later ejecting the refuse from the storage body, wherein a loading device loads the refuse into the charging hopper, said packing and ejecting mechanism comprising:

(a) a packer panel having a packing blade and a packer panel recess behind the packing blade positioned within the charging hopper and linearly displaceable along in said refuse vehicle among stowed, packing, and ejecting positions for respectively, receiving charged materials, packing materials into the storage body and ejecting packed materials from the storage body;

(b) a cylinder carrier having hollow portions, wherein the cylinder carrier is adapted for storage within a recess of the packer panel when in the stowed position;

(c) a pair of ejecting cylinders for use in ejecting refuse from the vehicle, each having a first end pivotally attached within the hollow portion of the cylinder carrier and a second end pivotally attached to the packer panel, said ejecting cylinders adapted to nest within a hollow portion of the cylinder carrier when retracted;

(d) a pair of packing cylinders for linearly displacing the packer panel between a stowed and packing position, each having a first end pivotally attached to a base member attached to the forward end of the charging hopper and a second end pivotally attached within the hollow portion of the cylinder carrier, said packing cylinders adapted to nest within a hollow portion of the cylinder carrier when retracted;

(e) wherein extension of the packing cylinders, with the ejecting cylinders retracted, linearly displaces the packer panel through a first longitudinal portion of the storage body and extension of the ejecting cylinders together with extension of the packing cylinders displaces the packer panel through the remainder of the storage body; and

(f) wherein upon full retraction, all cylinders nest entirely within said packer panel recess such that the packer panel in a fully retracted position fits cleanly against a vertical hopper wall.

2. The refuse vehicle as recited in claim 1, further including a telescoping follower panel attached to a top portion of said packer panel.

3. The packing and ejecting mechanism as recited in claim 1, wherein the packing cylinders and the ejecting cylinders are vertically offset and fold together when said packing cylinders and said ejecting cylinders are retracted to form collapsed X patterns when in the stowed position.

4. The refuse vehicle as recited in claim 1 wherein each of said base members is positioned in the charging hopper proximate a forward corner thereof.

5. A combined, packing and ejecting mechanism for a front or side loading, rear discharging, refuse vehicle for packing refuse from a charging hopper into an associated storage body and later ejecting the refuse from the storage body, wherein a loading device loads the refuse into the charging hopper, said packing and ejecting mechanism comprising:

(a) a packer panel having a packing blade and a packer panel recess behind the packing blade positioned within the charging hopper and linearly displaceable along in said refuse vehicle among stowed, packing, and ejecting positions for respectively, receiving charged materials, packing materials into the storage body and ejecting packed materials from the storage body;

(b) a cylinder carrier having hollow portions, wherein the cylinder carrier is adapted for storage within a recess of the packer panel when in the stowed position;

(c) a pair of ejecting cylinders for use in ejecting refuse from the vehicle, each having a first end pivotally attached within the hollow portion of the cylinder carrier and a second end pivotally attached to the packer panel, said ejecting cylinders adapted to nest within a hollow portion of the cylinder carrier when retracted;

(d) a pair of packing cylinders for linearly displacing the packer panel between a stowed and packing position, each having a first end pivotally attached to a base member attached to the forward end of the charging hopper and a second end pivotally attached within the hollow portion of the cylinder carrier, said packing cylinders adapted to nest within a hollow portion of the cylinder carrier when retracted;

(e) a telescoping follower panel attached to a top portion of said packer panel;

(f) wherein extension of the packing cylinders, with the ejecting cylinders retracted, linearly displaces the packer panel through a first longitudinal portion of the storage body and extension of the ejecting cylinders together with extension of the packing cylinders displaces the packer panel through the remainder of the storage body; and

(g) wherein upon full retraction, all cylinders nest entirely within said packer panel recess such that the packer panel in a fully retracted position fits cleanly against a vertical hopper wall.

6. The refuse vehicle as recited in claim 5, wherein the base members are positioned in the charging hopper proximate a forward corner of the charging hopper.

7. The packing and ejecting mechanism as recited in claim 5, wherein the packing cylinders and the ejecting cylinders are vertically offset and fold together when said packing cylinders and said ejecting cylinders are retracted to form collapsed X patterns when in the stowed position.
