Patent Application
20150093220
The present disclosure relates to front loading refuse vehicles and, more particularly, to an intermediate container that includes a side arm that is mounted partially inside the intermediate container.
Various types of intermediate cans or containers have been disclosed in the art. U.S. Pat. Nos. 8,496,427; 8,092,141; 7,553,121; and 7,210,890 are examples of such intermediate containers. These intermediate containers are known in the art as “Curotto Cans”. Generally, Curotto cans include a side loading robotic arm at the rear or front of the container. This arm is movable on a slide that is secured on an outer wall of the container. While these types of side loading arms on intermediate containers work satisfactorily for their intended purposes, designers strive to improve the art.
Accordingly to the present disclosure, an intermediate container is provided with a sliding arm positioned within the container. The sliding portion of the arm is positioned within a pocket or a channel within the container. Generally, the side arm is positioned on the rear wall of the container.
Accordingly to a first aspect of the disclosure, a refuse collection container comprises a bottom, a front wall, a rear wall and a pair of side walls between the front and rear walls to form an overall box shaped container. A movable arm is movably mounted on the container. The movable arm grasps refuse cans and dumps the refuse cans into the container. A slot is formed in the rear wall. The movable arm is positioned adjacent the slot. A slide portion of the arm is positioned on the inside of the container. The arm slide moves laterally (horizontally) in and out of the container to move the arm to grasp and return the refuse can. A portion of the arm projects through the wall and is on the outside of the container. An arm slide is positioned inside the container adjacent the slot. A grasping mechanism is positioned outside of the container. A channel is formed inside of the container to receive the slide mechanism. A protecting cover is coupled with the rear wall surrounding the arm slide.
According to a second aspect of the disclosure, a refuse vehicle comprises a chassis with a cab. A permanent container is coupled with the chassis. A front loading fork is coupled with the chassis. An intermediate container is mounted on the front loading fork. The intermediate collection container comprises a bottom, a front wall, a rear wall and a pair of side walls between the front and rear walls to form an overall box shaped container. A movable arm is movably mounted on the container. The movable arm grasps refuse cans and dumps the refuse cans into the intermediate container. A slot is formed in the rear wall. The movable arm is positioned adjacent the slot such that a slide portion of the arm is positioned on the inside of the container. The slide portion moves laterally in and out of the container to move the arm to grasp and return the refuse can. A portion of the arm projects through the wall and is on the outside of the container. An arm slide is positioned inside the container adjacent the slot. A grasping mechanism is positioned outside of the container. A channel is formed inside of the container to receive the slide mechanism. A protecting cover is coupled with the rear wall surrounding the slide.
Further areas of applicability will become apparent from the description provided herein. The description and specific examples in this summary are intended for purposes of illustration only and are not intended to limit the scope of the present disclosure.
The drawings described herein are for illustrative purposes only of selected embodiments and not all possible implementations, and are not intended to limit the scope of the present disclosure.
Turning to the figures, an intermediate container is illustrated and designated with the reference numeral 10. The intermediate container 10 is positioned on the front loading forks 12 of a refuse collection vehicle 14. The refuse collection vehicle 14 includes a cab 16 and a chassis 18 with a stationary container 20 mounted on the chassis 18 of the vehicle 14. The stationary container 10 has an opened hopper 22 that receives refuse from the intermediate container 10.
The intermediate container 10 has an overall box shape with a front wall 24, a rear wall 26, sidewalls 28, 30, a bottom 32 and an open top 34. A refuse can be positioned into the intermediate container 10 through the open top 34. The refuse remains in the intermediate container 10 until it dumped into the hopper 22. Also, the intermediate container 10 includes a pair of channels 36 that enable the forks 12 to pass therethrough to enable lifting and transporting of the intermediate container 10.
The collection arm 40 is coupled with the intermediate container 10. The collection arm 40 is mounted with a portion of the collection arm 40 positioned inside of the container 10. The collection arm 40 includes a housing 42, a slide member 44, a bracket 46, a frame 48 and a grabber assembly 50. The arm assembly housing 42 is secured to the inside of the rear wall 26. The housing 42 includes a cover 52 that surrounds the housing 42 prohibiting refuse from contacting the slide member 44. The housing 42 is secured with the inside of the rear wall 26. The cover 52 is secured with the housing 42 and rear wall and protects the slide arm 44 against the refuse. The housing 40 and cover 52 form a channel or pocket 56 for the slide arm 44. The slide arm 44 slides horizontally in the channel 56 provided by the housing and the cover 52. A cylinder 54 is coupled with the housing 40 or the rear wall 26 and also with the slide arm 44. The cylinder 54 enables the slide arm 44 to extend from the intermediate container 10 as illustrated in
A slot 60 is formed in the rear wall of the intermediate container 10. The slot 60 enables the bracket 46 attached to the slide arm 44 to extend outside of the container 10. The bracket 46 includes a clevis 62 that receives a pin 63 and the portion of the frame 48. A hydraulic cylinder 64 is coupled between the bracket 46 and the clevis 62 to rotate the frame 48 with respect to the pivot pin 63.
The frame 48 has an L shape. One leg 66 is attached to the bracket clevis 62. The other leg 68 is mounted with the grabber assembly 50.
Protective members 70 project from the outside of the rear wall 26. They are positioned between the rear wall 26 and the refuse vehicle 14. The members 70 protect the arm assembly 40 from damage.
By having the slide arm 44 positioned within the container 10, this enables a more streamline arm assembly 40 reducing the width of the arm assembly 40 in the portion that extends from the rear wall 26 of the intermediate container 10.
The foregoing description of the embodiments has been provided for purposes of illustration and description. It is not intended to be exhaustive or to limit the disclosure. Individual elements or features of a particular embodiment are generally not limited to that particular embodiment, but, where applicable, are interchangeable and can be used in a selected embodiment, even if not specifically shown or described. The same may also be varied in many ways. Such variations are not to be regarded as a departure from the disclosure, and all such modifications are intended to be included within the scope of the disclosure.
