Abstract
Abstract A method of loading bales of refuse from a horizontally acting baling press on to a transport vehicle without the use of a separate loading machine such as a fork-lift truck comprises aligning the transport vehicle with a discharge from the press; moving each bale as it is discharged from the press on to a transverse table; moving some of the bales laterally so that the bales are formed into two or more rows side by side aligned with the transport vehicle and moving the two rows of bales progressively forward as successive bales are discharged from the press so that the rows are moved from the transverse table on to the vehicle and the rows are built up on the vehicle until the vehicle is fully loaded. The apparatus for carrying out this method comprises a discharge table arranged at the outlet of the press, a transverse table aligned with the discharge table and on the side of the discharge table remote from the press, the transverse table having a drive by which it is horizontally displaceable across the direction of discharge of the bales from the press and a longitudinally movable hauling tongs which is arranged to move single bales forward from the discharge table on to the transverse table and then to move the two or more rows of bales which are assembled from the transverse table forward on to the transport vehicle.

Claim 1
Independent Claim
309 words
A method of loading on to a transport vehicle bales of waste material which are ejected successively from a horizontally acting baling press, said method comprising the steps of: (a) positioning the transport vehicle, which has a load deck, with the vertical longitudinal central plane of said deck substantially in alignment with the vertical central plane of a discharge opening of said baling press; ejecting a row of bales in succession from said discharge opening; causing a first bale of said row of bales to reach a preliminary position; conveying said first bale from said row individually from said preliminary position in the direction in which said bales are ejected from said discharge opening; (b) moving said first bale further in said direction to a first predetermined limiting position; (c) moving said first bale perpendicularly to said direction horizontally through a distance exceeding the width of said bale; (d) causing the succeeding bale in said row to reach said preliminary position; separating said succeeding bale from said row when said bale has reached a preliminary position, said succeeding bale being moved in said direction to said first predetermined position; (e) moving said first bale and said succeeding bale together back perpendicularly to said direction into a position symmetrical with respect to said vertical longitudinal central plane whereby a gap previously existing between adjacent sides of said first bale and said succeeding bale is eliminated; (f) moving said first bale and said succeeding bale forwards together in said direction on to said transport vehicle, said first bale and said succeeding bale both moving through a distance exceeding the length of one of said bales in said movement on to said vehicle; and (g) repeating the foregoing sequence of steps with further pairs of bales, each pair comprising a first bale and a succeeding bale, until said vehicle is fully loaded.
Claim 2
Independent Claim
309 words
A method of loading on to a transport vehicle bales of waste material which are ejected successively from a horizontally acting baling press, said method comprising the steps of: (a) positioning the transport vehicle, which has a load deck, with the vertical longitudinal central plane of said deck substantially in alignment with the vertical central plane of a discharge opening of said baling press; ejecting a row of bales in succession from said discharge opening; causing a first bale of said row of bales to reach a preliminary position; conveying said first bale from said row individually from said preliminary position in the direction in which said bales are ejected from said discharge opening; (b) moving said first bale further in said direction to a first predetermined limiting position; (c) moving said first bale perpendicularly to said direction horizontally through a distance exceeding the width of said bale; (d) causing the succeeding bale in said row to reach said preliminary position; separating said succeeding bale from said row when said bale has reached a preliminary position, said succeeding bale being moved in said direction to said first predetermined position; (e) moving said first bale and said succeeding bale together back perpendicularly to said direction into a position symmetrical with respect to said vertical longitudinal central plane whereby a gap previously existing between adjacent sides of said first bale and said succeeding bale is eliminated; (f) moving said first bale and said succeeding bale forwards together in said direction on to said transport vehicle, said first bale and said succeeding bale both moving through a distance exceeding the length of one of said bales in said movement on to said vehicle; and (g) repeating the foregoing sequence of steps with further pairs of bales, each pair comprising a first bale and a succeeding bale, until said vehicle is fully loaded.
Claim 3
Dependent Claim
80 words
A method as claimed in claim 1, further comprising the step of determining the length of each bale during steps (a) and (b) comprising utilizing a gripping and pushing device for moving the bales, determining the movement of the gripping and pushing device in the length direction of the bales in positioning the pushing and gripping device relative to the bale being moved in steps (a) and (b), and collecting and summing the movements of the gripping and pushing device.
Claim 4
Dependent Claim
155 words
A method as claimed in claim 1, further comprising the step of determining the length of each bale of each row of bales formed on said vehicle during said movement of said bale in steps (a) and (b), comprising utilizing a gripping and pushing device for moving the bales, determining the movement of the gripping and pushing device in the length direction of the bales and positioning the gripping and pushing member relative to the bale being moved in steps (a) and (b), collecting and summing the movements of the gripping and pushing device, and the step of effecting the termination of said loading operation in dependence upon a comparison between the length of the load deck of said vehicle and the sum of the lengths of the bales in that one of said rows of bales which is longer than the other and shorter than the length of the load deck of said vehicle.
Claim 5
Dependent Claim
68 words
A method as claimed in claim 1, further comprising the step of visually checking said bales for damage during step (a) and the step of separating a damaged bale, after the completion of step (b), from said row of bales ejected from said discharge opening by moving said damaged bale in a direction opposite to the direction of movement of said bales which takes place in step (c).
Claim 6
Dependent Claim
275 words
A method as claimed in claim 1 further including the steps of utilizing a gripping and pushing device for effecting the movement of the bales, placing the forward end of a bale to be moved in contact with the rearward face of the device prior to moving the bale from the preliminary position, moving the device rearwardly into a gripping position with the bale at a location intermediate the forward and rearward ends of the bale, determining this first length of movement of the device into the gripping position from the position where the front end of the bale contacts the rearward face of the device and collecting this determined first length of movement, after moving the bale into the first predetermined limiting position, releasing the device from gripping engagement with the bale and moving the device rearwardly relative to the bale in the first predetermined limiting position to a location spaced rearwardly of the rearward end of the bale in the first predetermined limiting position and determining this second length of movement of the device from the gripping position to the rearward face of the device and collecting this determined second length of movement, moving the device forwardly so that the forward face of the device just contacts the rearward end of the bale and determining this third length of movement of the device into contact with the rearward end of the bale, adding these first and second lengths and from the sum thereof subtracting the third length and the length between the forward and rearward faces of the device for determining the lengths of the bale moved into the first predetermined limiting position.
Claim 7
Dependent Claim
