20100146908 | Apparatus and method for compressing and bagging a loose material - An apparatus for compressing a loose material that includes a compression chamber. Movement of a first ram discharges the loose material in a compressed state through an outlet port in the compression chamber. A packaging receptacle is positioned proximate the outlet port to receive the compressed material. The packaging receptacle is then moved to a second position where the movement of a second ram ejects the compressed material from the inner volume of the packaging receptacle. The second ram may be alternatively extended into and retracted from the packaging receptacle during ejection of the compressed material. The refilling of the compression chamber for the next cycle may begin prior to the retraction of the second ram from the packaging receptacle. A packaging jacket may be positioned about the packaging receptacle such that the ejection of the compressed material injects the compressed material into the packaging jacket. | 06-17-2010 |
20120255834 | Bulk material leveling and volumetric measuring and feeding apparatus - A bulk material leveling and volumetric measuring and feeding apparatus includes a conveyor for transporting bulk material from a hopper to a leveling assembly. The leveling assembly includes a pair of augers located perpendicular to the conveyor and with the auger terminal ends at a desired height from the conveyor. Side walls are provided parallel to the conveyor direction of travel and extend up to the auger terminal ends. Each auger is positioned within a semicircular longitudinal channel of a trough. Bulk material being transported and which is located above the augers terminal ends is lifted by the augers and thrown back towards the hopper. Thus, bulk material being transported under and beyond the leveling assembly is maintained at a desired depth. By monitoring and/or controlling the conveyor speed and the depth of the transported bulk material, the volumetric feed rate and total volume of transported material can be determined and/or controlled. The height of the leveling assembly above the conveyor is selectively adjustable. A shutoff gate is provided downstream of the leveling assembly. | 10-11-2012 |
20130097965 | Apparatus for forming elongate plastic film into a tube around variable size articles - An apparatus for forming elongate plastic film into a tube around variable size articles includes a conveyor and a forming collar positioned over the conveyor. The forming collar includes left and right sections pivotally supported on a common carrier and moveable relative to the conveyor. The carrier is also moveable relative to the conveyor. The plastic film tube is formed by directing the central film area onto the conveyor, the left film side onto the inside surface of the left collar section and the right film side onto the inside surface of the right collar section. Movement of the forming collar left and right sections about their pivotal supports and/or movement of the carrier cause the forming collar sections to move between retracted and expanded positions for thereby forming a variable size plastic tube corresponding to the article size being received therein. | 04-25-2013 |
20130097966 | Apparatus for joining overlapped side edges of plastic film sheet formed into elongate tube - A joining apparatus and methods wherein, after plastic film is formed into a variable size tube for receiving therein and enveloping corresponding variable size large articles such as bales of cotton, trash, cloth, etc., the joining apparatus joins an overlap region of the plastic film tube for effectively sealing and creating the plastic film tube. The joining apparatus includes an inner shoe located inside the formed tube. The overlap region slides over the inside shoe as the tube is formed. An outside shoe is moveable between an idle position away from and an operative position adjacent to the inside shoe. When in its operative position, the overlap region is sandwiched between the outside and inside shoes and heated air is provided under pressure through a groove on the outside shoe and onto the overlap region for effectively heating and joining the overlapped plastic sheets. | 04-25-2013 |
20130097976 | Method and apparatus for unfolding folded plastic film for use in forming a packaging tube - An apparatus for unfolding folded plastic film having a first side joined to a second side along a longitudinal folded edge for use in forming a packaging tube. The folded film travels through a slot and the folded sides are separated at their respective outer longitudinal edges. The longitudinal left side is conveyed toward and over a guide plate left side edge and then over a left form tube section. The longitudinal right side is conveyed toward and over a guide plate right side edge and then over a right form tube section. The longitudinal middle section including the longitudinal folded edge and part of both the first and second sides adjacent the longitudinal folded edge is conveyed toward and over guide plate angular edges and then onto a carrying surface. | 04-25-2013 |
20140360135 | Bags, Method of Making Bags and Method of Use Thereof for Enveloping Rectangular Bales - A continuous web of closed, preformed end-to-end bags for enclosing bales of material are made by forming an elongate sheet into a helix tube, flattening the tube into first and second elongate bag walls and securing the bag walls at closure seams located along the flattened helix tube. The helix tube is formed by nesting the elongate sheet side edges into U-shapes and sewing. The bag walls are secured to one another by nesting them into U-shapes and sewing. Bales are enveloped by severing the web and thereby providing a bag with an open end, separating the bag walls, inserting a bale therein, closing the bag and severing from the remaining web. Each bag is located along the web with a pair of sensors which provide a locating signal responsive to the bag closure seams. | 12-11-2014 |
20140360138 | APPARATUS AND METHOD FOR CLOSING AND SEALING BAGS IN BALE ENVELOPING APPARATUS - An apparatus for closing and sealing a preformed polypropylene bag after a bale has been inserted therein as the bale and bag traverse along a longitudinal line of travel. Left and right rotatable side flaps fold the left and right bag closure flaps onto the bale. A bottom rotatable fold plate partially folds the bag bottom closure flap and a top fold bar is extended and folds the top bag closure flap onto the bale. The bottom fold plate then folds the bag bottom closure flap onto the bale. The top and bottom bag closure flaps are sandwiched between the rotatable side flaps and the bottom fold plate and over a slack bar therebetween forming a slack portion. A heating assembly directs heat to the slack portion melting the polypropylene and a press plate is extended to the slack melted portion thereby fusing the bag closure flaps together. | 12-11-2014 |
20140360139 | APPARATUS AND METHOD FOR OPENING BAGS IN BALE ENVELOPING APPARATUS - An apparatus for separating the bag walls of preformed bags having an open end and a closed end for use in an apparatus for enveloping bales of material. The bag walls are initially adjacent one another. Vacuum and grip pin assemblies are provided on jaws which are movable between retracted and closed positions. The jaws are closed onto the bag walls and a vacuum is applied to vacuum inlet openings drawing the bag walls thereto. Preferably, the jaws are partially separated and then a grip pin is extended adjacent the vacuum inlet openings thereby piercing and securely gripping the walls. The jaws are then retracted thereby fully separating the bag walls and opening the bag. Preferably, the vacuum inlet openings are saddle shaped having a rim defining aligned raised sides and aligned lowered sides therebetween, and the grip pin extends along the aligned raised sides. | 12-11-2014 |
20140360140 | APPARATUS AND METHOD FOR PLACING BAGS OVER INSERTION TUBE IN BALE ENVELOPING APPARATUS - An apparatus for placing preformed bags having an open end and a closed end over an insertion tube for inserting a bale therethrough and into the bag. A plurality of fingers are inserted into the bag open end and are extended for engaging the bag. The fingers and bag opening are traversed to the tube thereby inserting the tube end into the bag opening. The fingers are retracted and removed from the bag. The insertion tube is expanded thereby engaging the interior surface of the bag. Roller drive wheels are placed on the bag over the insertion tube and are rotatably driven and are traversed along the insertion tube for collecting the bag thereon. The roller drive wheels and the plurality of fingers are carried on a common assembly movable along the insertion tube. | 12-11-2014 |
