Abstract: Systems and methods for using a continuous, thermoplastic tubing as a casing in a wellbore are provided. A continuous, thermoplastic tubing can be a high density polyethylene (HDPE) material that is stored in a coiled manner on a spindle. A screen can be attached to an end of the casing, and a tremie line can be selectively connected to the screen to inject gravel and cement downhole to pack the screen in place and grout the casing in place in the wellbore. The use of a continuous, thermoplastic tubing removes joints from the casing to improve performance, and such tubing is more readily available and cheaper than alternatives among other benefits described herein.

Abstract: An loading apparatus (100) for use in a packaging machine includes a grouping conveyor (300) for conveying groups of articles (16) in a flow direction (10). The grouping conveyor (300) includes a plurality of conveyor plates (320) and grouping lugs (310) that are slidably attached to one of the plurality of conveyor plates (320) so as to be individually moveable in a transverse direction (90) to selectively extend to span the space between the grouping conveyor and a carton conveyor as needed to facilitate loading groups of the articles into cartons and to selectively retract to avoid impeding operation of the packaging machine. The grouping conveyor (300) also includes a multi-position locking mechanism (82) that releasably locks the grouping lug (310) in two transverse positions. A system of proximity sensors (530, 540) monitors the grouping conveyor (300) to ensure that the grouping lugs (310) are properly transversely positioned.

Abstract: A packaging machine having a folding apparatus for closing an end of an end loaded carton that includes leading and trailing side end flaps. The packaging machine includes a carton conveyor for transporting a carton in a flow direction along a carton path. The folding apparatus includes a lug assembly that has at least one folding lug that travels along an endless lug path. The folding lug travels in the flow direction and in parallel to the carton path along at least a portion of the lug path such that the folding lug can operate in concert with separation guide and a combination guide to fold the leading and trailing side end flaps in the desired sequence.

Abstract: A packaging machine (10) includes a lane assembly (12) that includes one or more lanes (L) which guide cylindrical articles (B), such as cans or bottles, across a series of substantially parallel conveyors. The lane assembly (12) includes an adjustable guide bar (34) which defines an adjustable portion (V) of the lane (L) that can be adjusted to adapt to the diameter of articles (B). The lane assembly (12) also includes lane extensions (70) that can be adjusted to control the position of rows or articles (B) as the articles (B) exit the lanes (L) onto a conveyor (20).

Abstract: An infeed station for conveying and positioning a stack of carton blanks for sequential removal by a carton feeder, for automatically adjusting the rate of advancement of the carton blanks to compensate for excessive tilting and gaps between the carton blanks, and for providing alerts to signal the need for operator intervention or automatic shutdown. The infeed station includes a hopper and a magazine that receives carton blanks from the hopper. The magazine includes a sensing mechanism including a control sensor and a warning sensor mounted in proximity to the carton blanks in the infeed station, and a processor that, according to a condition signaled by the sensing mechanism, controls the rate at which advancing belts advance a queue of carton blanks toward the magazine.

Abstract: A packaging apparatus (10) includes lanes (L) in which articles (C) are conveyed and grouped. Each lane (L) is defined by lane dividers (16a, 16b, 18, 20) and includes an upstream portion (12) and a downstream portion (14). The upstream portion (16) is defined by lane dividers (16a, 16b) that are substantially parallel to a first axis (X). The downstream portion (14) is defined by lane dividers (18, 20) that are substantially parallel to a second axis (Y), which is at an angle (A) with respect to the first axis (X). The width (W2) of the downstream portion (14) of each lane (L) is adjustable as an adjustable one of the lane dividers (20) that define the downstream portion (14) translates parallel to the first axis (X).

Abstract: A plunger assembly (30) is disposed on the access side of a conveyor (20). The conveyor (20) has a conveying surface upon which it transports articles by moving the conveying surface in a direction of flow (F). The plunger assembly (30) is mounted overhead vertically with respect to the conveying surface of the conveyor (20) such that sufficient clearance below the plunger assembly (30) is maintained to provide an access space through which the conveyor (20) and mechanisms and elements thereof can be accessed. Further, the plunger assembly (30) may be mounted both above and at least partially offset horizontally from the conveyor surface of the conveyor (20), such that no operative portion of the plunger assembly (30) breaks the plane (C) of the conveyor surface.

Abstract: A stabilized and guided conveyor belt (202) includes multiple transport chains (108) and interchangeable conveyor plates (100) that form the surface of the conveyor belt (202). The conveyor plates (100) can be easily attached independently of one another in a side by side fashion onto the transport chains (108) and are readily detachable from the transport chains (108) to facilitate replacement or rearrangement. Certain of the plates (100) function selectively as a platform on which to mount accessories such as lug members (136) and include means for receiving (134) accessories and for locking (138) accessories into place. The conveyor belt (202) is guided and supported by a smooth rail (420). Both the plate (100) and the rail (420) include interacting stabilizing features (130, 132, 424a, 424b) that cooperate to prevent buckling and rippling of the transport chain (108).
