A manually controlled and operable self-propelled seed bed sterilization system and method is provided for preventing weeds from growth in seed beds. The system includes a wheel driven shuttle vehicle having a hot water reservoir, a hot water applicator manifold housing, a dual-function pump and a controllable valve. A self-contained mobile hot water supply vehicle accompanies the shuttle vehicle and has a water heater with hose connections to the reservoir of the shuttle vehicle to provide a continuous water flow path. The burner of the water heater is controlled to heat the water in the range of about 205-207 degrees F. but below the boiling point of water not to create steam. The shuttle vehicle is displaced over the seed bed at a constant drive speed by an electric motor driven by a gas generator. An operator person guides the shuttle vehicle over the seed bed.

Apparatus and process for stretch wrapping articles, especially heads of lettuce, wherein a roll () of film () is supported on a housing (), and the film is supplied from the roll around a dancer roller () and film feed roller () to a pair of film feed grippers () which grip a leading edge of the film and advance it past an opening (), whereupon a clamp () engages the leading edge of the film to hold it while the grippers release and return to their home position. Additional clamps () then engage the film to hold it in place over the opening. A head of lettuce (L) is placed on the film in centered relation to the opening, and a ram () engages the lettuce and pushes it against the film to stretch the film through and below the opening. Gathering bars () engage the film stretched between the opening and the head of lettuce to gather the film in a first direction, and a U-channel () and sealing and trimming mechanism () gather the film in a second direction to produce a narrow necked down section of gathered film, fuse and seal the necked down section to produce a wrapped head of lettuce, trim excess film from the lettuce, and release the wrapped head of lettuce to drop onto a take away conveyor. The film () is a polyethylene based multi-layer film with an outer polypropylene layer for added gloss, slip and clarity, has a 300% stretch capability, is FDA approved for direct food contact, has an anti-fog additive for moisture dissipation during temperature fluctuations, is thirteen microns thick, and has a width of sixteen inches.

Apparatus and method for stretch-wrapping articles

An automatic turret bagging machine utilizes a turret transport mechanism having four article receiving compartments to receive liquid pouches, herein milk pouches, oriented longitudinally therein. An indexing motor drives the turret transport mechanism between an article loading position, an article discharge position, an intermediate position and an article unloading position. A control plate is synchronized with the turret transport mechanism and provides a support for a follower bearing member secured to the trap door of each of the compartments whereby to retain and release articles loaded in the compartments. The control plate also has a formation which automatically recloses the trap doors of the compartment upon reaching a predetermined position and simultaneously repositions the follower bearing member with a lower surface of the control plate. In the event that an improper number of pouches are loaded in a compartment, that compartment will not unload and the discharge position and the bag opening and positioning mechanism will idle during one cycle step and the improper number of pouches will automatically be discharged at the article unloading position for recycling.

An automatic bagging machine is comprised of a discharge station for releasing one or more articles in an open top end of a plastic bag held thereunder. The machine is fed by a plurality of bags held side-by-side by a continuous top band portion. At the loading station, two clamping assemblies engage a respective top band portion at the top end of opposed side walls of the bag and a displacing mechanism moves the clamping assemblies on an angled path to a retracted position outwardly from one another on an angled path. Simultaneously a pivoting tension roll permits a predetermined length of the band portion and attached bag to be drawn towards the bag filling station to advance the plurality of bags whereby to permit the bag at the filling station to be opened by the two clamping assemblies. After the bag is filled it is displaced to a discharge station where the filled bag is disconnected from the continuous top band portions and released on a discharge conveyor. The bag discharge means simultaneously draws a next bag to be filled to the filling station. A turret having four compartments conveys the articles to the filling station and releases the articles into the open top end of the bag only if a proper number of articles is present in the compartment.

A wicket for a bagging machine is useful for placing a plurality of objects in a first bag (11) of a plurality of juxtaposed bags. Each bag has a front (17) and back (16) wall portion and an extended tab (13). The extended tab 13 has at least two wicket apertures (18) and the bottom of the bag 71 has at least one bottom wicket aperture (19). The bags are held in a wicket comprising upper wicket pins (12) and lower wicket pin (14). Lower wicket pin holds the bottom (71) of the bag. Lower wicket pin (14) aids in overcoming difficulties experienced with bags sticking to one another. The bag mouth is opened, e.g. with an air jet, and then clamped and pulled open. The machine is useful for packaging liquid-filled pouches, vegetables and the like in bags which are placed in a case or box.

Wicket for bagging machine

A bagging machine comprising a product discharge device for discharging one or more products in an open bag held at a bag loading position. The open bag is a forwardmost one of a plurality of collapsed bags supported in juxtaposition adjacent the bag loading position. The bags have a flap, contiguous with a rear wall of the bag, which extends above a mouth opening of the bag. The flap is supported by one or more wicket pins. An air jet nozzle is disposed above the mouth opening to open the forwardmost bag by separating the front wall of the bag from the rear wall. A bag gripping device is disposed on opposed sides of the forwardmost bag and has clamps to clamp an upper edge portion of the bag on opposed sides thereof when the mouth opening is opened by the air jet. The bag gripping element is secured to a pivotal linkage to cause the engaged clamps to move toward one another, inwardly of the bag, and downward to detach the bag from the one or more wicket pins while retaining the bag with one or more products discharged therein. Means is provided to disengage the gripping elements to release the bag with the products therein.
