Abstract:
A conveyor apparatus is provided which includes a pair of conveyor belts constructed from a resilient material and arranged to securely grip and release the neck ring of bottles to be conveyed. Each one of the conveyor belts is formed with a groove having coacting opposed sides. The opposed sides part to open the groove to facilitate and expedite receiving the bottle neck ring in the grooves of the conveyor belts. The opposed sides of the groove then coact to close the groove and securely grip the neck ring therebetween to transport the bottle. At the discharge area of the conveyor line, the opposed sides once again flex away from the groove to facilitate and expedite the discharge of the bottle from the groove of the conveyor belts. Also provided is an adjustable block to support the conveyor belts, which block is constructed with at least one (1) port arranged to direct the flow of gas along the conveyor belt and into the conveying path. The introduction of the air stream into the conveying path permits the bottles to levitate or float above the belts without the belts having to be idled.
Abstract:
An air conveyor which includes guides for stabilizing articles during conveyance and a plenum with apertures for providing pressurized air is provided. In the preferred embodiment, the air conveyor also includes opposed spacers defining passages having a closed end and an open end. The passages are in fluid communication with the apertures of the plenum for directing streams of pressurized air through the open ends at the articles in a downstream direction to propel the articles. In another embodiment, channels defined in support structure for the guides form part of passageways for directing streams of pressurized air at an inclined and downstream angle to propel the articles. The guides are removable to allow the conveyor to be adapted to different sized and shaped articles. The air conveyor may also include an additional plenum and additional opposed spacers associated with the plenum for propelling the articles downstream.

Abstract:
A pneumatic conveyor apparatus for conveying articles, such as empty aluminum cans and plastic bottles, includes first and second air ducts for supplying pneumatic pressure to move the articles along a predetermined path. The first and second air ducts each have a plurality of vents which direct the flow of air on the articles to move the articles along the path and to exert a lifting force on the articles as the articles are moved downstream. Guide plates extend along both sides of the predetermined path for supporting the articles in a generally upright position as the articles are moved along the path. The first and second air ducts each have a plurality of deflectors mounted therewith, which extend from the respective first and second air ducts into the predetermined path. The deflectors direct air flow upwardly and inwardly, thereby enhancing the pneumatic force urging the articles downstream. The direction of the conveyor path is changed by miter cutting the first and second air ducts at selected locations and joining the miter cut sections in end-to-end abutting relationship. The guide plates are each defined by alternating straight and curved guide plate sections, to effect the desired change in direction.
Abstract:
An air conveyor for plastic bottles conveys the bottles at generally constant speed. The bottles are of the type having annular rims around their necks and shoulders below the rims. The air conveyor includes a pair of spaced flanges and a plurality of nozzles for each flange. The flanges provide opposed inner edges which define a central slot extending elongately in the forward to rearward direction. Each flange supports a plurality of nozzles at spaced intervals in the forward to rearward direction for substantially the length of the slot. An air blower supplies pressurized air to the nozzles. Each nozzle discharges air in a stream along a diagonal direction that generally slopes downwardly, inwardly, and forwardly. In use, the flanges provide the neck rims with slidable support as the bottles are blown forwardly through the slot by the force of the air streams against the shoulders. Constant speed is gained through the direction of the air streams against bottle shoulders.
Abstract:
The invention relates to an apparatus for conveying containers having an annular neck flange, in particular, a guided suspended conveyor chain having support elements each defining a "U" shaped recess having a pair of substantially parallel sides which are oriented transverse to the path of travel of the conveyor chain so that the "U" shaped recess is accessible from the side of the path of travel. The "U" shaped recess is sized to receive the container neck, is sized smaller than the annular neck projection of the container and is further sized so that the substantially parallel sides of the "U" shaped recess extend beyond the container neck of any container received therein so that the container may hang suspended in the "U" shaped recess. In addition, the conveyor chain is designed to be driven by a suitable drive stand to provide mechanical energy to associated container processing apparatus having sprockets adapted to engage the conveyor chain.
Abstract:
An intersection is provided for bottle conveyor lines having individual neck guide pairs. The intersection comprises a transfer plate and a pair of changing plates. The transfer plate includes a substantially Y-shaped opening extending to the edges thereof and comprising two arm members and a leg member defining a central plate portion and side plate portions. Each arm member when combined with the leg member forms a substantially continuously curving bottle path. The changing plates are movable, preferably vertically, between first positions in planar alignment with the transfer plate and second positions clear of bottles moving along the paths. The changing plates include an edge spanning one bottle path from opposite sides of the leg portion of the Y-shaped opening to the point of intersection of the converging edges of the central plate to complete the bottle supporting guides along the other bottle path.
