The positioning device includes a movable unit having a slider relatively movable with respect to a mounting unit by a pneumatic unit with the slider having a pawl and a connector connecting the article engagable unit for movement with the slider. A mechanical unit includes a shaped wheel and a ratchet wheel rotatable with the shaped wheel and engagable with the pawl on the slider upon movement of the slider in one direction to rotate the ratchet wheel and shaped wheel to successively move each of a plurality of stops spaced about the periphery of the shaped wheel to a stop area for engagement thereat with the slider when moved in a second direction to thereby establish a plurality of selectable set positions for the article engagable unit along the engaging path.

Abstract: A selective conveying device is disclosed for conveying unstable articles, such as plastic bottles, having a neck portion with a neck ring thereon. Neck ring supported unstable articles are conveyed in single file along an article conveying path established by first and second guide units with the guide units having spaced connectors with neck ring engagable elements thereon spaced different distances from one another to receive the neck portions of unstable articles having different size neck portions. A first actuator, such as a pneumatic or mechanical actuator, causes relative movement between the guide units so that unstable articles are conveyed along the article conveying path on the neck ring engagable portions of the first guide unit when in a first operating position or are conveyed along the article conveying path on the neck ring engagable portions of the second guide unit when in a second operating position.

Abstract: Palletizers and methods of palletizing are disclosed. The palletizers are adapted to receive and arrange units of material and to concurrently fabricate first and second layers therefrom; or to place them in layers at either of first and second delivery support areas; or both. A plurality of layer forming stations can be vertically spaced, horizontally spaced, or both. Plural load forming stations can be horizontally spaced, vertically spaced, or both. Pallets can be sequenced into the load forming stations when empty or partially empty; and can be sequenced out of the load forming stations when empty, partially empty, or full.

Abstract: A single-to-multiple line conveying system for conveying unstable articles, such as plastic bottles, having a neck ring. The unstable articles are neck ring supported and are conveyed in single file along a first path established by a first guide unit to second paths established by a plurality of second guide units through a third path established by a third guide unit having a displaceable section to align the third path with successive ones of the second paths by an electric motor actuated in response to an article counter. The unstable articles are air conveyed along the first and second paths with continuous movement of the unstable articles along the third path being effected by a continuously rotating star wheel that spaces the unstable articles and urges the unstable articles toward the displaceable section that includes a mechanical unit, having a continuously moving chain with article engaging finger units thereon, and an air unit for urging the unstable articles from the third path.

Abstract: Apparatus and method are disclosed for conveying different types of force responsive articles, such as steel and aluminum cans, and particularly for efficiently conveying different force responsive articles between first and second positions, including positions at different elevations. A conveyor, such as a chain, moves the articles along a predetermined path between the first and second positions with the articles maintained in engagement during movement along the predetermined path and with the conveyor using different applied forces for different ones of the types of articles to be conveyed, such as a magnetic force for conveying steel cans and a negative pressure (vacuum) force for conveying aluminum cans. A support face for the conveyor has magnets mounted thereat to establish the magnetic force and apertures communicating with an adjacent plenum to establish the negative pressure force.

Abstract: This invention pertains to load forming systems, especially those designed to place cased product on e.g. a pallet. The invention contemplates receiving cases at a high rate of input, and fragmenting the input, sending it to parallel processing elements of the load forming system. A layer creating subsystem has parallel processing elements, and preferably has sufficient designed throughput capacity to continue processing cases at the overall rated capacity of the case loading system when any one of the parallel processing elements in the layer creating subsystem fails. The case loading subsystem also can incorporate parallel layer transfer elements and load forming elements.

Abstract: Article conveyor apparatus and method are disclosed having fluid containment, and particularly for conveying of articles such as cans having an oily liquid thereon when transported from a processing or forming station. The articles are mass transported along a predetermined path that is closed to the atmosphere except for infeed and discharge of articles, with the articles being transported by engagement with a moving belt having openings therein. The inlet of a chamber, otherwise closed to the atmosphere and having negative fluid pressure maintained therein during normal operation, is positioned adjacent to the belt so that the negative pressure maintains articles in contact with the belt during transport along the predetermined path regardless of path orientation and also draws fluid from the transported articles and belt into the chamber through the openings in the belt and the chamber inlet.

Abstract: This invention pertains to removing a row or layer of material from a supporting surface, with the row or layer advancing on a removal conveyor in a line abreast, and converting the row or layer into a line, advancing single file. Apparatus and methods are disclosed. Each unit of material is moved in turn, longitudinally out of its line abreast, and into sole occupation of a discrete length of the converting conveyor assembly. The units so moved longitudinally are moved, as necessary, transversely across the accelerating conveyor and into an alignment zone, and are then assembled into a line advancing single file.

Abstract: A height adjustable conveyor system conveys articles between different heights as needed. The conveyor system includes guides that support the neck rings of articles to be conveyed, and the guides are mounted on an air conveyor having multiple sections so that the guides are caused to be flexed by different movements of the air conveyor sections. The air conveyor has pivotably coupled first, second, and third sections with the first section being vertically adjustable with respect to the third section and the second section being between and tiltable with respect to the first and third sections to thereby flex the guides as necessary to readily effect article height variations as needed between the input and the output of the system. Relative movement between the three sections of the air conveyor is effected by a lever pivotably connected with a fixed support and the first section of the air conveyor with the lever being actuated by a crank.
