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.
Abstract:
A device is disclosed that utilizes a fluid (normally air) to effect nested alignment of articles such as cans to be used to package beverages and the like. A conveying section provides articles in a mass flow to an aligning section having spaced guides therein forming guideways through which articles are fluid driven downstream toward a staging section. The guides have a first portion extending parallel to the direction of intended article flow through the device and all guides except center guides have a second portion that extends downstream from the first portion at an angle with respect to the first portion to effect alignment of the articles in nested relationship at the staging section. Different groups of guides of the first portion extend upstream different distances to facilitate passage of articles into the guideways, and an embodiment is disclosed that is particularly useful in aligning undecorated cans. A plurality of readily removable top cover units preclude upward movement of the articles, and nested and aligned articles discharged from the staging area are provided to a palletizer or like apparatus.
Abstract:
A device and method are disclosed for moving articles, such as cans, by groups, or tiers, from a pallet to an adjoining surface, such as a belt conveyor. A pair of sweep arms of a sweep unit move about a closed loop path to alternately engage the trailing portion of groups of articles when at a pallet sweep area to urge each group from the pallet. A pivotable retainer arm of a retainer unit, mounted on a reciprocating carriage moved by a driver following a closed loop path, engages the leading portion of the group of articles to be then moved from the pallet and thereafter leads the group from the pallet. The sweep and retainer arms are simultaneously moved by cycles whereby the sweep arms are alternately moved from a home position to engage the trailing portion of a group of articles and urge the engaged group from the pallet and the retainer arm is moved from a home position in a direction opposite to movement of the sweep arm to engage the leading portion of the group of articles with the retaining arm being thereafter moved in unison with the sweep arm to lead the group from the pallet.
Abstract:
A conveying device with a diverter having a curved path for conveying lightweight unstable articles, such as plastic bottles having a neck portion with a neck ring thereon. The unstable articles are conveyed along a first path to different ones of plural second paths through a third path at the diverter with the third path having first and second ends alignable with the first path and different ones of the plural second paths and a middle portion maintained in a curved configuration that is varied during aligning movement of the second end. A controller controls the aligning movement of the second end, preferably along a straight path, and the unstable articles are supported by engaging members in actuating guides to urge the unstable articles along the article paths.
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. The unstable articles are urged along the article conveying path by a second actuator, such as an air conveyor and/or a movable belt.
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. The applied force is tapered near the ends of the conveyor, preferably using shorting bars, and a bar placement pattern for applied force adjustment is utilized to facilitate article movement onto and/or from the conveyor.
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. The fluid, such as an air-liquid mixture that includes liquid not then gravity separated in the chamber from the air, is discharged from the chamber to a pressure source that also provides positive pressure through a conduit to a perforated top plate positioned at the predetermined path.
Abstract:
A conveying system is disclosed for conveying unstable articles having a neck ring. Unstable articles, such as plastic bottles having a neck ring, or flange, are conveyed in single file along plural paths each of which is established by dual guides vertically spaced from one another a distance just sufficient to receive the neck rings of the articles therebetween, with the articles being urged in the downstream direction along each path by air acting solely on the top portion of the articles above the neck rings. A combiner unit controls single filing of articles conveyed along the plural paths to a discharge conveyor through use of star wheel actuators, the arms of a first group of which are moved in the downstream direction along the plural paths with the arms being configured to engage the neck rings of articles then on the plural paths and thereafter control movement of the articles in conjunction with a second group of star wheel actuators, the arms of which are also moved in the downstream direction along the plural paths.
Abstract:
Article diverting and storage system and method utilizing a thru-flow palletizer/depalletizer. Articles on an article conveyor are diverted from the article conveyor at a first location and moved along a first path toward a discharge end where a sweep unit of a palletizer/depalletizer urges and leads the diverted articles onto a pallet by groups for storage. When the stored articles are later needed, the articles are urged and led from the pallet by groups by the sweep unit and a retainer unit of the palletizer/depalletizer and moved along a second path separate from the first path to a second location of the article conveyor downstream from the first location where the articles are inserted onto the article conveyor. The system and method are particularly useful for storing cans diverted from a high speed can production and/or handling line, and for later supplying stored cans, when needed, to the line.
Abstract:
A device is disclosed that utilizes a fluid (normally air) to effect nested alignment of articles having a circular cross-section (such as cans used to package beverages and the like). A conveying section that includes a dead plate and a fluid conveyor provides articles in a mass flow to an aligning section having guides therein spaced a sufficient distance to form guideways through which articles are fluid driven in single file toward a discharge end having an adjacently positioned staging section that also includes a fluid conveyor. The guides, other than a center guide, have first and second portions that are angled with respect to one another, and fluid injected into the sections through apertures in a base plate providing section bottoms urges the articles into a plurality of adjacent rows of aligned articles at the staging section with the articles of each adjacent row offset from one another to effect nesting of the articles. Readily removable section top units preclude upward movement of the articles, and nested and aligned articles discharged from the staging area are provided to a palletizer or like apparatus.
