摘要:
An air controlled conveying device is disclosed for conveying unstable articles (9), such as plastic bottles, having a neck portion (11) with a neck ring (12) thereon. The unstable articles are conveyed in single file in the downstream direction along a path (18) established by guides (20,21) receiving the neck portions of the unstable articles therebetween. A plurality of plenums (28a-j) receive controlled air from a separate plenum (24) to establish different plenum air pressures, and air from the plurality of plenums (28a-j) is directed toward the neck portions (11) of the unstable articles (9) then between the guides (20,21) to urge the unstable articles along the guides at flow rates dependent upon the different air pressures then established in the plurality of plenums.

An air conveyor moving light objects from one location to another may also act as an accumulator for storing objects transported thereon. The conveyor has an elongated primary plenum (4) and one or more elongated body members (12) disposed over and in communication with the primary plenum through openings in the bottom wall (22) of each body member. Each body member has a generally planar top deck (30) disposed thereover. Each body member defines a secondary plenum (32) between the top deck and the bottom wall of the body member. The top deck has a plurality of directional orifices (44, 45) formed therein. Blowers (40) in communication with the primary plenum supply air to the secondary plenum through the primary plenum. The air from the secondary plenum is delivered through the directional orifices in the top deck and creates a current, or cushion, of air on which the objects move. Manually adjustable dampers (52) are provided for restricting the size of the openings and regulating the air pressure between the primary plenum and the secondary plenums. The conveyor may also have guide rails (98) for controlling object movement.
摘要:
A device (9) is disclosed that utilizes a fluid (normally air) to effect nested alignment of articles (17) such as cans to be used to package beverages and the like. A conveying section (19) provides articles (17) in a mass flow to an aligning section (12) having spaced guides (41) therein forming guideways (42) through which articles (17) are fluid driven downstream toward a staging section (13). The guides (41) 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 in a manner 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.

A conveying device with a diverter is disclosed for conveying lightweight unstable articles (12), such as plastic bottles having a neck portion (14) with a neck ring (15). The articles (12) are conveyed along a first path (16) established by a first guide unit (17) to different ones of plural second paths (18) established plurality of second guide units (19) through a third path (20) established by a third guide unit (22) having a diverter (21) to align a first end (24) of the third path (20) with the first path (16) and to move the second end (26) of the third path (20) for alignment with the different ones of the plural second paths (18) with a deviation in the third path (20) between the ends thereof being established during aligning movement of the second end (26) of the third path (20) by flexing of a flexible bar (27) positioned adjacent to the third path (20).
摘要:
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 (13), moves the articles along a predetermined path (17) 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 (78), and a bar placement pattern for applied force adjustment is utilized to facilitate article movement onto and/or from the conveyor.
摘要:
Articles, such as glass or plastic bottles (10), are conveyed in single file to an accumulating area (14), with the containers at the accumulating area being formed into a pattern, preferably in nested relationship. A conveyor system (16) is provided to urge articles from the accumulating area (14) to, and partially through, a sweep area (18), and a movable retainer unit (20) having retractable plungers (46) is provided to control the movement of articles from the accumulating area (14) by groups to the sweep area (18) with the sweep area having a positioner unit (22) thereat that includes a plurality of movable sweep arms (60,62,64,66,68) adjacent ones of which are utilized to engage the first and last rows of each group of articles to capture each group therebetween and thereafter conduct each group of articles through the sweep area to a pallet loading area (24) where each group is successively deposited as a layer on a pallet.
摘要:
An apparatus (15) for transit of articles (37) between a transfer surface (25) and an adjacent separator sheet (33) is disclosed with the apparatus (15) having a selectively positionable and extendable bridge for providing a transitional surface between the transfer surface (25) and the sheet (33) and for overlapping a portion of the sheet (33) adjacent to the transfer surface (25) when in a first position, and for providing a clearance for placement and positioning of the sheet (33) when in a second position.
