An apparatus (20) is provided for transferring articles (40--40) from a pickup position to a pickoff position and then to a dropoff position. The apparatus includes a pair of pickup arms (60--60) which are spaced apart to engage lugs (42--42) oppositely extending from an article to be transferred. As the transfer arms are caused to be moved rotatably, the article is transferred to the pickoff position whereat the lugs are adjacent to stepped end portions (88--88) of a pair of pickoff arms (80--80). Further movement of the transfer arms causes the article to engage surfaces (92--92) of the stepped free ends of the pickoff arms and to be supported by engagement of the lugs with surfaces (94--94) of the stepped end portions of the pickoff arms. Afterwards, the pickoff arms are turned to allow the article to descend until, at a predetermined position, the lugs of the article become engaged with a conveyor (100) and become disengaged from the pickoff arms. Successive ones of the articles are supported by engagement of the lugs with the conveyor such that main body portions of the articles are submerged in a treating bath beneath the conveyor.
An arrangement for conveying an anode plate from one location to another, whereby said arrangement comprises gripping elements attached to a conveyor for gripping a plate-like piece. Elements are attached to the gripping element connection for the correction, at least partial, of any possible positional error of the anode to be transferred.
The invention relates to a conveyor device for a modularly arranged machine line for manufacturing containers, in particular tubs. A system of clamps which brings the tubs step-by-step to each work station is operated by means of a crank drive.
An apparatus for conveying and rotating book packs (11), pamphlet bundles and the like upon deposition onto a conveyor belt (7) for stacking the packs (11) onto a pallet or a stacking plane, comprising a device (A) for grasping and rotating the pack (11) and an articulated device with chain (6) for advancing (B) the device (A).
An apparatus for chemically treating the surfaces of printed circuit board work pieces (PCBWP's) includes a tank for holding a bath of the chemical treatment liquid. A receiving device is provided for receiving the PCBWP's from a conventional transport conveyor in a horizontal orientation, and immersing the PCBWP's into the bath in a substantially vertical orientation. A conveyor device in the tank is configured to hold the PCBWP's in the vertical orientation and to move them face-on through the liquid bath while a substantially uniform transverse flow of fresh liquid is provided between the work pieces. Another conveyor device receives the PCBWP's and elevates them out of the bath in the vertical orientation, subsequently returning them to a horizontal orientation for delivery to a conventional transport conveyor.
