US Patent:

49695525, Nov 13, 1990

Filed:

May 25, 1989

Appl. No.:

7/356864

Inventors:

Robert C. Kennicutt - Port Crane NY
Michael J. Oswald - Kirkwood NY

Assignee:

Universal Instruments Corporation - Binghamton NY

International Classification:

B65G 4724

US Classification:

198399

Abstract:

The device flips substrates or passes them through without flipping, selectively, and the substrate can enter either end and exit either end of the device, as desired depending on how it is assembled. The spacing between channels which restrain opposite edges of the substrate is adjustable so as to accommodate different widths. The channels are separate from, but cooperable with, feed wheels which extend into the channels and engage the board when the channels are not moved out of alignment with the feed plane, e. g. , when the flipping action is not taking place. During flipping, one end of each channel is raised above the feed plane, while the other end is moved substantially parallel to the feed plane so as to eliminate interference with an undercarriage or anything else below the feed plane of the device.

Abstract:

An adjustable conveyor for conveying a printed circuit board includes a frame, a first track including a first conveyor belt, a second track including a second conveyor belt, wherein the first track and the second track are mounted on the frame so that the first track and the second track are parallel to each other. Each of the first track and the second track includes a first element and a second element that are slidably connected to each other so that a space between the first element and the second element is adjustable so as to change a length of the respective track. Each of the first elements includes a plurality of slide blocks. The slide blocks are slidably mounted on the first elements in an overlapping manner so that an amount of overlap between the slide blocks is adjustable as the space between the first element and the second element is adjusted. The conveyor also includes a device for simultaneously driving the first and second conveyor belts.
