  • Patent number: 6824131
    Abstract: A sheet feeder separates a stack of sheet materials one by one for securely feeding individual sheet materials without multiple sheet feeding or failure in feeding a sheet material. The leading edge of a sheet material stacked on a bottom board of a cassette is brought into contact with a sheet feed roller. Near the location at which the leading edge of the sheet material comes in contact with the sheet feed roller, a tilt member is pressed onto the sheet feed roller by the action of a compression spring. A contact area of the tilt member with the sheet feed roller is reduced to prevent the sheet feed roller from rotating together with the sheet material. The topmost sheet material is fed by the rotation of the sheet feed roller in the counter-clockwise direction and supplied beyond the tilt member by friction with the sheet feed roller, whereas the next sheet material is blocked by the tilt member due to less friction between the sheet materials, thereby preventing multiple sheet feeding.

  • Patent number: 6822181
    Abstract: The present invention provides a device and method for selectively removing an article from a stream or line of similar articles travelling in a pathway on a transport system such as a conveyor. The invention utilizes a synchronous electric motor which, in response to a signal to reject a specific article in the stream, rotates an article-contacting member or paddle into the path of the stream of articles travelling along the pathway whereby it contacts and smoothly removes that article from the stream. The use of a synchronous motor to effect the rotation of the paddle is very important to the present invention.

  • Patent number: 6817611
    Abstract: A nip mechanism for a substrate transfer system includes: a first nip roller; a second nip roller located substantially vertically above the first nip roller; and a drive motor for driving the first nip roller and the second nip roller to feed a substrate between the first nip roller and the second nip roller when the drive motor is driven in a first direction. The second nip roller creates and maintains a nip with the first nip roller due to a force of gravity without using a spring or other mechanical device while the drive motor is driven in the first direction. The drive motor engages a one-way clutch for engaging a roller separation mechanism to raise and separate the second nip roller from the first nip roller when the drive motor is driven in a second direction. The first and second nip rollers maintain substantial vertical alignment with one another when the drive motor is driven in either direction.

  • Patent number: 6814211
    Abstract: The present invention pertains to a slide for a gravity-fed sorting machine. An optimum gravity slide configuration comprises one or more channels, with or without dividing ribs, and a product guide. The product guide has support tabs integral to or otherwise extending from its perimeter. Those tabs allow the product guide to be supported along it perimeter by brackets while retaining certain degrees of freedom regarding its ability to move. Specifically, the tabs rest in notches in the underlying support brackets that allow the product guide to be lifted up, thus permitting a potential obstruction to pass. Additionally, the brackets themselves are adjustably mounted to the sides of the slide. That allows the product guide's height above the channel bottom or dividing ribs to be varied to provide a clearance to best accommodate the particular product being sorted.
