  • Patent number: 5101982
    Abstract: The conveying and off-loading apparatus, used in machines for the automatic selection and distribution of products, comprises a conveyor for transporting individual products from examination stations to discharge stations along a path, including an elongate flexible closed-loop belt and a plurality of rollers distributed on the conveyor. The rollers have axes extending transversely to the longitudinal extension of the conveyor, and adjacent rollers define between one another elongated holders for individual products. Forks rotatably support the rollers on the chain and are adapted to allow small vertical oscillations of the rollers, as the weight of the product and its holder is lifted from the chain and transferred to a level section of the ramp associated with a weighing device at an examination station. The forks are mounted along the chain and oscillate about an axis parallel to the path. The rollers are selectively tiltable for off-loading a product from the conveyor at one of the discharge stations.

  • Patent number: 4943369
    Abstract: A method and apparatus for combining a plurality of serially supplied sheets into a set, depending on markings carried by the sheets and read by a reader, and discharging a set to a further handling station, such as an inserting machine. The leading edge of the first sheet of a set, and successively the remaining part of the sheet, is deflected out of its plane of transport, preferably downwardly and through about 180.degree., into a new plane of transport, in which the sheet is arrested in a flat condition. Each subsequent sheet of a set is similarly deflected and displaced into a position overlying the preceding sheet, and after thus completing the set, it is discharged. At choice, a set can be discharged with the leading edges being the edges that were the trailing edges during the supply of the sheets, or with one of the feed side edges of the sheets in leading position.

  • Patent number: 4934685
    Abstract: Two stacks of sheets are supported by a tray, one stack resting directly on the tray and the other stack being on top of the first stack. The two stacks of sheets are separated by a stack separation roller that rests on the top of the first stack of sheets and is engageable by an edge of the second stack of sheets to thereby offset the stacks of sheets. Sheets are fed seriatim from the bottom of the first stack until all sheets of the first stack are removed. When the first stack of sheets has been fed from the tray, the separation roller is raised and the second stack of sheets is moved to the position previously occupied by the first stack. Then the second stack of sheets is fed seriatim from the tray.

  • Patent number: 4928945
    Abstract: A sheet collating machine includes feed-up devices (7) disposed at bins (1) and having driven feed-up wheels (8), the feed-up devices being pivotal between a lowered position in which the feed-up wheels engage stacks (2) of paper sheets and a raised position in which the wheels are disengaged from the stacks. A conveying path (3) is defined by a plurality of conveyor and press rollers (4), along the upper side of which a corresponding number of backing rollers (6) are disposed, and a conveyor belt (5) runs between the rollers. A sensor (12) is actuated by a spring member (11) which extends crosswise over the conveyor path when no sheet protrudes between the press roller and the belt, and the spring member is lifted from its contact with the sensor when a sheet passes the latter. When no sheet is advanced within a predetermined period the sensor furnishes a signal to a control device which automatically causes a drive device to lift the feed-up device to its raised position.

  • Patent number: 4926996
    Abstract: A token handling device transmits, using an electromagnetic carrier, data, clock pulses and power to a token. The token transmits data by varying the degree of absorption of the carrier in synchronism with the clock pulses. These data transmissions are detected by a receiver in the token handling device, the sensitivity of which is adjusted each time a token is received. The token could be used in transactions in place of coins, or alternatively could be used for identification purposes in other areas. Data stored by the token could be used to change the way in which the token handling device operates. The token handling device may for example form a vending machine, and the token could be used to alter the pricing of goods vended thereby. The token handling device may be combined with a coin validator, in which case there is preferably a common path from an entrance slot for carrying both the tokens and the coins to appropriate testing apparatus.

  • Patent number: 4919413
    Abstract: Each interfaced loader and metering hopper combination of a newspaper assembling system includes improvements for producing ridges in the newspapers at various states where separation of the newspapers from one another is required. The ridges enhance separation by stiffening the newspaper and reducing the area of contact and thereby the friction between them. At the receiving region of the loader, an arrangement of parallel side and central conveyors, wherein the central one is at a higher level than the side conveyors, produces ridges when the newspapers in a stack are fanned back into a stream. A pair of superimposed center conveyors and inclined laterally located arms produce ridges in the newspapers as they are discharged one at a time from a discharge region of the loader into a receiving zone in the hopper.
