Patent number: 4460305Abstract: A strip stacker for stacking in parallel planes, plate like strips of electronic components. The machine has a trap door onto which the plate like strips are placed in succession. Each time a strip is placed on the trap door its position is sensed by an electronic eye which actuates a motor to swing the trap door down allowing the strip to fall down a slide with its lower edge into a tray. A compacter bar is slideably supported in the tray and two locating pins project into the tray to hold the strips already stacked in position as the compacter bar retracts. Each time a strip falls from the trap door the compacter bar is retracted, the pins retract, and the compacter bar extends forcing the strip against the end until the fallen strip is in position behind the locating pins and pushing the tray down the slides. The locating pins extend holding the last strip against its predecessors. When the tray is full it will be at its lower extreme position and will be removed.Type: GrantFiled: July 6, 1982Date of Patent: July 17, 1984Assignee: Automated Industrial Systems, Inc.Inventor: William J.

Patent number: 4361318Abstract: Apparatus and method for controlling the speed of the conveyor on which a stack of sheets is being collected. A first conveyor moves a stream of sheets into a stacker and onto a second conveyor which moves the stack away from the incoming stream. The stream is moved around a drum which forms a part of the first conveyor and a second conveyor receives the stack and moves at a speed which accommodates the growth of the stack. A sensor detects the thickness of the stream of sheets, and another sensor detects the speed of the first conveyor, and the two sensings are transmitted to the drive for the second conveyor so that the second conveyor is moved at an automatic and appropriate speed to accommodate the incoming stream of sheets.Type: GrantFiled: July 9, 1979Date of Patent: November 30, 1982Assignee: Stobb, Inc.Inventor: Walter J.

Patent number: 4275875Abstract: The mail sorting machine of the present invention is capable of receiving a supply of envelopes in a magazine from which the individual envelopes are picked off in succession by means of a suction device operating in combination with a pair of conveying belts having a friction surface facing the incoming envelopes. The suction device acts through holes in the conveying belts to draw the lead envelope against the friction surface of the conveying belts for separation of this envelope from the rest of the supply. The separated envelope is then transferred to a read station where a reading device reads a sort code imprinted on the envelope. The envelope is then provided to the storage section of the machine where it is directed to its designated sorting bin. The storage section of the machine is provided with a plurality of diverter mechanisms which are arranged in pairs to form a guideway through which the envelopes are directed.Type: GrantFiled: December 28, 1978Date of Patent: June 30, 1981Assignee: Bell & Howell CompanyInventor: Roy Akers

Patent number: 4273491Abstract: Apparatus for stacking and storing a plurality of flat objects, such as letters. The apparatus includes at least one storage box and a loading device designed to transport the flat objects from a source and to project them into the interior of the box. The box and loading device are respectively positioned so that the flat objects are projected into the box at an incline with respect to its bottom and a portion of each object's leading edge impacts a stopping surface formed in one of the side walls of the box. This impact imparts a rotational couple to the object which brings the lower edge of the object into firm engagement with the box bottom. The object is then moved onto the stack of similar objects being formed in the box, either by gravity or an auxiliary device. In one preferred embodiment, relative movement is provided between the box and loading device so that the objects can be projected into the box at a point close to the top of the stack.Type: GrantFiled: April 14, 1978Date of Patent: June 16, 1981Assignee: Agence Nationale de Valorisation de la Recherche (ANVAR)Inventor: Jacques Roux

Patent number: 4258909Abstract: Apparatus for the conversion of a stream of partly overlapping sheets into a row of fully overlapping sheets has a first conveyor which transports a growing row of sheets at right angles to the planes of the sheets, and a composite second conveyor which defines a downwardly extending path wherein successive sheets of the stream descend onto the first conveyor to accumulate between spaced-apart distancing elements of the first conveyor. Successive sheets of the stream are engaged and pushed forwardly on the first conveyor by an oscillating pusher which, when retracted, provides room for descent of a sheet onto the first conveyor behind the rearmost sheet of the growing row. The amplitude and/or frequency and/or the end positions of the pusher are adjustable to account for variations in thickness and/or stiffness of sheets in successive streams and/or for differences in friction between the sheets and the second conveyor.Type: GrantFiled: February 23, 1978Date of Patent: March 31, 1981Assignee: Grapha-Holding AGInventor: Hans Muller
