  • Patent number: 5358232
    Abstract: The method and the device serves for the production of defined stacks of folded or unfolded sheets. The individually supplied sheets are placed on edge onto a horizontal table whereby the separation of the individual stacks is achieved by a separating support that is advanced parallel to the table at the stack forming velocity. In order to be able to separate and individualize product stacks of differently sized sheets without the need for structural adaptation of the device, the formation of a first separating plane defining the beginning of the stack as well as the formation of a second separating plane defining the end of the stack is achieved by a separating support that is insertable between the sheets in a direction transverse to the longitudinal extension of the table. Further supports are completely insertable into the thus formed separating planes.

  • Patent number: 4805890
    Abstract: A machine for handling flat sheets employs a pair of conveyors in series to receive the sheets from a processing machine and to deliver them to a downwardly moving platform to form a stack thereon and to deliver the stack so formed. Both conveyors operate at a predetermined initial speed to deliver to the platform until a predetermined number of sheets is received from the processing machine. At that point both conveyors are speeded up for a short interval to clear the first conveyor and then the first conveyors is tilted upwards and slowed down which stops the flow to the second conveyor and accumulates the sheets on the first conveyor. The second conveyor continues at a high speed to complete the stack on the platform. The sheets are then discharged from the platform. The first conveyor is returned to its original angle of tilt and both conveyors are returned to their original speeds and the platform returns to its original height to start forming a new stack.

    Abstract: Flat products, such as printed sheets, resting in the form of a horizontal stack on two circulatingly driven transport chains are conveyed towards a retention plate serving as a stop of a feeder or feeder attachment. Two circulatingly driven toothed belts are laterally arranged above the transport chains and these two toothed belts define the sides of a conveying channel. The toothed belts hold the printed sheets in their mutually related positions inside the loose stack during their forward displacement. The distance between the mutually facing runs of the toothed belts is less than the width of the printed sheets or the stack of printed sheets. The toothed belts and therefore also the conveying channel terminate at a distance from the retention plate. The printed sheets are held in a curved or bowed configuration in the conveying channel.

  • Patent number: 4625957
    Abstract: A stacking and delivery apparatus for stacks of products such as paper napkins and paper towels includes a magazine into which the products are delivered to form stacks and which supports the stack along a path of product movement. A plurality of fingers are mounted on a conveyor adjacent the magazine, and the conveyor moves a finger into the path of stack movement when a stack is completed and separates the completed stack from the next stack. A drive system for the conveyor moves the conveyor at different speeds during each cycle in which a stack is formed--a first, fast speed at which a finger is quickly moved into the path after a stack is completed, a second, relatively slow speed at which the finger moves the completed stack along the path as the next stack is built up behind the finger, a third, relatively fast speed at which the finger moves the completed stack rapidly along the path, and a fourth speed, which can be zero, during which a completed stack is removed from the conveyor.

  • Patent number: 4516895
    Abstract: A bag forming machine of the top stacking type has means at the stacking station whereby a stack (12) of bags are clamped during high acceleration arising in their transfer from the stacking position at the station to a discharge conveyor (11). By employing high accelerations and clamping the stack can be transferred without interrupting the rhythm of delivery of bags to the stacking station. The bags are clamped at their "cut" ends by a first clamp (14, 15) during stacking and are then clamped at a second clamp (22, 24), moving transversely to the stack so as to apply dragging motions to the stack to move the "cut" ends of the bags away from the first clamp and to present the "weld" ends of the bags at a roll nip (30, 31) which feeds to the conveyor.

  • Patent number: 4460305
    Abstract: 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.

  • Patent number: 4273491
    Abstract: 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.

  • Patent number: 4258909
    Abstract: 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.
