  • Patent number: 4108031
    Abstract: An alignment and stacking arrangement for stampings manufactured in a continuous stamping operation by a stamping machine having a punch and associated punch matrix. At least one stacking channel is arranged in the punch matrix for receiving the stampings with an intermediate stack forming device being associated with stacking channel. The intermediate stack forming device may include at least one locking pawl for reducing the clearance of the stacking channel and/or a mandrel arranged in the stacking channel which is selectively engaged by a holding element during the formation of the intermediate stack. A stacking mandrel or stacking shaft is associated with the mandrel and is displaceable so as to permit a stack of stampings of a predetermined height to be carried away from the stamping machine by a conveyor arrangement.

  • Patent number: 4046264
    Abstract: Apparatus for stacking and intermittently discharging stacks of sheet material for electrical machines and the like. A plurality of mandrels are provided which are successively movable into a position for forming stacks of sheets continually supplied by a horizontal conveyor. A turntable is provided for moving the mandrels into and out of respective sheet receiving positions. In order to accommodate intermediate stacking of the sheets while mandrels are being exchanged, a mandrel tip is provided which is positionable in alignment with the mandrels when in a sheet receiving position. During normal stacking operations, the mandrel tip is supported at the respective mandrel. During exchange of mandrels clamping jaws hold the mandrel tip in position and a slide member is moved into a position so as to hold an intermediate stack of sheets on the mandrel tip.
