Abstract
Filled wafer blocks are made by feeding preliminary blocks at a lower level to a stacking station and then feeding a wafer sheet coated on an upper side with a spread to that location, gripping them and inverting them as they are laid on the lower block to form a filled block in the production of filled wafers and the like. The filled wafer blocks can also have uncoated sheets laid onto the blocks.
Claims76
A method of making filled wafer blocks in a stacking station, said method comprising the steps of:
- 1) feeding preliminary blocks at a lower level to said stacking station,
- 2) feeding wafer sheets coated on their upper side with spread as coated upper wafer sheets at an upper level to said stacking station,
- 3) grasping a coated upper wafer sheet on its underside, turning it upside down and lowering the reversed coated upper wafer sheet to a preliminary block,
- 4) joining said lowered reversed coated upper wafer sheet with said preliminary block to form a filled wafer block, and
- 5) removing said filled wafer block at said lower level from said stacking station.
A method of making filled wafer blocks in a stacking station, said method comprising the steps of:
- 1) feeding preliminary blocks coated on their upper side with spread at a lower level to said stacking station,
- 2) feeding uncoated wafer sheets as upper wafer sheets at an upper level to said stacking station,
- 3) grasping an upper wafer sheet on its underside, turning it upside down and lowering the reversed coated upper wafer sheet to a preliminary block,
- 4) joining said lowered reversed upper wafer sheet with said coated preliminary block to form a filled wafer block, and
- 5) removing said filled wafer block at said lower level from said stacking station.
A method of making filled wafer blocks in a stacking station, said method comprising the steps of:
- 1) feeding alternatively a preliminary block and at least one wafer sheet being coated on its upper side with spread on a transport level to said stacking station,
- 2) grasping a preliminary block on its uncoated upperside, lifting it from said transport level, lowering it above a coated wafer sheet lying on said transport level and pressing it downwards against said coated wafer sheet to form a filled wafer block lying on said transport level,
- 3) releasing said filled wafer block, and
- 4) removing said filled wafer block from said stacking station on said transport level.
A method of making filled wafer blocks in a stacking station, said method comprising the steps of:
- 1) feeding alternatively a preliminary block and at least one wafer sheet being coated on its upper side with spread on a transport level to said stacking station,
- 2) grasping a preliminary block on its uncoated upperside, lifting it from said transport level and lowering it into a work position above a coated wafer sheet,
- 3) joining said coated wafer sheet with said grasped preliminary block to form a filled wafer block by lifting said coated wafer sheet from said transport level and pressing it upwards against the underside of said preliminary block held in its work position,
- 4) releasing said filled wafer block onto said transport level, and
- 5) removing said filled wafer block from said stacking station on said transport level.
An apparatus for making filled wafer blocks in a stacking station comprising:
- 1) a lower transport device for supplying preliminary blocks and removing filled wafer blocks at a lower level,
- 2) an upper transport device for supplying wafer sheets as upper wafer sheets at an upper level, and
- 3) a sandwiching means for receiving an upper wafer sheet at said upper level, grasping said upper wafer sheet on its underside, turning it upside down, lowering it to a preliminary block and joining said lowered reversed upper wafer sheet with said preliminary block to form a filled wafer block.
An apparatus for making filled wafer blocks in a stacking station comprising:
- 1) a transport device for alternatively supplying a preliminary block and at least one coated wafer block on the same level, and
- 2) a sandwiching means for grasping a preliminary block on its uncoated upper side, lifting it from said transport device, lowering it above a coated wafer sheet and joining it with said coated wafer sheet to form a filled wafer block.
