Definitions
- the present invention relates to a device with flow medium storage for positioning and / or transporting piece goods, in particular flat piece goods, in which device a loadable fluid cushion, in particular air cushion, can be built up over a support surface for the piece goods, for which openings in the support surface via channel means with a
- the fluid pressure source is in fluid communication.
- Such devices are advantageous to sensitive goods, such as paper webs or glass panes, such as records and CDs, but also silicon wafers for semiconductor construction u. to position or treat gently and without contact because of .
- the openings provided in the support surface and connected via flow means to the generally compressed air source are nozzles which press the air under the piece goods, which is then held in suspension by the air.
- a large number of nozzles are required, in particular for large areas, which cause high system costs and high fluid consumption.
- Such systems are also used in so-called clean rooms, where a weak air flow directed downward from the ceiling is maintained in order to prevent dust and the like. hold down, the punctual air outlet from the nozzles creates disruptive, counterproductive air turbulence.
- At least a part of the support surface is formed by bodies which are permeable to flow medium and made of a sintered material, which bodies can be connected to the pressure source via channel means Breakthroughs are used.
- the choice of the sintered material, such as coal, ceramics and the like, the size of the bodies which are permeable to the current, the density of their planar arrangement and the selectable flow pressure allow an optimal adjustment of the quasi-static air cushion for each application.
- the contact surfaces with the bodies that are permeable to the flow medium, made of sintered material form channel-like guideways with lateral borders.
- a major problem is the generation of an effective feed on the piece goods.
- the bearing surface is part of a guide track of a storage conveyor and least a drag conveyor slot is penetrated by minde ⁇ through which flights extend
- the 'per "belt side at least three, mutually in the direction of movement with Distance from one another and vertically offset from one another comprise roller or roller bodies, each of which is partially wrapped around by a belt strap which is continuously rotating and arranged under the guideway, and which together with the belt strap form a slip drive for the driver.
- Rollers or rollers the storage of the rollers or rollers and / or their surface condition.
- FIG. 2 shows a schematic, diagrammatic illustration of the device according to the invention in the form of a storage conveyor.
- the device with fluid storage for positioning and / or transporting piece goods, in particular flat piece goods comprises a support surface 1 for the piece goods and has openings 5 which are connected to the channel means 4 with a
- Pressure source of the fluid usually air
- the bearing surface 1 is formed by fluid-permeable bodies 2 made of a sintered material, which bodies 2 are inserted into the openings 5 that can be connected to the pressure source 3 via the channel means 4.
- a relatively large-area air outlet on the top of the support surface is now possible, which is represented as a flat vertical flow and forms a quasi-static air cushion.
- the choice of sintered material such as coal, ceramics, etc.
- the size of the body 2 which is permeable to the flow medium, the density of their surface arrangement and the selectable flow pressure allow an optimal setting of the static air cushion for each application.
- This illustration shows a accumulation conveyor, in which the support surface 1 is part of a guideway 1 * with side guides 12 and is used to transport CD's, for example.
- a drag conveyor slot 6 extends in the middle of the guideway 1 'for the longitudinal guidance of a plurality of peripheral drivers.
- mer 7 (only 1 driver shown).
- Each driver can be guided with a flat guide piece 7 'in the drag conveyor slot 6 or can be supported on guides on rollers (not shown) in such a way that the drivers can circulate freely along the conveyor line with the system.
- Each driver 7 preferably goes into a chassis on the belt side
- rollers 8 and 9 which can be freely rotating or non-rotatable, are each partially wrapped around by a belt strap 10 and form a slip drive for the drivers 7, the belt strap being generally continuously rotating, which is known per se is and so does not need to be explained in more detail.
- part of the support surface 1 is again formed by bodies 2 made of a sintered material which are permeable to current, which bodies are inserted in openings 5 which communicate with the pressure channel 4 via openings 16 are in fluid communication with the fluid, such as air.
- such air outlets can also be provided in the side guides 12 (not shown) in order to prevent lateral air cushions against the piece goods striking against the side guides.
- a distance-keeping stop means 11 is provided on each driver 7, which interacts with the leading driver 7.
