8 Device description Intended use / user indications Intended use Goudsmit sheet separators are designed to loosen/separate sticky or oily steel sheets. The magnets force the sheets apart to make sure to lift one sheet at a time. Damage to tool and die is prevented by eliminating accidentally double blank lifting. The sheet separators are suitable for sheets of almost any length, width or shape, including round and asymmetrical products. The permanent magnetic power does not decrease and is guaranteed for several decades. The use of expensive compressed air systems to separate the steel sheets is no longer necessary, as the permanent magnets will do the job at a much lower cost. Use this device only for the above mentioned applications Environmental demands The sheet separator has a heavy casing around the magnet system, which means that no special environmental demands are necessary. Temperatures Suited for outside temperatures of -20 C to 40 C. Make sure that the magnet is not exposed to high temperatures, while this might cause the magnetic power to decrease permanently. See product specifications for maximum product temperatures. The magnet is to be protected against higher temperatures than prescribed, because the magnet might lose magnetic force permanently when exposed to high temperatures Free space The working space surrounding the sheet separator must be well marked out, to avoid any danger for persons passing-by. The marking out must be provided with clear warnings concerning the entrance of the working space. Noise level The noise level of the sheet separator is low. Vibrations The magnet is to be protected against strong external vibrations, because the magnet might lose magnetic force permanently and or the brittle ceramic magnet material might break. Cleaning Cleaning of the magnets should take place regularly, 8

9 Working principle Working Principle As steel sheets are placed against the sheet separator, the powerful magnetic field automatically forces the sheets apart and separates them from one another. When the top sheet is removed, the next sheet instantly moves up. As soon as the sheets are removed from the separator, they are no longer magnetised. The permanent magnetic sheet separators can also be supplied with a (pneumatic) turn on/off system. This is important for automated production processes. Construction The sheet separator has a heavy casing around the magnet system, which means that no special environmental demands are necessary. The construction of the magnet systems make sure that the highest possible separation force is achieved with minimum size. Available models Goudsmit sheet separators are available in several models: Permanent ferrite magnet system for the most common applications Extra strong Neoflux magnet system in a compact design to separate extremely oily or sticky sheets. Pneumatically controlled permanent Neoflux magnets that can be switched on/off by air pressure. Sheet separators for the automotive industry, Installation examples The sheet separators can be placed next to a stack of steel sheets in different ways, with 1 or 2 magnets at a time. Practice will show which placing method functions best. See examples below. 9

10 Assembly examples of permanent and switchable sheet separators Assembly is simple by using the tapped holes on the back of the sheet separators. The arrows on the photo indicate the recommended transportation direction, in which the plates can be best carried off after being separated by the sheet separator. For smaller sheets the best is to place the sheet separator in the middle of the shortest side. Sheet separators that are place opposite of each other ensure that the sheets will float. For an optimal effect the best is to place two sheet separators at the corner(s) of stacks of large steel sheets Application example 1 In the table you will find various technical data that apply to this calculation example. At this workplace, steel sheets are manually placed in a press. The steel sheets are 900 mm long and 600 mm wide. The sheet thickness is 3.0 mm, so we take sheet separators from the series TBSP 03 that separate up to 4 mm. The sheets are oiled and stick to each other. Under these circumstances. TBSP03 sheet separators have a recommended working surface of 26 dm2. Sheet surface area: 9 x 6 = 54 dm2. Number of plate separators: 54 dm2 / 26 dm2 = 2 pieces. By placing the sheet separators opposite to each other the plates float and they are easy to grip. Pull sheet away in direction shown by the arrow. 10

11 Application example 2 In the table you will find various technical data of this calculation example. An automatic manipulator feeds steel plates to a punching machine. The steel sheets are 2500 mm long and 1250 mm wide. The sheet thickness is 2.2 mm, so we take the switchable sheet separators TPSP, which separate up to 3 mm. The sheets are quite clean and only stick slightly together. Under these circumstances TPSP sheet separators have a recommended working area of 34 dm2. In most automated production processes, it is sufficient to spread 50% of the sheet. This is to ensure that only one plate is taken. Surface to be spread: 25 x 12.5 dm2 = 313 x 50% = 157 dm2. Number of sheet separators: 157 dm2 / 34 dm2 = 5 pieces. Placing two sheet separators at a corner ensures a powerful separation at that point. The other sheet separators are distributed evenly on the adjacent sides of this corner. Pull sheet away in direction shown by the arrow. Examples Sheet separator series 11

12 Construction Sheet separators come in many models and types. In this chapter some different types will be shown. TBSP and TGSP standard permanent magnetic model Standard permanent sheet separators come in 2 magnet types / -strengths: TBSP and TGSP TBSP is built up with ferrite (Ferroxdure) magnets TGSP is built up with Neodymium (Neoflux ) magnets TBSP (Ferroxdure) magnets are cheaper and up to 100 C temperature-resistant, but magnetically weaker then the TGSP (Neoflux ) magnets, which are more expensive and only up to 60 C temperature-resistant. TPSP Pneumatically switchable model Compressed air actuates the magnet system, which works as a pneumatic piston inside the solid aluminium housing. A parallel guiding guarantees the plate magnet inside to always move parallel in a robust way, so it will not get obstructed inside the housing. Bigger versions work by a pneumatic cylinder whereby an internal magnet is actuated. Compressed air On Compressed air Off 12

14 Placing, transporting or moving the device Work safely, ensure sufficient working space and use stable and reliable equipment, to ensure that the device can be installed without risk. Use only lifting/hoisting and transport equipment that is in good condition and never exceed the safe working load of the equipment being used. The weight of the device is stated on the identification plate on the device, placed on the housing as a metal plate or a sticker. Only remove the safety pin, fitted on some versions, after installation. Keep the pin in case you need to transport the device again. Dangers of strong magnetic fields. The magnets on Sheet Separators can seriously and permanently injure. Ferromagnetic objects will be attracted, if you are closer than 50 cm to the magnet. Dangers of strong magnetic fields. Do not stack or transport without non-magnetic spacers of at least 40mm. Do not place on steel surfaces Compressed air supply On pneumatically actuated / adjustable sheet separators The compressed air supply must be between 6 to 8 bar. Use 6mm air hoses and fittings. 14
