Definitions

• the invention relates to a device for selectively rolling up intermediate rolling stock, unrolling and moving the formed coils or for unrolling the intermediate rolling stock with a bending roller device which gives the rolling stock through it a downward bend and a roller table whose driving rollers support the winding process and unwinding processes and a further development Coils to release the winding position and with a continuous or unwound intermediate rolling driver.
• Coil can be lifted from the winding position into an unwinding position.
• the preliminary strip is unwound from the coil, so that at least the areas of the preliminary strip which are in the
• Coil transfer devices have also been proposed in which the coils are moved from the winding position into the unwinding position by appropriately tilting or lifting the roller table rollers. The problems with pulling off the coil, especially when it becomes smaller, could not be solved here either.
• the invention has for its object to develop a generic device so that an inexpensive operation of this device is guaranteed and that no scrap is generated when operating.
• At least one roller is provided which runs on the circumference of the coil to be transferred or transferred into the unwinding position and holds the coil in the unwinding position.
• the roller ensures that the coil is safely transferred to the unwinding position without rolling against stops, and that the coil remains securely in the unwinding position during its complete unwinding phase, so that the rest of the coil cannot get into the downstream driver.
• rollers of the roller table and the rollers supporting the circumference of the coil are designed to be displaceable in a power-operated manner in the intermediate rolling direction, the roller running on the circumference of the coil can already move the coil against unwanted movements in the intermediate rolling direction during the transfer movement from the winding position into the unwinding position to back up.
• the load-bearing rollers are arranged in a common carriage and the carriage is provided such that it can be moved in the intermediate rolling direction, it is ensured that the coil does not have to be moved or rolled over several rollers of a roller table during its transport, so that considerably less damage is caused to it outer turns of the coil can be caused.
• the supporting rollers can additionally be displaced vertically via at least one drive and can be lowered with decreasing coil diameters, a control device being provided for the drive, which supports the support rollers depending on the coil diameter and / or the unwinding length and / or the Unwinding time reduced vertically.
• the support position of the supporting rollers can be optimally adapted to the coil diameter, so that even the smallest coil diameter can be securely supported.

• the winding station 1 is a known thornless downward winder, in which the band 3 entering the winding station 1 is deflected upwards by means of input rollers 4, 4 '.
• the bending roll 5, 5 ', 5 "gives the strip 3 a downward curvature.
• the strip 3 is wound into a coil in the winding chamber 8 formed by the rolls 6, 6' and 7, 7 '.
• Both the input rollers 4 and the roller 7 ' can be lowered from the shown raised position to the level of the roller 6' and the roller table roller 9. In this position, the rollers 4, 9, 6 ', 7 and 7' form a roller table, via which the belt 3 can be guided through the winding station 1 without being deflected.
• the winding station 1 is assigned a coil opening device 10 which, after the coil has been wound in the winding chamber 8 and the direction of rotation of the driven rollers 7, 7 'can be pivoted against the coil in order to open the coil and the beginning of the strip with the peeling knife 11 to lead to the unwind station 2.
• the unwinding station 2 consists of a carriage 12 and a stand 13, in which the driver rollers 14, 14 ', 14 "of the driver 16, which can be set by means of a piston-cylinder unit 15, are mounted.
• a displacement cylinder 17 for the carriage 12 engages on the stand 13
• a roller 20 which can be adjusted in its horizontal direction by means of a piston-cylinder unit 18 and in its vertical direction by means of a piston-cylinder unit 19 is articulated on an angle lever 21.
• the stand 13 also has a roller table roller 22 on the tape 3 is fed to the driver 16.
• rollers 4, 7, 7 'and 23, 23' must be lowered to the roller table level, so that a roller table results from these rollers and the rollers 6 'and 22, via which the belt 3 from the inlet of the winding station 1 directly to Driver 16 can get.
• the tape 3 is fed from the input rollers 4, 4 'and the bending rollers 5, 5', 5 "into the winding chamber 8, where it is wound into a coil.
• the roller 7" is still in for winding the coil the raised position shown.
• the roller 7 ' is lowered to the roller table level and the coil is only carried by the driven rollers 7, 7'. In this position, the coil is completely wound.
• the coil driven for winding in a clockwise direction is driven counterclockwise after its completion by reversing the direction of rotation of the driven rollers 7, 7 '.
• the tape bundle opening device 10 is pivoted against the coil, so that the former tape end is now peeled off from the coil as the beginning of the tape and fed to the driver 16.
• the displacement cylinder 17 has been extended so that the carriage 12, on which there is no longer a coil 24, reaches the roller 7 '. has approached.
• the roller 20 is pivoted by means of the piston-cylinder units 18, 19 in the direction of the winding station 1 into a position against or approximately against the coil located there.
• the coil 7 is transferred from the winding station 1 onto the rollers 23, 23 'of the carriage 12 into the unwinding station 2 by lifting the roll 7.
• the roller 20, which can optionally be pivoted back in the direction of the stand 13 during the transfer process, ensures that the coil 24 cannot roll beyond the roller 23 '.
• the carriage 12 and the roller 20 are moved in the direction of the stand 13, so that the winding station 1 is free for winding a new coil.
• the roller 20 can be adjusted vertically by means of the piston-cylinder unit 19 so that even a very small residual coil is securely supported by the roller 20, so that the residual coil does not enter the driver 16 can be moved.
• Fig. 2 shows a roller 20 'similar to roller 20, which, however, can only be adjusted essentially horizontally via a piston-cylinder unit 18'. So that the remaining coil 24 'cannot be drawn into the driver 16', a lever 25 is provided which can be pivoted towards the belt 3 'via a piston-cylinder unit 26.
• the lever 25 has rollers 27, 28, the roller 27 being pivotable relative to the roller table 22 'and the roller roller 22' and the roller 27 enclosing the belt 3 'between them.
• the support roller 28 is arranged at the tip of the lever 25 so that it rests against the rest of the coil 24 without touching the band 3 'in the driver inlet area.
• FIG 3 shows a further alternative, by means of which it is ensured that the coil 24 "is completely unwound.
• the essentially horizontally pivotable roller 20" ensures that the coil is securely on the carriage 12 ". remains.
