The present invention relates to a device for handling metal tape rolls with a frame pivotably arranged about a substantially horizontal axis, on which at least a mandrel, the axis of which is perpendicular to the pivot axis of the frame, is rotatably arranged.

In a known device of this type, only one mandrel is attached to the frame, which is in the vertical position is connected to a drive device. The drive device is used here just to rotate the mandrel. To bring the mandrel into a horizontal position, the frame can be pivoted by 90 °. The pivoting of the frame must be carried out by hand, with then the mandrel comes out of engagement with the drive device.

The operation of the known device is made possible by the absence of a drive device for the pivoting of the frame made more difficult, and such a device would also not be suitable suitable to be used in a production line in which heavy metal belt rolls in the horizontal position of the Domes placed on top of these to be unwound in a vertical position and, vice versa, built-in to become.

Furthermore, devices for winding metal tape rolls have also become known at which on a frame pivotably arranged about a vertical axis are two opposite to each other

The roller bearing on the mandrel 15 with the larger diameter supports a circular table 37, which guides it, and the open roller is then supported by means of the bevel gear 38, which is wound tightly on the mandrel 15 with the top drive motor 16 . mentioned bevel gears 31 and 32 is in engagement. When the end of the roll so rewound io The clutch 85 shown in FIG. 3 is reached, the winding machine 3 is through 90 ° and will be described in detail below, direction of the arrow in FIG. 1 rotated around the mandrel is used to align the bevel gear 38 with the table 37 15 so that the tightly wound, treated to connect or separate from the table. In the same way, the roller bearing 36 carries a similar, circular output side of the winding device, that is to say against the 15-shaped turntable 39, which is directed via a clutch 86 conveyor 29. The tape roll lift truck is connected to the bevel gear 40, which Kegel-10 is moved into the correct position below the tape roll wheel in a similar manner with the bevel gears 31 and on the mandrel 15, and the platform 11 32 is in engagement.

go all and the motor and the winding unit 3 held by the action of the brake 17 on the shaft of the motor in the rest position. The locking pin 49 is pushed by means of the hydraulic cylinder 50 into the counterpart 48, 48 'or into the third counterpart mentioned above, whereby the winding unit 3 is fixed in the desired position. When the winding unit 3 is in the vertical position according to FIG. 2 and the brakes 30-30 α and 17 are released, the drive motor 16, which drives via the reduction gear 19 and the shaft 23, can be operated to rotate the bevel gear 32 , which in turn sets the bevel gears 38 and 40 in rotation. It can be seen that, since the braking device 30-30 α has been released, the bevel gear 31 can rotate freely and consequently, when the clutches 85 and 86 are engaged, the turntables 37 and 39 as well as the mandrels 9 and 15, the connected to the bevel gears 38 and 40 rotate in opposite directions. If one of the clutches 85 or 86 is disengaged by actuating the valve 45 'or 46', then the corresponding turntable and mandrel is separated from the drive gear 38 or 40 and remains in the rest position. Such disengagement of the clutches is preferably carried out when a mandrel is in its non-working, vertically downwardly directed position (see mandrel 15 in FIG. 2) and when strip material from a mandrel which is in its vertically upwardly directed position Location is withdrawn. It can be seen that the arrangement described above allows a selectable vertical position fixing and a rotation or non-rotation of the radially adjustable mandrels 9 and 15 either for the unwinding or the tight winding of a roll of metal tape. Moreover, this arrangement allows the winding unit 3 to be rotated as a whole in order to bring the mandrels 9 and 15 into a horizontal position in order to simultaneously place a tape roll to be treated on one mandrel and to remove a treated tape roll from the other mandrel. It will of course be recognized that other constructions employing the same inventive principle but employing different means can be used to achieve the same result. The F i g. 4 shows a modified form of the device for processing and handling metal strip rolls, which is specially designed to receive tightly wound strip rolls, the axes of which are horizontal, from a conveyor and to hold them precisely and to transfer them to a further treatment device, such as a rolling mill, during the unwinding. to support. When setting up according to FIG. 4, a chain conveyor 120 is provided to bring tightly wound tape rolls 121 into a position in which they can be removed from the platform 122 of a lifting and conveying carriage 123, which carriage 123 is generally similar to that shown in FIG. 1 shown carriage 4 and its platform 7 may be similar. The tape roll handling unit according to FIG. 4 comprises a substantially cylindrical housing 124 which carries support or rotary tables 125 and 126 at its opposite ends. Radially adjustable mandrels 127 and 128 are arranged on the support tables 125 and 126 and are rotatable with them. Couplings, similar to couplings 85 and 86 of FIG. 1 to 3 are provided in order to control the drive connection to the mandrels 127 and 128 independently of one another. The housing 124 is supported on a horizontal shaft 129, rotatable about its transverse axis. The drive motor 130 is connected by a suitable gear train 131 so that the housing 124, the tape roll support tables 125 and 126 and the mandrels 127 and 128 can be rotated as a unit about the horizontal axis of the shaft 129 and the mandrels 127 and 128 about theirs own axes can be rotated when the above-mentioned clutches are engaged. A rolling mill 132 with four rolls arranged one above the other is provided, to which strip material is fed from a strip roll supported on the mandrel 128, when the device in the mode shown in FIG. 4 is the location shown. As can be seen in the figure, strip material is drawn from roll 133, which is supported on mandrel 128, through rolling mill 132, and mandrel 128 and support table 126 are preferably connected to the drive and driven at the desired speed. While the strip 133 was being unwound in the direction of the rolling mill, a strip roll was removed from the conveyor 120 by means of the conveyor carriage 123. The carriage is displaced along its rails 123 'until the tape roll is placed on the now stationary, non-rotating mandrel 126, which is then expanded radially. The platform 122 is then lowered and the carriage 123 is withdrawn. After the tape roll 123 has been completely unwound, the entire unit, as seen in FIG. 4, is rotated counterclockwise by 180 °, so that the positions of the mandrels 127 and 128 are interchanged. The strip of roll 134 is then in the correct position to be fed by the rolling mill 132 and the mandrel 127 is rotated to unwind the strip against the rolling mill. During this work process, the lift truck 123 removes a further roll of tape 121 from the conveyor 120 and places it on the mandrel 128, which is now stationary. This cycle continues as long as the system is in operation. Essentially the same device as in FIG. 4 can also be used to wind strip material produced by a rolling mill or other treatment device and to feed the rolls formed to a conveyor. In such a process, the strip material would then be contrary to the direction of the arrow in FIG. 4 run and are wound on the driven mandrel 128. In such a winding operation, the housing 124 and the mandrels are rotated clockwise to reverse the position of the mandrels 127 and 128 when the complete roll of tape is formed, and the tape roll just formed is then removed from the mandrel 128, which has been stopped, by means of the Carriage 23 taken away and brought to the chain conveyor 120 and transported away by this. In the meantime, the end of the strip coming from the rolling mill is tied to mandrel 127 to form another roll of strip. Patent claims: 1.
