Definitions

  • the invention relates to a turning device for turning heavy loads, especially sheet metal coils and Cable reels.
  • tilting tables In order to accomplish the described turning process, are Known especially for sheet coils so-called tilting tables.
  • a tilting table discloses Publication of "TECHNICAL DATA SHEET POSITIONERS" by BUSHMAN EQUIPMENT, INC ..
  • Such tilting tables have a Support surface or plate on which a sheet coil for example with a vertical alignment of its axis can be hung up.
  • the contact surface is at least on one side appropriately limited, and the tilt table can be around an axis that is usually close to that Point runs at which the contact surface of the Tables and the limit "hit", be tilted.
  • To the tilted sheet metal coil lies with the tilting process by about 90 ° a horizontal alignment of the axis on the boundary of the table.
  • tilt tables of this type a rotating device through which the entire tilting table is rotatable about a vertical axis, so that after tipping the removal from the same side can be done from which the loading of the tilting table took place.
  • DE 23 28 970 A1 describes a device for replacement known from metal tape rolls.
  • This facility points at least two waves, one on each Tin coil can be attached.
  • the waves are at one Fixed platform that is rotatable about an axis that around is inclined about 45 ° in space. In a typical position one wave vertical and the other wave horizontal aligned.
  • This can, for example, of the Sheet metal coil attached to the horizontally aligned shaft is arranged to pull off the metal strip while the vertically aligned shaft with a new sheet coil is populated. If the metal strip from the one sheet coil is completely pulled off, the platform is turned by about 180 ° rotated so that the previously vertically aligned shaft in reaches the position in which it is horizontal is aligned, and the metal strip can be removed.
  • the device described is not as Turning device can be used.
  • the Exchanging the sheet metal coils required forces and moments comparatively high, since the loads are considerable Distance from the axis of rotation.
  • the invention has for its object a To create turning device for turning heavy loads turning with comparatively low forces and moments in such a way that the situation with regard to the required traffic area improved with little effort becomes.
  • the turning device according to the invention has one Table to put the load on.
  • the Turning device according to the invention determines that the Turning device according to the invention a single table having.
  • the load that is only turned on this and does not have to be exchanged for another load, hung up.
  • the turning movement takes place in such a way that the contact surface of the Tables from their original, horizontal orientation vertical orientation after turning. If accordingly a sheet coil with a vertical Alignment of its axis has been placed on the table after turning it aligned so that its axis is horizontal. In this position is to support the sheet coils turned down a limit required.
  • the table in its starting position i.e.
  • the drive of the table to perform the turning movement done by a drive shaft connected to the table, which, on the one hand, is inclined with respect to the table. To the others the drive shaft runs in the use position the turning device inclined in space.
  • the inclination of the drive shaft is approximately 45 °. This means that the turning device is about 180 ° is to turn a load to be turned from one orientation with vertical axis in alignment with horizontal Bring axis, and vice versa.
  • the respective Alignments of the table and the attached ones lateral limitation in such a way that the Loading and unloading the table from essentially the same Side can be done.
  • the side Limits on the back and one of the two Side edges of the table are designed to be loaded is not hindered from the front.
  • the load to be turned is always reliable through the support surface of the table itself, the side Boundary as well as the rear boundary held.
  • the load lies with the changed one Orientation on the former rear limitation on and can now be removed from the side from which loading has already taken place. This allows in advantageously significantly reduces the traffic areas be, since the turning device according to the invention only from one side must be accessible. This allows the Turning device, for example, in a space-saving manner Can be arranged on a wall.
  • the invention thereon is not limited.
  • the drive shaft at an angle other than runs exactly 45 ° in the room.
  • the inventive turning device in such a corner Space can be arranged that loading from one Side and the unloading is done from a second side offset from the first side by an angle of approximately 90 ° is.
  • this can also be done in an advantageous manner with a comparatively simple structure Turning device a significant reduction in Achieve space requirements.
  • the drive shaft described here runs in advantageously such that the extension of its axis steps through the table.
  • the invention Align the shaft so that its elongated axis stepping through the table leads to the significant advantage that this axis at least near the center of gravity of the Table including the load placed on it can. This results in comparatively low drive torques required because the moment of inertia of the load placed around the axis of the drive shaft can be kept low.
  • the orientation described is also with regard to the burdens and changes in burdens on those involved Components advantageous.
  • the Drive shaft by about 45 °, in particular 47 ° with respect to Horizontal is inclined.
  • split rings or split strips are helpful for those it is essentially cut sheet metal coils is.
  • this split rings or split strips isolated are, with an exactly vertical alignment of the Bearing surface of the table the risk that individual Tilt split rings or split strips forward. This can only through a comparatively complex locking device, with which the rings or bands are clamped on the table be prevented.
  • This measure can be taken at the described preferred embodiment can be saved, by an inclination of more than 45 °, in particular about 47 ° takes place, and with the turning movement only a rotation about 180 ° is carried out.
  • a plain bearing for mounting the drive shaft proven to be particularly cheap.
  • this camp is advantageous from a cost perspective.
  • a plain bearing also offers the Advantage that it supports the braking that in certain Phases of the turning process is required. In other words can reduce the load on the braking devices be that the friction of the plain bearing some Braking effect unfolds.
  • At least one stop is provided.
  • For the stop can be provided in a particularly simple manner that there is a single stop that is from two different sides to the Limit turning movement in each case.
  • a limit switch is preferably provided, the when a defined end position for a Switching off the drive ensures.
  • the limit switch in a safety switch is integrated into this can advantageously be used to reduce the risk a squeeze between individual components of the Turning device and the existing stops prevent.
  • Fig. 1 is an embodiment of the Turning device 10 according to the invention shown.
  • This has a base 12 indicated in the form of a pyramid, on, as explained in more detail below schematically illustrated stop 14 can be present, which can also be used as a support, however is not absolutely necessary.
