Abstract

The invention relates to a device for receiving, transporting onwards and unwinding coils of rolled strip (WB) which are successively transported to the device from a strip rolling mill or a rolled strip storage unit. The device consists of a carousel-type support (KT) which can be driven in rotation about a vertical axis (VA) and on which a pair of radially projecting, rotationally mounted support mandrels (TD) with axial locking elements are located, these support mandrels being angularly offset from each other about 190°. The carousel support (KT) pivots the support mandrels out of a receiving position (A) for the coils of rolled strip (WB), into an unwinding position (C), about a pivot angle of 180°. The carousel support also has at least two other support mandrels (TD II and TD IV) which are offset from the two aforementioned support mandrels (TD I and TD III) by 90°, respectively. Other processing positions (B and D) for removing the coil binding strip and marking or applying the coil binding strip are provided between the receiving position (A) and the unwinding position (C) and between the unwinding position (C) and the receiving position (A) of the support mandrels (TD I, TD II, TD III, TD IV), angularly offset about 90°, respectively.

Description

The invention relates to a device for receiving, for further transport and for unwinding successively from a rolled strip line or Rolled strip collars transported to a rolled strip warehouse, consisting of a Carousel carrier rotatable about a vertical axis, with four of them around 90 ° against each other angularly offset, radially projecting, rotatably mounted Supporting mandrels, with axial locking elements, these each from a receiving position for the rolled strip coils by a certain pivoting angle in a decrease or unwinding pivots.

Devices are already known with which a zoom out of a roll line Rolled strip on a arranged on the carousel, rotatably drivable Tragdorn wrapped to a bunch, with the carousel carrier in another Position brought and the rolled strip collar in this position again unwound (EP-A-0 576 890 and FR-A-1 158 457). After another known Suggestion are on a pair of spaced carousel each four around the 90 ° against each other in a circle offset Tragdome arranged, and between the two Carousel carriers provided a strip scissors. The arrangement serves to to postpone rolling towers of the one carousel carrier one after the other, their tapes under unwinding the strip scissors feed and the thereby resulting strip to feed the mandrel of the other carousel carrier and to wind it up (US-A-2 202 883). The proposal is also known in a rolled strip line between two rolling mill trains a carousel carrier provide, each two, spaced from each other, against each other rotatably wound winding reel pairs wearing. The arrangement serves that from the a rolled stand sequence of the rolling strip line conveyed rolled strip in the to wind up the first pair of coiled yarns and, if necessary, z. B. to treat it afterwards the second Wickelhaspelpaar forward for further treatment and from this to the other Walzgerüstfolge deliver (DE-C-972 603). After one further suggestion are arranged on the carousel carrier Use support arbors with a floor conveyor or on a walking beam transported in a horizontal center axis brought Walzbandbunde to mount on one of the support arbors, axially fixing on this and to pivot the Tragdom with the rolled strip in the unwinding position and then to handle the Walzbandbund, in the meantime already the following rolled strip collar on the other in receiving position Support dome can be postponed and fixed on this (US-A-3 870 244).

The invention has for its object to improve this device so that with their application those from the strip rolling mill or from a fret memory coming rolled-strip coils not only received, swung, unwound and be taken off again, but that in cooperation with such pivotal movements further treatments of the on and off again transported away rolled strip can be made, such. B. previously on a federal preparation reel the federal inspection, attaching Waistband tapes or the removal of the waistband tapes, the waistband marking, the waistband weighing etc.

This object is achieved in that the carousel carrier at least two between the receiving position and the unwinding position, each angularly offset by 90 °, Positions with facilities for waistband tape removal, waistband marking and for waistbanding. In this case, as the invention further provides, in the region of the unwinding a stationary arranged, with the respective opposite Tragdorn drehkuppelbarer rotary drive can be provided. Further, in the region of this unwinding position in the trajectory of the unwound Bundbandes a band scissors are provided. Behind the band scissors can arrange a straightening device. This training according to the invention The device requires significantly less space and less effort for the foundations, and it eliminates some of the previously necessary intermediate transports the rolled strip coils and the necessary recording and Transport equipment.

The invention is based on the embodiment shown in the drawing explained in more detail.

As can be seen from the drawing, are rotatable on the, about the vertical axis VA Carousel KT, here four Tragdome TDI, TDII, TDIII, TDIV by 90 ° angular offset arranged to each other. These are in a manner not shown to its longitudinal axis rotatably mounted in the carousel KT. Everyone Tragdom TD has a locking device RV for axially fixing the on on the mandrel deferred rolled strip bundle. With the rotation of the carousel carrier KT in the direction of arrow S, the carrying dome can be successively, starting with the position A in each case by 90 ° in the following positions B, C. and D pan. In position C is the pivoted support mandrel, here TDIII, axially opposite one, displaceable in the axial direction or swivel Coupling device KV in a fixed drive housing AG arranged.

The device operates as follows: On the, located in the position A. Tragdorn I is a, for example. From a strip rolling mill or a rolling strip storage coming, with lifting beams or other conveyors, dash-dotted lines, indicated Walzbandbund WB postponed, axially fixed by means of the locking device RV and a collar processing subjected, e.g. an inspection. Then the carousel carrier swings KT around the vertical axis VA by 90 ° in the direction of the arrow S and brings the rolled strip collar WB in position B. In this position, the rolled strip collar WB can be treated further, for example, the binding tape can be removed become. The next pivoting movement of the carousel carrier KT by 90 ° pivots the rolled strip collar WB in the position C. In this is the supporting mandrel I by advancing the coupling device KV in a direction of the double arrow P coupled with this and thus created the opportunity that unwound line BD indicated by the rolled-strip band, if necessary the beginning of the tape BD with the help of the unwinding behind the Walzbandbund arranged scissors BS separate. The after the separation process on the support mandrel I remaining rolled strip collar WB is then through the following pivoting movement of the carousel KT again by 90 ° in the Position D driven and after further treatment, e.g. Applying the Binding tape, marking, etc. deducted from the mandrel TDI and re-use fed. In the course of these treatment steps can already during the first further treatment of the pivoted into the position E Walzbandbundes WB the following Walzbandbund WB on the next free Tragdom TDII be deferred, which is now in the position A. and then with the next pivoting movement of this mandrel TDII in the Position B, the following rolled strip collar WB on the free Tragdom TDIII, the in the position A is pivoted in, etc. The rolled strip coils WB of a string sequence In this way, you can simultaneously have four different ones in one time span Treatments are subjected.
