CN1443099A - Device for receiving and onwardly transporting coils of rolled strip from strip rolling mill or rolled strip storage unit - Google Patents

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 DEG . 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 DEG . 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 DEG , 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 DEG , respectively.

Description

A device for receiving and onward conveying of rolled coils from a rolling strip line or from a rolling strip warehouse

technical field

The invention relates to a device for receiving and continuing to convey and open rolled strip coils continuously delivered from a rolling strip production line or a rolling strip warehouse, comprising a rotary support driven to rotate about a vertical axis, the support The seat has a pair of radially protruding and rotatably supported supporting mandrels with axial locks that are staggered by 180° from each other. The rotating support makes these mandrels rotate 180 degrees from a rolling coil receiving position. ° into a rolling coil uncoiling position.

Background technique

The function of this device (OS-PS 3 870 244) is to roll the rolled strip, which is delivered, for example, by means of a floor conveyor or on a step feeder and placed on a horizontal central axis, to one of the support cores On the shaft and fixed on the mandrel and the supporting mandrel rotates with the rolling coil to the uncoiling position and then unrolls the rolling coil. During this process, the subsequent rolling coil can be pushed onto another supporting mandrel, which is now in the receiving position, and secured thereto.

Contents of the invention

The object of the present invention is to improve this device so that by using this device not only the rolled coils from the rolled strip production line or from the coil storage device can be received, driven in rotation, uncoiled and taken away again, but also In conjunction with such a rotary movement, the incoming and re-delivered rolled coils can be further processed, for example checking on the coil backup coiler, bundling the coils or removing the strapping, stripping label, tape and coil weighing, etc.

This task is achieved in that the swivel bearing has at least two other bearing mandrels which are each offset by 90° relative to the two bearing mandrels, wherein between the receiving position and the unwinding position and between the uncoiling position and the receiving position, Further processing positions for removing straps, marking strips, bundling strips, etc. are arranged offset by an angle of 90°. Furthermore, as the invention also provides, in the area of the unwinding position, a rotational drive is provided which is fixed in position and which is rotatably connected to the respective opposing bearing mandrel. In addition, in the region of the uncoiling position, a tape cutter can be provided on the movement path of the unwinding coil. A straightening device can be arranged behind the tape cutter. The device designed according to the invention requires considerably less space and less capital outlay, and eliminates the intermediate transport of the rolled coils, some of which were previously necessary, as well as the receiving and conveying devices required for this.

Description of drawings

The present invention will be described in detail according to the embodiments shown in the drawings. Figure 1 shows the device of the invention.

Specific implementation form

As shown in the drawing, on the swivel bearing KT rotatable about the vertical axis VA, four bearing mandrels TDI, TDII, TDIII, TDIV are arranged at an angle of 90° relative to each other. These spindles are mounted rotatably about their longitudinal axes in a swivel bearing KT in a manner not shown. Each support mandrel TD has a locking device RV for axially securing the rolling coil pushed onto the mandrel. As the rotary bearing KT rotates in the direction of the arrow S, the bearing mandrels start from position A and rotate through 90° to the subsequent positions B, C and D one after the other. At position C, axially opposite to the pivoted bearing mandrel, here TDIII, there is arranged a coupling device KV which is axially slidable or pivotable in a stationary drive housing AG.

The device works as follows: a rolled strip coil WB, represented here by a dotted line, is pushed, for example, from a rolled strip production line or a rolled strip storage device and delivered by means of a step feed device or other conveying means. To the supporting mandrel 1 at position A, the rolling coil is fixed axially by means of the locking device RV and the coil is processed, for example for inspection. Next, the rotary support KT is rotated by 90° in the direction of the arrow S about the vertical axis VA and brings the rolled strip coil WB to position B. In this position, the rolled strip coil WB can be further processed, eg strapping can be removed. The next movement of the swivel support KT through 90° rotates the rolling coil WB into position C. In this position, the mandrel 1 is connected to the device by advancing the connecting device KV in the direction of the double arrow P, and thus creates the possibility of opening from the rolled coil as indicated by the dotted line and the strip BD head is cut off, perhaps by means of a shear BS arranged behind the rolled coil in the uncoiling direction. Then, the rolled coil WB left on the support mandrel 1 after cutting the head continues to rotate 90° through the rotary support KT to come to the position D, after further processing such as binding the coil, marking, etc., from the support The mandrel is pulled off the TDI and sent for further use. During this processing step, the subsequent rolling coil WB can be pushed onto the next free support mandrel TDII in the first further processing of the rolling coil WB transferred into position E, which supports The mandrel is now in position A and the subsequent rolling coil WB is pushed onto the free support mandrel TDIII with the next turn of the support mandrel TDII into position B, the mandrel TDIII having been turned into position A, etc. A train of rolled coils WB can in this way be simultaneously subjected to four different treatments within one time period.
