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 present invention relates to a device for receiving, continuing to convey and opening rolling strip coils continuously delivered from a rolling strip production line or a rolling strip warehouse, comprising a rotating support driven to rotate about a vertical axis, the support The seat has four radially protruding and rotatably supported supporting mandrels with axial locks, which are staggered by 90° from each other. Rotate through a certain angle to reach an unwinding or unwinding position.

Background technique

Devices are already known with which the rolled strip from a rolling line is wound onto a support mandrel arranged on a swivel support and driven in rotation to form a strip coil which is rotated by The support comes to another position and opens this rolled strip coil (EP-A-0 576 890 and FR-A-1 158 457) on this position again. According to another known proposal, on a pair of spaced swivel supports, in each case four bearing mandrels are arranged circularly offset by 90° relative to one another, and between the two swivel supports a belt cutter is arranged. This device is used to push the rolling coil continuously back and forth onto the supporting mandrel of one of the rotating supports, the strip of which is sent to the strip shearing machine while being opened and the strip thus formed is conveyed to the The supporting mandrel of another rotating support is wound on this mandrel (US-A-2 202 883). It is also known to propose that in a strip rolling line, a swivel bearing is arranged between two rolling trains, which is equipped with two pairs of coilers spaced apart from each other and offset in rotation relative to each other. This device is used for coiling in the first coiler the rolled strip from a rolling mill train of the rolling strip production line and if necessary, for example processing, then, it is sent to the second coiler, so that For further processing and thus to another rolling train (DE-C-972 603). According to another proposal, support mandrels arranged on swivel supports for rolling coils brought in by floor conveyors or step feeders and placed in a horizontal central axis position to one of the support mandrels shaft and is fixed axially on the mandrel, the supporting mandrel rotates together with the coil into the uncoiling position and then unrolls the rolled coil, here, in the process, it is already possible to push the subsequent rolled coil into On the other supporting mandrel in the receiving position and fixed on this mandrel (US-A-3 870244).

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 accomplished in that the swivel bearing has at least two positions offset by an angle of 90° each between the receiving position and the uncoiling position and having devices for strip removal, strip marking, and strip binding. 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 arrangement 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.

Specifically, a device for receiving, continuously conveying and opening rolled strip coils continuously sent from a rolling strip production line or a rolling strip warehouse is proposed, which includes a rotating support that can be driven to rotate around a vertical axis The support has four radially protruding and rotatably supported supporting mandrels with axial locks, which are staggered by 90° from each other. The receiving position of the coil is rotated to an uncoiling position or an uncoiling position, which is characterized in that between the receiving position and the uncoiling position of the support mandrel, the swivel support is provided with an angle of 90° for adjusting the rolling strip. The location of the device for additional processing of the coil for strapping removal, coil marking or coil binding.

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 supporting mandrel TDI, TDII, TDIII, TDIV 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 the pivoted bearing mandrel, here the bearing mandrel TDIII, there is arranged a connecting device which can slide or be pivoted in the axial direction in a stationary drive housing AG KV.

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 TDI at position A, the rolling coil is axially fixed 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 rotary support KT through 90° rotates the rolling coil WB into position C. In this position, the supporting mandrel TDI is connected to the device by advancing the connecting device KV in the direction of the double arrow P, and thus creates the possibility to open the coil as indicated by the dotted line The strip BD shown, and perhaps by means of the shear BS arranged behind the rolling coil in the uncoiling direction, the strip BD head is cut off. Then, the rolled coil WB left on the support mandrel TDI after cutting the head continues to rotate 90° through the rotary support KT to come to the position D, and after further processing such as bundling, marking, etc., it is removed 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 B, which supports The mandrel is now in position A and with the next turn of the support mandrel TDII into position B the subsequent rolling coil WB is pushed onto the free support mandrel TDIII, which has 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.
