Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is useful for processing input coils of rolling equipment or processing equipment, such as cutting the coil band or automatically inserting it into the input cradle car, by using a conventional band cutter lateral movement or coil transfer crane. The present invention relates to a coil transfer device that eliminates time and equipment cost losses due to insertion due to a wire, and quickly aligns the coil using a simple moving beam and enables supply processing.

For example, in order to remove the coil band or to transfer the coil to the entry side cradle roll, it is necessary that the axial center of the coil and the center of the band cutter or cradle roll match. In conventional systems, for example, with a chain conveyor, the coils on the chain pallet are loaded randomly by the crane operator on the line, and the center of the device must be aligned with the center of the coil by some means using a separate conveyor. It won't happen.

In the present invention, the width of the coil is measured when the coil is loaded and transferred onto a moving beam, for example, a walking beam skid, and after the coil is loaded onto an alignment skid connected to a horizontal moving device, the coil is stretched to a desired size. It can be moved in the transfer direction and aligned to the center of the walking beam skid during the next transfer. By this operation, the center of the next fixed skid and the center of the coil can be aligned, that is, aligned, so that subsequent processes such as cutting the coil band or inserting the coil into the cradle roll can be carried out without any problem.

An embodiment of the present invention will be described below with reference to FIGS. 1 to 5.

In Figs. 1 to 3, 1 is an advancing/retracting device such as a fluid pressure cylinder, 2 is a moving beam that is connected to the fluid pressure cylinder 1 and moves at a constant pitch. In this example, a trolley-type walking beam is shown, and 3 is fixed to the walking beam 2. The lifting device 4 is a fixed skid disposed on the base 11, and the fixed skid 4 is a third
As shown in the figure, a coil 7 is placed on top of the fixed skid 4, and two coils are placed opposite each other to automatically align the coil in the longitudinal direction.
As shown in FIGS. 1 and 2, a plurality of sets are arranged in a row in the direction of movement of the coil (arrow in FIG. 2). Note that 6 is a coil pedestal fixed to the upper part of the lifting device 3.

Reference numeral 5 denotes an alignment skid for adjusting the axial direction of the coil, and as shown in FIG. Two large beams are placed opposite each other on both sides of the walking beam 2. Furthermore, as shown in FIGS. 4 and 5, the alignment skid 5 is connected to a horizontal moving device, that is, an alignment cylinder 8 in this example, and the alignment cylinder 8 is held by a fixed bracket 13 and is connected to a position transmitter. 10, the alignment cylinder 8 is moved a predetermined amount based on the signal from the position transmitter 10, and the roller bearing 9 is connected to the roller bearing 9 by the required distance to adjust the alignment skid 5 in the coil axial direction.
The top is movable.

Thus, in the present invention, the coil 7 loaded on the fixed skid 4 is lifted away from the skid 4 by operating the lifting device 3 fixed to the walking beam 2, supported by the coil pedestal 6, and then lifted up by the fluid. By moving the lifting device 3 forward by a fixed pitch using the pressure cylinder 1 via the walking beam 2, the coil 7 is lowered and transferred onto a predetermined position on the fixed skid 4. Then, one coil is sent from the fixed skid 4 to the alignment skid 5, and the coil 7 transferred onto the alignment skid 5 is moved to the center of the next process, for example, in order to align the center of the band cutter with the center of the coil. The position of the coil in the axial direction is adjusted. That is, the alignment skid 5 is held by, for example, a roller bearing 9 (flat gauge), and can be freely moved a certain distance by an alignment cylinder 8 in the transfer direction, that is, the axial direction of the coil, for alignment. The amount by which the coil should be moved for centering in the axial direction is determined by measuring the coil width and sending its signals to a position transmitter 10 attached to the centering cylinder 8 using, for example, a light emitter 12 and a light receiver 12'. The alignment skid 5 is moved by a certain amount, and this movement completes self-alignment of the coil 7 on the alignment skid 5 in its axial direction.

In this way, the coil 7 is aligned in the diametrical direction by being supported by the fixed skid 4, and the coil 7 is aligned in the axial direction by the alignment skid 5. Then, the center of the automatically aligned coil 7 is transferred so that it matches the center of the device installed behind the alignment skid 5, and the coil is transferred to the next step, such as cutting the band with a coil band cutter or transferring the coil to a cradle car. can be perfectly centered by mechanical constant pitch transfer.
