Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for supplying a coil winding spool for winding a steel plate into a coil.

Generally, in steel sheet manufacturing equipment, rolled steel sheets are wound into a coil. To wind this steel plate, generally a cylindrical coil winding spool (hereinafter simply referred to as spool) is attached to the mandrel of a coil winding machine, the steel plate is wound onto this spool, and the steel plate is finished winding. The coil of cod roe steel plate is removed from the mandrel along with the spool. This spool is then reused.

By the way, conventionally, in order to attach the above-mentioned spool to the mandrel of the above-mentioned coil winding machine, the spool was hoisted by a crane, etc., the spool was placed on a coil carriage for conveying the coil, and this coil carriage was moved. I then attached this spool to the mandrel. However, this spool is heavy and requires a lot of labor to place the spool on a coil truck using a crane or the like, and the work efficiency is low. As a result, there was a problem that the operating rate of the steel sheet manufacturing equipment decreased. Furthermore, since the spools mentioned above are reused, some of them may be deformed or damaged. Therefore, before these spools are mounted on the mandrel of a coil winding machine, these spools must be inspected and, if deformed or the like has occurred, repairs or corrections must be made. However, since this spool is heavy and cannot be easily moved, this inspection work is troublesome.

The present invention has been made based on the above circumstances, and its purpose is to provide a coil winding spool supply device that can easily supply spools and also allow easy inspection of the spools. There is a particular thing.

That is, the present invention provides a tilting table having a rolling inclined surface on which a coil winding spool to be supplied is placed and tilted so that the coil winding spool rolls, and a tilting table having a rolling inclined surface on which a coil winding spool to be supplied is placed, and the above-mentioned rotation of this tilting table. It is provided in a movable inclined surface so as to be freely protrusive and retractable, and has a holding position protruding from this rolling inclined surface, a rolling stop position moved further upward from this holding position, and a retracted position moved downward from the above-mentioned holding position. A movable holder, a holder drive mechanism that drives this holder, and a holder drive mechanism that is provided on the holder and is in rolling contact with a coil winding spool held by the holder to freely rotate the coil winding spool. and a transfer mechanism for transferring the coil winding spool held on the holder.
Therefore, the spools are placed and stored on this tilting table, and the spools are sequentially rolled and held on the above-mentioned holder. In this case, the holding body can rise to the rolling stop position and safely stop the rolling spool. The holder then moves to the holding position and holds the spool. In this case, since the spool on this holder is rotatably supported by a support roller, the spool can be rotated while waiting on this holder until it is next attached to the mandrel. Inspections can be easily performed. In addition, when the spool on this holder is transferred by the transfer mechanism, the holder is lowered to the retracted position, so the holder does not get in the way when transferring the spool. There is no need to lift this spool when transporting it, so
This spool can be transported safely and efficiently.

This coil truck 6 is configured to be moved by rails 5 in a direction parallel to the axial direction of the mandrel 4, and moves while supporting the coil wound on this mandrel 4. It is configured to be removed from the mandrel 4. The coil cart 6 also serves as a mounting cart for the spool A, and the spool A to be mounted is placed on the coil cart 6, and the coil cart 6 is moved to attach the spool A to the mandrel 4. configured to be installed. Note that 7 is a wheel of this coil truck 6.

The spool supply mechanism 10 of the present invention is provided on the side of the coil winding device as described above. below,
The configuration of this spool supply mechanism 10 will be explained with reference to FIGS. 3 and 4. In the figure, reference numeral 11 denotes an inclined table, and the upper surface of this inclined table 11 is formed into a rolling inclined surface 12 inclined toward the direction of the coil truck 6. A plurality of spools A are placed on this rolling inclined surface 12. And this rolling inclined surface 1
2 has a stopper 1 corresponding to the front of each spool A.
These stoppers 13 are each driven by a stopper drive cylinder 14 and configured to project from and retract from the rolling inclined surface 12. In addition, this rolling inclined surface 1
A holder 15 is provided at the lower end of 2. This holder 15 is rotatably connected by a pivot pin 18 and is configured to rotate vertically and protrude and retract from the rolling inclined surface 12.
The holder 15 is rotationally driven by a holder drive mechanism, for example, a holder drive cylinder 17, and is rotated upward from the holding position where it protrudes from the rolling inclined surface 12 and is approximately horizontal. It is configured to be fixedly held at the rolling stop position to which it has moved and to the retracted position which has been rotated downward from the above-mentioned holding position. Further, a pair of support rollers 16 are provided on this holding body 15 . These rollers 16 are arranged on the rolling inclined surface 12 mentioned above.
The holder 15 is configured to rotate around an axis perpendicular to the direction of inclination of the holder 15, and is configured to contact the spool A held on the holder 15 so as to rotatably support the spool A.

Further, a transfer mechanism is provided at the end of the tilting table 11 on the coil truck 6 side. 19 in the figure is a transfer arm of this transfer mechanism,
A pair of them are provided on both sides of the above-mentioned tilting table 11, and are configured to rotate within a plane parallel to the direction of inclination of the above-mentioned rolling inclined surface 12 by means of a shaft 21. A drive arm 23 is attached to the center of the shaft 21, and the drive arm 23 is connected to a piston rod 24 of an arm drive cylinder 25. Further, the tips of the transfer arms are connected by a guide member 26. This guide member 26 has a pair of chuck members 2.
7 is slidably guided in its longitudinal direction, that is, in a direction parallel to the axial direction of the spool A held on the above-mentioned holder 15. These chuck members 27 are moved by, for example, a cylinder mechanism (not shown), and are configured to engage both ends of the spool A on the holder 15 and hold the spool A. The transfer arm 19 rotates between the position shown by the solid line and the position shown by the two-dot chain line in FIG.
is configured to be transferred onto the above-mentioned coil truck 6. Note that this holding body 15 is attached to the spool A.
When transferring the spool A, the spool A is moved to a retracted position so that it does not get in the way when the spool A is transferred.

Next, the operation of this embodiment will be explained. First, a plurality of spools A are placed on the rolling inclined surface 12 of the inclined table 11, and the stopper 13 is made to protrude to hold these spools A so that they do not roll. First, the holding body 15 is raised to the highest raised position, which is the rolling stop position. Then, the stopper 13 corresponding to the endmost spool A is retracted, and this spool A is caused to roll. This spool A rolls on the rolling inclined surface 12, comes into contact with the support roller 16 on the upper side of the slope of the holder 15 at the above-mentioned rolling stop position, and stops at this position. Next, this holding body 15 is lowered to its holding position. As the holding body 15 descends, the protruding height of the support roller 16 on the upper side of the slope from the rolling slope 12 decreases, and the spool A held by the support roller 16 on the upper side of the slope decreases. Gently climb over this support roller 16. On the other hand, the support roller 16 on the lower side of the slope of this holder 15 is
Since the protruding height from the slope is still sufficiently high, the spool A that has climbed over the support roller 16 on the upper side of the slope comes into contact with the support roller 16 on the lower side of the slope and stops, and the pair of support rollers 16 held between. In this state, it waits until it is next mounted on the mandrel 4 of the coil winding machine. During this waiting period, this spool A is inspected. In this case, this spool A is the support roller 16
Since the spool A is rotatably supported by the spool A, it can be easily rotated by hand.
The inspection work becomes easy and efficient. and,
When installing this spool A on the mandrel 4 of a winding machine, the spool A on this holding body 15 is transferred to the top of the coil truck 6 by the transfer mechanism, and this coil truck 6 is moved to attach this spool A to the mandrel. 4 Attach it on top. In this case, the above-mentioned holder 15 moves to its retracted position and retreats from the movement path of the spool. Therefore, the holder 15 does not interfere with the transfer of the spool A, and there is no need to lift the spool A. Therefore, the spool A can be transferred safely and easily, and the efficiency of the transfer operation is also improved.

As described above, the present invention provides a tilting table having a rolling inclined surface on which a coil winding spool to be supplied is placed and tilted so that the coil winding spool rolls; A holding position that is retractably provided on the rolling slope and protrudes from the rolling slope, a rolling stop position that is moved further upward from this holding position, and a retracted position that is moved downward from the holding position.

This device includes a support roller that supports rotatably, and a transfer mechanism that transfers the coil winding spool held on the holder.
Therefore, the spools are placed and stored on this tilting table, and the spools are sequentially rolled and held on the above-mentioned holder. In this case, the holder can rise to the rolling stop position and safely stop the rolling spool. The holder then moves to the holding position and holds the spool. In this case, since the spool on this holder is rotatably supported by a support roller, the spool can be rotated while waiting on this holder until it is next attached to the mandrel. Inspections can be easily performed. In addition, when the spool on this holder is transferred by the transfer mechanism, the holder is lowered to the retracted position, so the holder does not get in the way when transferring the spool. There is no need to lift this spool when transporting it, so
