Description

[Detailed description of the invention] [Industrial application field] The present invention is a coil wound with a strip of steel, that is,
This relates to the packaging of steel strip coils (hereinafter referred to as coils).

[Prior Art] Traditionally, long steel strips obtained by rolling mills such as strip mills have been rolled with their black crusts and exported as coils, or have been pickled and then exported.
It is rolled up and exported or exported as a coil.

In that case, for the purpose of rust prevention, scratch prevention, and aesthetics,
It is common to wrap the outer circumferential surface of the coil in packing paper. As the packing paper, for example, a slightly thick paper impregnated with a volatile rust preventive agent and coated with nylon is used. Alternatively, use a paper with increased strength, such as by attaching a net-like thread to the paper.

Conventionally, when packing coils with packing paper, the coils are lifted by a lifter installed in the coil transfer equipment line in a packaging line consisting of coil lifting and transfer equipment and coil transfer equipment in a steel factory. A piece of packaging paper that has been cut to length according to the outer diameter of the coil in advance on the side or extension of the packaging line is brought in, and manually inserted under the coil. The outer circumference of the coil was wrapped in paper.

[Problem that the invention aims to solve] Conventionally, the cutting machine that cuts the packaging paper into lengths in advance had to be installed in a location separate from the packaging line, such as next to the packaging line. , an installation space was required for this purpose. In addition, in order to increase work efficiency, it was necessary to cut and store several types of packaging paper in advance, as the outer diameter of the coil varies widely. Furthermore, a lifter device for lifting the coil had to be installed in the coil transfer device line. and,
Therefore, manual work is extremely dangerous, and it is necessary to install a packaging paper cutting device and a lifter device as separate equipment, resulting in high costs.

The present invention aims to eliminate these drawbacks, and makes it easier to supply packing materials for coil packaging, as well as making it possible to use existing coil lifting and transfer equipment and coil transfer equipment with saddles. The method involves placing the packaging material near the end on the saddle of the coil transfer device, placing the coil on top of it by operating the coil lifting and transfer device, and then activating the coil transfer device to move the coil laterally. After that, the coil can be reliably packed with packing material. In addition, in this invention, in order to prevent the coil from unraveling or damaging the outer surface during transportation, the coil can be packed while being moved horizontally instead of being rolled. be.

[Means for Solving the Problems] For the above purpose, the present invention provides a coil lifting and transferring device, and a coil transferring device that extends below the coil lifting and transferring device and has a saddle for placing the coil. A device is provided, and this saddle is provided on the upper surface of the saddle so as to be able to move freely in the horizontal direction perpendicular to the axis of the coil while holding the coil of the steel strip so as not to rotate. A feeder for supplying packaging material is provided at the end of the coil lifting and transferring device at the upper part of the forward movement path of the saddle for transferring the coil provided, and the feeder for supplying the packaging material is used to carry the belt-shaped packaging material. A holder for packaging material that holds a plurality of continuously wound rolls in a direction perpendicular to the direction of movement of the saddle, a feed roll located under this holder for unwinding the packaging material, and a feed roll for unwinding the packaging material. It consists of a guide provided at the bottom for sending out packaging materials, and a cutter for cutting the packaging material installed in the middle of this guide in the vertical direction so that it can be taken in and out, and the feed rolls are rotatable with mutually adjustable pressing forces. It consists of a set of two rolls, and the guide includes two guide plates that narrow downwards above the cutter entry/exit part, and a guide plate that narrows downward in the direction of saddle movement below the cutter entry/exit part. The coil packaging device is composed of a coil packing device and two guide plates whose lower ends extend toward both sides of the rear.

[Operation] First, a coil transfer saddle is placed on standby at a coil unloading position by a coil lifting and transfer device without a coil placed thereon, and a package having a predetermined width is placed in a feeder section for supplying packing materials. Place the lower end of the material in the knife section.

In this state, the coil lifting and transferring device is operated to lift the coil at another location, move it sideways, and then bring it to a position above the saddle.

Meanwhile, the feed roll is operated to unwind the packaging material from the roll and let the lower end of the packaging material fall downward. A worker on the floor grasps the lower end of the packaging material with his/her hand and places the end, or a portion of the packaging material near the end, on the saddle. Of course, it is also possible to place the packing material on the saddle with the end thereof appropriately protruding from the saddle.

In this state, the coil lifting and transferring device is operated to lower the coil onto the packaging material on the saddle. In this case, in order to prevent the winding end of the steel band on the outer surface of the coil from unraveling, it is desirable to place the winding end of the steel band in direct contact with the upper surface of the saddle. After removing the coil,
Return the coil lifting and transferring device to its original location where it will not interfere with the operation of the coil transfer device.

Next, with some of the packaging material and the coil still placed on the saddle, the coil transfer device is activated to move the saddle horizontally toward the packaging material supply side, and the feeder for supplying packaging material is moved. Move it to the position where it passed below. At this time, the feed roller is also activated. The packing material is wound around the outer periphery of the coil one after another as the saddle and the coil traverse.

Then, by operating the feed roll, the packaging material is unwound to a length suitable for the outer circumference of the coil.
Operate the cutter to cut the packaging material to an appropriate length. It can also be configured to disconnect automatically.

After cutting the packaging material, the worker wraps the packaging material around the entire circumference of the coil and secures the overlapping ends of the packaging material with duct tape or the like. Then, the outer periphery is wrapped in one or several places with an outer circumferential band such as a wire, and the coil transfer device is operated again to further transfer the packed coil on the saddle and carry it to a predetermined location. After that, the packed coil is unloaded and the saddle is returned to its original position, completing one cycle.

Next, the operation of this embodiment will be explained.

First, the saddle 10 for transferring the coil is attached to the coil 6.
The packaging material 17 is placed on standby at the position shown by the solid line in FIG. .

In this state, the trolley 5 of the coil lifting and transferring device 1
The tongs 7 are activated to lift the coil 6 that has been transferred to the end of the conveyor skid 9, move it sideways, and then bring it to a position above the saddle 10.

Next, operate the feed roll 20,
The packaging material 17 is unwound from the roll 18, and the lower end of the packaging material 17 is let down. A worker on the floor 12 grasps the lower end of the packaging material 17 with his hands, and places the end or a part of the packaging material 17 near the end on the saddle 10. Of course, the end of the packaging material 17 can also be placed on the saddle 10 with the end thereof protruding considerably from the saddle 10.

Incidentally, the work of bringing the coil 6 to a position above the saddle 10 and the work of placing the packaging material 17 on the saddle 10 can be performed in reverse to make the work safer.

In this state, lower the tongs 7 and remove the coil 6.
It is lowered onto the packaging material 17 on the saddle 10. In this case, in order to prevent the winding end of the steel band on the outer surface of the coil 6 from coming loose, it is desirable to place the winding end of the steel band in direct contact with the upper surface of the saddle 10. The tongs 7 are separated from the coil 6 and the coil lifting and transferring device 1 is returned to the conveyor skid 9.

Next, with part of the packing material 17 and the coil 6 placed on the saddle 10, the coil transfer device 2 is activated to move the saddle 10 to the right in FIG. Move it to the position shown by the chain line or further to the right. At this time, the feed roller 20 is also operated. The packing material 17 is wound around the outer periphery of the saddle 10 and the coil 6 one after another.

Then, by operating the feed roll 20, the packaging material 17 is unwound to a length suitable for the outer periphery of the coil 6, and the knife 28 of the cutter 21 is operated to cut the packaging material 17 to an appropriate length. this is,
It can also be configured to disconnect automatically.

After cutting the packaging material 17, the operator wraps the packaging material 17 around the entire circumference of the coil 6, and fastens the overlapping ends of the packaging material 17 with adhesive tape or the like. Then, the outer periphery is wrapped in one or several places with an outer circumferential band such as a wire, and the coil transfer device 2 is operated again to transfer the packed coil 6 on the saddle 10 to the first
Move it further to the right in the figure and carry it to the specified location. Thereafter, the packed coil 6 is unloaded and the saddle 10 is returned to its original position, completing one cycle.

[Effect of the invention] As described above, in the present invention, the structure is as described in the claims for utility model registration, and the coil is loaded onto the saddle of the coil transfer device by the operation of the coil lifting and transfer device. Before starting the process, a part of the packaging material installed in the coil transfer equipment line was placed on top of the saddle, allowing the saddle and coil to move sideways. Coils can be reliably and easily packaged in a series of operations on the same line. And there is no danger in the packaging process. In addition, by setting the packaging material under the coil on the saddle, there is no need to install a lifter device for lifting the coil in the coil transfer device as in the past.
Extremely useful.

Furthermore, in the present invention, packing materials such as roll-shaped packing paper, which are generally available on the market, are set in a supply feeder, and a transfer device with a saddle, which is originally provided for the purpose of transferring coils, is used. Then, the packaging material can be pulled out from the supply feeder in an amount corresponding to the outer circumferential length of the coil and cut with a cutter built in the supply feeder. Therefore, even if the outer diameter of the coil changes, there is no need to prepare packaging materials cut in advance to various lengths depending on the outer circumference of the coil. The packaging material can be supplied wrapped around the outer circumferential surface of the coil, making it easy to work and economical. In addition, when the saddle carrying the coil is transferred laterally, the saddle is transferred from one side to the other under the supply feeder, so as the saddle is transferred, half of the packing material is naturally spread on the outer circumferential surface of the coil. The ends of the packaging material that have been wrapped around the coil and cut to the desired length with a cutter will naturally hang from top to bottom on the outer circumferential surface of the coil, so the ends of the packaging material that have gone around the coil will The large diameter coils can be easily attached to each other with duct tape at the bottom, making it extremely easy to work with.

Furthermore, according to the present invention, when packing a large coil with a diameter of 2.6 m, the packing work, which previously required three people, can now be carried out reliably and easily by one person.

In addition, in this invention, the coil is not rolled, but placed on a saddle that can be moved horizontally, and then packed while being moved horizontally in that position, so that the coil does not come undone or gets damaged. No problem, packaging is done well and reliably and easily.

In the present invention, as a feeder for supplying packaging materials, a holder for packaging materials, a feed roll consisting of a set of two rotatable rolls with adjustable pressing force, and two rolls that become narrower toward the bottom. A guide plate, a cutter for cutting packaging material installed in the narrow part of the guide plate, and a cutter whose lower end expands toward both the front and rear sides of the saddle in the direction of movement of the saddle, below the entrance and exit part of the cutter. Since a structure consisting of two guide plates is used, operations such as feeding and cutting of packing materials can be performed reliably and easily. Furthermore, the lower end of the guide plate below where the packaging material comes out expands toward both the front and rear sides, so no matter where the coil is placed, it will not damage the packaging material. Packing materials can be sent out smoothly without any problems.

In addition, since the present invention is designed to package coils using a device such as that described in the scope of the utility model registration claims, an existing steel strip coil conveying device for steel manufacturing is used to package the coils as part of the conveying equipment. It is possible to install a feeder for supplying packaging materials and use the equipment originally intended for conveyance. In other words, this device:
Since it can be installed using a portion of existing transport equipment, the equipment is simple, takes up little space, and does not require much additional operation.

Note that coils are transported in different widths due to their properties and uses. That is, the width of the produced coil changes variously on an hourly basis depending on demand. Therefore, a plurality of rolls are provided in the feeder for supplying the packaging material, and the rolls are unwound as appropriate, so that it is possible to easily accommodate several types of coils having different widths.
