DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for automatically forming and inserting an inner peripheral iron plate into an inner diameter portion of a steel coil when packing a steel coil such as a lomo coil.

[0002]

2. Description of the Related Art A relatively soft steel coil such as a lomo coil used as an original tin plate is used to prevent deformation and damage during transportation, or to prevent rust and moisture in a packing process after manufacturing. The face and both end faces may be packed without gaps. In this packing operation, after covering the outer peripheral surface and both end surfaces of the steel sheet coil with paper and further an iron plate, as shown in FIG. 9, inserting a cylindrical inner peripheral iron plate into the inner diameter portion of the steel plate coil,
This is completed by fitting inner diameter rings on the inner diameter sides of both ends of the inner iron plate, and further hooping the entire steel coil with a plurality of steel bands (not shown).

[0003]

Since the conventional packing work is all manual work, the work efficiency is low. In particular, in order to form the inner iron plate and insert it into the inner diameter of the steel coil, it is necessary to temporarily hold the inner iron plate in a slightly reduced state before insertion to facilitate insertion. It was performed by temporarily fixing the beginning and end of the iron plate to each other with adhesive tape, etc., but this work is difficult, and the inner peripheral iron plate forming process → adhesive tape attaching process → inner peripheral iron plate inserting process In addition, carrying the inner peripheral steel plate between each process is also a manual operation, which is not efficient in spite of labor.

[0004] It is an object of the present invention to implement an inner peripheral iron plate forming / inserting apparatus which can completely automate a series of steps from forming to insertion of the inner peripheral iron plate.

[0005]

According to the present invention, in order to solve the above-mentioned problems, a bogie that can move back and forth in the axial direction of the steel coil is disposed at a lateral position of the horizontal steel coil.
Eccentricity slightly lower than the center height of the inner diameter of the steel coil
A winding shaft that can be inserted and rotated at a position is provided . The winding shaft is formed by winding and forming a steel sheet for the inner peripheral iron sheet supplied from the steel sheet supply device into a cylindrical shape with the overlapped portion facing downward, and a stop for holding the formed inner peripheral iron sheet in a wound state. Equipped with nails. Furthermore, in order to complete the airtightness of the packing of the steel sheet coil, a sponge tape attaching machine for attaching sponge tape to both sides of the steel sheet sent by the steel sheet supply device can be provided.

[0006]

[Action] The inner iron plate formed by being wound around a winding shaft is inserted into the inner diameter portion of the steel sheet coil in the wound state, and then the fastening claws are opened, so that the inner iron plate becomes its own spring. It is elastically attached to the inner peripheral surface of the inner diameter part by the back action. The sponge tape adhered to both ends of the outer peripheral surface of the inner peripheral iron plate is in close contact with the inner peripheral surfaces of both ends of the inner diameter portion.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Before explaining an inner ring mounting apparatus according to an embodiment of the present invention, a packing process of a steel sheet coil will be described.

FIGS. 9 to 11 show the first stage (basic packing) of the packing process, FIGS. 12 to 14 show the second stage (preferred packing) of the packing process, and FIG. Figure 2 shows the stage of completion of the most suitable package completely protected against mechanical shock.

FIG. 9 shows the first step of the packing step. The steel sheet coil C is wound to form an inner diameter part, and the outer end is tape T
Stopped at. The steel sheet coil C must protect not only the outer peripheral surface but also the end surface E and the inner peripheral surface of the inner diameter portion O from moisture and mechanical shock, and particularly protects the outer peripheral edge Go and the inner peripheral edge Gi from damage. Must.

An end surface contact soft board 1 having a special configuration is prepared for enclosing the end surface E. This soft board 1
In the central hole 3 of the annular disk portion 2, an insertion cylindrical portion 4 for inserting into the inner diameter portion of the coil is fixed to a flange portion 5 thereof. Both the circular disk portion 2 and the cylindrical portion 4 have a thickness of 4 to 5
It is preferably formed from a millimeter polyethylene laminated sheet, particularly a sheet having a surface coated with a vaporizable rust inhibitor (VCI). One such end-face contact soft board 1 is mounted on each side of the coil end face.

A steel sheet coil C whose end face is covered and protected.
Next, for example, a mandrel is inserted into the inner diameter portion thereof and suspended in the air, and the outer peripheral paper 10 is wound thereon as shown in FIG. If the coil is a high-grade product such as a lomo coil,
Rotating the coil while laying it sideways may damage the product. Therefore, the packaging material must be wrapped around the suspended coil. The outer peripheral paper 10 is wound so that both side edges 11 protrude slightly from the end face.
The outer peripheral paper may be wound so as to have a length just around the coil. Such winding can be performed by an automated operation. The longitudinal edges join or overlap or abut each other. Preferably, the outer peripheral paper 10 has the same V
It can be formed from CI coated polyethylene laminate base paper.

Next, as shown in FIG. 11, both side edges 11 of the outer peripheral paper 10 are gathered and folded 12 on the soft disk annular disk portion 2 on the end face, and are bonded with a suitable adhesive, for example, a hot melt. Complete basic packaging. Gathering is automated using a well-known chrysanthemum blade. In this state, the outer periphery of the steel sheet coil is formed by the outer peripheral paper 10 and the inner periphery is the insertion cylindrical portion 4.
The end face is completely covered by the annular disk portion 2 of the soft board 1, and the outer and inner peripheral edges are covered and protected.
Unless there are strict requirements, steel coils can also be shipped in this basic packaging.

In the case of an object to be packaged which requires a high degree of protection against mechanical damage, such as the above-mentioned lomocoil, etc., it is possible to further completely reduce the size of the package shown in FIGS. It is desirable to pack up to the shape of.

The first step of the preferred packaging involves winding the outer peripheral board 18 by an automated operation, as shown in FIG. The outer peripheral board 18 has a thickness of about 2 to 3 mm and a coil width W.

The winding of the outer thin iron plate 20 can be performed automatically or semi-automatically. As a result, the outer peripheral surface of the lomo-coil is formed on the outer peripheral paper 10 (FIG. 11) and the outer peripheral board 18 (1).
3) and the three layers of the outer thin iron plate 20 so that the moisture-proof, rust-proof and impact resistance are perfect.

For the purpose of holding down the outer thin iron plate 20 or preventing gaps on both sides, and for more complete protection of the outer edge of the coil,
As shown in FIG. 14, the edge tape 22 is wound around both side edges. The edge tape 22 is preferably a foamed polyethylene tape having a thickness of about 5 mm, and preferably has a firing rate of about 30 to 40 times.

Thus, the steel sheet coil having the appearance as shown in FIG. 14 can be shipped. Since the outer peripheral surface is covered with the thin iron plate 20, it is protected from damage due to piercing and the like, and the end surface is also protected by the internal soft board 1 and the end surface board 14 thereon, so that it is mechanically damaged. Nothing. And since both edges are protected by the edge tape and the coil is pressed firmly so that the winding of the coil does not loosen, there is no loosening or rubbing between layers even if the coil is rolled anymore, There is no risk of quality loss.

However, if more advanced and more complete protection is desired, as shown in FIG.
