Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sheet folding device for automatic packing of wire rod coils.

[0002]

2. Description of the Related Art Conventionally, a wire wound in a coil is
After hot rolling, it is stored as it is in a warehouse or stockroom and shipped from there to customers.However, wire rod coils that have been bound, weighed, etc. have scratches or the like due to contact between the coils. Since it is in an easy state, wire flaws at the time of loading and unloading, product contact at the time of stacking, at the time of transportation and stacking in the factory, at the time of shipping from the factory by sea, by sea, by freight car or by car Defects, scratches, etc. occur. Particularly in recent years, surface defects during transportation have come to be regarded as a problem along with the sophistication of products, and for that reason, packaging has been required.

However, as a conventional method of packing a wire rod coil, as disclosed in Japanese Patent Publication No. 62-18427, a rectangular synthetic fiber cloth is used with a fastener and a string or a rope. The outer circumference and end surface of the wire rod coil by fastening both ends of the packing cloth with fasteners and squeezing and binding the drawstrings or loops on both open end sides of the wire rod coil. It is a method of coating. Further, the method disclosed in Japanese Patent Laid-Open No. 52-90382 relates to an improvement of a packing device for performing a gate winding in which a strip-shaped packing material such as rust-proof paper is sequentially shifted and wound around a material to be packed such as a wire coil. Therefore, when there is no band-shaped packing material in use, or when different kinds of band-shaped packing materials have to be used, the packing apparatus is designed to be able to immediately perform the packing work following the conventional packing work.

[0004]

As described above, as a conventional wire rod coil protecting means, there is disclosed in Japanese Unexamined Patent Application Publication No. Sho 62-62.
As in the method disclosed in Japanese Patent No. 18427, a synthetic fiber must be prepared according to the size of each wire rod coil before packing, and this cloth can be attached to a fastener and a string or a rope. Since the outer peripheral surface of the coil is a method of covering the end surface, the work must be done manually, and
It is hard to say that the coating itself is strong, the coating of the inner peripheral surface of the wire rod coil cannot be done, and the packing work speed of the wire rod is slower than the binding work speed of the bundled wire rod. There is a problem that it is impossible to carry out work continuously. Further, although it has been automated by the packing by the gate winding method in which the band-shaped packing material disclosed in Japanese Patent Laid-Open No. 52-90382 is sequentially shifted and wound, the band-shaped shape serves as a buffer for the inner and outer surfaces and end surfaces of the wire coil. However, from the viewpoint of preventing moisture such as intrusion of rainwater during transportation and preventing rust, there is a problem that the seal at the joint of the band-shaped packaging material cannot be perfect.

[0005]

The present invention is to solve the above-mentioned problems of the prior art. As a result of the inventors' earnest efforts, the packing sheet has a rectangular minimum necessary area.
In addition, it does not require pre-processing and enables automatic packing as it is. The gist of the invention is that the protruding members, which are located at both ends of the wire coil and are wound around the packing sheet, are converged toward the center by slide bars arranged so as to be able to stand by in the outer peripheral direction, and the packing carriage is moved forward. Thus, the wire sheet coil automatic packing sheet folding apparatus is characterized in that the packing sheet is folded into the inner diameter portion of the wire rod coil.

[0006]

The present invention will be described in detail below with reference to the drawings. FIG. 1 is an overall conceptual view of a slide bar according to the present invention standing by at the rear portion of a wire rod coil, and FIG. 2 shows a state in which a packing sheet in an apparatus according to the present invention is folded into an inner diameter portion of the wire rod coil. It is a figure. As shown in FIG. 1, the wire rod coil 1 is placed on the pair of cradle rolls 2 and
By rotating the cradle roll 2 by the drool roll driving device 2A and rotating the wire rod coil 1, the packing sheet S is entirely configured to be wound in the circumferential direction of the wire rod coil 1. There is.

FIG. 3 is an overall plan view of the device according to the present invention. The operation of the device of the present invention will be described in more detail with reference to FIG. As shown in FIG. 3, a coil carriage 5 having a pair of cradle rolls 2 capable of rotating with the wire rod coil 1 mounted and a drive unit 2A for the cradle roll 1 is provided in the axial direction (width direction) of the wire rod coil 1. Arranged so that it can move to the side intersecting with,
The packing carriage 4 is arranged so as to be able to move forward and backward on both sides in the axial direction of the wire rod coil by sandwiching the coil carriage 5, and the coil carriage 5 is sandwiched within the moving range of the coil carriage 5, and the front surface of the packing carriage 4 is located on both sides thereof, that is, When the coil carriage 5 is at the original position, the sheet feeding device 6 is arranged at the position which is the front surface thereof. Each of the two packing carts 4 provided has a slide bar-3 which can be opened and closed at the same time on the front surface thereof. This slide bar
3, the projecting members on both end surfaces of the coil are slid in the central direction to focus the packing sheet S, the packing carriage 4 is moved forward, and the projecting member is folded into the coil inner diameter portion.

[0008] Thus, the sheet coil packing sheet folding device is provided on both sides of the wire coil, and the protruding member after winding the packing sheet is surely converged by the slide bar and moved forward to advance the coil inner diameter portion. It was possible to automate the insertion into the. Moreover, by making the slide bar a parallel focusing type, it is possible to make the sheet focusing reliable, and further, by determining the focusing diameter according to the coil inner diameter corresponding to the variation of the coil inner diameter portion, This will improve the packing appearance after folding.

EXAMPLE A wire rod coil 1 is placed on a cradle roll 2 and the cradle roll 2 is rotated to rotate the wire rod coil 1, whereby the packing sheet S is turned into a wire rod coil. 1 is wound in the circumferential direction. The packing sheet S is made by stacking two kinds of materials, that is, a cushioning cloth and a moisture-proof laminate paper, and is prepared so that the laminate paper is the surface when wound around the wire coil 1. There is. Next, by rotating the cradle roll 2, the wire rod coil 1 is rotated, and in synchronization with the rotation speed of the wire rod coil 1, the packing sheet S is attached to the packing sheet S by a rotating gripping member (not shown). Coil 1
And the cradle roll 2 are sandwiched between the wire rod coil 1 and the wire rod coil 1. During this period, the rear end of the packing sheet S is detected, the rotation of the wire rod coil 1 is stopped, and a bonding material such as an adhesive tape is attached to the rear end of the packing sheet.

After that, the cradle roll 2 is further rotated and the wire rod coil 1 is rotated once. After that, in order to join the beginning and the end of the packing sheet S with a joining material attached in advance, a sheet is attached. A press-bonding device (not shown) is pressed against the packing sheet fixing member. At this time, it is not necessary to crimp the portion of the wire rod coil 1 again because the joining portion at the start and end is crimped by the weight of the wire rod coil 1 when it is rotated by the cradle roll 2. The wire rod coil 1 with the packing sheet wound around is left mounted on the cradle roll 2, and the sheet protruding members at both ends are slidably attached to the slide bar-3.
Are bundled by sliding in the central direction, the packing carriage 4 is moved forward, the protruding member is pushed into the inner surface of the coil, and the inner, outer surface and end surface of the wire coil 1 are packed.
