BACKGROUND OF THE INVENTION
The present invention relates to a bundling apparatus for a coiled article that can supply and bind end plates for protecting end faces of both ends of the coiled article when bundling the coiled article.
[0002]
[Background Art and Problems to be Solved by the Invention]
Conventionally, a strap made of metal or resin is used by a bundling device to convey or store an article (coiled article) in which a wire or a metal thin plate or paper is wound in a coil shape while maintaining its form. In a band, a plurality of portions in the circumferential direction of the coiled article are generally bundled so as to go around the outer periphery from the inner cylinder of the coiled article (so-called “vertical winding”). It is. In this case, in order to prevent scratching at both ends of the coiled article during transportation or the like, the straps with the end plates made of cardboard or resin are disposed at both ends (or one end). Can be united. As described above, this end plate has a donut-shaped (annular) shape whose center is opened in accordance with the inner cylindrical portion of the coil so that the strap can pass through when bound by the strap.
[0003]
Conventionally, the coil-shaped article is suspended and conveyed by a suspension means called a “C hook (C-shaped hook)” from the final manufacturing location to the binding device, and manually before binding. End plates were arranged in advance at both ends, and then wrapped with a binding device.
[0004]
However, binding is generally performed automatically. However, placing this end panel before binding by hand only requires one person at both ends when the end panel is only one end, despite the small amount of work. In order to arrange the end plate, two workers were required, which was extremely irrational. Moreover, since it is necessary to consider the safety of workers when working manually, idle time (dead time) occurs before and after the manual work process during the bundling work cycle, and the time cycle of the bundling work cycle is reduced. It becomes a factor to lengthen.
[0005]
The present invention has been made in view of such a current situation, and provides an end plate supply set device for a coiled article, in which the end plate can be automatically arranged and bound on the end surface of the coiled article in the binding device. The purpose is to do.

The second end plate holding member is configured to hold the end plate and operate in the close state through the retracted state so that the end plate is brought into contact with the second end surface and is bound in the abutted state. And
[0011]
Thus, according to the bundling device configured as described above, a donut-shaped end plate is supplied to the distal end portion of the first end plate holding member by a robot or the like prior to binding, and the second end plate holding is performed. If a donut-shaped end plate with a part of the ring cut to the member (corresponding to the width of the member holding the C hook) is supplied by a robot or the like, the tip of the band chute of the bundling device However, the end plate is disposed so as to come into contact with the first end face of the coiled article at the end of entering the inner cylinder of the coiled article held by the C hook. In addition, when the tip of the band chute of the bundling device has been completely inserted into the inner cylinder of the coiled article held by the C hook, or in the final stage, the second end plate holding member is turned into the coiled article. On the other hand, an operation of approaching from the retracted state is performed, and the end plate is also arranged on the second end face of the coiled article. At this time, by forming the end plate held by the second end plate holding member into a donut shape in which an annular part is cut, the cut portion may pass through the C hook portion with respect to the C hook. Even in a state where the coiled article is suspended from the C hook, the end plate can be disposed on the second end surface without interfering with the C hook.
