Description

  The present invention relates to an apparatus for wrapping a coil in which a steel sheet is wound in the form of a winding paper with a protective sheet. The present invention also relates to a metal coil protective sheet packaging apparatus that can be carried out easily and can obtain excellent packaging quality.

  Generally, cold-fired coil products such as electrical steel sheets, automotive steel sheets or plated steel sheets produced in the cold-burning process through various processes in steel mills are produced through surface treatment, so In order to prevent the surface of the coil product from being damaged during transportation and storage, the outer surface of the coil is wrapped with a protective sheet and packaged.

  That is, the method of wrapping a metal coil continuously produced on a production line is to wrap the protective sheet while rotating the coil product to be wrapped, or to lay the protective sheet after lifting the coil product to be wrapped Primitive packaging method is adopted in which the coil product is lowered again and manually packed by the operator.

  Here, the conventional method of packaging coil products by a mechanical method is to first cut a protective sheet with a cutter to a certain length while uncoiling the protective sheet coil on which the protective sheet for packaging is wound. Prepare.

  The packaging operator draws out the material having the width of the approximate value from the protective sheet cut to fit the width and outer diameter of the coil product to be wrapped, that is, the coil in the form of a winding paper, and the protective sheet Cuts the side surface of the protective sheet so that the width of the coil product to be packaged by the manual cutter and the width of the protective sheet coincide.

  Subsequently, the front and rear of the plurality of protective sheets are formed so that the side-cut protective sheet has a length that can cover the outer diameter length (circumferential length) of the coil to be wrapped. A series of protective sheets are formed by overlapping and connecting the rear ends, and the coil product is used for packaging.

  The protective sheets connected as described above are mounted by a driving roller that is rotated by two workers after being manually attached to the coil directly using vinyl tape, or after the coil is seated on the driving roller. While rotating the coil, it is attached to the coil product by pasting it into the prepared protective sheet and packaging.

  However, during such conventional packaging operations, if traces of glue remain on the coil product or scratches occur on the expensive thin steel plate product, the post-processing operation to remove this is considerably troublesome and the generation of scratches is serious. If this is the case, the quality of the steel sheet will be damaged.

  Also, since the protective material is wrapped while the coil product is rotated by the rotational force of the driving roller, if the left and right diameters of the coil are different from each other, the coil product is naturally tilted to the left and right when rotating. As the current situation arises, good quality packaging becomes difficult.

  Until now, such conventional methods cannot keep up with the output speed of continuously produced coils, or various industrial disasters when workers manually handle heavy coil products. To act as a factor.

  Such a traction member (222) is provided along the circumference of the original traction chute (220) so that the inner surfaces of both end portions of the protective sheet (2) are in contact with each other, and a chain is attached to the outer surface. The chain meshes with a prototype gear (228) provided on the drive shaft of the traction motor (226). At this time, the prototype gear (228) is provided so as to be pulled into the prototype traction chute (220) through a groove (not shown) formed in a certain length so as to mesh with the chain.

  The traction member (222) configured as described above travels along the circumference of the original traction chute (220) while pulling both end portions of the protective sheet (2) by the driving force of the traction motor (226). By doing so, the protective sheet (2) is wound into a cylindrical shape.

  Further, the present invention provides a vacuum suction device (260) provided between the original tow chutes (220) disposed on both sides of the guide chute (210) and configured to adsorb the protective sheet (2). Further included.

  The vacuum suction machine (260) is configured such that when the two prototype traction chutes (220) are separated from each other by the chute moving motor (221), the cylindrical protective sheet (2) is separated from the prototype traction chute (220). The protective sheet (2) is prevented from falling down by adsorbing the protective sheet (2).

  With the protective sheet (2) wrapped around the coil (1) product in this way, the plastic band (270) is pulled out through the band moving passage (274) and has the same circumference as the original tow chute (220). The protective sheet (2) is wound by the length, and when such winding is completed, the rewinding is advanced by the head of the binding machine (272). Due to the rewinding action, the protective sheet 260 is brought into close contact with the coil product and bound.

  In addition, when the unwinding reaches a considerable tensile force, the plastic band (270) is welded and attached by the heat generating device in the binding machine head, and the protective sheet ( Installation of 2) is completed. Here, as the binding machine, a conventionally used binding machine is adopted and utilized.

  On the other hand, since the same reference numerals as those shown in FIG. 1 to FIG. 9 correspond to the same components, description thereof will be omitted.
