Definitions

  • the present invention relates to a rolled base paper web feeder as defined by the features of the preamble of claim 1 and adapted to be equipped in a corrugating machine, a rotary press or the like.
  • Fig. 3 is a schematic view illustrating a method for exchanging base paper webs according to an order change
  • Fig. 4 is a schematic view to be referred to for illustrating disadvantages of the base paper web feeder in the prior art.
  • base paper webs (a liner, a core paper web) 1a and 1b for manufacturing corrugated cardboard sheets are formed in a roll shape, and under an initial setting condition, they are carried in and installed at predetermined positions within a manufacturing line with the opposite ends of their central portions supported by rolling centers 3 of base paper web feeders Pa and Pb.
  • these base paper webs 1a and 1b to be used for the manufacture are successively payed out by pinching rotation of feed rolls 16a and 16b to be conveyed to the next step of the process, and in order to prevent occurrence of creases and slackening by braking excessive feed and applying a back tension, at the rolling center portions 3 of the base paper web feeders Pa and Pb are provided brakes not shown in the figure.
  • a leading end of a new-order base paper web 1b held in a standby state is joined to a traveling old-order base paper web 1a via a double-sided adhesive tape 17, and also the old-order base paper web 1a is cut at the position Z shown in the figure by means of a cutter 18 disposed contiguously to this joining point so that the next new-order base paper web 1b can be fed continuously.
  • a base paper web portion X-Y-Z as shown in the figure that is, a leading end portion of the paper web corresponding to the length from a position X where the rolled base paper web 1a is payed out up to a cutting position Z would be left under a pulled-out condition.
  • the above-mentioned paper web end rewinding apparatus in the prior art did not have an automatic setting function for the paper web end position, and so, depending upon a stop position of the paper web end after it was wound around the roll, there was a disadvantage that the paper web end may loosen and sag as illustrated in Fig. 3, or it may stop at a location where a workability is bad, resulting in inconvenience for the sticking work of the anti-slackening tapes 19. Therefore, in view of these circumstances, upon positioning of the leading end of the paper web, delicate handworks (rewinding around the roll) or fine movements in the case of a motor-drive type of apparatus were necessitated. Accordingly, a long time was necessitated as a working time period and the work was difficult, and hence a working efficiency could not be improved, and this became a large problem jointly with frequent order changes.
  • a prior art base paper web feeder is described in JP-A-57-121549.
  • This known feeder has a shaft supporting a roll of a base paper web, a revolution number detector equipped on the shaft to obtain its revolution number, a speed detector in touch with the base paper web and a controller for determining a remained length of base paper web on the roll based on this information for inventory purposes.
  • a more specific aspect of the present invention is to provide a base paper web feeder, in which upon exchange of base paper webs, feeding of an old-order base paper web is stopped with a leading end cut portion of the old-order base paper web placed at a predetermined position on the circumference of the original old-order rolled base paper web, and adhesive tapes for fixing can be sticked automatically.
  • a base paper web feeder comprising a rolling center for supporting a roll of a base paper web, a revolution number detecting means for detecting a revolution number of the rolling center, a traveling velocity detecting means for detecting a traveling velocity of the base paper web, and a controller to which the revolution number detecting means and the traveling velocity detecting means are connected, characterized in that a rotary driving device is provided for the rolling center, said controller is adapted to calculate data corresponding to an amount of revolution of said rolling center on the basis of a relation between a length between a predetermined position of the leading end of the base paper web on the circumference of the roll and a cut position of the base paper web and a diameter of the base paper web roll determined from the revolution number of the rolling center and the traveling velocity, wherein said calculated data is fed back from the controller to the rotary driving device so as to rewind a payed out length of the base paper web onto the roll.
  • the above-mentioned number of revolution N0 is fed back to a rotary driving device of the rolling center (rolled old-order base paper web), the roll of the base paper web is inversely rotated by this number of revolution N0, and thereby the leading end portion of the old-order base paper web cut for the purpose of exchange of base paper webs is rewound on the roll.
  • the present invention owing to the above-mentioned control, it becomes possible that, after the cut portion of the leading end of the old-order base paper web has been set (stopped) at a predetermined position on the circumference of the rolled base paper web, adhesion tapes for anti-slackening are automatically stuck, and therefore, exchange of base paper webs necessitates only the works of unloading an old-order base paper web and loading a new-order base paper web.
  • Fig. 1 is a general view of construction for explaining a base paper web feeder according to the present invention.
  • a remaining leading end portion rewound (payed-out) from an old-order base paper web is wound on the side of the original roll, and a leading end cut portion is allowed to stop at a predetermined position on the circumference of the roll, so as to automate following treatments such as prevention of slackening and the like, that is application of tapes for fixing, the construction and function of which will be explained hereinafter.
  • brakes 4 at rear ends of a pair of rolling centers 3a and 3b supported by movable stands 2 with a shaft at the base paper web feeder portion in order to support a known rolled paper web 1.
  • the brake 4 is constituted by a rotational element 4b secured to the shaft of the rolling centers 3a and 3b via a key 5 and a rotational element 4a, in which a gear 6 secured to one end side of the rotational element 4a is engaged with a gear 8 secured to an axial end of a motor 7 mounted to the same stand 2.
  • an encoder 10 to an axial rear end of the rolling center 3a at one side is mounted an encoder 10 via a coupling 9.
  • an encoder 14 via a coupling 13 in the same manner as the rolling center 3a.
  • 15 is a controller in which after input of data transmitted from the encoders 10 and 14 for calculation, the feed back to the motor 7 is performed, and thereby a number of revolution (angle) of the rolling center 3 (rolled paper web 1) can be set.
  • the rolled paper web length L payed-out at the leading end of the rolled paper web upon joining the paper web that is a length between the standard point X on the circumference of the rolled paper web, the point Y for turning around the guide roll 12 and the cutting point Z of the base paper web in Fig. 2 is approximately a constant value.
  • the working place shown in Fig. 5 (the position Y for sticking the anti-slackening tapes) can be optionally set by correction with respect to the standard point X, and also excessive rotation or the like of the rolled paper web accompanied by the inertia after cutting can be easily corrected by counting the number of revolution with the encoder 10 to be inversely rotated.
  • the present invention is constructed to provide the function as described above, wherein the position Z of the cutting point (the utmost leading end portion) of the old-order base paper web cut for the purpose of exchange of base paper webs is subjected to winding to the side of the original roll to make it possible to be positioned at the specified place on the circumference.
  • 20 in Fig. 2 is a tape sticking device constructed as a pair to be capable of contact and separation with respect to the outer peripheral surface of the rolled paper web or as plural sets provided to align in an axial direction of the roll of the rolled paper web, with which after the rolled paper web is wound to the side of the roll to allow the leading end to stop at a predetermined position, for example, at X, the anti-slackening tapes 19 can be automatically stuck at the specified positions shown in Fig. 7 (three positions in the figure).
  • the above mentioned automatic tape sticking device there are various known types.
  • the treatment of the leading end of the old-order base paper web is automated, so that the exchange of base paper webs necessitates replacement of new-order and old-order base paper webs only.
