Definitions

  • the present invention relates to a slitterscorer provided with a shear unit which is operated upon order change and which can for a plurality of notches (slots) along a widthwise direction of a continuously traveling corrugated cardboard sheet.
  • a rotary shear is an apparatus acting upon a corrugated cardboard sheet manufactured continuously in a corrugating machine at the preceding step for cutting it in the widthwise direction or notching it along the widthwise direction, and it operates upon order change and can function to deal with change of setting in response to variations of a specification such as width change of trims 16, width change of produced sheets 2 and the like.
  • FIG. 6 is a perspective view showing an operating state of a rotary shear, in which an engaging condition between an anvil 20 on a circumferential surface of an anvil cylinder 17 and a cutting knife 19 of a knife cylinder 18 and a working condition upon a traveling corrugated cardboard sheet 1 are illustrated, and the knife cylinder 18 having the knife 19 fixedly secured thereto is pivotably supported at its opposite ends via bearings not shown from frames provided upright at the both ends of the width of the apparatus.
  • an anvil cylinder 17 disposed in opposition to the above-mentioned knife cylinder 18 is also pivotably supported at its opposite ends via bearings from the same frames.
  • the anvil cylinder 17 is coupled to the above-described knife cylinder 18 via corresponding gears so that they can be rotated in the opposite directions as synchronized with each other, and a corrugated cardboard sheet 1 travels through a gap between the anvil cylinder 17 and the knife cylinder 18 while being kept in rolling contact with the anvil cylinder 17.
  • the anvil (elastic body) 20 is partly removed so that its central portion may be gradually reduced in width from a total width l up to a predetermined dimension l o , and thereby a step (unevenness) is formed. Therefore, by variably setting a relative phase of the anvil cylinder 17 engaged with the knife 19 on the knife cylinder 18, various modes of cutting and machining as shown in Fig. 8 can be carried out.
  • the rotary shear of the aforementioned type can machine notches having any arbitrary length from zero to the maximum length of (W-l o )/2 at the both width ends of the corrugated cardboard sheet 1 by appropriately variably setting the position B where the anvil 20 is engaged with the knife 19.
  • the anvil cylinder 17 is rotated by driving a motor for indexing, and thereby a relative phase of the anvil cylinder 17 with respect to the knife 19 corresponding to a desired cutting or machining condition for the corrugated cardboard sheet 1 is adjusted and maintained. Subsequently, an electromagnetic clutch not shown is operated, and by intermittently transmitting power from a line shaft at a predetermined timing, notching or cutting for the traveling corrugated cardboard sheet 1 is carried out.
  • Fig. 9 illustrates a machined condition of a corrugated cardboard sheet so as to correspond in position to the state shown in Fig. 10.
  • Slitterscorers Pa and Pb are apparatuses for applying predetermined ruled lines K and slitting slots S to a traveling corrugated cardboard sheet 1 as shown in Fig. 9 by means of provided ruled line rolls 21a and 21b and slitter knives 22a and 22b, and in relation to a necessary product sheet width W o , by appropriately selecting the corrugated cardboard sheet width W, it is possible to carry out simultaneous production of a plurality of sheet (multi-sheet production) (Fig. 9 illustrates the case of two-sheet production).
  • New trim positions accompanying the order change are transmitted as signals from an order change system controller not shown, in the slitterscorer Pb under a standby condition, besides setting in position of the trim duct 23b, various setting corresponding to the new order is effected, at the same time in a trim cutting device (rotary shear), in order to set cut amounts at the both width ends of the corrugated cardboard web corresponding to the new order, a relative phase angle of the anvil cylinder 17 is set with respect to the position of the knife 19.
  • a trim cutting device rotary shear
  • the knife cylinder 18 and the anvil cylinder 17 are rotated in the opposite directions at a predetermined timing for allowing the corrugated cardboard sheet 1 to pass therebetween, and trim cutting and notching are effected at desired positions.
  • the above-mentioned notched position is transferred to the slitterscorer Pb in a standby state, then at a predetermined position at first the ruled line rolls 21b are engaged with the corrugated cardboard sheet 1, subsequently the slitter knives 22b are engaged therewith, and successively machining is effected according to the new order.
  • the rotor shear in the prior art had only two kinds of capabilities of forming notches of arbitrary lengths at the both width ends of a traveling corrugated cardboard web and perfectly cutting the web over its entire width, and accordingly under the setting of two-sheet production as shown in Fig. 9, as a result of order change, only the width of the trims 16 at the ends of the width is changed.
  • a specification could be changed stably only under a limited condition such that a slitting slot for separation at the center of a sheet is continuous, in the case where even if the above-mentioned slitting slot for separation of a sheet should become discontinuous as a result of change of a production sheet width, cut lengths of the two sheets traveling in parallel are the same, or in the case where only one kind of production sheets 2 are produced from one corrugated cardboard sheet 1 not shown.
  • a discontinuous portion X would remain at the central slitting slot, hence upon change of traveling routes (separation into upper and lower routes) in a cut-off step of the process at the downstream which is effected in the case where the sheet lengths of the sheets traveling in parallel are different as described above, not only the aforementioned discontinuous portion would be broken and would become unacceptable product sheets, but also the broken sheet pieces would be caught by conveyor means (feed rolls) at the downstream, and so, troubles such as jam-up would arise frequently.
  • the rotary shear in the prior art had only two kinds of capabilities of forming notches of arbitrary lengths in the widthwise direction of a sheet at the both width ends of a corrugated cardboard sheet and perfectly cutting the sheet over its entire width. Accordingly, although the rotary shear can smoothly deal with (switch) by means of notches formed at the both width ends under an extremely limited condition as in the case where only trim widths are changed according to order change, upon multi-sheet production in which a plurality of kinds, two kinds for instance, of sheets having different widths are produced from a single corrugated cardboard web, in the case where the widths of the sheets are changed according to order change and the cut sheet lengths are different, at the changing point of the new and old orders, a slitting position would shift in the widthwise direction, resulting in a discontinuous portion, hence there was a disadvantage that the sheets would be broken by separation of the sheet traveling routes at the cut-off in the next step of the process and the sheets would become unacceptable product sheets.
  • a slitterscorer in a corrugating machine for carrying out cutting and scoring of a continuously traveling corrugated cardboard sheet along the traveling direction of the sheet, in which the slitterscorer comprises a shear unit for forming notches (slots) at a plurality of locations along the widthwise direction of the continuously traveling corrugated cardboard sheet, whereby the problems involved in the heretoknown slitterscorer can be resolved.
  • the present invention owing to the above-mentioned structural feature, in the case where trim width dimensions at the opposite side edge of the sheet are changed according to order change, or in the case where sheet widths are varied during multi-sheet production in which a plurality of kinds of sheets having different lengths are produced, since it is possible to machine and form notches directed in the widthwise direction of the sheet only at the portions where the notches are necessitated, the disadvantage such that the sheet is broken at the change point of a specification would be eliminated, even if the new and old sheets are not perfectly separated according to order change as is the case with the method in the prior art. Accordingly, the sheets can be conveyed stably, a precision in cutting dimensions can be maintained accurate, and also troubles such as jam-up or the like can be eliminated.
  • FIG. 1 to 4 A slitterscorer provided in a corrugating machine according to one preferred embodiment is illustrated in Figs. 1 to 4.
  • the functions of a slitterscorer P for carrying out cutting and scoring for a continuously traveling corrugated cardboard sheet 1 along the traveling direction of the sheet, are similar to those of the above-described slitterscorer in the prior art.
  • the present invention can achieve a larger effect in function in the case of multi-sheet production where two or more product sheets 2 are produced in parallel from a single corrugated cardboard sheet 1 by providing a shear unit which can form notches (slots) at a plurality of locations along the widthwise location of a traveling corrugated cardboard sheet 1 in the above-described slitterscorer, and the invention is characterized in that even in the case where a width W o of a product sheet 2 and/or a cut length L of the sheet are changed according to order change, the sheet can be stably transferred to the next step of the process in a continuous state as a whole by forming notches directed in the widthwise direction only at necessary portions without perfectly cutting and separating the sheet 1 as is the case with the slitterscorer in the prior art.
  • Figs. 1 and 2 illustrate a structure of a shear unit section equipped in the slitterscorer according to the present invention.
  • Knife heads 4 having knives 3 fixedly secured thereto as directed in the axial direction of the circumferential surface have a ring shape divided into a plurality of pieces along an axial direction of a pivotably supported shaft 5, the respective knife heads can slide in the axial direction (the widthwise direction of the corrugated cardboard sheet) via keys 6 interposed between the heads 4 and the shaft 5, and also they can be fixed at predetermined positions.
  • reference numeral 10 in Fig. 1 designates an electromagnetic clutch brake for transmitting rotation from a driving device not show to the shaft 5 at a predetermined timing.
  • an anvil cylinder 12 having an elastic body 12 fixedly secured onto its circumferential surface, a gear 13 is fixedly secured to one end of the same anvil cylinder, and it is meshed with the gear 7 fixedly secured to the above-mentioned shaft 5.
  • the opposite axial ends of the anvil cylinder 12 are also pivotably supported via bearings 14a and 14b from the frames 9a and 9b.
  • notches directed in the widthwise direction of a corrugated cardboard sheet 1 can be formed at desired positions on the sheet by synchronized rotation of the knife 3 having a plurality of knife heads 4 mounted thereon as disposed at predetermined positions along the widthwise direction of the sheet in response to an operation signal and the elastic body 11 on the anvil cylinder 12 with the sheet 1 pinched therebetween.
  • Fig. 4 is a schematic view showing one example of setting of the shear unit and notches formed on a corrugated cardboard web 2 as a result of the setting.
  • setting of the knife heads 4 there are various methods such that they are moved to and set at predetermined positions by a setting function of a slitter knife 22 in the slitterscorer main body or by a well-known individual setting function via a carrier 15 which is movable in the axial direction of the shaft 5.
  • notches can be formed only at necessary locations by moving and setting the knife heads 4, there is no need to perfectly cut the corrugated cardboard sheet 1 over the entire width as is the case with the slitterscorer in the prior art, stable transfer of sheets can be maintained, and the problems in the prior art such that a precision in the sheet cut length L in the next step of the process is deteriorated or troubles in transfer of the sheets are generated by jam-up, can be resolved.
  • a shear unit for forming notches (slots) at a plurality of locations in the widthwise location of a corrugated cardboard sheet is provided, even in the case of order change in multi-sheet production, the sheet is not cut and separated over the entire region in the widthwise direction as is the case with the slitterscorer in the prior art, and therefore, jam-up in the next step of the process which was generated upon order change at a high speed or upon order change for a sheet having a poor rigidity, can be prevented.
