Definitions

  • the present invention relates to an order change apparatus for a corrugating machine for manufacturing corrugated fiberboard and a cutting apparatus used for the order change apparatus.
  • FIG. 8 shows an arrangement of the conventional corrugating machine on the downstream side of a rotary shear
  • FIGS. 9 to 12 show conventional order change methods (methods for making transverse cuts).
  • reference numeral 2 denotes a rotary shear.
  • the rotary shear 2 is provided with a knife cylinder 25 and an anvil cylinder 26.
  • the knife cylinder 25 has a knife 24 which is longer than the overall width of a corrugated fiberboard web 3, and the anvil cylinder 26 has an anvil cover 27 which is made of an elastic material such as rubber.
  • the rotary shear 2 is configured so as to cut the corrugated fiberboard web 3 in the width direction by holding the web 3 between the knife 24 and the anvil cover 27 and pressing it by them.
  • the paper joint portion of the corrugated fiberboard 3 and the defective portion thereof produced by other causes are cut off into a rectangular sheet of a given length by continuously rotating the rotary shear two or more turns, and the cut-off sheet is discharged downward by a defect removing device 42.
  • Reference numerals 1a and 1b denote slitter scorers.
  • the slitter scorer 1a, 1b is provided with a marking roll 28a, 28b and a slitter knife 29a, 29b.
  • the marking roll 28a, 28b makes fold lines for corrugated fiberboard box, and the slitter knife 29a, 29b slits the corrugated fiberboard web 3 in the flow direction with a predetermined width.
  • Reference numeral 22 denotes a cutoff.
  • the cutoff 22 cuts a slit web 5, which has been slit in the flow direction by the slitter scorers 1a and 1b, in the direction perpendicular to the flow with a predetermined length.
  • Reference numerals 30a and 30b denote trim ducts. The trim duct 30a, 30b attracts and removes trims 23a and 23b (see FIG. 9).
  • the corrugating machine produces sheets corresponding to various box sizes.
  • slitting in the flow direction and marking (marking line is not shown) of the corrugated fiberboard web 3 are performed by the slitter scorers 1a and 1b, and cutting in the direction perpendicular to the flow is performed with cut lengths Ld and Lt by the top and down cutoffs 22a and 22b, by which a corrugated fiberboard sheet of a predetermined size is produced.
  • the solid lines drawn in the lengthwise direction of the slit web 5 in FIGS. 9 to 12 and 16 indicate cut lines.
  • the produced corrugated fiberboard sheets have only one size at one time.
  • two cutoffs 22a and 22b are installed to produce the sheets of two sizes.
  • the slit web 5 cut by the down cutoff 22b is indicated by hatch rising at right
  • the slit web 5 cut by the top cutoff 22a is indicated by hatch rising at left.
  • C indicates the rotary shear cut line
  • arrow W indicates the web advance direction.
  • Order change means that the predetermined box size is changed. As shown in FIG. 9, in the new and old orders ND and OD before and after the order change region D, the slitting width by the slitter scorers 1a and 1b and the cutting length by the cutoff 22 differ.
  • a method is used in which if the old order OD is being slit by a slitter scorer 1a, the slitting and marking positions of the new order ND are set by the slitter knife 29b and the marking roll 28b of the slitter scorer 1b during the production of the old order OD, and the operating unit is changed over from the slitter scorer 1a to the slitter scorer 1b without stopping the operation at the time of order change.
  • the change of the cutting length of the cutoffs 22a and 22b is made by instantaneously changing over the electrical signals controlling the rotational speed of the knife.
  • the corrugated fiberboard web 3 is cut over the overall width in the direction perpendicular to the flow by the rotary shear 2 on the upstream side as shown by the dash-and-dot line in FIG. 9 assuming the order change region D in advance, and the order change region D is removed as a defective sheet by the defect removing device 42.
  • the slit web 5 going to the top cutoff 22a and the slit web 5 going to the down cutoff 22b of the new order ND are separated completely.
  • the control for making the cut portion by the rotary shear 2 coincide with the cut portion by the slitter scorers and cutoff on the downstream side is achieved by the synchronous control of the entire system.
  • FIG. 10 shows an improvement of FIG. 9.
  • the order change region D of a predetermined length is provided in FIG. 9, in order to decrease this length to the utmost (because the change region becomes defective paper), the slitter slit portions of the new and old orders are lapped, and this lap portion D' is separated by the rotary shear 2.
  • the leading end of the new order ND and the tail end of the old order OD cut by the rotary shear 2 become free by separation. Therefore, the leading end of the new order ND collides with a transfer guide member during the subsequent travel and jams up, or moves in a zigzag direction, resulting in a poor cutting accuracy. Also, the remaining web of the old order OD between the rotary shear 2 and the cutoff 22 produces a poor cutting accuracy by zigzag movement etc.
  • FIGS. 11 and 12 To solve the above problems, a method has been proposed in which as shown in FIGS. 11 and 12, only the portion between the slitter lines M, which are the separation lines of the top and down cutoffs 22a and 22b, is cut by a cut line NO.
  • An example shown in FIG. 11 is a case where the shift of M lines of the new and old orders is relatively small.
  • the webs 5(A) and 5(C) of the down side and the webs 5(B) and 5(D), 5(E) of the top side are joined together before and after the order change, so that the order change can be performed without separating the web.
  • K denotes an order change point.
  • FIGS. 14 and 15 show the construction of the cutting apparatus 4 used in this method.
  • a cutting nozzle 39 of water jet etc. runs across the corrugated fiberboard web 3 by means of an endless chain 15, by which N portion in FIG. 16 is cut.
  • a frame 7 is inclined around a frame 6 to make the length of order change region adjustable.
  • the order change region D in FIG. 16 is cut and removed as a defective portion by synchronously operating the cutoff on the downstream side.
  • the capacity of, for example, the aforementioned water jet 39 for cutting a corrugated fiberboard sheet is now limited to about 400 m/min depending on various conditions. Under this condition, when the corrugated fiberboard web 3 of 1 m wide is cut by merely moving the water jet cutting nozzle 39 laterally with respect to the web 3, the order change region D of about 1.8 m is required.
  • the order change region D is thrown away as a defective sheet because it cannot be used as the final product of corrugated fiberboard sheet. Therefore, the order change region D of 1.8 m is a length resulting in the decrease in production efficiency, so that the shortening of the order change region D has been demanded strongly.
  • An object of the present invention is to provide an order change apparatus and a cutting apparatus which can decrease the length of the order change region to the utmost with the cutting capacity of the present undirectional cutting device, can provide a cut shape having less jamming-up, and further have a simplified function and a compact size.
  • the present invention was made to solve the above problem, and provides an order change apparatus for a corrugating machine having a slitter scorer for slit cutting a corrugated fiberboard web into a plurality of sheets in parallel to the running direction and a plurality of cutoffs which are disposed on the downstream side of the slitter scorer to cut the introduced web in the direction perpendicular to the web running direction to branch a predetermined number of sheets, in which when order change is made, a portion which is not slit cut is provided between the leading end of a new order web and the tail end of an old order web, and the vicinity of tail end at the boundary slit line of the old order and the vicinity of leading end at the boundary slit line of the new order, which are made to branch on the downstream side of said slitter scorer, are separated, the order change apparatus comprising a frame rotatably installed around a support shaft provided substantially on the machine centerline, undirectional cutting means installed on the frame, cutter running means for running the cutting means on the frame
  • the undirectional cutting means such as a water jet and a laser cutter is run at a given angle to a reference line at right angles to the web advance direction.
  • This running direction at an angle is a direction such that the velocity component of the cutting means in the flow direction agrees with the flow direction of sheet (web).
  • the order change region is cut and removed as a defective portion by synchronously operating the cutoff on the downstream side.
  • the position of boundary slit of web is in the vicinity of machine center.
  • the frame is configured so as to be turned substantially around the machine center as described above, the swinging amount of cutting means when the frame is turned is small, so that the correction amount of control position is small.
  • the installation space required by the turning is about a half of the space for the conventional apparatus (in which the frame is turned in one direction).
  • the angle of the boundary slit line with respect to the web running direction is in the range of 30° to 60°.
  • the end on the non-connected side runs unstably, resulting in easy occurrence of jamming-up.
  • the boundary slit line has an angle of 30° to 60° with respect to the web running direction, the occurrence of jamming-up can be prevented by the relief effect by this inclination angle.
  • the cutting apparatus for the corrugating machine is configured as described below.
  • the cutting apparatus comprises two undirectional cutting means installed on a frame rotatably installed around a support shaft, chain track running means such as an endless chain for running the cutting means over the overall width of the web on the frame, and moving means for moving the frame to a preset angle with respect to the web running direction, the chain track running means are arranged oppositely so as to run in parallel to each other and in the reverse direction at least in the range of cutting, and the cutting means are provided on the opposite side of the running means.
  • the cutting apparatus has the rotation center of the frame substantially on the machine centerline, and an order change apparatus for a corrugating machine, in which defect removing means is added to the cutting apparatus, and which comprises the cutting apparatus and trim cutting means for making cut at a trim portion only.
  • the cutting direction of the cutting apparatus can be set freely, and the overall width can be cut with a short length, so that the apparatus can have a function of rotary shear.
  • the rotary shear can be omitted, and it is enough to provide a cutting apparatus having a trim cutting function only, so that the decrease in product cost can be achieved.
  • the present invention is configured as described above.
  • the undirectional cutting means are installed on the rotatable frame so as to run on the frame, the frame is moved to a preset angle with respect to the web running direction, and the direction of velocity component of the cutting means in the sheet advance direction agrees with the web advance direction. Therefore, the order change region can be shortened in high-speed order changing even with a limited cutting capacity of cutting means, loss sheet (defective sheet) can be decreased, the productivity can be improved, the installation space of machine can be reduced, and the manufacturing cost of machine can be lowered.
  • FIG. 1 is a plan view (view of arrow A in FIG. 2) of a cutting apparatus in accordance with a first embodiment of the present invention
  • FIG. 2 is a front view thereof.
  • reference numeral 7 denotes a pair of frames slidably supported on track faces 20.
  • the right and left frames 7, 7 are connected to each other by an upper beam 8 and a lower beam 12.
  • At the lower end of the frame 7 is installed running wheels 18 which are rotated by a motor 16.
  • a support shaft 19 which is rotatably supported by a bearing 11 on the ground.
  • the upper beam 8 is provided with sprockets 9 and 10, and an endless chain 15 is set over the sprockets 9 and 10.
  • the endless chain 15 is equipped with a cutting nozzle 39 for a water jet cutting device.
  • One driving sprocket 9 is directly connected to a motor 17, and the other driven sprocket 10 can be rotated freely. Therefore, when the motor 17 is rotated, the cutting nozzle 39 runs along the upper beam 8.
  • Reference numeral 41 denotes a computing unit, to which various data such as the web speed at the time of order change, the start and end positions of cutting by the cutting nozzle 39, the order change region setting length, and the like are inputted.
  • the computing unit 41 computes the optimum running angle and running speed of the cutting nozzle 39, and gives driving instructions to the motors 16 and 17.
  • reference numeral 21 denotes an angle detecting means for detecting the turning angle of the upper beam 8
  • 40 denotes a bearer installed below the cutting nozzle 39.
  • FIG. 3(a) shows a method of making cut when a web is cut by the cutting nozzle 39 using the water jet
  • FIG. 3(b) collectively shows the order change region lengths under various cutting conditions described below.
  • the cutting particulars of the cutting apparatus in this embodiment are as follows: Web speed at the time of order change 350 m/min Maximum cutting speed of water jet 400 m/min Cutting width (measured at right angles to the web advance direction) 1 m
  • the reason why the traveling direction of the cutting nozzle 39 can be inclined to both directions of up right and down right in FIG. 1 is that cutting must be done so that the direction of cut line is not only down right direction as shown in FIG. 3 but also up right direction depending on the size of sheet (web) before and after the order change.
  • the frame 7 In order to cut a sheet so that the cut line of the sheet 3 is in up right direction, the frame 7 is inclined so that the travel line of the cutting nozzle 39 is in the down right direction in FIG. 1, and the cutting nozzle is run from left to right.
  • the cutting apparatus is configured so that the frames 7 are rotated around the center of machine (also, the center of the corrugated fiberboard web 3). Therefore, as shown in FIGS. 6(a) and 6(b), if the inclination of ⁇ ° around the rotation axis O 1 requires a space of a total of 2 m, 1 m in each direction, in the conventional apparatus, it requires 1 m, a half of the above value, in this embodiment in which rotation is made around the machine center (rotation axis O 1 ). Thereby, the length for installing the corrugating machine is shortened.
  • the cut line M is most frequently in the vicinity of the machine center. Therefore, if the machine center is the rotation center of the frame and the inclination of the frames 7 changes, the position shift of the cutting nozzle 39 in the vicinity of the center in the flow direction becomes small, so that the cutting start position of the web 3 in the flow direction becomes more accurate.
  • the angle ⁇ of the cut line should be brought close to the right angle to the web flow direction.
  • the corner indicated by Z swings by the self weight or the air flow in running, becoming unstable, so that jamming-up occurs easily. If the angle ⁇ is small, the running stability increases, but the length of the order change region increases, resulting in the increase in loss. Therefore, the angle of the cut line should preferably be approximately 30° to 60° as shown in FIG. 5(b).
  • FIG. 4 is a front view of a corrugating machine in accordance with a second embodiment of the present invention.
  • the construction of the frame in this embodiment is the same as that in the first embodiment shown in FIGS. 1 and 2.
  • the endless chain 15 is set in the range over the width of the corrugated fiberboard web 3 so that the opposite portions 15a and 15b are formed in parallel so as to run in the direction opposite to each other.
  • Each of the opposite portions of the endless chain 15 is provided with a cutting nozzle 39a, 39b.
  • the defective sheet which is separated by plural continuous rotations of rotary shear in the conventional method, can be cut short in the flow direction even at a high speed.
  • FIG. 7 is an arrangement plan of an order change apparatus for a corrugating machine in accordance with a third embodiment of the present invention.
  • a defect removing device 42 and a cutting apparatus 43 for cutting trim only are added to the cutting apparatus 4 in the above-described second embodiment.
  • the web can be cut sufficiently short by the undirectional cutting apparatus, and substantially at right angles by the cutting apparatus 4 of the first embodiment so as to bring out the capacity of water jet cutter to the utmost. Therefore, the cutting of the overall width, which has conventionally been done by the rotary shear 2, can be done by the apparatus of the second embodiment.
  • a cutting apparatus 43 for cutting trim only may be installed.
  • the width of corrugated fiberboard web 3 ranges from the maximum width to about a half of the maximum width as the minimum width. Therefore, the trim cutting requires only the capacity for cutting about a quarter of the maximum width at each side of the corrugated fiberboard web 3. Since there is no need for cutting the central portion which most strongly affects bending, the apparatus can have low rigidity as compared with the conventional apparatus, so that the apparatus can be made compact and inexpensive.
