Description

The cutting-off method of continuous sheet material
Technical field
The present invention relates to a kind of method that is used for continuous sheet material cut-outs such as corrugated boards, in more detail, relate to and a kind ofly cross over front and back that instruction changes and the corner tablet is remained continuous band-shaped, can under the situation that does not increase product cost, prevent the cutting-off method that crawls of corrugated board.
Background technology
In the past, will cut off on sheet material throughput direction (flow direction) by shearing machine along the corrugated board that supply line is carried continuously with a plurality of shearing machine swords.The structure of a plurality of shearing machines is respectively, can and not carry out at the loading horizontal plane of the cut-out of carrying out corrugated board moving along the vertical direction between the unloading horizontal plane of cut-out of corrugated board, can go up at the width (perpendicular to the direction of supply line) of corrugated board simultaneously and move, according to the instruction of getting the sheet situation or getting the sheet width, the shearing machine that selection is cut off, make it move and cut off, simultaneously, the shearing machine that does not cut off is moved to the unloading horizontal plane to loading horizontal plane.
On corrugated paper board production line, corrugated board is cut off continuously, the band shape that particularly produces specific width in the both sides of corrugated board is cut off lateral margin as the corner tablet, is attracted, reclaims by for example intake line etc. by the corner tablet recovering mechanism that is arranged on the shearing machine downstream.
When getting the sheet number and get the instruction variation of cut-outs such as sheet width, consider not stop supply line from the viewpoint of guaranteeing efficient, and to crossing over the shearing machine that new and old instruction is proceeded to cut off in a plurality of shearing machines, make it be accompanied by instruction and change, the setting of moving to the width of corrugated board from the off-position of old instruction off-position to new instruction.In this occasion,, therefore wish to shorten the required time that is provided with as much as possible because the corrugated board of carrying during being provided with goes out of use.
Be associated with this point, the viewpoint of the obstruction that causes because of the corner tablet of intake line when changing from preventing to instruct is considered, in the front and back that the instruction of the cut-out of crossing over the corrugated board that is undertaken by single shearing machine assembly changes, can make the corner tablet in that to become continuous band-shaped corrugated board cutting-off method on the direction of supply line open in Japanese kokai publication hei 10-86093 communique for example.
This cutting-off method comprises the shearing machine that carries out cutting edge at the continuous shearing machine that cuts off of new dictation trunk, moves to the off-position of new instruction under the state that cuts off corrugated board on width.Therefore, it can be the circular shearing machine sword that the center rotates freely with the axis vertical with respect to corrugated board that each shearing machine has, can be according to the feed speed control anglec of rotation of corrugated board.According to this cutting-off method, continue to remain under the machining state by each shearing machine that will in old instruction, cut off processing, its cutting edge Working position direction to new instruction on width is moved, once compared with shearing machine to the situation that unloading position is made a concession, can shorten motion track length and shorten the time that is provided with, can crossing over front and back that instruction changes simultaneously, that the corner tablet is become is continuous band-shaped.
But there is following technical problem in this cutting-off method.
The 1st, exist owing to the method for getting sheet, prevent the problem of the difficulty of crawling of corrugated board.In more detail, from reducing viewpoint, when each shearing machine changes in instruction, on width, move in order to cut off under the machining state in maintenance from the resistance of the corrugated board that is transferred, except making the shearing machine sword can rotate freely, the anglec of rotation is controlled.But, because the method for getting sheet, different to the number or the width movable length of the reverse shearing machine that moves of width by the number of the shearing machine that on width, moves or width movable length with quilt, make shearing machine with during keeping moving under the dissengaged positions, can produce crawling of corrugated board, the necessity that stops production line according to circumstances being arranged.
On the other hand, for the shearing machine that carries out cutting edge, from the corner tablet is sucked intake line well, prevent reliably on the viewpoint of obstruction of pipeline, on the supply line direction, cross over the continuous band-shaped of instruction variation front and back for it is become, it is moved on width under maintenance cutting edge machining state.
The 2nd, exist because each shearing machine is used for cutting edge with cutting off with the problem that causes with common.Say in further detail, be arranged at outermost a pair of shearing machine usually and be used for cutting edge, but according to the sheet situation of getting of new instruction or get the sheet width, also can carry out cutting edge by its inboard shearing machine.Therefore, for the ground, front and back that makes the corner tablet cross over the instruction variation keeps continuous band-shaped, the shearing machine that carries out cutting edge need move keeping carrying out under the cutting edge state on width the cutting edge position to new instruction, yet all shearing machines all can be rotated freely also can adjust the anglec of rotation, so can produce unnecessary equipment cost.
Therefore, in view of the above problems, the objective of the invention is to show a kind of cutting-off method of corrugated board, the content that the cut-out instruction of itself and corrugated board changes is irrelevant, can cross over ground, front and back that instruction changes and the corner tablet be remained continuous band-shaped, can under the situation that does not improve product cost, prevent crawling of corrugated board simultaneously.

Below, with regard to the action of shearing machine, the state of a control during mainly with modification of orders is that the center describes.Suppose under the state that the shearing machine assembly cuts off, imported modification of orders signal from the upper production management device 180 of Fig. 6 A.In the present embodiment, the sheet number of getting that is envisioned for current ordcurrent order is 3, and the sheet number of getting of next instruction is 2, and the situation that the width of corner tablet TM is widened in next instruction describes this control flow with Fig. 7 and Fig. 8.
At first, shearing machine 2 is positioned shearing machine sword 20 for Working position according to predefined process data, and processing is cracked.As shown in Figure 8, cutting from corrugated board under 3 the situation, corner tablet T1-1, T1-2 are being cut off by the head of shearing machine up and down 20A, the 20B in two outsides that are in corrugated board 1 width.As prerequisite, at first in S1~S3 of Fig. 7, from the position (C1~C5 of upper production management device 180 with each shearing machine sword 20 of shearing machine assembly 2, be the off-position of current ordcurrent order), in the same manner the position of each shearing machine sword 20 of next instruction (C1 '~C5 ', the i.e. off-position of next instruction) received as modification of orders information.In addition, sheet material transporting velocity VL is detected and is extracted by impulse generator 83 as shown in Figure 6A.At this, that direct requirement is position the C1 '~C5 ' of each shearing machine sword 20 of next instruction-side in modification of orders, but also can next instruction information such as sheet number, plate are wide, flanging width, cutting edge width calculate according to getting.
In S4 after this, by relatively present position and next instruction position C1 '~C5 ') calculate the amount of movement of plate width direction of each shearing machine sword 20 of next instruction side respectively.In addition, under the situation of getting the change of sheet number, in S5, the shearing machine sword (obsolete shearing machine sword) that in next instruction, unloads in the selected shearing machine sword 20.Then, in S6, the longest shearing machine sword begins from the location to finish required instruction transformation period Tc to the location to calculate in the shearing machine sword that all uses in old and new instruction positioning time.Thus, in S7,, calculate in the preparation that instruction changes according to the feed speed V1 that measures by velocity sensor 50, i.e. the length that corrugated board is supplied in instruction transformation period Tc, thus can determine the Ps position.
Then, in S8,, will cut off sword 56 and move to present shearing machine position, refer in particular to the width position of the shearing machine that carries out cutting edge with cutting edge shearing device 51.Be in more detail, drive servomotor 40, by bevel gear 40a, 36a, nut 36b, thread spindle 38, in advance the thin sword head 52,53 of circle is positioned at old instruction under the head of the shearing machine up and down 20 corresponding positions in two outsides of the width that is positioned at corrugated board 1 on.
Then, in S9, off-position according to new instruction, refer in particular to the width position of the shearing machine that carries out cutting edge, calculate the width displacement of cutting off sword 56, by this width displacement divided by the instruction transformation period Tc that calculates, the width translational speed when loading to calculate.
Then, in S10, when detect Pe by the time, once shearing machine sword 20 was being moved to the unloading horizontal plane on (S13), simultaneously will cut off sword 56 move to the loading horizontal plane on, carry out the cutting edge (S11) of corrugated board.Be in more detail, according to the mensuration of velocity sensor 50, instruction change point Pe arrive cutting edge shearing device 51 slightly before the time driven plunger 46, by carriage 64 will cut off sword 56 and rotary part 60 1 in the same way corrugated board 1 move.
Thereby, when instruction changes, at first be before instruction change point Pe, make and cut off sword 56 for example roughly to become stress state under the high speed of 0.5m/ second, so that undertaken by shearing machine sword 20 crack on maybe this crack near, begin to cut off from starting point P1-1, the P1-2 in the width of corrugated board 1 outside.Shown in Fig. 8 dotted line, owing to cut off the cut-out of sword 56 and urethanes cylinder 55 beginning corrugated boards 1.In this occasion, in order to cut the corner tablet of old instruction reliably, as shown in Figure 8, be preferably in Pe by before will cut off sword 56 and move to and load on the horizontal plane.
Then, in S12, cut off sword 56 and under the state that cuts off corrugated board, move to width with specific width direction speed.In more detail, drive servomotor 40, by bevel gear 40a, 36a, nut 36b, thread spindle 38, circular thin sword head 52,53 from the position of cracking (Ps is finished in=instruction variation) of corner tablet T1-3, the T1-4 of position to new instruction under that crack of old instruction corner tablet T1-1, T1-2 down so that for example roughly the high speed of 1m/ second is mobile at width.
At this moment, because corrugated board 1 continues to supply with continuously, cut-out sword 56 also is subjected to circular thin sword head 52,53 widths at corrugated board 1 and moves the resistance of generation in the resistance of the direction of the supply that is subjected to corrugated board 1.Thereby, cut off sword 56 and be subjected to two resistances, be the center rotation with swinging axle 65, towards the direction parallel with the resultant direction of two resistances.
In addition, also can be cut-out sword 56 and move at the width of corrugated board 1, it is towards the structure of carrying out Numerical Control in by not shown driven by servomotor.And, also can calculate tan according to the feed speed V1 and the translational speed V2 of cut-out sword 56 of corrugated board 1 at the width of corrugated board 1 -1V2/V1, the angle of the direction of the supply of the sword face of maintenance cut-out sword 56 and corrugated board 1 is tan in the cut-out of corrugated board 1 -1V2/V1.
As mentioned above, shown in the dotted line of Fig. 8, corrugated board is cut off under the state of the corner tablet of the corner tablet of crossing over old instruction and new instruction, and the corner tablet becomes band shape continuous on the supply line direction.
Then, in S15, when detecting, shearing machine sword 20 is moved to loading horizontal plane (S17), will cut off sword 56 simultaneously and move on the unloading horizontal plane (S16) by Ps.In more detail, change than instruction when finishing a Ps changing by instruction to finish on the Ps or to arrive by end point P1-3, P1-4 near the width outside of corrugated board 1, driven plunger 46 makes cut-out sword 56 together become the unloaded state that leaves corrugated board 1 with rotary part 60 by carriage 64.In this occasion,, be preferably in just by cutting off sword 56 behind the Ps and move to and unload on the horizontal plane for the corner tablet of the new instruction of incision reliably.Thus, each up and down new instruction the being positioned at instruction variation down of shearing machine head finish a Ps and finish.Thereby, cutting off by shearing machine sword 20, corner tablet T1-3, T1-4 are cut off.After, the processing under newly instructing by shearing machine 2.In addition, in the occasion that cuts 2 from corrugated board 1, make a part up and down shearing machine head 20 become dormant state in the unloading horizontal plane.
At this, as shown in Figure 8, the cut-out sword 56 of both sides is opposite at incline direction, moves on width and side by side forms towards direction approaching mutually on the width of corrugated board and cut off line.Thus, the cut-out sword 56 that produces in the sheet material both sides is cancelled out each other to the power of the plate width direction that sheet material applies, and is not easy to take place crawling of corrugated board.
In addition, when corner tablet T1-1, the T1-2 that cuts off under old instruction arrived leftover pieces pipeline 4, corner tablet T1-1, T1-2 were inhaled in the leftover pieces pipeline 4.And, when instructing variation, being inhaled into continuously in the leftover pieces pipeline 4 by the corner tablet and corner tablet T1-1, the T1-2 that cut off sword 56 cut-outs, corner tablet T1-3, T1-4 and this corner tablet under the new instruction are inhaled in the leftover pieces pipeline 4 continuously.
Like this, owing to each corner tablet T1-1, T1-2, T1-3, T1-4 are inhaled into leftover pieces pipeline 4 continuously, can prevent that corrugated board 1 from stopping up.If starting point P1-1, P1-2, end point P1-3, P1-4 instruction change point Pe, instruction change finish a Ps near, when sucking corner pipe material 4, can suck continuously, be not easy to produce disrumpent feelings and stop up.In this, do not need high accuracy owing to cut off the location of sword 56, the cost that can suppress positioner rises.
More than, understanding embodiments of the invention in detail, those skilled in the art can make various corrections or change in the scope that does not exceed claim of the present invention.For example, though be that example describes in the present embodiment with the corrugated board, the present invention is not limited to this, so long as continuously the sheet material of supplying with, change the sheet material that change gets the sheet situation or get the sheet width by instruction and all can.In addition, instruct the method for the cut-out track in changing though a kind of combining by the thin sword of the circle of sword face variable-angle has been described in the present embodiment, also can use the cut-out sword of the common knife-edge shape of sword face variable-angle to replace the cut-out sword 56 of the thin sword of circle of sword face variable-angle.In addition, though in the present embodiment the occasion that 1 shearing machine 2 only is set in the system corrugating machine is illustrated, even but when being provided with 2 shearing machines 2, during instruction when using 2 shearing machines simultaneously when using 2 shearing machines 2 simultaneously under old instruction or under new instruction changes, same with the occasion that only is provided with 1 shearing machine 2 of present embodiment, also can obtain same effect by being suitable for method of the present invention.
