To the cutting device utilizing above-mentioned formation, the action of cloth 10 being cut out to pattern-making sheet is described.
First, under the operation of operator, roll up 9 at the roller being placed with cloth on cloth rewinder roll of opening of planting-opener 8, open the instruction of cloth to control device 11 input.With its correspondingly, open cloth rewinder roll action, from roller volume 9 cloth 10 is extracted out.The leading section of the cloth 10 after extraction is positioned in the upper side of the end side of planting-opener 8 side of ribbon conveyer, to the instruction that control device 11 input extends, now, the cloth rewinder roll of opening of planting-opener 8 carries out extraction action, and ribbon conveyer carries out the conveying action of being carried to another side by cloth 10.Thus, cloth 10 extends to the cut out areas on the bearing-surface 3a cutting out workbench 2.It should be noted that, so-called " cut out areas " is for can utilize the cutter of cutterhead 7 to perform the region of cutting out.
When cloth 1 extends on the bearing-surface 3a cutting out workbench 2, under the operation of operator, will represent that the data of cutting out of cutting out the shape of pattern 50 input to control device 11.In the display of control device 11, showing the shape of cutting out pattern 50 corresponding with cutting out data or position, under the operation of operator confirming shown information, the position of cutting out pattern 50 on cloth 10 and angle being regulated.At the end of the adjustment of the position and angle of cutting out pattern 50, the instruction of cutting out beginning inputted to control device 11 by operator, control device 11 starts the control of cutting out based on this input.Below, the content of the control based on control device 11 is described.
First, control device 11 makes balladeur train 5 and the driving mechanism action of cutterhead 7, in the face parallel with bearing-surface 3a, drive cutterhead 7, the rotation sword 28 of cutterhead 7 is configured in start cloth 10 cut out cut out starting position.During making cutterhead 7 move to cut out starting position, utilize and move up and down working cylinder 15 and will move up and down framework 19 and remain on uppermost position in fig-ure, avoid rotating sword 28 and fixed blade 43 and block and hang on cloth 10.When cutterhead 7 arrive cut out starting position time, as shown in the arrow C 1 of Fig. 4, give prominence to make the connecting rod of fixed blade working cylinder 36, swing arm 37 swung leaf spring 40 away from, the mode that makes fixed blade 43 leave from bearing-surface 3a from fixed blade working cylinder 36.Then, start cutlery rotation motor 30 and driving makes rotation sword 29 rotate like that as indicated by arrowr, and make to move up and down working cylinder 15 action, to moving up and down the direction of framework 19 along bearing-surface 3a, namely driving downwards.Thus, the blade tip of the rotation sword 29 of rotation contacts with cloth 10, is formed with otch in the starting position of cutting out of cloth 10.At this, cloth 10 is bearing on the conveyer belt 3 of pile fabric shape, therefore, before rotating sword 29 through mistake and the pile 47 of conveyer belt 3 end in contact cloth 10 and effectively form otch, further, do not arrive the base fabric 46 of conveyer belt 3 owing to rotating sword 29 therefore the breakage of conveyer belt 3 can be prevented.
When cloth 10 cut out starting position be formed with otch time, rotation sword 29 is temporarily stopped, as shown in Figure 5, the connecting rod of fixed blade working cylinder 36 is sunk to.Thus, by shrink disc spring 39 active force and make swing arm 37 to fixed blade working cylinder 39 side oscillation, leaf spring 40 swings and makes fixed blade 43 close to bearing-surface 3a.When fixed blade 43 is close to bearing-surface 3a, under the active force of leaf spring 40, fixed blade 43 is in contact with it with the state of the side pressing the blade tip rotating sword 29.Meanwhile, make to move up and down working cylinder 15 action, to moving up and down framework 19 along the direction left from bearing-surface 3a, namely drive upward.Thus, cloth 10 lifts from bearing-surface 3a by fixed blade 43, and fixed blade 43 connects with the side of the close bearing-surface 3a of cloth 10, and rotates sword 29 and connect with the side away from bearing-surface 3a of cloth 10.Then, as indicated by arrowr, again start the rotary actuation rotating sword 29, to cutterhead 7 as shown by arrow F such front end along fixed blade 43 towards direction drive.It should be noted that, make above-mentioned fixed blade 43 close to bearing-surface 3a with rotate the blade tip of sword 29 and contact, and drives upward moving up and down framework 19 and by fixed blade 43, a series of action that cloth 10 lifts from bearing-surface 3a also can be carried out under the state of the rotation of continuation rotation sword 29.Above-mentioned cutterhead 7 is driven in the in-plane direction along the path corresponding to the shape of cutting out pattern, and drive cutlery framework 25 to circle round with driving direction correspondingly wraparound spin axis 22, utilize fixed blade 43 thus and rotate sword 29 and along cutting out pattern, cloth 10 is cut off, thus carry out pattern-making sheet.
So, when cutterhead 7 carries out the shearing operation of cloth 10, the reduction that there is the sharpness owing to rotating sword 29 or fixed blade 43 or the wrinkle that produces on cloth 10 and make excessive resistance act on the situation of fixed blade 43 from cloth 10.From cloth 10 excessive resistance in most cases, owing to interrupting based on the cutting line rotating sword 29 and fixed blade 43, fixed blade 43 is locked to the end of cutting line and produces.When there being excessive resistance to fixed blade 43 effect, as shown in Figure 6, the adsorbed portion of fixed blade support 42 opens due to the absorption affinity of permanent magnet 44, and fixed blade 43 is rotated as indicated by the arrows like that.Thus, to make the front end of fixed blade 43 make fixed blade 43 reverse towards the rightabout mode of the driving direction of the cutterhead 7 shown in arrow F.Now, reaction force is born from bearing-surface 3a in the front end of fixed blade 43, and like that leaf spring 40 swings upward as shown by arrows p 2, therefore the front end of fixed blade 43 can not be blocked and hung on bearing-surface 3a and fixed blade 43 is reversed sleekly.When leaf spring 40 swings and makes swing arm 37 swing, the swing of limit switch wobble detection bar 37 output detections signal, with its correspondingly, cutlery rotating motor 30 stops, and balladeur train 5 stops with the driving mechanism of cutterhead 7.
Like this, when excessive resistance acts on fixed blade 43 from cloth 10, fixed blade 43 is reversed and keeps out of the way from the driving path of cutterhead 7, and the driving of the rotation and cutterhead 7 that rotate sword 29 stops.Consequently, can prevent from fixed blade 43 from blocking hang on cloth 10 and make cloth 10 along the undesirable condition of the driving direction movement of cutterhead 7.In addition, the situation from the excessive resistance of cloth 10 pairs of fixed blade 43 continuous actions can be prevented, therefore, it is possible to prevent the breakage of cloth 10 or the breakage of fixed blade 43.And then make the rotation of rotation sword 29 stop, therefore, even if cloth 10 floats along with the reversion of fixed blade 43, and the cloth 10 after floating contacts with rotation sword 29, also can prevent the undesirable condition that cloth 10 is cut off abnormally.
In the above-described embodiment, the swing of limit switch to swing arm 37 as sensor detects, but also can detect the swing of leaf spring 40.In addition, sensor also can detect the reversion of fixed blade 43.
In addition, the cutting device 1 of above-mentioned embodiment is cut out the cloth as sheet material, but also can cut out other the sheet material such as leather, paper or resin.
In addition, the present invention is not limited to the cutting device of draught machine formula, also can be applicable to cutterhead and be fixed on the cutting device of assigned position or cutterhead only by the cutting device that drives along one direction.
