Because Fig. 2 watches from the downstream of throughput direction, be therefore in the state be engaged all the time between upper slitter 42 and lower cutter 44.
Multiple lower cutter 44 is fixed on the lower module 59 be configured in below lower cutter 44, and lower module 59 is fixed on the upper surface of lower bolster 50.Lower bolster 50 and lower module 59 are with non-movably fixed form formation.Thus, lower cutter 44 be arranged to relative to can moving knife and upper slitter 42 as dead knife.
The bias component 52 upwards boosting cope match-plate pattern 48 from inferior offset is provided with at the lower surface of cope match-plate pattern 48.Bias component 52 comprises pin 54 for abutting with the lower surface of cope match-plate pattern 48, upwards boost the spring 55 of pin 54 with spring force from below and for covering the housing 56 around pin 54 and spring 55.
Pin 54 is connected to the lower surface of the upstream side along throughput direction of cope match-plate pattern 48, makes the upstream side along throughput direction of cope match-plate pattern 48 increase centered by turning cylinder 47.
Above cope match-plate pattern 48, be provided with pressing component 58, this pressing component 58 is for falling with predetermined timing interval underground and press the upper surface of cope match-plate pattern 48.Pressing component 58 comprise with undertaken by not shown die device 22 (with reference to Figure 13) move up and down the base portion 58a that action is carried out in the action linkedly and abutting part 58b given prominence to downward from base portion 58a.What utilize hydraulic cylinder etc. to carry out die device 22 moves up and down action.
If pressing component 58 declines and presses the upstream side along throughput direction of cope match-plate pattern 48 from top, then cope match-plate pattern 48 limit makes spring 55 compress limit decline, makes upper slitter 42 decline and remove cutting metal shoestring 10 gradually from the upstream side of throughput direction towards upstream side.
In addition, said driver part is equivalent to upper module 46, cope match-plate pattern 48, bias component 52 and pressing component 58 in detail in the claims.
In addition, although omit in fig. 2, as Fig. 3 ~ be provided with parts pressing device 60 as shown in Figure 5, this parts pressing device 60 abuts for the upper surface of the upstream-side-end along throughput direction with cope match-plate pattern 48 upper end position limiting cope match-plate pattern 48.

Fig. 5 illustrates that pressing component 58 declines and the position leaning on the upstream side of throughput direction compared to turning cylinder 47 of abutting part 58b pressing cope match-plate pattern 48 further compared with the state of Fig. 4.So the cope match-plate pattern 48 utilizing turning cylinder 47 to be rotatably kept on vertical guide overcomes the bias force of bias component 52, and rotates in the mode of the upstream side of throughput direction movement downwards centered by turning cylinder 47.Therefore, upper slitter 42 declines and is engaged in the upper entirety of length direction (throughput direction) with lower cutter 44, completes the cutting of metal band-shaped body 10.
(the 2nd embodiment)
Then, the 2nd embodiment of cutter sweep of the present invention is described according to Fig. 6 ~ Figure 11.In addition, for the structural element identical with the 1st embodiment, mark identical Reference numeral, the description thereof will be omitted sometimes.
In addition, in the present embodiment, adopt this linkage of the rotational action on the vertical guide shift action to throughput direction of the reciprocating member 72 of conveying device 70 being transformed into upper slitter 42, its concrete structure and action are below described.
Fig. 6 is the front view of the 2nd embodiment of cutter sweep.Fig. 7 is the A-A sectional view in Fig. 6, and Fig. 8 is the B-B sectional view in Fig. 6.Multiple upper slitter 42 is fixed on upper module 46, and upper module 46 is fixed on cope match-plate pattern 48.
Two sides of the width (direction orthogonal with the throughput direction of metal band-shaped body) of cope match-plate pattern 48 are provided with turning cylinder 47.Cope match-plate pattern 48 can rotate centered by turning cylinder 47 along with the rotational action of turning cylinder 47 on vertical guide.Turning cylinder 47 is supported on foundation pier 51 by bearing 49.This turning cylinder 47 is configured at the downstream along throughput direction of cope match-plate pattern 48.
The link component 62 for making turning cylinder 47 drive is linked with respectively in the outboard end of each turning cylinder 47.
The top in the downstream along throughput direction in link component 62 is formed with arcuation groove the 65,2nd link component 64 for linking with the 2nd link component 64 for transmitting the action of self-conveying apparatus 70.The pin 66 of the upper end being arranged on the 2nd link component 64 is inserted with in arcuation groove 65.Pin 66 can coordinate the action of the 2nd link component 64 and move in arcuation groove 65.Pin 66 carries out action in arcuation groove 65, and pin 66 makes the downstream along throughput direction of link component 62 to rotate centered by the upstream side of throughput direction thus.
The upper end of the 2nd link component 64 links by pin 66 and link component 62, and bottom links by the reciprocating member 72 of pin 69 with conveying device 70.Be formed with the straight-line groove 73 that the length direction along the 2nd link component 64 extends in the bottom of the 2nd link component 64, extend to side and the pin 69 be fixed is inserted in straight-line groove 73 from reciprocating member 72.
In addition, centered by fixed axis 67, on vertical guide, rotatably keep the substantial middle place on the above-below direction of the 2nd link component 64.
Because pin 69 moves in the horizontal direction together with reciprocating member 72, therefore pin 69 promotes the bottom of the 2nd link component 64 and the bottom of the 2nd link component 64 is rotated centered by fixed axis 67.
As mentioned above, if the reciprocating member 72 of conveying device 70 moves in the horizontal direction, then the bottom of the 2nd link component 64 is also drawn by pin 69 and rotates.Because the 2nd link component 64 rotates centered by the fixed axis 67 being set in the substantial middle place of above-below direction, therefore action is carried out in the mode to the counter-rotation contrary with the rotation direction of bottom in the upper end of the 2nd link component 64.
Here, conveying device 70 is described.
Conveying device 70 is for the device along throughput direction transferring metal shoestring 10 off and on, the reciprocating member 72 of movement in the horizontal direction can move back and forth between initial position and transfer position and draw metal band-shaped body 10.Outstandingly upward on the upper surface of reciprocating member 72 be configured with conveying pin 76, conveying pin 76 to enter in the band collar open-work 12 (with reference to Figure 12) that is formed on metal band-shaped body 10 also leash collar open-work 12 and make metal band-shaped body 10 move to transfer position (state of Fig. 9) from below.
If metal band-shaped body 10 arrives transfer position, then reciprocating member 72 stops mobile, and carries pin 76 to decline in the mode carrying collar open-work 12 and depart from downwards.If conveying pin 76 declines, then reciprocating member 72 starts to move (state of Figure 10) to initial position.
And if reciprocating member 72 arrives initial position, then reciprocating member 72 stops mobile (state of Figure 11).Then, conveying pin 76 rises and enters in the band collar open-work 12 of metal band-shaped body 10, and becoming can the state of transferring metal shoestring 10.
Then, the action be used for the conveying action of conveying device 70 cutter sweep 30 of cutting metal shoestring 10 is linkedly described according to Fig. 9 ~ Figure 11.
As shown in Figure 9, from utilizing conveying device 70 metal band-shaped body 10 to be transported to beginning cutting action the state of transfer position.On this position, the throughput direction sidesway to accompanying drawing dextrad send the reciprocating member 72 of conveying device 70.
In addition, now, move to throughput direction under the effect of the pin 69 that the bottom being linked to the 2nd link component 64 of reciprocating member 72 is given prominence in the side from reciprocating member 72.Therefore, the upper end of the 2nd link component 64 is moved to the direction contrary with throughput direction and is configured to make pin 66 be positioned at the upstream-side-end along throughput direction of the arcuation groove 65 of link component 62.
Then, as shown in Figure 10, if reciprocating member 72 moves to the direction contrary with throughput direction to return initial position, then the pin 69 given prominence to from the side of reciprocating member 72 promotes the bottom of the 2nd link component 64 in straight-line groove 73 to the direction contrary with throughput direction.The bottom of the 2nd link component 64 is promoted by the direction contrary with throughput direction, and the 2nd link component 64 rotates centered by fixed axis 67 thus, and its upper end is moved to throughput direction.
If the upper end of the 2nd link component 64 is moved to throughput direction, then the pin 66 of the upper end of the 2nd link component 64 is mobile in arcuation groove 65 promotes link component 62 simultaneously upward.
If under the action of the 2nd link component 64, rising along on the downstream of throughput direction of link component 62, then link component 62 entirety is rotated centered by turning cylinder 47.That is, turning cylinder 47 rotates to the direction that the upstream side along throughput direction of link component 62 declines.
Because turning cylinder 47 is fixed on cope match-plate pattern 48, therefore cope match-plate pattern 48 rotates centered by turning cylinder 47 in the mode declined along the upstream side of throughput direction.
Thus, the mode that the upper slitter 42 being fixed on cope match-plate pattern 48 declines by the upstream side made along throughput direction to rotate centered by the downstream of throughput direction, from going to be engaged with lower cutter 44 gradually along the downstream of throughput direction towards the upstream side along throughput direction.
The state of Figure 11 illustrates that reciprocating member 72 arrives the situation of initial position.
Now, in the present embodiment, the 2nd link component 64 is positioned at the position extended along vertical, and the downstream along throughput direction of link component 62 is upwards boosted the top by the upper end of the 2nd link component 64.
And the amount of spin that turning cylinder 47 rotates to the direction that the upstream side along throughput direction of turning cylinder 47 declines becomes maximum.Therefore, the upstream side along throughput direction being fixed on the cope match-plate pattern 48 of turning cylinder 47 also moves to the maximum position of decline degree, and upper slitter 42 and lower cutter 44 become the state along the occlusion of throughput direction entirety.Therefore, the cutting of metal band-shaped body 10 is completed in this position.
Afterwards, reciprocating member 72 moves to the throughput direction that metal band-shaped body 10 should be made to move to transfer position.The action of the cutter sweep 30 when reciprocating member 72 moves to throughput direction can be understood as and makes the cutter sweep shown in Fig. 9 ~ Figure 11 carry out reverse action.
That is, if reciprocating member 72 moves to throughput direction, then carry pin 76 to draw metal band-shaped body 10 to throughput direction, and pin 69 make the bottom of the 2nd link component 64 move to throughput direction.
If the bottom of the 2nd link component 64 is moved to throughput direction, then the 2nd link component 64 rotates centered by fixed axis 67, and its upper end is moved to the direction contrary with throughput direction.So the pin 66 of the upper end of the 2nd link component 64 moves to descent direction in arcuation groove 65, the downstream along throughput direction of pressing link component 62 downwards.
So the direction that link component 62 makes turning cylinder 47 decline to the downstream of throughput direction is rotated, and the mode making the cope match-plate pattern 48 being fixed on turning cylinder 47 increase with the upstream side of throughput direction centered by turning cylinder 47 is rotated.So upper slitter 42 is removed gradually with lower being engaged of cutter 44, upper slitter 42 rotates to the direction that the upstream side along throughput direction rises centered by the downstream of throughput direction.
By like this, in the present embodiment, after completing 1 cutting, conveying device 70, to throughput direction transferring metal shoestring 10, carries out the action of the occlusion removed between upper slitter 42 and lower cutter 44 simultaneously in cutter sweep 30.
Present embodiment described above is such, determines this structure of the rotational angle of upper slitter 42 by adopting according to the amount of movement of the reciprocating member 72 of conveying device 70, if amount of movement more at least rotational angle also diminish, result Cutting Length also shortens.
As shown in Figure 10, when reciprocating member 72 moves distance L to the direction contrary with throughput direction, the length of action of upper slitter 42 and lower cutter 44 is L+ α, in addition, as shown in figure 11, when reciprocating member 72 moves distance 2L to the direction contrary with throughput direction, the length of action of upper slitter 42 and lower cutter 44 is 2L+ α, becomes the length of action of the displacement depending on reciprocating member 72.
So, in the present embodiment, due to Cutting Length can be made corresponding with the amount of movement of the metal band-shaped body 10 in conveying device 70, even if therefore when as illustrated in conventional art, (with reference to Figure 16), conveying capacity was less, also can avoid generating longer cutting blade.
In addition, in explanation so far, describe the cutter sweep of the metal band-shaped body 10 being formed with multiple band collar open-work, but the present invention also can be applicable to smooth metal band-shaped body, the cutting of resin-made shoestring.
