When T is smaller, lifting height is inhibited compared with the lifting height H2 prevented when releasing, sanction can be eliminated in H1
The unhelpful rising of scissors 4.If the stacking thickness T of cloth 10 is larger, the rising of reciprocal head 5 is not prevented with lifting position-limit device 11
Mode release prevention.H2 corresponds to the range of lifting actuator 6, and H1, which becomes from H2, subtracts switching actuator 12
Value after actuating length.For example, by the way that H1 is reduced to 70~80% or so of H2, and obtain the rise time contracting of reciprocal head 5
Short effect.
In Fig. 2, the blocked state of the rising of the reciprocal head 5 for Fig. 1 is shown with (L) of left-half, uses right half part
(R) show prevent releasing state.In the example shown, under any state, the lower end of shearing knife 4 is all from the surface of cloth 10
It rises, is also able to carry out the grinding based on grinding mechanism 8b.But if the stacking thickness of cloth 10 becomes larger, worry cloth 10
Surface rises compared to the lower end of shearing knife 4 shown in left-half (L).Lower end as shearing knife 4 can not be from the table of cloth 10
The case where face is extracted is worried to damage cloth 10 by shearing knife 4, or forcibly bend shearing knife 4 if making to cut the movement of head 3.
In this case, if become right half part (R) shown in such prevention releasing state, due to reciprocal head 5 rising and
The lower end of shearing knife 4 also rises, even if stacking thickness increases, can also extract from the surface of cloth 10 to the shearing knife for reaching rising
The stacking thickness of 4 lower end.
Under the prevention releasing state shown in right half part (R), lifting position-limit device 11 becomes the state risen, utilizes liter
Actuator 6 drops, and reciprocal head 5 can rise to until abutting member 14a abuts with lifting position-limit device 11.It is also possible that even if rising
The upper limit that actuator 6 makes reciprocal head 5 rise to stroke drops, and abutting member 14a is not abutted with lifting position-limit device 11 and generated gap.
But if gap is big, between the actuating length of the switching actuator 12 of the difference H2-H1 as height from range as subtracting
Value after gap.Although the height of the lifting position-limit device 11 when can also release the prevention based on switching actuator 12 is set as low
In H2, but the actuating length for going up and down actuator 6 is less than range.In order to effectively using lifting actuator 6, switching actuator 12
Range, preferably prevent release when gap be exactly 0.
Fig. 3 indicates the composition of prevention and its releasing for switching the lifting position-limit device 11 based on Fig. 1.Supporting member 15

And it rotates.Rotation driving relative to grinding unit 8 is also carried out using the motor for being installed on supporting member 15, but saves sketch map
Show.
In addition, being able to use air cylinder pressure in lifting actuator 6, switching actuator 12, pressing actuator 21a.Also can
Enough using hydraulic or electronic cylinder, solenoid etc..
Fig. 4 indicates that preventing the rising of the reciprocal head 5 of the lifting position-limit device 11 based on Fig. 1 and rise the releasing prevented carries out
The movement of switching.If loading cloth 10 cutting workbench 2, becomes lifting position-limit device 11 in step s1 and prevent to release shape
State and increase reciprocal head 5 using lifting actuator 6, increase cloth pressing piece 9.Make to cut head 3 for example in step s2
It is mobile to origin position.In step s3, makes to press actuator 21a movement, decline cloth pressing piece 9.In step s4, lead to
Detection unit 20 is crossed, the stacking thickness T of the height detection cloth 10 stopped by the surface of the pressing cloth 10 of cloth pressing piece 9.
In step s5, thickness T will be laminated compared with a reference value in the stacking thickness comparing unit 31 of switch unit 30.Reference value is
The maximum assumed as cutter 1 is laminated 75% or so of thickness or based on the lifting actuator 6 risen under blocked state
50% or so of the lifting travel of reciprocal head 5.
In step s5, when being judged as stacking thickness T no more than a reference value, make lifting position-limit device 11 dynamic in step s6
Make, becomes rising blocked state.It should be noted that theoretically including the case where being less than a reference value and wait no more than a reference value
In a reference value the case where.But be actually judged as and hardly happened equal to the case where a reference value, therefore, to be greater than a reference value
Or less than a reference value judgement based on, equal to the case where may include any situation in size.
Then step s6 declines reciprocal head 5, the cutting of the cloth 10 based on shearing knife 4 is carried out in step s7.For
Shearing knife 4 is extracted before increase reciprocal head 5 from cloth 10, detects cloth 10 using detection unit 20 in step s8
Stacking stacking thickness T.In step s9, thickness T and preset cloth point will be laminated in stacking thickness comparing unit 31
Amount benchmark compares.The cloth component benchmark is set as to a reference value plus the value after permissible value.If thickness T, which is laminated, is not more than cloth
Expect component benchmark, then return to step s7, continues the cutting under the rising blocked state after acting lifting position-limit device 11.
In step s9, when being judged as that stacking thickness T is greater than cloth component benchmark, by lifting position-limit in step s10
Device 11 is set as preventing releasing state.It is judged as when stacking thickness T is greater than a reference value in step s5 and continues in step s1
Prevention release state, or in step s10 by lifting position-limit device 11 be set as prevent releasing state when, continue step
The cutting of s11 terminates movement if being judged as that cutting terminates in step s12.This is because the cloth point in step s9
Amount increase when, due to cutting progress and raising a possibility that heaving increase of cloth 10, release rise blocked state it is better
Situation is more.
As previously discussed, also thickness T is laminated in detection to detection unit 20 in cutting, about prevention switch unit 32, even if
The stacking thickness T-phase cut before starting is small for a reference value and prevent the rising of reciprocal head 5, if thickness T-phase is laminated for preparatory
The cloth component benchmark of setting increases, then also switches to the rising for not preventing reciprocal head 5.In the stacking for cutting the cloth after starting
In thickness T, though generate based on from cutting portion air leakage etc. cloth component, if the increased layer due to cloth component
Folded thickness T is less than cloth component benchmark, then also eliminates unhelpful rising, if more than benchmark, then release rising blocked state, even if
The case where lifting actuator 6 rises reciprocal head 5, and being also avoided that the lower end of shearing knife 4 can not extract from the surface of cloth 10, and
It can be realized safety.
Fig. 5 indicates to prevent and its release by the rising for switching the reciprocal head 5 for carrying out the lifting position-limit device 11 based on Fig. 1
The grinding range of grinding can be realized, based on shearing knife 4.As shown in Fig. 5 (a), shape is released in the such prevention of Fig. 2 (R)
It is right using moving up and down for the shearing knife 4 based on reciprocal head 5 when the rising of the reciprocal head 5 based on lifting actuator 6 under state
In point of a knife 4a and knife edge 4b, the grinding based on grinding mechanism 8b can be carried out in the range of Gu.If keeping switching actuator 12 dynamic
Make, then makes the reciprocal head 5 risen using lifting actuator 6 such as decline shown in Fig. 2 (L), as shown in Fig. 5 (b), for shearing knife 4
Knife edge 4b, can be ground in the range of Gd.Therefore, as a whole, the reciprocal head 5 based on lifting position-limit device 11 is utilized
The prevention of rising release state and rise blocked state, the grinding model for shearing knife 4 based on grinding mechanism 8b can be made
The range moved up and down for enclosing G compared to the shearing knife 4 based on reciprocal head 5 expands.In the past, this range expanded makes to grind by setting
The dedicated actuator that unit 8 moves up and down is ground to realize.In the present embodiment, can using switching actuator 12 and dual-purpose.
In the above embodiment, lifting position-limit device 11 is moved up and down along prevention path 11a, in the case where rising blocked state
The rising of reciprocal head 5 is prevented in preset position corresponding with the stacking a reference value of thickness T, but can also be from relative to resistance
Only path 11a different directions is haunted and is prevented.In the case where preventing releasing state, it can also make lifting position-limit device 11 to reciprocal
It is exited outside first 5 lifting range.
In addition, lifting position-limit device 11 becomes that rise the position of blocked state be 1 position in the present embodiment, but can also be
Multiple positions, which become, rises blocked state.If successively carrying out rising blocked state at multiple positions and preventing cutting for releasing state
It changes, then can make to prevent the position of the rising of reciprocal head 5 lower in the case where the stacking thickness T of cloth 10 is small, can be improved
The effect that the rise time of reciprocal head 5 shortens.If the stacking thickness T of cloth 10 increases, it is able to achieve and is corresponding in turn in big base
Standard is worth and becomes the switching for rising blocked state in preset position, is able to achieve safety, and the effect that retention time shortens.
In addition, the rising about the reciprocal head 5 based on lifting position-limit device 11 prevents, detect the stacking thickness T of cloth and into
Row switching control, but can also be carried out according to the judgement of the operator cut when starting etc..Also judging result can be utilized,
Indicate for cutter 1 movement when, in advance to be set as rise blocked state also be set to prevent releasing state cut
It changes and makes its movement.Moreover, also can be in the cut data for cutting cloth using cutter 1 comprising being based on lifting position-limit device 11
Reciprocal head 5 rising prevent switching, be set to carry out to exist cut degree until prevent rising, after progress not
It prevents to rise.
