22, crank mechanism 24 and sealing mechanism 26.Delivery section 30 includes diaphragm motor 32 and film conveying mechanism 34.
Control device 100 executes the setting, operation and control of various data.Firstly, will from the external of control device 100
Capacity packing (for example, packaging number per unit time) is input to control device 100.In addition, control device 100 can also basis
The characteristic of sealer 20 and delivery section 30 sets the capacity packing of intermittent packaging machine 200.For example, intermittent packaging machine
The capacity packing of intermittent packaging machine 200 is input to control device 100 by 200 user.Then, control device 100 setting with
The corresponding virtual main shaft of the capacity packing of intermittent packaging machine 200.

Action mode is known as sealer action mode, and the action mode of delivery section 30 is known as to convey action mode.It is dynamic being only only called
In the case where operation mode, may include sealer action mode and conveying action mode both.
For example, the capacity packing of intermittent packaging machine 200 is set, and packaging energy of the control device 100 based on the setting
Power generates the sealer action mode being made of sealing starting position, sealing end position, Sealing period.In addition, control dress
It sets 100 and is generated based on set capacity packing by the defeated of package length, the conveying starting position of film 40 and film 40
It send and completes the conveying action mode that position is constituted.In addition, intermittent packaging machine 200 may also comprise the angle of storage crank mechanism 24
With the storage unit of sealing time started and end time.
Diaphragm motor 32 drives according to the conveying action mode that control device 100 generates.This exemplary film is electronic
Machine 32 is driven by the driving portion 10 of servo amplifier etc..Diaphragm motor 32 is as a result, with the rotation of preset conveying speed
Turn.In addition, the signal of the position of diaphragm motor 32 or speed is input to driving by the pulse generator PG of diaphragm motor 32
Portion 10.
Film conveying mechanism 34 is connected with diaphragm motor 32.Film conveying mechanism 34 is according to the rotation of diaphragm motor 32
Rotation is made to drive.Film 40 is delivered to close by film conveying mechanism 34 as a result, with speed corresponding with conveying action mode
Envelope machine 20.This exemplary film conveying mechanism 34 includes 2 and is configured to the roller clamped from the two sides of film 40.Wherein, film
The structure of conveying mechanism 34 is not limited to this example.
For example, conveying action mode to from film 40 conveying starting position to film 40 conveying complete position until it
Between the speed of conveying film 40 provided.The speed for conveying film 40 can be determined based on package length and wrapping cycle
It is fixed.In addition, conveying action mode is defined as so that completing position to the conveying start bit of film 40 from the conveying of film 40
Be set to only, with Sealing period correspondingly, stop diaphragm motor 32.
Sealing electric motor 22 drives according to the sealer action mode that control device 100 generates.Seal electric motor
22 include the motor driven by driving portion 10.Seal electric motor 22 as a result, with preset sealer electromotor velocity
To rotate.This exemplary sealer electromotor velocity is corresponding with the sealing angular speed of electric motor 22.Wherein, as long as making close
Envelope machine 20 acts, then sealer electromotor velocity is not limited to angular speed.In addition, the pulse generator PG of sealing electric motor 22 will
The signal of the position or speed that seal electric motor 22 is input to driving portion 10.
Crank mechanism 24 drives according to the spinning movement of sealing electric motor 22.Crank mechanism 24 makes to seal electric motor
22 are connected with sealing mechanism 26.Sealer 20 is with crank mechanism 24, wrapping cycle and crank mechanism 24
The crank period is corresponding.
Sealing mechanism 26 is connected by crank mechanism 24 and sealing electric motor 22.Sealing mechanism 26 is with motor-driven with sealing
The corresponding Sealing period of operation mode is sealed film 40.For example, sealing mechanism 26 is by adding multi-disc film 40
Heat so that be sealed film 40 each other.In addition, hereinafter being said for the detailed setting method of sealer action mode
It is bright.
Fig. 3 shows an example of the movement of crank mechanism 24 and sealing mechanism 26.Crank mechanism 24 is electronic by sealer
Machine 22 is driven and sealing mechanism 26 is opened and closed according to the movement of sealing electric motor 22.This exemplary sealing mechanism 26 wraps
Include sealing mechanism 26a and sealing mechanism 26b.
Sealing mechanism 26 utilizes sealing mechanism 26a and sealing mechanism 26b by film 40 from sandwich, thus to film
40 are sealed.This exemplary sealing mechanism 26 shows the case where sealing mechanism 26b is connected with crank mechanism 24, still
Sealing mechanism 26a can also be connected with crank mechanism 24.Sealing mechanism 26 makes according to the rotation angle of crank mechanism 24 as a result,
Sealing mechanism 26a and sealing mechanism 26b opening and closing.In addition, sealing mechanism 26a and sealing mechanism 26b can be respectively provided with spring.
As a result, under rotation angle corresponding to from sealing starting position to sealing end position, sealing mechanism 26 connects with film 40
Touching.
In stage (A), sealing mechanism 26a and sealing mechanism 26b are in mutually the state most separated.At stage (B)
In, crank mechanism 24 rotates clockwise from the state of stage (A), thus sealing mechanism 26a and sealing mechanism 26b with it is thin
Film 40 is in contact.Especially, in stage (B), the moment that sealing mechanism 26a and sealing mechanism 26b are in contact is shown.That is,
The position of the crank mechanism 24 in stage (B) corresponds to sealing starting position.
Sealing mechanism 26a and the immediate state of sealing mechanism 26b are shown in stage (C).Here, if crank mechanism
24 rotation speed is very fast, it is likely that sealing mechanism 26a and sealing mechanism 26b can collide with each other and will lead to device generation
Failure.It is therefore preferable that in sealing mechanism 26a and the close position sealing mechanism 26b, the speed for sealing electric motor is reduced
Until device will not generate failure.In stage (D), it will be separated by showing sealing mechanism 26a and sealing mechanism 26b
Preceding state.That is, the position of the crank mechanism 24 in stage (D) corresponds to sealing end position.In stage (E), show close
The state of sealing mechanism 26a and sealing mechanism 26b separation.
Here, making to seal electric motor 22 in the intermittent packaging machine being sealed after stopping film 40 with certain
In the case that speed is acted, Sealing period can change according to wrapping cycle.In this case, if changing packaging week
Phase can then generate stand-by time until the temperature of sealing mechanism 26 reaches predetermined temperature.In addition, shortening wrapping cycle
In the case of, the speed of sealer rises, and can lead to generate impact sound due to excessively colliding, or generate mechanical breakdown.For example, by
In the mutual collision of sealing mechanism 26, screw loosening or sensor failure can be made because of vibration.
In contrast, in intermittent packaging machine 200 with the 1st wrapping cycle and 2nd packaging shorter than the 1st wrapping cycle
In the case where sampling action, this exemplary control device 100 suitably changes close in the 1st wrapping cycle and the 2nd wrapping cycle
The action mode of envelope machine 20.For example, in the case where intermittent packaging machine 200 is with the movement of the 2nd wrapping cycle, control device 100
The sealer speed phase of sealer electromotor velocity and the 1st wrapping cycle during making film 40 and sealer 20 be in contact
Together, sealer speed before making to contact after film 40 and sealer 20 just separation to sealer 20 is compared to the
The sealer electromotor velocity of 1 wrapping cycle rises.
As a result, intermittent packaging machine 200 be not necessarily to for wrapping cycle change sealer temperature, so as to shorten it is standby when
Between.This improves the packaging efficiencies of intermittent packaging machine 200.In addition, intermittent packaging machine 200 makes film 40 and sealer
20 be in contact in the case where sealer electromotor velocity become certain, it is and unrelated with wrapping cycle, therefore be not likely to produce excessively
The problem of collision.
Fig. 4 shows an example of the sealer action mode of intermittent packaging machine 200.In this example, between showing
Formula of having a rest packing machine 200 has the case where 2 different capacity packings.Wrapping cycle A is lower than the capacity packing of wrapping cycle B.
In addition, this exemplary sealer action mode is an example, it can be according to capacity packing, the sealing electric motor speed that can be set
The range etc. of degree changes.
The control of mutual Sealing period is certain in wrapping cycle A and wrapping cycle B by control device 100.That is, control
Device 100 processed controls the sealing time started S being made so that in wrapping cycle AAWith sealing end time EADifference and wrapping cycle
Sealing time started S in BBWith sealing end time EBDifference it is equal.Wrapping cycle A is an example of the 1st wrapping cycle,
Wrapping cycle B is an example of the 2nd wrapping cycle.
In addition, sealer electromotor velocity control when control device 100 contacts film 40 and sealer 20 is certain
(Vs).That is, the control of control device 100 is made so that sealing time started SAWith sealing end time EADifference during in it is close
Seal the sealing time started S in electric motor speed and wrapping cycle BBWith sealing end time EBDifference during in sealing
Electric motor speed is equal.Sealer 20 can steadily be sealed film 40 as a result,.In addition, in this specification, it will be thin
When the case where film 40 is in contact with sealer 20 is known as contacting, and by film 40 and sealer 20 not in contact with state be known as non-connect
When touching.
Control device 100 to it is non-contact when sealer action mode control.In one example, control device
The slope of sealer electromotor velocity when 100 controls are made so that non-contact becomes certain.In addition, control device 100 can be right
Sealer action mode be controlled such that the rising of speed of sealing electric motor, holding, decline each time become
It is equal.In other words, control device 100 controls each time for being made so that rising, holding, decline when respectively becoming non-contact
The 1/3 of period.
Control device 100 changes sealer action mode, to make according to the capacity packing of intermittent packaging machine 200
Sealing period becomes certain and unrelated with capacity packing.For example, even if being packed in the case where improving capacity packing with being promoted
The speed for the sealing electric motor 22 for comparing control device 100 also when sealer 20 being made to be in contact with film 40 before ability becomes
Centainly.In addition, compared with promoting capacity packing before, control device 100 makes sealer in the case where improving capacity packing
20 with film 40 not in contact with when sealing electric motor 22 velocity variations.For example, this exemplary control device 100 control at
So that the maximum value of the sealer speed of wrapping cycle A, the acceleration time until maximum value (accelerate compared to wrapping cycle B
Degree) and at least one of deceleration time (deceleration) since maximum value it is smaller.Wherein, as long as each wrapping cycle
Each wrapping cycle can make the speed of sealing electric motor that crank circles, then sealer action mode is not limited to originally show
Example.
Control device 100 after sealer 20 is separated with film 40 until be in contact with film 40 next time to sealing
Electric motor speed carries out trapezoidal control.That is, control device 100 carries out trapezoidal control to sealer electromotor velocity when non-contact
System.Control device 100 is by carrying out trapezoidal control to sealer electromotor velocity, to prevent sealer speed from excessively rising.
This exemplary control device 100 carries out sealer electromotor velocity in wrapping cycle A and wrapping cycle B the two trapezoidal
Control.It in addition, this exemplary sealer action mode is known as trapezoidal control for convenience, but include logical in actual control
It crosses and the case where being controlled with generally trapezoidal sealer action mode is combined to sine wave etc..
Fig. 5 shows an example of the sealer action mode of intermittent packaging machine 200.Wrapping cycle C is than wrapping cycle D
Capacity packing want low.Wrapping cycle D is equal with wrapping cycle B.Control device 100 by Sealing period control be it is certain, therefore,
Sealing time started S in wrapping cycle CCWith sealing end time ECDifference and wrapping cycle D in sealing time started SDWith
Seal end time EDDifference become it is equal.Wrapping cycle C is an example of the 1st wrapping cycle, and wrapping cycle D is the 2nd packet
Fill an example in period.
This exemplary control device 100, which controls the sealer action mode being made so that in wrapping cycle C, becomes triangular wave.
For example, control device 100 acts sealer in the case where the maximum value of sealer electromotor velocity is less than threshold values Vth
Mode is set as triangular wave.On the other hand, control device 100 is more than the feelings of threshold values Vth in the maximum value of sealer electromotor velocity
Under condition, sealer action mode is set as trapezoidal wave.Here, the variation of the sealer electromotor velocity in sealer action mode
Smaller, then power consumption more reduces.This exemplary control device 100 generates the sealer action mode that form triangular wave, therefore, energy
Enough reduce the power consumption of intermittent packaging machine 200.
Fig. 6 shows an example of the sealer action mode of intermittent packaging machine 200.Wrapping cycle E is than wrapping cycle F
Capacity packing want low.Wrapping cycle F is equal with wrapping cycle B.When control device 100 contacts film 40 and sealer 20
Sealing period control be it is certain, therefore, the sealing time started S in wrapping cycle EEWith sealing end time EEDifference and packaging
Sealing time started S in period FFWith sealing end time EFDifference it is equal.Wrapping cycle E is that one of the 1st wrapping cycle shows
Example, wrapping cycle F is an example of the 2nd wrapping cycle.
Sealing before this exemplary control device 100 makes film 40 be in contact with sealer 20 in wrapping cycle E is electromechanical
Sealer speed Vs when motivation speed is in contact than film 40 with sealer 20 is slow.That is, control device 100 make film 40 with
Sealer electromotor velocity before sealer 20 will be in contact is slack-off, therefore sealing mechanism 26 can be prevented mutual sharply
Collision.
Fig. 7 shows an example of the sealer action mode of intermittent packaging machine 200.Wrapping cycle G is than wrapping cycle H
Capacity packing want low.Wrapping cycle H is equal with wrapping cycle B.When control device 100 contacts film 40 and sealer 20
Sealing period control is certain, therefore the sealing time started S in wrapping cycle GGWith sealing end time EGDifference and packaging week
Sealing time started S in phase HHWith sealing end time EHDifference it is equal.Wrapping cycle G is that one of the 1st wrapping cycle shows
Example, wrapping cycle H is an example of the 2nd wrapping cycle.
This exemplary control device 100 is in wrapping cycle H, before film 40 is in contact with sealer 20, by sealer
Electromotor velocity control is certain.In addition, control device 100 after film 40 is separated with sealer 20, makes to seal electric motor
Velocity variations.That is, sealing start before or start after sealer electromotor velocity and Sealing period in sealer speed at
For identical speed.Control device 100 inhibits the sealing to sealer 20 dynamic by change sealer electromotor velocity as a result,
Make the influence generated.
Intermittent packaging machine 200 can prevent the excessive collision of sealer 20 when accelerating wrapping cycle, touch due to reducing
Sound is hit to which the environment of production scene is improved, the mechanical breakdown due to excessively colliding generation is reduced.Intermittent packaging
Machine 200 so that kinergety when colliding sealer becomes certain, and is made by making sealer electromotor velocity become certain
The collision of sealer 20 becomes certain.Movement when sealing is remained as a result, certain and unrelated with wrapping cycle, therefore sealed
Stay in grade.
As described above, the position that control device 100 generates crank mechanism 24 by the operation of sealer action mode refers to
It enables.More specifically, control device 100 can be executed by the calculated ratio such as virtual main shaft and sealing electric motor 22
The operation of sealer action mode.
In one example, control device 100 is according between the wrapping cycle and Sealing period of intermittent packaging machine 200
Relationship carries out operation to sealer action mode.For example, control device 100 is set as virtual spindle speed: sealing electric motor
22 speed=A:B ratio.
Here, A and B are defined respectively as:
A [PLS]=Sealing period [sec] × virtual spindle speed [PLS/sec]
B [PLS]=(sealing end position [deg]-sealing starting position [deg]) × C [PLS/shot]/360 [deg/shot]
Wherein, B≤0 C >.
C: the servo mechanism actuating quantity [PLS] of every 1 packaging
In addition, in the sealing moment, virtual main axle moving A [PLS], the sealing movement of electric motor 22 B [PLS].It is dynamic when sealing
Remain it is certain and unrelated with wrapping cycle, therefore, sealer stay in grade.When control device 100 is by making sealing as a result,
Between become certain, so that the superheat state of film 40 be made to become certain.
In addition, in one example, wrapping cycle of the control device 100 based on intermittent packaging machine 200 and sealer speed
Relationship between degree is sealed the mode operation of electric motor speed.For example, control device 100 is set as virtual main shaft speed
It spends [PLS]: the speed of sealing electric motor 22=virtual spindle speed [PLS/sec]: sealer speed [PLS/sec].Close
It seals the moment, sealing electric motor 22 is mobile A [PLS], virtual main axle moving B [PLS].
Here, A and B are defined respectively as:
A [PLS]=(sealing end position [deg]-sealing starting position [deg]) × C [PLS/shot]/360 [deg/shot]
Wherein, D≤0 C >.
C: the servo mechanism actuating quantity [PLS] of every 1 packaging
B [PLS]=A [PLS] × virtual spindle speed [PLS/sec]/sealer speed [PLS/sec]
As described above, the sealing that film 40 is in contact by control device 100 disclosed in this specification with sealer 20
Time control is unrelated with the wrapping cycle of intermittent packaging machine 200 to be certain, therefore, the sealing stay in grade of film 40.By
