Embodiment
It will explain that cigarette-packaging machine is in Fig. 1 according to diameter determination of the present invention and application thereof by cigarette-packaging machine 10
In illustrate only a part.The cigarette-packaging machine 10 is used to add by the packaging material of relative stiffness, especially by (thin) cardboard
The especially cubical package 11 of work.However, the present invention can be also used in the feelings of other packing machines for other products certainly
In condition.
In the case of packing machine 10, using the web shape packaging material from film, to produce film blank by the film
12, each cigarette packages 11 are wrapped in the film blank.Film blank 12 forms the oversheath of each package 11.
Here film blank 12 is by being initially that the membrane material of web shape is made, and the membrane material is in the region of unification station
In each single film blank 12 is cut into by unification cutter 13.In the region of the insertion station in downstream, from packaging
Cigarette packages 11 and then all fold the multiple of rotating turret 14 with being pushed into each case that unit (not shown) comes out
The single film blank in a bag in bag links.Packaging unit, folding rotating turret, as the miscellaneous equipment of packing machine 10,
It is widely known in the prior art, packaging unit is no longer more fully described herein and rotating turret is folded.In addition, according to this
Invention, the particular configuration of packing machine in itself and the type (being in this case film) of the material of used web shape only have very
Few association.
The packaging material (that is, expire web 16) of the current web shape used in packing processes is rolled up in this case
It is wound on the first spool (that is, expire spool 15), the packaging material is unwind from first spool.Expire the arriving of the downstream of spool 15
Phase web 16 is directed along web of material accumulator 17 (that is, ring case), and passes through a pair of indexable quilts of (indexing) roller 18
It is sent to unification station.
The spool 15 that expires is rested upon on spool recipient 15a, correspondingly, and the spool recipient can be driven by servomotor
Move or driven during operation by servomotor.During the operation of packing machine 10, servomotor is with corresponding to expired web
16 accordingly along direction of rotation or the required web speed of unreeling direction angular velocity of rotation driving expire spool 15 or
Corresponding spool recipient 15a is driven, as shown in Figure 1.
The spool 15 that expires is a part for spool switching device 19.The capital equipment of the spool switching device and general operation
Pattern has been known in the prior art.
Another spool (particularly, new spool or displacement spool 20) is arranged in spool switching device 19, so as to expiring
Spool 15 is spaced apart.The new spool 20 to be rested upon with the identical mode of spool 15 that expires on specified spool recipient 20a,
Correspondingly, the spool recipient is same is driven or can be driven by servomotor by servomotor.It is used as new web 21
(film) web material is with whole amounts or with all amounts of abundance under any circumstance on new spool 20 so that expiring
Web 16 replaces the spool 15 that expires in the case of being finished by new spool 20.Therefore, new spool 20 plays the web 16 that once expires
It has been depleted just to provide new web material for packaging process, the work of new web material is particularly provided in unbroken mode
With.
For this purpose, especially can be configured to that web speed can also be not being reduced according to the spool switching device 19 of the present invention
The web 16 that makes to expire in the case of degree is connected to new web 21.However, in the case of the present invention, naturally also can be with reduction
Web speed carrys out switching spool.
, correspondingly will be new for the connection procedure, it is important that before the actual connection of web 16,21 is performed
Web 21 or the initial web speed that at least a portion of new web 21 is accelerated to the web 16 that expires.
According to the present invention, for fault-free and the connection procedure of optimization, new volume is initially determined that in an automated way
(initial) diameter (diameter for including the new web 21 on new spool 20) of axle 20.Perform the step of the determination initial diameter
Suddenly so as to especially perform connection procedure in the accurate mode in position.In addition, automatically determining initial diameter causes have not
The various new spools 20 (such as half-full spool etc.) of same initial diameter can be used in packaging process.
In order to determine in an automated way diameter there is provided, before new spool 20 is connected to the web 16 that expires, with
Targeted manner accelerates new spool in boost phase, and is measured as during boost phase the motor electricity of the servomotor needed for this
Stream.
In the present example embodiment, accelerate (in a constant manner) along the specific anglec of rotation or displacement angle α
New spool 20, and measure for the servomotor electric current needed for the acceleration.In this case, current value herein is also recorded,
Referring to Fig. 3.Then, recorded current curve is assessed to determine diameter.
The assessment can be mathematically performed, such as, using corresponding computer installation, the computer installation can be such as
It is for controlling a part for the control unit of spool switching device, a part for servomotor controller or host computer control
A part for device processed.But, alternately, it is also contemplated that, for example, specific motor current value or motor current curve
Correspondingly it is associated with the diameter value being established empirically, or the contact is stored in database.According to measured motor
Current value, then can retrieve corresponding storage diameter from database.
In the case where mathematics as described above is established, the diameter Da of new spool 20 then can be from the current of electric detected
Value, in combination with given parameter and constant value (torque constant of such as servomotor), using those skilled in the art widely
Well known simple association is determined.
Fig. 6 shows various curve maps into Fig. 8, and by the curve map, some associations having already mentioned above will
Explain in further detail below.
In figure 6, in an illustrative manner, the angular acceleration set on servomotorIt is shown in above anglec of rotation α,
The axle of the servomotor of new spool 20 is driven to rotate the anglec of rotation α in a targeted way.In the present example embodiment, servo
Motor and corresponding new spool 20 are for determining that the boost phase of diameter accelerates in a constant manner, if from Fig. 6
Straight line 22 it is visible as.Although must be not necessarily such case.
Delineate in an exemplary fashion in the figure 7 for big reel diameter (referring to straight line 23a), for medium spool
Diameter (referring to straight line 23b) and the corresponding current value I for small reel diameter (referring to straight line 23c), the current value I according to
Caused by anglec of rotation α.It can be readily seen that higher servomotor current value must be applied to correspondingly with medium volume
The reel diameter of shaft diameter or smaller compares bigger reel diameter.
Figure 8 illustrates the pass between the current value I applied and corresponding reel diameter Da for certain material
Connection.Curve M1、M2、M3Represent to represent the various material M on corresponding new spool 20 respectively1、M2、M3Depend on electric current
Diameter value.
It can be seen that, the current value I specifically measured1In material M1In the case of will imply that than in material M3In the case of more
Big diameter.Because material M3With lower density, and corresponding new spool 20 is generally than material M1With lower
Mass inertia.
It can draw in addition, in the case of given material, such as the material M in Fig. 81In the case of, exist respectively
The different size of diameter D of spool1、D2Or D3In the case of measure corresponding different size of electric current I1、I2Or I3, such as
As seeing in the figure 7.Here, D1Represent major diameter, D2Represent intermediate diameter, D3Represent minor diameter.As can be understood that
Sample, bigger diameter needs higher servomotor electric current, so as to set corresponding larger spool in desired rotation
Weight.
Also allowed the web of material ring of limit length according to the determination of the diameter of the corresponding new rotating shaft 20 of the present invention
Δ is automatically set to the material accumulator for connection procedure itself, referring to Fig. 5.Select ring Δ in a particular manner herein
Ring length, especially so that the linkage section 24 of new web 21 can be accelerated to web speed, and long for the web needed for this
Degree is directly fed from ring Δ, without the applying power on new spool 21.
In order to limit web of material ring Δ to be supplied, new spool 20 rotates initially along coiling direction, referring to Fig. 4.
During the rotation, the preceding holding part unwind from new spool 20 of new web 21 is kept component (not shown) and tightly protected
Hold so that new web 21 is stretched between holding part and new spool 20.For example, it is predetermined until having reached to perform winding
Torque is tensioned, the tensioning torque can in known manner be measured during tensioning process.
In this case, holding part is formed by connection (end) section 24 of new web 21, and the linkage section is finally connected
To the web 16 that expires.But, this is not compulsory.
, in the next step, can be by making spool 20 anti-along unreeling direction since the tensioning state of new web 21
Driving is performed in a targeted way to rotation, to obtain predetermined ring length.Can easily (mathematics) be defined as this must
The corresponding required rotation of palpus or displacement angle α, because the diameter of new spool 21 is had determined that before this, referring to upper
Text.
As already noted, ring length here is chosen to accelerate roller 25a that (it passes through rotation, particularly revolved
Turn 180 ° and linkage section 24 accelerated to the web speed of the web 16 that expires) directly fetched from ring Δ it is long for the web needed for this
Degree so that no power is applied on new spool 21 herein.In other words, ring length is chosen to extract out from new spool 21
Other material for accelerating linkage section 24.After all, this will be destructive, because the inertia of new spool 20 will cause new width
The corresponding undesirable tensioning of material 21 or undesirable stretching.
During acceleration or and then after, linkage section 24 leads in mode well known in the prior art, for example
Cross adhesive tape and be connected to the web 16 that expires.
