Description
Technical field
The present invention relates to a kind of according to described in claim 1 and 12 for the method running shrinking tunnel.Particularly, the present invention relates to a kind of method making shrinking tunnel be transformed into production model and a kind of method making shrinking tunnel be transformed into shutdown mode from production model.
Background technology
It is known that wrap up object, particularly bottle, tank, beverage can or the like by film and then transported through shrinking tunnel in fill and packaging facilities.In beverage industry, preferably refer to so-called multi-pack with the article of film parcel.Film refers to heat shrink films in this case, also serves as LDPE, LLEPE-plastic foil and is familiar with by technical staff.The object that wraps up with such film thus wrap up in packer at it be followed by pumped through shrinking tunnel, and be loaded hot-air there, thus film shrink and clings on object.The cooled region with fan being connected directly between on shrinking tunnel is responsible for cooling down multi-pack rapidly, and thus these multi-pack obtain its intensity that can transmit.
Such shrinking tunnel is substantially made up of the continuous conveying mechanism of cincture now, and this continuous conveying mechanism adds in segmentation and is stamped enclosing (tunnel), and this enclosing forms tunnel.Additionally, shrinking tunnel is mostly by multiple heating element heaters and also fan or aerator are constituted, in order to hot-air needed for generation and then hot-air being distributed in tunnel inner chamber.In order to realize disperseing the most uniformly of hot-air, hot-air is partly directed to the neutralization of so-called well bore wall by suitable hot-air guide portion after it produces and is partly directed in the chamber being located immediately at below the conveying mechanism of shrinking tunnel.Therefore, multi-pack is preferably loaded hot-air on one's own initiative from least three sides.The essential structure of shrinking tunnel is explained the most roughly herein.Technical staff from packaging industry knows the structure of such shrinking tunnel, thus need not carry out further details description herein.
As illustrated in beginning, such shrinking tunnel needs the gaseous medium (being hot-air mostly) of heat to make film shrink.This hot-air is produced by the heating arrangements being shrinking tunnel ingredient.The hot-air that produced hot-air is produced by heating arrangements in other words produces preferably by electric energy at this.During this period, people also then produce required hot-air by the most so-called gas burner.Unfortunately, required gas can not utilize without any problems in a lot of places, uses back the most again electrically heated shrinking tunnel.
Such electrically heated shrinking tunnel has big demand for electric energy, thus creates significant cost for operator.Particularly, the generation of hot-air is maximum energy consumption device in shrinking tunnel.Now it was determined that the power consumption in shrinking tunnel can reduce in the following way, i.e. in shrinking tunnel is without some running status for producing or operational mode, this shrinking tunnel is placed in so-called standby mode.Reduce the power of one or more customers of shrinking tunnel at this and therefore reduce energy expenditure relative to production run.
Such shrinking tunnel or such method for making shrinking tunnel run are such as known by DE 102,010 011 640 A1.Being described herein a kind of shrinking tunnel, this shrinking tunnel also has other so-called standby mode in addition to conventional production model, wherein makes shrinking tunnel run with the power reduced relative to production model by this standby mode.Conversion between conventional production model and other standby mode is controlled by time and/or signal at this.When being transformed into standby mode, taking some measures at this, these measures reduce the energy requirement of shrinking tunnel.One measure e.g., can be adjusted to exist relative on the backup temperature reduced to fixed temperature to fixed temperature, and the heating power that result is required is less.Another measure e.g. reduces the transfer rate of the conveyer of shrinking tunnel side, in order to makes to discharge (heat discharge in other words) from the energy in tunnel and minimizes.Knowing again, the cooling cutting off the conveyer of shrinking tunnel side and the multi-pack also having cooling to remove from shrinking tunnel are also the measures for reducing energy requirement.If each Close Tunnel is equipped with the aerator that at least two electricity runs, the energy requirement that the cut-out of the aerator of the heating arrangements of the most each Close Tunnel can reduce.
It is furthermore well known that so-called standby mode brings another measure, wherein two openings in the input area and output area of shrinking tunnel are closed at least in part.Shrinking tunnel input area and shrinking tunnel output area are logically so opened to degree in conventional production model so that multi-pack can pass in and out shrinking tunnel without hindrance.Shrinking tunnel input area and shrinking tunnel output area at this between corresponding operational mode (that is between production model and standby mode) conversion time or open or close.Conversion between the two operational mode is triggered by time and/or signal equally at this with controlling.This control device for running shrinking tunnel and this shrinking tunnel itself are such as learnt by DE 10 2,010 020 957 A1.
Therefore above-mentioned prior art has been disclosed for a kind of shrinking tunnel or a kind of method for controlling shrinking tunnel, and it is changed by time and/or signal between two operational modes with controlling, and produces different energy requirements in the two operational mode respectively.Additionally, the document discloses a kind of shrinking tunnel or a kind of method for controlling shrinking tunnel, this shrinking tunnel opens or is enclosed in the shrinking tunnel opening in the input of shrinking tunnel and output area extraly between two operational modes during conversion.
Summary of the invention
The purpose of the present invention is now; so optimize the prior art proposed, optimize i.e. further and particularly minimize energy requirement when shrinking tunnel switches in shutdown mode (such as in standby mode) in other words between production model and shutdown mode (such as standby mode).
Described purpose by a kind of according to described in claim 1 and/or 12, realize for the method that makes shrinking tunnel be transformed into production model and the method for making shrinking tunnel be transformed into shutdown mode from production model.
Have shown that, after changing between by each operational mode known in the art with being controlled by time and/or signal, following result is caused for operation or for controlling the sequence of steps of the restriction of indivedual measures first mentioned of shrinking tunnel, i.e., directly upon the transition until the preset value reaching corresponding operational mode just can reduce energy requirement the most further.
Therefore, the present invention points out a kind of first method for making the shrinking tunnel with conveying mechanism be transformed into production model, and the method at least includes opening shrinking tunnel input area and/or opening shrinking tunnel output area.The method particularly can relate to putting into operation first or shrinking tunnel conversion from standby mode to production model of shrinking tunnel.In addition shrinking tunnel can be made to be transformed in production model, be thus in so-called stop mode owing to alreadying switch off all energy consumption devices and this shrinking tunnel longer downtime in this shrinking tunnel.Important difference between standby mode and stop mode is, shrinking tunnel in standby mode as being maintained at relatively low second on fixed temperature as known in the art.By switching all energy consumption devices in stop mode, the inside of shrinking tunnel can cool down according to persistent period of downtime until ambient temperature.If shrinking tunnel should be risen to production model again, do not know the tunnel temperature of reality the most in advance.
Described method includes at least one following step: a) cavity temperature in shrinking tunnel is brought up to predetermined set-point；B) connect conveying mechanism or the speed of conveying mechanism is brought up to predetermined set-point；C) chain is cooled down power and bring up to predetermined set-point with coolconveyer structure；D) multi-pack is cooled down power and bring up to predetermined set-point.According to the present invention, shrinking tunnel input area open and/or shrinking tunnel output area open the earliest with step a), one of b), c) and/or d) together with carry out.Preferably, each set-point has referred to production value.
Should inquire into the most in detail herein for the ingredient according to the shrinking tunnel needed for the method for the present invention, these ingredients in process after a while for being important according to the method for the present invention.
For according to the method for the present invention, the shrinking tunnel according to the present invention is made up of ingredient the most described below at this.Such shrinking tunnel has the unit (such as with fan, heating monitor, the hot air blowers of forms of sensor) of motor-driven conveying mechanism and one or more also combinations, these units produce for required hot-air and are therefore required for the regulation of cavity temperature in shrinking tunnel, correspondingly in order to reach predetermined set-point such as with DEG C temperature represented.Particularly, can be provided with sensor in the inner chamber of shrinking tunnel, these sensors are tried to achieve actual temperature and continue to be sent to control unit by value.Actual temperature is compared with to fixed temperature, and to hot air blowers and/or heating monitor regulate the most again, thus regulate in shrinking tunnel inner chamber to fixed temperature.In addition, for there is so-called current source chiller according to the shrinking tunnel according to the present invention of the method for the present invention, this current source chiller is such as made up of, outside these units are arranged on tunnel inner chamber, preferably below the conveying mechanism of cincture the unit (such as fan and sensor if desired) of one or more also combinations.Cooling unit is for coolconveyer structure, this conveying mechanism e.g. mesh grille band chain or so-called rod roller chain.Conveying mechanism is heated when delivery tunnel is run continuously.Before it is again through shrinking tunnel, it must cool down, because the article otherwise existing for package media and/or subsequent delivery at least partly melt and adhere to danger on the conveyor when returning.In addition, for having the unit (such as axial fan or cross flow fan) of at least one or more also combinations according to the shrinking tunnel according to the present invention of the method for the present invention, after these units are set directly at shrinking tunnel inner chamber mostly, that is be arranged on outside conveying mechanism and on and/or side, they are for the cooling of multi-pack and be necessary thus for required cooling power.In addition, method according to the present invention is specified, door or other suitable closure elements it is provided with in the region of two tunnel openings of the shrinking tunnel according to the present invention, described door or closure elements are automatically switched off when needed or open, and wherein reduce the heat from shrinking tunnel under the closed mode of door or closure elements and discharge.In order to make all customers mentioned in a limiting fashion with method, particularly with limit sequence of steps run, shrinking tunnel also includes the control device of oneself, can implement the method according to the present invention by this control device.In this control device, storage has data required for according to the method for the present invention.Preferably, also it is equipped with at least one sensing mechanism (such as grating) and the discharge side in tunnel is equipped with at least one other sensing mechanism (such as grating) at the approaching side in tunnel according to the shrinking tunnel needed for the method for the present invention.Additionally, for according to the method for the present invention it is essential that the control unit of oneself of shrinking tunnel has to the packer being set directly at before shrinking tunnel or to the interface of control unit of packer, and these interfaces can mutually communication.The communication interface of the packer for making shrinking tunnel and be arranged on above such as can be carried out via so-called Ethernet at this.
Because on the one hand each single measure step in other words required for the operation according to the present invention of shrinking tunnel requires different energy requirements, and on the other hand according to the time that specific parameter request is different, so advantageously, these single measure or steps are introduced in a defined sequence.
By the order of the restriction of each single step, can again reduce the energy requirement during specific measure.With production model and standby mode as starting point, each pattern in the two operational mode is therefore it is first necessary to carry out some also based on the set-point limited as the step of preset value.In order to reach these set-points, therefore along with every time opening specific measure or step to the conversion of another operational mode from an operational mode.It has been shown that when each step or measure perform in a defined sequence, can again reduce the energy requirement during indivedual or multiple steps are implemented by the order of this restriction.
The most conclusive, when perform single step or multiple step, and how long the persistent period of a step or multiple step is, in order to perform this step completely
Method according to the present invention should be described and according to other embodiments of method of the present invention or further improvement project according to detailed description below.
At least include at this opening shrinking tunnel input area and/or opening shrinking tunnel output area according to the method (shrinking tunnel should be made in the method to be transformed into production model) being used for running shrinking tunnel of the present invention.When shrinking tunnel is initially located in standby mode also or when shrinking tunnel is in stop mode with completely cutting through in advance, as its such as situation when putting into operation first, then use this method.Additionally, the most at least include according to the method for the present invention: cavity temperature in shrinking tunnel is brought up to predetermined set-point by step a)；And/or step b) connects conveying mechanism or the speed of conveying mechanism is brought up to predetermined set-point；And/or chain is cooled down power and brings up to predetermined set-point by step c)；And/or multi-pack is cooled down power and brings up to predetermined set-point by step d).Due to shrinking tunnel input area open and/or opening of shrinking tunnel output area is carried out, so reducing the energy requirement of the method according to the present invention together with one of d) with above-mentioned steps a) the earliest.
Advise according to the another kind of method flexible program of the present invention, shrinking tunnel input area and/or shrinking tunnel output area open with step a) to one of d) carry out simultaneously or the latest step a), one of b), c) and/or d) after carry out.
The most particularly advantageously, use a kind of method for running shrinking tunnel, wherein, shrinking tunnel input area open and/or shrinking tunnel output area open in shrinking tunnel cavity temperature reach to carry out during above-mentioned predetermined set-point.Therefore during the heating process of shrinking tunnel inner chamber, it is by the unit (realization) of the consumed energy of multiple electric power, individually or also combinations, original text is imperfect), prevent shrinking tunnel input area and/or shrinking tunnel output area from opening in advance.Therefore the unit (such as heat monitor, heater blower, aerator) required for heating process can run as efficiently as possible, because shrinking tunnel input area and/or shrinking tunnel output area are in the state of closedown.If closed in two the shrinking tunnel inputs of heating process period and output area, then the persistent period of heating process the most also shortens, and particularly shortens step a) and cavity temperature in shrinking tunnel brings up to the persistent period of predetermined set-point.During by the predetermined set-point that reached cavity temperature in shrinking tunnel in step a), by opening shrinking tunnel input area and/or shrinking tunnel output area the earliest, can reduce the duration of heat and make thermal loss minimize in addition, the energy requirement thus reducing the thus obtained accumulation for step a) reduces.In addition by opening shrinking tunnel input area and shrinking tunnel output area the earliest, this is only just carried out when reaching the set-point of step a), owing to shortening the duration of heat, so shortening the preparation persistent period for producing required given state of shrinking tunnel.
In the special embodiment of another kind, step " opening of shrinking tunnel input area and/or opening of shrinking tunnel output area " is carried out owing to cavity temperature in shrinking tunnel is brought up to the continuation of predetermined set-point by step a).Therefore to reaching the formation accumulation of heat not long ago prevented in shrinking tunnel inner chamber of the predetermined set-point of cavity temperature in shrinking tunnel, shrinking tunnel input area open and/or opening of shrinking tunnel output area just can be carried out when reaching predetermined temperature (it is less than the set-point for production model).Thus avoid the possible accumulation of heat within shrinking tunnel to be formed, it is overheated that this accumulation of heat forms the first multi-pack that may cause being carried by shrinking tunnel.In other words, due to reach limit to fixed temperature time open shrinking tunnel input area and/or open shrinking tunnel output area, should be such as suitable with the 90 95% of the predetermined set-point of shrinking tunnel internal temperature to fixed temperature, the accumulation of heat within shrinking tunnel can be avoided to be formed, thus in step a) is by shrinking tunnel cavity temperature bring up to the first multi-pack that predetermined set-point completes to be pumped through afterwards will not be overheated or damage.This improves the quality of the first multi-pack processed in shrinking tunnel, and otherwise these multi-pack may must be dropped.
According to the another kind of particularly embodiment regulation of the method for the present invention, predetermined to fixed temperature by continuing shrinking tunnel to be heated to, perform step b) that is connect conveying mechanism or the speed of conveying mechanism brought up to predetermined to fixed temperature.Such as it can be stated that when the temperature in shrinking tunnel inner chamber approximately reaches the 90% of set-point, just connect conveying mechanism.Conveying mechanism needs also exist for specifically to fixed temperature for production model.If conveying mechanism is supercool, then the quality of the contractive effect in this negatively affects multi-pack bottom section.If cutting off conveying mechanism in standby mode, then when shrinking tunnel inner chamber heats, the most only transit area within shrinking tunnel is heated.And the return area of conveying mechanism keeps being cold according to arrangement.Connect moment of conveying mechanism improve in other words conveying mechanism speed time be engraved in this and so select, during making when passing through shrinking tunnel the time needed for the final set-point for shrinking tunnel is heated to required shrinking tunnel internal temperature, all regions of conveying mechanism are sufficiently heated, thus this conveying mechanism is heated to required production temperature all sidedly.
Simultaneously may be it is necessary that connect chain cooling body or improve chain cooling power, in order to the temperature of conveying mechanism, particularly in shrinking tunnel tunnel input area, there is desired temperature.
Therefore specify according to the another kind of particularly embodiment of the method for the present invention, according to the chain temperature tried to achieve, chain is cooled down power and bring up to predetermined set-point.In shrinking tunnel in normal production model coolconveyer structure (such as mesh grille band chain link, rod roller chain) constantly, in order to prevent this conveying mechanism to be heated too strongly.The too strong conveying mechanism being heated will cause package media to melt and also may will cause the partial melting of article.This causes conveying mechanism to be polluted by plastic residue and hinders the transmission of continuation.Additionally, this may affect the quality of the multi-pack shunk significantly.Method now according to the present invention specifies, except the earliest with step a), one of b), c) or d) together with the opening and/or in addition to the opening of shrinking tunnel output area of shrinking tunnel input area that carry out, during step c) that is at raising cooling power during coolconveyer structure, improve chain cooling power according to the conveying mechanism temperature tried to achieve.Improving chain cooling power according to the conveying mechanism temperature tried to achieve, this cooling power is only when also really the most just improving.Therefore energy expenditure can be reduced targetedly and the most further.The temperature of conveying mechanism is particularly tried to achieve by the sensor-type measurement of temperature in delivery tunnel output area or after being connected on shrinking tunnel output area and it is compared with predetermined set-point.The temperature value that this set-point should have in shrinking tunnel input area with conveying mechanism is suitable.When conveying mechanism returns between shrinking tunnel output area and shrinking tunnel input area, suitably coolconveyer structure.The effect of cooling can be checked by the second temperature sensor being arranged in return area and again matched chain can cool down power if desired.
In addition it has been shown that significant it may be that shrinking tunnel door or closure elements are opened not only according to shrinking tunnel internal temperature, and according to being produced by the packer being arranged on upstream and being opened by the multi-pack of shrinking tunnel via conveying mechanism conveying.The most equally avoid the energy loss caused owing to opening shrinking tunnel door or closure elements too early.The most such as can utilize the following time when packer starts, packer utilizes this time to be wrapped up by the first multi-pack film and then transferring to shrinking tunnel.This time is not small.Restarting of each step of performing due to packer and first having to (forming body as each single article being arranged to multi-pack, multi-pack is formed body continue transported in film packaging module, form body by contractile film parcel multi-pack, the film multi-pack wrapped up is exported and transfers to conveying mechanism), take the regular hour, until in order to the production task (i.e. shrinking multi-pack) of its routine needs this shrinking tunnel.It is contemplated that shrinking tunnel input area is only just opened when packer has begun to and manufactures film multi-pack and parcel thereof.It is particularly preferred that shrinking tunnel input area is just opened along with the making of the first multi-pack wrapped up by shrink film.Shrink tunnel tunnel output area can open at identical conditions, also or only when the regular hour was passed in realization according to the speed of conveying mechanism just open.Making and transmission on the conveyor according to wrapped film multi-pack, and the known transporting velocity according to conveying mechanism, can highly precisely try to achieve, and the transmission of the first multi-pack needs how long to arrive at shrinking tunnel output area.Therefore shrinking tunnel output area was opened before multi-pack reaches it in time.
Another kind also allows for more effectively controlling shrinking tunnel door and to need not the special ways and means of complicated program work be that shrinking tunnel input area and shrinking tunnel output area are respectively provided with the sensing mechanism of oneself.The design of sensing mechanism was at least provided with the first grating before shrinking tunnel input area at this.According to the time interval taking and subscribing, what this grating device controlled two shrinking tunnel doors opens the moment, and wherein shrinking tunnel input area is first turned on and shrinking tunnel output area was just opened after in the past in predetermined time interval then.Alternatively, shrinking tunnel output area can also opening and open simultaneously with shrinking tunnel input area.This control mode of opening of two shrinking tunnel doors or closure elements looks like particularly preferred, and it is the simplest and the most direct ways and means simultaneously, to open shrinking tunnel door or closure elements as accurately as possible, when this is required, say, that when when multi-pack enters in shrinking tunnel or is positioned at the defeated foremost such as region of shrinking tunnel or being positioned at the foremost of shrinking tunnel output area when multi-pack at shrinking tunnel.
At edge it should be noted that shrinking tunnel door may also be used for as directly as possible and be rapidly closed shrinking tunnel input area and shrinking tunnel output area via this ways and means that grating device controls.For this it can be stated that and be directly respectively arranged with grating after shrinking tunnel output area before shrinking tunnel input area.
This external shrinking tunnel starts or completely when the activation measure that resting state rises to production model, and conveying mechanism can run with the transfer rate improved prior to or just when the first multi-pack transfers to conveying mechanism in short time.This additional method step only indirectly contributes to optimizing energy requirement or energy expenditure.Only along with or only the most just the activating and open portal, owing to the door closed before forms so-called accumulation of heat in shrinking tunnel of the required given running temperature in reaching shrinking tunnel inner chamber.If now the first multi-pack directly being opened at door and being sent into shrinking tunnel afterwards or through shrinking tunnel, the then accumulation of heat that these first multi-pack are improved before.This may cause, and the first multi-pack being sent in shrinking tunnel may be applied in too much heat.For this reason may be it is necessary that after shrinking tunnel door then turns on, the transfer rate of conveying mechanism be at short notice higher than the conventional transfer rate required for normal production run.From the point of view of the most proportionally, owing to improve transfer rate at short notice, the heat identical with in other multi-pack follow-up is applied in the first multi-pack of traveling, and these other multi-pack follow-up are pumped through shrinking tunnel with normal transfer rate under normal working condition.In order to here understand fully which is to be transmitted through the first multi-pack of shrinking tunnel with the transfer rate improved and which is the follow-up multi-pack being moved through shrinking tunnel under normal working condition, it is to be noted herein that the first multi-pack includes at least five multi-pack but the amount of maximum 25 multi-pack.If people also to make other multi-pack carry by shrinking tunnel with the transfer rate improved, then lack, due to accumulation of heat, the contraction structure that can ensure to optimize the most again.The short-term raising of transfer rate can define about 1 to 3 minute in time.
As already has been said, shrinking tunnel may be in stop mode, and in this stop mode, all energy consumption devices completely cut through.Also or shrinking tunnel is in standby mode, in this standby mode, the power of energy consumption device reduces at least in part.Part energy customer (the most a part of heating arrangements) can also completely cut through at this.Shrinking tunnel substantially can be made relatively quickly to back within production model from standby mode.And all energy consumption devices cut off in stop mode, thus shrinking tunnel even can be cooled to room temperature according to the persistent period of downtime.Particularly, by control unit being placed in stop mode at all method step a) of enforcement after e), introduce the stop mode of shrinking tunnel, thus cut off all energy consumption devices.In order to shrinking tunnel is replaced in production model, therefore can specify that in other method step f), first control unit and shrinking tunnel being waken up up from stop mode and make it be transformed in so-called operational mode, in this operational mode, all heating arrangements of such as shrinking tunnel are with maximum Power operation.If then reach substantially with the given internal temperature in standby mode or the shrinking tunnel internal temperature suitable with about 85 to 90% of the given internal temperature in standby mode, the power and the unlatching that the most again reduce heating arrangements make shrinking tunnel be transformed into the method step of production model from standby mode.
The invention still further relates to a kind of method for making shrinking tunnel be transformed into production model, wherein said method at least includes opening shrinking tunnel input area and/or opening shrinking tunnel output area.Here specifying, shrinking tunnel input area and the shrinking tunnel output area of shrinking tunnel are first in closed state.First shrinking tunnel is transformed in operational mode.The power of this at least one customer by connecting or within rising shrinking tunnel is carried out.Shrinking tunnel input area open and/or opening of shrinking tunnel output area is carried out with the power-on or raise of at least one customer described within shrinking tunnel the earliest.Particularly specify, shrinking tunnel input area open and/or opening of shrinking tunnel output area is only just carried out when the minimum temperature reached in shrinking tunnel inner chamber.This such as checks via the temperature sensor coupled with control unit and controls.Then bring up to the power of other customers produce power, thus regulate the production model of shrinking tunnel.
The invention still further relates to a kind of method for making shrinking tunnel be transformed into shutdown mode from production model.Shutdown mode can be understood as following standby mode, and in this standby mode, shrinking tunnel is with the Power operation reduced.But standby mode is it also will be understood that become following stop mode, in this stop mode, all energy consumption devices of shrinking tunnel completely cut through.This method at least includes closing shrinking tunnel input area and/or closing shrinking tunnel output area.Additionally, this method includes at least one following step: aa) shrinking tunnel internal temperature is reduced to predetermined set-point；Bb) speed of conveying mechanism is reduced to predetermined set-point；Cc) chain is cooled down power and be reduced to predetermined set-point；Dd) multi-pack is cooled down power and be reduced to predetermined set-point.According to present invention provide that, the closedown of shrinking tunnel input area and/or the closedown of shrinking tunnel output area the latest with step aa), bb), cc) or one of dd) together with carry out.
In addition it can be stated that the closedown of the closedown of shrinking tunnel input area and/or shrinking tunnel output area is as far back as step aa), bb), cc) or one of dd) before carry out.It is particularly preferred that the closedown of the closedown of shrinking tunnel input area and/or shrinking tunnel output area as first step in step aa), bb), cc) or one of dd) before perform.Particularly, step aa), bb), cc) or dd) can carry out in the same manner by arbitrary order or time.
According to one embodiment of the present invention, the reduction of the speed of conveying mechanism is carried out along with the reduction of shrinking tunnel internal temperature the latest.By the persistent movement of conveying mechanism, always it is to ensure that when shrinking tunnel is heated, is not to supply heat to conveying mechanism continuously.In return area, particularly there is no heat supply, thus conveying mechanism always can cool down the most partly.If the transfer rate of conveying mechanism temperature in shrinking tunnel inner chamber before reducing the most decreased or conveying mechanism stop completely, the the most overheated of conveying mechanism then may occur partly in shrinking tunnel inner chamber, and this is likely to cause to damage other ingredients within conveying mechanism or shrinking tunnel.As already has been said, conveying mechanism generally also must cool down for this reason in normal production run, in order to avoids the overheated of conveying mechanism and the damage to the multi-pack processed thus caused.
According to one embodiment of the present invention, the reduction of chain cooling power is carried out the latest together with the reduction of conveying mechanism speed.Obtaining in conjunction with above said content, the reduction of the reduction of shrinking tunnel internal temperature, the reduction of conveying mechanism transfer rate and chain cooling power is preferably simultaneously carried out.
In addition present invention additionally comprises additional step ee), utilize this step try to achieve the position of the multi-pack carried on the conveyor and close shrinking tunnel input area and/or shrinking tunnel output area according to the position tried to achieve.
If should perform, for making shrinking tunnel method from production model conversion shutdown mode, the most pending multi-pack to be supplied to shrinking tunnel.But, multi-pack should not had during shutdown mode to stay in shrinking tunnel.Therefore, shrinking tunnel input area can have been closed after last multi-pack enters in shrinking tunnel, and shrinking tunnel output area can only just be closed when the already out shrinking tunnel of last multi-pack.But because being likely to be formed accumulation of heat in this case, so preferably two regions are closed after the most already out shrinking tunnel of all multi-pack simultaneously.
Can also specify when the longest downtime in other embodiments, method step aa), bb), cc) and/or each set-point dd) equal to zero.Particularly specify in so-called stop mode, cut off all energy consumption devices of shrinking tunnel.Shrinking tunnel internal temperature can not also be monitored in this case, thus this shrinking tunnel can be cooled to substantially suitable with the ambient temperature existed temperature in the limiting case.
Particularly, implementing institute aa in steps the latest) to ee) after can specify that another step ff), the control unit of shrinking tunnel is placed in stop mode by this step added.Aa in steps) to ee) and enforcement especially mean that longer downtime, and accordingly act as the signal for control unit to completely cut through all energy consumption devices.

Detailed description of the invention
Identical for the present invention or phase same-action element employs identical reference.The most for the sake of clarity, reference required for the explanation of respective drawings is the most only shown.Shown embodiment is only how can to design the example of the method according to the invention and not constitute enclosed restriction.
Fig. 1 illustrates for making shrinking tunnel be transformed into the schematic overview of the method in different operational mode.In production model PM, shrinking tunnel substantially has the internal temperature Ti-PM for the normal restriction shunk needed for running.This internal temperature is less than packaging material and the fusion temperature of article.Such as, internal temperature Ti-PM is about 200 DEG C in production model PM.Carry the article utilizing package media to wrap up or article are collected body and moved with predetermined speed of production V (F)-PM by the conveying mechanism of shrinking tunnel.Conveying mechanism particularly relates to the continuous conveying mechanism moved continuously.This conveying mechanism cools down the most again via the first aerator or other the first coolant feeders when heating up when passing through shrinking tunnel and return between shrinking tunnel input area and shrinking tunnel output area.In production model, the first coolant feeder is with cooling power P (F)-PM work.Additionally, multi-pack cools down by the second aerator or other the second coolant feeders after leaving shrinking tunnel, then they are supplied to other processing unit (plant)s.In production model PM, the second coolant feeder is with cooling power P (G)-PM work.
In order to reduce by the energy requirement producing or keeping in repair during the downtime caused, shrinking tunnel can be placed in the first standby mode SB.Particularly, following measures is performed individually or in any combination.
Aa) shrinking tunnel internal temperature is reduced to predetermined set-point Ti-SB, under this set-point such as shrinking tunnel internal temperature Ti-PM in production model such as between 50 DEG C to 80 DEG C.
Bb) additionally, the speed of conveying mechanism is reduced to predetermined set-point V (F)-SB, this set-point is less than speed V (the F)-PM of conveying mechanism in production run in other words production model PM.
Cc) chain cooling down power and is reduced to predetermined set-point P (F)-SB, this set-point is less than chain cooling power P (the F)-PM in production run in other words production model PM.
Dd) multi-pack cooling down power and is reduced to predetermined set-point P (G)-SB, this set-point is less than multi-pack cooling power P (the G)-PM in production run in other words production model PM.
Additionally, shrinking tunnel input area and shrinking tunnel output area the latest with step aa), bb), cc) or one of dd) together with closed by door or other suitable closure elements.
Preferably, at method step ee) in try to achieve the position of the multi-pack carried on the conveyor.The closedown of shrinking tunnel input area and/or shrinking tunnel output area is carried out according to the position of the multi-pack tried to achieve.Particularly, only when when there is no multi-pack in the entrance region of shrinking tunnel, just closing shrinking tunnel input area.Additionally, only when no longer having multi-pack inside shrinking tunnel, just close shrinking tunnel output area.
When shrinking tunnel reaches standby mode SB, particularly just can be at method step ff when longer downtime) in control unit is placed in stop mode.Thus start completely cut through all energy consumption devices of shrinking tunnel and shrinking tunnel is placed in stop mode S.In stop mode S, method step aa) to dd) set-point suitable with null value respectively.Particularly cut off heating arrangements, thus the inner chamber of shrinking tunnel cools down uncontrollably and is substantially matched to ambient temperature RT according to the persistent period of downtime.Additionally, completely cut through conveying mechanism itself and chain cooling body and multi-pack cooling body.
In order to make shrinking tunnel again be transformed into production model PM from standby mode SB, following measure is performed individually or in any combination:
A) shrinking tunnel internal temperature is heated to the predetermined set-point of the shrinking tunnel internal temperature Ti-PM for production model PM.
B) speed of conveying mechanism is brought up to speed V (the F)-PM of conveying mechanism in production run.
C) chain is cooled down chain cooling power P (the F)-PM that power brings up in production run.
D) multi-pack is cooled down multi-pack cooling power P (the G)-PM that power brings up in production run.
Additionally, by the door in shrinking tunnel input area and in shrinking tunnel output area or closure elements the latest with step a), one of b), c) or d) together with open.
In order to make shrinking tunnel again be transformed into production model PM from stop mode S, substantially there are two kinds of probabilities.When the first probability, control unit is converted to activation pattern from stop mode.Each energy consumption device of shrinking tunnel is connected at least in part at this, thus shrinking tunnel is placed in standby mode, this standby mode has multi-pack cooling power P (the G)-SB of speed V (the F)-SB of the conveying mechanism of the shrinking tunnel internal temperature Ti-SB of restriction, reduction, chain cooling power P (the F)-SB of reduction and/or reduction.Then tunnel power is made finally to be matched with production model PM and the input opening shrinking tunnel and/or output area.
It is alternatively possible to control unit is converted to operational mode from stop mode.This is for setting up production model PM of shrinking tunnel in the following way within the extremely short time, i.e. at least some of energy consumption device is in short time with the Power operation improved.Particularly it can be stated that make heating arrangements run with peak power in short time.Temperature in shrinking tunnel inner chamber uses Sensor monitoring at this.Value that if shrinking tunnel internal temperature has exceeded restriction at this, that determine between the 85-95% of shrinking tunnel internal temperature Ti-PM in production model PM, then the power of heating arrangements is switched to produce normally power.By the operational mode according to method step f), on the one hand realize the quick heating of inner chamber, on the other hand avoid the overheated of shrinking tunnel inner chamber by regulation downwards timely.
Preferably, only when required shrinking tunnel internal temperature occurs, just open input and output area.In addition it can be stated that only when multi-pack to be processed is positioned at the entrance region of shrinking tunnel, just open input area.Additionally, only when the first multi-pack has been positioned in shrinking tunnel, output area just can be opened.Additionally, conveying mechanism can run with the transfer rate improved prior to or just when the first multi-pack is handed to conveying mechanism in short time.This prevents, and the quality of shrink wrapping suffers the accumulation of heat in shrinking tunnel.By 1 to 3/ time period on improve transfer rate in short time, identical heat is applied in the first multi-pack of passing through, as in other follow-up multi-pack, other multi-pack described are passed through shrinking tunnel with the conveying of normal transfer rate under normal working condition.Particularly when the heating of shrinking tunnel is without Sensor monitoring, this is required.
Embodiment according to method a kind of particularly preferred and shown in figure 2, it is used for making shrinking tunnel be transformed into standby mode SB from production model PM and be then transitioned in stop mode S, first closes shrinking tunnel input area and shrinking tunnel output area.The step of a continuation then reduces at aa) to dd) under the power of described energy consumption device.This occurs the most simultaneously.The effect of the closing of shrinking tunnel particularly, in high temperature is substantially stored in shrinking tunnel and need less energy to the backup temperature set-point Ti-SB being maintained in shrinking tunnel inside.As described in connection with fig. 1, shrinking tunnel can be completely cut through by control unit and this shrinking tunnel is placed in stop mode S.
Fig. 3 illustrates for making shrinking tunnel in production model PM and shutdown mode, the schematic overview of a kind of embodiment of method particularly changed between standby mode SB or stop mode S through middle operation mode BM.
In production model PM, shrinking tunnel input area and shrinking tunnel output area are least partially open, in order to make article or article collect body and pass through.When cutting off, first shrinking tunnel is placed in operational mode BM by the power of the customer by cutting off or within reduction shrinking tunnel.At this, the closedown of shrinking tunnel input area and/or the closedown of shrinking tunnel output area in the embodiment shown with shrinking tunnel within one of them customer power shutoff or reduce simultaneously carry out, the most substantially keep here inside shrinking tunnel exist heat.Then by cutting off or the power of other customers can be reduced according to combining the method step aa that Fig. 1 and 2 describes) and/or bb) and/or cc) and/or dd) and/or ee) and/or one of ff) shrinking tunnel is placed in shutdown mode, be particularly placed in standby mode SB or stop mode S.
If in order to shrinking tunnel should be transformed into production model PM by new production again from shutdown mode SB or S, then this realizes again by the intermediate steps of operational mode BM.According to the given actual temperature in shrinking tunnel inner chamber in shutdown mode SB or S, less energy must be applied if desired, to reach operational mode BM and then to reach production model PM.The shrinking tunnel input area of shrinking tunnel and shrinking tunnel output area are closed in shutdown mode SB or S.First passing through to connect or raise makes the power of the customer within shrinking tunnel improve.Opening of shrinking tunnel input area is carried out the earliest with opening of shrinking tunnel output area together with the connecting or raise of the power of the customer within contracting tunnel.In the embodiment shown, only after reaching operational mode BM, just open shrinking tunnel input area and open shrinking tunnel output area.When such as there is predetermined temperature in shrinking tunnel inner chamber, reach operational mode.In an illustrated embodiment, shrinking tunnel input area open with shrinking tunnel output area open particularly with the method step a) combined described by Fig. 1 and 2 and/or one of b) and/or c) and/or d) and/or e) and/or f) together with carry out.
With reference to preferred embodiment invention has been described.But for technical staff it is contemplated that the present invention can be retrofited or change, and at this without departing from the protection domain of appended claims.
