Description
Technical field
The present invention relates to a kind of according to described in claim 1 and 12 for moving the method for shrinking tunnel.Particularly, the present invention relates to a kind of a kind of method and method that makes shrinking tunnel be transformed into shutdown mode from production model that makes shrinking tunnel be transformed into production model.
Background technology
Known in filling and packaging facilities, wrap up object, particularly bottle, tank, beverage can or analogue and then its transmission passed through to shrinking tunnel by film.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, is also familiar with by technical personnel as LDPE, LLEPE-plastic film.With the object of such film parcel thereby be then transferred by shrinking tunnel, and be loaded hot air there after it wrap up in wrapping machine, thus film contraction and clinging on object.The cooled region with fan being directly connected on shrinking tunnel is responsible for cooling multi-pack rapidly, and these multi-pack obtain its intensity that can transmit thus.
Such shrinking tunnel now substantially by around continuous conveying mechanism form, this continuous conveying mechanism adds and is stamped enclosing (tunnel) in segmentation, this enclosing forms tunnel.In addition, shrinking tunnel is mostly by multiple heater elements and also have fan or blowing engine to form, to produce required hot air and then hot air be distributed in tunnel inner chamber.In order to realize disperseing especially uniformly of hot air, hot air is partly directed to so-called well bore wall neutralization and is partly directed in the chamber below the conveying mechanism that is located immediately at shrinking tunnel after it produces by suitable hot air guide portion.Therefore, multi-pack is preferably loaded hot air on one's own initiative from least three sides.The essential structure of shrinking tunnel is only explained herein roughly.Know the structure of such shrinking tunnel from the technical personnel of packaging industry, thereby needn't carry out further details description herein.
As set forth in beginning, such shrinking tunnel needs hot gaseous medium (being hot air mostly) that film is shunk.This hot air is produced by the heating arrangements that is shrinking tunnel component part.The hot air that the hot air producing is produced by heating arrangements in other words preferably utilizes electric energy to produce at this.During this period, people also transfer to produce required hot air by for example so-called gas burner.Unfortunately, required gas can not utilize without any problems in a lot of places, therefore just uses back again electrically heated shrinking tunnel.
Electrically heated shrinking tunnel like this has large demand for electric energy, has produced thus significant cost for operator.Particularly, being created in shrinking tunnel of hot air is maximum energy consumption device.Now people determine, the power consumption in shrinking tunnel can reduce in the following way, shrinking tunnel without for the production of some running state or operational mode in this shrinking tunnel is placed in to so-called standby mode.This reduce shrinking tunnel one or more consuming devices power and with respect to production run, low-energy-consumption falls therefore.
Such shrinking tunnel or such for making the method for shrinking tunnel operation for example known by DE 102,010 011 640 A1.Described a kind of shrinking tunnel here, this shrinking tunnel also has other so-called standby mode except conventional production model, wherein by this standby mode, shrinking tunnel is moved with the power reducing with respect to production model.Conversion between conventional production model and other standby mode is subject to time and/or signal control at this.In the time being transformed into standby mode, take some measures at this, these measures have reduced the energy requirement of shrinking tunnel.A measure for example, can be by being adjusted to respect on the backup temperature reducing to fixed temperature to fixed temperature of existing, and result is that required heating power is less.Another measure is for example the transfer rate that reduces the forwarder of shrinking tunnel side, minimizes to make to discharge (heat discharge in other words) from the energy in tunnel.Know again, cutting off forwarder cooling of shrinking tunnel side and also having the cooling multi-pack shifting out from shrinking tunnel is also the measure for reducing energy requirement.If each Close Tunnel is equipped with the blowing engine of at least two electricity operations, the energy requirement that cut-out of the blowing engine of the heating arrangements of each Close Tunnel can reduce.
In addition known, so-called standby mode has brought another measure, and wherein two openings in input area and the output area of shrinking tunnel seal at least in part.Shrinking tunnel input area and shrinking tunnel output area are so opened to degree in conventional production model according to logic, make multi-pack can pass in and out without hindrance shrinking tunnel.Shrinking tunnel input area and shrinking tunnel output area at this between corresponding operational mode when (that is between production model and standby mode) conversion or open or close.Conversion between these two operational modes is subject to equally time and/or signal control at this and is triggered.Thisly for example learnt by DE 10 2,010 020 957 A1 for the control setup and this shrinking tunnel itself that move shrinking tunnel.
Therefore above-mentioned prior art discloses a kind of shrinking tunnel or a kind of for controlling the method for shrinking tunnel, and it is subject to time and/or signal control and changes between two operational modes, in these two operational modes, produces respectively different energy requirements.In addition, the document discloses a kind of shrinking tunnel or a kind of for controlling the method for shrinking tunnel, opens or be enclosed in the shrinking tunnel opening in the input and output region of shrinking tunnel when this shrinking tunnel is changed extraly between two operational modes.
Summary of the invention
Object of the present invention is now; optimize like this prior art that proposes, further optimize and for example, for example, energy requirement when particularly (in standby mode) switches in other words between production model and shutdown mode (standby mode) in shutdown mode in minimize retraction tunnel.
Described object by a kind of according to described in claim 1 and/or 12, for making shrinking tunnel be transformed into the method for production model and realizing for the method that makes shrinking tunnel be transformed into shutdown mode from production model.
Show, after the conversion that is subject to time and/or signal control between each operational mode known by prior art, for moving or causing following result for the sequence of steps of restriction of indivedual measures first mentioned of controlling shrinking tunnel,, directly after conversion, just can again further reduce energy requirement until reach the preset value of corresponding operational mode.
Therefore, the present invention points out a kind of the first method that is transformed into production model for making to have the shrinking tunnel of conveying mechanism, and the method at least comprises to be opened shrinking tunnel input area and/or open shrinking tunnel output area.The method particularly can relate to putting into operation first of shrinking tunnel or the conversion of shrinking tunnel from standby mode to production model.In addition can make shrinking tunnel be transformed in production model, in this shrinking tunnel because longer floor time has cut off all energy consumption devices and this shrinking tunnel therefore in so-called stop mode.Important difference between standby mode and stop mode is, shrinking tunnel remains on lower second on fixed temperature in standby mode as known by prior art.By switch all energy consumption devices in stop mode, the inside of shrinking tunnel can be cooling until ambient temperature according to the time length of floor time.If shrinking tunnel should be risen to production model again, do not know in advance actual tunnel temperature.
Described method comprises at least one following step: a) cavity temperature in shrinking tunnel is brought up to predetermined given value; B) connect conveying mechanism or the speed of conveying mechanism is brought up to predetermined given value; C) chain cooling power is brought up to predetermined given value with coolconveyer structure; D) multi-pack cooling power is brought up to predetermined given value.According to the present invention, shrinking tunnel input area open and/or opening the earliest with step of shrinking tunnel output area carried out together with one of a), b), c) and/or d).Preferably, each given value has referred to production value.
Should again slightly at length inquire into herein for according to the component part of the required shrinking tunnel of method of the present invention, these component parts in process after a while for being important according to method of the present invention.
For being formed by component part at least described below at this according to shrinking tunnel of the present invention according to method of the present invention.Such shrinking tunnel has the unit hot air blowers of fan, heating recording instrument, forms of sensor (for example with) of motor-driven conveying mechanism and one or more also combinations, these units produce for essential hot air and are therefore essential for the adjusting of cavity temperature in shrinking tunnel, correspondingly in order to reach predetermined given value for example with DEG C temperature representing.Particularly, in the inner chamber of shrinking tunnel, can be provided with sensor, these sensors are tried to achieve actual temperature and value are continued to send to control unit.By actual temperature with compare to fixed temperature, and hot air blowers and/or heating recording instrument are regulated so again, thus regulate in shrinking tunnel inner chamber to fixed temperature.In addition, for thering is so-called current source cooling mechanism according to method of the present invention according to shrinking tunnel of the present invention, this current source cooling mechanism is for example made up of the unit (as fan and sensor if desired) of one or more also combinations, these units are arranged on outside tunnel inner chamber, preferably around conveying mechanism below.Cooling unit is for coolconveyer structure, and this conveying mechanism is for example mesh grille band chain or so-called excellent roller chain.Conveying mechanism is heated in the time that delivery tunnel is moved continuously.At it, again by before shrinking tunnel, it must cool down in the time returning, because otherwise just exist the article of package media and/or subsequent delivery to melt at least partly and stick to the danger on conveying mechanism.In addition, for example, for thering is at least one or more also unit of combinations (axial fan or cross flow fan) according to method of the present invention according to shrinking tunnel of 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 thereby be necessary for essential cooling power.In addition, for specifying according to method of the present invention, in according to the region of two tunnel openings of shrinking tunnel of the present invention, be provided with door or other suitable closure elements, described door or closure elements are automatically closed when needed or open, and wherein under the closed condition of door or closure elements, reduce from the heat of shrinking tunnel and discharge.In order to make mode and method, particularly the sequence of steps operation to limit of all consuming devices of mentioning to limit, shrinking tunnel also comprises the control setup of oneself, can implement according to method of the present invention by this control setup.In this control setup, store for data essential according to method of the present invention.Preferably, be also equipped with at least one sensing mechanism (for example grating) and be equipped with at least one other sensing mechanism (for example grating) in the discharge side in tunnel at the approaching side in tunnel according to the required shrinking tunnel of method of the present invention.In addition, for according to method of the present invention importantly, oneself control unit of shrinking tunnel has to being set directly at wrapping machine before shrinking tunnel or the interface to the control unit of wrapping machine, and the communication mutually of these interfaces.For shrinking tunnel and the communication interface that is arranged on wrapping machine above for example can be carried out via so-called ethernet at this.
Because the essential each single measure according to operation of the present invention for shrinking tunnel requires different energy requirements in step 1 aspect in other words, and on the other hand according to the specific different time of parameter request, so advantageously, introduce these single measure or steps with the order limiting.
The order of the restriction by each single step, can be reduced in the energy requirement during specific measure again.Taking production model and standby mode as departure point, the each pattern in these two operational modes therefore first must carry out some also the given value based on limiting as the step of preset value.In order to reach these given values, therefore open specific measure or step along with each conversion from from an operational mode to another operational mode.Show, in the time that each step or measure are carried out with the order limiting, can again be reduced in the energy requirement between indivedual or multiple step effective dates by the order of this restriction.
Therefore first conclusive according to method of the present invention, when carry out single step or multiple step, and the time length of a step or multiple steps is for how long, to carry out this step completely
Should illustrate according to method of the present invention and according to other embodiments of method of the present invention or further improvement project according to detailed description below.
At least comprise and open shrinking tunnel input area and/or open shrinking tunnel output area at this for the method (should make in the method shrinking tunnel be transformed into production model) of moving shrinking tunnel according to of the present invention.In the time that shrinking tunnel is initially located in standby mode also or when shrinking tunnel cut off completely in advance in stop mode time, as it is for example the situation in the time putting into operation first, adopt this method.In addition also at least comprise according to method of the present invention: step a) is brought up to predetermined given value by cavity temperature in shrinking tunnel; And/or step b) is connected conveying mechanism or the speed of conveying mechanism is brought up to predetermined given value; And/or step c) is brought up to predetermined given value by chain cooling power; And/or steps d) multi-pack cooling power is brought up to predetermined given value.Due to shrinking tunnel input area open and/or opening the earliest with above-mentioned steps of shrinking tunnel output area a) carried out together with one of d), so reduced the energy requirement according to method of the present invention.
According to another kind of method flexible program suggestion of the present invention, shrinking tunnel input area and/or the opening with step a) to one of d) carry out or carry out after one of a), b), c) and/or d) in step the latest simultaneously of shrinking tunnel output area.
Therefore for example particularly advantageously, use a kind of for moving the method for shrinking tunnel, wherein, shrinking tunnel input area open and/or opening when cavity temperature reaches above-mentioned predetermined given value in shrinking tunnel of shrinking tunnel output area carried out.Therefore during the heat process of shrinking tunnel inner chamber, it is by the consumed energy of multiple electric power, the separately or also unit of combinations (realization), original text is imperfect), prevent that shrinking tunnel input area and/or shrinking tunnel output area from opening in advance.For example, therefore can as far as possible effectively move for the essential unit of heat process (heating recording instrument, heater blower, blowing engine), because in shrinking tunnel input area and/or the state of shrinking tunnel output area in closing.If two shrinking tunnel input and output regions sealing during heat process, the time length of heat process also shortens thus, has particularly shortened step and a) cavity temperature in shrinking tunnel has been brought up to the time length of predetermined given value.When reached the predetermined given value of cavity temperature in shrinking tunnel in a) in step, by opening the earliest shrinking tunnel input area and/or shrinking tunnel output area, can reduce the duration of heat and make in addition thermal loss minimize, reduce thus for the energy requirement of the step accumulation obtaining thus a) and reduced.In addition by opening the earliest shrinking tunnel input area and shrinking tunnel output area, this only has in the time reaching given value a) of step and just carries out, owing to having shortened the duration of heat, so shortened the preparation time length for the essential given state of production of shrinking tunnel.
In the special embodiment of another kind, the continuation that step " opening of shrinking tunnel input area and/or opening of shrinking tunnel output area " a) is brought up to cavity temperature in shrinking tunnel predetermined given value due to step is carried out.Therefore before the predetermined given value for cavity temperature in reaching for shrinking tunnel, prevent soon the formation accumulation of heat at shrinking tunnel inner chamber, shrinking tunnel input area open and/or opening in the time reaching predetermined temperature (it is lower than the given value for the production of pattern) of shrinking tunnel output area just can be carried out.Avoided thus the possible accumulation of heat within shrinking tunnel to form, this accumulation of heat forms and may cause first multi-pack of carrying by shrinking tunnel overheated.In other words, due to reaching having opened shrinking tunnel input area and/or opened shrinking tunnel output area to when fixed temperature of restriction, should be for example suitable with 90 – 95% of the predetermined given value of shrinking tunnel internal temperature to fixed temperature, can avoid accumulation of heat within shrinking tunnel to form, thus step a) by shrinking tunnel in cavity temperature bring up to predetermined given value be transferred the first multi-pack of passing through after completing can be overheated or damage.This improves the quality of the first multi-pack of processing in shrinking tunnel, otherwise these multi-pack may must be dropped.
According to the special embodiment of the another kind of method of the present invention regulation, predetermined to fixed temperature by shrinking tunnel being continued be heated to, perform step b) that is connects conveying mechanism or the speed of conveying mechanism brought up to predetermined to fixed temperature.For example can specify, when the temperature in shrinking tunnel inner chamber roughly reach given value 90% time, just connect conveying mechanism.Conveying mechanism needs specific to fixed temperature for production model is same.If conveying mechanism is excessively cold, this negatively affects the quality of the contractive effect in multi-pack bottom section.If cut off conveying mechanism in standby mode, in the time that shrinking tunnel inner chamber heats substantially only the transit area within shrinking tunnel be heated.And the return area of conveying mechanism is according to arrangement structure, maintenance is cold.Connect moment of conveying mechanism improve in other words conveying mechanism speed time be engraved in this and select like this, make sufficiently to be heated at the All Ranges of the required time durations conveying mechanism of the final given value for shrinking tunnel being heated to required shrinking tunnel internal temperature in the time passing through shrinking tunnel, thereby this conveying mechanism is heated to essential production temperature all sidedly.
Simultaneously may be essential, connect chain cooling body or improve chain cooling power, to the temperature of conveying mechanism, particularly there is desirable temperature shrinking in tunnel tunnel input area.
Therefore specify according to the special embodiment of the another kind of method of the present invention, according to the chain temperature of trying to achieve, chain cooling power is brought up to predetermined given value.In shrinking tunnel in normal production model coolconveyer structure (for example mesh grille band chain link, excellent roller chain) constantly, be heated to prevent that this conveying mechanism from crossing doughtily.Crossing the conveying mechanism being heated by force will cause package media to melt and may also will cause the partial melting of article.This causes conveying mechanism to be polluted by plastic residue and hinders the transmission continuing.In addition, this may affect the quality of the multi-pack of contraction significantly.Now according to method regulation of the present invention, except the shrinking tunnel input area that carries out together with one of a), b), c) or d) with step the earliest open and/or the opening of shrinking tunnel output area, during step c) that is during raising cooling power is with coolconveyer structure, improve chain cooling power according to the conveying mechanism temperature of trying to achieve.Improve chain cooling power according to the conveying mechanism temperature of trying to achieve, this cooling power only ought also really just improve if desired.Therefore low-energy-consumption can further fall targetedly and effectively.The temperature of conveying mechanism is particularly in delivery tunnel output area or be connected on and try to achieve by the sensor-type measurement of temperature after shrinking tunnel output area and by itself and predetermined given value comparison.The temperature value that this given value and conveying mechanism should have in shrinking tunnel input area is suitable.In the time that conveying mechanism returns between shrinking tunnel output area and shrinking tunnel input area, suitably coolconveyer structure.Cooling effect can be by being arranged on that the second temperature sensor in return area is checked and matched chain cooling power again if desired.
In addition show, significantly can be, shrinking tunnel door or closure elements be not only opened according to shrinking tunnel internal temperature, and according to being produced by the wrapping machine that is arranged on upstream and carrying and open by the multi-pack of shrinking tunnel via conveying mechanism.Therefore can avoid equally the degradation of energy causing owing to opening too early shrinking tunnel door or closure elements here.Therefore for example in the time that wrapping machine starts, can utilize the following time, wrapping machine utilizes this time that the first multi-pack film that and then transfers to shrinking tunnel is wrapped up.This time is not small.Due to wrapping machine with the restarting of each step that first will carry out (as each single article being arranged to a multi-pack organizator, multi-pack organizator being continued transported in film packaging module, wraps up multi-pack organizator, conveying mechanism is exported and transferred to the film multi-pack of wrapping up with contractile film), spent the regular hour, until for its conventional production task (shrinking multi-pack) need to this shrinking tunnel.Can expect, shrinking tunnel input area only has in the time that wrapping machine has started to manufacture film multi-pack and parcel thereof just to be opened.Particularly preferably, shrinking tunnel input area is along with opening with the making just of the first multi-pack of shrink film parcel.Shrinking tunnel tunnel output area can open under identical condition, also or only had in the time that realization is passed the regular hour according to the speed of conveying mechanism and just open.According to making and transmission on conveying mechanism of wrapped film multi-pack, and according to the known delivery speed of conveying mechanism, can very accurately try to achieve, how long the transmission of the first multi-pack need to arrive at shrinking tunnel output area.Therefore shrinking tunnel output area was opened in time before multi-pack reaches it.
Another kind also allows special mode and the method more effectively controlling shrinking tunnel door and do not need complicated program work to be, shrinking tunnel input area and shrinking tunnel output area have respectively the sensing mechanism of oneself.The design plan of sensing mechanism was at least provided with the first grating at this before shrinking tunnel input area.According to the time gap that takies and subscribe, the opening the moment of two shrinking tunnel doors of this grating device control, wherein first shrinking tunnel input area is opened and shrinking tunnel output area was just opened after interval elapses in the predetermined time of following.Alternatively, shrinking tunnel output area also can opening and open simultaneously with shrinking tunnel input area.This mode of opening of two shrinking tunnel doors or closure elements looks like particularly preferred, and be the simplest and the most direct mode and method simultaneously, to as far as possible accurately open shrinking tunnel door or closure elements, when this is while being essential, when that is to say in multi-pack enters shrinking tunnel or being positioned at the defeated foremost as region of shrinking tunnel or when multi-pack is in the time that shrinking tunnel is positioned at the foremost of shrinking tunnel output area.
Be noted that at edge shrinking tunnel door also can be used for as far as possible directly and rapidly closing shrinking tunnel input area and shrinking tunnel output area via this mode and the method for grating device control.Can specify for this reason, before shrinking tunnel input area and directly, after shrinking tunnel output area, be respectively arranged with grating.
This external shrinking tunnel starts or when stand-by state rises to the activation measure production model completely, conveying mechanism can be before the first multi-pack transfers to conveying mechanism or in the transfer rate operation to improve in short time.This additional method step only contributes to optimization energy demand or energy consumption indirectly.Only along with or only reaching the essential given running temperature in shrinking tunnel inner chamber before just activate and open soon portal, because the door of closing before forms so-called accumulation of heat in shrinking tunnel.If now the first multi-pack is directly sent after door is opened to shrinking tunnel or is passed shrinking tunnel, the accumulation of heat that these first multi-pack improve before suffering.This may cause, and the first multi-pack of sending in shrinking tunnel may be applied in too much heat.May be essential for this reason, after shrinking tunnel door is opened subsequently, the transfer rate of conveying mechanism at short notice higher than routine for the essential transfer rate of normal production run.Therefore pro rata, owing to having improved at short notice transfer rate, be applied in first multi-pack of advancing with heat identical in follow-up other multi-pack, these follow-up other multi-pack are transferred and pass through shrinking tunnel with normal transfer rate under normal working condition.In order to understand fully which is that the transfer rate that improves is transmitted through the first multi-pack of shrinking tunnel and which is the follow-up multi-pack that moves through shrinking tunnel under normal working condition here, be noted that herein that the first multi-pack comprises at least five multi-pack but the amount of maximum 25 multi-pack.If people also will make other multi-pack carry by shrinking tunnel with the transfer rate improving, because accumulation of heat lacks the contraction structure that can not ensure again optimization.The short-term of transfer rate improves can be defined as approximately 1 to 3 minutes in time.
The same as has been described, shrinking tunnel can be in stop mode, and in this stop mode, all energy consumption devices cut off completely.Also or shrinking tunnel in standby mode, in this standby mode, the power of energy consumption device reduces at least in part.Part energy consuming device (for example a part of heating arrangements) also can cut off completely at this.Substantially can make shrinking tunnel return to relatively rapidly production model from standby mode.And all energy consumption devices cut off in stop mode, thereby shrinking tunnel even can cool to room temperature according to the time length of floor time.Particularly, by implementing all method steps a) to e) afterwards control unit being placed in to stop mode, introduce the stop mode of shrinking tunnel, cut off thus all energy consumption devices.For shrinking tunnel is placed in to production model again, therefore can specify in f) in other method step, first by control unit and shrinking tunnel wakes up from stop mode and it is transformed in so-called operational mode, in this operational mode, all heating arrangements of for example shrinking tunnel are with maximum Power operation.If then reach roughly with given internal temperature in standby mode or with approximately 85 to 90% of given internal temperature in standby mode suitable shrinking tunnel internal temperature, the power and the unlatching that 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 ofly for making shrinking tunnel be transformed into the method for production model, wherein said method at least comprises to be opened shrinking tunnel input area and/or opens shrinking tunnel output area.Regulation here, the shrinking tunnel input area of shrinking tunnel and shrinking tunnel output area are first in closed state.First shrinking tunnel is transformed in operational mode.This by connect or the shrinking tunnel that raises within the power of at least one consuming device carry out.Opening of shrinking tunnel input area and/or opening the earliest with the power-on of described at least one consuming device within shrinking tunnel or raise and carrying out of shrinking tunnel output area.Particularly regulation, shrinking tunnel input area open and/or shrinking tunnel output area open only have when reach in shrinking tunnel inner chamber minimum temperature time just carry out.This for example checks and controls via the temperature sensor being coupled with control unit.Then the power of other consuming devices is brought up to production power, regulate thus the production model of shrinking tunnel.
The invention still further relates to a kind of for making shrinking tunnel be transformed into the method for shutdown mode from production model.Shutdown mode can be understood as following standby mode, the Power operation of shrinking tunnel to reduce in this standby mode.But standby mode also can be understood as following stop mode, in this stop mode, all energy consumption devices of shrinking tunnel cut off completely.This method at least comprises closes shrinking tunnel input area and/or closes shrinking tunnel output area.In addition, this method comprises at least one following step: aa) shrinking tunnel internal temperature is reduced to predetermined given value; Bb) speed of conveying mechanism is reduced to predetermined given value; Cc) chain cooling power is reduced to predetermined given value; Dd) multi-pack cooling power is reduced to predetermined given value.According to the present invention regulation, closing of shrinking tunnel input area and/or closing the latest and step aa of shrinking tunnel output area), bb), cc) or one of dd) together with carry out.
In addition can specify closing of shrinking tunnel input area and/or closing as far back as step aa of shrinking tunnel output area), bb), cc) or one of dd) before carry out.Particularly preferably, closing of shrinking tunnel input area and/or closing as first step at step aa of shrinking tunnel output area), bb), cc) or one of dd) before carry out.Particularly, step aa), bb), cc) or dd) can by arbitrarily order or the time carry out in the same manner.
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, in the time that being heated, shrinking tunnel always ensures, not continuously to conveying mechanism supply heat.Particularly in return area, there is no heat supply, thereby conveying mechanism always can cool down respectively partly.If the temperature of the transfer rate of conveying mechanism in shrinking tunnel inner chamber reduced before reducing or conveying mechanism stops completely, the strongly overheated of conveying mechanism may occur partly in shrinking tunnel inner chamber, and this also may cause damaging other component parts within conveying mechanism or shrinking tunnel.The same as has been described, conveying mechanism conventionally also must be cooling in normal production run for this reason, so that the damage to the multi-pack of processing of avoiding the overheated of conveying mechanism and causing thus.
According to one embodiment of the present invention, the reduction of chain cooling power is carried out with together with the reduction of conveying mechanism speed the latest.Obtain 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 side by side carried out.
In addition the present invention also comprises an additional step ee), utilize this step to try to achieve the position of the multi-pack of carrying on conveying mechanism and close shrinking tunnel input area and/or shrinking tunnel output area according to tried to achieve position.
If should carry out for making the method for shrinking tunnel from production model conversion shutdown mode, no longer pending multi-pack is supplied to shrinking tunnel.But, the multi-pack that do not have during shutdown mode is stayed in shrinking tunnel.Therefore, a shrinking tunnel input area in the end multi-pack seals after entering in shrinking tunnel, and shrinking tunnel output area can only have just sealing in the time that last multi-pack has been left shrinking tunnel.But because may form accumulation of heat in this case, thus after all multi-pack have all been left shrinking tunnel preferably two regions seal simultaneously.
In the time of the floor time that insight is grown in advance, also can specify in other embodiments method step aa), bb), cc) and/or each given value dd) equal zero.Particularly in so-called stop mode, specify, cut off all energy consumption devices of shrinking tunnel.Also can not monitor in this case shrinking tunnel internal temperature, thereby this shrinking tunnel can be cooled to roughly suitable with the ambient temperature existing temperature under limiting case.
Particularly, implementing the aa in steps of institute the latest) to ee) can specify afterwards another step ff), the control unit of shrinking tunnel is placed in stop mode by this additional step.Aa in steps) to ee) and enforcement mean especially longer floor time, and therefore cut off all energy consumption devices completely with the signal that acts on control unit.

For the present invention identical or the element of same function used identical Reference numeral.In addition for the sake of clarity, Reference numeral essential for the explanation of respective drawings is only shown in each accompanying drawing.Shown embodiment is only the example of how design consideration method of the present invention and does not form enclosed restriction.
Fig. 1 illustrates for making shrinking tunnel be transformed into the schematic synoptic chart of the method for different operational modes.In production model PM, shrinking tunnel has the internal temperature Ti-PM that moves required restriction for normal contraction substantially.This internal temperature is lower than the fusion temperature of packing and article.For example, internal temperature Ti-PM is approximately 200 DEG C in production model PM.Conveying utilizes the article of package media parcel or article to collect speed of production V (the F)-PM motion of the conveying mechanism of body by shrinking tunnel to be scheduled to.Conveying mechanism refers to the continuous conveying mechanism of continuous motion especially.When heating up and return between shrinking tunnel input area and shrinking tunnel output area in the time passing through shrinking tunnel, this conveying mechanism again cools down at least in part via the first blowing engine or other the first cooling system conditioner feeders.In production model, the first cooling system conditioner feeder is with cooling power P (F)-PM work.In addition, multi-pack cools down by the second blowing engine or other the second cooling system conditioner feeders after leaving shrinking tunnel, and then they are supplied to other processing unit (plant)s.In production model PM, the second cooling system conditioner feeder is with cooling power P (G)-PM work.
In order to be reduced in by the energy requirement of producing or keeping in repair during the floor time causing, shrinking tunnel can be placed in the first standby mode SB.Particularly, following measures is performed individually or with combination in any.
Aa) shrinking tunnel internal temperature is reduced to predetermined given value Ti-SB, this given value for example under the shrinking tunnel internal temperature Ti-PM in production model for example between 50 DEG C to 80 DEG C.
Bb) in addition, by the Speed Reduction of conveying mechanism, to predetermined given value V (F)-SB, this given value is lower than at production run speed V (the F)-PM of conveying mechanism in production model PM in other words.
Cc) chain cooling power is reduced to predetermined given value P (F)-SB, this given value is lower than at production run chain cooling power P (the F)-PM in production model PM in other words.
Dd) multi-pack cooling power is reduced to predetermined given value P (G)-SB, this given value is lower than at production run multi-pack cooling power P (the G)-PM in production model PM in other words.
In addition, shrinking tunnel input area and shrinking tunnel output area the latest with step aa), bb), cc) or one of dd) together with seal by door or other suitable closure elements.
Preferably, at method step ee) in try to achieve the position of the multi-pack of carrying on conveying mechanism.Closing according to the position of tried to achieve multi-pack of shrinking tunnel input area and/or shrinking tunnel output area carried out.Particularly, only have when in the time there is no multi-pack towards entering of shrinking tunnel in region, just seal shrinking tunnel input area.In addition, only have in the time no longer including multi-pack in shrinking tunnel inside, just seal shrinking tunnel output area.
In the time that shrinking tunnel reaches standby mode SB, particularly just can be at method step ff in the time of longer floor time) in control unit is placed in to stop mode.Start thus to cut off completely all energy consumption devices of shrinking tunnel and shrinking tunnel is placed in to stop mode S.In stop mode S, method step aa) to dd) given value suitable with null value respectively.Particularly cut off heating arrangements, thereby the inner chamber of shrinking tunnel is cooling and be substantially matched with ambient temperature RT according to the time length of floor time uncontrollably.In addition, cut off conveying mechanism itself and chain cooling body and multi-pack cooling body completely.
For shrinking tunnel is transformed into production model PM again from standby mode SB, following measure is performed individually or with combination in any:
A) shrinking tunnel internal temperature is heated to the predetermined given value for the production of the shrinking tunnel internal temperature Ti-PM of pattern PM.
B) speed of conveying mechanism is brought up to speed V (the F)-PM of the conveying mechanism in production run.
C) chain cooling power is brought up to chain cooling power P (the F)-PM in production run.
D) multi-pack cooling power is brought up to multi-pack cooling power P (the G)-PM in production run.
In addition will in shrinking tunnel input area, open together with one of a), b), c) or d) with step the latest with door in shrinking tunnel output area or closure elements.
For shrinking tunnel is transformed into production model PM again from stop mode S, substantially there are two kinds of possibilities.In the time of the first possibility, control unit is converted to enable mode from stop mode.Connect at least in part each energy consumption device of shrinking tunnel at this, thereby shrinking tunnel is placed in standby mode, this standby mode has speed V (F)-SB, chain cooling power P (the F)-SB of reduction and/or multi-pack cooling power P (the G)-SB of reduction of the conveying mechanism of shrinking tunnel internal temperature Ti-SB, the reduction of restriction.Then make tunnel power finally be matched with production model PM and open input and/or the output area of shrinking tunnel.
Alternatively, control unit can be converted to operational mode from stop mode.This is for setting up in the following way the production model PM of shrinking tunnel within the time extremely short, that is, at least a portion energy consumption device is the Power operation to improve in short time.Particularly can specify, heating arrangements is moved with maximum power in short time.Temperature in shrinking tunnel inner chamber is used Sensor monitoring at this.If shrinking tunnel internal temperature this exceeded restriction, in production model PM between the 85-95% of shrinking tunnel internal temperature Ti-PM definite value, the power of heating arrangements is switched to normal production power.By according to method step operational mode f), realize on the one hand the Fast Heating of inner chamber, on the other hand by regulating and avoided the overheated of shrinking tunnel inner chamber timely downwards.
Preferably, only have in the time there is essential shrinking tunnel internal temperature, just open input and output region.In addition can specify, only have when the multi-pack that will process be positioned at shrinking tunnel enter region time, just open input area.In addition, only have in the time that the first multi-pack has been positioned at shrinking tunnel, just can open output area.In addition, conveying mechanism can be before the first multi-pack be handed to conveying mechanism or in the transfer rate operation to improve in short time.This prevents, the quality of shrink wrapping suffers the accumulation of heat in shrinking tunnel.By improving in short time transfer rate on the time period between 1 to 3 point, identical heat is applied in the first current multi-pack, as in other follow-up multi-pack, described other multi-pack are carried and are passed through shrinking tunnel with normal transfer rate under normal working condition.Particularly, when the heating of shrinking tunnel is during without Sensor monitoring, this is essential.
