Transportation unit
Preferably several described soft bags are incorporated in the transportation unit.Preferred transportation unit is a rectangle.In this manner, transportation unit is suitable for storing and transportation with other similar transportation unit stackings.Complete fabricate block or tray stacks have been obtained by the several this transportation units of stacking.Preferably, can be packaged in several soft bags in the secondary package and form transportation unit.From hereinafter as can be known level package spare be the soft bag that washer solvent itself is housed.
According to secondary package of the present invention is soft and not withstand voltage.Preferred secondary package can be by the rolling thin film fabrication.Preferred rolling film is by polyethylene or paper substrate thin film fabrication.Preferred paper substrate film is that a kind of plastic film layers is pressed onto the film of making on the paper.Preferably polyethylene film thickness scope is about 20 μ m～200 μ m, and more preferably its scope is about 50 μ m～100 μ m.Preferred paper substrate film weight scope is about 50g/m 2～200g/m 2For example: the paper substrate film is that polyethylene layer and the weight of 50 μ m is 80g/m by thickness 2Ply of paper make.
Preferably, adopt a kind of vertical wrapping machine commonly used, so-called vertical moulding filling sealing (VFFS) machine, the bag that carries out filling washer solvent is packaged into the packaging process of secondary package.The sectional perspective of this vertical wrapping machine is illustrated in Fig. 1.This vertical wrapping machine comprises moulding shoulder (10) at least inter alia.The method of making secondary package with VFFS is a kind of continuous batch production process.Send flat pattern film (1) to the VFFS machine.It also is the moulding shoulder (10) of filling head (11) that this film is transported to.Film dragged around the moulding shoulder (10) that extends into VERTICAL TUBE.
By dragging plastic sheeting around the moulding shoulder, plastic sheeting be shaped to tubulose with vertically lapped limit (2)." vertically " refers to that on meaning these edge fits are parallel to the filling direction of VFFS machine.For keeping plastic sheeting in a tubular form, the vertically lapped limit (2) of film by involution wholly or in part together.Preferably, vertical edge only the part involution promptly, interrupt involution at least one zone along vertical edge (2) together.Involution interrupts having formed leading to the free path of secondary package in-to-in.The size of this interruption involution makes the user can insert discontinuity area to a finger at least, but can not must be enough to make spilling of level package spare (15) of having feeded again greatly.Preferably, the size of discontinuity area can be inserted a hand.By allowing the user to insert at least one finger or a hand in discontinuity area, tear the part involution along vertical edge (2), and be convenient to open secondary package.Preferably, form an above discontinuity area along vertical edge (2) part involution.For example: if vertical edge (2) is long for 80cm, involution 2cm is long so, interrupts 11cm, and then involution 2cm.Be repeated to 80cm along vertical edge like this.The vertical edge (2) long for 50cm also can carry out according to this.
The further involution tubular-film in the filling head opposite end has the underseal (3) of the transverse sealing that is arranged in outside clamping element (14) with formation.The bag of making in this way is exactly that it has the open end of the filling head that leads to the moulding shoulder according to secondary package of the present invention (20).At this moment, several level package spares of having feeded are through filling head and the open end secondary package of just can packing into.
The level package spare of feeding (15) falls into secondary package (20) through the secondary package open end again through filling head (11).The level package spare of feeding is from underseal (3) sign indicating number of secondary package.Preferably, the mode that the level package spare of charging falls into secondary package is that the level package spare of charging does not rotate during falling into this secondary package therein.When the shape of the level package spare of having feeded allows to have the minimum package space in prescribed direction, rather than when the different directions that can force secondary package need increase packaging space had the minimum package space, this was a particular importance.In fact, for example wide rather than along it for the level package spare that rectangle has been feeded along the length of level package spare or when highly arranging by the level package spare that will feed, can reduce the length of secondary package.Preferably the size according to the size cutting secondary package of the level package spare of having feeded realizes this point.For example: secondary package is a rectangle, and its size is as follows: be about 38cm, wide about 14.5cm, high about 14.5cm.So just four soft bags that are of a size of that about 9.2cm is long, 14.5cm is wide, 14.0cm is high can be wrapped among the aforesaid secondary package.
Preferably, the level package spare of having feeded that at first should enter a secondary package comes together through arrangement.Any fixing means such as strapping also can not be used in the ordering of the level package spare of feeding.So the level package spare of having feeded that comes together is to put in order group as one of ordering to fall into secondary package.Have now found that the ordering of this level package spare of having feeded has also guaranteed, the bag of having feeded does not turn upside down during falling into secondary package, and what other party also not in office is upwards rotated.
Preferably, during the filling secondary package, the outside clamping element (14) of VFFS is clamped secondary package around underseal.This outside clamping element is commonly used to clamping films when involution and/or cutting film.In fact, film is fixed between two half blocks of outside clamping element usually, and then involution and/or cutting.In this case, when the level package spare that filling has been feeded, will be fixed near the film the underseal between two half blocks of outside clamping element earlier, so that support the landing of level package spare in secondary package of having feeded.This is stretched with regard to the film of having been avoided secondary package during level package spare landing of having feeded and stacking and breaks.Have now found that, can be by this way fall to total weight in the secondary package, that outside clamping element is not had any danger and be up to 25 kilograms through filling head.Yet VFFS can provide other supporting method, lands so that support the level package spare of having feeded, and can bear higher load.
Preferably, in case secondary package with several level package spare fillings of having feeded, and underseal (3) sufficiently cools off, and just opens outside clamping element (14), the secondary package that the level package spare of having feeded is housed advances to bearing set (16).Preferred bearing set is held the secondary package that level package spare is housed during secondary package is advanced, until the level package spare of the charging of all secondary package of packing into all under transverse sealing.Preferred this bearing set is positioned under the outside clamping element (14), and it is made of movable flat board, and preferably its sense of motion is parallel to the direction that level package spare is filled secondary package.Hold the secondary package of having filled by bearing set, reduce the tension force on the secondary package film, reduced the possibility of this film breaks like this.Bearing set also helps to regulate the height of the closedtop of the secondary package of opinion according to the level package spare height of having feeded in the secondary package.Therefore, bearing set has guaranteed that closedtop seals tightly round the top of secondary package of the bag of having feeded.Preferred bearing set can also promote the secondary package of filling with level package spare towards transverse sealing, so that proofread and correct the position of secondary package closedtop.
Therefore, preferably pack the level package spare of having feeded in the secondary package, so that rotation or the turn upside down space of level package spare in secondary package is all less in mode substantially closely.This means that the secondary package of filling with the level package spare of having feeded is preferably formed bag bundle part closely.However, secondary package itself is not applied to any tension force on its package of having feeded that is equipped with.So secondary package can prevent that the level package spare of having feeded is out of shape by secondary package, particularly when level package spare is the soft bag of having feeded.In fact, for example: when bag mode with the elastic film winding of having feeded tied together, the soft bag of having feeded of rectangle can be deformed into circle.Circular soft bag of having feeded is imperfect when one its bag of stacking is tied part on another, because its stacking stability is low than rectangular bag.
As another preferred scheme, before the closedtop of sealing with respect to the underseal of secondary package, preferred outside clamping element is closed substantially once more, and the film feed arrangement of the film in the VFFS machine reverses.In such a way, upwards drawn secondary package again, be pressed onto on the outside clamping element until the level package spare of having feeded to small part.In fact, outside clamping element is closed substantially, thereby the level package spare of having feeded can not pass outside clamping element.Preferred outside clamping element closure is more than 50%, and more preferably closed about 80%.This descends the length of the used film of secondary package.Therefore, the level package spare of having feeded in the preferred secondary package is packaged in tight substantially mode, so that level package spare rotates in secondary package or the space of turning upside down is less.This means that the secondary package of filling with the level package spare of having feeded is preferably formed bag bundle part closely.Have now found that, linked together if the film feed arrangement of VFFS machine this reverses as previously mentioned with bearing set, then further improved the effect of packing the level package spare of having feeded with secondary package.And, hold the secondary package that oneself fills by bearing set, the tension force on the film of secondary package is descended, this has reduced the possibility of breaking of this film.
For forming closedtop (4), outside clamping element should be closed fully.In case clamping element is closed fully, with respect to underseal, closedtop (4) has just formed, thereby makes the secondary package complete closed of the level package spare that filling feeded.In addition, also above closedtop, cut off this osed top secondary package.In case closedtop cools down, just disengage osed top finished product secondary package from outside clamping element.Above-mentioned packaging system preferably uses a kind of enough tight film to pack, so that produce the bag bundle part that the distortion of level package spare does not take place.In fact, the level package spare of feeding for example compares with elastic film in according to secondary package of the present invention, is not under the significant tension force.However, level package spare is enough tied tightly, thereby prevented that level package spare is significantly mobile in secondary package.
Preferably, underseal (3) and/or closedtop (4) are the interruption involution, rather than continuous involution.Usually, along the hard straight landing edge (2) of underseal and closedtop fully involution to underseal and closedtop.Yet this does not allow to be positioned at the underseal of secondary package and near the level package spare of having feeded of the end of closedtop is deviate from.In fact, only near the secondary package middle part, just big must being enough to of the opening on vertically lapped limit can be taken out the level package spare of having feeded in secondary package.If the level package spare of having feeded that is arranged in the middle of the secondary package takes out from secondary package earlier, the level package spare of having feeded in the end could take out from secondary package so.Therefore, only when the level package spare of having feeded of end can be taken near the middle part of secondary package, these level package spares of having feeded could be extracted out from secondary package.
On the contrary, have been found that, vertically lapped limit if (2), at least at overlap (2a) along the vertical edge of underseal and/or closedtop, any do not have involution to or only the part involution to the underseal and/or the closedtop of secondary package, so all level package spares of having feeded all can more easily be extracted out from secondary package, and usually need not by above-mentioned whole steps.In fact, do not have vertically lapped limit involution or the part involution part provide between the vertical edge, near the also enough big opening underseal and/or closedtop.Therefore, can easily directly from secondary package, extract out at the level package spare of having feeded of the end of secondary package, and usually need not the secondary package of soaring earlier.
For realize vertically lapped limit (2) not involution to or only the part involution is to underseal (3) and/or closedtop (4), transverse sealing in the involution district on the corresponding whole or vertically lapped limit of part, exists interruption.This involution is interval disconnected, avoided vertically lapped limit fully and the underseal of secondary package and/or closedtop involution together.Vertically lapped limit part involution can also prevent that vertically lapped limit is loosening and sagging throughout on underseal and/or closedtop.In fact, vertically lapped limit becomes flexible or the sagging storing that can disturb secondary package.
According to the present invention level package spare is packed as previously mentioned and can also be reduced the necessary packing cost of level package spare that loading and unloading, storage and transportation have been feeded.And according to the present invention level package spare being packaged into secondary package is a kind of method of more easily carrying out, and this has also reduced manufacturing cost.
Preferably, osed top finished product secondary package is fallen the feeding section, and the osed top secondary package that the feeding section will be equipped with the bag of having feeded places the secondary package position of piling formation tray one by one.Have now found that, be packaged into bag and sign indicating number not luming substantially according to granular or detergent powder of the present invention in secondary package on another; Therefore, washer solvent is non-caked does not agglomerate into insoluble yet.Preferably, between the transportation unit of piling, place tie-plate (tie sheet).Friction between the transportation unit of tie-plate increase piling.Therefore, tie-plate can stop transportation unit at one any slip to take place on another during piling substantially, thereby increases the stability of tray.
When one of transportation unit on another during piling, stoping its other possibility methods that any slip takes place substantially is that part outmost surface to secondary package applies sicker or adhesives, perhaps secondary package is made with embossed film.Sicker or adhesives can be sprayed onto secondary package to the small part outside face.The method of preferably making embossed film is, is transported at film before the moulding shoulder of VFFS machine, and skidproof recessed pressure limiting flower is made in some zone at least of the film of secondary package.In order further to improve the stability of tray, embossed film and above-mentioned tie-plate can be combined use.In addition, particularly, can use,, and make whole tray further stable for example around the elastic film of tray parcel in order to transport.
The tray of Xing Chenging can save any other outer container that bears from the pressure of stacking fabricate block as previously mentioned.Like this, on total amount, saved the cost of the packing that the tray that is suitable for storing and transporting for formation uses greatly.And waste material also significantly reduces.In fact, outer container can not re-use usually, but handles simply.Have been found that according to tray of the present invention when comparing, can reduce by 50% waste material at least, preferably reduce by 80% waste material at least with the tray that uses corrugated board to make outer container.
