Background technology
In medical field, use the polybag of common form as bag film.It is used to many aspects.Polybag can be used for accommodating parenteral solution, also can be used for the medicinal liquid of storing blood (storage blood) and sterilization.Polybag needs filling and the draw-out device that is configured to so-called port.Polybag can have one, two or more port according to application target.Each port can have specific moulding and/or independent structures part according to the occupation mode of setting.
For example, document DE19634944C1 and DE19958952A1 disclose the method for the port that is used for making polybag.The manufacture method of describing in the document is, a whole plug-in unit that is made of plastics is solded in the fringe region of the polybag that the plastic sheeting by two superimposed constitutes.This plug-in unit is made of an enough big solid plastic object of cross-sectional area, so just can settle one, two or more port that has cylindrical through flow cross section separately selectively in plug-in unit.
Port in the polybag can adopt dissimilar plastic components to realize.Plastic components can form for example constitute by polypropylene, have or not with the extrusion molding flexible pipe of EVA internal layer.Plastic components also can form the moulding that for example is made of polypropylene.
The manufacturing of polybag adopts a kind of like this manufacture method to carry out in a known way, promptly, the two-layer plastic sheeting that will be welded to each other is transported to a welding/cutting die, this welding/cutting die can be single with or use more, that is to say that its mold shape can be at one or more polybag designs.With the conveying of the plastic sheeting that is welded to each other is to carry out with the form of parallel plane, overlapping continuous plastic sheeting, plastic sheeting is left behind from the film volume without cutting or along track cutting ground as the continuous hose of blowing usually continuously, and by means of dancer maintenance extended configuration, wherein, guarantee by known device (for example by film folder): the delivery end position of plastic sheeting accurately is positioned the input of welding/cutting die of being made of two half module tools.
Two half module tools separate subsequently, and plastic sheeting passes the mould of unlatching.For this reason, vacuum aspirator runs through the mould of unlatching usually, and catch plastic sheeting accurately to be positioned at delivery end on the mould input, and the mould that passes unlatching is moved this delivery end to output always, then, at two half module tools near in the process of (closure) or soon afterwards, between plastic sheeting, form weld seam, it is accurately corresponding with the shape of polybag on profile, simultaneously freely cut polybag by means of the separating knife that is contained in welding/cutting die, and be still new (not welding) plastic sheeting and separate, thereby the delivery end of new plastic sheeting is positioned on the input of welding/cutting die.
Described manufacture method is being optimized aspect the details of processing procedure and equipment that for this reason uses and device time and again.But, in the manufacture process of polybag, raise the efficiency significantly with but failing up to now.The sequential of single welding and cutting method step, finished product polybag position are handled operation, the filling of polybag in case of necessity and sealing accurately and are wished that polybag is inserted the situation of sealing in the bag all fails to change.
Summary of the invention
The objective of the invention is to, improve the manufacturing of polybag by new or improved device.
This purpose and other purposes all realize by the present invention.
The device that the present invention is used to make the polybag that is made of plastic sheeting comprises one or more membrane supplying devices, in order to plastic sheeting to be provided; One or more port feeders are in order to provide port; A combined welding/cutting die is in order to be installed to port on the polybag, to be welded on plastic sheeting on one pattern and to cut plastic sheeting; Another weld mold is in order to weld port again; And a transfer station, further process in order to receive polybag.Membrane supplying device, port feeder, combined welding/cutting die and transfer station are combined in the device, have simplified manufacture method, and make the structure of device become compact.
In a preferred implementation of this device, the plastic sheeting in combined welding/cutting die is level basically.Arrange this device like this, just can especially simply plastic sheeting be inserted in combined welding/cutting die.Plastic sheeting can be positioned on combined welding/cutting die because of its gravity open and flatly.
This device can be equipped with the preheating station of a plastic components.The preheating station that this plastic components has been arranged, plastic components just can reach higher temperature before welding step.Just the welding of plastic components and plastic sheeting can be simplified and accelerate thus, and temperature stress can be reduced.
In a preferred embodiment, this device comprises a film printing unit.Adopt this film printing unit, just can print, thereby can on polybag, stamp the information in the material of related content thing, polybag, the suitable time limit of polybag etc. plastic sheeting.The film printing unit can for example be arranged in the back of one or more membrane supplying devices.
A preferred implementation that is used to make plastic bag device has a kind of like this structure, that is, in combined welding/cutting die, respectively two plastic components are installed on two polybags simultaneously.With regard to transmitting with the operation of two polybags of two plastic components respectively, the device of this manufacturing polybag has obtained optimization.Such structural design makes the structure of making plastic bag device become compact, has improved output simultaneously.
This device that is used to make polybag can comprise a sack filling machine, to load a kind of liquid to polybag.By sack filling machine being combined in this device, can further simplify manufacture method.Just can avoid transfer and the transmission outside device of the polybag made thus, it must carry out in a better purifying space by the salubrity study plot usually.
In a preferred embodiment, sack filling machine is equipped with the filling device of polybag, the relief groove and the bag involution station of liquid.By this relief groove, liquid can be remained on consistently under the higher pressure of possibility.Through Open valve, liquid can be quantitatively packed in the polybag by filling device.In same better purifying space, utilize a bag involution station that polybag is carried out involution, can allow the content in the bag keep clean.This involution for example can assemble or be welded on the port and carry out by blocking a shot.
Behind combined welding/cutting die, a tumbler can be inserted the device that this is used for making polybag.This tumbler can allow polybag turn to the upright position from horizontal level, and this helps giving the polybag loaded with liquid in the filling station.
Can install one additional to this device that is used to make polybag and seal bag package machine.Seal in the bag package machine available one deck plastic protective film packing plastics bag at this.This plastic protective film is provided by one or more second membrane supplying devices.By with plastic bag packaging to sealing in the bag, can health reliable and provide protection ground to transmit and place polybag.The port of the polybag that for example can preventing makes dirty makes.
This simplification that is used to make plastic bag device realizes by a weld mold, it comprise one actionless, be the following weld mold plate and a last weld mold plate activity, moulding on plane basically.A kind of like this weld mold can easily be pulled through down plastic sheeting the weld mold plate.This time weld mold plate should be the plane especially in the residing zone of plastic sheeting.The following weld mold plate on this plane manufactures simple and favourable, and cleans easily.Actionless parts have improved the service life of equipment.Actionless parts can be used for the structure and the stabilisation of whole device.Utilize last weld mold plate this activity, moulding, can push multilayer plastic film.Welding region can be limited by the shape of last weld mold plate.By making the weld mold sheet metal forming, also port can be solded in the polybag.
Cutting die also possesses similar advantage, it comprise one actionless, be the following cutting Die and mould plate and a last cutting die plate activity, moulding on plane basically.Be molded over this and mean especially, the separator of blade or other types is positioned on the cutting die plate.
Because combined welding/cutting die has been arranged, just further simplified the device that is used to make polybag, wherein, combined welding/cutting die comprise one actionless, be the bed die plate and a mold plate activity, moulding on plane basically.Only need a mould just can implement welding and separation steps.The quantity of movable part in mutual contact further reduces.Equipment size dwindles.Equipment cost has also reduced, because only need a mould to come the extruding plastic film, it can weld and cut plastic sheeting subsequently simultaneously.
Advantageously, the bed die plate in combined welding/cutting die is made by hard steel or hardened steel.Just can improve the service life of plate thus extraly, so only need to change the bed die plate seldom inferiorly.
Advantageously, the bed die plate has a plug-in unit in plastic components is installed to zone on the polybag.This plug-in unit can heat separately and change.This plug-in unit can be made by a kind of material that is different from the bed die plate.Plug-in unit can comprise a depression, with the height of compensation plastic components when combined welding/cutting die is collided.Because this plug-in unit has been arranged, it is easy that the extruding of plastic sheeting just becomes.Simplified the welding of plastic components on the polybag in the adjustment of separately carrying out on the plug-in unit.The temperature of plug-in unit can be higher than the temperature of bed die plate.
In addition, the zone that the service life of bed die plate can be by the mold plate especially the soft material in the separator improve.At this, the mold plate is installed in such a way, that is, the monoblock upper plate is easy to change, and perhaps the preferable separate device is easy to change.
At the device that is used for making polybag, welding process can be because of being improved in order to the weld mold of connection two layers of plastic thin films or the special design of combined welding/cutting die.This weld mold or combined welding/cutting die comprise the following weld mold plate or a bed die plate and a last weld mold plate or the mold plate that adopts second temperature that adopt first temperature.This first temperature is lower than the softening temperature of plastic film material.Just can heat thus, and can not take place bonding with lower plate to plastic sheeting.Second temperature at least temporarily is higher than the fusion temperature of plastic film material at least in the subregion of last weld mold plate or mold plate.Because second temperature at least temporarily is higher than the fusion temperature of plastic sheeting, thereby realized the connection of multilayer plastic film interlayer.
In a preferred embodiment, first temperature keeps constant in time substantially.The first constant temperature realizes easily, and can not have and regulate difficulty ground becomes to be lower than plastic film material with first adjustment softening temperature.
First temperature can be regulated on same degree ground on the sizable zone of bed die plate.Uniform heating can adopt the standard heating element heater to carry out, and need not consider the shape and the position of desirable welding region.At this, another kind of feasible program is only to heat the zone of carrying out welding process in the bed die plate.This has just further reduced plastic sheeting and the bonding situation of bed die plate.First temperature also can be regulated on the bed die plate on substantially constant ground on the when and where.
Second temperature equally also can be held in the fusion temperature that is higher than the plastic sheeting material therefor in time consistently.Also just simplified adjustment thus.It is constant that second temperature also can keep in the zone of mold plate substantially partly.But the separator in this will allow combined welding/cutting die for example especially, the zone of cooler are lower than softening temperature.
Combined welding/cutting die has brought advantage for the enforcement of method of operating of the present invention, that is, transfer system is caught a no pattern voluntarily and is the bed die plate on plane in mould when plastic sheeting passes the mould of unlatching, and this plate does not hinder the transmission of film.The transmission of film can not be subjected to the obstruction that plastic sheeting adheres to, because this bed die plate is " cold ".In the present invention, term " cold " is meant that the bed die plate for example remains under the state of temperature that is different from hitherto known weld mold state of temperature by temperature detection and guide suitable, that press close to the surface installation.In fact, up to the present finally still to consider the softening or fusing situation of plastic sheeting to be processed.In the present invention's's " cold " bed die plate, avoided the softening temperature of " cold " state on bed die plate surface thus well below plastic sheeting to be processed, plastic sheeting just can not stick on the bed die plate like this.Plastic sheeting dimensionally stable and mobile being positioned at well on the bed die plate.
Because plastic sheeting dimensionally stable on the bed die plate of plane and " cold ", the size of made polybag also is quite accurate.
The method step of welding, cutting or Combination Welding, cutting step can become effective by transfer system of the present invention.This transfer system can be along cutting die, weld mold or the combined type cutting/weld mold process of closure.When the process of welding or cutting was still continuing, plastic sheeting was transmitted system and clamps before cutting die, weld mold or combined type cutting/weld mold.This transfer system can be drawn in one or more layers plastic sheeting in cutting die, weld mold or the combined type cutting/weld mold of unlatching.
This transfer system is preferably first and/or second clamper, and they are along the side process of cutting die, weld mold or combined type cutting/weld mold.This first clamper and/or second clamper can be designed to manipulator, and it clamps one or more layers plastic sheeting.This transfer system also can be realized by vacuum aspirator or roller.
In another preferred embodiment, cutting die, weld mold or combined type cutting/weld mold are provided with recess, when cutting die, weld mold or combined type cutting/weld mold were closed, first and second clampers still can be fixed this one or more layers plastic sheeting like this.By the recess and first and/or second clamper are set suitably, just can allow plastic sheeting be fixed on down the weld mold plate open and flatly, cut on Die and mould plate or the bed die plate down.
By the embedding seat on the driving-belt on the device of making polybag, can further improve the method for making polybag.This embedding seated connection is received plastic components and be delivered to weld mold or combined welding/cutting die.Plastic components still is fixed in the embedding seat in welding step or welding/cutting step.Polybag can take out from combined welding/cutting die by the plastic components in being fixed on the embedding seat behind welding/cutting step.
For polybag is loaded, in a preferred embodiment,, adopt a filling station with respect to the polybag that has two ports at least.Be the problem of avoiding becoming to drip, although and also can be enough accurately quantitative under the situation of filling at a high speed, by many input pipes the polybag that has a plurality of ports is loaded.In the case, according to the present invention, these input pipes lead to a proportional valve, and seal many input pipes by the valve plug of a public film.
