The method is characterized by the step of passing a portion of the web, being longer than at least the length of one package, past the jaws, the packaging material being without content, whereby the weight of bypassed packaging material makes the packaging material self-releasing from the jaws during initial start-up.

Description

A kind of method that is used for wrapping machine
Technical field
The present invention relates to be used for a kind of method of wrapping machine, use therein packing do not have any elastic afterworking or only have very little elastic afterworking.More precisely, the present invention relates to a kind of a kind of method that is used in processing by the wrapping machine cranking cycle of slim " non-resilience " tubular packaging material of paper in reel supply.The very light in weight of this material, and when the initial point of one-period before or after a last dead period begins, this material is during described cranking cycle or be introduced into, perhaps be between the transversal heat seal folder of described machine, cling described clips easily with empty package state or half occupied state.
Background technology
The packing of producing is made by extremely thin, the homogeneous material that will be sealed by vertical and horizontal or the paper in reel of laminated material.Produce a kind of technology definite and known, that be used for making packing that adopts from the smooth material web of supplying with by roller.Usually this material is sealed by topical application temperature booster in machine.But when this technology of use,, material produced some problems owing to clinging the heat-sealing folder easily.Although done very big effort aspect the thinner new material in that this known technology is applicable to, adhesion problems still exists.Because its weight of thinner new material is also lighter.The previous material that uses is owing to its thickness has a bigger self-stiffness.Existing studies show that is that the combination between less rigidity and the lower weight has caused the above-mentioned particularly adhesion effect during the machine start program.
Summary of the invention
So, one object of the present invention provides a kind of method, can easily handle empty package and half packing, and solve at cranking cycle arbitrarily packing are carried out initial horizontal to the leak free problem, material clings easily and is used for to the packing heating and with its heat-sealing that is sealed folder during any cranking cycle of indication herein.
Another object of the present invention is to find and provide a kind of method that is used to improve the machine sanitary condition, by this method during halted state, the product that carries out above the clips system washes and overflows the waste problem through the product of packing filling and distribute usually and all can be resolved, and the described product that normally overflows also can be imported packaging process once more.Its way is at the zero defect of the described capacity of packing inner packing that the internal side planar defect is arranged and clean product.Its advantage is the purification run that can save costliness and lose time, and the result at least theoretically can increase productivity.A result who saves the product flushing parts of machine is, this machine can not be designed the imaging today of in fact very incompetent type in purification process more in the future.
Can address this problem by method of the present invention, this method comprises the steps: to make the part of the paper in reel of the length of being longer than a packing to pass through clips, packing do not have content, by the weight of packing along separate routes these packing are broken away from voluntarily during initial start from clips.
Brief Description Of Drawings
Below with reference to accompanying drawings the preferred embodiments of the present invention are described in detail, wherein:
Figure 1 shows that the transparent view of a wrapping machine part, wherein the paper in reel of supplying with from roller forms the longitudinal type pipe continuously, to this pipe carry out the vertical and horizontal sealing with form packing and
Figure 2 shows that the diagram of circuit of a series of measures of taking by consecutive order since any initial point.
The specific embodiment
As shown in Figure 1, the method according to this invention is primarily aimed at wrapping machine, and its packing that will form forms by being designated as material web A, that supply with from the roller (not shown).Described material web A partly is made into tubulose at the B of machine, and is vertically implemented the sealing (not shown) in an overlapping junction along it in this step.Next, along the manufacturing line of machine, more precisely at the C place, current tube of material is injected into product.Its way is the tubular packing of double transverse sealing and encases the product that needs filling betwixt.Transverse sealing always carries out under the product liquid level that is being injected into during the normal running of machine.Like this, the involuntary stoppage of machine will be right after after the adjustment program, thereby avoids unnecessary product waste.How at the lowermost part D of Fig. 1 the packing that is filled is shown is cut into part and breaks away from machine.
Figure 2 shows that machine process flow chart that for example begin from first start behind whole place in operations, the process stabilized conditions, wherein packet assembler can run without interruption a few hours and need not to stop machine comprehensively.The situation that described diagram of circuit also only needs a temporary term stop to safeguard in the handling machine.Starting state (step 1), the packing that the mentioned kind machine adopts this starting to be filled with production at first are described.Whether step 2 is moved needs do not have the former of operation thereby fixed according to machine, if this reason only is an interim measure, wherein the heat-sealing of machine folder (step 2) must be started by short-term so that discharge the material that keeps on the machine, then operation, if machine cuts out for a long time, for example the longer intercourse between twice conversion is safeguarded, during this period of time described heat-sealing double-layered quilt discharges and therefore can not adhere on the packing, does not then move.After this part of bobbins of packaging material paper is by heat-sealing folder (step 3).The length of this part is at least a package length, preferably about 2-5 rice.Relied on its weight just can break away from the heat-sealing folder voluntarily by packing along separate routes, this will guarantee the elastic stress near the branch pipeline material of heat-sealing folder.
After approximately having supplied with 2 meters, in this case, the packing that machine is produced can be in and general different lower aseptic level.Only have the smaller portions packing must be before the packet assembler that comprises heat-sealing folder be started under the heat-sealing folder process, adhere to situation on the heat-sealing folder with the material of avoiding occurring early illustrating.After nearly 5 meters material is through the heat-sealing folder, in this case, before producing, the starting packing can guarantee higher aseptic level.Before filling beginning, sterilize by the mode of dispersing in the pipe such as bactericidal agent (as hydrogen peroxide).After the sterilization of the step before the packing, can carry out described long supply, to guarantee pipe asepticize before beginning filling.(before step 5) begins, pipe is made initial transverse sealing (step 4) at to-fill procedure.Sealing is double seal, and double seal is not necessary, but it depends on the design of clips system, and this system is designed to twice sealing so that cut betwixt, makes individual packages disconnected from each other.Behind the beginning to-fill procedure, the pipe of fill system more or less all is empty, is full of filtrated air.Thereby if begun the normal running (transverse sealing and cutting) of machine, just the product quantity in the packing can be uncontrollable.For avoiding this problem, packing are other through (step 6) arrives on the level of described clips up to the product level of being filled in clips.Do transverse sealing for the second time then, the normal running of beginning machine, the sequential lateral that promptly begins to continue seals and same sequential lateral cutting (step 7).The uncontrollable product of quantity is wrapped up between first and second time transverse sealing of formation long " packing " together.This long " packing " separates from machine, and the product of the inside can be returned to-fill procedure (repeating no more) at another position herein.After this, produce with stabilized conditions operation (step 8).
The stabilized conditions production period whenever all something might take place, thereby the halt instruction (step 9) that need start the machine.When this thing happens, the packaging and cutting program of order operation interrupted at first temporarily that (step 10) is done for the second time (dual) transverse sealing (step 11) at last under liquid level.After this stop to-fill procedure (step 12).The filling pipe of still possessing large-tonnage product begin to the tubulose that is forming " packing " discharging about 10 second (step 13).Because stopping of transverse sealing and cutting operation, formed " packing " is longer than the packing of ordinary production.After filling tube drainage, control heat-sealing folder is done final dual transverse sealing (step 14), but this is once unique on liquid level.(elongated tubular that step 15) forms in proper order " packing " is finished shut down procedure by cutting afterwards.Present machine is dead stop, and all systems all are stopped, but still are in readiness for action.But produce in order to restart after temporary term stop, the supply of packing does not stop, and the quantity of supplying with up to wherein (according to step 2) has been right after under the heat-sealing folder.
It should be understood that the present invention is not limited to above-mentioned preferred embodiment, but do not break away from the scope of appended claims.
