Technical field
The invention belongs to the field of the packing technique of plastic sheeting, particularly detection, the contact pressure of correction sealing element and film further carries out the leak free apparatus and method according to suitable contact pressure.
Background technology
When carrying out the automatic filling and packing of content, for example, banded plastic sheeting is rolled at Width, intersection to it seals the formation cylindrical body, filling content therein, secondly, if the column packaging body is then implemented transverse sealing on each certain intervals of length direction of film, cut off in this transverse sealing position simultaneously, if the packaging body of two ends ligation then carries out ligation to two ends on each certain intervals of length direction of film, between adjacent ligation becket, cut off simultaneously, obtain each packaging body.The sealing of above-mentioned coincidence part office is called vertical sealing, when the filling content, because be subjected to internal pressure from this content, so sealing must be infallible and have high strength.
As the leak free method, have the high-frequency heating sealing that causes by high frequency waves, ultrasonic sealing, heated sealants etc. all are film to be clipped between the sealing element of electrode etc. with decided contact pressure to carry out leak free in which kind of encapsulating method.At this moment, it is extremely important can making contact pressure maintain on several institutes definite value, and this has very big influence to sealing intensity.
So, always all be the condition of considering by film self, all conditions that the operating condition of device or environmental conditions etc. provide are set and are thought best contact pressure, seal on the basis of this contact pressure.
But, in fact, even if consider the condition of film self fully, because operating condition or environmental conditions change gradually in seal process of device, so must set contact pressure under the New Terms according to reason in this case.But, when carrying out automatic filling and packing,, device will be shut down, thereby reduced productivity significantly for contact pressure is set again.
Again, present situation is, when sealing, because whether change is not judged to contact pressure, so, after carrying out encapsulation process on the basis of deciding contact pressure, need to check out the new inspection operation of defective packing body in the inspection afterwards in order to make packaging body poor sealing not occur as far as possible.Therefore, many being in because the packaging body in the state of internal pressure before hermetic unit breaks of content can appear.Like this, even if, conclusive defective products can not take place as far as possible, also do not take any relative measures in order there to be the situation that leak free intensity reduces and stability reduces yet.
Summary of the invention
The objective of the invention is,,, also always can under deciding contact pressure, seal like that, detect, revise seal contact pressure, and carry out the leak free apparatus and method even if be provided for the changes such as operating condition of device in view of this present situation.
Our method that will be used to solve this problem is listed below now:
The seal contact pressure detecting device of a kind of film of the present invention, it is characterized in that: apply contact pressure by one side intersection that follows away the direction extension to the plastics made membrane of constant speed walking between a pair of sealing element that forms by fixed parts and movable member, one side is carried out longitudinal sealing from this movable member to this intersection energize, thereby can moving to the fixed parts direction, this movable member can change contact pressure, movable member has the force transducer as the contact pressure detecting device, above-mentioned detection device with relatively detect contact pressure and decide with predefined that contact pressure produces the shows signal of difference of two contact pressures or the indicating device that sends warning signal during above allowed band when this difference is connected.
According to aforesaid the present invention; often or in due course the phase demonstrates seal contact pressure by indicating device; perhaps when and decide contact pressure difference between the contact pressure and give a warning by indicating device when surpassing allowed band, the operator revised contact pressure in this moment.So, before producing poor sealing, just can take the measure that prevents trouble before it happens.
The seal contact pressure method of inspection of a kind of film of the present invention, it is characterized in that: apply contact pressure in the intersection that follows away the direction extension when the plastics made membrane of between a pair of sealing element that forms by fixed parts and movable member, walking to constant speed by one side, the one side from this movable member when this intersection energize carries out longitudinal sealing, thereby this movable member can move in the method that can change contact pressure to the fixed parts direction, the force transducer as the contact pressure detecting device that is had by movable member detects contact pressure, demonstrates relatively to detect contact pressure and predefinedly decide the difference of two contact pressures that contact pressure obtains or send warning signal when this difference surpasses allowed band.In addition, often can revise, there is no need device temporarily to be shut down in order to revise.
When intersection is sealed, in the present invention, on the film direction of travel, both can make seal contact pressure constant, also can make the seal contact pressure change.
Description of drawings
Fig. 1 is the summary pie graph of an example device of the present invention.
The specific embodiment
Below, we are according to description of drawings example of the present invention.
Fig. 1 is the figure that the summary of the sealing arrangement of this example of expression constitutes.
This example device as being used for the leak free device, has a pair of electrode 1,2 that is used to carry out electronic heating.One side's electrode 1 is arranged on the fixed parts 3, the opposing party's electrode 2 is arranged on the movable member 4.
Fixed parts 3 is made the cylindrical body of hollow, and top has the annular flange dish 3A that is called the size ring that is used to guide film, and an above-mentioned side's electrode 2 is being arranged on the fixed parts 3 like that extending on the axis direction on the three unities of circumferencial direction
On the hollow space of the fixed parts 3 of making above-mentioned cylindrical body, movably insert the nozzle body 5 that configuration is used for the filling content up and down.This nozzle body 5 has the annular flange dish 5A identical with above-mentioned annular flange dish 3A, 5B in its bottom.Like this, form barrel-contoured band-like film F by the unillustrated parts (shaping blade) that give shape among the figure, contact like that with the surface of above-mentioned electrode 2 by the intersection F1 that makes it, guiding enters annular flange dish 3A, 5A, 5B keeps barrel-contoured shape invariance with constant speed A walking downwards.
To the movable member 4 of the opposing party's electrode 2 be installed, in the situation shown in the figure, make roughly L word shape, being positioned at upper end axle 6 nearby can support freely to rotate.On this movable member 4, contact pressure correcting device 7 is installed.This contact pressure correcting device 7 is above-mentioned movable member 4 can be pressed to left and can change electrode 2 to constitute like that for the contact pressure of electrode 1.Both can manually produce the intensity of pressure and this pressure of setting of pushing movable member 4, also can automatically carry out by the signal that receives from the described control setup in back.For example, in manual situation, can be by screw screw-in amount, in situation automatically, can be by determining the amount of movement of this direct mobile key element of amount of movement to realize pro rata with the electric signal amount.Usually, add to the right the power of (around the anticlockwise of axle 6) with spring etc. on movable member 4, above-mentioned contact pressure correcting device 7 these spring forces of resistance move movable member 4, thereby change the contact pressure of above-mentioned electrode 2 for electrode 1.
On above-mentioned movable member 4, be provided as the force transducer 8 of contact pressure detecting device, when electrode 2 was subjected to antagonistic force as contact pressure, force transducer 8 produced and the proportional electric signal of contact pressure according to the elastic deformation of the movable member 4 that this antagonistic force causes.Therefore, the corresponding value that can try to achieve the contact pressure of detection with the value of this electric signal.
Above-mentioned force transducer 8 is connected with the amplifier 11 of control setup 10.Control setup 10 has amplifier 11, A/D changer 12 and instruction device 13, and the signal of above-mentioned force transducer 8 (contact pressure of detection) after amplifying, is transformed into digital value by A/D changer 12 in amplifier 11, be transferred to instruction device 13.
Above-mentioned A/D changer 12 will through digitized detect the contact pressure value intactly be transferred to telltale (not drawing among the figure) produce like that output 14.Again, also can to A/D changer 12 from external setting-up as the allowable upper limit value of contact pressure and lower limit decide contact pressure value 15.
At instruction device 13, acceptance from above-mentioned A/D changer 12 detect the contact pressure value and decide the contact pressure value, both are compared, should detect the contact pressure value and enter the direction of being decided in the scope of contact pressure value and make 7 actions of contact pressure correcting device like that along making, send instruction to this contact pressure correcting device 7.At contact pressure correcting device 7, produce actuating quantity accordingly with this command value, mobile movable member 2 changes contact pressure.
Secondly, we illustrate this example device action.
(1) in this example device, makes band-like film F be rolled into tubular with shaping blade, and intersection F1 is clipped between the electrode 1,2, in the direction of arrow A walking.When walking, become barrel-contoured film F owing to annular flange dish 3A, 5A, the guiding of 5B keeps barrel-contoured shape invariance.
(2) in the contact pressure correcting device 7 of the movable member 4 of pushing supporting electrode 2, consider the sliding of above-mentioned film, tension force, the environmental conditionss that thickness and device cause etc. are set and are thought best contact pressure.But after the device running, actual contact pressure can depart from setting value.The reason that generation departs from mainly is the variation of establishing timer-operated electrode desired location that device vibration etc. causes.
When contact pressure changes, detect this variation by force transducer 8, will with detect the corresponding electric signal of contact pressure value and be sent to control setup 10.In control setup 10, with amplifier 11 this signal is amplified, carry out digitalisation as contact pressure with 12 pairs of these signals of A/D changer.Produce this digitized contact pressure as output 14, and on the telltale (not drawing among the figure) of the suitable position that is arranged at device, show.By this telltale, the operator can at any time know instantaneous contact pressure.
(3) on the other hand, will be with A/D changer 12 through detecting the contact pressure value after the digitalisations, with decide contact pressure value 15 input instruction devices 13 from outside input digitized, calculate and detect contact pressure value and the decide difference of contact pressure value, should make the contact pressure value enter decide the command signal that contact pressure value scope makes contact pressure correcting device 7 move like that and be sent to this contact pressure correcting device 7.This command signal is proportional with above-mentioned difference, and 7 actions of contact pressure correcting device and this command signal are measured accordingly.Like this, make the contact pressure of electrode 1,2 enter in allowed band decide in the contact pressure scope, according to suitable contact pressure, the intersection F1 of film is sealed.
(4) from said nozzle body 5 with content-filled to the film cylindrical body that forms sealing (vertical sealing) at intersection F1.Then, if the column packaging body is then implemented horizontal sealing on each certain intervals of length direction of film, cut off in this transverse sealing position simultaneously, if the packaging body of two ends ligation then carries out ligation to two ends on each certain intervals of length direction of film, between adjacent ligation becket, cut off simultaneously, obtain each packaging body.
The present invention is not limited to graphic example, can carry out all distortion.
For example, the formation as device can not have instruction device 13 yet, only demonstrates to detect contact pressure value and decide the poor of contact pressure scope on the telltale as read out instrument.Show that according to this operator can implement suitable correction by enough contact pressure correcting devices 7.At this moment, contact pressure correcting device 7 has manually operated formation.
Secondly, the detection key element of contact pressure detecting device, except force transducer, also can use deformeter, detected pressures such as piezoelectric element are as electric signal, detection of the detection of this bounce pressure that can cause from the spray pressure fluid or this contact pressure that caused by contact pin etc. is come out as electrical signal detection, perhaps can be without pressure but the change in location of detecting electrode obtain and its corresponding contact pressure value.
Again, sealing arrangement of the present invention does not limit the form of sealing self, for example, can be the subsides of putting the palms together before one, and envelope tube subsides etc. are used for the leak free device then, except carrying out with existing high frequency waves the sealing of high-frequency heating, also are applicable to ultrasonic sealing, heat seal etc.No matter in which kind of situation, because the intersection of film is sandwiched between 2 sealing elements and adds suitable contact pressure, thus can detect this contact pressure according to the present invention, and revise.
Further, as above-mentioned contact pressure correcting device, the device of pushing movable member can be by motor, cylinder, and the form of contact pressure is automatically revised in the work of screw actuator etc., determines the actuating quantity of these action elements by control setup.
Further, also can make contact pressure on the film direction of travel, keep steady state value to seal like that, but by obtaining the change value on same direction, also can access the sealing form with the weak contact pressure part of strong contact pressure partial sum.
Because the fixed parts of the sealing element when the present invention detects as sealing and the contact pressure between the movable member, making this contact pressure be in institute's definite value (in the scope) revises like that, so the intersection of film always can access best sealing condition, can occur hardly because the situation that unfavorable condition stops device taking place, thereby improved the work efficiency of device, on the other hand, become the good product that sealing stay in grade and intensity are fully guaranteed as the packaging body of goods.
