The specific embodiment
Air-packing device of the present invention is described in detail with reference to the accompanying drawings.Though should be noted in the discussion above that purpose for example, it is the air-packing device inflation that the situation that the present invention describes is to use compressed air, also can use such as the gas of other types or other fluids of liquid.Flow through in the journey in the distribution of product, described air-packing device typically is used in the container with packaging product.
Air-packing device of the present invention for packing such as hard disk drive, PC, DVD driver, bottle, glassware, pottery, stereo set, oil painting, antique etc. to vibrations or shake responsive product, particularly useful.Described air-packing device can be packed these products and their annex reliably after the compressed-air actuated inflation of process.Typically, the air-packing device of packaging product and annex thereof is installed in the container.Air-packing device of the present invention has particular structure, is used for easily tearing after use discharging air.
Air-packing device of the present invention comprises a plurality of air chambers, and each has check-valves and a plurality of air element that are connected continuously.Air chamber is spaced apart with other air chambers airtightly, and the air element in same air chamber is interconnected by air duct, thereby air can flow between air element by air duct.After air was packed into air chamber, each air element in the air chamber had the same shape of sausage.
Described air-packing device generally includes two-layer (upper and lower) thermoplastic film.Check-valves in these structures is to use the check valve membrane that is placed between upper strata (first) thermoplastic film and lower floor (second) thermoplastic film.When compressed air filled in the air-packing device, air will be pushed check valve membrane, and closure of check ring is to prevent the reverse flow of air by this way.Because each air chamber has check-valves to prevent reverse air flow, so described air-packing device also keeps inflation after use.Therefore, each and all air chambers must be punctured in some way or tear and discharge air, thereby described air-packing device can be deflated.
Fig. 1 is a stereogram, has shown the air-packing device 40 with a plurality of air chambers, and venting sheared edge of the present invention therein can advantageously be implemented.Described air-packing device 40 comprises a plurality of air chambers 42.Check-valves 44 is set on each air chamber 42, to prevent the reverse flow of air in air chamber 42.Compressed air is injected into each air chamber 42 by air guide passage 63 from air input 41.Venting sheared edge 401 is arranged near the respective non-return 44.
Air-packing device 40 is made up of the upper and lower thermoplastic film, and they combine at partition seal 46 places, so that air chamber 42 is spaced from each other.The one or more thermoplastic film that is used for check-valves 44 is arranged between the thermoplastic film of the upper and lower, and this will describe in detail afterwards.Fig. 1 shows the state after air-packing device 40 is compressed the air filling.
As shown in Figure 1, each air chamber 42 is provided with check-valves 44 to prevent compressed-air actuated reverse flow.One of main purpose that a plurality of air chambers that have a check-valves are set is to increase reliability, because each air chamber and other air chambers are separate.That is to say that leak even an air chamber is subjected to air for a certain reason, because other air chamber is intact, the function that described air-packing device also can be carried out attenuator is used for packaging product.
Yet after air-packing device 40 used, for compressed air is discharged in air-packing device 40, it was not enough only puncturing an air chamber, because other air chambers are still preserved air owing to be arranged on the check-valves 44 in each air chamber.The stereogram of air-packing device 40 only is a simple embodiment among Fig. 1, and the present invention also may be used in the air-packing device with a plurality of air element of many other types.For example, as described above, each air chamber can be marked off the air element of a plurality of continuous connections again by heat-seal areas, thereby described air-packing device can easily be folded into complicated structure, and this will describe in detail subsequently.
Now, the process of exitting will be described from have the air-packing device according to venting sheared edge of the present invention.Fig. 2 A is a vertical view to 2C, has shown to have the exit air-packing device 40 of sheared edge 401 of the present invention.Each air chamber 42 is spaced from each other by partition seal 46, and has a plurality of air element 42 that demarcated by heat-seal areas 51.Sealing area 72 is arranged between the adjacent air chamber 42.In described embodiment, each sealing area 72 partly forms as the enhancing of check-valves 44.At each sealing area 72 place, all layers of thermoplastic film mutually combine.
Venting sheared edge 401 is formed in the sealing area 72, and directed on identical direction each other.Typically, venting sheared edge 401 is positioned at sealing area 72 places, moves towards on the direction vertical with the longitudinal direction of air-packing device 40.Venting sheared edge 401 is to cut the opening completely of all layers of thermoplastic film.Because all thermoplastic films are in sealing area 72 places combination, and venting sheared edge 401 is formed in the sealing area 72, and the air in the air chamber (air element) 42 can not leak in the normal state.Therefore, venting sheared edge 401 can not have influence on the function of air-packing device 40.Preferably, each venting sheared edge 401 is extended between two adjacent air chambers 42.
Fig. 2 A is a vertical view, has shown to have the exit air-packing device 40 of sheared edge 401 of the present invention, and wherein air-packing device 40 is filled with compressed air, that is to say that it also is not deflated.Yet simple in order to illustrate, the air-packing device 40 among Fig. 2 A-2C is represented in flat mode.Arrow A has shown the direction of the power that will apply, and described power is torn air-packing device 40 along the direction of venting sheared edge 401.
Above-mentioned power of tearing air-packing device 40 is preferably applied by user's hand artificially, but also can use other modes.As mentioned above, all venting sheared edges 401 are being arranged on mutually the same direction on the air-packing device 40.For the ease of the initial process of tearing, each limit of air-packing device 40 is provided with a semi cuts (incision edge) of venting sheared edge 401.As described in detail later, the semi cuts on this each limit (terminal part) that is positioned at air-packing device 40 will produce by the operation shown in 7A and 7B.
Along with insisting on continuous constantly being applied on the air-packing device 40, the bottom of air-packing device 40 begins to be torn shown in Fig. 2 B.Though at first only be arranged on that venting sheared edge 401 on the sealing area 72 is cut open and other positions are not cut open, in case apply the power of tearing, because the existence of venting sheared edge 401, the part that does not have to cut also can easily be torn under the help of linear impulse and direction.In other words, venting sheared edge 401 is guiding on the direction that predetermined tear edge applies and is tearing operation.In Fig. 2 B, because the part of leftmost air element 42 is torn, the compressed air in the leftmost air element 42 will therefrom spill.
Fig. 2 C has shown the situation that separate from main body fully the bottom of air-packing device 40.Therefore, although each has check-valves 44 to prevent reverse air flow in a plurality of air chamber (air element) 42, by tearing the bottom with hand, all air can easily eject from air chamber, thereby air-packing device 40 is exitted.Although in the above among the embodiment of Miao Shuing, the direction that is applied to the power on the air-packing device 40 shown in the arrow A is from left to right, described power also can form on the right of air-packing device 40 accordingly because of cutting edge (semi cuts), alternately to apply from right to left to above-mentioned similar mode.
Fig. 3 is a vertical view, has shown the embodiment of the detailed structure of air-packing device of the present invention in check-valves 44 zones.Mainly, air-packing device 40 is made of three layers of thermoplastic film; First and second (upper and lower) air-packing film 91a-91b and check valve membrane 92.Go up the basic configuration that (first) thermoplastic film 91a and following (second) film 91b have formed the air-packing device 40 with a plurality of air chambers.Each air chamber has the air element 42 of a plurality of continuous connections.Check valve membrane 92 in the present embodiment is made of sheet of thermoplastic film, and is that each air chamber 42 forms check-valves.
Air-packing device 40 among the embodiment shown in Figure 3 comprises a plurality of venting sheared edges 401, is positioned at the bottom section of check-valves 44 in the horizontal direction.Each venting sheared edge 401 forms in sealing area 72, and each extends described sealing area 72 between two adjacent air chambers 42.As mentioned above, sealing area 72 is such zones, and first, second and check valve thermoplastic films are by mutual heat seal therein.Because thermoplastic film is sealed airtightly, air can't flow into or flow out sealing area 72.And then when even air has been charged in the air-packing device 40, venting sheared edge 401 and sealing area 72 are flat.Thereby when needs were torn air-packing device 40 and are used for air discharged, the user can easily catch the zone of venting sheared edge 401.
Fig. 4 has shown the embodiment of the structure of the check-valves 44 in air-packing device of the present invention and the sheared edge 401 of exitting.With reference to the description of figure 3, the air-packing device 40 of described preferred embodiment is made up of the upper and lower (first and second) film and check valve membrane, and typically, described whole films are thermoplastic films.A zone of interosculating with check valve membrane in upper layer film and the lower membrane is expressed by hacures in Fig. 4.
In described embodiment, sealing area 72 has formed the part of check-valves 44, and contiguous with air guide passage 63.Sealing area 72 is set for the calmodulin binding domain CaM of strengthening between guide channel 63 and the air chamber (air element) 42, thereby prevents that air chamber is damaged when inflation.Partition seal 69 is that first and second thermoplastic films are combined with air chamber 42 and adjacent air chamber 42 isolated zones.
All thermoplastics (first, second and check-valves) film is heat sealed as described above at sealing area 72 places, and therefore, when compressed air charged in the air-packing device 40, sealing area 72 kept flat.Venting sheared edge 401 is arranged in each sealing area 72, and on identical direction, for example in Fig. 4, is directed on the direction that is approximately perpendicular to partition seal 69.Because all thermoplastic films are in sealing area 72 places combination, venting sheared edge 401 can leakage air.
When compressed air charges in the air-packing device 40, the flowing of air by arrow 77a, 77b, 77c and 77d represent.42 air flows through check-valves 44 and is conducted relatively reposefully from guide channel 63 to air element.In addition, be formed on the reverse flow that narrowed portion 67, expansion 65 and exit portion 73 in the check-valves 44 prevented air.Therefore, the reverse flow from air element 42 can not be passed through air hose 78 easily, and it has promoted air to charge into the process in the air-packing device.
Fig. 5 is a sectional drawing, has shown the effect of the check-valves 44 among Fig. 4.Described embodiment demonstration, when air-packing device is fully inflated, when tending to reverse flow takes place in it, the internal state of check-valves 44.In the present embodiment, check-valves 44 is formed by two check valve membrane 92a and 92b, and wherein check valve membrane 92b is attached on the first thermoplastic film 91a of air-packing device at its end.
When the air of q.s filled in the air element 42, because exit portion 71 and 72 overcomes the air running, thereby reverse flow can not enter into exit portion easily, and air is difficult to turn back in the air hose 78.Alternatively, as shown in arrow 66, to flow in the space of air between the second air-packing film 91b and check valve membrane 92a, described zone is inflated as shown in Figure 5.By this expansion in Fig. 5, check valve membrane 92a is pressed towards the right, and simultaneously, check valve membrane 92b is pressed towards the left side.As a result, two check valve membrane 92a and 92b such tight contact as shown in arrow 68.Therefore, check-valves 44 is fully closed by internal air pressure, thereby has stoped reverse flow.
Fig. 6 has shown the embodiment that is used to produce in conjunction with the process units of the air-packing device 40 of venting sheared edge 401 of the present invention and check-valves 44.Check-valves 44 and venting sheared edge 401 constitute in manufacture process.The structure of process units shown in Figure 6 only is embodiment, and those of ordinary skills can understand, and uses the notion of process units as shown in Figure 6, also has many other modes that are formed for producing the device of air-packing device 40.
For with respect to the upper and lower thermoplastic film 91a and 91b and accurately locate check-valves (check valve membrane 92), up-down rollers controller 84 is set on the process units 80.In order accurately to adjust the position of check-valves mould 92, up-down rollers controller 84 is (upwards or downwards) mobile roller 84b in perpendicular to the direction of making flow path direction H.Equally, in order to improve the heat seal performance, the plastic foil that at high temperature the has high mechanical properties belt conveyer 87 in its surface that has such as Teflon film or Mylar film is set.
With reference to figure 6, whole manufacturing process is described.At first, film feed arrangement 81 provides upper thermoplastic film 91a, lower thermoplastic film 91b and check valve membrane 92 (the check valve membrane 92a and the 92b that do not comprise Fig. 5).Film delivery roll 82 guiding of a plurality of positions of process units 80 and send upper thermoplastic film 91a, lower thermoplastic film 91b forward and check valve membrane 92 to the direction H of manufacturing stream shown in Figure 6.
The first step of heat-seal process is by 83 guiding of valve apparatus for heat sealing.Described process is to go up to form check-valves 44 by check valve membrane 92 being attached to upper thermoplastic film 91a.The position of every tunic by up-down rollers controller 84 based on accurately adjusting from the signal of sensor 84 and 89.In described process, check valve membrane 92 is attached on the upper thermoplastic film 91.
Second step of heat-seal process is by main apparatus for heat sealing 85 and belt conveyer 87 guiding.Main apparatus for heat sealing 85 is to be used in conjunction with the thermoplastic film heater, by forming many air chambers that have a lot of air element in conjunction with the border (partition seal) 46 between air chamber and the heat-seal areas 51 (Fig. 2 A-2C).In described heat-seal process, also by be formed for forming the sealing area 72 of venting sheared edge 401 in conjunction with upper strata, lower thermoplastic film and check valve membrane.Typically, main apparatus for heat sealing 85 is the large-scale heaters that form the air-packing device sheet.
Therefore, in the process units of Fig. 6, because belt conveyer 87, the Teflon film moves with the speed identical with 91b with the upper and lower film 91a and can not separate from the upper and lower film 91a and 91b immediately.During this time, when they temporarily pasted on the Teflon film on conveyer belt 87a, the heat sealing part that has high temperature recovered naturally.Thereby at place, belt conveyer 87 ends, the upper and lower film 91a and 91b can be safely from the Teflon film separately.
In described embodiment, cutting machine 201 is set to the part of process units 80, and the thermoplastic film that is used for extending is cut into each unit of air-packing device.Preferably, forming venting sheared edge 401 by the same manner cutting sealing zone 72 shown in Fig. 2 A in the described process.Yet after the sheet of air-packing device was made, making venting sheared edge 401 by the cutting machine that provides respectively in separation process was feasible equally.
The structure of the venting sheared edge 401 that the present invention is above-mentioned has advantage flexibly is set on the size of air-packing device.Fig. 7 A with 7B is and the vertical view of Fig. 2 A to the embodiment of venting sheared edge similar shown in the 2C.What Fig. 7 A showed is the venting sheared edge 401 of air-packing device 40 and the enlarged drawing of check-valves 44.Dotted line 301 shows along the trend of partition seal 69, just along the trend of the calmodulin binding domain CaM between the adjacent air cells.
