Said three sealing mechanisms can respectively seal two sides, top and horizontal line under injection tube while cutting.
Description
The present invention relates to a kind of shaping, filling and water-tight equipment, be used for side by side by a sheet film form one support oneself bag and when carrying sheet film downwards with the compaction material filling should self-support bag.
To form a bag with sheet film be known with the filling and the water-tight equipment of described bag of compaction material filling liquefaction or pasty state simultaneously so far as a kind of for vertical shaping, filling and water-tight equipment.Vertical shaping, filling and water-tight equipment comprise: a sheet film shaping guides is used for sheet film is configured as tubular form; A vertical sealing mechanism is used for the edge of sheet film is sealed into tubular form, to produce the film of tubulose; A pair of compression roller is used for cutting apart the compaction material of introducing film and carries the tubular film that has product separately moving down; An end sealing mechanism is used for by the rotation compression roller and cuts off the not pack portion that the heat-sealing of leak free part along continuous straight runs produces at the film of tubulose.
As a kind of mechanism that can finish heat-sealing at a high speed and can obtain bigger sealing intensity, Japanese Patent Laid-Open Publication the 172403/95th discloses a kind of vertical shaping, filling and water-tight equipment, and it comprises that a heater bar that is used to seal pack portion not and one are used to cool off the cold bar of heat seal lands.Heater bar and cold bar have the ability that can one after the other push down same section when the film feed is in halted state.
The self-support bag that a kind of package-type is arranged on the other hand, now.Because this bag of supporting oneself can be showed with the state display of self-supporting in the shop, so this bag of supporting oneself is widely used for replacing the packaged form of plastic box, bottle, jar recently.
Making self-support bag and filling compaction material in general is to finish in the process of separating.Specifically, prepare a bag in advance, its bottom fold is become the shape of a W, and two sides are sealed, only stay upper opening.Subsequent, at stowing operation, accurately good bag to be taken out one by one, filling is simultaneously along not direction transmission of water.After the filling product is introduced the bag from opening, by sealing the top of tight closing bag.
Yet, carry out the manufacturing and the filling of bag in the process of separating and can not enhance productivity.Therefore, a kind of shaping, filling and water-tight equipment of the bag that is used to support oneself have been developed, can one after the other carry out the manufacturing and the filling of bag, described equipment is folded into half to sheet film, along continuous straight runs transmits folding sheet film, one by one is introducing compaction material behind the cutting bag heat-sealing bottom and two sides from the upper opening of bag, and the top of heat-sealing bag.
Above-mentioned shaping, filling and water-tight equipment have improved the capacity rating of the bag of supporting oneself.But run into new problem again: because film is that along continuous straight runs carries, so the required area of erecting equipment is very big in equipment.
In addition, because compaction material is introduced bag from upper opening, this bag is again that level is carried simultaneously, so also exist dust may enter danger in the bag.Moreover,, be extremely difficult so under the condition of air not being introduced in the bag, seal because the upper opening of bag seals.Therefore, the filling product be easy to oxidation and the situation of rotting under, as food, can not guarantee the quality of product.In addition, under the situation of bubbling easily when compaction material is being introduced in the bag, as cleaning powder, bubble may flow out from the opening of bag in stowing operation, makes the surface contamination of bag, and perhaps bubble adheres to the part that will seal, and causes the seal failure of bag.
Vertical shaping, filling and water-tight equipment are actvies aspect addressing these problems.Yet because the bag of supporting oneself has a very thick bottom, therefore in the process of producing the bag of supporting oneself, how to make this thick bottom by means of vertical shaping, filling and water-tight equipment just becomes key.
In addition, though vertical shaping, filling and the water-tight equipment of disclosed routine be aspect the heat-sealing speed and be advantageous aspect the sealing intensity that produces under the situation of form pillow packs in Japanese Patent Laid-Open Publication the 172403/95th, it is also having the improved place of many needs aspect the bag of supporting oneself producing.Specifically, the bottom of self-support bag needs the heat-sealings of 4 layer films at most.The failure-free heat-sealing of 4 layers part needs to prolong the sealing time, causes the reduction of capacity rating.
An object of the present invention is to provide a kind of shaping, filling and water-tight equipment, manufacturing and the filling of the advantage that is used to utilize conventional shaping, filling and water-tight equipment by realizing bag downwards when film transmits operated to produce effectively and supported oneself bag.

Fix a heater bar holding device 45 between heater bar strut member 43, it is located between two heater bar 44.On the top of each heater bar 44, provide a pressure surface to stretch to heater bar holding device 45.Be pressed on two sides of heater bar holding device 45 at the hoisting force of these pressure surfaces on two heater bar 44 by above-mentioned bont.
Cylinder body 41 is fixed on the framework 10 by means of cylinder body connecting element 42.Cylinder body 41 has a connecting rod of fixing towards heater bar 44.Push rod 47 just passes on this connecting rod that framework 10 is fixed to cylinder body 41.As shown in Figure 5, push rod 47 is positioned at two midways location between the corresponding heater bar axle 46, and by means of the stretching out of connecting rod of cylinder body 41 push rod 47 is pressed to projection 44a, and projection 44a forms on the mutual relative part of each heater bar 44.Therefore, each heater bar 44 is rotated to bear the hoisting force of bont along the direction of leaving mutually, forms a gap whereby between the pressure surface of each heater bar 44 and heater bar 45.
Two bump 1c that formed in film 1 by fold mechanism 30 as shown in Figure 3 pass through between the pressure surface of heater bar 44 and heater bar holding device respectively.When feed stops to release the connecting rod of cylinder body 41, release is by the pressure of the projection on heater bar 44 44 of push rod 47 generations, and each heater bar 44 is all rotated around heater bar axle 46 by means of the hoisting force of their bonts separately, and the pressure surface of each heater bar 44 is pressed on the heater bar holding device 45.Then, by driving the heating arrangement of each heater bar 44, along the top of each bump 1a of vertical heat sealing film 1 of film, as shown in Figure 6.
Return Fig. 1 and 2, the bottom being responsible for 12 provides two pairs of feed rollers 14, is used for keep-uping pressure with the both sides that place film 1 therebetween contacting, and film 1 is sealed by top seal mechanism 20 and bottom sealing mechanism 40.Keep simultaneously contacting with the pressure that places film 1 therebetween by rotating feed roller 14, portability film 1 moves down.
In the bottom of feed roller 14, a pair of compression roller 15 is provided, they and feed roller 14 rotate synchronously.Compression roller 15 is by to placing the contact of exerting pressure of therebetween film 1 to cut apart compaction material 5, and the direction of compression roller 15 arrow A in Fig. 2 can move Face to face.
Bottom at compression roller 15 provides end sealing mechanism 50, is used for along continuous straight runs sealing film 1.
7 end sealing mechanism 50 is described with reference to the accompanying drawings.In Fig. 7, two cylinder bodies 51,56 are provided, their each connecting rod is faced mutually, and film 1 is inserted in the middle of them.Each cylinder body 51,56 all is fixed on each slide block (not shown), and two slide blocks slide along relative horizontal direction.
Cam 52a is provided on the connecting rod of cylinder body 51, on heater bar holding device 54, provides cam to admit roller 54a, thereby when the connecting rod of cylinder body 51 advanced, cam admitted roller 54a just to advance on the cam face of cam 52a.According to this formation, when the connecting rod of cylinder body 51 advances when making cam admit roller 54a to advance on cam 52a, heater bar holding device 54 clockwise directions rotate to resist the hoisting force of above-mentioned spring.
On the connecting rod of another cylinder body 56, the heating arrangement (not shown) of establishing in fixedly having such as the heater bar 57 of electric heater.In addition, provide a cooling rod 58 on cylinder body 56, it is parts that are used to admit cutter grip block 52, can be that rotate in the direction of arrow E at the center with pivot shaft 56.Though cooling rod 58 promotes clockwise direction by a spring (not shown) as previously discussed and rotates, control the position at cooling rod 58 tops, so that the rotation of cooling rod 58 can not surpass the height of the position that is approximately equal to cutter grip block 52.Provide a groove at the top of cooling rod 58, cutter 53 can enter in this groove when the cutter 53 in being clamped in cutter grip block 52 advanced.
Cam 57a is provided on the connecting rod of cylinder body 56, on cooling rod 58, provides cam to admit roller 58a, thereby when the connecting rod of cylinder body 56 advanced, cam admitted roller 58a just to advance on the cam face of cam 57a. Therefore, when the connecting rod of cylinder body 56 advances and cam when admitting roller 58a to advance on cam 57a, cooling rod 58 anticlockwise motions are to resist the hoisting force of above-mentioned spring.
Should illustrate that the electric heater in the end sealing mechanism 50 that present embodiment is represented only is located in the heater bar.Yet, will illustrate as following, because end sealing mechanism 50 will seal 4 layer film shape films (though this is not whole, but this is a special case), its objective is the heat-sealing that will produce a large amount of heat and realize this part reliably, so preferably give also fit on electric heater of heater bar holding device 54.
With reference to the accompanying drawings 2 and accompanying drawing 8a-8c describe the filling and the sealing that realize by means of shaping of the present invention, filling and water-tight equipment and move.
At first, in Fig. 2, when keeping compression roller 15 and end sealing mechanism 50 to open, operate this equipment, inject compaction materials 5, and rotate feed roller 14 simultaneously and move down to carry film 1 from film 1 in-to-in filling tube 11.Owing to top seal mechanism 20 and bottom sealing mechanism 40 are provided above filling tube 11 lower ends, seal by top seal mechanism 20 and bottom sealing mechanism 40 so inject the part of compaction material.
When film be carried one fixing apart from the time, compression roller 15 approaches to cut apart compaction material 5, as shown in Figure 2.
Further downwards the time, shown in Fig. 8 a, in film 1, form the not pack portion 1b that does not have compaction material from above-mentioned state when carry film 1 by means of feed roller 14 and compression roller 15.
When pack portion 1b is not carried between the sealing mechanism 50, stop the feed of film 1 and drive each slide block making it close to move each cylinder body 51,56.At this moment, heater bar 57 has moved forward, and heater bar 57 and heater bar 54 are faced mutually.When each cylinder body is close, shown in Fig. 8 b, heater bar 57 and heater bar 54 are got close to, and push down not pack portion 1b whereby.Then, close mutually heater bar 57 and heater bar holding device 54 seal not pack portion 1b by the heating arrangement that excitation is located in the heater bar 57.
After finishing this heat seal process, shown in Fig. 8 c, this equipment is retracted heater bar 57, and cutter grip block 52 is advanced.By this operation, cooling rod 58 and heater bar 54 all clockwise direction are rotated, and cooling rod 58 moves to the position in cutter grip block 52 the place aheads, and heater bar holding device 54 is recalled downwards simultaneously.As a result, be cooled bar 58 and cutter grip block 52 of pack portion 1b do not pushed down.At this state, the heat seal lands cooling, and cutter 53 is advanced further the part that cut-out has sealed.
Cut off after the part that has sealed, equipment is retracted each cylinder body 51,56, leaves this packing behind.Then, equipment is removed cutter grip block 52, and heater bar holding device 54 is brought back to reference position, and open then compression roller 15 falls down in order to filling next time compaction material.
The self-support bag 1000 that can stand voluntarily exactly of the packing of Huo Deing as shown in Figure 9, makes the part by bottom sealing mechanism 40 (referring to Fig. 1) heat-sealing become the bottom as previously discussed.Because the part by 40 heat-sealings of bottom sealing mechanism plays a strengthening rib, bag 1000 can stably be stood so this is supported oneself, and can not make a mess of bottom 1000a.In addition, because equipment can be finished the shaping and the filling of bag simultaneously, so this equipment can be produced the bag 1000 of supporting oneself efficiently.
In addition, because the shaping of the bag that the present invention finishes makes the part of the bottom 1000a that will become the bag 1000 of supporting oneself be positioned at the side, so the present invention can realize being shaped and filling by carrying film 1 downward process simultaneously.The result, compare with the situation of routine, wherein the injection of compaction material and strict sealing are to finish under along continuous straight runs carries the situation of bag at a unlimited top, and the equipment installing zone of shaping of the present invention, filling and water-tight equipment is less, and dust almost can not enter in the bag.In addition,, compare, can increase the diameter of filling tube 11 with conventional situation by at the implant operation that keeps realizing in the horizontal direction compaction material 5 as the bottom 1000a of the bag 1000 of supporting oneself.As a result, can increase the quantity of the compaction material of unit time injection, therefore, reduce the injection length of compaction material 5, thereby improve the production efficiency of the bag 1000 of supporting oneself.
On the other hand, as previously discussed, the both sides of the bag 1000 of supporting oneself are by end sealing mechanism 50 heat-sealings.Yet the end sealing mechanism 50 of present embodiment is the cutting that realizes heat-sealing and cooling and heat seal lands when the feed of film 1 is in halted state by separately device.Therefore, film 1 is cooling immediately after heating finishes, and therefore can carry out heating, cooling and the cutting process of film 1 effectively, can realize whereby from being heat sealed to the high speed operation of cutting process, and thereby improved heat seal strength, and can reduce sealed width.
Specifically, by the film 1 in the part of end sealing mechanism 50 heat-sealing be with the cooresponding part of bump 1c shown in Figure 3 four times.When the bag 1000 of supporting oneself during, place this heat seal lands of four times so that can show them two sides as commodity display.Therefore, require end sealing mechanism 50 can finish certain heat-sealing of the film that quadruples.Also have, do not stay the gap in order to display commodity effectively side by side, the sealed width of both sides is preferably narrow as much as possible.Therefore, the end sealing mechanism 50 that provides big sealing intensity and narrow sealed width of present embodiment is suitable for use as heat sealing mechanism of the present invention.
In addition, because end sealing mechanism 50 is applied to the heat-sealing of the not pack portion 1b that is formed by compression roller 15, so can prevent air admission self-support bag 1000.As a result, in the packing of food, can prevent the Food Oxidation packed or rot.
Now, as previously discussed, feed roller 14 ground carry film 1.In general-duty shaping, filling and water-tight equipment, use the film on the film supply roll (not shown).Therefore, advance, exist some worry of the unstable feed that produces for inertia by film supply roll when film supply roll batch (-type) ground changes.Unstable feed will cause the film bending.
The mechanism that rotates film supply roll when batch (-type) ground rotates film feed roller 14 continuously prevents that the film bending is necessary.Therefore, the shaping of present embodiment, filling and water-tight equipment have a stretching device 60 as shown in figure 35, and it is between film supply roll and idler roller 14 (see figure 1)s.
Stretching device 60 comprises a swing arm 61 that rotates around horizontal shaft 61a.In the side of swing arm 61, provide two roller 67a, 67b.In addition, above roller 67a, 67b, arrange two other roller 65a, 65b.
Pull down moving swing arm 61 by tension spring 68.Arrange the motion of stops 64 in the above and below of swing arm 61 with restriction swing arm 61.
In addition, stretching device 60 also comprises a pair of feed help roll 66a, 66b and a jockey pulley 69, and jockey pulley 69 is arranged between feed help roll 66a, 66b and the film feed roller.
Below, the service condition of this stretching device 60 is described.
Before shaping, filling and water-tight equipment were started working, swing arm 61 was in nethermost position under the effect of the power of tension spring 68.At this state,, and stop feed help roll 66a, 66b with the afterbody 62 of sensor 63 wobble detection bars 61.
When rotating feed roller 14 (see figure 1)s, provide film 1 along the direction of arrow J.By means of this feed of film, mention swing arm 61 along the direction of arrow K, and afterbody 62 leaves sensor 63.When afterbody 62 left sensor 63, feed help roll 66a, 66b rotated.By the rotation of feed help roll 66,66, film 1 is pulled out from the film feed roller.
After this, according to batch (-type) ground film feed mode, swing arm 61 does not move up and down in sensor 63 does not detect a scope of afterbody 62.Therefore, owing to eliminated film 1 becoming flexible between feed help roll 66,66 and idler roller 16 (see figure 1)s by the mobile of swing arm 61, so might when feed roller 14 batch (-type) ground rotate, provide film 1 continuously from film supply roll.
Above-mentioned operation can prevent that excessive masterpiece is used on the film, can prevent that film from bending between film supply roll and feed roller.Therefore, realized stable film feed by stretching device 60.
If the film feed is owing to reasons such as for example breakdown of equipment stop for a long time, swing arm 61 moves down and by sensor afterbody 62.When detecting afterbody 62, feed help roll 66a, 66b stop.As a result, stopped film supply from film supply roll.
And then, as previously discussed, in the heat seal lands of two sides of the bag 1000 of supporting oneself, be four layers or more multi-layered part than the more difficult heat-sealing of other parts corresponding to film 1 part of bump 1c shown in Figure 3.Specifically, the stress concentration that the top of the inside folded portions of film 1 (the part F in Fig. 9 a) causes easily owing to the impact from for example decline when internal pressure is added to the bottom of the bag 1000 of supporting oneself, and because part F is positioned on the portion boundary of four-level membrane partial sum double-layer films 1, what be concerned about is exactly that heat-sealing may be thrown off at part F.
Therefore, peel off, preferably use bottom sealing mechanism shown in Figure 10 in order to prevent heat seal lands.The top of the heater bar 84 of bottom sealing mechanism shown in Figure 10 provides a plurality of flange 84b, is used for local heat-sealing.The flange 84b that is used for local heat-sealing is arranged on the more cooresponding positions, two sides (with reference to Fig. 9) with the corner of bottom and the self-support bag 1000 that produced.Be located at the number of the flange 84b that is used for local heat-sealing on the heater bar 84, for example when the vertical length of heater bar 84 be 2 when being the corresponding length of bag length with the bag 1000 of supporting oneself, when the relative length of heater bar 84 is 4 during corresponding to its two bag lengths.
In addition, in heater bar holding device 85, provide a plurality of boss 85b that admit the flange 84b that is used for local heat-sealing equably.By closed each heater bar, the top that is used in the flange 84b of local heat-sealing is pressed in the side of boss 85b respectively, thus a local part that has sealed two bump 1c shown in Figure 3.
Because other component part is similar to the various piece of the bottom sealing mechanism shown in Fig. 4 a, the 4b, 5, so save the detailed description to them.
As shown in figure 11, by using bottom sealing mechanism as shown in figure 10,4 positions bottom the side of bag 1000 of supporting oneself form partially sealed point 1002 (only showing two points in Figure 11).By means of these partially sealed points 1002, just can save near the prolongation of the bump in bag 1000 sides of supporting oneself.Therefore, big internal pressure becomes and almost can not partly produce at F, thereby can keep the heat-sealing of this part to be in the stabilized conditions that almost can not throw off.

Bottom at film shaped guides 111 is provided with a fold mechanism 130, is used for further being folded in the centre portion in the zone between two edge 101a that film 191 forms by film shaped guides 111.The similar of fold mechanism 130 is in the fold mechanism that illustrated in first embodiment, and the film 101 by fold mechanism 130 is folded into as shown in figure 15 W form, thereby forms two bump 101b.
In fold mechanism 130 bottoms, bottom sealing mechanism 140 is set, be used for two bump 101b that form by fold mechanism 130 along the longitudinal sealing of film 101.In addition, the position of passing filling tube 14 on the opposite of bottom sealing mechanism 140 is provided with top seal mechanism 120, is used to seal the surface by the coupling of preparing along the open end of the overlapping film 101 of lateral edge.By the lateral edge portions of heat sealing film 101, film 101 is processed into tubular form.
With further reference to accompanying drawing 12 and 13, well-known is that the bottom in bottom sealing mechanism 140 and top seal mechanism 120 provides two pairs of feed rollers 116, is used for two sides of pressure maintenance by the film 101 of above-mentioned sealing mechanism heat-sealing.It is downward to carry film 101 by rotation feed roller 116, simultaneously extrusion film 101 between feed roller 116.
Below feed roller 116, a pair of compression roller 117 is provided, compression roller 117 is oppositely arranged mutually, and simultaneously film 101 is clipped between the compression roller, and compression roller 117 and feed roller 116 rotate synchronously.Compression roller 117 is by being used to cut apart the compaction material (representing with oblique line) that injects film 101 from both sides extrusion film 101, the purpose that compression roller 117 is provided is that it can be moved in the direction of arrow A by the driving of actuating device (not shown).Compression roller 117 by from both sides extrusion film 101 and rotate and with feed roller 116 concerted actions, it is downward to carry film 101.Should illustrate, above the compression roller 117 and bottom sealing mechanism 140 below the bottom of filling tube 114 is set.According to this structure,,, and can realize good sealing so bottom sealing mechanism 140 can keep not having compaction material because compaction material is injected into the space of bottom sealing mechanism 140 bottoms.
In the bottom of compression roller 117, end sealing mechanism 150 is provided, be used for having comprised the film 101 of compaction material along horizontal (along continuous straight runs) heat-sealing.
Below, with reference to accompanying drawing 16-18 end sealing mechanism 150 is described.
As shown in figure 16, end sealing mechanism 150 is made up of two unit 1501,1551.Unit 1501,1551 is oppositely arranged mutually, and the path of passing through of a film 101 is arranged in their centre.Each unit 1501,1551 all is an individual drive, is used for heat-sealing and cutting film 101.
Shown in Figure 16-18, first module 1501 comprises first sealing mechanism 1510 and first cooling body 1520, and the both vertically is supported on two vertically extending axis of guides 1502 slidably.
As shown in figure 17, first sealing mechanism 1510 comprises the support frame 1511 that is supported by the axis of guide 1502, with the primary heater bar 1514 and the primary heater bar holding device 1515 that are located on this support frame 1511, they can be respectively is that rotate at the center with pivot shaft 1512,1513 on horizontal surface.Primary heater bar 1514 has the heating arrangement (not shown) of establishing in, as electric heater.Primary heater bar 1514 is by coupling element 1518 and driving cylinder body 1516 couplings that are located on the support frame 1511.By stretching out the connecting rod that drives cylinder body 1516, primary heater bar 1514 is rotated along the direction of the arrow G shown in Figure 17.Primary heater bar holding device 1515 is by coupling element 1519 and driving cylinder body 1517 couplings that are located on the support frame 1511.By stretching out the connecting rod that drives cylinder body 1517, primary heater bar holding device 1515 is rotated along the direction of the arrow H shown in Figure 17.
Therefore, when the connecting rod of two driving cylinder bodies 1516,1517 all stretched out simultaneously, heater bar 1514 and heater bar holding device 1515 were pushed down film 101 to approaching together.On the contrary, when the connecting rod of two driving cylinder bodies 1516,1517 was all removed simultaneously, heater bar 1514 and heater bar holding device 1515 were opened together, discharge film 101.
Bottom at first sealing mechanism 1510 is provided with first cooling body 1520.As shown in figure 18, first cooling body 1520 comprises the support frame 1521 that is supported by the axis of guide 1502, with first cooling rod 1524 and the first cooling rod holding device 1525 that are located on this support frame 1521, they can be respectively is that rotate at the center with pivot shaft 1522,1523 on horizontal surface.First cooling rod 1524 is by coupling element 1528 and driving cylinder body 1526 couplings that are located on the support frame 1521.By stretching out the connecting rod that drives cylinder body 1526, first cooling rod 1524 is rotated along the direction of the arrow G shown in Figure 18, identical with the operating mode of primary heater bar 1514.The first cooling rod holding device 1525 is by coupling element 1529 and driving cylinder body 1527 couplings that are located on the support frame 1521.By stretching out the connecting rod that drives cylinder body 1527, the first cold heater bar holding device 1525 is rotated along the direction of the arrow H shown in Figure 18, identical with the operating mode of primary heater bar holding device 1515.
Therefore, when the connecting rod of two driving cylinder bodies 1526,1527 all stretched out simultaneously, cooling rod 1524 and cooling rod holding device 1525 were pushed down film 101 to approaching together.On the contrary, when the connecting rod of two driving cylinder bodies 1526,1527 was all removed simultaneously, cooling rod 1524 and cooling rod holding device 1525 were opened together, discharge film 101.
On the other hand, the ball nut 1507 that extends in vertical direction is connected with the rotating shaft of cooling body actuating device 1504.In order to pass through cooling body drive motor 1504 vertical drive first cooling body 1520, ball bolt 1507 is screwed on the ball nut 1508 that is fixed on the support frame 1521, and is passed on the hole 1511a that forms on the support frame 1511.Therefore, by driving cooling body drive motor 1504 rotation ball bolts 1507, just the rotational motion of ball bolt 1507 is converted to the perpendicular movement of first cooling body 1520 again through ball nut 1508.
In other words, first sealing mechanism 1510 and first cooling body 1520 vertical shifting independently of each other.
The structure of the cooling rod 1524 and the cooling rod holding device 1525 of first cooling body 1520 is described with reference to accompanying drawing 19 here.As shown in figure 19, the cutter 1530 of horizontal resection film 101 is clamped in the cooling rod holding device 1525, can be flexible to cooling rod 1524 by the cylinder that does not show.On the other hand, form a groove 1524a in cooling rod 1524, when cutter 1530 advanced, cutter 1530 can enter among the groove 1524a.On the surface of the cooling rod holding device 1525 on the opposite on the corresponding surface of cooling rod 1524, bonding silicone rubber 1525a.
Now, cutter 1530 keeps being retracted in the cooling rod holding device 1525 in the ordinary course of things.Yet, closed and at cooling rod 1524 and cooling rod holding device 1525 through a preset time after the cycle (below discuss again), cutter 1530 stretches out from cooling rod holding device 1525, and its top is entered among the groove 1524a of cooling rod 1524, cuts off film 101.
The effect of first cooling body 1520 is by first heat sealing mechanism 1510 and through the contact of the pressure between cooling rod 1514 and the cooling rod holding device 1525, cools off the heat seal lands of film 101 effectively.First cooling body 1520 by the good material of heat conduction for example aluminium constitute.In addition,, can use cooling media, for example liquid or gas, the inside that is used to cool off cooling rod 1524 in order to improve cooling performance.
Below described the first module 1501 of end sealing mechanism 150, but second unit 1551 also have the formation identical with first module.In other words, as shown in figure 16, second unit 1551 has second sealing mechanism 1560 and second cooling body 1570, and the both vertically is supported on slidably on two axis of guides 1552 and (only expresses one of them).Second sealing mechanism 1560 has secondary heater bar 1564 and secondary heater bar holding device 1565, and they can back and forth rotate to exert pressure on horizontal surface respectively under the driving that drives cylinder body.Second cooling body 1570 has second cooling rod 1574 (with reference to accompanying drawing 20a) and the second cooling rod holding device 1575, and they can drive under the driving of cylinder body and relatively rotate on horizontal surface to exert pressure respectively.The similar of secondary heater bar 1564, secondary heater bar holding device 1565, second cooling rod 1574 and the second cooling rod holding device 1575 is in the structure of primary heater bar 1514, primary heater bar holding device 1515, first cooling rod 1524 and the first cooling rod holding device 1525, so economize the description of having moved for the former here.Adopt in a like fashion with first module, can realize the vertical shifting of second sealing mechanism 1560 and second cooling body 1570 by two cooresponding ball bolt arrangements independently of each other.
Because the first module 1501 and second unit 1551 relatively are provided with as mentioned above, so when primary heater bar 1514 and primary heater bar holding device 1515 close up, can move to second sealing mechanism 1560 from the top of first sealing mechanism 1510 below of first sealing mechanism 1510; Perhaps when being in separately state, secondary heater bar 1564 and secondary heater bar holding device 1565 move to the top of first sealing mechanism 1560 from the below of first sealing mechanism 1560.Vice versa: when secondary heater bar 1564 and secondary heater bar holding device 1565 close up, can move to first sealing mechanism 1510 from the top of second sealing mechanism 1560 below of second sealing mechanism 1560; Perhaps when being in separately state, primary heater bar 1514 and primary heater bar holding device 1515 move to the top of second sealing mechanism 1560 from the below of second sealing mechanism 1560.
About first cooling body 1520 and second cooling body 1570, its serviceability may be similar to the above, so by when first cooling rod 1524 and the first cooling rod holding device 1525 close up, opening second cooling rod 1574 and the second cooling rod holding device 1575 or, just can randomly improving sealing mechanism and concern in the position of vertical direction by closed second cooling rod 1574 and the second cooling rod holding device 1575 when first cooling rod 1524 and the first cooling rod holding device 1525 are opened.
Below, will the filling-packaging operation of shaping, filling and the water-tight equipment of present embodiment be described.
At first, in Figure 12 and 13, when keeping compression roller 117 to separate, from filling tube 114 compaction material is injected into film 101, it is downward to carry film 101 to rotate feed roller 116 simultaneously.At this moment, in film 101, produced two bump 1c (with reference to accompanying drawing 15), and then sealed the part that the film 101 of compaction material wherein is provided by top seal mechanism 120 and bottom sealing mechanism 140 by fold mechanism 130.
When carry 101 1 of films apart from the time, compression roller 117 closes up to separate compaction material.At this state, when further rotating, feed roller 116 and compression roller 117 carry film 101 downwards the time, in film 101, form the not pack portion 101d that does not comprise any compaction material.By cutting off this not pack portion 101d, can produce the self-support bag 1000 (with reference to accompanying drawing 9) of the compaction material that comprises strict seal with end sealing mechanism 150.Operation at end sealing mechanism 150 manufacturing self-support bags is described with reference to Figure 20 a-20k below.
In Figure 20 a-20k,, in the mechanism relevant, add oblique netting twine with second unit 1551 for making explanation clear.In addition, each operation of 0.1 second is represented in each action of representing in Figure 20 a-20k.
Shown in Figure 20 a state, second sealing mechanism 1560 is in the extreme higher position, first sealing mechanism 1510 is positioned at the below of second sealing mechanism 1560, the two spacing that separates equals the width of the self-support bag that will make.Also have, first cooling body 1520 is positioned at the below of first sealing mechanism 1510 and separates identical spacing, and second cooling body 1570 is positioned between first sealing mechanism 1510 and first cooling body 1520.At this moment, primary heater bar 1514 and primary heater bar holding device 1515 close up with heat sealing film 101.In addition, first cooling rod 1524 and the first cooling rod holding device 1525 also close up to keep the bottom of film 1 at first sealing mechanism 1510.
Here, should illustrate that the part of the film 101 that is kept by first cooling rod 1524 and the first cooling rod holding device 1525 is exactly one before a series of circulations of being represented by a Figure 20 a-20k part that circulates in previous action by 1560 heat-sealings of second sealing mechanism.
In this way, when keeping film 101 by first sealing mechanism, 1510 heat sealing films 101 and by first cooling body 1520, the downward feed film 101 of end sealing mechanism, and and the film feeding speed synchronously moves down first sealing mechanism 1510 and first cooling body 1520, when the P shown in the perpendicular separation between second sealing mechanism 1560 and first sealing mechanism 1510 reaches shown in Figure 20 a, stop the feed of film 101, and stop to move down of first sealing mechanism 1510 and first cooling body 1520 simultaneously.
Subsequent, shown in Figure 20 b, secondary heater bar 1564 and secondary heater bar holding device 1565 close up, the not pack portion 101d of beginning heat sealing film 101.When secondary heater bar 1564 and secondary heater bar holding device 1565 close up, shown in Figure 20 c, primary heater bar 1514 and primary heater bar holding device 1515 are opened, and shown in Figure 20 d, first sealing mechanism 1510 and second cooling body 1570 raise immediately then.Also have in this point, compression roller 117 is opened, and the compaction material by compression roller 117 clampings is dropped to the position of second sealing mechanism, 1520 tops.
When the position of second cooling body 1570 becomes and during by the heat seal lands 105 same height of the side of the film 101 of first sealing mechanism 1510 heat-sealing, shown in Figure 20 e, second cooling rod 1574 and the second cooling rod holding device 1575 of second cooling body 1570 close up, thereby begin being cooled off by the side seals part 105 of first sealing mechanism, 1510 heat-sealings.On the other hand, below second cooling body 1570, the cutter 530 of first cooling body 1520 (with reference to accompanying drawing 19) stretches out, and cuts off the part by this action heat-sealing before the circulation.
With reference to as described in the accompanying drawing 20a-20e, when the position of first sealing mechanism 1510 and second cooling body 1570 changes the part that has sealed with cooling, stop the feed of film 101 as above.Therefore, controlling for the position of the part of the film 101 that will be pushed down by second cooling body 1570 is easily, and therefore second cooling body 1570 can be pushed down the part of having been pushed down by first sealing mechanism 1510, thereby can finish certain cooling down operation to this part exactly.
When film 101 was cut off by first cooling body 1520, shown in Figure 20 f, first cooling rod 1524 and the first cooling rod holding device 1525 of first cooling body 1520 were opened, the self-support bag 1000 that landing obtains.At this moment, compression roller 117 closes up with the cutting compaction material, impels first sealing mechanism 1510 to rise simultaneously.
Next, shown in Figure 20 g-20k, it is downward to carry film 101 by the compression roller 117 of closure, and second sealing mechanism 1560 and second cooling body 1570 synchronously descended with the film entrainment velocity.During this period, finish the seal operation of second sealing mechanism 1560 and the cooling down operation of second cooling body 1570 continuously.In addition, with also having that the above is finished, first sealing mechanism 1510 and first cooling body 1520 raise.When the state that becomes shown in Figure 20 h, promptly, first sealing mechanism 1510 wherein and the position of second sealing mechanism 1560, and the position of first cooling body 1520 and second cooling body 1570 compares the state of all exchanging with Figure 20 a, stops the feed of film 101.
After this, replace the action of first sealing mechanism 1510 by action with second sealing mechanism 1560, replace the action of first cooling body 1520 with the action of second cooling body 1570, and repeat above process, just can produce the bag 1000 of supporting oneself one by one.As previously discussed, each process of representing of Figure 20 a-20k is represented a stage of 0.1 second.Therefore, in the present embodiment, produced each bag 1000 of supporting oneself as a circulation with per 1 second.
On the other hand, heat-seal operation in the bag both sides of supporting oneself is finished by use end sealing mechanism 150 as previously discussed, end sealing mechanism 150 has 1510,1560 and two cooling bodies 1520,1570 of two sealing mechanisms, in other words, when carrying film 101 downwards the time, heat-seal operation by alternately use sealing mechanism 1510 and 1560, then by alternately using cooling body 1520,1570 to finish.Yet when carrying film 101, the cooling of the heat-sealing of film 101 and the heat seal lands finished by above-mentioned action is carried out simultaneously, and will carry out-of-run heat sealing mechanism in addition and the cooling body that do not cool off is upwards manipulated for the next one.
By means of above-mentioned process, might after finishing, current heat-seal operation begin next heat-seal operation immediately, perhaps before finishing, current heat-seal operation just begins next heat-seal operation, and therewith together, can after finishing, current heat-seal operation begin the cooling of this heat seal lands immediately.Therefore, use this system, might produce at high speed and filling self-support bag 1000, can guarantee again to be used for certain heat-sealing of film 101 and to cool off the necessary time simultaneously, but can not reduce production efficiency.In addition, owing to after heat-sealing finishes, cool off film 101 immediately, so can realize sealing, cooling off and cut each process of film 101 effectively, and can improve, can increase heat seal strength simultaneously from the operating speed of all processes that are heat sealed to cutting itself.
As previously discussed, because heat-sealing is finished by means of heat sealing mechanism 1510,1560, while and film 101 have moved down heat sealing mechanism 1510,1560 together, so generally all use this shifting time as the heat-sealing time.Here, in the present embodiment, when cooling off the part that has sealed, stop the feed of film for the part that has sealed is carried out certain cooling.Replace sealing mechanism 1510,1560 and cooling body 1520,1570 then respectively, yet, before replacing sealing mechanism 1510,1560 and cooling body 1520,1570, to begin heat-sealing with another sealing mechanism.Therefore, except the time of carrying film 101, can use film feed standing time as the heat-sealing time.
In addition, the situation of cooling down operation is similar.The end sealing mechanism 150 of present embodiment comprises two groups of cooling bodies 1520,1570.And the feed standing time that can use feed time of film 101 and film 101 is as the hardening time of being finished by cooling body 1520,1570.
For example, under the situation of the bag 1000 of supporting oneself as one of per second manufacturing in the present embodiment, can use the time of being longer than a cycle time (1 second) slightly in practice.Specifically, can use the time that is about conduct heat-sealings in 1.2 seconds.
As a result, owing to all distributed the sufficiently long time for the heat-sealing time of sealing mechanism 1510,1560 and the hardening time of cooling body 1520,1570, can realize failure-free heat-sealing more.Specifically, at the bag 1000 of supporting oneself as manufacturing in the present embodiment, owing to need the lap of heat sealing film 1, mostly be most 4 layer films 1, so can think, above-mentioned end sealing mechanism 150 is the end sealing mechanisms that are suitable for being used in shaping, filling and the water-tight equipment that can make the bag 1000 of supporting oneself.
Shown in Figure 20 b-20e, in order to cool off heat seal lands, for example when replacing first sealing mechanism 1510, by means of second sealing mechanism 1560 and first cooling body 1520 film 1 is supported on top or bottom by first sealing mechanism, 1510 leak free side seals parts 105 respectively with second cooling body 1570.Therefore, second cooling body 1570 can be pushed down exactly by the side seals part 105 of first hermetic unit, 1510 heat-sealings and can not depart from from this part.
In the self-support bag of making by shaping, filling and the water-tight equipment of present embodiment 1000, shown in Figure 20 a-20k, also there is the compaction material of two bags of amounts or three bags of amounts in the bottom of compression roller 117.Also have, as shown in figure 21, film 101 is before cutting, will by the side of the bottom hermetic unit 104 of bottom sealing mechanism 140 (with reference to accompanying drawing 12) heat-sealing with to compare by top seal mechanism 120 (with reference to accompanying drawing 12) leak free top seal part 103, expand some, under state of nature, demonstrated bending.
Therefore, side seals part 105 is not parallel to each other, if therefore fixing by the upper and lower of the part of first sealing mechanism, 1510 heat-sealings, side seals part 105 just might take place a bit mobile when first sealing mechanism 1510 leaves film 101.In other words, be subjected to the influence of the position deviation of film 101 itself, sometimes mistake will take place, promptly second cooling body 1570 can not be pushed down side seals part 105 exactly.Under such a case, second sealing mechanism 1570 can be breaking at the side seals part 105 under this state.If second sealing mechanism, 1570 cut-off parts in the worst case, may cut off the part except that side seals part 105 at the film of deviation position, compaction material will leak.
Therefore, as in the present embodiment, when sealing mechanism 1510,1560, cooling body 1520,1570 are all correspondingly reverse, preferably keep their upper and lower motionless, depart to prevent off-position.
In addition, in the present embodiment, the operation of finishing is opened compression roller 117, keeps heat sealing mechanism 1510,1560 to be in simultaneously and closes up state; Compaction material falls into the space of heat sealing mechanism 1510,1560 tops; The film 101 that is carried under this state is downward; Compression roller 117 closes up, so that form not pack portion 101d in film 101; Then, seal this not pack portion by means of in the heat sealing mechanism 1560,1510 another.According to this process, from cutting apart compaction material in the time of the not pack portion 101d of heat sealing film 101, film 101 is always only admitted the compaction material of a bag weight.As a result, owing to do not have extra weight will be added in the film 101, so can obtain the good self-support bag 1000 of tension state.
By the way, the self-support bag of producing 1000 is that one unit is packaged in the case so that transport with several or tens bags.Yet, as shown in Figure 9,, can oneself stand whereby because the bag 1000 of supporting oneself has a projection at bottom 1000a, it is very difficult arranging these bags in a bag abreast.
In order to arrange the bag 1000 of supporting oneself easily, be preferably in and use cutter 1521 in each cooling body 1520 and 1570, as shown in figure 22.
Have the concave surface 1532 of a plurality of 2-3 mm wides at the cutter shown in Figure 22 1531 in a side, form blade 1531a in the side (inside that comprises it) of concave surface 1532.In order to use this structure cuts film, cutter 1531 will stretch out a distance C 1, blade 1531a in concave surface 1532 still separates this distance C 1 with film, the film of cutting only is the part except that concave surface 1532, and when cutter further stretches out a distance C 2, this can cut the blade 1531a of concave surface 1532, thereby can cut off film fully.
If in first cooling body 1520 and second cooling body 1570 each all provides such cutter 1531, cut film by outreach C1 in the ordinary course of things, and every 5 such cuttings, arranging outreach is the film cutting of C2.Then, as shown in figure 23, obtain the series package 1200 of 5 bags, comprising 5 bags 1100 of supporting oneself, they connect side by side by junction surface 1100.By connecting the series package that the bag 1100 of supporting oneself makes it to become 5 bags in this way, just can save the time of in case, arranging self-support bag 1100 one by one, simplified packaging operation whereby.
On the other hand, when such self-supports of display bag in the shop 1100, can cut off each bag 1100 of supporting oneself at each 1110 place, bonding part so that display.The width at junction surface 1110 is corresponding to the width of the concave surface 1532 of cutter 1531, and as previously discussed, because the width of concave surface 1532 is 2-3 millimeters, so the cutting at junction surface 1110 is easily.Here, though for example series package 1200 of 5 bags has been described, wherein each bag 1100 of supporting oneself is by two junction surface 1110 bonded assemblys, but the number of the number at junction surface 1110 and the bag 1100 of supporting oneself all can randomly be determined according to the size of the material of used film, the bag 1100 of supporting oneself and the size of packing chest.
The 3rd embodiment
Above-mentioned first and second embodiment have expressed shaping, filling and water-tight equipment, are used for making the bag of supporting oneself effectively according to the operating principle of vertical shaping, filling and water-tight equipment, can not introduce any external substance.
From the above embodiments obviously as can be seen, the bag of supporting oneself has a thick end, and the degrees of expansion of bag is different with the position.Therefore, when heat sealing film, compare, in film, trend towards producing fold with the packing of making pincushion.When producing this fold, it has not only damaged the outward appearance of packing, and has damaged good sealing property, and relevant with situation, and compaction material might leak from this part.
Therefore, fold do not occur for making film, present embodiment provides a filling and packing equipment, and this filling and packing equipment can be realized heat-sealing preferably, can also utilize the advantage of vertical filling packaging facilities simultaneously.
According to shaping of the present invention, filling and water-tight equipment manufacturing self-support bag 2000 as shown in figure 34, this self-support bag 2000 has top seal part 2001, side seals part 2002 and bottom hermetic unit 2003.The general configuration of shaping of the present invention, filling and water-tight equipment at first, is described with reference to accompanying drawing 24,25.
Near the top of filling tube 211, a film shaped fold mechanism 220 is provided, be used for the folding film of supplying with from the film supply roll (not shown) by means of guiding roller 212 101, make two sides overlap and in the part of folded inside as the bottom of the bag 2000 of supporting oneself.
In the bottom of a film shaped fold mechanism 220, bottom sealing mechanism 230 and top seal mechanism 240 are provided, be used for vertical heat sealing film 101 along film, by film shaped fold mechanism 220 film 101 is folded into fixed shape.Bottom sealing mechanism 230 is provided with in relative position with top seal mechanism 240, and filling tube 211 is in their centre.Bottom sealing mechanism 230 forms the bottom hermetic unit 2003 (with reference to accompanying drawing 34) of the bag 2000 of supporting oneself, and top seal mechanism 240 forms the top seal part 2001 (with reference to accompanying drawing 34) of the bag 2000 of supporting oneself.
Below bottom sealing mechanism 230, enhanced leaktightness mechanism 250 is provided, be used for strengthening a part by the part of bottom sealing mechanism 230 heat-sealings; And, more down, provide two pairs of feed rollers 213, it is downward to be used to carry film 101.In the bottom of feed roller 213, a pair of compression roller 214 is provided, the rotational synchronization ground of they and feed roller 213 rotates.Feed roller 213 is all similar with first embodiment and first embodiment with compression roller 214.
Should illustrate that the bottom of filling tube 211 is positioned at the top of compression roller 214 and the below of enhanced leaktightness mechanism 250.Therefore, because the position below enhanced leaktightness mechanism 250 provides the compaction material by filling tube 211 inputs, so can keep enhanced leaktightness mechanism 250 not have compaction material, therefore, enhanced leaktightness mechanism 250 can finish heat-seal operation satisfactorily.
Below compression roller 214, end sealing mechanism 260 is set, be used for providing the film 201 of compaction material along horizontal (along continuous straight runs) heat-sealing, form the side seals part 2002 (with reference to accompanying drawing 34) of the bag 2000 of supporting oneself.
Below, film shaped fold mechanism 220, bottom sealing mechanism 230, top seal mechanism 240 and the enhanced leaktightness mechanism 50 described more than describing in detail.Should illustrate that end sealing mechanism 260 has and the end sealing mechanism 50 shown in first embodiment (with reference to accompanying drawing 7) identical mechanism, has saved the detailed description to it here.
26 film shaped fold mechanism 220 is described with reference to the accompanying drawings.
As shown in figure 26, arrange a trapezoidal plate 221 obliquely with respect to vertical direction below guiding roller 212, the top margin of trapezoidal plate 221 is greater than the base but less than the width of film 101, and its two hypotenuses have identical angle.Near the base of trapezoidal plate 221, a rectangular width adjustment plates 223 vertically is set, the width of width adjustment plates 223 equals the length of the bottom side of trapezoidal plate 221.In the both sides of width adjustment plates 223, two guide arms 222 are provided, extend perpendicular to the direction of the Width of width adjustment plates 223 on their along continuous straight runs and edge.
By driving feed roller 213 (with reference to accompanying drawing 24 and 25), and feed roller 213 contacts with the top surface of trapezoidal plate 221 and the intimate of width adjustment plates 223, the film 101 that can carry by guiding roller 212 moves down, and by the extension of each guide arm 222 from the end of the outside limits film 101 of film 101.By this process, in film 101, form two edge 101a, as shown in figure 14, thereby make film 101 be configured as skewed slot shape.Zone between these edges 101a has just become the lower surface of the bag of supporting oneself.
Below width adjustment plates 223, a push pedal 225 and two baffle plates 224 are set, be used for further inwardly being folded in the zone between two edge 101a that film 101 forms.Push pedal 225 is parts of a del, and push pedal 225 is set obliquely, so that can push as shown in figure 14 the zone between two edge 101a of film 101 to it from the outside of film 101.The purpose that each baffle plate 224 is provided is two the edge 101a of inside clamping from film 101, so that control, makes can not promote each edge 101a when pushing film 101 by baffle plate 225.In the inside of film 101 each baffle plate 224 is set relatively, and they are spaced from each other.By means of this structure, make it to become the shape of letter w at the folding film 101 (as shown in figure 15) that passes push pedal 225 and each baffle plate 224 of that side relative, and finally form two bump 101b and a recessed portion between two bump 101b with opening end.
Between two baffle plates at the top of baffle plate 224 space is arranged, its size equals the width of regulating plate 223, and is tilted to down placement respectively, and their space each other reduces gradually, and is corresponding with the inclination of the hypotenuse of push pedal 225.Carry the film 101 that passes push pedal 225 and each baffle plate 224 and move down, its both sides are by pressure roller 226 clampings.
As previously discussed, the film 101 by trapezoidal plate 221 surfaces is by two hypotenuses and the base bending of trapezoidal plate 221, and band downwards.At this moment, because two hypotenuses become angle same with respect to the line of centers of trapezoidal plate 221, so the position of film 101 is self-regulating, thereby it is equal that the load that is added on each hypotenuse is become, thereby can prevent the positional error of film 101 at Width.In addition, when forming the bump that has become bottom hermetic unit 2003 (with reference to accompanying drawing 34), because edge 101a (it is the top of bump 101b) forms by means of trapezoidal plate 221 and width adjustment plates 223, so the position of each bump 101b will never be departed from.In other words, the position of two bumps overlaps, and the distance of broad ways is also consistent with each other between the end of each bump 101b and film 101.
Owing to stably carry film 101 and bending can not occur, and two bump 101b form reliably in fixing position, so might stablize the heat-sealing position of top seal mechanism 240 and bottom sealing mechanism 230.Moreover, owing to prevented generation in the position deviation of the Width of film 101, so, can in film 101, not produce fold even push by compression roller 214 yet.So, might realize the good heat-sealing that realizes by end sealing mechanism 260.
Also have, owing in film 101, inwardly fold the centre portion of each edge 101a behind two edge 101a of formation by means of width adjustment plates 223, so can shorten the length that makes it to become the film 101 of the required feed of part as shown in figure 15 for folding film 101, and can be controlled at the height of shaping, filling and water-tight equipment the size of this length.
Referring now to accompanying drawing 27 and 28 bottom sealing mechanism 230 is described.
As shown in figure 27, bottom sealing mechanism 230 is fixed on the framework 210a of shaping, filling and water-tight equipment, and comprises: two cylinder bodies 233, and cylinder body 233 is fixed on the framework 210a, has the connecting rod 233a that is oppositely arranged mutually; Two bottom seal bar 231, each bottom seal bar 231 is all supported by the strut member on the connecting rod 233a that is fixed to each cylinder body 233 232, and the pressure surface of bottom seal bar 231 relatively is provided with mutually; With, by the admittance plate 234 that framework 210a supports, its top is inserted between each bottom seal bar 231.Arrange for the distance between each bottom seal bar 231 and the admittance plate 234, so that make admittance plate 234 can push down bottom seal bar 231 by the connecting rod 233a of the cylinder body 233 that protracts.
Be inserted in two states between the bump 101b at admittance plate 234 and carry the film 101 that folds by above-mentioned film shaped fold mechanism 220.Each bottom seal bar 231 has the temperature booster (not shown) of establishing in, as electric heater.By with this heater heats each the bottom seal bar 231, and drive simultaneously each cylinder body 233 make each the bottom seal bar 231 advance, just sealed at the same time and be clamped in the part of admitting the film 101 between plate 234 and the bottom seal bar 231, i.e. two bump 101b.
Here, the pressure surface of each bottom seal bar 231 all has a protruding 231a in dash area formation as shown in figure 28, it is than higher on every side, and when the pressure surface of bottom seal bar 231 was pressed on the film 101, this projection in fact just was pressed on the film 101.According to the structure of this protruding 231a, being used to of the bag 2000 of can determining to support oneself made the shape of the strengthening rib of bottom hermetic unit 2003, the stability of standing of the bag 2000 of promptly supporting oneself.In the bottom of present embodiment hermetic unit 2003, in the zone of heat-sealing with admit border between the zone of compaction material to form the bend of a bump, and at the above-mentioned zone that will seal with will be by a bend bonded assembly by the border between the end sealing mechanism 260 leak free zones.In addition, make the feed spacing P of protruding 231a length vertically greater than film 101, and make protruding 231a along continuous straight runs that maximum length is arranged in the top and bottom of protruding 231a, thereby bottom hermetic unit 2003 can overlap on two ends of side seals part 2002 (with reference to accompanying drawing 34) of the bag 2000 of supporting oneself.
And then, in protruding 231a, the recessed 231b that does not push down film when heat sealing film 101 is surrounded by protruding 231a and forms, and provide protruding 231a with recessed 231b, their position is the position of not pushing down the in-to-in top region 101c of fold in projection, and described fold is that the outside of the bump 101b in film 101 forms.
According to above-mentioned structure,,, and, film 101 is not sealed in the zone (with reference to accompanying drawing 15) at the top of bump 101b in zone corresponding to the recessed 231b of bottom seal bar 231 when when bottom sealing mechanism 230 heat sealing films 101.Therefore, these zones have become the outlet (storage tank) of the air bubble that produces in the heat-sealing activity, therefore do not have any bubble in the heat-sealing zone, can produce goodlooking suitable heat-sealing.
29 and 30 top seal mechanism 240 is described with reference to the accompanying drawings.
As shown in figure 29, top seal mechanism 240 comprises two cylinder bodies 243 that are fixed on the framework 210b, they have two mutual connecting rod 243a staggered relatively, and comprise two top seal bars 241, each seal bar 241 is all supported by the strut member on the connecting rod 243a that is fixed on each cylinder body 243 242, the pressure surface of top seal bar 241 is oppositely arranged mutually, so that can exert pressure; And the structure of top seal mechanism 240 will make the open end (with reference to accompanying drawing 26) of the film 101 that is folded by film shaped fold mechanism 220 pass through between each top seal bar 241.
Each top seal bar 241 also comprises the heating arrangement (not shown), as electric heater.When this heater heats top seal bar 241, and by driving each cylinder body 243 simultaneously each top seal bar 241 is advanced, just the open end of heat sealing film 101 longitudinally is configured as tubular form to film 101 whereby.
Here, as shown in figure 30, the pressure surface of each top seal bar 241 all has the projecting protruding 241a that forms in shaded area, and when the pressure surface of top seal bar 241a was pressed on the film 101, in fact this protruding 241a was pressed on the film 101.Determine the shape (with reference to accompanying drawing 34) of the top seal part 2001 of self-support bag 2000 according to this protruding 241a planform.In the present embodiment, the upper zone that seal and will connecting by a bend by the border between the part of end sealing mechanism 260 heat-sealing.
In addition, with with the identical mode of situation of the protruding 231a of the bottom seal bar 231 of above-mentioned bottom sealing mechanism 230, make the feed spacing P of the protruding 241a length vertically of top seal mechanism 241 greater than film 101, and at protruding 241a top and bottom projectioies 241a along continuous straight runs maximum length is arranged, so top seal part 2001 can be overlapping at the two ends (with reference to accompanying drawing 34) of the side seals part 2002 of the bag 2000 of supporting oneself.
Therefore, in the present embodiment, for 4 layer segments of keeping film 101 have enough big heat seal strength, 4 layer segments that provide enhanced leaktightness mechanism 250 to come heat sealing film 101, and then application end sealing mechanism 260 seals.
Now, with reference to accompanying drawing 31 and 32 this enhanced leaktightness mechanism 250 is described.
As shown in figure 31, enhanced leaktightness mechanism 250 comprises two cylinder bodies 253 that are fixed on the framework 210c, they have two mutual connecting rod 253a staggered relatively, and comprise two enhanced leaktightness bars 251, each seal bar 251 is all supported by the strut member on the connecting rod 253a that is fixed on each cylinder body 253 252, the pressure surface of enhanced leaktightness bar 251 is oppositely arranged mutually, so that can exert pressure.Each enhanced leaktightness bar 251 also comprises the heating arrangement (not shown), as electric heater.In addition, shown in figure 32, these enhanced leaktightness bars 251 not on whole zone broad ways push down folding film 101, but make the size of enhanced leaktightness bar 251 can push down 4 layer segments that obtain by above-mentioned film shaped fold mechanism 220 folding films 101.When by heater heats top seal bar 251, and each enhanced leaktightness bar 251 is advanced by driving each cylinder body 253 simultaneously, arrival becomes the part of the side seals part of the bag of supporting oneself, and it is parts (in Figure 32, having the part of grid mark) of 4 layers that heat-sealing is applied to film 101.
And then, film position regulating plate 254 is provided above enhanced leaktightness bar 251, the fixed position of regulating plate 254 can enter between two bump 101b of the film 101 that is sealed by bottom sealing mechanism 230 this film position regulating plate 254.Because this structure, stablized the position of film 101, prevented the deviation of the sealing station of the heat-sealing finished by enhanced leaktightness bar 250, and the bond vitrified of (being folded into recessed film surface) between the bottom sealing that prevents to cause by the high temperature that the heat-sealing back occurs at once.
The action of the filling and packing of the shaping of present embodiment, filling and water-tight equipment is similar to first embodiment, has therefore saved detailed description, but followingly also will be described at the certain effects of present embodiment.
As previously discussed, so that be connected on the part by end sealing mechanism 260 heat-sealings by means of a bend by the part of top seal mechanism 240 heat-sealings, also to become maximum by the part place of end sealing mechanism 260 heat-sealings extra in order to arrange by bottom sealing mechanism 230 leak frees with by the seal area of top seal mechanism 240 leak free along continuous straight runs by the partial sum of bottom sealing mechanism 230 heat-sealing.In other words, in will part, have increased the zone that will seal in advance (film wherein the zone of hot adhesion) mutually by end sealing mechanism 260 heat-sealing.Just because of this, when the film 101 by end sealing mechanism 260 heat-sealings is clamped between heater bar 267 and the heater bar holding device 264, in film 101, can produce fold hardly.Thereby can prevent the defective sealing that produces by the fold in the film 101.
Now, manufacturing step according to the self-support bag of producing by shaping, filling and the water-tight equipment of present embodiment 2000, near the part that is sealed by bottom sealing mechanism 230 thickness is greater than the thickness of other parts, because the film 101 that forms in this part is 4 layers.Therefore, if push down film 101 at this state by compression roller 114, will produce fold in film, and produce heat-sealing off quality sometimes, this can influence the performance of end sealing mechanism 260.
Therefore when pushing down film, in film, to produce fold in order preventing, interim constraint mechanism 270 can be provided by compression roller 214.
Though use specific term to describe the preferred embodiments of the present invention, a kind of like this description should be appreciated that just for illustrative purposes, can also make change and variation under the design of the claims below not departing from and the situation of scope.
