Technical field
The present invention relates to a kind of equipment that is used to assemble the insulating glass that is filled with the gas that is different from air.
Background technology
By the known this equipment of EP1450001A1.This known device has on two vertical edges of the plate of assembly equipment the closing means as " first " sealing device, for example rotates valve, and they are hinged on the edge of a plate wherein and can be towards the opposed edge revolution of another piece plate.Conduct " second " sealing device is by a seal of being made up of the strip matrix in the known device, and it covers the band that is lined with elastic foam material system.Seal is in the groove of a wherein bottom-up extension of plate, and can be retracted into the inoperative position at rear, plate surface from one with seal, passes an active position transverse to board plane.This two boards, be hinged on the rotation valve on their vertical edges and " second " sealing device of being located between them constitutes two chambers, insulating glass can be in chamber filling is a kind of is different from the gas of air and assembles.For this reason, chamber for example is filled to the height that is erected at the glass plate in the chamber at least from the below with a kind of gas that is different from air.Wherein, the glass plate vertical edge and and their opposed sealing devices between redundant space also by filling invalidly with this gas that is different from air; When sealing device move to their inoperative position and with the insulating glass that assembles when equipment transports, these unnecessary gases have just lost.
Be used to assemble the equipment of insulating glass by the known another kind of EP0674086A1, this insulating glass is filled with a kind of gas that is different from air.In this known equipment, first glass plate and second glass plate that is provided with distance keeper are erected on the horizontal conveyer of a conveyer belt as conveying element, are transported in the space between the two variable block pressur plates of its spacing.Their location opposed to each other parallel to each other and superimposed between pressing plate, thus distance keeper with and the opposed glass plate of distance keeper between stay the gap of next annular opening.Establish seal on glass plate vertical edge thus arranged side, they act between the pressing plate effectively and extend to the conveyer belt epimere always, and the conveyer belt epimere seals downward space between two glass plates that are erected on the conveyer belt.Introducing a kind of heavy gas (Schwergas) with the vertical seal part between pressing plate between conveyer belt, glass plate, two block pressur plates and effective the work from the below is in the chamber on boundary.Heavily gas rises in this chamber, stops the heavily supply of gas when reaching the packing density of regulation.Wherein a block pressur plate is drawn close to another block pressur plate then, so that seal insulating glass and it is squeezed to preset thickness.
In EP0674086A1 in the disclosed equipment, heavily gas infeed or by the hole in the vertical seal part, or by conveyer belt as conveying element.One of two vertically arranged seals are located near the position of stipulating the leading edge of pressing plate with regard to throughput direction, and, or from the outside closely by on the outward flange that is placed on pressing plate, or it is produced or release from seam with throughput direction with meeting at right angles towards the glass plate leading edge from a near seam that is located at leading edge in one of two block pressur plates, and thus by closely by on the leading edge that is placed on two glass plates.Another seal can and be passed on the back edge that abuts in two glass plates in the space between the rear end insertion pressing plate of pressing plate with regard to throughput direction always.Constitute a chamber in this way, it is boundary and upwards open with the conveyer belt of two glass plates, two seals and horizontal conveyer.In chamber, rise and air is upwards extruded from chamber by conveyer belt or by the heavily gas that one of them seal imports.The shortcoming that exists is, the motion of the antemarginal seal of seal glass plate that can move horizontally needs very complex apparatus of structure, in order that seal can be moved back and forth and spacing that can be different with glass plate suitable.In addition, moving around of seal needs some times, thereby undesirably prolonged the circulation timei of equipment.In the production line inside of making insulating glass, therein a piece glass plate is assembled into insulating glass, with being different from the gas filling of air and the equipment that then compresses, form in the whole production line circulation timei of website the most slowly and decision whole production line usually.Another shortcoming is, can from the seam in one of pressing plate, shift out the encapsulation scheme of vertical seal part by known wherein the relating to of EP0674086A1, and be not suitable for those therein seal be not to act directly on the glass plate edge but act on equipment on the front side that pressing plate faces with each other.
Summary of the invention
The objective of the invention is, from the described prior art of preface, create a kind of equipment that is used to assemble insulating glass, compare with the situation at EP1450001A1, it not only can shorten circulation timei but also can less lose the described gas that is different from air.
The described equipment that is used to assemble the insulating glass that is filled with the gas that is different from air comprises: two blocks of plates opposite each other, this two boards are vertical in parallel to each other or be in tilted layout and this two boards distance to each other is variable; A near horizontal conveyer that the lower limb of plate, is provided with along the plate lower limb, this horizontal conveyer has a throughput direction; At least one first sealing device and at least one second sealing device, described first sealing device and second sealing device extend to position being positioned at horizontal conveyer top and described first sealing device and second sealing device from horizontal conveyer always and have changeable distance to each other along throughput direction, wherein, described at least at least one second sealing device can be located between the two boards; And, the gas that is used for being different from air infeeds the device in the chamber, this chamber in the side be by two boards and by two in first and second sealing devices limit, it is characterized by: each described at least one second sealing device has a band, and this band can be inserted in the space between plate from the top down and can reversibly be compressed by reducing plate distance to each other.
Have at least two from the upwardly extending sealing device of horizontal conveyer by equipment of the present invention, they have the spacing that can change to each other.At least one is called " second " sealing device here and can be located at sealing device between the plate, can be from the top down be inserted into space between plate along the surface that plate faces one another in, and, can reversibly be compressed by reducing plate spacing each other.Its main advantage is:
Act on that sealing device before the glass plate of insulating glass along throughput direction, can be before the glass plate that is assembled into insulating glass by them be positioned between the plate of equipment or during, be placed in its operating position.Therefore, act on the location of the sealing device before the glass plate, can not have influence on the circulation timei of the weak point of equipment along throughput direction.
Should act on the glass plate back edge or near that sealing device along equipment level conveyor delivery direction, can be before the glass plate that should be assembled into insulating glass by them be positioned between the plate of equipment or during, just placed sealing device that best distance is arranged from the front.That is to say, to press the optimum distance location with respect to the sealing device of front, be not that the seal at rear portion sinks to horizontal conveyer always at the sealing device of back, but just can realize still be in the inoperative position of lifting in rear seal during.Therefore the sealing device of back can not have influence on the circulation timei of equipment equally with from the location, sealing device optimum distance ground of front.
Height above the sealing device of back can be during should being assembled into the glass plate location of insulating glass by them have just sunk to its lower end next-door neighbour's glass plate top edge.This also can not have influence on the circulation timei of equipment.
Be positioned between the plate of equipment at glass plate after, be located at antemarginal second sealing device of glass plate at the most again from moving downward the level of horizontal conveyer by the height that they are assembled into the glass plate top edge of insulating glass.This finishes in no time, because second sealing device only needs very little quality, so it has only little inertia and thereby can promptly quicken and slow down.If second sealing device is located on the plate of equipment moving, then it in addition in a pair of glass plate, just can be placed in its active position during the location of second glass plate, thereby the location that makes second sealing device for circulation timei of equipment without any influence.
Can also take measures to win circulation timei, promptly, to be used for the antemarginal seal of glass plate and at first directly not be positioned at glass plate and its rear rim will be positioned at the top of the position here, but be positioned at the place that " first " sealing device from the front has big distance.Then, in case moving on to its rear rim, that piece glass plate of back is used for antemarginal sealing device below, be used for antemarginal that is second sealing device of glass plate, just can move downward and simultaneously near the sealing device of front, thereby second sealing device at glass plate back edge rear can be moved on to its active position always.
Therefore the present invention has realized short circulation timei and the minimum cavity volume that is used to import the gas that is different from air that matches with at that time glass plate length simultaneously.
For disposing " second " sealing device and being effective, needn't disconnect this two boards.
" second " sealing device preferably is designed to, and it can overcome the reset force bending from a kind of shape that is in the relaxed state stretching, extension, and can return to the shape of its stretching, extension under the reset force effect again.This means the shape that it is taked automatically and keeps stretching when second sealing device inserts the space between the two boards from the top.This also means, if make this sealing device free sagging or when a sweptback plate moves backward from the top, then it is tried hard to and also reaches a kind of shape of straight line in normal circumstances.This is favourable for form the situation of determining meticulously between plate.This sealing device is applicable to that the linearity freedom is sagging and need not without barrier in the special space that drops between the two boards until horizontal conveyer with guiding.This form of implementation of the present invention also has another advantage to be, second sealing device is in deflection above the plate and for example can preferably form landing downwards under the situation of pulling in the outside of plate, or also can save ground, position and reel.
For described second sealing device, exist various designabilities.There is a kind of possibility to be, use a sliver transvers section forming V-shape or Z-shaped elastic webbing, it abuts in an one limit on one of two boards, by compression, and causes in this case sealing up to the plate top edge from the horizontal plane of horizontal conveyer when two plates spacing each other reduces.This V-arrangement or Z-shaped elastic webbing can be easy to turn to and reel.
By another kind of form of implementation, the band that each described at least one second sealing device is had is a band that can reversibly compress, its side is connected with flat elastic webbing, elastic webbing is flat to be leaned against on this part or another piece plate, here, the band that can reversibly compress when plate distance to each other reduces by compression and cause sealing effectiveness.
By the another kind of form of implementation of the present invention, the band that each described at least one second sealing device is had is a band that can reversibly compress, it two opposite one another side each is connected with an elastic webbing, elastic webbing is flat when two boards distance to each other reduces to be leaned against on this two boards and causes sealing.
By another kind of form of implementation, the band that each described at least one second sealing device is had is a band that can reversibly compress, and in this band, especially in central authorities, imbeds at least one elastic webbing.This deflection and bending for sealing device is favourable.
By the another kind of form of implementation of the present invention, each this sealing device has an elastic webbing, and it is connected with a band that can reversibly compress at two ends, and band is reserved the edge strip of elastic webbing.Sealing device also can be easy to bending in this form of implementation.Another advantage is that this elastic webbing can and drive in its edge strip place guiding.
The band that can reversibly compress is preferably formed by foamed plastics or by foam rubber.This design is good and cheap, good sealing effect, reliable and long service life.
The another kind of possibility that constitutes a kind of band that can reversibly compress is that band is made of a kind of elastic body hollow profile, and for example the section bar by a kind of cross section rectangle constitutes.This section bar can produce by extruding good and cheaply and some can have been bought on market.They have another advantage to be, even they combine still and can reel easily with an elastic webbing.The compression of hollow profile here can become owing to the regulation folding line of longitudinal extension and be more prone to, and the regulation folding line is located on the wall of hollow profile transverse to the extension of equipment two boards.If the wall that wherein is shaped on the regulation folding line is folded inward on a small quantity in advance, then these regulation folding lines can make hollow profile have the compression of control to carry out especially easily.
Exceeding the elastic webbing that the band that can reversibly compress stretches out in both sides makes the guiding and the driving of " second " sealing device be more prone to.The band that can reversibly compress preferably exceeds elastic webbing and stretches out on a small quantity in the lower end, " second " sealing device can gently meet with horizontal conveyer hermetically and meanwhile thus.Horizontal conveyer preferably has the conveyer belt of a circulation transmission, and it not only carries and be bearing in the glass plate in the equipment, but also the chamber of the gas that is different from air is wherein introduced in sealing downwards.In the described EP1450001A1 of preface this conveyer belt is disclosed for example.It can not only abut on the lower limb of glass plate, and abuts on the lower limb of two boards.
In order it to be stored with saving the locus when the inoperative position of " second " sealing device, top edge at one of plate is established a transfer for each second sealing device, when pull out in the space of second sealing device between two boards, by transfer with it from vertical or approximately perpendicular another direction of directional steering.Transfer is one and has a roller that is parallel to the rotation of throughput direction under the simplest situation.At transfer the outside of the plate at place is set, can second section freedom of the sealing device of pulling out from the space between the two boards is sagging.But preferably, establish the sector-specific storage device that second sealing device is pulled out, pit shaft that extends from the top down especially, second sealing device inserts in the pit shaft, or one from the top down the extension around the guide profile of second sealing device.Second sealing device also can insert in this guide profile, thereby makes it that the position of regulation be arranged and can not clash anywhere.Pit shaft and this guide profile also can be used in combination.
Another kind of possibility is that the upper end of " second " sealing device is fixed on the height of deflecting roller, but from it some distances is arranged, and it can be between deflecting roller, and it is sagging to pull shape in the fixing there place of sealing device.
By of the present invention another further develop, adopt coiler device as storage device.It can appear on the position of aforementioned deflecting roller simultaneously.Coiler device can design by the mode of capstan winch.Yet compared a kind of form of implementation with capstan winch and is preferred, can rotate and push ahead by the mode of mandrel by this form of implementation coiler device, so it can spiral wound and debatching second sealing device.This just can make second sealing device reel with constant curvature.This is favourable, because make the required power of reeling even, the load of elastic webbing is little and even, and increases the service life because help second sealing device.
Also can reach spirality or thread-shaped ground by another kind of form of implementation and store second sealing device, wherein, the guide profile (guiding profile) that storage device has a spirality or thread-shaped to extend, second sealing device can enter its neutralization by transmission device and pull out again.The advantage of this form of implementation is, storage device does not need rotating driving device, but only needs the removable drive of straight line, and the latter after all needs anyway for the location of second sealing device.
Paired driving wheel, driven roller or driving belt are specially adapted to drive second sealing device, they act on the side opposite each other of second sealing device separately, especially act on the edge strip that elastic webbing stretches out, elastic webbing preferably especially is connected by bonding or by vulcanizing with the band that can reversibly compress of as top explanation already.
Paired driving wheel, driven roller or drive belt and be located on transfer or the storage device rightly or near transfer or storage device.Preferably also be provided with some guiding devices there, they determine the radian that second sealing device turns to along it jointly.
Transfer, regardless of their specific design, can be parallel to preferably that throughput direction moves back and forth and meanwhile drive separately second sealing device, make second sealing device move to a position with the length best-fit of the insulating glass that will make as the next one thus along the throughput direction of horizontal conveyer or contrary its throughput direction.Also will add independent storage device if remove transfer, then it preferably moves with transfer.This makes it possible to achieve a kind of cheap and good-quality structure and short circulation timei, and makes second sealing device might be parallel to simultaneously that throughput direction moves and motion up or down.
Preferably, all transfers are placed on the same block of plate.This structurally is best.In most of the cases fixedly mount at one of equipment two boards that is used for assembling insulating glass.Second sealing device and transfer thereof are installed in a minimum expense of needs on this fixing plate.As if then helping shortening circulation timei on the plate that they is installed in motion.
Transfer preferably can move back and forth on a track, and track is placed in one of plate or supports on its top edge of framework.The top edge of plate or its framework is the most suitable to this.
The equipment that has some to be used to assemble insulating glass, in these equipment, two blocks of plates opposite each other can be from their opposed position of forming V-shape each other, is turned back to one and makes them both stand vertically and opposed in parallel with each other position.This equipment is disclosed in EP0615044A1.But be used for assembling the equipment of insulating glass at great majority, these plates are parallel and just in time not vertical but tilt approximately and 6 ° ground arrange, so glass plate can rest on the sweptback plate and carries.In this equipment, described at least one second sealing device preferably is contained on sweptback that piece plate, and this is that piece plate that its inboard sloping floor makes progress.Here the inboard of plate refers to that side that opposed plate faces one another.Therefore the outside of a plate here refer to opposed plate each other back to that side.
If second sealing device is installed on that piece plate that its inboard sloping floor makes progress, the advantage of then bringing is that second sealing device can be non-imposedly by this plate supporting and guiding.But also second sealing device can be installed on its inboard that downward-sloping piece plate.In this case advantageously, some SSs distribute along the inboard of this plate, described at least one second sealing device can be drawn onto on the downward-sloping inboard of plate by them, thereby second sealing device is not oscillated in the space between two boards out of control and also can not clash with glass plate.Swabbing action is adjusted into, second sealing device can be fixed on the downward-sloping inboard of plate, but should not aspirate so consumingly, so that hinder second sealing device to move down thus.A kind of have a sealing device that abuts in the inboard elastic webbing that also slides of plate to be specially adapted to this.
Replacement is drawn onto second sealing device on the downward-sloping inboard of plate, also it magnetically can be fixed on this plate, some magnet that for this reason distribute in the downward-sloping inboard back of plate, and described at least one second sealing device has a kind of elastic webbing of can magnetized material making of usefulness.The magnetically fixing another kind of possibility onboard of second sealing device is that a coating is with in the downward-sloping inboard of plate, and some magnetizable particle or structures distribute in coating or in the coating back; And being provided with at least one on described at least one second sealing device can these particle of adhesive or the magnet of structure.

Fig. 2 represents that second sealing device 7 is near its invalid terminal location, and second sealing device 8 is in its active position, and this moment, it dropped on the epimere of conveyer belt 22 always.
Below by the working method of Fig. 2 to 4 explanation at equipment shown in Fig. 1 to 8.Though Fig. 4 based on the situation of describing among Fig. 3, correspondingly also relates to situation shown in Figure 2, so when key diagram 2 and Fig. 3, all utilize Fig. 4.At first be noted that when only assembling an insulating glass in the equipment and during with a kind of gas filling that is different from air (as representing among Fig. 2), how equipment works.
At first two first sealing devices 5 and 6 and two second sealing devices 7 and 8 are in its inoperative position.One first glass plate 31 is erected on the conveyer belt 22 and rests on first plate, 1 upper edge throughput direction 4 and is transported in the space between two plates 1 and 2.In order to make first glass plate 31 can be smooth along first plate, 1 inboard 1a more easily, first plate 1 be shaped among many figure the not aperture of expression, can pass through their blow air by blast fan, and air causes air cushion between glass plate 31 and plate 1 inboard 1a.First glass plate 31 is transported to plate 2 along near predetermined terminal location throughput direction 4 that edge in front always.If first glass plate 30 has got there, close horizontal conveyer 3.Wherein combination has second plate 2 of the aspirator that does not have expression among the figure, by handling mandrel 16 towards 31 motions of first glass plate, it is held and then leave from first plate 1 again.To have second glass plate 32 that is bonded in the frame shape distance keeper 30 on second glass plate 32 then and be erected on the horizontal conveyer 3 and move to a position, it and first glass plate 31 are opposed superimposedly in this position.
In second glass plate, 32 described position fixing process, one of two second sealing devices 7,8 move on to a position on track 35, and this moment, it was near the back edge of aliging shown in glass plate 31,32 figure.If only plan maybe can only assemble single insulating glass under individual cases in this equipment, then people can locate that second sealing device 7 or 8 that for this reason needs mobile short line.Represent to assemble in the example of a large-sized insulating glass at Fig. 2, its length surpasses half of plate 1 and 2 length, and this should be a sealing device 8.If the controller known glass plate 31 of stepper motor 40 and 32 height, then sealing device 8 also can drop to during second glass plate 32 enters on the height above adjacent glass plate 32 top edges always.If two superimposed each other opposed to each other location of glass plate 31,32, then drop to second sealing device 8 on the conveyer belt 22 always and make second plate 2 near first plates 1, until first glass plate 31 with and its opposed distance keeper 30 between also have for example gap of 2mm to 3mm of a Rack.Band 33 is compressed and causes closed hermetically (see figure 4) between two boards 1 and 2 in this case.In this position, also handle the sealing device 5 adjacent with 32 leading edges and advance its lath 24 with glass plate 31, meet with the plate of fixing 1 with 25 its sealing is soft until it.Fig. 4 has represented described state.In this position, between plate 1 and 2, form a chamber, it below be the boundary with horizontal conveyer 3, be the boundary in the side with plate 1,2 with first sealing device 5 and with second sealing device 8, open to the top.Fig. 2 for example in, described chamber extends via the gap between 3 two section 3a of horizontal conveyer and the 3b.For chamber in this case still is in the state of adequate closure, between two conveyer belts 22, establish a bridge 43 that replenishes sealing.In this chamber preferably from below import a kind of gas that is different from air by the mode that for example among EP1450001A1, illustrates, especially a kind of heavy gas, it rises in chamber and the space between the filling glass plate 31 and 32 meanwhile.If infeeded the heavily gas of q.s, adjust then heavily that gas is supplied with and with movable plate 2 further near fixing plate 1, first glass plate 31 met with distance keeper 30 and bond together with it.When the predetermined nominal thickness of two boards 1 and 2 distance and insulating glass is consistent, finish the motion of second plate 2.
After this, movable plate 2 leaves fixed head 1 again, first sealing device 5 is retracted into its inoperative position, and second sealing device 7 or 8 is withdrawn into its inoperative position, and the insulating glass that assembles is sent from equipment by the driving of horizontal conveyer 3.First glass plate that is used for next insulating glass during this period can be admitted to this equipment.
In the equipment shown in Fig. 1 to 8, also can assemble two insulating glass simultaneously and carry out filling with heavy gas (for example argon, sulfur hexafluoride, krypton or other gas).By Fig. 3 and 4 this is illustrated below.At first all sealing devices 5 to 8 are in their invalid original positions.Be used for first glass plate 31, be transported near its terminal location second plate, 2 leading edges at first always at the insulating glass of Fig. 3 left side assembling.Then, the first glass plate 31a that is used for the insulating glass assembled in the right section of equipment is transported in the space between two plates 1 and 2 and orientates as, makes them near the vertical edges of back is in second plate, 2 back edge.Then these two glass plates 31,31a by with Fig. 2 for example in the plate 2 of the corresponding mode passive movement that illustrates hold and lift from fixed head 1.After this, second glass plate 32 that the insulating glass that is used for assembling in equipment left side district is equipped with distance keeper 30 is transported in the space between plate 1 and 2, and locatees with mode and first glass plate 31 of having illustrated superimposedly.Overlappingly in time, should be combined into second glass plate that second insulating glass is equipped with distance keeper, and be transported in the space between two plates 1 and 2 and and locate superimposedly with glass plate 31a with glass plate 31a.By also synchronously driving two conveyer belts 22 dividually, can save time.
During two glass plate location that have a distance keeper, two second sealing devices 7 and 8 can move to the position that the length of they and glass plate 31 and 31a adapts along track 35, and drop to the elevation-over of getting close to the highest glass plate 31 at least.In case being used for second glass plate 32 of the insulating glass assembled in the district of a left side has passed through set second sealing device, 8, the second sealing devices 8 in the right and just can drop to horizontal conveyer 3 always.If second glass plate 32 of the insulating glass of on the left side assembling also passed through second sealing device 7 that is located at the left side, then second sealing device 7 also can sink on the horizontal conveyer 3 always.Locate in case four glass plates are paired superimposedly, just with movable plate 2 close fixing plates 1, until distance keeper 30 and and its opposed glass plate 31 between the gap reach for example 2.5mm of a predetermined width, second sealing device 7 and 8 band are compressed in this case.Then, two first sealing devices 5 and 6 are advanced to their sealing station, and meet in they and first plate, 1 inboard in this position.Then the described gas that is different from air is injected in two chambers, they below be the boundary with two conveyer belts 22, and in the side with two plates 1 and 2, one end with two sealing devices 5 and 7 and the other end be the boundary with sealing device 6 and 8.If in each chamber filling the gas of q.s, then finish the introducing of gas, compress insulating glass, sealing device 5 to 8 is placed their invalid original positions, send two insulating glass, meanwhile imported follow-up glass plate.
Second sealing device 7 and 8 location are in fact for not influence circulation timei of equipment in this case.The work of this equipment is very reasonable.
Throughput direction 4 is chosen wantonly in each embodiment.It also can be along in the other direction.
The difference of embodiment shown in Figure 9 and the embodiment that introduces above is that second sealing device 7 and 8 is not mounted on the fixing plate 1, and is mounted on the movable plate 2.Recommend to adopt independent measure in this case, be used to make second sealing device 7,8 on plate 2 inboards of motion, to guide, as having set forth in the general declaratives, for example by slight suction or pass through magnetic force.Because the plate 2 of motion is downward-sloping with its inboard, so second sealing device 7,8 can be smooth downwards on second plate framework, 12 outsides with its section externally; Be not leave no choice but to be used for separately the storage device of second sealing device 7,8 can not.Form of implementation shown in Figure 9 is not especially when being to assemble two insulating glass simultaneously and be particularly advantageous when always only assembling an insulating glass between plate 1 and 2, it allows shorter circulation timei, because during second glass plate being positioned between plate 1 and 2 in the space, sealing device 7,8 just can be placed on their active position.Because second glass plate abuts on the fixing plate 1 and carries, so it can be in second sealing device, 7, the 8 other processes of the plate 2 of the motion that reclining.
Figure 10 to 12 expresses a storage device, adopts them to come pit shaft of representing in the alternate figures 5 to 7 38 and the bearing transfer simultaneously of task.It relates to a cylinder 44 of being made up of two disks 45, and disk 45 connects by four struts parallel to each other 46, in their the fixing guide profile of spiral extension (guiding profile) 47 in inboard.Guide profile 47 has a seam that extends longitudinally and follow guide profile 47 spirality tracks respectively in its side.Two two edge strip 34a that fasten elastic webbing along helix seam opposite each other.Cylinder 44 can replace and turns to roller 37 and pit shaft 38 (Fig. 5) to be fixed on the support 36, and support can move on the track above the fixed head 1 35.
Second sealing device 7 and 8 driving, as like that in expression in Fig. 5 and 6, can be still by 39 realizations of paired driving belt when using cylinder 44.Also can be replaced to right driving belt and for example adopt paired driving wheel.Paired driving belt 39 is pulled out second sealing device 7,8 from cylinder 44, so that they are placed its effective seal position, and, they are pushed back in the cylinder 44, so that they are placed its invalid home position.Although they extend on cylinder 44 spiral ground in order to make second sealing device 7,8, still can be accurately move in the space between plate 1 and 2 perpendicular to throughput direction 4 ground, cylinder 44 should be configured to, its longitudinal axis is in the plane that is parallel to fixed head 1, but with respect to horizontal feed direction 4 angle [alpha] that depends on the pitch of cylinder 44 inner vortexs that tilts.
The difference of the embodiment that represents among embodiment shown in Figure 13 and Fig. 4 is that second sealing device 7 is not the flexible band that can reversibly compress 33, and it covers in a side and is lined with flat elastic webbing 34.Exactly, second sealing device 7 is the elastic webbings that Z-shaped cross section is arranged.First limit 48 of second sealing device 7 abuts on first plate 1.Second limit 49 of second sealing device 7 abuts on second plate 2.These two limits 48 are connected by web 50 with 49, and it becomes Z-shaped section bar with two limits 48 and 49 completions.Web 50 bends in such a way at the one end, makes its limit 48 that reclines to the large scale scope on the whole.This makes this limit 48 to guide in the corresponding way in both sides, as the elastic webbing 34 in Fig. 5 to 7 illustrated embodiment for example in front.
