Description

Rotary sealing system
How to the invention relates to heat energy is applied to apparatus and method on the workpiece, such as the welding that is used for workpiece, sealing, cutting etc.More specifically, the present invention utilizes ultrasonic energy to handle such as disposable diaper, sport pants, feminine care products, feminine care and incontinence garments etc.
Utilize the mechanical oscillation that produce under the ultrasonic frequency to come the welding heat plastics, be a kind of full-fledged industrial manufacture process plastic embossed pattern and shaping.The civilian therewith described invention of physical principle of this technology institute foundation has important relationship, therefore is worth briefly introducing and discussing.
In order to obtain tangible vibration, most of ultrasonic systems are being worked under one its vibration frequency totally.Supersonic generator is designed at identical frequency low-resonance with the ultrasonic wave beak iron, and the vibration of supersonic generator generation propagates into beak iron like this.Because it is consistent with generator that the frequency of beak iron transfers to, so the expansion that it is gone up along its length is consistent with the motion that contraction and vibration machine are applied in.
The motion that produces on the beak iron scope of freedom is reciprocal, promptly on perpendicular to the plane on beak iron surface before and after motion, amplitude is by the voltage decision that is applied on the vibration machine crystal.Known already that the vibration that how before vibration propagates into beak iron generator is produced regulated, and comprised expansion instrument and phase change device are attached among the serial mechanism that is applied to this purpose.
The ultrasonic vibration of resonance is being applied to a restriction that problem is the beak iron width that runs in the continuous production.Although beak iron mainly is to shrink and extensional motion on its working face, beak iron is wide more, and promptly its working face is long more, and generally the oscillation amplitude change along the vibration of face length direction is just big more.Therefore, handling the workpiece that is the continuous web shape with ultrasonic energy can only be limited to two kinds of technologies usually.
In first kind of technology, the ultrasonic wave beak iron of a rotation that is placed on the fixed position applies ultrasonic energy near the anvil that places its below, anvil then basically along a straight line of the workpiece that moves, along vertical beak iron of workpiece through rotating.This technology is existing the description in the United States Patent (USP) 3,222,235 of Buchner.
Second kind of technology is that one or several static plane or the ultrasonic wave beak iron that is commonly called insert type extend along the width of fabric direction, when fabric at static beak iron with place accordingly between the anvil under it when mobile, ultrasonic energy is applied to all of fabric or the part of selecting, United States Patent (USP) 3 as people such as Grgach, 939,033 and people's such as Long patent 3,733,238 in narration respectively.The insert type beak iron may mean that it moves, yet in fact beak iron may be static, but fabric is shifted to it.
In first kind of change form of second kind of technology, people's such as Abel United States Patent (USP) 4,713,132 have introduced the beak iron that a series of planes are installed rotates its fixing axle around the anvil cylinder that is placed on rotation, and beak iron rotates like this and makes beak iron contact or disengage with workpiece on the fabric.
In second kind of change form of second kind of technology, people's such as Mahoney United States Patent (USP) 4,650,530 is introduced the fabric of the edge fold workpiece of the Moving plate that rotates, and produces the ultrasonic wave beak iron, and when beak iron rotated on dish, corresponding anvil alignd with workpiece.Beak iron and anvil are planarized structures.Beak iron rotates with anvil and dish, makes by a position in the free space between the projection that radially extends on dish and respectively overlaps beak iron and anvil facing to separately workpiece, and ultrasonic system acts on the workpiece.The dish that carries workpiece does not so participate in applying ultrasonic wave energy, and the vibration-direction of ultrasonic wave beak iron is just in time consistent with the bearing of trend of the axle of the rotating disc that carries workpiece.
Second problem of plane ultrasonic wave beak iron is, for the length direction along beak iron evenly applies ultrasonic energy, beak iron leaves the distance of anvil and must align along the surperficial two dimension of beak iron, makes the working surface of beak iron such as the working surface that accurately is parallel to anvil.Especially such as beak iron or anvil continuous motion is arranged, rather than ultrasonic vibration, under the situation of rotating such as in beak iron or the anvil or both, thisly be aligned to a dynamic problem accurately, required continuous monitoring and repeat to adjust distance between beak iron and the anvil.
The present invention is intended to overcome these problems, and by according to the energy system of claim 1 independently and 39 and further by the method in the claim 25 and 36 independently, has realized this target.
From relevant claim, explanation and accompanying drawing, can see further advantage of the present invention, feature, content and details significantly.In general, claim should be understood as that it is to define first method of the present invention on the whole, and is not its limitation.

Programmable limits switch 88 also is installed on the driving shaft 50, and its purpose back is illustrated.The output of programmable limits switch 88 is delivered to control cabinet 78 by electric wire 90.
Wish that operation of the present invention and function are clear fully by element described above and the relation between them, but disclosure is more complete in order to make, and will briefly explain use of the present invention.
Change now and see Fig. 4, driving shaft 50 makes end flange 48, working drum 26, and back-up roller 38 and its support planker 62, ultrasonic wave supports subassembly 64, and ultrasonic wave beak iron 70 and generator 72 rotate with stable rotating speed continuously.The live-rollers 92 of coming in is positioned at lays the station, and with respect to the reference line by axis 28, the angle on the periphery of working drum 26 " P " is located.The fabric 33 of workpiece or other materials move into the live-rollers 92 that comes along direction shown in the arrow 93 and are admitted to, thereby when working drum when direction shown in the arrow 94 is rotated, the roll gap place fabric that forms between working drum 26 and live-rollers 92 engages with the working surface 32 of working drum 26.Fabric 33 general on the outer working surface of working drum the periphery around working drum 26 be pulled, from the live-rollers 96 that live-rollers 92 beginnings of coming in arrive out up to it, the latter is positioned at the station of taking off that angle " R " on the periphery of working drum 26 locates.At live-rollers 96 places of coming out, rotate action roller 92 of fabric 33 rotates, and as shown in this place's fabric 33, thereby is taken off from working drum, and has left the technology that the present invention was concerned about.
Usually, when putting into practice when of the present invention, the ultrasonic wave beak iron is by continuous agitation, with their design frequency resonance.
Change the combination of 3-7 with the aid of pictures, channel opening 98 extends by the outer wall 46 of the back-up roller 38 of close each planker supporting rail 60.Pair of cams follower 100 extends downwards from each planker separately, passes channel opening 98, engages with cam floor 56.Therefore, when working drum 26 and back-up roller 38 on the axis 28 when fixing cam roller 54 is rotated, cam-follower 100 and engaging of cam floor 56 make planker or towards or move away from the outer working surface 32 of working drum 26.For per 360 rotations of spending of working drum 26, each planker is made a complete circus movement towards working drum 26 with away from working drum 26 like this.Therefore, referring now to Fig. 3-5, the planker 62A 12 positions on the back-up roller 38 extends towards working drum 26 fully; Planker 62B 6 positions on the back-up roller 38 withdraws from working drum 26 fully.
When planker 62 when working drum 26 extends, ultrasonic wave beak iron 70 separately extends on the outer working surface 32 of working drum 26 and corresponding anvil bar 34.When planker 62 when working drum 26 is withdrawn, ultrasonic wave beak iron 70 is separately withdrawn from the outer working surface of working drum 26.
When ultrasonic wave support fitting 64, the outside far away of the combination of beak iron 70 and generator 72 101 is during inwardly through the inboard 102 of live- rollers 92 and 96, thinks that ultrasonic wave beak iron 70 withdraws from outer working surface 32 fully.Referring to Fig. 4, the beak iron 70 on its middle carriage 62B is withdrawn fully, than the definition " withdrawing fully " position also further from working drum 26.Therefore, " withdrawing fully " is interpreted as the scope of position in the outside 101 of the inboard of the inboard 102 that is positioned at live- rollers 92 and 96, is not limited to this place's planker is positioned at highest distance position with respect to working drum 26 position.
When planker 62 extends towards working drum 26, and when each ultrasonic wave beak iron 70 correspondingly is positioned at outer working surface top, programmable limits switch 88 sends signal to compressed air control cabinet 78, thereby activate cam 103, cam 103 is extended on cylinder 76 separately, the ultrasonic wave beak iron 70 of each resonance is moved downward, shown in the double-headed arrows of 104 expressions among Fig. 7, on each anvil bar 34 separately, contact with the workpiece that just is being transported in the fabric 33 on each workstation1 06 of definition.The ultrasonic wave beak iron that rotates is applied to downward power the support resistance of keeping out anvil bar 34 on the workpiece.The size of downward power is controlled by the power that acts on the cylinder 76.
Along with the ultrasonic wave beak iron 70 of rotation of resonance so is applied to downward power on the workpiece, when ultrasonic wave beak iron 70 when energy applies in the path 108 laterally through working surface 32, because it is applied to ultrasonic energy on the workpiece effectively moving point 112 places cross workpiece gradually, makes the circular beak iron 70 that rotates be allowed to and can rotate around axis 110.As shown in Figure 4, energy applies the path and can extend to less than whole distances of crossing fabric 33, perhaps can extend whole distances of crossing fabric 33, and this depends on that ultrasonic energy carries out the length of the support arm 68 of what work and planker supporting rail 60.
When beak iron 70 laterally applied the part of coming out in path 108 through energy, ultrasonic wave beak iron 70 preferably was pressed down to becoming work to contact with workpiece.When each ultrasonic wave beak iron 70 arrives energy and applies the outermost end of the part of coming out in path 108, limit switch 88 detects the position of workstation1 06 with respect to each relevant angle of axis 28, and send signal to compressed air control cabinet 78, the part of coming in (oppositely) that applies path 108 at energy when beak iron 70 goes up by when workpiece is withdrawn, and promotes beak iron 70 from workpiece.Referring to Fig. 5, beak iron 70 is located beginning in the angle on the periphery of working drum 26 " E " and is extended on cylinder 26, promptly begins to pass the inboard 102 of live-rollers 92,96, angle on the periphery of working drum 26 " W " is located, and beak iron is withdrawn from outer working surface 32 fully.Referring to Fig. 5, each workpiece in fabric 33 arrives before the live-rollers 96 as can be seen, and each beak iron accessory is withdrawn fully, and workpiece and fabric 33 are taken away from working drum 26 at live-rollers 96 places.Similarly, the beak iron accessory that comprises beak iron 70, generator 72 and ultrasonic wave support subassembly 64 keeps withdrawing from fully, do not begin to extend on the working surface 32 outside, passed through the live-rollers 92 of coming in up to the beak iron accessory, and outer working surface 32 engages with the fabric 33 of the workpiece of coming in again.
Working drum 26 rotates continuously like this, and ultrasonic wave beak iron 70 then accompanies.Workpiece enters ultrasonic system 24 when workpiece is placed on the working drum 26 as the part of fabric 33, when the ultrasonic wave bringing device, when forming weld seams 22 such as beak iron 70 and anvil 34, workpiece laterally takes off operating path 114 between the position through the riding position located in angle " P " with what angle " R " was located.Working surface 32 outside each beak iron 70 extends through on each anvil 34 like this is with respect to each rotation weld seam 22 of formation in workpiece of working drum 26.Weld seam 22 extends along traversing machine direction.In any given time, the device of combination can be supported on all corresponding workpiece on all workstation1s 06 between the live- rollers 92 and 96 on the cylinder 26 and carry out welding, cutting or similar operations, make each beak iron 70 " withdrawing fully " enough gaps be arranged, so that make the fabric 32 that has the workpiece that processes can be removed at live-rollers 96 places from outer working surface 32.
Suitable rotation ultrasonic wave beak iron is the beak iron of being introduced such as in the United States Patent (USP) 5,110,403 that resembles Ehlert, is used as reference because it is introduced in this invention about suitable this ultrasonic wave beak iron 70.Suitable supersonic generator 72 ultrasonic equipment relevant with other can obtain from a lot of suppliers, such as Sonic power company, Danbury, Connecticut.
Fig. 8 represents another embodiment of the present invention, and wherein, ultrasonic wave beak iron 70 is arranged in the position of putting upside down mutually with the embodiment of Fig. 3-7 with the anvil 34 that matches.Like this, embodiment in the comparison diagram 8 and the embodiment that describes in more detail with reference to figure 3-7, in Fig. 8, the insert type ultrasonic wave beak iron 170 of a pair of routine has replaced anvil bar 34 and has been installed in the working drum 26.Necessary many insert type beak irons 170 can be used to apply the whole width in path 108 across energy.Correspondingly, the anvil 134 of rotation has replaced the ultrasonic wave beak iron 70 that rotates and has been installed on the ultrasonic wave support fitting 64.
In use, ultrasonic wave beak iron 170 preferably can continuous pump in operational process of craft.Working drum 26 and back-up roller 38 rotate continuously, as described above.When cylinder rotates, anvil 134 extends on working surface, and when anvil 134 laterally applied the part of coming out in path 108 through energy, anvil 134 became work to contact by cylinder 76 and workpiece, when anvil 134 laterally applies the part of coming in path 108 through energy, promote anvil 134 from workpiece.Serious difference is that the position of ultrasonic wave beak iron 170 and anvil 134 puts upside down, and extends on the working surface 32 outside and the physical motion role that withdraws subsequently still obtains embodying on the element that is installed on the planker 62.Therefore, the ultrasonic wave bringing device that is installed on the outer working surface 32 of working drum 26 provides the device of ultrasonic energy, rather than is installed in ultrasonic wave and supports ultrasonic wave bringing device on the subassembly 64.
Perhaps, other energy applicator can substitute ultrasonic unit.These devices comprise stratie, electric inductor element and fluid heat transferring element.
