Definitions
- the invention relates to a device for depositing a thin metal film on a surface and in particular on the surface of a sheet, which has the features of the preamble of claim 1. It relates in particular to the preparation of sheets of laminated glass heated by son.
- Wire-meshed laminated glass panes are in particular window panes and the like which have a multilayer structure consisting of at least one rigid pane (glass or plastic) and a layer or sheet of synthetic material which adheres at its surface, several machine-deposited resistance wires being arranged in the boundary surface between the rigid pane and the layer or sheet of synthetic material.
- These wires are generally electrically connected in parallel and are supplied with heating voltage using at least two collectors.
- the collectors generally extend along each outer edge of the pane. In general, leaves equipped with wires are enclosed between two rigid panes.
- European Patent EP 0 443 691 describes a device of this type, for depositing these son on sheets. It comprises a mobile laying device to which the son coming from a coil are brought via an eyelet guide and two toothed wheels which mesh with one another.
- DE 20 43 746 discloses such a yarn laying device which has a yarn guide tube disposed between the yarn spool and the laying location.
- DE 41 01 984 A1 discloses a similar device which has a simple guide between the wire spool and the gears. A Reducing transmission is provided between the gears and the driven roller steadily, which pushes the wires back onto the sheet. The gears rotate slightly slower than the push roller. This ensures that the corrugated wire always remains under a low tensile stress on the path that extends between the gears and the thrust roll. This prevents uncontrolled movement of the deposited wire.
- the sheets to be provided with the wires in these known devices are attached to rotating drums which allow the sheet substrate to be fed more or less continuously beneath the wire laying devices.
- the rotational movement of the drum can also be controlled at different speeds, so that braking or acceleration transitions are obtained.
- the problem underlying the invention is, for a device of the type indicated at the beginning, to further improve the guidance of the wire before laying on the sheet.
- the clamping element ensures a constant tension of the thread before the actual laying operation and possibly before it is corrugated. This greatly reduces the influence of a relatively slow rotation of the spool of stock, in any case when it is fully full, on the subsequent ripple and laying of the thread.
- the yarn is passed into a "buffer zone" (for example with return rollers) to thereby compensate for the change in tensile force at the exit of the buffer zone by appropriate compensation of the force as well. only by compensation of the length of the wire inside the buffer zone.
- a buffer zone for example with return rollers
- a yarn laying device thus equipped is equally suitable for conventionally laying yarns in a uniform manner, with or without corrugation, in regular courses, as well as for laying the yarn according to the paths recently proposed in any curves, in divergent courses. , in non-circular paths of variable radius, with local increases and / or decreases in wire laying density, etc. the clamping device according to the invention deploys its advantages particularly for the laying forms mentioned last, because in this case it is often necessary to order the sheet support at variable speeds. It is even possible (in a manner known per se) to make reversals of the direction of movement.
- FIG. 1 represents an overall view of the device according to the invention, with a drum for fixing the sheet substrate and a single device for laying the wire and
- FIG. 2 represents a view of a device for compensating for the tension of the thread.
- the device according to the invention shown in FIG. 1 comprises a drum 1 which, thanks to a drive 2, forms a moving laying surface for thermoplastic sheets (in particular polyvinyl butyral).
- thermoplastic sheets in particular polyvinyl butyral.
- the sheets 3 with wires are generally placed between two rigid glass panes and / or synthetic material and connect them by adhesion over their entire surface, so that one thus obtains a laminated glazing which can be heated by means of sons.
- the cylindrical drum 1 advantageously has a large diameter and a large circumference, so that one can put several sheets 3 on its cylindrical wall. We can see here two sheets 3 of the same size. They are fixed on the casing surface of the drum preferably by vacuum or pressure difference.
- the envelope surface is provided in known manner with a large number of bores through which the air is sucked. The atmospheric pressure pushes the leaves back onto the envelope surface.
- a device 4 for laying the wire also called the laying head.
- this device can be moved back and forth parallel to the axis of rotation of the drum (and therefore parallel to the direction of examination of the figure) along a rectilinear guide 5.
- a wire 7 is extracted from a spare coil 6 of wire and is finally laid using a thrust roll 8 (preferably heatable) on the sheet 3 or incorporated in the surface thereof.
- the spool 6 of wire reserve can in known manner be equipped with a controllable brake, for example electric brake.
- the thrust roller 8 is preferably prestressed elastically against the casing surface of the drum 1 and rolls without proper drive on the sheet 3.
- the wire 7 passes through a guiding device generally indicated by 9 in FIG. 1. It serves firstly and in a manner known to impart a pattern to zigzag or a ripple in the thread running through it. It is known that a zigzagging of the wires 7 minimizes their visibility in the finished laminated glazing (see in this connection the literature mentioned at the beginning).
- the guide device 9 has for the wire 7 which passes through another clamping device of which Figure 2 gives more details.
- FIG. 2 represents in the same plane the assembly of the guiding device 9 and the path of the wire 7 between the wire reserve reel 6 and the thrust roller 8, because it is a question of only to explain the operation and not to represent a real embodiment.
- the thrust roller 8 has a flat and curved thrust surface. Thread 7 passes on the line of its summit. In this way, the thread 7 is pressed into the surface of the sheet 3 without the side edges of the thrust roll 8 penetrating the sheet 3.
- the guiding device 9 comprises, in a manner known per se, two toothed wheels 10 which mesh with one another and which give the wire 7 guided between them the desired undulation immediately upstream of the thrust roll 8. To simplify the waviness of the wires laid on the sheet 3 has not been represented. With regard to the relative speed between the gears and the thrust roll, reference is made to in the state of the art described above.
- the wire 7 passes into a clamping device generally designated by 11.
- the latter comprises two fixed guide rollers 12 and between them, a clamping roll 13 movable and elastically prestressed.
- the latter is rotatably mounted in the clamping device 11 and / or in the guiding device 9 on an oscillating or pivoting lever 14 which itself is prestressed by means of a thrust spring 15. It is shown in broken lines. different possible positions of output of the pivoting lever 14 out of the central position shown in solid lines.
- the guide rollers and the clamping roller can also be replaced by sliding guides if the wire can slide over them with negligible friction. They are not excluded, even if in the following we always talk about rollers.
- the invention makes it possible to obtain a reaction as sensitive and as close as possible to the clamping device 11 to variations in the instantaneous tension of the thread.
- a particularly small mass of moving parts of the clamping device and low friction in all mounting locations and possibly slip can make a particularly interesting contribution in this regard.
- the wire 7 forms a U-shaped loop whose depth relative to the guide rollers 12 is defined by the effective position of the movable clamping roll 13 which is held under stress speak 15.
- This loop allows a fairly large compensation of the length, several centimeters, in the part of the wire which is at any time between the wire reserve coil 6 and the thrust roller 8.
- the clamping roller 13 (elastically prestressed) can also be guided in a straight line in an easily accessible sliding guide, in opposition to an elastic force or the like, instead of be by the pivoting lever shown, so as to extend over a greater length without angular offset.
- the wire 7 passes again between two guide rollers 16 which enter it exactly in the middle between the toothed wheels 10. These can obviously also be replaced by the sliding guide or even be completely removed if, starting from the second guide roller 12, the sufficiently accurate introduction of the wire 7 between the gears 10 is guaranteed.
- any other embodiments of maintaining a voltage can be used. wire, even in these locations, provided that the conditions mentioned above (as well as the congestion data and the possibility of adjusting the wire tension) have the same effect.
- a movable sliding rail instead of the clamping roller if it is expected that it will compensate for a difference in length too important.
- These sliding rails are known on chain or belt drives. They extend longitudinally in a curve whose radius of curvature changes as a function of the tension of the thread passing therethrough.
- helical thrust spring 15 shown schematically here, it is also possible to use other adjustment means of the clamping roller 13, for example a pneumatic spring, a pneumatic adjustment drive, electrical or the like.
- the clamping device may optionally also include a measuring unit (not shown here) which determines the effective tension of the thread which then imposes the necessary clamping force at all times on an associated setting drive.
- a measuring unit could for example detect the force exerted on its bearing by one of the return rollers 12, which force increases when the drum 1 accelerates and decreases when the drum 1 slows down. When the force on the wire is reduced, it will then be necessary to exert a complementary tightening, while in case of rise of the tensile force, the tension can be reduced.
