Description

The invention relates to a device for severing an adhesive bead of a disk, with a motor-driven winding device, with a coil for winding the cutting means for severing the adhesive bead.

The invention further relates to a method for severing an adhesive bead of a disk, wherein a cutting means is guided around the adhesive bead from the outside, a first end of the cutting means is fixed, a second end of the cutting means is passed through the adhesive bead and secured to the winding device , And the winding device for winding the cutting means is driven to cut through the adhesive bead.

A device and a method of the type mentioned above are known from DE 10 2006 013 417 A1 known.

The device and method are suitable for cutting pasted-in panes, e.g. in motor vehicles, buildings, railway trains, cable car cabins, aircraft and ships. Although this application is primarily concerned with an application in relation to vehicles, this is only an example, but not to be understood as limiting.

In modern motor vehicles, the windscreens are connected by an adhesive bead of a polyurethane adhesive or other suitable adhesive firmly with a circumferential body flange. The adhesive bead consists of such a strong adhesive that in conjunction with the windshield, the mechanical stability of the vehicle is increased. It is understood that the separation of the adhesive as a result of its high strength and toughness is thus relatively complex.

However, since windshields must be replaced relatively frequently as a result of stone damage or other damage, it is necessary to provide for each vehicle a suitable device or a suitable method for vitrification of the windshield.

According to the known method, the winding device is supported by means of a support on the frame or body flange or on the adhesive bead, while the winding device is driven in order to cut through the adhesive bead bit by bit. In this case, the winding device is guided along with the support according to the progress of the cutting process on the frame or on the adhesive bead.

A disadvantage here, the elaborate leadership of the winding device has been found along the body flange. Partly access to the body flange is hindered by protruding components. In addition, there is a considerable effort in the leadership of the winding device along the body flange. Furthermore, there is a risk that the body flange is damaged by the leadership of the winder with the support.

From the DE 297 11 291 U1 Further, a disc separator for cutting an adhesive bead of a bonded disc is known, with a pair of suction plates, which are attachable to the disc to be separated, wherein a take-up device is connected via a respective hinge mechanism pivotally connected to the suction plates, and wherein each hinge mechanism a Movement between the suction cup and take-up device by two to the surface of the disc substantially parallel, mutually perpendicular axes permits.

Although such a device is basically a separation of a disc possible, however, the determination of the disc separator with a pair of suction plates is very complex. In addition, it is often necessary to implement the device, since the geometry can be very unfavorable.

Against this background, the invention has for its object to provide an improved device for severing an adhesive bead of a disc, with the simplest possible and power-saving severing of the adhesive bead of a disc is possible.

Furthermore, the simplest possible method for severing the adhesive bead of a glued disc should be specified.

This object is achieved in a device according to the aforementioned type in that the winding device is releasably held via a coupling to a fixable on the vehicle interior suction cup.

The invention is completely solved in this way.

With the device according to the invention namely results in a particularly simple and power-saving way to cut through the adhesive bead, since the winding device can be fixed due to the detachable attachment to the suction plate in a simple manner on the suction cup.

In a preferred embodiment of the invention, the winding device is rotatably received on the suction cup.

In this way, there is a particularly convenient way to remove a disc, since the winding device automatically aligns with the cutting means during the drive of the winding device, so that the adhesive bead is severed in a simple manner.

Since only a determination of the winding device by means of a suction plate on the disc is necessary, results in a particularly simple and energy-saving work, since the winding device does not have to be performed by hand, but is set directly to the vehicle interior.

For the purposes of this application, "cutting means" is to be understood as meaning any wire or even any cord which is fundamentally suitable for severing the adhesive bead of a disk. This means that the cutting means must have sufficient resistance to tearing and bending and, if appropriate, be provided with a suitable coating or suitable surface features in the form of tooth approaches or the like in order to assist the cutting process. It is understood, however, that the term "cutting means" is also to be understood as a suitable cord made of plastic or the like.

According to a further embodiment of the invention, the coupling has a coupling element in the form of a radially outwardly projecting from a pin flange and an associated counter-coupling element in the form of a keyhole, which allows a recording and a displacement of the coupling element in an end position in which the coupling element rotatable is held on the coupling counter element.

In this way, a simple and quick attachment of the winding direction by means of the releasable coupling on the suction plate is made possible from the vehicle inside. The End position can also be secured by a locking means, so that the coupling element is secured against slipping out easily.

According to a further embodiment of the invention, the coupling is rotatably received on the suction plate or on a housing of the winding device.

In this way, the coupling itself does not have to allow rotation between the winding device and the suction plate, but the rotatability is provided by separate means. As a result, there is a broader design options with respect to the coupling.

According to a further embodiment of the invention, a means for securing the clutch against disengagement during rotation is provided.

While the coupling is usually secured against slipping out when rotation relative to the suction cup is limited only by a limited angular amount of e.g. 180 °, so also a complete turning of the winding device by an angle of more than 180 ° or up to 360 ° can be made possible. For this purpose, a locking means may be provided. Also, for this purpose, the coupling may be formed by a corresponding configuration of the associated coupling elements.

According to a further embodiment of the invention, a means for attaching one end of the cutting means is provided on the suction plate.

While the cutting means according to the from DE 10 2006 013 417 A1 had known procedures from the outside about to be attached to the windshield wiper shaft, a fixation on the suction cup itself is now possible in this way. In this way, it is not necessary to attach the cutting means approximately at a hard to reach place of the body. Rather, the suction plate used anyway can be used for attachment of the cutting means. It is understood, however, that for this purpose, a separate suction cup can be used.

According to a further embodiment of the invention, a clamping device for fixing the cutting means is provided on the suction plate.

In this way, results in a simple and quick attachment of the cutting means on the suction cup.

For this purpose, a block with at least one opening, preferably a plurality of openings, for receiving one end of the cutting means and for clamping by means of a clamping element, preferably by screwing, may be provided on the suction plate.

For clamping the cutting means is about a screw used, the end face clamps when screwing the end of the cutting means.

This mounting option can also be combined with the execution of the coupling counter element as a pin with a radially outwardly projecting flange. As a flange or pin, a correspondingly shaped screw can be used for this purpose.

In an alternative embodiment of the invention, a quick-clamping device is provided, in particular a curry clamp, in order to fasten one end of the cutting element.

Also in this way a simple and quick attachment of the cutting means is possible.

According to a further embodiment of the invention, one, preferably at least two guide rollers for guiding the cutting means to the coil is provided.

This measure has the advantage that the cutting means regardless of the position of the winding device relative to the removal point of the cutting means on Adhesive bead is always aligned in an optimal manner to the coil to ensure an orderly winding on the spool.

If two guide rollers are provided, they are preferably mounted on axles which span a plane arranged such that the plane in question runs essentially parallel to a coil axis through the coil. The cutting means is preferably wound substantially tangentially on the spool.

So a clean winding of the cutting means is always guaranteed.

In an advantageous embodiment of the invention, two guide rollers are mounted on axes such that their axes span a plane which is arranged substantially parallel to an axis through the coil of the winding device.

In this way, the cutting means is fed substantially perpendicular to the coil. As a result, the winding of the cutting means is facilitated.

Further, each guide roller is preferably provided with guide surfaces for guiding the cutting means substantially tangential to the coil in an opening of a coil housing of the coil.

In this way, the cutting means is safely fed to the coil from essentially any point on the curve described by the peripheral adhesive bead, whereby the device can be operated in a multidirectional manner and thereby the cutting angle can be positively influenced by displacing the device.

According to a further embodiment of the invention, a support is added interchangeably to the winding device.

In this way, for areas of the adhesive bead, which can not be removed with the winding device attached to the suction plate due to an unfavorable geometry or only very bad, the winding device can be removed from the suction cup. Now, the winding device with the help of the support on the associated body flange are guided along the disc, so as to allow a separation of the adhesive bead in these areas.

Also, this design can be used, if you work with the support and the winding device must be implemented in an interruption. The coupling can then be used for temporary suspension before continuing to work elsewhere.

It is understood that a guide of the winding device along the vehicle body by means of the support can be partially combined with a drive of the winding device, which is rotatably mounted on the suction cup.

The invention is further achieved by a method for severing an adhesive bead of a disk with the following steps:

• Passing a cutting agent around the adhesive bead from the outside;
• Attaching a first end of the cutting means;
• Attaching a motor-driven winding device by means of a coupling rotatably mounted on a suction plate on the vehicle interior side;
• Passing a second end of the cutting means through the adhesive bead and attaching to the winding device and
• Driving the winding device for severing the adhesive bead, wherein the winding device aligns with the cutting means.

In this way, a simple and power-saving separation of the adhesive bead is possible. Since the winding device aligns itself on the cutting means, results a relatively good cutting action due to a favorable orientation of the winding device.

In an advantageous embodiment of this method, the first end of the cutting means is passed through the adhesive bead and attached to the disc.

For attachment, the suction cup can be used for this, which also serves to accommodate the winding device.

In this way, a particularly simple definition of the end of the cutting means, so that can be dispensed with a possibly cumbersome attachment of the cutting means about the windshield wiper shaft.

a modification of the in the FIGS. 1 and 8th The method shown, wherein the winding device is performed for severing the adhesive bead by means of a support along the body flange.

In Fig. 1 a device according to the invention is designated overall by the numeral 10.

The device 10 comprises a winding device 24 for winding up a cutting means 18, which serves for severing an adhesive bead 34 of a disk 12.

The pane 12 may be, for example, a windshield of a motor vehicle, which is glued to a body flange 14 by means of the adhesive bead 34, which consists of a very tough plastic material, such as polyurethane adhesive. The adhesive bead 34 is extremely stable and contributes to the inherent stability of the vehicle.

If such an adhesive bead 34 is to be severed by means of a cutting means in the form of a wire or the like, it is obvious that a considerable force is necessary for this purpose.

While in the state of the art this has generally been done with hand-held winding devices, the invention now proposes a motor-driven driveable Winding device 24, which can be rotatably attached to the disc 12 by means of a suitable coupling 15 to a suction plate 19.

To cut through the adhesive bead, the cutting means 18 is first placed around the disc 12 from the outside and fastened at a first end to a stationary vehicle part, for example on the windshield wiper shaft 13. Then, a second end is passed through the adhesive bead and now attached to the winding device 24. The winding device 24 is rotatably attached to the suction plate 19 in a manner to be explained below by means of a suitable coupling 15. For this purpose, a coupling element 16 and a counter-coupling element 17 are provided which allow a detachable connection and at the same time ensure a rotatability of the winding device 24 relative to the suction plate 19.

If the winding device 24 is actuated, then it turns out of the original, in Fig. 1 shown in exploded position in the dashed line, which is designated by 24 '. The adhesive bead 34 can now be gradually severed by winding the cutting means 18, wherein the winding device 24 always automatically aligns with the cutting means 18.

The structure of the winding device 24 is now based on Fig. 2 explained in more detail.

The winding device 24 has a housing 20, at one end of a handle 22 is provided. Starting from the handle 22, the housing 20 tapers approximately wedge-shaped toward the opposite end, to which a support 32 is removably attached. A spool 28, which is rotatable about a spool axis 72, serves for winding up the cutting means 18. The spool 28 is encapsulated in a contact-proof manner to the outside and has only one opening 70 for the passage of the cutting means 18 outwards. In order to ensure the most tangential possible winding of the cutting means 18 on the spool, two guide rollers 50, 52 are adjacent to each other on fixed axes 58, 60, which receives a passage of the cutting means 18 allow outward from the opening 70. In order to avoid jumping out of the cutting means 18 out of the gap between the two guide rollers 50, 52, the two coil axes 58, 60 are connected to one another by a cover element 64.

The two axes 58, 60, on which the guide rollers 50, 52 are mounted, span each other on a plane which is arranged parallel to the coil axis 72. Such an arrangement of the guide rollers 50, 52 with respect to the spool 28 ensures a largely tangential winding of the cutting means 18 on the spool 28, independently of the arrangement of the spool 28 itself. The coil 28 may, as in Fig. 2 represented, with its coil axis 72 approximately parallel to the cover member 64 and parallel to the outer handle 22 may be arranged.

However, it would also be conceivable, for example, for an arrangement of the coil 28 rotated by 90 °.

The winding device 24 is motor-driven by means of a drive 26. The drive 26 comprises an electric motor 27, from which a gear 29 is driven, which is finally coupled to the coil 28.

In the illustrated case, the power supply of the electric motor 27 is an accumulator, which is indicated by the numeral 30. It will be understood, however, that a net-driven embodiment may be used instead, and that other types of drive, such as e.g. a compressed air motor can be used.

On the upper side of the housing 20, a coupling element 16 is further provided in the form of a keyhole, in which a corresponding coupling counter-element (in Fig. 3 to 6 ) is insertable and can be fixed by moving into an end position.

The associated counterpart coupling element, indicated generally at 17, is in FIG Fig. 3 shown. The coupling counter-element 17 has a pin 35, from the end of a flange 36 protrudes radially outward. The flange 36 can in the assigned wide position of the keyhole-shaped coupling element 16 are introduced and then moved along the narrower portion of the coupling element until an end position results. In the end position 16 can be ensured by a particular embodiment of the coupling element latching, including, for example, two small cams or a suitable spring element can be provided. In this end position, the counter-coupling element 17 is rotatably received on the coupling element 16. From the construction of the shape of the keyhole ago rotation is at least possible by 180 °. As far as a rotation of more than 180 ° is desired, this can be achieved by another form of the coupling element 16 or by an additional securing device (such as the locking means mentioned above).

Hereinafter, various embodiments of the suction cup 19 based on FIGS. 3 to 7 explained.

In the execution according to 3 and 4 For the sake of simplicity, the illustration of a tensioning lever for suction attachment of the suction plate 19 has been dispensed with.

In Fig. 4 is a modification of the suction plate 19 according to Fig. 3 represented and designated overall by numeral 19a. Here, in addition to the coupling counter-element 17a, which in its execution completely the coupling counter-element 17 according to Fig. 3 corresponds, a means for clamping attachment of one end of the cutting element 18 is provided. For this purpose, a block 38 is fixed on the surface of the suction plate 19a, in which a plurality of radial bores 40 are provided. The radial bores 40 allow one end of the cutting means 18 to be inserted. For fixing serves a clamping screw 39 which is rotatably received in an associated threaded bore of the block 38 and can clamp an inserted into a bore 40 with its end face end.

In Fig. 5 a further modification of the suction plate 19a is shown and designated overall by the numeral 19b. Here are the coupling counter element on the one hand and a clamping member for fixing one end of the cutting means 18 on the other hand combined in a single unit. For this purpose, a block 38 is received on a surface of the suction plate 18b, at the lower end in turn a plurality of radial bores 40 is provided, which are designed to receive one end of the cutting means 18. In the block 38, a screw 36 b is screwed, the screw head is formed in the shape of the flange 36 and 36 a, so as to serve as a counter-coupling element to the coupling element 16. The shank of the screw 36b, which is in Fig. 5 35b, corresponds in shape and size to the pin 35 in FIG Fig. 3 , At the lower end of the screw 36 b, a suitable thread is provided, which is screwed into an associated threaded blind hole of the block 38 to clamp an inserted end of the cutting means 18 frontally while ensuring a determination at the block 38. In this way, in combination with the block 38 results in a coupling counter-element 17b.

Additionally is in Fig. 5 nor a clamping lever 42 is shown, which serves to actuate the suction cup 19b.

Another modification of the suction cup is in the FIGS. 6 and 7 represented and generally designated 19c. Here, the functions of the coupling counter-element 17c on the one hand and a clamping device 44 for fixing one end of the cutting means 18 are decoupled from each other.

This is according to Fig. 7 the clamping device 44 designed in the form of a quick-clamping device, which is also known under the name "Curryklemme". The quick-clamping device 44 has two relatively movable terminals 45, 46 which are pivotable about associated axes 47, 48 and are spring-loaded in a suitable manner. If the two clamps 45, 46 are moved towards one another in the direction of the arrows at the ends, the cutting means 18 can be pulled out of the intermediate space between the two clamps 45, 46. In the unlatched state, however, in the space between the two terminals 45, 46 guided into the end of the cutting means 18 is permanently between the two terminals 45, 46 held. According to Fig. 6 extends above the quick clamping device 44, a substantially U-shaped bracket 43, the base on its upper side for receiving a counter-coupling element 17c of Fig. 3 forms known type. One end of the cutting means 18 can thus be clamped to the quick-clamping device 44, the ends of which protrude outwardly from the opening formed by the bracket 43, while the provided on the upper side of the bracket 43 coupling counter-element 17c for connection to the coupling element 16 is used.

In Fig. 8 an insert of the winding device 24 is shown for severing the adhesive bead 34, wherein in a modification to the illustration according to FIG Fig. 1 one end of the cutting means 18 is fixed directly to the suction plate 19 a by means of a suitable clamping device on the block 38. In order to enable attachment of the end of the cutting means 18 on the suction plate 19a, the end is thus pierced through the adhesive bead 34 and then attached directly to the suction plate 19a on the clamping device. Fig. 8 shows the severing of the adhesive bead 34, wherein the winding device 24 from an inactive position 24 at the beginning of the winding directly aligns with the cutting means 18 and thus in the dashed position 24 "rotates Fig. 8 previously a part of the adhesive bead 34 was already severed.

Such an application of the winding device 24 with a rotatable receptacle on the clutch 15 is particularly useful when the disc 12 to be cut out has no particular obstacles to the cutting means 18. It could, for example, be a rear window of a vehicle, or even a disk on a rail vehicle, where no special obstacles occur.

However, if the geometrical conditions do not allow or only partially enable a disk to permit the above-described rotatable mounting by means of the coupling 15 on the suction plate 19 on the disk 12, then the winding device can Fig. 9 also by means of a support 32, which are opposite to the handle 22 End of the winding device is located on the body flange or frame 14 and the bead 34 along.

For support on the surface of the body flange 14 serves for this purpose the end face 33 of the support 32, which allows a guide in a direction parallel to the coil axis 72 direction. Here, the body flange 14, starting from the extended position of the cutting means 18, gradually cut through, which is represented by the dashed arrangement of the cutting means 18.
