Description

Device for the flat application of a film from a carrier tape to an object or substrate

The invention relates to a device for the flat application of a film from a carrier tape to an object or substrate with the features of the preamble of claim 1.

Numerous devices are known, in particular hand-held devices for transferring a film from a carrier belt to a substrate. For example, EP 0727378 (FIG. 7) shows a corresponding hand-held device for transferring a film of, for example, adhesive, opaque or colored material from a carrier tape 43 to a substrate 46 with a manually graspable housing, on the circumference of which an application part 45 for printing the film is indicated the substrate 46 is arranged, with the carrier tape unwinding and carrier tape winding spool 52, 49 in the housing for the carrier tape are arranged. The carrier tape runs from the carrier tape unwinding spool 52 via the applicator 45 and its tip 44 back to the carrier tape winding spool 49. A cover 31 serves as a protective device for the applicator 45. The hand H of the person using the hand-held device grips the hand-held device 50 with his thumb D from the side , the index finger Z lies on a support surface 42 which is coated with an adhesive material. The remaining fingers of the hand H rest on the side wall of the hand-held device 50 (not shown in FIG. 7). To apply the film to the substrate 46, the hand-held device 50 is placed on the substrate with the applicator 45 and its tip 44 and pulled in the direction 47 over the substrate 46. By pressing the carrier tape with the film thereon against the substrate 46 by means of the tip 44 of the application part 45, the carrier tape is transported over the surface of the substrate 46 when pulled. By means of the coupling, in particular a slip clutch, between the carrier tape unwinding and the carrier tape winding reel, the carrier tape is simultaneously wound up when unwinding from the carrier tape unwinding reel after the film has been released from the carrier tape winding reel.

In the hand-held device described above, the film is only applied when a sufficiently large contact pressure is exerted on the surface of the substrate and at the same time the hand-held device is pulled over the surface.

The object of the present invention is to parallel the film of the carrier tape without moving the device to be applied flat to the substrate to the surface of the substrate.

This object is achieved according to the invention by means of one of the devices with the features of claims 1, 15 or 19. Further advantageous embodiments result from the subclaims.

When the device is actuated, the device according to the invention transfers the film of a section of the carrier tape flatly onto the surface of a substrate or object. As a result, a movement of the device across the surface and simultaneous pressing against it is advantageously no longer necessary. The device works like a stamp, with the difference that instead of the color a film, e.g. an adhesive material or covering material such as Correction material on which the surface of the object or substrate is applied. For this purpose, the device is simply placed on the substrate or the object and pressurized by hand in the direction of the object. In the relaxed state, the application element is in its initial position.

The application element, around which the carrier tape with the film located thereon is guided, is moved in the direction of the surface of the object and, in its end position, prints the carrier tape with the film thereon against the surface of the object on which the film remains when the device is subsequently relieved .

In an advantageous embodiment, the

Device from a housing part m with an inner part slidably mounted, both the carrier tape unwinding and the inner part Carrier tape take-up reel are rotatably mounted. Either the film is applied directly from this application element against the surface of the object or substrate to be coated or a further application element is provided which removes the film from the carrier belt and transports it to the surface of the object. The latter embodiment has the advantage that damage to the carrier tape from the outside is not possible since there is no direct contact between the object and the carrier tape. In the last-mentioned embodiment, for example, the second application element is rotatably supported, the film in an upper position, in which the carrier tape is pressed in between the two application elements, is transferred from the carrier tape to the application surface of the second order element. If the device is actuated, the second application element pivots with the film located on its application surface. In the final position the applicator surface is pressed against the surface of the Ob _j ect pressurized. A longitudinal movement m in the direction of the surface advantageously takes place after the rotation of the application element. However, it is also conceivable that the order area of the order element is round, so that during the rotation of the order element and the simultaneous movement towards the surface of the object, the order element rolls off with its order area on the surface and thereby releases the film onto the surface of the object.

In a further advantageous embodiment, in which, in particular, the mechanical components of conventional hand-held devices can be used for applying films to substrates, at least the necessary components of known hand-held devices such as, for. B. the support part together with the coils and the application part pivotally mounted in a housing, the application point reaching through with its tip through an opening of the device. If the device is actuated, the carrier part is pivoted together with the application element and the film is transferred over a certain length to the surface of the object. Instead of a pivoting mechanism, a sliding mechanism is also conceivable in which the device is pulled with its application element over the surface of the object, similarly to when pivoting. As already mentioned, tested components of commercially available hand-held devices can be used in this embodiment. It is advantageous in this embodiment that no additional mechanical parts are required to transport the carrier belt. It is needed only a swiveling or sliding mechanism _j edoch relatively easily implemented. Here, for example, toothed racks and toothed wheels can be used, which are each arranged on the parts of the device which are displaceably mounted relative to one another, the application element being pivoted or displaced when the parts of the housing of the device are moved relative to one another.

In a further embodiment, the device consists only of a housing in which the coils are rotatably mounted, an application element being arranged on one side of the device in a slightly displaceable manner. The carrier tape is passed around the application element through an opening in the housing and is held taut by means of a drive mechanism which drives the coil. As soon as the device is placed on the surface of an object and a sufficiently large contact pressure is applied, it is placed on the Transfer the film on the surface of the object. When the device is lifted from the surface of the object, the carrier belt is transported further by the appropriate length of the application element by means of the drive. The transport can either be done by hand. It can be done _j edoch automatically if a corresponding transport device is provided. Here, for example, a drive device is conceivable, which is tensioned against the object by the placement and counterpressure of the device and releases its energy when the device is relaxed and rotates the take-up reel accordingly. In addition to mechanical drive options, an electric drive can also be provided, in which case sensors are to be provided in particular, which detect the loading and unloading of the device and, depending on the operating state of the device, further request the carrying strap.

In addition to an adhesive film, e.g. cover films or double-sided adhesive tapes can also advantageously be applied to an object or substrate using the aforementioned devices.

Embodiments of the device according to the invention are explained in more detail below with reference to drawings.

Show it:

Figure 3 u. 4 shows a further embodiment of the device according to the invention with a pivotably arranged application element;

Figure 7: a handheld device according to the prior art.

1 shows a cross-sectional view through a first embodiment of the device 1. The device 1 has an outer part 2 and a part 3 which is displaceably mounted in this outer housing part 2, on which the carrier tape unwinding reel 4 and the carrier tape reel spool 5 and the first application element 7 are mounted are. The carrier tape 6 is guided from the carrier tape unwinding reel 4 around the first application element 7 back to the carrier tape unwinding reel 5. The first application element 7 has an application surface 8 for evenly pressing the carrier tape 6 against the application surface 17 of the second application element 18. The first application element 7 is arranged rigidly in relation to the two coils 4 and 5 on the housing part 3. The second application element 18 is mounted on a shaft 15, on which a gear 16 is also mounted. The shaft 15 is rotatably supported in the lower region of the housing part 2. The gearwheel 16 lies in a longitudinal opening 12 of the housing part 3 and engages with its teeth in the tooth 12a of one side of the longitudinal opening 12. If the outer housing part 2 against the spring 11 downwards in the direction of object 9 is printed, the shaft 15 is moved down in the slot 12. The tooth 15a rotates the shaft 15 and with it the second application element 18 with its application surface 17. The elongated hole 12 with its toothing 12a and the gearwheel 16 with its toothing can be designed such that the shaft 15 is not rotated in a first section when the part 3 is pressed into the housing 2. This is necessary if the two order surfaces 8 and 17 of the order elements 7 and 18 are flat. It is also possible that the elongated hole 12 is not straight but curved. In this case, rotation of the shaft 15 can be started directly when the device 1 is actuated, starting with the starting position. The same problem arises shortly before the application surface 17 is printed against the surface 10. Depending on the configuration of the application surface 17, the toothing or the shape of the elongated hole 12 can be selected accordingly.

FIG. 2 shows the device m in its end position, in which the application surface 17 of the application element 18 applies the film to the surface 10 of the object 9. The opening 19 of the inner housing part 3 is penetrated by the application element 18 with its application surface 17. The front ends 14 of the inner part 3 form the support surface of the device 1 with which it can be placed on the surface 10 of the object 9.

The conveyor belt 6 can be transported further when the second application element is moved down 18 m in the direction of the surface 10 of the object 9. It is just as well possible for the carrier belt 6 to continue to move during the upward movement, that is to say from the end position into the starting position transport. It must be ensured in each case that when returning to the starting position, the application area 8 of the application element 7 (area 6c) is covered with a still coated carrier tape, so that when the application element 18 is pressed against the coated carrier tape in area 6c, the film in its area 6c is transferred to the order area 17.

In an embodiment not shown, the film is only transferred from the carrier belt to the application surface of the application element 18 when the device is actuated. This can be done in such a way that the order element slides along the order surface 8 of the order element 7 or is rolled onto it.

In an embodiment, also not shown, the second application element can be moved by means of an electromechanical drive, as a result of which it is no longer necessary to provide two housing parts which are displaceably mounted one inside the other. In this embodiment, the second application element must be stored within the one housing part.

Another embodiment of the device according to the invention is shown in FIGS. 3 and 4. In this embodiment, the device 101 consists of an outer and an inner housing part 102 and 103. In the inner housing part 103, a conventional hand-held device for transferring films to a substrate can be pivoted about an axis 105 stored. The handheld device 104 has a toothing 104a which, together with an actuating element 102a, likewise has a toothing 102b on one side thereof. The actuating element 102a is formed on the inside of the housing part 102 and engages through an opening in the housing part 103 and, by means of the toothing 102b, 104a, pivots the part 104 when the device is pressed together against the spring force of the spring 111 of the two housing parts 102 and 103. In this case, the device with its support surface 114 stands on the Surface 110 of the object 109, the object 109 generating the counterforce to the actuating force P. The part 104 is pivoted in the direction S (arrow), its application element 107 sliding with its application tip 108 over the surface 110 of the object 109. The application element 107 is made of a flexible but not too soft material, so that a sufficiently large contact pressure is generated by means of the tip 108. This ensures that the film of the carrier tape 106 is applied to the surface 110. The inner housing part 103 reaches through the opening 119 of the outer housing part 102. The application element 107 reaches with its application tip 108 through the opening of the inner housing part 103. FIG. 4 shows the device 101 in the fully compressed state. The part 104 is completely pivoted with its application element 107 and cannot be deflected any further. If the device 101 is now lifted from the surface 110 of the object 109, the two housing parts 102 and 103 are moved apart by the spring 111, which is compressed in this state, whereby the part 104 is pivoted back into its starting position via the toothing . During this backward movement, which is represented by the arrow R, the carrier belt 106 is not transported, because on the one hand either the spools are blocked in this direction or the adhesive force between non-coated ones Carrier belt 106 and the surface 110 of the object 109 are not sufficient to transport the carrier belt.

It is of course possible to replace the mechanical swivel drive with an electric swivel drive. In this case, only one part of the housing is required. In addition, the spring 111 is omitted. Likewise, instead of a pivoting mechanism, it is also possible to provide a displacement mechanism for the application element 107, the coils in particular being moved at the same time in relation to the application element.

FIGS. 5 and 6 show a further possible embodiment of the device according to the invention. The device 201 has a housing 202 which has an opening 219 through which the carrier tape 206 is guided from the carrier tape unwinding spool 204 around an application element 207 to the carrier tape winding spool 205. The application element 207 is displaceably mounted in the housing in a certain area, the direction of displacement taking place approximately parallel to the long extension of the housing body 202. For this purpose, the application element 207 is displaceably mounted in a slot 212 of the housing 202 by means of a bearing, not shown. FIG. 5 shows the device 201 in the non-actuated state which has already been placed on the surface 210 of the object 209. With this device 201, it must be ensured that there is always a carrier tape with film in front of the application element 207, so that the film is transferred directly when the device 201 is placed on a surface 210 of an object 209. The drive of the carrier tape take-up reel 205 is not shown in FIGS. 5 and 6. Only then is the carrier belt 206 transported possible if the application element 207 is not moved in the direction of the housing. For this purpose sensors or corresponding mechanical locking mechanisms can be provided. In addition, it is possible that only after the application element 207 has been fully impressed, which takes place against a spring force of a spring (not shown), the drive rotates the take-up spool 205. By pushing the application element 207 m into the housing 202, sufficient energy can be stored, for example by means of a spiral spring, which energy is released when the application element 207 is relieved.

In the above-described embodiments of the device according to the invention, the carrier belt can be transported by means of an electric drive. It is also possible to provide sensors that detect the placement of the device on an object. The signals from these sensors can be used to move the application element in the direction of the surface of the object and to apply the film. The application element can be moved by means of an electromechanical drive. The energy required for this can e.g. to supply a battery.

Triggering the device can e.g. can only be drawn after a switch that is operated manually by the person using the device is actuated.
