Description

Apparatus for transferring a film to a substrate

The present invention relates to an apparatus for transferring a film to a substrate. Such devices are preferably used in the office, such as for transferring an adhesive, correction or marking film from a carrier tape e.g. used on a paper surface by means of a so-called hand rolling device. Such a device usually has a supply and a take-up reel for the carrier tape, wherein the carrier tape is guided to press its film side starting from the supply reel via an applicator element and back to the take-up reel.

A device of the aforementioned type for applying an adhesive or correction film to a substrate is known, for example, from EP 0 313 719 B1. The interchangeable cassette described there for a generic hand rolling device comprises a supply reel, on which the unused carrier tape is rolled up with film, a take-up reel on which the used carrier tape wound without film and an outstanding from the manual rolling applicator to the actual film application to the substrate. The carrier tape is unwound from the supply spool and passed over the applicator, which applies by pressing film on the substrate. Specifically, the applicator is pulled with the applicator under appropriate contact pressure in the longitudinal direction of the carrier tape over the substrate, wherein continuously carrier tape is unwound from the supply reel. Behind the application device, the carrier tape, without film, returned to the take-up reel and wound up on this. The removable cassette is arranged in the ready state in the housing of a hand rolling device and basically allows easy replacement of a spent cassette, in which already the entire film is transferred, or the supply reel is completely unwound. By virtue of the applicator device protruding from the manual rolling device and guiding the carrier tape, the film and also the carrier tape itself are not sufficiently protected from external influences. In particular, when not in use of the hand-rolling device, the applicator may suffer damage due to external influences or improper storage, which can lead to malfunction when applying the film through the hand-rolling device to a total failure of the device. In addition, the guided around the applicator carrier tape can tear, resulting in a loss of function of the entire hand-rolling device. Another disadvantage is the contamination of the film in the area of the applicator when not in use by dirt or dust, so that when restarting the manual rolling a soiled film is transferred, which may not be sufficiently liable or even destroyed the substrate by the impurities applied.

Another device of the type mentioned for applying a correction tape to a substrate is known from DE 196 11 440 B4. The correction tape dispenser disclosed here includes Housing on, and a supply spool and a pickup coil for the correction tape, and a Umlenkübertragungskopf around which the correction tape is guided, wherein the Umlenkübertragungskopf protrudes from the housing. To protect the transfer head when not in use the correction tape dispenser a slidably held cover is provided on the housing, which can be moved in the direction Umlenkübertragungskopf to protect it from external influences. Even with this correction tape dispenser no adequate protection is ensured when not in use against external influences. Although a cover is provided which partially surrounds the deflection transfer head when the correction tape dispenser is not in use, sufficient protection is not guaranteed by the cover. In drawers or briefcases in which such donors are stored when not in use, the cover can be easily moved by other office utensils, so that the deflection transfer head is exposed and destruction and / or contamination is inevitable. Also, in the event of a fall of the dispenser with the deflection transfer head, the cover is simply displaced in the direction of the housing so that here too the deflection transfer head is exposed and neither is secured against contamination nor destruction. In most cases, resuming work with the donor is not possible, so it must be disposed of.

JP-A-11-170775A discloses a device for applying a film to a substrate by means of an applicator foot having a housing with which the applicator foot can be covered.

In view of this, the object of the present invention is to provide a generic improved apparatus for transferring a film to a substrate, which ensures reliable protection of the film-transferring components when not in use.

This object is achieved by a device for transferring a film onto a substrate having a housing and a transmission unit connected to the housing with a discharge end for applying the film to the substrate, wherein the transfer unit is designed rotatable relative to the housing about an axis of rotation to between an order position and a rest position of the transmission device to change and being provided on the axis of rotation of the transmission unit detachable connection means between the transmission unit and the housing to make the transmission unit interchangeable.

Preferably, the transfer unit is rotatable relative to the housing such that the delivery end of the transfer unit in the order position points away from the overall arrangement and provides a part of the outer contour of the overall arrangement. To provide the rest position, the transfer unit is preferably rotated about the axis such that the delivery end of the transfer unit is no longer away from the overall assembly. By using such a rotatable transfer unit relative to the housing, a device can be provided with which in a job position of the transfer unit, a transfer of a film to a substrate is readily possible. After completion of the transfer of the film, the Users rotate the transmission unit about the axis to a rest position of the transmission unit, in which in particular the discharge end of the transfer unit is protected from external influences and thus from contamination and destruction. In a preferred embodiment, the device is designed such that in the rest position of the transmission unit, the outer contour of the device is designed such that upon a fall of the device on a substantially flat surface, the discharge end of the transfer unit can not hit the surface. Preferably, the housing is designed as a handle, which preferably serves as an extension of the transfer unit in the order position and provides the user with a secure and firm hold when transferring the film to a substrate. In this case, the handle may have anti-slip agents, such as silicone or rubber inserts or recessed grips.

The releasable connection means between the transfer unit and the housing, allow a replacement of the transfer unit. These releasable connection means are provided on the axis of rotation. By providing a releasable connection by means of the releasable connection means, a device can be provided, wherein the housing can be maintained in the event of a worn transmission unit. It only needs the transmission unit separated from the housing by means of the releasable connection means and replaced by a new one. In this way, a resource-saving device is provided which can be refilled by corresponding refill transfer units. The releasable connection means may be designed in particular as screw or plug connections, wherein a fixed axis of rotation for the transmission unit is provided by the releasable connection means by means of a dome or pin. Another possibility is the provision of snap elements and corresponding receptacles of the transmission unit, so that the transmission unit only has to be snapped in, wherein the snap connection must be configured such that a rotation is possible at any time.

The discharge end of the transfer unit for applying the film to a substrate may include any shapes. In particular, applicator heads, which may be spring-mounted or oscillating, are conceivable. Furthermore, rollers for deflecting the carrier tape and transferring the film from a carrier tape to the substrate are conceivable. In particular, adhesive films, correction films or even marking films for highlighting text passages may be conceivable as films. A first advantageous embodiment of the device provides that the housing encloses the transmission unit at least partially. The provision of such a housing has the advantage that in the areas in which the housing encloses the transmission unit, lower material thicknesses can be used on the housing, since the strength is provided essentially by the housing. In this way, a low cost device is provided. In addition, a housing can be used, wherein the region of the axis of rotation of the transmission unit is enclosed by the housing. This is particularly useful to avoid contamination of the axis of rotation or to protect the user from jamming during rotation of the transmission unit relative to the housing. A functional improvement in the handling of the device results from the fact that the housing has a cavity in which the transmission unit can be accommodated in the rest position at least partially. Through the use of such a housing, a secure protection for the transmission unit and in particular the delivery end of the transmission unit can be provided in the rest position, so that at any time the recording of work after activation of the system is possible. Preferably, the size of the cavity substantially corresponds to the outer dimensions of the transmission unit, so that when rotated in rest position transmission unit it is enclosed by the outer contour of the housing, whereby a large protection from external influences, damage by third things or falls can be effectively avoided.

Another advantage is the use of a transmission unit, which protrude in order position at least partially out of the housing. In particular, a protruding of an attack area, which is provided on the transmission unit, as well as the delivery end of the transmission unit is conceivable. This has the advantage that the user can safely guide the transfer unit during the transfer of the film to a substrate. Unintentional rotation of the transmission unit relative to the housing can be avoided. To further improve the work with the device, slipping elements can be provided on the projecting part of the transfer unit, giving the user good attack possibilities. In particular, silicone or rubber inserts are conceivable or grip recesses, as well as transversely to the direction of movement extending projections or depressions that unfold a slip inhibiting effect in the user.

A further advantage is the use of a transfer unit which comprises an application strip for transferring the film to the substrate, wherein the application strip is arranged substantially parallel to the axis of rotation of the transfer unit for rotation of the transfer unit relative to the housing. An order bar arranged in this way enables the user to be provided with a tool which is in use immediately after the rotation. When force is applied to the device during film application, a force is exerted on the components providing the axis of rotation. Due to the parallel arrangement of the application strip and the axis of rotation, the applied force is evenly distributed over the axis of rotation. Tilting the components providing the axis of rotation and possible destruction of the rotary function can thus be avoided.

Another advantage is the use of a transfer unit with a rotatable supply reel, with a coated with the film to be transferred carrier tape wherein the axis of rotation of the transfer unit for rotation relative to the housing corresponds to the axis of rotation of the supply reel. Through the use of coaxial axes of rotation, a device with particularly small external dimensions can be provided. Another advantage is the use of a housing with one or more stop areas, which limit the rotation of the transfer unit. The use of such attacks has the advantage that the user during the rotation of the transmission unit relative to the housing boundary points are given, which correspond to a preposition resting and / or order position. The user is thus provided with an easy-to-use device, the transfer unit preferably being able to be rotated between two stops, one stop representing the rest position of the transfer device and the second stop representing the order position of the transfer device. Malfunctions with such a device are excluded even for first-time users.

Another advantage is the use of a transmission unit which has one or more fixing elements which fix the transmission unit in predetermined angular positions relative to the housing. In this case, in particular suitable snap mechanisms by, for example, projections on the surface of the transfer unit are conceivable which determine the transfer unit in the predetermined angular position relative to the housing, so that a rotatability is possible only with the overcoming of an obstacle for the user. Through the use of such a transfer unit, a secure device is provided, wherein the transfer unit remains in the predetermined angular position, preferably in the rest and / or the order position. An automatic rotation of the transmission device relative to the housing is avoided, so that a secure film order on the transmission unit for the user is possible.

A useful further development of the design with ornamental elements is the use of a housing with corresponding receptacles to the fixing elements of the transfer unit. In this way, the fixation of the transfer unit in a predetermined angular position is supported relative to the housing and the safety in the application for the user can be further improved. Preferably, the fixing elements and the corresponding components of the housing are designed such that the user is informed by an audible sound, for example when snapping a projection of the transfer unit into a suitable receptacle of the housing that a predetermined angular position, for example, the rest and / or order position is reached.

Further useful details of the invention will become apparent from the illustrated in the drawings embodiments, which are explained in more detail below.

An apparatus shown in the figures is used for transferring a film from a carrier tape to a substrate. In this case, the detached from the carrier tape film, for example, transferred to a sheet of paper to cover the characters thereon, for example, with a correction film. Instead of the correction film, it is also possible to apply an adhesive film or a luminous colored strip to the substrate in order to provide it with adhesive for gluing or to highlight or emphasize text passages located thereon. Of course, in addition to the film order, a pigment composite contract or the order of a pigment composite is possible. Including a partial application of adhesive, for example, is also possible. In this case, the carrier tape is not provided areally with an adhesive film, but only partial sections of any size and shape. In this way, for example, adhesive can be saved.

An inventive device for transferring a film to a substrate is realized in the present embodiment as a correction roller. The device initially has a housing 10. The housing 10 is designed as a handle element with an ergonomic shape to ensure safe guidance by the user and has a handle portion 13. This can be provided with anti-slip agents, such as silicone inserts. A transmission unit 100 is rotatably connected about an axis of rotation 101 to the housing 10 via connecting elements 11. The transfer unit 101 has an application element 102 for transferring a correction film to a substrate. To transfer the film, the user exerts a force on the transfer unit 100 and thus on the applicator element 102 in the direction of the substrate. For this purpose, the transmission unit 100 handle means 105 are provided which allow the user a good attack position and prevent slipping. In addition, the housing 10 provides a stop area 15, on which the transmission unit 100 can be supported on the housing 10. The order of the correction film is carried out by simultaneously pulling the device in the direction of the handle portion 13 and force towards the substrate.

FIG. 2 shows an exploded view of the device according to the invention from FIG. 1. The in the assembled state of the device partially covering the transmission unit 100 housing 10 has in the region of the cover on both sides openings on which matching fasteners 11 can be used. These connecting elements 11 are designed such that they snap into the openings of the housing 10 and partially to the one Cavity 12 bounding inner surfaces of the housing 10 protrude. For mounting the device, the transmission unit 100 is pushed in the direction of the housing 10 such that the protruding into the cavity 12 parts of the connecting elements 11 are guided into a channel 110 of the transmission unit 100. Preferably, the transmission unit 100 has such a channel 110 on both sides. Preferably, the connecting elements 11 during insertion of the transmission unit 100 in the cavity 12 of the housing 10 when reaching the channels 110 is slightly pushed by the transfer unit 100 from the housing 10, but the snap connections between the connecting elements 11 and the housing 10 are not solved thereby. Further insertion of the transfer unit 100 into the cavity 12 of the housing 10 causes engagement of the pushed-away connecting elements 11 in a recess 109 of the transfer unit 100. Such a recess 109 is preferably provided on both sides of the transfer unit 100. Preferably, the recess 109 is designed such that no force is exerted on the connecting elements 1 1, which is able to push out the connecting elements 11 from the openings of the housing 10. By the connection of the housing 10 with the transmission unit 100 by means of the connecting elements 11, a refillable correction roller is provided in the present embodiment. For this purpose, the user can maintain the housing 10, in the present case the grip element with the grip region 13, as well as the connecting elements 11. The transmission unit 100 can be exchanged at any time in a simple manner via said connection technology. By the connecting elements 11, which engage in the recess 109 of the transmission unit 100, also a rotatable connection between the housing 10 and the transmission unit 100 is provided to. In this case, the transmission unit 100 in the mounted state about the rotation axis 101 relative to the housing

10 are twisted. Of course, other connection possibilities between the transmission unit 100 and the housing 10 are conceivable. For example, a connector

11 with a mandrel conceivable, which is inserted through a lateral opening of the housing 10 in an opening 108 of the transfer unit 100. In this way, also a rotatable connection between the transmission unit 100 and the housing 10 can be provided. Preferably, the opening 108 in the transmission unit is concentric with the axis of rotation 101.

FIG. 3 shows a sectional side view of the device according to the invention from FIG. 1 in the mounted state. The transfer unit 100 has a rotatably mounted supply spool 111. The supply reel 111 serves to receive the carrier tape 114 coated with a film 113. To receive the carrier tape 114 after the film 113 has been transferred to a substrate, the transfer unit 100 has a rotatably mounted take-up reel 112. The synchronization of both coils 111, 112 is achieved by means of a known to those skilled, unspecified slip clutch. The carrier tape 114 provided with the film 113 is led out from the supply reel 111 through an opening at the discharge end of the transfer device 100 and deflected by an applicator element 102. The transfer of the film 113 from the carrier tape 1 14 to the substrate via the applicator 102 by means of an application bar 103. The leadership of the carrier tape 1 14 takes place by means of two Bandführungswangen 115. After deflecting is the now film-free carrier tape 1 14 again fed back through the opening in the interior of the transfer unit 100 and received by the take-up reel 112. The axis of rotation of the supply reel 11 of the transfer unit 100 corresponds to the axis of rotation 101 around which the transfer unit 100 can be rotated relative to the housing 10. In the present embodiment, a device is shown in order position. That is, in this position of the transfer unit 100 relative to the housing 10, the user can apply a film to a substrate. For the order, the housing 10 has a stop area 15, on which the housing of the transfer unit 100 is supported during the order. In order to fix the transfer unit 100 in the order position, a first projection 106 is provided on the transfer unit 100, which engages in a recess 14 of the housing 10. The user can rotate the transmission unit 100 about the axis of rotation 101 in such a way that the transmission unit 100 is received by the cavity 12 of the housing 10. In this case, a rotation of the transmission unit 100 is provided relative to the housing 10 substantially by 180 °. In order to keep the transmission unit 100 in the rest position, a second projection 107 is provided, which can be brought into engagement with the recess 14 of the housing 10.

FIG. 4 shows a sectional side view of the device according to the invention from FIG. 1, with the transmission unit 100 in the rest position. For this purpose, the transmission unit 100 has been rotated about the axis of rotation 101 relative to the housing 10 so that it is located substantially within the cavity 12 of the housing 10 and surrounded by the cavity 12 limiting side surfaces of the housing 10. Both the applicator element 102 of the transfer unit 100 and the film 113 afflicted side of the carrier tape 114 are surrounded by the cavity 12 delimiting the inner surfaces of the housing 10 and thereby protected from external influences, such as destruction or contamination. In order to ensure a secure reception of the transmission unit 100 in the rest position in the cavity 12, the second projection 107 of the transmission unit 100 is in engagement with the recess 14 of the housing 10th

FIG. 5 shows a side view of the device from FIG. 1, with the transmission unit 100 in the rest position. It can be seen that the sensitive components, in particular the applicator element with the application strip of the transfer unit 100 and the film-carrying carrier strip, do not protrude from the outer contour of the side surfaces of the housing 10. In this position of the transfer unit 100 relative to the housing 10, a secure storage possibility of the device is ensured without damaging or polluting the externally sensitive components. Even a fall of the device, for example from a desk or from a bag to a hard surface, wherein the transfer unit 100 is in rest position, does not affect the function of transferring a film to a substrate, since a secure storage of the transfer unit 100 in the cavity of Housing 10 is provided. A recording of the work is readily at any time by rotation of the transfer unit 100 relative to the housing 10 from the rest position in the Order position possible. For this purpose, a recess 104 is provided on the transmission unit 100. The user is thus provided with an attack area by which he can easily rotate the transfer unit 100 with respect to the housing 10. In addition, the size of the cavity of the housing 10 can be selected such that the user sufficient space is provided that he can turn the transfer unit 100 in the direction of order position on the applicator.
