Definitions

  • the invention relates to a device for transferring a film present on one side of a film strip from this film strip to a carrier, with a housing in which an unwinding spool, a winding spool coaxial therewith for the film strip and an application device at least partially protruding from the housing are provided, wherein the film strip carrying the film is unwound from the unwinding spool, guided over the application device and wound onto the winding spool connected via a friction clutch.
  • DE 37 36 367 C shows a hand-held device for transferring a film from a carrier film to a substrate, in which the band-shaped carrier film is unwound from a first spool, is passed over an application device where the film is placed on a substrate, for example paper, is transmitted, and then rewound on a second spool.
  • the two coils are arranged separately from one another, and the tape level of the carrier film remains unchanged during the entire process.
  • the device as a handheld device is relatively unwieldy, since it has to be large due to the two coils arranged one behind the other and also has to be operated in a relatively uncomfortable hand position, with the hand hindering the view of the transmission location from above with the back of the hand.
  • EP 368 070 A also describes a hand-held device in which the axes of the take-up and take-up reel are inclined at an angle to one another.
  • a kind of tooth coupling acts between the coil hubs, the one teeth being attached to separate elastic coupling pawls.
  • the clutch implemented in this way can slip with a correspondingly high breakaway torque by the teeth sliding over one another under the inward springs of the clutch pawls.
  • this training is extremely complex and costly to manufacture, and the slipping moment can only be controlled with little accuracy.
  • EP 377 085 A discloses a device for applying an adhesive film with a coaxial arrangement of the winding and unwinding spool, a friction or slip clutch also being effective between the two spools.
  • this is a (in particular magnetic) disc clutch, axially directed surfaces abutting one another and possibly slipping relative to one another.
  • This device is also relatively imprecise and coarse in terms of torque control, so that there are band breaks.
  • the unwinding reel has a smaller reel diameter or reel hub diameter compared to the reel spool, so that at the same speed of the two reels a higher peripheral speed and thus tape speed is brought about on the reel spool. This is where the friction clutch comes into operation, which has to slip accordingly in order to achieve the same belt speeds on the unwinding reel as on the winding reel.
  • the friction or slip clutch is to be dimensioned in an extremely narrow range, on the one hand both at the beginning of the use of the device when there is still a full tape reel on the unwinding spool, and on the winding spool only one or two layers of the film tape are included, as well as towards the end of use, when almost the entire film strip is wound onto the take-up reel, so that there the tape roll has a correspondingly larger diameter compared to the tape roll on the take-up spool to ensure adequate tension in the film strip , so that the tape is neither guided too loosely (and in particular unwound into a loop outside the device) nor tensioned too much (in which case it would tear).
  • the aim of the invention is to provide a device of the type mentioned at the outset, which is compact and also allows an exchangeable cassette design for the coils, which is handy and which allows convenient control of the transmission process during use; Above all, the invention also aims to enable precise control of the torque transmission or determination of the breakaway torque, so as to always keep the film strip under an adequate tension without it tearing and without a loose loop being formed can.
  • the inventive device of the type mentioned is characterized in that the contact areas of the friction clutch with the unwinding spool and the contact areas of the friction clutch with the winding spool are arranged radially offset from one another.
  • the unwinding and winding spools with hub parts can be inserted one into the other.
  • a compact coil unit in particular in an exchangeable cassette version, can be obtained, which can be inserted into the housing of the device in the preassembled state.
  • the radially acting friction clutch can be accommodated not only in a space-saving manner, so that a low overall height of the device can be achieved, but also can be dimensioned precisely with regard to the torque setting, so that a reliable function of the device is obtained with an always adequately tensioned film strip. Tear of the film strip is prevented as well as loose loops outside the housing of the device.
  • the friction clutch for example, sleeve-like coupling parts, which may also be stepped, could be used, but preferably the friction clutch is simply in the form of a ring, i.e. O-ring, especially made of plastic.
  • O-ring In order to obtain additional options for dimensioning the torque transmission in the narrow range mentioned by a special shape with a spring action, the O-ring can be shaped wavy.
  • the O-ring has resilient friction engagement teeth projecting axially from an annular body.
  • the friction engagement teeth are shaped with radially directed brake knobs.
  • the ring is made of polyoxymethylene.
  • the ring is in a snap fit, e.g. with the help of an annular bead on which a coil is held.
  • FIG. 1 shows a view of a device according to the invention with the upper housing cover removed;
  • 3a shows a plan view of an unwinding spool
  • FIG. 3a shows an axial section through this unwinding reel according to line B-B in Figure 3a;
  • 4a shows a plan view of a take-up reel
  • FIG. 5 shows a cross section of a friction clutch in the form of a corrugated O-ring
  • FIG. 6 shows a further embodiment of a ring friction clutch in front view, partially in axial section
  • FIGS. 6 and 7 shows a half view of an assembly of a winding spool and an unwinding spool with the friction clutch according to FIGS. 6 and 7 in axial section;
  • FIG. 9 shows a modified embodiment of a ring friction clutch in a diagram.
  • FIG. 1 shows a device for transferring a film 2 present on one side on a film strip 1 from the latter onto a carrier, the upper housing part being lifted off;
  • Figure 2 shows a section along the line A-A in Figure 1, with the upper housing part 3a is attached.
  • the film strip 1 is rolled up on an unwinding spool 4, one side of this film strip 1 being covered with the film 2, which comprises, for example, a correction substrate which is applied in dry form over a text to be corrected and can then be overwritten.
  • the film strip 1 can also be covered with an adhesive or dye film. 1 shows an unwinding spool 4 that is almost completely unrolled, the film strip 1 being guided over a first deflection guide 6a and being guided from there around an application device 7; the film strip 1 is thereby rotated about its longitudinal axis by 90 ".
  • the film strip 1 can be sharply deflected on a front edge of the applicator device 7, which is designed as a tear-off edge 10 and protrudes from the housing 3, the film 2 on a carrier how paper or the like can be transferred, as indicated by dashed lines in Fig.1.
  • the film strip 1 is guided around a second deflection guide 6b, again being rotated through 90 °, and then guided onto a take-up reel 5 and rolled up thereon.
  • the application device 7 is tongue-shaped and is fixed at the end lying inside the housing 3 on both sides of the lower part 3b thereof, this fixing possibly being detachable at least on one side, as will be described further below.
  • the end of the application device 7 protruding from the housing 3 has two parallel, approximately triangular side boundaries 15, which on the one hand are intended to prevent the film strip 1 from slipping sideways and on the other hand, as can be seen in particular from FIG Represent the device while pulling the film 2 from the film strip 1 and transferring the film 2 onto the support base. Further guides can also be provided on the application device 7, as shown in FIGS. 1 and 2 and designed as pin-shaped projections 16.
  • the application device 7 will yield somewhat when it is guided over the carrier, for example paper, which on the one hand allows the contact pressure on the carrier to be controlled and on the other hand provides a somewhat wider contact surface.
  • the tear-off edge 10 is designed as a rounded edge with a small radius in order to enable the film 2 to be detached from the film strip 1 in a defined manner. This is just for applying a correction film to one defective text area so that it is possible to cover only the actually defective text area.
  • the slight rounding of the edge also has the effect that when the film 2 is applied to the carrier, on the one hand this carrier, which may be thin copy paper, is not damaged, and on the other hand there is no risk of the film strip 1 tearing during this application process.
  • the unwinding spool 4 and the winding spool 5 are, as can be seen from FIG. 2, mounted coaxially one above the other on a housing-fixed axis 8; the unwinding process of the film strip 1 from the unwinding spool 4 is effected by pulling the film strip 1 when the film 2 is applied to the carrier.
  • the winding of the film strip 1 on the take-up spool 5 is achieved due to the friction via the coupling surfaces provided on the two spools 4, 5 and engaging with a friction clutch by the movement of the take-up spool 4.
  • the friction clutch is designed as a friction ring, as an O-ring 9.
  • the Fig.1 which shows the device according to the invention - here designed as a hand-held device for applying a correction film - compared to the natural size in a slight enlargement, makes it clear that the handling of the device in two ways, both due to the space-saving arrangement of unwinding and Take-up reel 4, 5, and also because of the guidance of the film strip 1 with twisting by 90 °, is ergonomically convenient and simplifies the checking of the application of the film 2 on the carrier for the user, since this is clearly visible.
  • the device with its compact coil arrangement lies comfortably in the hand during the application process.
  • a recess 17 is provided on the upper housing part 3b (see FIG. 2), into which a finger, for example the thumb of the user, can be placed.
  • FIGS. 3a and 3b show an unwinding spool 4 in plan view or in section along the line BB in Fig.3a.
  • the unwinding spool 4 is designed as a wheel-shaped disk 18 provided with spokes with a central sleeve (hub) 19 provided for receiving the axis 8.
  • the middle sleeve 19 protrudes on both sides beyond the disk 18, the film strip 1 initially being wound on the upper sleeve part 19a, with reference to the section shown in FIG. 2, while the lower sleeve part 19b is shown in FIG a correspondingly shaped recess 20 engages in the take-up reel 5 (see FIGS.
  • An all-round projection 21 on the lower sleeve part 19b of the unwinding reel 4 and the outer wall surface 22 of this lower sleeve part 19b together with the inner wall surface 23 of a cylinder 25 carrying the supporting surface 24 for the film strip 1 to be wound on the winding reel 5 form a kind Coupling housing for receiving the O-ring 9 acting as a friction or slip clutch (Fig. 2, Fig. 5).
  • Locking notches 29, which are provided on the upper edge of the middle sleeve 19 of the supply reel 4 and which cooperate with corresponding projections 30 (see FIG. 2) provided on the upper housing part 3b, act as a rewind stop for film strip 1 that has already been unwound.
  • Other known means as well could be provided, such as locking members that snap into teeth provided on the supply reel 4, for example (not shown).
  • the take-up spool 5 is designed similarly to the take-up spool 4, and both spools 4, 5 are light and yet stable, partly due to the skeletal shape of the support surface 24 of the take-up spool 5.
  • the torque can of course also be transmitted in a different way due to friction; for example, radially acting coupling surfaces on the winding or unwinding spool can also be in direct contact with one another, it being possible for these contact surfaces to be present on the spool hubs. Friction-increasing intermediate layers or friction-increasing knobs or grooves can also be provided.
  • the O-ring 9 'shown in FIG. 5 has a corrugated cross-section, which, in contrast to a purely ring-shaped O-ring 9 (which - as can be seen from the above - could also be used), makes this O-ring 9' has isolated axial support areas which are spaced apart from one another in the circumferential direction.
  • the contact areas 13 effective with the unwinding spool 4 are in frictional engagement on the outer wall surface 22 serving as the coupling surface with respect to the unwinding spool 5, namely with the inner wall surface 23 serving as the coupling surface Contact areas 14 offset at an angle.
  • the free spaces in between are also of different sizes.
  • the contact pressure of the O-ring 9 ' is determined not only by the hardness of the ring material (for example plastic, approx. 40 Shore), as in the case of a purely circular O-ring 9, but also by the shape, ie the number and depth the "waves".
  • This change of contact surface and free space - and also offset for the coupling surfaces against each other - makes it possible to adjust the coupling very precisely, for example, to the length, thickness and tension of the film strip 1, to the compactness of the spools 4, 5 and to the desired use of the device.
  • the device allows, precisely because of the compact arrangement of the two coils 4, 5, to form them as an exchangeable cassette, and after removing the upper housing part 3b, the two coils 4, 5, which - as can be seen particularly well from FIG can be placed on the housing-fixed axis 8 without the need for an adjustment.
  • the film strip 1 can be placed around the snapping 26 (in FIG. 1), if necessary, around it and around the deflection guides 6a, 6b, after which the application device 7 is snapped back into the snapping 26.
  • the film strip 1 can then be pulled loop-free by rotating the take-up spool 5 over an optionally provided knurled ring.
  • a viewing window 28 (FIG. 2) can be provided on the housing, in particular on the upper housing part 3b, which allows the user to control the amount of the film strip 1 which has not yet been unwound and is therefore still available.
  • the friction clutch shown in FIGS. 6 to 8 in the form of a modified O-ring 9 " consists of an annular body 31, on which friction engagement teeth 32 projecting in the axial direction are formed, which have brake knobs 33 on their inside.
  • the brake knobs 33 are in this case, for example, formed as elevations approximately in the shape of a segment of a circle, as can be seen from FIG. 6 and the combination of the take-up spool 5 with the take-off spool 4 and the O-ring 9 "arranged in between according to FIG.
