Definitions

  • the invention relates to a gear arrangement for driving the spool core of a take-up spool for a transfer belt through the spool core of a supply spool arranged laterally offset and radially to the take-up spool in the housing of a transfer dispenser or in an exchangeable cassette for such a with a first gear driven by the supply spool, which meshes with a second gear which serves to drive the take-up spool, the pitch circle diameter of the second gear being smaller than that of the first gear and between the spool core in one of the two spools and the associated gear a slip clutch interposed and a radially projecting washer is provided on each coil core and its side facing the other coil.
  • Transfer dispensers are widely used in the office and household sector.
  • "Transfer dispenser” is understood to mean hand-held devices for transferring a film, for example an adhesive film or a cover-up film, from a carrier tape to a base, the film-coated carrier tape being wound up on and from a supply spool within the device housing out to an order foot protruding from the device.
  • the film-coated carrier tape can be pressed against a substrate by means of the application foot, the film layer being detached from the carrier tape and transferred to the substrate in connection with the deflection of the tape at the application foot.
  • the empty carrier tape is then deflected on the support foot and returned to a take-up spool in the device housing. leads.
  • the supply reel and take-up reel as well as the application foot are often combined in a cassette.
  • the supply reel is set in rotation by the withdrawal of the carrier tape from the supply reel when the device is being used when it moves over the substrate.
  • the supply spool drives the take-up spool via a corresponding intermediate gear and with the interposition of the slip clutch, whereby care must be taken when designing the gear that the carrier tape is always kept under a desired tape tension, regardless of how large the current ⁇ winding diameter of the carrier tape on the supply reel and the Aufwickel ⁇ diameter of the carrier tape on the take-up reel.
  • the two coils can also be arranged side by side, both coaxial and slightly staggered coil arrangements in the axial direction being known.
  • the length of the device housing can be made significantly shorter than in the case of coils arranged one behind the other in one plane, the housing only having to be somewhat thicker in the area of the coil holder due to the coils lying next to one another.
  • the last-mentioned solution is used in particular when the device housing is to be designed in the form of an "elongated" housing in which a housing part is designed to be relatively small and elongated in cross section, for example in the form of an elongated cylinder or a similar shape , which makes it possible to hold the housing there like a thicker pen or a fountain pen. Only at the end of this elongated part is the enlarged and somewhat thickened housing part for receiving the two coils attached, and then when the device is held above the back of the hand of the user located (similar to the plug cap of a fountain pen when writing), that is, at a point where the comfortable grasping by the user's hand, which takes place on the elongated, thinner housing part, is not impaired.
  • the exchangeable cassette (refill cassette) has an intermediate wall section running in the longitudinal direction Des ⁇ sen one side, the supply spool and on the other side of the supply reel are rotatably mounted.
  • the spool core of the supply spool is seated on a rotary receptacle, which in turn is rotatably supported on a rotationally fixed axis of the cassette projecting from the intermediate wall section of the cassette.
  • the spool core of the supply spool is seated on the rotary mount with frictional engagement, as a result of which a frictionally acting slip clutch is formed between the two.
  • the rotary mount is in turn provided with a radially projecting annular disk which projects radially at the axial end of the coil core of the supply spool, which faces the intermediate wall section of the cassette, thereby preventing the supply band from sealing against the side when the device is in operation the intermediate wall section can slide off the supply roll.
  • a gear is integrally formed on the rotary mount, which meshes with a second, smaller gear, the central axis of which is offset in the longitudinal direction of the device from the central axis of the rotary mount and in turn engages with it.
  • the take-up spool with its spool core is attached to it in a rotationally fixed manner.
  • a radially projecting side window is also attached to the respective central axis of rotation from the outside at the respective axial free end of the reel in question, in order to avoid that when in use the carrier tape is also on this side can slip off the tape wrap.
  • the space requirement in the direction of the width of the cassette is comparatively large, since not only the coil widths have to be accommodated here, but also the width of the outer cover disks on both coils, the thickness of the two ring disks, the thickness of the intermediate belt section and the thickness of the two gear wheels on the side of the supply reel must be taken into account.
  • a comparatively large number of individual parts is required for the construction of the described arrangement of this known device.
  • the object of the invention is to propose a gear arrangement of the type mentioned at the outset for coils arranged next to one another, which can be implemented in an even smaller width than in the generic arrangement and with even fewer individual parts with a simple structure at the same time.
  • this is achieved in a generic gear arrangement by both coil cores facing one another Ring discs partially abut each other, that the first gear is designed in the form of an internal toothing attached to the spool core of the supply spool, in the interior of which the second gear lies, that the winding spool can be rotated with a central ring sleeve on a bearing shaft that is fixed to the housing or cassette sits, and that the ring sleeve is provided with a lateral shoulder which carries the second gear meshing with the first gear with an external toothing.
  • the space requirement in the direction of the width of the device or the exchangeable cassette is significantly less than in the generic device, since here only the width of the two coils and their washers must be covered.
  • Both coils or coil cores which lie against one another with their ring disks (and are thus supported against one another in the axial direction), are fastened on the cassette or housing-fixed bearing axis, which in turn projects either from a side wall of the housing or the exchangeable cassette .
  • Another space requirement in the direction of the width (axial direction of the coils) is not necessary.
  • the gear arrangement according to the invention has a remarkably small number of individual parts to be assembled, that is to say two coil cores which (for example, in one piece) are provided with the radially projecting ring disks, and also the slip clutch (which is in one piece with the lateral attachment of its ring sleeve and the toothing of the second gearwheel attached to it is formed) and finally only the bearing shaft which is fixed to the housing or cassette and the associated side wall section of the cassette or the housing.
  • the significantly reduced number of individual parts required compared to the generic arrangement simplifies the overall construction and considerably simplifies and speeds up the overall assembly.
  • the two coil cores of the two coils with their radially projecting annular disks partially abut one another in the invention, the two coil cores can be axially fixed to one another without the need to use an intermediate wall, so that when one coil core with its other axial end is supported in a suitable form on a side wall of the housing or the exchangeable cassette, only an axial fixation of the free end of the central ring sleeve, which is connected to the other coil, is required on the bearing axis in order to enclose the entire arrangement. to be fixed to the cassette.
  • the use of a gear transmission by means of an internal toothing creates the possibility of arranging the two gearwheels in the plane of the supply reel (namely within the inner region enclosed by their coil core), so that no additional space is required for this Gear transmission is required.
  • Another advantage of the invention is that the intermeshing teeth are without load in the direction of force.
  • the slip clutch between the spool core of the supply spool and the inner toothing must be suitably provided, for example by a corresponding frictional fit between the coil core and a rotary mount which has the internal toothing.

  • the slip clutch can be designed in any suitable form.
  • the slip clutch has a plurality of spring tongues extending from the central ring sleeve, which bear against the inner diameter of the coil core of the take-up spool and carry it, that is to say a rotary mount for the latter form.
  • This allows the slipping clutch to function even longer than in the case in which the slipping clutch consists only of a purely frictional fit of the coil core on a corresponding rotary mount, such as in the generic gear arrangement, which occurs even when the smallest occurs the friction of wear and tear phenomena immediately leads to a noticeable influence on the frictional torque and thus to a change in the properties of the slip clutch.
  • the internal toothing can be provided in any suitable form and can be connected to the coil core of the supply coil.
  • the internal toothing is very particularly preferably formed in one piece on the inner circumference of the coil core of the supply coil, which results in only one component for both, which is preferably made of plastic and e.g. can be made from injection molding.
  • the outer diameters of the ring disks of both coil cores are of the same size. It can thereby be achieved that the space, which is predetermined by the outer diameter of the supply reel winding determined by the required meter output band, can also be fully used on the winding side, the core of the winding reel being designed so that the outer diameter of the full empty reel corresponds to that of the full supply roll and thereby an advantageous low winding height (number of layers of the winding tape) is achieved.
  • a further advantageous embodiment of the invention also consists in that the coil core of the supply coil with its axial end face facing away from the ring disk is supported in the axial direction on the side wall of the housing or a side wall of the exchangeable cassette and on its inner circumference at one or more support points, which is or are offset from the point of engagement of the internal toothing with the second gear, fixed to the housing or is supported in a cassette-proof manner.
  • the spool core of the supply spool being supported radially towards its axis of rotation at a point radially opposite the point of engagement of its internal toothing with the second gearwheel by a support fastened to the side wall of the housing or the cassette, so that here two mutually opposing heel points are created, namely on the one hand this support part and on the other hand the point of engagement between the internal toothing and the second gear.

  • the support part is particularly preferably formed in one piece with a side wall of the housing or the cassette, so that a one-piece component is also produced in this respect.
  • the arched support part can also be manufactured as a separate part and then connected in a suitable form to the side wall of the housing or the cassette, for example by gluing or the like
  • the slip clutch in the gear arrangement according to the invention is provided with a plurality of spring webs extending from the central ring sleeve, it is particularly advantageous if, in addition to the spring webs, radially extending support webs are also provided for additional support of the inner diameter of the take-up spool, in such a way that they run into the spring bars with their radially inner ends.
  • the radial support webs are preferably provided at their free ends with support shoes, each of which has on its surface a contact surface which is adapted in shape to the inner surface of the spool core of the take-up spool. It is very particularly advantageous if the support shoes have a bevel which slopes radially towards the second gear wheel over their axial width, ie their width in the axial direction of the take-up reel, which facilitates the introduction of this slip clutch, in which the Spring bars with the central ring sleeve and their lateral attachment with the external toothing are formed as one component, particularly easily and quickly from the outside of the coil core of the winding reel in its inner diameter. This creates a slight taper in the direction of insertion, which significantly simplifies assembly.
  • An advantageous further development of the invention also consists in that on the support shoes on their axial ends, which are on the side facing away from the second gear wheel, there are stops which project radially beyond the support surface and axially against one correspondingly on the inner circumference of the coils ⁇ core of the take-up spool provided ring shoulder and fix this spool guide and thus the take-up spool axially relative to the central ring sleeve.

  • the invention creates a surprisingly simple, very compact gear arrangement which requires space in the direction of the width of the housing or the exchangeable cassette, which is particularly small.
  • the arrangement according to the invention consists of a particularly small number of individual parts which can be assembled easily and quickly, are simple to manufacture and thus permit particularly inexpensive manufacture of the exchangeable cassette or of the entire transfer dispenser.
