Definitions

  • the subject matter of the invention is a film dispenser with a system for the secure, rotatable mounting of a film roll or a sheetlike structure wound onto a core in a dispenser housing.
  • Cling film, aluminum foil, and parchment paper are examples of sheets that are commonly wound onto a core, which core typically includes a core sleeve.
  • Such rolls of film are stored in dispenser housings, which generally include a removal opening for pulling out an end section of the wound film and means for separating such end sections from the film supply wound onto the core.
  • foil and “foil roll” are used synonymously for any fabric or roll of fabric, unless otherwise noted.
  • Foil rolls for household purposes are widely stored in folding boxes which include, for example, a jagged tear-off edge as a separating means.
  • the folding boxes serve as a storage container and as a dispenser housing at the same time.
  • the folding boxes are one-way containers be disposed of as soon as the foil stock is completely used up.
  • Foil rolls for commercial purposes are comparatively large. They comprise foil strips wound onto a core, the length of which can be, for example, of the order of about 100 m to about 600 m, and the width of which is typically in the range of about 30 cm to 60 cm and is in particular 45 cm or 30 cm. Such film rolls are preferably stored at the place of use in stable, refillable dispenser housings.
  • a foil dispenser which comprises a housing made of metal and is designed to accommodate two rolls of foil in a space-saving manner.
  • the foil rolls each comprise a core sleeve and a foil strip wound onto it.
  • the core sleeve protrudes axially on both sides of the coiled film strip.
  • the end sections of the core sleeve are rotatably mounted on roller holders in the housing.
  • the roller holders are bearing plates which protrude upwards on the housing floor and have recesses which are open towards the upper end face and are designed to receive one end section of the respective core sleeve.
  • Edge areas of the bearing plates which delimit the recesses on the side of a removal opening of the housing, act as retaining elements.
  • the end portions of the respective core sleeve are pulled against the corresponding retaining elements. Together with the force of gravity acting on the film roll, this has the effect that the ends of the core sleeve remain in the recesses of the bearing plates even when film sections are pulled out through the removal opening. It is implicitly assumed that the film roll is sufficiently heavy.
  • EP3453659A1 In order to prevent the ends of the core sleeve of a smaller, lighter-weight film roll stored in the front area of the housing from jumping out of the recesses, especially in the case of an unfavorable pulling angle, it is suggested EP3453659A1 before forming a kink or a curvature in the corresponding retaining elements. Even in such embodiments, a sufficiently high tensile force on the end section of the film strip can cause film rolls with relatively low weight in particular to be lifted against the acting force of gravity and/or rolled upwards along retaining elements and jump out of the recesses. To prevent this, beats EP3453659A1 as an alternative measure, load the respective roll of film with the weight of a hold-down device pivotably mounted in the housing.
  • An object of the present invention is to provide a film dispenser with a system for securely rotatably supporting a roll of film in a dispenser housing create, wherein the film roll comprises a wound onto a core film strip.
  • the system comprises two roll holders, which are arranged at a distance from one another within a dispenser housing and are connected to the dispenser housing, as well as two bearing journals, henceforth referred to as journals for short.
  • the pins are preferably elements that can be fastened to the end sections of a core of the film roll and, in the fastened state, comprise a bearing section that protrudes beyond the respective end of the core.
  • the end sections of the core can protrude sufficiently beyond the edge of the coiled film strip so that they can be used as bearing journals.
  • the core may be a cylindrical sleeve made of, for example, cardboard. At least a portion of each of the spigots projects axially beyond the adjacent edge of the foil strip wound on the core sleeve when the spigots are located at the ends of the sleeve.
  • Each roll holder comprises a bearing body with a recess, an open insertion area for inserting a pin or a portion of this pin at the top and a bearing area for supporting and at the bottom includes rotatable bearings of the pin.
  • the recess is delimited by an inner edge of the bearing body.
  • the storage area is essentially defined by the lowest level of the inner edge.
  • a section of this inner edge is designed as an insertion ramp with a gradient in the direction of the storage area.
  • the recess includes a bulge laterally adjacent to the bearing area. This serves as a catching space into which the pin can dip when removing a film section from the film roll.
  • the bulge and at least part of the storage area are covered at the top by a portion of the inner rim. This section of the inner edge is a stop or a retaining element, which prevents the pins from jumping out of the storage area in the direction of the insertion area when a film section is pulled off the film roll.
  • each bearing body has a catching ramp with a slope adjacent to the insertion ramp. Together with the insertion ramp, a lowest level or the storage area for the respective pin and thus also the rest position of the film roll to be stored is defined.
  • the gradient of the insertion ramp and the gradient of the capture ramp can be constant or locally different.
  • the inner edge of the recess can be concavely curved in sections or continuously in the insertion ramp, in the storage area and in the catching ramp. This makes it easier for the pegs to roll on the inner edge and reduces frictional forces between the peg and the bearing body when foil sections are pulled off.
  • the pull-out force exerted tangentially on the roll of film causes a torque which causes the roll of film to roll.
  • the pins supported by the bearing bodies roll on the lower inner edge section of the respective recess from the bearing area at least partially in the direction of the catching space.
  • the stop or retaining element limits the freedom of movement of the pins upwards, ie against the direction of gravity. Even if a comparatively light roll of film should be lifted by a sufficiently large tensile force when pulling out a film section, this reliably ensures that the pins through the Retaining elements are retained in the area of the catch area including the storage area.
  • the slope of the inner edge of the catch ramp causes the film roll to be lifted slightly when a section of film is pulled off, thereby exerting a compressive force on the bearing body of the dispenser housing.
  • the inner edge is preferably continuously curved in a concave manner in the area of the catch space. When a section of film is pulled off, this causes the respective pin to roll along this contour and be held securely in the catching space.
  • the rotatable mounting of film rolls in a dispenser housing presupposes that the arrangement and the dimensions of the roll holders, in particular the recesses in the bearing bodies and those of the pins, are matched to one another.
  • Pins are therefore preferably not an integral part of core sleeves, but rather separate adapter elements that can be connected to one or more different core sleeves. They include a connecting section, which can be connected to this core sleeve in a force-fitting and/or form-fitting manner, for example by being inserted into the open end of a core sleeve, and a bearing section which protrudes axially on the core sleeve in the connected state.
  • the core sleeves of film rolls protrude axially beyond the wound film strip, for example approximately 5 mm on each side of the film strip.
  • the length of a core sleeve can, for example, be approximately the same as the width of the foil strip.
  • spigots can be attached to the ends of the respective core sleeve during production of the film rolls or at a later point in time.
  • they can be sold separately as accessories or together with foil rolls or foil dispensers.
  • such film rolls can be supplemented with differently designed pins and thereby adapted to differently designed roll holders arranged in these dispenser housings.
  • Connecting portions of spigots can be used with one or more different types of film rolls.
  • different pins with correspondingly adapted dimensions in the area of the connecting section can be used.
  • such pins are formed in one piece.
  • pegs in the connecting section can include, for example, elements that can be expanded or exchangeable adapter rings with different outside diameters, which enable adaptation to core sleeves with different inside diameters.
  • the bearing sections of pins can also be designed to rotatably mount a film roll in dispenser housings with different roll holders.
  • the spigots may comprise bearing portions having a plurality of areas, each of which areas is suitable for rotatably supporting the roll of film in a dispenser housing having a particular type of roll holder.
  • the outer diameter can be different in each of the areas of a bearing section of the pin.
  • the roll holders comprise bearing bodies in the form of rigid plates, such as stainless steel plates, having a portion disposed vertically or orthogonally to a bottom of the dispenser housing.
  • Such plates preferably have a material thickness in the range from about 1 mm to about 4 mm and can be produced inexpensively and with the required precision, for example by punching and/or laser cutting.
  • the foot area of such plates is preferably bent over in an L-shape.
  • Such plates can be easily and precisely connected to the bottom of the housing, particularly in dispenser housings made of steel, for example by screwing, riveting or welding.
  • Each of the plates has a recess which is open towards the upper end face and is delimited by an inner edge of the plate.
  • the area of the bearing section of a pin protruding from the film roll can be inserted from above into this recess.
  • the recess has a clear width that is greater than the outside diameter of the area of the pin to be accommodated. Therefore, the pin can be moved down along the recess into the storage area and into the catching space.
  • the inner edge of the recess is preferably concavely curved from the insertion ramp over the storage area to the catch ramp.
  • the bearing plates or, in general, the roller holders can comprise more than one such recess. This enables the secured rotatable storage of more than one roll of film in a common dispenser housing.
  • the outside diameter of the pins is smaller than in the area of the connecting section, at least in that part of the bearing section that is guided and displaceable in the recess of the bearing body.
  • the dimensions of the bearing body and the recess on this bearing body can therefore be comparatively small.
  • the space required for the rotatable storage of foil rolls with such journals is significantly smaller than in the case of foil rolls in which protruding sections of the core sleeve are used as bearing journals.
  • Corresponding dispenser housings can be constructed in a comparatively compact manner.
  • FIG 1 shows a cross section of a known film dispenser, which comprises a dispenser housing 1 with two axially spaced roll holders, the roll holders each comprising a bearing body 3 with recesses 5 in which two film rolls 7 are rotatably mounted parallel to one another.
  • the dispenser housing 1 includes a hinged cover 9, which can be opened to insert or remove rolls 7 of film.
  • the dispenser housing 1 comprises a removal opening 11 for each of the foil rolls 7 , which are arranged opposite the pivot axis 9a of the hinged lid 9 .
  • the recesses 5 or the delimiting legs of the plate-shaped bearing body 3 are essentially U-shaped.
  • the adjacent legs of the bearing body 3 are inclined backwards with respect to the vertical direction, and the base of the recess 5 comprises two substantially straight sections arranged in a V-shape.
  • Both film rolls 7 comprise a core sleeve 13 which protrudes axially on both sides beyond the film strip wound thereon. These axially projecting areas of the core sleeves 13 are rotatably mounted in the recesses 5 of the bearing body 3 .
  • FIG 2 shows a perspective view of an open dispenser housing 1 with roll holders designed according to the invention.
  • the front face is not shown for a better view of the dispenser housing 1 .
  • the roll holders are arranged axially spaced apart from one another in the longitudinal direction of the dispenser housing 1 near the two end faces of the dispenser housing 1 .
  • They include bearing bodies 3 in the form of L-shaped curved plates, the shanks of which face each other and are connected to the bottom of the housing.
  • the shanks could also be attached to the bottom of the housing with the opposite orientation.
  • bearing bodies 3 could be connected, for example, to the rear wall of the dispenser housing (not shown).
  • the bearing bodies 3 each comprise a recess 5 with an insertion area 15 which is open towards the upper end face and one on the deepest Storage area 17 arranged at the level of recess 5 and a lateral bulge 19 adjoining it.
  • figure 3 shows the arrangement figure 2 with a film roll 7 mounted in the dispenser housing 1.
  • a pin 2 is arranged at each of the two ends of the core sleeve 13 and is connected to this core sleeve 13 in a rotationally fixed manner.
  • the pin 2 comprises an axially protruding cylindrical section whose outside diameter D1 ( 4 ) is smaller than the clear dimension of the recess 5.
  • the outer diameter D1 can be, for example, of the order of about 10mm to about 25mm and can be, for example, about 20mm, and the length of the axially protruding section is preferably of the order of about 5mm to about 12mm and can be about 9mm, for example.
  • the pin 2 is deflected towards the bearing area 17 by an insertion ramp 21 and then rests as in FIG figure 3 shown at the lowest level of the recess 5.
  • the insertion ramp 21 is an inner edge section of the recess 5 which is arranged between the insertion area 15 and the storage area 17 and which has a gradient or an incline towards the storage area 17.
  • figure 4 shows an end view of the arrangement figure 3 ,
  • a deducted from the film roll 7 end portion of the film strip 7a is shown on a support rod 23 and on the Guide rail 25 of a cutting device on the front upper edge of the dispenser housing 1 rests.
  • the angle of inclination ⁇ of the insertion ramp 21 relative to the horizontal direction is preferably in the range from about 5° to about 45°. Even if the film dispenser rests on a work surface that is not exactly horizontal, this ensures that a film roll 7 assumes a rest position in which each pin 2 is arranged in the bearing area 17 of the respective bearing body 3 .
  • the section of the inner edge of the recess 5 adjoining the bearing area 17 at the bulge 19 can be designed analogously to the insertion ramp 21 as a catch ramp and have an angle of inclination ⁇ relative to the horizontal direction, which is between 0° and about 45°, for example.
  • the sections of the inner edge in the insertion area 15 are preferably inclined by an angle ⁇ relative to the vertical direction, which can be, for example, on the order of magnitude of 0° to about 30°.
  • Bearing bodies 3 with such inclined insertion areas 15 can be manufactured with comparatively small widths L1.
  • the insertion areas 15, which are open at the top are more accessible when the hinged cover 9 is open, which makes it easier to insert and remove film rolls 7. Nevertheless, it is ensured that an upper section of the inner edge in the area of the bulge 19 lies in the bearing area 17 Pin section sufficiently covered, so that this inner edge portion can be used as a retaining element or stop for the pin 2.
  • this stop projects beyond at least half of a pin section mounted in the bearing area 17 .
  • He can as in figure 4 shown include a slightly downward curved nose 27 in the end. If the pin 2 is unrolled along the entire inner edge at the bulge 19 as a result of very large pull-out forces at the end section of the film strip 7a, the film roll 7 finally receives an impulse downwards. This makes it even more difficult for the pins 2 to unintentionally jump out of the recesses 5 of the bearing body 3 .
  • FIG 5 shows an axial end of a film roll 7 and another pin 2 as an exploded view.
  • pin 2 includes the pin 2 in figure 5 axially adjacent to the area with the small outside diameter D1 another cylindrical area with a larger outside diameter D2. These two areas together form a bearing portion of the spigot 2 which protrudes from the film roll 7 when the spigot 2 is attached to the core sleeve 13 thereof.
  • the pin 2 comprises a connecting section which can be inserted into the open end area of the core sleeve 13 and whose outer diameter approximately corresponds to the inner diameter of the core sleeve 13 corresponds.
  • the connecting section can include structures such as protruding ribs 29 for force-fitting connection with the core sleeve 13 .
  • the ribs 29 can be arranged axially and/or radially, as a result of which particularly non-rotatable and/or pull-out-proof connections can be achieved.
  • the connecting section can optionally be slightly conical. This facilitates the insertion and pressing into the respective core sleeve 13 .
  • the length of the connecting section in the axial direction can be, for example, in the range from about 12 mm to about 20 mm, preferably between 14 mm and 15 mm. In further embodiments, the connecting sections can also be longer.
  • the spigot 2 preferably comprises a stop flange 31, the outside diameter of which is larger than the inside diameter of the core sleeve 13 and preferably smaller than the outside diameter D3 of the core sleeve 13.
  • the thickness of the stop flange 31 can range, for example, from about 1 mm to about 3mm lie.
  • the larger outer diameter D2 corresponds to Storage section the outer diameter D3 of the core sleeve 13.
  • This also enables the rotatable storage of a roll of film 7 equipped with such pins 2 in dispenser housings 1, which are designed with conventional roll holders for rotatably storing axially protruding sections of the core sleeve 13.
