Definitions

  • the subject matter of the invention is a pin for the rotatable mounting of a film roll or a flat structure wound onto a core sleeve 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 disposable containers that are disposed of as soon as the film supply has been completely used up.
  • Foil rolls for commercial purposes are comparatively large. They comprise foil strips wound onto a core sleeve, the length of which can be, for example, of the order of around 100 m to around 600 m, and the width of which is typically in the range of around 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 metal housing and is designed to accommodate two different foil rolls in a space-saving manner.
  • the foil rolls each comprise a core sleeve with different diameters 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.
  • foil rolls With such foil dispensers, only foil rolls can be rotatably mounted in the roll holders, the dimensions of which, in particular the lengths, outer diameter and inner diameter of the core sleeves, are exactly on the respective Role holders are matched.
  • the possible uses of film rolls are also limited. They can only be used in film dispensers whose roll holders are designed and arranged in such a way that such film rolls can be rotatably mounted therein.
  • the pin is an adapter that, as a link, enables a film roll to be rotatably mounted in dispenser housings with different roll holders.
  • a pin is attached to each end of the core sleeve of this film roll.
  • journals are also referred to as bearing journals or adapter journals.
  • Each pin preferably comprises a wall which radially delimits an internal cavity. Such pins can be made with comparatively little material and are correspondingly light.
  • the spigot comprises a connecting section which can be connected to a film roll, for example by being pressed into one of the open end sections of the core sleeve of a film roll.
  • the spigot comprises a bearing section with at least two cylindrical areas that have a different outside diameter.
  • the outer diameter of the axially inner cylindrical section or closer to the connection area can, for example, be smaller than that of the axially outer cylindrical section.
  • the larger outside diameter can in particular correspond to the outside diameter of the core sleeve onto which the film strip is wound.
  • Foil rolls in which such spigots are attached to the ends of the core tube can be used, for example, in foil dispensers whose roll holders are designed for directly supporting protruding end portions of the core tube.
  • the cylindrical area with the smaller outside diameter that is closer to the connecting section can be used for rotatably mounting the film roll on bearing bodies that comprise comparatively narrow recesses for receiving bearing elements that protrude axially on the film roll.
  • the core sleeves of film rolls protrude axially beyond the coiled film strip, for example about 5mm on each side of the film strip.
  • the length of a core sleeve can, for example, be approximately the same size 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.
  • Connecting portions of spigots may be designed for use 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 preferably designed in one piece, so that they can be produced inexpensively in large numbers.
  • pegs in the connecting section can include, for example, expandable elements or interchangeable adapter rings with different outside diameters, which enable adaptation to core sleeves with different inside diameters.
  • 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 adjoining legs of the bearing body 3 are inclined backwards with respect to the vertical direction, and the base of the recess 5 comprises two essentially 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 outstanding 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 other roll holders on which a roll of film is mounted by means of bearing pins.
  • 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. In alternative embodiments, 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 open towards the upper end face, a bearing area 17 arranged at the lowest level of the recess 5 and a lateral bulge 19 adjoining it.
  • 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 includes an axially outstanding cylindrical section whose outer diameter D1 is smaller than the clear dimension of the recess 5.
  • the outer diameter D1 can be, for example, in 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 in the order of about 5mm to about 12mm and can be about 9mm, for example.
  • FIG 3 shows an axial end portion of a film roll 7 and a pin 2 according to the present invention as an exploded view.
  • pin 2 includes the pin 2 in figure 3 coaxially adjacent to the area with the small outer diameter D1 another cylindrical area with a larger outer diameter D2.
  • the spigot 2 comprises an open end portion the connecting section which can be inserted into the core sleeve 13 and whose outer diameter corresponds approximately to the inner diameter of the core sleeve 13 .
  • the connecting section can include structures such as protruding ribs 29 for force-fitting connection to 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 L1 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. This is sufficient for a secure connection of the spigot 2 to the core sleeve 13, the total length L of the spigot 2 and its weight or the amount of material required to produce the spigot being comparatively small.
  • the connecting sections can also be longer.
  • the pin 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 Stop flange 31 protrudes radially beyond the connecting flange.
  • the thickness L4 of the stop flange 31 may range from about 1mm to about 3mm.
  • the stop flange 31 defines the end position of the pin 2 when it hits the core sleeve 13.
  • the length L2 of the cylindrical section with the smaller outer diameter D1 is preferably in the order of about 5 mm to about 12 mm and can be about 9 mm, for example.
  • the length L3 of the cylindrical section with the larger outside diameter D2 is preferably on the order of about 8 mm to about 18 mm and can be about 13 mm, for example.
  • the larger outer diameter D2 is preferably in the range from approximately 30 mm to approximately 60 mm and can in particular be 48 mm. This is a common value for the outside diameter of core sleeves.
  • figure 4 shows a longitudinal section of the film roll 7 from figure 3 in the end region of the core sleeve 13, the spigot 2 being connected to this core sleeve 13 by pressing the connecting section into the open end of the core sleeve 13.
  • figure 5 shows an enlarged longitudinal section of the Figures 3 and 4 shown pin 2.
  • the axially outer cylindrical portion with the larger outer diameter D2 includes a continuous bottom 4, the coaxial adjacent cylindrical area with the smaller outer diameter D1 partially or completely covered. This improves the stability of the pin 2.
  • the pin 2 can include inwardly protruding ribs 33 to improve stability ( Figure 5a ).
  • the base 4 can include one or more bores or openings 35 in the central area, so that the spigot 2 or its wall delimits an axially continuous interior space, which can in particular be tubular. This has the advantage that when the pins 2 are pressed into the core sleeve 13, no excess pressure can arise that would cause a counteracting force to the pressing-in force.
  • Figure 5a shows an embodiment of the pin 2 with a continuous central opening 35 and with radially inwardly protruding ribs 33 to increase the stability of the pin 2.
  • Such ribs 33 preferably extend as in FIG Figure 5a shown axially over the entire length of the spigot 2.
  • Spigot 2 without a continuous central opening 35 can also comprise such reinforcing ribs.
  • the larger outside diameter D2 of the bearing section corresponds to the outside diameter D3 of the core sleeve 13.
  • figure 6 shows analogous to figure 2 an arrangement with a roll of film 7 mounted in the dispenser housing 1.
  • the pins 2 correspond to the embodiment according to FIG figure 3 .
  • the area of the journal 2 with the larger outer diameter D2 is arranged axially on the outside of the bearing body 3.
  • the film roll 7 is additionally secured against axial displacement.
  • the axially outer areas of the pins 2 with the larger outside diameters D2 are tubular. They can therefore be used as gripping openings for easy insertion and removal of film rolls 7 in the dispenser housing 1 .
  • FIG figure 7 shows a longitudinal section of a foil dispenser in the area of one of the bearing bodies 3, with a foil roll 7 having a pin 2 according to FIG figure 4 is rotatably mounted on this bearing body 3.
  • the outer cylindrical section of the pin 2 with the larger outside diameter D2 lies in a correspondingly large recess 5 of the bearing body 3.
  • figure 8 shows a similar arrangement as figure 7 with the same film roll 7 and the same pin 2.
  • the inner one cylindrical section of the pin 2 with the smaller outer diameter D1 in a narrower recess 5 of the bearing body 3, as is shown in figure 6 is shown.
  • the pin 2 is preferably made of one or more plastic injection molded parts.
  • the connecting section of the pin 2 could also be designed differently.
  • it could be longer and/or in two parts.
  • it could comprise a base for attaching different adapter parts optimized for connection with different core sleeves 13 (not shown).
