Definitions

  • This invention concerns an automatic dispenser for paper towels which are severable from a continuous roll in the shape of predetermined length strips made available on the outside of the dispensing apparatus so that they can be subsequently torn off manually against a stationary blade in a relatively hidden position within the device according to the preamble of claim 1.
  • a number of types of paper towel dispensers are already known, adapted in particular to enable a manual pulling of the free flap which has remained accessible after a previous usage, and the "ripping" thereof against a stationary blade.
  • a brake device is sometimes provided which is adapted to block the unwinding of the strip from the feed roll, after a certain length, thereby making it easier to tear off the paper to be used, whereafter a further clean flap of material may be allowed to project outside to be manually grabbed for a subsequent usage cycle.
  • a side crank or handle is provided for rotating the feed roll in the unwinding direction, in order to have available on the outside a paper strip of a desired length.
  • the inventive device includes a housing thereof comprising a wall mounted support portion 1 having a back portion 31 adapted to be fastened to a wall, two side walls 41a and 41b and a paper feed roll support comprising a pair of bracket or cantilever members, 43a, 43b, having a substantially semi-circular recess 45a, 45b adapted to provide a rolling engagement seat for the ends of a tubular member 25 used as a core for roll 10.
  • Cover 2 has a downwards facing paper dispensing port 2a, directed in such a way as to provide a guiding action for paper 10a towards the outside, after the paper has passed in front of a cutting blade 3 mounted on cover 2 in a position set back within the recess defined by port 2a, in order to be scarcely accessible from outside.
  • said recess is protected also on the sides, at both ends of dispensing port 2a, by a pair of walls 2b integral with cover 2 as well.
  • Paper dispensing is performed by dragging the paper by means of a pulling roller 12 actuated by a small motor 8 fastened to support portion 1, in particular on an internal side shoulder 7 thereof.
  • pinion 8 on the motor output shaft meshes with a first gear 9 of a reduction gar whose second gear 9a meshes in turn with a further motion transmitting gear 11 mounted on roller 12 shaft.
  • roller 12 Paper 10a coming from roll 10 is led between the surface of roller 12 and a confronting roller 13 rotatingly mounted for instance on a pair of journals fastened to the ends thereof, each of them being rotatable within a small support plate 14 provided with biasing springs 15 adapted to press the opposing roller 13 against dragging roller 12.
  • roller 12 will be made of a certain number of cylindrical rubber lined members integrally provided on a shaft rotatably mounted, at the ends thereof, on structural parts of support 1, like for instance shoulder 7 mentioned above and a rib 7a on the opposite side, which supports as well the corresponding end of opposing roller 13 as it is best shown in Figure 4.
  • stationary tongue shaped members, or the like may be provided in order to prevent the paper from winding back around roller 12 and to induce the paper along its regular path.
  • the dispensing control is performed by means of a switch 17 actuated through a pushbutton 6, comprising for instance a flexible blade having one end fastened to cover 2, and bearing on the switch 17 in order to supply power to motor 8 through a timer 18, the power supply being made available as a rectified 12V DC current from a transformer 23 connected to the grid.
  • a printed control circuit 16 connects switch 17 to timer 18 as well as to a LED 19 for displaying the apparatus operating condition, the assembly being mechanically supported by said shoulder 7 integral with support 1, while cover 2 carries, besides pushbutton 6, also a clear inspection hole 20 to display the LED light.
  • transformer 23, together with program printed circuit 22, is mounted within a support or fastening box 21 on the bottom of back panel 31, in order to be accessible only upon having withdrawn fastening screws 26 and after having necessarily taken the device off the supporting wall. The same holds true to gain access to the location of electrical connections 27, which is protected from the outside by means of a cover 24, still on the back side of the device.
  • roller 13 will preferably be rendered rough, by any known method, according to the material thereof (wood, plastics, and so on), in particular in the central area of said roller 13, having preferably a larger diameter.
  • the paper dragging action will be more effective in the roller central area, and in particular dragging roller 12 will comprise a number of rubber lined cylindrical areas, separate from each other, whose size is increasing towards the center, in order to prevent the paper from contacting the rollers along the whole width thereof, which might cause the paper to curl if the paper were irregularly engaged within the roller nip.
  • friction is concentrated in a single central area corresponding to the enlarged and knurled portion of roller 13 and to the central rubber lined cylinder of roller 12, while the other cylindrical portions thereof provide more of a guiding than of a dragging action.
  • Actuation is performed by enabling, by means of switch 17 controlled through pushbutton 6, a potentiometer or timer 18 which, as it is more clearly shown in the block diagram of Figure 5, makes it possible to supply motor 8 for a predetermined time, with DC electrical power coming from the rectified output of transformer 23.
  • a photoelectric cell or proximity switch control might be provided in a completely similar arrangement.
  • LED 19 may be the normally lit type, being turned off while the device is operating, i.e.
  • motor 8 is actuated, or vice-versa it might be normally off, with a red light being turned on during operation to warn the user that a further actuation of pushbutton 6 or photoelectric cell will have no result.
  • the printed circuit 16 connections will be such as to prevent any further operating cycle until switch 17 is in any way actuated, in order to prevent the paper from unrolling continuously for instance in case a match or similar sharp member is inserted to keep pushbutton 6 in a depressed position, or else if the photoelectric cell is kept persistently blinded.
  • the actuation time may be set on timer 18 by the service personnel only, and only after the cover has been opened to gain access to shoulder 7 carrying said control members, as well as for possible maintenance of the mechanical parts.
  • the overall actuation time will depend upon the unrolling speed, therefore on roller 12 peripheral speed, but in any case it will be long enough to let out a paper flap 10a of a sufficient length for various uses.
  • a "pause" period will further be provided, during which any actuation will have no result. This will be provided for instance by arranging that timer 18 may inhibit, for a predetermined time period a new actuation of motor 8, starting from the end of an operation thereof.
  • transformer 23 is shown therein as being supplied with power from the grid through a fuse 23a, whose secondary side supplies separately the reduced voltage driving motor 8 and an enable circuit for actuating said motor.
  • the pair of DC supply circuits are shown at 22, which is the same reference number used for the program printed circuit of Figure 4.
  • the enable circuit which may comprise the printed control circuit 16 of Figure 2, includes an ON-OFF circuit 34, in series to switch 17, which is possibly actuated not through a push-button but by means of an electronic or photoelectric cell control, or proximity detector.
  • an operating distance control 34a may be provided, said enable circuit including as well timer 18 with an associated control 18a of the operating time, therefore of the amount of paper dispensed, as well as a pause circuit 32 and relevant controls 32a.
  • the pause circuit prevents timer 18 from enabling a subsequent operation, for a predetermied time period after motor 8 has stopped its operating cycle, as controlled by said timer. Therefore, after a cycle has been started, the whole time period set in the timer 18 will have to elapse (during which motor 8 is in operation and rotates dragging roller 12 which dispenses the paper) as well as the whole time period set in pause circuit 32, possibly adjustable in 32a, before next cycle can be started.
  • Indicator light 19 of the dispenser operating condition might indicate as well if the motor is operating or not, and possibly also the pause period, as mentioned above, thereby indicating if the dispenser can be actuated or not.
