Definitions

  • the invention relates to an improved dispenser for strip-shaped roll towels, in particular electronic control, having improved hygiene characteristics and a simplified structure compared to conventional dispensers.
  • the structure of the dispenser may be such that it provides mechanical drive members and any electronic control components, housed in an independent compartment that can be separated from the envelope of the dispenser itself. , further mounted so that they can be disassembled and replaced easily in the event of damage, without having to intervene inside the device.
  • the dispenser according to the present invention is essentially characterized in that it comprises, inside a casing constituted by a rear support bottom, capable of being fixed to a wall, integral with an element of central separation capable of defining, with two upper and lower cover elements, articulated respectively on said bottom, two compartments superimposed and separated from each other, capable of containing, the upper, a roll of clean supply fabric, freely arranged in the horizontal direction, and the lower one, a roll of fabric rewound around a motorized shaft, rotatably mounted at the ends in two flanges of the casing, the path of the fabric from said first roller to said second roller passing around a roller with a rough surface, motorized on the same side as said shaft, disposed in the upper compartment and rotatably mounted at its ends in the two flanges, a second roller mounted on said upper cover element being pr elastically tested against the fabric in the contact area between the rough surface roller and the fabric, the latter then passing around a part of said separating element protruding outward from the front to
  • the operating cycle of the dispenser is electronically controlled by a logic unit capable of driving said motor in one direction or the other, as a function of the setpoint data for the length of the fabric to be dispensed, under form of a number of revolutions made by the motor, adjustable time delay between said distribution and recovery of the fabric, taking into account the different validation elements determined by the closing of the cover elements, by the continuous detection of the presence of the fabric for the interruption when exhausted, as well as protection circuits to suspend the cycle in the event of an obstacle to its correct progress, with the corresponding memorization for the restoration of the fabric cycle at the end of the fault.
  • said motor and the corresponding gears, the electronic components constituting said logic unit which can all be grouped on a card and the possible supply batteries or the transformer-converter in the event of mains supply, are all housed in a closed box, fixed on one side of the casing and, in particular on the flange from which the socket shafts protrude movement of the upper compartment unwinding roller and the lower compartment rewinding shaft.
  • the mechanical members can thus be repaired or replaced separately since they are removable from motorized shafts and this is also applicable to electronic components by possible replacement of the card after having disconnected it.
  • the casing preferably made of resin to eliminate corrosion, to reduce the masses and to be able to avoid the costs of painting or chemical treatment, may be removable, with right and left flanges with elastic snap mounting.
  • An extremely important aspect of the present invention is due to the fact that said beak-shaped protrusions, on one side and on the other of said separation element around which the loop of fabric is formed, can also be brought together and arranged so to make everything inaccessible from the outside when the device is at rest; the extremely reduced path of the clean tissue, wound around the end of said separating element can therefore no longer be soiled in any way.
  • the dispenser 1 comprises a casing 10 constituted by a rear structure or support base 11, capable of being fixed by known means to a wall, and by a central separation element 14 constituted, by example, but not necessarily, by two opposite curved walls 14a, 14b, the concavity of which is turned up and down respectively.
  • a central separation element 14 constituted, by example, but not necessarily, by two opposite curved walls 14a, 14b, the concavity of which is turned up and down respectively.
  • a curved upper cover element 12 At the upper end of the bottom 11 is articulated, at 12 ′, a curved upper cover element 12, and similarly, at the bottom, is articulated, at 13 ′, a lower cover element 13, capable of joining on the front of the device in the closed position, as will be better explained later.
  • the partition 14 and, more precisely, the element 14a defines an upper compartment 22 upwards, and the element 14b, downwards, a lower compartment 23, completely separated. one of the other.
  • a portion 15 in the form of a console in a plane inclined downwards, opposite which the upper covers 12 and lower 13 both have an element protruding, beak-shaped, respectively 12a and 13a, which extend outward at least as much as said projection 15.
  • a roller 32 for feeding the strip of fabric 2 to be used as a towel Said inert roller rests freely on the bottom of compartment 22, while in compartment 23, a roller 33 of dirty fabric, already used, rewinds around a shaft 35.
  • the shaft 35 is rotatably mounted at its ends in the flanges 16 and 17 of the casing and is connected, on one side (on the side of the flange 16 in the figures), to a drive mechanism driven by a motor M.
  • the shaft 35 On the other side, where it is mounted in the flange 17 , the shaft 35 is housed so that it can be extracted from its support, for example on the bottom of a groove 37 formed on said flange 17 of the device where elastic means 39, such as a helical spring, are provided to keep the shaft 35 constantly under stress towards the mechanical connection at the other end.
  • elastic means 39 such as a helical spring
  • the roller 25 which determines the unwinding of the fabric 2 from the roller 32, is motorized at one end and, in particular, on the same side as that on which the shaft 35 is driven, and is also connected, as explained later, to the unique engine M of the device.
  • rollers in the dispenser or labyrinth passages for the fabric strip 2 which simply slides down and forward along the inclined console 15, up to to reach the outside, between the projecting elements in the shape of a beak 12a, 13a, through the slot 19, and which forms a very narrow or flattened loop, having two parallel sides and very close to each other , until returning to the interior of the device, still through said slot 19, this time under the separating element 15, to finally wind up on the roller 33.
  • the element 15 therefore constitutes an extension towards the outside of the separation between the upper compartment 22 and the lower compartment 23.
  • the slot 19 can thus be straight and also that the outer edge of the separating element 15 can be set back with respect to the two beak-shaped projections 12a, 13a, which makes contact practically impossible. with the part of tissue withdrawn inwards and stretched around said edge of the element 15 when the appliance is not in service, as will be better explained later.
  • the apparatus described according to the present invention is characterized by the original path of the fabric strip and by the fact that the clean feed roller is disposed above the rewinding roller of the fabric used.
  • This dispensing device is also particularly suitable for being controlled electronically and therefore has additional advantages which have already been partially stressed before.
  • the support separating element 15 may have in its central part a zone sensitive to contact, for example, with a movable key 41, connected in any known manner to a microswitch 43. Opposite of said zone 41, the projecting part 12a of the upper cover has a notch 45 in its outer edge, so that the key 41 is accessible and can be operated with a finger.
  • the control push button located below.
  • the microswitch controls the starting of the motor M in the direction corresponding to the drive of the unwinding roller 25, which makes it possible to unwind a predetermined length of fabric 2 which is placed outside, as shown in FIG. 2, d 'a particularly pleasant way to be used as a double hand towel, since the user can have both front and rear panels, perfectly clean.
  • the motor After a predetermined time, fixed by an adjustable timer T, the motor will be actuated in the opposite direction to the previous one, to drive in motion the shaft 35 until all of the fabric 2 present on the outside has been returned, by exerting a certain tension around the element 15, so that it remains accessible from the outside only the small area located above the area 41 and left uncovered by the notch 45, and that the this will allow you to start a new dispenser operating cycle.
  • the slot 19 will preferably be of a width such that it will allow the two sides of the fabric 2 to pass, while preventing however that one can introduce a hand or a single finger to come into contact with the stretched fabric. on the outer edge of the element 15, as indicated above.
  • Said fabric tension upon completion of the rewinding, can be used to improve the reliability of the cycle by introducing this data as protection against possible false operations, in the form of an additional validation in the electronic circuit, at the input of a logic control unit L, as will be better described later by referring Reference to FIG. 5. It can be said for the moment that when entering the device, the fabric 2 is forced to follow an S-shaped path between two parallel ribs, 48, 48a of the part 13a and an intermediate element tilting 47, parallel to said ribs and articulated by means of arms 49 on a small shaft 51 rotatably mounted at the ends, in the flanges of the device.
  • Another important object of the device sensitive to the tension of the fabric 2 is the detection of the exhaustion of the roller and therefore the end of cycle control and the extinction of the device.
  • the microswitch 43 may be made for the microswitch 43 to control the actuation of the motor M to drive the roller 25 and unwind a predetermined length of fabric, only if the element 47 "detects" the tension determined by rewinding following the previous cycle. This means that it will not be possible to call up a next length of fabric 2 until that which has already been taken out has not been completely taken in.
  • the housing 20 contains the electronic card L which produces the logic control unit, a power supply A consisting of a series of batteries or by a transformer-converter in the event of power supply, a reversible DC motor and the movement transmission mechanisms corresponding to shafts 25 and 35, not shown in FIG. 1 in order to be better illustrated separately in FIG. 4.
  • a power supply A consisting of a series of batteries or by a transformer-converter in the event of power supply
  • a reversible DC motor and the movement transmission mechanisms corresponding to shafts 25 and 35, not shown in FIG. 1 in order to be better illustrated separately in FIG. 4.
  • the various connections between the power supply A, the motor M and the electronic card L as shown schematically in Figure 5, as well as the indicator lights R and V.
  • the shaft 61 at the output of the motor M, is connected by a unidirectional coupler 62 of known type to a shaft 63 on which is fixed an endless screw 64 meshing with a pinion 65, coaxial with the roller 25.
  • a pinion 71 On said drive shaft 61 is wedged a pinion 71 which, by means of a pair of additional gears 71a, 71b, is connected by means of a second unidirectional coupler 72, to a shaft 73 on which is fixed an endless screw 74 coming to mesh with a pinion 75 coaxial with the rewinding shaft 35.
  • the unidirectional couplers 62, 72 are capable of rotating their driven parts, this is ie, respectively, the shaft 63 or 73, only in a specific direction of rotation of the motor shaft 61, so that if the latter rotates, for example, clockwise, the movement is transmitted only to the tree 63 (or 73) and, by the latter to the tree 25 (or 35), while the other remains stationary, and rec iproquently for a rotation anticlockwise.
  • A1 supplies power, via a pilot circuit P controlled by the output of the logic unit L , the motor M, as well as the logic unit in question and a circuit of the protections and the corresponding CPM memories.
  • the logic unit L produced in the form of a simple card as indicated above, receives as input, in addition to the supply current of A1, the signals of the CPM circuit, the signals for enabling the cycle start microswitch.
  • the logic unit L gives, at the output, the appropriate control signal so that the pilot circuit P supplies, with the required polarity (depending on whether it is necessary to rotate in one direction or in the other to control the unwinding or rewinding of the fabric) and for the necessary time the motor M.
  • Adequate light signals by means of light-emitting diodes, red R and green V, indicate the operating state of the device in a known manner, for example the exhaustion of the fabric or, when the closing contact of the cover C is opened, the state of control of the batteries, as indicated in CB.
  • the device Given the high sanitary characteristics of the device according to the invention, it is possible to use for feeding a closed refill which contains a sterilized roller and from which by a slit which is loosened at the time of loading, the tissue can be taken out for start of the cycle while maintaining, during use, the desired sterility characteristics.
