摘要:
Apparatus for dispensing paper from rolls which feeds continuously, roll to roll, and does not require extra procedure to bring stub roll into position. The apparatus has means for holding and positioning at least first and second rolls of paper with respect to each other; means for dispensing paper from the first roll; means for dispensing paper from the first and second rolls simultaneously whent he first roll reduces to a predetermined diameter of paper, means for positioning the depleted first roll for replacement without the necessity of removing the second roll; and, means for dispensing from the second and replacement rolls simultaneously when the second roll reduces to a predetermined diameter of paper. The apparatus also has a capacity-change-based proximity sensor comprising a circuit according to a balanced bridge principle where detection is based on detecting a phase difference, which depends upon the amount of detected capacitance difference or change. The proximity detector senses when a hand is placed near the dispenser, and thereupon dispenses a set amount of towel. It does not keep dispensing the towel. The hand must be withdrawn and placed in proximity to the sensor again. The proximity sensor incorporates "static" and noise-immunity circuitry. The dispenser incorporates means for dissipating static charges to a local ground.

The device for distributing wiping material comprises a casing (1), a hood (2), a drum (3), a cutting blade (4a) which is integrated into the drum, means for launching and recalling said drum including an eccentric (6) and a launching and recall spring (6a) disposed on a side part of the drum, lateral flanges (1b) of the casing which are specially designed to support a reel (B) of material, a pressing roller (8) providing pressure with respect to said strip of material at a given point, in addition to a second pressure area defined in the cutting area of the strip of material at the level of the drum. The inventive device is characterized in that the pressing roller (8) is hingedly mounted and able to pivot by means of two swing levers (9-10) so that it can come into permanent contact with the reel of material (B) in a state of pressure, defining a distance between the areas of tension defined by the reel contact/ pressing roller and the drum/egress of the cutting blade, corresponding to 25-50 cm.

Appareil distributeur de matériau d'essuyage du type comprenant un carter de fixation murale (1) et un capot (2). Des flasques latéraux reçoivent à rotation libre les axes (3a) d'un tambour (3) incluant une lame de coupe (4a). Un mécanisme de chargement inclut une molette (20) de chargement montée sur un axe (21) solidaire du flasque de l'appareil. Cette molette présente une première couronne (20a) susceptible de déborder sensiblement hors de l'appareil pour permettre sa manipulation par l'opérateur. Cette molette comprend axialement une deuxième couronne (20b) de diamètre plus réduit qui coopère avec un pignon (22) intermédiaire monté sur un axe (23) tournant sur le flasque (1b), ledit pignon intermédiaire (23) coopérant avec une couronne (24) dentée montée en bout de l'axe (3a) du tambour (3). Selon l'invention, la molette de chargement est agencée avec un dispositif anti-retour (DA) aménagé avec et dans les couronnes (20a) et (20b) du type à roue libre.
摘要:
Mechanism for cutting and distributing portions of sheet, particularly paper towels, comprising at least one cylinder (9) which can rotate around its axis in a supporting structure (1,2,3) and drag an end portion (8) of at least one sheet, inside said cylinder (9) being arranged one or more movable blades (28) which can protrude outside the cylinder (9) for cutting said end portion (8) of the sheet and are fixed to a shaft (26) suitable for rotating around an axis parallel to the longitudinal axis of the cylinder (9), wherein said shaft (26) is provided with at least a first member (30) which protrudes from one side of the cylinder (9) and can be rotated for an arc of a circumference by at least a second member (25) which shifts in a direction parallel to the longitudinal axis of the shaft (26) of the movable blades (28) and rotates around the axis, the rotational-translational motion of this second member (25) being synchronized with the rotatory motion of the cylinder (9). Towel dispencer comprising said mechanism.
摘要:
The invention concerns a dispenser comprising a device for lock-stopping the drum (6) arranged in the form of a shaped hook (18) mounted in free articulation on the pressing roll (11) shaft, said hook (18) being provided with a lower portion forming an arm (18b) capable of being arranged opposite and resting on the belt (16) in the shaped groove (6g), said arm (18b) end having a projecting form designed to be in contact with the belt (16) and prevent the drum (6) from rotating backwards after the material strip has been cut.
摘要:
Ein Zeitschalter weist ein rückstellendes, bewegliches Schaltglied (5) auf, an dem ein gegen einen Gegenkörper (11) preßbarer Saugnapf (3) vorgesehen ist. Der Querschnitt einer Lufteinlaßöffnung (9) in den Unterdruckraum (10) zwischen dem Gegenkörper (11) und dem angepreßten Saugnapf (3) bestimmt die Schaltzeit und ist vorzugsweise einstellbar. In den Unterdruckraum (10) mündet zusätzlich eine Belüftungsöffnung (12), der ein abnehmbares Verschlußelement (13) zugeordnet ist.
摘要:
The invention relates to a towel dispenser (10) such as a paper towel dispenser comprising a housing (12) in which a paper roll and an issuing device (50) are arranged. Said issuing device can be controlled by a sensor (38). In order to simplify the operation and to increase the reliability of the towel dispenser, the invention provides that the sensor (38) is configured as a capacitive sensor.
