Description

DESCRIPTION

Thin paper dispenser

TECHNICAL SECTOR

The present invention relates to a dispenser for thin paper, such as cigarette paper, or other similar materials with a density lower than 18 g / m2.

STATE OF THE ART

Dispensers for napkins, towels and other types of cellulosic sheet material are known. These equipments are used, for example, in public toilets for drying hands.

These dispensers require a certain stiffness of the paper, which is achieved by its density. Therefore, they are not applicable to sheets of cigarette paper or other similar products, where the brittleness and low density (between 10 and 18 g / m2, usually between 12-14 g / m2) of the supplied material impose significant limitations.

The applicant does not know of any device similar to the invention, which can be considered as a solution to the same technical problems.

BRIEF EXPLANATION OF THE INVENTION

The invention consists of a dispenser for thin paper, such as cigarette paper, according to the claims.

Thus, the thin paper dispenser comprises a housing with a slot or hole for dispensing the cut paper, and a knob. The casing contains a thin paper roll, paper drive motor rollers, and cutting equipment. In a novel way, the cutting equipment to ensure that the cut is clean comprises a scissors.

The dispenser can be configured to dispense paper in two or more different lengths, which are preferably configurable.

Other particular embodiments will be discussed later, with the support of the figures.

DESCRIPTION OF THE DRAWINGS

For a better understanding of the invention, the following figures are included.

Figure 1 represents an exploded diagram of a first embodiment.

Figure 2 represents an exploded view of the rollers in the previous embodiment.

Figure 3 represents an exploded view of the cutting means in the embodiment of Figure 1.

MODES OF EMBODIMENT OF THE INVENTION

An embodiment of the invention will be briefly described below, as an illustrative and non-limiting example thereof.

Figure 1 shows an exploded view of a first embodiment of the invention. Part of a protective casing (1), which contains a base for mounting the other components. The casing (1) has a slot (2) for dispensing the paper and a knob (3) for handling it. For example, it can comprise two variants to be supplied according to their length (78 and 108 mm) for a standard width of 44 mm, although the length of the supplied papers can be configurable.

The inside of the casing (1) contains a paper supply spool (4), which should be changed when it runs out. The capacity of the reel (4) is not relevant, but the normal thing is that it has 600 m of paper. The paper passes through at least one pair of drive rollers (5). At least one tractor roller (5) of each pair is motorized. The turning speed of the traction rollers (5) will be slow.

One or more diverter rollers (6) ensure that the paper enters or leaves the tractor rollers (5) with the necessary orientation. These diverter rollers (6) or the pulling rollers (5) can be on rotating or mobile supports (figure 2) against a spring (5 ') to give tension to the paper. The rollers (5,6) will have non-slip finishes, especially those that are mounted on springs (5 '). They will be arranged in a Make sure the smallest radius turn is opposite to the roll (4) turn to correct for any curl in the paper. That is, the path of the paper is defined in such a way that the curve with the smallest radius is opposite to the direction of the coil.

A guide in the slot of two fixed slats ensures that the paper is perfectly fixed and aligned with a cutting equipment (8) made up of scissors to ensure that the paper does not tear. The slats are arranged on both sides of the scissors to avoid unwanted movements. The cutting equipment (8) is actuated by a motor and gear assembly (7) as shown in figure 3.

The entire system is managed by a control unit, a printed plate, which manages the rotation of the traction rollers (5), preferably with stepper motors. It also allows you to offer the different cut lengths of the paper or vary these. The motor of the traction rollers (5) will be of reduced consumption and of very high torque, controlled by means of PWM ( pulse width modulation) or pulse width modulation.

A series of sensors, not shown, check the length of paper served, the position of the scissors ... They can also detect if the paper has run out, has broken or is blocked, for example, observing an excessively high resistance or low to the rotation of the traction rollers (5) or a strange consumption of its motor.

The knob (3) is preferably a touch screen that functions as an interface. In addition to allowing the control unit to be given orders, it can present animations. In the part that remains inside the housing (1) it can have a port, for example a microSD card reader, for updating. It can also be a USB port or similar for a modem that allows its update from a server.

The housing (1) may have an opening sensor, such as a HALL type magnetic sensor, to block any moving part if the housing (1) is open. Especially the cutting equipment (8).
