Description

The present invention relates to a cigarette butt fire extinguishing device that automatically extinguishes a cigarette butt fire.

Passive smoking, in which the smoke of another person's cigarette is inhaled, may harm human health. In recent years, in order to prevent second-hand smoke, smoking booths have been set up in one area of the facility, such as family restaurants and shopping malls, where many people gather, so that they can smoke only in a specific partitioned space. I have something to do. The smoking booth may be equipped with a cigarette butt fire extinguisher that extinguishes and collects cigarettes. As a technique related to such a cigarette butt fire extinguishing device, a cigarette butt is received from an inlet, and a pair of cutting rollers configured so that the peripheral surfaces having a plurality of blades mesh with each other cuts the cigarette butt and fragments. It is known that the fire extinguishing fire is extinguished by extinguishing the fire while generating the fire, and then pressing the debris that has fallen from the cutting roller with a pair of pressing rollers that elastically deform and make surface contact to shut off the fire from the air. (Patent Document 1).

In addition, as a technology related to other cigarette butts fire extinguishing devices, cigarette butts are accepted from the inlet.
A pair of fire extinguishing rollers presses the butts to shut them out of the air to extinguish the fire, and then another pair of fire extinguishing rollers further presses the butts to shut them out of the air to extinguish the fire. , A pair of crushing rollers is used to cut the butts into small pieces (Patent Document 2).

Japanese Patent No. 5475913 Japanese Unexamined Patent Publication No. 8-51970

However, the one described in Patent Document 1 has a large number of parts and a complicated structure, and has a structure in which a pressing roller is arranged under a cutting roller, so that the dimension in the height direction becomes large. Further, the pair of pressing rollers have a structure in which elastically deformed hard rubbers are constantly pressed against each other by a coil spring, and many members are prone to deterioration, which may cause a problem in durability.

The structure described in Patent Document 2 has a large number of parts and a complicated structure, and has a structure in which another pair of fire extinguishing rollers is arranged under a pair of fire extinguishing rollers and a crushing roller is further arranged below. The dimension in the height direction becomes large. Further, since the fire extinguishing roller is formed of a cylindrical metal, the contact area with the passing butts is small, the temperature of the butts is difficult to decrease, and oxygen is difficult to shut off, so that the fire extinguishing efficiency may be low. .. For this reason, it seems that a pair of fire extinguishing rollers is required in two stages in order to extinguish the butts.

The present invention has been made under such circumstances, and an object of the present invention is to provide a cigarette butts fire extinguishing apparatus having a simple structure, a small number of parts, and being compact, yet having excellent durability and fire extinguishing properties. ..

In order to solve the above problems, the butts fire extinguishing device (1) according to the present invention is rotatably supported around the introduction portion (ash tray lid 11d) of the butts and the introduction portion, and is supported on the outer peripheral surface. A first fire extinguishing roller (30, 30A, 30B) provided with a plurality of first ridges (33, 33A, 33B) in the circumferential direction, and below the introduction portion, rotatably supported around the axis and on the outer peripheral surface. A second fire extinguishing roller (40, 40A, 40B) provided with a plurality of second convex stripes (43, 43A, 43B) in the circumferential direction, and the first fire extinguishing roller and the second fire extinguishing roller arranged in parallel are inside each other. A drive mechanism (50) that is rotationally driven in a direction is provided, and the first ridges are arranged so as to enter with a predetermined gap between the second ridges. The butts received from the introduction portion are arranged so as to enter with a predetermined gap between the first protrusions, and the outer peripheral surface of the first fire extinguishing roller and the second fire extinguishing roller It is characterized in that the fire is extinguished by being sandwiched between the outer peripheral surfaces and pressed.

With this configuration, the butts can be extinguished by using two rollers (first fire extinguishing roller and second fire extinguishing roller) arranged in parallel, so that the dimension in the height direction can be reduced.

Further, since the first fire extinguishing roller and the second fire extinguishing roller do not need to be elastically deformed and can be formed of metal, heat absorption and fire extinguishing can be promoted and durability can be improved.

Further, when the butts are extinguished by being sandwiched between the outer peripheral surface of the first fire extinguishing roller and the outer peripheral surface of the second fire extinguishing roller and pressed, the first ridges form a predetermined gap between the second ridges. The second ridges are arranged so as to have a predetermined gap between the first ridges so that the butts can be inserted into the outer peripheral surface of the first fire extinguishing roller. 2 The contact area when pressed against the outer peripheral surface of the fire extinguishing roller can be increased. Therefore, the temperature of the butts can be easily lowered and the supply of oxygen to the butts can be easily cut off, so that the fire extinguishing efficiency can be improved.

Further, by providing a gap between the first convex and the second convex, the pressure is guided to the pressing start point where the pressing is started by being sandwiched between the outer peripheral surface of the first fire extinguishing roller and the outer peripheral surface of the second fire extinguishing roller. Since the cigarette butts are easily sandwiched between the outer peripheral surface of the first fire extinguishing roller and the outer peripheral surface of the second fire extinguishing roller, the fire extinguishing efficiency can be improved.

In this case, it is preferable that lateral grooves (34, 44, 44B) parallel to the axial direction are formed on the outer peripheral surfaces of the first fire extinguishing roller and the second fire extinguishing roller.

With this configuration, the butts on the first fire extinguishing roller or the second fire extinguishing roller are dropped into the lateral groove, and the pressing is started by being sandwiched between the outer peripheral surface of the first fire extinguishing roller and the outer peripheral surface of the second fire extinguishing roller. Since it can be guided to the pressing start point, the time for the butts to stay on the first fire extinguishing roller and the second fire extinguishing roller can be shortened.

In this case, it is preferable to form knurls (flat knurls 90, 91, 90B, 91B) on the outer circumferences of the first ridge and the second ridge.

With this configuration, the butts can be hooked on the lorlet and guided to the pressing start point where the pressing is started by being sandwiched between the outer peripheral surface of the first fire extinguishing roller and the outer peripheral surface of the second fire extinguishing roller. The time for the butts to stay on the 1 fire extinguishing roller and the 2nd fire extinguishing roller can be shortened.

In this case, it is preferable that the peripheral speeds of the first fire extinguishing roller and the second fire extinguishing roller are different.

With this configuration, the butts are rubbed against the rollers having a slow peripheral speed while being pressed against the outer peripheral surfaces of the first fire extinguishing roller and the outer peripheral surfaces of the second fire extinguishing roller, and the temperature of the butts is easily lowered. Therefore, the fire extinguishing efficiency can be improved.

In this case, a first dust sweeper (37) having a plurality of third convex portions (38) provided at predetermined intervals is arranged below the first fire extinguishing roller, and the first convex strip is the third convex portion. The first dust sweeper is arranged so as to enter with a predetermined gap between the two, and the first dust sweeper comes into contact with the butts attached to the outer peripheral surface of the first fire extinguishing roller to bring the outer periphery of the first fire extinguishing roller into contact with each other. The butts are peeled off from the surface, and a second dust sweeper (47) having a plurality of fourth convex portions (48) provided at predetermined intervals is arranged below the second fire extinguishing roller. The second dust sweeper is arranged so as to enter with a predetermined gap between the fourth convex portions, and the second dust sweeper comes into contact with the butts attached to the outer peripheral surface of the second fire extinguishing roller. It is better to peel the butts from the outer peripheral surface of the fire extinguishing roller.

With this configuration, the butts attached to the outer peripheral surfaces of the first fire extinguishing roller and the second fire extinguishing roller can be peeled off. Therefore, the fire-extinguishing butts rotate while sticking to the outer peripheral surfaces of the first fire-extinguishing roller and the second fire-extinguishing roller, and while overlapping with other newly introduced butts, they overlap with the outer peripheral surfaces of the first fire-extinguishing roller. It is possible to prevent the second fire extinguishing roller from being pressed against the outer peripheral surface. As a result, it is possible to prevent an increase in the rotational load, so that it is possible to prevent a stop due to an overload and a decrease in durability due to an overload.

In this case, it is preferable to provide a cigarette butt tank (60) for accommodating the butt fire extinguished by the first fire extinguishing roller and the second fire extinguishing roller.

According to the butts fire extinguishing device of the present invention, durability and fire extinguishing property can be improved while having a simple structure and a small number of parts and being compact.

It mainly has a gear 54. The rotational power generated by the motor 51 is transmitted to the rotating shaft 31 of the first fire extinguishing roller 30 by the coupling 52. The rotational force of the rotating shaft 31 of the first fire extinguishing roller 30 is transmitted to the second gear 54 fixed to the rotating shaft 41 of the second fire extinguishing roller 40 via the first gear 53. Therefore, if the motor 51 generates a clockwise rotational force when viewed from the right side, the first fire extinguishing roller 30 rotates clockwise and the second fire extinguishing roller rotates counterclockwise. That is, the first fire extinguishing roller 30 and the second fire extinguishing roller 40 are rotationally driven inwardly with respect to each other. A rotation sensor 45 for detecting the rotation of the second fire extinguishing roller 40 is arranged at the end of the rotating shaft 41 of the second fire extinguishing roller 40.

The gear ratio between the first gear 53 and the second gear 54 is set to, for example, 1: 2. Therefore, the peripheral speed of the second fire extinguishing roller 40 is half the peripheral speed of the first fire extinguishing roller 30. Due to the difference in peripheral speed between the first fire extinguishing roller 30 and the second fire extinguishing roller 40 in this way, the butts are rotated while being pressed against the outer peripheral surface of the first fire extinguishing roller 30 and the outer peripheral surface of the second fire extinguishing roller 40. Since it is easily rubbed against the slow second fire extinguishing roller 40 and the temperature of the butts is easily lowered, the fire extinguishing efficiency can be improved. The drive mechanism 50 configured as described above rotates the first fire extinguishing roller 30 at a peripheral speed of 27.0 mm / s and the second fire extinguishing roller 40 at a peripheral speed of 13.5 mm / s. In the present embodiment, the peripheral speed of the first fire extinguishing roller 30 is 27.0 mm / s and the peripheral speed of the second fire extinguishing roller 40 is 13.5 mm / s, but the first fire extinguishing roller 30 and the second fire extinguishing roller 30 The rollers 40 may have the same peripheral speed.

When the amount of butts stored in the butts tank 60 reaches a predetermined amount, the worker lowers the handle 67 in the direction of the arrow in FIG. 12A. Then, since the bottom lid 65 integrally formed with the handle 67 rotates diagonally backward and upward around the shaft portion 66, the opening on the lower surface of the storage box 61 is opened and stored in the butts tank 60. The butts that had been used fall into the collection bag 70, which will be described later. When the opening on the lower surface of the storage box 61 is closed with the bottom plate 63, the opening of the storage box 61 is only the portion of the fire extinguishing unit 20, so that the inflow of fresh air into the storage box 61 is blocked. ..

(Explanation of fire extinguishing process of cigarette butts fire extinguishing device 1)
The process of the butts fire extinguishing device 1 will be described with reference to FIGS. 9 and 13. FIG. 9 shows a cross-sectional view of the first fire extinguishing roller 30 and the second fire extinguishing roller 40 constituting the fire extinguishing unit 20. FIG. 13A is an explanatory view before the butts are sandwiched between the outer peripheral surface of the first fire extinguishing roller 30 and the outer peripheral surface of the second fire extinguishing roller 40 and pressed. FIG. 13B is an explanatory view while the butts are being pressed by being sandwiched between the outer peripheral surface of the first fire extinguishing roller 30 and the outer peripheral surface of the second fire extinguishing roller 40.

In the smoking booth 100, when the smoker finishes smoking and puts the cigarette butt into the ashtray lid 11d of the butt fire extinguishing device 1, the butt falls in the guide pipe 11e and is arranged directly under the guide pipe 11e. It falls on the first fire extinguishing roller 30 or the second fire extinguishing roller 40 of the fire extinguishing unit 20 (in FIG. 13A, it falls on the first fire extinguishing roller 30). When the butts fall in the induction line 11e, the passage sensor 24 detects the passage of the butts and transmits a signal to the control unit 80.

The control unit 80 receives a signal from the passage sensor 24 and operates the motor 51 of the drive mechanism 50. When the motor 51 of the drive mechanism 50 operates, the first fire extinguishing roller 30 rotates inward at a peripheral speed of 27.0 mm / s and the second fire extinguishing roller 40 rotates inward at a peripheral speed of 13.5 mm / s.

Next, when the first fire extinguishing roller 30 and the second fire extinguishing roller 40 are rotationally driven, as shown in FIG. 13 (a), the butts placed on the first fire extinguishing roller 30 are rotated by the rotation of the first fire extinguishing roller 30. It is guided to the pressing start point S (see FIG. 9). At this time, since the lateral grooves 34 and 44 parallel to the axial direction are formed on the outer peripheral surfaces of the first fire extinguishing roller 30 and the second fire extinguishing roller 40, the butts are dropped into the lateral grooves 34 and 44 and guided to the pressing start point S. It can be made easier.

Next, the butts guided to the pressing start point S are sandwiched between the outer peripheral surface of the first fire extinguishing roller 30 and the outer peripheral surface of the second fire extinguishing roller 40. At this time, the butts guided to the pressing start point S by the gaps between the first ridges 33 and the second ridges 43 and between the second ridges 43 and the first ridges 33 are the first fire extinguishing rollers. Since it can be easily sandwiched between the outer peripheral surface of the 30 and the outer peripheral surface of the second fire extinguishing roller 40, the fire extinguishing efficiency can be improved.

Next, the butts sandwiched between the outer peripheral surface of the first fire extinguishing roller 30 and the outer peripheral surface of the second fire extinguishing roller 40 are formed by rotating the first fire extinguishing roller 30 and the second fire extinguishing roller 40 to form an outer peripheral surface of the first fire extinguishing roller 30. By gradually narrowing the gap between the outer peripheral surfaces of the second fire extinguishing roller 40, the second fire extinguishing roller 40 moves downward while being pressed (see FIG. 13B).

When the butts are pressed against the outer peripheral surfaces of the first fire extinguishing roller 30 and the outer peripheral surfaces of the second fire extinguishing roller 40, the heat of the butts is taken away by the first fire extinguishing roller 30 and the second fire extinguishing roller 40, and the temperature drops. , The outer peripheral surface of the first fire extinguishing roller 30 and the outer peripheral surface of the second fire extinguishing roller 40 block the supply of oxygen to the butts, so that the fire is extinguished. At this time, the first ridges 33 are arranged so as to enter the second ridges 43 with a predetermined gap, and the second ridges 43 have a predetermined gap between the first ridges 33. The contact area when the butts are pressed against the outer peripheral surface of the first fire extinguishing roller 30 and the outer peripheral surface of the second fire extinguishing roller 40 can be increased. Therefore, the temperature of the butts can be easily lowered and the supply of oxygen to the butts can be easily cut off, so that the fire extinguishing efficiency can be improved.

Further, when pressed against the outer peripheral surface of the first fire extinguishing roller 30 and the outer peripheral surface of the second fire extinguishing roller 40, as described above, the drive mechanism 50 moves the first fire extinguishing roller 30 at a peripheral speed of 27.0 mm / s. Since the second fire extinguishing roller 40 is rotated at a peripheral speed of 13.5 mm / s, the butts are pressed against the outer peripheral surface of the first fire extinguishing roller 30 and the outer peripheral surface of the second fire extinguishing roller 40. The fire extinguishing efficiency can be improved because the temperature of the butts is easily lowered by being rubbed against the second fire extinguishing roller 40 having a slow peripheral speed.

Next, the butts pressed against the outer peripheral surface of the first fire extinguishing roller 30 and the outer peripheral surface of the second fire extinguishing roller 40 are extinguished by rotation of the first fire extinguishing roller 30 and the second fire extinguishing roller 40, and the pressing end point F (FIG. 9) is moved. When the butts are released from pressure on the outer peripheral surfaces of the first fire extinguishing roller 30 and the outer peripheral surfaces of the second fire extinguishing roller 40, they fall into the butts tank 60 due to gravity.

In this way, since the butts are extinguished by using two rollers (first fire extinguishing roller 30 and second fire extinguishing roller 40) arranged in parallel, the dimension in the height direction can be reduced. Further, since the first fire extinguishing roller 30 and the second fire extinguishing roller 40 do not need to be elastically deformed and can be formed of metal, heat absorption and fire extinguishing can be promoted and durability can be improved.

At this time, although the butts were released from pressing on the outer peripheral surface of the first fire extinguishing roller 30 and the outer peripheral surface of the second fire extinguishing roller 40, the outer peripheral surface of the first fire extinguishing roller 30 or the second fire extinguishing roller 40 It may remain stuck to the outer peripheral surface of the. Even if the butts are attached to the outer peripheral surface of the first fire extinguishing roller 30 or the outer peripheral surface of the second fire extinguishing roller 40, the first fire extinguishing roller 30 and the second fire extinguishing roller 40 rotate, and the butts become the first. 1 From the outer peripheral surface of the first fire extinguishing roller 30 or the outer peripheral surface of the second fire extinguishing roller 40 by contacting with the third convex portion 38 of the dust sweeper 37 or the fourth convex portion 48 of the second dust sweeper 47. It peels off and falls into the butts tank 60.

This completes the fire extinguishing process for the butts of the butts fire extinguishing device 1.

As described above, according to the cigarette butt fire extinguishing device 1 of the present invention, it is possible to improve durability and fire extinguishing property while having a simple structure and a small number of parts and being compact.
