  However, in a structure in which a cigarette is sandwiched between two rotating belts and crushed to extinguish the fire, even if the cigarette can be crushed, it cannot be surely extinguished. In other words, even if a cigarette is sandwiched between two belts, the fire may remain passing through the belt. In addition, when a plurality of cigarettes overlap and enter between the belts, there is a problem that the belts pass through the belts without being extinguished depending on the degree of overlap. Furthermore, if foreign matter other than tobacco is mixed in, it may cause damage to the belt.

  The objective of this invention is providing the fire extinguishing part structure and automatic fire-extinguishing ashtray which can extinguish a cigarette automatically and reliably.

  In order to solve the above problems, a fire extinguishing unit structure for extinguishing a cigarette according to the present invention includes a first elastic member, a second elastic member, and a drive unit. The first elastic member is hung on a first shaft and a second shaft provided in parallel to each other, has heat resistance against tobacco fire, and rotates at a first rotation speed. The second elastic member is hung on a third shaft and a fourth shaft provided in parallel to each other, has heat resistance against tobacco fire, and rotates at a second rotational speed while contacting the first elastic member in the contact region. . The drive unit rotates the first elastic member and the second elastic member. A line connecting the central axis of the first shaft and the central axis of the second shaft is the first central axis, a line connecting the central axis of the third shaft and the central axis of the fourth shaft is the second central axis, and the first central axis When the line orthogonal to the central axis of the first shaft is the first orthogonal line, the first central axis and the second central axis are parallel to each other and not parallel to the vertical direction. Further, the central axis of the third shaft is provided at a position shifted from the first orthogonal line.

  According to such a configuration, the tobacco is sandwiched and crushed by the contact region between the rotating first elastic member and the second elastic member. At this time, the degree of adhesion to the cigarette can be increased by the elasticity of the first elastic member and the second elastic member. Further, the cigarette is conveyed in an oblique direction while being sandwiched between contact areas between the first elastic member and the second elastic member. Therefore, the frictional force that the tobacco receives from both elastic members can be increased as compared with the case where the tobacco is conveyed in the vertical direction.

  In the fire extinguishing part structure of the present invention, the contact region may be provided in an S shape when viewed in the direction along the central axis of the first shaft. According to such a structure, the tobacco pinched | interposed in the contact area of a 1st elastic member and a 2nd elastic member will be crushed for a long time in a contact area. Therefore, the cigarette can be reliably crushed and extinguished while saving space.

  In the fire extinguishing unit structure of the present invention, a movable plate provided above the contact area and a shaft with a protrusion provided at a position facing the movable plate are further provided, and the movable plate is disposed near the contact start port of the contact area. You may make it rock | fluctuate in. Thereby, for example, even when a plurality of cigarettes are thrown in, the cigarettes are separated by swinging the movable plate, and the cigarettes are hooked by the projections of the shafts with projections, so that the first elastic member and the second elastic member It becomes possible to send in between. For this reason, it is possible to suppress the clogging of the inserted cigarette and to perform the fire extinguishing surely.

  In the fire extinguishing unit structure of the present invention, a protrusion that contacts the movable plate by rotation of the first elastic member may be provided on the outer periphery of the first elastic member. Accordingly, the movable plate swings when the protrusion comes into contact with the movable plate by the rotation of the first elastic member.

  The fire extinguishing part structure of the present invention may further include a first roller and a second roller that are provided below the first elastic member and the second elastic member and rotate in opposite directions while being in contact with each other. According to such a configuration, the cigarette that has passed through the contact area between the first elastic member and the second elastic member is sandwiched between the first roller and the second roller, and more reliable fire extinguishing can be performed. .

  In the fire extinguishing part structure of the present invention, the second elastic member may be softer than the first elastic member. In such a configuration, while supporting the cigarette with the first elastic member, the soft second elastic member is pressed so as to firmly wrap the cigarette so that the fire can be reliably extinguished.

  The automatic fire extinguishing ashtray of the present invention includes a charging part having a charging port for cigarettes, a fire extinguishing part structure disposed below the charging part, and a butt collection part disposed below the fire extinguishing part structure. As this fire extinguishing part structure, any one of the above-mentioned fire extinguishing part structures of the present invention is applied. According to such a structure, the cigarette thrown in from the insertion port can be extinguished automatically and reliably by the fire extinguishing part structure, and can be accommodated in the butt collection part.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the following description, the same members are denoted by the same reference numerals, and the description of the members once described is omitted as appropriate.

(First embodiment)
As shown in the perspective view of FIG. 1, the automatic fire extinguishing ashtray 1 according to the present embodiment includes a charging unit 2 having a charging port 2 </ b> A for tobacco TB, a fire-extinguishing unit structure 3 disposed below the charging unit 2, A butt collection part 4 disposed below the fire extinguishing part structure 3. The automatic fire extinguishing ashtray 1 is a device that automatically extinguishes the fire of the tobacco TB introduced into the insertion port 2 </ b> A by the fire extinguishing part structure 3 and accommodates it in the butts collection part 4.

  In the side view of FIG. 2, the internal structure of the automatic fire ashtray 1 as seen from the side is shown. A hopper 22 is provided in the charging port 2A of the charging unit 2. The tobacco TB introduced from the insertion port 2A falls along the inclined plate of the hopper 22 and is sent into the fire extinguishing unit structure 3 below.

  The fire extinguishing unit structure 3 includes a first elastic member 10, a second elastic member 20, and a drive unit 30. The first elastic member 10 and the second elastic member 20 have heat resistance against the fire of the tobacco TB. For the first elastic member 10 and the second elastic member 20, for example, heat resistant silicone rubber of about 0 ° C. to 200 ° C. is used. Each of the first elastic member 10 and the second elastic member 20 is provided in a cylindrical shape, and rotates while contacting each other in the contact area CA. Thereby, the inserted tobacco TB is sandwiched between the first elastic member 10 and the second elastic member 20 in the contact area CA, and is crushed while being conveyed.

  The first elastic member 10 rotates at the first rotation speed, and the second elastic member 20 rotates at the second rotation speed in the direction opposite to the first elastic member 10. The first rotation speed is desirably different from the second rotation speed. By providing such a difference in rotational speed, a displacement between the first elastic member 10 and the second elastic member 20 occurs in the contact area CA, and the cigarette TB can be crushed and pressed. .

  A first roller 15 and a second roller 16 may be provided below the first elastic member 10 and the second elastic member 20. The first roller 15 and the second roller 16 have fire resistance against the fire of the tobacco TB. For the first roller 15 and the second roller 16, for example, heat resistant silicone rubber of about 0 ° C. to 200 ° C. is used.

  The first roller 15 and the second roller 16 rotate in opposite directions while being in contact with each other. The tobacco TB crushed by the first elastic member 10 and the second elastic member 20 is sandwiched between the first roller 15 and the second roller 16. As a result, even if the first elastic member 10 and the second elastic member 20 cannot extinguish the cigarette TB, the cigarette TB can be extinguished reliably.

  The drive unit 30 is a mechanism part that rotates the first elastic member 10 and the second elastic member 20 by a motor or the like. Details of the drive unit 30 will be described later.

Next, the configuration of the first elastic member 10 and the second elastic member 20 will be described in detail.
As shown in the perspective view of FIG. 3A, the first elastic member 10 has a predetermined width in a direction orthogonal to the traveling direction by rotation. The first elastic member 10 is hooked on the first shaft ST1 and the second shaft ST2 that are parallel to each other and extend in the width direction, and rotates in an oval shape.

  The second elastic member 20 is hung on a third shaft ST3 and a fourth shaft ST4 extending in the width direction and parallel to each other. The second elastic member 20 faces the first elastic member 10 and is provided in an oval shape so as to rotate in a direction opposite to the first elastic member 10. Thus, a contact area CA is provided between the first elastic member 10 and the second elastic member 20 facing each other. As the first elastic member 10 and the second elastic member 20 rotate in the reverse direction, the tobacco TB is sandwiched between the contact areas CA and pressed while being sent out to extinguish the fire.

  The second elastic member 20 is desirably softer than the first elastic member 10. Since the second elastic member 20 is softer than the first elastic member 10, the second elastic member 20 can wrap the periphery of the tobacco TB with high adhesion while the first elastic member 10 supports the tobacco TB. Thereby, cigarette TB can be pressed firmly and a reliable fire extinguishing can be performed.

  As shown in the side view of FIG. 3B, the traveling direction of the first elastic member 10 and the second elastic member 20 in the contact area CA (hereinafter, also simply referred to as “the traveling direction in the contact area CA”). Are provided non-parallel to the vertical direction. That is, a line connecting the central axis of the first shaft ST1 and the central axis of the second shaft ST2 is the first central axis CL1, and a line connecting the central axis of the third shaft ST3 and the central axis of the fourth shaft ST4 is the second. In the case of the central axis CL2, the first central axis CL1 and the second central axis CL2 are parallel to each other and non-parallel (oblique) to the vertical direction.

  Thus, since the traveling direction in the contact area CA is not parallel to the vertical direction, the tobacco TB is sandwiched between the contact areas CA between the first elastic member 10 and the second elastic member 20. It is conveyed in an oblique direction. Here, when the traveling direction in the contact area CA is vertical, the tobacco TB sandwiched between the contact areas CA is easily sent downward. On the other hand, when the traveling direction in the contact area CA is inclined as in the present embodiment, the friction that the tobacco TB receives from the first elastic member 10 and the second elastic member 20 as compared with the case where the traveling direction is vertical. Can increase power. Moreover, the contact area CA can be made long even in a space-saving manner in the housing of the automatic fire extinguishing ashtray 1. Thereby, reliable fire extinguishing is realized.

  Further, in the present embodiment, when a line orthogonal to the first central axis CL1 and the central axis of the first shaft ST1 is a first orthogonal line CR1, the central axis of the third shaft ST3 is from above the first orthogonal line CR1. It is provided at a deviated position. As a result, the first elastic member 10 and the second elastic member 20 are disposed in a positional relationship as seen in the direction along the first orthogonal line CR1.

  According to such a positional relationship, the first shaft ST1 and the third shaft ST3 do not overlap in the direction along the first orthogonal line CR1, and the interval between the first elastic member 10 and the second elastic member 20 is set. The degree of freedom increases. In the present embodiment, the second shaft ST2 and the fourth shaft ST4 do not overlap in the direction along the first orthogonal line CR1. Thereby, the freedom degree of the setting of the space | interval of the 1st elastic member 10 and the 2nd elastic member 20 increases further.

  For example, the travel route viewed from the side of the contact area CA may be curved (for example, S-shaped) by setting the thickness and the interval between the first elastic member 10 and the second elastic member 20. Thereby, with the increase in the adhesion force in the contact area CA, the path length of the contact area CA becomes longer, and the time for extinguishing the tobacco TB can be lengthened.

  In the present embodiment, the position of the second shaft ST2 is between the third shaft ST3 and the fourth shaft ST4 in the direction along the first orthogonal line CR1 (hereinafter simply referred to as “orthogonal line direction”). The position of the third shaft ST3 is provided between the first shaft ST1 and the second shaft ST2. The first elastic member 10 and the second elastic member 20 are in contact between the second shaft ST2 and the third shaft ST3 when viewed in the orthogonal direction. Therefore, the contact area CA is provided between the second shaft ST2 and the third shaft ST3 when viewed in the orthogonal direction.

  In the contact area CA, the first elastic member 10 and the second elastic member 20 are in contact with each other so as to be pressed against each other, so that the travel route in the contact area CA is provided in a curved shape (for example, an S shape). Will be. In the present embodiment, the travel route of the contact area CA can be curved without using a separate roller or the like only by the positional relationship between the first elastic member 10 and the second elastic member 20 as described above.

Next, details of the drive unit 30 will be described.
As illustrated in the side view of FIG. 4, the drive unit 30 includes, for example, a motor 31, a chain 32, and a plurality of gears 33 (including gears 331, 332, 333, and 334). The motor 31 is disposed in the space above the second elastic member 20. In the present embodiment, since the first elastic member 10 and the second elastic member 20 are arranged obliquely, a space is formed above the second elastic member 20. Space can be saved by arranging the motor 31 in this space.

  The gear 331 is fixed to the end of the first shaft ST1 on which the first elastic member 10 is engaged, and the gear 332 is fixed to the end of the third shaft ST3 on which the second elastic member 20 is engaged. The gear 333 is fixed to the fifth shaft ST5 that supports the first roller 15, and the gear 334 is fixed to the sixth shaft ST6 that supports the second roller 16. The rotation of the motor 31 is transmitted to the first elastic member 10 and the second elastic member 20 as well as the first roller 15 and the second roller 16 via the chain 32 and the plurality of gears 33.

  Here, the rotational speed of the first elastic member 10 (first rotational speed) and the rotational speed of the second elastic member 20 (second rotational speed) according to the ratio between the number of teeth of the gear 331 and the number of teeth of the gear 332. The ratio is determined. In the present embodiment, the first rotation speed of the first elastic member 10 is made different from the second rotation speed of the second elastic member 20. By providing a difference in rotation speed, a shift occurs in the contact area CA between the first elastic member 10 and the second elastic member 20, and the tobacco TB can be crushed while rubbing against each other in the contact area CA.

  In the present embodiment, the rotation time per rotation of the first elastic member 10 and the second elastic member 20 is set between about 90 seconds and 130 seconds. Moreover, the time for the tobacco TB to pass through the contact area CA is about 40 seconds to 60 seconds. As a result, a sufficient crushing time is obtained while the tobacco TB passes through the contact area CA, and the fire can be reliably extinguished.

  Note that a sensor may be provided in the insertion port 2A, and the motor 31 may be rotated for a certain period of time when the sensor detects that the tobacco TB has been input. Thereby, the rotation of the motor 31 can be stopped for an unnecessary time, and power saving can be achieved. In this embodiment, the rotation of the motor 31 is transmitted as the drive unit 30 by the chain 32 and the gear 33. However, a belt and a pulley may be used instead of the chain 32 and the gear 33, and only the gear 33 is used. A driving force may be transmitted. Further, the first elastic member 10 and the second elastic member 20, and the first roller 15 and the second roller 16 may be directly rotated by the motor 31.

Next, how the tobacco TB is extinguished will be described.
As shown in the schematic diagram of FIG. 5, the tobacco TB inserted from the insertion port 2 </ b> A is sent to the lower fire extinguishing unit structure 3. The cigarette TB is put in a contact area CA provided between the first elastic member 10 and the second elastic member 20 that rotate reversely to each other, and is sandwiched between the first elastic member 10 and the second elastic member 20. To advance through the contact area CA.

  In the contact area CA, the tobacco TB is crushed while being rubbed due to the difference between the rotation speed of the first elastic member 10 and the rotation speed of the second elastic member 20. The tobacco TB is extinguished while the tobacco TB passes through the contact area CA. Then, the tobacco TB that has escaped from the contact area CA is further crushed between the lower first roller 15 and the second roller 16. Then, the tobacco TB discharged from between the first roller 15 and the second roller 16 is accommodated in the lower butt collection unit 4.

  6A and 6B show a state in which the tobacco TB is sandwiched as viewed from the front in the traveling direction in the contact area CA. As illustrated in FIG. 6A, when the tobacco TB is in the contact area CA, the tobacco TB is sandwiched and pressed between the first elastic member 10 and the second elastic member 20. The tobacco TB is crushed while being surrounded by the first elastic member 10 and the second elastic member 20. In the present embodiment, since the adhesion between the tobacco TB and the first elastic member 10 and the second elastic member 20 is high, reliable fire extinguishing is performed.

  In addition, the introduced tobacco TB enters the contact area CA at various angles. Regardless of the angle at which the tobacco TB enters, the first elastic member 10 and the second elastic member 20 in contact with the tobacco TB are crushed and reliable fire extinguishing is performed.

  Furthermore, as shown in FIG. 6B, a plurality of cigarettes TB may enter the contact area CA in an overlapping manner. Although the overlapping state of the tobacco TB is various, in this embodiment, portions of the first elastic member 10 and the second elastic member 20 that are in contact with the tobacco TB are crushed so as to surround the tobacco TB. Therefore, even if a plurality of cigarettes TB are overlapped, it is possible to surely extinguish each cigarette TB.

  Even when foreign matter other than the tobacco TB (for example, a hard object such as a wood screw or a nail) is mixed, damage can be avoided by elastic deformation of the first elastic member 10 and the second elastic member 20. For example, in a configuration in which the cigarette TB is held between two rotating metal belts to extinguish the fire, there is a possibility that the metal belt may be damaged or broken if a hard object such as a nail is mixed. In the present embodiment, even if such foreign matter is mixed, the first elastic member 10 and the second elastic member 20 can be prevented from being damaged or damaged, and long-term reliability can be improved.

(Another example of the first embodiment)
Next, another example of the first embodiment will be described.
As shown in the side view of FIG. 7A, the fire extinguishing unit structure 3 according to another example further includes a movable plate 40 provided on the upper side of the contact area CA. The movable plate 40 is provided to swing near the contact start port of the contact area CA.

  For example, a plurality of protrusions 101 are provided on the outer peripheral surface of the first elastic member 10. The protrusion 101 moves with the rotation of the first elastic member 10. When the protrusion 101 contacts the movable plate 40, the movable plate 40 is pushed up by the protrusion 101. On the other hand, when the contact of the protrusion 101 is eliminated, the movable plate 40 is returned downward. By the rotation of the first elastic member 10, the plurality of protrusions 101 sequentially come into contact with the movable plate 40. By repeating this, the movable plate 40 swings.

  The movable plate 40 is provided above the contact area CA and swings in the vicinity of the contact start port. For example, even when a plurality of cigarettes TB are inserted, the movable plate 40 swings the tobacco TB. Thus, it is possible to reliably feed the space between the first elastic member 10 and the second elastic member 20 (contact area CA). For this reason, it is possible to suppress the clogging of the inserted tobacco TB and to perform the fire extinguishing surely.

  Further, by moving the projection 101 with the rotation of the first elastic member 10, the tobacco TB is easily hooked by the projection 101 and guided to the contact area CA. That is, even when the movement of the tobacco TB stops near the contact start port of the contact area CA, or even when a plurality of tobacco TBs are overlapped and clogged, they are hooked by the protrusions 101 and the tobacco TB is reliably transferred to the contact area CA. Can be sent in.

  Note that the movable plate 40 may be configured to swing by transmitting the driving force of the motor 31 via a mechanism such as a cam, in addition to swinging by contact with the protrusion 101.

  Moreover, in the fire extinguishing part structure 3 according to another example, the shaft 18 with a protrusion may be provided at a position facing the movable plate 40. The projecting shaft 18 has a plurality of projecting portions 18a extending radially around the shaft. A driving force is transmitted from the driving unit 30 to the shaft 18 with protrusions. Thereby, the shaft 18 with protrusions rotates in the same direction as the first elastic member 10.

  With such a configuration, when a plurality of cigarettes TB are thrown in, the cigarettes TB held by the movable plate 40 are hooked by the protruding portions 18a of the shaft 18 with the protrusions and dropped one by one into the contact area CA. become. Therefore, even if a plurality of cigarettes TB overlap between the movable plate 40 and the shaft 18 with projections, the tobacco TB is surely guided to the contact area CA one by one by the action of both the movable plate 40 and the shaft 18 with projections. The clogging due to the overlap of the tobacco TB can be suppressed and the fire can be surely extinguished.

  FIG. 7B is a perspective view showing another example of the first shaft ST1. The first shaft ST1 has a portion formed, for example, in a star shape in the axial direction. The first shaft ST <b> 1 is a drive side shaft that applies a rotational force to the first elastic member 10. Since each star-shaped tip of the first shaft ST1 bites into the inner peripheral surface of the first elastic member 10, the adhesion between the first shaft ST1 and the first elastic member 10 is enhanced. Therefore, the slip between the first shaft ST1 and the first elastic member 10 is suppressed, and the rotational force of the first shaft ST1 can be reliably transmitted to the first elastic member 10.

  Note that the third shaft ST3 may also have a star-shaped portion like the first shaft ST1. Further, the second shaft ST2 and the fourth shaft ST4, which are driven shafts, may have a star-shaped portion as necessary.

(Second Embodiment)
Next, the second embodiment will be described.
The schematic diagram of FIG. 8 illustrates a configuration example of a transport type recovery apparatus 1B according to the second embodiment. The transport type recovery device 1 </ b> B is a device that transports the tobacco TB by the transport belt 50 and sends it to the fire extinguishing unit structure 3. The fire extinguishing unit structure 3 is disposed adjacent to the downstream side of the transport belt 50. In the transport type recovery apparatus 1B, the smoked tobacco TB is sent onto the transport belt 50 from the insertion port 60. Then, the tobacco TB is sequentially sent to the fire extinguishing unit structure 3 by the transport belt 50. The fire extinguishing part structure 3 described above is applied to the fire extinguishing part structure 3. The tobacco TB transported by the transport belt 50 is surely extinguished by the fire extinguishing unit structure 3 and accommodated in the butts collection unit 4.

  In such a transport type recovery apparatus 1B, the transport belt 50 is laid out at a predetermined position in the store, for example. In addition, input ports 60 are provided at a plurality of locations in the store. As a result, the tobacco TB introduced from the plurality of introduction ports 60 is conveyed by the conveyance belt 50 and extinguished all at once by the fire extinguishing unit structure 3.

  As described above, according to the fire extinguishing unit structure 3 and the automatic fire extinguishing ashtray 1 according to the present embodiment, it is possible to automatically and reliably extinguish the tobacco TB.

  Although the present embodiment and other examples have been described above, the present invention is not limited to these examples. For example, those in which those skilled in the art appropriately added, deleted, and changed the design of the above-described embodiments or other examples, or combinations of the features of the embodiments as appropriate, are also included in the present invention. As long as the gist is provided, it is included in the scope of the present invention.

In the above, silicone rubber is used as the material of the elastic member, but other materials can be selected. For example, if fluororubber is used, the heat resistant temperature is higher, and further durability of the elastic member can be realized.
