DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cigarette butt collecting apparatus for automatically collecting cigarette butts from a large number of ashtrays arranged in a pachinko machine train and the like, and a collecting line used for the apparatus.

[0002]

2. Description of the Related Art Conventionally, in a pachinko game hall, an ashtray is attached to each pachinko machine stand. When an ashtray is attached to each pachinko machine, the capacity is small in terms of space, so that several cigarette butts fill up, and the unburned smoke often pollutes the indoor air. Also, in addition to tobacco, wrapping paper such as gum may be put together, which is not preferable from the viewpoint of fire prevention. For this reason, in pachinko game halls, etc., where many ashtrays are provided, in order to prevent indoor contamination and fire, etc., all the ashtrays should be cleaned frequently, and ash, cigarette butts, paper waste, etc. should be removed quickly. It must be removed and always kept in a clean and safe indoor environment.

[0003] Therefore, since many ashtrays of this kind are arranged in a straight line at regular intervals, a conveying means such as a vacuum pipe, a belt conveyor or a scraping plate is provided below the area where the ashtray is arranged. A device has been proposed for automatically collecting and cleaning cigarette butts falling from all ashtrays. 2. Description of the Related Art Conventionally, a cigarette butt collecting apparatus using a scraping method is disclosed in, for example, Japanese Patent Application Laid-Open No. 2-1.
There is a prior art described in 6962. The means for transferring butts and the like in this prior art recovery device is described as "an endless cable 8 consisting of a chain wound around a chain gear 10 disposed at four corners in the guide / recovery pipe 4 with their shafts oriented vertically. And a plurality of scraping plates 9 "provided at appropriate places on the endless cable 8." The bottom surface of the conduit 4 is flat.

[0004]

By the way, in the above-mentioned prior art, a normal roller chain is used as the endless rope 8 wound around the chain gear as the transfer means, and the flat scraper 9 is mounted on the scraper 9. In addition, the use of the collection / recovery conduit 4 having a horizontal bottom surface has the following problems. In other words, a large amount of tobacco smoke is always present in the collecting and collecting pipeline communicating with a large number of ashtrays, since the dropped butts are temporarily stored therein. On the other hand, since the roller chain is formed by rotatably connecting a number of rings and requires oil supply, the rings and sprockets are stuck to the rings and sprockets in the guide / recovery pipe, so that they cannot operate smoothly. In particular, when the drive is stopped, the dust is hardened, and the next start is extremely difficult.

Further, the roller chain needs to be guided by a large number of sprockets, so that noise is increased. In addition, since the chain gear is arranged with the shaft oriented in the vertical direction, the roller chain falls off during traveling. And there is a problem that smooth running is difficult. Further, since the bottom surface of the conduit is formed in a horizontal plane, there is a possibility that the scraper will overflow from the side surface of the scraper plate when the butts are scraped off. If a large scraping plate does not cause the butts or the like to overflow from the side, there is a problem that the height (depth) of the guide / recovery pipe becomes large and the knee hits and gets in the way.

SUMMARY OF THE INVENTION The present invention has been made in view of the above point, and a method of scraping cigarette butts and the like dropped from a large number of ashtrays and recovering the cigarette butts with a small influence of cigarette dust and running smoothly without noise. It is an object of the present invention to provide a cigarette butt and the like collection device capable of reliably collecting butts and the like, and a collection line used for the device.

[0007]

The present invention has the following configuration to achieve the above object. That is, the cigarette butt collecting apparatus of the present invention has a large number of ashtrays attached at appropriate intervals, and is connected so that the butts and the like from these ashtrays can be dropped into a collecting pipe. A ladder chain in which a driving sprocket driven by a driving device and a rotatable driven pulley are disposed inside a recovery pipe, and a scraping plate is attached at an appropriate interval between the driving sprocket and the driven pulley. The drive sprocket is guided on both sides of the sprocket body by a drop-off prevention ring having a circumferential surface inclined to the stepped side and a stepped side, and guiding the ladder chain to the groove formed by the stepped portion. The driven pulley has a groove formed in the center of the peripheral surface, and both sides of the peripheral surface are formed with inwardly inclined surfaces, and the scraping plate is turned inside the recovery pipe and moves. , Wherein the conveying scraped butts like that accumulated on the bottom of the recovery pipe when horizontally moving the bottom of the recovery pipe.

[0008]

The rudder chain does not require refueling, so it is not affected by tobacco tarnish and can run smoothly. Since the drive sprocket and the driven pulley have inwardly inclined surfaces on both sides of the peripheral surface, the ladder chain is always restricted to the center. Therefore, the inclined surface serves to prevent the ladder chain from falling off. On the other hand, since the collecting pipe has a shape in which the bottom is narrowed, butts and the like can be collected in a row without being scattered, and the hit of the knee can be released.
