[0003] The tobacco leaves of this cigarette roll such as cigarettes are agricultural products, and their properties are not exactly constant. When producing the above cigarette rolls, the cigarette is produced at a predetermined ratio in accordance with the number of cigarettes manufactured. A number of samples are taken out, the samples are smoked by a smoking machine, and the components contained in the smoke are analyzed. Therefore, as the number of manufactured cigarette turns increases, the number of turns to be analyzed also increases.

[0004] The smoking machine is provided with a plurality of smoking ports, and a cigarette or other cigarette winding is attached to these smoking ports via a holder. Then, while igniting the mounted winding, the smoking machine inhales air through the tobacco winding in a predetermined pattern. A Cambridge filter is provided inside the holder to collect components such as tar. Further, other components of the smoke inhaled into the smoking machine are analyzed by the analyzer.

Heretofore, mounting of a cigarette or a holder, ignition, fire extinguishing, elimination of butts, etc. on the smoking machine have all been performed manually by an inspector. Therefore, when the number of windings to be inspected increases as described above, these simple operations must be repeated for a long time, and the burden on the inspector increases.

In order to solve such a problem, an attempt has been made to develop a device for automatically mounting the above-mentioned winding, igniting, extinguishing, and removing butts by a robot. By the way, in the inspection as described above, after the cigarette is burned for a predetermined length, the burning portion at the tip of the tobacco is cut,
It is specified that the smoke in the rest of the cigarette is also suctioned and analyzed. Therefore, in order to automatically inspect such a cigarette winding, the cutting section of the tobacco winding must also be automatically cut.

[0007] Although the cigarettes such as cigarettes are relatively soft as a whole, the tobacco leaves and wrapping paper are fibrous. Blade must be pressed.

However, as described above, the cigarette winding is soft as a whole, and the cigarette winding is merely inserted into the holder attached to the smoking mouth, so that the burning of the tip Due to the strong force at the time of cutting the part with the cutter blade, the cigarette winding is crushed or the part inserted into the holder is displaced, so that there is a problem that accurate and reliable cutting cannot be performed.

[0009]

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and has been developed for use in an automatic smoking machine for automatically mounting, igniting, extinguishing, and removing a cigarette butt. It is intended to provide a cutting mechanism capable of surely cutting off the combustion portion at the tip of the device and stopping the combustion.

The present invention includes, for example, an automatic winding / unloading device, and a cutting mechanism is detachably mounted on the automatic winding / unloading device. This cutting mechanism is provided with a pair of openable and closable members that are movable in the direction of contacting and separating from each other. And
These cutting blades combine two symmetrical right-triangular blades, and the opposing tips form a chevron, for example, an isosceles triangle, and the tops oppose each other. Also,
These cutting blades are arranged so as to be shifted from each other in the thickness direction, and when the opening and closing members are moved so as to approach each other, the distal ends of these cutting blades are configured to overlap in the thickness direction. I have.

[0011]

The cigarette to be cut is positioned between the pair of opening / closing members, and the opening / closing members move in directions approaching each other. And since the tip of the above-mentioned cutting blade is formed in the shape of a chevron, first, the top of this chevron pierces the side of the tobacco winding, and the tobacco is cut by the blades on both slopes on both sides of the cutting blade of this chevron Cut the roll paper while cutting open. The tops of the mountain-shaped cutting blades face each other. Therefore, when cutting the cigarette roll with such a cutting blade, almost no force is generated to rotate the cigarette roll. Further, since the wrapping paper is cut so as to be cut open on both sides in this manner, the force required for this cutting is small, and the wrapping of the cigarette does not collapse or deform. Therefore, reliable cutting becomes possible.

FIG. 5 shows the gripping mechanism 35 of the work hand 33 described above. The gripping mechanism 35 includes a pair of fingers 7.
1 and these fingers 71
Are opened and closed while maintaining a parallel state with each other, and the cigarette is gripped.

An optical detector, for example, a light source 73 such as an LED, and a photodiode 74 are provided at the tips of the fingers 71. These are attached to the fingers 71 and face each other. Therefore, the light emitted from the light source 73 is received by the photodiode 74. Therefore, if another object, that is, the cigarette winding 4 exists between the fingers 71, that is, between the light source 73 and the photodiode 74, the light from the light source 73 is blocked.

Then, the robot 31 attaches the cigarette roll 4 to the smoking opening 2 and then sets the finger 7
1 in an open state, and the tobacco winding 4 attached as shown in FIG.

In this case, the movement position of the ignition mechanism 37 is controlled based on the position information of the leading end of the cigarette winding 4. Therefore, the heater surely comes into contact with the leading end of the cigarette winding 4 and can reliably ignite. Further, it is possible to prevent the heater 4 from hitting the leading end of the cigarette roll 4 too strongly, and thereby preventing the cigarette roll 4 from shifting.

Further, the combustion detecting mechanism 41 can be set at a position corresponding to the burning length of the cigarette roll 4 with reference to the position of the leading end of the cigarette roll 4 as described above. The burning position of the cigarette winding 4 is detected by the above-described burning position detecting mechanism 41. When the cigarette winding 4 burns from the above-described tip position to a position of a predetermined length, the above-described cutting mechanism is used. The combustion portion of the cigarette winding is cut by 36, and the combustion is stopped.

Further, for example, two guide rods 83 are provided below these opening / closing members 82. These guide rods 83 penetrate the sliding members through the sliding bush 85 provided on the opening / closing member 82, and these opening / closing members 82
Guides you to move accurately. Further, a compression coil spring 84 is interposed between these opening / closing members 82 and urges these opening / closing members 82 in a direction away from each other.

A pair of cutting blades 86 are attached to the front ends of these opening / closing members 82. In addition, these cutting blades 86 are attached by bolts 87,
By removing these bolts 87, they can be easily replaced. These cutting blades 86 have a thin plate shape and are protruded so as to face each other. Further, these cutting blades 86 are formed by combining two symmetrical right-angled triangular blades, and their opposing tips form a mountain shape, for example, an isosceles triangle, and the blade portions are formed on the slopes on both sides thereof. And these mountain-shaped cut parts 86 are arrange | positioned so that the top part may mutually oppose. Further, these cutting blades 86 are arranged so as to be displaced in the thickness direction by the thickness of the cutting blades. Therefore, when the opening / closing members 82 are moved closer to each other, these angled cutting blades are used. The distal end portion 86 is configured to overlap in the thickness direction.

The cutting mechanism 36 configured as described above
The opening / closing member 82 is moved to the position of the cigarette roll 4 to be cut in the separated open state, and these opening / closing members 8 are moved.
The cigarette winding 4 is located between the two. Further, the cutting mechanism 36 is moved in the axial direction of the cigarette roll 4, and the position of the cutting blade 86 is set at a position where the cigarette roll is to be cut, that is, slightly behind the burning portion at the leading end of the cigarette roll. Is located.

Then, by the opening / closing drive mechanism described above,
The above-mentioned check members 81 are moved in a direction approaching each other, and at the same time, the opening / closing members 82 are moved in a direction approaching each other. Thereby, the above-mentioned cutting teeth 86 approach,
As shown in FIG. 8, the tops of these cutting blades 86 pierce both side surfaces of the cigarette roll 4, and when the cutting blades 86 are further approached, the blades on the slopes on both sides of the cutting blades 86 cause this. The cigarette roll 4 is cut open on both sides. When the cutting blades 86 are further advanced, the tips of the cutting blades 86 overlap in the plate thickness direction as shown in FIG. 9, and the cutting blades 86 are further predecessors to cut the cigarette winding. Then, the burning of the tobacco winding 4 is stopped by cutting the burning portion at the tip of the tobacco winding 4 in this way.

It should be noted that, even after the end of the cigarette roll 4 is cut off and the combustion is stopped, the smoking mechanism 11
Is activated for a predetermined period of time to aspirate and analyze residual smoke in the rest of the cigarette roll.

As described above, the burning position detecting mechanism 41 for detecting infrared rays when the burning portion at the tip of the tobacco roll 4 reaches a predetermined burning length is provided. Less than,
Referring to FIG. 10 to FIG.
1 will be described.

When the combustion position detecting mechanism 41 has burned a predetermined length from the leading end of the cigarette winding detected by the above-described device for detecting the leading end position of the cigarette winding, the combustion is performed up to the predetermined position. This is to detect the advance and operate the cutting mechanism 36 described above.

The combustion position detecting mechanism 41 has a detecting head 91, and the detecting head 91 is configured to be moved forward and backward and rotated by a head moving mechanism 90. That is, the detection head 91 is
2, the detection head 91
Are arranged diagonally below the smoking mouth. The rod 92 is connected to the front plate 5 of the smoking machine main body 1 described above.
The bearing 93 is rotatably and slidably supported by a bearing 93, and penetrates the front plate 5 horizontally.

A rotary actuator 95 is provided inside the smoking machine main body 1, and a cylindrical sleeve 96 is connected to the rotary actuator 95. The sleeve 96 has a pair of slits 97 facing each other at 180 ° along the axial direction. The rear end of the rod 92 is inserted into the sleeve 96.
A pin 98 projecting in a letter shape is slidably fitted in the sleeve 96. Therefore, the rod 92 and the detection head 91 are rotated by the rotary actuator 95 described above.

A moving member 99 is provided in the smoking machine main body 1 so as to be movable in the axial direction of the rod 92, and the moving member 99 is reciprocated in the axial direction of the rod by an actuator (not shown). You. The moving member 99 is connected to the pin 9 at the rear end of the rod 92.
8, the moving member 99 moves so that the rod 92 slides back and forth in the axial direction, and the detection head 91 moves in the front and rear direction. .

FIGS. 11 and 12 show the structure of the detection head 91 described above. The detection head 91 includes housings 101 and 102, which are assembled via an O-ring 103. And this housing 10
An infrared sensor 104 is accommodated in each of the light emitting devices 1 and 102. As the infrared sensor 104, for example, a Ge photodiode having a characteristic of having a large sensitivity to infrared rays having a short wavelength emitted from the burning part of the cigarette is used.

The housing 101 has an opening 106 for allowing infrared rays to enter the infrared sensor. A hood 107 protrudes outward from the opening 106.

The hood 107 has a semicircular cross section, and is arranged so that its arc-shaped portion faces forward, that is, the tip side of the cigarette roll, and its edge portion faces rearward, that is, the base end side of the cigarette roll. I have.

The combustion position detecting mechanism 41 operates as follows. First, when the cigarette winding 4 is mounted, the combustion position detection mechanism 41 is retracted, and the rod 92 pushes out the pin 98 of the combustion position detection mechanism 41 with the moving member 99 to count the position of the head. cm forward.
Then, the moving member 99 is retracted to the original position, and the head 91 can freely move back and forth. When the rod 92 is rotated, the hood 1 of the detection head 91 is rotated.
07 is oriented in the horizontal direction. Therefore, when the holder 3 and the cigarette roll 4 are mounted, the detection head 91 is prevented from interfering with the arm 32 of the robot 31, the gripping mechanism 35, and the like.

Next, when the cigarette winding 4 is mounted and the position of the leading end of the cigarette winding is detected by the cigarette winding leading end position detecting device as described above, the detected position of the leading end is used as a reference. Then, the combustion stop position of the cigarette winding, that is, the position of a predetermined expected burning length from the leading end of the cigarette winding is calculated. When the detection head 91 moves forward, the rod 92 rotates to rotate the hood 1 of the detection head 91.
07 is directed obliquely upward, that is, the side surface of the wound cigarette. The hood 107 of the detection head 91 is positioned by the arm 32 of the robot 31 at the position of the above-described combustion length, and thereafter, the cigarette is ignited to start combustion.

When the burning of the tobacco roll 4 proceeds and the black line, which is the boundary between the burned portion and the unburned portion, exceeds the position of the tip of the hood 107, the wavelength of the comparatively long wavelength radiated from the burned portion is reduced. Short infrared rays enter the infrared sensor 104 of the detection head 91, and the infrared sensor 104 detects this and outputs a signal. When the detection signal is output, the rod 92 rotates and the hood 1
07 points in a substantially horizontal direction, and the arm 3 of the robot 31
2 and the interference with the cutting mechanism 36 of the work hand 33 and the like. Then, the robot 31 is detected by the detection signal.
Operates to cut off the combustion portion of the cigarette winding 4 by the cutting mechanism 36, and the combustion is stopped.

In this case, since the hood 107 of the detection head 91 has a semicircular cross section, the detection accuracy of the position of the combustion section is improved. That is, as shown in FIG. 13, infrared rays are radiated in all directions from the burning part of the cigarette. The hood 107 regulates the direction in which the infrared ray enters the infrared sensor 104, and transmits the infrared ray to the infrared sensor 10 only when the black line at the boundary between the burned portion and the unburned portion exceeds the tip of the hood 107.
7 is incident.

Since the hood has a semicircular cross section as described above, there is no internal reflection and the incident direction of the infrared rays can be strictly controlled. That is, for example, when the hood has a circular cross section like the hood 107a shown in FIG. 14, the hood 107a enters the tip of the hood 107a from an oblique direction before the combustion part advances to a predetermined position at the tip of the hood 107a. Infrared light is a hood 107 having a circular cross section.
The light is reflected inside a and enters the infrared sensor 104. However, a hood 1 having a semicircular cross section as described above
If it is 07, there is no reflection inside as described above, and the infrared ray enters the infrared sensor only when the black line at the boundary between the burned part and the unburned part exceeds the position of the tip of the hood 107. Therefore, the accuracy of detecting the position of the combustion part is improved.

After the burning part is cut off as described above, the smoking mechanism 11 continues to operate for a predetermined time.
The smoke remaining in the unburned part of the cigarette is aspirated and analyzed. Therefore, the accuracy of this analysis result is improved.

The present invention is not limited to the above embodiment. For example, in the above-described embodiment, the automatic winding device for attaching and detaching a cigarette and a holder is provided, and a cutting mechanism is detachably provided in the automatic winding device. It is not limited to. For example,
This cutting mechanism may be provided in another cutting device and configured to operate separately from the automatic winding / unloading device described above.

[0055]

As described above, according to the present invention, the cutting mechanism is provided with a pair of cutting blades, each of which has a mountain-like tip, and the tops of these mountain-shaped cutting blades face each other. When the opening and closing members are close to each other, the tips of the cutting blades overlap each other in the thickness direction of the cutting blades. Therefore, the cutting blade first pierces the side of the cigarette roll and cuts the cigarette roll so that the wrapper is cut open on both sides. Therefore, the load applied to the cutting blade may be small, and the winding of the tobacco will not be crushed or deformed during cutting. In addition, the cutting blade has a chevron shape, and the load applied to the tobacco winding at the time of cutting is symmetrical, and the winding of the tobacco does not shift during cutting. Therefore, accurate and reliable cutting can be performed.
