Therefore, if the five holder trays 63 and the winding tray 62 are mounted at the beginning of the day's work as described above, the vicinity of the automatic smoking apparatus for one day, that is, within the working radius of the robot apparatus 30, will be described. There is no need for workers to enter. For this reason, it is possible to operate the automatic smoking apparatus continuously throughout the day without interrupting the operation.

After mounting the holder tray 63 and the winding tray 62 in this manner, the automatic operation of the automatic smoking apparatus is started. First, the elevating rack 81 of the holder tray supply mechanism 66 moves up and down, and the holder tray moving mechanism 83 operates, so that the first holder tray 63 is supplied onto the holder tray mounting table 84. At the same time, the winding tray carrier 70 is lifted by the elevating mechanism 71 to pull out and hold the first winding tray 62 from the winding tray rack 68, and is moved by the elevating mechanism 71 and the horizontal moving mechanism 72. Move to the section.

Next, the robot main body 31 which has moved to the end of the rail 32 receives the winding tray 62 on the winding tray carrier 70 of the winding tray supply mechanism 65, and the robot main body 31 Roller tray holder 61
Hold on.

After the transfer of the winding tray 62 is completed, the above-mentioned winding tray carrier 70 is moved horizontally.
Move horizontally up and back. Next, the robot main body 31 of the robot device 30 moves to the position of the mounting table 35 along the rail 32, and the holder hand 42 is mounted on the hand mounting portion 34 at the distal end of the arm 33.

Next, the robot main body 31 moves to the terminal end of the rail 32, and the holder tray mounting table 84 of the holder tray supply mechanism 66 disposed at the terminal end.
One holder 3 is gripped from the upper holder tray 63. Next, the robot main body 31 moves to the position of the smoking mouth 2 at the end of the smoking machine main body 1, and the holder 3
Is attached to the smoking opening 2. Hereinafter, the above-described operation is repeated, and the holder 3 is sequentially attached to each smoking port 2 of the smoking machine main body 1.

Next, the robot body 31 moves to the position of the mounting table 35 for the various hands, and the arm 3
3. Remove the holder hand 42 at the tip of
5 and a new winding hand 41 is attached to the distal end of the arm 33.

Next, while holding the winding tray 62, the robot main body 31 moves along the rail 32 to the first position of the smoking opening 2 where the winding is to be mounted. Then, the winding C on the winding tray 62 is gripped by the winding hand 41 at the end of the arm 33 of the robot main body 31, and the winding is mounted on the holder 3 mounted on the smoking opening 2. When the mounting of the winding C is completed, the winding hand 41 releases the grip of the winding C, and in accordance with the data such as the brand of the winding C stored in the control device 6, the winding hand 41 performs the mounting. The roll C moves along the axial direction to a predetermined position corresponding to the leading end thereof and stops.

In this state, as described above, a belt-like laser beam is radiated from the projector 55 of the position detecting mechanism mounted on the winding hand 41 into a predetermined range, and the laser beam is received by the light receiver 56. You. In this case, a part of the laser light is blocked by the tip of the mounted winding C, and the light receiver 56 detects the amount of the received light from the winding C.
Detects the length of the part blocked by. As a result, the position of the leading end of the attached winding C is accurately detected, and data on the position of the leading end of the winding C is stored in the control device 6 for each winding C.

The control unit 6 determines the combustion stop position of the volume C from the stored length data of the volume C and the leading end position of the volume C from the stored brand data of the volume C. Is calculated, and this signal is fed back to the robot body 31. The robot body 31 moves the hand 41 based on the feedback signal, and moves the head 22 of the combustion position detecting mechanism 20 as described above.
To the predetermined combustion stop position.

The robot body 31 repeats such an operation while moving along the rail 32, and sequentially mounts the windings C on the holders 3 of the respective smoking openings 2. In this case, the winding C is gripped from the winding tray 62 held by the robot main body 31 and moved together with the winding main body 31 and is mounted on the holder 3 of the smoking opening 2. The robot body 31 only needs to move so as to sequentially correspond to each of the smoking openings 2 from the end, and the time required for mounting the winding C is reduced.

When the mounting of the winding C is completed in this way,
The robot main body 31 moves to the position of the mounting table 35 of the hand, and replaces the winding hand 41 at the tip of the arm 33 with the writer hand 44. The robot main body 31 sequentially ignites the leading ends of the mounted windings C while moving along the rails 32.

In this case, the writer hand 44
, The heater 45 opposes at a slight interval of about 1 mm from the leading end of the winding C, and in this state,
Draws air through this winding C and thereby ignites. In this case, since the positions of the leading ends of the windings C are accurately detected and stored when the windings C are mounted as described above, the heater 45 of the writer hand 44 is brought very close to the leading end of the winding C. In addition, it is possible to prevent the heater 45 from interfering with the leading end of the winding C and to prevent the winding C from being displaced.

At the time of the ignition operation, the control device 6 controls the value of current supplied to the heater 45, and maintains the temperature of the heater 45 at a predetermined temperature. The current value to the heater 45 is constantly monitored by the control device 6, and when the current value becomes equal to or less than a predetermined value, it is determined that the heater 45 of the writer hand 44 is disconnected.

In this case, the robot body 31 is moved by the control device 6 to the position of the mounting table 35 of the hand, and the disconnected writer hand 4 is moved.
4 is replaced with a spare lighter hand 44, and the ignition operation as described above is continued again. Therefore, the ignition operation, the smoking test, and the like are not interrupted by the disconnection of the lighter hand, and a reliable test can be performed. Further, even if the heater 45 of the lighter hand 44 is disconnected as described above, the ignition operation and the smoking test are not hindered as described above.
As described above, the temperature of the heater 45 of the lighter hand 44 is set to a high temperature of 600 ° C. or more, preferably 700 ° C. or more, so that the ignition of the winding C can be more reliably performed.

Further, in order to ensure the ignition of the winding C, the ignition of the winding C is confirmed by the above-mentioned ignition failure detecting mechanism. That is, the infrared detector 91 of the ignition failure detection mechanism is attached to the robot main body 31 as described above, and the infrared detector 91 is the one turn before the turn C ignited by the lighter hand 44 at the tip of the arm 33. It is configured to detect infrared rays from the tip of C. The signal from the infrared detector 91 is sent to the control device 6 to measure the temperature of the leading end of the winding C based on the amount of infrared light and the spectral distribution from the leading end of the winding C.
If the temperature is equal to or lower than a predetermined set value, for example, 50 ° C. or more lower than the temperature in the case where ignition is performed properly, it is determined that the ignition of the winding C has failed.

The controller 6 stores the position of the winding C in which the ignition has failed, and the robot body 31 has failed in the ignition after the ignition work on all the windings C is completed. Returning to the position of the winding C, the winding is again ignited.

The ignition of the winding C is performed by sucking air through the winding C while the heater 45 of the lighter hand 44 is close to the tip of the winding C as described above. Does not ignite this volume C,
In addition, there is a case where the fire disappears after ignition. Also in these cases, the infrared detector 91 detects the infrared ray from the leading end of the immediately preceding winding C after a predetermined time has elapsed since the ignition.
Therefore, the failure of the ignition of the winding C can be reliably detected. Therefore, it is possible to reliably prevent the smoking test from being redone again due to the failure of the ignition.

After the ignition of the winding C of each of the smoking openings 2 as described above, the smoking machine main body 1 performs the predetermined smoking test operation as described above, and measures the number of puffs and the burning rate of each winding C. , And component analysis.

The robot main body 31 moves to the position of the mounting table 35, replaces the writer hand 44 at the tip of the arm 33 with the cutting hand 43, and waits until the combustion of these windings C is completed. I do. When each of the above-mentioned turns burns to a predetermined combustion end position, infrared rays are detected by the head 22 of the combustion position detecting mechanism 20 of the smoking machine main body 1, and it is detected that the turn C has burned to a predetermined position. . This signal is sent to the control device 6, which sends a control signal to the robot device 30. Then, the robot body 31 moves to the position of the winding C where the combustion is completed, and the cutting hand 4 is moved.
At 3 the fire is extinguished by cutting the end of the winding C.

The above operation is repeated to cut off the end of the wound C after burning, extinguish the fire, and remove the butts and the like. In this case, the setting of the head 22 to the combustion stop position, the cutting of the leading end of the winding C by the cutting hand 43, and the like are performed based on the detection data of the position of the leading end of the winding by the position detecting mechanism of the winding hand 41. It is possible to end the combustion and cut and extinguish the fire at the correct position.

When the smoking test is completed for all the windings C as described above, the robot device 30 again mounts the windings C on the holders 3 of the respective smoking openings 2 as described above.
A series of operations such as ignition, smoking test, cutting and extinguishing are performed.
