Next, the structure of each part of such an apparatus will be described. 5 to 7 show the structures of the hopper 11 and the receiving drum 13 described above. FIG. 5 shows the structure of the receiving drum 13 and the supply passage 14 corresponding thereto.

A block 40 is provided in the bottom portion of the hopper 11, and the supply passage 14 is formed in the block 40. Holding projections 41 are provided at the lower ends of the supply passages 14, respectively, and suction holes 43 are formed in the holding projections 41. The suction holes 43 are formed by a negative pressure mechanism (not shown). )It is connected to the. Therefore, the cigarettes C which are supplied in a line in the supply passages 14 are sucked and held by the holding projections 41 by the negative pressure.

Further, the receiving drum 13 is provided with, for example, two receiving holders 42 in a protruding manner. These receiving holders 42 are also provided with suction holes (not shown) connected to the negative pressure mechanism, and are configured to suck and hold the cigarette C on the receiving holders 42. Therefore, when the receiving drum 13 rotates and the receiving holder 42 passes the lower end of the supply passage 14, the receiving holder 42 receives one cigarette held by the holding convex portion 41. Hold.

On the peripheral surface of the alignment drum 12, one row, that is, seven or six holding grooves 44 are formed side by side, and suction holes are opened in the holding grooves 44, respectively. The cigarette C is sucked and held in the holding grooves 44. Each time the aligning drum 12 rotates and passes through the receiving drums 13, the cigarettes C are sequentially transferred from the receiving drums 13 into the holding grooves 44 one by one. One row, that is, seven or six cigarettes C, are held in the holding groove 44 in an aligned state.

Next, a mechanism for smoothly introducing the cigarette C from the hopper 11 into the supply passage 14 will be described. That is, a large number of cigarettes are accommodated in the hopper 11, but when the large number of cigarettes are introduced into the supply passage 14 in a line, the supply passage 14
In the vicinity of the entrance of the upper end of the cigarette, the cigarettes are pressed against each other to form a bridge, and a phenomenon occurs that hinders the smooth flow of the cigarette. In order to prevent such a bridge phenomenon,
A pair of agitator rollers 45 are provided on both sides of the upper end entrance portion of the supply passage 14. Further, at a position above the upper end entrance of the supply passage 14,
A plurality of blade-shaped agitator vanes 47 are provided, and these agitator vanes 47 have a substantially streamlined shape so as not to obstruct the flow of cigarettes. Then, as shown in FIG. 6, these agitator rollers 45
A rotary shaft 46 is connected to, and a rotary shaft 48 is also connected to the agitator vane 47. The rotating shafts 46 and 48 penetrate the rear wall of the hopper 11 and project to the rear of the hopper 11. The pinion 4 is attached to the rear end of each of the rotary shafts 46 and 48.
9,51 are attached. Racks 50 and 52 are meshed with these pinions 49 and 51, respectively. Then, these racks 50 and 52 are reciprocally moved by the drive mechanism as shown by the arrow in FIG. 6, whereby the agitator roller 45 and the agitator vane 47 are reciprocally rotated as shown by the arrow.

As described above, the reciprocating rotation of the agitator roller 45 causes the cigarette at the upper end entrance portion of each supply passage 14 to reciprocate in the horizontal direction, and the cigarette at the entrance portion is blocked in a bridge shape. To prevent. Further, by the reciprocating rotation of the agitator vane 47,
The cigarettes further above the entrance portion are reciprocated largely in the horizontal direction to smooth the flow of the cigarettes and prevent the cigarettes from being jammed in a bridge shape. Since these agitator vanes 47 reciprocally rotate in synchronization with each other, the cigarette is generally reciprocally moved in the horizontal direction, and such movement does not crush the cigarette or disturb the flow. Absent.

Next, the structure of the supply passage 14 will be described. These supply passages 14 are formed by a block 40 provided at the bottom of the hopper 11. A rear wall 59 closes the rear portions of these blocks 40. As shown in FIGS. 5 and 7, the wall portions on both sides of these supply passages 14 are composed of a pair of wall members 55. And these wall members 5
The upper end of 5 is formed into a tapered portion 56 so that the cigarette C can be smoothly introduced into these supply passages 14.

Further, on the inner side surfaces of these wall members 55,
The notch exclusion groove 57 is formed in each case. These notch removal grooves 57 are, for example, formed so as to be inclined from the front side toward the rear side. Further, other notch removal grooves 57a are formed in the inner peripheral portions of these wall members 55 along the vertical direction.

Then, the lower end portion of the above-mentioned nick removing groove 57,
A suction hole 58a is formed in the back wall 59 so as to correspond to the lower portion of the notch removal groove 57a. These suction holes 58a are formed with a diameter that allows the cut tobacco pieces to pass therethrough, pass through the back wall 59, and are located at the lower back end of the cut removal groove 57 and the cut removal groove 57a, respectively. It communicates with the bottom.

A notch removal passage 58 is provided behind the back wall 59. The notch removal passage 58 communicates with the suction holes 58a and is connected to a suction mechanism (not shown).

From the cigarette C housed in the hopper 11 described above, some tobacco leaf cuts are removed. The dropped notch may enter the supply passage 14 and be caught between the cigarette C moving in the supply passage 14 and the wall to prevent the smooth movement of the cigarette C.
Further, the nicks may reach the receiving drum 13 and the aligning drum 12 below, and may be mixed between the bale-wound cigarettes. However, by forming the above-described notch removal groove 57, the dropped notch falls into these notch removal grooves 57, and the inclined notch removal groove 5 is formed.
The inside of 7 is dropped by gravity and suction negative pressure, and is dropped into the nick removing passage 58 to prevent the above problems.
Since the nicks 57 are inclined, the cigarette C that moves downward in a horizontal posture does not get caught in the nicks 57 even if the width is large.

Further, these cigarettes C fall in the supply passage 14 with their tip ends facing the inner wall 59 side, but the nicks that have fallen off the tip portions of these cigarettes C It falls into the above-described vertical nick removal groove 57a and is removed in the nick removal passage 58 in the same manner as described above.

Next, the structure of the alignment drum 12 will be described with reference to FIGS. This alignment drum 12
As described above, a plurality of groups of holding grooves 44 each holding one row of cigarettes are formed. Then, suction holes 60 are opened in these holding grooves 44. The alignment drum 12 is formed in a hollow cylindrical shape, and the other end of the suction hole 60 is open to the inner peripheral surface thereof.

Further, as shown in FIG. 9, a core member 61 is attached to a plate 62 on the fixed side of the apparatus, and a cylindrical suction sleeve 63 is fitted around the outer periphery of the core member 61. , These members do not rotate. In addition, the shaft 68 passes through the center of the core member 61.
Is provided, and the shaft 68 is rotatably supported by bearings 66 and 67. And the above-mentioned alignment drum 1
The 2 is mounted on this shaft 68 and rotates with it. The inner peripheral surface of the alignment drum 12 is airtightly rotatably fitted to the outer periphery of the suction sleeve 63. In addition, 64 is a V ring for maintaining airtightness.

A suction groove 65 is formed along the circumferential direction on the outer peripheral surface of the suction sleeve 63. This suction groove 65 is provided in the suction passage 7
It is connected to a suction mechanism (not shown) via 1, 72, 73 and 74. Therefore, when the aligning drum 12 rotates and the suction holes 60 correspond to the suction grooves 65, a negative pressure acts on the suction holes 60 and the cigarettes transferred from the receiving drum 13 to the holding grooves 44. C is adsorbed and held.

Further, FIG. 10 is a view showing the alignment drum 12 and the suction sleeve 63 developed in the circumferential direction. As shown in this figure, the suction groove 65 described above is also used.
An open groove 70 is formed in the vicinity of the terminal end in the rotation direction of
The open groove 70 communicates with the atmosphere via a passage 69. Therefore, when the holding groove 44 that sucks and holds the cigarette corresponds to the position of the opening groove 70, the negative pressure in the suction hole 60 is released, the held cigarette is released, and the cigarette is transferred to the transfer drum 15. To be done.

The alignment drum 12 and the receiving drum 13 are rotated in synchronization with each other via gears 75 and 76 in a predetermined relationship.

As shown in FIG. 10, two suction holes 60 are provided in each holding groove 44. The distance between these two suction holes 60 is the narrowest in the holding groove 44 on the tip side in the rotation direction of the suction grooves 44 of each group, and these two suction holes 60 move toward the opposite side to the rotation direction. The holes 60 are configured such that the intervals between the holes 60 gradually increase. The end of the suction groove 65 on the side opposite to the rotating direction has the narrowest tip portion, and the position of each of the receiving drums 13, that is, the receiving drums 1 is described.
The width of the suction groove 65 is gradually increased stepwise corresponding to the position where the cigarettes sequentially wound from 3 are transferred to the holding groove 44.

Therefore, when the cigarettes from the first receiving drum 13 are transferred to the first holding grooves of the holding grooves 44 of a certain group, the two first holding grooves 44 having the smallest spacing are provided. Of the suction groove 65 corresponds to the narrowest part of the suction groove 65, and a negative pressure acts on the suction hole 60 to suck and hold the transferred cigarette in the holding groove 44. The suction holes of the other holding grooves do not correspond to this suction groove, and negative pressure does not act on them. Then, when the cigarette is transferred from the second receiving drum 13 to the second holding groove 44 next, the two suction holes 60 having the second widest spacing between the second holding grooves 44 form the suction grooves. Negative pressure is applied to the suction hole of the second holding groove corresponding to the portion having the second largest width after 65, and sucks and holds the transferred cigarette. In the following, the suction holes of the holding grooves to which the cigarettes are sequentially transferred communicate with the suction grooves in this manner, and the suction holes of the holding grooves to which the cigarettes have not yet been transferred do not communicate with the suction grooves.

By such an operation, the suction holes 60 of the holding groove 44 to which the cigarette has not yet been transferred do not communicate with the suction groove 65, so that a large amount of the suction hole of the holding groove does not hold the cigarette. Air is sucked, and the suction mechanism is overloaded, and the suction passage 6
It is possible to prevent such a problem that the negative pressure in 5 becomes weak and the suction holding force of the cigarette is lowered.

As shown in FIG. 2, transfer drums 15 are arranged between each of the alignment drums 12 having the above-mentioned structure and the above-mentioned bag stacking drum 16. These transfer drums 15 have substantially the same structure as the alignment drum 12 described above, and holding grooves of an odd number of groups, for example, three groups are formed on the peripheral surface thereof, and the number of the holding grooves of each group is a cigarette. The number for one row, that is, seven to six. Then, suction holes are opened in these holding grooves in the same manner as described above.

The cigarettes of which the number of rows is aligned on each of the above-mentioned aligning drums 12 are transferred to the above-mentioned transfer drum 15 one by one, and are sucked by the holding grooves of each group of this transfer drum 15. Retained. Then, the held cigarettes for one row are collected by the bales stacking drum 1 for each row.
Transferred to 6.

Since the transfer drums 15 are provided with an odd number of holding grooves as described above, while a certain number of holding grooves are being transferred to the receiving drum 13 while the cigarette is being transferred. The holding groove of the other group is the above-mentioned baling stack drum 1
6 is not supported, and the transfer from the transfer drum 15 to the bale stacking drum is not performed. Further, while the holding groove of a certain group is being transferred to the bale stacking drum in correspondence with the bale stacking drum 16, the holding groove of another group is not transferred from the receiving drum. Therefore, the transfer of the cigarettes from the receiving drum 13 to the transfer drum 15 and the transfer of the cigarettes from the transfer drum 15 to the bale stacking drum 16 are performed with a staggered timing.
Then, the transfer drum 15 is driven by a cam mechanism or the like so that the rotation speed intermittently changes, and the alignment drum 1
When the cigarettes are transferred from 2, the alignment drum 1
It rotates at a peripheral speed equal to the peripheral speed of 2 and at the same peripheral speed as the peripheral speed of the bale stacking drum 16 when the cigarette is transferred to the bale stacking drum 16. Therefore, it is not necessary to match the peripheral velocities of the alignment drum 12 and the bale stacking drum 16, and the peripheral velocity of the receiving drum 13 can be made lower than the peripheral velocity of the bale stacking drum 16. Speeding up becomes easy.

Further, by providing the transfer drum 15 as described above, the diameter of the bales stacking drum 16 can be reduced. That is, it is necessary to arrange one row, that is, seven or six receiving drums 13 around the above-mentioned alignment drum 12. Further, it is necessary to supply the cigarettes to the receiving drums 13 from the supply passage 14 by gravity, and it is preferable that the shape of the supply passages 14 is vertical and close to a straight line. Therefore, these receiving drums 12 need to be arranged in the upper part of the alignment drum 13. Under such conditions, it is necessary to increase the diameter and the arrangement interval of the alignment drums 13 to some extent. Therefore, the diameter of the above-mentioned bale stacking drum 16 must be correspondingly larger than necessary for operation. However, when the transfer drum 15 is arranged as described above, the distance between the bale stacking drum 16 and each alignment drum 12 is increased by a distance corresponding to the diameter of the transfer drum 15. Therefore, even if the example of the bale stacking drum 16 is made small, the arrangement drum 12 and its arrangement interval can be made sufficiently large.

Next, the construction of the above-mentioned bag stacking drum 16 will be described with reference to FIGS. 11 to 13. As described above, the baler stacking drum 16 includes a plurality of baler stacking heads 17.
Is provided. Then, the cigarettes are transferred from the transfer drum 15 to the bales stacking heads 17 one row at a time, and the rows of the cigarettes are stacked on the bales stacking head 17 in a bales stacking manner to store 20 cigarettes for one box. Cigarettes are stacked in a bag.

The cigarettes stacked in a bag on the bag stacking head 17 are transferred to the intermediate drum 19 by the pusher 21 protruding from the extruding drum 18 as shown in FIG.
Be transferred to. On the other hand, as shown in FIG. 4, the head 22 of the intermediate drum 19 described above transfers the cigarettes stacked in a bag with the head 30 of the first drum 20a of the packing device 2, so that the drum It swings in response to rotation. Therefore, the bales stacking head 17 of the bales stacking drum 16 also performs the same swinging operation in synchronization with the swinging operation.

FIG. 11 shows a mechanism for swinging the bales-stacking head 17. That is, these bales stacking heads 17 are rotatably attached to the bales stacking drum 16 in a direction orthogonal to the axial direction. Further, each of the bales stacking heads 17 is formed with a sector gear portion 80. Further, sector gears 81 are also provided on the side of the above-mentioned bale stacking drum 16, and these sector gears 81
Engages with the sector gear portion 80 of the bales stacking head 17. Then, a cam follower 82 is formed on each of these sector gears 81, and these cam followers 82 are fitted to a circumferential cam 83 provided on the fixed side.

Therefore, when the bales stacking drum 16 rotates, the cam followers 82 are driven, and the bales stacking heads 17 via the sector gears 81 and the sector gears 80 are driven.
Rotates. The above-described shape of the circumferential cam 83 is set so that the swinging operation of the bales stacking head 17 is synchronized with the swinging operation of the head 22 of the intermediate drum 19. Therefore, the posture of the above-mentioned bale stacking head 17 is
When the cigarettes transferred from the transfer drum 15 to the bale stacking drum 16 are braked in the circumferential direction, other than that, it corresponds to the posture of the head 22 of the intermediate drum 19, so that the baleed cigarettes are surely collected. With the transfer, the pusher 21 of the push-out drum 18 starts to move forward and the period until the transfer of the cigarettes of the baling stack drum 17 to the head 22 of the intermediate drum 19 is completed can be lengthened. The speed of the reciprocating movement of the pusher 21 can be slowed down, and the speedup of this device is easy.

Next, a mechanism for stacking a row of cigarettes from the transfer drum 15 onto the bag stacking head 17 will be described. Since the cigarettes stacked in a plurality of stages are stacked on the bag stacking head 17, as described above, the sucking and holding by the negative pressure cannot hold these cigarettes against the centrifugal force, and thus FIG. It is held by a mechanism as shown in FIG. Note that, in FIG. 12, for convenience of description, three transfer drums 15 are arranged in the order of the rotation direction of the bale stacking drum 16 a,
The symbols are distinguished from 15b and 15c.

The row of cigarettes for one row held on the first transfer drum 15a is released from the suction holding and guided by the guide members 91 and 92, and the baling head 17
Transferred to the top. The guide member 92 has an arc-shaped surface facing the bag stacking drum 16, and the radius of the arc is the upper surface of the first-row cigarette row transferred to the bag stacking head 17. It is almost the same as the radius of the trajectory drawn by. Therefore, the cigarette C of the first stage is held by the guide member 92 and is prevented from being scattered by the centrifugal force.

Further, when the bales stacking head 17 moves to the position of the second transfer drum 15b, the second row of cigarettes C is transferred from the second transfer drum 15b,
The bales are stacked on top of the first row of cigarettes. In this case, the row of cigarettes to be transferred is guided between the rear end of the guide member 92 and the front end of the next guide member 93. Further, the distance between the second transfer drum 15b and the bale stacking drum 16 is higher than the distance between the first transfer drum 15a and the bale stacking drum 16 by one line of cigarettes. It's bigger than the distance. Therefore, the row of cigarettes in the second stage is smoothly stacked on the row of cigarettes in the first stage. In addition, the surface of the guide member 93 facing the bale stacking drum 16 is also formed in an arc shape, and the radius thereof matches the radius of the locus drawn by the upper surface of the second-row cigarette row. Therefore, the first-stage and second-stage cigarette rows are guided and held by the inner peripheral surface of the guide member 93.

Further, when the bales stacking head 17 moves to the position of the third transfer drum 15c, the third row of cigarettes is transferred from the third transfer drum 15c onto the bales stacking head 17, More bales are stacked on the second row of cigarettes.
