4Be illustrated in cylinder and be that two cigarette with filter tip DFS are cut off into 2 cigarette with filter tip FS on 34, then these cigarette with filter tip FS appearance of becoming to be separated from each other.
As shown in Figure 2, roll extrusion parts 6 have accept cut paper P accept cylinder 38.This accepts cylinder 38, and to be configured in cylinder be that 4 outlet cylinder 40 and cylinder are between 34 the inlet cylinder 42.More particularly, accept the upside of cylinder 38, these cylinders 40,42 continuous ground connection are being disposed at cylinder 40,42.
Accept the length that the outer peripheral face width of cylinder 38 is a bit larger tham intermediate I.From accepting the axis direction of cylinder 38, the outer peripheral face middle body of accepting cylinder 38 forms along the suction surface in full week.Therefore, be guided next cut paper P with the state of its paste applicator surface, be adsorbed on the suction surface of accepting cylinder 38 towards the outside along supply line.Then, along with up time meter direction (Fig. 2) rotation of accepting cylinder 38, cut paper P supplies with towards the direction of rotation of accepting cylinder 38.From accepting the direction of rotation of cylinder 38, can the attract when suction surface of accepting cylinder 38 can be accepted only in the θ of anglec of rotation zone supplied with.From Fig. 2 as seen, anglec of rotation zone θ is from the top of accepting cylinder 38, finish near the position of outlet cylinder 40 peripheries in the periphery of accepting cylinder 38.
If intermediate I is that travelling speed on 4 is V at cylinder
1, then accept the outer peripheral face translational speed of cylinder 38, promptly accept the peripheral speed V of cylinder 38
2Be set at the travelling speed V of intermediate I
12 times.
Disposing rotatable band sword cylinder 44 on the outside of accepting cylinder 38 corresponding with the attraction zone θ of cut paper P.The outer peripheral face of band sword cylinder 44 has several swords 46.These swords 46 are equally spaced to be configured in the Zhou Fangxiang of band sword cylinder 44.The direction of rotation of band sword cylinder 44 is opposite with the direction of rotation of accepting cylinder 38.Therefore, along with the rotation of accepting cylinder 38, when the cut paper P on accepting cylinder 38 passed through band sword cylinder 44, cut paper P was cut to specific length by the blade 46 with sword cylinder 44.As a result, on the suction surface of accepting cylinder 38, form individual filter tip scraps of paper Pc.Then, these filter tip scraps of paper Pc is moved to the terminal that attracts the zone.The suction surface of accepting cylinder 38 is determined the feed path of filter tip scraps of paper Pc.
Disposing rolling plates 48 at the downside of accepting cylinder 38, this rolling plates 48 is by keeping seat 50 supporting.The upper surface of rolling plates 48 forms the circular-arc rolling surface 49 that extends along the outer peripheral face of accepting cylinder 38.Be two cigarette with filter tip DFS, be 3 times of full Zhou Changdu of intermediate I along the length of accepting the rolling surface 49 of cylinder 38 all directions.Therefore, intermediate I can be along Zhou Fangxiang rotation 3 circles of accepting cylinder 38 on rolling surface 49.In addition, from accepting the axis direction of cylinder 38, the width of rolling plates 48 approximates the length of intermediate I.Keep keeping electric heater 51 in the seat 50, this heater 51 be positioned at rolling plates 48 near.Electric heater 51 is heated to proper temperature with rolling plates 48.
Protruding ground is crooked towards the below for rolling plates 48 and accept to have determined between the cylinder 38 roll extrusion path 52, this roll extrusion path 52.The height of this roll extrusion path 52, be rolling surface 49 and accept the diameter that interval between cylinder 38 outer peripheral faces is slightly smaller than intermediate I, and be certain along the Zhou Fangxiang that accepts cylinder 38.
From Fig. 3 as seen, on rolling surface 49, form a pair of recess 54.These recesses 54 are positioned at the downstream part of roll extrusion path 52 from the direction of rotation of accepting cylinder 38, and left and right symmetrically in sunder.Each recess 54 for example has the degree of depth of 0.5～1.0mm.Stay the position of the rolling surface 49 between the left and right sides recess 54, its width W is a bit larger tham the length of the filter tip F of intermediate I.Specifically, width W is identical with the width of cut paper P.
From the inlet of roll extrusion path 52 to the arc length of a pair of recess 54, promptly from the arc length L of rolling surface 49 upstream extremities up to the rolling surface 49 of recess 54
1Equal the full Zhou Changdu of intermediate I, the long L of the circular arc of left and right sides recess 54
2Be 2 times of full week of intermediate I.
Giving prominence to several pawls 56 from the upstream extremity of rolling plates 48, these pawls 56 extend along the imaginary elongated surfaces of rolling surface 49.Each pawl 56 does not hinder outlet cylinder 40 to invade rotatably in the outlet cylinder 40.That is, the outer peripheral face of outlet cylinder 40 is formed with several all grooves corresponding with pin 56 (figure does not show).Pawl 56 is copied and is got the intermediate I that is transported on the outlet cylinder 40, conscientiously with its guiding roll extrusion path 52.The downstream of rolling plates 48 is positioned near the outer peripheral face of inlet cylinder 42, and like this, rolling surface 49 is connected between the outer peripheral face of the outer peripheral face of outlet cylinder 40 and the cylinder 42 that enters the mouth sleekly.
Except above-mentioned left and right sides recess 54, the upper surface of rolling surface 49 and each pawl 56 forms the clamping face 57 with great friction coefficient.Specifically, clamping face 57 is to form by the top enforcement embossing processing to rolling surface 49 and pawl 56.In addition, at the upstream extremity of rolling surface 49, form outstanding slightly prominent bar 58 in the central, this prominent bar 58 is circular-arc section, extends to the width of rolling plates 48 more longways than above-mentioned width W.
The following describes the action of above-mentioned roll station 6.
As shown in Figure 4, being set in cylinder is that the travelling speed of the intermediate I that transports on 4 the outlet cylinder 40 is V
1, intermediate I is by entering the mouth with identical travelling speed V
1Enter in the roll extrusion path 52.At the inlet of roll extrusion path 52, the middle body of intermediate I, i.e. part from filter tip F to monovolume cigarette S end are taken advantage of on the prominent bar 58 of rolling surface 49, and intermediate I begins to rotate.Simultaneously, accept filter tip scraps of paper Pc on the cylinder 38 to supply with speed V
2Enter the inlet of roll extrusion path 52, the front end of filter tip scraps of paper Pc is attached to the outer peripheral face of intermediate I.
At this moment, because intermediate I has begun rotating, the translational speed of intermediate I periphery is than travelling speed V
1Hurry up, roughly with the feed speed V of filter tip scraps of paper Pc
2Identical.And prominent bar 58 makes rolling surface 49 and the interval minimizing of accepting between the cylinder 38.Therefore, the front end of filter tip scraps of paper Pc is bonded in the outer peripheral face of intermediate I effectively, the result, and the initial stage of filter tip scraps of paper Pc is bonding to be stabilized enforcement.At this moment, the inlet of the follow-up intermediate I no show roll extrusion still path 52 on the outlet cylinder 40 is not so same filter tip scraps of paper Pc can side by side bond on go ahead of the rest intermediate I and the follow-up intermediate I.
After middle goods I crossed prominent bar 58, the front end of filter tip scraps of paper Pc became the state of holding under the arm accepting between cylinder 38 and the intermediate I, and simultaneously, at this constantly, the attraction of accepting 38 pairs of filter tip scraps of paper of cylinder Pc is disengaged.Therefore, intermediate I roll extrusion path 52 in, roll on one side, one side with the circular velocity V that accepts cylinder 38
2Consistent speed moves.The rolling of this intermediate I makes filter tip scraps of paper Pc peel off and bond to from the outer peripheral face of accepting cylinder 38 on the outer peripheral face of intermediate I, and last, the state that filter tip scraps of paper Pc overlaps mutually with two ends is wound on the intermediate I.
As mentioned above, accept the circular velocity V of cylinder 38
2, be set at the travelling speed V of intermediate I
12 times, so when filter tip scraps of paper Pc is wound up on the intermediate I outer peripheral face, that is, intermediate I only rolls in roll extrusion path 52 when circle at first, the end edge of filter tip scraps of paper Pc does not contact follow-up intermediate I, surpasses this follow-up intermediate I.As a result, follow-up intermediate I and next filter tip scraps of paper Pc synchronously enter in the roll extrusion path 52.
As mentioned above, the initial 1 circle rotation of the intermediate I in roll extrusion path 52 is the L on rolling surface 49
1Carry out in the zone, and this zone is as the clamping face 57 that covers intermediate I total length.Therefore, intermediate I is not to slide on the clamping face 57 at rolling surface 49, but rolls, and filter tip scraps of paper Pc can stably carry out conscientiously for the coiling of intermediate I.
Then, the intermediate I of filter tip scraps of paper Pc that reeled fully, promptly two cigarette with filter tip DFS do two circle rotations along with the rotation of accepting cylinder 38 roll extrusion path 52 in, deviate from from roll extrusion path 52, and moving and taking above-mentioned cylinder is on 34 the inlet cylinder 42.
Because rolling plates 48 is in electric heater 51 heated state that are held in the seat 50, so, the very fast drying of paste applicator surface of the filter tip scraps of paper Pc behind the coiling, firm for the bonding change of intermediate I.
When two cigarette with filter tip DFS rolled in roll extrusion path 52, rolling surface 49 only was formed between a pair of recess 54.Therefore, from Fig. 5 as seen, the middle body of only two cigarette with filter tip DFS, be that part that filter tip scraps of paper Pc is reeling is seized on both sides by the arms in rolling plates 48 and accepted between the cylinder 38, about cigarette portions can by rolling plates 48 with not accept cylinder 38 and seize on both sides by the arms.As a result, about cigarette portions can not rubbed scattered because of the rolling of two cigarette with filter tip DFS, can fully keep the hardness of these cigarette portions.
