Refer again to Fig. 2, near another turning cylinder 10 of configuration inspection cylinder 6, this turning cylinder 108 is parallel with the turning cylinder 14 of checking cylinder 6.Turning cylinder 108 also is enclosed in the fixed hub 112, and its two ends are rotated by pair of bearings 110 and are bearing in freely on the fixed hub 112, and fixed hub 112 is engaged with on the framework 22.
One end of turning cylinder 108 protrudes driven wheel 114 from fixed hub 112 in the rear side of framework 22 and is installed on the end of turning cylinder 108.Driven wheel 114 and above-mentioned driven wheel 24 engagements of checking cylinder 6 sides.Thereby when the turning cylinder 14 of checking cylinder 6 rotated, turning cylinder 108 rotated with turning cylinder 14 direction of rotation ground.
The other end of turning cylinder 108 protrudes from fixed hub 112, and be installed in series on the other end of turning cylinder 108 described cut-out roller 10 and lid roll 12.In more detail, the other end of turning cylinder 108 is connecting common rotor 116, and rotor cover 118,120 is installed on the outer peripheral face of this rotor 116.This rotor cover 118,120 and rotor 116 co-operatings, form respectively cut off roll 10 and lid roll 12.Thereby this rotor cover 118,120 and armature spindle 108 rotate integratedly.
Rotor cover 118,120 has a plurality of cut-out grooves 122 and lid groove 124 respectively on its outer peripheral face, these cut off grooves 122 and lid groove 124 at the Zhou Fangxiang of the sleeve of correspondence with uniformly-spaced configuration, have the shape identical with the groove 46,74 of above-mentioned receiving slit 76.
When the turning set 30 of above-mentioned inspection rotating cylinder 6 and rotor cover 118,120 rotated together, the receiving slit 76 (groove 74,46) that cuts off groove 122 and lid groove 124 relative inspection rotating cylinders 6 lumped together successively in above-mentioned inspection position.Just the spacing of receiving slit 76 is set for identical with spacing and the peripheral speed of cutting off groove 122 and lid groove 124 with peripheral speed.
Below, have the effect that above-mentioned cut-out roller 10 and lid roll 12 inspection rotating cylinder 6 with reference to Fig. 1 and Fig. 4～Fig. 7 explanation.
At first, the rotating cylinder 4 that transports that inspection rotating cylinder 6 is swum is from it delivered to cigarette with filter tip in the receiving slit 76, in more detail, as shown in Figure 1, transports rotating cylinder 4 and has the suction section S that is used to accept and transport cigarette with filter tip
1, this suction section S
1See to transport rotating cylinder 4 and to check in the rotation direction of transporting rotating cylinder 4 and to pass on position in front of the position as terminal between the rotating cylinder 6.In contrast, check that rotating cylinder 6 sees to have the suction section S that begins to extend in front of the position from passing in its rotation direction
2, this suction section S
2Square one-tenth by above-mentioned control mouth 54.
Thereby the cigarette with filter tip on transporting rotating cylinder 4 checks that the receiving slit 76 (groove 46) of rotating cylinder 6 enters suction section S when passing on the position
2, accept from control mouthful 54 negative pressure of supplying with.So receiving slit 76 attracts to transport the cigarette with filter tip on the rotating cylinder 4, receiving filtration mouth cigarette FC as illustrated in fig. 4, received cigarette with filter tip FC is at sealing gasket 60 and attract between the pad 80.
Form the punch block on the scraps of paper of cigarette with filter tip FC, for example form the occasion of a punch column V, this punch column V is placed in the groove 74 (receiving slit 76) of filter tip anchor clamps 72.And the edge E of the scraps of paper of tobacco rod side is placed between tobacco rod anchor clamps 43 and the filter tip anchor clamps 72, is in the full week of spreading all over cigarette with filter tip FC always to expose externally airborne state.At this moment, the cigarette with filter tip FC in the receiving slit 76 is in the state that its tobacco rod is attracted by a pair of groove 46.
Afterwards, along with the rotation of checking rotating cylinder 6, the cigarette with filter tip FC in the receiving slit 76 moves at the Zhou Fangxiang that checks rotating cylinder 6.In this moving process, the cam path 38 of cam sleeve 26 and cam follower 40 mutual co-operatings are moved tobacco rod anchor clamps 43 by slide block 34 and movable carriage 42 to attracting to fill up 80.Like this, cigarette with filter tip FC does not move with tobacco rod anchor clamps 43 slidably together relative to receiving slit 76, the filter end of cigarette with filter tip FC, i.e. and aspiration port contact is attracting on the pad 80.
At this, before cigarette with filter tip FC will contact attraction pad 80, receiving slit 76 was by suction section S
2(with reference to Fig. 1) temporarily stops to supply with negative pressure to receiving slit 76 (groove 46), and in addition, at this moment, groove 46 also can be opened in atmosphere.
After cigarette with filter tip FC contact is attracting pad 80, tobacco rod anchor clamps 43, be that movable carriage 42 also continues to move, at this moment, the 43 relative cigarette with filter tip FC slips of tobacco rod anchor clamps.Thereby sealing gasket 60 moves towards cigarette with filter tip FC, contacts as illustrated in fig. 5 at the tobacco rod end.As a result, cigarette with filter tip FC is clipped between sealing gasket 60 and the attraction pad 80.
Afterwards, receiving slit 76 enters suction section S
3(another control mouth 54) supplies with negative pressure again from control mouth 54 in the groove 46 (receiving slit 76) of tobacco rod anchor clamps 43, cigarette with filter tip FC is attracted and remains in the receiving slit 76.
Even temporarily stop to open in atmosphere to the groove 46 supply negative pressure of tobacco rod anchor clamps 43 or groove 46, cigarette with filter tip FC can not come off from receiving slit 76 yet.That is, disposing guide plate 126 in the outside of checking rotating cylinder 6 as illustrated in fig. 1, it is from suction section S
2Extend and spread all over suction section S
3, prevent that cigarette with filter tip FC is from checking that rotating cylinder 6 comes off.
In addition, even cigarette with filter tip FC is to attracting pad 80 to move, the limit of the scraps of paper also can not enter in the groove 74 of filter tip anchor clamps 72.
Afterwards, cigarette with filter tip FC to be being sandwiched in sealing gasket 60 and attracting state between the pad 80, rolls 12 and moves to cutting off roller 10 and lid.When cigarette with filter tip FC rolls 12 by cutting off roller 10 and lid, during promptly by above-mentioned inspection position, as shown in Figure 6, cut off the cut-out groove 122 of roller 10 (rotor cover 118) and groove 74 co-operatings of filter tip anchor clamps 72, fully seal the punch column V of cigarette with filter tip FC, on the other hand, lid rolls groove 46 co-operatings of the lid groove 124 and the tobacco rod anchor clamps 43 of 12 (sleeves 120), partly covers the tobacco rod among the cigarette with filter tip FC.
At this constantly, as shown in Figure 6, attract pad 80 to connect with suction pump 92, thereby the air in the cigarette with filter tip FC is discharged through suction path 90 with suction pump 92 by being adjacent to pad 82.So, pressure converter 94 detect that negative pressure in the suction path 90b and extraneous gas import the differential pressure that produces between the negative pressure in the path 104 and the signal of this differential pressure of expression to controller 108 outputs.
Controller 108 based on from the signal determining differential pressure of pressure converter 94 input whether more than or equal to the decision threshold of regulation, here, if differential pressure is more than or equal to judging limit value, controller 108 just judges and takes place bonding badly on the scraps of paper of this cigarette with filter tip FC that just cigarette with filter tip FC might become cigarette without a head.At this moment, the signal of this cigarette with filter tip FC is got rid of in controller 108 outputs.On the contrary, when judging limit value, controller 108 just judges that this cigarette with filter tip FC is certified products in differential pressure, and just cigarette with filter tip FC can not become cigarette without a head.
If describe above-mentioned resolution principle in detail, when cigarette with filter tip FC passes through to check the position, sealed pad 60 sealings of the tobacco rod end of cigarette with filter tip FC.And be close to attraction pad 80 at the suction inlet of cigarette with filter tip FC.In addition, as shown in Figure 7, the punch column V of the scraps of paper of cigarette with filter tip FC is in the state by cut-out groove 122 sealings of the groove 74 of filter tip anchor clamps 72 and cut-out roller 10.
At this state, when by the air in the attraction pad 80 discharge cigarette with filter tip FC, if cigarette with filter tip FC is certified products, air just can not import in this cigarette with filter tip FC from the outside, and pressure converter 94 just can not detect more than or equal to the differential pressure of judging limit value.
, bonding when bad when existing on the scraps of paper of cigarette with filter tip FC, will badly between the scraps of paper and tobacco rod, produce the slit owing to this is bonding.At this moment, if discharge air in cigarette with filter tip FC, and make and press to negative pressure in the tobacco rod, this negative pressure will make above-mentioned slit enlarge.Therefore, the slit of this expansion makes the extraneous air that imports volume in the cigarette with filter tip FC, the result, and pressure converter 94 detects more than or equal to the differential pressure of judging limit value.So controller 108 can be checked the bonding bad of the scraps of paper reliably based on the signal of pressure converter 94 outputs.
During inspection, lid rolls 12 the lid groove 124 and groove 46 co-operatings of tobacco rod anchor clamps 43, partly covers the tobacco rod among the cigarette with filter tip FC.Therefore, even the coil paper of tobacco rod gas permeability more or less, lid rolls 12 also to be reduced by coil paper and imports extraneous air in the cigarette with filter tip FC, thereby pressure converter 94 can detect accurately because the differential pressure that cause in above-mentioned slit.
Because attract pad 80 not move at the axis direction of checking rotating cylinder 6, thereby attracting pad 80 to the suction path of suction pump 92 the volume change can not take place, this point is for improving above-mentioned inspection precision of great use from each.
Afterwards, cigarette with filter tip FC is checking on the rotating cylinder 6 that the rotating cylinder 8 that transports downstream moves.In this moving process, cam path 38 and cam follower 40 co-operatings make cigarette with filter tip FC and tobacco rod anchor clamps 43 together to leaving the direction motion that attracts pad 80.
Before cigarette with filter tip FC transported rotating cylinder 8 with arrival, sealing gasket 60 was drawn back by the tobacco rod end from cigarette with filter tip FC forcibly.That is, the cam follower 64 (with reference to Fig. 2) of sealing gasket 60 is fastened on the cam surface of edge cam 66, and edge cam 66 is by cam follower 64, and the elastic force of opposing compression helical spring 62 retracts the spacer rods 58 of sealing gasket 60.Thereby, even sealing gasket 60 is close to the tobacco rod end with the state of biting, also as illustrated in fig. 8 can be from this tobacco rod end reliable separation sealing gasket 60.
As a result, cigarette with filter tip FC can stably be transplanted on transporting on the rotating cylinder 8 of its downstream from inspection rotating cylinder 6 with sealing gasket 60 mutually noninterferes ground.Afterwards, sealing gasket 60 is compressed the elastic force of helical spring 62, turns back to position shown in Figure 4.In addition, reference marks S in Fig. 1
4The suction section of rotating cylinder 8 is transported in expression.
The present invention is not limited to an above-mentioned embodiment, can carry out various distortion.
For example, when on the scraps of paper of cigarette with filter tip FC, not establishing punch column as described above, can omit and cut off roller 10.
In addition, during inspection, it is whole that groove of tobacco rod anchor clamps 43 46 and lid roll the tobacco rod that 12 groove 124 also can cover among the cigarette with filter tip FC.
In addition, can carry out various variations to the concrete material and the shape of sealing gasket 60 and attraction pad 80.
