With reference to the Fig. 1 in all accompanying drawings, label 1 integrally represents to be used for the part cigarette with filter tip manufacturing, that be referred to as the machine of filter tip attachment.The infeed 2 of attachment is connected in the outlet 3 of a beam 4, cigarette 5 from the Double Length of beam 4, guided into the infeed 2 of attachment continuously by a delivery unit 6, attachment is made up of a series of rollers that rotate around axis parallel to each other as seen from the figure, and each roller is equipped with a plurality of suction grooves.For simplicity, except with the concrete Digital ID, roller is commonly designated as R, and all grooves are denoted as 8.

Infeed 2 is corresponding with first roller 7, roller 7 as shown in Figure 1 along clockwise direction, the axis of the correspondence of extending around the Control Shaft that is parallel to beam 4 rotates with constant angular speed, by roller 7, the cigarette 5 of Double Length is received in the groove 8 that is parallel to turning cylinder.So cigarette 5 advances transverse to its longitudinal axis, and corresponding groove 8, the second rollers 9 that in turn are sent to the periphery by second roller 9 and provide rotate as shown in Figure 1 in the counterclockwise direction.

The cigarette 5 of Double Length is carried by second roller 9, and once more transverse to its axis, towards a cutting unit 10, each cigarette is cut in a conventional manner and forms two single cigarette 5a at this, and the length of single cigarette is corresponding to the length of regular-size cigarette; Then, two cigarette 5a alignment direction vertically advance, and are sent in the groove 8 of the 3rd roller 11 that rotates along clockwise direction, and they axially separate mutually on the 3rd roller.

The cigarette 5a that separates is sent on one the 4th roller 12, and the 4th roller is a part of tradition assembling station 13, and the assembling station comprises that also one transmits the feeding roller 14 of Double Length filter tip stopper 15.As Fig. 1 finding, feeding roller 14 is positioned to tangent with the 4th roller 12 basically, rotate in opposite direction with same peripheral speed, and be designed to the filter tip stopper 15 of the Double Length that each is continuous, the middle body of the corresponding groove that provides by the 4th roller 12 is provided.Be sent to each stopper 15 of the corresponding groove 8 of the 4th roller 12 thus, be positioned between two single cigarette 5a that are sent in the same groove 8 being rendered as, and align with two single cigarette, like this, form an assembly 5b on roller 12, this assembly is made up of two cigarette 5a that axially align, separated by the filter tip stopper 15 of a double-length degree.Then, these assemblies 5b one after the other is transported to the 5th roller 16 from the 4th roller 12, the disclosed infeed station that becomes article unit 17 with the type of advocating is consistent among the 5th roller 16 and the italian patent n ° 1 200 229, for trying to achieve comprehensive introduction, and can be with reference to this italian patent.

Except the 5th roller 16 as shown in Figure 1, finish station 17 and also comprise a feeding roller 18, it is positioned to supply with the coated papers of being separated from a continuous paper tape 20 by cutter unit 21 19, the effect of coated papers is, the filter tip stopper 15 of two cigarette 5a and Double Length is linked together, to be combined into an assembly 5b.Form a rolling unit 22 in addition of the part of this end station 17, it comprises the roller 23 of a correspondence, this roller is designed to be used for to admit the coated papers 19 together with correspondence from each continuous assembly 5b of the 5th roller 16, then, rolling coated papers 19, be wound on the filter tip stopper 15 of Double Length and the end of the correspondence of two cigarette 5a, thereby form the cigarette of a double-length degree, indicate with label 5c.The cigarette 5c of Double Length is corresponding with the outlet that becomes article unit 17 by delivering to one the 6th roller, 24, the six rollers continuously from parcel roller 23.

On a set point of the groove 8 that occupies the 6th roller 24, the cigarette 5c of the Double Length that each is continuous is conducted through a cutting unit 25, this cell location becomes to engage with the filter tip stopper 15 of Double Length, like this, produce the corresponding paired single cigarette of axially aligning 26, then, cigarette 26 is sent to other roller 27 and 28 from this roller 24, from then on is transported to other all machining cell of this filter tip attachment of schematically being represented by a square 29.One of all steps of being implemented by these other unit are to line up the cigarette after the cutting single-row.

Fig. 2,3 and 7 illustrate the part of a typical roller R, and roller R demonstrates corresponding groove 8, and each groove presents the arcuate profile of the concave surface that has the pivot center that deviates from roller R.More accurately, groove 8 is formed with two sides 30 relative to each other that are connected with basal surface 31, and at least two holes 32 are provided, and hole 32 is connected to a negative pressure source (therefore traditional implementation method does not give illustrating) by means of conduit 33 radially.

Show that as understanding already each groove 8 of given roller R is used for holding the cigarette 5 of a double-length degree, or a single cigarette 5a, or by by filter tip stopper 15 separated two assembly 5c that single cigarette 5a forms of a double-length degree; Yet, for simplicity, hereinafter will simply it be mentioned being cigarette 26.

In particular with reference to Fig. 3, two sides 30 are flat straight lines, like this, groove 8 presents the cross section of roughly shallow " U " shape, groove 8 is balanced (see figure 3)s, so that corresponding cigarette 26 is shelved: two longitudinal regions 34 of its cylindrical surface contact with two of side 30 corresponding longitudinal regions, by this way, at the basal surface 31 of groove 8 with between the part 26a of the cylindrical surface of the cigarette 26 of this basal surface 31, form at least one chamber 35.Therefore, chamber 35 is enclosed between following two parts, and the one, the part of the cylindrical surface of the cigarette 26 that limits by the longitudinal region 34 of two contacts, another is the part on the surface of the groove 8 that limited by same two contact areas 34.

Chamber 35 is connected to above-mentioned negative pressure source by the hole 32 of correspondence, from Fig. 7 as seen, hole 32 is positioned at the position near two opposite ends of groove 8, like this, than two outermost portions, it is stronger that the parital vacuum that produces in chamber 35 will be inhaled the middle body that extends between the hole 32 at two; Therefore, in the face of the part of the cigarette 26 of maximum suction, correspondingly will be that part of of the cylindrical surface part 26a that between two holes 32, extends.

In the example of Fig. 8 and 9, two sides 30 of each groove 8 are connected on the basal surface 36 that presents square cross section, groove 8 be included in perpendicular to bottom surface 37 and and two sidewalls 38 merging of side 30 between the bottom surface 37 of extending.Amplified at this example lumen 35, and between cigarette 26 and side 30, still keep as identical contact as described in first example, the distance that the part 26a of the cylindrical surface of cigarette 26 and the bottom surface of groove 37 separate increases, like this, if tobacco filament pitches from the termination of cigarette 26, then this can not cause the loss of any chucking power between cigarette 26 and the side 30.

Figure 10, groove 8 shown in 11 and 12 is formed with a basal surface 39, it presents a rib 40 longitudinally, rib 40 is positioned to contact with intermediate strap 26b on the part 26a of the cylindrical surface of the cigarette 26 of basal surface 39, and forms two and half chamber 35a as shown in figure 10 with this part 26a combination of cylindrical surface.Observe Figure 12 especially, described rib 40 has transverse groove 41, and it is corresponding with suction hole 32, and hole 32 is communicated with two and half chamber 35a by this groove 41.

Fig. 4,5 and 6 illustrate all steps that a cigarette transmits, and in the part 1 of machine shown in Figure 1, from a typical roller R that discharges, it rotates along clockwise direction and is shown in the left side at three figure middle fingers, and to a typical roller R that receives, it rotates in the counterclockwise direction.More accurately, Fig. 4 illustrates the mutual alignment that two grooves 8 discharge respectively and receive, and just the moment before from left to right shifting, wherein, cigarette 26 is held by the parital vacuum that the chamber 35 of the groove 8 that is presented by release roller R produces.Fig. 5 illustrates the same mutual alignment of two grooves 8 in transfer step process thereafter, wherein, when roller R when separately axis rotates, along corresponding longitudinal region 34, and by a predetermined angle distance (being generally 6 °), cigarette 26 still keeps synchronously contacting with two sides 30 of release groove and two sides 30 of receiving slit 8.Therefore, cigarette 26 synchronously contacts with four sides 30 of two corresponding grooves 8 along the longitudinal region 34 of its four cylindrical surfaces.

A certain set point in the convey program process at first stops to activate suction in the chamber 35 of release groove 8, by means of traditional valve gear (do not give among the figure and illustrating), synchronously activate the suction in the chamber 35 of receiving slit 8.Like this, cigarette 26 transfer (it is ended as shown in Figure 6) of 8 from release groove 8 to receiving slit can realize step by step that can't cause ordering about the radially leap of cigarette 26 between two grooves 8, in any case, groove can damage cigarette.

In order to ensure transferring to the Next whole operation from a roller R in realization, correctly control the position (especially as seen from Figure 5) of cigarette 26, by discharging the oblique relative paired side 30 that has respectively with receiving slit 8, by more or less less than the distance of the diameter of single cigarette 26 and separated from each other, like this, this cigarette will be subjected to slight compressing at four longitudinal regions 34 that contact with four corresponding surfaces 30.

Groove at two adjacent roller R shows as Figure 10, in the situation of 11 and 12 example, cigarette 26 will not only be held along above-mentioned four longitudinal regions 34 that contact in transfer step, and the part 26b that the edge contacts with rib 40 is held, like this, between cylindrical surface and groove, six contact points are arranged, wherein four with 30 longitudinal region 34 is corresponding along the side, and other two zones 42 with the rib 40 that offers cigarette 26 are corresponding.

In the example of Figure 13 and 14, the side 30 of each groove 8 is connected on the basal surface 39 that presents square cross section, and groove 8 comprises a flat bottom surface 43 and two sidewalls 44 that are substantially perpendicular to bottom surface 43.Therefore, this solution is similar to the scheme shown in Fig. 8 and 9, but difference only is that the cigarette 26 that provides both contacted with two sides 30, also contacts with planar base surface 43, thus, forms two and half chamber 35a.Each hole 32 has the countersunk mouth 45 that is communicated with two and half chamber 35a.

In the example of Fig. 7 to 14, can see that two opposite ends of groove 8 both can be implemented as shown in Figure 3, also can implement with the mode that part 46 is familiar with like that, the shape that part 46 is made makes any suction losses from

chamber

35 or 35a be reduced to minimum.At Figure 15, in 16 and 17 the example, the end shape of groove 8 can make cigarette 26 engage fully contiguously with part 46 between two sides 30.

At last, in the example of Figure 18 to 21, single groove 8 forms in this manner: the cigarette 26 that is positioned on the basal surface 48 only contacts with the zone 49 of approximate centre.Described central area 49 is between two grooves 50 that presented by basal surface 48, and two grooves extend on the total length of groove 8 practically.The purposes of groove 50 is to set up two and half chamber 47a of a chamber (whole label is 47), and this chamber 47 forms between the cylindrical surface of basal surface 48 and cigarette 26.Connection between chamber 47 and the above-mentioned negative pressure source is to be provided by the holes 32 in the basal surface 48, and this hole is positioned to consistent with the middle section 49 that contacts.Each hole 32 presents a countersunk mouth 52 that is communicated with two grooves 50.

Groove 50 can be different cross section form: the example of Figure 18 illustrates a square cross section that is similar to Figure 13, and the example of Figure 20 illustrates one and is similar to Figure 10,11 and 12 arc.

Can see that from the example of Figure 18 to 21 parital vacuum is formed in the chamber 47, be different from chamber 35, it has open side.Therefore, in this example, two end parts 46 that comprise in the above described manner will be favourable especially, for this reason, farthest reduce the loss of the suction from chamber 47.
