Make the device of shaft-like articles for use

Technical field

The present invention relates to a kind of device of from elongated material wire rod or material strips elongated line, making shaft-like articles for use, in particular for material from tobacco industry, it comprises a packing device that comes packing strips with packaging material, heating material bar or by the heater of the shaft-like articles for use of its manufacturing, and one preferably transported material strips or by the shaft-like articles for use of its manufacturing first conveyer by described device along y direction.

Background technology

In tobacco industry, this device is mainly as the filtering rod make-up machine part of filtering rod manufacturing usefulness.In filtering rod is made, the strip of filter material of extracting band for no reason out and be made of individual wire or fiber (for example cellulosic acetate) from package obtained processing before flocking together, form a filtering rod, pack with packing bar, its sealing area has adhesive tape, and is cut into the independent filtering rod of one or more use length.This process operation is to carry out as follows under actual state: after extracting out from bag, the filtering material tape leader utilizes air nozzle to unclamp earlier and launches, then elongation longitudinally in elongated region.With this understanding, the plasticizer that the filter material strip can be made line or fiber surface be clamminess is moistening, and bonding thereon.The band of purchasing so then flocks together, and forms a bar, packs and be cut into the filtering rod of one or more length available.

The above-mentioned plasticizer that is generally acetin forms the filtering material solvent.When plasticized dose of fiber surface was wetting, they began dissolved, and can be bonded on the contact position.Engage in order to solidify such fiber that forms, the plasticizer concentration in the filtering material of dissolving has to reduce.This can realize by plasticizer is dissolved in fibrous inside, thereby plasticizer is distributed in the material of huge amount, therefore obtains the dilution effect of wishing.Because most of employing chemical treatment, rate of dispersion depends on temperature, and temperature raises and causes quickening sclerosis.

Packing device has the conveyer belt of an annular circulation usually, is also referred to as form band (formatbolt), and the packaging material of material strips and separately supply can transport and pass through packing device along y direction by this band, and this is also referred to as form (format).In the case, strap is placed on around the material strips in the packing device by fixed-type instrument, and suitably coheres in position.

The sort of device that this specification the beginning part is mentioned can be learnt from US4357188A.In this known devices, filtering rod is by being subjected to the resonator of microwave energy effect.Under this state, filtering rod is directed to, and passes through resonator with the form band.Therefore by the sealing of form band, microwave works this filtering rod simultaneously.Only after the resonator launched microwave, the form band can be removed from filtering rod once more, then the packaged packaging material of going up of filtering rod.

A kind of identical device is disclosed among the DE2936490C2.

In order to prevent that the form by resonator is had harmful continuous heating, during form is brought swivel motion back to,, must cool off the form band, in DE2443056B2, being advised in the resonator outside.But should be noted that this measurement means the sizable attachment device expense of cost, especially merits no attention this scheme when considering manufacturing and maintenance cost.

Summary of the invention

The objective of the invention is to simplify the structure that this specification begins the device that part mentions.

The specific embodiment

The upstream that filtering rod machine 2 connects is a kind of processing unit (plant) (not shown), as described in DE4209606A1.In a kind of like this processing unit (plant), the filter material strip is extracted out from bag, and is main by launching and stretch and handle, and sprays equally distributed liquid plasticizer is arranged, as glyceryl triacetate.Sprinkling has the filtering material bar of acetin to convert strip at last in processing unit (plant), is bundled in together therein, or is collected, and then is transported to filtering rod machine 2.The filtering material bar that processing unit (plant) provides is shown schematically among Fig. 1, by Reference numeral 10 expressions.

Filtering material bar 10 then enters in the filtering rod machine 2 by input funnel 17, and being collected in therein together and being provided for from the packing bar 21 of spool 18 extractions and by adhesive means 19 provides thermosol.Packing bar 21 and the filtering material bar 10 that is collected in together run on the annular cycle format band 22, two kinds of materials of form band guiding are by packing device 23, packing device 23 will be packed bar 21 and be arranged on around the filtering material bar 10, therefore form a filtering rod 24 for no reason.The filtering rod 24 that has seam is by cooling rod 26, and cooling rod 26 is provided with and glueds joint seam.Then, with blade apparatus 27 filtering rod is cut down from filtering rod 24 continuously.Filtering rod is promoted by microwave applicator 28 along y direction, and is transported to by accelerator 29 and distributes in the drum 31, and is assigned with drum 31 and further transports along X direction.Filtering rod (not expressing in detail among Fig. 1) runs to zonation 32 from the distribution drum, then from being transfused to another Working position (also not expressing Fig. 1) here or being used for intermediate storage.

Relevant with microwave applicator 28 is a microwave generator 34 with whole control, and as microwave applicator, it also is arranged in the servicing unit 36.The information that this microwave generator 34 receives from the relevant filtering rod machine speed of service of control device 38, this control device is arranged in the filtering rod machine 2 in the embodiment shown, and control format tape drive 39, the microwave power that therefore its control produce.This form tape drive 39 drives annular cycle format band 22.

In the embodiment shown, accelerator 29 and distribute drum 31, and a part, and zonation 32 is by 40 sealings of first shell, the cornice of first shell 40 has heat insulation layer 40a, in order to prevent the too fast cooling of the filtering rod that is heated in microwave applicator 28.Perhaps for same purpose, this scheme can also have a device (not shown in figure 1) that first shell 40 is carried out air conditioning, particularly carries out air conditioning by the input hot-air.Also be provided with a temperature sensor 42 that connects microwave generator 34 in first shell 40, thereby the microwave energy that microwave generator 34 is produced by integral body control is in microwave applicator 28 inner control or be adjusted to a set-point, so that the filtering rod that will just transport by microwave applicator 28 is heated to fixed temperature.

Therefore, first shell 40 forms auxiliary connecting device 36 and filtering rod machine 2 downstreams or can become the distribution unit of servicing unit 36 parts.

Fig. 2 represents the more detailed side view that the part of microwave applicator 28 is decomposed, and Fig. 3 represents to be in closed condition, and (Fig. 3 a) and be in the cross sectional view of the microwave applicator 28 of open mode (Fig. 3 b).

This microwave applicator 28 has one second shell 50, and it can be opened by lid 50a.As shown in Figure 3, lid 50a forms the upper half shell part of second shell 50, can be pivotally opened, and fixing lower half shell portion is formed at second shell, 50 bottoms.Uncap 50a can provide the passage of the element that freely enters the inner and the inside installation of second shell 50.In service at microwave applicator 28, the lid 50a of second shell 50 is fastening by fixture 52.As shown in Figure 3, lid 50a is installed in by hinge 53 on the remainder of second shell 50, and wherein the pivot of hinge 53 extends in the longitudinal extent direction of second shell 50.Fig. 2 illustrates the almost whole length of extend through second shell 50 of lid 50a.

And for example shown in Figure 2, also have a safety switch 54, when second shell 50 was opened, safety switch cut off microwave generator 34 (Fig. 1) by the pivoting action of lid 50a.Therefore, safety switch 54 is connected on microwave generator 34 or the controller 38 (Fig. 1) by cable 54a.

At second shell, 50 1 ends an input pipe 56 is arranged, from blade apparatus 27 (Fig. 1) output, filtering rod is cut off filtering rod, and is separated into independent product, and delivers in the shell 50 of microwave applicator 28 by this pipe.Second shell, 50 opposite ends are provided with an efferent duct 57, pass efferent duct 57 at the filtering rod of microwave applicator 28 heating and run in the accelerator 29 that is connected the downstream (Fig. 1).As shown in Figure 2, input pipe 56 and efferent duct 57 are all directed vertically.

This microwave applicator 28 has a guider 60 that is arranged in second shell 50.In the embodiment shown, guider 60 is formed by three bars 61,62 and 63, and they are parallel to each other, and along the longitudinal extension of second shell 50.In the case, three guide posts 61,62,63 are stopping at input pipe 56 and efferent duct 57 front portions respectively, and extend along the common axle that is parallel to input pipe 56 and efferent duct 57.

Especially shown in Fig. 3 a, in the embodiment shown, first and second guide posts 61 and 62 form a pair of, and are arranged in the imaginary horizontal plane, and the 3rd guide post 63 is arranged on the central authorities above first and second guide posts.Therefore, first and second guide posts 61 and 62 form two following guide posts, and the 3rd guide post 63 forms one and goes up guide post.

Following first and second guide posts 61 and 62 are fixed on first support member 64, and this support member 64 is fixed on the standing part of second shell 50.On the contrary, the 3rd guide post 63 on top is fixed on second support member 66, and second support member 66 is fixed on second shell, the 50 lid 50a.The latter's result is that when lid 50a opened, the 3rd guide post 63 on top was removed, and removed from first and second guide posts 61 and 62 of bottom thus, shown in Fig. 3 b.

In the embodiment shown, three guide posts 61,62,63 all are arranged on the summit of imaginary equilateral triangle, and extend along the common axle of input pipe 56 and efferent duct 57.Therefore, 56, three spaced guide posts 61,62 of input pipe and 63 and efferent duct 57 between spacing form one and transport the path, filtering rod moves in the direction of the longitudinal axis along this path.

Therefore, three guide posts 61,62,63 form linear supported at three point and install, and in cross section, are that the supported at three point of point-like is installed perhaps.

In the case, the internal diameter of input pipe 56 and efferent duct 57 conforms to the external diameter of the filtering rod that will use.For the spacing between three guide posts 61,62 and 63, situation also is identical.

After passing through input pipe 56, filtering rod runs on first and second guide posts 61,62 of two bottoms, and slides along them, leaves microwave applicator 28 by efferent duct 57 once more up to them.Along first and second guide posts 61 with between 62 moving periods, top the 3rd guide post 63 that is arranged on above them guarantees that filtering rod does not leave bottom first and second guide posts 61 and 62 paths that form at them.Therefore, first and second guide posts 61 and 62 of bottom are used as support, and the 3rd guide post 63 on top is used as the upper limit border of transporting the path of such formation.Spacing between these three guide posts 61,62 and 63 is chosen as filtering rod is moved along y direction with only having suitable little clearance, and the spacing between first and second guide posts 61 and 62 of its middle and lower part is less than the diameter of filtering rod.

As shown in Figure 3, these three guide posts 61,62 and 63 all have circular cross section.Consequently in fact only form linear support on first and second guide posts 61 and 62 of bottom, same the 3rd guide post 63 on top in fact only contacts with the linearity of filtering rod.Like this, filtering rod and guide post 61,62, contact between 63 and the friction that is produced between them reduce.In addition, the filtering rod that enters by input pipe 56 can be oriented such that glueing joint seam does not contact guide post 61,62 and 63, is arranged between them but also can be oriented.

In the embodiment shown, the transmission driver that initiatively transmits filtering rod is not set in microwave applicator 28.On the contrary, the kinetic energy that has entered the filtering rod in the input pipe 56 must be enough to make filtering rod to slide through input pipe 56 rapidly, also arrives in the accelerators 29 (Fig. 1) by efferent duct 57 along guide post 61,62 and 63.Therefore, input pipe 56, guide post 61,62 and 63 and efferent duct 57 should make by low friction material.Owing to add thermal effect, the material of three guide posts 61,62,63 and the material of efferent duct 57 also should be heat-resisting, and for example ceramic material is suitable as this purpose.
