Description

Setup device to guide the packaging web into the rod making machine

Technical field

[0001] The present invention relates to a rod manufacturing machine, that is, a setup device that guides a packaging web through the lapping device before a smoking rod such as a cigarette rod or a filter rod is manufactured by the rod manufacturing machine.

Background art

[0002] A composite filter is known as a filter for a cigarette, and the composite filter includes a plurality of types of cylindrical filter elements. For example, when the composite filter is a dual filter, the dual filter includes a plain filter element and a charcoal filter element, and these filter elements are integrally connected by a molding paper.

[0003] A rod manufacturing machine for manufacturing the dual filter described above is disclosed in, for example, Japanese Patent Application Laid-Open No. 2003-24035. The rod making machine of this publication first forms an element column continuously, this element column including alternating plain filter elements and charcoal filter elements. Such element columns are supplied with the packaging web to the lapping machine of the rod making machine. The wrapping device continuously wraps the element column with the packaging web to form a composite element rod, and the formed composite element rod is delivered by the wrapping device force. Thereafter, the composite element rods are cut into predetermined lengths and formed into individual composite filter rods.

[0004] In addition, the composite filter rod is fed to a rod making machine force filter attachment machine, which produces a filter cigarette from the composite filter rod and cigarette rod.

In order to increase the productivity of the composite filter rod described above, the technology of a cigarette manufacturing machine disclosed in Japanese Patent Laid-Open No. 8-205842 can be applied to the above-described rod manufacturing machine. The cigarette manufacturing machine disclosed in the publication includes a duplex forming path, and cigarette rods are manufactured through the respective forming paths.

[0006] Preparation for starting the rod making machine is performed by passing the packaging web through the wrapping apparatus. Including picking up work. However, since various molding guides and devices essential for molding the composite filter rod are arranged on the molding path of the wrapping device, these molding guides and devices are arranged before the packaging web is set up. Forming path of upper force Must be retracted. For this reason, it is not easy to set up the packaging web. Specifically, the forming guide and the device are supported by the wrapping device so as to be rotatable between an operating position on the forming path and a retracted position positioned behind the wrapping device.

[0007] In particular, in the case of a wrapping apparatus having a duplicated molding path, even if two molding paths are opened, the rear-side molding path is not greatly opened compared to the front-side molding path. It is difficult to set up the packaging web.

Disclosure of the invention

Problems to be solved by the invention

[0008] It is an object of the present invention to provide a setup device that can easily guide a packaging web into a wrapping device prior to starting a rod manufacturing machine.

[0009] A rod manufacturing machine to which the present invention is applied has a forming path, a guide path disposed in the vicinity of the starting end of the forming path, and a web path for supplying a packaging web to the forming path via the guide roller. , A wrapping device including a supply device that feeds a filling member through a guide roller toward the forming path, superimposes the filling member on the packaging web in the forming path, and a guillata tape that runs along the forming path And a wrapping device for continuously forming the rod encased by the packaging web when the filling member and the packaging web pass along the molding path by the travel of the guillotine tape.

[0010] The setup device of the present invention is an introduction line that guides the packaging web toward the forming path when preparing to start the rod manufacturing machine, and an upstream path that guides the packaging web upstream of the guide rollers. An introduction line having a downstream path for guiding the packaging web together with the filling member downstream from the guide roller, a holding means disposed in the upstream path and releasably holding the leading end of the packaging web, A delivery means for delivering the packaging web toward the guide roller when the leading end is released; and a guidance means for forming a tunnel-shaped guide passage at the end of the upstream path, when delivering the packaging web , Guide the tip of the packaging web Guide means that guides to the guide roller through the passage and sandwiches the leading end of the packaging web between the guide roller and the filling member, and when the filling member and the packaging web pass on the downstream path, these filling members And a pressurizing means for increasing the adhesion of the packaging web.

[0011] According to the setup apparatus described above, before the operation of the rod manufacturing machine is started, the leading end of the packaging web is held by the holding means and stands by in the upstream path of the introduction line. In this standby state, the supply of the filling member toward the wrapping apparatus is started. Thereafter, the leading end of the packaging web is released, and at the same time, the packaging web is delivered toward the guide roller by the delivery means.

[0012] The leading end of the delivered packaging web enters the tunnel-shaped guide passage, and is guided to the guide roller while being guided in the guide passage. When the leading end of the packaging web reaches the guide roller, the leading end of the packaging web is sandwiched between the guide roller and the filling member, and is drawn into the downstream path of the introduction line together with the filling member.

[0013] At the timing when the packaging web is retracted, the pressurizing means increases the adhesion between the packaging web and the filling member, whereby the packaging web reliably advances in the downstream path together with the filling member, and is wrapped. Delivered into the device. Thereafter, the filling member and the packaging web pass through the wrapping apparatus by the travel of the guillotine tape, and the packaging web setup work is completed.

As a result, the packaging web can be automatically guided through the wrapping apparatus without opening the molding path in the wrapping apparatus.

[0015] Specifically, the downstream path includes two guide walls that sandwich the filling member and the packaging web, and guide the filling member and the packaging web toward the molding path. The guide wall is pressed against one of the filling member and the packaging web. In this case, the one guide wall preferably forms the bottom wall of the downstream path that can be displaced vertically, and the pressurizing means includes a push-up mechanism that pushes the bottom wall upward. Such a push-up mechanism can include a spring that biases the bottom wall downward, and a wedge member that pushes the bottom wall upward against the biasing force of the spring.

[0016] Further, the delivery means is an air that blows out air toward the guide passage when the packaging web is delivered. Including the nozzle! / The air blown out from the air nozzle, which is preferable to be guided, reliably guides the leading end of the packaging web to the guide passage.

[0017] Specifically, the delivery means is disposed near the upstream path and positioned upstream of the guide path, with the upstream path sandwiched between the first roller, A roller holder that is rotatable between a preparation position and an operating position, and has a roller holder having an end close to the guide path when the roller holder is in the operating position, and a roller holder provided on the roller holder. When the holder is in the operating position, the holder may include a second roller that sandwiches the packaging web with the first roller, and a motor that rotates at least one of the first and second rollers.

[0018] Only when the packaging web is delivered, the first and second rollers sandwich the packaging web, while the first and second rollers also separate the web path force during operation of the rod making machine. ing. Therefore, the first and second rollers do not interfere with the travel of the packaging web during operation of the rod making machine.

[0019] When the delivery means includes the roller holder described above, the holding means may include an adsorption surface that is provided at one end of the roller holder and releasably adsorbs the leading end of the packaging web. Further, the air nozzle may be an air ejection hole provided at the tip of the roller holder, and the air ejection hole blows air toward the guide passage when the roller holder is in the operating position.

[0020] Furthermore, the supply device of the rod manufacturing machine can supply a plurality of types of filter elements as the filling member in the rod-shaped element column arranged in a line in a fixed arrangement pattern. Further, when the rod manufacturing machine has a pair of molding paths, the setup device has an introduction line for each molding path.

These conveyors 18 are arranged in parallel with the rows of hoppers 16a to 16d. The front competitor 18f extends from the hopper 16a to the hopper 16d. On the other hand, the rear conveyor 18r is disposed between the front conveyor 18f and the row of hoppers 16 and extends from the hopper 16a to the hopper 16b.

[0025] The front and rear conveyors 18f and 18r have endless succession belts 22f and 22r, respectively. These suction belts 22f and 22r are respectively wound around drive rollers 24, and these drive rollers 24 are positioned at the ends of the front and rear conveyors 18f and 18r. Yes. When the drive rollers 24 are rotated, the succinct belts 22f and 22r travel in the same direction and at the same speed. Suction chambers (not shown) are arranged in the front and rear conveyors 18f and 18r, respectively, and these suction chambers supply a predetermined suction pressure to the suction belts 22f and 22r.

[0026] The hopper device 12 includes element feeders 26a and 26b for supplying the planes and the charcoal rods F and F in the hoppers 16a and 16b toward the rear conveyor 18r, and the front conveyor 1

And feeding element feeders 26c and 26d. These element feeders 26a to 26d are also arranged in the arrangement direction of the hoppers 16a to 16d.

[0027] The element feeders 26a to 26d have substantially the same structure. Therefore, only the structure of the element feeder 26a will be described below, and for the other element feeders 26b to 26d, the same parts and members as those of the element feeder 26a in FIG. The explanation is omitted.

[0028] The element feeder 26a includes a take-out drum 28. The take-out drum 28 is disposed immediately below the hopper 16a, and the outlet of the hopper 16a is covered with a lower force by the outer peripheral surface thereof. A number of grooves (not shown) are formed on the outer peripheral surface of the take-out drum 28, and these grooves are arranged at equal intervals in the circumferential direction of the take-out drum 28. When the grooves of the take-out drum 28 are at the outlet of the hopper 16a, these grooves receive the plain rod F in the hopper 16a one by one, and

In this state, the hoppers 16a are taken out one by one and transferred along the outer peripheral surface of the take-out drum 28.

[0029] The take-out drum 28 further includes a plurality of rotary knives 30 on the outer peripheral surface thereof. As the plain rod F passes through the rotary knife 30 in sequence while the plane rod F is being transferred, this

[0030] A chain conveyor (not shown!) Is disposed immediately below the take-out drum 28, and this chain conveyor extends horizontally from the take-out drum 28 toward the rear conveyor 18r. Choi The conveyor has a plurality of extrusion claws, and these extrusion claws are arranged at predetermined intervals in the running direction of the chain conveyor. While the chain conveyor is running, when one groove of the take-out drum 28 reaches directly above the chain conveyor, one extrusion claw of the chain conveyor passes through the groove. Therefore, the plain rod F in the groove of the take-out drum 28 (each other

Is arranged. An arcuate delivery path is formed outside the delivery wheel 32, and this delivery path connects between the acceleration path and the rear conveyor 18r.

[0033] When the plain rod F on the chain conveyor enters the acceleration path, the plain rod F

Not shown). The accelerating conveyor is located above the chain conveyor and runs faster and faster than the chain conveyor.

On the other hand, the delivery wheel 32 has a plurality of delivery claws 34 on its outer peripheral surface, and these delivery claws 34 are arranged at equal intervals in the circumferential direction of the delivery wheel 32. Accordingly, with the rotation of the delivery wheel 32, each delivery claw 34 is pushed out into the acceleration path force delivery path and sequentially enters between the filter elements f in the separated state, and the filter elements f are moved into the rear conveyor 18r.

, 38r extend horizontally, coaxially with the front and rear conveyors 18f, 18r, respectively, and pass through the rubbing device 36, respectively.

[0041] The wrapping device 36 has the same structure for each of the front and rear molding paths. Therefore, the structure of the wrapping device 36 that forms a pair with one molding path will be described below.

[0042] The wrapping device 36 includes an endless gusset tape 40, which extends horizontally in a forming groove of a forming bed (not shown). The forming groove forms part of the forming path 38. The guillotine tape 40 is wound around the drive drum 42, and the drive drum When 42 is rotated, the guillotine tape 40 travels in the same direction as the traveling direction of the corresponding conveyor 18, that is, the suction belt 22. However, the traveling speed of the guillotine tape 40 is slower than the traveling speed of the suction belt 22. For example, the running speed of the sachet belt 22 is set to 1.4 times the running speed of the guillotine tape 40. The drive drum 42 is commonly used for the gutta tape 42 in the front and rear molding paths.

[0043] A guide roller 44 is rotatably disposed between the guillotine tape 40 and the corresponding conveyor 18, and the guide roller 44 guides the packaging web W and forms a molding path 38, that is, a garment. Lead on top of the tape 40. The wrapping web W is unwound from a web roll (not shown) and guided to the guide roller 44 along the web path.

[0044] When the element stream is supplied from the conveyor 18 on the side corresponding to the guillotine tape 40, the element stream is transferred onto the guillotine tape 40 via the wrapping web W, and thereafter, the gature tape 40 and the wrapping tape. Drive with Web W.

[0045] As described above, the traveling speed of the guillotine tape 40 is slower than the traveling speed of the conveyor 18 (the sachet belt 22), and the wrapping device 36 includes a braking tunnel (not shown) at the beginning of the forming path 38. It is out. Thus, when the element stream supplied from the conveyor 18 onto the forming path 38 passes through the braking tunnel, the individual filter elements f of the element stream are braked in the braking tunnel. As a result, the element stream is the individual filter material f, f

Are formed in a bar-shaped composite element column C (see Fig. 2) that are in close contact with each other.

C E

Column C extends across the end of the brake tunnel conveyor 18.

[0046] In the process in which the packaging web W is supplied toward the guillotine tape 40, rail glue is applied to the center of the packaging web W. Therefore, when an element stream, i.e., composite element column C, is supplied on the packaging web W, the composite element column C is wrapped with rail glue.

E E

Overlaid on Eb W. At this point, however, the rail glue does not completely bond each filter element f of the composite element column C to the packaging web W.

E

Is allowed to slide on the packaging web W, which allows the formation of a composite element column C

E

It has become.

[0047] After this, the composite element column C is moved along with the packaging web W by the running of the guillata tape 42. It is transferred on the molding path 38.

[0048] In this transfer process, the composite element column C is packed by the former of the wrapping device 36.

E

Wrapped in web W and molded into composite element rod ER. The formed composite element rod ER is delivered from the lapping device 36 along the forming path 38.

[0049] In Fig. 2, the packaging web W of the composite element rod ER is not shown, and the braking tunnel and former of the wrapping device 36 will be described later.

[0050] A cutting device 46 is disposed downstream of the wrapping device 36. As the composite element rod ER passes through the cutting device 46, the cutting device 46 cuts the composite element rod ER by a predetermined length to form individual filter rods FR. Specifically, the cutting device 46 includes a knife rotor 48 that can rotate in one direction, and a plurality of knives 50 are attached to the outer peripheral surface of the knife rotor 48 at equal intervals in the circumferential direction! / RU As the knife rotor 48 rotates, these knives 50 periodically cut the composite element rod ER to form the composite element rod ER force individual filter rods FR.

[0051] As is apparent from FIG. 2, the filter rod FR is a Cyacol element f in the composite element rod ER.

Obtained by cutting one or more C at a time, and therefore, at each end thereof, a charcoal element f

Each has a half of C.

[0052] As is apparent from FIG. 2, a cutting device 46 or knife rotor 48 is commonly used for the composite element rod ER on the front and rear forming paths 38f, 38r, each knife 50 being both composite elements. Cut the rod ER continuously. The cutting device 46 has guide sleeves 52 for guiding the composite element rod ER on the front and rear molding paths 38f and 38r, respectively, and these guide sleeves 52 allow the knife 50 to pass therethrough.

[0053] Furthermore, kickers 54f and 54r are disposed at the ends of the front and rear molding paths 38f and 38r, respectively, immediately above the ends. These kickers 54 have a rotatable roller and a spiral groove (not shown) formed on the outer peripheral surface of the roller. When the leading filter rod FR on the forming path 38 reaches the corresponding kicker 54, the filter rod FR enters the spiral groove of the kicker 54, and the rotation of the kicker 54 causes the subsequent filter on the forming path 38 to follow. The filter rod FR force is also separated and the end force of the forming path 38 is kicked out.

[0054] In this way, the end forces of the front and rear molding paths 38f and 38r were also kicked out, respectively. The filter rod FR is received by a common receiving drum 56. More specifically, the receiving drum 56 is rotatably supported and has a large number of receiving grooves (not shown) on its outer peripheral surface. These receiving grooves are arranged at equal intervals in the circumferential direction of the receiving drum 56, and can receive the filter rod FR kicked out from each forming path 38 every other groove. Therefore, the filter rod FR from which the end forces of the front and rear molding paths 38f and 38r are kicked out by this is alternately arranged on the receiving drum 56 in the circumferential direction of the receiving drum 56.

[0055] A transfer drum row 58 extends from the receiving drum 56, and the transfer drum row 58 includes a plurality of rotatable transfer drums. These transfer drums are grooved drums similar to the receiving drum 56. The filter rod FR on the receiving drum 56 is received by the transfer drum 58, and the transfer drum row 58 transfers the received filter rod FR to the belt conveyor. The belt conveyor extends toward a boxing machine (not shown) and supplies the filter FR received from the transfer drum row 58 to the boxing machine.

[0056] Referring to FIG. 3, the structure of the wrapping apparatus 36 paired with one molding path 38 is shown more specifically. The wrapping device 36 includes a front tongue 60, a rear tongue 62, a short holder 64, a long holder 68, and a cooler 70, which are sequentially arranged from the upstream side of the molding path 38.

[0057] The front tongue 60 is disposed at the start end of the forming path 38, that is, immediately downstream of the guide roller 44 described above. The rear tongue 62 is disposed at a predetermined interval from the front tongue 60, and air nozzles 72 are disposed immediately downstream of the tongues 60 and 62, respectively.

[0058] The front and rear tongs 60, 62 cooperate with the forming grooves of the forming bed to form braking tunnels through which the element streams described above pass, respectively, and these braking tunnels are filter elements f, f of the element streams. To form a composite element column C. Compound element column C

When the composite element column C comes out of the corresponding tongue, each air nozzle 72 is

The compressed air is blown onto the elementary column C, and a braking force is further applied to the composite element column C.

[0059] The short holder 64 and the long holder 68 sequentially bend both side edges of the packaging web W along the outer peripheral surface of the composite element column C, whereby the composite element column C is wrapped in the packaging web W.

E E

Expected. A glue applicator 66 is disposed in the vicinity of the short holder 64, and this glue applicator 66 has a glue nozzle 74 corresponding to each molding path 38 as shown in FIG. These glues The glue 74 applies wrap glue to one side edge of the corresponding packaging web W. Therefore, when the packaging web W wraps the composite element column C, the side edges of the packaging web W

Are bonded to each other. After this, when composite element column C passes cooler 70,

E

The roller 70 cools the wrap paste and rail paste applied to the packaging web W, respectively, and promotes the solidification of the wrap paste and rail paste. As a result, the adhesive force between the packaging web W and the composite element column CE and between both side edges of the packaging web W is increased.

Further, FIG. 3 also shows an exchange device 76 for the guillotine tape 40, and this exchange device 76 is arranged in the vicinity of the drive drum 42.

[0061] The exchange device 76 includes a V-shaped link 78, and the V-shaped link 78 has one proximal end and two distal ends. The base end of the V-shaped link 78 is rotatably supported. A tension roller 80 is rotatably attached to one end of the V-shaped link 78, and the packaging web W is passed around the tension roller 80 by being wound around the tension roller 80. An air cylinder 82 is connected to the other end of the V-shaped link 78. When the air cylinder 82 is contracted as shown, the tension roller 80 moves upward via the V-shaped link 78 and releases the tension of the galactic tape 40. Therefore, the guillotine tape 40 can easily remove the driving drum 42 and a large number of guide roller forces.

FIG. 5 shows a downstream portion of the web path that guides the packaging web W to the guide roller 44.

[0063] A pooling roller 84 and a pinch roller 86 are arranged in the web path. These rollers 84 and 86 are commonly used for the respective packaging webs W supplied to the front and rear molding paths 38f and 38r, respectively, and these packaging webs W pass between the pooling roller 84 and the pinch roller 86. To do. A buffer lever 88 with a roller is disposed upstream of the pooling roller 84, and a swing lever 90 with a roller is disposed downstream of the pooling roller 84. Further, a suction brake 92 is arranged downstream of the swing lever 90. The buffer lever 88 and the brake 92 are provided independently for each packaging web W. The swing lever 90 is commonly used for each packaging web W.

[0064] Further, a glue application nozzle 94 is disposed for each packaging web W downstream of the succession brake 92. These glue application nozzles 94 are provided on the corresponding packaging web W as described above. Apply rail glue.

[0065] During the operation of the rod manufacturing machine, the above-described pooling roller 84 has a speed corresponding to the operating speed of the rod manufacturing machine (traveling speed of the governor tape 40), and the forming path 38 on the corresponding side of each packaging web W. Supply towards

A setup device 96 is disposed in the vicinity of the downstream end of the web path, that is, in the vicinity of the guide roller 44 described above. This setup device 96 is simply shown as a block in FIGS. 2, 3 and 5, but when setting up the rod manufacturing machine, that is, when it is ready to start, a new packaging web is placed in the corresponding forming path. Along the wrapping device 36.

The details of the setup device 96 are shown in FIGS. 6 to 12. The setup device 96 will be described below with reference to these drawings.

Further, a bottom guide 162 is disposed between the guide roller 44 and the starting end of the forming path 38 (roller that guides the guillotine tape 40). This bottom guide 162 has a common upper surface 162a for the front and rear molding paths 38f, 38r. This upper surface 162a is the top of the guillotine tape 40, the guide roller 44, and the above-described molding path 38. It is positioned at the same level as the upper surface of the conveyor 18 and extends from the guide roller 44 to the starting end of the forming path 38.

As is clear from FIG. 6, the bottom guide 162 cooperates with the above-described front tongue 60 to form an introduction passage 164 from the guide roller 44 to the forming passage 38 (braking tunnel). That is, the bottom guide 162 becomes the bottom wall of the introduction passage 164.

[0084] For ease of drawing, the front tongue 60 of FIG. 6 is simply shown as the ceiling wall (guide wall) of the introduction passage 164. As shown in FIG. 6, the introduction passage 164 may extend the guide roller 44 force to the end of the conveyor 18. In this case, the upper guide 166 is disposed upstream of the front tongue 60, and the lower guide 168 is disposed between the upper end of the guide cover 152 and the end of the competitor 18 described above.

The above-described bottom guide 162 is supported by a push-up device 169, and this push-up device can displace the bottom guide 162 up and down. The push-up device will be described in detail below.

[0086] As is clear from FIG. 6, the bottom guide 162 has a leg 170, and the leg 170 extends downward. The lower end of the leg 170 is sandwiched between the support plate 172 and the back plate 174. These plates 172, 174 are connected to each other. The support plate 172 is disposed between the leg portion 170 of the bottom guide 162 and the web guide 144 described above, and is supported by the frame 98.

When the piston rod 194 of the air cylinder 192 is slightly extended in the rest position force, the support port 184 moves slightly to the right with the wedge member 182 as viewed in FIG. Such movement of the wedge member 182 displaces the bottom guide 162 upward. Thereafter, when the piston rod 194 is returned to the rest position, the bottom guide 162 is returned to the original position by the urging force of the tension coil spring 180.

Next, a setup operation for a pair of packaging webs by the setup device 96 will be described.

Since the pair of packaging webs is supplied to the wrapping device 36 in the same manner, In the following description, attention is paid to one of the packaging webs.

[0094] When the rod manufacturing machine is prepared for starting, the movable roller holder 118 and the guide cover 152 are in the same state as when the rod manufacturing machine is in operation. That is, the movable roller holder 118 is positioned at a horizontal preparation position, and the guide cover 152 is positioned at a rest position where the web guide 144 force is also separated.

[0095] In this state, the packaging web W1 to be supplied to the forming path 38 is guided to the movable roller holder 118 through the web path. Further, the leading end of the packaging web W1 passes through the pinch roller 122 of the movable roller holder 118 and is positioned in the corresponding suction region 124 of the holding surface 120. Thereafter, the solenoid valve 130 is switched and the suction pressure is supplied to the suction region 124. As a result, the suction region 124 sucks and holds the leading end of the packaging web W1.

Thereafter, when the movable roller holder 118 is also rotated to the operating position, the pinch roller 122 of the movable roller holder 118 is moved to the delivery roller 104 via the packaging web W1, as shown in FIG. The wrapping web W1 is sandwiched between the feed roller 104 and the pinch roller 122 by rolling. Note that the one-dot chain line in FIG. 12 indicates the packaging web W when the rod manufacturing machine is in operation, that is, the web path.

[0097] At this time, the upper end surface 118a of the movable roller holder 118 is positioned immediately below the web guide 144, and the leading end of the packaging web W1 is near the lower end of the guide channel 154, that is, the corresponding guide groove 148 of the web guide 144. Positioned on.

[0098] In addition, the guide cover 152 has already been pivoted to the operating position, and the guide groove 152 is formed in the guide groove 148.

[0099] After the preparation work of the packaging web W1 is completed in this way, the supply of the element stream, that is, the composite element column C toward the forming path 38 is started, and at the same time,

E

The running of tape 40 is also started.

[0100] After that, with the composite element column C passing the guide roller 44, the solenoid valve 130

E

When the switching operation is performed and the holding of the front end portion of the packaging web W1 by the sac- tion is released, the solenoid valve 138 (Fig. 6) is switched and the compressed air is applied from the air ejection hole 132 of the movable roller holder 118 It is ejected toward the guide groove 148, that is, the lower end of the tunnel. Simultaneously with the switching operation of the solenoid valves 130 and 138, the electric motor 110 (see FIG. 7) is driven, and the feed roller 104 is also rotated at this time.

[0101] The rotation of the delivery roller 104 causes the force between the delivery roller 104 and each pinch roller 122 to also feed the packaging web W1, so that the leading end of the packaging web W1 corresponds to the corresponding guide groove 148, that is, the tunnel. Head for. At this time, the compressed air ejected from the air ejection holes 132 blows up the leading end of the packaging web W1 and reliably guides it into the guide groove 148. Therefore, the leading end of the packaging web W1 reaches the guide roller 44 through the guide groove 148, that is, the guide passage 154, and is sandwiched between the guide roller 44 and the corresponding composite element column C. This results in packaging

E

The leading edge of the web W1 is dragged to the composite element column C and

E E

In addition, the vehicle enters the introduction passage 164 described above.

[0102] After that, at the timing when the leading end of the packaging web W1 reaches the bottom guide 162, the above-described air cylinder 192 (see FIG. 11) is expanded, whereby the bottom guide 162 is moved upward by the wedge member 182. Slightly displaced. Therefore, the packaging web W1 and the composite element column C

E

The adhesive strength between the two increases, and the packaging web W1 is in the introduction passage 164 together with the composite element column C.

E

Can be surely passed, and enters the ganic tape 40.

[0103] As a result, the wrapping web W1 runs along with the composite element column C with the guillata tape 40.

E

Passes through the lapping unit 36 along the forming track 38 and wraps the composite element column C.

E

Look into.

As is clear from the above description, the guide passage 154 including the guide groove 148 and the introduction passage 164 form an introduction line for guiding the packaging web W 1 onto the forming passage 38.

[0105] After the wrapping web W1 has completely passed through the wrapping device 36, the gamut tape 40 is run, the composite element column C is fed, the wrapping web W1 is fed by the feed roller 104, and the air is blown.

E

The ejection of compressed air from the outlet 13 is stopped.

[0106] Thereafter, the air guide 192 is contracted in the bottom guide 162, and the bottom guide 162 returns to the original position. Further, the movable roller holder 118 and the guide cover 152 are returned to the preparation position and the rest position, respectively.

[0107] When the movable roller holder 118 is returned to the preparatory position, the packaging web W1 is separated from both the feed roller 104 and the pinch roller 122, and the web path when the rod making machine is in operation is removed. Located on the road.

[0108] During the above-described set-up operation, the packaging web Wl that has passed through the wrapping device 36, that is, the composite element rod ER is moved from the wrapping device 36 by the action of a deflector (not shown) that does not face the cutting device 46. It is discharged into a collection container (not shown).

[0109] After that, when the rod manufacturing machine is started, the rod manufacturing machine shifts to the constant speed operation, and the quality of the composite element rod ER is stabilized, the deflector cuts the composite element rod ER, Allow delivery of composite element rod ER from lapping device 36 to cutting device 46.

[0110] The present invention is not limited to the above-described embodiment. For example, the leading end of the packaging web may be held by a mechanical chuck, not by suction, and the feed roller 104 may be a movable roller. It may be attached to the holder 118 and the pinch roller 122 may be attached to the roller holder 100. In order to increase the adhesion between the composite element column C and the packaging web,

E

Roller 44 itself can be displaced up and down!

[0111] The setup device of the present invention is similar to a single track type rod manufacturing machine having only one forming path and a manufacturing machine for manufacturing a plain filter rod in which a tow of a fiber material is wrapped in a packaging web. Can be applied.

Furthermore, the setup device of the present invention can also be applied to a cigarette manufacturing machine.
