United States Patent 3,212,507 APPARATUS FOR PRODUCING MOUTHPIECE CIGARETTES Bernhard Schubert, Hamburg-Lohbrugge, Germany, assignor to Hauni-Werke Korber & C0. K.G., Hamburg- Bergedorf, Germany Filed Mar. 13, 1962, Ser. No. 179,431 Claims priority, application Germany, Mar. 16, 1961, H 42,037; Great Britain, May 23, 1961, 18,558/61 6 Claims. (Cl. 13121) The invention relates to apparatus for producing groups of axially aligned rod-shaped elements such as filter cigarettes and, in the event of a faulty cigarette feed, is concerned with means for stopping the feed of attachments as well as the feed of an advancing wrapper strip, which is gummed and partedinto sections. These sections are wrapped around groups consisting of cigarettes andmouthpieces and each groupconsisting for example of two cigarettes and an interposed mouthpiece of twice the final length.

The attachments referred to comprise all attachments or inserts for cigarettes, cigarillos, cigars and the like, and such attachments include composite filters, as well as rods or rod sections, and they may include mouthpieces consisting ofhollow tubes or mouthpiece portions partly or wholly filled with filter material or filter material without a wrapping, for example a plug of cotton wool. All these mouthpiece portions will hereinafter be referred to for convenience as plugs.

The feed of the strip is interrupted if disturbances oc- In this way the feed of a gummed strip section, which has not been wrapped around a group, is not carried onward into the machine with the danger of the machine parts being smeared with the adhesive which might involve stopping of the machine and loss of time for cleaning.

The inventionrelates to a preferred and simplified construction of and includes a clutch device for interrupting the feed of the plugs. The invention also includes a stationary braking surface ahead of the feed rollers as seen in the feed direction. According to a further feature of the invention the pressing of the strip against the breaking surface is effected by means of an electromagnet, to the movable armature of which is operatively connected or secured a braking surface.

FIG. 7 is a diagrammatic end view of a complete filter Patented Oct. 19, 1965 "ice cigarette machine which is constructed in accordance with my invention.

The part of the filter cigarette machine shown in FIG. 1 consists essentially of a feed duct or magazine duct 1 for filter rods 2, for example of three times a double plug length. Beneath the magazine duct 1 through which are fed the filterrods 2, there is provided a magazine takeoff drum 4 provided with grooves 3. Two circular cutters 5 are provided in the region of the grooves 3 of the take-off drum 4 for cutting the filter rods 2 into double length plugs 16. Three collating wheels 6a, 6b, 60, provided with grooves 7a, 7b, 7c co-operate with the takeoff drum 4 and are arranged so that three double length plugs 16 cut from each filter rod 2 are moved or displaced relative to one another before transfer to a grooved drum 8 arranged beneath the wheels 6a, 6b, so that the double length plugs 16 can be re-aligned to form an aligned row ahead of the drum 8. Concentric guide surfaces 17 are provided in relation to grooves 9 of the drum 8, which surfaces serve to retain the double length plugs 16 in position on the drum 8. Below the drum 8 there is provided a rotary conveyor here shown as a grooved wheel 10 having grooves '11, the grooved zone of which is intersected by an intermediate conveyor 12 with grooves 13 which in turn co-operates with a cigarette magazine drum 14 and has a groove pitch corresponding to grooves 15 of said drum 14.

Ahead of the intermediate conveyor 12, as viewed in the feeding direction and on the periphery of the cigarette magazine drum 14, there is provided a sensing means here shown as a feeler 22 pivotally movable in an adjustable holder 23, of which an operating pin 31 of a switch 24 co-operates with the feeler 22. The switch 24 is connected into an operating circuit 25 of a relay 62 which controls the circuit 27 ofa first arresting device including a clutch having a control electromagnet 28. The relay 26 also controls the circuit 68 of a second arresting device including a brake having an electromagnet (FIG. 6). One end of a control lever 29 is operated by the electromagnet 28, while the other end thereof (FIG. 2) operates a control shaft 30.

The drive of the filter cutting and feed device is effected from a main drive shaft of the machine, not shown, through a driving gear wheel 21 in such a manner that the grooved drum 8, grooved wheel 10, the collating wheels 6a, 6b, 6c, the magazines take-off drum 4 as well as the intermediate conveyor 12 are all driven from a hollow driven shaft 20, shown best in FIG. 2. The whole device is adapted to be brought into operation by means of a clutch device to be described more fully hereinafter, while the cigarette magazine drum 14 and the other parts of the filter cigarette machine are driven separatelyfrom the main drive.

The construction of the clutch will now be described in conjunction with FIGS. 2, 3 and 4. The driving gear wheel 21 already referred to is rotatable on a spindle 32 and is mounted between stationary walls 18 and 19. A flange 33 of the gear wheel 21 has two lugs 34 which engage with an axially slidable drive clutch disc 35 which is spaced by compression springs 36 from the flange 33. The springs 36 are guided in bores 46 in flange 33 and in disc 35. The hollow driven shaft 20 carries the grooved wheel 10 (see FIGS. 1 and 2) with grooves 11 and is rotatable on and suitably locked to the spindle 32 by means of a ring 80, a bearing 81 and a screw 82. A gear wheel 38 is fastened by means of screws 38' to a tapered portion 37 of the driven shaft 20 and includes dogs 39, as shown in FIG. 4, which engage between dogs 40 of the drive clutch disc 35 (FIG. 3). A thrust bearing 41 engages flange 45 of the drive clutch disc 35 (FIG. 3). A transmission bar 42 for axially displacing the thrust bearing 41 is fastened to the other end 43 of the 3 control shaft 30. The number of dogs 40 in the drive clutch disc 35 corresponds to the number of grooves 11 in the grooved wheel 10. The drive clutch disc 35 has recesses 44 inwhich engage the lugs 34 of the flange 33 of the driving gear wheel 21.

FIG. 4 shows an elevational view of the gear wheel 38 the dogs 39 of which include inclined portions 47 in order that they can slip easily into the gaps between the dogs 40 of the drive clutch disc 35 (FIG. 3). The gear wheel 38 drives the intermediate conveyor 12 as already stated through an intermediate gear wheel 48, as shown in FIG. 2.

FIG. shows a base plate 50 with a vertically mounted support 51. A bobbin holder 52 for a bobbin or reel 53 of wrapping material is fastened to the support 51 on which the stationary wall 19 is mounted. The bobbin 53 is rotatably mounted on a shaft 55 by means of a clamp disc 54. A rotatable guide roll 57 on a holder 56 is provided on the base plate 50 beneath the bobbin holder 52. The guide roll 57 precedes a braking device 60 in the direction of movement of a strip 58 of the wrapping material as indicated by an arrow 59. This braking device 60 is mounted on the base plate 50 by means of an angle support 61. It comprises a brake block 62 (-FIG. 6) displaceably .mounted on the angle bracket 61 and provided with a braking surface 63 consisting of rubber or the like -for engaging the face of the strip remote from the brake block 62. Adjustment is permitted by a slot 64 through which pass the fastening screws for the brake block 62.

The breaking electromagnet 65 is provided beneath the brake block 62 and an operating rod 66 associated with the magnet armature is directed towards brake block 62. The electromagnet 65 may be adjusted and fixed after adjustment by means of an elongated slot 67 in the angle support 61 in a manner similar to the brake block 62. The supply of current is effected through circuit 68 connected to the control circuit 27. Between the operating rod 66 and the brake block 62 there is provided an arcuate brake jaw 69 with a brake lining 70 possessing a friction surface for example-of rubber. This brake jaw 69 is mounted by a hinge 71 to an angle support 72 mounted on the electromagnet 65.

The braking device 60 is followed by a further guide roller 73 (FIG. 5) as well as a pair of feed rollers comprising a driving roller 74 and a presser roller 75 with a yieldable surface. A further guide roller 76 is arranged between a suction drum not shown, and the pair of feed rollers 74 and 75. If desired by the interposition of additional guide rollers, the strip 58 may be cut to required lengths by means of a cutting device, for example a rotating cutter drum. The construction and arrangement of a suitable form of cutter drum and associated parts is commonly known and constitutes no part of the invention.

In order to stop the driven part of the clutch immediately after disengaging the clutch a braking device generally designated by reference numeral 90 is fastened to the wall 19. This braking device consists of a holder 91 in which is pivotally mounted a fork-like lever 92, one end of which bears a roller 93 which engages the flat part of the outer face of the intermediate member or drive clutch disc 35, and the other end of which is provided with a braking shoe 94 arranged to engage the periphery of the flange of the tapered portion 37 when the clutch is disengaged. A tension spring 95, one end of which is attached to the wall 19 and the other end of which is attached to the fork-like lever 92, pulls roller 93 continuously against the flat part of the outer face of the intermediate member or drive clutch disc 35 whereby in the disengaged position of the clutch the braking shoe 94 engages the flange of the tapered portion 37 thereby holding the driven and now disengaged clutch part substantially instantaneously.

The method of operation is as follows: When cigarettes C arrive under switch 24 and lift the feeler 22 thereby operating switch 24, the filter cutting and feed device is brought into operation. This position of feeler 22 is maintained during the normal running of the machine. If now for any reason the cigarette feed is interrupted the feeler 22 moves towards the periphery of drum 14 thereby operating the switch 24. This may cause the circuit 25 of the relay-26 to be opened or closed depending on whether the electromagnet 28 in the circuit 27 needs to be de-energized or energized in order to operate the drive clutch disc 35, either method being possible. In the present case switch 24 closes circuit 25 which operates relay 26 thereby closing the circuit 27 of the operating electromagnet 28 which actuates the control lever 29 (FIG. '2). The resulting rocking movement causes the other arm of the lever 29 to move the control shaft 30 in the direction of the arrow 78. Thereby the transmission bar 42 is pressed against the thrust bearing 41 which engages drive clutch disc 35 so that the dogs 40 of the drive clutch disc 35 are separated from the dogs 39 of the gear wheel 38. The drive to the filter cutting and feed device is thereby interrupted causing stoppage of the rotating parts of the filter cutting and feed device. As soon as cigarettes C are again fed by the cigarette magazine drum 14 so as to operate feeler 22 the electromagnet 28 is de-energized and the springs 36 press the drive clutch disc 35 towards the gear wheel 38 whereby the dogs 39 of the gear wheel 38 assisted by the inclined portions 47, slip quickly and easily between the dogs 40 of the drive clutch disc 35.

When the feeler 22 described with reference to FIG. 1 operates the electromagnet 28 due to empty grooves 15 on the magazine drum 14, simultaneously the electromagnet 65 (FIG. 6) controlled by circuit 68 is energized Which pushes the operating rod 66 outwardly and presses the brake jaw 69 against the paper strip 58 which is thereby held between the brake jaw 69 and the braking surface 63 of the brake block 62. Because of this action the paper strip 58 slips on and cannot be withdrawn by the driving roller 74. Damage to the strip 58 will not occur because disturbances or interruptions in the feed during normal running conditions are only momentary.- For long-term disturbances the whole machine would be stopped. When the cigarette magazine drum 14 again feeds the cigarettes C the feeler 22 is lifted and the relay 26 and the electromagnets 28, 65 are de-energized. The armature with the operating rod 66 and the brake jaw 69 are then retracted in the present case by their own weight. The strip 58 is no longer retarded and can be again fed forward by the feed rollers 74, 75 towards the previously mentioned cutting means to meet correctly assembled cigarette-mouthpiece groups.

FIG. 7 illustrates a complete filter cigarette machine which embodies the structure of FIG. 1 but the parts 1, 4, 5, 6a, 6b, 8, 10, 12 and 14 shown in FIG. 7 are mirror symmetrical with reference to the corresponding parts shown in FIG. 1. Thus, the cigarette magazine drum 14 of FIG. 7 rotates in a counterclockwise direction and the magazine take-off drum 4 of FIG. 7 also rotates in a counterclockwise direction. Parts of the coupling device shown in FIG. 2 and the feeler 22 of FIG. 1 were omitted in FIG. 7 for the sake of clarity. The braking device 60 is shown in the lower right-hand portion of FIG. 7.

The duct 1 forms part of a magazine which contains a supply of filter rods 2, and the duct 1 feeds such filter rods into the grooves of the drum 4 which coop erates with the cutters 5 and feeds the plugs 16 to thecollating wheels 6a, 6b, 6c. The wheels 6a6b feed the;

plugs 16 into the grooves of the drum 8 which forms a. single file of such plugs and delivers them to the wheel 10. The wheel 10 transfers the plugs into consecutive grooves of the conveyor 12 which delivers such plugs into the spaces between pairs of coaxial cigarettes C accommodated in the grooves of the drum 14. The drum 14 receives such cigarettes from an intermediate drum 101. The assemblies consisting of pairs of coaxial cigarettes C and a plug 16 therebetween are transferred into the grooves of an intermediate drum 102 which cooperates with a suction drum 105, the latter serving to apply an adhesive-coated rectangular wrapper 104 to each of the assemblies in the grooves of the drum 102. The drum 105 is adjacent to a paster 103 serving to coat with adhesive one side of the wrapper tape or strip 58 stored on the reel 53. The strip 58 passes along the guide roll 57, through the braking device 60, around the guide roller 73, between the feed rolls 74, 75, on to the paster 103, and finally to the suction drum 105. The drum 105 cooperates with a rotary knife 111 whose radially extending blades sever the leading end portion of the strip on the drum 105 to form the wrappers 104. The paster 103 comprises a tank 112, a transfer roller 113 which dips into the tank 112, and a roller-shaped applicator 114 which receives a film of adhesive on contact with the periphery of the roller 113. On its way from the feed rolls 74, 75 to the applicator 114, the strip 58 travels around a series of deflecting rollers 108.

The intermediate drum 102 advances the assemblies of cigarettes C and plugs 16 (each of which is provided with a wrapper 104) into consecutive pockets of a wrapping drum 115 which convolutes the wrappers 104 around the respective assemblies in a manner well known in the art (see, for example, my US. Patent No. 2,714,384 or my copending application Serial No. 162,431 filed jointly with Guenter Wahle on December 27, 1961 and now abandoned); and the thus obtained filter cigarettes of double unit length are thereupon delivered into consecutive pockets of a transfer drum 116 which deposits such filter cigarettes on the upper stringer of a take-off belt 117.

The drive mechanism for the machine of FIG. 7 comprises a driver pinion 120 whichrneshes with a gear 121 coaxia'lly fixed to the wrapping drum 115. The gear 121 meshes with a gear 122 which drives the transfer drum 116 and with a gear 123 which drives the intermediate drum 102. The gear 123 meshes with a gear 124 which drives the drum 14 and which meshes with a pinion 125 for the intermediate drum 101. The gear 123 also meshes with an intermediate pinion 126 which meshes with an intermediate gear 127, and the gear 127 meshes with a gear 128. The shaft of the gear 128 is rigidly secured to the gear wheel 49 (see also FIG. 2) which meshes with the driving gear wheel 21. The gear wheel 21 drives the gear wheel 38 in a manner as shown in FIG. 2, and the gear wheel 38 drives a gear 129 for the drum 8. Also, the gear wheel 38 meshes with the gear wheel 48 which meshes with a pinion 130 on the shaft of the conveyor 12.

The gear 129 meshes with a pinion 131 which drives a gear 132 for the drum 4. The pinion 131 also meshes with pinions 133, 134 which drive the collating wheels 6a, 6b, 6c. The wheels 6a6c are driven by three separate gears which are mounted on the shaft of the pinion 134.

The gear 124 for the drum meshes with a gear 135 which is coaxially secured to a pinion 136. This pinion 136 meshes with a pinion 137 which drives an intermediate pinion 138 meshing with a pinion 139 on the shaft of the feed roll 74. The pinion 137 also meshes with a gear 140 on the shaft of the knife 111, and the gear 140 drives the gear 141 for the drum 105. The gear 141 meshes with a pinion 142 which drives the gear 143 of the transfer roller 113, and the gear 143 drives the pinion 144 of the applicator 114. The driving connection between the pinion 139 and the feed roll 74 normally comprises a suitable clutch, not shown in FIG. 7.

It is obvious that parts of the present invention may be used independently either as a device to cut off the feed of filters or plugs or as a device to cut-off the feed of a wrapper strip in the absence of cigarettes.
