Abstract

THE INVENTION RELATES TO A PROCESS AND A DEVICE FOR CONTINUOUSLY FEEDING TAPE OF PAPER TO A TOBACCO PROCESSING MACHINE. FULL COILS ARE STORED IN A MAGAZINE 24 FROM WHICH THEY ARE TAKEN ONE AFTER THE OTHER BY A TAPPING DEVICE 30 WHICH TAKES THEM TO A COIL CHANGER 18. THE LATTER REMOVES AN EMPTY COIL FROM A SPOOL CHUCK 20 , 22 AND REPLACE IT WITH A SOLID COIL. THE TWO MANDRELS 20, 22 OPERATE IN TURNS SO THAT THE PAPER FEED IS CONTINUOUS. THE INVENTION APPLIES IN PARTICULAR TO THE MANUFACTURE OF CIGARETTES AND FILTERS.

Description

The present invention relates to feeding devices for

  machines of the tobacco processing industry, and more particularly relates to a method of continuously feeding a paper web wound on individual bobbins, as well as an automatic feeding device with a reel changing device.

  intended for a largely automated machine.

  Despite the very high degree of automation,

  especially in the manufacture of cigarettes, it is still necessary to manually change the paper rolls, that is to say it is necessary to remove an empty bobbin or a bobbin mandrel while a second full reel

unfolds.

  Because of the high throughput in production, these

  Frequent interventions are long and laborious. In addition,

  the unrolled coil whose end of the strip was

  linked to the beginning of the band of the new

  should be removed and a permuta-

  between the empty reel holder which has a mandrel

  freely rotating and a full spool holder, before

  spin a new roll of paper over the mandrel.

  Some simplification of the work is provided by semi-automatic coil changing devices in which the bobbin chucks are mounted

  on radially oscillating arms, diametrically oppo-

  or on an oscillating disc and which allow a change

  automatically in both positions between a full reel and an unwound reel. Even with these semi-automatic reel changers, which are known for example for bringing cigarette paper to wrap

  tobacco stalks in a manufacturing machine of

  garettes, paper load filters cigarettes in a machine to fix the filter tips, or paper

  wrapping in a wire-making machine

  very, replacing an empty reel with a reel

  full must still be done by hand.

  In addition, the rotational movement for the change operation requires relatively much room, even if the change is made only when a coil

  implementation beforehand has already taken place in part.

  This is particularly problematic with

  machines in which the space available for

  paper mills is limited, for example by projecting machine parts, in which case the money changers

  semiautomatic devices already known can not be used.

  For this reason, a cigarette machine is also

  known in which the semi-automatic changer is

  on one side of the machine. This presents especially the

  a long drive for paper to the side

  front of the machine, on which this paper can be lightly

damaged.

  The object of the invention is therefore essentially to

  to provide a method and apparatus for improving the continuous delivery of a paper web wound on

  single-coil machines comprising a device

  tif of coil change, and allowing by a wide automation of operations, easy, fast work

and reliable.

  For this purpose, the invention therefore relates to a

  continuous feeding with a strip of paper

  rolled on reels, a reel changing device of a tobacco processing industry machine;

  essentially consists in having a certain

  number of full coils next to the coil changing device, parallel to the work plane of the coil changing device, next to each other in a coaxial row, to move these coils one step forward after the others in a plane in front of the working plane of the coil changing device, and transversely moving the coils in this plane, with respect to the reserve row, in front of the empty mandrels of the change device on which they are threaded , before in a next operation the working positions are switched to replace reels unwound by full coils, to remove unwound reels from their mandrel and to place them in their recovery tank while they move in the plane of the movement in front of the worktop, to the row of spare coils between the changeover device and the spare row before the next coil is taken from

this row.

  The process according to the invention is therefore characterized

  by a series of movements in which coils

  placed parallel to their final vertical working position are taken from a magazine which contains a row of full coils placed one behind the other and are driven towards the change device.

  on the same path as that by which a reel

  It is removed and moved back to be removed before the next coil is taken. The invention thus allows an accelerated progress of operations compared to the state of the art, in which the full coils are generally stacked on a table

  near the machine, on which they are

  after the change of position of the mandrels and the

removing the empty reel.

  The invention further relates to a device that allows for greater automation of operations, in order to further reduce the workload by

  use, namely the supervision of the machine.

  According to one characteristic of the invention, the change

  position of the coils is not performed by a

  circular motion as in semi-

  known automatic coil change but along

  of a closed curve along which a coil of

  actually unrolled is slightly raised and driven

  in the paper feed direction while the paper is

  vacuum is lowered under the unrolling spool, in the opposite direction of the paper feed direction, before

  to be removed and replaced by a new reel.

  This permutation motion allows a particular arrangement

  It is compact and flat with a small depth on a relatively small machine surface which could not be suitable for changing devices.

reel so far.

  Other features of advantages of the invention

  will appear in the following description and

  in the accompanying drawings given solely as examples

  in no way limiting and in which: Figure 1 is a perspective view of a machine assembly for the manufacture of filter tips with

  a machine equipped with buckets according to the invention func-

  Figure 2 and in partial section showing the guiding curve

  of the mobile support of a free chuck for receiving

  coil of the coil changing device according to

  vention. Figure 1 therefore shows a device 10 according to the invention, associated with a set of a machine 12 to manufacture cigarettes and a machine 14 to assemble the filter tips. The device 10 serves to automatically feed the cigarette machine 12 with cigarette paper to wrap in this machine stems

of tobacco already formed.

  There is sufficient room for the feed device according to the invention, which is particularly compact, under a connecting channel 16 and between

  adjacent front edges of the machines 12 and 14 arranged

  specifically relative to each other. It is therefore possible to retrofit a known machine set,

  with a device according to the invention.

  The automatic feeding device 10, represented

  also in perspective in Figure 2, includes

  essentially a device 18 for automatic change

  of coil according to the invention with two mandrels with

  20 and 22, a reel magazine 24 for holding a number of paper reels 26 parallel to the mandrels 20 and 22, arranged next to each other and movable forwardly, and a gripping device 30 and automatic elimination, movable in one direction and the other in a guide 28, perpendicular to the axis of the coils, between the coil changer 18 and the coil magazine 24. In this case, the paper reels 26

  consist of narrow paper strips, wound

  typically on plastic cores, or

25.

  The next element 32 of the machine 12, in the di-

  paper advance, is already known and comprises, in addition to a control device and a printer to print the brand of cigarettes, a combination of driven rollers for pulling the paper tape

  the coil thus driven, as well as a device for

  appearance of the ends of the ban-

  reels 26 installed successively, and of which

  Also included is a locker 34 for receiving

  visibly a reserve of tapes. This reserve of paper tape, prepared before connecting the successive end sections of the different coils 26, allows the stopping of

  training of the band during assembly of the ex-

  tremities and a start without pressure of the new band.

2 472918

  In an earlier device for changing

  of a known machine 12, the change operation in itself must be carried out by hand, namely with

  using a straight rail on which new

  are placed at the back and are advanced after

  the removal of empty reels. This is because of a

  in-depth position of the changeover device

  bine, under a protruding part of the machine, limiting the place for the change of position of the coils, so that an automatic operation of change seems impossible.

  The coil changing device 18 according to the invention

  This solution solves this problem by means of a closed control curve, preferably in the form of an equilateral triangle, directed downwards, with rounded corners. and also serving as a guide rail, as shown in Figure 5, for support carriages 42, 44 on which the mandrels can freely rotate

of coils 20 and 22.

  In this example, training for

  reel change rations is provided by an engine

  46 connected to the control device and a chain 48

  trailing another chain 50 which follows at a distance

  stant the guide rail 40, on all sides, in step

  on a driven gearwheel 52 and two

  54, 56 freely rotating, and on which are

  stained the support trolleys 42 and 44 of the bobbin mandrels

  20 and 22, at equal distances. The coaching chain

  48 passes behind, that is to say under the guide rail 40 and on a drive gear, placed

  behind the gear 52 and turning with it.

  According to the invention, the magazine 24 with coils of the dis-

  positive feed 10 preferably consists of a continuous conveyor, controlled step by step, with a support V, preferably 900, constituted for example by

  two conveyor belts or slats, 60, 62.

  The supports 64, 66 of the conveyor 60, 62 shown

  can be set relative to one another, for example

  by an overall motion perpendicular to the convolution

  Yeur, on a common support plate 68. This allows easy adaptation to the different diameters of the coils and a slight adjustment of the tolerances of the values of

  these diameters. The symmetrical arrangement with an inclination

  450 of the conveyor support surfaces 62, 64

  Moreover, they offer the advantage of allowing a symmetrical

  and without rotation of the lateral and vertical

  spacing of the reel axes, regardless of their di-

  metre. In the present embodiment, the V-support 52, 64 of the conveyor 24 is inclined forward by an angle alpha. This angle can be between 30 and 80 and allows, together with a stop and hold device 70, a positioning of the reels 26 in the magazine 24 without any additional adjustable support at the rear end of the magazine. This arrangement offers the particular advantage that the magazine 24 can be freely loaded at any time from the back with new

  coils, and without any gene by stops or others.

  The stop and hold device 70 consists of a box 72 in the form of a column, fixed for example on the base plate 68 of the magazine 24. Two oscillating arms

  74 and 76, supported in 78 and 80, possibly on the

  common law, are located in the upper part of the

  casing, one behind the other in the direction of the

  parallel to the inclined plane. The arms 74 and 76

  inwards, beyond the points of articula-

  78 and 80, extensions 82 and 84 in the form of

  to which joints of the devices for controlling the tilting movement of the arms are coupled. These control devices consist for example of pneumatic cylinders 86, 88 with double effect which are

  operated by electrically controlled valves of a dis-

positive control of the machine.

  Guide 28 of the device 30 for making and

  is a short distance and parallel

  in front of the machine 12 and the: store. As shown in Figure 2, it consists of two guide rods 90 and 91 disposed one above the other between two blocks 93 and 94 of abutment and support, fixed on a support plate 92. The latter can be connected to the plate

support 68 of the magazine 24.

  For example, a cable drive or

  by chain is provided for the controlled movement of the

  The drive is provided by an electric servomotor 95 fixed to the mounting block 93 on the left, a driving pulley 96 driven by this motor and another pulley 97 freely rotating on the mounting block 94 of FIG. right, who receive a cable

  or a chain 98 whose free ends are hooked

  on each side of the device, for example

  rear fixing points 99a and 99b.

  Since, as shown in Figure 2, the coils tilt forward in correspondence with

  the inclination of the support cn V 60, 62 of the magazine 24, the dis-

  the positive end 30 driven in front of the sampling end of the magazine 24 must tilt a corresponding angle in the coaxial direction to receive a full spool, while during the movement for the change of the spool, it must be arranged so that the engaging and eliminating member in the other end position of the device 30 is coaxial with a coil mandrel

  20 which turns on a horizontal axis.

  A simple way to make this movement

  the tilt and shift of the device 30

  for example to have guide rods 90 and

  91 so that they are in horizontal planes

  parallel, but that they divide in

2 4 72 9 18

  perpendicular to these, in the direction of

  placement of the device 30, in correspondence with the angle of inclination of the support 62, 64 of the magazine. As shown in Figure 2, the upper guide rod 90 is arranged for example parallel to the working plane of the coil changing device 18. The fixing points of the two guide rods 90 and 91 in the mounting block 94 on the right are vertically one above the other.

  the other while the point of attachment of the

  bottom bracket 9l in the mounting block 93 on the left is

  is closer to the outlet end of the store.

  24 than the point of attachment of the upper rod

  90. At the left end of Guide 28, the fixing points

  90 and 91 guide rods make an angle alpha

  corresponding to the angle of inclination of the conveyor.

  Figures 3 and 4 show the main elements

  in a simple embodiment of a device 30

  according to the invention of taking and eliminating.

  A support trolley 100, mobile on a rod guide

  as in Figure 2, therefore has a guide hole.

  102 which may for example contain a bearing pad

  Another guiding device consists of two

  rollers 106 and 108 disposed on the underside of the chain.

  riot support, and which cooperate with the guide rod 91,

  see Figure 2. The lateral guidance open down, as-

  secured by the rollers allows a strengthening of the lower guide rod 91 which may be constituted for example by the upper edge of an edge of the support plate 92 folded vertically. As shown in Figure 4, it is possible to provide on the bottom of the trolley

  support, an electric motor 110 controlled for training

  directly from the roller 108 cooperating with the rod of guiding

  91 instead of driving the device 30 by cable or chain, as has already been explained. A

247 2918

  meshing between the roller 108 and the guide rod 91

  guarantees extremely high training accuracy.

  On the support carriage 100 there is a support plate

  port 112 which can move in one direction and the other by means of an adjusting device 114, 116 coupled between

  the cart and the plate. The plate 112 supports a device

  120 is attached to it by means of a base piece 118, and which moves in one direction and the other

with her, the same movement.

  A simple embodiment of the operating device consists of a two-piece clamping chuck, of which

  the lower part 122 is fixed on the base part 118.

  The upper piece 124 of the setting device 120 is ac-

  coupled by an adjusting device 126, 128 with double

  fet with the base piece 118 of the lower part 122

  and can move relative to it. A segment 130 mo-

  bile with the upper part of the gripping device 120 allows, with a vertical guide rail 132, a guide

  in an element 134 fixed on the lower part 118, 122.

  On the support plate 112 are also arranged perpendicularly to the direction of their movement,

  movable support members 136 and 138 which can be moved

  in opposite directions by adjusters 138, 140 or 142, 144. Adjusters

  146, 150 disposed on the supporting members 136, 138 supporting

  symmetrically, on both sides of the service

  rabies 120, organs 152 and 154 for setting and eliminating

  whose operation will be explained later.

  Finally, Figure 5 shows the essential elements of a possible embodiment of a door - ') obine suitable for a coil changing device 18 according to the invention. The spool mandrel 22 shown freely rotates by means of a bearing 156 on an axis 158 supported by the support carriage 44. The mandrel 22 comprises a flange D5 160 projecting on the rear edge, - serving

  stop for a threaded spool, and a device for

2 4 7 29 18

  latching to keep the coil threaded, and which

  is released momentarily at the start and removal

  a coil, when approaching the gripping device 120.

  The interlocking device consists for example of three or four interlocking elements 151 distributed uniformly around the circumference of the mandrel, which can

  pivot on axes perpendicular to the axis 158 of the man-

  drin, in housing 162 parallel to the axis, and which comprise a nose-shaped engagement portion which, in the engagement position, protrude through an opening

  in the outer surface of the mandrel 22. Each element -

  latch 161 is normally maintained in the posi-

  an engagement spring represented by a return spring 163 and can be tilted into the disengaged position under the effect of a mechanism 164, 166 freely accessible by

  the front, and located in the area of the front of the man-

  drin. The spring 163 can be for example a spring of

  compression arranged between the inner end of the box

  162 and an eccentric attachment point with respect to the pivot axis, on the opposite side of the element

of lcleg1nchem.nt 161.

  The actuating mechanism consists for example in

  a rod 164 exiting through the open end of the housing.

  An annular disk 166 is coupled with the ends

  free protruding actuating rods 164 of the different

  interlocking elements 161. The action ring

  The common pattern 166 imparts identical movement to all interlocking members 161 and furthermore avoids any danger to the operating and monitoring personnel caused by

  by protruding parts on the mandrels 20, 22 in the form of

  on the front of the machine. Particular guidance

  - The device 30 of catch and elimination is

  dragged along the guide 28, see Figure 2, to the left,

  in front of the sampling end of the magazine 24 with coils.

  The two-piece gripping device 120 passes into its clamping position by the control device 114, 116 with the support plate 112 fed into the central part of the spool 26, and clamped by the control device 126, 128. At the same time time, the stop arm 74 of the device tilts upwardly so that the first coil

  can be taken from the store during the journey

turn of the gripping device 120.

  The device 30 then moves on the guide 28 to the right, in front of the empty spool mandrel 20, in

  the rear position shown on the left in Figure 2.

  tion. At this moment, the engagement nosings 161 swing

  in their position of release under the

  tif of the grip that meets the ring 166, as described above. The lateral gripping members 152, 154 are advanced by the control devices 146 to 150, and move the take-up device coil 120 over the mandrel 20 as soon as the engagement device releases the upper portion 124 of the tight coil. The support plate 112 is then brought back with the organs

  taking and disposal. The annular disc 166 is

  bere so that the snap nosings 161 pass into the engagement position shown in FIG. 5,

  and the coil is firmly held.

  As soon as the coil changing device has partially brought the coil 25, 26 to the mandrel 20, the motor 46 which consists for example of a brake motor

  change ration of the two coil chucks 20 and 22.

  With an outer diameter of the 500 mm coil, the operation

  change is triggered for example by a dialogue

  approximately 400 mm, which is detected optically or by an existing brake and key lever anyway on the machine, in order to emit the control signal for

starting the engine 46.

  At the end of the reel change operation, an empty reel 25 on mandrel 22, unwound to

  what's left is a small piece of paper, and a

  25, 26 which is at this moment on the mandrel 20 have changed position of work as shown in Figure 2. The elements 152, 154 which, before the

  setting up a full reel are tight on the over-

  As used herein, the wound paper side, as the removal device, now behaves as an external clamping device which, by means of the control device 138, or 142, 144 approaches the empty coil core 25 from the outside and the greenhouse. At this moment, the devices

  element to release the coil core. By the subsequent return movement of the support plate 112, the empty coil core 25 is clamped between the clamps 152 and 154 and is withdrawn from the mandrel 22. The device then returns to the magazine on the guide 28. In this way, the empty reel is either abandoned or extended by the spacing of the clamps 152, 154 between the machine 12 and the reel magazine 24, in a tank 36 possibly placed there.

(see Figure 1).

  After the above described tap of the first full reel at the take-off end of the reel magazine 24, the row of reels 26 in the magazine advances the thickness of a reel. For this purpose, the arm 74 raised under the effect of a command signal

  of tracking to release the first reel removed

  comes in its position shown in Figure 2 to serve as a stop in the path of the coils, before the holding arm resting on the second coil and which to

  the release of the row of coils by the arm 24 em-

  fishing the tilting or sliding of the following reel

  is raised and the coil conveyor 60, 62

  moves forward of the thickness of a coil,

  than the stop 74. After this step in advance, the arm of

  now 76 is now pivoting behind the spool now on the stop 74 on the periphery of the next spool, thereby providing security against further slippage of the spools on the support, to unload the stop arm 74. In this starting position, the next spool is taken from the front end of the magazine, as described above, and

  is driven on the reel mandrel to the working position

  before and slipped on him; before the reel

  in the meantime be taken after another operation

  of change and that the next full reel is taken.

  The different functions of the feeding device

  according to the invention are triggered by means of an automatic control device, that is to say under the effect of transmitters of control signals, for example mechanical, electrical, magnetic that can already be part of the machine equipped according to the invention.
