Plant for the production of cigarette paper books

The invention relates to a system according to the preamble of claim 1.

Cigarette paper books of the type in question are known from DE-GM 1 695 678, 82 03 607 and 295 02 062. The production of these cigarette paper books is not easy because the packets consisting of the thin cigarette paper sheets, which are to be surrounded by the cardboard booklet cut-out, are delicate and not very stable.

The systems for producing cigarette paper books are complex and form machines of considerable size, although the cigarette paper books are relatively small and are probably the smallest cardboard packaging that is commonly used in the trade in any significant quantity. Many elements move in these machines during operation, which has so far led to

This meant that the capacity of such machines was limited and the noise generated during their operation was considerable.

The invention is based on the object of improving a plant for producing cigarette paper books.

This object is solved by the invention set out in claim 1.

The continuous, steady and constant speed of the blanks means that the tools involved also move evenly and continuously, i.e. jerky back and forth movements are avoided. Such movements are disadvantageous because they consume energy, promote wear, cause noise and, in particular, limit the working speed and availability of the system due to frequent damage. These disadvantageous phenomena are reduced by the uniformity of the movements of the components involved. Significant increases in production can be achieved by increasing the speed during operation and reducing downtimes. The uniformity of the movement applies to the main components of the system, i.e. the various tools and transport means as a whole, which, due to their higher mass, cause the problems mentioned when repeatedly stopping and re-accelerating. However, it cannot be ruled out that individual smaller components, e.g. the tools, also perform alternating movements in the invention. Such smaller components have only a minor influence on the smooth running and do not prevent the implementation of the inventive concept described above.

Specifically, the tufting station primarily responsible for the unfavorable phenomena in the cigarette packet according to the invention can

pierbuchel manufacturing plant can be designed in the manner set out in claim 2.

The flat, cuboid-shaped packets of cigarette paper sheets can be manufactured according to DE 42 01 256 C2 or EP 165 747 B1. The device for feeding the cardboard blanks can correspond to EP 627 374 B1. The device according to EP 265 870 B1 is advantageous for removing the blanks from the fed stack.

A suitable design of the device for erecting the side flaps is the subject of claim 3. It comprises cooperating complementary upper and lower tools which run one above the other at the same speed in a working section on supports designed as endlessly rotating flexible tension members, of which the upper tools in the working section engage with a stamp in a correspondingly designed recess of the respectively associated lower tool and in the process press recesses into the respective blanks for receiving a packet.

The design of the tool guide can be carried out in detail in the manner set out in claims 4 to 8.

The flexible supports of the upper tools and/or the lower tools are expediently designed as link chains (claim 9) which can rotate over deflection wheels (claim 10).

In detail, the upper tools can be designed in the manner set out in claim 11. The movement of the upper tools takes place by being carried along on the corresponding supports, the advance of the punch into the recess of the respective lower tool by displacement of the punches on their holders against the spring action. This displacement is brought about by the guide rails fixed to the machine.

An important embodiment is the subject of claim 12: the flexible carrier of the lower tools is considerably longer than that of the upper tools, and the respective lower tool transports the respective blank provided with the recess from the area of the upper tools into the area of filling with the respective packet and gluing.

According to claim 13, the device for feeding the packets can feed them in a continuous strand with the flat sides abutting one another and with the longer side of the plan horizontal. The packets are produced in a packet forming station belonging to the system but arranged outside the tuft forming station and are brought together to form the strand. Suitable devices for forming the packets are mentioned in connection with claim 2.

According to claim 14, the feed device can form a strand section leading from the packet forming station, which in the plan area of the packet forming station changes into an arc into a vertical end section, from the end of which the packets can be removed.

In the preferred embodiment according to claim 15, the strand section runs in the arch from top to bottom, so that the packets can be removed from below.

A feature of the preferred embodiment is the essentially horizontal or only slightly inclined course of the strand section leading from the packet formation station according to claim 16. Depending on the configuration of the overall system, however, other directions of the approach are also conceivable.

To guide the strand section in the area of the bundle forming station, a guide rail arrangement adapted in cross-section to the outline of the packets is expedient (claim 17).

·

·

An important individual feature according to claim 18 is that the guide rail arrangement has a height, at least in the area of the arch, that exceeds the width of the packets whose flat sides are adjacent to one another. "Height" refers to the extension in the direction of the short rectangular side of the packet outline. In this direction, there should therefore be a certain amount of play in the guide so that the packets can shift a little.

This is of particular importance in connection with the control according to claim 19, in which a flexible control strip rests under a force on the outside of the sheet running from top to bottom. The control strip, under which the packets in the sheet slide through in their strand, is operatively connected to a proximity sensor arrangement which controls the merging of the packets and the blanks.

If the string of fed packets stops or is no longer completely full, the proximity sensor arrangement can be used to interrupt the removal of packets from the end of the string in order to give the feeder an opportunity to refill. Otherwise, it could happen that too few packets are available and the booklet forming station produces one or two books without being filled.

In practice, the booklet forming station is usually a little faster than the packet forming station, which sometimes lags behind due to the inevitable disruptions in packet formation. The flexible strip with the proximity sensor arrangement therefore serves to ensure that the cigarette paper booklets are filled correctly.

According to claim 20, the force pressing the control strip onto the outside of the sheet is given by a weight, which represents the simplest realization of a constant pressing force.
30

The function of the arch through which the packet string is conveyed and whose guide rail arrangement leaves a certain amount of play in the direction of the short side of the packet outline is that

the packet string in the guide can shift slightly radially in relation to the sheet depending on the post-feed pressure. As the post-feed pressure increases, the packet string is pushed radially outwards and falls radially inwards as the feed pressure decreases. This shift is used for control purposes and is absorbed by the control strip.

The conversion of the displacement of the control strip into a preferably electrical signal is advantageously carried out in that the control strip comprises at its free end an element which projects radially outwards from the control strip with respect to the arc and which engages between two proximity sensors arranged one above the other at a distance, which together form the proximity sensor arrangement (claim 21).

Depending on the direction in which the packet string moves in the sheet and takes the control strip with it, the "element" approaches one proximity sensor at a time and the other at a time, which allows the control to be designed.

For example, according to claim 22, the transfer of the blanks to the lower tools can be interrupted by means of the signal from the proximity sensor arrangement. If the post-feed of the packet string is too low, which leads to a corresponding displacement of the same in the sheet, the transfer of blanks is completely or partially interrupted until the post-feed pressure increases again and the packet string passes the sheet in a middle position.

An example arrangement for interrupting the removal of the packets from the lower end of the line is the subject of claim 23. The removal of the packets from the end of the feed line only takes place when this line is sufficiently full. If this is not the case, which is determined by the flexible strip and the proximity sensor arrangement for fine filling, the removal of a packet is not carried out.

&bull; 4 ··

An important design of the control is the subject of claim 24. The essentially horizontal part of the guide rail arrangement located in front of the sheet - viewed in the direction of the string - can be pivoted up and down about a transverse axis arranged at a distance in front of the sheet, and the essentially vertical part of the guide rail arrangement located after the sheet can be telescopically displaced in a fixed vertical part of the guide rail arrangement. This allows the guide rail arrangement to give way to the post-feed pressure to a certain extent, so that excessive pressures in the packet string can be avoided.

Claim 25 is directed to a transfer device by means of which the packets can be removed from the end of the strand.

In a first embodiment of an arrangement for bringing together the packets from the strand and the partially erected blanks, the removal point of the packets from the strand and the blanks are spaced apart from each other and an intermediate channel-like guide track is required in order to transport a packet from the removal point to the transfer point in the blank (claim 26).

The carriers provided according to claim 27 ensure that the packets are conveyed in the channel-like guide track at exactly the right intervals in order to pass over the recess in the respective blank and to be able to be pressed into it properly and without disruption.

In the preferred embodiment according to claim 28, the channel-like guideway is designed as a horizontal oval.

&bull; :. Ggr;:'"'s"V":Vf■'■-·"'■'>·■'■■

According to claim 29, a pressing device can be provided, by means of which a packet can be pressed into the recess of a partially erected blank moved forward in a lower tool.

According to claim 30, the feed device can transport the packets in two parallel strands up to approximately the middle of the floor plan of the housing and two channel-like guide tracks can be provided which then transfer the packets to the vicinity of the side walls of the housing, where the production strands run.

Alternatively, however, two guide rail arrangements can also be provided, which lead from the feed device directly over the guide tracks arranged on the side walls for the tools for forming the bundles or production strands (claim 31).

In the last-mentioned embodiment of an arrangement for bringing together the packets from the strand and the partially erected blanks, the horizontal channel can be dispensed with. In this case, a transfer device is provided, by means of which the packets at the end of the strand can be moved away from the strand transversely to it in their longitudinal direction and can be transferred directly into a partially erected blank guided past in a lower tool (claim 32).

In the embodiment with the channel-like guide track, the positioning of the packages fed therein was achieved by synchronizing the drives of the conveyor device assigned to the channel-like guide track and the lower tools, which is not easy to implement.

In the embodiment with direct transfer of the packages into the partially erected blanks, achieving the correct positioning is made easier by the fact that the lower tool has means for adjusting the mutual

position of the lower tool and the packet in its longitudinal direction (claim 33).

In this way, the perfect synchronization of drives is not important, but positioning is carried out purely mechanically directly on the lower tool that is to pick up the package.

According to claim 34, the means for adjustment can comprise a pivotable lever which pushes the packet into the correct position relative to the lower tool.

Once the packet has been brought into the correct position in the partially erected blank in the lower tool, the outer carton of the cigarette paper booklet can be closed.
15

For this purpose, devices for folding and gluing the adhesive tabs can be arranged downstream of the transfer device according to claim 35.

The design according to claim 36 is particularly advantageous. This ensures that the two shorter adhesive tabs are placed over the longer

The adhesive tab is folded over and also receives glue when gluing, so that the short front sides of the cigarette paper booklet are also cleanly and firmly glued, whereas in the previous versions they are only inserted.
25

Once the booklet is glued and before the cover flap is folded over, the free longitudinal edge area of the top cigarette paper leaflet must be pulled out of the removal slot so that the cigarette paper leaflets are easily accessible for the consumer.
30

The corresponding station is arranged downstream of the devices for folding and gluing the adhesive tabs according to claim 37 and can be

Claim 38 may comprise a suction device which engages the uppermost leaflet accessible in the removal slot.

The suction device can be designed in detail according to claims 39 and 40.

According to claim 41, a device for folding the cover flap over the base panel can be connected to the suction device.

The cigarette paper booklets are sold in a simpler design, in which the cover flap is simply folded onto the base field and remains there unglued, and in a design such as that described in DE-GM 295 02 062, in which an adhesive tab is provided on the free edge of the cover flap to hold the cover flap down on the base field during the transport and handling phase. During the removal phase, the adhesive tab is opened, i.e. torn open or severed.

The embodiment according to claim 42 can be used to attach the adhesive tab.

The horizontal upper run of the lower carrier ends in the area where the uppermost sheet is sucked out and the cover flap is folded over. The books that have now been completed are now grasped by a horizontal conveyor section with rotating belts, between which the books are held under friction (claim 43).

According to claim 44, the belts extend under a stack forming station with a vertically oscillating ram which presses the bundles out from between the belts onto a collecting stack located below. 30

When the collection stack has reached a predetermined number of cigarette paper books, for example twenty-five, it is picked up by a device by means of which it can be placed in an outer carton, which, for example,

which holds four collecting stacks and in which the cigarette paper books are sold (claim 45).

In a first embodiment, the formed collecting stack is grasped by a clamp device of the stack forming station, rotated by 90° and placed in the outer carton (claim 46).

The pliers device grips the outer flat sides of the top and bottom cigarette paper booklet of the stack with its legs. The cigarette paper booklets lying between them are not guided laterally and are only held in place by the pressure of the pliers device. The pliers device works particularly well with cigarette paper booklets with non-glued cover flaps because these have a certain additional elasticity and restoring force perpendicular to the flat sides and can be easily held and handled in the entire stack of around twenty-five booklets without the closing pressure of the pliers legs having to be excessively high.

Cigarette paper books with glued cover flaps are more rigid and cannot be handled as securely in the entire stack, which is then rotated and moved in translation before being placed in the outer box. The clamp device also has the disadvantage that it has to be adjusted every time the number of books in a stack changes or the thickness of the book changes, because the height of the stack also changes.

These disadvantages are not present in an alternative embodiment according to claim 47, in which the device for depositing the collection stacks in the outer carton comprises stack-forming rails which deflect horizontally in a 90° arc, which receive the cigarette paper books between them in a braking manner, have a length which exceeds the highest collection stack present and from which a collection stack can be formed after reaching

a predetermined number of cigarette paper bundles can be pushed out against the braking effect.

The deflection required for placing the stack in the outer carton due to the vertical position of the stack during its production is not achieved here by pliers, but by the stacking rails making a curve. This allows the cigarette paper bundles to remain between the stacking rails, which means that each individual cigarette paper bundle is held in place and no free handling of an entire stack is necessary by only attacking the outermost cigarette paper bundles.

The "braking" holding of the cigarette paper books on the stacking rails can be achieved according to claim 48 by covering them with a brush or similar material. This material rests against the shorter end faces of the cigarette paper books with light pressure. The pressure is such that the cigarette paper books are held in place, but can still be pushed further between the stacking rails by one cigarette paper book thickness by adding more cigarette paper books to the stack.

In the embodiment with the 90° bend, a knife-like tool can be provided for pushing out a collecting stack, which can be moved between the stack-forming rails and then between them along the same, which tool reaches between two successive books and pushes out the downstream collecting stack along the stack-forming rails, namely into a position from which the entire collecting stack can be pushed out into the outer carton transversely to the stack-forming rails (claim 49).

According to claim 50, the pusher which presses the cigarette paper bundles down onto the stack between the belts of the belt conveyor should have the shape of a downwardly open "U" so that the measuring

· &diams; · &idigr;&idigr; ·

A serrated tool can engage between the legs of the "U" to squeeze out the cigarette paper booklet just pressed down by the pusher and also the entire downstream collecting stack when the required number is reached.
5

Particularly in the area of the 90° bend of the stacking rail arrangement, the cigarette paper books should be guided not only in their longitudinal direction, but also in their transverse direction, i.e. in the direction of the shorter side of their outline. The design according to claim 51 serves this purpose.

The entire system can be designed in two strands according to claim 52, so that the packets from two supplied strands are processed simultaneously and next to each other into bundles, which of course increases the production output considerably.

In order to prevent the inevitable noise from the tufting station from spreading into the production hall, it is recommended that the tufting part of the system be housed in a sound-insulating housing (claim 53).

The cigarette paper book, designated as a whole by 20 in Fig. 1, comprises a container 1 in the form of a flat cuboid, which contains a packet of rectangular cigarette paper sheets (not shown) folded lengthwise and laterally with the open sides mutually pushed into one another (fanned into one another). The outline of the container 1, i.e. the outline of the base area 2 with the removal slot 12 and the base part 3 corresponds to the outline of the cigarette paper sheet packet, the height 4 of the container 1 corresponds to the height of the cigarette paper sheet packet. In practice, the dimensions of the parts 2 and 3 are, for example, 24 x 70 mm and the height 4 is approximately 6 mm.

·

if it is a packet of cigarette papers containing 50 papers. In addition to the base section 2 and the bottom part 3, the container 1 has two shorter side surfaces 5,6 and two longer side surfaces 7,8. The container 1 comprises a cover sheet 10 on the base section 2, which is only connected to the container 1 at the rear longitudinal edge, i.e. at the folding edge 9, and can be opened around the folding edge 9 in the manner shown in Fig. 1.

The topmost cigarette paper sheet 13 emerges from the removal slot 12 and, as shown in Fig. 1, lies in front of the removal slot 12 on the front part of the base field 2 and can be removed there, whereby when pulled out, the next sheet comes to rest in the same way with its one longitudinal edge on the base field 2. Fig. 1 shows the removal state. In the sale or storage state, the cover sheet 10 is folded down onto the container 1 and remains in this position due to the restoring force of the fold on the folding edge 9.

Fig. 1a shows a variant in which the cover sheet 10 is provided with an adhesive tab 21 with an adhesive dot 21", which is glued to the front longer side surface 8, keeps the cigarette paper book 20" securely closed and thus performs an additional function as a tamper-evident closure.

The manufacture of the cigarette paper book 20 is based on a blank 20' made of thin cardboard, which is shown in Fig. 2 at a scale of approximately 1:1. The blank 20' comprises the rectangular base field 2' with the removal slot 12. On the four sides of the base field there are side flaps 5', 6', 7', 8', which, when the blank 20 is erected, form the side walls 5, 6, 7, 8 and accordingly have a width which corresponds to the later height 4 of the cigarette paper book 20. On both longitudinal edges the side flaps 5', 6', 7', 8' are delimited by pre-grooved folding lines, which are shown in dashed lines in Fig. 2. On the outer folding lines of the side flaps 5", 6', 8' there are adhesive flaps 15', 16', 18', which after the partial

Erecting the blank 20', i.e. after forming the depression formed by the base field 2' and the side flaps 6', 6', 7', 8' and after filling this depression with a packet of cigarette paper sheets, it is glued to the bottom flap 11', which sits on the outer fold line of the side flap 7'. On the outer edge of the bottom flap 11' there is an outer side flap 19', on which the cover flap 17' is arranged, the size of which corresponds to the outline of the cigarette paper book 20 and which produces the cover sheet 10 according to Fig. 1. For the cigarette paper book 20", the adhesive nose part 21' is provided on the free edge of the cover flap 17', to which a cutout 23' on the adhesive flap 18' corresponds.

In Fig. 3, the cigarette paper book manufacturing system is designated as a whole with 200. It comprises two feed devices 22 for the blanks 20', a two-strand feed device 24 for the packets 25 produced in a packet forming station, each of for example fifty cigarette paper sheets fanned out and folded lengthwise, and a removal device 26 for the stacks 28 of finished cigarette paper books 20, 20" placed in outer cartons 27.

The production of the cigarette paper booklets 20 from the blanks 20' and the individual packets 25 and their stack-wise packaging in the outer cartons 27 takes place in the booklet formation station designated as a whole by 30, which for noise reasons is completely surrounded by a sound-insulating housing 31 which is approximately 2 m wide and 7 m long and which has windows 32 all around the upper half through which the proper course of the processes inside the housing 31 can be observed.

The elements shown in the following figures are located inside the housing 31. The basic working sequence is shown in a highly schematic manner in Fig. 4a and 4b. Fig. 4b is intended to follow on from Fig. 4a on the right.

The feed devices 22 of Fig. 3 are symbolized in Fig. 4a by a corresponding arrow. Inside the housing 31, near the front 31' and the back 31" of the housing, two production lines are formed, each with two oval, endless guide tracks 35, 36, which run in the same vertical plane. Each feed device 22 serves one production line. Upper tools 37 can be moved along the guide track 35 on link chains in the direction of the arrow 38. The guide track 35 runs approximately horizontally in its lower run 39 on a working section 40. The length of the working section 40 corresponds approximately to the distance taken up by four or five upper tools 37.

The upper run 49 of the guide track 36 runs horizontally just below the lower run 39 of the guide track 35. Lower tools 47 can also be moved along the guide track 36 on link chains in the direction of arrow 48. The lower tools 47 are the same distance apart from each other along the guide track 36 as the upper tools 37 on the guide track 35. In addition, it is ensured that in the working section 40 each upper tool 37 runs exactly above an associated lower tool. Only a few upper tools 37 and lower tools 47 are shown by rectangles. The others are only indicated by their center lines. In fact, however, the guide tracks 35, 36 are occupied by tools along their entire length.

The tools 37, 47 are designed to be complementary and work together to form a recess in the working section 40 by folding up the side flaps 5', 6', 7', 8' of the blank 20' according to Fig. 2, into which the packets 25 of cigarette paper sheets are inserted at a later time.

From Fig. 4a it can be seen that the lower guide track 36 projects longitudinally on both sides over the upper guide track 35. On the left side in Fig. 4a, i.e. in the area of the feed device 22, the blanks 20' are placed on the lower tools 47 and are horizontally guided in the direction of the

► t · ·

Arrow 48 is conveyed further to the right until it comes between the tools 37, 47 in the working section 40. The movement in the direction of arrows 38 and 48 is continuous, running concurrently at an adjustable speed that remains constant once the setting has been made. In the working section 40, a stamp comes down from the upper tools 37, which presses down the base field 2' of the blank 20' lying on the lower tool 47 and in the process erects the side flaps 5', 6', 7', 8'. For this reason, this area can also be referred to as the erecting station 100. The flaps 15', 16', 11', 18' adjoining the side flaps 5', 6', 7', 8' on the outside remain essentially parallel to the base field 2', so that a recess for receiving a packet 25 is formed above it. The blanks 20' come out of the working section 40 in this partially erected state and are taken to the right by the lower tools 47, which are moved further horizontally in the guide track 36 beyond the area of the guide track 35, as shown in Fig. 4a.

At the level of the part of the guide track 36 which extends beyond the guide track 35 on the right as shown in Fig. 4a, the feed device 24 enters the interior of the housing 31, which feeds two parallel strands S ₁ S of packets 25 with cigarette paper sheets. The entire booklet forming station 30 operates, as mentioned, in two strands. The guide tracks 35, 36 are arranged in pairs next to each other in the housing 31. One strand S of packets 25 serves to supply one arrangement 35, 36, the other strand S to supply the other arrangement 35, 36 not shown in Fig. 4a and 4b.

As can be seen from Fig. 3, the packet strands S enter the interior of the housing 31 at a certain height. They run essentially horizontally in the housing 31 and are then guided downwards in an arc B as shown in Fig. 4a. The cigarette paper packets 25 are taken away from the lower ends 41 of the two strands S and, in the embodiment shown, are taken one after the other in a horizontal guide track 42, initially to the left as shown in Fig. 4a, in order to

then to be brought in an arc, which is not visible in Fig. 4a, over a partially erected blank 20' carried on a lower tool 47. This will be described with reference to Figs. 6 to 8. The arrow 43 indicates the transfer device by means of which a packet conveyed in the channel-like guide track 42 is introduced from the guide track 42 into the recess formed in the blank 20' running underneath.

After the packets 25 have been inserted into the respective recess of the blank 20' at point 43, the longitudinal adhesive tab 18' located on the long side tab 8' is folded over the packet 25 in the recess at point 33. At point 34, the two adhesive tabs 15', 16' located on the shorter side tabs 5', 6' are folded over the packet, specifically over the corners of the folded adhesive tab 18'. The adhesive tabs 15', 16', 18' are glued, and the bottom tab 11' is placed over them at point 46 and glued to the adhesive tabs 15', 16', 18', so that the partially finished cigarette paper booklet 20 is now closed all around. In this state, the blank 20' passes from the lower guide track 36 into a horizontal straight rail guide 44, in which further conveyance takes place at a constant speed in the direction of arrow 45 (Fig. 4b). The "top" sheet of the packet 25 in the sense of Fig. 1, which is actually located at the bottom in the rail guide 44, is exposed at the removal slot 12, but is still completely in the cigarette paper booklet 20. The "top" sheet is difficult to grasp in this state. For this reason, the top sheet must be pulled out of the removal slot 12 so that it comes to lie with the front longitudinal edge 13 on the top of the base field 2 in the manner shown in Fig. 1.

This pulling out of the "top" sheet is done by means of a suction device 50. When the suction device 50 has pulled out the top sheet, the cigarette paper book 20 is almost finished.

In a cigarette paper booklet 20 according to Fig. 1, only the side flap 19' is folded over at point 51 and the cover flap 17' is folded over onto the base field 2' in order to offer a certain degree of protection for the topmost cigarette paper leaflet lying openly on the base field 2' as shown in Fig. 1. The restoring force of the fold holds the cover flap 17' in this position.

However, in the case of a cigarette paper booklet 20" according to Fig. 1a, after the "top" sheet has been sucked out by means of the suction device 50 at a closing station 58, the adhesive nose 21 is folded over and glued to the front side surface 8 of the cigarette paper booklet 20". To do this, after the cover flap 17' has been folded over, the front side surface 8 is provided with an adhesive point 21" and the nose part 21 is placed over it with a rail and the adhesive is pressed on with an eccentric wheel. This is not shown in detail in Fig. 4b.

After passing the point 51, the cigarette paper books 20 or 20" are finally finished and pass from the guide track 44 onto a belt conveyor 52, which has two belts 53 running endlessly in the same horizontal plane, the inner strands 53' of which are opposite one another and run at the same speed as the conveyor and are spaced apart by the width of a cigarette paper book 20, 20' and hold and carry it with friction between them (Fig. 19, 20). The belts 53 have a friction-promoting structure on their outer sides.

The reason for the transition to the belt conveyor 52 is that the conveyed cigarette paper bundles 20 can easily be pressed out vertically between the belts 53, which is done by the vertically oscillating pusher 54. The pusher 54 presses an incoming cigarette paper bundle 20, 20' downwards into a stacking device 55 with two stacking rails 56, which grasp the cigarette paper bundles 20, 20' at the narrower end faces 5, 6 and, under friction, but still perpendicular to their

Flat side movable, hold firmly. When a predetermined number of cigarette paper bundles 20, 20' are present in the stack forming device 55, the collecting stack 28 is grasped by a corresponding device and deposited in accordance with the arrow 57 into a waiting outer box 27 (see also Fig. 3), which is then conveyed out of the housing 31.

The elements described above are present twice in the system 200, namely on the front side 31' and the back side 31" of the housing 31 shown in Fig. 3. The system 200 has two parallel production lines.

In the following figures, some of the elements shown only schematically in Fig. 4a and 4b are shown in more concrete form.

In Fig. 5, the erection area 100 of the upper guide track 35 is shown in more detail. The upper tools 37 are guided over the guide track 35 on a link chain 35', which rotates endlessly over two deflection wheels 60 and 61 rotating around parallel horizontal axes. In the working section 40, the lower run 39 of the guide track 35 lies above the upper run of the guide track 36, on which the lower tools 47 advance from left to right according to the arrow 48 at the same speed as the upper tools 37. On the left edge of Fig. 5, a separating device 62 according to EP patent 265 870 can be seen, which has a circular disk 63 rotating around a horizontal axis with three arms 64 distributed over the circumference and arranged parallel to the axis, which have rubber suction cups 65 at their free ends, by means of which one is taken from the strand of blanks 20' conveyed by the feed device 22 (Fig. 3) and placed on a lower tool 47, which then conveys the blank 20' from left to right under an associated upper tool 37 according to Fig. 5.

The upper tools 37 each comprise a holder 66 which is carried along on the link chain 35' and on which a stamp part 67 is spring-guided, which comprises a stamp 58 in the working section 40 below the respective upper tool 37, which can be inserted into a corresponding recess on the upper side of the lower tools 47 and in the process presses down the base field 2' of the blank 20' while folding up the side tabs 5', 6', 7', 8' (Fig. 2).

The stamp part 67 has a guide roller 68 on its upper side, which comes to rest on a point on a machine-fixed inclined guide curve 69 when the upper tools 37 rotate in the direction of arrow 38, as shown for the guide roller 68' of the upper tool 37'. When the path continues in the direction of arrow 38, the stamp part 67 is pressed down relative to the holder 66, the springs being compressed by the guide roller 68", as shown for the upper tool 37". At this point, the stamp part 67" has reached its lowest point, and the stamp 58, which has been immersed in the blank 20' and is subject to considerable friction after the side flaps 5', 6', 7', 8' have been raised, must now be pulled up again. This is done by means of another machine-fixed guide curve 70, which reaches under the guide roller 68" in the manner shown in Fig. 5 and, as it rises in the direction of the arrow 38, slowly pulls it up again with the stamp 58 out of the respective lower tool 47.

The blank 20', which is partially erected to form a depression delimited by the base field 2' and the side flaps 5', 6', 7', 8', remains on the respective lower tool 47 and is conveyed further by the latter in the direction of the arrow 48 to the right out of Fig. 5 in order to then be filled with a packet 25 of cigarette paper leaves.

A first device for this purpose is shown in Fig. 6 to 8.

Fig. 6 shows a view from the inside of the housing 31 towards the point where the feed device 24 brings the two strands S ₁ S of cigarette paper packets 25. The strands S ₁ S are guided in the housing 31 in a guide rail arrangement 90 which in the embodiment runs diagonally downwards and after entering the housing 31 forms a downward-running arch B and then merges into a vertical section 90" with a strand section S'. The packets 25 lie flat side to flat side against one another. The arch B lies in a plane perpendicular to the flat sides and parallel to the shorter plan sides. The guide rail arrangement 90 is formed by corresponding rods 71 and rails 77 , each of which determines a guide cross-section corresponding to the outline of the packets 25. The packets 25 are each removed individually from the lower ends 41 (see Fig. 4a) of the strands S, S according to Fig. 6 from right to left and transferred into channel-like horizontally adjacent guide tracks 42 in which the packets 25 are guided in their Longitudinal direction in the direction of arrow 45' initially pushed forwards against the main conveying direction 45. One channel-like guide track 42 is provided for one production line of the machine near the front 31' of the housing, the other guide track for the other production line near the rear 31". The two strands S ₁ S end with their vertical strand sections S',S' according to Fig. 3 approximately in the middle of the housing 31, seen perpendicular to the guide tracks 35,36. The channel-like guide tracks 42 serve to move the packets 25 from the respective lower ends 41 located in the middle to the transfer points located near the front 31' or the rear 31" into the partially erected blanks 20' on the lower tools 47. The guide tracks 42 each run in a horizontal 180° arc from the center to the outside, divert the packets 25 of a strand S into the main conveying direction 45 and guide them over the partially erected blanks 20' approaching in the lower tools 47 in the main conveying direction 45, into the recess of which they are pressed down by suitable design of the rails forming the guide tracks 42.

&bull;&diams; ·

Fig. 8 shows the point 43 at which the packets 25 are introduced from the channel-like guide track 42 into the recesses of the partially erected blanks brought up on the lower tools 47. The guide track 42 shown in Fig. 8 runs in an endless horizontal curve and serves to supply the production line located on the rear side 31" of the housing 31 according to Fig. 3. The packets 25 are carried at the correct distance by drivers 83 on a link chain running above the guide track 42, which is deflected by the aforementioned 180° around a wheel 83' only indicated in Fig. 8. After the respective packet 25 has been pressed down from the guide track 42 into the recess of the blank 20', the respective blank 20' is "filled" but not yet closed.

It is important for the proper functioning of the system that the strands S ₁ S of the packets 25 are always filled properly. If the packets 25 do not follow closely together, the removal process from the lower end 41 of the respective strand is disrupted. If the packets 25 are completely absent, the produced packets are not filled. If the feed pressure in the strands S ₁ S becomes too high, there are also difficulties with the removal at the ends 41.

For these reasons, a simple but effective device for controlling the conditions in the respective strand S of the packets 25 is provided on the upper side of the sheet B (Fig. 6). The device comprises a flexible control strip 72 made of metal or plastic which rests in the region of the sheet B on the upper side of the respective strand S in the longitudinal direction thereof and which is mounted in a machine-fixed manner at its end 73 located upstream of the strand. The control strip extends over the sheet B and rests at its lower end 74 on the upper side of the strand S under the effect of a weight 75. The radial height of the guide cross-section of the guide rail arrangement 90 is greater in the region of the sheet B than the width of the packets 25, seen in the direction of the shorter plan side.

The packets 25 therefore have radial play in the guide rail arrangement 90, in relation to the sheet B. Depending on the feed pressure, the position of the strand S in the guide rail arrangement 90 can change slightly in this way. If the course of the top of the strand S changes as a result of the changing filling of the strand S, the control strip 72 follows this change in course. This is illustrated in more detail using the further developed embodiment 11 to 13. This changes the distance of the control strip 72 from a machine-mounted proximity sensor 76, which triggers a corresponding signal. This signal can be used to actuate the driving device shown in Fig. 7.

Fig. 7 shows the lower end 41 of a strand S of cigarette paper packets 25 and the beginning of the channel-like guide track 42. A ratchet rail 78 is attached under the end 41 of the strand S and can be pivoted about its right-hand end 78' in Fig. 7 and is normally arranged approximately horizontally. The ratchet rail 78 is held in the horizontal position shown by a pneumatic cylinder 79 which acts from below against its right-hand end according to Fig. 7. A ratchet 80 is provided which is moved horizontally in strokes and can be pivoted up and down about its right-hand end 81 according to Fig. 7. The latch 80 rolls over a roller 82 on the latch rail 78 and is held up by the latter in such a way that the left-hand end face 80' of the latch 80 comes to rest on the lowest packet 25 and pushes it lengthwise in the direction of the arrow into the channel-like guide track 42 as shown in Fig. 7. However, if too few packets 25 follow and the proximity sensor 76 emits a corresponding signal, the cylinder 79 drops and with it the latch rail 78 drops downwards, as indicated by the dashed line. The latch 80 then also pivots downwards around the point 81 and runs past the lowest packet 25 without coming into contact with its end face. No more packets 25 are then pushed into the channel-like guide track 42. At the same time, the acceptance of the blanks is interrupted for 20' to avoid the production of empty books.

&diams; · ·&diams;« «· t

The latch rail 78 can also be arranged in reverse so that it can be pivoted about its left end as shown in Fig. 7.

Fig. 9 shows a modified embodiment of the area of transfer of the packets 25 from the strand S into the partially erected blanks 20' compared to Figs. 6 to 8. The difference to the embodiment according to Figs. 6 to 8 is that the ends of the strands S are no longer located in the middle of the housing 31, but directly above the respective guide track 36 of the lower tools 47. The channel-like guide tracks 42 which deflect by 180° are therefore no longer required in order to get the packets 25 into the partially erected blanks 20' in the lower tools.

Here too, as in the embodiment according to Fig. 6, a guide rail arrangement 90 is provided which has a first horizontal section 90', which is followed by the arch B, which then merges into the vertical guide rail section 90". The guide 90' is mounted so that it can be pivoted up and down about an axis 99 at the beginning. At the other end, the guide 90' rests on the arch B. B and 90" are firmly connected to one another and are moved up and down vertically. The vertical section 90" slides telescopically in a fixed guide rail section 90'", at the lower end of which the packets of the strand S are removed. The pivot angle is limited and is only a few degrees, so that there are no constraints at the transition 90", 90'".

In the embodiment according to Fig. 9, a control strip 72 is also provided in the area of the arch B on its upper side, which is held fixed to the housing at its upper end 73. At its lower end 72', approximately at the height of the arch center, the control strip 72 is angled radially outwards and carries there a switching piece 75 designed as a small cuboid weight, which projects into the space between proximity sensors 76', 76" arranged one above the other. This can be seen in detail in Figs. 11 to 12.

&bull; · t»t «· t

In Figs. 10 to 12, vertical sections through the middle of the width of the control strip 72 are shown, from which the function of the control strip 72 can be seen. Fig. 10 shows the normal case. The line S of the packets 25 runs under normal post-feed pressure in such a way that the packets 25 float with their lower or, with respect to the sheet B, radially inner edge at a certain small distance A ₀ above the bottom 77' of the local rail 77 of the guide rail arrangement 90. In the area of the arch B, the control strip 72 rests on the outside of the strand S formed by the outer edges of the packets 25, and the switching piece 75 is located in the middle between the proximity sensors 76' and 76". However, if the post-feed pressure drops, the packets 25 rest on the bottom 77' of the rail 77 as shown in Fig. 11, so that the distance A ₀ disappears, and the control strip 72 is lowered. The switching piece 75 is located immediately above the lower sensor 76". The signal from this causes the parts B and 90" to move vertically downwards until the packets 25 lift off the bottom 77' and thus raise the control strip 72 until the switching piece 75 is located between the sensors 76' and 76", which indicates that the post-feed pressure has normalized.

Fig. 12 shows a case in which the feed pressure in the strand S is too high. The strand S then has the tendency to take on the largest possible curve and then lifts off the bottom 77' of the rail 77 in the manner indicated, so that a radial distance A arises which is clearly greater than A ₀ . The guide strip 72 is thereby lifted and the switching piece 75 is displaced towards the upper proximity sensor 76' (Fig. 12).

The proximity sensors 76' and 76" then emit a correspondingly modified signal, which can be used for control purposes in such a way that the state according to Fig. 12 is returned to that according to Fig. 10.

&bull; · t &bull; ■·

The situation according to Fig. 12 can arise because the feed pressure in the strand S becomes too high. This alone can cause the strand S to lift off the bottom IT of the guide rail 77 due to the bend B in the manner shown in Fig. 12. The upward displacement of the switching piece 75 in the manner shown in Fig. 12 can also arise because too many packages are fed in and cannot be quickly removed at the lower end of the vertical guide rail section 90'". The guide rail arrangement 90 then lifts up while pivoting about the axis 99, whereby the sections 90" and 90'" slide into one another like a telescope and the effect shown in Fig. 12 is also achieved.

The transfer of the lowest packet 25 into the partially erected blank 20' is accomplished by means of a servo motor 93, which controls a removal and transfer carriage 95 via a tie rod 94, which can be moved parallel to the advance direction 45 of the lower tools, grasps the respective lowest packet 25 on the lower guide rail section 90'" and presses it down into the partially erected blank 20' in the lower tool 47 running just below it.

In Fig. 13, a lower tool 47 is shown in perspective, which carries the partially erected blank 20' in a recess on its upper side, which was created by the penetration of the stamp 58 from above according to Fig. 5. The walls 5, 6, 7, 8 are already perpendicular to the base field. The packet has not yet been inserted. The removal slot 12, which is open at the bottom, can be seen.

In Fig. 14, the packet 25 has just been inserted. In order to optimize the position of the packet 25 on the lower tool 47, a lever 98 is provided which can be pivoted against the force of a spring 97 about a horizontal axis 96 arranged transversely to the direction of movement of the lower tool 47, which lever 98, when pivoted upwards, comes to rest in a stop position on the front side 25' of the packet 25 in the manner shown in Fig. 15.

comes and the packet 25 is positioned precisely relative to the lower tool 47 so that the adhesive tabs 15', 16', 18' can be placed around the packet 25 without interference. This type of positioning replaces the positioning by synchronizing the drives of the lower tools 47 and the drivers 83 in Fig. 8, which is more difficult to adjust precisely.

In Fig. 16, the right end of the guide track 36 with the deflection wheel 91 for the lower tools 47 can be seen. To the right of the deflection wheel 91, the suction device, designated as a whole by 50, is shown, which pulls the uppermost cigarette paper leaf out of the removal slot 12 of the now closed booklet 20. It comprises a circular, fixed disk 101 with an endless guide groove 84 provided on the front. In front of the disk 101, a star 85 with eight radial arms 86 rotates, at the ends of each of which a suction head 87 is attached, which can be seen in detail in Figs. 16 and 17. Each suction head 87 has a lateral bearing pin 88 parallel to the axis of the star 85, which is screwed to the end of the respective arm 86 and about which the suction head 87 can be pivoted. On the side facing the fixed disk 101 (i.e. the rear side according to Fig. 18), the suction head 87 has a guide roller 89 which engages in the groove 84 and by means of which the suction head 87 is pivoted in a certain way about the bearing pin 88 as the star 85 rotates. By interacting with another guide curve on which a guide roller 89' rolls, a suction device 92 which is spring-loaded on the suction head 87 can also be displaced radially so that it can be brought into contact at the correct point on the surface of the uppermost leaflet accessible through the removal slot 12. The suction device 92 comprises a row of nozzle openings 93 which can be seen in Fig. 18 and which can be connected to a vacuum via a hose 94 (Fig. 17). The connection is made at a precisely selected time which allows the uppermost leaflet to be grasped by the suction nozzles 93 and pulled out into the position shown in Fig. 1.

After the topmost sheet has been pulled out, the cover sheet 17' of the blank 20' is folded over, whereupon the booklet 20 is completed if it is the simple booklet 20 according to Fig. 1. The booklet 20" with adhesive nose 21 according to Fig. 2, however, still passes through a closing station indicated in Fig. 4b by the dashed arrow 58. After that, both types 20, 20" of cigarette paper booklet - as shown in Figs. 19 and 20 - run into the belt conveyor 52, which belongs to a stack formation station and whose belts 53 grasp it between them at the longer side walls 7 and 8 with their opposite strands, which run together in the direction 45, and take it along under friction. Above the belts 53, 53, the vertically oscillating ram 54 (Fig. 4b) is provided, which is driven by a crank rod 96 and reaches between the strands 53', 53' of the belts 53, 53 in order to press a booklet 20, 20" conveyed between them downwards into a stack-forming device 55, which has already been mentioned in connection with Fig. 4b.

As can be seen particularly from Fig. 20, the tufts 20, 20" run between the strands 53' of the belts 53 until they hit a fixed stop 102, which stops their further movement in the conveying direction 45. At practically the same moment, the vertically oscillating ram 54 comes down from above, which is essentially plate-shaped and moves in a plane perpendicular to the flat side of the cigarette paper tufts 20, 20" and parallel to the longer sides of the cigarette paper tufts 20, 20". At the lower end, the ram 54 has the shape of a downwardly open "U" with legs 102', the widened lower ends 103 of which rest on the cigarette paper tufts 20, 20" and press them out between the strands 53' of the belts 53 and down between the vertical stacking rails 56, 56 of the stacking device 55 (see Fig. 4b). The plunger 54 then goes up again and the timing is such that it is down again just when the next cigarette paper bundle 20,20" has reached the stop 102.

The stacking rails 56 extend from below the belts 53, 53 and run in planes parallel to the shorter sides of the plan of the book. They are covered on the sides facing each other with a brush material 104, a solid velour material or the like (see Fig. 21, 23) and are spaced such that the respective cigarette paper book 20, 20" is grasped and held on its shorter side surfaces 5, 6 (Fig. 1), but can still be moved in the conveying direction 105 of the ram 54. The ram 54 therefore moves up and down constantly and with each stroke presses a cigarette paper book 20, 20" from above between the stacking rails 56 to its lower end position, whereby the entire stack part introduced up to that point between the stacking rails 56, 56 is pushed further down by the thickness of a cigarette paper book 20, 20".

When the desired number of cigarette paper bundles 20, 20" has accumulated between the stack-forming rails 56, 56, for example twenty-five, a pliers device 106 reaches with its legs 107, 107 parallel to the plane of the drawing in Fig. 21 in the direction of the arrow 108 between the stack-forming rails 56, 56 and grasps the formed stack of cigarette paper bundles 20, 20" with the legs 107, 107 from below or above.

The legs 107,107 are brought together in the direction of arrow 109, so that the stack 120 is slightly compressed in the direction 105 and can be handled without further guidance.

The stack 120 is then pulled out between the stack-forming rails 56, 56 by pulling back the clamp device 106 in the direction of the arrow 110 and is pivoted about an axis perpendicular to the plane of the drawing in Fig. 21. The contact pressure is reduced, but only to such an extent that the stack 120 remains in the clamp device. After the stack 120 has reached a horizontal position (similar to Fig. 22), it can be placed in an outer box 27 (Fig. 4b), if necessary after carrying out a few further translational movements, depending on the design conditions, whereby the clamp device 106 releases the stack 120. If there are enough

When enough cigarette paper books 20,20" have accumulated between the stacking rails 56,56, the pliers device 106 moves back between the stacking rails 56,56 in its upright position according to Fig. 21 in order to grasp the new stack 120.

Fig. 23 shows a cross-section through the stack 120, from which it can be seen even more clearly how the stack-forming rails 56 grasp the cigarette paper books 20, 20" at their short side surfaces 5, 6.

The device 115 of Fig. 22 also comprises two stacking rails 116, 116 which are opposite one another at the ends of the cigarette paper books 20, 20", the cross section of which is that of a flat "U" and which are provided at least on the bottom of the "U" with a coating of a brush material 104 which grips the ends 5, 6 of the cigarette paper books 20, 20" and ensures that they cannot fall freely through between the stacking rails 116, 116. The open sides of the "U" face one another. The first vertical part of the stacking rails 116, 116, which extends from below the belts 53, 53, is followed by a 90° bend 113, by which the stack 120 can be deflected into the horizontal. From a horizontal part 114 of the stack forming rails 116,116, the stack 120, indicated by dashed lines in Fig. 22, can be pressed by a pusher 125 in the direction of the arrow into an outer carton 27 located underneath. The 90° bend 113 saves a movable clamp arrangement as shown in Fig. 21. Outside the horizontal region 114, the stacking rail arrangement has the U-shaped cross-section shown in Fig. 24, which not only guides the cigarette paper bundles 20, 20" in their longitudinal direction, but also in the transverse direction with the legs 116', 116', because the stacking rails 116, 116 are U-shaped. Such guidance in the transverse direction is necessary because the stack 120 has to travel the sheet 113 and radial forces are also exerted on the cigarette paper bundles 20, 20".

A knife-like tool 117 can be used to push a formed stack 120 into the horizontal part 114. When the ram 54 is at the top, it is pushed forward in the direction of arrow 118 over the top cigarette paper book between the stack-forming rails 116, 116 and is then moved downwards in the direction of arrow 119, taking the stack 120 with it, until the stack 120 has completely passed into the horizontal part 114. The pushing forward of the knife-like tool 117 takes place when the ram 54 is in its upper stroke range. The next cigarette paper book 20, 20' pressed out between the strands 53', 53' remains hanging on the brush material 104 in the area of the uppermost cigarette paper book 20, 20" in Fig. 22 due to friction when the knife-like tool performs the movement in the direction of arrow 119, whereupon a new stack is formed. The knife-like tool 117 is returned to its upper position outside the stack-forming rail arrangement 116, 116 until the next stack is complete again.

It is important that the tools used to produce the Büchel 20 and the Büchel itself always work and run in the same direction so that no energy losses or wear-prone situations occur due to many back and forth movements. The Büchel 20,20" are produced in a continuous flow.
