Arrangement for storing rod-shaped articles of the tobacco processing company Industry

The invention relates to an arrangement for storing rod-shaped Articles of the tobacco processing industry between a production machine and a further processing machine with a collecting container of variable capacity for Receiving a stack of rod-shaped articles of limited height, with one associated with a first end wall of the collecting container Outlet for the articles, a bottom of the collecting container adjoining the outlet and designed as a movable belt, a reciprocable second end wall disposed opposite the first end wall and a feed for the Items.

If in the tobacco processing industry production machines, e.g. cigarette, cigarillo, filter cigarette or filter manufacturing machines, with further processing machines, e.g. packing machines or distribution devices for pneumatic Conveying the articles, directly linked, is used to avoid shutting down the production machines in the event of malfunctions in the further processing machines Intermediate links in the form of storage devices. For this Storage facilities are available which, when the machines are working properly, provide an as immediate as possible Ensure passage of the article, while in case of malfunctions in the further processing machine one in its capacity Changeable collecting container, e.g. in the form of a sack buffer, which holds articles that have been produced further. Such a storage device is shown, for example, in German patent specification 1,532,271. On one Conveyor belt v / earths a container of cigarettes. There is a felt finger at the discharge end of the conveyor belt

provided that the orientation of the via an end roller the conveyor belt is intended to maintain the article. If the level of the articles in your container has now dropped somewhat, in this way, the articles coming from the conveyor belt fall freely into the container for a certain distance. At the Can hit the items in the container they lay down easily, which happens especially when if there are filter cigarettes in the container. Due to the pressing of the superimposed filter cigarettes, their tobacco rod is more compacted than theirs Filter end so that the filter cigarettes on top assume an inclined position. But this favors a Crossing the fed cigarettes. Below the discharge end of the conveyor belt are the container Associated with photocells, a base band and a side wall attached to this one associated with the container Control buffers. When falling below a certain Mve off, the volume of the buffer is reduced until the pressure exerted on the article reduces the volume of the buffer The level in the area of the discharge end of the conveyor belt rises. Here, at the height shown, the saved Article already required a considerable amount of pressure, but this again required the removal of the article by the one shown narrow outlet openings difficult.

Another embodiment of a memory arrangement is shown in the German Offenlegungsschrift 1.957.002. here the articles are placed in a storage supply from below pressed in, reducing the risk of the Article is avoided. On the other hand, however, the amount of a supply formed in this way is limited since the articles against the weight of the arti ^ lying above the confluence must be pressed into the supply. With such sensitive items as cigarettes, you can put the strain on the Article when pushed into the stock but not loaded

increase lovingly, so that one in terms of the supply level is limited and to maintain sufficient buffer space Relatively long and therefore complex and space-consuming "Sp ei rather facilities" have to be built. This is then also evident from the cited publication.

The invention has for its object to design an arrangement of the type mentioned in such a way that the Articles can be stored in a relatively small space, i.e. in a stack of relatively great height, and that the Articles are brought gently and with a defined position in the collecting container, so that disturbances in the Production process can be prevented.

This object is achieved according to the invention in that the feed means conveying means for frictional transport the article has in the collecting container and opens into the collecting container from above.

A friction Transporti the article even in the collecting container to a further characteristic of the invention, particularly opposing, continuously revolving conveyor, the individual articles are suitable according to gathering with each other are arranged. A space-saving 'arrangement of the storage device is realized by attaching the device above the production or processing machines, wherein in a further embodiment of the invention, the conveyors are designed as conveyor belts in a way that gently treats the articles and are guided around deflection rollers in such a way that the articles are guided from a substantially upward conveying direction into a substantially downward conveying direction. In order to be able to fully utilize the available height of the collecting container, ie to obtain a constant, maximum level of the articles in the collecting container, according to a further feature of the invention, FIG

_ ₄ _ 309883/090

Stw .: Flow magazine sack buffer summary - A 1206 Bergedorf, April 12, 1973

The collecting container in the area of the confluence of the feed has an upper limit. Because of the sensitivity of the articles, it is advisable to place the articles in the collecting container where, as a result of the removal of articles through the outlet or by increasing the capacity of the collecting container, the level of the articles first drops, i.e. the supply of articles into the collecting container least resistance is offered. In a further development of the invention, the feed therefore opens into the collecting container perpendicularly above the border area between the outlet and the bottom belt. In order to be able to introduce the articles into the collecting container in a guided manner at different levels of the articles in the feed area, so that they do not fall freely after being released by the conveyor belts after being released and then take an undefined position on the articles in the collecting container, is another Embodiment of the invention, the conveyors are assigned a guide for the articles, which guides the articles to the articles in the collecting container and is designed to be conductive and its length can be adapted to the level of the articles in the collecting container Guide from a stationary wall and a stationary wall, the latter being formed in an expedient embodiment of the invention by a loop made of elastic material. Furthermore, it is appropriate for the gentle treatment of the product to provide a sensitive possible measuring means for detecting the quantity of items contained in the collection, so that a strong squeezing of the product is avoided.

According to a further feature of the invention, the first end wall is therefore ausgebil det as a pressure-sensitive button. An increase in the sensitivity of the above-mentioned measuring device is achieved in a further embodiment of the invention in that the feed in the region of its confluence with the collecting container has a conveying direction with a

" ⁵ " 309883/0903

Stw .: flow magazine sack buffer summary -. A 1206 Bergedorf, April 12, 1973

Having component toward the first end wall. In detail According to a further feature of the invention, a quickly responding and stable control arrangement is implemented by that the button has a limit switch, which via contactless control means with a for driving Floor band and movable second end wall serving rotating field magnets connected is.

As already described at the beginning, filter cigarettes are stored in a supply by the weight of the ones lying on them Squeezed filter cigarettes, being squeezed together at the tobacco rod end more than at the filter end. this would lead to a considerable inclination of the upper layers of cigarettes, especially with the desired relatively large stack heights lead, which in turn involves the risk of cross-laying cigarettes that have been fed in. This will be discussed in further Embodiment of the invention avoided in that the first end wall and one wall of the outlet and an opposite one Wall arranged at least in the area of the outlet in the longitudinal direction of the article diverging from one another are. This gives the cigarette layers in the area of the outlet such an inclined position that the cigarette layers Assume a horizontal position in the area of the confluence of the feeder.

Storage arrangements of the type mentioned at the beginning are arranged in a space-saving manner above the production or further processing machines, and one of them is multilayered The flow of articles is conveyed downwards to the further processing machines. Many further processing machines, e.g. high-performance packing machines, require the supply of two or more article streams, including an article stream directly Before the. Further processing machine divided into two or more streams. For this it is known in one vertically arranged conveyor shaft a junction in front of

in the middle of which a roof-shaped deflector plate is fastened, against which the articles are conveyed and after the Pages are diverted into sub-shafts. If the storage device serving as a feeding conveyor is arranged relatively high, in the case of the sub-arrangement described, disturbances often occur in the area of the junction. These disorders are due on the one hand to the great pressure with which the cigarettes are pressed against the deflector plate and, in the case of filter cigarettes, on the other hand, on the inclined position of the cigarettes in the area of the baffle, which a cigarette can hit the tip of the deflector in an inclined position and be crushed. For the high pressure is the weight of the high stack of cigarettes in the conveyor shaft, which is also responsible for the inclined position of the Cigarettes caused because filter cigarettes on their cigarette stick end are compressed more than at their filter end. To avoid disruptions in the production process ■ an arrangement of the type described above is to be designed in such a way that also article flows from one relatively high arranged feeders can be divided smoothly.

This is achieved in a further embodiment of the invention that the outlet of the collecting container in a For conveying a flow of articles, the downward conveyor opens into a lower junction, whereby the distance between the collecting container and the junction is greater than the width of the flow of articles, the junction is the one Having article flow dividing roof-shaped deflection means and the downward conveyor in its upstream of the deflection means Area is inclined in such a way that it has a horizontal conveying component «

The incline of the down conveyor increases the height of the the deflecting agent is relatively stressful to the cigarette layer

309883/0903

Stw .: Flow magazine sack buffer summary - A 1206 Bergedorf, April 12, 1973

kept small, so that loosening up the flow of articles in the area of the junction by shaking is unnecessary. According to According to a further characteristic of the invention, therefore, the deflecting means is arranged in a stationary manner. In further development of the invention is the downward conveyor as a conveyor shaft formed with stationary walls, which is connected by the junction with partial shafts.

Packing machines for packing cigarettes are often limited by the time required for cigarette block formation limited in their performance. An increase in performance is then by connecting several of them next to each other or one behind the other Blocking devices possible. In a particularly advantageous application of the invention, the junction is upstream of a block-forming device of a packaging machine.

As already stated, another source of interference is the slanting of compressed filter cigarettes. To at least A defined position of the cigarettes in the area of the roof-shaped deflecting means is also possible Formation of the invention Side walls of the conveyor shaft and the sub-shafts diverging in the longitudinal direction of the article arranged to each other.

It is often desirable to check the articles before they are further processed, for example before they are packaged. It is true that the tightness of the wrapping material, the strength of the heads of the articles, etc. can be monitored automatically on the production machines, but other properties can only be checked by visual inspection. Thus, for example, the proper functioning of printing devices for printing the wrapping material with trademarks etc. is checked by observing the manufactured articles, so that a run out of color or other malfunctions can be recognized in good time. - 8th -

In order to enable a visual inspection of the article in an arrangement of the type described above, is in further Formation of the invention between a delivery end of the downward conveyor and the receiving station, a horizontal conveyor arranged.

In order to carry out the above-mentioned visual inspection, it is not necessary to check every cigarette. It is Quite sufficient, in the case of a multi-layer article flow, only to inspect the upper row of articles to take. In a further embodiment of the invention, the horizontal conveyor is therefore open at the top. In a constructive way In a simple further development of the invention, the horizontal conveyor is designed as an endlessly revolving conveyor belt. If possible, one should be on the horizontal conveyor constant amount of articles must be available, so that on the one hand the flow to the receiving station is not tears off, but on the other hand not too many articles accumulate on the horizontal conveyor. In further development According to the invention, the receiving station is therefore a monitoring device assigned for supplied articles that are connected to a drive of the horizontal conveyor to control the Article supply to the receiving station and the removal of articles from the downward conveyor is connected.

In order to prevent the upper filter cigarettes from tilting in the area of the junction 47 in the collecting container 1, As can be seen from FIG. 3, the end wall 19 and a wall 58, which is assigned to the downward conveyor 4 and which the end wall 19 continues downward, and an opposite wall 59, also assigned to the downward conveyor 4, in the Area of the outlet 18 arranged diverging from one another in the longitudinal direction of the filter cigarettes.

The downward conveyor 4 with its in the longitudinal direction of the filter cigarettes 2 diverging side walls 58 and 59, which the collecting container 1 of the storage device as a feed conveyor is upstream, is as inclined conveyor shaft 61, which consequently has a horizontal conveyor component, formed in which the filter cigarettes 2 are conveyed downward due to gravity. The block forming device 7 of the packing machine 8 are two sub-shafts 62 and 63 with side walls 64 and 66 or 67 and 68 likewise diverging in the longitudinal direction of the filter cigarettes 2. The sub-shafts 62 and 63 branch off at the junction 6 from the conveyor shaft 61. For dividing the flow of filter cigarettes conveyed down the conveyor shaft 61 In two partial flows further conveyed in the partial shafts 62 and 63, a stationary, roof-shaped one is used Deflection means 69 formed by the side walls 66 and 67 of the sub-wells 62 and 63, respectively. Operation of the device according to Figures 1 to 3: Filter cigarettes 2 are from the dispensing drum 41 of The filter attachment machine 42 is brought between the conveyor belts 33 and 34 and conveyed upwards to the feeder 3. the Filter cigarettes 2 are taken over by the drum 26 and the pair of conveyor belts 27 and straightened out of their upward Conveying direction out in a downwards to the collecting container 1 to directed conveying direction. Normally the production output of the filter attachment machine 42 is on the processing power of the packing machine 8 is matched,

so that the filter cigarettes 2 are conveyed into the collecting container 1 and get out of this again through the outlet 18 into the conveying shaft 61. Processes the Packing machine 8, however, fewer filter cigarettes 2 per unit of time than is produced by the filter attachment machine 42 more filter cigarettes 2 are conveyed into the collecting container 1 from the feeder 3 per unit of time as filter cigarettes leave this through the outlet 18. Because the feed 3 in the area of the junction 47 in introduced the collecting container 1 with a conveying device which has a component in the direction of the end wall 19 designed as a pressure-sensitive button 17, the end wall 19 is pressed into its drawn out position by the increasing pressure in the collecting container 1, wherein the limit switch 52 closes its contact and the floor tape 13 with the end wall 21 of the Rotating field magnet 16 is driven in such a way that it extends from the end wall 19 in the sense of increasing the storage volume of the collecting container 1 moves. As a result, the pressure within the collecting container 1 decreases and the end wall returns to its hullage, making contact of the limit switch 52 opens again and the power supply for the rotating field magnet 16 is interrupted. This The work cycle continues until the packing machine 8 runs at its normal output again, or else if the disturbance persists for a long time, the end wall 21 attached to the floor band 13 becomes the end switch actuated, whereby the function of the limit switch 52 is suppressed and the filter attachment machine 42 is stopped will. If the malfunction in the packing machine 8 is eliminated, the filter attachment machine 42 remains out of operation for the time being. whereby as a result of the removal of filter cigarettes 2 from the collecting container 1 through the outlet 18, the pressure decreases in the collecting container 1 and the end wall 19 in the The dot-dashed position pivots.

Between the delivery end of the conveyor belt 279 and the receiving station 272, a further horizontally running conveyor belt 286 is provided, which is guided over rollers 287 and 288 is. a belt drive 289 firmly connects the roller 287, which serves as a drive roller for the conveyor belt 286 the drive, not shown, of the packing machine 274. Two buttons, which are designed as photocells 291 and 292 are used to monitor the flow of rod-shaped articles (e.g. filter cigarettes) through the viewing section on conveyor belts 279 and 286. Bin control relay 293 can be excited by photocell 291 and is used for control a pole-changing electric motor 296.

The motor 296 is connected to the drive roller 277 for the conveyor belt 279 via the belt drive 281 and is used for Drive the same with at least two speeds.

A time relay 294 can be excited by the photocell 292 and works together with the control relay in the same way as in the mode of operation of the arrangement described below will be explained in more detail.

The mode of operation of the arrangement according to FIG. 5 "insofar as it has not already been explained with reference to the aforementioned FIG. 4 is as follows:

A flow of filter cigarettes moves on conveyor belts 279 and 286 to receiving station 272 and passes through the monitoring area of the two photocells

291 and 292. If a fault occurs in the packing machine 274, which leads to a standstill of the same, then the conveyor belt 286 also stops. In the transition zone between the Conveyor belts 279 and 286 - in the area of the photocells 291 and

292 - This causes a jam in the flow rate. As a result, both photocells 291 and 292 are covered. In this case the photocell 291 triggers the control relay

293 for interrupting the power supply to the motor 296, and

- 18 -

Sfw- .: Flow magazine sack buffer summary - A 1206 Bergedorf, April 12, 1973

the conveyor belt 279 stops. The packing machine is coming in G-ang again, the conveyor belt 286 also conveys cigarettes again, and the photocell 291 becomes free again. In in this case the control relay 293 is energized. The control relay 293 is a mutually lockable double relay (two windings) for two different speeds of the motor 296. With free photo cell 291 "and darkened photo cell 292 only the winding of the relay 293 is energized, which sets the motor 296 in motion at the lower speed puts. The cigarette feed stream is therefore now slowly moved to the conveyor belt 286.

If the packing machine 274 processes more cigarettes than are fed in by the conveyor belt 279, then the Photocell 292 free and excites the other winding of the control relay 293 which drives the motor 296 to its higher speed caused. This causes the influx of cigarettes. to the conveyor belt 286 increased. If the photocell is covered again as a result of an excess of cigarettes conveyed The time relay 294 is energized by the photocell 292. After a presettable time has elapsed, the timing relay 294 energizes that Winding of the control relay 293 "which causes the motor to its lower speed, that of a conveyor belt" speed of the conveyor belt 279 corresponds to the mif the Cigarette consumption of the normally working packing machine matches. The time relay 294 goes back to its rest position, while the control relay 293 by self-holding contacts remains in its last position. If the packing machine 274 fails again, this is repeated the game described. Such switching arrangements. are well known and are therefore not included here in Described individually. ■

The mode of operation according to FIG. 6 is in Principle the same as in FIG. 5 Only instead of the conveyor belt 286 in FIG. 5 is a roller conveyor provided, which is composed of several driven rollers 397. The rollers 397 are at a radial distance arranged to each other so that cigarettes can pass between them. The drive of the rollers 397 can both from the packing machine drive as well as from a separate drive.

In FIG. 7, parts that correspond to those of FIGS. 1 and 2 are given the same reference numbers, increased by number 400, designated and not explained again. Was in the feed shown in Figures 1 and 2 to ' guided introduction of the filter cigarettes into the collecting container on the designed as a pressure-sensitive button End wall arranged a pivotable guide, so in this embodiment is a pivotable guide in the form of a Loop 501 made of elastic material (e.g. plastic) is arranged on a stationary holder 502 below the drum 426. The filter cigarettes 402 are held between this loop 501 and a stationary wall 503, wherein the loop 501 is pressed towards its holder 502 as the cigarette level rises, which is indicated by dash-dotted lines in the drawing is indicated.

To support the filling of the storage space 401, a roller 504 is provided, which in the same conveying direction and approximately can be driven at a peripheral speed corresponding to the movement of the floor belt 413. This can

the storage space 401 can be made higher, and the pressure on the end wall 419 is reduced. The end wall 419 has a protruding nose 506 at the level of the roller 504. This separates the storage space 401 and the filling space

507 achieved by being between the roller 504 and the End wall 419 adjusts compression in the cigarette assembly. Also, the end wall 419 is not just about the axis 422 mounted so as to be pivotable, but also pivotable in a hinge 505 perpendicular to this. The hinge 505 is on the one hand on a guide attached to the end wall 419

508 and on the other hand on a guide 511 fastened to a holder 509 which sits on the axis 422 in a longitudinally axial The direction of the filter cigarettes 402 is displaceable. Filter cigarettes have different hardnesses at the end of the fire and at the filter end, the hinged end wall 419 adapting to this different hardness can. The adjustment of the hinge 503 in the direction of of the cigarette axes enables optimal adaptation to different cigarette lengths and cigarette hardnesses even during operation. Together with the nose 506 of the end wall 419 and the roller 504 thus becomes a parallel one Alignment of the filter cigarettes 402 in the filling space 507 regardless of the inclination of the filter cigarettes 402 in the Storage space 401 guaranteed. The driven roller 504 also ensures that when driving out of the storage space 401 A sufficient number of cigarettes remain in the filling space 507.

The limit switches of the embodiment of Figures 1 and 2 were in this embodiment by proximity switches 512 and 513 replaced, whereby the paths of the wall 419 kept smaller and a higher frequency of response was achieved, which resulted in a calming of the cigarette movements in the storage space 401 and in the filling space 507 and thus to one

has carried out gentler cigarette treatment. In the course of the conveying path of the filter cigarettes 402 on the drum 426, a reflection light barrier 514 is arranged, in the event of a backlog of filter cigarettes 402 as a result emits a signal to switch off the upstream machine in the event of a fault in the feed area.

An advantage of the invention is that with this device, relatively high stacks of cigarettes in a sack buffer can be saved due to the arrangement of the button and the cigarette feeder a sensitive, fast-reacting and therefore cigarette-friendly control of the bag buffer as well as trouble-free operation of the Storage device is made possible.

Another advantage of the invention is that due to the inclined out of the perpendicular guide of the Conveying shaft and the diverging side walls of the shafts in the longitudinal direction of the article, the contact pressure of the Article against the deflector is low and especially filter cigarettes in the area of the deflector is not can lay across, which prevents interference in this area.

A further advantage of the invention is that also with a direct coupling of the production machine and further processing machine a visual inspection of the articles is carried out immediately before they are further processed can be.
