Definitions
- the invention relates to a manufacturing machine for manufacturing rod-shaped products from an endless strand of a strip bonded to form a tube with the features of the preamble of claim 1 and a method for manufacturing rod-shaped products with a manufacturing machine with the features of the preamble of claim 12 and a Product according to claim 15 cut from an endless strand of an endless strip bonded to form a tube.
- Such a strip can be, for example, a paper or wrapping strip, such as is used, for example, in devices for the manufacture of products in the tobacco-processing industry, such as, for example, cigarettes or filter segments.
- the paper strip or wrapping strip is fed to the device in the form of an endless strip, e.g. provided with a line of glue on one of the edges by means of a device and then folded into a tube in a shaping section and finally, for example, glued at the edges to form an endless tubular strand.
- an endless strip of filter material or tobacco fibers can be placed before the shaping process, which then fills the cavity in the tubular strand.
- Another application is the production of drinking straws in which somewhat stiffer strips are deliberately used, which are made of a food-compatible material, and after the shaping process and gluing, tubular drinking straws are cut in a predetermined length by means of a cutting device. ge are cut off.
- tubular segments of a predetermined length can be cut from a tubular endless strand.
- a device used in such a higher-level manufacturing machine for applying a glue line to an endless strip is known, for example, from DE 10 2014 213 858 B3.
- the device for applying the glue line comprises a nozzle held on the device, by means of which a glue line is applied to a roller which is driven to rotate in a rotational movement and which in turn applies or rubs the glue line onto one of the edges of the strip.
- the glue line can only be on one edge of the strip in a width of 1 or 2 mm or even over the entire area, over the entire width of the strip, for example in a width of 5 to 35 mm or 5 to 28 mm be worn.
- the nozzle is arranged eccentrically to the axis of rotation of the roller at a distance of 0.05 to 0.15 mm.
- a pent-up glue reservoir forms at the opening of the nozzle in a space to the roller, the volume of which can be changed via the distance between the nozzle, the volume flow of the emerging glue and the speed of the roller, i.e. the removal of the glue.
- the advantage of this solution can be seen in the fact that the glue is rubbed into a glue track of constant width and thickness on the roller before it is applied to the strip, so that the glue track applied to the strip has a significantly improved quality in terms of the thickness and width to be maintained .
- the glue track After the glue track has been applied, the glue track dries out automatically, with drying being additionally supported or ensured by a heat source directed towards the glue track or the subsequently produced adhesive seam of the fixed tubular strand or a drying section to be run through until the products are finally produced be cut by means of the cutting device from the endless strand in a predetermined length.
- the cutting device Since the products are cut from an endless strand, and the glue line is also applied to the strip as an endless glue line and glued to form an endless glued seam, the cutting device inevitably cuts through the glued seam when the products are cut from the endless strand. This can lead to smaller particles of glue mixed with particles from the grinding of the knife or dust from the environment sticking to the knife of the cutting device when the strand is cut, especially if the glue seam is not yet completely dry. These adhering particles can subsequently worsen the quality of the cut surface of the products or generally contaminate the products to be cut subsequently and are also referred to as so-called “black particles”.
- the invention is based on the object of providing a manufacturing machine and a method which enable a cut of the products while avoiding the disadvantages explained at the beginning, with an improved quality of the products. It is also an object of the invention to provide a rod-shaped product with an improved quality that is cut from an endless strand of an endless strip bonded to form a tube to create the interface.
- the device for applying the glue track in the manufacturing machine is formed by a device which applies the glue intermittently with the formation of regularly spaced glue-free sections, and a sensor device is provided which on the endless strip or the endless strand is directed and, depending on the passing of a glue-free section, generates a signal, and the device for applying the glue is set up to adjust and / or change the length of the glue-free sections in the longitudinal direction of the glue track .
- the length of the glue-free sections in the longitudinal direction of the glue track can be set in a targeted manner so that they have a predetermined, optimized length.
- the arrangement of the glue-free sections i.e. the distances between the glue-free sections, can be set in such a way that the cutting device cuts the rod-shaped products from the endless strand by cutting through the glue-free sections.
- This compliance with the length and in particular the position of the sections with respect to one another can then can be monitored by the signal of the sensor device, wherein the signal can be used in addition to an adjustment of the arrangement and the length of the glue-free sections when starting up the device.
- the signal of the sensor device can be displayed or perceived during manual adjustment of the device for applying the glue track, for example by means of a suitable display device, so that an operator can then adjust the length and position of the glue-free sections in the glue track taking into account the Can make the Sen sor coupled signal.
- the proposed intermittent glue application has the advantage of an improved order pattern of the glue track in general, since the glue at the outlet opening of the nozzles is regularly and completely removed by interrupting the glue supply at regular time intervals. As a result, the formation of glue protrusions, which is disadvantageous for the application pattern of the glue track, can be prevented at the outlet opening.
- the device for applying the glue has a control for setting and / or changing the duration of the interruption, ie the timing of the glue application.
- the timing can be controlled so that the glue-free sections have a predetermined length, and in addition the timing can be controlled so that the glue-free sections each have a distance from one another corresponding to the length of the products to be cut. This ensures that the cutting device, which is in the cutting frequency is also set to the length of the products to be cut, cuts through the glue-free sections when cutting and is thus not contaminated by the glue.
- the length and / or position of the glue-free sections can alternatively or additionally be changed in that the device for applying the glue has a nozzle whose distance from the glue track to be applied can be changed. Due to the variable distance between the nozzle, the application pattern of the glue track on the strip can be actively changed.
- the nozzle or, in the case of several nozzles, all or some of the nozzles can be separated from a glue supply and reconnected to the glue supply after a predeterminable time interval.
- the device for applying the glue can in particular have a rotationally driven roller to which the nozzle of the device applies the glue track and which applies the glue track further to the edge of the endless strip.
- the glue line is thus not applied directly to the strip by the nozzle, but first on a roller, which then applies the glue line to the strip in an improved application pattern.
- This enables a glue track on the strip which does not have any specks of glue, which can occur when the glue track is applied directly to the strip due to a residual portion of the glue adhering to the nozzle.
- the glue is first rubbed by the proposed solution on the roller to form a line of glue of constant width and thickness and only then applied from the roller to the strip.
- this distance is here the distance between the outlet opening of the nozzle and the glue track applied to the roller, while the distance or the Contact of the roller to the strip is constant. Since the geometry of the glue line applied to the roller also corresponds to the geometry of the glue line applied to the strip, in this case both the application image of the glue line on the roller and the application image of the glue line can be changed by changing the distance between the nozzle and the roller changed on the strip. Since the distance between the roller and the strip or the contact is not changed, the distance between the nozzle and the strip is also indirectly changed here. The roller is practically just an "intermediate part" for transferring the glue emerging from the nozzle to the strip, to which the distance of the nozzle is changed.
- the nozzle can preferably have an edge section which limits the outlet opening and projects in the direction of the roller and which is arranged on the edge of the outlet opening which is arranged downstream in relation to the direction of rotation of the roller.
- the protruding edge section on the downstream edge of the outlet opening deliberately reduces the gap between the edge of the outlet opening and the roller through which the glue emerging from the nozzle is transported away, so that the glue at the outlet opening deliberately becomes a glue reservoir is dammed up, from which the glue is then transported away via the roller.
- the glue reservoir forms a supply from which the glue is further applied to the roller, even if the glue supply through the nozzle is stopped or interrupted.
- the formation of the glue reservoir can alternatively or additionally also be supported in that the nozzle with the center of the outlet opening is arranged eccentrically to the axis of rotation of the roller counter to the direction of rotation of the roller. Due to the eccentricity of the nozzle, the distance between the roller and the downstream edge of the outlet opening is reduced to the direction of rotation of the roller. At the same time, the free space between the roller and the outlet opening, in which the glue reservoir is dammed up, and which is arranged in relation to the direction of rotation upstream to the narrow point between the downstream edge of the outlet opening and the roller, is enlarged.
- the roller be driven in opposite directions in relation to a transport direction of the endless strip.
- the roller is thus driven in such a way that the strip is guided past the roller against the rotational movement of the roller, so that the relative speed of the strip to the roller is the sum of the transport speed of the strip and the circumferential speed of the surface of the roller with the glue track arranged on it results. Due to this increased relative speed of the strip to the roller, the glue is rubbed on the strip at a higher speed. As a result, the glue line on the roller is applied to the strip to form an even finer and, in particular, special thinner glue line.
- the glue have a viscosity of greater than 230 mPas and in particular greater than 1000 mPas.
- the glue is therefore a highly viscous glue and can therefore be Very high dimensional accuracy can be applied as a glue line on the strip. In this way, in particular, spills or other quality disadvantages in the uniformity of the distribution of the glue can be avoided.
- the use of highly viscous glues has the advantage that the glue track hardens or dries faster after gluing the edges of the strip, so that the drying path to be followed by the endless strand after gluing can be made shorter or additional measures for hardening the glued seam can be measured more easily or can even be omitted.
- glue-free sections of, for example, 4 mm and less can be achieved by applying the glue intermittently and also forming a glue reservoir from which the glue can be used for one more time after the glue supply is interrupted to shorten the glue-free section short distance is applied.
- the sensor device is arranged between the format section and the cutting device.
- the sensor device is thus directed towards the shape-fixed endless strand upstream of the cutting device in relation to the transport direction of the strand. Since the sensor device as well as the cutting device are stationary on the Fierstellmaschine, the cutting device is also in a fixed spatial assignment to the sensor device, so that from the signal of the sensor device, taking into account the transport speed of the strand, it can also be determined when the glue-free sections the glued seam pass through the cutting device, or whether the knife of the cutting device that cuts through the strand also cuts through the glue-free sections of the glued seam. It is particularly advantageous that the Strand after the gluing of the glue line in the format section is no longer changed apart from the transport in the form.
- the sensor device in this case is a floch frequency sensor device, which can detect the glue-free sections also through the position of the tubular strand covering the adhesive seam to the outside.
- the sensor device is arranged between the device for applying the glue line and the format section.
- a method for operating a manufacturing machine according to one of claims 1 to 11 is proposed, in which the device for applying the glue track is controlled for setting and / or for changing the length of the glue-free sections as a function of the signal from the sensor device .
- the advantage of this solution is that the signal from the sensor device can also be used for an automated or semi-automated regulation or control of the manufacturing machine, in which the device for applying the glue line to adjust and / or change the length of the glue-free sections is controlled as a function of the signal from the sensor device.
- the alignment and length of the glue-free sections in the glue track can also be checked online, i.e. during the Operation of the manufacturing machine can be changed without manual intervention to carry out the setting is required.
- the adjustment can be triggered automatically if the sensor device detects a deviation of the actual value from the target value which exceeds a predetermined tolerance value. Alternatively, the adjustment can also be triggered manually but carried out automatically.
- Setting and / or changing the length of the glue-free sections can preferably be done by setting and / or changing the duration of the interruption of the glue application and / or by setting and / or changing the distance of the device for applying the glue track the strip fen be effected.
- the manufacturing machine is designed according to one of claims 4 to 8 or according to one of claims 9 to 11 in relation to one of claims 4 to 8, and setting and / or changing the length of the glue-free Sections is controlled by adjusting and / or changing the speed of the roller.
- the process can be further improved in terms of production capacity by transporting the strip at a transport speed of more than 100 m / min, without this having any disadvantages for the quality of the interfaces and the adhesive seam.
- a rod-shaped product cut from an endless strand of an endless strip bonded to form a tube is proposed, the strip with an adhesive seam interrupted by glue-free sections to the tube is glued, and the product is cut from the strand by a cut through one of the glue-free sections.
- the products have a higher quality interface, since the interface is not contaminated by glue particles and abrasive or dust particles adhering to them due to the cut through the glue-free sections.
- the glue-free sections should be as short as possible so that the product is glued over the longest possible length.
- the glue-free sections are subdivided by the cut, so that the remaining length of the glue-free sections at the ends of the products is only ever formed by a section of the original glue-free section, that is, it is significantly shorter.
- the adhesive seam can be formed from a highly viscous glue with a viscosity of more than 230 mPas and preferably more than 1000 mPas, whereby a very strong adhesive seam with a very high degree of dimensional accuracy can be achieved, especially in the area of the glue-free sections.
- the product is formed from a food compatible material. This makes it possible to use the rod-shaped products for suction, storage and transport of food in general.
- the products can be used as drinking straws or as packaging for food.
- FIG. 1 is a device according to the invention in a schematic presen- tation
- Fig. 3 is an enlarged sectional view of the device for applying the glue.
- FIG. 1 a schematic representation of the Fierstellmaschine 1 according to the invention can be seen, to which an endless strip 2 is fed, for example in the form of a paper strip.
- the strip 2 is led past a device 15 for applying a glue track 13, which can only be recognized in Figures 2 and 3.
- the strip 2 is introduced into a Formatab section 10, in which the edges of the strip 2 beat up, superimposed and finally connected to each other via the glue line 13 to form a glued seam and fixed to form an endless tubular strand 9.
- the format section 10 is followed by a drying section 11, which can be provided with additional drying units, for example heat sources.
- the drying section 11 is designed, depending on the nature of the glue and the transport speed of the strand 9, so that the glue seam after exiting the drying section 11 is dried to such an extent that it can then no longer come off.
- the fixed, tubular strand is guided past a cutting device 4, which cuts rod-shaped products 3 from the strand 9 in a predetermined length.
- the cutting device 4 comprises a rotating knife carrier with one or more radially protruding knives 8, which through the Cut the rotary movement of the knife carrier through the strand 9 at defined time intervals and thereby cut the products 3 from the strand 9 in a predetermined length, taking into account the transport speed of the strand 9.
- Such pro ducts 3 can be, for example, drinking straws, prefabricated products 3 of the tobacco processing industry, prefabricated products 3 of “Heat Not Burn” products or else electronic cigarette products.
- the manufacturing machine 1 corresponds to a manufacturing machine 1 known in the prior art.
- the manufacturing machine 1 differs from the prior art in that the device 15 for applying the glue line 13 is designed as an intermittent application device, and that in addition at least one sensor device 7 is provided, which, as will be explained in more detail below, is directed to the strip 2 or to the strand 9.
- the strip 2 with the device 15 for applying the glue line 13 can be seen from above.
- the device 15 applies the glue track 13 intermittently, that is to say with the formation of glue-free sections 14 of a predetermined length, onto the edge of the strip 2.
- the strip 2 is folded over and glued to the tubular strand 9, the glue track 13 with the glue-free sections 14 connecting the two edges of the strip 2 in the tubular strand 9 to one another by a regularly interrupted adhesive seam.
- the device 15 can apply the glue track 13 in different widths up to a full-surface glue application on the strip 2, depending on how the gluing of the strip 2 to the tubular strand 9 is to be implemented. You can also use several strips 2 are glued in several layers to form a strand 9. Furthermore, a sensor device 7 is provided, which is either arranged between the format section 10 and the device 15 for applying the glue track 13 and is directed at the edge of the strip 2 provided with the glue track 13, or alternatively arranged between the format section 10 and the cutting device 4 and is directed to the adhesive seam in the strand 9.
- the sensor device 7 is designed in such a way that it generates a signal that is dependent on the passage of a glue-free section 14 in the glue track 13 or in the glue seam, which signal enables a conclusion to be drawn about the length of the glue-free section 14. Furthermore, the sensor device 7 is in a fixed spatial association with the cutting device 4, so that, taking into account the transport speed of the strip 2 or the strand 9, it is also possible to draw a conclusion as to when the detected glue-free sections 14 pass the cutting device 4.
- a control unit 12 is also provided on the Fierstellmaschine 1, to which the signals from the sensor device 7 are fed.
- the control unit 12 is additionally connected to the device 15 for applying the glue line 13 and the cutting device 4 and a drive device (not shown) for the strip 2 or the strand 9 in terms of signaling.
- the control unit 12 can furthermore comprise a display device and an input unit, which enable the display of the determined parameters and the input of corresponding control commands.
- the operator can set the Fierstellmaschine 1 in a one-time or regularly repeated adjustment process.
- the operator can use the sensor device 7 Averaged signals, which are displayed by an evaluation taking into account the transport speed, recognize the point in time at which the glue-free sections 14 are passed on the cutting device 4.
- the operator then sets the manufacturing machine 1 in such a way that the glue-free sections 14 pass the cutting device 4 precisely when the cutting device 4 cuts through the strand 9 with the knife 8.
- the setting can also take place online in a fully automated control method, that is, during operation of the manufacturing machine 1, so that manual intervention or manual control to initiate the adjustment process is not required.
- the adjustment of the length and position of the glue-free sections 14 in the glue track 13 is carried out by controlling the device 15, as will be explained in more detail below.
- FIG. 3 a section through the device 15 for applying the glue line 13 with the strip 2 guided past it can be seen in an enlarged illustration.
- the device 15 comprises a nozzle 5 with an outlet opening 17, from which the glue exits, and a roller 6 driven in a rotary motion in the direction of the arrow to which the glue emerging from the outlet opening 17 is applied in the form of a glue track 13.
- the se glue track 13 is then applied or rubbed in by the roller 6 on the edge of the Strei fens 2.
- the roller 6 is driven counterclockwise in the illustration, while the strip 2 is moved vertically downwards. This results in opposite movements of the strip 2 and the roller 6 at the right edge of the roller, i.e. at the edge of the roller 6 along which the strip 2 is guided thus results from the sum of the transport speed of the fens 2 and the peripheral speed of the roller 6, and the glue is applied to the strip 2 at a correspondingly increased relative speed.
- the intermittent device 15 can be controlled in such a way that the duration of the interruption of the glue supply as well as the beginning and the end of the interruption of the glue supply are changed, while the remaining parameters remain constant .
- the nozzle 5 is arranged with the center of the outlet opening 17 by the amount E upstream of the rotational movement of the opposite circumferential surface of the roller 6, ie opposite to the transport direction of the strip 2 eccentrically to the axis of rotation of the roller 6 ver sets. Furthermore, the nozzle 5 has at its lower in the presen- tation, so in relation to the circumferential movement of the roller 6 downstream edge 18 to a in the direction of the roller 6 protruding edge portion 16, through which the distance A between the edge 18 of the outlet opening 17 and the roller 6 is reduced ver and a bottleneck is formed. Through this narrow point, the glue is applied in a glue track 13 with a correspondingly reduced thickness to the circumferential surface of the roller 6 and transported away from the roller 6 before it is applied to the strip 2 as a glue track 13.
- glue emerging from the outlet opening 17 is dammed up to form a glue reservoir 19 before it is transported away through the constriction.
- This deliberately formed glue reservoir 19 has the advantage that the length of the Glue-free sections 14, especially when using highly viscous glues with a viscosity of 230 mPas and in particular 1000 mPas and more, can be reduced to a length of 4 mm and less, which would otherwise be the case at the high transport speed of the strip 2 with such a high viscosity Glue would not be possible. This is done in that the glue reservoir 19 is initially built up consciously during the glue supply.
- the glue is then further applied from the glue reservoir 19 onto the roller 6 and above it onto the strip 2 until the glue reservoir 19 is also emptied. Only then does the glue application end on the strip 2, so that the temporal and local start of the glue-free section 14 on the strip 2 can be deliberately further delayed compared to the interruption of the glue supply. This time delay depends in turn on the volume of the glue reservoir 19, which in turn can be changed by reducing or increasing the distance A. Since the roller 6 is stationary with its axis of rotation and the strip 2 is arranged at a constant distance or contact with the strip, there is also a change in the distance between the nozzle 5 and the strip 2. If the glue track 13 is applied directly to the strip 2 from the nozzle 5, the beginning and the length of the glue-free sections 14 can also be achieved in the same way by the formation and change of the glue reservoir 19, which is located directly between the nozzle 5 and the Strip 2 is formed.
- the volume of the glue reservoir 19 and thus the time delay of the interruption of the glue application can be steered by the glue reservoir 19 being dammed up to a larger volume by reducing the distance A.
- the volume of the glue reservoir 19 as well as also the glue application directly and thus the length of the glue-free From sections 14 by changing the speed of the roller 6 ge can be controlled.
- Controlling the length of the glue-free sections 14 by changing the distance A from the nozzle 5 to the roller 6 has the particular advantage that it reduces the length of the glue-free sections 14 to lengths of less than 4 mm, in particular to 2-3 mm can be, which is not possible solely by controlling the temporal interruption due to the inertia of the locking mechanism in the intermittent device 15 for mechanical reasons at the high transport speeds of the strip of 100 m / min and more in particular of more than 400 m / min .
- An application of glue via the roller 6 shown has the additional advantage that the nozzle 5 does not come into contact with the strip 2 and is therefore not subject to closure. This is particularly advantageous because the nozzle 5 is a comparatively expensive component, so that the maintenance costs of the manufacturing machine 1 can be reduced, since the required change intervals for the nozzle 5 can be considerably extended.
- the glue application on the roller 6 also allows a clean glue application on very porous papers, and it can be avoided in particular the unwanted glue bleeding through the paper ver.
- the glue is applied from the nozzle 5 to the roller 6 in a contactless manner, so that any amount of glue is applied to the roller 6 both vertically and horizontally and finally further applied from the roller 6 to the strip 2 can be.
- an amount of glue of 150 g / 500 m can be applied to the strip 2, which is not possible by applying glue directly to the strip 2 via the nozzle 5 in the desired quality.
- the application of the glue track 13 with the glue-free sections 14 counteracts the tendency for the formation of glue protrusions at the nozzle 5, since the nozzle 5 due to the regular interruption of the glue supply at regular time intervals by the “idling” of the glue reservoir 19 at its outlet opening is practically “cleaned".
- the glue track 13 can be made very narrow and applied to one of the edges, so that the products 3 are only glued by a very narrow adhesive seam in a thin edge section of the overlapping edges. If a firmer glue seam or a stiffer product 3 is to be produced, the glue track 13 can also be applied wider up to the entire width, i.e. in a full-surface application, and the products 3 can in this case by superimposing and gluing the edges with wider ones Edge sections to a higher Formstabili ity can be fixed with a smaller diameter.
