Definitions
- the invention is in the field of mechanical engineering and relates to a manufacturing plant for the production of bulk goods, in particular for the production of cotton swabs.
- the main problem is the susceptibility of a machine, which is operated so to speak constantly at the limit of the maximum possible speed.
- the example of the cotton swab production mentioned above shows that it operates at a rate of up to 162 ⁇ 00 sticks per hour, 2'700 sticks per minute (162 ⁇ 00 / 3600) or 45 sticks per second, around the clock , 7 days a week.
- the primary carrier chain consists of a revolving chain, also called conveying or transport chain, with carriers attached thereto for receiving the individually supplied rods, which are provided in the process at their ends with cotton and discharged from the carrier again become.
- the primary carrier chain is subjected to quite high loads, load by weight to be transported, stress by strain, vibration by vibration, stress by friction and stress by general deformation forces.
- Object of the present invention is therefore to propose a manufacturing plant for the production of bulk goods, in particular cotton swabs, which is durable, low in wear and in particular less prone to failure.
- the primary carrier chain is to be less loaded while maintaining production capacity and therefore be subjected to less wear.
- the manufacturing plant includes a feed side for the raw material, a processing unit for the same, and preferably a lead-out side for the products made from the raw material.
- the manufacturing plant is characterized in that it has on the supply side means for the optional multiplication of the feed of the raw material.
- Simplified means that in the feed of the raw material to the processing unit per unit length of the feed line number or weight more raw material is contained.
- the feed side also called feed device, preferably contains a primary carrier chain for feeding a first raw material, in particular empty sticks.
- the feed rate of the first raw material refers to the speed of the primary carrier chain.
- the primary carrier chain is preferably formed circumferentially.
- the production plant or the feed side preferably contains a device in the form of a feed unit for feeding a second raw material, in particular a cotton wool tape or a wadding cord.
- the feed rate of the second raw material thus refers to the speed at which the cotton wool tape or wadding cord is fed to the feed side.
- the feed unit is designed to transfer cotton portions from the wadding cord fed to the feed unit to the rods carried on the carriers along the conveying path of the primary carrier chain, in particular its ends.
- the feed unit preferably also contains means, such as tear-off or Anreissrollen for portioning the cotton.
- the said feed unit is also called metering unit.
- the manufacturing plant also contains on the feed side a processing unit for producing products, in particular cotton swabs, by processing the supplied raw material, in particular the supplied first and second raw material.
- the processing unit of the production facility has means by means of which the second raw material discharged from the supply unit to the ends of the rods is molded onto the latter.
- the production plant preferably also contains a removal side, also called a removal device, preferably with a secondary carrier chain for the removal of the products.
- the removal rate of the products relates in particular to the speed of the secondary carrier chain.
- the production plant preferably contains a transfer unit, via which the products, in particular the cotton swabs, are transferred from the carriers of the primary carrier chain to carriers of the secondary carrier chain.
- the components of the transfer unit are preferably part of the supply and Weggarseite.
- the production facility now has on the supply side means for selectively increasing the supply of the raw material, in particular of the first and / or second raw material.
- the multiplication of the feed of the first raw material on the feed side can be achieved, for example, by reducing the distance of the first raw material present in the form of blanks, in particular rods, and supplied by a carrier chain of the processing unit.
- the blanks are held on carriers, which in turn are attached to the carrier chain.
- the distance between the blanks can be reduced, for example, by providing a plurality of receptacles per carrier, in particular two receptacles for accommodating a plurality of blanks, in particular two blanks, instead of the usual receptacle.
- the length of the carrier in the direction of rotation of the carrier chain can also be reduced, in particular halved. So z. B. the carrier still have only a single recording for a blank. Due to the reduction of the carrier length, the number of blank per length portion of the carrier chain is still increased, z. B. doubled.
- support for the blanks may be provided in which the holding distance between the blanks of a standard size of z. B. two inches to half of z. B. shortened one inch. As a result, twice the number of blanks can be accommodated per length of the chain.
- the feed rate of the blanks to the processing unit as well Accordingly, the output rate of the products following the processing of the raw materials at reduced feed rate of the blanks or the carrier chain can be maintained.
- the manufacturing plant at the feed side at least a first device, also called feeder module, for supplying the first raw material, i. the blanks or the rods, to the carrier of the carrier chain.
- the device may, for example, contain a storage cassette which receives the blanks and delivers them in a timed manner to the carriers of the carrier chain.
- the production facility at the feed side preferably contains at least one second device, also called feeder module or feeder unit, for feeding a second raw material, in particular a wadding cord.
- the second device corresponds z. B. the previously mentioned feed unit for the Watteschnur.
- the second raw material is preferably supplied to the processing unit.
- the processing unit is expediently arranged along the carrier chain, via which the first raw material is fed to the processing unit.
- first devices can alternately equip the carriers with blanks.
- the second devices may also feed the processing units alternately with the wadding cord.
- the first and second devices can this z. B. in each case be arranged along the carrier chain one behind the other. Accordingly, the plurality of first or second devices, in particular for the alternate placement of the carrier with rods, selectively switchable.
- the plurality of first and second devices can respectively fully or partially load the carriers.
- a wear-optimized production speed can be set by mass-ie weight reduction of the feed per blank .
- Mass reduction of the feed per blank means in particular the reduction of the moving weight of the feed, in particular the primary carrier chain incl. Carrier, per blank.
- the mass reduction is achieved by the carriers are made in lightweight.
- An improvement would, as mentioned, bring about a reduction in the weight of the carriers which are today made of metal. This could be done for example by an embodiment of this carrier in tough plastic or other lightweight and wear-resistant material, such as aluminum.
- the carrier can thus z.
- Example of metal in particular a ferrous metal, such as steel or aluminum.
- the carriers are preferably made of a plastic, such as polypropylene.
- the plastic preferably has a high impact resistance.
- the plastic is particularly preferably fiber-reinforced, in particular glass fiber reinforced.
- plastic carriers has the advantage that the weight of the primary carrier chain can be massively reduced. As a result, drive energy can also be saved. In addition, the weight-reduced primary carrier chain can be better accelerated and decelerated, whereby the wear is significantly reduced. Furthermore, such a primary carrier chain operates much quieter because less metal-to-metal noise is generated. As an alternative or in addition to the preceding measure, the reduction in mass can also be achieved by the carrier chain carrying more blank per length section, as described above, while the chain length remains the same. Likewise, one could arrange for the same length of the carrier receiving sites for several rods, which would also bring a weight reduction per rod.
- the length of the carrier could also be halved, so that transported on the same chain section length instead of one, two rods. This achieves that the same production output (here 162 ⁇ 00 cotton swabs per hour) is achieved at half the chain speed.
- the carrier weight per transported rod can be reduced, which causes a much lower wear and thus a lower susceptibility to interference with the same performance of the circulating primary carrier chain.
- the disturbance reduction of the "cotton feed" unit has not yet been achieved in all aspects because the virtual velocity has remained the same when the individual sticks pass by.
- the dwell time of a rod under the cotton wool is twice as long compared to the top speed of wear, so that a reduction of the disturbance is also achieved here.
- Another aspect of the invention therefore, inter alia, also relates to the reduction of the speed of feeding the wadding cord or the cotton wool tape while maintaining the feed rate.
- the wadding cord tends to tear during the production process. This is because the wadding cord has low strength. Namely, the wadding cord contains a multiplicity of fibers which run more or less parallel to one another and which adhere only slightly to one another. The wadding cord has in particular no or virtually no rotation, which would increase the tensile strength. Furthermore, such a wadding cord usually consists of cost-effective fiber material with comparatively short fibers, which is also detrimental to tear strength.
- this problem can be counteracted by increasing the weight of the wadding cord per unit length, for example from 1.4 g / m (weight per length) to 2.8 g / m. This allows the same mass at half speed respectively.
- the number of supplied wadding cords from today 2 to 4, 6 and 8 etc. can be doubled or multiplied.
- a pair of wadding leads to cotton wool only for every second stick. With this measure, the speed of the cotton lace is also halved.
- Cotton cords are usually made from conventional carded belts, which are produced in a card.
- the card is a well-tried device such as z. B. in the processing of fiber material in the textile industry has been used for a very long time.
- the wide sliver is, for. B. in a funnel, to a round sliver, the card sliver, shaped and z. B. stored in loops in a pot.
- the card sliver generally has a band weight of 5 to 20 g / m (grams per meter), in particular of about 8 g / m.
- the weight of the band is now considerably too high for use in the production of cotton swabs.
- the tape or cord weight of the wadding cord fed to the feeder unit is about 1.4 gm.
- the wide card sliver in the longitudinal direction in sub-bands also called Watt cords
- This separation is done for example by means of a targeted air flow.
- this method has the disadvantage that due to the process, the uniform card sliver can not be divided into equally uniform subbands.
- the sub-bands created from the uniform card sliver have rather thick and thin areas. On the one hand, this results in a uniform portioning of the cotton wool being difficult and, moreover, the wadding cord tends to tear at its thin points when it is fed to the feed unit.
- the manufacturing plant includes a drafting system, in which a supplied cotton wool tape is subjected to a delay while reducing the weight of the belt. Warping means pulling apart the fibers of a sliver into a finer ribbon.
- the drafting system is preferably arranged in the process direction in front of the feeding unit for the wadding cord.
- the drafting system is preferably integrated into the manufacturing plant in such a way that, during the production of the cotton swabs, it produces a sliver with delay, which is fed without interruption to the supply unit. If the drafting system operated at a higher output than the feed unit needed for further processing, it may be provided between the feed unit and drafting a buffer in which the excess wadding cord is stored and cached. However, the wadding cord remains advantageously throughout this process, so it is not separated.
- the drafting system is preferably a roller drafting system with at least two rotating pairs of rollers which are spaced apart from one another in terms of conveying, and which rotate at different peripheral speeds.
- the two pairs of rollers form clamping lines for the sliver, on which the sliver is held in each case by clamping.
- the downstream in the process direction of the first pair of rollers second pair of rollers runs at a greater peripheral speed.
- the distance of the clamping lines of the roller pairs in the process direction is now set as a function of the fiber length.
- the nip line is set further than the longest fiber of the warped strip.
- This distance between the roller pairs now defines the so-called default field in which the sliver is warped. While most of the fiber material is retained by the first, slower pair of rollers, some of the fibers pass between the faster rollers of the second pair of rollers. These push them forward, so that a thinning of the sliver arises.
- the lower rollers may be metal cylinders.
- the upper roller may have a flexible cover. Conveniently, the lower rollers are actively driven while the upper rollers are driven indirectly via the lower rollers.
- the drafting system further preferably also includes a loading device with which the upper rollers can be loaded towards the lower rollers.
- the drafting system can now contain more than two pairs of rollers one behind the other in the conveying direction, which define more than one drafting zone.
- the following pair of rollers always runs at a higher peripheral speed than the preceding pair of rollers.
- three pairs of rollers arranged one behind the other can define two default fields. In each of the default fields a partial delay takes place, whereby the partial distortions considered over the drafting system add up to a total delay.
- the drafting rollers can be driven by a separate drive device.
- the drive must be synchronized control technology with the drive of the other moving parts of the system, such as carrier chain or moving, in particular rotating parts of the feed unit for the cotton, etc.
- the drafting rollers are now preferably driven by a central drive, which, for example, also drive the carrier chain and the moving, in particular rotating parts of the feeding unit for the cotton wool.
- the speeds of the drafting rollers are preferably tuned via a mechanical transmission with the speed of other moving parts of the system.
- the invention also relates to a method for operating a manufacturing plant as described above.
- the process is characterized by the fact that the raw material is fed in multiply.
- the plants can now be operated in such a way that the raw material is fed to the feed side for a constant discharge of products at the feed side with a reduced feed rate relative to the removal speed of the products, to the processing unit.
- a further development of the method is characterized by the following steps: - Supplying a cotton wool, in particular from a memory, to the drafting system of the manufacturing plant;
- the cotton tape guided into the drafting system can z. B. have a weight of 5 to 8 g / m.
- the wadding cord released from the drafting system has a weight of 1.4 to 1.5 g / m.
- the total distortion ratio can be 3: 1 to 6: 1, depending on the weight of the initial lap belt.
- the distortion ratio (stretch ratio) in the default zone (stage 1) can be, for example, 1: 1 (no distortion) or 1.15: 1 (very small distortion) to 2: 1, in particular 1: 1 or 1.15: 1 to 1.5: 1
- the draft ratio may be 3: 1 to 4: 1 in the main drafting zone (stage 2), for example.

- the secondary carrier chain in turn rotates deflecting wheels 40 and the running direction is also indicated by arrows in the counterclockwise direction continuously.
- the reference numeral 36 denotes a chain tensioner. This for a general overview, which will be discussed in detail subsequently.

- Figure 1 A shows a section in which one recognizes the feeding unit 50 of the wadding cord, by means of which the supplied cotton is turned on to the rotating in operation about its axis rods.
- FIG. 1B shows a detail in which the secondary carrier chain 32 with the carriers 35 for the cotton swabs 38 hidden by the cotton swabs is recognized.
- the cotton buds are close to each other, the running direction is indicated by an arrow.
- the secondary carrier chain 32 is also associated with hold-down elements 31, which prevent the cotton swabs 38 from jumping out of their holders.
- the detail in Figure IC shows the transfer unit IC with the transition point with the transmission wheel 25, where you can see the incisions 16 'for the support of the cotton swab and cooperating with this carrier wheel 45 with the recesses 46 for receiving the transferred cotton swab.
- the transmission 42 for driving the two carrier chains, the transmission wheel 25 and the carrier wheel 45 How the transfer point works is discussed later on figures.
- the wadding supply unit 50 of the sticks of Figure 1A includes a pair of spout-like guides 53.1 and 53.2, one such guide for each side of the cotton swab.
- the wadding cord threaded therein is fed to a respective pair of pinch rollers 52.1 and 52.2 which, on the one hand, pull off the two wadding cords and, on the other hand, each feed a combing roller pair 55.1 and 55.2.
- the rotational speed of Kammrollenrune 55.1, 55.2 is set so that it subtracts or tears off the supplied from the pairs of pinch rollers 52.1, 52.2 cotton in the selected portion.
- the clamping and Kammrollenpresse be driven via a corresponding gear 51.
- the combed roller pairs 55.1, 55.2 can also form only predetermined breaking points on the wadding cord, which divides the wadding cord into portions.
- the wadding cord is then torn off by the chopsticks passing by and taking the wadding cord portion at the predetermined breaking point.
- the predetermined breaking point can z. B. be a local thinning of the wadding cord by excessive tensile stress.
- the supplied rods which are brought into rotation, are prepared at both ends so that the torn cotton balls or -portions can get caught on it and is wound up in this way.
- the now raw-wound cotton swab is continuously supplied in rotation to the holder 22 for the braking rubber belt in the guide mechanism 21 and formed therein.
- the forming module (not shown) on the guide mechanism is in two over its length divided trough-shaped shapes and pressed together by a lever via a adjustable weight 23 above the guide mechanism.

- the pair of rollers is part of the carrier 15.
- the rod body is braked by, for example, a pressed-on rubber belt (not shown) so that the ends of the rod are constantly rotating with the wad over the entire distance and become full under the pressure of the trough-shaped form Let shape take. If the two wadding cords have to be fed at high speed, it can also lead to disturbances at this point. In contrast, you can proceed by providing in the direction of the rods a second arrangement of a feed unit 50 with pairs guides, pinch rollers and comb rolls and so alternately only every second of the supplied blanks provides with cotton wool.
- Figure 1 C shows the transfer unit 1 C with the transfer point from the primary to the secondary carrier chain. Note the arrangement density on the supports of the two carrier chains. While in the example shown here, the carrier 15 of the primary carrier chain 12 each promote a cotton swab 38, there are on a support of the secondary carrier chain 32 whose four, that is at least four times more, which requires that the two carrier chains run at different speeds. The primary carrier chain 12 thus runs four times faster than the secondary carrier chain 32. Their load is very large at maximum output. If the primary carrier chain 12 is allowed to run, for example, half as fast to relieve it, then only two rods would be deposited per carrier 35 on the secondary carrier chain 32; gaps would form.

- a plant out of the standard mass unit one can with a existing system within the standard mass at the same speed a multiple of cotton swabs transport and thus produce.
- the distance between two to be provided with cotton rods can not be made arbitrarily small as, for example, on the carriers of the secondary carrier chain of the secondary transport unit.
- the minimum distance IVn (min) must not be less than the necessary winding distance for the cotton head.
- L 1 inch
- this distance should be set between L / 3 and L / 4, using only integer denominators. But even the increase to 3 times the production capacity at the same speed is already a considerable result.

- the top rollers 101b, 101c; 102b, 102c; 103b, 103c; 104b, 104c mounted on a loading arm 1 10, over which they are pressed onto the lower rollers 101a, 102a, 103a, 104a.
- the two top rollers 101b, 101c; 102b, 102c; 103b, 103c; 104b, 104c of two parallel roller pairs are each connected to each other via an axis 128 and spaced from each other.
- the top rollers 101b, 101c; 102b, 102c; 103b, 103c; 104b, 104c are rotatably mounted on this axis 128.
- the loading arm 110 now engages between the upper roller pairings 101b, 101c; 102b, 102c; 103b, 103c; 104b, 104c and holds them over their axis 128.
- the loading arm 110 can be pressurized via a pneumatic pressurizing device 120.
- the pressurization can also be done by a mechanical spring.
- the load arm 1 10 can also be opened.
- the loading arm 1 10 is raised by a handle whereby the upper rollers are lifted from the lower rollers.
- the distortion of the cotton wool band 125.1, 125.2 in the drafting system 100 is preferably done in-line in the production process of the cotton swab. Accordingly, the drafting system 100 and in particular their drives control technology and preferably also mechanically integrated into the manufacturing plant.
- the drive of the lower drafting rollers now preferably takes place via a central drive, which also other system components of the manufacturing plant, such. B. drives the primary carrier chain. The drive torque is transmitted via a corresponding transmission gear on the lower rollers.
- a cotton wool band 125.1, 125.2 in the form of a card sliver with a band weight of about 8 g / m is fed to the drafting unit 100.
- the cotton wool band is a 5- to 6-fold delay subjected.
- the wadding 126.1, 126.2 produced from the wadding band 125.1, 125.2 now has a weight of around 1.4 to 1.5 g / m.
- the use of a drafting system in a production plant according to the invention has the following advantages: the drafting arrangement ensures a uniform distortion so that a wadding cord produced from a cotton wool band in a drafting system has a high degree of uniformity;
- the production line supplied card sliver is much more tear-resistant than a thinner wadding string due to its thickness, which in turn sets the susceptibility to failure. Thanks to the integrated drafting system, the conveyor section, in which the tear-prone wadding cord is conveyed between the drafting system and the infeed unit, is considerably shorter;
- card slivers of different band weights can be processed, with only the default parameters in the drafting system having to be adjusted in terms of control technology for producing cotton slivers of the same weight. This provides great flexibility in the procurement of cotton wool from third party producers;
- the drafting system according to the invention allows the procurement of inexpensive but heavier standard card slivers, which are characterized by a standard band weight of 8 to 20 g / m.
- the manufacturing parameters are discussed below.
- the parameters speed of the primary carrier chain V K, the angular velocity of the stick V Red and the speed at which the cotton wool is fed are V w to pay particular attention to in the manufacturing process.
- the following parameters must be taken into account:
- the sticks rest on 2 rolls, so they can be turned. Between the roll forms is placed on the top of a standing rubber belt on which the rods are braked and thereby begin to turn.
- This rubber belt can also be driven; a positive speed means that the rubber belt runs in the direction of travel of the primary carrier chain, a negative one in the opposite chain speed.
- the chain speed is the product of rod spacing ss and machine power P.
- V K s s * P
- the rod speed depends on the rod diameter d, as well as the chain v K and the rubber belt speed VQ.
- a positive value means that the rods rotate in the "winding direction”, ie counterclockwise, and a negative in the "counter-winding direction”, ie clockwise.
- the wadding speed is made up of the machine power P and the heads per meter x s value.
- the frictional forces are by design. They are created by chain guides, cleaning brushes and the resistors in the area of roll forming.
- the torque forces are by design. They are caused by the friction resistance in the sprockets.
- centripetal forces occur when the carrier chain changes direction on the sprockets. Take the centripetal forces
- FG acceleration forces The acceleration forces occur between stoppages and when the machine is running. The faster the target chain speed is reached, the higher are the forces on the carrier chain. Take the acceleration forces
- a wear-optimized production speed can be set, whereby the production potential of a plant can be optimally utilized.
- Another advantage is the reduced space requirement of the entire system, as by the reduction of the rod spacing during production a more compact design can be achieved.
- the bulk material manufacturing plant having a raw material feeding side 10 (empty cotton swabs) and processing unit for this raw material and a lead-out side 30 of the processed products 38 (cotton swabs) has means 13 (a bladed stick cartridge) 15 for making cotton swabs on the feeding side 10 (special carriers for the blanks), 50 (device for cotton feed) for the optional multiplication of the feed of the raw material (rods and cotton wool), whereby with a corresponding reduction of the feed rate of the feed side 10 with respect to the removal speed of the processed products 38 (cotton swabs) Feeding rate or Weg slaughterrate is increased or decreased and thus at constant output of the products 38 on the feed side 10, the transport speed is reduced, whereby disturbances during processing and the wear of the manufacturing plant are reduced and the process is better controlled.
- Mean 13 a bladed stick cartridge 15 for making cotton swabs on the feeding side 10 (special carriers for the blanks), 50 (device for cotton feed) for the optional multiplication of the feed of the raw material (rods and cotton
- the carriers 15 for the optional multiplication of the feed of the raw material are made either of metal or preferably of plastic. This reduces the weight on the carrier chain.
- the carriers 15 can be designed such that a plurality of blanks can be accommodated along their length.
- Today's standard size is about two inches for a stick. By way of derogation shortened to about one inch, twice the number of blanks can be accommodated per unit length.
- the feed modules 13 for the rods and 50 for the cotton to the feed side 10 working on the one hand be present several times and be selectively switchable to turn them on or off as needed. This, for example, if one of them has faults.
- the feed modules 50, 13 can be connected so that they fully or only partially load the carriers 15.
