- An idea of the present invention is to provide a system and method for distributing a coating substance onto a thread in a controlled manner, for use in association with a thread consumption device.
- the system 10 comprises a treatment unit 100 for dispensing one or more coating substances onto at least one thread.
- the system 10 further comprises at least one thread consuming device 15, which may e.g. be in the form of one or several embroidery machine(s), a weaving machine(s), a sewing machine(s), knitting machine(s), a tufting machine(s), a thread winding machine(s) etc.
- the system thereby forms a thread consuming unit, including the at least one thread consuming device 15 and the treatment unit 100. It should be noted that more than one thread can be used in the thread consuming device(s).
- the thread consuming device 15 is exemplified as an embroidery machine, here illustrated as a single-head embroidery machine, being equipped with a treatment unit 100.
- the embroidery machine 15 comprises a moveable stage 2b carrying the fabric to be embroidered.
- the moveable stage 2b is controlled to rapidly change its position in the X and Y direction (i.e. in this case the horizontal plane, but it could also be in the vertical plane).
- the treatment unit 100 allows the embroidery machine 15 to operate without the provision of uniquely pre-coloured threads, as is required for conventional embroidery machines. Instead, the treatment unit 100 provides in-line colouring of a thread 20 in accordance with predetermined colouring patterns, such that a coloured embroidery can be produced. The treatment unit thus replaces individual thread reels as is present in prior art systems.
- the only connection between the treatment unit 100 and the embroidery machine 15 is the thread 20, as well as electrical connections (not shown).
- the treatment unit 100 is thus provided as a stand-alone unit having no mechanical connection with the moveable stage 2b.
- the stand-alone treatment unit 100 is mounted to the thread consuming device 15 via a suspension arrangement for reducing the transmission of vibrations to the treatment unit 100.
- the system 10 described herein is capable of treating one or more threads 20a- c with coating substances using only one treatment unit 100. If plurality of threads are used in the system 10, different coating substance may be dispensed onto the different threads 20a-c at the same time. Additionally, or alternatively, the coating substance may be dispensed in different patterns for the different threads 20a-c.
- Fig. 2 The various components of the treatment unit 100 configured to treat one or more threads are shown in Fig. 2. In the following the system will be described for the use of two threads, however it should be understood that the system could be adapted for a single thread or more than two threads.
- the majority, or all, of the components described for the system 10 may be arranged inside a housing.
- Each thread 20a-b is arranged to pass through a respective thread reel l20a-b.
- thread feeders l30a-b are arranged - one thread feeder l30a-b for each thread 20a-b.
- the thread feeder 130 may be configured to pull the thread forward through the treatment unit 100.
- the thread feeder 130 is not described further herein, but for a more general understanding each thread feeder 130 receives and forwards its respective thread 20a-b. For this, the thread feeders 130 may be controlled by a control unit 190 described further below.
- each thread 20a-b engages with a respective thread guiding device l40a-b.
- Each thread guiding device l40a-b which may e.g. be in the form of one or more guiding rollers or other suitable means, is ensuring that its thread 20a-b is aligned with one or more treatment nozzles forming part of at least one discharge device 150. Both the threads 20a-b then pass through the common discharge device 150.
- the discharge device 150 is configured to discharge treatment substance, such as a colouring substance, onto the thread 20 as it passes the discharge device 150.
- treatment substance such as a colouring substance
- the nozzles are arranged preferably in the longitudinal direction of the thread 20 as will be further explained in relation to Figs. 3-5.
- the discharge device 150 or parts of the discharge device 150 such as the print head(s) l5la-d (as shown for example in Fig. 3), may be moveable by means of a drive unit (not shown). Having a drive unit will make it possible to arrange the discharge device 150, or parts of the discharge device 150, in different operating states in order to perform different tasks, such as for example a first state of dispensing a coating substance to a thread and a second state of performing a cleaning session, or other maintenance or idling.
- the second thread guiding devices l60a-b are cooperating with the respective first thread guiding devices l40a-b such that the position of the respective threads 20a-b are correct during its travel along the discharge device 150.
- the second thread guiding device 160 may e.g. be in the form of one or more guiding rollers, although it may also be designed to induce a rotation of the thread 20 along its longitudinal axis.
- the system 10 may further comprise one common, or two separate, or any number of thread speed sensor(s) (not shown) configured to measure the speed of the threads 20a-b passing through the system 10.
- one common, or two separate, light detection system(s) may be arranged downstream the discharge device 150 along the travel direction of the threads 20a-b.
- the light detection system(s) is arranged to illuminate the threads 20a-b in order to receive light which is reflected from the threads 20a-b when the threads 20a- b are illuminated.
- the information gathered from the light detection signal may for example be used to determine the position of the threads in relation to the nozzles l52a- f, the width of each thread and/or properties of each thread. This information can in turn for example be used to detect nozzle(s) that are in need of maintenance, that the position of the nozzle(s) needs to be altered and/or detect variations in the coating substance.
- the light detection system(s) may be used to determine different properties of the threads that have been applied with one or several coating substances.
- the threads 20a-b are then fed forward to pass one or more fixation units 170 which are provided in order to fixate the treatment substance to the thread 20a-b.
- the fixation unit may be common for both threads, or provided as two separate units having one for each thread 20a-b.
- the fixation unit 170 preferably comprises heating means, such as a hot air supply or heated elements, or an UV light source such that the treatment substance, e.g. a colouring substance, is cured or fixated onto the thread 20.
- the fixation unit 170 may either be arranged horizontally, vertically, or at an angle between horizontally and vertically.
- the threads 20a-b may pass a cleaning unit 180, such as an ultrasonic bath, where unwanted particles are removed from the threads 20a- b.
- the cleaning unit may be common for both threads, or provided as two separate units having one for each thread 20a-b. As the treatment substance is fixated onto the threads 20a-b, the cleaning unit 180 will leave the treatment substance unaffected.
- the treatment unit 100 may further comprise a lubrication unit (not shown).
- the lubrication unit may be common for both threads, or provided as two separate units having one for each thread 20a-b. Additional thread buffers and feeders (not shown) may also be included in the treatment unit 100, arranged at various positions in the thread path.
- the threads 20a-b preferably exits the treatment unit 100 through an aperture or similar, whereby the threads 20a-b are forwarded to an associated thread consuming device, such as an embroidery machine 15 as is shown in Figs. la-b.
- an associated thread consuming device such as an embroidery machine 15 as is shown in Figs. la-b.
- a control unit 190 with associated electronics, such as power electronics, communication modules, memories, etc. is also provided.
- the control unit 190 is connected to the thread feeders l30a-b, the discharge device 150, and the fixation unit 170 for allowing control of the operation of these components. Further, the control unit 190 is configured to controlling operation of the entire treatment unit 100 including the cleaning unit 180, the lubrication unit, a disruption of the threads 20a-b, the thread speed at various position along the treatment unit 100, the thread buffers, etc.
- the control unit 190 may also be configured to receive control signals from one or more components of the treatment unit 100, e.g. control signals for triggering specific control, or other information relating to e.g. thread consumption by the embroidery machine 15.
- the control unit 190 may be implemented by any commercially available CPU ("Central Processing Unit"), DSP ("digital signal processor”) or any other electronic programmable logic device, or a combination of such processors or other electronic programmable logic device.
- the control unit 190 may be implemented using
- control unit 190 In communication with the control unit 190.
- a user interface is also provided, preferably via a display arranged at the front end of the housing.
- the display allows a user to interact with the control unit 190 and is thus connected thereto, so that the control parameters of the thread feeder 130, the discharge device 150, the fixation unit 170, etc. may be set depending on process specifications.
- the display may also preferably be used for alerting the user of critical situations, whereby the display may be used for the control unit 190 to issue alarms or the like.
- the components described above may not necessarily be included in the stand-alone treatment unit 100, but instead the components of the treatment unit 100 may be separated into several units, Preferably, the stand-alone unit includes at least the at least one discharge device 150. In one embodiment the components are not provided as a stand-alone unit, but is integrated with the thread consuming device 15.
- a discharge device 150 is shown, forming part of the treatment unit 100 as described above.
- the direction of movement of the thread(s) 20a-b in use is indicated by the solid arrow in Fig 3.
- the discharge device 150 comprises a plurality of nozzles l52a-f arranged at different longitudinal positions (for example spaced by a distance dl) along the thread 20 which passes by the treatment unit 100 during use.
- Each nozzle l52a-f is arranged to dispense a coating substance, such as ink, onto the thread 20 when the nozzle is activated.
- the coating substance is absorbed by the thread 20, e.g. at different circumferential positions of the thread 20 when the thread 20 twists about its longitudinal axis.
- the relative position of two adjacently dispensed droplets of coating substance may be selected such that the droplets will overlap.
- the treatment unit 100 comprises one or more discharge devices 150.
- Each discharge device 150 is preferably formed as a series of ink-jet print heads l5la-d, each print head l5la-d having one or more nozzle arrays.
- Each nozzle array typically comprises hundreds or thousands of nozzles. For illustrative purpose only six nozzles l52a-f are shown for one print head l5la-d; it should however be realized that each nozzle array may be provided with hundreds or thousands of nozzles 152 each.
- each print head l5la-d may be associated with a single colour; in the shown example, the discharge device 150 has four print heads l5la-d, each print head l5la-d being associated with a specific colour according to the CMYK standard.
- CMYK complementary metal-oxide-semiconductor
- the exact configuration of the treatment unit 100 may vary.
- the treatment unit 100 is provided with a single discharge device 150 having a plurality of print heads l5la-d. Each print head l5la-d is in turn provided with a plurality of nozzles l52a-f.
- the treatment unit 100 is provided with several discharge devices 150, arranged either in series or in parallel. Each discharge device 150 is then provided with a plurality of print heads l5la-d. If serially arranged, the upstream discharge device 150 may have print heads l5la-d being associated with one or more colours of a specific colour standard, while the downstream discharge device 150 has print heads 15 la— d being associated with other colours of the same colour standard.
- each discharge device 150 may have print heads l5la-d being associated with all colours of a specific colour standard, but with different threads 20.
- two separate threads 20 can be treated simultaneously and in parallel. Combinations of parallel/serial configurations are of course also possible.
- the discharge device 150 is only having a single print head l5la-d; dynamic colouring of the thread 20 would then require several discharge devices 150 of the treatment unit 100.
- Each nozzle l52a-f may dispense a coating substance having a colour according to the CMYK colour model, where the primary colours are Cyan, Magenta, Yellow, and Black. It may thus be possible to dispense a wide variety of colours onto the thread by activating nozzles l52a-f such that the total colouring substance of a specific length of the thread 20 will be a mix of the colouring substances dispensed by the nozzles l52a-f. As explained earlier, this is preferably achieved by having several print heads l5la-d arranged in series, whereby the nozzles l52a-f of a specific print head l5la-d are dedicated to a single colour.
- each nozzle l52a-f dispenses a coating substance having a colour comprising a mix of two or more primary colours of the CMYK colour model.
- the control unit 190 is configured to control the activation of the nozzles l52a- f such as the coating substance is emitted onto the thread 20 as it passes through the treatment unit 100, and especially pass the discharge device 150.
- very precise colouring of the thread 20 is possible e.g. in order to provide advanced embroidery patterns, visually extremely sophisticated by means of the colouring provided by the treatment unit 100.
- control unit 190 receives one or more input signals specifying the desired colour and/or colouring effect.
- the colour input preferably includes information regarding the exact colour, as well as the longitudinal start and stop positions of the thread 20 for that particular colour.
- the longitudinal start and stop position could be represented by specific time values if the thread speed is determined.
- Fig. 4a-b illustrates a respective top view of a print head 15 la.
- the total number of nozzles 152 of a single print head can be up to several thousands, provided on a print head 15 la in the size of a couple of centimeters. In the shown example, a far less number of nozzles 152 are shown.
- the nozzles 152 can be distributed in one or more nozzle arrays l53a-b. In Fig. 4a, the nozzles 152 are distributed in two parallel arrays l53a-b. The arrays l53a-b are aligned with each other, such that nozzles 152 of one array l53a-b are arranged adjacent a nozzle 152 of the other array l53a-b.
- Fig 4b shows a similar example, however there is a longitudinal offset between the two arrays l53a-b.
- the system 10 described herein is capable of treating one or more threads 20a- c with coating substances using only one treatment unit 100. If plurality of threads are used in the system 10, different coating substance may be dispensed onto the different threads 20a-c at the same time. Additionally, or alternatively, the coating substance may be dispensed in different patterns for the different threads 20a-c.
- the dispensing coating substance onto a plurality of threads is preferably achieved by arranging the nozzles of the discharge device 150 into several dispensing zones l54a-c that can be controlled independently.
- Fig. 5a shows a print head l5la having two nozzle arrays l53a-b.
- the nozzle arrays l53a-b are arranged in parallel with each other.
- the nozzles l52a-f of the nozzle arrays l53a-b are arranged in two dispensing zones l54a-b.
- the dispensing zones l54a-b are separated in a direction that is perpendicular to the longitudinal direction of the threads 20a-b.
- the nozzles of the first nozzle array l53a are distributed in the first dispensing zone l54a and the nozzles of the second nozzle array 153b are distributed in the second dispensing zone l54b.
- all nozzles l52a-f of each nozzle array are part of the same dispensing zone l53a-b.
- not all nozzles l52a-f of the same array l53a-b must be of the same dispensing zone l54a-b.
- the first dispensing zone l54a is configured to dispense coating substance onto the first thread 20a and the second dispensing zone l54b is configured to dispense coating substance onto the second thread 20b.
- the print head 15 la is arranged in the direction of the length of the threads 20a-b.
- the nozzle arrays l53a-b are aligned with the direction of the length of the threads 20a-b.
- the print head 15 la shown in Fig. 5a also could be defined as having ten nozzle arrays comprising two nozzles each. With this definition, the nozzle arrays are perpendicular with the length of the thread 20a, b. This situation is illustrated in Fig. 5f.
- Fig. 5b shows a print head l5la having one single nozzle array l53a.
- the nozzles l52a-f of the nozzle arrays l53a-b are arranged in three dispensing zones l54a- c.
- the nozzles that are covering, i.e. is able to dispense coating onto, the first thread 20a are distributed in the first dispensing zone l54a and the nozzles that are covering the second thread 20b are distributed in the second dispensing zone l54b.
- an intermediate dispensing zone l54c is arranged for nozzle(s) that are not covering any of the threads 20a-b.
- the print head l5la and thus its nozzle array l53a, is arranged such that it is tilted compared to the length of the threads 20a-b.
- the nozzle array l53a is thus arranged at an angle in relation to the length of the parallel threads 20a-b.
- the angle is either larger or smaller than 0 degrees.
- the nozzle array is inclined relative to the direction of the thread in order to be able to simultaneously treat more than one thread using a single nozzle array.
- the trade- off with a higher angle is that fewer nozzles per nozzle array can be utilised to colour each thread 20a-b.
- the length of the nozzle array may preferably be at least as long as the distance it takes for the thread 20 to rotate one 180° revolution around itself, and more preferably at least as long as the distance it takes for the thread 20 to rotate a 360° revolution around itself.
- means may be provided to induce a rotation of the thread as it passes the treatment unit.
- Fig. 5c illustrates a print head l5la similar to that of Fig. 5a, with the difference that the print head l5la, and thus its parallel nozzle arrays l53a-b, are arranged with an angle compared to the parallel threads 20a-b and that not all nozzles l52a-f of the same array l53a-b are part of the same dispensing zones l54a-b.
- Having both nozzle arrays inclined relative to the direction of the thread allows nozzles of both the nozzle arrays to dispense coating onto both threads 20a-b.
- the trade-off with a higher angle is that fewer nozzles per nozzle array can be utilised to colour each thread 20a-b.
- Fig. 5d illustrates a print head 15 la similar to that of Fig. 5a, with the difference that the print head comprises three parallel nozzle arrays l53a-c and three dispensing zones l54a-c. Moreover, in Fig. 5d the print head 15 la is arranged to dispense coating substance onto at least three parallel threads 20a-c.
- Fig. 5e illustrates a print head l5la similar to that of Fig. 5a, with the difference that the nozzles are distributed in six different dispensing zones l54a-f.
- Each nozzle array l53a, 153b comprises different sections of nozzles comprising different coating substance, such as different colour, as illustrated by the patterned filled nozzles in Fig. 5e.
- Each section of nozzles having different coating substances are seen as one dispensing zone l54a-f.
- Each nozzle array l53a, 153b may thus comprise different colours, with different colours for each dispensing zone l54a-f.
- FIG. 5e illustrates a print head 151 comprising two identical nozzle arrays
- Fig. 5f illustrates a print head 15 la similar to that of Fig. 5a having two dispensing zones l54a-b each covering one thread 20a-b.
- the threads 20a-b are shown having different thickness. Depending on the thickness, or width, of the thread 20a-b different number of nozzles will cover the thread 20a-b.
- the size of the nozzles of Figs. 3-5 are made large in relation to the thickness and/or width of the thread 20a, 20b only for illustrative purposes.
- the system 10 may comprise one or more encoders (not shown).
- the number of threads 20a-b in the system 10 and the number of encoders are the same, hence one encoder is provided for each thread 20a-b.
- the individual encoders are arranged to trigger dispensing signals to the individual nozzles of a dispensing zone.
- one single encoder is provided for all threads 20a-b. The one encoder is thus configured to trigger dispensing signals to the individual nozzles of a dispensing zone and/or to trigger to all dispensing zones.
- the encoder may comprise or being in communication with a wheel such as a pulley or a guiding roller.
- the encoder may for example be a rotary encoder or a shaft encoder.
- the control unit 190 is configured to control activation and deactivation of each dispensing zone l54a-c of nozzles l52a-f independently. For this, the control unit 190 may be configured to transmit trigger signals to the nozzles l52a-f being arranged in a specific dispensing zone l54a-c. Additionally, or alternatively, if the nozzles arranged in one nozzle array l53a-c are distributed into one single dispensing zone l54a-c, the control unit 190 may be configured to transmit trigger signals to the individual nozzle array l53a-c in order to activate or deactivate the nozzles of that array, and thus that dispensing zone.
- the control unit 190 may further be configured to control the activation and deactivation of the nozzles l52a-f individually in each dispensing zone l54a-b by transmitting trigger signals to the nozzles l52a-f being arranged in the specific dispensing zone l54a-c.
- the control unit 190 may further be configured to activate the nozzles of one dispensing zone l54a-c individually using a predetermined offset from receiving the trigger signal.
- the offset may for example be a specific time, length and or a
- the first thread 20a-b is arranged with a trigger for activation of the nozzles l52a-f being distributed in the first dispensing zone l54a and the second thread 20b is arranged with a trigger for activation of the nozzles l52a-f being distributed in the second dispensing zone l54b.
- Each thread 20a-b may have its own trigger for activation of the nozzles of its dispensing zone, i.e. the nozzles that are arranged in a dispensing zone covering the thread 20a-b.
- all dispensing zones are arranged with a common trigger.
- the control unit 190 may further be configured to alter the size of the dispensing zones l54a-c. Moreover, the control unit 190 may be configured to alter which nozzles that are to be distributed in the dispensing zones l54a-c. These alternations may be based on for example the thickness of the threads, the density of the threads, the number of threads to be treated, the properties of the coating substance, calibration results and/or based on the number of active nozzles.
- the control unit 190 may further be configured to alter the angle of the print head(s) l5la, or its nozzle arrays l53a-c, in relation to the treads 20a-c to be treated.
- the control unit 190 may be configured to alter the angle based on the thickness of the threads, the density of the threads, the number of threads to be treated, the properties of the coating substance and/or based on the number of active nozzles.
- all threads arranged through the system 10 are in need of in-line treatment.
- it is sufficient if one of the threads are in need of in-line treatment (such as a thread that is not pre-coloured).
- the system 10 is thus configured to handle both uniquely pre-threated threads and threads that are in need of in-line treatment at the same time.
- an embroidery machine could combine an in-line treated thread with a pre-threated thread to create a specific pattern on a substrate.
- Such a pre-treated thread could for example be a metallic, thick, thin, neon-coloured thread.
- the control unit 190 may thus be configured to determine if the thread shall be treated or not when passing through the discharge device 150. However, it should be noted that not all threads needs to pass though the treatment unit 100. This is for example the case when a thread does not need to be treated with a coating substance.
- the system 10 comprises a first and a second treatment unit lOOa, lOOb as well as a first and a second thread consuming device l5a-b.
- Each treatment unit lOOa, lOOb is controlling and performing the operations on each thread consuming device l5a-b.
- the first and second treatment unit lOOa although being separated may share one or more components.
- the control unit 190 is arranged as a separate unit from the first and second treatment unit lOOa, lOOb and one control unit 190 is thus configured to control the operation of both treatment units lOOa, lOOb and correspondingly the operation of both thread consuming devices l5a-b.
- the system 10 comprises one treatment unit lOOa and a first and a second thread consuming device l5a-b.
- one treatment unit lOOa is configured to control and perform the operation of the two thread consuming devices l5a-b.
- the term“comprises/comprising” does not exclude the presence of other elements or steps. Additionally, although individual features may be included in different claims, these may possibly advantageously be combined, and the inclusion in different claims does not imply that a combination of features is not feasible and/or advantageous. In addition, singular references do not exclude a plurality. The terms“a”, “an”,“first”,“second” etc do not preclude a plurality. Reference signs in the claims are provided merely as a clarifying example and shall not be construed as limiting the scope of the claims in any way.
