Abstract

Mfg. extensive, flexible sheets of textile or textile composite material by means of cutting equipment, welding or sewing stations and winding appts.comprises: automatic removal of a fabric roll from a store according to a mfg. program in memory and transfer to cutting equipment; subsequent automatic electronic measurement of the web's breadth, pattern or strip size; lengthwise cutting of the web, as it is drawn in, by several thermal or ultrasonic knives; mechanical transfer through a right angle turn from the cutting equipment to a sewing etc. station where the web is moved back and forth for the sewing of seams and hems; rhythmic attachment by sewing etc. of at least two. pref. three parallel welts or weather strips in one procedure with simultaneous separation of a valance; mechanical transfer of the cloth and valance to a further sewing etc. station where the valance according to pattern is cut out and simultaneously bound by sewing etc.; while overlapping the last the welt is drawn into a groove on a hollow tube and wound up with the cloth at right angles to the previous process direction. The sequence of hollow shafts is that of the cloths to be made up according to the program and the individual controllers for process stages are synchronised with the overall flow so that individual procedures fit one another in time. Pref. after clamping the start of the fabric roll, measurement is carried out by fixed video camera or travelling sensor and the web is cut transversely. In a double needle sewing station the first hem is sewn, the head turned 180 deg. , the web seam sewn, the head turned 180 deg. and the procedure repeated for the required number of webs. The joined web is either rolled up or spread out transversely w.r.t. the sewing direction and sent to the next station. After clamping, sewing machines, or welding heads, travel in to attach three welts, one on the left and two on the right, where a cutter moves in simultaneously between the two right welts to separate a valance if required. After sewing etc. the welts are cut. In the next stage the suction-clamped valance is measured similarly to the main piece and it is cut to shape and bound with tape. The valance is laid in with the cloth which has been rolled on a hollow tube and the whole wrapped in packing film.

Description

The invention relates to a method and a device for packaging Large-area flexible fabrics made of textiles and textile composites such as awning cloths, tents, tarpaulins, roller shutters, shading curtains, Textile roofs, welding and separating curtains and the like Made-up products consisting of composite and rectangular Teilbahnen consist, according to the preamble of the main claim sewable or weldable materials.

The hitherto known methods and devices for processing large-scale flexible products of the type mentioned are based on manual labor or the partial automation of individual operations. In most cases, the fabric roll is off taken from a shelf, submitted to the cutting machine, manually cut to length and folded or wound for ease of handling, then sewed together and lined in the web direction, flounces off and cut out, this bordered, now transverse to the web direction with Keder stitched, and now the finished fabric on the so-called Cloth shaft wound and mechanically mounted.

It is known that textile rolls in paternoster, Dornstapelanlagen or Suspension conveyors are stored and from there automatically Cutting plants can be handed over. In DE OS 41 12 963 is moreover, a Stoffzuschneidevorrichtung described in the Awning cloths in length and width can be cut with help a computer program, and then the fabric nährichtig be automatically rolled up. The DE OS-42 11 219, however, transfers Fabric blanks in flat condition to different acceptance tables with the help a conveyor belt.  

To connect the cut parts by means of seams, in DE OS 37 19 188 proposed that held on a suction table Sewing cut pieces with a forward and backward stitching sewing head, wherein a hanging on a bogie sewing machine is used. There also weldable textiles are increasingly used, proposes DE-P-30 36 402 a welding device before only for web welding and Seam welding of straight textile parts, preferably awning cloths.

Another sewing device for connecting large-area layers describes the DE-PS-39 38 243, in which a movable carriage the fabric emotional. The DE-GM-92 17 012 has a device for preventing the Wave formation of a fabric to be sewn with a piping to the object. In DE-OS-41 36 069 and 42 12 867 a device is still described for cutting curves in a textile web along a marker or woven threadbare alley.

The known prior art describes individual elements for confection large parts, but without a holistic solution of individual Subassemblies, which are then linked together and with computers or Controllers can be networked to create an integrated Confection system.

The known state of the art thus has the following disadvantages:

• - The fabric storage is in roller bearings after the paternoster, Thorn stacker or roller bearing principle carried out in direct loading the cutting machine and controlled by the host, but only is turned off on the concerns of cutting, and not on the of the Sewing.
• - The cutting takes place at cutting plants, controlled by the computer become. Here are plants to mention that in different versions in the Use are, which disadvantageous at the moment still the manual measuring of the Fabric width and the strip division is, the ultrasound cut or  thermal cut does not take place at the fabric hood, and the rolling up The substances are time consuming.
• - When web sewing, the moving sewing tables are mobile Sewing machines replaced. The disadvantage here is the previous roles of Tracks and the idle stroke when returning the sewing machines.
• - When welding, the technique is limited to single welds.
• - The Volantzuschnitt is done practically everywhere by hand, with a Volantschneideanlage is in use as a prototype, but in the Stripe division of striped fabrics cumbersome manually entered must become.
• - The sewing is done by hand, partly with sewing machines, Also, a two-head system is known, but cumbersome too load, and must be operated by two people.
• - Volanteinassen, z. As in awnings and tents, is done practically everywhere by hand with sewing machines, also ultrasonic systems are in the Use that does not meet the quality requirements.
• - Also the keder welding and valance welding is done by hand carried out.
• - The chaining takes place in almost all solutions by pallet weighing or Bundle weighing, wherein Stoffknickung is unavoidable, since the substance partly rolled and folded, furthermore, because the parts are very large and handling intensive.
• - At all cutting and sewing machines / welding machines are indeed Increasingly used PCs, but is a computer communication between individual modules not yet realized with far-reaching disadvantages for Control and organization of the clothing factory. Special  Disadvantages arise for the manufacture of awning towels and Sunscreen textiles with pronounced seasonality, in the to deliver within a few days.

The operations z. B. in the awning and sunscreen assembly yourself in today

• - cut
• - side seam / web sewing
• - valance cutting
• - Keder sewing
• - Volanteinassen

in the normal awning with loose valance. Time studies revealed the following Average time shares for the specified operations:

- Cutting | 25.9% - hem / lanes 18.6% - Volant Z 26.7% - piping N 16.9% - Volant N. 11.9% 100%

The production times are also highly dependent on size, and a Clock compensation is hardly possible, so that work with intermediate buffers got to. The operations and the process steps within the operations Almost all are serially connected in series, so that long and different lead times arise. These are strong too depending on size.

Based on this state of the art and the described organizational boundary conditions should now be an invention task Confectioning system for large-scale products are developed, the

• - removes fabric rolls from a fabric store according to planning data
• - This trimmed with and without pattern consideration when fabric removal
• - Feeds a hem and web sewing unit and there in sections stitched  
• - This now feeds a Kedernähanlage, at the same time at least sewn on two piping and / or a valance with cut off
• - then passes the valance of a cutting / sewing unit, on the under pattern consideration of the valance cut and at the same time is bordered,
• - At the same time, the pre-fabricated cloth moves into a tubular shaft, this Roll up the cloth and transfer to an assembly station.
• - Furthermore, all sewing stations should also be equipped with textile welding stations alternatively can be replaced.

In accordance with the task, therefore, a confectioning system is to be developed, which the Number of process sections significantly reduced and operations in parallel to reduce production times by more than 50% to 70%. This clothing system should be able to

• - Cross processed textile cloths with top and bottom patch piping, z. B. so-called broad awnings,
• - Textile cloths processed in webs with top and bottom Piping, z. B. so-called normal awnings,
• - Textile cloths processed in webs with piping on top and bottom and with valance to be separated with piping and edging,
• - to process up to the size of at least 7000 mm × 5000 mm,
• - furthermore weldable textiles.

In a special embodiment of the invention also sewed piping or so-called hemstitch can be processed on the confection system with minor changes, whereby the individual system blocks are concatenated or individually, and the associated controls networked with each other.

This task is characterized by the characterizing features of Main claim and the associated claim of the inventive method and the device for packaging large-area flexible fabric solved.

Of particular importance are

• - The automatic removal of a textile bale from a warehouse, which is above or below the attachment is after a stored Production program and transfer to a cutting plant
• - following automatic width pattern or strip measurement with electronic measuring means, or optical methods,
• - Following longitudinal section during the withdrawal of the panels with several on and off thermal cutting blades or Ultrasonic,

• - Clockwise stitching of at least two, preferably three parallel running piping in one operation, and simultaneous separation a valance at Kederaufnähen,
• - Transfer of the cloth and valance by mechanical means in another Cutting / sewing station with prior optical measurement, thereby dessinrichtig cut out the valance and at the same time borders,
• - Where overlaps with the drawn into a groove Keder with cloth is wound at right angles to the previous working direction,
• - And thereby the order of the hollow shafts to be processed Sequence of wraps to be made up by program,
• - And the individual controls of the procedural sections with the Overall process are synchronized to the processes together adapt.

This is done, for example, in sewing methods with the technical means of a chained cutting machine for longitudinal and transverse cutting 3 , a first sewing unit for seaming and sewing 4 , a second sewing unit for sewing cords 5 , a cutting and sewing unit for valance 6 and a device for the cloth feeder 7 and the cloth winder 8 and pre-assembly. In a particularly advantageous embodiment over the prior art addition are provided according to the invention

• an optical width and strip measuring device 9 on the cutting unit 8
• - A trigger-staple carriage with individual, motor-adjustable brackets 10 on the cutting table 11th
• a sewing-up sewing module with a rotating sewing head 32 for side seaming / web sewing 12 of the textile cloths 2

FIG. 10A is a diagram of the linking possibilities of the individual devices

Fig. 10B is a flow chart for the communication of the systems with each other.

As shown in Fig. 1, the entire clothing system consists of

• - computer controlled fabric storage
• - Manufacturing modules for
• - Cutting / longitudinal section 3
• - sewing seams / webs 4
• - Sew on the welt / cut off the valance 5
• - cut / fill valance 6
• - Wind up the cloth 7
• - flexible linking 18
• - Computer communication 85 and organization.

Due to the analysis of the working sections, there are only 5 sensible production modules with minimum time and personnel requirements that can be more or less concatenated with each other. These ready-made modules are so
Z = cut
N = sewing
K = Kedern
V = valance
W = Wind cloth on shaft.

It seems possible, even when using the individual modules as Island solution to reduce the clothing time by 50%.  

However, due to the unequal cycle times, there are buffers between them Manufacturing stations. Through meaningful linking to production systems There are further improvements and savings.

The cutting module 19 of FIG. 2 consists of a fabric processing, in which from the fabric storage of the fabric bales is automatically loaded with controlled fabric handling 20th Furthermore from

• - error scanner for error marks 11
• Width and strip measuring device 9
• - automatic sheeter, cutting back and forth 22
• - Double ultrasonic cutting device for longitudinal cuts 23rd
• - Visual control panel 24
• - Clamp carriage with individually adjustable motor brackets 25
• Computer control with path calculation 26 for the number of tracks and symmetry of the residual strips
• - Transfer device and storage magazine 27 for cut webs 28th

In contrast to previous systems, the fabric width and strip division is measured automatically and the longitudinal section is carried out with 1 or 2 ultrasonic heads 23 in Klammerschlittenanzug. This saves about 40% of the time compared to previously.

In non-chained use, a storage area is still needed for the flat blanks, since no more rolls are made; Here are known layer magazines 27 can be used.

When seaming and Bahnennähmodul 12 of FIG. 3, the webs are now processed with flat

• - A moving sewing head 32 which is rotatable and can sewn the seams / tracks in front of backwards to avoid idling, with lockstitch / double chain stitch can be used.

The tracks are - coming from the filing - manually or automatically submitted to a stop 29 aligned with sensor control 30 , the Seitensäumer swung and sewn, inserted a part of the web apparatus swung and sewn, etc., the Seitsäumer swung and sewn the last part of the web.

When sewing the webs are stuck by two-sided suction strips 31 in front of and behind the sewing head 32 . The sewn web is in each case further indexed by the auxiliary transport 34 , and wound up edge-to-edge behind the system 36 . The wound roll is mounted by a handling device 36 in a paternoster 35 of FIG. 4. This only applies if not linked. The saving is about 45% of the time because the idle stroke is eliminated, and no rolling of the parts is needed. When chaining with the following Kedernähanlage 13 would be transported directly into this, as shown in Fig. 5. The entire web sewing system is slidable slide on the left 77 to handle concatenation on the piping wide awnings, furthermore, to sew separately webs can in case of failure of the piping or towels with Kedersaum, which is particularly advantageous.

Since this system is very complex, the sewing machine with appropriate sensors such as thread monitor, fabric sensor, etc. will be monitored, the system is CNC-controlled 84 , and this communicates with the EDP 86 .

The card sewing module according to FIG. 6 is based on welted piping and on valance and non-flounced and wide awning with patented piping on both sides. Cloths with piping hemstitch can be sewn on the machine if they are cut in front of the machine and the seam folded beforehand.

In contrast to a plant in which with two sewing heads of each sewn from opposite corners, after the valance was previously sewn was cut off, and that 2 people are needed to insert, will be here proposed:

• - Sew on 3 piping at the same time, and when sewing, separate the valance.

For this purpose, a web-sewn awning rolled up in the system in unclogged plant of FIG. 4 from the magazine paternoster out. This can be done by one person. The cloth is passed through web guides 60 and pulled by the staple carriage 61 so that it can be sewn at an angle and tightly.

The piping is fed from roll 52 and automatically cut - a puller 63 supports the Nähtransport. Staple carriage movement and sewing speed are electronically synchronized. On the left a left sewing machine 62 is used, on the right two right sewing machines 51 , 53 . This is necessary to disengage a machine without valance, since there is no 4-needle machine with removable needles. Between the two right Keder machines is a cutting device 14 , which separates the valance in the space between the piping. For towels without flounce, the fabric edge can be trimmed.

For the processing of wide awnings, a under-table paternoster 54 is installed under the piping mower with a number of cloth rolls. In front of the sewing heads to an automatic cross-cutting machine 64 is with ultrasonic knife for cutting the wide awning 49, as drawn in Fig. 5 and Fig. 6.

The sewing machines are again equipped with corresponding sensors such as thread monitor and material detection as well as with a multi-axis CNC control 84 and EDP communication 86 .

The process is as follows:

• - all sewing heads 51 , 53 , 62 are outside the sewing field
• - The staple carriage 55 is in the forward position and is open
• - the cloth edge is inserted, the clamp closed, the Sewing heads are in sewing position, the cloth is sewn and the valance separated.  
• - If the cloth is sewn, the clamp moves to the end position, opens, puts it Towel, and moves in rapid traverse back to the loading position forward.

When interlinking with the follow-up system is transported by the web sewing machine 4 automatically to save time and ease of handling.

If the system is not linked, the cloth is manually handled by the operator rolled up / folded in winding direction, and taken out with valance for Border / valance, assembly / cloth, which is equally in manual mode necessary if the previous or next station has failed.

In the valance module according to FIGS. 7A and 7B, individual flounces or complete sheets, if the unit is not linked with the preceding one, can

• - be cut and edged at the same time.

The plant is made up of

• - A chuck table 67 with tray and suction 75
• Width measuring and strip measuring device 16
• - Two independent linear guides 73 , 74
• mechanical cutter 75
• - Tangentially pivotable sewing head 71 with tape feed 69th
• and CNC control 84 .

In the insertion position of the sewing head 71 is left and the cutter 74 right.

The valance strip or the cloth is aligned to stop or laser marking, positioned by suction 75 and clamped with the clamping bar 67 . First, the cutter 74 moves from right to left at rapid traverse and measures with an optical probe 16, the width and the stripes and the seams of the flounce or with a video camera at a standstill. From this the computer calculates the symmetry of the valance to the cloth, and from the left the nibbler 74 begins to cut. Since the Volantkrümmung is known in the computer, moves from the left now the sewing head 71 from the edge, and summarizes the valance. For this purpose, the sewing head 71 is tangentially pivotable, the sewing machine is a zig-zag machine or straight stitch machine with merging binding 70 , tape feed and tape cutter 69th At the seam end is locked, the binding tape welded, the clamp open and the nibbler 74 stops right; the sewing head 71 returns to the left to the starting position. The valance is removed manually, or automatically transported to the winding station 8 when linking. The sewing machine is equipped with appropriate sewing sensors, such as thread monitor and cloth end detection.

The savings are about 60%, because in conjunction with the Volantabtrennen the entire operation Volantzeichnen, -schneiden deleted, since this is integrated into the respective processes, from which special advantages consequences.

With the winding module 8 of FIG. 9, the sewn, curved awning to be pulled onto the fabric shaft 79 and wound up automatically. For this purpose, the piping is fed through a feed hopper 7 in the correct position presented cloth shaft 79 , the cloth wound up by winding motor 78 and a pivot unit 80 , 82 presented in the winding frame, where then filed valance and foil and pre-assembly work done. The winding module 8 requires a perfect planning and control, since the respective automatically positioned cloth shaft 79 must fit to the cloth being processed or vice versa. Any error leads here to incorrect cycles of the entire system with manual intervention, which is why the manufacturing program by computer communication on the merger of matching cloth 49 and shaft 79 is pre-planned.

As mentioned, the individual modules according to the invention can be used independently of one another and already provide 50% time savings. However, the modules can also be used in different linking possibilities, which results in different times, and different throughput times and flexibility. There are the following 8 chaining possibilities of Fig. 10A with various advantages and disadvantages when the take-up module is taken out.

Since the cycle time results in each case by the longest time share, all the links determine the performance. Since it depends on the highest number of people with as few people, only the links of Fig. 10A are useful. The total chaining to a transfer system 1 is shown in FIG. 1. The links themselves are carried out by known linear transfer modules / conveyor belts. Since the clothing modules according to the invention are all equipped with computers 84 , networking of the installations with the EDP 86 and a control PC 85 according to FIG. 10B results. This allows a targeted just-in-time production of the awning from the customer or delivery date with constant monitoring of manufacturing progress and synchronization of the fabric production with the wave provision.

Fig. 1 shows that the entire concatenated system consisting of the modules

• - Cutting 3
• - Web sewing 4
• - Kedernähen 5
• - Cut / sew valance 6
• - winding 8
• - fabric storage 54

in a range of 20 × 30 meters.

The material storage takes place in paternoster or hanging systems above the linked system or under the plant 54 .

It is readily according to the invention that the sewing machines through Textile welding machines can be replaced with weldable textiles.

The improvements according to the invention thus result in an accelerated fabric manufacture in the sewing or welding process with short production times and throughput times by eliminating unnecessary idle times and uniform and better quality than the previous manual work. Also, the garment system 1 can be used in various stages of development and chaining and piece production. In this respect can be spoken of an ideal solution of the presented invention task.
