Definitions

  • the present invention relates to a device according to the Claim 1 and a method according to the preamble of Claim 19, i.e. an apparatus and a method for processing a material or an object.
  • Devices and methods for processing materials or objects are, for example, but known to be at far from exclusively devices and methods that when cutting out for the production of garments, upholsteryed furniture covers, car seat covers, bags, Shoes etc. require pieces of fabric from a larger piece Fabric are used.
  • Pattern is very complex and / or very complicated, the required Cut out pieces of fabric so that they each wear exactly a given sample section or that certain parts of the pattern exactly in certain places of the cut out part of fabric come to rest. This is necessary if the fabric parts or those made from them Products must have exactly a given appearance, for example, if the pattern is placed on a jacket Bags congruent with those hidden by the pockets Should be part of the jacket, or if the upholstery is covered with fabric of upholstered furniture should look exactly the same.
  • Such a fabric cut proves in two ways as difficult: on the one hand, because it must be ensured that the parts of the fabric to be cut out the pattern is cut out of the fabric at certain points need to be taken into account, and on the other hand because must be that it may be that the material from which the parts of the fabric to be cut out, not properly on the Working document is available, e.g. moved, is twisted and / or warped.
  • That the fabric may not be properly on the Working document is mostly due to irregularities in the manufacture of fabrics in textile weaving mills and / or due to irregularities in the winding and unwinding of the fabric on or from a roll of fabric, on which the fabric is usually made by the manufacturer is delivered; such irregularities can be found in can hardly be avoided completely in practice.
  • the present invention is therefore based on the object an apparatus and a method for processing materials or to find objects that are in control and Establishing the conditions to be met so that the material to be processed or the object to be processed is actually edited at the point at which it is processed should be easy, fast and under all circumstances can be carried out with the required accuracy.
  • the device according to the invention and the invention Processes are characterized in that before the actual Processing of the material or object to be processed a pattern and / or image on the material or object is projected, which is the control and / or the manufacturing of conditions involved in processing the Material or object must be fulfilled so that the material or the object in a certain place edited, enables.
  • Object of the device operator can all Control and establish conditions that meet are from the material or object to be processed actually processing the exact location that is being processed shall be.
  • the claimed device and the claimed method also enable control and manufacture the conditions to be fulfilled always simply, quickly, and to do it with the required accuracy.
  • the device described is a device for cutting out of fabric parts from one a regularly recurring Patterned fabric, the cutting out is done so that the cut out parts of fabric or the products made from it look exactly as desired.
  • the substance is one on a roll or a bale of fabric. Insists on this too no restriction.
  • the starting material to be processed can in principle have any shape and any Way to be provided; it can also are more or less large pieces of fabric, one after the other to be edited.
  • the device under consideration comprises a frame 1 for receiving a roll of fabric 2, a work table 4 for processing one of the fabric 3 rolled off the fabric roll 2, one Projection unit 5 for projecting a pattern and / or Image on the fabric 3 on the work table 4, and one formed in the example under consideration by a computer Control device 6 for controlling the fabric processing.
  • the fabric 3 has a width between 1.8 m and 2.2 m, but of course can also can be much wider or narrower as desired.
  • the work table 4 has a length in the example considered of about 7.5 m, and a width of about 2.5 m, but can of course also much longer, shorter be wider or narrower.
  • the work table 4 and the frame 1 are placed side by side.
  • the substance 3 is by a not shown in the figures Unwinder from the roll of fabric 2 and unwound Work table 4 promoted.
  • the work table 4 contains an endless conveyor belt 45 for Transporting the fabric 3 over the work table 4.
  • the Substance 3 can also in any other way are transported over the work table 4.
  • the work table 4 has one in the example considered Control and correction area 41, a cutting area 42, and a clearing area 43; the substance 3 arrives at it Transport over the work table 4 in the first Control and correction area 41, then in the cutting area 42, and finally in the clearing area 44.
  • control and correction area 41, the cutting area 42, and the clearing area 43 are in the example considered the same size, but can in principle be independent of each other be any size.
  • control and correction area 41 there follows one control and establishment of the conditions described in more detail, which have to be fulfilled so that the ones to be cut out of the material Parts of fabric are cut out so that they wear a desired fabric sample cutout.
  • the Fabric parts to be cut out by a subsequent CNC-controlled cutting machine cut out the fabric.
  • the cutting out can be done by a knife, by a laser, or by any other Cutting devices take place.
  • the cutting device load-bearing part 421 of the cutter is attached to any slide Positions within the cutting area 42 can be positioned.
  • control and correction area 41 carried out control and production of the to be fulfilled Conditions are done using the projection unit 5.
  • This projection unit 5 is above the control and Correction area 41 arranged and projected onto the Control and correction area 41 located substance Pattern and / or image.
  • the projection takes place using of one or more laser beams of the same or different color.
  • the projection can also be done in any other way, for example using light rays; as Projection units can also use video projectors, reflected light projectors and other devices that are able to a desired pattern and / or image on the one to be processed To project material or the object to be processed.
  • the patterns and / or images mentioned can be used individually or in any combinations can be projected. It can too different patterns, pictures or picture and / or the pattern combinations projected alternately or one after the other become.
  • the projected pattern and / or image is designed and is projected onto the fabric so that it or selected Parts of the same when the fabric is properly positioned on the Work table with assigned places of the fabric sample Cover comes.
  • a correct location of the material on the Working table is when the fabric is smooth on the Work table rests, and neither from its normal position moved, still twisted, still warped.
  • the projected pattern and / or image is stored in the computer 6; this computer 6 controls the projection unit 5, so that this the pattern and / or image on the im Control and correction area 41 of the work table 4 projected material.
  • Person 7 checks whether this is from the projection unit 5 on the in the control and correction area 41 of the work table 4 located fabric 3 projected patterns and / or Image or selected parts of the same with the assigned to it Make the fabric pattern coincides, and depending on this, decides whether and if so which Corrections are to be made.
  • Aligning the fabric and / or fabric pattern to the projected pattern and / or image can, for example, by moving, rotating, stretching, pushing together, smoothing of the substance. It is in the example considered carried out manually by the person 7, since this anyway immediately next to the control and correction area 41 stands, and since this is a very easy job. In principle can align the fabric pattern to the projected Patterns and / or images can also be done mechanically.
  • the alignment of the fabric pattern with the projected pattern and / or picture is much easier in many cases and perform faster than the orientation of the projected Pattern and / or image on the fabric sample. Frequently it is enough to smooth the fabric properly.
  • the fabric sample is made using the corresponding Inputs of the person 7 into one connected to the computer 6 Input device 61. Via this input device 61 can be commanded to the computer 6 which projected pattern and / or image or individual dots or Moving, rotating, stretching, parts of it compress or influence in any other way.
  • the Computer 6 modified based on the one about it Instructions input to input device 61 the projected Pattern and / or picture and ensures that the changed Pattern and / or image by the projection unit 5 on the Material is projected.
  • the person 7 can immediately recognize how the change of the projected pattern and / or image affects, more precisely whether the correction was successful and / or whether another one Correction must be made to the projected pattern and / or Image or selected parts of the same with the assigned Make the fabric pattern coincide.
  • the computer At the latest when the orientation of the projected pattern and / or image on the fabric sample is completed the computer an adjustment of the location and / or the shape and / or the size of the patterns by which the parts to be cut out of the fabric by the cutter cut out of the fabric.
  • Such an adjustment is only when the projected pattern is aligned and / or Image on the fabric sample, but not with an alignment of the fabric pattern on the projected pattern and / or image required; with an alignment of the fabric pattern on the projected pattern and / or image can cut out the parts to be cut out of the fabric using the cutting patterns normally used.
  • How to change the pattern for this can be calculated from the type and extent to which or in which the projected pattern and / or image changes had to be with the assigned positions of the To be matched to the fabric pattern. This can be done for example by means provided in the projection unit 5 Determine sensors.
  • the computer 6 controls the cutter so that it from the material located in the cutting area 42 according to the standard or adapted to the given conditions Patterns to be cut out of the fabric Cuts out pieces of fabric.
  • Devices are each becoming a piece of fabric cut out of the fabric; this piece of fabric is with the Reference numeral 33 denotes.
  • the fabric laterally at certain intervals for example every 20 cm
  • a little e.g. 1 cm
  • Such incision of the Substance usually has the positive effect that certain delays and tensions in the fabric independently solve, and that the fabric thereby easier in its proper Location is feasible. This is because the Cutting the fabric in most cases is a so-called Selvedge is severed because of the fabric there reinforced and woven more tightly, is less stretchy than that Rest of the material and therefore often the cause of one improper location of the fabric on the work table represents.
  • the described device and the described method allow it regardless of the details of practical Realization, control and manufacture of the Conditions that have to be met in order for the one to be processed Material or the object to be processed the place where it should be processed, under all circumstances simple, fast and in the required Accuracy.
