DE2118527A1 - Cloth cutter for suits - Google Patents

Abstract

Cutter is moved along two co-ordinates by computer controlled signals and the material is fed simultaneously by a second computer. This second computer is fed with data on cloth type, cutter capacity and/or position and the first is fed with material properties, size and rate of flow and possibly size and style of the pattern. The first computer can also be supplied with data on pattern spread along the path and/or the size of these and the cutters are controlled so as to ensure minimum spacing and thus minimum wastage between successive parts of the suit etc., being cut. Lasers, blade of band saws, or water jets can be used for cutting out. A bridge an be used to carry the cutters and moves up one co-ordinate axis while the cutter travels the other on the bridge. Cutting tool and time are fully utilised in an automatic process which is still variable and adaptable to customer requirements and is independent of the path limits of the cutter.

Description

Device for cutting flat material in the form of sheets or Web The invention relates to a device for cutting continuously Slidable flat material in the form of sheets or webs, with at least one Cutting member that is movable along two coordinates by means of drive members that controllable by signals of an electrionic calculating element, for example beef, in the clothing industry and also in other industries, e.g. in the Sheet metal processing, manual work occurs to a large extent. The automation Such industries are often hampered by the fact that those classified in the chain of production Machines have an improper construction, or that no machines at all available. Bezendere in the heavy clothing industry, e.g. in the pull-out, Costume and coat production could be distributed widely through automation The cutting of different parts must be done manually @@@@ dan material @ f @ mals Ralten throws or knows it.

Attempts have been made to address certain parts of the production cat to automate. For example, you have sewing machines with separate upper and lower parts, i.e. without sewing machine arm, prey to these parts according to right-angled or polar To be able to guide coordinates and automatically sew seams on a web, already cut parts.

Attempts have also been made to use a model of a certain pattern, e.g. with the help of a calculating machine to provide a model of the desired size. The model thus eriitene became the subsequent, more or less manual production based on.

That one between these two automated processes, namely the model making and sewing, the different parts of the later end product manual cut has proven to be economically and work-wise ungüns @@ g proved, with the committee thriller and the schl @@@ te mate @ alzuenut especially are non-partisan.

In a known device of the type mentioned at the beginning (USA patent document 477 322) the material to be cut is placed on a 21 @@@ and changes zeine Do not position while watching. Hardly at the size of the @@ fattening @@@ to be cut @@@@ @@@@ @@@@@@@ ch des Schneideg @@@@@ @@@@ The invention lies the object of the invention is to design a device for the host mentioned at the beginning, that with her a desired model of a desired size with full utilization the cutting capacity can be made with the pattern having a greater length should be able to assign as corresponds to the range of motion of the cutting element.

This object is achieved according to the invention. that the cutting organ displaceable material drivable at the same time with dz organ drivable by a separate drive is, the control circuit of which is supplied by a second Ausrechnungsorgen control signals that with data on the nature of the pattern and the capacity of the cutting element and or the position of the cutting element is fed, and that the first calculating element with data on the material properties, dimensions and transport speed, as well as the desired size and model of the product for which the tailored Parts are intended to be fed.

By moving the cutting element at the same time as the material by control means of the type mentioned, it has become possible that the cut to size Assign pattern a greater length than corresponds to the path of movement of the cutting element.

A significantly more material-saving separation has also become possible, because the parts to be cut can be continuously adapted to one another, that there is as little waste as possible.

During the cutting process, the fabric is normally taken from a material tree automatically placed on the conveyor belt. However, you can use the fabric or the material also manually lay flat on a conveyor belt, after which parts can be accurately and economically can crop. Usually the cutting is done in sets for each end product, e.g. a suit or sheet metal. The different parts can be very close to each other lying, with successive pattern sows moved as close together as possible will. A rotation of the cutting tool or lateral displacement of the same, Gaps or lateral shifting of the material are not necessary. A high production speed can be maintained at all times.

A device according to the invention is highly schematized in the drawing shown. 1 shows a plan view of a cutting table, Pig. 2 a side view of the table according to FIG. 1 and FIG. 3 a control device sui controlling the tailor's organ.

3 shows a central calculating element 11. In this, for example in a magnetic memory 12, a number of patterns saved from which the desired pattern can be called up. From a screaming machine 15 in connection with the calculating element 11, the cutting can be controlled. The machine 13 is used to input which models or sizes are desired, and how many copies of each pattern are to be cut.

Measurement data for a specific order as well as a specific sample, that is picked out, for example, as described in the introduction fed to a special strip or punch card reader.

The personal measurements become a measure created for each person or a measuring strip. These details are given as the calculation organ together with the other data from the reader 14 and the typewriter 13 are supplied. 15 is a control panel; and 16 a web transport assembly. From the control panel 15 from the device is put into operation, including a certain cutting speed which depends on the properties of the material to be processed is.

The output signal of the calculating organ 11 is a server server 17 for two or more drive members 18, 19 for the cutting tools.

The drive member of the transpert device 16 receives from a second Calculation element 26, which can also be singebaut in the control panel 15, eim control signal. The computation organ is both by means of lure strips, magnetic strips or the like with information about the pattern (shape of the same in relation to the displacement) as also fed by the capacity and / or the position of the cutting elements.

Memory can be especially important with a small number of patterns always bestshen from a magnetic strip 12 made of punched tape and tape reader. The electronic pattern search can then be omitted.

An automatic system according to FIG. 3 can be used in the clothing and other textile industries, be used in the paper and plastic goods, as well as in the sheet metal industry.

The cutting elements can in principle be designed according to FIGS rcrln, The son's ejaculation organ can be a laser, e.g. a CO2 laser 20 (described in "The Welding Institute Research Bulletin" Vol. 9, Sept. 1968) and cutting can be starred according to right-angled x- and y-coordinates. The control can Of course, this can also be done according to Polerkordinaten or in some other way. The beam of the laser 20 4rd by a first mirror 22 arranged on a bridge 25 and a second mirror 21 movable along the bridge, whereby the interface can be set exactly to the desired coordinate values.

Instead of using mirrors and placing the laser 20 firmly in place, can you can arrange the laser yourself on the bridge. The Schneidergan can also be one Band saw, a water jet cutting arrangement, a punch or for example rotating or reciprocating knives. When in Figs. 1 and 2, the cutting takes place exactly under the mirror 21. Afterwards the substance (or other material) fed from the warehouse is what is done by hand or can be done automatically, the cutting is done automatically until the next one Fabric feed, e.g. only pushing the fabric out of the device takes place automatically. If the fabric is faulty, cutting can be interrupted.

The fabric 25 moves at a speed that is easy to return to the cutting capacity of the laser is calculated. The fabric will held on its base by means of a vacuum. You can interrupt the laser beam and release by placing a barrier on its way, or detonating or detonating it. loosen, e.g. to cut open pockets, buttonholes etc. One can use this Also prevent the conveyor belt 24, on which the fabric 23 rests, from not burns. There. Cut out is expediently due to a there from the calculating organ 1 i controlled in digital form stored pattern. When a pattern is finished cut with, the laser beam goes to its starting position, after which the next shedding process can begin immediately. One can work for men with a total tailoring time Calculate from 30 to 60 seconds and with the subsequent operations a production cycle Aiming for a work shift of 500 excerpts. After trimming, there will be waste and Scraps of fabric sorted out so that the sample parts are suitable for their further treatment can be folded together.

Any set for a suit, such as sleeves, lapels, etc., or any set for another end product, is placed collectively on the transport belt. The rear The boundary line for each sat is measured. This rear position is used as a measurement signal fed to the calculating unit, this being the front boundary line for the next Can regulate the sentence so that it is so close to the first-mentioned rear boundary line as possible and therefore less waste.

The organs for driving the cutting organ along the various Coordinates can be electric motors, hydraulic motors or other drive means be. In the case shown, they are arranged so that they are at right angles to each other work.

The cutting elements can also additionally along a third coordinate which is perpendicular to the x and y coordinates. Through this the position of the cutting element is changed relative to the material, e.g. the depth of engagement of a knife. Only one cutting element is shown.

However, several cutting elements can also be used on the same side will.

The speed of movement of the material can be controlled in such a way that that the bridge 25 is state somewhat in the middle area of the cutting table.

A device for calculating a particular model is in the Drawing not shown * Such a device can be known per se Be personality.
