Definitions

  • the present invention relates to a system for detecting and cutting flat web material, in particular animal skins, according to the preamble of independent claim 1. Furthermore, the invention relates to a method for detecting and cutting flat web material according to independent claim 12.
  • Such systems and methods for detecting and cutting flat web materials are known in principle from the prior art.
  • the conventional systems and methods are particularly suitable for cutting a variety of types of flat web materials, which may be irregular in so far as they may have different sizes and shapes and / or defects.
  • These systems and methods are used, for example, for cutting flat web materials for the production of upholstery in motor vehicles, for upholstered furniture, shoes and other fabric articles.
  • the term "flat web material" is used in the sense of general flat materials which are suitable for the production of the aforementioned articles. While the use of animal skins is preferred, the invention is not limited to only workpieces made from animal skin, but also includes the use of the plant or method for other workpieces of different flat materials.
  • the present invention has for its object to provide a system and a method for detecting and cutting flat web material, which allows a particularly simple and above all inexpensive processing of flat web materials.
  • the present invention relates to a system for detecting and cutting flat web material, in particular animal skins, which has a first work table with a first work surface for laying flat web material. Furthermore, the system according to the invention has a second work table with a second work surface for laying flat web material.
  • a cutting device provided with a cutting tool. This cutting device comprises means for moving the cutting tool, which are adapted to move the cutting tool between the first and second work table such that the cutting tool can optionally be used for cutting flat web material on the first work surface or for cutting flat web material on the second work surface ,
  • two work tables are provided, which are mutually opposed and can be serviced in parallel by an operator.
  • a first flat web material is first placed on the first working surface of the first work table.
  • the operator can use the time for placing a second flat web material on the second work surface of the second work table.
  • the cutting tool can be moved by the means for moving to the second work table, whereupon a cutting operation on the second flat web material is performed immediately.
  • the operator may in turn use the time to clear the cut parts of the first flat web material from the first work surface and place a new flat web material on the first work surface.
  • the means for moving the cutting tool have a cutting bridge, which is arranged on a linear guide.
  • the linear guide is in particular designed to move the cutting bridge between the first and second work table back and forth. Since the cutting bridge in particular must be linearly movable only in one direction in space in order to achieve both working tables, this is characterized by a very low maintenance.
  • the alignment of the cutting tool with respect to the work surfaces must be done with millimeter accuracy in order to ensure an optimal cross-sectional image can. It is therefore conceivable that the cutting bridge has stops on each of the two work tables in order to simplify the erection of the cutting bridge in relation to the work tables.
  • this further comprises a third work table with a third work surface and at least one sensor device for detecting quality parameters of the flat web material.
  • flat web materials such as animal skins not only vary in their sizes and shapes, but often also contain defects such as scars, holes or scratches, as well as textures of different thicknesses or other quality parameters peculiar to each skin. It is therefore common practice to compare these prior to cutting the flat web materials with templates or patterns that represent the desired sections and to move these sections over the surface of the flat web materials until an acceptable arrangement of the cut parts is achieved. This method is referred to as "nesting", wherein the resulting arrangement of the cut parts may have a different design form and is referred to below as a cutting layer image.
  • the designed for detecting quality parameters third work table should, of course, have a lighting which is sufficient to sufficiently highlight flaws and contours of the flat web material. Also, to facilitate the operator, it may be provided that the third work surface is inclined to facilitate eventual marking of defects by the operator.
  • the sensor device can have a camera and / or a laser scanner for detecting the contours of the flat web material.
  • a camera and / or a laser scanner for detecting the contours of the flat web material.
  • all other known means for detecting the contours of the flat web material are conceivable.
  • an electronic digitizing pen for marking defects in the flat web material.
  • the markings of the electronic digitizing pin must not be visible on the surface of the flat web material, so that they do not have to be taken into account when cutting the individual pattern pieces.
  • the digitizing pen preferably has a function with which markings on the flat web material can be corrected directly. Due to the electronic digitizing pen, it is possible to detect defects in the flat web material with particularly high accuracy.
  • electronic digitizing pen which of course requires manual operation by an employee, the detection of defects can of course be done automatically, for example by the camera. By combining an automatic camera or a laser scanner with an electronic digitizing pen highest accuracy requirements can be met.
  • the third working surface may comprise a conveyor belt, which is designed to pass the flat web material past the sensor device.
  • the conveyor belt should be designed in particular slip, so that the orientation of the flat web material throughout the process is the same.
  • a vacuum may be applied to the surface of the conveyor belt to contact the flat web material to fix his position.
  • the sensor device Due to the design of the third work surface with a conveyor belt, the sensor device can be designed in particular as a line scan camera, on which the flat web material for detecting the outlines is guided past.
  • an operator can continuously mark defects in the flat web material with a digitizing pen. It is intended to provide a switch for controlling the flow of the conveyor belt, which the operator can use to vary the transport speed within certain limits.
  • This switch can be configured, for example, as a foot pedal and / or as a button on the digitizing pin.
  • the camera of the sensor device can be arranged on the third work table, so that the camera can be used to detect the entire third work surface. In other words, it is therefore possible to grasp the entire outline of the flat web material at once.
  • the system according to the invention can furthermore have a computing unit with a data memory, which is connected or connectable to the sensor device and is designed to store the recorded quality parameters of the flat web material into the data memory.
  • the arithmetic unit is in particular designed to store the quality parameters of each flat web material under an individual identification number in the data memory.
  • the digitized quality parameters can be stored and managed with software for further processing.
  • each flat web material can be provided with an information carrier, such as a bar code, which carries the individual identification number of the flat web material. Thereafter, the flat web materials can be stored in a raw material storage.
  • the production planning has the possibility of ordering orders for the exact number of flat web materials required. If production planning releases the order, an employee will do the same Flat web material taken from the raw material storage and fed to the first and second work table of the system according to the invention. As already mentioned, the digitization with the arithmetic unit takes place separately from the nesting and cutting of the flat web materials.
  • the first and the second worktable may each have a device for reading the identification number from an information carrier mounted on the flat web material. This ensures that the arithmetic unit receives a feedback which has been stored on the material on the first and second work tables for cutting. Errors by the operator can thus be effectively prevented.
  • the system according to the invention further comprises a first projection device, which is arranged on the first work table, and a second projection device, which is arranged on the second work table, on.
  • the first and second projection devices are designed to project outlines and defects of the flat web material stored in the data memory of the arithmetic unit onto the first or second work surface.
  • the orientation of the flat web material on the first and second work table can be optimized. To do this, the operator merely has to insert the flat web materials into the projections imaged on the work surfaces.
  • the contours of the flat web materials in particular projected onto the work surfaces so that the orientation of the flat web material on the first and second work table exactly corresponds to the original orientation of the flat web material on the third work table.
  • the flat web material must come to rest in the same state in terms of spatial extent on the first and second work tables formed as a cutting table, as it was located at the moment of detecting the contour in the goods entrance.
  • the projection devices can be designed as a singular or as a multiplicity of beamers which are mounted so robustly on the first or second work table, so that an unplanned readjustment of the beamer is necessary. However, if this is necessary, this must be possible at short notice by the plant operator.
  • the first and second projection devices can each have a control unit which is designed to adapt a light intensity with which the contours projected by the projection devices on the first or second working surface are adjusted to the color tone of the flat web material.
  • a control unit which is designed to adapt a light intensity with which the contours projected by the projection devices on the first or second working surface are adjusted to the color tone of the flat web material.
  • the arithmetic unit is preferably designed to generate a cut-sheet image with the aid of the quality parameters stored in the data memory, which can be displayed by the projection devices on the work surfaces of the first and second worktables.
  • the projection device is designed to represent different sectional parts of the cutting layer image with different colors. This color curvature of the different cut parts facilitates the operator clearing after the cutting process. It is conceivable, for example, that different cut parts belong to different upholstered furniture. For example, these can be colored in one color while another part of another piece of furniture is illuminated in another color. Thus, the operator can easily make a sorting of the individual cutting parts. For this, he only needs to sort the same color cut parts into one and the same container.
  • the present invention further relates to a method for detecting and cutting flat web material, in particular animal skins.
  • This is a first Flat web material placed on a first work surface of a first work table and cut using a cutting tool on the first work surface.

  • the method can also have a step of detecting quality parameters of the flat web materials prior to placing the flat web materials on the first or second work surfaces.
  • the quality parameters may be outlines, imperfections or even the color of the flat web material.
  • the recorded quality parameters can be stored in a data memory of a computing unit under an individual identification number of the flat web material.
  • the method can have a step for marking the flat web materials with the individual identification number and a step for storing the marked flat web material in a material store.
  • the arithmetic unit selects one of the marked flat web materials from the data memory, which has the optimum quality parameters for an individual cut order.
  • the arithmetic unit selects one of the marked flat web materials from the data memory, which has the optimum quality parameters for an individual cut order.

  • the individual flat web materials for example, marked by barcodes or chips with their individual identification number.
  • the computer can instruct the machine operator which of the flat material located in the material store should be placed on the respective work table.
  • the method may further include a step of projecting outlines and flaws on the first and second work surfaces, the projections corresponding to the detected quality parameters of the flat web material.
  • the operator only has to put the individual flat web material into the projected outlines and ensure that slippage is prevented.
  • the method may provide that the cut-sheet image is also projected onto the first and second work surfaces.
