Definitions

  • the invention relates to a method and an apparatus for producing flat products from laminate, their transfer to a cover film and final assembly.
  • a device for in particular continuous transfer of isolated area products to a transport device preferably of plasters, stickers or stamps, is known. The purpose of this is to remove a punched or cut plaster from the punching / cutting device and to transfer it to a transport device in an orderly manner or to fix it to it.
  • a large number of transfer devices for flat products are known to the person skilled in the art, which have deflecting edges, transfer rollers and also wiping surfaces for releasing individual flat products to a transfer device.
  • Devices of the type mentioned are thus used to handle finished cutouts or sections or plasters when they are removed from the cutting or punching device and the subsequent transport between different transfer and / or takeover devices or stations. Work steps for the production of the plasters are not provided for in the aforementioned devices.
  • the present invention has for its object, using a prepared, almost endless laminate web, which contains components intended for the end product, from this avoiding tensile stresses in a sequence of continuous work steps with extremely little work, individual flat products with predetermined contours as far as possible Waste- Cut out the minimization and separate it from the laminate sheet in order to place it on a release liner at any point and to make it available for final assembly.
  • the invention proposes a method of the type mentioned in the preamble of claim 1, in which:
  • the contours are then brought into adhesive contact with the surface thereof by means of a transfer device, preferably a transfer roller, and the intermediate cover is pulled off by a deflection,
  • contours after deflection are laminated onto an end cover that can be used as a transport path to form flat intermediate products, and these are fed to a storage or a further processing station, preferably a separating station, and separated therein into flat end products in a manner known to the person skilled in the art and packaged primarily and / or secondarily become.
  • Another advantage of the method according to the invention is that, as a result of punching the contour against the intermediate cover, it can be selected independently of the properties of the end cover. This means that their thickness and cut resistance can be optimized for punching.
  • Another advantage results from the fact that, in order to minimize waste, the distance between the individual contours on the intermediate cover can be kept as small as the punching process requires. A punched grid can be completely omitted for contours without the necessary overhang and minimizing the punching distance. This means that the distance between the two-dimensional intermediate products when laminated onto the end cover can be chosen as large or small as desired. without increasing production waste.
  • This is particularly important in view of the fact that, depending on the punching contour, a leadframe also represents waste containing active ingredient, which on the one hand significantly increases the costs for the active ingredient and on the other hand also the disposal costs. Material costs are also reduced when using expensive carrier materials. The minimization of waste, in particular of the leadframe, is therefore of eminent importance, which is why the possibility of drastically minimizing waste in the manufacture of flat products is a serious advantage of the invention.
  • a further advantageous embodiment of the method provides that stamping residues can be removed together with the intermediate cover, with the omission of a lead frame deduction. This measure further simplifies the method and the device required to carry it out.
  • a further embodiment provides that the material and strength properties of the intermediate cover required for counterpunching can be selected and optimized based on experience.
  • an inexpensive plastic film material can be used, with the method according to the invention having the further advantage that the material used for the intermediate cover can be reused in some cases after deduction from the processing process, thereby greatly reducing the costs for this material portion or drop out.
  • an embodiment of the method provides that the punching spaces which determine the amount of punching waste are set as small as possible. In particularly favorable cases, this can lead to the absence of a lead frame for contours without lateral protrusions of the surface of the product and with minimized punching spaces.
  • the method of the invention provides that the assembly distance can be selected independently of the punching distance.
  • the contours transferred to the transfer roller lie on it at the punching distance.
  • the distance on the end cover can be selected to be larger than the punching distance.
  • a device for the production of flat products from laminate, their transfer to a cover film and final assembly, in particular for carrying out the method according to the invention is characterized in that it has a storage station for laminate, each consisting of a layer of carrier material, pressure-sensitive adhesive and intermediate covering with agents for uniform or intermittent removal of a given unit length of laminate and for conveying in sections to a contour punch, - wherein the contour punch has means for punching the carrier from below against the intermediate cover and for separating the laminate into individual contours and punching waste such as punching grid that has downstream Contour punch means for pulling off and conveying away a lead frame as well as a reel for receiving the same are arranged, that in the conveying direction after the contour punch there is a transfer device with surface adhesives for detecting and fixing individual contours, which in the beginning area of the deflection means for pulling and conveying away the intermediate cover and in the end area a transport path for feeding an end cover and means for concealing the contours with the end cover underneath Formation of intermediate products are assigned, - with the conveying means being
  • the device for producing flat products (20) from laminate (18), their transfer to a cover film and final assembly has a supply of laminate (18), each consisting of a layer of carrier material (1), pressure sensitive adhesive (2) and intermediate cover (3) with means (22) for the uniform or intermittent removal or removal of a predetermined length unit of laminate (18) and for conveying in sections to a contour punch (4).

  • the end cover (26) has conveying means (21) for evenly or intermittently pulling in and pulling out a predetermined length unit (12) from a supply reel (15).
