Definitions

  • the invention relates to a coating press according to the preamble of the main claim.
  • presses are used in which the workpieces are placed on a lower press plate on substrates set back relative to their edge so that the film fed from above can lay on the front and around the edges of the workpiece with the aid of overpressure from above and / or underpressure from below.
  • a suitable base which is kept in stock and must be available at short notice
  • these documents must be put on by hand and the work piece must be aligned with it, which means unnecessary working time and effort and possible sources of error.
  • a press with a support system for plate-shaped work pieces is known (DE 295 00 248), at which corresponds to a previous one
  • the given occupancy pattern of support plugs for the workpieces from receiving holes in a plug-in plate can be used from above in the plug-in holes arranged next to them in order to be able to place a workpiece thereon and to be lifted relative to the plug-in plate.
  • a disadvantage of such a support system is that for each pressing process based on the delivered workpieces, an assignment picture must be calculated. If, for example, it is found in front of the press that a still uncoated workpiece is missing or defective, it can only be exchanged for a workpiece of an identical size.
  • the solution of this task according to the invention results in connection with the preamble features from the characterizing part of the main claim.
  • the carriers used in the through openings of the table top which can advantageously be designed as a grating or as a plate with grid-shaped recesses, can be changed in length so that in the extended state they are longer than the tabletop thick, so that when the tabletop is placed on a flat support surface, in particular on the lower press plate, they protrude upward from the tabletop, as a result of which the workpieces lying on them are raised, only being lengthened such carriers, which are completely covered with a workpiece, so that it is ensured that all edges of the workpiece and part of the lower back are exposed in the edge area and a film on the front, the edges and slightly over a narrow edge area of the back g can be pulled or pressed
  • the solution according to the invention means that there is no need for documents of different sizes for workpieces of different sizes, since the base is now composed of many small carriers that are permanently present in the laying table and that only need to be activated, ie extended, when necessary. which are not or only partially covered with a workpiece, remain or are shortened
  • the laying table can be freely occupied with workpieces in any arrangement without the laying sheet having to be calculated beforehand, since the length adjustment of the supports only takes place after the laying. Nevertheless, the use of a computer is not excluded, so that also with a calculated, optimized laying plan can be worked, the supports being able to be set before covering.
  • the supports are each provided with an upper support plate, which is larger than a passage opening and which has Its underside rests on the top of the table. The support surface for the workpieces is thus significantly increased
  • REPLACEMENT BLA ⁇ (RULE 26) aligned
  • the corners themselves are either very rounded or provided with a larger chamfer, so that even when the supports or support plates lie close together, an area of the table top delimited by the supports or by the edges of the support plates remains free.
  • This free area can preferably be can be used to arrange sensors or parts thereof in the underlying opening in the laying table, such as windows or lenses for light penetration or that it is used as a free measuring opening to overlay a workpiece via an optical distance measurement Detect
  • the change in length of a carrier can be done manually, partially or fully automatically.
  • a carrier consisting of two bolted together carrier parts by screwing in or unscrewing a part
  • other two-part carriers by clamping slide in unfolding, telescoping, etc.
  • a change in height can also be achieved simply by repositioning or placing on another side surface.
  • Such an effect can furthermore be achieved in that a one-piece support can be pivoted about an axis of rotation which is spaced differently from two flat support surfaces for the workpieces.
  • a rocker is articulated on the support, at the end of which an extension piece is attached such that it can be pivoted from a position to the side of the support into a position below the support, in which rests extensively on the lower end face of the carrier and mechanically extends it mechanically in vertical pressure. It is advantageous if the swivel axis has so much radial play in the carrier that the pressing force of the press is not via the joint, but rather positively from the extension piece is transferred to the carrier
  • the extension piece of a first embodiment of the invention to ensure and improve its function has a catch which interacts with the catch of a driver.
  • this driver is advantageously arranged on a measuring carriage of a set-up station, which is below the tray carriage is arranged displaceably, the driver via an adjusting means designed as a lifting cylinder, the driver arm
  • SPARE BL ⁇ (RULE 26) can raise or lower.
  • the catch of the driver engages in the catch of the extension piece in such a way that when the measuring carriage moves further, the extension piece is pivoted about an articulation on the carrier from an approximately horizontal position next to the carrier into a position perpendicularly below the carrier.
  • This type of extension of the carrier is mechanically very simple and therefore very robust and extremely stable and resistant to the vertical pressure forces that occur. Resetting, shortening the straps, is carried out by simply pivoting the extension pieces back, for example by means of a bar which is moved along under the table top and moves the extension pieces back in their positions next to the straps.
  • the measuring carriage is provided with a measuring wheel serving as a displacement sensor, which rolls below the table top on the latter.
  • the measuring trolley is equipped with sensors pointing upwards, which can detect workpieces lying on the supports through the free areas or windows in the table top.
  • the size of the workpiece can also be recognized in connection with the displacement transducer.
  • the detection takes place preferably via light-sensitive sensors and a light source above the table top, via infrared distance measurement or in other known ways.
  • a display and set-down table is arranged under the laying table, which can either be raised in a position in which all extended supports can be raised to control the function or the laying pattern, or in a laterally offset position can be raised and lowered, the magnetic tracks arranged on it line by row attracting the extension pieces of the supports provided with perforated metal sheets and folding them over into an extended starting position.
  • the swiveling back can then either take place again via a measuring carriage or via a permanently mounted measuring device, via which the laying table moves on the way into the press. It is particularly advantageous if the carrier plates of the carriers are thicker than the extension pieces, since then no gap is created between two adjacent and differently long carriers, but only a shoulder. This enables the simulation of so-called areas not covered with workpieces
  • REPLACEMENT BLA ⁇ (RULE 26) Clamping strips, which are also placed under the press in some workpiece molds to stretch the film and which then have to be removed again and freed from the film for further use.
  • Another advantage is that a large number of older presses can be used with the inventive laying table and such a device does not necessarily have to be arranged underneath the table top, it could just as easily recognize workpieces from above.
  • the press can be connected to a computer that calculates optimized occupancy images or even via a assigned workpiece feeder fully automatic occupancy of a table It is also possible to switch off the extension of the supports in sectors, in order to conventionally cover such a sector with documents underneath the workpieces, which is required for complicated workpiece shapes An advantageous further development of the inventive way of supporting workpieces in continuously operated presses is also conceivable
