Definitions

  • the present invention relates to a device for removing and stacking flat objects according to the Preamble of claim 1.
  • Such a device is from DE 32 16 504 C1 known. It consists of a material web feed device with a welding and cutting device for Cutting off bag-like sections, a star wheel, whose arms when turning the star wheel with their arm ends up reach to the separation point by means of the bag-like section Pick up suction openings in the arms and after half Place the revolution on the needles of a conveyor belt.
  • the Size of the bag-like sections is here by The length of the arms of the star wheel is limited. Because the arms are the bag-like sections immediately during the separation process from from the welding station, each section comes regardless of its length, always with its separating edge or lying on the back of the arm, which is the largest Has peripheral speed.
  • the physical output is due to the short output Sections larger than long sections. Accordingly the speed of the star wheel must be short Sections are larger than for long sections. This means a greater peripheral speed for the small ones Bag. As a result of the air resistance, there is a risk that these bags detach from the suction arms. This danger must countered with a reduction in machine speed become, which leads to a reduction in efficiency.
  • the object of the present invention is to be achieved become flat, the device for removing and stacking To design objects of the type mentioned in such a way that the delivery of sections with larger and / or different Lengths from the separator to Storage device through the star wheel without reducing the Productivity is possible.
  • the invention is particularly characterized in that this device for all section sizes optimal speed can be operated without Malfunctions occur.
  • the device 1 consists according to FIG. 1 and 2 from a separating or cutting device 2 with a Feeding device for a material web 3, one as Pen stacker trained storage device 4 and one Transfer device 5 with a star wheel 6.
  • Storage device 4 and conversion device 5 can be on a common Carrier 8 may be arranged in the direction of arrow 7 for separating or Cutting device 2 can be moved towards and away from it is.
  • the star wheel 6 consists of one on two bearing posts 9 and 10 rotatably mounted hub 11 on which, for example, three or four spaced-apart planes arms 12 radially protruding are attached. Adjacent arms 12 have the same angular distance from each other. At the Close embodiment with six arms 12 per level adjacent arms 12 each an angle of 60 °.
  • the arms 12 all have the same length 13. Das Star wheel 6 is driven by a suitable drive of the arrow 14 rotated.
  • the separating or cutting device 2 separates from the Material web 3, for example a film, in particular Plastic film, each a section 15 starting from a not shown, known acceptance table or acceptance grid is put down.
  • the material web 3 is with stapling holes at a defined distance from each other 3.1 provided.
  • the sections 15 are separated so that the stitching holes 3.1 of each section 15 are always exactly the same are positioned and with pins 4.1 of the storage device 4 are in line.
  • the arrangement of the cutting or cutting device 2 and Star wheel 6 is chosen so that the free ends 12.1 Arms 12 as far as the rear edge 15.1 of section 15 reach the designated separation point.
  • the feed of the material web 3 and the separation cycle for one certain size of a section 15 are with the speed the star wheel 6 tuned so that immediately after Detach section 15 from the arms of star wheel 6 is detected.
  • the sequence of movements must be controlled that section 15 is held securely in place. If the speed is too high, the peripheral speed is transferred to the free ends 12.1 of the arms 12 so large that the section 15 bent due to excessive air pressure and by the Outer arms is pulled off. The optimal speed can be easily determined by experiments.
  • the star wheel 6 with the arms 12 is the Length 13 and the associated setting of the transfer device 5 and the storage device 4 dashed drawn.
  • the new setting with the star wheel 6 with the shorter length 13.1 of the arms 12 is in full Line width drawn.
  • the arms 12 are around here Shortened length 13.2.
  • the distance 16 for example between the axis of rotation 2.1 of the separating device 2 and the axis of rotation 6.1 of the star wheel 6 Transfer device 5 by the length 17 to the distance 16.1 reduced.
  • the device 1 it is also possible to design the device 1 so that the distance between the star wheel 6 and the transfer device 5 is adjustable. This can make an adjustment the storage device 4 to the arm length 13 or 13.1 of the Star wheel 6 can be reached.
  • the arms 12 can be changed altogether be interchangeably attached to the star wheel 6.
  • the arms 12 can also have a minimum length and through Approaches or essays can be extended. These approaches or Attachments can be screwed on, using a bayonet lock or Like. Be attached.
  • the arms 12 can also be pulled out and be collapsible. In particular, they can be telescopic can be extended or shortened.
  • the pen stacker for example that Conveyor belt 4.2, pin holder.
  • the pen holder or the conveyor belt 4.2 can have a plurality of pin holding means, for example bores, screw connections, Have tapped holes or the like. This pen holder are equidistant from each other.
  • Staple holes 3.1 can be the pins 4.1 accordingly be used.
  • the process speed of the device can be advantageous inversely proportional to the length 13 or 13.1 of the arms 12 the star wheel 6 be adjustable.
