Definitions

  • the invention relates to a transport device for flat cargo, preferably paper, according to the preamble of claim 1.
  • the conveyor belt is designed as a suction belt having a plurality of holes through which the negative pressure can act on the cargo.
  • the cargo is pulled against the conveyor belt and transported reliably by him.
  • Such conveyor belts are relatively complicated and expensive, because the holes must be subsequently introduced into the conveyor belt.
  • the invention has for its object to form a transport device of this type so that the conveyor belt can be easily and inexpensively manufactured and yet ensures a long service life and proper air passage.
  • the conveyor belt must not be provided with openings and the like.
  • the negative pressure generated by the suction device can act on the transported material via the suction gap.
  • the goods can be transported in this way properly held and transported on the conveyor belt.
  • the inventive design rework on the conveyor belt can be avoided.
  • the transport device according to the invention can be used for folding machines, inserting machines and the like.
  • the transport device 1 shown in the drawings is used for transporting flat cargo 7, preferably paper, with the cargo being held with vacuum on an endlessly circulating conveyor belt 2 of the device 1.
  • the conveyor belt 2 is guided over two driven pulleys, of which in Fig. 1, the axes of rotation 23, 24 are shown.
  • the conveyor belt 2 is advantageously designed as a toothed belt.
  • the paper 7 is under suction.
  • the upper run 3 lies in a guide 4 of a suction device 5, which is only partially shown. It is connected via a suction channel 6 to a (not shown) vacuum pump.
  • the guide 4 is formed as a profile rail. It has a recess 8 which serves as a receptacle for the upper run 3 and extends over the entire length of the guide 4.
  • the top 20 of the upper strand 3 is flush with the top 25 of the recess 8 longitudinally limiting side walls 26, 27 of the guide. 4
  • the bottom 9 of the recess 8 has a groove 10 which extends over substantially the entire length of the bottom 9 and is closed at the end (FIG. 2).
  • the groove 10 is closed at both ends by a transverse wall 16, 17 (FIGS. 1 and 2).
  • the groove 10 opens approximately halfway down the angled end 11 of the suction channel 6, which preferably sits with a press fit in an opening into the groove 10 opening 28.
  • the air can be reliably sucked out of the region of the recess 8 over its entire length.
  • the upper strand 3 is narrower than the recess 8. Due to the smaller width b of the upper strand 3 compared to the width a of the recess 8 between the longitudinal edges 14, 15 of the upper strand 3 and the inner side 12, 13 of the side walls 26, 27 each have a narrower Formed gap x. It extends over the entire length of the guide 4.
  • the two columns x are the same width. They can also be different widths.
  • the upper run 3 relative to the recess 8 to be arranged so that only at one longitudinal side of the upper run 3, a gap is provided.
  • the conveyor belt 2 is installed so that its transverse to the longitudinal direction extending teeth 18 are on the inside, so that the goods to be transported 7 facing side 20 is flat.
  • the recesses 19 located between the teeth 18 form transverse channels which open into the gaps x. This ensures that the negative pressure on the suction channel 6, the groove 10, the recess 8, the transverse channels 19 and the column x can affect the cargo 7.
  • the tape top 20 designed so that it has a relatively high coefficient of friction.
  • the tape top 20 may be formed by a corresponding coating with a high coefficient of friction.
  • the conveyor belt 2 Due to the design of the conveyor belt 2 as a toothed belt this is excellent for the start and stop operation of the device 1 suitable.
  • the conveyor belt has a long service life and also ensures the secure hold and transport of the goods to be transported, so that it is not damaged and taken properly.
  • the guide 4 is at most the same width as the cargo 7, preferably narrower than this. In the case of very wide transported goods 7, two or more such transport devices 1 may be arranged next to each other. But it is also possible to form the recess 8 of the guide 4 so wide that two or more conveyor belts 2 can be accommodated next to each other. Of course, it is possible to use a correspondingly wide conveyor belt 2 for wide cargo 7.
  • the conveyor belt 2 may also have other profiles instead of the teeth 18, which are designed so that the negative pressure generated by the vacuum pump can act on the cargo 7.
  • the conveyor belt 2 has no profiles.
  • the lateral column x suffice to bring the negative pressure to transported 7.
  • a conventional and thus inexpensive conveyor belt in the form of a flat belt is used.
  • the groove 10 is provided so that it lies below the respective gap region x.
